3.Administration of the Plan.

(a)Administration by the Committee. The Committee shall be responsible for the management and control of the operation and the administration of the Plan, including interpretation of the Plan, decisions pertaining to eligibility to participate in the Plan, computation of severance benefits, granting or denial of severance benefit claims and review of claims denials. The Board may, in its discretion, exercise any or all of such powers granted to the Committee under the Plan, in which case, all references in the Plan to the Committee shall be deemed to refer to the Board. The Committee has absolute discretion in the exercise of its powers and responsibilities. For this purpose, the Committee’s powers shall include the following authority, in addition to all other powers provided by the Plan:

(i)to make and enforce such rules and regulations as it deems necessary or proper for the efficient administration of the Plan;

(ii)to interpret the Plan, the Committee’s interpretation thereof to be final and conclusive on all persons claiming benefits under the Plan;

(iii)to decide all questions concerning the Plan and the eligibility of any person to participate in the Plan;

(iv)to appoint such agents, counsel, accountants, consultants, claims administrator and other persons as may be required to assist in administering the Plan;

(v)to allocate and delegate its responsibilities under the Plan and to designate other persons to carry out any of its responsibilities under the Plan, any such allocation, delegation or designation to be in writing;

(vi)to sue or cause suit to be brought in the name of the Plan; and

(vii)to obtain from the Company, its Affiliates and from Eligible Executives such information as is necessary for the proper administration of the Plan.

(b)Indemnification of the Committee. The Company shall, without limiting any rights that the Committee may have under the Company’s charter or bylaws, applicable law or otherwise, indemnify and hold harmless the Committee and each member thereof (and any other individual acting on behalf of the Committee or any member thereof) against any and all expenses and liabilities arising out of such person’s administrative functions or fiduciary responsibilities, excepting only expenses and liabilities arising out of the person’s own gross negligence or willful misconduct. Expenses against which such person shall be indemnified hereunder include the amounts of any settlement, judgment, attorneys’ fees, costs of court, and any other related charges reasonably incurred in connection with a claim, proceeding, settlement, or other action under the Plan.

(c)Compensation and Expenses. The Committee shall not receive additional compensation with respect to services for the Plan. To the extent required by applicable law, but not otherwise, the Committee shall furnish bond or security for the performance of their duties hereunder. Any expenses properly incurred by the Committee incident to the administration, termination or protection of the Plan, including the cost of furnishing bond, shall be paid by the Company.

4.Eligibility. Only individuals who are Eligible Executives may participate in the Plan. The Committee has full and absolute discretion to determine and select which employees of the Company Group are Eligible Executives. Once an employee has been designated as an Eligible Executive, such individual shall automatically continue to be an Eligible Executive until the Eligible Executive ceases to be an employee of the Company and its Affiliates. The Plan shall supersede all prior agreements, practices, policies, procedures and plans, including any Executive Employment Agreement, relating to severance payments or benefits from all members of the Company Group with respect to the Eligible Executives relating to a Qualifying Termination during a Change in Control Protection Period.

5.Plan Benefits.

(a)Qualifying Termination During a Change in Control Protection Period. In the event an Eligible Executive’s employment with any member of the Company Group ends due to a Qualifying Termination that occurs during a Change in Control Protection Period, such Eligible Executive shall be entitled to receive the Accrued Amounts, and so long as such Eligible Executive satisfies the Release Requirement, then:

(i)The Company shall make a severance payment to such Eligible Executive in a total amount equal to (x) in the case of Eligible Executives other than the CEO, two times the sum of (I) twelve (12) months’ worth of such Eligible Executive’s Base Salary plus (II) such Eligible Executive’s Target Annual Bonus, and (y) in the case of the CEO, two-and-a-half times the sum of (I) twelve (12) months’ worth of the CEO’s Base Salary plus (II) the CEO’s Target Annual Bonus (the “CiC Severance Payment”); and

(ii)The Company will pay such Eligible Executive a single lump sum payment in a total amount equal to (x) in the case of Eligible Executives other than the CEO, two times the total of twelve (12) months’ worth of an amount equal to the difference between the “applicable premium” under COBRA for such coverage elected by the Eligible Executive and the employee contribution amount that such Eligible Executive pays per month for coverage under a group health plan of the Company and its Affiliates as of the relevant Date of Termination, and (y) in the case of the CEO, two-and-a-half times the total of twelve (12) months’ worth of an amount equal to the difference between the “applicable premium” under COBRA for such coverage elected by the Eligible Executive and the employee contribution amount that such Eligible Executive pays per month for coverage under a group health plan of the Company and its Affiliates as of the relevant Date of Termination (the “COBRA Subsidy Payment”); provided, however, that the election of COBRA continuation coverage and the payment of any premiums due with respect to such COBRA continuation coverage shall remain such Eligible Executive’s sole responsibility, and the Company shall not assume any obligation for payment of any such premiums relating to such COBRA continuation coverage.

The CiC Severance Payment plus the COBRA Subsidy Payment will be paid to the Eligible Executive in one lump sum payment on the Company’s first regularly scheduled pay date that is on or after the date that the Release Requirement is satisfied, provided that in no event shall the CiC Severance Payment or the COBRA Subsidy Payment be paid to the Eligible Executive after March 15 of the calendar year following the calendar year in which the Eligible Executive receives the Release after the Date of Termination occurs.

(b)Equity Incentive Awards. For clarity, in the event that an Eligible Executive’s employment with any member of the Company Group terminates (pursuant to a Qualifying Termination or otherwise), all outstanding equity incentive awards then held by such Eligible Executive, pursuant to the Equity Incentive Plan or otherwise, will be treated in accordance with the award agreement applicable to such award or Equity Incentive Plan, as applicable. Notwithstanding the foregoing, all equity incentive awards granted by a successor of the Company or by the Eligible Executive’s new employer following a Change in Control, shall fully vest upon a Qualifying Termination during the Change in Control Protection Period.

(c)Non-Qualifying Terminations of Employment. In the event that an Eligible Executive’s employment with any member of the Company Group terminates other than pursuant to a Qualifying Termination, including as a result of death or Disability, then all compensation and benefits to such Eligible Executive shall terminate contemporaneously with such termination of employment, except that such Eligible Executive shall be entitled to the Accrued Amounts and all outstanding equity incentive awards and any deferred compensation awards or amounts then held by such Eligible Executive will be treated in accordance with the applicable award or grant agreement (if any) and the terms of the applicable plan.

(d)No Duplication. Except as otherwise expressly provided pursuant to this Plan, this Plan shall be construed and administered in a manner which avoids duplication of compensation and benefits which may be provided under any other plan, program, policy or other arrangement or individual contract or under any statute, rule or regulation.

6.Certain Excise Taxes. Notwithstanding anything to the contrary in the Plan, if an Eligible Executive is a “disqualified individual” (as defined in Section 280G(c) of the Code), and the payments and benefits provided for in the Plan, together with any other payments and benefits which such Eligible Executive has the right to receive from the Company or any of its Affiliates, and taking into account reductions in respect of reasonable compensation for personal services to be rendered by the Eligible Executive on or following the date of the relevant “change in ownership or control” (within the meaning of Section 280G of the Code), including pursuant to applicable non-competition and other restrictive covenant obligations, would constitute a

“parachute payment” (as defined in Section 280G(b)(2) of the Code), then the payments and benefits provided for in the Plan shall be either (a) reduced (but not below zero) so that the present value of such total amounts and benefits received by such Eligible Executive from the Company and its Affiliates will be one dollar less than three times such Eligible Executive’s “base amount” (as defined in Section 280G(b)(3) of the Code) and so that no portion of such amounts and benefits received by such Eligible Executive shall be subject to the excise tax imposed by Section 4999 of the Code or (b) paid in full, whichever produces the better net after-tax position to such Eligible Executive (taking into account any applicable excise tax under Section 4999 of the Code and any other applicable taxes). The reduction of payments and benefits hereunder, if applicable, shall be made by reducing, first, payments or benefits to be paid in cash hereunder in the order in which such payment or benefit would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time) and, then, reducing any benefit to be provided in-kind hereunder in a similar order. The determination as to whether any such reduction in the amount of the payments and benefits provided hereunder is necessary shall be made by the Company in good faith. If a reduced payment or benefit is made or provided and through error or otherwise that payment or benefit, when aggregated with other payments and benefits from the Company (or its Affiliates) used in determining if a “parachute payment” exists, exceeds one dollar less than three times such Eligible Executive’s base amount, then such Eligible Executive shall immediately repay such excess to the Company upon notification that an overpayment has been made. Nothing in this Section 6 shall require the Company to be responsible for, or have any liability or obligation with respect to, such Eligible Executives’ excise tax liabilities under Section 4999 of the Code.

7.Claims Procedure and Review.

(a)Filing a Claim. Any Eligible Executive that the Committee determines is entitled to severance benefits under the Plan is not required to file a claim for benefits. Any Eligible Executive (i) who is not paid severance benefits hereunder and who believes that such Eligible Executive is entitled to severance benefits hereunder or (ii) who has been paid severance benefits hereunder and believes that such Eligible Executive is entitled to greater benefits hereunder may file a claim for severance benefits under the Plan in writing with the Committee.

(b)Initial Determination of a Claim. If a claim for severance benefits hereunder is wholly or partially denied, the Committee shall, within a reasonable period of time but no later than ninety (90) days after receipt of the claim (or one-hundred and eighty (180) days after receipt of the claim if special circumstances require an extension of time for processing the claim), notify the claimant of the denial. Such notice shall (i) be in writing, (ii) be written in a manner calculated to be understood by the claimant, (iii) contain the specific reason or reasons for denial of the claim, (iv) refer specifically to the pertinent Plan provisions upon which the denial is based, (v) describe any additional material or information necessary for the claimant to perfect the claim (and explain why such material or information is necessary), and (vi) describe the Plan’s claim review procedures and time limits applicable to such procedures, including a statement of the claimant’s right to bring a civil action under Section 502(a) of ERISA following an adverse benefit determination on review.

(c)Appeal of a Denied Claim. Within sixty (60) days of the receipt by the claimant of this notice, the claimant may file a written appeal with the Committee. In connection with the appeal, the claimant may upon reasonable request, review Plan documents free of charge and may submit written issues and comments. In reviewing the appeal, the Committee will take into account all comments, documents, records, and other information submitted by the claimant related to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. The Committee shall deliver to the claimant a written decision on the appeal promptly, but not later than sixty (60) days after the receipt of the

claimant’s appeal (or one-hundred and twenty (120) days after receipt of the claimant’s appeal if there are special circumstances which require an extension of time for processing). Such decision shall (i) be in writing, (ii) be written in a manner calculated to be understood by the claimant, (iii) include specific reasons for the decision, (iv) refer specifically to the Plan provisions upon which the decision is based, (v) state that the claimant is entitled to receive, on request and free of charge, reasonable access to and copies of all documents, records, and other information relevant to the claimant’s claim for benefits, and (vi) a statement of the claimant’s right to bring an action under Section 502(a) of ERISA. If special circumstances require an extension of up to one-hundred and eighty (180) days for an initial claim or one-hundred and twenty (120) days for an appeal, whichever applies, the Committee shall send written notice of the extension. This notice shall indicate the special circumstances requiring the extension and state when the Committee expects to render the decision.

(d)Exhaustion of Remedies.No legal action for benefits under the Plan may be brought until the claimant (i) has submitted a written application for benefits in accordance with the procedures described by Section 7(a), (ii) has been notified by the Plan Administrator that the application is denied, (iii) has filed a written request for a review of the application in accordance with the appeal procedure described in Section 7(c), and (iv) has been notified that the Plan Administrator has denied the appeal. After exhaustion of the Plan’s claims procedures, any further legal action taken against the Plan or its fiduciaries by the claimant for benefits under the Plan shall be filed in a court of law no later than one (1) year after the final adverse determination on appeal. Notwithstanding the foregoing, if the Plan Administrator does not respond to an applicant’s claim or appeal within the relevant time limits specified in this Section 7, the applicant may bring legal action for benefits under the Plan pursuant to Section 502(a) of ERISA.

(e)Compliance with ERISA. The benefits claim procedure provided in this Section 7 is intended to comply with the provisions of 29 C.F.R. §2560.503-1. All provisions of this Section 7 shall be interpreted, construed, and limited in accordance with such intent.

8.General Provisions.

(a)Taxes. The Company is authorized to withhold from all payments made hereunder amounts of withholding and other taxes due or potentially payable in connection therewith, and to take such other action as the Company may deem advisable to enable the Company and the Eligible Executive to satisfy obligations for the payment of withholding taxes and other tax obligations relating to any payments made under the Plan.

(b)Offset. The Company may set off against, and each Eligible Executive authorizes the Company to deduct from, any payments due to the Eligible Executive, or to his or her estate, heirs, legal representatives, or successors, any amounts which may be due and owing to the Company or an Affiliate of the Company by the Eligible Executive, whether arising under the Plan or otherwise; provided, however, that no such offset may be made with respect to amounts payable that are subject to the requirements of Section 409A unless the offset would not result in a violation of the requirements of Section 409A.

(c)Amendment and Termination. Prior to a Change in Control, the Board and the Committee shall have the power to amend or terminate the Plan from time to time in its discretion and for any reason (or no reason) (including the removal of an individual as an Eligible Executive); provided that no such amendment or termination shall be effective with respect to a termination of employment that occurred prior to the amendment or termination of the Plan; and provided, further, that, to the extent any such amendment has a detrimental impact to any Eligible Executive, such amendment will become effective with respect to such Eligible Executive six months following approval by the Board or Committee. Notwithstanding the

foregoing, upon a Change in Control and during a Change in Control Protection Period, no amendment or termination of the Plan shall impair any rights or obligations to any Eligible Executive under the Plan (including the removal of an individual as an Eligible Executive) unless such Eligible Executive expressly consents to such amendment or termination.

(d)Successors. The Plan will be binding upon any successor to the Company, its assets, its businesses or its interest (whether as a result of the occurrence of a Change in Control or otherwise), in the same manner and to the same extent that the Company would be obligated under the Plan if no succession had taken place. All payments and benefits that become due to an Eligible Executive under the Plan will inure to the benefit of his or her heirs, assigns, designees or legal representatives.

(e)Transfer and Assignment. Neither an Eligible Executive nor any other person shall have any right to sell, assign, transfer, pledge, anticipate or otherwise encumber, transfer, hypothecate or convey any amounts payable under the Plan prior to the date that such amounts are paid.

(f)Unfunded Obligation. All benefits due an Eligible Executive under the Plan are unfunded and unsecured and are payable out of the general assets of the Company. The Company is not required to segregate any monies or other assets from its general funds with respect to these obligations. Eligible Executives shall not have any preference or security interest in any assets of the Company other than as a general unsecured creditor.

(g)Severability. If any provision of the Plan (or portion thereof) is held to be illegal or invalid for any reason, the illegality or invalidity of such provision (or portion thereof) will not affect the remaining provisions (or portions thereof) of the Plan, but such provision (or portion thereof) will be fully severable and the Plan will be construed and enforced as if the illegal or invalid provision (or portion thereof) had never been included herein.

(h)Section 409A. The Plan is intended to comply with Section 409A or an exemption thereunder and shall be construed and administered in accordance with Section 409A. Notwithstanding any other provision of the Plan, payments provided under the Plan may only be made upon an event and in a manner that complies with Section 409A or an applicable exemption. Any payments under the Plan that may be excluded from Section 409A either as separation pay due to an involuntary separation from service or as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. Any payments to be made under the Plan upon the termination of an Eligible Executive’s employment shall only be made if such termination of employment constitutes a “separation from service” under Section 409A. In no event may an Eligible Executive, directly or indirectly, designate the calendar year of any payment under this Plan. Each installment payment under the Plan is intended to be a separate payment for purposes of Section 409A. Notwithstanding any provision in the Plan to the contrary, if any payment or benefit provided for herein would be subject to additional taxes and interest under Section 409A if an Eligible Executive’s receipt of such payment or benefit is not delayed until the earlier of (i) the date of such Eligible Executive’s death or (ii) the date that is six months after such Eligible Executive’s Date of Termination (such date, the “Section 409A Payment Date”), then such payment or benefit shall not be provided to such Eligible Executive (or such Eligible Executive’s estate, if applicable) until the Section 409A Payment Date. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided under the Plan are exempt from, or compliant with, Section 409A and in no event shall the Company or any of its Affiliates be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by any Eligible Executive on account of non-compliance with Section 409A. For purposes of Section 409A, the Eligible Executive’s right to receive any installment payments pursuant to this Plan is treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Plan specifies a

payment period with reference to a number of days, the actual date of payment within the specified period is within the sole discretion of the Company.

(i)Governing Law. All questions arising with respect to the provisions of the Plan and payments due hereunder will be determined by application of the laws of the State of Delaware, without giving effect to any conflict of law provisions thereof, except to the extent preempted by federal law (including ERISA, which is the federal law that governs the Plan, the administration of the Plan and any claims made under the Plan).

(j)Status under ERISA. The Plan is intended to qualify for the exemptions under Title I of ERISA provided for plans that are unfunded and maintained primarily for the purpose of providing benefits for a select group of management or highly compensated employees.

(k)No Right to Continued Employment. The adoption and maintenance of the Plan shall not be deemed to be a contract of employment between the Company or any of its Affiliates and any person, or to have any impact whatsoever on the at-will employment relationship between the Company or any of its Affiliates and the Eligible Executives. Nothing in the Plan shall be deemed to give any person the right to be retained in the employ of the Company or any of its Affiliates for any period of time or to restrict the right of the Company or any of its Affiliates to terminate the employment of any person at any time.

(l)Title and Headings; Construction. Titles and headings to Sections hereof are for the purpose of reference only and shall in no way limit, define or otherwise affect the provisions hereof. Unless the context requires otherwise, all references herein to laws, regulations, contracts, documents, agreements and instruments refer to such laws, regulations, contracts, documents, agreements and instruments as they may be amended from time to time, and references to particular provisions of laws or regulations include a reference to the corresponding provisions of any succeeding law or regulation. The word “or” as used herein is not exclusive and is deemed to have the meaning “and/or.” The words “herein”, “hereof”, “hereunder” and other compounds of the word “here” shall refer to the entire Plan, and not to any particular provision hereof. Wherever the context so requires, the masculine gender includes the feminine or neuter, and the singular number includes the plural and conversely. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to similar items or matters, whether or not non-limiting language (such as “without limitation”, “but not limited to”, or words of similar import) is used with reference thereto, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter. Neither the Plan nor any uncertainty or ambiguity herein shall be construed or resolved against any party hereto, whether under any rule of construction or otherwise. On the contrary, the Plan has been reviewed by each of the parties hereto and shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of the parties hereto.

(m)Overpayment. If, due to mistake or any other reason, a person receives severance payments or benefits under the Plan in excess of what the Plan provides, such person shall repay the overpayment to the Company in a lump sum within thirty (30) days of notice of the amount of overpayment. If such person fails to so repay the overpayment, then without limiting any other remedies available to the Company, the Company may deduct the amount of the overpayment from any other amounts which become payable to such person under the Plan or otherwise.

(n)Clawback.Notwithstanding anything in this Plan or any other agreement between the Company and/or its related entities and an Eligible Executive to the contrary, such Eligible Executive acknowledges and agrees that any amounts payable under the Plan to such Eligible Executive are subject to (i) any right that the Company may have under any policy or other agreement or arrangement with such Eligible Executive (whether in existence as of the Effective Date or later adopted) established by the Company providing for clawback or recovery of amounts that were paid to such Eligible Executive, and (ii) any right or obligation that the Company may have regarding the clawback of “incentive-based compensation” under Section 10D of the Securities Exchange Act of 1934, as amended, and any applicable rules and regulations promulgated thereunder from time to time by the U.S. Securities and Exchange Commission, the listing standards of any national securities exchange or association on which the Company’s securities are listed, or any other applicable law. The Company will make any determination for clawback or recovery in its sole discretion and in accordance with applicable laws, regulations, and securities exchange listing standards.

(o)Agent for Service of Legal Process. Legal process may be served on the Committee, which is the plan administrator, at the following address: 3556 Lake Shore Road, Buffalo, New York.
