     salary during Sick Leave and will be deemed to be on leave, without pay,
     during the Disability Period. If Employee is unable to work for a period in
     excess of 90 days, Employee, at the discretion of the Board of Directors of
     company, will be considered to have resigned. In no event will Employee be
     entitled to payment or other compensation for unused Sick Leave or
     Disability Period, unless required by law or otherwise provided in a policy
     or employment manual adopted by Company.

5.   RESIGNATION AND DISCHARGE. Employee may resign or be discharged pursuant to

     Employee.

     For purposes of this paragraph, "for cause" means that during the
     Employment Period, Employee, unless otherwise provided by Company policy or
     Company employment manual, (a) is reasonably believed by Company (i) to
     have failed to comply with any law, regulation or policy, including without
     limitation securities or employment or non-discrimination or similar laws,
     regulations or policies, and that failure causes a significant financial,
     regulatory, operational or public perception detriment to Company, (ii) to

     committed or is charged with any felony or misdemeanor involving moral
     turpitude, or (d) through willful neglect, gross negligence, or malfeasance

     perception detriment to Company. A determination by the Board of Directors
     that Employee has

PAGE 2
<PAGE>   3

     failed to perform Employee's responsibilities to the satisfaction of the
     Board of Directors, without one or more of the other elements set out in
     this paragraph, is not "for cause".

6.   COMPETITION AND CONFIDENTIAL INFORMATION RESTRICTIONS.

     A.   COMPETITION RESTRICTIONS. Employee may not during the Employment
          Period, and for a period of two years following the termination of the
          Employment Period, anywhere in the United States, directly or
          indirectly, own, manage, operate, invest in, control, be employed by,
          participate in, be a financial sponsor of, or be connected in any
          manner with the ownership, management, operation or control of any
          business that competes with a business conducted by Company at any
          time during the Employment Period or which Employee knows, during the
          Employment Period, that Company intends to conduct. Employee
          acknowledges that this restriction is necessary for Company's welfare
          and protection in light of the responsibilities assigned to Employee
          and Employee's status in Company, that Employee is fully and
          adequately compensated for this restriction.

     B.   CONFIDENTIAL INFORMATION. Employee acknowledges and recognizes that
          Employee is, or will be, employed by Company in a confidential
          relationship and may receive and have access to the confidential
          business information, customer names, contracts and other customer
          data, business methods, techniques and trade secrets of Company
          ("Confidential Information"). Employee may develop ideas, conceptions,
          inventions, processes, methods, products and improvements; and
          Employee may receive disclosures of ideas, conceptions, inventions,
          processes, methods, products and improvements made by other employees
          of Company ("Company Inventions"). Employee may participate with
          Company in improving and developing Confidential Information and
          Company Inventions. Confidential Information and Company Inventions
          developed on behalf of Company are neither commonly known nor readily
          accessible to others and are used by Company in its business to obtain
          a competitive advantage over Company's competitors who do not know or
          use the Confidential Information or Company Inventions. Protection of
          the Confidential Information and Company Inventions against
          unauthorized disclosure and use is of critical importance to Company
          in maintaining its competitive position. Employee agrees that Employee
          will not, at any time, during or after the Employment Period, make any
          independent use of, or disclose to any other

EMPLOYMENT AGREEMENT

          any Confidential Information or Company Inventions. Upon termination
          of the Employment Period for any reason, Employee shall promptly
          deliver to Company all drawings, manuals, letters, notes, notebooks,
          reports, customer lists, customer data, mailing lists, and all other
          materials and records of any kinds, and all copies thereof, that may
          be in the possession of, or under the control of, Employee pertaining
          to Company's business including any that contain any Confidential
          Information or Company Invention.

     C.   BUSINESS RELATIONSHIPS. Employee acknowledges Company's efforts to
          establish valuable business relationships with its clients, customers
          and suppliers. Employee recognizes that Company has invested resources
          in the training and the professional development of Employee, and
          Employee further recognizes Employee's responsibility to the Company
          when Company entrusts Employee with Confidential Information. In view
          of Company's efforts, Employee agrees that unless Company authorizes
          Employee to do so in writing, Employee will not, for a period of one
          year after termination of employment with Company, solicit the
          purchase of products or services directly competing with products and
          services of Company from any person, corporation, business
          organization or enterprise which: (i) has made any purchase of
          products or services from Company within the two years immediately
          preceding termination of former Employee's employment ("Customer"); or
          (ii) has been contacted by Employee during the last 12 months of
          Employee's employment for the purpose of securing the purchase of
          products or services from Company ("Prospective Customer").

     D.   NON-SOLICITATION OF EMPLOYEES. Employee is aware that Company has a
          significant investment in its employees. For a period of twelve months
          after termination for any reason of Employee's employment, neither
          Employee nor any person or entity by whom Employee may be employed or
          of which Employee may be an officer, director, partner, trustee or
          control person, will directly or indirectly employ or solicit to
          employ, or otherwise retain or solicit to retain, any person employed
          by Company as of the date of Employee's termination of employment or
          during the twelve month period thereafter, unless that person has been
          terminated by Company without cause (as determined in good faith by
          Company) before the time of the solicitation, employment or retention.

     E.   REMEDIES. Employee and Company recognize that irreparable injury may
          result to Company in the event of breach or threatened breach of this

          or threatens to commit a breach of any of the provisions of this
          paragraph, Company shall have the right and remedy, in addition to any
          others that may be available, at law or in equity, to have the
          provisions of this paragraph specifically enforced by any court having
          equity jurisdiction, together with an accounting therefor, Employee
          having specifically acknowledged that any such breach or threatened
          breach will cause irreparable injury to Company and that money damages
          will not provide an adequate remedy to Company.

     construed to be unenforceable or invalid, the remaining provisions shall
     not be affected but shall continue in full effect. If any term of this

     having jurisdiction, that court shall have the power to reduce or revise
     the term and the paragraph(s) shall then be fully enforceable.

8.   ASSIGNMENT. Employee acknowledges that Employee's services are unique and
     personal. Accordingly, Employee may not assign Employee's rights or
     delegate Employee's duties or obligations under this Agreement. The
     Employer's rights and obligations shall inure to the benefit of and shall
     be binding upon Employer's successor and assigns.

     Company's employees, including Employee, and describe additional terms and
