PRELIMINARY PROSPECTUS

SUBJECT TO COMPLETION

DATED December 17, 2025

INVO Fertility, Inc.

Up to 7,372,122 Shares of Common Stock

This prospectus relates to the offer and sale of up to an aggregate of 7,372,122 shares (the "Shares") of common stock of INVO Fertility, Inc. ("we," "us," "our," or the "Company"), par value $0.0001 per share (the "Common Stock"), consisting of (A) up to 153,187 shares (the "Conversion Shares") of Common Stock issuable upon conversion of our outstanding Series C-2 Non-Voting Convertible Preferred Stock (the "Series C-2 Preferred") held by Five Narrow Lane LP ("FNL"), (B) up to 118,343 shares (the "Placement Agent Warrant Shares") of Common Stock issuable upon exercise of a common stock purchase warrant (the "Placement Agent Warrant") issued to Maxim Partners LLC ("Maxim Partners") pursuant to a Placement Agency Agreement, by and among us and Maxim Group, LLC ("Maxim"), an affiliate of Maxim Partners, dated December 2, 2025, pursuant to which Maxim acted as placement agent for the Private Placement (as defined below),and (C) up to 7,100,592 shares of Common Stock, consisting of (i) up to 235,000 shares (the "Issued Shares") of Common Stock, (ii) up to 2,131,864 shares (the "Pre-Funded Warrant Shares") of Common Stock issuable upon exercise of a pre-funded warrant (the "Pre-Funded Warrant") to purchase shares of Common Stock, and (iii) up to 4,733,728 shares (the "Common Warrant Shares", together with the Placement Agent Warrant Shares and the Pre-Funded Warrant Shares, the "Warrant Shares") of Common Stock issuable upon exercise of a warrant (the "Common Warrant", together with the Placement Agent Warrant and the Pre-Funded Warrant, the "Warrants") to purchase shares of Common Stock. The Issued Shares, the Common Warrant, and the Pre-Funded Warrant were purchased by Armistice Capital Master Fund Ltd. ("Armistice") in a private placement transaction (the "Private Placement") pursuant to a Securities Purchase Agreement, by and between us and Armistice, dated December 2, 2025 (the "Securities Purchase Agreement"). The Prefunded Warrant will entitle the holder to purchase one share of Common Stock at an exercise price of $0.0001 per share, the Common Warrant will entitle the holder to purchase one share of Common Stock at an exercise price of $1.69 per share, and the Placement Agent Warrant will entitled the holder to purchase one share of Common Stock at an exercise price of $2.1125 per share. The holders of the Warrants and the underlying Warrant Shares and the outstanding shares of Series C-2 Preferred and the underlying Conversion Shares are each referred to herein as a "Selling Stockholder" and collectively as the "Selling Stockholders."

For purposes of this prospectus, we have assumed (i) exercise prices under the Prefunded Warrant, Common Warrant, and the Placement Warrant of $0.0001 per share, $1.69 per share, and $2.115 per share of Common Stock, respectively, and (ii) a conversion price at the Floor Price (as defined in that certain Certificate of Amendment to the Certificate of Designations of the Series C-2 Preferred (the "Series C-2 Certificate of Designations"), which currently set at $4.896 per share of Common Stock.

The Selling Stockholders may sell or otherwise dispose of the Shares described in this prospectus in a number of different ways and at varying prices, which may be determined by the prevailing market price for the Common Stock or in negotiated transactions. We are not selling any shares of Common Stock under this prospectus and will not receive any of the proceeds from the sale or other disposition of the Shares by the Selling Stockholder. However, we may receive up to $8,250,213.0975 upon the exercise of the Warrants. All expenses of registration incurred in connection with this offering are being borne by us. All selling and other expenses incurred by the Selling Stockholder will be borne by the Selling Stockholder. The Issued Shares, the Warrants, the Warrant Shares, the Series C-2 Preferred, and the Conversion Shares were each issued to the applicable Selling Stockholders in connection with private placement offerings pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), and/or Regulation D promulgated thereunder.

This prospectus describes the manner in which the Shares may be sold or otherwise disposed of by the Selling Stockholders. You should carefully read this prospectus, as well as the documents incorporated by reference or deemed to be incorporated by reference into this prospectus, carefully before you invest. See "Plan of Distribution" for additional information regarding the sale or other disposition by the Selling Stockholders of the Shares.

Our Common Stock is listed on the Nasdaq Capital Market ("Nasdaq") under the symbol "IVF". The last reported sale price for our Common Stock as reported on Nasdaq on December 16, 2025 was $1.18 per share.

INDUSTRY AND MARKET DATA

Unless otherwise indicated, information contained in this prospectus concerning the Company's industry and the markets in which it operates, including market position and market opportunity, is based on information from management's estimates, as well as from industry publications and research, surveys and studies conducted by third parties. The third-party sources from which the Company has obtained information generally state that the information contained therein has been obtained from sources believed to be reliable, but the Company cannot assure you that this information is accurate or complete. The Company has not independently verified any of the data from third-party sources nor has it verified the underlying economic assumptions relied upon by those third parties.

Management estimates are derived from publicly available information, its knowledge of the industry, and assumptions based on such information and knowledge, which management believes to be reasonable and appropriate. However, assumptions and estimates of the Company's future performance, and the future performance of its industry, are subject to numerous known and unknown risks and uncertainties, including those described under the heading "Risk Factors" in this prospectus and those described elsewhere in this prospectus, and the other documents the Company files with the Securities and Exchange Commission, or SEC, from time to time. These and other important factors could result in its estimates and assumptions being materially different from future results. You should read the information contained in this prospectus completely and with the understanding that future results may be materially different and worse from what the Company expects. See the information included under the heading "Special Note Regarding Forward-Looking Statements."

You should read the entire prospectus carefully, including the matters set forth under "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations," our financial statements, and related notes included elsewhere in this prospectus and the information incorporated into this prospectus by reference. In this prospectus, unless context requires otherwise, references to "we," "us," "our," "INVO Fertility," "INVO," or "the Company" refer to INVO Fertility, Inc. and its subsidiaries.

The Company

We are a healthcare services and technology company focused on the fertility marketplace and dedicated to expanding access to assisted reproductive technology ("ART") care for patients in need. Our principal commercial strategy is focused on building, acquiring, and operating fertility clinics, including "INVO Centers" dedicated primarily to offering the intravaginal culture ("IVC") procedure enabled by our INVOcell® medical device ("INVOcell") and US-based, profitable in vitro fertilization ("IVF") clinics. We have two operational INVO Centers and one IVF clinic in the United States. We also continue to engage in the sale and distribution of our INVOcell technology solution into third-party owned and operated fertility clinics and intend to seek out additional, innovative fertility-focused technologies to license or acquire in order to utilize within our clinics.

In October 2024, we acquired a 100% interest in NAYA Therapeutics, Inc. ("NAYA Therapeutics" or "NTI"), a clinical-stage oncology and autoimmune technology company. In May 2025, we divested an 80.1% ownership interest in NTI, returning to an exclusive focus on the fertility marketplace, and changed our name and ticker symbol to "INVO Fertility, Inc." and "IVF", respectively.

Fertility Clinics

On August 10, 2023, we consummated the first acquisition of an existing IVF clinic, the Wisconsin Fertility Institute ("WFI"). As an established and profitable clinic, the consummation of the WFI acquisition more than tripled our annual revenue and became a major part of our clinic-based operations. The acquisition accelerated our expansion from a medical device company to a healthcare services company and immediately added scale and a significant source of positive cash flow to our operations. The acquisition of profitable IVF clinics complements our efforts to build new INVO Centers, and we expect to continue this strategy to accelerate overall growth.

On March 10 and June 28, 2021, we established joint ventures to open INVO Centers in Birmingham, Alabama, and Atlanta, Georgia, respectively. We established these clinics to increase use of the INVOcell, to accelerate the growth and awareness of the IVC procedure and to expand the availability of statistical data supporting its use. These clinics also enabled us to expand our revenue per fertility cycle from hundreds of dollars (from the sale of each INVOcell device) to thousands of dollars, and to significantly advance our path to profitability. We believe dedicated INVO Centers require less investment than traditional IVF clinics and are operationally efficient, making them ideal for underserved secondary markets. We plan on opening additional wholly owned INVO Centers in the coming years.

INVOcell Device

Our proprietary technology, INVOcell®, is an innovative medical device that allows fertilization and early embryo development to take place in vivo within the woman's body. This treatment solution is the world's first intravaginal culture technique for the incubation of oocytes and sperm during fertilization and early embryo development and provides patients with a connected, intimate, and affordable experience. As reflected in available data, we believe the IVC procedure can deliver comparable results at a lower cost than traditional IVF and is a significantly more effective treatment than intrauterine insemination ("IUI").

Unlike IVF, where the oocytes and sperm develop into embryos in an expensive laboratory incubator, the INVOcell allows fertilization and early embryo development to take place in the woman's body. The IVC procedure can provide many benefits, including the following:

	●	May reduce lab procedures, helping clinics and doctors to increase patient capacity, lower costs and offer a more affordable advanced fertility treatment option;
	●	Provide a more natural, stable incubation environment;
	●	Offer a more personal, intimate experience in creating a baby; and
	●	Reduce the risk of errors in the lab.

In both current utilization of the INVOcell, and in clinical studies, the IVC procedure has demonstrated equivalent pregnancy success and live birth rates as IVF.

While INVOcell remains part of our efforts, our commercial and corporate development strategy within the fertility market has expanded to focus more broadly on providing ART services through our emphasis on operating clinics. However, we will continue to provide INVOcell as well as seek out additional, innovative technologies, we can utilize to benefit patients and enhance our clinic operations.

Certain Recent Developments

On December 12, 2025, we, through our wholly owned subsidiary, INVO Centers LLC, a Delaware limited liability company ("INVO Centers LLC"), entered into an asset purchase agreement (the "Asset Purchase Agreement"), by and among INVO Centers LLC, Family Beginnings, P.C., an Indiana professional service corporation ("Family Beginnings"), and James Donahue, MD ("Dr. Donahue"), to acquire Family Beginnings for a combined purchase price of $750,000 (the "Purchase Price"). Pursuant to the Asset Purchase Agreement, among other things, (i) Family Beginnings agreed to sell, and INVO Centers LLC agreed to purchase, all non-clinical Assets (as defined in the Asset Purchase Agreement) of Family Beginnings at Closing (as defined below) and (ii) INVO Centers LLC agreed to deliver to Family Beginnings the Purchase Price at Closing, which consists of (I) $350,000 less a holdback amount of $150,000 and (II) 4,000 shares of our preferred stock to be designated as "Series D Non-Voting Convertible Preferred Stock" for a total stated value equal to Four Hundred Thousand Dollars ($400,000).

Family Beginnings owns, operates and manages a fertility practice in Indianapolis, Indiana (the "Clinic") that provides direct treatment to patients primarily focused on fertility procedures and employs a physician and other healthcare providers to deliver such treatments and procedures. Family Beginnings is currently wholly owned by Dr Donahue, who acts as the Clinic's primary physician, medical director and lab director. The Clinic offers a suite of reproductive services, including the following:

	●	IVF;
	●	IVC;
	●	IUI;
	●	Third-party reproduction services;
	●	Fertility preservation;
	●	Advanced diagnostic testing; and
	●	Comprehensive patient education and support programs

The closing (the "Closing") of the acquisition is expected to occur by February 27, 2026. Pursuant to the Asset Purchase Agreement, (a) should the Closing not occur by February 27, 2026, the Asset Purchase Agreement shall automatically terminate, unless INVO Centers, LLC and Family Beginnings agree to extend the time to Closing past February 27, 2026, and (b) should the Closing occur after January 31, 2026, the cash portion of the Purchase Price shall be increased by $10,000.

RISK FACTORS

An investment in the securities offered under this prospectus involves a high degree of risk. You should carefully consider and evaluate all of the information contained in this prospectus and in the documents that we incorporate by reference herein before you decide to invest in our securities. In particular, you should carefully consider and evaluate the risks and uncertainties described below, as well as those set forth under the heading "Risk Factors" in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, which are incorporated by reference in this prospectus. Our business, financial condition, or results of operations could be materially and adversely affected by any of these risks and uncertainties. Investors are further advised that the risks described below may not be the only risks we face. Additional risks that we do not yet know of, or that we currently think are immaterial, may also negatively impact our business operations or financial results. Any of the risks and uncertainties set forth in this prospectus and in the documents incorporated by reference herein, as updated by annual, quarterly, and other reports and documents that we file with the SEC and incorporate by reference into this prospectus, could materially and adversely affect our business, results of operations, and financial condition, which in turn could materially and adversely affect the value of our securities.

Risks Related to this Offering

The Selling Stockholder may choose to sell the shares at prices below the current market price.

The Selling Stockholder is not restricted as to the prices at which it may sell or otherwise dispose of the Shares covered by this prospectus. Sales or other dispositions of the Shares below the then-current market prices could adversely affect the market price of our Common Stock.

Neither we nor the Selling Stockholder has authorized any other party to provide you with information concerning us or this offering.

You should carefully evaluate all of the information in this prospectus, including the documents incorporated by reference herein. We may receive media coverage regarding our Company, including coverage that is not directly attributable to statements made by our officers, that incorrectly reports on statements made by our officers or employees, or that is misleading as a result of omitting information provided by us, our officers or employees. Neither we nor the Selling Stockholder has authorized any other party to provide you with information concerning us or this offering, and recipients should not rely on this information.

It is not possible to predict the actual number of shares of Series C-2 Preferred we will sell under an Additional Investment Right to the Selling Stockholder, or the actual gross proceeds resulting from those sales.

Subject to that certain securities purchase agreement (as amended, the "January 2024 Securities Purchase Agreement"), dated as of January 3, 2024, between FNL and NAYA Therapeutics Inc., to which the Company became a party pursuant to a joinder agreement (the "Joinder Agreement") on October 11, 2024 and compliance with applicable law, for so long as shares of Series C-2 Preferred are outstanding, FNL shall have the right (the "Additional Investment Right") to purchase up to $10 million of aggregate stated value of additional shares of Series C-2 Preferred (the "AIR Preferred Shares"), provided that any Additional Investment Right may only be exercised in a minimum amount of $200,000 of AIR Preferred Shares. The actual number of AIR Preferred Shares that are sold to FNL may depend based on a number of factors, including the market price of the Common Stock during the sales period. Actual gross proceeds may be less than $10 million, which may impact our future liquidity. Moreover, upon issuance of AIR Preferred Shares, the conversion price in the AIR Preferred Shares and Series C-2 Preferred shall be deemed to be the lowest of (i) the conversion price as in effect on the date that the Holder exercises such Additional Investment Right, and (ii) the greater of (x) the Floor Price (as defined in that certain Certificate of Amendment to the Certificate of Designations of the Series C-2 Preferred (the "Series C-2 Certificate of Designations"), currently set at $4.896 per share) and (y) 85% of the arithmetic average of the three (3) lowest VWAPs during the ten (10) trading days prior to the date FNL exercises its Additional Investment Right. Because the conversion price per share of the Series C-2 Preferred is subject to reduction during the sales period, it is not currently possible to predict the number of Shares that will be sold.

Investors who buy shares at different times will likely pay different prices.

Investors who purchase Shares in this offering at different times will likely pay different prices and so may experience different levels of dilution and different outcomes in their investment results. Pursuant to the terms of the Additional Investment Right, FNL will have discretion to vary the timing, prices, and numbers of AIR Shares it purchases. Similarly, the Selling Stockholders may sell shares of Common Stock underlying the Series C-2 Preferred and the Warrants at different times and at different prices. Investors may experience a decline in the value of the Shares they purchase from the Selling Stockholders in this offering as a result of sales of Series C-2 Preferred made by us in future transactions to FNL with conversion prices lower than the prices they paid.

The issuance of Common Stock to the Selling Stockholders upon exercise of the Warrants and upon conversion of the Series C-2 Preferred may cause substantial dilution to our existing stockholders, and the sale of such shares acquired by the Selling Stockholder could cause the price of our Common Stock to decline.

We are registering for resale by the Selling Stockholder of up to 7,372,122 shares of Common Stock, including 7,137,122 shares of Common Stock that we may issue to the Selling Stockholders upon exercise or conversion, as applicable of the Warrants and the Series C-2 Preferred. The number of shares of our Common Stock ultimately offered for resale by the Selling Stockholders under this prospectus is dependent upon the number of shares of Common Stock issued to the Selling Stockholders upon exercise or conversion, as applicable, of the Warrants and Series C-2 Preferred. Depending on a variety of factors, including market liquidity of our Common Stock, the issuance of Shares to the Selling Stockholders may cause the trading price of our Common Stock to decline. Following receipt by the Selling Stockholders of Shares issued to the Selling Stockholders upon exercise or conversion, as applicable, of the Warrants and the Series C-2 Preferred, the Selling Stockholders may sell all, some or none of such Shares. The sale of a substantial number of shares of our Common Stock by the Selling Stockholders in this offering, or anticipation of such sales, could cause the trading price of our Common Stock to decline or make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise desire.

Our management will have broad discretion over the use of the net proceeds received upon exercise of the Warrants, you may not agree with how we use the proceeds, and the proceeds may not be invested successfully.

Our management will have broad discretion over the use of proceeds from the shares of Common Stock received upon exercise of the Warrants. We intend to use the net proceeds primarily for acquisitions of additional fertility clinics and related businesses, capital expenditures, working capital, and general and administrative expenses. The net proceeds, if any, may be used for corporate purposes that do not improve our operating results or enhance the value of our Common Stock. The failure of our management to use these funds effectively could have a material adverse effect on our business or cause the market price of our Common Stock to decline.

Risks Related to the Acquisition of Family Beginnings

We may not realize the benefits we anticipate from the Family Beginnings acquisition or be successful in integrating the operations, personnel, technology, or assets of Family Beginnings with our existing operations

We have not completed the acquisition of Family Beginnings, there are significant conditions to closing the acquisition, and, therefore, there is a possibility that the acquisition may not close as anticipated.

Further, the Family Beginnings acquisition may prove to be worth less than we paid. The acquisition may not produce revenues, earnings or cash flow at anticipated levels. We may be unable to integrate Family Beginnings successfully and realize anticipated economic, operational and other benefits in a timely manner, which could result in substantial costs and delays or other operational, technical or financial problems. We may also be unable to retain management and skilled and technically knowledgeable employees.

The Family Beginnings acquisition could disrupt our ongoing business, distract management, divert resources and make it difficult to maintain our current business standards, controls and procedures. The failure to successfully integrate Family Beginnings and to realize the benefits anticipate from the Family Beginnings acquisition could have a material adverse effect on our business or cause the market price of our Common Stock to decline.

Governmental actions could delay, condition, or prevent the completion of our acquisition and could adversely affect the anticipated benefits of the transaction.

Governmental authorities may delay, condition or prohibit the acquisition, or require us to comply with conditions, restrictions or remedial measures that could increase the cost of the transaction, limit our ability to operate the acquired business as anticipated, or reduce the expected benefits of the acquisition. Any potential regulatory review may take longer than expected or may not be obtained on acceptable terms, or at all.

In addition, changes in applicable laws, regulations, regulatory interpretations or enforcement priorities, or the initiation of investigations or legal proceedings by governmental authorities, could further delay or prevent the completion of the acquisition or impose additional obligations on us following the closing. Even if the acquisition is completed, we may be subject to ongoing regulatory requirements, increased compliance costs or operational restrictions applicable to the acquired business that differ from or are more burdensome than those applicable to our existing operations. If we are unable to obtain required approvals, satisfy regulatory conditions or effectively comply with post-closing regulatory requirements, the acquisition may not be completed as anticipated, or the expected benefits of the acquisition may not be realized, which could materially adversely affect our business, financial condition, and results of operations or cause the market price of our Common Stock to decline.

We will not receive any proceeds from the sale of Shares by the Selling Stockholder pursuant to this prospectus. However, we may receive aggregate gross proceeds of up to $8,056,233.87 upon the Selling Stockholder's exercise of the Common Warrant, the Pre-Funded Warrant, and the Placement Agent Warrant. We intend to use the net proceeds primarily for acquisitions of additional fertility clinics and related businesses, capital expenditures, working capital, and general and administrative expenses.

The AIR Preferred Shares shall have the same terms as the Series C-2 Preferred then outstanding, provided that, upon issuance of AIR Preferred Shares, the conversion price in the AIR Preferred Shares and Series C-2 Preferred shall be deemed to be the lowest of (i) the conversion price as in effect on the date that FNL exercises such Additional Investment Right, and (ii) the greater of (x) the Floor Price (as defined in the Certificate of Amendment to the Series C-2 Certificate of Designation) and (y) 85% of the arithmetic average of the three (3) lowest VWAPs during the ten (10) trading days prior to the date FNL exercises its Additional Investment Right.

Broker dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA Rule 2121.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The Selling Stockholders has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the securities.

The Company is required to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act.

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

Item 14. Indemnification of Officers and Directors.

We are a Nevada corporation and generally governed by the Nevada Private Corporations Code, Title 78 of the Nevada Revised Statutes (the "NRS").

Section 78.138 of the NRS provides that, unless the corporation's articles of incorporation provide otherwise, a director or officer will not be individually liable unless it is proven that (i) the director's or officer's acts or omissions constituted a breach of his or her fiduciary duties, and (ii) such breach involved intentional misconduct, fraud, or a knowing violation of the law. Our articles of incorporation provide the personal liability of our directors is eliminated to the fullest extent permitted under the NRS.

Section 78.7502 of the NRS permits a company to indemnify its directors and officers against expenses, judgments, fines, and amounts paid in settlement actually and reasonably incurred in connection with a threatened, pending, or completed action, suit, or proceeding, if the officer or director (i) is not liable pursuant to NRS 78.138, or (ii) acted in good faith and in a manner the officer or director reasonably believed to be in or not opposed to the best interests of the corporation and, if a criminal action or proceeding, had no reasonable cause to believe the conduct of the officer or director was unlawful. Section 78.7502 of the NRS requires a corporation to indemnify a director or officer that has been successful on the merits or otherwise in defense of any action or suit. Section 78.7502 of the NRS precludes indemnification by the corporation if the officer or director has been adjudged by a court of competent jurisdiction, after exhaustion of all appeals, to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court determines that in view of all the circumstances, the person is fairly and reasonably entitled to indemnity for such expenses and requires a corporation to indemnify its officers and directors if they have been successful on the merits or otherwise in defense of any claim, issue, or matter resulting from their service as a director or officer.

Section 78.751 of the NRS permits a Nevada company to indemnify its officers and directors against expenses incurred by them in defending a civil or criminal action, suit, or proceeding as they are incurred and in advance of final disposition thereof, upon determination by the stockholders, the disinterested board members, or by independent legal counsel. If so provided in the corporation's articles of incorporation, bylaws, or other agreement, Section 78.751 of the NRS requires a corporation to advance expenses as incurred upon receipt of an undertaking by or on behalf of the officer or director to repay the amount if it is ultimately determined by a court of competent jurisdiction that such officer or director is not entitled to be indemnified by the company. Section 78.751 of the NRS further permits the company to grant its directors and officers' additional rights of indemnification under its articles of incorporation, bylaws, or other agreement.

Section 78.752 of the NRS provides that a Nevada company may purchase and maintain insurance or make other financial arrangements on behalf of any person who is or was a director, officer, employee, or agent of the company, or is or was serving at the request of the company as a director, officer, employee, or agent of another company, partnership, joint venture, trust, or other enterprise, for any liability asserted against him and liability and expenses incurred by him in his capacity as a director, officer, employee, or agent, or arising out of his status as such, whether or not the company has the authority to indemnify him against such liability and expenses.

Our articles of incorporation provide for indemnification of our officers and directors to the fullest extent permissible under Nevada General Corporation Law, in accordance with the Company's Bylaws. Our Bylaws provide for indemnification of our officers and directors to the fullest extent not prohibited by the Nevada; provided however, that the Company may modify the extent of such indemnification by individual contracts with its directors and officers; and provided, further, that the Company shall not be required to indemnify any director or officer in connection with any proceeding (or part thereof) initiated by such person unless (i) such indemnification is expressly required to be made by law; (ii) the proceeding was authorized by the board of directors; (iii) such indemnification is provided by the Company, in its sole discretion, pursuant to the powers vested in the corporation under the Nevada General Corporation Law or; (iv) such indemnification is a result of the enforcement of a contractual right.

See "Item 17. Undertakings" for a description of the SEC's position regarding such indemnification provisions.

The list of exhibits in the Exhibit Index to this registration statement is incorporated herein by reference.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1)	To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

	(i)	To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;
	(ii)	To reflect in the prospectus any facts or events arising after the effective date of this registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of the securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and
	(iii)	To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement;

provided, however, that the undertakings set forth in paragraphs (1)(i), (1)(ii) and (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, that are incorporated by reference in this registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of this registration statement;

(2)	That, for the purpose of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;
(3)	To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;
(4)	That, for the purpose of determining liability under the Securities Act of 1933, as amended, to any purchaser:

	(i)	Each prospectus filed by the registrant pursuant to Rule 424 (b)(3) shall be deemed to be part of this registration statement as of the date the filed prospectus was deemed part of and included in this registration statement; and
	(ii)	Each prospectus required to be filed pursuant to Rule 424 (b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(l)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933, as amended, shall be deemed to be part of and included in the registration statement as of the earlier of the date such prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date;

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933, as amended, to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

	(ii)	Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
	(iii)	The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
	(iv)	Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser;

(6)	That, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;
(7)	Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, as amended, and will be governed by the final adjudication of such issue.
