Shareholder shall be employed as president or other senior officer of Buyer and
chief executive officer of the Acquired Business division of Buyer (which may be
called the JEH division), which employment agreement shall be in the form of,

Agreement"). At the Closing, Buyer will offer employment to E.G. Helzer,
Shareholder's brother,


                                        4





pursuant to an employment agreement which shall be in the form of, and contain
the terms set forth in, Exhibit 1.5(b) (the "E.G. Helzer Employment Agreement").

         1.6 Initial Public Offering. If (a) within five (5) years after June
30, 1997, a company controlled by TDA Industries, Inc. files a Registration
Statement that is declared effective by the SEC which registers the common stock
of its roofing supply business (the "Roofing Company") for sale in connection
with an underwritten initial public offering of at least 10% of the Roofing
Company's then-outstanding common stock "(IPO"), and such stock is in fact sold
in such IPO, (b) the operations of the Acquired Business are part of the Roofing
Company's operations at the time of the effective date of such filing, (c) the
Acquired Business' earnings before interest, federal income taxes, depreciation
and amortization ("EBITDA") from July 1, 1997 to the effective date of such
filing are:

                  (i) not less than Three Million Eight Hundred
                      Thousand Dollars ($3,800,000.00) per year
                      (the "First Alternative"); or

                 (ii) less than Three Million Eight Hundred
                      Thousand Dollars ($3,800,000.00) per year
                      but not less than Three Million Six Hundred
                      Thousand Dollars ($3,600,000.00) per year
                      (the "Second Alternative");

(or, in the case of the First Alternative or Second Alternative, not less than a
seasonally adjusted portion of such amount for any partial fiscal year), and (d)
following the IPO, the Roofing Company's common stock is traded on a national
securities exchange or on NASDAQ, then Seller or its designee shall receive One
Million Three Hundred Fifty Thousand Dollars ($1,350,000.00), if the First
Alternative is met, or One Million Dollars ($1,000,000.00), if the Second
Alternative is met, payable, at the option of the Roofing Company, either in
cash, or in common stock of the Roofing Company valued at the price at which
such common stock is sold in the IPO. Such common stock delivered to Seller or
its designee pursuant to this Section 1.6 shall be issued subject to all normal
and customary agreements among the underwriters, the Roofing Company, and its
principal shareholders entered into in connection with the IPO, and to a lock-up
limited to no more than 24 months from the effective date of the IPO at the
discretion of the underwriters of such IPO, or any greater period of time that
may be required by any regulatory agency, share exchange, or NASDAQ. In the
event that Seller or its designee provides the Roofing Company notice, at least
30 days prior to the anticipated effective date of the IPO, that it would prefer
to receive the Roofing Company common stock, rather than cash, Buyer shall use
reasonable efforts to have such stock issued to Seller or its designee (subject
to the approval of the underwriters of such IPO). Buyer shall use reasonable
efforts to have Shareholder be given the opportunity, upon the consummation of
the IPO, to become a senior officer (other than chief executive officer) and a
director of the IPO company, in addition to such position(s) as he would
maintain with Buyer and the Acquired Business.

Exchange Commission under the Securities Act of 1933, as amended, in connection
with a public offering of the Roofing Company's common stock (other than a
registration statement filed on Form S-4 or Form S-8, or any form substituting

Inc., a Texas corporation ("Exports"), the stock of which is owned solely by
Shareholder, and Buyer shall enter into, and Shareholder shall cause Exports to

pursuant to which Buyer shall be the sole distributor of Exports of roofing

jointly and severally, represent and warrant to Buyer, as of the Closing Date,
and covenant with Buyer, as follows:

                  (a) Enterprises is a corporation duly organized, validly
existing, and in good standing under the laws of the State of Colorado.
Enterprises has full power to own its assets and to conduct its business as
presently conducted. Enterprises is not required to be authorized, qualified or
licensed to do business in any other state.

                  (b) Enterprises has all requisite power and authority to
execute and enter into this Agreement and all other agreements and instruments
contemplated hereby to be executed and delivered by Enterprises at the Closing
(the "Enterprises Document") and to perform its obligations hereunder and
thereunder. The execution, delivery and performance by Enterprises of this
Agreement and the Enterprises Documents have been duly authorized by all
necessary action, corporate or otherwise, by Enterprises and its stockholders.
This Agreement has been duly executed and delivered by Enterprises and its sole
shareholder, James E. Helzer, and is the legal, valid and binding agreement of
Enterprises, enforceable against Enterprises in accordance with its terms. The
Enterprises Documents will be, when executed and delivered by Enterprises, the
legal, valid and binding agreements of Enterprises enforceable against

                  (c) Except as set forth in Exhibit 1.8, Enterprises has no
assets of any nature.

                  (d) Enterprises has no debts, obligations or other
liabilities, whether express or implied, contingent or otherwise, or resulting
from any violation of law, rule or regulation, or arising out of any act,
omission or transaction of Enterprises.

                  (e) At the Closing, Enterprises shall sell, transfer and
assign to Buyer, for One Hundred Dollars ($100.00), and other good and valuable
consideration, all of the assets of Enterprises (including, without limitation,
its interest in any of the Third Party Leases and claims and choses in action),
under such documents of assignment and transfer as are acceptable to Buyer, in
its sole discretion, free and clear of all Encumbrances; provided, however, that
Buyer shall not 


                                        6





assume any contracts, leases (except as may be assumed expressly by Buyer in
writing), debts, obligations or liabilities of Enterprises, or arising out of
the ownership or operation of any of Enterprises' assets, whether express or
implied, contingent or otherwise, or resulting from any violation of law, rule
or regulation, or arising out of any act, or omission or transaction of
Enterprises, and Seller, Enterprises, Shareholder and Mrs. Helzer, jointly and
severally, shall indemnify and hold Buyer harmless with respect thereto.

         1.9 Manufacturers' Rebates. On or before March 1, 1998, Seller and
Buyer shall prorate, in accordance with the terms of this Section 1.9, the
volume rebates provided exclusively on an annual basis (for example, end of year
volume rebates which have not been previously credited or accrued) for calendar
year 1997 by the manufacturers listed on Exhibit 1.9. Seller's portion of such
annual rebate from any such manufacturer for calendar year 1997 shall be that
proportion of the annual rebate from such manufacturer for calendar year 1997 as
the dollar volume of purchases by Seller from such manufacturer during the first
six calendar months of 1997 ("Seller's Purchases") bears to the sum of (a)
Seller's Purchases and (b) the dollar volume of purchases by Buyer from such
manufacturer with respect to the Acquired Business during the balance of
calendar year 1997. Seller's share of the rebates, as determined under this
Section 1.9, will be paid to Seller as follows:

                  (i) by wire transfer in immediately available
                      funds of an amount not exceeding the sum of
                      (A) the difference between Two Hundred Fifty
                      Thousand Dollars ($250,000.00) and the
                      amount, if any, of the Additional Cash
                      Payment under Section 23(b)(i), and (B) One
                      Hundred Thousand Dollars ($100,000.00); and

                 (ii) if Seller's share of such rebates exceeds
                      the amount determined under clause (i)
                      above, the Promissory Note described in
                      Section 2.1 shall be amended by adding such
                      excess to the principal balance under the
                      Promissory Note.

         1.10 Employee Services Agreement. Contemporaneously with the execution
of this Agreement, Seller and Buyer have entered into an Employee Services
Agreement in the form of, and containing the terms set forth in, Exhibit 1.10.

2. Purchase Price and Payment; Allocation; and Sales and Transfer Taxes.

         2.1 Purchase Price and Payment. The purchase price for the Purchased
Assets, subject to adjustment under the terms of this Agreement (the "Purchase
Price"), shall be Fourteen Million Five Hundred Thousand Dollars
($14,500,000.00) (the "Tentative Purchase Price") plus the Adjustment Amount, as
defined in Section 2.2, if the Adjustment Amount is a positive number, or minus
the Adjustment Amount, if the Adjustment Amount is a negative number. At the
Closing, the Tentative Purchase Price, after applying the prorations, credits
and adjustments provided for in this Agreement (the "Adjusted Tentative Purchase
Price"), shall be payable as follows: (a) Buyer shall pay to Seller, by wire
transfer in immediately available United States funds, the sum of


                                        7





Thirteen Million Five Hundred Thousand Dollars ($13,500,000.00) (the "Closing
Cash Amount"); and (b) Buyer shall issue to Seller, Buyer's Secured
Non-Negotiable Promissory Note, in the form of, and containing the terms set
forth in, Exhibit 2.1(b)(1) to this Agreement for the balance of the Adjusted
Tentative Purchase Price (the "Promissory Note"). The Promissory Note shall be
secured by a Security Agreement in the form of, and containing the terms set
forth in, Exhibit 2.1(b)(2) (the "Security Agreement").

         In addition to the foregoing, Buyer shall pay at the Closing the first
Three Hundred Fifty Thousand Dollars ($350,000.00) of the fees of Geneva
Corporate Finance, Inc. ("Geneva"), Seller's broker, with respect to the
transactions under this Agreement (the "Broker Contribution"); provided,
however, that Geneva shall not be deemed to be the agent or broker of Buyer as a
result of such payment or otherwise.

         2.2 Adjustment Amount. The Adjustment Amount (which may be a positive
or negative number) will be equal to the difference between (a) the amount of
the Acquired Net Assets, as defined in this Section below, and (b) Fourteen
Million Two Hundred Twenty Six Thousand Dollars ($14,226,000.00). For purposes
of this Agreement, the "Acquired Net Assets" means the difference between (i)
the net book value of the Purchased Assets (other than the accrued portion of
the annual manufacturers' rebates receivable that are subject to proration under
Section 1.9), as finally determined on the Closing Balance Sheet, as defined in
Section 2.3(a), but excluding any Special Reserves, as defined in Section
2.4(c), up to One Million Nine Hundred Thousand Dollars ($1,900,000.00), and
(ii) the Assumed Liabilities, as finally determined on the Closing Balance
Sheet.

         2.3      Adjustment Procedure.

                  (a) Seller will prepare and shall cause Waters & Murray
("W&M"), Seller's independent certified public accountants, to audit the
financial statements (the "Closing Financial Statements") of Seller as of June
30, 1997, which Closing Financial Statements shall contain an audited balance
sheet (the "Closing Balance Sheet") at June 30, 1997, audited statements of
income and retained earnings, and cash flows for the period from the date of the
Balance Sheet, as defined in Section 5.7, through June 30, 1997, all prepared in
accordance with generally accepted accounting principles, and a separate
computation of the Acquired Net Assets. Buyer's independent certified public
accountants, Deloitte & Touche LLP ("D&T") and representatives of Buyer shall
review the audit conducted by W&M. Seller and Shareholder will arrange for D&T's
and Buyer's representatives to have full access to the W&M audit workpapers and
files. Seller and Shareholder also agree that representatives of D&T and Buyer
will be present to observe the physical inventory count taken by Seller and W&M
prior to June 30, 1997. Seller shall deliver the Closing Financial Statements to
Buyer and D&T within sixty (60) days after the Closing Date. If, within thirty
(30) days following delivery to Buyer and D&T of the Closing Financial 
Statements, Buyer has not given Seller notice of its objection to the Closing
Financial Statements (such notice, if given, must contain a statement of the
basis of Buyer's objection), then the Closing Financial Statements, including,
without limitation, the computation of the Acquired Net Assets, shall be deemed
to have been finally determined for purposes of this Agreement, and the Acquired
Net Assets as so determined will be


                                        8





used in computing the Adjustment Amount. If Buyer gives such notice of an
objection, then the matters as to which Buyer has objected will be submitted to
D&T and W&M (the "Accountants") for resolution, and the Accountants shall
determine the Acquired Net Assets. If the Accountants are unable to agree as to
the resolution of such matters and the Acquired Net Assets within thirty (30)
days after such matters are submitted to the Accountants, the Accountants shall
select another "Big Six" accounting firm (New York City or Dallas office) (the
"Other Accountants") which will resolve such matters and determine the Acquired
Net Assets. Each party will furnish to the Accountants (and, if applicable, the
Other Accountants) such workpapers and other documents and information relating
to the disputed matters as the Accountants or the Other Accountants may request
and are available to that party (or its independent public accountants), and
each party will be afforded the opportunity to present to the Accountants and
the Other Accountants any material relating to such disputed issues and to
discuss such issues with the Accountants and the Other Accountants. The
resolution of such issues under this Section 2.3 (a) by the Accountants or Other
Accountants, as the case may be, as set forth in a notice delivered to both
parties by the Accountants or Other Accountants shall be deemed to be a final
determination thereof for purposes of this Agreement, shall be binding and
conclusive on the parties, and the Acquired Net Assets, as finally determined by
the Accountants or Other Accountants, will be used in computing the Adjustment
Amount. Buyer and Seller shall each bear one-half of the fees of the Other

                         principal amount of the Promissory Note, 
                         Buyer shall pay the difference to Seller (up

                    (ii) if the Purchase Price is less than the sum 
                         of the Closing Cash Amount and the principal 
                         amount of the Promissory Note, Seller shall

                         pay) (A) the difference to Buyer (up to Two 
                         Hundred Fifty Thousand Dollars

                         and Buyer by reducing the principal balance 
                         of the Promissory Note by the amount of such 
                         excess (up to Two Hundred Fifty Thousand 
                         Dollars ($250,000.00)), and (C) Seller shall 
                         pay (and Shareholder shall cause Seller to

         2.4      Contingent Payments.

                  (a) Based on Modified EBITDA. Buyer shall pay to Seller or its
designee, as additional consideration for the sale of the Purchased Assets, the
applicable percentage set forth below of the Modified EBITDA, as defined in this
Section 2.4(a), of the Acquired Business, on an annual non-cumulative basis, for
each of the fiscal years ending June 30, 1998 through June 30, 2002:




         MODIFIED EBITDA FOR                         PERCENTAGE OF MODIFIED
         FISCAL YEAR                                 EBITDA TO BE PAID TO SELLER
         -------------------                         OR ITS DESIGNEE
                                                     -----------------------------
                                                  
         Less than $3,000,00.00                      0%

         $3,000,000.00 - $4,000,000.00               35%

         $4,000,001.00 - $5,000,000.00               40%

         More than $5,000,000.00                     50%


         For purposes of this Section, the Modified EBITDA of the Acquired
Business shall not be charged with any interest cost relating to the purchase of
the Acquired Business. The Modified EBITDA of the Acquired Business will be
conclusively determined annually by Buyer's independent certified public
accountants. For purposes of this Section 2.4(a), the "Modified EBITDA" means
the EBITDA of the Acquired Business for any fiscal year of Buyer minus the
capital expenditures during such fiscal year with respect to the Acquired
Business (which expenditures, for purposes of this Section 2.4(a), shall be
deemed not to exceed 50% of the depreciation expense of the Acquired Business
for such fiscal year), plus Fifty Thousand Dollars ($50,000.00) of the cash
compensation paid to Shareholder during such fiscal year under the J.E. Helzer
Employment Agreement.

         (b) Based on EBITDA.

                     (i) For any fiscal year during the period

                         until and including June 30, 2002 (the 
                         "Applicable Period") in which the EBITDA of 
                         the Acquired Business (plus $50,000.00 of 
                         the compensation paid to Shareholder under 
                         the J.E. Helzer Employment Agreement) 


                                       10

                         Thousand Dollars ($4,400,000.00), Buyer 
                         shall pay to Seller or its designee the sum 
                         of One Million Dollars ($1,000,000.00); 
                         provided, however, that Buyer shall not pay, 
                         and Seller shall not be entitled to receive, 
                         more than Two Million Dollars 
                         ($2,000,000.00) in the aggregate under this 
                         Section 2.4(b)(1).

                   (ii)  In the event that the aggregate EBITDA of 
                         the Acquired Business during the Applicable 
                         Period (plus $50,000.00 per fiscal year of 
                         the annual compensation paid to Shareholder 
                         under the J.E. Helzer Employment Agreement) 
                         is not less than Twenty Million Dollars 
                         ($20,000,000.00), Buyer shall pay to Seller

                         ($1,350,000.00), and (B) the difference, if 
                         any, between Two Million Dollars 
                         ($2,000,000.00) and the amount Seller or its 
                         designee is entitled to be paid under 
                         Section 2.4 (b) (1).

         All payments under this Section 2.4(b) shall bear simple interest at
the rate of 6% from July 1, 1997, to the date of payment.

             (c)     Based on Reduction of Accounts Receivable Reserves.

                     (i) Schedule 2.4(c)(i) contains a list, as of 
                         June 30, 1997, of certain account debtors of

                         Thousand Dollars ($600,000.00) (the "Regular 
                         Reserves"), that has been allocated to each 
                         Special Account Debtor, and (ii) that 
                         portion of the special reserves, of not less 
                         than One Million Seven Hundred Thousand 
                         Dollars ($1,700,000.00) (the "Special 
                         Reserves"), that has been allocated to each 
                         Special Account Debtor. The sum of the 
                         Regular Reserves and Special Reserves, on 
                         the Closing Balance Sheet (the "Total A/R 
                         Reserves"), will be not less than Two 
                         Million Three Hundred Thousand Dollars

                         Reserves and Special Reserves (i.e., the 
                         Total A/R Reserves), and the allocations of 
                         such Regular Reserves and Special Reserves to


                                       11





                         any or all Special Account Debtors on the 
                         Closing Balance Sheet, may vary from the 
                         Regular Reserves and Special Reserves and 
                         the allocations thereof contained in 
                         Schedule 2.4(c)(i).

                    (ii) Subject to the terms of this Section 2.4(c), 
                         if the portion of the Total A/R Reserves

                         Section 2.4(c)(i), is reduced by Buyer as of 
                         the end of any fiscal year during the 
                         Applicable Period, in accordance with GAAP, 
                         on Buyer's audited balance sheet, solely 
                         because of collections by Buyer with respect 
                         to such Special Account Debtors, then, the 
                         following provisions shall apply:

                             (A) Seller or its designee shall 
                         be paid 100% of such reductions until

                         than Two Million Five Hundred

                         (determined after taking into account 
                         such reductions).

                             (B) Then, Buyer shall retain 100% 
                         of such reductions until the Total 
                         A/R Reserves are not less than Two 
                         Million Three Hundred Thousand 
                         Dollars ($2,300,000.00) (determined 
                         after taking into account such 
                         reductions).

                             (C) Seller or its designee and 
                         Buyer shall share equally any such 
                         reductions at any time that the Total 
                         A/R Reserves are less than Two 
                         Million Three Hundred Thousand 
                         Dollars ($2,300,000.00).

                   (iii) Notwithstanding Section 2.4(c)(ii), 
                         Seller or its designee shall not be 
                         entitled to be paid, under Section 
                         2.4(c)(ii), any portion of a 
                         reduction in the Total A/R Reserves 
                         allocated to any Special Account 
                         Debtor under Section 2.4(c)(i) unless 
                         and until:

                             (A) the total balance of the 
                         Accounts Receivable of such Special 
                         Account Debtor as of the end of such 
                         fiscal year is less than the total 
                         balance of the Accounts

                         Overdue Balance of the Accounts 
                         Receivable of such Special Account 
                         Debtor to the total balance of the

                         (B), "Overdue Balance" means any 
                         balance not collected within 45 days

                    (iv) [INTENTIONALLY OMITTED]

                     (v) An example of the application of this
                         Section 2.4(c) is contained in Schedule
                         2.4(c)(v).

         2.5 Allocations. The consideration for the Purchased Assets will be
allocated in accordance with the Allocation of Purchase Price Agreement in the
form of, and containing the terms set forth in, Exhibit 2.5. Such allocations
will be conclusive and binding on Seller and Buyer for federal income tax
purposes, and Seller and Buyer will report such allocations to the Internal
Revenue Service as required by Section 1060 of the Internal Revenue Code of
1986, as amended, and the regulations with respect to that Section.

         2.6 Sales and Transfer Taxes. Seller shall pay (and Shareholder shall
cause Seller to pay) all sales and other transfer taxes and fees arising out of
the sale and assignment of the Purchased Assets to Buyer; provided, however,
that with respect to sales or other transfer taxes arising out of the sale or
transfer under this Agreement of motor vehicles under certificates of title,
Buyer shall pay such sales or other transfer taxes up to Fifty Thousand Dollars
($50,000.00) ("Buyer's Sales Tax Portion") and the balance, if any, of such
sales or other transfer taxes shall be shared by Seller and Buyer equally.
Seller shall pay (and Shareholder shall cause Seller to pay) all documentary and
other excise taxes with respect to the Promissory Note and any amendments
thereto.

3.       Casualty and Condemnation.

         3.1 Risk of Loss. Until the Closing, the risk of loss or damage to the
Purchased Assets shall be borne by Seller, and if the Purchased Assets or any
portion thereof are stolen or are damaged or destroyed by fire or other casualty
before the Closing and can be restored, repaired or replaced substantially in
the same condition as exists on the date of this Agreement, within ninety (90)
days 


                                       13





after such casualty, Seller shall so restore, and Shareholder shall cause 
Seller to restore, such Purchased Assets, and the Closing Date shall be 
extended accordingly; but if such uninsured portion of the cost of 
restoration, repair or replacement exceeds One Hundred Thousand Dollars 
($100,000.00) (and Seller refuses to restore, repair or replace such 
Purchased Assets), or such restoration, repair or replacement cannot be 
completed within such period, this Agreement, at the option of Buyer, shall 
be deemed terminated.

         If Buyer elects to purchase the Purchased Assets even though the
Purchased Assets are not restored, repaired or replaced, or the uninsured
portion of the cost of restoration, repair or replacement exceeds One Hundred
Thousand Dollars ($100,000.00), Buyer shall be entitled to the benefits of any
insurance on the Purchased Assets to the extent required for such restoration,
repair or replacement. Seller shall not be required to restore, repair or
replace the stolen, damaged or destroyed Purchased Assets if the uninsured
portion shall cost more than One Hundred Thousand Dollars ($100,000.00) or if it
will take longer than ninety (90) days to complete, but, if Buyer elects to go
forward with the purchase, Buyer will receive a credit against the Purchase
Price at the Closing for such uninsured portion of the loss and the restoration
and an assignment by Seller of all of its rights under insurance policies with
respect to the stolen, damaged or destroyed Purchased Assets and all other
rights and claims for damages with respect to such stolen property, damage or
destruction.

         3.2 Condemnation. If at any time prior to the Closing, the real
property of which the Leased Premises are a part, or any portion thereof, is
taken by eminent domain or if any preliminary steps in any taking by eminent
domain of such real property or the Leased Premises, or any portion thereof,

                  (a) Prorations as to Assumed Liabilities. Any rents and fees

                                       16




         unused deposits with respect to the Assumed Liabilities and will
         receive a credit in the amount thereof with respect to the Purchase
         Price

         determined as of June 30, 1997, then the taxes with respect to such
         Purchased Assets for the preceding calendar year, on the basis of no
         applicable discount, shall be used to calculate such prorations, with
         known changes in valuation or millage being applied. The prorated taxes
         shall be an adjustment to the amount of cash due from Buyer at the
         Closing. In the event the actual amount of any of such taxes should
         vary by more than One Hundred Dollars ($100.00) from estimates used at
         the Closing to prorate such taxes, then the parties shall re-prorate
         such taxes within ten (10) days following request by either party based

         statement, be charged an amount equal to the amount of all unpaid
         certified, confirmed and ratified special assessment liens with respect
         to each of the Leased Premises (if such assessments are the obligation
         of the tenant under the applicable lease) as of June 30, 1997 and, in
         the case of pending liens with respect to a parcel or the Leased
         Premises (if such liens would be the obligation of the tenant under the

         body of the assessment.

         the Leased Premises.

                  (b) Taxes/Assessments. Except as set forth in Schedule

         Assets or Leased Premises except for ad valorem real property taxes for
         the current calendar year which are not yet due and payable. None of
         the Leased Premises, nor any portion thereof, is within a "special
         assessment district" and, to the knowledge of Seller or Shareholder, no

         Seller. There are no laws, rules, regulations or ordinances or
         modifications with respect to zoning or land use in effect or, to the
         knowledge of Seller or Shareholder, proposed, which restrict or
         prevent, or will restrict or prevent, the use of the Purchased Assets
         or Leased Premises in substantially the same manner as such Purchased
         Assets or Leased Premises, as the case may be, are currently being used
         by Seller ("Buyer's Intended Use"); and, further, none of the parcels
         comprising the Leased Premises constitutes any non-conforming use.

                  (d) Adverse Restrictions and Rights. There are no existing
         easements, rights-of-way, or restrictions other than existing zoning
         and government regulations affecting the Leased Premises which could
         adversely affect or prohibit the use of any of the Leased Premises for
         Buyer's Intended Use.

                  (e) Third-Party Rights/Encumbrances. No party other than Buyer
         has any right or option to acquire the Purchased Assets or any portion
         thereof.

                  (f) Environmental Compliance. Except as set forth in Schedule
         5.10(f) hereto, (i) none of the real property owned, leased, managed,

or with respect to a sale, encumbrance or transfer of any stock of Seller.

         5.20     Accounts Receivable.

                  (a) All Accounts Receivable of Seller that are reflected on
         the Balance Sheet or the Interim Balance Sheet (except to the extent of
         collections thereof) represent, and all Accounts Receivable that will
         be reflected on the accounting records of Seller as of June 30, 1997,
         will represent, valid obligations in favor of Seller arising from sales
         actually made by the Seller in the ordinary course of the Business.
         Unless paid prior to the Closing Date, the Accounts Receivable (other
         than those of the Special Account Debtors, as to which no
         representation or warranty as to collectibility is given) (the "Other
         Accounts Receivables") will be as of the Closing Date collectible net
         of the reserves with respect to the Other Accounts Receivables shown on
         the Closing Balance Sheet. Subject to such reserves, each of the Other
         Accounts Receivable will be collected in full, without any set-off, in
         the ordinary course. Except as provided in Schedule 5.20(a), there is
         no contest, claim, or right of set-off, or, to the best of Seller's and
         Shareholder's knowledge, any threatened contest, claim or right of
         set-off, or circumstances that with notice, the lapse of time or both,
         could result in such a contest, claim or right of set-off (other than
         with respect to returns of merchandise in the ordinary course of the
         Business), with respect to any Account Receivable or under any contract
         with any obligor of an Account Receivable.

                  (b) Schedule 5.20(b) contains a complete and accurate list of
         all Accounts Receivable of Seller as of June 30, 1997, which list sets
         forth the aging of such Accounts Receivable and describes any
         collateral that secures payment of any Accounts Receivable.

                  (c) Except as provided in Schedule 5.20(c), no account debtor
         has withheld payment or threatened to withhold payment of any Account
         Receivable and, to the best of Seller's and Shareholder's knowledge,
         none of Seller's account debtors is insolvent or has filed or had filed
         against it a petition in bankruptcy or similar petition and, to the
         best of Seller's and Shareholder's knowledge, there are no
         circumstances that could lead to such insolvency or bankruptcy filing
         or similar petition.

         5.21 Inventory. All Inventory of Seller, whether or not reflected in
the Balance Sheet or the Interim Balance Sheet consists of a quality and
quantity usable and salable in the ordinary course of the Business, except for
obsolete items and items of below-standard quality, all of which have been
written off or written down to net realizable value in the Balance Sheet, the
Interim Balance Sheet and on the accounting records of Seller as of June 30,
1997, as the case may be. All Inventory not written off has been valued on
Seller's books and records at Seller's net cost, which does not exceed net
realizable value on a first in, first out basis. The quantities of each item of
the Inventory are reasonable with respect to the needs of the Business.


                                       26





         5.22 No Undisclosed Liabilities. Except for the Assumed Liabilities,
Seller has no liabilities or obligations of any nature (whether known or unknown
and whether absolute, accrued, contingent, or otherwise) for which Buyer will or
could be liable.

         5.23 Solvency. Seller is not now insolvent, and will not be rendered
insolvent by any of the transactions contemplated by this Agreement. In
addition, immediately after giving effect to the consummation of the
transactions contemplated by this Agreement (a) Seller will be able to pay its
debts as they become due, (b) the property of Seller does not and will not
constitute unreasonably small capital, and Seller will not have unreasonably
small capital and will not have insufficient capital with which to conduct its
present or proposed business, and (c) taking into account all pending and
threatened litigation, final judgments against Seller in actions for money
damages are not reasonably anticipated to be rendered at a time when, or in
amounts such that, Seller will be unable to satisfy any such judgments promptly
in accordance with their terms (taking into account the maximum probable amount
of such judgments in any such actions and the earliest reasonable time at which
such judgments might be rendered) as well as all other obligations of Seller.
The cash available to Seller, after taking into account all other anticipated
uses of the cash of Seller, will be sufficient to pay all such judgments
promptly in accordance with their terms. For purposes of this Section,
"insolvent" means that the sum of the present fair saleable value of Seller's
assets does not and will not exceed its debts and other probable liabilities,
and the term "debts" includes any legal liability of Seller, whether matured or
unmatured, liquid or unliquidated, absolute, fixed or contingent, disputed or
undisputed or secured or unsecured.

         5.24 No Misrepresentations. The representations, warranties and
statements made by Seller, Shareholder and Mrs. Helzer in or pursuant to this
Agreement and the Exhibits and Schedules hereto are true, complete and correct
in all respects and do not contain any untrue statement of a material fact or
omit to state any material fact necessary to make any such representation,
warranty or statement, under the circumstances in which it was made, not
misleading. Seller and Shareholder have disclosed to Buyer all material events,
conditions or facts known to either or both of them that affect the condition
(financial or otherwise), business or prospects of Seller. None of the
information supplied or to be supplied by Seller or Shareholder for inclusion in

Exchange Act of 1934 (the "Exchange Act") in connection with Seller,
Shareholder, the Acquired Business or the transactions contemplated by this
Agreement (for purposes of this Section and Section 8.11, the "Registration
Statement"), or any other document to be filed with any regulatory authority in
connection with Seller, Shareholder, the Acquired Business or the transactions
contemplated hereby will, when any such Registration Statement becomes effective
or any such other document is filed, be false or misleading with respect to any
material fact, or omit to state any material fact necessary in order to make the
statements therein not misleading.

11. Covenant Not to Compete. Seller and Shareholder hereby, jointly and
severally, agree as follows:

         11.1 Noncompetition. For a period of five (5) years following the
Effective Time, neither Seller nor Shareholder, nor any person or entity
directly or indirectly owning, owned by, controlling, controlled by or under
common ownership or control with ("Affiliates") Seller or Shareholder, shall,
directly or indirectly, on its, his or their own behalf or on behalf of any
competitor of Buyer: (a) engage (whether as owner, partner, stockholder, joint
venturer, manager, employee, investor or otherwise) in the sale, at wholesale or
retail, of any roofing materials or supplies and/or building products or
supplies (the "Restricted Business") in the counties of the State of Texas, the
States of Colorado, Indiana, Iowa and Virginia and in all other areas in which
Buyer is transacting business at June 30, 1997 or has transacted business in the
past two years (collectively, the "Market"); (b) affiliate with, or own or have
a proprietary interest of any kind in, any business or firm that owns, manages
or operates a business that sells at wholesale or retail any roofing materials
or supplies and/or building products or supplies anywhere within the Market; or
(c) alone or acting with others, employ or attempt to employ or solicit for any
employment competitive with Buyer, any of Buyer's employees who worked for
Seller prior to the Closing, or alone or acting with others, influence or seek
to influence any employee to leave Buyer's employment. Seller and Shareholder
also covenant, 


                                       32





jointly and severally, that at no time shall any or either of them disparage
Buyer, any of its affiliated entities, or any of the directors or officers of
Buyer or any of its affiliated entities.

         The parties acknowledge that Shareholder's son is in the roofing
contracting business in Texas, Indiana and Virginia, and that Shareholder's
providing of advice to his son with respect to such business will not be deemed
to be a breach of this Section provided that in providing such advice,
Shareholder is not directly or indirectly engaging in the Restricted Business
anywhere within the Market during the five year period described above.

         11.2 Payment for Covenants. As additional consideration to Shareholder
for his covenants under Section 11.1. Buyer shall pay at the Closing One Hundred
Dollars ($100.00) to Shareholder.

         11.3 Remedies: Curtailment. Seller and Shareholder each agrees that a
breach or violation of the covenants in Section 11.1 by Seller or Shareholder
shall entitle Buyer, as a matter of right, to an injunction issued by any court
of competent jurisdiction, restraining any further or continued breach or
violation of such covenants. Such right to an injunction shall be cumulative and
in addition to, and not in lieu of, any other remedies to which Buyer may be
entitled. Further, during any period in which Seller or Shareholder is in breach
of any of such covenants, the time period of such covenant shall be extended for
an amount of time that Seller or Shareholder is in breach hereof In the event of
a breach by Seller or Shareholder of the covenants under Section 11.1, without
limiting Buyer's remedies with respect to such breach, including, without
limitation, equitable remedies, Buyer shall not be required to make, and Seller
or its designee shall have no right to receive, any further payments under
Section 2.4(a), (h) or (c).

         The covenants contained in Section 11.1 will be construed as ancillary
to and independent of any other provision of this Agreement, and the existence
of any claim or cause of action of Seller or Shareholder against the Buyer or
any officer, director, or shareholder of Buyer, whether predicated on this
Agreement or otherwise, shall not constitute a defense to the enforcement by
Buyer of the covenants contained in Section 11.1.

         The parties to this Agreement agree that the limitations contained in
Section 11.1 with respect to geographic area, duration and scope of activity are
reasonable. However, if any court shall determine that the geographic area,
duration or scope of activity of any restriction contained in Section 11.1 is
unenforceable, it is the intention of the parties that such restrictive covenant
set forth herein shall not thereby be terminated but shall be deemed amended to
the extent required to render it valid and enforceable.

         12.1 BUYER'S RIGHT TO INDEMNIFICATION. SELLER SHAREHOLDER AND MRS.

         13.2 Limitation on Right to Terminate. A party shall not be permitted
to exercise any right of termination pursuant to Section 13.1(b) above if the
event giving rise to the termination right shall be due to the material and
willful failure of the party seeking to terminate this Agreement to perform


                                       37





or observe any of the covenants or agreements set forth herein to be performed

or to any party to this Agreement (except pursuant to this Section 13 and to
Sections 14.3. 14.4. 14.5 and 14.6, which shall survive such termination). In
any such event, except as otherwise expressly provided in this Agreement, all
parties hereto shall thereupon be relieved of all further obligations to each
other hereunder.

         If Seller or Shareholder, on the one hand, or Buyer, on the other hand,
fails to perform any of its or his obligations under this Agreement, then the
other party or parties may elect (a) to terminate this Agreement whereupon all
parties hereto shall be released from any further obligations hereunder, (b) to
seek specific performance of the other party's or parties' obligations
hereunder, or (c) to pursue any and all other remedies available at law or in
equity.

hold harmless Buyer against all claims for fees, commissions and costs of any

         14.8 Assignment; and No Third Party Beneficiaries. This Agreement and
all of the provisions hereof shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and permitted assigns, but
neither this Agreement nor any of the rights, interests or obligations hereunder
shall be assigned or delegated by any of Seller, Shareholder or Buyer without
the prior written consent of the other party or parties; provided, however, that
notwithstanding the foregoing, Buyer may assign this Agreement to any related or
affiliated entity of Buyer or any lender to Buyer. Any assignment or delegation
made in violation of this Agreement shall be null and void. This Agreement is
not intended to confer upon any person (including, without limitation,
employees, customers or suppliers of Seller or Buyer) other than the parties
hereto and any permitted assignee, any rights or remedies hereunder. Nothing in
this Agreement shall be construed to imply any admission of liability or
obligation to any person except the parties to this Agreement.

Exhibits and Schedules hereto or expressly contemplated hereby contain the

         14.10 Exhibits and Schedules. All Exhibits and Schedules to this
Agreement are incorporated herein by reference and made a part hereof.

         14.11 Governing Law. This Agreement shall be governed by, and construed
and interpreted in accordance with, the substantive laws of the State of New
York without giving effect to any conflict-of-laws rule or principle that might
result in the application of the laws of another jurisdiction.

         14.12 Jurisdiction and Venue. Any action or proceeding seeking to
enforce any provision of, or based on any right arising out of, this Agreement
may be brought against any of the parties in the courts of the State of New
York, or, if it has or can acquire jurisdiction, in the United States District
Court for the Southern District of New York, or the Middle District of Florida,
and each of the parties consents to the jurisdiction of such courts (and of the
appropriate appellate courts) in any such action or proceeding and waives any
objection to venue therein. If neither the United States District Court for the
Southern District of New York nor the United States District Court for the
Middle District of Florida has or can acquire jurisdiction, then any action or
proceeding seeking to enforce any provision of, or based on any right arising
out of, this Agreement, shall be resolved by binding arbitration before a panel
of three neutral arbitrators in Atlanta, Georgia, or such other mutually agreed
venue under the rules of the American Arbitration Association.

         14.13 Survival of Representations, Warranties, Covenants and
Agreements. All representations, warranties, covenants and agreements made by
the parties hereto in this Agreement or in any certificate or other document
delivered pursuant hereto shall survive the execution of this Agreement and the
Closing.

         14.14 Headings. The descriptive headings of the Sections and
Subsections hereof are inserted for convenience only and do not constitute a
substantive portion of this Agreement.

         14.15 Invalidity. In the event that any provision of this Agreement is
determined to be invalid or unenforceable, such invalidity or unenforceability
shall not affect the validity or enforceability of any other provision of this
Agreement.

         14.16 Waiver. The waiver by any party hereto of any breach, default,
misrepresentation or breach of warranty or covenant hereunder must be in writing
and shall not be deemed to extend to any prior or subsequent breach, default,
misrepresentation or breach of warranty or covenant hereunder and shall not
affect in any way any rights arising by virtue of any such prior or subsequent
occurrence.


                                       41





         14.17 Certain Consents. In the event any of the Leases and Contracts
(individually, a "Lease" or a "Contract") requires consent to its assignment and
such consent is not obtained prior to the Closing, and Buyer agrees in writing
to proceed with the Closing despite the absence of such consent, then until such
consent has been obtained or the applicable Lease or Contract terminates, the
Lease or Contract shall not be deemed assigned to Buyer but instead Buyer shall
be deemed to be Seller's subcontractor or the parties shall make such other
arrangements as necessary to assure Buyer the benefits of the Lease or Contract.
In that event, Buyer shall perform all obligations of Seller under the
applicable Lease or Contract (except any obligations arising out of a default
prior to the Closing Date or event prior to the Closing Date which with notice,
lapse of time or both would constitute such a default), and Buyer shall be
entitled to all benefits from such Lease or Contract. Seller, Shareholder, and
Mrs. Helzer, jointly and severally, shall indemnify Buyer with respect to all
Losses of Buyer resulting from or arising out of the failure of Seller to obtain
such consent.
