<PAGE>


Company other than the security interest granted by the Company to Silicon
Valley Bank, as described in SCHEDULE 2 attached hereto (the "PRIORITY
INTEREST").

      3.  REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS OF THE COMPANY.
The Company represents and warrants to, and covenants and agrees with, the
Secured Party as follows:

          (a) The Company has the requisite corporate power and authority to
enter into this Agreement and otherwise to carry out its obligations thereunder.
The execution, delivery and performance by the Company of this Agreement and the
filings contemplated therein have been duly authorized by all necessary action
on the part of the Company and no further action is required by the Company.

          (b) The Company is the sole owner of the Collateral (except for
non-exclusive licenses granted by the Company in the ordinary course of
business), free and clear of any liens, security interests, encumbrances, rights
or claims other than the Priority Interest, and is fully authorized to grant the
Security Interest in and to pledge the Collateral. No consent is required by
Silicon Valley Bank to enter into this Agreement or issue the Debentures or to
create the Security Interest hereunder that has not been received. There is not
on file in any governmental or regulatory authority, agency or recording office
an effective financing statement, security agreement, license or transfer or any
notice of any of the foregoing (other than those that have been filed in favor
of the Secured Party pursuant to this Agreement or with respect to the Priority
Interest) covering or affecting any of the Collateral. So long as this Agreement
shall be in effect, the Company shall not execute and shall not knowingly permit
to be on file in any such office or agency any such financing statement or other
document or instrument (except to the extent filed or recorded in favor of the
Secured Party pursuant to the terms of this Agreement or with respect to the
Priority Interest).

          (c) EXHIBIT A sets forth a true and complete list of all Copyrights
in existence as of the date of this Agreement. EXHIBIT B sets forth a true and

in the composition of the Collateral, including, without limitation, any
subsequent ownership rights of the Company in or to any Copyright, Patent or
Trademark.

          (d) Each of the Patents, Trademarks and Copyrights is valid and
enforceable, and no part of the Collateral has been judged invalid or
unenforceable. No written claim has been received that any of the Patents,
Trademarks or Copyrights or the Company's use of any Collateral violates the
rights of any third party. There has been no adverse decision to the Company's
claim of ownership rights in or exclusive rights to use the Collateral in any
jurisdiction or to the Company's right to keep and maintain such Collateral in
full force and effect, and there is no proceeding involving said rights pending
or, to the best knowledge of the Company, threatened before any court, judicial
body, administrative or regulatory agency, arbitrator or other governmental
authority.


                                     -3-

          (e) The Company shall at all times maintain its books of account and
records relating to the Collateral at its principal place of business and may
not relocate such books of account and records unless it delivers to the Secured
Party at least 30 days prior to such relocation (i) written notice of such
relocation and the new location thereof (which must be within the United States)
and (ii) evidence that appropriate financing statements and other necessary
documents have been filed and recorded and other steps have been taken to
perfect the Security Interest to create in favor of the Secured Party valid,
perfected and continuing liens in the Collateral subordinate only to the
Priority Interest. The principal place of business of the Company is located at
the address set forth in the introduction to this Agreement.

          (f) This Agreement creates in favor of the Secured Party a valid
security interest in the Collateral, including the Collateral listed on the
Exhibits hereto, securing the payment and performance of the Obligations, and,
upon making the filings described in the immediately following sentence, a
perfected security interest in such Collateral subordinate only to the Priority
Interest. The Security Interest is senior to all liens and encumbrances except
for the Priority Interest. Except for (x) the filing of this Agreement with the
United States Patent and Trademark Office with respect to the Patents and
Trademarks and the filing of this Agreement with the Register of Copyrights with
respect to the Copyrights, and (y) the filing of financing statements on Form-1
under the UCC with the jurisdictions indicated in SCHEDULE B, attached hereto,
no authorization or approval of or filing with or notice to any governmental
authority or regulatory body is required either (i) for the grant by the Company
of, or the effectiveness of, the Security Interest granted hereby or for the
execution, delivery and performance of this Agreement by the Company or (ii) for
the perfection of or exercise by the Secured Party of its rights and remedies
hereunder. The Company acknowledges and agrees that a copy of this Agreement (or
instruments executed and delivered pursuant hereto) will be filed and recorded
with each of the United States Patent and Trademark Office and the Register of
Copyrights with respect to the Patents, Trademarks and Copyrights that are now
or hereafter in existence.

          (g) On the date of execution of this Agreement, the Company will
deliver to the Secured Party (i) one or more executed UCC financing statements
on Form-1 with respect to the Security Interest for filing with the
jurisdictions indicated on SCHEDULE B, attached hereto and in such other
jurisdictions as may be requested by the Secured Party and (ii) one or more
executed recordation sheets relating to the filing and recording of this
Agreement with each of the United States Patent and Trademark Office and the
Register of Copyrights with respect to the Patents, Trademarks and Copyrights
that are now in existence.

          (h) The execution, delivery and performance of this Agreement does
not conflict with or cause a breach or default, or an event that with or without
the passage of time or notice, shall constitute a breach or default, under any
agreement to which the Company is a party or by the Company is bound. No consent
(including, without limitation, from stock holders or creditors of the Company)
is required for the Company to enter into and perform its obligations hereunder.


                                     -4-

          (i) The Company shall at all times maintain the liens and Security
Interest provided for hereunder as valid and perfected senior liens and security
interests in the Collateral in favor of the Secured Party, subordinate only to
the Priority Interest, until this Agreement and the Security Interest hereunder
shall terminated pursuant to Section 10. The Company hereby agrees to defend the
same against any and all persons. The Company shall safeguard and protect all
Collateral for the account of the Secured Party. At the request of the Secured
Party, the Company will sign and deliver to the Secured Party at any time or
from time to time one or more financing statements pursuant to the UCC (or any
other applicable statute) in form reasonably satisfactory to the Secured Party
and will pay the cost of filing the same in all public offices wherever filing
is, or is deemed by the Secured Party to be, necessary or desirable to effect
the rights and obligations provided for herein. Without limiting the generality
of the foregoing, the Company shall pay all fees, taxes and other amounts
necessary to maintain the Collateral and the Security Interest hereunder, and
the Company shall obtain and furnish to the Secured Party from time to time,
upon demand, such releases and/or subordinations of claims and liens which may
be required to maintain the priority of the Security Interest hereunder.

          (j) The Company will not allow any Collateral to be abandoned,
forfeited or dedicated to the public without the prior written consent of the
Secured Party. The Company will not transfer, pledge, hypothecate, encumber,
license (except for non-exclusive licenses granted by the Company in the
ordinary course of business), sell or otherwise dispose of any of the Collateral
without the prior written consent of the Secured Party.

          (k) The Company shall, within ten (10) days of obtaining knowledge
thereof, advise the Secured Party promptly, in sufficient detail, of any
substantial change in the Collateral, and of the occurrence of any event which
would have a material adverse effect on the value of the Collateral or on the
Secured Party's security interest therein.

          (l) The Company shall permit the Secured Party and its
representatives and agents to inspect the Collateral at any time, and to make
copies of records pertaining to the Collateral as may be requested by the
Secured Party from time to time.

          (m) The Company will take all steps reasonably necessary to
diligently pursue and seek to preserve, enforce and collect any rights, claims,
causes of action and accounts receivable in respect of the Collateral.

          (n) The Company shall promptly notify the Secured Party in
sufficient detail upon becoming aware of any attachment, garnishment, execution
or other legal process levied against any Collateral and of any other
information received by the Company that may materially affect the value of the
Collateral, the Security Interest or the rights and remedies of the Secured
Party hereunder.

subsidiaries of The Company.

      4.  DEFAULTS.  The following events shall be "EVENTS OF DEFAULT":

          (a)  The occurrence of an Event of Default (as defined in the
Debentures) under the Debentures;

          (b)  Any representation or warranty of the Company in this Agreement
or in the Security Agreement, dated the date hereof between the Company and the
Secured Party, shall prove to have been incorrect in any material respect when

          (c)  The failure by the Company to observe or perform any of its
obligations hereunder or in the Security Agreement, dated the date hereof
between the Company and the Secured Party, for ten (10) days after receipt by
the Company of notice of such failure from the Secured Party.

      5.  DUTY TO HOLD IN TRUST. Upon the occurrence of any Event of Default and
at any time thereafter, the Company shall, upon receipt by it of any revenue,
income or other sums subject to the Security Interest, whether payable pursuant
to the Debentures or otherwise, or of any check, draft, note, trade acceptance
or other instrument evidencing an obligation to pay any such sum, hold the same
in trust for the Secured Party and shall forthwith endorse and transfer any such
sums or instruments, or both, to the Secured Party for application to the
satisfaction of the Obligations.

      6.  RIGHTS AND REMEDIES UPON DEFAULT. Upon occurrence of any Event of
Default and at any time thereafter, the Secured Party shall have the right to
exercise all of the remedies conferred hereunder and under the Debentures, and
the Secured Party shall have all the rights and remedies of a secured party
under the UCC and/or any other applicable law (including the Uniform Commercial
Code of any jurisdiction in which any Collateral is then located). Without
limitation, the Secured Party shall have the following rights and powers:

          (a)  The Secured Party shall have the right to take possession of all

                                     -6-
<PAGE>


          (b)  The Secured Party shall have the right to operate the business
of the Company using the Collateral and shall have the right to assign, sell, or
otherwise dispose of and deliver all or any part of the Collateral, at public or
private sale or otherwise, either with or without special conditions or
stipulations, for cash or on credit or for future delivery, in such parcel or
parcels and at such time or times and at such place or places, and upon such
terms and conditions as the Secured Party may deem commercially reasonable, all
without (except as shall be required by applicable statute and cannot be waived)
advertisement or demand upon or notice to the Company or right of redemption of
the Company, which are hereby expressly waived. Upon each such sale, assignment
or other transfer of Collateral, the Secured Party may, unless prohibited by
applicable law which cannot be waived, purchase all or any part of the
Collateral being sold, free from and discharged of all trusts, claims, right of
redemption and equities of the Company, which are hereby waived and released.

          (c)  The Secured Party may license or, to the same extent the Company
is permitted by law and contract to do so, sub-license, whether or an exclusive
or non-exclusive basis, any of the Collateral throughout the world for such
term, on such conditions and in such manner as the Secured Party shall, in its
sole discretion, determine.

          (d)  The Secured Party may (without assuming any obligations or
liabilities thereunder), at any time, enforce (and shall have the exclusive

Company in, to and under any license agreement with respect to such Collateral,
and take or refrain from taking any action thereunder.

          (e)  The Secured Party may, in order to implement the assignment,
license, sale or other disposition of any of the Collateral pursuant to this
Section, pursuant to the authority provided for in Section 11, execute and
deliver on behalf of the Company one or more instruments of assignment of the
Collateral in form suitable for filing, recording or registration in any
jurisdictions as the Secured Party may determine advisable.

      7.  APPLICATIONS OF PROCEEDS; EXPENSES. (a) The proceeds of any such sale,
lease, license or other disposition of the Collateral hereunder shall be applied
first, to the expenses of retaking, holding, storing, processing and preparing
for sale, selling, and the like (including, without limitation, any taxes, fees
and other costs incurred in connection therewith) of the Collateral, to the
reasonable attorneys' fees and expenses incurred by the Secured Party in
enforcing its rights hereunder and in connection with collecting, storing and
disposing of the Collateral, and then to satisfaction of the Obligations, and to
the payment of any other amounts required by applicable law, after which the
Secured Party shall pay to the Company any surplus proceeds. If, upon the sale,
license or other disposition of the Collateral, the proceeds thereof are
insufficient to pay all amounts to which the Secured Party is legally entitled,
the Company will be liable for the deficiency, together with interest thereon,
at the rate of 15% per annum (the "DEFAULT RATE"), and the reasonable fees of
any attorneys employed by the Secured Party to collect such deficiency. To the
extent permitted by applicable law, the Company waives all claims, damages and
demands against the


                                     -7-
<PAGE>


Secured Party arising out of the repossession, removal, retention or sale of
the Collateral, unless due to the gross negligence or willful misconduct of
the Secured Party.

          (b)  The Company agrees to pay all out-of-pocket fees, costs and
expenses incurred in connection with any filing required hereunder, including,
without limitation, any financing statements, continuation statements, partial
releases and/or termination statements related thereto or any expenses of any
searches reasonably required by the Secured Party. The Company shall also pay
all other claims and charges which in the reasonable opinion of the Secured
Party might prejudice, imperil or otherwise affect the Collateral or the
Security Interest therein. The Company will also, upon demand, pay to the
Secured Party the amount of any and all reasonable expenses, including the
reasonable fees and expenses of its counsel and of any experts and agents, which
the Secured Party may incur in connection with (i) the enforcement of this
Agreement, (ii) the custody or preservation of, or the sale of, collection from,
or other realization upon, any of the Collateral, or (iii) the exercise or
enforcement of any of the rights of the Secured Party under the Debentures.
Until so paid, any fees payable hereunder shall be added to the principal amount
of the Debentures and shall bear interest at the Default Rate.

      8.  RESPONSIBILITY FOR COLLATERAL. The Company assumes all liabilities
and responsibility in connection with all Collateral, and the obligations of the
Company hereunder or under the Debentures shall in no way be affected or
diminished by reason of the loss, destruction, damage or theft of any of the
Collateral or its unavailability for any reason.

      9.  SECURITY INTEREST ABSOLUTE. All rights of the Secured Party and all
Obligations of the Company hereunder, shall be absolute and unconditional,
irrespective of: (a) any lack of validity or enforceability of this Agreement,
the Debentures or any agreement entered into in connection with the foregoing,
or any portion hereof or thereof; (b) any change in the time, manner or place of
payment or performance of, or in any other term of, all or any of the
Obligations, or any other amendment or waiver of or any consent to any departure
from the Debentures or any other agreement entered into in connection with the
foregoing; (c) any exchange, release or nonperfection of any of the Collateral,
or any release or amendment or waiver of or consent to departure from any other
collateral for, or any guaranty, or any other security, for all or any of the
Obligations; (d) any action by the Secured Party to obtain, adjust, settle and
cancel in its sole discretion any insurance claims or matters made or arising in
connection with the Collateral; or (e) any other circumstance which might
otherwise constitute any legal or equitable defense available to the Company, or
a discharge of all or any part of the Security Interest granted hereby. Until
the Obligations shall have been paid and performed in full, the rights of the
Secured Party shall continue even if the Obligations are barred for any reason,
including, without limitation, the running of the statute of limitations or
bankruptcy. The Company expressly waives presentment, protest, notice of
protest, demand, notice of nonpayment and demand for performance. In the event
that at any time any transfer of any Collateral or any payment received by the
Secured Party hereunder shall be deemed by final order of a court of competent
jurisdiction to have been a voidable preference or fraudulent conveyance under
the bankruptcy or insolvency laws of the United States, or shall be deemed to be
otherwise due to any party other than the Secured Party, then, in any such
event, the Company's obligations


                                     -8-
<PAGE>


hereunder shall survive cancellation of this Agreement, and shall not be
discharged or satisfied by any prior payment thereof and/or cancellation of
this Agreement, but shall remain a valid and binding obligation enforceable
in accordance with the terms and provisions hereof. The Company waives all
right to require the Secured Party to proceed against any other person or to
apply any Collateral which the Secured Party may hold at any time, or to
marshal assets, or to pursue any other remedy. The Company waives any defense
arising by reason of the application of the statute of limitations to any
obligation secured hereby.

      10. TERM OF AGREEMENT. This Agreement and the Security Interest shall
terminate on the date on which all payments under the Debentures have been made
in full and all other Obligations have been paid or discharged. Upon such
termination, the Secured Party, at the request and at the expense of the
Company, will join in executing any termination statement with respect to any
financing statement executed and filed pursuant to this Agreement.

      11. POWER OF ATTORNEY; FURTHER ASSURANCES. (a) The Company authorizes the
Secured Party, and does hereby make, constitute and appoint it, and its
respective officers, agents, successors or assigns with full power of
substitution, as the Company's true and lawful attorney-in-fact, with power, in
its own name or in the name of the Company, to, after the occurrence and during
the continuance of an Event of Default, (i) endorse any notes, checks, drafts,
money orders, or other instruments of payment (including payments payable under
or in respect of any policy of insurance) in respect of the Collateral that may
come into possession of the Secured Party; (ii) to sign and endorse any UCC
financing statement or any invoice, freight or express bill, bill of lading,
storage or warehouse receipts, drafts against debtors, assignments,
verifications and notices in connection with accounts, and other documents
relating to the Collateral; (iii) to pay or discharge taxes, liens, security
interests or other encumbrances at any time levied or placed on or threatened
against the Collateral; (iv) to demand, collect, receipt for, compromise, settle
and sue for monies due in respect of the Collateral; and (v) generally, to do,
at the option of the Secured Party, and at the Company's expense, at any time,
or from time to time, all acts and things which the Secured Party deems
necessary to protect, preserve and realize upon the Collateral and the Security
Interest granted therein in order to effect the intent of this Agreement and the
Debentures, all as fully and effectually as the Company might or could do; and
the Company hereby ratifies all that said attorney shall lawfully do or cause to
be done by virtue hereof. This power of attorney is coupled with an interest and
shall be irrevocable for the term of this Agreement and thereafter as long as
any of the Obligations shall be outstanding.

          (b)  On a continuing basis, the Company will make, execute,
acknowledge, deliver, file and record, as the case may be, in the proper filing
and recording places in any jurisdiction, including, without limitation, the
jurisdictions indicated on SCHEDULE B, attached hereto, all such instruments,
including appropriate financing and continuation statements and collateral
agreements and filings with the United States Patent and Trademark Office and
the Register of Copyrights, and take all such action as may reasonably be deemed
necessary or advisable, or as reasonably requested by the Secured Party, to
perfect the Security Interest granted hereunder and


                                     -9-
<PAGE>


otherwise to carry out the intent and purposes of this Agreement, or for
assuring and confirming to the Secured Party the grant or perfection of a
security interest in all the Collateral.

          (c)  The Company hereby irrevocably appoints the Secured Party as the
Company's attorney-in-fact, with full authority in the place and stead of the
Company and in the name of the Company, from time to time in the Secured Party's
discretion, to take any action and to execute any instrument which the Secured
Party may deem necessary or advisable to accomplish the purposes of this
Agreement, including:

               (i)  To modify, in its sole discretion, this Agreement without
first obtaining the Company's approval of or signature to such modification by
amending EXHIBIT A, EXHIBIT B and EXHIBIT C, hereof, as appropriate, to include
reference to any right, title or interest in any Copyrights, Patents or
Trademarks acquired by the Company after the execution hereof or to delete any
reference to any right, title or interest in any Copyrights, Patents or
Trademarks in which the Company no longer has or claims any right, title or
interest; and

               (ii) To file, in its sole discretion, one or more financing or
continuation statements and amendments thereto, relative to any of the
Collateral without the signature of the Company where permitted by law.

      12. NOTICES.  All notices, requests, demands and other communications
hereunder shall be in writing, with copies to all the other parties hereto,

      13. OTHER SECURITY. To the extent that the Obligations are now or
hereafter secured by property other than the Collateral or by the guarantee,
endorsement or property of any other person, firm, corporation or other entity,
then the Secured Party shall have the right, in its sole discretion, to pursue,
relinquish, subordinate, modify or take any other action with respect thereto,
without in any way modifying or affecting any of the Secured Party's rights and
remedies hereunder.

      14. MISCELLANEOUS.

          (a)  No course of dealing between the Company and the Secured Party,
nor any failure to exercise, nor any delay in exercising, on the part of the
Secured Party, any right, power or privilege hereunder or under the Debentures
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right, power or privilege hereunder or thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.

          (b)  All of the rights and remedies of the Secured Party with respect
to the Collateral, whether established hereby or by the Debentures or by any
other agreements, instruments or documents or by law shall be cumulative and may
be exercised singly or concurrently.

          (c)  This Agreement constitutes the entire agreement of the parties
with respect to the subject matter hereof and is intended to supersede all prior
negotiations, understandings and agreements with respect thereto. Except as
specifically set forth in this Agreement, no provision of this Agreement may be
modified or amended except by a written agreement specifically referring to this
Agreement and signed by the parties hereto.

          (d)  In the event that any provision of this Agreement is held to be
invalid, prohibited or unenforceable in any jurisdiction for any reason, unless
such provision is narrowed by judicial construction, this Agreement shall, as to
such jurisdiction, be construed as if such invalid, prohibited or unenforceable
provision had been more narrowly drawn so as not to be invalid,


                                    -11-

prohibited or unenforceable. If, notwithstanding the foregoing, any provision
of this Agreement is held to be invalid, prohibited or unenforceable in any
jurisdiction, such provision, as to such jurisdiction, shall be ineffective
to the extent of such invalidity, prohibition or unenforceability without
invalidating the remaining portion of such provision or the other provisions
of this Agreement and without affecting the validity or enforceability of
such provision or the other provisions of this Agreement in any other
jurisdiction.

          (e)  No waiver of any breach or default or any right under this
Agreement shall be considered valid unless in writing and signed by the party
giving such waiver, and no such waiver shall be deemed a waiver of any
subsequent breach or default or right, whether of the same or similar nature or
otherwise.

          (f)  This Agreement shall be binding upon and inure to the benefit of
each party hereto and its successors and assigns.

          (g)  Each party shall take such further action and execute and
deliver such further documents as may be necessary or appropriate in order to
carry out the provisions and purposes of this Agreement.

          (h)  All questions concerning the construction, validity, enforcement
and interpretation of this Agreement shall be governed by and construed and
enforced in accordance with the internal laws of the State of New York, without
regard to the principles of conflicts of law thereof. Each party agrees that all
legal proceedings concerning the interpretations, enforcement and defense of the
transactions contemplated by this Agreement (whether brought against a party
hereto or its respective affiliates, directors, officers, shareholders,
employees or agents) shall be commenced in the state and federal courts sitting
in the City of New York, Borough of Manhattan. Each party hereto hereby
irrevocably submits to the exclusive jurisdiction of the state and federal
courts sitting in the City of New York, Borough of Manhattan for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein (including with respect to
the enforcement of the any of this Agreement), and hereby irrevocably waives,
and agrees not to assert in any suit, action or proceeding, any claim that it is
not personally subject to the jurisdiction of any such court, that such suit,
action or proceeding is improper. Each party hereto hereby irrevocably waives
personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof via registered or certified
mail or overnight delivery (with evidence of delivery) to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. If either party shall commence
an action or proceeding to enforce any provisions of this Agreement, then the
prevailing party in such action or proceeding shall be reimbursed by the other
party for its attorneys fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such action or proceeding.

          (i)  EACH PARTY HERETO HEREBY AGREES TO WAIVE ITS RESPECTIVE RIGHTS
TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF
THIS AGREEMENT. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL ENCOMPASSING OF
ANY DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATER
OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH PARTY
HERETO ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT FOR EACH PARTY TO
ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH PARTY HAS ALREADY RELIED ON THIS
WAIVER IN ENTERING INTO THIS AGREEMENT AND THAT EACH PARTY WILL CONTINUE TO RELY
ON THIS WAIVER IN THEIR RELATED FUTURE DEALINGS. EACH PARTY FURTHER WARRANTS AND
REPRESENTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT
SUCH PARTY HAS KNOWINGLY AND VOLUNTARILY WAIVES ITS RIGHTS TO A JURY TRIAL
FOLLOWING SUCH CONSULTATION. THIS WAIVER IS IRREVOCABLE, MEANING THAT,
NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IT MAY NOT BE MODIFIED EITHER
ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
RENEWALS AND SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT. IN THE EVENT OF A
LITIGATION, THIS AGREEMENT MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE
COURT.

          (j)  This Agreement may be executed in any number of counterparts,
each of which when so executed shall be deemed to be an original and, all of
which taken together shall constitute one and the same Agreement. In the event
that any signature is delivered by facsimile transmission, such signature shall
create a valid binding obligation of the party executing (or on whose behalf
such signature is executed) the same with the same force and effect as if such
facsimile signature were the original thereof.
