the applicable rate per annum specified above (subject to the provisions of
paragraph 7) and on overdue principal, premium and interest at the rates
specified therein; and the Notes, when issued, sold and delivered pursuant to
the Agreements, will be substantially in the form of Exhibit A-1. Interest on
the Notes shall accrue at the applicable rate per annum specified above (subject
to the provisions of paragraph 7), which interest will be payable semiannually
as provided in Exhibit A-1 and will be computed based on a 360-day year
comprised of 12 months of 30 days each.

     Certain capitalized terms used in this Agreement are defined in paragraph
12; references to a paragraph are, unless otherwise specified, to one of the
paragraphs of this Agreement and references to an "Exhibit" are, unless
otherwise specified, to one of the exhibits attached to this Agreement.

     2. PURCHASE AND SALE OF NOTES; CLOSING. Subject to the terms and conditions
        -----------------------------------
herein set forth, the ESOP hereby agrees to sell to you, and you agree to
purchase from the ESOP, Notes in the aggregate principal amount and of the
series set forth opposite your name in the Purchaser Schedule attached hereto,
in the form of one or more Notes registered in your name or that of your
nominee, as you shall request, and in such denominations (subject to paragraph
14D) as you shall request, for an aggregate purchase price of 100% of the
principal amount thereof.

     The issuance, sale and delivery of Notes to be purchased by you shall take
place at 10:00 A.M., New York City time, on June 20, 1989, at the offices of
Willkie Farr & Gallagher, 153 East 53rd Street, New York, New York, or on such
other date as the Company, the ESOP, you and the Other Purchasers may agree upon
(the "Closing"). At the Closing, the ESOP will deliver to you the Notes to be
purchased by you against payment of the purchase price therefor by wire transfer
of immediately available funds to Mellon Bank, N.A., Pittsburgh, Pennsylvania,
for credit to the account of the ESOP, account no. 184-588. If at the Closing
the ESOP shall fail to tender to you the Notes to be purchased by you as
provided above in this paragraph 2, or if any of the conditions specified in
paragraph 3 shall not have been satisfied or waived by you, you shall, at your
election, be relieved of all further obligations under this Agreement, without
thereby waiving any other rights you may have by reason of such failure or such
non-fulfillment.

     Concurrently with the exclusion and delivery of this Agreement, the ESOP
and the Company are entering into other Note Purchase Agreements (herein
referred to as the "Other

                                      -2-
<PAGE>

Agreements" and, with this Agreement, as the "Agreements"), identical with this
Agreement (except as to the identity of the purchaser and the series and
principal amount of Notes to be purchased thereunder) with the other purchasers
(herein called the "Other Purchasers") named in the Purchaser Schedule attached
hereto. The sale of the Notes to you and to the Other Purchasers are to be
separate and several sales.

     Notwithstanding the foregoing provisions, the ESOP shall not be required to
issue the Notes under the Agreements if you or any of the Other Purchasers
defaults in its obligation to purchase Notes under its Agreement.

     3. CONDITIONS FOR CLOSING. Your obligation to purchase and pay for the
        ----------------------
Notes to be purchased by you at the Closing is subject to the satisfaction or
waiver, prior to or simultaneously and concurrently with the Closing, of the
following conditions:

         -------------------
Ingersoll, P.C., counsel to the Company, (ii) Lee, Toomey & Kent, counsel to the
ESOP, (iii) Jones, Day, Reavis & Pogue, counsel to the Trustee, and (iv) Willkie
Farr & Gallagher, your special counsel in connection with the transactions
contemplated by this Agreement, favorable opinions substantially in the forms
set forth in Exhibits B-1, B-2, B-3 and B-4, respectively, each addressed to you
and dated the date of the Closing. To the extent that any opinion referred to

counsel, you shall have received a copy of the opinion of such other counsel,
dated the date of the Closing and addressed to you, or a letter from such other
counsel, dated the date of the Closing and addressed to you, authorizing you to
rely on such other counsel's opinion.

     3B. REPRESENATIONS AND WARRANTIES; NO DEFAULT. The representations and
         -----------------------------------------
warranties of the ESOP and the Company contained in paragraph 10 of this
Agreement shall be true when made and at the time of the Closing in all material
respects, and there shall exist at the time of the Closing and after giving
effect to the transactions contemplated hereby, no Event of Default or Default
or Purchase Event. Each of the ESOP and the Company shall have delivered to you
a certificate (which shall be an Officer's Certificate in the case of the
Company), dated the date of the Closing, to all such effects (but limited to the
representations and warranties of the ESOP in the case of the ESOP) and further

     3C. PURCHASE PERMITTED BY APPLICABLE LAWS. The purchase of and payment for
         -------------------------------------
the Notes to be purchased by you on the date of the Closing on the terms and
conditions herein provided (including the use of the proceeds of such Notes by
the ESOP) shall not violate any applicable law or governmental regulation
(including, without limitation, Section 5 of the Securities Act or Regulation G,
T, U or X of the Board of Governors of the Federal Reserve System) or result in
a violation of any order of any court or governmental body applicable to you (or
any of your employees, directors or affiliates) and shall not subject you to any
tax, penalty, liability or other onerous condition under or pursuant to any
applicable law or governmental regulation or order, and you shall have received
such certificates or other evidence as you may request to establish compliance
with this condition.

     3D. ESOP TRANSACTION. Prior to the Closing, you shall have received true
         ----------------
and correct copies of the Plan Documents and all other documents having the
legal effect of governing the terms or administration of the ESOP; all the terms
and provisions thereof shall be satisfactory to you in form and substance
(including schedules and exhibits thereto); all such agreements, documents and
instruments shall be in full force and effect and no term or condition thereof
shall have been amended, modified or waived except with your prior consent; the
Trustee shall have made appropriate determinations satisfactory to you
establishing that neither the sale of the Notes to you nor the purchase of the
Employer Capital Stock as contemplated by the Stock Purchase Agreement nor the
consummation of the transactions contemplated by this Agreement is or will
constitute a "prohibited transaction" as such term is defined in section 406 of
ERISA or section 4975 of the Code for which there is no exemption; and the
purchase of Employer Capital Stock in the ESOP Transaction shall be duly and
validly consummated concurrently with the Closing hereunder. Except as affected
by the transactions contemplated hereby, all conditions precedent to the
consummation of the transactions contemplated by the Plan Documents shall have
occurred, all governmental authorizations, consents, approvals, exemptions or
other actions required in connection with such transactions shall have been duly
received or taken (except for the determination letter from the Internal Revenue
Service described in paragraph 5G and the registrations and filings referred to

                                      -5-
<PAGE>

"Installment Payment Date." Upon issuance of any Note, the ESOP will annex
thereto an amortization schedule with respect to such Note, setting forth the
amount of each Required Installment Payment to be allocated and applied on such
Note and the amount of the principal of such Note which will remain unpaid after
each such Required Installment Payment is made. Each Required Installment
Payment shall be allocated and applied on all outstanding Notes of a series in
proportion to the respective unpaid principal amounts thereof. Any payment made
by the ESOP pursuant to any other provision of this paragraph 4 shall not reduce
or otherwise affect its obligation to make any payment required by this

ESOP or the Company, its Subsidiaries or Affiliates (whether pursuant to
paragraph 4F or paragraph 8), the amount of the Required Installment Payments in
respect of the outstanding Notes of such series shall remain as specified on

all Notes of a series prepaid (except pursuant to subparagraph (a) of paragraph
4B or paragraph 4C), or otherwise retired or purchased or otherwise acquired by
the ESOP or the Company or any of its Subsidiaries or Affiliates and (y) all
Notes prepaid pursuant to subparagraph (b) of paragraph 4B, shall be deemed
outstanding. The ESOP shall deliver to the holder of each Note outstanding after
any such prepayment, retirement, purchase or acquisition a revised amortization
schedule with respect to such Note, setting forth the amount of each Required
Installment Payment thereafter to be allocated and applied on such Note and the
amount of the principal of such Note which will remain unpaid after each such
Required Installment Payment is made.

     4B. OPTIONAL PREPAYMENT WITHOUT PREMIUM. (a) The Notes of each series shall
         -----------------------------------
be subject to prepayment in part, at the option of the ESOP, on any Installment
Payment Date in an aggregate principal amount not to exceed 20% of the Required
Installment Payment to be made on the Notes of such series on such date (and not
to be less than $250,000), at 100% of the principal amount so to be prepaid,
together with accrued interest thereon to the prepayment date, but without
premium. The right of the ESOP to prepay Notes pursuant to this paragraph 4B
shall be non-cumulative and shall not, to the extent not fully exercised with
respect to any Installment Payment Date, increase the amount of Notes which the
ESOP may prepay on any subsequent Installment Payment Date pursuant to this

     thereon to the prepayment date, but without premium. Such prepayment shall

     held by Wachovia Bank and Trust Company, N.A. in inverse order of their
     maturity.

Notes at the time outstanding upon economically equivalent terms and conditions.
To the extent that any holder of the Notes declines such offer (or shall fail to
accept such offer within the time period specified therein, which shall be not

         --------------------
Subsidiaries to, comply with the requirements of all applicable laws and

and employee safety), the failure to comply with which would have a material
adverse effect on the business, properties, financial condition or results of
operations of the Company and its Subsidiaries taken as a whole. For purposes of
this paragraph 5F, any such failures will be deemed to have such a material
adverse effect if the liabilities incurred or reasonably expected to be incurred

54.4975-11 and the requirements, if any, that may be promulgated from time to
time with respect to section 133 of the Code; (ii) do all things necessary to

Plan Document in a manner that would result in the extension of credit
represented by the Notes ceasing to qualify as a "securities acquisition loan"
within the meaning of section 133(b) of the Code. The Company covenants that it
will make contributions to the ESOP as required by the Plan Documents. Nothing
in this paragraph 5H is intended to give any Person, other than the holders from
time to time of the Notes, any rights.

     5I. APPLICATION OF PROCEEDS. The ESOP shall use the entire proceeds of the
         -----------------------
issuance and sale of the Notes promptly to acquire, at not more than adequate
consideration (within the meaning of Section 3(18) of ERISA), shares of Employer

such case effectively providing concurrently with the issuance, assumption or
guaranty of any such Debt that the Company Obligations shall be secured equally

as such Debt shall be so secured, unless after giving effect thereto the
aggregate amount of all such Debt so secured, together with all Attributable
Debt in respect of sale and leaseback transactions involving Principal
Properties, would not exceed 10% of Consolidated Net Tangible Assets. The
foregoing restrictions shall not prevent, restrict or apply to Debt secured by:
(1) Liens on property, shares of stock or indebtedness of any corporation
existing at the time such corporation becomes a Restricted Subsidiary, provided
that any such Lien was in existence prior to the time such corporation became a
Restricted Subsidiary and was not effected in contemplation of such
corporation's becoming a Restricted Subsidiary; (2) Liens on any property
(including shares of stock or Debt) existing at the time of acquisition thereof
or securing the payment of all or any part of the purchase price or construction
cost thereof or securing any Debt incurred prior to, at the time or within 180
days after, the acquisition of such property, shares of stock or Debt or the
completion of any such construction, whichever is later, for the purpose of
financing all or any part of the purchase price or construction cost thereof;
(3) Liens on any property to secure all or any part of the cost of development,
operation, construction, alteration, repair or improvement of all or any part of

the Company to a Restricted Subsidiary; (5) Liens securing indebtedness of a
corporation which becomes a successor of the Company in a transaction not
otherwise prohibited by this Agreement, provided that any such Lien was in
existence prior to the consummation of such

                                      -14-
<PAGE>

transaction, was not effected in contemplation of such transaction and does not,

compliance with the other provisions of this paragraph 6A; (6) Liens on property
of the Company or a Restricted Subsidiary in favor of governmental authorities
to secure partial, progress, advance or other payments or to secure any
indebtedness incurred for the purpose of financing all or any part of the
purchase price or the cost of construction of the property subject to such
Liens, or in favor of any trustee or mortgagee for the benefit of holders of
indebtedness of any such entity incurred for any such purpose; and (7) any
extension, renewal or replacement (or successive extensions, renewals or
replacements), in whole or in part, of any Lien referred to in the foregoing
clauses (1) to (6), inclusive, or of any Debt secured thereby, provided that
such extension, renewal or replacement Lien shall be limited to all or any part
of the same property that secured the Lien extended, renewed or replaced (plus
any improvements on such property) and shall secure no larger amount of Debt
than that existing at the time of such extension, renewal or replacement.

involving any Principal Property, the completion of construction and
commencement of full operation of which has occurred more than 180 days prior
thereto, unless (a) the Company or such Restricted Subsidiary could incur a Lien
on such property under the restrictions set forth in paragraph 6A in an amount
equal to the Attributable Debt of the Company or its Restricted Subsidiaries
with respect to the sale and leaseback transaction without equally and ratably
securing the Company Obligations or (b) the Company, within 180 days, applies to
the retirement of Funded Debt of the Company or its Restricted Subsidiaries the
greater of (i) the next proceeds of the sale or transfer of the Principal
Property so sold and leased back or (ii) the fair value of the Principal
Property so sold (as of the date of such sale or transfer) and leased back. The
foregoing restriction will not apply to any sale and leaseback transaction (x)
between the Company and a Restricted Subsidiary or between Restricted
Subsidiaries or (y) involving the taking back of a lease for a period of less
than three years. For purposes of this paragraph 6B, the determination of the
net proceeds of the sale or transfer of a Principal Property or the fair value
of the Principal Property so sold or transferred shall be as determined in good
faith by the Board of Directors.

other Person, unless:

          (1) the corporation formed by such consolidation or into which the
     Company is merged or the Person which acquires by conveyance or transfer,
     or which leases, the properties and assets of the Company substantially as
     an entirety shall be a corporation organized and existing under the laws of
     the United States of America, any State thereof or the District of Columbia
     and shall expressly assume, by an agreement supplemental hereto, executed
     and delivered to the holders of the Notes, in form satisfactory to the
     Required Holders, the due and punctual performance of the Company
     Obligations and the payment and performance eof every other covenant
     (including, without limitation, those in respect of the Company
     Obligations) of this Agreement on the part of the Company to be performed
     or observed;

          (2) immediately after giving effect to such transaction and treating
     any indebtedness which becomes an obligation of the Company or a Subsidiary
     as a result of such transaction as having been incurred by the Company or
     such Subsidiary at the time of such transaction, no Event of Default or
     Default or Purchase Event, and no event which, after notice or lapse of
     time or both, would become a Purchase Event, shall have happened and be
     continuing; and

          (3) The Company has delivered to the holders of the Notes an Officer's
     Certificate and an Opinion of Counsel, each stating that such
     consolidation, merger conveyance, transfer or lease and, if a supplemental
     agreement is required in connection with such transaction, such
     supplemental agreement comply with this paragraph 6C and that all

or lease is made shall succeed to, and be substituted for, and may exercise
every right and power of, the Company under this Agreement (including, without
limitation, those provided for in paragraph 8) with the same

                                      -16-
<PAGE>

effect as if such successor corporation had been named as the Company herein,
and thereafter, except in the case of a lease, the predecessor corporation shall
be relieved of all obligations and covenants under this Agreement.

     (c) If, upon any consolidation or merger of the Company or any Restricted
Subsidiary with or into any other corporation or corporations (whether or not an
Affiliate of the Company), or successive consolidations or mergers in which the
Company or any Restricted Subsidiary or their successors shall be a party or
parties, or upon any sale, conveyance or lease of the property of the Company or
any Restricted Subsidiary as an entirety or substantially as an entirety to any
other Person (whether or not an Affiliate of the Company), any Principal
Property of the Company or of any Restricted Subsidiary owned immediately prior
thereto would thereupon become subject to any Lien, the Company or any such
Restricted Subsidiary, prior to such consolidation, merger, sale, conveyance or
lease, shall by agreement supplemental hereto secure the due and punctual
payment of the Company Obligations (equally and ratably with any other
indebtedness of the Company then entitled thereto) by a direct Lien on all such
Principal Properties of the Company or any such Restricted Subsidiary, prior to
all Liens other than any theretofore existing thereon, unless such Lien would be

     7.  INCOME TAXATION.
         ---------------

     7A. ADDITIONAL PAYMENTS. In the event that at any time (whether before or
         -------------------
after payment of the Notes) a Gross-Up Event shall occur with respect to any
Indemnitee, the ESOP will pay to such Indemnitee as additional interest in
immediately available funds at the time or times specified in paragraph 7C:

     (a) an amount equal to the excess of

          (i) the amount of interest which would have been payable on the unpaid
     principal amount of such Indemnitee's Note during the Additional Payment
     Period if such Note had borne interest at a rate per annum equal to the
     Gross-Up Rate (or if the percentage of Interest on such Indemnitee's Note
     included in its Federal Gross Income shall exceed the Inclusion Rate but
     shall be less than 100%, the interest rate determined in accordance with
     paragraph 7D (determined by applying the Adjustment Fraction as if the
     Inclusion Rate had increased to the percentage of interest on such
     Indemnitee" Note included in its Federal Gross Income), in lieu of the
     Gross-Up Rate), over

                                      -17-
<PAGE>

          (ii) the amount of interest actually paid or payable under the terms
          of such Indemnitee's Note during the Additional Payment Period
          (excluding any additional interest on overdue amounts paid or payable
          as provided in the Notes); and

     (b) the sum of

          (i) the amount of any interest and of any penalties, additions to tax
     and additional amounts payable under the Code (such penalties, additions to
     tax and additional amounts being referred to as "Additions to Tax") which
     are deductible for Federal income tax purposes and are payable (or have
     been paid) to the United States by the Indemnitee as a consequence of the
     failure to include more than the Inclusion Rate of the interest referred to
     in paragraph 7A(a)(ii) in the Federal Gross Income of such Indemnitee, and

          (ii) an amount which, after giving effect to all taxes attributable to
     the inclusion of such amount in the gross income of such Indemnitee under
     the laws of any Federal, state or local governmental taxing authority (such
     taxes to be calculated at the maximum statutory rate, applicable to such
     Indemnitee during the relevant taxable period, after taking into account
     deductions and credits attributable to the imposition of Federal, state and
     local taxes), shall be equal to the amount of any interest or Additions to
     Tax which are not deductible for Federal income tax purposes and which are
     payable (or have been previously paid) to the United States by the
     Indemnitee as a consequence of the failure to include more than the
     inclusion Rate of the interest referred to in paragraph 7A(a)(ii) in the
     Federal Gross Income of such Indemnitee;

provided, however, that as to any Gross-Up event, no payment shall be required
--------  -------
pursuant to paragraph 7A(b) on account of any interest and Additions to Tax with
respect to periods after all amounts due under paragraph 7A have been paid with
respect to such Gross-Up Event.

     7B. SUPPLEMENTAL PAYMENTS.
         ---------------------

     (a) In the event that any time (whether before or after payment of the
Notes), in the reasonable opinion of an Indemnitee, which, at the request and
expense of the Company, is confirmed by an opinion of counsel to such
Indemnitee, a Change of Law shall occur with respect to such Indemnitee

                                      -18-
<PAGE>

which, in the reasonable opinion of such Indemnitee, results in any Tax
Disallowance, the ESOP shall pay to the Indemnitee within 30 days following the
receipt of written notice from the Indemnitee, in immediately available funds
amounts that shall be equal to the sum of (i) any tax, alternative minimum tax,
levy or other cost, including, but not limited to, penalties, additions to taxes
or interest related to any of the foregoing, related to the purchase, ownership,
or disposition of any Note that arises directly or indirectly, in whole or in
part, as a result of such Change of Law (all such taxes to be calculated
assuming rate in effect for the tax year or years in which the Tax Disallowance
occurs), plus (ii) an amount representing interest (at the Gross-up Rate) on any
such tax, levy or other cost listed in (i) above for the period (x) commencing
ten days after the Indemnitee shall have given notice to the Company of its
intention to pay, but in no event earlier than the date the Indemnitee shall
have paid, any such tax, levy or other cost listed in (i) above and (y) ending
on the date payment hereunder is received by the Indemnitee, plus (iii) an
amount which, after giving effect to all taxes attributable to the inclusion of
such amount in the taxable income of the Indemnitee for Federal and state tax
purposes, shall equal all taxes due on the payments set forth in (i), but only
to the extent such payments set forth in (i) are not items for which the
Indemnitee is allowed a tax deduction. Except as provided in 7(C)(b), the
determination of all amounts hereunder by the Indemnitee shall be conclusive and
binding on the Company absent manifest error.

     (b) Notwithstanding paragraph 7B(a), if the ESOP determines that any Change
of Law has occurred with respect to an Indemnitee which would result in a
liability of the ESOP to such Indemnitee pursuant to paragraph 7B(a), the ESOP
may, a its option, upon not more than 60 nor less than 30 days notice, cause the
terms of all Notes of all Series held by such Indemnitee to be adjusted in the
following manner on the date specified in such notice (the "Adjustment Date"):
(i) the interest rate on the Notes will be increased to the Gross-Up Rate
effective as of the Adjustment Date and (ii) the ESOP will have no liability for
payments that otherwise would be due under paragraphs 7A, 7B and 7D, except for
payments that may be due under paragraphs 7A, 7B and 7D with respect to periods
prior to the Adjustment Date. The ESOP will pay accrued interest on the Notes
through the date of adjustment on the Adjustment Date. At the request of such
Indemnitee, the ESOP will exchange the adjusted Notes for new Notes solely
reflecting the change to the interest rate.

                                      -19-
<PAGE>

     7C. PAYMENT DATES. (a) If the ESOP becomes obligated to make payments to
         -------------
any Indemnitee pursuant to paragraph 7A, the Indemnitee shall from time to time
notify the ESOP and the Company of the amount that is payable in respect of such
portion of the Additional Payment Period (i) as had elapsed prior to the
occurrence of a Gross-Up Event, which amount shall be due and payable (A) in the
case such notice is given prior to payment in full of the Notes, on the first
date thereafter on which any interest on the Notes is due and payable (or, if
later, 10 days after the date of such notice), or (B) in the case such notice is
given after payment in full of the Notes, within 10 days after the date of such
notice, and (ii) as had elapsed on and after the occurrence of a Gross-Up event,
which amount will be payable on each date thereafter on which any interest on
the Notes is due and payable (each notice under this clause (ii) shall be given
at least 10 days prior to such interest payment date); provided, however, that
if the Gross-Up Event occurs solely as a result of the occurrence of the event
described in clause (b)(i) of the definition of Gross-Up Event, and if neither a
Purchase Event nor Default has occurred and is continuing, the ESOP and the
Company may elect not to make any payments due under paragraph 7A during the
period of any contest under paragraph 7F, unless the Indemnitee makes a payment
(including reducing any available refund, offset or credit otherwise available)
of the increased Federal tax arising from the Gross-Up Event, in which event the
amount payable under paragraph 7A shall be paid by the ESOP to the Indemnitee
promptly upon its receipt of notice of such payment from the Indemnitee.

     (b) The computation of any amount payable under paragraph 7A, 7B, 7D or 7E
shall be made in good faith by the Indemnitee and shall be explained in writing
to the ESOP and the Company, but neither the ESOP nor the Company shall have any
right to examine the Indemnitee's Federal income tax returns or any other
returns, documents or records of the Indemnitee. At the Company's or the ESOP's
request and at the Company's expense, the Indemnitee will cause the Indemnitee's
independent auditors to review such computation and certify to the Company or
the ESOP, as the case may be, that such computation is accurate in all material
respects or shall certify as to the correct computation if such computation is
not accurate in all material respects.

     (c) If the ESOP shall fail to pay any amount payable under paragraphs 7A on
the due date pursuant to this paragraph 7C, the ESOP shall also pay, to the
extent lawful, interest on such unpaid amount at the rate payable on overdue
payments of principal on the Notes, as set forth therein.

                                      -20-
<PAGE>

     7D. INTEREST RATE ADJUSTMENT. In the event that, with respect to an
         ------------------------
Indemnitee at any time after the date hereof there is for any reason a change in
the Federal Tax Rate or the Inclusion Rate which is enacted after the date
hereof, then, in that event, the interest rate on the Notes of each series held
by such Indemnitee shall be automatically adjusted (but not higher than the
Gross-Up Rate nor lower than the Fully Tax Exempt Rate with respect to such
Notes), effective as of the effective date of change for each such change, to
the rate per annum determined by multiplying the original interest rate
applicable to the Notes of such series by the Adjustment Fraction. Such
Indemnitee shall determine the adjusted interest rate on its Notes in accordance
with the foregoing, subject to the procedures described in paragraph 7C(b). The
ESOP unconditionally promises to pay interest on such Notes from the effective
date of such change at the rate as so adjusted from time to time. If for any
reason (e.g., a retroactive effective date) the effective date of change for any
such change is prior to one or more payment dates for which payments were due
and payable on such Notes, and adjustments to payments are required under this
paragraph 7D, (i) the ESOP shall promptly upon demand by such Indemnitee pay the
amount by which interest computed at such rate or rates exceeds the amount of
interest actually theretofore paid by the ESOP on the Notes or (ii) the amount
by which the interest computed at such rate or rates is exceeded by the amount
of interested theretofore paid by the ESOP on the Notes shall be applied as an
offset against subsequent payments of interest and principal on the Notes.

     7E. REFUNDS. (a) If the ESOP or the Company shall make any payment to any
         -------
Indemnitee pursuant to paragraph 7A or 7B and such Indemnitee shall thereafter
receive a refund, offset or credit of federal tax for any taxable year to which
such payment related in respect of a claim that part of the interest on the
Notes to which such payment related was excludable from its Federal Gross Income
such Indemnitee shall pay to the ESOP or the Company, as the case may be, the
sum of:

          (i) an amount equal to the amount previously paid to such Indemnitee
     pursuant to paragraph 7A(a) or 7B with respect to all interest on such
     Notes for such taxable year to which such claim for refund, offset, or
     credit related (the "Disputed Interest") multiplied by a fraction (not to
     exceed one) the numerator of which is the amount of the refund or credit
     received of tax paid with respect to the Disputed Interest and the
     denominator of which is the amount of all tax paid by such Indemnitee with
     respect to such Disputed Interest; and

                                      -21-
<PAGE>

          (ii) the amount of any refunded, offset or credited interest or
     Additions to Tax that had been paid with respect to such Disputed Interest
     and with respect to which such Indemnitee had been paid with respect to
     such Disputed Interest and with respect to which such Indemnitee had been
     paid pursuant to paragraph 7A(b) or 7B (except to the extent already paid
     under clause (I))).

     (b) Other Adjustments. (i) If the ESOP or the Company shall make any
         -----------------
payment to an Indemnitee pursuant to paragraph 7B and if, in the Federal income
tax return of such Indemnitee or after any adjustment of such return, the amount
of the Tax Allowance or other amount by reference to which the amount of the
supplemental payments is determined differs form the amount used to compute the
amount of such payment, the ESOP or the Company, as the case may be, shall pay
to such Indemnitee promptly on written demand any additional amount computed
pursuant to paragraph 7B, and the Indemnitee shall promptly refund to the ESOP
or the Company, as the case may be, any excess amount paid pursuant to paragraph
7B, attributable to such difference.

     (ii) In the case of a Gross-Up Event occurring solely as a result of the
                           --------
failure to provide a Qualifying Opinion of Counsel, the Indemnitee shall be
treated as receiving a refund if and when it files a federal income tax return
excluding interest on the Indemnitee's Note, in an amount equal to the product
of the amount paid pursuant to paragraph 7A with respect to such Gross-Up Event
multiplied by a fraction (not to exceed 1), the numerator of which is the amount
of interest on the Indemnitee's Note excluded on the return, and the denominator
of which is the amount of the interest on the Indemnitee's Note that would be
excludable assuming application of Section 133 of the Code.

     7F. CONTEST OF DISALLOWANCE OF SECTION 133 EXCLUSION.
         ------------------------------------------------

     (a) Notice. If an Indemnitee receives and IRS Notice asserting a claim
         ------
which, if successful, could result in a Gross-Up Event (an "Exclusion Claim"),
the Indemnitee agrees to notify the ESOP and the Company in writing, as promptly
as possible, of such Exclusion Claim and provide the ESOP and the Company with
any relevant information relating to such Exclusion Claim that may be available
to the Indemnitee. The Company will notify all other Indemnitees of such
Exclusion Claim.

     (b) Contest. The Indemnitee further agrees to contest any Exclusion Claim
         -------
with diligence and in good faith, including appealing any adverse administrative
or judicial determination and seeking a refund with respect to any Exclusion
Claim if (in provided, however, that:
             --------  -------

                                      -22-
<PAGE>

          (i) within 30 days after notice by the Indemnitee to the ESOP and the
     Company of such Exclusion Claim, the ESOP or the Company shall request that
     such Exclusion Claim be contested;

          (ii) the amount payable to the Indemnitee under paragraph 7A with
     respect to such Exclusion Claim would exceed $50,000;

          (iii) prior to the Indemnitee's taking any such requested action
     (including appealing any adverse decision), the ESOP or the Company (at the
     expense of either the ESOP or the Company and upon the written request of
     the Indemnitee) shall provide the Indemnitee with an opinion, reasonably
     satisfactory to the Indemnitee, of nationally recognized counsel,
     independent of the ESOP and the Company and reasonably satisfactory to the
     Indemnitee to the effect that there exists a substantial authority (within
     the meaning of Section 6661 of the Code) for contesting such Exclusion
     Claim;

          (iv) the ESOP or the Company shall from time to time pay to the
     Indemnitee within 30 days after receipt by the ESOP and the Company of an
     itemized written demand therefor and explanation thereof an amount
     sufficient to reimburse the Indemnitee for all out-of-pocket expenses that
     the Indemnitee has incurred in connection with contesting or defending such
     Exclusion Claim or any appeal thereof, including, without limitation,
     expert witness, attorneys' and accountants' fees and disbursements; and

          (v) the Indemnitee may, at any time, settle, compromise or otherwise
     terminate any contest with the consent of the ESOP and the Company, which
     consent shall not be unreasonably withheld.

     (c) Control over Contest. Sole control over the conduct of any contest
         --------------------
under subparagraph (b) of this paragraph 7F shall be vested in the Indemnitee,
but the Indemnitee shall consult with the ESOP, the Company and their counsel
regarding all aspects of the contest, and shall consider and act on (or refrain
from acting on) in good faith any recommendations of the ESOP, the Company, and
their counsel as to conduct of the contest. The right of the Indemnitee to
control the conduct of any contest shall not be construed to relieve the
Indemnitee of its obligation to contest any Exclusion Claim in accordance with
paragraph 7F(b).

                                      -23-
<PAGE>

     (d) Segregation and Settlement.
         --------------------------

     (i) The Indemnitee shall use its best efforts to segregate the Exclusion
Claim triggering a payment under paragraph 7A from other tax issues it may be
protesting or litigating with the IRS; provided, however, that the Indemnitee
                                       --------  -------
shall not be required to take any action that would in good faith and in its
sole discretion, impair the Indemnitee's ability to settle with the IRS with
respect to such other issues or materially affect the terms of any such
settlement.

     (ii) If the Indemnitee has made such best efforts as required by clause (i)
of this paragraph (d) but has not segregated such Exclusion Claim, then,
notwithstanding anything to the contrary contained in subparagraph (a), (b) or
(c) of this paragraph 7F, the Indemnitee may in its sole discretion settle or
compromise such Exclusion Claim, provided the Indemnitee gives the ESOP and the
Company notice of its intention to settle or compromise such Exclusion Claim.
If, after receiving the notice referred to in the preceding sentence and within
45 days of an agreement between the Company and the Indemnitee on the identity
of counsel, the Company provides the Indemnitee with an opinion, reasonably
satisfactory to the Indemnitee, of nationally recognized counsel, independent of
the ESOP and the Company and reasonably satisfactory to the Indemnitee, that it
is highly probable that the Indemnitee would prevail in litigation with respect
to such Exclusion Claim, then, if the Indemnitee settles or compromises such
Exclusion Claim, to the extent payment was made by the ESOP or the Company under
paragraph 7A as a result of a Gross-Up Event arising solely from such Exclusion
Claim, the Indemnitee shall be deemed to have received a refund in the amount of
such payment, and shall immediately return such amount to the ESOP or the
Company; to the extent payment was not made, such Gross-Up Event shall be deemed
not to have occurred. Alternatively, if the Company provides the Indemnitee with
an opinion, reasonably satisfactory to the Indemnitee, of nationally recognized
counsel, independent of the ESOP and the Company and reasonably satisfactory to
the Indemnitee, that it is more likely than not that the Indemnitee would
prevail in litigation with respect to such Exclusion Claim, then, if the
Indemnitee settles or compromises such Exclusion Claim, if the amount paid by
the ESOP or the Company exceeds 50% of the amount payable pursuant to paragraph
7A as result of a Gross-Up Event arising solely from such Exclusion Claim, the
Indemnitee shall pay such excess to the ESOP or the Company, as appropriate; and
if 50% of the amount payable pursuant to

                                      -24-
<PAGE>

paragraph 7A as a result of such Gross-Up Event exceeds the amount paid by the
ESOP or the Company, the ESOP or the Company, as the case may be, shall pay the
amount of such excess to the Indemnitee in complete accord and satisfaction of
its obligations as to such issue under paragraph 7A.

     7G. REQUEST FOR QUALIFYING OPINION OF COUNSEL. If any Indemnitee
         -----------------------------------------
determines, in good faith after consultation with independent nationally
recognized counsel, that there is a reasonable likelihood for any reason
whatsoever that any Qualified Holder will be required to include more than that
percentage of the interest on the Notes which is equal to the Inclusion Rate in
its Federal Gross Income, such Indemnitee shall be entitled to request, at the
Company's expense, a Qualifying Opinion of counsel with respect to interest on
the Notes for a period commencing with the date of issuance of the Notes and
continuing through the date of such request or for any lesser period specified
in such Indemnitee's request. If such a request is made, such Indemnitee shall
supply the counsel rendering such opinion with such information, reasonably
available to such Indemnitee, as may be reasonably requested by such counsel in
order for it to form a basis for rendering the opinion requested.

     8. COMPANY GUARANTEE AND PURCHAS OBLIGATION
        ----------------------------------------

     8A. GUARANTEE BY THE COMPANY. (a) Obligations Guaranteed. The Company, in
         ------------------------      ----------------------
consideration of the execution and delivery of this Agreement, hereby
unconditionally and irrevocably guarantees to you (together with your successors
and assigns, hereinafter referred to as the "Purchaser"), and to the holders
from time to time of the Notes, the due and punctual payment of the principal
of, premium, if any (including the Yield-Maintenance Premium), and interest on
the Notes (including post-petition interest in the event of a bankruptcy or
similar proceeding) when and as the same shall become due and payable, whether
at the maturity thereof, by acceleration, by notice of prepayment or otherwise,
according to the terms thereof and of this Agreement, and the due and punctual
payment of any other amounts owing to the Purchaser and to such holders under or
in respect of the Notes and all other payment obligations of the ESOP hereunder
(including, without limitation, amounts payable by the ESOP pursuant to
paragraph 7), whether absolute or contingent, liquidated of unliquidated. In the
absence of the due observance and performance by the ESOP of any of its other
obligations, undertakings and conditions contained in this Agreement, the
Company shall use its best efforts, to the extent practicable, to provide
reasonably equivalent performance intended to

                                      -25-
<PAGE>

achieve comparable results. If the ESOP shall not punctually pay any such
principal, premium (including, without limitation, Yield-Maintenance Premium),
interest or other amounts (regardless of whether the holders of the Notes have
recourse against the ESOP), the Company shall make such payment forthwith
thereafter. If the Purchaser or any of the holders of the Notes shall have the
right to declare any or all of the Notes due and payable (or any such right
shall be limited by operation of the last sentence of paragraph 9A or
otherwise), and acceleration of the payment of such Notes is stayed, enjoined or
otherwise prevented for any reason, including, without limitation, because of
any bankruptcy proceeding or the provisions of Treasury Regulation section
54.4975-7 or 54.4975-11, the Company, upon demand therefor, shall pay to the
Purchaser and each holder of Notes the sums which would have been due to the
Purchaser and such holders under this Agreement if such acceleration had
occurred, all as permitted by applicable law.

     (b) Obligations Unconditional. The Company agrees that its obligations
         -------------------------
hereunder are absolute and unconditional, irrespective of the validity,
regularity or enforceability of or any change in or amendment to any Note or
this Agreement, the institution or absence of any action to enforce the same,
the waiver or consent by the Purchaser or the holder of any Note with respect to
the provisions thereof, the obtaining of any judgement against the ESOP or any
action to enforce the same, the inability to recover from the ESOP because of
any statute of limitations, laches or otherwise or any other circumstance which
might otherwise constitute a legal or equitable discharge of or a defense to a
guarantor, and that the provisions of this paragraph 8 constitute a guarantee of
payment and not of collectibility.

     (c) Waivers and Agreements. The Company hereby unconditionally: (i) waives
         ----------------------
notice of acceptance hereof, of any action taken or omitted in reliance hereon
and of any defaults in respect of the Notes or in the payment of any other
amounts due in respect thereof, diligence, protest, presentment, filing of
claims with a court in the event of the bankruptcy of the ESOP (subject to such
filings as may be necessary to protect rights of subrogation, but only at the
written instance and expense of the Company), any right to require a proceeding
first against the ESOP or that the ESOP be joined in any proceeding against the
Company, any marshalling of assets of the Company or the ESOP, any notice of
default with respect to any of the Notes or this Agreement or any other act or
omission or thing or delay to do any other act or thing which might in any
manner or to any extent vary the risk of the Company or which might otherwise
operate as a discharge of the

                                      -26-
<PAGE>

Company; (ii) agrees that this guarantee shall remain in full force and effect
without regard to, and shall not be affected or impaired by, any invalidity,
irregularity or unenforceability in whole or in part or any of the Notes or this
Agreement or any of the limitations of liability or payment conditions
thereunder which may now or hereafter be caused or imposed in any manner
whatsoever; (iii) agrees that this guarantee shall not be subject to any
counterclaim (other than those which are compulsory in nature), set-off,
deduction or defense based upon any claim the Company may have against the ESOP
or any holder of the Notes hereunder or otherwise; and (iv) agrees that this
guarantee shall be discharged only by complete performance of the undertakings
in this paragraph 8. Nothing herein is intended to impair any rights of the
Company to enforce any rights it may have against any Person by way of a
separate proceeding or action.

     (d) Obligations Unimpaired. The Company authorizes the Purchaser and the
         ----------------------
holders of the Notes, without notice or demand to the Company and without
affecting its liability hereunder, from time to time (I) to exercise or refrain
from exercising any rights against the ESOP or others; and (ii) to apply any
sums, by whomsoever paid or however realized, to the payment of the principal
of, premium, if any (including the Yield-Maintenance Premium), and interest on
the Notes and any other obligation hereunder. The Company waives any right to
require the Purchaser and the holders of the Notes to proceed against the ESOP
or any other Person or to pursue any other remedy available to the Purchaser or
to such holders.

     (e) Subrogation. In the event the ESOP fails to observe or perform any of
         -----------
its obligations or undertakings under this Agreement (an "ESOP Default"), the
Company will be subrogated and succeed to the rights of the Purchaser and the
holders of the Notes which may be asserted against the ESOP by the Purchaser or
such holders as a result of any such ESOP Default upon payment or performance of
such obligations or undertakings; provided, however, that the Company will not
                                  --------  -------
exercise any rights which it may have acquired by way of subrogation under this
Agreement, by any payment made hereunder or otherwise, or accept any payment on
account of such subrogation rights, unless and until all of the obligations,
undertakings or conditions then and thereafter to be performed or observed by
the ESOP pursuant to the Notes and this Agreement shall have been performed,
observed or paid in full by the ESOP or the Company, and the Company's rights of
subrogation hereunder are expressly subordinate to the rights of the Purchaser
and holders of the Notes arising out of the Agreements. In the event that the
Company receives any payment on account of such subrogation rights, it shall
promptly apply

                                      -27-
<PAGE>

such payment to the extent of its obligations hereunder. In the event that the
Company pays or causes to be paid all amounts due under any of the Notes, the
Purchaser or holder will assign and transfer such Notes to the Company or its
designee. In no event shall such subrogation grant to the Company any right or
power with respect to the ESOP which it is forbidden to exercise pursuant to
ERISA or the Code or the regulations thereunder, including but not limited to
Treasury Regulations sections 54.4975-7 and 54.4975-11.

     (f) Rescission of Payment. This guarantee shall continue to be effective or
         ---------------------
be reinstated, as the case may be, if at any time payment, or a part thereof, of
the principal of, premium (including, without limitation, the Yield-Maintenance
Premium), if any, or interest on any of the Notes or of any other obligations
guaranteed hereby is rescinded or must otherwise be restored or returned by the
Purchaser or any holder of Notes upon the insolvency, bankruptcy or
reorganization of the ESOP, or otherwise, all as though such payment has not
been made.

     (g) Election to Perform Obligations. The Company may at any time elect to
         -------------------------------
pay or otherwise perform any obligation of the ESOP under this Agreement or in
respect of the Notes, which shall operate as a discharge and release of the ESOP
from such obligation to the Purchasers or any subsequent holders of the Notes
(but not to the Company as subrogee or as a successor Noteholder), provided that
no such election shall release the ESOP from any of its other obligations
                                                              -----------
hereunder and under the Notes.

     8B. PURCHASES OF NOTES BY THE COMPANY. (a) At any time after the occurrence
         ---------------------------------
of a Purchase Event and prior to the expiration of the later of (x) 90 days
after receipt of an Event Notice relating thereto and (y) 15 days after receipt
of an Other Holder Notice (as defined below), any holder of a Note may deliver a
notice to the Company (x) stating that it is electing to exercise its right to
require the purchase by the Company pursuant to this paragraph 8B of the Notes
then held by it (a "Purchase Notice") and (y) specifying the date on which such
purchase shall occur (which date shall not be less than 25 nor more than 35 days
after the date on which such holder shall have delivered such Purchase Notice to
the Company), and in any such event the Company, on such specified date, shall
purchase or cause to be purchased the Note or Notes then held by such holder,
without recourse, representation or warranty (other than as to the holder's full
right, title and interest, free of any adverse claim, in such Note or Notes),
and such holder shall sell such Note or Notes to or at the direction of the
Company at a price, payable in immediately available funds by

                                      -28-
<PAGE>

wire transfer to the account specified pursuant to paragraph 14A or to such
other account as may be specified in such notice, equal to the then outstanding
principal amount thereof, together with interest accrued on such principal
amount to the date of purchase, plus a premium equal to the Yield-Maintenance
Premium, if any, plus any amounts then due under Section 7 with respect to each
Note purchased. Promptly, and in any event within five days following its
receipt thereof, the Company will deliver to each holder of a Note a copy of any
Purchase Notice received by its pursuant to subparagraph (a) of paragraph 8B of
this Agreement or the Other Agreements (an "Other Holder Notice"). The Company
shall comply with all applicable laws (including, without limitation, securities
laws) in connection with its purchase of Notes hereunder and any related
transactions.

     (b) If either or both of Moody's or Standard & Poor's is not providing
public ratings of the Unsupported Company Debt, the Company may (subject to the
approval of the Required Holder(s)), and, at the request of the Required
Holder(s), shall substitute another rating agency or other rating agencies of
national reputation for Moody's and/or Standard & Poor's for the purpose of
determining, by reference to the public ratings of two such rating agencies
(which shall include Moody's or Standard & Poor's if one of them is providing
public ratings of the Unsupported Company Debt), whether the Company shall be
obligated pursuant to subparagraph (a) of this paragraph 8B to purchase such
holder's Note or Notes as a result of a Purchase Event. If no rating agency of
national reputation satisfactory to the Required Holder(s) or only one of such
rating agency is providing public ratings of the Unsupported Company Debt, any
holder of a Note may request that the Company obtain from either or both, as
appropriate, of Moody's and Standard & Poor's a private credit rating for the
Unsupported Company Debt for the purpose of determining, by reference to the
ratings of either or both as appropriate, of such rating agencies, whether the
Company shall be obligated pursuant to subparagraph (a) of this paragraph 8B to
purchase such holder's Note or Notes. Upon receipt of any such request, the
Company shall promptly, and in any event within 10 days after receiving such
request, either or both, as appropriate notify each other holder of a Note of
such request and use its best efforts to obtain as promptly as practicable from
either or both, as appropriate, of Moody's and Standard & Poor's (or, if either
of them declines to provide a private credit rating, the other of them and one
rating agency of national reputation, and if both of them so decline, two rating
agencies of national reputation, in each case approved by the Required
Holder(s)) a private credit rating for such purpose. If the Company does not
have any Unsupported Company Debt, the determination of whether the Company
shall be obligated pursuant to subparagraph (a) of this paragraph 8B to purchase
any holder's Note or Notes shall be

                                      -29-
<PAGE>

made as aforesaid, but by reference to a credit rating of the Notes instead of
Unsupported Company Debt. If the Company is required pursuant to this
subparagraph (b) of this paragraph 8B to seek a private credit rating and fails
to obtain such private credit rating within 60 days of any holder's request
therefor, such rating shall be deemed to be less than Baa3 or BBB- (or any
comparable rating then in existence). In the event another rating agency of
national reputation is substituted for Moody's or Standard & Poor's, such
determination shall be made by reference to the rating of such substituted
agency that it most nearly comparable to Baa3 of Moody's and BBB- of Standard &
Poor's (or, in either case, the comparable ratings then in existence).
Suspension of a rating by a rating agency shall be deemed to have the effect of
such agency's providing no rating.

     (c) The Company covenants that it will deliver to each holder of a Note
promptly, and in any event within 10 days following the occurrence thereof, (x)
a notice of any change in the credit rating (whether public or private), or any
cessation of the credit rating, of the Unsupported Company Debt by Moody's or
Standard & Poor's, together, in the case of any such change, with a statement of
the date of such occurrence and a reasonably detailed description of the facts
and circumstances underlying such occurrence know to it, and (y) a notice of the
occurrence of a Purchase Event, together with a statement of the date of
occurrence of such Purchase Event and a reasonably detailed description of the
facts and circumstances underlying such occurrence know to it, and which states
that the Company is obligated, upon receipt of a Purchase Notice described in
subparagraph (a) of this paragraph 8B, to purchase Notes pursuant to
subparagraph (a) of this paragraph 8B (an "Event Notice").

     9. EVENTS OF DEFAULT.
        -----------------

     9A. DEFAULT; ACCELERATION. If any of the following events shall occur and
         ---------------------
be continuing for any reason whatsoever (and whether such occurrence shall be
voluntary or involuntary or come about or be effected by operation of law or
otherwise):

          (i) default in the payment of any principal (including any Required
     Installment Payment) of or Yield-Maintenance Premium on any Note when the

     otherwise as herein provided; default in the discharge by the Company of
     its obligations to purchase Notes pursuant to paragraph 8B when required by
     the provisions of said paragraph; or default in the payment of any interest
     on any Note when the same shall become due and such default shall continue
     for more than 10 days; or

<PAGE>

          (ii) the Company states or otherwise claims in writing that any of its
     obligations under paragraph 8 is not enforceable in accordance with its
     terms; or

          (iii) default in the performance, or breach, of any covenant of the
     Company or the ESOP in this Agreement (other than a covenant a default in
     whose performance or whose breach is elsewhere in this paragraph 9A
     specifically dealt with), and continuance of such default or breach for a
     period of 30 days after the chief executive officer, chief operating
     officer, principal financial officer, principal accounting officer,
     treasurer or any other executive officer of the Company has obtained actual
     knowledge of such default or breach; or

          (iv) any representation or warranty made by the Company or the ESOP
     herein or in any writing furnished pursuant to the requirements of this
     Agreement shall be false in any material respect on the date as of which
     made; or

     benefit of creditors or is generally not paying its debts as such debts
     become due; or

          (vi) any decree or order for relief in respect of the Company or any
     Restricted Subsidiary is entered under any bankruptcy, reorganization,
     compromise, arrangement, insolvency, readjustment of debt, dissolution or
     liquidation or similar law, whether now or hereafter in effect (herein
     called the "Bankruptcy Law"), of any jurisdiction; or

          (vii) the Company or any Restricted Subsidiary petitions or applies to
     any tribunal for, or consents to, the appointment of, or taking possession
     by, a trustee, receiver, custodian, liquidator or similar official of the
     Company or any Restricted Subsidiary, or commences a voluntary case under
     the Bankruptcy Law of the United States or any proceedings (other than
     proceedings for the voluntary liquidation and dissolution of a Restricted
     Subsidiary) relating to the Company or any Restricted Subsidiary under the
     Bankruptcy Law of any other jurisdiction; or

          (viii) any petition or application referred to in clause (vii) above
     is filed, or any such proceedings are commenced, against the Company or any
     Restricted Subsidiary and the Company or such Restricted Subsidiary, by any
     corporate act, consents thereto or acquiesces therein, or

                                      -31-
<PAGE>

     an order, judgement or decree is entered appointing any such trustee,
     receiver, custodian, liquidator or similar official, or approving the
     petition in any such proceedings, and such order, judgment or decree
     remains unstayed and in effect for more than 90 days; or

          (ix) any order, judgment or decree is entered in any proceedings
     against the Company or any Restricted Subsidiary decreeing the dissolution
     of the Company or such Restricted Subsidiary and such order, judgment or
     decree remains unstayed and in effect for more than 60 days; or

          (x) any order, judgment or decree is entered in any proceeding against
     the Company or any Restricted Subsidiary decreeing a split-up of the
     Company or such Restricted Subsidiary which requires the divestiture of
     assets representing a substantial part, or the divestiture of the stock of
     a Restricted Subsidiary whose assets represent a substantial part, of the
     consolidated assets of the Company and its Subsidiaries (determined in
     accordance with generally accepted accounting principles) or which requires
     the divestiture of assets, or stock of a Restricted Subsidiary, which shall
     have contributed a substantial part of the consolidated net income of the
     Company and its Subsidiaries (determined in accordance with generally
     accepted accounting principles) for any of the three fiscal years then most
     recently ended, and such order, judgment or decree remains unstayed and in
     effect for more than 60 days (for the purpose of this clause (x),
     substantial shall mean 25% of Consolidated Net Tangible Assets); or

          (xi) any "reportable event" as such term is defined in section 4043 of
     ERISA occurs in connection with any ERISA Plan or trust created thereunder
     for which the thirty-day notice requirement has not been waived under
     applicable regulations, or an event occurs requiring the Company or any
     ERISA Affiliate to provide security to an ERISA Plan under section
     401(a)(29) of the Code; any "prohibited transaction" occurs, as such term
     is defined in section 4975 of the Code or in section 406 of ERISA, in
     connection with any ERISA Plan or any trust created thereunder, for which
     there is no exemption; any notice of intent to terminate an ERISA Plan is
     filed under Title IV of ERISA by the Company or any ERISA Affiliate, any

<PAGE>

     Plan against the Company or any Code Affiliate to enforce section 515 of
     ERISA and such proceeding shall not have been dismissed within 30 days
     thereafter; the Company or a Code Affiliate fails to make a required
     installment under section 412(m) of the Code or to pay any amount or
     amounts which it shall have become liable to pay to the PBGC or to an ERISA
     Plan under Title IV of ERISA on or before the due date; any application is
     filed by the Company or a Code Affiliate for a waiver of the minimum
     funding standard under section 412 of the Code or section 302 of ERISA; or
     any "reorganization" (as defined in section 418 of the Code or Title IV of
     ERISA) of any plan which is a Multiemployer Plan occurs; and each such
     instance individually, or any two or more such instances in the aggregate,
     would, in the reasonable judgment of the Required Holders, more likely than
     not result in liability of the Company or any Code Affiliate or ERISA
     Affiliate to the IRS, the PBGC, the United States Department of Labor or an
     ERISA Plan in an aggregate amount exceeding $20,000,000; or

          (xii) any order, judgment or decree is entered in any proceeding by a
     court of competent jurisdiction decreeing that the Plan, the ESOP or the
     ESOP Transaction has not been properly established or consummated, as the
     case may be (other than as specified in clause (ii) of the definition of
     Purchase Event), in any material respect, and such order, judgment or
     decree remains unstayed and in effect for more than 60 days and no appeal
     is filed by the Company or the ESOP therefrom within 60 days of the time
     such order, judgment or decree first becomes appealable; or

          (xiii) the Company or any Subsidiary defaults in any payment of
     principal of or interest on any other obligation for money borrowed (or any
     capitalized lease obligation, any obligation under a conditional sale or
     other title retention agreement, any obligation issued or assumed as full
     or partial payment for property whether or not secured by a purchase money
     mortgage or any obligation under notes payable or drafts accepted
     representing extension of credit), other than the Notes, beyond any period
     of grace provided with respect thereto, or the Company or any Subsidiary
     fails to perform or observe any other agreement, term or condition
     contained in any agreement (other than the Other Agreements) under which
     any such obligation is created (or if any other event thereunder or under
     any such agreement shall occur and be continuing) and the effect of such
     failure or other event is to cause (without any action by or on behalf of
     the holder or holders of such obligation), or as a result thereof the
     holder or holders of such obligation (or a trustee on behalf of such holder

                                      -33-
<PAGE>

     or holders) shall have caused, such obligation to become due prior to any
     stated maturity; provided that the aggregate amount of all obligations as
     to which such a payment default shall occur and be continuing or such a
     failure or other event causing or resulting in acceleration shall occur and
     be continuing exceeds $20,000,000;

then (a) if such event is an Event of Default specified in clause (vi), (vii) or
(viii) of this paragraph 9A with respect to the Company, all of the Notes at the
time outstanding shall automatically become immediately due and payable at the
principal amount thereof together with interest accrued thereon, without
presentment, demand, protest or notice of any kind, all of which are hereby
waived by the Company and the ESOP, and (b) if such event is an Event of Default
specified in clause (i) of this paragraph 9A the holder or holders of at least
25% of the aggregate principal amount of the Notes at the time outstanding, and
if such event is an Event of Default specified in clause (ii), (iii), (iv), (v),
(ix), (x), (xi), (xii) or (xiii) of this paragraph 9A the holder or holders of
at least 50% of the aggregate principal amount of the Notes at the time
outstanding, may at its or their option, by notice in writing to the Company and
the ESOP, declare all of the Notes to be, and all of the Notes shall thereupon
be and become (except that, if such event is an Event of Default specified in
clause (i) of this paragraph 9A with respect to any Note, the holder of such
Note may at its option by notice in writing to the Company and the ESOP declare
such Note to be, and such Note shall thereupon be and become) immediately due
and payable at the principal amount thereof together with interest accrued
thereon and the Yield-Maintenance Premium, if any, with respect thereto without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Company and the ESOP, provided that the Yield-Maintenance
                                           --------
Premium, if any, with respect to each Note shall be due and payable upon such
declaration only if (x) such event is an Event of Default specified in any of
clauses (i) to (v), inclusive, and clauses (xi), (xii) and (xiii) of this
paragraph 9A, (y) the holder or holders making such declaration shall have given
to the Company and the ESOP, at least 10 Business Days before such declaration,
written notice stating its or their intention so to declare the Notes to be
immediately due and payable and identifying one or more such Events of Default
whose occurrence on or before the date of such notice permits such declaration
and (z) one of more of the Events of Default so identified shall be continuing
at the time of such declaration. Nothing in this Agreement shall permit (i) a
transfer of assets of the ESOP to any Person in excess of the amount permitted
under Treasury Regulation ss. 54.4975-7(b) (5) or (6) or (ii) if a holder of any
Note is a disqualified person within the meaning

                                      -34-
<PAGE>

of section 4975 of the Code or the Regulations thereunder, the transfer of
assets of the ESOP to such holder except upon the failure of the ESOP to make
payment of regularly scheduled payments of principal of and interest on such
Notes, and then only to the extent of such failure.

     9B. OTHER REMEDIES. If any Event of Default or Default shall occur and be
         --------------
continuing, the holder of any Note may proceed to protect and enforce its rights
under this Agreement and such Note by exercising such remedies as are available
to such holder in respect thereof under applicable law, either by suit in equity
or by action at law, or both, whether for specific performance of any covenant
or other agreement contained in this Agreement or in aid of the exercise of any
power granted in this Agreement. No remedy conferred in this Agreement upon you
or any other holder of any Note is intended to be exclusive of any other remedy,
and each and every such remedy shall be cumulative and shall be in addition to
every other remedy conferred herein or now or hereafter existing at law or in
equity or by statue or otherwise.

     9C. RESCISSION OF ACCELERATION. At any time after any declaration of
         --------------------------
acceleration of any of the Notes shall have been made pursuant to paragraph 9A
by any holder or holders of the Notes and before a judgment or decree for the
payment of money due has been obtained by such holder or holders, the holder or
holders of at least 50% of the aggregate principal account of the Notes at the
time outstanding may, by written notice to the Company and the ESOP and to the
other holders of the Notes, rescind and annul such declaration and its
consequences, provided that (i) the principal of and interest on the Notes which
              --------
shall have become due otherwise than by such declaration of acceleration shall
have been duly paid and (ii) all Events of Default, other than the nonpayment of
principal of and interest on the Note which have become due solely by any such
declaration of acceleration, shall have been cured or expressly waived by such
holder or holders of not less than 50% of the aggregate principal amount of the
Notes at the time outstanding; provided further, however, that (x) no waiver
                               -------- -------  -------
referred to in clause (ii) above in respect of any matter referred to in the
proviso contained in the first sentence of paragraph 14C(a) shall be effective
without the consent of each holder of Notes affected by such waiver and (y) no
declaration pursuant to the parenthetical clause contained in clause (b) of the
last paragraph of paragraph 9A may be rescinded or annulled except by the holder
of Notes that made such declaration. No rescission or annulment referred to
above shall affect any subsequent Default or any right, power or remedy arising
out of such subsequent Default.

         ------------------------------
paragraphs 10G, 10I, 10N, and 100, the ESOP, as to the ESOP, and, in the case of
paragraph 100, the Trustee, as to the Trustee, represent and warrant that:

     10A. ORGANIZATION; CORPORATE AUTHORITY. The Company and each of its
          ---------------------------------
Restricted Subsidiaries are corporations duly organized and validly existing in
good standing under the laws of their respective states of incorporation and
have all requisite power, and have all material governmental licenses,
authorizations, consents and approvals, necessary to own their assets and carry
on their business as now being conducted, except where the failure to have such
power, licenses, authorizations, consents and approvals would not, individually
or in the aggregate, have a material adverse effect on the business, properties,
financial condition or results of operations of the Company and its Subsidiaries
taken as a whole. The Company and each of its Restricted Subsidiaries are
qualified to do business in all jurisdictions in which the nature of the
business conducted by them makes such qualification necessary and where failure
to do so would have a material adverse effect on the business, property,
financial condition or results of operations of the Company and its Subsidiaries
taken as a whole. The execution, delivery and performance of this Agreement and
the Plan Documents, and compliance with the provisions hereof and the
consummation of any other transactions contemplated hereby and by the Plan
Documents, are within the corporate power of the Company, have been duly
authorized by all necessary corporate action and are valid obligations of the
Company, legally binding upon and enforceable against the Company in accordance
with their respective terms.

     10B. FINANCIAL STATEMENTS; SEC REPORTS. The Company has furnished you with

contain an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading. There is no fact peculiar to the
Company which materially adversely affects or in the future would reasonably be

the business, properties, financial condition or results of operations of the
Company and its Subsidiaries taken as a whole which has not been set forth in
this Agreement or in the Disclosure Documents. Since December 31, 1988, there
has not been any material adverse change, or any development which the Company

or thereof, and any such proposed modifications, consents, amendments or waivers
(whether or not the same become affective), including without limitation costs
and expenses incurred in any bankruptcy case, and your costs incurred in
obtaining a PPN number from a rating agency in connection with your purchase of
Notes hereunder. The Company further agrees to indemnify and save harmless you
and any Transferee and each of your and any Transferee's officers, directors,
employees and agents (each herein called an "indemnified person") from and
against any and all actions, causes of action, suits, losses, liabilities and
damages, and expenses (including, without limitation, attorneys' fees and
disbursements provided, in any related series of actions involving different
Persons but with common interests and with no conflicting interest, only one
counsel's fees and disbursements shall be so reimbursed) in connection therewith
payable to any third party (herein called the "indemnified liabilities")
incurred by any indemnified person as a result of, or arising out of, or
relating to any of the transactions contemplated hereby, except for any
indemnified liabilities arising on account of the gross negligence or willful
misconduct of such indemnified person provided that, if and to the extent the
Company's agreement to indemnify may be unenforceable for any reason, the
Company shall make the maximum contribution to the payment and satisfaction of
each of the indemnified liabilities which shall be permissible under applicable
law.

     14C. CONSENT TO AMENDMENTS. (a) this Agreement may be amended with the
          ---------------------
consent of both the Company and the ESOP, and with such consent the Company or
the ESOP, as the case may be, may take any action herein prohibited, or omit to
perform any act herein required to be performed by it, but in any of the
foregoing cases only if there shall have been obtained the written consent to
                ----
such amendment, action or omission to act of the Required Holders, provided,
                                                                   --------
however, that, without the written consent of the holder or holders of all Notes
-------
at the time outstanding, no amendment to this Agreement shall change the
maturity of any Note or the right of any holder of a Note to accelerate such
Note pursuant to paragraph 9A, or change the principal of, or the rate or time
of payment of interest or any premium payable with respect to any Note, or
change any of the provisions of paragraph 7 or 8, or affect the time, amount or
allocation of any Required Installment Payments, or change any of the provisions
of paragraph 4, or change any of the definitions contained in paragraph 12 that
are used in paragraph 4, 7, or 8, or reduce the proportion of the principal
amount of the Notes required with respect to any consent, waiver or rescission.
Each holder of a Note at the time or thereafter outstanding shall be bound by
any consent authorized by this paragraph 14C, whether or not such Note shall
have been

                                      -59-
<PAGE>

marked to indicate such consent, but any Notes issued thereafter may bear a
notation referring to any such consent. No course of dealing between the ESOP or
the Company and any holder of a Note nor any delay in exercising any rights
hereunder or under any Note shall operate as a waiver of any rights of such
holder of a Note. As used herein and in the Notes, the term "this Agreement" or
references thereto shall mean this Agreement as it may from time to time be
amended or supplemented.

     (b) Neither the ESOP nor the Company will solicit, request or negotiate for
or with respect to any proposed waiver or amendment of any of the provisions of
this Agreement or the Notes unless each holder of Notes (irrespective of the
amount of Notes then held by it) shall be informed thereof by the ESOP of the
Company, as the case may be, and shall be afforded an opportunity of considering
the same and shall be supplied by the ESOP or the Company, as the case may be,
with sufficient information to enable it to make an informed decision with
respect thereto. Executed or true and correct copies of any waiver or consent
effected pursuant to the provisions of this Agreement shall be delivered by the
ESOP or the Company, as the case may be, to each holder of Notes forthwith
following the date on which the same shall have been executed and delivered by
the holder or holders of the requisite percentage of outstanding Notes. Neither
the ESOP nor the Company will, directly or indirectly, pay or cause to be paid
any remuneration, whether by way of supplemental or additional interest, fee or
otherwise, to any holder of Notes as consideration for or as an inducement to
the entering into by such holder of Notes of any waiver or amendment of any of
the terms and provisions of this Agreement unless such remuneration is
concurrently paid, on the same terms, ratably to all such holders of Notes.

     14D. FORM, REGISTRATION, TRANSFER AND EXCHANGE OF NOTES; LOST NOTES. The
          --------------------------------------------------------------
Notes are issuable as registered Notes without coupons in denominations of at
least $500,000, except as may be necessary to reflect any principal amount not
evenly divisible by $500,000. The ESOP shall keep or cause to be kept at its
principal office or at the offices of its designated agent (the "ESOP Agent"),
which shall initially be the Trustee or such other ESOP Agent as the ESOP shall
from time to time designate and so notify the holders of the Notes, a register
in which it shall provide for the registration of Notes and of transfers of
Notes. Any registered holder of a Note shall be entitled, upon its written
request, to receive from the ESOP Agent a list of the registered holders of the
Notes and the respective principal amounts of Notes held by such holders. Upon
surrender for registration of transfer of any Note at the

                                      -60-
<PAGE>

principal office of the ESOP Agent it shall, at its expense, execute and deliver
one or more new Notes of like tenor and of a like aggregate principal amount,
which Notes shall be registered in the name of such transferee or transferees.
At the option of the holder of any Note, such Note may be exchanged for Notes of
like tenor and of any authorized denominations, of a like aggregate principal
amount, upon surrender of the Note to be exchanged at the principal office of
the ESOP Agent. Whenever any Notes are so surrendered for exchange, the ESOP
shall, at its expense, execute and deliver the Notes which the holder making the
exchange is entitled to receive. Every Note surrendered for registration of
transfer or exchange shall be duly endorsed, or be accompanied by a written
instrument of transfer duly executed, by the holder of such Note or such
holder's attorney duly authorized in writing. Any Note or Notes issued in
exchange for any Note or upon transfer thereof shall carry the rights to unpaid
interest and interest to accrue which were carried by the Note so exchanged or
transferred, so that neither gain nor loss of interest shall result from any
such transfer or exchange and shall be accompanied by the amortization schedule
required by paragraph 4A. Upon receipt of written notice from the holder of any
Note of the loss, theft, destruction or mutilation of such Note and, in the case
of any such loss, theft or destruction, upon receipt of such holder's unsecured
indemnity agreement, or in the case of any such mutilation upon surrender and
cancellation of such Note, the ESOP will make and deliver a new Note, of like
tenor, in lieu of the lost, stolen, destroyed or mutilated Note, which shall be
accompanied by the amortization schedule required by paragraph 4A.

     14E. PERSONS DEEMED OWNERS; PARTICIPATIONS. Prior to due presentment for
          -------------------------------------
registration of transfer, the ESOP may treat the Person in whose name any Note
is registered as the owner and holder of such Note for the purpose of receiving
payment of principal of and premium, if any, and interest on, such Note and for
all other purposes whatsoever, whether or not such Note shall be overdue, and
the ESOP shall not be affected by notice to the contrary. Subject to the
preceding sentence, the holder of any Note may from time to time grant
participations in all or any part of such Note to any Person on such terms and
conditions as may be determined by such holder in its sole and absolute
discretion, subject to compliance with all applicable securities laws and in
transactions which are consistent with the representations made in paragraph 11.

     14F. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT. All
          ------------------------------------------------------------
representations and warranties contained herein or made in writing by or on
behalf of the parties hereto in connection herewith shall survive the execution
and delivery

                                      -61-

of this Agreement and the Notes, the transfer by you of any Note or portion
thereof or interest therein and the payment of any Note, and may be relied upon
by any Transferee, regardless of any investigation made at any time by or on
behalf of you or any Transferee. Subject to the preceding sentence, this
Agreement and the Notes embody the entire agreement and understanding between
you, the ESOP and the Company and supersede all prior agreements and
understandings relating to the subject matter hereof. The obligations of the
Company and/or the ESOP under paragraph 7, paragraph 8, and paragraph 14B shall
survive the transfer, purchase or payment of any Note (in whole or in part) and
the rights of each Person arising under said paragraphs may not be changed
without the consent of such Person.

     14G. SUCCESSORS AND ASSIGNS. All covenants and other agreements in this
          ----------------------

informal investigative order, (c) in connection with any litigation to which
such holder is a party or (d) in order to protect such holder's investment in
such Note.
