If the Factory Cost for a Calendar Year exceeds * ( * ) of the Net Average Selling Price (as defined below) of the Product for such Calendar Year, the portion of the Factory Cost above * ( * ) shall be prorated to the Parties in an amount equal to the proration of 12 19 royalty payments to Net Sales. On or before December 1 of each Calendar Year during the Term, the Parties shall mutually agree on a Net Average Selling Price forecast ("ASP Forecast") and Factory Cost estimate ("Factory Cost Estimate") for the following Calendar Year and, if applicable, adjust royalties based on the ASP Forecast and Factory Cost Estimate. The Parties shall reconcile actual royalties payable for each Calendar Year on or before April 1 of the following Calendar Year. As used in this Section, "Net Average Selling Price" shall mean Net Sales divided by Net Units and "Net Units" shall mean units of the Product actually sold, less returns in accordance with Section 1.17. The Annual Net Sales thresholds set forth in subsections (a) through (e) of this Section 4.1 shall be proportionately reduced: (i) in the Calendar Year in which the First Commercial Sale occurs, by multiplying such Annual Net Sales thresholds by a fraction, (A) the numerator of which shall be the number of days remaining in such Calendar Year as of the First Commercial Sale and (B) the denominator of which shall be 365; and (ii) in the Calendar Year in which the Term expires, by multiplying such Annual Net Sales thresholds by a fraction, (X) the numerator of which shall be the number of days in such Calendar Year prior to the expiration of the Term and (Y) the denominator of which shall be 365. 4.2 Lump Sum Royalty Payments. In addition to the royalty payments pursuant to Section 4.1 and research and development funding payments pursuant to Sections 3.1 and 3.2, Abbott shall make lump sum royalty payments to API if any or all of the following Net Sales thresholds are attained during the time periods referenced below: Payment Net Sales Applicable Time Period Amount Level ---------------------- - ------ ----- (a) * * * (b) * * * (c) * * * (d) * * * 13 20 Each lump sum royalty payment referenced above shall be payable only once during the Term within ten (10) business days after the end of the applicable time period and shall be payable only if the applicable Net Sales level is attained during the applicable time period. 4.3 Royalty Reports and Payments. Commencing with the first Calendar Quarter in which Abbott, its Affiliates or Unaffiliated Sublicensees make the First Commercial Sale of the Product in the Territory, Abbott shall provide API with a written report of Net Sales on a country-by-country basis within forty-five (45) days after the last day of March, June, September and December for royalties accruing on Net Sales in the United States during the three (3) preceding calendar months and within seventy-five (75) days after the last day of February, May, August and November for royalties accruing on Net Sales in the Territory outside of the United States during the three (3) preceding calendar months. Concurrently with the submission of each such written report, Abbott shall pay or cause to be paid to API the total amount of royalties shown to be due thereon. 4.4 Currency. Abbott shall make all royalty payments to API pursuant to Section 4.2 in U.S. Dollars. Royalty payments earned shall be first determined by Abbott in the currency of the country where the Net Sales were made and then converted by Abbott directly to its equivalent in U.S. Dollars. The rates of exchange for converting the currencies involved to U.S. Dollars as quoted by the Wall Street Journal, Midwest Edition, as Foreign Exchange Rates quoted in New York as market rate (bid) on the last business day of the quarterly period in which the royalty payments were earned shall be used by Abbott to determine such conversion rates. 4.5 No Royalties Payable Between Affiliates. No royalties shall be payable to API on sales between Abbott, its Affiliates or Unaffiliated Sublicensees, or between Abbott Affiliates and Unaffiliated Sublicensees. 14 21 4.6 No Multiple Royalties. No multiple royalties shall be payable because the Product, its manufacture, use or sale is or shall be covered by multiple API Patents. 5.

Such accountant shall be required to execute a confidentiality agreement in a form reasonably acceptable to the audited Party and shall report to the auditing Party only the amount of any underpayment or overcharge. Within ten (10) business days after completion of such review, the Parties shall reconcile any underpayment or overcharge. The auditing Party shall pay the cost of any review of records conducted at its request under this Section. However, if the review establishes underpayment or overcharge by 15 22 the audited Party of over five percent (5%) during the period of the review, the audited Party shall promptly reimburse the auditing Party for the fees and expenses of the accountant. Such audit rights may be exercised by the Parties only with respect to records for the current calendar year and the preceding two (2) calendar years. 6.

Direct material is identified by specific lot numbers. Items normally included are; Raw drug. Diluting material such as the alcohol. Vial. Vial stopper. Vial seal Inline solution filters and compounding filters. Vial label Single unit carton. Shipper Any other specialized packaging material. Direct labor cost. Includes the cost of employees directly involved in the manufacture of the Product. Our direct labor employees are classified as Assistants, Operators, Attendants, Technicians, Senior Production Operators, Productions Equipment Specialists, and Group Leaders. The rate per hour includes the average base rate for all direct employees plus a fringe rate that includes vacations, holidays, insurance costs, pension, 401K, bonuses and legally mandated employer taxes. Standard product cost uses an Industrial Engineering estimate of the hours to perform each step of the production process. Additional procedures or employees required to handle explosive material would be added as a direct labor operation. Direct labor operations are normally considered to be: Drug dispensing. Drug mixing. Preparation of the filling equipment. Preparation of components such as washing vial stoppers. Preparation of printed materials, primarily labels. Filling of the vial. Post filling light inspection. Lyophilization Labeling. Packing. Variable overhead cost. Includes the costs of operating the plant which change as the volume of production in the plant changes. The major components of variable overhead are related to the production operator and include their overtime, time spent for training and plant meetings, and their uniforms and gowns. Any specialized employee safety equipment such as used in an explosion proof environment would be included in this category. Cost included in this category are assigned to standard product cost as a rate per hour applied to direct labor hours identified above. 52 Fixed overhead costs. Includes the other costs associated with operating a manufacturing plant. The key components are the cost of the quality assurance organization, material planning, purchasing, receiving, and warehousing, plant maintenance, utilities and engineering, the health and safety group, production supervision, and fixed costs such as depreciation taxes, and insurance. Investment in explosive proof equipment and changes to the facility required to handle explosive material would be included in this category. These costs are assigned to standard product cost based on fully utilized plant capacity. The standard product cost development process occurs once per year in the mid-summer time period. At that time, assumptions are made regarding inflation rates for raw material and wages, productivity improvements, and plant utilization levels. 53 EXHIBIT C U.S. PRODUCT DEVELOPMENT PLAN API shall conduct all clinical studies required to obtain Regulatory Approval in the United States, including but not limited to the studies referenced below, with the objective of obtaining U.S. NDA approval for the Product in injectable dosage form with an Empiric Claim on or before * .

(e) Neither affidavits nor settlement negotiations shall be admissible under any circumstances. As to all other matters, the neutral shall have sole discretion regarding the admissibility of any evidence. 6. Within seven (7) days following completion of the hearing, each party may submit to the other party and the neutral a post-hearing brief in support of its proposed rulings and remedies, provided that such brief shall not contain or discuss any new evidence and shall not exceed ten (10) pages. This page limitation shall apply regardless of the number of issues raised in the ADR proceeding. 7. The neutral shall rule on each disputed issue within fourteen (14) days following completion of the hearing. Such ruling shall adopt in its entirety the proposed ruling and remedy of one of the parties on each disputed issue but may adopt one party's proposed rulings and remedies on some issues and the other party's proposed rulings and remedies on other issues. The neutral shall not issue any written opinion or otherwise explain the basis of the ruling. 8. The neutral shall be paid a reasonable fee plus expenses. These fees and expenses, along with the reasonable legal fees and expenses of the prevailing party (including all expert witness fees and expenses), the fees and expenses of a court reporter, and any expenses for a hearing room, shall be paid as follows: (a) If the neutral rules in favor of one party on all disputed issues in the ADR, the losing party shall pay 100% of such fees and expenses. (b) If the neutral rules in favor of one party on some issues and the other party on other issues, the neutral shall issue with the rulings a written determination as to how such fees and expenses shall be allocated between the parties. The neutral shall allocate fees and expenses in a way that bears a reasonable relationship to the outcome of the ADR, with the party prevailing on more issues, or on issues of greater value or gravity, recovering a relatively larger share of its legal fees and expenses. 9. The rulings of the neutral and the allocation of fees and expenses shall be binding, non-reviewable, and non-appealable, and may be entered as a final judgment in any court having jurisdiction. 10. Except as provided in paragraph 9 of this Exhibit D or as required by law, the existence of the dispute, any settlement negotiations, the ADR hearing, any submissions (including exhibits, testimony, proposed rulings, and briefs), and the rulings shall be deemed Confidential Information. The neutral shall have the authority to impose sanctions for unauthorized disclosure of Confidential Information. 3 58 EXHIBIT E API TRADEMARK APPLICATIONS AND REGISTRATIONS API Trademarks Registered Case Number Mark Registration No. Next Renewal Date - ----------- ---- ---------------- ----------------- ARG-106 United States LF 1,785,153 08/03/03 ARG-701 United States Nyotran 2,173,459 07/14/08 59 EXHIBIT F FORM OF TRADEMARK ASSIGNMENT ASSIGNMENT WHEREAS, Aronex Pharmaceuticals, Inc., a corporation existing under the laws of the State of Delaware, having its principal place of business at 8707 Technology Forest Place, The Woodlands, Texas 77381-1191 is the owner of the United States Trademark Registrations as depicted on Schedule 1 attached hereto; and WHEREAS, Abbott Laboratories, a corporation existing under the laws of the State of Illinois, having its principal place of business at Abbott Park, Illinois 60064 is desirous of acquiring all right, title and interest in and to said Trademark Registrations, and WHEREAS, Aronex Pharmaceuticals, Inc. is willing to assign any and all of its right to the said Trademark Registrations, NOW, THEREFORE, for good and valuable consideration, receipt of which is hereby acknowledged, Aronex Pharmaceuticals, Inc. does hereby sell, transfer, convey and assign to Abbott Laboratories any and all of its right, title and interest in and to the trademarks and the Trademark Registrations associated therewith, including the goodwill of the business symbolized by the trademark.
