For the sole purpose of verifying the amounts payable to Seller under Section 5.1, Seller shall have the right, no more often than once each calendar year, at Seller's expense to retain an independent, certified public accountant selected by Seller and reasonably acceptable to Buyer, to review such records of Buyer in the location where such records are maintained by Buyer upon reasonable notice and during regular business hours and under obligations of strict confidence. The independent certified public accountant shall disclose to Seller only whether the reports required under Section 5.4 are correct or incorrect, and the specific details concerning any discrepancies. No other information shall be provided to Seller. If such independent certified public accountant concludes that additional amounts were owed during such period, then Buyer shall pay such additional amounts to Seller within thirty (30) days after the date Seller delivers to Buyer such accounting firm's written report so concluding. If such independent certified public accountant concludes that Buyer overpaid amounts due during such period, Buyer shall receive a credit against payment of future amounts due for such overpayment. Should the results of such review result in an increase of more than 5% in any payment due Seller hereunder, Buyer shall be obligated to pay any out-of-pocket expenses incurred by Seller with respect to such review.

Within ninety (90) days after the end of each calendar quarter, Buyer shall (i) deliver or cause to be delivered to Seller a true and accurate report, giving such particulars of the business conducted by Buyer, Buyer's Affiliates and any Sublicensees during such quarter under this Agreement as are pertinent to an accounting for any payments hereunder, and (ii) pay or cause to be paid any payment amounts determined on the basis of such accounting. If no payments are due, it shall be so reported. For the purposes of determining when the sale of an ECT Product occurs for the purposes of calculating Net Sales, such sale shall be deemed to occur on the date of invoice to the purchaser of the ECT Product. To the extent appropriate for the calculation of any amounts payable under this Agreement, any such report shall include a statement showing the calculation of the amount owed on a country-by-country basis, the total Net Sales on a country-by-country basis for the period covered, the exchange rate used to convert any amounts payable into United States Dollars and the total Net Sales for the period covered in all countries. 5.5. FORM OF PAYMENT. All amounts payable to Seller hereunder shall be payable in United States dollars to the address specified in Section 17, or at such other place as Seller may reasonably designate; PROVIDED, HOWEVER, that if the law of any foreign country prevents any payment payable to Seller hereunder to be made as so provided, or prevents any such payment to be made in United States dollars, Seller agrees to accept such payment in such form and place as is permitted, including deposits by Buyer in the applicable foreign currency in a local bank or banks in such country designated by Seller. If any currency conversion is required in connection with any payment to Seller hereunder, such conversion shall be made at the buying rate for the transfer of such other currency as quoted by The Wall Street Journal on the last business day of the applicable accounting period, in the case of any payment payable with respect to a specified 10 <PAGE> accounting period, or, in the case of any other payment, the last business day prior to the date of such payment. 5.6. TAXES. Seller and Buyer shall use all reasonable and legal efforts to reduce tax withholding on payments made to Seller hereunder. If Buyer concludes that, notwithstanding such efforts, tax withholding under the laws of any country is required with respect to any payment to be made to Seller under this agreement, Buyer shall withhold or cause its Affiliate or Sublicensee to withhold the required amount and to pay such amount to the appropriate governmental authority. In such a case, Buyer will promptly provide Seller with, or promptly cause Seller to be provided with, original receipts or other evidence sufficient to allow Seller to obtain the benefits of any such tax withholding. 5.7. INTEREST. In the event that any payment due hereunder is not made when due, the payment shall accrue interest beginning on the first day following the calendar quarter to which such payment relates calculated at the annual rate of the sum of (a) [****] percent [**] plus (b) [***********]; PROVIDED, THAT, in no event shall said annual rate exceed the maximum interest rate permitted by law in regard to such payments. Such payment when made shall be accompanied by all interest so accrued. Said interest and the payment and acceptance thereof shall not negate or waive the right of Seller to any other remedy, legal or equitable, to which it may be entitled because of the delinquency of the payment. 6. PROTECTION OF INTELLECTUAL PROPERTY RIGHTS. 6.1. PATENT PROSECUTION/PATENT COSTS. Buyer shall be responsible for prosecuting and maintaining all ECT Patents. Buyer shall reimburse Seller for all reasonable out-of-pocket costs incurred by Seller (if any) after the Effective Date in connection with the preparation, filing, prosecution and maintenance of any ECT Patent. Seller shall cooperate with Buyer in regard to such maintenance and prosecution which cooperation shall include: (i) provision of written or other information reasonably requested by the Buyer, (ii) allowing the Buyer reasonable access to employees of the Seller and (iii) commercially reasonable efforts to have the officers, employees, consultants, agents, accountants and attorneys of the Seller cooperate fully with the Buyer, including, without limitation, by providing written or oral testimony pertaining to the ECT Technology and/or the discovery thereof as reasonably requested by the Buyer, signing all lawful documents reasonably requested by the Buyer, and executing all divisional, continuing, reissue and foreign applications reasonably requested by the Buyer. The Buyer shall reimburse Seller for reasonable out-of-pocket costs incurred in providing such cooperation. Should Buyer determine to abandon prosecution of, or to cease to maintain, any ECT Patent in any jurisdiction, Buyer shall so notify Seller and shall permit Seller, should Seller choose to do so, at Seller's expense, to continue to prosecute and maintain such ECT Patent in such jurisdiction, and Buyer shall cooperate with Seller in regard thereto. In such event, and upon Seller's written request and agreement to indemnification and insurance provisions acceptable to Buyer's insurance carrier, Buyer shall irrevocably assign Buyer's interests in such ECT Patent in such jurisdiction to Seller to the extent Buyer is permitted to do so pursuant to Buyer's contractual obligations to a Third Party or obligations to the U.S. government; PROVIDED, THAT any such assignment shall be subject to the grant of an irrevocable, royalty-free, transferable license under such ECT Patent to the Buyer in the applicable jurisdiction. * This confidential portion has been omitted and filed separately with the Commission. 11 <PAGE> 6.2. CONFIDENTIAL INFORMATION. Each party shall maintain the Confidential Information of the other party in strict confidence, and shall not disclose, divulge or otherwise communicate such Confidential Information to others, or use it for any purpose, except pursuant to, and in order to carry out, the terms and objectives of this Agreement or with the express written consent of the Disclosing Party. Each party also hereby agrees to take reasonable steps to prevent and restrain the unauthorized disclosure of such Confidential Information by any of its directors, officers, employees, consultants, sub-contractors, sub-licensees or agents. For purposes of this Agreement, the ECT Technology and the Assigned Agreements shall become the Confidential Information of Buyer upon the Closing; PROVIDED, HOWEVER, that upon the occurrence of a Reversion Event, the Current ECT Technology and the Assigned Agreements shall become the Confidential Information of Seller. The provisions of this paragraph shall not apply to any Confidential Information of the Disclosing Party which is required to be disclosed by the Receiving Party to comply with any applicable laws or regulations, but only to the extent required by such law or regulation; and FURTHER, PROVIDED, that the Receiving Party making a disclosure pursuant to the provisions of this sentence shall provide prior notice of such disclosure to the Disclosing Party sufficiently in advance of such disclosure to allow the Disclosing Party to respond and to take reasonable and lawful action to avoid and/or minimize the degree of such disclosure. 6.3. ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS. 6.3.1. If Buyer becomes aware of any infringement of any ECT Patent or any violation of any other intellectual property right contained (i) in the ECT Technology by a Third Party (an "Infringer") during the Development Period, or (ii) in the Vaccine Field or related to a Stem Cell Combination Product by an Infringer during term of this Agreement, Buyer shall so notify Seller. Similarly, if Seller becomes aware of the infringement of any ECT Patent during the term of this Agreement or any other intellectual property right contained in the ECT Technology during the term of this Agreement, Seller shall so notify Buyer. 6.3.2. Buyer shall have the right to protect against any infringement of any ECT Patent or any violation of any other intellectual property right contained in the ECT Technology (any such infringement or violation being referred to herein as an "Infringement") by any Infringer during the term of this Agreement when, in Buyer's sole judgment, such action may be reasonably necessary, proper and justified. If (i) at any time during the Development Period with respect to the ECT Technology, or (ii) at any time during the term of this Agreement with respect to the Vaccine Field or relating to a Stem Cell Combination Product, Seller shall have provided Buyer with written evidence demonstrating prima facie evidence of an Infringement and Seller shall have requested Buyer in writing to take steps to protect against such Infringement, and Buyer has not, within 90 days of the receipt of such evidence and request, either (i) caused such Infringement to terminate, (ii) initiated legal proceedings against the Infringer, or (iii) entered into discussions with such alleged Infringer regarding a license under the applicable ECT Patent, then Seller may, upon notice to Buyer, initiate legal proceedings against the Infringer at Seller's expense and in Buyer's name if so required by law. 12 <PAGE> 6.3.3. In the event that either party shall initiate or carry on legal proceedings against any Infringer as contemplated by Section 6.3.2 above, the other party shall fully cooperate with and supply all assistance reasonably required by the party initiating or carrying on such proceedings. The party which initiates any such proceedings shall have sole control of such proceedings and shall bear the reasonable expenses (excluding all legal fees) incurred by the other party in providing such assistance and cooperation as is requested pursuant to this Section 6.3.3. The party initiating or carrying out such proceedings shall keep the other party informed of the progress of such proceedings and such other party shall be entitled to counsel in such proceedings but at its own expense. 6.3.4. Any award paid by any Third Party as a result of such proceedings (whether by way of settlement or otherwise) shall be first applied to reimbursement of the unreimbursed legal fees and expenses incurred by the party initiating the proceedings, then to the reimbursement of the unreimbursed legal fees and expenses incurred by the other party, and then the remainder shall be divided by the parties as follows: 6.3.4.1. If the remaining amount awarded is with respect to lost profits, the applicable party shall receive an amount equal to the damages the court determines such party has suffered as a result of the Infringement, less any amounts (if any) that would have been due to the other party under this Agreement had such party made the sale of products or realized payments from Affiliates or sublicensees that would have resulted in such profits; and the other party shall receive an amount equal to such deducted amounts. 6.3.4.2. Any remaining amounts shall be retained by the party initiating such proceedings. 7. COVENANTS OF BUYER. 7.1. DUE DILIGENCE. 7.1.1. GENERAL OBLIGATION. Buyer shall use commercially reasonable efforts to diligently commercialize the ECT Technology, which efforts shall not be less than the efforts expended by Buyer in connection with its other development projects having similar market potential. 7.1.2.

REPORTS. During the Development Period, Buyer shall provide to Seller a semi-annual report of its activities and efforts toward commercialization of the ECT Technology in sufficient detail to allow Seller to monitor Buyer's compliance with the due diligence obligations set forth in Section 7.1.2 above. Any such reports shall be the Confidential Information of Buyer and shall be held in strict confidence by Seller in accordance with the provisions of Section 6.2 hereof. 7.1.5. EFFECT OF REVERSION OF ECT TECHNOLOGY. Upon the occurrence of a Reversion Event, Buyer shall transfer and assign to Seller all of Buyer's right, title and interest in the Current ECT Technology, including, without limitation, the Assigned Agreements.

If Buyer shall have granted licenses or sublicenses (as the case may be) under the ECT Technology prior to the occurrence of a Reversion Event, such licenses and/or sublicenses (as the case may be) shall be assigned to the Seller and otherwise shall remain in full force and effect under the same terms and conditions. Buyer shall take any and all action Seller may reasonably request, at the expense of Seller, to effect the assignments to Seller set forth in this Section 7.1.5. 7.1.6. FORCE MAJEURE. Buyer shall not be deemed to be in breach of its obligations under this Agreement, including without limitation its obligations under Section 7.1.5 above, if such failure or delay is due to natural disasters or any causes beyond its reasonable control, including without limitation delays caused by regulatory agencies or other governmental bodies; PROVIDED, HOWEVER, that in such event, Buyer shall promptly notify Seller in writing of such occurrence, use commercially reasonable best efforts to meet its obligations under this Agreement, notify Seller in writing of the expected duration of such inability to perform and of any developments (or changes therein) that appear likely to affect Buyer's ability to perform any of its obligations hereunder in whole or in part; and provided, further, any time for performance by Buyer hereunder shall be extended by the actual time of delay caused by such occurrence or event. 14 <PAGE> 7.1.7. PAYMENTS BY SELLER. In consideration for the transfer and assignment back to Seller of Buyer's rights in the ECT Technology as provided in Section 7.1.5 above, Seller shall pay Buyer [****] percent [**] of all license fees, equity payments, royalties, revenues or any other payments received by Seller after a Reversion Event in connection with the transfer or other grant of rights under the ECT Technology until such time as Buyer has recovered its entire investment in the acquisition, research and development and protection of the ECT Technology, including without limitation the $3,000,000 acquisition fee paid to Seller pursuant to this Agreement. 7.2. COMPLIANCE WITH LAW. Buyer shall comply with, and shall insure that Buyer's Affiliates and Sublicensees comply with, all government statutes and regulations that relate to ECT Products, including, but not limited to, FDA statutes and regulations and the Export Administration Act of 1979 (50 App. U.S.C. ss.2401 et. seq.), as amended, and the regulations promulgated thereunder, and any applicable similar laws and regulations of any other country. Without limiting the generality of the foregoing, Buyer agrees that all ECT Products used or sold in the United States shall be manufactured substantially in the United States to the extent required by and in compliance with the Federal Patent Policy. 7.3. MARKING. Buyer shall cause all ECT Products sold in the United States to be marked with all applicable U.S. Patent Numbers, to the full extent required by United States law.

Buyer shall provide Seller with written notice at least fifteen (15) days prior to the cancellation, non-renewal or material change in such insurance; if Buyer does not obtain replacement insurance providing comparable coverage within such fifteen (15) day period, Seller shall have the right to terminate this Agreement effective at the end of such fifteen (15) day period without notice of any additional waiting periods. 13.1.3. Buyer shall maintain such commercial general liability insurance during (a) the period that any such product, process or service is being commercially distributed or sold 24 <PAGE> (other than for the purpose of obtaining regulatory approvals) by Buyer or by a Sublicensee and (b) a reasonable period after the period referred to in (iii)(a) above which in no event shall be less than three (3) years. 13.2. INSURANCE OBLIGATIONS OF SELLER. 13.2.1 Beginning at the time as any Vaccine Product or Stem Cell Combination Product is being commercially distributed or sold (other than for the purpose of obtaining regulatory approvals) by Seller, an Affiliate of Seller or by a Sublicensee of Seller, Seller shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $2,000,000 per incident and $2,000,000 annual aggregate and naming the Buyer Indemnitees as additional insureds. Such commercial general liability insurance shall provide (a) product liability coverage and (b) contractual liability coverage for Seller's indemnification under Section 12 of this Agreement. If Seller elects to self-insure all or part of the limits described above (including deductibles or retentions which are in excess of $250,000 annual aggregate) such self-insurance program must be acceptable to Buyer. The minimum amount of insurance coverage required under this Section 13.2 shall not be construed to create a limit of Buyer liability with respect to its indemnification under Section 12 of this Agreement. 13.2.2. Seller shall provide buyer with written evidence of such insurance upon request of Buyer. Seller shall provide Buyer with written notice at least fifteen (15) days prior to the cancellation, non-renewal or material change in such insurance; if Seller does not obtain replacement insurance providing comparable coverage within such fifteen (15) day period, Buyer shall have the right to terminate this Agreement effective at the end of such fifteen (15) day period without notice of any additional waiting periods. 13.2.3. Seller shall maintain such commercial general liability insurance during (a) 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 Seller or by a Sublicensee and (b) a reasonable period after the period referred to in (iii)(a) above which in no event shall be less than three (3) years. 14.

GOVERNING LAW, VENUE. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware. Each of the parties hereto hereby irrevocably and unconditionally consents to submit to the exclusive jurisdiction of the courts of the State of Delaware and of the United States of America located in the State of Delaware for any actions, suits or proceedings arising out of or relating to this Agreement and the transactions contemplated hereby, and each of the parties hereto agrees not to commence any action, suit or proceeding relating hereto or thereto except in such courts. Each of the parties hereto hereby irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby or thereby, in the courts of the State of Delaware or the United States of America located in the State of Delaware, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. 27 <PAGE> 21. DISPUTE RESOLUTION. Any controversy, dispute or claim arising out of or in connection with this Agreement, or the breach, termination or validity hereof, shall be settled by final and binding arbitration to be conducted by an arbitration tribunal in Wilmington, Delaware pursuant to the Commercial Arbitration Rules of the American Arbitration Association then in effect. The arbitration tribunal shall consist of three arbitrators. The party initiating arbitration shall nominate one arbitrator in the request for arbitration and the other party shall nominate a second in the answer thereto within thirty (30) days of receipt of the request. The two arbitrators so named will then jointly appoint the third arbitrator. If the answering party fails to nominate its arbitrator within the thirty (30) day period, or if the arbitrators named by the parties fail to agree on the third arbitrator within sixty (60) days, the office of the American Arbitration Association in Wilmington, Delaware shall make the necessary appointments of such arbitrator(s). Each party shall pay the costs of its respective arbitrator, and the parties shall share equally the costs of the third arbitrator. The decision or award of the arbitration tribunal (by a majority determination, or if there is no majority, then by the determination of the third arbitrator, if any) shall be final, and judgment upon such decision or award may be entered in any competent court or application may be made to any competent court for judicial acceptance of such decision or award and an order of enforcement. In the event of any procedural matter not covered by the aforesaid rules, the procedural law of The State of Delaware shall govern. 22. INDEPENDENT CONTRACTORS. For the purposes of this Agreement and all services to be provided hereunder, each shall be, and shall be deemed to be, an independent contractor and not an agent, partner, joint venturer or employee of the other party. Neither party shall have authority to make any statements, representations or commitments of any kind, or to take any action which shall be binding on the other party, except as may be explicitly provided for herein or authorized in writing. 23. SEVERABILITY. If any provision of this Agreement shall be found by a court of competent jurisdiction to be void, invalid or unenforceable in any respect in the jurisdiction or jurisdictions in which it is to be performed, the same shall either be reformed to comply with applicable law or stricken if not so conformable, so as not to affect the validity or enforceability of this Agreement; and no party shall be deemed to be in breach of this Agreement for its failure to perform any obligation which is unenforceable, void or invalid. 24. NO WAIVER. No failure or delay by a party hereto in exercising any right, power or remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of the party. No single or partial exercise of any right, power or remedy under this Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue 28 <PAGE> other available remedies. The terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other terms or provisions of this Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent. 25. COUNTERPARTS. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original for all purposes and all of which together shall constitute one and the same instrument. 26. HEADINGS.
