of the foregoing, and all books and records related to any of the foregoing.

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

  In order to induce Greyrock to enter into this Agreement and to make Loans,
Borrower represents and warrants to Greyrock 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 (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), (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

                                      -1-

--------------------------------------------------------------------------------

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 Greyrock 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 Greyrock 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.  Greyrock 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 Greyrock and the Collateral against all claims
of others.  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 Greyrock, use
its best efforts to cause such third party to execute and deliver to Greyrock,
in form acceptable to Greyrock, such waivers and subordinations as Greyrock
shall specify, so as to ensure that Greyrock'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, ordinary wear and tear excepted, and Borrower will not use
the Collateral for any unlawful purpose.  Borrower will immediately advise
Greyrock in writing of any material loss or damage to the Collateral.

  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 Greyrock have been, and will be, prepared in
conformity with generally accepted accounting principles * and now and in the
future 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 Greyrock 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.

  *(except for the absence of footnotes and subject to normal year-end
adjustments with respect to unaudited financial statements)

  3.8  Tax Returns and Payments; Pension Contributions.  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 Greyrock 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 Guarantee Corporation or any other governmental
agency.  Borrower shall, at all times, maintain a separate payroll account which
shall be used exclusively for payment of payroll and payroll taxes and other
items related directly to payroll.

  3.9  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.

  *Unless noncompliance would not materially adversely affect (i) Borrower's
financial condition as reflected in its financial

                                      -2-

--------------------------------------------------------------------------------

statements previously delivered to Greyrock, (ii) Borrower's operations, or
(iii) Borrower's business,

  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 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 Greyrock in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower *   any single claim of $50,000
or more, or involving $100,000 or more in the aggregate.

  * which can reasonably be expected to result in liability with respect to

  3.11  Use of Proceeds.  All proceeds of all Loans shall be used solely for
lawful business purposes.

  3.12  Year 2000 Compliance.  The Borrower has (i) initiated a review and
assessment of all areas within its and each of its subsidiaries' business and
operations (including those affected by suppliers and vendors) that could be
adversely affected by the "Year 2000 Problem" (that is, the risk that computer
applications used by the Borrower or any of its subsidiaries (or its suppliers
and vendors) may be unable to recognize and perform properly date-sensitive
functions involving certain dates prior to and any date after December 31,
1999), (ii) developed a plan and timeline for addressing the Year 2000 Problem
on a timely basis, and (iii) to date, implemented that plan in accordance with
that timetable.  The Borrower reasonably believes that all computer applications
(including those of its suppliers and vendors) that are material to its or any
of its subsidiaries' business and operations will on a timely basis be able to
perform properly date-sensitive functions for all dates before and after January
1, 2000 (that is, be "Year 2000 compliant"), except to the extent that a failure
to do so could not reasonably be expected to have material adverse effect. The
Borrower will promptly notify Greyrock in the event the Borrower discovers or
determines that any computer application (including those of its suppliers and
vendors) that is material to its or any of its subsidiaries' business and
operations will not be Year 2000 compliant on a timely basis, except to the
extent that such failure could not reasonably be expected to have a material
adverse effect.

4.  RECEIVABLES.

  4.1  Representations Relating to Receivables.  Borrower represents and
warrants to Greyrock as follows:  Each Receivable with respect to which Loans
are requested by Borrower shall, on the date each Loan is requested and made,
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.

  4.2  Representations Relating to Documents and Legal Compliance.  Borrower
represents and warrants to Greyrock 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 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 Greyrock transaction reports and loan requests, schedules and assignments of
all Receivables, and schedules of collections, all on Greyrock's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Greyrock's security interest and other rights in all of
Borrower's Receivables, nor shall Greyrock's failure to advance or lend against
a specific Receivable affect or limit Greyrock's security interest and other
rights therein.  Together with each such schedule and assignment, or later if
requested by Greyrock, Borrower shall furnish Greyrock with copies (or, at
Greyrock'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 Greyrock an
aged accounts receivable trial balance in such form and at such intervals as
Greyrock shall request.  In addition, Borrower shall deliver to Greyrock 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
endorsements.

  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
Greyrock, and Borrower shall deliver all such payments and proceeds to Greyrock,
within one business day after receipt of the same, in their original form, duly
endorsed, to be applied to the Obligations in such order as Greyrock shall
determine.

  4.5  Disputes.  Borrower shall notify Greyrock promptly of all disputes or
claims relating to Receivables on the regular reports to Greyrock.  Borrower
shall not forgive, or settle any Receivable for less than payment in

                                      -3-
<PAGE>

     Greyrock Capital                            Loan and Security Agreement
--------------------------------------------------------------------------------

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 Greyrock on the regular reports provided to Greyrock; (ii)
no Default or Event of Default has occurred and is continuing; and (iii) taking
into account all such settlements and forgiveness, the total outstanding Loans
and other Obligations will not exceed the Credit Limit.

  4.6  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 Greyrock).  In the event any attempted return occurs
after the occurrence of any Event of Default, Borrower shall (i) not accept any
return without Greyrock's prior written consent, (ii) hold the returned
Inventory in trust for Greyrock, (iii) segregate all returned Inventory from all
of Borrower's other property, (iv) immediately notify Greyrock of the return
of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Greyrock's request deliver such
returned Inventory to Greyrock.

  4.7  Verification.  Greyrock 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 Greyrock or such other name as Greyrock may choose, and Greyrock or
its designee may, at any time, notify Account Debtors that it has a security
interest in the Receivables.

  4.8  No Liability.  Greyrock 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 Greyrock 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 Greyrock from liability for
its own gross negligence or willful misconduct.

5.  ADDITIONAL DUTIES OF THE BORROWER.

  5.1  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 Greyrock, in such form and amounts as Greyrock
may reasonably require, and Borrower shall provide evidence of such insurance to
Greyrock, so that Greyrock is satisfied that such insurance is, at all times, in
full force and effect. * Upon receipt of the proceeds of any such insurance,
Greyrock shall apply such proceeds in reduction of the Obligations as Greyrock
shall determine in its sole discretion, except that, provided no Default or
Event of Default has occurred and is continuing, Greyrock 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.  Greyrock may
require reasonable assurance that the insurance proceeds so released will be so
used.  If Borrower fails to provide or pay for any insurance, Greyrock may, but
is not obligated to, obtain the same at Borrower's expense.  Borrower shall
promptly deliver to Greyrock copies of all reports made to insurance companies.

  * All liability insurance policies of Borrower shall name Greyrock as an
additional insured, and all property casualty and related insurance policies of
Borrower shall name Greyrock as a loss payee thereon and Borrower shall cause a
lenders loss payee endorsement in form reasonably acceptable to Greyrock to be
delivered to Greyrock.

  5.2  Reports.  Borrower, at its expense, shall provide Greyrock 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 Greyrock shall from time to time reasonably
specify.

  5.3  Access to Collateral, Books and Records.  At reasonable times, and on one
business day's notice, Greyrock, or its agents, shall have the right to inspect
the Collateral, and the right to audit and copy Borrower's books and records.
Greyrock shall take reasonable steps to keep confidential all information
obtained in any such inspection or audit, but Greyrock 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
Greyrock's then current standard charge for the same), plus reasonable out-of-
pockets expenses.  Borrower shall not be charged more than $3,000 per audit
(plus reasonable out-of-pockets expenses), nor shall audits be done more
frequently than four times per calendar year, provided that the foregoing limits
shall not apply after the occurrence of a Default or Event of Default, nor shall
they restrict Greyrock's right to conduct audits at its own expense (whether or
not a Default or Event of Default has occurred).  * 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 Greyrock's written consent, which may be conditioned
upon such accounting firm, service bureau or other third party

agreeing to give Greyrock the same rights with respect to access to books and
records and related rights as Greyrock has under this Agreement.

  * With the exception of books and records more than three years old,

disposition of any Collateral shall be delivered, in kind, by Borrower to
Greyrock 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 Greyrock shall determine; provided that, if no
Default or Event of Default has occurred and is continuing, and if no term loan
is outstanding hereunder, then Borrower shall not be obligated to remit to
Greyrock the proceeds of the sale of Equipment which is sold in the ordinary
course of business, in a good-faith arm's length transaction.  Except for the
proceeds of the sale of Equipment as set forth above, Borrower shall not
commingle proceeds of Collateral with any of Borrower's other funds or property,
and shall hold such proceeds separate and apart from such other funds and
property and in an express trust for Greyrock.  Nothing in this Section limits
the restrictions on disposition of Collateral set forth elsewhere in this
Agreement.

general account of Borrower or which are transmitted or turned over to Greyrock
on account of the Obligations, except that Borrower may issue guarantees in the
ordinary course of its business in an aggregate amount at any one time

business.

5.5

  5.6  Litigation Cooperation.  Should any third-party suit or proceeding be
instituted by or against Greyrock with respect to any Collateral or in any
manner relating to Borrower, Borrower shall, without expense to Greyrock, make

Greyrock harmless from and against any and all claims, debts, liabilities,
demands, obligations, actions, causes of action, penalties, costs and expenses
(including attorneys' fees), of every nature, character and description *, which
Greyrock may sustain or incur based upon or arising out of any of the
Obligations, any actual or alleged failure to collect and pay over any

Greyrock to comply with any writ of attachment or other legal process relating
to Borrower or any of its property, or any other matter, cause or thing

the result of the gross negligence or willful misconduct of Greyrock or any of
its directors, officers, employees, agents, attorneys, or any other person

6.  TERM.

  6.1  Maturity Date.  This Agreement shall continue in effect until the
maturity date set forth on the Schedule (the Maturity Date); provided that the
Maturity Date shall automatically be extended, and this Agreement shall
automatically and continuously renew, for successive additional terms of one
year each, unless one party gives written notice to the other, not less than
sixty days prior to the next Maturity Date, that such party elects to terminate
this Agreement effective on the next Maturity Date.

  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 Greyrock; or (ii) by Greyrock at any
time after the occurrence of an Event of Default, without notice, effective
immediately.  If this Agreement is terminated by Borrower or by Greyrock under
this Section 6.2, Borrower shall pay to Greyrock a termination fee (the
Termination Fee) in the amount shown on the Schedule.  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.

  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 based upon an application, guarantee, indemnity or similar
agreement on the part of Greyrock, then on such date Borrower shall provide to
Greyrock cash collateral in an amount equal to 110% of the face amount of all
such letters of credit plus all interest, fees and costs due or (in Greyrock's
estimation) likely to become due in connection therewith, to secure all of the
Obligations relating to said letters of credit, pursuant to Greyrock's then
standard form cash pledge agreement.  Notwithstanding any termination of this
Agreement, all of Greyrock'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
Greyrock, Greyrock 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 Greyrock, nor shall any such termination relieve Borrower of any
Obligation to Greyrock, 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, Greyrock shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be reasonably required to terminate Greyrock's security interests.

7.  EVENTS OF DEFAULT AND REMEDIES.

  7.1  Events of Default.  The  occurrence of any of the following events shall
constitute an Event of Default under this Agreement, and Borrower shall give

obligation secured by a Permitted Lien, which is not cured within any applicable

commenced; or (k) revocation or termination of, or limitation or denial of
liability upon, any guaranty of the Obligations or any attempt to do any of the

Obligations, or any attempt to do any of the foregoing, or commencement of

insolvency law; or (m) Borrower makes any payment on account of any indebtedness
or obligation which has been subordinated to the Obligations other than as
permitted in the applicable subordination agreement, or if any Person who has
subordinated such indebtedness or obligations terminates or in any way limits or
terminates its subordination agreement; or (n) there shall be a change in the
record or beneficial ownership of an aggregate of more than 20% of the
outstanding shares of stock of Borrower, in one or more transactions, compared
to the ownership of outstanding shares of stock of Borrower in effect on the
date hereof, without the prior written consent of Greyrock; or (o) Borrower
shall generally not pay its debts as they become due, or Borrower shall conceal,

extending credit to Borrower under this Agreement or any other document or
agreement; (b) Accelerate and declare all or

                                      -7-

     Greyrock Capital                            Loan and Security Agreement
--------------------------------------------------------------------------------

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 Greyrock without judicial process to enter onto any of 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 for so long
as Greyrock deems it reasonably necessary in order to complete the enforcement
of its rights under this Agreement or any other agreement; provided, however,
that should Greyrock seek to take possession of any of the Collateral by Court
process, Borrower hereby irrevocably waives: (i) any bond and any surety or
security relating thereto required by any statute, court rule or otherwise as an
incident to such possession; (ii) any demand for possession prior to the
commencement of any suit or action to recover possession thereof; and (iii) any
requirement that Greyrock retain possession of, and not dispose of, any such
Collateral until after trial or final judgment; (d) Require Borrower to assemble
any or all of the Collateral and make it available to Greyrock at places
designated by Greyrock which are reasonably convenient to Greyrock and Borrower,
and to remove the Collateral to such locations as Greyrock may deem advisable;
(e) Complete the processing, manufacturing or repair of any Collateral prior to
a disposition thereof and, for such purpose and for the purpose of removal,
Greyrock shall have the right to use Borrower's premises, vehicles, hoists,
lifts, cranes, equipment and all other property without charge; (f) Collect,
receive, dispose of and realize upon any Investment Property, including
withdrawal of any and all funds from any securities accounts; (g) Sell, lease or
otherwise dispose of any of the Collateral, in its condition at the time
Greyrock 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. Greyrock shall have the right to conduct such disposition on
Borrower's premises without charge, for such time or times as Greyrock deems
reasonable, or on Greyrock's premises, or elsewhere and the Collateral need not
be located at the place of disposition. Greyrock 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; (h) Demand payment
of, and collect any Receivables and General Intangibles comprising Collateral
and, in connection therewith, Borrower irrevocably authorizes Greyrock to
endorse or sign Borrower's name on all collections, receipts, instruments and
other documents, to take possession of and open mail addressed to Borrower and
remove therefrom payments made with respect to any item of the Collateral or
proceeds thereof, and, in Greyrock's sole discretion, to grant extensions of
time to pay, compromise claims and settle Receivables, General Intangibles and
the like for less than face value; and (i) 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 Greyrock 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 Greyrock with respect to the foregoing shall be added to and become
part of the 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.

  *except that, prior or concurrently with the taking of the first of any of the
following actions, Greyrock shall give Borrower one general written notice
stating that Greyrock is "proceeding to exercise its rights and remedies" or
words to that effect

  7.3  Standards for Determining Commercial Reasonableness.  Borrower and
Greyrock 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 Greyrock,
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, Greyrock may (but is not obligated to) direct any
prospective purchaser to ascertain directly from Borrower any and all
information concerning the same.  Greyrock 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 and during the continuance of any
Event of Default, without limiting Greyrock's other rights and remedies,
Borrower grants to Greyrock an irrevocable power of attorney coupled with an
interest, authorizing and permitting Greyrock (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 Greyrock
agrees to exercise the following powers in a commercially reasonable manner:

--------------------------------------------------------------------------------

(a)  Execute on behalf of Borrower any documents that Greyrock may, in its sole
discretion, deem advisable in order to perfect and maintain Greyrock's security
interest in the Collateral, or in order to exercise a right of Borrower or
Greyrock, 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 Greyrock's Collateral or
in which Greyrock 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 Greyrock's possession; (e) Endorse all
checks and other forms of remittances received by Greyrock; (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 Greyrock the same rights
of access and other rights with respect thereto as Greyrock has under this
Agreement; (k) Execute and deliver to any securities intermediary or other
Person any entitlement order, account control agreement or other notice,
document or instrument with respect to any Investment Property, and (l) 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 reasonable
attorneys' fees incurred by Greyrock 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 Greyrock's rights under the foregoing
power of attorney or any of Greyrock's other rights under this Agreement be
deemed to indicate that Greyrock is in control of the business, management or
properties of Borrower.

     7.5  Application of Proceeds.  All proceeds realized as the result of any
sale or other disposition of the Collateral shall be applied by Greyrock first
to the reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by Greyrock 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 Greyrock shall determine in its sole
discretion. Any surplus shall be paid to Borrower or other persons legally
entitled thereto; Borrower shall remain liable to Greyrock for any deficiency.
If Greyrock, in its sole discretion, directly or indirectly enters into a
deferred payment or other credit transaction with any purchaser at any sale of
Collateral, Greyrock 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 Greyrock of the cash therefor.

     7.6  Remedies Cumulative.  In addition to the rights and remedies set forth
in this Agreement, Greyrock 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 Greyrock and Borrower, and all of such rights
and remedies are cumulative and none is exclusive. Exercise or partial exercise
by Greyrock of one or more of its rights or remedies shall not be deemed an
election, nor bar Greyrock from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Greyrock 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.

the Obligations, in such order and manner as Greyrock shall determine in its
sole discretion.

     9.3  Charges to Account. Greyrock may, in its discretion, require that
Borrower pay monetary Obligations in cash to Greyrock *, to Borrower's Loan
account, in which event they will bear interest at the same rate applicable to

account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on

notifies Greyrock in writing to the contrary within sixty days after each
account is rendered, describing the nature of any alleged errors or admissions.

--------------------------------------------------------------------------------

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 Greyrock 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 Greyrock 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 Greyrock shall not waive
or diminish any right of Greyrock 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 Greyrock shall be deemed to have been
waived by any act or knowledge of Greyrock or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Greyrock 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 Greyrock on which Borrower is or may in any way be liable, and notice of any
action taken by Greyrock, unless expressly required by this Agreement.

     9.9  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 Greyrock.

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

     9.11 Attorneys Fees and Costs.  Borrower shall reimburse Greyrock for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Greyrock, 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 Greyrock 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
Greyrock's security interest in, the Collateral; and otherwise represent
Greyrock in any litigation relating to Borrower.  If either Greyrock 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
Greyrock 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.

     9.12 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 Greyrock; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Greyrock, and any prohibited
assignment shall be void. No consent by Greyrock to any assignment shall release
Borrower from its liability for the Obligations.

     9.13 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.

     9.14 Limitation of Actions. Any claim or cause of action by Borrower
against Greyrock, 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 Greyrock, 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 Greyrock, or on any other person
authorized to accept service on behalf of Greyrock, 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 Greyrock in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

     9.15 Paragraph Headings; Construction. Paragraph headings are only used in
this Agreement for convenience. Borrower and Greyrock acknowledge that the

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 Greyrock or Borrower under any
rule of construction or otherwise.

     9.16   Governing Law; Jurisdiction; Venue.  This Agreement and all acts and
transactions hereunder and all rights and obligations of Greyrock and Borrower
shall be governed by the laws of the State of California.  As a material part of
the consideration to Greyrock to enter into this Agreement, Borrower (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Greyrock's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Los Angeles County;
(ii) consents to the jurisdiction and venue of any such court and consents to

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.  *

     *9.16A Confidentiality.  Greyrock covenants and agrees, on a continuing
basis, to use reasonable efforts (but in no event less than the same degree of
care that it exercises with respect to its own proprietary information of the
same types) to maintain the confidentiality of and not to disclose to any person
other than its officers, directors, attorneys and accountants, affiliates,
participants, prospective participants, assignees and prospective assignees, and
such other persons to whom Greyrock shall at any time be required to make such
disclosure in accordance with applicable law, any and all proprietary, trade
secret or confidential information provided to or received by Greyrock from or
on account of Borrower or any affiliate of Borrower, including business plans
and forecasts, non-public financial information, confidential or secret
processes, formulae, devices or contractual information, customer lists,

could reasonably be expected to have a material adverse impact on the business,
finances or operations of Borrower or its affiliates, provided, however, the
                                                      --------  -------
foregoing provisions shall not be effective regarding the disposition of
Collateral after an Event of Default.

     9.17   Mutual Waiver of Jury Trial. BORROWER AND GREYROCK 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

OMISSIONS OF GREYROCK OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS,

                          as defined, is unavailable, "Prime Rate" shall mean

                          Street Journal on the first business day of the month,

extent that the Unregistered Copyrights must be registered to be enforced);

          (b)  Except for the security interest granted hereby and the non-

in the ordinary course of business of Grantor, Grantor is (and upon creation of
all future Copyrights, will be) the sole and exclusive owner of the entire and

States Copyright Office prior to the date Grantor requests or accepts any loan
from Greyrock with respect to such Receivables and prior to the date Grantor
includes any such Receivables in any accounts receivable aging, borrowing base
report or certificate or other similar report provided to Greyrock*, and Grantor
shall provide to Greyrock copies of all such registrations promptly upon the
receipt of the same.

applications for registration of all of its present software with the United
States Copyright Office (as provided in the Schedule to the Loan Agreement), and
during such 45-day period, and thereafter provided that said applications  duly

     3.   Covenants.  Until all of the Obligations have been satisfied in full
          ---------
and the Loan Agreement has terminated:

          (a)  Grantor shall not grant a security interest in any of the
Copyrights or other Collateral to any other person and shall not enter into any
agreement or take any action that is inconsistent with Grantor's obligations
hereunder or Grantor's other Obligations or would impair Greyrock's rights,
under this Agreement or otherwise, without Greyrock's prior written consent.

          (b)  Grantor shall ensure that each use of the Copyrights described in
Section 1 of this Agreement carries a complete and accurate copyright notice.

          (c)  Grantor shall use its best efforts to preserve and defend
Grantor's rights in the Copyrights unless Grantor, with the concurrence of
Greyrock, reasonably determines that a Copyright is not worth preserving or
defending.

          (d)  Grantor shall undertake all reasonable measures to cause its
employees, agents and independent contractors to assign to Grantor all rights of
authorship to any copyrighted material in which Grantor has or may subsequently
acquire any right or interest.

     4.   License Rights.  Grantor may license or sublicense the Copyrights
          --------------
only in the ordinary course of business and only on a non-exclusive basis, and
only to the extent of Grantor's rights and subject to Greyrock's security
interest and Grantor's obligations under this Agreement.

     5.   Greyrock May Supplement.  Grantor authorizes Greyrock to modify this
          -----------------------
Agreement by amending Schedule A or B to include any future copyrights to be
included in the Copyrights. Grantor shall from time to time update the lists of
Registered Copyrights and Unregistered Copyrights on Schedules A and B and lists
of License Agreements on Schedule C as Grantor obtains or acquires copyrights or
grants or obtains licenses in the future. Notwithstanding the foregoing, no
failure to so modify this Agreement or amend Schedules A or B or C shall in any
way affect, invalidate or detract from Greyrock's continuing security interest
in all Copyrights, whether or not listed on Schedule A or B and all license
agreements whether or not listed on Schedule C.

     6.   Default.  Upon an Event of Default (as defined in the Loan Agreement)
          -------
Greyrock shall have, in addition to all of its other rights and remedies under
the Loan Agreement, all rights and remedies of a secured party under the Uniform
Commercial Code (as enacted in any jurisdiction in which the Copyrights or other
Collateral are located or deemed to be located) or other applicable law. Upon
occurrence of an Event of Default, Grantor shall, upon request of Greyrock, give
written notice to all parties to the Licenses that all payments thereunder shall
be made to Greyrock, and Greyrock may itself give such notice.

     7.   Fees and Expenses.  On demand by Greyrock, without limiting any of the
          -----------------
terms of the Loan Agreement, Grantor shall pay all reasonable fees, costs, and
expenses (including without limitation reasonable attorneys' fees and legal
expenses) incurred by Greyrock in connection with (a) preparing this Agreement
and all other documents relating to this Agreement, (b) consummating this
transaction, (c) filing or recording any documents (including all taxes in
connection therewith) in public offices; and (d) paying or discharging any
taxes, counsel fees, maintenance fees, encumbrances, or other amounts in
connection with protecting, maintaining, or preserving the Copyrights or
defending or prosecuting any actions or proceedings arising out of or related to
the Copyrights.

     8.   Greyrock's Rights.  In the event that Grantor fails to use its best
          -----------------
efforts to preserve and defend Grantor's rights in the Copyrights (except as
permitted by paragraph 3(c) hereof) within a reasonable period of time after
learning of the existence of any actual or threatened infringement thereof, upon
twenty (20) days prior written notice to Grantor, Greyrock shall have the right,
but shall in no way be obligated to, bring suit or take any other action, in its
own name or in Grantor's name, to enforce or preserve Greyrock's or Grantor's
rights in the Copyrights.

                                      -3-
<PAGE>

Grantor shall at the request of Greyrock and at Grantor's expense do any lawful
acts and execute any documents requested by Greyrock to assist with such
enforcement. In the event Grantor has not taken action to enforce or preserve
Greyrock's and Grantor's rights in the Copyrights and Greyrock thereupon takes
such action, Grantor, upon demand, shall promptly reimburse and indemnify
Greyrock for all costs and expenses incurred in the exercise of Greyrock's or
Grantor's rights under this Section 8.

     9.   No Waiver.  No course of dealing between Grantor and Greyrock, nor
          ---------
any failure to exercise nor any delay in exercising, on the part of Greyrock,
any right, power, or privilege under this Agreement or under the Loan Agreement
or any other agreement, shall operate as a waiver.  No single or partial
exercise of any right, power, or privilege under this Agreement or under the
Loan Agreement or any other agreement by Greyrock shall preclude any other or
further exercise of such right, power, or privilege or the exercise of any other
right, power, or privilege by Greyrock.

     10.  Rights Are Cumulative.  All of Greyrock's rights and remedies with
          ---------------------
respect to the Copyrights and other Collateral whether established by this
Agreement, the Loan Agreement, or any other documents or agreements, or by law
shall be cumulative and may be exercised concurrently or in any order.

     11.  Copyright Office.  At the request of Greyrock, Grantor shall execute
          ----------------
any further documents necessary or appropriate to create and perfect Greyrock's
security interest in the Copyrights, including without limitation any documents
for filing with the United States Copyright Office and/or any applicable state
office. Greyrock may record this Agreement, an abstract thereof, or any other
document describing Greyrock's interest in the Copyrights with the United States
Copyright Office, at the expense of Grantor.

     12.  Indemnity.  Grantor shall protect, defend, indemnify, and hold
          ---------
harmless Greyrock and Greyrock's assigns from all liabilities, losses, and costs
(including without limitation reasonable attorneys' fees) incurred or imposed on
Greyrock relating to the matters in this Agreement, including, without
limitation, in connection with Greyrock's defense of any infringement action
brought by a third party against Greyrock.

     13.  Severability.  The provisions of this Agreement are severable. If any
          ------------
provision of this Agreement is held invalid or unenforceable in whole or in part
in any jurisdiction, then such invalidity or unenforceability shall affect only
such provision, or part thereof, in such jurisdiction, and shall not in any
manner affect such provision or part thereof in any other jurisdiction, or any
other provision of this Agreement in any jurisdiction.

     14.  Amendments; Entire Agreement.  This Agreement is subject to
          ----------------------------
modification only by a writing signed by the parties, except as provided in
Section 5 of this Agreement.  To the extent that any provision of this Agreement
conflicts with any provision of the Loan Agreement, the provision giving
Greyrock greater rights or remedies shall govern, it being understood that the
purpose of this Agreement is to add to, and not detract from, the rights granted
to Greyrock under the Loan Agreement.  This Agreement, the Loan Agreement, and
the documents relating thereto comprise the entire agreement of the parties with
respect to the matters addressed in this Agreement.

     15.  Further Assurances.  At Greyrock's request, Grantor shall execute and
          ------------------
deliver to Greyrock any further instruments or documentation, and perform any
acts, that may be reasonably necessary or appropriate to implement this
Agreement, the Loan Agreement or any other agreement, and the documents relating
thereto, including without limitation any instrument or documentation reasonably
necessary or appropriate to create, maintain, perfect, or effectuate Greyrock's
security interests in the Copyrights or other Collateral.

     16.  Release.  At such time as Grantor shall completely satisfy all of the
          -------
Obligations and the Loan Agreement shall be terminated, Greyrock shall execute
and deliver to Grantor all

                                      -4-
<PAGE>

assignments and other instruments as may be reasonably necessary or proper to
terminate Greyrock's security interest in the Copyrights, subject to any
disposition of the Copyrights which may have been made by Greyrock pursuant to
this Agreement. For the purpose of this Agreement, the Obligations shall be
deemed to continue if Grantor enters into any bankruptcy or similar proceeding
at a time when any amount paid to Greyrock could be ordered to be repaid as a
preference or pursuant to a similar theory, and shall continue until it is
finally determined that no such repayment can be ordered.

     17.  True and Lawful Attorney.  Grantor hereby appoints Greyrock as
          ------------------------
Grantor's true and lawful attorney, with full power of substitution, to do any
or all of the following, in the name, place and stead of Grantor: (a) execute
an abstract of this Agreement or any other document describing Greyrock's
interest in the Copyrights, for filing with the United States Copyright Office;
(b) execute any modification of this Agreement pursuant to Section 5 of this
Agreement; and (c) following an Event of Default (as defined in the Loan
Agreement) execute any assignments, notices or transfer documents for purposes
of transferring title or right to receive any of the Copyrights or other
Collateral to any person, including without limitation Greyrock.

     18.  Successors.  The benefits and burdens of this Agreement shall inure to
          ----------
the benefit of and be binding upon the respective successors and permitted
assigns of the parties; provided that Grantor may not transfer any of the
Collateral or any rights hereunder, without the prior written consent of
Greyrock, except as specifically permitted hereby.

     19.  Governing Law.  The validity and interpretation of this Agreement and
          -------------
the rights and obligations of the parties shall be governed by the laws of the
State of California, excluding its conflict of law rules to the extent such
rules would apply the law of another jurisdiction, and the United States.

     20.  Waiver of Right to Jury Trial.  Greyrock and Grantor 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: (i) this Agreement; or (ii) any other present or
future instrument or agreement between Greyrock and Grantor; or (iii) any
conduct, acts or omissions of Greyrock or Grantor or any of their directors,
officers, employees, agents, attorneys or any other persons affiliated with
Greyrock or Grantor; in each of the foregoing cases, whether sounding in
contract or tort or otherwise.

     WITNESS the execution hereof as of the date first written above.
