Item 1.01 Entry into a Material Definitive Agreement.

Merger Agreement

On April 1, 2026, Cyclerion Therapeutics, Inc., a Massachusetts corporation ("Cyclerion"), Cariboos Merger Sub Corp., a Delaware corporation and a wholly owned subsidiary of Cyclerion ("First Merger Sub"), Cariboos Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Cyclerion ("Second Merger Sub" and, together with First Merger Sub, "Merger Sub"), and Korsana Biosciences, Inc., a Delaware corporation ("Korsana"), entered into an Agreement and Plan of Merger and Reorganization (the "Merger Agreement"), pursuant to which, among other matters, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, (i) First Merger Sub will merge with and into Korsana, with Korsana continuing as a wholly owned subsidiary of Cyclerion and the surviving corporation of the merger (the "First Merger"), and (ii) immediately following the First Merger and as part of the same overall transaction as the First Merger, Korsana will merge with and into Second Merger Sub (the "Second Merger" and, together with the First Merger, the "Merger"). The Merger is intended to qualify for federal income tax purposes as a tax-free reorganization under the provisions of Section 368(a) of the Internal Revenue Code of 1986, as amended.

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the "Effective Time"), (a) each then-outstanding share of Korsana common stock and Korsana preferred stock designated as "Series A Preferred Stock" will be converted into the right to receive a number of shares of Cyclerion common stock calculated in accordance with the Merger Agreement (the "Exchange Ratio"); provided, that in the event the aggregate number of shares of Cyclerion common stock issuable to holders of Korsana capital stock would result in the issuance of shares of Cyclerion common stock to a holder in excess of a specified percentage (initially set at a percentage up to 14.99%) total outstanding shares of Cyclerion common stock (such specified percentage, a "Beneficial Ownership Limitation"), then Cyclerion will issue to any such holder (x) shares of Cyclerion common stock up to such holder's Beneficial Ownership Limitation and (y) in lieu of any shares in excess of such holder's Beneficial Ownership Limitation, pre-funded warrants (the "Pre-Funded Warrants"), to purchase a number of shares of Cyclerion common stock upon exercise of such Pre-Funded Warrants equal to such excess shares, (b) each then-outstanding share of Korsana preferred stock designated as "Series Seed Preferred Stock" will be converted into the right to receive a number of shares of Series B Preferred Stock (as defined below) of Cyclerion calculated in accordance with the Merger Agreement, (c) each then-outstanding option to purchase shares of Korsana capital stock will be assumed by Cyclerion, subject to adjustment as set forth in the Merger Agreement, (d) each then-outstanding restricted stock unit award for shares of Korsana capital stock will be assumed by Cyclerion, subject to adjustment as set forth in the Merger Agreement and (e) each then-outstanding warrant to purchase shares of Korsana capital stock will be assumed by Cyclerion, subject to adjustment as set forth in the Merger Agreement. Under the terms of the Merger Agreement, prior to the closing of the Merger, the board of directors of Cyclerion (the "Board") will accelerate the vesting of all equity awards of Cyclerion then outstanding but not then vested or exercisable. Each option to acquire shares of Cyclerion common stock with an exercise price per share greater than the volume weighted average closing trading price of a share of Cyclerion common stock on The Nasdaq Capital Market ("Nasdaq") for the five (5) consecutive trading days ending three (3) trading days immediately prior to the date that is five (5) business days before the date of the Cyclerion shareholder meeting (the "Parent Closing Price") will be cancelled in accordance with the terms of the Merger Agreement. At the closing of the Merger, each option to acquire shares of Cyclerion common stock with an exercise price less than or equal to the Parent Closing Price will be cancelled and converted into the right to receive an amount in cash without interest, less applicable tax withholding, equal to the product obtained by multiplying (i) the excess of the Parent Closing Price over the exercise price per share of the Cyclerion common stock underlying such option by (ii) the number of shares of Cyclerion common stock underlying such option.

Pursuant to the Exchange Ratio formula in the Merger Agreement, upon the closing of the Merger (and prior to closing of the financing described below), on a pro forma basis and based upon the number of shares of Cyclerion common stock expected to be issued in the Merger, pre-Merger Korsana stockholders will own approximately 1.5% of the combined company and pre-Merger Cyclerion shareholders will own approximately 98.5% of the combined company. For purposes of calculating the Exchange Ratio, (i) shares of Cyclerion common stock underlying options to purchase shares of Cyclerion common stock with an exercise price less than or equal to the Parent Closing Price and other rights to receive shares of Cyclerion common stock (other than options to acquire shares of Cyclerion common stock, to the extent cancelled at or prior to closing of the Merger in accordance with the Merger Agreement) outstanding as of immediately prior to the closing of the Merger will be deemed to be outstanding (on a fully-diluted and as-converted to Cyclerion common stock basis), and (ii) all shares of Korsana common stock underlying outstanding Korsana stock options, restricted stock units, warrants and other rights to receive shares of Korsana capital stock will be deemed to be outstanding (on a fully-diluted and as-converted to Korsana common stock basis), except for certain stock options and other equity awards made to directors, employees, consultants and other service providers of Korsana. The Exchange Ratio will be adjusted to the extent that Cyclerion net cash at closing is less than or greater than $0 and will be based on the amount of proceeds actually received by Korsana in the financing transaction described below, as further described in the Merger Agreement.

In connection with the Merger, Cyclerion will seek the approval of its shareholders to, among other things, (a) issue shares of Cyclerion common stock issuable in connection with the Merger (including the shares of Cyclerion common stock issuable under the Series B Preferred Stock) and the financing described below under the rules of Nasdaq, and (b) amend its restated articles of organization to (i) change the name of Cyclerion to Korsana Biosciences, Inc., (ii) effect a reverse stock split of Cyclerion common stock, (iii) increase the number of shares of Cyclerion common stock that Cyclerion is authorized to issue, (iv) redomicile Cyclerion from Massachusetts to such jurisdiction as may be determined by Korsana, (v) designate shares of Cyclerion's preferred stock as the Series B Preferred Stock and (vi) such other changes as are mutually agreeable to Cyclerion and Korsana (the "Cyclerion Voting Proposals"). In connection with these matters, Cyclerion intends to file with the Securities and Exchange Commission (the "SEC") a registration statement on Form S-4 (the "Form S-4"), which will include a proxy statement and other relevant materials relating to a meeting of Cyclerion shareholders to be held in connection with the Cyclerion Voting Proposals.

Each of Cyclerion and Korsana has agreed to customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants relating to (1) using commercially reasonable efforts to obtain the regulatory approvals required by applicable law, (2) nonsolicitation of alternative acquisition proposals, (3) the conduct of their respective businesses during the period between the date of signing the Merger Agreement and the closing of the Merger, (4) Cyclerion using commercially reasonable efforts to maintain the existing listing of the Cyclerion common stock on Nasdaq and cause the shares of Cyclerion common stock to be issued in connection with the Merger to be approved for listing on Nasdaq prior to the closing of the Merger, and (5) Cyclerion filing with the SEC the Form S-4.

Consummation of the Merger is subject to certain closing conditions, including, among other things, (1) approval by requisite Cyclerion shareholders of the Cyclerion Voting Proposals, (2) approval by the requisite Korsana stockholders of the adoption and approval of the Merger Agreement and the transactions contemplated thereby, (3) Nasdaq's approval of the listing application to be submitted in connection with the Merger, (4) Cyclerion's Form S-4 becoming effective in accordance with the Securities Act of 1933, as amended (the "Securities Act"), and not being subject to any stop order or proceeding seeking a stop order, (5) the expiration of any applicable waiting periods (or extensions thereof) under the Hart Scott-Rodino Antitrust Improvements Act of 1976, as amended, and (6) the securities purchase agreement (described below) being in full force and effect providing for the receipt of not less than $150,000,000. Each party's

-3-

obligation to consummate the Merger is also subject to other specified customary conditions, including regarding the accuracy of the representations and warranties of the other party, subject to the applicable materiality standard, and the performance in all material respects by the other party of its obligations under the Merger Agreement required to be performed on or prior to the date of the closing of the Merger.

The Merger Agreement contains certain termination rights of each of Cyclerion and Korsana. Upon termination of the Merger Agreement under specified circumstances, Cyclerion may be required to pay Korsana a termination fee and Korsana may be required to pay Cyclerion a termination fee.

Pursuant to Articles of Amendment to Cyclerion's restated articles of organization to be filed by Cyclerion with the Secretary of the Commonwealth of Massachusetts (the "Articles of Amendment") in connection with the Merger Agreement and the transactions thereunder, Cyclerion will establish the terms of a new series of preferred stock of Cyclerion designated as Series B Non-Voting Convertible Preferred Stock, no par value per share (the "Series B Preferred Stock"). Holders of the Series B Preferred Stock will be entitled to receive dividends on shares of Series B Preferred Stock equal to, on an as-if-converted-to-Cyclerion common stock basis, and in the same form as dividends actually paid on shares of the Cyclerion common stock. Except as otherwise required by the Articles of Amendment or law, the Series B Preferred Stock will not have voting rights. However, as long as any shares of Series B Preferred Stock are outstanding, Cyclerion will not, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series B Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series B Preferred Stock, (b) alter or amend the description of rights of the Series B Preferred Stock set forth in its articles of organization, (c) amend its articles of organization, bylaws or other charter documents in any manner that adversely affects any rights of the holders of the Series B Preferred Stock, (d) file any articles of amendment, description of rights, preferences, limitations and relative rights of any series of Preferred Stock (as defined in the Articles of Amendment), if such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series B Preferred Stock, (e) issue further shares of the Series B Preferred Stock or increase or decrease (other than by conversion) the number of authorized shares of the Series B Preferred Stock, (f) at any time while at least 30% of the originally issued Series B Preferred Stock remains issued and outstanding, (i) consummate either (A) a Fundamental Transaction (as defined in Cyclerion's articles of organization) or (B) any merger or consolidation of Cyclerion or other business combination in which the shareholders of Cyclerion immediately before such transaction do not hold at least a majority of the capital stock of Cyclerion immediately after such transaction, (ii) increase the size of the Board, (iii) adopt, amend or repeal any written delegation of authority policy, corporate authority matrix or similar document, framework or schedule unless approved by the unanimous vote of the Board, or (iv) retain or replace Cyclerion's registered independent public accounting firm, independent compensation consultant or corporate counsel, or (g) enter into any agreement with respect to any of the foregoing. The Articles of Amendment provide that for so long as at least 30% of the Series B Preferred Stock remains issued and outstanding, (i) the holders of record, exclusively and voting together as a separate class on an as-converted to common stock basis, shall be entitled to elect four (4) directors of Cyclerion (the "Preferred Directors"); and (ii) the holders of record of the shares of common stock and of any other class or series of voting stock (including the Series B Preferred Stock), exclusively and voting together as a single class on an as-converted to common stock basis, shall be entitled to elect the balance of the total number of directors of Cyclerion (the "At-Large Directors"); provided, however, for administrative convenience, the initial Preferred Directors may also be appointed by the Board in connection with the approval of the initial issuance of Series B Preferred Stock without a separate action by the holders. The Series B Preferred Stock does not have a preference upon any liquidation, dissolution or winding-up of Cyclerion.

Following the closing of the Merger, each share of Series B Preferred Stock then outstanding shall be convertible, at any time and from time to time, at the option of the holder of the Series B Preferred Stock,

-4-

into a number of shares equal to 1,000 shares of Cyclerion common stock, subject to certain limitations, including that a holder of Series B Preferred Stock is prohibited from converting shares of Series B Preferred Stock into shares of Cyclerion common stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than a specified percentage (initially set at 19.99%) of the total number of shares of Cyclerion common stock issued and outstanding immediately after giving effect to such conversion.

The transaction has received approval by the Board of Directors of both companies and is expected to close in the third quarter of 2026, subject to certain closing conditions, including, among other things, approval by the shareholders of Cyclerion and the stockholders of Korsana and the satisfaction of customary closing conditions.

At the effective time of the Merger, the Board is expected to consist of six (6) members, all of whom will be designated by Korsana. Upon the closing of the transaction, the combined company will be led by Korsana's president and chief executive officer.

Financing Transaction

Concurrently with the execution and delivery of the Merger Agreement, certain institutional and accredited investors have entered into a securities purchase agreement (the "Purchase Agreement") with Korsana, pursuant to which they have agreed, subject to the terms and conditions of such agreements, to purchase immediately prior to the Effective Time, shares of Korsana common stock and pre-funded warrants (together, the "PIPE Securities") for an aggregate purchase price of approximately $380 million in a private placement (the "Private Placement"). The closing of the Private Placement is conditioned on the satisfaction or waiver of the conditions set forth in the Merger Agreement (in addition to other customary closing conditions) and is expected to occur immediately prior to the Effective Time.

The Purchase Agreement contains customary representations and warranties of Korsana, on the one hand, and the investors, on the other hand, and customary indemnification provisions. The Private Placement is also subject to approval of Korsana's stockholders which is expected to be received at the same time as the approval of the Merger.

Pursuant to the terms of the Purchase Agreement, at closing of the Private Placement, Korsana will enter into a Registration Rights Agreement (the "Registration Rights Agreement") with the purchasers of the PIPE Securities, which will provide for the registration and resale of the Cyclerion common stock issuable in exchange for the PIPE Securities upon closing of the Merger and the shares of Cyclerion common stock issuable upon exercise of the pre-funded warrants following the Merger, in accordance with the terms of the Registration Rights Agreement.

Shares of Korsana common stock and pre-funded warrants issued pursuant to this financing transaction will be converted into shares of Cyclerion common stock and pre-funded warrants to acquire shares Cyclerion common stock, in accordance with the Exchange Ratio and the Merger Agreement.

Contingent Value Rights Agreement

At or prior to the Effective Time, Cyclerion will enter into a Contingent Value Rights Agreement (the "CVR Agreement") with a rights agent ("Rights Agent") pursuant to which Cyclerion's pre-Merger shareholders will receive one contingent value right (each, a "CVR") for each outstanding share of Cyclerion common stock and Cyclerion preferred stock held by such shareholder on such date. Each CVR will represent the contractual right to receive certain net proceeds, if any, derived from any consideration that is paid to Cyclerion as a result of the disposition of Cyclerion's pre-Merger legacy assets, net of any indemnity

-5-

obligations, transaction costs and certain other expenses, during the period beginning on the date of the closing of the Merger and ending (i) with respect to the sale, transfer, license or other disposition of all pre-Merger legacy assets other than those pre-Merger legacy assets described in the following clauses (ii) and (iii), upon the second (2^nd) anniversary of the Closing Date, (ii) with respect to Cyclerion's right to receive payments under that License Agreement, dated June 3, 2021, between Cyclerion and Akebia Therapeutics, Inc. (the "Akebia License Agreement"), the earlier of (A) the fifteenth (15^th) anniversary of the date of entry into the CVR Agreement and (B) the expiration or earlier termination by Akebia Therapeutics, Inc. of the Akebia License Agreement pursuant to its terms, and (iii) with respect to the sale, transfer or other disposition of the shares of common stock of Tisento Therapeutics Holdings, Inc. ("Tisento") that were acquired by Cyclerion pursuant to that certain Asset Purchase Agreement, dated May 13, 2023, by and among Cyclerion, Tisento and JW Cycle, Inc., the earliest of (A) nine (9) months following the date of the consummation of Tisento's initial public offering pursuant to a registration statement filed with, and declared effective by, the Securities and Exchange Commission pursuant to the Securities Act, (B) the sale of Tisento, and (C) the seventh (7th) anniversary of the Closing Date.

The contingent payments under the CVR Agreement, if they become payable, will become payable to the Rights Agent for subsequent distribution to the holders of the CVRs. In the event that no such proceeds are received, holders of the CVRs will not receive any payment pursuant to the CVR Agreement. There can be no assurance that any holders of CVRs will receive any payments with respect thereto.

The right to the contingent payments contemplated by the CVR Agreement is a contractual right only and will not be transferable, except in the limited circumstances specified in the CVR Agreement. The CVRs will not be evidenced by a certificate or any other instrument and will not be registered with the SEC. The CVRs will not have any voting or dividend rights and will not represent any equity or ownership interest in Cyclerion or any of its affiliates. No interest will accrue on any amounts payable in respect of the CVRs.

Support Agreements and Lock-Up Agreement

Concurrently with the execution of the Merger Agreement, (i) certain stockholders of Korsana (solely in their respective capacities as Korsana stockholders) holding approximately 43.9% of the outstanding shares of Korsana capital stock have entered into support agreements with Cyclerion and Korsana to vote all of their shares of Korsana capital stock in favor of the adoption and approval of the Merger Agreement and the transactions contemplated thereby and against any alternative acquisition proposals (the "Korsana Support Agreements") and (ii) the directors and officers of Cyclerion holding approximately 24.2% of the outstanding shares of Cyclerion common stock have entered into support agreements with Cyclerion and Korsana to vote all of their shares of Cyclerion common stock in favor of the Cyclerion Voting Proposals and against any alternative acquisition proposals (the "Cyclerion Support Agreements," and, together with the Korsana Support Agreements, the "Support Agreements").

21

(b) If any shares of Company Capital Stock outstanding immediately prior to the First Effective Time are unvested or are subject to a repurchase option or a risk of forfeiture under any applicable restricted stock purchase agreement or other similar agreement with the Company, then the shares of Parent Capital Stock issued in exchange for such shares of Company Capital Stock will to the same extent be unvested and subject to the same repurchase option or risk of forfeiture, and such shares of Parent Capital Stock shall accordingly be marked with appropriate legends.

Notwithstanding the foregoing, by written notice to the Surviving Entity, any Person may reset the Beneficial Ownership Limitation percentage to a higher or lower percentage, not to exceed 19.99%; provided that any increase will not be effective until the sixty-first (61st) day after such written notice is delivered to the Surviving Entity.

(b) Promptly after the First Effective Time, the Parties shall cause the Exchange Agent to mail to the Persons who were record holders of shares of Company Capital Stock that were converted into the right to receive the Merger Consideration: (i) a letter of transmittal in customary form and containing such provisions as Parent may reasonably specify (including a provision confirming that (A) delivery of physical stock certificates representing shares of Company Capital Stock, (the "Company Stock Certificates") shall be effected, and risk of loss and title shall pass, only upon delivery of such Company Stock Certificates to the Exchange Agent), and (B) a holder of uncertificated shares of Company Capital Stock shall not be required to deliver Company Stock Certificates and in lieu thereof, the Exchange Agent shall receive an "agent's message" in customary form (or such other evidence, if any, as the Exchange Agent may require, with respect to such uncertificated shares of Company Capital Stock) and (ii) instructions for effecting the surrender of Company Stock Certificates, or uncertificated shares of Company Capital Stock, in exchange for book-entry shares of Parent Capital Stock. Upon surrender of a Company Stock Certificate or other reasonable evidence of the ownership of uncertificated Company Capital Stock to the Exchange Agent for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by the Exchange Agent or Parent: (A) the holder of such Company Stock Certificate or uncertificated shares of Company Capital Stock shall be entitled to receive in exchange

23

therefor book-entry shares representing the Merger Consideration (in a number of whole shares of Parent Capital Stock) that such holder has the right to receive pursuant to the provisions of Section 2.5(a) and Section 2.5(c) and (B) the Company Stock Certificate or uncertificated shares of Company Capital Stock so surrendered shall be canceled. Until surrendered as contemplated by this Section 2.7(b), each Company Stock Certificate or uncertificated shares of Company Capital Stock shall be deemed, from and after the First Effective Time, to represent only the right to receive book-entry shares of Parent Capital Stock representing the Merger Consideration. If any Company Stock Certificate shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the delivery of any shares of Parent Capital Stock, require the owner of such lost, stolen or destroyed Company Stock Certificate to provide an applicable affidavit with respect to such Company Stock Certificate and post a bond indemnifying Parent against any claim suffered by Parent related to the lost, stolen or destroyed Company Stock Certificate or any Parent Capital Stock issued in exchange therefor as Parent may reasonably request.

(c) No dividends or other distributions declared or made with respect to Parent Capital Stock with a record date after the First Effective Time shall be paid to the holder of any unsurrendered Company Stock Certificate with respect to the shares of Parent Capital Stock that such holder has the right to receive in the Merger until such holder surrenders such Company Stock Certificate or uncertificated shares of Company Capital Stock or provides an affidavit of loss or destruction in lieu thereof in accordance with this Section 2.7 (at which time such holder shall be entitled, subject to the effect of applicable abandoned property, escheat or similar Laws, to receive all such dividends and distributions, without interest).

(d) Any shares of Parent Capital Stock deposited with the Exchange Agent that remain undistributed to holders of Company Capital Stock as of the date that is 180 days after the Closing Date shall be delivered to Parent upon demand, and any holders of Company Capital Stock who have not theretofore surrendered their Company Stock Certificates or uncertificated shares of Company Capital Stock in accordance with this Section 2.7 shall thereafter look only to Parent for satisfaction of their claims for Parent Capital Stock and any dividends or distributions with respect to shares of Parent Capital Stock.

(e) No Person shall be liable to any holder of any Company Capital Stock or to any other Person with respect to any shares of Parent Capital Stock (or dividends or distributions with respect thereto) or for any cash amounts delivered to any public official pursuant to any applicable abandoned property Law, escheat Law or similar Law.

2.8 Calculation of Parent Net Cash and Company Valuation.

(a) No later than five (5) Business Days before the date of the Parent Shareholder Meeting set forth in the Proxy Statement (the "Calculation Date"), Parent will deliver to the Company a schedule (the "Parent Net Cash Schedule") setting forth, in reasonable detail, Parent's good faith, estimated calculation of the components of Parent Net Cash (the "Parent Net Cash Calculation," and the date of delivery of such schedule being the "Parent Net Cash Schedule Delivery Date") as of 11:59 p.m. on the Business Day prior to the Anticipated Closing Date (the "Cash Determination Time") prepared and certified, via certificate in the form reasonably acceptable to the Company, by Parent's chief financial officer (or if there is no chief financial officer at such time, the principal financial and accounting officer for Parent). Parent shall make available to the Company (electronically to the greatest extent possible) as reasonably requested by the Company, the work papers and back-up materials used or useful in preparing the Parent Net Cash Schedule and, if reasonably requested by the Company, Parent's internal finance personnel and its accountants and counsel during Parent's normal business hours and upon reasonably advanced written notice. The Parent Net Cash Calculation shall include Parent's determination, as of the Cash Determination Time, of the defined terms in Section 1.1(b) necessary to calculate the Exchange Ratio. During the period beginning on the Parent Net Cash Schedule Delivery Date and ending on the Calculation Date, the Company shall have an opportunity to review the Parent Net Cash Schedule and Parent shall

24

reasonably cooperate with the Company in good faith to respond to any questions regarding the Parent Net Cash Schedule raised by the Company; provided that this shall in no way limit or otherwise affect the Company's remedies under this Agreement or otherwise, or constitute an acknowledgement by the Company of the accuracy of the amounts reflected therein. Notwithstanding anything else in this Agreement, the Company may require Parent to deliver a new Parent Net Cash Schedule if the Closing Date is more than twenty (20) days after the Calculation Date, which date of delivery shall be deemed the "Calculation Date" hereunder.

(b) No later than the Calculation Date, the Company will deliver to Parent a schedule (the "Company Valuation Schedule") setting forth, in reasonable detail, the Company's good faith, estimated calculations of the components of the Company Valuation (the "Company Valuation Calculation," and the date of delivery of such schedule being the "Company Valuation Delivery Date") as of 11:59 p.m. on the last Business Day prior to the Anticipated Closing Date (the "Company Valuation Determination Time") prepared and certified, via certificate in the form reasonably acceptable to Parent, by the Company's chief financial officer (or if there is no chief financial officer at such time, the principal financial and accounting officer for the Company). The Company shall make available to Parent (electronically to the greatest extent possible) as reasonably requested by Parent, the work papers and back-up materials used or useful in preparing the Company Valuation Schedule and, if reasonably requested by Parent, the Company's internal finance personnel and its accountants and counsel during the Company's normal business hours and upon reasonably advanced written notice. During the period after the delivery of the Company Valuation Schedule and prior to the Closing, Parent shall have an opportunity to review the Company Valuation Schedule and the Company shall reasonably cooperate with Parent in good faith to respond to any questions regarding the Company Valuation Schedule raised by Parent; provided, that this shall in no way limit or otherwise affect the Parent's remedies under this Agreement or otherwise, or constitute an acknowledgement by Parent of the accuracy of the amounts reflected therein.

(c) No later than three (3) Business Days after the Parent Net Cash Schedule Delivery Date (the last day of such period, the "Response Date"), the Company shall have the right to dispute any part of the Parent Net Cash Calculation by delivering a written notice to that effect to Parent (a "Dispute Notice"). Any Dispute Notice shall identify in reasonable detail and to the extent known the nature and amounts of any proposed revisions to the Parent Net Cash Calculation and will be accompanied by reasonably detailed materials supporting the basis for such revisions.

(d) No later than three (3) Business Days after the Company Valuation Delivery Date (the last day of such period, the "Company Valuation Response Date"), Parent shall have the right to dispute any part of the Company Valuation Calculation by delivering a written notice to that effect to the Company (a "Company Valuation Dispute Notice") and any Company Valuation Dispute Notice shall identify in reasonable detail and to the extent known the nature and amounts of any proposed revisions to the Company Valuation Calculation and will be accompanied by reasonably detailed materials supporting the basis for such revisions.

(e) If, on or prior to the Response Date, the Company notifies Parent in writing that it has no objections to the Parent Net Cash Calculation or, if on the Response Date, the Company fails to deliver a Dispute Notice as provided in Section 2.8(c), then the Parent Net Cash Calculation as set forth in the Parent Net Cash Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent the Parent Net Cash at the Cash Determination Time for purposes of this Agreement.

(f) If, on or prior to the Company Valuation Response Date, Parent notifies the Company in writing that it has no objections to the Company Valuation Calculation or, if on the Company Valuation Response Date, Parent fails to deliver a Company Valuation Dispute Notice as provided in Section 2.8(d), then the Company Valuation Calculation as set forth in the Company Valuation Schedule shall be deemed to have been finally determined for purposes of this Agreement and to represent the Company Valuation at the Company Valuation Determination Time for purposes of this Agreement.

25

(g) If the Company delivers a Dispute Notice on or prior to the Response Date, then Representatives of Parent and the Company shall promptly meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of Parent Net Cash, which agreed upon the Parent Net Cash amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Parent Net Cash at the Cash Determination Time for purposes of this Agreement. If Parent delivers a Company Valuation Dispute Notice on or prior to the Company Valuation Response Date, then Representatives of Parent and the Company shall promptly meet and attempt in good faith to resolve the disputed item(s) and negotiate an agreed-upon determination of the components of the Company Valuation, which agreed upon Company Valuation amount shall be deemed to have been finally determined for purposes of this Agreement and to represent the Company Valuation at the Company Valuation Determination Time for purposes of this Agreement.

(h) If Representatives of Parent and the Company are unable to negotiate an agreed-upon determination of Parent Net Cash as of the Cash Determination Time pursuant or the components of Company Valuation as of the Company Valuation Determination Time, in each case pursuant to Section 2.8(g) within three days after delivery of the Dispute Notice or the Company Valuation Dispute Notice, as applicable (or such other period as Parent and the Company may mutually agree upon), then any remaining disagreements as to the calculation of Parent Net Cash or Company Valuation shall be referred to an independent auditor of recognized national standing jointly selected by Parent and the Company. If the parties are unable to select an independent auditor within five (5) days, then either Parent or the Company may thereafter request that either the Boston, Massachusetts Office of the American Arbitration Association or the New York, New York Office of the American Arbitration Association ("AAA") make such selection (either the independent auditor jointly selected by both parties or such independent auditor selected by the AAA, the "Accounting Firm"). Parent and the Company shall promptly deliver to the Accounting Firm the work papers and back-up materials used in preparing the Parent Net Cash Schedule and the Dispute Notice and the Company Valuation Schedule and the Company Valuation Dispute Notice, and Parent and the Company shall use commercially reasonable efforts to cause the Accounting Firm to make its determination within five (5) Business Days of accepting its selection. Parent and the Company shall be afforded the opportunity to present to the Accounting Firm any material related to the unresolved disputes and to discuss the issues with the Accounting Firm; provided, however, that no such presentation or discussion shall occur without the presence of a Representative of each of Parent and the Company. The determination of the Accounting Firm shall be limited to the disagreements submitted to the Accounting Firm. The determination of the amount of Parent Net Cash or the components of the Company Valuation made by the Accounting Firm shall be made in writing delivered to each of Parent and the Company, shall be final and binding on Parent and the Company and shall (absent manifest error) be deemed to have been finally determined for purposes of this Agreement and to represent the Parent Net Cash at the Cash Determination Time or the components of the Company Valuation at the Company Valuation Determination Time for purposes of this Agreement. The Parties shall delay the Closing until the resolution of the matters described in this Section 2.8(h). The fees and expenses of the Accounting Firm shall be allocated between Parent and the Company in the same proportion that the disputed amount of the Parent Net Cash or the Company Valuation that was unsuccessfully disputed by such Party (as finally determined by the Accounting Firm) bears to the total disputed amount of the Parent Net Cash amount or the components of the Company Valuation. If this Section 2.8(h) applies as to the determination of the Parent Net Cash at the Cash Determination Time or to the determination of the components of the Company Valuation at the Company Valuation Determination Time, as applicable, upon resolution of the matter in accordance with this Section 2.8(h), the Parties shall not be required to determine Parent Net Cash or the Company Valuation again even though the Closing may occur later than the Anticipated Closing Date, except that either Parent and the Company may request a redetermination of Parent Net Cash or the Company Valuation if the Closing Date is more than thirty (30) days after the Anticipated Closing Date.

26

2.9 Contingent Value Right.

(a) Prior to the First Effective Time, Parent shall declare a distribution (the "Closing Distribution") to holders of Parent Common Stock and Parent Preferred Stock of record as of immediately prior to the First Effective Time (including, for the avoidance of doubt, those shares of Parent Common Stock with respect to Parent Restricted Stock Awards accelerated pursuant to Section 6.6(e)) of the right to receive one contingent value right (each, a "CVR") for each outstanding share of Parent Common Stock or Parent Preferred Stock held by such stockholder as of such date (less applicable withholding taxes), each representing the right to receive contingent payments upon the occurrence of certain events set forth in, and subject to and in accordance with the terms and conditions of, the Contingent Value Rights Agreement in the form attached hereto as Exhibit F (the "CVR Agreement"). The record date for the Closing Distribution shall be the close of business on the Business Day prior to the date on which the First Effective Time occurs and the payment date for which shall be three (3) Business Days after the First Effective Time; provided that the payment of such distribution may be conditioned upon the occurrence of the First Effective Time.

(b) Parent and the Exchange Agent shall, at or prior to the First Effective Time, duly authorize, execute and deliver the CVR Agreement, subject to any reasonable revisions to the CVR Agreement that are requested by such Exchange Agent and are reasonably acceptable to the Company and Parent.

(c) Parent shall pay all costs and fees associated with any action contemplated by this Section 2.9 (the "CVR Fees").

2.10 Further Action. If, at any time after the First Effective Time, any further action is determined by the Surviving Entity to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Entity with full right, title and possession of and to all rights and property of the Company, then the officers and directors of the Surviving Entity shall be fully authorized, and shall use their and its commercially reasonable efforts (in the name of the Company, in the name of First Merger Sub, in the name of Second Merger Sub, in the name of the Surviving Entity and otherwise) to take such action.

2.11 Intended Tax Treatment. The Parties acknowledge and agree that, for U.S. federal (and applicable state and local) income Tax purposes, the First Merger and the Second Merger, taken together, are intended to constitute an integrated transaction described in Rev. Rul. 2001-46, 2001-2 C.B. 321 that qualifies as a "reorganization" within the meaning of Section 368(a) of the Code (the "Intended Tax Treatment"). The Parties adopt this Agreement as a "plan of reorganization" within the meaning of Treasury Regulations Sections 1.368-2(g) and 1.368-3(a).

2.12 Withholding. Each of the Exchange Agent, Parent and the Surviving Entity shall be entitled to deduct and withhold from any consideration deliverable pursuant to this Agreement to any Person such amounts as are required to be deducted or withheld from such consideration under applicable Law; provided that, with respect to any non-compensatory amounts, the Exchange Agent, Parent and the Surviving Entity shall use commercially reasonable efforts to promptly notify such Persons of any intention to withhold any portion of such consideration and cooperate with any requests by such Persons to reduce or eliminate any such withholding to the extent permitted by applicable Law. To the extent such amounts are so deducted or withheld and remitted to the appropriate Governmental Authority, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid. All payments made under this agreement that constitute compensation to employees for services for Tax purposes shall be made through the payroll of the Surviving Entity or Parent, as applicable.

27

2.13 Appraisal Rights.

(a) Notwithstanding any provision of this Agreement to the contrary, shares of Company Capital Stock that are outstanding immediately prior to the First Effective Time and which are held by stockholders or owned by beneficial owners who have exercised and perfected appraisal rights for such shares of Company Capital Stock in accordance with the DGCL (collectively, the "Dissenting Shares") shall not be converted into or represent the right to receive the Merger Consideration described in Section 2.5 attributable to such Dissenting Shares. Such stockholders or beneficial owners shall be entitled to receive payment of the fair value of such shares of Company Capital Stock held by them in accordance with the DGCL, unless and until such stockholders or beneficial owners fail to perfect or effectively withdraw or otherwise lose their appraisal rights under the DGCL. All Dissenting Shares held by stockholders or owned by beneficial owners who shall have failed to perfect or shall have effectively withdrawn or lost their right to appraisal of such shares of Company Capital Stock under the DGCL (whether occurring before, at or after the First Effective Time) shall thereupon be deemed to be converted into and to have become exchangeable for, as of the First Effective Time, the right to receive the Merger Consideration, without interest, attributable to such Dissenting Shares upon their surrender in the manner provided in Sections 2.5 and 2.7.

(b) The Company shall give Parent prompt written notice of any demands by dissenting stockholders or beneficial owners received by the Company, withdrawals of such demands and any other instruments served on the Company and any material correspondence received by the Company in connection with such demands, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with Parent's prior written consent, not to be unreasonably withheld, delayed or conditioned, make any payment with respect to, or settle or offer to settle, any such demands, or approve any withdrawal of any such demands or agree to do any of the foregoing.

To the Knowledge of Parent, no third party is infringing upon any Patents owned by Parent within the Parent IP Rights, or violating any Parent IP Rights Agreement.

53

(h) As of the date of this Agreement, Parent is not a party to any Legal Proceeding (including, but not limited to, opposition, interference or other proceeding in any patent or other government office) contesting the validity, ownership or right to use, sell, offer for sale, license or dispose of any Parent IP Rights. Parent has not received any written notice asserting that any Parent Registered IP or the proposed use, sale, offer for sale, license or disposition of any products, methods or processes claimed or covered thereunder infringes or misappropriates or violates the rights of any other Person or that Parent or any of its Subsidiaries have otherwise infringed, misappropriated or otherwise violated any Intellectual Property of any Person.

(i) To the Knowledge of Parent, no trademark (whether registered or unregistered) or trade name owned, used or applied for by Parent conflicts or interferes with any trademark (whether registered or unregistered) or trade name owned, used or applied for by any other Person except as would not have a Parent Material Adverse Effect.

(k) Neither Parent nor any of its Subsidiaries is party to any Contract that, as a result of such execution, delivery and performance of this Agreement, will cause the grant of any license or other right to any Parent IP Rights, result in breach of, default under or termination of such Contract with respect to any Parent IP Rights, or impair the right of Parent or the Surviving Entity and its Subsidiaries to use, sell or license or enforce any Parent IP Rights or portion thereof, except for the occurrence of any such grant or impairment that would not individually or in the aggregate, reasonably be expected to result in a Parent Material Adverse Effect.

Parent shall promptly notify the Company if it becomes aware (1) that the Registration Statement has become effective, (2) of the issuance of any stop order or suspension of the qualification or registration of the Parent Capital Stock issuable in connection with the Contemplated Transactions (including any Parent Common Stock issuable upon (I) conversion of the Parent Convertible Preferred Stock or (II) exercise of any Assumed Warrant) for offering or sale in any jurisdiction, or (3) any order of the SEC related to the Registration Statement, and shall promptly provide to the Company copies of all written correspondence between it or any of its Representatives, on the one hand, and the SEC or staff of the SEC, on the other hand, with respect to the Registration Statement and all orders of the SEC relating to the Registration Statement. The Company and Parent shall each pay 50% of (i) the fees paid in connection with filing the Registration Statement and any amendments and supplements thereto, and (ii) the fees and expenses in connection with the printing, mailing and distribution of the Proxy Statement and any amendments and supplements.

(d) The Company shall reasonably cooperate with Parent and provide, and cause its Representatives to provide, Parent and its Representatives, with all true, correct and complete information regarding the Company that is required by Law to be included in the Registration Statement or reasonably requested by Parent to be included in the Registration Statement (collectively, the "Company Required S-4 Information"). Without limiting the foregoing, the Company will use commercially reasonable efforts to cause to be delivered to Parent a consent letter of the Company's independent

71

accounting firm, dated no later than the date on which the Registration Statement is filed with the SEC (and reasonably satisfactory in form and substance to Parent), that is customary in scope and substance for consent letters delivered by independent public accountants in connection with registration statements similar to the Registration Statement. The Company and its legal counsel shall be given reasonable opportunity to review and comment on the Registration Statement, including all amendments and supplements thereto, prior to the filing thereof with the SEC, and on the response to any comments of the SEC on the Registration Statement, prior to the filing thereof with the SEC. Parent may file the Registration Statement, or any amendment or supplement thereto, without the prior consent of the Company, provided that Parent has included the Company Required S-4 Information in the Registration Statement in substantially the same form as it was provided to Parent by the Company pursuant to this Section 6.1; provided, further, that if the prior consent of the Company is not obtained then, notwithstanding anything else herein, the Company makes no covenant or representation regarding the portion of such information supplied by or on behalf of the Company to Parent for inclusion in such Registration Statement that the Company reasonably identifies prior to such filing of the Registration Statement.

6.2 Company Stockholder Written Consent.

(a) Promptly after the Registration Statement has been declared effective under the Securities Act, and in any event no later than two (2) Business Days thereafter, the Company shall obtain the approval by written consent from Company stockholders sufficient for the Required Company Stockholder Vote in lieu of a meeting pursuant to Section 228 of the DGCL, for purposes of (i) adopting and approving this Agreement and the Contemplated Transactions, (ii) acknowledging that the approval given thereby is irrevocable and that such stockholder is aware of its rights to demand appraisal for its shares pursuant to Section 262 of the DGCL, and that such stockholder has received and read a copy of Section 262 of the DGCL and (iii) acknowledging that by its approval of the Merger it is not entitled to appraisal rights with respect to its shares in connection with the Merger and thereby waives any rights to receive payment of the fair value of its capital stock under the DGCL (the "Company Stockholder Written Consents"). Under no circumstances shall the Company assert that any other approval or consent is necessary by its stockholders to approve this Agreement and the Contemplated Transactions.

(b) Reasonably promptly following receipt of the Required Company Stockholder Vote, the Company shall prepare and mail a notice (the "Stockholder Notice") to every stockholder of the Company that did not execute the Company Stockholder Written Consent, if any. The Stockholder Notice shall (i) be a statement to the effect that the Company Board determined that the Merger is advisable in accordance with Section 251(b) of the DGCL and in the best interests of the stockholders of the Company and approved and adopted this Agreement, the Merger and the other Contemplated Transactions, (ii) provide the stockholders of the Company to whom it is sent with notice of the actions taken in the Company Stockholder Written Consent, including the adoption and approval of this Agreement, the Merger and the other Contemplated Transactions in accordance with Section 228(e) of the DGCL and the certificate of incorporation and bylaws of the Company and (iii) include a description of the appraisal rights of the Company's stockholders available under the DGCL, along with such other information as is required thereunder and pursuant to applicable Law. All materials (including any amendments thereto) submitted to the stockholders of the Company in accordance with this Section 6.2(b) shall be subject to Parent's advance review (the period of time starting upon delivery of any such materials to Parent and ending upon resolution of any good faith comments raised by Parent, the "Company Stockholder Consent Review Period"), and the Company shall consider in good faith any comments raised by Parent in connection with Parent's review.

(c) The Company agrees that, subject to Section 6.2(d): (i) the Company Board shall recommend that the Company's stockholders vote to adopt and approve this Agreement and the Contemplated Transactions and shall use commercially reasonable efforts to solicit such approval within the time set forth in Section 6.2(a) (the recommendation of the Company Board that the Company's stockholders

72

vote to adopt and approve this Agreement being referred to as the "Company Board Recommendation") and (ii) the Company Board Recommendation shall not be withdrawn or modified (and the Company Board shall not publicly propose to withdraw or modify the Company Board Recommendation) in a manner adverse to Parent, and no resolution by the Company Board or any committee thereof to withdraw or modify the Company Board Recommendation in a manner adverse to Parent or to adopt, approve or recommend (or publicly propose to adopt, approve or recommend) any Acquisition Proposal shall be adopted or proposed.

(d) Notwithstanding anything to the contrary contained in Section 6.2(c), and subject to compliance with Section 5.4 and Section 6.2, if at any time prior to approval and adoption of this Agreement by the Required Company Stockholder Vote, (i) the Company receives a bona fide unsolicited written Acquisition Proposal that did not result from a breach of Section 5.4 or Section 6.2 and that the Company Board determines, following consultation with its outside legal counsel and financial advisor, to be a Superior Offer, or (ii) as a result of a material development or change in circumstances (other than any such event, development or change to the extent (A) known or reasonably foreseeable to the Company, the Company Board or any of its executive officers as of the date of this Agreement or (B) related to (1) any Acquisition Proposal, Acquisition Inquiry, Acquisition Transaction or the consequences thereof, (2) any events, developments or changes relating to Parent or Merger Subs, or (3) the fact, in and of itself, that the Company meets or exceeds internal budgets, plans or forecasts of its revenues, earnings or other financial performance or results of operations) that affects the business, assets or operations of the Company that occurs or arises after the date of this Agreement (a "Company Intervening Event"), the Company Board may withhold, amend, withdraw or modify the Company Board Recommendation (or publicly propose to withhold, amend, withdraw or modify the Company Board Recommendation) in a manner adverse to Parent (collectively, a "Company Board Adverse Recommendation Change") if, but only if, (x) in the case of a Superior Offer, following the receipt of and on account of such Superior Offer, (i) the Company Board determines in good faith, based on the advice of its outside legal counsel, that the failure to withhold, amend, withdraw or modify the Company Board Recommendation would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, (ii) the Company has, during the Notice Period (as defined below), negotiated with Parent in good faith to make such adjustments to the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Offer and (iii) if, Parent has delivered to the Company a written offer to alter the terms or conditions of this Agreement during the Notice Period, the Company Board shall have determined in good faith, based on the advice of its outside legal counsel and financial advisor, that the failure to withhold, amend, withdraw or modify the Company Board Recommendation would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law (after taking into account such alterations of the terms and conditions of this Agreement); provided that (1) Parent receives written notice from the Company confirming that the Company Board has determined to change its recommendation at least four (4) Business Days in advance of the Company Board Adverse Recommendation Change (the "Notice Period"), which notice shall include a description in reasonable detail of the reasons for such Company Board Adverse Recommendation Change, and written copies of any relevant proposed transaction agreements with any party making a potential Superior Offer, (2) during any Notice Period, Parent shall be entitled to deliver to the Company one or more counterproposals to such Acquisition Proposal and the Company will, and cause its Representatives to, negotiate with Parent in good faith (to the extent Parent desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that the applicable Acquisition Proposal ceases to constitute a Superior Offer and (3) in the event of any material amendment to any Superior Offer (including any revision in the amount, form or mix of consideration the Company's stockholders would receive as a result of such potential Superior Offer), the Company shall be required to provide Parent with notice of such material amendment and the Notice Period shall be extended, if applicable, to ensure that at least three (3) Business Days remain in the Notice Period following such notification during which the parties shall comply again with the requirements of this Section 6.2(d) and the Company Board shall not make a Company Board Adverse Recommendation Change prior to the end of such Notice Period as so extended (it being understood that there may be multiple extensions) or (y) in the case of a Company Intervening Event, the Company promptly notifies Parent, in

73

writing, within the Notice Period before making a Company Board Adverse Recommendation Change, which notice shall state expressly the material facts and circumstances related to the applicable Company Intervening Event and that the Company Board intends to make a Company Board Adverse Recommendation Change, and the Company shall have given Parent two (2) Business Days thereafter to propose revisions to the terms of this Agreement or make other proposals so that such Company Intervening Event would no longer necessitate a Company Board Adverse Recommendation Change.

(e) The Company's obligation to solicit the consent of its stockholders to sign the Company Stockholder Written Consent in accordance with Section 6.2(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer or other Acquisition Proposal or Acquisition Inquiry or Company Intervening Event, or by any Company Board Adverse Recommendation Change.

6.3 Parent Shareholder Meeting.

(a) Parent shall take all action necessary under applicable Law to call, give notice of and hold a meeting of the holders of Parent Common Stock to consider and vote to approve (I) the issuance of shares of Parent Common Stock that represent (or are convertible into) more than twenty percent (20%) of the shares of Parent Common Stock outstanding immediately prior to the First Effective Time to the Company stockholders in connection with the Contemplated Transactions and the change of control of Parent resulting from the Contemplated Transactions, in each case pursuant to the Nasdaq rules and (II) clauses (ii) through (vi) of the definition of "Parent Articles of Amendment" (collectively, the "Parent Shareholder Matters" and such meeting, the "Parent Shareholder Meeting"). The Parent Shareholder Meeting shall be held as promptly as practicable after the date that the Registration Statement is declared effective under the Securities Act, and in any event, no later than forty-five (45) days after the effective date of the Registration Statement.

Notwithstanding anything to the contrary contained herein, if on the date of the Parent Shareholder Meeting, or a date preceding the date on which the Parent Shareholder Meeting is scheduled, Parent reasonably believes that (i) it will not receive proxies sufficient to obtain the Required Parent Shareholder Vote, whether or not a quorum would be present, (ii) it will not have sufficient shares of Parent Common Stock represented (whether in person or by proxy) to constitute a quorum necessary to conduct the business of the Parent Shareholder Meeting or (iii) that the failure to postpone or adjourn the Parent Shareholder Meeting would reasonably be expected to be inconsistent with its fiduciary obligations under applicable Law, Parent may postpone or adjourn, or make one or more successive postponements or adjournments of, the Parent Shareholder Meeting as long as the date of the Parent Shareholder Meeting is not postponed or adjourned more than an aggregate of 45 days in connection with any postponements or adjournments.

74

Parent Board determines, following consultation with its outside legal counsel and financial advisor, to be a Superior Offer or (ii) as a result of a material development or change in circumstances (other than any such event, development or change to the extent related to (A) any Acquisition Proposal, Acquisition Inquiry, Acquisition Transaction or the consequences thereof, (B) the fact, in and of itself, that Parent meets or exceeds internal budgets, plans or forecasts of its revenues, earnings or other financial performance or results of operations, or (C) any Parent Legacy Transaction) that affects the business, assets or operations of Parent that occurs or arises after the date of this Agreement (a "Parent Intervening Event"), if, but only if, (x) in the case of a Superior Offer, following the receipt of and on account of such Superior Offer, (i) the Parent Board determines in good faith, based on the advice of its outside legal counsel, that the failure to withhold, amend, withdraw or modify the Parent Board Recommendation would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law, (ii) Parent has, and has caused its financial advisors and outside legal counsel to, during the Parent Notice Period (as defined below), negotiated with the Company in good faith to make such adjustments to the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Offer, and (iii) if, after the Company has delivered to Parent a written offer to alter the terms or conditions of this Agreement during the Parent Notice Period, the Parent Board shall have determined in good faith, based on the advice of its outside legal counsel and financial advisor, that the failure to withhold, amend, withdraw or modify the Parent Board Recommendation would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law (after taking into account such alterations of the terms and conditions of this Agreement); provided that (1) the Company receives written notice from Parent confirming that the Parent Board has determined to change its recommendation at least four (4) Business Days in advance of the Parent Board Adverse Recommendation Change (the "Parent Notice Period"), which notice shall include a description in reasonable detail of the reasons for such Parent Board Adverse Recommendation Change, and written copies of any relevant proposed transaction agreements with any party making a potential Superior Offer, (2) during any Parent Notice Period, the Company shall be entitled to deliver to Parent one or more counterproposals to such Acquisition Proposal and Parent will, and cause its Representatives to, negotiate with the Company in good faith (to the extent the Company desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that the applicable Acquisition Proposal ceases to constitute a Superior Offer and (3) in the event of any material amendment to any Superior Offer (including any revision in the amount, form or mix of consideration the Parent's shareholders would receive as a result of such potential Superior Offer), Parent shall be required to provide the Company with notice of such material amendment and the Parent Notice Period shall be extended, if applicable, to ensure that at least three (3) Business Days remain in the Parent Notice Period following such notification during which the parties shall comply again with the requirements of this Section 6.3(c) and the Parent Board shall not make a Parent Board Adverse Recommendation Change prior to the end of such Parent Notice Period as so extended (it being understood that there may be multiple extensions) or (y) in the case of a Parent Intervening Event, Parent promptly notifies the Company, in writing, within the Parent Notice Period before making a Parent Board Adverse Recommendation Change, which notice shall state expressly the material facts and circumstances related to the applicable Parent Intervening Event and that the Parent Board intends to make a Parent Board Adverse Recommendation Change.

(d) Parent's obligation to call, give notice of and hold the Parent Shareholder Meeting in accordance with Section 6.3(a) shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission of any Superior Offer, Acquisition Proposal or Acquisition Inquiry, or by any Parent Board Adverse Recommendation Change.

(e) Nothing contained in this Agreement shall prohibit Parent or the Parent Board from (i) complying with Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided, however, that any disclosure made by Parent or the Parent Board pursuant to Rules 14d-9 and 14e-2(a) shall be limited to a statement that Parent is unable to take a position with respect to the bidder's tender offer unless the Parent Board determines in good faith, after consultation with its outside legal counsel, that such

75

statement would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law; (ii) complying with Item 1012(a) of Regulation M-A promulgated under the Exchange Act; (iii) informing any Person of the existence of the provisions contained in Section 5.4; or (iv) making any disclosure that the Parent Board (or a committee thereof), after consultation with its outside legal counsel, has determined in good faith is required by applicable Law or by any listing or trading rules or regulations of Nasdaq; provided that, in the case of (iv), Parent shall provide the Company with a reasonable opportunity to review any such disclosure not less than two (2) Business Days prior to the making thereof (to the extent practicable) and shall consider in good faith any comments from the Company thereto.

6.4 Efforts; Regulatory Approvals.

(a) The Parties shall use commercially reasonable efforts to obtain all regulatory approvals required by applicable Law to consummate the Contemplated Transactions.

Parent and the Company shall each pay 50% of all filing fees required to be paid by the Parties in connection with any notification and report forms required to be filed under the HSR Act or any notification or other document required to be filed in connection with the Merger under any applicable foreign Law relating to antitrust or competition matters (collectively, "Antitrust Fees").

(a) At the First Effective Time, Parent shall assume each Company Stock Plan and each Company Option (including any Service Provider Grants), whether vested or unvested, that is outstanding immediately prior to the First Effective Time shall, at the First Effective Time, cease to represent a right to acquire shares of Company Common Stock and shall be converted, at the First Effective Time, into an option to purchase shares of Parent Common Stock (an "Assumed Option"), on the same terms and conditions (including any vesting provisions and any provisions providing for accelerated vesting upon certain events) as were applicable under such Company Option as of immediately prior to the First Effective Time, except for administrative or ministerial changes as determined by the Company Board (or, following the First Effective Time, the Parent Board or compensation committee). The number of shares of Parent Common Stock subject to each such Assumed Option shall be equal to (i) the number of shares of Company Common Stock subject to the respective Company Option immediately prior to the First Effective Time multiplied by (ii) the Exchange Ratio, rounded down, if necessary, to the nearest whole share of Parent Common Stock, and such Assumed Option shall have an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of the Company Common Stock otherwise purchasable pursuant to the respective Company Option immediately prior to the First Effective Time divided by (B) the Exchange Ratio; provided that in the case of any Company Option to which Section 421 of the Code applies as of immediately prior to the First Effective Time (taking into account the effect of any accelerated vesting thereof, if applicable) by reason of its qualification under Section 422 of the Code, the exercise price, the number of shares of Parent Common Stock subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 424(a) of the Code; provided further, that in the case of any Assumed Option to which Section 409A of the Code applies as of the First Effective Time, the exercise price, the number of shares of Parent Common Stock subject to such option and the terms and conditions of exercise of such option shall be determined in a manner consistent with the requirements of Section 409A of the Code in order to avoid the imposition of any additional taxes thereunder. The Company Board shall, prior to the First Effective Time, take all actions necessary to effect the foregoing.

(b) At the First Effective Time, each award of Company RSU (including any Service Provider Grants), whether vested or unvested, that is outstanding immediately prior to the First Effective Time shall, at the First Effective Time, cease to represent a right to acquire shares of Company Common Stock and shall be converted, at the First Effective Time, into a restricted stock unit award to acquire shares of Parent Common Stock (an "Assumed RSU Award"), on the same terms and conditions (including any vesting provisions and any provisions providing for accelerated vesting upon certain events) as were applicable under such Company RSU as of immediately prior to the First Effective Time, except for administrative or ministerial changes as determined by the Company Board (or, following the First Effective Time, the Parent Board or compensation committee). Each such Assumed RSU Award shall represent the right to receive, upon settlement, that number of shares of Parent Common Stock as is equal to: (i) the number of shares of Company Common Stock subject to the respective Company RSU immediately prior to the First Effective Time multiplied by (ii) the Exchange Ratio, rounded down, if necessary, to the nearest whole share of Parent Common Stock; provided, that in the case of any Assumed RSU Award to which Section 409A of the Code applies as of the First Effective Time, the number of shares of Parent Common Stock subject to such restricted stock unit and the terms and conditions governing such restricted stock unit shall be determined in a manner consistent with the requirements of Section 409A of the Code in order to avoid the imposition of any additional taxes thereunder. The Company Board shall, prior to the First Effective Time, take all actions necessary to effect the foregoing.

77

(c) At the First Effective Time, each Company Warrant (including any pre-funded Company Warrant issued pursuant to the Company Pre-Closing Financing), whether vested or unvested, that is outstanding immediately prior to the First Effective Time shall, at the First Effective Time, cease to represent a right to acquire shares of Company Capital Stock and shall be converted, at the First Effective Time, into a warrant to purchase shares of Parent Common Stock (an "Assumed Warrant"), on the same terms and conditions (including any vesting provisions and any provisions providing for accelerated vesting upon certain events) as were applicable under such Assumed Warrant as of immediately prior to the First Effective Time. The number of shares of Parent Common Stock subject to each such Assumed Warrant shall be equal to (i) the number of shares of the Company Common Stock subject to each Assumed Warrant immediately prior to the First Effective Time multiplied by (ii) the Exchange Ratio (rounded up to the next whole share of Parent Common Stock to the extent the aggregate amount of fractional shares of Parent Common Stock such holder of Assumed Warrants would otherwise be entitled to is equal to or exceeds 0.50, and otherwise rounded down), and such Assumed Warrant shall have an exercise price per share (rounded up to the nearest whole cent) equal to (A) the exercise price per share of the Company Common Stock otherwise purchasable pursuant to such Assumed Warrant immediately prior to the First Effective Time divided by (B) the Exchange Ratio. The Company Board shall, prior to the First Effective Time, take all actions necessary to effect the foregoing.

6.6 Employee Benefits.

(a) Parent shall comply with the terms of any employment, severance, retention, change of control, or similar agreement specified on Section 4.17(d) or contemplated by Section 5.1(b) of the Parent Disclosure Letter, subject to the provisions of such agreements. The parties acknowledge and agree that the Merger shall not constitute a "change in control" (or term of similar import) under any Company Employee Plan.

(b) From and after the First Effective Time, with respect to each benefit plan maintained by Parent or the Surviving Entity that is an "employee welfare benefit plan" as defined in Section 3(1) of ERISA (each, a "Post-Closing Welfare Plan") in which any current or former employee of Parent is or becomes eligible to participate (including under COBRA), Parent and the Surviving Entity shall use commercially reasonable efforts to cause each such Post-Closing Welfare Plan to (i) waive all limitations as to pre-existing conditions, waiting periods, required physical examinations and exclusions with respect to participation and coverage requirements applicable under such Post-Closing Welfare Plan for such current or former Parent employee and his or her eligible dependents to the same extent that such pre-existing conditions, waiting periods, required physical examinations and exclusions would not have applied or would have been waived under the corresponding Parent Employee Plan in which such current or former Parent employee was a participant immediately prior to his or her commencement of participation in such Post-Closing Welfare Plan, and (ii) provide each such current or former Parent employee and his or her eligible dependents with credit for any co-payments and deductibles paid in the plan year that includes the First Effective Time, and prior to the date that, such current or former Parent employee commences participation in such Post-Closing Welfare Plan in satisfying any applicable co-payment or deductible requirements under such Post-Closing Welfare Plan for the applicable plan year, to the extent that such expenses were recognized for such purposes under the comparable Parent Employee Plan.

(c) Parent 401(k) Plan. Unless directed otherwise by the Company in writing no less than three (3) Business Days before the Closing Date, Parent shall have, at least one (1) Business Day prior to the Closing Date, (i) ceased contributions to, and adopted written resolutions (or taken other necessary and appropriate action(s)) to terminate any Parent Employee Plan that is intended to qualify under Section 401(a) of the Code with a cash or deferred arrangement described in Section 401(k) of the Code (collectively, the "401(k) Plans") in compliance with such 401(k) Plan's terms and the requirements of applicable Law, (ii) made all employee and employer contributions to the 401(k) Plans for all periods of

78

service prior to the Closing Date, including such contributions that would have been made on behalf of 401(k) Plan participants had the Merger not occurred (regardless of any service or end-of-year employment requirements) but prorated for the portion of the plan year that ends on the Closing Date, and (iii) 100% vested all participants under the 401(k) Plans, with such termination, contributions and vesting effective no later than one (1) day prior to the Closing Date. Parent shall provide the Company copies of all such corporate actions or documentation related to the same at least three (3) Business Days before their adoption or approval for the Company's reasonable review and comment.

(d) Parent Options. As of immediately prior to the First Effective Time, each Parent Option that is then outstanding but not then vested or exercisable shall become immediately vested (with all performance conditions associated with such Parent Options, if any, deemed satisfied in full) and exercisable in full. At the First Effective Time, each In the Money Parent Option that is then outstanding shall be canceled and the holder thereof shall be entitled to receive (i) an amount in cash without interest, less any applicable tax withholding, equal to the product obtained by multiplying (A) the excess of the Parent Closing Price over the exercise price per share of the Parent Common Stock underlying such Parent Option by (B) the number of shares of the Parent Common Stock underlying such Parent Option (such amount, the "Parent Stock Option Cash Consideration"). Parent shall cause the Surviving Entity to pay the Parent Stock Option Cash Consideration, less applicable withholdings, at or within ten (10) Business Days after the First Effective Time. At the First Effective Time, each Out of the Money Parent Option shall be cancelled for no consideration. Prior to the Closing, the Parent Board shall have adopted appropriate resolutions and taken all other actions necessary and appropriate to provide for the foregoing.

(e) Parent Restricted Stock Awards. As of immediately prior to the First Effective Time, the Parent Board shall have adopted appropriate resolutions and taken all other actions necessary and appropriate to provide that the vesting of each outstanding and unvested Parent Restricted Stock Award shall be accelerated in full effective as of immediately prior to the First Effective Time, contingent on the occurrence of the Closing. Notwithstanding anything herein to the contrary, the tax withholding obligations for each holder receiving shares of Parent Common Stock in accordance with the preceding sentence shall be satisfied by Parent withholding from issuance that number of shares of Parent Common Stock calculated by multiplying the legally-required withholding rate for such holder in connection with such issuance by the number of shares of Parent Common Stock to be issued in accordance with the preceding sentence, and rounding up to the nearest whole share and remitting such withholding in cash to the appropriate taxing authorities. Prior to the Closing, the Parent Board shall have adopted appropriate resolutions and taken all other actions necessary and appropriate to provide for the foregoing.

6.7 Indemnification of Officers and Directors.

(a) From the First Effective Time through the sixth anniversary of the date on which the First Effective Time occurs, each of Parent and the Surviving Entity shall indemnify and hold harmless each person who is now, or has been at any time prior to the date hereof, or who becomes prior to the First Effective Time, a director or officer of Parent or the Company, respectively (the "D&O Indemnified Parties"), against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys' fees and disbursements (collectively, "Costs"), incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that the D&O Indemnified Party is or was a director or officer of Parent or of the Company, whether asserted or claimed prior to, at or after the First Effective Time, in each case, to the fullest extent permitted under the DGCL or the MBCA, as applicable. Each D&O Indemnified Party will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from each of Parent and the Surviving Entity, jointly and severally, upon receipt by Parent or the Surviving Entity from the D&O Indemnified Party of a request therefor; provided that any such person to whom expenses are advanced provides an undertaking to Parent, to the

79

extent then required by the DGCL or the MBCA, as applicable, to repay such advances if it is ultimately determined that such person is not entitled to indemnification.

11.9 Severability.

11.10 Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms (including failing to take such actions as are required of it hereunder to consummate this Agreement) or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity, and each of the Parties waives any bond, surety or other security that might be required of any other Party with respect thereto. Each of the Parties further agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity.

11.11 No Third-Party Beneficiaries. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person (other than the Parties and the D&O Indemnified Parties to the extent of their respective rights pursuant to Section 6.7) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

4.3 Election of Directors.

4.3.1 At all times when at least 30% of the originally issued Series B Non-Voting Preferred Stock remains issued and outstanding, (i) the holders of record of the shares of Series B Non-Voting Preferred Stock, exclusively and voting together as a separate class on an as-converted to Common Stock basis, shall be entitled to elect four directors of the Corporation (the "Preferred Directors"); and (iii) the holders of record of the shares of Common Stock and of any other class or series of voting stock (including the Series B Non-Voting Preferred Stock), exclusively and voting together as a single class on an as-converted to Common Stock basis, shall be entitled to elect the balance of the total number of directors of the Corporation (the "At-Large Directors"); provided, however, for administrative convenience, the initial Preferred Directors may also be appointed by the Board of Directors in connection with the approval of the initial issuance of Series B Non-Voting Preferred Stock without a separate action by the holders of Series B Non-Voting Preferred Stock.

4.3.2 Any Preferred Director elected as provided in Section 4.3.1 may be removed without cause by, and only by, the affirmative vote of the holders of a majority of the shares of the Series B Non-Voting Preferred Stock, given either at a special meeting of such stockholders duly called for that purpose or pursuant to a written consent of stockholders.

4.3.3 If the holders of shares of the Series B Non-Voting Preferred Stock fail to elect a sufficient number of directors to fill all directorships for which they are entitled to elect directors pursuant to Section 4.3.1 (and to the extent any of such directorships is not otherwise filled by a director appointed in accordance with the proviso in Section 4.3.1), then any directorship not so filled shall remain vacant until such time as the holders of the Series B Non-Voting Preferred Stock fill such directorship in accordance with Section 4.3.1.

3

5.2 Upon any liquidation, dissolution or winding-up of the Corporation, whether voluntary or involuntary (a "Liquidation"), each Holder shall be entitled to receive out of the assets, whether capital or surplus, of the Corporation the same amount that a holder of Common Stock would receive if the Series B Non-Voting Preferred Stock were fully converted (disregarding for such purpose any Beneficial Ownership Limitations) to Common Stock which amounts shall be paid pari passu with all holders of Common Stock, plus an additional amount equal to any dividends declared on but unpaid to such shares. If, upon any such Liquidation, the assets of the Corporation shall be insufficient to pay the Holders of shares of the Series B Non-Voting Preferred Stock the amount required under the preceding sentence, then all remaining assets of the Corporation shall be distributed ratably to the Holders and the holders of Common Stock in accordance with the respective amounts that would be payable on all such securities if all amounts payable thereon were paid in full. For the avoidance of any doubt, a Fundamental Transaction shall not be deemed a Liquidation unless the Corporation expressly declares that such Fundamental Transaction shall be treated as if it were a Liquidation.

6. Conversion.

6.1 Reserved.

6.2 Conversion at Option of Holder. Subject to Section 6.4 and Section 6.5.3, each share of Series B Non-Voting Preferred Stock then outstanding shall be convertible, at any time and from time to time, at the option of the Holder thereof, into a number of shares of Common Stock equal to the Conversion Ratio, subject to the Beneficial Ownership Limitation (each, an "Optional Conversion"). Holders shall effect conversions by providing the Corporation with the form of conversion notice attached hereto as Annex A (a "Notice of Conversion"), duly completed and executed. Provided the Corporation's transfer agent is participating in the Depository Trust Company ("DTC") Fast Automated Securities Transfer program, the Notice of Conversion may specify, at the Holder's election, whether the applicable Conversion Shares shall be credited to the account of the Holder's prime broker with DTC through its Deposit Withdrawal Agent Commission system (a "DWAC Delivery"). The date on which an Optional Conversion shall be deemed effective (the "Conversion Date") shall be the Trading Day that the Notice of Conversion, completed and executed, is sent via email to, and received during regular business hours by, the Corporation; provided, that the original certificate(s) (if any) representing such shares of Series B Non-Voting Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion, are received by the Corporation within two (2) Trading Days thereafter. In all other cases, the Conversion Date shall be defined as the Trading Day on which the original certificate(s) (if any) representing such shares of Series B Non-Voting Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion, are received by the Corporation. The calculations set forth in the Notice of Conversion shall control in the absence of manifest or mathematical error.

6.3 Conversion Ratio. The "Conversion Ratio" for each share of Series B Non-Voting Preferred Stock shall be 1,000 shares of Common Stock issuable upon the conversion (the "Conversion") of each share of Series B Non-Voting Preferred Stock (corresponding to a ratio of 1,000:1), subject to adjustment as provided herein.

6.4 Beneficial Ownership Limitation. Notwithstanding anything herein to the contrary, the Corporation shall not effect any conversion of any share of Series B Non-Voting Preferred Stock, and a Holder shall not have the right to convert any portion of the Series B Non-Voting Preferred Stock pursuant to Section 6.2, to the extent that, after giving effect to such attempted conversion set forth on an applicable Notice of Conversion (as defined in this Description of Rights) with respect to the Series B Preferred Stock, such Holder (or any of such Holder's Affiliates or any other Person who would be a beneficial owner of Common Stock beneficially owned by the Holder for purposes of Section 13(d) or Section 16 of the Exchange Act and the applicable rules and regulations of the Commission, including any "group" of which the Holder is a member (the foregoing, "Attribution Parties")) would beneficially own a number of shares of Common Stock in excess of the Beneficial Ownership Limitation. For purposes of the foregoing sentence, the aggregate number of shares of Common Stock beneficially owned by

such Holder and its Attribution Parties shall include the number of shares of Common Stock issuable upon conversion of the Series B Non-Voting Preferred Stock subject to the Notice of Conversion, with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (A) conversion of the remaining, unconverted Series B Non-Voting Preferred Stock beneficially owned by such Holder or any of its Attribution Parties, and (B) exercise or conversion of the unexercised or unconverted portion of any other securities of the Corporation (including any warrants) beneficially owned by such Holder or any of its Attribution Parties that are subject to and would exceed a limitation on conversion or exercise similar to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this Section 6.4, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the applicable rules and regulations of the Commission, and the terms "beneficial ownership" and "beneficially own" have the meanings ascribed to such terms therein. In addition, for purposes hereof, "group" has the meaning set forth in Section 13(d) of the Exchange Act and the applicable rules and regulations of the Commission. For purposes of this Section 6.4, in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following: (A) the Corporation's most recent periodic or annual filing with the Commission, as the case may be, (B) a more recent public announcement by the Corporation that is filed with the Commission, or (C) a more recent notice by the Corporation or the Corporation's transfer agent to the Holder setting forth the number of shares of Common Stock then outstanding. Upon the written request of a Holder (which may be by email), the Corporation shall, within two (2) Trading Days thereof, confirm in writing to such Holder (which may be via email) the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to any actual conversion or exercise of securities of the Corporation, including shares of Series B Non-Voting Preferred Stock, by such Holder or its Attribution Parties since the date as of which such number of outstanding shares of Common Stock was last publicly reported or confirmed to the Holder. The "Beneficial Ownership Limitation" shall initially be set at the discretion of each Holder to a percentage designated by such Holder on its signature page to the Purchase Agreement or otherwise between 0% and 19.99% of the number of shares of the Common Stock outstanding or deemed to be outstanding as of the applicable measurement date, and such percentage shall be set at 19.99% for any Holder that does not make such designation in the Purchase Agreement or otherwise. The Corporation shall be entitled to rely on representations made to it by the Holder in any Notice of Conversion regarding its Beneficial Ownership Limitation. Notwithstanding the foregoing, by written notice to the Corporation (email being sufficient), (i) the Holder may reset the Beneficial Ownership Limitation percentage to a higher percentage, not to exceed 19.99%, which increase will not be effective until the sixty-first (61st) day after such written notice is delivered to the Corporation, and (ii) the Holder may reset the Beneficial Ownership Limitation percentage to a lower percentage. Upon such a change by a Holder of the Beneficial Ownership Limitation, not to exceed 19.99%, the Beneficial Ownership Limitation may not be further amended by such Holder without first providing the minimum notice required by this Section 6.4. Notwithstanding the foregoing, (x) at any time following notice of a Fundamental Transaction, the Holder may waive and/or change the Beneficial Ownership Limitation effective immediately upon written notice to the Corporation and may reinstitute a Beneficial Ownership Limitation at any time thereafter effective immediately upon written notice to the Corporation and (y) at any time that the beneficial ownership of shares of Common Stock of a Holder (together with any of such Holder's Attribution Parties) is equal to or less than 9.00% of the number of shares of Common Stock outstanding as of any given date, then such Holder's Beneficial Ownership Limitation shall automatically be set to 9.99%. The provisions of this Section 6.4 shall be construed, corrected and implemented in a manner so as to effectuate the intended Beneficial Ownership Limitation herein contained and the shares of Common Stock underlying the Securities in excess of the Beneficial Ownership Limitation shall not be deemed to be beneficially owned by the Purchaser for any purpose including for purposes of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act.

6.5 Mechanics of Conversion.

6.5.1 Delivery of Certificate or Electronic Issuance. Upon Conversion not later than two (2) Trading Days after the applicable Conversion Date, or if the Holder requests the issuance of physical certificate(s), two (2) Trading Days after receipt by the Corporation of the original certificate(s) representing such shares of Series B Non-Voting Preferred Stock being converted, duly endorsed, and the accompanying Notice of Conversion (the "Share Delivery Date"), the Corporation shall either: (a) deliver, or cause to be delivered, to the converting Holder a physical certificate or certificates representing the number of Conversion Shares being acquired upon the conversion of shares of Series B Non-Voting Preferred Stock, or (b) in the case of a DWAC Delivery (if so requested by the Holder), electronically transfer such Conversion Shares by crediting the account of the Holder's prime broker with DTC through its DWAC system. If in the case of any Notice of Conversion such certificate or certificates for the Conversion Shares are not delivered to or as directed by or, in the case of a DWAC Delivery, such shares are not electronically delivered to or as directed by, the applicable Holder by the Share Delivery Date, the applicable Holder shall be entitled to elect to rescind such Notice of Conversion by written notice to the Corporation at any time on or before its receipt of such certificate or certificates for Conversion Shares or electronic receipt of such shares, as applicable, in which event the Corporation shall promptly return to such Holder any original Series B Non-Voting Preferred Stock certificate delivered to the Corporation and such Holder shall promptly return to the Corporation any Common Stock certificates or otherwise direct the return of any shares of Common Stock delivered to the Holder through the DWAC system, representing the shares of Series B Non-Voting Preferred Stock unsuccessfully tendered for conversion to the Corporation.

6.5.2 Obligation Absolute. Subject to Section 6.4 and subject to Holder's right to rescind a Notice of Conversion pursuant to Section 6.5.1, the Corporation's obligation to issue and deliver the Conversion Shares upon conversion of Series B Non-Voting Preferred Stock in accordance with the terms hereof are absolute and unconditional, irrespective of any action or inaction by a Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by such Holder or any other Person of any obligation to the Corporation or any violation or alleged violation of law by such Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such obligation of the Corporation to such Holder in connection with the issuance of such Conversion Shares. Subject to Section 6.4 and subject to Holder's right to rescind a Notice of Conversion pursuant to Section 6.5.1, in the event a Holder shall elect to convert any or all of its Series B Non-Voting Preferred Stock, the Corporation may not refuse conversion based on any claim that such Holder or anyone associated or affiliated with such Holder has been engaged in any violation of law, agreement or for any other reason, unless an injunction from a court, on notice to Holder, restraining and/or enjoining conversion of all or part of the Series B Non-Voting Preferred Stock of such Holder shall have been sought and obtained by the Corporation, and the Corporation posts a surety bond for the benefit of such Holder in the amount of 150% of the value of the Conversion Shares into which would be converted the Series B Non-Voting Preferred Stock which is subject to such injunction, which bond shall remain in effect until the completion of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to such Holder to the extent it obtains judgment. In the absence of such injunction, the Corporation shall, subject to Section 6.4 and subject to Holder's right to rescind a Notice of Conversion pursuant to Section 6.5.1, issue Conversion Shares upon a properly noticed conversion.

6.5.3 Cash Settlement. If, at any time after the the initial issuance of the Series B Non-Voting Preferred Stock, the Corporation fails to deliver to a Holder such certificate or certificates, or electronically deliver (or instruct its transfer agent to electronically deliver) such shares in the case of a DWAC Delivery, pursuant to Section 6.5.1 on or prior to the third (3rd) Trading Day after the Share Delivery Date applicable to such conversion (other than a failure caused by (i) materially incorrect or incomplete information provided by Holder to the Corporation or (ii) the application of the Beneficial Ownership Limitation, then, unless the Holder has rescinded the applicable Notice of Conversion pursuant to Section 6.5.1, the Corporation shall, at the request of the Holder, pay an amount equal to the Fair Value (as defined below) of such undelivered shares, with such payment to be made within two Business Days from the date of request by the Holder, whereupon the Corporation's obligations to deliver such shares underlying the Notice of Conversion shall be extinguished upon payment in full of the Fair Value of such undelivered shares. For purposes of this Section 6.5.3, the "Fair Value" of shares shall be fixed with reference to the last reported Closing Sale Price on the principal Trading Market on which the Common Stock is listed as of the Trading Day immediately prior to the date on which the Notice of Conversion is delivered

6

to the Corporation. For the avoidance of doubt, the cash settlement provisions set forth in this Section 6.5.3 shall be available irrespective of the reason for the Corporation's failure to timely deliver Conversion Shares (other than a failure caused by (i) materially incorrect or incomplete information provided by Holder to the Corporation or (ii) the application of the Beneficial Ownership Limitation, including due to limitations set forth in Section 6.5.6, due to applicable Trading Market rules.

6.5.4 Buy-In on Failure to Timely Deliver Certificates. If the Corporation fails to deliver to a Holder the applicable certificate or certificates or to effect a DWAC Delivery, as applicable, by the Share Delivery Date pursuant to Section 6.5.1 (other than a failure caused by materially incorrect or incomplete information provided by Holder to the Corporation or the application of the Beneficial Ownership Limitation), and if after such Share Delivery Date such Holder is required by its brokerage firm to purchase (in an open market transaction or otherwise), or the Holder's brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by such Holder of the Conversion Shares which such Holder was entitled to receive upon the conversion relating to such Share Delivery Date (a "Buy-In"), then the Corporation shall (A) pay in cash to such Holder (in addition to any other remedies available to or elected by such Holder) the amount by which (x) such Holder's total purchase price (including any brokerage commissions) for the shares of Common Stock so purchased exceeds (y) the product of (1) the aggregate number of shares of Common Stock that such Holder was entitled to receive from the conversion at issue multiplied by (2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage commissions) and (B) at the option of such Holder, either reissue (if surrendered) the shares of Series B Non-Voting Preferred Stock equal to the number of shares of Series B Non-Voting Preferred Stock submitted for conversion or deliver to such Holder the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6.5.1. For example, if a Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Series B Non-Voting Preferred Stock with respect to which the actual sale price (including any brokerage commissions) giving rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Corporation shall be required to pay such Holder $1,000. The Holder shall provide the Corporation written notice, within three (3) Trading Days after the occurrence of a Buy-In, indicating the amounts payable to such Holder in respect of such Buy-In together with applicable confirmations and other evidence reasonably requested by the Corporation. Nothing herein shall limit a Holder's right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Corporation's failure to timely deliver certificates representing shares of Common Stock upon conversion of the shares of Series B Non-Voting Preferred Stock as required pursuant to the terms hereof or the cash settlement remedy set forth in Section 6.5.3; provided, however, that the Holder shall not be entitled to both (i) require the reissuance of the shares of Series B Non-Voting Preferred Stock submitted for conversion for which such conversion was not timely honored and (ii) receive the number of shares of Common Stock that would have been issued if the Corporation had timely complied with its delivery requirements under Section 6.5.1.

6.5.5 Reservation of Shares Issuable Upon Conversion. The Corporation covenants that at all times it will reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series B Non-Voting Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holders of the Series B Non-Voting Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable (taking into account the adjustments of Section 7) upon the conversion of all outstanding shares of Series B Non-Voting Preferred Stock. The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and non-assessable.

6.5.6 Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Series B Non-Voting Preferred Stock, no certificates or scrip for any such fractional shares shall be issued and no cash shall be paid for any such fractional shares. Any fractional shares of Common Stock that a Holder of Series B Non-Voting Preferred Stock would otherwise be entitled to receive shall be aggregated

7

with all fractional shares of Common Stock issuable to such Holder and any remaining fractional shares shall be rounded up to the nearest whole share. Whether or not fractional shares would be issuable upon such conversion shall be determined on the basis of the total number of shares of Series B Non-Voting Preferred Stock the Holder seeks to convert into Common Stock and the aggregate number of shares of Common Stock issuable upon such conversion.

6.5.7 Transfer Taxes. The issuance of certificates for shares of the Common Stock upon conversion of the Series B Non-Voting Preferred Stock shall be made without charge to any Holder for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificates, provided that the Corporation shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the registered Holder(s) of such shares of Series B Non-Voting Preferred Stock and the Corporation shall not be required to issue or deliver such certificates unless or until the Person or Persons requesting the issuance thereof shall have paid to the Corporation the amount of such tax or shall have established to the satisfaction of the Corporation that such tax has been paid.

6.6 Status as Stockholder. Upon each Conversion Date, (i) the shares of Series B Non-Voting Preferred Stock being converted shall be deemed converted into shares of Common Stock and (ii) the Holder's rights as a holder of such converted shares of Series B Non-Voting Preferred Stock shall cease and terminate, excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Corporation to comply with the terms of this Description of Rights. In all cases, the Holder shall retain all of its rights and remedies for the Corporation's failure to convert Series B Non-Voting Preferred Stock.

7. Certain Adjustments.

7.1 Stock Dividends and Stock Splits. If the Corporation, at any time while this Series B Non-Voting Preferred Stock is outstanding: (A) pays a stock dividend or otherwise makes a distribution or distributions payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Corporation upon conversion of this Series B Non-Voting Preferred Stock) with respect to the then outstanding shares of Common Stock; (B) subdivides outstanding shares of Common Stock into a larger number of shares; or (C) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number of shares, then the Conversion Ratio shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding any treasury shares of the Corporation) outstanding immediately after such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately before such event (excluding any treasury shares of the Corporation). Any adjustment made pursuant to this Section 7.1 shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision or combination.

7.2 Fundamental Transaction. If, at any time while this Series B Non-Voting Preferred Stock is outstanding, (A) the Corporation effects any merger or consolidation of the Corporation with or into another Person or any stock sale to, or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, share exchange or scheme of arrangement) with or into another Person (other than such a transaction in which the Corporation is the surviving or continuing entity and its Common Stock is not exchanged for or converted into other securities, cash or property), (B) the Corporation effects any sale, lease, transfer or exclusive license of all or substantially all of its assets in one transaction or a series of related transactions, (C) any tender offer or exchange offer by the Corporation is completed pursuant to which more than 50% of the Common Stock not held by the Corporation is exchanged for or converted into other securities, cash or property, or (D) the Corporation effects any reclassification of the Common Stock or any compulsory share exchange pursuant (other than as a result of a dividend, subdivision or combination covered by Section 7.1) to which the Common Stock is

8

effectively converted into or exchanged for other securities, cash or property (in any such case, a "Fundamental Transaction"), then, upon any subsequent conversion of this Series B Non-Voting Preferred Stock the Holders shall have the right to receive, in lieu of the right to receive Conversion Shares, for each Conversion Share that would have been issuable upon such conversion immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of one share of Common Stock (the "Alternate Consideration"). For purposes of any such subsequent conversion, the determination of the Conversion Ratio shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Corporation shall adjust the Conversion Ratio in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holders shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Series B Non-Voting Preferred Stock following such Fundamental Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Corporation or surviving entity in such Fundamental Transaction shall file a new description of terms, certificate of designations or similar with the same terms and conditions and issue to the Holders new preferred stock consistent with the foregoing provisions and evidencing the Holders' right to convert such preferred stock into Alternate Consideration. The terms of any agreement to which the Corporation is a party and pursuant to which a Fundamental Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of this Section 7.2 and ensuring that this Series B Non-Voting Preferred Stock (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction. The Corporation shall cause to be delivered to each Holder, at its last address as it shall appear upon the stock books of the Corporation, written notice of any Fundamental Transaction at least 20 calendar days prior to the date on which such Fundamental Transaction is expected to become effective or close.

7.3 Calculations. All calculations under this Section 7 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 7, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Corporation) issued and outstanding.

8. Redemption. The shares of Series B Non-Voting Preferred Stock shall not be redeemable; provided, however, that the foregoing shall not limit the ability of the Corporation to purchase or otherwise deal in such shares to the extent otherwise permitted hereby and by law, nor shall the foregoing limit the Holder's rights under Section 6.5.3.

9. Transfer. A Holder may transfer any shares of Series B Non-Voting Preferred Stock together with the accompanying rights set forth herein, held by such Holder without the consent of the Corporation; provided that such transfer is in compliance with applicable securities laws. The Corporation shall in good faith (i) do and perform, or cause to be done and performed, all such further acts and things, and (ii) execute and deliver all such other agreements, certificates, instruments and documents, in each case, as any holder of Series B Non-Voting Preferred Stock may reasonably request in order to carry out the intent and accomplish the purposes of this Section 9. The transferee of any shares of Series B Non-Voting Preferred Stock shall be subject to the Beneficial Ownership Limitation applicable to the transferor as of the time of such transfer.

10. Series B Non-Voting Preferred Stock Register. The Corporation shall maintain at its principal executive offices (or such other office or agency of the Corporation as it may designate by notice to the Holders in accordance with Section 11), a register for the Series B Non-Voting Preferred Stock, in which the Corporation shall record (i) the name, address, and electronic mail address of each holder in whose name the shares of Series B Non-Voting Preferred Stock have been issued and (ii) the name, address, and electronic mail address of each transferee of any shares of Series B Non-Voting Preferred Stock. The Corporation may deem and treat the registered Holder of shares of Series B Non-Voting Preferred Stock as the absolute owner thereof for the purpose of any conversion thereof and for all other purposes. The Corporation shall keep the register open and available at all times during business hours for inspection by any holder of Series B Non-Voting Preferred Stock or his, her or its legal representatives.

9

11. Notices. Any notice required or permitted by the provisions of this Description of Rights to be given to a Holder of shares of Series B Non-Voting Preferred Stock shall be mailed, postage prepaid, to the post office address last shown on the records of the Corporation, or given by electronic communication in compliance with the provisions of the Mass Law, and shall be deemed sent upon such mailing or electronic transmission.

12. Book-Entry; Certificates. The Series B Non-Voting Preferred Stock will be issued in book-entry form; provided that, if a Holder requests that such Holder's shares of Series B Non-Voting Preferred Stock be issued in certificated form, the Corporation will instead issue a stock certificate to such Holder representing such Holder's shares of Series B Non-Voting Preferred Stock. To the extent that any shares of Series B Non-Voting Preferred Stock are issued in book-entry form, references herein to "certificates" shall instead refer to the book-entry notation relating to such shares.

13. Lost or Mutilated Series B Non-Voting Preferred Stock Certificate. If a Holder's Series B Non-Voting Preferred Stock certificate shall be mutilated, lost, stolen or destroyed, the Corporation shall execute and deliver, in exchange and substitution for and upon cancellation of a mutilated certificate, or in lieu of or in substitution for a lost, stolen or destroyed certificate, a new certificate for the shares of Series B Non-Voting Preferred Stock so mutilated, lost, stolen or destroyed, but only upon receipt of evidence of such loss, theft or destruction of such certificate, and of the ownership hereof reasonably satisfactory to the Corporation.

14. Waiver. Any waiver by the Corporation or a Holder of a breach of any provision of this Description of Rights shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Description of Rights or a waiver by any other Holders. The failure of the Corporation or a Holder to insist upon strict adherence to any term of this Description of Rights on one or more occasions shall not be considered a waiver or deprive that party (or any other Holder) of the right thereafter to insist upon strict adherence to that term or any other term of this Description of Rights. Any waiver by the Corporation or a Holder must be in writing. Notwithstanding any provision in this Description of Rights to the contrary, any provision contained herein and any right of the Holders of Series B Non-Voting Preferred Stock granted hereunder may be waived as to all shares of Series B Non-Voting Preferred Stock (and the Holders thereof) upon the written consent of the Holders of not less than a majority of the shares of Series B Non-Voting Preferred Stock then outstanding, provided, however, that the Beneficial Ownership Limitation applicable to a Holder, and any provisions contained herein that are related to such Beneficial Ownership Limitation, cannot be modified, waived or terminated without the consent of such Holder, provided further, that any proposed waiver that would, by its terms, have a disproportionate and materially adverse effect on any Holder shall require the consent of such Holder(s).

15. Severability. Whenever possible, each provision hereof shall be interpreted in a manner as to be effective and valid under applicable law, but if any provision hereof is held to be prohibited by or invalid under applicable law, then such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating or otherwise adversely affecting the remaining provisions hereof.

10

16. Status of Converted Series B Non-Voting Preferred Stock. If any shares of Series B Non-Voting Preferred Stock shall be converted or redeemed by the Corporation, such shares shall, to the fullest extent permitted by applicable law, be retired and cancelled upon such acquisition, and shall not be reissued as a share of Series B Non-Voting Preferred Stock. Any share of Series B Non-Voting Preferred Stock so acquired shall, upon its retirement and cancellation, and upon the taking of any action required by applicable law, resume the status of authorized but unissued shares of preferred stock and shall no longer be designated as Series B Non-Voting Preferred Stock.

(d) Notwithstanding anything else herein to the contrary, the Stockholder may, at any time, Transfer Shares (i) by will or other testamentary document or by intestacy to the legal representative, heir, beneficiary or a member of the immediate family of the Stockholder or, if the Stockholder is a corporation, partnership or other entity, to an immediate family member of a beneficial owner of the Shares held by the Stockholder, (ii) to such Stockholder's Affiliates (in each case, directly or indirectly), (iii) to any trust or other entity for the direct or indirect benefit of the Stockholder or the immediate family of the Stockholder (or, if the Stockholder is a corporation, partnership or other entity, for the direct or indirect benefit of an immediate family member of a beneficial owner of the Shares held by the Stockholder) or otherwise for estate tax or estate planning purposes, (iv) in the case of a Stockholder who is not a natural person, by pro rata distributions from the Stockholder to its members, partners, or shareholders pursuant to

Page 2

the Stockholder's organizational documents, (v) purchased from the Company pursuant to the Company Pre-Closing Financing on or about the Closing Date (including any shares of the Company issued upon conversion of any pre-funded warrants of Parent), (vi) pursuant to applicable Law or by operation of law pursuant to a qualified domestic relations order or in connection with a divorce settlement and (vii) pursuant to the exercise of any option to purchase any Company Capital Stock or settlement of any restricted stock units, including in order to pay the exercise price of such option or otherwise satisfy taxes applicable thereto; provided, that in the cases of clauses (i)-(vi), (x) such Transferred Shares shall continue to be bound by this Agreement and (y) the applicable direct transferee (if any) of such Transferred Shares shall have executed and delivered to Parent and the Company a support agreement substantially identical to this Agreement upon consummation of the Transfer if not already a party thereto. Any action taken in violation of Section 2(a) through Section 2(d) shall be null and void ab initio.

(e) Notwithstanding anything to the contrary herein, nothing in this Agreement shall obligate the Stockholder to exercise any option or any other right to acquire any shares of Company Capital Stock.

3. Agreement to Vote Shares. The Stockholder covenants to Parent and the Company as follows:

(a) Until the Expiration Date, at every meeting of the stockholders of the Company, however called, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company, the Stockholder shall be present (in person or by proxy) and vote, or exercise its right to consent with respect to, all Shares held by the Stockholder (A) in favor of the adoption and approval of the Merger Agreement, (B) in favor of approval of the Contemplated Transactions, (C) against approval of any proposal made in opposition to, or in competition with, the Merger Agreement or the consummation of the Contemplated Transactions and (D) against any Acquisition Proposal.

(b) If the Stockholder is the beneficial owner, but not the record holder, of Shares, the Stockholder agrees to take all actions necessary to cause the record holder and any nominees to be present (in person or by proxy) and vote all the Stockholder's Shares in accordance with this Section 3.

(c) In the event of a stock split, stock dividend or distribution, or any change in the capital stock of the Company by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, reincorporation, exchange of shares or the like, the term "Shares" shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of such shares may be changed or exchanged or which are received in such transaction.

4. Action in Stockholder Capacity Only. The Stockholder is entering into this Agreement solely in the Stockholder's capacity as a record holder and/or beneficial owner, as applicable, of its Shares and not in the Stockholder's capacity as a director or officer of the Company. Nothing herein shall limit or affect the Stockholder's ability to exercise the Stockholder's fiduciary duties as an officer or director of the Company.

5. Irrevocable Proxy. The Stockholder hereby revokes (or agrees to cause to be revoked) any proxies that the Stockholder has heretofore granted with respect to its Shares. In the event and to the extent that the Stockholder fails to vote the Shares in accordance with Section 3 at any applicable meeting of the stockholders of the Company or pursuant to any applicable written consent of the stockholders of the Company, the Stockholder shall be deemed to have irrevocably granted to, and appointed, Parent, as his, her or its proxy and attorney-in-fact (with full power of substitution), for and in its name, place and stead,

Page 3

to (a) attend any all meetings of the Company stockholders with respect to any of the matters specified in Section 3 and (b) vote, express consent, dissent or grant, withhold or issue instructions to the record holder to vote his, her or its Shares in any action by written consent of Company stockholders or at any meeting of the Company's stockholders called with respect to any of the matters specified in, and in accordance and consistent with, Section 3 of this Agreement. Parent agrees not to exercise the proxy granted herein for any purpose other than the purposes described in this Agreement. Except as otherwise provided for herein (including the next sentence), the Stockholder hereby affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked and that such irrevocable proxy is executed and intended to be irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of the Stockholder, as applicable) and shall not be terminated by operation of law or upon the occurrence of any other event other than the termination of this Agreement pursuant to Section 9. Notwithstanding any other provisions of this Agreement, the irrevocable proxy granted hereunder shall automatically terminate on the Expiration Date. The Stockholder authorizes such attorney and proxy to substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the Secretary of Company. The Stockholder hereby affirms that the proxy set forth in this Section 5 is given in connection with and granted in consideration of and as an inducement to Parent and the Merger Subs to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Stockholder under Section 3. With respect to any Shares that are owned beneficially by the Stockholder but are not held of record by the Stockholder (other than shares beneficially owned by the Stockholder that are held in the name of a bank, broker or nominee), the Stockholder shall take all action necessary to cause the record holder of such Shares to grant the irrevocable proxy and take all other actions provided for in this Section 5 with respect to such Shares.

6. No Solicitation. The Stockholder agrees not to directly or indirectly, including through any of its officers, directors or agents, take any action that the Company is prohibited from taking pursuant to Section 5.4 of the Merger Agreement and Section 5.4 of the Merger Agreement is hereby incorporated by reference mutatis mutandis. The Stockholder hereby represents and warrants that the Stockholder has read Section 5.4 of the Merger Agreement.

7. Documentation and Information. The Stockholder shall permit and hereby authorizes Parent and the Company to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that Parent or the Company reasonably determines to be necessary in connection with the Merger and any of the Contemplated Transactions, a copy of this Agreement, the Stockholder's identity and ownership of the Shares and the nature of the Stockholder's commitments and obligations under this Agreement.

8. No Exercise of Appraisal Rights; Waivers. The Stockholder hereby irrevocably and unconditionally (a) waives, and agrees to cause to be waived and to prevent the exercise of, any rights of appraisal, any dissenters' rights and any similar rights (including any notice requirements related thereto) relating to the Contemplated Transactions that Stockholder may have by virtue of, or with respect to, any Shares under any applicable Law (including all rights under Section 262 of the DGCL, a copy of which is attached hereto as Appendix B) and (b) agrees that the Stockholder will not bring, commence, institute, maintain, prosecute or voluntarily aid or participate in any action, claim, suit or cause of action, in law or in equity, in any court or before any Governmental Authority, which (i) challenges the validity of or seeks to enjoin the operation of any provision of this Agreement or (ii) alleges that (A) the execution and delivery of this Agreement by the Stockholder breaches any duty that such Stockholder has (or may be alleged to have) to the Company or to the other Company stockholders, (B) the approval of the Merger Agreement by the Company Board breaches any fiduciary duty of the Company Board or any member thereof, or (C) the Contemplated Transactions constitute a breach of any fiduciary duty of the Company Board or any member thereof; provided, that (x) the Stockholder may defend against, contest or settle any such action, claim, suit or cause of action brought against the Stockholder that relates solely to the Stockholder's capacity as a

Page 4

director, officer or securityholder of the Company and (y) the foregoing shall not limit or restrict in any manner the Stockholder from enforcing the Stockholder's rights under this Agreement and the other agreements entered into by the Stockholder in connection herewith, or otherwise in connection with the Merger, including the Stockholder's right to receive the Merger Consideration pursuant to the terms of the Merger Agreement.

9. Representations and Warranties of the Stockholder. The Stockholder hereby represents and warrants to Parent and the Company as follows:

(a) (i) The Stockholder is the beneficial owner of the shares of Company Capital Stock indicated in Appendix A (each of which shall be deemed to be "held" by the Stockholder for purposes of Section 3 unless otherwise expressly stated with respect to any shares in Appendix A), free and clear of any and all Encumbrances (except for any Encumbrance that may be imposed pursuant to this Agreement, any lock-up agreement entered into by and between the Stockholder, the Company and Parent, and Encumbrances arising under applicable securities or community property laws); and (ii) the Stockholder does not beneficially own any securities of the Company other than the shares of Company Capital Stock and rights to purchase shares of Company Capital Stock set forth in Appendix A.

(b) Except as otherwise provided in this Agreement, the Stockholder has full power and authority to (i) make, enter into and carry out the terms of this Agreement and (ii) vote all of its Shares in the manner set forth in this Agreement without the consent or approval of, or any other action on the part of, any other person or entity (including any Governmental Authority). Without limiting the generality of the foregoing, the Stockholder has not entered into any voting agreement (other than this Agreement) with any person with respect to any of the Stockholder's Shares, granted any person any proxy (revocable or irrevocable) or power of attorney with respect to any of the Stockholder's Shares, deposited any of the Stockholder's Shares in a voting trust or entered into any arrangement or agreement with any person limiting or affecting the Stockholder's legal power, authority or right to vote the Stockholder's Shares on any matter.

(c) This Agreement has been duly and validly executed and delivered by the Stockholder and (assuming the due authorization, execution and delivery by the other Parties) constitutes a valid and binding agreement of the Stockholder enforceable against the Stockholder in accordance with its terms, subject to the Enforceability Exceptions. The execution and delivery of this Agreement by the Stockholder and the performance by the Stockholder of the agreements and obligations hereunder will not result in any breach or violation of or be in conflict with or constitute a default under any term of any Contract or, if applicable, any provision of an organizational document (including a certificate of incorporation) to or by which the Stockholder is a party or bound, or any applicable law to which the Stockholder (or any of the Stockholder's assets) is subject or bound, except for any such breach, violation, conflict or default which, individually or in the aggregate, would not reasonably be expected to materially impair or adversely affect the Stockholder's ability to perform its obligations under this Agreement.

(d) The execution, delivery and performance of this Agreement by the Stockholder do not and will not require any consent, approval, authorization or permit of, action by, filing with or notification to, any Governmental Authority, except for any such consent, approval, authorization, permit, action, filing or notification the failure of which to make or obtain, individually or in the aggregate, has not and would not materially impair the Stockholder's ability to perform its obligations under this Agreement.

(e) The Stockholder has had the opportunity to review the Merger Agreement and this Agreement with counsel of the Stockholder's own choosing. The Stockholder has had an opportunity to review with its own tax advisors the tax consequences of the Merger and the Contemplated Transactions. The Stockholder understands that it must rely solely on its advisors and not on any statements or

Page 5

representations made by Parent, the Company or any of their respective agents or representatives with respect to the tax consequences of the Merger and the Contemplated Transactions. The Stockholder understands that such Stockholder (and not Parent, the Company or the Surviving Entity) shall be responsible for such Stockholder's tax liability that may arise as a result of the Merger or the Contemplated Transactions. The Stockholder understands and acknowledges that the Company, Parent and the Merger Subs are entering into the Merger Agreement in reliance upon the Stockholder's execution, delivery and performance of this Agreement.

(f) With respect to the Stockholder, as of the date hereof, there is no action, suit, investigation or proceeding pending against, or, to the knowledge of the Stockholder, threatened against, the Stockholder or any of the Stockholder's properties or assets (including the Shares) that would reasonably be expected to prevent or materially delay or impair the ability of the Stockholder to perform its obligations hereunder or to consummate the transactions contemplated hereby.

10. Certain Agreements. Each Stockholder, by this Agreement, and with respect to such Stockholder's Shares, severally and not jointly, hereby agrees to terminate, subject to the occurrence of, and effective immediately prior to, the First Effective Time any stockholder agreements, voting agreements, registration rights agreements, co-sale agreements and any other similar Contracts between the Company and holders of Company Capital Stock, including rights under any letter agreement providing for redemption rights, put rights, purchase rights, information rights, rights to consult with and advise management, inspection rights, preemptive rights, board of directors observer rights or rights to receive information delivered to the board of directors or other similar rights not generally available to stockholders of the Company between the Stockholder and the Company, including Investor Agreements, but excluding, for the avoidance of doubt, any rights the Stockholder may have that relate to any indemnification, commercial, development or employment agreements or arrangements between such Stockholder and the Company or any subsidiary of the Company, which shall survive in accordance with their terms. Each Stockholder hereby terminates and waives all rights of first refusal, redemption rights and rights of notice of the Merger and the other transactions contemplated by the Merger Agreement, effective as of immediately prior to, and contingent upon, the First Effective Time.

11. Termination. This Agreement shall terminate and shall cease to be of any further force or effect as of the earliest of (a) such date and time as the Merger Agreement shall have been terminated pursuant to the terms thereof, (b) the First Effective Time and (c) the time this Agreement is terminated upon the written agreement of the Stockholder, the Company and Parent (the "Expiration Date"); provided, however, that (i) Section 12 shall survive the termination of this Agreement and (ii) the termination of this Agreement shall not relieve any Party from any liability for any material and willful breach of this Agreement prior to the First Effective Time.

12. Miscellaneous Provisions.

(a) Amendments. No amendment of this Agreement shall be effective against any Party unless it shall be in writing and signed by each of the Parties.

(b) Entire Agreement; Counterparts; Exchanges by Electronic Transmission or Facsimile. This Agreement constitutes the entire agreement between the Parties and supersedes all other prior agreements, arrangements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by all Parties by facsimile or electronic transmission in PDF format shall be sufficient to bind the Parties to the terms and conditions of this Agreement.

Page 6

(c) Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws. In any action or proceeding between any of the Parties arising out of or relating to this Agreement, each of the Parties: (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, (ii) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (i) of this Section 12(c), (iii) waives any objection to laying venue in any such action or proceeding in such courts, (iv) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any Party, (v) agrees that service of process upon such Party in any such action or proceeding shall be effective if notice is given in accordance with Section 12(h) of this Agreement and (vi) irrevocably and unconditionally waives the right to trial by jury.

(d) Assignment. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the Parties and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of a Party's rights or obligations hereunder may be assigned or delegated (except pursuant to the Merger) by such Party without the prior written consent of the other Parties, and any attempted assignment or delegation of this Agreement or any of such rights or obligations by such Party without the other Parties' prior written consent shall be void and of no effect.

(e) No Third-Party Rights. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

(f) Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

(g) Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms (including failing to take such actions as are required of it hereunder to consummate this Agreement) or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, this being in addition to any other remedy to which they are entitled at law or in

Page 7

equity, and each of the Parties waives any bond, surety or other security that might be required of any other Party with respect thereto. Each of the Parties further agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity.

(h) Notices. All notices and other communications hereunder shall be in writing and shall be deemed duly delivered (i) one (1) Business Day after being sent for next Business Day delivery, fees prepaid, via a reputable international overnight courier service, (ii) upon delivery in the case of delivery by hand or (iii) on the date delivered in the place of delivery if sent by email or facsimile (with a written or electronic confirmation of delivery) prior to 6:00 p.m. (New York City time), otherwise on the next succeeding Business Day, (A) if to the Company or Parent, to the address, electronic mail address or facsimile provided in Section 11.7 of the Merger Agreement, including to the persons designated therein to receive copies; and/or (B) if to the Stockholder, to the Stockholder's address, electronic mail address or facsimile shown below Stockholder's signature to this Agreement.

(i) Confidentiality. Except to the extent required by applicable Law or regulation, the Stockholder shall hold any non-public information regarding the Company, this Agreement, the Merger Agreement and the Contemplated Transactions in strict confidence and shall not divulge any such information to any third person, except to the extent such information has been publicly disclosed by the Company or Parent in connection with their entry into the Merger Agreement and this Agreement; provided, however, that the Stockholder may disclose such information to its Affiliates, attorneys, accountants, consultants, and other advisors (provided that such Persons are subject to confidentiality obligations at least as restrictive as those contained herein). Neither the Stockholder nor any of its Affiliates (other than the Company, whose actions shall be governed by the Merger Agreement), shall issue or cause the publication of any press release or other public announcement with respect to the Company, Parent, the Merger Subs, this Agreement, the Contemplated Transactions, the Merger Agreement or the other transactions contemplated hereby or thereby without the prior written consent of the Company and Parent, except as may be required by applicable Law in which circumstance such announcing Party shall make reasonable efforts to consult with the Company and Parent to the extent practicable.

(a) Until the Expiration Date, at every meeting of the Shareholders of Parent called to vote upon the Parent Shareholder Matters, however called, and at every adjournment or postponement thereof, and on every action or approval by written consent of the shareholders of Parent, the Shareholder shall be present (in person or by proxy) and vote, or exercise its right to consent with respect to, all Shares held by the Shareholder (A) in favor of the Parent Shareholder Matters, and (B) against any Acquisition Proposal.

(b) If the Shareholder is the beneficial owner, but not the record holder, of Shares, the Shareholder agrees to take all actions necessary to cause the record holder and any nominees to be present (in person or by proxy) and vote all the Shareholder's Shares in accordance with this Section 3.

(c) In the event of a stock split, stock dividend or distribution, or any change in the capital stock of Parent by reason of any split-up, reverse stock split, recapitalization, combination, reclassification, reincorporation, exchange of shares or the like, the term "Shares" shall be deemed to refer to and include such shares as well as all such stock dividends and distributions and any securities into which or for which any or all of such shares may be changed or exchanged or which are received in such transaction.

4. Action in Shareholder Capacity Only. The Shareholder is entering into this Agreement solely in the Shareholder's capacity as a record holder and beneficial owner, as applicable, of its Shares and not in the Shareholder's capacity as a director or officer of Parent. Nothing herein shall limit or affect the Shareholder's ability to exercise the Shareholder's fiduciary duties as an officer or director of Parent.

5. Irrevocable Proxy. The Shareholder hereby revokes (or agrees to cause to be revoked) any proxies that the Shareholder has heretofore granted with respect to its Shares. In the event and to the extent that the Shareholder fails to vote the Shares in accordance with Section 3 at any applicable meeting of the shareholders of Parent or pursuant to any applicable written consent of the shareholders of Parent, the Shareholder shall be deemed to have irrevocably granted to, and appointed, the Company as his, her or its proxy and attorney-in-fact (with full power of substitution), for and in its name, place and stead, to (a) attend any all meetings of the Parent shareholders with respect to any of the matters specified in Section 3 and (b) vote, express consent, dissent or grant, withhold or issue instructions to the record holder to vote his, her or its Shares in any action by written consent of Parent shareholders or at any meeting of Parent shareholders called with respect to any of the matters specified in, and in accordance and consistent with, Section 3 of this Agreement. The Company agrees not to exercise the proxy granted herein for any purpose

Page 3

other than the purposes described in this Agreement. Except as otherwise provided for herein (including the next sentence), the Shareholder hereby affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked and that such irrevocable proxy is executed and intended to be irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of the Shareholder, as applicable) and shall not be terminated by operation of law or upon the occurrence of any other event other than the termination of this Agreement pursuant to Section 9. Notwithstanding any other provisions of this Agreement, the irrevocable proxy granted hereunder shall automatically terminate on the Expiration Date. The Shareholder authorizes such attorney and proxy to substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the Secretary of Parent. The Shareholder hereby affirms that the proxy set forth in this Section 5 is given in connection with and granted in consideration of and as an inducement to the Company to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Shareholder under Section 3. With respect to any Shares that are owned beneficially by the Shareholder but are not held of record by the Shareholder (other than shares beneficially owned by the Shareholder that are held in the name of a bank, broker or nominee), the Shareholder shall take all action necessary to cause the record holder of such Shares to grant the irrevocable proxy and take all other actions provided for in this Section 5 with respect to such Shares.

6. No Solicitation. The Shareholder agrees not to directly or indirectly, including through any of its officers, directors or agents, take any action that Parent is prohibited from taking pursuant to Section 5.4 of the Merger Agreement and Section 5.4 of the Merger Agreement is hereby incorporated by reference mutatis mutandis. The Stockholder hereby represents and warrants that the Stockholder has read Section 5.4 of the Merger Agreement.

7. Documentation and Information. The Shareholder shall permit and hereby authorizes Parent and the Company to publish and disclose in all documents and schedules filed with the SEC, and any press release or other disclosure document that Parent or the Company reasonably determines to be necessary in connection with the Merger and any of the Contemplated Transactions, a copy of this Agreement, the Shareholder's identity and ownership of the Shares and the nature of the Shareholder's commitments and obligations under this Agreement.

(c) This Agreement has been duly and validly executed and delivered by the Shareholder and (assuming the due authorization, execution and delivery by the other Parties) constitutes a valid and binding agreement of the Shareholder enforceable against the Shareholder in accordance with its terms, subject to the Enforceability Exceptions. The execution and delivery of this Agreement by the Shareholder and the performance by the Shareholder of the agreements and obligations hereunder will not result in any breach or violation of or be in conflict with or constitute a default under any term of any Contract or, if applicable, any provision of an organizational document (including a certificate of incorporation) to or by which the Shareholder is a party or bound, or any applicable law to which the Shareholder (or any of the Shareholder's assets) is subject or bound, except for any such breach, violation, conflict or default which, individually or in the aggregate, would not reasonably be expected to materially impair or adversely affect the Shareholder's ability to perform its obligations under this Agreement.

(d) The execution, delivery and performance of this Agreement by the Shareholder do not and will not require any consent, approval, authorization or permit of, action by, filing with or notification to, any Governmental Authority, except for any such consent, approval, authorization, permit, action, filing or notification the failure of which to make or obtain, individually or in the aggregate, has not and would not materially impair the Shareholder's ability to perform its obligations under this Agreement.

(e) The Shareholder has had the opportunity to review the Merger Agreement and this Agreement with counsel of the Shareholder's own choosing. The Shareholder has had an opportunity to review with its own tax advisors the tax consequences of the Merger and the Contemplated Transactions.

The Shareholder understands that such Shareholder (and not Parent, the Company or the Surviving Corporation) shall be responsible for such Shareholder's tax liability that may arise as a result of the Merger or the Contemplated Transactions. The Shareholder understands and acknowledges that the Company, Parent and the Merger Subs are entering into the Merger Agreement in reliance upon the Shareholder's execution, delivery and performance of this Agreement.

(f) With respect to the Shareholder, as of the date hereof, there is no action, suit, investigation or proceeding pending against, or, to the knowledge of the Shareholder, threatened against, the Shareholder or any of the Shareholder's properties or assets (including the Shares) that would reasonably be expected to prevent or materially delay or impair the ability of the Shareholder to perform its obligations hereunder or to consummate the transactions contemplated hereby.

9. Termination. This Agreement shall terminate and shall cease to be of any further force or effect as of the earliest of (a) such date and time as the Merger Agreement shall have been terminated pursuant to the terms thereof, (b) the First Effective Time, (c) the amendment of the Merger Agreement, without the prior written consent of the Shareholder, in a manner that affects the economics or material terms of the Merger Agreement in a manner that is adverse to the Shareholder and (d) the time this Agreement is terminated upon the written agreement of the Shareholder, the Company and Parent (the "Expiration Date"); provided, however, that (i) Section 10 shall survive the termination of this Agreement, and (ii) the termination of this Agreement shall not relieve any Party from any liability for any material and willful breach of this Agreement prior to the First Effective Time.

10. Miscellaneous Provisions.

(a) Amendments. No amendment of this Agreement shall be effective against any Party unless it shall be in writing and signed by each of the Parties.

(b) Entire Agreement; Counterparts; Exchanges by Electronic Transmission or Facsimile. This Agreement constitutes the entire agreement between the Parties and supersedes all other prior agreements, arrangements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. This Agreement may be executed in several counterparts, each of which shall be deemed an original and all of which shall constitute one and the same instrument. The exchange of a fully executed Agreement (in counterparts or otherwise) by all Parties by facsimile or electronic transmission in PDF format shall be sufficient to bind the Parties to the terms and conditions of this Agreement.

(c) Applicable Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws, except to the extent the provisions of the laws of the Commonwealth of Massachusetts are mandatorily applicable to the Merger or the fiduciary duties of the board of directors or officers of Parent and provided, that the provisions of this Agreement which by their terms are governed by the laws of the Commonwealth of Massachusetts shall be governed and construed in accordance with the laws of the Commonwealth of Massachusetts. In any action or proceeding between any of the Parties arising out of or relating to this Agreement, each of the Parties: (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, (ii) agrees that all claims in respect of such action or proceeding shall be heard and determined exclusively in accordance with clause (i) of this Section 10(c), (iii) waives any objection to laying venue in any such action or proceeding in such courts, (iv) waives any objection that such courts are an inconvenient forum or do not have jurisdiction over any Party, (v) agrees that service of process upon such Party in any such action or proceeding shall be effective if notice is given in accordance with Section 10(h) of this Agreement and (vi) irrevocably and unconditionally waives the right to trial by jury.

(d) Assignment. This Agreement shall be binding upon, and shall be enforceable by and inure solely to the benefit of, the Parties and their respective successors and permitted assigns; provided, however, that neither this Agreement nor any of a Party's rights or obligations hereunder may be assigned or delegated (except pursuant to the Merger) by such Party without the prior written consent of the other Parties, and any attempted assignment or delegation of this Agreement or any of such rights or obligations by such Party without the other Parties' prior written consent shall be void and of no effect.

(e) No Third-Party Rights. Nothing in this Agreement, express or implied, is intended to or shall confer upon any Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

(f) Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions of this Agreement or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If a final judgment of a court of competent jurisdiction declares that any term or provision of this Agreement is invalid or unenforceable, the Parties agree that the court making such determination shall have the power to limit such term or provision, to delete specific words or phrases or to replace such term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be valid and enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the Parties agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term or provision.

Page 6

(g) Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms (including failing to take such actions as are required of it hereunder to consummate this Agreement) or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof the Court of Chancery of the State of Delaware or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or the United States District Court for the District of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity, and each of the Parties waives any bond, surety or other security that might be required of any other Party with respect thereto. Each of the Parties further agrees that it will not oppose the granting of an injunction, specific performance or other equitable relief on the basis that any other Party has an adequate remedy at law or that any award of specific performance is not an appropriate remedy for any reason at law or in equity.

(h) Notices. All notices and other communications hereunder shall be in writing and shall be deemed duly delivered (i) one (1) Business Day after being sent for next Business Day delivery, fees prepaid, via a reputable international overnight courier service, (ii) upon delivery in the case of delivery by hand or (iii) on the date delivered in the place of delivery if sent by email or facsimile (with a written or electronic confirmation of delivery) prior to 6:00 p.m. (New York City time), otherwise on the next succeeding Business Day, (A) if to the Company or Parent, to the address, electronic mail address or facsimile provided in Section 11.7 of the Merger Agreement, including to the persons designated therein to receive copies; and/or (B) if to the Shareholder, to the Shareholder's address, electronic mail address or facsimile shown below Shareholder's signature to this Agreement.

(i) Confidentiality. Except to the extent required by applicable Law or regulation, the Shareholder shall hold any non-public information regarding the Company, this Agreement, the Merger Agreement and the Contemplated Transactions in strict confidence and shall not divulge any such information to any third person, except to the extent such information has been publicly disclosed by the Company or Parent in connection with their entry into the Merger Agreement and this Agreement; provided, however, that the Shareholder may disclose such information to its Affiliates, attorneys, accountants, consultants, and other advisors (provided, that such Persons are subject to confidentiality obligations at least as restrictive as those contained herein). Neither the Shareholder nor any of its Affiliates (other than Parent, whose actions shall be governed by the Merger Agreement), shall issue or cause the publication of any press release or other public announcement with respect to Parent, this Agreement, the Contemplated Transactions, the Merger Agreement or the other transactions contemplated hereby or thereby without the prior written consent of the Company and Parent, except as may be required by applicable Law in which circumstance such announcing Party shall make reasonable efforts to consult with the Company and Parent to the extent practicable.

2. Purchase and Sale of Securities.

2.1 Purchase and Sale. On the Closing Date, upon the terms and subject to the conditions set forth herein, the Company agrees to sell, and the Investors, severally and not jointly, agree to purchase, the number of Initial Shares equal to (rounded down to the nearest whole Initial Share) (i) the aggregate commitment amount set forth under the heading "Commitment Amount" and opposite such Investor's name on Exhibit A (the "Commitment Amount") divided by (ii) the Share Price; provided, however, for any Investor that has provided notice to the Company at least ten (10) Business Days prior to the Closing that such Investor would beneficially own (when aggregated with all Securities then beneficially owned by the Investor and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder)) in excess of the Beneficial Ownership Limitation, or as such Investor may otherwise choose, in lieu of purchasing Initial Shares such Investor may elect to purchase Pre-Funded Warrants to purchase a number of shares of Common Stock issuable upon exercise of the Pre-Funded Warrants (the "Pre-Funded Warrant Shares") equal to (rounded down to the nearest whole Pre-Funded Warrant Share) (i) the Commitment Amount (or any remainder thereof) divided by (ii) the Pre-Funded Warrant Price in lieu of Initial Shares in such manner to result in the same Aggregate Purchase Amount being paid by such Investor in the aggregate (including upon exercise of such Pre-Funded Warrants). The "Beneficial Ownership Limitation" shall initially be set at the discretion of each Investor to a percentage designated by such Investor on its signature page hereto between 0% and 14.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of the Initial Shares and Pre-Funded Warrants on the Closing Date (collectively, the "Securities"); provided that such percentage shall be set at 9.99% for any Investor that does not make such designation on its signature page hereto. Notwithstanding the foregoing, by written notice to the Company, any Investor may reset the Beneficial Ownership Limitation percentage to a higher or lower percentage, not to exceed 19.99%;

6

provided that any increase prior to the Closing will not be effective until the sixty-first (61st) day after such written notice is delivered to the Company. Upon such a change by an Investor of the Beneficial Ownership Limitation, the Beneficial Ownership Limitation may not be further amended by such Investor without first providing the minimum notice required by this Section 2.1. Notwithstanding anything to the contrary set forth in this Agreement, for any Investor that has provided notice to the Company that this sentence shall apply to it, (i) the Investor shall not be required to purchase Pre-Funded Warrants and (ii) the Company shall not issue or sell, and the Investor shall not purchase or acquire, any Initial Shares which, when aggregated with all shares of Common Stock then beneficially owned by the Investor and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule 13d-3 promulgated thereunder), would result in the beneficial ownership by the Investor of more than 14.99% of the outstanding shares of Common Stock immediately after giving effect to the Closing and the consummation of the transactions contemplated hereby, and the number of Initial Shares and the Aggregate Purchase Amount for such Investor shall be reduced accordingly.

2.2 Closing. Subject to the satisfaction or waiver of the conditions set forth in Section 6, the closing of the purchase and sale of the Securities (the "Closing" and the date on which the Closing occurs, the "Closing Date") shall occur remotely via the exchange of documents and signatures immediately prior to the First Effective Time (as defined in the Merger Agreement), or at such other time as agreed to by the Company and the Investor Majority. Not less than three (3) Business Days prior to the anticipated Closing Date, the Company shall provide written notice to the Investors (the "ClosingNotice") of the anticipated Closing Date and the wire instructions for delivery of the Aggregate Purchase Amount. At the Closing, the Securities shall be issued and registered in the name of such Investor, or in such nominee name(s) as designated by such Investor, representing the number and type of Securities to be purchased by such Investor at such Closing as set forth in Exhibit A, in each case against payment to the Company of the purchase price therefor (the "Aggregate Purchase Amount") in full, either by (x) wire transfer to the Company of immediately available funds (a "Wire"), at or prior to the Closing, in accordance with wire instructions provided by the Company to the Investors in the Closing Notice; (y) the cancellation of Convertible Securities or other debt of the Company or its Subsidiaries (including any outstanding principal, interest or any other amounts due thereon) set forth under the heading "Convertible Securities Amount" and opposite such Investor's name in Exhibit A (any such cancellation, a "Contribution"); or (z) a combination of such methods. On the Closing Date, the Company will (A) cause the Transfer Agent to issue the Initial Shares in book-entry form, free and clear of all restrictive and other legends (except as expressly provided in Section 4.10 hereof) and the Company shall provide evidence of such issuance from the Company's Transfer Agent as soon as reasonably practical following the Closing Date to each Investor and (B) deliver to such Investor (or such Investor's designated custodian per its delivery instructions), or in such nominee name(s) as designated by such Investor, a Pre-Funded Warrant exercisable for a number of shares of Common Stock as set forth in Exhibit A with respect to such Investor. If the Closing has not occurred within two (2) Business Days after the expected Closing Date, unless otherwise agreed by the Company and such Investor, the Company shall promptly (but no later than one (1) Business Day thereafter) return the previously wired Aggregate Purchase Amount to each respective Investor by wire transfer of United States dollars in immediately available funds to the account specified by each Investor, and any book entries for the Securities shall be deemed cancelled; provided that, unless this Agreement has been terminated pursuant to Section 7, such return of funds shall not terminate this Agreement or relieve such Investor of its obligation to purchase, or the Company of its obligation to issue and sell, the Securities at the Closing. Notwithstanding the foregoing and anything in this Agreement to the contrary, (i) the Company may amend Exhibit A up to three (3) Business Days prior to the Closing, without the consent of the other parties hereto, to reflect the number of Securities purchased, the Aggregate Purchase Amount to be paid and the Convertible Securities Amount to be Contributed, in each case, by each applicable Investor (provided that, except as contemplated herein, no Investor's aggregate commitment amount set forth under the heading "Commitment Amount" as set forth on Exhibit A may be reduced without such Investor's prior written consent (not to be unreasonably withheld, conditioned or delayed), and shall provide such updated

7

Exhibit A to an Investor upon request, and (ii), as may be agreed to among the Company and one or more Investors, if an Investor is (a) an investment company registered under the Investment Company Act of 1940, as amended, (b) advised by an investment adviser subject to regulation under the Investment Advisers Act of 1940, as amended, or (c) otherwise subject to internal policies and/or procedures relating to the timing of funding and issuance of securities, such Investor shall not be required to wire its Aggregate Purchase Amount until it confirms receipt of evidence of the issuance of such Investor's Initial Shares from the Transfer Agent in form and substance reasonably acceptable to the Investor (and the Company shall use reasonable best efforts to cause the Transfer Agent to deliver such evidence) and, if applicable, copies of such Investor's Pre-Funded Warrants.

2.3 Conversion and Termination of Convertible Securities. Notwithstanding anything in this Agreement to the contrary, by executing and delivering this Agreement, each Investor holding one or more Convertible Securities prior to the Closing hereby irrevocably agrees that:

(a) the aggregate amount of all such Convertible Securities (including any outstanding principal, interest or any other amounts) held by such Investor is set forth under the heading "Convertible Securities Amount" and opposite such Investor's name in Exhibit A;

(b) such Investor is the sole owner of all right, title and interest in and to the Convertible Securities corresponding to the amounts set forth under the heading "Convertible Securities Amount" and opposite such Investor's name in Exhibit A;

(c) at the Closing, (i) all of such Investor's Convertible Securities will automatically and without any action on the part of such Investor convert into that number of Securities as is calculated in accordance with Section 2.1 based on such Investor's Aggregate Purchase Amount (whether paid via Wire or Contribution), regardless of whether any such Convertible Securities or an affidavit of loss therefor is actually delivered in original or other form to the Company, and (ii) any original Convertible Securities held by (or delivered, electronically or otherwise, to) the Company or any Subsidiary, as applicable, shall be cancelled (and marked cancelled) by the Company or any Subsidiary, as applicable, upon or following the Closing;

(d) with respect to any Contribution by such Investor, (i) such Investor (on behalf of itself and all beneficial owners of such Investor's Convertible Securities) and Company (on behalf of itself and its Subsidiaries) hereby agree that any Convertible Securities that are Contributed hereby are and will be deemed for all purposes to have been amended and modified by virtue hereof to the full extent necessary to permit and facilitate their conversion as provided in this Agreement into Securities and (ii) such Investor's Securities are issued in full and complete discharge and satisfaction of all obligations of the Company or its Subsidiaries, as applicable (including any outstanding principal, interest or any other amounts) under such Investor's Convertible Securities, and such Convertible Securities will be terminated in full and will be null, void and of no further force or effect automatically immediately upon the Closing, provided that the foregoing will not impair the right of such Investor to receive the applicable number of Securities calculated in accordance with Section 2.1 above; and

(e) the Company and its Subsidiaries, affiliates, and agents shall be entitled to deduct and withhold from the amounts deliverable in satisfaction of such Investor's Convertible Securities (including any Securities otherwise issuable with respect thereto) such amounts, if any, as are required to be deducted and withheld under the Code or any other applicable tax law. To the extent that amounts are so deducted and withheld and duly paid over to the appropriate tax authority, such withheld amounts shall be treated for all purposes of this Agreement as having been delivered to the person in respect of whom such deduction and withholding was made. Each person holding Convertible Securities shall, upon request, use its commercially reasonable efforts to provide the applicable withholding agent with all necessary tax

8

forms, including a duly executed IRS Form W-9 or appropriate version of IRS Form W-8, as applicable. Prior to withholding any amounts pursuant to this Section 2.3(e), the Company (and its Subsidiaries, affiliates, and agents) shall use commercially reasonable efforts to notify such Investor, and the Company and such Investor shall cooperate in good faith to reduce or eliminate any such withholding.

3. Representations and Warranties of the Company. The Company hereby represents and warrants to each of the Investors and the Placement Agents that the statements contained in this Section 3 are true and correct as of the date hereof and as of the Closing Date (except for the representations and warranties that speak as of a specific date, which shall be made as of such date):

3.1 Organization and Power. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware, has the requisite power and authority to own, lease and operate its properties and to carry on its business as now conducted and is qualified to do business in each jurisdiction in which the character of its properties or the nature of its business requires such qualification, except where such failure to be in good standing or to have such power and authority or to so qualify would not reasonably be expected to have a Material Adverse Effect. Each of the Company's subsidiaries (collectively, the "Subsidiaries") is wholly owned by the Company. Each of the Subsidiaries is duly incorporated and validly existing and in good standing under the laws of the jurisdiction of its incorporation and has the requisite power and authority to carry on its business as now conducted and to own or lease its properties. Each of the Subsidiaries is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required unless the failure to so qualify has not had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

3.2 Capitalization. The authorized capital stock of the Company consists of 122,363,552 shares of Common Stock and 95,000,000 shares of preferred stock, par value $0.0001 per share. All of the issued and outstanding shares of Common Stock have been duly authorized and validly issued and are fully paid and non-assessable. None of the outstanding shares of capital stock of the Company were issued in violation of any preemptive or other similar rights of any securityholder of the Company which have not been waived, and such shares were issued in compliance in all material respects with applicable state and federal securities law and any rights of third parties. Except for any employment agreement entered into in the ordinary course of business, there are no securities or instruments issued by or to which the Company is a party containing anti-dilution or similar provisions that will be triggered (which, for the avoidance of doubt, excludes any such anti-dilution or similar provision that will be waived in connection with the transactions contemplated by this Agreement and the Merger Agreement) by the issuance of the Securities pursuant to this Agreement.

3.3 Registration Rights. Except as set forth in the Transaction Agreements, the Company is presently not under any obligation, and has not granted any rights, to register under the Securities Act any of the Company's presently outstanding securities or any of its securities that may hereafter be issued that have not expired or been satisfied or waived.

3.4 Authorization. The Company has all requisite corporate power and authority to enter into the Transaction Agreements and to carry out and perform its obligations under the terms of the Transaction Agreements, including the issuance and sale of the Securities and the issuance of the Pre-Funded Warrant Shares. Except for the Required Company Stockholder Vote (as defined in the Merger Agreement), all corporate action on the part of the Company, its officers, directors and stockholders necessary for the authorization of the Securities and the Pre-Funded Warrant Shares, the authorization, execution, delivery and performance of the Transaction Agreements and the consummation of the transactions contemplated herein, including the issuance and sale of the Securities and the Pre-Funded Warrant Shares and the reservation of the Pre-Funded Warrant Shares, has been taken, including, without

9

limitation, the approval of the Board of Directors (or a committee thereof) in accordance with Sections 144(a)(1) and 144(b)(1) of the General Corporation Law of the State of Delaware to the extent applicable. This Agreement has been duly executed and delivered by the Company and assuming the due authorization, execution and delivery by each Investor and that this Agreement constitutes the legal, valid and binding agreement of each Investor, this Agreement and each of the Pre-Funded Warrants constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws relating to or affecting creditors generally or by general equity principles (regardless of whether such enforceability is considered in a proceeding in equity or at law). Upon its execution by the Company and the other parties thereto and assuming that it constitutes legal, valid and binding agreements of the other parties thereto, the Registration Rights Agreement will constitute a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws relating to or affecting creditors generally or by general equity principles (regardless of whether such enforceability is considered in a proceeding in equity or at law).

3.5 Valid Issuance. The Initial Shares being purchased by the Investors hereunder have been duly and validly authorized and, upon issuance pursuant to the terms hereof, against full payment therefor in accordance with the terms of this Agreement, will be duly and validly issued, fully paid and non-assessable and will be issued free and clear of any liens or other restrictions (other than those as provided in the Transaction Agreements or restrictions on transfer under applicable state and federal securities laws) and the holder of the Initial Shares shall be entitled to all rights accorded to a holder of Common Stock. The Pre-Funded Warrant Shares have been duly and validly authorized and reserved for issuance and, upon issuance pursuant to the terms of the Pre-Funded Warrants, against full payment therefor in accordance with the terms of the Pre-Funded Warrants, will be duly and validly issued, fully paid and non-assessable and will be issued free and clear of any liens or other restrictions (other than those as provided in the Transaction Agreements or restrictions on transfer under applicable state and federal securities laws) and the holder of the Pre-Funded Warrant Shares shall be entitled to all rights accorded to a holder of Common Stock. Subject to the accuracy of the representations and warranties made by the Investors in Section 4 hereof, the offer and sale of the Securities to the Investors is and will be in compliance with applicable exemptions from (i) the registration and prospectus delivery requirements of the Securities Act and (ii) the registration and qualification requirements of applicable securities laws of the states of the United States.

3.6 No Conflict. The execution, delivery and performance of the Transaction Agreements by the Company, the issuance and sale of the Securities and the consummation of the other transactions contemplated by the Transaction Agreements will not (i) violate any provision of the Amended and Restated Certificate of Incorporation or Amended and Restated Bylaws, (ii) conflict with or result in a violation of or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation, a change of control right or to a loss of a benefit under any agreement or instrument, credit facility, franchise, license, judgment, order, statute, law, ordinance, rule or regulations, applicable to the Company or any Subsidiary or their respective properties or assets, or (iii) result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or any Subsidiary is subject (including federal and state securities laws and regulations) and the rules and regulations of any self-regulatory organization to which the Company or its securities are subject, or by which any property or asset of the Company or any Subsidiary is bound or affected, except, in the case of clauses (ii) and (iii), as would not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect.

All notices, consents, authorizations, orders, filings and registrations which the Company is required to deliver or obtain prior to the Closing pursuant to the preceding sentence have been obtained or made or will be delivered or obtained or effected, and shall remain in full force and effect, on or prior to the Closing.

The Company and its Subsidiaries have all required licenses, permits, certificates and other authorizations (collectively, "Governmental Authorizations") from such federal, state or local government or governmental agency, department or body that are currently necessary for the operation of the business of the Company and its Subsidiaries as currently conducted, except where the failure to possess currently such Governmental Authorizations has not had and is not reasonably expected to have a Material Adverse Effect. None of the Company or any Subsidiary has received any written (or, to the Company's knowledge, oral) notice regarding any revocation or material modification of any such Governmental Authorization, which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, has or would reasonably be expected to result in a Material Adverse Effect.

3.12 Intellectual Property. The Company and its Subsidiaries own, or have rights to use, all material inventions, patent applications, patents, trademarks, trade names, service names, service marks, copyrights, trade secrets, know how (including unpatented and/or unpatentable proprietary of confidential information, systems or procedures) and other intellectual property, including but not limited to such intellectual property described in the Company Presentation, that is necessary for, or used in the conduct of their respective businesses (collectively, "Intellectual Property"), except where any failure to own, possess or acquire such Intellectual Property has not had, and would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

The charges, accruals and reserves on the books of the Company in respect of any income and corporation tax liability for any years not finally determined are adequate to meet any assessments or reassessments for additional income tax for any years not finally determined, except to the extent of any inadequacy that would not result in a Material Adverse Effect.

None of the Company or any Subsidiary has received since January 1, 2025, any written notice or other communication (in writing or otherwise), whether from a governmental authority or other Person, that alleges that the Company or any Subsidiary is not in compliance with any Environmental Law and, to the knowledge of the Company, there are no circumstances that may prevent or interfere with the Company's or any Subsidiary's compliance with any Environmental Law in the future, except where such failure to comply would not reasonably be expected to have a Material Adverse Effect.

(b) The Company agrees and acknowledges that the Placement Agents may rely on its representations, warranties, agreements and covenants contained in this Agreement and each Investor agrees that the Placement Agents may rely on such Investor's representations and warranties contained in this Agreement as if such representations and warranties, as applicable, were made directly to the Placement Agents.

(c) Neither the Placement Agents nor any of their respective affiliates or representatives (1) shall be liable for any improper payment made in accordance with the information provided by the Company; (2) makes any representation or warranty, or has any responsibilities as to the validity, accuracy, value or genuineness of any information, certificates or documentation delivered by or on behalf of the Company pursuant to the Transaction Agreements or in connection with any of the transactions contemplated therein; or (3) shall be liable (x) for any action taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights or powers conferred upon them by the Transaction Agreements or (y) for anything which any of them may do or refrain from doing in connection with the Transaction Agreements, except in each case for such party's own gross negligence, willful misconduct or bad faith.

33

(d) The Company agrees that the Placement Agents and their respective affiliates and representatives shall be entitled to (1) rely on, and shall be protected in acting upon, any certificate, instrument, notice, letter or any other document or security delivered to any of them by or on behalf of the Company, and (2) be indemnified by the Company for acting as the Placement Agents hereunder pursuant to the indemnification provisions set forth in the applicable engagement letters between the Company and the Placement Agents.

8.11 Third Parties. Nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties to this Agreement any rights, remedies, claims, benefits, obligations or liabilities under or by reason of this Agreement, and no Person that is not a party to this Agreement (including, without limitation, any partner, member, shareholder, director, officer, employee or other beneficial owner of any party to this Agreement, in its own capacity as such or in bringing a derivative action on behalf of a party to this Agreement) shall have any standing as a third party beneficiary with respect to this Agreement or the transactions contemplated hereby, except as expressly set forth in this Agreement. Notwithstanding the foregoing, each Placement Agent is an intended third-party beneficiary of the representations and warranties of the Company set forth in Section 3, the representations and warranties of each Investor set forth in Section 4, Section 6.1(g) and Section 8.10 of this Agreement.

8.12 Independent Nature of Investors' Obligations and Right. The obligations of each Investor under this Agreement are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance obligations of any other Investor under this Agreement. Nothing contained herein, and no action taken by any Investor pursuant hereto, shall be deemed to constitute the Investors as, and the Company acknowledges that the Investors do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group (including a "group" within the meaning of Section 13(d)(3) of the Exchange Act), and the Company will not assert any such claim with respect to such obligations or the transactions contemplated by this Agreement and the Company acknowledges that the Investors are not acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. It is expressly understood that each provision contained in this Agreement is between the Company and an Investor, solely, and not between the Company and the Investors collectively and not between and among the Investors. The Company acknowledges and each Investor confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Investor also acknowledges that neither Gibson, Dunn & Crutcher LLP nor Cooley LLP has rendered legal advice to such Investor. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Investor to be joined as an additional party in any proceeding for such purpose. The Company has elected to provide all Investors with the same terms and Transaction Agreements for the convenience of the Company and not because it was required or requested to do so by any Investor.

8.13 Headings. The titles, subtitles and headings in this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

8.14 Counterparts. This Agreement may be executed in two (2) or more identical counterparts, all of which shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party; provided that a facsimile or pdf signature including any electronic signatures complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original, not a facsimile or pdf (or other electronic reproduction of a) signature.

8.15 Entire Agreement; Amendments. This Agreement and the other Transaction Agreements (including all schedules and exhibits hereto and thereto) constitute the entire agreement between the parties hereto respecting the subject matter hereof and thereof and supersede all prior agreements, negotiations, understandings, representations and statements respecting the subject matter hereof and thereof, whether written or oral. No amendment, modification, alteration, waiver or change in any of the terms of this Agreement shall be valid or binding upon the parties hereto unless made in writing and duly executed by the Company and the Investor Majority. Notwithstanding the foregoing, (i) this Agreement may not be amended or waived with respect to any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion and (ii) any amendment to the definition of "Share Price" (or of any of the other terms included in such definition), any change in the type of security to be issued to the Investors, and any amendment to or waiver of Section 5.5, Section 5.10, Section 6.1, Section 7.1 or this Section 8.15 shall require the consent of each Investor. The Company, on the one hand, and each Investor, on the other hand, may by an instrument signed in writing by such parties waive the performance, compliance or satisfaction by such Investor or the Company, respectively, with any term or provision hereof or any condition hereto to be performed, complied with or satisfied by such Investor or the Company, respectively. Notwithstanding the foregoing or anything else to the contrary, no amendment, modification, alteration, change or waiver of this Section 8.15 that is material and adverse to the Placement Agents shall be valid without the prior written consent of the Placement Agents, which consent may be granted or withheld in the sole discretion of the Placement Agents. In addition, no consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of this Agreement unless the same consideration (other than the reimbursement of legal fees) also is offered to all Investors. For the avoidance of doubt, an amendment to this Agreement after the date hereof allowing for the sale of additional Securities ("Additional Securities") to one or more Persons (whether or not an existing Investor) shall only require the approval of the Company and the Investor Majority; provided that the price paid for such Additional Securities is at least 15% greater than the Share Price and Pre-Funded Warrant Price, as applicable.

8.16 Survival. The covenants, representations and warranties made by each party hereto contained in this Agreement shall survive the Closing and the delivery of the Securities in accordance with their respective terms. Each Investor shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

8.17 Mutual Drafting. This Agreement is the joint product of each Investor and the Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto.

8.18 Arm's Length Negotiations. For the avoidance of doubt, the parties acknowledge and confirm that the terms and conditions of the Securities were determined as a result of arm's-length negotiations.

8.19 Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

Registrable Securities shall cease to be Registrable Securities (and the Company shall not be required to maintain the effectiveness of any, or file another, Registration Statement hereunder with respect thereto) upon the earliest to occur of (A) the date on which such Investor shall have resold such Registrable Securities covered by the Registration Statement pursuant to the Registration Statement, (B) such Registrable Securities have been previously sold by such Investor in accordance with Rule 144, (C) such securities become eligible for resale by such Investor without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for the Company to be in compliance with the current public information requirement under Rule 144, (D) with respect to Registrable Securities held by an Investor that is not an affiliate of the Company, upon exchange of such Registrable Securities for unrestricted shares under an effective registration statement on Form S-4, if available, or if unavailable, another appropriate form filed with the SEC, and (E) five (5) years after the date of this Agreement.

(g) "Registration Statement" means any registration statement of the Company filed with, or to be filed with, the SEC under the Securities Act, that Registers Registrable Securities, including the related preliminary or final prospectus, amendments and supplements to such registration statement, including pre- and post-effective amendments, and all exhibits and all material incorporated by reference in such registration statement as may be necessary to comply with applicable securities laws. "Registration Statement" shall also include a New Registration Statement, as amended when each became effective, including all documents filed as part thereof or incorporated by reference therein, and including any information contained in a prospectus subsequently filed with the SEC.

2

(h) "SEC Guidance" means (i) any publicly-available written or oral guidance of the SEC staff, or any comments, requirements or requests of the SEC staff (whether or not publicly-available); provided, that any such oral guidance, comments, requirements or requests are reduced to writing by the SEC (and shared with the Investors upon request if not publicly-available) and (ii) the Securities Act.

(i) "Selling Expenses" means all underwriting discounts and selling commissions applicable to the sale of Registrable Securities and all similar fees and commissions relating to an Investor's disposition of its Registrable Securities.

(a) Mandatory Registration. The Company shall, as promptly as reasonably practicable and in any event no later than the Filing Deadline, prepare and file with the SEC an initial Registration Statement (the "Initial Registration Statement") covering the resale of all Registrable Securities. Before filing the Registration Statement, the Company shall furnish to the Investors a copy of the Registration Statement. The Investors and their respective counsel shall have at least three (3) Business Days prior to the anticipated filing date of a Registration Statement to review and comment upon such Registration Statement and any amendment or supplement to such Registration Statement and any related prospectus (including any documents incorporated by reference therein), prior to its filing with the SEC. Subject to any SEC comments, such Registration Statement shall include the plan of distribution substantially in the form attached hereto as Exhibit B. Such Registration Statement also shall cover, to the extent allowable under the Securities Act and the rules promulgated thereunder (including Rule 416), such indeterminate number of additional shares of Common Stock resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. The Company shall (a) consider in good faith any comments as the Investor or its counsel reasonably proposed by the Investor to such document prior to being so filed with the SEC, and (b) not file any Registration Statement or related prospectus or any amendment or supplement thereto containing information regarding the Investor to which Investor reasonably believes contains untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, unless such information is required (in the opinion of the Company) to comply with any applicable law or regulation or SEC Guidance. Each Investor shall furnish all information reasonably requested by the Company with respect to such Investor as shall be reasonably required in connection with any registration referred to in this Agreement.

(b) Effectiveness. The Company shall use its commercially reasonable efforts to have the Initial Registration Statement and any amendment declared effective by the SEC at the earliest possible date but no later than the earlier of the ninetieth (90th) calendar day following the initial filing date of the Initial Registration Statement if the SEC notifies the Company that it will "review" the Initial Registration Statement and (b) the fifth (5th) Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the SEC that the Initial Registration Statement will not be "reviewed" or will not be subject to further review (the "Effectiveness Deadline"). The Company shall notify the Investor by e-mail as promptly as practicable, and in any event, within twenty-four (24) hours, after the Initial Registration Statement is declared effective or is supplemented and shall provide the Investor with copies of any related prospectus to be used in connection with the sale or other disposition of the securities covered thereby. The Company shall use commercially reasonable efforts to keep the Initial Registration Statement continuously effective pursuant to Rule 415 promulgated under the Securities Act and available for the resale by the Investors of all of the Registrable Securities covered thereby at all times until the earlier to occur of the following events: (i) the date on which the Investors shall have resold all the Registrable Securities covered thereby; (ii) the date on which the Registrable Securities may be resold by the Investors without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, and without the requirement for the Company to be in compliance with the current public information

3

requirement under Rule 144 under the Securities Act or any other rule of similar effect and (iii) five (5) years after the date of this Agreement (the "Registration Period"). The Initial Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading.

(c) Sufficient Number of Shares Registered. In the event the number of shares available under the Initial Registration Statement at any time is insufficient to cover the Registrable Securities, the Company shall, to the extent necessary and permissible, amend the Initial Registration Statement or file a new registration statement (together with any prospectuses or prospectus supplements thereunder, a "New Registration Statement"), so as to cover all of such Registrable Securities as soon as reasonably practicable, but in any event not later than the Filing Deadline. The Company shall use its commercially reasonable efforts to have such amendment and/or New Registration Statement become effective as soon as reasonably practicable following the filing thereof but no later than the earlier of (a) the seventy-fifth (75th) calendar day following the initial filing date of the New Registration Statement if the SEC notifies the Company that it will "review" the New Registration Statement and (b) the fifth (5th) Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the SEC that the New Registration Statement will not be "reviewed" or will not be subject to further review. The provisions of Sections 2(a) and 2(b) shall apply to the New Registration Statement, except as modified hereby.

(d) Allowable Delays. On no more than two (2) occasions in any twelve (12)-month period and for not more than thirty (30) consecutive days or for a total of not more than sixty (60) days, the Company may delay the effectiveness of the Initial Registration Statement or any other Registration Statement, or suspend the use of any prospectus included in any Registration Statement, in the event that the Board of Directors reasonably determines, in good faith and upon advice of legal counsel, that such delay or suspension is necessary to (A) delay the disclosure of material non-public information concerning the Company, including in connection with the negotiation or consummation of a material transaction by the Company that is pending, that would require additional disclosure by the Company in the Registration Statement of material non-public information that the Company has a bona fide business purpose for preserving as confidential and the non-disclosure of which would be expected, in the reasonable determination of the Board of Directors, upon advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements, or (B) amend or supplement the affected Registration Statement or the related prospectus so that such Registration Statement or prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the case of the prospectus in light of the circumstances under which they were made, not misleading (an "Allowed Delay"); provided, that the Company shall promptly (a) notify each Investor in writing of the commencement of an Allowed Delay, but shall not (without the prior written consent of an Investor) disclose to such Investor any material non-public information giving rise to an Allowed Delay, (b) advise the Investors in writing to cease all sales under the applicable Registration Statement until the end of the Allowed Delay and (c) use commercially reasonable efforts to terminate an Allowed Delay as promptly as practicable. Each Investor may deliver written notice (an "Opt-Out Notice") to the Company requesting that such Investor not receive notices from the Company otherwise required by this Section 2; provided, however, that such Investor may later revoke any such Opt-Out Notice in writing, which shall be effective five (5) Business Days after the receipt thereof. Following receipt of an Opt-Out Notice from an Investor (unless subsequently revoked), the Company shall not deliver any notices pursuant to this Section 2(d) to such Investor and such Investor shall no longer be entitled to the rights associated with any such notice.

4

(e) Rule 415; Cutback. If at any time the SEC takes the position that the offering of some or all of the Registrable Securities in any Registration Statement is not eligible to be made on a delayed or continuous basis under the provisions of Rule 415 under the Securities Act (provided, however, the Company shall be obligated to use commercially reasonable efforts to advocate with the SEC for the registration of all of the Registrable Securities) or requires any Investor to be named as an "underwriter," the Company shall (i) promptly notify each holder of Registrable Securities thereof and (ii) make commercially reasonable efforts to persuade the SEC that the offering contemplated by such Registration Statement is a valid secondary offering and not an offering "by or on behalf of the issuer" as defined in Rule 415 and that none of the Investors is an "underwriter." Each Investor shall have the right to have its legal counsel, at such Investor's expense, to review and oversee any registration or matters pursuant to this Section 2(e), including to comment on any written submission made to the SEC with respect thereto. In the event that, despite the Company's commercially reasonable efforts and compliance with the terms of this Section 2(e), the SEC refuses to alter its position, the Company shall (i) remove from such Registration Statement such portion of the Registrable Securities and/or (ii) agree to such restrictions and limitations on the registration and resale of the Registrable Securities as the SEC may require to assure the Company's compliance with the requirements of Rule 415 (collectively, the "SEC Restrictions"); provided, however, that the Company shall not name any Investor as an "underwriter" in such Registration Statement without the prior written consent of such Investor (provided that, in the event an Investor withholds such consent, the Company shall have no obligation hereunder to include any Registrable Securities of such Investor in any Registration Statement covering the resale thereof until such time as the SEC no longer requires such Investor to be named as an "underwriter" in such Registration Statement or such Investor otherwise consents in writing to being so named). Any cut-back imposed on the Investors pursuant to this Section 2(e) shall be allocated among the Investors on a pro rata basis and shall be applied first to any of the Registrable Securities of an Investor that the SEC has indicated cannot be included or must be limited in the number of Registrable Securities that can be included, and thereafter to all other Investors, unless the SEC Restrictions otherwise require or provides otherwise, or an Investor otherwise agrees.

(f) Each Registration Statement filed hereunder shall be on Form S-3 (except if the Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another form in accordance with the provisions of this Section 2(f)). If Form S-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable Securities on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC.

With respect to the Registration Statement and whenever any Registrable Securities are to be Registered pursuant to Section 2, including on the Initial Registration Statement or on any New Registration Statement, the Company shall use its commercially reasonable efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations:

(a) Notifications. The Company will promptly notify the Investors of the time when any subsequent amendment to the Initial Registration Statement or any New Registration Statement, other than documents incorporated by reference, has been filed with the SEC and/or has become effective or where a receipt has been issued therefor or any subsequent supplement to a prospectus has been filed and of any request by the SEC for any amendment or supplement to the Registration Statement, any New Registration Statement or any prospectus or for additional information regarding the Investor.

5

(b) Amendments. The Company will prepare and file with the SEC any amendments, post-effective amendments or supplements to the Initial Registration Statement, any New Registration Statement or any related prospectus, as applicable, that, (a) as may be necessary to keep such Registration Statement effective for the Registration Period and to comply with the provisions of the Securities Act and the Exchange Act with respect to the distribution of all of the Registrable Securities covered thereby, or (b) in the reasonable opinion of the Investors and the Company, as may be necessary or advisable in connection with any acquisition or sale of Registrable Securities by the Investors.

(c) Investor Review. The Company will not file any amendment or supplement to the Registration Statement, any New Registration Statement or any prospectus, other than documents incorporated by reference, relating to any Investor, the Registrable Securities or the transactions contemplated hereby unless (A) such Investor and its counsel shall have been advised and afforded the opportunity to review and comment thereon at least three (3) Business Days prior to filing with the SEC and (B) the Company shall have given reasonable due consideration to any comments thereon received from such Investor or its counsel.

(d) Copies Available. The Company will furnish to any Investor whose Registrable Securities are included in any Registration Statement and its counsel copies of the Initial Registration Statement, any prospectus thereunder (including all documents incorporated by reference therein), any prospectus supplement thereunder, any New Registration Statement and all amendments to the Initial Registration Statement or any New Registration Statement that are filed with the SEC during the Registration Period (including all documents filed with or furnished to the SEC during such period that are deemed to be incorporated by reference therein), each letter written by or on behalf of the Company to the SEC or the staff of the SEC, and each item of correspondence from the SEC or the staff of the SEC, in each case relating to such Registration Statement (other than any portion thereof which contains information for which the Company has sought confidential treatment) and such other documents as such Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor that are covered by such Registration Statement, in each case as soon as reasonably practicable upon such Investor's request and in such quantities as such Investor may from time to time reasonably request; provided, however, that the Company shall not be required to furnish any document to such Investor to the extent such document is available on EDGAR.

(e) Notification of Stop Orders; Material Changes. The Company shall use commercially reasonable efforts to (i) prevent the issuance of any stop order or other suspension of effectiveness and, (ii) if such order is issued, obtain the withdrawal of any such order as soon as practicable. The Company shall advise the Investors promptly (but in no event later than 24 hours) and shall confirm such advice in writing, in each case: (i) of the Company's receipt of notice of any request by the SEC or any other federal or state governmental authority for amendment of or a supplement to the Registration Statement or any prospectus or for any additional information; (ii) of the Company's receipt of notice of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of the Initial Registration Statement or prohibiting or suspending the use of any prospectus or prospectus supplement, or any New Registration Statement, or of the Company's receipt of any notification of the suspension of qualification of the Registrable Securities for offering or sale in any jurisdiction or the initiation or contemplated initiation of any proceeding for such purpose; and (iii) of the Company becoming aware of the happening of any event, which makes any statement of a material fact made in any Registration Statement or any prospectus untrue or which requires the making of any additions to or changes to the statements then made in any Registration Statement or any prospectus in order to state a material fact required by the Securities Act to be stated therein or necessary in order to make the statements then made therein (in the case of any prospectus, in light of the circumstances under which they were made) not misleading, or of the necessity to amend any Registration Statement or any prospectus to comply with the Securities Act or any other law. The Company shall not be required to disclose to the Investors the

6

substance of specific reasons of any of the events set forth in clauses (i) through (iii) of the immediately preceding sentence (each, a "Suspension Event"), but rather, shall only be required to disclose that the event has occurred; provided that the Company shall not provide any material non-public information to the Investors in such notice. If at any time the SEC, or any other federal or state governmental authority shall issue any stop order suspending the effectiveness of any Registration Statement or prohibiting or suspending the use of any prospectus or prospectus supplement, the Company shall use its commercially reasonable efforts to obtain the withdrawal of such order at the earliest practicable time. The Company shall furnish to any Investor upon request, without charge, a copy of any correspondence from the SEC or the staff of the SEC, or any other federal or state governmental authority to the Company or its representatives relating to the Initial Registration Statement, any New Registration Statement or any prospectus, or prospectus supplement as the case may be. In the event of a Suspension Event set forth in clause (iii) of the second sentence of this Section 3(e), the Company will use its commercially reasonable efforts to publicly disclose such event as soon as reasonably practicable, or otherwise resolve the matter such that sales under Registration Statements may resume.

(f) Confirmation of Effectiveness. If requested by an Investor at any time in respect of any Registration Statement, the Company shall deliver to such Investor a written confirmation (email being sufficient) from Company's counsel of whether or not the effectiveness of such Registration Statement has lapsed at any time for any reason (including, without limitation, the issuance of a stop order) and whether or not such Registration Statement is currently effective and available to the Company for sale of Registrable Securities.

(g) Listing. The Company shall use commercially reasonable efforts to cause all Registrable Securities covered by a Registration Statement to be listed on the Nasdaq Capital Market and/or any other National Exchange upon which the Common Stock is listed.

All Registration Expenses incurred in connection with registrations pursuant to this Agreement shall be borne by the Company. All Selling Expenses relating to securities registered on behalf of an Investor shall be borne by such Investor.

(a) To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Investor, each Person, if any, who controls each Investor, the shareholders, directors, officers, partners, employees, members, managers, agents, representatives and advisors of each Investor and each Person, if any, who controls any of the foregoing within the meaning of the Securities Act or the Exchange Act (each, an "Indemnified Person"), against any losses, obligation, claims, damages, liabilities, contingencies, judgments, fines, penalties, charges and costs (including, without limitation, court costs and costs of preparation), reasonable and documented attorneys' fees, amounts paid in settlement or reasonable and documented expenses (collectively, "Indemnified Damages") reasonably incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency or body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto ("Claims"), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement or omission or alleged omission of any material fact contained in any Registration Statement, or (ii) any violation or alleged violation by the Company or any of its Subsidiaries of the Securities Act, Exchange Act or any other state securities or other "blue sky" laws of any jurisdiction in which Registrable Securities are offered or any rule or regulation promulgated thereunder applicable to the Company or its agents and relating to action or inaction required of the Company in connection with such registration of the Registrable Securities (the matters in the foregoing clauses (i) and (ii) being, collectively, "Violations"). The Company shall reimburse each Indemnified Person promptly as such Indemnified Damages are incurred and are due and payable, for any reasonable out-of-pocket legal fees or other reasonable and documented expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (A) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by the Investors or such Indemnified Person specifically for use in such Registration Statement and was reviewed and approved in writing by such Investor or such Indemnified Person expressly for use in connection with the preparation of any Registration Statement; (B) with respect to any superseded prospectus, shall not inure to the benefit of any such Person from whom the Person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the benefit of any other Indemnified Person) if the untrue statement or omission of material fact contained in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, and the Indemnified Person was promptly advised in writing not to use the outdated, defective or incorrect prospectus prior to the use giving rise to a Violation; (C) shall not be available to the extent such Claim is based on a failure of the Indemnified Person to deliver, or cause to be delivered, if required the prospectus to the Persons asserting an untrue statement or omission or alleged untrue statement or omission at or prior to the written confirmation of the sale of Registrable Securities; and (D) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 8.

9

(b) In connection with the Initial Registration Statement, any New Registration Statement or any prospectus, each Investor, severally and not jointly, agrees to indemnify, hold harmless and defend, the Company, each of its directors, and officers who signed the Initial Registration Statement or signs any New Registration Statement, and each Person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act (each, an "Indemnified Party"), against any losses, claims, damages, liabilities and expense (including reasonable attorney fees) resulting from (i) any untrue statement or alleged untrue statement or omission or alleged omission of any material fact contained in any Registration Statement or (ii) any violation or alleged violation by such Investor of its obligations under this Agreement, in each case to the extent, and only to the extent, that such violation occurs in reliance upon and in conformity with information about such Investor furnished in writing by such Investor to the Company expressly for use in connection with the preparation of the Registration Statement. In no event shall the liability of an Investor be greater in amount than the dollar amount of the proceeds (net of all expense paid by such Investor in connection with any claim relating to this Section 6 and the amount of any damages such Investor has otherwise been required to pay by reason of such untrue statement or omission) received by such Investor upon the sale of the Registrable Securities included in such Registration Statement giving rise to such indemnification obligation. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b), shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Investor, which consent shall not be unreasonably withheld, conditioned or delayed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by an Investor pursuant to Section 8.

(c) Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be, and upon such notice, the indemnifying party shall not be liable to the Indemnified Person or the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Person or the Indemnified Party in connection with the defense thereof; provided, however, that an Indemnified Person or Indemnified Party (together with all other Indemnified Persons and Indemnified Parties that may be represented without conflict by one counsel) shall have the right to retain its own counsel with the reasonable fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise unless such judgment or settlement (i) imposes no liability or obligation on, (ii) includes as an unconditional term thereof the giving of a complete, explicit and unconditional release from the party bringing such indemnified claims of all liability of the Indemnified Party or Indemnified Person in respect to or arising

10

out of such claim or litigation in favor of, and (iii) does not include any admission of fault, culpability, wrongdoing, or wrongdoing or malfeasance by or on behalf of, the Indemnified Party or Indemnified Person. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action.

(d) The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or Indemnified Damages are incurred. Any Person receiving a payment pursuant to this Section 6 which person is later determined to not be entitled to such payment shall return such payment (including reimbursement of expenses) to the person making it.

(e) The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject to pursuant to the law.

To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however, that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds (net of all expenses paid by such holder in connection with any claim relating to this Section 7 and the amount of any damages such holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission) received by such seller from the sale of such Registrable Securities giving rise to such contribution obligation.

The Company shall not assign this Agreement or any rights or obligations hereunder (whether by operation of law or otherwise) without the prior written consent of the Investors holding a majority of the Registrable Securities then outstanding (determined as if all of the Pre-Funded Warrants then outstanding have been exercised in full without regard to any limitations on the exercise of such Pre-Funded Warrants) (voting together as a single class); provided, however, that in any transaction, whether by merger, reorganization, restructuring, consolidation, financing or otherwise, whereby the Company is a party and in which the Registrable Securities are converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term "Company" shall be deemed to refer to such Person and the term "Registrable Securities" shall be deemed to include the securities received by the Investor in connection with such transaction unless such securities are otherwise freely tradable by the Investor after giving effect to such transaction, and the prior written consent of the Investors holding a majority of the Registrable Securities then outstanding (determined as if all of the Pre-Funded Warrants then outstanding have been exercised in full without regard to any limitations on the exercise of such Pre-Funded Warrants) shall not be required for such transaction. No Investor may assign its rights under this Agreement, other than to an affiliate of such Investor or to any other investment funds or accounts managed or advised by the investment manager who acts on behalf of the Investor, without the prior written consent of the Company. The provisions of this Agreement shall be binding upon and inure to the benefit of the Investor and its successors and permitted assigns.

11

The provisions of this Agreement, including the provisions of this sentence, may be amended, modified or supplemented, or waived only by a written instrument executed by (a) the Company and (b) the holders of a majority of the then outstanding Registrable Securities (determined as if all of the Pre-Funded Warrants then outstanding have been exercised in full without regard to any limitations on the exercise of such Pre-Funded Warrants) (voting together as a single class), provided that (i) any party may give a waiver as to itself, (ii) any amendment, modification, supplement or waiver that disproportionately and adversely affects the rights and obligations of any Investor relative to the comparable rights and obligations of the other Investors shall require the prior written consent of such adversely affected Investor or each Investor, as applicable, and (iii) any amendments to Section 6 or to the definitions of "Filing Deadline," "Effectiveness Deadline," or "Registration Period" shall require the written consent of each Investor. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of one or more Investors and that does not adversely directly or indirectly affect the rights of other Investors may be given by Investors holding a majority of the Registrable Securities (determined as if all of the Pre-Funded Warrants then outstanding have been exercised in full without regard to any limitations on the exercise of such Pre-Funded Warrants) to which such waiver or consent relates.

(a) Notices. Any notices or other communications required or permitted to be given hereunder shall be in writing and shall be deemed to be given (a) when delivered if personally delivered to the party for whom it is intended, (b) when delivered, if sent by electronic mail during normal business hours of the recipient, and if not sent during normal business hours, then on the recipient's next business day, provided no rejection or undeliverable notice is received, (c) three (3) days after having been sent by certified or registered mail, return-receipt requested and postage prepaid, or (d) one (1) business day after deposit with a nationally recognized overnight courier, freight prepaid, specifying next business day delivery, with written verification of receipt:
