Section 3.01 Termination of Employment. During the Term, the Executive’s employment hereunder may be terminated without any breach of this Agreement under the following circumstances:

(a) Death. The Executive’s employment hereunder shall terminate upon Executive’s death.

-3-

(b) Disability. The Company may terminate the Executive’s employment if Executive is disabled and unable to perform the essential functions of the Executive’s then existing position or positions under this Agreement with or without reasonable accommodation for a period of 180 days (which need not be consecutive) in any 12-month period (“Disability”). If any question shall arise as to whether during any period the Executive is disabled so as to be unable to perform the essential functions of the Executive’s then existing position or positions with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable detail by a physician selected by the Company to whom the Executive or the Executive’s guardian has no reasonable objection as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue. The Executive shall cooperate with any reasonable request of the physician in connection with such certification. If such question shall arise and the Executive shall fail to submit such certification, the Company’s determination of such issue shall be binding on the Executive. Nothing in this Section 3.01(b) shall be construed to waive the Executive’s rights, if any, under existing law including, without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. §2601 et seq. and the Americans with Disabilities Act, 42 U.S.C. § 12101 et seq.

(c) Termination by the Company for Cause. The Company may terminate the Executive’s employment hereunder at any time for Cause. “Cause” shall exist with respect to the Executive for purposes of this Agreement if the CEO in consultation with the Board has made a good-faith determination that Executive has:

(ii) willfully failed to comply with any valid and legal directive of the CEO;

(iii) engaged in dishonesty, illegal conduct or misconduct, which is, in each case, materially injurious to the Company or any of its affiliates or any member of the Company Group (as defined below);

(vi) willfully violated a material policy of the Company; and/or

(vii) materially breached any material obligation under this Agreement.

Notwithstanding anything to the contrary contained herein, if the Executive is terminated by the Company for Cause, but an arbitrator or court makes a determination, which determination is not subject to further appeal or after any right to appeal has expired, that Cause did not exist, then such termination shall be deemed a termination without Cause for all purposes hereunder.

-4-

(d) Termination Without Cause. The Company may terminate the Executive’s employment hereunder at any time without Cause. A termination without Cause is any termination that does not: (i) constitute a termination by the Company for Cause under Section 3.01(c); (ii) result from the death or Disability of the Executive under Sections 3.01(a) or (b); or (iii) result from the Executive’s resignation for any reason (including, without limitation, Executive’s resignation with or without Good Reason and any Accelerated Resignation (each, as defined below)).

(e) Termination by the Executive. The Executive may terminate the Executive’s employment hereunder at any time for any reason, including but not limited to with or without Good Reason, subject to applicable notice periods and requirements as set forth herein. “Good Reason” means, for purposes of this Agreement, the occurrence of any one or more of the following events without the Executive’s prior written consent: (a) the assignment to the Executive of any duties materially and adversely inconsistent with the Executive’s position, duties and responsibilities (including reporting relationships or status with the Company), or a material reduction in the scope of the Executive’s duties or responsibilities (including reporting relationships), or in Executive’s position or title; (b) a material reduction in the Executive’s Base Salary and/or Target Bonus, except for across-the-board annual base salary reductions or target bonus reductions for the Company’s senior executives; (c) the Company’s (i) relocation of its principal executive office in the Greater Philadelphia, PA area to a location more than fifty miles (or such longer distance that is the minimum permissible distance under the circumstances for purposes of the involuntary separation from service standards under the Treasury Regulations or other guidance under Section 409A) from such principal executive office and (ii) requiring the Executive to relocate Executive’s principal work location to such new principal executive office (except for required travel on business for the Company Group), but only if such relocation results in a material increase to Executive’s normal daily commute; (d) in the case of a Change in Control, the failure of the Company to cause a successor entity to assume and agree to perform this Agreement; or (e) any material breach by the Company of any material provision of this Agreement. Notwithstanding the foregoing, the Executive’s employment will not be deemed to have resigned for Good Reason unless (i) the Executive provides the Company with written notice setting forth in reasonable detail the facts and circumstances claimed by the Executive to constitute Good Reason within 30 days after the date of the occurrence of any event that the Executive knows or should reasonably have known to constitute Good Reason, (ii) the Company fails to cure such acts or omissions within 30 days following its receipt of such notice, and (iii) the effective date of the Executive’s resignation with Good Reason occurs no later than 30 days after the expiration of the Company’s cure period.

Notwithstanding the foregoing, in the event that the Executive resigns for any reason (other than a resignation with Good Reason) and gives a Notice of Termination to the Company, the Company may unilaterally accelerate the Termination Date to any earlier effective date (an “Accelerated Resignation”) and such Accelerated Resignation shall not result in or be treated as a termination by the Company as of such earlier effective date for purposes of this Agreement.

Section 3.02 Accrued Obligations. In the event of any termination of the Executive’s employment pursuant to Section 3.01 above, the Executive shall be entitled to receive Executive’s Accrued Obligations. As used in this Agreement, “Accrued Obligations” shall mean: (i) the Executive’s earned but unpaid Base Salary through the Termination Date and accrued vacation if consistent with company policy; (ii) any unpaid expense or other reimbursements due pursuant to Section 2.04 hereof; and (iii) vested employee benefits in accordance with the terms of the applicable employee benefit plans.

-9-

(d) Executive represents and warrants that Executive has (i) disclosed to the Company all agreements with current or former employers that restrict or purport to restrict Executive’s post-employment activities or impose post-employment obligations (e.g. confidentiality, noncompete, nonsolicitation agreements, etc.), and (ii) complied and will continue to comply with all of Executive’s continuing obligations to Executive’s current and former employers, including in particular any obligations not to retain, use, or disclose confidential information or solicit employees.

Section 4.03 Noncompetition and Nonsolicitation. The Executive acknowledges that in the course of Executive’s employment with the Company Executive will become familiar with trade secrets and other confidential information concerning the Company Group and that Executive’s services will be of special, unique and extraordinary value to the Company. Therefore, the Executive agrees that:

(a) Noncompetition. During the Term and for a period of one year thereafter, the Executive shall not, anywhere in the world, directly or indirectly, own, manage, control, participate in, consult with, render services that are similar to the services that Executive provided to the Company for, or in any manner engage in, any business that is a Competing Business as of the relevant date of determination. Nothing herein shall prohibit the Executive from (i) being a passive investor in mutual, hedge or private equity funds (or similar investment vehicles), or (ii) being a passive owner of not more than 5% of the outstanding stock of any class of any entity so long as the Executive has no active participation in the business of such entity. For purposes of this Agreement, the “relevant date of determination” shall mean (x) the date upon which the Executive commences to engage in such activity with respect to any activity commenced during the Term, or (y) the Termination Date with respect to any activity Executive commences to engage in after the Termination Date. Executive may provide services to a division, subsidiary or affiliate of an entity that has a separate division, subsidiary or affiliate that operates a Competing Business only if (i) neither Executive nor the division, subsidiary or affiliate to which Executive is providing service engages in activities of the Competing Business, (ii) Executive has no direct or indirect participation or involvement in the Competing Business and no substantive or business-related discussions with employees or officers of the Competing Business, (iii) the Competing Business is not based out of the same location where Executive is based, and (iv) Executive provides assurances upon request that Executive is completely “walled off” from the activity of the Competing Business.

(b) Nonsolicitation. During the Term and for a period of one year thereafter, the Executive shall not, other than in the good faith performance of Executive’s duties for the Company hereunder, directly or indirectly through another entity induce or attempt to induce any employee of the Company Group to leave the employ of any member of the Company Group. Notwithstanding the foregoing, this Section 4.03(b) shall not be violated by any general solicitation not targeted at Company employees or by Executive serving as a reference upon request.

Section 4.04 Enforcement. If, at the time of enforcement of Section 4.03, a court holds that the restrictions stated therein or herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum duration, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum duration, scope and area permitted by law. Because the Executive’s services are unique and because the Executive has

-10-

access to Confidential Information, the parties hereto agree that money damages would be an inadequate remedy for any breach of this Agreement. Therefore, in the event a breach or threatened breach of this Agreement, the Company and its successors or permitted assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security).

Section 4.05 Additional Acknowledgments. The Executive acknowledges that the provisions of this Article IV are in consideration of: (i) the Executive’s employment with the Company, (ii) the equity interests described in Section 2.03, above, (iii) the severance payments described in Article III, and (iv) additional good and valuable consideration as set forth in this Agreement. In addition, the Executive agrees and acknowledges that the restrictions contained in this Article IV do not preclude the Executive from earning a livelihood, nor do they unreasonably impose limitations on the Executive’s ability to earn a living. In addition, the Executive acknowledges (i) that the business of the Company Group is and will be international in scope and without geographical limitation, (ii) notwithstanding the state of incorporation/formation or principal office of the Company or any other member of the Company Group, it is expected that the Company Group has and will have business activities and valuable business relationships within its industry throughout the world, and (iii) as part of his responsibilities, the Executive will be traveling around the world in furtherance of the Company Group’s business and relationships. The Executive agrees and acknowledges that the potential harm to the Company Group of the non-enforcement of this Article IV outweighs any potential harm to the Executive of their enforcement by injunction or otherwise. The Executive acknowledges that Executive has carefully read this Agreement and has given careful consideration to the restraints imposed upon the Executive by this Agreement, and is in full accord as to their necessity for the reasonable and proper protection of Confidential Information. The Executive expressly acknowledges and agrees that each and every restraint imposed by this Agreement is reasonable with respect to subject matter, time period and geographical area.

Regs. Section 1.409A-1 (including without limitation, the short-term deferral exemption or the permitted payments under Treas. Regs. Section 1.409A-1(b)(9)(iii)(A)), shall be delayed and paid or provided, without interest, on the earlier of (i) the date which is six months after the Executive’s “separation from service” (as such term is defined in Section 409A and the regulations and other published guidance thereunder) for any reason other than death, and (ii) the date of the Executive’s death.

(c) “Termination of employment,” “resignation” or words of similar import, as used in this Agreement shall mean, with respect to any payments subject to Section 409A, the Executive’s “separation from service” as defined by Section 409A. After any Termination Date, the Executive shall have no duties or responsibilities that are inconsistent with having a “separation from service” within the meaning of Section 409A and, notwithstanding anything in the Agreement to the contrary, distributions upon termination of employment of nonqualified deferred compensation may only be made upon a “separation from service” as determined under Section 409A and such date shall be the Termination Date for purposes of this Agreement. Each payment under this Agreement or otherwise shall be treated as a separate payment for purposes of Section 409A. In no event may the Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement which constitutes a “nonqualified deferral of compensation” within the meaning of Section 409A and to the extent an amount is payable within a time period, the time during which such amount is paid shall be in the discretion of the Company. If any payment subject to Section 409A is contingent on the delivery of a release by Executive and could occur in either of two years, the payment will occur in the later year.

(d) All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A, including, where applicable, the requirement that (i) any reimbursement shall be for expenses incurred during the period of time specified in this Agreement, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other calendar year, (iii) 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 (iv) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.

Section 5.03 Merger Clause. As of the Commencement Date, this Agreement (together with exhibits attached hereto) contains the complete, full, final and exclusive understanding between the Executive and the Company as to its subject matter hereof and supersedes and replaces any prior term sheets, understandings or agreements between the Executive and the Company (and its affiliates).

Section 5.04 Assignment.

(a) This Agreement is personal to the Executive. Neither the Company nor the Executive may make any assignment of this Agreement or any interest herein, by operation of law or otherwise, without the prior written consent of the other party. For purposes of this Section, consent on the part of the Company means the written, signed consent of the Board. Notwithstanding the foregoing, the Company may assign its rights under this Agreement without any such further consent of the Executive to any successor in interest to the Company including in the event that the Company shall effect a reorganization, consolidate with or merge into any other corporation, limited liability company, partnership, organization or other entity, or transfer all or substantially all of its properties or assets to any other corporation, limited liability company, partnership, organization or other entity, in which event all references to the “Company” shall be deemed to mean the assignee or a designated affiliate of the assignee. The Executive hereby consents to such assignment as set forth in the immediately preceding sentence and further acknowledges and agrees that no further consent by the Executive is necessary to make such assignment. This Agreement shall inure to the benefit of and be binding upon the Company and the Executive, their respective successors, executors, administrators, heirs and permitted assigns.

(b) Notwithstanding the foregoing Section 5.04(a), this Agreement and all rights of the Executive hereunder shall inure to the benefit of, and be enforceable by, the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive should die while any earned and unpaid amounts would otherwise still be payable to Executive hereunder if Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the Executive’s devisee, legatee or other designee or, should there be no such designee, to the Executive’s estate.

Section 5.05 Dispute Resolution. Except as provided in the last sentence of this Section, to the fullest extent permitted by law, the Company and the Executive agree to waive their rights to seek remedies in court, including any right to a jury trial. The Company and the Executive agree that any dispute between or among them or their subsidiaries, affiliates or related entities arising out of, relating to or in connection with this Agreement or the Executive’s employment with the Company, will be resolved in accordance with a two-step dispute resolution procedure involving: (1) Step One: non-binding mediation, and (2) Step Two: binding arbitration under the Federal Arbitration Act, 9 U.S.C. section 1 et. seq., or state law, whichever is applicable. Any such mediation or arbitration hereunder shall be conducted in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices of the JAMS (f/k/a the Judicial Arbitration and Mediation Service) (“JAMS”) pursuant to its then current JAMS Employment Arbitration Rules & Procedures (a copy of which is available through JAM’s website, www.jamsadr.org) (the “JAMS Rules”). Notwithstanding anything to the contrary in the JAMS Rules, the mediation process (Step One) may be ended by either party to the dispute upon notice to the other party that it desires to terminate the mediation and proceed to the Step Two arbitration; provided, however, that neither party may so terminate the mediation process prior to the occurrence of at least one (1) mediation session with the mediator. No arbitration shall be initiated or take place with respect to a given dispute if the parties have successfully achieved a mutually agreed to resolution of the dispute as a result of the Step One mediation. The mediation session(s) and, if necessary, the arbitration hearing shall be held in Philadelphia, Pennsylvania or any other location mutually agreed to by the parties hereto. The arbitration (if the dispute is not resolved by mediation) will be conducted by a single JAMS arbitrator, mutually selected by the parties, as

-13-

provided for by the JAMS Rules. If required by law, the Company will be responsible for the JAMS charges, including the costs of the mediator and arbitrator, otherwise the parties will share such charges equally. The Company and the Executive agree that the arbitrator shall apply the substantive law of Delaware to all state law claims, federal law to any federal law claims, and the Federal Arbitration Act with respect to disputes concerning this Section, that discovery shall be conducted in accordance with the JAMS Rules or as otherwise permitted by law as determined by the arbitrator. The arbitrator’s award shall consist of a written statement as to the disposition of each claim and the relief, if any, awarded on each claim. The Company and the Executive understand that the right to appeal or to seek modification of any ruling or award by the arbitrator is limited under state and federal law. Any award rendered by the arbitrator will be final and binding, and judgment may be entered on it in any court of competent jurisdiction in Philadelphia, Pennsylvania at the time the award is rendered or as otherwise provided by law. Nothing contained herein shall restrict either party from seeking temporary injunctive relief in a court of law. Judgment upon any arbitration award may be entered into any court having jurisdiction thereof and the parties consent to the jurisdiction of any court of competent jurisdiction located in the Commonwealth of Pennsylvania. Each party shall pay its own legal fees in event of a dispute.

Section 5.06 GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN THE STATE OF DELAWARE, INTERPRETATION, CONSTRUCTION AND PERFORMANCE OF THIS AGREEMENT IN ALL RESPECT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAW.

Section 5.07 Amendment; No Waiver. No provision of this Agreement may be amended, modified, waived or discharged except by a written document signed by the Executive and duly authorized officer of the Company. The failure of a party to insist upon strict adherence to any term of this Agreement on any occasion shall not be considered as a waiver of such party’s rights or deprive such party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. No failure or delay by any party in exercising any right or power hereunder will operate as a waiver thereof, nor will any single or partial exercise of any other right or power. No agreement or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by any party, which are not set forth expressly in this Agreement.

Section 5.08 280G; Limitations on Payments.

(a) Notwithstanding any other provision of this Agreement, in the event that any payment or benefit received or to be received by the Executive (including any payment or benefit received in connection with a termination of the Executive’s employment, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement) (all such payments and benefits, including the payments and benefits under Section 3.03 hereof, being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan, arrangement or agreement, the cash severance payments under this Agreement shall first be reduced, and the noncash severance payments hereunder shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (i) the net amount of such

-14-

Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). In all cases, if there are any reductions to the Total Payments under this paragraph, the reduction shall be performed in a manner which results in the greatest after-tax amount being retained by the Executive and in manner which comports with Section 409A.

(b) For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments the receipt or enjoyment of which the Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account; (ii) no portion of the Total Payments shall be taken into account which, in the written opinion of an independent, nationally recognized accounting firm (the “Independent Advisors”) selected by the Company (provided however that Independent Advisors may not without the Executive’s written consent be the firm which serves as the auditor for the ultimate parent of the entity acquiring the Company) does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base amount” (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Independent Advisors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

Section 5.09 Severability. If any term or provision of this Agreement is invalid, illegal or incapable of being enforced by any applicable law or public policy, all other conditions and provisions of this Agreement shall nonetheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. Upon any such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 5.10 Survival. The rights and obligations of the parties under the provisions of this Agreement that relate to post-termination obligations shall survive and remain binding and enforceable, notwithstanding the expiration of the term of this Agreement, the termination of the Executive’s employment with the Company for any reason or any settlement of the financial rights and obligations arising from the Executive’s employment hereunder, to the extent necessary to preserve the intended benefits of such provisions.

-15-

Section 5.11 Notices. All notices and other communications required or permitted by this Agreement will be made in writing and all such notices and communications will be deemed to have been duly given when delivered or (unless otherwise specified) emailed, mailed by United States certified or registered mail, return receipt requested, postage prepaid, addressed, if to the Company, to its General Counsel at its principal office, and if to the Executive, at the Executive’s last address on file with the Company. Either party may change such address from time to time by notice to the other.

Section 5.12 Headings and References. The headings of this Agreement are inserted for convenience only and neither constitute a part of this Agreement nor affect in any way the meaning or interpretation of this Agreement. When a reference in this Agreement is made to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated.

Section 5.13 Counterparts. This Agreement may be executed in one or more counterparts (including via facsimile), each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument.

Section 5.14 Contingencies. This Agreement, and Executive’s employment and continued employed, is contingent upon the following: (a) the Company’s receipt of satisfactory results to a standard pre-employment drug screen; (b) the Company’s receipt of satisfactory results to a full pre-employment background check; (c) there being no obligations (disclosed or undisclosed) to any third party, including Executive’s current or prior employer, that would prohibit or purport to prohibit Executive from performing any of Executives’ duties for the Company, in each case as determined by the Company; and (d) the Company’s receipt of proper authorization for Executive to work in the U.S, and Executive’s successful completion and/or satisfaction in a timely manner of any registration, licensing, and/or certification requirements necessary for Executive’s role. If any of the foregoing contingencies is not satisfied, this Agreement shall be null and void, and the Company shall have no further obligations to Executive.
