ARTICLE I

THE OFFER AND THE MERGER

     SECTION 1.1 The Offer . (a) Subject to the conditions of this Agreement, as promptly as practicable but in no event later than the later of (x) six Business Days after the date of this Agreement and (y) the first Business Day following publication in the Federal Register of SEC Release Number 34-54684 relating to the amendments to Rule 14d-10 promulgated under the Exchange Act (the date of such publications referred to as the “ Publication Date ”), Merger Sub shall, and Parent shall cause Merger Sub to, commence the Offer within the meaning of the applicable rules and regulations of the Securities and Exchange Commission (the “ SEC ”). The obligations of Merger Sub to, and of Parent to cause Merger Sub to, commence the Offer and accept for payment, and pay for, any Shares tendered pursuant to the Offer are subject to the conditions set forth in Exhibit A. The initial expiration date of the Offer shall be midnight New York City time on the later of (x) the 30th day (or if such day is not a Business Day, the first Business Day thereafter) following the Publication Date and (y) the 20th Business Day following the commencement of the Offer (determined using Exchange Act Rule 14d-1(g)(3) of the SEC) (the initial “ Expiration Date ” and any expiration time and date established pursuant to an extension of the Offer as so extended, also an “ Expiration Date ”). Merger Sub expressly reserves the right (x) if the Minimum Tender Condition has not been satisfied or if an Adverse Recommendation Change has been made, to increase the Offer Price and (y) to waive any condition to the Offer or modify the terms of the Offer, except that, without the consent of the Company, Merger Sub shall not (i) reduce the number of Shares subject to the Offer, (ii) reduce the Offer Price, (iii) waive the Minimum Tender Condition (as defined in Exhibit A), (iv) add to the conditions set forth in Exhibit A or modify any condition set forth in Exhibit A in any manner adverse to the holders of Company Common Stock, (v) except as otherwise provided in this Section 1.1(a), extend the Offer, (vi) change the form of consideration payable in the Offer or (vii) otherwise amend the Offer in any manner adverse to the holders of Company Common Stock. Notwithstanding the foregoing, Merger Sub may, in its discretion, without the consent of the Company, (i) extend the Offer for one or more consecutive increments of not more than five Business Days each, if at any otherwise scheduled Expiration Date of the Offer any of the conditions to Merger Sub’s obligation to purchase Shares are not satisfied or waived, until such time as such conditions are satisfied or waived, (ii) extend the Offer for the minimum period required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer or (iii) make available a “subsequent offering period” in accordance with Exchange Act Rule 14d-11. In addition, if at any otherwise scheduled Expiration Date of the Offer any condition to the Offer is not satisfied or waived, Merger Sub shall, and Parent shall cause Merger Sub to, extend the Offer at the request of the Company for one or more consecutive increments of not more than five Business Days each. In addition, Merger Sub shall, if requested by the Company, make available a subsequent offering period in accordance with

Exchange Act Rule 14d-11 of not less than ten Business Days; provided that Merger Sub shall not be required to make available such a subsequent offering period in the event that, prior to the commencement of such subsequent offering period, Parent and Merger Sub, directly or indirectly own more than 80% of the Fully Diluted Shares. On the terms and subject to the conditions of the Offer and this Agreement, Merger Sub shall, and Parent shall cause Merger Sub to, accept and pay for all Shares validly tendered and not withdrawn pursuant to the Offer that Merger Sub becomes obligated to purchase pursuant to the Offer as soon as practicable after the expiration of the Offer. For the avoidance of doubt, the parties hereto agree that shares of Restricted Company Common Stock may be tendered in the Offer and be acquired by Parent or Merger Sub pursuant to the Offer.

     (b) On the date of commencement of the Offer, Parent and Merger Sub shall file with the SEC a Tender Offer Statement on Schedule TO with respect to the Offer, which shall contain an offer to purchase and a related letter of transmittal and summary advertisement (such Schedule TO and the documents included therein pursuant to which the Offer will be made, together with any supplements or amendments thereto, the “ Offer Documents ”). Each of Parent, Merger Sub and the Company shall promptly correct any information provided by it for use in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and each of Parent and Merger Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be filed with the SEC and the Offer Documents as so amended or supplemented to be disseminated to the Company’s shareholders, in each case as and to the extent required by applicable federal securities laws. Parent, Merger Sub and the Company will cooperate and consult with each other and their respective counsel in the preparation of the Offer Documents. Without limiting the generality of the foregoing, the Company will furnish to Parent the information relating to it required by the Exchange Act and the rules and regulations promulgated thereunder to be set forth in the Offer Documents. Parent and Merger Sub shall (i) provide the Company and its counsel in writing with any comments Parent, Merger Sub or their counsel may receive from the SEC or its staff with respect to the Offer Documents promptly after the receipt of such comments, (ii) consult with the Company and its counsel prior to responding to any such comments, and (iii) provide the Company and its counsel in writing with any comments or responses thereto of Parent, Merger Sub or their counsel. Parent and Merger Sub shall give the Company a reasonable opportunity to review and comment on the Offer Documents and any amendments thereto.

     (c) Parent shall provide or cause to be provided to Merger Sub on a timely basis the funds necessary to purchase any Shares that Merger Sub becomes obligated to purchase pursuant to the Offer.

     (d) The Company hereby grants to Parent and Merger Sub an irrevocable option (the “ Top-Up Option ”) to purchase at a price per share equal to the Offer Price up to that number of newly issued shares of the Company Common Stock (the “ Top-Up Shares ”) equal to the lowest number of shares of Company Common Stock that, when added to the number of shares of Company Common Stock, directly or indirectly, owned by Parent and Merger Sub at the time of exercise of the Top-Up Option shall constitute one share more than eighty percent (80%) of the Fully Diluted Shares immediately after the issuance of the Top-Up Share. The Top-Up Option shall be exercisable only once, at such time as Parent and Merger Sub, directly or

indirectly, own at least 70% of the Fully Diluted Shares and prior to the fifth Business Day after the Expiration Date or the expiration date of any subsequent offering period. Such Top-Up Option shall not be exercisable to the extent the number of shares of Company Common Stock subject thereto (taken together with the number of Fully Diluted Shares outstanding at such time) exceeds the number of authorized shares of Company Common Stock available for issuances. The obligation of the Company to deliver the Top-Up Shares upon the exercise of the Top-Up Option is subject to the condition that no provision of any applicable Law and no Judgment, injunction, order or decree shall prohibit the exercise of the Top-Up Option or the delivery of the Top-Up Shares in respect of such exercise. The parties shall cooperate to ensure that the issuance of the Top-Up Shares is accomplished consistent with all applicable legal requirements of all Governmental Entities, including compliance with an applicable exemption from registration of the Top-Up Shares under the Securities Act. In the event Parent and Merger Sub wish to exercise the Top-Up Option, Merger Sub shall give the Company one (1) Business Day prior written notice specifying the number of shares of the Company Common Stock that are or will be, directly or indirectly, owned by Parent and Merger Sub immediately preceding the purchase of the Top-Up Shares and specifying a place and a time for the closing of such purchase. The Company shall, as soon as practicable following receipt of such notice, deliver written notice to Merger Sub specifying the number of Top-Up Shares. At the closing of the purchase of Top-Up Shares, the portion of the purchase price owed by Parent or Merger Sub upon exercise of such Top-Up Option shall be paid to the Company (i) in cash by wire transfer or cashier’s check or (ii) by issuance by Merger Sub to the Company of a promissory note on terms reasonably satisfactory to the Company.

     SECTION 1.2 Company Actions . (a) The Company hereby approves of and consents to the Offer, the Merger and the other transactions contemplated by this Agreement.

     (b) On the date the Offer Documents are filed with the SEC or as soon as practicable thereafter, the Company shall file with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the Offer (such Schedule 14D-9, as amended from time to time, the “ Schedule 14D-9 ”) containing the recommendations referred to in Section 3.4(b) and shall mail the Schedule 14D-9 to the holders of Company Common Stock. Each of the Company, Parent and Merger Sub shall promptly correct any information provided by it for use in the Schedule 14D-9 if and to the extent that such information shall have become false or misleading in any material respect, and the Company shall take all steps necessary to amend or supplement the Schedule 14D-9 and to cause the Schedule 14D-9 as so amended or supplemented to be filed with the SEC and disseminated to the Company’s shareholders, in each case as and to the extent required by applicable federal securities laws. Parent, Merger Sub and the Company will cooperate and consult with each other and their respective counsel in the preparation of the Schedule 14D-9. Without limiting the generality of the foregoing, Parent will furnish to the Company the information relating to it required by the Exchange Act and the rules and regulations promulgated thereunder to be set forth in the Schedule 14D-9. The Company shall (i) provide Parent and its counsel in writing with any comments the Company or its counsel may receive from the SEC or its staff with respect to the Schedule 14D-9 promptly after the receipt of such comments, (ii) consult with Parent and Merger Sub and their counsel prior to responding to any such comments, and (iii) provide Parent and Merger Sub and their counsel in writing with any comments or responses thereto of the Company or its counsel. The Company

shall give Parent and Merger Sub a reasonable opportunity to review and comment on the Schedule 14D-9 and any amendments thereto.

     (a) subject to Section 2.3, each Share issued and outstanding immediately prior to the Effective Time (other than any Shares to be canceled pursuant to Section 2.1(b) or to be converted pursuant to Section 2.1(c), but including Shares subject to vesting or other restrictions (the “ Restricted Company Common Stock ”)) shall be converted into the right to receive the highest price per Share paid pursuant to the Offer in cash without interest (the “ Merger Consideration ”);

     (b) each Share held in the treasury of the Company and each Share owned by Parent or Merger Sub immediately prior to the Effective Time shall be canceled and retired without any conversion thereof, and no payment or distribution shall be made with respect thereto;

     (c) all of the Shares owned by Kos Investments, Inc. or Kos Holdings, Inc. immediately prior to the Effective Time shall be converted, in the aggregate, into a number of shares equal to the same percentage of the fully-diluted outstanding stock of the Surviving Corporation as such shares currently represent of the Fully Diluted Shares; and

     (d) each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into one share of common stock of the Surviving Corporation.

     Except as set forth in Sections 2.1(b) and (c), (i) at the Effective Time, all Shares of Company Common Stock shall cease to be outstanding, shall automatically be cancelled and shall cease to exist and (ii) each holder of a certificate that immediately prior to the Effective Time represented any such Shares of Company Common Stock (a “ Certificate ”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration.

     SECTION 2.2 Treatment of ESPP, Warrants, etc. (a) The Company shall take any and all actions with respect to the Company’s Employee Stock Purchase Plan (the “ ESPP ”) as are necessary to provide that, subject to consummation of the Merger, the ESPP shall terminate, effective on the date immediately prior to the Closing Date (the “ ESPP Termination Date ”). On the ESPP Termination Date, each purchase right under the ESPP as of the ESPP Termination Date shall be automatically exercised by applying the payroll deductions of each participant in the ESPP for the applicable Offering Period (as defined in the ESPP) to the purchase of a number of whole Shares (subject to the provisions of the ESPP regarding the number of shares purchasable) at the exercise price per Share specified in the ESPP, which number of shares will then be canceled and converted into the right to receive the Merger Consideration in accordance with Section 2.1(a) hereof. Any excess payroll deductions not used

as a result of ESPP share limitations shall be distributed to each participant without interest. If a fractional number of Shares results, then such number shall be rounded down to the next whole number, and the excess payroll deductions shall be distributed to the applicable participant without interest.

     (b) Immediately after the consummation of the Offer, each outstanding award of Restricted Company Common Stock granted under the Company’s 1996 Stock Option Plan or the Kos Incentive Plan, or otherwise, not acquired by Parent or Merger Sub pursuant to the Offer shall vest in full and cease to be subject to restrictions and the holders of such awards of Restricted Company Common Stock outstanding immediately prior to the Effective Time shall be entitled to receive the Merger Consideration pursuant to Section 2.1(a).

(the “ PharmaBio Warrant ”) shall be entitled to receive upon exercise of the PharmaBio Warrant, if not already exercised prior to the Effective Time, during the period specified therein the amount in cash, without interest, equal to (i) the amount of cash that a holder of the Company Common Stock deliverable upon exercise of the PharmaBio Warrant would have been entitled to receive in the Merger if the PharmaBio Warrant had been exercised immediately before the Merger minus (ii) the exercise price of the PharmaBio Warrant, in accordance with the terms and conditions of the PharmaBio Warrant.

     SECTION 2.3 Surrender of Shares . (a) Prior to the Effective Time, Merger Sub shall enter into an agreement with a paying agent reasonably acceptable to the Company to act as its paying agent (the “ Paying Agent ”) for the payment of the Merger Consideration to which the shareholders of the Company shall become entitled pursuant to this Article II. At or prior to the Effective Time, Parent shall, or shall cause the Surviving Corporation to, deposit with the Paying Agent to be held in trust for the benefit of holders of Certificates all the cash necessary to pay for the Shares converted into the right to receive the Merger Consideration pursuant to Section 2.1(a) (such cash being hereinafter referred to as the “ Exchange Fund ”).

     (b) Promptly after the Effective Time, Parent shall cause to be mailed to each record holder, as of the Effective Time, of a Certificate which immediately prior to the Effective Time represented Shares, a form of letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Paying Agent) and instructions for use in effecting the surrender of the Certificates for payment of the Merger Consideration. Upon surrender to the Paying Agent of a Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive upon such surrender of such Certificate the Merger Consideration pursuant to Section 2.1(a) and such Certificate shall then be canceled. If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the Person requesting such payment shall have paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate surrendered

or shall have established to the satisfaction of the Surviving Corporation that such Tax either has been paid or is not applicable. Until surrendered as contemplated by this Section 2.3(b), each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender of such Certificate the Merger Consideration pursuant to Section 2.1(a). No interest shall be paid or accrue on the cash payable upon surrender of any Certificate.

     (c) At any time following the date that is twelve months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any portion of the Exchange Fund which have been made available to the Paying Agent and which have not been disbursed to holders of Certificates and thereafter such holders shall be entitled to look to Parent and the Surviving Corporation (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates. The Surviving Corporation shall pay all charges and expenses, including those of the Paying Agent, incurred by it in connection with the exchange of Shares for the Merger Consideration and other amounts contemplated by this Article II. None of Parent, Merger Sub, the Company or the Paying Agent shall be liable to any person in respect of any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. The Merger Consideration paid in accordance with the terms of this Article II in respect of Certificates that have been surrendered in accordance with the terms of this Agreement shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares of Company Common Stock represented thereby.

     (d) After the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares that were outstanding prior to the Effective Time. After the Effective Time, Certificates presented to the Surviving Corporation for transfer shall be canceled and exchanged for the consideration provided for, and in accordance with the procedures set forth in, this Article II.

     (e) In the event that any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed, and, if reasonably requested, the posting by the holder of a bond in customary amount as indemnity against any claim that may be made against it with respect to the Certificate, the Paying Agent will deliver in exchange for the lost, stolen or destroyed Certificate the Merger Consideration payable in respect of the Shares represented by such Certificate pursuant to this Article II.

     (f) The Paying Agent shall invest the cash included in the Exchange Fund, as directed by Parent, on a daily basis in (i) obligations of or guaranteed by the United States of America or any agency or instrumentality thereof, (ii) money market accounts, certificates of deposit, bank repurchase agreement or banker’s acceptances of, or demand deposits with, commercial banks having a combined capital and surplus of at least $5,000,000,000, or (iii) commercial paper obligations rated P-1 or A-1 or better by Standard &Poor’s Corporation or Moody’s Investor Services, Inc. Any profit or loss resulting from, or interest and other income produced by, such investments shall be for the account of Parent. If for any reason (including losses) the cash in the Exchange Fund shall be insufficient to fully satisfy all of the payment obligations to be made in cash by the Exchange Agent hereunder (but subject to Section 2.4),

Parent shall promptly deposit cash into the Exchange Fund in an amount which is equal to the deficiency in the amount of cash required to fully satisfy such cash payment obligations.

     SECTION 2.4 Withholding Taxes . Notwithstanding anything in this Agreement to the contrary, Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any former holder of Shares pursuant to this Agreement any amount as may be required to be deducted and withheld with respect to the making of such payment under applicable tax Laws. To the extent that amounts are so properly withheld by the Paying Agent, the Surviving Corporation or Parent, as the case may be, and are paid over to the appropriate Governmental Entity in accordance with applicable Law, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by the Paying Agent, the Surviving Corporation or Parent, as the case may be.
