CMCC agrees that LICENSEE 5 <PAGE> 7 shall have complete control of all regulatory submissions of Licensed Products to the appropriate regulatory agencies worldwide.

Only one payment will be made for each of the milestones recited under 3.1.1, 3.1.2, 3.1.3 and 3.1.4. Due diligence shall be demonstrated by attaining the following milestones: 3.1.1 -within 5 years of the Effective Date, the filing of an IND in the U.S. for a Licensed Product by LICENSEE; 3.1.2 -within 6.5 years of the Effective Date, the initiation of Phase II trials of a Licensed Product; 3.1.3 -within 8.5 years of the Effective Date, the initiation of Phase III trials of a Licensed Product; and 3.1.4 -within 11 years of the Effective Date, the submission of an NDA or similar application to gain regulatory approval for the marketing of a Licensed Product; and by continuing sponsorship of related preclinical studies at Children's Hospital, if appropriate. 3.2 LICENSEE acknowledges that, prior to attaining the first milestone of 3.1.1 above, additional activities must be undertaken including but not limited to: 1) development of a plan describing the scientific and technical goals to be accomplished prior to attaining the milestone of 3.1.1 and allocation the LICENSEE resources, either internal or contracted, that will be applied in accomplishing those goals, 2) confirmation of the antitumor activity of one or more Licensed Products in one or more animal models, 3) development of processes for manufacturing one or more Licensed Products on a scale capable of producing sufficient material for testing and evaluation, 4) conduct of preclinical toxicology and pharmacology studies, and 4) determination of whether Licensee or a sublicense will be initiating clinical trials. Licensee agrees to keep CMCC reasonable informed of the additional activities by preparing at least annually a 6 <PAGE> 8 written summary of the activities planned and completed and by holding on at least annually a meeting with CMCC representatives to review progress to date. 3.3 LICENSEE acknowledges that the primary objective of CMCC in entering this License Agreement is to promote the development and marketing of Licensed Products and Processes for the public good. To this end, CMCC shall have the right to terminate this Agreement pursuant to Paragraph 13.3 below if LICENSEE fails to attain any of the above milestones for more than six (6) months after the milestone time period because of business circustances such as merger, acquisition or the like. However, if LICENSEE can demonstrate to the satisfaction of CMCC, at CMCC's sole discretion, that circumstances beyond LICENSEE's control precluded LICENSEE from fulfilling its diligence obligations, and that it is unlikely that any third party could overcome these circumstances better than LICENSEE, then CMCC shall not exercise its termination rights under this Article for one year from the date on which CMCC give notice of termination and if LICENSEE reestablishes diligence towards it objectives during this one year period, any prior lack of diligence will be deemed cured.

Said books and the supporting data shall be open at all reasonable times for five (5) years following the end of the calendar year to which they pertain, to the inspection of CMCC or its agents for the purpose of verifying LICENSEE's royalty statement or compliance in other respects with this Agreement. CMCC can request auditing of said books and supporting data no more than once each calendar year. 5.2. LICENSEE, within forty-five (45) days after the initial sale or sublicense of the product on March 31, June 30, September 30 and December 31, of each year, shall deliver to CMCC true and accurate reports, giving such particulars of the business conducted by LICENSEE and its sublicensees during the preceding three month period under this Agreement as shall be pertinent to a royalty accounting hereunder.

The payment of such interest shall not foreclose CMCC from exercising any other rights it may have as a consequence of the lateness of any payment. 9 <PAGE> 11 ARTICLE VI -- PATENT PROSECUTION 6.1 CMCC and LICENSEE shall apply for, seek prompt issuance of, and maintain during the term of this Agreement the Patent Rights set forth in Appendix A. The prosecution, filing and maintenance of all Patent Rights Patents and Applications shall be the primary responsibility of LICENSEE; with appropriate and timely review and approval by CMCC. LICENSEE shall solicit CMCC's comment prior to any significant actions required during filing, prosecution, and maintenance and provide CMCC with drafts of proposed actions and responses in advance and file copies after the action is completed. If CMCC elects to consult with patent attorneys more than is considered necessary and reasonable by LICENSEE, such consultation shall be at CMCCGs expense. 6.2 Payment of all fees and costs relating to the filing, prosecution, and maintenance of the Patent Rights shall be the responsibility of LICENSEE, whether such fees and costs were incurred before or after the date of this Agreement. ARTICLE VII - INFRINGEMENT 7.1 LICENSEE shall inform CMCC promptly in writing of any alleged infringement of the Patent Rights by a third party and of any available evidence thereof. 7.2 If at any time during the term of this Agreement, LICENSEE furnishes to CMCC reasonably convincing written evidence of an infringement of a patent included in the Patent Rights covering the Inventions which adversely and substantially affects the commercial operations of LICENSEE in the country where the infringement of the patent is occurring, under the license granted hereunder, and CMCC shall within three (3) months after receipt of such evidence (the three month period) fail to cause such infringement to terminate or to bring a suit or action to compel termination, then payment of one half (1/2) the royalties and one half (1/2) minimum amounts which are earned and payable to CMCC on Net Sales by licensee or sublicensees under Article IV hereof shall be waived in the country of the infringement, so long as such infringement continues; provided, however, that such royalties and minimum amounts shall not be waived so long as at least one suit or action is being prosecuted by CMCC for infringement of a patent in the country in which the infringement of the patent is occurring, covering the 10 <PAGE> 12 Inventions. In no event shall such waiver of royalties and minimum amounts exceed 50% of the royalties and minimum amounts payable hereunder. 7.3 If after the three month period, CMCC fails to cause such infringement to terminate or to bring a suit or action to compel termination, LICENSEE shall have the right, but not the obligation, to bring such suit or action to compel termination at LICENSEE's expense. CMCC independently shall have the right to join any such suit or action brought by LICENSEE and, in such event. No settlement, consent judgment or other voluntary final disposition of the suit may be entered into without the consent of CMCC which consent shall not unreasonably be withheld. Any damages recovered by suit or action shall be first used to reimburse each party hereto for the cost of such suit or action (including attorney's fees) actually paid by each party hereto as the case may be, then to reimburse CMCC for any royalties and minimum royalties waived under this Section 7.3 and the residue, if any, shall be belong to the party responsible for the prosecution of the suit. 7.4 In the event that LICENSEE shall undertake the enforcement and/or defense of the Patent Rights by litigation, LICENSEE may withhold up to fifty percent (50%) of the royalties otherwise thereafter due CMCC hereunder and apply the same toward reimbursement of its expenses, including reasonable attorneys' fees, in connection therewith. Any recovery of damages by LICENSEE for any such suit shall be applied first in satisfaction of any unreimbursed expenses and legal fees of LICENSEE relating to the suit, next toward reimbursement of CMCC for any royalties past due or withheld and applied pursuant to this Article VII, and to royalties due to CMCC for infringing sales as if sales had been made by LICENSEE. The balance remaining from any such recovery shall belong to LICENSEE. 7.5 In the event that a declaratory judgment action alleging invalidity or non-infringement of any of the Patent Rights shall be brought against LICENSEE, CMCC, at its option, shall have the right, within thirty (30) days after commencement of such action, to intervene and take over the sole defense of the action at its own expense. 11 <PAGE> 13 7.6 If, for any reason, LICENSEE should choose not undertake the enforcement and/or defense of the Patent Rights by litigation after the three month period, CMCC shall have the right, but not the obligation, to prosecute, at its own expense, any such infringements of the Patent Rights and, in furtherance of such right, CMCC hereby agrees that LICENSEE may join CMCC as a party plaintiff in any such suit, without expense to LICENSEE. The total cost of any such infringement action commenced or defended solely by CMCC shall be borne by CMCC and CMCC shall keep any recovery or damages for past infringement derived therefrom. 7.7 In any infringement suit as either party may institute to enforce the Patent Rights pursuant to this Agreement, the other party hereto shall, at the request and the expense of the party initiating such suit, cooperate in all respects and, to the extent possible, have its employees testify when requested and make available relevant records, papers, information, samples, specimens, and the like. 7.8 LICENSEE, during the period of this Agreement, shall have the sole right in accordance with the terms and conditions herein to sublicense any alleged infringer for future use of the Patent Rights. ARTICLE VIII - INDEMNIFICATION, PRODUCT LIABILITY AND INSURANCE 8.1. Indemnification 8.1.1 LICENSEE shall indemnify, defend and hold harmless CMCC and its trustees, officers, medical and professional staff, employees, and agents and their respective successors, heirs and assigns (the "Indemnitees"), against any liability, damage, loss or expense (including reasonable attorney's fees and expenses of litigation) incurred by or imposed upon the Indemnitees or any one of them in connection with any claims, suits, actions, demands or judgments arising out of any theory of product liability (including, but not limited to, actions in the form of tort, warranty, or strict liability) concerning any product, process or service made, used or sold pursuant to any right or license granted under this Agreement. 12 <PAGE> 14 8.1.2 LICENSEE's indemnification under (a) above shall not apply to any liability, damage, loss or expense to the extent that it is directly attributable to the negligent activities, reckless misconduct or intentional misconduct of the Indemnitees. 8.1.3 LICENSEE agrees, at its own expense, to provide attorneys reasonably acceptable to CMCC to defend against any actions brought or filed against any party indemnified hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought. 8.1.4 CMCC shall indemnify, defend and hold harmless Licensee for any damage, loss or expense to the extent that it is directly attributable to the negligent activities, reckless misconduct, or intentional misconduct of the employees or subcontractors of CMCC. 8.1.5 This Section 8.1 shall survive expiration or termination of this Agreement. 8.2. Insurance 8.2.1 Beginning at the time as any such product, process or service is being commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by LICENSEE or by a sublicensee, affiliate or agent of LICENSEE, LICENSEE shall, at its sole cost and expense, procure and maintain comprehensive general liability insurance in amounts not less than $2,000,000 per incident and $2,000,000 annual aggregate and naming the Indemnitees as additional insureds. Such comprehensive general liability insurance shall provide 18.104.22.168 product liability coverage and 22.214.171.124 broad form contractual liability coverage for LICENSEE's indemnification under Section 8.1 of this Agreement. If LICENSEE elects to selfinsure all or part of the limits described 13 <PAGE> 15 above (including deductibles or retentions which are in excess of $250,000 annual aggregate) such self-insurance program must be acceptable to the CMCC and the Risk Management Foundation of the Harvard Medical Institutions, Inc. The minimum amount of insurance coverage required under this Section 8.2 shall not be construed to create a limit of LICENSEE's liability with respect to its indemnification under Section 8.1 of this Agreement. 8.2.2 LICENSEE shall provide CMCC with written evidence of such insurance upon request of CMCC. LICENSEE shall provide CMCC with written notice at lease forty-five (45) days prior to any material change in such insurance. If the insurnace is canceled and if LICENSEE does not obtain replacement insurance providing comparable coverage within such forty-five (45) day period, CMCC shall have the right to terminate this Agreement effective at the end of such forty-five (45) day period after providing notice of CMCC's intent to do so. 8.2.3 LICENSEE shall maintain such comprehensive general liability insurance during 126.96.36.199 the period that any such product, process or service is being commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by LICENSEE or by a sublicensee, affiliate or agent of LICENSEE, and 188.8.131.52 a reasonable period after the period referred to in 184.108.40.206 above which in no event shall be less than five (5) years. 8.2.4 This ARTICLE 8.2 shall survive expiration or termination of this Agreement. 14 <PAGE> 16 ARTICLE IX -- EXPORT CONTROLS It is understood that CMCC is subject to United States laws and regulations controlling the export of technical data, computer software, laboratory prototypes and other commodities (including the Arms Export Control Act, as amended and the Export Administration Act of 1979), and that its obligations hereunder are contingent on compliance with applicable United States export laws and regulations. The transfer of certain technical data and commodities may require a license from the cognizant agency of the United States Government and/or written assurances by LICENSEE that LICENSEE shall not export data or commodities to certain foreign countries without prior approval of such agency. CMCC neither represents that a license shall not be required nor that, if required, it shall be issued. ARTICLE X -- NON-USE OF NAMES LICENSEE shall not use the names of the Children's Medical Center Corporation nor of any of its employees, nor any adaptation thereof, in any advertising, promotional or sales literature without prior written consent obtained from CMCC in each case except that LICENSEE may state that it is licensed by CMCC under one or more of the patents and/or applications comprising the Patent Rights, and LICENSEE may comply with disclosure requirements of all applicable laws relating to its business, including United States and state security laws. ARTICLE XI -- ASSIGNMENT Subject to the restrictions set forth herein, this Agreement, and each and every provision hereof, shall be binding upon and shall inure to the benefit of the parties, their respective successors, successors-in-title, heirs and assigns, and each and every successor-in-interest to any party, whether such successor acquires such interest by way of gift, inheritance, purchase, foreclosure, or by any other method, shall hold such interest subject to all the terms and provisions of this Agreement; provided however that LICENSEE shall not assign or transfer the whole or any part of this Agreement or its rights hereunder without the express written agreement of CMCC which agreement shall not be unreasonably withheld. 15 <PAGE> 17 ARTICLE XII -- ARBITRATION 12.1 Any and all claims, disputes or controversies arising under, out of, or in connection with this Agreement, which have not been resolved by good faith negotiations between the parties, shall be resolved by final and binding arbitration in Boston, Massachusetts, under patent arbitration rules of the American Arbitration Association then obtaining. The arbitrators shall have no power to add to, subtract from or modify any of the terms or conditions of this Agreement. Any award rendered in such arbitration may be enforced by either party in either the courts of the Commonwealth of Massachusetts or in the United States District Court for the District of Massachusetts, to whose jurisdiction for such purposes CMCC and LICENSEE each hereby irrevocably consents and submits. 12.2 Notwithstanding the foregoing, nothing in this Article shall be construed to waive any rights or timely performance of any obligations existing under this Agreement. ARTICLE XIII -- TERM AND TERMINATION 13.1 Unless earlier terminated as hereinafter provided, this Agreement shall remain in full force and effect for the life of the last to expire patent issued under the Patent Rights. 13.2 If LICENSEE shall cease to carry on its business, this Agreement shall terminate upon notice by CMCC. 13.3 Should LICENSEE fail to pay CMCC royalties due and payable hereunder, CMCC shall have the right to terminate this Agreement on sixty (60) days' notice, unless LICENSEE shall pay CMCC within the sixty (60) day period, all such royalties and interest due and payable. Upon the expiration of the sixty (60) day period, if LICENSEE shall not have paid all such royalties and interest due and payable, the rights, privileges and license granted hereunder shall terminate. 13.4 Upon any material breach or default of this Agreement by LICENSEE, other than those occurrences set out in Paragraphs 13.2 and 13.3 herein above, which shall always take precedence in that order over any material breach or default referred to in this Paragraph 13.3, CMCC shall have the right to terminate this Agreement 16 <PAGE> 18 and the rights, privileges and license granted hereunder by ninety (90) days' notice to LICENSEE. Such termination shall become effective unless LICENSEE shall have cured any such breach or default prior to the expiration of the ninety (90) day period. 13.5 LICENSEE shall have the right to terminate this Agreement at any time on six (6) months' notice to CMCC, and upon payment of all amounts due CMCC through the effective date of termination. 13.6 Upon termination of this Agreement for any reason, nothing herein shall be construed to release either party from any obligation that matured prior to the effective date of such termination. LICENSEE and any sublicensee thereof may, however, after the effective date of such termination, sell all Licensed Products, and complete Licensed Products in the process of manufacture at the time of such termination and sell the same, provided that LICENSEE shall pay to CMCC the royalties thereon as required by Article IV of this Agreement and shall submit the reports required by Article V hereof on the sales of Licensed Products. 13.7 CMCC agrees that if LICENSEE has provided to CMCC notice that LICENSEE has granted a sublicense to a sublicensee under this Agreement, then in the event CMCC terminates this Agreement for any reason, CMCC shall provide to such sublicensee no less than thirty (30) days prior to the effective date of said termination, written notice of said termination at the address specified by LICENSEE to CMCC in LICENSEE's notice to CMCC under Article XIV. CMCC agrees that upon the sublicensee's notice as described below and provided the sublicensee is not in breach of its sublicense, CMCC shall grant to such sublicensee license rights and terms equivalent to the sublicense rights and terms which the sublicense shall have granted to said sublicensee; provided that the sublicensee shall remain a sublicensee under this Agreement for a period of at least sixty (60) days following receipt of notice from CMCC.
