SECTION 3.1.  CONSENT OF UAG.

       (a)  Subject to the rights of Smith contained in Sections 3.3(b) and

       No Shareholder (including UAG/Atlanta and any other Shareholder 
permitted to Transfer shares of capital stock of the Company or any interest 
therein in accordance with Section 3.1 hereof) shall, directly or indirectly, 
Transfer any shares of capital stock of the Company or any interest therein, 
whether voluntarily or involuntarily, unless:

       (a) (i) such Transfer complies with the provisions of this Agreement, 
including Section 3.3 hereof, if applicable, and (ii) the transferee (if other
than another Shareholder) agrees to



                                        -6-


be bound by this Agreement and executes a counterpart hereof and such further 
documents as may be necessary, in the opinion of the Company, to make it a 
party hereto (any such transferee shall be deemed to be a Shareholder for 
purposes of this Agreement); and

       (b) such Transfer is made pursuant to either (i) an effective 
registration statement under the Securities Act and any applicable state 
securities laws, or (ii) an available exemption from the registration 
requirements of the Securities Act and such laws and, prior to any such

the Transfer provides to the Company a written opinion of legal counsel 
satisfactory in form and substance to the Company and its counsel to the 
effect that the proposed Transfer may be effected without registration under 
the Securities Act and any applicable state securities laws.

SECTION 3.3.  RIGHT OF FIRST REFUSAL AND CO-SALE RIGHTS AND OBLIGATIONS.

       (a) RIGHT OF FIRST REFUSAL.

           (i) FIRST OFFER NOTICE.  Except as otherwise permitted by Section 
3.1(b) hereof, subject to Section 3.1(a) hereof, at any time prior to the 
Public Float Date, no Shareholder (other than UAG/Atlanta (or an Affiliate 
thereof)) shall transfer all or any of his shares of Common Stock (which 
shall include all or any Common Stock Equivalents) (the "Offered Shares") 
unless (x) such Shareholder (the "Selling Shareholder") has received a bona 
fide written offer (the "Purchase Offer") from the proposed transferee of 
the Offered Shares (the "Purchaser") to purchase the Offered Shares, which 
offer shall be in writing signed by the Purchaser, and (y) the Selling 
Shareholder first offers to sell to UAG/Atlanta the Offered Shares.  Prior 
to making any transfer that is subject to this Section 3.3(a), the Selling 
Shareholder shall give UAG/Atlanta written notice (the "Offer Notice") which 
shall include (x) the identity of the Purchaser, (y) a copy of the Purchase 
Offer, and (z) an offer (the "First Offer") to sell to UAG/Atlanta the 
Offered Shares upon the same terms and conditions as those provided for in 
the Purchase Offer.  The First Offer shall be irrevocable for a period of 
thirty (30) days following receipt by UAG/Atlanta of the Offer Notice (the 
"First Offer Period").

           (ii)  ACCEPTANCE OF FIRST OFFER.  At any time during the First Offer
Period, UAG/Atlanta may accept the First Offer of the Offered Shares by 
giving written notice to the Selling Shareholder of such acceptance.  In the 
event UAG/ Atlanta accepts the First Offer, the closing of the sale of the 
Offered Shares shall take place within thirty (30) days after the First 
Offer is accepted by UAG or, if later, the date of closing set forth in the 
Purchaser Offer.  At such



                                        -7-


closing, the Selling Shareholder will deliver certificates for such Offered 
Shares against payment of the purchase price therefor, and UAG/Atlanta will 
acquire the Offered Shares free and clear of all liens, pledges, 
encumbrances, restrictions and security interests of any kind.  If 
UAG/Atlanta does not accept the First Offer, the Selling Shareholder may sell 
the Offered Shares to the Purchaser at any time within thirty (30) days after 
the last day of the First Offer Period, provided that such sale shall be made 
on terms no less favorable to the Selling Shareholder than the terms 
contained in the Purchase Offer and provided further that such sale complies 
with the terms, conditions and restrictions of this Agreement.  In the event 
that the Offered Shares are not sold in accordance with the terms of the 
preceding sentence, the Offered Shares shall again be subject to all of the 
conditions and restrictions of this Section 3.3(a).

       (b) TAG-ALONG-RIGHT.

           (i)  TAG-ALONG SALE NOTICE.  If, at any time prior to the Public 
Float Date, UAG/Atlanta (or an Affiliate thereof) receives a bona fide offer 
(a "Tag-Along Offer") from a third party to purchase shares of Common Stock 
from UAG (or an Affiliate thereof) or UAG/Atlanta otherwise proposes to sell 
shares of Common Stock for value, in each case other than in connection with 
a Public Offering (a "Tag-Along Sale"), UAG/Atlanta shall be required to 
notify Smith, not less than fifteen (15) days prior to such proposed Tag-
Along Sale, of such Tag-Along Offer or proposed Tag-Along Sale and Smith 
shall have the option to participate in such Tag-Along Sale as set forth in 
clause (ii) of this Section 3.3(b). The notice from UAG/Atlanta (the "Tag-
Along Sale Notice") shall set forth: (A) the number of shares of Common 
Stock proposed to be transferred, (B) the name and address of the proposed 
purchaser, (C) the proposed amount of consideration and terms and conditions 
of payment offered by or to such proposed purchaser, and (D) that the 
proposed purchaser has been informed of the "tag-along" rights provided for 
in this Section 3.3(b) and has agreed to purchase shares of Common Stock in 
accordance with the terms hereof.

           (ii)  TAG-ALONG RIGHT.  Any time prior to the Public Float Date, 
Smith shall have the right to require the proposed purchaser to purchase 
from him a number of whole shares of Common Stock up to the number of shares 
equal to the total number of shares to be sold to the proposed purchaser 
multiplied by a fraction, the numerator of which is the number of shares of 
Common Stock held by him and the denominator of which is the total number of 
shares of Common Stock held by him and UAG (or an Affiliate thereof).  Any 
shares of Common Stock purchased from Smith pursuant to this Section 3.3(b) 
shall be paid for upon the same terms and conditions (includ-


                                        -8-


ing as to price and type of consideration) received by UAG/Atlanta.

           (iii)  TAG-ALONG NOTICE.  If Smith elects to exercise the tag-along 
right provided for in this Section 3.3(b), he must deliver written notice to 
UAG/Atlanta (the "Tag-Along Participation Notice") within five (5) days 
following receipt by him of the Tag-Along Sale Notice.  If Smith does not 
deliver a Tag-Along Participation Notice within such five-day period he 
shall be deemed to have waived his tag-along right with respect to the 
proposed Tag-Along Sale.  Each Tag-Along Participation Notice shall state 
the number of shares of Common Stock that Smith proposes to include in such 
transfer to the proposed purchaser up to the number of shares determined in 
accordance with Section 3.3(b)(ii) hereof.

       (c) TAKE-ALONG RIGHT.

           (i)  TAKE-ALONG NOTICE.  If UAG/Atlanta (or an Affiliate thereof) 
at any time receives a bona fide offer from a third party to purchase shares 
of Common Stock from UAG/Atlanta (or an Affiliate thereof) or UAG/Atlanta
(or an Affiliate thereof) otherwise proposes to sell shares of Common Stock 
for value (a "Take-Along Sale"), UAG/Atlanta can require the other 
Shareholders, to participate in such Take-Along Sale as set forth in clause 
(ii) of this Section 3.3(c). If UAG/Atlanta elects to exercise the take-
along right provided for in this Section 3.3(c), it must provide, at least 
twenty (20) days before the date of consummation of the proposed Take-Along 
Sale, notice to each other Shareholder setting forth: (i) the number of 
shares of Common Stock proposed to be transferred, (ii) the number of shares 
of Common Stock that such Shareholder must include in such transfer to the 
proposed purchaser as determined in accordance with clause (ii) of this 
Section 3.3(c), (iii) the name and address of the proposed purchaser, (iv) 
the proposed amount of consideration and terms and conditions of payment 
offered by or to such proposed purchaser, and (v) that the proposed 
purchaser has been informed of the "take-along" rights provided for in this 
Section 3.3(c) and has agreed to purchase shares of Common Stock in 
accordance with the terms hereof.

           (ii)  TAKE-ALONG RIGHT.  UAG/Atlanta shall at any time have the 
right to require each other Shareholder to sell to the proposed purchaser a 
number of whole shares of Common Stock up to the number of shares equal to 
the total number of shares to be sold to the proposed purchaser multiplied 
by a fraction, the numerator of which is the number of shares of Common 
Stock held by such other Shareholder and the denominator of which is the 
total number of shares of Common Stock held by all of the Shareholders, 
including UAG/Atlanta (or an Affiliate thereof).  Any shares of Common Stock 
purchased


                                        -9-


from Shareholders other than UAG/Atlanta pursuant to this Section 
3.3(c) shall be paid for upon the same terms and conditions (including price 
and type of consideration) received by UAG/Atlanta.

SECTION 3.4. LEGENDS ON STOCK CERTIFICATES.  

       For so long as shares of capital stock of the Company held by a Share-
holder are subject to this Agreement, all certificates representing such shares 
shall bear the following legend:

       The securities represented by this certificate are subject to 
       restrictions on transfer and certain other provisions of the 
       Shareholders' Agreement, dated as of July 26, 1996, as the same 
       may be amended from time to time, by and among United Auto 
       Group, Inc., UAG Atlanta, Inc., Inc., Atlanta Toyota (the 
       "Company"), John Smith and certain other shareholders of the 
       Company who may from time to time become parties to such 
       Shareholders' Agreement, a copy of which may be obtained at the 
       offices of the Company.

SECTION 3.5. IMPROPER TRANSFERS INEFFECTIVE.  

       Any purported transfer of Common Stock by a Shareholder which is not 
permitted by the foregoing provisions of this Article 3, or which is in 
violation of such provisions, shall be void and of no force and effect 
whatsoever.

                              ARTICLE 4
                        EXCHANGE; LOAN TO SMITH

SECTION 4.1.  EXCHANGE FOR UAG COMMON STOCK.

       (a)  In the event of an underwritten public offering  pursuant to an 
effective registration statement under the Securities Act covering the offering 
and sale of common stock, par value $.0001 per share, of UAG ("UAG Common 
Stock") for the account of UAG on a firm commitment basis (the "UAG Public 
Offering"), Smith (and any transferee or Affiliate of Smith holding shares of 
Common Stock) shall be required to exchange all shares of Common Stock 
beneficially owned by them (and their transferees and Affiliates) (the "Smith 
Interest") immediately prior to the closing of the UAG Public Offering for 
shares of UAG Common Stock under the terms and conditions set forth below, and 
UAG shall be required to exchange the Smith Interest for UAG Common Stock (such 
exchange is hereinafter referred to as the "UAG Exchange").



                                        -10-



       (b)  If the parties are required to consummate the UAG Exchange, the 
value of UAG (the "UAG Value") and the Company (the "Company Value") shall be 
determined by the investment banking firm which is acting as managing 
underwriter (the "Managing Underwriter") for the UAG Public Offering and such 
determination shall be binding upon the parties hereto.  In determining the 
Company value, the Managing Underwriter shall satisfy itself that UAG's 
overhead expenses are attributed to the Company and UAG's other subsidiaries 
equitably. The value of the Smith Interest (the "Smith Interest Value") shall 
be an amount equal to (A) the Company Value multiplied by (B) a fraction, the 
numerator of which shall be equal to the aggregate number of shares of Common 
Stock comprising the Smith Interest immediately prior to the UAG Exchange, 
and the denominator of which shall be the total number of shares of Common 
Stock outstanding immediately prior to the UAG Exchange.  The additional cost 
which the Managing Underwriter charges to compute the UAG Value and the 
Company Value shall be paid by UAG.

       (c)  The number of shares of UAG Common Stock to which Smith is 
entitled upon the consummation of the UAG Exchange (the "Smith Exchanged 
Shares") shall be determined by multiplying the Smith Interest Percentage (as 
defined below) by the total number of shares of UAG Common Stock outstanding 
immediately prior to the closing of the UAG Public Offering, which such 
number of shares shall include all shares of UAG Common Stock issued in 
respect of the Smith Interest pursuant to this Section 4.1 and to holders of 
minority interests (the "Other Minority Holders") in subsidiaries of UAG (the 
"Other Minority Interests") pursuant to agreements comparable to the 
agreement contained in this Section 4.1 (collectively, the "Minority 
Shares"), but shall not include any other shares of UAG Common Stock issuable 
upon the exercise, conversion or exchange of all then outstanding rights, 
warrants, options, indebtedness or other securities exercisable or 
exchangeable for, or convertible into, directly or indirectly, UAG Common 
Stock (collectively, "UAG Common Stock Equivalents").  Specifically, the 
number of Smith Exchange Shares shall be determined by multiplying (A) the 
number of Total Exchanged Shares (as defined below) by (B) a fraction, the 
numerator of which shall be equal to the Smith Interest Percentage, and the 
denominator of which shall be equal to the Total Interest Percentage (as 
defined below).  For purposes of this Section 4.1, (i) the "Smith Interest 
Percentage" shall be determined by dividing the Smith Interest Value by the 
UAG Value, (ii) the "Total Interest Percentage" shall equal the sum of all of 
the "Minority Interest Percentages," each of which shall be determined 
pursuant to the agreements between UAG and the Other Minority Holders 
relating to the exchange of the Other Minority Interests for shares of UAG 
Common Stock in connection with the UAG Public Offering, and (iii) the "Total 
Exchanged Shares" shall be determined by dividing (A) the product of (x) the 
Total Interest Percentage and (y) the total number of shares of UAG Common 
Stock outstanding immediately prior to the closing of the UAG Public Offering 
(the

                                        -11-



"Outstanding UAG Shares") (not including the Minority Shares and any shares 
of UAG Common Stock issuable upon the exercise, conversion or exchange of any 
UAG Common Stock Equivalent) by (B) an amount equal to 1 minus the Total 
Interest Percentage.  Expressed as a formula, the number of Smith Exchanged 
Shares shall be determined as follows:

             (TIP  X  OUS)    WIP
