REINSURANCE COMPANY LIMITED ("PARTY A"), PLATINUM RE (UK) LIMITED ("PARTY B"),
AND STATE STREET BANK AND TRUST COMPANY ("CUSTODIAN") (the "AGREEMENT").

         WHEREAS, pursuant to a custodian and investment accounting agreement
between Custodian and various affiliated parties including Party B (as amended,
the "CUSTODIAN AGREEMENT"), Custodian acts as custodian for Party B's assets
and, as such Custodian, has established a custodial account in the name of Party
B in which the Collateral, as defined below (together with other assets of Party
B) is held; and

         WHEREAS, Party A and Party B have entered into a retrocession
agreement, dated as of November __, 2002 (the "RETROCESSION AGREEMENT") and A
security agreement, dated as of November__, 2002 in the form attached hereto as
Exhibit A (the "SECURITY AGREEMENT") pursuant to the terms of which, Party B
will from time to time grant a continuing first priority security interest over
certain assets specified by Party B and identified in writing to Custodian as
Collateral as defined in the Security Agreement (the "COLLATERAL") to secure
Party B's obligations under the Retrocession Agreements; and

         WHEREAS, Party A, Party B and Custodian are entering into this
Agreement for the purpose of appointing Custodian to serve as collateral agent
for Party A and to serve as securities intermediary as herein provided in order
to provide Party A with control of the Collateral Accounts and the Collateral
credited thereto and held therein (each as defined below), in each case for the
purpose of perfecting and establishing the priority of Party A's security
interest in such Collateral;

         NOW, THEREFORE, in consideration of the mutual promises set forth
herein, it is agreed as follows:

1.       APPOINTMENT AND ESTABLISHMENT OF ACCOUNTS.

         1.1      Party A hereby appoints Custodian as collateral agent on its
behalf and Custodian hereby accepts such appointment. In addition, Custodian
agrees to act as securities intermediary and/or depositary bank, as applicable,
with respect to the Collateral Accounts and the Collateral held therein pursuant
hereto.

         1.2      The Custodian has established and will maintain a segregated
account (which may include one or more sub-accounts) entitled "Platinum Re (UK)
Limited for the Benefit of St. Paul Reinsurance Company Limited" (the
"Securities Account"); and a separate and segregated deposit account or accounts
(as defined in Section 9-102 of the UCC) entitled "Platinum Re (UK) Limited for
the Benefit of St. Paul Reinsurance Company Limited" (the "Deposit Account", and
together with the Securities Account, the "COLLATERAL ACCOUNTS"), all as more
particularly described on the attached Schedule I, hereto. Each party hereto
agrees that (i) the Securities Account constitutes a "securities account" within
the meaning of Article 8 of the UCC, and (ii) all property now or hereafter
held, credited or earned by, in or to the credit of Securities

                                       1

<PAGE>

Account (other than "Identified Securities", as defined in Section 5(vi), and
cash) shall be treated as "financial assets" within the meaning of UCC Section
S-102(a)(9). Each of the Collateral Accounts shall be maintained separately and
apart from any other account or sub-account of Party B. The Custodian shall not
change the name of the Collateral Accounts without the prior written consent of
Party A. Except for specified "Identified Securities", as provided hereinafter,
Party B agrees that all financial assets credited to the Collateral Accounts
shall be registered in the name of the Custodian, endorsed to the Custodian or
in blank or credited to another securities account maintained in the name of the
Custodian, and except for such Identified Securities, no financial asset
credited to the Collateral Accounts shall be registered in the name of Party B,
payable to the order of Party B or specially endorsed to Party B except to the
extent the foregoing have been specially endorsed to the Custodian or in blank.

         1.3      The Custodian agrees that it shall promptly notify Party A and
Party B in writing after becoming aware that any financial asset which
constitutes Collateral is registered or endorsed otherwise than as provided in
the foregoing Section 1.2; provided, however, that the Custodian shall have no
liability hereunder for the failure to deliver such notice except to the extent
such failure results from its negligence or misconduct.

         1.4      Party B, from time to time, shall instruct Custodian in
writing by any of the means mutually agreed to between Party B and Custodian
(which shall constitute "Proper Instructions" under the Custodian Agreement), to
segregate and hold in a separate account the Collateral for the benefit of Party
A, whereupon any such Collateral, other than cash Collateral, shall be credited
to and held in the Securities Account, and any such cash Collateral shall be
credited to and held in the Deposit Account. Custodian shall have no
responsibility for determining the adequacy of any Collateral required hereunder
or under the Retrocession Agreement, nor will it assume responsibility for any
calculations related to any Collateral requirements under the Retrocession
Agreement.

         1.5      All Cash Proceeds (as defined in UCC Section 9-102(a)(9)) of
the Collateral received by the Custodian, except for the Distributions (as
defined in the Security Agreement (the "Distributions")), shall be deposited in
the Collateral Accounts and become part of the Collateral.

2.       ACCOUNT CONTROL.

         2.1      Security Interest. This Agreement is intended by Party A and
Party B to grant "control" of the Collateral Accounts to Party A for purposes of
the perfection and priority of Party A's security interest in such Collateral
pursuant to Article 8 and Article 9 of the UCC, and Custodian hereby
acknowledges that it has been advised of Party B's grant to Party A of a
security interest in the Collateral Accounts and the Collateral held therein.
Notwithstanding the foregoing, Custodian makes no representation or warranty
with respect to the creation or enforceability of any security interest in the
Collateral Accounts or the Collateral held therein. Custodian shall promptly and
in the exercise of due care and reasonable commercial standards comply with
"entitlement orders" (as that term is defined in UCC Section 8-102(a)(8)),
including but not limited to a Notice of Exclusive Control substantially in the
form attached hereto as Exhibit B ("NOTICE OF EXCLUSIVE CONTROL"), originated by
Party A and concerning the Collateral, without the further consent of Party B,
including without limitation any entitlement order originated by Party A
instructing the Custodian to deliver any or all of the Collateral to Party A

                                       2

<PAGE>

or its designees.

         2.2      Control by Party B. Unless and except to the extent it has
received a contrary entitlement order from Party A pursuant to Section 2.1, and
except as provided in Section 2.3(i), below: (i) Custodian shall take actions
with respect to the Collateral in the Collateral Accounts upon the instructions
of Party B, and (ii) Custodian shall have no responsibility or liability to
Party A or Party B for actions taken in accordance with such instructions. All
entitlement orders and other instructions and communications that Party B is
entitled, or desires, to give or make under this Agreement may be given or made
either by Party B itself or its investment advisor as designated in writing by
Party B to the Custodian from time to time.

         2.3      Control by Party A.

         (i)      Party A agrees to provide Custodian, in the form of Exhibit C
attached (as may be amended from time to time), the names and signatures of
authorized parties who may give notices, instructions, or entitlement orders
concerning the Collateral Accounts and the Collateral held therein. All
entitlement orders and other instructions and communications that Party A is
entitled, or desires, to give or make under this Agreement may be given or made
either by Party A itself or its attorney in fact, as designated in writing by
Party A to the Custodian from time to time. Other means of notice, instruction,
or entitlement orders may be used provided that Party A and Custodian agree to
appropriate security procedures. Upon receipt by Custodian of a Notice of
Exclusive Control, and unless and until such Notice of Exclusive Control has
been revoked in writing by Party A, Custodian shall thereafter follow only the
instructions of Party A with respect to the Collateral Accounts and shall comply
with any entitlement order or instructions (within the meaning of Sections
8-102, 9-104, and 9-106 of the UCC) received from Party A, without further
consent of Party B or any other person, and Custodian will not comply with
entitlement orders or instructions concerning the Collateral originated by Party
B without the prior written consent of Party A.

         (ii)     Party A represents and warrants to Party B that Party A .will
only issue to Custodian a Notice of Exclusive Control if Party A has determined
in good faith that an event has occurred which entitles Party A to exercise its
rights as a secured parry with respect to the Collateral in the Collateral
Accounts.

         (iii)    Custodian shall have no responsibility or liability to Party B
for complying with a Notice of Exclusive Control or complying with entitlement
orders or instructions originated by Party A concerning the Collateral Accounts
and the Collateral held therein. Custodian shall have no duty to investigate or
make any determination to verify compliance by Party A or Party B with
applicable law. Nor shall Custodian have any duty to verify the occurrence of an
event entitling Party A to exercise its rights as a secured party with respect
to the Collateral in the Collateral Accounts, and Custodian shall be fully
protected in complying with a Notice of Exclusive Control whether or not Party B
may allege that no such event has occurred.

         (iv)     As between Party A and Custodian, notwithstanding any
provision contained herein or in any other document or instrument to the
contrary, Custodian shall not be liable for any action taken or omitted to be
taken at the instruction of Party A, or any action taken or omitted to be taken
under or in connection with this Agreement, except for Custodian's own
negligence or willful misconduct in carrying out such instructions.

                                       3

3.       DISTRIBUTIONS. Custodian shall transfer the Distributions to the Party
B within ten (10) days following the end of each calendar month, upon proper
written instructions by Party B. to Party B's custodial account or any other
account designated by Party B unless Custodian has received a Notice of
Exclusive Control and, if any Notice of Exclusive Control is in effect, until
such Notice of Exclusive Control has been revoked or rescinded in writing by
Party A. The Distributions shall not be considered Collateral.

4.       RELEASE OF COLLATERAL; RELEASE OF SECURITY INTEREST.

         4.1      Release of Collateral. As soon as reasonably practicable after
receiving joint instructions from Party A and Parry B, Custodian will release
Collateral held in the Collateral Accounts in accordance with such instructions.
Notwithstanding the foregoing, Custodian will release Collateral held in the
Collateral Accounts upon receipt from Party B of a Substitution Notice as
defined in the Security Agreement notifying Custodian of Party B's intention to
substitute Qualified Assets as defined in the Security Agreement" and in
accordance with instructions from Party B that comport with such Substitution
Notice, provided, that no contrary instructions have been received from Party A,
and that no Notice of Exclusive Control is then in effect.

         4.2      Release of Security Interest. Party A agrees to notify
Custodian promptly in writing when all obligations of Party B to Party A under
the Retrocession Agreement and the Security Agreement have been fully satisfied
or Party A otherwise no longer claims any interest in the Collateral in the
Collateral Accounts, whichever is sooner; at which time Custodian shall have no
further liabilities or responsibilities hereunder and Custodian's obligations
under this Agreement shall terminate.

5.       DUTIES AND SERVICES OF CUSTODIAN.

         (i)      Custodian agrees that it is acting as a securities
intermediary, as defined in Section 8-102 of the UCC with respect to the
Collateral in the Securities Account, except Identified Securities. Custodian
agrees, with respect to the Deposit Account, that it is acting as a "bank" as
such term is used in Section 9-102(a)(29) of the UCC. The parties hereto,
acknowledge that the Custodian Agreement is governed by the laws of The
Commonwealth of Massachusetts and that, as a consequence, the jurisdiction of
Custodian as securities intermediary and as bank is The Commonwealth of
Massachusetts.

         (ii)     Custodian shall have no duties, obligations, responsibilities
or liabilities with respect to the Collateral Accounts and the Collateral held
therein except as and to the extent expressly set forth in this Agreement and
the Custodian Agreement, and no implied duties of any kind shall be read into
this Agreement against Custodian including, without limitation, the duty to
preserve, exercise or enforce rights in the Collateral and the Collateral
Accounts. Custodian shall not be liable or responsible for anything done or
omitted to be done by it in good faith and in the absence of negligence and may
rely and shall be protected in acting upon any notice, instruction, entitlement
orders, or other communication which it reasonably believes to be genuine and
authorized.

         (iii)    As between Party B and Custodian, except for the rights of
control in favor of Party A agreed to herein, nothing herein shall be deemed to
modify, limit, restrict, amend or supersede the terms of the Custodian
Agreement, and Custodian shall be and remain entitled to all of the rights,
indemnities, powers, and protections in its favor under the Custodian

                                       4

<PAGE>

Agreement, which shall apply fully to Custodian's actions and omissions
hereunder. Instructions under this Agreement from Party B's authorized
representative given in accordance with the terms of the Custodian Agreement
shall also constitute Proper Instructions under the Custodian Agreement.

         (iv)     As between Custodian and Party A, Party A shall indemnify and
hold Custodian harmless with regard to any losses or liabilities of Custodian
(including reasonable attorneys' fees) imposed on or incurred by Custodian
arising out of any action or omission of Custodian in accordance with any
notice, instruction, or entitlement order of Party A under this Agreement except
for actions or omissions due to Custodian's own negligence or willful
misconduct.

         (v)      The parties hereto acknowledge that no "security entitlement"
under the UCC shall exist with respect to any cash or to any financial asset
held in the Collateral Accounts which is registered in the name of Party B,
payable to the order of the Party B, or specially indorsed to Party B or any
third party (each such asset an "IDENTIFIED SECURITY"), except to the extent
such Identified Security has been specially indorsed by Party B to Custodian or
in blank. The parties further acknowledge and agree that any such cash and/or
Identified Securities received by Custodian and credited to the Collateral
Accounts from time to time shall (so long as so credited to the Collateral
Accounts and so long as this Agreement remains in effect) be held by Custodian
for the benefit of and on behalf of Party A, not in its capacity as a
"securities intermediary" (as defined in the UCC), but in its capacity as a
collateral agent under and subject to the terms of this Agreement.

         (vi)     For avoidance of doubt, Party A hereby acknowledges that any
Collateral in the Collateral Accounts issued outside the United States ("FOREIGN
SECURITY SYSTEM ASSETS") which may be held by Custodian, a sub-custodian within
Custodian's network of sub-custodians (each a "SUB-CUSTODIAN") or a depositor}7
or book-entry system for the central handling of securities and other financial
assets in which Custodian or the Sub-Custodian are participants may not permit
Party B to have a security entitlement under the UCC with respect to such
Foreign Security System Assets (and such property shall be deemed for purposes
of this Agreement not to be a financial asset held within the Collateral
Accounts). The parties hereby further acknowledge that Custodian gives no
assurance that a security entitlement is created under the UCC with respect to
Party B's assets held in Euroclear or Clearstream or their successors.

         (vii)    Custodian shall from time to time employ one or more
sub-custodians in accordance with the terms of the Custodian Agreement.

6.       FORCE MAJEURE; SPECIAL DAMAGES. Custodian shall not be liable for
delays, errors or losses occurring by reason of circumstances beyond its control
including, without limitation, acts of God, market disorder, terrorism,
insurrection, war, riots, failure of transportation or equipment, or failure of
vendors, communication or power supply. In no event shall Custodian be liable to
any person for indirect, consequential or special damages, even if Custodian has
been advised of the possibility or likelihood of such damages.

7.       COMPLIANCE WITH LEGAL PROCESS AND JUDICIAL ORDERS. Custodian shall have
no responsibility or liability to Party A or Party B or to any other person or
entity for acting in accordance with any judicial or arbitral process, order,
writ, judgment, decree or claim of lien relating to the Collateral Accounts and
the Collateral held therein subject to this Agreement notwithstanding that such
order or process is subsequently modified, vacated or otherwise

                                       5

<PAGE>

determined to have been without legal force or effect.

8.       CUSTODIAN REPRESENTATIONS. Custodian agrees and confirms, as of the
date hereof, and at all times until the termination of this Agreement, that it
has not entered into, and until the termination of this Agreement will not enter
into, any agreement (other than the Custodian Agreement) with any other person
or entity relating to the Collateral or the Collateral Accounts under which it
has agreed to comply with entitlement orders (as defined in Section 8-102 of the
UCC) of such other person or entity.

9.       ACCESS TO REPORTS. Upon any pledge, release, or substitution of
Collateral in the Collateral Accounts, Custodian shall notify Party A within one
business day of such change. Custodian will provide to Party A a copy of a
statement of the Collateral Accounts and the Collateral held therein within five
(5) business days of the end of the calendar month; provided, however, that
Custodian's failure to forward a copy of such statement to Party A shall not
give rise to any liability hereunder.

10.      INTERPLEADER. Notwithstanding any provision contained in this Agreement
to the contrary, in the event of any dispute concerning this Agreement or the
disposition of any of the Collateral or the Collateral Accounts, Custodian shall
have the absolute right, at its election, to (a) refrain from taking any action
(other than to hold the Collateral in accordance with the Custodian Agreement)
until directed by written instructions signed by Party B and Party A or by final
order of a court of competent jurisdiction; or (b) in the event of litigation
between Party B and Party A, deliver all of the Collateral in the Collateral
Accounts to the clerk of any court in which such litigation is pending, or file
suit in interpleader and deliver the Collateral in the Collateral Accounts to
the court in which the action is commenced, and obtain an order from the court
requiring the parties to interplead and litigate in such court their claims and
rights among themselves, whereupon Custodian shall thereby be relieved from any
further liability respecting the Collateral and the Collateral Accounts.

11.      FEES AND EXPENSES OF CUSTODIAN. In addition to the terms of the
Custodian Agreement, Party B hereby agrees to pay and reimburse Custodian for
any advances, fees, costs, expenses (including, without limitation, reasonable
attorney's fees and costs) and disbursements that may be paid or incurred by
Custodian in connection with this Agreement or the arrangement contemplated
hereby, including any that may be incurred in performing its duties or
responsibilities pursuant to the terms of this Agreement. Any fees, expenses or
other amounts that may be owing to Custodian from time to time pursuant to the
terms hereof, or of the Custodian Agreement shall be secured by any lien,
encumbrance or other right Custodian may have under the Custodian Agreement or
applicable law, and Custodian shall be entitled to exercise its rights and
remedies against the Collateral and Collateral Accounts in accordance with the
terms and conditions of the Custodian Agreement.

It is hereby expressly acknowledged and agreed by the parties that Custodian
(including its agents) shall not be obligated to advance cash or investments to,
for or on behalf of Party B in the Collateral Accounts, provided, however, that
if Custodian does advance cash or investments to the Collateral Accounts for any
purpose (including but not limited to securities settlements, foreign exchange
contracts, assumed settlement or account overdraft) for the benefit of Party B,
any property at any time held pursuant to this Agreement and the Custodian
Agreement shall be security therefor and, should Party B fail to repay Custodian
promptly, Custodian shall be entitled to utilize available cash and to dispose
of Collateral in the Collateral Accounts to the

                                       6

extent necessary to obtain reimbursement.

Asset Value, if any, shall be the "Excess Reserves". To the extent the Ending

proposal for the amount of the reserves described in Section 3.02 hereof. If the

of the Secured Party's indication of disagreement, the parties shall mutually
agree upon an independent actuarial firm to determine an appropriate level of
aggregate reserves as described in Section 3.02 hereof with respect to the
Reinsurance Contracts, such level to be no more than the amount proposed by the
Secured Party and no less than the amount reported by the Debtor, and both
parties agree to be bound by such determination. In such case the Debtor
shall deposit sufficient Qualifying Assets with a fair market value equal to
Excess Reserves (if any) within 3 Local Business Days after receipt of the
actuary report. The fees and expenses of the actuarial firm shall be shared
equally by the Debtor and the. Secured Party.

otherwise agreed between the parties from time to time, if an obligation to
transfer Qualified Assets or Collateral has become due by the Notification
Time, then the relevant transfer will be made not later than the close of
business on the Settlement Day relating to the date such obligation has become
due; if an obligation becomes due after the Notification Time, then the relevant

purpose of this Agreement shall prevail over any valuations performed by or for

Credit Support"') for certain Qualified Assets specified in the Substitution
Notice and held in the Collateral Accounts (the "Original Credit Support").

                  (b)      Following the service of such Substitution Notice,

                  Section 5.03 No Liens. The Debtor is the owner of all
Collateral free from any Lien or other right, title or interest of any Person
(other than the Custodian Lien), and the Debtor shall defend such Collateral
against all claims and demands of all Persons at any time claiming the same or
any interest therein adverse to the Secured Party.

                  Section 5.04 Other Financing Statements. There is no financing
statement (or similar statement or instrument of registration under the law of
any jurisdiction) covering or purporting to cover any interest of any kind in
the Collateral, and so long as any of the Obligations remain unpaid, the Debtor
will not execute or authorize to be filed in any public office any financing
statement (or similar statement or instrument of registration under the law of
any jurisdiction.) or statements relating to the Collateral, except financing
statements filed or to be filed in respect of and covering the security
interests granted hereby.

                  Section 5.05 Consents. No consent of any Person and no
authorization, approval or other action by, and no notice to or filing with, any
Governmental Authority of any jurisdiction is required as of the date of the
execution and delivery of this Agreement for (i) the grant by the Debtor of the
pledge, assignment and security interest granted hereby with respect to the
Collateral, (ii) the execution, delivery or performance of this Agreement by the
Debtor, (iii) the pledge, assignment and security interest created hereby
with respect to the Collateral (including the first priority nature of such
pledge, assignment and security interest with respect to the Collateral (subject
to the Control Agreement and filing of Custodian Lien)) other than the execution
and delivery of the g of appropriate financing statements or similar filings or
notifications in respect of the Collateral or (iv) the exercise by the Secured
Party of the rights provided for in this Agreement or the remedies in respect of
the Collateral pursuant to this Agreement.

                  (b)      The Debtor shall use its best efforts to obtain after
the date of the execution and delivery of this Agreement such other consents,
authorizations, and approvals and obtain such other actions by, and provide such
notices to or make such filings with, any Governmental Authority of any
jurisdiction as may be, in the reasonable judgment of the Secured Party,
necessary after the date of this Agreement (i) for the grant by the Debtor of
the pledge, assignment and security interest granted hereby or for the
execution, delivery or performance of this Agreement by the Debtor, (ii) for the
pledge, assignment and security interest created hereby with respect to the
Collateral (including the first priority nature of such pledge, assignment and
security interest with respect to the Collateral (subject to the Custodian
Lien)) or (iii) for the exercise by the Secured Party of the rights, remedies
and powers provided for in this Agreement or the remedies in respect of the
Collateral pursuant to this Agreement.

                  Section 5.06 Further Actions. The Debtor will, at its own
expense, make, execute, endorse, acknowledge, or otherwise authenticate and file
and/or deliver to the Secured Party from time to time such confirmatory
assignments, conveyances, financing statements, transfer endorsements, powers of
attorney, certificates and other assurances, instruments or other records, and
take such further steps relating to the Collateral and other property or rights
covered by the interests hereby granted, which the Secured Party, upon written
direction, deems reasonably appropriate or advisable to perfect, preserve or
protect its security interests in the Collateral.

                  Section 5.07 Financing Statements. The Debtor agrees to
execute or otherwise authenticate (if necessary) and deliver to the Secured
Party such financing statements (or similar statement or instrument of
registration under the Jaw of any jurisdiction), in form acceptable to the
Secured Party as it may from time to time reasonably request or as are necessary
or desirable in its reasonable opinion to establish and maintain the security
interests contemplated hereunder as valid, enforceable and first priority
security interests (subject to the Custodian Lien) as provided herein and the
other rights and security contemplated herein, all in accordance with the UCC as
enacted in any and all relevant jurisdictions or any other Requirement of Law.
The Debtor will pay any applicable filing fees and related expenses. The Debtor
authorizes the Secured Party to file any such financing statements without the
signature of the Debtor.

                                   ARTICLE VI

                   REMEDIES UPON OCCURRENCE OF RELEVANT EVENT

                  Section 6.01 Remedies: Obtaining and Disposition of the
Collateral Upon Default. The Debtor agrees that, if any Relevant Event has
occurred and is continuing, then and in every such case, subject to any
Requirements of Law, the Secured Party may:

                  (a)      deliver a Notice of Exclusive Control, instructions
or entitlement orders with respect to the Collateral Accounts or the Collateral;

                  (b)      exercise in respect of the Collateral, in addition to
other rights and remedies provided for herein or otherwise available to it. all
the rights and remedies of a secured party upon default under the UCC to enforce
this Agreement and the security interest contained herein, and also may (A) if
applicable, require the Debtor to, and the Debtor hereby agrees that it will at
its expense and upon request of the Secured Party forthwith, assemble all or
part of the Collateral as directed by the Secured Party and make it available to
the Secured Party at a place to be designated by the Secured Party that is
reasonably convenient to both parties, or (B) without notice except as specified
below, sell the Collateral or any part thereof in one or more parcels at public
or private sale, at any of the Secured Party's offices or elsewhere, for cash,
on credit or for future deliver}', and upon such other terms as the Secured
Party may deem commercially reasonable. The Debtor agrees that, to the extent
notice of sale shall be required by law, at least thirty (30) days' notice to
the Debtor of the time and place of any public sale or the time after which any
private sale is to be made shall constitute reasonable notification. The Secured
Party shall not be obligated to make any sale of Collateral regardless of notice
of sale having been given. The Secured Party may adjourn any public or private
sale from time to time

                                       12

<PAGE>

by announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned;

                  (c)      hold any money held by the Secured Party as
Collateral and all cash proceeds received by the Secured Party in respect of any
sale of collection from, or other realization upon all or any part of the
Collateral, as collateral for, and/or, then, or at any time thereafter, apply
such amounts, in whole or in part, against all or any pan of the Obligations,
and to make any currency conversions or effect any transaction in currencies
which it thinks fit, and to do so at such times and rates as it thinks proper;
and

                  (d)      exercise any and all rights and remedies of the
Debtor under or in respect of the Collateral.

                  Section 6.02 Waiver of Claims. Except as otherwise provided in
this Agreement, the Debtor hereby waives, to the extent permitted by all
Requirements of Law:

                  (a)      all damages occasioned by taking of possession except
any damages which are the direct result of the gross negligence or willful
misconduct of the Secured Party or any Person acting on its behalf or
instruction;

                  (b)      all other requirements as to the time, place and
terms of sale or other requirements with respect to the enforcement of the
Secured Party's rights hereunder; and

                  (c)      all rights of redemption, appraisement, valuation,
stay, extension or moratorium now or hereafter in force under any Requirement of
Law in order to prevent or delay the enforcement of this Agreement (including,
without limitation, any right to claim that such enforcement should be stayed
pending the outcome of any other action or proceeding (including any arbitration
proceeding)) or the absolute sale of the Collateral or any portion thereof, and
the Debtor, for itself and all who may claim under it, insofar as it or the}'
now or hereafter lawfully may, hereby waives the benefit of all such
Requirements of Law.

                  Any sale of, or the grant of options to purchase, or any other
realization upon, any Collateral shall operate to divest all right, title,
interest, claim and demand, either at law or in equity, of the Debtor therein
and thereto, and shall be a perpetual bar both at law and in equity against the
Debtor and against any and all Persons claiming or attempting to claim the
Collateral so sold, optioned or realized upon, or any part thereof from, through
and under the Debtor.

                  Section 6.03 Deficiencies and Excess Proceeds. The Secured
Party shall transfer, or cause to be transferred, to the Debtor any proceeds and
Collateral remaining after exercising remedies under Section 6.01 and after
satisfaction in full of all amounts payable by the Debtor with respect to any
Obligations. For the avoidance of doubt, it is understood that the Debtor shall
remain liable to the extent of any deficiency between the amount of the proceeds
of the Collateral and the aggregate amount of the Obligations.

                  Section 6.04 Remedies Cumulative. No failure or delay on the
part of the Secured Party, in exercising any right, power or privilege hereunder
and no course of dealing between the Debtor and the Secured Party shall operate
as a waiver hereof: nor shall any single or partial exercise of any right, power
or privilege hereunder preclude any other or further

                                       13

<PAGE>

exercise hereof or the exercise of any other right, power or privilege
hereunder. The rights, powers and remedies herein expressly provided are
cumulative and not exclusive of any rights, powers or remedies which the Secured
Party would otherwise have. No notice to or demand on the Debtor in any case
shall entitle the Debtor to any other or further notice or demand in similar or
other circumstances or constitute a waiver of the rights of the Secured Party to
any other or further action in any circumstances without notice or demand.

                  Section 6.05 Discontinuance of Proceedings. In case the
Secured Party shall have instituted any proceeding to enforce any right, power
or remedy under this Agreement by foreclosure, sale, entry or otherwise, and
such proceeding shall have been discontinued or abandoned for any reason or
shall have been determined adversely to the Secured Party, then and in every
such case the Debtor, the Secured Party shall be restored to their former
positions and rights hereunder with respect to the Collateral subject to the
security interest created under this Agreement, and all rights, remedies and
powers of the Secured Party shall continue as if no such proceeding had been
instituted.

                                   ARTICLE VII

                                  MISCELLANEOUS

                  (a)      Except as otherwise provided in this Section 7.01 (b)
and 7.01(c), each party will pay its own costs and expenses (including any
stamp, transfer or similar transaction tax or duty payable on any transfer it is
required to make under this Agreement) in connection with performing its
obligations under this Agreement and neither party will be liable for any such
costs and expenses incurred by the other party.

                  (b)      The Debtor shall promptly pay when due all taxes,
assessments or charges of any nature that are imposed with respect to Collateral

                  (c)      All reasonable costs, expenses, charges and fees paid
or incurred by the Secured Party in the exercise of any of the rights, remedies
or powers granted hereunder shall be for the account of the Debtor, and the
Debtor undertakes promptly on demand to pay the same or. as the case may be, to
reimburse the Secured Party and/or its agents, representatives, successors and
assigns as the case may be, for any monies paid by it with interest thereon to
the extent that there are then insufficient funds available in the Collateral
Accounts for this purpose.
