This Amendment No. 1 ("Amendment No. 1") amends and supplements the Schedule 13D as originally filed by Credit Suisse First Boston, on behalf of the investment banking business of the Credit Suisse First Boston business unit, (the "Reporting Person") on September 30, 2002 (as so amended, the "Schedule 13D"). All share numbers referenced in this Amendment No. 1 reflect the Issuer's 10-to-1 reverse stock split effected on November 13, 2002. Capitalized terms used in this Amendment No. 1 but not defined have the respective meanings ascribed to them in the Schedule 13D.

The tables of the Schedule 13D are amended and restated in their entirety as set forth in this Amendment No. 1.

Item 2 of the Schedule 13D, "Identity and Background," is amended by adding the following:

The name, business address, citizenship and title of each executive officer or director of the Reporting Person, CSFBI, CSFB-USA and those CSFB Entities that are corporations are set forth on Schedule A-1 through A-6 attached hereto.

Item 3 of the Schedule 13D, "Source and Amount of Funds or Other Consideration," is amended by adding the following:

At the closing of the PIPES Agreement, as amended (the "Amended PIPES Agreement"), on November 19, 2002 (the "PIPES Closing" or the "PIPES Closing Date"), the Reporting Person purchased for cash consideration of $16,300,000 (a) 4,289,472 shares of Common Stock (the "Sprout PIPES Shares") and (b) five year warrants that are immediately exercisable and may be exercised in whole or in part at any time and from time-to-time to purchase 643,421 shares of Common Stock (the "Sprout PIPES Warrants" and together with the Sprout PIPES Shares, the "Sprout PIPES Securities") at a price per share of Common Stock of $3.80.

At the PIPES Closing, the Reporting Person also converted Senior Secured Promissory Notes of the Issuer with a face value of $700,000 into Common Stock at a conversion price of $3.80 per share of Common Stock. Such notes were purchased by the Reporting Person on September 19, 2002.

The funds used by the Reporting Person to acquire the Sprout PIPES Securities were not borrowed and were obtained from capital contributions by its partners and from direct capital commitments by DLJSC and DLJCC.

References to and descriptions of the Amended PIPES Agreement as set forth in this Item 3 are qualified in their entirety by reference to the PIPES Agreement, the Form of Warrant issued under the Amended PIPES Agreement and the Amendment to the PIPES Agreement included as Exhibits D, E and F, respectively, to the Schedule 13D, which agreements are incorporated in their entirety in this Item 3.

Item 4 of the Schedule 13D, "Purpose of Transaction" is amended by adding the following:

The Reporting Person purchased the Sprout PIPES Securities for investment purposes and, through representation on the Issuer's board of directors, intends to influence the management policies and control of the Issuer with the aim of increasing the value of the Issuer and the Reporting Person's investments. The Reporting Person retains the right to change its investment intent.

Pursuant to the Amended PIPES Agreement, Kathleen LaPorte, a Managing Director of DLJCC, and Peter Hutt, an attorney, were appointed to the board of directors of the Issuer as the "Sprout Designees" (as defined in the Amended PIPES Agreement) on the PIPES Closing Date.

Pursuant to the Amended PIPES Agreement, for so long as the funds managed or advised by the Sprout Group hold at least 1,100,000 shares of Common Stock (as adjusted by stock split, reverse stock split, dividend, reorganization, recapitalization or otherwise) purchased pursuant to the Amended PIPES Agreement, the Issuer agreed to use its best efforts to cause (i) two people designated by the Sprout Group (the "Sprout Designees") to be nominated and elected to the board of directors of the

Issuer in any election of directors, and (ii) if any of the Sprout Designees who has been elected to the board of directors of the Issuer shall cease for any reason to be a member of the board of directors of the Issuer during such person's term as a director, then the Issuer has agreed to use its best efforts, subject to applicable laws and regulations, to cause such vacancy to be filled by a replacement designated by the Sprout Group. For so long as the funds managed or advised by the Sprout Group hold at least 550,000 shares of Common Stock (as adjusted by stock split, reverse stock split, dividend, reorganization, recapitalization or otherwise) purchased pursuant to the Amended PIPES Agreement, the Issuer has agreed to use its best efforts to cause (i) one of the Sprout Designees to be nominated and elected to the board of directors of the Issuer in any election of directors, and (ii) if the Sprout Designee who has been elected to the board of directors of the Issuer shall cease for any reason to be a member of the board of directors of the Issuer during such person's term as a director, then the Issuer has agreed to use its best efforts, subject to applicable laws and regulations, to cause such vacancy to be filled by a replacement designated by the Sprout Group. For so long as any Sprout Designee remains a member of the board of directors, the Issuer has agreed that the compensation committee, the nominating committee and any committee that exercises substantial control over the Issuer or its operations will include a Sprout Designee.

Pursuant to the Amended PIPES Agreement, George M. Lasezkay, Wayne I. Roe, Benjamin F. McGraw III and John H. Parrish resigned from the board of directors of the Issuer on the PIPES Closing Date.

Pursuant to the Amended PIPES Agreement, the Issuer amended its certificate of incorporation on November 12, 2002 to effect a reverse stock split of the Common Stock whereby the Issuer issued one new share of common stock in exchange for 10 shares of its outstanding Common Stock.

Pursuant to the Amended PIPES Agreement, the Issuer amended its bylaws at the PIPES Closing to provide the following:

(1) The Issuer's board of directors will have nine members.

(2) The Issuer's board of directors shall have an audit committee, the composition and duties of which shall be in compliance with all applicable federal and state securities laws and the rules and regulations adopted by the National Association of Securities Dealers, Inc. concerning Nasdaq listed companies (the "NASD Rules"), and which shall consist of three members of the board of directors.

(3) The Issuer's board of directors shall have a nominating committee, the composition and duties of which shall be in compliance with all applicable federal and state securities laws and NASD Rules, and which shall consist of three members of the board of directors. The duties of the Issuer's nominating committee will include recommending to the board of directors for approval the hiring and termination of any executive officer of the Issuer, including the Chief Executive Officer and Chief Financial Officer, and nominating any new member of the board of directors.

(4) The Issuer's board of directors shall have a compensation committee, the composition and duties of which shall be in compliance with all applicable federal and state securities laws and NASD Rules, and which shall consist of three members of the board of directors. The duties of the Issuer's compensation committee will include authorizing the compensation of any executive officer, setting number of shares reserved for issuance under the Issuer's stock incentive plans, and setting employee compensation guidelines.

(5) After the closing of the Amended PIPES Agreement, the Issuer will not, without the approval of a majority of the total number of directors then in office:

(a) authorize, offer, sell, or issue any equity or debt securities of the Issuer or any of its subsidiaries.

(b) incur indebtedness for borrowed money or guarantee or act as a surety for any debt which individually or in the aggregate is in excess of $1,000,000.

(c) grant a security interest in assets of the Issuer or any of its subsidiaries which individually or in the aggregate secures an obligation having a value in excess of $500,000.

(e) purchase, license or otherwise acquire any of the rights, title or interest in any material intellectual property of any third party relating to pharmaceuticals or biologics.

(vi) approve any annual business plan or budget or any material revisions thereto.

(vii) hire or terminate any executive officer of the Issuer, including its Chief Executive Officer and Chief Financial Officer.

Re: ISTA Pharmaceuticals, Inc.—Lockup Agreement

Ladies and Gentlemen:

The undersigned understands that ISTA Pharmaceuticals, Inc., a Delaware corporation (the "Company"), has entered into the Common Stock and Warrant Purchase Agreement, dated as of September 19, 2002 (the "Purchase Agreement"), with the investors listed on Exhibit A thereto (the "Investors"), pursuant to which the Company has agreed, subject to the terms and conditions of the Purchase Agreement, to issue and sell to the Investors, and the Investors have agreed to purchase from the Company, shares of the Company's Common Stock and warrants to purchase Common Stock (the "PIPE Financing"). The undersigned further understands that the Company has agreed to use its reasonable efforts to enter into this letter agreement with the undersigned (the "Lockup Agreement") as a condition to consummating the PIPE Financing.

In order to induce the Investors to consummate the PIPE Financing, and in consideration of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the "Closing Date," as that term is defined in the Purchase Agreement, and continuing to and including the date 180 days after such Closing Date (the "Lockup Period"), the undersigned will not, directly or indirectly, offer, sell, contract to sell, pledge, grant any call option or purchase any put option with respect to, make any short sale or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the Securities and Exchange Commission (collectively the "Undersigned's Shares").

The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned's Shares even if such shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned's Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such shares.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned's Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any distributee of the undersigned, provided that such distributee agrees to be bound in writing by the restrictions set forth herein, (iii) to an "Affiliate" of the undersigned, as such term is defined in the Purchase Agreement, provided that such Affiliate agrees to be bound in writing by the restrictions set forth herein, or (iv) with the prior written consent of the Company. The undersigned now has, and, except as contemplated by clause (i), (ii), (iii), or (iv) above, for the duration of the Lockup Period will have, good and marketable title to the Undersigned's Shares, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company's transfer agent and registrar against the transfer of the Undersigned's Shares except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Investors are relying upon this Lockup Agreement in proceeding toward consummation of the PIPE Financing. The undersigned further

understands that this Lockup Agreement is irrevocable and shall be binding upon the undersigned's heirs, legal representatives, successors, and assigns.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this letter agreement and that this letter agreement constitutes the legal, valid and binding obligation of the undersigned.

This Lockup Agreement shall terminate and be of no further force and effect on January 1, 2003, if the Closing Date to the PIPE Financing has not occurred by such date.
