Definitions

to provide the terms and conditions relating to a Participant’s eligibility for certain benefits upon a Termination in connection with a Change in Control;

to recruit and retain certain highly qualified individuals as Employees; and

to maintain the focus of Employees on the business of the Company or the Parent and to mitigate the distractions caused by the possibility that the Employee’s employment may be terminated or that the Company or the Parent may be the target of an acquisition.

Eligibility. All Employees are eligible to participate in the Plan.

Participation. Participants are those Employees designated by the Administrator in its sole discretion to participate in the Plan; provided, however, that the Administrator is not permitted to designate an Employee as a new Participant following a Change in Control Date. An Employee who becomes a Participant will remain a Participant until the earlier of the date the Plan is terminated or the date all obligations of the Company and the Participant under the Plan are fulfilled. Participation will be evidenced by the Employee’s acknowledgment of his or her designation as a Participant in the form specified by the Administrator.

Severance Benefits. If a (I) Termination occurs during the Change in Control Protection Period, (II) the Participant has not been offered a Comparable Position, and (III) the Participant complies with the requirements of Section 4 below, the Participant will be eligible to receive the benefits set forth in this Section 3. A Participant’s benefits under this Section 3 will be in lieu of any benefits under an employment agreement between the Participant and the Company or the Parent, as applicable, except where such payment of a lump sum hereunder would result in a violation of Section 409A of the Code, to the extent applicable, in which case benefits under this Section 3 will be offset on a dollar for dollar basis for any benefits paid under the employment agreement and any excess payable under this Plan will be paid in a lump sum as provided under this Section 3. Determinations with respect to Code Section 409A (and offset described) will be made by the Administrator in its sole discretion.

Severance Pay. A lump sum cash payment equal to the sum of the following:

an amount equal to a pro rata portion of the annual bonus which would have been paid for the year in which the Termination Date occurs, with the amount determined based on 100% of the Participant’s “target” bonus for the calendar year of the Termination Date, multiplied by a fraction, the numerator of which is the number of calendar days in the year of the Termination Date prior to the Termination Date and the denominator is 365; provided, however, if the Participant is on an active performance management plan or a performance improvement plan, the amount of the pro rata portion of the annual bonus may be reduced in the sole discretion of the Administrator; plus

an amount equal to six (6) months of the Terminated Participant’s Salary; plus

the Change in Control Health Benefit.

Outplacement Assistance. Outplacement assistance as determined in the discretion of the Administrator, to be provided by a vendor selected by the Company in accordance with the terms of the applicable program then being offered by the Company. Outplacement assistance must commence within forty-five (45) days of the expiration of the Revocation Period (as defined in Section 3.5 below), and must be completed before the end of the calendar year following the year in which the Termination Date occurred.

Payment of Severance Pay to Beneficiaries. If a Terminated Participant dies after his or her Termination during the Change in Control Protection Period, all Severance Pay that would have been paid to the Terminated Participant under this Section 3 but for his or her death, will be paid to the Terminated Participant’s Beneficiary in a single lump sum payment within sixty (60) days following the Participant’s death.

Equity Plans. The Severance Benefits are in addition to the benefits, if any, under any equity incentive plan, program, or arrangement, which benefits will be determined solely in accordance with any such equity incentive plan, program, or arrangement.

Payment of Severance Pay. Severance Pay under this Section 3 will be paid in the form determined in the sole discretion of the Administrator, which form may include (1) a single lump sum payment; or (2) in equal installments in accordance with the Company’s regular payroll practice. Severance Pay shall begin to be paid on the first payroll period following the expiration of the time period for the Participant to revoke his or her execution of the Release (as defined in Section 4.1 below) as specified in the Release (the “Revocation Period”); provided, however, that in no event will the Severance Pay begin to be paid later than the sixtieth (60^th) day following the Termination Date.

Waiver and Release. As a condition for receiving Severance Benefits under this Plan, a Terminated Participant must timely execute (and not revoke) and deliver to the Company a waiver and release substantially in the form attached to the Plan as Exhibit A (the “Release”) within the time period specified in the Release. The Release, in final executable form as determined by the Administrator, will be provided to the Terminated Participant by the Company no later than five (5) days after the Termination Date.

Noncompetition. At all times during a Participant’s service with the Company or the Parent and for twelve (12) months following the Participant’s Termination Date, the Participant shall not, directly or indirectly, engage in a Competitive Activity.

Nonsolicitation. At all times during a Participant’s service with the Company or the Parent and for twelve (12) months following the Participant’s Termination Date, the Participant shall not directly or indirectly through another entity (a) induce or attempt to induce any employee of the Parent or the Company to leave the employ or service of the Parent or the Company, (b) induce or attempt to induce any customer, supplier, licensee, or other business relation of the Parent or the Company to cease doing business with the Parent or the Company, or (c) usurp any business opportunity presented to the Parent or the Company or which the Parent or the Company was, in good faith, considering prior to the Termination Date.

Confidentiality. At all times prior to and following a Participant’s Termination Date, the Participant shall not disclose to anyone or make use of any trade secret or proprietary or confidential information of the Company or the Parent, including trade secret or proprietary or confidential information of any customer or client or other entity to which the Company or the Parent owes an obligation not to disclose such information, which he or she acquires during his or her service with the Company or the Parent, including, but not limited to, records kept in the ordinary course of business, except:

as may be required or appropriate in connection with his or her work as an employee of the Company or the Parent;

when required to do so by a court of law, by any governmental agency having supervisory authority over the business of the Company or the Parent or by any administrative or legislative body (including a committee thereof) with apparent jurisdiction to order him or her to divulge, disclose, or make accessible such information, or in connection with whistleblower protections afforded under applicable Federal or state statute; (which shall not require prior notice to the Company), provided that neither the Company nor the Parent waives any attorney-client privilege;

with respect to confidential information that becomes generally known to the public or trade without his or her violation of this Section 4.4; or

to the Participant’s spouse and/or his or her personal tax and financial advisors as reasonably necessary or appropriate to advance the Participant’s tax, financial, and other personal planning (each an “Exempt Person”), provided, however, that any disclosure or use of any trade secret or proprietary or confidential information of the Company or the Parent by an Exempt Person shall be deemed to be a breach of this Section 4.4 by the Participant.

Non-Disparagement. At all times prior to and following a Participant’s Termination Date, the Participant shall not make any statements or express any views that disparage the business reputation or goodwill of the Parent or the Company, any officers, directors or mangers thereof or any products, whether orally, in writing, or in any electronic medium (including, without limitation, on any social media or similar platform).

Resignation as Officer and Manager. The Participant shall be deemed to resign as (a) an officer of the Company or the Parent, (b) a member of the board and similar body of the Company or the Parent, and (c) any trustee (or similar position) of any Company or Parent benefit plan, program, or trust as of his or her Termination Date.

Return of Company Property. On, before, or immediately following a Participant’s Termination Date, a Participant shall return all property of the Company or the Parent in his or her possession, including, but not limited to, all computer equipment (hardware and software), telephones, facsimile machines, Blackberrys/smart phones/PDAs, and other communication devices, credit cards, office keys, security access cards, badges, identification cards, and all copies (including drafts) of any documentation or information (however stored) relating to the business of the Company or the Parent, its and their customers and clients, or its and their prospective customers and clients.

Cooperation. A Participant’s entitlement to benefits under this Plan is conditioned on the Participant cooperating to the extent reasonably requested, as determined by the Administrator, to effect the applicable Change in Control. Without limiting the foregoing, following a Participant’s Termination Date, the Participant shall give his or her assistance

Enforcement of Section 4. If a Terminated Participant materially violates any provision of this Section 4, he or she shall immediately forfeit any right, title and interest to any Severance Benefits that have not yet been paid or provided, and the Terminated Participant shall be required to immediately repay to the Company on demand a cash amount equal to the gross amount of the Severance Benefits that he or she has already received or that were provided.

Enforcement of Noncompetition, Nonsolicitation and Confidentiality Covenants. In addition to Section 4.9 above, if a Terminated Participant violates or threatens to violate any provision of this Section 4, the Company shall not have an adequate remedy at law. Accordingly, the Company shall not be required to pay or provide (and the Participant shall forfeit without consideration) any amounts or Severance Benefits under Section 3 above, and the Company shall be entitled to such equitable and injunctive relief as may be available to restrain the Terminated Participant and any business, firm, partnership, individual, corporation, or entity participating in the breach or threatened breach from the violation of the provisions of this Section 4 (without having to post a bond or other security or proving inadequacy of monetary damages). Nothing in the Plan shall be construed as prohibiting the Company from pursuing any other remedies available at law or in equity for breach or threatened breach of this Section 4, including the recovery of damages.

Protected Activity. Nothing in this Plan shall preclude a Participant from: (a) engaging in concerted, protected activity under the National Labor Relations Act (such as discussing wages and terms and conditions of employment with co-workers) to the extent that the Participant is a non-managerial, non-supervisory employee; (b) taking any lawful action or making any disclosure to the extent protected or required by applicable law; or (c) communicating with, providing information to, testifying before, or otherwise assisting any governmental agency, official, or body with respect to a possible violation of any law, rule, or regulation. Without prior authorization from the Company’s Legal Department, however, the Company does not authorize the Participant to disclose to anyone a communication that is covered by the Company’s attorney-client privilege.

Blue Pencil. If, at any time, the provisions of this Section 4 are determined to be invalid or unenforceable under any applicable law, by reason of being vague or unreasonable as to area, duration or scope of activity with respect to a Participant, this Plan will be considered divisible and may become and be immediately amended (or reformed) to only such area, duration and scope of activity as is determined to be reasonable and enforceable by the court or other body having jurisdiction over the matter, and the Participant and the Company agree that this Plan as so amended will be valid and binding as though any invalid or unenforceable provision had not been included herein.

Claims Procedure. If any Participant or Beneficiary, or his or her legal representative (the “Claimant”), has a claim for benefits under the Plan which is not being paid, the Claimant may file a written claim with the Administrator setting forth the amount and nature of the claim, supporting facts, and the Claimant’s address. Written notice of the disposition of a claim by the Administrator will be furnished to the Claimant within ninety (90) days after the claim is filed. If the Administrator determines that special circumstances require an extension of time for processing the claim, the Administrator may take up to an additional ninety (90) days to process the claim, provided that written notice of the extension is furnished to the Claimant prior to the expiration of the initial ninety (90) day period, which notice will indicate the special circumstances requiring the extension and the date by which the Plan expects to render a decision.

Claims Review Procedure. If a Claimant whose claim has been denied wishes further consideration of his or her claim, he or she may request the Administrator to review the claim in a written request for review, which must be filed with the Administrator no later than sixty (60) days after receipt of the written notification of disposition provided for in Section 5.1 above. As part of the review, the Claimant will have the opportunity to submit written comments, documents, records, and other information relating to the claim for benefits; will be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the claimant’s claim for benefit. The Administrator will fully and fairly review the matter and will take into account all comments, documents, records, and other information submitted by the Claimant relating to the claim, without regard to whether it was submitted or considered in the initial benefit determination. The Administrator will notify the Claimant of its determination on review within sixty (60) days after receipt of the Claimant’s request for review. If the Administrator determines that special circumstances require an extension of time for processing the claim, the Administrator may take up to an additional sixty (60) days to

Dispute Resolution. Any disputes arising under or in connection with the Plan (other than proceedings for injunctive relief with respect to or in connection with Section 4 above) shall be resolved by binding arbitration, to be held in the Greater Philadelphia, Pennsylvania area or in any other location mutually agreed to by the Company and the applicable Participant in accordance with the rules and procedures of the American Arbitration Association. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. A Participant must exhaust the claims and appeals procedures set forth in Sections 5.1 and 5.2 above before requesting binding arbitration. A request for binding arbitration to resolve a dispute must be made no later than ninety (90) days following the Administrator’s final determination on review pursuant to Section 5.2 hereof.

Reimbursement of Expenses. If there is any dispute between the Company and a Participant with respect to a claim under the Plan, the Company will reimburse the Participant for all reasonable fees, costs and expenses incurred by the Participant with respect to the disputed claim; provided, however, that (i) the Participant is the prevailing party with respect to the disputed claim or (ii) the disputed claim is settled in the Participant’s favor.

Responsibility. The Administrator shall have the responsibility, in its sole discretion, to control, operate, manage and administer the Plan in accordance with its terms.

Authority of the Administrator. The Administrator shall have the maximum discretionary authority permitted by law that may be necessary to enable it to discharge its responsibilities with respect to the Plan, including, but not limited to, the following:

to determine eligibility for participation in the Plan and designate Employees as Participants;

to determine the occurrence of a Change in Control, whether a Termination was for Cause or Good Reason or other determinations hereunder;

to determine or calculate a Participant’s Severance Benefits;

to correct any defect, supply any omission, or reconcile any inconsistency in the Plan in such manner and to such extent as it shall deem appropriate in its sole discretion to carry the same into effect;

to issue administrative guidelines as an aid to administer the Plan and make changes in the guidelines as it from time to time deems proper;

to make rules for carrying out and administering the Plan and make changes in the rules as it from time to time deems proper;

to the extent permitted under the Plan, grant waivers of Plan terms, conditions, restrictions, and limitations; and

to take any and all other actions it deems necessary or advisable for the proper operation or administration of the Plan.

Action by the Administrator. The Administrator may act at a meeting (whether in person or by telephone or video conference) only by a vote or determination of a majority of its members. In addition, any vote or determination of the Administrator may be made, without a meeting, by a writing or writings signed by all of the members of the Administrator. In addition, the Administrator may authorize any one or more of its members to execute and deliver documents on behalf of the Administrator.

Delegation of Authority. The Administrator may delegate to one or more of its members, or to one or more agents, such administrative duties as it may deem advisable; provided, however, that any delegation shall be in writing. In addition, the Administrator, or any person to whom it has delegated duties, may employ one or more persons to render advice with respect to any responsibility the Administrator or they may have under the Plan. The Administrator may employ legal or other counsel, consultants, and agents as it may deem desirable for the administration of the Plan and may rely upon any opinion or computation received from any counsel, consultant or agent so engaged. Expenses incurred by the Administrator in the engagement of any counsel, consultant, or agent will be paid by the Company or the Parent whose employees have benefited from the Plan, as determined by the Administrator.

Determinations and Interpretations by the Administrator. All determinations and interpretations made by the Administrator shall be in the sole discretion of the Administrator and shall be binding and conclusive to the maximum extent permitted by law on all Participants and their heirs, successors, and legal representatives.

Information. The Company shall furnish to the Administrator in writing all information the Administrator may deem necessary, desirable or appropriate for the exercise of its powers and duties in the administration of the Plan. Such information may include, but shall not be limited to, the full names of all Participants, their earnings, and their dates of birth, employment, retirement or death. Such information shall be conclusive for all purposes of the Plan, and the Administrator shall be entitled to rely thereon without any investigation thereof.

Liability. The Administrator (including, if applicable, the members of the Parent Board) shall not be liable, and no Employee providing services to the Company or the Parent shall be liable, for any act or failure to act hereunder, except in circumstances involving his or her bad faith, gross negligence, or willful misconduct, or liable for any act or failure to act hereunder by any other member or employee or by any agent to whom duties in connection with the administration of the Plan have been delegated.

Indemnification. The Company shall indemnify the Administrator (including, if applicable, the members of the Parent Board) and any agent of the Administrator who is an Employee providing services to the Company or the Parent, against any and all liabilities or expenses to which they may be subjected by reason of any act or failure to act with respect to their duties on behalf of the Plan to the extent provided in the Company’s governing documents and under applicable law, except in circumstances involving the person’s bad faith, gross negligence, or willful misconduct.

Withholding Taxes. The Company and the Parent shall be entitled to withhold from any and all payments made under the Plan all federal, state, local, and/or other taxes which the Company determines are required to be so withheld from such payments or by reason of any other payments made to or on behalf of the Participant or for his or her benefit hereunder.

Golden Parachute Excise Tax. In the event that a Participant becomes subject to the excise tax imposed by Code Section 4999 (the “Parachute Excise Tax”) and/or the Company or the Parent would lose a tax deduction due to the imposition of Code Section 280G, any payments or benefits under the Plan will be reduced to the extent necessary to avoid the Parachute Excise Tax and/or loss of deduction, provided, that the Company may seek exemption under Code Section 280G’s shareholder approval exception, subject to the cooperation of “disqualified individuals” affected under Code Section 4999.

Code Section 409A. All amounts payable under this Plan are intended to comply with the “short term deferral” exception from Code Section 409A (“Section 409A”) specified in Treas. Reg. §1.409A-1(b)(4) (or any successor provision) or the separation pay plan exception specified in Treas. Reg. §1.409A-1(b)(9) (or any successor provision), or both of them, and shall be interpreted in a manner consistent with those exceptions. Notwithstanding the foregoing, to the extent that any amounts payable in accordance with this Plan are subject to Section 409A, the Plan shall be interpreted and administered in such a way as to comply with the applicable provisions of Section 409A to the maximum extent possible. To the extent that the Plan is subject to Section 409A and fails to comply with the requirements of Section 409A, the Company reserves the right (without any obligation to do so) to amend, restructure, terminate, or replace the Plan in order to cause the Plan either to comply with the applicable provisions of Section 409A or not be subject to Section

No Guarantee of Tax Consequences. No person connected with the Plan in any capacity, including, but not limited to, the Parent or the Company and their respective managers, officers, agents, and employees makes any representation, commitment, or guarantee that any tax treatment, including, but not limited to, federal, state, and local income, estate, and gift tax treatment, will be applicable with respect to benefits or amounts payable or provided under the Plan, or paid to or for the benefit of a Participant under the Plan, or that such tax treatment will apply to or be available to a Participant on account of participation in the Plan.

Term of Plan. The Plan shall be effective as of the Effective Date and shall remain in effect until the Parent Board terminates or suspends the Plan in accordance with Section 8.3 below.

Amendment of Plan. The Plan may be amended by the Parent Board at any time with or without prior notice; provided, however, that if the Plan is amended during the Change in Control Protection Period such amendment may not be adverse to a Participant with respect to eligibility or amount of payments or benefits hereunder without the written consent of such Participant(s).

Termination of Plan. The Plan may be terminated or suspended by the Parent Board at any time with or without prior notice; provided, however, that the Plan shall not be terminated or suspended during the Change in Control Protection Period without the written consent of a majority of the Participants.

No Adverse Effect. If the Plan is amended, terminated, or suspended in accordance with Section 8.2 or 8.3 above, such action shall not adversely affect the Severance Benefits of any Terminated Participant who, at the date of such amendment, termination or suspension, is already receiving or entitled to receive Severance Benefits under the Plan.

No Mitigation. A Terminated Participant shall be under no obligation to seek other employment following the Termination Date and there shall be no offset against amounts due the Terminated Participant under the Plan on account of any compensation attributable to any subsequent employment.

Offset; No Duplication of Benefits. Without limiting Section 3 above, and to the extent permitted by Section 409A, Severance Benefits provided hereunder shall automatically be reduced by any payment or benefit made or provided or to be made or to be provided by the Company or the Parent to the Participant pursuant to (i) the termination of employment/service provisions of any employment agreement or services arrangement between the Company or the Parent and the Participant, and (ii) any federal, state or local statute, rule, regulation or ordinance.

No Right, Title, or Interest in Company or Parent Assets. Participants shall have no right, title, or interest whatsoever in or to any assets of the Company or the Parent or any investments which the Company or the Parent may make to aid it in meeting its obligations under the Plan. Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company or the Parent and any Participant, Beneficiary, legal representative or any other person. To the extent that any person acquires a right to receive payments from the Company or the Parent under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company or the Parent. Subject to this Section 9.3, all payments to be made hereunder shall be paid from the general funds of the Company or the Parent and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts.

No Right to Continued Employment. The Participant’s rights, if any, to continue to serve the Company or the Parent as an employee or service provider shall not be enlarged or otherwise affected by his or her designation as a Participant under the Plan, and the Company or the Parent reserves the right to terminate the employment or service of any Employee at any time. The adoption of the Plan shall not be deemed to give any Employee, or any other individual, any right to be selected as a Participant or to continued employment or service with the Company or the Parent.

Governing Law. The Plan shall be governed by and construed in accordance with the laws of Pennsylvania without reference to principles of conflict of laws, except as superseded by ERISA and other applicable federal law.

Severability. If any term or condition of the Plan shall be invalid or unenforceable to any extent or in any application, then the remainder of the Plan, with the exception of such invalid or unenforceable provision, shall not be affected thereby and shall continue in effect and application to its fullest extent.

Incapacity. If the Administrator determines that a Participant or a Beneficiary is unable to care for his or her affairs because of illness or accident or because he or she is a minor, any benefit due the Participant or Beneficiary may be paid to the Participant’s spouse or to any other person deemed by the Administrator to have incurred expense for the Participant (including a duly appointed guardian, Administrator or other legal representative), and any such payment shall be a complete discharge of the Company’s obligation hereunder.

Transferability of Rights. The Plan shall be binding on and inure to the benefit of the executors, heirs, administrators, successors and assigns of a Participant and the successors and assigns of Company. The Company shall have the unrestricted right to transfer its obligations under the Plan with respect to one or more Participants to any person, including, but not limited to, any purchaser of all or any part of the Company’s business. No Participant or Beneficiary shall have any right to commute, encumber, transfer or otherwise dispose of or alienate any present or future right or expectancy which the Participant or Beneficiary may have at any time to receive benefits hereunder, which benefits and the right thereto are expressly declared to be non-assignable and nontransferable, except to the extent required by law. Any attempt to transfer or assign a benefit, or any rights granted hereunder, by a Participant or the spouse of a Participant shall, in the sole discretion of the Administrator (after consideration of such facts as it deems pertinent), be grounds for terminating any rights of the Participant or Beneficiary to any portion of the Plan benefits not previously paid or provided.

Non-Exclusivity. This Plan shall not prevent or limit a Participant’s continuing future participation in any benefit, bonus, incentive, severance plan or arrangement provided by the Company and for which the Participant may qualify.

Headings. The headings of this Plan are for convenience and reference only and do not constitute a part hereof.

Summary Document. Any summary document or other Plan summary is a summary of terms only and is qualified in its entirety by the terms of this Plan and any inconsistency of such document or summary with this Plan will be interpreted in favor of the Plan.

Successors. The Company shall cause any successor (whether direct or indirect, by purchase, merger, consolidation, or otherwise) to all or substantially all of its business and/or assets to expressly assume and agree to perform all of the Company’s obligation hereunder in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place.

Examine, without charge, at the Plan Administrator’s office and at other specified locations, such as worksites, all documents governing the Plan and a copy of the latest annual report (Form 5500 series) filed by the Plan with the U.S. Department of Labor, and available at the Public Disclosure Room of the Employee Benefits Security Administration.

Obtain, upon written request to the Plan Administrator, copies of all documents governing the operation of the Plan, and copies of the latest annual report (Form 5500 series) and updated summary plan description. The Plan Administrator may make a reasonable charge for the copies.
