<PAGE>

            (e) "Obligations" means all of the liabilities and obligations
(primary, secondary, direct, contingent, sole, joint or several) due or to
become due, or that are now or may be hereafter contracted or acquired, or owing
to, of any Debtor to the Secured Parties, including, without limitation, all
obligations under this Security Agreement, the Debentures, the Guaranty and any
other instruments, agreements or other documents executed and/or delivered in
connection herewith or therewith, in each case, whether now or hereafter
existing, voluntary or involuntary, direct or indirect, absolute or contingent,
liquidated or unliquidated, whether or not jointly owed with others, and whether
or not from time to time decreased or extinguished and later increased, created
or incurred, and all or any portion of such obligations or liabilities that are
paid, to the extent all or any part of such payment is avoided or recovered
directly or indirectly from any of the Secured Parties as a preference,
fraudulent transfer or otherwise as such obligations may be amended,
supplemented, converted, extended or modified from time to time. Without
limiting the generality of the foregoing, the term "Obligations" shall include,
without limitation: (i) principal of, and interest on the Debentures and the

limited to post-petition interest) in respect of the foregoing that would be

            (f) "Organizational Documents" means with respect to any Debtor, the
documents by which such Debtor was organized (such as a certificate of
incorporation, certificate of limited partnership or articles of organization,

and or any other applicable law of any state or states which has jurisdiction
with respect to all, or any portion of, the Collateral or this Security
Agreement, from time to time. It is the intent of the parties that defined terms
in the UCC should be construed in their broadest sense so that the term
"Collateral" will be construed in its broadest sense. Accordingly if there are,
from time to time, changes to defined terms in the UCC that broaden the
definitions, they are incorporated herein and if existing definitions in the UCC
are broader than the amended definitions, the existing ones shall be
controlling.

extend the loans as evidenced by the Debentures and to secure the complete and
timely payment, performance and discharge in full, as the case may be, of all of
the Obligations, the Company hereby unconditionally and irrevocably pledges,
grants and hypothecates to the Secured Parties a continuing and perfected (other
than as set forth herein) first priority security interest in and to, a lien
upon and a right of set off against all of its right, title and interest of
whatsoever kind and nature in and to, the Collateral, to the extent that
Citibank or PI (Cayman) Limited does not have a first priority security
interest.; and each Guarantor hereby unconditionally and irrevocably pledges,

                                       4

priority security interest in and to, a lien upon and a right of set off against
all of their respective right, title and interest of whatsoever kind and nature
in and to the Collateral (collectively with the security interest granted by the
Company, the "Security Interest").

      3. Delivery of Certain Collateral. Contemporaneously or prior to the
execution of this Security Agreement, each Debtor shall deliver or cause to be
delivered to the Agent (a) any and all certificates and other instruments
representing or evidencing the Pledged Securities, and (b) any and all
certificates and other instruments or documents representing any of the other

are, contemporaneously with the execution hereof, delivering to Agent, or have
previously delivered to Agent, a true and correct copy of each Organizational
Document governing any of the Pledged Securities.

      4. Representations, Warranties, Covenants and Agreements of the Debtors.
Each Debtor represents and warrants to, and covenants and agrees with, the
Secured Parties as follows:

            (a) Each Debtor has the requisite corporate, partnership, limited
liability company or other power and authority to enter into this Security
Agreement and otherwise to carry out its obligations hereunder. The execution,
delivery and performance by each Debtor of this Security Agreement and the
filings contemplated therein have been duly authorized by all necessary action
on the part of such Debtor and no further action is required by such Debtor.
This Security Agreement has been duly executed by each Debtor. This Security
Agreement constitutes the legal, valid and binding obligation of each Debtor,
enforceable against each Debtor in accordance with its terms except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization and similar laws of general application relating to or affecting
the rights and remedies of creditors and by general principles of equity.

            (b) The Debtors have no place of business or offices where their

interests, encumbrances, rights or claims, and are fully authorized to grant the
Security Interest. 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 will be filed in favor of the Secured Parties pursuant to this
Security Agreement) covering or affecting any of the Collateral. So long as this
Security Agreement shall be in effect, the Debtors 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 Parties pursuant to the terms of this
Security Agreement).

                                       5
<PAGE>

            (d) No written claim has been received that any Collateral or
Debtor's use of any Collateral violates the rights of any third party. There has
been no adverse decision to any Debtor's claim of ownership rights in or
exclusive rights to use the Collateral in any jurisdiction or to any Debtor'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 any
Debtor, threatened before any court, judicial body, administrative or regulatory
agency, arbitrator or other governmental authority.

            (e) Each Debtor shall at all times maintain its books of account and
records relating to the Collateral at its principal place of business and its
Collateral at the locations set forth on Schedule C attached hereto and may not
relocate such books of account and records or tangible Collateral unless it
delivers to the Agent, for the benefit of the Secured Parties, at least thirty
(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 under the UCC 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 Parties a valid,
perfected and continuing perfected lien in the Collateral, subject only to
Permitted Liens (as defined in the Debenture).

            (f) This Security Agreement creates in favor of the Secured Parties

securing the payment and performance of the Obligations. Upon making the filings
described in the immediately following paragraph, all security interests created
hereunder in any Collateral which may be perfected by filing Uniform Commercial
Code financing statements shall have been duly perfected. Except for the filing

immediately following paragraph, the recordation of the Intellectual Property
Security Agreement (as defined below) with respect to copyrights and copyright
applications in the United States Copyright Office referred to in paragraph
(mm), the execution and delivery of deposit account control agreements
satisfying the requirements of Section 9-104(a)(2) of the UCC with respect to
each deposit account of the Debtors, and the delivery of the certificates and
other instruments provided in Section 3, no action is necessary to create,
perfect or protect the security interests created hereunder with respect to
Collateral located in the U.S. Without limiting the generality of the foregoing,
except for the filing of said financing statements, the recordation of said
Intellectual Property Security Agreement, and the execution and delivery of said

(iii) the enforcement of the rights of the Secured Parties hereunder.

            (g) Each Debtor hereby authorizes the Agent on behalf of the Secured
Parties, or any of them, to file one or more financing statements under the UCC,
with respect to the Security Interest with the proper filing and recording

<PAGE>

            (h) The execution, delivery and performance of this Security
Agreement by the Debtors does not (i) violate any of the provisions of any
Organizational Documents of any Debtor or any judgment, decree, order or award
of any court, governmental body or arbitrator or any applicable law, rule or
regulation applicable to any Debtor or (ii) conflict with, or constitute a
default (or an event that with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment,
acceleration or cancellation (with or without notice, lapse of time or both) of,
any agreement, credit facility, debt or other instrument (evidencing any
Debtor's debt or otherwise) or other understanding to which any Debtor is a
party or by which any property or asset of any Debtor is bound or affected. No
consent (including, without limitation, from stockholders or creditors of any
Debtor) is required for any Debtor to enter into and perform its obligations
hereunder.

            (i) The capital stock and other equity interests listed on Schedule
H hereto represent all of the capital stock and other equity interests of the
Guarantors, and represent all capital stock and other equity interests owned,
directly or indirectly, by the Company. All of the Pledged Securities are
validly issued, fully paid and nonassessable, and the Company is the legal and
beneficial owner of the Pledged Securities, free and clear of any lien, security
interest or other encumbrance except for the security interests created by this
Security Agreement and other Permitted Liens (as defined in the Debenture).

            (j) The ownership and other equity interests in partnerships and
limited liability companies (if any) included in the Collateral (the "Pledged
Interests") by their express terms do not provide that they are securities
governed by Article 8 of the UCC and are not held in a securities account or by
any financial intermediary.

            (k) Each Debtor shall at all times maintain the liens and Security
Interest provided for hereunder as valid and perfected first priority liens and
security interests (except in the case of the Company to the extent that a first
priority lien is held by Citibank or PI (Cayman) Limitied, in which event the
Company shall maintain a perfected second priority lien) in the Collateral in
favor of the Secured Parties until this Security Agreement and the Security
Interest hereunder shall be terminated pursuant to Section 14 hereof. Each
Debtor hereby agrees to defend the same against the claims of any and all
persons and entities. Each Debtor shall safeguard and protect all Collateral for
the account of the Secured Parties.

      At the request of the Agent, each Debtor will sign and deliver to the
Agent at any time or from time to time one or more financing statements pursuant
to the UCC in form reasonably satisfactory to the Agent and will pay the cost of
filing the same in all public offices wherever filing is, or is deemed by the
Agent to be, necessary or desirable to effect the rights and obligations
provided for herein. Without limiting the generality of the foregoing, each
Debtor shall pay all fees, taxes and other amounts necessary to maintain the
Collateral and the Security Interest hereunder, and each Debtor shall obtain and
furnish to the Agent 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.

            (l) No Debtor will transfer, pledge, hypothecate, encumber, license,
sell or otherwise dispose of any of the Collateral (except for (i) non-exclusive
licenses granted by a Debtor in its ordinary course of business and (ii) sales
of inventory by a Debtor in its ordinary course of business), without the prior
written consent of a Majority in Interest.

                                       7
<PAGE>

            (m) Each Debtor shall keep and preserve its equipment, inventory and
other tangible Collateral in good condition, repair and order (ordinary wear and
tear excepted) and shall not operate or locate any such Collateral (or cause to
be operated or located) in any area excluded from insurance coverage.

            (n) Each Debtor shall maintain with financially sound and reputable
insurers, insurance with respect to the Collateral against loss or damage of the
kinds and in the amounts customarily insured against by entities of established
reputation having similar properties similarly situated and in such amounts as
are customarily carried under similar circumstances by other such entities and
otherwise as is prudent for entities engaged in similar businesses but in any
event sufficient to cover the full replacement cost thereof. Each Debtor shall
cause each insurance policy issued in connection herewith to provide, and the
insurer issuing such policy to certify to the Agent that (a) the Agent on behalf
of the Secured Parties will be named as lender loss payee and additional insured
under each such insurance policy; (b) if such insurance be proposed to be
cancelled or materially changed for any reason whatsoever, such insurer will
promptly notify the Agent and such cancellation or change shall not be effective
as to the Agent for at least thirty (30) days after receipt by the Agent of such
notice, unless the effect of such change is to extend or increase coverage under
the policy; and (c) the Agent will have the right (but no obligation) at its
election to remedy any default in the payment of premiums within thirty (30)
days of notice from the insurer of such default. If no Event of Default (as
defined in the Debenture) exists, and if the proceeds arising out of any claim
or series of related claims do not exceed $100,000, loss payments in each
instance will be applied by the applicable Debtor to the repair and/or
replacement of property with respect to which the loss was incurred to the
extent reasonably feasible, and any loss payments or the balance thereof
remaining, to the extent not so applied, shall be payable to the applicable
Debtor, provided, however, that payments received by any Debtor after an Event
of Default occurs and is continuing and if the proceeds arising out of any claim
or series of related claims do not exceed $100,000, shall be paid to the Agent,
for the benefit of the Secured Parties, and, if received by such Debtor, shall
be held in trust for and immediately paid over to the Agent, for the benefit of
the Secured Parties, unless otherwise directed in writing by the Agent. Copies
of such policies or the related certificates, in each case, naming the Agent, on
behalf of the Secured Parties, as lender loss payee and additional insured shall
be delivered to the Agent at least annually and at the time any new policy of
insurance is issued.

            (o) Each Debtor shall, within ten (10) days of obtaining knowledge
thereof, advise the Agent 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
Parties' security interest therein.

            (p) Each Debtor shall promptly execute and deliver to the Agent such
further deeds, mortgages, assignments, security agreements, financing statements
or other instruments, documents, certificates and assurances and take such
further action as the Agent may from time to time request and may in its sole
discretion deem necessary to perfect, protect or enforce its security interest
in the Collateral including, without limitation, if applicable, the execution

                                       8

hereof.

agents to inspect the Collateral any time to time, and to make copies of records
pertaining to the Collateral as may be requested by a Agent from time to time.

            (r) Each Debtor shall 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.

            (s) Each Debtor shall promptly notify the Agent 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
such Debtor that may materially affect the value of the Collateral, the Security
Interest or the rights and remedies of the Secured Parties hereunder.

            (t) All information heretofore, herein or hereafter supplied to the
Agent by or on behalf of any Debtor with respect to the Collateral is accurate

unless it provides at least thirty (30) days prior written notice to the Agent
of such change and, at the time of such written notification, such Debtor
provides any financing statements or fixture filings necessary to perfect and
continue perfected the perfected security Interest granted and evidenced by this
Security Agreement.

            (w) No Debtor may consign any of its Inventory without the consent
of a Majority in Interest which shall not be unreasonably withheld, except to
the extent such consignment or sale does not exceed 15% of the total value of
all of the Company's finished goods in Inventory. No Debtor may sell any of its
Inventory on bill and hold, sale or return, sale on approval, or other

any Debtor within the past five years except as set forth on Schedule E.

            (aa) At any time and from time to time that any Collateral consists
of instruments, certificated securities or other items that require or permit
possession by the secured party to perfect the security interest created hereby,
the applicable Debtor shall deliver such Collateral to the Agent, for the
benefit of the Secured Parties.

            (bb) Each Debtor, in its capacity as issuer, hereby agrees to comply
with any and all orders and instructions of the Agent regarding the Pledged
Interests consistent with the terms of this Security Agreement without the
further consent of any Debtor as contemplated by Section 8-106 (or any successor
section) of the UCC. Further, each Debtor agrees that it shall not enter into a
similar agreement (or one that would confer "control" within the meaning of
Article 8 of the UCC) with any other person or entity.

            (cc) Each Debtor shall cause all tangible chattel paper constituting
Collateral, to be delivered to the Agent, or, if such delivery is not possible,
then to cause such tangible chattel paper to contain a legend noting that it is
subject to the security interest created by this Security Agreement. To the
extent that any Collateral consists of electronic chattel paper, the applicable
Debtor shall cause the underlying chattel paper to be "marked" within the
meaning of Section 9-105 of the UCC (or successor section thereto).

            (dd) If there is any investment property or deposit account included
as Collateral that can be perfected by "control" through an account control
agreement, the applicable Debtor shall cause such an account control agreement,
in form and substance in each case satisfactory to the Agent, to be entered into
and delivered to the Agent, for the benefit of the Secured Parties.

            (ee) To the extent that any Collateral consists of letter-of-credit
rights, the applicable Debtor shall cause the issuer of each underlying letter
of credit to consent to an assignment of the proceeds thereof to the Secured
Parties.

            (ff) To the extent that any Collateral is in the possession of any
third party, the applicable Debtor shall join with the Agent in notifying such
third party of the Agent's security interest in such Collateral and shall use
its best reasonable efforts to obtain an acknowledgement and agreement from such
third party with respect to the Collateral, in form and substance satisfactory
to the Agent.

            (gg) If any Debtor shall at any time hold or acquire a commercial
tort claim, such Debtor shall promptly notify the Secured Parties in a writing
signed by such Debtor of the particulars thereof and grant to the Secured
Parties in such writing a security interest therein and in the proceeds thereof,

                                       10
<PAGE>

all upon the terms of this Security Agreement, with such writing to be in form
and substance satisfactory to the Secured Parties.

            (hh) Each Debtor shall immediately provide written notice to the
Agent of any and all accounts which arise out of contracts with any governmental
authority and, to the extent necessary to perfect or continue the perfected
status of the Security Interest in such accounts and proceeds thereof, shall
execute and deliver to the Agent, for the benefit of the Secured Parties, an
assignment of claims for such accounts and cooperate with the Agent in taking
any other steps required, in their judgment, under the Federal Assignment of
Claims Act or any similar federal, state or local statute or rule to perfect or
continue the perfected status of the Security Interest in such accounts and
proceeds thereof.

            (ii) Each Debtor shall cause each subsidiary of such Debtor
organized in the United States or any state thereof to immediately become a
party hereto (an "Additional Debtor"), by executing and delivering an Additional
Debtor Joinder in substantially the form of Annex A attached hereto and comply
with the provisions hereof applicable to the Debtors. Concurrent therewith, the
Additional Debtor shall deliver replacement schedules for, or supplements to all
other Schedules to (or referred to in) this Security Agreement, as applicable,
which replacement schedules shall supersede, or supplements shall modify, the
Schedules then in effect. The Additional Debtor shall also deliver such opinions
of counsel, authorizing resolutions, good standing certificates, incumbency
certificates, organizational documents, financing statements and other
information and documentation as the Secured Parties may reasonably request.
Upon delivery of the foregoing to the Agent, the Additional Debtor shall be and
become a party to this Security Agreement with the same rights and obligations
as the Debtors, for all purposes hereof as fully and to the same extent as if it
were an original signatory hereto and shall be deemed to have made the
representations, warranties and covenants set forth herein as of the date of
execution and delivery of such Additional Debtor Joinder, and all references
herein to the "Debtors" shall be deemed to include each Additional Debtor.

            (jj) Each Debtor shall vote the Pledged Securities to comply with
the covenants and agreements set forth herein and in the Debentures.

            (kk) Each Debtor shall register the pledge of the applicable Pledged
Securities on the books of such Debtor. Each Debtor shall notify each issuer of
Pledged Securities to register the pledge of the applicable Pledged Securities
in the name of the Secured Parties on the books of such issuer. Further, except
with respect to certificated securities delivered to the Agent, the applicable
Debtor shall deliver to the Agent an acknowledgement of pledge (which, where
appropriate, shall comply with the requirements of the relevant UCC with respect
to perfection by registration) signed by the issuer of the applicable Pledged
Securities, which acknowledgement shall confirm that: (a) it has registered the
pledge on its books and records; and (b) at any time directed by the Agent
during the continuation of an Event of Default, such issuer will transfer the
record ownership of such Pledged Securities into the name of any designee of the
Agent, will take such steps as may be necessary to effect the transfer, and will
comply with all other instructions of the Agent regarding such Pledged
Securities without the further consent of the applicable Debtor.

                                       11
<PAGE>

            (ll) In the event that, upon an occurrence of an Event of Default,
the Agent shall sell all or any of the Pledged Securities to another party or
parties (herein called the "Transferee") or shall purchase or retain all or any
of the Pledged Securities, each Debtor shall, to the extent applicable: (i)
deliver to the Agent or the Transferee, as the case may be, the articles of
incorporation, bylaws, minute books, stock certificate books, corporate seals,
deeds, leases, indentures, agreements, evidences of indebtedness, books of
account, financial records and all other Organizational Documents and records of
the Debtors and their direct and indirect subsidiaries; (ii) use its best
efforts to obtain resignations of the persons then serving as officers and
directors of the Debtors and their direct and indirect subsidiaries, if so
requested; and (iii) use its best efforts to obtain any approvals that are
required by any governmental or regulatory body in order to permit the sale of
the Pledged Securities to the Transferee or the purchase or retention of the
Pledged Securities by the Agent and allow the Transferee or the Agent to
continue the business of the Debtors and their direct and indirect subsidiaries.

            (mm) Without limiting the generality of the other obligations of the
Debtors hereunder, each Debtor shall promptly (i) cause to be registered at the
United States Copyright Office all of its material copyrights, (ii) cause the
security interest contemplated hereby with respect to all Intellectual Property
registered at the United States Copyright Office or United States Patent and
Trademark Office to be duly recorded at the applicable office, and (iii) give
the Agent notice whenever it acquires (whether absolutely or by license) or
creates any additional material Intellectual Property.

            (nn) Each Debtor will from time to time, at the joint and several
expense of the Debtors, promptly execute and deliver all such further
instruments and documents, and take all such further action as may be necessary
or desirable, or as the Agent may reasonably request, in order to perfect and
protect any security interest granted or purported to be granted hereby or to
enable the Agent, for the benefit of Secured Parties, to exercise and enforce
their rights and remedies hereunder and with respect to any Collateral or to
otherwise carry out the purposes of this Security Agreement.

            (oo) Schedule F attached hereto lists all of the patents, patent
applications, trademarks, trademark applications, registered copyrights, and
domain names owned by any of the Debtors as of the date hereof. Schedule F lists
all material licenses in favor of any Debtor for the use of any patents,
trademarks, copyrights and domain names as of the date hereof. All material
patents and trademarks of the Debtors have been duly recorded at the United
States Patent and Trademark Office and all material copyrights of the Debtors
have been duly recorded at the United States Copyright Office.

            (pp) Except as set forth on Schedule G attached hereto, none of the
account debtors or other persons or entities obligated on any of the Collateral
is a governmental authority covered by the Federal Assignment of Claims Act or
any similar federal, state or local statute or rule in respect of such
Collateral.

      5. Effect of Pledge on Certain Rights. If any of the Collateral subject to
this Security Agreement consists of nonvoting equity or ownership interests
(regardless of class, designation, preference or rights) that may be converted
into voting equity or ownership interests upon the occurrence of certain events
(including, without limitation, upon the transfer of all or any of the other

                                       12
<PAGE>

stock or assets of the issuer), it is agreed that the pledge of such equity or
ownership interests pursuant to this Security Agreement or the enforcement of
any of the Agent's rights hereunder shall not be deemed to be the type of event
which would trigger such conversion rights notwithstanding any provisions in the
Organizational Documents or agreements to which any Debtor is subject or to
which any Debtor is party.

      6. Defaults. The following events shall be "Events of Default":

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

            (b) Any representation or warranty of any Debtor in this Security
Agreement shall prove to have been incorrect when made;

            (c) The failure by any Debtor to observe or perform any of its
obligations hereunder for five (5) days after delivery to such Debtor of notice
of such failure by or on behalf of a Secured Party unless such default is
capable of cure but cannot be cured within such time frame and such Debtor is
using best efforts to cure same in a timely fashion; or

            (d) If any provision of this Security Agreement shall at any time
for any reason be declared to be null and void, or the validity or
enforceability thereof shall be contested by any Debtor, or a proceeding shall
be commenced by any Debtor, or by any governmental authority having jurisdiction
over any Debtor, seeking to establish the invalidity or unenforceability
thereof, or any Debtor shall deny that any Debtor has any liability or
obligation purported to be created under this Security Agreement.

      7. Duty To Hold In Trust.

            (a) Upon the occurrence of any Event of Default and at any time
thereafter, each Debtor shall, upon receipt of any revenue, income, dividend,
interest 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 Parties and shall forthwith endorse and
transfer any such sums or instruments, or both, to the Secured Parties, pro-rata
in proportion to their initial purchases of Debentures for application to the
satisfaction of the Obligations (and if any Debenture is not outstanding,
pro-rata in proportion to the initial purchases of the remaining Debentures).

            (b) If any Debtor shall become entitled to receive or shall receive
any securities or other property (including, without limitation, shares of
Pledged Securities or instruments representing Pledged Securities acquired after
the date hereof, or any options, warrants, rights or other similar property or
certificates representing a dividend, or any distribution in connection with any
recapitalization, reclassification or increase or reduction of capital, or
issued in connection with any reorganization of such Debtor or any of its direct
or indirect subsidiaries) in respect of the Pledged Securities (whether as an
addition to, in substitution of, or in exchange for, such Pledged Securities or
otherwise), such Debtor agrees to (i) accept the same as the agent of the
Secured Parties; (ii) hold the same in trust on behalf of and for the benefit of

                                       13
<PAGE>

the Secured Parties; and (iii) to deliver any and all certificates or
instruments evidencing the same to the Agent on or before the close of business
on the fifth business day following the receipt thereof by such Debtor, in the
exact form received together with the Necessary Endorsements, to be held by the
Agent subject to the terms of this Security Agreement as Collateral.

      8. Rights and Remedies Upon Default.

            (a) Upon the occurrence of any Event of Default and at any time
thereafter, the Agent, on behalf of the Secured Parties, shall have the right to
exercise all of the remedies conferred hereunder and under the Debenture. The
Agent, on behalf of the Secured Parties, shall have all the rights and remedies
of a secured party under the UCC. Without limitation, the Agent, on behalf of
the Secured Parties, shall have the following rights and powers:

                  (i) The Agent, for the benefit of the Secured Parties, shall
have the right to take possession of the Collateral and, for that purpose,
enter, with the aid and assistance of any person, any premises where the
Collateral, or any part thereof, is or may be placed and remove the same, and
each Debtor shall assemble the Collateral and make it available to the Agent at
places which the Agent shall reasonably select, whether at such Debtor's
premises or elsewhere, and make available to the Agent, without rent, all of
such Debtor's respective premises and facilities for the purpose of the Agent
taking possession of, removing or putting the Collateral in saleable or
disposable form.

                  (ii) Upon notice to the Debtors by the Agent, all rights of
each Debtor to exercise the voting and other consensual rights which it would
otherwise be entitled to exercise and all rights of each Debtor to receive the
dividends and interest which it would otherwise be authorized to receive and
retain, shall cease. Upon such notice, the Agent shall have the right to receive
any interest, cash dividends or other payments on the Collateral and, at the
option of the Agent, to exercise in the Agent's discretion all voting rights
pertaining thereto. Without limiting the generality of the foregoing, the Agent
shall have the right (but not the obligation) to exercise all rights with
respect to the Collateral as it were the sole and absolute owners thereof,
including, without limitation, to vote and/or to exchange, at its sole
discretion, any or all of the Collateral in connection with a merger,
reorganization, consolidation, recapitalization or other readjustment concerning
or involving the Collateral or any Debtor or any of its direct or indirect
subsidiaries.

                  (iii) The Agent, for the benefit of the Secured Parties, shall
have the right to operate the business of each Debtor using the Collateral and
shall have the right to assign, sell, lease 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 Agent 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 any Debtor or right of redemption of a Debtor, which are hereby expressly
waived. Upon each such sale, lease, assignment or other transfer of Collateral,
the Secured Parties 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 any
Debtor, which are hereby waived and released.

                                       14
<PAGE>

                  (iv) The Agent shall have the right (but not the obligation)
to notify any account debtors and any obligors under instruments or accounts to
make payments directly to the Agent, or the benefit of the Secured Parties, and
to enforce the Debtors' rights against such account debtors and obligors.

                  (v) The Agent may (but are not obligated to) direct any
financial intermediary or any other person or entity holding any investment
property to transfer the same to the Agent or their designee.

                  (vi) The Agent may (but are not obligated to) transfer any or
all Intellectual Property registered in the name of any Debtor at the United
States Patent and Trademark Office and/or Copyright Office into the name of the
Agent, for the benefit of the Secured Parties, or any designee or any purchaser
of any Collateral.

            (b) The Agent shall comply with any applicable law in connection
with a disposition of Collateral and such compliance will not be considered
adversely to affect the commercial reasonableness of any sale of the Collateral.
The Agent may sell the Collateral without giving any warranties and may
specifically disclaim such warranties. If the Agent sells any of the Collateral
on credit, the Debtors will only be credited with payments actually made by the
purchaser. In addition, each Debtor waives any and all rights that it may have
to a judicial hearing in advance of the enforcement of any of the Agent's rights
and remedies hereunder, including, without limitation, its right following an
Event of Default to take immediate possession of the Collateral and to exercise
its rights and remedies with respect thereto.

            (c) For the purpose of enabling the Agent to further exercise rights
and remedies under this Section 8 or elsewhere provided by agreement or
applicable law, each Debtor hereby grants to the Agent, for the benefit of the
Secured Parties, an irrevocable, nonexclusive license (exercisable without
payment of royalty or other compensation to such Debtor) to use, license or
sublicense following an Event of Default, any Intellectual Property now owned or
hereafter acquired by such Debtor, and wherever the same may be located, and
including in such license access to all media in which any of the licensed items
may be recorded or stored and to all computer software and programs used for the
compilation or printout thereof.

      9. Applications of Proceeds. The proceeds of any such sale, lease 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 Agent in enforcing their rights
hereunder and in connection with collecting, storing and disposing of the
Collateral, and then to satisfaction of the Obligations pro rata among the
Secured Parties (based on then-outstanding principal amounts of Debentures at
the time of any such determination), and to the payment of any other amounts
required by applicable law, after which the Secured Parties shall pay to the
applicable Debtor 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 Parties are legally entitled, the Debtors will be
liable for the deficiency, together with interest thereon, at the rate of 10%
per annum or the lesser amount permitted by applicable law (the "Default Rate"),

                                       15
<PAGE>

and the reasonable fees of any attorneys employed by the Secured Parties to
collect such deficiency. To the extent permitted by applicable law, each Debtor
waives all claims, damages and demands against the Secured Parties arising out
of the repossession, removal, retention or sale of the Collateral, unless due
solely to the gross negligence or willful misconduct of the Secured Parties as
determined by a final judgment (not subject to further appeal) of a court of
competent jurisdiction.

      10. Securities Law Provision. Each Debtor recognizes that the Agent may be
limited in its ability to effect a sale to the public of all or part of the
Pledged Securities by reason of certain prohibitions in the Securities Act of
1933, as amended, or other federal or state securities laws (collectively, the
"Securities Laws"), and may be compelled to resort to one or more sales to a
restricted group of purchasers who may be required to agree to acquire the
Pledged Securities for their own account, for investment and not with a view to
the distribution or resale thereof. Each Debtor agrees that sales so made may be
at prices and on terms less favorable than if the Pledged Securities were sold
to the public, and that the Agent has no obligation to delay the sale of any
Pledged Securities for the period of time necessary to register the Pledged
Securities for sale to the public under the Securities Laws. Each Debtor shall
cooperate with the Agent in its attempt to satisfy any requirements under the
Securities Laws (including, without limitation, registration thereunder if
requested by the Agent) applicable to the sale of the Pledged Securities by the
Agent.

      11. Costs and Expenses. Each Debtor agrees to pay all reasonable
out-of-pocket fees, costs and expenses incurred in connection with any filing
required hereunder, including without limitation, any financing statements
pursuant to the UCC, continuation statements, partial releases and/or
termination statements related thereto or any expenses of any searches
reasonably required by the Secured Parties. The Debtors shall also pay all other
claims and charges which in the reasonable opinion of the Secured Parties might
prejudice, imperil or otherwise affect the Collateral or the Security Interest
therein. The Debtors will also, upon demand, pay to the Secured Parties 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 Parties
may incur in connection with (i) the enforcement of this Security 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 Parties 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.

      12. Responsibility for Collateral. The Debtors assume all liabilities and
responsibility in connection with all Collateral, and the Obligations 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. Without
limiting the generality of the foregoing, (a) neither the Agent nor any Secured
Party (i) has any duty (either before or after an Event of Default) to collect
any amounts in respect of the Collateral or to preserve any rights relating to
the Collateral, or (ii) has any obligation to clean-up or otherwise prepare the
Collateral for sale, and (b) each Debtor shall remain obligated and liable under
each contract or agreement included in the Collateral to be observed or
performed by such Debtor thereunder. Neither the Agent nor any Secured Party
shall have any obligation or liability under any such contract or agreement by
reason of or arising out of this Security Agreement or the receipt by the Agent
or any Secured Party of any payment relating to any of the Collateral, nor shall

                                       16
<PAGE>

the Agent or any Secured Party be obligated in any manner to perform any of the
obligations of any Debtor under or pursuant to any such contract or agreement,
to make inquiry as to the nature or sufficiency of any payment received by the
Agent or any Secured Party in respect of the Collateral or as to the sufficiency
of any performance by any party under any such contract or agreement, to present
or file any claim, to take any action to enforce any performance or to collect
the payment of any amounts which may have been assigned to the Agent or to which
the Agent or any Secured Party may be entitled at any time or times.

      13. Security Interest Absolute. All rights of the Secured Parties and all
obligations of the Debtors hereunder, shall be absolute and unconditional,
irrespective of: (a) any lack of validity or enforceability of this Security
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 Parties 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 a
Debtor, 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 Parties shall continue even if the Obligations are barred
for any reason, including, without limitation, the running of the statute of
limitations or bankruptcy. Each Debtor 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 Parties 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 Parties,
then, in any such event, each Debtor's obligations hereunder shall survive
cancellation of this Security Agreement, and shall not be discharged or
satisfied by any prior payment thereof and/or cancellation of this Security
Agreement, but shall remain a valid and binding obligation enforceable in
accordance with the terms and provisions hereof. Each Debtor waives all right to
require the Secured Parties to proceed against any other person or entity or to
apply any Collateral which the Secured Parties may hold at any time, or to
marshal assets, or to pursue any other remedy. Each Debtor waives any defense
arising by reason of the application of the statute of limitations to any
obligation secured hereby.

      14. Term of Security Agreement. This Security Agreement and the Security
Interest shall terminate on the date on which all payments under the Debentures
have been indefeasibly paid in full and all other Obligations have been paid or
discharged; provided, however, that all indemnities of the Debtors contained in
this Security Agreement (including, without limitation, Annex B hereto) shall
survive and remain operative and in full force and effect regardless of the
termination of this Security Agreement.

                                       17
<PAGE>

      15. Power of Attorney; Further Assurances.

            (a) Each Debtor authorizes the Agent, and does hereby make,
constitute and appoint the Agent and their respective officers, agents,
successors or assigns with full power of substitution, as such Debtor's true and
lawful attorney-in-fact, with power, in the name of the various Secured Parties
or such Debtor, to, after the occurrence and during the continuance of an Event
of Default, (i) endorse any note, 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 Parties; (ii) to sign and endorse any financing statement
pursuant to the UCC 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; (v) to transfer any
Intellectual Property or provide licenses respecting any Intellectual Property;
and (vi) generally, at the option of the Secured Parties, and at the expense of
the Debtors, at any time, or from time to time, to execute and deliver any and
all documents and instruments and to do all acts and things which the Secured
Parties deem necessary to protect, preserve and realize upon the Collateral and
the Security Interest granted therein in order to effect the intent of this
Security Agreement and the Debentures all as fully and effectually as the
Debtors might or could do; and each Debtor 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 Security Agreement and thereafter as long as any of the Obligations shall
be outstanding. The designation set forth herein shall be deemed to amend and
supersede any inconsistent provision in the Organizational Documents or other
documents or agreements to which any Debtor is subject or to which any Debtor is
a party. Without limiting the generality of the foregoing, after the occurrence
and during the continuance of an Event of Default, each Secured Party is
specifically authorized to execute and file any applications for or instruments
of transfer and assignment of any patents, trademarks, copyrights or other
Intellectual Property with the United States Patent and Trademark Office and the
United States Copyright Office.

            (b) On a continuing basis, each Debtor will make, execute,
acknowledge, deliver, file and record, as the case may be, with the proper
filing and recording agencies in any jurisdiction, including, without
limitation, the jurisdictions indicated on Schedule C attached hereto, all such
instruments, and take all such action as may reasonably be deemed necessary or
advisable, or as reasonably requested by the Secured Parties, to perfect the
Security Interest granted hereunder and otherwise to carry out the intent and
purposes of this Security Agreement, or for assuring and confirming to the
Secured Parties the grant or perfection of a perfected security interest in all
the Collateral under the UCC.

            (c) Each Debtor hereby irrevocably appoints the Agent as such
Debtor's attorney-in-fact, with full authority in the place and instead of such
Debtor and in the name of such Debtor, from time to time in the Agent's
discretion, to take any action and to execute any instrument which the Secured
Parties may deem necessary or advisable to perfect the security interests
granted pursuant to the terms of this Security Agreement, including the filing,
in its sole discretion, of one or more financing or continuation statements and
amendments thereto, relative to any of the Collateral without the signature of

                                       18

such Debtor where permitted by law, which financing statements may (but need
not) describe the Collateral as "all assets" or "all personal property" or words
of like import, and ratifies all such actions taken by the Agent. This power of
attorney is coupled with an interest and shall be irrevocable for the term of
this Security Agreement and thereafter as long as any of the Obligations.

      16. Notices. All notices, requests, demands and other communications
hereunder shall be subject to the notice provision of the Purchase Agreement (as
such term is defined in the Debentures).

      17. 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 Parties 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 Parties'
rights and remedies hereunder.

      18. Appointment of the Agent. The Secured Parties hereby appoint Platinum
Long Term Growth III to act as their agent (the "Agent") for purposes of
exercising any and all rights and remedies of the Secured Parties hereunder.
Such appointment shall continue until revoked in writing by a Majority in
Interest, at which time a Majority in Interest shall appoint a new Agent;
provided, that the Agent may not be removed as agent unless the Agent and its
Affiliates shall then hold less than $25,000 principal amount of Debentures;
provided further that such removal may occur only if each of the other Secured
Parties shall then hold not less than $50,000 principal amount of Debentures.
The Agent shall have the rights, responsibilities and immunities set forth in
Annex B hereto.

Miscellaneous.

            (a) No course of dealing between the Debtors and the Secured
Parties, nor any failure to exercise, nor any delay in exercising, on the part
of the Secured Parties, 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 Parties 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 Security 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 Security Agreement, no provision of
this Security Agreement may be modified or amended except by a written agreement
specifically referring to this Security Agreement and signed by the parties
hereto.

            (d) In the event any provision of this Security Agreement is held to
be invalid, prohibited or unenforceable in any jurisdiction for any reason,
unless such provision is narrowed by judicial construction, this Security
Agreement shall, as to such jurisdiction, be construed as if such invalid,

                                       19
<PAGE>

prohibited or unenforceable provision had been more narrowly drawn so as not to
be invalid, prohibited or unenforceable. If, notwithstanding the foregoing, any
provision of this Security 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 Security Agreement and without affecting the
validity or enforceability of such provision or the other provisions of this
Security Agreement in any other jurisdiction.

            (e) No waiver of any breach or default or any right under this
Security 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 Security 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 Security Agreement.

            (h) All questions concerning the construction, validity, enforcement
and interpretation of this Security 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 Debtor agrees
that all proceedings concerning the interpretations, enforcement and defense of
the transactions contemplated by this Security Agreement and the Debentures
(whether brought against a party hereto or its respective affiliates, directors,
officers, shareholders, partners, members, employees or agents) shall be
commenced exclusively in the state and federal courts sitting in the City of New
York, Borough of Manhattan. Each Debtor 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, and hereby irrevocably waives, and agrees not to assert in any
proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such proceeding is improper. Each party hereto hereby
irrevocably waives personal service of process and consents to process being
served in any such 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 Security 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. Each party hereto
hereby irrevocably waives, to the fullest extent permitted by applicable law,
any and all right to trial by jury in any legal proceeding arising out of or
relating to this Security Agreement or the transactions contemplated hereby. If
any party shall commence a proceeding to enforce any provisions of this Security
Agreement, then the prevailing party in such proceeding shall be reimbursed by
the other party for its reasonable attorney's fees and other costs and expenses
incurred with the investigation, preparation and prosecution of such proceeding.

                                       20

            (i) This Security 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.

            (j) All Debtors shall jointly and severally be liable for the
obligations of each Debtor to the Secured Parties hereunder.

            (k) Each Debtor shall indemnify, reimburse and hold harmless the
Secured Parties and their respective partners, members, shareholders, officers,
directors, employees and agents (collectively, "Indemnitees") from and against
any and all losses, claims, liabilities, damages, penalties, suits, costs and
expenses, of any kind or nature, (including fees relating to the cost of
investigating and defending any of the foregoing) imposed on, incurred by or
asserted against such Indemnitee in any way related to or arising from or
alleged to arise from this Security Agreement or the Collateral, except any such
losses, claims, liabilities, damages, penalties, suits, costs and expenses which
result from the gross negligence or willful misconduct of the Indemnitee as
determined by a final, nonappealable decision of a court of competent
jurisdiction. This indemnification provision is in addition to, and not in
limitation of, any other indemnification provision in the Debentures, the
Purchase Agreement (as such term is defined in the Debentures) or any other
agreement, instrument or other document executed or delivered in connection
herewith or therewith.

            (l) Nothing in this Security Agreement shall be construed to subject
the Agent or any Secured Party to liability as a partner in any Debtor or any if
its direct or indirect subsidiaries that is a partnership or as a member in any
Debtor or any of its direct or indirect subsidiaries that is a limited liability
company, nor shall the Agent or any Secured Party be deemed to have assumed any
obligations under any partnership agreement or limited liability company
agreement, as applicable, of any such Debtor or any if its direct or indirect
subsidiaries or otherwise, unless and until any such Secured Party exercises its
right to be substituted for such Debtor as a partner or member, as applicable,
pursuant hereto.

            (m) To the extent that the grant of the security interest in the
Collateral and the enforcement of the terms hereof require the consent, approval
or action of any partner or member, as applicable, of any Debtor or any direct
or indirect subsidiary of any Debtor or compliance with any provisions of any of
the Organizational Documents, the Debtors hereby grant such consent and approval
and waive any such noncompliance with the terms of said documents.

      The undersigned hereby agrees that upon delivery of this Additional Debtor

                                       to

                               SECURITY AGREEMENT

                                    THE AGENT

      1. Appointment. The Secured Parties (all capitalized terms used herein and
not otherwise defined shall have the respective meanings provided in the
Security Agreement to which this Annex B is attached (the "Security
Agreement")), by their acceptance of the benefits of the Security Agreement,
hereby designate Platinum Long Term Growth III (the "Agent") as the Agent to act
as specified herein and in the Security Agreement. Each Secured Party shall be
deemed irrevocably to authorize the Agent to take such action on its behalf
under the provisions of the Security Agreement and any other Transaction
Document (as such term is defined in the Debentures) and to exercise such powers
and to perform such duties hereunder and thereunder as are specifically
delegated to or required of the Agent by the terms hereof and thereof and such
other powers as are reasonably incidental thereto. The Agent may perform any of
its duties hereunder by or through its agents or employees.

      2. Nature of Duties. The Agent shall have no duties or responsibilities
except those expressly set forth in the Security Agreement. Neither the Agent
nor any of its partners, members, shareholders, officers, directors, employees
or agents shall be liable for any action taken or omitted by it as such under
the Security Agreement or hereunder or in connection herewith or therewith, be
responsible for the consequence of any oversight or error of judgment or
answerable for any loss, unless caused solely by its or their gross negligence
or willful conduct as determined by a final judgment (not subject to further
appeal) of a court of competent jurisdiction. The duties of the Agent shall be
mechanical and administrative in nature; the Agent shall not have by reason of
the Security Agreement or any other Transaction Document a fiduciary
relationship in respect of any Debtor or any Secured Party; and nothing in the
Security Agreement or any other Transaction Document, expressed or implied, is
intended to or shall be so construed as to impose upon the Agent any obligations
in respect of the Security Agreement or any other Transaction Document except as
expressly set forth herein and therein.

      3. Lack of Reliance on the Agent. Independently and without reliance upon
the Agent, each Secured Party, to the extent it deems appropriate, has made and
shall continue to make (i) its own independent investigation of the financial
condition and affairs of the Company and its subsidiaries in connection with
such Secured Party's investment in the Debtors, the creation and continuance of
the Obligations, the transactions contemplated by the Transaction Documents, and
the taking or not taking of any action in connection therewith, and (ii) its own
appraisal of the creditworthiness of the Company and its subsidiaries, and of
the value of the Collateral from time to time, and the Agent shall have no duty
or responsibility, either initially or on a continuing basis, to provide any
Secured Party with any credit, market or other information with respect thereto,
whether coming into its possession before any Obligations are incurred or at any
time or times thereafter. The Agent shall not be responsible to the Debtors or

                                       36
<PAGE>

any Secured Party for any recitals, statements, information, representations or
warranties herein or in any document, certificate or other writing delivered in
connection herewith, or for the execution, effectiveness, genuineness, validity,
enforceability, perfection, collectibility, priority or sufficiency of the
Security Agreement or any other Transaction Document, or for the financial
condition of the Debtors or the value of any of the Collateral, or be required
to make any inquiry concerning either the performance or observance of any of
the terms, provisions or conditions of the Security Agreement or any other
Transaction Document, or the financial condition of the Debtors, or the value of
any of the Collateral, or the existence or possible existence of any default or
Event of Default under the Security Agreement, the Debentures or any of the
other Transaction Documents.

      4. Certain Rights of the Agent. The Agent shall have the right to take any
action with respect to the Collateral, on behalf of all of the Secured Parties.
To the extent practical, the Agent shall request instructions from the Secured
Parties with respect to any material act or action (including failure to act) in
connection with the Security Agreement or any other Transaction Document, and
shall be entitled to act or refrain from acting in accordance with the
instructions of Secured Parties holding a majority in principal amount of
Debentures (based on then-outstanding principal amounts of Debentures at the
time of any such determination); if such instructions are not provided despite
the Agent's request therefor, the Agent shall be entitled to refrain from such
act or taking such action, and if such action is taken, shall be entitled to
appropriate indemnification from the Secured Parties in respect of actions to be
taken by the Agent; and the Agent shall not incur liability to any person or
entity by reason of so refraining. Without limiting the foregoing, (a) no
Secured Party shall have any right of action whatsoever against the Agent as a
result of the Agent acting or refraining from acting hereunder in accordance
with the terms of the Security Agreement or any other Transaction Document, and
the Debtors shall have no right to question or challenge the authority of, or
the instructions given to, the Agent pursuant to the foregoing and (b) the Agent
shall not be required to take any action which the Agent believes (i) could
reasonably be expected to expose it to personal liability or (ii) is contrary to
this Security Agreement, the Transaction Documents or applicable law.

      5. Reliance. The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, statement,
certificate, telex, teletype or telecopier message, cablegram, radiogram, order
or other document or telephone message signed, sent or made by the proper person
or entity, and, with respect to all legal matters pertaining to the Security
Agreement and the other Transaction Documents and its duties thereunder, upon
advice of counsel selected by it and upon all other matters pertaining to this
Security Agreement and the other Transaction Documents and its duties
thereunder, upon advice of other experts selected by it.

      6. Indemnification. To the extent that the Agent is not reimbursed and
indemnified by the Debtors, the Secured Parties will, jointly and severally,
reimburse and indemnify the Agent, in proportion to their initially purchased
respective principal amounts of Debentures, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in performing its duties
hereunder or under the Security Agreement or any other Transaction Document, or
in any way relating to or arising out of the Security Agreement or any other
Transaction Document except for those determined by a final judgment (not

                                       37
<PAGE>

subject to further appeal) of a court of competent jurisdiction to have resulted
solely from the Agent's own gross negligence or willful misconduct. Prior to
taking any action hereunder as agent, the Agent may require each Secured Party
to deposit with it sufficient sums as it determines in good faith is necessary
to protect the Agent for costs and expenses associated with taking such action.

      7. Resignation by the Agent.

            (a) The Agent may resign from the performance of all its functions
and duties under the Security Agreement and the other Transaction Documents at
any time by giving thirty (30) days' prior written notice (as provided in the
Security Agreement) to the Debtors and the Secured Parties. Such resignation
shall take effect upon the appointment of a successor Agent pursuant to clauses
(b) and (c) below.

            (b) Upon any such notice of resignation, the Secured Parties, acting
by a Majority in Interest, shall appoint a successor agent hereunder.

            (c) If a successor agent shall not have been so appointed within
said 30-day period, the Agent shall then appoint a successor agent who shall
serve as the Agent until such time, if any, as the Secured Parties appoint a
successor agent as provided above. If a successor agent has not been appointed
within such 30-day period, the Agent may petition any court of competent
jurisdiction or may interplead the Debtors and the Secured Parties in a
proceeding for the appointment of a successor agent, and all fees, including,
but not limited to, extraordinary fees associated with the filing of
interpleader and expenses associated therewith, shall be payable by the Debtors
on demand.

      8. Rights with respect to Collateral. Each Secured Party agrees with all
other Secured Parties and the Agent (i) that it shall not, and shall not attempt
to, exercise any rights with respect to its security interest in the Collateral,
whether pursuant to any other agreement or otherwise (other than pursuant to
this Security Agreement), or take or institute any action against the Agent or
any of the other Secured Parties in respect of the Collateral or its rights
hereunder (other than any such action arising from the breach of this Security
Agreement) and (ii) that such Secured Party has no other rights with respect to
the Collateral other than as set forth in this Security Agreement and the other
Transaction Documents.

transactions contemplated thereby, each Guarantor hereby agrees with the
Purchasers as follows:

<PAGE>

                  (i) The Guarantors hereby, jointly and severally,
                  unconditionally and irrevocably, guarantee to the Purchasers
                  and their respective successors, endorsees, transferees and
                  assigns, the prompt and complete payment and performance by
                  the Company when due (whether at the stated maturity, by
                  acceleration or otherwise) of the Obligations.

                  (ii) Anything herein or in any other Transaction Document to
                  the contrary notwithstanding, the maximum liability of each
                  Guarantor hereunder and under the other Transaction Documents
                  shall in no event exceed the amount which can be guaranteed by
                  such Guarantor under applicable federal and state laws,
                  including laws relating to the insolvency of debtors,
                  fraudulent conveyance or transfer or laws affecting the rights
                  of creditors generally (after giving effect to the right of
                  contribution established in Section 2(b)).

                  (iii) Each Guarantor agrees that the Obligations may at any
                  time and from time to time exceed the amount of the liability
                  of such Guarantor hereunder without impairing the guarantee
                  contained in this Section 2 or affecting the rights and
                  remedies of the Purchasers hereunder.

                  (iv) The guarantee contained in this Section 2 shall remain in
                  full force and effect until all the Obligations and the
                  obligations of each Guarantor under the guarantee contained in
                  this Section 2 shall have been satisfied by payment in full.

                  (v) No payment made by the Company, any of the Guarantors, any
                  other guarantor or any other Person or received or collected
                  by the Purchasers from the Company, any of the Guarantors, any
                  other guarantor or any other Person by virtue of any action or
                  proceeding or any set-off or appropriation or application at
                  any time or from time to time in reduction of or in payment of
                  the Obligations shall be deemed to modify, reduce, release or
                  otherwise affect the liability of any Guarantor hereunder
                  which shall, notwithstanding any such payment (other than any
                  payment made by such Guarantor in respect of the Obligations
                  or any payment received or collected from such Guarantor in
                  respect of the Obligations), remain liable for the Obligations
                  up to the maximum liability of such Guarantor hereunder until
                  the Obligations are paid in full.

                  (vi) Notwithstanding anything to the contrary in this
                  Agreement, with respect to any defaulted non-monetary
                  Obligations the specific performance of which by the
                  Guarantors is not reasonably possible (e.g. the issuance of
                  the Company's Common Stock), the Guarantors shall only be
                  liable for making the Purchasers whole on a monetary basis for
                  the Company's failure to perform such Obligations in
                  accordance with the Transaction Documents.

                                       2

            (b) Right of Contribution. Each Guarantor hereby agrees that to the
extent that a Guarantor shall have paid more than its proportionate share of any
payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder which has not paid
its proportionate share of such payment. Each Guarantor's right of contribution
shall be subject to the terms and conditions of Section 2(c). The provisions of
this Section 2(b) shall in no respect limit the obligations and liabilities of
any Guarantor to the Purchasers, and each Guarantor shall remain liable to the
Purchasers for the full amount guaranteed by such Guarantor hereunder.

            (c) No Subrogation. Notwithstanding any payment made by any
Guarantor hereunder or any set-off or application of funds of any Guarantor by
the Purchasers, no Guarantor shall be entitled to be subrogated to any of the
rights of the Purchasers against the Company or any other Guarantor or any
collateral security or guarantee or right of offset held by the Purchasers for
the payment of the Obligations, nor shall any Guarantor seek or be entitled to
seek any contribution or reimbursement from the Company or any other Guarantor
in respect of payments made by such Guarantor hereunder, until all amounts owing
to the Purchasers by the Company on account of the Obligations are paid in full.
If any amount shall be paid to any Guarantor on account of such subrogation
rights at any time when all of the Obligations shall not have been paid in full,
such amount shall be held by such Guarantor in trust for the Purchasers,
segregated from other funds of such Guarantor, and shall, forthwith upon receipt
by such Guarantor, be turned over to the Purchasers in the exact form received
by such Guarantor (duly indorsed by such Guarantor to the Purchasers, if
required), to be applied against the Obligations, whether matured or unmatured,
in such order as the Purchasers may determine.

            (d) Amendments, Etc. With Respect to the Obligations. Each Guarantor
shall remain obligated hereunder notwithstanding that, without any reservation
of rights against any Guarantor and without notice to or further assent by any
Guarantor, any demand for payment of any of the Obligations made by the
Purchasers may be rescinded by the Purchasers and any of the Obligations
continued, and the Obligations, or the liability of any other Person upon or for
any part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Purchasers, and the Purchase Agreement and the
other Transaction Documents and any other documents executed and delivered in
connection therewith may be amended, modified, supplemented or terminated, in
whole or in part, as the Purchasers may deem advisable from time to time, and
any collateral security, guarantee or right of offset at any time held by the
Purchasers for the payment of the Obligations may be sold, exchanged, waived,
surrendered or released. The Purchasers shall have no obligation to protect,
secure, perfect or insure any Lien at any time held by them as security for the
Obligations or for the guarantee contained in this Section 2 or any property
subject thereto.

            (e) Guarantee Absolute and Unconditional. Each Guarantor waives any
and all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Purchasers upon the
guarantee contained in this Section 2 or acceptance of the guarantee contained
in this Section 2; the Obligations, and any of them, shall conclusively be
deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon the guarantee contained in this Section 2;
and all dealings between the Company and any of the Guarantors, on the one hand,
and the Purchasers, on the other hand, likewise shall be conclusively presumed
to have been had or consummated in reliance upon the guarantee contained in this
Section 2. Each Guarantor waives to the extent permitted by law diligence,

                                       3
<PAGE>

presentment, protest, demand for payment and notice of default or nonpayment to
or upon the Company or any of the Guarantors with respect to the Obligations.
Each Guarantor understands and agrees that the guarantee contained in this
Section 2 shall be construed as a continuing, absolute and unconditional
guarantee of payment without regard to (a) the validity or enforceability of the
Purchase Agreement or any other Transaction Document, any of the Obligations or
any other collateral security therefor or guarantee or right of offset with
respect thereto at any time or from time to time held by the Purchasers, (b) any
defense, set-off or counterclaim (other than a defense of payment or performance
or fraud or misconduct by Purchasers) which may at any time be available to or
be asserted by the Company or any other Person against the Purchasers, or (c)
any other circumstance whatsoever (with or without notice to or knowledge of the
Company or such Guarantor) which constitutes, or might be construed to
constitute, an equitable or legal discharge of the Company for the Obligations,
or of such Guarantor under the guarantee contained in this Section 2, in
bankruptcy or in any other instance. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against any Guarantor, the
Purchasers may, but shall be under no obligation to, make a similar demand on or
otherwise pursue such rights and remedies as they may have against the Company,
any other Guarantor or any other Person or against any collateral security or
guarantee for the Obligations or any right of offset with respect thereto, and
any failure by the Purchasers to make any such demand, to pursue such other
rights or remedies or to collect any payments from the Company, any other
Guarantor or any other Person or to realize upon any such collateral security or
guarantee or to exercise any such right of offset, or any release of the
Company, any other Guarantor or any other Person or any such collateral
security, guarantee or right of offset, shall not relieve any Guarantor of any
obligation or liability hereunder, and shall not impair or affect the rights and
remedies, whether express, implied or available as a matter of law, of the
Purchasers against any Guarantor. For the purposes hereof, "demand" shall
include the commencement and continuance of any legal proceedings.

            (f) Reinstatement. The guarantee contained in this Section 2 shall
continue to be effective, or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any of the Obligations is rescinded or must
otherwise be restored or returned by the Purchasers upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Company or any
Guarantor, or upon or as a result of the appointment of a receiver, intervenor
or conservator of, or trustee or similar officer for, the Company or any
Guarantor or any substantial part of its property, or otherwise, all as though
such payments had not been made.

            (g) Payments. Each Guarantor hereby guarantees that payments
hereunder will be paid to the Purchasers without set-off or counterclaim in U.S.
dollars at the address set forth or referred to in the Purchase Agreement.

      3. Representations and Warranties. Each Guarantor hereby makes the
following representations and warranties to Purchasers as of the date hereof:

            (a) Organization and Qualification. The Guarantor is a corporation,
duly incorporated, validly existing and in good standing under the laws of the
applicable jurisdiction set forth on Schedule 1, with the requisite corporate
power and authority to own and use its properties and assets and to carry on its

                                       4
<PAGE>

business as currently conducted. The Guarantor has no subsidiaries other than
those identified as such on the Disclosure Schedules to the Purchase Agreement.
The Guarantor is duly qualified to do business and is in good standing as a
foreign corporation in each jurisdiction in which the nature of the business
conducted or property owned by it makes such qualification necessary, except
where the failure to be so qualified or in good standing, as the case may be,
could not, individually or in the aggregate, (x) adversely affect the legality,
validity or enforceability of any of this Guaranty in any material respect, (y)
have a material adverse effect on the results of operations, assets, prospects,
or financial condition of the Guarantor or (z) adversely impair in any material
respect the Guarantor's ability to perform fully on a timely basis its
obligations under this Guaranty (a "Material Adverse Effect").

            (b) Authorization; Enforcement. The Guarantor has the requisite
corporate power and authority to enter into and to consummate the transactions
contemplated by this Guaranty, and otherwise to carry out its obligations
hereunder. The execution and delivery of this Guaranty by the Guarantor and the
consummation by it of the transactions contemplated hereby have been duly
authorized by all requisite corporate action on the part of the Guarantor. This
Guaranty has been duly executed and delivered by the Guarantor and constitutes
the valid and binding obligation of the Guarantor enforceable against the
Guarantor in accordance with its terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium,
liquidation or similar laws relating to, or affecting generally the enforcement
of, creditors' rights and remedies or by other equitable principles of general
application.

            (c) No Conflicts. The execution, delivery and performance of this
Guaranty by the Guarantor and the consummation by the Guarantor of the
transactions contemplated thereby do not and will not (i) conflict with or
violate any provision of its Certificate of Incorporation or By-laws or (ii)
conflict with, constitute a default (or an event which with notice or lapse of
time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any agreement,
indenture or instrument to which the Guarantor is a party, or (iii) result in a
violation of any law, rule, regulation, order, judgment, injunction, decree or
other restriction of any court or governmental authority to which the Guarantor
is subject (including Federal and state securities laws and regulations), or by
which any material property or asset of the Guarantor is bound or affected,
except in the case of each of clauses (ii) and (iii), such conflicts, defaults,
terminations, amendments, accelerations, cancellations and violations as could
not, individually or in the aggregate, have or result in a Material Adverse
Effect. The business of the Guarantor is not being conducted in violation of any
law, ordinance or regulation of any governmental authority, except for
violations which, individually or in the aggregate, do not have a Material
Adverse Effect.

            (d) Consents and Approvals. The Guarantor is not required to obtain
any consent, waiver, authorization or order of, or make any filing or
registration with, any court or other federal, state, local, foreign or other
governmental authority or other person in connection with the execution,
delivery and performance by the Guarantor of this Guaranty.

            (e) Purchase Agreement. The representations and warranties of the
Company set forth in the Purchase Agreement as they relate to such Guarantor,
each of which is hereby incorporated herein by reference, are true and correct

                                       5
<PAGE>

as of each time such representations are deemed to be made pursuant to such
Purchase Agreement, and the Purchasers shall be entitled to rely on each of them
as if they were fully set forth herein, provided, that each reference in each
such representation and warranty to the Company's knowledge shall, for the
purposes of this Section 3, be deemed to be a reference to such Guarantor's
knowledge.

            (f) Foreign Law. Each Guarantor has consulted with appropriate
foreign legal counsel with respect to any of the above representations for which
non-U.S. law is applicable. Such foreign counsel have advised each applicable
Guarantor that such counsel knows of no reason why any of the above
representations would not be true and accurate. Such foreign counsel were
provided with copies of this Subsidiary Guarantee and the Transaction Documents
prior to rendering their advice.

      4. Covenants.

            (a) Each Guarantor covenants and agrees with the Purchasers that,
from and after the date of this Guarantee until the Obligations shall have been
paid in full, such Guarantor shall take, and/or shall refrain from taking, as
the case may be, each commercially reasonable action that is necessary to be
taken or not taken, as the case may be, so that no Event of Default is caused by
the failure to take such action or to refrain from taking such action by such
Guarantor.

            (b) So long as any of the Obligations are outstanding, each
Guarantor will not directly or indirectly on or after the date of this
Guarantee:

                  (i) except with the prior written consent of the Agent (as
                  defined in the Security Agreement), enter into, create, incur,
                  assume or suffer to exist any indebtedness for borrowed money
                  of any kind, including but not limited to, a guarantee, on or
                  with respect to any of its property or assets now owned or
                  hereafter acquired or any interest therein or any income or
                  profits therefrom that is senior to, or pari passu with, in
                  any respect, such Guarantor's obligations hereunder;

                  (ii) enter into, create, incur, assume or suffer to exist any
                  liens of any kind, on or with respect to any of its property
                  or assets now owned or hereafter acquired or any interest
                  therein or any income or profits therefrom that is senior to,
                  in any respect, such Guarantor's obligations hereunder;

                  (iii) amend its certificate of incorporation, bylaws or other
                  charter documents so as to adversely affect any rights of the
                  Holder hereunder;

                  (iv) repay, repurchase or offer to repay, repurchase or
                  otherwise acquire more than a de minimis number of shares of
                  its Common Stock or Common Stock Equivalents;

                  (v) enter into any agreement with respect to any of the
                  foregoing; or

                                       6
<PAGE>

                  (vi) pay cash dividends on any equity securities of the
                  Company.

      5. Miscellaneous.

            (a) Amendments in Writing. None of the terms or provisions of this
Guarantee may be waived, amended, supplemented or otherwise modified except in
writing by the Purchasers.

            (b) Notices. All notices, requests and demands to or upon the
Purchasers or any Guarantor hereunder shall be effected in the manner provided
for in the Purchase Agreement; provided that any such notice, request or demand
to or upon any Guarantor shall be addressed to such Guarantor at its notice
address set forth on Schedule 5(b).

            (c) No Waiver By Course Of Conduct; Cumulative Remedies. The
Purchasers shall not by any act (except by a written instrument pursuant to
Section 5(a)), delay, indulgence, omission or otherwise be deemed to have waived
any right or remedy hereunder or to have acquiesced in any default under the
Transaction Documents or Event of Default. No failure to exercise, nor any delay
in exercising, on the part of the Purchasers, any right, power or privilege
hereunder shall operate as a waiver thereof. No single or partial exercise of
any right, power or privilege hereunder shall preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. A
waiver by the Purchasers of any right or remedy hereunder on any one occasion
shall not be construed as a bar to any right or remedy which the Purchasers
would otherwise have on any future occasion. The rights and remedies herein
provided are cumulative, may be exercised singly or concurrently and are not
exclusive of any other rights or remedies provided by law.

            (d) Enforcement Expenses; Indemnification.

                  (i) Each Guarantor agrees to pay, or reimburse the Purchasers
                  for, all its costs and expenses incurred in collecting against
                  such Guarantor under the guarantee contained in Section 2 or
                  otherwise enforcing or preserving any rights under this
                  Guarantee and the other Transaction Documents to which such
                  Guarantor is a party, including, without limitation, the
                  reasonable fees and disbursements of counsel to the
                  Purchasers.

                  (ii) Each Guarantor agrees to pay, and to save the Purchasers
                  harmless from, any and all liabilities with respect to, or
                  resulting from any delay in paying, any and all stamp, excise,
                  sales or other taxes which may be payable or determined to be
                  payable in connection with any of the transactions
                  contemplated by this Guarantee.

                  (iii) Each Guarantor agrees to pay, and to save the Purchasers
                  harmless from, any and all liabilities, obligations, losses,

                  or disbursements of any kind or nature whatsoever with respect
                  to the execution, delivery, enforcement, performance and
                  administration of this Guarantee to the extent the Company

                  (iv) The agreements in this Section shall survive repayment of
                  the Obligations and all other amounts payable under the
                  Purchase Agreement and the other Transaction Documents.

            (e) Successor and Assigns. This Guarantee shall be binding upon the
successors and assigns of each Guarantor and shall inure to the benefit of the
Purchasers and their respective successors and assigns; provided that no
Guarantor may assign, transfer or delegate any of its rights or obligations
under this Guarantee without the prior written consent of the Purchasers.

            (f) Set-Off. Each Guarantor hereby irrevocably authorizes the
Purchasers at any time and from time to time while an Event of Default under any
of the Transaction Documents shall have occurred and be continuing, without
notice to such Guarantor or any other Guarantor, any such notice being expressly
waived by each Guarantor, to set-off and appropriate and apply any and all
deposits, credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by the Purchasers to or for the credit or the account of such
Guarantor, or any part thereof in such amounts as the Purchasers may elect,
against and on account of the obligations and liabilities of such Guarantor to
the Purchasers hereunder and claims of every nature and description of the
Purchasers against such Guarantor, in any currency, whether arising hereunder,
under the Purchase Agreement, any other Transaction Document or otherwise, as
the Purchasers may elect, whether or not the Purchasers have made any demand for
payment and although such obligations, liabilities and claims may be contingent
or unmatured. The Purchasers shall notify such Guarantor promptly of any such
set-off and the application made by the Purchasers of the proceeds thereof,
provided that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of the Purchasers under this Section
are in addition to other rights and remedies(including, without limitation,
other rights of set-off) which the Purchasers may have.

            (g) Counterparts. This Guarantee may be executed by one or more of
the parties to this Guarantee on any number of separate counterparts (including
by telecopy), and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

            (h) Severability. Any provision of this Guarantee which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

            (i) Section Headings. The Section headings used in this Guarantee
are for convenience of reference only and are not to affect the construction
hereof or be taken into consideration in the interpretation hereof.

            (j) Integration. This Guarantee and the other Transaction Documents
represent the agreement of the Guarantors and the Purchasers with respect to the
subject matter hereof and thereof, and there are no promises, undertakings,
representations or warranties by the Purchasers relative to subject matter
hereof and thereof not expressly set forth or referred to herein or in the other
Transaction Documents.

                  pursuant thereto;

                  (iv) agrees that nothing herein shall affect the right to
