                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.   CONSOLIDATED FINANCIAL STATEMENTS
     
     In the opinion of management, the accompanying unaudited consolidated
     financial statements contain all adjustments necessary to present fairly,
     in accordance with generally accepted accounting principles, the Company's
     financial position, results of operations and cash flows for the interim
     periods presented. Such adjustments consisted of only normal recurring
     items. The results of operations for the interim periods shown in this
     report are not necessarily indicative of results for any future interim
     period or for the entire year. These consolidated financial statements do
     not include all disclosures associated with annual financial statements and
     accordingly should be read in conjunction with the consolidated financial
     statements and notes thereto included in the Company's Annual Report on
     Form 10K.

2.   BASIS OF PRESENTATION

     For periods prior to November 13, 1996, the accompanying consolidated
     financial statements represent the consolidated results and financial
     position of AMTROL Inc. and Subsidiaries (the Predecessor). On November 13,
     1996, the Predecessor merged with AMTROL Acquisition, Inc., a wholly-owned
     subsidiary of AMTROL Holdings Inc., a Delaware corporation organized by The
     Cypress Group L.L.C. as more fully described in Note 3 (the Merger).
     Financial statements for periods subsequent to November 12, 1996 represent
     the consolidated financial statements of AMTROL Inc. and Subsidiaries (the
     Successor) after giving effect to the Merger. References to the Company
     refer to the Predecessor prior to the Merger and the Successor post-Merger.

3.   MERGER AND FINANCING

     AMTROL Acquisition Inc. ("Acquisition") and AMTROL Holdings Inc.
     ("Holdings") were formed by The Cypress Group L.L.C. ("Cypress") in 1996 to
     effect the acquisition of all of the outstanding common stock of the
     Predecessor through the Merger of Acquisition with and into the Successor.
     Upon consummation of the Merger on November 13, 1996, all of the
     outstanding common stock of Acquisition was converted into common stock of
     the Successor and the Successor became a wholly-owned subsidiary of
     Holdings. The Successor, as the surviving entity, continues to be named
     AMTROL Inc. Holdings has no other material assets, liabilities or
     operations other than those that result from its ownership of the common
     stock of the Successor.


                                                                             (5)

                                   (UNAUDITED)


3.   MERGER AND FINANCING (CONT'D.)


     The Merger has been accounted for as a purchase transaction effective as of
     November 13, 1996, in accordance with Accounting Principles Board Opinion
     No. 16, Business Combinations, and EITF Issue No. 88-16, Basis in Leveraged
     Buyout Transactions and, accordingly, the consolidated financial statements
     for the periods subsequent to November 12, 1996 reflect the purchase price,
     including transaction costs, allocated to tangible and intangible assets
     acquired and liabilities assumed, based on their estimated fair values as
     of November 12, 1996, which may be revised at a later date. The excess of
     the purchase price over the fair value of net assets acquired has been
     allocated to goodwill.

4.   ACQUISITION

     On June 30, 1997, the Company entered into a Promissory Agreement and a
     Complementary Document to the Promissory Agreement (collectively, the
     "Purchase Agreements") to acquire all the outstanding capital shares of
     Petroleo Mecanica Alfa, S.A., a corporation organized under the laws of
     Portugal ("Alfa").

     Alfa is a leading designer and manufacturer of reusable steel gas cylinders
     used for heating and refrigerant gases and maintains a production facility
     in Guimaraes, Portugal. Following the Acquisition, AMTROL will integrate
     Alfa into its existing business of manufacturing and distributing water and
     HVAC systems. This will provide a significant low cost manufacturing base
     for AMTROL products for distribution in Europe and the Far East.

     Under the Purchase Agreements the Company agreed to purchase Alfa for an
     aggregate purchase price of $25,500,000 (in United States dollars) and 
     assumed immediate management control of Alfa (the "Acquisition").
     Accordingly, the consolidated balance sheet of AMTROL as of July 5, 1997
     reflects the balances of Alfa as of such date. AMTROL paid $20 million of
     the purchase price on June 30, 1997 from borrowings out of availability
     under AMTROL's existing credit facility. The balance of $5.5 million, which
     is reflected in Other Non-current Liabilities on the balance sheet, is
     expected to be paid in December 1997 and will be funded by cash provided
     from working capital. The Acquisition is subject to the filing and approval
     requirements imposed by Portuguese laws governing concentration of
     industries and free competition.

                                                                             (6)

5.   USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

6.   SIGNIFICANT ACCOUNTING POLICIES

     GOODWILL

     Goodwill represents the excess of purchase price over the fair value of net
     assets acquired in connection with the Merger (approximately $146 million)
     and the Alfa Acquisition (approximately $22 million) and is included in
     other assets. Goodwill is being amortized over 40 years.

     INCOME TAXES

     The Company utilizes an asset and liability approach to determine income
     tax liabilities in accordance with SFAS No. 109. The standard recognizes
     tax assets and liabilities for the cumulative effect of all temporary
     differences between financial statement carrying amounts and the tax basis
     of assets and liabilities. The standard also requires the adjustment of
     deferred tax liabilities or assets for an enacted change in tax laws or
     rates.

     DEFERRED FINANCING COSTS

     Deferred financing costs are stated at cost as a component of other assets
     and amortized over the life of the related debt using the effective
     interest method. Amortization of deferred financing costs is included in
     interest expense.


                                                                             (7)

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

</TABLE>


          Inventories valued under the last-in, first-out (LIFO) cost method
          comprised approximately 62.5% of the July 5, 1997 totals and 60.5%
          of the 1996 totals.


     8.   LONG-TERM DEBT AND NOTES PAYABLE TO BANKS

          In November 1996, the Company entered into a Bank Credit Agreement
          (the "Agreement") that provides for secured borrowings from a
          syndicate of lenders consisting of (i) a five and one-half year
          revolving credit facility providing for up to $30 million in revolving
          loans, $5.0 million of which may be used for letters of credit (the
          "Revolving Credit Facility") and (ii) a term loan facility providing
          for $45.0 million in term loans, consisting of a five and one-half
          year Tranche A Term Loan of $20.0 million and a seven and one-half
          year Tranche B Term Loan for $25.0 million (collectively, the Term
          Loans).

          On June 30, 1997, the Company borrowed $20.0 million under the
          Revolving Credit Facility to finance the Alfa Acquisition (see
          Note 4).

          In connection with the Merger, the Company issued $115.0 million of
          Senior Subordinated Notes due in 2006 (the "Notes"). The Notes are
          unsecured obligations of the Company. The Notes bear interest at a
          rate of 10.625% per annum, which is payable semi-annually on each June
          30 and December 31, commencing on June 30, 1997.

          Under the terms of both the Agreement and the Note indenture, AMTROL
          is required to comply with certain financial covenants and
          restrictions with which AMTROL was in compliance at July 5, 1997.


                                                                             (8)

     9.   PROVISION FOR INCOME TAXES

          The effective income tax rates used in the interim financial
          statements are estimates of the full year's rates. The difference for
          1997 between a provision computed using the respective statutory U.S.
          federal income tax rate and the provision for income taxes in the
          accompanying consolidated financial statements is primarily the result
          of goodwill amortization and certain foreign operating losses for
          which there is no tax benefit.


     10.  SALE OF ASSETS

          In May 1997, the Company sold all of the assets, subject to
          substantially all liabilities, of its American Granby Inc. subsidiary.
          Accordingly, the results of American Granby are included in the
          accompanying consolidated statements of operations for the first five
          months of 1997 as compared to the entire six month period in 1996. Net
          sales and operating income included in the accompanying consolidated
          statements are as follows:

          In May 1997, the Company sold its Peru, Indiana production facility
          and the related pump business. AMTROL transferred certain production
          activities performed in Peru to the Company's West Warwick, RI
          facility. The Company believes that the operational efficiencies
          gained through production consolidation will offset lost contribution
          from the pump business.

          The Company utilized the net proceeds of the sales of approximately
          $6.0 million to fund seasonal working capital demands as well as the
          Alfa Acquisition.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION




OVERVIEW

The following discussion should be read in conjunction with the consolidated
Financial Statements and Notes thereto appearing elsewhere in this report. This
report contains forward-looking statements within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934. Such statements involve risks and uncertainties that could cause actual
results to differ materially from those set forth in such forward-looking
statements. Among other things, expectations for upcoming periods are based on
assumptions which management believes to be reasonable at this time, including
assumptions concerning the volume and product mix of sales. Moreover, there can
be no assurances when initiatives undertaken by the Company to improve plant
productivity will be successful. Other significant potential risks and
uncertainties include the following: risks associated with indebtedness;
uncertainties of acquisition strategy including the successful integration of
the Alfa Acquisition; high level of competition in the Company's markets;
importance and costs of product innovation; risks associated with international
operations; product liability exposure and the risk of adverse effects of
economic and regulatory conditions on sales; and risks associated with
environmental matters.

The consolidated balance sheet of the Company at July 5, 1997 reflects
allocation of the purchase price to the assets acquired in the Merger and
reflects the balances of Alfa as of such date. Operating results subsequent to
the Merger are comparable to prior periods, with the exception of depreciation,
interest expense and amortization of intangible assets and the sale of the
Company's American Granby accessory business.

                                                                            (10)

</TABLE>

Company results for the quarter were impacted by the divestiture of its American
Granby accessory business in May 1997 (see Note 10) as June did not include
sales and income from the accessory business which were included in the
comparable period in 1996. In addition, in the chemical container business,
competitive pricing actions as well as the movement of chemical container
customers towards long-term single source contracts, have adversely affected
margins. However, the Company believes it has successfully maintained market
volume and position. Sales of the Company's water systems products in June were
not as strong as anticipated due to ongoing slow industry-wide market
conditions. As a result, the Company increased its marketing and promotion costs
to maintain its market leadership in its water systems market. The plumbing and
heating sector continues to show strength.

                                                                            (11)

RESULTS OF OPERATIONS (con't)
------------------------------

Due primarily to the divestiture of the Company's American Granby accessory
business in May 1997, which resulted in no accessory sales being included for
June 1997 as compared to $2.6 million for June 1996, net sales for the second
quarter of 1997 decreased by $4.7 million, or 9.7%, from the same period in
1996, which was the highest sales quarter in Company history.

In addition, while sales in the first two months of the 1997 second quarter were
consistent with the Company's expectations, sales in June were not as strong as
anticipated due to slow industry-wide market conditions in the water systems
market. This resulted in a shortfall of $1.1 million in sales when compared to
the strong performance in the second quarter of 1996. Also, despite stable unit
volumes, the Company experienced a $ 0.8 million decrease in sales of domestic
disposable containers from the comparable period in 1996 due to the
aforementioned competitive pricing actions.

Net sales for the six months ended July 5, 1997 decreased by $0.9 million or 1.0
% when compared to 1996 due primarily to the divestiture of the Company's
accessory business. Excluding the impact of the divestiture of American Granby,
sales for the six months ended July 5, 1997 increased $1.7 million or 2% when
compared to 1996, primarily due to increased sales of the Company's plumbing and
heating products.

The gross profit in the second quarter decreased by $2.5 million or 18.5% from
the previous year and the margin percentage decreased to 25.2% of net sales in
1997 from 28.0% in 1996. The gross profit percentage was unfavorably affected by
unanticipated high costs associated with the new Singapore production facility.
In addition, during 1997, the Company experienced higher product returns than
normal, due to a manufacturing process problem which has since been corrected.
The Company believes these incremental product returns will be resolved by the
end of 1997.

As previously discussed, pricing and promotion costs due to competitive market
conditions in the Company's water systems and chemical container markets
decreased gross profit. Increased raw material costs also adversely affected the
gross margin as well as incremental depreciation expenses of $0.3 million for
the six months ended July 5, 1997 from the comparable period in 1996.

For the six months ended July 5, 1997, gross profit decreased by $1.5 million or
6.2% as compared to the same period in 1996, and the gross profit percentage
decreased to 25.6% of net sales in 1997 from 27.0% in 1996.

The Company's acquisition of Alfa in Portugal provides it with a low-cost
international manufacturing facility. With the continuing operating losses at
its Singapore production facility, the Alfa Acquisition provides the Company
with the flexibility to reevaluate its international manufacturing strategy. The
Company expects to complete this review in the third quarter.

                                                                            (12)

RESULTS OF OPERATIONS (con't)
-----------------------------


Selling, General and Administrative expenses decreased $1.3 million or 16.9% to
$6.3 million in the second quarter of 1997, and as a percentage of net sales was
14.4% in 1997 and 15.7% in 1996. Expenses decreased primarily due to reductions
in corporate overhead and restructuring of the Company's general and
administrative staff, as part of the Company's new business strategy. For the
first six months of 1997, Selling, General and Administrative Expenses decreased
by $2.6 million to $12.7 million, or 14.3% of net sales in 1997 from $15.3
million or 17.1% of net sales in 1996.

Amortization expense of $0.9 million for the second quarter and $1.9 million for
the first six months of 1997 results from amortization of goodwill recorded as
part of purchase accounting in connection with the Merger.

Earnings before interest, taxes, depreciation and amortization (EBITDA) in the
second quarter of 1997 decreased to $6.1 million from $7.2 million in the
comparable period of 1996. For the six months, EBITDA increased by $1.5 million
to $13.1 million from $11.6 million in 1996. Excluding the impact of the
divestiture of the accessory business, EBITDA would have increased by $1.7
million or 15% for the six month period and would have decreased by $0.8 million
for the quarter.

Interest expense of $4.4 million for the second quarter and $8.9 million for the
six month period reflects the Company's higher levels of debt related to the
financing of the Merger.

Net (loss) for the second quarter was $0.9 million, a decrease in income of $4.6
million reflecting the $2.1 million decrease in operating income together with
the increase in interest expense.

Due to the timing of the Acquisition, the results of operation of Alfa will be
included with the consolidated results of AMTROL commencing with the third
quarter.

INFLATION

In recent years, inflation has been modest and has not had a material impact
upon the results of the Company's operations.

LIQUIDITY AND CAPITAL RESOURCES

Working Capital at July 5, 1997 was $33.5 million and the ratio of current
assets to current liabilities was 1.98 to 1.0. This compares with working
capital of $35.2 million and a current ratio of 2.5 to 1.0 at December 31, 1996.

The Company experienced an increase in its Accounts Receivable balance due to
the increased level of sales activity, reflecting seasonal demand, when compared
to the fourth quarter of 1996. Inventories increased from year end due to
seasonality and increased inventory service levels to provide improved customer
service.


                                                                            (13)

LIQUIDITY AND CAPITAL RESOURCES (con't.)
-----------------------------------------

During the six months ended July 5, 1997, the Company used cash flows from
operating activities of $ .7 million. During this same period, the Company
invested $3.3 million, net, in machinery and equipment and repaid debt of $.3
million. As a result of the foregoing, the Company's cash balance decreased by
$4.3 million.

The Company's total capital expenditures for 1997 are projected to be $7.0
million.

In connection with the Merger, AMTROL issued $115.0 million of Senior
Subordinated Notes due 2006 (the "Notes") issued under an Indenture dated as of
November 13, 1996. The Notes are unsecured obligations of AMTROL. The Notes bear
interest at a rate of 10.625% per annum and are payable semi-annually on each
June 30 and December 31 commencing on June 30, 1997. In addition, on or prior to
December 31, 1999, the Company may use the net cash proceeds of one or more
public equity offerings to redeem up to 35% of the aggregate principal amount of
the Notes originally issued at a redemption price of 110.625% of the principal
amount thereof plus accrued interest to the date of redemption. Upon a "Change
of Control" (as defined in the Indenture), each Note holder has the right to
require the Company to repurchase such holder's Notes at a purchase price of
101% of the principal amount plus accrued interest. The Indenture contains
affirmative and negative covenants and restrictions similar to those required
under the terms of the Bank Credit Agreement discussed below. As of July 5,
1997, AMTROL is in compliance with the various covenants of the Indenture.

The Company has a substantial amount of indebtedness. The Company intends to
fund its future working capital expenditures and debt service requirements
through cash flows generated from operations (including the results of
initiatives to significantly reduce operating expenses) and borrowings under the
revolving credit facility (the "Revolving Credit Facility") provided under the
Bank Credit Agreement. Upon consummation of the Merger on November 13, 1996, the
Company became party to the Bank Credit Agreement. The Bank Credit Agreement
provides for $45.0 million of senior term loans (the "Term Loans") and a $30.0
million Revolving Credit Facility. A portion ($20.0 million) of the Term Loans
(the "Tranche A Term Loans") will mature five and one-half years after the
effective date of the Merger, with quarterly amortization payments during the
term of such loans. The remainder ($25.0 million) of the Term Loans (the
"Tranche B Term Loans") will mature seven and one-half years after the effective
date of the Merger, with nominal quarterly amortization prior to the maturity of
the Tranche A Term Loans and with the remaining amounts amortizing on a
quarterly basis thereafter. The Revolving Credit Facility includes a sublimit
providing for up to $20.0 million of availability on a revolving credit basis to
finance permitted acquisitions. On June 30, 1997, the Company borrowed $20
million, representing the entire acquisition sublimit under the Revolving Credit
Facility, to fund the acquisition of Alfa. The commitments under the Revolving
Credit Facility and the acquisition sublimit will reduce by $5.0 million in the
fourth year and $10.0 million in the fifth year after the effective date of the
Merger, November 13, 1996. The Revolving Credit Facility will mature five and
one-half years after the effective date of the Merger. The Bank Credit Facility
is secured by substantially all assets of the Company and its subsidiaries.


                                                                            (14)

LIQUIDITY AND CAPITAL RESOURCES (con't.)
-----------------------------------------

Management believes that cash generated from operations, together with
borrowings available under the Revolving Credit Facility, will be sufficient to
meet the Company's working capital and capital expenditure needs in the
foreseeable future. The Company may consider other options available to it in
connection with funding future working capital and capital expenditure needs,
including the issuance of additional debt and equity securities.

The Company has sold all of the assets, subject to substantially all
liabilities, of its American Granby Inc. subsidiary. In May 1997, the Company
sold its Peru, Indiana production facility and the related pump business. AMTROL
transferred certain production activities performed in Peru into the Company's
West Warwick, RI facility. The Company believes that the operational
efficiencies gained through production consolidation will offset lost
contribution from the pump business. It expects to apply the net proceeds of the
sales, approximately $6.0 million, to fund seasonal working capital demands as
well as the acquisition of Alfa.
