11.1. The subject and modes of exploitation are summarized in Article 27.

Until the end of the EXPLOITATION PHASE, the COMPANY shall conduct operations within the territory of the Member States of the European Union, to the extent specified in Article 27.

11.2. During the exploitation of the RESULTS, the COMPANY is free to improve upon the results. These improvements, useful enhancements to exploitation as specified in Article 27, shall be deemed part of the RESULTS, with this agreement applying also to those improvements.

11.3. COMPANY shall notify the DIRECTION GÉNÉRALE of its decision to exploit or not to exploit the RESULTS:

- Within six months after the RESEARCH PHASE;

- In writing and with detailed explanation/justification.

If the COMPANY does not make a notification under the preceding paragraph, the company is presumed irrefutably to be exploiting the results.

Where the COMPANY began to exploit the RESULTS during the RESEARCH PHASE, it cannot take the decision not to exploit the RESULTS except by justifying so by a particularly adverse development of the economical, technical or legal environment compared to the situation when the first act of exploitation has been made.

11.4. If the COMPANY decides not to exploit the RESULTS, the COMPANY will:

- Transfer the rights on the RESULTS to the REGION or any entity assigned by the REGION;

- Refrain from any use, exploitation, sale or any concession of all or part of the RESULTS;

- Not to pursue on behalf of any third party the research in whole or in part on the topic set out in Article 20, during the seventy-two months following its decision not to exploit.

Upon becoming owner of rights by virtue of paragraph 1, the REGION is free to sell said rights to anyone.

11.5. In accordance with Articles 74 to 78 of the REGULATORY DECREE, the COMPANY that decides to exploit the results shall pay the fees specified in Article 28. It will pay each fee upon receipt from the Receiver General of the Walloon Region an "Invitation to pay," indicating the payment methods.

11.6. The COMPANY may decide not to exploit the RESULTS during the RESEARCH PHASE or within six months following the end of it.

The COMPANY is completely exempt from repayment of the GRANT if the following two conditions are met simultaneously:

1. it communicates the decision by registered mail to the DIRECTION GÉNÉRALE, outlining the failure of the project in terms of technical and commercial targets set out in Articles 19 and following.

2. it transfers to the REGION, or any entity designated by it, the real rights on the RESULTS.

If the two conditions referred to in paragraph 2 are not met, the COMPANY will reimburse the total GRANT received to the REGION, without interest.

11.7. The COMPANY that has decided to exploit the results may subsequently notify the DIRECTION GÉNÉRALE that it is abandoning them. In this case, Articles 11.4 and 11.8. apply.

11.8. During the exploitation of the RESULTS, the COMPANY may stop reimbursing the GRANT if the following two conditions are met:

1. it renounces the exploitation and informs the DIRECTION GÉNÉRALE in writing the reasons for its decision on objective grounds;

2. it transfers to the REGION, or any entity designated by it, real rights on the RESULTS.

All previous payments made by the COMPANY remain acquired by the REGION and COMPANY remains liable to repay amounts during the calendar year of the waiver. The exemption referred to in paragraph 1 shall take effect the following calendar year of the decision.

12. Favourable Outcome

12.1.1. In accordance with the procedures laid down in article 28 of the DECREE and 74 and 75 of the REGULATORY ORDER, during the EXPLOITATION PHASE, the COMPANY will make annual repayments to the REGION according to the scenario of a favourable outcome under Article 28.

12.1.2. The favourable outcome depends on the SALES of the PRODUCT, PROCESS or SERVICE, knowledge or know-how gained from conducting the RESEARCH, patents acquired during the research phase, market share, prototypes, pilots, inclusion in networks, the reputation acquired by the COMPANY because of the conduct of the RESEARCH.

All of these items constitute the scenario of a favourable outcome of the project.

12.2. The repayment of the GRANT is made in two parts, one referred to in Article 28.1. which is independent of SALES, the other referred to in Article 28.2. which is dependent on SALES.

12.3.1. The amount of reimbursement independent of SALES is determined in Article 28.1. It is due if at least one of the elements specified in Article 12.1.2. is encountered.

The decision by the COMPANY not to renounce to the exploitation of results is an irrefutable presumption of the existence of at least one of the elements specified in Article 12.1.2.

12.3.2. At the end of the first half of each calendar year and for the first time on 30 June of the year following the RESEARCH PHASE, the COMPANY will pay to the REGION the fee referred to in Article 28.1.

The amounts annually reimbursed contribute to the scenario of a favourable outcome.

12.3.3. The amount of reimbursement that depends on annual SALES is determined by the effective annual TURNOVER.

During the first quarter of each calendar year, and for the first time on 30 March of the calendar year following the year in which ends the RESEARCH PHASE, the COMPANY communicates to the REGION the SALES amount of the previous calendar year. If the COMPANY exploits the results before the end of the RESEARCH PHASE, the first SALES communication provided should include the SALES during the RESEARCH PHASE.

The COMPANY will pay to the REGION a royalty on SALES. It amounts to a percentage of SALES in the period concerned, as outlined in Article 28.2.

12.4.1. To determine the commercial success of the project, the REGION and the COMPANY will determine the estimated SALES made during the EXPLOITATION PHASE, with PRODUCTS, SERVICES or PROCESSES being part of said exploitation of RESULTS. This TURNOVER is referred to in Article 28.3.

12.4.2. At the end of the EXPLOITATION PHASE specified in Article 27, the scenario of a favourable outcome is assessed.

The part of reimbursement dependent upon SALES is reviewed with regards to cumulative turnover forecast for the EXPLOITATION PHASE referred to in Article 28.3.

Within three months following the end of the EXPLOITATION PHASE, the DIRECTION GÉNÉRALE will evaluate the adequacy of RESEARCH results in terms of SALES achieved during the EXPLOITATION PHASE as compared to cumulated SALES estimates for the EXPLOITATION PHASE referred to in section 28.3, and will determine the amount, excluding interest, to be repaid and will communicate this to the COMPANY.

If this amount was more than what the COMPANY has already paid, excluding interest, for the SALES-dependent repayments then the COMPANY pays the difference.

If the amount is less than what the COMPANY has already paid, excluding interest, for the SALES-dependent repayments, the Region pays the difference.

12.5. The COMPANY will generate the accounting items related to the RESEARCH and have them certified by an accountant or auditor.

The SALES figure for the RESEARCH is accounted in a separate line item in the COMPANY accounts.

In case of failure by the COMPANY to communicate its TURNOVER or elements of its accounts, the TURNOVER taken into account to calculate the amount of reimbursement is calculated on the basis of double the forecasted TURNOVER used for the scenario of favourable outcome.

12.6. When the amounts reimbursed to the REGION reach, including interest, twice the LIQUIDATED AMOUNT, the company is released from its obligations to the REGION except those relating to Articles 13, 14, 15 and 18.

12.7. The sums due under the scenarios of a favourable outcome are increased by a simple interest rate under Article 75 of the REGULATORY DECREE. This interest is calculated on full month basis, from the first day after of the end of the RESEARCH PHASE.

13. Obligation of secrecy/confidentiality

13.1. The RESULTS and all other documents, information, knowledge and know-how relating to the RESEARCH are secret only to the extent that the COMPANY states that they have this character. The parties undertake to maintain their character.

This obligation is that each party:

- Can only make the use of the information as authorized by this agreement;

- Can only disseminate the information to its staff as strictly necessary;

- Requires the same obligation of confidentiality of its employees, subcontractors and contractors.

13.2. The obligation of secrecy and the prohibition of use stipulated in article 13.1. shall not apply to information where the applicant provides proof that:

- It has already been published on the date of signing this agreement, or

- It was already in his possession at the same date, or

- It was communicated by a third party without any breach of secrecy or

- It has fallen into the public domain, unless it was due to the fault of any party, a member of their staff, a subcontractor or a partner.

These exceptions are of strict interpretation; they only extend to explicit data and not to scientific or technical developments, even implicit, obtained during the RESEARCH.

13.3. The COMPANY may proceed with publications or communications of a scientific or technical nature relating to the RESEARCH or the RESULTS. In each case, it should be reported in the first set of reports referred to in Article 5.2. following the publication or communication.

14. Publicity

14.1. Whenever the COMPANY makes a publication or a communication about the RESEARCH or the RESULTS:

- It should explicitly mention, in all media that the RESEARCH is or has been funded by the REGION;

- It should explicitly mention, in any oral presentation, that the RESEARCH is or has been funded by the REGION.

14.2. The COMPANY should affix in a visible way a sign at the entrance of the premises where it performs the research. It should also affix an identification sticker to be clearly visible on all equipment when the cost of acquisition is part of ELIGIBLE EXPENSES under the equipment cost section of the budget.

The REGION provides for free signs and stickers for identification.

15. Methods of control

15.1. The COMPANY will accept and facilitate the exercise by the REGION of administrative, technical and scientific controls, to verify the proper implementation of this agreement, in particular the use of the budget for the sole conduct of the RESEARCH and in compliance with the work plan and timetable, budget limits and exploitation of the RESULTS.

The COMPANY agrees and will facilitate the controls provided by the laws and regulations on accounting and public support.

15.2. To this end, the persons delegated by the REGION and empowered, under the Royal Decree of 26 April 1968 regulating the organisation and coordination of the provision and use of grants, to exercise the control referred by Articles 55 to 58 of the accountancy laws of the State, coordinated 17 July 1991, will have access to places where the activities are carried out relevant to the RESEARCH and exploitation of RESULTS.

These persons may access any documents, at any site or location of the COMPANY, to verify the correct implementation of this agreement.

The COMPANY may appoint a representative to accompany the delegates from the REGION.

15.3. Persons delegated by the REGION may be accompanied by experts. The COMPANY may deny access to experts if it can establish that they are employed by a competing entity.

The REGION should contractually require the experts to undertake not to disclose to third parties nor to use the information collected during these checks.

These obligations do not include information already in the public domain at the time of inspection, nor those becoming public after the inspection by no fault of the expert, or those that the expert proves he legitimately held at time of the inspection, nor that he subsequently received from a third party without it being in violation of any obligation of confidentiality.

16. Accounting

The COMPANY will record transactions relating to this agreement in its accounts.

17. Disclaimer

Special Stipulations

19. Definitions

Under this Articles 19 and following, the following means:

- "PRODUCT"

- any non-invasive serum test for diagnosis or monitoring of colorectal cancer

- a research kit measuring cell apoptosis

- a kit for measuring the acetylation / deacetylation of the histone

- any reagent part of the test here above mentioned;

- "SERVICE" means any study, analysis for a third party or the GUARANTOR that uses the PRODUCT;

- PATENT: WO 2005/019826 A1, 3 March 2005 entitled "Detection of Histone

Change in Cell-Free Nucleosomes"

- PRIMARY LICENCE: patent licence agreement, signed on 30 October 2007 between ValiRx (24 Greville Street, London EC1N 8SS) and Chroma Therapeutics Limited (92 Milton Park Abingdon, Oxfordshire OX14 4RY), the patent owner

20. Purpose of the RESEARCH

The RESEARCH envisions the development and clinical validation of a tool for screening / early diagnosis of colorectal cancer based on the nucleosomics technology.

This technology is to detect by use of specific antibodies nucleosomes released into the blood by cell apoptosis and where the cell of origin carries histone modifications (acetylation, methylation, phosphorylation, ...) themselves recognized by other antibodies (sandwich technique).

21. Work plan and timetable for implementation.

The RESEARCH will begin on April 1^st 2009 and ends on September 30^th 2011.

The work plan is as follows:

Phase 1 (18 months) Development and preclinical validation.

Step 1: Identification of one or more sources of blood samples from patients and healthy subjects (controls) for developing the test. The samples are mainly sought in biobanks (100 to 200 samples: healthy subjects, patients with inflammatory disease (Crohns disease, recto-colitis), neo-cancer patients, metastatic cancer patients, treated and / or operated cancer patients)

Step 2: Screening of systematic samples by Western blot to detect modifications in specific histones. This phase will allow the identification of modifications between healthy subjects and those with conditions such as inflammatory disease and cancer. A selection of specific modifications will be made at the end of the process.

Step 2a: In parallel to systematic screening, testing of marketed antibody or specific kits for the detection of histone modifications will be performed, for identification of potential components for the diagnostic kit.

Step 3: Development of antibodies specific for the detection of histone modifications identified in step 2.

Step 4: Development of prototype kit and test on 50 samples for technical validation. This is to verify that the test produces the expected result.

Step 5: Conduct a pilot phase for the kit "colon cancer" to validate. The aim will be to establish a correlation between in-vitro test, the other biological parameters (markers, CRP, etc..) and colonoscopy. The pilot study will be prospective, interventional, diagnostic, not therapeutic, for non-commercial use.

Step 6: Biostatistic and comparative diagnosis analysis. The results of the pilot study will be analysed on a biostatistical basis also to identify cohorts for clinical validation in Phase 2.

Phase 2 (12 months) clinical validation and CE marking.

Step 7: Multicentre study for clinical validation based on the stratified cohort derived from step 6. The study would cover approximately 300 patients through 4 to 5 clinical centres and seek to validate the test as a screening / early diagnosis of colon cancer.

Step 7bis: Process of CE Marking

Step 8: Biostatistic and comparative diagnosis analysis. The results of the clinical study will be analysed on a biostatistical basis. Expert analysis of test results in relation to the particular clinical diagnosis available for the patient.

Step 9: Final Report.

Hereinafter called the COMPANY,

AS THIRD PARTY

WHEREAS:

Chroma Therapeutics Limited, 92, Milton Park Abington, Oxfordshire OX14 4RY, UK is the owner of the patent WO 2005/019826 A1, 3 March 2005 entitled "Detection of Histone Modification in Cell-Free Nucleosomes

hereinafter called the PATENT.

The DONOR OF SUBLICENSE is the owner of a licence on the Patent by virtue of the contract concluded on 3 October 2007. This licence is hereinafter referred to as the PRIMARY LICENSE.

The COMPANY introduced to the REGION a request for a repayable grant hereinafter called the GRANT for a research project entitled "Diagnosis of colorectal cancer by nucleosomics.

To perform the project, the COMPANY should use elements that are the subject of the PRIMARY LICENSE and therefore of the PATENT.

Therefore the DONOR OF SUBLICENSE has granted an exclusive licence on the PRIMARY LICENSE by virtue of the contract signed on 18 January 2008. This licence is hereinafter called the SECONDARY LICENSE.

The legal, regulatory and contractual requirements applicable to the GRANT state, in essence, that the COMPANY will transfer, in a certain number of cases, the exclusive exploitation rights on the results of the funded research, to the REGION or any entity designated by it. This transfer takes place when the COMPANY:

- renounces the GRANT within the course of the research;

- decides not to exploit the results;

- decides not to pursue the exploitation of results,

is declared bankrupt or

been the subject of a corporate restructuring or a liquidation.

In such cases, the continued use of the results can only be considered if the entity to which the exploitation rights are transferred simultaneously enjoys the rights to the PATENT part of the SECONDARY LICENSE.

IN WITNESS WHEREOF, IT IS AGREED AS FOLLOWS:

In any case where, under legal, regulatory or contractual provisions of the GRANT, the COMPANY transfers to the REGION or any entity designated by it the exclusive exploitation rights on the results of research funded by the GRANT, the DONOR OF SUBLICENSE agrees to grant to the REGION or the entity referred to an exploitation license of the PATENT and the PRIMARY LICENSE, following modalities set forth below.

The DONOR OF SUBLICENSE declares that it is familiar with cases where the transfer referred to in paragraph 1 takes place.

The REGION alone negotiates and determines with any interested entity the global rules under which it sells or it grants rights to exploit the results.

The exploitation licence that the DONOR OF SUBLICENSE grants to the covered entity is exclusive and covers at least the rights stipulated in the SECONDARY LICENSE. Its financial compensation may not exceed that which is stipulated in the SECONDARY LICENSE unless otherwise approved by the REGION.

The SECONDARY LICENSE is made under the condition subsequent to the conclusion of the license referred to in points 1. and 2. above.

Should the DONOR OF SUBLICENSE plan to abandon the PRIMARY LICENSE, it shall inform the REGION and the COMPANY beforehand. Within 90 days after receipt of this information, the REGION can ask the DONOR OF SUBLICENSE that it transfers ownership of the PRIMARY LICENSE for free and in preference to any other candidate. Once the transfer is effective, the REGION shall bear the defense proceedings or maintaining the PRIMARY LICENSE.

The DONOR OF SUBLICENSE and the COMPANY will send all mail related to this agreement and with addressee being the REGION to Direction Générale Operatoinelle Économie, Emploi et Recherche du Service public de Wallonie, Place de Wallonie 1, bâtiment III à 5100 Jambes. Any change of address (REGION, DONOR OF SUBLICENSE, COMPANY) will be notified in writing to all parties to this contract.

In case of contradiction between this agreement and other provisions which bind the DONOR OF SUBLICENSE and the COMPANY, the provisions of this agreement shall prevail, even if these were made before.

This agreement is concluded under the suspensive condition that the REGION gives the GRANT to the company.

Chroma Therapeutics owner of the PATENT, has been informed of the existence of the SECONDARY LICENSE and of the legal, regulatory and contractual conditions of the GRANT as acknowledged by the attached letter.

10.

This agreement is governed by Belgian law. Any dispute concerning its interpretation or execution is of the jurisdiction of Namur.

Done in Namur, the 16 March 2010, in 7 copies, each party acknowledging having taken one.

LETTER OF CHROMA THERAPEUTICS LIMITED

18^th November 2009

Mr. M Charlier

Inspecteur Principal

DG06

SPW

Place des Celestines, 1

5000 Namur

BELGIUM

Dear Sirs

Chroma Therapeutics on October 3, 2007 entered on into a license agreement with ValiRx plc covering patent No. W02005/019826 A1 on the Detection of histone modifications in cell free nucleosomes, technology commonly referred to as Nucleosomics^TM.

We have been informed that on January 18, 2008 ValiRx plc entered into a sub license agreement with ValiBIO SA the fully controlled Belgium subsidiary of ValiRx pc for the exploitation of said patent in the field of oncology. We have also been informed that VAliBIO submitted a request for a funding in the form of a refundable grant to the DG06 of the Walloon Public Service (the Walloon Region) for the Development of a diagnostic test for colorectal cancer using Nucleosomics^TM.

We have also been informed that under the rules applicable to this funding that if ValiBIO choose not to exploit the results of that research whether by reason of the termination of the license, or for other reason, than the Walloon Region would want a License to the Patent so that it can exploit the results and products developed with its support for a Diagnostic test for colorectal cancer. The terms of this license would on the same terms and conditions that currently exist between Chroma and ValiRx and ValiBIO as sub licensee with respect to obligations and liabilities, but only for a Colorectal Cancer Diagnostic.

This letter is to confirm that Chroma Therapeutics is aware of this agreement and in the case that ValiBIO does not exploit the results of the research then Chroma Therapeutics will, upon notification of this by ValiRx plc, be willing in good faith to enter into a license with the Walloon Region so that the Walloon Region can exploit the results on terms substantially similar to those in the original license, in the field of a diagnostic Test for Colorectal cancer using Nucleosomics. Until such a license has been agreed the Walloon Region shall be entitled to continue to exploit the results in the field of a diagnostic Test for Colorectal cancer on the terms of the original license.

Yours faithfully
