described in Section 351(a) of the Code. HDA and Holdings agree that the
consummation of the HDA Stock Contribution will occur on the same day as the
Closing Date.

          1.3.  Post-Closing Purchase Price Adjustment.
                -------------------------------------- 

          (a)   Determination of Earnings.  The Selling Parties will prepare at
                -------------------------                                      
the expense of Truck (i) a combined income statement of the Companies for the
period from January 1, 1998 through the Closing (the "Closing Income Statement")
and (ii) a balance sheet dated the Closing Date (as defined) (the "Closing
Balance Sheet" and together with the Closing Income Statement, the "Closing
Financial Statements"), prepared in accordance with generally accepted
accounting principles ("GAAP") applied in the same manner as the Balance Sheet
and the 1997 Income Statement (as defined in Section 3.8(a)).  The Selling
Parties will deliver such Closing Financial Statements to HDA as soon as
possible but in any event within 45 days after the Closing.  The Closing
Financial Statements shall be audited by Ernst & Young at the expense of HDA.

          (b)   Closing Financial Statements Notice.
                ----------------------------------- 

                (i)    Within 30 days of the receipt of such Closing Financial
     Statements, HDA will deliver to the Existing Shareholders a written notice
     certifying that either (x) it agrees with such Closing Financial
     Statements, or (y) it disagrees with such Closing Financial Statements, in
     which case it will also provide therewith a reasonably detailed written
     report stating the basis for disagreement with the Closing Financial
     Statements (the "Closing Financial Statements Notice").  The Companies
     shall provide reasonable access to their respective accountants' work
     papers, personnel and to such historical financial information as HDA shall
     reasonably request in order to review such Closing Financial Statements.


                (ii)   If the Closing Financial Statements Notice is not timely
     given as described in Section 1.3(b)(i), the Closing Financial Statements
     shall be final, binding and conclusive upon the Parties.  If the Existing
     Shareholders disagree with the Closing Financial Statements Notice as
     described in Section 1.3(b)(i)(y), and if the disagreement is not resolved
     by mutual agreement among the Parties within 30 days following delivery of
     the Closing Financial Statements Notice, such dispute will be resolved by a
     "Big 5" accounting firm ("BFAF"), other than Ernst & Young or Coopers &
     Lybrand, selected by HDA and the Selling Parties.  The costs of resolving
     such a dispute shall be borne equally by HDA and the Existing Shareholders.

                (iii)  Upon appointment of a BFAF, such BFAF in consultation
     with the Parties shall establish a schedule for resolution of the dispute
     which is reasonably calculated to result in a resolution as expeditiously
     as practicable, and in any event, no later than six months after the
     Closing Date. In resolving such dispute, the BFAF shall revise the Closing
     Financial Statements only with respect to the issues raised in the Closing
     Financial Statements Notice and only to the extent necessary to make it
     conform to the practices, procedures and methods described in Section
     1.3(a) above.

          (c)   Post-Closing Adjustment.  After a final resolution by the 
                -----------------------   
BFAF of such 

                                       3

 
disagreements as may arise out of the review of the Closing Financial Statements
in accordance with Section 1.3(b) above, and an appropriate adjustment to the
Closing Financial Statements to reflect such resolution, or if Section
1.3(b)(i)(x) or the first sentence of Section 1.3(b)(ii) applies, the actual
year to date undistributed earnings of Truck will be determined, and the actual
Purchase Price (the "Cash Purchase Price") will be calculated based on such, and
to the extent that the Estimated Cash Purchase Price was less than the Cash
Purchase Price, the difference and interest thereon due to the Selling Parties
will promptly be paid to them by HDA. Similarly, to the extent the Estimated
Cash Purchase Price was more than the Cash Purchase Price, the excess will be
promptly returned by the Selling Parties to HDA. Any amounts payable pursuant to
this paragraph shall bear interest from the Closing Date through the date of
payment at an annual rate equal to the prime rate as reported in The Wall Street
Journal on the Closing Date.

          1.4.  Transfer of Assets. Upon the terms and subject to the
                ------------------
conditions set forth herein, at the Closing, DHP will sell to HDA, and HDA will
purchase from DHP, the Assets, free and clear of all encumbrances other than
Permitted Encumbrances (as defined herein).

          1.5.  Assumption of Liabilities. Upon the terms and subject to the
                -------------------------
conditions contained herein, at the Closing, HDA shall assume all obligations
and liabilities accruing, arising out of, or relating to events or occurrences
happening after the Closing Date under, and only under, the Assumed Contracts
(as defined) listed on Schedule 3.15, but not including any obligation or
liability of DHP for any breach of any Contract (as defined) occurring on or
prior to the Closing Date (together with the liabilities assumed pursuant to the
Assumed Contracts, the "Assumed Liabilities").

          1.6.  Excluded Liabilities. Notwithstanding any other provision of
                --------------------
this Agreement, except for the Assumed Liabilities expressly specified in
Section 1.4 hereof, HDA shall not assume, or otherwise be responsible for, any
of DHP's liabilities or obligations, whether actual or contingent, matured or
unmatured, liquidated or unliquidated, known or unknown, or related or unrelated
to the Business or the Assets, whether arising out of occurrences prior to, at
or after the date hereof (collectively, "Excluded Liabilities"), which Excluded
Liabilities include, without limitation:

          (a)   Any liability or obligation to or in respect of any employees
or former employees of DHP including without limitation (i) any employment
agreement, whether or not written, between DHP and any person, (ii) any

                         THE SELLING PARTIES AND TURNER

          The Selling Parties jointly and severally, and in certain instances
where indicated, Turner severally, represent and warrant to Holdings and HDA as
follows, except as set forth in a disclosure schedule ("Schedule") attached
hereto and made a part hereof, the number of each Schedule corresponding to the
Section number to which it refers:

          3.1.  Corporate Organization and Standing.  Schedule 3.1 hereto is a
                -----------------------------------
complete and correct list setting forth for each of the Companies (i) the name
of each entity, the jurisdiction of its incorporation or other organization, and
each jurisdiction in which it is qualified to do business as a foreign
corporation. Each of the Companies is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation and has all requisite corporate power and authority to own or
lease its properties and to carry on its business as presently conducted. Each
of the Companies has delivered to HDA or its representatives complete and
correct copies of its Articles of Incorporation and Bylaws (or other charter
documents) and all amendments thereto. Each of the Companies is duly qualified
to do business as a foreign corporation and is in good standing in each
jurisdiction in which the nature of the business as now being conducted by it or
the property owned or leased by it makes such qualification necessary, except
where the failure to qualify would not have a material adverse effect (as
defined) on the Companies taken as a whole.

                                       6

 
          3.2.  Capitalization of Company.  The authorized capital stock of
                -------------------------
Truck consists of 10,000 shares of common stock, no par value per share ("Truck
Common Stock"). As of the date of this Agreement, 1,069 shares of Truck Common
Stock are outstanding, all of which shares have been duly authorized, validly
issued and are fully paid and non-assessable and are owned in the aggregate by
Pope and Turner (the "Shares"). There are (i) no preemptive or similar rights on
the part of any holder of any class of securities of Truck, and (ii) no options,
warrants, conversion or other rights, agreements or commitments of any kind
obligating Truck, contingently or otherwise, to issue, sell or otherwise cause
to be outstanding any shares of its capital stock of any class or any securities
convertible into or exchangeable for any such shares.

          3.3.  Authorization.  This Agreement, the Ancillary Agreements (as
                -------------
defined), and the transactions contemplated hereby and thereby have been duly
authorized, executed and delivered by each of the Selling Parties that is a
party to each such agreement, and are the legal, valid and binding obligations
of each of the Selling Parties that is a party thereto, enforceable against it,
him or her in accordance with their terms, except as enforcement may be limited
by equitable principles limiting the right to obtain specific performance or
other equitable remedies, or by applicable bankruptcy or insolvency laws and
related decisions affecting creditors' rights generally.

          3.4.  Title to Shares.  Pope has, and at Closing will have, good and
                ---------------
valid title to the Shares owned by him, free and clear of any claims, liens,
security interests, options, charges, restrictions and interests of others
whatsoever. Upon delivery to HDA at the Closing of certificates representing the
Shares owned by Pope, duly endorsed by him for transfer to HDA, HDA will obtain
good and valid title to such Shares, free and clear of any claims, liens,
security interests, options, charges, restrictions and interests of others
whatsoever, except for any restrictions created by HDA. There are no voting
trusts, proxies, or other agreements or understandings to which Pope or Truck is
a party with respect to the voting, dividend right or disposition of any of the
Shares. Pope has no obligation, absolute or contingent, to any other person or
entity to issue, sell or otherwise dispose of any capital stock of Truck or to
effect any merger, consolidation, reorganization or other business combination
of any Company or to enter into any agreement with respect thereto.

          3.5.  No Conflict or Violation.  Neither the execution and delivery of
                ------------------------
this Agreement or the Ancillary Agreements by the Popes and the Companies nor
the consummation by the Popes and the Companies of the transactions contemplated
hereby or thereby will (i) violate, conflict with or result in or constitute a
default under or result in the termination or the acceleration of, or the
creation in any party of any right (whether or not with notice or lapse of time
or both) to declare a default, accelerate, terminate or cancel any indenture,
contract, lease, sublease, loan agreement, note or other obligation or liability
("Contractual Obligation") to which the Popes or the Companies are a party or by
which any of them are bound or to which any of their assets is subject or result
in the creation of any lien or encumbrance upon any of said assets, (ii)
violate, conflict with or result in a breach of or constitute a default under
any provision of the Articles of Incorporation or Bylaws (or other
organizational documents) of any Company, (iii) violate, conflict with or result

                --------------------------                                   
there are no leases, subleases, licenses, occupancy agreements, options, rights,
concessions or other agreements or arrangements, written or oral, granting to
any person the right to purchase, use or occupy any Facility or any Real
Property or any portion thereof, or interest in any such Facility or Real
Property.

          (c)   Facility Leases and Leased Real Property.  With respect to each
                ----------------------------------------                       
Facility lease, the Companies have an unencumbered interest in the leasehold
estate, other than Permitted Encumbrances.  The Companies enjoy peaceful and
undisturbed possession of all Leased Real Property.

          (d)   Certificate of Occupancy.  All Facilities have received all
                ------------------------

occupancy of the Facilities) required in connection with the operation thereof
in order to avoid a material adverse effect on the Companies and are and have
been operated and maintained in all material respects in accordance with
applicable material regulations.

          (e)   Utilities.  All Facilities are supplied with utilities
                ---------                                             
(including, without limitation, water, sewage, disposal, electricity, gas and
telephone) and other services necessary for the operation of such Facilities as
currently operated.

          (f)   Improvements, Fixtures and Equipment.  The improvements
                ------------------------------------

conformity in all material respects with all applicable material regulations.

          (g)   No Special Assessment.  No Company has received notice from any
                ---------------------

Assets, free and clear of any encumbrances, except for minor liens which in the
aggregate are not substantial in amount, do not materially detract from the
value or transferability of the Assets subject thereto taken as a whole or
interfere in any material respect with the present use and have not arisen other
than in the ordinary course of business ("Permitted Encumbrances"). All tangible
assets and properties which are part of the Assets are in good operating
condition and repair, ordinary wear and tear excepted, and are usable in the
ordinary course of business and conform in all material respects to all
applicable material regulations (including Environmental Laws (as defined
herein)) relating to their use and operation.

          3.8.  Financial Statements.
                -------------------- 

          (a)   The audited balance sheets of each of the Companies dated
December 31, 1997, 1996 and 1995, respectively (the "Balance Sheets," the "1996
Balance Sheets" and the "1995 Balance Sheets," respectively), were prepared in
accordance with GAAP consistently applied and fairly present in all material
respects the financial condition of Truck and DHP as of their respective dates.
As of the dates of the respective Balance Sheets, none of the Companies had any
liabilities of any nature, whether absolute, accrued, asserted or unasserted or
contingent or whether due or to become due, which should have been recorded or
reserved for on the Balance Sheets in accordance with GAAP and were not so
recorded or reserved.  The Companies have not incurred any material liabilities
since December 31, 1997 other than in the ordinary course of business.

          (b)   The audited statements of operations, statements of changes in
shareholder's equity and statements of cash flows of each of the Companies for
the fiscal years ended December 31, 1997 (the "1997 Income Statement"), 1996 and
1995, respectively, were prepared in accordance with GAAP consistently applied
and fairly present in all material respects the results of operations, changes
in shareholder's equity and cash flows of the Companies for each such period.

          (c)   The unaudited balance sheet, statements of operations,
statements of changes in shareholder's equity and statements of cash flows of
each of the Companies at and for the seven months ended July 31, 1998, fairly

shareholder's equity and cash flows of the Companies for each such period.

          (d)   Copies of the financial statements described in Section 3.8(a)
and (b) have been provided to HDA or its representatives.

          3.9.  Books and Records.  Each of the Companies has made and kept and
                -----------------
given HDA and its representatives access to books and records and accounts,
which, in reasonable detail, accurately and fairly reflect the activities of
each of the Companies recorded therein. The copies of the stock book records of
each of the Companies are true, correct and complete, and accurately reflect all
transactions effected in each Company's stock through and including the date
hereof.

                                       9

 
          3.10. Litigation.  There is no claim, action, suit, proceeding, or
                ----------
investigation pending or, to the best knowledge of the Companies, threatened
against any of the Companies or the directors, officers, agents or employees of
any of the Companies (in their capacity as such), or any properties or rights of
any of the Companies. There are no orders, writs, injunctions or decrees
currently in force against any of the Companies or the directors, officers,
agents or employees of any of the Companies (in their capacity as such) with
respect to the conduct of any Company's business.

          3.11. Licenses and Permits; Compliance with Laws.  Schedule 3.11 sets
                ------------------------------------------
forth a complete list of all licenses, franchises, permits, approvals and other
governmental authorizations (collectively, "Licenses and Permits") held by each
of the Companies. Each of the Companies owns, holds or possesses all Licenses
and Permits necessary to entitle it to use its corporate name, to own or lease,
operate and use its assets and properties and to carry on and conduct its
business and operations as presently conducted except where the failure to own,
hold or possess any Licenses and Permits would not have a material adverse
effect on the Companies. No Company is in violation of or default under any
Licenses or Permits or any judgment, order, writ, injunction or decree of any
court or administrative agency issued against it or any law, ordinance, rule or
regulation applicable to it where such violation would have a material adverse
effect on the Companies. Each Company's conduct of its business has been and is
in compliance in all material respects with all material applicable laws,
statutes, ordinances and regulations. No Company has received any notice
asserting a failure to comply with any law, statute, ordinance, regulation, rule
or order of any foreign, federal, state or local government or any other
governmental department or agency that has not been cured prior to the date
hereof. Any such notice received since January 1, 1995 has been provided to HDA
or its representatives.

          3.12. Tax Matters.
                ----------- 

          (a)   For purposes of this Agreement, (i) "Tax" means any federal,
state, local or foreign income, gross receipts, license, payroll, employment,
excise, severance, stamp, occupation, premium, windfall profits, environmental,
customs duties, capital stock, franchise, profits, withholding, social security,
unemployment, disability, real property, personal property, sales, use,
transfer, registration, value added, alternative or add-on minimum, estimated,
or other tax of any kind whatsoever, including any interest, penalty, or
addition thereto, whether disputed or not, and (ii) "Tax Return" means any
return, declaration, report, claim for refund, or information return or
statement relating to Taxes, including any schedule or attachment thereto, and
including any amendment thereof.

          (b)   Each Company has timely filed, or caused to be timely filed, all
Tax Returns that it was required to file.  All such Tax Returns were correct and
complete in all material respects.  All Taxes owed by each Company (whether or
not shown on any Tax Return) that are due and payable have been paid.  No
Company currently is the beneficiary of any extension of time within which to
file any Tax Return.  Neither Company has received written notice of any claim
by an authority in a jurisdiction where such Company does not file Tax Returns
that such Company is subject to taxation by that jurisdiction.  There are no
liens on any 

                                       10

 
of the assets of any Company that arose in connection with any failure (or
alleged failure) to pay any Tax.

          (c)   Each Company has withheld and paid all Taxes required to have
been withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, stockholder, or other third party.

          (d)   There is no dispute or claim concerning any Tax Liability of any
Company either (i) claimed or raised by any authority in writing or (ii) of
which any Existing Shareholder or any Company has knowledge.  To the knowledge
of each Company and each Existing Shareholder, no audit or examination of any
Tax Return is currently in progress, and no Company has received notice of any
proposed audit or examination.  Each Company has furnished to HDA or its
representatives correct and complete copies of all federal income Tax Returns,
examination reports, and statements of deficiencies assessed against or agreed
to by any Company with respect to years ended on or after December 31, 1991.  No
Company has waived any statute of limitations in respect of Taxes or agreed to
any extension of time with respect to a Tax assessment or deficiency.

          (e)   No Company has filed a consent under Section 341(f) of the Code
concerning collapsible corporations (or any comparable state income tax
provision).  No Corporation has made any payments, is obligated to make any
payments, or is a party to any agreement that under certain circumstances could
obligate it to make any payments that will not be deductible under Section 280G
of the Code.  No Company is a party to any Tax allocation, sharing or indemnity
agreement.  No Company (i) has been a member of an affiliated group of
corporations filing a consolidated federal income Tax Return or (ii) has any
liability for the Taxes of any person under Reg. Sec. 1.1502-6 (or any similar
provision of state, local or foreign law), as a transferee or successor, by
contract, or otherwise.

          (f)   The unpaid Taxes of each Company as of the date of the most
recent Balance Sheets did not exceed the reserve for Tax Liability (rather than
any reserve for deferred Taxes established to reflect timing differences between
book and Tax income) set forth on the face of the most recent Balance Sheets.
Each Company has made provision, in conformity with GAAP consistently applied,
on the Balance Sheets and the interim financial statements for the payment of
all Taxes which may subsequently become due with respect to the respective
periods covered in the Balance Sheets.

          (g)   The Companies are each an "S Corporation."  Truck and DHP have
each been a validly electing S corporation within the meaning of Sections 1361
and 1362 of the Code (and any analogous provisions of state and local law) at
all times since January 1, 1997 and January 25, 1995, respectively, and each
will be an S corporation up to and including the Closing Date.  No federal,
state, local or foreign income taxes will be payable by the Companies with
respect to the taxable year beginning on January 1, 1998 and ending on the day
immediately preceding the Closing Date

                                       11

 
          3.13. Brokers, Finders.  No Company nor any Existing Shareholder has
                ----------------
retained any broker or finder other than SunTrust Equitable Securities in
connection with the transactions contemplated herein, and is not obligated and
has not agreed to pay any brokerage or finder's commission, fee or similar
compensation.

          3.14. Absence of Certain Changes.
                -------------------------- 

          (a)   Since December 31, 1997, each Company has conducted its business
in the ordinary course, has not done or permitted to be done anything described
in Sections 5.6(a) through (r), and there has not occurred with respect to any
Company:

                (i )   any material adverse effect on the business, operations,
     assets, results of operations or financial condition of the Companies,
     taken as a whole ("Material Adverse Effect");

                (ii)   any revaluation of assets, including, without limitation,
     writing down the value of inventory or writing off notes or accounts
     receivable, other than write-offs of uncollectible notes and accounts
     receivable and write-downs of obsolete, slow moving or unsaleable inventory
     in the ordinary course of business consistent with past practice;

                (iii)  any payment, discharge or satisfaction of any liabilities
     or obligations, other than in the ordinary course of business;

                (iv)   any incurrence of liabilities, except liabilities
     incurred in the ordinary course of business, or increase or change in any
     assumptions underlying or methods of calculating, any doubtful account
     contingency or other reserves;

                (v)    any capital expenditure exceeding $5,000, the execution
     of any lease or the incurrence of any obligation to make any capital
     expenditure or execute any lease other than in the ordinary course of
     business;

                (vi)   the failure to pay or satisfy when due any liability,
     except where the failure would not have a material adverse effect on the
     assets or the business;

                (vii)  any assets (whether real, personal or mixed, tangible or
     intangible) becoming subject to any mortgage, pledge, lien, security
     interest, encumbrance, restriction or charge of any kind, except in the
     ordinary course of business;

                (viii) the failure of the Companies to use reasonable efforts
     consistent with past practice to preserve for HDA the assets, the business
     and the goodwill of each of the Company's suppliers, customers,
     distributors and others having business relations with it;

                                       12

 
                (ix)   the disposition or lapsing of any Proprietary Rights (as

                ------------------
complete and correct list of all the Material Contracts to which any Company, or

          (b)   all leases or other agreements under which any Company is a

                                       14

 
          (h)   any contract with the United States, state or local government
or any agency or department thereof, involving expenditures or liabilities in
excess of $10,000; or

          (i)   excluding purchase orders issued or received in the ordinary
course of business, any contract or agreement providing for the receipt or

after the date of this Agreement, including, without limitation, agreements
calling for penalties or payments upon voluntary termination or withdrawal by
any Company.

The Companies have furnished or will furnish to HDA or its representatives true
and correct copies of all Material Contracts prior to the Closing, including all
amendments and supplements thereto.

          3.16. Proprietary Rights.
                ------------------ 

          (a)   The Companies have no patents, trademarks (whether registered or
unregistered), service marks, trade names, service names, brand names, logos and
copyrights (collectively, the "Proprietary Rights"), except to the extent their
names constitute unregistered trademarks ("Names").  The only Proprietary Rights
used by the Companies in connection with their respective businesses are the
Names.

          (b)   No Company has any obligation to compensate any person for the
use of any such Proprietary Rights nor has any Company granted to any person any
license, option or other rights to use in any manner any of its Proprietary
Rights, whether requiring the payment of royalties or not.

          (c)   The Companies individually or collectively own or have a valid
right to use each of the Proprietary Rights, and the Proprietary Rights will not
cease to be valid rights of any Company by reason of the execution, delivery and
performance of this Agreement, the Ancillary Agreements or the consummation of
the transactions contemplated hereby and thereby.  No Company has received any
notice of invalidity or infringement of any rights of others with respect to any
Proprietary Rights.  No other person (i) has notified any Company that it is
claiming any ownership of or right to use such Proprietary Rights, or (ii) to
the best knowledge of the Companies, is infringing upon any such Proprietary
Rights in any way.  To the knowledge of the Companies, any Company's use of any
Proprietary Rights does not and will not conflict with, infringe upon or
otherwise violate the valid rights of any third party in or to such Proprietary
Rights, and no Action has been instituted against or notices received by any
Company alleging that a Company's use of the Proprietary Rights infringes upon
or otherwise violates any rights of a third party in or to such Proprietary
Rights.

          3.17. Labor Matters.  No Company is a party to any labor agreement
                -------------
with respect to its employees with any labor organization, union, group or
association. No Company has experienced any attempt by organized labor or its
representatives to make it conform to demands of organized labor relating to its
employees or to enter into a binding agreement with organized labor that would
cover the employees of such Company. There is no labor strike or labor
disturbance pending or, to the best knowledge of any Company, threatened against
a 

                                       15

 
Company, nor is any grievance currently being asserted by any union member, and
no Company has experienced an organized work stoppage, and is not and has not
engaged in any unfair labor practice. Without limiting the foregoing, the
Companies are in compliance with the Immigration Reform and Control Act of 1986
and maintains a current Form I-9, as required by such Act, in the personnel file
of each current employee hired after November 9, 1986.

          3.18. Consents.  Except for the filing required under the Hart-Scott-
                --------
Rodino Antitrust Improvements Act of 1976, as amended (the "H-S-R Act"), no
consent, approval, authorization, order, filing, registration or qualification
(each a "Consent") of or with any court, governmental authority or third person
is required to be made or obtained by any Company in connection with the
execution and delivery of this Agreement, the Ancillary Agreements or the
consummation by the Companies and the Existing Shareholders of the transactions
contemplated herein and therein, which Consent(s), if not obtained, would have a
material adverse effect.

          3.19. Employee Benefit Plans; Employment Agreements.
                --------------------------------------------- 

          (a)   Schedule 3.19 hereto sets forth a complete and correct list of
all (i) employment contracts, employment arrangements and other arrangements
that provide benefits to employees or former employees of any Company and that
are not Plans (as defined below) (collectively, the "Employment Contracts") and
(ii) all "employee welfare benefit plans" or "employee pension benefit plans,"
as such terms are defined in Sections 3(1) and 3(2), respectively, of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), which are
maintained, administered or contributed to by the Companies and cover employees
or former employees of the Companies or under which any Company could incur any
liability (collectively, the "Plans").

          (b)   None of the Plans is subject to Title VII of ERISA.  In the past
six years, no Company has maintained, sponsored, or been required to contribute
to, has withdrawn from (either completely or partially), or has incurred any
unpaid withdrawal liability with respect to, any plan subject to Title VII of
ERISA or the minimum funding requirements of Section 412 of the Code.

          (c)   The Plans have been administered in compliance in all material
respects with their terms and with all filings, reporting, disclosure, and other
requirements of ERISA, the Code and any other applicable law.  The only Plan
which is an "employee pension benefit plan," as such term is defined in Section
3(2) of ERISA is Truck's 401(k) profit sharing plan (the "401(k) Plan").  The
401(k) Plan is and has been for all the years of the Plan the subject of a
favorable determination letter issued by the Internal Revenue Service.  The
Companies have no knowledge of any facts which might adversely affect the
qualifying status of the 401(k) Plan.

          (d)   None of the Companies nor any of their respective employees or
directors, nor, to the knowledge of each Company, any plan fiduciary of any of
the Plans, have engaged in any transaction in violation of Section 406(a) or (b)
of ERISA or any "prohibited transaction" (as defined in Section 4975(c)(1) of
the Code) for which no exemption exists under Section 4975(d) of the Code.

                                       16

 
          (e)   Other than routine claims for benefits made in the ordinary
course of business, there are no pending claims, investigations or causes of
action ("Claims"), and to the best knowledge of any Company, no such Claims are
threatened, against any Plan or fiduciary of any such Plan by any participant,
beneficiary or governmental agency with respect to the qualification or
administration of any such Plan.

          (f)   The Companies have provided to HDA or its representatives a copy
of the Employment Contracts, the Plans, related trust agreements, all amendments
thereto together with the annual report for the last three years (Form 5500,
including Schedule B thereto).  The Companies have provided HDA or its
representatives with true and complete age, salary, service and related data for
employees, former employees and beneficiaries thereof covered under the 401(k)
Plan as of the Closing Date.

          (g)   No entity which is required to be aggregated with any of the
Companies under Sections 414(b), (c), (m) or (o) of the Code, other than any of
the Companies (the "Company ERISA Affiliates") has incurred any liability under
or with respect to any benefit plan, policy or arrangement for the benefit of
its employees or former employees that could become a liability of HDA or any of
the Companies.  Neither HDA nor any Company ERISA Affiliate will incur any
liability under Section 411(d)(3) of the Code for vested accrued benefits
arising from a partial termination of the 401(k) Plan prior to the Closing Date.

          (h)   All amounts required to be contributed to any Plan by any
Company will, as of the Closing Date, have been paid or properly accrued on the
books of each of the Companies. The Companies shall either contribute or accrue
on their respective books the amount of any employer matching contributions or
discretionary contributions (in an amount determined in accordance with each
Company's past practices) to the 401(k) Plan which in the ordinary course of
business would be contributed for or attributable to the period prior to the
Closing Date.

          (i)   None of the assets of the 401(k) Plan is invested in property
constituting employer real property or employer security (within the meaning of
Section 407(d) of ERISA).

          (j)   Neither the execution and delivery of this Agreement, the
Ancillary Agreements nor any of the transactions contemplated herein and
therein, will terminate or modify, or give a third person a right to terminate
or modify, the provisions or terms of any Employment Contract or Plan (including
employment agreements) and will not constitute a stated triggered event under
any Employment Contract or Plan or any other agreement with any person or entity
that will result in any payment or the acceleration of the right to receive any
payment (including parachute payments, severance payments or any similar
payments) that would not be deductible becoming due to any employees of any
Company.

          (k)   No Company or any Plan which is a "welfare benefit plan," as
such term is defined in Section 3(1) of ERISA has any present or future
obligation to provide medical or other welfare benefits to, or to make any
payment to or with respect to medical or other welfare benefits of, any present
or former employee of any Company or any ERISA Subsidiary.

                                       17

 
          (l)   No Company ERISA Affiliate has incurred any liability with
respect to which any Company has incurred or could incur any liability.

          5.2.  Disclosures.  Except as required by law or occurring after the
                -----------
Closing, none of the Parties, without the prior written consent of the other
Parties, will make any press release or any similar public announcement
concerning the transactions contemplated hereby.

          5.3.  Tax Matters.
                ----------- 

          (a)   Truck shall timely prepare and file, or cause to be prepared and
filed, Internal Revenue Service Form 1120S (and any analogous state or local Tax
Returns) in accordance with Section 1362(e) of the Code for the period January
1, 1998 through the day immediately preceding the Closing Date (the "S Short
Year") and Internal Revenue Service Schedules K-1 for the S Short Year.  Truck
shall deliver such Tax Returns to its Existing Shareholders and HDA and its
representatives at least 20 days prior to the filing deadline for such Tax
Returns and obtain the consent of its Existing Shareholders and HDA thereto,
which consent shall not be unreasonably withheld or delayed, prior to the filing
thereof.  The Existing Shareholders of Truck shall timely pay, or cause to be
paid, when due (i) all Taxes relating to the periods covered by such Tax Returns
and (ii) any other Taxes relating to periods ending on or before the Closing
Date and not accrued on the Balance Sheets of Truck.

          (b)   Except as provided in Section 5.7(a), Truck shall prepare or
complete, or cause to be prepared or completed, and timely filed, or cause to be
timely filed, all Tax Returns required to be filed after the Closing Date and,
subject to Section 5.3(c) hereof, shall timely pay, or cause to be timely paid,
when due, all Taxes relating to such Tax Returns in accordance with all
applicable laws and in a manner consistent with the principles set forth in
clause (i) of the next succeeding sentence.  Except as provided in Section
5.3(a), with respect to Tax Returns of Truck not filed prior to the Closing Date
that relate to a taxable period that ends on or prior to or includes the Closing
Date, such Tax Returns shall be prepared or completed by Truck in a manner
consistent with the prior practice of Truck (including elections and accounting
methods and conventions, and as otherwise required by applicable law or
regulation or otherwise agreed to by Truck prior to the filing thereof), and in
a manner that does not distort taxable income (e.g., by accelerating income to a
                                               ----                             
period or periods prior to the Closing Date or deferring deductions to a period
or periods after the Closing Date).  Truck shall deliver such Tax Returns to its
Existing Shareholders and HDA and its representatives at least 20 days prior to
the filing deadline for such Tax Returns and obtain the consent of its Existing
Shareholders and HDA thereto, which consent shall not be unreasonably withheld
or delayed, prior to the filing thereof.

          (c)   Although Truck, as the taxpayer or in connection with filing the
Tax Returns specified in Section 5.3(b) above, may be required to pay Taxes
relating to time periods ending on or before the Closing Date ("Pre-Closing
Taxes"), it is the intention of the Parties that, to the extent such Pre-Closing
Taxes (including any penalties, interest or additions to Tax) were not fully
accrued on the Closing Balance Sheet of Truck, its Existing Shareholders will be
responsible for such Pre-Closing Taxes either by payment of such Pre-Closing
Taxes themselves or pursuant to Section 5.3 hereof.

          (d)   HDA shall promptly notify the Existing Shareholders in writing
upon receipt by HDA or any affiliate of HDA of notice of any pending or
threatened proceeding relating to Taxes for which the Existing Shareholders may
be liable under a Tax proceeding 

                                       27

 
("Tax Proceeding"). The Existing Shareholders shall have the sole right to
control, conduct, and otherwise represent the interests of each Company in any
such Tax Proceeding; provided, however, that without the prior written approval
                     --------  -------
of HDA, which approval shall not be unreasonably withheld or delayed, the
Existing Shareholders shall not agree or consent to compromise or settle any
issue or claim arising in any such Tax Proceeding to the extent that any such
compromise, settlement, consent or agreement could have an adverse effect on HDA
for any period ending after the Closing Date.

          (e)   Neither HDA nor any affiliate of HDA shall, without the prior
written consent of the Existing Shareholders, which consent shall not be
unreasonably withheld or delayed, file or cause to be filed, any amended Tax
Return or claim for Tax refund with respect to Truck relating to Taxes for which
the Existing Shareholders may be liable hereunder.  Promptly after the
reasonable request of the Existing Shareholders, at the sole expense of the
Existing Shareholders, HDA shall, or cause Truck, to file any amended Tax Return
or claim for Tax refund relating to Taxes for which the Existing Shareholders
may be liable hereunder, provided that such amended Tax Returns or claims shall
                         --------                                              
be prepared in a manner consistent with the principles set forth in Section
5.3(b) and, in the reasonable determination of HDA, shall conform to applicable
laws and regulations.  If HDA or any affiliate of HDA shall receive a Tax refund
relating to a period or transaction for which the Existing Shareholders are
liable hereunder, HDA shall, within 30 days after receipt of such Tax refund,
remit such Tax refund (including any interest received on such Tax refund and
net of (i) any Tax cost relating to the receipt of such Tax refund and (ii) any
unreimbursed cost or expense incurred in obtaining such Tax refund), to the
Existing Shareholders.  For purposes of this Section 5.3, the term "Tax refund"
shall include a reduction in Tax or the use of an overpayment as a credit or
other Tax offset, and the receipt of a refund shall be deemed to be realized
upon the earliest to occur of (i) the date on which HDA has actual knowledge
that a payment due to the relevant taxing authority (for which HDA would be
responsible under this Agreement) has been offset by such a refund and (ii) the
receipt of cash.

          (f)   After the date hereof, HDA and Truck shall provide each other
and the Existing Shareholders, with such cooperation and information relating to
Truck as either party reasonably may request in (i) filing any Tax Return,
amended Tax Return or claim for Tax refund, (ii) determining any Tax liability
or a right to a Tax refund, (iii) conducting or defending any proceeding in
respect of Taxes or (iv) effectuating the terms of this Agreement. The Parties
and Truck shall retain all Tax Returns, schedules and work papers, and all
material records and other documents relating thereto, until the expiration of
the statute of limitations (and, to the extent notified by any party, any
extensions thereof) of the taxable years to which such Tax Returns and other
documents relate and until the final determination of any Tax in respect of such
years. Any information obtained under this Section 5.3 shall be kept
confidential, except as may be otherwise necessary in connection with filing any
Tax Return, amended Tax Return, or claim for Tax refund, determining any Tax
liability or right to a Tax refund, or in conducting or defending any
proceedings in respect of Taxes.

                                 ARTICLE VIII.
                    ACTIONS BY THE PARTIES AFTER THE CLOSING

          8.1.  Consents to Assignment.  Anything in this Agreement to the
                ----------------------
contrary notwithstanding, this Agreement shall not constitute an agreement to
assign any lease, contract or license, or any claim or right or any benefit
arising thereunder or resulting therefrom if any attempted assignment thereof,
without the consent of a third party thereto, would constitute a breach thereof
or in any way adversely affect the rights of the Companies thereunder. If such
consent is not obtained, or if an attempted assignment thereof would be
ineffective or would affect the rights thereunder so that HDA would not receive
all such rights. The Companies will cooperate with HDA, in all reasonable
respects, to provide to HDA with the benefits under any such lease, contract,
license, claim or right, including, without limitation, enforcement for the
benefit of HDA of any and all rights of the Companies against a third party
thereto arising out of the breach or cancellation by such third party or
otherwise.

          8.2.  Indemnification by the Selling Parties.  Subject to the
                --------------------------------------
provisions of this Article VIII, the Popes will jointly and severally indemnify,
defend and hold HDA and its respective stockholders, subsidiaries, officers,
directors, employees, agents, successors and assigns, (such indemnified persons
are collectively hereinafter referred to as "HDA's Indemnified Persons"),
harmless from and against any and all loss, liability, damage (excluding
consequential, indirect special, exemplary and punitive damages) or deficiency
(including interest, penalties, judgments, costs of preparation and
investigation, and reasonable attorneys' fees) (collectively, "Losses") that
HDA's Indemnified Persons may suffer, sustain, incur or become subject to
arising out of or due to: (a) the breach of any representation or warranty of
the Selling Parties in this Agreement, (b) the nonfulfillment of any covenant,
undertaking, agreement or other obligation of the Selling Parties under this
Agreement, not otherwise waived by HDA, or (c) the failure of Truck to qualify
in a timely manner to do business in Florida or South Carolina. "Losses" as used
herein is not limited to matters asserted by third parties, but includes Losses
incurred or sustained in the absence of third party claims. Payment is not a
condition precedent to recovery of indemnification for Losses.

          8.3.  Indemnification by HDA.  Subject to the provisions of this
                ----------------------
Article VIII, HDA agrees to indemnify, defend and hold the Selling Parties and
their respective heirs, representatives, agents, successors and assigns (such
persons are hereinafter collectively referred to as the "Selling Parties'
Indemnified Persons"), harmless from and against any and all Losses that Selling
Parties' Indemnified Persons may suffer, sustain, incur or become subject to
arising out of or due to: (a) the breach of any representation or warranty of
HDA in this Agreement and (b) the nonfulfillment of any covenant, undertaking,
agreement or other obligation of HDA under this Agreement, not otherwise waived
by the Selling Parties.

          8.4.  Survival of Representations, Warranties and Covenants.  The
                -----------------------------------------------------
several representations, warranties, covenants of the Parties contained in this
Agreement or in any document delivered pursuant hereto and the Parties' right to
indemnity in accordance with this Article VIII shall survive until the first
anniversary of the Closing Date; provided, however, that the representations and
warranties set forth in Section 3.12 relating to tax matters and Section 3.19
relating to employee benefits matters shall survive for the length of the
applicable statute of 

                                       31

 
limitations, and provided further that the representations in Sections 3.2, 3.4
and 3.30(b) shall survive indefinitely.

          8.5.  Threshold; Deductible.  Except as provided in this Section 8.5,
                ---------------------
no HDA's Indemnified Person or Selling Parties' Indemnified Person shall be
entitled to any recovery in accordance with this Article 8 unless and until the
amount of such Losses suffered, sustained or incurred by such party, or to which
such party becomes subject, by reason of such inaccuracy, breach or
nonfulfillment exceeds $125,000 and then only to the extent of such excess.
Indemnification pursuant to this Agreement shall constitute the sole and
exclusive monetary remedy of the Parties with respect to any breach of the
representations, warranties, covenants or agreements contained in this Agreement
or arising out of the transactions contemplated hereby; provided, however, that
if the indemnification provisions in this Agreement are unenforceable, any Party
may pursue any other remedy, subject in all cases to the $125,000 deductible and
$3,500,000 cap set forth in this Section. Notwithstanding any other provision
contained in this Agreement or the Ancillary Agreements to the contrary, in no
event shall the Selling Parties have any liability for indemnification pursuant
to Section 8.2, the other terms of this Agreement or the Ancillary Agreements in
an aggregate amount in excess of $3,500,000, except for liabilities relating to
the breach of tax representations and warranties, as to which neither the
$125,000 deductible nor the $3,500,000 cap apply.

          8.6.  Notice and Opportunity to Defend.  If a claim for Losses (a
                --------------------------------
"Claim") is to be made by a party seeking indemnification hereunder, such party
seeking indemnification (the "Indemnitee") shall notify the party obligated to
provide indemnification (the "Indemnitor") promptly. If such event involves (a)
any claim or (b) the commencement of any action or proceeding by a third person,
the Indemnitee shall give the Indemnitor written notice of such claim or the
commencement of such action or proceeding. Delay or failure to so notify the
Indemnitor shall only relieve the Indemnitor of its obligations to the extent,
if at all, that it is prejudiced by reasons of such delay or failure. The
Indemnitor shall have a period of 30 days within which to respond thereto. If
the Indemnitor accepts responsibility or does not respond within such 30-day
period, then the Indemnitor shall be obligated to compromise or defend, at its
own expense and by counsel chosen by the Indemnitor, such matter, and the
Indemnitor shall provide the Indemnitee with such assurances as may be
reasonably required by the Indemnitee to assure that the Indemnitor will assume
and be responsible for the entire liability at issue, subject to the limitations
set forth in Sections 8.4 and 8.5 hereof. If the Indemnitor fails to assume the
defense of such matter within said 30-day period, the Indemnitee against which
such matter has been asserted will (upon delivering notice to such effect to the
Indemnitor) have the right to undertake, at the Indemnitor's cost and expense,
the defense, compromise or settlement of such matter on behalf of the
Indemnitee. The Indemnitee agrees to cooperate fully with the Indemnitor and its
counsel in the defense against any such asserted liability. In any event, the
Indemnitee shall have the right to participate at its own expense in the defense
of such asserted liability. Any compromise of such asserted liability by the
Indemnitor shall require the prior written consent of the Indemnitee, which
consent will not be unreasonably withheld and in the event the Indemnitee
defends any such asserted liability, then any compromise of such asserted
liability by the Indemnitee shall require the prior written consent of the
Indemnitor, which consent shall not be unreasonably withheld.

                                       32

 
          8.7.  Indemnification Payments.  At the Closing, the Selling Parties
                ------------------------
will deliver by wire transfer of immediately available funds $850,000 of the
Cash Purchase Price to the Escrow Agent to serve as partial security for the
indemnification obligations and Purchase Price adjustment obligations of the
Selling Parties under this Agreement.

                                  ARTICLE IX.
