Silicon Valley Bank

                          Loan and Security Agreement

Borrower:    HAHT Commerce, Inc.
Address:     400 Newton Road
             Raleigh, North Carolina  27615

Date:        October __, 2000

THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK,  COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California  95054 and the borrower(s) named
above (jointly and severally, the "Borrower"), whose chief executive office is
located at the above address ("Borrower's Address").  The Schedule to this
Agreement (the "Schedule") shall for all purposes be deemed to be a part of this
Agreement, and the same is an integral part of this Agreement.  (Definitions of
certain terms used in this Agreement are set forth in Section 8 below.)

1.   LOANS.

     1.1 Loans. Silicon will make loans to Borrower (the "Loans"), in amounts
determined by Silicon in its sole discretion, up to the amounts (the "Credit
Limit") shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing, and subject to deduction of any Reserves for accrued
interest and such other Reserves as Silicon deems proper from time to time.

     1.2 Interest. All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon. Regardless of the amount of
Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

     1.3 Overadvances. If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand. Without limiting Borrower's obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rate equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

     1.4 Fees. Borrower shall pay Silicon the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Silicon and are
not refundable.

     1.5 Letters of Credit. [Not Applicable]

2.   SECURITY INTEREST.

     2.1 Security Interest. To secure the payment and performance of all of the
Obligations when due, Borrower hereby grants to Silicon a security interest in
all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located: All Inventory, Equipment, Receivables, and
General Intangibles, including, without limitation, all of Borrower's Deposit
Accounts, and all money, and all property now or at any time in the future in
Silicon's possession (including claims and credit balances), and all proceeds
(including proceeds of any insurance policies, proceeds of proceeds and claims
against third parties), all products and all books and records related to any of
the foregoing (all of the foregoing, together with all other property in which
Silicon may now or in the future be granted a lien or security interest, is
referred to herein, collectively, as the "Collateral").

3.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

     In order to induce Silicon to enter into this Agreement and to make Loans,
Borrower represents and warrants to Silicon as follows, and Borrower covenants
that the following representations will continue to be true, and that Borrower
will at all times comply with all of the following covenants:

     3.1 Corporate Existence and Authority. Borrower, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower is and will continue
to be qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby

                                      -1-

     Silicon Valley Bank                   Loan and Security Agreement
--------------------------------------------------------------------------------

(i) have been duly and validly authorized, (ii) are enforceable against Borrower
in accordance with their terms (except as enforcement may be limited by
equitable principles and by bankruptcy, insolvency, reorganization, moratorium
or similar laws relating to creditors' rights generally), and (iii) do not
violate Borrower's articles or certificate of incorporation, or Borrower's
by-laws, or any law or any material agreement or instrument which is binding
upon Borrower or its property, and (iv) do not constitute grounds for
acceleration of any material indebtedness or obligation under any material
agreement or instrument which is binding upon Borrower or its property.

     3.2 Name; Trade Names and Styles. The name of Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days' prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

     3.3 Place of Business; Location of Collateral. The address set forth in the
heading to this Agreement is Borrower's chief executive office. In addition,
Borrower has places of business and Collateral is located only at the locations
set forth on the Schedule. Borrower will give Silicon at least 30 days prior
written notice before opening any additional place of business, changing its
chief executive office, or moving any of the Collateral to a location other than
Borrower's Address or one of the locations set forth on the Schedule.

     3.4 Title to Collateral; Permitted Liens. Borrower is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Borrower. The Collateral now is and will remain
free and clear of any and all liens, charges, security interests, encumbrances
and adverse claims, except for Permitted Liens. Silicon now has, and will
continue to have, a first-priority perfected and enforceable security interest
in all of the Collateral, subject only to the Permitted Liens, and Borrower will
at all times defend Silicon and the Collateral against all claims of others.
None of the Collateral now is or will be affixed to any real property in such a
manner, or with such intent, as to become a fixture. Borrower is not and will
not become a lessee under any real property lease pursuant to which the lessor
may obtain any rights in any of the Collateral and no such lease now prohibits,
restrains, impairs or will prohibit, restrain or impair Borrower's right to
remove any Collateral from the leased premises. Whenever any Collateral is
located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Borrower shall, whenever requested by Silicon, use its best efforts to cause
such third party to execute and deliver to Silicon, in form acceptable to
Silicon, such waivers and subordinations as Silicon shall specify, so as to
ensure that Silicon's rights in the Collateral are, and will continue to be,
superior to the rights of any such third party. Borrower will keep in full force
and effect, and will comply with all the terms of, any lease of real property
where any of the Collateral now or in the future may be located.

     3.5 Maintenance of Collateral. Borrower will maintain the Collateral in
good working condition *, and Borrower will not use the Collateral for any
unlawful purpose. Borrower will immediately advise Silicon in writing of any
material loss or damage to the Collateral.

     * (ordinary wear and tear excepted)

     3.6 Books and Records. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

     3.7 Financial Condition, Statements and Reports. All financial statements
now or in the future delivered to Silicon have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will completely and accurately reflect * the financial condition of
Borrower, at the times and for the periods therein stated. Between the last date
covered by any such statement provided to Silicon and the date hereof, there has
been no material adverse change in the financial condition or business of
Borrower. Borrower is now and will continue to be solvent.

     * in all material respects

     3.8 Tax Returns and Payments; Pension Contributions. Borrower has timely
filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all foreign, federal, state and local taxes, assessments, deposits and
contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.
Borrower shall, at all times, utilize the services of an outside payroll service
providing for the automatic deposit of all payroll taxes payable by Borrower.

     3.9 Compliance with Law. Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those
relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

     3.10 Litigation. Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any governmental agency (or any basis therefor known to Borrower) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform Silicon in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of

     * $150,000

     ** $300,000

     3.11 Use of Proceeds. All proceeds of all Loans shall be used solely for
lawful business purposes. Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation U of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

4.   RECEIVABLES.

     4.1 Representations Relating to Receivables. Borrower represents and
warrants to Silicon as follows: Each Receivable with respect to which Loans are
requested by Borrower shall, on the date each Loan is requested and made, (i)
represent an undisputed bona fide existing unconditional obligation of the
Account Debtor created by the sale, delivery, and acceptance of goods or the
rendition of services in the ordinary course of Borrower's business, and (ii)
meet the Minimum Eligibility Requirements set forth in Section 8 below.

     4.2 Representations Relating to Documents and Legal Compliance. Borrower
represents and warrants to Silicon as follows: All statements made and all
unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be,
and all signatories and endorsers have the capacity to contract. All sales and
other transactions underlying or giving rise to each Receivable shall fully
comply with all applicable laws and governmental rules and regulations. All
signatures and endorsements on all documents, instruments, and agreements
relating to all Receivables are and shall be genuine, and all such documents,
instruments and agreements are and shall be legally enforceable in accordance
with their terms.

     4.3 Schedules and Documents relating to Receivables. Borrower shall deliver
to Silicon transaction reports and loan requests, schedules and assignments of
all Receivables, and schedules of collections, all on Silicon's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Silicon's security interest and other rights in all of
Borrower's Receivables, nor shall Silicon's failure to advance or lend against a
specific Receivable affect or limit Silicon's security interest and other rights
therein. Loan requests received after 12:00 Noon * will not be considered by
Silicon until the next Business Day. Together with each such schedule and
assignment, or later if requested by Silicon, Borrower shall furnish Silicon
with copies (or, at Silicon's request, originals) of all contracts, orders,
invoices, and other similar documents, and all original shipping instructions,
delivery receipts, bills of lading, and other evidence of delivery, for any
goods the sale or disposition of which gave rise to such Receivables, and
Borrower warrants the genuineness of all of the foregoing. Borrower shall also
furnish to Silicon an aged accounts receivable trial balance in such form and at
such intervals as Silicon shall request. In addition, Borrower shall deliver to
Silicon the originals of all instruments, chattel paper, security agreements,
guarantees and other documents and property evidencing or securing any
Receivables, immediately upon receipt thereof and in the same form as received,
with all necessary indorsements, all of which shall be with recourse. Borrower
shall also provide Silicon with copies of all credit memos within two days after
the date issued.

     * (California time)

     4.4 Collection of Receivables. Borrower shall have the right to collect all
Receivables, unless and until a Default or an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Silicon, and Borrower shall immediately deliver all such payments and proceeds
to Silicon in their original form, duly endorsed in blank, to be applied to the
Obligations in such order as Silicon shall determine. Silicon may, in its
discretion, require that all proceeds of Collateral be deposited by Borrower
into a lockbox account, or such other "blocked account" as Silicon may specify,
pursuant to a blocked account agreement in such form as Silicon may specify. *
Silicon or its designee may, at any time, notify Account Debtors that the
Receivables have been assigned to Silicon.

     * Upon the occurrence and during the continuation of an Event of Default,

     4.5. Remittance of Proceeds. All proceeds arising from the disposition of
any Collateral shall be delivered, in kind, by Borrower to Silicon in the
original form in which received by Borrower not later than the following
Business Day after receipt by Borrower, to be applied to the Obligations in such
order as Silicon shall determine; provided that, if no Default or Event of
Default has occurred *, Borrower shall not be obligated to remit to Silicon the
proceeds of the sale of worn out or obsolete equipment disposed of by Borrower
in good faith in an arm's length transaction for an aggregate purchase price of
$25,000 or less (for all such transactions in any fiscal year). Borrower agrees
that it will not commingle proceeds of Collateral with any of Borrower's other
funds or property, but will hold such proceeds separate and apart from such
other funds and property and in an express trust for Silicon. Nothing in this
Section limits the restrictions on disposition of Collateral set forth elsewhere
in this Agreement.

     * and is continuing

     4.6 Disputes. Borrower shall notify Silicon promptly of all disputes or
claims relating to Receivables.

     Silicon Valley Bank                      Loan and Security Agreement
--------------------------------------------------------------------------------

Borrower shall not forgive (completely or partially), compromise or settle any
Receivable for less than payment in full, or agree to do any of the foregoing,
except that Borrower may do so, provided that: (i) Borrower does so in good
faith, in a commercially reasonable manner, in the ordinary course of business,
and in arm's length transactions, which are reported to Silicon on the regular
reports provided to Silicon; (ii) no Default or Event of Default has occurred
and is continuing; and (iii) taking into account all such discounts settlements
and forgiveness, the total outstanding Loans will not exceed the Credit Limit.
Silicon may, at any time after the occurrence * of an Event of Default, settle
or adjust disputes or claims directly with Account Debtors for amounts and upon
terms which Silicon considers advisable in its reasonable credit judgment and,
in all cases, Silicon shall credit Borrower's Loan account with only the net
amounts received by Silicon in payment of any Receivables.

     * and during the continuation

     4.7 Returns. Provided no Event of Default has occurred and is continuing,
if any Account Debtor returns any Inventory to Borrower in the ordinary course
of its business, Borrower shall promptly determine the reason for such return
and promptly issue a credit memorandum to the Account Debtor in the appropriate
amount (sending a copy to Silicon). In the event any attempted return occurs
after the occurrence of any Event of Default, Borrower shall (i) hold the
returned Inventory in trust for Silicon, (ii) segregate all returned Inventory
from all of Borrower's other property, (iii) conspicuously label the returned
Inventory as Silicon's property, and (iv) immediately notify Silicon of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Silicon's request deliver such
returned Inventory to Silicon.

     4.8 Verification. Silicon may, from time to time, verify directly with the
respective Account Debtors the validity, amount and other matters relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Borrower or Silicon or such other name as Silicon may choose.

     4.9 No Liability. Silicon shall not under any circumstances be responsible
or liable for any shortage or discrepancy in, damage to, or loss or destruction
of, any goods, the sale or other disposition of which gives rise to a
Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Silicon be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable. Nothing herein shall, however, relieve Silicon from liability for
its own gross negligence or willful misconduct.

5.   ADDITIONAL DUTIES OF THE BORROWER.

     5.1 Financial and Other Covenants. Borrower shall at all times comply with
the financial and other covenants set forth in the Schedule.

     5.2 Insurance. Borrower shall, at all times insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Borrower shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance is, at all times, in
full force and effect. All such insurance policies shall name Silicon as an
additional loss payee, and shall contain a lenders loss payee endorsement in
form reasonably acceptable to Silicon. Upon receipt of the proceeds of any such
insurance, Silicon shall apply such proceeds in reduction of the Obligations as
Silicon shall determine in its sole discretion, except that, provided no Default
or Event of Default has occurred and is continuing, Silicon shall release to
Borrower insurance proceeds with respect to Equipment totaling less than
$100,000, which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid. Silicon may
require reasonable assurance that the insurance proceeds so released will be so
used. If Borrower fails to provide or pay for any insurance, Silicon may, but is
not obligated to, obtain the same at Borrower's expense. Borrower shall promptly
deliver to Silicon copies of all reports made to insurance companies.

     5.3 Reports. Borrower, at its expense, shall provide Silicon with the
written reports set forth in the Schedule, and such other written reports with
respect to Borrower (including budgets, sales projections, operating plans and
other financial documentation), as Silicon shall from time to time reasonably
specify.

     5.4 Access to Collateral, Books and Records. At reasonable times, and on
one Business Day's notice, Silicon, or its agents, shall have the right to
inspect the Collateral, and the right to audit and copy Borrower's books and
records. Silicon shall take reasonable steps to keep confidential all
information obtained *, but Silicon shall have the right to disclose any such
information to its auditors, regulatory agencies, and attorneys, and pursuant to
any subpoena or other legal process. The foregoing inspections and audits shall
be at Borrower's expense and the charge therefor shall be $600 per person per
day (or such higher amount as shall represent Silicon's then current standard
charge for the same), plus reasonable out of pocket expenses. Borrower will not
enter into any agreement with any accounting firm, service bureau or third party
to store Borrower's books or records at any location other than Borrower's
Address, without first obtaining Silicon's written consent, which may be
conditioned upon such accounting firm, service bureau or other third party
agreeing to give Silicon the same rights with respect to access to books and
records and related rights as Silicon has under this Loan Agreement. Borrower
waives the benefit of any accountant-client privilege or other evidentiary
privilege precluding or limiting the disclosure, divulgence or delivery of any
of its books and records (except that Borrower does not waive any attorney-
client privilege).

Borrower shall not, without Silicon's prior written consent, do any of the

business *; (iii) enter into any other transaction outside the ordinary course
of business; (iv) sell or transfer any Collateral, except for the sale of
finished Inventory in the ordinary course of Borrower's business, and except for
the sale of obsolete or unneeded Equipment in the ordinary course of business;
(v) store any Inventory or other Collateral with any warehouseman or other third
party; (vi) sell any Inventory on a sale- or-return, guaranteed sale,
consignment, or other contingent basis; (vii) make any loans of any money or
other assets **; (viii) incur any debts, outside the ordinary course of
business, which would have a material, adverse effect on Borrower or on the
prospect of repayment of the Obligations; (ix) guarantee or otherwise become
liable with respect to the obligations of another party or entity; (x) pay or
declare any dividends on Borrower's stock (except for dividends payable solely
in stock of Borrower); (xi) redeem, retire, purchase or otherwise acquire,
directly or indirectly, any of Borrower's stock; (xii) make any change in
Borrower's capital structure which would have a material adverse effect on
Borrower or on the prospect of repayment of the Obligations; or (xiii) pay total
compensation, including salaries, fees, bonuses, commissions, and all other
payments, whether directly or indirectly, in money or otherwise, to Borrower's
executives, officers and directors (or any relative thereof) in an amount in

dissolve. Transactions permitted by the foregoing provisions of this Section are
only permitted if no Default or Event of Default would occur as a result of such
transaction.

     * and except for the Permitted HAHT Australia Transaction

     ** ; provided, however, that, so long as no Default or Event of Default has
          --------  -------
occurred and is continuing, Borrower may make loans to Guarantor in an aggregate
amount not to exceed $500,000 at any one time outstanding and subject to the
subordination agreement in respect thereof referenced in Section 9 of the
Schedule

     5.6 Litigation Cooperation. Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Silicon, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Silicon may deem them reasonably necessary in order
to prosecute or defend any such suit or proceeding.

     5.7 Further Assurances. Borrower agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon, may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

6.   TERM.

     6.1 Maturity Date. This Agreement shall continue in effect until the
maturity date set forth on the Schedule (the "Maturity Date"), subject to
Section 6.3 below.

     6.2 Early Termination. This Agreement may be terminated prior to the
Maturity Date as follows: (i) by Borrower, effective three Business Days after
written notice of termination is given to Silicon; or (ii) by Silicon at any
time after the occurrence * of an Event of Default, without notice, effective
immediately. If this Agreement is terminated by Borrower or by Silicon under
this Section 6.2, Borrower shall pay to Silicon a termination fee in an amount
equal to ** of the Maximum Credit Limit, provided that no
termination fee shall be charged if the credit facility hereunder is replaced
with a new facility from another division of Silicon Valley Bank. The
termination fee shall be due and payable on the effective date of termination
and thereafter shall bear interest at a rate equal to the highest rate
applicable to any of the Obligations.

     * and during the continuation

     ** one percent (1.0%)

     6.3 Payment of Obligations. On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such Obligations are otherwise then due and payable.
Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Silicon, Silicon may, in its sole discretion, refuse to make any further Loans
after termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Silicon's security interests.

when due any Loan or any interest thereon or any other monetary Obligation; or

     *** and is continuing

     7.2 Remedies. Upon the occurrence of any Event of Default, and at any time
thereafter *, Silicon, at its option, and without notice or demand of any kind
(all of which are hereby expressly waived by Borrower), may do any one or more
of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by
any instrument evidencing or relating to any Obligation; (c) Take possession of
any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of

cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other

charge; (f) Sell, lease or otherwise dispose of any of the Collateral, in its
condition at the time Silicon obtains possession of it or after further
manufacturing,

processing or repair, at one or more public and/or private sales, in lots or in
bulk, for cash, exchange or other property, or on credit, and to adjourn any
such sale from time to time without notice other than oral announcement at the
time scheduled for sale. Silicon shall have the right to conduct such
disposition on Borrower's premises without charge, for such time or times as
Silicon deems reasonable, or on Silicon's premises, or elsewhere and the
Collateral need not be located at the place of disposition. Silicon may directly
or through any affiliated company purchase or lease any Collateral at any such
public disposition, and if permissible under applicable law, at any private
disposition. Any sale or other disposition of Collateral shall not relieve
Borrower of any liability Borrower may have if any Collateral is defective as to
title or physical condition or otherwise at the time of sale; (g) Demand payment
of, and collect any Receivables and General Intangibles comprising Collateral
and, in connection therewith, Borrower irrevocably authorizes Silicon to endorse

therefrom payments made with respect to any item of the Collateral or proceeds
thereof, and, in Silicon's sole discretion, to grant extensions of time to pay,

attorneys' fees, expenses, costs, liabilities and obligations incurred by

Obligations, shall be due on demand, and shall bear interest at a rate equal to
the highest interest rate applicable to any of the Obligations. Without limiting
any of Silicon's rights and remedies, from and after the occurrence ** of any
Event of Default, the interest rate applicable to the Obligations shall be
increased by an additional four percent per annum.

     * during the continuation thereof

     ** and during the continuation thereof

     7.3 Standards for Determining Commercial Reasonableness. Borrower and
Silicon agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to
Borrower at least seven days prior to the sale, and, in the case of a public
sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be
conducted; (ii) Notice of the sale describes the collateral in general, non-
specific terms; (iii) The sale is conducted at a place designated by Silicon,
with or without the Collateral being present; (iv) The sale commences at any
time between 8:00 a.m. and 6:00 p.m; (v) Payment of the purchase price in cash
or by cashier's check or wire transfer is required; (vi) With respect to any
sale of any of the Collateral, Silicon may (but is not obligated to) direct any
prospective purchaser to ascertain directly from Borrower any and all
information concerning the same. Silicon shall be free to employ other methods
of noticing and selling the Collateral, in its discretion, if they are
commercially reasonable.

     7.4 Power of Attorney. Upon the occurrence * of any Event of Default,
without limiting Silicon's other rights and remedies, Borrower grants to Silicon
an irrevocable power of attorney coupled with an interest, authorizing and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without obligation, with or without notice to
Borrower, and at Borrower's expense, to do any or all of the following, in
Borrower's name or otherwise, but Silicon agrees to exercise the following
powers in a commercially reasonable manner: (a) Execute on behalf of Borrower
any documents that Silicon may, in its sole discretion, deem advisable in order
to perfect and maintain Silicon's security interest in the Collateral, or in
order to exercise a right of Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of Borrower any document
exercising, transferring or assigning any option to purchase, sell or otherwise
dispose of or to lease (as lessor or lessee) any real or personal property which
is part of Silicon's Collateral or in which Silicon has an interest; (c) Execute
on behalf of Borrower, any invoices relating to any Receivable, any draft
against any Account Debtor and any notice to any Account Debtor, any proof of
claim in bankruptcy, any Notice of Lien, claim of mechanic's, materialman's or
other lien, or assignment or satisfaction of mechanic's, materialman's or other
lien; (d) Take control in any manner of any cash or non-cash items of payment or
proceeds of Collateral; endorse the name of Borrower upon any instruments, or
documents, evidence of payment or Collateral that may come into Silicon's
possession; (e) Endorse all checks and other forms of remittances received by
Silicon; (f) Pay, contest or settle any lien, charge, encumbrance, security
interest and adverse claim in or to any of the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; (g)
Grant extensions of time to pay, compromise claims and settle Receivables and
General Intangibles for less than face value and execute all releases and other
documents in connection therewith; (h) Pay any sums required on account of
Borrower's taxes or to secure the release of any liens therefor, or both; (i)
Settle and adjust, and give releases of, any insurance claim that relates to any
of the Collateral and obtain payment therefor; (j) Instruct any third party
having custody or control of any books or records belonging to, or relating to,
Borrower to give Silicon the same rights of access and other rights with respect
thereto as Silicon has under this Agreement; and (k) Take any action or pay any
sum required of Borrower pursuant to this Agreement and any other present or
future agreements. Any and all reasonable sums paid and any and all reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon with respect to the foregoing shall be added to and become part of the
Obligations, shall be payable on demand, and shall bear interest at a rate equal
to the highest interest rate applicable to any of the Obligations. In no event
shall Silicon's rights under the foregoing power of attorney or any of Silicon's
other rights under this Agreement be deemed to indicate that Silicon is in
control of the business, management or properties of Borrower.

     * and during the continuation thereof

     7.5 Application of Proceeds. All proceeds realized as the result of any
sale of the Collateral shall be applied by Silicon first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon in the exercise of its rights under this Agreement, second to the
interest due upon any of the Obligations, and third to the principal of the
Obligations, in such order as Silicon shall determine in its sole discretion.
Any surplus shall be paid to Borrower or other persons legally entitled thereto;
Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

     7.6 Remedies Cumulative. In addition to the rights and remedies set forth
in this Agreement, Silicon shall have all the other rights and remedies accorded
a secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

9.   GENERAL PROVISIONS.

     9.1 Interest Computation. In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by Silicon (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Silicon on account of the Obligations three Business Days after
receipt by Silicon of immediately available funds, and, for purposes of the
foregoing, any such funds received after 12:00 Noon on any day shall be deemed
received on the next Business Day. Silicon shall not, however, be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to Silicon in its sole discretion, and Silicon may charge
Borrower's loan account for the amount of any item of payment which is returned
to Silicon unpaid.

     9.2 Application of Payments. All payments with respect to the Obligations
may be applied, and in Silicon's sole discretion reversed and re-applied, to the
Obligations, in such order and manner as Silicon shall determine in its sole
discretion.

     9.3 Charges to Accounts. Silicon may, in its discretion, require that
Borrower pay monetary Obligations in cash to Silicon, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate
applicable to the Loans. Silicon may also, in its discretion, charge any
monetary Obligations to Borrower's Deposit Accounts maintained with Silicon.

     9.4 Monthly Accountings. Silicon shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Silicon), unless Borrower
notifies Silicon in writing to the contrary within thirty days after each
account is rendered, describing the nature of any alleged errors or admissions.

     9.5 Notices. All notices to be given under this Agreement shall be in
writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, or certified mail return receipt
requested, addressed to Silicon or Borrower at the addresses shown in the
heading to this Agreement, or at any other address designated in writing by one
party to the other party. Notices to Silicon shall be directed to the Commercial
Finance Division, to the attention of the Division Manager or the Division
Credit Manager. All notices shall be deemed to have been given upon delivery in
the case of notices personally delivered, or at the expiration of one Business
Day following delivery to the private delivery service, or two Business Days
following the deposit thereof in the United States mail, with postage prepaid.

     9.6 Severability. Should any provision of this Agreement be held by any
court of competent jurisdiction to be void or unenforceable, such defect shall
not affect the remainder of this Agreement, which shall continue in full force
and effect.

     9.7 Integration. This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Borrower and Silicon and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement. There are
                                                                      ---------
no oral understandings, representations or agreements between the parties which
-------------------------------------------------------------------------------
are not set forth in this Agreement or in other written agreements signed by the
--------------------------------------------------------------------------------
parties in connection herewith.
------------------------------

     9.8 Waivers. The failure of Silicon at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Silicon shall not waive
or diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been
waived by any act or knowledge of Silicon or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Silicon on which Borrower is or may in any way be liable, and notice of any
action taken by Silicon, unless expressly required by this Agreement.

     9.9 No Liability for Ordinary Negligence. Neither Silicon, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon shall be liable for any claims, demands, losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower
or any other

           Silicon Valley Bank                  Loan and Security Agreement
--------------------------------------------------------------------------------

party through the ordinary negligence of Silicon, or any of its directors,
officers, employees, agents, attorneys or any other Person affiliated with or
representing Silicon, but nothing herein shall relieve Silicon from liability
for its own gross negligence or willful misconduct.

     9.10 Amendment. The terms and provisions of this Agreement may not be
waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Silicon.

     9.11 Time of Essence. Time is of the essence in the performance by Borrower
of each and every obligation under this Agreement.

     9.12 Attorneys Fees and Costs. Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or prosecute
any probate claim, bankruptcy claim, third-party claim, or other claim; examine,
audit, copy, and inspect any of the Collateral or any of Borrower's books and
records; protect, obtain possession of, lease, dispose of, or otherwise enforce
Silicon's security interest in, the Collateral; and otherwise represent Silicon
in any litigation relating to Borrower. In satisfying Borrower's obligation
                                        -----------------------------------
hereunder to reimburse Silicon for attorneys fees, Borrower may, for
--------------------------------------------------------------------
convenience, issue checks directly to Silicon's attorneys, Levy, Small & Lallas,
--------------------------------------------------------------------------------
but Borrower acknowledges and agrees that Levy, Small & Lallas is representing
------------------------------------------------------------------------------
only Silicon and not Borrower in connection with this Agreement. If either
----------------------------------------------------------------
Silicon or Borrower files any lawsuit against the other predicated on a breach
of this Agreement, the prevailing party in such action shall be entitled to
recover its reasonable costs and attorneys' fees, including (but not limited to)
reasonable attorneys' fees and costs incurred in the enforcement of, execution
upon or defense of any order, decree, award or judgment. All attorneys' fees and
costs to which Silicon may be entitled pursuant to this Paragraph shall
immediately become part of Borrower's Obligations, shall be due on demand, and
shall bear interest at a rate equal to the highest interest rate applicable to
any of the Obligations.

     9.13 Benefit of Agreement. The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Silicon; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Silicon, and any prohibited
assignment shall be void. No consent by Silicon to any assignment shall release
Borrower from its liability for the Obligations.

     9.14 Joint and Several Liability. If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

     9.15 Limitation of Actions. Any claim or cause of action by Borrower
against Silicon, its directors, officers, employees, agents, accountants or
attorneys, based upon, arising from, or relating to this Loan Agreement, or any
other present or future document or agreement, or any other transaction
contemplated hereby or thereby or relating hereto or thereto, or any other
matter, cause or thing whatsoever, occurred, done, omitted or suffered to be
done by Silicon, its directors, officers, employees, agents, accountants or
attorneys, shall be barred unless asserted by Borrower by the commencement of an
action or proceeding in a court of competent jurisdiction by the filing of a
complaint within one year after the first act, occurrence or omission upon which
such claim or cause of action, or any part thereof, is based, and the service of
a summons and complaint on an officer of Silicon, or on any other person
authorized to accept service on behalf of Silicon, within thirty (30) days
thereafter. Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Silicon in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

     9.16 Paragraph Headings; Construction. Paragraph headings are only used in
this Agreement for convenience. Borrower and Silicon acknowledge that the
headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit,
define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between the
parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Silicon or Borrower under any rule
of construction or otherwise.

     9.17 Governing Law; Jurisdiction; Venue. This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and Borrower
shall be governed by the laws of the State of California. As a material part of
the consideration to Silicon to enter into this Agreement, Borrower (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Silicon's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Santa Clara County;
(ii) consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or any
other method permitted by law; and (iii) waives any and all rights Borrower may
have to object to the jurisdiction of any such court, or to transfer or change
the venue of any such action or proceeding.

     9.18 Mutual Waiver of Jury Trial. BORROWER AND SILICON EACH HEREBY WAIVE
THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT
OF, OR IN ANY WAY RELATING TO, THIS

                          Loan and Security Agreement

Borrower: HAHT Commerce, Inc.
Address:  400 Newton Road
          Raleigh, North Carolina  27615

Date:     October __, 2000

This Schedule forms an integral part of the Loan and Security Agreement between
Silicon Valley Bank and the above-borrower of even date.

================================================================================

1.   CREDIT LIMIT
     (Section 1.1):           An amount not to exceed the lesser of: (i)
                              $4,000,000 at any one time outstanding (the
                              "Maximum Credit Limit"); or (ii) 75% of the amount
                              of Borrower's Eligible Receivables (as defined in
                              Section 8 above).

================================================================================

2.   INTEREST.

      Interest Rate (Section 1.2):

                              A rate equal to the "Prime Rate" in effect from
                              time to time, plus 2.00% per annum. Interest shall
                              be calculated on the basis of a 360-day year for
                              the actual number of days elapsed. "Prime Rate"
                              means the rate announced from time to time by
                              Silicon as its "prime rate;" it is a base rate
                              upon which other rates charged by Silicon are
                              based, and it is not necessarily the best rate
                              available at Silicon. The interest rate applicable
                              to the Obligations shall change on each date there
                              is a change in the Prime Rate.

      Minimum Monthly
      Interest (Section 1.2): N/A per month.

3.   FEES (Section 1.4):

      Loan Fee:               $40,000, payable concurrently herewith.

      Collateral Monitoring   $1,000, per month, payable in arrears
      Fee:                    (prorated for any partial month at the
                              beginning and at termination of this

                       the month is less than the amount of the Maximum Credit

                       average daily principal balance of the Loans outstanding
                       during the month, which unused line fee shall be computed

                         application or registration. Borrower will: (i)
                         protect, defend and maintain the validity and
                         enforceability of the copyrights, patents, and
                         trademarks; (ii) promptly advise Bank in writing of
                         material infringements of the copyrights, patents, or

                    (d)  Warrants. Borrower shall provide Silicon with five-year
                         warrants to purchase the Designated Number (as defined
                         herein) of shares of preferred stock of the Borrower,
                         at a price per share equal to the Designated Price (as
                         defined herein), on terms acceptable to Silicon, all as
                         set forth in the Warrant to Purchase Stock (the
                         "Warrant") and related documents (including but not
                         limited to any Anti-Dilution Agreement or any
                         Registration Rights Agreement as may be required by
                         Silicon) being executed concurrently with this
                         Agreement. Said warrants shall be deemed fully earned
                         on the date hereof, shall be in addition to all
                         interest and other fees, and shall be non-refundable.
                         As used herein, the term "Designated Number" means the
                         quotient obtained by dividing $200,000 by the
                         Designated Price. As used herein, the term "Designated
                         Price" means the average of the Next Round Price (as
                         defined herein) and the Last Round Price (as defined
                         herein); provided, however, that that if the Next Round
                         does not occur by August 31, 2001, or if an Acquisition
                         (as defined in the Warrant) occurs on or before August
                         31, 2001, the Designated Price shall be the Last Round
                         Price. The "Last Round Price" means $0.929 per share,
                         which Borrower represents and warrants is the price per
                         share at which shares of Borrower's Series E preferred
                         stock were previously issued (and if they were issued
                         at more than one price, the lowest of such prices). The
                         "Next Round Price" means the price per share at which
                         the next bona fide issuance of preferred stock of
                         Borrower is made in an offering in which not less than
                         $5,000,000 is raised by Borrower (the "Next Round").

                         options or warrants to acquire stock of any Subsidiary.

date first set forth above. The above information is subject to all of the terms
and conditions of this Agreement. The parties agree as follows:

     1. Loans and Payments.
        ------------------

        (a) Loans. Sand Hill will, on the Borrower's request, make one or more
            -----
loans (each, a "Loan" and collectively, the "Loans") to Borrower from time to
time, in an aggregate amount not to exceed the principal sum of $4,000,000 at
any time outstanding before the earlier of (i) the date Borrower accepts a
signed term sheet in form and substance reasonably satisfactory to Sand Hill for
the sale of Borrower's equity securities in an amount not less than $10,000,000
or (ii) the date Borrower files a Form S-1 in connection with an underwritten
public offering of its equity securities, in each case with proceeds to Borrower
of at least $10,000,000, and an aggregate amount not to exceed the principal sum
of $7,000,000 thereafter, subject to all of the terms and conditions of this
Agreement. Loans shall be made in minimum disbursements of $100,000 each.
Requests for Loans shall be submitted by Borrower to Sand Hill in writing three
(3) business days prior to the date the Loan is to be made, which shall be a
business day. Loans may be prepaid at any time without penalty.

        (b) Conditions Precedent. Notwithstanding any provisions herein to the
            --------------------
contrary, Loans will not be made hereunder until (i) all filings have been
completed that are necessary or appropriate to perfect the
<PAGE>

security interest of Sand Hill in the personal property of Borrower, (ii) all
documents requested by Sand Hill in connection with this Agreement have been
delivered to Sand Hill, (iii) Sand Hill has confirmed to its satisfaction that
there has been no material adverse change in the financial condition, operation
or prospects of Borrower, and (iv) all other matters relating to the requested
Loans have been completed to Sand Hill's satisfaction.

        (c) Interest. Borrower shall pay interest on all outstanding Loans and
            --------
other monetary Obligations at a floating rate equal to the Prime Rate, as
published in the Western Edition of The Wall Street Journal from time to time,
plus 3% percent per annum. Interest shall be adjusted each day there is a change
in the Prime Rate. Interest shall be calculated on the basis of a 360-day year
for the actual number of days elapsed, and shall be payable in arrears on the
first day of each month.

        (d) Fees. Borrower shall pay Sand Hill a Loan Fee of $40,000 (the
            ----
receipt of which by Sand Hill is hereby acknowledged), and an additional $30,000
as a condition to requesting any Loans in an aggregate amount in excess of
$4,000,000, which shall be due and fully earned on the date of this Agreement,
and non-refundable.

        (e) Warrants. Borrower is concurrently issuing to Sand Hill a Warrant to
            --------
Purchase Stock on the terms and conditions set forth therein (the "Warrant"). At
Sand Hill's request, Borrower will divide the Warrant and issue separate
Warrants on the same terms to Sand Hill's participants for the number of shares
Sand Hill specifies, and a Warrant for the balance of the shares to Sand Hill.

        (f) Investment. Sand Hill shall have a right to purchase shares of
            ----------
Borrower's equity securities (the "Shares") of the type, for the price, and on
substantially the same terms as those offered to other purchasers (including in
any case piggyback and S-3 registration rights) in its next private sale or
issuance of equity securities (the "Next Offering"), provided that, if more than
one price per share is being paid by the purchasers, the price to Sand Hill
shall be the lowest of such prices. The number of shares to be purchased by Sand
Hill shall be determined by Sand Hill in its discretion, provided that the total
purchase price may not exceed $1,000,000. Borrower shall give Sand Hill written
notice of the date of the Next Offering at least 10 days prior to the date the
Next Offering is to be consummated, and Sand Hill may exercise its right to
purchase such preferred stock by written notice to Borrower within 30 days after
the date the Next Offering is consummated. Within five business days after the
date that the Next Offering is consummated, Borrower shall give Sand Hill
written notice thereof and such information concerning the same as Sand Hill
shall reasonably request. Promptly following the exercise of such right by Sand
Hill, Borrower shall issue the Shares to Sand Hill, and Sand Hill shall
concurrently pay the purchase price thereof. The rights under this Section may
be exercised by Sand Hill or its participants and designees, and shall survive
termination of this Agreement.

        (g) Maturity Date; Extension. The entire outstanding principal balance
            ------------------------
of the Loans and all accrued and unpaid interest thereon and all other monetary
Obligations shall be due and payable on the Original Maturity Date, and
thereafter no further Loans will be made; provided that, if no Event of Default
or event which with notice or lapse of time would constitute an Event of Default
has occurred and is continuing, Borrower may extend the Original Maturity Date
by 30 days by giving Sand Hill written notice that Borrower wishes to extend the
Original Maturity Date at least 10 days before the Original Maturity Date,
whereupon the number of shares that may be purchased under the Warrant shall
automatically be increased by a number equal to the quotient derived by dividing
$100,000 by the Warrant Price, as defined in the Warrant. Notwithstanding the
foregoing, whether or not Borrower has requested that Sand Hill extend the
Original Maturity Date, if Borrower has not repaid all Obligations in full on or
before the Original Maturity Date, the number of shares of Borrower's stock that
may be purchased under the Warrant shall automatically be increased by a number
equal to the quotient derived by dividing $100,000 by the Warrant Price. In
addition, if any amount is outstanding after the Extended Maturity Date, the
number of shares of Borrower's stock that may be purchased under the Warrant
will further increase by a number equal to the quotient derived by dividing
$4,000 by the Warrant Price for each day that any such amount remains
outstanding. The provisions in this paragraph shall not be construed as Sand
Hill's consent to Borrower's failure to pay any amounts in strict accordance
with this Agreement, and Sand Hill's acceptance of any such late payments shall
not restrict Sand Hill's exercise of any remedies arising out of any such
failure.

        (h) Payments. Sand Hill shall maintain an account on its books in the
            --------
name of Borrower (the "Loan Account"). All Loans made by Sand Hill to Borrower
or for Borrower's account will be charged to the Loan

                                       2
<PAGE>

Account. All amounts received by Sand Hill from Borrower or for Borrower's
account will be credited to the Loan Account. Accrued interest and other
monetary Obligations may also, in Sand Hill's discretion, be charged to the Loan
Account, and will bear interest from the date so charged to the date paid. For
all purposes of this Agreement any payments received by Sand Hill will only be
deemed received when received in immediately available funds, and any
immediately available funds received later than 2:00 p.m. (California time) on
any business day shall be deemed to have been received on the following business
day and any applicable interest or fee shall continue to accrue during such
period.

        (i) Late Payment. If any payment of interest or any other amount owing
            ------------
to Sand Hill is not made within ten (10) days after the due date, Borrower shall
pay Sand Hill a late payment fee equal to the lesser of 5% of the amount of such
late payment or the maximum amount permitted by law. After the occurrence and
during the continuance of an Event of Default, the Obligations shall bear
interest at a rate equal to the greater of 18% per annum or 5% above the rate
otherwise applicable under this Agreement. The provisions in this paragraph
shall not be construed as Sand Hill's consent to Borrower's failure to pay any
amounts in strict accordance with this Agreement, and Sand Hill's acceptance of
any such late payments shall not restrict Sand Hill's exercise of any remedies
arising out of any such failure.

     2. Grant of Security Interest. Borrower grants Sand Hill a security
        --------------------------
interest in all of the assets and property described in Exhibit A hereto (the
                                                        ---------
"Collateral") to secure the following (the "Obligations"): the obligation to
repay all Loans, and all other debts, liabilities, obligations, guaranties,
covenants and duties now or hereafter owing by Borrower to Sand Hill, of any
kind or nature, whether or not evidenced by any note, guaranty or other
instrument, whether arising under or in connection with this Agreement, or any
other present or future instrument or agreement, whether arising by reason of an
extension of credit, loan, guaranty, indemnification or in any other manner.
Borrower shall take all such actions as Sand Hill requests from time to time to
perfect or continue the perfection of the security interest granted hereunder.

     3. Representations and Warranties. Borrower represents to Sand Hill as
        ------------------------------
follows (which shall be deemed continuing throughout the term of this
Agreement):

        (a) Authorization. Borrower is and will continue to be, duly organized,
            -------------
validly existing and in good standing under the laws of the jurisdiction of its
incorporation, and Borrower is and will continue to be qualified and licensed to
do business in all jurisdictions in which any failure to do so would have a
Material Adverse Effect; the execution, delivery and performance by Borrower of
this Agreement, and all other documents contemplated hereby have been duly and
validly authorized by all necessary corporate action, and do not violate
Borrower's articles or certificate of incorporation, or by-laws, or any law or
any material agreement or instrument which is binding upon Borrower or its
property. Borrower has no wholly-owned or partially owned subsidiaries and is
not a partner or joint venturer in any partnership or joint venture, except as
set forth on Exhibit B. Borrower's correct name is set forth in on the cover
page to this Agreement, and Borrower will give Sand Hill written notice within
15 days after changing Borrower's name.

        (b) Places of Business; Locations of Collateral. The address set forth
            -------------------------------------------
in this Agreement under Borrower's signature is Borrower's chief executive
office. Borrower has places of business and Collateral is located only at the
locations set forth on Exhibit B hereto. Borrower will give Sand Hill written
notice within 15 days after changing Borrower's chief executive office, or
moving any of the Collateral to another state (other than a state in which Sand
Hill's security interest is perfected), or opening a place of business in
another state (other than a state in which Sand Hill's security interest is
perfected).

        (c) Title to Collateral; Permitted Liens. Borrower is now, and will at
            ------------------------------------
all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower. The Collateral now is and will
remain free and clear of any and all liens, security interests, encumbrances and
adverse claims, except for Permitted Liens, and Borrower will at all times
defend Sand Hill and the Collateral against all claims of others. As used
herein, "Permitted Liens" shall mean the following: (i) purchase money security
interests in specific items of Equipment; (ii) leases of specific items of
Equipment; (iii) liens for taxes, fees, assessments or other governmental
charges or levies, either not delinquent or being contested in good faith by
appropriate proceedings, provided the same have no priority over any of Sand
Hill's security interests; (iv) liens of materialmen, mechanics, warehousemen,
carriers, or other similar liens arising in the ordinary course of business and
securing obligations

                                       3

which are not delinquent more than 30 days or are being contested in good faith
by appropriate proceedings, (v) any judgment, attachment or similar lien, which
has been discharged or execution on which has been stayed and which has been
bonded against pending appeal within 30 days of the entry thereof; (vi) Liens
which constitute banker's liens, rights of set-off or similar rights and
remedies as to deposit accounts or other funds maintained with any bank or other
financial institution; and (vii) the Lien of Silicon Valley Bank, which shall
secure an outstanding obligation not to exceed $4,000,000.

        (d) Financial Condition, Statements and Reports. All financial
            -------------------------------------------
statements now or in the future delivered to Sand Hill have been, and will be,
prepared in conformity with generally accepted accounting principles (except for
the absence of footnotes and subject to normal year-end adjustments with respect
to unaudited financial statements, and except in the case of projections or
forecasts for the understanding that although Borrower has prepared the same in
good faith utilizing assumptions it believes to be reasonable, Sand Hill
recognizes that forecasts and assumptions by their nature involve approximations
and uncertainties). All financial statements now or in the future delivered to
Sand Hill will fairly reflect the financial condition of Borrower, at the times
and for the periods therein stated. Between the last date covered by any such
statement provided to Sand Hill and the date hereof, there has been no Material
Adverse Effect.

        (e) Tax Returns and Payments. Borrower has timely filed, and will timely
            ------------------------
file, all tax returns and reports required by applicable law, and Borrower has
timely paid, and will timely pay, all applicable taxes, assessments, deposits
and contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Sand Hill in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral.

        (f) Compliance with Law. Borrower has complied, and will comply, in all
            -------------------
material respects, with all provisions of all applicable laws and regulations,
including, but not limited to, those relating to Borrower's ownership of real or
personal property, the conduct and licensing of Borrower's business, and all
environmental matters, except where the failure to do so would not have a
Material Adverse Effect.

        (g) Litigation. Except as disclosed on Exhibit B hereto, there is no
            ----------
claim or litigation pending or (to best of Borrower's knowledge) threatened
against Borrower which, either separately or in the aggregate, is reasonably
likely to have a Material Adverse Effect. Borrower will promptly inform Sand
Hill in writing of any claim or litigation in the future which, either
separately or in the aggregate, is reasonably likely to have a Material Adverse
Effect.

        (h) Information. All information provided to Sand Hill by or on behalf
            -----------
of Borrower on or prior to the date of this Agreement is true and correct in all
material respects, and no representation or other statement made by Borrower to
Sand Hill contains any untrue statement of a material fact or omits to state a
material fact necessary to make any statements made to Sand Hill not misleading
at the time made.

     4. Covenants.
        ---------

        (a) Reports. Borrower will provide to Sand Hill in form and substance
            -------
acceptable to Sand Hill (i) monthly unaudited financial statements within thirty
(30) days after the last day of each month (other than the month in which
Borrower's fiscal year ends); (ii) audited fiscal year end financial statements
with an unqualified opinion within one hundred twenty (120) days after the last
day of each fiscal year; and (iii) upon request, such other information relating
to Borrower's operations and condition, including information on equity and
funding status, as Sand Hill may reasonably request from time to time. Sand Hill
shall have the right to review and copy Borrower's books and records and audit
and inspect the Collateral, from time to time, upon reasonable notice to
Borrower. Borrower will reimburse Sand Hill for the reasonable costs it may
incur from time to time in such inspections and review.

        (b) Insurance. Borrower will maintain insurance on the Collateral and
            ---------
Borrower's business, in amounts and of a type that are customary to businesses
similar to Borrower's, and Sand Hill will be named in a lender's loss payable
endorsement in favor of Sand Hill, in form reasonably acceptable to Sand Hill.

                                       4
<PAGE>

        (c) Negative Covenants. Borrower shall not, without Sand Hill's prior
            ------------------
written consent, do any of the following: (i) merge or consolidate with another
corporation or entity, except in a transaction in which the shareholders of the
Borrower hold at least 50% of the common stock and all other capital stock of
the surviving corporation immediately after such merger or consolidation, and
the Borrower is the surviving corporation; (ii) acquire any assets, except in
the ordinary course of business or in a transaction involving the payment of an
aggregate amount of $250,000 or less; (iii) enter into a transaction outside the
ordinary course of business; (iv) sell, lease, or transfer any Collateral except
for sales of Inventory and Equipment in the ordinary course of business; (v)
transfer, sell or license any intellectual property, except for non-exclusive
licenses thereof; (vi) pay or declare any dividends on Borrower's stock (except
for dividends payable solely in stock of Borrower); (vii) redeem, purchase or
otherwise acquire, any of Borrower's stock, except that Borrower may repurchase
stock in a total amount not to exceed $100,000 in any fiscal year pursuant to a
stock repurchase agreement applicable to employees, officers, directors and/or
consultants as long as no Default or Event of Default exists prior to or after
giving effect to such repurchase; (viii) make any investments in, or loans or
advances to, any person other than in the ordinary course of business as
currently conducted; or (ix) directly or indirectly enter into any material
transaction with any affiliate of Borrower except for transactions that are in
the ordinary course of Borrower's business, and on fair and reasonable terms
that are no less favorable to Borrower than would be obtained in an arm's length
transaction with a non-affiliated person; or (x) make any payment on any
indebtedness which is subordinate to the Obligations, other than in accordance
with the subordination agreement in favor of Sand Hill relating thereto; or (xi)
agree to do any of the foregoing.

        (d) Intellectual Property. Borrower is concurrently executing and
            ---------------------
delivering to Sand Hill an Intellectual Property Security Agreement. Borrower
shall use its best efforts to register all of its software and other
copyrightable intellectual property with the United States Copyright Office
within 15 days after the date of this Agreement and shall provide evidence of
the same to Sand Hill as soon as practicable, provided that Sand Hill shall have
                                              --------
no obligations to extend Loans to Borrower hereunder until such time Sand Hill
has received such evidence and other conditions set forth hereunder have been
satisfied. Borrower will promptly register such additional intellectual property
rights developed or acquired by Borrower from time to time hereafter, and
Borrower will execute such documents and take such other actions as Sand Hill
may reasonably request to perfect the security interest granted in all
Intellectual Property. Borrower represents and warrants to Sand Hill that
Borrower is the sole owner of the Intellectual Property, except for
non-exclusive licenses granted by Borrower to its customers in the ordinary
course of business. Each of the patents included in the Intellectual Property is
valid and enforceable, and no part of the Intellectual Property has been judged
invalid or unenforceable, in whole or in part, and no claim has been made that
any part of the Intellectual Property violates the rights of any third party.

        (e) Directors Information. Borrower shall give Sand Hill copies of all
            ---------------------
notices, minutes, consents and other materials the Borrower provides to its
directors in connection with meetings of the directors; provided that the
Borrower reserves the right to withhold any information if access to such
information could adversely affect the attorney-client privilege between the
Borrower and its counsel. Any information provided to Sand Hill shall be subject
to the confidentiality agreement in Section 9 below.

     5. Events of Default. Any one or more of the following shall constitute an
        -----------------
Event of Default under this Agreement:

        (a) Borrower shall fail to pay any principal of or interest on any Loans
or any other monetary Obligations within five days after the date due;

        (b) Borrower shall fail to comply with any other provision of this
Agreement, which failure is not cured within ten days of Sand Hill providing
notice thereof;

        (c) Any warranty, representation, statement, report or certificate made
or delivered to Sand Hill by Borrower or on Borrower's behalf shall be untrue or
misleading in a material respect as of the date given or made; or

        (d) There shall be a change in the record or beneficial ownership of an
aggregate of more than 30% of the outstanding shares of stock of Borrower, in
one or more transactions, compared to the ownership of

                                       5
<PAGE>

outstanding shares of stock of Borrower in effect on the date hereof, except for
(i) changes with the prior written consent of Sand Hill or (ii) changes as a
result of an initial public offering of Borrower's stock; or

        (e) Dissolution, termination of existence, or insolvency of Borrower; or
Borrower fails to meet its debts as they mature; or appointment of a receiver,
trustee or custodian, for all or any material part of the property of,
assignment for the benefit of creditors by, or the commencement of any
proceeding by or against Borrower under any reorganization, bankruptcy,
insolvency, arrangement, readjustment of debt, dissolution or liquidation law or
statute of any jurisdiction, now or in the future in effect (except that, in the
case of a proceeding commenced against Borrower, Borrower shall have 60 days
after the date such proceeding was commenced to have it dismissed); or

        (f) The occurrence of a "Material Adverse Effect", which shall mean (i)
a material adverse change in the business, prospects, operations, results of
operations, assets, liabilities or financial or other condition of Borrower,
(ii) the impairment of Borrower's ability to perform its Obligations or of Sand
Hill's ability to enforce the Obligations or realize upon the Collateral, or
(iii) a material adverse change in the value of the Collateral.

        (g) Sand Hill may cease making any Loans hereunder during any of the
above cure periods, and thereafter if an Event of Default has occurred and is
continuing.

     6. Remedies.
        --------

        (a) Remedies. Upon the occurrence and during the continuance of any
            --------
Event of Default, Sand Hill, at its option, may do any one or more of the
following, without notice except for such notices as are required by law: (a)
Accelerate and declare the Obligations to be immediately due, payable, and
performable, notwithstanding any deferred or installment payments allowed by any
instrument evidencing or relating to any Obligation; (b) Take possession of any
or all of the Collateral wherever it may be found, and for that purpose Borrower
hereby authorizes Sand Hill to enter Borrower's premises without interference to
search for, take possession of, keep, store, or remove any of the Collateral,
and remain on the premises or cause a custodian to remain on the premises in
exclusive control thereof, without charge by Borrower for so long as Sand Hill
reasonably deems it necessary in order to complete the enforcement of its rights
under this Agreement or any other agreement; provided, however, that should Sand
Hill seek to take possession of any of the Collateral by Court process, Borrower
hereby waives: (i) any bond and any surety or security relating thereto; (ii)
any demand for possession prior to the commencement of any suit or action to
recover possession thereof; and (iii) any requirement that Sand Hill retain
possession of, and not dispose of, any such Collateral until after trial or
final judgment; (c) Require Borrower to assemble any or all of the Collateral
and make it available to Sand Hill at places designated by Sand Hill which are
reasonably convenient to Sand Hill and Borrower, and to remove the Collateral to
such locations as Sand Hill may reasonably deem advisable; (d) Complete the
processing, manufacturing or repair of any Collateral prior to a disposition
thereof and, for such purpose and for the purpose of removal, Sand Hill shall
have the right to use Borrower's premises, equipment and all other property
without charge by Borrower; (e) Collect, receive, dispose of and realize upon
any investment property, including withdrawal of any and all funds from any
securities accounts; (f) Sell, lease or otherwise dispose of any of the
Collateral, at one or more public or private sales, in lots or in bulk, for
cash, exchange or other property, or on credit, and to adjourn any such sale
from time to time without notice other than oral announcement at the time
scheduled for sale. Sand Hill shall have the right to conduct such disposition
on Borrower's premises without charge, for such time or times as Sand Hill deems
reasonable, or on Sand Hill's premises, or elsewhere and the Collateral need not
be located at the place of disposition; (g) Demand payment of, and collect any
accounts, general intangibles or other Collateral and, in connection therewith,
Borrower irrevocably authorizes Sand Hill to endorse or sign Borrower's name on
all collections, receipts, instruments and other documents, and, in Sand Hill's
good faith business judgment, to grant extensions of time to pay, compromise
claims and settle accounts, general intangibles and the like for less than face
value; and (h) Demand and receive possession of any of Borrower's federal and
state income tax returns and the books and records utilized in the preparation
thereof or referring thereto. Borrower recognizes that Sand Hill may be unable
to make a public sale of any or all of the investment property, by reasons of
prohibitions contained in applicable securities laws or otherwise, and expressly
agrees that a private sale to a restricted group of purchasers for investment
and not with a view to any distribution thereof shall be considered a
commercially reasonable sale. All reasonable attorneys' fees, expenses, costs,
liabilities and obligations incurred by Sand Hill with respect to the foregoing
shall be added to and become part of the Obligations, and shall be due on
demand.

                                       6
<PAGE>

        (b) Application of Proceeds. All proceeds realized as the result of any
            -----------------------
sale or other disposition of the Collateral shall be applied by Sand Hill first
to the reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by Sand Hill in the exercise of its rights under this Agreement, second
to the interest due upon any of the Obligations, and third to the principal of
the Obligations, in such order as Sand Hill shall determine in its sole
discretion. Any surplus shall be paid to Borrower or other persons legally
entitled thereto; Borrower shall remain liable to Sand Hill for any deficiency.
If Sand Hill, in its good faith business judgment, directly or indirectly enters
into a deferred payment or other credit transaction with any purchaser at any
sale of Collateral, Sand Hill shall have the option, exercisable at any time, in
its sole discretion, of either reducing the Obligations by the principal amount
of the purchase price or deferring the reduction of the Obligations until the
actual receipt by Sand Hill of the cash therefor.

        (c) Remedies Cumulative. In addition to the rights and remedies set
            -------------------
forth in this Agreement, Sand Hill shall have all the other rights and remedies
accorded a secured party under the California Uniform Commercial Code and under
all other applicable laws, and under any other instrument or agreement now or in
the future entered into between Sand Hill and Borrower, and all of such rights
and remedies are cumulative and none is exclusive. Exercise or partial exercise
by Sand Hill of one or more of its rights or remedies shall not be deemed an
election, nor bar Sand Hill from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Sand Hill to exercise any
rights or remedies shall not operate as a waiver thereof, but all rights and
remedies shall continue in full force and effect until all of the Obligations
have been fully paid and performed.

        (d) Power of Attorney. After the occurrence and during the continuance
            -----------------
of an Event of Default, Borrower irrevocably appoints Sand Hill (and any of Sand
Hill's designated employees or agents) as Borrower's true and lawful attorney in
fact to: endorse Borrower's name on any checks or other forms of payment; make,
settle and adjust all claims under and decisions with respect to Borrower's
policies of insurance; settle and adjust disputes and claims respecting
accounts, general intangibles and other Collateral; execute and deliver all
notices, instruments and agreements in connection with the perfection of the
security interest granted in this Agreement; sell, lease or otherwise dispose of
all or any part of the Collateral; and take any other action or sign any other
documents required to be taken or signed by Borrower, or reasonably necessary to
enforce Sand Hill's rights or remedies or otherwise carry out the purposes of
this Agreement. The appointment of Sand Hill as Borrower's attorney in fact, and
each of Sand Hill's rights and powers, being coupled with an interest, are
irrevocable until all Obligations owing to Sand Hill have been paid and
performed in full.

        (e) Waivers. The failure of Sand Hill at any time or times to require
            -------
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Sand Hill shall not waive
or diminish any right of Sand Hill later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement shall be deemed to have been
waived except by a specific written waiver signed by an authorized officer of
Sand Hill and delivered to Borrower. Borrower waives demand, protest, notice of
protest and notice of default or dishonor, notice of payment and nonpayment,
release, compromise, settlement, extension or renewal of any commercial paper,
instrument, account, general intangible, document or guaranty at any time held
by Sand Hill on which Borrower is or may in any way be liable, and notice of any
action taken by Sand Hill, unless expressly required by this Agreement.

        (f) Costs; Indemnity. Borrower shall reimburse Sand Hill and its
            ----------------
participants for all of the following ("Costs"): all reasonable attorneys' fees
and all filing, recording, search, title insurance, appraisal, audit, and other
reasonable costs incurred by Sand Hill and its participants, pursuant to, in
connection with, or relating to this Agreement or its enforcement (whether or
not any lawsuit is filed), including, but not limited to, any reasonable
attorneys' fees and costs Sand Hill incurs relating to preparation and
negotiation of this Agreement and the documents relating to this Agreement. Sand
Hill shall provide an itemized statement of Costs to Borrower, if so requested
by Borrower. If either Sand Hill or Borrower files any lawsuit against the other
predicated on a breach of this Agreement, the prevailing party in such action
shall be entitled to recover its reasonable costs, including (but not limited
to) reasonable attorneys' fees incurred in connection therewith. Borrower shall
indemnify Sand Hill for any losses, claims, actions, causes of action,
penalties, and reasonable costs and expenses (including reasonable attorneys'
fees), which Sand Hill may sustain or incur based upon or arising out of this
Agreement, any of the Obligations, any other relationship or agreement between
Sand Hill and Borrower, or any other matter relating to Borrower or the
Obligations, except any such amounts sustained or incurred as the result of the
gross negligence or

                                       7
<PAGE>

willful misconduct of Sand Hill or any of its directors, officers, employees,
agents, attorneys, or any other person affiliated with or representing Sand
Hill. The indemnity agreement set forth in this Section shall survive any
termination of this Agreement and shall continue in full force and effect.

     7. Confidentiality. In handling any confidential non-public information
        ---------------
provided to Sand Hill by Borrower, Sand Hill shall exercise the same degree of
care that it exercises with respect to its own proprietary information of the
same types to maintain the confidentiality of the same, except that disclosure
of such information may be made (i) to subsidiaries or affiliates of Sand Hill
in connection with their present or prospective business relations with
Borrower, (ii) to prospective transferees or purchasers of any interest in the
Obligations, provided that they have entered into a comparable confidentiality
agreement with respect thereto, (iii) as required by law, regulations, rule or
order, subpoena, judicial order or similar order, (iv) as may be required in
connection with the examination, audit or similar investigation of Sand Hill,
and (v) as Sand Hill may deem appropriate in connection with the exercise of any
remedies hereunder. Confidential information hereunder shall not include
information that either: (a) is in the public domain, or becomes part of the
public domain, after disclosure to Sand Hill through no fault of Sand Hill; or
(b) is disclosed to Sand Hill by a third party, provided Sand Hill does not have
actual knowledge that such third party is prohibited from disclosing such
information.

     8. Notices. All notices under this Agreement shall be in writing and shall
        -------
be deemed to have been given (a) upon receipt, when delivered by hand or by
electronic facsimile transmission, or (b) upon actual delivery by overnight
courier, or (c) three days after mailing by regular first-class mail or
certified mail return receipt requested, addressed to each party at the
addresses indicated below their signatures below.

     9. Governing Law; Jurisdiction; Venue. This Agreement and all acts and
        ----------------------------------
transactions hereunder and all rights and obligations of Sand Hill and Borrower
shall be governed by the internal laws (and not the conflict of laws rules) of
the State of California. As a material part of the consideration to Sand Hill to
enter into this Agreement, Borrower (i) agrees that all actions and proceedings
relating directly or indirectly to this Agreement shall, at Sand Hill's option,
be litigated in courts located within California, and that the exclusive venue
therefor shall be Santa Clara County; (ii) consents to the jurisdiction and
venue of any such court and consents to service of process in any such action or
proceeding by personal delivery or any other method permitted by law; and (iii)
waives any and all rights Borrower may have to object to the jurisdiction of any
such court, or to transfer or change the venue of any such action or proceeding.

     10. MUTUAL WAIVER OF JURY TRIAL. BORROWER AND SAND HILL EACH HEREBY WAIVE
         ---------------------------
THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT
OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE
INSTRUMENT OR AGREEMENT BETWEEN SAND HILL AND BORROWER, OR ANY CONDUCT, ACTS OR
OMISSIONS OF SAND HILL OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SAND HILL OR
BORROWER, IN ALL OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR
OTHERWISE.

     11. General. Should any provision of this Agreement be held by any court of
         -------
competent jurisdiction to be void or unenforceable, such defect shall not affect
the remainder of this Agreement, which shall continue in full force and effect.
This Agreement and such other written agreements, documents and instruments as
may be executed in connection herewith are the final, entire and complete
agreement between Borrower and Sand Hill and supersede all prior and
contemporaneous negotiations and oral representations and agreements, all of
which are merged and integrated in this Agreement. There are no oral
understandings, representations or agreements between the parties which are not
set forth in this Agreement or in other written agreements signed by the parties
in connection herewith. The terms and provisions of this Agreement may not be
waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Sand Hill. Sand Hill may assign all or any part of its
interest in this Agreement and the Obligations to any person or entity, or grant
a participation in, or security interest in, any interest in this Agreement,
without notice to, or consent of, Borrower. Borrower may not assign any rights
under or interest in this Agreement without Sand Hill's prior written consent.
This Agreement may be executed in two or more counterparts, each of which shall
be deemed an original, but all of which shall constitute one agreement. If
Borrower consists of more than one Person, their liability shall be joint and
several, and the compromise of any claim with, or the release of, any Borrower
shall not constitute a compromise with, or a release of, any other Borrower.
