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


SETTLEMENT AGREEMENT BETWEEN BORROWER AND DIGITAL EQUIPMENT CORPORATION DATED
DECEMBER 4, 1992 SHALL NOT REQUIRE THE CONSENT OF GBC.

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

    In order to induce GBC to enter into this Agreement and to make Loans,
Borrower represents and warrants to GBC 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 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 GBC 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.

    *10

     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 GBC 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.

     *10

     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. GBC 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 GBC and the Collateral against all claims of
others. So long as any Loan is outstanding which is a term loan, 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 GBC, use its best efforts to cause such third party to execute and
deliver to GBC, in form acceptable to GBC, such waivers and subordinations as
GBC shall specify, so as to ensure that GBC'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.

conducted, (ii) notifies GBC 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

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

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 GBC in

for any error, act, omission, or delay of any kind occurring in the settlement,

settling any Receivable in good faith for less than the full amount thereof, nor
shall GBC be deemed to be responsible for any of Borrower's obligations under

steps to keep confidential all information obtained in any such inspection or
audit, but GBC 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. [  *  ]* Borrower will not enter into any agreement with
any accounting firm, service bureau or third party to store Borrower's books or

has occurred and is continuing, and if no term loan is outstanding hereunder,
then Borrower shall not be obligated to remit to GBC 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 GBC.
Nothing in this Section limits the restrictions on disposition of Collateral set
forth elsewhere in this Agreement.

     5.5 NEGATIVE COVENANTS. Except as may be permitted in the Schedule,
Borrower shall not, without GBC's prior written consent, do any of the
following: (i) merge or consolidate with another corporation or entity*; (ii)
acquire any assets, except in the ordinary course of business**; (iii) enter
into any other transaction outside the ordinary course of business; (iv) sell or
transfer any Collateral, except that, provided no Default or Event of Default

    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 GBC; or (ii) by GBC at any time after
the occurrence* of an Event of Default, without notice, effective immediately.

    * AND DURING THE CONTINUANCE

    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 GBC, then on such date Borrower shall provide to GBC
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 GBC's estimation)
likely to become due in connection therewith, to secure all of the Obligations
relating to said letters of credit, pursuant to GBC's then standard form cash
pledge agreement. Notwithstanding any termination of this Agreement, all of
GBC'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 (LANGUAGE
INTENTIONALLY OMITTED) GBC 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 GBC, nor shall any such termination relieve
Borrower of any Obligation to GBC, 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, GBC shall promptly deliver to
Borrower termination statements, requests for reconveyances and such other

remain on the premises in exclusive control thereof, without charge for so long
as GBC deems it reasonably necessary in order to complete the enforcement of its
rights under this Agreement or any other agreement; provided, however, that
should GBC 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

adjourn any such sale from time to time without notice other than oral

directly or through any affiliated company purchase or lease any Collateral at

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 GBC 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

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.

     * (TO THE EXTENT THAT BORROWER HAS THE RIGHT TO ALLOW SUCH USE)

     ** REASONABLE

     7.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and GBC
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 GBC,
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, GBC may (but is not obligated t") direct any
prospective purchaser to ascertain directly from Borrower any and all
information concerning the same. GBC shall be free to employ other methods of
noticing and selling the Collateral, in its discretion, if they are commercially
reasonable. Without limiting the generality of the foregoing, Borrower
recognizes that GBC may be unable to make a public sale of any or all of the
Investment Property, by reason 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.

    7.4 POWER OF ATTORNEY. Upon the occurrence and during the continuance of any
Event of Default, without limiting GBC's other rights and remedies, Borrower
grants to GBC an irrevocable power of attorney coupled with an interest,
authorizing and permitting GBC (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 GBC agrees to exercise the
following powers in a commercially reasonable manner: (a) Execute on behalf of
Borrower any documents that GBC may, in its sole discretion, deem advisable in
order to perfect and maintain GBC's security interest in the Collateral, or in
order to exercise a right of Borrower or GBC, 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 GBC's Collateral or in which GBC 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 GBC's
possession; (e) Endorse all checks and other forms of remittances received by
GBC; (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 GBC the same rights of access and other rights with respect
thereto as GBC 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 GBC 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 GBC's rights under the
foregoing power of attorney or any of GBC's other rights under this Agreement be
deemed to indicate that GBC is in control of the business, management or
properties of Borrower.

    * BETWEEN GBC AND BORROWER

    ** BETWEEN GBC AND 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 GBC first to the
reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by GBC 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 GBC shall determine in its sole discretion. Any
surplus shall be paid to Borrower or other persons legally entitled thereto;
Borrower shall remain liable to GBC for any deficiency. If, GBC, in its sole
discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, GBC 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 GBC of the cash
therefor.

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

GBC and are consented to in writing by GBC (which consent shall not be
unreasonably withheld); (v) security interests being terminated substantially
concurrently with this Agreement; (vi) liens of materialmen, mechanics,

intercreditor agreement on GBC's then standard form, acknowledge that the
security interest is subordinate to the security interest in favor of GBC, and
agree not to take any action to enforce its subordinate security interest so
long as any Obligations remain outstanding, and that Borrower agree that any
uncured default in any obligation secured by the subordinate security interest
shall also constitute an Event of Default under this Agreement.

generally accepted accounting principles, consistently applied. All other terms
contained in this Agreement, unless otherwise indicated, shall have the meanings

9.  GENERAL PROVISIONS.

     9.1 INTEREST COMPUTATION. In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by GBC (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by GBC on account of the Obligations THREE Business Days after receipt
by GBC of immediately available funds. GBC shall not, however, be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to GBC in its discretion, and GBC may charge Borrower's Loan
account for the amount of any item of payment which is returned to GBC unpaid.

     9.2 APPLICATION OF PAYMENTS. All payments with respect to the Obligations
may be applied, and in GBC's sole discretion reversed and reapplied, to the
Obligations, in such order and manner as GBC shall determine in its sole
discretion.

     9.3 CHARGES TO ACCOUNT. GBC may, in its discretion, require that Borrower
pay monetary Obligations in cash to GBC, or charge them to Borrower's Loan
account, in which event they will bear interest at the same rate applicable to
the Loans.

    9.4 MONTHLY ACCOUNTINGS. GBC 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 GBC), unless Borrower notifies GBC in
writing to the contrary within sixty 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 facsimile, or by regular first-class mail, or certified mail
return receipt requested, addressed to GBC 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. All notices shall be deemed to have been given

of one business day following delivery to the private delivery service, or one
day after the date sent by facsimile, 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 GBC 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 GBC 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 GBC shall not waive or diminish
any right of GBC 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 GBC shall be deemed to have been waived by any act or knowledge of
GBC or its agents or employees, but only by a specific written waiver signed by
an authorized officer of GBC 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

held by GBC on which Borrower is or may in any way be liable, and notice of any
action taken by GBC, 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 GBC.

     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 GBC for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by GBC, 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
GBC incurs in order to do the following: prepare and negotiate this Agreement
and the documents relating to this Agreement; obtain legal advice in connection

protect, obtain possession of, lease, dispose of, or otherwise enforce GBC's
security interest in, the Collateral; and otherwise represent GBC in any
litigation relating to Borrower. If either GBC 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 t") 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 GBC may be entitled
pursuant to this Paragraph shall immediately become part of Borrower's

upon and inure to the benefit of the respective successors, assigns, heirs,
beneficiaries and representatives of Borrower and GBC and, as to Section 9.19
below, any participant of GBC; provided, however, that Borrower may not assign
or transfer any of its rights under this Agreement without the prior written
consent of GBC, and any prohibited assignment shall be void. No consent by GBC
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
GBC, its directors, officers, employees, agents, accountants or attorneys, based
upon, arising from, or relating to this 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 GBC, 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 GBC, or on any other person authorized to
accept service on behalf of GBC, 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 GBC in its sole discretion. This provision shall
survive any termination of this Agreement or any other present or future
agreement.

                         EMC, provided that (i) GBC does not believe the
                         collection thereof is insecure or may not be paid by
                         reason of EMC's financial inability to pay, (ii) GBC
                         has a first priority, valid, perfected security
                         interest therein, and (iii) such amounts are not
                         otherwise deemed ineligible on such credit and/or
                         collateral considerations as GBC in its good faith
                         discretion deems appropriate. Borrower hereby covenants
                         and agrees that it shall not agree to any amendment or
                         modification to the EMC Agreement without GBC's prior
                         written consent, which consent GBC shall not

7.  STREAMLINED AND NON-STREAMLINED FACILITIES
    (Section 4):

                     7.1 SELECTING A FACILITY. Throughout each calendar quarter,
                         either the "Streamlined Facilityo or the
                         "Non-Streamlined Facilityo shall be in effect, and
                         Borrower shall give GBC written notice, at least three
                         business days before the beginning of each calendar
                         quarter as to which Facility shall be in effect during
                         such calendar quarter. If Borrower fails to give
                         written notice to GBC at least three business days
                         before the beginning of a calendar quarter, as to which
                         Facility shall be in effect, then the Facility in
                         effect during the prior calendar quarter shall continue
                         in effect during the next calendar quarter. The
                         Facility in effect as of the Effective Date shall be
                         the Non-Streamlined Facility. If Borrower desires to
                         change from a Streamlined Facility to a Non-Streamlined
                         Facility, then along with the written notice of such
                         change, Borrower shall provide GBC with any schedules,
                         reports, assignments, agings and the like which would
                         be required under the new Facility but were not
                         required under the old Facility, current as of the date
                         of the change, and shall allow GBC access to its books
                         and records for purposes of GBC conducting its standard
                         pre-funding audit.

                     7.2 STREAMLINED FACILITY PROVISIONS.  At all times while
                         the Streamlined Facility is in effect, the following
                         provisions shall apply:

                         (A) Daily reporting of transactions and daily schedules
                         and assignments of Receivables and schedules of
                         collections, called for by Section 4.3 of the Loan
                         Agreement, will not be required. Instead, Borrower will
                         provide GBC with a weekly monthly Borrowing Base
                         Certificate, in such form as GBC shall from time to
                         time specify, within 3 days after the end of each week.
                         In the event, as of the end of any week, the total of
                         all Loans and all other Obligations exceeds the Credit
                         Limit, Borrower shall immediately pay the amount of the
                         excess to GBC.

                         (B) Delivery of the proceeds of Receivables and other
                         Collateral within one business day after receipt, as
                         called for by Sections 4.4 and 5.4 of the Loan
                         Agreement, will not be required.

                     7.3 TERMINATION OF STREAMLINED FACILITY Borrower shall have
                         the right to terminate the Streamlined Facility, as
                         provided above. In addition, the Streamlined Facility
                         shall immediately terminate if any Default or Event

                         of Default occurs and is continuing. Upon any
                         termination of the Streamlined Facility, Borrower
                         shall, then and thereafter, provide GBC with the daily
                         reporting of transactions and daily schedules and
                         assignments of Receivables and schedules of
                         collections, as called for by Section 4.3 of the Loan
                         Agreement, and Borrower shall deliver all proceeds of
                         Receivables and other Collateral to GBC, within one
                         business day after receipt, as called for by Sections
                         4.4 and 5.4 of the Loan Agreement.

                     between GBC and Borrower (as so amended, the "Prior Loan
                     Agreement") shall be amended and restated in its entirety
                     by the Loan and Security Agreement, and this Schedule
                     thereto, subject to the conditions precedent that no
                     Default or Event of Default has occurred or is continuing
                     under the Prior Loan Agreement, and GBC shall have received
                     each of the following, in form and substance satisfactory
                     to GBC and its counsel:

                           (A) the resolutions and other actions taken or
                           adopted by Borrower authorizing the execution,
                           delivery and performance of the Loan and Security
                           Agreement, this Schedule and any other documents and
                           instruments in connection therewith (the "Amendment
                           Documents"), and (B) the incumbency, authority and
                           signatures of each officer of Borrower authorized to

                     (iii) a Participation Agreement between GBC and Silicon

                           acquire a $10,000,000 participation interest in the
                           Loans; and

                     (iv)  evidence that all searches have been received and all
                           filings, registrations and recordings have been made
                           in the appropriate governmental offices, and all
                           other action has been taken, which shall be necessary
                           to confirm and continue GBC's first-priority
                           perfected and enforceable security interest in all of
                           the Collateral (other than the Collateral to be
                           released as provided below), subject only to the
                           Permitted Liens.

                      GBC shall notify Borrower and SVB of the date of
                      satisfaction of the foregoing conditions to effectiveness
                      (the "Effective Date"). Until the occurrence of the
                      Effective Date, the Prior Loan Agreement shall remain in
                      full force and effect and shall be unaffected hereby.

                      Securities, and the Pledge Agreement, the Guaranty and the

                      obligations which by their terms survive such termination,
                      such as indemnification obligations). In connection
                      therewith GBC will return all

                      original Pledged Securities and stock powers to Guarantor
                      and sign such other documents and take such other actions
                      as are reasonably necessary to accomplish the foregoing
                      termination, including termination of any UCC Financing
                      Statements in GBC's favor. (The foregoing capitalized
                      terms shall have the meanings set forth in the Amendment
                      to Loan Documents dated May 3, 1996, between Borrower and
                      GBC.)

                      Other than the foregoing release of the Pledged Securities
                      GBC's security interests in the Collateral created
                      pursuant to the Prior Loan Agreement shall be preserved
                      and continue in full force and effect notwithstanding the
                      amendment and restatement of the Prior Loan Agreement and
                      the occurrence of the Effective Date. GBC's execution and
                      delivery of, or acceptance of, the Amendment Documents
                      shall not be deemed to create a course of dealing or
                      otherwise create any express or implied duty by it to
                      provide any other or further amendments, consents or
                      waivers in the future. The Amendment Documents set forth
                      in full all of the representations and agreements of the
                      parties with respect to the subject matter thereof and
                      supersede all prior discussions, representations,
                      agreements and understandings between the parties with
                      respect to the subject thereof. All documents, instruments
                      and agreements between GBC and Borrower other than the
                      Prior Loan Agreement shall continue in full force and
