DATE:           APRIL 30, 1998

   THIS CROSS-CORPORATE CONTINUING GUARANTY is executed by the above-named
guarantors (jointly and severally, the "Guarantor"), as of the above date, in
favor of GREYROCK BUSINESS CREDIT, a Division of NationsCredit Commercial

above-named borrowers (jointly and severally, the "Borrower").

   1. CONTINUING GUARANTY. Guarantor hereby unconditionally guarantees and
promises to pay on demand to GBC in lawful money of the United States, and to
perform for the benefit of GBC, all of the Borrower's present and future
Indebtedness (as defined below) to GBC.

   2. "INDEBTEDNESS." As used in this Guaranty, the term "Indebtedness" is used
in its most comprehensive sense and shall mean and include without limitation:
(a) any and all debts, duties, obligations, liabilities, representations,
warranties and guaranties of Borrower or any one or more of them, heretofore,
now, or hereafter made, incurred, or created, whether directly to GBC or
acquired by GBC by assignment or otherwise, or held by GBC on behalf of others,
however arising, whether voluntary or involuntary, due or not due, absolute or
contingent, liquidated or unliquidated, certain or uncertain, determined or
undetermined, monetary or nonmonetary, written or oral, and whether Borrower may
be liable individually or jointly with others, and regardless of whether
recovery thereon may be or hereafter become barred by any statute of
limitations, discharged or uncollectible in any bankruptcy, insolvency or other
proceeding, or otherwise unenforceable; and (b) any and all amendments,
modifications, renewals and extensions of any or all of the foregoing, including
without limitation amendments, modifications, renewals and extensions which are
evidenced by any new or additional instrument, document or agreement; and (c)
any and all attorneys' fees, court costs, and collection charges incurred in
endeavoring to collect or enforce any of the foregoing against Borrower,
Guarantor, or any other person liable thereon (whether or not suit be brought)
and any other expenses of, for or incidental to collection thereof.

   3. WAIVERS. Guarantor hereby waives: (a) presentment for payment, notice of
dishonor, demand, protest, and notice thereof as to any instrument, and all
other notices and demands to which Guarantor might be entitled, including
without limitation notice of all of the following: the acceptance hereof; the
creation, existence, or acquisition of any Indebtedness; the amount of the
Indebtedness from time to time outstanding; any foreclosure sale or other
disposition of any property which secures any or all of the Indebtedness or
which secures the obligations of any other guarantor of any or all of the
Indebtedness; any adverse change in Borrower's financial position; any other
fact which might increase Guarantor's risk; any default, partial payment or
non-payment of all or any part of the Indebtedness; the occurrence of any other
Event of Default (as hereinafter defined); any and all agreements and
arrangements between GBC and Borrower and any changes, modifications, or
extensions thereof, and any revocation, modification or release of any guaranty
of any or all of the Indebtedness by any person (including without limitation
any other person signing this Guaranty); (b) any right to require GBC to
institute suit against, or to exhaust its rights and remedies against, Borrower
or any other person, or to proceed against any property of any kind which
secures all or any part of the Indebtedness, or to exercise any right of offset
or other right with respect to any reserves, credits or deposit accounts held by
or maintained with GBC or any indebtedness of GBC to Borrower, or to exercise
any other right or power, or pursue any other remedy GBC may have; (c) any
defense arising by reason of any disability or other defense of Borrower or any
other guarantor or any endorser, co-maker or other person, or by reason of the
cessation from

SILICON VALLEY BANK                            NOTES TO CROSS CORPORATE GUARANTY
--------------------------------------------------------------------------------



any cause whatsoever of any liability of Borrower or any other guarantor or any
endorser, co-maker or other person, with respect to all or any part of the
Indebtedness, or by reason of any act or omission of GBC or others which
directly or indirectly results in the discharge or release of Borrower or any
other guarantor or any other person or any Indebtedness or any security
therefor, whether by operation of law or otherwise; (d) any defense arising by
reason of any failure of GBC to obtain, perfect, maintain or keep in force any
security interest in, or lien or encumbrance upon, any property of Borrower or
any other person; (e) any defense based upon any failure of GBC to give
Guarantor notice of any sale or other disposition of any property securing any
or all of the Indebtedness, or any defects in any such notice that may be given,
or any failure of GBC to comply with any provision of applicable law in
enforcing any security interest in or lien upon any property securing any or all
of the Indebtedness including, but not limited to, any failure by GBC to dispose
of any property securing any or all of the Indebtedness in a commercially
reasonable manner; (f) any defense based upon or arising out of any bankruptcy,
insolvency, reorganization, arrangement, readjustment of debt, liquidation or
dissolution proceeding commenced by or against Borrower or any other guarantor
or any endorser, co-maker or other person, including without limitation any
discharge of, or bar against collecting, any of the Indebtedness (including
without limitation any interest thereon), in or as a result of any such
proceeding; and (g) the benefit of any and all statutes of limitation with
respect to any action based upon, arising out of or related to this Guaranty.
Until all of the Indebtedness has been paid, performed, and discharged in full,
nothing shall discharge or satisfy the liability of Guarantor hereunder except
the full performance and payment of all of the Indebtedness. If any claim is
ever made upon GBC for repayment or recovery of any amount or amounts received
by GBC in payment of or on account of any of the Indebtedness, because of any
claim that any such payment constituted a preferential transfer or fraudulent
conveyance, or for any other reason whatsoever, and GBC repays all or part of
said amount by reason of any judgment, decree or order of any court or
administrative body having jurisdiction over GBC or any of its property, or by
reason of any settlement or compromise of any such claim effected by GBC with
any such claimant (including without limitation the Borrower), then and in any
such event, Guarantor agrees that any such judgment, decree, order, settlement
and compromise shall be binding upon Guarantor, notwithstanding any revocation
or release of this Guaranty or the cancellation of any note or other instrument
evidencing any of the Indebtedness, or any release of any of the Indebtedness,
and the Guarantor shall be and remain liable to GBC under this Guaranty for the
amount so repaid or recovered, to the same extent as if such amount had never
originally been received by GBC, and the provisions of this sentence shall
survive, and continue in effect, notwithstanding any revocation or release of
this Guaranty. Until all of the Indebtedness has been irrevocably paid and
performed in full, Guarantor hereby expressly and unconditionally waives all
rights of subrogation, reimbursement and indemnity of every kind against
Borrower, and all rights of recourse to any assets or property of Borrower, and
all rights to any collateral or security held for the payment and performance of
any Indebtedness, including (but not limited to) any of the foregoing rights
which Guarantor may have under any present or future document or agreement with
any Borrower or other person, and including (but not limited to) any of the
foregoing rights which Guarantor may have under any equitable doctrine of
subrogation, implied contract, or unjust enrichment, or any other equitable or
legal doctrine. Neither GBC, nor any of its directors, officers, employees,
agents, attorneys or any other person affiliated with or representing GBC shall
be liable for any claims, demands, losses or damages, of any kind whatsoever,
made, claimed, incurred or suffered by Guarantor or any other party through the
ordinary negligence of GBC, or any of its directors, officers, employees,
agents, attorneys or any other person affiliated with or representing GBC.

   4. CONSENTS. Guarantor hereby consents and agrees that, without notice to or
by Guarantor and without affecting or impairing in any way the obligations or
liability of Guarantor hereunder, GBC may, from time to time before or after
revocation of this Guaranty, do any one or more of the following in GBC's sole
and absolute discretion: (a) accelerate, accept partial payments of, compromise
or settle, renew, extend the time for the payment, discharge, or performance of,
refuse to enforce, and release all or any parties to, any or all of the
Indebtedness; (b) grant any other indulgence to Borrower or any other person in
respect of any or all of the Indebtedness or any other matter; (c) accept,
release, waive, surrender, enforce, exchange, modify, impair, or extend the time
for the performance, discharge, or payment of, any and all property of any kind
securing any or all of the Indebtedness or any guaranty of any or all of the
Indebtedness, or on which GBC at any time may have a lien, or refuse to enforce
its rights or make any compromise or settlement or agreement therefor in respect
of any or all of such property; (d) substitute or add, or take any action or
omit to take any action which results in the release of, any one or more
endorsers or guarantors of all or any part of the Indebtedness, including,
without limitation one or more parties to this Guaranty, regardless of any
destruction or impairment of any right of contribution or other right of
Guarantor; (e) amend, alter or change in any respect whatsoever any term or
provision relating to any or all of the Indebtedness, including the rate of
interest thereon; (f) apply any sums received from Borrower, any other
guarantor, endorser, or co-signer, or from the disposition of any collateral or
security, to any indebtedness whatsoever owing from such person or secured by
such collateral or security, in such manner and order as GBC determines in its
sole discretion, and regardless of whether such indebtedness is part of the
Indebtedness, is secured, or is due and payable; (g) apply any sums received
from Guarantor or from the disposition of any collateral or security securing
the obligations of Guarantor, to any of the Indebtedness in such manner and
order as GBC determines in its sole discretion, regardless of whether or not
such Indebtedness is secured or is due and payable. Guarantor consents and
agrees that GBC shall be under no obligation to marshal any assets in favor of
Guarantor, or against or in payment of any or all of the Indebtedness. Guarantor
further consents and agrees that GBC shall have no duties or responsibilities
whatsoever with respect to any property securing any or all of the Indebtedness.
Without limiting the generality of the foregoing, GBC shall have no obligation
to monitor, verify, audit, examine, or obtain or maintain any insurance with
respect to, any property securing any or all of the Indebtedness.

   5. NO COMMITMENT. Guarantor acknowledges and agrees that acceptance by GBC of
this Guaranty shall not constitute a commitment of any kind by GBC to extend



                                      -2-
<PAGE>   3

such credit or other financial accommodation to Borrower or to permit Borrower
to incur Indebtedness to GBC.

   6. EXERCISE OF RIGHTS AND REMEDIES; FORECLOSURE OF TRUST DEEDS. Guarantor
hereby waives all rights of subrogation, reimbursement, indemnification, and
contribution and any other rights and defenses that are or may become available
to the Guarantor or other surety by reason of California Civil Code Sections
2787 to 2855, inclusive. The Guarantor waives all rights and defenses that the
Guarantor may have because the Borrower's Indebtedness is secured by real
property. This means, among other things: (1) GBC may collect from the Guarantor
without first foreclosing on any real or personal property collateral pledged by
the Borrower. (2) If GBC forecloses on any real property collateral pledged by
the Borrower: (A) The amount of the Indebtedness may be reduced only by the
price for which that collateral is sold at the foreclosure sale, even if the
collateral is worth more than the sale price. (B) GBC may collect from the
Guarantor even if GBC, by foreclosing on the real property collateral, has
destroyed any right the Guarantor may have to collect from the Borrower. This is
an unconditional and irrevocable waiver of any rights and defenses the Guarantor
may have because the Borrower's Indebtedness is secured by real property. These
rights and defenses include, but are not limited to, any rights or defenses
based upon Section 580a, 580b, 580d, or 726 of the Code of Civil Procedure. The
Guarantor waives all rights and defenses arising out of an election of remedies
by GBC, even though that election of remedies, such as a nonjudicial foreclosure
with respect to security for a guaranteed obligation, has destroyed the
Guarantor's rights of subrogation and reimbursement against the principal by the
operation of Section 580d of the Code of Civil Procedure or otherwise.

   7. ACCELERATION. Notwithstanding the terms of all or any part of the
Indebtedness, the obligations of the Guarantor hereunder to pay and perform all
of the Indebtedness shall, at the option of GBC, immediately become due and
payable, without notice, and without regard to the expressed maturity of any of
the Indebtedness, in the event: (a) Guarantor shall fail to pay or perform when
due any of its obligations under this Guaranty; or (b) any default or event of
default occurs under any present or future loan agreement or other instrument,
document, or agreement between GBC and Borrower or between GBC and Guarantor.
The foregoing are referred to in this Guaranty as "Events of Default".

   8. INDEMNITY. Guarantor hereby agrees to indemnify GBC and hold GBC harmless
from and against any and all claims, debts, liabilities, demands, obligations,
actions, causes of action, penalties, costs and expenses (including without
limitation attorneys' fees), of every nature, character and description, which
GBC may sustain or incur based upon or arising out of any of the Indebtedness,
any actual or alleged failure to collect and pay over any withholding or other
tax relating to Borrower or its employees, any relationship or agreement between
GBC and Borrower, any actual or alleged failure of GBC 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 whatsoever occurred, done, omitted
or suffered to be done by GBC relating in any way to Borrower or the
Indebtedness (except any such amounts sustained or incurred as the result of the
gross negligence or willful misconduct of GBC or any of its directors, officers,
employees, agents, attorneys, or any other person affiliated with or
representing GBC). Notwithstanding any provision in this Guaranty to the
contrary, the indemnity agreement set forth in this Section shall survive any
termination or revocation of this Guaranty and shall for all purposes continue
in full force and effect.

   9. SUBORDINATION. Any and all rights of Guarantor under any and all debts,
liabilities and obligations owing from Borrower to Guarantor, including any
security for and guaranties of any such obligations, whether now existing or
hereafter arising, are hereby subordinated in right of payment to the prior
payment in full of all of the Indebtedness. No payment in respect of any such
subordinated obligations shall at any time be made to or accepted by Guarantor
if at the time of such payment any Indebtedness is outstanding. If any Event of
Default has occurred, Borrower and any assignee, trustee in bankruptcy,
receiver, or any other person having custody or control over any or all of
Borrower's property are hereby authorized and directed to pay to GBC the entire
unpaid balance of the Indebtedness before making any payments whatsoever to
Guarantor, whether as a creditor, shareholder, or otherwise; and insofar as may
be necessary for that purpose, Guarantor hereby assigns and transfers to GBC all
rights to any and all debts, liabilities and obligations owing from Borrower to
Guarantor, including any security for and guaranties of any such obligations,
whether now existing or hereafter arising, including without limitation any
payments, dividends or distributions out of the business or assets of Borrower.
Any amounts received by Guarantor in violation of the foregoing provisions shall
be received and held as trustee for the benefit of GBC and shall forthwith be
paid over to GBC to be applied to the Indebtedness in such order and sequence as
GBC shall in its sole discretion determine, without limiting or affecting any
other right or remedy which GBC may have hereunder or otherwise and without
otherwise affecting the liability of Guarantor hereunder. Guarantor hereby
expressly waives any right to set-off or assert any counterclaim against
Borrower.

   10. REVOCATION. This is a Continuing Guaranty relating to all of the
Indebtedness, including Indebtedness arising under successive transactions which
from time to time continue the Indebtedness or renew it after it has been
satisfied. The obligations of Guarantor hereunder may be terminated only as to
future transactions and only by giving 90 days' advance written notice thereof
to GBC at its address above by registered first-class U.S. mail, postage
prepaid, return receipt requested. No such revocation shall be effective until
90 days following the date of actual receipt thereof by GBC. Notwithstanding
such revocation, this Guaranty and all consents, waivers and other provisions
hereof shall continue in full force and effect as to any and all Indebtedness
which is outstanding on the effective date of revocation and all extensions,
renewals and modifications of said Indebtedness (including without limitation
amendments, extensions, renewals and modifications which are evidenced by new or
additional instruments, documents or agreements executed after revocation), and
all interest thereon, then and thereafter accruing, and all attorneys' fees,
court costs and collection charges theretofore and thereafter incurred in
endeavoring to collect or enforce any of the foregoing against Borrower,
Guarantor or any other person liable thereon (whether or not suit be brought)
and any other expenses of, for or incidental to collection thereof.

   11. INDEPENDENT LIABILITY. Guarantor hereby agrees that one or more
successive or concurrent actions may be brought hereon against Guarantor, in the
same action in 



                                      -3-
<PAGE>   4

which Borrower may be sued or in separate actions, as often as deemed advisable
by GBC. The liability of Guarantor hereunder is exclusive and independent of any
other guaranty of any or all of the Indebtedness whether executed by Guarantor
or by any other guarantor (including without limitation any other persons
signing this Guaranty). The liability of Guarantor hereunder shall not be
affected, revoked, impaired, or reduced by any one or more of the following: (a)
the fact that the Indebtedness exceeds the maximum amount of Guarantor's
liability, if any, specified herein or elsewhere (and no agreement specifying a
maximum amount of Guarantor's liability shall be enforceable unless set forth in
a writing signed by GBC or set forth in this Guaranty); or (b) any direction as
to the application of payment by Borrower or by any other party; or (c) any
other continuing or restrictive guaranty or undertaking or any limitation on the
liability of any other guarantor (whether under this Guaranty or under any other
agreement); or (d) any payment on or reduction of any such other guaranty or
undertaking; or (e) any revocation, amendment, modification or release of any
such other guaranty or undertaking; or (f) any dissolution or termination of, or
increase, decrease, or change in membership of any Guarantor which is a
partnership. Guarantor hereby expressly represents that it was not induced to
give this Guaranty by the fact that there are or may be other guarantors either
under this Guaranty or otherwise, and Guarantor agrees that any release of any
one or more of such other guarantors shall not release Guarantor from its
obligations hereunder either in full or to any lesser extent.

   12. FINANCIAL CONDITION OF BORROWER. Guarantor is fully aware of the
financial condition of Borrower and is executing and delivering this Guaranty at
Borrower's request and based solely upon its own independent investigation of
all matters pertinent hereto, and Guarantor is not relying in any manner upon
any representation or statement of GBC with respect thereto. Guarantor
represents and warrants that it is in a position to obtain, and Guarantor hereby
assumes full responsibility for obtaining, any additional information concerning
Borrower's financial condition and any other matter pertinent hereto as
Guarantor may desire, and Guarantor is not relying upon or expecting GBC to
furnish to him any information now or hereafter in GBC's possession concerning
the same or any other matter.

   13. REPRESENTATIONS AND WARRANTIES. Guarantor hereby represents and warrants
that (i) it is in Guarantor's direct interest to assist Borrower in procuring
credit, because Borrower is an affiliate of Guarantor, furnishes goods or
services to Guarantor, purchases or acquires goods or services from Guarantor,
and/or otherwise has a direct or indirect corporate or business relationship
with Guarantor, (ii) this Guaranty has been duly and validly authorized,
executed and delivered and constitutes the valid and binding obligation of
Guarantor, enforceable in accordance with its terms, and (iii) the execution and
delivery of this Guaranty does not violate or constitute a default under (with
or without the giving of notice, the passage of time, or both) any order,
judgment, decree, instrument or agreement to which Guarantor is a party or by
which it or its assets are affected or bound.

   14. COSTS; INTEREST. Whether or not suit be instituted, Guarantor agrees to
reimburse GBC on demand for all reasonable attorneys' fees and all other
reasonable costs and expenses incurred by GBC in enforcing this Guaranty, or
arising out of or relating in any way to this Guaranty, or in enforcing any of
the Indebtedness against Borrower, Guarantor, or any other person, or in
connection with any property of any kind securing all or any part of the
Indebtedness. Without limiting the generality of the foregoing, and in addition
thereto, Guarantor shall reimburse GBC on demand for all reasonable attorneys'
fees and costs GBC incurs in any way relating to Guarantor, Borrower or the
Indebtedness, in order to: obtain legal advice; enforce or seek to enforce any
of its rights; commence, intervene in, respond to, or defend any action or
proceeding; file, prosecute or defend any claim or cause of action in any action
or proceeding (including without limitation any probate claim, bankruptcy claim,
third-party claim, secured creditor claim, reclamation complaint, and complaint
for relief from any stay under the Bankruptcy Code or otherwise); protect,
obtain possession of, sell, lease, dispose of or otherwise enforce any security
interest in or lien on any property of any kind securing any or all of the
Indebtedness; or represent GBC in any litigation with respect to Borrower's or
Guarantor's affairs. In the event either GBC or Guarantor files any lawsuit
against the other predicated on a breach of this Guaranty, the prevailing party
in such action shall be entitled to recover its attorneys' fees and costs of
suit from the non-prevailing party. All sums due under this Guaranty shall bear
interest from the date due until the date paid at the highest rate charged with
respect to any of the Indebtedness.

   15. NOTICES. Any notice which a party shall be required or shall desire to
give to the other hereunder (except for notice of revocation, which shall be
governed by Section 10 of this Guaranty) shall be given by personal delivery or
by telecopier or by depositing the same in the United States mail, first class
postage pre-paid, addressed to GBC at its address set forth in the heading of
this Guaranty and to Guarantor at its address provided by Guarantor to GBC in
writing, and such notices shall be deemed duly given on the date of personal
delivery or one day after the date telecopied or 3 business days after the date
of mailing as aforesaid. GBC and Guarantor may change their address for purposes
of receiving notices hereunder by giving written notice thereof to the other
party in accordance herewith. Guarantor shall give GBC immediate written notice
of any change in its address.

   16. CONSTRUCTION; SEVERABILITY. The term "Guarantor" as used herein shall be
deemed to refer to all and any one or more such persons and their obligations
hereunder shall be joint and several. As used in this Guaranty, the term
"property" is used in its most comprehensive sense and shall mean all property
of every kind and nature whatsoever, including without limitation real property,
personal property, mixed property, tangible property and intangible property. If
any provision of this Guaranty or the application thereof to any party or
circumstance is held invalid, void, inoperative or unenforceable, the remainder
of this Guaranty and the application of such provision to other parties or
circumstances shall not be affected thereby, the provisions of this Guaranty
being severable in any such instance.

   17. GENERAL PROVISIONS. GBC shall have the right to seek recourse against
Guarantor to the full extent provided for herein and in any other instrument or
agreement evidencing obligations of Guarantor to GBC, and against Borrower to
the full extent of the Indebtedness. No election in one form of action or
proceeding, or against any party, or on any obligation, shall constitute a
waiver of GBC's right to proceed in any other form of action or proceeding or
against any other party. The failure of GBC to enforce any of the provisions of
this Guaranty at any time or for any period of time shall not be construed to be
a waiver of any such provision or the right thereafter to enforce the same. All
remedies hereunder shall be cumulative and shall be in addition to all rights,
powers and remedies given to GBC by law or under any other instrument or
agreement. Time is of the essence in the performance by Guarantor of each and
every obligation under this Guaranty. GBC shall have no obligation to inquire
into the power or authority of Borrower or any of its officers, directors,
employees, or agents acting or purporting to act on its behalf, and any
Indebtedness made or created in reliance upon the professed exercise of any such
power or authority shall be included in the Indebtedness guaranteed hereby. This
Guaranty is the entire and only agreement between Guarantor and GBC with respect
to the guaranty of the Indebtedness of Borrower by Guarantor, and all
representations, warranties, agreements, or undertakings heretofore or
contemporaneously made, which are not set forth herein, are superseded hereby.
No course of dealings between the parties, no usage of the trade, and no parol
or extrinsic evidence of any nature shall be used or be relevant to supplement
or explain or modify any term or provision of this Guaranty. There are no
conditions to the full effectiveness of this Guaranty. The terms and provisions
hereof may not be waived, altered, modified, or amended except in a writing
executed by Guarantor and a duly authorized officer of GBC. All rights, benefits
and privileges hereunder shall inure to the benefit of and be enforceable by GBC
and its successors and assigns and shall be binding upon Guarantor and its
successors and assigns. Section headings are used herein for convenience only.
Guarantor acknowledges that the same may not describe completely the subject
matter of the applicable Section, and the same shall not be used in any manner
to construe, limit, define or interpret any term or provision hereof.

   18. GOVERNING LAW; VENUE AND JURISDICTION. This instrument and all acts and
transactions pursuant or relating hereto and all rights and obligations of the
parties hereto shall be governed, construed, and interpreted in accordance with
the internal laws of the State of California. In order to induce GBC to accept
this Guaranty, and as a material part of the consideration therefor, Guarantor
(i) agrees that all actions or proceedings relating directly or indirectly
hereto shall, at the option of GBC, be litigated in courts located within Los
Angeles County, California, (ii) consents to the jurisdiction of any such court
and consents to the service of



                                      -5-
<PAGE>   6

process in any such action or proceeding by personal delivery or any other
method permitted by law; and (iii) waives any and all rights Guarantor may have
to transfer or change the venue of any such action or proceeding.

   19. RECEIPT OF COPY. Guarantor acknowledges receipt of a copy of this
Guaranty.

   20. MUTUAL WAIVER OF RIGHT TO JURY TRIAL. GBC AND GUARANTOR HEREBY WAIVE THE
RIGHT TO TRIAL BY JURY IN ANY ACTION, CLAIM, LAWSUIT OR PROCEEDING BASED UPON,
ARISING OUT OF, OR IN ANY WAY RELATING TO: (i) THIS GUARANTEE OR ANY SUPPLEMENT
OR AMENDMENT THERETO; OR (ii) ANY OTHER PRESENT OR FUTURE INSTRUMENT OR
AGREEMENT BETWEEN GBC AND GUARANTOR ; OR (iii) ANY BREACH, CONDUCT, ACTS OR
OMISSIONS OF GBC OR GUARANTOR OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSON AFFILIATED WITH OR REPRESENTING
GBC OR GUARANTOR; IN EACH OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT
OR TORT OR OTHERWISE.
