         6. Former Employers. Employee represents that the execution and
delivery of this Agreement and Employee's employment with the Company does not
violate any previous employment agreement or other contractual obligation of
Employee. Employee represents and agrees that any and all employment agreements
to which Employee is or was a party (the "Employment Agreements") have been
terminated and Employee has obtained releases with respect to said Employment
Agreements. Employee also represents and agrees that Employee has not used or
disclosed, and will not use or disclose, to the Company any information, whether
confidential, proprietary, or otherwise, which Employee has in Employee's
possession and which Employee is not legally free to use or disclose.

condition to Employee's employment that he will never disclose, directly or
indirectly, to any other firm or person any of Company's or its Affiliates'
confidential or proprietary information including customer lists, trade secrets,
and know-how relating to its or their business. Confidential or proprietary
information shall not include any information which is or hereafter comes in the
public domain or is or becomes generally known or available in the industry
through no act of Employee prohibited by this Agreement.

         8. Non-Compete and Non-Solicitation Agreement.

                  8.1 Employee recognizes that (a) the Company and its
Affiliates have spent substantial money, time and effort developing and
solidifying their relationships with their customers and in developing their
confidential information; (b) customer relationships have been difficult to
develop and required a significant investment of Company time, effort and
expense; (c) the Company pays its employees to, among other things, develop and
preserve business information, customer goodwill and customer loyalty for and on
behalf of the Company; and (d) the Company is hereby agreeing to employ and pay
Employee based upon Employee's assurances and promises contained herein not to
misappropriate the goodwill of the Company's customers and not to put herself in
a position during or following Employee's employment with the Company in which
the confidentiality of the Company's confidential and proprietary information as
described in Section 7 might somehow be compromised. Accordingly, Employee
covenants and agrees that for a period ending on the later of (i) two years from
the date hereof or (ii) one year after termination of Employee's employment
hereunder (the "Non-Compete Period"), regardless of whether Employee's
termination of employment, if any, is with or without cause, neither Employee
nor any entity controlled by or under common control with Employee shall (x)
engage in, or have any direct or indirect interest in any other person, firm,
corporation, or other entity engaged in any material business activities engaged
in by the Company on the Date of Termination, or (y) become an employee,
director, advisor, consultant, independent contractor, or agent of any such
person, firm, corporation or other entity, except with the Company's prior
written consent.

   7

                  8.2 Employee further covenants that he shall not (a) solicit,
cause or induce or attempt to solicit, cause or induce any present or future
employee of the Company or its Affiliates (i.e., any person employed by the
Company or its Affiliates (or their successors) at any time from and including
the date hereof through the Date of Termination) to leave the employ of the
Company or its Affiliates (or their successors), (b) cause or induce or attempt
to cause or induce any present or future client ("Present or Future Client") of
the Company or its Affiliates (or their successors) (i.e., any person or entity
which is a client of the Company or its Affiliates (or their successors) at any
time from and including the date hereof through the Date of Termination) to
reduce or sever its affiliation with the Company or its Affiliates (or their
successors) with respect to a material business of the Company or its Affiliates
engage in on the Date of Termination, or (c) solicit, attempt to solicit or
accept business relating to the material business of the Company or its
Affiliates engaged in by the Company on the Date of Termination from any Present
or Future Client of the Company or its Affiliates (or their successors).

                  8.3 Employee recognizes and agrees that the restraints
contained in Sections 8.1 and 8.2 are reasonable and enforceable in view of the
legitimate interests of the Company and its Affiliates in protecting their
confidential information and customer goodwill, and that the limitations
contained therein on the duration and geographic scope of, and activities
prohibited by, such restraints are reasonable and binding upon Employee.

                  8.4 The covenants contained in this Section 8 shall be deemed
to be a series of separate covenants, one for each aspect of the Company's
businesses and locations. Each separate covenant shall hereinafter be referred
to as a "Separate Covenant."

                  8.5 If any court or tribunal of competent jurisdiction shall
refuse to enforce one or more of the Separate Covenants because the time limit
applicable thereto is deemed unreasonable, it is expressly understood and agreed
that such Separate Covenant or Separate Covenants shall not be void but that for
the purpose of such proceedings such time limitation shall be deemed to be
reduced to the extent necessary to permit the enforcement of such Separate
Covenant or Separate Covenants.

                  8.6 If any court or tribunal of competent jurisdiction shall
refuse to enforce any or all of the Separate Covenants because, taken together,
they are more extensive (whether as to geographic area, scope of business, or
otherwise) than is deemed to be reasonable, it is expressly understood and
agreed between the parties that such Separate Covenant or Separate Covenants
shall not be void but that for the purpose of such proceedings the restrictions
contained therein (whether as to geographic area, scope of business or
otherwise) shall be deemed to be reduced to the extent necessary to permit the
enforcement of such Separate Covenant or Separate Covenants.

                  8.7 Nothing contained herein shall restrict Employee from
owning 5% or less of the corporate securities of any entity in competition with
the Company's businesses,


                                        7
   8

which securities are listed on any national securities exchange or authorized
for listing on the NASDAQ National Market, if Employee has no other connection
or relationship, direct or indirect, with the issuer of such securities.

         9. Survival. Employee's obligations under the provisions of Sections 7,
8, 9, 10 and 14 of this Agreement (as modified by Section 10, if applicable)
shall survive the expiration or termination of Employee's employment (whether
through Employee's resignation or otherwise) with the Company.

         10. Assignment. This Agreement and the rights and obligations of the
parties hereto shall bind and inure to the benefit of any successor or
successors of the Company by reorganization, merger or consolidation and any
assignee of all or substantially all of its business and properties.
Notwithstanding any other provision of this Agreement, and properties, but,
except as to any such successor or assignee of the Company, neither this
Agreement nor any rights or benefits hereunder may be assigned by the Company or
by Employee.

         11. Interpretation. IT IS THE INTENT OF THE PARTIES THAT in case any
one or more of the provisions contained in this Agreement shall, for any reason,
be held to be invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect the other provisions of this
Agreement, and this Agreement shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein. MOREOVER, IT IS THE
INTENT OF THE PARTIES THAT in case any one or more of the provisions contained
in this Agreement shall for any reason be held to be excessively broad as to
duration, geographical scope, activity or subject, such provision shall be
construed by limiting and reducing it as determined by a court of competent
jurisdiction, so as to be enforceable to the extent compatible with applicable
law.

         12. Notices. Any notice which the Company is required or may desire to
give Employee shall be given by personal delivery or registered or certified
mail, return receipt requested, addressed to Employee at Employee's address of
record with the Company, or at such other place as Employee may from time to
time designate in writing. Any notice which Employee is required or may desire
to give to the Company hereunder shall be given by personal delivery or by
registered or certified mail, return receipt requested, addressed to the Company
at its principal office, or at such other office as the Company may from time to
time designate in writing. The date of personal delivery or the date of mailing
any notice under this Section 11 shall be deemed to be the date of delivery
thereof.

         13. Waivers. If either party should waive any breach of any provision
of this Agreement, such party shall not thereby be deemed to have waived any
preceding or succeeding breach of the same or any other provision of this
Agreement.

         14. The Company's Right to Injunctive Relief. In the event of a breach
or threatened breach of any of Employee's duties and obligations under the terms
and provisions of Sections 7 or 8 hereof, the Company shall be entitled, in
addition to any other legal or equitable remedies it may have (including any
right to damages that it may suffer), to temporary, preliminary, and permanent
injunctive relief restraining such breach or threatened breach. Employee hereby
expressly acknowledges that the harm which might result to the Company's
business as a result of any noncompliance by Employee with any of the provisions
of Sections 7 or 8 hereof would be largely irreparable.
