          physical or mental incapacity, the Company shall continue to pay
          Executive his then current salary hereunder during the period of his
          disability; provided, however, that if Executive is disabled for a

6.   OBLIGATIONS OF EXECUTIVE DURING AND AFTER EMPLOYMENT.
     ---------------------------------------------------- 

     a.   No Competition. Executive acknowledges and agrees that he has and will
          ---------------                                                       
          have knowledge and access to Confidential Information (as defined in
          Paragraph 6b hereof) and responsibilities relating to all aspects of
          the business operations of the Company in all of the territories and
          geographical areas covered by the Company's business operations.
          Executive further acknowledges and agrees that this knowledge
          qualifies Executive as a potentially formidable competitor throughout
          the territories and geographical areas covered by the Company's
          business operations.

          Executive agrees that during the term of his employment under this
          Agreement, and for a period of one (1) year following Executive's
          Termination of Employment with the Company for any reason or for a
          period ending one (1) year after the date of entry by a court of
          competent jurisdiction of a final judgment enforcing the no
          competition provision of this Agreement, whichever is later, he will
          not, within the territories and the geographical areas covered by the
          Company's business operations, own, participate, engage or have any
          interest in, directly or indirectly, any person, firm, partnership,
          joint venture, corporation, or business (whether as an owner,
          employee, officer, director, agent, creditor, security holder or other
          investor, or consultant or in any other capacity which calls for the
          rendering of personal services, advice, acts of management, operation
          or control) which is competitive with the Company's or any affiliated
          company's medical and surgical supplies and wholesale pharmaceutical
          distribution businesses (including, without limitation, competitive
          with any products or services sold, investigated, developed or
          otherwise pursued by the Company or any affiliated company in such
          businesses at the time of Executive's Termination of Employment with
          the Company). For purposes of this Paragraph 6, "Executive's
          Termination of Employment with the Company" shall mean the latest of
          (i) the date on which the Company terminates Executive's employment
          for cause under Paragraph 7a hereof, (ii) the date on which Executive
          resigns or otherwise voluntarily leaves his employment with the
          Company, and (iii) the date on

 
          which any salary continuation payments to Executive under Paragraph 7c
          hereof cease.

     b.   UNAUTHORIZED USE OF CONFIDENTIAL INFORMATION. Executive acknowledges
          ---------------------------------------------                       
          and agrees that (i) during the course of his employment with the
          Company, Executive has or will have produced and/or has had or will
          have access to Confidential Information, as hereinafter defined, and
          (ii) the unauthorized use or disclosure of any such Confidential
          Information at any time would constitute unfair competition with the
          Company. Executive promises and agrees not to engage in any unfair
          competition with the Company either during or after the term of this
          Agreement. Therefore, during and subsequent to his employment with the
          Company, or by an affiliated company, Executive agrees to hold in
          confidence the Company's Confidential Information and not, directly or
          indirectly, disclose, publish, or otherwise make available to the
          public or to any individual, firm or corporation, or use, copy or make
          lists of any of the Company's Confidential Information, other than on
          behalf of the Company, except to the extent expressly authorized by
          the Company in writing. Executive further agrees that all Confidential
          Information, together with all records, files, drawings, document,
          equipment, and the like, or copies thereof, relating to the Company's
          business, or the business of an affiliated company, which Executive
          shall prepare, or use, or come into contact with, shall be and remain
          the sole property of the Company, or of an affiliated company, and
          shall not be removed (except to allow Executive to perform his
          responsibilities hereunder while traveling for business purposes or
          otherwise working away from his office) from the Company's or the
          affiliated company's premises without its prior written consent, and
          shall be promptly returned to the Company upon termination of
          employment with the Company and its affiliated companies. This
          Paragraph 6b shall survive the termination or expiration of this
          Agreement.

     c.   CONFIDENTIAL INFORMATION DEFINED. For purposes of this Agreement,
          ---------------------------------                                
          "Confidential Information" means all information (whether or not

          business or affairs of customers of the Company which was furnished to
          him by the Company or any of its agents or customers or otherwise
          discovered by him during his employment; provided, however, that
                                                   --------  -------      
          Confidential Information does not include information which (A)
          becomes available to the public other than as a result of disclosure

          duties at GMI have included and at the Company may continue to include
          the preparation of materials, including computer software and other
          written or graphic materials, and that any such materials conceived or
          written by him were done and shall continue to be done as "work made

          with such notice, the Company shall be released from any claim by
          Executive or by anyone in

 
          privity with him against the Company with respect to the use of any

          ---------                                                      
          Company may, without liability, terminate Executive's employment
          hereunder for cause at any time immediately upon written notice from
          the President of the Company or his designee specifying such cause. As

 
          used herein, the term "cause" shall mean (i) Executive's willful
          misconduct, dishonesty, or other knowing and material violation of the
          Company's policies and procedures in effect from time to time,
          following a written warning to cease or otherwise remedy such
          violation, (ii) actions (or failures to act) by Executive in bad faith
          and to the detriment of the Company, (iii) any breach or threatened
          breach of Paragraph 6 hereof, or (iv) a material breach by Executive
          of one or more terms of this Agreement, other than Paragraph 6 hereof,
          which breach Executive has not cured within thirty (30) days of his
          receipt of written notice from the Company of such breach; provided,
                                                                     -------- 
          however, that the term "cause" shall not mean Executive's refusal to
          --------                                                            
          relocate beyond a distance of thirty (30) miles at the request of the
          Company.

     b.   OTHER THAN FOR CAUSE; PERFORMANCE; REORGANIZATION. Notwithstanding
          --------------------------------------------------                
          anything herein to the contrary, the Company may also terminate
          Executive's employment (without regard to any general or specific
          policies of the Company relating to the employment or termination of
          its employees) should (i) Executive fail to perform his duties
          hereunder in a manner satisfactory to the President of the Company,
          provided that Executive shall first be given written notice of such
          unsatisfactory performance and a period of thirty (30) days to improve
          such performance to a level deemed acceptable to the President of the
          Company or, (ii) Executive's position be eliminated as a result of a
          reorganization or restructuring of the Company or its affiliated
          companies.

     c.   OBLIGATIONS OF COMPANY ON TERMINATION OF EMPLOYMENT. If the Company
          ---------------------------------------------------                
          terminates Executive's employment pursuant to Paragraph 7a hereof,
          then all of the Company's obligations hereunder shall immediately
          cease and terminate. Executive shall thereupon have no further right
          or entitlement to additional salary, incentive compensation payments
          or awards, or any perquisites from the Company whatsoever, and
          Executive's rights, if any, under the Company's employee and
          management benefit plans shall be determined solely in accordance with
          the express terms of the respective plans.

          If the Company terminates Executive's employment pursuant to Paragraph
          7b hereof, then, notwithstanding anything herein (or in any of the
          Company's benefit or incentive plans) to the contrary and in complete
          satisfaction and discharge of all of its obligations to Executive
          hereunder, the Company shall (i) continue Executive's then base
          salary, without increase, for the longest of (x) three (3) months, (y)
          such period set forth in Company policy and (z) the remainder of the

 
          term of this Agreement; provided, however, that the Company's
                                  --------  -------                    
          obligation to make such salary payments shall be reduced by any
          compensation received by Executive from a subsequent employer during
          such term, and (ii) consider Executive for a bonus under the terms of
          the MIP for the fiscal year in which termination occurs (but not for
          any subsequent year); provided, further, that any such bonus, if
                                --------  --------                        
          earned, shall be pro-rated to reflect the portion of the year for
          which Executive was actively employed.

          The Company and Executive agree that if Executive resigns or otherwise
          voluntarily leaves his employment with the Company prior to expiration
          of this Agreement, the Company shall be under no further obligation to
          make any additional payments or provide any benefits hereunder.

          Executive acknowledges and agrees that all of his obligations under
          Paragraph 6 hereof shall continue in full force and effect subsequent
          to any of the above-described terminations of his employment with the
          Company.

8.   GENERAL PROVISIONS.
     -------------------

     a.   Executive's rights and obligations under this Agreement shall not be
          transferable by him by assignment or otherwise, nor shall Executive's
          rights be subject to encumbrance or subject to the claims of the
          Company's creditors. Nothing in this Agreement shall prevent the
          consolidation of the Company with, or its merger into, any other
          corporation, or the sale by the Company of all or substantially all of
          its properties or assets; and this Agreement shall inure to the
          benefit of, be binding upon and be enforceable by, any successor,
          surviving or resulting corporation, or other entity to which such
          assets shall be transferred. This Agreement shall not be terminated by
          the voluntary or involuntary dissolution of the Company.

     b.   This Agreement and the rights of Executive with respect to the
          benefits of employment referred to in Paragraph 4c hereof constitute
          the entire agreement between the parties hereto in respect of the
          employment of Executive by the Company. This Agreement supersedes and
          replaces all prior oral and written agreements, understandings,
          commitments, and practices between Executive and either GMI or the
          Company; provided, however, that nothing herein shall relieve
                   --------- --------                                  
          Executive from his obligation to repay any borrowings from the Company
          pursuant to the terms and conditions of such borrowings.

 
     c.   The provisions of this Agreement and parts thereof shall be regarded
          as divisible, and if any of said provisions or any part thereof are
          declared invalid or unenforceable by a court of competent
          jurisdiction, the validity and enforceability of the remainder of such
          provisions or parts thereof and the application thereof shall not be
          affected thereby.

     d.   This Agreement may not be amended or modified except by a written
          instrument executed by the Company and Executive.

     e.   This Agreement and the rights and obligations hereunder shall be
          governed by and construed in accordance with the laws of the
          Commonwealth of Virginia. The parties agree that any dispute related
          to or involving this Agreement will be litigated in a state or federal
          court of competent jurisdiction in the Commonwealth of Virginia.

     f.   If this Agreement is executed after the commencement of Executive's
          employment with the Company, Executive acknowledges and agrees that
          this Agreement is supported by new, additional consideration, the
          receipt and adequacy of which are hereby acknowledged by Executive.

     g.   In the event that any of the provisions of this Agreement are
          determined by a court of competent jurisdiction to be contrary to any
          applicable statute, law, rule or regulations, or to be or any reason
          unenforceable as written, Executive expressly agrees that such court
          may modify this Agreement or any of its terms so as to permit the
          enforcement thereof as thus modified. In the event that any of the
          provisions of this Agreement should ever be deemed to exceed the time,
          geographic area, or activity limitations permitted by applicable law,
          the parties agree that such provisions should be and are reformed to
          the maximum time, geographic area and activity limitations permitted
          by applicable law, and the parties expressly authorize a court having
          jurisdiction to reform the provisions to the maximum time, geographic
          area and activity limitations permitted by applicable law.
