                (n) Patents, Trademarks, Etc. Each Grantor shall notify the
Collateral Agent promptly of its acquisition after the Effective Date of any
Patent, Patent License, Trademark or Trademark License. In the event that any
Patent, Patent License, Trademark or Trademark License is infringed,
misappropriated or diluted by a third party, each Grantor shall notify the
Collateral Agent promptly after they learn thereof and shall, if such Grantor
reasonably determines that inaction would materially affect the economic value
of such item(s), promptly sue for infringement, misappropriation or dilution and
to recover any and all damages for such



                                      -10-
   11

infringement, misappropriation or dilution, or take such other actions as such
Grantor shall reasonably deem appropriate under the circumstances to protect
such Patent, Patent License, Trademark or Trademark License. In no event shall
any Grantor, either itself or through any agent, employee or licensee, file an
application for the registration of any Patent or Trademark with the United
States Patent and Trademark Office, unless, upon issuance such Grantor shall
deliver such documents and papers that the Collateral Agent may reasonably
request to evidence the Security Interests in such Patent or Trademark and the
goodwill and general intangibles of such Grantor relating thereto or represented
thereby.

                SECTION 6. Collateral Agent Appointed Attorney-in-Fact. Each
Grantor hereby irrevocably appoints the Collateral Agent such Grantor's
attorney-in-fact, with full authority in the place and stead of such Grantor and
in the name of such Grantor or otherwise, from time to time after the occurrence
and during the continuation of an Event of Default, to take any action, to
execute any instruments and to exercise any rights, privileges, options,
elections or powers of such Grantor pertaining or relating to the Collateral
which the Collateral Agent may deem necessary or desirable to preserve and
enforce its security interest in the Collateral and otherwise to accomplish the
purposes of this Security Agreement. The Collateral Agent shall not have any
duty to take any such action, to execute any such instrument, to exercise any
such rights, privileges, options, including, without limitation, termination
options, elections or powers or to sell or otherwise to realize upon any of the
Collateral, as hereinafter authorized, and the Collateral Agent shall not be
responsible for any failure to do so or delay in so doing.

                SECTION 7. Reporting and Recordkeeping. Each Grantor covenants
and agrees with the Collateral Agent and the Secured Parties that from and after
the date of this Agreement and until the payment and performance in full of all
Secured Obligations:

                (a) Maintenance of Records Generally. Such Grantor will keep and
maintain at its own cost and expense records of the Collateral, in substantially
the form, scope and detail as Grantor currently keeps such records, including,
without limitation, a record of all payments received and all credits granted
with respect to the Collateral. For the Collateral Agent's and the Secured
Parties' further security, such Grantor agrees that the Collateral Agent and the
Secured Parties shall have a security interest in all of the Grantor's books and
records pertaining to the Collateral and, upon the occurrence and during the
continuation of any Potential Default or Event of Default, the Grantor shall
deliver and turn over full and complete copies of any such books and records to
the Collateral Agent or to its representatives at any time on demand of the
Collateral Agent. Prior to the occurrence of a Potential Default or an Event of
Default and upon reasonable notice from the Collateral Agent, such Grantor shall
permit any representative of the Collateral Agent, at reasonable times and
reasonable intervals upon one Business Day's notice, to inspect such books and
records and will provide photocopies thereof to the Collateral Agent.

                (b) Further Identification of Collateral. Following the
occurrence and during the continuation of an Event of Default, such Grantor will
if so requested by the Collateral Agent furnish to the Collateral Agent, as
often as the Collateral Agent reasonably requests, statements and schedules
further identifying and describing the Collateral and such other reports in



                                      -11-
   12

connection with the Collateral as the Collateral Agent may reasonably request,
all in reasonable detail.

                (c) Notices. Each Grantor will advise the Collateral Agent
promptly, in reasonable detail, (i) of any material Lien or claim made or
asserted against any of the Collateral, (ii) of any material adverse change in
the composition of the Collateral, and (iii) of the occurrence of any other
event which would have a substantial likelihood of having a material adverse
effect on the aggregate value of the Collateral or on the validity, perfection
or priority of the Security Interests.

                SECTION 8. Collateral Agent May Perform. If any Grantor fails to
perform any agreement contained herein, the Collateral Agent may (but shall not
be obligated to) itself perform, or cause performance of, such agreement. The
Grantors shall reimburse the Collateral Agent on demand for any reasonable
amounts paid or any reasonable expenses incurred by the Collateral Agent in good
faith in connection therewith.

                SECTION 9. Collateral Agent's Duties. The powers conferred on
the Collateral Agent hereunder are solely to protect its interest in the
Collateral for the benefit of the Secured Parties and shall not impose any duty
upon it to exercise any such powers. Except as expressly provided herein, the
Collateral Agent shall have no duty to take any steps to preserve the security
interest granted hereby.

                SECTION 10. Realization upon Collateral. (a) If an Event of
Default shall occur and be continuing, the Collateral Agent may, and at the
request of the Majority Secured Parties shall, (i) take any and all action
necessary or appropriate to collect any and all amounts payable under or with
respect to the Collateral, (ii) apply any and all amounts in the Collateral
Account to the Secured Obligations in accordance with Section 11 hereof, (iii)
take possession of the Collateral forthwith or at any time thereafter, in which
case the Grantor shall marshal and deliver the Collateral to the Collateral
Agent at such time and place as the Collateral Agent may reasonably specify, and
(iv) sell the whole or, from time to time, any part of the Collateral, by
private or public sale, in such order or otherwise in such manner as the
Majority Secured Parties may elect in their sole discretion. The Collateral
Agent shall have, with respect to the Collateral, in addition to any other
rights and remedies which may be available to it at law or in equity or pursuant
to this Security Agreement, any Related Document or any other contract or
agreement, all rights and remedies of a secured party under any applicable
version of the Uniform Commercial Code of the relevant jurisdictions relating to
the Collateral, and it is expressly agreed that if the Collateral Agent should
proceed to dispose of or utilize the Collateral, or any part thereof, in
accordance with the provisions of said versions of the Uniform Commercial Code,
ten days' notice by the Collateral Agent to each Grantor of the intended
disposition of such Grantor's collateral shall be deemed to be reasonable notice
under any such provision requiring such notice. Any sale of Collateral by the
Collateral Agent may be made on such terms as the Majority Secured Parties may
reasonably specify, without assuming any credit risk and without any obligation
to advertise or give notice of any kind other than that necessary under
applicable law. The Collateral Agent and the Secured Parties shall incur no
liability as a result of the sale of the Collateral, or any part



                                      -12-
   13

thereof, at any private or public sale. Except as otherwise stated herein each
Grantor hereby waives, to the extent permitted by applicable law, any claims
against the Collateral Agent and the Secured Parties arising by reason of the
fact that the price at which Collateral may have been sold at such a private
sale was less than the price which might have been obtained at a public sale or
was less than the aggregate amount of the Secured Obligations, even if the
Collateral Agent accepts the first offer received and does not offer such
Collateral to more than one possible purchaser. In exercising its rights under
this Section 10, the Collateral Agent will act in a commercially reasonable
manner and comply with all applicable laws, including Section 9-207 of the
Uniform Commercial Code.

                The Collateral Agent or any Secured Party may be the purchaser
of any or all of the Collateral so sold at any public sale (or, if the
Collateral is of a type customarily sold in a recognized market or is of a type
which is the subject of widely distributed standard price quotations or if
otherwise permitted under applicable law, at any private sale) and thereafter
hold the same, absolutely, free from any right or claim of whatsoever kind. The
Grantors will execute and deliver such documents and take such other action as
the Collateral Agent deems reasonably necessary or advisable in order that any
such sale may be made in compliance with law. Upon any such sale the Collateral
Agent shall have the right to deliver, assign and transfer to the purchaser
thereof the Collateral so sold. Each purchaser at any such sale shall hold the
Collateral so sold to it absolutely, free from any claim or right of any kind,
including any equity or right of redemption of the Grantors. To the extent
permitted by law, each Grantor hereby specifically waives all rights of
redemption, stay or appraisal which it has or may have under any law now
existing or hereafter adopted. The notice (if any) of such sale shall (1) in
case of a public sale, state the time and place fixed for such sale, and (2) in
the case of a private sale, state the day after which such sale may be
consummated. Any such public sale shall be held at such time or times within
ordinary business hours and at such place or places as the Collateral Agent may
fix in the notice of such sale. At any such sale the Collateral may be sold in
one lot as an entirety or in separate parcels, as the Collateral Agent may
determine. The Collateral Agent shall not be obligated to make any such sale
pursuant to any such notice. The Collateral Agent may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be so
adjourned. In case of any sale of all or any part of the Collateral on credit or
for future delivery, the Collateral so sold may be retained by the Collateral
Agent until the selling price is paid by the purchaser thereof, but the
Collateral Agent shall not incur any liability in case of the failure of such
purchaser to take up and pay for the Collateral so sold and, in case of any such
failure, such Collateral may again be sold upon like notice. The Collateral
Agent, instead of exercising the power of sale herein conferred upon it, may
proceed by a suit or suits at law or in equity to foreclose the Security
Interests and sell the Collateral, or any portion thereof, under a judgment or
decree of a court or courts of competent jurisdiction. The Grantors shall remain
liable, jointly and severally, for any deficiency.

                (b) Following the occurrence and during the continuation of an
Event of Default, for the purpose of enforcing any and all rights and remedies
under this Agreement, the Collateral Agent may (i) require the Grantors to, and
the Grantors agree that they will, at their



                                      -13-
   14

expense and upon the request of the Collateral Agent, forthwith assemble all or
any part of the Collateral as directed by the Collateral Agent and make it
available at a place designated by the Collateral Agent which is, in the
Collateral Agent's reasonable opinion, reasonably convenient to the Collateral
Agent and the Grantors, whether at the premises of a Grantor or otherwise, (ii)
to the extent permitted by applicable law, enter, with or without process of law
and without breach of the peace, any premise where any of the Collateral is or
may be located and, without charge or liability to the Collateral Agent, seize
and remove such Collateral from such premises, (iii) have access to and use the
Grantors' books and records, computers and software relating to the Collateral,
and (iv) prior to the disposition of the Collateral, store or transfer such
Collateral without charge in or by means of any storage or transportation
facility owned or leased by the Grantors, process, repair or recondition such
Collateral or otherwise prepare it for disposition in any manner and to the
extent the Collateral Agent deems appropriate and, in connection with such
preparation and disposition, use without charge any trademark, trade name,
copyright, patent or technical process used by the Grantors (at the expense of
the Grantors).

                (c) Without limiting the generality of the foregoing, if any
Event of Default has occurred and is continuing:

                        (i) the Collateral Agent may license, or sublicense,
consistent with such Grantor's rights therein, whether general, special or
otherwise, and whether on an exclusive or non-exclusive basis, any Patents or
Trademarks included in the Collateral throughout the world for such term or
terms, on such conditions and in such manner as the Collateral Agent shall in
its sole discretion determine;

                        (ii) the Collateral Agent may (without assuming any
obligations or liability thereunder), at any time and from time to time, enforce
(and shall have the exclusive right to enforce) against any licensee or
sublicensee all rights and remedies of the Grantors in, to and under any Patent
Licenses or Trademark Licenses and take or refrain from taking any action under
any thereof, and each Grantor hereby releases the Collateral Agent and each of
the Secured Parties from, and agrees to hold the Collateral Agent and each of
the Secured Parties free and harmless from and against any claims arising out
of, any lawful action so taken or lawfully omitted to be taken with respect
thereto except for the Collateral Agent's or such Secured Parties' bad faith,
negligence or wilful misconduct as determined by a final and nonappealable
decision of a court of competent jurisdiction; and

                        (iii) upon request by the Agent, the Grantors will
execute and deliver to the Collateral Agent powers of attorney, in form and
substance satisfactory to the Collateral Agent, for the implementation of any
lease, assignment, license, sublicense, grant of option, sale or other
disposition of a Patent or Trademark. In the event of any such disposition
pursuant to this Section 10, the Grantors shall to the extent possible, supply
their know-how and expertise relating to the manufacture and sale of the
products bearing Trademarks or the products or services made or rendered in
connection with Patents, and its customer lists and other records relating to
such Patents or Trademarks and to the distribution of said products, to the
Collateral Agent.

   15

                SECTION 11. Application of Proceeds. The Collateral Agent shall
apply the proceeds of any realization upon or sale of the whole or any part of
the Collateral, after deducting all reasonable costs and expenses of collection,
retaking, handling, storage, preparation, sale and delivery (including, without
limitation, reasonable counsel's fees and expenses) incurred by it in connection
with such realization or sale to the payment of the Secured Obligations in
accordance with the Participation Agreement, and the Grantors shall remain in
all respects liable to the Collateral Agent and the Secured Parties for any
unrecovered balance owing to them.

                SECTION 12. Waiver of Stays, etc. To the fullest extent that the
Grantors may lawfully so agree, each Grantor agrees that it will not at any time
plead, claim or take the benefit of any appraisement, valuation, stay,
extension, moratorium or redemption law now or hereafter in force to prevent or
delay the enforcement of this Security Agreement or the absolute sale of any
portion of or all of the Collateral or the possession thereof by any purchaser
at any sale under this Security Agreement, and each Grantor, for itself and all
who may claim under each Grantor, as far as each Grantor now or hereafter
lawfully may do so, hereby waives the benefit of all such laws.

                SECTION 13. Continuing Security Interest. This Security
Agreement shall create a continuing security interest in the Collateral and
shall (a) remain in full force and effect until the payment and performance in
full of the Secured Obligations, (b) be binding upon each Grantor and its
successors and assigns, and (c) inure to the benefit of the Collateral Agent,
each of the Secured Parties and their respective successors, transferees and
assigns. At any time and from time to time prior to termination of the Security
Interests, the Collateral Agent may release any of the Collateral with the prior
written consent of the Majority Secured Parties; provided, however, that the
Security Interest of the Collateral Agent in any Collateral constituting an
asset of which the Grantors may dispose under the Related Documents shall
automatically terminate and be released upon such disposition by any such
Grantor without the necessity of any further action or consent by the Collateral
Agent or any Secured Party. Upon the payment and performance in full of the
Secured Obligations and termination of all Commitments of the Secured Parties to
extend credit or provide financing, the security interest granted hereby shall
terminate and all rights to the Collateral shall revert to the Grantors. Upon
any such termination, the Collateral Agent will deliver to MiniMed counterpart
No. 1 of the Master Lease and Construction Agency Agreement, the original
executed counterpart of the Parent Guaranty and Subsidiary Guaranty delivered to
it and any amendments or supplements thereto held by the Collateral Agent and
will, at the expense of the Grantors, execute and deliver to the Grantors such
other documents as the Grantor shall reasonably request to evidence such
termination and release of all security interests held for the benefit of the
Secured Parties.

                SECTION 14. Obligations Under the Master Lease, the Construction
Agency Agreement and Subordinated Mortgage. Anything herein contained to the
contrary notwithstanding, (i) the Lessee and Construction Agent, as applicable,
shall remain liable under the Master Lease, the Construction Agency Agreement
and the Subordinated Mortgage to perform all of its obligations and agreements
thereunder, (ii) if an Event of Default shall occur and



                                      -15-
   16

be continuing, the obligations of the Lessee, Construction Agent and Mortgagee,
as applicable, under the Master Lease, the Construction Agency Agreement and the
Subordinated Mortgage may be performed by the Collateral Agent or its nominee or
other assignee of the Collateral Agent without releasing the Lessee,
Construction Agent and Mortgagee, as applicable, therefrom, and (iii) neither
the Collateral Agent nor the Secured Parties shall have any obligation or
liability under the Master Lease, the Construction Agency Agreement or the
Subordinated Mortgage by reason of, or arising out of, this Security Agreement
or be obligated to perform any of the obligations or agreements of the Lessee
and Construction Agent, as applicable, thereunder or to make any payment or to
make any inquiry of the sufficiency of any payment received by the Lessee, the
Construction Agent, the Mortgagee or the Collateral Agent or to present or file
any claim or to take any other action to enforce any right, title or interest
assigned hereunder.

                SECTION 15. Intentionally Omitted.

                SECTION 16. No Action Contrary to Lessee's Rights under the
Master Lease or Lessee's Rights, as agent, under the Construction Agency
Agreement. So long as no Event of Default has occurred and is continuing and
subject respectively to the terms and conditions of the Master Lease and the
Construction Agency Agreement, the Collateral Agent shall not take or cause to
be taken any action contrary to the rights of the Lessee under the Master Lease
and the Construction Agency Agreement; provided, however, that nothing contained
herein shall limit any rights the Secured Parties and the Collateral Agent may
have against the Lessee pursuant to any of the other Related Documents to which
it is a party.

                SECTION 17. GOVERNING LAW AND CONSENT TO JURISDICTION, WAIVER OF
JURY TRIAL, SERVICE OF PROCESS. (a) THIS AGREEMENT HAS BEEN EXECUTED AND
DELIVERED IN THE STATE OF NEW YORK. EACH GRANTOR AGREES THAT, TO THE MAXIMUM
EXTENT PERMITTED BY THE LAWS OF THE STATE OF NEW YORK, THIS AGREEMENT, AND THE
RIGHTS AND DUTIES OF EACH GRANTOR HEREUNDER, SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (INCLUDING, WITHOUT
LIMITATION, SECTIONS 5-1401 AND 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW)
IN ALL RESPECTS, INCLUDING, WITHOUT LIMITATION, IN RESPECT OF ALL MATTERS OF
CONSTRUCTION, VALIDITY AND PERFORMANCE. EACH GRANTOR HEREBY IRREVOCABLY SUBMITS,
FOR ITSELF AND ITS PROPERTIES, TO THE JURISDICTION OF THE UNITED STATES DISTRICT
COURT FOR THE SOUTHERN DISTRICT OF NEW YORK AND THE SUPREME COURT OF THE STATE
OF NEW YORK IN THE COUNTY OF NEW YORK IN ANY ACTION, SUIT OR PROCEEDING BROUGHT
AGAINST IT AND RELATED TO OR IN CONNECTION WITH THIS AGREEMENT, AND TO THE
EXTENT PERMITTED BY APPLICABLE LAW, EACH GRANTOR HEREBY WAIVES AND AGREES NOT TO
ASSERT BY WAY OF MOTION, AS A DEFENSE OR OTHERWISE IN ANY SUCH SUIT, ACTION OR
PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF
SUCH COURT, THAT THE SUIT, ACTION OR



                                      -16-
   17

PROCEEDING, IS BROUGHT IN AN INCONVENIENT FORUM, THAT THE VENUE OF THE SUIT,
ACTION OR PROCEEDING IS IMPROPER, OR THAT THIS AGREEMENT OR THE SUBJECT MATTER
HEREOF MAY NOT BE LITIGATED IN OR BY SUCH COURT. THIS SUBMISSION TO JURISDICTION
IS NONEXCLUSIVE AND DOES NOT PRECLUDE THE COLLATERAL AGENT OR ANY SECURED PARTY
FROM OBTAINING JURISDICTION OVER ANY GRANTOR IN ANY COURT OTHERWISE HAVING
JURISDICTION. TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH GRANTOR AGREES NOT
TO SEEK AND HEREBY WAIVES THE RIGHT TO ANY REVIEW OF THE JUDGMENT OF ANY SUCH
COURT BY ANY COURT OF ANY OTHER NATION OR JURISDICTION WHICH MAY BE CALLED UPON
TO GRANT AN ENFORCEMENT OF SUCH JUDGMENT. EACH GRANTOR AGREES THAT SERVICE OF
PROCESS MAY BE MADE UPON IT BY CERTIFIED OR REGISTERED MAIL TO THE ADDRESS FOR
NOTICES SET FORTH IN THIS AGREEMENT OR ANY METHOD AUTHORIZED BY THE LAWS OF NEW
YORK. EACH GRANTOR EXPRESSLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM RELATED TO THIS AGREEMENT. EACH GRANTOR ACKNOWLEDGES
THAT THE PROVISIONS OF THIS SECTION 17 HAVE BEEN BARGAINED FOR AND THAT THEY
HAVE BEEN REPRESENTED BY COUNSEL IN CONNECTION HEREWITH.

                (b) Each Grantor hereby irrevocably designates, appoints and
empowers CT Corporation System, whose present address is 1633 Broadway, New
York, New York 10019, as its authorized agent to receive, for and on its behalf
and its property, service of process in the State of New York when and as such
legal actions or proceedings may be brought in the courts of the State of New
York or of the United States of America sitting in New York, and such service of
process shall be deemed complete upon the date of delivery thereof to such agent
whether or not such agent gives notice thereof to such Grantor, or upon the
earliest of any other date permitted by applicable law. It is understood that a
copy of said process served on such agent will as soon as practicable be
forwarded to such Grantor, at its address set forth on the signature pages
attached hereto, but its failure to receive such copy shall not affect in any
way the service of said process on said agent as the agent of any such Grantor.
Each Grantor irrevocably consents to the service of process out of any of the
aforementioned courts in any such action or proceeding by the mailing of the
copies thereof by certified mail, return receipt requested, postage prepaid, to
it at its address set forth in Section 19(c), such service to become effective
upon the earlier of (i) the date ten (10) calendar days after such mailing or
(ii) any earlier date permitted by applicable law. Each Grantor agrees that it
will at all times continuously maintain an agent to receive service of process
in the State of New York on behalf of itself and its properties and in the event
that, for any reason, the agent named above or its successor shall no longer
serve as its agent to receive service of process in the State of New York on its
behalf, it shall promptly appoint a successor so to serve and shall advise the
Lessor thereof (and shall furnish to the Lessor the consent of any successor
agent so to act). Nothing in this Section 17(b) shall affect the right of the
Collateral Agent to bring proceedings against any Grantor in the courts of any
other jurisdiction or to serve process in any other manner permitted by
applicable law.



                                      -17-
   18

        SECTION 18. Expenses. In the event that any Grantor fails to comply with
the provisions of any Related Documents, such that the value of any Collateral
or the validity, perfection, rank or value of the Security Interests are thereby
diminished or potentially diminished or put at risk, the Collateral Agent, if
requested by the Majority Secured Parties may, but shall not be required to,
effect such compliance on behalf of such Grantor, and the Grantors shall
reimburse the Collateral Agent, jointly and severally, for the reasonable costs
thereof on demand. All reasonable insurance expenses and all reasonable expenses
of protecting, storing, warehousing, appraising, insuring, handling, maintaining
and shipping the Collateral, any and all excise, stamp, intangibles, transfer,
property, sales, and use taxes imposed by any state, federal, or local authority
or any other governmental authority on any of the Collateral, or in respect of
periodic appraisals and inspections of the Collateral to the extent the same may
be requested by the Majority Secured Parties from time to time, or in respect of
the sale or other disposition thereof, shall be borne and paid by the Grantors;
and if the Grantors fail promptly to pay any portion thereof when due, the
Collateral Agent or such Secured Party may, at its option, but shall not be
required to, pay the same and charge the Grantors' accounts therefor, and the
Grantors agree to reimburse the Collateral Agent or such Secured Party therefor
on demand. All sums so paid or incurred by the Collateral Agent or such Secured
Party for any of the foregoing and any and all other sums for which the Grantors
may become liable hereunder and all reasonable costs and expenses (including
reasonable attorneys' fees, legal expenses and court costs) incurred by the
Collateral Agent or such Secured Party in enforcing or protecting the Security
Interests or any of their rights or remedies thereon shall be payable by the
Grantors on demand and shall bear interest (after as well as before judgment)
until paid at a rate equal to the Base Rate plus an additional 2.00% per annum,
and shall be additional Secured Obligations hereunder.

        SECTION 19. Additional Grantors. In the event that any Subsidiary of
MiniMed is required, under the terms of the Parent Guaranty, the Revolving
Credit Agreement or any other Related Document or otherwise, to become a Grantor
hereunder, such Subsidiary shall so become a Grantor hereunder, and be bound by
all of the terms and conditions hereof, upon delivering to the Collateral Agent
an executed counterpart of a Supplement to Security Agreement in the form of
Exhibit A attached hereto.

        SECTION 20. Miscellaneous.

                (a) Assignment. No Grantor may assign its rights or obligations
under this Agreement except as provided in the Participation Agreement. The
Collateral Agent may assign its rights under this Agreement in accordance with
the provisions of the Participation Agreement, and no such assignment or
delegation shall diminish any Grantor's obligations hereunder.

                (b) Amendments and Waivers. The provisions of this Agreement may
from time to time be amended, modified or waived solely in accordance with the
provisions of the Participation Agreement. No failure of delay on the part of
the Collateral Agent or any Secured Party in exercising any power or right under
this Agreement shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power or right preclude any other or further



                                      -18-
   19
exercise thereof or the exercise of any other power or right.

                (c) Notices. All notices, requests, demands and other
communications to any party hereunder shall be in writing (including telex,
telecopier or similar writing) and shall be given to such party at its address
or telecopier number set forth below or such other address, telex or telecopier
number as such party may hereafter specify by notice to the other parties listed
below. Any notice, request, demand or other communication sent by telex or
telecopier shall be promptly confirmed with a copy of such notice sent by
courier or by first class mail.
