                           RESTRICTED STOCK AGREEMENT

         This Restricted Stock Agreement (the "Agreement") is dated as of May
16, 2003 and is entered into between United Auto Group, Inc., a Delaware
corporation (the "Company"), and ____________ (the "Grantee").

                                   WITNESSETH:

         WHEREAS, the Company is granting the Grantee restricted shares of
voting common stock, par value $0.0001 per share (the "Common Stock"), of the
Company, on the terms and conditions set forth herein and in the 2002 United
Auto Group, Inc. Equity Compensation Plan (the "Plan").

         NOW, THEREFORE, the parties hereby agree:

         1. Defined Terms. Capitalized terms used in this Agreement and not
specifically defined herein shall have the respective meanings ascribed thereto
in the Plan. In the event of any inconsistency between the Agreement and the
Plan, the terms of the Plan shall govern.

         2. Authority. The shares of Common Stock issuable to the Participant
pursuant to this Agreement will be issued pursuant to the authority granted
under the Plan (which has been provided to Grantee), and are subject to the
terms and conditions of the Plan, as the same may be amended from time to time.
The interpretation and construction by the Committee of the Plan, this Agreement
and such rules and interpretations as may be adopted by the Committee for the
purpose of administering the Plan shall be final and binding upon the
Participant.

         3. Grant of Restricted Stock. The Company hereby grants to Grantee ___
restricted shares of Common Stock (the "Shares"). The Shares will be restricted
by being subject to vesting and non-transferability as hereafter provided in
this Agreement and shall be subject to such limitations on transfer as are
contained in the Plan, the federal and state securities laws applicable to the
Shares or any other limitations on transferability as may be imposed by the
Company.

         4. Risk of Forfeiture. The Shares will be subject to a substantial risk
of forfeiture. The Participant must continue in his or her employment as set
forth in the Plan on the vesting date(s) set forth below in order to vest in the
ownership of the Shares. If the Participant's employment with the Company is
terminated for any reason prior to the vesting date(s) as to any Shares, those
Shares shall revert to the Company, except as set forth in the Plan. This
Agreement is not an employment agreement and shall not confer on the Participant
any right to be retained in the employment of Company.

<PAGE>

         5. Restriction on Transfer. Until the Participant vests in the Shares,
the Shares may not be sold, assigned, transferred, pledged, hypothecated or
otherwise encumbered in any manner.

         6. Vesting of Shares. Subject to the restrictions set forth herein and
in the Plan, the Shares shall vest as follows:

         One-third of the shares shall vest on May 16, 2004; one-third of the
         shares shall vest on May 16, 2005; and the remaining one-third of the
         shares shall vest on May 16, 2006.

         7. Issuance of Certificates. As promptly as practicable after the date
hereof, the Company shall issue a certificate or certificates for the number of
Shares specified herein, or, at its sole option, shall direct the Company's
transfer agent to evidence the issuance hereunder by book-entry registration or
other means in the name of Grantee. If stock certificates are issued in respect
of the Shares, such certificates shall be deposited with the Company or its
designee, together with a stock power endorsed in blank. In any event, a legend
shall be placed upon such securities substantially as follows:

         THE SECURITIES REPRESENTED HEREBY ARE ISSUED PURSUANT TO A RESTRICTED
         STOCK AGREEMENT, DATED AS OF MAY 16, 2003 (THE "AGREEMENT"), BY AND
         BETWEEN UNITED AUTO GROUP, INC. AND THE PERSON IN WHOSE NAME THESE
         SECURITIES ARE REGISTERED. THE TERMS AND CONDITIONS OF THE AGREEMENT
         SUBJECT THESE SECURITIES TO A SUBSTANTIAL RISK OF FORFEITURE AND TO
         RESTRICTIONS ON TRANSFERABILITY.

At the expiration of the restricted period(s) applicable to the Shares, the
Company shall deliver to the Participant or the legal representative of the
Participant's estate stock certificates for such shares. If stock certificates
were previously issued for the shares and a legend has been placed on such
certificates, the Company shall cause such certificates to be reissued without
the legend.

         8. Voting. Unless the Committee shall determine otherwise, the
Participant shall be entitled to exercise any voting rights with respect to the
Shares and receive any dividends paid with respect thereto. In the event that
the outstanding securities of any class then comprising the Shares are
increased, decreased or exchanged for or converted into cash, property and/or a
different number or kind of securities, or cash, property and/or securities are
distributed in respect of such outstanding securities, in either case as a
result of a reorganization, merger, consolidation, recapitalization,
reclassification, dividend (other than a regular cash dividend) or other
distribution, stock split, reverse stock split or the like, then, unless the
Committee shall determine otherwise, the terms "Common Stock" or "Shares" shall,
from and after the date of such event, include such cash, property and/or
securities so distributed in respect of the

<PAGE>

Shares, or into or for which the Shares are so increased, decreased, exchanged
or converted.

                Whenever the word "Grantee" is used in any provision of this
Agreement under circumstances where the provision should logically be construed
to apply to the executors, the administrators or personal representatives, the
world "Grantee" shall be deemed to include such person or persons.

         9. Taxes.

         (i) Section 83(b) Election. The Participant understands that the
taxable income recognized by the Participant as a result of the award of Shares
hereunder, and the withholding liability and required date of withholding with
respect thereto, if any, will be affected by a decision by the Participant to
make an election pursuant to Section 83(b) of the Internal Revenue Code of 1986,
as amended (an "83(b) Election"). The Participant understands and agrees that
the Participant will have the sole responsibility for determining whether to
make an 83(b) Election with respect to the Shares, and for properly making such
election and filing the election with the relevant taxing authorities on a
timely basis. The Participant acknowledges that the Company has urged the
Participant to consult with the Participant's own tax advisor with respect to
the desirability of and procedures for making an 83(b) Election with respect to
the Shares, including when the election should be made. The Participant agrees
to submit to the Company a copy of any 83(b) Election with respect to the Shares
immediately upon filing such election with the relevant taxing authority.

         (ii) Withholding. By the execution of this Agreement, the Participant
agrees to pay to the Company the amount of federal, state and local taxes that
the Company is required to withhold and remit to the taxing authorities
applicable to the Participant as a result of the transactions contemplated by
this Agreement (collectively, "Taxes"). The Participant shall pay to the Company
an amount equal to the Taxes the Company is required to withhold and remit as
calculated by the Company in accordance with the rules and regulations of
applicable taxing authorities governing the calculation of such withholding. The
Participant shall make such withholding payment to the Company on the vesting
date(s) or upon the Participant making an 83(b) Election. If the Participant
does not make a Section 83(b) Election, the withholding can be satisfied by
having the Company retain from the Shares Common Stock having a fair market
value equal to the amount of the withholding obligation by completing the
election form attached hereto as Exhibit 1.

         If the Participant fails or refuses to make such payment to the Company
on its due date, the Participant hereby authorizes the Company, in addition to
any of its other remedies, to withhold from any other compensation or payments
due by the Company to the Participant an amount sufficient to pay such

<PAGE>

withholding plus interest as hereafter provided until such withholding and
interest is paid in full.

         10. Notice. Any notice required or permitted hereunder shall be in
writing and shall be sufficiently given if personally delivered or if sent by
telegram, telex, facsimile transmission or by registered or certified mail,
postage prepaid, with return receipt requested, as follows:

         NOW, THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, and intending to be legally bound hereby, the
parties hereto agree as follows:

         SECTION 1. Certain Amendments to Credit Agreement. The Credit Agreement
is hereby amended as follows:

         1.1. Section 1.01 of the Credit Agreement is hereby amended by adding
thereto, in appropriate alphabetical sequence, the following definitions:

                  "Covered Stock Repurchase Amount" shall mean (i) for any
         period of four consecutive fiscal quarters for which the Consolidated
         Leverage Ratio is 1.0 to 1.0 or less, zero and (ii) for any other
         period of four consecutive fiscal quarters, an amount equal to fifty
         percent of purchase price paid by the Parent or any subsidiary for
         purchases of capital stock of the Parent during such period.

                  "Current Maturities of Long Term Indebtedness" shall mean
         amounts becoming due during the period in question of principal of
         Indebtedness for borrowed

<PAGE>

         money other than (i) Indebtedness the original maturity date of which
         is less than one year from the date such Indebtedness was incurred and
         (ii) Indebtedness incurred under revolving credit or line of credit
         facilities to the extent such facilities permit reborrowing after
         repayment.

         1.2. The definition of the term "Consolidated Fixed Charge Coverage
Ratio" appearing in Section 1.01 of the Credit Agreement is hereby amended to
read in its entirety as follows:

                  "Consolidated Fixed Charge Coverage Ratio", as of the last day
         of any fiscal quarter, shall mean the ratio of (a) Consolidated EBITDA
         plus the aggregate amounts that were paid as rent by the Parent and its
         consolidated Subsidiaries minus Capital Expenditures of the Parent and
         its consolidated Subsidiaries minus charges against income for foreign,
         federal, state and local income Taxes of the Parent and its
         consolidated Subsidiaries to (b) Current Maturities of Long Term
         Indebtedness of the Parent and its consolidated Subsidiaries plus
         Consolidated Interest Expense plus the aggregate amounts that were paid
         as rent by the Parent and its consolidated Subsidiaries plus the
         aggregate amount of dividends and distributions on the shares of
         capital stock of the Parent plus the Covered Stock Repurchase Amount,
         in each case for the four most recently completed fiscal quarters
         ending on such day, considered as a single accounting period. If an
         Acquisition occurs during such period, each element of the Consolidated
         Fixed Charge Coverage Ratio shall be calculated on a pro forma basis as
         if the Acquisition had been made, and any Indebtedness or other
         obligations issued or incurred in connection therewith had been issued
         or incurred, as of the first day of such period; provided, however,
         that, in making such calculations, the Borrower may ignore those
         expenses and distributions of the acquired Person that would not have
         been incurred had the Acquisition occurred as of the first day of such
         period. In making such pro forma calculation of the Consolidated
         Interest Expense with respect to Indebtedness or other obligations
         issued or incurred in connection with the Acquisition, interest expense
         thereon shall be calculated on the basis of an interest rate per annum
         not less than the one-month Euro-Rate as of the last day of such period
         plus an Applicable Margin determined on the basis of the Consolidated
         Leverage Ratio as of the last day of such period.

         1.3. Section 7.02 of the Credit Agreement is hereby amended to read in
its entirety as follows:

                  7.02. Leverage. As of the last day of each fiscal quarter, the
         Consolidated Leverage Ratio shall no be greater than 2.0 to 1.0.

         1.4. The definition of the term "Prime Rate" appearing in Section 1.01
of the Credit Agreement is hereby amended by deleting the phrase "Mellon Bank,
N. A." each place it appears in such definition and inserting in lieu thereof
the phrase "Citizens Bank of Pennsylvania".

         SECTION 3. Miscellaneous.

         3.1. Effect of Amendment. This Amendment shall become effective upon
(a) the execution by the Borrower, the Guarantors, the Required Lenders and the
Agent, and delivery to the Agent, of this Amendment and (b) receipt by the Agent
of such other certificates, corporate documents and other documents as the Agent
may request. The Credit Agreement, as amended by this Amendment, is in all
respects ratified, approved and confirmed and shall, as so amended, remain in
full force and effect.

<PAGE>

         3.2. Confirmation of Guaranty. Each of the Guarantors reaffirms the
terms and conditions of the Loan Documents executed by it and acknowledges and
agrees that such Loan Documents remain in full force and effect and are hereby
ratified, reaffirmed and confirmed.

         3.3. Governing Law. This Amendment shall be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania without giving
effect to the conflict of law principles thereof.

         3.4. Counterparts. This Amendment may be executed in any number of
counterparts and by the different parties hereto on separate counterparts, each
of which, when so executed, shall be deemed an original, but all such
counterparts shall constitute but one and the same instrument.
