Exhibit 10.2

AMERISOURCEBERGEN DRUG CORPORATION

SUPPLEMENTAL RETIREMENT PLAN

(Amended and Restated November 24, 2008)

AMERISOURCEBERGEN DRUG CORPORATION

SUPPLEMENTAL RETIREMENT PLAN

In recognition of the services provided to AmerisourceBergen Drug Corporation (the “Sponsor”) and its Affiliates by certain management and highly compensated employees, the Sponsor and its Affiliates maintain the AmerisourceBergen Drug Corporation Supplemental Retirement Plan (the “Plan”) to provide such employees with retirement benefits that would otherwise be unavailable by reason of certain restrictive provisions of law applicable to the AmerisourceBergen Drug Corporation Participating Companies Pension Plan. The Plan was frozen effective as of June 30, 2007 and no further benefits accrued under the Plan after such date. This Amendment and Restatement of the Plan is made November 24, 2008, effective as of January 1, 2005, unless otherwise noted, and incorporates changes required to comply with Section 409A of the Internal Revenue Code.

Section 7.3. Claims Procedure.

(a) The Administrator will advise each Participant and Beneficiary of any benefits to which he is entitled under the Plan. If any person believes that the Administrator has failed to advise him of any benefit to which he is entitled, he may file a written claim with the Administrator. The claim shall be reviewed, and a response provided, within 90 days of the Administrator’s receipt of the claim; provided, however, that in special circumstances the Administrator may extend the response period for up to an additional 90 days provided the Administrator so notifies the claimant in writing and specifies the reason or reasons for such extension. Every claimant who is denied a claim for benefits shall be provided with written notice setting forth in a manner calculated to be understood by the claimant:

(1) the specific reasons or reasons for the denial;

(2) specific reference to pertinent Plan provisions on which denial is based;

(3) a description of any additional material or information necessary for the claimant to perfect the claim; and

(4) an explanation of the claim review procedure set forth in paragraph (b), below.

(b) Within 60 days of receipt by a claimant of a notice denying a claim under the Plan under paragraph (a), the claimant or his duly authorized representative may request in writing a full and fair review of the claim by the Benefits Committee. The Benefits Committee may extend the 60-day period where the nature of the benefit involved or other attendant circumstances make such extension appropriate. In connection with such review, the claimant or his duly authorized representative may review pertinent documents and may submit issues and comments in writing. The Benefits Committee shall make a decision promptly, and not later than 60 days after the Benefits Committee’s receipt of a request for review, unless special circumstances (such as the need to hold a hearing, if the Benefits Committee deems one necessary) require an extension of time for processing, in which case a decision shall be rendered as soon as possible, but not later than 120 days after receipt of a request for review. The decision on review shall be in writing and shall include specific reasons for the decision, written in a manner calculated to be understood by the claimant, and specific references to the pertinent Plan provisions on which the decision is based.

ARTICLE 8

AMENDMENT AND TERMINATION

Section 8.1. Authority to Amend. The Board may amend the Plan, by or pursuant to resolution, at any time in any manner whatsoever; provided however that the Benefits Committee may make all technical, administrative, regulatory, or compliance amendments to the Plan, and may make any other amendment which will not increase the cost of the Plan to the Participating Employers and the Sponsor by more than $100,000, or such greater

-5-

amount as determined by the Board, as the Benefits Committee shall deem necessary or appropriate without the approval of the Board or any Participating Employer. Amendments made by the Benefits Committee shall be in writing and signed by at least one Committee member.

Section 8.2. Right to Terminate. Continuance of the Plan is completely voluntary and is not assumed as a contractual obligation of the Participating Employers. The Sponsor shall have the right at any time for any reason to terminate the Plan, by resolution of the board. Furthermore, each Participating Employer may discontinue its participation in the Plan at any time by or pursuant to resolution of its board of directors or other governing body.

Section 8.3. Effect of Amendment or Termination. No amendment or termination of the Plan shall decrease or restrict any vested benefit which a Participant (or Beneficiary) has accrued under the Plan, as of the date of termination or amendment of the Plan based on the Participant’s accrued benefit under the Pension Plan on such date, unless the Participant (or Beneficiary) would have been entitled to a smaller benefit if the Plan had not been amended or terminated. For avoidance of doubt, however, the Sponsor may terminate the Plan and provide for immediate distributions of all benefits accrued hereunder (as though each Participant had experienced a Separation from Service as of the date of such termination), subject to the requirements of Treas. Reg. § 1.409A-3(j)(4)(ix) or any succeeding regulations.

ARTICLE 9

MISCELLANEOUS

Section 9.1. No Right to Employment. Nothing contained herein (a) shall be deemed to exclude a Participant from any compensation, bonus, pension, insurance, severance pay or other benefit to which he otherwise is or might become entitled to as an Employee or (b) shall be construed as conferring upon an Employee the right to continue in the employ of a Participating Employer.

Section 9.2. No Compensation for Other Benefits. Any amounts payable hereunder shall not be deemed salary or other compensation to a Participant for the purposes of computing benefits to which he may be entitled under any other arrangement established by a Participating Employer for the benefit of its employees.

Section 9.3. Rights and Obligations. The rights and obligations created hereunder shall be binding on a Participant’s heirs, executors and administrators and on the successors and assigns of the Participating Employers.

Section 9.4. Payments to Representatives. If any Participant or Beneficiary entitled to receive any benefits hereunder is determined by the Administrator, or is adjudged to be, legally incapable of giving valid receipt and discharge for such benefits, the benefits shall be paid to a duly appointed and acting conservator or guardian, or other legal representative of such Participant or Beneficiary, if any, and if no such legal representative is appointed and acting, to such person or persons as the Administrator may designated. Such payments shall, to the extent made, be deemed a complete discharge for such payments under this Plan.

-6-

Section 9.5. Governing Law. The Plan shall be construed in accordance with and governed by the laws of the Commonwealth of Pennsylvania.

Section 9.6. Nonalienation. Except as hereinafter provided with respect to family disputes, the rights of any Participant or Beneficiary under this Plan are personal and may not be assigned, transferred, pledge or encumbered, and any attempt to do so shall be void. In cases of family disputes, the Participating Employers will observe the terms of the Plan unless and until ordered to do otherwise by a state or federal court. As a condition of participation, a Participant agrees to hold the Participating Employers harmless from any claim that arises out of the Participating Employers’ obeying the final order of any state or Federal court, whether such order effects a judgment of such court or is issued to enforce a judgment or order of another court. For purposes of this Section 9.6, “family dispute” means a dispute relating to provision of child support, alimony payments, or marital property rights to a spouse, former spouse or other dependent of the Participant.

Section 9.7. Limitations on Obligations. Neither the Sponsor (nor any other Participating Employer) nor any member of the Board shall be responsible or liable in any manner to any Participant, Beneficiary or any person claiming through them for any benefit or action taken or omitted in connection with the granting of benefits, the continuation of benefits, or the interpretation and administration of this Plan.

Section 9.8. Withholding. If the Participating Employer is required to withhold amounts under applicable federal, state or local tax laws, rules or regulations, the Participating Employer shall be entitled to deduct and withhold such amounts from any cash payment made pursuant to this Plan.

Section 9.9. Lost Payees. Any benefit payable under the Plan shall be deemed forfeited if the Administrator is unable to locate the Participant or Beneficiary to whom payment is due; provided, however, that such benefit shall be reinstated if a claim is made by the Participant or Beneficiary for the forfeited benefit.
