                                    provided, however, purposes of this Section
                                    1(a)(iii), the term "person" will not be
                                    deemed to include any "person" who, as of

                           of business on January 3, 2001, provided, however,
                           unless either the Executive or the Company gives
                           written notice of intent to terminate this Agreement
                           upon the expiration of the first year of this
                           Agreement or any subsequent renewal period, this
                           Agreement will automatically be renewed, upon each
                           anniversary of the date hereof, for successive one
                           year periods ("renewal periods"). Any such notice of
                           termination must be given not less than thirty (30)
                           days prior to the end of the first year of this
                           Agreement or any subsequent renewal period.
                           Notwithstanding the foregoing, the Executive may
                           elect not to renew this Agreement at any time within
                           the fifteen (15) day period immediately following
                           receipt by the Executive of a Compensation Resolution
                           (as hereinafter defined), regardless of whether such
                           Compensation Resolution is delivered before or after
                           any anniversary date of this Agreement. An election
                           not to renew this Agreement will not affect any
                           rights which have vested or otherwise accrued prior
                           to the expiration of this Agreement. The expiration
                           of the Term of this Agreement will not be deemed to
                           be a "termination" of this Agreement for the purposes
                           of Sections 4 and 5.

         2.       Employment. Subject to the terms and conditions of this
Agreement, the Company shall continue the Executive in its employ and the
Executive shall remain in the employ of the Company for the Term, in the
position and with substantially the same duties and responsibilities that the
Executive has as of the date hereof or in the position and with the duties and
responsibilities that the Company and the Executive may hereafter mutually agree
in writing. Throughout the Term, the Executive shall devote substantially all of
the Executive's time during normal business hours (subject to vacations, sick
leave and other absences in accordance with the policies of the Company as in
effect for senior executives as of the date hereof or as otherwise approved by
the Board of Directors of the Company (the "Board")) to the business and affairs
of the Company and shall attempt to maximize stockholder value, but nothing in
this Agreement shall preclude the Executive from devoting reasonable periods of
time during normal business hours to (i) serving as a director, trustee or
member of or participant in any organization or business so long as such
activity does not materially interfere with the performance of the Executive's
obligations pursuant to this Agreement, (ii) engaging in charitable and
community activities, or (iii) managing the Executive's personal investments.

         3.       Compensation During Term. During the Term, the Executive shall
receive an annual base salary (which base salary is herein referred to as "Base
Pay") and shall have the opportunity to earn an annual bonus (the "Annual
Bonus") and may have the opportunity to earn a special bonus (the "Special
Bonus") in each case, in such amounts,



                                      -3-
<PAGE>   4


at such rates, at such times and subject to such conditions as may be determined
annually by the Board pursuant to a formal resolution adopted by the Board
(hereinafter referred to as the "Compensation Resolution"). After delivery of a
copy of the Compensation Resolution (certified by the Secretary of the Company)
to the Executive, the amount, terms and conditions of the Base Pay, Annual Bonus
and Special Bonus (if any) to be earned by and paid to the Executive for the
fiscal year to which the Compensation Resolution relates, may not be amended in
a manner adverse to the Executive without the written consent of the Executive.
The Executive acknowledges the receipt of the Compensation Resolution relating
to the 2000 fiscal year of the Company. The Company will deliver to the
Executive subsequent Compensation Resolutions relating to subsequent fiscal
years of the Company, in a manner consistent with the Company's past
compensation practices. Unless otherwise provided in the applicable Compensation
Resolution, the Executive's Base Pay shall be payable in accordance with the
Company's generally applicable payroll policies and this Agreement. Unless
otherwise provided in the applicable Compensation Resolution, the Executive's
Annual Bonus shall be paid in accordance with the Company's past compensation
practices and this Agreement. Any Special Bonus payable to the Executive shall
be paid in accordance with the terms of the applicable Compensation Resolution
and this Agreement. The Annual Bonus and the Special Bonus are hereinafter
collectively referred to as "Incentive Pay." If this Agreement is "renewed" for
one or more renewal periods (pursuant to Section 2) the Executive's Base Pay for
such renewal period will not be less than the Base Pay payable to the Executive
pursuant to the Compensation Resolution applicable to the immediately preceding
annual period and the target bonus amount with respect to any such renewal
period will be not less than one hundred percent (100%) of the Base Pay payable
with respect to such renewal period.

         4.       Termination.

                  (a)      This Agreement may be terminated by the Company
                           during the Term upon the occurrence of one or more of
                           the following events:

                           (i)      If the Executive is unable to perform the
                                    essential functions of the Executive's
                                    position(s) (with or without reasonable
                                    accommodation) because the Executive has
                                    become Disabled (as hereinafter defined),
                                    and actually begins to receive disability
                                    benefits pursuant to, a long-term disability
                                    plan maintained by or on behalf of the
                                    Company for its employees generally; or

                           (ii)     For "Cause," which for purposes of this
                                    Agreement shall mean:

                                    (A)      the Executive shall have committed
                                             an intentional act of fraud,

                                             connection with the Executive's
                                             duties or in the course of the
                                             Executive's employment with the
                                             Company;

                                    (B)      the Executive shall have been
                                             convicted of felony and the

                                             the Executive with the Company
                                             following such conviction will have

                                             the Company;

                                    (C)      the Executive shall have breached
                                             any material duty of loyalty to the
                                             Company; provided the actions of
                                             the Executive were not approved by
                                             the Board following full disclosure
                                             of the Executive's interest;

                                    (D)      the Executive shall have materially
                                             breached the obligations of the
                                             Executive pursuant to the second
                                             sentence of Section 2;

                                    (E)      the Executive shall have committed
                                             intentional wrongful damage to
                                             property of the Company (which is
                                             materially harmful to the Company);
                                             or

                                             information of the Company (which
                                             is materially harmful to the
                                             Company).

Notwithstanding the foregoing, the Company's right to terminate this Agreement
with respect to any action of the Executive described in Section 4(a)(ii) will
be deemed to have been irrevocably waived by the Company, if the Company does
not terminate this Agreement within sixty (60) days following the Board first
being made aware of such action of the Executive. For purposes of this
Agreement, no act, or failure to act, on the part of the Executive shall be
deemed "intentional" if it was due primarily to an error in judgment or
negligence, but shall be deemed "intentional" only if done, or omitted to be
done, by the Executive not in good faith and without reasonable belief that the
Executive's action or omission was in the best interest of the Company.
Notwithstanding the foregoing, this Agreement shall not be deemed to have been
terminated for "Cause" hereunder unless and until there shall have been
delivered to the Executive a copy of a resolution duly


                                      -5-

adopted by the affirmative vote of not less than a majority of the Board then in
office at a meeting of the Board called and held for such purpose (after
reasonable notice to the Executive and an opportunity for the Executive,
together with the Executive's counsel, to be heard before the Board), finding
that, in the good faith opinion of the Board, the Executive has committed an act
set forth above in this Section 4(a)(ii) and specifying the particulars thereof
in detail. Nothing herein shall limit the right of the Executive or the
Executive's beneficiaries to contest the validity or propriety of any such
determination. In addition, to the extent that any action of the Executive
relied upon by the Company to terminate this Agreement pursuant to Section
4(a)(ii) is susceptible of being cured, the Company must provide the Executive
with written notice of its intent to terminate this Agreement (such notice to
identify with specificity the action upon which the Company intends to rely to
terminate this Agreement) and the right of the Company to terminate this
Agreement based upon such action shall be suspended for a period of thirty (30)
days to allow the Executive to cure such action. If the Executive is successful
in curing such action within such thirty (30) day period, such action may not
thereafter be relied upon by the Company as a basis for terminating this
Agreement. As used herein, the term "Disabled" will be deemed to mean the
inability of the Executive, as determined reasonably by the Board, by reason of
any medically determinable physical or mental impairment to engage in the
performance of the material duties of the Executive referenced in Section 2 for
a period which has lasted or can reasonably be expected to last without material
interruption for not less than twelve (12) months.

                  (b)      The Executive shall be entitled to severance benefits
                           as follows:

                           (i)      The Executive will be entitled to benefits
                                    as provided in Section 5 hereof upon any
                                    termination by the Company of this Agreement
                                    for any reason other than (x) for Cause, (y)
                                    as a result of the death of the Executive or
                                    (z) by reason of the Executive becoming
                                    Disabled and the actual receipt by the
                                    Executive of disability benefits in
                                    accordance with Section 4(a)(i) hereof;

                                    Control Severance Payment are hereinafter

                                    arrangement of the Company solely due to the
                                    fact that the Executive is no longer an
                                    officer or employee of the Company, then the

                                    and/or the Executive's dependents and

                                    (B) without limiting the generality of the
                                    foregoing, the remainder of the Term shall
                                    be considered service with the Company for
                                    the purpose of service credits under the

                                    immediately prior to the Termination Date.

                  (b)      If this Agreement is terminated during the Term by
                           the Company pursuant to Section 4(a)(ii) hereof or if
                           this Agreement is terminated during the Term by the
                           Executive for any reason other than pursuant to

                           terminated during the Term (i) by the Company as a
                           result of the death of the Executive or (ii) by the
                           Executive for any reason other than pursuant to
                           Section 4(b) hereof, the Executive will forfeit any
                           right to receive any unpaid Annual Bonus.

                  (c)      Upon written notice given by the Executive to the
                           Company prior to the receipt of any payment pursuant
                           to Section 5(a) hereof, the Executive, at the
                           Executive's sole option, without adjustment to
                           reflect the present value of such amounts as
                           aforesaid, may elect to have all or any of the
                           Severance Payment payable pursuant to Section 5(a)(i)
                           hereof paid to the Executive on a quarterly or
                           monthly basis during the remainder of the Term.

                  (d)      There shall be no right of set-off or counterclaim in
                           respect of any claim, debt or obligation against any
                           payment to or benefit (including Employee Benefits)
                           of the Executive provided for in this Agreement.

                  (e)      Without limiting the rights of the Executive at law
                           or in equity, if the Company fails to make any
                           payment required to be made hereunder on a timely
                           basis, the Company shall pay interest on the amount
                           thereof at an annualized rate of interest equal to
                           the then-applicable Discount Rate (as hereinafter
                           defined) or, if lesser, the highest rate allowed by
                           applicable usury laws. As used herein, the term
                           "Discount Rate" will be deemed to mean the discount
                           rate required to be utilized for purposes of
                           computations under Section 280G of the Internal
                           Revenue Code of 1986, as amended (the "Code"), or any
                           successor provision thereto, or if no such rate is so
                           required to be used, a rate equal to the
                           then-applicable interest rate prescribed by the Code
                           for benefit valuations in connection with
                           non-multiemployer pension plan terminations assuming
                           the immediate commencement of benefit payments.

         6.       No Mitigation Obligation. The parties hereto expressly agree
that the payment of the severance compensation by the Company to the Executive
in accordance with the terms of this Agreement will be liquidated damages, and
that the Executive shall not be required to mitigate the amount of any payment
provided for in this Agreement by seeking other employment or otherwise, nor
shall any profits, income, earnings or other benefits from any source whatsoever
create any mitigation, offset, reduction or any other obligation on the part of
the Executive hereunder or otherwise.

         7.       Legal Fees and Expenses. It is the intent of the Company that
subsequent to the occurrence of a Change in Control, the Executive not be
required to incur the expenses associated with the enforcement of the
Executive's rights under this Agreement by litigation or other legal action
because the cost and expense thereof would substantially detract from the
benefits intended to be extended to the Executive hereunder. Accordingly, if it
should appear to the Executive that the Company has, subsequent to the
occurrence of a Change in Control, failed to comply with any of its obligations
under this Agreement or in the event that the Company or any other person takes
any action, subsequent to the occurrence of a Change in Control, to declare this
Agreement void or unenforceable, or institutes any litigation designed to deny,
or to recover from, the Executive the benefits intended to be provided to the
Executive hereunder, the Company irrevocably authorizes the Executive from time
to time to retain counsel of the Executive's choice, at the expense of the
Company as hereafter provided, to represent the Executive in connection with the
litigation or defense of any litigation or other legal action, whether by or
against the Company or any director, officer, stockholder or other person
affiliated with the Company, in any jurisdiction. Notwithstanding any existing
or prior attorney-client relationship between the Company and such counsel, the
Company irrevocably consents to the Executive's entering into an attorney-client
relationship with such counsel, and in that connection the Company and the
Executive agree that a confidential relationship shall exist between the
Executive and such counsel. The Company shall pay or cause to be paid and shall
be solely responsible for any and all reasonable attorneys' and related fees and
expenses incurred by the Executive as a result of the Company's failure to
perform this Agreement or any provision thereof or as a result of the Company or
any person contesting the validity or enforceability of this Agreement or any
provision thereof as aforesaid.

         8.       Withholding of Taxes. The Company may withhold from any
amounts payable under this Agreement all federal, state, city or other taxes as
shall be required pursuant to any law or government regulation or ruling.

         9.       Successors and Binding Agreement.

                  (a)      The Company shall require any successor (whether
                           direct or indirect, by purchase, merger,
                           consolidation, reorganization or otherwise) to all or
                           substantially all of the business and/or assets of
                           the Company, to expressly assume and agree to perform
                           this Agreement in the same manner and to the same
                           extent the Company would be required to perform if no
                           such succession had taken place. This Agreement shall
                           be binding upon and inure to the benefit of the
                           Company and any successor to the Company, including
                           without limitation any

                           persons acquiring directly or indirectly all or
                           substantially all of the business and/or assets of
                           the Company whether by purchase, merger,
                           consolidation, reorganization or otherwise (and such
                           successor shall thereafter be deemed the "Company"
                           for the purposes of this Agreement). This Agreement
                           shall not otherwise be assignable, transferable or
                           delegable by the Company.

                  (b)      This Agreement shall inure to the benefit of and be
                           enforceable by the Executive's personal or legal
                           representatives, executors, administrators,
                           successors, heirs, distributees and/or legatees.

                  (c)      This Agreement is personal in nature and neither of
                           the parties hereto shall, without the consent of the
                           other, assign, transfer or delegate this Agreement or
                           any rights or obligations hereunder except as
                           expressly provided in Section 9(a) hereof. Without
                           limiting the generality of the foregoing, the
                           Executive's right to receive payments hereunder shall
                           not be assignable, transferable or delegable, whether
                           by pledge, creation of a security interest or
                           otherwise, other than by a transfer by the
                           Executive's will or by the laws of descent and
                           distribution and, in the event of any attempted
                           assignment or transfer contrary to this Section 9(c),
                           the Company shall have no liability to pay any amount
                           so attempted to be assigned, transferred or
                           delegated.

                  (d)      The Company and the Executive recognize that each
                           Party will have no adequate remedy at law for breach
                           by the other of any of the agreements contained
                           herein and, in the event of any such breach, the
                           Company and the Executive hereby agree and consent
                           that the other shall be entitled to a decree of
                           specific performance, mandamus or other appropriate
                           remedy to enforce performance of this Agreement.

         10.      Applicable Law. THIS AGREEMENT WILL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS (EXCLUSIVE OF
CONFLICTS OF LAW PRINCIPLES) AND THE LAWS OF THE UNITED STATES OF AMERICA AND
WILL, TO THE MAXIMUM EXTENT PRACTICABLE, BE DEEMED TO CALL FOR PERFORMANCE IN
DALLAS COUNTY, TEXAS. COURTS WITHIN THE STATE OF TEXAS WILL HAVE JURISDICTION
OVER ANY AND ALL DISPUTES BETWEEN THE PARTIES HERETO, WHETHER IN LAW OR EQUITY,
ARISING OUT OF OR RELATING TO THIS AGREEMENT. THE PARTIES CONSENT

TO AND AGREE TO SUBMIT TO THE JURISDICTION OF SUCH COURTS. VENUE IN ANY SUCH
DISPUTE, WHETHER IN FEDERAL OR STATE COURT, WILL BE LAID IN DALLAS COUNTY,
TEXAS. EACH OF THE PARTIES HEREBY WAIVES, AND AGREES NOT TO ASSERT IN ANY SUCH
DISPUTE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY CLAIM THAT (i)
SUCH PARTY IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF SUCH COURTS, (ii)
SUCH PARTY AND SUCH PARTY'S PROPERTY IS IMMUNE FROM ANY LEGAL PROCESS ISSUED BY
SUCH COURTS OR (iii) ANY LITIGATION COMMENCED IN SUCH COURTS IS BROUGHT IN AN
INCONVENIENT FORUM.

Either party may designate by written notice a new address to which any notice,
demand, request or communication may thereafter be given, served or sent. Each
notice, demand, request or communication that is mailed, delivered or
transmitted in the manner described above will be deemed sufficiently given,
served, sent and received for all purposes at such time as it is delivered to
the addressee with the return receipt, the delivery receipt, the affidavit of
messenger or (with respect to a facsimile transmission) the answer back being
deemed conclusive evidence of such delivery or at such time as delivery is
refused by the addressee upon presentation.

         12.      Gender. Words of any gender used in this Agreement will be
held and construed to include any other gender, and words in the singular number
will be held to include the plural, unless the context otherwise requires.

         13.      Amendment. This Agreement may not be amended or supplemented
except pursuant to a written instrument signed by the party against whom such
amendment or supplement is to be enforced. Nothing contained in this Agreement
will be deemed to create any agency, joint venture, partnership or similar
relationship between the parties to this Agreement. Nothing contained in this
Agreement will be deemed to authorize either party to this Agreement to bind or
obligate the other party.

         14.      Counterparts. This Agreement may be executed in multiple
counterparts, each of which will be deemed to be an original and all of which
will be deemed to be a single agreement. This Agreement will be considered fully
executed when all parties have executed an identical counterpart,
notwithstanding that all signatures may not appear on the same counterpart.

         15.      Severability. If any of the provisions of this Agreement are
determined to be invalid or unenforceable, such invalidity or unenforceability
will not invalidate or render unenforceable the remainder of this Agreement, but
rather the entire Agreement will be construed as if not containing the
particular invalid or unenforceable provision or provisions, and the rights and
obligations of the parties will be construed and enforced accordingly. The
parties acknowledge that if any provision of this Agreement is determined



                                      -14-
<PAGE>   15


to be invalid or unenforceable, it is their desire and intention that such
provision be reformed and construed in such manner that it will, to the maximum
extent practicable, be deemed to be valid and enforceable.

         16.      Third Parties. Except as expressly set forth or referred to in
this Agreement, nothing in this Agreement is intended or will be construed to
confer upon or give to any party other than the parties to this Agreement and
their successors and permitted assigns, if any, any rights or remedies under or
by reason of this Agreement.

         17.      Waiver. No failure or delay in exercising any right hereunder
will operate as a waiver thereof, nor will any single or partial exercise
thereof preclude any other or further exercise or the exercise of any other
right.

         18.      Prior Agreements. This Agreement and the agreements,
instruments and documents contemplated by this Agreement, including, without
limitation, that certain Confidentiality and Noncompetition Agreement, dated
June 6, 1997, by and between the Executive and the Company, represent the
parties' entire agreement with respect to the subject matter of this Agreement
and such other agreements, instruments and documents and supersede and replace
any prior agreement or understanding with respect to that subject matter. This
Agreement may not be amended or supplemented except pursuant to a written
instrument signed by the party against whom such amendment or supplement is to
be enforced. Except as expressly set forth in this Agreement (e.g., Section
19(a), etc.), awards under benefit plans (e.g., stock option awards, restricted
stock grants, phantom stock awards, etc.) are not within the scope of this
Agreement and will not be governed by or affected by this Agreement.

         19.      Certain Additional Payments by the Company.

                  (a)      Anything in this Agreement to the contrary
                           notwithstanding, in the event it shall be determined
                           that any payment or distribution by the Company (or
                           any affiliate, stockholder, or subsidiary thereof or
                           any plan or program of the Company or any affiliate,
                           stockholder, or subsidiary thereof) to the Executive
                           (whether paid or payable or distributed or
                           distributable pursuant to the terms of this Agreement
                           or otherwise, but determined without regard to any
                           additional payments required under this Section 19)
                           (a "Payment") is subject or will cause the Executive
                           to be subject to the excise tax imposed by Section
                           4999 of the Code (or any successor provision) (i.e.,
                           while the Executive is considered a "disqualified
                           individual" as such term is defined in Section 280G
                           of the Code and the regulations promulgated




                                      -15-

                           thereunder), or any interest or penalties are
                           incurred by the Executive with respect to such excise
                           tax (such excise tax, together with any such interest
                           and penalties, are hereinafter collectively referred
                           to as the "Excise Tax"), then the Company shall pay
                           to the Executive an additional payment (a "Gross-Up
                           Payment") in an amount such that after payment by the
                           Executive of all taxes (including any interest or
                           penalties imposed with respect to such taxes),
                           including, without limitation, any income taxes (and
                           any interest and penalties imposed with respect
                           thereto) and Excise Taxes imposed upon the Gross-Up
                           Payment, the Executive retains an amount of the
                           Gross-Up Payment equal to the Excise Tax imposed upon
                           the Payments.

                  (b)      Subject to the provisions of Section 19(c), all
                           determinations required to be made under this Section
                           19, including whether and when a Gross-Up Payment is
                           required and the amount of such Gross-Up Payment and
                           the assumptions to be utilized in arriving at such
                           determination, shall be made by the Company's public
                           accounting firm (the "Accounting Firm") which shall
                           provide detailed supporting calculations both to the
                           Company and the Executive as soon as possible
                           following a request made by the Executive or the
                           Company. In the event that the Accounting Firm is
                           serving as accountant or auditor for the individual,
                           entity or group effecting the Change in Control, the
                           Company shall appoint another nationally recognized
                           public accounting firm to make the determinations
                           required hereunder (which accounting firm shall then
                           be referred to as the Accounting Firm hereunder). All
                           fees and expenses of the Accounting Firm shall be
                           borne solely by the Company. Any Gross-Up Payment, as
                           determined pursuant to this Section 19, shall be paid
                           by the Company to the Executive within five (5) days
                           of the receipt of the Accounting Firm's
                           determination. If the Accounting Firm determines that
                           no Excise Tax is payable by the Executive, it shall
                           furnish the Executive with a written opinion that
                           failure to report the Excise Tax on the Executive's
                           applicable federal income tax return would not result
                           in the imposition of a negligence or similar penalty.
                           Any determination by the Accounting Firm shall be
                           binding upon the Company and the Executive. As a
                           result of the uncertainty in the application of
                           Section 4999 of the Code at the time of the initial
                           determination by the Accounting Firm hereunder, it is
                           possible that Gross-Up Payments which will not have
                           been made by the Company should have been made
                           ("Underpayment"), consistent with the calculations
                           required to



                                      -16-

                           be made hereunder. In the event that the Company
                           exhausts its remedies pursuant to Section 19(c) and
                           the Executive thereafter is required to make a
                           payment of any Excise Tax, the Accounting Firm shall
                           determine the amount of the Underpayment that has
                           occurred and any such Underpayment shall be promptly
                           paid by the Company to or for the benefit of the
                           Executive.

                  (c)      The Executive shall notify the Company in writing of
                           any claim by the Internal Revenue Service that, if
                           successful, would require the payment by the Company
                           of the Gross-Up Payment. Such notification shall be
                           given as soon as practicable but no later than ten
                           (10) business days after the Executive is informed in
                           writing of such claim and shall apprise the Company
                           of the nature of such claim and the date on which
                           such claim is requested to be paid. The Executive
                           shall not pay such claim prior to the expiration of
                           the 30-day period following the date on which the
                           Executive gives such notice to the Company (or such
                           shorter period ending on the date that any payment of
                           taxes with respect to such claim is due). If the
                           Company notifies the Executive in writing prior to
                           the expiration of such period that it desires to
                           contest such claim, the Executive shall:

                           (i)      give the Company any information reasonably
                                    requested by the Company relating to such
                                    claim,

                           (ii)     take such action in connection with
                                    contesting such claim as the Company shall
                                    reasonably request in writing from time to
                                    time, including, without limitation,
                                    accepting legal representation with respect
                                    to such claim by an attorney reasonably
                                    selected by the Company,

                           (iii)    cooperate with the Company in good faith to
                                    effectively contest such claim,

                           (iv)     and permit the Company to participate in any
                                    proceedings relating to such claim;

                           provided, however, that the Company shall bear and
                           pay directly all costs and expenses (including
                           additional interest and penalties) incurred in
                           connection with such contest and shall indemnify and
                           hold the Executive harmless, on a "grossed up,"
                           after-tax basis, for any



                                      -17-

                           Excise Tax or any income or other tax (including
                           interest and penalties with respect thereto) imposed
                           as a result of such representation and payment of
                           costs and expenses. Without limitation on the
                           foregoing provisions of this Section 19(c), the
                           Company shall control all proceedings taken in
                           connection with such contest and, at its sole option,
                           may pursue or forgo any and all administrative
                           appeals, proceedings, hearings and conferences with
                           the taxing authority in respect of such claim and
                           may, at its sole option, either direct the Executive
                           to pay the tax claimed and sue for a refund or
                           contest the claim in any permissible manner, and the
                           Executive agrees to prosecute such contest to a
                           determination before any administrative tribunal, in
                           a court of initial jurisdiction and in one or more
                           appellate courts, as the Company shall determine;
                           provided further, that if the Company directs the
                           Executive to pay such claim and sue for a refund, the
                           Company shall advance the amount of such payment to
                           the Executive on an interest-free basis and shall
                           indemnify and hold the Executive harmless, on a
                           "grossed up," after-tax basis, from any Excise Tax or
                           any income or other tax (including interest or
                           penalties with respect thereto) imposed with respect
                           to such advance or with respect to any imputed income
                           with respect to such advance; and provided further,
                           that any extension of the statute of limitations
                           relating to payment of taxes for the taxable year of
                           the Executive with respect to which such contested
                           amount is claimed to be due is limited solely to such
                           contested amount. Furthermore, the Company's control
                           of the contest shall be limited to issues with
                           respect to which a Gross-Up Payment would be payable
                           hereunder and the Executive shall be entitled to
                           settle or contest, as the case may be, any other
                           issue raised by the Internal Revenue Service or any
                           other taxing authority.

                  (d)      If, after the receipt by the Executive of an amount
                           advanced by the Company pursuant to Section 19(c),
                           the Executive becomes entitled to receive, and
                           receives, any refund with respect to such claim, the
                           Executive shall (subject to the Company's complying
                           with the requirements of Section 19(c)) promptly pay
                           to the Company the amount of such refund (together
                           with any interest paid or credited thereon after
                           taxes applicable thereto). If, after the receipt by
                           the Executive of any amount advanced by the Company
                           pursuant to Section 19(c), a determination is made
                           that the Executive shall not be entitled to any
                           refund with respect to such claim and the Company

                           does not notify the Executive in writing of its
                           intent to contest such denial of refund prior to the
                           expiration of thirty (30) days after such
                           determination, then such advance shall be forgiven
                           and shall not be required to be repaid and the amount
                           of such advance shall offset, to the extent thereof,
                           the amount of Gross-Up Payment required to be paid.

         20.      Forgiveness of Indebtedness; Interest Moratorium. The Company
agrees that the obligations of the Executive to pay principal and/or interest
with respect to that certain Fixed Rate Promissory Note, dated January 28, 1994,
made payable by the Executive to the Company in the original principal amount of
Ninety-Seven Thousand Eight Hundred and 00/100 Dollars ($97,800.00), that
certain Fixed Rate Promissory Note, dated September 22, 1997, made payable by
the Executive to the Company in the original principal amount of Sixteen
Thousand Three Hundred and 00/100 Dollars ($16,300.00) and that certain Fixed
Rate Promissory Note, dated January 14, 1998, made payable by the Executive to
the Company in the original principal amount of Forty-Eight Thousand Nine
Hundred and 00/100 Dollars ($48,900.00) as such notes have been previously or
may be hereafter renewed, extended or modified (hereinafter collectively
referred to as the "Notes") are suspended (although interest will continue to
accrue) until the close of business on January 3, 2001 and; provided the
Executive has not terminated this Agreement during the Term other than pursuant
to Section 4(b) and the Company has not terminated this Agreement pursuant to
Section 4(a)(ii), the such obligations will terminate on the close of business
on January 3, 2001. At such time, if the Company has not previously terminated
this Agreement pursuant to Section 4(a)(ii), the Company will mark such Notes
"paid in full" and will deliver such Notes to the Executive.

         21.      No Retroactive Recovery of Compensation. The Company hereby
waives any right to seek recovery of any payment or other benefit paid or
provided to the Executive pursuant to this Agreement subsequent to the payment
or delivery thereof.

         22.      Assistance with Transition. In the event the Executive elects
not to renew this Agreement, the Executive agrees to use reasonable efforts to
assist the Company in retaining a successor for the Executive and in exchange
for such assistance, the Board may, in its sole discretion, elect to accelerate
the vesting of any option, restricted stock, phantom stock, stock appreciation
or similar award made to the Executive. The Company acknowledges and agrees that
the failure of the Executive to comply with the provisions of this Section 22
will not give rise to any remedy on behalf of the Company (including, without
limitation, any right to terminate this Agreement or any other agreement between
the Company and the Executive or any right to equitable relief) or subject the
Executive to any liability (including, without limitation, damages, whether
sought in an action at law or in equity and whether or not sought in an action
in contract, in tort or otherwise).
