(vi) Opinions, if any, to be rendered with respect to such products as ENGELBERG identifies in writing to SPINC within sixty (60) days following the execution of this Agreement, provided, however, that an Initial Written Opinion, as defined hereinafter, is rendered with respect to each such product no later than September 30, 1993; that such Initial written Opinions are limited to a total of no more than six (6) products belonging to a maximum of three (3) different recognized chemical classes of drugs; and that each such product is not subject to a non-patent exclusivity which prohibits an ANDA from being filed before December 31, 1994. (c) The services set forth in Paragraph 1.1(b) shall be performed personally by ENGELBERG or by individuals retained by ENGELBERG who are acting under ENGELBERG's personal direction and control. The retention of such individuals shall be subject to the approval of SPINC, which approval shall not be unreasonably withheld, it being recognized by SPINC that the compatibility between ENGELBERG and such individuals is critical to the successful completion of the purpose of this Agreement. ENGELBERG and SPINC agree that an Initial Written Opinion with respect to any potential patent challenge, i.e., a written opinion which includes, a recommendation to proceed with a patent challenge, the facts, documents and law justifying the challenge and the basic strategy to be used in defending against a subsequent claim of infringement * redacted pursuant to confidential treatment request. -4- by the patent owner, is critical to the success of any patent challenge. ENGELBERG agrees that he shall personally conduct the evaluation necessary to prepare that Initial Written Opinion and shall author the Initial Written Opinion. SPINC agrees that subsequent to the preparation of an Initial Written Opinion, ENGELBERG shall have complete discretion as to the delegation of responsibility for the defense of patent litigation and is not obligated to personally devote his full time to the performance of the services set forth in paragraph 1.1(b). SPINC acknowledges that it has already received an Initial Written Opinion with respect to buspirone hydrochloride, ********* ******** ******************** ********* ********** *** ********* ************** 1.2. Nothing in this Agreement shall prevent ENGELBERG from engaging in any business or activity including, without limitation, any pharmaceutical business or activity or any legal activity, including patent challenges involving drugs, except that ENGELBERG agrees that he will not directly or indirectly engage in any business or legal activity (i) with respect to any drug product if such involvement could diminish the exclusivity or market lead time of SPINC with respect to a product for which ENGELBERG has rendered an Initial Written opinion under paragraph 1.1 (a) or (b) or (ii) which would involve the use of confidential business information of SPINC acquired by ENGELBERG in the course of performing his duties under this Agreement. ENGELBERG further represents that as of the date of this Agreement he has not had any discussions with any third party or entered into any Agreement with any third party with respect to the possibility of engaging in drug patent challenges * redacted pursuant to confidential treatment request. -5- and that the list of products to be identified by ENGELBERG under paragraph 1.1 (b) (vi) of this Agreement shall include all of the products listed in the Orange Book which he then intends to study for possible patent challenges. 1.3 Nothing in this Agreement shall be construed as requiring ENGELBERG to engage in any counseling or consultation with SPINC except with respect to products which are the subject of ENGELBERG's obligations under paragraph 1.1 (a) or (b). 2. Duties and Obligations of SPINC ------------------------------- 2.1. SPINC agrees that it will perform the following activities during the life of this Agreement: (a) Promptly provide ENGELBERG with all assistance requested by ENGELBERG to obtain information regarding the availability of raw materials or other technical information, or to take such other actions, as needed, to determine the feasibility of producing a product for which an Initial Written Opinion has been or is proposed to be prepared by ENGELBERG. (b) As to each product identified in paragraph 1.1(b), or any other product, for which the parties hereto determine that it is appropriate to prepare and serve a Patent Certification Notice, carry out, at SPINC's sole expense, all of the work required to formulate a generic drug product and to obtain the stability, dissolution, bioequivalence and other data required to obtain approval of an ANDA under the 1984 Act. SPINC recognizes that it is essential to the objectives of this Agreement that all such -6- technical work be completed and submitted to the FDA in the initial ANDA application before any Patent Certification Notice can be filed. (c) Carry out, at SPINC's sole expense, all of the manufacturing and sales activities relating to each drug product for which an ANDA approval is obtained for a product containing a Patent Certification Notice prepared as a result of studies carried out pursuant to this Agreement. 3. Warranties and Representations ------------------------------ 3.1. It is understood by the parties hereto that nothing herein shall be construed as obligating either party hereto to proceed with any patent challenge or the development of any product unless and until all legal and technical issues relating to such product are completely evaluated and each party hereto has independently determined that a patent challenge is justified. However, in the event that either party decides, for any reason, not to proceed with a particular product the other party hereto shall be free to do so subject to such obligations to the other as are set forth in this Agreement. 3.2. Each of the parties agrees to use its best efforts to meet its obligations as defined in Paragraph 1 and 2 of this Agreement. 3.3. SPINC acknowledges that there is no warranty or other assurance by ENGELBERG that the studies to be conducted by ENGELBERG under paragraph 1.1(b)(vi) will result in any written opinions recommending patent challenges or that litigation with -7- respect to the patents on which Initial Written Opinions have already been rendered will result in a decision holding any patent invalid, unenforceable or non-infringed despite his best efforts. 3.4. ENGELBERG acknowledges that there is no assurance by SPINC that it can procure timely approval of an ANDA despite the use of its best efforts. 3.5. SPINC agrees that it will not make any oral or written statements concerning this Agreement at any time which are inconsistent with the terms of this Agreement. SPINC further agrees that it will not make any written statement about this Agreement in connection with any prospectus seeking public or private investment in SPINC or its affiliates without the prior approval of ENGELBERG, which approval will not be unreasonably withheld provided that any such statement calls clear attention to the acknowledgment set forth in paragraph 3.3 of this Agreement and further notes that ENGELBERG is free to terminate his obligations in accordance with paragraph 6.2 of this Agreement. 4. Reimbursement of Expenses ------------------------- 4.1. SPINC shall either directly pay or shall reimburse ENGELBERG for all out-of-pocket expenses incurred in the course of performing services under this Agreement.

For the purpose of this Agreement: -9- (a) In the case of buspirone, ********* *** ********** ********** products and the products referred to in paragraphs 5.7 and 5.8 of this Agreement, "Marginal Gross Profit" shall mean "Net Sales" less **** of the Cost of Goods.

No costs incurred in the manufacture, packaging and sale of the Product shall be deducted in determining "Net Sales". Sales to affiliated companies at prices which are less than those charged in an arm's length transaction with a third party shall be adjusted to reflect the amount which would have been received in an arm's length transaction, except that no adjustment shall be required in those instances where the lower selling price results from a successful competitive bid on a hospital or government contract and the selling price is determined in * redacted pursuant to confidential treatment request. -10- accordance with past mutual profit reduction practices between SPINC and its affiliate with respect to such contracts.

If, as to any product for which SPINC would be obligated to make payments to ENGELBERG pursuant to paragraph 5.1, SPINC negotiates an agreement with the patent owner -11- which results in a monetary payment to SPINC or in the payment of other consideration such as goods, trade discounts, etc., in exchange for an agreement by SPINC to refrain from the independent manufacture or sale of the patented product, ENGELBERG shall receive fifty (50%) percent of the value of such monetary payments or other consideration and such payments shall be made to ENGELBERG promptly after receipt of the payment or benefit by SPINC. 5.4 SPINC may deduct from the payments to be made to ENGELBERG any fees actually paid to additional counsel who are retained pursuant to either paragraph 1.1 (c) or 6.3 of this Agreement and such out-of pocket expenses of such additional counsel as are incurred due to the retention of additional counsel, e.g. travel, meals, additional copies, etc. Out-of-pocket expenses for transcripts, depositions, expert witnesses and any other type of expense which would have been incurred even though no additional counsel had been retained shall not be deductible from the payments to ENGELBERG.

Such records shall be open to inspection by ENGELBERG or his authorized representative during normal business hours on reasonable notice, but not more than twice during any calendar year. 5.7 The payments required under paragraph 5.1 shall be made by SPINC with respect to its manufacture and sale of ************* ********** products until November 25, 1992 except that: (a) The Cost of Goods shall include **** of the royalty paid to Sandoz.
