                              EMPLOYMENT AGREEMENT

      AGREEMENT dated March 7, 1997, between BRUCE J. HABER (the "Executive")
and HENRY SCHEIN, INC., a Delaware corporation (the "Company").

      The Executive is presently the President and Chief Executive Officer of
Micro Bio-Medics, Inc. ("MBM").

      The Company and MBM are parties to an Agreement and Plan of Merger dated
the date hereof (the "Merger Agreement"), pursuant to which it is contemplated
that HSI Acquisition Corp., a wholly-owned subsidiary of the Company, will be
merged with and into MBM.

      The Company desires to employ the Executive, and the Executive desires to
be employed by the Company, at the Effective Time, as that term is defined in
the Merger Agreement. Accordingly, the parties hereto are entering into this
Agreement to set forth and confirm their respective rights and obligations with
respect to the Executive's employment by the Company commencing as of the
Effective Time.

      The parties agree as follows:

      i.    Employment. The Company shall employ the Executive, as of the
            Effective Time, as Executive Vice President of the Company and
            President of the Company's medical products group and the Executive
            shall accept such employment and serve as such, subject to and upon
            the terms and conditions set forth in this Agreement; provided,
            however, that this Agreement shall terminate and be of no further
            force or effect if the Executive shall have died or, in the
            reasonable judgment of the Company, become disabled (as that term is
            used in Section 7(a)(i)(A) hereof), or his employment by MBM shall
            have been terminated for cause (as that term is defined in Section
            7(a)(i)(B) hereof), in any such case, prior to the Effective Time.
            At the Effective Time, the Executive's Employment Agreement with MBM
            dated February 11, 1992 (the "MBM Agreement"), as amended, shall
            terminate and be of no further force or effect.

                        Vice President of the Company and President of the
                        Company's medical products group. As President of the
                        Company's medical products group, the Executive shall
                        have the authority customarily vested in the chief

                        Employee's performance of his duties hereunder.

                        such family members shall first endeavor to obtain
                        reimbursement with respect to health and medical costs
                        from other insurance the Executive and such family
                        members may own, if any, provided that such
                        reimbursement can be obtained without unreasonable
                        effort or expense on the part of the Executive and such
                        family members. The Executive is hereby expressly not
                        required to mitigate damages or seek any other
                        employment;
<PAGE>

                        provided, however, that any amounts that the Executive
                        may receive from any other employment or consulting
                        engagement during the one-year period following such
                        termination shall reduce in equal amounts the amounts
                        that the Company otherwise is obligated to pay to the
                        Executive pursuant to clause (ii) of this Section 7(c).

                  (iv)  Upon termination of the Executive's employment hereunder
                        pursuant to Section 7(a)(i)(B) hereof or by the
                        Executive other than pursuant to Section 7(a)(ii)
                        hereof, the Executive shall be entitled to receive only
                        (i) his salary at the rate provided in Section 3(a) to
                        the date of such termination, and (ii) any unpaid bonus
                        pursuant to Section 3(b) in respect of the fiscal year
                        of the Company ended prior to the year in which such
                        termination occurs.

                  (v)   If the Company does not offer to extend the term of this
                        Agreement from and after the fifth anniversary of the
                        Effective Time, and the Executive is employed by the
                        Company at such date, the Executive shall be entitled to
                        receive continuation of the Executive's base salary for
                        a period of one year after such fifth anniversary at the
                        rate in effect at such anniversary.

      viii. Confidentiality and Non-Competition. In view of the unique and
            valuable services it is expected the Executive will render to the
            Company, the Executive's knowledge of the customers, trade secrets,
            and other proprietary information relating to the business of the
            Company and its customers and suppliers, and in consideration of the
            compensation to be received hereunder, the Executive agrees that he
            will not, during his employment with the Company and (x) for three
            years thereafter in the case of a termination pursuant to Section
            7(a)(i) of this Agreement, (y) for one-half of the unexpired term of
            this Agreement but not less than one year in case of a termination
            pursuant to Section 7(a)(ii) of this Agreement or a termination by
            the Company other than pursuant to Section 7(a)(i) of this
            Agreement, and (z) for two years in case of a non-renewal pursuant
            to Section 7(e) of this Agreement: (a) directly or indirectly engage
            or be interested (whether as owner, partner, lender, consultant,
            employee, agent, supplier, distributor or otherwise) in any
            business, activity or enterprise which competes with any aspect of
            the business conducted by the Company or any of the Company's
            affiliates (including MBM) at any time
<PAGE>

            prior to termination of his employment with the Company; (b) except
            on behalf of the Company, directly or indirectly employ or otherwise
            engage, or offer to employ or otherwise engage, any person who is
            then (or was at any time within one year prior to the time of such
            employment, en gagement or offer thereof) an employee or sales
            representative of the Company or any of the Company's affiliates
            (including MBM); or (c) except on behalf of the Company, solicit any
            business from any person or entity that has been a customer of the
            Company or any of the Company's affiliates (including MBM) or
            directly or indirectly induce or influence any customer, supplier or
            other person that has a business relationship with the Company or
            any of the Company's affiliates (including MBM) to discontinue or
            reduce the extent of such relationship with the Company or any of
            the Company's affiliates (including MBM); and provided further, that
            nothing herein contained shall preclude the Executive (i) from
            holding not more than two (2%) percent of the total outstanding
            stock of a publicly held company, and (ii) at any time after
            termination of his employment hereunder, soliciting any business
            from any person or entity that has been a customer of the Company or
            any of the Company's affiliates (including MBM), provided such
            solicitation does not involve the offer of products or services
            comparable to, or that could be reasonably deemed in substitution
            for, products or services theretofore offered by the Company or any
            of the Company's affiliates (including MBM) and (iii) investing in
            (provided he owns no more than 5% of the outstanding equity) and
            serving on the board of directors of an entity currently developing
            software to enable manufacturers of medical products to track
            rebates. In addition, the Executive shall never use or divulge any
            trade secrets, customer or supplier lists, pricing information,
            marketing arrangements or strategies, business plans, internal
            performance statistics, training manuals or other information
            concerning the Company or its affiliates that is competitively
            sensitive or confidential, except on behalf of the Company, and
            shall not conduct himself in a manner that would reasonably be
            expected to adversely affect the Company in any material respect,
            including but not limited to making knowingly false, misleading or
            negative statements, either orally or in writing, about the Company
            or its affiliates, or their respective directors, officers or
            employees; provided, however, that this sentence shall not apply to
            the following: (i) information which is already in the public domain
            at the time of its disclosure to the Executive; (ii) information
            which, after its disclosure to the Executive, becomes part of the
            public domain by publication or otherwise other than through the
            Executive's act; (iii) information which was in the Executive's
            possession before it was disclosed to him by the Company as shall be
            evidenced by written documents dated prior to the time of
            disclosure; (iv) information which the Executive received from a
            third party having the right to make such disclosure without
            restriction on disclosure or use thereof; or (v) information which
            the Executive is legally compelled to disclose. Because 
<PAGE>

            the breach or attempted or threatened breach of this restrictive
            covenant will result in immediate and irreparable injury to the
            Company for which the Company will not have an adequate remedy at
            law, the Company shall be entitled, in addition to all other
            remedies, to a decree of specific performance of this covenant and
            to a temporary and permanent injunction enjoining such breach,
            without posting bond or furnishing similar security. The provisions
            of this Section 8 are in addition to and independent of any
            agreements or covenants contained in any consulting or other
            agreement between the Company and the Executive. If any restriction
            contained in this Section 8 shall be deemed to be invalid, illegal,
            or unenforceable by reason of the extent, duration, or geographical
            scope thereof, or otherwise, then the court making such
            determination shall have the right to reduce such extent, duration,
            geographical scope, or other provisions hereof, and in its reduced
            form such restriction shall then be enforceable in the manner
            contemplated hereby.

                                    EXHIBIT A

Fiscal 1997

If Adjusted Pre-Tax Earnings (as defined below) is greater than $6 million an
amount equal to $65,000, plus, if Adjusted Pre-Tax Earnings is $7,000,000 or
more an additional amount equal to $135,000 multiplied by a fraction, the
numerator of which is the excess of such Adjusted Pre-Tax Earnings over $7
million (such excess not to exceed $1 million) and the denominator of which is
1,000,000. In determining whether any adjustment with respect to the foregoing
is necessary or desirable, the Compensation Committee of the Board of Directors
shall take into account synergies achieved with, and contribution to, the
Company's medical products division.

      For purposes of the preceding paragraph, "Adjusted Pre-Tax Earnings" shall
mean, net income of MBM for the twelve-month period ending in December, 1997,
less the base salary and cost of benefits payable or provided pursuant to this
agreement with respect to such period, before income taxes, as determined in
accordance with generally accepted accounting principles consistently applied
(but with charges for corporate overhead and for inter-corporate borrowing costs
in a manner consistent with charges to other divisions of the Company and in no
event in a proportion greater than the percentage which the division sales bear
to total Company sales) adjusted as follows: pre-tax earnings will be after all
bonuses paid to MBM employees, will include financing costs for all payments and
expenses related to the Merger and associated transactions.

Fiscal 1998-2001

An amount, not less than $200,000, determined by the Compensation Committee of
the Company's Board of Directors upon achievement by the executive of
performance targets to be set by such Committee in consultation with the
Executive. Among the matters to be taken into account by the Compensation
Committee in connection with its determination shall be synergies achieved with,
and contribution to, the Company's medical products division.

                            CLASS B OPTION AGREEMENT
                                 PURSUANT TO THE
                             1994 STOCK OPTION PLAN

      AGREEMENT dated _____________, 1997, between Henry Schein, Inc. (the
"Corporation") and Bruce J. Haber (the "Participant").

                              Preliminary Statement

      The Stock Option Committee of the Board of Directors of the Corporation
(the "Committee"), pursuant to the Corporation's 1994 Stock Option Plan, as
amended (the "Plan"), has authorized the granting to the Participant, as a Key
Employee, of a nonqualified stock option (the "Option") to purchase the number
of shares of the Corporation's Common Stock, par value $.01 per share, set forth
below. The parties hereto desire to enter into this Agreement in order to set
forth the terms of the Option. Capitalized terms used but not defined herein
shall have the same meanings as set forth in the Plan.

      Accordingly, the parties hereto agree as follows:

      A. Tax Matters. No part of the Option granted hereby is intended to
qualify as an "incentive stock option" under Section 422 of the Internal Revenue
Code of 1986, as amended.

      B. Grant of Option. Subject in all respects to the Plan and the terms and
conditions set forth herein, the Participant is hereby granted the Option to
purchase from the
<PAGE>

Corporation up to (a) shares (the "Shares"), at a price per Share of $ (b) (the
"Option Price"). Subject to Sections D and E hereof, the Option may be exercised
by the Participant, in whole or in part, at any time or from time to time prior
to the expiration of the Option as provided herein.

      C. Restriction on Transfer. The Option granted hereby is not transferable
otherwise than by will or under the applicable laws of descent and distribution
and during the lifetime of the Participant may be exercised only by the
Participant or his guardian or legal representative, provided, however, that,
from and after the date that the Plan is amended to provide for such transfers,
the Options may be transferred by the Participant to his wife or daughter or to
trusts the sole beneficiaries of which are the Participant's wife or daughter.
Except as provided in the preceding sentence, the Option shall not be assigned,
negotiated, pledged or hypothecated in any

----------
(a)   At the Effective Time, pursuant to Section 3(c) of the Participant's
      employment agreement with the Corporation, the Participant will be issued
      options ("Closing Options") to purchase shares of the Corporation's Common
      Stock having a value of $1,000,000 determined by application of the
      Block-Shares formula in the same manner in which it is applied in granting
      options to the Corporation's other most senior executives. In addition,
      and subject to the satisfaction of the performance targets set forth in
      Exhibit A thereto, pursuant to Section 3(d) of the Participant's
      employment agreement with the Corporation, the Participant will be issued
      options ("Annual Option") to purchase shares of the Corporation's Common
      Stock in respect of each fiscal year of the Corporation during which he is
      employed under the employment agreement, issuable no later than 90 days
      after the end of each year for which such options are issuable, such
      number of Annual Options to have a value of $170,000 determined by
      application of the Block- Shares formula in the same manner in which it is
      applied in granting options to the Corporation's other most senior
      executives:

      The value of options to be granted after the Effective Time shall be
      increased or decreased, as the case may be, to reflect the cumulative
      change in the [CPI] between the date of the Effective Time and the date of
      grant.

(b)   In all cases, the fair market value on the date of grant.


                                       15

way (whether by operation of law or otherwise), and the Option shall not be
subject to execution, attachment or similar process. Upon any attempt to
transfer, assign, negotiate, pledge or hypothecate the Option not expressly
permitted hereby, or in the event of any levy upon the Option by reason of any
execution, attachment or similar process contrary to the provisions hereof, the
Option shall immediately become null and void.

      D. Term of Option. Unless terminated as provided below or otherwise
pursuant to the Plan, the Option shall expire on the tenth anniversary of the
date of grant.

      E. Exercise of Option.

            1. No Options may be exercised unless and until such Options shall
have become vested. (c) of the Options granted hereunder shall automatically and
immediately vest on each of the (d) anniversaries of the date hereof, provided
that the Participant is employed by the Corporation on such anniversary dates.
The Chief Executive Officer of the Corporation shall have the right to
accelerate the vesting of any such Options in his sole discretion.

            2. The Option may be exercised by the Participant by delivering
notice to the Committee of the election to exercise the Option and of the number
of Shares with respect to which the Option is being exercised, which notice
shall be accompanied by payment in full for the Shares. Payment for such Shares
may be made as follows:

----------
(c)   "One-fifth (1/5)" in the case of Closing Options; and "One-third (1/3)" in
      the case of Annual Options.

(d)   "first, second, third, fourth and fifth" in the case of Closing Options;
      and "first, second and third" in the case of Annual Options.

<PAGE>

                  (a) In cash or by certified check, bank draft or money order
payable to the order of the Corporation;

                  (b) Through the delivery of unencumbered Shares (including
Shares to be acquired under the Options then being exercised) provided such
Shares (or such Option) have been owned by the Participant for at least six
months, or such longer period as required by applicable accounting standards to
avoid a charge to earnings;

                  (c) If so permitted by the Committee (i) through a combination
of Shares and cash as provided above, (ii) by delivery of a promissory note of
the Participant to the Corporation, or (iii) by a combination of cash (or cash
and Shares) and the Participant's promissory note; provided, that, if the Shares
delivered upon exercise of the Option is an original issue of authorized Shares,
at least so much of the exercise price as represents the par value of such
Shares shall be paid in cash or by a combination of cash and Shares; or

                  (d) On such terms and conditions as may be acceptable to the
Committee and in accordance with applicable law.

            3. Upon receipt of payment and satisfaction of the requirements, if
any, as to withholding of taxes set forth in the Plan, the Corporation shall
deliver to the Participant as soon as practicable a certificate or certificates
for the Shares then purchased.

            4. The exercise of any Option after termination of employment shall
be subject to satisfaction of the conditions precedent that the Participant be
in compliance with Section 8 of his employment agreement with the Corporation
(as amended, revised or replaced from time to time, the "Employment Agreement").
If the Participant exercises his Options and the Corporation


                                       17
<PAGE>

determines that the Participant subsequently (within a year following
termination of employment) engages in conduct which would have breached such
Section 8 had it taken place prior to exercise of the Options, then the
Participant hereby agrees to immediately return to the Corporation any financial
benefit he received from the Options upon request of the Corporation.

            5. Upon a change in control (as defined in the Plan), the Options
shall immediately become vested, unless two-thirds of members of the Board of
Directors have approved the change of control, in which event, there shall be no
