ARTICLE V EXERCISE OF DISCRETIONARY COMPOUNDS OPTION 5.1 Discretionary Compounds Option. (a) In connection with the exercise of the KB Assignment Right, the KBI-E Assignment Right or the Required Sale, KB shall have the right and option, in its discretion, upon the terms and conditions as hereinafter provided in this Section 5.1, to purchase all of KBI-E's rights to any and all of the Discretionary Compounds. At the time of delivery of a Notice of 13 <PAGE> 17 Exercise pursuant to either Section 3.1 or Section 4.1 hereof, or of a Trigger Event Notice pursuant to Section 4.2 hereof, as the case may be, KB shall notify TR and KBI-E (the "Discretionary Compounds Information Notice") whether or not it elects to obtain the Discretionary Compounds Information (as hereinafter defined). (b) In the event that the Discretionary Compounds Information Notice indicates that KB does elect to obtain the Discretionary Compounds Information, TR and KBI-E shall have sixty (60) days from their receipt of the Discretionary Compounds Information Notice to provide KB with all information regarding the Discretionary Compounds reasonably requested by KB and necessary to evaluate which, if any, of the Discretionary Compounds to which it intends to purchase KBI-E's rights. Such information shall include, without limitation, (i) the total quantities of Discretionary Compounds sold, the net sales thereof and the Manufacturer's Cost therefor during the three (3) most recent Fiscal Years ending prior to the date of the Discretionary Compounds Information Notice; (ii) sales forecasts for the Discretionary Compounds; (iii) summaries of the Technical Information (as defined in the Amended and Restated KBI License) regarding each Discretionary Compound; and (iv) the Full Costs incurred by KBI-E and its Affiliates in connection with any investigation or development work previously undertaken by KBI-E and its Affiliates with respect to such Compounds, (all of the information set forth in clauses (i), (ii) and (iii) above and any other information reasonably necessary for KB to make such determination being collectively referred to herein as the "Discretionary Compounds Information"). (c) KBI-E shall keep, and shall cause its Affiliates to keep, true, accurate and complete records of the development and marketing expenditures and commitments therefor in respect of each Discretionary Compound and each product containing a Discretionary Compound in sufficient detail to permit the verification of the Discretionary Compounds Information. Upon KB's request, KBI-E shall permit an independent certified public accountant selected and paid by KB (except one to whom KBI-E has some reasonable objection) to have reasonable access during ordinary business hours to such of KBI-E's and its Affiliates' records regarding the Discretionary Compounds as may be necessary in such accountant's judgment to confirm to its reasonable satisfaction the accuracy of any Discretionary Compounds Information delivered to KB pursuant to this Section 5.1. Such accountant shall keep its findings confidential and shall not disclose to KB (or any of its Affiliates) any information except that it shall report to KB (i) its findings and any other information relating to the accuracy of the Discretionary Compounds Information delivered under this Section 5.1 and (ii) any restrictions on access to KBI-E's and its Affiliates' data which the accountant deems to be a restriction of scope with respect to its engagement. (d) Within sixty (60) days after KB shall have received all of the Discretionary Compounds Information, KB shall identify in a notice delivered to TR and KBI-E which, if any, of the Discretionary Compounds to which KB elects to seek an appraisal as to the fair market value of the rights thereto (the "Discretionary Compounds Appraisal Notice"). (e) Upon delivery of the Discretionary Compounds Appraisal Notice, if such notice indicates that KB elects to seek an appraisal as to one or more Discretionary Compounds, 14 <PAGE> 18 KB and KBI-E shall, at the sole cost and expense of KB, engage an appraisal firm of national reputation which is skilled in preparing appraisals of the future value of pharmaceutical products to determine the "fair market value" of KBI-E's rights with respect to the Discretionary Compounds that KB shall have identified pursuant to Section 5.1(d) hereof for purposes of determining the Discretionary Compounds Price. If the parties are unable to agree on an appraiser, then the appraiser shall be selected by the American Arbitration Association. Within thirty (30) days after the appraiser shall have determined such fair market value and the Discretionary Compounds Price shall have been determined for each such Discretionary Compound, KB shall notify TR and KBI-E whether, in its sole discretion, it shall purchase all of KBI-E's rights to any or all of the Discretionary Compounds. (f) On the later of five (5) business days thereafter and the applicable Assignment Date, KB shall pay to KBI-E an amount equal to the sum of the Discretionary Compounds Prices for each of the Discretionary Compounds, the rights to which it shall have elected to purchase pursuant to Section 5.1(e) (the "Discretionary Compounds Payment"). The Discretionary Compounds Payment shall be payable to KBI-E by wire transfer in Dollars of immediately available funds to an account designated in writing by KBI-E. The date on which the Discretionary Compounds Payment shall be made shall be referred to hereinafter as the "Discretionary Compounds Purchase Date." 5.2 Assignment of Rights in Respect of Discretionary Compounds. On the Discretionary Compounds Purchase Date, all of KBI-E's rights under the Assigned Contracts with respect to the Discretionary Compounds that KB has purchased shall be assigned to KB and the INDs and NDAs (each as defined in the Amended and Restated KBI License) for each such Discretionary Compound registered in the name of KBI-E (or any of its Affiliates) shall, as promptly as practicable thereafter, be transferred, to the extent permitted by applicable law and regulations and requirements of the FDA, to KB. 5.3 Assumed Liabilities. In the event KB purchases from KBI-E all of KBI-E's rights to any of the Discretionary Compounds pursuant to the terms of this Agreement, KB shall assume and be responsible for only those obligations and liabilities of KBI-E with respect to such Discretionary Compounds arising from and after the Discretionary Compounds Purchase Date, under the Assigned Contracts. KB shall not assume any other obligations or liabilities of KBI-E of any nature whatsoever, whether arising before or after the Discretionary Compounds Purchase Date with respect to the Discretionary Compounds, or otherwise, whether past, current or future, whether accrued, contingent, known or unknown. 5.4 Inventory. On the Discretionary Compounds Purchase Date, KB shall purchase from KBI-E and its Affiliates all inventories of Discretionary Compounds as to which rights are purchased on such date (including raw materials, work in process and finished goods) at Manufacturer's Cost. Notwithstanding the terms of Section 3.4 of the Master Restructuring Agreement, KB or its designee shall be permitted to use such acquired finished goods which include or contain the words "TR," "KBI" or "KBI-E" for a period of one (1) year from the Discretionary Compounds Purchase Date. 15 <PAGE> 19 5.5 No Further Option.

Nugent Title: President 20 <PAGE> 24 Schedule I Calculation of Multiple Based Upon Combined Weighted Net Sales of Tiered Rate Products and Exercise Year / Trigger Event Year The Multiple for use in determining the Formula Price shall be determined as follows: I. For Years 2008 and 2012 (if a Trigger Event has occurred prior to January 1, 2008 or if no Trigger Event has occurred) (a) If Average Combined Weighted Net Sales of Tiered Rate Products is less than or equal to $1.5 billion multiplied by the Pre-2016 Inflation Index, the Multiple is 18. (b) If Average Combined Weighted Net Sales of Tiered Rate Products is greater than $1.5 billion multiplied by the Pre-2016 Inflation Index and less than $3.0 billion multiplied by the Pre- 2016 Inflation Index, the Multiple shall be calculated by using the relevant variables set forth in Section IV below and each of the formulas set forth as follows: (i) Formula I M2 - ((M2 - M1) x (ACWNSTRP - (S1 x Index))/((S2-S1) x Index)) (ii) Formula II ((V1 x Index) + ((V2-V1) x Index)/((S2 - S1) x Index)x(ACWNSTRP - (S1 x Index))) -------------------------------------------------------------------------------- Average Annual Contingent Amounts (iii) Multiple Formula FormulaI + FormulaII -------------------- Multiple = 2 (c) If Average Combined Weighted Net Sales of Tiered Rate Products is greater than or equal to $3.0 billion multiplied by the Pre-2016 Inflation Index, the Multiple is 13. II. For Years 2008 Through 2015 If A Trigger Event Has Occurred On or After January 1, 2008 (a) If Average Combined Weighted Net Sales of Tiered Rate Products is less than or equal to $1.5 billion multiplied by the Pre-2016 Inflation Index, the Multiple is 18. (b) If a Trigger Event occurs in the years 2008 through 2015, and Average Combined Weighted Net Sales of Tiered Rate Products is greater than $1.5 billion multiplied by the Pre-2016 Inflation Index and less than $3.0 billion multiplied by the Pre-2016 Inflation Index, the Multiple shall be calculated using the Formulas set forth below: <PAGE> 25 (i) Using Table I (in Section V), obtain the values for each of the variables "V1", "V2", "M1" and "M2" for the Fiscal Year in which the Trigger Event has occurred, e.g., if a Trigger Event occurs in July 2010, the TE year is 2010 ("TE Year"). (ii) Using Table I (in Section V), obtain the values for each of the variables "V1", "V2", "M1" and "M2" for the Fiscal Year immediately following the Trigger Event year, e.g., if a Trigger Event occurs in July 2010, the next year is 2011 ("Next Year"). (iii) Subtract the "Next Year" variables (from II(b)(ii)) from the "TE Year" variables (from II(b)(i)) to obtain the "Variable Differential". (iv) Obtain a value for each of "V1", "V2", "M1" and "M2" using this formula: TE Year variable - (Variable Differential x (# of Months/12)) (v) Input the values for "V1", "V2", "M1" and "M2" obtained in II(b)(iv) into the formulas described in Section I(b) above. (c) If Average Combined Weighted Net Sales of Tiered Rate Products is greater than or equal to $3.0 billion multiplied by the Pre-2016 Inflation Index, the Multiple is 13. III. For Years after 2015 (a) The Multiple shall be 13. IV. Variables (a) "ACWNSTRP" = Average Combined Weighted Net Sales of Tiered Rate Products. (b) "Index" = Pre-2016 Inflation Index determined pursuant to Section 3.8 of the Master Restructuring Agreement. (c) "# of Months" = Number of full months that have elapsed since January 1st, during the Fiscal Year in which the Trigger Event has occurred; but, never more than 12 (e.g., if Trigger Event occurs on July 10th, 2010, then the # of Months is seven). (d) "M1" = See Table I. (e) "M2" = See Table I. (f) "S1" = $1.5 billion. (g) "S2" = $3.0 billion. (h) "V1" = See Table I. (i) "V2" = See Table I. 2 <PAGE> 26 V.
