The Parties expect that such definitive documents will provide that their respective share in milestone and royalty payments from sublicensees will generally be divided equally after deduction of payments required to be made to Third Party Licensors, but will initially be proportionate to the Parties’ respective financial investments in the relevant product development activities, until any disproportionate investment is recouped and an additional premium is paid to the Party that made the greater investment to reflect the associated risk of such activities.  For example, if Eleos expends 60% of the development costs up to the point of entering into a sublicensing agreement, and AVI expends 40% of such costs, then (i) Eleos and AVI would share milestone and royalty revenue from the sublicensee 60%/40% after required Third Party Licensor payments are made until Eleos recovers an additional annually compounded 25% cost of capital premium over its incrementally greater share invested, and (ii) after such recovery the Parties would share sublicense proceeds on a 50%/50% basis.

7.3           Statements of Work.  Statements of Work shall be in writing and shall include, among other things, the detailed research and development plans, timelines, budgets, payment terms, nature of deliverables, project coordination and other terms for the Development Services.  No Statement of Work will become effective unless executed by an authorized representative of each of the Parties.  In the event of a direct conflict between a Statement of Work and a particular term or condition contained in this Agreement, this Agreement shall prevail.  Notwithstanding anything to the contrary above, if a Party performs any services for the other Party under this Section 7 without first entering into an applicable Statement of Work, the terms and conditions of this Agreement shall still govern such services.

8.                                       Steering Committee.

8.1           Steering Committee.  The Parties shall establish a steering committee consisting of two members appointed by AVI and two members appointed by Eleos (the “Steering Committee”).  The Steering Committee shall direct, review and discuss the progress of the Parties’ efforts with respect to joint development activities and such other matters arising under this Agreement as the Parties consider appropriate.  The Steering Committee shall meet at regular meetings to be held approximately every three months.  The Steering Committee shall be responsible for coordinating the creation of Statements of Work and the qualification of the Second Supply Source and other third-party contract manufacturers of API.

8.2           Governance of Steering Committee.  Eleos shall designate a member of the Steering Committee to serve as the chair of the Steering Committee for the calendar year 2007.  Thereafter, a member of the Steering Committee shall be designated by AVI to serve as chair in even-numbered years, and a member designated by Eleos shall serve as chair in odd-numbered years.  The chair shall be responsible for the administration of the Steering Committee, including, without limitation, the scheduling of meetings and the preparation of meeting agendas.  Meetings shall be held at or near the Parties’ locations on an alternating basis or by telephone conference, at the discretion of the Steering Committee chair.  Each Party shall bear its own costs and expenses in connection with all Steering Committee activities.  The actions and decisions of the Steering Committee shall not be binding upon the Parties except as the Parties shall otherwise agree in writing.

8.3           Project Managers.  The Parties shall each appoint a project manager to assume overall responsibility for their respective roles and obligations under this Agreement.  The Parties’ respective project managers will be responsible for coordinating the Parties’ respective joint development activities, including overseeing the performance and quality thereof, participating in (personally or by representative) meetings of the Steering Committee, acting as day-to-day liaisons between the Parties and coordination of the plans called for by Section 5 above.

12

9.                                       Manufacturing.

9.1           Clinical Manufacturing.  AVI will be the preferred supplier to Eleos of cGMP clinical supplies of API, on the terms and conditions provided in a separate Clinical Supply Agreement.

9.2           Second Supply.  Eleos and AVI will qualify a second manufacturing source agreed to by the Parties (the “Second Supply Source”) to manufacture API for Licensed AVI IP Products for clinical and commercial purposes.  Eleos will develop qualification criteria and procedures in consultation with AVI, and the Parties will cooperate to implement those criteria and procedures.  As part of qualification, the Second Supply Source will produce at least one batch of cGMP API for manufacturing comparability testing and clinical use.  Eleos will be responsible for conducting the comparability testing and will require API batch production records for all API batches in order to submit CMC filings to the FDA for its INDs and other equivalent regulatory filings in foreign countries.  AVI will provide the Second Supply Source with such materials and information as are necessary to enable the Second Supply Source to manufacture API as required by Eleos, including training conducted in AVI facilities and written materials provided in full within one-hundred twenty (120) days of reasonable requests for information by Eleos or the Second Supply Source.  The Second Supply Source will be required to sign a suitable Non-Disclosure Agreement acceptable to the Parties that provides for the maintenance of confidentiality of AVI Intellectual Property and appropriate restrictions on its use.

9.3           AVI Option for Commercial Manufacturing.

(a)      To commence commercial manufacturing of API for Licensed AVI IP Products, Eleos shall request AVI to provide a quotation for the manufacture of three batches of the API subject to specifications provided by Eleos.  AVI shall have a 30-day period to review the request and provide a quotation.  If the AVI quotation is acceptable to Eleos and AVI demonstrates to Eleos’ reasonable satisfaction that AVI has the capability to manufacture to Eleos’ requirements, including quality, quantity, cost, purchase price and delivery, and to meet all applicable regulatory requirements including passing FDA inspection demonstrating AVI’s capability to manufacture commercial API under cGMP as a licensed pharmaceutical manufacturing facility, then the Parties will use their best efforts to negotiate and execute a separate Commercial Supply Agreement on commercially reasonable terms under which Eleos will purchase up to one kilogram per year of commercial API from AVI.  The Parties agree that the purchase price payable by Eleos for API will be *****% of AVI’s fully-burdened manufacturing cost, reflecting an appropriate allocation of indirect costs.  The Commercial Supply Agreement would provide that if AVI is willing and capable of supplying commercial quantities of API in excess of one kilogram per year to Eleos, Eleos would have the right to purchase up to *****% of its commercial needs above one kilogram/year from the Second Supply Source.  Earned royalties payable on Net Sales of commercial API manufactured by the Second Supply Source or other contract manufacturer under these circumstances will be calculated at the *****% rate of Section 4.3(a).  If AVI thereafter fails to meet its obligations to Eleos under the Commercial Supply Agreement, earned royalties payable on Net Sales of commercial API manufactured by the Second Supply Source or other contract manufacturer will be calculated at the *****% rate of Section 4.3(b).

(b)      If AVI does not provide a quotation within the 30-day period or is unwilling or unable to manufacture API for any Licensed AVI IP Product as required by Eleos, Eleos will be free to obtain API from the Second Supply Source or any other mutually-acceptable contract manufacturer, with AVI’s consent not to be unreasonably withheld, and AVI will provide the contract manufacturer with materials, information and training as provided for the Second Supply Source in Section 9.2.  Any such contract manufacturer will be required to sign

13

a suitable Non-Disclosure Agreement acceptable to the Parties that provides for the maintenance of confidentiality of AVI Intellectual Property and appropriate restrictions on its use.  If the contract manufacturer is one to which AVI has not previously conveyed its manufacturing processes for the API, Eleos will reimburse AVI *****% of AVI’s fully-burdened cost of transferring the manufacturing process to the contract manufacturer.  In this case earned royalties payable on Net Sales of commercial API manufactured by the Second Supply Source or other contract manufacturer will be calculated at the *****% rate of Section 4.3(b).

10.                                 Intellectual Property.

10.1         Existing Intellectual Property.  This Agreement gives AVI no ownership rights in the Eleos Intellectual Property in existence as of the Effective Date and gives Eleos no ownership rights in the AVI Intellectual Property in existence as of the Effective Date.

10.2         Newly Created Intellectual Property.  During the term of this Agreement, the Parties anticipate that Intellectual Property may be created by one or both of the Parties hereto and in furtherance of performance under this Agreement (“Newly Created Intellectual Property”).  Ownership and use rights for Newly Created Intellectual Property will be as follows:

(a)      Inventorship.  Inventorship of Newly Created Intellectual Property shall be determined in accordance with the patent laws of the United States.

(b)      Ownership.  Newly Created Intellectual Property relating solely to AVI Intellectual Property shall constitute AVI Intellectual Property and shall be owned by AVI.  Newly Created Intellectual Property relating solely to Eleos Intellectual Property shall constitute Eleos Intellectual Property and shall be owned by Eleos.  Newly Created Intellectual Property that relates to both AVI Intellectual Property and Eleos Intellectual Property shall be owned by the Party within whose Field the subject matter of the Newly Created Intellectual Property falls.  Newly Created Intellectual Property that relates to both AVI Intellectual Property and Eleos Intellectual Property and the subject matter of which falls into both the AVI Field and the Eleos Field shall be deemed to be jointly owned (“Jointly Owned Intellectual Property”).  AVI and Eleos agree to execute the necessary documents (e.g., assignments) to convey ownership rights in the Newly Created Intellectual Property from one Party to the other in keeping with the parameters set forth above.  Newly Created Intellectual Property which, under the terms of this Section 10.2(b) is deemed to be AVI Intellectual Property, Eleos Intellectual Property or Jointly Owned Intellectual Property will automatically be included in the subject matter of the license grants of Section 2.

11.                                 Books and Records.

11.1         Each Party (the “Reporting Party”) shall keep, and shall cause its Affiliates and sublicensees to keep, books and records in accordance with generally acceptable accounting principles accurately showing all transactions and information relating to transactions under this Agreement.  Such books and records shall be preserved for at least five (5) years from the date of the entry to which they pertain and shall be open at reasonable times upon reasonable notice no more than once per calendar year for inspection by an independent certified public accountant of national standing satisfactory to the non-Reporting Party.  Such accountant shall have reasonable access to the Reporting Party’s offices and the relevant records, files and books of account, and shall have the right to examine any other records reasonably necessary to determine the accuracy of the calculations provided by the Reporting Party under this Agreement. The accountant shall be required to sign a suitable confidentiality agreement reasonably

14

acceptable to the Parties prior to conducting such audit, and the only Confidential Information of the Reporting Party (and its Affiliates) that the accountant shall be authorized to disclose to the non-Reporting Party will be the results of the accountant’s calculation of royalties payable hereunder and royalties paid hereunder.

11.2         The fees and expenses of the certified public accountant performing such an examination shall be borne by the non-Reporting Party.  However, if an error in payable royalties of more than five percent (5%) of the total royalties due for any year is discovered, or if as a result of the examination it is determined that the Reporting Party is in material breach of its other obligations under this Agreement, then such fees and expenses shall be borne by the Reporting Party, and the Reporting Party shall promptly reimburse the non-Reporting Party for reasonably documented audit expenses as well as all overdue royalty and late interest payments.

12.                                 Term.

12.1         Unless otherwise terminated by operation of law or by one or both of the Parties in accordance with the provisions of this Agreement, this Agreement shall be in force from the Effective Date and shall remain in effect in each country until the expiration of the last-to-expire patent of the Eleos Intellectual Property or the AVI Intellectual Property licensed hereunder having claims covering a Licensed Product sold in such country, or ten (10) years from the date of first commercial sale of a Licensed Product in such country, whichever is later.  After such date of expiration, the license hereunder shall be considered fully paid up and the only obligations shall be as set forth in Section 12.2.

12.2         Any expiration or termination of this Agreement shall not affect the rights and obligations set forth in Sections 11 (Books and Records), 14 (Disposition of Licensed Products), 15 (Use of Names), 18 (Patent Marking), 20 (Indemnification), 27 (Confidentiality) and 28 (Dispute Resolution).

13.                                 Termination.

13.1         Notice of Breach.  If a Party breaches or fails to perform any material provision of this Agreement, the other Party may give written notice of such default, specifying the breach and each country in which the breach is allegedly occurring or whether the breach relates to the entire Agreement (a “Notice of Breach”) to the breaching Party.

13.2         Notice of Termination.  If the breaching Party fails to cure such default within sixty (60) days of the Notice of Breach, the non-breaching Party shall have the right to terminate this Agreement and the licenses herein (i) as to the country/ies where the breach remains uncured (if the breach relates only to certain countries) or (ii) if the breach represents a material portion of the breaching Party’s obligations under this Agreement, then at the non-Breaching Party’s option, as to the breaching Party’s license rights under the entire Agreement.  In order to so terminate, the non-breaching Party shall deliver a second written notice (a “Notice of Termination”) to the breaching Party, if applicable specifying the countries where rights hereunder are being terminated.  If a Notice of Termination is sent to a breaching Party, this Agreement shall automatically terminate on the effective date of such Notice of Termination to the extent of the termination provided for therein.  Termination by a non-breaching Party shall not terminate the license rights and other benefits received by the non-breaching Party under this Agreement, and the obligations of the non-breaching Party that correspond thereto (e.g., to make payments under Section 4, engage in diligence under Section 5, and, in the event Eleos is the non-breaching party, to purchase manufactured API in accordance with Section 9), but shall terminate the non-breaching Party’s obligations regarding product development under Sections 7 and 8.

13.3         Obligation for Amounts Owed.  Termination shall not relieve the breaching Party of its obligation to pay all amounts due to the non-breaching Party as of the effective date of termination and

15

shall not impair any accrued rights of the non-breaching Party.  During the 60-day cure period provided by the foregoing, the Parties shall negotiate in good faith to resolve any dispute relating to any alleged breach of this Agreement.

14.                                 Disposition of Licensed Products and Information on Termination.

14.1         Upon termination of this Agreement by a Party:

(a)     the other Party may complete all partially made Licensed Products and dispose of all previously made Licensed Products, but no more, within a period of one hundred and eighty (180) days after the Notice of Termination; provided, however, that the disposition of such Licensed Products shall be subject to the terms of this Agreement including, but not limited to, the payment of royalties at the rate and at the time provided herein and the delivery of reports thereon; and

(b)     the breaching Party shall promptly return, and shall cause its Affiliates and sublicensees to return, to the other Party all property belonging to the other Party including materials containing Confidential Information of the other Party (except for one copy of such materials which may be retained for record purposes only and which may not be disclosed).

15.                                 Use of Names and Trademarks.

15.1         Nothing contained in this Agreement shall be construed as granting any right to a Party, its Affiliates or sublicensees to use in advertising, publicity or other promotional activities or otherwise any name, trade name, trademark, or other designation of the other Party.

15.2         Subject to Section 15.1 above, a Party may use any name, trade name, trademark, logo or other designation (“Marks”) that it desires with respect to the design, development, manufacture or sale of Licensed Products anywhere in the world.  Each Party shall own all right, title and interest in and to its own Marks, both during and after termination of this Agreement.  No Party shall use, register or attempt to register any Mark that would be confusingly similar to any Mark of the other Party.

16.                                 Representations and Warranties.

17.                                 Patent Prosecution and Maintenance.

17.1         Prosecution.  Eleos shall diligently prosecute and maintain the United States and international patent applications and patents included in the Eleos Intellectual Property using counsel of its choice.  AVI shall diligently prosecute and maintain the United States and international patent applications and patents included in the AVI Intellectual Property using counsel of its choice.  Each Party’s counsel shall consult in good faith with patent counsel for the other Party prior to any material filings or other actions before or communications with the U.S. Patent and Trademark Office and shall promptly provide the other Party with copies of all relevant documentation so that it may be informed of the continuing prosecution.  The receiving Party agrees to keep this documentation confidential.  Each Party’s counsel shall take instructions only from that Party.

17.2         Drafting Consideration.  Eleos shall give due consideration to drafting or amending any patent application included in the Eleos Intellectual Property to include claims reasonably requested by

18

AVI to protect the Licensed Eleos IP Products contemplated to be sold under this Agreement.  AVI shall give due consideration to drafting or amending any patent application included in the AVI Intellectual Property to include claims reasonably requested by Eleos to protect the Licensed AVI IP Products contemplated to be sold under this Agreement.

17.3         Costs.  Eleos shall be responsible for paying all past and future costs, of preparing, filing, prosecuting, defending, and maintaining all United States patent applications and/or patents, including interferences and oppositions, and all corresponding foreign patent applications and patents covered by Eleos Intellectual Property.  AVI shall be responsible for paying all past and future costs, of preparing, filing, prosecuting, defending, and maintaining all United States patent applications and/or patents, including interferences and oppositions, and all corresponding foreign patent applications and patents covered by AVI Intellectual Property.  In addition, for Jointly Owned Intellectual Property Eleos will be responsible for paying for all future costs for inventions as they apply to new p53-PMO compositions of matter and uses thereof with respect to p53 regulation including but not limited to oligonucleotide sequences, and AVI will be responsible for paying for all future costs for other inventions such as drug delivery methods or new compositions of matter not targeting p53 and uses thereof as it applies to PMO technology.  With respect to Jointly Owned Intellectual Property the responsible Party will provide the other Party with all correspondence with patent offices in a timely fashion.  Should the responsible Party elect to forgo any or all available patent rights with respect to a Jointly Owned Invention the other Party shall have the right to take over the prosecution of those rights and pay for all such activity.  The Parties shall mutually share the prosecution strategy and negotiate on a case-by-case basis when necessary the allocation of costs associated with prosecution of Jointly Owned Intellectual Property or Newly Created Intellectual Property described under Section 10.2(b) that falls outside the foregoing.

17.4         Newly Created Intellectual Property.  As relates to Newly Created Intellectual Property: Eleos shall have the right to file patent applications at its own expense in any country or countries in which AVI has not elected to secure patent rights or in which AVI’s patent rights hereunder have terminated, and such applications and resultant patents shall not be subject to this Agreement and may be freely licensed by Eleos to third parties; and,  AVI shall have the right to file patent applications at its own expense in any country or countries in which Eleos has not elected to secure patent rights or in which Eleos’ patent rights hereunder have terminated, and such applications and resultant patents shall not be subject to this Agreement and may be freely licensed by AVI to third parties.

19.                                 Infringement.

19.1         In the event that a Party learns of the substantial infringement in the AVI Field, Eleos Field or Joint Field of any patent included in the other Party’s Intellectual Property licensed under this Agreement, the Party with such information shall notify the other Party in writing and shall provide the other Party with evidence of such infringement.  Both Parties agree that during the period and in a jurisdiction where a Party has exclusive rights under this Agreement under the other Party’s Intellectual

19

Property, neither will notify a third party of the infringement of any of such other Party’s Intellectual Property without first obtaining consent of the other Party, which consent shall not be unreasonably denied.  Both Parties shall use their best efforts to cooperate with each other to terminate such infringement without litigation.

19.2         A Party may request that the other Party take legal action against the infringement of the other Party’s Intellectual Property.  Such request shall be made in writing and shall include reasonable evidence of such infringement.  If the infringing activity has not been abated within ninety (90) days following the effective date of such request, the first Party shall have the right to commence suit on its own account or to refuse to commence such suit.

19.3         Each Party agrees to cooperate with the other in litigation proceedings instituted hereunder but at the expense of the Party on account of whom suit is brought for out-of-pocket expenses.  Such litigation shall be controlled by the Party bringing the suit.  Each Party may be represented by counsel of its choice at its own expense.  If a Party selects its own counsel in the conduct of such a suit, its counsel shall keep the other Party informed of the progress and status of such suit.

20.                                 Indemnification and Insurance.

20.1         Indemnification.  To the maximum extent permitted by law, each Party (the “Indemnifying Party”) shall indemnify, hold harmless and defend the other Party (the “Indemnified Party”), its shareholders, directors, officers, employees, agents and inventors against any and all claims, suits, losses, liabilities, damages, costs, fees and expenses (including reasonable attorneys’ fees) resulting from or arising out of any claim brought by a third party against the Indemnified Party related to any actual or alleged (a) breach of a representation or warranty by the Indemnifying Party under this Agreement; (b) product liability claim which is related to or arises out of the manufacture, marketing, distribution, sale or use of Licensed Products by the Indemnifying Party, except to the extent attributable to the Indemnified Party’s breach of its representations and warranties provided in this Agreement; (c) willful misconduct or gross negligence of the Indemnifying Party; or (d) breach of Section 27 (Confidentiality) by the Indemnifying Party.

20.2         Insurance.  Throughout the term of this Agreement, and to the extent applicable from and after the date of any use or sale of a Licensed Product, each Party shall maintain commercially issued policies of insurance or, with the prior written approval of the other Party, programs of self-insurance with financial reserves sufficient to support its obligations under this Agreement, which provide coverage and limits as required by statute or as necessary to prudently insure the activities and operations of the insuring Party.  The commercial general liability insurance policy, or liability self-insurance program, shall include the interests of the other Party as an additional insured and provide coverage limits of not less than $***** combined single limits as respects premises, operations, contractual liability and, if applicable, liability arising out of products and/or completed operations.  Each Party shall provide the other Party with certificates of insurance for commercially insured policies or evidence of self-insurance resources satisfactory to the other Party’s risk management department.  It is expressly agreed that the insurance or self-insurance are minimum requirements which shall not in any way limit the liability of a Party.

20.3         Procedures.  If an Indemnified Party seeks indemnification under this Section 20, it shall give prompt written notice to the Indemnifying Party of any claim covered by the foregoing duty of indemnification; provided, however, that a delay in such notice shall not terminate the duty of indemnification hereunder, unless such delay shall have materially impaired the defense of such claim.  The Indemnifying Party shall have sole and exclusive control of the defense of any such claim, including the choice and direction of any legal counsel.  In the event and for so long as a Party is actively contesting

20

or defending against any claim in connection with this Section 20, the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in the contest or defense, make itself available, and provide such testimony and access to its books and records as shall be reasonably necessary in connection with the contest or defense, all at the sole cost and expense of the Indemnifying Party.

21.                                 Notices.

Any notice or payment required to be given to either Party shall be deemed to have been properly given and to be effective (a) on the date of delivery if delivered in person, (b) five (5) days after mailing if mailed by first-class certified mail, postage paid and deposited in the United States mail, to the respective addresses given below, or to such other address as it shall designate by written notice given to the other Party, (c) on the date of delivery if delivered by express delivery service such as Federal Express or DHL or (d) on the date of transmission if made by facsimile.

22.                                 Assignment.

This Agreement shall be binding upon, and shall inure to the benefit of, the Parties and their respective Affiliates, successors and assigns.  No Party may assign any of its rights or privileges or delegate any of its duties or obligations (by operation of law or otherwise) hereunder without prior written consent of the other Party; provided, however, that either Party may make such an assignment or delegation in conjunction with (i) the acquisition of the Party or of all or substantially all of the Party’s assets relating to this Agreement other than, in the case of Eleos, any of the foregoing involving Genta Incorporated, Idera Pharmaceuticals, Inc. (formerly Hybridon, Inc.), ISIS Pharmaceuticals, Inc. or any of their affiliates or (ii) a corporate restructuring or reorganization in which such Party assigns its right, title and interest under this Agreement to an Affiliate.  Any attempted or purported assignment or transfer without such consent, when required under this provision, shall be void and of no effect and shall constitute a material breach of this Agreement.

23.                                 Late Payments.

In the event any amounts due a Party hereunder, including but not limited to royalty payments, milestone payments, fees and patent cost reimbursements, are not received when due except when prevented by force majeure, the paying Party shall pay to the other Party interest charges at a rate of twelve (12) percent per annum or the highest rate permitted by law if less than 12%.  Such interest shall be calculated from the date payment was due until actually received.

21

24.                                 Waiver.

It is agreed that failure to enforce any provisions of this Agreement by a Party shall not be deemed a waiver of any breach or default hereunder by the other Party.  It is further agreed that no express waiver by either Party hereto of any breach or default of any of the covenants or agreements herein set forth shall be deemed a waiver as to any subsequent and/or similar breach or default.

25.                                 Governing Law.

27.1         Nondisclosure and Non-Use.  Each Party shall keep all Confidential Information of the other Party supplied to or learned by it in the strictest confidence and shall not disclose such Confidential Information to an unauthorized party.  Each Party shall take proper and appropriate steps to protect such Confidential Information received or learned by it and its personnel, and shall use no less than a reasonable standard of care to protect such Confidential Information.  Each Party shall limit disclosure and access to such Confidential Information to only those of its personnel who are directly involved with the Party’s activities under this Agreement.  Each Party shall ensure that its personnel performing services under this Agreement or any Statement of Work or having access to Confidential Information of the other Party shall preserve the confidential nature of such Confidential Information, and shall be primarily liable for any breaches of the obligations of this Section 27 by its personnel.  Each Party will use all Confidential Information of the other Party only in connection with the performance of the activities contemplated by this Agreement.

27.2         Exceptions.  This Section 27 shall not apply to any information that (a) is already known by the recipient at the time of its disclosure to the recipient; (b) is publicly available or later becomes publicly available through no unauthorized or wrongful act; or (c) is disclosed to the recipient by a third party having no similar confidentiality obligation.

27.3         Compelled Disclosure.  If a Party is required by law or court order to disclose Confidential Information of the other Party, it shall provide the other Party with prompt written notice of such requirement so that an appropriate protective order or other relief may be sought.

27.4         Third-Party Information.  If any Confidential Information is supplied to a Party by a third party having a legal right to disclose it, then: (a) the receiving Party shall have the right to use that portion of the Confidential Information so disclosed only in connection with work done for that third party; and (b) such disclosure by that third party shall not place that portion of the Confidential Information in the public domain, and shall not relieve the receiving Party of its obligations under this Agreement.

22

27.5         Binding on Personnel.  Each Party shall provide to each of its personnel performing services under this Agreement notice of the confidentiality and non-use restrictions contained in this Agreement prior to allowing such personnel to receive any Confidential Information from the other Party or perform any services hereunder.

27.6         Equitable Relief.  Each Party acknowledges that a breach of this Section 27 would cause irreparable harm and injury to the other Party, which harm and injury could not be adequately compensated for by damages.  Accordingly, in the event of such a breach, the Parties agree that each of them shall be entitled, in its discretion and without posting a bond, to immediate injunctive relief in addition to any other remedies it might have, whether at law or in equity.

27.7         Survival.  The obligations imposed by this Section 27 shall survive with respect to each item of Confidential Information so long as no circumstance described in Section 27.2 has occurred.

28.                                 Dispute Resolution.

28.1         General.  Any dispute arising out of or relating to this Agreement shall be resolved in accordance with the procedures specified in this Section 28, which shall be the sole and exclusive procedures for the resolution of any such disputes.

28.2         Negotiation.  The Parties shall attempt in good faith to resolve any dispute arising out of or relating to this Agreement promptly by negotiation between executives who have authority to settle the controversy and who are at a higher level of management than the persons with direct responsibility for administration of this Agreement.  A Party may give the other Party written notice of any dispute not resolved in the normal course of business.  Within 15 days after delivery of the notice, the receiving Party shall submit to the other a written response.  The notice and response shall include (a) a statement of that Party’s position and a summary of arguments supporting that position, and (b) the name and title of the executive who will represent that Party and of any other person who will accompany the executive.  Within 30 days after delivery of the initial notice, the executives of both Parties shall meet at a mutually acceptable time and place, and thereafter as often as they reasonably deem necessary, to attempt to resolve the dispute.  All negotiations pursuant to this Section 28.2 are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

28.3         Arbitration.  If the dispute has not been resolved by negotiation as provided herein within 45 days after delivery of the initial notice of negotiation, or if the Parties failed to meet within 30 days after such delivery, the dispute shall be finally resolved by binding arbitration before three arbitrators in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”) then pertaining.  The three arbitrators shall be appointed by the AAA and shall each be neutral, independent, disinterested, impartial and shall abide by the Code of Ethics for Arbitrators in Commercial Disputes approved by the AAA.  The parties hereby consent to the jurisdiction of the federal district court for the district in which the arbitration is held for the enforcement of this provision and the entry of judgment on any award rendered hereunder.  Should such court for any reason lack jurisdiction, any court with jurisdiction shall enforce this clause and enter judgment on any award.  The place of arbitration will be Denver, Colorado or such other neutral site as the parties may jointly select.

28.4         Injunctive Relief.  Notwithstanding the provisions of this Section 28, each Party shall be entitled to seek injunctive relief at any time in any court of competent jurisdiction.

23

29.                                 Force Majeure.

No Party shall be deemed to be in breach of this Agreement or otherwise be liable to the other Party by reason of any delay in performing or failure to perform any obligations hereunder to the extent that such delay or failure was due to any event of force majeure of which it has notified the other Party, and the time of performance of that obligation shall be extended accordingly.  If the event of force majeure prevails for a continuous period in excess of three months, the Parties shall enter into bona fide discussions with a view to alleviating its effects or to agree to such alternative arrangements as may be fair and reasonable.  Without prejudice to the generality of the foregoing, the following without limitation shall be regarded as events of force majeure: acts of God; explosions; floods; tempest; fires or accidents; war or threat of war; acts, restrictions or regulations of any government or governmental agency; import or export regulations or embargoes; strikes or other labor troubles not limited to the labor force of the affected Party; difficulties in obtaining raw materials; power failure or breakdowns in machinery or any other cause beyond the control of, or occurring without the fault of, the Party asserting the event of force majeure.

30.6         Publications.  The Parties will be entitled to publish or present on the results of the research hereunder and any Product, provided that the Party seeking to publish will deliver to the other Party for its review a copy of any proposed publication, poster or an abstract of any oral presentation at scientific meetings involving any research or Product hereunder, or the Confidential Information of the other Party, at least forty-five (45) days prior to submission of scientific publications or abstracts of oral presentations.  The reviewing Party will have the right to request that any of its Confidential Information
