              FAIR ISAAC CORPORATION 1992 LONG-TERM INCENTIVE PLAN
                        AS AMENDED EFFECTIVE MAY 15, 2005


ARTICLE 1. INTRODUCTION.

The Plan was adopted by the Board on November 23, 1992, subject to approval by
the Company's stockholders. The Board approved amendments to the Plan on
November 21, 1995 and on November 16, 2001, subject to approval by the Company's
stockholders. The Plan was also amended by either the Board or the Committee on
December 23, 1996, on November 25, 1997, on November 19, 1999, on November 21,
2000, on April 1, 2003, on August 26, 2003, and on May 15, 2005. All share
amounts in this restatement have been adjusted to reflect stock splits on June
26, 1995, on June 4, 2001, on June 5, 2002, and on March 10, 2004. The purpose
of the Plan is to promote the long-term success of the Company and the creation
of stockholder value by (a) encouraging Key Employees to focus on critical
long-range objectives, (b) encouraging the attraction and retention of Key
Employees with exceptional qualifications and (c) linking Key Employees directly
to stockholder interests through increased stock ownership. The Plan seeks to
achieve this purpose by providing for Awards in the form of Restricted Shares,
Stock Units, Options (which may constitute incentive stock options or
nonstatutory stock options) or stock appreciation rights.

The Plan shall be governed by, and construed in accordance with, the laws of the
State of California.

ARTICLE 2. ADMINISTRATION.


               2.1 COMMITTEE COMPOSITION. The Plan shall be administered by the
Committee. The Committee shall consist of two or more Outside Directors who
shall be appointed by the Board (although Committee functions may be delegated
by the Committee to an officer or officers to the extent that the Awards relate
to persons who are not subject to the reporting requirements of Section 16 of
the Exchange Act)."

               2.2 COMMITTEE RESPONSIBILITIES. The Committee shall (a) unless
delegated to an officer or officers in accordance with Section 2.1, select the
Key Employees who are to receive Awards under the Plan and determine the type,
number, vesting requirements and other conditions of such Awards, (b) interpret
the Plan and (c) make all other decisions relating to the operation of the Plan.
The Committee may adopt such rules or guidelines as it deems appropriate to
implement the Plan. The Committee's determinations under the Plan shall be final
and binding on all persons."

ARTICLE 3. SHARES AVAILABLE FOR GRANTS.

              3.1 BASIC LIMITATION. Any Common Shares issued pursuant to the
Plan may be authorized but unissued shares or treasury shares. The aggregate
number of Restricted Shares, Stock Units and Options awarded under the Plan
shall not exceed 4,725,000 plus the number of Common Shares remaining available
for awards under the Company's 1987 Stock Option Plan and Stock Option Plan for
Non-employee Directors (the "Prior Plans") at the time this Plan is first
approved by the stockholders. (No additional grants shall be made under the
Prior Plans after this Plan has been approved by the stockholders.) Effective
October 1, 1997, and on each October 1 thereafter for the remaining term of the
Plan, the aggregate number of Shares which may be issued under the Plan to
individuals shall be increased by a number of Common Shares equal to 4 percent
of the total number of Common Shares outstanding at the end of the most recently
concluded fiscal year. Any Common Shares that have been reserved but not issued
as Restricted Shares, Stock Units or Options during any fiscal year shall remain
available for grant during any subsequent fiscal year. Notwithstanding the
foregoing, no more than 5,062,500 Common Shares shall be available for the grant
of ISOs for the remaining term of the Plan. The aggregate number of Common
Shares which may be issued under the Plan shall at all times be subject to
adjustment pursuant to Article 10.

               3.2 ADDITIONAL SHARES. If any Stock Units or Options are
forfeited or if any Options terminate for any other reason before being
exercised, then such Stock Units or Options shall again become available for
Awards under the Plan. If any options under the Prior Plans are forfeited or
terminate for any other reason before being exercised, then such options shall
become available for additional Awards under this Plan. However, if Options are
surrendered upon the exercise of related SARs, then such Options shall not be
restored to the pool available for Awards.

               3.3 DIVIDEND EQUIVALENTS. Any dividend equivalents distributed
under the Plan shall not be applied against the number of Restricted Shares,
Stock Units or Options available for Awards, whether or not such dividend
equivalents are converted into Stock Units.

              3.4 OUTSIDE DIRECTOR OPTION LIMITATIONS. Notwithstanding the
limitations set forth in Section 3.1 above, effective February 1, 2000, there
shall be an additional 506,250 aggregate number of Options available for awards
under the Plan to Outside Directors as further described in Section 4.2 below.

ARTICLE 4. ELIGIBILITY.

               4.1 GENERAL RULES. Only Key Employees shall be eligible for
designation as Participants by the Committee. Key Employees who are Outside
Directors shall only be eligible for the grant of the NSOs described in Section
4.2.

               4.2 OUTSIDE DIRECTORS. Any other provision of the Plan
notwithstanding, the participation of Outside Directors in the Plan shall be
subject to the following restrictions:

               (a) Outside Directors shall receive no Awards other than the NSOs
     described in this Section 4.2.


                                      -6-
<PAGE>


               (b)(i) Each person who first becomes an Outside Director on or
     after the date of the Company's 2000 annual meeting of stockholders shall,
     upon becoming an Outside Director, receive an NSO covering 30,000 Common
     Shares (subject to adjustment under Article 10), hereinafter referred to as
     an "Initial Grant". Such Initial Grant shall become exercisable in
     increments of 6,000 shares (subject to adjustment under Article 10) on each
     of the first through fifth anniversaries of the date of grant.

               (ii) Each Outside Director who was acting as an Outside Director
     prior to the Company's 2000 annual meeting of stockholders shall be
     entitled to receive an NSO grant of Common Shares in an amount sufficient
     to increase his or her Initial Grant to 30,000 Common Shares effective as
     of the date of such annual meeting.

               (iii) On the date of each annual meeting of stockholders of the
     Company held on or after January 1, 2000, each Outside Director who has
     been an Outside Director at least since the prior annual meeting shall
     receive an NSO covering 11,250 Common Shares (subject to adjustment under
     Article 10), hereinafter referred to as an "Annual Grant." Such Annual
     Grants shall be exercisable in full on the date of grant.

               (iv) On the date of each annual meeting of stockholders of the
     Company held on or after January 1, 2000, each Outside Director who chairs
     a standing committee at the direction of the Chairman of the Board shall
     receive an NSO covering an additional 1,500 Common Shares (subject to
     Adjustment under Article 10) hereinafter referred to as a "Committee
     Grant". Such Committee Grant shall be exercisable in full on the date of
     grant.

               (v) On the date of each annual meeting of the stockholders of the
     Company held on or after January 1, 2002, each Outsider Director who has,
     prior to the date of such annual meeting, elected to receive an NSO in lieu
     of any cash paid to such Outside Director by virtue of such Outside
     Director serving as a member of the Company's Board of Directors (the
     "Annual Cash Retainer"), shall receive an NSO covering the number of Common
     Shares equal to the Annual Cash Retainer paid to Outside Directors,
     multiplied by two, divided by the Fair Market Value of a Common Share on
     the date of grant, such grant shall be hereinafter referred to as a
     "Retainer Grant." If the Annual Cash Retainer payable to an Outside
     Director is increased during the term for which such Outside Director has
     made an election to receive the Retainer Grant and such Outside Director
     continues to serve as a director of the Company on the date such Annual
     Cash Retainer is increased, an additional NSO shall be granted, calculated
     using the same formula as the Retainer Grant based on the increase in the
     Annual Cash Retainer with the date of grant being the date of the increase
     in the Annual Cash Retainer. Retainer Grants shall be exercisable in full
     on the date of grant.

               (c) All NSOs granted to an Outside Director under this Section
     4.2 shall also become exercisable in full in the event of the termination
     of such Outside Director's service for any reason.

               (d) The Exercise Price under all NSOs granted to an Outside
     Director under this Section 4.2 shall be equal to 100% of the Fair Market
     Value of a Common Share on the date of grant, payable in one of the forms
     described in Sections 6.1, 6.2, 6.3 and 6.4.

               (e) All NSOs granted to an Outside Director under this Section
     4.2 shall terminate on the earliest of (i) the 10th anniversary of the date
     of grant or (ii) the date 12 months after the termination of such Outside
     Director's service for any reason.


                                      -7-
<PAGE>


               4.3 TEN-PERCENT STOCKHOLDERS. A Key Employee who owns more than
10% of the total combined voting power of all classes of outstanding stock of
the Company or any of its Subsidiaries shall not be eligible for the grant of an
ISO unless the requirements set forth in section 422(c)(6) of the Code are
satisfied.

               4.4 LIMITATION ON OPTION GRANTS. No person shall receive Options
for more than 562,500 Common Shares (subject to adjustment under Article 10) in
any single fiscal year of the Company.

ARTICLE 5. OPTIONS.

               5.1 STOCK OPTION AGREEMENT. Each grant of an Option under the
Plan shall be evidenced by a Stock Option Agreement between the Optionee and the
Company. Such Option shall be subject to all applicable terms of the Plan and
may be subject to any other terms that are not inconsistent with the Plan. The
Stock Option Agreement shall specify whether the Option is an ISO or an NSO. The
provisions of the various Stock Option Agreements entered into under the Plan
need not be identical.

               5.2 AWARDS NONTRANSFERABLE. Except as provided in Article 15(ii),
no Option granted under the Plan shall be transferable by the Optionee other
than by will, by a beneficiary designation executed by the Optionee and
delivered to the Company or by the laws of descent and distribution. An Option
may be exercised during the lifetime of the Optionee only by him or her or by
his or her guardian or legal representative. No Option or interest therein may
be transferred, assigned, pledged or hypothecated by the Optionee during his or
her lifetime, whether by operation of law or otherwise, or be made subject to
execution, attachment or similar process.

               5.3 NUMBER OF SHARES. Each Stock Option Agreement shall specify
the number of Shares subject to the Option and shall provide for the adjustment
of such number in accordance with Article 10.

               5.4 EXERCISE PRICE. Each Stock Option Agreement shall specify the
Exercise Price. The Exercise Price shall not be less than 100% of the Fair
Market Value of a Common Share on the date of grant.

               5.5 EXERCISABILITY AND TERM. Each Stock Option Agreement shall
specify the date when all or any installment of the Option is to become
exercisable. The Stock Option Agreement shall also specify the term of the
Option; provided that the term of an ISO shall in no event exceed 10 years from
the date of grant. A Stock Option Agreement may provide for accelerated
exercisability in the event of the Optionee's death, disability or retirement or
other events and may provide for expiration prior to the end of its term in the
event of the termination of the Optionee's service. NSOs may also be awarded in
combination with Restricted Shares or Stock Units, and such an Award may provide
that the NSOs will not be exercisable unless the related Restricted Shares or
Stock Units are forfeited.

               5.6 EFFECT OF CHANGE IN CONTROL. The Committee may determine, at
the time of granting an Option or thereafter, that such Option (and any SARs
included therein) shall become fully exercisable as to all Common Shares subject
to such Option in the event that a


                                      -8-
<PAGE>


Change in Control occurs with respect to the Company. If the Committee finds
that there is a reasonable possibility that, within the succeeding six months, a
Change in Control will occur with respect to the Company, then the Committee may
determine that any or all outstanding Options (and any SARs included therein)
shall become fully exercisable as to all Common Shares subject to such Options.

               5.7 MODIFICATION OR ASSUMPTION OF OPTIONS. Within the limitations
of the Plan, the Committee may modify, extend or assume outstanding options or
may accept the cancellation of outstanding options (whether granted by the
Company or by another issuer) in return for the grant of new options for the
same or a different number of shares and at the same or a different exercise
price. The foregoing notwithstanding, no modification of an Option shall,
without the consent of the Optionee, alter or impair his or her rights or
obligations under such Option.

ARTICLE 6. PAYMENT FOR OPTION SHARES.

               6.1 GENERAL RULE. The entire Exercise Price of Common Shares
issued upon exercise of Options shall be payable in cash at the time when such
Common Shares are purchased, except as follows:

                              (a) In the case of an ISO granted under the Plan,
               payment shall be made only pursuant to the express provisions of
               the applicable Stock Option Agreement. The Stock Option Agreement
               may specify that payment may be made in any form(s) described in
               this Article 6.

                              (b) In the case of an NSO, the Committee may at
               any time accept payment in any form(s) described in this Article
               6.

Notwithstanding any provision in this Article 6 or in an Optionee's Stock Option
Agreement, an Optionee, shall not be permitted to exercise an Option in any
manner which would violate applicable state and federal laws, including, without
limitation, the Sarbanes-Oxley Act of 2002.

               6.2 SURRENDER OF STOCK. To the extent that this Section 6.2 is
applicable, payment for all or any part of the Exercise Price may be made with
Common Shares which have already been owned by the Optionee for more than twelve
months. Such Common Shares shall be valued at their Fair Market Value on the
date when the new Common Shares are purchased under the Plan.

               6.3 EXERCISE/SALE. To the extent that this Section 6.3 is
applicable, payment may be made by the delivery (on a form prescribed by the
Company) of an irrevocable direction to a securities broker or other party
approved by the Company to sell Common Shares and to deliver all or part of the
sales proceeds to the Company in payment of all or part of the Exercise Price
and any withholding taxes.

               6.4 EXERCISE/PLEDGE. To the extent that this Section 6.4 is
applicable, payment may be made by the delivery (on a form prescribed by the
Company) of an irrevocable direction to pledge Common Shares to a securities
broker or lender approved by the


                                      -9-
<PAGE>


Company, as security for a loan, and to deliver all or part of the loan proceeds
to the Company in payment of all or part of the Exercise Price and any
withholding taxes.

                  6.5 OTHER FORMS OF PAYMENT. To the extent that this Section
6.5 is applicable, payment may be made in any other form that is consistent with
applicable laws, regulations and rules.

ARTICLE 7. STOCK APPRECIATION RIGHTS.

               7.1 GRANT OF SARS. At the discretion of the Committee, an SAR may
be included in each Option granted under the Plan, other than the NSOs granted
to Outside Directors under Section 4.2. Such SAR shall entitle the Optionee (or
any person having the right to exercise the Option after his or her death) to
surrender to the Company, unexercised, all or any part of that portion of the
Option which then is exercisable and to receive from the Company Common Shares
or cash, or a combination of Common Shares and cash, as the Committee shall
determine. If an SAR is exercised, the number of Common Shares remaining subject
to the related Option shall be reduced accordingly, and vice versa. The amount
of cash and/or the Fair Market Value of Common Shares received upon exercise of
an SAR shall, in the aggregate, be equal to the amount by which the Fair Market
value (on the date of surrender) of the Common Shares subject to the surrendered
portion of the Option exceeds the Exercise Price. In no event shall any SAR be
exercised if such Fair Market Value does not exceed the Exercise Price. An SAR
may be included in an ISO only at the time of grant but may be included in an
NSO at the time of grant or at any subsequent time, but not later than six
months before the expiration of such NSO.

               7.2 EXERCISE OF SARS. An SAR may be exercised to the extent that
the Option in which it is included is exercisable, subject to the restrictions
imposed by Rule 16b-3 (or its successor) under the Exchange Act, if applicable.
If, on the date when an Option expires, the Exercise Price under such Option is
less than the Fair Market Value on such date but any portion of such Option has
not been exercised or surrendered, then any SAR included in such Option shall
automatically be deemed to be exercised as of such date with respect to such
portion. An Option granted under the Plan may provide that it will be
exercisable as an SAR only in the event of a Change in Control.


ARTICLE 8. RESTRICTED SHARES AND STOCK UNITS.

               8.1 TIME, AMOUNT AND FORM OF AWARDS. Restricted Shares or Stock
Units with respect to an Award Year may be granted during such Award Year or at
any time thereafter. Awards under the Plan may be granted in the form of
Restricted Shares, in the form of Stock Units, or in any combination of both.
Restricted Shares or Stock Units may also be awarded in combination with NSOs,
and such an Award may provide that the Restricted Shares or Stock Units will be
forfeited in the event that the related NSOs are exercised.

               8.2 PAYMENT FOR AWARDS. To the extent that an Award is granted in
the form of newly issued Restricted Shares, the Award recipient shall be
required to pay the Company in lawful money of the U.S. an amount equal to the
par value of such Restricted Shares. To the


                                      -10-
<PAGE>


extent that an Award is granted in the form of Stock Units or treasury shares,
no cash consideration shall be required of Award recipients.

               8.3 VESTING CONDITIONS. Each Award of Restricted Shares or Stock
Units shall become vested, in full or in installments, upon satisfaction of the
conditions specified in the Stock Award Agreement. A Stock Award Agreement may
provide for accelerated vesting in the event of the Participant's death,
disability or retirement or other events. The Committee may determine, at the
time of making an Award or thereafter, that such Award shall become fully vested
in the event that a Change in Control occurs with respect to the Company.

               8.4 FORM AND TIME OF SETTLEMENT OF STOCK UNITS. Settlement of
vested Stock Units may be made in the form of cash, in the form of Common
Shares, or in any combination of both. Methods of converting Stock Units into
cash may include (without limitation) a method based on the average Fair Market
Value of Common Shares over a series of trading days. Vested Stock Units may be
settled in a lump sum or in installments. The distribution may occur or commence
when all vesting conditions applicable to the Stock Units have been satisfied or
have lapsed, or it may be deferred to any later date. The amount of a deferred
distribution may be increased by an interest factor or by dividend equivalents.
Until an Award of Stock Units is settled, the number of such Stock Units shall
be subject to adjustment pursuant to Article 10.

               8.5 DEATH OF RECIPIENT. Any Stock Units Award that becomes
payable after the recipient's death shall be distributed to the recipient's
beneficiary or beneficiaries. Each recipient of a Stock Units Award under the
Plan shall designate one or more beneficiaries for this purpose by filing the
prescribed form with the Company. A beneficiary designation may be changed by
filing the prescribed form with the Company at any time before the Award
recipient's death. If no beneficiary was designated or if no designated
beneficiary survives the Award recipient, then any Stock Units Award that
becomes payable after the recipient's death shall be distributed to the
recipient's estate.

               8.6 CREDITORS' RIGHTS. A holder of Stock Units shall have no
rights other than those of a general creditor of the Company. Stock Units
represent an unfunded and unsecured obligation of the Company, subject to the
terms and conditions of the applicable Stock Award Agreement.

ARTICLE 9. VOTING AND DIVIDEND RIGHTS.

               9.1 RESTRICTED SHARES. The holders of Restricted Shares awarded
under the Plan shall have the same voting, dividend and other rights as the
Company's other stockholders. A Stock Award Agreement, however, may require that
the holders of Restricted Shares invest any cash dividends received in
additional Restricted Shares. Such additional Restricted Shares shall be subject
to the same conditions and restrictions as the Award with respect to which the
dividends were paid. Such additional Restricted Shares shall not reduce the
number of Common Shares available under Article 3.

               9.2 STOCK UNITS. The holders of Stock Units shall have no voting
rights. Prior to settlement or forfeiture, any Stock Unit awarded under the Plan
shall carry with it a right to dividend equivalents. Such right entitles the
holder to be credited with an amount equal to all cash dividends paid on one
Common Share while the Stock Unit is outstanding. Dividend


                                      -11-
<PAGE>


equivalents may be converted into additional Stock Units. Settlement of dividend
equivalents may be made in the form of cash, in the form of Common Shares, or in
a combination of both. Prior to distribution, any dividend equivalents which are
not paid shall be subject to the same conditions and restrictions as the Stock
Units to which they attach.

ARTICLE 10. PROTECTION AGAINST DILUTION.

               10.1 ADJUSTMENTS. In the event of a subdivision of the
outstanding Common Shares, a declaration of a dividend payable in Common Shares,
a declaration of a dividend payable in a form other than Common Shares in an
amount that has a material effect on the price of Common Shares, a combination
or consolidation of the outstanding Common Shares (by reclassification or
otherwise) into a lesser number of Common Shares, a recapitalization, a spinoff
or a similar occurrence, the Committee shall make appropriate adjustments in one
or more of (a) the number of Options, Restricted Shares and Stock Units
available for future Awards under Article 3, (b) the number of NSOs to be
granted to Outside Directors under Section 4.2, (c) the number of Stock Units
included in any prior Award which has not yet been settled, (d) the number of
Common Shares covered by each outstanding Option or (e) the Exercise Price under
each outstanding Option. Except as provided in this Article 10, a Participant
shall have no rights by reason of any issue by the Company of stock of any class
or securities convertible into stock of any class, any subdivision or
consolidation of shares of stock of any class, the payment of any stock dividend
or any other increase or decrease in the number of shares of stock of any class.

               10.2 REORGANIZATIONS. In the event that the Company is a party to
a merger or other reorganization, outstanding Options, Restricted Shares and
Stock Units shall be subject to the agreement of merger or reorganization. Such
agreement may provide, without limitation, for the assumption of outstanding
Awards by the surviving corporation or its parent, for their continuation by the
Company (if the Company is a surviving corporation), for accelerated vesting or
for settlement in cash.

ARTICLE 11. LONG-TERM PERFORMANCE AWARDS.

The Company may grant long-term performance awards under other plans or
programs. Such awards may be settled in the form of Common Shares issued under
this Plan. Such Common Shares shall be treated for all purposes under the Plan
like Common Shares issued in settlement of Stock Units and shall reduce the
number of Common Shares available under Article 3.

ARTICLE 12. LIMITATION ON RIGHTS.

               12.1 RETENTION RIGHTS. Neither the Plan nor any award granted
under the Plan shall be deemed to give any individual a right to remain an
employee or director of the Company or a Subsidiary. The Company and its
Subsidiaries reserve the right to terminate the service of any employee or
director at any time, with or without cause, subject to applicable laws, the
Company's certificate of incorporation and by-laws and a written employment
agreement (if any).

               12.2 STOCKHOLDERS' RIGHTS. A Participant shall have no dividend
rights, voting rights or other rights as a stockholder with respect to any
Common Shares covered by his or


                                      -12-
<PAGE>


her Award prior to the issuance of a stock certificate for such Common Shares.
No adjustment shall be made for cash dividends or other rights for which the
record date is prior to the date when such certificate is issued, except as
expressly provided in Articles 8, 9 and 10.

               12.3 REGULATORY REQUIREMENTS. Any other provision of the Plan
notwithstanding, the obligation of the Company to issue Common Shares under the
Plan shall be subject to all applicable laws, rules and regulations and such
approval by any regulatory body as may be required. The Company reserves the
right to restrict, in whole or in part, the delivery of Common Shares pursuant
to any Award prior to the satisfaction of all legal requirements relating to the
issuance of such Common Shares, to their registration, qualification or listing
or to an exemption from registration, qualification or listing.

ARTICLE 13. LIMITATION ON PAYMENTS.

               13.1 BASIC RULE. Any provision of the Plan to the contrary
notwithstanding, in the event that the independent auditors most recently
selected by the Board (the "Auditors") determine that any payment or transfer by
the Company to or for the benefit of a Key Employee, whether paid or payable (or
transferred or transferable) pursuant to the terms of this Plan or otherwise (a
"Payment"), would be non-deductible by the Company for federal income tax
purposes because of the provisions concerning "excess parachute payments" in
section 280G of the Code, then the aggregate present value of all Payments shall
be reduced (but not below zero) to the Reduced Amount; provided that the
Committee, at the time of making an Award under this Plan or at any time
thereafter, may specify in writing that such Award shall not be so reduced and
shall not be subject to this Article 13. For purposes of this Article 13, the
"Reduced Amount" shall be the amount, expressed as a present value, which
maximizes the aggregate present value of the Payments without causing any
Payment to be nondeductible by the Company because of section 280G of the Code.

               13.2 REDUCTION OF PAYMENTS. If the Auditors determine that any
Payment would be nondeductible by the Company because of section 280G of the
Code, then the Company shall promptly give the Key Employee notice to that
effect and a copy of the detailed calculation thereof and of the Reduced Amount,
and the Key Employee may then elect, in his or her sole discretion, which and
how much of the Payments shall be eliminated or reduced (as long as after such
election the aggregate present value of the Payments equals the Reduced Amount)
and shall advise the Company in writing of his or her election within 10 days of
receipt of notice. If no such election is made by the Key Employee within such
10-day period, then the Company may elect which and how much of the Payments
shall be eliminated or reduced (as long as after such election the aggregate
present value of the Payments equals the Reduced Amount) and shall notify the
Key Employee promptly of such election. For purposes of this Article 13, present
value shall be determined in accordance with section 280G(d)(4) of the Code. All
determinations made by the Auditors under this Article 13 shall be binding upon
the Company and the Key Employee and shall be made within 60 days of the date
when a payment becomes payable or transferable. As promptly as practicable
following such determination and the elections hereunder, the Company shall pay
or transfer to or for the benefit of the Key Employee such amounts as are then
due to him or her under the Plan and shall promptly pay or transfer to or for
the benefit of the Key Employee in the future such amounts as become due to him
or her under the Plan.


                                      -13-
<PAGE>


               13.3 OVERPAYMENTS AND UNDERPAYMENTS. As a result of uncertainty
in the application of section 280G of the Code at the time of an initial
determination by the Auditors hereunder, it is possible that Payments will have
been made by the Company which should not have been made (an "Overpayment") or
that additional Payments which will not have been made by the Company could have
been made (an "Underpayment"), consistent in each case with the calculation of
the Reduced Amount hereunder. In the event that the Auditors, based upon the
assertion of a deficiency by the Internal Revenue Service against the Company or
the Key Employee which the Auditors believe has a high probability of success,
determine that an Overpayment has been made, such Overpayment shall be treated
for all purposes as a loan to the Key Employee which he or she shall repay to
the Company, together with interest at the applicable federal rate provided in
section 7872(f)(2) of the Code; provided, however, that no amount shall be
payable by the Key Employee to the Company if and to the extent that such
payment would not reduce the amount which is subject to taxation under section
4999 of the Code. In the event that the Auditors determine that an Underpayment
has occurred, such Underpayment shall promptly be paid or transferred by the
Company to or for the benefit of the Key Employee, together with interest at the
applicable federal rate provided in section 7872(f)(2) of the Code.

               13.4 RELATED CORPORATIONS. For purposes of this Article 13, the
term "Company" shall include affiliated corporations to the extent determined by
the Auditors in accordance with section 280G(d)(5) of the Code.

ARTICLE 14. WITHHOLDING TAXES.

               14.1 GENERAL. To the extent required by applicable federal,
state, local or foreign law, the recipient of any payment or distribution under
the Plan shall make arrangements satisfactory to the Company for the
satisfaction of any withholding tax obligations that arise by reason of the
receipt or vesting of such payment or distribution. The Company shall not be
required to issue any Common Shares or make any cash payment under the Plan
until such obligations are satisfied.

               14.2 SHARE WITHHOLDING. The Committee may permit a Participant to
satisfy all or part of his or her withholding or income tax obligations by
having the Company withhold a portion of any Common Shares that otherwise would
be issued to him or her or by surrendering a portion of any Common Shares that
previously were issued to him or her. Such Common Shares shall be valued at
their Fair Market Value on the date when taxes otherwise would be withheld in
cash. Any payment of taxes by assigning Common Shares to the Company may be
subject to restrictions, including any restrictions required by rules of the
Securities and Exchange Commission.

ARTICLE 15. ASSIGNMENT OR TRANSFER OF AWARDS.

               (i) Except as provided in Article 14, any Award granted under the
Plan shall not be anticipated, assigned, attached, garnished, optioned,
transferred or made subject to any creditor's process, whether voluntarily,
involuntarily or by operation of law. Any act in violation of this Article 15
shall be void. However, this Article 15 shall not preclude a Participant from
designating a beneficiary who will receive any undistributed Awards in the event
of the Participant's death, nor shall it preclude a transfer by will or by the
laws of descent and distribution. In addition, neither this Article 15 nor any
other provision of the Plan


                                      -14-
<PAGE>


shall preclude a Participant from transferring or assigning Restricted Shares or
Stock Units to (a) the trustee of a trust that is revocable by such Participant
alone, both at the time of the transfer or assignment and at all times
thereafter prior to such Participant's death, or (b) the trustee of any other
trust to the extent approved in advance by the Committee in writing. A transfer
or assignment of Restricted Shares or Stock Units from such trustee to any
person other than such Participant shall be permitted only to the extent
approved in advance by the Committee in writing, and Restricted Shares or Stock
Units held by such trustee shall be subject to all of the conditions and
restrictions set forth in the Plan and in the applicable Stock Award Agreement,
as if such trustee were a party to such Agreement.

               (ii) Notwithstanding paragraph (i) above, an NSO or portion
thereof may be transferred by the Optionee by gift to (a) the Optionee's
immediate family, (b) a partnership or limited liability company consisting
solely of the Optionee and/or immediate family, or (c) to a trust established
for the benefit of the Optionee and/or one or more members of the immediate
family of the Optionee (including a charitable remainder trust whose income
beneficiaries consist solely of such persons), or (d) as provided in the
Optionee's Stock Option Agreement or with consent of the Board or Committee to
any other person or entity to which a transfer of compensatory securities is
permitted under the applicable rules for a Form S-8 registration statement,
provided that such transfer will not be effective until notice of such transfer
is delivered to the Corporation. For purposes of this paragraph (ii) "immediate
family" means spouse, children and grandchildren. An Option or portion thereof
may also be transferred pursuant to a domestic relations order of a court of
competent jurisdiction.

ARTICLE 16. FUTURE OF THE PLAN.

               16.1 TERM OF THE PLAN. The Plan, as set forth herein, shall
become effective upon approval by the Stockholders of the Company. The Plan
shall remain in effect until February 4, 2012, unless terminated earlier
pursuant to Section 16.2, except that no ISOs shall be granted after November
15, 2011.

               16.2 AMENDMENT OR TERMINATION. The Board or the Committee may, at
any time and for any reason, amend or terminate the Plan. An amendment of the
Plan shall be subject to the approval of the Company's stockholders only to the
extent required by applicable laws, regulations or rules. No Awards shall be
granted under the Plan after the termination thereof. The termination of the
Plan, or any amendment thereof, shall not affect any Option previously granted
under the Plan.
