          (a)  Interest Rates.
               --------------

               (i)  Advances. Except as set forth in Section 2.3(b), the
                    --------
Advances shall bear interest, on the outstanding daily balance thereof, at a
rate equal to One Percent (1.0%) above the Prime Rate.

               (ii) Term Advances.  Except as set forth in Section 2.3(b), the
                    -------------
Term Advances shall bear interest, on the outstanding daily balance thereof, at
a rate equal to One and One Half Percent (1.5%) above the Prime Rate.

          (b)  Late Fee; Default Rate. If any payment is not made within ten

(10) days after the date such payment is due, Borrower shall pay Bank a late fee
equal to the lesser of (i) five percent (5%) of the amount of such unpaid amount
or (ii) the maximum amount permitted to be charged under applicable law. All
Obligations shall bear interest, from and after the occurrence and during the
continuance of an Event of Default, at a rate equal to five (5) percentage
points above the interest rate applicable immediately prior to the occurrence of
an Event of Default.

          (c)  Payments. Interest hereunder shall be due and payable on the

first calendar day of each month during the term hereof. Bank shall, at its
option, charge such interest, all Bank Expenses, and all Periodic Payments
against any of Borrower's deposit accounts or against the Committed Revolving
Line, in which case those amounts shall thereafter accrue interest at the rate
then applicable hereunder. Any interest not paid when due shall be compounded by
becoming a part of the Obligations, and such interest shall thereafter accrue
interest at the rate then applicable hereunder. Bank shall deliver to Borrower
statements of account in the ordinary course of business reflecting charges made
hereunder.

                                       9
<PAGE>

          (d)  Computation. In the event the Prime Rate is changed from time to
               -----------
time hereafter, the applicable rate of interest hereunder shall be increased or
decreased effective as of the day the Prime Rate is changed, by an amount equal
to such change in the Prime Rate. All interest chargeable under the Loan
Documents shall be computed on the basis of a three hundred sixty (360) day year
for the actual number of days elapsed.

     2.4  Crediting Payments.  Prior to the occurrence of an Event of Default,
          ------------------
Bank shall credit a wire transfer of funds, check or other item of payment to
such deposit account or Obligation as Borrower specifies. After the occurrence
of an Event of Default, the receipt by Bank of any wire transfer of funds,
check, or other item of payment shall be immediately applied to conditionally
reduce Obligations, but shall not be considered a payment on account unless such
payment is of immediately available federal funds or unless and until such check
or other item of payment is honored when presented for payment. Notwithstanding
anything to the contrary contained herein, any wire transfer or payment received
by Bank after 12:00 noon Pacific time shall be deemed to have been received by
Bank as of the opening of business on the immediately following Business Day.
Whenever any payment to Bank under the Loan Documents would otherwise be due
(except by reason of acceleration) on a date that is not a Business Day, such
payment shall instead be due on the next Business Day, and additional fees or
interest, as the case may be, shall accrue and be payable for the period of such
extension.

     2.5  Fees. Borrower shall pay to Bank the following:
          ----

          (a)  Facility Fee. On the Closing Date, a Facility Fee equal to
               ------------

after the Closing Date, all Bank Expenses, including reasonable attorneys' fees
and expenses, as and when they become due.

          2.6  Term. This Assignment shall become effective on the Closing Date
               ----
and, subject to Section 12.7, shall continue in full force and effect for a term
ending on the Term Maturity Date. Notwithstanding the foregoing, Bank shall have
the right to terminate its obligation to make Credit Extensions under this
Agreement immediately and without notice upon the occurrence and during the
continuance of an Event of Default. Notwithstanding termination, Bank's Lien on
the Collateral shall remain in effect for so long as any Obligations are
outstanding.

     3.   CONDITIONS OF LOANS.

               ------------------------------
performance of the Loan Documents are within Borrower's powers, have been duly
authorized, and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Certificate of Incorporation or Bylaws, nor
will they constitute an event of default under any material agreement to which
Borrower is a party or by which Borrower is bound. Borrower is not in default
under any agreement to which it is a party or by which it is bound, which
default could have a Material Adverse Effect.

          5.3  No Prior Encumbrances.  Borrower has good and indefeasible title
               ---------------------

Subsidiary need not make any payment if the amount or validity of such payment
is contested in good faith, by appropriate proceedings and is reserved against

          (a)  Borrower, at its expense, shall keep the Collateral insured

additional insured, and shall specify that the insurer must give at least twenty

request, Borrower shall deliver to Bank certified copies of such policies of
insurance and evidence of the payments of all premium therefor. All proceeds
over $50,000 payable under any such policy shall, at the option of Bank, be

applicable, those intellectual property rights listed on Exhibits A, B and C to
the Intellectual Property Security Agreement delivered to Bank by Borrower in
connection with this Agreement within thirty (30) days of the date of this

major revisions or additions to the intellectual property rights listed on such
Exhibits A, B and C.

continuing. Bank shall have the right, but not the obligation, to take, at
Borrower's sole expense, any actions that Borrower is required under this
Section to take but which Borrower fails to take, after fifteen (15) days'

reasonable costs and reasonable expenses incurred in the reasonable exercise of
its rights under this Section.

Extensions, Borrower will not do any of the following without Bank's prior
written consent, which Bank may grant or withhold in its sole discretion:

          7.1  Dispositions. Convey, sell, lease, transfer or otherwise dispose

          7.3  Mergers or Acquisitions. Merge or consolidate, or permit any of

organization, or acquire, or permit any of its Subsidiaries to acquire, all or
substantially all of the capital stock or property of another Person in any
transaction involving consideration of more than $100,000; provided, however,
that Borrower or any Subsidiary may merge, consolidate or reorganize with or
into another entity as long as Borrower or such Subsidiary is the surviving
corporation and an Event of Default does not exist before or after giving effect
to such transaction.

          7.4  Indebtedness.  Create, incur, assume or be or remain liable with
               ------------

or permit to exist any material transaction with any Affiliate of Borrower

upon fair and reasonable terms that are no less favorable to Borrower than would
be obtained in an arm's length transaction with a nonaffiliated Person.

          7.9  Subordinated Debt. Make any payment in respect of any
               -----------------
Subordinated Debt, or permit any of its Subsidiaries to make any such payment,

provision contained in any documentation relating to the Subordinated Debt
without Bank's prior written consent.

          7.10 Inventory. Store the Inventory with a bailee, warehouseman, or
               ---------
similar party unless Bank has received a pledge of the warehouse receipt
covering such Inventory; provided, however, that Borrower may deposit software
code in escrow for customers in the ordinary course of business. Except for
Inventory sold in the ordinary course of business and except for such other
locations as Bank may approve in writing, Borrower shall keep the Inventory only
at the location set forth in Section 10 hereof and such other locations of which
Borrower gives Bank prior written notice and as to which Borrower signs and
files a financing statement where needed to perfect Bank's security interest.

          7.11 Compliance. Become an "investment company" or be controlled by
               ----------
an "investment company," within the meaning of the Investment Company Act of
1940, or become

<PAGE>

principally engaged in, or undertake as one of its important activities, the
business of extending credit for the purpose of purchasing or carrying margin
stock, or use the proceeds of any Credit Extension for such purpose. Fail to
meet the minimum funding requirements of ERISA, permit a Reportable Event or
Prohibited Transaction, as defined in ERISA, to occur, fail to comply with the
Federal Fair Labor Standards Act or violate any law or regulation, which
violation could have a Material Adverse Effect or a material adverse effect on
the Collateral or the priority of Bank's Lien on the Collateral, or permit any
of its Subsidiaries to do any of the foregoing.

     8.   EVENTS OF DEFAULT.
          -----------------

          Any one or more of the following events shall constitute an Event of
Default by Borrower under this Agreement:

          8.1  Payment Default. If Borrower fails to pay, when due, any of the
               ---------------
Obligations;

          8.2  Covenant Default.  If Borrower fails to perform any obligation
               ----------------
under Article 6 or violates any of the covenants contained in Article 7 of this
Agreement, or fails or neglects to perform, keep, or observe any other material
term, provision, condition, covenant, or agreement contained in this Agreement,
in any of the Loan Documents, or in any other present or future written
agreement between Borrower and Bank and as to any default under such other term,
provision, condition, covenant or agreement that can be cured, has failed to
cure such default within thirty (30) days after Borrower receives written notice
thereof or any officer of Borrower becomes aware thereof; provided, however,
that if the default cannot by its nature be cured within the thirty (30) day
period or cannot after diligent attempts by Borrower be cured within such thirty
(30) day period, and such default is likely to be cured within a reasonable
time, then Borrower shall have an additional reasonable period (which shall not
in any case exceed forty-five (45) days) to attempt to cure such default, and
within such reasonable time period the failure to have cured such default shall
not be deemed an Event of Default (provided that no Credit Extensions will be
required to be made during such cure period);

          8.3  Material Adverse Change.  If there occurs a Material Adverse
               -----------------------
Effect;

          8.4  Attachment. If any material portion of the Collateral is
               ----------
attached, seized, subjected to a writ or distress warrant, or is levied upon, or
comes into the possession of any trustee, receiver or person acting in a similar
capacity and such attachment, seizure, writ or distress warrant or levy has not
been removed, discharged or rescinded within twenty (20) days, or if Borrower is
enjoined, restrained, or in any way prevented by court order from continuing to
conduct all or any material part of its business affairs, or if a judgment or
other claim becomes a lien or encumbrance upon any material portion of the
Collateral, or if a notice of lien, levy, or assessment is filed of record with
respect to any of the Collateral by the United States Government, or any
department, agency, or instrumentality thereof, or by any state, county,
municipal, or governmental agency, and the same is not paid within twenty (20)
days after Borrower receives notice thereof, provided that none of the foregoing
shall constitute an Event of Default where such action or event is stayed or an
adequate bond has been posted pending a good faith contest by Borrower (provided
that no Credit Extensions will be required to be made during such cure period);

          8.5  Insolvency. If Borrower becomes insolvent, or if an Insolvency
               ----------
Proceeding is commenced by Borrower, or if an Insolvency proceeding is commenced
against Borrower and is not dismissed or stayed within thirty (30) days
(provided that no Credit Extensions will be made prior to the dismissal of such
Insolvency Proceeding);

                                       18
<PAGE>

          8.6  Other Agreements. If there is a default in any agreement to which
               ----------------
Borrower is a party with a third party or parties resulting in a right by such
third party or parties, whether or not exercised, to accelerate the maturity of
any Indebtedness in an amount in excess of One Hundred Thousand Dollars
($100,000) or that could have a Material Adverse Effect;

          8.7  Subordinated Debt.  If Borrower makes any payment on account of

writing by Bank;

          8.8  Judgments. If a judgment or judgments for the payment of money
               ---------
in an amount, individually or in the aggregate, of at least One Hundred Thousand
Dollars ($100,000) shall be rendered against Borrower and shall remain
unsatisfied and unstayed for a period of thirty (30) days (provided that no
Credit Extensions will be made prior to the satisfaction or stay of such
judgment); or

          8.9  Misrepresentations. If any material misrepresentation or
               ------------------
material misstatement exists now or hereafter in any warranty or representation
set forth herein or in any certificate delivered to Bank by any Responsible
Officer pursuant to this Agreement or to induce Bank to enter into this
Agreement or any other Loan Document.

     9.   BANK'S RIGHTS AND REMEDIES.
          --------------------------

          9.1  Rights and Remedies. Upon the occurrence and during the
               -------------------
continuance of an Event of Default, Bank may, at its election, without notice of
its election and without demand, do any one or more of the following, all of
which are authorized by Borrower:

               (a)  Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8.5 all Obligations shall become immediately due and payable without any
action by Bank);

               (b)  Cease advancing money or extending credit to or for the
benefit of Borrower under this Agreement or under any other agreement between
Borrower and Bank;

               (c)  Settle or adjust disputes and claims directly with account
debtors for amounts, upon terms and in whatever order that Bank reasonably
considers advisable;

               (d)  Make such payments and do such acts as Bank considers
necessary or reasonable to protect its security interest in the Collateral.
Borrower agrees to assemble the Collateral if Bank so requires, and to make the
Collateral available to Bank as Bank may designate. Borrower authorizes Bank to
enter the premises where the Collateral is located, to take and maintain
possession of the Collateral, or any part of it, and to pay, purchase, contest,
or compromise any encumbrance, charge, or lien which in Bank's determination
appears to be prior or superior to its security interest and to pay all expenses
incurred in connection therewith. With respect to any of Borrower's owned
premises, Borrower hereby grants Bank a license to enter into possession of such
premises and to occupy the same, without charge, in order to exercise any of
Bank's rights or remedies provided herein, at law, in equity, or otherwise;

               (e)  Set off and apply to the Obligations any and all (i)
balances and deposits of Borrower held by Bank, or (ii) indebtedness at any time
owing to or for the credit or the account of Borrower held by Bank;

                                       19
<PAGE>

               (f)  Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Bank is hereby granted a license or other right, solely
pursuant to the provisions of this Section 9.1, to use, without charge,
Borrower's labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section 9.1, Borrower's
rights under all licenses and all franchise agreements shall inure to Bank's
benefit;

               (g)  Sell the Collateral at either a public or private sale, or
both, by way of one or more contracts or transactions, for cash or on terms, in
such manner and at such places (including Borrower's premises) as Bank
determines is commercially reasonable, and apply any proceeds to the Obligations
in whatever manner or order Bank deems appropriate;

               (h)  Bank may credit bid and purchase at any public sale; and

               (i)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

          9.2  Power of Attorney.  Effective only upon the occurrence and
               -----------------
during the continuance of an Event of Default, Borrower hereby irrevocably
appoints Bank (and any of Bank's designated officers, or employees) as
Borrower's true and lawful attorney to: (a) send requests for verification of
Accounts or notify account debtors of Bank's security interest in the Accounts;
(b) endorse Borrower's name on any checks or other forms of payment or security
that may come into Bank's possession; (c) sign Borrower's name on any invoice or
bill of lading relating to any Account, drafts against account debtors,
schedules and assignments of Accounts, verifications of Accounts, and notices to
account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all
claims under and decisions with respect to Borrower's policies of insurance; and
(f) settle and adjust disputes and claims respecting the accounts directly with
account debtors, for amounts and upon terms which Bank determines to be
reasonable; provided Bank may exercise such power of attorney to sign the name
of Borrower on any of the documents described in Section 4.2 regardless of
whether an Event of Default has occurred. The appointment of Bank as Borrower's
attorney in fact, and each and every one of Bank's rights and powers, being
coupled with an interest, is irrevocable until all of the Obligations have been
fully repaid and performed and Bank's obligation to provide advances hereunder
is terminated.

          9.3  Accounts Collection. Upon the occurrence and during the
               -------------------
continuance of an Event of Default, Bank may notify any Person owing funds to
Borrower of Bank's security interest in such funds and verify the amount of such
Account. Borrower shall collect all amounts owing to Borrower for Bank, receive
in trust all payments as Bank's trustee, and immediately deliver such payments
to Bank in their original form as received from the account debtor, with proper
endorsements for deposit.

          9.4  Bank Expenses. If Borrower fails to pay any amounts or furnish
               -------------
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following
after reasonable notice to Borrower: (a) make payment of the same or any part
thereof; (b) set up such reserves under the Revolving Facility as Bank deems
necessary to protect Bank from the exposure created by such failure; or (c)
obtain and maintain insurance policies of the type discussed in Section 6.6 of
this Agreement, and take any action with respect to such policies as Bank deems
prudent. Any amounts so paid or deposited by Bank shall constitute Bank
Expenses,

                                       20
<PAGE>

shall be immediately due and payable, and shall bear interest at the then
applicable rate hereinabove provided, and shall be secured by the Collateral.
Any payments made by Bank shall not constitute an agreement by Bank to make
similar payments in the future or a waiver by Bank of any Event of Default under
this Agreement.

          9.5  Bank's Liability for Collateral. So long as Bank complies with
               -------------------------------
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever. All risk of
loss, damage or destruction of the Collateral shall be borne by Borrower.

          9.6  Remedies Cumulative.  Bank's rights and remedies under this
               -------------------
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

          9.7  Demand; Protest.  Borrower waives demand, protest, notice of
               ---------------
protest, notice of default or dishonor, notice of payment and nonpayment, notice
of any default, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Bank on which Borrower may in any way be liable.

     10.  NOTICES.

retired Judge of the Court selected by mutual agreement of the parties, and if

<PAGE>

any time after thirty (30) days following notice to any other party of the
nature of the controversy, dispute or claim, by filing a petition for a hearing
and/or trial, All discovery permitted by this Agreement shall be completed no
later than fifteen (15) days before the first hearing date established by the
referee. The referee may extend such period in the event of a party's refusal to

illness. No party shall be entitled to "priority" in conducting discovery.
Dispositions may be taken by either party upon seven (7) days written notice,
and request for production or inspection of documents which cannot be resolved
by the parties shall be submitted to the referee as provided herein. The
Superior Court is empowered to issue temporary and/or provisions remedies, as
appropriate.

          (b)  Except as expressly set forth in this Agreement, the referee
shall determine the manner in which the reference proceeding is conducted
including the time and place of all hearings, the order of presentation of
evidence, and all other questions that arise with respect to the course of the
reference proceeding. All proceedings and hearings conducted before the referee,
except for trial, shall be conducted without a court reporter except that when
any party so requests, a court reporter will be used at any hearing conducted

          (c)  The referee shall be required to determine all issues in

temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties. The referee shall issue a single judgment at the close
of the reference proceeding which shall dispose of all of the claims of the
parties that are the subject of the reference. The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee. The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a difficult
judgment, which new trial, if granted, is also to be a reference proceeding

          (d)  In the event that the enabling legislation which provides for
appointment of a referee is repealed (and no successor statute is enacted), any
dispute between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration. The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, (S)1280 through (S)1294.2 of the CCP as
amended from time to time. The limitations with respect to discovery as set
forth hereinabove shall apply to any such arbitration proceeding.

     14.  CONFIDENTIALLY.
          --------------

          In handling any confidential information Bank shall exercise the same
degree of care that it exercises with respect to its own proprietary information

(iv) as may be required in connection with the examination, audit or similar
investigation of Bank and (v) as Bank may determine in connection with the
enforcement of any remedies hereunder. Confidential information hereunder shall
not include information that either: (a) is in the public domain or in the
knowledge or possession of Bank when disclosed to Bank, as evidenced by Bank's
records in existence at the time of such disclosure, or becomes part of the

disclosed to Bank by a third party, provided Bank does not have actual knowledge
that such third party is prohibited from disclosing such information and
provided such disclosure is not otherwise in violation of Borrower's rights.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed as of the date first above written.

                                    RECITALS
                                    --------

     Borrower and Bank are parties to that certain Loan and Security Agreement
dated as of July 15; 1998, as amended (the "Agreement"). The parties desire to
amend the Agreement in accordance with the terms of this Amendment and waive
compliance with certain provisions thereof.

     NOW, THEREFORE, the parties agree as follows:

     1.   Waivers

     A.   Bank waives Borrower's obligations to comply with Section 6.8 for the
calendar month ending December 31, 1998. Bank does not waive such obligations
for any other dates or any other failure by Borrower to perform its obligations
under the Loan Documents. This waiver is not a continuing waiver with respect to
any failure to perform any obligation after the date of this Amendment and the
Bank hereby reserves all rights and remedies it may have upon such occurrence.

     B.   Bank waives Borrower's obligations to comply with Section 6.10 for the
calendar month ending December 31, 1998. Bank does not waive such obligations
for any other dates or any other failure by Borrower to perform its obligations
under the Loan Documents. This waiver is not a continuing waiver with respect to
any failure to perform any obligation after the date of this Amendment and the
Bank hereby reserves all rights and remedies it may have upon such occurrence.

     2.   Amendments.

       A. A new Section 5.16 is added to the Agreement as follows:

          "5.16  Year 2000 Problem. Borrower and its subsidiaries have the areas
                 -----------------
       within their operations and business which could be adversely affected
       by, and have developed or are developing a program to address on a timely
       basis, the Year 2000 Problem and have made related appropriate inquiry of
       material suppliers and vendors, and based on such review and program, the
       Year 2000 Problem will not have a Material Adverse Effect upon its
       financial condition, operations or business as new conducted. "Year 2000
       Problem" means the possibility that any computer applications or
       equipment used by Borrower may be unable to recognize and properly
       perform date-sensitive functions involving certain dates prior to and any
       dates on or after December 31, 1999."

     B.   Section 6.9 is amended in full to read in as follows:

          "6.9  Borrower shall not suffer a loss for the fiscal quarter ended
     December 31, 1998 In excess of $1,600,000."

     C.   Section 6.11 is amended to read in full as follows:

          "6.11 Equity Infusion. Borrower shall receive not less than $5,000,000
     in cash proceeds from institutional venture capital investors acceptable to
     Bank from the sale of its Series B capital stock on or before January 22,
     1999."
<PAGE>

     D.   The second Section numbered 6.11, which is entitled Registration of
          Intellectual Property Rights in the Agreement is renumbered to 6.12
          and the current Section 6.12 which is entitled Further Assurances is
          renumbered to 6.13.

     E.   A new Section 6.14 is added to the Agreement as follows:

          "6.14  Year 2000 Compliance. Borrower shall perform all acts
                 --------------------
     reasonably necessary to ensure that (a) Borrower and any business in which
     Borrower holds a substantial interest, and (b) all customers, suppliers and
     vendors that are material to Borrower's business, become Year 2000
     Compliant in a timely manner. Such acts shall include, without limitation,
     performing a comprehensive review and assessment of all Borrower's systems
     and adopting a detailed plan, with itemized budget, for the remediation,
     monitoring and testing of such systems. As used in this paragraph, "Year
     2000 Compliant" shall mean, in regard to any entity, that all software,
     hardware, firmware, equipment, goods or systems utilized by or material to
     the business operations or financial condition of such entity, will
     properly perform date sensitive functions before, during and after the year
     2000. Borrower shell, immediately upon request, provide to Bank such
     certifications or other evidence of Borrower's compliance with the terms of
     this paragraph as Bank may from time to require."

     3.   Unless otherwise defined, all capitalized terms in this Amendment
shall be defined in the Agreement. Except as amended, the Agreement remains in
full force and effect.

     4.   Borrower represents and warrants that the Representations and
Warranties contained in the Agreement are true and correct as of the date of
this Amendment, and that no Event of Default has occurred and is continuing.

     5.   This Amendment may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one instrument.

     6.   As a condition to the effectiveness of this Amendment, Borrower shall
pay Bank a fee of $250.

IN WITNESS WHEREOF, the undersigned have executed this Amendment as of the first
date above written.
