SCHEDULE 1: SERVICES AND FEES

PART 1: SERVICES

1. Services

1.1 Transaction Services

• Introducing the Company to Shire plc;

• Assisting, when requested by the Company, with the preparation of any documentation required for the Transaction including an information memorandum and management presentation,

• Providing advice on the structure and terms of the Transaction and assisting, when requested by the Company, with the evaluation and negotiation of the Transaction.

1.2 Our Services are subject to the following:

• Our involvement in the preparation and publication of any communication in connection with the Engagement does not constitute authorisation of the contents of that document or any part of it, save to the extent expressly stated in that document.

• Nothing in this Agreement requires us to provide specialist or technical advice (for example, on legal, regulatory, actuarial, accounting or taxation matters) which can be obtained from other professional advisors or for advising on the commercial aspects of the Transaction.

• It is your responsibility to ensure that the advice received from your other professional advisors in relation to the Transaction is adequate and to the requisite standard for the purposes of the Transaction. We can assume all such advice is adequate and of the requisite standard without taking independent steps to verify this.

• In particular, we are not responsible for carrying out any due diligence investigations on your behalf. You should rely on your own expertise and that of your other professional advisors in defining the scope of any due diligence exercise and in formulating and assessing its conclusions.

• Nothing we do in performing our services shall be construed as advice to proceed or not to proceed with the Transaction or any other transaction which may come within the scope of our advice. These are matters for commercial decision and are your responsibility. Whilst our advice may be a factor taken into account by you when deciding whether or not to proceed, regard must be had by you to the limitations on the scope of our advice as set out in this Agreement and/or any subsequent advice provided by you and any other factors, commercial or

otherwise, of which you and your other advisors are, or should be or become aware of other than our work.

Part 2: Fees for the Transaction

2.0   Fees

2.1 The Company agrees to pay Sudbrook a Success Fee of 2% of the cash and non-cash consideration received by the Company from Shire plc or its affiliates in connection with the Transaction (“Consideration”). Consideration shall include, but is not limited to, fees, milestones, royalties and licensing revenues and includes payment in cash, shares, loan stock or other non-cash consideration. Consideration shall also include any consideration paid to the Company in the event of a successful offer to acquire part or all of the issued share capital of the Company. Notwithstanding anything to the contrary contained herein, funds provided by Shire plc or its affiliates for the reimbursement or direct payment of research and development expenses, including, without limitation, employee costs and expenses, shall not be deemed to be Consideration and no Success Fee shall be due to Sudbrook in connection therewith.

A Success Fee with respect to any Consideration received by the Company shall be paid to Sudbrook within 30 days of the Company’s actual receipt of such Consideration. For example, if the Transaction provides for the payment of $1.0 million upon the achievement of a certain milestone and such milestone is achieved, then the Company shall pay to Sudbrook a $20,000 Success Fee within 30 days after the Company receives from Shire plc or its affiliates the $1.0 million milestone payment. In the event that such milestone is not achieved or Shire plc or its affiliates fails to make the milestone payment, the Company shall not be obligated to pay such Success Fee.

If any portion of the Consideration is paid in the form of securities, the value of such securities, for the purposes of calculating the Transaction Value, will be determined by the average of the closing prices, on the principal investment exchange on which, they are listed or dealt in, on the five trading days ending five days prior to the date the securities are issued to the Company, its affiliates or stockholders. If such securities are not traded on a public market at that time, the value of the securities shall be the fair market value on the day when the securities are issued to the Company, its affiliates or stockholders. If the fair market value cannot be agreed by both parties a valuation will be sought from a third party whose appointment is agreed by both Sudbrook and the Company.

2.2 All sums payable under this Agreement are exclusive of VAT (if any).

2.3 The Company must pay the above fees together with all VAT payable on them to Sudbrook.

SCHEDULE 2: INDEMNITY

1. Indemnity

1.1 The Company irrevocably agrees with Sudbrook (and for the benefit of the Indemnified Persons) that:

(A) it will fully indemnify and hold harmless Sudbrook and each other Indemnified Person from and against any and all actions, claims, demands, proceedings brought by any third party whether pending, threatened or actual and whether successful, compromised, settled or discontinued (collectively “Claims”) and any liabilities, losses, damages, costs, charges and expenses of whatever nature and in whichever jurisdiction (collectively “Losses”) which may be suffered or incurred by, Sudbrook or any other Indemnified Person as a result of such Claims and which relate to or arise from, directly or indirectly, the Engagement (including, without limitation, in relation to any financial promotion (as referred to in section 21, FSMA) distributed on the Company’s behalf);

(B) the Company will reimburse Sudbrook and any other Indemnified Person promptly on demand by Sudbrook or any such other Indemnified Person in full for all Losses incurred in connection with investigating, responding to, preparing for, defending or appearing as a witness in any such Claim, whether or not in connection with pending or threatened litigation, arbitration or other alternative dispute resolution procedures to which Sudbrook or any other Indemnified Person is a party or otherwise involved, and whether or not resulting in liability on the part of any such person, provided that Sudbrook and any other Indemnified Person wishing to claim under the indemnity in paragraph (A) above complies with the provisions of paragraph (C) below and that the Company will not be responsible for any Claims or Losses to the extent that (i) they are judicially determined to have arisen from Sudbrook’s fraud, wilful default or negligence (or that of an Indemnified Person) or the material breach by Sudbrook of its obligations to the Company under the Agreement or (ii) they arise as a result of a breach by Sudbrook or an Indemnified Person of its duties under the FSA Rules or under the regulatory system (as defined in such Rules);

(C) the indemnity given in paragraph (A) above is subject to Sudbrook or any other Indemnified Person wishing to claim the benefit of the indemnity: (i) notifying the Company in writing as soon as reasonably practicable of any Claim and providing full details of the same, (ii) allowing the Company a reasonable period of time to make representations as to the conduct of the defence, or the terms of compromise, settlement or dealing with any Claim (iii) at the Company’s expense, co-operating with the Company and giving all such information as the Company may request in connection with any Claim brought against Sudbrook or any Indemnified Person; and (iv) not taking any action which might prejudice the position of Sudbrook or any Indemnified Person or the Company in relation to any such Claim, in particular not, without the prior written consent of the Company, settling or compromising or consenting to the entry of any judgment with respect to any pending or threatened Claim in respect of which indemnification may be sought under this Schedule 2;

(D) no claim will be made against Sudbrook by the Company or any Associate of the Company in respect of the Engagement or the Agreement, and the Company will use all its reasonable endeavours to procure that no Claim will be made by any other person, except in each of these circumstances as a result of Sudbrook’s fraud, wilful default, negligence or breach of its obligations to the Company under the Agreement or as a result of a breach by Sudbrook or an Indemnified Person of its duties under the FSA Rules or FSMA or under the regulatory system (as defined in the FSA Rules), and neither Sudbrook nor any other Indemnified Person will have any liability whatsoever to the Company or any Associate of the Company for or in connection with the Engagement or the Agreement except to the extent that (i) such liability is judicially determined to have arisen from Sudbrook’s fraud, wilful default or negligence or breach of its obligations to the Company under the Agreement or (ii) results from a breach by Sudbrook or an Indemnified Person of its duties under the FSA Rules or under the regulatory system (as defined in the FSA Rules),

(E) Sudbrook will fully indemnify and hold harmless the Company, its Associates and any successor or assignee of any such person from and against Sudbrook’s fraud, wilful default, negligence or breach of its obligation to the Company under this Agreement (“Sudbrook Claims”) and any liabilities, losses, damages, costs, charges and expenses of whatever nature and in whichever jurisdiction (collectively “Losses”) which may be suffered or incurred by, the Company, its Associates and any successor or assignee of any such person as a result of such Sudbrook Claims, and shall provide reimbursement in connection with Sudbrook Claims, on the same terms, as the Company agrees to provide under the provisions of paragraph (B) in connection with Claims. The indemnity given in this paragraph (E) is subject to the terms of paragraph (C) as they may apply to such a Sudbrook Claim.

(F) nothing in this Schedule 2 shall restrict or limit the Company’s, Sudbrook’s or any Indemnified Person’s general obligation at law to mitigate a loss it may suffer or incur as a result of an event that may give rise to a claim under the indemnity in paragraph (A) or (E) above;

(G) all sums payable under this Schedule 2 must be paid free and clear of all deductions or withholdings unless the deduction or withholding is required by law, in which event the payee will pay such additional amount as to ensure that the net amount received by the payor will equal the full amount which would have been received by it had no such deduction or withholding been made;

(H) if HM Revenue & Customs or any other taxing authority brings into charge to tax any sum payable under this Schedule 2 by way of reimbursement or indemnity and no tax relief was available for the loss giving rise to the reimbursement or indemnity, the amount so payable shall be grossed up by such amount as ensures that after deduction of the tax so chargeable (ignoring for this purpose the availability of any reliefs or other deductions available to the payee) there shall be left a sum equal to the amount that would otherwise be payable as a result of such reimbursement or indemnity;

(I) References in this Schedule 2 to:

“Affiliate” means, in relation to a body corporate, any subsidiary undertaking or parent undertaking of that body corporate, and any subsidiary undertaking of any

Sudbrook agrees as follows with respect to all Confidential Information:

1. Sudbrook shall only use the Confidential Information for purposes of performing its obligations under the Engagement and shall obtain an executed confidentiality agreement, the form and substance of which has been previously approved by the Company in its sole discretion, from each and every party to which Sudbrook desires to evaluating, making, monitoring and disposing of investments in the Company, and shall not use the Confidential Information for any other purposes.

2. Sudbrook shall treat all Confidential Information as the strictly confidential and exclusive property of the Company, and shall not directly or indirectly disclose or distribute such Confidential Information to any third party (except as provided in paragraphs 1 above).

6. Sudbrook will upon written request from the Company promptly return or destroy all copies of any documents, samples or other physical embodiments of the Confidential Information to the Company.

7.

(i)           use Confidential Information to deal or encourage any other person to deal in securities of Medgenics.

For the purposes of the foregoing the term “deal” is to be construed in accordance with the said Criminal Justice Xxx 0000;

(ii)           (and will procure that each of Sudbrook’s affiliates and subsidiaries will and will use its best efforts to procure that none of their respective related, connected or associated parties will) without Medgenics’ prior written consent directly or indirectly by purchase or otherwise, acquire (conditionally or otherwise), offer to acquire, or agree to acquire ownership or options to acquire such ownership or any rights whatsoever in respect of any share capital in Medgenics (or otherwise act in concert with any person who so acquires, offers to acquire or agrees to acquire) within twelve months from the date of the Agreement.
