6.2 DEFINITION OF DISABILITY

For purposes of Section 6.1, the Executive will be deemed to have a
"disability" if, for physical or mental reasons, the Executive is unable to
perform the Executive's duties under this Agreement for 120 consecutive days,
or 180 days during any twelve month period, as determined in accordance with
this Section 6.2. The disability of the Executive will be determined by a

will select a medical doctor and the two medical doctors will select a third
medical doctor who will determine whether the Executive has a disability. The
determination of the medical doctor selected under this Section 6.2 will be
binding on both parties. The Executive must submit to a reasonable number of
examinations by the medical doctor making the determination of disability
under this Section 6.2, and the Executive hereby authorizes the disclosure and
release to the Employer of such determination and all supporting medical
records. If the Executive is not legally competent, the Executive's legal
guardian or duly authorized attorney-in-fact will act in the Executive's stead,
under this Section 6.2, for the purposes of submitting the Executive to the
examinations, and providing the authorization of disclosure, required under this
Section 6.2.

6.3 DEFINITION OF "FOR CAUSE"

For purposes of Section 6.1, the phrase "for cause" means: (a) the Executive's
breach of this Agreement (b) the Executive's failure to adhere to any written
Employer policy if the Executive has been given a reasonable opportunity to

opportunity must be granted during the ten-day period preceding termination of
this Agreement); (c) the appropriation (or attempted appropriation) of a
material business opportunity of the Employer, including attempting to secure
or securing any personal profit in connection with any transaction entered into
on behalf of the Employer; (d) the misappropriation (or attempted
misappropriation) of any of the Employer's funds or property; or (e) the
conviction of, the indictment for (or its procedural equivalent), or the
entering of a guilty plea or plea of no contest with respect to, a felony, the
equivalent thereof, or any other crime with respect to which imprisonment is a
possible punishment.
<PAGE>   6


6.4 DEFINITION OF "FOR GOOD REASON"

For purposes of Section 6.1, the phrase "for good reason" means any of the
following: (a) the Employer's material breach of this Agreement; (b) the
assignment of the Executive without his consent to a position,
responsibilities, or duties of a materially lesser status or degree of
responsibility than his position, responsibilities, or duties at the Effective
Date; or (c) the requirement by the Employer that the Executive be based
anywhere other than the Employer's principal executive offices, in either case
without the Executive's consent. 

6.5 TERMINATION PAY

Effective upon the termination of this Agreement, the Employer will be  
obligated to pay the Executive (or, in the event of his death, his designated
beneficiary as defined below) only such compensation as is provided in this
Section 6.5, which compensation shall be in lieu of all other amounts and in
settlement and complete release of all claims the Executive may have against
the Employer. For purposes of this Section 6.5, the Executive's designated
beneficiary will be  such individual beneficiary or trust, located at such
address, as the Executive may designate by notice to the Employer from time to
time or, if the Executive fails to give notice to the Employer of such a
beneficiary, the Executive's estate. Notwithstanding the preceding sentence,
the Employer will have no duty, in any circumstances, to attempt to open an
estate on behalf of the Executive, to determine whether any beneficiary
designated by the Executive is alive or to ascertain the address of any such
beneficiary, to determine the existence of any trust, to determine whether any
person or entity purporting to act as the Executive's personal representative
(or the trustee of a trust established by the Executive) is duly authorized to
act in that capacity, or to locate or attempt to locate any beneficiary,
personal representative, or trustee. 

        (A)     Termination by the Executive for Good Reason.  If the Executive
terminates this Agreement for good reason, the Employer will pay the
Executive's Salary for the remainder, if any, of the Employment Period as if
this Agreement had not terminated, provided, however, that Incentive
Compensation pursuant to Sections 3.2(A) and (B) shall be payable if, as of the
date of termination, there is then pending before the Bankruptcy Court a Plan
of Reorganization which is thereafter confirmed by such Court. 

        (B)     Termination by the Employer for Cause.  If the Employer
terminates this Agreement for cause, the Executive will be entitled to receive
his Salary only through the date such termination is effective, but will not be
entitled to any Incentive Compensation for the Fiscal Year during which such
termination occurs or any subsequent Fiscal Year. 

        (C)     Termination upon Disability.  If this Agreement is terminated
by either party as a result of the Executive's disability, as determined under
Section 6.2, the Employer will pay the Executive his Salary through the
remainder of the calendar month during which such termination is effective and
for the lesser of (i) the remainder, if any, of the Employment Period, or (ii)
the period until disability insurance benefits commence under the disability
insurance coverage furnished by the Employer to the Executive. However, the
Executive will not be entitled to any Incentive Compensation for any period
subsequent to the date on which termination is effective, provided, however,
that Incentive Compensation pursuant to Sections 3.2(A) and (B) shall be
payable if, as of the date of termination,

there is then pending between the Bankruptcy Court a Plan of Reorganization
which is thereafter confirmed by such Court.

        (D)  Termination upon Death. If this Agreement is terminated because of
the Executive's death, the Executive will be entitled to receive his Salary
through the end of the calendar month in which his death occurs. However, the
Executive will not be entitled to any Incentive Compensation for any period
subsequent to the date on which termination is effective, provided, however,
that Incentive Compensation pursuant to Sections 3.2(A) and (B) shall be
payable if, as of the date of termination, there is then pending before the
Bankruptcy Court a Plan of Reorganization which is thereafter confirmed by such
Court.

        (E)  Benefits. The Executive's accrual of, or participation in plans
providing for, the Benefits will cease at the effective date of the termination
of this Agreement, and the Executive will be entitled to accrued Benefits
pursuant to such plans only as provided in such plans. The Executive will not
receive, as part of his termination pay pursuant to this Section 6, any payment
or other compensation for any vacation, holiday, sick leave, or other leave
unused on the date the notice of termination is given under this Agreement.


================================================================================
7.  NON-DISCLOSURE COVENANT

7.1  ACKNOWLEDGEMENTS BY THE EXECUTIVE

of his employment, the Executive will be afforded access to Confidential
Information; (b) public disclosure of such Confidential Information could have
an adverse effect on the Employer and its business; (c) the Employer has
required that the Executive make the covenants in this Section 7 as a condition
to its employment of the Executive, and (d) the provisions of this Section 7
are reasonable and necessary to prevent the improper use or disclosure of
Confidential Information.

In consideration of the compensation and benefits to be paid or provided to the

follows:

        (A)     Confidentiality.

                (i)  During and following the Employment Period, the Executive
will hold in confidence the Confidential Information and will not disclose it
to any person except with the specific prior written consent of the Employer or
except as otherwise expressly permitted by the terms of this Agreement.

                (ii) Any trade secrets of the Employer will be entitled to all
of the protections and benefits under applicable state or federal trade secret
law and any other applicable law. If any information that the Employer deems to
be a trade secret is found by a court of competent jurisdiction not to be a
trade secret for purposes of this Agreement, such information will,
nevertheless, be




                                      7

                
<PAGE>   8

Executive hereby waives any requirement that the Employer submit proof of the
economic value of any trade secret or post a bond or other security.

        (iii) None of the foregoing obligations and restrictions applies to any
part of the Confidential Information that the Executive demonstrates was or
became generally available to the public other than as a result of a disclosure
by the Executive.

        (iv) The Executive will not remove from the Employer's premises (except
to the extent such removal is for purposes of the performance of the
Executive's duties at home or while traveling, or except as otherwise
specifically authorized by the Employer) any document, record, notebook, plan,
model, component, device, or computer software or code, whether embodied in a
disk or in any other form (collectively, the "Proprietary Items"). The
Executive recognizes that, as between the Employer and the Executive, all of
the Proprietary Items, whether or not developed by the Executive, are the
exclusive property of the Employer. Upon termination of this Agreement by
either party, or upon the request of the Employer during the Employment Period,
the Executive will return to the Employer all of the Proprietary Items in the
Executive's possession or subject to the Executive's control, and the Executive
shall not retain any copies, abstracts, sketches, or other physical embodiment
of any of the Proprietary Items.

7.3 DISPUTES OR CONTROVERSIES

The Executive recognizes that should a dispute or controversy arising from or
relating to this Agreement be submitted for adjudication to any court,
arbitration panel, or other third party, the preservation of the secrecy of
Confidential Information may be jeopardized. All pleadings, documents,
testimony, and records relating to any such adjudication will be maintained in
secrecy and will be available for inspection by the Employer, the Executive,
and their respective attorneys and experts, who will agree, in advance and in
writing to receive and maintain all such information in secrecy, except as may
be limited by them in writing.

===============================================================================

                                       8
<PAGE>   9
8.2 COVENANTS OF THE EXECUTIVE

The parties hereto agree that the covenants, agreements and restrictions
(hereinafter "this covenant") contained herein are necessary to protect the
business goodwill, business interests and proprietary rights of the Employer
and that the parties hereto have independently discussed, reviewed and had the
opportunity of legal counsel to consider this agreement and now hereby agree
and stipulate the following:

        (a)  This covenant is an integral part of an enforceable employment
agreement and the covenants contained herein were made at the time this
agreement was consummated by the parties hereto.

        (b)  This covenant is fair and reasonable in its:
                1. geographical area;
                2. length of time; and
                3. scope of activity being restrained.

In consideration of the acknowledgments by the Executive, and in consideration
of the compensation and benefits to be paid or provided to the Executive by the
Employer, the Executive covenants that he will not, directly or indirectly:

        (a)  during the Employment Period, except in the course of his
employment hereunder or as provided in Exhibit A to this Agreement, engage or
invest in, own, manage, operate, finance, control, or participate in the
ownership, management, operation, financing, or control of, be employed by,
associated with, or in any manner connected with, lend the Executive's name or
any similar name to, lend Executive's credit to or render services or advice
to, any business whose products or activities compete in whole or in part with
the products or activities of the Employer anywhere within the United States;
provided, however, that the Executive may purchase or otherwise acquire up to
(but not more than) 4.9% of any class of securities of any enterprise (but
without otherwise participating in the activities of such enterprise) if such
securities are listed on any national or regional securities exchange or have
been registered under Section 12(g) of the Securities Exchange Act of 1934;

        (b)  whether for the Executive's own account or for the account of any
other person, at any time during the Employment Period solicit business of the
same or similar type being carried on by the Employer, from any person known by
the Executive to be a customer of the Employer, whether or not the Executive
had personal contact with such person during and by reason of the Executive's
employment with the Employer; or

        (c)  at any time during or after the Employment Period, disparage the
Employer or any of its shareholders, directors, officers, employees, or agents.

        The parties hereby agree and acknowledge that the Employer has spent
considerable sums of money and time in developing good customer contact and
rapport and that the client list or customer list developed by the Employer is
worth a considerable amount of money and therefore is a benefit which the
Employer seeks to protect. Such protection is hereby agreed and acknowledged by
both parties as being reasonable consideration for establishing this
restrictive covenant.






                                       9
<PAGE>   10
        If any covenant in this Section 8.2 is held to be unreasonable,
arbitrary, or against public policy, such covenant will be considered to be
divisible with respect to scope, time, and geographic area, and such lesser
scope, time, or geographic area, or all of them, as a court of competent
jurisdiction may determine to be reasonable, not arbitrary, and not against
public policy, will be effective, binding, and enforceable against the
Executive.

        The period of time applicable to any covenant in this Section 8.2 will
be extended by the duration of any violation by the Executive of such covenant.

        The Executive will, while the covenant under this Section 8.2 is in
effect, give notice to the Employer, within ten days after accepting any other
employment, of the identity of the Executive's employer. The Employer may
notify any such subsequent employer that the Executive is bound by this
Agreement and, at the Employer's election, furnish such employer with a copy of
this Agreement or relevant portions thereof.

================================================================================
9. GENERAL PROVISIONS

9.1 INJUNCTIVE RELIEF AND ADDITIONAL REMEDY

The Executive acknowledges that the injury that would be suffered by the
Employer as a result of breach of the provisions of this Agreement (including
any provision of Sections 7 and 8) would be irreparable and that an award of
monetary damages to the Employer for such a breach would be an inadequate
remedy. Consequently, the employer will have the right, in addition to any
other rights it may have, to obtain injunctive relief to restrain any breach or
threatened breach or otherwise to specifically enforce any provision of this
Agreement, and the Employer will not be obligated to post bond or other
security in seeking such relief. Without limiting the Employer's rights under
this Section 9 or any other remedies of the Employer, if the Executive breaches
any of the provisions of Section 7 or 8, the Employer will have the right to
cease making any payments otherwise due to the Executive under this Agreement.

9.2 COVENANTS OF SECTIONS 7 AND 8 ARE ESSENTIAL AND INDEPENDENT COVENANTS

The covenants by the Executive in Sections 7 and 8 are essential elements of
this Agreement, and without the Executive's agreement to comply with such
covenants, the Employer would not have entered into this Agreement or employed
or continued the employment of the Executive. The Employer and the Executive
have independently consulted their respective counsel and have been advised in
all respects concerning the reasonableness and proprietary of such covenants,
with specific regard to the nature of the business conducted by the Employer.

        The Executive's covenants in Sections 7 and 8 are independent covenants
and the existence of any claim by the Executive against the Employer under this
Agreement or otherwise will not excuse the Executive's breach of any covenant
in Section 7 or 8.





                                       10
<PAGE>   11
        If the Executive's employment hereunder expires or is terminated, this
Agreement will continue in full force and effect as is necessary or appropriate
to enforce the covenants and agreements of the Executive in Sections 7 and 8.

9.3     OFFSET

The Employer will be entitled to offset against any and all amounts owing to
the Executive under this Agreement the amount of any and all valid claims that
the Employer may have against the Executive under the Noncompetition Agreement.

9.4   REPRESENTATIONS AND WARRANTIES BY THE EXECUTIVE    

The Executive represents and warrants to the Employer that the execution and
delivery by the Executive of this Agreement do not, and the performance by the
Executive of the Executive's obligations hereunder will not, with or without
the giving of notice or the passage of time, or both: (a) violate any judgment,
writ, injunction, or order of any court, arbitrator, or governmental agency
applicable to the Executive, or (b) conflict with, result in the breach of any
provisions of or the termination of, or constitute a default under, any
agreement to which the Executive is a party or by which the Executive is or may
be bound.

9.5  OBLIGATIONS CONTINGENT ON PERFORMANCE      

The obligations of the Employer hereunder, including its obligation to pay the
compensation provided for herein, are contingent upon the Executive's
performance of the Executive's obligations hereunder. 

9.6  WAIVER

The rights and remedies of the parties to this Agreement are cumulative and not
alternative. Neither the failure nor any delay by either party in exercising
any right, power, or privilege under this Agreement will operate as a waiver of
such right, power, or privilege, and no single or partial exercise of any such
right, power, or privilege will preclude any other or further exercise of such
right, power, or privilege or the exercise of any other right, power or
privilege. To the maximum extent permitted by applicable law, (a) no claim or
right arising out of this Agreement can be discharged by one party, in whole or
in part, by a waiver or renunciation of the claim or right unless in writing
signed by the other party; (b) no waiver that may be given by a party will be
applicable except in the specific instance for which it is given; and (c) no
notice to or demand on one party will be deemed to be a waiver of any
obligation of such party or of the right of the party giving such notice or
demand to take further action without notice or demand as provided in this
Agreement. 

9.7  BINDING EFFECT; DELEGATION OF DUTIES PROHIBITED

This Agreement shall inure to the benefit of, and shall be binding upon, the
parties hereto and their respective successors, assigns, heirs, and legal
representatives, including any entity with which the Employer may merge or
consolidate or to which all or substantially all of its assets may be
transferred. The duties and covenants of the Executive under this Agreement,
being personal, may not be delegated.
