payment which Employee was receiving immediately prior to the termination, until

<PAGE>
 
    (h)  that, during the period during which Employee is employed
by Employer, he will not, without the prior written consent in each case of the
Board of Directors of Employer: (i) participate actively in any other business
interests or investments which would conflict with his responsibilities under
this Agreement, or (ii) borrow money from, or lend to, customers (except those

operation of the covenants contained in this Section 4, upon the termination of

  Section 5.  Injunctive Relief.  Because the services to be performed
  -----------------------------                                       
by Employee hereunder are of a special, unique, unusual, confidential
extraordinary and intellectual character which character renders such services
unique and because Employee will acquire by reason of his employment and
association with Employer an extensive knowledge of Employer's trade secrets,
customers, procedures, and other confidential information, the parties hereto
recognize and acknowledge that, in the event of a breach or threat of breach by
Employee of any of the terms and provisions contained in Section 4 or Section 7
of this Agreement, monetary damages alone to Employer would not be an adequate
remedy for a breach of any of such terms and provisions.  Therefore, it is
agreed that in the event of a breach or threat of a breach of any of the
provisions of Section 4 or Section 7 of this Agreement by Employee, Employer
shall be entitled to an immediate injunction from any court of competent
jurisdiction restraining Employee, as well as any third parties including
successor employers of Employee whose joinder may be necessary to effect full
and complete relief, from committing or continuing to commit a breach of such
provisions without the showing or proving of actual damages.  Any preliminary
injunction or restraining order shall continue in full force and effect until
any and all disputes between the parties to such injunction or order regarding
this Agreement have been finally resolved.  Employee hereby agrees to pay all
costs of suit incurred by Employer, including but not limited to reasonable
attorneys' fees, in obtaining any such injunction or order.  Employee hereby
waives any right he may have to require Employer to post a bond or other
security with respect to obtaining or continuing any such injunction or
temporary restraining order and, further, hereby releases Employer, its
officers, directors, employees and agents from and waives any claim for damages
against them which he might have with respect to Employer obtaining in good
faith any injunction or restraining order pursuant to this Agreement.

  Section 6.  Absence of Restrictions. Employee hereby represents and
  -----------------------------------                                
warrants that he has full power, authority and legal right to enter into this
Agreement and to carry out his obligations and duties hereunder and that the
execution, delivery and performance by Employee of this Agreement will not
violate or conflict with, or constitute a default under, any agreements or other
understanding to which Employee is a party or by which he may be bound or
affected, including but not limited to, any order, judgment or decree of any
court or governmental agency.

  Section 7.  Patents and Inventions.  Employee will promptly submit to
  ----------------------------------                                   
Employer written disclosures of all inventions, improvements, discoveries and
new ideas, relating to Employer's business, whether or not patentable
(hereinafter called "Inventions"), which are made or conceived by Employee,
alone or jointly with others, during the period during which Employee is
employed by Employer.  Title to all such Inventions that shall be within the
existing or contemplated scope of Employer's business at the time such
Inventions are made or conceived or which result from or are suggested by any
work Employee or others may do for or on behalf of Employer, together with such
patent, patents or other legal protection as may be obtained thereon in the
United States of America and all foreign countries, shall belong to Employer.
Employee will assign any rights or interest in such title to Employer, and upon
the request of Employer, will at any time during the period during which
Employee is employed by Employer and after termination of Employee's employment
for any reason, execute all proper papers for use in applying for, obtaining,
maintaining and enforcing such patents or other legal protection as Employer may
desire and will execute and deliver all proper assignments thereof, when so
requested, without remuneration but at the expense of Employer.

a court of competent jurisdiction because of time limitation or geographical
area therein provided, such provisions shall nevertheless be effective and
enforceable for such period of time and/or such geographical area as may be held
to be reasonable by such court.  Any provision of this Agreement that is
invalid, illegal or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such invalidity, illegality or
unenforceability without invalidating or rendering unenforceable the remaining
