dated January 19, 1995.

         WHEREAS, on or about January 25, 1995, Bank One, Texas and Bank One,

whereby Bank One, Youngstown participated with Bank One, Texas with respect to
the Credit.

         WHEREAS, on or about June 16, 1997, Bank One, Texas, Bank One,

<PAGE>   2

         1. MODIFICATION OF OTHER DOCUMENTS. The terms and conditions set forth
in the Credit Agreement, Promissory Note and prior Loan Modification Agreements
shall remain in full force and effect except as expressly modified herein.

         2. LINE OF CREDIT. By entering into this Agreement, Bank One and
Borrowers hereby agree that the amount of the revolving working capital line of
credit, as defined in the Credit Agreement, shall be modified to the principal
sum of Four Million and 00/100 Dollars ($4,000,000.00).

         3. INTEREST RATE. Upon execution of this Agreement, the interest rate
set forth in the Promissory Note and/or Credit Agreement shall be modified to
the "LIBOR Rate", as defined herein, plus One Hundred Fifty (150) basis points.
"LIBOR Rate" shall mean a per annum rate of interest equal to the LIBOR Rate for
an interest period (the "Interest Period") of one month or three months, as
designated by the Borrower. Borrower shall elect at the time of each advance
under the Credit, with respect to such advance, for interest to accrue at a
LIBOR Rate for a designated LIBOR Interest Period. For purposes of this Note,
the "LIBOR Rate" means, with respect to an advance for the relevant Interest
Period, the applicable British Bankers' Association Interest Settlement Rate for
deposits in U.S. dollars appearing on Reuters Screen FRBD as of 11:00 a.m.
(London time) two Business Days prior to the first day of such Interest Period,
and having a maturity equal to such Interest Period, provided that, (i) if
Reuters Screen FRBD is not available to the Lender for any reason, the
applicable LIBOR Rate for the relevant Interest Period shall instead be the
applicable British Bankers' Association Interest Settlement Rate for deposits in
U.S. dollars as reported by any other generally recognized financial information
service as of 11:00 a.m. (London time) two Business Days prior to the first day
of such Interest Period, and having a maturity equal to such Interest Period,
and (ii) if no such British Bankers' Association Interest Settlement Rate is
available to the Lender, the applicable LIBOR Rate for the relevant Interest
Period shall instead be the rate determined by the Lender to be the rate at
which BANK ONE CORPORATION or one of its affiliate banks offers to place
deposits in U.S. dollars with first-class banks in the London interbank market
at approximately 11:00 a.m. (London time)

                                       2

<PAGE>   3

two Business Days prior to the first day of such Interest Period, in the
approximate amount of the relevant advance and having a maturity equal to such
Interest Period. When the interest rate is based on a LIBOR Rate, the rate shall
be in effect for a period of the number of months as offered in the rate option
description of the "Interest Period", provided that if any Interest Period is
scheduled to end on a date for which there is no numerical equivalent to the
date on which the Interest Period commenced, then it shall end instead on the
last day of such calendar month, beginning on a borrowing date, conversion date
or expiration date of the then current Interest Period.

         4. COMMITMENT TERMINATION DATE. The Promissory Note and Credit
Agreement are hereby modified to provide that the outstanding balance of
principal, interest and other charges due pursuant to the Promissory Note,
Credit Agreement and prior Loan Modification Agreements shall be due and payable
in full on or before May 31, 2002. All other payments of interest or other
amounts provided for in the Promissory Note and/or Credit Agreement shall

and/or Credit Agreement, except for as otherwise modified herein.

parties agree that the remaining provisions shall be deemed to be in full force
and effect as if they had been executed by all parties subsequent to the
expungement of the invalid provision. This clause shall also be applicable to
any documents executed in connection herewith.

                          GENENCOR INTERNATIONAL, INC.

                 STOCK OPTION AND STOCK APPRECIATION RIGHT PLAN

          1. PURPOSE. The GENENCOR INTERNATIONAL, INC. STOCK OPTION AND STOCK
APPRECIATION RIGHT PLAN (hereinafter referred to as the "Plan") is designed to
retain, attract and motivate the best available personnel and to furnish
additional incentive to employees, outside directors, consultants and advisors
of Genencor International, Inc. or its subsidiaries, (hereinafter referred to as
the "Company"), as defined in Section 424 of the Internal Revenue Code of 1986,
as amended (hereinafter referred to as the "Internal Revenue Code") upon whose
efforts the successful conduct of the business of the Company largely depends,
by encouraging such individuals to acquire a proprietary interest in the Company
or to increase the same. This purpose will be effected through the granting of
options to purchase the Common Stock, one cent ($.01) par value per share, of
the Company (the "Shares") which options will be identified by the Board of
Directors of the Company (hereinafter referred to as the "Board") either as
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code or as nonstatutory stock options. This purpose also will be
effected through the granting of stock appreciation rights (hereinafter referred
to as "SARs"), as hereinafter defined, by the Board, or by such officer or
officers of the Company to whom the Board may delegate the authority to issue
SARs.

          2. ELIGIBILITY. The persons eligible to receive options and SARs under
this Plan shall be such employees, outside directors, consultants or advisors of
the Company as the Board shall select from time to time, provided that: (a)
incentive stock options shall be granted only to employees, and (b) no
individual who is a member of an investment firm which is a party to a public or
private offering of any securities of the Company shall be eligible to receive
options or SARs under this Plan. Employees eligible for grants under this Plan
include only those persons designated as employees by the Company, and do not
include: (a) any person whose relationship to the Company is that of an
independent contractor under common law; or (b) any person engaged by the
Company as an "independent contractor" even if it shall later be determined by a
governmental agency for some other purpose that such person was an "employee."
The preceding sentence shall not limit or restrict the ability of the Company to
grant options and SARs to outside directors, consultants and advisors when the
grant is specifically and expressly made to such persons in that capacity.
Persons receiving options or SARs under this Plan are hereinafter referred to as
"Participants."

          3. STOCK SUBJECT TO OPTIONS AND SARS. Subject to the provisions of
Section 12 hereof, options may be granted under the Plan to purchase, and SARs
may be granted with respect to, in the aggregate, not more than nine million
(9,000,000) Shares. In addition, subject to the provisions of Section 12 hereof,
options and SARs granted to any Participant shall not cover more than the
maximum number of Shares then available for grant. The Shares may, in the
discretion of the Board, consist either in whole or in part of authorized but
unissued Shares or Shares held in the treasury of the Company, and the Shares
may, in the discretion of the Board, become subject to incentive stock options,
nonstatutory stock options, or SARs. Any Shares subject to an option or SAR
which for any reason expires or is terminated unexercised or without

                                       1
<PAGE>   2

maturing as to such Shares shall continue to be available for the grant of
options or SARs under the Plan.

          4. ANNUAL LIMITATION FOR INCENTIVE STOCK OPTIONS. The aggregate fair
market value (determined as of the time the option is granted) of the Shares
with respect to which incentive stock options are exercisable for the first time
by a Participant during any calendar year (under all incentive stock option
plans of the Company, any parent and any subsidiaries) shall not exceed one
hundred thousand dollars ($100,000); the options or portions thereof which
exceed such limit (according to the order in which they were granted) shall be
treated as nonstatutory stock options.

          5. TERMS AND CONDITIONS OF OPTIONS. Each option granted by the Board
pursuant to this Plan shall be evidenced by a stock option agreement in such
form or forms as the Board may from time to time prescribe (which agreements
need not be identical) containing provisions consistent with the Plan, including
a waiting period following the grant of the option during which all or any part
of the option may not be exercised. Any right of the Company to terminate the
Participant's employment or status as an outside director, consultant or advisor
at any time, with or without cause, shall in no way be restricted by the
existence of this Plan, any option granted hereunder, or any stock option
agreement relating thereto. Options shall in all cases further be subject to the
following terms and conditions:

                    a. TYPE OF OPTION AND PRICE. Each option grant shall state
the number of Shares subject to the option, whether the option is intended to be
an incentive stock option or a nonstatutory stock option and the option price.
The option price of any incentive stock option shall equal or exceed the fair
market value of the Shares with respect to which the incentive stock option is
granted at the time of the granting of the option. The option exercise price of
any nonstatutory stock option shall equal or exceed eighty-five percent (85%) of
the fair market value of the Shares with respect to which the nonstatutory stock
option is granted at the time of the granting of the option. However, if an
incentive or nonstatutory stock option is granted to any person who is deemed to
own stock possessing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or any parent or subsidiary
(hereinafter referred to as a "Ten Percent Stockholder"), the option price shall
not be less than one hundred ten percent (110%) of the fair market value of the
Shares with respect to which the option is granted at the time of the granting
of the option to the Ten Percent Stockholder. For this and other purposes under
the Plan, the fair market value of the Shares shall equal: (a) the public
trading price, if the Shares are publicly traded, or (b) the value set by the
Board in good faith and from time to time, as the Board deems reasonable in its
sole discretion (without regard to any restrictions other than a restriction
which, by its terms, will never lapse) based upon a reasonable method of
valuation adopted (and reasonably adjusted or replaced from time to time, as the
Board deems reasonable) in accordance with Section 422(c)(1) of the Internal
Revenue Code. The Board will use its good faith efforts to determine the fair
market value of the Shares, but neither the Board nor the Company will be
responsible for the payment of any tax imposed upon the Participants.

                    b. TERM. The term of each option shall be determined by the
Board, but in no event shall an option be exercisable either in whole or in part
after the expiration of ten (10) years from the date on which it is granted.
Notwithstanding the foregoing, an incentive stock

                                       2
<PAGE>   3

option granted to a Ten Percent Stockholder shall not be exercisable either in
whole or in part after the expiration of five (5) years from the date on which
it is granted. The Board and a Participant may at any time by mutual agreement
terminate any option granted to such Participant under the Plan.

                    c. EXERCISE. Each option shall provide a vesting schedule
for its exercise as determined by the Board and as set forth in the option
agreement for such option; provided, however, that options granted prior to an
initial public offering of the Shares and subject to applicable law, shall
provide for vesting of the total number of options at a rate thirty-three and
1/3 percent (33-1/3%) per year over three (3) years from the date the option was
granted, subject to reasonable conditions such as continued employment.
Notwithstanding the foregoing, the Board may, in its sole discretion, accelerate
the exercise period of any option based upon an individual optionee's
performance or other factors. Each option, or any installment thereof, shall be
exercised, whether in whole or in part, by giving written notice to the Company
at its principal office, specifying the number of Shares purchased and the
purchase price being paid, and accompanied by the payment of the purchase price.
A Participant may pay for the Shares subject to the option with cash, a
certified check or a bank cashier's check payable to the order of the Company.
Alternatively, with the consent of the Board and in the sole discretion of the
Board, the Participant may be permitted to pay for the Shares, in whole or in
part, by the delivery of Shares already owned by the Participant, provided such
shares have been held by the Participant for at least six (6) months after issue
which Shares will be accepted in exchange at their fair market value on the date
of exercise. Certificates representing the Shares purchased by the Participant
shall be issued as soon as reasonably practicable after the Participant has
complied with the provisions hereof.

          6. TERM AND CONDITIONS OF SARS. Each SAR granted by the Board pursuant
to this Plan shall be evidenced by a SAR agreement in such form or forms as the
Board may from time to time prescribe (which agreements need not be identical)
containing provisions consistent with the Plan. Any right of the Company to
terminate the Participant's employment or status as an outside director,
consultant or advisor at any time, with or without cause, shall in no way be
restricted by the existence of this Plan, any SARs granted hereunder, or the SAR
agreement related thereto. SARs shall further be subject to the following terms
and conditions:

                    a. TERM OF SARS. Participants shall be awarded SARs for such
vesting periods greater than six (6) months as the Board may determine. At the
discretion of the Board, SARs may automatically mature on such dates as the
Board shall determine in advance and set forth in the SAR Agreement, or the
Participant may be given the right to exercise the SAR within a period set by
the Board. The maturity date or exercise period may begin no sooner than six (6)
months from the date of grant and end no later than ten (10) years from the date
of grant.

                    b. VALUE OF SARS. The value of a SAR shall be the excess of
the Maturity Value of the Shares covered thereby over the Base Value of the
Shares covered thereby. The method of determining the Base Value and Maturity
Value shall be set forth in the SAR Agreement. If the Maturity Value is less
than the Base Value, the value of the SAR shall be zero.

                                       3
<PAGE>   4
                    c. MATURITY OR EXERCISE. Upon maturity or exercise, the
Participant shall become entitled to receive, in cash or Shares or any
combination thereof as set forth in the SAR Agreement in the sole discretion of
the Board, the value of the SAR. If Shares are distributed in payment of a SAR,
the value of such distributed Shares shall be determined as of the maturity or
exercise date, even though the Shares may be distributed at a later date.

          7. TANDEM GRANTS. At the sole discretion of the Board, options and
SARs may be granted separately or in tandem. If designated as granted in tandem
by the Board, then the option and SAR shall be alternative, such that to the
extent the option is exercised, the corresponding SAR shall be extinguished, and
to the extent the SAR is exercised, the corresponding option shall be
extinguished.

          8. ASSIGNMENT OF OPTIONS AND SARS. During the lifetime of the
Participant, incentive stock options granted hereunder shall be exercisable only
by the Participant and shall not be assignable or transferable by the
Participant, whether voluntarily or by operation of law or otherwise, and no
other person shall acquire any rights therein. Only after an initial public
offering of the Shares, nonstatutory stock options and SARs may be transferable
by a Participant to or for the benefit of a family member, if permitted in the
option or SAR agreement.

          9. DEATH OF PARTICIPANT. In the event that a Participant shall die
while he/she is an employee, OUTSIDE DIRECTOR, consultant or advisor of the
Company and prior to the complete exercise of options or maturity of SARs
granted to him or her under the Plan, any such remaining options or SARs shall
be fully vested and may be exercised in whole or in part within one (1) year
after the date of the Participant's death and then only: (i) by the beneficiary
designated under the Participant's Beneficiary Designation Form as submitted to
the Company prior to the Participant's death (unless it is determined that such
designation would disqualify an option from treatment as an incentive stock
option), or in the absence of same, by the Participant's estate or by or on
behalf of such person or persons to whom the Participant's rights pass under his
will or the laws of descent and distribution, (ii) to the extent that the
Participant would have been entitled to exercise the option or SAR at the date
of his death had it been fully vested, and subject to all of the conditions on
exercise imposed by the Plan and the option or SAR agreement, and (iii) prior to
the expiration of the term of the option or SAR. In the case of SARs with fixed
maturity dates, if the Participant dies while he or she is an employee, outside
director, consultant or advisor of the Company such portion of the value of the
SAR as shall be set forth in the SAR Agreement shall be paid on terms set forth
in the SAR Agreement to the Participant's beneficiary designated under the
Participant's Beneficiary Designation Form as submitted to the Company prior to
the Participant's death, or in the absence of same, to the estate or to such
person or persons to whom the Participant's rights pass under his will or the
laws of descent and distribution.

          10. DISABILITY OF PARTICIPANT. In the event that a Participant's
employment or status as a consultant, outside director or advisor with the
Company terminates due to the Participant's permanent disability and prior to
the complete exercise or maturity of options or SARs granted to him or her under
the Plan, any such remaining options or SARs shall be fully vested and may be
exercised in whole or in part up to nine (9) months but not less than six (6)
months after the Participant's termination of employment or status as a
consultant, outside director or advisor, as the case may be. For purposes of
this Section 10, disability shall be determined under and

                                       4
<PAGE>   5

governed by the terms of the Company's Long-Term Disability Plan in effect on
the date of disability.

     11.  TERMINATION OF EMPLOYMENT.

                    a. An incentive stock option shall be exercisable, during
the lifetime of the Participant, only while he is an employee of the Company and
has been an employee continuously since the grant of the incentive stock option
or, subject to the option agreement, within three (3) months after termination
of his or her employment. In its sole discretion, the Board may provide in the
option agreement such further limitations on the survival of incentive stock
options, and such limitations on the survival of nonstatutory options and SARs
as it may determine; provided, however that all options shall be exercisable for
a minimum of sixty (60) days after termination of a Participant's employment
except in the case of termination for cause in which case the exercise period
shall lapse at termination.

                    For purposes of the Plan and related documents, an
Employee's employment shall be treated as having been terminated for "cause" if
it is terminated by the Company as a result of the Employee's (i) commission of
a felony; (ii) breach of a material fiduciary duty owed by the Employee to
Genencor International, Inc. or any of its subsidiaries; (iii) material and
repeated neglect of duties; (iv) intentional unauthorized disclosure to any
person of confidential information or trade secrets of a material nature
relating to the Company's business; or (v) having engaged in any conduct which
the Company's written rules, regulations or policies relating to employment
specify as constituting grounds for discharge.

                    b. Unless otherwise provided by the Board in the option or
SAR agreement, any option or SAR shall be exercisable on termination of
employment, outside director, consultant, or advisor status only to the extent
that the Participant would have been entitled to the exercise of the option or
maturity of the SAR at the time of the termination of such relationship; and
further, no option or SAR shall be exercisable or mature after the expiration of
the term thereof. The Board in its absolute discretion pursuant to rules set
forth in the agreement or otherwise, may accelerate the vesting and
exercisability of an option in order to allow its exercise by a terminating
Participant.

                    c. For purposes of this Section 11, an employment, outside
director, consultant or advisory relationship will be treated as continuing
during the period when a Participant is on military duty, sick leave or other
bona fide leave of absence if the period of such leave does not exceed ninety
(90) days, or, with respect to an employee, if longer, so long as a statute or
contract guarantees the Participant's right to re-employment with the Company.
When the period of leave exceeds ninety (90) days and the individual's right to
re-employment is not guaranteed either by statute or by contract, the employment
relationship will be deemed to have terminated on the ninety-first (91st) day of
such leave.

          12. ANTI-DILUTION PROVISIONS. The aggregate number and kind of Shares
available for options and SARs under the Plan, the number and kind of Shares
subject to any outstanding option, the option price of each outstanding option,
the number of SARs of a Participant, and the Maturity Value and Base Value of
each SAR, shall be proportionately adjusted by the Board for any increase,
decrease or change in the total outstanding Shares of the Company resulting from
a

                                       5

stock split, reverse stock split, stock dividend, recapitalization, combination,
reclassification, split-up, or similar transaction (but not by reason of the
issuance, sale or purchase of Shares by the Company in consideration for money,
services or property).

          13. WITHHOLDING OF TAX. There shall be deducted from each distribution
of cash under the Plan the amount of any tax required by any governmental
authority to be withheld and paid over by the Company to that governmental
authority for the account of the person entitled to the distribution.
Notwithstanding any other provision of this Plan, the Company shall not be
required to make, and Participants shall have no rights to, any distributions of
Shares or cash under this Plan and shall have no rights to exercise options
granted under this Plan until such obligations to withhold taxes have been
resolved to the satisfaction of the Company. In the event a distribution would
otherwise contain insufficient cash to cover such obligations to withhold taxes,
the Company may refrain from making any distribution or issuing any Shares to
the Participant under this Plan until the Participant has made arrangements
satisfactory to the Board for the payment of such obligations to withhold tax.
Nothing in this Section shall prevent the Company from withholding such tax from
any other compensation due to the Participant from the Company.

          14. RIGHTS AS A STOCKHOLDER. The Participant shall have no rights as a
stockholder with respect to the Shares purchased by him or her pursuant to the
exercise of an option or due him under a SAR until the date of the issuance to
him or her of a certificate of stock representing such Shares. No adjustment
shall be made for dividends or for distributions of any other kind with respect
to Shares for which the record date is prior to the date of the issuance to the
Participant of a certificate for the Shares.

          15. NOTICE OF EXERCISE. A condition of the exercise of an option or
the maturity of a SAR under the Plan shall be that the Participant, as well as
any transferee of an option granted to the Participant, shall sign the Notice of
Exercise document as presented to him by the Board, thereby agreeing to be bound
by its provisions. No Shares shall be issued unless SUCH document has been
signed and returned by the Participant and by any transferee of an option upon
exercise. The Board may, in its discretion, release Participants from this
requirement in the event that Shares become publicly traded.

          16. ADOPTION, APPROVAL, AND TERM OF PLAN. The Plan shall take effect
on final adoption of the Plan by both the Board and the stockholders of record
of the Company. The Plan shall remain in effect until all Shares subject to
issuance hereunder have been purchased pursuant to options granted under the
Plan and all SARs authorized herein have been granted and have matured or been
exercised, provided that all options and SARs under the Plan must be granted
within ten (10) years from the later of the date that the Plan is adopted by the
Board or the date that it is approved by the stockholders of the Company.

          17. AMENDMENT AND TERMINATION OF PLAN. The Board, without further
approval of the stockholders of the Company, may at any time suspend or
terminate the Plan or may amend it from time to time in any manner; provided,
however, that no amendment shall be effective without prior approval of the
stockholders of the Company which would (i) except as provided in Section 12
hereof, increase the maximum number of Shares which may be issued with respect
to options and SARs under the Plan, (ii) change the eligibility requirements for
individuals entitled

                                       6
<PAGE>   7

to receive options or SARs under the Plan, (iii) extend the period for
granting options or SARs, or (iv) materially increase benefits accruing to
Participants hereunder. Provided, further, that no amendment or termination of
the Plan shall eliminate accrued rights of a Participant in vested options or
SARs.

     18.  EFFECT OF ACQUISITION, REORGANIZATION, OR LIQUIDATION.

          a. Notwithstanding any provision to the contrary in this Plan or in
any agreement evidencing options or SARs granted hereunder, all options and SARs
with exercise periods then currently outstanding shall become immediately
exercisable in full and remain exercisable until their expiration in accordance
with their respective terms upon the occurrence of either of the following
events:

               (i) the first purchase of the Shares pursuant to a tender or
exchange offer which is intended to effect the acquisition of more than forty
percent (40%) of the voting power of the Company (other than a tender or
exchange offer made by the Company); or

               (ii) approval by the Company's stockholders of (A) a merger or
consolidation of the Company with or into another corporation (other than a
merger or consolidation in which the Company is the surviving corporation and
which does not result in any reclassification or reorganization of the Shares),
(B) a sale or disposition of all or substantially all of the Company's assets,
or (C) a plan of complete liquidation or dissolution of the Company.

          b. With respect to SARs with fixed maturity dates, the maturity date
of all such SARs shall be the earlier of their normal maturity dates or:

               (i) the date of the first purchase of any Shares pursuant to a
tender or exchange offer which is intended to effect the acquisition of more
than forty percent (40%) of the voting power of the Company (other than a tender
or exchange offer made by the Company),

               (ii) the effective date of any merger or consolidation of the
Company with or into another corporation (other than a merger or consolidation
in which the Company is the surviving corporation and which does not result in
any reclassification or reorganization of the Shares),

               (iii) the date of transfer of all or substantially all of the
Company's assets pursuant to a sale or other disposition, or

               (iv) the date of the first distribution from the Company to
stockholders pursuant to a plan of complete liquidation or dissolution of the
Company.

          c. Any provision hereof to the contrary notwithstanding, in the event
the Company is a party to an agreement to sell all or substantially all of its
assets, a merger or other reorganization, all outstanding options and SARs shall
be subject to the agreement of sale, merger, or other reorganization which may
provide, without limitation, for the assumption of outstanding options or SARs
by the surviving corporation or its parent, for their continuation by

                                       7
<PAGE>   8

the Company (if it is a surviving corporation), for accelerated termination
(subject to the accelerated vesting described herein), or for settlement in
cash.

          d. Subsections 18(a), 18(b) and 18(c) shall not apply to any
transaction otherwise described in Subsections 18(a) or 18(b) between the
stockholders of the Company on the date of the adoption of the Plan (the
"Stockholders") or between the Company and either or both of its Stockholders.

     19. ADMINISTRATION. The Plan shall be administered by the Board as it may
be constituted from time to time. After the initial public offering of the
Shares, the Plan shall be administered by the Board or at least two (2) members
of the Board selected by the Board, in compliance with the requirements of
Section 162(m) of the Internal Revenue Code, and the requirements of Rule 16b-3
of the Securities Exchange Act of 1934. Decisions of the Board concerning the
interpretation and construction of any provisions of the Plan or of any option
or SAR granted pursuant to the Plan shall be final. The Company shall effect the
grant of options and SARs under the Plan in accordance with the decisions of the
Board, which may, from time to time, adopt rules and regulations for carrying
out the Plan. For purposes of the Plan, an option or a SAR shall be deemed to be
granted when the written agreement for the same is signed on behalf of the
Company by its duly authorized officer or representative. Subject to the express
provisions of the Plan, the Board shall have the authority, in its discretion
and without limitation: to determine the individuals to receive options and
SARs, whether an option is intended to be an incentive stock option or a
nonstatutory stock option, the times when such individuals shall receive such
options or SARs, the number of Shares to be subject to each option or SAR, the
term of each option or SAR, the date when each option or SAR shall become
exercisable, or when each SAR will mature, whether an option or SAR shall be
exercisable or mature in whole or in part in installments, the form in which
payment of a SAR will be made (i.e., cash, Shares, or any combination thereof),
the number of Shares to be subject to each installment, the date each
installment shall become exercisable or mature, the term of each installment and
the option price of each option, to accelerate the date of exercise of any
option or SAR or installment thereof, and to make all other determinations
necessary or advisable for administering the Plan.

     20. RESERVATION OF SHARES. Except as provided herein below, the Company
shall be under no obligation to reserve Shares to fill options or SARs. The
grant of options to individuals hereunder shall not be construed to constitute
the establishment of a trust of such Shares and no particular Shares shall be
identified as optioned and reserved for individuals hereunder. The Company shall
be deemed to have complied with the terms of the Plan if, at the time of
issuance and delivery pursuant to the exercise of an option, it has a sufficient
number of Shares authorized and unissued or in its treasury which may then be
appropriated and issued for purposes of the Plan, irrespective of the date when
such Shares were authorized. The SARs shall be used solely as a device for the
measurement and determination of the amount to be paid to Participants as
provided in the Plan. The SARs shall not constitute or be treated as property or
as a trust fund of any kind. All amounts at any time attributable to the SARs
shall be and remain the sole property of the Company and all Participants'
rights hereunder are limited to the rights to receive cash or Shares of the
Company as provided in this Plan and any SAR agreement entered into hereunder.

     21. INFORMATION OBLIGATION. Prior to the initial public offering of the
Shares, to the extent required by applicable law, the Company shall deliver
financial statements to Participants at least annually. This Section 21 shall
not apply to key employees whose duties in connection with the Company assure
them access to equivalent information.

     22. APPLICATION OF PROCEEDS. The proceeds of the sale of Shares by the
Company under the Plan will constitute general funds of the Company and may be
used by the Company for any purpose.

     23. GENDER. As used in this Plan, masculine pronouns shall be deemed to
include the feminine, and vice versa.

     24. GOVERNING LAW. This Plan, its validity, interpretation, and
administration, shall be governed in accordance with the laws of the State of
Delaware, except to the extent that such laws may be preempted by Federal law.
