During the term of this Agreement and for a period of one (1) year following the Termination Date, Executive shall not, without the express written consent of the Company, directly or indirectly: (i) engage in any business or other activity conducted or operated in the United States, Canada and internationally which is competitive with the Company in the products or services being published, manufactured, marketed, distributed, or being actively developed by the Company as evidenced by the Company’s books and records as of the Termination Date (the “ Business ”); (ii) be or become a stockholder, partner, owner, officer, director or employee or agent of, or a consultant to or give financial or other assistance to, any person or entity engaged in the Business; (iii) seek in competition with the business of the Company to procure orders from or do business with any customer of the Company; (iv) solicit, or contact with a view to the engagement or employment by any person or entity of, any person who is an employee of the Company; (v) seek to contract with or engage (in such a way as to adversely affect or interfere with the business of the Company) any person or entity who has been contracted with or engaged to manufacture, assemble, supply or deliver products, goods, materials or services to the Company; or (vi) engage in or participate in any effort or act to induce any of the customers, associates, consultants, or employees of the Company to take any action which might be disadvantageous to the Company; provided , however , that nothing herein shall prohibit Executive and his affiliates from owning, as passive investors, in the aggregate not more than 5% of the outstanding publicly traded stock of any corporation so engaged; and provided , further , following the Termination Date, that Executive shall not be prohibited from (1) making any investment in, being or becoming a partner, owner, officer, director or employee or agent of, or consultant to, or give financial or other assistance to, any business enterprise (including, without limitation, any investment or venture capital fund or investment bank) that makes or has made any investment in or that provides advisory, financing or underwriting services to any Person or entity engaged in the Business provided that Executive does not render services (whether as an employee, consultant, advisor or otherwise) to the division or portion of such

13

person or entity engaged in the Business or (2) rendering services (including under (1) above) to an entity conducting its business operations or providing services in the Business, if such entity is diversified and Executive does not render services, directly or indirectly, to the division or portion of the entity which is conducting its business operations or providing services in the Business.

(d) Injunctive and Other Relief .

(i) Executive acknowledges and agrees that the covenants contained herein are fair and reasonable in light of the consideration paid hereunder, and that damages alone shall not be an adequate remedy for any breach by Executive of his covenants contained herein and accordingly expressly agrees that, in addition to any other remedies which Company may have, Company shall be entitled to injunctive relief in any court of competent jurisdiction for any breach or threatened breach of any such covenants by Executive. Nothing contained herein shall prevent or delay Company from seeking, in any court of competent jurisdiction, specific performance or other equitable remedies in the event of any breach or intended breach by Executive of any of its obligations hereunder.

(ii) Notwithstanding the equitable relief available to the Company, Executive, in the event of a breach of his covenants contained in Section 19 hereof, understands and agrees that the uncertainties and delay inherent in the legal process would result in a continuing breach for some period of time, and therefore, continuing injury to the Company until and unless Company can obtain such equitable relief. Therefore, in addition to such equitable relief, Company shall be entitled to monetary damages for any such period of breach until the termination of such breach, in an amount up to the amount of all monies received by Executive as a result of said breach. If Executive should use or reveal to any other person or entity any confidential information, such use or revelation would be considered a continuing violation on a daily basis for as long as such confidential information is made use of by Executive.

(iii) If any provision of Section 19 is determined to be invalid or unenforceable by reason of its duration or scope, such duration or scope, or both, shall be deemed to be reduced to a duration or scope to the extent necessary to render such provision valid and enforceable. In such event, Executive shall negotiate in good faith to provide Company with lawful and enforceable protection that is most nearly equivalent to that found to be invalid or unenforceable.

(e) Continuing Operation . Except as specifically provided in this Section 19, the termination of Executive’s employment or of this Agreement shall have no effect on the continuing operation of this Section 19.

14

(f) Company . For purposes of this Section 19, the term “Company” shall mean Integra LifeSciences Holdings Corporation and any corporation, partnership or other entity owned directly or indirectly, in whole or in part, by Integra LifeSciences Holdings Corporation

20. Miscellaneous .

(a) Amendment . No provision of this Agreement may be amended unless such amendment is signed by Executive and such officer as may be specifically designated by the Board to sign on the Company’s behalf.

(b) Section 409A .

(i) This Agreement shall be interpreted to avoid any penalty sanctions under Section 409A of the Code. If any payment or benefit cannot be provided or made at the time specified herein without incurring sanctions under Section 409A, then such benefit or payment shall be provided in full at the earliest time thereafter when such sanctions will not be imposed. All payments to be made upon a termination of employment under this Agreement may only be made upon a ‘separation from service’ under Section 409A of the Code. For purposes of Section 409A of the Code, each payment made under this Agreement shall be treated as a separate payment. In no event may Executive, directly or indirectly, designate the calendar year of payment.

(ii) To the extent that any payments or reimbursements provided to Executive under this Agreement are deemed to constitute compensation to which Treasury Regulation Section 1.409A-3(i)(1)(iv) would apply, such payments or reimbursements shall be made or provided in accordance with the requirements of Section 409A, including, where applicable, the requirement that (A) any reimbursement is for expenses incurred during Executive’s lifetime (or during a shorter period of time specified in this Agreement), (B) the amount of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other calendar year, (C) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred, and (D) the right to reimbursement is not subject to liquidation or exchange for another benefit. If expenses are incurred in connection with litigation, any reimbursements under the Agreement shall be paid not later than the end of the calendar year following the year in which the litigation is resolved.

(c) Nature of Obligations . Nothing contained herein shall create or require the Company to create a trust of any kind to fund any benefits which may be payable hereunder, and to the extent that Executive acquires a right to receive benefits from the Company hereunder, such right shall be no greater than the right of any unsecured general creditor of the Company.

15

(d) Prior Employment . Executive represents and warrants that his acceptance of employment with the Company has not breached, and the performance of his duties hereunder will not breach, any duty owed by him to any prior employer or other person. Executive further represents and warrants to the Company that (i) the performance of his obligations hereunder will not violate any agreement between him and any other person, firm, organization or other entity, (ii) he is not bound by the terms of any agreement with any previous employer or other party to refrain from competing, directly or indirectly, with the business of such previous employer or other party that would be violated by him entering into this Agreement and/or providing services to the Company pursuant to the terms of this Agreement, and (iii) Executive’s performance of his duties under this Agreement will not require him to, and he shall not, rely on in the performance of his duties or disclose to the Company or any other person or entity or induce the Company in any way to use or rely on any trade secret or other confidential or proprietary information or material belonging to any previous employer of Executive.

(e) Headings . The Section headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation or this Agreement. In the event of a conflict between a heading and the content of a Section, the content of the Section shall control.

(f) Recoupment . To the extent required by applicable law or any applicable securities exchange listing standards, any amounts paid or payable under this Agreement (including, without limitation, amounts paid prior to the effectiveness of such law or listing standards) shall be subject to forfeiture, repayment or recapture to the extent required by such applicable law or listing standard.

(g) Gender and Number . Whenever used in this Agreement, a masculine pronoun is deemed to include the feminine and a neuter pronoun is deemed to include both the masculine and the feminine, unless the context clearly indicates otherwise. The singular form, whenever used herein, shall mean or include the plural form where applicable.

(h) Severability . If any provision of this Agreement or the application thereof to any person or circumstance shall be invalid or unenforceable under any applicable law, such event shall not affect or render invalid or unenforceable any other provision of this Agreement and shall not affect the application of any provision to other persons or circumstances.

(i) Binding Effect . This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors, permitted assigns, heirs, executors and administrators.

(j) Notice . For purposes of this Agreement, notices and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given if hand-delivered, sent by documented overnight

EXHIBIT A

CONTRACT STOCK/RESTRICTED UNITS AGREEMENT

[ Form for Arduini Annual Contract Stock Grant ]

INTEGRA LIFESCIENCES HOLDINGS CORPORATION

CONTRACT STOCK / RESTRICTED UNITS AGREEMENT

Pursuant to

2003 EQUITY INCENTIVE PLAN

AGREEMENT, dated as of             , 20    , by and between Integra LifeSciences Holdings Corporation, a Delaware corporation (the “ Company ”), and Peter J. Arduini (the “ Executive ”).

WHEREAS, the Company and Executive have previously entered into that certain Amended and Restated Employment Agreement dated as of December 20, 2011 (the “ Employment Agreement ”);

WHEREAS, the Company maintains the Integra LifeSciences Holdings Corporation Second Amended and Restated 2003 Equity Incentive Plan (the “ 2003 Plan ”), the terms of which are hereby incorporated by reference and made part of this Agreement;

WHEREAS, the 2003 Plan provides for the award of Contract Stock on the terms and conditions set forth therein; and

WHEREAS, the Committee has determined that, as an inducement to the Executive to enter into or remain in the service of the Company, it would be to the advantage and in the best interest of the Company and its stockholders to grant to Executive an aggregate of [            ] (            ) shares of Contract Stock under the 2003 Plan in the form of restricted units (the “ Units ”) representing the right to receive an equal number of shares of common stock of the Company, par value $.01 per share (“ Common Stock ”), on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and for other good and valuable consideration the legal sufficiency of which is hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

1. Definitions . Capitalized terms not otherwise defined herein shall have the meanings set forth in the Employment Agreement or the 2003 Plan, as applicable, unless otherwise indicated.

2. Grant of Units . Executive is hereby granted, as of             , 20     (the “ Grant Date ”), deferred compensation in the form of [            ] (                    ) Units pursuant to the terms of this Agreement and the 2003 Plan. The Executive’s right to receive the

shares of Common Stock underlying the Units shall be subject to forfeiture as provided in Section 4 of this Agreement.

3. Vesting .

(a) Subject to paragraph (b) and Section 4 below, the Units shall vest in cumulative installments as follows:

(i) One-third (  ¹ / 3 ) of the Units shall vest on the first anniversary of the [Grant Date];

(ii) One-third (  ¹ / 3 ) of the Units shall vest on the second anniversary of the [Grant Date]; and

(iii) One-third (  ¹ / 3 ) of the Units shall vest on the third anniversary of the [Grant Date];

(b) One hundred percent (100%) of the then outstanding Units shall vest in the event that:

(i) Executive incurs a Termination of Service (as defined below) (1) by reason of the Executive’s “Disability” (as defined in Section 1 of the Employment Agreement), or (2) by reason of the Executive’s death; or

(ii) a “Change in Control” (as defined in the Employment Agreement) occurs prior to the Executive’s Termination of Service.

(c) For purposes of this Agreement, “ Termination of Service ” shall mean the time when the Executive ceases to provide services to the Company and its Related Corporations and Affiliates as an employee or Associate for any reason with or without cause, including, but not by way of limitation, a termination by resignation, discharge, death, or disability. A Termination of Service shall not include a termination where the Executive is simultaneously reemployed by, or remains employed by, or continues to provide services to, the Company and/or one or more of its Related Corporations and Affiliates or a successor entity thereto.

4. Forfeiture of Units . Immediately upon a Termination of Service for any reason other than the Executive’s death or Disability, the Executive shall forfeit any and all Units which have not vested or do not vest on or prior to such termination, and the Executive’s rights in any such Units which are not so vested shall terminate, lapse and expire (including the Executive’s right to receive the shares underlying such Units).

5. Dividend Equivalents . Executive shall be entitled to receive, with respect to all outstanding vested Units (as such Units may be adjusted under Section 8), dividend equivalent amounts equal to the regular quarterly cash dividend payable to holders of Common Stock (to the extent regular quarterly cash dividends are paid) as if Executive were an actual shareholder with respect to the number of shares of Common Stock equal to his outstanding vested Units. Such dividend equivalent amounts shall be aggregated on a quarterly basis while the Units are outstanding and paid to Executive within thirty (30) days following the first business day that occurs immediately following the 6-month period after the date of Executive’s “separation from service” from the Company (within the meaning of Section 409A(a)(2)(A)(i) of the Internal Revenue Code of 1986, as amended (the “ Code ”) and its corresponding regulations) (a “ Separation from Service ”). For the avoidance of doubt, such dividend equivalent amounts shall only be paid with respect to Units that are vested as of the applicable dividend payment date, and

2

Executive shall not be entitled to receive any dividend equivalent amounts with respect to Units that are not vested as of such dividend payment date. The dividend equivalents and any amounts that may become payable in respect thereof shall be treated separately from the Units and the rights arising in connection therewith for purposes of the designation of time and form of payments required by Code Section 409A.

6. Payment of Units .

(a) The shares of Common Stock underlying Units which are then vested under Section 3(a) or 3(b) (the “ Unit Shares ”) shall be paid out to Executive within thirty (30) days following the first business day that occurs immediately following the 6-month period after the date of Executive’s Separation from Service.

(b) All payments of Unit Shares shall be made by the Company in the form of whole shares of Common Stock, and any fractional share shall be distributed in cash in an amount equal to the value of such fractional share determined based on the Fair Market Value (as defined in the 2003 Plan) as of the date immediately prior to such distribution.

(c) Any Unit Shares delivered shall be deposited in an account designated by Executive and maintained at a brokerage house selected by Executive. Any such Unit Shares shall be duly authorized, fully paid and non-assessable shares, listed with NASDAQ or the principal United States securities exchange on which the Common Stock is admitted to trading and, so long as the Company is required to file reports under Section 13 or 15(d) of the Securities Exchange Act of 1934, registered on a Form S-8 registration statement maintained by the Company, if registration is requested by Executive.

(d) Except as otherwise provided in this Agreement, Executive shall not be deemed to be a holder of any Common Stock pursuant to a Unit until the date of the issuance of a certificate to him for such shares and, except as otherwise provided in this Agreement, Executive shall not have any rights to dividends or any other rights of a shareholder with respect to the shares of Common Stock covered by a Unit until such shares of Common Stock have been issued to him, which issuance shall not be unreasonably delayed.

(e) The Company shall be entitled to withhold in cash, shares or deduction from other compensation payable to the Executive any sums required by federal, state or local tax law to be withheld with respect to the grant, vesting, distribution or payment of the Units or the Unit Shares. In satisfaction of the foregoing requirement with respect to the grant, vesting, distribution or payment of the Units or Unit Shares, to the extent permitted by Section 409A of the Code, including Treas. Reg. Section 1.409A-3(j)(4)(vi), the Company shall withhold shares of Common Stock otherwise issuable upon payment of the Units having a Fair Market Value equal to the sums required to be withheld. Subject to the following sentence, the number of shares of Common Stock which shall be so withheld in order to satisfy the Executive’s federal, state and local withholding tax liabilities with respect to the grant, vesting, distribution or payment of the Units or Unit Shares shall be limited to the number of shares which have a Fair

3

Market Value on the date of withholding equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state and local tax purposes that are applicable to such supplemental taxable income. In the event that the number of shares of Common Stock having a Fair Market Value equal to the sums required to be withheld is not a whole number of shares, the number of shares so withheld shall be rounded up to the nearest whole share.

(f) Executive’s right to receive payment of any amounts under this Agreement shall be an unfunded entitlement and shall be an unsecured claim against the general assets of the Company.

(g) After payment in accordance with this Section 6, the Unit Shares may not be sold, transferred or otherwise disposed of by Executive for a period of five days after receipt of such shares by Executive, except that no such restrictions shall apply in the case of a Change in Control or in the event that Unit Shares are sold or withheld in order to satisfy any obligations Executive may have with respect to any applicable tax withholding requirements on vesting or receipt of Unit Shares (including, without limitation, pursuant to Section 6(e) above).

7. Representations . The Company represents and warrants that this Agreement has been authorized by all necessary action of the Company, has been approved by the Board and is a valid and binding agreement of the Company enforceable against it in accordance with its terms and that the Unit Shares will be issued pursuant to and in accordance with the 2003 Plan, will be listed with NASDAQ or the principal United States securities exchange on which the Common Stock is admitted to trading, and will be validly issued, fully paid and non-assessable shares. The Company further represents and warrants that the grant of Units under this Agreement has been approved by the Company’s Compensation Committee, that the 2003 Plan has and will have sufficient shares available to effect the distribution of the Unit Shares.

8. Changes in the Common Stock and Adjustment of Units .

(a) In the event the outstanding shares of the Common Stock shall be changed into an increased number of shares, through a share dividend or a split-up of shares, or into a decreased number of shares, through a combination of shares, then immediately after the record date for such change, the number of Units then subject to this Agreement shall be proportionately increased, in case of such share dividend or split-up of shares, or proportionately decreased, in case of such combination of shares. In the event the Company shall issue any of its shares of stock or other securities or property (other than Common Stock which is covered by the preceding sentence), in a reclassification of the Common Stock (including without limitation any such reclassification in connection with a consolidation or merger in which the Company is the continuing entity), the kind and number of Units subject to this Agreement immediately prior thereto shall be adjusted so that the Executive shall be entitled to receive the same kind and number of shares or other securities or property which the Executive would have owned or have been entitled to receive after the happening of any of the events described above, had he owned the shares of the Common Stock represented by the Units under this Agreement immediately

4

prior to the happening of such event or any record date with respect thereto, which adjustment shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.

(b) In the event the Company shall distribute to all holders of the Common Stock evidences of its indebtedness or assets (including leveraged recapitalizations with special cash distributions, but excluding regular quarterly cash dividends), then in each case the number of Units thereafter subject to this Agreement shall be determined by multiplying the number of Units theretofore subject to this Agreement by a fraction, (i) the numerator of which shall be the then current market price per share of Common Stock (as determined in paragraph (c) below) on the record date for such distribution, and (ii) the denominator of which shall be the then current market price per share of the Common Stock less the then fair value (as mutually determined in good faith by the Board and the Executive) of the portion of the assets or evidences of indebtedness so distributed applicable to a share of Common Stock. Such adjustment shall be made whenever any such distribution is made, and shall become effective on the date of distribution retroactive to the record date for the determination of shareholders entitled to receive such distribution.

(c) For the purpose of any computation under paragraph (b) of this Section 8, the current market price per share of the Common Stock at any date shall be deemed to be the average of the daily Stock Prices (as defined herein) for 15 consecutive Trading Days (as defined herein) commencing 20 Trading Days before the date of such computation. “ Stock Price ” for each Trading Day shall be the “Fair Market Value” of the Common Stock (as defined in the 2003 Plan, as in effect on the date of this Agreement) for such Trading Day. “ Trading Day ” shall be each Monday, Tuesday, Wednesday, Thursday and Friday, other than any day on which the Common Stock is not traded on the exchange or in the market which is the principal United States market for the Common Stock.

(d) For the purpose of this Section 8, the term “ Common Stock ” shall mean (i) the class of Company securities designated as the Common Stock at the date of this Agreement, or (ii) any other class of equity interest resulting from successive changes or reclassifications of such shares consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. In the event that at any time, as a result of an adjustment made pursuant to the second sentence of Section 8(a) above, the Executive shall become entitled to Units representing any shares other than the Common Stock, thereafter the number of such other shares represented by a Unit shall be subject to adjustment from time to time in a manner and on the terms as nearly equivalent as practicable to the provisions with respect to the shares contained in this Section 8, and the provisions of this Agreement with respect to the shares of Common Stock represented by the Units shall apply on like terms to any such other shares.

(e) In case of any Change in Control, consolidation of the Company, or merger of the Company with another corporation as a result of which Common Stock is converted or modified, or in case of any sale or conveyance to another corporation of the property, assets and business of the Company as an entirety or substantially as an entirety, the

5

Company shall modify the Units so as to provide the Executive with Units reflecting the kind and amount of shares and other securities and property (or cash, as applicable) that he would have owned or have been entitled to receive immediately after the happening of such Change in Control, consolidation, merger, sale or conveyance had his Units immediately prior to such action actually been shares and, if applicable, other securities of the Company represented by those Units. The provisions of this Section 8(e) shall similarly apply to successive consolidations, mergers, sales or conveyances.

(f) If the Company distributes rights or warrants to all holders of its Common Stock entitling them to purchase shares of Common Stock at a price per share less than the current market price per share on the record date for the distribution, the Company shall distribute to Executive equivalent amounts of such rights or warrants as if Executive were an actual shareholder with respect to the number of shares of Common Stock equal to his outstanding Units. Such rights or warrants shall be exercisable at the same time, on the same terms and for the same price as the rights or warrants distributed to holders of the Common Stock; provided, however, that if such rights or warrants are deemed to be deferred compensation subject to the requirements of Section 409A of the Code, such rights or warrants shall be distributed to Executive in a manner that complies with such requirements.

(g) In case any event shall occur as to which the provisions of this Section 8 are not applicable but the failure to make any adjustment would not fairly protect the rights represented by the Units in accordance with the essential intent and principles of this Section 8 then, in each such case, the Company shall make an adjustment, if any, on a basis consistent with the essential intent and principles established in this Section 8, necessary to preserve, without dilution, the rights represented by the Units. The Company will promptly notify the Executive of any such proposed adjustment.

(h) Notwithstanding anything to the contrary contained herein, the provisions of Section 8 shall not apply to, and no adjustment is required to be made in respect of, any of the following: (i) the issuance of shares of Common Stock upon the exercise of any other rights, options or warrants that entitle the holder to subscribe for or purchase such shares (it being understood that the sole adjustment pursuant to this Section 8 in respect of the issuance of shares of Common Stock upon exercise of rights, options or warrants shall be made at the time of the issuance by the Company of such rights, options or warrants, or a change in the terms thereof); (ii) the issuance of shares of Common Stock to the Company’s employees, directors or consultants pursuant to bona fide benefit plans adopted by the Company’s Board; (iii) the issuance of shares of Common Stock in a bona fide public offering pursuant to a firm commitment offering; (iv) the issuance of shares of Common Stock pursuant to any dividend reinvestment or similar plan adopted by the Company’s Board to the extent that the applicable discount from the current market price for shares issued under such plan does not exceed 5%; and (v) the issuance of shares of Common Stock in any arm’s length transaction, directly or indirectly, to any party.

(i) Notwithstanding anything in this Agreement to the contrary, in the event of a spin-off by the Company to its shareholders, Executive’s participation in such spin-off with respect to the Units and the adjustment of the Units shall be determined in an appropriate and

6

equitable manner, and it is the intention of the parties hereto that, to the extent practicable, such adjustment shall include an equity interest in the spin-off entity.

(j) In the event the parties hereto cannot agree upon an appropriate and equitable adjustment to the Units, the services of an independent investment banker mutually acceptable to Executive and the Company shall (at the sole expense of the Company) be retained to determine an appropriate and equitable adjustment, and such determination shall be binding upon the parties.

(k) Each additional Unit which results from adjustments made pursuant to this Section 8 or the 2003 Plan shall be subject to the same terms and conditions regarding vesting and forfeiture as the underlying Unit to which such additional Unit relates.

(l) Notwithstanding the foregoing, no adjustment shall be made and no action shall be taken under this Section 8 to the extent that such adjustment or action shall cause the Units to fail to comply with Section 409A of the Code or the Treasury Regulations thereunder (to the extent applicable to the Units).

9. No Right to Employment . Nothing in this Agreement shall confer upon Executive the right to remain in employ of the Company or any subsidiary of the Company.

10. Nontransferability . This Agreement shall not be assignable or transferable by the Company (other than to successors of the Company) and this Agreement and the Units shall not be assignable or transferable by the Executive otherwise than by will or by the laws of descent and distribution, and the Units may be paid out during the lifetime of the Executive only to him. More particularly, but without limiting the generality of the foregoing, the Units may not be assigned, transferred (except as provided in the preceding sentence), pledged, or hypothecated in any way (whether by operation of law or otherwise), and shall not be subject to execution, attachment or similar process. Any attempted assignment, transfer, pledge, hypothecation or other disposition of the Units contrary to the provisions of this Agreement, and any levy of any attachment or similar process upon the Units, shall be null and void and without effect.

11. Entire Agreement . This Agreement and the Employment Agreement contain all the understandings between the parties hereto pertaining to the matters referred to herein, and supersede all undertakings and agreements, whether oral or in writing, previously entered into by them with respect thereto. The Executive represents that, in executing this Agreement, he does not rely and has not relied upon any representation or statement not set forth herein made by the Company with regard to the subject matter, basis or effect of this Agreement or otherwise.

12. Amendment or Modification; Waiver . No provision of this Agreement may be amended, modified or waived unless such amendment or modification is agreed to in writing, signed by the Executive and by a duly authorized officer of the Company, and such waiver is set forth in writing and signed by the party to be charged. No waiver by any party hereto of any breach by another party hereto of any condition or provision of this Agreement to be performed

7

by such other party shall be deemed a waiver of a similar or dissimilar condition or provision at the same time, any prior time or any subsequent time.

13. Notices . Any notice to be given hereunder shall be in writing and shall be deemed given when delivered personally, sent by courier or telecopy or registered or certified mail, postage prepaid, return receipt requested, addressed to the party concerned at the address indicated below or to such other address as such party may subsequently give notice of hereunder in writing:

2. Purchase Price . The purchase price per share of the shares of Common Stock covered by the Option shall be that set forth in the attached Notice of Grant, subject to adjustment in accordance with Section 8 of the Plan. It is the determination of the Company’s Compensation Committee (the “Committee”) that on the Grant Date the per share Option exercise price was not less than the greater of one hundred percent (100%) of the fair market value of the Common Stock, or the par value thereof.

3. Term . Unless earlier terminated pursuant to any provision of this Option Agreement, this Option shall expire on the date set forth in the attached Notice of Grant (the “Expiration Date”). Notwithstanding anything herein to the contrary, this Option shall not be exercisable after the Expiration Date.

4. Exercise of Option . This Option shall vest and become exercisable with respect to 1/3 ^rd of the shares subject hereto on the first anniversary of the [Grant Date]. Thereafter, this Option shall vest and become exercisable with respect to 1/24 ^th of the remaining shares on the first business day of each following month.

Any portion of the Option that becomes exercisable in accordance with the foregoing shall remain exercisable, subject to the provisions contained in this Option Agreement, until the expiration of the term of this Option as set forth in Paragraph 3 or until other termination of the Option as set forth in this Option Agreement.

Notwithstanding anything contained herein, no portion of the Option which has not become vested and exercisable as of the Employee’s termination of employment or in connection with Employee’s termination of employment shall thereafter become vested or exercisable.

5. Method of Exercising Option . Subject to the terms and conditions of this Option Agreement, the Option may be exercised in whole or in part by written notice to the Company, at its principal office, which currently is located at 311 Enterprise Drive, Plainsboro, New Jersey 08536. Such notice shall state the election to exercise the Option, and the number of shares with respect to which it is being exercised; shall be signed by the person or persons so exercising the Option; shall, unless the Company otherwise notifies the Employee, be accompanied by the investment certificate referred to in Paragraph 6; and shall be accompanied by payment of the full Option price of such shares.

The Option price shall be paid to the Company: (i) in cash; (ii) in cash equivalent; (iii) in Common Stock of the Company, in accordance with Section 7.1(f)(ii) of the Plan (as in effect on the date of this Option Agreement); (iv) by delivering a properly executed notice of exercise of the Option, in accordance with Section 7.1(f)(iii) of the Plan (as in effect on the date of this Option Agreement); (v) in Common Stock of the Company issuable pursuant to the exercise of the Option or otherwise withheld in net settlement of the Option, in accordance with Section 7.1(f)(iv) of the Plan (as in effect on the date of this Option Agreement); or (vi) by any combination of (i)-(v).

Upon receipt of such notice and payment, the Company, as promptly as practicable, shall deliver or cause to be delivered a certificate or certificates representing the shares with respect to which the Option is so exercised. Such certificate(s) shall be registered in the name of the person or persons so exercising the Option (or, if the Option is exercised by the Employee and if the Employee so requests in the notice exercising the Option, shall be registered in the name of the Employee and the Employee’s spouse, jointly, with right of survivorship) and shall be delivered as provided above to or upon the written order of the person or persons exercising the Option. In the event the Option is exercised by any person or persons after the legal disability or death of the Employee, such notice shall be accompanied by appropriate proof of the right of such person or persons to exercise the Option. All shares that are purchased upon the exercise of the Option as provided herein shall be fully paid and not assessable by the Company.

6. Shares to be Purchased for Investment . Unless the Company has theretofore notified the Employee that a registration statement covering the shares to be acquired upon the exercise of the Option has become effective under the Securities Act of 1933 and the Company has not thereafter notified the Employee that such registration statement is no longer effective, it shall be a condition to any exercise of this Option that the shares acquired upon such exercise be acquired for investment and not with a view to distribution, and the person effecting such exercise shall submit to the Company a certificate of such investment intent, together with such other evidence supporting the same as the Company may request. The Company shall be entitled to delay the transferability of the shares issued upon any such exercise to the extent necessary to avoid a risk of violation of the Securities Act of 1933 (or of any rules or regulations promulgated thereunder) or of any state laws or regulations. Such restrictions may, at the option of the Company, be noted or set forth in full on the share certificates.

7. Non-Transferability of Option . This Option is not assignable or transferable, in whole or in part, by the Employee other than by will or by the laws of descent and distribution,

2

and during the lifetime of the Employee the Option shall be exercisable only by the Employee or by his or her guardian or legal representative.

8. Termination of Employment . If the Employee’s employment with the Company and all Related Corporations is terminated for any reason other than death or disability prior to the Expiration Date, this Option may be exercised, to the extent of the number of shares with respect to which the Employee could have exercised it on the date of such termination of employment, or to any greater extent permitted by the Committee, by the Employee at any time prior to the earlier of:

9. Disability . If the Employee incurs a disability, as defined in the Plan, during his or her employment with the Company and Related Corporations and, prior to the Expiration Date, the Employee’s employment is terminated as a consequence of such disability, this Option may be exercised, to the extent of the number of shares with respect to which the Employee could have exercised it on the date of such termination of employment, or to any greater extent permitted by the Committee in its discretion, by the Employee, or in the event of the Employee’s legal disability, by the Employee’s legal representative, at any time prior to the earlier of:

10. Death . If the Employee dies during his or her employment with the Company and Related Corporations and prior to the Expiration Date, or if the Employee’s employment is terminated for any reason (as described in Paragraphs 8 or 9 above) and the Employee dies following his or her termination of employment but prior to the earliest of the Expiration Date or the expiration of the period determined under Paragraph 8 or 9 above, this Option may be exercised, to the extent of the number of shares with respect to which the Employee could have exercised it on the date of his or her death, or to any greater extent permitted by the Committee, by the Employee’s estate, personal representative or beneficiary who acquired the right to exercise this Option by bequest or inheritance or by reason of the Employee’s death, at any time prior to the earlier of:

11. Withholding of Taxes . The obligation of the Company to deliver shares of Common Stock upon the exercise of the Option shall be subject to applicable federal, state and local tax withholding requirements. If the exercise of any Option is subject to the withholding requirements of applicable federal, state or local tax laws, the Committee, in its discretion, may permit the Employee, subject to the provisions of the Plan and such additional withholding rules (the “Withholding Rules”) as shall be adopted by the Committee, to satisfy the withholding tax, in whole or in part, by electing to have the Company withhold (or by returning to the Company)

3

shares of Common Stock, which shares shall be valued, for this purpose, at their fair market value on the date of exercise of the Option (or, if later, the date on which the Employee recognizes ordinary income with respect to such exercise). An election to use shares of Common Stock to satisfy tax withholding requirements must be made in compliance with and subject to the Withholding Rules. The Committee may not withhold shares in excess of the number necessary to satisfy the minimum tax withholding requirements.

12. Construction . Except as would be in conflict with any specific provision herein, this Option Agreement is made under and subject to the provisions of the Plan as in effect on the Grant Date and, except as would conflict with the provisions of this Option Agreement, all of the provisions of the Plan as in effect on the Grant Date are hereby incorporated herein as provisions of this Option Agreement. Notwithstanding the foregoing, provisions of this Option Agreement that conflict with the Plan will be given effect only to the extent they do not exceed the Committee’s discretion under the Plan.

13. Governing Law . This Non-Qualified Stock Option Agreement shall be governed by applicable federal law and otherwise by the laws of the State of Delaware.

INTEGRA LIFESCIENCES HOLDINGS CORPORATION

CONTRACT STOCK AGREEMENT

Pursuant to

2003 EQUITY INCENTIVE PLAN

AGREEMENT, dated as of                     , 20    , by and between Integra LifeSciences Holdings Corporation, a Delaware corporation (the “ Company ”), and Peter J. Arduini (the “ Executive ”).

WHEREAS, the Company and Executive have previously entered into that certain Amended and Restated Employment Agreement dated as of December 20, 2011 (the “ Employment Agreement ”);

WHEREAS, the Company maintains the Integra LifeSciences Holdings Corporation Second Amended and Restated 2003 Equity Incentive Plan (the “ 2003 Plan ”), the terms of which are hereby incorporated by reference and made part of this Agreement;

WHEREAS, the 2003 Plan provides for the award of Contract Stock on the terms and conditions set forth therein; and

WHEREAS, the Committee has determined that, as an inducement to the Executive to enter into or remain in the service of the Company, it would be to the advantage and in the best interest of the Company and its stockholders to grant to Executive an aggregate of [                    ] (                ) shares of Contract Stock under the 2003 Plan in the form of fully vested units (the “ Units ”) representing the right to receive an equal number of shares of common stock of the Company, par value $.01 per share (“ Common Stock ”), on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and for other good and valuable consideration the legal sufficiency of which is hereby acknowledged, the parties hereto, intending to be legally bound hereby, agree as follows:

1. Definitions . Capitalized terms not otherwise defined herein shall have the meanings set forth in the Employment Agreement or the 2003 Plan, as applicable, unless otherwise indicated.

2. Grant of Units . Executive is hereby granted, as of [                        ], deferred compensation in the form of [                    ] (                                        ) fully vested Units pursuant to the terms of this Agreement and the 2003 Plan.

3. Dividend Equivalents . Executive shall be entitled to receive, with respect to all outstanding Units (as such Units may be adjusted under Section 6), dividend equivalent amounts

equal to the regular quarterly cash dividend payable to holders of Common Stock (to the extent regular quarterly cash dividends are paid) as if Executive were an actual shareholder with respect to the number of shares of Common Stock equal to his outstanding Units. Such dividend equivalent amounts shall be aggregated on a quarterly basis while the Units are outstanding and paid to Executive within thirty (30) days following the first business day that occurs immediately following the 6-month period after the date of Executive’s “separation from service” from the Company (within the meaning of Section 409A(a)(2)(A)(i) of the Internal Revenue Code of 1986, as amended (the “ Code ”) and its corresponding regulations) (a “ Separation from Service ”). The dividend equivalents and any amounts that may become payable in respect thereof shall be treated separately from the Units and the rights arising in connection therewith for purposes of the designation of time and form of payments required by Code Section 409A.

4. Payment of Units .

(a) The shares of Common Stock underlying the Units (the “ Unit Shares ”) shall be paid out to Executive within thirty (30) days following the first business day that occurs immediately following the 6-month period after the date of Executive’s Separation from Service.

(b) All payments of Unit Shares shall be made by the Company in the form of whole shares of Common Stock, and any fractional share shall be distributed in cash in an amount equal to the value of such fractional share determined based on the Fair Market Value (as defined in the 2003 Plan) as of the date immediately prior to such distribution.

(c) Any Unit Shares delivered shall be deposited in an account designated by Executive and maintained at a brokerage house selected by Executive. Any such Unit Shares shall be duly authorized, fully paid and non-assessable shares, listed with NASDAQ or the principal United States securities exchange on which the Common Stock is admitted to trading and, so long as the Company is required to file reports under Section 13 or 15(d) of the Securities Exchange Act of 1934, registered on a Form S-8 registration statement maintained by the Company, if registration is requested by Executive.

(d) Except as otherwise provided in this Agreement, Executive shall not be deemed to be a holder of any Common Stock pursuant to a Unit until the date of the issuance of a certificate to him for such shares and, except as otherwise provided in this Agreement, Executive shall not have any rights to dividends or any other rights of a shareholder with respect to the shares of Common Stock covered by a Unit until such shares of Common Stock have been issued to him, which issuance shall not be unreasonably delayed.

(e) The Company shall be entitled to withhold in cash, shares or deduction from other compensation payable to the Executive any sums required by federal, state or local tax law to be withheld with respect to the grant, vesting, distribution or payment of the Units or the Unit Shares. In satisfaction of the foregoing requirement with respect to the grant, vesting, distribution or payment of the Units or Unit Shares, to the extent permitted by Section 409A of the Code, including Treas. Reg. Section 1.409A-3(j)(4)(vi), the Company shall withhold shares of Common Stock otherwise issuable upon payment of the Units having a Fair Market Value equal to the sums required to be withheld. Subject to the following sentence, the number of

2

shares of Common Stock which shall be so withheld in order to satisfy the Executive’s federal, state and local withholding tax liabilities with respect to the grant, vesting, distribution or payment of the Units or Unit Shares shall be limited to the number of shares which have a Fair Market Value on the date of withholding equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state and local tax purposes that are applicable to such supplemental taxable income. In the event that the number of shares of Common Stock having a Fair Market Value equal to the sums required to be withheld is not a whole number of shares, the number of shares so withheld shall be rounded up to the nearest whole share.

(f) Executive’s right to receive payment of any amounts under this Agreement shall be an unfunded entitlement and shall be an unsecured claim against the general assets of the Company.

(g) After payment in accordance with this Section 4, the Unit Shares may not be sold, transferred or otherwise disposed of by Executive for a period of five days after receipt of such shares by Executive, except that no such restrictions shall apply in the case of a Change in Control (as defined in the Employment Agreement) or in the event that Unit Shares are sold or withheld in order to satisfy any obligations Executive may have with respect to any applicable tax withholding requirements on vesting or receipt of Unit Shares (including, without limitation, pursuant to Section 4(e) above).

5. Representations . The Company represents and warrants that this Agreement has been authorized by all necessary action of the Company, has been approved by the Board and is a valid and binding agreement of the Company enforceable against it in accordance with its terms and that the Unit Shares will be issued pursuant to and in accordance with the 2003 Plan, will be listed with NASDAQ or the principal United States securities exchange on which the Common Stock is admitted to trading, and will be validly issued, fully paid and non-assessable shares. The Company further represents and warrants that the grant of Units under this Agreement has been approved by the Company’s Compensation Committee, that the 2003 Plan has and will have sufficient shares available to effect the distribution of the Unit Shares.

6. Changes in the Common Stock and Adjustment of Units .

(a) In the event the outstanding shares of the Common Stock shall be changed into an increased number of shares, through a share dividend or a split-up of shares, or into a decreased number of shares, through a combination of shares, then immediately after the record date for such change, the number of Units then subject to this Agreement shall be proportionately increased, in case of such share dividend or split-up of shares, or proportionately decreased, in case of such combination of shares. In the event the Company shall issue any of its shares of stock or other securities or property (other than Common Stock which is covered by the preceding sentence), in a reclassification of the Common Stock (including without limitation any such reclassification in connection with a consolidation or merger in which the Company is the continuing entity), the kind and number of Units subject to this Agreement immediately prior thereto shall be adjusted so that the Executive shall be entitled to receive the same kind and number of shares or other securities or property which the Executive would have owned or have

3

been entitled to receive after the happening of any of the events described above, had he owned the shares of the Common Stock represented by the Units under this Agreement immediately prior to the happening of such event or any record date with respect thereto, which adjustment shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event.

(b) In the event the Company shall distribute to all holders of the Common Stock evidences of its indebtedness or assets (including leveraged recapitalizations with special cash distributions, but excluding regular quarterly cash dividends), then in each case the number of Units thereafter subject to this Agreement shall be determined by multiplying the number of Units theretofore subject to this Agreement by a fraction, (i) the numerator of which shall be the then current market price per share of Common Stock (as determined in paragraph (c) below) on the record date for such distribution, and (ii) the denominator of which shall be the then current market price per share of the Common Stock less the then fair value (as mutually determined in good faith by the Board and the Executive) of the portion of the assets or evidences of indebtedness so distributed applicable to a share of Common Stock. Such adjustment shall be made whenever any such distribution is made, and shall become effective on the date of distribution retroactive to the record date for the determination of shareholders entitled to receive such distribution.

(c) For the purpose of any computation under paragraph (b) of this Section 6, the current market price per share of the Common Stock at any date shall be deemed to be the average of the daily Stock Prices (as defined herein) for 15 consecutive Trading Days (as defined herein) commencing 20 Trading Days before the date of such computation. “ Stock Price ” for each Trading Day shall be the “Fair Market Value” of the Common Stock (as defined in the 2003 Plan, as in effect on the date of this Agreement) for such Trading Day. “ Trading Day ” shall be each Monday, Tuesday, Wednesday, Thursday and Friday, other than any day on which the Common Stock is not traded on the exchange or in the market which is the principal United States market for the Common Stock.

(d) For the purpose of this Section 6, the term “ Common Stock ” shall mean (i) the class of Company securities designated as the Common Stock at the date of this Agreement, or (ii) any other class of equity interest resulting from successive changes or reclassifications of such shares consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. In the event that at any time, as a result of an adjustment made pursuant to the second sentence of Section 6(a) above, the Executive shall become entitled to Units representing any shares other than the Common Stock, thereafter the number of such other shares represented by a Unit shall be subject to adjustment from time to time in a manner and on the terms as nearly equivalent as practicable to the provisions with respect to the shares contained in this Section 6, and the provisions of this Agreement with respect to the shares of Common Stock represented by the Units shall apply on like terms to any such other shares.

(e) In case of any Change in Control, consolidation of the Company, or merger of the Company with another corporation as a result of which Common Stock is converted or modified, or in case of any sale or conveyance to another corporation of the property, assets and business of the Company as an entirety or substantially as an entirety, the

4

Company shall modify the Units so as to provide the Executive with Units reflecting the kind and amount of shares and other securities and property (or cash, as applicable) that he would have owned or have been entitled to receive immediately after the happening of such Change in Control, consolidation, merger, sale or conveyance had his Units immediately prior to such action actually been shares and, if applicable, other securities of the Company represented by those Units. The provisions of this Section 6(e) shall similarly apply to successive consolidations, mergers, sales or conveyances.

(f) If the Company distributes rights or warrants to all holders of its Common Stock entitling them to purchase shares of Common Stock at a price per share less than the current market price per share on the record date for the distribution, the Company shall distribute to Executive equivalent amounts of such rights or warrants as if Executive were an actual shareholder with respect to the number of shares of Common Stock equal to his outstanding Units. Such rights or warrants shall be exercisable at the same time, on the same terms and for the same price as the rights or warrants distributed to holders of the Common Stock; provided, however, that if such rights or warrants are deemed to be deferred compensation subject to the requirements of Section 409A of the Code, such rights or warrants shall be distributed to Executive in a manner that complies with such requirements.

(g) In case any event shall occur as to which the provisions of this Section 6 are not applicable but the failure to make any adjustment would not fairly protect the rights represented by the Units in accordance with the essential intent and principles of this Section 6 then, in each such case, the Company shall make an adjustment, if any, on a basis consistent with the essential intent and principles established in this Section 6, necessary to preserve, without dilution, the rights represented by the Units. The Company will promptly notify the Executive of any such proposed adjustment.

(h) Notwithstanding anything to the contrary contained herein, the provisions of Section 6 shall not apply to, and no adjustment is required to be made in respect of, any of the following: (i) the issuance of shares of Common Stock upon the exercise of any other rights, options or warrants that entitle the holder to subscribe for or purchase such shares (it being understood that the sole adjustment pursuant to this Section 6 in respect of the issuance of shares of Common Stock upon exercise of rights, options or warrants shall be made at the time of the issuance by the Company of such rights, options or warrants, or a change in the terms thereof); (ii) the issuance of shares of Common Stock to the Company’s employees, directors or consultants pursuant to bona fide benefit plans adopted by the Company’s Board; (iii) the issuance of shares of Common Stock in a bona fide public offering pursuant to a firm commitment offering; (iv) the issuance of shares of Common Stock pursuant to any dividend reinvestment or similar plan adopted by the Company’s Board to the extent that the applicable discount from the current market price for shares issued under such plan does not exceed 5%; and (v) the issuance of shares of Common Stock in any arm’s length transaction, directly or indirectly, to any party.

(i) Notwithstanding anything in this Agreement to the contrary, in the event of a spin-off by the Company to its shareholders, Executive’s participation in such spin-off with respect to the Units and the adjustment of the Units shall be determined in an appropriate and equitable manner, and it is the intention of the parties hereto that, to the extent practicable, such adjustment shall include an equity interest in the spin-off entity.

5

(j) In the event the parties hereto cannot agree upon an appropriate and equitable adjustment to the Units, the services of an independent investment banker mutually acceptable to Executive and the Company shall (at the sole expense of the Company) be retained to determine an appropriate and equitable adjustment, and such determination shall be binding upon the parties.

(k) Notwithstanding the foregoing, no adjustment shall be made and no action shall be taken under this Section 6 to the extent that such adjustment or action shall cause the Units to fail to comply with Section 409A of the Code or the Treasury Regulations thereunder (to the extent applicable to the Units).

7. No Right to Employment . Nothing in this Agreement shall confer upon Executive the right to remain in employ of the Company or any subsidiary of the Company.

8. Nontransferability . This Agreement shall not be assignable or transferable by the Company (other than to successors of the Company) and this Agreement and the Units shall not be assignable or transferable by the Executive otherwise than by will or by the laws of descent and distribution, and the Units may be paid out during the lifetime of the Executive only to him. More particularly, but without limiting the generality of the foregoing, the Units may not be assigned, transferred (except as provided in the preceding sentence), pledged, or hypothecated in any way (whether by operation of law or otherwise), and shall not be subject to execution, attachment or similar process. Any attempted assignment, transfer, pledge, hypothecation or other disposition of the Units contrary to the provisions of this Agreement, and any levy of any attachment or similar process upon the Units, shall be null and void and without effect.

9. Entire Agreement . This Agreement and the Employment Agreement contain all the understandings between the parties hereto pertaining to the matters referred to herein, and supersede all undertakings and agreements, whether oral or in writing, previously entered into by them with respect thereto. The Executive represents that, in executing this Agreement, he does not rely and has not relied upon any representation or statement not set forth herein made by the Company with regard to the subject matter, basis or effect of this Agreement or otherwise.

10. Amendment or Modification; Waiver . No provision of this Agreement may be amended, modified or waived unless such amendment or modification is agreed to in writing, signed by the Executive and by a duly authorized officer of the Company, and such waiver is set forth in writing and signed by the party to be charged. No waiver by any party hereto of any breach by another party hereto of any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of a similar or dissimilar condition or provision at the same time, any prior time or any subsequent time.

The Company hereby grants to the Employee a non-qualified stock option (the “Option”) to purchase all or any part of an aggregate of the number of shares of Common Stock as set forth in the attached Notice of Grant, subject to adjustment in accordance with Section 8 of the Plan.

2. Purchase Price . The purchase price per share of the shares of Common Stock covered by the Option shall be that set forth in the attached Notice of Grant, subject to adjustment in accordance with Section 8 of the Plan. It is the determination of the Company’s Compensation Committee (the “Committee”) that on the Grant Date the per share Option exercise price was not less than the greater of one hundred percent (100%) of the fair market value of the Common Stock, or the par value thereof.

3. Term . Unless earlier terminated pursuant to any provision of this Option Agreement, this Option shall expire on the date set forth in the attached Notice of Grant (the “Expiration Date”). Notwithstanding anything herein to the contrary, this Option shall not be exercisable after the Expiration Date.

4. Exercise of Option . This Option shall vest and become exercisable with respect to 1/3 ^rd of the shares subject hereto on the first anniversary of the [Grant Date]. Thereafter, this Option shall vest and become exercisable with respect to 1/24 ^th of the remaining shares on the first business day of each following month.

Any portion of the Option that becomes exercisable in accordance with the foregoing shall remain exercisable, subject to the provisions contained in this Option Agreement,

until the expiration of the term of this Option as set forth in Paragraph 3 or until other termination of the Option as set forth in this Option Agreement.

Notwithstanding anything contained herein, no portion of the Option which has not become vested and exercisable as of the Employee’s termination of employment or in connection with Employee’s termination of employment shall thereafter become vested or exercisable.

5. Method of Exercising Option . Subject to the terms and conditions of this Option Agreement, the Option may be exercised in whole or in part by written notice to the Company, at its principal office, which currently is located at 311 Enterprise Drive, Plainsboro, New Jersey 08536. Such notice shall state the election to exercise the Option, and the number of shares with respect to which it is being exercised; shall be signed by the person or persons so exercising the Option; shall, unless the Company otherwise notifies the Employee, be accompanied by the investment certificate referred to in Paragraph 6; and shall be accompanied by payment of the full Option price of such shares.

The Option price shall be paid to the Company: (i) in cash; (ii) in cash equivalent; (iii) in Common Stock of the Company, in accordance with Section 7.1(f)(ii) of the Plan (as in effect on the date of this Option Agreement); (iv) by delivering a properly executed notice of exercise of the Option, in accordance with Section 7.1(f)(iii) of the Plan (as in effect on the date of this Option Agreement); (v) in Common Stock of the Company issuable pursuant to the exercise of the Option or otherwise withheld in net settlement of the Option, in accordance with Section 7.1(f)(iv) of the Plan (as in effect on the date of this Option Agreement); or (vi) by any combination of (i)-(v).

Upon receipt of such notice and payment, the Company, as promptly as practicable, shall deliver or cause to be delivered a certificate or certificates representing the shares with respect to which the Option is so exercised. Such certificate(s) shall be registered in the name of the person or persons so exercising the Option (or, if the Option is exercised by the Employee and if the Employee so requests in the notice exercising the Option, shall be registered in the name of the Employee and the Employee’s spouse, jointly, with right of survivorship) and shall be delivered as provided above to or upon the written order of the person or persons exercising the Option. In the event the Option is exercised by any person or persons after the legal disability or death of the Employee, such notice shall be accompanied by appropriate proof of the right of such person or persons to exercise the Option. All shares that are purchased upon the exercise of the Option as provided herein shall be fully paid and not assessable by the Company.

6. Shares to be Purchased for Investment . Unless the Company has theretofore notified the Employee that a registration statement covering the shares to be acquired upon the exercise of the Option has become effective under the Securities Act of 1933 and the Company has not thereafter notified the Employee that such registration statement is no longer effective, it shall be a condition to any exercise of this Option that the shares acquired upon such exercise be acquired for investment and not with a view to distribution, and the person effecting such

2

exercise shall submit to the Company a certificate of such investment intent, together with such other evidence supporting the same as the Company may request. The Company shall be entitled to delay the transferability of the shares issued upon any such exercise to the extent necessary to avoid a risk of violation of the Securities Act of 1933 (or of any rules or regulations promulgated thereunder) or of any state laws or regulations. Such restrictions may, at the option of the Company, be noted or set forth in full on the share certificates.

7. Non-Transferability of Option . This Option is not assignable or transferable, in whole or in part, by the Employee other than by will or by the laws of descent and distribution, and during the lifetime of the Employee the Option shall be exercisable only by the Employee or by his or her guardian or legal representative.

8. Termination of Employment . If the Employee’s employment with the Company and all Related Corporations is terminated for any reason other than death or disability prior to the Expiration Date, this Option may be exercised, to the extent of the number of shares with respect to which the Employee could have exercised it on the date of such termination of employment, or to any greater extent permitted by the Committee, by the Employee at any time prior to the earlier of:

9. Disability . If the Employee incurs a disability, as defined in the Plan, during his or her employment with the Company and Related Corporations and, prior to the Expiration Date, the Employee’s employment is terminated as a consequence of such disability, this Option may be exercised, to the extent of the number of shares with respect to which the Employee could have exercised it on the date of such termination of employment, or to any greater extent permitted by the Committee in its discretion, by the Employee, or in the event of the Employee’s legal disability, by the Employee’s legal representative, at any time prior to the earlier of:

10. Death . If the Employee dies during his or her employment with the Company and Related Corporations and prior to the Expiration Date, or if the Employee’s employment is terminated for any reason (as described in Paragraphs 8 or 9 above) and the Employee dies following his or her termination of employment but prior to the earliest of the Expiration Date or the expiration of the period determined under Paragraph 8 or 9 above, this Option may be exercised, to the extent of the number of shares with respect to which the Employee could have exercised it on the date of his or her death, or to any greater extent permitted by the Committee, by the Employee’s estate, personal representative or beneficiary who acquired the right to exercise this Option by bequest or inheritance or by reason of the Employee’s death, at any time prior to the earlier of:

3

11. Withholding of Taxes . The obligation of the Company to deliver shares of Common Stock upon the exercise of the Option shall be subject to applicable federal, state and local tax withholding requirements. If the exercise of any Option is subject to the withholding requirements of applicable federal, state or local tax laws, the Committee, in its discretion, may permit the Employee, subject to the provisions of the Plan and such additional withholding rules (the “Withholding Rules”) as shall be adopted by the Committee, to satisfy the withholding tax, in whole or in part, by electing to have the Company withhold (or by returning to the Company) shares of Common Stock, which shares shall be valued, for this purpose, at their fair market value on the date of exercise of the Option (or, if later, the date on which the Employee recognizes ordinary income with respect to such exercise). An election to use shares of Common Stock to satisfy tax withholding requirements must be made in compliance with and subject to the Withholding Rules. The Committee may not withhold shares in excess of the number necessary to satisfy the minimum tax withholding requirements.

12. Construction . Except as would be in conflict with any specific provision herein, this Option Agreement is made under and subject to the provisions of the Plan as in effect on the Grant Date and, except as would conflict with the provisions of this Option Agreement, all of the provisions of the Plan as in effect on the Grant Date are hereby incorporated herein as provisions of this Option Agreement. Notwithstanding the foregoing, provisions of this Option Agreement that conflict with the Plan will be given effect only to the extent they do not exceed the Committee’s discretion under the Plan.

13. Governing Law . This Non-Qualified Stock Option Agreement shall be governed by applicable federal law and otherwise by the laws of the State of Delaware.

Exhibit 10.3

December 20, 2011

Dr. Richard E. Caruso

Chairman of the Board of Directors

Integra LifeSciences Holdings Corporation

311 Enterprise Drive

Plainsboro, NJ 08536

Dear Rich:

As we have discussed, I hereby consent and agree as follows with respect to my employment relationship with Integra LifeSciences Holdings Corporation (the “ Company ”), effective as of January 3, 2012:

1. Position: I agree that my new position and title will be Executive Chairman of the Company’s Board of Directors (the “ Board ”).

2. Base Salary: I agree that, notwithstanding Section 3.1 of the Second Amended and Restated Employment Agreement, dated as of July 27, 2004, as amended from time to time, between me and the Company (the “ Employment Agreement ”), my annual base salary rate for 2012 will not be increased from my 2011 annual base salary and will remain at $750,000 per year. However, any other amounts under the Employment Agreement that are determined based on my base salary will be calculated using the annual base salary to which I would have otherwise been entitled under Section 3.1 of my Employment Agreement had my base salary been increased in accordance with such provisions.

3. Annual Performance Bonus. I agree that, unless otherwise determined by the Compensation Committee of the Board in its sole discretion, I will not be eligible or entitled to receive an annual performance bonus described in Section 3.3 of the Employment Agreement or to participate in the Company’s annual incentive bonus plan for the Company’s 2012 fiscal year or thereafter.

4. Annual Equity Award. I acknowledge that the Annual Award (as defined in the Employment Agreement) that the Company determines to grant me for the Company’s 2011 fiscal year may be granted in the first quarter of 2012 (rather than December 2011 pursuant to Section 3.2(c)(i)(C) of the Employment Agreement). I further acknowledge that, unless otherwise determined by the Compensation Committee of the Board in its sole discretion, I will not be eligible or entitled to receive an Annual Award for the Company’s 2012 fiscal year or thereafter.

I agree that neither the foregoing nor any action taken by the Company in connection therewith (including the appointment of a new Chief Executive Officer of the Company or any related action) will constitute a breach of, or Good Reason for purposes of, the Employment Agreement or any other agreement between me and the Company. Otherwise, I retain my rights under such agreements.
