Based on the information such Purchaser has deemed appropriate, and without reliance upon the Placement Agent, it has independently made its own analysis and decision to enter into the Transaction Documents.

The Company further covenants and agrees that it shall (and shall cause each of its subsidiaries and affiliates to) implement and maintain systems of internal controls (including, but not limited to, accounting systems, purchasing systems and billing systems) to ensure compliance with the FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti- corruption law consistent and appropriate for the size of the Company and the scope of its operations.

(o) Non-Public Information. The Company covenants and agrees that, for so long as any Purchaser holds at least 1% of the outstanding Ordinary Shares, neither the Company, nor any other person authorized to act on its behalf, will provide any Purchaser or its agents or counsel with any information that the Company reasonably believes constitutes material non-public information (including, for so long as the Ordinary Shares are admitted to trading on AIM, “inside information” as defined under MAR), unless prior thereto such Purchaser shall have consented to the receipt of such information and agreed with the Company to keep such information confidential, or otherwise in compliance with MAR.

(p) Certain Transactions and Confidentiality.

Any agreement on the part of a party to any extension or waiver will be valid only if set forth in an instrument in writing signed by such party. The failure of any party to assert any of its rights under this Agreement or otherwise will not constitute a waiver of such rights.

9. INDEMNIFICATION.

(a) Company Indemnification Obligation. The Company shall to the fullest extent permitted by applicable law, including the Companies Xxx 0000, indemnify and hold harmless each Purchaser and its directors, officers, shareholders, members, managers, employees, partners and any of the foregoing Persons’ agents or other representatives (including those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith, and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitees as a result of, or relating to (i) any material breach (or, in the case of any representation already qualified by materiality, Material Adverse Effect or similar materiality qualifier, any breach) of any representation or warranty made by the Company herein, or (ii) any material breach (or, in the case of any covenant, agreement or obligation already qualified by materiality, Material Adverse Effect or similar materiality qualifier, any breach) of any covenant, agreement or obligation of the Company herein; provided, that the Company shall not be required to indemnify any Indemnitee in respect of any Indemnified Liabilities to the extent that such liability resulted primarily from such Indemnitee’s gross negligence, willful misconduct or fraud or to the extent that a loss, claim, damage or liability is attributable to such Purchaser’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser in any Transaction Document. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall contribute to the amount paid or payable by the Indemnitees as

a result of such Indemnified Liabilities as is appropriate to reflect the relative fault of the Company, on the one hand, and such Indemnitee, on the other hand. The maximum aggregate liability of the Company to each Purchaser and such Purchaser’s directors, officers, shareholders, members, managers, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives shall be equal to the Purchase Price paid by such Purchaser for Units, as set forth on Exhibit A-1.

(b) Indemnification Procedures. Each Indemnitee shall (i) give prompt written notice to the Company of any claim with respect to which it seeks indemnification or contribution pursuant to this Agreement (provided, however, that the failure of the Indemnitee to promptly deliver such notice shall not relieve the Company of any liability, except to the extent that the Company is actually and materially prejudiced in its ability to defend such claim) and (ii) permit the Company to assume the defense of such claim with counsel selected by the Company and reasonably satisfactory to the Indemnitee; provided, however, that any Indemnitee entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of the Indemnitee unless (A) the Company has agreed in writing to pay such fees and expenses, (B) the Company shall have failed to assume the defense of such claim within five Business Days of delivery of the written notice of the Indemnitee with respect to such claim or failed to employ counsel selected by the Company and reasonably satisfactory to the Indemnitee, or (C) in the reasonable judgment of the Indemnitee, based upon advice of outside counsel, a conflict of interest exists between the Indemnitee and the Company with respect to such claims (in which case, if the Indemnitee notifies the Company in writing that it elects to employ separate counsel at the expense of the Company, the Company shall not have the right to assume the defense of such claim on behalf of the Indemnitee). If the Company assumes the defense of the claim, the Company shall not be subject to any liability for any settlement or compromise made by the Indemnitee without its consent. In connection with any settlement negotiated by the Company, the Company shall not, and no Indemnitee shall be required by the Company to, (i) enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to the Indemnitee of a release from all liability in respect to such claim or litigation, (ii) enter into any settlement that attributes by its terms any liability, culpability or fault to the Indemnitee, or (iii) consent to the entry of any judgment that does not include as a term thereof a full dismissal of the litigation or proceeding with prejudice. If the Company fails or elects not to assume the defense of a claim pursuant to clause (B) above, or is not entitled to assume or continue the defense of such claim pursuant to clause (C) above, the Indemnitee shall have the right without prejudice to its right of indemnification hereunder to, in its discretion exercised in good faith and upon advice of counsel, to contest, defend and litigate such claim; provided, however, the Indemnitee may not settle such claim without the prior written consent of the Company. If requested by the Company, the Indemnitee agrees (at no expense to the Indemnitee) to reasonably cooperate with the Company and its counsel in contesting any claim that the Company elects to contest.

10. GOVERNING LAW; MISCELLANEOUS.

for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. By the execution and delivery of this Agreement, the Company hereby agrees to, as promptly as practicable but in no event later than one (1) Business Day following the Closing Date, appoint Mereo US Holdings Inc., a Delaware corporation, as its agent upon which process may be served in any legal action or proceeding which may be instituted in any federal or state court in the City of New York, borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, but for that purpose only. Such appointment shall be irrevocable so long as any Purchaser shall have any rights pursuant to the terms hereof until the appointment of a successor by the Company with the consent of the Purchasers and such successor’s acceptance of such appointment. The Company further agrees to take any and all actions, including the execution and filing of any and all such documents and instruments, as may be necessary to continue such designation and appointment of such agent or successor. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction. Each of the parties hereto hereby expressly and irrevocably waives all rights of jurisdiction in any jurisdiction other than the state and federal courts sitting in the City of New York, borough of Manhattan, in any such suit, action or proceeding which it may now or hereafter be afforded by law in any other forum other than the state and federal courts sitting in the City of New York, Borough of Manhattan. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

(b) Counterparts; Execution. This Agreement may be executed in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts shall together constitute one and the same instrument. Each of the parties hereto (i) has agreed to permit the use, from time to time, of faxed or otherwise electronically transmitted signatures (including by PDF) in order to expedite the consummation of the transactions contemplated hereby, (ii) intends to be bound by its respective faxed or otherwise electronically transmitted signature, (iii) is aware that the other parties hereto will rely on the faxed or otherwise electronically transmitted signature, and (iv) acknowledges such reliance and waives any defenses to the enforcement of the documents effecting the transaction contemplated by this Agreement based on the fact that a signature was sent by fax or otherwise electronically transmitted.

(c) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

(d) Severability. If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.

This Agreement, including the Exhibits and Schedules hereto, together with the Notes, the Warrants and the Registration Rights Agreement, supersedes all other prior oral or written agreements among each Purchaser, the Company, their respective Affiliates and Persons acting on their behalf with respect to the matters provided for herein, and this Agreement, including the Exhibits and Schedules hereto, contains the entire understanding of the parties hereto with respect to the matters covered herein. No provision of this Agreement may be waived, modified, supplemented or amended other than by an instrument in writing signed by the Company and the Requisite Purchasers. Any such amendment shall bind all Purchasers. No such amendment shall be effective to the extent that it applies to less than all of the Purchasers. Notwithstanding the foregoing, this Agreement may not be amended or terminated and the observance of any term hereof may not be waived with respect to any Purchaser without the written consent of such Purchaser, unless such amendment, termination, or waiver applies to all Purchasers in the same fashion. No failure or delay on the part of a party in either exercising or enforcing any right under this Agreement shall operate as a waiver of, or impair, any such right. No single or partial exercise or enforcement of any such right shall preclude any other or further exercise or enforcement thereof or the exercise or enforcement of any other right. No waiver of any such right shall be deemed a waiver of any other right.

(f) Notices. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by e-mail (provided confirmation of transmission is mechanically or electronically generated and a read receipt is received, and in each case kept on file by the sending party); or (iii) upon receipt, when delivered by nationally recognized overnight delivery service (as evidenced by written confirmation of receipt), in each case properly addressed to the party to receive the same.

(h) No Third Party Beneficiaries.

The representations and warranties of the Company and Purchasers contained herein shall survive the Closing and shall remain in full force and effect until the date that is 30 days following the date on which the Company publishes its Annual Report and Accounts for the fiscal year ending December 31, 2021.

(j) Further Assurances.

(k) Placement Agent. The Company acknowledges that it has engaged SVB Leerink LLC as placement agent in the offering documented by this Agreement (the “Placement Agent”), and the Company shall be solely responsible for the payment of all fees and expenses to the Placement Agent. Each Purchaser hereby acknowledges and agrees that (a) the Placement Agent is acting solely as placement agent in connection with the execution, delivery and performance of the Transaction Documents and is not acting as an underwriter or in any other capacity and is not and shall not be construed as a fiduciary for any Purchaser, the Company or any other person or entity in connection with the execution, delivery and performance of any Transaction Document, (b) the Placement Agent has not made and will not make any representation or warranty, whether express or implied, of any kind or character, and has not provided any advice or recommendation in connection with the execution, delivery and performance of any Transaction Document, (c) the Placement Agent will not have any responsibility with respect to (i) any representations, warranties or agreements made by any person or entity under or in connection with the execution, delivery and performance of any Transaction Document, or the execution, legality, validity or enforceability (with respect to any person) thereof, or (ii) the business, affairs, financial condition, operations, properties or prospects of, or any other matter concerning the Company, and (d) the Placement Agent will not have any liability or obligation (including without limitation, for or with respect to any losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements incurred by any Purchaser, the Company or any other person or entity), whether in contract, tort or otherwise, to any Purchaser, or to any person claiming through it, in respect of the execution, delivery and performance of any Transaction Document.

(l) Expenses. Each Purchaser shall be responsible for all fees and charges of the Depositary related to any issuance of ADSs in connection with this Agreement.

(m) Independent Nature of Purchasers. The obligations of each Purchaser hereunder are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser hereunder. Each Purchaser shall be responsible only for its own representations, warranties, agreements and covenants hereunder. The decision of each Purchaser to purchase the Units pursuant to this Agreement has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Group Companies which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any other Purchaser (or any other Person or entity) relating to or arising from any such information, materials, statements or opinions. Each Purchaser is represented by its own legal representative and is not relying upon the legal representative of the Lead Purchaser or any other Purchaser. Nothing contained herein, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated hereby. Each Purchaser shall be entitled to independently protect and enforce its rights, including the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

(n) Confidentiality. The parties to this Agreement shall keep, and shall have their respective Affiliates, employees and other representatives keep, the contents of this Agreement, the transactions contemplated hereby and the negotiations and possible proceedings in relation hereto confidential indefinitely, except as required for the conclusion of this Agreement or by any relevant laws or applicable stock exchange rules, and provided, that the Company shall be permitted to disclose the existence and the main contents of this Agreement (i) in the Resale Registration Statement, (ii) by way of public announcement on signing under the AIM Rules, (iii) in the Shareholder Circular, (iv) in any further public announcement required by the AIM Rules or any other applicable law or regulation to which the Company is subject, and (v) the Company’s Shareholders Meeting, and provided further, that all parties shall be permitted to share such information with their financial and legal advisors.

(o) Interpretative Matters. Unless the context otherwise requires, (i) all references to Sections, Schedules or Exhibits are to Sections, Schedules or Exhibits contained in or attached to this Agreement; (ii) the words describing the singular number shall include the plural and vice versa; (iii) words denoting either gender shall include both genders and words denoting natural Persons shall include all Persons and vice versa; (iv) the words “hereof,” “herein,” “hereby,” “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement; (v) whenever the words “include,” “includes” or “including” are used in this Agreement they shall be deemed to be followed by the words “without limitation”; (vi) the phrases “the date of this Agreement,” “the date hereof,” “of even date herewith” and terms of similar import, shall be deemed to refer to the date set forth in the preamble to this Agreement; and (vii) any reference in this Agreement to a date or time shall be deemed to be such date or time in the City of New York, New York, unless otherwise specified. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties and no presumption or burden of proof shall arise favoring or disfavoring any Person by virtue of the authorship of any provision of this Agreement. The omission of any indemnification obligations of the Purchasers in Section 9 shall not be deemed to constitute a waiver by the Company of any of its rights or remedies with respect to any breach by the Purchasers of their representations, warranties, covenants or agreements hereunder.

(p) Judgment Currency. If any judgment under this Agreement is rendered in U.S. dollars and, in order to obtain or enforce such judgment in any court of competent jurisdiction, it becomes necessary to convert an amount denominated in U.S. dollars into any other currency (the “Judgment Currency”), the conversion of the amount of the U.S. dollar-denominated judgment into the Judgment Currency shall be made at the rate of exchange by a known dealer in U.S. dollars determined as of the day on which the applicable judgment is rendered.

4.2

Subject to paragraph 4.12 below, in the event that Shareholder Approval has not been obtained on or before 7 August 2020, in addition to the amounts otherwise payable on the Redemption Date, each Noteholder holding any Tranche 1 Notes shall be entitled to be paid an additional sum on the Redemption Date, the amount of which shall be equal to the principal amount of the Tranche 1 Notes outstanding on 7 August, 2020 and held by such Noteholder in recognition of such Noteholder not being able to (i) participate in the equity of the Company through conversion of the Tranche 1 Notes, or (ii) benefit from any Warrants that were intended to be issued to such Tranche 1 Noteholder as part of the Transaction (such sum being the “Uplift Payment”). Notwithstanding the foregoing, in the event that Shareholder Approval has not been obtained on or before 7 August 2020, upon conversion of the Notes in accordance with Part 2 of Schedule 2, the Noteholder shall be entitled to the benefit of the Uplift Payment. In the event that the Shareholder Approval has not been obtained on or before 7 August 2020 and a Noteholder did not attend (either in person or by proxy) any general meeting of the Company’s members called for the purposes of obtaining the Shareholder Approval and vote in favour of such Shareholder Approval with the entirety of all voting rights available to such Noteholder, such Noteholder shall cease to be entitled to the benefit of the Uplift Payment in any circumstances.

4.4	The amount of the Uplift Payment to be satisfied by the Uplift Securities shall be calculated by: multiplying (x) being the number of Uplift Securities the Company wishes to issue, by (y) being the Tranche 1 Conversion Price (the “Uplift Reduction Amount”).

4.5	The Uplift Allocation Notice served pursuant to paragraph 4.3 above shall specify, at a minimum:

(a)

the number of Uplift Securities the Company proposes to issue;

(b)

each Tranche 1 Noteholder’s current percentage holding of the aggregate voting rights in the Company; and

(c)

the issue date of the Uplift Securities (which shall in all cases be within 5 Business Days of the date the Uplift Allocation Notice was served).

4.6	In the event that:

(a)

there is only one Tranche 1 Noteholder, that Noteholder shall be automatically deemed to have subscribed for the maximum number of Uplift Securities as it is possible to subscribe without the Ownership Limit of that Tranche 1 Noteholder being exceeded; and

(b)

if there is more than one Tranche 1 Noteholder, each Tranche 1 Noteholder shall be automatically deemed to have subscribed (and such subscription shall be deemed satisfied out of each Tranche 1 Noteholder’s entitlement to the Uplift Payment) for such number of Uplift Securities as is determined pro rata to each Tranche 1 Noteholder’s proportionate entitlement to the Uplift Payment (provided that such amount does not result in the Ownership Limit being exceeded, and if it was to so result, such Tranche 1 Noteholder shall be required to subscribe for the maximum amount of Uplift Securities that such Tranche 1 Noteholder could receive without being in breach of the Ownership Limit, any excess Uplift Securities would then be allocated to each other Tranche 1 Noteholder (who would be deemed to subscribe for the same) pro rata to their entitlement to the Uplift Payment until either all Uplift Securities have been allocated amongst all Tranche 1 Noteholders or all Tranche 1 Noteholders have each reached the Ownership Limit),

and in each case the Company shall issue such Uplift Securities (which shall be credited as fully paid and rank pari passu with Ordinary Shares of the same class in issue on the Conversion Date) within 5 Business Days of the Uplift Allocation Notice and the applicable Tranche 1 Noteholder’s entitlement to the Uplift Payment shall thereon be reduced by their proportion of the Uplift Reduction Amount.

4.7

At any time when (i) the Company has satisfied the entirety of its obligations in respect of the Uplift Payment through the issue of Uplift Securities pursuant to paragraphs 4.3 to 4.6 above (or the Uplift Payment has otherwise been discharged or waived); (ii) the Closing Price is above the Tranche 1 Conversion Price, and (iii) the Company has authority from its shareholders to allot additional Ordinary Shares; the Company may notify all (but not some) of the Tranche 1 Noteholders that it wishes to satisfy its obligations in respect of an amount of interest and/or principal under the Tranche 1 Notes by the issuance of further Ordinary Shares pro rata to all Tranche 1 Noteholders (such Ordinary Shares being “Pay Down Securities”) (such notice a “Pay Down Notice” and such process a “Pay Down Issue”).

4.8

The amount of principal and interest in respect of the Tranche 1 Notes to be satisfied by the issue of Pay Down Securities shall be calculated by: multiplying (x) being the number of Pay Down Securities the Company wishes to issue, by (y) being the Tranche 1 Conversion Price (the “Pay Down Reduction Amount”).

4.9	The Pay Down Notice served on each Tranche 1 Noteholder pursuant to paragraph 4.7 above shall specify, at a minimum:

(a)

the number of Pay Down Securities the Company proposes to issue;

(b)

each Tranche 1 Noteholder’s current percentage holding of the aggregate voting rights in the Company; and

(c)

the issue date of the Pay Down Securities (which shall in all cases be within 5 Business Days of the date the Pay Down Notice was served).

4.10	In the event that:

(a)

there is only one Tranche 1 Noteholder, that Tranche 1 Noteholder shall be automatically deemed to have subscribed for the maximum number of Pay Down Securities as it is possible to subscribe without the Ownership Limit of that Tranche 1 Noteholder being exceeded; and

(b)

there is more than one Tranche 1 Noteholder, each Tranche 1 Noteholder shall be automatically deemed to have subscribed (and such subscription shall be deemed satisfied out of each Tranche 1 Noteholder’s entitlement to principal and/or interest under the Notes) for the maximum amount of Pay Down Securities that such Tranche 1 Noteholder could receive without being in breach of the Ownership Limit, any excess Pay Down Securities would then be allocated to each other Tranche 1 Noteholder (who would be deemed to subscribe for the same) pro rata to their entitlement outstanding interest and/or principal under the Tranche 1 Notes until either all Pay Down Securities have been allocated amongst all Tranche 1 Noteholders or all Tranche 1 Noteholders have each reached the Ownership Limit,

and in each case the Company shall issue such Pay Down Securities (which shall be credited as fully paid and rank pari passu with Ordinary Shares of the same class in issue on the Conversion Date) within 5 Business Days of the Pay Down Notice and the applicable Tranche 1 Noteholder’s entitlement to principal amount and/or interest shall thereon be reduced by their proportion of the Pay Down Reduction Amount.

4.11

At any time when (i) the Company has satisfied all principal and interest outstanding in respect of the Tranche 1 Notes by the issue of Pay Down Securities; (ii) the Closing Price is above the Tranche 2 Conversion Price, and (iii) the Company has authority from its shareholders to allot additional Ordinary Shares, the Company may serve a Pay Down Notice on the Tranche 2 Noteholders, notifying them it wishes to satisfy its obligations in respect of any interest and/or principal amount under the Tranche 2 Notes by way of a Pay Down Issue, and the provisions of the foregoing paragraphs 4.7 to 4.10 above shall apply mutatis mutandis in respect of any such Pay Down Issue in respect of the Tranche 2 Notes (and in such circumstances, for the avoidance of doubt, (y) for the purposes of calculating the Pay Down Reduction Amount pursuant to paragraph 4.8 shall be the Tranche 2 Conversion price). At any time when (i) the Company has satisfied all principal and interest outstanding in respect of the Tranche 2 Notes by the issue of Pay Down Securities; and (ii) the Company has authority from its shareholders to allot additional Ordinary Shares, the Company may serve a Pay Down Notice on the Tranche 3 Noteholders, notifying them it wishes to satisfy its obligations in respect of any interest and/or principal amount under the Tranche 3 Notes by way of a Pay Down Issue, and the provisions of the foregoing paragraphs 4.7 to 4.10 above shall apply mutatis mutandis in respect of any such Pay Down Issue in respect of the Tranche 3 Notes (and in such circumstances, for the avoidance of doubt, (y) for the purposes of calculating the Pay Down Reduction Amount in respect of Tranche 3 Notes pursuant to paragraph 4.8 shall be the weighted average of the Closing Price on the 5 Business Days immediately prior to the date on which the Pay Down Notice is served in respect of such Tranche 3 Notes).

4.12

In the event that (i) a Change of Control occurs on or prior to 7 August 2020 and Shareholder Approval has not been obtained on or prior to the date of such Change of Control; or (ii) Shareholder Approval has not been obtained on or before 7 August 2020 and following 7 August 2020 but prior to the Tranche 1 Maturity Date, the Company undergoes a Change of Control; in either case the Company shall pay or cause to be paid, within 3 Business Days of the date on which consideration in respect of such Change of Control is remitted to the holders of Ordinary Shares, to each Noteholder, in addition to the sum payable pursuant to paragraph 4.1(b) of this Part 1 of Schedule 2, an additional sum, the amount of which shall be equal to the value of (a) minus ((b), (c) and (d)), where:

(a)

is the pro rata amount of consideration which would have been received by such Noteholder in consideration for their Ordinary Shares and Warrants (plus, to the extent they exist, any Tranche 3 Notes held by such Noteholder but without double-counting in respect of the value of any Warrants that were converted into such Tranche 3 Notes by the Noteholder) on the Change of Control if that Shareholder Approval had been obtained on or prior to 7 August 2020 and as a result (i) all the Warrants held by such Noteholder as of the date of the Change of Control had become fully exercisable on or prior to 7 August 2020; and (ii) all Tranche 1 Notes held by such Noteholder as of the date of the Change of Control had automatically converted into Ordinary Shares upon receipt of the Shareholder Approval; and

(b)

is the aggregate of the principal amount of such Noteholder’s Tranche 1 Notes, together with any accrued but unpaid interest thereon held by such Noteholder immediately prior to the Notes being redeemed pursuant to paragraph 4.1(b) of this Part 1 of Schedule 2; and

(c)

is the pro rata amount of consideration actually received or due to be received by such Noteholder pursuant to Section 2.10 of the Warrant Instrument in respect of Warrants held by such Noteholder as of the date of such Change of Control; and

(d)

is the pro rata amount of consideration actually received or due to be received by such Noteholder (whether on or prior to any Change of Control) in respect of any Ordinary Shares received by such Noteholder in exchange for Tranche 1 Notes pursuant to paragraphs 4.7 through 4.11 of this Schedule 2;

(such sum being the “Change of Control Payment”). For the avoidance of doubt, if any Noteholder becomes entitled to be paid the Change of Control Payment, such Noteholder shall cease to be entitled to the Uplift Payment pursuant to paragraph 4.2.

4.13

Subject to paragraph 6 if the Noteholder Majority wishes to redeem the Notes following an Acceleration Date, the Noteholder Majority shall give the Company written notice of the intention to exercise the right to redeem in accordance with the provisions of paragraph 4.1(b), together with confirmation on the date for such redemption (provided that such date may not occur earlier than the date falling 20 Business Days after the relevant Acceleration Date), conditional always on any such Event of Default not being remedied in the case of paragraph 4.1(c) (“Redemption Notice”).

4.14	A Redemption Notice shall (unless the Company agrees otherwise) be irrevocable.

4.15

For as long as the Subordination Agreement is in force, notwithstanding any of the provisions of paragraph 5 of this Part 1 of Schedule 2, the Notes cannot be redeemed or repaid following an Acceleration Date until the applicable restriction in the Subordination Agreement has expired or been waived by the Senior Lenders; provided that such delay in payment shall constitute an additional Event of Default hereunder.

4.16	On the Redemption Date, the Company shall repay to all Noteholders the principal amount of the Notes so redeemed, together with interest on such Notes outstanding at the applicable Interest Rate, and, if applicable, the Uplift Payment payable pursuant to paragraph 4.2.

4.17

If, on redemption of a Note, a Noteholder fails to deliver the Certificate for it, or an indemnity in accordance with these Conditions or to accept payment of moneys due to him, the Company shall pay the moneys due to him into bank account which payment shall discharge the Company from all further obligations in respect of the Note.

4.18	The Company shall cancel any Notes repaid, redeemed or purchased and shall not reissue them.

5.	EVENTS OF DEFAULT

Subject to paragraphs 4.15 and 6.3 of this part 1 of Schedule 2, the Notes then in issue shall become immediately redeemable at the principal amount, together with interest on the Notes outstanding, and interest shall become payable at the applicable Default Rate, if:

(a)

the Company fails to pay any interest or principal in respect of the Notes on the relevant due date;

(b)

the Company fails to comply in any material respect with the covenants of the Notes or any of the Conditions and does not remedy such failure within 30 calendar days;

(c)

any judgment, arbitration award, order or decree for the payment of money and that is no longer subject to an appeal process in an amount, individually or in the aggregate of at least £1,000,000 (or its equivalent in other currencies) is rendered against any Group Company and not cured or withdrawn within 30 calendar days of such judgment, award, order or decree;

(d)

a Group Company incurs an Event of Default (as such term is defined in the Novartis Loan Note) pursuant to the terms of the Novartis Loan Note and such Event of Default is not remedied within the greater of (i) any applicable grace period pursuant to the terms of the Novartis Loan Note; and (ii) 30 days from the occurrence of such Event of Default; and results in the acceleration by Novartis of any indebtedness owed pursuant to the terms of the Novartis Loan Note;

(e)

a Group Company incurs an event of default (howsoever defined) in respect of any indebtedness in a principal amount in excess of £1,000,000 and fails to cure (or have waived) such event of default within 30 calendar days of such event of default;

(f)

a Group Company commits a material breach of any material contract to which such Group Company is a party and fails to cure (or have waived) such material breach within 30 calendar days of such event of default

(g)

an encumbrancor takes possession or a receiver is appointed of the whole or the major part of the assets or undertaking of a Group Company or if distress, execution or other legal process is levied or enforced or sued out on or against the whole or the major part of the assets of any Group Company and is not discharged, paid out, withdrawn or removed within 30 calendar days;

(h)

a Group Company is the subject of any proceeding in bankruptcy or for their dissolution, liquidation, winding-up, composition or other relief under any applicable insolvency or bankruptcy laws, whether voluntary or involuntary and, if involuntary, is not dismissed within 60 calendar days of filing;

(i)

an administration order is made in relation to any Group Company; or

(j)

an order is made, or an effective resolution is passed, for the winding-up, liquidation, administration or dissolution of any Group Company (except for the purpose of reorganisation or amalgamation of the Group Companies).

6.	ACTION FOLLOWING EVENT OF DEFAULT

6.1	The Company shall give written notice to the Noteholders as soon as reasonably practicable following the Company becoming aware of the occurrence of an event specified in paragraph 5, giving reasonable details of that event.

6.2

Following receipt of the notice provided pursuant to paragraph 6.1 above, and, if applicable, the expiry of any cure period provided for such Event of Default, the Noteholders shall have a period of 10 Business Days in which they may exercise their right to waive such Event of Default by Noteholder Majority Consent.

6.3

If the Noteholder Majority waives any Event of Default then the Notes shall cease to be immediately redeemable, and no further interest shall accrue at the applicable Default Rate in respect of such Event of Default (for the avoidance of doubt, notwithstanding such waiver, the Noteholders’ shall remain entitled to any interest accrued at the applicable Default Rate between the date of the Event of Default and the date of waiver by the Noteholder Majority).

7.	TAXATION

7.1

All payments to be made by the Company to a Noteholder under the Note shall be made free and clear of and without any deduction or withholding for or on account of tax (a “Tax Deduction”), unless a Tax Deduction is required by law. If a Tax Deduction is required by law, the amount of the payment due from the Company shall be increased to an amount which (after making any Tax Deduction) leaves an amount equal to the payment which would have been due if no Tax Deduction had been required.

7.2

Each Noteholder shall, in consultation with the Company, take all reasonable steps to mitigate any circumstances which arise and which would result in any amount becoming payable under or pursuant to paragraph 7.1 above, including (but not limited to) transferring its rights and obligations under this Instrument and the Notes to another affiliate of such Noteholder and permitting the listing of the Notes on a recognised stock exchange.

7.3	Paragraph 7.2 above does not in any way limit the obligations of the Company under this Instrument.

7.4

Each Noteholder and the Company shall co-operate in completing any procedural formalities necessary for the Company to obtain authorisation to make that payment without a Tax Deduction including using commercially reasonable endeavours to procure that investors in such Noteholder complete such procedural formalities.

7.5	If the Company makes an increased payment under paragraph 7.1 (a “Tax Payment”) and the relevant Noteholder shall (and shall use commercially reasonable endeavours to procure that investors will) co-operate with the Company to take any reasonable steps to:

(a)

investigate the availability of any credit against, relief or remission for, or repayment of any Tax is attributable to that increased payment of which that Tax Payment forms part, to that Tax Payment or to a Tax Deduction in consequence of which that Tax Payment was required (“Tax Credit”); and

(b)

obtain and/or utilise that Tax Credit,

and the Noteholder shall (and shall use commercially reasonable endeavours to procure that investors will) pay an amount to the Company which that Noteholder (or investors as applicable) determines (acting reasonably) will leave it (after that payment) in the same after-Tax position as it would have been in had some or all of the Tax Payment not been required to be made by the Company.

Part 2. Conversion

1.	CONVERSION

1.1	Without prejudice to the provisions paragraphs 4.3 to 4.11 of Schedule 2 Part 1, the Notes shall not be capable of conversion prior to Shareholder Approval having been obtained and no Noteholder shall serve any Conversion Notice prior to such time.

1.2

Subject to paragraph 1.1 and paragraph 1.4 of this Part 2 of Schedule 2, all outstanding Tranche 1 Notes shall automatically convert into a number of fully paid Ordinary Shares upon Shareholder Approval being obtained, determined by dividing (x) the sum of (i) the outstanding principal amount, plus (ii) all accrued and unpaid interest thereon, plus (iii) any amount of the Uplift Payment (to the extent the same is applicable pursuant to the terms of this Instrument) which has become due and payable in accordance with paragraph 4.2 and has not already been paid or satisfied by the issue of Uplift Securities (or otherwise), by (y) the Tranche 1 Conversion Price then in effect; provided that (but subject to paragraph 1.4 of this Part 2 of Schedule 2 below) following such conversion, no individual Noteholder shall hold more than 9.99% of the aggregate voting rights in the Company (on a fully diluted basis) (the “Ownership Limit”). In the event that Conversion of any Noteholder’s holding of Notes would result in such Noteholder exceeding the Ownership Limit, the principal amount of the Notes held by such Noteholder which shall convert shall be the greatest amount possible without that Noteholder exceeding such Ownership Limit and the remaining principal balance on such Notes shall remain outstanding.

1.3	Subject to paragraphs 1.1, 1.2 and 1.4 of this Part 2 of Schedule 2:

(a)

each Noteholder holding Tranche 1 Notes shall have the right, at any time prior to the Tranche 1 Maturity Date, to serve a Conversion Notice on the Company to convert all or, if the Ownership Limit applies, part of such Noteholder’s Tranche 1 Notes then outstanding (together with any accrued but unpaid interest thereon) into fully paid Ordinary Shares at the Tranche 1 Conversion Price per Share; and

(b)

each Noteholder holding Tranche 2 Notes shall have the right, at any time prior to the Tranche 2 Maturity Date applicable to such Noteholder’s Tranche 2 Notes, to serve a Conversion Notice on the Company to convert all or, if the Ownership Limit applies, part of such Noteholder’s Tranche 2 Notes then outstanding (together with any accrued but unpaid interest thereon) into fully paid Ordinary Shares at the Tranche 2 Conversion Price per Share,

provided that, in each of the foregoing cases, at the time of the Conversion Notice, either (i) such Noteholder’s aggregate voting rights in the Company is not in excess of the Ownership Limit and would not become in excess of the Ownership Limit as a result of the conversion contemplated by such Conversion Notice; or (ii) such Noteholder has waived the application of the Ownership Limit in accordance with paragraph 1.4 of this Part 2 of Schedule 2.

1.4

Notwithstanding the foregoing, a Noteholder may increase or decrease the Ownership Limit to any other percentage, by written notice to the Company; provided, that the Noteholder may not decrease the limitation prior to August 8, 2020; provided further that a waiver by the Noteholder of the Ownership Limit or a request to increase the Ownership Limit requires not less than 61 days prior written notice to the Company (with such waiver of the Ownership Limit or request to increase the Ownership Limit taking effect only upon the expiration of such 61 day notice period and applying only to the Noteholder and not to any other holder of Notes) and that such Ownership Limit shall never be increased above 19.99%.

1.5	The Conversion Notice shall set out, at a minimum:

(a)

the principal amount of the Tranche 1 Notes and/or Tranche 2 Notes to be converted;

(b)

the amount (if any) of accrued but unpaid interest on such principal amount which is to be converted;

(c)

the Noteholder’s current percentage holding of the aggregate voting rights in the Company;

(d)

the Conversion Date; and

(e)

any conditions (if any) applicable to the conversion and agreed in writing in advance by the Company.

1.6	The Service of a Conversion Notice shall be irrevocable and binding on the Noteholder.

2.	PROCEDURES ON CONVERSION

2.1

Subject to paragraph 1.1 of this Part 2 of Schedule 2, on the Conversion Date, the Directors shall convert the principal amount of the Notes and accrued but unpaid interest and any amount of the Uplift Payment (to the extent the same is applicable pursuant to the terms of this Instrument) which has become due and payable in accordance with paragraph 4.2 and has not already been paid or satisfied by the issue of Uplift Securities (or otherwise), into such number of new fully paid Ordinary Shares at the applicable Tranche 1 Conversion Price or Tranche 2 Conversion Price (as the case may be) as set out in paragraph 1 of this Part 2 of Schedule 2 in accordance with the following provisions of paragraph 2.2 to paragraph 2.5 (inclusive).

2.2

Conversion of the Notes shall be effected by the Company redeeming the relevant Notes on the Conversion Date. Each Noteholder whose Notes are being converted shall be deemed to irrevocably authorise and instruct the Company to apply the redemption moneys payable to that Noteholder in subscribing for Ordinary Shares on conversion of the Notes.

2.3

Ordinary Shares arising on conversion of the Notes (and any applicable accrued but unpaid interest) shall be issued and allotted by the Company on the Conversion Date and the certificates (if physical certificates are requested by such Noteholder) for such Ordinary Shares shall be despatched to the persons entitled to them at their own risk.

2.4

The Ordinary Shares arising on conversion of the Notes shall be credited as fully paid and rank pari passu with Ordinary Shares of the same class in issue on the Conversion Date and shall carry the right to receive all dividends and other distributions declared, made or paid after the Conversion Date.

2.5	The entitlement of each Noteholder to a fraction of a Share shall be rounded down to the nearest whole number of Ordinary Shares which result from the conversion of the Notes.

2.6

In the event that the Ordinary Shares in issue on the Conversion Date are traded on the AIM Market operated by London Stock Exchange plc, the Company shall use its reasonable best endeavours to ensure that the Ordinary Shares to be issued upon the conversion of the relevant Notes are admitted to trading on the AIM Market as soon as reasonably practicable following the Conversion Date. In addition, as soon as practicable following the general meeting at which the Company seeks to obtain Shareholder Approval, the Company shall make or cause to be made an application to AIM for a block listing (up to the maximum amount available to the Company under AIM block listing rules and in consideration of block listings registered at the time of this Agreement) or otherwise to admit upon Admission or as soon as permitted by AIM thereafter the maximum number of Ordinary Shares that may be acquired upon conversion of the Notes. Further, the Company shall list the Ordinary Shares issuable upon conversion of the Notes on each other securities exchange on which the Ordinary Shares are then listed and/or admitted to trading.

Part 3. Transfer provisions, Undertakings and other matters

The Company shall recognise the registered holder of any Notes as the absolute owner of them and shall not (except as provided by statute or as ordered by a court of competent jurisdiction) be bound to take notice or see to the execution of any trust (whether express, implied or constructive) to which any Note may be subject. The Company shall not (except as provided by statute or as ordered by a court of competent jurisdiction) be bound to enter any notice of any trust (whether express, implied or constructive) on the register in respect of any of the Notes.

The Notes are freely transferable in accordance with this Part 3 of Schedule 2 in integral multiples of £1 by instrument in writing in the usual common form (or in such other form as the Directors may approve) and such instrument need not be under seal. Additionally and, notwithstanding any other provision of this Instrument, for so long as the Subordination Agreement remains in force and effect, no transfer of the Notes may take place unless the transferee in respect of those Notes being transferred is either a party to the Subordination Agreement or has entered into a deed of adherence to be bound by the terms of such Subordination Agreement, or has otherwise entered into subordination arrangements with the Senior Lenders in writing or the requirement to enter into subordination arrangements with the Senior Lenders has been otherwise waived by the Senior Lenders in writing in advance of such intended transfer of the Notes; any attempt to transfer Notes in breach of the foregoing provisions is void ab initio.

2.	Each instrument of transfer shall be signed by the transferor, and the transferor shall be deemed to remain the owner of the Notes to be transferred until the name of the transferee is entered in the register in respect of such Notes.

Each instrument of transfer shall be sent to, or left for registration at, the registered office of the Company for the time being, and shall be accompanied by the Certificate(s) for the Notes to be transferred and any other evidence that the Company may require to prove the title of the transferor or his right to transfer the Notes (and, if such instrument is executed by some other person on his behalf, the authority of that person to do so). All instruments of transfer that are registered may be retained by the Company.

4.	No transfer of Notes shall be registered in respect of which a Redemption Notice, an Uplift Allocation Notice, a Pay Down Notice or Conversion Notice has been given.

5.	The Company undertakes that, while an aggregate principal amount of Notes greater than £10,000,000 remains in issue, it shall not, without prior Noteholder Majority Consent:

(a)

sell, transfer, lease, licence or otherwise dispose of any material asset or business of any Group Company (including the sale, transfer or other disposition of a Group Company’s rights to a third party), other than in the ordinary course of business;

(b)

carry out any merger, reorganisation, restructuring or sale of all or substantially all of the assets and/or business of any Group Company;

(c)

effect the liquidation, dissolution, or winding of any Group Company, or the cessation of all or substantially all of the business of any Group Company;

(d)

authorise any debt security (the incurrence, or extension of any credit or loan guarantee in respect of any loan or grant of credit exceeding £800,640.512(save that, for the avoidance of doubt, no Noteholder Majority Consent shall be required for (i) any refinancing, in whole or in part, of any Existing Indebtedness; or (ii) the subscription by any Qualifying Noteholder (and the issuance by the Company) for any Tranche 2 Notes pursuant to the Securities Purchase Agreement);

(e)

discontinue any existing line of business of any Group Company or enter into any new line of line of business by any Group Company; or

(f)

issue any securities senior to the Ordinary Shares with respect to voting rights, dividends, conversion rights, redemption rights, liquidation preference or otherwise.

Payment of the principal amount and all accrued interest on the Notes may be made by cheque made payable to, or by bank transfer to an account nominated for the purpose to the Company in writing by, the registered holder or, in the case of joint registered holders, to the one who is first-named on the register, or to such person or persons as the registered holder or all the joint registered holders may in writing direct and sent to the registered holder or in the case of joint registered holders to that one of the joint registered holders who is first-named on the register or to such address as the registered holder or joint registered holders may in writing direct. Cheques may be sent through the post at the risk of the registered holder or jointly registered holders and payment of any such cheque by the bankers on whom it is drawn, or a bank transfer to the relevant account, shall be good discharge to the Company.

If more than one person is entered in the register as joint holders of any Notes then, without prejudice to paragraph 5 of this Part 3 of Schedule 2, the receipt of any one of such holders for any moneys payable on or in respect of the Notes shall be as effective a discharge to the Company or other person making the payment as if the person signing such receipt were the sole registered holder of such Notes.

If any Certificate is worn out or defaced then, on production of it to the Directors, they may cancel it and may issue a fresh Certificate in lieu. If any Certificate is lost or destroyed it may be replaced on such terms (if any) as to evidence and indemnity as the Company may reasonably require. An entry recording the issue of the new Certificate and indemnity (if any) shall be made in the register. No fee shall be charged for the registration of any transfer or for the registration of any probate, letters of administration, certificate of marriage or death, power of attorney or other documents relating to or effecting title to any Notes.

Any notice or other document required to be given under this Instrument shall be in writing and may be given to or served on any Noteholder by sending it by first-class post in a prepaid envelope addressed to such Noteholder at his registered address. In the case of joint Noteholders, a notice given to, or document served on, the Noteholder whose name stands first in the register in respect of such Notes shall be sufficient notice to, or service on, all the joint holders. Any such notice sent or document served by first-class post shall be deemed to have been given or served 48 hours or 96 hours in the case of a notice or document sent to an address for a Noteholder not in the United Kingdom after the time when it is posted and in proving such notice or service, it shall be sufficient to prove that the envelope containing the notice or document was properly addressed, stamped and posted.

10.

Any notice or other document delivered or sent by post to, or left at, the registered address of any Noteholder in pursuance of these provisions shall, notwithstanding that such Noteholder is then dead or bankrupt or in liquidation, and whether or not the Company has notice of his death or bankruptcy or liquidation, be deemed to have been duly served or delivered in respect of any Notes registered in the name of such Noteholder as sole or first-named joint holder unless his name shall at the time of the service of the notice or document have been removed from the register as the holder of the Notes, and such service shall for all purposes be deemed sufficient service of such notice or document on all persons interested (whether jointly with or as claiming through or under him) in the Notes.

11.	A copy of this Instrument shall be kept at the Company’s registered office. A Noteholder (and any person authorised by a Noteholder) may inspect that copy of the Instrument at all reasonable times during office hours.

12.

Each Noteholder by subscribing for and/or holding any Notes pursuant to the terms of this Instrument expressly and irrevocably agrees that the Group Companies may refinance all or any part of either the Senior Loan or the Novartis Loan Note (either with the existing creditors thereof or with third party creditors) and that, such refinanced loan shall for all purposes under this Instrument be treated, mutatis mutandis¸ as the Senior Loan or the Novartis Loan Note (as the case may be) and benefit from any protections, provisions, exemptions or other terms hereof, without requiring the consent of any Noteholder; provided, that no such refinancing or amendment of the

Senior Loan which increases the amount of the principal sum of the Senior Loan owing from time to time above £14 million, or extends the Final Repayment Date for the Senior Loan beyond 1 March 2022, shall be effective unless otherwise approved by the Noteholder Majority; provided, further, that no such consent or agreement shall be required from any Noteholder Majority from or after the time when Shareholder Approval has been obtained. For the avoidance of doubt, if any such refinancing takes place, any lenders thereunder shall be treated as the “Senior Lenders” for the purposes of this Instrument. The Company shall as soon as reasonably practicable after the occurrence of any such refinancing, provide notice of the same to the Noteholders.

13.

If the Company, whilst any Notes are outstanding, shall effect a subdivision of its Ordinary Shares, the Tranche 1 Conversion Price and Tranche 2 Conversion Price (if any) then in effect immediately before that subdivision shall be proportionately decreased. If the Company, whilst any Notes are outstanding, shall combine its Ordinary Shares, the Tranche 1 Conversion Price and Tranche 2 Conversion Price then in effect immediately before the combination shall be proportionately increased.

14.

If the Company, whilst any Notes are outstanding, shall make or issue, or fix a record date for the determination of holders of its Ordinary Shares entitled to receive a dividend or other distribution to the shareholders from the fund for invested unrestricted equity payable in Ordinary Shares in the Company, then and in each such event the Tranche 1 Conversion Price and Tranche 2 Conversion Price then in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Tranche 1 Conversion Price or Tranche 2 Conversion Price, as applicable, then in effect by a fraction:

(a)

the numerator of which shall be the total number of Ordinary Shares outstanding immediately prior to the time of such issuance or the close of business on such record date, and

(b)

the denominator of which shall be the total number of Ordinary Shares outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of Ordinary Shares issuable in payment of such dividend or distribution;

provided, however, that if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Tranche 1 Conversion Price and Tranche 2 Conversion Price shall be recomputed accordingly as of the close of business on such date and thereafter the Tranche 1 Conversion Price and Tranche 2 Conversion Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions, if any.

15.

When any adjustment is required to be made in the Tranche 1 Conversion Price or Tranche 2 Conversion Price pursuant to paragraph 14 or 15, the number of Ordinary Shares issuable upon conversion of a Note shall be calculated by reference to the revised Tranche 1 Conversion Price or Tranche 2 Conversion price following the adjustment made by paragraph 14 or 15.

16.

If the Company, whilst any Notes are outstanding, shall: (i) pay or declare a dividend payable to all shareholders other than in Ordinary Shares (e.g. in cash or assets other than Ordinary Shares in the Company); or (ii) make any distribution of share capital (including share premium account and capital redemption legal reserve), then and in each such event the Tranche 1 Conversion Price and Tranche 2 Conversion Price then in effect immediately before such event shall be decreased as of such event by multiplying the Tranche 1 Conversion Price or Tranche 2 Conversion Price, as applicable, then in effect by a fraction:

(a)

the numerator of which shall be equal to (i) the Closing Price on the day immediately prior to the date when such event was first published (or if there is no such price, the fair market value of one ordinary share of the Company as of such date as determined in good faith by the Directors) minus (ii) the amount per issued share of such dividend or distribution; and

(b)

the denominator of which shall be the Closing Price on the day immediately prior to the date when such event was first published (or if there is no such price, the fair market value of one ordinary share of the Company as of such date as determined in good faith by the Directors).

In the event that the application of the above fraction would result in an increase in the Conversion Price, then no adjustment shall be made hereunder. If the Company distributes assets other than cash, the amount per outstanding share of the distribution shall be calculated by reference to the fair market value of the assets distributed as determined in good faith by the Directors.

“Closing Price” for purposes of this paragraph means: the most recently reported closing price of the Ordinary Shares on AIM.

17.

If, prior to the Maturity Date, there shall occur any reorganization, recapitalization, reclassification, consolidation, merger or demerger involving the Company in which the Company’s Ordinary Shares are converted into or exchanged for securities, cash or other property (other than a transaction covered by paragraphs 14 or 15) (collectively, a “Reorganization”), then, following such Reorganization, the Noteholders shall receive upon conversion the kind and amount of securities, cash or other property, if any, which the Noteholders would have been entitled to receive pursuant to such Reorganization if such conversion had taken place immediately prior to such Reorganization. Appropriate adjustment (as determined in good faith by the Directors) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Noteholder, to the end that the provisions set forth in this Instrument (including provisions with respect to changes in and other adjustments of the Tranche 1 Conversion Price and/or Tranche 2 Conversion Price (as applicable) and the number of Ordinary Shares issuable upon conversion of the Notes) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities, cash or other property thereafter deliverable upon the conversion of the Notes.

Schedule 3 Meetings of the Noteholders

The Company may at any time convene a meeting of Noteholders. In addition, the Company shall at the written request of the holders of not less than one-quarter (25%) in nominal amount of the outstanding Notes convene a meeting of the Noteholders. Any meeting shall be held at such place as the Company may designate.

At least 14 days’ notice (exclusive of the day on which the notice is served or deemed to be served and of the day for which notice is given) of every meeting shall be given to the Noteholders. The notice shall specify the place, day and time of the meeting and the general nature of the business to be transacted, but it shall not be necessary (except in the case of a Special Resolution) to specify in the notice the terms of any resolution to be proposed. The accidental omission to give notice to, or the non-receipt of notice by, any of the Noteholders shall not invalidate the proceedings at any meeting. A meeting of the Noteholders shall, despite being called at shorter notice than specified above, be deemed to have been duly called if it is agreed in writing by all of the Noteholders.

3.	At any meeting the quorum shall be two or more Noteholders holding, or representing by proxy, at least 50.1% in nominal principal amount of the outstanding Notes. No business (other than choosing a Chairman) shall be transacted at any meeting unless the requisite quorum is present.

If a quorum is not present, within half an hour from the time appointed for the meeting, the meeting shall be dissolved if it was convened on the requisition of Noteholders. In any other case, it shall stand adjourned to such day and time (at least 14 days later, but not more than 28 days later) and to such place as may be appointed by the Chairman. At such adjourned meeting, two Noteholders present in person (or by proxy) and entitled to vote shall constitute a quorum (whatever the nominal amount of the Notes held by them). At least 14 days’ notice of any adjourned meeting of Noteholders shall be given (in the same manner mutatis mutandis as for an original meeting). That notice shall state that two Noteholders present in person (or by proxy) at the adjourned meeting (whatever the nominal amount of Notes held by them) shall form a quorum.

A person (who may but need not be a Noteholder) nominated by the Company shall be entitled to take the chair at every such meeting but, if no such person is nominated or if the person nominated is not be present at the meeting within five minutes after the time appointed for holding the meeting, the Noteholders present shall choose one of their number to be Chairman. Any Director or officer of, any Secretary of, and the solicitors to, the Company and any other person authorised in that behalf by the Company may attend at any such meeting.

6.	Each question submitted to a meeting of Noteholders shall, unless a poll is demanded, be decided by a show of hands.

At any meeting of Noteholders unless a poll is demanded by the Chairman or by one or more Noteholders present in person or by proxy and holding or representing in the aggregate not less than one-twentieth in nominal amount of the outstanding Notes (before or on the declaration of the result of the show of hands), a declaration by the Chairman that a resolution has been carried by the requisite majority, lost or not carried by the requisite majority shall be conclusive evidence of the fact, without proof of the number or proportion of the votes recorded in favour of or against such resolution.

If a poll is duly demanded, it shall be taken in such manner and (subject as set out below) either at once or after an adjournment as the Chairman directs. The result of the poll shall be deemed to be the resolution of the meeting at which the poll was demanded. The demand for a poll shall not prevent the meeting from continuing for the transaction of any business other than the question on which the poll has been demanded. The demand for a poll may be withdrawn.

9.	If there is an equality of votes, whether on a show of hands or on a poll, the Chairman of the meeting shall not be entitled to a casting vote in addition to the vote(s) (if any) to which he may be entitled as a Noteholder or as a proxy.

10.

The Chairman may, with the consent of (and shall if so directed by) any meeting at which a quorum is present, adjourn the meeting from time to time and from place to place, but no business shall be transacted at any adjourned meeting except business that might lawfully have been transacted at the meeting from which the adjournment took place.

11.	Any poll demanded at any meeting on the election of a Chairman, or on any question of adjournment, shall be taken at the meeting without adjournment.

12.

On a show of hands, each Noteholder who is an individual and is present in person or (being a corporation) is present by its duly authorised representative or by one of its officers as its proxy, shall have one vote. On a poll, each Noteholder present in person or by proxy, shall have one vote for every £1 nominal principal amount of Notes held by him and a person entitled to more than one vote need not (if he votes) use all his votes or cast all the votes he uses in the same way.

13.

In the case of joint registered Noteholders any one of them shall be entitled to vote in respect of such Notes either in person or by proxy and, in the latter case, as if the joint holder were solely entitled to such Notes. If more than one joint holder is present at any meeting either personally or by proxy that one joint holder so present whose name as between himself and the other or others present stands first in the register as one of the joint holders shall alone be entitled to vote in person or by proxy.

14.

Each instrument appointing a proxy must be in writing and duly executed by the appointor or his duly authorised attorney or, in the case of a corporation under its common seal or duly executed by a duly authorised attorney or officer. The Chairman may (but shall not be bound to) require evidence of the authority of any attorney or officer. A proxy need not be a Noteholder.

15.	An instrument of proxy shall be in the usual or common form or in any other form that the Directors may accept. The proxy shall be deemed to include the right to demand or join in demanding a poll.

A proxy shall, unless stated otherwise, be valid as well for any adjournment of the meeting as for the meeting to which it relates and need not be witnessed.

16.

The instrument appointing a proxy, and the power of attorney or other authority (if any) under which it is signed or a notarially certified copy of such power of attorney or authority, shall be deposited at the place specified in (or in any document accompanying) the notice convening the meeting. If no such place is specified, the proxy shall be deposited at the registered office of the Company not less than 48 hours before the time appointed for holding the meeting or adjourned meeting or for taking of the poll at which the person named in that instrument proposes to vote. In default, the instrument of proxy shall not be treated as valid. A vote given in accordance with the terms of an instrument of proxy shall be valid notwithstanding the revocation of the proxy or of the authority under which the proxy is given, unless notification in writing of the revocation has been received at the registered office of the Company or at such other place (if any) specified for the deposit of instruments of proxy in the notice convening the meeting (or any document accompanying it) 48 hours before the commencement of the meeting or adjourned meeting or the taking of the poll at which the vote is given.

17.	Without prejudice to any of the powers conferred on the Company under any of the provisions of the Instrument, a meeting of the Noteholders shall, in addition to any other powers, have the following powers exercisable by Special Resolution:

(a)

power to sanction the exchange or sale of the Notes for, or the conversion of the Notes into, or the cancellation of the Notes in consideration of, shares, stock, debenture stock or other obligations or security of the Company or any other company formed or to be formed (provided, in each of the foregoing cases, that such action will be conducted in accordance with the terms of the Conditions or with the prior written consent of the Company);

(b)

power to sanction any abrogation, modification or compromise of, or any arrangement in respect of, the Noteholders’ rights against the Company, provided the same has been previously approved in writing by the Company, whether those rights shall arise under the Instrument, the Notes or otherwise;

(c)

power to assent to any modification of the provisions contained in the Instrument and the Conditions and to authorise the Company to execute any supplemental instrument embodying any such modification. Any such modification shall be proposed by the Company; and

(d)

with the prior written consent of the Company, power to:

(i)

modify the date fixed for final redemption of the Notes;

(ii)

reduce or cancel the principal amount payable on the Notes;

(iii)

reduce the amount payable or modify the method of calculating the amount payable on the Notes; or

(iv)

modify the dates for payment in respect of any interest, on the Notes.

18.

A Special Resolution passed at a meeting of the Noteholders shall be binding on all the Noteholders whether or not they are present at the meeting. Each of the Noteholders shall be bound to give effect to it accordingly. The passing of any such resolution shall be conclusive evidence that the circumstances justify passing it (so that the meeting may determine without appeal whether or not the circumstances justify passing it).

19.	Special Resolution, when used in the Conditions, means a resolution passed at a meeting of the Noteholders duly convened and held in accordance with the Conditions, and carried by a Noteholder Majority.

20.

A resolution in writing signed by or on behalf of a Noteholder Majority shall, for all purposes, be as valid and effectual as a Special Resolution passed at a meeting duly convened and held in accordance with the Conditions. Such resolution in writing may be contained in one document or in several documents in similar form, each signed by one or more Noteholders.

21.

Minutes of all resolutions and proceedings at every meeting shall be made and duly entered in books to be from time to time provided for that purpose by the Company. Any minutes, if purporting to be signed by the Chairman of the meeting or by the Chairman of the next succeeding meeting of the Noteholders, shall be conclusive evidence of the matters stated in them. Until the contrary is proved, every meeting for which minutes have been made and signed shall be deemed to have been duly held and convened, and all resolutions passed at the meeting to have been duly passed.

Terms and Conditions of the Warrants

1.	Terms and Conditions of the Warrants

1.1

Background and Reasons for Issuing the Warrants

The issuance of Warrants (as defined below) by Mereo BioPharma Group plc (the “Company”) is made pursuant to the terms and conditions set out herein (the “Terms and Conditions”).

In respect of the Offering (defined below), these Terms and Conditions will be appended to a securities purchase agreement dated June 3, 2020 (the “Securities Purchase Agreement”) between the Company and certain investors (the “Investors”) in an offering exempt from registration pursuant to Regulation D (the “Offering”) under the U.S. Securities Act of 1933, as amended (the “Securities Act”) under which the Investors have, subject to certain terms and conditions, undertaken to subscribe for the following securities of the Company: (a) units (the “Units”), with each Unit consisting of one ordinary share of the Company, nominal value £0.003 per share (such class of shares, the “Shares”), together with one warrant to subscribe for 0.50 Shares; and (b) one convertible promissory note in the original aggregate principal amount of £1 (all such convertible promissory notes to be issued to the Investors, the “Notes”), together with warrants to purchase a number of Shares equal to 0.5 times the number of Shares issuable upon conversion of each Note.

1.2

Number of Warrants

The Company shall issue warrants to the Investors entitling the holders thereof (the “Warrantholders”) conditional upon the receipt of the Shareholder Approval (as defined in the Securities Purchase Agreement) to subscribe for in aggregate a maximum of 161,048,366 Shares during the Share Subscription Period (as defined below) in accordance with Section 2, subject to adjustment as described in these Terms and Conditions (all such warrants to be issued to the Investors, the “Warrants”).

1.3

Subscription for Warrants

In accordance with the terms of the Offering, the Warrants have been subscribed for by, and shall be issued to, the Investors immediately following the execution of the Warrant Instrument.

The Warrants will be issued in certificated form in the form set out in Appendix (C) (each such certificate, a “Warrant Certificate”). The Company or its duly authorized agent shall maintain a register of the holders of Warrants, the Warrant Certificates they hold, and the number of Warrant Shares (defined below) for which their Warrants are exercisable.

The Company shall be entitled to treat each person named in the register of the holders of Warrants as a Warrantholder as the absolute owner of a Warrant and, accordingly, shall not, except as ordered by a court of competent jurisdiction or as required by law, be bound to recognise any equitable or other claim to or interest in a Warrant on the part of any other person, whether or not it shall have express or other notice of such a claim.

The Warrants will not be listed by the Company on a regulated market or other trading platform.

1.4

Transfer of Warrants

The Warrants shall not be transferred or pledged by a Warrantholder prior to August 8, 2020. Thereafter, the holder of any Warrants may freely transfer their Warrants, provided that such transfer of Warrants is made in compliance with these Terms and Conditions, applicable securities laws, and all requirements of regulatory authorities. The holder of the Warrant to be transferred or pledged must, prior to transfer or pledge of the Warrant, deliver to the Company: (a) the original Warrant Certificate (or an indemnity in a form satisfactory to the Company (acting reasonably) in the event that the Warrant Certificate is lost or destroyed); and (b) a duly executed Warrant Assignment in the form of Exhibit (A).

1.5

Prior to the Commencement Date

Notwithstanding that Sections 2.10 and 2.11 would apply to Warrants issued prior to the Commencement Date, those Sections shall not apply to any Warrants held by: (a) an Original Warrantholder (as defined in the Securities Purchase Agreement) who failed to attend (either in person or by proxy) any Shareholders Meeting called for the purpose of obtaining the Shareholder Approval and to vote in favour of such Shareholder Approval with the entirety of all voting rights available to such Original Warrantholder and (b) any person being a successor in title of, or claiming through or under, that Original Warrantholder.

1.6

Lapse

All Warrants shall lapse and no longer be outstanding upon the earliest of the Alternative Warrant Conversion Closing Date (as defined in the Securities Purchase Agreement) and the expiration of the Share Subscription Period and August 8, 2025, and rights of a holder with respect to the Warrant or the Warrant Shares issuable upon exercise thereof shall immediately terminate upon such lapse. Thereupon, all Warrant Certificates shall be deemed cancelled and will not in any circumstances be available for reissue or be valid for any purpose

2.	Terms and Conditions of Share Subscription

2.1

Right to Subscribe for Warrant Shares

Each Warrant Certificate entitles its holder conditional upon receipt of Shareholder Approval to subscribe for a number of new Shares set forth in the Warrant Certificate (the “Warrant Shares”), subject to adjustment as described in these Terms and Conditions. The Warrants may be exercised in whole or in part and, if in part, may be exercised from time to time during the Share Subscription Period.

If this Warrant shall have been exercised in part, the Company shall, at the request of the Warrantholder and upon surrender of this Warrant Certificate, at the time of delivery of the Warrant Shares, deliver to the Warrantholder a new Warrant evidencing the rights of the Warrantholder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

No fractional shares shall be issued upon the exercise of any Warrant. As to any fraction of a share which the Warrantholder would otherwise be entitled to purchase upon such exercise (determined on an aggregate basis with all other Warrants then being exercised by the Warrantholder), the Company shall round down to the next whole share.

2.2

Subscription Price

The subscription price for each Warrant Share is £0.348 (which price is expressed on a per-Share basis), subject to adjustment as described in these Terms and Conditions (the “Warrant Exercise Price”). The Warrant Exercise Price shall be booked in its entirety to the share capital (including to the extent relevant the share premium account) of the Company.

2.3

Share Subscription, Payment and Registration of Shares

Unless otherwise specifically provided under these Terms and Conditions, the Warrants shall be exercisable for the Warrant Shares as set forth in this Section 2.3 during the subscription period that commences on the Shareholder Approval Date (as defined in the Securities Purchase Agreement) (the “Commencement Date”), and ends on the third anniversary of the Commencement Date (the “Share Subscription Period”). Notwithstanding any other provision of these Terms and Conditions, prior to the Commencement Date, the Warrantholders shall not be able to exercise any right to subscribe for Warrant Shares and the Board of Directors of the Company will only have exercised any power to grant such right for the purposes of s551 Companies Xxx 0000 on the Commencement Date.

The Warrants may be exercised in whole or in part, at any time or from time to time on any Business Day (as defined in the Securities Purchase Agreement) during the Share Subscription Period, by surrender of the Warrant Certificate and the exercise notice in the form set out in Exhibit (C) (the “Exercise Notice”), duly completed and executed by the Warrantholder, to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Warrantholder at the address of the Warrantholder appearing on the books of the Company) specifying whether the Warrants will be exercised by way of:

(a)

cash payment, with the Warrantholder making payment to the Company in cash of the Warrant Exercise Price for the Warrant Shares (the “Exercise Amount”) by wire transfer of immediately available funds to the following account of the Company:

Account Name: Mereo BioPharma Group plc

Bank: [—]

Account No.: [—]

Sort Code: [—]

BIC/SWIFT: [—]

IBAN: [—]

(or such other account as the Company may from time to time notify the Warrantholder in replacement thereof) in an amount equal to the Exercise Amount; or

(b)

the cashless exercise procedure specified in Section 2.4 below,

together with in each case: (i) to the extent necessary under the Securities Act, delivery to the Company of an Accredited Investor Certification certifying the “accredited investor” status under the Securities Act of the recipient of the Warrant Shares to be received upon exercise of the Warrants in the form set out in Exhibit (B); and (ii) written certification from the Warrantholder that the exercise of the relevant Warrants will not result in the Warrantholder exceeding the exercise limitation provided for in Section 2.14, with such exercise to be effective upon receipt by the Company of such notice, such Exercise Amount and such Accredited Investor Certification (the “Effective Exercise”).

In the event the Warrantholder delivers an Accredited Investor Certification in connection with exercise of Warrants, unless there is then an effective registration statement covering the issuance or resale of the Warrant Shares to be issued upon exercise, the Warrant Shares shall bear the legend set forth in Section 2.13. If delivered to the Warrantholder via CREST, the Warrant Shares shall be issued free of any restrictive legends (with such Warrant Shares being eligible for trading on AIM, a market operated by London Stock Exchange plc (“AIM”) (if at the relevant time the Shares continue to be admitted to trading on AIM) and, if there is an effective registration statement covering the Warrant Shares to be issued upon exercise, then the Warrant Shares may be issued to the custodian of the Depositary (as defined in the Securities Purchase Agreement) and deposited with the Depositary, and, following such deposit the Company will direct the Depositary to issue an amount of ADSs (as defined in the Securities Purchase Agreement) via DTC (with such shares being eligible for listing on the Nasdaq Global Market or the Nasdaq Capital Market (“Nasdaq”) (in each case, as applicable).

Once received by the Company, an Exercise Notice shall be irrevocable save with the consent of the directors of the Company (or a duly authorised committee thereof). If the Company has reasonable grounds to object to any attempted exercise, it must give written notice of such objection within two (2) Business Days of receipt of the related Exercise Notice.

The Company shall issue Warrant Shares on the basis of the Warrants exercised in accordance with this Section 2.3, or resulting from the cashless exercise procedure pursuant to Section 2.4, to the exercising Warrantholder. Warrant Shares issued on the basis of Warrants exercised in accordance with this Section 2.3, or resulting from the cashless exercise procedure pursuant to Section 2.4, shall be: (i) written up in the Company’s register of members as soon as practicable (and in any event within 4 Business

Days) of the Effective Exercise, and if the applicable Exercise Notice requires the issue of share certificates, the applicable share certificates shall be issued to the relevant Warrantholders as soon as practicable (and in any event within 10 Business Days) of the issuance of the referable Warrant Shares; (ii) admitted to trading as set forth in Section 3.1; and (iii) if the applicable Exercise Notice requires delivery in uncertificated form, delivered to the relevant CREST account as set forth in Section 3.1.

Unless a relevant Exercise Notice is revoked or automatically cancelled in accordance with these Terms and Conditions, delivery of the Warrant Shares issuable upon exercise shall be made as soon as practicable (and in any event within 4 Business Days) after the Effective Exercise, provided that in the case of the cashless exercise procedure pursuant to Section 2.4 delivery of the Warrant Shares resulting therefrom shall be made as soon as practicable (and in any event within 4 Business Days) following receipt by the Company of the relevant Nominal Price (as defined in Section 2.4).

If by the close of the fourth Business Day period set out in the preceding paragraph, the Company fails (other than as a result of a failure within the CREST system) to deliver to the Warrantholder the required number of Warrant Shares to which the Warrantholder is entitled pursuant to the relevant exercise, and if after such 4 Business Day period and prior to the receipt of such Warrant Shares, the Warrantholder purchases (in an open market transaction or otherwise) Shares to deliver in satisfaction of a sale by the Warrantholder of the Warrant Shares which the Warrantholder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall, within 3 Business Days after the Warrantholder’s request promptly honor its obligation to deliver to the Warrantholder the Warrant Shares and pay cash to the Warrantholder in an amount equal to the excess (if any) of Warrantholder’s total purchase price (including brokerage commissions actually incurred, if any) for the Shares so purchased in the Buy-In over the product of (A) the number of Shares purchased in the Buy-In, multiplied by (B) the Closing Price (as defined above) of a Share on the date of Effective Exercise.

The Warrants shall be exercised and the Warrant Shares shall be issued subject to and in accordance with any applicable laws or regulations to which the Company is subject including the AIM Rules for Companies and the Market Abuse Regulation (EU 596/2014) and any other laws or regulations applicable in the jurisdiction in which the Warrantholder is located.

If, following delivery of Warrant Shares, the Warrantholder deposits those Warrant Shares with the Depositary for delivery of ADSs, the Company shall use its reasonable endeavours to cooperate with any reasonable request made of the Company by or on behalf of the Depositary in connection with such deposit and any sale of the ADSs under an effective registration statement covering such ADSs or pursuant to an exemption from registration available under the U.S. securities laws; provided, any ADSs (either certificates or book entry notations) shall be issued with restrictive legends under the Securities Act if, at the time of such deposit of the Warrant Shares, the ADSs have not then been registered for resale under that the Registration Rights Agreement (as defined in the Securities Purchase Agreement).

2.4

Cashless Exercise

In place of a subscription at full Warrant Exercise Price, a Warrantholder may, at its sole discretion, elect to exchange all or any portion of its Warrants by way of cashless exercise for such number of Warrant Shares calculated using the following formula:

where:

A =

the number of Warrant Shares to be issued to the Warrantholder;

B =

the number of Warrant Shares that would be issued to the Warrantholder in respect of the Warrants being exchanged if they were exercised at full Warrant Exercise Price rather than by way of cashless exercise;

C =

the Closing Price at the time of delivery of the Exercise Notice giving rise to the applicable cashless exercise; and

D =

the Warrant Exercise Price per Warrant Share, as adjusted hereunder.

Where the Warrantholder elects to exchange its Warrants by way of cashless exercise, the Warrantholder shall subscribe at nominal value for the Warrant Shares resulting from the above formula (the aggregate nominal value payable to the Company in respect of all such Warrant Shares being so subscribed shall be rounded up to the nearest £1 (the “Nominal Price”)).

The Company shall notify the Warrantholder of the Nominal Price and the Warrantholder covenants to pay the Nominal Price to the Company in cash in the manner set out in sub-paragraph (a) of Section 2.3 within 4 Business Days of such notification.

An issue of Warrant Shares to the Warrantholder pursuant to an election made in accordance with this Section 2.4 shall fully satisfy the Company’s obligations to issue Warrant Shares to such Warrantholder and, following such issue, the number of Warrant Shares for which that Warrantholder shall be entitled to subscribe shall be reduced by the number of Warrant Shares represented by the figure “B” in the formula above in respect of the relevant election.

If the Closing Price is less than the Warrant Exercise Price, and Exercise Notice shall be automatically cancelled.

The “Closing Price” means: (i) if at the relevant time the Shares continue to be admitted to trading on AIM, the most recently reported closing price of one Share on AIM; or (ii) if at the relevant time the Shares are no longer admitted to trading on AIM, the implied price of one Share in pounds sterling by reference to the most recently reported closing price of an ADS on Nasdaq. For the purposes of (ii), the closing price of an ADS shall be converted into pounds sterling in accordance with Section 3.5.

The provisions above permitting “cashless exercise” are intended, in part, to enable the parties to take the position that the exchange of this Warrant for Warrant Shares pursuant to such provisions will be characterized as and constitute a valid reorganization in the form of a recapitalization under section 368(a)(1)(E) of the U.S. Internal Revenue Code of 1986, as amended.

2.5

Shareholder Rights

The Warrant Shares subscribed for on the basis of the Warrants will rank for all dividends declared, made or paid after the date of issue and otherwise rank pari passu with the existing ordinary shares in the capital of the Company.

2.6

Adjustment for Subdivisions and Consolidations

If the Company, prior to the Shareholder Approval Date (as defined in the Securities Purchase Agreement), or following Shareholder Approval (as defined in the Securities Purchase Agreement) and prior to the end of the Share Subscription Period, shall effect a subdivision of its ordinary shares, the Warrant Exercise Price then in effect immediately before that subdivision shall be proportionately decreased and the number of shares issuable upon exercise of such Warrant shall be proportionately increased. If the Company, prior to the end of the Share Subscription Period shall consolidate its ordinary shares, the Warrant Exercise Price then in effect immediately before the combination shall be proportionately increased and the number of shares issuable upon exercise of such Warrant shall be proportionately decreased. Any adjustment under this Section 2.6 shall become effective at the close of business on the date the subdivision or consolidation becomes effective.

2.7

Adjustment for Certain Dividends and Distributions

If the Company, prior to the Shareholder Approval Date, or following Shareholder Approval and prior to the end of the Share Subscription Period, shall make or issue, or fix a record date for the determination of holders of its ordinary shares entitled to receive, a dividend or other distribution to the shareholders payable in ordinary shares in the Company, then and in each such event the Warrant Exercise Price then in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Warrant Exercise Price then in effect by a fraction:

(a)

the numerator of which shall be the total number of ordinary shares outstanding immediately prior to the time of such issuance or the close of business on such record date, and

(b)

the denominator of which shall be the total number of ordinary shares outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of ordinary shares issuable in payment of such dividend or distribution;

and the number of shares issuable upon exercise of such Warrant shall be multiplied by the inverse of such fraction; provided, however, that (i) if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Warrant Exercise Price and the number of issuable shares shall be recomputed accordingly as of the close of business on such date and thereafter the Warrant Exercise Price and the number of issuable shares shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions, if any; and (ii) no such distribution or dividend shall be made to the extent that the consequent adjustment under this Section 2.7 would be unlawful (including pursuant to s549 Companies Act 2006) and/or would be subject to pre-emption rights (including pursuant to s561 Companies Act 2006).

2.8

Adjustments for Other Dividends and Distributions

If the Company, prior to the Shareholder Approval Date, or following Shareholder Approval and prior to the end of the Share Subscription Period, shall: (i) pay or declare a dividend payable to all shareholders payable in cash or in specie out of profits available for distribution; or (ii) make any distribution or return of share capital (including share premium account and capital redemption reserve) to shareholders in cash or in-specie, then and in each such event the Warrant Exercise Price then in effect immediately before such event shall be decreased as of such event by multiplying the Warrant Exercise Price then in effect by a fraction:

(a)

the numerator of which shall be equal to (i) the Closing Price on the day immediately prior to the date when such event was first published (or if there is no such price, the fair market value of one ordinary share of the Company as of such date as determined in good faith by the Board of Directors) minus (ii) the amount per issued ordinary share of such dividend or distribution; and

(b)

In the event that the application of the above fraction would result in an increase in the Warrant Exercise Price, then no adjustment shall be made hereunder. If the Company distributes assets other than cash, the amount per outstanding share of the distribution shall be calculated by reference to the fair market value of the assets distributed as determined in good faith by the Board of Directors of the Company. No adjustment shall be made pursuant to this Section 2.8 where the relevant dividend or distribution falls within Section 2.7.

2.9

Adjustment for Reorganization

If, prior to the Shareholder Approval Date, or following Shareholder Approval and prior to the end of the Share Subscription Period, there shall occur any reorganization, recapitalization, reclassification, consolidation, merger or demerger involving the Company in which the Company’s ordinary shares are converted into or exchanged for securities, cash or other property (other than an event covered by Sections 2.6, 2.7, 2.8 or 2.10) (collectively, a “Reorganization”), then, following such Reorganization, the Warrantholder shall receive upon exercise of the Warrants the kind and amount of securities, cash or other property, if any, which the Warrantholder would have been entitled to receive pursuant to such Reorganization if such exercise had taken place immediately prior to such Reorganization. Appropriate adjustment (as determined in good faith by the Board of Directors) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Warrantholder, to the end that the provisions set forth in these Terms and Conditions (including provisions with respect to changes in and other adjustments of the Warrant Exercise Price and the number of Warrant Shares issuable upon exercise of the Warrants) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities, cash or other property thereafter deliverable upon the exercise of the applicable Warrants.

2.10

Treatment of Warrants in an Acquisition

In the event of an Acquisition prior to the Shareholder Approval Date, or following Shareholder Approval and prior to the end of the Share Subscription Period, the Company shall use its best efforts to ensure that lawful and adequate provision shall be made whereby each Warrantholder shall thereafter continue to have the right to purchase and receive upon the Terms and Conditions and in lieu of the Warrant Shares issuable upon exercise of the Warrants held by such Warrantholder (without regard to any limitations on exercise contained in such Warrants), shares of voting stock (the “Alternate Warrants”) in such successor, surviving or acquiring entity (as the case may be, the “Acquirer”), such that the aggregate value of the Warrantholder’s warrants to purchase such number of shares of the Acquirer (where the value of a warrant to purchase one share in the Acquirer is determined in accordance with the Black-Scholes Option Pricing formula set forth in Appendix (A) hereto, without regard to any limitations on exercise contained in such Warrants), is equivalent to the aggregate value of the Warrants held by such Warrantholder (where the value of each Warrant to purchase one Warrant Share is determined in accordance with the Black-Scholes Option Pricing formula set forth Appendix (B) hereto, without regard to any limitations on exercise contained in such Warrants). Furthermore, the Alternate Warrants shall have the same expiration date as the Warrants, and shall have a strike price, KAcq, that is calculated in accordance with Appendix (A) hereto. For the avoidance of doubt, if the Acquirer surviving or acquiring entity, as the case may be, is a member of a consolidated group for financial reporting purposes, the “Acquirer” shall be deemed to be the parent of such consolidated group for purposes of this Section 2.10 and Appendix (A) hereto.

(a)

Moreover, appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Warrant Exercise Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock thereafter deliverable upon the exercise of the Alternate Warrants. The Company shall use its best efforts to ensure that prior to or simultaneously with the consummation thereof the successor corporation resulting

from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume by written instrument, reasonably deemed by the Board of Directors of the Company and the Warrantholder to be satisfactory in form and substance, the obligation to deliver to the holder of the Warrants, at the last address of such holder appearing on the books of the Company, the Alternate Warrants to purchase such shares of stock of the Acquirer, as, in accordance with the foregoing provisions, such holder may be entitled to purchase, and otherwise assume the other obligations under these Warrants. The provisions of this Section 2.10 shall similarly apply to successive Acquisitions.

(b)

If the Company, in spite of using its best efforts, is unable to ensure that the Warrantholder shall have the Alternate Warrants until the expiration of the Share Subscription Period in connection with any Acquisition, then the Company (or the Acquirer) shall (to the extent lawful) pay the Warrantholder an amount equal to the Black-Scholes Value of this Warrant (where the value of each Warrant to purchase one Warrant Share is determined in accordance with the Black-Scholes Option Pricing formula set forth Appendix (B) hereto), unless the holders together of Warrants and Note Warrants representing at least two-thirds of the aggregate number of Warrant Shares issuable upon the exercise of all outstanding Warrants and of Shares issuable upon the exercise of all outstanding Note Warrants (in each case without regard to any limitations on exercise) (the “Majority Holders”) determine to waive such requirement to make such payment. Such payment shall be made in cash in the event that the Acquisition results in the shareholders of the Company receiving cash from the Acquirer at the closing of the transaction, and shall be made in shares of the Company (with the value of each share in the Company determined according to SCorp in Appendix (B) hereto) in the event that the Acquisition results in the shareholders of the Company receiving shares in the Acquirer or other entity at the closing of the transaction. In the event that the shareholders of the Company receive both cash and shares at the closing of the transaction, such payment to the Warrantholders shall (to the extent lawful) also be made in both cash and shares in the same proportion as the consideration received by the shareholders. Following any payment required pursuant to this Section 2.10(b), the Warrant shall terminate, without payment of any additional consideration therefor.

(c)

Notwithstanding anything to the contrary hereunder, if the Acquisition is (1) a transaction where the consideration paid to the holders of the Shares consists of cash, (2) a “Rule 13e-3 transaction” as defined in Rule 13e-3 under the Securities Exchange Act of 1934, as amended, (3) an Acquisition involving a person or entity not traded on a regulated market (within the meaning of the Markets in Financial Instruments Directive (2004/39(EC))) or a United States national securities exchange or (4) a transaction for which the Majority Holders reasonably determine that the Alternate Warrants proposed to be provided by the Acquirer do not satisfy the terms hereof (provided, that such holders consult with the Company and provide a written basis for such determination and that includes evidence of such determination by the Majority Holders), at the request of the Warrantholder

delivered before the ninetieth (90th) day after such Acquisition, the Company (or the Acquirer) shall (to the extent lawful) purchase this Warrant from the Warrantholder by paying to the Warrantholder, within five (5) Business Days after such request (or, if later, on the effective date of the Acquisition), cash in an amount equal to the Black-Scholes Value of this Warrant (where the value of each Warrant to purchase one Warrant Share is determined in accordance with the Black-Scholes Option Pricing formula set forth Appendix (B) hereto). Following any payment required pursuant to this Section 2.10(c), the Warrant shall terminate, without payment of any additional consideration therefor.

Notwithstanding the foregoing provisions of this Section 2.10, if Shareholder Approval has not then been received, this Section 2.10 shall not apply to any Acquisition occurring after August 8, 2023.

An “Acquisition” means any of the following: (i) any sale or similar transaction of all or substantially all of its assets in one or a series of related transactions; (ii) any merger, reorganization, consolidation, demerger or other similar transaction or a series of related transactions with or into another person in which the Company is not the survivor or the shareholders of the Company immediately before the transaction or series of related transactions own, directly or indirectly, less than a majority by voting power of the issued shares of the surviving or successor entity immediately after the transaction or series of related transactions; (iii) a scheme of arrangement under Part 26 of the Companies Act of 2006 pursuant to which all of the securities or shares in the Company become vested in a third party; (iv) a takeover offer within the meaning of Part 28 of the Companies Xxx 0000, or a public tender offer for the shares in the Company, pursuant to which a majority of its ordinary shares are acquired by a third party; or (v) the acquisition by any “person” or “group” (within the meaning of Section 13(d)(3) or 14(d)(2) of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”)), including any group acting for the purpose of acquiring, holding or disposing of securities (within the meaning of Rule 13d-5(b)(1) or any successor provision) directly or indirectly, of beneficial ownership (as such term is defined in Rule 13d-3 promulgated under the Exchange Act, or any successor provision) of outstanding shares of capital stock and/or other equity securities of the Company, in a single transaction or series of related transactions (including, without limitation, one or more tender offers or exchange offers), representing at least 50% of the voting power of the outstanding voting shares or economic interests in the then outstanding shares of capital stock of the Company.

2.11

Rights of Warrantholders in Certain Situations

(a)

If, prior to the end of the Share Subscription Period, an effective resolution for the winding up of the Company is passed, which is preceded by the making of a statutory declaration of solvency under s89 Insolvency Xxx 0000, for the purposes of ascertaining its rights in the winding up, be treated as if it had, immediately before the passing of the resolution, fully exercised its outstanding Warrants and shall be entitled to receive out of the assets available in the liquidation pari passu with the holders of the ordinary shares such sum as it would have received had it been the holder of all such ordinary shares to which it would have been entitled by virtue of that exercise after deducting a sum equal to the sum which would have been payable for Warrant Shares, but nothing in this Section 2.11 shall require the Warrantholder to make any payment to the Company or any other person.

(b)

Without duplication in respect of Section 2.9 or Section 2.10:

(i)

If, prior to the end of the Share Subscription Period, the Company makes a resolution to acquire its own shares through a tender offer to all the shareholders or to acquire other special rights entitling to shares issued in one or more transactions that were related to the offering of the Warrants (the “Related Offerings”) through a tender offer to all holders of such rights, the Company shall make an equal offer to the Warrantholders in respect of the Warrants. If the Company acquires its own shares in any other manner, or if the Company acquires stock options or special rights entitling to shares other than those issued in the Related Offerings, no measures will need to be taken in relation to the Warrants.

(ii)

If, prior to the end of the Share Subscription Period, a tender offer regarding all shares, stock options and other special rights issued by the Company is made by a party other than the Company, including pursuant to a scheme of arrangement under Part 26 of the Companies Xxx 0000, then the Warrantholders may transfer all of their Warrants to such offeror, as the case may be. If any such tender offer results in the third party acquiring a majority of the ordinary shares of the Company, then that event shall be deemed an “Acquisition” as set forth above.

The Board of Directors may at its discretion in any of the situations mentioned in this Section 2.11(b)(ii), also give the Warrantholders an opportunity (which for the avoidance of doubt shall not foreclose the Warrantholders from exercising the Warrants for the securities or other property for which they would otherwise have been exercisable) to exercise the Warrants or to convert the Warrants into equity issued by the offeror, as the case may be, on such terms and within such reasonable time period prior to the completion of the tender offer, as resolved by the Board of Directors.

Notwithstanding the foregoing provisions of this Section 2.11, if Shareholder Approval has not then been received, this Section 2.11 shall not apply to: (A) any winding up contemplated by Section 2.11(a), (B) any acquisition of own shares contemplated by Section 2.11(b)(i), or (C) any tender offer contemplated by Section 2.11(b)(i), in each case occurring after August 8, 2023.

2.12

Notice of Adjustment

To the extent reasonably practicable and not prohibited by law, not less than ten (10) Business Days prior to the record date or effective date, as the case may be, of: (i) any action which requires or might require an adjustment or readjustment of the Warrant Exercise Price or the number, amount or type of securities or other assets issuable upon

exercise of the Warrants; or (ii) an Acquisition, the Company shall give notice to the Warrantholder of such event, describing such event in reasonable detail and specifying the record date or effective date, as the case may be, and, with, if determinable, the required adjustment and computation thereof. If the required adjustment is not determinable as the time of such notice, the Company shall give notice to the Warrantholder of such adjustment and computation as soon as reasonably practicable after such adjustment becomes determinable.

2.13

Legend

Neither the Warrants nor the Warrant Shares issuable upon exercise of the Warrants have been or will be registered under the Securities Act or under any state securities laws of the United States, except as provided under the Registration Rights Agreement. Except as otherwise permitted by Section 2.3, each Warrant Certificate and each certificate representing the Warrant Shares shall bear the following legends or such variations thereof as the Company may prescribe from time to time:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) EXCEPT PURSUANT TO (A) AN EFFECTIVE REGISTRATION STATEMENT IN COMPLIANCE WITH THE SECURITIES ACT, (B) RULE 903 or 904 PURSUANT TO THE SECURITIES ACT, OR (C) RULE 144 UNDER THE SECURITIES ACT (UPON FURNISHING TO THE COMPANY SUCH REPRESENTATION LETTERS AS THE COMPANY MAY REQUIRE), OR (II) UNLESS AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO THE COMPANY, SHALL BE PROVIDED TO THE COMPANY, PROVIDING THAT SUCH SALE, TRANSFER OR ASSIGNMENT DOES NOT REQUIRE REGISTRATION UNDER THE SECURITIES ACT.

2.14

Exercise Limitation

Notwithstanding any provisions herein to the contrary, the Warrantholder shall not be entitled to exercise Warrants if, immediately prior to or after giving effect to such exercise, such Warrantholder beneficially owns 9.99% or more of the outstanding Shares, and the Warrantholder shall not be entitled to exercise Warrants for a number of Shares in excess of that number of Shares which, upon giving effect to such exercise, would cause the aggregate number of Shares deemed beneficially owned by the Warrantholder to exceed 9.99% of the outstanding Shares following such exercise. For purposes of the foregoing proviso, the aggregate number of Shares beneficially owned by the Warrantholder shall include the number of Shares issuable upon exercise of this Warrant with respect to which determination of such proviso is being made, but shall exclude the Shares which would be issuable upon (i) exercise of the remaining, unexercised Warrants beneficially owned by the Warrantholder and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by the Warrantholder subject to a limitation on conversion or exercise analogous to the limitation contained

herein. Except as set forth in the preceding sentence, for purposes of this Section 2.14, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. Notwithstanding the foregoing, the Warrantholder may increase or decrease the foregoing limitation to any other percentage, by written notice to the Company; provided, that the Warrantholder may not decrease the limitation prior to August 8, 2020; provided, further, that a request to increase such limitation requires not less than 61 days prior written notice (with such waiver of the foregoing limitation or request to increase such limitation taking effect only upon the expiration of such 61 day notice period and applying only to the Warrantholder and not to any other holder of Warrants) and that such limitation shall never be increased above 19.99%. For purposes of this Section 2.14, in determining the number of outstanding Shares, the Warrantholder may rely on the number of outstanding Shares as reflected in (x) the Company’s most recent periodic report filed with the SEC on the date thereof, (y) a more recent public announcement by the Company or (z) any other notice by the Company or its transfer agent setting forth the number of Shares outstanding. Upon the written request of the Warrantholder, the Company shall use commercially reasonable efforts to within confirm in writing or by electronic mail to the Warrantholder the number of Shares then outstanding within three (3) Business Days after written request by such Warrantholder. In any case, the number of outstanding Shares shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Warrantholder since the date as of which such number of outstanding Shares was reported.

2.15

Exercise Price Limitation

Notwithstanding anything to the contrary in these Terms and Conditions, no adjustment of the Warrant Exercise Price pursuant to any of Sections 2.6 to 2.9 shall result in the Warrant Exercise Price being less than the nominal value of a Warrant Share.

3.	Other Terms

All the provisions of the Articles of Association of the Company as to general meetings of the Company shall mutatis mutandis apply to any separate meeting of the Warrantholders as though the Warrants were a class of shares forming part of the Company and as if such provisions were expressly set out in extenso herein but so that:

The Initial Registration Statement shall be on F-1 or S-1 (or such shorter registration form as may then be available to the Company), as may then be applicable to the Company, and shall contain (except if otherwise required pursuant to written comments received from the Commission upon a review of such Registration Statement) the “Plan of Distribution” section in a form to be agreed by the parties promptly after Closing. Notwithstanding the registration obligations set forth in this Section 2, in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale on a continuous basis as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the Holders thereof and use its commercially reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission to permit offers and sales of the Registrable Securities pursuant to the Initial Registration Statement, or (ii) withdraw the Initial Registration Statement and file one or more new registration statements (together, the “New

Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on the applicable form; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with the SEC Guidance, including without limitation, the Compliance and Disclosure Interpretation 612.09 with respect to the Securities Act Rule 415, dated Jan. 26, 2009, compiled by the Commission’s Division of Corporation Finance. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation of the number of securities permitted to be registered on a particular Registration Statement as a secondary offering, unless otherwise directed in writing by a Holder as to its Registrable Securities, the number of securities to be registered on such Registration Statement will first be reduced by securities that are not Registrable Securities, and second by Registrable Securities represented by holders of Warrant Shares (applied, in the case that some Warrant Shares may be registered, to such Holders on a pro rata basis based on the number of unregistered Warrant Shares held by such Holders), and third by Registrable Securities represented by holders of Conversion Shares (applied, in the case that some Conversion Shares may be registered, to such Holders on a pro rata basis based on the number of unregistered Conversion Shares held by such Holders), and fourth by Registrable Securities represented by Shares (applied, in the case that some Shares may be registered, to such Holders on a pro rata basis based on the number of unregistered Shares held by such Holders), subject to a determination by the Commission that certain Holders must be reduced first based on the number of Shares, Conversion Shares and Warrant Shares held by such Holders In the event the Company amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on the applicable form (the “Remainder Registration Statements”).

(b) The Company shall use its commercially reasonable efforts to cause the Initial Registration Statement, any New Registration Statement and any Remainder Registration Statement to be declared effective by the Commission as soon as practicable and, with respect to the Initial Registration Statement or the New Registration Statement, as applicable, no later than the Effectiveness Deadline (including filing with the Commission a request for acceleration of effectiveness in accordance with Rule 461 promulgated under the Securities Act), and shall use its commercially reasonable efforts to keep each such Registration Statement continuously effective under the Securities Act until the earliest of (i) such time as all of the Registrable Securities covered by such Registration Statement have been sold by the Holders, (ii) the date that all Registrable Securities covered by such Registration Statement may be sold by non-affiliates without volume or manner-of-sale restrictions pursuant to Rule 144, as determined by counsel to the Company following discussions with the Company’s registrar (including pursuant to a written opinion letter to such effect, addressed and reasonably acceptable to the Company’s transfer agent, registrar or Depositary), and (iii) the third anniversary of the effectiveness thereof (the “Effectiveness Period”). The Company shall telephonically request effectiveness of a Registration Statement as of 5:00 P.M. New York City time on a Trading Day. The Company shall promptly notify the Holders via facsimile or electronic mail of a “.pdf” format data file of the effectiveness of such Registration Statement on or before the first Trading Day after the date that the Company telephonically confirms effectiveness with the Commission, which date of confirmation shall initially be the date requested for effectiveness of such Registration Statement. The Company shall, within two (2) Business Days after the Effective Date, file a final Prospectus with the Commission, as required by Rule 424(b).

(c) Each Holder agrees to furnish to the Company a completed Selling Shareholder Questionnaire not more than five (5) Trading Days following the date of this Agreement. At least ten (10) Trading Days prior to the first anticipated filing date of a Registration Statement for any registration under this Agreement, the Company will notify each Holder of the information the Company requires from that Holder other than the information contained in the Selling Shareholder Questionnaire, if any, which shall be completed and delivered to the Company promptly upon request and, in any event, no later than three (3) Trading Days prior to the applicable anticipated filing date. Each Holder further agrees that it shall not be entitled to be named as a selling securityholder in the Registration Statement or use the Prospectus for offers and resales of Registrable Securities at any time, unless such Holder has returned to the Company a completed and signed Selling Shareholder Questionnaire and a response to any requests for further information as described in the previous sentence at least three (3) Business Days prior to the applicable anticipated filing date. Each Holder acknowledges and agrees that the information in the Selling Shareholder Questionnaire or request for further information as described in this Section 2(c) will be used by the Company in the preparation of the Registration Statement and hereby consents to the inclusion of such information in the Registration Statement. Each Holder, by its acceptance of the Registrable Securities, shall cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement or amendment or supplement filed hereunder, unless such Holder has notified the Company in writing of such Holder’s election to exclude all of such Holder’s Registrable Securities from such Registration Statement.

(d) If: (i) the Initial Registration Statement is not filed with the Commission on or prior to the Filing Deadline (other than as a result of the objection of the Required Holders under Section 3(a) hereof that makes it impracticable for the Company to satisfy the Filing Deadline), (ii) the Initial Registration Statement or the New Registration Statement, as applicable, is not declared effective by the Commission (or otherwise does not become effective) for any reason on or prior to the Effectiveness Deadline, or (iii) after its Effective Date, (A) such Registration Statement ceases for any reason (including without limitation by reason of a stop order, or the Company’s failure to update the Registration Statement) to remain continuously effective as to all Registrable Securities included in such Registration Statement or (B) subject to Section 3(h), the Holders are not permitted to utilize the Prospectus therein to resell such Registrable Securities for any reason (other than due to a change in the “Plan of Distribution” or the inaccuracy of any information regarding any Holder holding no less than the majority of the Registrable Securities) in each case for more than an aggregate of thirty (30) consecutive calendar days or sixty (60) calendar days (which need not be consecutive days) during any twelve (12) month period (other than as a result of a breach of this Agreement by a Holder holding no less than the majority of the Registrable Securities or such Holder’s failure to return a Selling Stockholder Questionnaire within the time period provided by Section 2(d) hereof), or (iv) the Company fails to satisfy the current public information requirement pursuant to Rule 144(c)(1) as a result of which the Holders who are not affiliates are unable to sell Registrable Securities without restriction under Rule 144 (or any successor thereto), (any such failure or breach in clauses (i) through (iv) above being referred to as an “Event,” and, for purposes of clauses (i), (ii) or (iv), the date on which such Event occurs, or for purposes of

clause (iii), the date on which such thirty (30) or sixty (60) calendar day period is exceeded, being referred to as an “Event Date”), then in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the earlier of (1) the applicable Event is cured or (2) the Registrable Securities are eligible for resale pursuant to Rule 144 without manner of sale or volume restrictions, the Company shall pay to each Holder an amount in cash, as liquidated damages and not as a penalty (“Liquidated Damages”), equal to three percent (3.0%) of the aggregate purchase price paid by the original holder of such Shares and Notes pursuant to the Purchase Agreement, for any unregistered Registrable Securities then held by such Holder, which amount shall increase by one percent (1.0%) on the one-month anniversary of such Event Date that any such Event remains uncured; provided, that the parties agree that, notwithstanding anything to the contrary herein or in the Purchase Agreement, as applicable, no Liquidated Damages shall be payable with respect to any period after the expiration of the Effectiveness Period, and in no event shall the aggregate amount of Liquidated Damages payable to a Holder exceed, in the aggregate, five percent (5%) of the aggregate purchase price paid by the original holder of such Shares and Notes pursuant to the Purchase Agreement. The Liquidated Damages pursuant to the terms hereof shall apply on a daily pro rata basis for any portion of a month prior to the cure of an Event, except in the case of the first Event Date. The Company shall not be liable for Liquidated Damages under this Agreement as to any Registrable Securities which are not permitted by the Commission to be included in a Registration Statement due solely to SEC Guidance from the time that it is determined that such Registrable Securities are not permitted to be registered until such time as the provisions of this Agreement as to the Remainder Registration Statements required to be filed hereunder are triggered, in which case the provisions of this Section 2(d) shall once again apply, if applicable. In such case, the Liquidated Damages shall be calculated to only apply to the percentage of Registrable Securities which are permitted in accordance with SEC Guidance to be included in such Registration Statement. The Effectiveness Deadline for a Registration Statement shall be extended without default or Liquidated Damages hereunder in the event that the Company’s failure to obtain the effectiveness of the Registration Statement on a timely basis results from the failure of any Holder to timely provide the Company with information requested by the Company and necessary to complete the Registration Statement in accordance with the requirements of the Securities Act (in which case the Effectiveness Deadline would be extended with respect to Registrable Securities held by such Holder).

(e) “Piggy-Back” Registration. If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for shareholders other than the Holders) any of its Ordinary Shares or ADSs under the Securities Act in connection with the public offering in the United States of such securities solely for cash, other than (i) the initial registration under the Securities Act of any series or class of the Company’s securities, (ii) a registration under the Securities Act relating solely to the sale of securities to participants in an equity award plan, (iii) a registration under the Securities Act on Form F-4 or S-4, as may then be applicable to the Company (or any successor form), relating solely to a transaction pursuant to the SEC’s Rule 145 or (iv) a registration pursuant to the Existing Registration Rights Agreements, the Company shall, at such time, promptly give each Holder written notice of such registration. Upon the written request by a Holder given to the Company within ten (10) days after such notice by the Company, the Company shall, subject to the following paragraph, cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered

(each such registration, a “Piggyback Registration”) on such registration statement (each, a “Piggyback Registration Statement”). For the avoidance of doubt, and notwithstanding the foregoing, the Company shall have no such Piggyback Registration obligation to the extent that a depositary (other than the Depositary) for the Ordinary Shares files a registration statement on Form F-6 or other applicable form related to an unsponsored Level 3 American Depositary Receipt program.

In connection with any Piggyback Registration involving a primary sale of Ordinary Shares, the Company shall not be required to include any of the Holders’ securities in such underwriting unless such Holders accept the terms of the underwriting as agreed upon between the Company and the underwriters selected by it (or by other persons entitled to select the underwriters), and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company. If the total amount of securities, including Registrable Securities, requested by Holders to be included in such offering exceeds the amount of securities to be sold (other than by the Company) that the underwriters determine in their sole discretion is compatible with the success of the offering, then the Company shall be required to include in such offering only that number of such securities, including Registrable Securities, which the underwriters determine in their sole discretion will not jeopardize the success of the offering; provided, however, there shall first be excluded from such registration statement all Ordinary Shares sought to be included therein by any director, consultant, officer or employee of the Company or any subsidiary. If after such shares are excluded, the underwriters shall determine in their sole discretion that the number of securities which remain to be included in such offering exceeds the amount of securities to be sold that the underwriters determine is compatible with the success of the offering, then the Registrable Securities to be included, if any, shall be apportioned pro rata among the Holders providing notice of their desire to participate in the offering according to the total amount of securities entitled to be included therein owned by each selling Holder or in such other proportions as shall mutually be agreed to by such Holders.

No incidental right under this Section 2(e) shall be construed to limit any other registration required hereunder.

(f) Exchange of Ordinary Shares for ADSs. The Company shall use commercially reasonable efforts to ensure that the Registrable Securities held in the form of Ordinary Shares held by the Holders are able to be deposited from time to time with the Depositary, and to cause the Depositary to issue an equivalent number of ADSs to the Holders in exchange therefor upon deposit of such Ordinary Shares.

(g) ADS Registration. The Company shall use commercially reasonable efforts to ensure that Ordinary Shares constituting Registrable Securities then represented by ADSs are registered for sale under the Securities Act and that the class of ADSs is registered under the Exchange Act during the Effectiveness Period.

(b) Use commercially reasonable efforts to (i) prepare and file with the Commission such amendments (including post-effective amendments) and supplements, to each Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement continuously effective as to the applicable Registrable Securities for its Effectiveness Period; (ii) cause the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented or amended, to be filed pursuant to Rule 424; (iii) respond as promptly as reasonably practicable to any comments received from the Commission with respect to each Registration Statement or any amendment thereto and, as promptly as reasonably possible, provide the Holders or their Designated Purchaser Counsel true and complete copies of all correspondence from and to the Commission relating to such Registration Statement that pertains to the Holders as “Selling Shareholders” but not any comments that would result in the disclosure to the Holders of material and non-public information concerning the Company; and (iv) during the Effectiveness Period, comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a Registration Statement until such time as all of such Registrable Securities shall have been disposed of (subject to the terms of this Agreement) in accordance with the intended methods of disposition by the Holders thereof as set forth in such Registration Statement as so amended or in such Prospectus as so supplemented. In the case of amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 3(b)) by reason of the Company filing a report on Form 20-F or 10-K, Form 10-Q or Form 6-K or 8-K, in each case as may then be applicable to the Company, or any analogous report under the Exchange Act, the Company shall have incorporated such report by reference into such Registration Statement, if applicable, or shall file such amendments or supplements with the Commission promptly after the day on which the Exchange Act report that created the requirement for the Company to amend or supplement such Registration Statement was filed with the Commission.

(c) Notify the Holders and their Designated Purchaser Counsel (which notice shall, pursuant to clauses (iii) through (vi) hereof, be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as practicable via electronic mail (and, in the case of (i)(A) below, not less than two (2) Trading Days prior to such filing): (i)(A) when a Prospectus or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed; (B) when the Commission notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments in writing on any Registration Statement (in which case the Company shall provide to each of the Holders true and complete copies of all comments that pertain to the Holders as a “Selling Shareholder” or to the “Plan of Distribution” and all written responses thereto, but not information that the Company believes would constitute material and non-public information); and (C) with respect to each Registration Statement or any post-effective amendment, when the same has become effective; (ii) of any request by the Commission or any other Federal or state governmental authority for amendments or supplements to a Registration Statement or Prospectus or for additional information that pertains to the Holders as “Selling Shareholders” or the “Plan of Distribution”; (iii) of the issuance by the Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose; (iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such purpose; (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in such Registration Statement or Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to such Registration Statement, Prospectus or other documents so that, in the case of such Registration Statement or the Prospectus, as the case may be, it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they were made), not misleading, and (vi) of the occurrence or existence of any pending corporate development with respect to the Company that the Company believes may be material and that, in the determination of the Company, makes it not in the best interest of the Company to allow continued availability of a Registration Statement or Prospectus, provided that, the Company shall not disclose the content of such development or non-public information; and provided, further, the Company, by its use of the suspension under this clause (vi) makes no acknowledgement that any such information is material, non-public information.

(d) Use commercially reasonable efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as practicable.

(e) If requested by a Holder, furnish to such Holder, without charge, at least one conformed copy of each Registration Statement and each amendment thereto and all exhibits to the extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission; provided, that the Company shall have no obligation to provide any document pursuant to this clause that is available on the Commission’s XXXXX system.

(f) Prior to any resale of Registrable Securities by a Holder, use its commercially reasonable efforts to register or qualify or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the registration or qualification) of such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that the Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such jurisdiction.

(g) If requested by a Holder, cooperate with such Holder to facilitate the timely preparation and delivery of certificates (if such securities are then represented by certificates) or book entry statements representing Registrable Securities to be delivered to a transferee pursuant to the Registration Statement, which certificates or book entry statements, as the case may be, shall be free, to the extent permitted by the Purchase Agreement and under law, of all restrictive legends, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holders may reasonably request.

(h) Following the occurrence of any event contemplated by Section 3(c), the Company shall as promptly as practicable (but, in the case of Section 3(c)(vi), after taking into account the Company’s good faith assessment of any adverse consequences to the Company and its shareholders of the premature disclosure of such event) prepare a supplement or amendment, including a post-effective amendment, to the affected Registration Statements or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, form of prospectus or supplement thereto, in light of the circumstances under which they were made), not misleading. If the Company notifies the Holders in accordance with clauses (iii) through (vi) of Section 3(c) above to suspend the use of any Prospectus until the requisite changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled to exercise its right under this Section 3(h) to suspend the availability of a Registration Statement and Prospectus for a period not to exceed sixty (60) calendar days (which need not be consecutive days) in any twelve (12) month period without incurring liability for Liquidated Damages otherwise required pursuant to Section 2(d)(iii)(B).

(i) The Company may require each selling Holder to furnish to the Company a certified statement as to (i) the number of Ordinary Shares beneficially owned by such Holder and any Affiliate thereof, (ii) any Financial Industry Regulatory Authority (“FINRA”) affiliations, (iii) any natural persons who have the power to vote or dispose of the Ordinary Shares and (iv) any other information as may be requested by the Commission, FINRA or any state securities commission. During any periods that the Company is unable to meet its obligations hereunder with respect to the registration of Registrable Securities because any Holder holding no less than the majority of the Registrable Securities fails to furnish such information within three (3) Trading Days of the Company’s request, any Liquidated Damages that are accruing at such time as to such Holder only shall be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until such information is delivered to the Company.

(j) The Company shall cooperate with any registered broker through which a Holder proposes to resell its Registrable Securities in effecting a filing with FINRA pursuant to FINRA Rules 5110 and/or 5190 as requested by any such Holder and the Company shall pay the filing fee required for the first such filing promptly and in any case within the time period then required by FINRA.

The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without limitation, fees and expenses (A) with respect to filings required to be made with any Trading Market on which the Ordinary Shares are then listed for trading and with AIM, (B) with respect to compliance with applicable laws of the United Kingdom, state securities or Blue Sky laws (including, without limitation, fees and disbursements of counsel for the Company in connection with Blue Sky qualifications or exemptions of the Registrable Securities and determination of the eligibility of the Registrable Securities for investment under the laws of such jurisdictions as requested by the Holders) and (C) if not previously paid by the Company pursuant to Section 3(j) above, with respect to any filing that may be required to be made by any broker through which a Holder intends to make sales of Registrable Securities with FINRA pursuant to the FINRA Rules 5110 and/or 5190, so long as the broker is receiving no more than a customary brokerage commission in connection with such sale, (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities and of printing prospectuses if the printing of prospectuses is reasonably requested by the Holders of a majority of the Registrable Securities included in the Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, (vi) fees and expenses of any Depositary to the extent agreed between the Company and the Depositary (including those fees and charges in the circumstances contemplated by Section 2(f) on the basis that the parties acknowledge that the deposit of the Ordinary Shares and issuance of ADSs should be treated as a single transaction notwithstanding the intervening filing of the Resale Registration Statement), and (vii) fees and expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement. The Company shall also pay all expenses incurred in connection with each Piggyback Registration by each Holder, including all registration, filing and qualification fees, printers and accounting fees relating or apportionable thereto, and the fees and disbursements of one counsel for the selling Holders selected by them in each such offering, but excluding share transfer taxes, underwriting discounts and commissions relating to the Registrable Securities. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of

the Registrable Securities on any securities exchange as required hereunder. The Company shall be responsible for the documented legal fees and expenses of the Lead Purchaser in connection with any Registration Statement (including, for the avoidance of doubt, any amendments or supplements thereto), not to exceed $50,000 in the aggregate. In no event shall the Company be responsible for any underwriting, broker or similar fees or commissions or any out-of-pocket expenses of any Holder, except to the extent provided for in the foregoing sentence and otherwise provided for in the Transaction Documents.

5. Indemnification.

In the event any Registrable Securities are included in a Registration Statement under this Agreement:

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and hold harmless each Holder, the officers, directors, agents, partners, members, managers, shareholders, Affiliates and employees of each of them, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, partners, members, managers, shareholders, agents and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based solely upon (i) any untrue statement of a material fact contained in any Registration Statement, any Prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising solely out of or relating solely to any omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (ii) any violation or alleged violation by the Company of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (A) such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and approved in writing by such Holder expressly for use in the Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto, or (B) in the case of an occurrence of an event of the type specified in Section 3(c)(iii)-(vi), related to the use by a Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing in accordance with the notice provisions of this Agreement that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated and defined in Section 6(c) below, to the extent that following the receipt of the Advice the untrue statement or omission giving rise to such Loss would have been corrected or (C) to the extent that any such Losses arise out of the Holder’s (or any other indemnified Person’s) failure to send or give a copy of the Prospectus or supplement (as then amended or supplemented), if required, pursuant to Rule 172 under the Securities Act (or any successor rule) to the Persons asserting an untrue statement or alleged untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of Registrable Securities to such Person

if such statement or omission was corrected in such Prospectus or supplement. The Company shall notify the Holders promptly of the institution, threat or assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an Indemnified Party (as defined in Section 5(c)) and shall survive the transfer of the Registrable Securities by the Holders.

(b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors, officers, agents, shareholders, Affiliates and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, partners, members, managers, shareholders, agents or employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based solely upon any untrue statement of a material fact contained in any Registration Statement, any Prospectus, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising solely out of or relating solely to any omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading (i) to the extent that such untrue statements or omissions are based upon information regarding such Holder furnished in writing to the Company by such Holder expressly for use therein or (ii) to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use in a Registration Statement, such Prospectus or such form of Prospectus or in any amendment or supplement thereto or (iii) in the case of an occurrence of an event of the type specified in Section 3(c)(iii)-(vi), to the extent related to the use by such Holder of an outdated or defective Prospectus after the Company has notified such Holder in writing in accordance with the notice provisions of this Agreement that the Prospectus is outdated or defective and prior to the receipt by such Holder of the Advice contemplated in Section 6(c). In no event shall the liability of any selling Holder hereunder be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all reasonable and documented fees and expenses incurred in connection with defense thereof; provided, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party in its ability to defend the applicable action or proceeding.

An Indemnified Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such fees and expenses; (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3) the named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest exists if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the expense of the Indemnifying Party); provided, that the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys at any time for all Indemnified Parties. The Indemnifying Party shall not be liable for any settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld, delayed or conditioned. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

Subject to the terms of this Agreement, all fees and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section 5) shall be paid to the Indemnified Party, as incurred, within twenty (20) Trading Days of written notice thereof to the Indemnifying Party; provided, that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses applicable to such actions for which such Indemnified Party is finally judicially determined to not be entitled to indemnification hereunder). The failure to deliver written notice to the Indemnifying Party within a reasonable time of the commencement of any such action shall not relieve such Indemnifying Party of any liability to the Indemnified Party under this Section 5, except to the extent that the Indemnifying Party is materially and adversely prejudiced in its ability to defend such action.

(d) Contribution. If a claim for indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such Losses, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if the indemnification provided for in this Section 5 was available to such party in accordance with its terms.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 5(d), (A) no Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Holder from the sale of the Registrable Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (B) no contribution will be made under circumstances where the maker of such contribution would not have been required to indemnify the Indemnified Party under the fault standards set forth in this Section 5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

The indemnity and contribution agreements contained in this Section 5 are in addition to any liability that the Indemnifying Parties may have to the Indemnified Parties and are not in diminution or limitation of the indemnification provisions under the Purchase Agreement.

6. Miscellaneous.

(a) Remedies. In the event of a breach by the Company or by a Holder of any of its obligations under this Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement. The Company and each Holder agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agree that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b) Compliance. Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it (unless an exemption therefrom is available) in connection with sales of Registrable Securities pursuant to the Registration Statement and shall sell the Registrable Securities only in accordance with a method of distribution described in the Registration Statement.

(c) Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of a notice from the Company of the occurrence of any event of the kind described in Section 3(c)(iii)-(vi), such Holder will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised in writing (the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or amended) may be resumed. The Company will use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company may provide share transfer orders to enforce the provisions of this Section 6(c). The Company agrees and acknowledges that any periods during which the Holder is required to discontinue the disposition of the Registrable Securities hereunder shall be subject to the provisions of Section 2(d).

(e) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified or supplemented, or waived unless the same shall be in writing and signed by the Company and the Holders holding no less than two-thirds (2/3) of the then outstanding Registrable Securities, in which case such amendment, modification, supplement or waiver shall be binding on all Holders, provided that any party may give a waiver as to itself. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders and that does not directly or indirectly affect the rights of other Holders may be given by Holders of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the provisions of the immediately preceding sentence.

(f) Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be delivered as set forth in the Purchase Agreement.

(g) Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties and shall inure to the benefit of each Holder. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. The Company may not assign its rights (except by merger or in connection with another entity acquiring all or substantially all of the Company’s assets) or obligations hereunder without the prior written consent of the Required Holders. Each Holder may assign its respective rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement provided that (i) the Holder agrees in writing with the transferee or assignee to assign such rights and related obligations under this Agreement, and for the transferee or assignee to assume such obligations, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (ii) the Company is, within ten (10) Business Days after such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being transferred or assigned, (iii) at or before the time the Company received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein, and (iv) the transferee is an “accredited investor,” as that term is defined in Rule 501 of Regulation D.

(h) Execution and Counterparts. This Agreement may be executed in two or more counterparts, each of which when so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf’ format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf’ signature were the original thereof.

(i) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be determined in accordance with the provisions of the Purchase Agreement.

(j) Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided by law.

(k) Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their good faith reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable.

(l) Headings. The headings in this Agreement are for convenience only and shall not limit or otherwise affect the meaning hereof.

(m) Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under this Agreement are several and not joint with the obligations of any other Purchaser hereunder, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser hereunder. The decision of each Purchaser to purchase the Securities pursuant to the Transaction Documents has been made independently of each other Purchaser. Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to protect and enforce its rights, including, without limitation, the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. The Company acknowledges that each of the Purchasers has been provided with the same Registration Rights Agreement for the purpose of closing a transaction with multiple Purchasers and not because it was required or requested to do so by any Purchaser.
