irrevocably authorizes the Secured Party at any time and from time to time to
file in any Uniform Commercial Code jurisdiction any initial financing
statements and amendments thereto that, (a) describe the Collateral (i) as all

other information required by part 5 of Article 9 of the Uniform Commercial Code

agrees to furnish any such information to the Secured Party promptly upon

filed in any Uniform Commercial Code jurisdiction any like initial financing
statements or amendments thereto if filed prior to the date hereof.

            4.    OTHER ACTIONS. Further to insure the attachment, perfection

Secured Party's security interest in the Collateral, Debtor agrees, in each case
at Debtor's own expense, to take the following actions with respect to the
following Collateral:

                  4.1   PROMISSORY NOTES AND TANGIBLE CHATTEL PAPER. If Debtor
shall at any time hold or acquire any promissory notes or tangible chattel
paper, Debtor shall forthwith endorse, assign and deliver the same to the
Secured Party, accompanied by such instruments of transfer or assignment duly
executed in blank as the Secured Party may from time to time specify.

                  4.2   DEPOSIT ACCOUNTS. For each deposit account that Debtor
at any time opens or maintains, Debtor shall, at the Secured Party's request and
option, pursuant to an



                                      -2-
<PAGE>

agreement in form and substance satisfactory to the Secured Party, either (a)
cause the depositary bank to agree to comply at any time with instructions from
the Secured Party to such depositary bank directing the disposition of funds
from time to time credited to such deposit account, without further consent of
Debtor, or (b) arrange for the Secured Party to become the customer of the
depositary bank with respect to the deposit account, with Debtor being
permitted, only with the consent of the Secured Party, to exercise rights to
withdraw funds from such deposit account. The Secured Party agrees with Debtor
that the Secured Party shall not give any such instructions or withhold any
withdrawal rights from Debtor, unless an Event of Default has occurred and is
continuing. The provisions of this paragraph shall not apply to (i) any deposit
account for which Debtor, the depositary bank and the Secured Party have entered
into a cash collateral agreement specially negotiated among Debtor, the
depositary bank and the Secured Party for the specific purpose set forth
therein, (ii) any fiduciary deposit accounts, (iii) deposit accounts for which
the Secured Party is the depositary and (iv) deposit accounts specially and
exclusively used for payroll, payroll taxes and other employee wage and benefit
payments to or for the benefit of Debtor's salaried employees.

                  4.3   INVESTMENT PROPERTY. If Debtor shall at any time hold or
acquire any certificated securities, Debtor shall forthwith endorse, assign and
deliver the same to the Secured Party, accompanied by such instruments of
transfer or assignment duly executed in blank as the Secured Party may from time
to time specify. If any securities now or hereafter acquired by Debtor are
uncertificated and are issued to Debtor or its nominee directly by the issuer
thereof, Debtor shall immediately notify the Secured Party thereof and, at the
Secured Party's request and option, pursuant to an agreement in form and
substance satisfactory to the Secured Party, either (a) cause the issuer to
agree to comply with instructions from the Secured Party as to such securities,
without further consent of Debtor or such nominee, or (b) arrange for the
Secured Party to become the registered owner of the securities. If any
securities, whether certificated or uncertificated, or other investment property
now or hereafter acquired by Debtor are held by Debtor or its nominee through a
securities intermediary or commodity intermediary, Debtor shall immediately
notify the Secured Party thereof and, at the Secured Party's request and option,
pursuant to an agreement in form and substance satisfactory to the Secured
Party, either (i) cause such securities intermediary or (as the case may be)
commodity intermediary to agree to comply with entitlement orders or other
instructions from the Secured Party to such securities intermediary as to such
securities or other investment property, or (as the case may be) to apply any
value distributed on account of any commodity contract as directed by the
Secured Party to such commodity intermediary, in each case without further
consent of Debtor or such nominee, or (ii) in the case of financial assets or
other investment property held through a securities intermediary, arrange for
the Secured Party to become the entitlement holder with respect to such
investment property, with Debtor being permitted, only with the consent of the
Secured Party, to exercise rights to withdraw or otherwise deal with such
investment property. The Secured Party agrees with Debtor that the Secured Party
shall not give any such entitlement orders or instructions or directions to any
such issuer, securities intermediary or commodity intermediary, and shall not
withhold its consent to the exercise of any withdrawal or dealing rights by
Debtor, unless an Event of Default has occurred and is continuing. The
provisions of this paragraph shall not apply to any financial assets credited to
a securities account for which the Secured Party is the securities intermediary.

                  4.4   COLLATERAL IN THE POSSESSION OF A BAILEE. If any goods
are at any time in the possession of a bailee, Debtor shall promptly notify the
Secured Party thereof and, if requested by the Secured Party, shall promptly
obtain an acknowledgment from the bailee, in form and substance satisfactory to
the Secured Party, that the bailee holds such Collateral for the benefit of the
Secured Party and shall act upon the instructions of the Secured Party, without
the further consent of Debtor. The Secured Party agrees with Debtor that the
Secured Party shall not give any such instructions unless an Event of Default
has occurred and is continuing,

                  4.5   ELECTRONIC CHATTEL PAPER AND TRANSFERABLE RECORDS. If
Debtor at any time holds or acquires an interest in any electronic chattel paper
or any "transferable record," as that term is defined in Section 201 of the
federal Electronic Signatures in Global and National Commerce Act, or in Section
16 of the Uniform Electronic Transactions Act as in effect in any relevant
jurisdiction, Debtor shall promptly notify the Secured Party thereof and, at the
request of the Secured Party, shall take such action as the Secured Party may
reasonably request to vest in the Secured Party control, under Section 9-105 of
the Uniform Commercial Code, of such electronic chattel paper or control under
Section 201 of the federal Electronic Signatures in Global and National Commerce
Act or, as the case may be, Section 16 of the Uniform Electronic Transactions
Act, as so in effect in such jurisdiction, of such transferable record. The
Secured Party agrees with Debtor that the Secured Party will arrange, pursuant
to procedures satisfactory to the Secured Party and so long as such procedures
will not result in the Secured Party's loss of control, for Debtor to make
alterations to the electronic chattel paper or transferable record permitted
under Section 9-105 of the Uniform Commercial Code or, as the case may be,
Section 201 of the federal Electronic Signatures in Global and National Commerce
Act or Section 16 of the Uniform Electronic Transactions Act for a party in
control to make without loss of control, unless an Event of Default has occurred
and is continuing or would occur after taking into account any action by Debtor
with respect to such electronic chattel paper or transferable record.

                  4.6   LETTER OF CREDIT RIGHTS. If Debtor is at any time a
beneficiary under a letter of credit now or hereafter issued, Debtor shall
promptly notify the Secured Party thereof and, at the request and option of the
Secured Party, Debtor shall, pursuant to an agreement in form and substance
satisfactory to the Secured Party, either (i) arrange for the issuer and any
confirmer of such letter of credit to consent to an assignment to the Secured
Party of the proceeds of any drawing under the letter of credit or (ii) arrange
for the Secured Party to become the transferee beneficiary of the letter of
credit, with the Secured Party agreeing, in each case, that the proceeds of any
drawing under the letter of credit are applied as provided in the Notes.

                  4.7   COMMERCIAL TORT CLAIMS. If Debtor shall at any time hold
or acquire a commercial tort claim, Debtor shall immediately notify the Secured
Party in a writing signed by Debtor of the brief details thereof and grant to
the Secured Party in such writing a security interest therein and in the
proceeds thereof, all upon the terms of this Agreement, with such writing to be
in form and substance satisfactory to the Secured Party.

                  4.8   OTHER ACTIONS AS TO ANY AND ALL COLLATERAL. Debtor
further agrees to take any other action reasonably requested by the Secured
Party to insure the attachment,



                                      -4-

perfection and first priority of, and the ability of the Secured Party to
enforce, the Secured Party's security interest in any and all of the Collateral
including, without limitation, (a) executing, delivering and, where appropriate,
filing financing statements and amendments relating thereto under the Uniform
Commercial Code, to the extent, if any, that Debtor's signature thereon is
required therefor, (b) causing the Secured Party's name to be noted as secured
party on any certificate of title for a titled good if such notation is a
condition to attachment, perfection or priority of, or ability of the Secured
Party to enforce, the Secured Party's security interest in such Collateral, (c)
complying with any provision of any statute, regulation or treaty of the United
States as to any Collateral if compliance with such provision is a condition to

enforce, the Secured Party's security interest in such Collateral, (d) obtaining
governmental and other third party consents and approvals, including without
limitation any consent of any licensor, lessor or other person obligated on
Collateral, (e) obtaining waivers from mortgagees and landlords in form and
substance satisfactory to the Secured Party and (f) taking all actions required
by any earlier versions of the Uniform Commercial Code or by other law, as
applicable in any relevant Uniform Commercial Code jurisdiction, or by other law
as applicable in any foreign jurisdiction.

            5.    RELATION TO OTHER SECURITY DOCUMENTS. The provisions of this
Agreement supplement the provisions of any real estate mortgage, deed of trust
or deed of hypothec granted by Debtor to the Secured Party and securing the
payment or performance of any of the Obligations. Nothing contained in any such
real estate mortgage, deed of trust or deed of hypothec shall derogate from any
of the rights or remedies of the Secured Party hereunder.

financially sound and reputable insurers insurance with respect to its
properties and business against such casualties and contingencies as shall be in
accordance with general practices of businesses engaged in similar activities in
similar geographic areas. Such insurance shall be in such


                                      -6-
<PAGE>

minimum amounts that Debtor will not, be deemed a co-insurer under applicable
insurance laws, regulations and policies and otherwise shall be in such amounts,
contain such terms, be in such forms and be for such periods as may be
reasonably satisfactory to the Secured Party. In addition, all such insurance
shall be payable to the Secured Party as loss payee under a standard loss payee
clause. Without limiting the foregoing, Debtor will (i) keep all of its physical
property insured with casualty or physical hazard insurance on an "all risks"

amount" clause in an amount equal to 100% of the full replacement cost of such
property, (ii) maintain all such workers' compensation or similar insurance as

to those generally maintained by businesses engaged in similar activities in
similar geographic areas, general public liability insurance against claims of
bodily injury, death or property damage occurring, on, in or about the
properties of Debtor; business interruption insurance; and product liability
insurance.

            10.2  INSURANCE PROCEEDS. The proceeds of any casualty insurance in
respect of any casualty loss of any of the Collateral shall, subject to the
rights, if any, of other parties with a prior interest in the property covered
thereby, (i) so long as no Event of Default has occurred and is continuing, be
disbursed to Debtor for direct application by Debtor solely to the repair or
replacement of Debtor's property so damaged or destroyed, but only to the extent
of the replacement cost of such property and (ii) in all other circumstances
(including any excess from clause (i) of this Section 10.2), be held by the
Secured Party as cash collateral for the Obligations. The Secured Party may, at
its sole option, disburse from time to time all or any part of such proceeds so
held as cash collateral, upon such terms and conditions, as the Secured Party
may reasonably prescribe, for direct application by Debtor solely to the repair
or replacement of Debtor's property so damaged or destroyed, or the Secured
Party may apply all or any part of such proceeds to the Obligations.

            10.3  NOTICE OF CANCELLATION, ETC. All policies of insurance shall

Secured Party with certificates of insurance and policies evidencing compliance
with the foregoing insurance provision.

      11.   COLLATERAL PROTECTION EXPENSES: PRESERVATION OF COLLATERAL.

            11.1  EXPENSES INCURRED BY SECURED PARTY. In its discretion, the
Secured Party may discharge taxes and other encumbrances at any time levied or
placed on any of the Collateral, make repairs thereto and pay any necessary
filing fees or, if the debtor fails to do so, insurance premiums. Debtor agrees
to reimburse the Secured Party on demand for any and all expenditures so made.
The Secured Party shall have no obligation to Debtor to make any such
expenditures, nor shall the making thereof relieve Debtor of any default.

            11.2  SECURED PARTY'S OBLIGATIONS AND DUTIES. Anything herein to the
contrary notwithstanding, Debtor shall remain liable under each contract or
agreement comprised



                                      -7-
<PAGE>

in the Collateral to be observed or performed by Debtor thereunder. The Secured
Party shall not have any obligation or liability under any such contract or
agreement by reason of or arising out of this Agreement or the receipt by the
Secured Party of any payment relating to any of the Collateral, nor shall the
Secured Party be obligated in any manner to perform any of the obligations of
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 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 Secured Party or to which the
Secured Party may be entitled at any time or times. The Secured Party's sole
duty with respect to the custody, safe keeping and physical preservation of the
Collateral in its possession, under Section 9-207 of the Uniform Commercial Code
of the State or otherwise, shall be to deal with such Collateral in the same
manner as the Secured Party deals with similar property for its own account.

      12.   SECURITIES AND DEPOSITS. The Secured Party may at any time following
and during the continuance of an Event of Default, at its option, transfer to
itself or any nominee any securities constituting Collateral, receive any income
thereon and hold such income as additional Collateral or apply it to the
Obligations. Whether or not any Obligations are due, the Secured Party may,
following and during the continuance of an Event of Default, demand, sue for,
collect, or make any settlement or compromise which it deems desirable with
respect to the Collateral. Regardless of the adequacy of Collateral or any other
security for the Obligations, any deposits or other sums at any time credited by
or due from the Secured Party to Debtor may at any time be applied to or set off
against any of the Obligations then due and owing.

      13.   NOTIFICATION TO ACCOUNT DEBTORS AND OTHER PERSONS OBLIGATED ON
COLLATERAL. If an Event of Default shall have occurred and be continuing, Debtor
shall, at the request of the Secured Party, notify account debtors and other
persons obligated on any of the Collateral of the security interest of the
Secured Party in any account, chattel paper, general intangible, instrument or
other Collateral and that payment thereof is to be made directly to the Secured
Party or to any financial institution designated by the Secured Party as the
Secured Party's agent therefor, and the Secured Party may itself if an Event of
Default shall have occurred and be continuing, without notice to or demand upon
Debtor, so notify account debtors and other persons obligated on Collateral.
After the making of such a request or the giving of any such notification,
Debtor shall hold any proceeds of collection of accounts, chattel paper, general
intangibles, instruments and other Collateral received by Debtor as trustee for
the Secured Party without commingling the same with other funds of Debtor and
shall turn the same over to the Secured Party in the identical form received,
together with any necessary endorsements or assignments. The Secured Party shall
apply the proceeds of collection of accounts, chattel paper, general
intangibles, instruments and other Collateral received by the Secured Party to
the Obligations, such proceeds to be immediately entered after final payment in
cash or other immediately available funds of the items giving rise to them.

      14.   POWER OF ATTORNEY.

            the Secured Party were the absolute owner thereof for all purposes,
            and to do at Debtor's expense, at any time, or from time to time,
            all acts and things which the Secured Party deems necessary to
            protect, preserve or realize upon the Collateral and the Secured
            Party's security interest therein, in order to effect the intent of
            this Agreement, all as fully and effectively as Debtor might do,

            securities and (iii) the execution, delivery and recording, in
            connection with any sale or other disposition of any Collateral, of

                  (b)   to the extent that Debtor's authorization given in
            Section 3 is not sufficient, to file such financing statements with
            respect hereto, with or without Debtor's signature, or a photocopy
            of this Agreement in substitution for a financing statement, as the
            Secured Party may deem appropriate and to execute in Debtor's name
            such financing statements and amendments thereto and continuation
            statements which may require Debtor's signature.

            14.2  RATIFICATION BY COMPANY. To the extent permitted by law,
Debtor hereby ratifies all that said attorneys shall lawfully do or cause to be
done by virtue hereof. This power of attorney is a power coupled with an
interest and shall be irrevocable.

            14.3  NO DUTY ON SECURED PARTY. The powers conferred on the Secured
Party hereunder are solely to protect its interests in the Collateral and shall
not impose any duty upon it to exercise any such powers. The Secured Party shall
be accountable only for the amounts that it actually receives as a result of the
exercise of such powers and neither it nor any of its officers, directors,
employees or agents shall be responsible to Debtor for any act or failure to
act, except for the Secured Party's own gross negligence or willful misconduct.

      15.   REMEDIES. If an Event of Default shall have occurred and be
continuing, the Secured Party may, by delivery of a Default Notice to Debtor,
declare this Agreement to be in default, and the Secured Party shall thereafter
have in any jurisdiction in which enforcement hereof is sought, in addition to
all other rights and remedies, the rights and remedies of a secured party under
the Uniform Commercial Code of the State or of any jurisdiction in which
Collateral is located, including, without limitation, the right to take
possession of the Collateral, and for that purpose the Secured Party may, so far
as Debtor can give authority therefor, enter upon any premises on which the
Collateral may be situated and remove the same therefrom. The Secured Party may
in its discretion require Debtor to assemble all or any part of the Collateral
at such location or locations within the jurisdiction(s) of Debtor's principal
office(s) or at such other locations as the Secured Party may reasonably
designate. Unless the Collateral is perishable or threatens to decline speedily
in value or is of a type customarily sold on a recognized market, the Secured
Party shall give to Debtor at least ten (10) Business Days prior written notice
of the time and place of any public sale of Collateral or of the time after
which any private sale or any other intended disposition is to be made. Debtor
hereby acknowledges that ten (10) Business Days prior written notice of such
sale or sales shall be reasonable notice. In addition, Debtor waives any and all
rights that, it may have to a judicial hearing in advance of the enforcement of
any of the Secured Party's rights hereunder, including, without limitation, its
right following an Event of Default to take immediate possession of the
Collateral and to exercise its rights with respect thereto.

      16.   STANDARDS FOR EXERCISING REMEDIES. To the extent that applicable law
imposes duties on the Secured Party to exercise remedies in a commercially
reasonable manner, Debtor acknowledges and agrees that it is not commercially
unreasonable for the Secured Party (a) to fail to incur expenses reasonably
deemed significant by the Secured Party to prepare Collateral for disposition or
otherwise to complete raw material or work in process into finished goods or
other finished products for disposition, (b) to fail to obtain third party
consents for access to Collateral to be disposed of, or to obtain or, if not
required by other law, to fail to obtain governmental or third party consents
for the collection or disposition of Collateral to be collected or disposed of,
(c) to fail to exercise collection remedies against account debtors or other
persons obligated on Collateral or to remove liens or encumbrances on or any
adverse claims against Collateral, (d) to exercise collection remedies against
account debtors and other persons obligated on Collateral directly or through
the use of collection agencies and other collection specialists, (e) to
advertise dispositions of Collateral through publications or media of general
circulation, whether or not the Collateral is of a specialized nature, (f) to
contact other persons, whether or not in the same business as Debtor, for
expressions of interest in acquiring all or any portion of the Collateral, (g)
to hire one or more professional auctioneers to assist in the disposition of
Collateral, whether or not the collateral is of a specialized nature, (h) to
dispose



                                      -10-
<PAGE>

of Collateral by utilizing Internet sites that provide for the auction of assets
of the types included in the Collateral or that have the reasonable capability
of doing so, or that match buyers and sellers of assets, (i) to dispose of
assets in wholesale rather than retail markets, (j) to disclaim disposition
warranties, (k) to purchase insurance or credit enhancements to insure the
Secured Party against risks of loss, collection or disposition of Collateral or
to provide to the Secured Party a guaranteed return from the collection or
disposition of Collateral, or (l) to the extent deemed appropriate by the
Secured Party, to obtain the services of other brokers, investment bankers,
consultants and other professionals to assist the Secured Party in the
collection or disposition of any of the Collateral. Debtor acknowledges that the
purpose of this Section 16 is to provide non-exhaustive indications of what
actions or omissions by the Secured Party would not be commercially unreasonable
in the Secured Party's exercise of remedies against the Collateral and that
other actions or omissions by the Secured Party shall not be deemed commercially
unreasonable solely on account of not being indicated in this Section 16.
Without limitation upon the foregoing, nothing contained in this Section 16
shall be construed to grant any rights to Debtor or to impose any duties on the
Secured Party that would not have been granted or imposed by this Agreement or
by applicable law in the absence of this Section 16.

      17.   NO WAIVER BY SECURED PARTY, ETC. The Secured Party shall not be
deemed to have waived any of its rights upon or under the Obligations or the
Collateral unless such waiver shall be in writing and signed by the Secured
Party. No delay or omission on the part of the Secured Party in exercising any
right shall operate as a waiver of such right or any other right. A waiver on
any one occasion shall not be construed as a bar to or waiver of any right on
any future occasion. All rights and remedies of the Secured Party with respect
to the Obligations or the Collateral, whether evidenced hereby or by any other
instrument or papers, shall be cumulative and may be exercised singularly,
alternatively, successively or concurrently at such time or at such times as the
Secured Party deems expedient.

      18.   SURETYSHIP WAIVERS BY COMPANY. Debtor waives demand, notice,
protest, notice of acceptance of this Agreement, notice of loans made, credit
extended, Collateral received or delivered or other action taken in reliance
hereon and all other demands and notices of any description. With respect to
both the Obligations and the Collateral, Debtor assents to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of or failure to perfect any security interest
in any Collateral, to the addition or release of any party or person primarily
or secondarily liable, to the acceptance of partial payment thereon and the
settlement, compromising or adjusting of any thereof, all in such manner and at
such time or times as the Secured Party may deem advisable. The Secured Party
shall have no duty as to the collection or protection of the Collateral or any
income thereon, nor as to the preservation of rights against prior parties, nor
as to the preservation of any rights pertaining thereto beyond the safe custody
thereof as set forth in Section 11.2. Debtor further waives any and all other
suretyship defenses.

      19.   MARSHALING. The Secured Party shall not be required to marshal any
present or future collateral security (including but not limited to this
Agreement and the Collateral) for, or other assurances of payment of, the
Obligations or any of them or to resort to such collateral security or other
assurances of payment in any particular order, and all of its




                                      -11-
<PAGE>

rights hereunder and in respect of such collateral security and other assurances
of payment shall be cumulative and in addition to all other rights, however
existing or arising. To the extent that it lawfully may, Debtor hereby agrees
that it will not invoke any law relating to the marshalling of collateral which
might cause delay in or impede the enforcement of the Secured Party's rights
under this Agreement or under any other instrument creating or evidencing any of
the Obligations or under which any of the Obligations is outstanding or by which
any of the Obligations is secured or payment thereof is otherwise assured, and,
to the extent that it lawfully may, Debtor hereby irrevocably waives the
benefits of all such laws.

      20.   PROCEEDS OF DISPOSITIONS; EXPENSES. Debtor shall pay to the Secured
Party on demand any and all expenses, including reasonable attorneys' fees and
disbursements, incurred or paid by the Secured Party in protecting, preserving
or enforcing the Secured Party's rights under or in respect of any of the
Obligations or any of the Collateral. After deducting all of said expenses, the
residue of any proceeds of collection or sale of the Obligations or Collateral
shall, to the extent actually received in cash, be applied to the payment of the
Obligations in such order or preference as the Secured Party may determine,
proper allowance and provision being made for any Obligations not then due. Upon
the final payment and satisfaction in full of all of the Obligations and after
making any payments required by Sections 9-608(a)(1)(C) or 9615(a)(3) of the
Uniform Commercial Code of the State, any excess shall be returned to Debtor,
and Debtor shall remain liable for any deficiency in the payment of the
Obligations.

      21.   OVERDUE AMOUNTS. Until paid, all amounts due and payable by Debtor
hereunder shall be a debt secured by the Collateral and shall bear, whether
before or after judgment, interest at the rate of interest for overdue principal
set forth in the Note.

      22.   GOVERNING LAW; CONSENT TO JURISDICTION. THIS AGREEMENT IS INTENDED
TO TAKE EFFECT AS A SEALED INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE WITHOUT GIVING EFFECT TO ITS
CONFLICT OF LAWS PROVISIONS. Debtor agrees that any suit for the enforcement of
this Agreement may be brought in the courts of the State or any federal court
sitting therein and consents to the non-exclusive jurisdiction of such court and
to service of process in any such suit being made upon Debtor by mail at the
address specified in Article X of the Note. Debtor hereby waives any objection
that it may now or hereafter have to the venue of any such suit or any such
court or that such suit is brought in an inconvenient court.

      23.   WAIVER OF JURY TRIAL. DEBTOR WAIVES ITS RIGHT TO A JURY TRIAL WITH
RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH
THIS AGREEMENT, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY
SUCH RIGHTS OR OBLIGATIONS. Except as prohibited by law, Debtor waives any right
which it may have to claim or recover in any litigation referred to in the
preceding sentence any special, exemplary, punitive or consequential damages or
any damages other than, or in addition to, actual damages. Debtor (i) certifies
that neither the Secured Party nor any representative, agent or attorney of the
Secured Party has represented, expressly or otherwise, that the Secured Party
would not, in the event of




                                      -12-
<PAGE>

litigation, seek to enforce the foregoing waivers and (ii) acknowledges that, in
entering into the Securities Purchase Agreement, the Secured Party is relying
upon, among other things, the waivers and certifications contained in this
Section 23.

      24.   MISCELLANEOUS. The headings of each section of this Agreement are
for convenience only and shall not define or limit the provisions thereof. This
Agreement and all rights and obligations hereunder shall be binding upon Debtor
and its respective successors and assigns, and shall inure to the benefit of the
Secured Party and its successors and assigns. If any term of this Agreement
shall be held to be invalid, illegal or unenforceable, the validity of all other
terms hereof shall in no way be affected thereby, and this Agreement shall be
construed and be enforceable as if such invalid, illegal or unenforceable term
had not been included herein. No amendment, modification, termination or waiver
of any provision of this Agreement shall be effective unless the same shall be
in writing and signed by the Debtor and the Secured Party. This Agreement
constitutes the complete agreement of the parties with respect to the Collateral
currently located or to be located within the jurisdiction of the United States.
This Agreement may be executed in any number of separate counterparts, each of
which shall collectively and separately constitute one agreement. Debtor
acknowledges receipt of a copy of this Agreement.
