                                    RECITALS

        Borrower has requested that Bank extend or continue credit to Borrower
as described below, and Bank has agreed to provide such credit to Borrower on
the terms and conditions contained herein.

        NOW, THEREFORE, for valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, Bank and Borrower hereby agree as follows:

                                    ARTICLE I

                                  CREDIT TERMS

        SECTION 1.1. LINE OF CREDIT.

        (a)     Line of Credit. Subject to the terms and conditions of this
Agreement, Bank hereby agrees to make advances to Borrower from time to time up
to and including February 1, 2004, not to exceed at any time the aggregate
principal amount of Fifteen Million Dollars ($15,000,000.00) ("Line of Credit"),
the proceeds of which shall be used to finance Borrower's working capital
requirements. Borrower's obligation to repay advances under the Line of Credit
shall be evidenced by a promissory note substantially in the form of EXHIBIT A
attached hereto ("Line of Credit Note"), all terms of which are incorporated
herein by this reference.

        (b)     Letter of Credit Subfeature. As a subfeature under the Line of
Credit, Bank agrees from time to time during the term thereof to issue or cause
an affiliate to issue commercial and standby letters of credit for the account
of Borrower to finance general purpose (each, a "Letter of Credit" and
collectively, "Letters of Credit"); provided however, that the aggregate undrawn
amount of all outstanding Letters of Credit shall not at any time exceed Five
Million Dollars ($5,000,000.00). The form and substance of each Letter of Credit
shall be subject to approval by Bank, in its sole discretion. Each Letter of
Credit shall be issued for a term not to exceed three hundred sixty-five (365)
days, as designated by Borrower; provided however, that no Letter of Credit
shall have an expiration date subsequent to the maturity date of the Line of
Credit. The undrawn amount of all Letters of Credit shall be reserved under the
Line of Credit and shall not be available for borrowings thereunder. Each Letter
of Credit shall be subject to the additional terms and conditions of the Letter
of Credit agreements, applications and any related documents required by Bank in
connection with the issuance thereof. Each drawing paid under a Letter of Credit
shall be deemed an advance under the Line of Credit and shall be repaid by
Borrower in accordance with the terms and conditions of this Agreement
applicable to such advances; provided however, that if advances under the Line
of Credit are not available, for any reason, at the time any drawing is paid,
then Borrower shall immediately pay to Bank the full amount drawn, together with
interest thereon from the date such drawing is paid to the date such amount is
fully repaid by Borrower, at the rate of interest applicable to advances under
the Line of Credit. In such event Borrower agrees that Bank, in its sole
discretion, may debit any account maintained by Borrower with Bank for the
amount of any such drawing.

<PAGE>
        (c)     Borrowing and Repayment. Borrower may from time to time during
the term of the Line of Credit borrow, partially or wholly repay its outstanding
borrowings, and reborrow, subject to all of the limitations, terms and
conditions contained herein or in the Line of Credit Note; provided however,
that the total outstanding borrowings under the Line of Credit shall not at any
time exceed the maximum principal amount available thereunder, as set forth
above.

        SECTION 1.2. FOREIGN EXCHANGE FACILITY.

        (a)     Foreign Exchange Facility. Subject to the terms and conditions
of this Agreement, Bank hereby agrees to make available to Borrower a facility
(the "Foreign Exchange Facility") under which Bank, from time to time up to and
including February 1, 2004, will enter into foreign exchange contracts for the
account of Borrower for the purchase and/or sale by Borrower in United States
dollars of Euro, Pound, Japanese yen, Australian dollars, Rand, Canadian
dollars, Mexican Peso, Singapore dollars and Brazilian real; provided however,
that the maximum amount of all outstanding foreign exchange contracts shall not
at any time exceed an aggregate of Twenty Million United States Dollars
(US$20,000,000.00). No foreign exchange contract shall be executed for a term
which extends beyond February 1, 2004. Borrower shall have a "Delivery Limit"
under the Foreign Exchange Facility not to exceed at any time the aggregate
principal amount of Four Million United States Dollars (US$4,000,000.00), which
Delivery Limit reflects the maximum principal amount of Borrower's foreign
exchange contracts which may mature during any two (2) day period. All foreign
exchange transactions shall be subject to the additional terms of a Foreign
Exchange Agreement, substantially in the form of EXHIBIT B attached hereto
("Foreign Exchange Agreement"), all terms of which are incorporated herein by
this reference.

        (b)     Settlement. Each foreign exchange contract under the Foreign
Exchange Facility shall be settled on its maturity date by Bank's debit to any
deposit account maintained by Borrower with Bank.

        SECTION 1.3. INTEREST/FEES.

        (a)     Interest. The outstanding principal balance of the Line of
Credit shall bear interest, and the amount of each drawing paid under any Letter
of Credit shall bear interest from the date such drawing is paid to the date
such amount is fully repaid by Borrower, at the rate of interest set forth in
the Line of Credit Note.

        (b)     Computation and Payment. Interest shall be computed on the basis
of a 360-day year, actual days elapsed. Interest shall be payable at the times
and place set forth in each promissory note or other instrument or document
required hereby.

        (c)     Commitment Fee. Borrower shall pay to Bank a non-refundable
commitment fee for the Line of Credit equal to Seven Thousand Five Hundred
Dollars ($7,500.00), which fee shall be due and payable in full upon execution
of this Agreement.

        (d)     Commercial Letter of Credit Fees. Borrower shall pay to Bank
fees upon the issuance of each Commercial Letter of Credit, upon the payment or
negotiation of each drawing under any Commercial Letter of Credit and upon the
occurrence of any other activity with respect to any Commercial Letter of Credit
(including without limitation, the transfer, amendment or cancellation of any
Commercial Letter of Credit) determined in accordance with Bank's standard fees
and charges then in effect for such activity.

<PAGE>
        (e)     Standby Letter of Credit Fees. Borrower shall pay to Bank (i)
fees upon the issuance of each Standby Letter of Credit equal to one percent
(1%) per annum (computed on the basis of a 360-day year, actual days elapsed) of
the face amount thereof, and (ii) fees upon the payment or negotiation of each
drawing under any Standby Letter of Credit and fees upon the occurrence of any

        SECTION 1.4. COLLECTION OF PAYMENTS. Borrower authorizes Bank to collect
all interest and fees due under the Line of Credit by charging Borrower's
deposit account number 4945-010403 with Bank, or any other deposit account
maintained by Borrower with Bank, for the full amount thereof. Should there be
insufficient funds in any such deposit account to pay all such sums when due,
the full amount of such deficiency shall be immediately due and payable by
Borrower.

including without limitation the right to resort to any or all security for any
credit subject hereto and to exercise any or all of the rights of a beneficiary
or secured party pursuant to applicable law. All rights, powers and remedies of
Bank may be exercised at any time by Bank and from time to time after the
occurrence of an Event of Default, are cumulative and not exclusive, and shall
be in addition to any other rights, powers or remedies provided by law or
equity.

                                  MISCELLANEOUS

        SECTION 7.1. NO WAIVER. No delay, failure or discontinuance of Bank in

single or partial exercise of any such right, power or remedy preclude, waive or
otherwise affect any other or further exercise thereof or the exercise of any
other right, power or remedy. Any waiver, permit, consent or approval of any
kind by Bank of any breach of or default under any of the Loan Documents must be
in writing and shall be effective only to the extent set forth in such writing.

entity.

        SECTION 7.4. SUCCESSORS, ASSIGNMENT. This Agreement shall be binding
upon and inure to the benefit of the heirs, executors, administrators, legal
representatives, successors and assigns of the parties; provided however, that
Borrower may not assign or transfer its interest hereunder without Bank's prior

        SECTION 7.8. SEVERABILITY OF PROVISIONS. If any provision of this

shall be ineffective only to the extent of such prohibition or invalidity
without invalidating the remainder of such provision or any remaining provisions
of this Agreement.

        SECTION 7.9. COUNTERPARTS. This Agreement may be executed in any number
of counterparts, each of which when executed and delivered shall be deemed to be

        SECTION 7.10. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of California.

        SECTION 7.11. ARBITRATION.

        (a)     Arbitration. The parties hereto agree, upon demand by any party,
to submit to binding arbitration all claims, disputes and controversies between
or among them (and their respective employees, officers, directors, attorneys,
and other agents), whether in tort, contract or otherwise arising out of or
relating to in any way (i) the loan and related Loan Documents which are the
subject of this Agreement and its negotiation, execution, collateralization,
administration, repayment, modification, extension, substitution, formation,
inducement, enforcement, default or termination; or (ii) requests for additional
credit.

<PAGE>
        (b)     Governing Rules. Any arbitration proceeding will (i) proceed in
a location in California selected by the American Arbitration Association
("AAA"); (ii) be governed by the Federal Arbitration Act (Title 9 of the United
States Code), notwithstanding any conflicting choice of law provision in any of
the documents between the parties; and (iii) be conducted by the AAA, or such
other administrator as the parties shall mutually agree upon, in accordance with
the AAA's commercial dispute resolution procedures, unless the claim or
counterclaim is at least $1,000,000.00 exclusive of claimed interest,
arbitration fees and costs in which case the arbitration shall be conducted in
accordance with the AAA's optional procedures for large, complex commercial
disputes (the commercial dispute resolution procedures or the optional
procedures for large, complex commercial disputes to be referred to, as
applicable, as the "Rules"). If there is any inconsistency between the terms
hereof and the Rules, the terms and procedures set forth herein shall control.
Any party who fails or refuses to submit to arbitration following a demand by
any other party shall bear all costs and expenses incurred by such other party
in compelling arbitration of any dispute. Nothing contained herein shall be
deemed to be a waiver by any party that is a bank of the protections afforded to
it under 12 U.S.C. Section 91 or any similar applicable state law.

        (c)     No Waiver of Provisional Remedies, Self-Help and Foreclosure.
The arbitration requirement does not limit the right of any party to (i)
foreclose against real or personal property collateral; (ii) exercise self-help
remedies relating to collateral or proceeds of collateral such as setoff or
repossession; or (iii) obtain provisional or ancillary remedies such as
replevin, injunctive relief, attachment or the appointment of a receiver, before
during or after the pendency of any arbitration proceeding. This exclusion does
not constitute a waiver of the right or obligation of any party to submit any
dispute to arbitration or reference hereunder, including those arising from the
exercise of the actions detailed in sections (i), (ii) and (iii) of this
paragraph.

        (d)     Arbitrator Qualifications and Powers. Any arbitration proceeding
in which the amount in controversy is $5,000,000.00 or less will be decided by a
single arbitrator selected according to the Rules, and who shall not render an
award of greater than $5,000,000.00. Any dispute in which the amount in
controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel
of three arbitrators; provided however, that all three arbitrators must actively
participate in all hearings and deliberations. The arbitrator will be a neutral
attorney licensed in the State of California or a neutral retired judge of the
state or federal judiciary of California, in either case with a minimum of ten
years experience in the substantive law applicable to the subject matter of the
dispute to be arbitrated. The arbitrator will determine whether or not an issue
is arbitratable and will give effect to the statutes of limitation in
determining any claim. In any arbitration proceeding the arbitrator will decide
(by documents only or with a hearing at the arbitrator's discretion) any
pre-hearing motions which are similar to motions to dismiss for failure to state
a claim or motions for summary adjudication. The arbitrator shall resolve all
disputes in accordance with the substantive law of California and may grant any
remedy or relief that a court of such state could order or grant within the
scope hereof and such ancillary relief as is necessary to make effective any
award. The arbitrator shall also have the power to award recovery of all costs
and fees, to impose sanctions and to take such other action as the arbitrator
deems necessary to the same extent a judge could pursuant to the Federal Rules
of Civil Procedure, the California Rules of Civil Procedure or other applicable
law. Judgment upon the award rendered by the arbitrator may be entered in any
court having jurisdiction. The institution and maintenance of an action for
judicial relief or pursuit of a provisional or ancillary remedy shall not
constitute a waiver of the right of any party, including the plaintiff, to
submit the controversy or claim to arbitration if any other party contests such
action for judicial relief.

<PAGE>
        (e)     Discovery. In any arbitration proceeding discovery will be
permitted in accordance with the Rules. All discovery shall be expressly limited
to matters directly relevant to the dispute being arbitrated and must be
completed no later than 20 days before the hearing date and within 180 days of
the filing of the dispute with the AAA. Any requests for an extension of the
discovery periods, or any discovery disputes, will be subject to final
determination by the arbitrator upon a showing that the request for discovery is
essential for the party's presentation and that no alternative means for
obtaining information is available.

        (f)     Class Proceedings and Consolidations. The resolution of any
dispute arising pursuant to the terms of this Agreement shall be determined by a
separate arbitration proceeding and such dispute shall not be consolidated with
other disputes or included in any class proceeding.

        (g)     Payment Of Arbitration Costs And Fees. The arbitrator shall
award all costs and expenses of the arbitration proceeding.

        (h)     Real Property Collateral; Judicial Reference. Notwithstanding
anything herein to the contrary, no dispute shall be submitted to arbitration if
the dispute concerns indebtedness secured directly or indirectly, in whole or in
part, by any real property unless (i) the holder of the mortgage, lien or
security interest specifically elects in writing to proceed with the
arbitration, or (ii) all parties to the arbitration waive any rights or benefits
that might accrue to them by virtue of the single action rule statute of
California, thereby agreeing that all indebtedness and obligations of the
parties, and all mortgages, liens and security interests securing such
indebtedness and obligations, shall remain fully valid and enforceable. If any
such dispute is not submitted to arbitration, the dispute shall be referred to a
referee in accordance with California Code of Civil Procedure Section 638 et
seq., and this general reference agreement is intended to be specifically
enforceable in accordance with said Section 638. A referee with the
qualifications required herein for arbitrators shall be selected pursuant to the
AAA's selection procedures. Judgment upon the decision rendered by a referee
shall be entered in the court in which such proceeding was commenced in
accordance with California Code of Civil Procedure Sections 644 and 645.

        (i)     Miscellaneous. To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceeding within 180 days of the filing of the dispute with the
AAA. No arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business or by applicable law or
regulation. If more than one agreement for arbitration by or between the parties
potentially applies to a dispute, the arbitration provision most directly
related to the Loan Documents or the subject matter of the dispute shall
control. This arbitration provision shall survive termination, amendment or
expiration of any of the Loan Documents or any relationship between the parties.

                          REVOLVING LINE OF CREDIT NOTE

$15,000,000.00                                              Carlsbad, California
                                                                November 1, 2002

        FOR VALUE RECEIVED, the undersigned FAIR, ISAAC AND COMPANY,
INCORPORATED ("Borrower") promises to pay to the order of WELLS FARGO BANK,
NATIONAL ASSOCIATION ("Bank") at its office at Carlsbad LPO, 5857 Owens Avenue,
Suite 106, Carlsbad, California, or at such other place as the holder hereof may
designate, in lawful money of the United States of America and in immediately
available funds, the principal sum of Fifteen Million Dollars ($15,000,000.00),
or so much thereof as may be advanced and be outstanding, with interest thereon,
to be computed on each advance from the date of its disbursement as set forth
herein.

DEFINITIONS:

        As used herein, the following terms shall have the meanings set forth
after each, and any other term defined in this Note shall have the meaning set
forth at the place defined:

        (a) "Business Day" means any day except a Saturday, Sunday or any other
day on which commercial banks in California are authorized or required by law to
close.

        (b) "Fixed Rate Term" means a period commencing on a Business Day and
continuing for one (1), two (2), three (3) or six (6) months, as designated by
Borrower, during which all or a portion of the outstanding principal balance of
this Note bears interest determined in relation to LIBOR; provided however, that
no Fixed Rate Term may be selected for a principal amount less than Two Hundred
Fifty Thousand Dollars ($250,000.00); and provided further, that no Fixed Rate
Term shall extend beyond the scheduled maturity date hereof. If any Fixed Rate
Term would end on a day which is not a Business Day, then such Fixed Rate Term
shall be extended to the next succeeding Business Day.

        (c) "LIBOR" means the rate per annum (rounded upward, if necessary, to
the nearest whole 1/8 of 1%) and determined pursuant to the following formula:

                      LIBOR =               Base LIBOR
                               --------------------------------------
                                  100% - LIBOR Reserve Percentage

               (i) "Base LIBOR" means the rate per annum for United States
dollar deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the
understanding that such rate is quoted by Bank for the purpose of calculating
effective rates of interest for loans making reference thereto, on the first day
of a Fixed Rate Term for delivery of funds on said date for a period of time
approximately equal to the number of days in such Fixed Rate Term and in an
amount approximately equal to the principal amount to which such Fixed Rate Term
applies. Borrower understands and agrees that Bank may base its quotation of the
Inter-Bank Market Offered Rate upon such offers or other market indicators of
the Inter-Bank Market as Bank in its discretion deems appropriate including, but
not limited to, the rate offered for U.S. dollar deposits on the London
Inter-Bank Market.

                                      -1-
<PAGE>

               (ii) "LIBOR Reserve Percentage" means the reserve percentage
prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for "Eurocurrency Liabilities" (as defined in Regulation D of the
Federal Reserve Board, as amended), adjusted by Bank for expected changes in
such reserve percentage during the applicable Fixed Rate Term.

        (d) "Prime Rate" means at any time the rate of interest most recently
announced within Bank at its principal office as its Prime Rate, with the
understanding that the Prime Rate is one of Bank's base rates and serves as the
basis upon which effective rates of interest are calculated for those loans
making reference thereto, and is evidenced by the recording thereof after its
announcement in such internal publication or publications as Bank may designate.

INTEREST:

        (a) Interest. The outstanding principal balance of this Note shall bear
interest (computed on the basis of a 360-day year, actual days elapsed) either
(i) at a fluctuating rate per annum equal to the Prime Rate in effect from time
to time, or (ii) at a fixed rate per annum determined by Bank to be one and one
quarter percent (1.25%) above LIBOR in effect on the first day of the applicable
Fixed Rate Term. When interest is determined in relation to the Prime Rate, each
change in the rate of interest hereunder shall become effective on the date each
Prime Rate change is announced within Bank. With respect to each LIBOR selection
hereunder, Bank is hereby authorized to note the date, principal amount,
interest rate and Fixed Rate Term applicable thereto and any payments made
thereon on Bank's books and records (either manually or by electronic entry)
and/or on any schedule attached to this Note, which notations shall be prima
facie evidence of the accuracy of the information noted.

        (b) Selection of Interest Rate Options. At any time any portion of this
Note bears interest determined in relation to LIBOR, it may be continued by
Borrower at the end of the Fixed Rate Term applicable thereto so that all or a
portion thereof bears interest determined in relation to the Prime Rate or to
LIBOR for a new Fixed Rate Term designated by Borrower. At any time any portion
of this Note bears interest determined in relation to the Prime Rate, Borrower
may convert all or a portion thereof so that it bears interest determined in
relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as
Borrower requests an advance hereunder or wishes to select a LIBOR option for
all or a portion of the outstanding principal balance hereof, and at the end of
each Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the
interest rate option selected by Borrower; (ii) the principal amount subject
thereto; and (iii) for each LIBOR selection, the length of the applicable Fixed
Rate Term. Any such notice may be given by telephone (or such other electronic
method as Bank may permit) so long as, with respect to each LIBOR selection, (A)
if requested by Bank, Borrower provides to Bank written confirmation thereof not
later than three (3) Business Days after such notice is given, and (B) such
notice is given to Bank prior to 10:00 a.m. on the first day of the Fixed Rate
Term, or at a later time during any Business Day if Bank, at it's sole option
but without obligation to do so, accepts Borrower's notice and quotes a fixed
rate to Borrower. If Borrower does not immediately accept a fixed rate when
quoted by Bank, the quoted rate shall expire and any subsequent LIBOR request
from Borrower shall be subject to a redetermination by Bank of the applicable
fixed rate. If no specific designation of interest is made at the time any
advance is requested hereunder or at the end of any Fixed Rate Term, Borrower
shall be deemed to have made a Prime Rate interest selection for such advance or
the principal amount to which such Fixed Rate Term applied.

                                      -2-
<PAGE>

        (c) Taxes and Regulatory Costs. Borrower shall pay to Bank immediately
upon demand, in addition to any other amounts due or to become due hereunder,
any and all (i) withholdings, interest equalization taxes, stamp taxes or other
taxes (except income and franchise taxes) imposed by any domestic or foreign
governmental authority and related in any manner to LIBOR, and (ii) future,
supplemental, emergency or other changes in the LIBOR Reserve Percentage,
assessment rates imposed by the Federal Deposit Insurance Corporation, or
similar requirements or costs imposed by any domestic or foreign governmental
authority or resulting from compliance by Bank with any request or directive
(whether or not having the force of law) from any central bank or other
governmental authority and related in any manner to LIBOR to the extent they are
not included in the calculation of LIBOR. In determining which of the foregoing
are attributable to any LIBOR option available to Borrower hereunder, any
reasonable allocation made by Bank among its operations shall be conclusive and
binding upon Borrower.

        (d) Payment of Interest. Interest accrued on this Note shall be payable
on the last day of each month, commencing November 30, 2002.

        (e) Default Interest. From and after the maturity date of this Note, or
such earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of this Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed) equal to four percent (4%) above
the rate of interest from time to time applicable to this Note.

BORROWING AND REPAYMENT:

        (a) Borrowing and Repayment. Borrower may from time to time during the
term of this Note borrow, partially or wholly repay its outstanding borrowings,
and reborrow, subject to all of the limitations, terms and conditions of this
Note and of any document executed in connection with or governing this Note;
provided however, that the total outstanding borrowings under this Note shall
not at any time exceed the principal amount stated above. The unpaid principal
balance of this obligation at any time shall be the total amounts advanced
hereunder by the holder hereof less the amount of principal payments made hereon
by or for any Borrower, which balance may be endorsed hereon from time to time
by the holder. The outstanding principal balance of this Note shall be due and
payable in full on February 1, 2004.

        (b) Advances. Advances hereunder, to the total amount of the principal
sum stated above, may be made by the holder at the oral or written request of
(i) _____________________ or ________________________, any one acting alone, who
are authorized to request advances and direct the disposition of any advances
until written notice of the revocation of such authority is received by the
holder at the office designated above, or (ii) any person, with respect to
advances deposited to the credit of any deposit account of any Borrower, which
advances, when so deposited, shall be conclusively presumed to have been made to
or for the benefit of each Borrower regardless of the fact that persons other
than those authorized to request advances may have authority to draw against
such account. The holder shall have no obligation to determine whether any
person requesting an advance is or has been authorized by any Borrower.

        (c) Application of Payments. Each payment made on this Note shall be
credited first, to any interest then due and second, to the outstanding
principal balance hereof. All payments credited to principal shall be applied
first, to the outstanding principal balance of this Note which bears interest
determined in relation to the Prime Rate, if any, and second, to the

                                      -3-
<PAGE>

outstanding principal balance of this Note which bears interest determined in
relation to LIBOR, with such payments applied to the oldest Fixed Rate Term
first.

PREPAYMENT:

        (a) Prime Rate. Borrower may prepay principal on any portion of this
Note which bears interest determined in relation to the Prime Rate at any time,
in any amount and without penalty.

        (b) LIBOR. Borrower may prepay principal on any portion of this Note
which bears interest determined in relation to LIBOR at any time and in the
minimum amount of Two Hundred Fifty Thousand Dollars ($250,000.00); provided
however, that if the outstanding principal balance of such portion of this Note
is less than said amount, the minimum prepayment amount shall be the entire
outstanding principal balance thereof. In consideration of Bank providing this
prepayment option to Borrower, or if any such portion of this Note shall become
due and payable at any time prior to the last day of the Fixed Rate Term
applicable thereto by acceleration or otherwise, Borrower shall pay to Bank
immediately upon demand a fee which is the sum of the discounted monthly
differences for each month from the month of prepayment through the month in
which such Fixed Rate Term matures, calculated as follows for each such month:

       (i)     Determine the amount of interest which would have accrued each
               month on the amount prepaid at the interest rate applicable to
               such amount had it remained outstanding until the last day of the
               Fixed Rate Term applicable thereto.

      (ii)     Subtract from the amount determined in (i) above the amount of
               interest which would have accrued for the same month on the
               amount prepaid for the remaining term of such Fixed Rate Term at
               LIBOR in effect on the date of prepayment for new loans made for
               such term and in a principal amount equal to the amount prepaid.

     (iii)     If the result obtained in (ii) for any month is greater than
               zero, discount that difference by LIBOR used in (ii) above.

Each Borrower acknowledges that prepayment of such amount may result in Bank
incurring additional costs, expenses and/or liabilities, and that it is
difficult to ascertain the full extent of such costs, expenses and/or
liabilities. Each Borrower, therefore, agrees to pay the above-described
prepayment fee and agrees that said amount represents a reasonable estimate of
the prepayment costs, expenses and/or liabilities of Bank. If Borrower fails to
pay any prepayment fee when due, the amount of such prepayment fee shall
thereafter bear interest until paid at a rate per annum two percent (2%) above
the Prime Rate in effect from time to time (computed on the basis of a 360-day
year, actual days elapsed). Each change in the rate of interest on any such past
due prepayment fee shall become effective on the date each Prime Rate change is
announced within Bank.

EVENTS OF DEFAULT:

        This Note is made pursuant to and is subject to the terms and conditions
of that certain Credit Agreement between Borrower and Bank dated as of November
1, 2002, as amended from time to time (the "Credit Agreement"). Any default in
the payment or performance of any

                                      -4-
<PAGE>

obligation under this Note, or any defined event of default under the Credit
Agreement, shall constitute an "Event of Default" under this Note.

MISCELLANEOUS:

        (a) Remedies. Upon the occurrence of any Event of Default, the holder of
this Note, at the holder's option, may declare all sums of principal and
interest outstanding hereunder to be immediately due and payable without
presentment, demand, notice of nonperformance, notice of protest, protest or
notice of dishonor, all of which are expressly waived by each Borrower, and the
obligation, if any, of the holder to extend any further credit hereunder shall
immediately cease and terminate. Each Borrower shall pay to the holder
immediately upon demand the full amount of all payments, advances, charges,
costs and expenses, including reasonable attorneys' fees (to include outside
counsel fees and all allocated costs of the holder's in-house counsel), expended
or incurred by the holder in connection with the enforcement of the holder's
rights and/or the collection of any amounts which become due to the holder under
this Note, and the prosecution or defense of any action in any way related to
this Note, including without limitation, any action for declaratory relief,
whether incurred at the trial or appellate level, in an arbitration proceeding
or otherwise, and including any of the foregoing incurred in connection with any
bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Bank or any other person) relating to any
Borrower or any other person or entity.

        (b) Obligations Joint and Several. Should more than one person or entity
sign this Note as a Borrower, the obligations of each such Borrower shall be
joint and several.

               RE:  Foreign Exchange Agreement

Ladies and Gentlemen:

        You, the customer to whom this letter agreement (the "Agreement") is
addressed, may from time to time request that we, WELLS FARGO BANK, NATIONAL
ASSOCIATION, or, if we are not Wells Fargo Bank, National Association ("Wells
Fargo"), Wells Fargo acting as our agent, enter into foreign exchange contracts
with you (each, a "Contract" and collectively, "Contracts") for spot or forward
delivery of foreign currencies that you want to purchase or sell. Upon receipt
of each such request, we, or Wells Fargo acting as our agent, will decide
whether to enter into a Contract with you. This Agreement sets forth the terms
and conditions governing the Contracts and the transactions contemplated thereby
(each a "Transaction"). You understand and agree that if we are not Wells Fargo,
we may, but are not obligated to, use Wells Fargo as our agent to enter into
Contracts with you in our name or in Wells Fargo's name. You authorize us to use
Wells Fargo as our agent to enter into Contracts with you and to perform any of
our obligations or exercise any of our rights under this Agreement or any
Contract. If we use Wells Fargo as our agent, (a) Wells Fargo will be our agent
having obligations only to us and not to you, (b) the Contracts you enter into
through Wells Fargo will be considered Contracts entered into by us pursuant to
this Agreement, unless any such Contract clearly indicates otherwise, (c) any of
our obligations performed or any of our rights exercised pursuant to, or in
connection with, this Agreement or any Contract by Wells Fargo in our name or in
Wells Fargo's name shall be deemed obligations performed or rights exercised by
us pursuant to, or in connection with, this Agreement or such Contract, and (d)
any collateral heretofore, now or at any time hereafter granted or pledged by
you to us as security for any credit extended to you will also secure all your
obligations to us under or in connection with this Agreement and the Contracts.

        1. REQUESTS TO ENTER INTO, AMEND OR CANCEL CONTRACTS. All requests to us
to enter into, amend or cancel Contracts must be made by telephone, facsimile
transmission ("Fax"), or electronic mail ("E-Mail"). We have no obligation to,
and we will determine in our sole discretion whether or not to, enter into,
amend or cancel any Contract. If we do enter into, amend or cancel any Contract
at your request, we will not be obligated to enter into, amend or cancel any
other Contract. Requests to enter into Contracts must specify (a) whether the
request is to purchase or sell foreign currency, (b) the type of foreign
currency, (c) the amount of foreign currency, and (d) the value date for the
Contract (the "Settlement Date").

<PAGE>

Fair, Isaac and Company, Incorporated

Page 2

Requests to amend or cancel Contracts must identify the number of the Contract
to be amended or cancelled. In addition to the requirements above, each Fax
request to enter into, amend or cancel a Contract must clearly indicate the name
of the sender and be signed and dated, and each E-Mail request to enter into,
amend or cancel a Contract must clearly indicate the name of the sender and be
dated. Each request for a Contract for spot delivery of foreign currency also
must specify where and how the currency is to be delivered. With respect to each
request for a Contract for forward delivery of foreign currency, you must also
send us settlement instructions by telephone, Fax or E-Mail no later than two
Business Days (with the term "Business Day" meaning a day, other than a
Saturday, Sunday or public holiday, on which we and you are open to conduct
Transactions) before the Settlement Date informing us where and how the currency
is to be delivered. Any settlement instructions sent by Fax must clearly
indicate the name of the sender and be signed and dated, and any settlement
instructions sent by E-Mail must clearly indicate the name of the sender and be
dated. Each request to enter into, amend or cancel a Contract and all settlement
instructions must be directed to your primary foreign exchange advisor with us
or an alternate advisor designated by us. You authorize us to rely on all
information and directions contained in each such request and settlement
instruction. If a settlement instruction for a Contract describes (i) by account
name and number the account to which currency is to be delivered by us upon
settlement and the account name and number do not match, you understand that we
will make payment on the basis of the account number even if it is not the
account number of the person or entity named by you in the settlement
instructions, or (ii) by name and identification number or code a financial
institution to which such currency is to be delivered and the name and
identification number or code do not match, you understand that we may make
payment on the basis of such identification number or code even if such number
or code is not the identification number or code of the financial institution
named by you in the settlement instructions. You understand and agree that if
settlement of a Contract is to be made by "payment against delivery" (A) if you
are to pay United States dollars to us under the Contract, this payment must be
made by you one or two days (as notified to you) before the Settlement Date, and
we will not deliver the foreign currency to you on the Settlement Date if you do
not comply with this requirement, and (B) if you are to deliver foreign currency
to us and we are to pay United States dollars to you under the Contract, we will
pay you such dollars on the Settlement Date only if the bank to which you are to
pay the foreign currency confirms to us that it has received the full amount of
such foreign currency.

        2. CONFIRMATIONS OF CONTRACTS AND AMENDMENTS TO CONTRACTS. Promptly
after we accept a request to enter into or amend a Contract, we will confirm the
Contract or amendment by telephone (which confirmations sometimes will be
re-confirmed by mail, Fax or E-Mail), mail, Fax or E-Mail. We will not be bound
by any Contract or amendment that is not so confirmed by us. Promptly after you
receive our confirmation of a Contract or amendment you will review it
carefully. If such confirmation accurately reflects the terms of the Contract or
amendment you requested and we and you agreed upon, (a) if it is sent by mail or
Fax, sign it and return it to us by mail, Fax, or attached to an E-Mail, or (b)
if it is sent by telephone, promptly sign any written re-confirmation you
receive and return it to us by mail, Fax, or attached to an E-Mail, or (c) if it
is sent by E-Mail, promptly print the E-Mail, sign it, and return it to us by
mail, Fax, or attached to an E-Mail. If such confirmation does not accurately
reflect the terms of the Contract or amendment we and you agreed upon or you
intended, notify us by telephone of such inaccuracy. Each confirmation you sign
and return to us should be sent to us at the address or Fax number indicated on
such confirmation. Each notification of errors in a confirmation must be sent to
us at the telephone number indicated on such confirmation. Until we receive a
notification that a confirmation does not accurately reflect the terms of a
Contract or amendment we and you agreed upon (and our records confirm that this
is true), (i) the first or

<PAGE>

Fair, Isaac and Company, Incorporated
November 1, 2002
Page 3

only confirmation of a Contract or amendment will be deemed to contain the
definitive terms of such Contract or amendment, and (ii) we will be authorized
to act on the Contract or amendment as reflected in such confirmation, and
unless we receive such notification from you before we act on or comply with the
terms of such Contract or amendment, you will, except as provided otherwise in
the Limitation of Liability and Indemnity section of this Agreement, indemnify
and reimburse us for, and hold us harmless from and against, all of our Losses
which arise directly or indirectly as a result of, or which are in any way
connected with, our acting on or complying with the terms of the Contract or
amendment as reflected in such confirmation. The term "Losses" as used in this
Agreement will mean all losses, liabilities, claims, damages, obligations,
penalties, actions, judgments, suits, costs and expenses, of any kind
whatsoever, including, without limitation, attorneys' fees and other legal costs
and expenses (which attorneys' fees will include outside counsel fees and all
allocated costs of in-house counsel), paid, suffered or incurred by, or imposed
upon, you or us as the context indicates.

        3. VERIFYING CONFIRMATIONS, REQUESTS TO ENTER INTO, AMEND OR CANCEL
CONTRACTS, AND SETTLEMENT INSTRUCTIONS. We will verify each request to enter
into or amend or cancel a Contract, each instruction for the settlement of a
Contract, and each confirmation you return to us by determining if the name used
by the person requesting the Contract or amendment or cancellation of a
Contract, giving us settlement instructions, or signing the confirmation is the
name of one of the persons you designate to us in writing as being authorized by
you to make such requests and instructions and to sign such confirmations. Other
than as provided in the preceding sentence, we have no obligation to confirm in
any way the identity of any person making a request to enter into or amend or
cancel a Contract, giving an instruction for the settlement of a Contract, or
signing a confirmation of a Contract or an amendment. We will not be required to
verify that (a) the entries on a document sent to us in any way are authentic
entries, (b) the signatures on any such document are authentic signatures, or
(c) the persons actually signing such document are duly authorized to contract
for you in connection with the purposes of the document. The information,
directions or instructions we receive in documents which indicate that they have
been sent from you or which are on your letterhead, other than requests to enter
into or amend or cancel Contracts or settlement instructions for Contracts or
confirmations of Contracts, will be binding on you even if such documents are
not signed or are not properly authorized by you. You agree to be bound by each
request to enter into, amend or cancel a Contract, each instruction for the
settlement of a Contract, and each confirmation of a Contract or amendment if
such request, instruction or confirmation was authorized or transmitted by you,
or made in your name and accepted by us in good faith and in compliance with the
procedures in this Section, even if such request, instruction or confirmation
was not properly authorized by you. Except as provided otherwise in the
Limitation of Liability and Indemnity section of this Agreement, we shall have
no liability for any of your Losses, and you will indemnify us for all our
Losses, which arise directly or indirectly as a result of, or are in any way
connected with, (i) any request to enter into or amend or cancel a Contract, any
instruction for the settlement of a Contract, and any confirmation of a Contract
or amendment being made by Fax or E-Mail, or (ii) any breach of your security
procedures in connection with any request to enter into or amend or cancel a
Contract, any instruction for the settlement of a Contract, and the signing of
any confirmation of a Contract or amendment. Any actions we take to detect
erroneous requests to enter into or amend or cancel Contracts or erroneous
instructions for the settlement of Contracts, or any actions we take beyond
those described above in an attempt to detect unauthorized requests or
instructions or confirmations, will be taken at our sole discretion. No matter
how many times we take such actions they will not become part of our standard
procedures for attempting to detect erroneous or unauthorized

<PAGE>

Fair, Isaac and Company, Incorporated
November 1, 2002
Page 4

requests or instructions or confirmations, and we will not in any situation be
liable for failing to take or to correctly perform such actions.

        4. REPRESENTATIONS AND WARRANTIES. We make no express or implied
representations or warranties with respect to the services we are to provide to
you under this Agreement or any Contract, other than those representations or
warranties expressly stated in this Agreement. Each request by you that we enter
into or amend a Contract shall be deemed a representation and warranty by you
that the terms of the Contract or such amendment do not, and your compliance
with such terms will not, violate any laws and regulations applicable to you,
including, without limitation, those affecting your purchase or sale of the
foreign currency covered by the Contract, and that no Event of Default (as
defined in the Events of Default and Remedies section of this Agreement) has
occurred and is continuing.

        5. NO INVESTMENT ADVICE; RISK OF MARKET FLUCTUATIONS. You understand
that we are not an investment advisor. We do not give, and we hereby disclaim,
all investment advice with respect to any Contract or any amendment of a
Contract. You bear the sole risk of any and all market fluctuations in any
currency traded pursuant to the terms of this Agreement or any Contract.

        6. EVENTS OF DEFAULT AND REMEDIES. We may cancel any Contract and
liquidate our position in the currency of such Contract if performance of the
Contract by you or us becomes unlawful as a result of the adoption of, or any
change in, any applicable law after the date on which the Contract is entered
into, or as a result of the promulgation of or any change in, or in the
interpretation by any court or tribunal or regulatory authority with competent
jurisdiction of, any applicable law after such date. Upon the occurrence and at
any time during the continuance of any of the following events (each, an "Event
of Default"), we may also cancel any or all the outstanding Contracts and
liquidate our position in the currency of such Contracts and setoff against any
of your cash, deposit accounts, securities, securities accounts or other
property we hold or any obligation we have to you to recover any amounts you owe
to us as a result of, or in connection with, such cancellation or liquidation:
(a) you fail to give us settlement instructions as provided in this Agreement;
(b) you fail for any other reason to settle a Contract on its Settlement Date;
(c) you fail to perform any of your agreements or obligations under this
Agreement or any Contract; (d) any representation or warranty made by you to us
under this Agreement or any Contract is incorrect or misleading in any material
respect when made or repeated or deemed to have been made or repeated; (e) a
default, event of default or other similar condition or event (however
described) occurs under one or more agreements or instruments relating to any of
your obligations (whether present or future, contingent or otherwise, as
principal or surety or otherwise) in respect of borrowed money ("Indebtedness")
which has resulted in such Indebtedness becoming, or becoming capable at such
time of being declared, due and payable under such agreements or instruments,
before it would otherwise have been due and payable; (f) you (i) dissolve or
liquidate, (ii) are not generally paying your debts as they become due, (iii)
become insolvent, however such insolvency may be evidenced, or (iv) make any
general assignment for the benefit of creditors; (g) a petition is filed by or
against you seeking your liquidation or reorganization under the Bankruptcy
Reform Act, Title 11 of the United States Code, as amended or recodified from
time to time, or a similar action is brought by or against you under any
federal, state or foreign law; (h) a proceeding is instituted by or against you
for any relief under any bankruptcy, insolvency or other law relating to the
relief of debtors, reorganization, readjustment or extension of indebtedness or
composition with creditors; (i) a custodian or a receiver is appointed for, or a
writ or order of attachment, execution or garnishment

<PAGE>

Fair, Isaac and Company, Incorporated

Page 5

is issued, levied or made against, any of your property or assets; (j) an
application is made by any of your judgment creditors for an order directing us
to pay over money that we hold from you or to deliver other of your property;
(k) any government authority or any court takes possession of any substantial
part of your property or assets or assumes control over your affairs, or (l) we
in our sole discretion make a commercially reasonable determination that such
cancellation is necessary to protect us.

        7. LOSSES RESULTING FROM CANCELLATIONS OR EXTENSIONS OF CONTRACTS. If
you request that we cancel a Contract or amend a Contract by extending its term
and we, in our sole discretion, agree to such request, or if we cancel a
Contract as provided in this Agreement (a) you will, except as provided
otherwise in the Limitation of Liability and Indemnity section of this
Agreement, indemnify and reimburse us for, and hold us harmless from and
against, all our Losses which arise directly or indirectly as a result of, or
are in any way connected with, such cancellation or extension, including,
without limitation, the liquidation of our position in the currency of the
Contract, and (b) we may setoff and apply against your liability to us any of
your cash, deposit accounts, securities, securities accounts or other property
we hold or any other obligations we have to you, without regard to the nature or
due date of such deposits or obligations and notwithstanding that such setoff
may give rise to penalties for early withdrawal of funds.

        8. LIMITATION OF LIABILITY AND INDEMNITY. Except to the extent your
Losses or our Losses are caused directly by our gross negligence or willful
misconduct, and subject to the remaining provisions of this section, we shall
not be liable for any of your Losses, and you shall be liable for our Losses, to
the extent your or our Losses arise directly or indirectly as a result of, or
are in any way connected with, (a) the enactment or imposition after the date of
this Agreement of, or the change after the date of this Agreement in, any laws,
regulations, guidelines or other directives of any government or government
entity affecting the Contracts or Transactions; provided, however, that your
liability for our Losses and the limitation of our liability for your Losses
will not apply to the extent we knew about such enactment, imposition, or change
before it became effective and could have refused to enter into such Contracts
or Transactions without causing any Losses to us and without violating the terms
of this Agreement or any Contract, (b) the errors, acts or omissions of others,
such as communications carriers or correspondents through which we may perform,
or receive or transmit information in performing, our obligations under this
Agreement or any Contract, (c) any event or circumstance beyond our control, or
(d) any actions performed by us, or any actions not performed by us, in
compliance with the terms of this Agreement or any Contract. With respect to
your Losses and our Losses which arise directly or indirectly as a result of, or
which are in any way connected with, your or our performance or failure to
perform obligations under this Agreement or any Contract, we and you will
negotiate in good faith in an effort to reach a mutually satisfactory allocation
of such Losses. It is understood, however, that in such circumstances and unless
otherwise agreed by you and us in such negotiations, we will not be responsible
to you for any of your Losses, and you will indemnify us for any of our Losses,
arising from claims by third parties who through their connection with you are
affected by the Contracts or Transactions, if such Losses result from any cause
other than our breach of this Agreement or any Contract or our negligence, gross
negligence, or willful misconduct. To the extent the Losses referred to in the
preceding sentence are caused by our breach of this Agreement or any Contract or
by our negligence, you understand that (i) if our breach or negligence is the
late payment of any amount due from us to you under any Contract, including, but
not limited to, any late payment caused by our having to re-execute for any
reason a Transaction covered by a Contract, our liability for your Losses in

<PAGE>

Fair, Isaac and Company, Incorporated
November 1, 2002
Page 6

such circumstances shall be limited to the interest on the amount due for the
time period such amount remains due and unpaid calculated at that interest rate
which is standard for late payments in the foreign exchange market, and your
indemnification obligations shall extend to only that amount of our Losses which
exceed such interest, and (ii) in all other cases, our liability for your Losses
will be limited to those money damages arising directly as a result of such
breach or negligence, and your indemnification obligations shall extend to only
that amount of our Losses which exceed such direct money damages. You also agree
to indemnify us for our Losses which arise directly or indirectly as a result
of, or which are in any way connected with, the enforcement or protection of our
rights under this Agreement and the Contracts. IN NO EVENT WILL WE BE LIABLE FOR
ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES, WHETHER
ANY CLAIM IS BASED ON CONTRACT OR TORT, WHETHER THE LIKELIHOOD OF SUCH DAMAGES
WAS KNOWN TO US, AND REGARDLESS OF THE FORM OF THE CLAIM OR ACTION. Any action
against us under or related to this Agreement or any Contract must be brought
within twelve (12) months after the cause of action arises.

        9. NETTING. If on any date each party to this Agreement is to pay the
other party the same aggregate amount in the same currency, then, on such date,
unless both parties specifically agree otherwise, each party's obligation to
make payment of such amount will be automatically satisfied and discharged
without any payment being made. If on any date the parties are to pay each other
differing aggregate amounts in the same currency, each party's payment
obligation will be replaced by an obligation of only the party having to pay the
larger aggregate amount to pay to the other party the excess of the larger
aggregate amount over the smaller aggregate amount.

        10. TERMINATION. Either of us may terminate this Agreement at any time
with or without cause upon notice in writing to the other party. Upon such
termination your obligations to us and our obligations to you under this
Agreement will also terminate, except for (a) any obligations in connection with
any Contract which is in existence at such time and cannot be canceled under the
provisions of Section 6 of this Agreement, and (b) any obligations which, by the
terms of this Agreement, survive such termination. All the obligations of the
parties under this Agreement will survive the termination of any or all the
Contracts, and the obligations of the parties under Sections 4, 6, 7, 8, 9 and
10 of this Agreement will survive the termination of this Agreement.

        11. MODIFICATIONS, AMENDMENTS, AND WAIVERS. This Agreement may not be
modified or amended, nor may any provision of this Agreement be waived, except
in a writing signed by you and us.

        12. NOTICES. Notices from one party to this Agreement to the other party
shall be in writing, or be made by a telecommunications device capable of
creating a written record, shall be delivered to the addressee at its address
specified above, or to any other address a party may designate by written notice
to the other party, and shall be effective upon receipt.

        13. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and
inure to the benefit of each of your and our respective heirs, legal
representatives, successors and assigns; provided however, that you may not
assign or otherwise transfer any of your rights

<PAGE>

Fair, Isaac and Company, Incorporated
November 1, 2002
Page 7

or obligations under this Agreement or any Contract without our prior written
consent, which consent will not be unreasonably withheld.

        14. GOVERNING LAW. This Agreement and all Contracts shall be governed by
and be construed in accordance with the laws of the State of California.

        15. SEVERABILITY. If any provision of this Agreement shall be prohibited
or invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity without invalidating the remainder of
such provision or any remaining provisions of this Agreement.

        16. ENTIRE AGREEMENT. This Agreement, together with each Contract and
any writing referring specifically to this Agreement or any Contract or
referring in general to agreements or contracts which would include this
Agreement or any Contract, contains the entire and only agreement between you
and us with respect to your purchase from us or sale to us of foreign currencies
and the terms of all Contracts for any such purchase or sale.

        Please indicate your acceptance of the terms and conditions of this
Agreement by signing, dating and returning a copy of this Agreement to us at our
address specified above.

                                              Very truly yours,

                  (i)      The increase in Basic Rent provided by this Section
4.2 shall be in addition to any Excess Direct Operating Expenses Rent increases
provided in Section 4.3. All references in this Lease to Basic Rent shall

         4.3      EXCESS DIRECT OPERATING EXPENSES RENT:

                  (a)      Subject to any limitations or exceptions stated in
Section 1.5 or elsewhere provided, from and after the Commencement Date, Tenant
agrees to pay to Landlord, as additional rent, Tenant's Pro Rata Share of Excess
Direct Operating Expenses (hereinafter defined) incurred by Landlord ("Excess
Direct Operating Expenses Rent"). Tenant shall pay to Landlord, Tenant's Excess
Direct Operating Expenses Rent pursuant to the following procedures:

                           (i)      Landlord  shall  provide to Tenant a good
faith estimate of the annual Direct Operating Expenses and the total amount of
annual Excess Direct Operating Expenses Rent with respect to each lease year of
the Term. Each such estimate shall be provided by Landlord to Tenant as soon as
possible following the first day of such lease year;

<PAGE>
                           (ii)     Each estimate of total annual Excess Direct
Operating Expenses Rent determined by Landlord pursuant to this Section, shall
be divided into twelve (12) equal monthly installments. Tenant shall pay to
Landlord such monthly installment of Excess Direct Operating Expenses Rent with
each monthly payment of Basic Rent pursuant to Section 4.1 above. In the event
the estimated amount of Excess Direct Operating Expenses Rent has not yet been
determined for any lease year, Tenant shall pay the monthly installment in the
estimated amount determined for the preceding lease year until the estimate for
the current lease year has been provided to Tenant, at which time Tenant shall,
within thirty (30) days following receipt of the notice pay to Landlord any
existing shortfall and, thereafter, make the monthly installment payment in
accordance with the current estimate;

                           (iii)    As soon as reasonably possible following the
end of each lease year of the term including the end of any initial particular
lease year, Landlord shall determine and provide to Tenant a statement of the
amount of Direct Operating Expenses actually incurred (except in the event that
the Building is less than ninety-five percent (95%) occupied, in which case the
Direct Operating Expenses shall be computed as though the Building had been
ninety-five percent (95%) occupied) and the amount of Excess Direct Operating
Expenses Rent payable by Tenant with respect to such lease year. In the event
the amount of such Excess Direct Operating Expenses Rent exceeds the sum of the
monthly installments actually paid by Tenant, pursuant to Section 4.3(a)(ii)
above, for such lease year, Tenant shall pay to Landlord, on the first day of
the calendar month immediately following receipt of such statement, the
difference. In the event the sum of such installments exceeds the amount of
Excess Direct Operating Expenses Rent actually due and owing, the difference
shall be applied as a credit to Excess Direct Operating Expenses Rent payable by
Tenant pursuant to Section 4.3(a)(ii). In no event shall the adjustment of
Excess Direct Operating Expenses Rent decrease the amount of Basic Rent due and
payable to Landlord under this Lease.

                  (b)      For purposes of this Section, the following terms
shall have the following prescribed meanings:

                           (i)      The term "Building" means the Building as
defined in Article 2, and the parking areas and other structures servicing the

                           (ii)     The term "Direct Operating Expenses" as used

<PAGE>
                                    (8) The costs of any additional services not
provided to the Building at the Commencement Date but thereafter provided by
Landlord in prudent management of the Building or at the direction of or
resulting from statutes or regulations, or interpretations thereof, promulgated
by any governmental authority in connection with the use or occupancy of the

                                    (9) The costs of any capital improvements or
alterations made to the Building after the Commencement Date that reduce other
operating expenses or are required at the direction of or resulting from,
statutes or regulations, or interpretations thereof, promulgated by any
governmental authority in connection with the use or occupancy of the Building
that were not applicable when such improvements were originally constructed,
such cost thereof to be amortized over such reasonable period, i.e., generally
acceptable accounting practices, as Landlord shall determine, together with
interest on the unamortized balance at the actual rate paid by Landlord on funds
borrowed for the purpose of constructing said capital improvements plus any
financing costs.

                                    (10) All taxes and assessments levied on the
Building (including, without limitation, the land upon which it is located),
including, but not limited to, real property taxes and assessments, and personal
property taxes and assessments on all personal property of Landlord used in
connection with the maintenance and operation of the Building and the reasonable
costs incurred by Landlord in contesting, in good faith and by appropriate
proceedings the amount or validity of any such tax or assessment.

                           (iii)    The term "Excess Direct Operating Expenses"
shall mean the amount, if any, that Direct Operating Expenses paid or incurred
by Landlord during a lease year, exceeds the Initial Direct Operating Expenses.

         4.4      ADDITIONAL RENT: Tenant shall pay to Landlord as additional
rent ("Additional Rent") and without notice, abatement, deduction or set off,
all sums, costs and expenses which Tenant, in any of the provisions of this
Lease, or through a separate agreement relating to the Premises and/or the
Building, assumes or agrees to pay, including, but not limited to, tenant
improvement work, whether or not any of such sums, costs and expenses are
specifically described in Additional Rent. In the event of any nonpayment of
Additional Rent when required under this Lease, the Landlord shall have (in
addition to all other rights and remedies) all the rights and remedies provided
herein or by law in the case of non-payment of Basic Rent and Excess Direct
Operating Expenses Rent. All references in this Lease to Rent shall mean and
collectively refer to Basic Rent, Excess Direct Operating Expenses Rent and
Additional Rent

         4.5      LATE CHARGES: Tenant's failure to pay Rent promptly on the
first day of each month may cause Landlord to incur unanticipated costs, the
exact amount of which are impractical or extremely difficult to ascertain. Such
costs may include, but are not limited to, processing and accounting charges and
late charges which may be imposed on Landlord by any ground lease, mortgage or
trust deed encumbering the Building. Therefore, if Landlord does not receive any
Rent payment within ten (10) days after it becomes due, Tenant shall pay
Landlord a late charge equal to six percent (6%) of the overdue amount. The
parties agree that such late charge represents a fair and reasonable estimate of
the costs Landlord will incur by reason of such late payment.

         4.6      INTEREST: Any amount owed by Tenant to Landlord which is not
paid when due shall bear interest at the rate of twelve percent (12%) per annum
from the due date of such amount. However, interest shall not be payable on late
charges to be paid by Tenant under this Lease. The payment of interest on such
amounts shall not excuse or cure any default by Tenant under this Lease. If the
interest rate specified in this Lease is higher than the rate permitted by law,
the interest rate is hereby decreased to the maximum legal interest rate
permitted by law.

         4.7      SECURITY DEPOSIT: Tenant shall pay to Landlord, immediately
upon execution of this Lease, the Security Deposit, which shall be held by
Landlord as security for the faithful performance by Tenant of all of the terms,
covenants and conditions of this Lease to be kept and performed by Tenant during
the Term hereof. If Tenant defaults with respect to any provision of the Lease,
including but not limited to, the provisions relating to the payment of Rent,
Landlord may (but shall not be required to) use, apply or retain all or any part
of the Security Deposit for the payment of any Rent or any other sum in default,
or for the payment of any other amount which Landlord may spend or become
obligated to spend by reason of Tenant's default or to compensate Landlord for
any other loss or damage which landlord may suffer by reason of Tenant's
default. If any portion of the Security Deposit is so used or applied, Tenant
shall, upon demand therefor, deposit with Landlord cash, in an amount sufficient
to restore the Security Deposit to its original amount and Tenant's failure to
do so shall be a material breach of this Lease. Landlord shall not be required
to keep the Security Deposit separate from its general funds, and Tenant shall
not be entitled to interest on the Security Deposit. If Tenant shall fully and
faithfully perform every provision of this Lease to be performed by it, the
Security Deposit or any balance thereof shall be returned to Tenant (or at
Landlord's option to the last assignee of Tenant's interest hereunder) within
thirty (30) days following expiration of the Term, provided that Landlord may
retain the Security Deposit until such time as any amount due from Tenant in
accordance hereof has been determined paid in full.

ordinances, rules and regulations pertaining to the use of the Premises, and/or
Building. Tenant shall not do or permit anything to be done in or about the
Premises which will, in any way, obstruct or interfere with the rights of other
tenants or occupants of the Building, or injure them, or allow the Premises to
be used for any immoral or unlawful purpose, nor shall Tenant cause, maintain or
permit any nuisance in, on or about the Premises. Tenant agrees to abide by all
reasonable rules and regulations established by Landlord from time to time with
respect to the Building. A copy of the rules and regulations in existence on the
date of this Lease is attached hereto as Exhibit B, but Landlord reserves the
right to amend the rules and regulations at any time by giving notice of
amendment to Tenant, if Landlord determines such amendments to be in the best
interest of the Building and its tenants.

         With respect to any floor of the Building that is entirely leased by
Tenant, including initially the third floor, Tenant shall be responsible for
ensuring, at its sole cost and expense, that all areas within such floor
(including restroom and lobby areas) comply with all applicable laws. Landlord
shall be responsible for ensuring that any common areas within the Building
other than on floors that are entirely leased to Tenant comply with all
applicable laws. Notwithstanding the foregoing, Tenant shall be solely
responsible for all costs relating to compliance with legal requirements to the
extent triggered, caused or made applicable by any alteration, addition or
improvement made by Tenant

         5.3      INSURANCE USE REQUIREMENTS: Tenant shall neither use nor
occupy the Premises in any manner, nor commit or omit any act, which would
result in a cancellation or reduction of any insurance or increase in premiums
on any insurance policy covering the Premises, or the property or Building.
Tenant shall, at its expense, comply with all requirements of any insurer
pertaining to use of the Premises and any other requirement which are reasonably
necessary for the maintenance of economic and proper fire, liability and other
insurance desired to be carried by Landlord

                     ARTICLE 6. IMPROVEMENTS TO THE PREMISES

         6.1      LANDLORD'S WORK: INTENTIONALLY DELETED.

and, if required by Tenant's plans and specifications, modifications to the fire
sprinkler system shall be made by or at the direction of Landlord pursuant to
plans and specifications to be approved in writing by Landlord and Tenant
("Tenant Improvements"). The Tenant Improvements and the responsibility for
preparation of plans and specifications required to construct the same are
described in the Work Letter Agreement, attached hereto as Exhibit C. Landlord
shall have complete and absolute discretion to select such persons and companies
as it reasonably deems proper for designing, constructing or supplying all
Tenant Improvements. By accepting occupancy of the Premises, Tenant acknowledges
completion of all improvements constituting the Premises, including, but not
limited to, Tenant Improvements and Landlord's Work.

         6.3      PAYMENT FOR TENANT IMPROVEMENTS: Landlord shall pay, pursuant
to the terms and conditions of the Work Letter Agreement, the cost and expense
of Tenant Improvements in an amount not to exceed the Tenant Improvement
Allowance. The cost and expense of any Tenant Improvements in excess of the
Tenant Improvement Allowance, shall be paid by the Tenant in accordance with the
provisions of the Work Letter Agreement.

         6.4      ESTIMATED COMPLETION DATE: The Tenant Improvements shall be
completed on or before the Estimated Completion Date. Landlord shall endeavor to
give Tenant minimum thirty (30) day notice of the Estimated Completion Date. In
the event that the Tenant Improvements are not completed on or before the
Estimated Completion Date, for any cause or reason, Landlord, its agents and
employees, shall not be liable or responsible for any damages or liabilities in
connection therewith incurred by Tenant as a result thereof, nor shall the
obligations of Tenant provided herein be excused by reason of any such delay,
except that the failure to complete construction of the Tenant's Improvements on
the Estimated Completion Date is due solely to the unexcused actions of Landlord
hereunder, then, in such event, Tenant's sole remedy and right shall be to delay
the Commencement Date by the number of days that completion of construction of
the Tenant Improvements were delayed solely by the unexcused actions of
Landlord, but in no event shall the Commencement Date be later than the date on
which Tenant takes possession or

commences business operations at the Premises or part thereof. Notwithstanding
the foregoing, if Landlord has not completed construction of the Tenant
Improvements and tendered possession of the Premises to Tenant within one
hundred fifty (150) days from the Estimated Completion Date, and such delay was
not the result of either (i) delays caused by force majeure or (ii) act or
omission of Tenant or anyone for whom Tenant is responsible, then Tenant may, at
its option, by notice in writing to Landlord given within thirty (30) days
thereafter, cancel this Lease. If Tenant cancels this Lease in accordance with
the foregoing, the Landlord shall return to Tenant, without interest, the first
installment of Basic Rent, paid pursuant to Section 4.1 above, plus the Security
Deposit (if previously deposited by Tenant) and the parties shall be discharged
from any and all obligations hereunder. Notwithstanding the foregoing, the
Commencement Date shall be the date when Landlord would otherwise have been able
to tender possession of the Premises or complete construction thereof except for
the delay which was caused by the acts or omissions of Tenant or anyone for whom
Tenant is responsible, even though (i) Tenant may not, in fact, occupy the
Premises on such date; (ii) the Tenant Improvements were not, in fact, completed
on the Estimated Completion Date, and (iii) Landlord actually completes the
Tenant Improvements after the Estimated Completion Date and delivers possession
of the Premises after the Commencement Date. See Work Letter Section 5.

         6.5      EARLY OCCUPANCY: Provided Landlord gives Tenant a minimum
thirty (30) days prior notice and if Tenant occupies the Premises prior to the
Commencement Date, Tenant's occupancy of the Premises shall be subject to all of
the provisions of this Lease. Early occupancy of the Premises shall not advance
the Termination Date of this Lease. Tenant shall pay Base Rent and all other
charges specified in this Lease for the early occupancy period.

            ARTICLE 7. MAINTENANCE, REPAIR AND ALTERATION OF PREMISES

         7.1      MAINTENANCE: Subject to Article 6 and Work Letter Agreement,
by taking possession of the Premises, Tenant shall be deemed to have accepted
the Premises as being in good, sanitary order, condition, and repair except for
punch list items. Tenant shall, at Tenant's sole cost and expense, keep and
maintain the Premises and every part thereof in good condition and repair,
ordinary wear and tear excepted. Except as specifically provided in Section 6.1
of this Lease, Landlord shall have no obligation whatsoever to alter, remodel,
improve, repair, decorate or paint the Premises or any part thereof, and the
parties hereto affirm that Landlord has made no representations to Tenant
respecting the condition of the Premises or the Building.

         7.2      REPAIRS: Notwithstanding the provisions of Section 7.1 above,
Landlord shall repair and maintain the structure portions, structural walls,
utilities underground, sewer, roof structure, foundation and sub-flooring of the
Building unless such maintenance and repairs are caused in part or in whole by
the act, neglect, fault, or omission of any duty by the Tenant, its agents,
servants, employees, contractors, licensees or invites, in which case Tenant
shall pay Landlord the reasonable cost of such maintenance and repairs. Landlord
shall not be liable for any such repairs or to perform any maintenance unless
such failure shall persist for an unreasonable time after written notice of the
need of such repairs or maintenance is given to Landlord by Tenant. Except as
provided in Article 13 hereof, there shall be no abatement of any item of Rent
and no liability of Landlord by reason of any injury to or interference with
Tenant's business arising from the making of any repairs, alterations, or
improvements in or to any portion of the Building or the Premises or in or to
fixtures, appurtenances, and equipment therein. Tenant waives the right to make
repairs at Landlord's expense under any law, statute, or ordinance now or
hereafter in effect.

         7.3      ALTERATIONS: Subject to the removal/nonremoval qualifications
stated in Section 7.5, Tenant shall not make any alteration, addition, or
improvement to the Premises (whether structural or nonstructural) without the
prior written consent of Landlord, which consent will not be unreasonably
withheld. Tenant may, with notice to Landlord, make nonstructural
modifications/alterations (to exclude, but not be limited to, base building,
electrical, power, sewer, roof, etc.) if Tenant's expenditure per occurrence is
less than $5,000.00 cumulative. In the event Landlord gives its consent, such
consent may be conditioned upon the requirement that Tenant (i) supply to
Landlord, plans and specifications which must be approved by Landlord in writing
prior to commencement of any work; and (ii) provide, prior to the commencement
of any work, a lien free completion bond in the form and amount satisfactory to
Landlord. Any alteration, addition, or improvement for which Landlord gives its
written consent shall be accomplished by Tenant in a good and workmanlike
manner; in conformity with all applicable laws and regulations and by a
contractor approved by Landlord. Upon completion of any such work, Tenant shall
provide to Landlord "as-built" plans, copies, and proof of payment of all labor
and materials. Tenant shall pay, when due, all claims for such labor and
materials and shall give Landlord at least ten (10) days prior written notice of
the commencement of any such work. Landlord may enter upon the Premises, in such
case, for the purpose of posting appropriate notices, including, but not limited
to, notices of non-responsibility. Any Tenant alterations which cause or trigger
an increase in Landlord's tax assessment shall be incrementally passed directly
through to Tenant. Further, the tax increase shall not be computed in
calculating the Initial Base Operating Expenses per Article 1.5 or as provided.
See Addendum Paragraph 6 for other requirements.

         7.4      LIENS: Tenant shall keep the Premises free from any liens
arising out of any work performed, materials furnished, or obligations incurred
by or for Tenant. In the event that Tenant shall not, within ten (10) days
following the imposition of any such lien, cause the same to be released of
record by payment or posting of a proper bond, Landlord shall have, in addition
to all other remedies provided herein and by law, the right, but not the
obligation, to cause the same to be released by such means as it shall deem
proper, including payment of or defense against the claim giving rise to such
lien. All sums paid by Landlord and all expenses incurred by it in connection
therewith shall create automatically an obligation of Tenant to pay an
equivalent amount as additional rent, which additional rent shall be payable by
Tenant on Landlord's demand with interest at the maximum rate per annum
permitted by law until paid.

         7.5      CONDITION ON TERMINATION: Upon the expiration, or sooner
termination, of the Lease, Tenant shall surrender the Premises to Landlord,
broom clean, and in the same condition as received, except for ordinary wear and
tear which Tenant was not otherwise obligated to remedy, under any provision of
this Lease. Except for the improvements constructed pursuant to Article 6
hereof, Landlord may require Tenant to remove any alterations, additions or
improvements made by Tenant prior to the termination of the Lease and to restore
the Premises to its prior condition (i.e., the condition as of the Commencement
Date), all at Tenant's expense. All alterations, additions, and improvements
which Landlord does not require Tenant to remove shall become Landlord's
property and shall be surrendered to Landlord upon termination of the Lease. In
no event shall Tenant remove any materials or equipment (excluding trade
fixtures) from the Premises without Landlord's prior written consent, including,
but not limited to, any power wiring or power panels, lighting or lighting
fixtures, wall coverings, window coverings, carpets, other floor coverings,
heaters, air conditioners or any other heating or air conditioning equipment,
fencing or security gates or other similar Building operating equipment and
decorations. Notwithstanding, if Landlord approves a Tenant alteration as
described in Section 7.3, then Landlord, with its consent, shall condition its
approval either (i) to be removed at Lease expiration at Tenant's expense or
(ii) not be removed.

Landlord be liable to Tenant if any utility service to the Premises and/or
Building is interrupted or terminated because of repairs, installations,
improvements or causes beyond Landlord's control, nor shall any such
interruption or termination be construed as an eviction (actual or constructive)
of Tenant, nor entitle Tenant to an abatement of any item of Rent, nor relieve
Tenant from fulfillment of any covenant or condition of this Lease. Tenant
requested services shall be provided by Landlord, at an hourly rate established
by Landlord from time to time, during additional hours on reasonable notice to
Landlord, at Tenant's sole cost and expense, and payable by Tenant, as billed,

advance written consent of Landlord, which consent may be withheld for any
reason. If any sign, advertisement, notice or similar matter is improperly
placed by Tenant, Landlord shall have the right to remove the same, and Tenant
shall be liable for any and all expenses incurred by Landlord by the removal.
Any signs, advertisement, notice or similar matter (including, but not limited
to, directories and nameplates) approved by Landlord shall be at the sole cost

                  ARTICLE 12. LIABILITY INSURANCE AND INDEMNITY

         12.1     TENANT INSURANCE: Tenant, at its own expense, shall provide
and keep in force with companies reasonably acceptable to Landlord or Landlord's

                  (a)      Broad form commercial general liability insurance, or
equivalent, written on an occurrence form against liability for bodily injury
and property damage arising out of or in connection with the use, occupancy or
maintenance by Tenant of the Premises (including, without limitation, personal
injury coverage and contractual liability insurance specifically covering
liability with respect to the indemnity described in Section 12.4 below) in the
amount of not less than Three Million Dollars ($3,000,000.00) in respect to
injuries or death, and in the amount of not less than Three Hundred Thousand
Dollars ($300,000.00) per occurrence in respect to damage to property;

                  (b)      Fire insurance with standard form extended coverage

other personal property which may, from time to time, be located upon the
Premises; and

                  (c)      Such other insurance as Tenant or Landlord or any
beneficiary of any deed of trust encumbering the Building or the Property of
which the Premises are a part, may from time to time, reasonably require, in
form, amount and protecting against such risks as would be obtained by a prudent
person.

         Each of the foregoing policies of insurance shall name the Landlord and
any mortgagee as an additional insured. The policy limits herein specified shall
be increased, from time to time, upon written demand from Landlord, if Tenant's

part of blanket policies containing a "per project, per location" endorsement.
Landlord makes no representation that the minimum insurance amounts specified
above are adequate to protect Tenant, and the amount of insurance obtained by
Tenant shall not limit Tenant's liability under this Lease. Tenant shall furnish
Landlord with a certificate of such policy prior to taking possession of the
Premises or occupying any part thereof and whenever requested shall satisfy
Landlord that such policy is in full force and effect. Each policy shall be
primary and non-contributing with any insurance carried by Landlord. Each policy
shall further provide that it shall not be canceled or materially altered
without thirty (30) days prior written notice to Landlord.

obligations of Tenant under this Section will survive the expiration or any
termination of this Lease.

condemnation, or as of the date possession is taken by the condemning authority,
whichever is earlier. If a partial taking so renders the balance of the Premises
unusable by Tenant, Tenant shall give written notice thereof to Landlord within
thirty (30) days of the taking. No award of any partial or entire taking shall
be apportioned and Tenant hereby assigns to Landlord any award which may be made
in such taking or condemnation, together with any and all rights of Tenant now

Premises which does not result in a termination of this Lease pursuant to
Section 13.3, rent shall be abated, effective as of the date possession of the
Premises is required to be surrendered, in proportion to the part of the
Premises so made unusable by Tenant. Landlord shall, at its expense, restore the
portion of the Premises remaining usable to as near its former condition as
reasonably possible using that portion of the condemnation award attributable to
such restoration costs.

                           (i) Landlord can continue this Lease in full force
and effect without terminating Tenant's right of possession, and Landlord shall
have the right to collect rent and other monetary charges when due and to
enforce all other obligations of Tenant hereunder. Landlord shall have the right
to enter the Premises to do acts of maintenance and preservation of the
Premises, to make alterations and repairs in order to relet the Premises, and /
or to undertake other efforts to relet the Premises. Landlord may also remove

given by Landlord to Tenant or unless the termination is decreed by a court of
competent jurisdiction

                           (ii) In furtherance of the remedy set forth in this
Section, Landlord may relet the Premises or any part thereof for Tenant's
account, for such term (which may extend beyond the Lease term), at such rent,

sole discretion. Tenant shall be liable immediately to Landlord for all costs
Landlord incurs in reletting the Premises. Any rents received by Landlord from
such reletting shall be applied to the payment of: (a) first, any indebtedness
other than rent due hereunder from Tenant to Landlord; (b) second, the costs of
such reletting, including brokerage and attorney's fees and the cost of any
alterations and repairs to the Premises; and (c) third, the payment of rent due
and unpaid hereunder. Any remainder shall be held by Landlord and applied in
payment of future amounts as the same become due and payable hereunder. In no
event shall Tenant be entitled to any excess rent received by Landlord after a
breach of this Lease by Tenant and the exercise of Landlord's remedies
hereunder. If the rent from such reletting during any month is less than the
rent payable hereunder, Tenant shall pay such deficiency to Landlord immediately
upon demand.

         14.2     WORTH AT THE TIME OF AWARD. As used in Sections 14.1(a)(i) and
14.1(a)(ii) above, the "worth at the time of award" shall be computed by
allowing interest at the lesser of twelve percent (12%) per annum or the maximum
rate permitted by law. As used in Section 14.1 (a) (iii), above, the "worth at
the time of award" shall be computed by discounting such amount at the discount
rate of the Federal Reserve Bank of San Francisco at the time of award plus one
percentage point.

         14.3     NOTIFICATION OF RELETTING: In the event Landlord terminates
this Lease pursuant to Section 14.1(a) above, and Tenant has made an advance
payment of rent as defined in California Civil Code Article 1951.7, and Tenant
has requested in writing that Landlord notify it of any initial reletting of
Premises, then and only then must Landlord notify Tenant pursuant to California
Civil Code Article 1951.7(c) that the Premises have been relet.

         14.4     RIGHT OF LANDLORD TO RE-ENTER: In the event of any termination
of this Lease, Landlord shall have the immediate right to enter upon and
repossess the Premises, and any personal property of Tenant may be removed from
the Premises and stored in any public warehouse at the risk and expense of
Tenant.

         14.5     LANDLORD'S LIEN: INTENTIONALLY DELETED

         14.6     LANDLORD'S RIGHT TO PURSUE OTHER REMEDIES: In the event of any
breach of this Lease, Landlord may pursue any of the foregoing remedies, and
Landlord may consecutively or concurrently therewith pursue any other remedy or
enforce any right to which Landlord may be entitled by law.

                            ARTICLE 15. SUBORDINATION

          15.1    This Lease and the leasehold estate created hereby are and
shall be, at the option and upon written declaration of Landlord, subject,
subordinate and inferior to the lien and estate of any liens, trust deeds and
encumbrances, and all renewals, extensions or replacements thereof, now or
hereafter imposed by Landlord upon the Premises or any part of the Building.
Landlord hereby expressly reserves the right, at its option and declaration, to
place liens, trust deeds and encumbrances upon and against the Premises

and/or any part thereof and/or the Building, superior in lien and effect to this
Lease and the estate created hereby. The execution by Landlord and the recording
in the Office of the County Recorder of the county in which the Premises are
situated, of a declaration that this Lease and leasehold estate are subject,
subordinate and inferior to any lien, trust deed or encumbrance placed by
Landlord upon or against the Premises, and/or any part thereof and/or the
Building, shall, of and by itself (in favor of any lien or, mortgagee,
beneficiary, trustee or title insurance company insuring the interest of any
such person) and without further notice to or act or agreement of Tenant, make
this Lease and the estate created hereby subject, subordinate and inferior
thereto. Notwithstanding the foregoing, Tenant agrees, on request of Landlord,
to forthwith execute and acknowledge any reasonable subordination agreement or
other documents required to establish of record the priority of any such
encumbrance over this Lease, and also to execute and deliver to Landlord,
promptly on request, any reasonable estoppel certificate or other statement to
be furnished to any prospective purchaser or lender against the Premises stating
the matters specified in Article 27 hereof.

          15.2    In the event any proceedings are brought for foreclosure, or
in the event of the exercise of the power of sale under any mortgage or deed of
trust made by the Landlord covering the Premises, the Tenant shall attorn to the
purchaser upon any such foreclosure or sale and recognize such purchaser as the
Landlord under this Lease.

          15.3    The provisions of this Article to the contrary
notwithstanding, and so long as Tenant is not in default hereunder, this Lease
shall remain in full force and effect for the full term hereof.

          15.4    Landlord agrees to use reasonable best efforts to obtain and
deliver to Tenant, at Tenant's expense, a commercially reasonable
non-disturbance agreement from any lender with a lien on the Building senior to
this Lease.

                           ARTICLE 16. ATTORNEY'S FEES

          In case any suit shall be brought for any unlawful detainer of the
Premises, for the recovery of any Rent due under this Lease, or because of the
breach or alleged breach of any other covenant herein contained on the part of
either party to be kept or performed, the prevailing party shall recover from
the non-prevailing party all costs and expenses incurred therein, including
reasonable attorney's fees, and reasonable attorney's fees and expenses incurred
in enforcing any judgment. Further, (i) if for any reason Landlord consults
legal counsel or otherwise incurs any reasonable costs or expenses as a result
of its rightful attempt to enforce the provisions of this Lease, even though no
litigation is commenced, or if commenced is not pursued to final judgment or
(ii) Landlord is named as a defendant in any suit brought against Tenant in
connection with or arising out of Tenant's occupancy hereunder, Tenant shall be
obligated to pay to Landlord, in addition to all other amounts for which Tenant
is obligated hereunder, all of Landlord's reasonable costs and expenses incurred
in connection with any such acts, including reasonable attorneys' fees.

                     ARTICLE 17. ASSIGNMENT AND SUBLETTING

          17.1    LANDLORD'S CONSENT REQUIRED: The purpose of this Lease is to
transfer possession of the Premises to Tenant for Tenant's personal use and
Tenant has not entered into this Lease for the purpose of obtaining the right to
convey the leasehold to others. The ability of Tenant to assign or sublet the
Premises is subsidiary and incidental to the underlying purpose of this Lease.
Tenant will not, either voluntarily or by operation of law, assign, transfer,
mortgage, pledge, hypothecate or encumber this Lease or any interest herein, and
will not sublet the Premises or any part thereof or any right or privilege
appurtenant thereto, or allow any other person (the employees, agents, servants
and invitees of Tenant excepted) to occupy or use the Premises or any portion
thereof, without the prior written consent of Landlord, which consent will not
be unreasonably withheld. Provided Tenant has received Landlord's consent
herein, Tenant agrees throughout the term of this Lease not to sublease to more
than four (4) tenants total. Any cumulative transfer of more than thirty percent
(30%) of the voting stock will be deemed to be an assignment by Tenant of this
Lease which requires the prior written notice to Landlord provided the
controlling entity has a consolidated net worth equal to or greater than
Tenant's. If notice is given to Landlord, then the controlling entity shall
submit to Landlord for its approval all reasonably required financial
documentation to support the financial qualifications.

          Any transfer or subletting attempted or concluded without Landlord's
prior written consent will be void and will constitute a default under this
Lease. Consent by Landlord to any transfer (including, but not limited to, an
assignment or subletting), shall be limited to the particular transfer approved
by Landlord and shall not be deemed to be Landlord's consent to any subsequent
transfer. Tenant acknowledges Landlord shall have no obligation to sublessees
and Tenant agrees to be responsible for such parties' compliance with all rules,
regulations, and other covenants.

<PAGE>
         17.2     LANDLORD'S ELECTION: Tenant's request for consent to any
transfer, described in Section 17.1 above must be accompanied by a written
statement setting forth the details of the proposed transfer, including the
name, type of business and financial condition (supported by financial
statements) of the prospective transferee, financial details of the proposed
transfer (e.g. the terms of the transaction, the rent and security deposit
payable under any assignment or sublease), copies of all agreements and other
writings pertaining in any way to the proposed transfer. Tenant, in addition to
the foregoing information which must be delivered to Landlord at the time Tenant
requests Landlord's consent to the proposed transfer, shall deliver to Landlord
any additional information concerning the proposed transfer or prospective
transferee as Landlord may reasonably request. Landlord will have the right (i)
to reasonably withhold consent; (ii) to grant written consent to the transfer;
or (iii) to terminate this Lease as of the date of the proposed transfer as to
that portion of the Premises affected by the proposed transfer provided the
third party transfer term is greater than thirty-nine (39) months long. Within
fifteen (15) business days after submission of all required information for the
request for consent of proposed transfer, Landlord shall give notice to Tenant
of its election under this Section. If Landlord does waive in writing its right
to terminate this Lease, such waiver shall be effective only for the transfer
specifically covered in Tenant's notice for a period of sixty (60) days after
the date of the waiver. If Landlord elects to terminate this Lease under Section
1 7.2(iii) above, Tenant shall have the right to withdraw its request to the
proposed transfer within fifteen (15) days after Landlord's election to
terminate this Lease, in which case Landlord shall have no right to terminate
this Lease or any portion thereof. If Landlord does duly exercise its rights
under Section 1 7.2(iii) above to terminate this Lease or any portion thereof,
Landlord shall have the right to enter into a lease or other occupancy agreement
directly with the prospective transferee, and Tenant shall have no right to any
of the rents or other consideration payable by such prospective transferee under
such other lease, even if such rents and other consideration exceed the rent
payable under this Lease by Tenant. If Landlord elects to exercise its rights
under Section 17.2(iii), then Landlord shall have the right to lease the
Premises to any other tenant, or not lease the Premises, in its sole discretion.
in the event of a sublease or assignment of a portion of the Premises, to which
Landlord has elected to exercise its rights under Section 1 7.2(iii) above,
Landlord and Tenant shall enter into an amendment of this Lease to effect a
proportionate reduction in the size of the Premises and in the Basic Rent or
other Additional Rent payable hereunder.

         17.3     WITHHOLDING CONSENT: Under Section 17.2(i), Landlord may
withhold its consent to the proposed transfer on any reasonable ground. Such
reasonable grounds shall include, without limitation, any one or more of the
following:

                  (i)      That the prospective transferee's financial condition
is or may become insufficient to support all of the financial and other
obligations of this Lease;

                  (ii)     That the use to which the Premises will be put by the
prospective transferee is inconsistent with the terms of this Lease or other
existing leases or is otherwise not suitable for a first class office building;

                  (iii)    That the nature of the prospective transferee's
proposed or likely use of the Premises would involve any increased risk of the
use, release or mishandling of hazardous materials;

                  (iv)     That the prospective transferee is not likely to
conduct on the Property a business of a nature substantially equal to that
conducted by Tenant or other tenants on the Property;

                  (v)      That Landlord has not received assurances acceptable
to Landlord in its sole discretion that all past due amounts owing from Tenant
to Landlord (if any) will be paid and all other defaults on the part of Tenant
(if any) will be cured prior to the effectiveness of the proposed transfer.

         If Landlord withholds its consent to the proposed transfer pursuant to
Section 17.2(i), and if Tenant shall so request in writing, Landlord shall
provide to Tenant a statement of the basis on which Landlord denied its consent
within a reasonable time, however, no greater than ten (10) days after the
receipt of Tenant's notice. Landlord and Tenant agree that Tenant shall have the
burden of proving that Landlord's consent to the proposed transfer was withheld
unreasonably, and that such burden may be satisfied if Landlord fails to provide
a statement of a reasonable basis for withholding its consent within a
reasonable time after Tenant's request therefor. Tenant acknowledges and agrees
that each of the rights of Landlord in the event of proposed transfer set forth
in this Article is a reasonable restriction on transfer for purposes of
California Civil Code Section 1951.4.

         17.4     TENANT'S OBLIGATIONS CONTINUING: No transfer within the scope
of this article, whether with or without Landlord's consent, will release Tenant
or change Tenant's primary liability to pay Rent and to perform all other
obligations of Tenant under this Lease. Landlord's acceptance of Rent from any
other person is not a waiver of any provision of this Section. If Tenant's
transferee defaults under this Lease, Landlord may proceed directly against
Tenant without pursuing remedies against the transferee. Landlord may consent to
subsequent assignments or modifications of this Lease by Tenant's transferee,
without noticing Tenant or obtaining its consent, and such action will not
relieve Tenant of its liability under this Lease.

         17.5     EXCESS RENTAL: With respect to any sublease entered into by
Tenant with Landlord's consent as herein provided, if the rent and other
compensation paid by the subtenant to Tenant under such sublease, and all
agreements and other instruments pertaining in any way thereto, exceeds the Rent
being paid by Tenant to Landlord computed on a square foot basis (i.e., the
amount by which the rent and other compensation being paid by the subtenant to
Tenant exceeds the Rent being paid by Tenant to Landlord under this Lease for
each square foot leased by such subtenant) then Landlord will be entitled to the
amount of such excess ("Excess Rent") and Tenant will pay to Landlord such
Excess Rent within five (5) days after receipt by Tenant of the same. If Tenant
receives any fee, bonus or other payment (whether payable in one or more
installments) from any assignee or sublessee as partial consideration for the
making of such sublease or assignment ("Bonus Payment"), the entire amount of
such Bonus Payment shall be paid over to Landlord as additional rent hereunder.
Notwithstanding the foregoing, Tenant shall be entitled to receive from any
Excess Rent or Bonus Payment otherwise required to be paid to the Landlord the
amount of out-of-pocket expenses actually incurred by Tenant for reasonable and
customary brokerage commissions, tenant improvements, non-monetary lease
concessions or other expenses in connection with sublease or assignment provided
Tenant delivers sufficient evidence of such expenses to Landlord.

         17.6     SECURITY INTEREST: Tenant immediately and irrevocably assigns
to Landlord as security for Tenant's obligations under this Lease all rent from
any subletting of all or a part of the Premises as permitted by this Lease, and
Landlord as assignee and as attorney-in-fact for Tenant, or a receiver for
Tenant appointed on Landlord's application, may collect such rent and apply it
toward Tenant's obligations under this Lease; except that, until the occurrence
of an event of default by Tenant, Tenant will have the right to collect such
rent.

         17.7     TRANSFER FEE: In the event Landlord consents to a sublease or
assignment hereunder, Tenant shall reimburse Landlord for all attorney's fees
incurred by Landlord in connection with review and preparation of documents in
connection with such sublease or assignment and will pay Landlord a reasonable
fee, not to exceed $250.00, for Landlord's processing of documents necessary to
the giving of such consent and/or assumption by the assignees.

                               ARTICLE 18. PARKING

         Tenant shall have the right to park automobiles in connection with its
use and occupancy of the Premises as more particularly described in the Addendum

         Tenant agrees upon the expiration or termination of this Lease,
immediately and peaceably to yield up and surrender the Premises, notice to quit
or vacate is hereby expressly waived. Tenant shall be liable to Landlord for any
and all damages incurred by Tenant as the result of any failure by Tenant,
timely, to surrender possession of the Premises as required herein. If Tenant
shall hold over after the expiration of this Lease for any cause, such holding
over shall be deemed a tenancy at sufferance or, at the sole discretion of
Landlord, a tenancy from month-to-month only, in which event such month-to-month
tenancy shall be upon the same terms, conditions and provisions as in this Lease
contained, at one hundred forty percent (140%) of the monthly Rent as was in
effect immediately prior to the termination.

         One or more waivers by Landlord of any breach of any covenant or
condition shall not be construed as a waiver of a subsequent or continuing
breach of the same or of any covenant or condition, and the consent or approval
by Landlord to any act by Tenant requiring Landlord's consent or approval shall
not be deemed to waive or render unnecessary Landlord's consent or approval to
or of any subsequent act. No waiver of any provision of this Lease shall be
deemed to have been made, unless it be in writing and signed by the party to be
charged therewith.

                      ARTICLE 22. LANDLORD'S RIGHT OF ENTRY

         Landlord and its agents may enter upon the Premises at any reasonable
time with prior notice, except in the event of emergencies, to post such notices
as Landlord may reasonably deem necessary to exempt Landlord and Landlord's
title from responsibility on account of any work or repairs done by Tenant upon
or in connection with the Premises; to inspect and examine the Premises and see
that the covenants hereof are being kept and performed; to make such repairs,
additions or improvements as Landlord shall deem necessary; or, to exhibit the
Premises to prospective lessees or purchasers thereof.

                         ARTICLE 23. TIME OF THE ESSENCE

         Time is expressly declared to be of the essence of this Lease, and of
all covenants and conditions herein contained.

                       ARTICLE 24. SUCCESSORS AND ASSIGNS

         The covenants and conditions herein contained shall, subject to the
provisions of Article 17 and this Article, apply to and bind the heirs,
successors, executors, administrators and assigns of the respective parties
hereof. If this Lease is signed by more than one person as Tenant, their
obligation shall be joint and several.

         Landlord may freely and fully assign its interest hereunder. The term
"Landlord" shall mean only the owner at the time in question of the Building or
of a lease of the Building, so that in the event of any transfer or transfers of
title to the Building or of Landlord's interest in a lease of the Building, the
transferor shall be and hereby is relieved and freed of all obligation of
Landlord under this Lease accruing after such transfer, and it shall be deemed,
without further agreement, that such transferee has assumed and agreed to
perform and observe all obligations of Landlord herein during the period it is
the holder of Landlord's interest under this Lease. Tenant shall attorn to and
recognize as its landlord under this Lease any transferee of the Building or
Landlord's interest hereunder. In any event, Tenant shall look only to
Landlord's estate and property in the Building and the land on which it is
located for satisfaction of Tenant's remedies for the collection of a judgment
(or other judicial process) requiring the payment of money by Landlord in the
event of any default by Landlord hereunder, and no other property or assets of
Landlord or its partners or principals, disclosed or undisclosed, shall be
subject to levy, execution or other enforcement procedure for the satisfaction
of Tenant's remedies under or with respect to this Lease, the relationship of
Landlord and Tenant hereunder or Tenant's use or occupancy of the Premises and
no such parties shall be named in any action or suit by Tenant against Landlord.

                            ARTICLE 25. BUILDING NAME

         Tenant shall not use the name of the Building or words to that effect
in connection with any business on the Premises without the written consent of
Landlord. Landlord may change the name of the Building at any time without
consent of or notice to Tenant.

                                ARTICLE 26. KEYS

         Two (2) keys to the Premises will be furnished to Tenant by Landlord.
Additional keys will be furnished upon Tenant paying Landlord the cost thereof.
No additional lock or locks shall be placed by Tenant on any door in the
Premises or Building unless written consent of Landlord shall have been first
obtained; and, should such consent be so obtained, Landlord shall be supplied
with keys to each such lock. Only the employees of Landlord or those it has
authorized in writing shall work on or modify any lock which is part of the
Premises. Tenant shall not cause or allow any keys to be possessed by any person
other than an authorized agent of Tenant. Tenant agrees, at the termination of
the tenancy, to return all keys of all doors and any security cards.

five (5) days prior written notice by Landlord, to execute, acknowledge and
deliver to Landlord, a statement in writing (i) certifying this Lease is
unmodified and in full force and effect, or, if there have been modifications,

         of this Lease, Tenant shall have a first right of negotiation on the
         terms and conditions described below on all available space on the
         first and second floors of the Building, subject to any existing
         renewal, expansion or similar rights of existing tenants. In the event
         Landlord receives an offer to lease any said available space, Landlord
         shall notify Tenant of such offer. If Tenant delivers written notice of
         Tenant's exercise of the right of first negotiation within five (5)
         business days after delivery of Landlord's notice, Landlord and Tenant
         shall meet and attempt negotiate in good faith terms which are
         acceptable to the parties, each in their sole and absolute discretion.
         If, within fifteen (15) days after Landlord's notice of an offer to

         expansion, Tenant's first right of negotiation on available space shall
         be of no further force or effect for said space and Landlord shall have
         the absolute right at any time thereafter to lease such space free of
         any rights of Tenant. If Tenant does not elect to exercise its first
         right of negotiation within five (5) business days after delivery of
         Landlord's notice, then Tenant's right of first negotiation shall be of
         no further force or effect as to such space and Landlord shall have the
         absolute right at any time thereafter to lease such space free of any
         rights of Tenant.

                              WORK LETTER AGREEMENT

         THIS WORK LETTER AGREEMENT is attached to and forms a part of that
certain Lease dated June 17,1996 (the "Lease"), by and between Williams

Companies ("Landlord") and HNC Software, Inc., a Delaware Corporation ("Tenant")
and relates to the construction of certain improvements ("Tenant Improvements")

terms not defined herein shall have the respective meanings set forth in the
Lease.

1.       TENANT IMPROVEMENT ALLOWANCE

         (a)      Landlord agrees to provide Tenant with the following tenant
improvement allowance (the "Tenant Improvement Allowance"): (i) Fifteen Dollars
($15) per rentable square foot within the portion of the Premises on the third
floor of the Building, or a total of Two Hundred Sixty-Five Thousand Six Hundred
Ninety-Five Dollars ($265,695), (ii) Twenty Dollars ($20) per usable square foot
within the portion of the Premises on the portion of the second floor of the
Building that is unimproved shell space, or a total of One Hundred Fifty-Six
Thousand Nine Hundred Sixty Dollars ($156,960), and (iii) Seven Dollars ($7) per
usable square foot for the portion of the Premises on the portion of the second
floor of the Building that has been previously improved, or a total of Thirty
Thousand Two Hundred Forty-Seven Dollars ($30,247). The allowances described in
clauses (i), (ii) and (iii) are specifically allocated to the applicable
portions of the Premises and may not be used for Tenant Improvements to any
other portion of the Premises, provided that Tenant may transfer up to five
percent (5%) of the amounts allocated in such clauses from one such portion of
the Premises to another. For example, Tenant may use not more than One Thousand
Five Hundred Twelve Dollars and Thirty-Five Cents ($1,512.35) of the allowance
for previously improved space on the second Door for Tenant Improvements to
other portions of the Premises. Any other transfers of the Tenant Improvement
Allowance from one portion of the Premises to another shall be subject to
Landlord's prior written approval. All soft costs including, but not limited to,
fees, contractor overhead, profit, processing, permits, architectural
engineering and reimbursables attributable directly or indirectly to the Tenant
Improvements shall be allocated between the portions of the Premises described
above based upon their proportional Tenant Improvement Allowance expenditures.

         (b)      The Tenant Improvement Allowance may be used to pay for the
construction by Landlord's Contractor (as defined below) of Tenant Improvements
permanently installed and incorporated into the realty of the Premises,
including costs of material and labor, fees for permits and licenses paid to any
governmental agency in connection with such construction, and other actual
out-of-pocket costs paid, directly or indirectly, by Landlord for such
construction, but specifically excluding payment for Tenant's fixtures,
furniture, cabling and other personal property, which shall be constructed and
installed at Tenant's sole cost and expense and in accordance with the
requirements of the Lease. Landlord shall not impose any charge upon the Tenant
Improvement Allowance for Landlord's profit, overhead or supervision of the
construction of the Tenant Improvements. Notwithstanding the foregoing, if
Landlord engages any consultants to review specialized or upgraded improvements
requested by Tenant, the reasonable costs incurred by Landlord shall be charged
against the Tenant Improvement Allowance.

         (c)      The Tenant Improvement Allowance may also be used to pay for
the services of the Space Planner (as defined below) to prepare the Space Plan
and the Plans and Specifications (as such terms are defined below) and to
provide construction administration, millwork plans and other space
planning/architectural services customarily provided for similar projects,
provided that the total amount of the Tenant Improvement Allowance that may be
used to pay the Space Planner shall not exceed One Dollar and Forty-Five Cents
($1.45) per usable square foot within the Premises ("Architectural Cap"). Tenant
shall be solely responsible for any fees or other amounts payable to the Space
Planner in excess of the Architectural Cap.

         (d)      Tenant shall be solely responsible for the cost of any Tenant
Improvements in excess of the Tenant Improvement Allowance (or in excess of the
portion of the Tenant Improvement Allowance allocated to each portion of the
Premises, subject to Tenant's limited right to reallocate such amounts as
described in (a) above), for the cost of any fees and costs of the Space Planner
in excess of the Architectural Cap and the cost of any decorating devices,
Tenant's fixtures, cabling, such as nonstandard items requested by Tenant to be
incorporated in the Tenant Improvements. Tenant shall pay to Landlord fifty
percent (50%) of any such excess cost upon presentation of an invoice to Tenant
and the remaining fifty percent (50%) upon Substantial Completion (as defined
below). Any such payments shall be collectible as additional obligations of
Tenant pursuant to the Lease and, in default of payment thereof, Landlord shall
(in addition to all other remedies) have the same rights as in the event of
default in payment of rent. Any portion of the Tenant Improvement Allowance that
is not used by Tenant upon Substantial Completion of the Tenant Improvements
shall be retained by Landlord and Tenant shall have no right or claim, then or
in the future, to any unused portion. The parties agree that the intent of the
Tenant Improvement Allowance is to cause to be constructed generic/building
standard Tenant Improvements throughout the Premises.

other laws.

         (c)      Landlord will disburse payments from the Tenant Improvement

or conditioned. If Landlord disapproves any Design Documents, Tenant shall cause
the Space Planner to deliver revised Design Documents to Landlord within ten
(10) days. Without limiting the foregoing, Landlord may withhold its approval of
any Design Documents which require work which:

                  (i)      exceeds or affects the structural integrity of the

Landlord for their completeness, design sufficiency, or compliance with laws,
rules, and regulations of governmental agencies or authorities and shall not
relieve Tenant of its obligations under Section 2(b). Landlord makes no warranty
or representation as to the adequacy, efficiency, performance or desirability of

from Tenant to Landlord on a form approved by Landlord. All such changes shall
be subject to Landlord's prior written approval. Tenant shall be solely
responsible for the cost of any such changes, and such costs shall be chargeable
against the Tenant Improvement Allowance provided Landlord consents to such
requested change. Prior to commencing any change, Landlord shall prepare and
deliver to Tenant, for Tenant's approval, a change order (the "Change Order")
setting forth the additional time required to perform the change and the total
cost of such change, which will include associated architectural, engineering

Contractor shall proceed to perform the change and Tenant shall pay for such
Change Order in accordance with Section 1 (d) above. Notwithstanding any minor
change order request(s), in the event Tenant substantially changes the scope of
work, Landlord reserves the right to charge a reasonable administration fee not
to exceed Forty and No/1 00ths ($40.00) Dollars per hour relating to the
administration of the change order(s). Upon Landlord's approval of change
orders, it shall state the fee, if applicable, and then Tenant shall pay

order. Change orders caused by existing conditions or unknown conditions shall
be excepted from Landlord's fees.

reasonable discretion based upon pricing, reputation and selection of
subcontractors and other factors Landlord deems relevant, and shall seek the
input of Tenant. Landlord will review with Tenant relevant contractor bids.

4.       CONSTRUCTION OF IMPROVEMENTS

         (a)      If the estimated cost ("Estimated Cost") to design and
construct the Tenant Improvements, including the Contractor's bid ("Bid
Amount"), is more than the amount of the Tenant Improvement Allowance, Landlord
shall notify Tenant in writing. Within three (3) business days following receipt
of such notice, Tenant shall either (i) agree in writing to pay the amount by

Specifications to reduce the Estimated Cost. The revised Plans and
Specifications shall not be rebid, but shall instead be provided to the
Contractor for Contractor to revise the Bid Amount. This procedure shall be
repeated until the Plans and Specifications, the Bid Amount and the Estimated
Cost have been approved by Tenant and Landlord, but all revisions of the Plans

necessary approvals and building permits. Upon receipt of the necessary
approvals and permits, Contractor shall begin construction of the Tenant
Improvements.

         (c)      Landlord shall furnish Tenant, as soon as is reasonably

5.       SUBSTANTIAL COMPLETION

         As used herein and in the Lease, the terms "Substantial Completion" or
"Substantially Complete" (or any other variant of such terms) with respect to
the Tenant Improvements shall mean that (i) the Premises have been approved to
occupy by the City of San Diego Building Inspection Department, and (ii) it has
been determined by a joint inspection of the Premises by a representative of the
Landlord and the Tenant that the Tenant Improvements have been constructed
substantially in accordance with the Plans and Specifications, except for
finishing details of construction, mechanical and other adjustments and other
items of the type commonly found on an architectural punch list, none of which
materially interfere with Tenant's use or occupancy of the Premises for Tenant's
intended normal business operation. Based on such joint inspection, Landlord
shall present to Tenant a Suite Acceptance Letter in Landlord's standard form
which Tenant shall promptly execute and deliver to Landlord. Any items of work
required by the Plans and Specifications and approved change order(s) that have
not been completed upon Substantial Completion shall be listed in the Suite
Acceptance Letter. Landlord shall promptly proceed to complete such items.

         If Substantial Completion is delayed as a result of (a) Tenant's
failure to comply with any time frames set forth herein or in the Lease, (b) any
changes to the approved Plans and Specifications requested by Tenant, (c)
Tenant's failure to furnish any documents required hereby, to approve any item
as required hereby or to perform any other act or obligation imposed on Tenant
by the Lease or this Work Letter as and when required, or (d) any other delay
caused by Tenant, its agents, employees or contractors (collectively, "Tenant
Delay"), then the Commencement Date and Tenant's obligation to pay Rent shall
begin on the date when Substantial Completion would have occurred but for the
Tenant Delay.

6.       AMERICANS WITH DISABILITIES ACT (ADA)/TITLE 24/CODE COMPLIANCE

         In order to establish a baseline, Landlord agrees that it will be
responsible at its sole cost for ensuring the compliance with applicable laws of
all existing unimproved areas and existing improvements within the common areas
of the Building and Premises, including all restrooms, corridors and access
areas. Landlord shall also be responsible for the cost of compliance with
applicable laws relating to areas affected by the Tenant Improvements to the
extent such Tenant Improvements are standard and generic, and such costs shall
not be charged against the Tenant Improvement Allowance. However, Tenant shall
be responsible for such cost of compliance, and such cost shall be charged
against the Tenant Improvement Allowance, to the extent the Tenant Improvements
(i) include special or upgraded improvements beyond those that are standard and
generic and trigger code compliance obligations for previously conforming areas
of the Building and (ii) require replacement and/or modification of the existing
fire rated corridors on floors two and three of the Building.

7.       UNAVOIDABLE DELAYS

         Performance by either party hereunder shall not be deemed to be in
default where delays or defaults are due to war, insurrection, strikes,
lock-outs, riots, floods, earthquakes, fires, casualties, acts of God, acts of
the public enemy, epidemics, quarantine restrictions, freight embargoes, lack of
transportation, governmental restrictions, moratoriums, third party litigation,
unusually severe weather, inability to secure necessary labor, materials or
tools, delays of any contractor or subcontractor or supplier, acts of the other
party, acts or failure to act of any public, private or governmental agency or
entity or any other causes beyond the control or without the fault of the party
claiming an extension of time to perform ("Unavoidable Delays").
