Principal Amount:$1,500,000.00                         Date of Note: June 4,2001

PROMISE TO PAY. OPTIMUMCARE CORPORATION ("BORROWER") PROMISES TO PAY TO U.S.
BANK NATIONAL ASSOCIATION ("LENDER"), OR ORDER, IN LAWFUL MONEY OF THE UNITED
STATES OF AMERICA, THE PRINCIPAL AMOUNT OF ONE MILLION FIVE HUNDRED THOUSAND &
00/100 DOLLARS ($1,500,000.00) OR SO MUCH AS MAY BE OUTSTANDING, TOGETHER WITH
INTEREST ON THE UNPAID OUTSTANDING PRINCIPAL BALANCE OF EACH ADVANCE. INTEREST
SHALL BE CALCULATED FROM THE DATE OF EACH ADVANCE UNTIL REPAYMENT OF EACH
ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING PRINCIPAL
PLUS ALL ACCRUED UNPAID INTEREST ON JUNE 15, 2002. IN ADDITION, BORROWER WILL
PAY REGULAR MONTHLY PAYMENTS OF ACCRUED UNPAID INTEREST BEGINNING AUGUST 15,
2001, AND ALL SUBSEQUENT INTEREST PAYMENTS ARE DUE ON THE SAME DAY OF EACH MONTH
AFTER THAT. The annual interest rate for this Note is computed on a 365/360
basis; that is, by applying the ratio of the annual interest rate over a year of
360 days, multiplied by the outstanding principal balance, multiplied by the
actual number of days the principal balance is outstanding. Borrower will pay
Lender at Lender's address shown above or at such other place as Lender may
designate in writing.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is the prime rate (the "Index").
The unpaid principal balance will bear interest at an annual rate equal to the
percentage point described below plus the prime rate announced by Lender. Lender
will tell Borrower the current Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate change will not occur more often than each time that the prime
rate changes. THE INTEREST RATE TO BE APPLIED TO THE UNPAID PRINCIPAL BALANCE OF
THIS NOTE WILL BE AT A RATE OF 0.500 PERCENTAGE POINTS OVER THE INDEX. NOTICE:
Under no circumstances will the interest rate on this Note be more than the
maximum rate allowed by applicable law.

PREPAYMENT: Borrower agrees that all loan fees and other prepaid finance charges
are earned fully as of the date of the loan and will not be subject to refund
upon early payment (whether voluntary or as a result of default), except as
otherwise required by law.

Except for the foregoing, Borrower may pay without penalty all or a portion of
the amount owed earlier than it is due. Early payments will not, unless agreed
to by Lender in writing, relieve Borrower of Borrower's obligation to continue
to make payments of accrued unpaid interest. Rather, they will reduce the
principal balance due.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform when
due any other term, obligation, covenant, or condition contained in this Note or
any agreement related to this Note, or in any other agreement or loan Borrower
has with Lender. (c) Borrower defaults under any loan, extension of credit,
security agreement, purchase or sales agreement, or any other agreement, in
favor of any other creditor or person that may materially affect any of
Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or statement made or furnished to Lender by Borrower or on
Borrower's behalf is false or misleading in any material respect either now or
at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Borrower is in
default under any other note, security agreement, lease agreement or lease
schedule, loan agreement or other agreement, whether now existing or hereafter
made, between Borrower and U.S. Bancorp or any direct or indirect subsidiary of
U.S. Bancorp. (g) Any creditor tries to take any of Borrower's property on or in
which Lender has a lien or security interest. This includes a garnishment of any
of Borrower's accounts with Lender. (h) Any guarantor dies or any of the other
events described in this default section occurs with respect to any guarantor of
this Note. (i) A material adverse change occurs in Borrower's financial
condition, or Lender believes the prospect of payment or performance of the
Indebtedness is impaired. (j) Lender in good faith deems itself insecure.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon Borrower's failure to pay
all amounts declared due pursuant to this section, including failure to pay upon
final maturity, Lender, at its option, may also, if permitted under applicable
law, increase the variable interest rate on this Note to 5.500 percentage points
over the Index. Lender may hire or pay someone else to help collect this Note if
Borrower does not pay. Borrower also will pay Lender that amount. This includes,
subject to any limits under applicable law, Lender's attorneys' fees and
Lender's legal expenses whether or not there is a lawsuit, including attorneys'
fees and legal expenses for bankruptcy proceedings (including efforts to modify
or vacate any automatic stay or injunction), appeals, and any anticipated
post-judgment collection services. Borrower also will pay any court costs in
addition to all automatic stay or injunction), appeals, and any anticipated
post-judgment collection services. Borrower also will pay any court costs in
addition to all other sums provided by law. THIS NOTE HAS BEEN DELIVERED TO
LENDER AND ACCEPTED BY LENDER IN THE STATE OF CALIFORNIA. IF THERE IS A LAWSUIT,
BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE
COURTS OF SACRAMENTO COUNTY, THE STATE
<PAGE>
OF CALIFORNIA. LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY TRIAL IN
ANY ACTION, PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER
AGAINST THE OTHER. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF CALIFORNIA.

RIGHT OF SETOFF. Borrower grants to lender a contractual security interest in,
and hereby assigns, conveys, delivers, pledges, and transfers to Lender all
Borrower's right, title and interest in and to, Borrower's accounts with Lender
(whether checking, savings, or some other account), including without limitation
all accounts held jointly with someone else and all accounts Borrower may open
in the future, excluding however all IRA and Keogh accounts, and all trust
accounts for which the grant of a security interest would be prohibited by law.
Borrower authorizes Lender, to the extent permitted by applicable law, to charge
or setoff all sums owing on this Note against any and all such accounts.

LINE OF CREDIT. This Note evidences a revolving line of credit. Advances under
this Note may be requested either orally or in writing by Borrower or by an
authorized person. Lender may, but need not, require that all oral requests be
confirmed in writing. All communications, instructions, or directions by
telephone or otherwise to Lender are to be directed to Lender's office shown
above. Borrower agrees to be liable for all sums either: (a) advanced in
accordance with the instructions of an authorized person or (b) credited to any
of Borrower's accounts with Lender. The unpaid principal balance owing on this
Note at any time may be evidenced by endorsements on this Note or by Lender's
internal records, including daily computer print-outs. Lender will have no
obligation to advance funds under this Note if: (a) Borrower or any guarantor is
in default under the terms of this Note or any agreement that Borrower or any
guarantor has with Lender, including any agreement made in connection with the
signing of this Note; (b) Borrower or any guarantor ceases doing business or is
insolvent; (c) any guarantor seeks, claims or otherwise attempts to limit,
modify or revoke such guarantor's guarantee of this Note or any other loan with
Lender; (d) Borrower has applied funds provided pursuant to this Note for
purposes other than those authorized by Lender; or (e) Lender in good faith
deems itself insecure under this Note or any other agreement between Lender and
Borrower.

LATE CHARGE. If a payment is 15 days or more past due, Borrower will be charged
a late charge of 5% of the delinquent payment.

PRIOR NOTE. This Note is given in renewal and extension and not in novation of

indebtedness are hereby renewed and extended to secure the Note and all
renewals, extensions and modifications thereof.

remedies under this Note without losing them. Borrower and any other person who
signs, guarantees or endorses this Note, to the extent allowed by law, waive any
applicable statute of limitations, presentment, demand for payment, protest and

Ladies and Gentlemen:

                  The undersigned, Betz Laboratories, Inc., a Pennsylvania
corporation (the "Company"), Mellon Bank, N.A., in its individual capacity as
indicated and as Trustee of The Betz Laboratories, Inc. Employee Stock Ownership
Trust (the "ESOT") of The Betz Laboratories, Inc. Employee Stock Ownership Plan
(said plan adopted a san employee stock ownership plan under section 407(d)(5)
of ERISA and Section 4975(e) of the Code being herein called the "Plan"), hereby
agree with you as follows:

                  1. AUTHORIZATION OF NOTES. The ESOT will authorize the
issuance, sale and delivery of $100,000,000 aggregate principal amount of its
Guaranteed ESOT Notes (herein, together with any such notes that may be issued
and any such notes that may be issued hereunder in substitution or exchange
therefor, collectively called the "Notes" and individually called a "Note"). The
Notes shall be dated the date of issue thereof, shall bear interest on the
unpaid principal balances thereof from the date thereof until the principal
balance thereof shall become due and payable at the Gross-Up Rate (subject to
the provisions of paragraph 7) and on overdue principal, premium and interest at
the rate specified therein, which Notes, when issued, sold and delivered
pursuant to this Agreement, will be substantially in the form of Exhibit A-1.
Interest on the Notes shall accrue at the rate per annum specified above
(subject to the provisions of paragraph 7), which interest will be payable as
provided in Exhibit A-1 and 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.
<PAGE>
                  2. PURCHASE AND SALE OF NOTES; CLOSING. The ESOT hereby agrees
to sell to you and, subject to the terms and conditions herein set forth, you
agree to purchase notes from the ESOT in the principal amount 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 as you shall request, for an aggregate purchase price of
100% of the principal amount thereof.

                  The issuance, sale and delivery of the Notes to be purchased
by you shall take place at 2:30 P.M. New York time, on June 19, 1989, at the
offices of the Company or on such other date as the Company, the ESOT and you
may agree (the "Closing"). At the Closing, the ESOT 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 Betz Laboratories, Inc. Employee
Stock Ownership Trust c/o Mellon Bank (West), One Mellon Center, Pittsburgh,
Pennsylvania, Account No. 184591. If at the closing the ESOT shall fail to
tender to you the Notes to be purchased by you as provided above in this
paragraph 2, or 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.

                  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:

                  3A. OPINIONS OF COUNSEL. You shall have received from (i)
Drinker Biddle & Reath, counsel for the Company, (ii) Jones Day Reavis & Pogue,
counsel to the ESOT, (iii) William C. Brafford, the Vice President, General
Counsel and Secretary of the Company 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 extend that any opinion referred to above in this
paragraph 3A is rendered in reliance upon 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. REPRESENTATIONS AND WARRANTIES; NO DEFAULT. The
representations and warranties of the ESOT and the Company contained in 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 event referred to in paragraph 4A(b). Each of the ESOT 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 its representations and warranties as to the ESOT in the case of
the ESOT) and further to the effect as to the satisfaction of the conditions
(other than any condition which relates to documents being in form and substance
satisfactory to you) set forth in paragraph 3D (but limited to the conditions
applicable to the ESOT in the case of the ESOT).

                  3C. PURCHASE PERMITTED BY APPLICABLE LAWS. The purchase of and
payment for the Notes to be purchased by you on the date of Closing on the terms
and conditions herein provided (including the use of the proceeds of such Notes
by the ESOT) 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

with this condition.

                  3D. ESOT TRANSACTION. Prior to the Closing you shall have

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; and the purchase of
Employer Capital Stock in the ESOT Transaction shall be duly and validly
consummated concurrently with the Closing hereunder. Except as affected by the

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
(except for the determination letter from the Internal Revenue Service described
in paragraph 5F) and such transactions shall have been consummated substantially
in accordance with the terms of such documents. All material matters relating to
the ESOT, including, without limitation, the amount and the deductibility of
contributions by the Company to the ESOT, the use and sufficiency of such
contributions to pay the Notes shall be satisfactory to you.

                  3E. COMPLIANCE WITH SECURITIES LAWS. The issuance, sale and
delivery of the Notes under this Agreement and the sale of the Employer Capital
Stock in the ESOT Transaction shall have complied in all material respects with
all applicable requirements of Federal and state securities laws and you shall
have received evidence of such compliance in form and substance reasonably
satisfactory to you.

                  3F. APPROVALS AND CONSENTS. The ESOT and the Company shall
each have duly received all authorizations, consents, approvals, licenses,
franchises, permits and certificates by or of, all Federal, state and local
governmental authorities necessary for the issuance, sale and delivery of the
Notes pursuant to this Agreement and the sale and delivery of the Employer
Capital Stock in the ESOT Transaction ("Approvals and Consents"), and all such
Approvals and Consents shall be in full force and effect at the time of Closing
and shall be effective to permit each such issuance, sale and delivery, and you
shall have received such

                                       3

                  3G. PROCEEDINGS. All corporate and other proceedings taken or
to be taken in connection with the transactions contemplated hereby, and all
documents incident thereto shall be satisfactory in form and substance to you
and your special counsel, and you and your special counsel shall have received
all such counterpart originals or certified or other copies of such documents as
you or they may reasonably request.

                  4. PAYMENTS. The Notes shall be subject to payment with
respect to the Required Installment Payments specified in paragraph 4A and shall
be subject to prepayment under the circumstances set forth in paragraph 4B.

                  4A. REQUIRED INSTALLMENT PAYMENTS; REQUIRED REDEMPTION. (a)
The principal amount of the Notes will be due and payable in installment
payments, in each case as set forth on Exhibit A-2. Each such installment
payment is herein called a "Required Installment Payment". Upon any partial
prepayment of Notes pursuant to paragraph 4B, or any partial retirement,
purchase or other acquisition of Notes by the ESOT or the Company, its
Subsidiaries or Affiliates pursuant to paragraph 4D, the ESOT shall elect to
apply such partial prepayment or partial retirement either (i) in inverse order
of the dates on which Required Installment Payments are to be made or (ii)
ratably to the amount of each subsequent Required Installment Payment applicable
to the Notes by an amount equal to the product obtained by multiplying (x) the
aggregate principal amount of the Notes so prepaid, retired, purchased or
acquired by (y) a fraction the numerator of which is the amount of such Required
Installment Payment with respect to the Notes and the denominator of which is
the unpaid principal balance of the Notes immediately prior to such prepayment,
retirement, purchase or acquisition, as the case may be.

                  (b) The principal amount of the Notes, the interest accrued
thereon and the Market Premium will be due and payable in the event that the
ESOT (i) is terminated, (ii) fails to continue to hold sufficient Qualifying
Employer Securities required pursuant to Section 4975(e)(7) of the Code or (iii)
fails to obtain and deliver to you the determination letter required pursuant to
paragraph 5F prior to the Qualification Date. Notwithstanding the foregoing,
upon the occurrence of any of the events described in this paragraph 4A(b), no
amount shall be due and payable in the event the Company elects, in the manner
described herein, to issue, sell and deliver to each holder of the Notes senior
promissory notes of the Company substantially in the form of Exhibit A-3 (the
"Company Note") with a maturity date, in principal amounts and with repayment
schedules identical to the Notes redeemed, that were held by such holder, at a
purchase price equal to the principal amount hereof. The Company Notes shall be
dated the date of issuance and shall bear interest at the Gross-Up Rate from the
last date as of which interest had been paid on the Notes and the holders
thereof shall be entitled to the benefits of this Agreement. Upon and after
issuance of the Company Notes, references to "Notes" herein shall be deemed to
also include the Company Notes. The Company Notes shall be legal, valid and
binding obligations of the Company, enforceable in accordance with their terms,
subject to applicable bankruptcy, insolvency, reorganization, moratorium and
similar laws affecting creditors rights generally, and upon issuance thereof the
Company, at its expense, shall deliver an opinion of counsel addressed to the
purchasers of the Company Notes and satisfactory to such

                                       4
<PAGE>
purchasers to the foregoing effects and covering such other matters as may be
reasonably requested by such purchasers.

                  4B. OPTIONAL PREPAYMENT. The Notes shall be subject to
prepayment, at any time in whole, or from time to time on the date of any
Required Installment Payment in part (in a minimum aggregate principal amount of
$1,000,000, provided, however, that the Company may make prepayments in amounts
less than $1,000,000 if such prepayments are required in order to comply with
ERISA), at the option of the ESOT, at 100% of the principal amount thereof to be
prepaid, together with accrued interest thereon to the prepayment date and the
Market Premium, with respect to each Note. Upon any partial prepayment of the
Notes pursuant to this paragraph 4B, the principal amount so prepaid shall be
allocated to all Notes at the time outstanding in proportion to the respective
outstanding principal amounts thereof.

                  4C. NOTICE OF PREPAYMENTS. The ESOT shall give each holder of
Notes irrevocable written notice of any prepayment of the Notes pursuant to
paragraph 4B not less than 10 days prior to the prepayment date, specifying such
prepayment date and the principal amounts of the notes held by such holder to be
prepaid on such date and stating that such prepayment is being made pursuant to
paragraph 4B and specifying whether the amount to be prepaid shall be applied
against future Required Installment Payments in accordance with clause (i) or
(ii) of paragraph 4A(a), whereupon the principal amount of the Notes to be
prepaid, together with interest accrued thereon to the prepayment date and the
Market Premium, with respect to each Note, shall become due and payable on such
prepayment date.

                  4D. ACQUISITION OR RETIREMENT OF NOTES. The Company, its
Subsidiaries, Affiliates and the ESOT shall be permitted to retire in whole or
in part prior to their stated maturity, or purchase or otherwise acquire,
directly or indirectly, notes held by any holder. Any Notes retired, purchased
or otherwise acquired by the Company or any of its Subsidiaries or Affiliates or
the ESOT shall not be deemed to be outstanding for any purpose under this
Agreement and the Company shall specify whether the principal amount of the
Notes retired, purchased or otherwise acquired by the Company shall be applied
against future Required Installment Payments in accordance with clause (i) or
(ii) of paragraph 4A(a).

                  4E. OBLIGATIONS OF THE TRUSTEE; NO RECOURSE. Except with
respect to paragraph 10O(b), the covenants, agreements and all obligations of
the Trustee hereunder are solely obligations of the Trustee in its capacity as
Trustee under the ESOT, to be satisfied solely out of the assets of the ESOT,
and no liability shall attach to, or be incurred by, the Trustee in its
corporate capacity under or by reason of any of the obligations, covenants or
agreements contained herein. Notwithstanding any other provision hereof, none of
the holders of the Notes shall have any recourse against the Trustee of the
ESOT, except to the extent of the assets of the ESOT that are permitted by
Treasury Regulation Section 54.4975-7(b)(5) and 54.4975-7(b)(6) to be used to
repay the Notes.

                  5. AFFIRMATIVE COVENANTS. The provisions of this paragraph 5
shall remain in effect from the date hereof and thereafter so long as any Note
shall remain outstanding.

                  5A. FINANCIAL STATEMENTS AND OTHER REPORTS. The Company
covenants that it will deliver to each holder of a Note in duplicate:

                                       5
<PAGE>

                  (i) as soon as is practicable and in any event within 45 days
         after the end of each quarterly period (other than the last quarterly
         period) in each fiscal year commencing with the first such quarter
         ending after the date of the Closing, a consolidated statement of
         income of the Company and its Subsidiaries for such quarterly period,
         and a consolidated balance sheet of the Company and its Subsidiaries as
         at the end of such quarterly period, setting forth in each case in
         comparative form, figures for the corresponding period in the preceding
         fiscal year, all in reasonable detail and certified as complete and
         correct and prepared in accordance with generally accepted accounting
         principles by an authorized financial officer of the Company, subject
         to changes resulting from year-end adjustments; provided, however, that
         delivery of substantially the same financial statement information that
         is required by a Quarterly Report on Form 10-Q or any successor form of
         the Company for such quarterly period as such form is in effect on the
         date hereof under the Exchange Act shall be deemed to satisfy the
         requirements of this clause (i);

                  (ii) as soon as practicable and in any event within 90 days
         after the end of each fiscal year, a consolidated statement of income
         and of cash flow of the Company and its Subsidiaries for such year, and
         a consolidated balance sheet of the Company and its Subsidiaries as at
         the end of such year, setting forth in each case in comparative form,
         corresponding consolidated figures from the preceding annual audit, all
         in reasonable detail and reasonably satisfactory in scope to the
         Required Holder(s), and accompanied by an opinion directed to the
         Company of independent public accountants of recognized national
         standing selected by the Company to the Required Holder(s); provided,
         however, that delivery of substantially the same financial statement
         information that is required by an Annual Report on Form 10-K of any
         successor form (including all incorporated documents) of the Company
         for such fiscal year as such form is in effect on the date hereof under
         the Exchange Act shall be deemed to satisfy the requirements of this
         clause (ii);

                  (iii) promptly upon transmission thereof, copies of all such
         financial statements, proxy statements, notices and reports as it shall
         send to its public stockholders and copies of all registration
         statements (without exhibits), other than on Form S-8 or any similar
         successor form (except to the extent such registration statement on
         Form S-8 relates to the Plan), and all public reports which it files
         with the Commission;

                  (iv) in the event the Company Notes are not outstanding,
         promptly upon its becoming available and in any event within 30 days
         after such time as such reports are required to be filed with the IRS,
         a copy of the annual report of the Plan on Form 5500;

                  (v) in the event the Company Notes are not outstanding,
         promptly upon their becoming available, copies of the Annual Report on
         Form 11-K of the Plan as filed with the Commission;

                  (vi) in the event the Company Notes are not outstanding,
         promptly following the Company's obtaining knowledge thereof, a notice
         of the occurrence of any event that could, in the reasonable judgment
         of the Company, be expected to give rise to

                                       6
<PAGE>

         a change in the interest rate applicable to the Notes or the payment of
         any amount by the ESOT pursuant to paragraph 7; provided, however, that
         the Company shall not be required pursuant to this clause (vi) to give
         notice of the introduction or enactment of any amendments to ERISA or
         the Code or of the proposal or adoption of any regulations under either
         ERISA or the Code or any other matter of public knowledge; and

                  (vii) with reasonable promptness, such other financial data as
         any holder(s) may reasonably request.

Together with each delivery of financial statements required by clauses (i) and
(ii) above, the Company will deliver to each holder of Notes an Officer's
Certificate demonstrating (with computations in reasonable detail) compliance by
the Company and its Subsidiaries with the provisions of paragraphs 6A, 6B and 6C
and stating that there exists no Event of Default, Default or event referred to
in paragraph 4A(b), or, if any such Default or event exist, specifying the
nature and period of existence thereof and what action the Company proposes to
take with respect thereto. Together with each delivery of financial statements
required by clause (ii) above, the Company will deliver to each holder of Notes
a certificate of such accountants stating that, in making the audit necessary to
the certification of such financial statements, they have obtained no knowledge
of any Event of Default, Default or event referred to in paragraph 4A(b), or, if
they have obtained knowledge of any such Default or event, specifying the nature
and period of existence thereof. Such accountants, however, shall not be liable
to anyone by reason of their failure to obtain knowledge of any Event of
Default, Default or event referred to in paragraph 4A(b), which would not be
disclosed in the course of an audit conducted in accordance with generally
accepted auditing standards. The Company also covenants that forthwith upon the
chief executive officer, chief operating officer, principal financial officer,
principal accounting officer or treasurer of the Company obtaining actual
knowledge of an Event of Default, Default or event referred to in paragraph
4A(b), it will deliver to each holder of Notes an Officer's Certificate
specifying the nature and period of existence thereof and what action the
Company proposes to take with respect thereto.

                  5B. INSPECTION OF PROPERTY. The Company will permit any
authorized representative designated by you or any other holder, without expense
to the Company, to visit and inspect any of the properties of the Company or any
of its Subsidiaries, including its and their financial and accounting records,
and to make copies and take extracts therefrom, and to discuss its and their
affairs, finances and accounts with its and their officers and, in or outside of
the presence of any officers or employees of the Company and its Subsidiaries,
with its and their independent public accountants (any expenses and fees of
which shall be paid by the Company), all upon reasonable notice and at such
reasonable times during normal business hours and as often as may be reasonably
requested insofar as relevant to your investment in the Notes. You agree (and
any holder seeking to avail itself of the benefits of this paragraph 5B shall
similarly agree) to use your best efforts to maintain the confidentiality of
non-public information regarding the Company and its Subsidiaries which you or
such holder, as the case may be, receive pursuant to this paragraph 5B in
accordance with such procedures as you or such holder, as the case may be, apply
generally to information of this kind. You agree not to use such non-public
information for purposes other than purposes related to this Agreement except
where you deem (and any holder seeking to avail itself of the benefits of this
paragraph 5B similarly deems) such use to be necessary in order to comply with
any law, rule, regulation or order applicable to you (or such other holder)
including, but not limited to, the filing of any

                                       7
<PAGE>
reports with federal, state or self-regulatory agencies having jurisdiction over
you (or such other holder).

                  5C. PAYMENT OF TAXES AND CLAIMS. The Company will pay or
discharge, or cause to be paid or discharged, before the same shall become
delinquent (i) all taxes, assessments and governmental charges (including claims
of the IRS and the PBGC and claims made at the insistence of the PBGC) levied or
imposed upon it or its Subsidiaries or upon its or their income, profits or
property, except where non-payment would not (either singly or in the aggregate)
have a material adverse effect on the Company and its Subsidiaries taken as a
whole or the ability of the Company to perform and satisfy its obligations under
this Agreement, (ii) all lawful claims for labor, materials and supplies, which,
if unpaid, might by law become a lien upon its or its Subsidiaries properties,
except where non-payment would not (either singly or in the aggregate) have a
material adverse effect on the Company and its Subsidiaries taken as a whole or
the ability of the Company to perform and satisfy its obligations under this
Agreement and (iii) all required installments under section 412(m) of the Code
and all other required payments under section 412 of the Code with respect to
any pension plan maintained by the Company or a Code Affiliate; provided,
however, that the Company shall not be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

                  5D. CORPORATE EXISTENCE. Subject to paragraph 6E, the Company
will do or cause to be done all things necessary to preserve and keep in full
force and effect its corporate existence, rights, (charter and statutory) and
franchises; provided, however, that the Company shall not be required to
preserve any such right or franchise if the Board of Directors shall determine
that the preservation thereof is no longer desirable in the conduct of the
business of the Company and that the loss thereof is not disadvantageous in any
material respect to the holders of the Notes.

                  5E. MAINTENANCE OF PROPERTIES. The company will cause all
properties of material value used or useful in the conduct of its business or
the business of any Subsidiary to be maintained and kept in good condition,
repair and working order and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as in the judgment of the Company may be necessary so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
paragraph 5E shall prevent the Company from discontinuing the operation or
maintenance of any of such properties if such discontinuance is, in the judgment
of the Company, desirable in the conduct of its business or the business of any
Subsidiary and not disadvantageous in any material respect to the holders of the
Notes.

                  5F. DETERMINATION LETTER. The Company will promptly apply for
(but in no event later than September 30, 1989), and use its best efforts to
obtain and deliver to you as promptly as practicable, a determination letter
from the IRS to the effect that the Plan meets the requirements for
qualification under sections 401(a) and 4975(e)(7) of the Code and the ESOT
meets the requirements for tax exemption under section 501(a) of the Code and
comply with any reasonable request from any Indemnitee for assistance in
establishing the status

                                       8
<PAGE>
of the Plan as an "employee stock ownership plan" under Section 4975(e)(7) of
the Code or the status of any Note as a "securities acquisition loan" under
section 133 of the Code.

                  5G. PLAN EXISTENCE. As long as the Company Notes are not
outstanding, each of the Company and the ESOT will (i) do all things necessary
to comply with the requirements for an "exempt loan" to the ESOT as defined in
Treasury Regulation sections 54.4975-7 and 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 maintain and keep in full force and
effect the Plan as an "employee stock ownership plan", within the meaning of
section 4975(e)(7) of the Code and section 407(d)(6) of ERISA; (iii) cause the
Plan and the ESOT to be operated and administered at all times and be amended as
necessary so as to remain qualified under sections 401(a) and 4975(e)(7) of the
Code and the ESOT to remain tax-exempt under section 501(a) of the Code; (iv)
cause all other actions to be taken which are necessary for the Plan and the
ESOT to be in material compliance with all applicable requirements of ERISA
(including Titles I and II thereof) and the Code and the regulations thereunder
as from time to time in effect and applicable to the Plan and the ESOT; (v) take
no action to amend or otherwise modify any Plan Document in a manner that would
result in the extension of credit represented by the Notes (if so qualified)
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 ESOT as required by the Plan. Nothing in this paragraph 5G
is intended to give any Person, other than the holders from time to time of the
Notes, any rights.

                  5H. APPLICATION OF PROCEEDS. The entire proceeds of the
issuance and sale of the Notes will be used promptly by the ESOT to acquire, at
not more than adequate consideration (within the meaning of Section 3(18) of
ERISA), shares of the Employer Capital Stock in accordance with the Stock
Purchase Agreement. The ESOT and the Company will furnish to you, if required in
connection with your purchase of the Notes hereunder, a statement in conformity
with applicable margin requirements of the Federal Reserve under Regulation G
our U.

                  5I. ADDITIONAL COVENANTS PENDING CLOSING. Pending the Closing,
the Company will promptly advise you of any action or event of which it becomes
aware which has the effect of making any of the representations and warranties
contained herein incorrect in any material respect or which has the effect of
rendering the Company incapable of performing any of the covenants contained
herein which it is required to perform.

                  5J. COMPLIANCE WITH ENVIRONMENTAL LAWS. The Company will, and
will cause each of its Subsidiaries and each of its Affiliates that are
controlled by the Company or its Subsidiaries to, comply in a timely fashion
with, or operate pursuant to valid waivers of the provision of, all federal,
state and local environmental or pollution-control laws, regulations, orders and
decrees governing, without limitation, the emission of wastewater effluent,
solid and hazardous waste and air pollution, and laying down general
environmental conditions, together with any other applicable requirements for
conducting, on a timely basis, periodic tests and monitoring for contamination
of ground water, surface water, air and land and for biological toxicity of the
aforesaid, and diligently comply with the regulations (except to the extent such
regulations are waived) of any relevant Department of Environmental Protection
except where noncompliance would not adversely affect the business, condition
(financial or

                                       9
<PAGE>
other) or operations of the Company, its Affiliates or its Subsidiaries. The
Company and its Subsidiaries agree, jointly and severally, to indemnify and hold
you, your officers, agents and employees harmless from any loss, liability,
claim or expense which you may incur or suffer as a result of a breach by the
Company or its Subsidiaries, as the case may be, of this covenant.

                  5K. CONTRIBUTIONS TO THE ESOT. As long as the Company Notes
are not outstanding, the Company covenants that it will make contributions to
the ESOT in amounts sufficient, together with other funds legally available
therefor, to enable the Trustee to make payments of principal, Market Premium,
if any, and interest on the Notes when due. Nothing in this paragraph 5L is
intended to give any Person, other than the holders of the Notes, any rights.

                  6. NEGATIVE COVENANTS. The provisions of this paragraph 6
shall remain in effect only so long as any Note shall remain outstanding. If the
Company and the Required Holders agree on mutually satisfactory arrangements for
the defeasance of the Notes pursuant to which (i) the holders of the Notes have
the benefit of a security interest in United States Treasury securities and (ii)
the payment when due of all principal and interest on the Notes is provided for,
the Required Holders shall waive the provisions of paragraphs 6A, 6B, 6C and 6D,
and shall amend the percentage set forth in paragraph 6F from 30% to 50%, for so
long as such arrangements remain in effect.

                  6A. TANGIBLE NET WORTH. The Company will not permit
Consolidated Tangible Net Worth at any time to be less than $120,000,000 plus
the Cumulative Net Income Amount.

                  6B. DEBT SERVICE COVERAGE. The Company covenants that it will
not permit the ratio of (i) the sum of Consolidated Net Income, Interest
Expense, Rent Expense and Tax Expense for any fiscal year to (ii) Fixed Charges
for such fiscal year, to be less than 3.5 to 1.

                  6C. LIMITATION ON FUNDED DEBT. The Company covenants that it
will not, and will not permit any of its Subsidiaries to, create, incur, assume
or otherwise become liable with respect to or suffer to exist at any time any
Funded Debt if immediately after the incurrence thereof, Consolidated Funded
Debt less cash and Cash Equivalents would at any time exceed 50% of the
Consolidated Tangible Gross Worth less cash and Cash Equivalents.

                  6D. LIMITATION ON LIENS. (a) The Company will not, nor will it
permit any Subsidiary to, create, issue, assume, incur or suffer to exist at any
time any Mortgage upon any of its property or assets, (whether now owned or
hereafter acquired), or upon any income or profits therefrom, or acquire any
property pursuant to any conditional sale, lease purchase or other title
retention agreement, without in any such case effectively providing,
concurrently with such creation, issuance or assumption, that the Company's
obligations under paragraph 8 (the "Company Obligations") shall be secured
equally and ratably by such Mortgage; provided, however, that, subject to clause
(b), the foregoing restrictions shall not apply to

                  (1) Mortgages existing on the date hereof;

                  (2) Mortgages on property existing at the time of acquisition
         on such property by the Company or a Subsidiary, or Mortgages to secure
         the payment of all or any part of the purchase price of such property
         upon the acquisition of such property by the

                                       10
<PAGE>
         Company or a Subsidiary or to secure any Debt incurred or guaranteed by
         the Company or a Subsidiary prior to, at the time of, or within 120
         days after the later of the acquisition, completion of construction
         (including any improvements on an existing property) or commencement of
         full operation of such property, which Debt is incurred or guaranteed
         for the purpose of financing all or any part of the purchase price
         thereof or construction or improvements thereon; provided, however,
         that (a) the aggregate principal amount of indebtedness secured by such
         Mortgages in respect of any such property shall not exceed the fair
         market value of such property at the time of acquisition or completion
         of construction thereof; and (b) the sum of consolidated Debt secured
         by such Mortgages was incurred within the limitations of paragraph 6C;

                  (3) Mortgages securing Debt of a Subsidiary owing to the
         Company or to another Subsidiary;

                  (4) Mortgages on property of a corporation existing at the
         time such corporation is merged into or consolidated with the Company
         or a Subsidiary or at the time of an acquisition of a corporation or a
         purchase, lease or other acquisition of the property of a corporation
         or firm as an entirety or substantially as an entirety by the Company
         or a Subsidiary provided, however, that (a) such Mortgages exist at the
         time of acquisition or such corporation or assets and is not created by
         the Company in anticipation thereof and (b) the consolidated Debt
         secured by such Mortgage was incurred within the limitations of
         paragraph 6C;

                  (5) other Mortgages incidental to the conduct of the Company
         or its Subsidiaries business or the ownership of the Company or its
         Subsidiaries property and assets, which were not incurred in connection
         with the borrowing of money or the obtaining of advances or credit, and
         which do not in the aggregate materially detract from the value of the
         Company or its Subsidiaries' property or assets, or materially impair
         the use thereof in the operation of the Company or its Subsidiaries
         business;

                  (6) any extension, renewal or replacement (or successive
         extensions, renewals or replacements) in whole or in part of any
         Mortgage referred to in the foregoing clauses (1) to (5), inclusive;
         provided, however, that the principal amount of Debt secured thereby
         shall not exceed the principal amount of Debt so secured at the time of
         such extension, renewal or replacement, and that such extension,
         renewal or replacement shall be limited to all or part of the property
         which secured the Mortgage so extended, renewed or replaced (plus
         improvements and construction on such property).

                  (b) Notwithstanding the foregoing provisions of this paragraph
6D, the Company and any one or more Subsidiaries may not issue, assume or
guarantee Debt secured by Mortgages which would otherwise be permitted by any of
the foregoing clauses (1) through (4) or (6) if the aggregate amount thereof
would exceed 10% of Consolidated Tangible Gross Worth as of the end of the
fiscal year preceding the date of determination.

                  6E. CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE. (a)
Neither the Company nor any of its Subsidiaries shall consolidate with or merge
into any other corporation or convey, transfer or lease its properties and
assets substantially as an

                                       11
<PAGE>

entirety to any Person (except that a Subsidiary may merge with and into a
wholly-owned Subsidiary), unless:

                  (1) in the case of the Company, 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 Holder(s) (with respect to the covenants in paragraph 8, a
         guaranty in the form described in paragraph 8 will be deemed to be
         satisfactory to the Required Holder(s)), the due and punctual
         performance of the Company Obligations and the payment and performance
         of 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 consolidation or merger, the Company or
         the corporation formed by such consolidation or into which the Company
         is merged could incur at least $1 of additional Funded Debt under the
         terms of this Agreement.

                  (3) 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, and no event which, after notice or lapse of time or
         both, would become an Event of Default, shall have happened and be
         continuing; and

                  (4) 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 6E and that all
         conditions precedent herein provided for relating to such transaction
         have been complied with.

                  (b) Upon any consolidation by the Company with or merger by
the Company into any other corporation or any conveyance, transfer or lease of
the properties and assets of the Company substantially as an entirety in
accordance with paragraph 6E(a), the successor corporation formed by such
consolidation or into which the Company is merged or to which such conveyance,
transfer 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 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
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 Subsidiary or their successors shall be a party or parties, or
upon any sale, conveyance or lease of the property of the

                                       12
<PAGE>

Company as an entirety or substantially as an entirety to any other Person
(whether or not an Affiliate of the Company), any property of the Company or of
any Subsidiary owned immediately prior thereto would thereupon become subject to
any Mortgage, the Company or any such 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 by a direct lien on all
such properties of the Company or any such Subsidiary, prior to all liens other
than any theretofore existing thereon, unless such Mortgage would be permitted
by paragraph 6D, treating, for the purposes of paragraph 6A, the indebtedness of
the other Person secured by such Mortgage as Debt.

                  6F. SALE OF ASSETS. Neither the Company nor any Subsidiary
shall sell, lease, transfer or otherwise dispose of any asset to any Person
(other than assets disposed of in the ordinary course of business) unless such
asset, together with all other assets (other than assets disposed of in the
ordinary course of business) sold, leased, transferred or otherwise disposed of
during the preceding 12-month period, (i) does not have a net book value greater
than 30% of Consolidated Tangible Net Worth of the Company and its Subsidiaries
at the end of the immediately preceding fiscal year of (ii) did not, for any of
the three immediately preceding fiscal years, contribute more than 30% of
Consolidated Operating Profit.

                  7. INCOME TAXATION.

                  7A. ADDITIONAL PAYMENTS. In the event that at any time on or
after January 1, 1991 (whether before or after payment on the Notes) a Gross-Up
Event shall occur with respect to any Indemnitee, the ESOT 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 (appropriately reduced if the amount
         of interest on such Indemnitee's Note included in its Federal Gross
         Income shall exceed the Inclusion Rate but shall be less than 100% as
         determined in accordance with the provisions of paragraph 7D); over

                      (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

                                       13
<PAGE>
         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
         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 at any time
after the date hereof (whether before or after payment of the Notes) a Change of
Law shall occur with respect to any Indemnitee, the ESOT will pay to such
Indemnitee as additional interest in immediately available funds at the time or
times specified in paragraph 7C an amount with respect to the applicable
Supplemental Payment Period 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, shall be
equal to any new or additional Federal tax related to the acquisition, ownership
or disposition of such Indemnitee's Note which arises (and for this purpose tax
arises, among other events, as a result of a reduction in any Tax Allowance) as
a result of such Change of Law (all such taxes to be calculated at the maximum
statutory rate applicable to such Indemnitee) and adjusted to reflect any
increased deductions or credits available to the Indemnitee related to the
acquisition, ownership or disposition of such Indemnitee's Note which arises as
a result of such Change of Law.

                  (b) In the case of any Change of Law with respect to the
alternative minimum tax, the additional tax which is attributable to the ESOT
and which arises as a result of such Change of Law will equal the excess, if any
of (i) the amount by which the Indemnitee's alternative minimum tax liability
after the Change of Law would decrease if no portion of the interest on the Note
otherwise included as a "preference item" or other adjustment in computing
"alternative minimum taxable income" is so included over (ii) the amount
computed in (i) but determined as if the Change of Law had not occurred. For
this purpose, the law to be applied in (ii) above shall be the law as of the
date hereof (including changes already enacted and scheduled to go into effect).
Once such excess is determined, the provisions of paragraph 7B(a) which
determine the proper amount of additional interest owed to the Indemnitee (as a
result of the provisions of such paragraph) shall be applied and payment shall
be made in accordance with the schedule provided in paragraph 7C.

                  (c) Notwithstanding anything to the contrary in this paragraph
7B, the amount of Supplemental Payment for any Supplemental Payment Period shall
not, when added to the

                                       14
<PAGE>
interest otherwise payable for such period, exceed the Gross-Up Rate for such
period and paragraph 7B shall be applicable only after January 1, 1991 for any
Change of Law (including for this purpose any Change of Law prior to January 1,
1991 but after the date hereof).

                  7C. PAYMENT DATES. (a) If the ESOT becomes obligated to make
payments to any Indemnitee pursuant to paragraph 7A, the Indemnitee shall from
time to time notify the ESOT 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, the ESOT and the Company may elect not to make any
payments due hereunder 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 of such increased Federal tax
(including any interest and Additions to Tax) shall be paid by the ESOT to the
Indemnitee promptly upon its receipt of notice of such payment from the
Indemnitee.

                  (b) If the ESOT becomes obligated to make payments to any
Indemnitee pursuant to paragraph 7B, such Indemnitee shall notify the ESOT and
the Company (i) of the amount that is payable in respect of such portion of the
Supplemental Payment Period as had elapsed prior to the date such notice is
given, which amount shall be due and payable within 10 days after the date of
such notice, and (ii) at least annually, of the amount that will be payable on
such date or dates thereafter as set forth in such notice (each of which shall
be at least 10 days after the date of such notice), which amount shall become
due and payable on the dates specified.

                  (c) 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 ESOT and the Company, but neither the ESOT 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 ESOT'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 ESOT, as the case may be, that such computation is
accurate in all material respects.

                  (d) If the ESOT shall fail to pay any amount payable under
paragraphs 7A or 7B on the due date pursuant to this paragraph 7C, the ESOT
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.

                                       15
<PAGE>
                  7D. INTEREST RATE ADJUSTMENT. In the event that at any time on
or after January 1, 1991 there is for any reason a change in the Federal Tax
Rate or the Inclusion Rate, then, in that event, the interest rate on the Notes
held by each Qualified Holder 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 Qualified Tax-Exempt Rate by
the Adjustment Fraction. Each Qualified Holder shall determine the adjusted
interest rate on its Notes in accordance with the foregoing, subject to the
procedures described in paragraph 7C(c). The ESOT unconditionally promises to
pay interest on such Notes from the date of each 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, adjustments
to payments are required under this paragraph 7D, (i) the ESOT shall promptly
upon demand by such Qualified Holder pay the amount by which interest computed
at such rate or rates exceeds the amount of interest actually theretofore paid
by the ESOT on the Notes or (ii) such Qualified Holder shall promptly upon
demand for refund by the ESOT pay the amount by which the interest computed at
such rate or rates is exceeded by the amount of interest theretofore paid by the
ESOT on the Notes.

                  7E. REFUNDS. (a) If the ESOT 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 (or if it is otherwise subsequently determined that
payments pursuant to paragraph 7A or 7B exceeded the amounts properly payable to
the Indemnitee with respect to a Gross-Up Event or Change of Law, in which
event, for purposes of this paragraph 7E(a), the Indemnitee shall be treated as
receiving a refund in the amount of such excess) such Indemnitee shall pay to
the ESOT 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 the
         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 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 tax paid by such Indemnitee
         with respect to such Disputed Interest; and

                      (ii) the amount of any refunded, offset of 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 pursuant to paragraph 7A(b) or 7B.

                      (iii) to the foregoing amounts shall be added interest
         from the date that the amount was paid to the Indemnitee to the date of
         repayment pursuant to this paragraph, at the rate at which interest for
         such period would be paid on refunds by the IRS.

For purposes of this paragraph 7E(a), 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

                                       16
<PAGE>
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 portion of the
amount paid pursuant to paragraph 7A that was determined with reference to the
interest excluded on the return. If the ESOT or the Company so requests in
writing at any time the Indemnitee shall confirm in writing whether or not it
has so excluded such interest.

                  (b) If the ESOT 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 from the amount used to compute the amount of
such payment, the ESOT 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 ESOT or the
Company, as the case may be, any excess amount paid pursuant to paragraph 7B,
attributable to such difference.

                  7F. CONTEST OF DISALLOWANCE OF SECTION 133 EXCLUSION.

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

                  (b) 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 each instance) so requested by the ESOT or the
Company; provided, however, that:

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

                      (ii) prior to the Indemnitee's taking any such requested
         action (including appealing any adverse decision), the ESOT or the
         Company (at the expense of either the ESOT 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 ESOT and the Company and
         reasonably satisfactory to the Indemnitee to the effect that there
         exists a reasonable basis for contesting such Exclusion Claim:

                      (iii) The ESOT or the Company shall from time to time pay
         to the Indemnitee within 30 days after receipt by the ESOT and the
         Company of an itemized written demand therefor and explanation thereof
         an amount sufficient, on an after-tax basis, 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

                                       17
<PAGE>
                      (iv) the Indemnitee may, at any time, settle, compromise
         or otherwise terminate any contest with the consent of the ESOT and the
         Company, which consent shall not be unreasonably withheld.

                  (c) 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 ESOT, 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 ESOT, the Company, and their
counsel as to conduct of the contest. The right of the Indemnitee to control the
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).

                  (d) Notwithstanding anything to the contrary contained in
subparagraph (a), (b) or (c) of this paragraph 7F, the Indemnitee may in its
sole discretion settle of compromise any Exclusion Claim, provided the
Indemnitee gives the ESOT and the Company notice of its intention to settle or
compromise the 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 ESOT 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 issue, then, to the
extent payment was made by the ESOT or the Company under paragraph 7A, the
Indemnitee shall be deemed to have received a refund in the amount to the ESOT
or the Company; to the extent payment was not made, the Gross-Up Event giving
rise to the disallowance 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 ESOT 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 issue, then if the amount paid by the ESOT or the Company exceeds 50% of
the amount payable pursuant to paragraph 7A, the Indemnitee shall pay such
excess to the ESOT or the Company, as appropriate; and if 50% of the amount
payable pursuant to paragraph 7A exceeds the amount paid by the ESOT or the
Company, the ESOT 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 substantial 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 a Qualifying Opinion of Counsel with respect to interest on the Notes
for a period commending 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 as may be reasonably
requested by such counsel in order for it to form a basis for rendering the
opinion requested.

                                       18
<PAGE>

                  7H. ADJUSTMENT EVENT. If on January 1, 1991 the Inclusion Rate
is 50% and the Federal Tax Rate then in effect is equal to the Federal Tax Rate
on the date hereof, the interest rate on the Notes held by each Qualified Holder
shall be automatically adjusted, effective on January 1, 1991, to the Qualified
Tax-Exempt Rate until further adjusted pursuant to paragraph 7. If on January 1,
1991 the Inclusion Rate is not 50% or if the Federal Tax Rate in effect on that
date is different than the Federal Tax Rate in effect on the date hereof, the
interest rate on the Notes shall be adjusted first to the Qualified Tax-Exempt
Rate and then shall be immediately further adjusted pursuant to the principles
of paragraph 7D; such adjusted interest rate shall also be subject to further
adjustments pursuant to this paragraph 7.

                  7I. ISSUANCE OF COMPANY NOTES. The Company and its
Subsidiaries hereby assume liability for, shall pay and discharge from time to
time, will indemnify and hold harmless the holder of any Note from, and the
Company and its Subsidiaries will pay immediately to such holder any amount due,
on a gross-up basis, with respect to any present or future taxes or tax
liability imposed, collected, assessed or required to be deducted, withheld or
paid by such holder with respect to the issuance of the Company Notes pursuant
to paragraph 4A(b).

                  8. GUARANTEE BY THE COMPANY.

                  (a) 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, without
limitation, the Market Premium, if any) and interest on the Notes 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 ESOT hereunder (including,
without limitation, amounts payable by the ESOT pursuant to paragraph 7),
whether absolute or contingent, liquidated or unliquidated. In the absence of
the due observance and performance by the ESOT 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 achieve comparable results. If the ESOT shall not
punctually pay any such principal, premium (including, without limitation, the
Market Premium, if any), interest or other amounts (regardless of whether the
holders of the Notes have recourse against the ESOT), 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 the provisions of Treasury Regulation section 54.4975-7
and 54.4975-11, the Company, upon demand therefore, 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) The Company agrees that its obligations hereunder are
absolute and unconditional, irrespective of the validity, regularity or
enforceability of or any change in or

                                       19
<PAGE>
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
judgment against the ESOT or any action to enforce the same, the inability to
recover from the ESOT because of any structure of limitations, laches or
otherwise or any other circumstance which might otherwise constitute a legal or
equitable discharge of or a defense to guarantor, and that the provisions of
this paragraph 8 constitute a guarantee of payment and not of collectibility.

                  (c) 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 ESOT (subject to such filings as may
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
Company, any marshalling of assets of the Company or the ESOT, any notice of
default with respect to any of the Notes or this Agreement or 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 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 of 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 ESOT 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 of the
Company to enforce any rights it may have against any Person by way of a
separate proceeding or action.

                  (d) 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) or exercise or refrain from
exercising any rights against the ESOT or others; and (ii) to apply any sums, by
whomsoever paid or however realized, to the payment of the principal of,
premium, if any, 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 ESOT or any other Person or to pursue any other
remedy available to the Purchaser or to such holders.

                  (e) In the event the ESOT fails to observe or perform any of
its obligations or undertakings under this Agreement (an "ESOT 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 ESOT by the Purchaser or
such holders as a result of any such ESOT 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 ESOT pursuant to the Notes and this Agreement at the time of the Company's
exercise of any such right shall have been performed, observed or

                                       20
<PAGE>

paid in full by the ESOT or the Company. In the event that the Company receives
any payment on account of such subrogation rights, it shall promptly apply 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 ESOT which it is forbidden to exercise pursuant to
ERISA or the Code or the regulations thereunder including but not limited to
Treasury Regulation sections 54.4975-7 and 54.4975-11.

        (f) 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,
Market 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 subsequent holder of Notes upon the insolvency,
bankruptcy or reorganization of the ESOT, or otherwise, all as though such
payment has not been made.

        (g) The Company may at any time elect to pay or otherwise perform any
obligation of the ESOT under this Agreement or in respect of the Notes, which
shall operate as a discharge and release of the ESOT 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 ESOT from any of its other obligations hereunder and under the
Notes.

         (other than proceedings for the voluntary liquidation and dissolution
         of a Subsidiary) relating to the Company or any Subsidiary under the
         Bankruptcy Law of any other jurisdiction; or

                  (ix) any such petition or application is filed, or any such

<PAGE>
         Subsidiary, by any corporate act, consents thereto or acquiesces
         therein, or an order, judgment or decree is entered appointing any such

         effect for more than 60 days; or

         created thereunder for which the thirty day notice requirement has not
         been waived under the applicable regulations, or an event occurs
         requiring the Company or any ERISA Affiliate to provide security to an

         Code or in section 406 of ERISA, in connection with any ERISA Plan or
         any trust created thereunder; any notice of intent to terminate an
         ERISA Plan or ERISA Plans is filed under Title IV of ERISA by the
         Company or any ERISA Affiliate, any ERISA Plan administrator or any
         combination of the foregoing: any proceedings are instituted by the
         PBGC to terminate or to cause a trustee to be appointed to administer
         any ERISA Plan; any partial or complete withdrawal is made by the
         Company or an ERISA Affiliate from any Multiemployer Plan; any
         proceedings are instituted by a fiduciary of any ERISA 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

         ERISA) of any plan which is a Multiemployer Plan occurs; and each such
         instances in the aggregate, would, in the reasonable judgment of the
         Required Holder(s), more likely than not result in liability of the
         Company or any Code Affiliate or ERISA Affiliate to the IRS, the PBGC
         or an ERISA Plan in an aggregate amount exceeding $1,000,000; or

                                       22

                  (xiii) in the event the Company Notes are not outstanding, any
         order, judgment or decree is entered in any proceeding by a court of
         competent jurisdiction decreeing that the Plan, the ESOT or the ESOT
         Transaction has not been properly established or consummated, as the
         case may be (other than as specified in clause (b)(ii) of paragraph
         4A), 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 ESOT therefrom within 60 days of the time
         such order, judgment or decree first becomes appealable; or

         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 under which any Debt in aggregate principal amount
         exceeding $20,000,000 has been or may be issued (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 or holders) shall have caused, such
         obligation to become due prior to any stated maturity; or

                  (xv) a final judgment or judgments in an aggregate amount
         exceeding $1,000,000 is or are rendered against the Company or any
         Subsidiary and, within 60 days after entry thereof, such judgment(s)
         are not discharged or execution thereof stayed pending appeal, or
         within 60 days after the expiration of any such stay, such judgment(s)
         are not discharged;

than (a) if such event is an Event of Default specified in clause (vii), (viii)
or (ix) 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 ESOT, and (b) if such event is an Event of Default
specified in any other clause of this paragraph 9A, the holder or holders of at
least 25% 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 ESOT,
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 ESOT, 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 Market 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 ESOT, provided that the Market 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 (vi), inclusive,
and clauses (xii), (xiii), (xiv) and (xv) of this paragraph 9A, (y) the holder
or holders making such declaration shall have given to the Company and the ESOT,
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 or more of the Events
of Default so identified shall be

                                       23
<PAGE>

continuing at the time of such declaration. Nothing in this Agreement shall
permit (i) a transfer of assets of the ESOT to any Person in excess of the
amount permitted under Treasury Regulation Section 54.4975-7(b)(6), or (ii) if a
holder of any Note is a disqualified person within the meaning of Section 4975
of the Code of the Regulations thereunder, the transfer of assets of the ESOT
to such holder except upon the failure of the ESOT to make payment of regularly
scheduled payments of principal 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 the 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 statute 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 Required Holder(s) may, by written notice to the Company and the ESOT and to
the 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 Notes which have become due
solely by any such declaration of acceleration, shall have been cured or
expressly waived by the Required Holder(s). No rescission or annulment referred
to above shall affect any subsequent Default or any right, power or remedy
arising out of such subsequent Default.

                  10. REPRESENTATIONS AND WARRANTIES. The Company and, in the
case of paragraphs 10N (b) and (d) and 100, ESOT, as to the ESOT, represent and
warrant that:

                  10A. ORGANIZATION; CORPORATE AUTHORITY. The Company and each
of its Subsidiaries are corporations duly organized and validly existing in good
standing under the laws of their respective states of incorporation; 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 consolidated financial
position, shareholders' equity or results of operations of the Company and its
Subsidiaries taken as a whole; and 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 consolidated financial position, shareholders' equity 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 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
(subject, as to enforceability, to the effect of bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting the enforcement of
creditors' rights generally and the application of general principles of
equity.)

                  10B. FINANCIAL STATEMENTS; SEC REPORTS. The Historical
Financial Statements (a) are complete and correct in all material respects, (b)
have been prepared in conformity with generally accepted accounting principles
applied on a consistent basis and show all liabilities, direct or contingent, of
the Company and its Subsidiaries required to be shown in accordance with such
principles, and (c) present fairly, in all material respects, the consolidated
financial position of the Company and its Subsidiaries at the dates indicated
and their results of operations and cash flows for the periods indicated. The
SEC Reports have been prepared in conformity in all material respects with the
rules and regulations of the Commission applicable thereto, and, in accordance
with such rules and regulations, describe the business conducted by the Company
and its Subsidiaries and the properties owned and operated in connection
therewith. The Historical Financial Statements, the SEC Reports, and all other
documents and reports delivered by or on behalf of the Company to you in
connection with the transactions contemplated by this Agreement (which other
documents and reports are described in the Company's letter to you dated the
date hereof), are herein collectively called the "Disclosure Documents". The
Disclosure Documents did not, as of their respective dates, and taken as a
whole, and this Agreement does not as of the date hereof 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 expected to
(so far as the Company can now foresee) materially adversely affect the
consolidated financial position, shareholders' equity or results of operation of
the Company and its Subsidiaries taken as a whole which has not

                                       24
<PAGE>
been set forth in this Agreement or in the Disclosure Documents. Neither the
Company nor any of its Subsidiaries has sustained since March 31, 1989 any loss
or interference with its business from fire, explosion, flood or other calamity,
whether or not covered by insurance, or from any labor dispute or court or
governmental action, order or decree which is material to the Company and its
consolidated Subsidiaries considered as a whole, otherwise than as set forth or
contemplated in the Disclosure Documents; and, since the respective dates as of

such fees shall be paid by it and that it will hold you harmless from any claim,
demand or liability for broker's or finder's fees or commissions alleged to have
been incurred in connection with this transaction.

            10I.  MARGIN REGULATIONS; ETC. Neither the Company nor the ESOT

company" of a "holding company", as such terms are defined in the Public Utility
Holding Company Act of 1935, as amended.

            10L.  GOVERNMENTAL CONSENTS, ETC. No consent, approval or

delivery of this Agreement or the Plan Documents or the consummation of the
transactions contemplated hereby and thereby except the filing of the Plan
Documents with the IRS as contemplated by paragraph 5F.

            10M.  ERISA. (a) Prohibited Transactions. Neither the Company nor
any ERISA Affiliate has engaged in a transaction in connection with which the
Company could be subject to a material liability for either a civil penalty
assessed pursuant to section 502(i) of ERISA or a tax imposed by section 4975 of
the Code.

            (b)   ERISA Plan Termination; Material Liabilities. There has been
no termination of an ERISA Plan or trust created under any ERISA Plan that would
give rise to a material liability to the PBGC on the part of the Company or an
ERISA Affiliate. No material liability to the PBGC has been or is expected by
the Company to be incurred with respect to any ERISA Plan by the Company or an
ERISA Affiliate. The PBGC has not instituted proceedings to terminate any ERISA
Plan which is maintained or is to be maintained by the Company or an ERISA
Affiliate. There exists no condition or set of circumstances which presents
material risk of termination or partial termination of any ERISA Plan by the
PBGC or restoration of any ERISA Plan heretofore terminated. The Company and
each Code Affiliate is current with all premiums to the PBGC.

            (c)   Accumulated Funding Deficiency. Full payment has been made of
all amounts which are required under the terms of each ERISA Plan to have been
paid as contributions to such ERISA Plan as of the last day of the most recent
fiscal year of such ERISA Plan ended on or before the date of this Agreement,
and no accumulated funding deficiency (as defined in section 302 of ERISA and
section 412 of the Code), whether or not waived, exists with respect to any
ERISA Plan or any employee pension benefit plan maintained by the Company or a
Code Affiliate. The Company and each Code Affiliate is current with all required
installments under section 412(m) of the Code.

            (d)   Relationship of Benefits to Pension Plan Assets. The current
value of the benefit liabilities (as defined in section 4001(a)(16) of ERISA) of
each ERISA Plan does not exceed the fair market value of the assets of such
ERISA Plan. Neither the Company nor any

                                       27
<PAGE>
Code Affiliate is required to provide security to an ERISA Plan or an employee
pension benefit plan maintained by a Code Affiliate under section 401(a)(29) of
the Code. No lien under section 412(n) of the Code or sections 312(f) or 4068 of
ERISA has been or is reasonably expected by the Company to be imposed on the
assets of the Company or any ERISA Affiliate.

            (e)   Withdrawal Liability. Neither the Company nor any ERISA
Affiliate has made a complete or partial withdrawal (or a reduction in
contribution base units which if continued would result in a partial withdrawal)
from a Multiemployer Plan which has resulted in, or is reasonably expected by
the Company to result in, a material withdrawal liability.

            (f)   Compliance with ERISA. All employee pension benefit plans (as
defined in section 3(2) of ERISA) maintained by the Company or an ERISA
Affiliate which are intended to be "qualified" are "qualified" under section
401(a) of the Code. All employee benefit plans (as defined in section 3(3) of
ERISA) maintained by the Company or an ERISA Affiliate have been administered
substantially in compliance with ERISA and the applicable provisions of the
Code. There are no pending issues before the IRS or any court of competent
jurisdiction related to the qualification of the Plan except for the filing of
the Plan and the ESOT with the IRS as contemplated by paragraph 5F. Neither the
Company nor any Code Affiliate has any material liability under the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended.

            (g)   Execution of Agreement. The execution and delivery of this
Agreement and the consummation of the transactions contemplated by this
Agreement will not involve any transaction which is subject to the prohibitions
of section 406 of ERISA or in connection with which a tax could be imposed
pursuant to section 4975 of the Code. The representation by the Company in the
preceding sentence is made in reliance upon and subject to the accuracy of your
representation in paragraph 11 as to the source of funds used to pay the
purchase price of the Notes.

            10N.  THE PLAN. (a) The Plan is an "employee stock ownership plan"
within the meaning of section 4975(e)(7) of the Code and is qualified under
section 401(a) of the Code. The ESOT has been duly constituted in accordance
with the Trust Agreement, is validly existing and is tax-exempt under section
501(a) of the Code.

            (b)   The Trustee has the requisite power and authority to own the
properties and assets of the Trust. The execution, delivery and performance of
this Agreement and the consummation of the ESOT Transaction by the parties
thereto will not involve any transaction which is subject to the prohibitions of
section 406 of ERISA and will not otherwise constitute a violation of, or give
rise to any liability under, any other provision of Title I of ERISA or section
4975 of the Code, provided, however, that in making this representation the ESOT
has relied on (i) the Company's determination that the interest rate on the
Notes is reasonable and (ii) the report by Houlihan Lokey Howard & Zukin Inc. as
to whether the purchase of the Employer Capital Stock is for no more than
adequate consideration; and in this regard the Trustee has exercised its powers
in manner consistent with Part 4 of Title I of ERISA.

            (c)   Under current law, the issuance and sale of the Notes
hereunder to you by the ESOT would qualify as a "securities acquisition loan"
within the meaning of section 133 of the Code and, as a result thereof, 50% of
the interest on the Notes would be excludible from the

                                       28
<PAGE>
gross income of any holder of the Notes for Federal income tax purposes,
assuming that such holder is a Qualified Holder. (Purchaser acknowledges that
two bills, H.R. 2572 and S. 1171, have been introduced to Congress which, if
enacted in the form in which they were introduced, would repeal such exclusion
as applicable to interest on the Notes.)

            (d)   Neither the Plan nor the ESOT has incurred any Debt and, as of
the Closing, neither will have incurred any Debt other than Debt represented by
the Notes. The ESOT Transaction as of the date hereof has been, and after giving
effect to the transactions contemplated hereby will be, duly and validly
consummated and all Plan Documents are and will be legal, valid, binding and
enforceable obligations of the respective parties thereto (subject, as to
enforceability, to the effect of bankruptcy, insolvency, reorganization,
moratorium and other similar laws affecting the enforcement of creditors' rights
generally and the application of general equitable principles).

            (e)   The Plan and the ESOT have been established by the Company for
a valid corporate purpose. The Company and the ESOT have delivered to you true
and correct copies of the Plan Documents and all other documents having the
legal effect of governing the terms or administration of the Plan and the ESOT.

            10O.  REPRESENTATION AS TO THE TRUSTEE. (a)(i) The Trustee has all
requisite power and authority to execute and deliver and to perform all of the
obligations of the ESOT under this Agreement and the Notes and to carry out the
ESOT Transaction; (ii) the execution, delivery and performance by the Trustee of
this Agreement and the Notes and the consummation by the ESOT of the ESOT
Transaction will not violate any provision of any law, rule, regulation
(including, without limitation, Regulation X of the Board of Governors of the
Federal Reserve System), order, writ, judgment, injunction, decree,
determination or award presently in effect having applicability to the Trustee;
(iii) this Agreement constitutes, and the Notes when delivered hereunder will
constitute, legal, valid and binding obligations of the ESOT enforceable against
the ESOT in accordance with their terms except: (A) such enforcement may be
subject to bankruptcy, insolvency, reorganization, moratorium or other similar
laws now or hereafter in effect relating to creditors rights, and (B) the remedy
of specific performance and injunctive and other forms of equitable relief may
be subject to equitable defenses and to the discretion of the court before which
any proceeding therefor may be brought; and (iv) there are no actions, suits or
proceedings pending or, to the best knowledge of the Company or the ESOT,
threatened against or affecting the ESOT or its properties before any court or
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, which (A) draw into question the validity of the Trust
Agreement, this Agreement, the Notes or the ESOT Transaction or (B) if
determined adversely to the ESOT, would materially adversely affect the ability
of the Trustee to perform its obligations under the Trust Agreement or of the
ESOT to perform its obligation under this Agreement or the Notes or of any of
them to consummate the ESOT Transaction.

            (b)   The following representations and warranties are made only by
the Bank in its individual capacity and not by the Company or the ESOT: The
Bank, in its individual capacity, represents and warrants that (i) the Bank in a
national banking association with corporate trust powers duly organized, validly
existing and in good standing under the laws of the United States and has all
requisite power and authority, corporate and otherwise, to conduct

                                       29
<PAGE>
its business and to execute and deliver, and to perform all its obligations
under, the Trust Agreement; (ii) the Bank is not in default under any provision
of any law, rule, regulation (including, without limitation, Regulation X of the
Board of Governors of the Federal Reserve System), order, writ, judgment,
injunction, decree, determination or award presently in effect having
applicability to the Bank or any indenture or loan or credit agreement or any
other material agreement, lease or instrument to which the Bank is a party or by
which it or its properties are bound or affected, which default would materially
affect the ability of the Bank to perform its obligations under the Trust
Agreement; and (iii) the execution, delivery and performance by the Bank of the
Plan Documents, this Agreement and the Notes and the consummation by the ESOT of
the ESOT Transaction do not and will not violate any provisions of the articles
of association or by-laws of the Bank.

            10P.  POLLUTION AND OTHER REGULATIONS. (a) Except as otherwise
previously disclosed to you in writing, the Company is in compliance in all
respects with all laws and regulations, including, without limitation, those
relating to equal employment opportunity and employee safety in all
jurisdictions in which it is presently doing business except where the failure
to do so would not adversely affect the business, condition (financial or other)
or operations of the Company and its Subsidiaries taken as a whole.

            (b)   Except as otherwise previously disclosed to you in writing,
the Company and its Subsidiaries, and the plants and sites of each, have
complied in all respects with all Federal, state, local and regional statutes,
ordinances, orders, judgments, rulings and regulations relating to any matters
of pollution or of environmental regulation or control except, in any such case,
where such failure to comply would not result in a material adverse effect on
the business, condition (financial or other) or operations of the Company and
its Subsidiaries, taken as a whole. Without limiting the generality of the
preceding sentence, neither the Company nor any of its Subsidiaries has received
notice of or has actual knowledge of any actual or claimed or asserted failure
so to comply which alone, or together with any other such failure is material
and would result in a material adverse effect on the business, condition
(financial or other) or operations of the Company and its Subsidiaries, taken as
a whole. Neither the Company nor any of its Subsidiaries nor their plants or
other sites manage, generate or dispose of, or during their respective periods
of use, ownership, occupancy or operation have managed, generated, released or
disposed of, any hazardous wastes, hazardous substances, hazardous materials,
toxic substances or toxic pollutants, as those terms are used or defined in the
Resource Conservation and Recovery Act, the Comprehensive Environmental Response
Compensation and Liability Act, the Hazardous Materials Transportation Act, the
Toxic Substance Control Act, the Clean Air Act and the Clean Water Act, in
material violation of or in a manner which would result in liability under such
statutes or any regulations promulgated pursuant thereto or any other applicable
law except where such noncompliance or liability would not result in a material
adverse effect on the business, condition (financial or other) or operations of
the Company and its Subsidiaries, taken as a whole. The foregoing representation
is based in its entirety upon: (i) current interpretations and enforcement
policies utilized by governmental agencies charged with enforcement of the legal
requirements within the scope of the representation; and (ii) current levels of
scientific knowledge concerning the detection of, and the health and
environmental risk associated with the discharge of, small quantities of
pollutants regulated pursuant to the legal requirements within the scope of the
representation.

                  computing any Federal tax (including without limitation, by

                  changing the provisions of Section 812(g) of the Code),

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 interests, only one counsel's fees and
disbursements shall be so reimbursed) in connection therewith (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 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 and (iv) all expense associated with the rating of the Notes by
the National Association of Insurance Commissioners, including the costs of
obtaining any "PPN Number" required therefor.

            14C.  CONSENT TO AMENDMENTS. (a) This Agreement may be amended with
the consent of both the Company and the ESOT, and with such consent the Company
or the ESOT, 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 Holder(s), except
that, without the written consent of the older 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

                                       42
<PAGE>
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 4A, 4B or 4D or reduce the proportion of the principal amount of
the Notes required with respect to any consent. 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 marked to indicate such
consent, but any Notes issued thereafter may bear a notation referred to any
such consent. No course of dealing between the ESOT 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 ESOT 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 ESOT or the Company, as the case may be, and shall be afforded an
opportunity of considering the same and shall be supplied by the ESOT 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 ESOT or the Company, as the case maybe, 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 ESOT 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 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 $10,000,000, except as may be necessary to reflect any
principal amount not evenly divisible by $1,000,000. The ESOT shall keep or
cause to be kept at its principal office or at the offices of its designated
agent (the "ESOT Agent"), which shall initially be the Trust Company or such
other ESOT Agent as the ESOT 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. The Company and any registered holder of a
Note shall be entitled, upon its written request, to receive from the ESOT 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 principal office of the ESOT 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 ESOT Agent. Whenever any Notes are so surrendered
for exchange, the ESOT 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 enforced, 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. As a
condition of

                                       43
<PAGE>
registering nay transferred Note in the name of the transferee, the ESOT may
require a certificate of such transferee certifying that the transferee is not
acquiring the transferred Note with a view to or for sale in connection with any
distribution which would violate the Securities Act. 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 form 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 ESOT 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
of registration of transfer, the ESOT 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 ESOT 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.
