(d) At Closing, Seller shall make a capital investment in C3BS in the amount of USD 4,000,000 (the Capital Increase Amount) by way of subscription of new shares in C3BS at an issue price per share equal to the average closing price of the C3BS share for the last 30 days preceding the Closing as published daily by Euronext Brussels (the Subscription Price), through a contribution in kind of the Contributed Shares. At or around 10.00 am CET on the same day, C3BS shall issue to Seller a total number of new ordinary shares in C3BS (the New Shares) equal to the Capital Increase Amount divided by the Subscription Price (the New Shares, and such issuance of the New Shares being referred as the Capital Increase). The Capital Increase shall take place by means of a decision of the board of directors of C3BS in the context of the authorized capital to be enacted by a notarial deed on the Closing Date, subject to the issue by C3BS’ statutory auditors of the opinion as provided in Section 6.1(f). The New Shares will be entitled to dividends for the entire financial year during which they are issued. For that purpose, Seller shall provide to C3BS at the latest on the day before the Closing Date a duly executed, original copy of a proxy to represent Seller for the purpose of the Capital Increase in order to subscribe for the New Shares, to the extent required.

2.2 Lock-up

Seller undertakes towards C3BS not to Transfer, undertake to Transfer or announce any intention to Transfer during the Lock Up Period, any of the New Shares, without C3BS’s express prior written consent, not unreasonably to be withheld. By exception to the above, Seller may, during the Lock-Up Period, Transfer all or part of the New Shares to one of its Affiliates, it being understood that, in that case:

6

(a) Seller will inform C3BS in advance of the contemplated Transfer and of the identity of the proposed transferee (the Transferee);

(b) Seller and the Transferee will comply with all applicable disclosure requirements to that effect; and

(c) If the Transferee holding the New Shares is about to cease to be an Affiliate of Seller, it shall without delay and prior to it so ceasing to be an Affiliate notify C3BS that such event will occur and shall transfer those New Shares to Seller or to another Affiliate of Seller.

2.3 Purchaser’s Buy-Out Option

Purchaser will have the right at any time and in its sole discretion to purchase all of Seller’s rights under this Agreement and the Ancillary Documents (collectively, the Rights) for a one-time payment to Seller, whereby all further financial obligations of Purchaser and of the Company towards Seller shall lapse in exchange for such one-time payment to Seller (the Buy-Out Option). If Purchaser notifies Seller in writing of its desire to exercise its Buy-Out Option, then the parties agree to promptly enter into good faith negotiations to determine the then-current fair market value of such Rights. Notwithstanding the foregoing, the Buy-Out Option is subject to mutual agreement between the parties with respect to the fair market value of such Rights and neither party is obligated to enter into any transaction related to such Rights, unless and until the parties have agreed upon the fair market value of such Rights.

8.3 Purchaser’s Agreement to Indemnify

From and after the Closing, Purchaser agrees to indemnify, defend and hold harmless Seller and its Affiliates and their respective officers, directors, employees and Representatives (each a Seller Indemnitee) from and against any and all Damages asserted against, resulting to, imposed upon or incurred by any Seller Indemnitee, that consist of, arise from or are attributable to a breach of any representation or warranty of Purchaser contained in Article 4 of this Agreement.

18

8.4 Procedures for Resolution and Payment of Claims for Indemnification

(a) Except as provided in Section 8.5, below, if a Person entitled to be indemnified under this Article 8 (the Indemnitee) shall incur any Damages or determine that it may incur any Damages, either pursuant to a claim or demand asserted against or sought to be collected from it by a third party (a Third Party Claim) or a claim or demand that does not involve a claim or demand being asserted against or sought to be collected from it by a third party and believes that it is entitled to be indemnified against such Damages by a party hereunder (the Indemnitor), such Indemnitee shall deliver to the Indemnitor a notice (an Indemnitee’s Notice) signed by the Indemnitee, specifying in reasonable detail the nature of such Claim and the amount estimated to be involved in each claim for Damages, which amounts may be reasonably modified from time to time by Indemnitee; provided that any failure to give such Indemnitee’s Notice will not waive any rights of the Indemnitee, except for a willful failure or to the extent that the rights of the Indemnitor are actually prejudiced.

(b) If a Third Party Claim is made against an Indemnitee, the Indemnitor shall be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof with counsel selected by the Indemnitor; provided, however, that such counsel is not reasonably objected to by the Indemnitee. Any Indemnitee shall have the right to employ separate legal counsel in any Third Party Claim and to participate in the defense thereto, but the fees and expenses of such counsel shall not be at the expense of the Indemnitor unless (i) the Indemnitor shall have failed, within 30 days after having received an Indemnitee Notice, to assume the defense of such Claim with counsel reasonably acceptable to the Indemnitee, (ii) the employment of such counsel has been specifically authorized by the Indemnitor or (iii) the named parties to any such action (including, without limitation, any impleaded parties) include both such Indemnitee and the Indemnitor and, in the reasonable judgment of the Indemnitee, joint representation of both would be inappropriate due to actual or potential differing interests, and in that event the reasonable fees and expense of such separate counsel shall be paid by the Indemnitor. Except as otherwise herein provided, the Indemnitor shall not be liable to indemnify an Indemnitee for any settlement of any such action or claim effected without the consent of the Indemnitor (which consent shall not be unreasonably withheld or delayed). If the Indemnitor assumes the defense of a Third Party Claim, the Indemnitee shall agree to any settlement, compromise or discharge of a Third Party Claim that the Indemnitor shall recommend and that by its terms obligates the Indemnitor to pay the full amount of the liability in connection with such claim.

19

(c) The Indemnitor shall provide the Indemnitee, or vice versa, as the case may be, with copies of all complaints, motions, answers and other pleadings filed or received in connection with any Third Party Claim promptly after filing or receipt thereof.

8.5 Limitation of Liability

(a) Notwithstanding anything to the contrary herein, in no event shall any indemnity pursuant to this Article 8 include any consequential or punitive damages unless and to the extent that such damages have been asserted against the Indemnitee in a Third Party Claim.

(b) Notwithstanding anything to the contrary herein, in no event shall Seller be liable under Section 8.2 for Damages to the extent they exceed the Purchase Price plus any additional amounts paid by OnCyte to Seller under Sections 4 of the Asset Purchase Agreement.

(c) Each of the parties further acknowledges and agrees that, should the Closing occur, its sole and exclusive remedy with respect to any and all claims relating to this Agreement, the Company and the Transaction (other than claims of, or causes of action arising from, fraud) shall be pursuant to the indemnification provisions set forth in this Article 8. In furtherance of the foregoing, Purchaser hereby waives, from and after the Closing, any and all rights, claims and causes of action it, the Company or any Affiliate may have against Seller and its Affiliates arising under or based on any Federal, state or local Law or otherwise (except pursuant to this Article 8). For the avoidance of doubt, this Article 8 shall not apply to any claims relating to any Ancillary Documents.

8.6 Treatment of Indemnification Payments

Any payment made pursuant to the indemnification obligations under this Article 8 shall be treated as an adjustment to the Purchase Price.

9. PROTECTIVE COVENANTS

9.1 Right of First Negotiation

(a) Seller covenants with Purchaser and the Company that it will provide written notice to the Company of its intention to outlicense, sublicense or sell technology to develop or commercialize CAR-T Cell products for the treatment of cancer identified after the Effective Date of this Agreement and not subject to an agreement with a third party as of the Effective Date, to a third party (Third Party Transaction). During the 60-day period following such written notice from Seller, the Company will have the first right to negotiate the purchase of, or an exclusive license or sublicense to, the assets that are the subject matter of the proposed Third Party Transaction upon commercially reasonable terms mutually

20

acceptable to the parties. In the event that the Company intends not to exercise such right, it will provide Seller prompt written notice of its intention not to do so. If (i) the parties are unable to reach agreement in principle, through a non-binding term sheet or memorandum of understanding, on the material terms of such purchase or license within such 60-day period, (ii) the parties have reached agreement in principle, through a non-binding term sheet or memorandum of understanding, on the terms of such purchase or license within such 60-day period, but the parties are unable to enter into a definitive agreement within six months following the written notice from Seller, or (iii) the Company expresses in writing that it does not wish to enter into or continue negotiations, then Seller will have no further obligation to the Company and may enter into negotiations with third parties concerning the Third Party Transaction. If, however, the Company had submitted a written term sheet to Seller during the 60-day period following the written notice from Seller, but the parties were unable to enter into a definitive agreement within six months following the written notice from Seller, then Seller will not enter into a Third Party Transaction with respect to such technology on terms materially less favorable to Seller than the terms submitted by the Company in its term sheet submitted to Seller.

9.2 Non-Solicitation

(a) Seller covenants with Purchaser and the Company that it shall not and shall procure that none of its Affiliates shall:

(i) for a period of three years from Closing, induce or attempt to induce any person who is at Closing a supplier of goods or services to the Company to cease to supply, or to restrict or vary the terms of supply, to the Company; or

(ii) for a period of three years from Closing, do or say anything which is harmful to the reputation of the Company or which may lead a person to cease to deal with the Company on substantially equivalent terms to those previously offered or at all.

(b) Each of Purchaser and the Company covenants with Seller that it shall not and shall procure that none of its Affiliates shall:

(i) for a period of three years from Closing:

(A) induce or attempt to induce any person who is at Closing a director or employee of the Company to leave the employment of Seller; or

(B) employ or attempt to employ any person who is at Closing a director or employee of Seller; or

21

(ii) for a period of three years from Closing, induce or attempt to induce any person who is at Closing a supplier of goods or services to Seller to cease to supply, or to restrict or vary the terms of supply, to Seller; or

(iii) for a period of three years from Closing, do or say anything which is harmful to the reputation of Seller or which may lead a person to cease to deal with Seller on substantially equivalent terms to those previously offered or at all.

10.2 Assignment; Binding Effect; No Third-Party Rights

Except as otherwise provided in this Agreement, neither this Agreement nor the rights granted hereunder may be assigned or transferred by Seller or Purchaser (which consent will not be unreasonably withheld); provided, however, that a party may assign this Agreement and its rights and obligations hereunder without the other parties’ consent to any Affiliate. Notwithstanding the foregoing, any such assignment to an Affiliate will not relieve the assigning party of its responsibilities for performance of its obligations under this Agreement will. Any attempted assignment, delegation or transfer in violation hereof, shall be void and of no force and effect. Except as expressly stated in this Agreement, this Agreement is for the sole benefit of the parties hereto and is not intended to and shall not confer upon any Person other than the parties hereto any rights or remedies hereunder. Except as otherwise provided in this Agreement, this Agreement shall be binding on the permitted successors and assigns of the parties, each such permitted successor and assign being deemed to be a party hereunder in substitution of its respective transferor.

All expenses incurred by a party or on its behalf in connection with this Agreement or related to the preparation, negotiation, execution and performance of this Agreement, shall be borne by the party incurring such expenses.

10.5 Waivers; Amendments

Any waiver by any party of a breach of any provision of this Agreement shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Agreement. The failure of a party to insist upon strict adherence to any term of this Agreement on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. Any waiver must be in a writing signed by the waiving party. This Agreement may only be amended with the written consent of Seller and Purchaser.

10.6 Reformation and Severability

Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable Law, but if any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future Laws effective during the term hereof, then (i) in lieu of such illegal, invalid or unenforceable provision, the parties shall endeavor in good faith negotiations to agree on a provision as similar to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable, provided that no party shall be required to agree to any

23

provision that would materially alter any of its rights or obligations under this Agreement and (ii) the legality, validity and enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby except where the fundamental relationship among the parties has been materially altered.

10.7 Governing Law

This Agreement shall in all respects be governed by and construed in accordance with the Laws of the state of Delaware, including all matters of construction, validity and performance, in each case without reference to any conflict of law rules that might lead to the application of the Laws of any other jurisdiction. Each party to this Agreement further agrees that the Laws of the state of Delaware bear a reasonable relationship to this Agreement and irrevocably and unconditionally waives any objection to the application of the Laws of the state of Delaware to any dispute and further irrevocably and unconditionally waives and agrees not to plead or claim that any dispute should not be governed by the Laws of the state of Delaware.

10.8 Arbitration

In the event of any dispute, controversy or claim after the Closing among any of the parties hereto arising out of or relating to this Agreement, the parties shall attempt to resolve such dispute between themselves within thirty (30) calendar days following the date either party sends written notice of such dispute to the other party. If the parties fail to resolve such dispute within such period of time, then the dispute shall be finally settled by binding arbitration under the then-current Rules of Arbitration of the International Chamber of Commerce (the Rules). The dispute will be resolved before a panel of three experts with relevant industry experience (the Arbitral Tribunal). One arbitrator will be chosen by Seller and one arbitrator will be chosen by Company within fifteen (15) days from the notice of initiation of arbitration. The third arbitrator will be chosen by mutual agreement of the arbitrator chosen by Seller and the arbitrator chosen by Company within fifteen (15) days of the date the last arbitrator was appointed or, failing such agreement, will be appointed in accordance with the Rules. The place of the arbitration shall be New York, New York. The arbitration shall be conducted in the English language. The parties shall request the Arbitral Tribunal to use commercially reasonable efforts to rule on each disputed issue within thirty (30) calendar days after the completion of hearings; provided, however, that the failure of the Arbitral Tribunal to so rule during such period shall not affect or impair the validity of any arbitration award. The determination of the Arbitral Tribunal as to the resolution of any dispute shall be final, binding and conclusive upon all parties hereto. All rulings of the Arbitral Tribunal shall be in writing, describing the essential findings and conclusions on which an award is based, including the calculation of any damages awarded, and shall be delivered to the parties hereto. Any award rendered by the Arbitral Tribunal shall be enforceable in any court of competent jurisdiction.

24

10.9 Consent to Jurisdiction

Any litigation against any party to this Agreement (including, for avoidance of doubt, the Company) arising out of or in any way relating to this Agreement shall be brought in the Court of Chancery of the State of Delaware or in any federal court located in the State of Delaware and each of the parties hereby submits to the exclusive jurisdictions of such courts for the purpose of any such litigation. Each party further agrees that service of any process, summons, notice or document by U.S. registered mail to such party’s respective address set forth above shall be effective service of process for any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction in this Section 10.9. EACH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY OBJECTION TO THE LAYING OF VENUE OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF THE TRANSACTION IN THE COURT OF CHANCERY OF THE STATE OF DELAWARE OR IN ANY FEDERAL COURT LOCATED IN THE STATE OF DELAWARE AND HEREBY AND THEREBY FURTHER IRREVOCABLY AND UNCONDITIONALLY WAIVES AND AGREES NOT TO PLEAD OR CLAIM IN ANY SUCH COURT THAT ANY SUCH ACTION, SUIT OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

10.10  Waiver of Jury Trial

EACH PARTY HEREBY WAIVES TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT TO ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THE TRANSACTION.

10.11  Attorney’s Fees

25

10.12  Counterparts

This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
