                          INDEPENDENT AUDITORS' REPORT





Board of Directors and Stockholder
Baker Distributing Company

     We have audited the accompanying consolidated balance sheet of Baker
Distributing Company (formerly known as Baker Bros., Inc.) and subsidiary (the
"Company"), a wholly-owned subsidiary of Trek Corporation, as of September 30,
1996, and the related consolidated statements of income and retained earnings
and cash flows for the year then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

     In our opinion, such financial statements present fairly, in all material
respects, the financial position of Baker Distributing Company and subsidiary as
of September 30, 1996 and the results of their operations and their cash flows
for the year then ended in conformity with generally accepted accounting
principles.

                    BAKER DISTRIBUTING COMPANY AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 (In thousands)


1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation - The consolidated financial statements have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission and include the accounts of Baker Distributing Company (the
"Company") and its wholly-owned subsidiary, Booth Refrigeration Supply Co., Inc.
("Booth"). All material intercompany profits, transactions and balances have
been eliminated. The Company is a wholly-owned subsidiary of Trek Corporation
(the "Parent").

     Interim Financial Information - The unaudited consolidated balance sheet as
of June 30, 1997 and the unaudited consolidated statements of income and
retained earnings and cash flows for the nine months ended June 30, 1997 and
1996 include, in the opinion of management, all adjustments necessary to present
fairly the Company's consolidated financial position, results of operations and
cash flows. The results for the nine months ended June 30, 1997 are not
necessarily indicative of the results for the year ending September 30, 1997.
The sale of the Company's products is seasonal with revenues generally
increasing during the months of May through August.

     Cash - Cash includes cash on hand and on deposit at various financial
institutions.

     Depreciation and Amortization - Property, plant and equipment are stated at
cost. Depreciation and amortization are computed by the straight-line method
over the estimated useful lives of the assets. When items of property are
retired or otherwise disposed of, the cost of the assets and the accumulated
depreciation are removed from the accounts. Any resulting gains or losses are
taken into income.

     Discount amortization - Discounts on long term debt are being amortized on
a straight-line basis over the life of the related debt.

     Income Taxes - Deferred income taxes are calculated in accordance with the
method described by the Financial Accounting Standards Board under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes".
Accordingly, deferred income taxes are recognized for items of income and loss
recognized in different periods for financial and income tax reporting purposes
and on differences between book and tax bases of net assets acquired in purchase
transactions using presently enacted rates.

     Use of Estimates - The preparation of consolidated 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.

     Fair Value of Financial Instruments - The Company believes the carrying
amount of its financial instruments (cash, accounts receivable, employee
receivables, accounts payable, deferred compensation under stock appreciation
rights plan and long-term debt) is a reasonable estimate of the fair value of
these instruments.

     Future Accounting Pronouncements - In March 1995, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards No. 121,
"Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to be
Disposed of" ("SFAS 121"). SFAS 121, which is effective for years beginning
after December 15, 1995, establishes accounting standards for the impairment of
long-lived assets, certain identifiable intangibles, and goodwill related to
those assets to be held and used for long-lived assets and certain identifiable
intangibles to be disposed of. Impairment is assessed by comparing the book
value of such assets to the estimated undiscounted future operating cash flows
expected to result from the use of the asset and its final disposition. If the
sum of the expected future cash flow is less than the carrying amount of the
asset, an impairment loss is recognized based on the fair value of the asset.
Effective October 1, 1996, the Company 

                                       10

adopted SFAS 121. The adoption of SFAS 121 did not have a material effect on the
Company's consolidated financial position or results of operations.

2.  BUSINESS

     Substantially all of the Company's revenue is derived from the wholesale
distribution of air conditioning, refrigeration and heating equipment,
appliances, parts and supplies. The Company's operations encompass the states of
Alabama, Florida, Georgia, Louisiana, North Carolina, South Carolina and
Virginia.

3.  INVENTORIES

     All inventories are valued at the lower of cost determined by the last-in,
first-out (LIFO) method or market. The LIFO method results in a more appropriate
matching of current costs with current revenues. Under the LIFO method of
inventory valuation, inventories were reduced by approximately $4,018 at
September 30, 1996.

     If the first-in, first-out (FIFO) method of inventory valuation had been
used, income before income taxes would have been increased by approximately $892
for the year ended September 30, 1996.

4.  LONG-TERM DEBT

     Long-term debt at September 30, 1996 consists of:

        Mortgage note (7-1/4% at September 30, 1996) due in

     The Company leases certain facilities and equipment under noncancellable
long-term operating leases which expire at various dates through 2014. Future
minimum lease commitments as of September 30, 1996 were as follows:

                                  REAL ESTATE  EQUIPMENT      TOTAL

                                    =========  =========   =========

Some leases require the Company to pay property taxes, insurance and normal
maintenance and repairs and have renewal options. Total rental expense was
approximately $4,313 for the year ended September 30, 1996.

6.  INCOME TAXES

     The provision for income taxes has been computed as if the Company filed
tax returns separate from the Parent. The difference between the total taxes
reported for the Company and all other subsidiaries of the Parent and the
consolidated expense is reported as part of the Parent's tax expense or credit.
The Parent therefore receives the benefit of or charge for any difference
between the consolidated tax provision and separate return provisions. The
provision for income taxes for the year ended September 30, 1996 includes the
following:

           Current payable                        $  2,620
           Deferred                                     37
                                                  --------
           Provision for income tax               $  2,657
                                                  ========

     Reconciliation from the statutory U.S. Federal income tax rate to the
Company's effective rate is as follows:

           Statutory tax rate                        35.0%
           Effect of graduated rates                 (1.0)
           State income taxes, net of Federal
             income tax benefit                       3.9
           Other, net                                  .9
                                                    -----
           Effective tax rate                        38.8%
                                                    ======

     The Company's temporary differences are principally related to
depreciation, timing of deductibility of other accruals and recognition of other
gains and their related tax effects. Deferred tax assets and liabilities at
September 30, 1996 are summarized below:

           Deferred tax assets                     $ 1,223
           Deferred tax liabilities                   (939)

     The Company, through its acquisition of Booth, can utilize certain tax
attributes such as a net operating loss carryforward ("NOL") for both regular
and alternative minimum tax purposes. The amount of the NOL for regular tax
purposes is $949. The utilization of such losses is limited on an annual basis
subject to certain limitations in the Internal Revenue Code and will expire in
varying amounts ending in the year 2010.

7.  PROFIT-SHARING AND RETIREMENT PLANS

     The Company has a trusteed, non-contributory profit sharing and retirement
plan covering substantially all employees of the Company. During the fiscal year
ended September 30, 1996, Booth's plan was merged into the Company's plan. The
annual contribution to the plan is determined at the discretion of the Board of
Directors and amounted to $910 for the year ended September 30, 1996.

8.  RELATED PARTY TRANSACTIONS

     The Parent provided the Company short-term advances with interest at the
prime rate during the year ended September 30, 1996. There were no outstanding
borrowings at September 30, 1996. Interest incurred on these short-term
borrowings was $218 in 1996.

     The Company provides long-term and short-term advances to the Parent. The
long-term advances are non-interest bearing and totaled $2,185 at September 30,

Outstanding borrowings under the notes were $37,700 at September 30, 1996.

     The Company incurred costs for the year ended September 30, 1996 of $1,300
for management services provided by the Parent and costs of $40 as a usage
charge for the Company's computer system, which was provided by the Parent.

     The Company also guarantees a credit agreement for the Parent. Amounts
available under the agreement are adjusted periodically according to seasonal
requirements and range from $57,000 to $84,000 for operating capital, letters of
credit and bankers acceptance financing. Additionally, $165,000 may be used to
enter into foreign exchange contracts. Outstanding borrowings were $28,800 at
September 30, 1996. In addition, there were $10,790 of letters of credit and
non-discounted bankers acceptances outstanding at September 30, 1996 and the

     The Company was allocated costs of $416 for the year ended September 30,
1996 for general business insurance and workmen's compensation insurance that
was obtained by the Parent for the benefit of the Company.

     The Company leases one store from the profit sharing and retirement plan as
of September 30, 1996. Rental expense to the plan was approximately $29 for the
year ended September 30, 1996.

9.  DEFERRED COMPENSATION UNDER APPRECIATION RIGHTS PLAN

     The Parent has a deferred compensation plan under which common stock
appreciation rights may be granted. Holders of the stock appreciation rights are
entitled to receive cash in an amount equal to the increase in book value per
share over the initial value. The charge to operations under the stock
appreciation rights plan was approximately $430 for the year ended September 30,
1996.

10. SUBSEQUENT EVENTS

     Effective June 30, 1997, Booth, the Company's wholly-owned subsidiary, was

     On September 30, 1997, the Parent completed a transaction pursuant to a
Stock Purchase Agreement (the "Agreement") with Watsco, Inc. ("Watsco") whereby

                          WATSCO, INC. AND SUBSIDIARIES
               NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS


(1) The Unaudited Pro Forma Condensed Consolidated Financial Statements give
    effect to the purchase by Watsco, Inc. ("Watsco") of all the issued and
    outstanding capital stock of Baker Distributing Company ("Baker"). The pro
    forma information is based on the historical financial statements of Watsco
    and Baker. The acquisition will be accounted for under the purchase method
    of accounting.

    The Unaudited Pro Forma Condensed Consolidated Financial Statements may not
    necessarily be indicative of the results that would actually have been
    obtained had the acquisition of Baker occurred on the dates indicated or
    which may be obtained in the future. In the opinion of Watsco's management,
    all adjustments necessary to present fairly such Unaudited Pro Forma
    Condensed Consolidated Financial Statements have been included. The pro
    forma condensed consolidated financial statements should be read in
    conjunction with the historical financial statements and related notes of
    Watsco and Baker.

(2) The estimated purchase price for Baker is $65.3 million, including estimated
    acquisition expenses. Goodwill, representing the excess cost over the net
    assets acquired, will be amortized over a 40 year period. A reconciliation
    of the net assets of Baker to be acquired to the total estimated purchase
    price is as follows:

    Fair value of net assets                             $31,742
    Adjustment of inventory to FIFO cost basis             4,393
    Assets not purchased -
         Due from parent                                  (3,545)
         Employee receivables                               (584)
    Liabilities not assumed -
         Federal and state income tax liability              673
         Deferred compensation under stock
           appreciation rights plan, net of
           related tax benefit                             1,288
    Excess of purchase price over net assets acquired     31,333
                                                      ----------
         Total                                           $65,300
                                                      ==========

(3) The inventories included in the historical financial statements of Baker are
    stated under the last-in, first-out method. Subsequent to the acquisition of
    Baker, such inventory amounts will be stated by Watsco based on the
    first-in, first-out (FIFO) method. These amounts represent adjustments to
    reflect inventories and cost of sales using the FIFO method as if Baker
    valued inventories under the FIFO method as of the beginning of each year
    presented in the accompanying pro forma condensed consolidated financial
    statements.

(4) Watsco intends to use borrowings under its current revolving credit
    agreement to fund the acquisition of Baker's capital stock.

(5) Represents pro forma income taxes at a blended statutory rate of 38.5%.

        deliver to Watsco and the Escrow Agent (i) (A) an audited, consolidated
        balance sheet of Baker prepared in accordance with GAAP (as modified by
        this Agreement) dated as of the Closing Date with an unqualified opinion
        of Trek's Accountant's thereon and (B) Trek's calculation of the Net
        Book Value of Baker as of such date certified by Trek's Chief Financial
        Officer as having been prepared in accordance with GAAP (as modified by
        this Agreement) taking into account the adjustments described in (d)(i)
        below (collectively (A) and (B) are referred to herein as the "CLOSING
        DATE FINANCIAL STATEMENTS "), and (ii) a written statement of the
        Intercompany Account Adjustments (as defined in (d) below) certified by
        Trek's Chief Financial Officer as having been prepared in accordance
        with this Agreement and GAAP (as modified by this Agreement) (the
        "INTERCOMPANY ADJUSTMENTS SCHEDULE").

               In connection with the foregoing, Watsco shall make employees of
        Baker reasonably available to assist Trek (without charge) and such
        employees shall be instructed by Watsco to reasonably cooperate with
        Trek. Watsco agrees that following the Closing and until the final
        resolution of the calculation of the Purchase Price, Watsco will not
        take any actions with respect to the accounting books, records, policies
        and procedures of Baker that are not consistent with GAAP (as modified
        by this Agreement), except as otherwise provided herein.

               During the ninety (90) days immediately following Watsco's
        receipt of the Closing Date Financial Statements and the Intercompany
        Adjustments Schedule, Watsco and Watsco's Accountants shall be entitled
        to review and audit the Closing Date Financial Statements and the
        Intercompany Adjustments Schedule and perform additional audit
        procedures and duplicative audit procedures in connection with such
        review, and review Trek's and Trek's Accountant's working papers
        relating to the Closing Date Financial Statements and the Intercompany
        Adjustments Schedule. The Closing Date Financial Statements and the
        Intercompany Adjustments Schedule shall become final and 

                                       7
<PAGE>



        binding upon the parties on the ninetieth (90th) day following delivery
        thereof to Watsco, unless Watsco gives written notice to Trek and the
        Escrow Agent of its disagreement with the Closing Date Financial
        Statements and/or the Intercompany Adjustments Schedule (a "NOTICE OF
        DISAGREEMENT") prior to such date. Any Notice of Disagreement shall
        specify in reasonable detail the nature of any disagreement so asserted
        and the amount Watsco believes to be owing to it by Trek or the Escrow
        Agent. Watsco may dispute the amount of any item reflected in or omitted
        from the Closing Date Financial Statements and the Intercompany
        Adjustments Schedule which, alone or together with similar items, is
        material in relation to such item, but only on the basis that such
        amount was not arrived at in accordance with GAAP and this Agreement. If
        a timely Notice of Disagreement is received by Trek with respect to the
        Closing Date Financial Statements and the Intercompany Adjustments
        Schedule, then the Closing Date Financial Statements and the
        Intercompany Adjustments Schedule (as revised in accordance with the
        provisions set forth below), shall become final and binding upon the
        parties on the earlier of: (1) the date the parties hereto resolve in
        writing any differences they have with respect to any matter specified
        in a Notice of Disagreement; or (2) the date any matters properly in
        dispute are finally resolved in writing by the Settlement Accountants
        (as defined below).

               During the thirty (30) days immediately following the delivery of
        any Notice of Disagreement, Trek and Watsco shall seek in good faith to
        resolve in writing any differences which they may have with respect to
        any matter specified in such Notice of Disagreement. At the end of such
        30-day period, either Trek or Watsco may submit to a nationally
        recognized firm of independent certified accountants (the "SETTLEMENT
        ACCOUNTANTS") for review and resolution any and all matters which remain
        in dispute and which were included in any Notice of Disagreement, and
        the Settlement Accountants shall be instructed to resolve all matters
        which remain in dispute and, after resolving such matters that are in
        dispute and taking into account all matters which are not in dispute,
        calculate the Net Book Value of Baker as of the Closing Date. The
        Settlement Accountants shall be instructed to use reasonable efforts to
        perform its services within 15 Business Days of submission of the
        disputes, and in any case, as soon as practicable after such submission.
        The Closing Date Financial Statements and the Intercompany Adjustments
        Schedule, with such adjustments as necessary to reflect the Settlement
        Accountants' resolution of the matters in dispute, shall become final
        and binding on Watsco and Trek on the date the Settlement Accountants
        deliver their written resolution to the parties, absent manifest error.
        The Settlement Accountants shall be Price Waterhouse, or if such firm is
        unable or unwilling to act, such other nationally recognized firm of
        independent certified accountants (who have not performed services for
        either of Trek, Watsco or their respective Affiliates within the last
        five (5) years) selected by mutual agreement of Trek and Watsco. If Trek
        and Watsco are unable to agree, they shall retain the American
        Arbitration Association to select the Settlement Accountants. The costs
        and expenses of the Settlement Accountants (and of the American
        Arbitration Association, if used) shall be borne 50% by Watsco and 50%
        by Trek.

               (d)     CERTAIN ADJUSTMENTS.

                       (i) In addition to adjustments set forth elsewhere in the
               Agreement, the following adjustment shall be taken into account
               in the preparation of the Closing Date Financial Statements,
               notwithstanding that the amount will not be determined until
               after the Closing Date: On September 30, 1997, the Board of
               Directors of Baker shall declare a dividend to its shareholder of
               record as of the close of business on September 29, 1997, payable
               at such time as the Closing Date Financial Statements have become
               final and binding on Trek and Watsco (as provided in (c) above),
               equal to the amount, if any, of the "Due from Trek" intercompany
               account after taking into account the effect of the Intercompany
               Account Adjustments. The amount of the dividend shall be offset
               against the "Due from Trek" intercompany account as of the
               Closing Date which shall be reduced to zero. If the "Due from
               Trek" intercompany account represents an amount owing by Baker to
               Trek as of the Closing Date, Watsco shall cause Baker to pay such
               amount to Trek after taking into account the effect of the
               Intercompany Account Adjustments.

                       (ii) The following adjustments constitute the
               "INTERCOMPANY ACCOUNT ADJUSTMENTS" and shall be taken into

                       debited to the "Due from Trek" intercompany account.

                              (B) Pursuant to Section 5.6, the outstanding

                       reclassified and credited to the "Due from Trek"
                       intercompany account.

                              (C) Pursuant to Section 5.6, the amounts payable
                       to Terry Kelly, Carole Poindexter, Vernon Stacey and Jack

                       reclassified and credited to the "Due from Trek"
                       intercompany account.

                              (D) The amount, if any, of "Prepaid Federal and
                       State Income Taxes" shall be reclassified and debited to

                       State Income Taxes" shall be reclassified and credited to
                       the "Due from Trek" intercompany account.

                              (F) The amount derived by multiplying 38% by the
                       sum of (B) and (C) above (such amount representing the
                       deferred tax asset of such

                       from Trek" intercompany account.

               (e)     ADJUSTMENT TO THE PURCHASE PRICE.

                       (i) In the event the Net Book Value of Baker as reflected
               on the Closing Date Financial Statements (as finally determined
               in accordance with (c) above but excluding the effects of the
               Intercompany Account Adjustments) equals or exceeds $28,750,000,
               then the Escrow Agent shall remit the full amount of the Escrow
               Payment and all earnings thereon to Trek, and Watsco shall pay
               (or cause Baker to pay) to Trek the net amount of the
               Intercompany Account Adjustments.

                       (ii) In the event the Net Book Value of Baker as
               reflected on the Closing Date Financial Statements (as finally
               determined in accordance with (c) above but excluding the effects
               of the Intercompany Account Adjustments) is less than the
               $28,750,000 (the amount by which it is less than $28,750,000 is
               referred to herein as the "SHORTFALL"), then:

                              (A) if the Shortfall is less than the Escrow
                       Payment, (1) the Escrow Agent shall remit the amount of
                       the Shortfall to Watsco (together with a pro rata portion
                       of the earnings thereon), (2) after taking into account
                       (1), the Escrow Agent shall remit the balance, if any, of

                       Baker to pay) to Trek the net amount of the Intercompany
                       Account Adjustments; or

                              (B) if the Shortfall is more than the Escrow
                       Payment, (1) the Escrow Agent shall remit to Watsco the

               Except for Liens identified on SCHEDULE 3.11(B)(1), Baker has a
        valid leasehold estate in the real properties leased by it free and
        clear of all Liens but subject to the Contract relating thereto, for the
        full term thereof. Except as disclosed on SCHEDULE 3.11(B)(1), each such
        Contract is a legal, valid and binding agreement of Baker enforceable
        against Baker and the lessor named therein in accordance with its terms
        and, to the Knowledge of Trek, Baker is not, and no other party thereto
        is, in default under such Contract and no event has occurred which,
        after notice or lapse of time or both, would constitute a default
        thereunder. Except as disclosed on SCHEDULE 3.11(B)(2), the acquisition
        of the Shares by Watsco will not affect Baker's leasehold estates in any
        Leased Facility or require notice to or consent of any party to that
        Contract related thereto (or would with the passage of time or the
        giving of notice) or give rise to any payments or increased rental or to
        any right of the lessor party thereto to terminate the lease or any
        renewal rights or other options related thereto. To the Knowledge of
        Trek, no notice of foreclosure by a lender to a lessor of any Leased
        Facility of a Lien against the underlying real property has been
        received by Trek or Baker.

               (c) DOCUMENTS. Trek has delivered to Watsco prior to the
        execution of this Agreement true and complete copies of all Contracts
        (including any amendments and renewal letters relating thereto and all
        recordings thereof) with respect to any Owned Facility and any Leased
        Facility. Trek has made available to Watsco prior to the execution of
        this Agreement true and complete copies of any title policies, title
        opinions, surveys, environmental inspection reports, soils reports,
        mechanical or physical inspection reports, certificate of occupancy,
        operational licenses and permits that Trek or Baker or any of their
        respective Affiliates or Representatives (as hereinafter defined) have
        in its or their possession with respect to any Owned Facility or any
        Leased Facility.

               (d) CONDITION OF IMPROVEMENTS. The improvements located on each
        Owned Facility and are in good condition and in good repair, ordinary
        wear and tear excepted, and, other than repairs or maintenance to be
        performed in the Ordinary Course of Business and the cost of which will
        not exceed $50,000 in the aggregate, there are no capital repairs or
        deferred maintenance to be performed. To the Knowledge of Trek, the
        improvements located on each Leased Facility are in good condition and
        in good repair, ordinary wear and tear excepted, and there are no
        capital repairs or deferred maintenance to be performed which could have
        a Material Adverse Effect. There are no condemnation proceedings pending
        or, to the Knowledge of Trek, threatened against any Owned Facility or
        any or improvements thereon. To the Knowledge of Trek, there are no

                                       20
<PAGE>



        condemnation proceedings pending or threatened against any Leased
        Facility or improvements thereon. To the Knowledge of Trek, all
        utilities and similar systems which are required for the operation of
        Baker's business at all Owned Facilities and all Leased Facilities are
        installed and operating and are sufficient to enable all real property
        to continue to be used and operated in the manner currently being used
        and operated by Baker. Except as disclosed on SCHEDULE 3.11(D), all
        facilities on all Owned Facilities and, to the Knowledge of Trek, on all
        Leased Facilities have received all approvals of Government Authorities
        (including Permits) required in connection with the ownership or
        operation thereof and have been operated or maintained in accordance
        with applicable Laws other than such approvals the failure to which have
        obtained could not reasonably be expected to have a Material Adverse
        Effect. Other than the Leased Facility in Roanoke, Virginia, no Owned
        Facility and, to the Knowledge of Trek, no Leased Facility is located
        within a special flood hazard area.

               (e) CURRENT USE. Except as disclosed on SCHEDULE 3.11(E), the
        current use of the Owned Facilities and the Leased Facilities by Baker
        does not violate any of the Contracts with respect to any such
        properties or, to the Knowledge of Trek, any other instrument or
        Contract affecting any such property. To the Knowledge of Trek, there is
        no violation of any covenant, condition, restriction, easement,
        agreement or order of any Governmental Authority having jurisdiction
        over any of Owned Facilities that adversely affects any such real
        property or the use or occupancy thereof. The use of all Owned
        Facilities is a permitted use under the zoning/land use Laws applicable
        to such real property. Each Owned Facility is in compliance with the
        applicable zoning/land use Laws. Since September 30, 1996, no damage or
        destruction has occurred with respect to any Owned Facility or any
        Leased Facility which, individually or in the aggregate, has had or
        resulted in, or could have or result in, a Material Adverse Effect.

               (f) OTHER REAL PROPERTY INVESTMENTS. Except for the Owned
        Facilities and the Leased Facilities (collectively, the "REAL
        PROPERTY"), Baker does not occupy any other real property. Baker does
        not have any outstanding options (other than customary renewal options)
        or rights of first refusal to purchase or lease any of the real
        property, or any portion thereof or interest therein; except as
        reflected on SCHEDULE 3.11(A) or SCHEDULE 3.11(B)(1). ISI does not own
        or lease any real property.

        SECTION 3.12 TANGIBLE PERSONAL PROPERTY.

good title to, or has valid leasehold interests in or valid rights under
Contracts involving in each case an aggregate annual payment of $50,000 or more,
to use, all the tangible personal property used in the conduct of Baker's
business. All such tangible personal property is free and clear of all Liens,
except as disclosed on SCHEDULE 3.12, and is in all material respects in good
condition, ordinary wear and tear excepted. ISI does not own any tangible
personal property.

        SECTION 3.13 INVENTORY.

        All the inventory of Baker consists of finished goods inventory of a
quality and quantity usable and salable in the Ordinary Course of Business,
except for obsolete items or items below

GAAP has been made on the books of Baker. Baker has good and marketable title 
to such inventory, free and clear of all Liens, except as disclosed on SCHEDULE 
3.13. Except as described on SCHEDULE 3.13, no such inventory is held under a

from BONA FIDE sales transactions in the Ordinary Course of Business; and (b)
are collectible in the Ordinary Course of Business in the aggregate recorded
amounts thereof, subject to annual write-off adjustments consistent with prior
practice. Each of Baker and ISI has good title to all of its accounts
receivable, free and clear of any Liens, except as disclosed on SCHEDULE 3.14.

        of ERISA) (a "MULTIEMPLOYER PLAN") and does not have any Liability
        (including "withdrawal liability as such term is defined in Section 4201

        of ERISA) that is a "multiemployer plan" (as such term is defined in

        Section 414 of the Code with any trade, business, or entity other than

        or ISI), Baker or ISI, except for notices or communications that have
        been complied with in all material respects.

               (d) To the Knowledge of Trek, neither this Agreement nor the

from such registration is available.

        Trek shall determine the total amount of Baker's contribution to the
        Baker Bros., Inc. Profit Sharing and Retirement Plan for the plan year
        ended September 30, 1997, and the amount of such contribution shall be
        accrued on the Closing Date Financial Statements. Watsco shall cause
        Baker to contribute to the Baker Bros., Inc. Profit Sharing Retirement
        Plan no later than January 15, 1998, an amount equal to the liability
        accrued on the Closing Date Financial Statements for the plan
        contribution for the plan year ended September 30, 1997, and shall cause
        the plan to treat such contribution as a contribution for such plan
        year.

        SECTION 5.5 WELFARE BENEFIT PLANS.

               (a) Effective as of the Closing and continuing through the second
        anniversary of the Closing Date, Watsco shall cause Baker to maintain,
        or cause to be maintained for the benefit of Baker employees and former
        employees (and their dependents) employee welfare benefit plans,
        policies, and arrangements (including, without limitation, health,
        hospitalization, dental, vision, drug prescription, accidental death and
        dismemberment, life insurance and disability benefits) on terms and
        conditions which, when taken as a whole, are substantially comparable or
        superior to those benefits provided to Baker employees and former
        employees (and their dependents) immediately prior to the Closing Date;
        PROVIDED, HOWEVER, Watsco shall not be obligated to maintain any
        specific employee benefit plan, policy, or arrangement to the extent so
        doing would be in violation of any applicable law. Watsco shall cause
        each of the employee welfare benefit plans, policies, and arrangements
        covering Baker employees to recognize for eligibility and vesting
        purposes all service of such employees counted for such purposes under
        the corresponding plans provided to such employees by Baker immediately
        prior to the Closing Date.

               (b) With respect to any "group health plan" within the meaning of
        Section 5000(b)(1) of the Code, Watsco shall cause such plan to give
        credit to the Baker employees or former employees (and their dependents)
        for amounts paid under the corresponding plans provided to such
        individuals by Baker immediately prior to the Closing Date toward any
        applicable deductibles, co-payments, and out-of-pocket limits for the
        current plan year as though such amounts had been paid in accordance
        with the terms and conditions of Watsco's welfare benefit plans.

               (c) Effective as of the day following the Closing Date, Watsco
        shall take (or cause to be taken) all action necessary to otherwise
        appropriate to have Baker adopt and become a participating employer in a
        cafeteria plan within the meaning of Section 125 of the Code maintained
        for the benefit of employees of Watsco and its Affiliates (the "WATSCO
        CAFETERIA PLAN"), and shall amend such plan, to the extent necessary, to
        assume and recognize for purposes of the Watsco Cafeteria Plan any
        before-tax salary deferral elections for the current plan year with
        respect to the payment of employee premium 

                                       35

        expenses for the current plan year made by any Baker employees under the
        cafeteria plan maintained by Baker or Trek immediately prior to the
        Closing Date.

        SECTION 5.6 SAR AND CERTAIN NOTES.

        On or before the Closing Date, Trek shall cause any and all obligations
of Baker and of ISI under the Appreciation Rights Plan of Trek and any and all
obligations of Baker under the promissory notes described on SCHEDULE 3.30 under
the heading "SAR Notes" (the "SAR Notes"), at Trek's option, either to be
transferred to and assumed by Trek or to be fully discharged, with all of the
following results (a) none of Watsco, Baker or ISI shall have any Liability
under or related to such plan, and (b) none of Watsco, Baker or ISI shall have
any Liability under or related to the SAR Notes, and (c) neither the
Appreciation Rights Plan of Trek nor the SAR Notes will be reflected on the
Closing Date Financial Statements (other than as a result of being included in
the Intercompany Adjustments Schedule).

        SECTION 5.7 INDEMNIFICATION.

        Watsco agrees that all rights to indemnification now existing in favor
of the employees, agents, directors or officers of Baker and ISI, that are in
their respective articles of incorporation or by-laws shall survive the Closing
and shall continue in full force and effect, as obligations of Baker and ISI,
for a period of not less than six years from the Closing Date. Watsco further
agrees, for a period of six years, not to amend the articles of incorporation,
by-laws or other constitutive documents of Baker or ISI to reduce the scope of
the directors' and officers' indemnification provided for therein; PROVIDED,
HOWEVER, that in the event any claim or claims are asserted or made within such
six-year period, all rights to indemnification with respect to any such claim or
claims.

        SECTION 5.8 PAYMENT OF BONUSES.

        Watsco shall cause Baker to pay, no later than December 15, 1997,
bonuses for the fiscal year ended September 30, 1997, to such employees and
former employees of Baker and in such amounts as Trek shall reasonably
designate; PROVIDED, HOWEVER, that the total amount of such bonuses shall not
exceed the total amount of bonuses accrued as Liabilities on the Closing Date
Financial Statements.


                                   ARTICLE VI
                                MUTUAL AGREEMENTS

        SECTION 6.1 CONFIDENTIALITY.

        (a) For purposes of this Agreement, the term "CONFIDENTIAL INFORMATION"
        means all information furnished or made available to Watsco and its
        Affiliates and Representatives by Trek and its Affiliates and
        Representatives concerning Baker or ISI including, without limitation,
        customer and vendor information, financial statements, sales, sales
        volume, marketing strategy, business or financial plans or projections,
        and information concerning the identity, employees, facilities,
        operations, or ownership of Baker or ISI. Confidential 

                                       36
<PAGE>



        Information may be oral or in written, electronic or other form.
        Notwithstanding the foregoing, information which is or becomes generally
        available to the public other than as a result of a disclosure by Watsco
        or its Affiliates or Representatives does not for purposes of the
        Agreement constitute "Confidential Information".

               (b) From the date hereof until the Closing Date or, if the
        Closing does not occur, until July 21, 2002, without the prior written
        consent of Trek, Watsco shall not:

                         (i) Disclose or divulge in any manner or to any Person
               any of the Confidential Information; PROVIDED, HOWEVER, that
               Confidential Information may be disclosed to Watsco's
               Representatives who have a need to know such Confidential
               Information in connection with the transactions and matters
               contemplated by this Agreement (it being understood that
               Purchaser shall advise such Representatives of the existence of
               this Agreement and obtain their agreement to be bound by the
               terms hereof and shall not disclose the Confidential Information
               to any other person); or

                       (ii) copy or use Confidential Information for any purpose
               other than for purposes contemplated by this Agreement.

               Unless the Closing occurs (in which case, Trek shall no longer
        own any Confidential Information and all Confidential Information shall
        be the property of Baker), all Confidential Information shall remain the
        property of Baker or Trek, as the case may be.

               Until the Closing or, if the Closing does not occur, until July
        21, 2002, Watsco shall keep a record in reasonable detail of the
        Confidential Information and of the location of all such Confidential
        Information. As soon as possible upon the written request of Baker or
        Trek or following the termination of this Agreement by Watsco or Trek,
        Watsco shall (and shall cause its Affiliates and Representatives to)
        return to Baker or Trek, as the case may be, all tangible Confidential
        Information and will destroy (or, at Watsco's option, return to Baker or
        Trek) all Confidential Information prepared by Watsco or any of its
        Affiliates or Representatives. Such destruction (or return) will be
        confirmed in writing to Baker and Trek. Any Confidential Information not
        so destroyed (or returned) shall remain subject to this Agreement.

               If, prior to Closing or, if the Closing does not occur, prior to
        July 22, 2002, Watsco or its Affiliates or Representatives are requested
        or become legally compelled (by oral questions, interrogatories, request
        for information or documents subpoena, civil investigative demand or
        similar process), in the written opinion of Watsco's legal counsel, to
        disclose any Confidential Information, Watsco shall provide Baker and
        Trek with prompt notice of such request or requirement and the documents
        requested or required and cooperate with Baker and Trek so that Baker
        and Trek may seek a protective order or other appropriate remedy and/or
        waive compliance with the provisions of this Agreement and consult with
        Baker and Trek as to the advisability of taking legally available steps
        to resist or narrow such request. In the event that such protective
        order or other remedy is not obtained or Baker or Trek waives compliance
        with the provisions of 

                                       37
<PAGE>



        this Agreement, Watsco shall furnish only that Confidential Information
        which is legally required and shall, prior to such disclosure, consult
        with Baker and Trek as to the nature and wording thereof. Watsco will
        also, at Trek's direction, exercise reasonable efforts to obtain
        assurance that confidential treatment will be accorded the Confidential
        Information so disclosed.

               If Watsco or its Affiliates or Representatives shall breach or
        threaten to breach any of the provisions of this Section 6.1, Baker and
        Trek shall each immediately be entitled to injunctive relief without
        having to prove actual damages. It is specifically agreed that Baker or
        Trek may incur incalculable and irreparable damage from any such breach,
        and that neither Baker nor Trek would have adequate remedy at law and
        would be entitled to injunctive relief for any such actual or threatened
        breach. Nothing herein contained shall be construed as prohibiting Baker
        or Trek from pursuing any other remedies available to either on account
        of any breach or threatened breach of the provisions of this Section 6.1
        by Watsco or its Affiliates or Representatives, including recovery of
        money damages, and Watsco shall indemnify Baker and Trek and hold each
        harmless from and against any loss, damage, liability and expense,
        including attorney's fees, incurred by either Baker or Trek arising out
        of or relating to the breach of this Section 6.1 by Watsco or its
        Affiliates or Representatives or disclosure of Confidential Information
        by Watsco's Representatives unauthorized by Baker or Trek.

               Prior to Closing, Watsco hereby irrevocably and unconditionally
        consents to submit to the jurisdiction of both the courts of the state
        of Wisconsin and of the United Sates of America located in the State of
        Wisconsin for any actions, suits or proceedings arising out of or
        relating to this Section 6.1 (and agrees not to commence any action,
        suit or proceeding relating thereto except in such courts), and further
        agrees that service of any process, summons, notice or document by U.S.
        registered mail to Watsco's address set forth in Section 11.1 shall be
        effective service of process for any action, suits or proceedings
        brought against Watsco in any such court. Prior to Closing, Watsco
        irrevocably and unconditionally: (a) waives any objection to the laying
        out of venue of any action, suit or proceeding arising out of this
        Section 6.1, in either the courts of the State of Wisconsin or of the
        United States of America located in Wisconsin, and (b) waives and agrees
        not to plead or claim in any such court that any action, suit or
        proceeding bought in any such court has been brought in an inconvenient
        forum.

               (c) Watsco agrees that, unless the Closing occurs, neither it nor
        any of its Affiliates may at any time prior to June 22, 1998, seek to
        employ or employ any person (other than hourly or non-exempt employees)
        who is at any time during such period employed by Baker or Trek, or
        otherwise directly or indirectly induce any employee of Trek or Baker to
        leave his or her employment, without the consent of Trek or Baker.

               (d) Following the Closing, the terms and conditions of Sections 
        6.1(b) and 6.1(c) shall be void and of no force or effect.

        SECTION 6.2 FURTHER ASSURANCES.

        Each party agrees to cooperate fully with the other parties hereto and
to execute and deliver or cause to be executed and delivered at all reasonable
times and places such additional instruments and documents as the other party
may reasonably request for the purpose of carrying out this Agreement.

        SECTION 6.3 HSR FILINGS.

        The parties acknowledge that they have made all filings, reports and
documents as may be necessary to comply with the HSR Act in connection with the
transaction contemplated by this Agreement. The parties shall cooperate with and
assist one another to take such action as may be reasonably required and as
permitted under Law in connection with such filings.

        SECTION 6.4 TAX AGREEMENTS.

               (a) SECTION 338(H)(10) ELECTION. Trek shall file and join (i)
        Watsco in timely making an election under Section 338(h)(10) of the Code
        (and any comparable election under state or local Tax Law) (collectively
        a "SECTION 338(H)(10) ELECTION") with respect to the purchase and sale
        of the Shares and (ii) and cooperate with Watsco in the completion and
        timely filing of such elections in accordance with the provisions of
        Treasury Regulations Section 1.338(h)(10)-1 (or any comparable
        provisions of state or local Tax Law) or any successor provision. Watsco
        will prepare and forward to Trek the appropriate forms and documentation
        related to such election within sixty (60) days after the final
        determination of the purchase price pursuant to Article II hereof. Each
        of Trek and Watsco represent and warrant to the other that it is
        qualified to make such an election. Trek shall pay any Tax attributable
        to the making of the Section 338(h)(10) Election and will indemnify
        Watsco, Baker and ISI against any Losses and Liabilities arising out of
        any failure to pay such Tax. Trek, with respect to the sale of the
        Shares and with respect to (i) those states or local jurisdictions whose
        laws adopt the provisions of the Code or whose laws provide for an
        election substantially similar to the election available under Section
        338(h)(10) of the Code shall pay any state or local Tax and indemnify
        Watsco, Baker and ISI against any Losses and Liabilities arising out of
        any failure to pay Tax attributable to such election (or which results
        from the making of such election) and (ii) those states or local
        jurisdictions whose laws do not adopt the provisions of the Code and do
        not provide for an election substantially similar to the election
        available under Section 338(h)(10) of the Code, shall pay any State
        Section 338(h)(10) Proxy Tax and indemnify Watsco, Baker and ISI against
        any Losses and Liabilities arising out of any failure to pay such State
        Section 338(h)(10) Proxy Tax. As used herein, "STATE SECTION 338(H)(10)
        PROXY TAX" shall mean the lesser of (x) any state or local Tax
        attributable to an election or deemed election under state or local law
        substantially similar to an election available under Section 338(g) of
        the Code (or which results from the making of an election under Section
        338(g) of the Code) with respect to the sale of the Shares, or (y) the
        actual amount of any state or local Tax imposed on Trek, Baker and ISI
        with respect to the sale of the Shares.

               (b) ALLOCATION OF PURCHASE PRICE. Trek and Watsco agree that the
        Purchase Price and the liabilities of Baker and ISI (plus other relevant
        items) will be allocated to the assets of Baker for all purposes
        (including Tax and financial accounting purposes) in a manner consistent
        with the fair market values of the assets. Within sixty (60) days of the
        date that the Purchase Price is finally determined in accordance with
        Article II, Watsco shall deliver to Trek, for its review and approval, a
        Schedule setting forth the allocation of the Purchase Price among the
        assets of Baker and ISI (the "ALLOCATION"). If Watsco and Trek are not
        able to agree to the Allocation within thirty (30) days, either of them
        may submit any unresolved matter related to the Allocation to the
        Settlement Accountants to resolve all unresolved matters related to the
        Allocation, and such resolution shall be binding on both parties. The
        fees and expenses of the Settlement Accountants shall be shared equally
        by Watsco and Trek. Trek and Watsco will file all Tax Returns (including
        amended returns and claims for refund) and information reports in a
        manner consistent with the Allocation.

               (c) ELECTION TO FILE A CONSOLIDATED TAX RETURN. The Affiliated
        Group of which Trek is the parent will file a federal consolidated tax
        return within the meaning of Treasury Regulations ss.1.1502-75 for the
        taxable year in which the sale of the Shares occurs.

               (d) RETURNS AND INCLUSION OF INCOME FOR PERIODS THROUGH THE
        CLOSING DATE. Trek shall file the Tax Returns for and include the income
        of Trek, Baker and ISI, respectively, (including any deferred income
        triggered into income by Regulation Section 1.1502-13 and Regulation
        Section 1.1502-14 and any excess loss accounts taken into income under
        Regulation Section 1.1502-19) on Trek's federal consolidated Tax Returns
        and on all other Tax Returns for all periods through the Closing Date
        and pay any Taxes attributable to such income. Except as otherwise
        expressly provided herein, Trek shall be responsible for and indemnify
        Watsco for all Taxes of Baker and ISI and for preparing and filing all
        Tax Returns with respect to Baker and ISI for all periods prior to or
        ending on the Closing Date, and Watsco shall be responsible for and
        indemnify Trek for all Taxes of Baker and ISI and for preparing and
        filing all Tax Returns with respect to Baker and ISI for all period
        commencing after the Closing Date. Any refunds in respect of Tax Returns
        with respect to Baker and ISI filed for all periods commencing prior to
        and ending on the Closing Date shall be for the account of Trek. Any
        refunds in respect of such Tax Returns filed for all periods commencing
        on the Closing Date and ending thereafter shall be for the account of
        Watsco. With respect to any Tax period that begins on or before and ends
        after the Closing Date (a "STRADDLE PERIOD"), for purposes of
        apportioning a Tax with respect to Baker and ISI, the portion of such
        Tax period that ends on the Closing Date shall be apportioned to Trek
        and the parties shall treat the Closing Date as the last day of such
        period; and the Tax for the Tax period that is allocated to that portion
        of the Tax period ending on the Closing Date shall be (i) in the case of
        a Tax that is based on income or gross receipts, the Tax that would be
        due with respect to the period ending on (and including) the Closing
        Date, based on actual operations of Baker and ISI during such period as
        shown on their books and records, and (ii) in the case of a Tax that is
        not based on income or gross receipts (E.G., real estate or franchise
        tax), the total Tax for the Straddle Period multiplied by a fraction,
        the numerator of which is the number of 

                                       40
<PAGE>



        days in the Tax period ending on (and including) the Closing Date and
        the denominator of which is the total number of days in the Straddle
        Period.

               (e) COOPERATION. Trek and Watsco shall reasonably cooperate, and
        shall cause their respective Affiliates, officers, employees, agents,
        auditors and Representatives reasonably to cooperate, in preparing and
        filing all Tax Returns, including, but not limited to, maintaining and
        making available to each other all records necessary in connection with
        Taxes and in resolving all disputes and audits with respect to all
        taxable periods relating to Taxes. Watsco shall furnish Tax information
        to Trek for inclusion in all Trek's Tax Returns for all periods which
        include the Closing Date. Without limiting the generality of the
        forgoing, Watsco shall retain, and shall cause Baker and ISI to retain,
        and Trek shall retain, until the applicable statute of limitations
        (including any extensions) have expired, copies of all Tax Returns,
        supporting work schedules, and other records or information that may be
        relevant to such Tax Returns for all tax periods or portions thereof
        ending before or including the Closing Date and shall not destroy or
        otherwise dispose of any such records without first providing the other
        party with a reasonable opportunity to review and copy same at the cost
        of such other party. Watsco shall give Trek prompt notice of any audit
        or similar investigation or proceeding in which the IRS or any other
        Governmental Authority makes or proposes to make, or in which Watsco has
        reason to believe that the IRS or any other Governmental Authority will
        make, or proposes to make, a Tax adjustment affecting the liability of
        Taxes of Trek, Baker, ISI or any Affiliate of Trek with respect to a
        pre-Closing tax period. If such Tax adjustment or the manner in which it
        is to be settled or compromised relates solely to or solely affects the
        liability for Taxes or any item or income, deduction, credit, basis, tax
        accounting method, gain, or loss ("TAX ATTRIBUTES") of Trek, Baker or
        ISI for any period ending on or prior to the Closing Date, Trek shall
        conduct and control all aspects of the Audit, including the settlement
        or compromise thereof. Furthermore, in the event any such Tax adjustment
        with respect to Trek, Baker or ISI results in a refund of Taxes to
        Watsco, Baker, ISI or any of their Affiliates with respect to any period
        ending on or prior to the Closing Date or in the event Watsco, Baker or
        ISI or any of their Affiliates receives a refund of Taxes with respect
        to any Tax Attribute of Trek, Baker or ISI for any such period, the
        amount of such refund shall be paid within five days to Trek by Watsco
        or an Affiliate of Watsco upon receipt of such refund by Watsco, Baker
        or ISI or any of their Affiliates.

               (f) AMENDED RETURNS. Trek shall be responsible for filing any
        amended consolidated, combined or unitary Tax Returns related to Baker
        or ISI for all periods ending on or before the Closing Date which are
        required as a result of examination adjustments made by the Internal
        Revenue Service or by the applicable state, local or foreign taxing
        authorities for such taxable years as finally determined. For those
        jurisdictions in which separate Tax Returns are filed by Baker or ISI,
        any required amended returns resulting from such examination
        adjustments, as finally determined, shall be prepared by Trek and
        furnished to Watsco, or its successor, for approval (which approval
        shall not be unreasonably withheld or delayed), signature and filing at
        least 30 days prior to the due date for filing such returns. Nothing in
        this Agreement shall require Trek to amend any Tax Return, other than as
        set forth above.

               (g) ORDINARY CONDUCT. On the Closing Date, Watsco shall cause
        Baker and ISI to conduct its businesses in the ordinary course in
        substantially the same manner as presently conducted and on the Closing
        Date shall not permit Baker and ISI to effect any extraordinary
        transactions on the Closing Date (other than any such transactions
        expressly required by applicable law or expressly permitted by this
        Agreement) that could result in Tax Liability to Baker or ISI for
        periods on or before the Closing Date in excess of Tax Liability
        associated with the conduct of its business in the Ordinary Course of
        Business.

               (h) TAX SHARING AGREEMENTS. Trek shall cause the provisions of
        any Tax sharing agreement or policy between Trek and any of its
        Affiliates (other than Baker or ISI), on the one hand, and Baker, on the
        other hand, to be terminated on or before the Closing Date.

               (i) TAXES OF OTHER PERSONS. Trek shall be responsible for and pay
        any Liability of Baker and ISI for Taxes of Trek or any of its
        Affiliates other than Baker and ISI under Regulation Section 1.1502-6
        (or any similar provisions of state, local or foreign law attributable
        to periods ending on or prior to the Closing Date).

        SECTION 6.5 REASONABLE EFFORTS TO CLOSE.

        Each party shall use commercially reasonable efforts to (a) take or
cause to be taken all actions, and do or cause to be done all things, which are
necessary, proper or advisable to cause any other party's conditions set forth
in Articles VII and VIII to be fully satisfied (but not waived), including, but
not limited to, in the case of Trek, making commercially reasonable efforts to
obtain the consents listed on SCHEDULE 3.11(B)(2), and (b) consummate and make
effective as promptly as practicable the transactions contemplated by this
Agreement, including using commercially reasonable efforts to obtain the
consents and approvals referred to in Sections 7.7 and 8.6.

        SECTION 6.6 COOPERATION IN LITIGATION.

        Each party hereto will reasonably cooperate with the other party hereto
in the defense or prosecution of any litigation or proceeding (or order or
settlement in connection therewith) already instituted or which may be
instituted hereafter against or by any party hereto relating to or arising out
of the conduct of business of Baker or of ISI prior to the date hereof (other
than litigation arising out of the transactions contemplated by this Agreement).
The party requesting such cooperation shall pay the out-of-pocket expenses
(including, but not limited to, reasonable attorneys' fees and expenses) of the
party providing such cooperation and of its employees and agents reasonably
incurred in connection with providing such cooperation, but shall not be
responsible to reimburse the party providing such cooperation for the salaries
or costs of fringe benefits or other similar expenses paid by the party
providing such cooperation to its employees and agents while assisting in the
defense or prosecution of any such litigation or proceeding. Notwithstanding the
foregoing, this Section 6.6 shall not apply to any litigation which is the
subject of a claim for indemnification pursuant to Article IX hereof.

ISI, and all monies owing by Baker or ISI to Trek (other than amounts owing
under this Agreement or the Related Agreements and the matters contemplated by
Article II), will be forgiven and canceled without any further action by Trek or
by Watsco, Baker or ISI. All other obligations of Trek to Baker or to ISI, or of
ISI or Baker to Trek, will be terminated effective as of Closing (other than the

contemplated by Article II) without any further action by Trek or by Watsco,
Baker or ISI.

following consummation, or (c) adversely affect the right of Watsco to own,

                                       45
<PAGE>



        SECTION 8.7 OTHER ASSURANCES.

        Watsco shall have delivered to Trek such other and further certificates,
assurances and documents as Trek may reasonably request in order to evidence the

                                   ARTICLE IX
                          SURVIVAL AND INDEMNIFICATION

        SECTION 9.1 SURVIVAL.

               (a) (i) The falsity or incorrectness of or breach of any
        representation or warranty of Trek or any of its Affiliates in this
        Agreement, any Related Agreement or in any schedule, certificate or
        agreement furnished to Watsco by or on behalf of Trek or any of its
        Affiliates pursuant to this Agreement or (ii) the matters described on
        SCHEDULE 9.2(A)(II); or

               (b) the failure by Trek or any of its Affiliates to perform any

        Agreement, any Related Agreement or under any schedule, certificate or

arising out of:

               (a) The falsity or incorrectness of or breach of any

        Agreement, any Related Agreement or in any schedule, certificate or
        agreement furnished to Trek by or on behalf of Watsco or any of its
        Affiliates pursuant to this Agreement; or

                                       46
<PAGE>



               (b) the failure by Watsco or any of its Affiliates to perform any
        covenant or agreement of Watsco or any of its Affiliates under this
        Agreement, any Related Agreement or under any schedule, certificate or
        agreement furnished to Trek by or on behalf of Watsco or any of its
        Affiliates pursuant to this Agreement.

        SECTION 9.4 METHOD OF ASSERTING CLAIMS.

        All claims for indemnification by any Indemnified Party under this
Article IX shall be asserted and resolved as follows:

               (a) THIRD PARTY CLAIMS. If any claim or demand in respect of
        which an Indemnified Party might seek indemnity under this Article IX is
        asserted against such Indemnified Party by a Person (a "THIRD PARTY
        CLAIM") other than Trek or Watsco (it being understood that claims of
        Affiliates of Trek and Watsco shall not be considered Third Party
        Claims), the Indemnified Party shall give written notice and the details
        thereof including copies of all relevant pleadings, documents and
        information and (if then known) the amount or the method of computation
        of the amount of such claim (collectively a "THIRD PARTY CLAIM NOTICE")
        to the Indemnifying Party within a period of thirty (30) days following
        the assertion of the Third Party Claim against the Indemnified Party
        (the "THIRD PARTY CLAIM NOTICE PERIOD"), PROVIDED, that a Third Party
        Claim Notice in respect of any action at law or suit in equity by or
        against a third person as to which indemnification will be sought shall
        be given as promptly as practicable after the action or suit is
        commenced. If the Indemnified Party fails to provide the Third Party
        Claim Notice within the Third Party Claim Notice Period, the
        Indemnifying Party will not be obligated to indemnify the Indemnified
        Party with respect to such Third Party Claim to the extent that the
        Indemnifying Party's ability to defend has been prejudiced by such
        failure of the Indemnified Party. The Indemnifying Party will notify the
        Indemnified Party within a period of thirty (30) days after its receipt
        of the Third Party Claim Notice by the Indemnifying Party (the "THIRD
        PARTY CLAIM RESPONSE PERIOD"):

                           (i) Whether the Indemnifying Party disputes its
               liability to the Indemnified Party under this Article IX with
               respect to such Third Party Claim; and

                          (ii) whether the Indemnifying Party desires, at its
               sole cost and expense, to defend the Indemnified Party against
               such Third Party Claim.

               If the Indemnifying Party notifies the Indemnified Party within
        the Third Party Claim Response Period that the Indemnifying Party
        desires to defend the Indemnified Party against the Third Party Claim,
        then the Indemnifying Party at its sole cost and expense shall defend,
        with counsel reasonably satisfactory to the Indemnified Party, such
        Third Party Claim by all appropriate proceedings, which proceedings will
        be diligently prosecuted to a final conclusion or, at the discretion of
        the Indemnifying Party, will be paid, compromised, or settled (with the
        consent of the Indemnified Party which shall not be unreasonably
        withheld or delayed). The Indemnified Party will cooperate in such
        defense at the sole cost and expense of the Indemnifying Party and shall
        furnish records, information and testimony and attend such conferences,
        discovery proceedings, hearings, 

                                       47
<PAGE>



        trials and appeals as may be reasonably requested by the Indemnifying
        Party in connection therewith. The Indemnified Party may, at its sole
        cost and expense, at any time prior to the Indemnifying Party's delivery
        of the notice referred to in the last sentence of the preceding
        paragraph, file any pleadings or take any other action that the
        Indemnified Party reasonably believes to be necessary or appropriate to
        protect its interests. The Indemnified Party, at its expense, may
        participate in, but not control, any defense or settlement of any Third
        Party Claim conducted by the Indemnifying Party pursuant to this Section
        9.4(a).

               If the Indemnifying Party fails to notify the Indemnified Party
        within the Third Party Claim Response Period that the Indemnifying Party
        desires to defend the Third Party Claim or if the Indemnifying Party
        gives such notice but fails to prosecute diligently or settle the Third
        Party Claim, then the Indemnified Party shall defend, at the sole cost
        and expense of the Indemnifying Party, the Third Party Claim by all
        appropriate proceedings, which proceedings will be prosecuted by the
        Indemnified Party in a reasonable manner and in good faith and will not
        be paid, compromised or settled (without the consent of the Indemnifying
        Party which shall not be unreasonably withheld or delayed). The
        Indemnifying Party shall, at its sole cost and expense, cooperate in
        such defense and shall furnish records, information and testimony and
        attend such conferences, discovery proceedings, hearings, trials and
        appeals as may be reasonably requested by the Indemnifying Party in
        connection therewith. Notwithstanding the foregoing provisions of this
        paragraph, if the Indemnifying Party is determined not to be liable for
        such Third Party Claim pursuant to the last paragraph of this Section
        9.4(a) and Section 9.4(c), the Indemnifying Party will not be required
        to bear the costs and expenses of the Indemnified Party's defense or the
        Indemnifying Party's participation therein pursuant to this paragraph,
        and the Indemnified Party will reimburse the Indemnifying Party in full
        for all reasonable costs and expenses incurred by the Indemnifying Party
        in connection with such defense.

               If the Indemnifying Party notifies the Indemnified Party that it
        does not dispute its liability to the Indemnified Party with respect to
        the Third Party Claim under this Article IX or fails to notify the
        Indemnified Party within the Third Party Claim Response Period whether
        the Indemnifying Party disputes its liability to the Indemnified Party
        with respect to such Third Party Claim, the actual Losses of the
        Indemnified Party as finally determined will be conclusively deemed a
        liability of the Indemnifying Party under this Article IX, and the
        Indemnifying Party shall pay the amount of such Losses to the
        Indemnified Party on demand. If the Indemnifying Party notifies the
        Indemnified Party within the Third Party Claim Response Period that the
        Indemnifying Party disputes its liability to the Indemnified Party with
        respect to such claim, the Indemnifying Party and the Indemnified Party
        will proceed in good faith to negotiate a resolution of such dispute,
        and if not resolved through negotiations within a period of thirty (30)
        days from the date of such notice, either party may require that such
        dispute be resolved by arbitration in accordance with Section 9.4(c)
        hereof.

               Notwithstanding anything in Section 9.4(a) to the contrary, with
        respect to the matters subject to indemnification under Section
        9.2(a)(ii), (i) no Third Party Claims Notice need be given by Watsco,
        and (ii) Watsco shall control the negotiations and any 

                                       48
<PAGE>



        defense of such matters in a reasonable manner and in good faith, and
        shall not pay, compromise or settle any such matter without the prior
        written consent of Trek (which shall not be unreasonably withheld or
        delayed), it being understood that costs and expenses incurred by Watsco
        related to such matters shall be Losses for which Watsco shall be
        entitled to indemnification under Section 9.2(a)(ii), subject to Section
        9.6.

               (b) OTHER CLAIMS. In the event any Indemnified Party should have
        a claim under this Article IX against any Indemnifying Party that does
        not involve a Third Party Claim or a claim under Article II for a
        purchase price adjustment (which Article contains its own applicable
        dispute resolution mechanism), the Indemnified Party shall promptly give
        written notice and the details thereof, including copies of all relevant
        information and documents and (if then known) the amount or method of
        computation of the amount of such claim (collectively, an "INDEMNITY
        NOTICE"), to the Indemnifying Party within a period of thirty (30) days
        following the discovery of the claim by the Indemnified Party (the
        "CLAIM NOTICE PERIOD") and shall furnish records, information and
        testimony and attend such conferences, discovery proceedings, hearings,
        trials and appeals as may be reasonably requested by the Indemnifying
        Party in connection therewith. The failure by any Indemnified Party to
        give the Indemnity Notice within the Claim Notice Period shall not
        impair the Indemnified Party's rights hereunder except to the extent
        that an Indemnifying Party demonstrates that it has been prejudiced
        thereby. The Indemnifying Party shall notify the Indemnified Party
        within a period of thirty (30) days after the receipt of the Indemnity
        Notice by the Indemnifying Party (the "INDEMNITY RESPONSE PERIOD")
        whether the Indemnifying Party disputes its liability to the Indemnified
        Party under this Article IX with respect to such claim. If the
        Indemnifying Party notifies the Indemnified Party that it does not
        dispute the claim described in such Indemnity Notice or fails to notify
        the Indemnified Party within the Indemnity Response Period whether the
        Indemnifying Party disputes the claim described in such Indemnity
        Notice, the actual Losses as finally determined will be conclusively
        deemed to be a liability of the Indemnifying Party under this Article IX
        and the Indemnifying Party shall pay the amount of such Losses to the
        Indemnified Party on demand. If the Indemnifying Party notifies the
        Indemnified Party within the Indemnity Response Period that the
        Indemnifying Party disputes its liability with respect to such claim,
        the Indemnifying Party and the Indemnified Party shall proceed in good
        faith to negotiate a resolution of such dispute, and if not resolved
        through negotiations within a period of thirty (30) days from the date
        of such notice, either party may require that such dispute be resolved
        by arbitration in accordance with Section 9.4(c) hereof.

               (c) RESOLUTION OF DISPUTES. Any dispute to be submitted to
        arbitration pursuant to this Section 9.4 shall be finally and
        conclusively determined in accordance with the Commercial Arbitration
        Rules of the American Arbitration Association (the "RULES OF
        ARBITRATION") then in effect by the decision of one (1) arbitrator (the
        "BOARD OF ARBITRATION") selected in accordance with the Rules of
        Arbitration. The Arbitration shall be held in Coconut Grove, Florida and
        the arbitrator shall render its decision in writing with respect to and
        stating the amount, if any, which the Indemnifying Party is required to
        pay to the Indemnified Party in respect of the claim made by the
        Indemnified Party. To the extent practical, the decision of the
        arbitrator shall be rendered no more than thirty (30) days following
        commencement of proceedings with respect thereto. The arbitrator 

                                       49
<PAGE>



        shall cause its written decision to be delivered to the Indemnified
        Party and the Indemnifying Party. Any decision made by the arbitrator
        (either prior to or after the expiration of such thirty (30) day period)
        shall be final, binding and conclusive on the Indemnified Party and the
        Indemnifying Party and entitled to be enforced to the fullest extent
        permitted by law and entered in any court of competent jurisdiction.

               Trek and Watsco each hereby consent to the non-exclusive
        jurisdiction of the foregoing arbitrator and to the non-exclusive
        jurisdiction of any local, state or federal court located in the State
        of Florida for the purpose of enforcing the decision or award of the
        arbitrator or otherwise. Trek and Watsco agree that all service of
        process may be made on any such party by personal delivery or by
        registered or certified mail addressed to the appropriate party at the
        address for such party set forth in Section 11.1 hereof.

               All fees, costs and expenses of the Indemnified Party and the
        Indemnifying Party in relation to the arbitration, including, but not
        limited to, attorneys' fees shall be paid by such parties as determined
        by the arbitrator. Each and every arbitration proceeding commenced
        pursuant to this Section 9.4(c) shall be consolidated with any

        Section 9.4(c).

        SECTION 9.5 CONTINUED LIABILITY FOR INDEMNITY CLAIMS.

        The liability of any Indemnifying Party hereunder with respect to claims
hereunder shall continue for so long as any claims for indemnification may be

indemnification claims duly and timely made, thereafter until the Indemnifying
Party's liability therefor is finally determined and satisfied.

        SECTION 9.6 LIMITATIONS ON INDEMNIFICATION.

               (a)     CERTAIN TYPES OF DAMAGES.  No Indemnifying Party shall

               (c) LIMITATION ON RECOVERY. Recovery by Watsco and its Affiliates
        under Section 9.2 shall be limited, in the aggregate, to no more than
        Five Million Dollars ($5,000,000), with the exception of claims based
        upon Section 3.7, Section 3.19 (only to the extent it relates to a

        matters of title to the Shares included in the Section 3.4(a), Sections
        5.3, 5.4, 5.5 and 6.4, Article II and the Noncompetition Agreement.

        defined contribution plan), representations and warranties regarding
        matters of title to the Shares in Section 2.4(a), Section 5.3, Section

        hereunder (grossed up for any Tax incurred on such increase) and (ii)
        reduced to take account of any proceeds of insurance received by the
        Indemnified Party and of any net Tax Benefit realized or realizable by
        the Indemnified Party arising from the incurrence or payment of any such
        Loss. In computing the amount of any such Tax Cost or Tax Benefit, the
        Indemnified Party shall be deemed to have recognized all other items of
        income, gain, loss, deduction or credit before recognizing any item
        arising from the receipt of any indemnity payment hereunder or the
        incurrence or payment of any indemnified claim.

               (e) ADDITIONAL LIMITATIONS ON INDEMNIFICATION. To the extent that
        Watsco has or gains knowledge prior to the Closing Date of any breach of
        any representation or warranty set forth in Article III hereof other
        than from Trek or Baker, Watsco shall promptly notify Trek of such
        breach, and in the event Watsco does not so notify Trek, the amount of
        Losses incurred in connection with or arising from such breach shall be
        reduced by the amount of Losses, if any, that could reasonably have been
        prevented by Trek if it had received prompt notice of such breach. For
        purposes of this Section 9.6, the knowledge of Watsco shall mean the
        actual knowledge of executive officers of Watsco.

               (f) ADDITIONAL LIMITATIONS REGARDING 9.2(A)(II). Recovery by
        Watsco and its Affiliates under Section 9.2(a)(ii) shall be limited, in
        the aggregate, to no more than One Million Five Hundred Thousand Dollars
        ($1,500,000). In addition, once the $250,000 threshold limitation
        established in Section 9.6(b)(ii) has been satisfied, Watsco and its
        Affiliates shall only be entitled to indemnification for 50% of its and
        their Losses under Section 9.2(a)(ii).

        SECTION 9.7 TIME LIMITS ON CLAIMS.

any Indemnified Party under Section 9.2(a)(i), 9.2(b) or 9.3 may be made only
prior to May 1, 1998 with the exception of (a) Sections 3.7 and 3.19 (only with

with respect to which such representations and warranties shall survive and
claims thereon may be made for 

                                       51
<PAGE>



three (3) years following the Closing Date; and (c) representations and 
warranties regarding matters of title to the Shares included Section 3.4(a) of 
this Agreement with respect to which such representations and warranties shall 
survive and claims thereon may be made without any limitation as to time. 
Notwithstanding anything in this Agreement to the contrary, a claim by any 
Indemnified Party under Section 9.2(a)(ii) may only be made for three (3) years 
following the Closing Date.

        Notwithstanding anything in this Agreement to the contrary, any claim
pursuant to Sections 9.2 or 9.3 not made within the foregoing relevant time
period shall expire and be forever barred thereafter.

        SECTION 9.8 REMEDIES.

        Notwithstanding anything contained herein to the contrary, it is
specifically understood and agreed that in the event a misrepresentation or
breach of warranty or covenant by Trek is discovered by Watsco after the
Closing, the remedy of Watsco shall be limited to the indemnification as set
forth in Article IX, and Watsco shall not be entitled to a recession of this
Agreement.

        SECTION 9.9 SOURCES OF PAYMENT.

        To the extent any party hereto or any of its Affiliates is entitled to
indemnification for Losses under this Article IX and such entitlement has either
not been disputed by the other party hereto within the time periods established
in this Article IX or any dispute related thereto has been resolved in favor of
such party in accordance with this Article IX (and such resolution has become
final and non-appealable), then such party or Affiliate may (but shall not be
required to) set off such amounts against (and deduct them from) any amounts
owing to the other party or any of its Affiliates under this Agreement or any
Related Agreement but only with respect to any indemnification right which has
been so resolved and become final and non-appealable. The foregoing right is in
addition to any other rights that the parties may have for indemnification.


                                    ARTICLE X
                                   TERMINATION

        SECTION 10.1 GROUNDS FOR TERMINATION.

        This Agreement may, by written notice given prior to or at the Closing,
be terminated:

               (a) By either Watsco or Trek if a material breach of any
        provision of this Agreement has been committed by the other party and
        such breach has not been waived or has not been cured within ten (10)
        Business Days of the date such notice was given;

               (b)(i) by Watsco if any of the conditions in Article VII have not
        been satisfied as of the Closing Date or if satisfaction of such
        condition is or becomes impossible (other than through the failure of
        Watsco to comply with its obligations under this Agreement) and Watsco
        has not waived such condition in writing on or before the Closing Date;
        or 

                                       52
<PAGE>



        (ii) by Trek, if any of the conditions in Article VIII have not been
        satisfied as of the Closing Date or if satisfaction of such a condition
        is or becomes impossible (other than through the failure of Trek to
        comply with its obligations under this Agreement) and Trek has not
        waived such a condition in writing on or before the Closing Date;

               (c) by mutual consent of Watsco and Trek; or

               (d) by either Watsco or Trek if the Closing has not occurred
        (other than through the failure of any party seeking to terminate this
        Agreement to comply fully with its obligations under this Agreement) on
        or before December 31, 1997, or such later date as the parties may agree
        upon.

        SECTION 10.2 EFFECT OF TERMINATION.

        Each party's right of termination under Section 10.1 is in addition to
any other rights it may have under this Agreement or otherwise, and the exercise
of a right of termination will not be an election of remedies. If this Agreement
is terminated pursuant to Section 10.1, all further obligations of the parties
under this Agreement will terminate, except that the obligations in Sections 6.1
and 11.2 will survive termination unimpaired; PROVIDED, HOWEVER, that, if this
Agreement is terminated by a party because of the breach of the Agreement by the
other party or because one or more of the conditions to the terminating party's
obligations under this Agreement is not satisfied as a result of the other
party's failure to comply with its obligations under this Agreement, the
terminating party's right to pursue the legal remedies will survive such
termination unimpaired.

        Any provision of this Agreement which is prohibited or unenforceable in

party or parties upon final judgment on the merits reasonable attorneys' fees
(and sales taxes thereon, if any), including attorneys' fees for any appeal and
costs incurred in bringing such suit or proceeding. Each party to this Agreement
consents to the non-exclusive jurisdiction of the state courts of the State of
Florida and to the U.S. District Courts for any district in Florida (and to the

        SECTION 11.16 SPECIFIC PERFORMANCE.

        Each of the parties hereto acknowledges that the rights of each other
party to consummate the transactions contemplated by this Agreement are special,
unique and of extraordinary character and that, in the event that a party
violates or fails and refuses to perform any covenant or agreement made by it in
this Agreement, then each other party may be without an adequate remedy at law.
Each party agrees, therefore, that in the event it violates or fails and refuses
to perform any covenant or agreement made by it in this Agreement, each other
party may, in addition to any remedies hereunder for damages or other relief,
institute and prosecute an action 

                                       56
<PAGE>



in any court of competent jurisdiction to enforce specific performance of such 
covenant or agreement or seek any other equitable relief.

        SECTION 11.17 RIGHT TO CURE BREACHES.

        Either party shall have the right to seek to cure any breach of any
representation, warranty or covenant made by it in this Agreement to the
attachments hereto; PROVIDED, that no such cure shall affect any rights to
indemnification for Losses incurred in connection with or arising out of any
such breach and PROVIDED FURTHER that any such cure shall be effected within ten
(10) Business Days following notice of such breach. Each party shall cooperate
with the other in connection with any attempt to cure any such breach,
including, but not limited to, providing such other party, its employees and
representatives, access to any necessary books and records and making available
any necessary personnel at the breaching party's sole cost and expense.

        SECTION 11.18 INTEREST.

        All payments owing under this Agreement by any party which are not paid
when due shall bear interest calculated at a per annum rate of 7% (or, if less,
the highest rate allowed by applicable Law) from the due date thereof until
paid. (It is understood by the parties this Section 11.18 is not intended to,
and does not, mean that interest shall be owing by one party to the other with
respect to funds while they are held by the Escrow Agent under the Escrow
Agreement.)
