Exhibit 99.(A) OPTION AND WHOLESALE PURCHASE AGREEMENT THIS OPTION AND WHOLESALE PURCHASE AGREEMENT (the "Agreement") is entered into as of November 25, 1997 (the "Effective Date") at Indianapolis, Indiana, between ELI LILLY AND COMPANY ("Lilly") and LIGAND PHARMACEUTICALS INCORPORATED ("Ligand"). Whereas, Lilly has entered into certain agreements and amendments thereto with Seragen, Inc. ("Seragen") described in Section 5.13(g) below, copies of which agreements and amendments have been provided by Lilly to Ligand (the "Seragen Agreements"); and Whereas, Lilly and Seragen are currently developing DAB389IL-2, known as Ontak/TM/, pursuant to the Seragen Agreements, and Lilly has certain marketing, sales, promotion, distribution and other rights with respect thereto and certain manufacturing obligations as provided therein; and Whereas, Lilly desires to grant to Ligand an option pursuant to which, if and when Ontak/TM/ receives appropriate governmental approvals for marketing for the treatment of cancer indications in humans, Lilly will, subject to the terms and conditions of this Agreement and the Seragen Agreements, utilize Ligand as Lilly's exclusive (even as to Lilly) wholesaler of Lilly products consisting of, or containing as the active ingredient, Denileukin Diftitox (DAB389IL-2) (the "Products"), to be sold under the Ontak/TM/ name for the treatment of cancer indications in the territory defined below; and Whereas, the parties intend that, at all times, the rights and obligations described herein be consistent with and subject to the rights of Seragen under the Seragen Agreements; Now, therefore, in consideration of the foregoing, the mutual covenants set forth below and other consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 1. LIGAND OPTION TO BECOME EXCLUSIVE WHOLESALER. 1.1 LIGAND OPTION. For a period equal to the earlier of (a) ninety (90) days after the Effective Date of this Agreement, (b) until February 27, 1998, or (c) until the date which is three (3) business days after the date on which Ligand delivers to Lilly the notice referred to in Section 1.4, (the "Ligand Option Period"), Ligand shall have the option (the "Ligand Option") to become Lilly's exclusive wholesaler of the Products subject to the terms and conditions contained in this Agreement. 1.2 MANNER OF EXERCISE. To exercise the Ligand Option, Ligand shall deliver written notice of exercise to Lilly prior to the end of the Ligand Option Period in the manner set forth in Section 5.9 of this Agreement. 1.3 EFFECT OF LAPSE OF LIGAND OPTION. In the event Ligand does not exercise the Ligand Option prior to the end of the Ligand Option Period, or, in the event Ligand delivers written notice to Lilly prior to the end of the Ligand Option Period informing Lilly of its decision not to exercise the Ligand Option (the "Rejection Notice"), this Agreement shall automatically terminate and the parties only surviving rights and obligations under this Agreement shall be as follows: 1 (a) Subject to the terms and conditions set forth in the stock purchase agreement described in Section 4.6, Lilly shall purchase from Ligand, and Ligand shall sell and issue to Lilly, for Twenty Million Dollars ($20,000,000), the number of shares of Ligand's voting common stock (the "Shares") equal to Twenty Million Dollars ($20,000,000) divided by one hundred twenty percent (120%) of the average daily closing price for the Shares as reported by the National Association of Securities Dealers, Inc. on the twenty (20) consecutive trading days immediately preceding the date which is five (5) days prior to the earlier of (A) the date of the Rejection Notice or (B) the last day of the Ligand Option Period; and (b) Ligand shall have the right to designate either Targretin (as defined in that certain Development and License Agreement (Targretin) dated the date of this Agreement), Compound 268 or Compound 324 (each as defined in that certain Collaboration Agreement dated the date of this Agreement) for increased royalties, which right shall be exercised in the manner set forth and on the terms and conditions provided in Section 5.1(b) of the Targretin Agreement with respect to Targretin, or Section 6.1(b) of the Collaboration Agreement with respect to Compound 268 or Compound 324. 1.4 *** 2. CERTAIN COVENANTS OF LIGAND. 2.1 PROMOTION AND INVENTORIES. (a) Ligand agrees to promote, sell and book sales of, the Products in the Territory (as defined below) as the exclusive (even as to Lilly) wholesaler of the Products for Lilly Indications (as defined in the Seragen Agreements) in the Territory; and to purchase from Lilly Ligand's entire requirements for the Products. Ligand acknowledges that pursuant to the Seragen Agreements, Seragen has retained the right to market the Products for certain indications and in certain geographic territories, and that Ligand's rights hereunder shall relate only to those Products, those indications and those territories to which Lilly has rights under the Seragen Agreements. The United States, Canada, and, upon Ligand's appointment as exclusive wholesaler of the Products in the European Union, as provided for in Section 3, the European Union and the European Union Countries (as defined in the Seragen Agreements) are referred to collectively in this Agreement as the "Territory." (b) To the extent that Ligand shall, with the prior approval of both Ligand and Lilly given or withheld in their respective sole discretion, undertake the physical distribution of the Products, Ligand agrees to provide full distribution efforts for the Products; to maintain the Products under proper conditions, both in storage and in transit to its customers, *** ; and to supply only Products that are not out-of-date, damaged, or shopworn; provided, however, unless and until the parties agree otherwise, Lilly shall provide the distribution services specified in Section 3.1(c). If Ligand does undertake physical distribution, Ligand shall provide to Lilly quarterly upon Lilly's 2 request a listing of Ligand's complete and current inventory of Products by item and package size certified to be accurate by Ligand. 2.2 SALES EFFORT. Ligand agrees to use commercially reasonable selling efforts to, and otherwise promote, the Products, and not to: (a) Refuse or fail to supply promptly the Products when specified; (b) Fail to include in its system for determining its prices to its customers any provisions necessary to comply with the other provisions of this Agreement or enter into any agreement which would preclude Ligand from offering for sale a Product at any price acceptable to Ligand; or (c) Sell any Products to any party Ligand has reason to believe plans to use the Products or sell the Products for use outside the Territory. Ligand agrees that it shall hire and maintain a sales force appropriate for marketing of the Products in the Territory, develop and implement appropriate marketing plans, develop and utilize sales literature and other promotional aids, hold symposia for key physicians, and otherwise perform the duties associated with a promoter of the Products in the Territory. 2.3 SALES REPORTS. (a) Ligand shall have the right, but not the obligation, to report information regarding its sales of Products to one or more third parties organized to collect and report sales data to its subscribers. (b) During the term of this Agreement and after first commercial sale of a Product, in the Territory, Ligand shall furnish or cause to be furnished to Lilly on a quarterly basis a written report or reports covering each calendar quarter (each such calendar quarter being sometimes referred to herein as a "reporting period") showing (i) the Net Sales (as defined in Schedule 3.1(a) to this Agreement) of the Product in each country during the reporting period by Ligand, its affiliates, sublicensees and assigns, and (ii) the royalties which shall have accrued under this Agreement in respect of such sales and the basis for calculating those royalties. With respect to sales of the Products invoiced in United States Dollars ("Dollars"), the Net Sales amounts and the amounts due to Lilly hereunder shall be expressed in Dollars calculated by using Ligand's then- current standard procedures and methodology. With respect to sales of the Products invoiced in a currency other than Dollars, the Net Sales shall be calculated using Ligand's then current standard exchange rate methodology for the translation of foreign currency sales into Dollars. Each quarterly report shall be accompanied by a listing of the exchange rates used in calculating Net Sales for such quarterly report. Ligand will at Lilly's reasonable request but not more frequently than once a calendar quarter inform Lilly as to the specific exchange rate translation methodology, if any, used for a particular country or countries. In 3 the event that any exchange rate translation methodology changes, Ligand will inform Lilly of the change in the quarterly report next due. Each quarterly report shall be due on the seventy-fifth (75th) day following the close of each reporting period. Ligand shall keep accurate records in sufficient detail to enable the amounts due hereunder to be determined and to be verified by the independent public accountants described hereunder. Ligand shall furnish annually to Lilly appropriate evidence of payment of any tax or other amount required by applicable laws or regulations to be deducted from any royalty payment, including any tax or withholding levied by a foreign taxing authority in respect of the payment or accrual of any royalty. (c) All payments shall be made in Dollars at the time of quarterly reporting. If at any time legal restrictions prevent the prompt remittance of any payments with respect to any country where the Products are sold, Ligand, its affiliates, assigns and sublicensees or marketing partners shall have the right and option to make such payments by depositing the amount thereof in local currency to Lilly's account in a bank or depository in such country. (d) Upon the written request of Lilly, at Lilly's expense and not more than once in or in respect of any calendar year, independent public accountants designated by Lilly and reasonably acceptable to Ligand shall verify the accuracy of the sales reports furnished by Ligand in respect of any calendar year ending not more than thirty-six (36) months prior to the date of such notice. Upon the expiration of thirty-six (36) months following the end of any calendar year, the calculation of amounts payable with respect to such fiscal year shall be binding and conclusive upon Lilly, and Ligand, its Affiliates, and its sublicensees and marketing partners shall be released from any liability or accountability with respect to payments for such year. The report prepared by the independent public accountant, a copy of which shall be sent or otherwise provided to Ligand by such independent public accountant at the same time it is sent or otherwise provided to Lilly, shall contain the conclusions of such independent public accountant regarding the audit and will specify that the amounts paid to Lilly pursuant thereto were correct or, if incorrect, the amount of any underpayment or overpayment. If such independent public accountant's report shows any underpayment, Ligand shall remit or shall cause its sublicensees or marketing partners to remit to Ligand within thirty (30) days after Ligand's receipt of such report, (i) the amount of such underpayment and (ii) if such underpayment exceeds *** of the total amount owed for the calendar year then being audited, the reasonable and necessary fees and expenses of such independent public accountant performing the audit, subject to reasonable substantiation thereof. Any overpayments shall be fully creditable against amounts payable in subsequent payment periods. Lilly agrees that all information delivered or subject to review under this Section 2.3 or under any sublicensee or marketing agreement is Confidential Information (as defined in Section 5.14) and that Lilly shall retain all such information in confidence. 2.4 PAYMENT FOR PRODUCTS. Ligand agrees to pay in full within thirty (30) days *** each invoice delivered by Lilly to Ligand for the Products sold under this Agreement in accordance with the applicable provisions of this Agreement; and to pay interest on all overdue amounts owing from Ligand to Lilly hereunder outstanding for more than 30 days ("overdue") at the Prime Rate as published in The Wall Street Journal in effect from time to time plus *** per 4 annum (or the highest amount allowed by law, if such lawful amount is lower than the foregoing) from the date the amounts become overdue. Ligand shall bear all credit risk in the Territory relating to collections from customers and third parties. 2.5 CONTROLLED SUBSTANCE DETERMINATION. In the event that any of the Products are determined to be controlled substances or subject to any regulatory requirements not provided for in this Agreement, the parties will agree on reporting and other responsibilities sufficient to allow each of them to fulfill their respective regulatory and other obligations relating thereto. 2.6 COMPLIANCE WITH APPLICABLE LAWS. Ligand agrees: (a) To comply fully with all foreign, federal, state, and local laws, regulations and rules applicable to its activities hereunder. (b) To provide prompt notice to Lilly of any civil, criminal, or administrative inquiry, inspection, investigation, or other action by any foreign, federal, state, or local authority arising under or concerning any laws, regulations or rules referred to in Section 2.6(a) or any other governmental inquiry, inspection, investigation or action known to Ligand and arising under or concerning any other laws, regulations or rules otherwise applicable in any way to the Products or any acts or omissions of Ligand or Ligand's employees or other agents or affiliates relating to the Products; to provide Lilly with full and complete information regarding the status, prosecution, proceeding and disposition of any such action; and, to the extent Lilly may become a party to or otherwise involved in any such matter, to fully cooperate with and assist Lilly in the prompt and lawful resolution of any such matter.

(d) Not to market, sell or otherwise promote the Products in violation of any of the requirements of the appropriate governmental or regulatory authorities of the applicable jurisdiction(s) in the Territory; not to make any false or misleading representations to customers or others regarding Ligand, Lilly or the Products or any representations, warranties or guarantees with respect to specifications, features or capabilities of the Products except as contained in package labeling, package inserts, promotional material or other communication media approved by Lilly; and not to promote or advertise the Products in any manner or with any labeling, inserts, packaging or ingredients not approved in advance by Lilly. (e) Not to engage directly or indirectly in any transaction, activity, or other act or omission that would violate the Foreign Corrupt Practices Act, Anti-Referral Payments Law, any laws administered by the FDA, or other similar laws of any other jurisdiction in the Territory. 5 2.7 TAX EXEMPTION CERTIFICATES. Ligand agrees to provide to Lilly a copy of Ligand's sales tax exemption certificate, whether it be a resale certificate, blanket exemption, or direct payment exemption under applicable laws, and to notify Lilly promptly of any change which affects Ligand's exemption status and to provide such other information or certifications as Lilly may reasonably request in order to minimize tax liability and to comply with applicable tax or other regulations of each of the jurisdictions included in the Territory in which Ligand sells Products. 2.8 CONTROLS. Ligand agrees to establish such internal controls and maintain such records as will assure compliance with its obligations under this Agreement and the ability of Lilly to conduct a meaningful review of such records. 2.9 EVIDENCE OF FINANCIAL CONDITION.

Upon failure to pay any amount when due, cancellation or termination of this Agreement, or with evidence of a condition of insolvency of Ligand or a Ligand subsidiary, affiliate or location materially affecting Ligand's obligations under this Agreement, Lilly reserves the right to offset any amount due and owing Lilly against amounts otherwise owing under this Agreement to Ligand or Ligand's subsidiaries, affiliates or locations. 2.11 FORECASTS. Ligand agrees to provide sales forecasts at such times and in such detail as Lilly may reasonably request in order to determine manufacturing requirements, including such information as Lilly may be required to provide pursuant to the Seragen Agreements.

Within thirty (30) days after the date that the Products are first sold at any time during the Term in the United States for use in cancer indications (the "Product Pricing Date") at an average net selling price or equivalent over a three-month period (the "Cycle Price") *** as reported to Lilly in a manner consistent with the reporting of Net Sales information pursuant to Section 2.3 (but excluding any prices which are clinical study, introductory, or special discount prices), Ligand shall issue shares (the "Pricing Shares") of its voting common stock to Lilly on 8 the following terms and conditions determined with reference to the Cycle Price and the average trading price of Ligand's voting common stock over the twenty (20) consecutive trading days immediately preceding the date which is five (5) consecutive days prior to the Product Pricing Date (the "Average Stock Price"). If the Cycle Price never *** or more during the Term, Lilly shall not be entitled to any Pricing Shares.

Thereupon, all rights to the Products, including without limitation Ontak/TM/, shall revert to Lilly; the parties shall have no further rights hereunder; and Ligand shall have no further obligation to issue additional shares under Sections 3.1 and 3.2. 4.4 LOW CYCLE PRICE TERMINATION RIGHT. If the average price of the Product sold in the United States *** for use in cancer indications determined over the first six months following the Product Pricing Date (the "Low Price Termination Period") (excluding in calculating such average price special introduction, or other promotional pricing not indicative of normal pricing practices) *** Ligand may elect within thirty (30) days after the last day of the Low Price Termination Period to relinquish all of its rights under this Agreement by delivering notice of termination of this Agreement to Lilly, and Lilly shall within thirty (30) days after receipt of such notice purchase $5 million of the voting common stock of Ligand at the average trading price for the twenty (20) consecutive trading days immediately preceding the date which is five (5) consecutive days prior to the date of delivery of such notice. 4.5 CERTAIN ADDITIONAL TERMINATION RIGHTS. *** Upon termination of this Agreement under this Section 4.5: 9
