The transition services to be provided by Chiron which Enzon may request and fees therefor are set forth on Exhibit 8.3B

which is attached hereto and made a part hereof. Skye shall submit invoices to Enzon for the payment of such requested and approved transitional services promptly after receipt of same from Chiron. Payments shall be made by Enzon to Skye within thirty (30) days of the invoice date. In addition, if during the period commencing as of the Effective Date and ending on May 15, 2003, Enzon is charged any discounts, chargebacks, rebates or returns with respect to sales of the Product, Skye shall reimburse Enzon for such amounts as set forth in Section 8.1.1.2.

8.4 Mode of Payment. Enzon shall make all payments required under this Agreement as directed by Skye from time to time in U.S. Dollars. For the purposes of computing Net Sales of Product sold in a currency other than U.S. Dollars, such currency shall be converted into U.S. Dollars at an exchange rate equal to the buy rate of U.S. dollars published in the East Coast Edition of The Wall Street Journal for the last business day of the applicable Calendar Quarter. Such payments shall be without deduction of exchange, collection or other charges.

8.5 Late Charges. Amounts not paid when due as set forth in this Section 8 shall be subject to a late charge at a rate of interest equal to the base lending rate on corporate loans posted by at least [**] percent ([**]%) of the U.S.’s largest banks, as reported on the date such payment is due by the East Coast Edition of The Wall Street Journal as the prime rate, plus [**] percent ([**]%), with daily compounding of interest. Payment by Enzon of such late charges shall not foreclose any other rights or remedies which Skye may have hereunder with respect to such late payments.

8.6 Records Retention. Enzon shall keep true, accurate and complete records with respect to the calculation of the Net Unit Selling Price, Net Sales and Supply Price paid under this Agreement for a period of three (3) years after the year in which the sale of the Product generating the same occurred, and in sufficient detail to allow Skye to confirm the accuracy of all payments made hereunder.

8.7 Audit Rights. At the request of Skye, Enzon, its Affiliates and sub-distributors, if any, shall permit an independent certified public accountant appointed by Skye, at reasonable times and upon reasonable notice (but in no event more than once per calendar year), to examine those records and all other material documents relating to or relevant to the Net Unit Selling Price, Net Sales and Supply Price in the possession or control of Enzon, its Affiliates, and/or sub-distributors, if any, for a period of two (2) years after same have accrued, as may be necessary: (i) to determine the correctness of any report or payment made under this Agreement; or (ii) to obtain information as to same with respect to any Calendar Quarter in the event of Enzon’s failure to report or pay pursuant to this Agreement. Said accountant shall not disclose to Skye any information other than information relating to said reports and payments. The results of any such examination shall be made available to both Parties. Skye shall bear the full cost of the performance of any such audit except as hereinafter set forth. If, as a result of any inspection of the books and records of Enzon, its Affiliates and/or sub-distributors, if any, it is shown that Enzon’s payments under this Agreement were less than the amount which should have been paid, then Enzon shall make all payments required to be made to eliminate any discrepancy revealed by said inspection within forty-five (45) days after Skye’s demand therefor. Furthermore, if the payments made by Enzon were less than [**] percent ([**]%) of the amount of payments that should have been paid with respect to the period in question, Enzon shall also reimburse Skye for the cost of such examination.

8.8 Taxes. In the event that Enzon is required to withhold any tax to the tax or revenue authorities in the Territory regarding any payment to Skye, such amount shall be deducted from the payment to be made by Enzon, and Enzon shall promptly notify Skye of such withholding and, within a reasonable amount of time after making such deduction, furnish Skye with copies of any tax certificate or other documentation evidencing such withholding. Each

Any such termination shall become effective at the end of such sixty (60)-day period unless the Breaching Party has cured any such breach or default prior to the expiration of such sixty (60)-day period (or, if such default cannot be cured within such sixty (60)-day period, if the Breaching Party has commenced and diligently continued actions to cure such default).

11.3 Termination by Skye.

11.6 Effect of Termination. Upon termination, relinquishment or expiration of this Agreement the Parties hereto shall have no further obligations towards each other, except the fulfillment of obligations that have accrued before the date of termination or expiration.

This Agreement shall not be assignable by either Party without the prior written consent of the other Party, which consent shall not be unreasonable withheld, except that either Party may assign its rights and transfer its duties under this Agreement in whole or in part to any of its Affiliates or in the event of such Party’s merger, consolidation or sale of all or substantially all of its assets or a sale of the division or portion of the business of such Party to which the Product relates, in which case such Affiliate or assignee shall thereafter be substituted directly for such Party hereunder. In connection with any such assignment, the assigning Parry hereby unconditionally guarantees the performance of any of its Affiliates or assignees hereunder. In the event of a breach by an Affiliate or assignee in the observance of applicable terms of this Agreement, the non-assigning Party may proceed against the assigning Party and/or such Affiliate or assignee in order to enforce this Agreement. No assignment and transfer shall be valid or effective unless done in accordance with this Section 12 and unless and until the assignee, transferee or successor-in-interest shall agree in writing to be bound by the provisions of this Agreement, and upon such agreement, all references herein to the assignor, transferor or predecessor shall be deemed to refer and apply to the assignee, transferee or successor in interest.

13. INDEMNIFICATION.

Enzon shall indemnify and hold Skye and its directors, officers, employees, representatives and agents harmless from and against any and all liabilities, claims, demands, actions, suits, losses, damages, costs and expenses (including reasonable attorney’s fees and disbursements, but excluding any anticipated or actual lost profits or revenues or other special, indirect, incidental or consequential damages), based upon any Third Party claims of death, actual bodily injury or physical property damage: (i) to the extent resulting from Enzon’s handling, storage, promotion, testing, use, marketing, distribution or sale of the Product;

 

-20-


or (ii) otherwise resulting from Enzon’s negligence, willful misconduct or material breach of this Agreement (including, without limitation, of the representations, and warranties hereunder); except to the extent covered by subclause (i) of Section 13.2.

13.2 Indemnification by Skye. Skye shall indemnify and hold Enzon and its directors, officers, employees, representatives and agents harmless from and against any and all liabilities, claims, demands, actions, suits, losses, damages, costs and expenses (including reasonable attorney’s fees and disbursements, but excluding any anticipated or actual lost profits or revenues or other special, indirect, incidental or consequential damages): (i) based upon Third Party claims of death, actual bodily injury or physical property damage (A) to the extent resulting from Skye’s manufacture, handling, storage, packaging and labeling of the Product, or (B) to the extent otherwise resulting from Skye’s negligence, willful misconduct or material breach of this Agreement (including, without limitation, of the representations and warranties hereunder); or (ii) which Enzon may incur, suffer or be required to pay by reason of any patent infringement suit or claim of violation of any patents, trademarks, trade secrets or other intellectual property rights of any Third Party (including but not limited to Paul Capital Partners or any of its affiliates, successors or assigns) brought against Enzon and arising from the manufacture, use or sale of the Product or the use of the Trademark.

13.3 Procedure. In the event that any person entitled to indemnification under this Section 13 (an “Indemnitee”) is seeking such indemnification, such Indemnitee shall inform the other Party (the “Indemnitor”) of the claim as soon as reasonably practicable after such Indemnitee receives notice of such claim, shall permit the Indemnitor to assume direction and control of the defense of the claim (including the sole right to settle it at the sole discretion of the Indemnitor, provided that such settlement provides for the unconditional release of the Indemnitee and does not impose any obligation on the Indemnitee or the other Party) and shall cooperate as requested (at the expense of the Indemnitor) in the defense of the claim.

13.4 Complete Indemnification. As the Parties intend complete indemnification, all costs and expenses incurred by an Indemnitee in connection with enforcement of this Section 13 shall also be reimbursed by the Indemnitor.

14. INSURANCE.

Each Party shall use Commercially Reasonable Efforts to maintain insurance (including general and product liability coverage) and upon such terms (including coverages, deductible limits and self-insured retentions) as is customary for the activities to be conducted by it under this Agreement and is appropriate to cover its indemnification obligations hereunder (provided that product liability coverage shall be with limits of not less than $[**]). Each Party shall furnish to the other Party evidence of such insurance, upon request.

15. ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS.

15.1 Notice to Skye.

15.2 Enforcement. Skye shall have the first right, but not the duty, to institute Infringement actions against Third Parties based on any Skye Technology or Trademark(s) in the Territory.

15.3 Infringement Action by Third Parties. In the event of the institution or threatened institution of any suit by a Third Party against Enzon for infringement of any patent, trademark or other intellectual property right involving the marketing or sale of the Product in the Territory where such infringement claim is a result of the manufacture, use or sale of the Product, Enzon shall promptly notify Skye in writing of such suit. Skye agrees to indemnify and defend Enzon as more fully set forth in Section 13 hereof.

16. LIMITATION ON LIABILITY.

NOTWITHSTANDING ANY OTHER PROVISION OF THE AGREEMENT, NO PARTY SHALL BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT OR CONSEQUENTIAL DAMAGES HEREUNDER, SUCH AS LOSS OF REVENUE OR ANTICIPATED PROFITS OR LOST BUSINESS, REGARDLESS OF WHETHER SUCH PARTY HAS NOTICE OR KNOWLEDGE THEREOF, AND NO PARTY SHALL BE LIABLE FOR ANY SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES HEREUNDER: EXCEPT WITH RESPECT TO ITS INDEMNIFICATION OBLIGATIONS UNDER SECTION 13.

17. DISPUTE RESOLUTION.

17.1 Referral to Executive Officers. The Parties recognize that disputes, as to certain matters may from time to time arise during the Term which relate to a Party’s rights and/or obligations hereunder.

The Executive Officers shall meet promptly to negotiate in good faith the matter referred and to determine a resolution. During such period of negotiations, any applicable time periods under this Agreement shall be tolled, if the Executive Officers are unable to determine a resolution in a timely manner, which shall in no case be more than thirty (30) days after the matter was referred to them, the matter shall be resolved through arbitration in accordance with the provisions set forth in Section 17.2, upon notice by either Party to the other specifically requesting such arbitration.

 

-22-


17.2 Arbitration. Any dispute arising out of or relating to any provisions of this Agreement shall be finally settled by arbitration to be held in New York, New York, under the auspices and then current Commercial Arbitration Rules of the American Arbitration Association (the “AAA”). The arbitration shall be conducted by one arbitrator who is knowledgeable in the subject matter which is at issue in the dispute and who is selected by mutual agreement of the Parties or, failing such agreement, shall be selected according to the AAA rules. The Parties shall have such discovery rights as the arbitrator may allow, but in no event broader than that discovery permitted under the Federal Rules of Civil Procedure, in conducting the arbitration, the arbitrator(s) shall apply the New York Rules of Evidence and shall be able to decree any and all relief of an equitable nature, including but not limited to such relief as a temporary restraining order, a preliminary injunction, a permanent injunction, or replevin of property, as well as specific performance. The arbitrator(s) shall also be able to award direct damages but shall not award any other form of damages (e.g., consequential, punitive or exemplary damages). The reasonable fees and expenses of the arbitrator(s), along with the reasonable legal fees and expenses of the Parties (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: (i) if the arbitrator(s) rule in favor of one Party on all disputed issues in the arbitration, the losing Party shall pay one hundred percent (100%) of such fees and expenses; if the arbitrator(s) rule in favor of one Party on some issues and the other Party on other issues, the arbitrators shall issue with the rulings a written determination as to how such fees and expenses shall be allocated between the Parties. The decision of the arbitrators shall be final and may be entered, sued on or enforced by the Party in whose favor it runs in any court of competent jurisdiction at the option of such Party. Whether a claim, dispute or other matter in question would be barred by the applicable statute of limitations, which statute of limitations also shall apply to any claim or disputes subject to arbitration under this Section 17, shall be determined by binding arbitration pursuant to this Section 17.2.

17.3 Injunctive Relief. Notwithstanding the foregoing, nothing contained herein shall prohibit a Party from seeking injunctive relief from a court of competent jurisdiction in the event of a breach or prospective breach of this Agreement by the other Party which would cause irreparable harm to the Non-breaching Party.

18. FORCE MAJEURE.

Any delay in the performance of any of the duties or obligations of either Party hereto (except the payment of money due hereunder) shall not be considered a breach of this Agreement, and the time required for performance shall be extended for a period equal to the period of such delay, if such delay has been caused by or is the result of acts of God; acts of public enemy; insurrections; riots; injunctions; embargoes; labor disputes, including strikes, lockouts, job actions, or boycotts; fires; explosions; earthquakes; floods; shortages of energy: governmental prohibition or restriction; or other unforeseeable causes beyond the reasonable control and without the fault or negligence of the Party so affected.
