The closing of the Merger (the "Closing") shall take ------- ------- place on the first Business Day after the satisfaction or waiver (subject to applicable Law) of the conditions (excluding conditions that, by their nature, cannot be satisfied until the Closing Date) set forth in Article 7, unless this Agreement has been theretofore terminated pursuant to its terms or unless another time or date is agreed to in writing by the parties hereto (the actual date of the Closing being referred to herein as the "Closing Date"). The Closing ------------ shall be held at the offices of Latham & Watkins, 633 West Fifth Street, Suite 4000, Los Angeles, California 90071, unless another place is agreed to in writing by the parties hereto.

At the Effective Time, the effect -------------------- of the Merger shall be as provided in the applicable provisions of the WBCA. Without limiting the generality of the foregoing, at the Effective Time, except as otherwise provided herein, all the property, rights, privileges, powers and franchises of the Company and Merger Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Sub shall become the debts, liabilities and duties of the Surviving Corporation. Section 1.4 Articles of Incorporation; Bylaws. --------------------------------- (a) Articles of Incorporation. At the Effective Time, the Articles of Incorporation of the Surviving Corporation shall be amended in their entirety to read as the Articles of Incorporation of Merger Sub, until thereafter changed or amended as provided therein or by applicable Law, except that Article I thereof shall be amended to read as follows: "The name of the Corporation is Immunex Corporation." Such Articles shall not be inconsistent with Section 6.10. (b) Bylaws. At the Effective Time, the Bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation, until thereafter changed or amended as provided therein or by applicable Law. Such Bylaws shall not be inconsistent with Section 6.10. Section 1.5 Directors and Officers of the Surviving Corporation. The --------------------------------------------------- directors of Merger Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold office in accordance with the Articles of Incorporation and Bylaws of the Surviving Corporation.

ARTICLE 2. CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES Section 2.1 Conversion of Securities. At the Effective Time, by virtue ------------------------ of the Merger and without any action on the part of Merger Sub, the Company or the holders of any of the following securities: 2 (a) Conversion Generally. Each share of common stock, par value $0.01 per share, of the Company ("Company Common Stock") issued and outstanding -------------------- immediately prior to the Effective Time (other than any shares of Company Common Stock to be canceled pursuant to Section 2.1(b) and dissenting shares referred to in Section 2.1(e)) shall be converted, subject to Section 2.2(e), into the right to receive (i) 0.440 (the "Exchange Ratio") of a share of common stock, -------------- par value $0.0001 per share ("Parent Common Stock"), of Parent (the "Common ------------------- ------ Stock Consideration") and (ii) $4.50 in cash (the "Cash Consideration," and ------------------- ------------------ together with the Common Stock Consideration, the "Merger Consideration"). All -------------------- such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each certificate previously representing any such shares shall thereafter represent the right to receive the Merger Consideration payable in respect of such shares of Company Common Stock. (b) Parent-Owned Shares. All shares of Company Common Stock owned by Parent or any of its Subsidiaries shall be cancelled and retired and shall cease to exist and no Merger Consideration or other consideration shall be delivered in exchange therefor. (c) Merger Sub. Each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and be exchanged for one newly and validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation. (d) Change in Shares. If, between the date of this Agreement and the Effective Time, the outstanding shares of Parent Common Stock or Company Common Stock shall have been changed into, or exchanged for, a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares, the Exchange Ratio and the Option Exchange Ratio shall be correspondingly adjusted to provide the holders of Company Common Stock and Company Options the same economic effect as contemplated by this Agreement prior to such event. (e) Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, with respect to each share of Company Common Stock as to which the holder thereof shall have properly complied with the provisions of Chapter 23B.13 of the WBCA as to dissenters' rights (each, a "Dissenting Share"), if ---------------- any, such holder shall be entitled to payment, solely from the Surviving Corporation, of the appraisal value of the Dissenting Shares to the extent permitted by and in accordance with the provisions of Chapter 23B.13 of the WBCA; provided, however, that (i) if any holder of Dissenting Shares, under the circumstances permitted by and in accordance with the WBCA, affirmatively withdraws such holder's demand for appraisal of such Dissenting Shares, (ii) if any holder of Dissenting Shares fails to establish such holder's entitlement to dissenters' rights as provided in the WBCA or (iii) if any holder of Dissenting Shares takes or fails to take any action the consequence of which is that such holder is not entitled to payment for such holder's shares under the WBCA, such holder or holders (as the case may be) shall forfeit the right to appraisal of such shares of Company Common Stock and such shares of Company Common Stock shall thereupon be deemed to have been converted, as of the Effective Time, into and represent the right to receive the Merger Consideration payable in respect of such shares of Company Common Stock. The Company shall give Parent prompt notice of any demands received by the Company for appraisal of shares of Company Common 3 Stock, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not settle, make any payments with respect to, or offer to settle, any claim with respect to Dissenting Shares without the written consent of Parent. (f) Associated Rights. References in this Agreement to Parent Common Stock shall include, unless the context requires otherwise, the associated Preferred Share Purchase Rights issued pursuant to the Amended and Restated Rights Agreement dated as of December 12, 2000 between Parent and American Stock Transfer and Trust Company, as Rights Agent (the "Rights Plan"). ----------- Section 2.2 Exchange of Certificates. ------------------------ (a) Exchange Agent. As of the Effective Time, Parent shall deposit, or shall cause to be deposited, with American Stock Transfer and Trust Company or another bank or trust company designated by Parent and reasonably satisfactory to the Company (the "Exchange Agent"), for the benefit of the -------------- holders of shares of Company Common Stock, for exchange, in accordance with this Article 2, through the Exchange Agent, sufficient cash and certificates representing shares of Parent Common Stock to make all deliveries pursuant to this Article 2. Parent agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends and other distributions pursuant to Section 2.2(c). The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid for shares of Company Common Stock pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 2.2(c) and 2.2(e) hereof, the Exchange Fund shall not be used for any other purpose. Any cash and certificates representing Parent Common Stock deposited with the Exchange Agent (including the proceeds from sales of Excess Shares in accordance with Section 2.2(e)) shall be referred to as the "Exchange Fund." ------------- (b) Exchange Procedures. Promptly after the Effective Time, Parent shall instruct the Exchange Agent to mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the "Certificates") (i) ------------ a letter of transmittal (which 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 Exchange Agent and shall be in customary form) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificates. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, properly completed and duly executed, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate, cash in lieu of fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c), and the Certificate so surrendered shall forthwith be canceled. No interest shall be paid or accrued on any Cash Consideration, cash in lieu of fractional shares or on any unpaid dividends and distributions payable to holders of Certificates. In the event of a transfer of ownership of shares of Company Common Stock which is not registered in the transfer records of the Company, the Merger Consideration payable in respect of such shares of Company Common Stock may be paid to a 4 transferee if the Certificate representing such shares of Company Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate, cash in lieu of any fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.2(c). (c) Distributions with Respect to Unexchanged Shares of Parent Common Stock. No dividends or other distributions declared or made with respect to shares of Parent Common Stock, with a record date after the Effective Time, shall be paid to the holder of any unsurrendered Certificate, and no cash payment in lieu of fractional shares of Parent Common Stock shall be paid to any such holder pursuant to Section 2.2(e), unless and until the holder of such Certificate shall surrender such Certificate. Subject to the effect of escheat, Tax or other applicable Laws, following surrender of any such Certificate, there shall be paid to such holder of the certificates representing whole shares of Parent Common Stock issuable in exchange therefor, without interest, (i) promptly, the amount of any cash due pursuant to Section 2.1 and cash payable in lieu of fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date at or after the Effective Time theretofore paid with respect to such whole shares of Parent Common Stock and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date at or after the Effective Time but prior to such surrender and a payment date subsequent to such surrender, payable with respect to such whole shares of Parent Common Stock. (d) Further Rights in Company Common Stock. The Merger Consideration issued upon conversion of a share of Company Common Stock in accordance with the terms hereof (including any dividends or distributions pursuant to Section 2.2(c) or Section 2.2(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such share of Company Common Stock. (e) Fractional Shares. No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Parent Common Stock shall be payable on or with respect to any fractional share and such fractional share interests shall not entitle the owner thereof to any rights of a stockholder of Parent. (i) As promptly as practicable following the Effective Time, the Exchange Agent shall determine the closest number of whole shares of Parent Common Stock represented by the aggregate of the fractional share interests in Parent Common Stock to which all holders of Company Common Stock are entitled (the "Excess Shares"). As soon after the Effective Time as practicable, the ------------- Exchange Agent, as agent for such holders of Parent Common Stock, shall sell the Excess Shares at then prevailing prices on Nasdaq, all in the manner provided in this Section 2.2(e). 5 (ii) The sale of the Excess Shares by the Exchange Agent shall be executed on Nasdaq through one or more member firms of Nasdaq and shall be executed in round lots to the extent practicable. Until the net proceeds of any such sale or sales have been distributed to such holders of Company Common Stock, the Exchange Agent shall hold such proceeds in trust for such holders of Company Common Stock as part of the Exchange Fund. All commissions, transfer Taxes and other out-of-pocket transaction costs of the Exchange Agent incurred in connection with such sale or sales of Excess Shares shall be deducted from the Exchange Fund. In addition, the Exchange Agent's compensation and expenses in connection with such sale or sales shall be deducted from the Exchange Fund. The Exchange Agent shall determine the portion of such net proceeds to which each holder of Company Common Stock shall be entitled, if any, by multiplying the amount of the aggregate net proceeds by a fraction the numerator of which is the amount of the fractional share interest to which such holder of Company Common Stock is entitled (after taking into account all shares of Parent Common Stock to be issued to such holder) and the denominator of which is the aggregate amount of fractional share interests to which all holders of Company Common Stock are entitled. (iii) As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Company Common Stock with respect to any fractional share interests, the Exchange Agent shall promptly pay such amounts to such holders of Company Common Stock subject to and in accordance with the terms of this Article 2. (f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for one year after the Effective Time shall be delivered to Parent, upon demand, and, from and after such delivery to Parent, any holders of Company Common Stock who have not theretofore complied with this Article 2 shall thereafter look only to Parent for the Merger Consideration payable in respect of such shares of Company Common Stock, any cash in lieu of fractional shares of Parent Common Stock to which they are entitled pursuant to Section 2.2(e) and any dividends or other distributions with respect to Parent Common Stock to which they are entitled pursuant to Section 2.2(c), in each case, without any interest thereon. (g) No Liability. None of Parent, the Surviving Corporation or the Company shall be liable to any holder of shares of Company Common Stock for any such shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law. (h) Lost Certificates. If 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 required by Parent, the posting by such person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.2(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.2(c), in each case, without any interest thereon. 6 (i) Withholding. Parent or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as Parent or the Exchange Agent are required to deduct and withhold under the Code, or any Tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock in respect of whom such deduction and withholding was made by Parent or the Exchange Agent. (j) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent, on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent upon termination of the Exchange Fund pursuant to Section 2.2(f). In the event the cash in the Exchange Fund shall be insufficient to fully satisfy all of the payment obligations to be made by the Exchange Agent hereunder, 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 payment obligations. Section 2.3 Stock Transfer Books. At 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 of Company Common Stock theretofore outstanding on the records of the Company. From and after the Effective Time, the holders of certificates representing shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided herein or by Law. On or after the Effective Time, any Certificates presented to the Exchange Agent or Parent for any reason shall be converted into the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificates, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.2(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.2(c), without any interest thereon. Section 2.4 Stock Options. ------------- (a) At the Effective Time, each Company Option, other than Cancelled Company Options, then outstanding under any Company Stock Option Plan, whether or not then exercisable, shall be converted into an option to purchase Parent Common Stock in accordance with this Section 2.4(a). Each Company Option so converted shall continue to have, and be subject to, the same terms and conditions (including vesting schedule) as set forth in the applicable Company Stock Option Plan and any agreements thereunder immediately prior to the Effective Time, except that, as of the Effective Time, (i) each Company Option shall be exercisable (or shall become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product of the number of shares that were issuable upon exercise of such Company Option immediately prior to the Effective Time multiplied by 0.52 (the "Option Exchange --------------- Ratio"), rounded down to the nearest whole number of shares of Parent Common ----- Stock, (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such Company Option so converted shall be equal to the quotient determined by dividing the exercise price per share of Company Common Stock at which such Company Option was exercisable immediately prior to the Effective Time by the Option 7 Exchange Ratio, rounded up to the nearest whole cent, and (iii) each Company Option which (a) is outstanding as of the date of this Agreement, (b) remains outstanding at the Effective Time, and (c) constitutes an Accelerated Company Option immediately prior to the Effective Time, shall be fully vested and exercisable as to all shares of Parent Common Stock subject thereto. Notwithstanding the foregoing, the conversion of any Company Options which are "incentive stock options," within the meaning of Section 422 of the Code, into options to purchase Parent Common Stock shall be made so as not to constitute a "modification" of such Company Options within the meaning of Section 424 of the Code. (b) At the Effective Time, each Cancelled Company Option then outstanding under any Company Stock Option Plan shall be cancelled, and in exchange therefor, shall be converted into an option ("Replacement Option") to purchase ------------------ that number of whole shares of Parent Common Stock equal to the product of the number of shares subject to the related Cancelled Company Option multiplied by 0.4, rounded down to the nearest whole number of shares of Parent Common Stock, with an exercise price per share equal to the fair market value of a share of Parent Common Stock as of the date of grant of the Replacement Option (which shall be as of the close of market on the date of the Effective Time)and otherwise subject to the terms and conditions (including the vesting schedule) that were applicable to the related Cancelled Company Option immediately prior to the Effective Time, and neither the vesting nor exercisability of any Cancelled Company Option or Replacement Option shall be accelerated except as provided in the addendums to the Company Stock Option Plans. Section 2.5 Employee Stock Purchase Plan. At the Effective Time, each ---------------------------- outstanding purchase right under the Immunex Corporation 1999 Employee Stock Purchase Plan (the "ESPP") shall be assumed by Parent in such manner that Parent ---- is a corporation "issuing or assuming a stock option in a transaction to which Section 424(a) applies" within the meaning of the Code, and shall be converted into a right to purchase Parent Common Stock in accordance with this Section 2.5. Each purchase right so assumed and converted by Parent under this Agreement will continue to have, and be subject to, the same terms and conditions set forth in the ESPP and the documents governing the outstanding purchase rights under the ESPP, immediately prior to the Effective Time, except that the purchase price of shares of Parent Common Stock and the number of shares of Parent Common Stock to be issued upon the exercise of such purchase rights shall be adjusted in accordance with the Option Exchange Ratio. Section 2.6 Employment Agreement. Simultaneously with the execution of -------------------- this Agreement, Parent has entered into an employment agreement with Edward V. Fritzky, which agreement shall become effective upon the Closing. Section 2.7 AHP Agreements. Simultaneously with the execution of this -------------- Agreement, each of that certain Stockholders' Rights Agreement by and among Parent, AHP, MDP Holdings, Inc. and Lederle Parenterals, Inc., that certain Amended and Restated Promotion Agreement by and between Parent and AHP, and that certain Agreement Regarding Governance and Commercial Matters by and among Parent, AHP and American Cyanamid Company (collectively, the "AHP Agreements") -------------- has been executed, which agreements shall become effective upon the Closing (except that the Agreement Regarding Governance and Commercial Matters shall be effective as of the date hereof). 8 Section 2.8 Role of Seattle and Rhode Island Following the Merger.

(c) Subject to the proviso contained in Section 6.5(b)(ii) and the proviso contained in the following sentence of this Section 6.5(c), the Company and Parent shall give (or shall cause their respective Subsidiaries to give) any notices to third parties, and use, and cause their respective Subsidiaries to use, reasonable best efforts to obtain any non-governmental third party consents, (i) necessary, proper or advisable to consummate the transactions contemplated in this Agreement, (ii) required to be disclosed in the Company Disclosure Letter or the Parent Disclosure Letter, as applicable, or (iii) required to prevent a Company Material Adverse Effect from occurring prior to or after the Effective Time or a Parent Material Adverse Effect from occurring after the Effective Time.

Section 6.7 Public Announcements. Parent and the Company will consult -------------------- with each other before issuing, and provide each other the opportunity to review and make reasonable comment upon, any press release or making any public statement with respect to this Agreement and the transactions contemplated hereby and, except as may be required by applicable Law or any listing agreement with Nasdaq, will not issue any such press release or make any such public statement prior to such consultation; provided, however, that each of Parent and the Company may make any public statement in response to specific questions by the press, analysts, investors or those attending industry conferences or financial analyst conference calls, so long as any such statements are not inconsistent with previous press releases, public disclosures or public statements made jointly by Parent and the Company and do not reveal non-public information regarding the other party.

(b) With respect to each benefit plan of Parent ("Parent Benefit Plan") in ------------------- which New Parent Employees subsequently participate, for purposes of determining vesting and entitlement to benefits, including for severance benefits and vacation entitlement (but not for 41 accrual of pension benefits), service with the Company (or predecessor employers to the extent the Company provides past service credit) shall be treated as service with Parent; provided, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits or to the extent that such service was not recognized under the applicable Company Benefit Plan.

Each Parent Benefit Plan shall waive pre-existing condition limitations to the same extent waived under the applicable Company Benefit Plan. New Parent Employees shall be given credit for amounts paid under a corresponding benefit plan during the same period for purposes of applying deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of the Parent Benefit Plan for the plan year in which the Effective Time occurs.

The obligations of Parent and the Surviving Corporation under this Section 6.10 shall not be terminated or modified in such a manner as to adversely affect any indemnitee to whom this Section 6.10 applies without the express written consent of such affected indemnitee (it being expressly agreed that the indemnitees to whom this Section 6.10 applies shall be third party beneficiaries of this Section 6.10).
