Dear                :

            In recognition of your contributions to Henry Schein, Inc. ("HSI" or
the "Company") and the Company's desire to assure your continued services in the
event of a pending or actual Change in Control (as hereinafter defined) of HSI,
the Company's Board of Directors is pleased to offer you the Change in Control
protection outlined in this letter agreement ("Agreement"). This Agreement
amends and restates in its entirety any and all prior agreements between you and
the Company relating to the subject matter hereof.

      1.    Term Of Agreement. The term of this Agreement shall commence on the
date of this letter (the "Effective Date") and end on June 30, 2001 (the
"Original Term"). The Original Term may be renewed from time to time for a term
or terms to be determined by the Company, in its sole discretion (the "Renewal
Terms"). "Term" shall mean the Original Term and all Renewal Terms.
Notwithstanding the foregoing, if a Change in Control occurs during the Term,
the Term shall not expire earlier than two years from the date the Change in
Control occurs.

      2.    Entitlement to Cash Bonus. Provided (a) you are then employed by the
Company or (b) you were employed by the Company until your employment was
terminated by the Company without Cause or by you for Good Reason, in either
case, (i) within ninety (90) days prior to the effective date of the Change in
Control, or (ii) after the first public announcement of the pendency of the
Change in Control, upon the effective date of the

<PAGE>

Change in Control you shall be entitled to a cash payment equal to the Change in
Control Price (as defined), as determined as of such payment date, times       ,
such payment to be paid to you no later than 10 days after the effective date of
the Change in Control ("Bonus Payment Date"). In the event that the Change in
Control Price increases in the 50-day period after the Bonus Payment Date
occurs, you shall be entitled to receive an additional payment equal to the
product of such increase in the Change in Control Price times             ,
such amount payable to you no later than 60 days from the Bonus Payment Date.

      3.    Entitlement to Severance Benefits.

            (a) Cash Severance Benefit. In the event your employment is
      terminated (a "Termination") by the Company without Cause or by you for
      Good Reason, in either case within two years following a Change in
      Control, you shall be entitled to receive the sum of the following,
      payable in a cash lump sum no later than 15 days after the Termination
      date: (i) Base Salary through the Termination date; (ii) a pro rata annual
      incentive award at target for the year in which the Termination occurs,
      and (iii) an amount equal to 300% of the sum of your Base Salary plus your
      target annual cash bonus. In addition, notwithstanding the foregoing, in
      the event your employment is terminated by the Company without Cause or by
      you for Good Reason, in either case (i) within ninety (90) days prior to
      the effective date of a Change in Control, or (ii) after the first public
      announcement of the pendency of the Change in Control, such termination
      shall, upon the effective date of a Change in Control, be deemed to be a
      "Termination" covered under the preceding sentence of this Section 3(a),
      and you shall be entitled to the amounts provided for under the preceding
      sentence.

            (b) Other Severance Benefits. In the event you are entitled to the
      amounts provided for in Section 3(a) hereof, and notwithstanding anything
      to the contrary contained in any stock option or restricted stock
      agreement, you shall also be entitled to the following: (i) immediate
      vesting of all outstanding stock options to the fullest extent permitted
      under the applicable stock option plan; (ii) elimination of all
      restrictions on any restricted or deferred stock awards outstanding at the
      time of Termination, (iii) immediate vesting of all restricted or deferred
      stock awards and non-qualified retirement benefits, (iv) settlement of all
      deferred compensation arrangements in accordance with any then applicable
      deferred compensation plan or election form (iv) continued participation
      in all HSI's welfare benefit plans at the same benefit level at which you
      were participating on the Termination date for a

                                       2
<PAGE>

      period of 36 months unless and until the date or dates you receive
      substantially equivalent coverage from a subsequent employer.

            (c) Section 280(G) Gross-Up Protection. In the event you become
      entitled to payments, all or a portion of which become subject to tax
      imposed under Section 4999 of the Internal Revenue Code of 1986, as
      amended (the "Code") (or any other similar tax, but excluding any income
      tax of any nature)("Excise Tax"), HSI shall pay you an additional amount
      ("Gross-Up Payment") such that the amount retained by you after reduction
      for any Excise Tax (including penalties or interest thereon) equals the
      amount to be paid to you by HSI hereunder prior to the imposition of such
      Excise Tax. The amount of the Gross-Up Payment shall be calculated by
      HSI's independent auditors. In the event that such Gross-Up Payment is
      finally determined to be less than the amount necessary to provide that
      the amount to be retained by you after reduction for any Excise Tax
      (including penalties or interest thereon) equals the amount to be paid to
      you by HSI hereunder prior to the imposition of such Excise Tax, HSI shall
      pay an additional amount to you in respect of such deficiency (including
      any interest and penalties). In the event that such Gross-Up Payment is
      finally determined to exceed the amount necessary to provide that the
      amount to be retained by you after reduction for any Excise Tax (including
      penalties or interest thereon) equals the amount to be paid to you by HSI
      hereunder prior to the imposition of such Excise Tax, you must promptly
      repay the entire amount of such excess Gross- Up Payment to HSI.

            (d) No Mitigation; No Offset. In the event of any Termination, you
      shall be under no obligation to seek other employment and no amounts due
      to you under this Agreement shall be subject to offset due to any
      remuneration attributable to subsequent employment that you may obtain.

            (e) Exclusivity of Severance Payments; Release. In the event you are
      entitled to the amounts provided for in Section 3(a) hereof, you shall not
      be entitled to any other severance payments or severance benefits from HSI
      or any payments by HSI on account of any claim by you of wrongful
      termination, including claims under any federal, state or local human and
      civil rights or labor laws. Termination payments and benefits made to you
      are conditioned upon your execution of a release agreement, in a form
      reasonably satisfactory to HSI, releasing any and all claims arising out
      of your employment (other than enforcement of this Agreement), any rights
      under HSI's incentive compensation and employee benefit plans, and any
      claim for any non-employment related tort for personal injury.

            (a) During the Term and thereafter, you shall not, without HSI's

employees, advisors, businesses or reputations. Notwithstanding the foregoing,
nothing in this Agreement shall preclude you from making truthful statements or
disclosures that are required by applicable law, regulation or legal process.

      6.    Resolution of Disputes. Any controversy or claim arising out of or

any arbitration or court proceeding, HSI shall continue payment of all amounts
and benefits due you hereunder. All reasonable costs and expenses of any
arbitration or court proceeding (including fees and disbursements of counsel)
shall be promptly paid on your behalf by HSI; provided, however, that no such

determine(s) that any of your litigation assertions or defenses were in bad
faith or frivolous.

provided in this Agreement, the existence of this Agreement shall not be
interpreted to prohibit or restrict your participation in any other employee
benefit or other plans or programs in which you currently participate.

employment between you and HSI. HSI may terminate you at any time, subject to
the terms hereof or any other agreement that might exist between you and HSI.

      entitled to the amounts provided for in Section 3(a) hereof, you shall not
      be entitled to any other severance payments or severance benefits from HSI
      or any payments by HSI on account of any claim by you of wrongful
      termination, including claims under any federal, state or local human and

      reasonably satisfactory to HSI, releasing any and all claims arising out
      of your employment (other than enforcement of this Agreement), any rights
      under HSI's incentive compensation and employee benefit plans, and any

prior written consent disclose to anyone (except in good faith in the ordinary
course of business) or make use of any Confidential Information except in the
performance of your duties hereunder or when required to do so by law. In the
event that you are so required by law, you shall give prompt written notice to
HSI sufficient to allow HSI the opportunity to object to or otherwise resist
such order.

            (b) During the Term and for a period of 24 months thereafter, you
shall not, without HSI's prior written consent, solicit for employment, whether

following any Termination for any reason) you will not make statements or
representations, or otherwise communicate, directly or indirectly, in writing,
orally, or otherwise, or take any action which may, directly or indirectly,
disparage or be damaging to HSI or its respective officers, directors,
employees, advisors, businesses or reputations. Notwithstanding the foregoing,
nothing in this Agreement shall preclude you from making truthful statements or
disclosures that are required by applicable law, regulation or legal process.

      6.    Resolution of Disputes. Any controversy or claim arising out of or
relating to this Agreement or any breach or asserted breach hereof shall be
resolved by binding arbitration, to be held at an office closest to HSI's
principal offices in accordance with the rules and procedures of the American
Arbitration Association. Judgment upon the award rendered by the arbitrator(s)
may be entered in any court of competent jurisdiction. Pending the resolution of
any arbitration or court proceeding, HSI shall continue payment of all amounts
and benefits due you hereunder. All reasonable costs and expenses of any
arbitration or court proceeding (including fees and disbursements of counsel)
shall be promptly paid on your behalf by HSI; provided, however, that no such
expense reimbursement shall be made if and to the extent the arbitrator(s)
determine(s) that any of your litigation assertions or defenses were in bad
faith or frivolous.

      7.    Effect of Agreement on Other Benefits. Except as specifically
provided in this Agreement, the existence of this Agreement shall not be
interpreted to prohibit or restrict your participation in any other employee
benefit or other plans or programs in which you currently participate.

      8.    Not an Employment Agreement. This Agreement is not a contract of
employment between you and HSI. HSI may terminate you at any time, subject to
the terms hereof or any other agreement that might exist between you and HSI.

      9.    Assignability; Binding Nature. This Agreement shall be binding upon
and inure to the benefit of the parties and their respective successors, heirs
(as applies to you) and permitted assigns. HSI agrees that in the event of a
sale or transfer of assets, it shall, as a condition of such sale, require such
assignee or transferee to expressly assume HSI's liabilities, obligations and
duties hereunder.
