SECTION 1.1.  CONSENT OF UAG WEST.

          (a)   Subject to the rights of Knappenberger Trust contained in
Article 3 hereof and except as otherwise provided herein and for as long as UAG
West (or an affiliate thereof) shall own at least 20% of the issued and
outstanding shares of Common Stock, no Shareholder other than UAG West shall

interest therein, or the stock certificate or certificates representing any such
shares, or any voting trust certificate or certificates issued with respect to
such shares, without the prior written consent of UAG West and Porsche Cars of
North America, Inc. ("Porsche").  Any Transfer effected, or purported or
attempted to be effected, not in accordance with the terms and conditions of
this Section 1.1, or to a Person prohibited by law from holding shares of
capital stock of the Company, shall be void and shall not bind the Company.  As

transferring, creating a security interest, lien or trust (voting or otherwise),
assigning or otherwise encumbering or disposing of, and (ii) when used as a
noun, any sale, pledge, mortgage, hypothecation, gift, transfer, creation of
security interest, lien or trust, any assignment or other encumbrance or
disposition.

SECTION 1.2.  GENERAL RESTRICTIONS.

          No Shareholder (including UAG West and any other Shareholder permitted
to Transfer shares of capital stock of the Company or any interest therein in
accordance with Section 1.1 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
and the Sales and Service Agreement; and (ii) the transferee (if other than
another Shareholder) agrees to be bound by this Agreement and the Sales and
Service 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 Transfer
(other than a Transfer to another Shareholder), the Person proposing the
Transfer provides to the Company a written opinion of legal counsel reasonably
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.

          Company, UAG West, United Auto Group, Inc. and Porsche Cars
          North America, copies of which may be obtained at the
          offices of the Company.

SECTION 1.4.   IMPROPER TRANSFERS INEFFECTIVE.

          Any purported transfer of Common Stock by a Shareholder which is not
permitted by the foregoing provisions of this Article 1, or which is in
violation of such provisions, shall be void and of no force and effect
whatsoever.


                                    ARTICLE 2
                           PURCHASE AND SALE OF SHARES

          Upon the occurrence of a Dealer Termination Event (as defined in the
Sales and Service Agreement) as to Knappenberger and subject to the consent and
approval of Porsche, UAG West shall have the right (the "Call") to acquire the
Knappenberger Shares for the Share Value (as defined below) for the purpose of
transferring, selling or assigning the Knappenberger Shares to a Dealer
Principal (as defined in the Sales and Service Agreement).  UAG West may
exercise the Call by notifying Knappenberger Trust in writing of such exercise.
Within five (5) days of receipt of such notice or such later date as is set
forth in the notice, Knappenberger Trust shall sell, assign, transfer and
deliver to UAG West the Knappenberger Shares and the certificates representing
such shares accompanied by stock powers duly executed in blank.  For purposes of
this Agreement, the Share Value shall be an amount equal to the Subsequent Value
(as defined in the Dealer Agreement) minus the sum of the Initial Value (as
defined in the Dealer Agreement) plus an amount equal to 15% of the Initial
Value per annum from the date hereof through the date the Knappenberger Shares
are transferred.


                                        3



          If, at any time, the Company ceases to operate a Porsche dealership,
Knappenberger Trust shall transfer, assign and deliver the Knappenberger Shares
to UAG West.

          As to any successor Dealer Principal consented to and approved by
Porsche, upon a Dealer Termination Event as to any such successor, such Dealer
Principal shall be required to sell and UAG West shall be required to purchase
the Company shares then held by such Dealer Principal on the terms and subject
to the conditions set forth in the Sales and Service Agreement.


                                    ARTICLE 3
                                  MISCELLANEOUS

SECTION 3.1.  TERM.

          All provisions of this Agreement shall terminate upon, in respect of
any Shareholder, when such Shareholder no longer owns any capital stock of the
Company.

SECTION 3.2.  AMENDMENT; WAIVER.

          This Agreement may be altered or amended only with the written consent
of all of the parties hereto and Porsche.  Any term of this Agreement and the
observance of any term herein may be waived (either generally or in a particular
instance and either retroactively or prospectively) by any party hereto only
with the written consent of such party, provided that any such waiver by any
party hereto shall not operate or be construed as a waiver of any other term or
observance of any term herein, whether or not similar.

SECTION 3.3.  SPECIFIC PERFORMANCE.

          The parties recognize that the obligations imposed on them in this
Agreement are special, unique and of extraordinary character, and that in the
event of breach by any party, damages will be an insufficient remedy;
consequently, it is agreed that the parties hereto may have specific performance
(in addition to damages) as a remedy for the enforcement hereof, without proving
damages.

any shares of Common Stock in accordance with the terms of this Agreement and
the Sales and Service Agreement; PROVIDED, HOWEVER, that the rights of

otherwise transferred in connection with any

written consent of UAG.  No assignment of this Agreement shall relieve the
assignor from any liability hereunder.
