     contract with a previous employer or with any other business that might
     prevent Executive from entering into this Agreement or disclosing
     information about any previous employer or any other business to Company,
     or might otherwise interfere with Executive's employment hereunder; with
     the exception that Executive acknowledges that his former employer, ISS,
     Inc., allows that Executive is free to enter the employ of a competitor,
     but contends that Executive continues to be bound, until June 27, 1997
     under the provisions of a prior employment agreement which provides:
     
     (i)  that until such time, Executive shall not directly or indirectly
          solicit any of the customers served by ISS, Inc., at the time of
          Executive's termination of employment with ISS, Inc., nor solicit any
          person to leave the employ of ISS, Inc., or any of its subsidiaries;
          and 
     
     (ii) that Executive will not divulge any confidential information of ISS,
          Inc.

     Company and Executive agree that Executive shall not take any action while

     provisions of (i) or (ii) above.
     
J.   COMPANY PROPERTY:  Company shall, from time to time, entrust to the care,
     custody and control of Executive certain of Company's property, such as
     motor vehicles, equipment, supplies and documents.  Such documents may
     include but shall not be limited to customer lists, financial statements,
     cost data, price lists, invoices, forms, mailing lists, contracts, reports,
     manuals, personnel files or directories, correspondence, business cards,
     copies or notes made from Company documents and documents compiled or
     prepared by Executive for Executive's use in connection with Company
     business.  Executive specifically acknowledges that all such documents are
     the property of Company, notwithstanding their preparation, care, custody,
     control or possession by Executive at any time(s) whatsoever.
     
K.   GOODWILL & PROPRIETARY INFORMATION:  In connection with Executive's
     employment hereunder:
     
     1.   Executive agrees to utilize and further Company's goodwill
          ("Goodwill") among its customers, sales prospects and employees, and
          agrees that Company may disclose to Executive and Executive may
          disclose to Company, proprietary trade secrets and other confidential
          information not in the public domain ("Proprietary Information")
          including but not limited to specific customer data such as: (a) the
          identity of Company's customers and sales prospects, (b) the nature,
          extent, frequency, methodology, cost, price and profit associated with
          their services and products  purchased from Company, (c) any
          particular needs or preferences regarding their service or supply
          requirements, (d) the names, office hours, telephone numbers and
          street addresses of their purchasing agents or other buyers, (e) their
          billing procedures, (f) their credit limits and payment practices and
          (g) their organization structure.
          
     2.   Executive agrees that such Proprietary Information and Goodwill have
          unique value to Company, are not generally known or readily available
          to Company's competitors, and could only be developed by others after
          investing significant time and money.  Company would not make such
          Proprietary Information and Goodwill available to Executive unless
          Company is assured that all such Proprietary Information and Goodwill
          will be held in trust and confidence by Executive.  Executive hereby
          acknowledges that to use this Proprietary Information and Goodwill
          except for the benefit of Company would be improper and unfair to
          Company.
          
L.   RESTRICTIVE COVENANTS:  In recognition of Paragraph K hereof, Executive
     hereby agrees that during the Initial Term and the Extended Term, if any,
     of this Agreement, and thereafter for as long as it shall be enforceable:

     2.   Except in the proper performance of this Agreement, Executive shall

          by Executive from, or for, Company.

          or accept any site-specific customer account or sales prospect of

          full-time employee, with the understanding and agreement that such

          such services by reason of any physical or mental illness or
          disability other than Total Disability or death as set forth in
          Paragraph O3 hereof, or unavailability because of absence from the

INITIALS: EXECUTIVE                        COMPANY

N.   INTENTIONALLY OMITTED

     1.   Termination of employment which either party schedules for the

          cause for termination.

     2.   Except as provided in Paragraph O1 respecting termination, effective
          with or without cause which is scheduled at the expiration of the Term
          or Extended Term, at any time during the Term of this Agreement,
          Company shall have the right to terminate Executive's employment
          hereunder without notice subject only to a good faith determination by
          a majority of the Board of Directors of Company of "just cause."

     4.   Employment hereunder shall automatically terminate upon the total
          disability ("Total Disability") or death of Executive.  Total
          Disability shall be deemed to occur on the ninetieth (90th)
          consecutive or non-consecutive calendar day within any twelve (12)
          month period that Executive is unable to perform the duties set forth
          in Paragraph C hereof because of any physical or mental illness or
          disability.  Company shall pay to Executive or his estate, as
          applicable, all prorated salary, bonus or other contingent
          compensation, reimbursement of business expenses and fringe benefits
          which would have otherwise been payable to Executive under this
          Agreement, through the end of the month in which Total Disability or
          death occurs.
          
     5.   Upon termination of employment hereunder, Executive shall immediately
          resign as an employee of Company and as an officer or director of
          Company, if applicable.  Executive shall promptly return all Company
          property in Executive's possession to Company, including but not
          limited to, any motor vehicles, equipment, supplies and documents set
          forth in Paragraph J hereof.  Company shall pay Executive, when due,
          all previously earned and vested but as yet unpaid salary, prorated
          bonus or other contingent compensation, reimbursement of business
          expenses and fringe benefits.
          
     6.   Nothing contained in this Agreement shall entitle Executive to receive
          a bonus or other

INITIALS: EXECUTIVE                        COMPANY
                    ----------------------          ------------



          incentive or contingent compensation, if any are otherwise payable to
          Executive, from Company based on any sales or profits made by Company
          after termination of employment hereunder.
          
P.   GOVERNING LAW:  This Agreement shall be interpreted and enforced in
     accordance with the laws of the State of Employment hereunder.

Q.   ARBITRATION CLAUSE: 

     1.   Except for the interpretation and enforcement of injunctive relief
          pursuant to Paragraph L hereof (which, at Company's option, shall be
          subject to litigation in any court having proper jurisdiction), any
          claim or dispute related to or arising from this Agreement (whether
          based in contract or tort, in law or equity) including, but not
          limited to,  claims or disputes between Executive and Company or its
          directors, officers, employees and agents regarding Executive's
          employment or termination of employment hereunder, or any other
          business of Company, shall be resolved by mandatory, final, binding
          arbitration in accordance with the rules of the American Arbitration
          Association; provided, however, that no party shall be entitled to an
          award of general or punitive damages hereunder.
          
     2.   Any such arbitration must be requested in writing within one (1) year
          from the date the party initiating the arbitration knew or should have
          known about the claim or dispute, or all claims arising from that
          dispute are forever waived.  Any such arbitration (or court proceeding
          as applicable hereunder) shall be held in the County of Employment. 
          Judgment upon the award rendered through such arbitration may be
          entered and enforced in any court having proper jurisdiction.
          
R.   REMEDIES & DAMAGES:

     1.   The parties agree that, in the event of a material breach or
          threatened breach of Paragraph L hereof, the damage or imminent damage
          to the value of Company's business shall be inestimable, and therefore
          any remedy at law or in damages shall be inadequate.  Accordingly, the
          parties hereto agree that Company shall be entitled to the immediate
          issuance of a restraining order or an injunction against Executive in
          the event of such breach or threatened breach, in addition to any
          other relief available to Company pursuant to this Agreement or under
          law.
          
     2.   Executive agrees that the actual amount of damages resulting from any
          breach of any of the provisions of Paragraph L hereof would be
          impractical or impossible to ascertain.  It is therefore agreed that
          the damages resulting from any such breach which involves any customer
          of Company shall be liquidated damages, not a penalty, in an amount
          equal to four (4) times the lost monthly revenue to the Company based
          on the average monthly revenue which was payable by that customer to
          Company during the four (4) months immediately preceding the breach. 
          This provision for liquidated damages is in addition to any other
          relief available to Company pursuant to this Agreement or under law.
          
     3.   To the full extent permitted under the laws of the State of Employment
          hereunder, Executive authorizes Company to escrow from Executive's
          compensation and from any other funds held for Executive's benefit by
          Company, any damages or losses sustained by Company as a result of any
          breach or other violation of this Agreement by Executive, pending
          arbitration between the parties as provided for herein.
          
S.   NO WAIVER:  Failure by either party to enforce any term or condition of
     this Agreement at any time shall not preclude that party from enforcing
     that provision, or any other provision of this Agreement, at any later
     time.

                    ----------------------          ------------



T.   SEVERABILITY:  The provisions of this Agreement are severable.  If any
     arbitrator (or court as applicable hereunder) rules that any portion of
     this Agreement is invalid or unenforceable, the arbitrator's or court's
     ruling shall not affect the validity and enforceability of other provisions
     of this Agreement.  It is the intent of the parties that if any provision
     of this Agreement is ruled to be overly broad, the arbitrator or court
     shall interpret such provision with as much permissible breadth as is
     allowable under law rather than to consider such provision void.
     
U.   SURVIVAL:  All terms and conditions of this Agreement which by reasonable
     implication are meant to survive the termination of this Agreement,
     including but not limited to, the Restrictive Covenants and Arbitration
     Clause herein, shall remain in full force and effect after the termination
     of this Agreement.
     
V.   CONSTRUCTION:  This Agreement was negotiated in good faith by the parties
     hereto, who hereby agree to share the responsibility for any ambiguities,
     uncertainties or inconsistencies herein.  Paragraph headings are used
     herein only for ease of reference, and shall not in any way affect the
     interpretation or enforcement of this Agreement.
     
W.   NOTICES: 

     1.   Any notice required or permitted to be given pursuant to this
          Agreement shall be in writing and delivered in person, or sent prepaid
          by certified mail, bonded messenger or overnight express, to the party

     1.   The parties intend that this Agreement speak for itself, and that no
          evidence with respect to its terms and conditions other than this
          Agreement itself may be introduced in any arbitration or judicial
          proceeding to interpret or enforce this Agreement.

          provisions of Company's Personnel Policy and Procedures Manual,
          including but not limited to, the termination, discipline and

          Agreement between Executive and Company, nor shall it be binding on
          either party.  The purpose and intent of said Manual are only to
          suggest guidelines for Company managers to apply as they see fit on a
          case by case basis.
