            NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)



Note 1 - Significant Accounting Policies

Basis of Presentation

     The condensed consolidated financial statements include the accounts of the
company and its  wholly-owned  subsidiaries.  In the opinion of management,  the
financial  statements  include all  material  adjustments  necessary  for a fair
presentation of the Company's financial position, results of operations and cash
flows.  The results of this interim  period are not  necessarily  indicative  of
results for the entire year.

Inventories

     Inventories are valued at the lower of cost or market.  Cost of inventories
is determined principally by the last-in, first-out (LIFO) method.

Income Taxes

     Provisions for income tax in the amounts of $1,666,000 and $1,377,000  were
recorded for the three months ended June 30, 1998 and 1997, respectively.

Goodwill

     The  Company  amortizes  Goodwill  on the  straight  line  basis  over  the
estimated  period to be  benefitted.  The  acquisitions  of  National  Northeast
Corporation,  National Southeast Aluminum Corporation, and Heat Exchangers, Inc.
in 1995 resulted in goodwill of  $11,118,000  which is being  amortized  over 25
years. The acquisitions of Rowe Machinery and Automation,  Inc., and Omega Flex,
Inc. in 1996 resulted in goodwill of $7,729,000 which is being amortized over 25
years. The acquisition of Hill Engineering,  Inc. on January 31, 1997,  resulted
in  goodwill  of  $2,892,000  which  is  being  amortized  over  25  years.  The
acquisition  of RBI,  on April 29,  1998,  as more  fully  described  in Note 2,
resulted in goodwill of $1,781,000  which will be amortized  over 25 years.  The
Company  continually  evaluates the carrying value of goodwill.  Any impairments
would be recognized when the expected  future  operating cash flows derived from
such goodwill is less than their carrying value.

Reclassification

     Reclassifications  are made  periodically  to previously  issued  financial
statements to conform with the current year presentation.

Note 2 - Business Acquisitions

     On April 29, 1998,  the Company,  through a Canadian  subsidiary,  acquired
100% of the outstanding  common stock of Ruscio  Brothers  Refractory Ltd, (RBR)
and 988721 Ontario, Inc. (988721), both of Mississauga Ontario,  Canada. RBR and
988721  manufacture  and  distribute  commercial and  residential  copper-finned
boilers and water  heaters  under the name  Ruscio  Brothers  Industries,  (RBI)
primarily in Canada.  Copper-finned  boilers and water heaters are complimentary
to  the  Company's   other  hydronic   products  and  the  Company   expects  to
substantially  increase the distribution of RBI's products in the United States.
The purchase  price paid for the  acquired  stock was  approximately  $3,096,000
(U.S.) and included Goodwill of approximately $1,781,000 (U.S.).

Revolving Loan Agreement - The Company has a Revolving Loan Agreement and Letter
of Credit  Facility  (the  Agreement)  with a  commercial  bank.  The  Agreement
provides $50 million of unsecured  revolving credit in U.S. dollars,  $5 million
of unsecured  involving credit in Canadian  dollars,  and $10 million of standby
letter of credit  capacity.  Borrowings  under the Agreement  bear interest at a
floating rate based on the bank's prime rate less 1.75% or, at the discretion of
the  borrower,  LIBOR plus a quoted  market  factor.  The Agreement was recently
renewed on a one year basis extending through April 30, 1999. The Revolving Loan
Agreement contains  financial  covenants which require that the Company maintain
certain current  ratios,  working  capital  amounts,  capital bases and leverage
ratios.  This  Agreement  also contains  restrictions  regarding the creation of
indebtedness,  the  occurrence  of  mergers  or  consolidations  , the  sale  of
subsidiary stock and the payment of dividends in excess of 50% of net income.

Senior  Notes - On  April  5,  1996  the  Company  borrowed  $15,000,000  from a
commercial  insurance  company on an unsecured basis,  executing a Note Purchase
Agreement and the related Senior Notes, (The Notes).  The Notes matured and were
paid off on March 1, 1998. The notes bore interest at 5.53% per annum.

Other - Other bonds and notes payable  include  $670,000 in secured  obligations
assumed in connection with the purchase of Hill Engineering, Inc. on January 31,
1997.

Note 5 - Earnings Per Common Share

     Basic earnings per share were computed using the weighted average number of
common  shares  outstanding.   Common  stock  options  were  considered  in  the
computation of diluted earnings per share.

Note 6 - Shareholders Equity

     The Company  continued its program of selective "open market"  purchases of
its  common  stock in the second  quarter  of 1998.  6,400  common  shares  were
acquired in the three month period ended June 30, 1998, and are accounted for as
treasury stock

Item 2 - Management's Discussion and Analysis of Financial Condition and
Results of Operation

     Total  revenues in the Company's  HVAC segment during the second quarter of
1998 were reduced  relative to the second  quarter of 1997, by $732,000 or 1.4%.
HVAC sales were adversely effected by the relatively mild winter of 1997/1998 as
well as by changes in the Company's  traditional  deferred billing program which
resulted in the postponement of certain shipments, and related billings from the
first and second quarters to the third quarter of 1998. Gross profit margins for
the HVAC segment decreased slightly,  from 26.7% to 25.6%. Margins were effected
by  the  planned  reduction  in  the  Company's  Orangeville,   Ontario,  Canada
manufacturing  operations,  the cost of which  was  reserved  for in the  second
quarter of 1998.  Operating income for this segment was accordingly reduced from
$2,312,000 in the second  quarter of 1997 to $1,556,000 in the second quarter of
1998.

     Total   Revenues  in  the  Company's   Metal   Products   segment  were  up
significantly  during the second quarter of 1998, relative to the second quarter
of 1997, ($23,856,000 versus $20,268,000) principally as a result of substantial
growth  in the  segment's  National  Northeast,  OmegaFlex  and  Formtek  units.
National  Northeast  has  continued  to expand  its  capabilities  as a high end
manufacturer  of thermal  heat sinks.  OmegaFlex's  Trac-Pipe(TM)  flexible  gas
piping  product  has been an  unqualified  success  with  demand for the product
substantially exceeding expectations.  The Company believes that the substantial
capital investments made by OmegaFlex in 1996 and 1997 in Trac-Pipe(TM)  product
development and market development have resulted in superior technology, as well
as "low cost-producer" status, in this emerging HVAC niche. As a result of these
factors, gross profit margins improved  significantly,  from 23.6% to 31.0%, and
operating income increased from $1,224,000 to $2,962,000.

     The Company's  computer systems segment reported slightly reduced revenues,
and gross profit margins and, as a result, slightly reduced operating income.

     For the  Company  as a whole,  Selling,  General  and  Administrative,  and
Engineering  costs,  taken together as a percentage of Total  Revenues,  were up
very slightly from 21.1% to 21.4%.

     Operating income for the second quarter of 1998 for the Company as a whole,
increased  by  $776,000  or  18.6%  reflecting  the net  effect  of the  factors
mentioned above.

     The Company's  total debt (long-term debt plus current portion of long-term
debt) increased by $8,158,000 during the quarter ended June 30, 1998 principally
as a result of seasonal growth in inventories as well as the acquisition of RBI,
as more  fully  described  in  Note 2 to the  Condensed  Consolidated  Financial
Statements.  Management  regards the  Company's  current  capital  structure and
banking  relationships as fully adequate to meet  foreseeable  future needs. The
Company has not paid dividends on its common stock since 1979.

         consummation  of the  transactions  contemplated by this Agreement will
         not  entitle  any  Employee  to pay in lieu of notice  of  termination,
         termination  pay or severance pay,  unemployment  compensation,  or any
         other payment.  The Businesses have always been, and are, carried on in

         a copy of which has been provided to the Buyer. There have not been any
         accidents, issues, or incidents involving the Business or the Companies
         necessitating or potentially leading to any Workers' Compensation claim

     commitment,  whether  legally binding or not, to create any additional Plan
     or to change any  existing  Plan that would  affect any  Employees or their

         There are no outstanding complaints,  actions, suits, or claims pending
         or threatened by any Person  relating to any of the Plans.  None of the
         Companies or any  administrator  or fiduciary of any Plan, or any agent
         or employee of any of the foregoing has taken any action,  or failed to
         take any action,  that would  subject  either of the  Companies  or any
         other Person to any liability for any excess Tax or for a breach of any
         statutory or fiduciary  duty with respect to or in connection  with any
         Plan.  No  notification  is  required  to be  given  to any  regulatory
         authority having jurisdiction over any of the Plans with respect to the
         consummation  of the  transactions  contemplated  by this  Agreement in
         relation to such Plans.

         its terms and with the  requirements of all applicable Laws and each of
         the Plans has been duly  registered  where  required by, and is in good
         standing  under,  such  Laws.  None of the  Plans  is a  multi-employer

         legislation.

         Companies'  property  used by or for the  Businesses or from a facility
         owned or operated by any other Person, but with respect to which either
         of the  Companies  in  respect  of the  Businesses  is  alleged to have
         liability.  All wastes and other materials and substances  disposed of,

         Environmental  Laws.  Schedule  3.12.1  identifies all of the locations
         where Hazardous Material used in whole or in part by Sellers in respect
         of or in the conduct of the Businesses or resulting from the Businesses
         has been or is being  stored or disposed of. No action of either of the
         Companies  in  respect of the  Businesses  will give rise to any claim,
         demand, or action seeking the clean-up of any site,  location,  body of
         water,  surface,  or  subsurface,  wherever  located.  The Sellers have

         year has terminated or has advised either Company that such customer is

         its business  relationship  with either Business or, to the best of the
         Companies'  knowledge,  is planning to reduce its purchases of services
         in the next twelve-month period. All of the Contracts are in full force
         and effect, unamended, are valid, binding and enforceable and no breach
         or default exists in respect  thereof on the part of any of the parties
         thereto nor has any event  occurred  which with the giving of notice or
         the  passage  of  time,  or both,  could  constitute  such a breach  or
         default.  Schedule 3.13.1  identifies every Contract which requires the
         consent of the other party thereto  ("Consent")  to a change in control
         of either of the Companies,  and whether such Consent is to be given in
         writing and/or prior to such change in control.

         Employees of the  Businesses  and true and complete  copies of the most
         recent inspection reports, if any, received from insurance underwriters

         relating to or affecting the  Businesses,  and, to the best of Sellers'

          complete  records for all taxation years which remain subject to audit
     by action of statute or waiver for all periods or portions  thereof through
     and  including  the  Effective  Date.  To the extent that such  records are
     currently  maintained in both a hard copy and an  electronic  media format,
     the Parties  agree to cause both such types of records  that pertain to the
     income or operations of the companies prior to the close of business on the
     Effective  Date to be  retained by  Companies  and not to be  destroyed  or
     altered without prior written approval of Sellers or Buyer, as the case may
     be. The  Parties  agree to cause the  Companies  to enter into such  record

         relating to a transaction that occurred prior to the Effective Date and
         which was not included in the Net Worth  Calculation,  then Buyer shall
         promptly  pay or cause the  Companies to pay the amount of such Account
         Receivable to the Sellers or as the Sellers shall jointly  direct.  Any
         such payment shall be deemed to have  increased  the Purchase  Price by
         the  amount  of such  payment.  Any  Account  Receivable  which was not
         included in the Net Worth Calculation is hereby assigned to Sellers for
         no additional consideration.

6.7      Temporary Occupancy.  Notwithstanding the execution and delivery of the
         Lease,  as described in section 7.3 below,  the parties  agree that the

         the Rainbow  Assets  shall be permitted to continue to operate from the
         Property for a period of up to sixty (60) days from the Closing Date so
         long as all such operations and activities are not in breach of and are
         subject  to the terms and  conditions  of the Lease as if such  company
         were also a tenant,  and with the understanding and limitation that its
         employees  and agents  shall only be  permitted  access to the Property
         during the regular  business hours of RBR and RES, or upon prior notice
         and the  reasonable  agreement of RBR and RES. The Sellers hereby agree
         to  indemnify  RBR and RES  against  and hold  them  harmless  from all
         losses,  damages,  expenses or liabilities  of whatever  nature or kind
         caused directly or indirectly by such occupation by such company or the
         removal of its assets from the Property.

<PAGE>


         or warranty of Sellers contained in this Agreement or in any 
         certificate or other document furnished by Seller;

     Buyer or  Companies on a solicitor  and client  basis) which may be made or
     brought or levied  against  Buyer or  Companies or which either of them may
     suffer or incur as a result of, in respect  of, or arising out of a Breach;
     and

         to the date of payment.

9.3      Notification

         Buyer  shall  notify  Sellers  promptly  after it becomes  aware of any
         matters for which they may be liable  under  section 9.2 and subject to
         the  provisions  of section 9.4 hereof  Sellers shall have the right to

         compromise or settle such Claim without the participation or consent of
         Sellers.

         During  the  period  that  Sellers  are  entitled  to defend  any Claim
         pursuant  to section  9.4,  Buyer shall (but at the expense of Sellers)
         co-operate  with Sellers in  connection  with the defence of such Claim
