matters relating to the Securities. Agent shall act as trustee, paying agent,
fiscal agent, or other such agent of Issuer with respect to the Securities. The
Securities have been issued pursuant to a trust indenture, trust agreement,
pooling and servicing agreement or other such document authorizing the issuance
of the Securities dated October 1, 1993 (the "Document"). Morgan Stanley & Co.

----------

*        This Letter of Representations includes the Addendum attached hereto,
         which modifies and supercedes this Letter of Representations to the
         extent set forth therein.

<PAGE>

["Underwriter/Placement Agent"] is distributing the Securities
through The Depository Trust Company ("DTC").

                  To induce DTC to accept the Securities as eligible for deposit
at DTC, and to act in accordance with its Rules with respect to the Securities,
Issuer and Agent make the following representations to DTC:

                  1. Prior to closing on the Securities on January 23, 2002
there shall be deposited with DTC one or more Security certificates registered
in the name of DTC's nominee, Cede & Co., for each stated maturity of the
Securities in the face amounts set forth on Schedule A hereto, the total of
which represents 100% of the principal amount of such Securities. If however,
the aggregate principal amount of any maturity exceeds $400 million, one
certificate shall be issued with respect to each $400 million of principal
amount and an additional certificate shall be issued with respect to any
remaining principal amount. Each Security certificate shall bear the following
legend:

                           Unless this certificate is presented by an authorized
         representative of The Depository Trust Company, a New York corporation
         ("DTC"), to Issuer or its agent for registration of transfer, exchange,
         or payment, and any certificate issued is registered in the name of
         Cede & Co. or in such other name as is requested by an authorized
         representative of DTC (and any payment is made to Cede & Co. or to such
         other entity as is requested by an authorized representative of DTC),
         ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR
         TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede
         & Co., has an interest herein.

Issuer represents:

                  The Security certificate(s) shall remain in Agent's custody as
a "Balance Certificate" subject to the provisions of the Balance Certificate
Agreement between Agent and DTC currently in effect.

                  On each day on which Agent is open for business and on which
it receives an instruction originated by a DTC participant ("Participant")
through DTC's Deposit/Withdrawal at Custodian ("DWAC") system to increase the
Participant's account by a specified number of Securities (a "Deposit
Instruction"), Agent shall, no later than 6:30 p.m. (Eastern Time) that day,
either approve or cancel the Deposit Instruction through the DWAC system.

                  On each day on which Agent is open for business and on which
it receives an instruction originated by Participant through the DWAC system to
decrease the Participant's account by a specified number of Securities (a
"Withdrawal Instruction"), Agent shall, no later than 6:30 pm. (Eastern Time)
that day, either approve or cancel the Withdrawal Instruction through the DWAC
system.

<PAGE>

                  Agent agrees that its approval of a Deposit or Withdrawal
Instruction shall be deemed to be the receipt by DTC of a new reissued or
reregistered certificated Security on registration of transfer to the name of
Cede & Co. for the quantity of Securities evidenced by the Balance Certificate
after the Deposit or Withdrawal Instruction is effected.

                  2. Issuer: (a) understands that DTC has no Obligation to, and
will not, communicate to its Participants or to any person having an interest in
the Securities any information contained in the Security certificate(s); and (b)
acknowledges that neither DTC's Participants nor any person having an interest
in the Securities shall be deemed to have notice of the provisions of the
Security certificates by virtue of submission of such certificate(s) to DTC.

                  3. In the event of any solicitation of consents from or voting
by holders of the Securities, Issuer or Agent shall establish a record date for
such purposes (with no provision for revocation of consents or votes by
subsequent holders) and shall send notice of such record date to DTC no fewer
than 15 calendar days in advance of such record date. Notices to DTC pursuant to
this Paragraph by telecopy shall be directed to DTC's Reorganization Department,
Proxy Unit at (212) 855-5181 or (212) 855-5182. If the party sending the notice
does not receive a telecopy receipt from DTC confirming that the notice has been

this Paragraph, by mail or by any other means, shall be sent to:

                  4. In the event of a full or partial redemption, Issuer or
Agent shall send a notice to DTC specifying: (a) the amount of the redemption or
refunding; (b) in the case of a refunding, the maturity date(s) established
under the refunding; and (c) the date such notice is to be distributed to
Security holders (the "Publication Date"). Such notice shall be sent to DTC by a
secure means (e.g. legible telecopy, registered or certified mail, overnight
delivery) in a timely manner designed to assure that such notice is in DTC's
possession no later than the close of business on the business day before or, if
possible, two business days before the Publication Date. Issuer or Agent shall
forward such notice either in a separate secure transmission for each CUSIP
number or in a secure transmission for multiple CUSIP numbers (if applicable)
which includes a manifest or list of each CUSIP number submitted in that
transmission. (The party sending such notice shall have a method to verify
subsequently the use of such means and the timeliness of such notice). The
Publication Date shall be no fewer than 30 days nor more than 60 days prior to
the redemption date or, in the case of an advance refunding, the date that the
proceeds are deposited in escrow. Notices to DTC pursuant to this Paragraph by
telecopy shall be directed to DTC's Call Notification Department at (516)
227-4164 or (516) 227-4190. If the party sending the notice does not receive a

<PAGE>

such party shall telephone (516) 227-4070. Notices to DTC pursuant to this
Paragraph, by mail or by any other means, shall be sent to:

                               The Depository Trust Company
                               711 Stewart Avenue
                               Garden City, NY  11530-4719

                  5. In the event of an invitation to tender the Securities
(including mandatory tenders, exchanges, and capital changes), notice by Issuer
or Agent to Security holders shall be sent to DTC specifying the terms of the
tender and the Publication Date of such notice. Such notice shall be sent to DTC
by a secure means (e.g. legible telecopy, registered or certified mail,
overnight delivery) in a timely manner designed to assure that such notice is in
DTC's possession no later than the close of business on the business day before
or, if possible, two business days before the Publication Date. Issuer or Agent
shall forward such notice either in a separate secure transmission for each
CUSIP number or in a secure transmission for multiple CUSIP numbers (if

that transmission. (The party sending such notice shall have a method to verify
subsequently the use and timeliness of such notice.) Notices to DTC pursuant to
this Paragraph and notices of other corporate actions by telecopy shall be
directed to DTC's Reorganization Department at (212) 855-5488. If the party
sending the notice does not receive a telecopy receipt from DTC confirming that
the notice has been received, such party shall telephone (212) 855-5290. Notices

                  6. It is understood that if the Security holders shall at any
time have the right to tender the Securities to Issuer and require that Issuer
repurchase such holders' Securities pursuant to the document and Cede & Co., as
nominee of DTC, or its registered assigns, as the record owner, is entitled to
tender the Securities, such tenders will be effected by means of DTC's Repayment
Option Procedures. Under the Repayment Option Procedures, DTC shall receive,
during the applicable tender period, instructions from its Participants to
tender Securities for purchase. Issuer and Agent agree that such tender for
purchase may be made by DTC by means of a book-entry credit of such Securities
to the account of Agent, provided that such credit is made on or before the
final day of the applicable tender period. DTC agrees that promptly after the
recording of any such book-entry credit, it will provide to Agent an Agent
Receipt and Confirmation or the equivalent, in accordance with the Repayment
Option Procedures, identifying the Securities and the aggregate principal amount
thereof as to which such tender for purchase has been made.

                  Agent shall send DTC notice regarding such optional tender by
hand or by a secure means (e.g., legible facsimile transmission, registered or
certified mail, overnight delivery) in a timely manner designed to assure that
such notice is in DTC's possession no later than the close of business two
business days before the Publication Date. The Publication Date shall be no
fewer than 15 days prior to the expiration date of the applicable tender period.
Such notice shall

<PAGE>

state whether any partial redemption of the Securities is scheduled to occur
during the applicable optional tender period. Notices to DTC pursuant to this
Paragraph by telecopy shall be directed to DTC's Put Bond Unit at (212)
855-5235. If the party sending the notice does not receive a telecopy receipt
from DTC confirming that the notice has been received, such party shall
telephone (212) 855-5230. Notices to DTC pursuant to this Paragraph, by mail or
by any other means, shall be sent to:

<PAGE>

                  17. In the event of a redemption, acceleration, or any other
similar transaction (e.g., tender made and accepted in response to Issuer's or
Agent's invitation) necessitating a reduction in the aggregate principal amount
of Securities outstanding or an advance refunding of part of the Securities
outstanding, DTC, in its discretion: (a) may request Issuer or Agent to issue
and authenticate a new Security certificate; or (b) may make an appropriate
notation on the Security certificate indicating the date and amount of such
reduction in principal except in the case of final maturity, in which case the
certificate will be presented to Issuer or Agent prior to payment, if required.

                  18. In the event that Issuer determines that beneficial owners
of Securities shall be able to obtain certificated Securities, Issuer or Agent
shall notify DTC of the availability of certificates. In such event, Issuer or
Agent shall issue, transfer, and exchange certificates in appropriate amounts,
as required by DTC and others.

                  19. DTC may discontinue providing its services as securities
depository with respect to the Securities at any time be giving reasonable
notice to Issuer or Agent (at which time DTC will confirm with Issuer or Agent
the aggregate principal amount of Securities outstanding). Under such
circumstances, at DTC's request Issuer and Agent shall cooperate fully with DTC
by taking appropriate action to make available one or more separate certificates
evidencing Securities to any Participant having Securities credited to its DTC
accounts.

                  20. Nothing herein shall be deemed to require Agent to advance
funds on behalf of Issuer.

                  21. This Letter of Representations may be executed in any
number of counterparts, each of which when so executed shall be deemed to be an
original, but all such counterparts together shall constitute but one and the
same instrument.

                  22. This Letter of Representations shall be governed by, and
construed in accordance with, the laws of the State of New York, without giving
effect to principles of conflicts of law.

                  23. The sender of each notice delivered to DTC pursuant to
this Letter of Representations is responsible for confirming that such notice
was properly received by DTC.

                  24. Issuer recognizes that DTC does not in any way undertake
to, and shall not have any responsibility to, monitor or ascertain the
compliance of any transactions in the Securities with the following, as amended
from time to time: (a) any exemptions from registration under the Securities Act
of 1933; (b) the Investment Company Act of 1940; (c) the Employee Retirement

respect to the Securities from time to time at the request of the Agent. DTC
charges a fee for such SPLs. This authorization, unless

<PAGE>

Securities are on deposit at DTC, until and unless Agent shall no longer be
acting. In such event, Issuer shall provide DTC with similar evidence,
satisfactory to DTC, of the authorization of any successor thereto so to act.

Reorganization Department at (212) 855-5181 or (212) 855-5182. Receipt of such

                        SAMPLE OFFERING DOCUMENT LANGUAGE
                       DESCRIBING BOOK-ENTRY-ONLY ISSUANCE

     1. The Depository Trust Company ("DTC"), New York, NY, will act as
securities depository for the securities (the "Securities"). The Securities will
be issued as fully-registered securities registered in the name of Cede & Co.
(DTC's partnership nominee) or such other name as may be requested by an
authorized representative of DTC. One fully-registered Security certificate will
be issued for [each issue of] the Securities, [each] in the aggregate principal
amount of such issue, and will be deposited with DTC. [If, however, the
aggregate principal amount of [any] issue exceeds $400 million, one certificate
will be issued with respect to each $400 million of principal amount and an
additional certificate will be issued with respect to any remaining principal
amount of such issue.]

     2. DTC is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC holds securities that its participants ("Direct Participants")
deposit with DTC. DTC also facilitates the settlement among Direct Participants
of securities transactions, such as transfers and pledges, in deposited
securities through electronic computerized book-entry changes in Direct
Participants' accounts, thereby eliminating the need for physical movement of
securities certificates. Direct Participants include securities brokers and
dealers, banks, trust companies, clearing corporations, and certain other
organizations. DTC is owned by a number of its Direct Participants and by the
New York Stock Exchange, Inc., the American Stock Exchange LLC, an the National
Association of Securities Dealers, Inc. Access to the DTC system is also
available others such as securities brokers and dealers, banks, and trust
companies that clear through or maintain a custodial relationship with a Direct
Participant, either directly or indirectly ("Indirect Participants"). The Rules
applicable to DTC and its Direct and Indirect Participants are on file with the
Securities Exchange Commission.

     3. Purchases of Securities under the DTC system must be made by or through
Direct Participants, which will receive a credit for the Securities on DTC's
records. The ownership interest of each actual purchaser of each Security
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect
Participants' records. Beneficial Owners are expected to receive written
confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Direct or Indirect Participant through
which the Beneficial Owner entered into the transaction. Transfers of ownership
interests in the Securities are to be accomplished by entries made on the books
of Direct and Indirect Participants acting on behalf of Beneficial Owners.
Beneficial Owners will not receive certificates representing their ownership
interests in Securities, except in the event that use of the book-entry system
for the Securities is discontinued.

     4. To facilitate subsequent transfers, all Securities deposited by Direct
Participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. or such other name as may be requested by an authorized
representative of DTC. The deposit of Securities with DTC and their registration
in the name of Cede & Co. or such other nominee do not

<PAGE>

effect any change in beneficial ownership. DTC has no knowledge of the actual
Beneficial Owners of the Securities. DTC's records reflect only the identify of
the Direct Participants to whose accounts such Securities are credited, which
may or may not be the Beneficial Owners. The Direct and Indirect Participants
will remain responsible for keeping account of their holdings on behalf of their
customers.

     5. Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time. [Beneficial Owners of Securities may wish to
take certain steps to augment transmission to them of notices of significant
events with respect to the Securities, such as redemptions, tenders, defaults,
and proposed amendments to the security documents. Beneficial Owners of
Securities may wish to ascertain that the nominee holding the Securities for
their benefit has agreed to obtain and transmit notices of Beneficial Owners, or
in the alternative, Beneficial Owners may wish to provide their names and
addresses to the registrar and request that copies of the notices be provided
directly to them.]

     6. [Redemption notices shall be sent to DTC. If less than all of the
Securities within an issue are being redeemed, DTC's practice to determine by
lot the amount of the interest of each Direct Participant in such issue to be
redeemed.]

     7. Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or
vote with respect to the Securities. Under its usual procedures, DTC mails an
Omnibus Proxy to Issuer as soon as possible after the record date. The Omnibus
Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts the Securities are credited on the record date
(identified in a listing attached to the Omnibus Proxy).

     8. Redemption proceeds, distributions, and dividend payments on the
Securities will be made to Cede & Co., or such other nominee as may be requested
by an authorized representative of DTC. DTC's practice is to credit Direct
Participants' accounts, upon DTC's receipt of funds and corresponding detail
information from Issuer or Agent on payable date in accordance with their
respective holdings shown on DTC's records. Payments by Participants to
Beneficial Owners will be governed by standing instructions and customary
practices, as is the case with securities held for the accounts of customers in
bearer funds or registered in "street name," and will be the responsibility of
such Participant and not of DTC, Agent, or Issuer, subject to any statutory or
regulatory requirements as may be in effect from time to time. Payment of
redemption proceeds, distributions, and dividends to Cede & Co. (or such other
nominee as may be requested by an authorized representative of DTC) is the
responsibility of Issuer or Agent, disbursement of such payments to Direct
Participants shall be the responsibility of DTC, and disbursement of such
payments to the Beneficial Owners shall be the responsibility of Direct and
Indirect Participants.

     9. [A Beneficial Owner shall give notice to elect to have its Securities
purchased or tendered, through its Participant, to [Tender/Remarketing] Agent,
and shall effect delivery of such Securities by causing the Direct Participant
to transfer the Participant's interest in the Securities, on DTC's records, to
[Tender/Remarketing] Agent. The requirement for physical delivery of Securities
in connection with an optional tender or a mandatory purchase will be deemed
satisfied when the ownership rights in the Securities are transferred by Direct

<PAGE>

Participants on DTC's records and followed by a book-entry credit of tendered
Securities to [Tender/Remarketing] Agent's DTC account.]

     10. DTC may discontinue providing its services as securities depository
with respect to the Securities at any time by giving reasonable notice to Issuer
or Agent. Under such circumstances, in the event that a successor securities
depository is not obtained, Security certificates are required to be printed and
delivered.

     11. Issuer may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository). In that event,
Security certificates will be printed and delivered.

     12. The information in this section concerning DTC and DTC's book-entry
system has been obtained from sources that Issuer believes to be reliable, but
Issuer takes no responsibility for the accuracy thereof.

                                                                    CONFIDENTIAL

               of authorized directors of the Parent as determined in the manner
               prescribed in the Parent's Articles of Incorporation and Bylaws;
               provided, however, that if the election, or nomination for
               election, by the Parent's stockholders of any new director was
               approved by a vote of at least fifty percent (50%) of the

               Existing Director; provided further, however, that no individual

               threatened "Election Contest" (as described in Rule 14a-11
               promulgated under the Exchange Act) or other actual or threatened
               solicitation of proxies by or on behalf of anyone other than the
               board of directors of the Parent (a "Proxy Contest"), including
               by reason of any agreement intended to avoid or settle any
               Election Contest or Proxy Contest.

        (c)    The consummation of (x) a merger, consolidation or reorganization
               to which an Employer or the Parent is a party, whether or not the

               therefrom, or (y) a sale, assignment, lease, conveyance or other
               disposition of all or substantially all of the assets of the an
               Employer or the Parent, in one transaction or a series of related
               transactions, to any Person other than a wholly owned subsidiary
               (including lower tier subsidiaries) of the Parent, where any such
               transaction or series of related transactions as is referred to
               in clause (x) or clause (y) above in this subparagraph (c)
               (singly or collectively, a "Transaction") does not otherwise
               result in a "Change in Control" pursuant to subparagraph (a) of
               this definition of "Change in Control"; provided, however, that
               no such Transaction shall constitute a "Change in Control" under
               this subparagraph (c) if the Persons who were the stockholders of
               the Parent immediately before the consummation of such
               Transaction are the Beneficial Owners (within the meaning of Rule
               13d-3 under the Exchange Act), immediately following the
               consummation of such Transaction, of fifty percent (50%) or more
               of the combined voting power of the then outstanding voting
               securities and the value of the then outstanding equity
               securities of all classes (voting or non-voting) of the Person
               surviving or resulting from any merger, consolidation or
               reorganization referred to in clause (x) above in this
               subparagraph (c) or the Person to whom the assets of the Employer
               or the Parent are sold, assigned, leased, conveyed or disposed of
               in any transaction or series of related transactions referred to
               in clause (y) above in this subparagraph (c), in substantially
               the same proportions in which such Beneficial Owners held voting
               stock in the Parent immediately before such Transaction.

        (d)    The Parent or an Employer voluntarily files a petition for
               bankruptcy under Federal bankruptcy law, or an involuntary
               bankruptcy petition is filed against the Parent or an Employer
               under federal bankruptcy law, which involuntary petition is not
               dismissed within 120 days after the filing.

        the Rights Agreement, dated as of April 10, 1996, between Parent and

        With respect to Sections 1.4(d), (e) and (f) above, if the event

               Date").

               date. The Retention Benefit shall be calculated as of the payment
               date and shall be paid to the Participant, or his or her
               Beneficiary, within 90 days of the Forfeiture Lapse Date.

        (b)    PARTICIPANT'S ACCOUNT. Within 60 days of the end of each calendar
               year quarter (March 31, June 30, September 30, December 31), each

               of his or her Participant's Account as of the end of such period.

4.2     EMPLOYER BENEFIT.

        (a)    ELIGIBILITY. The Participant's Employer shall be entitled to a
               contingent "Employer Benefit,"described in Section 4.2(b) below,
               if:

                   (i)       A Participant Retires, dies, suffers a Disability
                             or experiences a Termination of Employment prior to
                             90 days prior to a Change in Control;

                   (ii)      A Participant voluntarily terminates his or her
                             employment (other than by death, Retirement or
                             Disability) with all of his or her Employers at any
                             time on or after 90 days prior to the date of a
                             Change in Control and prior to the later of (i) six

                             (ii) January 1 of the Plan Year following the
                             Change in Control; or

                   (iii)     There is a positive balance in the Employer Death
                             Benefit Account.

         (b)   BENEFIT AND PAYMENT. The "Employer Benefit" shall be a dollar
               amount that is equal to the balance of a Participant's Account
               who forfeits his or her rights to such Participant's Retention
               Benefit, measured as of the date of payment. In the case of
               4.2(a)(iii), the Employer Benefit shall be an amount equal to the
               Employer Death Benefit Account. The Employer Benefit shall be

                               ARTICLE 5     BENEFICIARY

5.1     BENEFICIARY. Each Participant shall have the right, at any time, to
        designate his or her Beneficiary (both primary as well as contingent) to
        receive any benefits payable under the Plan to a Beneficiary upon the
        death of a Participant.

5.2     BENEFICIARY DESIGNATION; CHANGE; SPOUSAL CONSENT. A Participant shall
        designate his or her Beneficiary by completing and signing the
        Beneficiary Designation Form, and returning it to the Committee or its
        designated agent. A Participant shall have the right to change a
        Beneficiary by completing, signing and otherwise complying with the
        terms of the Beneficiary Designation Form and the Committee's rules and
        procedures, as in effect from time to time. If the Participant names
        someone other than his or her spouse as a Beneficiary, a spousal
        consent, in the form designated by the Committee, must be signed by that
        Participant's spouse and returned to the Committee. Upon the acceptance
        by the Committee of a new Beneficiary Designation Form, all Beneficiary
        designations previously filed shall be canceled. The Committee shall be
        entitled to rely on the last Beneficiary Designation Form filed by the
        Participant and accepted by the Committee before his or her death.

5.3     ACKNOWLEDGMENT. No designation or change in designation of a Beneficiary
        shall be effective until received, accepted and acknowledged in writing
        by the Committee or its designated agent.

5.4     NO BENEFICIARY DESIGNATION. If a Participant fails to designate a
        Beneficiary as provided in Sections 5.1, 5.2 and 5.3 above, or if all
        designated Beneficiaries predecease the Participant or die prior to
        complete distribution of the Participant's benefits, then the
        Participant's designated Beneficiary shall be deemed to be his or her
        surviving spouse. If the Participant has no surviving spouse, the
        benefits remaining under the Plan shall be paid to the Participant's
        issue upon the principle of representation, and if there is no such
        issue, to the executor or personal representative of the Participant's
        estate.

5.5     DOUBT AS TO BENEFICIARY. If the Trustee has any doubt as to the proper
        Beneficiary to receive payments pursuant to this Plan, the Trustee shall
        have the right, exercisable in its discretion, to withhold such payments
        until this matter is resolved to the Trustee's satisfaction.

5.6     DISCHARGE OF OBLIGATIONS. The payment of benefits under the Plan to a
        Beneficiary shall fully and completely discharge all Employers and the
        Committee from all further obligations under this Plan with respect to
        the Participant, and that Participant's Plan Agreement shall terminate
        upon such full payment of benefits.

6.1     TERMINATION, AMENDMENT OR MODIFICATION PRIOR TO ONE YEAR BEFORE CHANGE
        IN CONTROL. Prior to one year before a Change in Control, each Employer
        reserves the right to terminate, amend or modify the Plan or any related
        Plan Agreement, in whole or in part, with respect to Participants whose
        services are retained by that Employer. Notwithstanding the foregoing,
        no termination, amendment or modification shall be effective to decrease
        or reduce a Participant's potential benefits under this Plan below the
        balance in his or her Participant's Account as of the effective date of
        the termination, amendment or modification, adjusted for investment
        gains and losses thereon.

6.2     TERMINATION, AMENDMENT OR MODIFICATION WITHIN ONE YEAR BEFORE CHANGE IN
        CONTROL OR FOLLOWING CHANGE IN CONTROL. Within one year before a Change
        in Control and thereafter ("No Change Period"), the Parent, the Company,
        any subsidiary of the Company, any Employer or any corporation, trust or
        other Person that succeeds to all or any substantial portion of the
        assets of any of the above described entities, shall not have the right
        to terminate, amend or modify the Plan and/or any Plan Agreement in
        effect prior to such Change in Control, and all benefits under the Plan
        and any such Plan Agreement shall thereafter be paid in accordance with
        the terms of the Plan and such Plan Agreement, as in effect immediately
        prior to the No Change Period. If the Plan is terminated, amended, or
        modified within the No Change Period, such termination, amendment or
        modification shall be considered void as of the date of the termination,
        amendment or modification. Any provision of this Plan or any Plan
        Agreement to the contrary shall be construed in accordance with this
        Section 6.2.

6.3     TERMINATION OF PLAN AGREEMENT. Absent the earlier termination,
        modification or amendment of the Plan, or a Participant's forfeiture of
        his or her benefits under this Plan, the Plan Agreement of any
        Participant shall terminate upon the full payment of the applicable
        benefit provided under Article 4.

                                    ARTICLE 7    OTHER BENEFITS AND AGREEMENTS

7.1     COORDINATION WITH OTHER BENEFITS. The benefits provided for a
        Participant and Participant's Beneficiary under the Plan are in addition
        to any other benefits available to such Participant under any other plan
        or program for employees. The Plan shall supplement and shall not
        supersede, modify or amend any other such plan or program except as may
        otherwise be expressly provided.

8.1     ESTABLISHMENT OF THE TRUST; PREMIUMS. The Employers shall establish the
        Trust and shall at least annually transfer over to the Trust such assets
        as the Committee determines in its sole and absolute discretion. If
        directed by the Committee, the Employers shall pay any and all Policy
        premiums and other costs directly to the Insurer. In addition, if the
        Trust incurs any tax liability, the Employers shall contribute to the
        Trust sufficient funds to allow the Trustee to pay any such tax
        liability.

8.2     INTERRELATIONSHIP OF THE PLAN AND THE TRUST. The provisions of the Plan
        and each Plan Agreement shall govern the rights of a Participant to
        receive distributions pursuant to the Plan. The provisions of the Trust
        shall govern the rights of the Trustee, Participant and a Participant's
        Beneficiary as to the assets of the Trust. The Employers shall at all
        times remain liable to carry out their obligations under the Plan. The
        Employers and the Company shall cooperate with each other as is
        necessary to minimize the Trust's tax liability.

8.3     ACCOUNTS.

        (a)    The Trustee shall establish and maintain the following separate
               accounts:

               (i)      A "Participant's Account" for each Participant, to which
                        the Employers' contributions, or a portion thereof, and
                        earnings thereon shall be allocated, and the amount of
                        such Participant's Account (which can be expressed in
                        dollar terms or as an undivided percentage of the entire
                        Trust corpus) shall be used to calculate the Retention
                        Benefit or the Employer Benefit in accordance with this
                        Plan and the Trust;

               (ii)     An "Administrative Account" for the administrative
                        expenses of the Trust, to which a portion of the
                        Employers' contributions and earnings thereon may be
                        allocated to and held, the assets of which are to be
                        used to pay the administrative expenses, including all
                        taxes, of the Trust in accordance with the terms and
                        provisions of this Plan and the Trust; and

               (iii)    A "Employer Death Benefit Account" to which shall be
                        allocated the amount described in this subsection. In
                        the event of the death of an insured who is insured by a
                        Policy, the excess of (a) the death benefit received
                        from such Policy over (b) the cash surrender value of
                        such Policy as of the date immediately preceding the
                        death of the insured, shall be allocated to the Employer
                        Death Benefit Account. Such amount shall be distributed
                        as an Employer Benefit pursuant to Section 4.2(b).

        (b)    Prior to the date that is 90 days prior to a Change in Control,
               the Committee shall direct the Trustee in writing as to the
               allocation of the Employers' contributions, and earnings of the
               Trust, to the accounts described in Section 8.3(a)(i) & (ii)
               above as of the end of a calendar year quarter (March 31, June
               30, September 30, December 31) as soon as practicable after the
               end of such calendar year quarter. After a Change

               last quarterly statement received from the Committee prior to the
               date that is 90 days prior to a Change in Control, and shall
               allocate any change in the value of the assets in the Trust among
               the accounts based on the percentage interest in the assets of
               the Trust that each account had as of the date of such written
               statement, based on the fair market value of the assets in the
               Trust on the date of such written statement.

        (c)    Each of the accounts described in Section 8.3(a) above shall
               qualify for and be treated as separate shares under Code Section
               663(c).

        or more Policies in the Trustee's name. Such direction shall include the
        Insurer, type of contract and amount. The Trustee shall be the sole and
        absolute owner and beneficiary of each Policy, with all rights of an
        owner and beneficiary, including without limitation, the right to
        surrender Policies for their cash surrender values and to take one or
        more loans against one or more Policies. Notwithstanding the foregoing,

        and the Trust.

9.2     DOCUMENTS REQUIRED BY INSURER. The Trustee, the Participant's Employer
        and the Participant shall sign such documents and provide such
        information as may be required from time to time by the Insurer.

10.1    COMMITTEE DUTIES. This Plan shall be administered by a Committee which

10.4    INDEMNITY OF COMMITTEE. All Employers shall indemnify and hold harmless
        the members of the Committee against any and all claims, losses,

        (b)    specific reference(s) to the pertinent Plan provisions upon which
               the decision was based; and

        (c)    such other matters as the Committee deems relevant.

11.5    LEGAL ACTION. A Claimant's compliance with the foregoing provisions of
        this Article 11 is a mandatory prerequisite to a Claimant's right to
        commence any litigation with respect to any claim for benefits under
        this Plan.

                                    ARTICLE 12    MISCELLANEOUS

12.1    UNSECURED GENERAL CREDITOR. Participants and their Beneficiaries, heirs,
        successors and assigns shall have no legal or equitable rights, interest
        or claims in any property or assets of an Employer. Any and all of an
        Employer's assets shall be, and remain, the general, unpledged and
        unrestricted assets of the Employer. An Employer's obligation under the
        Plan shall be merely that of an unfunded and unsecured promise to pay
        money in the future.

                                                                    ------------

12.2    EMPLOYER'S LIABILITY. An Employer's liability for the payment of
        benefits shall be defined only by the Plan and the Plan Agreement, as
        entered into between the Employer and a Participant. An Employer shall
        have no obligation to a Participant under the Plan except as expressly
        provided in the Plan and his or her Plan Agreement.

12.3    NONASSIGNABILITY. Neither a Participant nor any other person shall have
        any right to commute, sell, assign, transfer, pledge, anticipate,
        mortgage or otherwise encumber, transfer, hypothecate or convey in
        advance of actual receipt, the amounts, if any, payable hereunder, or
        any part thereof, which are, and all rights to which are expressly
        declared to be, unassignable and non-transferable, except that the
        foregoing shall not apply to any family support obligations set forth in
        a court order. No part of the amounts payable shall, prior to actual
        payment, be subject to seizure or sequestration for the payment of any
        debts, judgments, alimony or separate maintenance owed by a Participant
        or any other person, nor be transferable by operation of law in the
        event of a Participant's or any other person's bankruptcy or insolvency.

12.4    NOT A CONTRACT OF EMPLOYMENT. The terms and conditions of this Plan
        shall not be deemed to constitute a contract of employment between any
        Employer and the Participant. Such employment is hereby acknowledged to
        be an "at will" employment relationship that can be terminated at any
        time for any reason, with or without cause, unless expressly provided in
        a written employment agreement. Nothing in this Plan shall be deemed to
        give a Participant the right to be employed in the service of any
        Employer, or to interfere with the right of any Employer to discipline
        or discharge the Participant at any time.

12.5    FURNISHING INFORMATION. A Participant will cooperate with the Committee
        by furnishing any and all information requested by the Committee and
        take such other actions as may be requested in order to facilitate the
        administration of the Plan and the payments of benefits hereunder,
        including but not limited to taking such physical examinations as the
        Committee may deem necessary.

12.6    TERMS. Whenever any words are used herein in the singular or in the
        plural, they shall be construed as though they were used in the plural
        or the singular, as the case may be, in all cases where they would so
        apply.

12.7    CAPTIONS. The captions of the articles, sections and paragraphs of this
        Plan are for convenience only and shall not control or affect the
        meaning or construction of any of its provisions.

12.8    GOVERNING LAW. The provisions of this Plan shall be construed and
        interpreted according to the laws of the State of Michigan, without
        regard to principles of conflict of laws.

12.9    VALIDITY. In case any provision of this Plan shall be illegal or invalid
        for any reason, said illegality or invalidity shall not affect the
        remaining parts hereof, but this Plan shall be construed and enforced as
        if such illegal and invalid provision had never been inserted

        herein.

12.10   NOTICE. Any notice or filing required or permitted to be given to the
        Committee under this Plan shall be sufficient if in writing and
        hand-delivered, or sent by registered or certified mail, to the address
        below:

               L. Perrigo Company
               515 Eastern Avenue
               Allegan, Michigan 49010
               Attention: Senior Vice President, Human Resources

        Such notice shall be deemed given as of the date of delivery or, if
        delivery is made by mail, as of the date shown on the postmark on the
        receipt for registration or certification.

        Any notice or filing required or permitted to be given to a Participant
        under this Plan shall be sufficient if in writing and hand-delivered,
        or sent by mail, to the last known address of the Participant.

12.11   SUCCESSORS. The provisions of this Plan shall bind and inure to the
        benefit of the Participant's Employer and its successors and assigns and
        the Participant, the Participant's Beneficiaries, and their permitted
        successors and assigns.

12.12   SPOUSE'S INTEREST. The interest in the benefits hereunder of a spouse of
        a Participant who has predeceased the Participant shall automatically
        pass to the Participant and shall not be transferable by such spouse in
        any manner, including but not limited to such spouse's will, nor shall
        such interest pass under the laws of intestate succession.

12.13   INCOMPETENT. If the Committee determines in its discretion that a
        benefit under this Plan is to be paid to a minor, a person declared
        incompetent or to a person incapable of handling the disposition of that
        person's property, the Committee may direct payment of such benefit to
        the guardian, legal representative or person having the care and custody
        of such minor, incompetent or incapable person. The Committee may
        require proof of minority, incompetency, incapacity or guardianship, as
        it may deem appropriate prior to distribution of the benefit. Any
        payment of a benefit shall be a payment for the account of the
        Participant and the Participant's Beneficiary, as the case may be, and
        shall be a complete discharge of any liability under the Plan for such
        payment amount.

12.14   DISTRIBUTION IN THE EVENT OF TAXATION. If, for any reason, all or any
        portion of a Participant's benefit under this Plan becomes taxable to
        the Participant prior to the Forfeiture Lapse Date, a Participant may
        petition the Committee, if prior to a Change in Control, or the Trustee,
        after a Change in Control, for a distribution of assets sufficient to
        meet the Participant's tax liability (including additions to tax,
        penalties and interest). Upon the grant of such a petition, which grant
        shall not be unreasonably withheld, the Trustee shall

                                                                    ------------

        distribute to the Participant from the Trust immediately available funds
        in an amount equal to that Participant's federal, state and local tax
        liability associated with such taxation, which liability shall be
        measured by using that Participant's then current highest federal, state
        and local marginal tax rate, plus the rates or amounts for the
        applicable additions to tax, penalties and interest. If the petition is
        granted, the tax liability distribution shall be made within 90 days of
        the date when the Participant's petition is granted.

12.15   LEGAL FEES TO ENFORCE RIGHTS AFTER CHANGE IN CONTROL. The Company is
        aware that upon the occurrence of a Change in Control, the Board (which
        might then be composed of new members), or a shareholder of the Company,
        an Employer or of any successor corporation, might then cause or attempt
        to cause the Company, an Employer or such successor to refuse to comply
        with its obligations under the Plan and might cause or attempt to cause
        the Company or an Employer to institute, or may institute, litigation
        seeking to deny Participants the benefits intended under the Plan. In
        these circumstances, the purpose of the Plan could be frustrated.
        Accordingly, if, following a Change in Control, it should appear to any
        Participant that the Company, an Employer or the Committee has failed to
        comply with any of its obligations under the Plan or any agreement
        thereunder or, if the Company, an Employer or any other person takes any
        action to declare the Plan or the Trust void or unenforceable or
        institutes any litigation or other legal action designed to deny,
        diminish or to recover from any Participant or Beneficiary the benefits
        intended to be provided, including without limitation the assets in the
        Trust, then the Company and the Employer of the Participant (or the
        former Employer of a deceased Participant in the case of a Beneficiary)
        irrevocably authorizes such person to retain counsel of his or her
        choice at the expense of the Company and such Employer (who shall be
        jointly and severally liable) to represent such person in connection
        with the initiation or defense of any litigation or other legal action,
        whether by or against the Company, the Employer, the Committee, or any
        director, officer, shareholder or other person affiliated with the
        Company or any successor thereto in any jurisdiction.
