evidenced thereby from the Pledge, the Securities Intermediary shall use its
best efforts to obtain physical possession of a replacement certificate
evidencing any Collateral remaining subject to the Pledge hereunder registered
to it or endorsed in blank within fifteen days of the date it relinquished
possession. The Securities Intermediary shall promptly notify the Company and
the Collateral Agent of the Securities Intermediary's failure to obtain
possession of any such replacement certificate as required hereby.

                  Section 2.2. Control and Perfection.

                  (a) In connection with the Pledge granted in Section 2.1, and
subject to the other provisions of this Agreement, the Holders from time to time
acting through the Purchase Contract Agent, as their attorney-in-fact, hereby
authorize and direct the Securities Intermediary (without the necessity of
obtaining the further consent of the Purchase Contract Agent or any of the
Holders), and the Securities Intermediary agrees, to comply with and follow any
instructions and "entitlement orders" (as defined in Section 8-102(a)(8) of the
Code) that the Company or the Collateral Agent may deliver with respect to the
Collateral Account, the Collateral credited thereto and any Security
Entitlements with respect to financial assets maintained in the Collateral
Account. In the event the Securities Intermediary receives from the Holders or
the Purchase Contract Agent entitlement orders which conflict with entitlement
orders received from the Company or the Collateral Agent, the Securities
Intermediary shall follow the entitlement orders received from the Collateral
Agent. Such instructions and entitlement orders may, without limitation, direct
the Securities Intermediary to transfer, redeem, assign, or otherwise dispose of

Common Stock, Merger Consideration and any Security Entitlements with respect

derived therefrom to the Company. The Purchase Contract Agent and the Holders
from time to time acting through the Purchase Contract Agent, each hereby
further authorize and direct the Company or the Collateral Agent, as agent of
the Company, to itself issue instructions and entitlement orders, and to
otherwise take action, with respect to the Collateral Account, the Collateral
credited thereto and any Security Entitlements with respect thereto, pursuant to
the terms and provisions hereof, all without the necessity of obtaining the
further consent of the Purchase Contract Agent or any of the Holders. The
Collateral Agent shall be the agent of the Company only and shall not be the
agent of the Holders or the Purchase Contract Agent and shall act only in
accordance with the terms hereof or as otherwise directed by the Company.
Without limiting the generality of the foregoing, the Collateral Agent shall
issue entitlement orders to the Securities Intermediary when and as required by
the terms hereof or as otherwise directed by the Company.

                  (b) The Securities Intermediary and the Purchase Contract
Agent, for itself and as agent and attorney-in-fact for the Holders, hereby
confirm and agree that:

         name of the Securities Intermediary, or its nominee, indorsed to the
         Securities Intermediary, or its nominee, or in blank or credited to
         another collateral account maintained in the name of the Securities
         Intermediary and in no case will any financial asset credited to the
         Collateral Account be registered in the name of the Purchase Contract
         Agent or any Holder, payable to the order of, or specially indorsed to,

         Consideration) will be promptly credited to the Collateral Account;

                (iii) the Collateral Account is an account to which financial
         assets are or may be credited, and the Securities Intermediary shall,
         subject to the terms of this Agreement, treat the Purchase Contract
         Agent as the "entitlement holder" (as defined in Section 8-102(a)(7) of
         the Code) with respect to the Collateral Account;

                 (iv) the Securities Intermediary has not entered into, and
         until the termination of this Agreement will not enter into, any
         agreement with any other Person relating to the Collateral Account
         and/or any financial assets credited thereto pursuant to which it has
         agreed to comply with entitlement orders of such other Person; and

                 (v) the Securities Intermediary has not entered into, and until
         the termination of this Agreement will not enter into, any agreement
         with the Company, the Collateral Agent, the Purchase Contract Agent or
         the Holders of the Securities purporting to limit or

                                        6

         condition the obligation of the Securities Intermediary to comply with
         entitlement orders as set forth in this Section 2.2 hereof.

                  (c) The Securities Intermediary and the Purchase Contract
Agent, for itself and as agent and attorney-in-fact for the Holders, hereby
agree that each item of property (whether investment property, financial asset,
security, instrument, cash or otherwise) credited to the Collateral Account,
including any Treasury Strips, Fixed-Share Rights and Common Stock, shall be
treated as a "financial asset" within the meaning of Section 8-102(a)(9) of the
Code.

                  (d) In the event of any conflict between this Agreement (or
any portion hereof) and any other agreement now existing or hereafter entered
into, the terms of this Agreement shall prevail.

                  (e) The Purchase Contract Agent hereby irrevocably constitutes
and appoints the Collateral Agent and the Company, and each of them severally,
with full power of substitution, as the Purchase Contract Agent's
attorney-in-fact to take on behalf of, and in the name, place and stead of, the
Purchase Contract Agent and the Holders, any action necessary or desirable to
perfect and to keep perfected the security interest in the Collateral referred
to in Section 2.1. The grant of such power-of-attorney shall not be deemed to
require of the Collateral Agent any specific duties or obligations not otherwise
assumed by the Collateral Agent hereunder. Notwithstanding the foregoing, in no
event shall the Collateral Agent or Securities Intermediary be responsible for
the preparation or filing of any financing or continuation statements in the
appropriate jurisdictions or responsible for maintenance or perfection (other
than by control) of any Security Interest hereunder. The Collateral Agent agrees
to file such financing statements and amendments thereto as the Company may
direct from time to time.

                  (f) The Purchase Contract Agent represents and warrants that
its chief executive office is located in Columbus, Ohio and that it has more
than one place of business.

                           Distributions on Collateral

                  Section 3.1. Distributions. (a) So long as the Purchase
Contract Agent is the registered owner of the Pledged Ownership Interest in the
Treasury Strips, the Pledged Fixed-Share Right, the Pledged Common Stock or any
securities forming a part of the Pledged Merger Consideration, it shall receive
all payments thereon. If the Pledged Ownership Interest in the Treasury Strips,
the Pledged Fixed-Share Right, the Pledged Common Stock or any securities
forming a part of Pledged Merger Consideration are reregistered, such that the
Collateral Agent becomes the registered holder, all payments and other
distributions thereon including payments of the principal of the Pledged
Ownership Interest in the Treasury Strips and payments or other distributions on
the Pledged Fixed-Share Rights or the Pledged Common Stock or any securities
forming a part of the Pledged Merger Consideration, that are received by the
Collateral Agent and that are properly payable or deliverable hereunder, shall
be:

                  (i) In the case of (A) payments or other distributions on the
         Pledged Fixed-Share Right or the Pledged Common Stock or any securities
         forming a part of Pledged Merger

         Consideration and (B) any payment of the Ownership Interest in the
         Treasury Strips with respect to any Ownership Interest in the Treasury
         Strips that has been released from the Pledge pursuant to Section 4.3
         hereof, shall be paid by wire transfer in same day funds, or delivered,
         by the Collateral Agent to the Purchase Contract Agent, for the benefit
         of the Holders of the applicable Securities, to the account designated
         by the Purchase Contract Agent for such purpose no later than 11:00
         a.m., New York City time, on the Business Day such payment or other
         distribution is received by the Collateral Agent (provided that in the
         event such payment or other distribution is received by the Collateral
         Agent on a day that is not a Business Day or after 9:00 a.m., New York
         City time, on a Business Day, then such payment or delivery shall be
         made no later than 9:30 a.m., New York City time, on the next
         succeeding Business Day); and

                 (ii) In the case of payments in respect of any Pledged
         Ownership Interest in the Treasury Strips to be paid upon settlement of
         such Holder's obligations to purchase Common Stock under the
         Fixed-Share Purchase Contract, paid by wire transfer in same day funds
         to the Company on the Fixed-Share Stock Purchase Date in accordance
         with the procedure set forth in Section 4.5 hereof, in full
         satisfaction of the respective corresponding obligations of the Holders
         under the related Fixed-Share Purchase Contracts.

                  (b) Upon declaration of a dividend or any other distribution
with respect to the Pledged Common Stock, the Company will prepare and transmit
to the Collateral Agent, no later than two Business Days after the date of such
declaration, a Company Certificate setting forth (i) the type and amount of
distribution, (ii) the record date established by the Company for such
distribution and (iii) the date that such distribution will be made to holders
of Common Stock.

                  Section 3.2. Application of Payments. All payments or other
distributions received by the Purchase Contract Agent as provided herein shall
be applied by the Purchase Contract Agent pursuant to the provisions of the
Purchase Contract Agreement. If, notwithstanding the foregoing, (i) the Purchase
Contract Agent or a Holder of a SPACES or Separate PACES shall receive any
payments of principal on account of any Ownership Interest in the Treasury Strip
that, at the time of such payment, is a Pledged Ownership Interest in the
Treasury Strip, the Purchase Contract Agent or such Holder shall hold the same
as trustee of an express trust for the benefit of the Company (and promptly
deliver the same over to the Company) for application to the obligations of
Holders under the related Fixed-Share Purchase Contracts, and Holders shall
acquire no right, title or interest in any such payments of principal so
received or (ii) a Holder of a SPACES shall receive any shares of Common Stock
on account of any Fixed-Share Right that, at the time of receipt of such shares,
is a Pledged Fixed-Share Right, such Holder shall hold the same for the benefit
of the Company and shall promptly deliver the same over to the Purchase Contract
Agent, who shall, as attorney-in-fact for such Holder, in accordance with the
terms hereof and of the Purchase Contract Agreement, pledge and grant to the
Collateral Agent, for the benefit of the Company, as collateral security for the
performance when due by such Holder of its obligations under the related
Variable-Share Repurchase Contract, a security interest in all of the right,
title and interest of the Purchase Contract Agent and such Holder in such Common
Stock.

          Substitution, Release, Repledge and Settlement of Securities

                  Section 4.1. Collateral Substitution and the Splitting Apart
of SPACES. At any time on or prior to the third Business Day immediately
preceding the Fixed-Share Stock Purchase Date, a Holder of SPACES shall have the
right to separate the PACES and the related Variable-Share Repurchase Contract
by substituting a number of shares of Common Stock equal to the Maximum
Variable-Share Settlement Rate per Variable-Share Repurchase Contract (subject
to adjustment under Section 5.6 of the Purchase Contract Agreement), rounded up
to the nearest whole share, for the Pledged Fixed-Share Rights securing such
Holder's obligations under the Variable-Share Repurchase Contracts comprising a
part of such SPACES by (a) Transferring to the Collateral Agent the applicable
number of shares of Common Stock (subject to adjustment) for each Variable-Share
Repurchase Contract being replaced and (b) delivering such SPACES to the
Purchase Contract Agent, accompanied by a notice, substantially in the form of
Exhibit E to the Purchase Contract Agreement, to the Purchase Contract Agent
stating that such Holder has transferred Common Stock to the Collateral Agent
pursuant to clause (a) above and requesting that the Purchase Contract Agent
instruct the Collateral Agent to release from the Pledge the Fixed-Share Rights
related to such SPACES, whereupon the Purchase Contract Agent shall promptly
give such instruction to the Collateral Agent in the form provided in Exhibit D
to the Purchase Contract Agreement. Upon receipt of Common Stock from a Holder
of SPACES and the related instruction from the Purchase Contract Agent, the
Collateral Agent shall release the Fixed-Share Rights and shall promptly
Transfer such Fixed-Share Rights, free and clear of any lien, pledge or security
interest created hereby, to the Purchase Contract Agent. At such point, for each
SPACES that is split apart, the Holder will hold a Separate PACES and Separate
COVERS. All items Transferred and/or substituted by any Holder pursuant to this
Section 4.1, Section 4.2 or any other Section of this Agreement shall be
Transferred and/or substituted free and clear of all liens, claims and
encumbrances.

                  Section 4.2. Collateral Substitution and the Re-Creation of
SPACES. At any time on or prior to the third Business Day immediately preceding
the Fixed-Share Stock Purchase Date, a Holder of Separate PACES and Separate
COVERS shall have the right to recreate SPACES by (a) Transferring to the
Collateral Agent the Fixed-Share Rights then comprising such number of SPACES as
is equal to such Separate COVERS and (b) delivering such Separate PACES and
Separate COVERS to the Purchase Contract Agent, accompanied by a notice,
substantially in the form of Exhibit E to the Purchase Contract Agreement, to
the Purchase Contract Agent stating that such Holder has Transferred the
relevant amount of Fixed-Share Rights to the Collateral Agent pursuant to clause
(a) above and requesting that the Purchase Contract Agent instruct the
Collateral Agent to release from the Pledge the Pledged Common Stock related to
such Separate COVERS, whereupon the Purchase Contract Agent shall promptly give
such instruction to the Collateral Agent in the form provided in Exhibit D to
the Purchase Contract Agreement. Upon receipt of the Fixed-Share Rights from
such Holder and the instruction from the Purchase Contract Agent, the Collateral
Agent shall release the Pledged Common Stock and shall promptly Transfer such
Pledged Common Stock, free and clear of any lien, pledge or security interest
created hereby, to the Purchase Contract Agent.

                  Section 4.3. Termination Event.

                  (a) Upon receipt by the Collateral Agent of written notice
from the Company or written notice from the Purchase Contract Agent that has
been confirmed in writing by the Company that there has occurred a Termination
Event, the Collateral Agent shall release all Collateral from the Pledge and
shall promptly Transfer any Pledged Fixed-Share Rights, Pledged Ownership
Interest in the Treasury Strips, Pledged Common Stock or Pledged Merger
Consideration to the Purchase Contract Agent for the benefit of the Holders of
the Securities, as applicable, free and clear of any lien, pledge or security
interest or other interest created hereby, provided that, if such Termination
Event results from the Company being a debtor under the Bankruptcy Code, the
Collateral Agent shall not release any Collateral except upon receipt of an
opinion, as provided in Section 4.3(b) hereof or as required by final order of
the court with jurisdiction of the Company's case under the Bankruptcy Code.

                  (b) If such Termination Event shall result from the Company
becoming a debtor under the Bankruptcy Code, and if the Collateral Agent shall
for any reason fail promptly to effectuate the release and Transfer of all
Pledged Collateral, as provided by this Section 4.3, the Purchase Contract Agent
shall, in its sole discretion, either:

                  (i) use best efforts to obtain an opinion of a nationally
         recognized law firm reasonably acceptable to the Collateral Agent
         addressed to the Company and the Collateral Agent to the effect that,
         as a result of the Company being the debtor under the Bankruptcy Code,
         the Collateral Agent will not be prohibited from releasing or
         Transferring the Collateral as provided in this Section 4.3, and, if
         such opinion is obtained, shall deliver such opinion to the Collateral
         Agent within ten days after the occurrence of such Termination Event,
         and if (y) the Purchase Contract Agent shall be unable to obtain such
         opinion within ten days after the occurrence of such Termination Event
         or (z) the Collateral Agent shall continue, after delivery of such
         opinion, to refuse to effectuate the release and Transfer of all
         Collateral as provided in this Section 4.3, then the Purchase Contract
         Agent shall within 15 days after the occurrence of such Termination
         Event commence an action or proceeding in the court with jurisdiction
         of the Company's case under the Bankruptcy Code seeking an order
         requiring the Collateral Agent to effectuate the release and Transfer
         of all Pledged Collateral, as provided by this Section 4.3 or

                 (ii) commence an action or proceeding like that described in
         subsection (i)(z) hereof within ten days after the occurrence of such
         Termination Event.

                  Section 4.4. Early Settlement; Merger Early Settlement. Upon
written notice to the Collateral Agent by the Purchase Contract Agent that one
or more Holders of Securities have elected to effect Early Settlement or Merger
Early Settlement of their respective obligations under the Fixed-Share Purchase
Contracts or Variable-Share Repurchase Contracts forming a part of such
Securities in accordance with the terms of the Contracts and the Purchase
Contract Agreement (setting forth the number of such Contracts as to which such
Holders have elected to effect such Early Settlement or Merger Early
Settlement), and that the Purchase Contract Agent has received from such
Holders, and paid or delivered to the Company, as confirmed to the Collateral
Agent in writing by the Company, in the case of the Fixed-Share Purchase
Contracts,

                                       10

<PAGE>

the related Early Settlement Amounts or Merger Early Settlement Amounts, as the
case may be, and in the case of the Variable-Share Repurchase Contracts, Common
Stock as specified in Section 5.9(c) of the Purchase Contract Agreement or
Merger Consideration as specified in Section 5.10(b) of the Purchase Contract
Agreement, as applicable, in each case pursuant to the terms of the Fixed-Share
Purchase Contracts or the Variable-Share Repurchase Contracts, as applicable,
and the Purchase Contract Agreement and that all conditions to such Early
Settlement or Merger Early Settlement, as the case may be, have been satisfied,
then:

                  (i) in the case of a Fixed-Share Purchase Contract, (A) the
         Collateral Agent shall release from the Pledge the Pledged Ownership
         Interest in the Treasury Strip and shall Transfer such Pledged
         Ownership Interest in the Treasury Strip, free and clear of the Pledge
         created hereby, to the Purchase Contract Agent for the benefit of the
         applicable Holders and (B) if the Fixed-Share Purchase Contract being
         settled forms a part of a SPACES, and the related Variable-Share
         Repurchase Contract is not also being settled, the Purchase Contract
         Agent, as attorney-in-fact of the Holder of such Fixed-Share Purchase
         Contract, shall Pledge to the Collateral Agent, out of the shares of
         Common Stock deposited with the Purchase Contract Agent for the benefit
         of such Holder in connection with Early Settlement or Merger Early
         Settlement (subject to Section 5.9(j) of the Purchase Contract
         Agreement), a number of shares of Common Stock equal to the Maximum
         Variable-Share Settlement Rate (subject to adjustment under Section 5.6
         of the Purchase Contract Agreement), rounded up to the nearest whole
         share, in order to secure such Holder's obligation to sell Common Stock
         under the related Variable-Share Repurchase Contract; and

                 (ii) in the case of a Variable-Share Repurchase Contract, the
         Collateral Agent shall release from the Pledge, (A) if the
         Variable-Share Repurchase Contract is held as a component of SPACES,
         the Fixed-Share Right, and (B) if the Variable-Share Repurchase
         Contract is held as a component of a Separate COVERS, the Pledged
         Common Stock, and shall Transfer such Pledged Fixed-Share Rights or
         Pledged Common Stock, as applicable, to the Purchase Contract Agent for
         the benefit of the applicable Holders (subject to the terms of the
         Purchase Contract Agreement).

                  Section 4.5. Application of Proceeds; Collateral
Insufficiency. (a) In the event a Holder has not made an Early Settlement or a
Merger Early Settlement of the Fixed-Share Purchase Contracts underlying its
Securities prior to the Fixed-Share Stock Purchase Date, such Holder shall be
deemed to have elected to pay for the shares of Common Stock to be issued under
such Fixed-Share Purchase Contracts from the proceeds received in respect of the
related Pledged Ownership Interests in the Ownership Interest in the maturing
Treasury Strips. Without receiving any instruction from any such Holder, the
Collateral Agent shall apply such proceeds to the settlement of such Fixed-Share
Purchase Contracts on the Fixed-Share Stock Purchase Date.

                  (b) In the event a Holder has not made an Early Settlement or
a Merger Early Settlement of the Variable-Share Repurchase Contracts underlying
its securities prior to the Variable-Share Stock Purchase Date, such Holder
shall be deemed to have elected to satisfy its delivery obligations thereunder
with the Pledged Common Stock or the Pledged Merger Consideration, as
applicable. Without receiving any instruction from any such Holder, the

                                       11

<PAGE>

Collateral Agent shall apply such Pledged Common Stock or Pledged Merger
Consideration to the settlement of such Variable-Share Repurchase Contract on
the Variable-Share Stock Purchase Date. Upon receipt of an Issuer Order, the
Collateral Agent shall be authorized to dispose of any Pledged Common Stock or
any securities forming a part of Pledged Merger Consideration to the extent
necessary to make a cash payment in respect of a fractional share. Any Pledged
Common Stock or Pledged Merger Consideration in excess of the product of (y) a
number of shares of Common Stock (or equivalent Merger Consideration) equal to
the Variable-Share Settlement Rate times (z) the number of Variable-Share
Repurchase Contracts being settled, and any excess cash resulting from the
disposition by the Collateral Agent of Collateral in order to make a cash
payment in respect of a fractional share, shall be delivered by the Collateral
Agent to the Purchase Contract Agent for the benefit of the Holders of such
Variable-Share Repurchase Contracts.

                  (c) Notwithstanding anything herein to the contrary, if an
event occurs that requires the Settlement Rates to be adjusted pursuant to
Section 5.6 of the Purchase Contract Agreement, no Proceeds with respect to
Collateral received in connection with such an event shall be distributed to the
Purchase Contract Agent for the benefit of the Holders, and all such Proceeds
shall be held by the Collateral Agent as Collateral, until such time as the
Company determines, in accordance with this Section 4.5(c), that a Collateral
Insufficiency (as defined below) does not exist or has been cured. Upon the
occurrence of such an event, the Company shall forthwith determine, in
consultation with the Collateral Agent, whether the Collateral then securing
Separate COVERS is still sufficient to satisfy in full a Holder's delivery
obligations thereunder (an insufficiency of Collateral being referred to as a
"Collateral Insufficiency"). The Company shall specify in the Company
Certificate deliverable to the Collateral Agent and the Purchase Contract Agent
pursuant to Section 5.7(a)(i) of the Purchase Contract Agreement whether a
Collateral Insufficiency exists. The Collateral Agent shall forthwith send to
each applicable Holder a notice, substantially in the form of Exhibit A hereto
(a "Collateral Insufficiency Notice"), requesting that such Holder cure the
Collateral Insufficiency within five Business Days of receipt of the Collateral
Insufficiency Notice by delivering to the Purchase Contract Agent, for Pledge to
the Collateral Agent by the Purchase Contract Agent as attorney-in-fact of such
Holders, additional Common Stock such that, thereafter, the Pledged Common Stock
per Variable-Share Repurchase Contract shall equal the Variable-Share Settlement
Rate or, if in effect prior thereto, the Fixed Variable-Share Settlement Rate,
as adjusted pursuant to Section 5.6 of the Purchase Contract Agreement. If the
Holder does not cure the Collateral Insufficiency within five Business Days of
receiving the Collateral Insufficiency Notice, upon receipt of an Issuer Order
the Collateral Agent shall undertake to sell the Proceeds of the Collateral
received by it in connection with the event triggering the adjustment to the
Settlement Rates, and use the proceeds of such sale to purchase the type and
amount of Collateral necessary to cure the Collateral Insufficiency. If the
Collateral Agent is unable to cure the Collateral Insufficiency as described
above, the Proceeds of the Collateral received in connection with the event
triggering the adjustment to the Settlement Rates shall be retained by the
Collateral Agent as Collateral and, upon settlement of the related
Variable-Share Repurchase Contract, an amount thereof, based on its fair market
value at the time of settlement, equal to the Applicable Market Value of the
Collateral deficiency shall be delivered to the Company on the applicable
Settlement Date. If requested by the Collateral Agent or as otherwise necessary,
a nationally recognized independent investment banking firm shall be retained by
the Company to ascertain the fair market value of such Proceeds at the time of
settlement. If a Holder or the Collateral

                                       12

<PAGE>

Agent cures the Collateral Insufficiency, any Collateral held by the Collateral
Agent in excess of that necessary to fully secure a Holder's delivery
obligations under a Variable-Share Repurchase Contract shall be delivered to the
Purchase Contract Agent for the benefit of such Holder in accordance with the
provisions of this Agreement and the Purchase Contract Agreement. Subject to the
foregoing, the obligations of each Holder of COVERS to deliver Common Stock
pursuant to the underlying Variable-Share Repurchase Contracts are non-recourse
obligations and shall be satisfied solely out of the Collateral pledged to
secure the obligations of such Holders under such Variable-Share Repurchase
Contracts and in no event will such Holders be liable for any deficiency between
such Collateral and the applicable Settlement Rate.

                                    ARTICLE V

                      Voting Rights -- Pledged Common Stock

                  Section 5.1. Exercise by Purchase Contract Agent. The Purchase
Contract Agent may exercise, or refrain from exercising, any and all voting and
other consensual rights pertaining to the Pledged Common Stock or any part
thereof for any purpose not inconsistent with the terms of this Agreement and in
accordance with the terms of the Purchase Contract Agreement; provided, that the
Purchase Contract Agent shall not exercise or, as the case may be, shall not
refrain from exercising such right if, in the judgment of the Company, such
action would impair or otherwise have a material adverse effect on the value of
all or any of the Pledged Common Stock; and provided, further, that the Purchase
Contract Agent shall give the Company and the Collateral Agent at least five
days' prior written notice of the manner in which it intends to exercise, or its
reasons for refraining from exercising, any such right. Upon receipt of any
notices and other communications in respect of any Pledged Common Stock,
including notice of any meeting at which holders of Common Stock are entitled to
vote or solicitation of consents or proxies of holders of Common Stock, the
Collateral Agent shall use reasonable efforts to send promptly to the Purchase
Contract Agent such notice or communication, and as soon as reasonably
practicable after receipt of a written request therefor from the Purchase
Contract Agent, execute and deliver to the Purchase Contract Agent such proxies
and other instruments in respect of such Pledged Common Stock (in form and
substance satisfactory to the Collateral Agent) as are prepared by the Purchase
Contract Agent with respect to the Pledged Common Stock.

                                   ARTICLE VI

                               Rights and Remedies

                  Section 6.1. Rights and Remedies of the Collateral Agent. (a)
In addition to the rights and remedies available at law or in equity, after an
event of default under the Fixed-Share Purchase Contracts or Variable-Share
Repurchase Contracts, the Collateral Agent shall have all of the rights and
remedies with respect to the Collateral of a secured party under the Uniform
Commercial Code (or any successor thereto) as in effect in the State of New York
from time to time (the "Code") (whether or not the Code is in effect in the
jurisdiction where the rights and remedies are asserted) and the TRADES
Regulations and such additional rights and remedies to

                                       13

<PAGE>

which a secured party is entitled under the laws in effect in any jurisdiction
where any rights and remedies hereunder may be asserted. Wherever reference is
made in this Agreement to any section of the Code, such reference shall be
deemed to include a reference to any provision of the Code, which is a successor
to, or amendment of, such section. Without limiting the generality of the
foregoing, such remedies may include, to the extent permitted by applicable law,
(i) retention of the Pledged Collateral in full satisfaction of the Holders'
obligations under the Contracts or (ii) sale of the Collateral in one or more
public or private sales, in each case at the written direction of the Company.

                  (b) Without limiting any rights or powers otherwise granted by
this Agreement to the Collateral Agent, in the event the Collateral Agent is
unable to make payments to the Company on account of any Pledged Ownership
Interest in the Treasury Strip, Pledged Fixed-Share Right, Pledged Common Stock
or Pledged Merger Consideration as provided in Article III hereof in
satisfaction of the obligations of the Holder of the Securities of which such
Pledged Ownership Interest in the Treasury Strip, Pledged Fixed-Share Right,
Pledged Common Stock or Pledged Merger Consideration, as applicable, is a part
under the related Contracts, the inability to make such payments shall
constitute an event of default under the applicable Contracts and the Collateral
Agent shall have and may exercise, with reference to such Pledged Ownership
Interest in the Treasury Strip, Pledged Fixed-Share Right, Pledged Common Stock
or Pledged Merger Consideration, as applicable, and such obligations of such
Holder, any and all of the rights and remedies available to a secured party
under the Code and the TRADES Regulations after default by a debtor, and as
otherwise provided herein or under any other law.

                  (c) Without limiting any rights or powers otherwise granted by
this Agreement to the Collateral Agent, the Collateral Agent is hereby
irrevocably authorized to receive and collect all payments and other
distributions (i) of the principal amount of the Pledged Ownership Interests in
the Treasury Strips, or (ii) on the Pledged Common Stock or the Pledged Merger
Consideration, subject, in each case, to the provisions of Article III, and as
otherwise granted herein.

                  (d) The Purchase Contract Agent, individually and as
attorney-in-fact for each Holder of Securities, agrees that, from time to time,
upon the written request of the Company or the Collateral Agent, such Holder
shall execute and deliver such further documents and do such other acts and
things as the Company or the Collateral Agent may reasonably request in order to
maintain the Pledge, and the perfection and priority thereof, and to confirm the
rights of the Collateral Agent hereunder. The Purchase Contract Agent shall have
no liability to any Holder for executing any documents or taking any such acts
requested by the Company or the Collateral Agent (acting upon the written
request of the Company) hereunder, except for liability for its own grossly
negligent act, its own grossly negligent failure to act, its bad faith or its
own willful misconduct.

                  Section 6.2. Substitutions. Whenever a Holder has the right to
substitute the Fixed-Share Rights or Common Stock, as the case may be, for

a novation of the security interest created hereby.

                    Representations and Warranties; Covenants

                  Section 7.1. Representations and Warranties. The Holders from
time to time, acting through the Purchase Contract Agent as their
attorney-in-fact (it being understood that the Purchase Contract Agent shall not
be liable for any representation or warranty made by or on behalf of a Holder),
hereby represent and warrant to the Collateral Agent, which representations and
warranties shall be deemed repeated on each day a Holder Transfers Collateral
that:

                  (a) such Holder has the power to grant a security interest in
and lien on the Collateral;

                  (b) such Holder is the sole beneficial owner of the Collateral
and, in the case of Collateral delivered in physical form, is the sole holder of
such Collateral and is the sole beneficial owner of, or has the right to
Transfer, the Collateral it Transfers to the Collateral Agent, free and clear of
any security interest, lien, encumbrance, call, liability to pay money or other
restriction other than the security interest and lien granted under Section 2.1;

                  (c) upon the Transfer of the Collateral to the Collateral
Account, the Collateral Agent, for the benefit of the Company, will have a valid
and perfected first priority security interest therein (assuming that any
central clearing operation or any Intermediary or other entity not within the
control of the Holder involved in the Transfer of the Collateral, including the
Collateral Agent, gives the notices and takes the action required of it
hereunder and under applicable law for perfection of that interest and assuming
the establishment and exercise of control pursuant to Section 2.2); and

                  (d) the execution and performance by the Holder of its
obligations under this Agreement will not result in the creation of any security
interest, lien or other encumbrance on the Collateral other than the security
interest and lien granted under Section 2.1 or violate any provision of any
existing law or regulation applicable to it or of any mortgage, charge, pledge,
indenture, contract or undertaking to which it is a party or which is binding on
it or any of its assets.

                  Section 7.2. Covenants. The Holders from time to time, acting
through the Purchase Contract Agent as their attorney-in-fact (it being
understood that the Purchase Contract Agent shall not be liable for any covenant
made by or on behalf of a Holder), hereby covenant to the Collateral Agent that
for so long as the Collateral remains subject to the Pledge:

                  (a) neither the Purchase Contract Agent nor such Holders will
create or purport to create or allow to subsist any mortgage, charge, lien,
pledge or any other security interest whatsoever over the Collateral or any part
of it other than pursuant to this Agreement; and

                  (b) neither the Purchase Contract Agent nor such Holders will
sell or otherwise dispose (or attempt to dispose) of the Collateral or any part
of it except for the beneficial interest therein, subject to the pledge
hereunder, transferred in connection with the Transfer of the Securities.

                  Section 8.1. Appointment, Powers and Immunities. (a) The
Collateral Agent, Custodial Agent, and Securities Intermediary shall each act as
agent for the Company hereunder with such powers as are specifically vested in
the Collateral Agent by the terms of this Agreement, together with such other
powers as are reasonably incidental thereto. Each of the Collateral Agent, the
Custodial Agent and the Securities Intermediary:

                  (i) shall have no duties or responsibilities except those
         expressly set forth or incorporated in this Agreement and no implied
         covenants or obligations shall be inferred from this Agreement against
         any of them, nor shall any of them be bound by the provisions of any
         agreement by any party hereto beyond the specific or incorporated terms
         hereof;

                 (ii) shall not be responsible for any recitals contained in
         this Agreement, or in any certificate or other document referred to or
         provided for in, or received by it under, this Agreement, the
         Securities or the Purchase Contract Agreement (except as specifically
         incorporated by reference herein), or for the value, validity,
         effectiveness, genuineness, enforceability or sufficiency of this
         Agreement (other than as against the Collateral Agent), the Securities
         or the Purchase Contract Agreement or any other document referred to or
         provided for herein (except as specifically incorporated by reference
         herein) or therein or for any failure by the Company or any other
         Person (except the Collateral Agent, the Custodial Agent or the
         Securities Intermediary, as the case may be) to perform any of its
         obligations hereunder or thereunder or for the, priority or, except as
         expressly required hereby, existence, validity, perfection or
         maintenance of any security interest created hereunder;

                (iii) shall not be required to initiate or conduct any
         litigation or collection proceedings hereunder (except in the case of
         the Collateral Agent, pursuant to directions furnished under Section
         8.2, subject to Section 8.6);

                 (iv) shall not be responsible for any action taken or omitted
         to be taken by it hereunder or under any other document or instrument
         referred to or provided for herein or in connection herewith or
         therewith, except for its own gross negligence, bad faith or willful
         misconduct; and

                 (v) shall not be required to advise any party as to selling or
         retaining, or taking or refraining from taking any action with respect
         to, the Securities or other property deposited hereunder.

Subject to the foregoing, during the term of this Agreement, the Collateral
Agent, Custodial Agent, and Securities Intermediary shall take all reasonable
action in connection with the safekeeping and preservation of the Collateral
hereunder.

                  (b) No provision of this Agreement shall require the
Collateral Agent, the Custodial Agent or the Securities Intermediary to expend
or risk its own funds or otherwise incur

                                       16

<PAGE>

any financial liability in the performance of any of its duties hereunder. In no
event shall the Collateral Agent, the Custodial Agent or the Securities
Intermediary be liable for any amount in excess of the value of the Collateral,
except for its own gross negligence, bad faith or willful misconduct.

                  Section 8.2. Instructions of the Company. The Company shall
have the right, by one or more instruments in writing executed and delivered to
the Collateral Agent, the Custodial Agent or the Securities Intermediary, as the
case may be, to direct the time, method and place of conducting any proceeding
for the realization of any right or remedy available to the Collateral Agent, or
of exercising any power conferred on the Collateral Agent, the Custodial Agent
or the Securities Intermediary, as the case may be, or to direct the taking or
refraining from taking of any action authorized by this Agreement; provided,
however, that (i) such direction shall not conflict with the provisions of any
law or of this Agreement and (ii) the Collateral Agent shall receive indemnity
satisfactory to it as provided herein. Nothing in this Section 8.2 shall impair
the right of the Collateral Agent in its discretion to take any action or omit
to take any action which it deems proper and which is not inconsistent with such
direction. None of the Collateral Agent, the Custodial Agent or the Securities
Intermediary has any obligation or responsibility to file UCC financing
statements, except as directed by the Company.

                  Section 8.3. Reliance. Each of the Securities Intermediary,
the Custodial Agent and the Collateral Agent shall be entitled conclusively to
rely upon any certification, order, judgment, opinion, notice or other
communication (including, without limitation, any thereof by telephone,
telecopy, telex or facsimile) believed by it to be genuine and correct and to
have been signed or sent by or on behalf of the proper Person or Persons
(without being required to determine the correctness of any fact stated
therein), and upon advice and statements of legal counsel and other experts
selected in good faith by the Collateral Agent, the Custodial Agent or the
Securities Intermediary, as the case may be. As to any matters not expressly
provided for by this Agreement, the Collateral Agent, the Custodial Agent and
the Securities Intermediary shall in all cases be fully protected in acting, or
in refraining from acting, hereunder in accordance with instructions given by
the Company in accordance with this Agreement.

                  Section 8.4. Certain Rights. (a) Whenever in the
administration of the provisions of this Agreement the Collateral Agent, the
Custodial Agent or the Securities Intermediary shall deem it necessary or
desirable that a matter be proved or established prior to taking or suffering
any action to be taken hereunder, such matter (unless other evidence in respect
thereof be herein specifically prescribed) may, in the absence of gross
negligence or bad faith or willful misconduct on the part of the Collateral
Agent, the Custodial Agent or the Securities Intermediary, be deemed to be
conclusively proved and established by a certificate signed by one of the
Company's officers, and delivered to the Collateral Agent, the Custodial Agent
or the Securities Intermediary and such certificate, in the absence of gross
negligence or bad faith or willful misconduct on the part of the Collateral
Agent, the Custodial Agent or the Securities Intermediary, shall be full warrant
to the Collateral Agent, the Custodial Agent or the Securities Intermediary for
any action taken, suffered or omitted by it under the provisions of this
Agreement upon the faith thereof.

                  (b) The Collateral Agent, the Custodial Agent or the
Securities Intermediary shall not be bound to make any investigation into the
facts or matters stated in any resolution,

                                       17

<PAGE>

certificate, statement, instrument, opinion, report, notice, request, consent,
entitlement order, approval or other paper or document.

                 Section 8.5. Merger, Conversion, Consolidation or Succession
to Business. Any corporation into which the Collateral Agent, the Custodial
Agent or the Securities Intermediary may be merged or converted or with which it
may be consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Collateral Agent, the Custodial Agent or the
Securities Intermediary shall be a party, or any corporation succeeding to the
business of the Collateral Agent, the Custodial Agent or the Securities
Intermediary shall be the successor of the Collateral Agent, the Custodial Agent
or the Securities Intermediary hereunder without the execution or filing of any
of paper with any party hereto or any further act on the part of any of the
parties hereto except where an instrument or transfer or assignment is required
by law to effect such succession, anything herein to the contrary
notwithstanding.

                 Section 8.6. Rights in Other Capacities. The Collateral Agent,
the Custodial Agent and the Securities Intermediary and their affiliates may
(without having to account therefor to the Company) accept deposits from, lend
money to, make their investments in and generally engage in any kind of banking,
trust or other business with the Purchase Contract Agent, any other Person
interested herein and any Holder of Securities (and any of their respective
subsidiaries or affiliates) as if it were not acting as the Collateral Agent,
the Custodial Agent or the Securities Intermediary, as the case may be, and the
Collateral Agent, the Custodial Agent, the Securities Intermediary and their
affiliates may accept fees and other consideration from the Purchase Contract
Agent and any Holder of Securities without having to account for the same to the
Company; provided that each of the Securities Intermediary, the Custodial Agent
and the Collateral Agent covenants and agrees with the Company that it shall not
accept, receive or permit there to be created in favor of itself and shall take
no affirmative action to permit there to be created in favor of any other
Person, any security interest, lien or other encumbrance of any kind in or upon
the Collateral other than the lien created by the Pledge.

                 Section 8.7. Non-reliance on Collateral Agent, the Custodial
Agent and Securities Intermediary. None of the Securities Intermediary, the
Custodial Agent or the Collateral Agent shall be required to keep itself
informed as to the performance or observance by the Purchase Contract Agent or
any Holder of Securities of this Agreement, the Purchase Contract Agreement, the
Securities or any other document referred to or provided for herein or therein
or to inspect the properties or books of the Purchase Contract Agent or any
Holder of Securities. None of the Collateral Agent, the Custodial Agent or the
Securities Intermediary shall have any duty or responsibility to provide the
Company with any credit or other information concerning the affairs, financial
condition or business of the Purchase Contract Agent or any Holder of Securities
(or any of their respective affiliates) that may come into the possession of the
Collateral Agent, the Custodial Agent or the Securities Intermediary or any of
their respective affiliates.

                 Section 8.8. Compensation and Indemnity. The Company agrees to:

                 (a) pay the Collateral Agent, the Custodial Agent and the
Securities Intermediary from time to time such compensation as shall be agreed
in writing between the Company and the

                                       18

<PAGE>

Collateral Agent, the Custodial Agent or the Securities Intermediary, as the
case may be, for all services rendered by them hereunder;

                  (b) indemnify and hold harmless the Collateral Agent, the
Custodial Agent, the Securities Intermediary and each of their respective
directors, officers, agents and employees (collectively, the "Indemnitees"),
from and against any and all claims, liabilities, losses, damages, fines,
penalties and expenses (including reasonable fees and expenses of counsel)
(collectively, "Losses" and individually, a "Loss") that may be imposed on,
incurred by, or asserted against, the Indemnitees or any of them for following
any instructions or other directions upon which either the Collateral Agent, the
Custodial Agent or the Securities Intermediary is entitled to rely pursuant to
the terms of this Agreement, provided that the Collateral Agent, the Custodial
Agent or the Securities Intermediary has not acted with gross negligence or
engaged in wilful misconduct or bad faith with respect to the specific Loss
against which indemnification is sought; and

                  (c) in addition to and not in limitation of paragraph (b)
immediately above, indemnify and hold the Indemnitees and each of them harmless
from and against, any and all Losses that may be imposed on, incurred by or
asserted against, the Indemnitees or any of them in connection with or arising
out of the Collateral Agent's, the Custodial Agent's or the Securities
Intermediary's acceptance or performance of its powers and duties under this
Agreement, provided the Collateral Agent, the Custodial Agent or the Securities
Intermediary has not acted with gross negligence or engaged in wilful misconduct
or bad faith with respect to the specific Loss against which indemnification is
sought.

                  The provisions of this Section and Section 10.7 shall survive
the resignation or removal of the Collateral Agent, the Custodial Agent or
Securities Intermediary and the termination of this Agreement.

                  Section 8.9. Failure to Act. In the event of any ambiguity in
the provisions of this Agreement or any dispute between or conflicting claims by
or among the parties hereto or any other Person with respect to any funds or
property deposited hereunder, then at its sole option, each of the Collateral
Agent, the Custodial Agent and the Securities Intermediary shall be entitled,
after prompt notice to the Company and the Purchase Contract Agent, to refuse to
comply with any and all claims, demands or instructions with respect to such
property or funds so long as such dispute or conflict shall continue, and the
Collateral Agent, the Custodial Agent and the Securities Intermediary shall not
be or become liable in any way to any of the parties hereto for its failure or
refusal to comply with such conflicting claims, demands or instructions. The
Collateral Agent, the Custodial Agent and the Securities Intermediary shall be
entitled to refuse to act until either:

                  (a) such conflicting or adverse claims or demands shall have
been finally determined by a court of competent jurisdiction or settled by
agreement between the conflicting parties as evidenced in a writing satisfactory
to the Collateral Agent, the Custodial Agent or the Securities Intermediary; or

                  (b) the Collateral Agent, the Custodial Agent or the
Securities Intermediary shall have received security or an indemnity
satisfactory to it sufficient to save it harmless from and

                                       19

<PAGE>

against any and all loss, liability or reasonable out-of-pocket expense which it
may incur by reason of its acting.

                  The Collateral Agent, the Custodial Agent and the Securities
Intermediary may in addition elect to commence an interpleader action or seek
other judicial relief or orders as the Collateral Agent, the Custodial Agent or
the Securities Intermediary may deem necessary. Notwithstanding anything
contained herein to the contrary, none of the Collateral Agent, the Custodial
Agent or the Securities Intermediary shall be required to take any action that
is in its opinion contrary to law or to the terms of this Agreement, or which
would in its opinion subject it or any of its officers, employees or directors
to liability.

                  Section 8.10. Resignation of Collateral Agent, the Custodial
Agent and the Securities Intermediary.

                  (a) Subject to the appointment and acceptance of a successor
Collateral Agent, Custodial Agent or Securities Intermediary as provided below:

                  (i) the Collateral Agent, the Custodial Agent and the
         Securities Intermediary may resign at any time by giving notice thereof
         to the Company and the Purchase Contract Agent as attorney-in-fact for
         the Holders of Securities;

                 (ii) the Collateral Agent, the Custodial Agent and the
         Securities Intermediary may be removed at any time by the Company; and

                (iii) if the Securities Intermediary fails to perform any of its
         material obligations hereunder in any material respect for a period of
         not less than 20 days after receiving written notice of such failure by
         the Purchase Contract Agent and such failure shall be continuing, the
         Securities Intermediary may be removed by the Purchase Contract Agent,
         acting at the direction of the Holders of Securities.

                  The Purchase Contract Agent shall promptly notify the Company
of any notice of grounds for removal of the Securities Intermediary pursuant to
clause (iii) of this Section 8.10. Upon any resignation or removal of the
Collateral Agent, Custodial Agent or Securities Intermediary, the Company shall
have the right to appoint a successor Collateral Agent, Custodial Agent or
Securities Intermediary, as the case may be, which shall not be an Affiliate of
the Purchase Contract Agent. If no successor Collateral Agent, Custodial Agent
or Securities Intermediary shall have been so appointed and shall have accepted
such appointment within 30 days after the retiring Collateral Agent's, Custodial
Agent's or Securities Intermediary's giving of notice of resignation or the
Company's or the Purchase Contract Agent's giving notice of such removal, then
the retiring or removed Collateral Agent, Custodial Agent or Securities
Intermediary may petition any court of competent jurisdiction, at the expense of
the Company, for the appointment of a successor Collateral Agent, Custodial
Agent or Securities Intermediary. The Collateral Agent, the Custodial Agent and
the Securities Intermediary shall each be a bank or a national banking
association which has an office (or an agency office) in New York City with a
combined capital and surplus of at least $50,000,000. Upon the acceptance of any
appointment as Collateral Agent, Custodial Agent or Securities Intermediary
hereunder by a successor Collateral Agent, Custodial Agent or Securities
Intermediary, as the case may be, such

                                       20

<PAGE>

successor Collateral Agent, Custodial Agent or Securities Intermediary, as the
case may be, shall thereupon succeed to and become vested with all the rights,
powers, privileges and duties of the retiring Collateral Agent, Custodial Agent
or Securities Intermediary, as the case may be, and the retiring Collateral
Agent, Custodial Agent or Securities Intermediary, as the case may be, shall
take all appropriate action, subject to payment of any amounts then due and
payable to it hereunder, to transfer any money and property held by it hereunder
(including the Collateral) to such successor, and shall follow the Company's
instructions, if any, to ensure that the perfection of the Pledge is not
affected thereby. The retiring Collateral Agent, Custodial Agent or Securities
Intermediary shall, upon such succession, be discharged from its duties and
obligations as Collateral Agent, Custodial Agent or Securities Intermediary
hereunder. After any retiring Collateral Agent's, Custodial Agent's or
Securities Intermediary's resignation hereunder as Collateral Agent, Custodial
Agent or Securities Intermediary, the provisions of this Article 8 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as the Collateral Agent, Custodial Agent or
Securities Intermediary. Any resignation or removal of the Collateral Agent,
Custodial Agent or Securities Intermediary hereunder, at a time when such Person
is acting as the Collateral Agent, Custodial Agent or Securities Intermediary,
shall be deemed for all purposes of this Agreement as the simultaneous
resignation or removal of the Collateral Agent, Securities Intermediary or
Custodial Agent, as the case may be.

                  Section 8.11. Right to Appoint Agent or Advisor. The
Collateral Agent shall have the right to appoint agents or advisors in
connection with any of its duties hereunder, and the Collateral Agent shall not
be liable for any action taken or omitted by, or in reliance upon the advice of,
such agents or advisors selected in good faith. The appointment of agents
pursuant to this Section 8.11 shall be subject to prior written consent of the
Company, which consent shall not be unreasonably withheld.

                  Section 8.12. Survival. The provisions of this Article 8 shall
 survive termination of this Agreement and the resignation or removal of the
Collateral Agent, the Custodial Agent or the Securities Intermediary.

                  Section 8.13. Exculpation. Anything contained in this
Agreement to the contrary notwithstanding, in no event shall the Collateral
Agent, the Custodial Agent or the Securities Intermediary or their officers,
directors, employees or agents be liable under this Agreement to any third party
for indirect, special, punitive, or consequential loss or damage of any kind
whatsoever, including, but not limited to, lost profits, whether or not the
likelihood of such loss or damage was known to the Collateral Agent, the
Custodial Agent or the Securities Intermediary, or any of them and regardless of
the form of action.

                                   ARTICLE IX

                                    Amendment

                  Section 9.1. Amendment Without Consent of Holders. Without the

 the Securities Intermediary and the Purchase Contract Agent, at any time and
from time to time, may amend

                                       21

<PAGE>

Custodial Agent, the Securities Intermediary and the Purchase Contract Agent,
for any of the following purposes:

                  (i) to evidence the succession of another Person to the
         Company, and the assumption by any such successor of the covenants of
         the Company herein;

                 (ii) to add to the covenants of the Company for the benefit of
         the Holders, or to surrender any right or power herein conferred upon
         the Company so long as such covenants or such surrender do not
         adversely affect the validity, perfection or priority of the security
         interests granted or created hereunder;

                (iii) to evidence and provide for the acceptance of appointment
         hereunder by a successor Collateral Agent, Custodial Agent, Securities
         Intermediary or Purchase Contract Agent; or

                 (iv) to cure any ambiguity, to correct or supplement any
         provisions herein which may be inconsistent with any other such
         provisions herein, or to make any other provisions with respect to such
         matters or questions arising under this Agreement, provided such action
         shall not adversely affect the interests of the Holders.

                  Section 9.2. Amendment With Consent of Holders. With the
consent of the Holders of not less than a majority of the total Contracts at the
time outstanding voting together as one class, by Act of said Holders delivered
to the Company, the Purchase Contract Agent or the Collateral Agent, as the case
may be, the Company, the Purchase Contract Agent, the Collateral Agent, the
Custodial Agent and the Securities Intermediary may amend this Agreement for the
purpose of modifying in any manner the provisions of this Agreement or the
rights of the Holders in respect of the Securities; provided, however, that no
such supplemental agreement shall, without the consent of the Holder of each
Outstanding Security adversely affected thereby,

                  (i) change the amount or type of Collateral underlying a
         Security (except as contemplated by Article IV of this Agreement),
         impair the right of the Holder of any Security to receive distributions
         on the underlying Collateral or otherwise adversely affect the Holder's
         rights in or to such Collateral; or

                 (ii) otherwise effect any action that would require the consent
         of the Holder of each Security affected thereby pursuant to the
         Purchase Contract Agreement if such action were effected by an
         agreement supplemental thereto; or

                (iii) reduce the percentage of such Contracts the consent of
whose Holders is required for any such amendment.

It shall not be necessary for any Act of Holders under this Section to approve
the particular form of any proposed amendment, but it shall be sufficient if
such Act shall approve the substance thereof.

                  Section 9.3. Execution of Amendments. In executing any
amendment permitted by this Section, the Collateral Agent, the Custodial Agent,
the Securities Intermediary and the

                                       22

hereunder.

                  Section 9.4. Effect of Amendments. Upon the execution of any

therewith, and such amendment shall form a part of this Agreement for all

execution of any amendment pursuant to this Article IX may, and shall if

Attention:  Mr. David Moore

     Re:  Loan and Security Agreement by and among Heller Healthcare Finance,
          Inc. ("Lender") and Star Multi Care Services, Inc., Amserv Health Care
          of Ohio, Inc., Amserv Health Care of New Jersey, Inc. and EFCC
          Acquisition Corp. ("Borrower") dated as of August 31, 2001 (as amended
          from time to time, the "Loan Agreement")

Ladies and Gentlemen:

     Reference is made to the Loan Agreement. All capitalized terms used but not
defined in this Letter Agreement shall have the respective meanings given them
in the Loan Agreement.

     Borrower has requested that Lender agree to make periodic advances of Loan
proceeds (i.e., the "Overline Advances"), the aggregate of which will exceed the
principal amount currently permitted by the Loan Agreement to be advanced
against the Borrowing Base. Lender has agreed to make such Overline Advances
provided that Borrower agrees to the terms and conditions set forth below.

     Lender and Borrower hereby agree to the following terms regarding the
Overline Advances:

     1. The outstanding Overline Advances (the "Overline Loan") shall not exceed
at any time an aggregate maximum principal amount of One Hundred Seventy Six
Thousand and No/100 Dollars ($176,000.00).

     2. Except as expressly modified by the terms of this Letter Agreement, the
Overline Loan will be treated for all purposes as a Revolving Credit Loan under
the Loan Agreement, and all principal, interest, fees and other costs and
expenses relating to the Overline Loan (the "Overline Obligations") shall be
treated as additional Obligations under the Loan Agreement and the other Loan
Documents. The Maximum Loan Amount under the Loan Agreement shall be inclusive
of the Overline Loan.

     3. The Overline Loan shall continue to bear interest at the Base Rate as
specified in Loan Agreement. The Overline Loan shall be reduced monthly, on or
before the final day of each calendar month commencing with January 31, 2003, by
an amount equal to Fourteen Thousand Six Hundred Sixty Six and 67/100 Dollars
($14,666.67); provided, however, that, in any event, the Overline Obligations
shall be repaid in full by no later than December 31, 2003 (the "Overline
Maturity Date"). The failure to make any of the foregoing reductions of the
Overline Loan or the failure to make such repayment on or before the Overline
Maturity Date shall constitute an immediate Event of Default under the Loan
Agreement. Upon the occurrence of such an Event of Default, Lender shall be
entitled to apply amounts transferred to the Concentration Account pursuant to
Section 2.3 of the Loan Agreement in satisfaction of Borrower's Overline
Obligations.

<PAGE>

     4. Borrower shall pay to Lender a fee (the "Overline Fee") equal to ten
percent (10%) of the maximum amount of the Overline Loan advanced to Borrower
throughout the term of the Overline Loan, which amount shall not exceed
Seventeen Thousand Six Hundred Dollars ($17,600.00).

     5. The entire amount of the Overline Obligations shall be secured by
Unconditional Guaranties of Payment and Performance (i) by Stephen Sternbach, an
individual, and (ii) by Sternbach Enterprises, LLC ("LLC Guarantor") in favor of
Lender (the "LLC Guaranty"), which LLC Guaranty is further secured by a pledge
and assignment of all of LLC Guarantor's right, title and interest in and to all
of the shares owned by Guarantor in the 494 Ocean Harbor View Apartment Corp.,
as evidenced by Stock Certificates Nos. 82, 83, 85 and 86, representing 1,380
shares in 494 Ocean Harbor View Apartment Corp. and an assignment of certain
proprietary leases (collectively, the "Assignment"). The Assignment granted by
LLC Guarantor to Lender shall be free and clear of any other of any other person
or entity, except for the rights provided in the governing documents of 494
Ocean Harbor View Apartment Corp. All of the documents relating to the guaranty
and security agreements described herein shall be in form and substance
satisfactory to Lender. In addition to the Assignment, Borrower and LLC
Guarantor shall deliver to Lender a legal opinion in form and substance
acceptable to Lender addressing, among other things, the enforceability and
legality of this Letter Agreement, the LLC Guaranty and the Assignment.

     6. Except as specifically modified by this Letter Agreement, the Loan
Agreement and all other Loan Documents shall remain in full force and effect,
and are hereby ratified and confirmed.

     7. Borrower shall be responsible for the costs and expenses incurred by
Lender in connection with this Letter Agreement and the Assignment, including
the reasonable fees and expenses of Lender's in-house counsel.

     8. This Letter Agreement shall be governed by and construed in accordance
with the laws of the State of Maryland.

     9. The execution, delivery and effectiveness of this Letter Agreement shall
not, except as expressly provided in this Letter Agreement, operate as a waiver
of any right, power or remedy of Lender, nor constitute a waiver of any
provision of the Loan Agreement, or any other documents, instruments and
agreements executed or delivered in connection with the Loan Agreement.

     10. This Letter Agreement may be executed in any number of counterparts,
including by facsimile signature, each of which shall be deemed an original, but
all of which together shall constitute but one instrument.
