prior to the Change of Control Prepayment Date, of its acceptance or rejection
of such offer, (iv) inform such holder that, upon its receipt of the Company
Notice, failure to reject such offer in writing on or before the 10th day prior

offer and (v) set forth the respective names and addresses of, and principal
amounts of the Notes held by, any other holders of the Notes then outstanding.
Not less than two business days prior to the Change of Control Prepayment Date,
the Company shall provide each holder of the Notes with a reasonably detailed

                  The Company covenants and agrees that it will on the Change of
Control Prepayment Date prepay all of the Notes held by each holder of the Notes
then outstanding which has accepted the prepayment offer in accordance with this
Section 2.3, by payment of the principal amount of such Notes, together with
interest accrued on the unpaid principal amount of such Notes to the Change of
Control Prepayment Date and the then applicable Make-Whole Amount.

SECTION 5. COMPANY COVENANTS.

the property or business of the Company or such Restricted Subsidiary, all trade
accounts payable in accordance with usual and customary business terms, and all
claims for work, labor or materials, which if unpaid might become a Lien upon
any property of the Company or such Restricted Subsidiary; provided the Company
or such Restricted Subsidiary shall not be required to pay any such tax,
assessment, charge, levy, account payable or claim if (i) the validity,
applicability or amount thereof is being contested in good faith by appropriate

engaged in by the Company and its Restricted Subsidiaries would be substantially
changed from the storage, transmission and sale of water for domestic,
industrial and commercial uses, and activities related thereto.

Company or a Restricted Subsidiary of any business entity then owning such fixed
assets, whether or not such existing Liens were given to secure the payment of
the purchase price of the fixed assets to which they attach so long as they were

Restricted Subsidiary

for a period not exceeding 12 months prior to the date of transfer, or (ii) the

Payments"), if, after giving effect thereto, either (i) an Event of Default
shall have occurred and be continuing or (ii) the sum of (x) the aggregate
amount of Restricted Payments made during the period from and after December 31,
1990 to and including the date of the making of the Restricted Payment in
question, plus (y) the aggregate amount of all Restricted investments made by
the Company or any Restricted Subsidiary during said period would exceed 50% of
Consolidated Net Income for such period, computed on a cumulative basis for said
entire period after deducting all dividends paid on the 6% cumulative preferred
stock of the Company outstanding on the Closing Date (or if such Consolidated

                  The Company will not declare any dividend which constitutes a

the making of the Restricted Payment in question.

                  5.10. Investments. The Company will not, and will not permit

                  (c) Investments in direct obligations of the United States of

foregoing provisions of this Section 5.10), provided that (i) all such other
Investments shall have been made out of funds available for Restricted Payments
which the Company or any Restricted Subsidiary would then be permitted to make
in accordance with the provisions of Section 5.9 and (ii) after giving effect to
such other Investments, no Event of Default shall have occurred and be
continuing.

                  In valuing any Investments for the purpose of applying the
limitations set forth in this Section 5.10, such Investments shall be taken at

appreciation or depreciation therein, but less any amount repaid or recovered on
account of capital or principal.

                  For purposes of this Section 5.10, at any time when a
corporation becomes a Restricted Subsidiary, all Investments of such corporation
at such time shall be deemed to have been made by such corporation, as a

other evidence of Funded Debt or Current Debt of the Company gives any notice or
takes any other action with respect to a claimed default, the Company agrees to
give notice within three business days of such event to all holders of the Notes
then outstanding.

thereupon become, forthwith due and payable, without any presentment, demand,
protest or other notice of any kind, all of which are hereby expressly waived.
When any Event of Default described in paragraph (o) or (p) of Section 6.1 has

forthwith pay to the holders of the Notes the entire principal and interest
accrued on the Notes and, to the extent not prohibited by applicable law, an
amount as liquidated damages for the loss of the bargain evidenced hereby (and
not as a penalty) equal to the Make-Whole Amount, determined as of the date on
which the Notes shall so become due and payable. No course of dealing on the
part of the holder or holders of any Notes nor any delay or failure on the part
of any holder of Notes to exercise any right shall operate as a waiver of such
right or otherwise prejudice such holder's rights, powers and remedies. The
Company further agrees, to the extent permitted by law, to pay to the holder or
holders of the Notes all costs and expenses incurred by them in the collection
of any Notes upon any default hereunder or thereon, including reasonable
compensation to such holder's or holders' attorneys for all services rendered in

principal amount of the Notes then outstanding may, by written instrument filed
with the Company, rescind and annul such declaration and the consequences
thereof, provided that at the time such declaration is annulled and rescinded:

                  (a) no judgment or decree has been entered for the payment of
any monies due pursuant to the Notes or this Agreement;

                  (b) all arrears of interest upon all the Notes and all other
sums payable under the Notes and under this Agreement (except any principal,
interest or premium on the Notes which has become due and payable solely by
reason of such declaration under Section 6.3) shall have been duly paid; and

                  (c) each and every other Default and Event of Default shall
have been made good, cured or waived pursuant to Section 7.1;

and provided further, that no such rescission and annulment shall extend to or
affect any

subsequent Default or Event of Default or impair any right consequent thereto.

SECTION 7. AMENDMENTS, WAIVERS AND CONSENTS.

                  7.1. Consent Required. Any term, covenant, agreement or
condition of this Agreement may, with the consent of the Company, be amended or
compliance therewith may be waived (either generally or in a particular instance
and either retroactively or prospectively), if the Company shall have obtained
the consent in writing of the holders of at least 66-2/3% in aggregate principal
amount of outstanding Notes; provided that without the written consent of the
holders of all of the Notes then outstanding, no such amendment or waiver shall
be effective which will change (i) the time of payment (including any prepayment
required by Section 2.1) of the principal of or the interest on any Note or
change the principal amount thereof or change the rate of interest thereon, or
(ii) any of the provisions with respect to optional prepayments, or (iii) the
percentage of holders of the Notes required to consent to any such amendment or
waiver of any of the provisions of this Section 7 or Section 6.

outstanding, the Company will not 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 owned by it) shall be informed thereof by the Company and shall be
afforded the opportunity of considering the same and shall be supplied by the
Company with sufficient information to enable it to make an informed decision
with respect thereto. The Company will not, directly or indirectly, payor 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 any holder of Notes of any waiver or amendment of
any of the terms and provisions of this Agreement or the Notes unless such
remuneration is concurrently offered, on the same terms, ratably to the holders
of all Notes then outstanding.

                  7.3. Effect of Amendment or Waiver. Any such amendment or
waiver shall apply equally to all of the holders of the Notes and shall be
binding upon them, upon each future holder of any Note and upon the Company,
whether or not such Note shall have been marked to indicate such amendment or
waiver. No such amendment or waiver shall extend to or affect any obligation not
expressly amended or waived or impair any right consequent thereon.

Person, and (iii) all Guaranties by such Person of Funded Debt of others.

for deposit or collection) of such Person guaranteeing, or in effect
guaranteeing, any Indebtedness, dividend or other obligation of any other Person
(the "primary obligor") in any manner, whether directly or indirectly,
including, without limitation, all obligations incurred through an agreement,
contingent or otherwise, by such Person: (i) to purchase such Indebtedness or
obligation or any property or assets constituting security therefor, (ii) to
advance or supply funds (x) for the purchase or payment of such Indebtedness or
obligation, (y) to maintain working capital or other balance sheet condition or

payment of the Indebtedness or obligation, or (iv) otherwise to assure the owner
of the Indebtedness or obligation of the primary obligor against loss in respect
thereof. For the purposes of all computations made under this Agreement, a
Guaranty in respect of any Indebtedness for borrowed money shall be deemed to be
Indebtedness equal to the principal amount of such Indebtedness for borrowed
money which has been guaranteed, and a Guaranty in respect of any other
obligation or liability or any dividend shall be deemed to be Indebtedness equal
to the maximum aggregate amount of such obligation, liability or dividend.

                  "Guarantor" shall mean Barnstable Holding Co., Inc., a

which has been incurred in connection with the acquisition of property or
assets, (ii) obligations secured by any Lien upon property or assets owned by
such Person, even though such Person has not assumed or become liable for the
payment of such obligations, (iii) obligations created or arising under any
conditional sale or other title retention agreement with respect to property
acquired by such Person, notwithstanding the fact that the rights and remedies
of the seller, lender or lessor under such agreement in the event of default are
limited to repossession or sale of property, (iv) Capitalized Rentals and (v)
Guaranties of obligations of others of the character referred to in this
definition.

                  "Institutional Holder" shall mean any "qualified institutional

property, whether such interest is based on the common law, statute or contract,
and including but not limited to the security interest lien arising from a
mortgage, encumbrance, pledge, conditional sale or trust receipt or a lease,
consignment or bailment for security purposes. The term "Lien" shall include
reservations, exceptions encroachments, easements, rights-of-way, covenants,
conditions, restrictions, leases and other title exceptions and encumbrances

For the purposes of this Agreement, the Company or a Restricted Subsidiary shall
be deemed to be the owner of any property which it has acquired or holds subject
to a conditional sale agreement, Capitalized Lease or other arrangement pursuant
to which title to the property has been retained by or vested in some other
Person for security purposes and such retention or vesting shall constitute a
Lien.

                  "Make-Whole Amount" shall mean in connection with any
prepayment or acceleration of the Notes the excess, if any, of (i) the aggregate
present value as of the date of such prepayment of each dollar of principal
being prepaid (taking into account the application of such prepayment required
by Section 2.1) and the amount of interest (exclusive of interest accrued to the
date of prepayment) that would have been payable in respect of such dollar if
such prepayment had not been made, determined by discounting such amounts at the
Reinvestment Rate from the respective dates on which they would have been
payable, over (ii) 100% of the principal amount of the outstanding Notes being
prepaid. If the Reinvestment Rate is equal to or higher than 10.2%, the
Make-Whole Amount shall be zero. For purposes of any determination of the Make
Whole Amount;

                  "Reinvestment Rate" shall mean the arithmetic mean of the
yields under the respective headings "This Week" and "Last Week" published in
the Statistical Release under the caption "Treasury Constant Maturities" for the
maturity (rounded to the nearest month) corresponding to the Weighted Average
Life to Maturity of the principal being prepaid (taking into account the
application of such prepayment required by 52.1). If no maturity exactly
corresponds to such Weighted Average Life to Maturity, yields for the two
published maturities most closely corresponding to such Weighted Average Life to
Maturity shall be calculated pursuant to the immediately preceding sentence and
the Reinvestment Rate shall be interpolated or extrapolated from such yields on
a straight-line basis, rounding in each of such relevant periods to the nearest
month. For the purposes of calculating the Reinvestment Rate, the most recent
Statistical Release published prior to the date of determination of the
Make-Whole Amount shall be used.

                  "Statistical Release" shall mean the then most recently
published statistical release designated "H.15(519)" or any successor which is
published weekly by the Federal Reserve System and which establishes yields on
actively traded U.S. Government Securities

at the time of any determination hereunder, then such other reasonably
comparable index which shall be designated by the holders of 66-2/396 in
aggregate principal amount of the outstanding Notes.

                   "Weighted Average Life to Maturity" of the principal amount
of the Notes being prepaid shall mean, as of the time of any determination
thereof, the number of years obtained by dividing the then Remaining
Dollar-Years of such principal by the aggregate amount of such principal. The
term "Remaining Dollar-Years" of such principal shall mean the amount obtained
by (i) multiplying (x) the remainder of (1) the amount of principal that would
have become due on each scheduled payment date if such prepayment had not been
made, less (2) the amount of principal on the Notes scheduled to become due on
such date after giving effect to such prepayment and the application thereof in
accordance with the provisions of Section 2.1, by (y) the number of years
(calculated to the nearest one-twelfth) which will elapse between the date of
determination and such scheduled payment date, and (ii) totalling the products
obtained in (i).

                  "Minority Interests" shall mean any shares of stock of any
class of a Restricted Subsidiary (other than directors' qualifying shares as
required by law) that are not owned by the Company and/or one or more of its
Restricted Subsidiaries. Minority Interests shall be valued by valuing Minority
Interests constituting preferred stock at the voluntary or involuntary
liquidating value of such preferred stock, whichever is greater, and by valuing
Minority Interests constituting common stock at the book value of capital and
surplus applicable thereto adjusted, if necessary, to reflect any changes from
the book value of such common stock required by the foregoing method of valuing
Minority Interests in preferred stock.

                  "Multiemployer Plan" shall have the same meaning as in ERISA.

                   "Net Income Available for Fixed Charges" for any period shall
mean the sum of (i) Consolidated Net Income during such period plus (to the
extent deducted in determining Consolidated Net Income), (ii) all provisions for
any Federal, state or other income taxes made by the Company and its Restricted
Subsidiaries during such period and (iii) Fixed Charges of the Company and its
Restricted Subsidiaries during such period.

entity succeeding to any or all of its functions under ERISA.

                   "Person" shall mean an individual, partnership, corporation,
trust or unincorporated organization, and a government or agency or political
subdivision thereof.

                   "Plan" means a "pension plan," as such term is defined in
ERISA, established or maintained by the Company or any ERISA Affiliate or as to
which the Company or any ERISA Affiliate contributed or is a member or otherwise
may have any liability.

                  "Pro Forma Fixed Charges" for any period shall mean, as of the
date of any determination thereof, the maximum aggregate amount of Fixed Charges
which would have become payable by the Company and its Restricted Subsidiaries

Rentals) and the concurrent retirement of outstanding Funded Debt or Current
Debt or termination of any Capitalized Leases.

                  "Purchaser" shall have the meaning set forth in Section 1.1.

                  "Rentals" shall mean and include as of the date of any
determination thereof all fixed payments (including as such all payments which
the lessee is obligated to make to the lessor on termination of the lease or
surrender of the property) payable by the Company or a Restricted Subsidiary, as
lessee or sublessee under a lease of real or personal property, but shall be
exclusive of any amounts required to be paid by the Company or a Restricted
Subsidiary (whether or not designated as rents or additional rents) on account
of maintenance, repairs, insurance, taxes and similar charges. Fixed rents under
any so-called "percentage leases" shall be computed solely on the basis of the
minimum rents, if any, required to be paid by the lessee regardless of sales
volume or gross revenues.

corporation any corporation of which more than 5096 (by number of votes) of the

to elect a majority of the corporate directors (or Persons performing similar
functions).

                  "Wholly-owned" when used in connection with any Subsidiary
shall mean a Subsidiary of which all of the issued and outstanding shares of
stock (except shares required as directors' qualifying shares) and all Funded

Note which has been duly registered as hereinabove provided may transfer such
Note upon surrender thereof at the principal office of the Company duly endorsed
or accompanied by a written instrument of transfer duly executed by the
registered holder of such Note or its attorney duly authorized in writing.

                  The Person in whose name any registered Note shall be

Note initially delivered or of any Note substituted therefor pursuant to Section
9.1, this Section 9.2 or Section 9.3, and, upon surrender of such Note at its

the payment of a sum sufficient to cover any stamp tax or governmental charge
imposed upon such exchange or transfer.

satisfactory evidence thereof and no further indemnity shall be required as a

delay or failure on the part of the holder of any Note in the exercise of any
power or right shall operate as a waiver thereof; nor shall any single or

holder of any Note are cumulative to, and are not exclusive of, any rights or
remedies any such holder would otherwise have.

                  9.6. Notices. All communications provided for hereunder shall

         good standing under the laws of its jurisdiction of incorporation;

                  (b) has all requisite power and authority and all necessary

                  (c) does not transact business or own or lease property in any
         state other than The Commonwealth of Massachusetts so as to require the
         Company to be qualified or licensed as a foreign corporation in any

                  3. Business and Property. You have heretofore been furnished

                  4. Financial Statements. (a) The balance sheets of the Company
as of December 31 in each of the years 1985 to 1989, both inclusive, and the

                                    EXHIBIT C
                               (to Note Agreement)

                  5. Indebtedness. Annex 1 attached hereto correctly describes
all Current Debt, Funded Debt, Capitalized Leases and Long-Term Leases of the
Company outstanding on February 28, 1991.

                  6. Full Disclosure. Neither the financial statements referred
to in paragraph 4 hereof nor the Agreement, the Report or any other written
statement furnished by the Company to you in connection with the negotiation of
the sale of the Notes, contains any untrue statement of a material fact or omits
a material fact necessary to make the statements contained therein or herein not
misleading. There is no fact peculiar to the Company which the Company has not
disclosed to you in writing which materially affects adversely nor, so far as
the Company can now foresee, will materially affect adversely the properties,
business, prospects, profits or condition (financial or otherwise) of the
Company.

                  7. Pending Litigation. Except as disclosed in Annex 2 attached
hereto, there are no proceedings pending or, to the knowledge of the Company,
threatened against or affecting the Company in any court or before any
governmental authority or arbitration board or tribunal which involve the
possibility of materially and adversely affecting the properties, business,
prospects, profits or condition (financial or otherwise) of the Company.

                  8. Title to Properties. The Company has good and marketable
title in fee simple (or its equivalent under applicable law) to all material
parcels of real property and has good title to all the other material items of
property it purports to own, including that reflected in the most recent balance
sheet referred to in paragraph 4 hereof, except as sold or otherwise disposed of
in the ordinary course of business and except for Liens permitted by the
Agreement.

                  9. Patents and Trademarks. The Company owns or possesses all
the patents, trademarks, trade names, service marks, copyright, licenses and
rights with respect to the foregoing necessary for the present and planned
future conduct of its business, without any known conflict with the rights of
others.

                  10. Sale is Legal and Authorized. The sale of the Notes and
compliance by the Company with all of the provisions of the Agreement and the
Notes

                  (a) are within the corporate powers of the Company;

                  (b) will not violate any provisions of any law or any order of
any court or governmental authority or agency and will not conflict with or
result in any breach of any of the terms, conditions or provisions of, or
constitute a default under the Charter or By-laws of the Company or any
indenture or other agreement or instrument to which the Company is a party or by
which it may be bound or result in the imposition of any Liens or encumbrances
on any property of the Company; and

                  (c) have been duly authorized by proper corporate action on
the part of the Company (no action by the stockholders of the Company being
required by law, by the Charter or By-laws of the Company or otherwise),
executed and delivered by the Company and the Agreement and the Notes constitute
the legal, valid and binding obligations, contracts and agreements of the
Company enforceable in accordance with their respective terms.

                  11. No Defaults. No Default or Event of Default has occurred
and is continuing. The Company is not in default in the payment of principal or
interest on any Funded Debt or Current Debt and is not in default under any
instrument or instruments or agreements under and subject to which any Funded
Debt or Current Debt has been issued and no event has occurred and is continuing
under the provisions of any such instrument or agreement which with the lapse of
time or the giving of notice, or both, would constitute an event of default
thereunder.

                  12. Governmental Consent. Except for the approval of the
Department, which approval has been obtained and is in full force and effect, no
approval, consent or withholding of objection on the part of any regulatory
body, state, Federal or local, is necessary in connection with the execution and
delivery by the Company of the Agreement or the Notes or compliance by the
Company with any of the provisions of the Agreement or the Notes. The period for
the appeal of the order of the Department has been exhausted and no appeals have
been made in such period. Such order contains no burdensome restrictions on the
Company and authorizes the issue and sale of the Notes upon terms not
inconsistent with the Agreement.

                  13. Taxes. All tax returns required to be filed by the Company
in any jurisdiction have, in fact, been filed, and all taxes, assessments, fees
and other governmental charges upon the Company or upon any of its properties,
income or franchises, which are shown to be due and payable in such returns have
been paid. For all taxable years ending on or before December 31, 1986, the
Federal income tax liability of the Company has been satisfied and either the
period of limitations on assessment of additional Federal income tax has expired
or the Company has entered into an agreement with the Internal Revenue Service
closing conclusively the total tax liability for the taxable year. The Company
does not know of any proposed additional tax assessment against it for which
adequate provision has not been made on its accounts, and no material
controversy in respect of additional Federal or state income taxes due since
said date is pending or to the knowledge of the Company threatened. The
provisions for taxes on the stocks of the Company are adequate for all open
years, and for its current fiscal period.

                  14. Use of Proceeds. The net proceeds from the sale of the
Notes will be used to repay bank borrowings and for other corporate purposes.
None of the transactions contemplated in the Agreement (including, without
limitation thereof, the use of proceeds from the issuance of the Notes) will
violate or result in a violation of Section 7 of the Securities Exchange Act of
1934, as amended, or any regulation issued pursuant thereto, including, without
limitation, Regulations G, T and X of the Board of Governors of the Federal
Reserve System, 12 C.F .R., Chapter II. The Company does not own or intend to
carry or purchase any "margin stock" within the meaning of said Regulation G.
None of the proceeds from the sale of the Notes will be used to purchase, or
refinance any borrowing the proceeds of which were used to purchase, any
"security" within the meaning of the Securities Exchange Act of 1934, as
amended.

                  15. Private Offering. Neither the Company, directly or
indirectly, nor any agent on its behalf has offered or will offer the Notes or
any similar Security or has solicited or will solicit an offer to acquire the
Notes or any similar Security from or has otherwise approached or negotiated or
will approach or negotiate in respect of the Notes or any similar Security with
any Person other than the Purchaser and not more than one other institutional
investor, which was offered a portion of the Notes at private sale for
investment. Neither the Company, directly or

indirectly, nor any agent on its behalf has offered 0: will offer the Notes or
any similar Security or has solicited or will solicit an offer to acquire the
Notes or any similar Security from any Person so as to bring the issuance and
sale of the Notes within the provisions of Section 5 of the Securities Act of
1933, as amended.

                  16. ERISA. The consummation of the transactions provided for
in the Agreement and compliance by the Company with the provisions thereof and
the Notes issued thereunder will not involve any prohibited transaction within
the meaning of ERISA or Section 4975 of the Internal Revenue Code of 1986, as
amended. Each plan complies in all material respects with all applicable
statutes and governmental rules and regulations, and (a) no Reportable Event has
occurred and is continuing with respect to any Plan, (b) neither the Company nor
any ERISA Affiliate has withdrawn from any Plan or Multiemployer Plan or
instituted steps to do so, and (c) no steps have been instituted to terminate
any Plan. No condition exists or event or transaction has occurred in connection
with any Plan which could result in the incurrence by the Company or any ERISA
Affiliate of any material liability, fine or penalty. No Plan maintained by the
Company or any ERISA Affiliate, nor any trust created thereunder, has incurred
any "accumulated funding deficiency" as defined in Section 302 of ERISA. Neither
the Company nor any ERISA Affiliate has any contingent liability with respect to
any post-retirement "welfare benefit plan" (as such term is defined in ERISA)
except as has been disclosed to the Purchaser.

                  17. Compliance with Law. The Company (a} is not in violation
of any law, ordinance, franchise, governmental rule or regulation to which it is
subject; or (b) has not failed to obtain any license, permit, franchise or other
governmental authorization necessary to the ownership of its property or to the
conduct of its business, which violation or failure to obtain would materially
adversely affect the business, prospects, profits, properties or condition
(financial or otherwise) of the Company, or impair the ability of the Company to
perform its obligations contained in the Agreement or the Notes. The Company is
not in default with respect to any order of any court or governmental authority
or arbitration board or tribunal.

                  18. Compliance with Environmental Laws. Except as disclosed in
Annex 2 attached hereto, the Company is not in violation of any applicable
Federal, state, or local laws, statutes, rules, regulations or ordinances
relating to public health, safety or the environment, including, without
limitation, relating to releases, discharges, emissions or disposals to air,
water, land or ground water, to the withdrawal or use of ground water, to the
use, handling or disposal of polychlorinated biphenyls (PCB's), asbestos or urea
formaldehyde, to the treatment, storage, disposal or management of hazardous
substances (including, without limitation, petroleum, crude oil or any fraction
thereof, or other hydrocarbons), pollutants or contaminants, to exposure to
toxic, hazardous or other controlled, prohibited or regulated substances which
violation could have a material adverse effect on the business, prospects,
profits, properties or condition (financial or otherwise) of the Company. The
Company does not know of any liability or class of liability of the Company
under the Comprehensive Environmental Response, Compensation and Liability Act
of 1980, as amended (42 U.S.C. Section 9601 et seq.), or the Resource
Conservation and Recovery Act of 1976, as amended (42 U.S.C. Section 6901 et
seq.).

                  19. Franchises and Permits. The Company holds valid and
subsisting certificates of convenience and necessity, grants, franchises,
licenses, permits, consents, orders of governmental and regulatory authorities
and easements, free from unduly burdensome restrictions, required for the
maintenance and operation of its properties and business in the territories now
served by it and they enable it to carry on the business now being conducted by
it.

                  20. Investment Company Act. The Company is not, and is not
directly or indirectly controlled by or acting on behalf of any person which is,
an "investment company" within the meaning of the Investment Company Act of
1940, as amended.

provisions hereof by any Noteholder, any requirement of diligence or promptness
on the part of any Noteholder in the enforcement of rights under the provisions

Noteholder to proceed first against the Company. The obligations of the
Guarantor hereunder shall be unconditional irrespective of the genuineness,
validity, regularity or enforceability of the Note Agreement or of the Notes or
of any other circumstance which might otherwise constitute a legal or equitable
discharge of a surety or guarantor. The obligations of the Guarantor hereunder
shall not be affected by:

      (a) the recovery of any judgment against the Company, or by the levy of
any writ or process of execution under any such judgment, or by any action or
proceeding taken by any Noteholder, either under the Notes or under the Note
Agreement for the enforcement thereof, or hereof, or in the exercise of any

corporation or corporations or any sale, lease or other disposition of the

corporation, or

      (d) any other act or delay or failure to act, or by any other thing, which
mayor might in any manner or to any extent vary the risk of the Guarantor
hereunder;

it being the purpose and intent of the parties hereto that the obligations of
the Guarantor hereunder shall be absolute and unconditional under any and all
circumstances, and shall not be discharged except by payment as herein provided,
and then only to the extent of such payment or payments.

SECTION 4. COLLECTION EXPENSES.

            In the event that the Guarantor shall be required to make any
payment to any Noteholder pursuant to this Agreement, it shall, in addition to
such payment, pay to such Noteholder such further amount as shall be sufficient
to cover the costs and expenses of collection, including a reasonable
compensation to attorneys, and any expenses or liabilities incurred by any
Noteholder hereunder. The covenants contained in this Agreement may be enforced
by any Noteholder.

SECTION 5. NO SUBROGATION UNTIL PAYMENT IN FULL.

            No payment by the Guarantor pursuant to the provisions hereof to any
Noteholder shall entitle the Guarantor, by subrogation to the rights of the
holders of the Notes in respect of which such payment is made or otherwise, to
any payment by the Company or out of the property of the Company, except after
payment in full of the entire principal of and premium, if any, and interest on

Funded Debt shall have a fixed maturity date and shall become due and payable
upon the sale of any real property owned by Barlaco.

            (b) Any corporation which becomes a Significant Subsidiary after the
date hereof shall for all purposes of this Section 7.3 be deemed to have

      and its Significant Subsidiaries.

            (d) As used in this Section 7.8, a sale, transfer or other
disposition shall be deemed to be more than an "insubstantial part" of the
