If the Parties jointly determine that the continuous subcutaneous administration of Angiozyme(TM) using the System is commercially viable, then the Parties shall in good faith negotiate a nonexclusive license to Newco of the Elan Intellectual Property and of the RPI Intellectual Property to make, have made, import, use, offer for sale and sell such product, subject to then existing contractual obligations. Such license agreement shall contain normal commercial terms, provided that (i) the research, development and commercialization of such product shall be without any cost or obligation whatsoever to Elan without Elan's prior written consent which may be withheld in Elan's sole discretion, and (ii) [ * ] Notwithstanding anything contained in this Clauses 7.2 to the contrary, Newco shall not have the license or right to manufacture or have manufactured the System with respect to the Product or to manufacture or have manufactured Angiozyme(TM) with respect to the product described in this Clause 7.2.

Any such inspection of Elan's or RPI's records, as the case may be, shall be at the expense of Newco, except that if such inspection reveals an overpayment in the amount paid to Elan or RPI, as the case may be, for the Research and Development Program hereunder in any Financial Year of [ * ] or more of the amount due to Elan or RPI, as the case may be, then the expense of such inspection shall be borne solely by Elan or RPI, as the case may be, instead of by Newco. Any surplus over the sum properly payable by Newco to Elan or RPI, as the case may be, shall be paid promptly by Elan or RPI, as the case may be, to Newco. If such inspection reveals a deficit in the amount of the sum properly payable to Elan or RPI, as the case may be, by Newco, Newco shall pay the deficit to Elan or RPI, as the case may be.

If Elan elects to enter into such negotiations, the Parties shall negotiate in good faith the terms of an applicable agreement. If, despite good faith negotiations, Elan and Newco do not reach agreement within [ * ] from [ * ], then Newco shall be free to enter into negotiations and an agreement with a third party (other than a Technological Competitor of Elan) upon which the third party would commercialize the relevant Product in the Territory, which terms when taken as a whole, are not more favourable to the third party than the principal terms of the last written proposal offered by Newco to Elan or by Elan to Newco, as the case may be. The Parties shall act in good faith and use their reasonable commercial judgement when negotiating with such third party for the commercialization of the Product in the Territory. For purposes of this Clause 8.2, the term Elan shall include Elan and its Affiliates. 21 CLAUSE 9 SUBLICENSE AND ASSIGNMENT RIGHTS 9.1 Newco shall be permitted to assign or sublicense the Newco Intellectual Property and to enter into agreements with third parties for the development of the Newco Intellectual Property upon unanimous approval by the Management Committee. 9.2 Upon 30 days prior notice in writing from Elan to Newco and RPI, Newco shall assign the Newco Intellectual Property from Newco to a wholly- owned subsidiary of Newco to be incorporated in Ireland, which company shall be newly incorporated by Elan to facilitate such assignment. 9.3 The Parties acknowledge and agree to be bound by the provisions of Clause 2.6 of the Elan License Agreement and the provisions of Clause 2.6 of the RPI License Agreement which set forth the agreement between the Parties thereto in relation to the assignment and sub-licensing of the Elan Intellectual Property and the RPI Intellectual Property respectively.

Upon such written request from Newco, Elan shall be responsible for preparing and prosecuting and otherwise seeking patent protection for such Elan Intellectual Property described in this Clause 11.3. Any such Elan Intellectual Property shall be owned by Elan but Elan shall grant to Newco a royalty free exclusive license to such Elan Intellectual Property in the Field. The Parties shall have the right to remove their confidential information from any such patent application. 11.4 In the event that RPI does not intend to file for patent protection on patentable inventions or discoveries within the RPI Intellectual Property that relates to the Field in one or more countries in the Territory after providing written notice to Newco and Elan, Newco shall have the option at Newco's expense, upon the prior written approval of RPI which approval shall not be unreasonably withheld, to request RPI to file and prosecute such patent application(s) jointly on behalf of Newco and Elan.

The Parties shall have the right to remove their confidential information from any such patent application. 11.6 In the event that Newco informs both Elan and RPI that it does not intend to file an application on the Newco Intellectual Property in or outside the Field, Elan shall have the right to file and prosecute such patent applications on inventions that Elan invents solely or which relate predominantly to the Elan Intellectual Property, and RPI shall have the right to file and prosecute such patent applications on inventions which RPI invents solely or which relate predominantly to the RPI Intellectual Property, and Elan and RPI agree to negotiate in good faith on the course of action to be taken with respect to Newco inventions that relate to both the Elan and RPI Intellectual Property. The Parties shall have the right to remove their confidential information from any such patent application. 11.7 The Parties shall promptly inform each other in writing of any actual or alleged unauthorized use of any Elan Intellectual Property, the RPI Intellectual Property or the Newco Intellectual Property by a third party of which it becomes aware and provide the others with any available evidence of such unauthorized use. 11.8 At its option, as the case may be, Elan or RPI shall have the first option to enforce at its own expense and for its own benefit any unauthorized use of its respective Intellectual Property (the Elan Intellectual Property or the RPI Intellectual Property as the case may be) in the Field. At the enforcing party's request, the other Parties shall cooperate with such action. Should Elan or RPI decide not to enforce the Elan Intellectual Property or the RPI Intellectual Property respectively, against such unauthorized use in the Field, within a reasonable period but in any event within twenty (20) days after receiving written notice of such actual or alleged unauthorized use, Newco may in its discretion initiate such proceedings in its own name, at its expense and for its own benefit, and at such Party's request, Elan and RPI shall cooperate with such action. Any recovery remaining after the deduction by Newco of the reasonable expenses (including attorney's fees and expenses) incurred in relation to such enforcement proceeding shall belong to Newco. Alternatively, the Parties may agree to institute such proceedings in their joint names and shall reach agreement as to the proportion in which they shall share the proceeds of any such proceedings, and the expense of any costs not recovered, or the costs or damages payable to the third party. If the infringement of the Elan Patents or the RPI Patents affects both the Field as well as other products being developed or commercialized by RPI or Elan or its commercial partners outside the Field, RPI or Elan shall endeavor to agree as to the manner in which the proceedings should be instituted and as to the proportion in which they shall share the proceeds of any such proceedings, 24 and the expense of any costs not recovered, or the costs or damages payable to the third party. 11.9 Newco shall have the first right but not the obligation to bring suit or otherwise take action against any unauthorized use of the Newco Intellectual Property. If any such alleged use occurs that gives rise to a cause of action both inside and outside the Field, Newco, in consultation with the other Parties, shall determine the course of action to be taken. In the event that Newco takes such action, Newco shall do so at its own cost and expense and all damages and monetary award recovered in or with respect to such action shall be the property of Newco. Newco shall keep Elan and RPI informed of any action in a timely manner so as to enable RPI and Elan to provide input in any such action and Newco shall reasonably take into consideration any such input. At Newco's request, the Parties shall cooperate with any such action at Newco's cost and expense. 11.10 In the event that Newco does not bring suit or otherwise take action against any unauthorized use of the Newco Intellectual Property (i) if only one Party determines to pursue such suit or take such action at its own cost and expense, it shall be entitled to all damages and monetary award recovered in or with respect to such action and (ii) if the other Parties pursue such suit or action outside of Newco, they shall negotiate in good faith an appropriate allocation of costs, expenses and recovery amounts. At the Party's request, Newco shall cooperate with any such action at the Party's cost and expense. 11.11 In the event that a claim or proceeding is brought against Newco by a third party alleging that the sale, distribution or use of a Product in the Territory constitutes the unauthorized use of the intellectual property rights of such Party, Newco shall promptly advise the other Parties of such threat or suit. 11.12 Save in respect of claims by Newco against either Party, or by an Independent Third Party against Newco, where Elan is in breach of a representation or warranty under [ * ] or where RPI is in breach of a representation or warranty under [ * ] shall indemnify, defend and hold harmless Elan or RPI, as the case may be, against all actions, losses, claims, demands, damages, costs and liabilities (including reasonable attorneys fees) relating directly or indirectly to all such claims or proceedings referred to in [ * ], provided that Elan or RPI, as the case may be, shall not acknowledge to the third party or to any other person the validity of any claims of such a third party, and shall not compromise or settle any claim or proceedings relating thereto without the prior written consent to Newco, not to be unreasonably withheld or delayed. At its option, Elan or RPI, as the case may be, may elect to take over the conduct of such proceedings from Newco provided that Newco's indemnification obligations shall continue; the costs of defending such claim shall be borne by Elan or RPI, as the case may be and such Party shall not compromise or settle any such claim or proceeding without the prior written consent of Newco, such consent not to be unreasonably withheld or delayed. 25 CLAUSE 12 CROSS LICENSING/EXPLOITATION OF PRODUCTS OUTSIDE THE FIELD 12.1 Solely for the purpose of and insofar as is necessary, in each case, for Elan to perform research and development work on behalf of Newco, Newco shall grant to Elan a non-exclusive, worldwide, royalty-free, fully paid-up license for the term of the Licenses: 12.1.1 to use the Newco Intellectual Property in the Field, and 12.1.2 subject to the terms and conditions of the RPI License, a sublicense to use the RPI Intellectual Property in the Field. 12.2 Solely for the purpose of and insofar as is necessary, in each case, for RPI to conduct research and development work on behalf of Newco, Newco shall grant to RPI a non-exclusive, worldwide, royalty-free, fully paid-up license for the term of the Licenses: 12.2.1 to use the Newco Intellectual Property in the Field, and 12.2.2 subject to the terms and conditions of the Elan License and the Elan Research License, a sublicense to use the Elan Intellectual Property in the Field. 12.3 Subject to the provisions of this Clause 12, Newco hereby grants to each of Elan and RPI a license to the Newco Intellectual Property as follows: 12.3.1 Newco hereby grants to Elan a worldwide, perpetual, fully- paid and royalty-free license, with the right to sublicense, to the Newco Intellectual Property as it relates to the System for use outside the Field on an as-is basis without recourse, representation or warranty whether express or implied, including warranties of merchantability or fitness for a particular purpose, or infringement of third party rights, and all such warranties are expressly disclaimed. 12.3.2 Newco hereby grants to RPI a worldwide, perpetual, fully- paid and royalty-free license, with the right to sublicense, to the Newco Intellectual Property as it relates to the Target Ribozyme for use outside the Field on an as-is basis without recourse, representation or warranty whether express or implied, including warranties of merchantability or fitness for a particular purpose, or infringement of third party rights, and all such warranties are expressly disclaimed.

All regulatory approvals and submissions relating to the Target Ribozyme, including without limitation, the DMF, shall be processed by and be the property of RPI and at all times held in RPI's sole name. All regulatory approvals and submissions relating to the System, including without limitation, the MAF, shall be processed by and be the property of Elan and at all times held in Elan's sole name.

Until such time as the Common Shares shall be registered pursuant to the Exchange Act and be publicly traded in an established securities market, no Shareholder shall, directly or indirectly, sell or otherwise transfer (each, a "Transfer") any Shares held by it except in as expressly permitted by and in accordance with the terms of this Agreement. Newco shall not, and shall not permit any transfer agent or registrar for any Shares to, transfer upon the books of Newco any Shares from any Shareholder to any transferee, in any manner, except in accordance with this Agreement, and any purported transfer not in compliance with this Agreement shall be void. During the Research and Development Term, no Shareholder shall, directly or indirectly, sell or otherwise Transfer any of its legal and/or beneficial interest in the Shares held by it to any other Person. After completion of the Research and Development Term, a 29 Shareholder may Transfer Shares provided such Shareholder complies with the provisions of Clauses 17.2 and 17.3. Notwithstanding anything contained herein to the contrary, at all times, EIS and/or RPI shall have the right to Transfer any Shares to their Affiliates provided, however, that such assignment does not result in adverse tax consequences for any other Parties. EIS shall have the right to Transfer any Shares to a special purpose financing or similar entity established by Elan or EIS; provided, that such Affiliates or other Permitted Transferee to which such legal and/or beneficial interest in the Shares have been transferred shall agree to be expressly subject to and bound by all the limitations and provisions which are embodied in this Agreement. 17.2 No Shareholder shall, except with the prior written consent of the other Shareholder, create or permit to subsist any Encumbrance over or in, all or any of the Shares held by it (other than by a Transfer of such Shares in accordance with the provisions of this Agreement). 17.3 Rights of First Offer: ---------------------- If at any time after the end of the Research and Development Term a Shareholder shall desire to Transfer any Shares owned by it (a "Selling Shareholder"), in any transaction or series of related transactions other than a Transfer to an Affiliate or subsidiary or in the case of EIS to a special purpose financing or similar entity established by EIS, then such Selling Shareholder shall deliver prior written notice of its desire to Transfer (a "Notice of Intention") (i) to Newco and (ii) to the Shareholders who are not the Selling Shareholder (and any transferee thereof permitted hereunder, if any), as applicable, setting forth such Selling Shareholder's desire to make such Transfer, the number of Shares proposed to be transferred (the "Offered Shares") and the proposed form of transaction (the "Transaction Proposal"), together with any available documentation relating thereto, if any, and the price at which such Selling Shareholder proposes to Transfer the Offered Shares (the "Offer Price"). The "Right of First Offer" provided for in this Clause 17 shall be subject to any "Tag Along Right" benefiting a Shareholder which may be provided for by Clause 17, subject to the exceptions set forth therein. Upon receipt of the Notice of Intention, the Shareholders who are not the Selling Shareholder shall have the right to purchase at the Offer Price the Offered Shares, exercisable by the delivery of notice to the Selling Shareholder (the "Notice of Exercise"), with a copy to Newco, within 10 business days from the date of receipt of the Notice of Intention. If no such Notice of Exercise has been delivered by the Shareholders who are not the Selling Shareholder within such 10-business day period, or such Notice of Exercise does not relate to all of the Offered Shares covered by the Notice of Intention, then the Selling Shareholder shall be entitled to Transfer all of the Offered Shares to the intended transferee. In the event that all of the Offered Shares are not purchased by the non-selling Shareholders, the Selling Shareholder shall sell the available Offered Shares within 30 days after the delivery of such Notice of Intention on terms no more favorable to a third party than those presented to the non- selling Shareholders. If such sale does not 30 occur, the Offered Shares shall again be subject to the Right of First Refusal set forth in Clause 17.3. In the event that any of the Shareholders who are not the Selling Shareholder exercises their right to purchase all of the Offered Shares (in accordance with this Clause 17), then the Selling Shareholder shall sell all of the Offered Shares to such Shareholder(s), in the amounts set forth in the Notice of Intention, after not less than 10 business days and not more than 25 business days from the date of the delivery of the Notice of Exercise. In the event that more than one of the Shareholders who are not the Selling Shareholders wish to purchase the Offered Shares, the Offered Shares shall be allocated to such Shareholders on the basis of their pro rata equity interests in Newco. The rights and obligations of each of the Shareholders pursuant to the Right of First Offer provided herein shall terminate upon the date that the Common Shares are registered under Section 12(b) or 12(g) of the Exchange Act. At the closing of the purchase of all of the Offered Shares by the Shareholders who are not the Selling Shareholder (scheduled in accordance with Clause 17), the Selling Shareholder shall deliver certificates evidencing the Offered Shares being sold, duly endorsed, or accompanied by written instruments of transfer in form reasonably satisfactory to the Shareholders who are not the Selling Shareholder, duly executed by the Selling Shareholder, free and clear of any adverse claims, against payment of the purchase price therefor in cash, and such other customary documents as shall be necessary in connection therewith. 17.4 Tag Along Rights: ----------------- Subject to Clause 17.3, a Shareholder (the "Transferring Shareholder") shall not Transfer (either directly or indirectly), in any one transaction or series of related transactions, to any Person or group of Persons, any Shares, unless the terms and conditions of such Transfer shall include an offer to the other Shareholders (the "Remaining Shareholders"), to sell Shares at the same price and on the same terms and conditions as the Transferring Shareholder has agreed to sell its Shares (the "Tag Along Right"). In the event a Transferring Shareholder proposes to Transfer any Shares in a transaction subject to this Clause 17.4, it shall notify, or cause to be notified, the Remaining Shareholders in writing of each such proposed Transfer. Such notice shall set forth: (i) the name of the transferee and the amount of Shares proposed to be transferred, (ii) the proposed amount and form of consideration and terms and conditions of payment offered by the transferee (the "Transferee Terms") and (iii) that the transferee has been informed of the Tag Along Right provided for in this Clause 17, if such right is applicable, and the total number of Shares the transferee has agreed to purchase from the Shareholders in accordance with the terms hereof. 31 The Tag Along Right may be exercised by each of the Remaining Shareholders by delivery of a written notice to the Transferring Shareholder (the "Co- sale Notice") within 10 business days following receipt of the notice specified in the preceding subsection. The Co-sale Notice shall state the number of Shares owned by such Remaining Shareholder which the Remaining Shareholder wishes to include in such Transfer; provided, however, that without the written consent of the Transferring Shareholder, the amount of such securities belonging to the Remaining Shareholder included in such Transfer may not be greater than such Remaining Shareholder's percentage beneficial ownership of Fully Diluted Common Shares multiplied by the total number of shares of 7 Diluted Common Shares to be sold by both the Transferring Shareholder and all Remaining Shareholders. Upon receipt of a Co-sale Notice, the Transferring Shareholder shall be obligated to transfer at least the entire number of Shares set forth in the Co-sale Notice to the transferee on the Transferee Terms; provided, however, that the Transferring Shareholder shall not consummate the purchase and sale of any Shares hereunder if the transferee does not purchase all such Shares specified in all Co-sale Notices. If no Co-sale Notice has been delivered to the Transferring Shareholder prior to the expiration of the 10 business day period referred to above and if the provisions of this Section have been complied with in all respects, the Transferring Shareholder shall have the right for a 45 day calendar day period to Transfer Shares to the transferee on the Transferee Terms without further notice to any other party, but after such 45-day period, no such Transfer may be made without again giving notice to the Remaining Shareholders of the proposed Transfer and complying with the requirements of this Clause 17. At the closing of any Transfer of Shares subject to this Clause 17, the Transferring Shareholder, and the Remaining Shareholder, in the event such Tag Along Right is exercised, shall deliver certificates evidencing such securities as have been Transferred by each, duly endorsed, or accompanied by written instruments of transfer in form reasonably satisfactory to the transferee, free and clear of any adverse claim, against payment of the purchase price therefor. Notwithstanding the foregoing, this Clause 17 shall not apply to any sale of Common Shares pursuant to an effective registration statement under the Securities Act in a bona fide public offering.

CLAUSE 19 DISPUTES 19.1 During the Term of this Agreement, should any dispute or difference arise amongst the members of the Management Committee, or between Elan and RPI, or between Elan or RPI and Newco, the appropriate representatives of the applicable Parties shall use good faith efforts to resolve such dispute or difference promptly and to the mutual satisfaction of the affected Parties. If with respect to any such dispute or difference (but excluding from the remaining provisions of this Clause 19 any dispute or difference relating to (i) the interpretation of any provision of this Agreement, (ii) the interpretation or application of law, or (iii) the ownership of any intellectual property, which disputes or differences shall be resolved, if at all, by arbitration pursuant to Clause 24.8), such representatives cannot reach a resolution to such dispute or difference within a reasonable period, then any Party may forthwith give notice to the other Parties that it wishes such dispute or difference to be referred to the chief executive officer of RPI and the President of Elan Pharmaceutical Technologies. 19.2 In any event of a notice being served in accordance with Clause 19.1, each of the Participants shall within 14 days of the service of such notice prepare and circulate to the chief executive officer of each Participant a memorandum or other form of statement setting out its position on the matter in dispute and its reasons for adopting that position. Each memorandum or statement shall be considered by the chief executive officers of the Participants who shall endeavor using good faith diligent efforts to resolve the dispute. If the chief executive officers of the Participants agree upon a resolution or disposition of the matter, they shall each sign a statement which sets out the terms of their agreement. The Participants agree that they shall exercise the voting rights and other powers available to them in relation to Newco to procure that the agreed terms are fully and promptly carried into effect. 19.3 The chief executive officer of RPI and the President of Elan Pharmaceutical Technologies shall, if they are unable to resolve a dispute or difference when it is referred to them under Clause 19.1, within sixty (60) days of such referral, refer the matter to an independent expert in pharmaceutical product development and marketing (including clinical development and regulatory affairs) jointly selected by the chief executive officers of the Participants (the "Expert"). In the event the chief executive officers of the Participants cannot agree upon the designation of the Expert, the Participants shall request the American Arbitration Association ("AAA"), sitting in the City of New York to select the Expert. In each case, the Expert shall be selected having regard to his suitability to determine the particular dispute or difference on which the Expert is being requested to determine. Unless otherwise agreed between the chief executive officers, 34 the following rules shall apply to the appointment of the Expert. The fees of the AAA and the Expert shall be shared equally by the Participants. The Expert shall be entitled to inspect and examine all documentation and any other material which the Expert may consider to be relevant to the dispute. The Expert shall afford each Party a reasonable opportunity (in writing or orally) of stating reasons in support of such contentions as each Party may wish to make relative to the matters under consideration. The Expert shall give notice in writing of his determination to the Parties within such time as may be stipulated in his terms of appointment or in the absence of such stipulation as soon as practicable but in any event within four weeks from the reference of the dispute or difference to him. 19.4 Any determination by the Expert of a dispute or difference shall not be binding on the Parties. CLAUSE 20 TERMINATION 20.1 This Agreement shall govern the operation and existence of Newco until (i) terminated by written agreement of all Parties hereto or (ii) otherwise terminated in accordance with this Clause 20. 20.2 For the purpose of this Clause 20, a "Relevant Event" is committed or suffered by a Participant if: 20.2.1 it commits a breach of its material obligations under this Agreement or the applicable License and fails to remedy it within 60 days of being specifically required in writing to do so by the other Participant; provided, however, that if the breaching Participant has proposed a course of action to rectify the breach and is acting in good faith to rectify same but has not cured the breach by the 60th day, such period shall be extended by such period as is reasonably necessary to permit the breach to be rectified; or 20.2.2 a distress, execution, sequestration or other process is levied or enforced upon or sued out against a material part of its property which is not discharged or challenged within 30 days; or 20.2.3 it is unable to pay its debts in the normal course of business; or 20.2.4 it ceases wholly or substantially to carry on its business, otherwise than for the purpose of a reconstruction or amalgamation, without the prior written consent of the other Participant (such consent not to be unreasonably withheld); or 20.2.5 the appointment of a liquidator, receiver, administrator, examiner, trustee or similar officer of such Participant or over all or substantially all of its assets under 35 the law of any applicable jurisdiction, including without limitation, the United States of America, Bermuda or Ireland; or 20.2.6 an application or petition for bankruptcy, corporate re- organization, composition, administration, examination, arrangement or any other procedure similar to any of the foregoing under the law of any applicable jurisdiction, including without limitation, the United States of America, Bermuda or Ireland, is filed, and is not discharged within 60 days, or a Participant applies for or consents to the appointment of a receiver, administrator, examiner or similar officer of it or of all or a material part of its assets, rights or revenues or the assets and/or the business of a Participant are for any reason seized, confiscated or condemned. 20.4 If either Participant commits or suffers a Relevant Event, the other Participant shall be entitled, within three months of the occurrence of the Relevant Event, to require the defaulting Participant (the "Recipient Participant") to sell on reasonable terms of payment to the non-defaulting Participant (the "Proposing Participant") all (but not some only) of the Shares, held or beneficially owned by the Recipient Participant for an amount equal to [*] of the fair market value of the Shares of the Recipient Participant (the "Buyout Option"). 20.5 The Proposing Participant shall notify the Recipient Participant of the exercise of the Buyout Option, no later than 30 business days prior to the proposed exercise thereof, by delivering written notice to the Recipient Participant stating that the Buyout Option is exercised and the price at which the Proposing Participant is willing to purchase the Shares of the Recipient Participant. 20.6 In the event that the Participants do not agree upon a purchase price for the Shares within five Business Days following the receipt by the Recipient Participant of written notice from the Proposing Participant pursuant to Clause 20.5 above, the Proposing Participant may contact the AAA, sitting in New York City and request that an independent US-based arbitrator who is knowledgeable of the pharmaceutical/biotechnology industry be appointed within 10 Business Days. The AAA shall endeavor to select an arbitrator who is technically knowledgeable in the pharmaceutical/biotechnology industry (and who directly and through his affiliates, has no business relationship with, or shareholding in, either the Proposing Participant or the Recipient Participant). Promptly upon being notified of the arbitrator's appointment, the Proposing Participant and the Recipient Participant shall submit to the arbitrator details of their assessment of the fair market value for the Shares of the Recipient Participant together with such information as they think necessary to validate their assessment. The arbitrator shall notify the Recipient Participant of [*] of the fair market value assessed by the Proposing Participant (the "Proposing Participant Price") and shall notify the Proposing Participant of [*] of the fair market value assessed by the Recipient Participant (the "Recipient Participant Price"). The Proposing Participant and the Recipient Participant shall then be entitled to make further submissions to the arbitrator within five Business Days explaining why the Recipient Participant Price or the Proposing Participant Price, as the case may be, is unjustified. The arbitrator shall thereafter meet with the Proposing Participant and the 36 Recipient Participant and shall thereafter choose either the Recipient Participant Price or the Proposing Participant Price (but not any other price) as the purchase price for the Shares (the "Purchase Price") on the basis of which price the Expert determines to be closer to [*] of the fair market value for the Shares of the Recipient Participant. The arbitrator shall use his best efforts to determine the Purchase Price within 30 Business Days of his appointment. The Proposing Participant and the Recipient Participant shall bear the costs of the arbitrator equally provided that the arbitrator may, in his discretion, allocate all or a portion of such costs to one Party. Any decision of the arbitrator shall be final and binding. 20.7 The Proposing Participant shall purchase the Shares of the Recipient Participant by delivery of the Purchase Price in cash no later than the 15th Business Day following determination of the Purchase Price by the Expert. 20.8 The Shares of the Recipient Participant so transferred shall be sold by the transferor as beneficial owner with effect from the date of such transfer free from any lien, charge or encumbrance with all rights and restrictions attaching thereto. If the Proposing Participant elects to purchase the Shares of the Recipient Participant, the Shares of the Recipient Participant shall be sold by the Recipient Participant as beneficial owner for a price equal to [*] of the Purchase Price with effect from the date specified by the Proposing Participant in its notice of election free from any lien, charge or encumbrance together with all rights attaching thereto. 20.9 If the Proposing Participant exercises the Buyout Option, both parties will negotiate in good faith to agree to additional reasonable provisions and/or amendments to the License Agreements to protect the intellectual property rights of the Recipient Party. 20.10 If either Participant commits a Relevant Event, the other Shareholder shall have in addition to all other legal and equitable rights and remedies hereunder, the right to terminate this Agreement upon 30 days' written notice. 20.11 In the event of a termination of the Elan License Agreement and/or the RPI License Agreement, both parties will negotiate in good faith to determine whether this Agreement should be terminated and if so, which provisions should survive termination. 20.12 The provisions of Clauses 1, 3, 5.1, 9, 10, 11, 12, 17, 20.12, 22, 23, and 24 shall survive the termination of this Agreement under this Clause 20.10 or by mutual consent pursuant to Clause 20.1 in accordance with their terms; all other terms and provisions of this Agreement shall cease to have effect and be null and void upon the termination of this Agreement under this Clause 20.10 or by mutual consent pursuant to Clause 20.1. 37 CLAUSE 21 SHARE RIGHTS 21.1 The Shareholders agree that the Common Shares and the Preferred Shares shall be separate classes of shares and shall carry the respective rights and be subject to the restrictions on the transfer and distribution of assets provided in the Newco Memorandum of Association and Bye-laws and as set forth in this Agreement. 21.2 Except as otherwise provided in the Bermuda Companies Act of 1981 and in the Newco Memorandum of Association and Bye-Laws, the Participants agree that for a period of two years from the Closing, the Preferred Shares issued to EIS shall not carry voting rights in Newco. CLAUSE 22 CONFIDENTIALITY 22.1 The Parties acknowledge and agree that it may be necessary, from time to time, to disclose to each other confidential and/or proprietary information, including without limitation, inventions, works of authorship, trade secrets, specifications, designs, data, know-how and other information, relating to the Field, the Products, present or future products, the Newco Intellectual Property, the Elan Intellectual Property or the RPI Intellectual Property, as the case may be, methods, compounds, research projects, work in process, services, sales suppliers, customers, employees and/or business of the disclosing Party, whether in oral, written, graphic or electronic form (collectively "Confidential Information"). 22.2 Any Confidential Information revealed by a Party to another Party shall be maintained as confidential and shall be used by the receiving Party exclusively for the purposes of fulfilling the receiving Party's rights and obligations under this Agreement and the License Agreements, and for no other purpose. Confidential Information shall not include: 22.2.1 information that is generally available to the public; 22.2.2 information that is made public by the disclosing Party; 22.2.3 information that is independently developed by the receiving Party, as evidenced by such Party's records, without the aid, application or use of the disclosing Party's Confidential Information; 22.2.4 information that is published or otherwise becomes part of the public domain without any disclosure by the receiving Party, or on the part of the receiving Party's directors, officers, agents, representatives or employees; 38 22.2.5 information that becomes available to the receiving Party on a non- confidential basis, whether directly or indirectly, from a source other than the disclosing Party, which source did not acquire this information on a confidential basis; or 22.2.6 information which the receiving Party is required to disclose pursuant to: (i) a valid order of a court or other governmental body or any political subdivision thereof or as otherwise required by law, rule or regulation; or (ii) other requirement of law; provided, however, that if the receiving Party becomes legally required to disclose any Confidential Information, the receiving Party shall give the disclosing Party prompt notice of such fact so that the disclosing Party may obtain a protective order or confidential treatment or other appropriate remedy concerning any such disclosure. The receiving Party shall fully co-operate with the disclosing Party in connection with the disclosing Party's efforts to obtain any such order or other remedy. If any such order or other remedy does not fully preclude disclosure, the receiving Party shall make such disclosure only to the extent that such disclosure is legally required; or 22.2.7 information which was already in the possession of the receiving Party at the time of receiving such information, as evidenced by its records, provided such information was not previously provided to the receiving party from a source which was under an obligation to keep such information confidential; or 22.2.8 information that is the subject of a written permission to disclose, without restriction or limitation, by the disclosing Party. 22.3 Each Party agrees to disclose Confidential Information of another Party only to those employees, representatives and agents requiring knowledge thereof in connection with their duties directly related to the fulfilling of the Party's obligations under this Agreement, so long as such persons are under an obligation of confidentiality no less stringent than as set forth herein. Each Party further agrees to inform all such employees, representatives and agents of the terms and provisions of this Agreement and their duties hereunder and to obtain their consent hereto as a condition of receiving Confidential Information. Each Party agrees that it will exercise the same degree of care and protection to preserve the proprietary and confidential nature of the Confidential Information disclosed by a Party, as the receiving Party would exercise to preserve its own Confidential Information. Each Party agrees that it will, upon request of another Party, return all documents and any copies thereof containing Confidential Information belonging to or disclosed by such other Party. Each Party shall promptly notify the other Parties upon discovery of any unauthorized use or disclosure of the other Parties' Confidential Information. 39 22.4 Notwithstanding the above, each Party may use or disclose Confidential Information disclosed to it by another Party to the extent such use or disclosure is reasonably necessary in filing or prosecuting patent applications, prosecuting or defending litigation, complying with patent applications, prosecuting or defending litigation, complying with applicable governmental regulations or otherwise submitting information to tax or other governmental authorities, conducting clinical trials, or granting a permitted sub-license or otherwise exercising its rights hereunder; provided, that if a Party is required to make any such disclosure of the other Party's Confidential Information, other than pursuant to a confidentiality agreement, such Party shall inform the third party recipient of the terms and provisions of this Agreement and their duties hereunder and shall obtain their consent hereto as a condition of releasing to the third party recipient the Confidential Information. 22.5 Any breach of this Clause 22 by any employee, representative or agent of a Party is considered a breach by the Party itself. 22.6 The provisions relating to confidentiality in this Clause 22 shall remain in effect during the Term and for a period of seven years following the termination of this Agreement. 22.7 The Parties agree that the obligations of this Clause 22 are necessary and reasonable in order to protect the Parties' respective businesses, and each Party expressly agrees that monetary damages would be inadequate to compensate a Party for any breach by the other Party of its covenants and agreements set forth herein. Accordingly, the Parties agree and acknowledge that any such violation or threatened violation will cause irreparable injury to a Party and that, in addition to any other remedies that may be available, in law or in equity or otherwise, any Party shall be entitled to obtain injunctive relief against the threatened breach of the provisions of this Clause 22, or a continuation of any such breach by the other Party, specific performance and other equitable relief to redress such breach together with its damages and reasonable counsel fees and expenses to enforce its rights hereunder, without the necessity of proving actual or express damages.
