To the Dealers appointed

Terms Agreement or Appointment Agreement

under the Global Debt Program of the

Inter-American Development Bank

Ladies and Gentlemen:

Reference is made to the proceedings of the Inter-American Development Bank (the "Bank") to establish the Global Debt Program of the Bank, as it may be amended, restated, or superseded from time to time (the "Program"), and to authorize the issue and sale of Notes thereunder (the "Notes") with reference to a Prospectus dated July 28, 2020 (as supplemented and amended from time to time, the "Prospectus"). In connection with such proceedings, I have examined, among other documents, the following:

Pursuant to Section 5(e)(ii) of the Standard Provisions, I am of the opinion that:

While I assume no responsibility with respect to the statements in the Prospectus, nothing has come to my attention which has caused me to believe that the Prospectus, as of its date and as of the date hereof, and excluding the financial statements or other financial data, contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

This letter does not relate to the financial statements or other financial data contained in the Prospectus.

In rendering the foregoing opinion, I have relied, with respect to matters of New York law, upon the opinion of Sullivan & Cromwell LLP and, with respect to matters of English law, upon the opinion of Linklaters LLP, each delivered on the date hereof in accordance with the Standard Provisions. Also, I have assumed that signatures on all documents examined by me are genuine.

This letter is furnished by me as Chief Counsel (Corporate Legal Affairs Division) of the Bank to Dealers appointed from time to time under the Program and is solely for their benefit.

General Information

Additional Information Regarding the Notes.

"Use of Proceeds" in the Prospectus shall be deleted in its entirety and replaced by the following:

The Notes are issued under the Bank's Sustainable Debt Framework ("SDF") (available at https://publications.iadb.org/en/sustainable-debt-framework). As such, an amount equal to the net proceeds of the issue of the Notes (which proceeds may be converted into other currencies) shall be recorded by the Bank in a separate sub-account supporting Eligible Projects (as defined below). These proceeds will be invested in accordance with the Bank's conservative liquidity investment guidelines until used to support the Bank's financing of Eligible Projects. So long as the Notes are outstanding and the account has a positive balance, the Bank shall direct an amount equal to such net proceeds to its lending supporting Eligible Projects.

The Bank's Eligible Green and Social Projects ("Eligible Projects") are defined as investments and expenditures made by the Bank after the issuance of bonds under the SDF, or in the 36 months prior to any such issuance, within the eligible categories defined in the SDF. In addition, the Bank may issue bonds under the SDF to finance Eligible Projects in the Amazonia biome in accordance with the Bank's Amazonia Bond Issuance Guidelines.

Examples of Eligible Projects include, without limitation:

PRICING SUPPLEMENT

Inter-American Development Bank Global Debt Program Series No.:1014

U.S.$100,000,000 3.802 percent Notes due November 12, 2030

The above examples are for illustrative purposes only and no assurance can be provided that disbursements for projects with these specific characteristics will be made by the Bank during the term of the Notes.

Eligible Projects financed or refinanced through the Notes will be selected based on their alignment with the SDF and their environmental and social strong outcomes and impact metrics. The Treasury division, in collaboration with Office of Strategic Planning and Development Effectiveness and through consultations with lending specialists, selects Eligible Projects for allocation under the SDF. This selection shall include new projects, as well as existing projects including re-financing.

The Bank shall produce an annual Allocation and Impact report until full allocation of the proceeds that will be made available on the Bank Investor Website. In the event that projects are no longer in compliance with the eligibility criteria set forth in the SDF, the Bank commits to reallocating the proceeds to other eligible loans. The report will address, among other things, the outstanding balance of debt instruments issued under the SDF (including the Notes), the list of Eligible Projects, the amount of net proceeds that have been allocated to Eligible Projects, and the remaining balance of unallocated proceeds, if applicable.

Information on the Bank's website, including the SDF, is not intended to be incorporated by reference into this Pricing Supplement.

Although the Notes are issued under the SDF, the Notes may not satisfy an investor's requirements if the investor seeks to invest in assets with certain sustainability characteristics. No assurance is or can be given to investors that the use of proceeds will satisfy, whether in whole or in part, any present or future investor expectations or requirements regarding any investment criteria or guidelines applicable to any investor or its investments. In addition, no assurance is or can be given to investors that any projects undertaken by the Bank will meet any or all investor expectations regarding "sustainable" or other equivalently-labelled performance objectives or that any adverse environmental, social and/or other impacts will not occur during the implementation by the borrower or any other implementing entity of any projects. Furthermore, it should be noted that there is currently no clearly-defined definition (legal, regulatory or otherwise) of, nor market consensus as to what constitutes, a "sustainable" or an equivalently-labelled project or as to what precise attributes are required for a particular project to be defined as "sustainable" or such other equivalent label and if developed in the future, the Notes may not comply with any such definition or label.

There can be no assurance that the net proceeds from the sale of any particular tranche of Notes will be totally or partially disbursed for any Eligible Projects undertaken by the Bank within the term of such Notes or allocated to any expenditures for Eligible Projects in the 36 months prior to any such issuance. Not all projects undertaken by the Bank, including Eligible Projects, will be completed within the specified period or with the results or outcome as originally expected or anticipated by the Bank and some planned projects might not be completed at all. Each potential purchaser of the Notes should determine for itself the relevance of the information contained in this Pricing Supplement regarding the use of proceeds and its purchase of the Notes should be based upon such investigation as it deems necessary.

The Bank does not fall under the scope of application of either the MiFID II or the UK MiFIR regime. Consequently, the Bank does not qualify as an "investment firm", "manufacturer" or "distributor" for the purposes of MiFID II or UK MiFIR.

MiFID II product governance / Professional investors and ECPs target market - Solely for the purposes of the EU manufacturer's product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible counterparties and professional clients, each as defined in MiFID II; and (ii) all channels for distribution of the Notes are appropriate. Any person subsequently offering, selling or recommending the Notes (a "distributor") should take into consideration the EU manufacturer's target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the EU manufacturer's target market assessment) and determining appropriate distribution channels.

For the purposes of this provision, the expression "EU manufacturer" means the Dealer and the expression "MiFID II" means Directive 2014/65/EU, as amended.

UK MiFIR product governance / Professional investors and ECPs target market - Solely for the purposes of the UK manufacturer's product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible counterparties, as defined in COBS, and professional clients, as defined in UK MiFIR; and (ii) all channels for distribution of the Notes are appropriate. Any person subsequently offering, selling or recommending the Notes (a "distributor") should take into consideration the UK manufacturer's target market assessment; however, a distributor subject to the UK MiFIR Product Governance Rules is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the UK manufacturer's target market assessment) and determining appropriate distribution channels. For the purposes of this provision, (i) the expression "UK manufacturer" means the Dealer, (ii) the expression "COBS" means the FCA Handbook Conduct of Business Sourcebook, (iii) the expression "UK MiFIR" means Regulation (EU) No 600/2014 as it forms part of UK domestic law by virtue of the EUWA and (iv) the expression "UK MiFIR Product Governance Rules" means the FCA Handbook Product Intervention and Product Governance Sourcebook.
