shares of the Employers common stock and up to 5,000 Restricted Shares. To the extent the Employer cannot issue such securities pursuant to its stock incentive plans due to the fact that such plans have not reserved sufficient shares, any such
grant shall be deferred until the Employer has adopted an incentive plan that will enable such grants. Notwithstanding the foregoing, however, should the Executives employment terminate for any reason prior to the adoption of an eligible stock
incentive plan, the Employer shall be under no obligation to issue such defined options to the Executive. Any such incentive plans must receive shareholder approval in accordance with Nasdaq Capital Market continued listing standards.

The Employer shall grant the ISOs, if any, to the Executive within ninety (90) days following
the completion of the Employers fiscal year end. Except as noted in Section 6(f) hereof, one third of the ISOs granted, if any, shall vest on the date that is the first anniversary of the date of grant; one third of the ISOs granted shall
vest on the date that is the second anniversary of the date of grant; and one third of the ISOs granted shall vest on the date that is the third anniversary of the date of grant. Each of the ISOs so granted will have a ten year term and a strike
price equal to the fair market value of one share of the Employers common stock on the date of grant.

(ii) Restricted Stock.To the extent the Employers financial performance for any calendar year meets the Minimum Threshold, the Employer shall issue to the Executive 2,5000 shares of Restricted Stock. To the extent the Employers financial

performance for any calendar year meets or exceeds the Maximum Threshold, the Employer shall issue to the Executive an aggregate of 5,000 shares of
Restricted Stock. To the extent the Employers financial performance for any calendar year falls between the Minimum Threshold and the Maximum Threshold, the Employer shall issue to the Executive that number of shares of Restricted Stock

given calendar year by (ii) the Maximum Threshold less the Minimum Threshold; and

The Employer shall issue the shares of Restricted Stock, if any, to the Executive within ninety
(90) days following the completion of the Employers fiscal year end. The terms of the Restricted Stock shall provide that the Executive shall be unable to transfer such shares until they have vested. Except as noted in Section 6(f)
hereof, one third of the Restricted Shares issued, if any, shall vest on the date that is the first anniversary of the date of issuance; one third of the Restricted Shares issued shall vest on the date that is the second anniversary of the date of
issuance; and one third of the Restricted Shares issued shall vest on the date that is the third anniversary of the date of issuance. The Executive shall forfeit any unvested shares upon either (i) the termination of the Executives
employment by the Executive without Good Reason (as such term is defined herein) or (ii) the termination of the Executives employment by the Employer for Cause (as such term is defined herein).

(e) Regular Benefits. The Executive shall also be entitled to participate in any and all employee benefit plans, medical insurance plans, life
insurance plans, disability income plans, retirement plans, bonus incentive plans and other benefit plans from time to time in effect for senior executives of the Employer. Such participation shall be subject to (i) the terms of the applicable
plan documents, (ii) generally applicable policies of the Employer and (iii) the discretion of the Board of Directors of the Employer or any administrative or other committee provided for in or contemplated by such plan.

Board of Directors of the Employer, devote his full business time, best efforts and business judgment, skill and knowledge to the advancement of the Employers interests and to the discharge of his duties and responsibilities hereunder. He
shall not engage in any other business activity, except as may be approved by the Board of Directors; provided, however, that this Section 5 shall not be construed as preventing the Executive from:

(a) investing his assets in a manner not prohibited by Section 8(a) hereof, and in such form or manner as shall not require any material services on
his part in the operations or affairs of the companies or other entities in which such investments are made;

(b) serving on the board of
directors of any company, subject to the prohibitions set forth in section 8(a), to the extent that such service does not impair his ability to fulfill his duties and responsibilities under this Agreement; or

responsibilities under this Agreement.

Section 3, the Executives employment hereunder shall be subject to the following provisions:

(a) Death. In the event of
the Executives death during the Executives employment hereunder, the Executives employment shall terminate on the date of his death; provided, however, that the Employer shall continue to pay an amount equal to the Executives
salary to the Executives beneficiary designated in writing to the Employer prior to his death (or to his estate, if he fails to make such designation) for a period of one month after the date of the Executives death, at the salary rate
in effect on the date of his death, said payments to be made on the same periodic dates as salary payments would have been made to the Executive had he not died. The Employer shall also pay to the Executives beneficiary or estate the bonus
solely with respect to that portion of the Employers fiscal year completed on or before the date of death.

(b) Termination by the
Employer for Cause. The Executives employment hereunder may be terminated without further liability on the part of the Employer effective immediately by a two-thirds vote of the Board of Directors of the Employer for Cause by written

(i) gross incompetence, gross negligence, willful misconduct in office or breach of a material fiduciary duty owed to the Employer or any subsidiary or affiliate thereof;



5



---

(ii) conviction of a felony, a crime of moral turpitude or commission of an act of embezzlement or fraud
against the Employer or any subsidiary or affiliate thereof;

(iii) any material breach by the Executive of a material term of this
Agreement, including without limitation material failure to perform a substantial portion of his duties and responsibilities hereunder; or

(iv) deliberate dishonesty of the Executive with respect to the Employer or any subsidiary or affiliate thereof.

(c)
Termination by the Executive. The Executive may terminate his employment hereunder with or without Good Reason (as defined below) and he shall not be required to render any further services to the Employer. In the event of termination with
Good Reason, the Executive shall give written notice of the event or circumstances constituting Good Reason to the Board of Directors of the Employer. If such event or circumstances shall remain unremedied for a period of 30 days after receipt of
such notice by the Board of Directors, the Executive may then terminate his employment hereunder for Good Reason by written notice effective immediately. In the event of termination for Good Reason, the Executive shall be entitled to the benefits
specified in Section 6(e). Upon termination of employment by the Executive without Good Reason, the Executive shall be entitled to no further compensation or benefits under this Agreement. Good Reason shall be the material breach by
the Employer of any material provision of this Agreement.

(d) Termination by the Employer Without Cause. The Executives
employment with the Employer may be terminated without Cause by a two-thirds vote of the Board of Directors of the Employer effective immediately by written notice to the Executive.

(e) Certain Termination Benefits. Except as expressly provided in this Section 6(e), or in Section 6(a) with respect to death,
Section 6(f) with respect to a Change-of-Control, Section 6(g) with respect to non-renewal, Section 7 with respect to disability, or as may be required by applicable law, the Executive shall not be entitled to any benefits in
connection with the termination of this Agreement. In the event of termination by the Employer without Cause pursuant to Section 6(b) or by the Executive with Good Reason pursuant to Section 6(c), the Executive shall be entitled to the
following benefits:

(i) For a period of twelve (12) months subsequent to the date of termination (the Benefit End Date),
the Employer shall continue to pay the Executive a salary and benefits in accordance with Sections 4(a) and 4(d), said payments to be made on the same periodic dates as salary payments would have been made to the Executive had he not been
terminated.



6



---

(ii) For the period subsequent to the date of termination until the Benefit End Date, the Executive
shall continue to receive medical, dental and life insurance benefits pursuant to plans made available by the Employer to its employees at the expense of the Employer to substantially the same extent the Executive received such benefits on the date
of termination (it being acknowledged that the post-termination plans may be different from the plans in effect on the date of termination). For purposes of application of such benefits, the Executive shall be treated as if he had remained in the
employ of the Employer, and service credits will continue to accrue during such period as if the Executive had remained in the employ of the Employer.

(iii) If, in spite of the provisions of Section 6(e)(ii) above, benefits or service credits under any medical, dental or life insurance plan shall not be payable or provided under any such plan to the Executive,
or to the Executives dependents, beneficiaries or estate, because the Executive is no longer deemed to be an employee of the Employer, the Employer shall pay or provide for payment of equivalent benefits, taking into account service credits
for such benefits to the Executive, or to the Executives dependents, beneficiaries or estate.

(iv) The Employers obligation
to provide the Executive with medical or dental insurance pursuant to subsections 6(e)(ii) and 6(e)(iii) hereof shall terminate with respect to each particular type of insurance in the event the Executive becomes employed and has made available to
him in connection with such employment at the expense of the employer that particular type of insurance, so long as such insurance is substantially similar to the insurance provided by the Employer.

(v) In the event the Executive becomes employed and has made available to him in connection with such employment at the expense of the employer life
insurance which is substantially similar to the life insurance provided by the Employer pursuant to Subsections 6(e)(ii) and 6(e)(iii) hereof, the Employer shall be required to provide the Executive with life insurance pursuant to such subsections
only in an amount equal to the excess, if any, of the amount of life insurance which would be provided by the Employer pursuant to such subsections if the Executive had not been provided with life insurance in connection with his new employment over
the amount of life insurance provided by the Executives new employer.

(f) Change-of-Control Termination Benefits. To the
extent a Change-of-Control occurs during the term of this Agreement, the Executive, at his sole option, may deem such Change-of-Control to be a termination of his employment by the Employer without Cause. Consequently, he shall be entitled to
receive the termination benefits referenced in Section 6(e) hereof. In addition, upon a Change-of-Control all unvested ISOs and Restricted Shares granted pursuant to this Agreement shall immediately vest. To the extent a Change-of-Control
occurs during the third year of this Agreement, the Executive may deem such Change-of-Control to be a failure by the Employer to renew this Agreement, thereby enabling the Executive to receive the benefits referenced in Section 6(g) hereof in



7



---

lieu of those benefits provided in Section 6(e) hereof. For the purposes of this Agreement, the term Change-of-Control shall mean a change
of control of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act), whether or not the
Employer is then subject to such reporting requirement; provided, that, without limitation, such a change of control shall be deemed to have occurred if:

(i) subsequent to the date hereof, any person (as such term is used in Sections 13(d) and 14(d) of the Exchange Act (a Person)) is or becomes the beneficial owner (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Employer (not including in the amount of the securities beneficially owned by such person any such securities acquired directly from the Employer or its affiliates) representing
in excess of fifty percent (50%) or more of the voting power of the Employers then outstanding voting securities; provided however, that for purposes of this Agreement, the term Person shall not include (A) the Employer,
(B) a trustee or other fiduciary holding securities under an employee benefit plan of the Employer, (C) an underwriter temporarily holding securities pursuant to an offering of such securities, or (D) a corporation owned, directly or
indirectly, by the shareholders of the Employer in substantially the same proportions as their ownership of stock of the Employer; and provided, further, that for purposes of this subsection (i), there shall be excluded any Person who becomes such a
beneficial owner in connection with an Excluded Transaction (as defined below);

(ii) the following individuals cease for any reason to
constitute a majority of the number of directors then serving: individuals who, on the date hereof, constitute the Board of Directors and any new director (other than a director whose initial assumption of office is in connection with an actual or
threatened election contest including, but not limited to, a consent solicitation, relating to the election of directors of the Employer) whose appointment or election by the Board of Directors or nomination for election by the Employers
shareholders was approved or recommended by a vote of at least two-thirds of the directors then still in office who either were directors on the date hereof or whose appointment, election or nomination for election was previously approved or
recommended; or

(iii) there is consummated a merger or consolidation of the Employer with any other corporation, other than a merger or
consolidation (an Excluded Transaction) which would result in the voting securities of the Employer outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting
securities of the surviving corporation or any parent thereof) at least 50% of the combined voting power of the voting securities of the entity surviving the merger or consolidation (or the parent of such surviving entity) immediately after such
merger or consolidation, or the shareholders of the Employer approve a plan of complete liquidation of the Employer, or there is consummated the sale or other disposition of all or substantially all of the Employers assets.

Notwithstanding anything to the contrary contained in this Agreement, the acquisition of Mimotopes Pty Ltd, an Australian limited company, by the
Employer pursuant to the terms, exhibits, and schedules specifically contained within that certain Stock



8



---

Purchase Agreement, dated as of November 24, 2006, by and among the Employer, PharmAust Limited, an Australian limited company, and PharmAust Chemistry
Ltd, an Australian limited company, shall not be deemed to be a Change-of Control for the purposes of this Agreement.

(g) Non-Renewal Termination Benefits. To the extent the Employer has not offered to
(i) renew this Agreement or (ii) enter into another employment arrangement with substantially similar or better terms for the Executive on or before the date that is one year prior to the Expiration Date, the Executive may declare the
Employer in breach of this Agreement, terminate this Agreement and receive the benefits indicated in Section 6(e)(i)  (v) hereof for a period beginning on the date of such termination and ending on December 31stof the year following the date of such termination.

(h) Litigation and Regulatory Cooperation. During the term of this Agreement and the period in which the Executive is subject to the obligations in Section 8, the Executive shall cooperate fully with the Employer in the defense
or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Employer which relate to events or occurrences that transpired while the Executive was employed by the Employer. The
Executives full cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Employer at mutually
convenient times. The Executive shall also cooperate fully with the Employer in connection with any examination or review of any federal or state regulatory authority as any such examination or review relates to events or occurrences that transpired
while the Executive was employed by the Employer. If such cooperation is required after the Executive ceases to receive cash compensation from the Employer under Section 4 or Section 6, the Employer shall pay the Executive for such
cooperation a fee of one hundred dollars ($100.00) per hour, payable monthly in arrears, and will reimburse the Executive for any reasonable out-of-pocket expenses incurred in connection therewith.

7. Disability. If, due to physical or mental illness, the Executive shall be disabled so as to be unable to perform substantially all of
his duties and responsibilities hereunder, which disability lasts for an uninterrupted period of at least 90 days or a total of at least 180 days in any calendar year (as determined by the opinion of an independent physician selected by the Board of
Directors of the Employer), the Employer, acting through its Board of Directors, may designate another executive to act in his place during the period of such disability. Notwithstanding any such designation, the Executive shall continue to receive
his full salary and benefits under Section 4 of this Agreement until he becomes eligible for disability income under the Employers disability income plan. While receiving disability income payments under such plan, the Executive shall
receive the difference between such payments and his salary under Section 4(a) (but not any bonus, except as accrued through the date of determination of disability) and shall continue to participate in the Employers benefit plans and to
receive other benefits as specified in Section 4 until the Expiration Date.

her relationship with the Employer, or solicit or encourage any customer of the Employer to terminate its relationship with the Employer or to conduct with any other Person any business or activity which such customer conducts or could conduct with

and will have access to confidential information of the Employer (and its affiliates, vendors, customers, and others having business dealings with it) including, without limitation, information and knowledge pertaining to products and services,
sales and profit figures, customer and client lists and information related to relationships between the Employer and its affiliates, customers, vendors, and others having business dealings with it (collectively, the Confidential
Information). The Executive acknowledges that the Confidential Information is a valuable and unique asset of the Employer (and its affiliates, vendors, customers, and others having business dealings with it) and covenants that, both during and
after the term of his employment by the Employer, he will not disclose any Confidential Information to any person or use any Confidential Information (except as his duties as an employee of the Employer may require) without the prior written
authorization of the Board of Directors of the Employer. The Executive further agrees that all files, computer programs and files, letters, memoranda, reports, records, data, sketches, drawings, program listings or other written, photographic, or
other tangible material containing Confidential Information, whether created by the Executive or others, which shall come into his custody or possession, shall be and are the exclusive property of the Employer to be used by the Executive only in the
performance of his duties for the Employer. All such records or copies thereof and all tangible property of the Employer in the custody or possession of the Executive shall be delivered to the Employer, upon the earlier of (i) a request by the
Employer or (ii) termination of the Executives employment. After such delivery, the Executive shall not retain any such records or copies thereof or any such tangible property. The obligation of confidentiality imposed by this Section
shall not apply to information that is required by law, regulation or judicial or governmental authorities to be disclosed or that otherwise becomes part of the public domain by means not involving a breach of a convenant of confidentiality owed to
the Employer.

(c) Rights and Remedies Upon Breach. If the Executive breaches, or threatens to commit a breach
of, any of provisions of Section 8 hereof (collectively, the Restrictive Covenants), the Employer shall have the following rights and remedies, each of which rights and remedies shall be independent of the other and severally
enforceable, and all of which rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available to the Employer under law or in equity:

(i) The Executive recognizes and agrees that the violation of the Restrictive Covenants may not be reasonably or adequately compensated in damages and
that, in addition to any other relief to which the Employer may be entitled by reason of such violation, it shall also be entitled to permanent and temporary injunctive and equitable relief and, pending determination of any dispute with respect to
such violation, no bond or security shall be required in connection therewith. Without limiting the generality of the foregoing, the Executive specifically acknowledges that showing by the Employer of any breach of any provision of any Restrictive
Covenant shall constitute, for the purposes of all judicial determinations of the issue of injunctive relief, conclusive proof of all of the elements necessary to entitle the Employer to interim and permanent injunctive relief against the Executive
with respect to such breach. If any dispute arises with respect to this Section 8, without limiting in any way any other rights or remedies to which the Employer may be entitled, the Executive agrees that the Restrictive Covenants shall be
enforceable by a decree of specific performance.

(ii) The Employer shall have the right and remedy to require the Executive to account
for and pay over to the Employer all compensation, profits, monies, accruals, increments or other benefits (collectively, Benefits) derived or received by the Executive as the result of any transactions constituting a breach of any of
the Restrictive Covenants, and the Executive shall account for and pay overall such Benefits to the Employer.

(d) Severability of
Covenants. If any of the Restrictive Covenants, or any part thereof, or any of the other provisions of this Section 8 is held by a court of competent jurisdiction or any other governmental authority to be invalid, void, unenforceable or
against public policy for any reason, the remainder of the Restrictive Covenants or such other provisions shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and such court or authority shall be empowered
to substitute, to the extent enforceable, provisions similar thereto or other provisions so as to provide to the Employer to the fullest extent permitted by applicable law, the benefits intended by such provisions.

(e) Enforceability in Jurisdictions. The parties intend to and hereby confer jurisdiction to enforce the Restrictive Covenants and the other
provision of this Section 8 upon the courts of any jurisdiction within the geographical scope of such Restrictive Covenants or other provisions, as the case may be. If the courts of any one or more of such jurisdictions hold the Restrictive
covenants or other provisions, as the case may be, wholly invalid or unenforceable by reason of the breadth or scope or otherwise, it is the intention of the parties that such determination not bar or in any way affect the Employers right to
the relief provided above in the



11



---

courts of any other jurisdiction within the geographical scope of such Restrictive Covenant or other provisions, as the case may be, as they relate to each
jurisdiction being, for this purpose, severable into diverse and independent covenants.

(f) Definition and Survival. For purposes
of this Section 8 only, the term Employer shall mean Commonwealth Biotechnologies, Inc. and any of its subsidiaries and affiliates. All provisions of this Section 8 shall survive termination of this Agreement.

9. Conflicting Agreements. The Executive hereby represents and warrants that the execution of this Agreement and the performance of his
obligations hereunder will not breach or be in conflict with any other agreement to which he is a party or by which he is bound, and that he is not subject to any covenants against competition or similar covenants which would affect the performance
of his obligations hereunder.

10. Withholding. All payments made by the Employer under this Agreement shall be net of any
tax or other amounts required to be withheld by the Employer under applicable law.

11. Arbitration of Disputes. Any
controversy or claim arising out of or relating to the employment relationship between the Executive and the Employer, this Agreement or any breach thereof, other than a controversy or claim relating to Section 8 of this Agreement, shall be
settled by arbitration in accordance with the laws of the Commonwealth of Virginia by three arbitrators, one of whom shall be appointed by the Employer, one by the Executive and the third by the first two arbitrators. If the first two arbitrators
cannot agree on the appointment of a third arbitrator, then the third arbitrator shall be appointed by the American Arbitration Association in the City of Richmond. Such arbitration shall be conducted in the City of Richmond in accordance with the
rules of the American Arbitration Association, except with respect to the selection of arbitrators which shall be as provided in this Section 11. Judgment upon the award rendered by the arbitrators may be entered in any court having
jurisdiction thereof. The party against whom the arbitrators shall render an award shall pay the other partys reasonable attorneys fees and other reasonable costs and expenses in connection with the enforcement of its rights under this
Agreement (including the enforcement of any arbitration award in court), unless and to the extent the arbitrators shall determine that under the circumstances recovery by the prevailing party of all or a part of any such fees and costs and expenses
would be unjust.

12. Assignment; Successors and Assigns, etc. Neither the Employer nor the Executive may make any assignment
of this Agreement or any interest herein, by operation of law or otherwise, without the prior written consent of the other party; provided, however, that the Employer may assign its rights under this Agreement without the consent of the Executive in
the event that the Employer shall hereafter effect a reorganization, consolidate with or merge into any other Person, or transfer all or substantially all of its properties or assets to any other Person. This Agreement shall inure to the benefit of
and be binding upon the Employer and the Executive, their respective successors, executors, administrators, heirs and permitted assigns. In the event of the Executives death prior to the completion by the Employer of all payments due him under
this Agreement, the Employer shall continue such payments to the Executives beneficiary designated in writing to the Employer prior to his death (or to his estate, if he fails to make such designation).

13. Enforceability. If any portion or provision of this Agreement shall to any extent be
declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable,
shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

14. Waiver. No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party. The failure of any party to require the performance of any term or obligation of
this Agreement, or the waiver by any party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.

15. Notices. Any notices, request, demands and other communications provided for by this Agreement shall be sufficient if in writing and
delivered in person or sent by registered or certified mail, postage prepaid (in which case notice shall be deemed to have been given on the third day after mailing), or by overnight delivery by a reliable overnight courier service (in which case
notice shall be deemed to have been given on the day after delivery to such courier service) to the Executive at the last address the Executive has filed in writing with the Employer or, in the case of the Employer, at its main offices, attention of
the Board of Directors.

16. Entire Agreement; Amendment. This Agreement may be amended or modified only by a written
instrument approved by each of the Board of Directors of the Employer and the Compensation Committee thereof, signed by the Executive and by a duly authorized representative of the Employer who is the Chairman of the Board or President or an
Executive Vice President of the Employer and who is not the Executive. This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and no agreements or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either party which are not expressly set forth in this Agreement.

17.
Governing Law. This is a Virginia contract and shall be construed under and be governed in all respects by the laws of the Commonwealth of Virginia, without giving effect to the choice of law principles of any state.

18. Legal Counsel. This Agreement has been prepared by Kaufman & Canoles, as counsel to the Company, after full disclosure of its
representation of the Company and with the consent of the Executive. The Executive has reviewed the contents of this Agreement and fully understands its terms. The Executive acknowledges that he is fully aware of his right to the advice of counsel
independent from that of the Company, that Kaufman & Canoles, has advised him of such right and disclosed to him the risks in not seeking such independent advice, and that he understands the potentially adverse interests of the parties with
respect to this

Agreement to him and that he has been advised of the importance of seeking independent advice of counsel with respect to such consequences.
