The "Right of First Offer" provided for in this Clause 18 shall be subject to any "Tag Along Right" benefiting a Stockholder which may be provided for by Clause 18.3, subject to the exceptions set forth therein. Upon receipt of the Notice of Intention, the Stockholders who are not the Selling Stockholder shall have the right to purchase at the Offer Price the Offered Shares, exercisable by the delivery of notice to the Selling Stockholder (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 Stockholders who are not the Selling Stockholder within such 10-business day period, or such Notice of Exercise does not relate to all of the 29 33 Offered Shares covered by the Notice of Intention, then the Selling Stockholder 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 Stockholders, the Selling Stockholder 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 Stockholders.

In the event that more than one of the Stockholders who are not the Selling Stockholders wish to purchase the Offered Shares, the Offered Shares shall be allocated to such Stockholders on the basis of their pro rata equity interests in Newco. The rights and obligations of each of the Stockholders pursuant to the Right of First Offer provided herein shall terminate upon the date that the Common Stock is 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 Stockholders who are not the Selling Stockholder (scheduled in accordance with Clause 18.2), the Selling Stockholder shall deliver certificates evidencing the Offered Shares being sold, duly endorsed, or accompanied by written instruments of transfer in form reasonably satisfactory to the Stockholders who are not the Selling Stockholder, duly executed by the Selling Stockholder, 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. 18.3 TAG ALONG RIGHTS: Subject to Clause 18.2, a Stockholder (the "TRANSFERRING STOCKHOLDER") 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 Stockholders who have not exercised the Right of First Offer set forth above in Clause 18.2 (the "REMAINING STOCKHOLDERS"), to sell Shares at the same price and on the same terms and conditions as the Transferring Stockholder has agreed to sell its Shares (the "TAG ALONG RIGHT"). 30 34 In the event a Transferring Stockholder proposes to Transfer any Shares in a transaction subject to this Clause 18.3, it shall notify, or cause to be notified, the Remaining Stockholders 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 18.3, if such right is applicable, and the total number of Shares the transferee has agreed to purchase from the Stockholders in accordance with the terms hereof. The Tag Along Right may be exercised by each of the Remaining Stockholders by delivery of a written notice to the Transferring Stockholder (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 Stockholder which the Remaining Stockholder wishes to include in such Transfer; provided, however, that without the written consent of the Transferring Stockholder, the amount of such securities belonging to the Remaining Stockholder included in such Transfer may not be greater than such Remaining Stockholder's percentage beneficial ownership of Fully Diluted Common Stock multiplied by the total number of shares of Fully Diluted Common Stock to be sold by both the Transferring Stockholder and all Remaining Stockholders. Upon receipt of a Co-sale Notice, the Transferring Stockholder 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 Stockholder shall not consummate the purchase and sale of any Shares hereunder if the transferee does not agree to purchase all such Shares specified in all Co-sale Notices. If no Co-sale Notice has been delivered to the Transferring Stockholder 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 Stockholder 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 Stockholders of the proposed Transfer and complying with the requirements of this Clause 18.3. At the closing of any Transfer of Shares subject to this Clause 18.3, the Transferring Stockholder, and the Remaining Stockholder, in the event such Tag 31 35 [*****] INDICATES THAT CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND FILED SEPARATELY IN A REQUEST FOR CONFIDENTIAL TREATMENT WITH THE SECURITIES AND EXCHANGE COMMISSION.

Each memorandum or statement shall be considered by the chief executive officer of Celtrix and the President of EPT who shall endeavor to resolve the dispute. If the chief executive officer of Celtrix and the President of EPT 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 assure that the agreed terms are fully and promptly carried into effect. 20.3 The chief executive officer of Celtrix and the President of EPT shall, if they are unable to resolve a dispute or difference when it is referred to them under Clause 20.2, refer the matter to an independent expert in pharmaceutical product development and marketing (including clinical development and regulatory affairs) (the "EXPERT"). The Expert shall be selected by the presiding justice of the Supreme Court of the State of New York sitting in the County, City and State of New York (the "PRESIDING JUSTICE") or, if the Expert should have a conflict of interest, by such other Person as such justice shall select, having assured himself as to such Person's independence. 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 officer of Celtrix and the President of EPT, the following rules shall apply to the appointment of the Expert. The fees of the Expert shall be shared equally between the Parties in dispute. 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. 35 39 20.4 Any determination by the Expert of a dispute or difference shall not be final and binding on the Parties; provided, however, that any determination by the Expert of a dispute or difference referred by the Parties pursuant to Clause 21.6. shall be final and binding on the Parties. CLAUSE 21 TERMINATION 21.1 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 21. 21.2 For the purpose of this Clause 21, a "RELEVANT EVENT" is committed or suffered by a Participant if: 21.2.1 it commits a material breach of its 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; 21.2.2 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; 21.2.3 it is unable to pay its debts in the normal course of business; 21.2.4 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); 21.2.5 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 the law of any applicable jurisdiction, including without limitation, the United States of America, Bermuda or Ireland; 21.2.6 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 36 40 of its assets, rights or revenues or the assets and/or the business of a Participant are for any reason seized, confiscated or condemned. 21.4 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 the fair market value of the Shares of the Recipient Participant (the "BUYOUT OPTION"). 21.5 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. 21.6 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 21.5 above, the Proposing Participant may contact the Presiding Justice and request that an independent US-based arbitrator who is knowledgeable of the pharmaceutical/biotechnology industry be appointed within 10 Business Days. The Presiding Justice 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 the fair market value assessed by the Proposing Participant (the "PROPOSING PARTICIPANT PRICE") and shall notify the Proposing Participant 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 37 41 [*****] INDICATES THAT CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND FILED SEPARATELY IN A REQUEST FOR CONFIDENTIAL TREATMENT WITH THE SECURITIES AND EXCHANGE COMMISSION. Price or the Proposing Participant Price, as the case may be, is unjustified. The arbitrator shall thereafter meet with the Proposing Participant and the 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 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. 21.7 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. 21.8 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. 21.9 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. 21.10 If either Participant commits a Relevant Event, the other Stockholder 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. 21.11 In the event of a termination of the Elan License Agreement and/or the Celtrix 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. 21.12 The provisions of Clauses [*****] shall survive the termination of this Agreement under this Clause 21 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 21. 38 42 CLAUSE 22 [INTENTIONALLY OMITTED] CLAUSE 23 CONFIDENTIALITY 23.1 The Parties and/or Newco 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 Celtrix 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"). 23.2 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 for no other purpose.

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 23.2.7 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 23.2.8 information that is the subject of a written permission to disclose, without restriction or limitation, by the disclosing Party. 23.3 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 written 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 40 44 [*****] INDICATES THAT CONFIDENTIAL MATERIAL HAS BEEN OMITTED AND FILED SEPARATELY IN A REQUEST FOR CONFIDENTIAL TREATMENT WITH THE SECURITIES AND EXCHANGE COMMISSION. the other Parties upon discovery of any unauthorized use or disclosure of the other Parties' Confidential Information. 23.4 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. 23.5 Any breach of this Clause 23 by any employee, representative or agent of a Party is considered a breach by the Party itself. 23.6 The provisions relating to confidentiality in this Clause 23 shall remain in effect during the Term and for a period of [*****] following the termination of this Agreement. 23.7 The Parties agree that the obligations of this Clause 23 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 23, 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. 23.8 If it is necessary for Celtrix to file a copy of this Agreement with the Securities and Exchange Commission pursuant to applicable law, then (a) Celtrix shall consult with Elan, and keep Elan fully informed, with respect thereto, and (b) Celtrix shall use its best efforts to obtain confidential treatment to the maximum extent possible with respect to such filing of this Agreement. 41 45 CLAUSE 24 COSTS 24.1 Each Stockholder shall bear its own legal and other costs incurred in relation to preparing and concluding this Agreement and the Transaction Documents. 24.2 All other costs, legal fees, registration fees and other expenses relating to the transactions contemplated hereby, including the costs and expenses incurred in relation to the incorporation of Newco, shall be borne by Newco.
