 Dear Paul:

Board of Directors of the Company effective September 14, 2016, and as a result your employment with the Company will terminate, effective as of September 14, 2016 (the “Separation Date”). The purpose of this letter (this
“Agreement”) is to confirm the terms concerning your separation from employment, as follows: 
 1. Termination of
Employment. Effective as of the Separation Date your employment with the Company will terminate and you will cease to serve in any and all officer positions you hold with the Company or any of its Affiliates, any and all memberships you

2. Final Salary and Vacation Pay. You acknowledge that, on or before the Separation Date, you will receive pay for all work
you performed for the Company through the Separation Date, to the extent not previously paid, as well as pay, at your final base rate of pay, for any vacation days you have earned but not used as of the Separation Date, determined in accordance with
Company policy and as reflected on the books of the Company. 
 3. Severance Benefits. In consideration of your signed
acceptance of this Agreement and subject to your meeting in full your obligations under it, including signing an effective Release (as defined below) and complying with the Continuing Obligations (as defined below), you will receive the following
severance benefits: 
 (a) The Company will pay you the amount of $543,016.22, which is equal to (i) one year of your base salary of
$477,409.00, as in effect on the Separation Date, plus (ii) $65,607.22, which reflects a pro-rata portion of the Maximum Bonus (as defined in the letter agreement between you and the Company dated October 31, 2008 (the “Employment
Agreement,” attached hereto as Exhibit A)) you would be eligible to receive in 2016 (collectively, the “Cash Severance Benefits”). The Cash Severance Benefits will be








 
paid in a lump sum on the first scheduled payroll date of the Company following the latest of (x) the Separation Date, (y) the date the Company receives the Release, and (z) the date the
revocation period specified in the Release expires. 
 (b) Provided you timely elect to continue medical and dental coverage under
COBRA, the Company will contribute toward your medical and dental benefits at the same rate as it contributes to medical and dental coverage for the Company’s other executive-level employees for twelve (12) months following the Separation Date
(the “COBRA Benefits”). In addition, the Company will pay you a cash amount equal to the premium cost that the Company would incur to provide you life and disability insurance coverage for twelve (12) as the rates in effect on
the Separation Date (the “Benefits Payment”). 
 (c) 180,100 of the Options (as defined below) will immediately vest in
full upon the Separation Date. The accelerated vesting described in this Section 3(c), collectively with the Cash Severance Benefits, the COBRA Continuation, and the Benefits Payment are referred to herein in as the “Severance
Benefits.” 
 4. Acknowledgement of Full Payment and Withholding.  

(a) You acknowledge and agree that the payments provided under Section 2 and Section 3 of this Agreement, and the vesting of the Options under
Section 3(c), are in complete satisfaction of any and all compensation or benefits due to you from the Company, whether for services provided to the Company or otherwise, through the Separation Date and that, except as expressly provided under this
Agreement, no further compensation or benefits are owed or will be paid to you.
 (b) All payments made by the Company under this Agreement
shall be reduced by any tax or other amounts required to be withheld by the Company under applicable law and all other lawful deductions authorized by you.

5. Status of Employee Benefits, Paid Time Off, Expenses, and Equity Awards.  

(a) Except for any right you may have to continue your participation and that of your eligible dependents in the Company’s medical,
dental, and vision plans under the federal law known as “COBRA” or similar applicable law, your participation in all employee benefit plans of the Company will end as of the Separation Date, in accordance with the terms of those
plans. You acknowledge that you will not continue to earn paid time off or other similar benefits after the Separation Date. You will receive information about your COBRA continuation rights under separate cover. 

(b) Within two (2) weeks following the Separation Date, you must submit your final expense reimbursement statement reflecting all business
expenses you incurred

through the Separation Date, if any, for which you seek reimbursement, and, in accordance with Company policy, reasonable substantiation and documentation for the same. The Company will
reimburse you for your authorized and documented expenses within thirty (30) days of receiving such statement pursuant to its regular business practice. 

(c) You acknowledge and agree that as of the Separation Date, you will hold 1,441,780 options to purchase common stock of the Company,
1,235,530 of which will be vested as of the Separation Date (taking into account the accelerated vesting under Section 3(c) above), and 206,250 of which will be unvested as of the Separation Date (the “Options”). You further
acknowledge and agree that each of the Options that is vested as of the Separation Date will remain outstanding and exercisable until the date that is twelve (12) months following the Separation Date, and each of the Options that is unvested as of
the Separation Date will automatically terminate upon your termination of employment. In addition, you acknowledge and agree that the fiscal year 2017 award to you of 445,000 options to purchase common stock of the Company that was subject to
approval by the stockholders of the Company will automatically terminate upon your termination of employment. 
 6. Continuing
Obligations, Confidentiality and Non-Disparagement.  
 (a) You acknowledge that you continue to be bound by your
obligations under the Employment Agreement and the Non-Competition Agreement between you and the Company dated October 3, 2005 (the “Non-Competition Agreement,” attached hereto as Exhibit B) that survive the termination of
your employment by necessary implication or the terms thereof (the “Continuing Obligations”). For the avoidance of doubt, you acknowledge and agree that your resignation constitutes a termination of employment covered by
Section 3(b) of the Non-Competition Agreement. Nothing in this Agreement or the Continuing Obligations limits, restricts or in any other way affects your communicating with any governmental agency or entity, or communicating with any official
or staff person of a governmental agency or entity, concerning matters relevant to the governmental agency or entity. 
 (b) Subject to
Section 5(a) of this Agreement and as expressly provided in the Release, you agree that you will not disclose this Agreement or any of its terms or provisions, except to members of your immediate family and to your legal and tax advisors, and
then only on condition that they agree not to further disclose this Agreement or any of its terms or provisions to others, provided you may disclose the existence of, but not the terms of, this Agreement. However, the foregoing non-disclosure
obligation shall not apply to the extent this Agreement or any agreement referenced herein is publicly filed. 
 7. Return of Company
Documents and Other Property. In signing this Agreement, you represent and warrant that, except as may otherwise be agreed in writing by the Company, you will return to the Company, on or after the Separation Date, any and all documents,
materials and information (whether in hardcopy, on electronic media or otherwise) related to the business of the Company and its Affiliates (whether present or

otherwise), and all keys, access cards, credit cards, computer hardware and software, telephones and telephone-related equipment and all other property of the Company or any of its Affiliates in
your possession or control. Further, you represent and warrant that you will not retain any copy or derivation of any documents, materials or information (whether in hardcopy, on electronic media or otherwise) of the Company or any of its

network or system of the Company or any of its Affiliates, including, without limitation, the electronic mail system, and you agree that you will not do so. Further, you acknowledge that you have disclosed to the Company all passwords necessary or
desirable to obtain access to, or that would assist in obtaining access to, all information which you have password-protected on any computer equipment, network or system of the Company or any of its
Affiliates. For the purposes of this Agreement, “Affiliates” means all persons and entities directly or indirectly controlling, controlled by or under common control with the Company, where control may be by management authority, equity
interest or otherwise. 
 8. Employee Cooperation. You agree to cooperate with the Company and its Affiliates hereafter with
respect to all matters arising during or related to your employment, including, but not limited to, all matters in connection with any governmental investigation, litigation or regulatory or other proceeding which may have arisen or which may arise
following the signing of this Agreement. The Company will reimburse your out-of-pocket expenses incurred in complying with Company requests hereunder, provided such expenses are authorized by the Company in advance. 

9. General Release of Claims. In exchange for the Severance Benefits provided to you under this Agreement, to which you
would not otherwise be entitled, and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, you agree to sign and not revoke the general release of claims attached hereto as Exhibit C (the
“Release”) by the time period specified therein. You further acknowledge and agree that a signed and unrevoked Release is an express condition to your receipt and retention of the Severance Benefits.

 A-2 








 (a) Termination Upon Death or Disability: If you cease to be an employee of the Company
and the Subsidiary as a result of death or Disability, the Company will have no further obligation or liability to you hereunder other than for (i) Base Salary earned and unpaid at the date of termination, (ii) Bonus earned (i.e. all targets
or other requirements necessary to receive the Bonus have been met) but unpaid at the date of termination, if any, and (iii) compensation for accrued vacation, if any (the “Accrued Obligations”). However, nothing in this Agreement
shall adversely affect your rights or those of your family or beneficiaries under any applicable plans, policies or arrangements of the Company or the Subsidiary. 

(b) Termination by the Company for Cause or by You Without Good Cause: If the Company terminates your employment for Cause (as defined
in Section 8(d)) or if you terminate your employment other than for Good Cause (as defined in Section 8(d)), the Company and the Subsidiary shall have no further obligation or liability to you hereunder other than for payment of the Accrued
Obligations. 
 (c) Termination by the Company Without Cause or by You for Good Cause: If the Company terminates your employment
other than for Cause, or you terminate your employment for Good Cause, then, in addition to payment of the Accrued Obligations, you shall receive the following: 

(i) The Company will pay you, within thirty (30) days following the later of (a) the termination of employment, or (b) the date you deliver to
the Company a release of claims in accordance with Section 8(e), a lump-sum cash amount equal to the sum of (x) an amount equal to one year’s then-current Base Salary plus (y) a pro rata portion (based on the number of weeks worked in the year
of termination) of the Maximum Bonus (as defined in Section 8(d)) that would otherwise be payable to you in the year that the termination occurs, if any (the “Severance Payment”). The parties acknowledge and agree that the
obligation to pay the Severance Payment is solely that of the Company and that none of the directors or officers of the Company or the Subsidiary shall have any personal liability with respect thereto. You understand that payments to be made to you
pursuant to Section 3(c) of the Non-Competition Agreement shall be offset against (and consequently reduced by) any payments made to you hereunder, on a dollar-for-dollar basis. 

(ii) The Company will continue, for a period of twelve (12) months after termination, to provide you with medical benefits under (as the case
may be) the Company’s or the Subsidiary’s group medical plan, life insurance arrangements and disability arrangements equivalent to those provided to executive-level employees. To the extent that the Company is unable to provide such
benefits to you under its existing plans and arrangements, the Company will pay you cash amounts equal to the cost the Company or the Subsidiary would have incurred to provide those benefits. 

(iii) Notwithstanding the terms of any awards of stock options or restricted stock, all options to purchase Company stock held by you will
automatically and immediately vest and become exercisable upon such termination and remain exercisable for a 

  
 A-3 








 
period of six (6) months thereafter (except that incentive stock options shall be exercisable for only three (3) months thereafter), and all restricted stock held by you pursuant to the
restricted stock plans or arrangements of the Company shall automatically and immediately vest and no longer be subject to forfeiture. 

(iv) Notwithstanding any other provision of this Agreement, should any benefit payment that is described in this subsection (c) be subject to
Section 409A of the Internal Revenue Code of 1986 as amended, the Company is authorized to make payments in a manner that complies with the requirements of Section 409A. However, in the event that one or more provisions of Section 409A is violated,
the Company shall not be responsible for the payment of any tax liability, penalties or interest that are imposed upon you as a result of said violation, nor shall the Company be under any obligation to make you whole or otherwise compensate you for
such additional liability. 
 (d) Definitions: The following terms shall have the meanings set forth below: 

“Cause” shall mean, in respect of the termination of your employment by the Company, (a) willful malfeasance, gross
misconduct or gross negligence in your performance of the duties of your position that has a material adverse effect on the Company or the Subsidiary, (b) the material breach by you of this Agreement or of Sections 3(a), 4, 5 or 6 of the
Non-Competition Agreement, (c) fraud or dishonesty by you with respect to the Company, the Subsidiary or your employment, (d) your conviction of any crime that involves deception, fraud or moral turpitude or any felony (including, in each case,
entry of a guilty or nolo contendere plea and excluding traffic violations or similar minor offenses), or (e) your repeated or prolonged absence from work other than for illness, Disability or authorized vacation. The Company may treat a termination
of your employment as termination for Cause only after (i) giving you written notice of the intention to terminate for Cause, including a description of the conduct that the Company believes constitutes the basis for a Cause termination, and of your
right to a hearing by the Company’s Board of Directors, (ii) in the event of a termination under clause (a), (b) or (e) above, providing you with a 30-day period in which to cure the conduct giving rise to the Company’s notice of a Cause
termination, unless, with respect to clause (a) and (b) above, (I) in the Company’s reasonable judgment, protective action inconsistent with such cure period (e.g., immediate termination) is necessary to avoid harm to the Company of the
Subsidiary or (II) the Company reasonably determines that your conduct is egregious, in which event, the Company may shorten the cure period or terminate your employment immediately (subject to the requirements set forth in clauses (iii) and (iv)
below), (iii) at least 30 days after giving the notice, conducting a hearing by the Board at which you may be represented by counsel, and (iv) giving you written notice of the results of the hearing and the factual basis for the Board’s
determination of Cause, which shall require a vote of a majority of the members of the Board then in office other than yourself. Except in connection with your opportunity, if any, to cure the conduct giving rise to the Company’s notice of
termination for Cause as set forth in clause (ii) above, nothing in the foregoing sentence shall prevent the Company from terminating your employment pending any determination of Cause as set forth in the foregoing sentence, any such determination
shall be retroactive to the date of termination, and the Company shall not be obligated to compensate you hereunder for the period from such termination until such time, if any, as the Company’s Board of Directors determines that such
termination was not for Cause. Notwithstanding the foregoing, Cause shall not include an act or failure to act based on authority 

  
 A-4 








 
given pursuant to a resolution duly adopted by the Company’s Board of Directors or based on the advice of the Company’s General Counsel or willful failure due to incapacity resulting
from Disability or any actual or anticipated failure after you provide written notice of a termination for Good Cause. 

“Disability” shall mean physical or mental incapacity of a nature which prevents you, in the professional judgment of your
physician or, at the Company’s election, a board-certified physician mutually agreed upon by the Company and you, from performing the essential functions of your position with the Company or the Subsidiary with or without a reasonable
accommodation for a period of ninety (90) consecutive days or one hundred eighty (180) days during any consecutive 12-month period. 

“Good Cause” shall mean, in respect of the termination of your employment by you, (i) failure by the Company to maintain you
in the position of Managing Director (ii) a material diminution of your duties and responsibilities in such position or a material diminution of your authority with respect to such position, as described in Section 2 hereof, excluding for this
purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly after receipt of written notice thereof given by you, (iii) a breach by the Company of any material term of this Agreement
or the Non-Competition Agreement, or (iv) relocation of your principal place of work to a location more than thirty (30) miles from your address as set forth in Section 10 below without your prior consent. You may treat a resignation from employment
as termination for Good Cause only after (a) giving the Company written notice of the intention to terminate for Good Cause, (b) providing the Company at least 30 days after receipt of such notice to cure the conduct or action giving rise to Good
Cause, unless, with respect to clause (i) and (ii), you reasonably determine that the Company’s conduct is egregious and has resulted in significant, irreparable harm to you, in which event, you may shorten the cure period or terminate your
employment immediately, and (c) if applicable, the Company has failed to cure the action or conduct giving rise to Good Cause during the 30 day cure period. Notwithstanding anything herein to the contrary, a change in your title from Managing
Director to Chief Executive Officer shall not constitute Good Cause. 
 “Maximum Bonus” shall mean your bonus for the year
in which termination occurs, calculated on the assumption that all targets and formulas for determining such bonus have been met If no such targets or formulas have been established, then the Maximum Bonus shall be the total bonus you were eligible
to receive during the preceding fiscal year, calculated on the assumption that all targets and formulas for determining such bonus have been met. The Maximum Bonus (A) payable upon termination shall be reduced by any bonus payments relating to
services performed in the year in which termination occurs that (1) have already been paid to you as of the date of termination, (2) are payable to you as an Accrued Obligation hereunder, or (3) could have been earned during the year in which
termination occurs but that were not so earned because of the failure to achieve targets or formulas which are no longer able to be achieved, and (B) shall not include any bonus paid or payable in the year in which termination occurs to the extent
such payment represents payment for services rendered in a prior year. By way of illustration and not limitation, if you are paid a bonus on February 18, 2008 relating to your performance during all or part of the 2007 calendar year and you are
later terminated without Cause on August 31, 2008, the Maximum Bonus payment due upon 

  
 A-5 








 
termination will not be reduced by the bonus payment received on February 15, 2008, nor shall the amount of the February 15, 2008 bonus be included as part of the Maximum Bonus, because such
payment relates to services rendered in the year preceding the year in which termination occurs. If you are paid a bonus on July 15, 2008 relating to your performance during the first and/or second quarter of the 2008 calendar year and are later
terminated without Cause on August 31, 2008, the Maximum Bonus payment due upon termination will be reduced by the bonus payment received on July 15, 2008 because such payment relates to services rendered in the year in which termination occurs, and
if you do not receive a bonus for the first and/or second quarter of the 2008 calendar year because quarterly performance objectives had not been achieved, the amount of such bonus that could have been earned shall not be included in determining the
Maximum Bonus. 
 (e) Release: Notwithstanding anything to the contrary contained in this Agreement, in order for you to be eligible
for any severance benefits under this Section 8, you must execute and deliver to the Company (and not revoke within seven (7) days of executing) the release of claims in the attached as Exhibit A hereto. 

9. Non-Disparagement: You will not at any time during or after the term of your employment hereunder make any statement to any person,
including, without limitation, employees, customers, suppliers or competitors of the Company or the Subsidiary, that is derogatory or negative about the Company or the Subsidiary or their respective affiliates or any statement regarding the future
plans of the Company. This Section 9 will not apply to any statements made by you (i) in support of any claim or defense asserted by you in any mediation, arbitration or litigation process or proceeding between you and the Company or the Subsidiary
and (ii) made only within the specific forum (i.e. arbitral tribunal, courtroom) in which such mediation, arbitration or litigation is taking place. 

10. Notices: Any notices required or permitted to be sent under this Agreement shall be effective when delivered by hand or mailed by
registered or certified mail, return receipt requested, and addressed as follows:

 11. Waiver: The failure of either party to enforce any of the provisions of this Agreement
shall not be deemed a waiver thereof. No provision of this Agreement shall be deemed to have been waived or modified unless such waiver or modification shall be in writing and signed by both parties hereto. 

12. Arbitration: All controversies and disputes between or among any of the parties hereto arising out of or in connection with the
interpretation, performance or enforcement of this Agreement, whether based on federal, state or foreign law and whether grounded in common law or statutory law, shall be settled exclusively by arbitration conducted as provided herein, and otherwise
in accordance with the National Employment Rules of the American Arbitration Association. 
 (a) Procedure: The arbitration shall be
administered by the American Arbitration Association, as follows: 
 (i) the arbitration shall be conducted in Boston, Massachusetts by a
panel of three (3) arbitrators, jointly selected by the parties, except that if the parties are unable to agree on all three arbitrators within fifteen (15) days after demand for arbitration has been made (or such later time as the parties may
agree), the arbitration shall be conducted by three (3) arbitrators as are selected in accordance with the applicable rules of the American Arbitration Association; 

(ii) final decision shall be by a majority of the arbitrators, which arbitrators shall prepare and deliver a written reasoned award. Judgment
upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof; and 
 (iii) all costs and fees
relating to the arbitration shall be borne by the losing party, except that if the arbitrators determine that any party has prevailed in part and lost in part, the costs and fees relating to the arbitration shall be allocated between the parties as
equitably determined by the arbitrators. 
 (b) Refusal to Arbitrate: The failure or refusal of any party to submit to arbitration
shall be deemed a breach of this Agreement. If a party seeks and secures judicial intervention requiring enforcement of this Section 12, such party shall be entitled to recover from the other party in such judicial proceeding all costs and expenses,
including reasonable attorneys’ fees, that it was thereby required to incur. 
 (c) Sole Procedure: The procedures specified in
this Section 12 shall be the sole and exclusive procedures for the resolution of disputes between the parties arising out of or relating to this Agreement; provided, however, that a party, without prejudice to the above procedures, may seek a
preliminary injunction or other equitable relief if in its judgment such action is necessary to avoid irreparable damage or to preserve the status quo. Despite such action the parties will continue to participate in good faith in the procedures
specified in this Section 12. 

  
 A-7 








 13. No Duty to Mitigate; No Offset: Benefits payable under this Agreement as a result of
termination of your employment will be considered severance pay in consideration of your past services and your continued service or obligations from and after the date of execution of this Agreement, and your entitlement thereto will neither be
governed by any duty to mitigate your damages by seeking further employment or offset by any compensation you may receive from other employment following the date of your termination of employment. Notwithstanding the foregoing, you agree that the
Company may cease its payment for, or provision of, one or more of the continued benefits under Section 8(c)(ii) during the twelve month period following the date of your termination from employment to the extent that you obtain comparable benefit
coverage with another employer. This provision shall be applied in an ad seriatim basis so that the Company may only cease payment of those comparable benefits that you obtain with another employer. You agree to notify the Company as soon as
practicable in the event that you obtain comparable coverage or benefits during the period noted above and you acknowledge that the Company’s obligation to continue payment for, or provision of, benefits shall cease from and after the date you
obtain comparable coverage. 
 14. Successors: This agreement shall inure to and be binding upon the Company’s successors and
assigns. The Company shall require any successor to all or substantially all of the business or assets of the Company by sale, merger or consolidation (where the Company is not the surviving corporation), lease or otherwise, to expressly assume this
Agreement. This Agreement is not otherwise assignable by the Company or you. 
 15. Rights of Survivors: If you die after becoming
entitled to benefits under this Agreement following termination of employment but before all such benefits have been provided, (a) all unpaid cash amounts will be paid to your designated beneficiary or, if no such beneficiary has been designated, to
your estate, (b) all applicable insurance coverage will be provided to your family as though you had continued to live, to the extent permitted under the plans, and (c) any stock options that become exercisable under Section 8 will be exercisable by
the beneficiary or, if none, the estate. 
 16. Entire Agreement; Termination: This Agreement together with the Non-Competition
Agreement shall constitute the entire agreement of the parties pertaining to this subject matter and shall supersede all prior agreements, representations and understandings of the parties with respect to such subject matter. Any and all employment,

 17. Partial Invalidity. If any provision in this Agreement is held by a court of competent
jurisdiction to be invalid, void or unenforceable, the remainings nevertheless shall continue in full force and effect without being impaired or invalidated in any manner.

which together shall constitute one and the same instrument.

Non-Competition Agreement

 NON-COMPETITION AGREEMENT 

IN CONSIDERATION of and as a condition to my (i) receiving consideration pursuant to the terms of the Agreement and Plan of Merger, dated
October 3, 2005 (the “MERGER AGREEMENT”) by and among pSivida Limited (“PARENT”), pSivida Inc. and Control Delivery Systems, Inc. (the “COMPANY”), and (ii) receiving an offer of employment with Parent consistent with
the terms set forth in Section 2(b) below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, I, Paul Ashton (referred to herein as “I”, “ME” or as “EXECUTIVE”),
agree with Parent as follows: 
 1. DEFINITIONS. 

(a) “AGREEMENT” shall mean this Non-Competition Agreement. 

(b) “CAUSE” shall mean, in respect of the termination of Executive’s employment by Parent, (a) willful malfeasance, gross
misconduct or gross negligence in the performance by Executive of the duties of his position that has a material adverse effect on the Parent, (b) the material breach by Executive of Sections 3(a), 4, 5 or 6 of this Agreement, (c) fraud or
dishonesty by Executive with respect to Parent or any of its affiliates or his employment, (d) Executive’s conviction of any crime that involves deception, fraud or moral turpitude or any felony (including, in each case, entry of a guilty or
nolo contendere plea, and, excluding traffic violations or similar minor offenses), or (e) repeated or prolonged absence from work by Executive other than for illness, Disability or authorized vacation. Parent may treat a termination of
Executive’s employment as termination for Cause only after (i) giving Executive written notice of the intention to terminate for Cause, including a description of the conduct that the Parent believes constitutes the basis for a Cause
termination, and of his right to a hearing by Parent’s Board of Directors (the “Board”), (ii) in the event of a termination under clause (a), (b) or (e) above, providing Executive a 30-day period in which to cure the conduct giving
rise to the Parent’s notice of a Cause termination, unless, with respect to clause (a) and (b) above, (I) in Parent’s reasonable judgment, protective action inconsistent with such cure period (e.g., immediate termination) is necessary to
avoid harm to Parent or (II) Parent reasonably determines that Executive’s conduct is egregious, in which event, Parent may shorten the cure period or terminate Executive’s employment immediately (subject to the requirements set forth in
clauses (iii) and (iv) below), (iii) at least 30 days after giving the notice, conducting a hearing by the Board at which Executive may be represented by counsel, and (iv) giving Executive written notice of the results of the hearing and the factual
basis for the Board’s determination of Cause, which shall require a vote of a majority of the members of the Board then in office other than Executive. Except in connection with Executive’s opportunity, if any, to cure the conduct giving
rise to Parent’s notice of termination for Cause as set forth in clause (ii) above, nothing in the foregoing sentence shall prevent Parent from terminating Executive’s employment pending any determination of Cause as set forth in the
foregoing sentence, any such determination shall be retroactive to the date of termination, and Parent shall not be obligated to compensate Executive hereunder for the period from such termination until such time as a determination by Parent’s
Board of Directors that such termination was not for Cause. Notwithstanding the foregoing, cause shall not include an act or failure to act based on authority given pursuant to a resolution duly adopted by the Board or based on the advice of
Parent’s General Counsel or willful failure due to incapacity resulting from Disability or any actual or anticipated failure after Executive provides written notice of a termination for Good Cause.

 (c) “CLOSING” shall have the meaning set forth in the Merger Agreement. 

(d) “DEVELOPMENTS” shall have the meaning set forth in Section 5(a). 

(e) “DISABILITY” shall mean physical or mental incapacity of a nature which prevents Executive, in the professional judgment of
Executive’s physician or, at Parent’s election, a board-certified physician mutually agreed upon by Parent and Executive, from performing the essential functions of Executive’s position with Parent with or without a reasonable
accommodation for a period of ninety (90) consecutive days or one hundred eighty (180) days during any consecutive 12-month period. 
 (f)
“EFFECTIVE TIME” shall have the meaning set forth in the Merger Agreement. 
 (g) “GOOD CAUSE” shall mean, in respect of
the termination of Executive’s employment by Executive, (i) failure by Parent to maintain Executive in the positions of Head of R&D Ophthalmology for the Surviving Company and Executive Director Strategy of Parent, without Executive’s
consent, (ii) a material diminution of Executive’s duties and responsibilities in such positions or a material diminution of Executive’s authority with respect to such positions, as described in Section 2(b) hereof and otherwise set forth
in the employment agreement referenced therein (assuming the parties execute such employment agreement), excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by Parent promptly
after receipt of written notice thereof given by Executive, (iii) a breach by Parent of any material term of this Agreement or the employment agreement referenced in Section 2(b) (assuming the parties execute such employment agreement), or (iv)
relocation of Executive’s principal place of work to a location more than thirty (30) miles from Executive’s address set forth in Section 11(e) below without Executive’s consent. Executive may treat a resignation from employment as
termination for Good Cause only after (a) giving Parent written notice of the intention to terminate for Good Cause, (b) providing Parent at least 30 days after receipt of such notice to cure the conduct or action giving rise to Good Cause, unless,
with respect to clause (i) and (ii), Executive reasonably determines that Parent’s conduct is egregious and has resulted in significant, irreparable harm to Executive, in which event, Executive may shorten the cure period or terminate his
employment immediately, and (c) if applicable, Parent has failed to cure the action or conduct giving rise to Good Cause during the 30 day cure period. 

(h) “MERGER” shall have the meaning set forth in the Merger Agreement. 

(i) “PROPRIETARY INFORMATION” shall have the meaning set forth in Section 4(a).

 Page 3 of 10 
  

 (l) “SURVIVING COMPANY” shall have the meaning set forth in the Merger Agreement.

 2. EFFECTIVENESS. 
 (a)
This Agreement shall enter into full force and effect as of the Effective Time. In the event that the Merger Agreement is terminated prior to the Effective Time, this Agreement shall be null and void and neither party shall have any rights or
obligations hereunder. 
 (b) Parent represents that, prior to the Effective Time, it shall provide Executive with an employment agreement
setting forth the material terms of his employment with Parent as of the Effective Time. Such employment agreement shall include, among other things, the following material terms: (i) a title Head of Research & Development Ophthalmology of the
Surviving Company, responsible for duties typically associated with such position; (ii) a title with Parent of Executive Director Strategy, reporting directly to Parent’s chief executive officer, responsible for, among other things, the
production of overall strategic business and development plans; (iii) a title of interim President of the Surviving Company, responsible for, among other things, ensuring effective communication among Parent business units particularly with respect
to milestones and participation in the general management of Parent including regular meetings and discussions with Parent’s chief executive officer and chairman; (iv) a compensation package commensurate with other senior executives of Parent,
which shall include, without limitation: (A) a base salary of $300,000 per year, (B) annual discretionary bonus eligibility on terms that are no less favorable than that which Executive was entitled as of the date of this Agreement, (C) entitlement
to benefits that are no less favorable than those to which Executive was entitled as of the date of this Agreement, and (D) a grant of options to purchase capital stock in the Parent commensurate with other senior executives of Parent, including
without limitation, subject to confirmation of Parent’s remuneration committee and shareholder approval, 500,000 options vesting as to half in 12 months and the balance in 24 months, subject to achieving milestones; (v) four (4) weeks paid
vacation per calendar year; (vi) a principal work location located no more than thirty (30) miles from Executive’s address set forth in Section 11(e) below without Executive’s consent; and (vii) eligibility for severance and related
post-termination benefits on terms no less favorable to Executive than those set forth in that certain Severance Agreement between Executive and Company dated February 20, 2004, as amended on August 17, 2004 (the “Severance Agreement”) and
no greater than those set forth in that certain Change in Control Agreement between Executive and Company dated August 17, 2004 (the “Change in Control Agreement”), which shall supercede and/or terminate Executive’s entitlement to
severance and related post-termination benefits pursuant to the Severance Agreement and the Change in Control Agreement. Parent and Executive agree to negotiate in good faith and use their reasonable best efforts to finalize the employment agreement
consistent with the terms of this Agreement and the contracts referenced herein. 
 (c) If (i) Parent fails to offer Executive an employment
agreement consistent with the requirements of Section 2(b), or Parent revokes such offer prior to the Effective Time for any reason and (ii), as a result of any of the above, Executive declines Parent’s offer of employment on or before the
Effective Time, then (I) this Agreement shall be null and void and neither party shall have any obligations hereunder, and (II) both the Severance Agreement and Change in Control Agreement shall continue to be in effect as of the Effective Time.


  









 Page 4 of 10 
  

 (d) If (i) Parent offers Executive an employment agreement consistent with the requirements
of Section 2(b) and (ii) Executive declines Parent’s offer of employment for any reason (other than his death or Disability), then (I) this Agreement shall continue in full force and effect as of the Effective Time and (II) the Severance
Agreement but not the Change in Control Agreement shall continue to be in effect upon the Effective Time. Such declination by Executive shall be deemed a termination of employment with Parent by Executive for other than Good Cause under Section 3(b)
below. 
 3. COVENANT NOT TO COMPETE. 

(a) I understand that Parent is engaged worldwide in the development, production and commercialization of drug delivery and other products
based on platform technologies. As of the Effective Time, I agree that I will not, during my employment with Parent, render (as a provider of services, consultant or otherwise) any services related to the business of Parent to anyone other than
Parent. 
 (b) In the event of: (i) the termination of my employment with Parent (other than termination by reason of death or Disability)
by me for any reason (whether voluntary on my part, or involuntary) other than Good Cause; or (ii) the termination of my employment with Parent (other than termination by reason of death or Disability) by Parent for Cause, I agree that for a period
of twelve (12) months from the date of such termination, I will neither: 
 (i) engage directly for myself, or in conjunction
with or on behalf of any person or entity, or otherwise own, manage, operate, control, acquire, hold any interest in, or participate in the ownership, management, operation or control of any person or entity engaged in the
development, production or commercialization of systems for the delivery of therapeutic drugs to the tissues in the posterior segment of the eye (the “REAR-OCULAR DRUG DELIVERY BUSINESS”), nor 

(ii) work for or become employed by or associated with (in any capacity, including without limitation officer, director,
employee, partner, stockholder, owner, member, proprietor, consultant, investor, salesperson, co-owner, trustee, promoter, technician, engineer, analyst, agent, representative, distributor, supplier, lender, advisor or manager) any person or
entity that is engaged in the Rear-Ocular Drug Delivery Business (the activities set forth in (i) and (ii) (as modified by the following paragraph) are collectively referred to as the “RESTRICTED ACTIVITIES”). 

Notwithstanding the foregoing, Parent accepts that nothing in this Section 3(b) shall prevent Executive from and after the date six (6) months after
termination of Executive’s employment from engaging in activities predominantly academic (and not commercial) in nature, including without limitation teaching, lecturing, writing and publishing articles or engaging in research; provided that
(I) unless approved by Parent in writing or otherwise described below, Executive receives no compensation (including without limitation salary, benefits, bonus, profit sharing, dividends, commissions, gifts, gratuities, or any other payments,
whether in cash or otherwise, present or future) whatsoever for such activities, other than reimbursement of expenses, for any period in which he is receiving severance payments from the Parent under this Agreement, his employment agreement with
Parent or any other agreement between Executive and Parent, except where the payment of compensation is required by the academic institution 

  









 Page 5 of 10 
  

 
and Executive agrees in writing to donate the full amount of such compensation to a registered charitable organization; and (II) in the course of engaging in such activities Executive does not
breach his obligations under this Agreement, including without limitation any obligations under Sections 4 and 5 herein. 
 Within six (6) months after the
termination of my employment for the reasons set forth above, Parent may at its sole discretion extend my obligations under this Section 3(b) for an additional twelve-month period; provided that in such a case Parent will pay me an amount equal to
my annual base salary as of the date of termination, to be paid in equal monthly installments over such additional twelve-month period. 

(c) In the event of the termination of my employment with Parent (other than termination by reason of death or Disability) (x) by me for Good
Cause, or (y) by Parent for any reason other than for Cause, I agree that, at Parent’s option, exercisable by written notice given: 
  

	 	(i)	not less than 30 days after Parent receives notice of such termination by me hereunder; and/or 

  

	 	(ii)	at the time of such termination by Parent hereunder; and/or 

  

	 	(iii)	with respect to a follow-on notice to Executive, no later than six months after the termination of my employment with Parent hereunder, 


for a period of up to twenty-four (24) months from the date of such termination, as specified in Parent’s notice or notices, I will not engage in any
Restricted Activities; provided that in such case Parent will pay me an amount equal to 1/24th of $800,000 for each month in the period specified, which amount may be offset against any severance or other payments owed to me in connection with the
termination of my employment as described in this Section 3(c). I understand that any payments made to me pursuant to the preceding sentence are made in consideration of my not engaging in any Restricted Activities or otherwise violating the terms
of this Agreement, and that, in addition to any other rights or remedies available to Parent at law or in equity, Parent shall have the right to terminate such payments if, and only if, I engage in Restricted Activities during the specified period
or otherwise violate the terms of this Agreement and such conduct continues following my receipt of written notice from the Company that describes the basis for the Company’s contention that I have engaged in Restricted Activities or otherwise
violated the terms of this Agreement. I understand that the Company may provide more than one written notice to extend the noncompete period under this Section 3(c), provided that such notices are sent within the six (6) month period after the
termination of my employment. 
 (d) My obligations under this Section 3 shall extend to all geographical areas of the world in which
Parent, or any of its related companies, is offering its services, either directly or indirectly, through licenses or otherwise, during the time period specified in this Section 3. 

(e) I further agree that while I remain employed by Parent and for the duration of any period during which I am prohibited from engaging in
the Restricted Activities pursuant to this Section 3, I will not, on behalf of myself or any other person or entity, (i) compete for, or engage in the solicitation of, or attempt to divert or take away from the Company, Parent or any of their
affiliates, any customer of the Company, Parent or any of their affiliates who has done business with the Company, Parent or any of their affiliates, as the case may be, during the period of my employment by Parent;


  









 Page 6 of 10 
  

 
(ii) compete for, solicit or attempt to divert or take away from the Company, Parent or any of their affiliates, any prospective customer that has within the twelve (12) month period prior to
such termination, expressed an interest in doing business with the Company, Parent or any of their affiliates and about which I learned during my employment with Parent; or (iii) hire or engage or attempt to hire or engage any individual, or attempt
to induce an individual to terminate their employment or other service arrangement, who was an employee of or other service provider to the Company, Parent or any of their affiliates at any time during the twelve (12) month period prior to my
termination from employment. 
 (f) Further, while I remain employed by Parent and for the duration of any period during which I am
prohibited from engaging in the Restricted Activities pursuant to this Section 3, I shall not, directly or indirectly, make or cause to be made to any Person any disparaging, derogatory or other negative statement about the Company, Parent or any of
their affiliates, including their businesses, products, services, policies, practices, operations, employees, sales representatives, agents, officers, members, managers or directors. Similarly, during the period set forth in the preceding sentence,
Parent shall not and shall not authorize or encourage any members of its Board of Directors or employees to directly or indirectly, make or cause to be made to any person any disparaging, derogatory or other negative statement about Executive,
including the performance of his duties on behalf of the Company or the circumstances surrounding his separation from employment. 
 (g) I
REPRESENT AND WARRANT THAT THE KNOWLEDGE, SKILLS AND ABILITIES I POSSESS ARE SUFFICIENT TO PERMIT ME, IN THE EVENT OF TERMINATION OF MY EMPLOYMENT WITH PARENT FOR ANY REASON, TO EARN, FOR A PERIOD OF UP TO TWENTY-FOUR (24) MONTHS FROM SUCH
TERMINATION, A LIVELIHOOD SATISFACTORY TO ME WITHOUT VIOLATING ANY PROVISION OF SECTION 3 HEREOF, FOR EXAMPLE BY USING SUCH KNOWLEDGE, SKILLS AND ABILITIES, OR SOME OF THEM, IN THE SERVICE OF A PERSON OR ENTITY WHO OR WHICH DOES NOT COMPETE WITH
PARENT AS DESCRIBED HEREIN. 
 4. PROPRIETARY INFORMATION. 

(a) I agree that all information and know-how, whether or not in writing, of a private, secret or confidential nature concerning the Company,
Parent or any of their affiliates or their respective businesses, financial affairs or operations (collectively, “PROPRIETARY INFORMATION”) is and shall be the exclusive property of the Company, Parent or any of their affiliates, as the
case may be. By way of illustration, but not limitation, Proprietary Information may include inventions, products, manufacturing and other processes, methods, techniques, formulas, compositions, compounds, projects, developments, plans, research
data, financial data, personnel data, computer programs, and customer and supplier lists. I will not disclose any Proprietary Information to others outside the Company, Parent or any of their affiliates, provided that my obligation not to disclose
shall not apply to any information that (i) has become generally available to the public other than as a result of a breach by Executive of his obligations hereunder, (ii) may be required or appropriate in response to any summons or subpoena or in
connection with any litigation, or investigation or review by any governmental agency or authority and (iii) must be disclosed in order to comply with any law, order, regulation or ruling applicable to Executive. I will not use any Proprietary
Information for any purposes other than my work for the Company, Parent or any of their affiliates, without prior written approval by the Board of Directors of Parent, either during or after my providing services. If I have any questions as to what
constitutes Proprietary Information, I will consult with the Board of Directors of Parent or an individual designated by the Board of Directors for this purpose. 

  









 Page 7 of 10 
  

 (b) I agree that all files, letters, memoranda, reports, records, data, sketches, drawings,
program listings, or other written, photographic, or other tangible material containing Proprietary Information, whether created by me or others, which shall come into my custody or possession, shall be and are the exclusive property of the Company,
Parent or any of their affiliates, as the case may be, to be used by me only in the performance of my duties for Parent. All such records or copies thereof and all tangible property of the Company, Parent or any of their affiliates in my custody or
possession shall be delivered to Parent within ten (10) calendar days from the earlier of (i) a request by Parent or (ii) termination of my providing services to Parent. After such delivery, I shall not retain any such records or copies thereof or
any such tangible property. 
 (c) I agree that my obligation not to disclose or to use information, know-how and records of the types set
forth in paragraphs (a) and (b) above, and my obligation to return records and tangible property, set forth in paragraph (b) above, also extends to such types of information, know-how, records and tangible property of customers of the Company,
Parent or any of their affiliates or suppliers to the Company, Parent or any of their affiliates or other third parties who may have disclosed or entrusted the same to Parent or to me in the course of Parent’s business with an expectation or
understanding that such information was to be maintained as confidential. 
 5. DEVELOPMENTS. 

(a) I will make full and prompt disclosure to Parent of all inventions, improvements, discoveries, methods, developments, products, processes,
techniques, formulas, compositions, compounds, software, works of authorship and all ideas for trademarks, trade-names and the like, related in any way to the Parent’s current, planned or potential products or services, whether patentable or
not and whether copyrightable or not, which are created, made, conceived or reduced to practice by me or under my direction or jointly with others during my employment by Parent, whether or not during normal working hours or on the premises of
Parent (all of which are collectively referred to in this Agreement as “DEVELOPMENTS”). 
 (b) Except as hereinafter provided, I
agree to assign and do hereby assign to Parent (or any person or entity designated by Parent) all my right, title and interest in and to all Developments and all related patents, patent applications, copyrights and copyright applications. I
expressly agree that all of my Developments capable of protection under copyright laws shall be deemed and are works made for hire with the understanding that Parent shall own all of the exclusive rights to such developments under the United States
Copyright Act and all international copyright conventions and foreign laws, and any successor laws thereto. 
 (c) I agree to cooperate
fully with Parent, both during and after my employment with Parent, with respect to the procurement, maintenance and enforcement of copyrights and patents (both in the United States and foreign countries) relating to Developments. I shall sign all
papers, including, without limitation, copyright applications, patent applications, trademark or service mark applications, declarations, oaths, formal assignments, assignment of priority rights, and powers of attorney, which Parent may deem
necessary or desirable in order to protect its rights and interests in any Development.

 6. CURRENT EMPLOYMENT; NO CONTRARY AGREEMENTS. 

I hereby represent that I am not bound by the terms of any agreement with any current or previous employer or other party to refrain from
using or disclosing any trade secret or confidential or Proprietary Information in the course of my employment with Parent or to refrain from competing, directly or indirectly, with the business of such previous employer or any other party. I
further represent that, and agree that, in the performance of my duties as a provider of services to Parent, I will not breach any agreement to keep in confidence Proprietary Information, knowledge or data acquired by me in confidence or in trust
prior to my employment with Parent, and I will not disclose to Parent or induce Parent to use any confidential or proprietary information or material belonging to any previous employer or others. I represent and warrant to Parent that I am not now
under any obligation of a contractual nature to any person, firm or corporation which is inconsistent or in conflict with this Agreement. 

7. INJUNCTIVE RELIEF. 
 The
restrictions contained herein are necessary for the protection of the business and goodwill of the Company, Parent and their affiliates and are considered by me to be reasonable for such purposes. I understand and agree that Parent will suffer
irreparable harm in the event that I breach any of my obligations under this Agreement and that monetary damages will be inadequate to compensate Parent for such breach. Accordingly, I agree that, in the event of a breach or threatened breach by me
of any of the provisions of this Agreement, Parent, in addition to and not in limitation of any other rights, remedies or damages available to Parent at law or in equity, shall be entitled to a permanent injunction in order to prevent or to restrain
any such breach by me, or by my partners, agents, representatives, employers, employees and/or any and all persons directly or indirectly acting for or with me. 

8. ACCOUNTING FOR PROFITS. 
 I
covenant and agree that, if I shall violate any of my covenants or agreements under this Agreement, Parent, at its own expense, shall be entitled to an accounting and repayment of all profits, compensation, commissions, remunerations or benefits
which I directly or indirectly have realized and/or may realize as a result of, growing out of or in connection with any such violation; such remedy shall be in addition to and not in limitation of any injunctive relief or other rights or remedies
to which Parent is or may be entitled at law, in equity or under this Agreement. 
 9. NO EMPLOYMENT CONTRACT. 

I understand that this Agreement does not constitute a contract of employment and does not imply that my employment will continue for any
period of time. 
 10. ENFORCEABILITY AND SCOPE. 

In the event that any Section of this Agreement, or any provision of any such Section, shall for any reason be held to be wholly invalid,
illegal or unenforceable, such invalidity, illegality, or unenforceability shall not affect any other Section hereof, or any other provision of an affected Section, and this Agreement shall be construed as if, and enforced as fully as if, such


  









 Page 9 of 10 
  

 
invalid, illegal or unenforceable Section or provision had never been contained herein. In the event any Section, or any provision thereof, is found to be partially invalid, illegal or
unenforceable (on the ground, for example, that it is excessive in scope), then such Section or provision shall be enforced to the extent not invalid, illegal or unenforceable, and its partial invalidity, illegality or unenforceability shall not
affect any other Section or provision of this Agreement. If any restriction set forth in Section 3 above is found by a court of competent jurisdiction to be unenforceable because it extends for too long a period of time, over too great a range of
activities or in too broad a geographic area, such restriction shall be interpreted to extend only over the maximum period of time, maximum range of activities or maximum geographic area as to which it may be deemed to be enforceable. 

11. GENERAL. 
 (a) This
Agreement supersedes all prior agreements, written or oral, between me and Parent relating to the subject matter of this Agreement, except for the the Change in Control Agreement and the Severance Agreement, which are referenced herein. This
Agreement may not be modified, changed or discharged in whole or in part, except by an agreement in writing signed by me and Parent. I agree that any change or changes in my duties, salary or compensation after the signing of this Agreement shall
not affect the validity or scope of this Agreement. 
 (b) This Agreement will be binding upon my heirs, executors and administrators and
will inure to the benefit of and be binding upon Parent and its successors and assigns. 
 (c) No delay or omission by Parent in exercising
any right under this Agreement will operate as a waiver of that or any other right. A waiver or consent given by Parent on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any other
occasion. 
 (d) I expressly consent to be bound by the provisions of this Agreement for the benefit of the Company, Parent or any of their
affiliates to whose employ or other service providing arrangement I may be transferred without the necessity that this Agreement be re-signed at the time of such transfer.

 Exhibit C 

RELEASE OF CLAIMS 
 FOR AND IN
CONSIDERATION OF the benefits to be provided me in connection with the termination of my employment, as set forth in the Employment Agreement between myself and pSivida Corp. (the “Company”) dated as of October 31, 2008 (the
“Agreement”), which benefits are subject to my signing of this Release of Claims and to which I am not otherwise entitled, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, I, on my
own behalf and on behalf of my heirs, executors, administrators, beneficiaries, representatives and assigns, and all others connected with me, hereby release and forever discharge the Company, the Subsidiary (as defined in the Agreement), its other
subsidiaries and other affiliates and all of their respective past, present and future officers, directors, trustees, shareholders, employees, agents, general and limited partners, members, managers, joint venturers, representatives, successors and
assigns, and all others connected with any of them, both individually and in their official capacities, from any and all causes of action, rights and claims of any type or description, known or unknown, which I have had in the past, now have, or
might now have, through the date of my signing of this Release of Claims, in any way resulting from, arising out of or connected with my employment by the Company or the Subsidiary or any of its other subsidiaries or other affiliates or the
termination of that employment or pursuant to any federal, state or local law, regulation or other requirement (including without limitation Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act, the Americans with
Disabilities Act, and the fair employment practices laws of the state or states in which I have been employed by the Company or any of the subsidiaries or other affiliates, each as amended from time to time). 

Excluded from the scope of this Release of Claims is (i) any claim arising under the terms of the Agreement, (ii) any right of indemnification or contribution
that I have pursuant to the Certificate of Incorporation, Constitution, By-Laws or other governing documents of the Company or the Subsidiary, and (iii) any claim that I have related to any failure by pSivida Limited to register “Registrable
Securities” pursuant to Section 4 of the Registration Rights Agreement, dated as of December 30, 2005, by and among pSivida Limited and certain securityholders of Control Delivery Systems, Inc. 

In signing this Release of Claims, I acknowledge my understanding that I may not sign it prior to the termination of my employment, but that I may consider
the terms of this Release of Claims for up to twenty-one (21) days (or such longer period as the Company may specify) from the later of the date my employment with the Company terminates or the date I receive this Release of Claims. I also
acknowledge that I am advised by the Company and its affiliates to seek the advice of an attorney prior to signing this Release of Claims; that I have had sufficient time to consider this Release of Claims and to consult with an attorney, if I
wished to do so, or to consult with any other person of my choosing before signing; and that I am signing this Release of Claims voluntarily and with a full understanding of its terms. 

  








 I further acknowledge that, in signing this Release of Claims, I have not relied on any promises or
representations, express or implied, that are not set forth expressly in the Agreement. I understand that I may revoke this Release of Claims at any time within seven (7) days of the date of my signing by written notice to the General Counsel of the
Company and that this Release of Claims will take effect only upon the expiration of such seven-day revocation period and only if I have not timely revoked it. 

Intending to be legally bound, I have signed this Release of Claims under seal as of the date written below.
