Exhibit 10.36 EMPLOYMENT AGREEMENT This Employment Agreement (the "Agreement") is entered into by and between Versicor Inc., a Delaware corporation (the "Company"), and Timothy J. Henkel, M.D., Ph.D. (the "Executive"), as of the 18th day of December,...

Exhibit 10.36

EMPLOYMENT AGREEMENT

This Employment Agreement (the "Agreement") is entered into by and between
Versicor Inc., a Delaware corporation (the "Company"), and ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇,
M.D., Ph.D. (the "Executive"), as of the 18th day of December, 2000.

WHEREAS, the Board of Directors of the Company (the "Board") has
determined that it is in the best interests of the Company and its stockholders
to assure that the Company will have the service of the Executive, and the Board
therefore desires to provide the Executive with compensation and benefits
arrangements that satisfy the expectations of the Executive and that are
competitive with those of other corporations; and

WHEREAS, the Board also desires to assure that the Executive's services
will be available notwithstanding the possibility, threat or occurrence of a
Change of Control (as defined below) of the Company, and the Board believes it
is imperative to diminish the inevitable distraction of the Executive by virtue
of the personal uncertainties and risks created by a pending or threatened
Change of Control and to encourage the Executive's full attention and dedication
to the Company in the event of any threatened or pending Change of Control.

NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto, intending to be
legally bound, do hereby agree as follows:

I. EMPLOYMENT PERIOD.

The Company hereby agrees to employ Executive, and the Executive hereby
accept such employment with the Company, subject to the terms and conditions of
this Agreement, for the period commencing on December 18, 2000 ("Effective
Date") and ending on the third anniversary of such date (the "Employment
Period"); provided, however, that commencing on the date one year after the
Effective Date, and on each annual anniversary of the Effective Date (such date
and each annual anniversary thereof shall be hereinafter referred to as the
"Renewal Date"), unless previously terminated, the Employment Period shall be
automatically extended so as to terminate three years from such Renewal Date,
unless at least 60 days prior to the Renewal Date the Company shall give notice
to the Executive that the Employment Period shall not be so extended.

II. DUTIES.

A. During the Employment Period, the Executive shall serve as the Chief
Medical Officer and Executive Vice President of the Company, and shall have such
other duties and responsibilities, reasonably consistent with his position with
the Company, as the Board of Directors of the Company shall determine from time
to time. A description of the duties and responsibilities of the Executive is
attached to this Agreement as Exhibit A.

B. During the Employment Period, the Executive agrees to devote
substantially all of his time, energy and ability to the business of the
Company. Nothing herein shall prevent the Executive, upon approval of the Board
of Directors of the Company, from

serving as a director or trustee of other corporations or businesses that are
not in competition with the business of the Company or in competition with any
present or future affiliate of the Company, provided such service does not
materially interfere with the Executive's duties hereunder.

III. COMPENSATION.

A. BASE SALARY. The Company will pay to the Executive a base salary at
the rate of $295,000 per year. Such salary shall be earned monthly and shall be
payable in periodic installments no less frequently than monthly in accordance
with the Company's customary practices. Amounts payable shall be reduced by
standard withholding and other authorized deductions. The Company will review
the Executive's salary at least annually. The Company may in its discretion
increase the Executive's salary but it may not reduce it during the term of this
Agreement. Any increase in the Executive's salary shall not serve to limit or
reduce any other obligation to the Executive under this Agreement.

B. ANNUAL BONUS, INCENTIVE, SAVINGS AND RETIREMENT PLANS. The Executive
shall be entitled to participate in all annual bonus, incentive, stock
incentive, savings and retirement plans, defined contribution plans, practices,
policies and programs applicable generally to other executives of the Company.

The Executive's bonus opportunity for 2001 is $60,000, subject to the
completion or performance of each of the objectives as set forth in a letter
from the Company to the Executive dated December 7, 2000 (the "Offer Letter").

At the first meeting of the Board on or after the Effective Date, the
Company's management shall recommend to the Board that it approve a stock option
grant to the Executive covering 400,000 shares of the Company's common stock
(the "Common Stock") (such number of shares to be adjusted to reflect stock
splits, reverse stock splits, stock dividends, and similar changes in
capitalization of the Company after the date hereof). To the maximum extent
possible, such option shall be an incentive stock option within the meaning of
Section 422 of the Internal Revenue Code of 1986, as amended.

The per share exercise price of the option granted pursuant to the
foregoing paragraph shall equal the closing price of a share of Common Stock on
the NASDAQ on the date the Board approves the option. Such option shall be
granted under the Company's 1997 Equity Incentive Plan (the "Plan"), and (A)
shall be granted subject to the terms of the Plan and (B) shall be evidenced by
and granted subject to the terms of a stock option agreement in substantially
the form delivered to the Executive with this Agreement and attached to this
Agreement as Exhibit B. The Executive acknowledges having received a copy of the
Plan and such form of stock option agreement. The "Date of Grant" of such option
shall be the date the Board approves the grant. The "Vesting Commencement Date"
of such option shall be the Effective Date. The "Expiration Date" of such option
shall be the day before the tenth (10th) anniversary of the Date of Grant.
Executive's acceptance of this Agreement and the obligations and duties
hereunder shall be conditioned upon the Board's approval and grant of such stock
option on or before December 31, 2000.

Notwithstanding anything in the Plan or in the form of stock option
agreement to the contrary, Executive shall be permitted to transfer all or a
portion of such option; provided that (A) the Executive notifies the Company in
writing of the contemplated transfer, (B) the transfer is a gift to a "family
member" (as such term is defined in the General Instructions to a Form S-8
Registration Statement under the Securities Act of 1933, as amended), (C) the
transfer, in the reasonable opinion of the Company and/or its legal counsel,
will not frustrate the Company's ability to rely on a Form S-8 Registration
Statement to issue or deliver the securities underlying the option upon an
exercise thereof, and (D) the Executive and his proposed transferee provide such
documents, agreements and/or assurances to the Company as the Company may
reasonably require to assure compliance with all applicable tax laws and
withholding requirements.

C. WELFARE BENEFIT PLANS. The Executive and/or his family, as the case
may be, shall be eligible for participation in and shall receive all benefits
under welfare benefit plans, practices, policies and programs provided by the
Company (including, without limitation, medical, prescription, dental,
disability, salary continuance, executive life, group life, accidental death and
travel accident insurance plans and programs) to the extent such plan,
practices, and programs are applicable generally to executives of the Company. A
summary of the benefits currently available to executives is attached to this
Agreement as Exhibit C.

D. EXPENSES. The Executive shall be entitled to receive prompt
reimbursement for all reasonable employment expenses incurred by him in
accordance with the policies, practices and procedures as in effect generally
with respect to other executives of the Company.

E. FRINGE BENEFITS. The Executive shall be entitled to fringe benefits
in accordance with the plans, practices, programs and policies as in effect
generally with respect to other executives of the Company.

F. VACATION. The Executive shall be entitled to paid vacation time in
accordance with the plans, policies, programs and practices as in effect with
respect to other executives of the Company; provided that the Executive shall be
entitled to no less than three (3) weeks paid vacation per year, no less than
five (5) paid personal days off per year in addition to such vacation, and no
less than five (5) paid days off per year for continuing education in addition
to such vacation and personal days, all t be taken in accordance with the
Company's usual policies and practices.

G. PLAN AMENDMENTS. The Company reserves the right to modify, suspend
or discontinue any and all of its executive plans, practices, policies and
programs at any time without recourse by the Executive so long as such action is
taken generally with respect to other similarly situated executives and does not
single out the Executive.

H. SIGN-ON BONUS. The Company shall pay to Executive the sign-on bonus
contemplated by the Offer Letter.

IV. TERMINATION.

A. DEATH OR DISABILITY. The Executive's employment shall terminate
automatically upon the Executive's death. If the Company determines in good
faith that a Disability of the Executive has occurred (as Disability is defined
below), it may give to the Executive written notice in accordance with Section
XIV of its intention to terminate the Executive's employment. In such event, the
Executive's employment with the Company shall terminate effective on the 30th
day after receipt of such notice by the Executive (the "Disability Effective
Date"), provided that, within the 30 days after such receipt, the Executive
shall not have returned to full-time performance of his duties. For purposes of
this Agreement, "Disability" shall mean the absence of the Executive from his
duties with the Company on a full-time basis (1) for a period of three
consecutive months as a result of incapacity due to mental or physical illness
that is determined to be total and permanent by a physician selected by the
Company or its insurers and acceptable to the Executive or his legal
representative (such agreement as to acceptability not to be withheld
unreasonably) or (2) for shorter periods aggregating 180 or more business days
in any twelve (12) month period. "Incapacity" as used herein shall be limited
only to such Disability which substantially prevents the Company from availing
itself of the services of the Executive or substantially impairs the Executive's
ability to perform services to the standard reasonably expected by the Company
for the Executive's office.

B. CAUSE. The Company also may at any time, before or after a Change in
Control, terminate the Executive's employment for "Cause." For purposes of this
Agreement, "Cause" shall mean that the Company, acting in good faith based upon
the information then known to the Company, determines that the Executive has:
(1) repeatedly failed to perform in a material respect his obligations under the
Agreement without proper reason and has not cured such failure in a reasonable
time after receiving notice from the Company (but failure to meet any of the
performance goals set forth in the Offer Letter shall not, in and of itself, be
deemed a failure of Executive to have performed his obligations under this
Agreement), (2) willfully engaged in illegal conduct or gross misconduct that is
materially injurious to the Company, or (3) willfully breached the provisions of
Section VI (Confidential Information) of this Agreement. Notwithstanding the
foregoing, the Company may not terminate the Executive's employment for "Cause"
(1) if such termination (or notice of impending termination to the Executive)
occurs more than ninety (90) days after the Company's first actual knowledge of
the underlying act, failure to act, or conduct that constituted the particular
grounds for the termination, and (2) unless the Executive is given an
opportunity to address the Board with respect to such termination prior to the
time of the termination. Section VI will continue in effect in the event that
the Executive's employment is terminated for Cause.

For purposes of this provision, no act or failure to act, on the part of
the Executive, shall be considered "willful" unless it is done, or omitted to be
done, by the Executive in bad faith or without reasonable belief that the
Executive's action or omission was in the best interests of the Company. Any
act, or failure to act, based upon authority given pursuant to a resolution duly
adopted by the Board or upon the instructions of the Chief Executive Officer or
a senior officer of the Company or based upon the advice of counsel for the
Company shall be conclusively presumed to be done, or omitted to be done, by the
Executive in good faith and in the best interests of the Company. No termination
of the Executive for Cause will be effective unless adopted pursuant to a
resolution duly adopted by the affirmative vote of not less than a

majority of the entire membership of the Board at a meeting of the Board called
and held for such purpose, and communicated to the Executive by written notice
that explains the basis on which Cause has been found.

C. OBLIGATIONS OF THE COMPANY UPON TERMINATION.

1. CAUSE, ETC. If the Executive's employment is terminated by the
Company for Cause pursuant to Section IV-B, or if the Executive's employment
is voluntarily terminated by the Executive (subject to Section V-A), or if
the Executive's employment is terminated by reason of the Executive's Death
or Disability, this Agreement shall terminate without further obligations to
the Executive other than for (a) payment of the sum of the Executive's annual
base salary through the date of termination and any accrued vacation pay to
the extent not theretofore paid, which shall be paid to the Executive or his
estate or beneficiary, as applicable, in a lump sum in cash within 30 days of
the Date of Termination; (b) payment of any compensation previously earned
and deferred by the Executive (together with any accrued interest or earnings
thereon), which shall be paid to the Executive or his estate or beneficiary
at the times provided in, and pursuant to terms of, the plan or agreement
under which such compensation was deferred; (c) and reimbursement to
Executive of any other amounts for expenses then due to him under this
Agreement; and (d) payment to the Executive or his estate or beneficiary, as
applicable, any amounts due pursuant to the terms of any applicable welfare
benefit plans. The payments described in clauses (a), (b) and (c) shall
hereinafter be referred to as the "Accrued Obligations." If it is
subsequently determined that the Company did not have the right to terminate
the Executive for Cause under Section IV-B, then the Company's decision to
terminate shall be deemed to have been made under Section IV-C-2 and the
amounts payable thereunder shall be the only amounts the Executive may
receive for his termination.

2. OTHER. If the Company terminates the Executive's employment under
this Agreement other than pursuant to Sections IV-A or IV-B, or the Executive
terminates his employment under this Agreement as a result of a change in the
Executive's office location to a point more than 35 miles from the
Executive's office, the Company shall pay to the Executive by cashier's check
immediately upon the Executive's termination of employment with the Company
an amount equal to two times the sum of (1) the amount of the annual base
salary then being paid or required to be paid to the Executive by the Company
under this Agreement and (2) the amount of the highest bonus (or bonuses)
paid to the Executive by the Company for any calendar year ending prior to
the year in which the termination of the Executive's employment occurs. This
payment shall be in addition to the timely payment of the Accrued
Obligations. The Executive shall have no duty to mitigate damages and none of
the payments provided in this Section IV-C-2 shall be reduced by any amounts
earned or received by Executive from a third party at any time.

3. EXCLUSIVE REMEDY. The Executive agrees that the payments
contemplated by this Agreement shall constitute the exclusive and sole remedy
for any termination of his employment and the Executive covenants not to
assert or pursue any other remedies, at law or in equity, with respect to any
termination of employment.

D. NOTICE OF TERMINATION. Any termination by the Company for Cause, or
by the Executive for Good Reason, shall be communicated by Notice of Termination
to the other

party hereto given in accordance with Section XIV of this Agreement. For
purposes of this Agreement, a "Notice of Termination" means a written notice
which (1) indicates the specific termination provision in this Agreement relied
upon, (2) to the extent applicable, sets forth in reasonable detail the facts
and circumstances claimed to provide a basis for termination of the Executive's
employment under the provision so indicated and (3) if the Date of Termination
(as defined below) is other than the date of receipt of such notice, specifies
the termination date (which date shall be not more than thirty days after the
giving of such notice). The failure by the Executive or the Company to set forth
in the Notice of Termination any fact or circumstance which contributes to a
showing of Good Reason or Cause shall not waive any right of the Executive or
the Company, respectively, hereunder or preclude the Executive or the Company,
respectively, from asserting such fact or circumstance in enforcing the
Executive's or the Company's rights hereunder.

E. DATE OF TERMINATION. "Date of Termination" means (1) if the
Executive's employment is terminated by the Company for Cause, or by the
Executive for Good Reason, the date of receipt of the Notice of Termination or
any later date specified therein, as the case may be, (2) if the Executive's
employment is terminated by the Company other than for Cause or Disability, the
Date of Termination shall be the date on which the Company notifies the
Executive of such termination and (3) if the Executive's employment is
terminated by reason of Death or Disability, the Date of Termination shall be
the date of death of the Executive or the Disability Effective Date, as the case
may be.

V. CHANGE IN CONTROL.

A. CHANGE OF CONTROL PAYMENTS. Notwithstanding anything to the contrary
in this Agreement, if a Change in Control (as defined below) of the Company
occurs during the term of this Agreement, and if within two years following such
Change in Control either the Company terminates the Executive's employment
without Cause, or if the Executive terminates his employment for Good Reason (as
defined below), the Company shall pay to the Executive by cashier's check
immediately upon the Executive's termination of employment with the Company an
amount equal to two times the sum of (1) the amount of the annual base salary
then being paid or required to be paid to the Executive by the Company under
this Agreement and (2) the amount of the highest bonus (or bonuses) paid to the
Executive by the Company for any calendar year ending prior to the year in which
the Change in Control occurs. This payment shall be in lieu of the payment
otherwise payable under Section IV-C-2, but shall be in addition to the timely
payment of the Accrued Obligations. In addition, the Company shall continue to
provide all benefits under the welfare benefit plans as set forth in Section
III-C until the earlier of (1) the Executive's receipt of benefits substantially
similar in scope and nature from another employer or (2) three years after the
most recent Renewal Date. The Executive shall have no duty to mitigate damages
and none of the payments provided in this Section V-A shall be reduced by any
amounts earned or received by the Executive from a third party at any time.
Notwithstanding anything to the contrary in this Section V, if, in connection
with a Change in Control transaction, the Executive voluntarily enters a new
written employment agreement with the Company or its successor, the Executive
may no longer rely upon the provisions of this Section V.

B. CERTAIN ADDITIONAL PAYMENTS.

1. Notwithstanding anything in this Agreement to the contrary and
except as set forth below, in the event it shall be determined that any
payment or distribution by the Company or its affiliates to or for the
benefit of 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 V-B) (a "Payment") would be subject to the excise tax imposed by
Section 4999 of the Internal Revenue Code 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 Executive shall be entitled to
receive 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 Tax 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. Notwithstanding the foregoing provisions of this Section
V-B-1, if it shall be determined that the Executive is entitled to a Gross-Up
Payment, but that the Payments do not exceed 110% of the greatest amount (the
"Reduced Amount") that could be paid to the Executive such that the receipt
of Payments would not give rise to any Excise Tax, then no Gross-Up Payment
shall be made to the Executive and the Payments, in the aggregate, shall be
reduced to the Reduced Amount.

2. Subject to the provisions of Section V-B-3, all determinations
required to be made under this Section V-B, 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 PricewaterhouseCoopers LLP or such other certified public accounting firm
as may be designated by the Executive (the "Accounting Firm") which shall
provide detailed supporting calculations both to the Company and the
Executive within 15 business days of the receipt of notice from the Executive
that there has been a Payment, or such earlier time as is requested by the
Company. In the event that the Accounting Firm is serving as accountant or
auditor for the individual, entity or group effecting the Change of Control,
the Executive shall appoint another nationally recognized 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 V-B, shall be paid by the
Company to the Executive within five days of the receipt of the Accounting
Firm's determination. 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 that will not have been made by the Company should have been made
("Underpayment"), consistent with the calculations required to be made
hereunder. In the event that the Company exhausts its remedies pursuant to
Section V-B-3 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.

3. 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 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 it 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:

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

(b) 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,

(d) 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 an after-tax basis, for any Excise Tax or income 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 V-B-3, 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
▇▇▇ 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, however,
that if the Company directs the Executive to pay such claim and ▇▇▇ 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 an after-tax basis, from any Excise Tax or income 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 further provided 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.

4. If, after the receipt by the Executive of an amount advanced
by the Company pursuant to Section V-B-3, the Executive becomes entitled to
receive any refund with respect to such claim, the Executive shall (subject to
the Company's complying with the requirements of Section V-B-3) 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 an amount advanced by the Company pursuant to Section V-B-3, 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 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.

C. DEFINITIONS. For purposes of this Agreement and Section V
hereof:

1. A "Change in Control" of the Company means any of the
following:

(a) Approval by the stockholders of the Company of the dissolution
or liquidation of the Company;

(b) Approval by the stockholders of the Company of an agreement to
merge or consolidate, or otherwise reorganize, with or into one or more entities
that are not subsidiaries or other affiliates, as a result of which less than
50% of the outstanding voting securities of the surviving or resulting entity
immediately after the reorganization are, or will be, owned, directly or
indirectly, by stockholders of the Company immediately before such
reorganization (assuming for purposes of such determination that there is no
change in the record ownership of the Company's securities from the record date
for such approval until such reorganization and that such record owners hold no
securities of the other parties to such reorganization, but including in such
determination any securities of the other parties to such reorganization held by
affiliates of the Company);

(c) Approval by the stockholders of the Company of the sale of all
or substantially all of the Company's business and/or assets to a person or
entity which is not a subsidiary or other affiliate; or

(d) Any "person" (as such term is used in Sections 13(d) and 14(d)
of the Securities Exchange Act of 1934 (the "Exchange Act") but excluding any
person described in and satisfying the conditions of Rule 13d-1(b)(1)
thereunder), becomes the "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act), directly or indirectly, of securities of the Company representing
more than 40% of the combined voting power of the Company's then outstanding
securities entitled to then vote generally in the election of directors of the
Company; or

(e) During any period not longer than two consecutive years,
individuals who at the beginning of such period constituted the Board of
Directors of the Company cease to constitute at least a majority thereof, unless
the election, or the nomination for election by the Corporation's stockholders,
of each new Board member was approved by a vote of at least three-

fourths of the Board members then still in office who were Board members at the
beginning of such period (including for these purposes, new members whose
election or nomination was so approved).

2. "Good Reason" shall mean (with or without regard to whether a
Change in Control has occurred), without obtaining the Executive's prior written
consent thereto, (a) an adverse and significant change in the Executive's
position, duties, responsibilities, or status with the Company, (b) a change in
the Executive's office location to a point more than 35 miles from the
Executive's office; (c) the taking of any action by the Company to eliminate
benefit plans without providing substitutes which, in overall, provide a
substantially similar aggregate value of benefits, to reduce benefits thereunder
or to substantially diminish the aggregate value of incentive awards or other
fringe benefits, (d) any reduction in the Executive's base salary, (e) any
purported termination by the Company of the Executive's employment other than as
expressly permitted by this Agreement, or (f) any breach of this Agreement by
the Company. "Good Reason" shall also mean and include, without limitation, any
termination by the Executive of his employment with the Company at any time
within one year following a Change in Control, whether with or without reason.

VI. CONFIDENTIAL INFORMATION.

A. The Executive shall hold in a fiduciary capacity for the benefit of
the Company all secret or confidential information, knowledge or data relating
to the Company or any of its affiliated companies, and their respective
businesses, which shall have been obtained by the Executive during his
employment by the Company and which shall not be or become public knowledge
(other than by acts by the Executive or his representatives in violation of this
Agreement). After termination of the Executive's employment with the Company, he
shall not, without the prior written consent of the Company, or as may otherwise
be required by law or legal process, communicate or divulge any such
information, knowledge or data to anyone other than the Company and those
designated by it; PROVIDED, however, that the Executive will not be so bound if
following a Change in Control the Executive is terminated without Cause or if
the Executive terminates his employment for Good Reason.

B. The Executive agrees that all lists, materials, books, files,
reports, correspondence, records, and other documents ("Company material") used,
prepared, or made available to the Executive, shall be and shall remain the
property of the Company. Upon the termination of employment or the expiration of
this Agreement, all Company materials shall be returned immediately to the
Company, and the Executive shall not make or retain any copies thereof.

VII. SUCCESSORS.

A. This Agreement is personal to the Executive and shall not, without
the prior written consent of the Company, be assignable by the Executive
otherwise than by will or the laws of descent and distribution. This Agreement
shall inure to the benefit of and be enforceable by the Executive's legal
representatives.

B. This Agreement shall inure to the benefit of and be binding upon the
Company and its successors and assigns and any such successor or assignee shall
be deemed substituted for the Company under the terms of this Agreement for all
purposes. As used herein, "successor" and "assignee" shall include any person,
firm, corporation or other business entity which at any time, whether by
purchase, merger or otherwise, directly or indirectly acquires the stock of the
Company or succeeds to all or substantially all of the assets or business of the
Company, or to which the Company assigns this Agreement by operation of law or
otherwise.

VIII. WAIVER.

No waiver of any breach of any term or provision of this Agreement shall
be construed to be, nor shall be, a waiver of any other breach of this
Agreement. No waiver shall be binding unless in writing and signed by the party
waiving the breach.

IX. MODIFICATION.

This Agreement may not be amended or modified other than by a written
agreement executed by the Executive and the Company.

X. SAVINGS CLAUSES.

A. If any provision of this Agreement or the application thereof is
held invalid, the invalidity shall not affect other provisions or applications
of the Agreement which can be given effect without the invalid provisions or
applications and to this end the provisions of this Agreement are declared to be
severable.

B. If any provision of this Agreement would, in the written opinion of
the Company's independent accountants, prevent or substantially interfere with
the Company's ability to receive pooling treatment in any business combination,
the offending provision will be deemed severed from this Agreement and the other
provisions of this Agreement shall not be affected.

XI. COMPLETE AGREEMENT.

This instrument (together with the performance criteria set forth in, and
