hereafter arising and (ii) is not to be construed as an assignment of any
Copyrights, Copyright Licenses, Patents, Patent Licenses, Trademarks or
Trademark Licenses.

         3.       Provisions Relating to Accounts.

         (a)      Anything herein to the contrary notwithstanding, the Grantor

the conditions and obligations to be observed and performed by it thereunder,
all in accordance with the terms of any agreement giving rise to each such
Account. The Lender shall not have any obligation or liability under any
Account (or any agreement giving rise thereto) by reason of or arising out of
this Security Agreement or the receipt by the Lender of any payment relating to
such Account pursuant hereto, nor shall the Lender be obligated in any manner

Account (or any agreement giving rise thereto), to make any payment, to make

action to enforce any performance or to collect the payment of any amounts that
may have been assigned to it or to which it may be entitled at any time or
times.

         (b)      At any time after the occurrence and during the continuation
of an Event of Default, the Lender shall have the right, but not the

its own name or in the name of the Grantor may communicate with account debtors

amount and terms of any Accounts.

         affidavits, notices, reaffirmations and amendments and restatements of
         existing documents, as the Lender may reasonably request) and do all
         such other things as the Lender may reasonably deem necessary,
         appropriate or convenient (i) to assure to the Lender the
         effectiveness and priority of its security interests hereunder,
         including (A) such instruments as the Lender may from time to time
         reasonably request in order to perfect and maintain the security

         hereby and (iii) to otherwise protect and assure the Lender of its
         rights and interests hereunder. To that end, the Grantor authorizes

         description broader and/or less specific than the description of the
         Collateral contained herein, such as "all assets" or "all personal
         property") disclosing the Lender's security interest in any or all of
         the Collateral of the Grantor without the Grantor's signature thereon,
         and further the Grantor also hereby irrevocably makes, constitutes and


                                       6

designate, as the Grantor's attorney-in-fact with full power and for the limited
purpose to sign in the name of the Grantor any such financing statements

similar documents that in the Lender's reasonable discretion would be necessary,
appropriate or convenient in order to perfect and maintain perfection of the
security interests granted hereunder, such power, being coupled with an
interest, being and remaining irrevocable so long as the Secured Obligations
remain unpaid. Each Grantor hereby agrees that a carbon, photographic or other
reproduction of this Security Agreement or any such financing statement is
sufficient for filing as a financing statement by the Lender without notice
thereof to the Grantor wherever the Lender may in its sole discretion desire to
file the same. In the event for any reason the law of any jurisdiction other
than New York becomes or is applicable to the Collateral of the Grantor or any
part thereof, or to any of the Secured Obligations, the Grantor agrees to
execute and deliver all such instruments and to do all such other things as the
Lender in its sole discretion reasonably deems necessary, appropriate or
convenient to preserve, protect and enforce the security interests of the Lender
under the law of such other jurisdiction (and, if the Grantor shall fail to do
so promptly upon the request of the Lender, then the Lender may execute any and
all such requested documents on behalf of the Grantor pursuant to the power of
attorney granted hereinabove). If any Collateral is in the possession or control
of the Grantor's agents and the Lender so requests, the Grantor agrees to notify
such agents in writing of the Lender's security interest therein and, upon the
Lender's request, instruct them to hold all such Collateral for the account of
the holders of the Secured Obligations and subject to the Lender's instructions.
Each Grantor agrees to maintain its books and records to reflect the security
interest of the Lender in the Collateral.

     (e)     Control. Execute and deliver all agreements, assignments,
instruments or other documents as the Lender shall reasonably request for the
purpose of obtaining and maintaining control within the meaning of the UCC with
respect to any Collateral consisting of Deposit Accounts, Investment Property,
Letter-of-Credit Rights and Electronic Chattel Paper.

     (f)     Collateral held by Warehouseman, Bailee, etc. If any Collateral
with a fair market value in excess of $100,000 is at any time in the possession
or control of a warehouseman, bailee, agent or processor of the Grantor, (i)
notify the Lender of such possession or control, (ii) notify such Person of the
Lender's security interest in such Collateral, (iii) instruct such Person to
hold all such Collateral for the Lender's account and subject to the Lender's
instructions and (iv) use its reasonable efforts to obtain an acknowledgement
from such Person that it is holding such Collateral for the benefit of the
Lender.

     (g)     Treatment of Accounts. Not grant or extend the time for payment of
any Account in excess of $100,000, or compromise or settle any Account for less
than the full amount thereof, or release any Person or property, in whole or in
part, from payment thereof, or allow any credit or discount thereon, in each
case other than as normal and customary in the ordinary course of the Grantor's
business or as required by law.

     (h)     Covenants Relating to Copyrights. Other than any Copyright that
the Board of Directors of the Grantor deems not material to the conduct of its
business:

             (i)     Not do any act or knowingly omit to do any act whereby any
     material Copyright may become invalidated and (A) not do any act, or
     knowingly omit to do any act, whereby any material Copyright may become
     injected into the public domain; (B) notify the Lender immediately if it
     knows that any material Copyright may become injected into the public
     domain or of any adverse determination or development (including without
     limitation, the institution of, or any such determination or development in
     any court or tribunal in the United States or any other country) regarding
     the Grantor's ownership of any

                                       7



                  such Copyright or its validity; (C) take all necessary steps
                  as it shall deem appropriate under the circumstances, to
                  maintain and pursue each application (and to obtain the
                  relevant registration) and to maintain each registration of
                  each material Copyright owned by the Grantor including,
                  without limitation, filing of applications for renewal where
                  necessary; and (D) promptly notify the Lender of any material
                  infringement of any material Copyright of the Grantor of
                  which it becomes aware and take such actions as it shall
                  reasonably deem appropriate under the circumstances to
                  protect such Copyright, including, where appropriate, the
                  bringing of suit for infringement, seeking injunctive relief
                  and seeking to recover any and all damages for such
                  infringement.

                           (ii)     Not make any assignment or agreement in
                  conflict with the security interest in the Copyrights of the
                  Grantor hereunder.

                  Notwithstanding in this Agreement shall prevent the Grantor
                  from discontinuing the use of any Copyright or pursuing the
                  application for any such Copyright if such discontinuance is,
                  in the judgment of its Board of Directors, desirable in the
                  conduct to the conduct of its business.


                  (i)      Covenants Relating to Patents and Trademarks. Other
         than any Patent or Trademark that the Board of Directors of the Grantor
         deems not material to the conduct of its business:

                           (i)      (A) Continue to use each registered
                  Trademark on each and every trademark class of goods
                  applicable to its current line as reflected in its current
                  catalogs, brochures and price lists in order to maintain such
                  registered Trademark in full force free from any claim of
                  abandonment for non-use, (B) maintain as in the past the
                  quality of products and services offered under such
                  registered Trademark, (C) employ such registered Trademark
                  with the appropriate notice of registration, (D) not adopt or
                  use any mark that is confusingly similar or a colorable
                  imitation of such registered Trademark unless the Lender
                  shall obtain a perfected security interest in such mark
                  pursuant to this Security Agreement, and (E) not (and not
                  permit any licensee or sublicensee thereof to) do any act or
                  knowingly omit to do any act whereby any registered Trademark
                  may become invalidated.

                           (ii)     Not do any act, or omit to do any act,
                  whereby any Patent may become abandoned or dedicated.

                           (iii)    Notify the Lender immediately if it knows
                  that any application or registration relating to any Patent
                  or registered Trademark may become abandoned or dedicated, or
                  of any adverse determination or development (including,
                  without limitation, the institution of, or any such
                  determination or development in, any proceeding in the United
                  States Patent and Trademark Office or any court or tribunal in
                  any country) regarding the Grantor's ownership of any Patent
                  or registered Trademark or its right to register the same or
                  to keep and maintain the same.

                           (iv)     Whenever the Grantor, either by itself or
                  through an agent, employee, licensee or designee, shall file
                  an application for the registration of any Patent or
                  registered Trademark with the United States Patent and
                  Trademark Office or any similar office or agency in any other
                  country or any political subdivision thereof, the Grantor
                  shall report such filing to the Lender within five Business
                  Days after the last day of the fiscal quarter in which such
                  filing occurs. Upon request of the Lender, the Grantor shall
                  execute and deliver any and all agreements, instruments,
                  documents and papers as the Lender may reasonably request to
                  evidence the security interest of the Lender in any Patent or
                  registered Trademark


                                       8



                  and the goodwill and general intangibles of the Grantor
                  relating thereto or represented thereby.

                           (v)      Take all reasonable and necessary steps,
                  including, without limitation, in any proceeding before the
                  United States Patent and Trademark Office, or any similar
                  office or agency in any other country or any political
                  subdivision thereof, to maintain and pursue each application
                  (and to obtain the relevant registration) and to maintain each
                  registration of the Patents and Trademarks, including, without
                  limitation, filing of applications for renewal, affidavits of
                  use and affidavits of incontestability.

                           (vi)     Promptly notify the Lender after it learns
                  that any Patent or registered Trademark included in the
                  Collateral is infringed, misappropriated or diluted by a third
                  party and promptly sue for infringement, misappropriation or
                  dilution, to seek injunctive relief where appropriate and to
                  recover any and all damages for such infringement,
                  misappropriation or dilution, or to take such other actions as
                  it shall reasonably deem appropriate under the circumstances
                  to protect such Patent or Trademark.

                           (vii)    Not make any assignment or agreement in
                  conflict with the security interest in the Patents or
                  Trademarks of the Grantor hereunder.

                  Nothing in this Agreement shall prevent any Grantor from
                  discontinuing the use of any Trademark or Patent or pursuing
                  the application of any such Patent or Trademark if such
                  discontinuance is, in the judgment of its Board of Directors,
                  desirable in the conduct of its business.

                  (j)      Commercial Tort Claims.

                           (i)      Promptly notify the Lender in writing of the
                  initiation of any Commercial Tort Claim in excess of
                  $1,000,000 before any Governmental Authority by or in favor of
                  the Grantor or any of its Subsidiaries.

                           (ii)     Execute and deliver such statements,
                  documents and notices and do and cause to be done all such
                  things as the Lender amy reasonably deem necessary,
                  appropriate or convenient, or as are required by law, to
                  create, perfect and maintain the Lender's security interest in
                  any Commercial Tort Claim.

         6.       Advances by Holders of the Secured Obligations. On failure of
the Grantor to perform any of the covenants and agreements contained herein in a
material respect, the Lender may, as its sole option and in its sole discretion,
perform the same and in so doing may expend such sums as the Lender may
reasonably deem advisable in the performance thereof, including, without
limitation, the payment when due and payable of any insurance premiums or taxes,
a payment to obtain a release of a lien or potential lien, expenditures made in
defending against any adverse claim and all other expenditures that the Lender
may make for the protection of the security hereof or that may be compelled to
make by operation of applicable law. All such sums and out-of-pocket amounts so
expended shall be repayable by the Grantor promptly upon timely notice thereof
and demand therefor, shall constitute additional Secured Obligations and shall
bear interest from the date said amounts are demanded at the default rate
specified in the Promissory Note. No such performance of any covenant or
agreement by the Lender on behalf of the Grantor, and no such advance or
expenditure therefor, shall relieve the Grantor of any default under the terms
of this Security Agreement, the other Loan Documents or any other documents
relating to the Secured Obligations. The Lender may make any payment hereby
authorized in accordance with any bill or statement procured from the
appropriate public office or holder of the claim to be discharged without
inquiry into the accuracy of such bill or statement or into the validity of any
tax assessment, sale, forfeiture, tax lien, title or claim except to the extent
such payment is


                                       9

being contested in good faith by the Grantor in appropriate proceedings and
against which adequate reserves are being maintained in accordance with GAAP.

         7.       Remedies.

         (a)      General Remedies. Upon the occurrence of an Event of Default
and during the continuation thereof, the Lender shall have, in addition to the
rights and remedies provided herein, in the Promissory Note, in any other
documents relating to the Secured Obligations, or by applicable law (including,
without limitation, levy of attachment and garnishment), the rights and
remedies of a secured party under the UCC of the jurisdiction applicable to the
affected Collateral and, further, the Lender may, with or without judicial
process or the aid and assistance of others, (i) enter on any premises on which
any of the Collateral may be located and, without resistance or interference by
the Grantor, take possession of the Collateral, (ii) dispose of any Collateral
on any such premises, (iii) require the Grantor to assemble and make available
to the Lender at the expense of the Grantor any Collateral at any place and
time designated by the Lender that is reasonably convenient to both parties,
(iv) remove any Collateral from any such premises for the purpose of offering
sale or other disposition thereof, and/or (v) without demand and without
advertisement, notice, hearing or process of law, all of which the Grantor
hereby waives to the fullest extent permitted by applicable law, at any place
and time or times, sell and deliver any or all Collateral held by or for it at
public or private sale, by one or more contracts, in one or more parcels, for
cash, upon credit or otherwise, at such prices and upon such terms as the
Lender deems advisable, in its sole discretion (subject to any and all
mandatory legal requirements). The Grantor acknowledges that any private sale
referenced above may be at prices and on terms less favorable to the seller
than the prices and terms that might have been obtained at a public sale and
agrees that such private sale shall be deemed to have been made in a
commercially reasonable manner. Neither the Lender's compliance with the
applicable law nor its disclaimer of warranties relating to the Collateral
shall be considered to adversely affect the commercial reasonableness of any
sale. In addition to all other sums due the Lender with respect to the Secured
Obligations, the Grantor shall pay the Lender all reasonable documented costs
and out-of-pocket expenses incurred by the Lender including, but not limited
to, reasonable attorneys' fees, the allocated cost of internal counsel and
court costs, in obtaining or liquidating the Collateral, in enforcing payment
of the Secured Obligations, or in the prosecution or defense of any action or
proceeding by or against the Lender or the Grantor concerning any matter
arising out of or connected with this Security Agreement, any Collateral or the
Secured Obligations, including, without limitation, any of the foregoing
arising in, arising under or related to a case under any bankruptcy, insolvency
or similar laws. To the extent the rights of notice cannot be legally waived
hereunder, the Grantor agrees that any requirement of reasonable notice shall
be met if such notice is personally served on or mailed, postage prepaid, to
the Grantor in accordance with the notice provisions of the Promissory Note at
least ten (10) Business Days before the time of sale or other event giving rise
to the requirement of such notice. The Lender shall not be obligated to make
any sale or other disposition of the Collateral regardless of notice having
been given. To the extent permitted by applicable law, the Lender may be a
purchaser at any such sale. To the extent permitted by applicable law, the
Grantor hereby waives all of its rights of redemption with respect to any such
sale. Subject to the provisions of applicable law, the Lender may postpone or
cause the postponement of the sale of all or any portion of the Collateral by
announcement at the time and place of such sale, and such sale may, without
further notice, to the extent permitted by law, be made at the time and place
to which the sale was postponed, or the Lender may further postpone such sale by
announcement made at such time and place.

         (b)      Remedies relating to Accounts. Upon the occurrence of an
Event of Default and during the continuation thereof, whether or not the Lender
has exercised any or all of its rights and remedies hereunder and in each case
in compliance with and to the extent permitted under applicable law (i) the
Grantor will promptly upon request of the Lender instruct all account debtors
to remit all payments in respect of Accounts to a mailing location selected by
the Lender and (ii) the Lender shall have the right to enforce the Grantor's
rights against its customers and account debtors, and the Lender or its
designee may notify the Grantor's customers and account debtors that the
Accounts of the Grantor have been assigned to the Lender or of the Lender's
security interests therein, and may (either in its own name or in the name of
the Grantor or both)


                                      10

demand, collect (including without limitation by way of a lockbox arrangement),
receive, take receipt for, sell, sue for, compound, settle, compromise and give
acquittance for any and all amounts due or to become due on any Account, and,
in the Lender's discretion, file any claim or take any other action or
proceeding to protect and realize upon the security interest of the holders of
the Secured Obligations in the Accounts; provided, however, that Grantor and
the Lender must comply with assignments of payments to providers as set forth
in 42 U.S.C. Section 1395, as may be amended or any subsequent changes thereto.
The Grantor acknowledges and agrees that the Proceeds of its Accounts remitted
to or on behalf of the Lender in accordance with the provisions hereof shall be
solely for the Lender's own convenience and that the Grantor shall not have any
right, title or interest in such Accounts or in any such other amounts except
as expressly provided herein. The Lender shall have no liability or
responsibility to the Grantor for acceptance of a check, draft or other order
for payment of money bearing the legend "payment in full" or words of similar
import or any other restrictive legend or endorsement or be responsible for
determining the correctness of any remittance. The Grantor hereby agrees to
indemnify the Lender from and against all liabilities, damages, losses, actions,
claims, judgments, costs, expenses, charges and reasonable attorneys' fees
suffered or incurred by the Lender (each, an "Indemnified Party") arising out
of its maintenance of the foregoing arrangements except as relating to or
arising out of the gross negligence or willful misconduct of an indemnified
Party or its officers, employees or agents. In the case of any investigation,
litigation or other proceeding, the foregoing indemnity shall be effective
whether or not such investigation, litigation or proceeding is brought by
the Grantor, its directors, shareholders or creditors or an Indemnified Party
or any other Person or any other Indemnified Party is otherwise a party
thereto.

     (c)     Access. In addition to the rights and remedies hereunder, upon the
occurrence of an Event of Default and during the continuation thereof, the
Lender shall have the right to enter and remain upon the various premises of
the Grantor without cost or charge to the Lender, and use the same, together
with materials, supplies, books and records of the Grantor for the purpose of
collecting and liquidating the Collateral, or for preparing for sale and
conducting the sale of the Collateral, whether by foreclosure, auction or
otherwise. In addition, the Lender may remove Collateral, or any part thereof,
from such premises and/or any records with respect thereto, in order to
effectively collect or liquidate such Collateral. Notwithstanding the
foregoing, prior to receiving information from the Grantor under this Security
Agreement that contains patient information subject to: (i) the state privacy
laws, (ii) the Drug Abuse Prevention, Treatment and Rehabilitation Act, 42
U.S.C. 290ee3 et. seq. or (iii) the Health Insurance Portability and
Accountability Act of 1996, 42 U.S.C. 1320d et. seq., or (iv) regulations
promulgated pursuant to the foregoing statutes, the Lender agrees to execute an
agreement reasonably satisfactory to the Lender that complies with the
requirements relating to "business associates" as set forth in 45 CFR 502(e)(1)
and any applicable Laws.

     (d)     Nonexclusive Nature of Remedies. Failure by the Lender to exercise
any right, remedy or option under this Security Agreement, the Promissory Note,
any other documents relating to the Secured Obligations, or as provided by law,
or any delay by the Lender in exercising the same, shall not operate as a
waiver of any such right, remedy or option. No waiver hereunder shall be
effective unless it is in writing, signed by the party against whom such waiver
is sought to be enforced and then only to the extent specifically stated, which
in the case of the Lender shall only be granted as provided herein. The rights
and remedies of the Lender under this Security Agreement shall be cumulative
and not exclusive of any other right or remedy that the Lender may have.

     (e)     Retention of Collateral. To the extent permitted under applicable
law, in addition to the rights and remedies hereunder, upon the occurrence of
an Event of Default, the Lender may, after providing the notices required by
Sections 9-620 and 9-621 of the UCC or otherwise complying with the
requirements of applicable law of the relevant jurisdiction, accept or retain
all or any portion of the Collateral in satisfaction of the Secured
Obligations. Unless and until the Lender shall have provided such notices,
however, the Lender shall not be deemed to have accepted or retained any
Collateral in satisfaction of any Secured Obligations for any reason.

                                      11

     (f)  Deficiency. In the event that the proceeds of any sale, collection or
realization are insufficient to pay all amounts to which the Lender is legally
entitled, the Grantor shall be liable for the deficiency, together with
interest thereon at the default rate specified in the Promissory Note, together
with the costs of collection and reasonable attorneys' fees (including the
allocated cost of internal counsel). Any surplus remaining after the full
payment and satisfaction of the Secured Obligations shall be returned to the
Grantor or to whomsoever a court of competent jurisdiction shall determine to
be entitled thereto.

     8.   Rights of the Lender.

     (a)  Power of Attorney. In addition to other powers of attorney contained
herein, to the extent permitted by applicable law, the Grantor hereby designates
and appoints the Lender and each of its designees or agents, as attorney-in-fact
of the Grantor, irrevocably and with power of substitution, with authority to
take any or all of the following actions upon the occurrence and during the
continuation of an Event of Default:

          (i)       to demand, collect, settle, compromise and adjust, and give
     discharges and releases concerning the Collateral, all as the Lender may
     reasonably deem appropriate;

          (ii)      to commence and prosecute any actions at any court for the
     purposes of collecting any of the Collateral and enforcing any other right
     in respect thereof;

          (iii)     to defend, settle or compromise any action brought and, in
     connection therewith, give such discharge or release as the Lender may
     reasonably deem appropriate;

          (iv)      to the extent permitted by applicable law and at all times
     in accordance therewith, to receive, open and dispose of mail addressed to
     the Grantor and endorse checks (other than for insurance premiums), notes,
     drafts, acceptances, money orders, bills of lading, warehouse receipts or
     other instruments or documents evidencing payment, shipment or storage of
     the goods giving rise to the Collateral on behalf of and in the name of
     the Grantor, or securing, or relating to such Collateral;

          (v)       to pay or discharge taxes, liens, security interests or
     other encumbrances levied or placed on or threatened against the
     Collateral;

          (vi)      to direct any parties liable for any payment in connection
     with any of the Collateral (other than insurance premiums) to make payment
     of any and all monies due and to become due thereunder directly to the
     Lender or as the Lender shall direct;

          (vii)     except as limited by applicable law, to receive payment of
     and receipt for any and all monies, claims, and other amounts due and to
     become due at any time in respect of or arising out of any Collateral;

          (viii)    to sell, assign, transfer, make any agreement in respect
     of, or otherwise deal with or exercise rights in respect of, any
     Collateral or the goods or services that have given rise thereto, as fully
     and completely as though the Lender were the absolute owner thereof for
     all purposes;

          (ix)      to adjust and settle claims under any insurance policy
     under which the Grantor or the Lender is a beneficiary or additional
     insured;

          (x)       to execute and deliver all assignments, conveyances,
     statements, financing statements, renewal financing statements, security
     and pledge agreements, affidavits, notices and other agreements,
     instruments and documents that the Lender may reasonably deem

                                       12





         appropriate in order to perfect and maintain the security interests and
         liens granted in this Security Agreement and in order to fully
         consummate all of the transactions contemplated there in:

                  (xi)     to institute any foreclosure proceedings that the
         Lender may reasonably deem appropriate; and

                  (xii)    to do and perform all such other acts and things as
         the Lender may reasonably deem appropriate or convenient in connection
         with the Collateral.

         This power of attorney is a power coupled with an interest and shall
be irrevocable for so long as any of the Secured Obligations shall remain
outstanding. The Lender shall be under no duty to exercise or withhold the
exercise of any of the rights, powers, privileges and options expressly or
implicitly granted to the Lender in this Security Agreement, and shall not be
liable for any failure to do so or any delay in doing so. This power of
attorney is conferred on the Lender solely to protect, preserve and realize
upon its security interest in the Collateral.

         (b)      The Lender's Duty of Care. Other than the exercise of
reasonable care to assure the safe custody of the Collateral while being held
by the Lender hereunder, the Lender shall have no duty or liability to preserve
rights pertaining thereto, it being understood and agreed that the Grantor
shall be responsible for preservation of all rights in the Collateral, and the
Lender shall be relieved of all responsibility for the Collateral upon
surrendering it or tendering the surrender of it to the Grantor. The Lender
shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if such Collateral is accorded
treatment substantially equal to that which the Lender accords its own
property, which shall be no less than the treatment employed by a reasonable
and prudent agent in the industry, it being understood that the Lender shall
not have responsibility for taking any necessary steps to preserve rights
against any parties with respect to any of the Collateral. In the event of a
public or private sale of Collateral pursuant to Section 7 hereof, the Lender
shall have no obligation to clean, repair or otherwise prepare the Collateral
for sale.

         9.       Applications of Proceeds. Upon the occurrence and during the
continuation of an Event of Default, any payments in respect of the Secured
Obligations and any proceeds of the Collateral will be applied in reduction of
the Secured Obligations in the order determined by the Lender and the Grantor
irrevocably waives the right to direct the application of such payments and
proceeds and acknowledges and agrees that the Lender shall have the continuing
and exclusive right to apply and reapply any and all such payments and proceeds
in the Lender's sole discretion, notwithstanding any entry to the contrary upon
any of its books and records.

         10.      Continuing Agreement.

         (a)      This Security Agreement shall be a continuing agreement in
every respect and shall remain in full force and effect so long as any of the
Secured Obligations remains outstanding.

         (b)      This Security Agreement shall continue to be effective or be
automatically reinstated, as the case may be, if at any time payment, in whole
or in part, of any of the Secured Obligations is rescinded or must otherwise be
restored or returned by the Lender as a preference, fraudulent conveyance or
otherwise under any bankruptcy, insolvency or similar law, all as though such
payment had not been made; provided that in the event payment of all or any
part of the Secured Obligations is rescinded or must be restored or returned,
all reasonable costs and expenses (including, without limitation, attorneys'
fees, the allocated cost of internal counsel and disbursements) incurred by the
Lender in defending and entering such reinstatement shall be deemed to be
included as a part of the Secured Obligations.


                                       13





         11.      Amendments and Waivers. This Security Agreement and the
provisions hereof may not be amended, waived, modified, changed, discharged or
terminated except with the consent of the Grantor and the Collateral Agent.

         12.      Successors in Interest.

         (a)      This Security Agreement shall create a continuing security
interest in the Collateral and shall be binding upon the Grantor, its
successors and assigns, and shall inure, together with the rights and remedies
of the Lender hereunder, to the benefit of the Lender and its successors and
permitted assigns; provided however, that the Grantor may not assign its rights
or delegate its duties hereunder except as consented to by the Collateral Agent.

         (b)      The Grantor acknowledges and consents to the collateral
assignment by the Lender of its rights hereunder to the Collateral Agent.

         13.      Notices. All notices and other communications required or
