                                   AGREEMENT

          NOW, THEREFORE, in consideration of the promises and the mutual
covenants and agreements set forth herein, the Parties hereby agree as follows:


                                   ARTICLE I.

                               PURCHASE AND SALE

          1.1   Purchase Price.
                -------------- 


          (a)   Upon the terms and subject to the conditions set forth herein,
HDA will purchase from the Existing Shareholders all of the capital stock of the
Company for a price (the "Purchase Price") determined as follows:   (i) Eleven
Million Seven Hundred Thousand Dollars ($11,700,000) in cash payable by wire
transfer of immediately available funds to the Existing Shareholders, less the
                                                                      ----    
amount of any long-term liabilities listed on Schedule 1.1 and the current
portion thereof outstanding as of the Closing (as defined), (ii) 4,578 shares of
Common Stock of City Truck Holdings, Inc. ("Holdings"), par value $.01 per share
(the "Common Stock"), and (iii) 19,954.218 shares of Series A Preferred Stock of
Holdings, par value $.01 per share (the "Series A Preferred Stock"), subject to
the holdback deposited into escrow as set forth below in Section 1.1(c).

          (b)   HDA agrees to pay to the Existing Shareholders the Purchase
Price by wire transfer or delivery of other immediately available funds and by
delivery of the shares of 

                                       1

 
Common Stock and Series A Preferred Stock referred to in Section 1.1(a) above
which are not held back pursuant to Section 1.1(c) below.


          (c)   The "Holdback Amount" shall be 2,289 shares of Common Stock and
9,977.109 shares of Series A Preferred Stock of the Purchase Price which HDA, at
the Closing, shall deposit with the Escrow Agent (as defined below) subject to
the terms and conditions of the Escrow Agreement (as defined below).  Such
holdback deposited into escrow is for the purposes referred to in Section 8.6
below. .

          1.2.  Purchase Price Adjustment. If any distributions in excess of
                -------------------------
$130,000 are made by the Company to any Existing Shareholder or any persons
related directly or indirectly by blood or marriage to any Existing Shareholder
or to an entity controlled by any of the foregoing between June 30, 1998 and the
Closing, the Purchase Price shall be reduced by the amount of the excess. In
addition, to the extent the Company has already paid any costs or expenses which
are to be borne by the Existing Shareholders pursuant to Section 9.1, the
Purchase Price will be reduced by that amount.

          1.3.  Closing Balance Sheet
                ---------------------
          

          (a)   Closing Balance Sheet.  The Existing Shareholders will prepare a
                ---------------------                                           
balance sheet dated the Closing Date (as defined) (the "Closing Balance Sheet"),
prepared in accordance with generally accepted accounting principles ("GAAP"),
applied consistently with the Company's respective past practice to the extent
such practice is GAAP.  The Existing Shareholders will deliver such Closing
Balance Sheet to HDA within 45 days after the Closing.  At HDA's election, the
Closing Balance Sheet shall be audited by McGladrey & Pullen, LLP.  HDA shall
allow the Existing Shareholders and their authorized professionals reasonable
access to the financial information of HDA in order to prepare the Closing
Balance Sheet.

          (b)   Closing Balance Sheet Notice.   
                ----------------------------

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


                (ii) If the Closing Balance Sheet Notice is not timely given as
     described in Section (b)(i), the Closing Balance Sheet shall be final,
     binding and conclusive upon the Parties.  If HDA disagrees with the Closing
     Balance Sheet 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 Balance 

                                       2

 
     Sheet Notice, such dispute will be resolved by a "Big 5" accounting firm
     ("BFAF") selected by HDA and the Company.

                (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 Balance
     Sheet only to the extent necessary to make it conform to the practices,
     procedures and methods described in Section 1.3(a) above.

                                  ARTICLE II.

later date upon which the Parties mutually agree (the "Closing Date").

          (b)   The audited statements of operations, statements of changes in

The minute books of the Company accurately and adequately reflect all action
taken by the shareholders, board of directors and committees of the board of
directors of the Company. The copies of the stock book records of the Company
are true, correct and complete, and accurately reflect all transactions effected
in the Company's stock interests through and including the date hereof. The
Company has not engaged in any transaction, maintained any bank account or used
any corporate funds except for the transactions, bank accounts and funds which

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. The Company is not in violation of or default under any

is in compliance with all applicable laws, statutes, ordinances and regulations.
The Company has not 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.

          3.11. 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,

                                       7

 
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)   The 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 respects.  All Taxes owed by the Company (whether or not shown
on any Tax Return) have been paid.  The Company currently is not the beneficiary
of any extension of time within which to file any Tax Return.  No claim has ever
been made by an authority in a jurisdiction where the Company does not file Tax
Returns that the Company is or may be subject to taxation by that jurisdiction.
There are no liens on any of the assets of the Company that arose in connection
with any failure (or alleged failure) to pay any Tax.

          (c)   The 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 the
Company either (i) claimed or raised by any authority in writing or (ii) of
which the Company or any Existing Shareholder has knowledge.  To the knowledge
of the Company and each Existing Shareholder, no audit or examination of any Tax
Return is currently in progress, and the Company has not received notice of any
proposed audit or examination.  The 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 the Company with respect to years ended on or before September 30, 1997.
The Company has not  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)   The Company has not filed a consent under Section 341(f) of the
Code concerning collapsible corporations (or any comparable state income tax
provision).  The Company has not made any payments, is not obligated to make any
payments, and is not 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.  The Company is not a party to any Tax allocation, sharing or
indemnity agreement.  The Company (i) has not been a member of an affiliated
group of corporations filing a consolidated federal income Tax Return or (ii)
has no  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.  Schedule 3.11 hereto sets forth all material
elections (e.g., accelerated depreciation, Sec. 263(a) regarding the 

                                       8

 
allocation of overhead to inventory, and FIFO election for inventory accounting)
in effect as of the date hereof with respect to Taxes affecting the Company.

          (f)   The unpaid Taxes of the Company 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.  The 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 periods covered thereby.

          3.12. Brokers, Finders.  The Company has not retained any broker or
                ----------------
finder 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.

          3.13. Absence of Certain Changes.
                --------------------------

     other than in the ordinary course of business;

     in base compensation in the ordinary course consistent in timing and amount
     with past practices), or entry into or variation of the terms of any
     employment or incentive agreement with any such person;

                (xiii) an adverse change in employee relations which has or is

The Company has furnished or will furnish to HDA or its representatives true and
correct copies of all Material Contracts prior to the Closing, including all

          3.15. Proprietary Rights.
                 ------------------ 

          (a)   Schedule 3.15 lists the material patents, trademarks (whether
registered or unregistered), service marks, trade names, service names, brand
names, logos and copyrights (collectively, the "Proprietary Rights") for the
Company.  Schedule 3.15 also sets forth:  (i) for each patent, the number,
normal expiration date and subject matter for each country in which such patent
has been issued, or, if applicable, the application number, date of filing and
subject matter for each country, (ii) for each trademark, the application serial
number or registration number, the class of goods covered and the expiration
date for each country in which a trademark has been registered and (iii) for
each copyright, the number and date of filing for each country in which a
copyright has been filed.  The Proprietary Rights listed in Schedule 3.15 are
all those used by the Company in connection with its businesses.  True and
correct copies of all patents (including all pending applications) owned,
controlled, created or used by or on behalf of the Company or in which the
Company has any interest whatsoever have been provided to HDA or its
representatives.

          (b)   The Company has no obligation to compensate any person for the
use of any such Proprietary Rights nor has the Company granted to any person any
license, option or 

                                       12

 
other rights to use in any manner any of its Proprietary Rights, whether
requiring the payment of royalties or not.

          (c)   The Company owns or has a valid right to use each of the
Proprietary Rights, and the Proprietary Rights will not cease to be valid rights
of the 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.  All of the pending patent applications have
been duly filed.  The Company has not received any notice of invalidity or
infringement of any rights of others with respect to such trademarks.  The
Company has taken all reasonable and prudent steps to protect the Proprietary
Rights from infringement by any other person.  No other person (i) has the right
to use any trademarks the Company on the goods on which they are now being used
either in identical form or in such near resemblance thereto as to be likely,
when applied to the goods of any such person, to cause confusion with such
trademarks or to cause a mistake or to deceive, (ii) has notified the Company
that it is claiming any ownership of or right to use such Proprietary Rights, or
(iii) to the best knowledge of the Company, is infringing upon any such
Proprietary Rights in any way.  The 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 the Company that are presently
outstanding, alleging that the Company's use of the Proprietary Rights infringes
upon or otherwise violates any rights of a third party in or to such Proprietary
Rights.  There are not, and it is reasonably expected that after the Closing
there will not be, any restrictions on right of the Company to sell products
manufactured by the Company in connection with the operation of its business.

          3.16. Labor Matters. The Company is not a party to any labor agreement
                -------------
with respect to its employees with any labor organization, union, group or
association, and there are no employee unions (nor any other similar labor or
employee organizations) under local statutes, custom or practice. The Company
has not 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

          5.7.  Tax Matters.
                ----------- 

          (a)   The Company shall timely prepare and file, or cause to be
prepared and filed, with the appropriate authorities all Tax Returns of the
Company for all taxable periods of the Company ending on or prior to the Closing
Date ("Preclosing Periods").  The Company shall deliver such Tax Returns to HDA
or its representatives and obtain HDA's consent thereto, which consent shall not
be unreasonably withheld or delayed, prior to the filing thereof.  The Existing
Shareholders shall timely pay, or cause to be paid, when due all Taxes relating
to the periods covered by such Tax Returns and not accrued on the Balance
Sheets.

          (b)   The Company shall prepare or complete, or cause to be prepared
or completed, and timely filed, or cause to be timely filed, all Tax Returns of
the Company required to be filed after the Closing Date and, subject to Section
5.7(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 5.7(a), with respect to Tax
Returns of the Company 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 the Company in a manner consistent
with the prior practice of the Company, and in a manner that does not

                                       30

 
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).

          (c)   Although the Company, as the taxpayer or in connection with
filing the Tax Returns specified in Section 5.7(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, the Existing Shareholders will
be responsible for such Pre-Closing Taxes either by payment of such Pre-Closing
Taxes themselves or pursuant to this Section 5.7.

          (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 ("Tax Proceeding").  The Existing Shareholders
shall have the sole right to control, conduct, and otherwise represent the
interests of the 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 the Company 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 the Company, 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 5.7(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 5.7, 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.

                                       31

 
          (a)   (f)  After the date hereof, HDA and the Company shall provide
each other and the Existing Shareholders, with such cooperation and information
relating to the Company 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 the Company 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 5.7 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.

Schedule hereto, not otherwise waived by the Existing Shareholders.

          8.3.  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 the Closing Date
and shall remain in full force and effect for one (1) year thereafter; provided,
however, that the representations and warranties set forth in Section 3.11

shall survive for the length of the applicable statute of limitations and that

warranties contained in Section 3.4 (Capitalization of the Company), Section 3.5
(Title to Shares), Section 3.11 (Tax Matters) and Section 3.18 (Employee Benefit
Plans; Employment Agreements) shall not be subject to the $50,000 deductible or
the Purchase Price ceiling.

          8.5.  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 8.3 and 8.4 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.

          8.6   Indemnification Payments. At the Closing, HDA deposit into
                ------------------------
escrow, in accordance with the terms and conditions of the Escrow Agreement,
2,289 shares of Common Stock and 9,977.109 shares of Series A Preferred Stock
(the "Escrow Stock") of the Purchase Price to serve as partial security for the
indemnification obligations, if any, of the Company and the Existing
Shareholders under this Agreement; provided, however, that the Existing
                                   --------
Shareholders may satisfy any such indemnification obligations in cash rather
than in Escrow Stock. To the extent the Existing Shareholders elect to satisfy
indemnification obligations under this Agreement in cash rather than Escrow
Stock, HDA will direct the Escrow Agent to release to the Existing Shareholders
a number of shares of Escrow Stock equal in value to the amount of such cash
payment (to be valued as set forth in the Escrow Agreement). The Escrow 
Agreement
                                       36

 
will provide that at the end of the one year survival period set forth in
Section 8.3 above the Escrow Agent will deliver the Escrow Stock to the Existing
Shareholders, less any shares of Common Stock or Series A Preferred Stock
previously paid out of the Escrow Amount to HDA and less a number of shares
equal in value to any amount which is the subject of an unresolved, disputed or
pending claim (to be valued as set forth in the Escrow Agreement), in accordance
with the terms and conditions of the Escrow Agreement.

                                  ARTICLE IX.
                                 MISCELLANEOUS

          9.1.  Expenses. Except as otherwise set forth in this Agreement, each
                --------
Party shall bear its own expenses and costs incurred by it in preparing,
negotiating and closing this Agreement, except that the Existing Shareholders
will also bear all expenses and costs incurred by the Company.

                -------------
and enforced in accordance with the internal laws of the State of Connecticut
applicable to contracts made in that State, without giving effect to the
conflicts of laws principles thereof.

          9.8.  Further Assurances. Each Party agrees that it will execute and
                ------------------
deliver, or cause to be executed and delivered, on or after the date of this
Agreement, all such other instruments and will take all reasonable actions as
may be necessary in order to consummate the transactions contemplated hereby,
and to effectuate the provisions and purposes hereof.

          9.9.  No Third-Party Rights. This Agreement is not intended, and shall
                ---------------------  
not be construed, to create any rights in any parties other than the Company,
HDA and the Existing Shareholders, and no person shall assert any rights as
third-party beneficiary hereunder.

          9.10  Non-Waiver. The failure in any one or more instances of a Party
                ----------
hereto to insist upon performance of any of the terms, covenants or conditions
of this Agreement, to exercise any right or privilege in this Agreement
conferred, or the waiver by said Party of any breach of any of the terms,
covenants or conditions of this Agreement shall not be construed as a subsequent
waiver of any such terms, covenants, conditions, rights or privileges, but the
same shall continue and remain in full force and effect as if no such
forbearance or waiver had occurred.

          9.11  Severability. If any term or other provision of this Agreement
                ------------
is invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner adverse to
any Party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the Parties hereto shall negotiate in
good faith to modify this Agreement so as to affect the original intent of the
Parties as closely as possible in an acceptable manner to the end that
transactions contemplated hereby are fulfilled to the extent possible.

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

                ---------
