Except in accordance with the terms of this Agreement, no Member shall Transfer all or any part of its Membership Interest, or any interest therein, unless the Member (a) obtains the prior written consent of the other Member ("Nontransferring Member"), which consent may be withheld in the sole and absolute discretion of the Nontransferring Member, and (b) provides satisfactory evidence to the Company that such Transfer shall not violate applicable securities laws. Unless such prior requirements are met, the proposed Transfer may not take place, and any attempted Transfer in derogation hereof shall be deemed null and void.

The failure by any Member to appoint an investment banking firm within the time allowed shall be deemed equivalent to appointing the other Member's investment banking firm as the jointly appointed investment banking firm. Within sixty (60) days after the appointment of the jointly appointed investment banking firm or the Neutral Investment Banker, as the case may be, the jointly appointed investment banking firm or the Three Investment Bankers, by a majority vote, shall render their appraisal of the fair market value of the Membership Interest being purchased, which appraisal shall be binding and conclusive.

The Liquidator shall have full power and authority to take full account of the Company's assets and liabilities and to wind up and liquidate the affairs of the Company in an orderly and business-like manner as is consistent with obtaining the fair value thereof upon dissolution. The Company shall engage in no further business thereafter other than as necessary to operate on an interim basis, collect its receivables, pay its liabilities and liquidate its assets. 14.4 DISTRIBUTIONS IN LIQUIDATION (a) Upon dissolution of the Company and the liquidation of the assets of the Company pursuant to this Article 14, the Liquidator shall wind up the affairs of the Company and liquidate the assets as promptly as is consistent with obtaining fair value therefor and cause the remaining assets of the Company, including proceeds of sales or other dispositions in liquidation of assets, to be applied in accordance with the following priorities: -39- (i) First, to payment of the debts and obligations of the Company to its creditors (other than a Member), including sales commissions and other expenses incident to any sale of the assets of the Company; (ii) Second, to the establishment of such reserves as the Liquidator may deem reasonably necessary for any unliquidated contingent or unforeseen liabilities or obligations of the Company; (iii) Third, to the payment in full of loans (including for this purpose, accrued interest thereon through the date of payment) to the Company by the Members, pro rata, according to the relative amount of such unpaid loans (including for this purpose, accrued interest thereon through the date of payment) and then to the payment in full of any other debts and obligations of the Company to its Members (e.g., under service agreements), pro rata, according to the relative amount of such debts and obligations; (iv) Fourth, to the Members having positive Capital Accounts pro rata in accordance with their relative positive Capital Accounts (as determined after taking into account all Capital Account adjustments for the Company's Fiscal Year during which such liquidation occurs), until all such positive Capital Accounts are reduced to zero; and (v) Fifth, among the Members in proportion to their respective Membership Interests. The reserves established pursuant to clause (ii) of this Section 14.4(a) shall be paid over by the Liquidator to a bank or other financial institution to be held in escrow for the purpose of paying unliquidated, contingent or unforeseen liabilities or obligations, and, at the expiration of such period as the Liquidator deems advisable, such reserves shall be distributed to the Members or their assigns in the priority set forth in clauses (iii) and (iv) of this Section 14.4(a). Distributions to the Members pursuant to this Section 14.4(a) shall be made within the time period prescribed by Regulations Section 1.704- 1(b)(2)(ii)(b). (b) In the event the Liquidator determines that an immediate sale of part or all of the Company assets would cause undue loss to the Members, the Liquidator, in order to avoid such loss, may either (i) defer liquidation of any assets of the Company for a reasonable time, except those assets necessary to satisfy Company debts and obligations, or (ii) distribute the assets in kind to the Members. If any assets of the Company are to be distributed in kind, such assets shall be valued and shall be deemed sold at their fair market value and any gain or loss deemed realized shall be allocated to the Capital Accounts of the Members for purposes of applying this Section 14.4 as if such gain or loss had actually been fully realized. Any assets that are to be so -40- distributed shall be distributed on the basis of the fair market value thereof and any Member entitled to an interest in such assets shall receive such interest therein as a tenant-in-common with all other Members so entitled. The fair market value of such assets shall be determined by an appraiser to be selected by the Liquidator or by agreement of all the Members. In the event of such distribution in kind, the distributee Member shall not thereafter sell or otherwise Transfer or dispose of any interest in any assets so distributed which it holds as a tenant-in-common without first offering such interest in writing to the other tenant-in-common upon the same terms and conditions and for the same price as such proposed sale or Transfer. The other tenant-in-common shall have thirty (30) days after the receipt of such offer within which to accept the same and shall have the right to acquire such interest. If the other tenant-in- common shall fail to accept such offer within such period of time, such distributee Member shall be free to sell the interest in such assets upon the terms and conditions described in the offer disclosed to the other tenants-in- common free of any further rights of first refusal. 14.5 DEFICIT CAPITAL ACCOUNTS Except as may otherwise be required by law, notwithstanding anything to the contrary contained in this Agreement, to the extent that any Member has a Deficit Capital Account balance upon dissolution of the Company, that balance shall not be an asset of the Company and that Member shall not be obligated to contribute any amount to the Company to bring the balance of that Member's Capital Account to zero. 14.6 TERMINATION OF COMPANY AND AGREEMENT Upon the completion of the distributions in liquidation of the Company as provided in this Article 14, (a) the Liquidator shall take all actions as may be appropriate to finally dissolve and liquidate the Company and (b) this Agreement shall terminate.

ELI LILLY AND COMPANY ICOS CORPORATION By: /s/ Sidney Taurel By: /s/ George B. Rathman ------------------- -------------------- Sidney Taurel George B. Rathman President and Chief Executive Officer Chairman of the Board, President and Chief Executive Officer EXHIBIT E SCHEDULE OF LILLY CONTRIBUTIONS A. SCHEDULE OF INITIAL CONTRIBUTION UNDER SECTION 3.1.1(a) [ * ] B. SCHEDULE OF CONTRIBUTIONS UNDER SECTION 3.1.3 [ * ] [Exhibit E is continued on following page] /*/ Confidential Treatment Requested [ * ]. /*/ Confidential Treatment Requested -2- SCHEDULE 9.1.6 PROCEEDINGS Barr Laboratories, Inc. (Barr) and Geneva Pharmaceuticals, Inc. (Geneva) have each submitted Abbreviated New Drug Applications (ANDAs) seeking FDA approval to market generic forms of Prozac before the expiration of LILLY's patents. The ANDAs assert that LILLY's U.S. patents covering Prozac are invalid and unenforceable. In April 1996, LILLY filed suit against Barr in federal court in Indianapolis seeking a ruling that Barr's challenge to LILLY's patents is without merit. In June 1997, LILLY filed a similar suit against Geneva in the same court. The patent validity aspects of the case are currently set for trial in January 1999. While LILLY believes that the claims of Barr and Geneva are without merit, there can be no assurance that LILLY will prevail. An unfavorable outcome of this litigation could have a material adverse effect on LILLY's consolidated financial position, liquidity, or results of operations.
