                           CERTIFICATE OF DESIGNATION
                                       OF
                      SERIES B CONVERTIBLE PREFERRED STOCK

     Pursuant to Section 151(g) of the General Corporation Law of the State of
Delaware, United Auto Group, Inc. (the "Corporation"), a corporation organized
and existing under the General Corporation Law of the State of Delaware
("DGCL"), DOES HEREBY CERTIFY that:

     Pursuant to the authority conferred upon the Board of Directors of the
Corporation by Section 1 of Article IV of the Certificate of Incorporation of
the Corporation (the "Certificate of Incorporation"), and in accordance with
the provisions of Section 151(g) of the DGCL, the Board of Directors of the
Corporation on April 9, 1999, adopted the following resolution creating a
series of Preferred Stock designated as Series B Convertible Preferred Stock.

     RESOLVED, that pursuant to the authority vested in the Board of Directors
of the Corporation in accordance with the DGCL and the provisions of the
Certificate of Incorporation, a series of the class of authorized Preferred
Stock, par value $0.0001 per share, of the Corporation is hereby created and
that the designation and number of shares thereof and the voting powers,
preferences and relative, participating, optional and other special rights of
the shares of such series, and the qualifications, limitations and restrictions
thereof, are as follows (capitalized terms used herein shall have the meanings
set forth in Section 11 hereto):

     SECTION 1. DESIGNATION; NUMBER; RANK.

     (a)  Designation Number.  The shares of such series shall be designated
"Series B Convertible Preferred Stock" (the "Series B Preferred Stock"). The
number of shares constituting the Series B Preferred Stock shall be 10,000. The
Corporation may issue (i) up to 8,300 shares of the Series B Preferred Stock as
an original issuance and (ii) such number of additional shares as may be
required to pay dividends on the Series B Preferred Stock, and in the case of
International Motor Cars Group II, L.L.C. the Series A Preferred Stock, in
additional shares of Series B Preferred Stock pursuant to Section 2(b) or
pursuant to Section 8, or in the case of International Motor Cars Group II,
L.L.C., pursuant to Section 2(b) of the Certificate of Designation of the
Series A Preferred Stock. The Corporation shall take all actions necessary or
advisable to increase the number of shares of Series B Preferred Stock
authorized to provide for additional issuance of Series B Preferred Stock
pursuant to clause (ii) of the preceding sentence.

     (b)  Rank.  The Series B Preferred Stock shall, with respect to dividend
rights and rights on liquidation, dissolution or winding up, rank (i) pari
passu to the Series A Preferred Stock, par value $0.0001 per share of the
Corporation (the "Series A Preferred Stock"), and (ii)

<PAGE>
senior to the voting Common Stock, par value $0.0001 per share, of the
Corporation (the "Voting Common Stock"), the non-voting Common Stock, par value
$0.0001 per share, of the Corporation (the "Non-Voting Common Stock" and
together with the Voting Common Stock, the "Common Stock") and all other
capital stock of the Corporation issued prior to or on or after the date hereof.

     (c)  The Corporation may issue fractions of shares of Series B Preferred
Stock.

     SECTION 2. DIVIDENDS

     (a)  Restricted Payments.  No dividend or distribution in cash, shares of
stock or other property on the Common Stock or other capital stock of the
Corporation shall be declared or paid or set apart for payment without the
unanimous approval of the Board of Directors and unless all accumulated and
unpaid dividends on the Series B Preferred Stock have been declared and paid.

     (b)  Payment of Dividends.  The holders of shares of Series B Preferred
Stock, on a pari passu basis with the Series A Preferred Stock, and in
preference to the holders of shares of Common Stock and of any shares of other
capital stock of the Corporation as to payment of dividends, shall be entitled
to receive, when, as and if declared by the Board of Directors, out of the
assets of the Corporation legally available therefor and subject to any
restrictions contained in the Indenture, cumulative dividends at an annual rate
equal to 6.50% of the Liquidation Preference from and after the respective
dates of issuance of applicable shares of Series B Preferred Stock (the "Issue
Date"), as long as the shares of Series B Preferred Stock remain outstanding.
Dividends shall be (i) computed on the basis of the Liquidation Preference;
(ii) accrue and be payable semi-annually, in arrears, on the last Business Day
of June and December in each year (each such date being referred to herein as a
"Semi-Annual Dividend Payment Date"), commencing on the first Semi-Annual
Dividend Payment Date following the Issue Date; and (iii) (X) with respect to
dividends paid on or prior to the second anniversary of the Issue Date, payable
in additional shares of Series B Preferred Stock valued as if the Second
Closing had already occurred unless and until such time as the Company shall
have made any payment or issued any shares pursuant to Section 7.4 of the
Securities Purchase Agreement, after which time such dividends will be valued
as if the Second Closing had not occurred and (Y) with respect to dividends
paid after the second anniversary of the Issue Date, payable in cash.
Notwithstanding anything in the foregoing to the contrary, if, during any
calendar year, a dividend is paid with respect to the number of shares of
Non-Voting Common Stock into which a share of Series B Preferred Stock is
convertible at the time such dividend is paid, which dividend, together with
all previous dividends paid during such year with respect to such number of
shares of Non-Voting Common Stock, exceeds the aggregate amount of dividends
paid to such date during such year with respect to a share of Series B
Preferred Stock (including amounts paid in such calendar year pursuant to this
sentence), then (x) the shares of the Series B Preferred Stock shall be
entitled to receive the amount of such excess at the time of the Non-Voting
Common Stock dividend and (y) any dividends otherwise payable on the Series B
Preferred Stock for the remainder of such calendar year shall be reduced (not
below zero) by the amount of the payment made pursuant to clause (x) above.

                                      -2-

<PAGE>
     (c)  Accrual of Dividends.  Dividends payable pursuant to clause (b) of
this Section 2 shall begin to accrue and be cumulative semi-annually from the
Issue Date, whether or not declared. The amount of dividends so payable shall be
determined on the basis of twelve 30-day months and a 360-day year. Accrued
dividends not paid on any Semi-Annual Dividend Payment Date shall accrue
additional dividends at an annual dividend rate of 6.50% of the Liquidation
Preference until paid in full. Dividends paid on the shares of Series B
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Directors may fix a record date for the determination of holders of shares of
Series B Preferred Stock entitled to receive payment of a dividend declared
thereon, which record date shall be no more than 60 days or less than 10 days
prior to the date fixed for the payment thereof.

     SECTION 3.  VOTING RIGHTS.

     (a)  Except as provided in this Section 3, no holder of Series B Preferred
Stock shall be entitled to vote such stock on any matter on which the
stockholders of the Corporation shall be entitled to vote, and shares of Series
B Preferred Stock shall not be included in determining the number of shares
voting or entitled to vote on any such matters; provided that the holders of
Series B Preferred Stock shall have the right to vote as a separate class on any
merger or consolidation of the Corporation with or into another entity or
entities, or any recapitalization or reorganization, in which shares of Series B
Preferred Stock would receive or be exchanged for the Shares of Series A
Preferred Stock or would otherwise be treated differently from shares of Series
A Preferred Stock in connection with such transaction, except that shares of
Series B Preferred Stock may, without such a separate class vote, receive or be
exchanged for non-voting securities which are otherwise identical on a per share
basis in amount and form to the voting securities received with respect to or
exchanged for the Series A Preferred Stock so long as (i) such non-voting
securities are convertible into such voting securities on the same terms as the
Series B Preferred Stock is convertible as the Series A Preferred Stock and (ii)
all other consideration is equal on a per share basis. Notwithstanding the
foregoing, holders of shares of the Series B Preferred Stock shall be entitled
to vote as a separate class on any amendment to this paragraph (b) of this
Section 3.

     (b)  Actions Not to be Taken Without Vote of Holders of Series B Preferred
Stock.  So long as any shares of Series B Preferred Stock issued pursuant to the
Securities Purchase Agreement are outstanding, the affirmative vote of the
holders of a majority of the shares of Series B Preferred Stock outstanding at
the time of such vote shall be required in order to:

          (i)  authorize, increase the authorized number of shares of, or issue
(including on conversion or exchange of any convertible or exchangeable
securities or by reclassification) any shares of any class or classes or series
within a class of the Corporation's capital stock ranking prior to (either as to
dividends or upon voluntary or involuntary liquidation, dissolution or winding
up), or pari passu with, the Series B Preferred Stock (other than as
contemplated herein);

                                      -3-
<PAGE>
          (ii)  increase the authorized number of shares of, or issue (including
on conversion or exchange of any convertible or exchangeable securities or by
reclassification) any shares of, Series B Preferred Stock other than as required
by this Certificate of Designation; or

          (iii)  authorize, adopt or approve an amendment to the Certificate of
Incorporation or this Certificate of Designation which would increase or
decrease the par value of the shares of Series B Preferred Stock, or alter or
change the powers, preferences or special rights of the Series B Preferred
Stock.

     (c)  Exercise of Voting Rights.  (i) The foregoing rights of holders of
shares of Series B Preferred Stock to take any actions as provided in this
Section 3 may be exercised at any annual meeting of stockholders or at a special
meeting of stockholders held for such purpose or at any adjournment thereof, or
by the written consent, delivered to the Secretary of the Corporation, of the
holders of a majority of all shares of Series B Preferred Stock outstanding as
of the record date of such written consent.

          So long as such right to vote continues, the Chairman of the Board of
the Corporation may call, and if the holders of Series B Preferred Stock are to
vote separately as a single class, upon the written request of holders of record
of 20% of the outstanding shares of Series B Preferred Stock, addressed to the
Secretary of the Corporation, at the principal office of the Corporation, the
Chairman of the Board of the Corporation shall call, a special meeting of the
holders of shares of Series B Preferred Stock entitled to vote as provided
herein. The Corporation shall use its best efforts to hold such meeting within
60, but in any event not later than 90, days after delivery of such request to
the Secretary, at the place and upon the notice provided by law and in the
By-Laws of the Corporation for the holding of meetings of stockholders; provided
that the Corporation shall not be required to call such a special meeting if
such request is received fewer than 90 days before the date fixed for the next
ensuing annual meeting of stockholders of the Corporation; and provided,
further, that if it is necessary for the Corporation to solicit proxies for use
at such special meeting, the Corporation's obligation to conduct such special
meeting shall be delayed for such period of time as is necessary for the
Corporation to prepare and file a proxy statement and to obtain the Commission's
clearance of such proxy statement.

          (ii)  At each meeting of stockholders at which the holders of shares
of Series B Preferred Stock shall have the right, voting separately as a single
class, to take any action, the presence in person or by proxy of the holders of
record of one-half of the total number of shares of Series B Preferred Stock
then outstanding and entitled to vote on the matter shall be necessary and
sufficient to constitute a quorum. At any such meeting or at any adjournment
thereof, in the absence of a quorum of the holders of shares of Series B
Preferred Stock, a majority of the holders of such shares present in person or
by proxy shall have the power to adjourn the meeting as to the actions to be
taken by the holders of shares of Series B Preferred Stock from time to time and
place to place without notice other than announcement at the meeting until a
quorum shall be present.

          (iii)  For the taking of any action as provided in clause (b) of this
Section 3 by the holders of shares of Series B Preferred Stock, each such holder
shall have one

                                      -4-
<PAGE>
vote for each share of such stock standing in his name on the transfer books of
the Corporation as of any record date fixed for such purpose or, if no such
date be fixed, at the close of business on the Business Day next preceding the
day on which notice is given, or if notice is waived, at the close of business
on the Business Day next preceding the day on which the meeting is held.

     SECTION 4. CERTAIN RESTRICTIONS.

     (a)  Dividends or Distributions.  Whenever any dividend payable on the
Series B Preferred Stock pursuant to Section 2 shall not have been paid in
full, whether in cash or in kind, the Corporation shall not declare or pay
dividends, or make any other distributions, on any shares of Parity Stock or
Junior Stock.

     (b)  Redemption and Purchase of Capital Stock. Whenever dividends on the
Series B Preferred Stock shall not have been paid in full, whether in cash or
in kind, the Corporation shall not redeem, purchase or otherwise acquire for
consideration any shares of Parity Stock or Junior Stock, other than (i)
pursuant to the exercise of outstanding options and warrants and (ii) the
repurchase of shares of capital stock or securities convertible into or
exchangeable for capital stock of the Corporation held by employees of the
Corporation upon the termination of their employment.

     (c)  Purchase of Capital Stock.  The Corporation shall not permit any
subsidiaries of the Corporation to purchase or otherwise acquire for
consideration any shares of capital stock of the Corporation unless the
Corporation could, pursuant to clause (b) of this Section 4, purchase such
shares at such time and in such manner.

     SECTION 5. REDEMPTION.

     (a)  Optional Redemption.  The Corporation shall, following the third
anniversary of the initial Issue Date, have the right, at its sole option and
election made in accordance with clause (b) below, to redeem all or any portion
of the then outstanding shares of Series B Preferred Stock for an amount per
share equal to the Liquidation Preference as of the date of the Redemption Date
(the "Redemption Price") if the Current Market Price per share of Common Stock
for at least 20 out of 30 consecutive Trading Days immediately preceding the
date of the Redemption Notice is equal to or greater than 150% of the
Conversion Price as of the first day of such 30-day period.

     (b)  Notice of Redemption.  Notice of any redemption of shares of Series B
Preferred Stock pursuant to clause (a) of this Section 5 shall be mailed, first
class postage prepaid, to each holder of shares of Series B Preferred Stock, at
such holder's address as it appears on the transfer books of the Corporation,
notifying such holder of the redemption to be effected, specifying (i) the
redemption date (the "Redemption Date") and (ii) the Redemption Price; and
calling upon such holder to surrender to the Corporation, in the manner and at
the place designated, such holder's certificate or certificates representing
the shares to be redeemed (the "Redemption Notice"). Each Redemption Notice
shall be mailed not less than 20 and not more than 30 days prior to the
proposed redemption date. The Redemption Date shall be determined

                                      -5-

<PAGE>
by the Company but in no event shall be earlier than the tenth day following
the date of the Redemption Notice or later than the thirtieth day following the
Redemption Notice.

     (c)  Payment of Redemption Price.  On the Redemption Date, the Corporation
shall wire transfer to an account designated by each holder the Redemption
Price for each of its shares of Series B Preferred Stock.

     (d)  Securities Purchase Agreement.  Any purchase or conversion effected
pursuant to Section 7.2 or Section 7.4 of the Securities Purchase Agreement by
the Purchaser (as defined in the Securities Purchase Agreement) or the
Corporation shall apply to all shares of Series B Preferred Stock (and, with
respect to a purchase, any shares convertible therefor), whether or not the
holder thereof is the Purchaser.

     SECTION 6. STATUS OF CONVERTED OR REDEEMED STOCK

     (a)  Status of Converted or Redeemed Stock.  Any shares of Series B
Preferred Stock converted, redeemed, purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and cancelled promptly
after the acquisition thereof. All such shares of Series B Preferred Stock
shall upon their cancellation, and upon the filing of any document required by
the DGCL, become authorized but unissued shares of Preferred Stock, $0.0001 par
value, of the Corporation and may be reissued as part of another series of
Preferred Stock, $0.0001 par value, of the Corporation.

     SECTION 7. LIQUIDATION, DISSOLUTION OR WINDING UP.

     (a)  (i)  If the Corporation shall (A) commence a voluntary case under the
Federal bankruptcy laws or any other applicable Federal or state bankruptcy,
insolvency or similar law, or (B) consent to the entry of an order for relief
in an involuntary case under such law or to the appointment of a receiver,
liquidator, assignee, custodian, trustee, sequestrator (or other similar
official) of the Corporation, or of any substantial part of its property, or
(C) make an assignment for the benefit of its creditors, or (D) admit in
writing its inability to pay its debts generally as they become due, or (ii)(x)
if a decree or order for relief in respect of the Corporation shall be entered
by a court having jurisdiction in the premises in an involuntary case under the
Federal bankruptcy laws or any other applicable Federal or state bankruptcy,
insolvency or similar law, or appointing a receiver, liquidator, assignee,
custodian, trustee, sequestrator (or other similar official) of the Corporation
or of any substantial part of its property, or ordering the winding up or
liquidation of its affairs, and (y) any such decree or order shall be unstayed
and in effect for a period of 60 consecutive days and on account of any such
event the Corporation shall liquidate, dissolve or wind up, or (iii) if the
Corporation shall otherwise liquidate, dissolve or wind up, after payment or
provision for the payment for the debts and other liabilities of the Corporation
(each, a "Liquidation"), no distribution shall be made to the holders of shares
of Junior Stock or Parity Stock unless, prior thereto, the holders of shares of
Series B Preferred Stock, subject to Section 8, shall have received the
Liquidation Preference with respect to each share held by holders of the Series
B Preferred Stock; provided, however, that, if the amount which would have been
paid upon any such Liquidation in respect of the aggregate number of shares of
Non-Voting Common Stock into which the Series B Preferred Stock is then
convertible.

                                      -6-

<PAGE>
divided by the number of shares of Series B Preferred Stock issued by the
Corporation and then outstanding, is greater than the Liquidation Preference
(without giving effect to any liquidation preference in favor of the holders of
Series B Preferred Stock), then the holders of Series B Preferred Stock shall be
entitled to receive in such Liquidation such greater amount for each share of
Series B Preferred Stock then issued and outstanding.

     (b)  If, upon any such Liquidation, whether voluntary or involuntary, the
assets to be distributed to the holders of the Series B Preferred Stock and the
Series A Preferred Stock shall be insufficient to permit payment of the full
amount of the Liquidation Preference with respect to each share of Series B
Preferred Stock and each share of Series A Preferred Stock and Series A
Preferred Stock, then the entire assets of the Corporation to be distributed
among the holders of the Series B Preferred Stock shall be distributed ratably
among such holders in accordance with the number of shares of Series B Preferred
Stock and Series A Preferred Stock held by each such holder in proportion to the
ratio that the Liquidation Preference payable on each such share bears to the
aggregate Liquidation Preference payable on all such shares.

     (c)  After the payment to the holders of shares of the Series B Preferred
Stock of the full amount of any liquidating distribution to which they are
entitled under this Article 7, the holders of the Series B Preferred Stock as
such shall have no right or claim to any of the remaining assets of the
Corporation.

     (d)  Whenever the distribution provided for in this Section 7 shall be
payable in securities or property other than cash, the value of such
distribution shall be the Fair Market Value of such securities or property.

     SECTION 8.  CONVERSION.

     (a)  Right to Convert.  Subject to the provisions for adjustment
hereinafter set forth, each share of Series B Preferred Stock shall be
convertible into such number of fully paid and nonassessable shares of
Non-Voting Common Stock as is determined by dividing the Liquidation Preference
as of the Conversion Date by the Conversion Price as of the Conversion Date. The
Conversion Price shall initially be $9.00 (the "Initial Conversion Price"), and
shall be increased to $10.00 at the Second Closing (or such other economically
equivalent amount reflecting any adjustment to the Conversion Price between the
Initial Closing and the Second Closing) and shall be further subject to
adjustment as provided in clauses (f) and (g) of this Section 8. The conversion
right set forth in this clause (a) shall be exercisable at the option of the
holder at any time following the initial Issue Date.

     (b)  Mechanics of Conversion.  Conversion of the Series B Preferred Stock
may be effected by any such holder upon the surrender to the Corporation at the
principal office of the Corporation in the State of New York or at the office of
any agent or agents of the Corporation, as may be designated by the Board of
Directors of the Corporation (the "Transfer Agent"), of the certificate(s) for
such Series B Preferred Stock to be converted, accompanied by a written notice
(the date of such notice being referred to as the "Conversion Date") stating
that such holder elects to convert all or a specified whole number of such
shares in accordance with the provisions of this Section 8 and specifying the
name or names in which such holder wishes the certificate or

                                      -7-
<PAGE>

certificates for shares of Non-Voting Common Stock to be issued. In case any
holder's notice shall specify a name or names other than that of such holder,
such notice shall be accompanied by payment of all transfer taxes payable upon
the issuance of shares of Non-Voting Common Stock in such name or names. Other
than such taxes, the Corporation will pay any and all transfer, issue, stamp
and other taxes (other than taxes based on income) that may be payable in
respect of any issue or delivery of shares of Non-Voting Common Stock on
conversion of Series B Preferred Stock pursuant hereto. As promptly as
practicable, and in any event within five Business Days after the surrender of
such certificate or certificates and the receipt of such notice relating
thereto and, if applicable, payment of all transfer taxes which are the
responsibility of the holder as set forth above (or the demonstration to the
satisfaction of the Corporation that such taxes have been paid), the
Corporation shall deliver or cause to be delivered (i) certificates
representing the number of validly issued, fully paid and nonassessable full
shares of Non-Voting Common Stock, to which the holder of shares of Series B
Preferred Stock being converted shall be entitled and (ii) if less than the
full number of shares of Series B Preferred Stock evidenced by the surrendered
certificate or certificates is being converted, a new certificate or
certificates, of like tenor, for the number of shares evidenced by such
surrendered certificate or certificates less the number of shares being
converted. Such conversion shall be deemed to have been made at the close of
business on the Conversion Date so that the rights of the holder thereof as to
the shares being converted shall cease except for the rights pursuant to
Section 8(c) to receive shares of Non-Voting Common Stock, in accordance
herewith, and the person entitled to receive the shares of Non-Voting Common
Stock shall be treated for all purposes as having become the record holder of
such shares of Non-Voting Common Stock at such time.

     In case any shares of Series B Preferred Stock are to be redeemed pursuant
to Section 5, such right of conversion shall cease and terminate as to the
shares of Series B Preferred Stock to be redeemed at the close of business on
the Business Day preceding the Redemption Date.

     (c)  Fractional Shares.  In connection with the conversion of any shares
of Series B Preferred Stock into Non-Voting Common Stock, no fractions of
shares of Non-Voting Common Stock shall be issued, but in lieu thereof the
Corporation shall pay a cash adjustment in respect of such fractional interest
in an amount equal to such fractional interest multiplied by the Current Market
Price per share of Non-Voting Common Stock on the Trading Day on which such
shares of Series B Preferred Stock are deemed to have been converted. If more
than one share of Series B Preferred Stock shall be surrendered for conversion
by the same holder at the same time, the number of full shares of Non-Voting
Common Stock issuable on conversion thereof shall be computed on the basis of
the total number of shares of Series B Preferred Stock so surrendered. Promptly
upon conversion, the Corporation shall pay to the holder of shares of Series B
Preferred Stock so converted out of funds legally available, an amount equal to
any accrued and unpaid dividends on the shares of Series B Preferred Stock
surrendered for conversion to the date of such conversion, together with cash
in lieu of any fractional interest of such holder.

     (d)  Reservation of Stock Issuable Upon Conversion.  The Corporation shall
at all times reserve and keep available for issuance upon the conversion of the
Series B Preferred Stock, free from any preemptive rights, such number of its
authorized but unissued shares of Non-Voting Common Stock as will from time to
time be sufficient to permit the conversion of all

                                      -8-

<PAGE>
outstanding shares of Series B Preferred Stock issued or issuable pursuant to
the Securities Purchase Agreement into Non-Voting Common Stock, and shall take
all actions required to increase the authorized number of shares of Non-Voting
Common Stock if necessary to permit the conversion of all outstanding shares of
Series B Preferred Stock.

     (e)  Initial Conversion Price.  The initial Conversion Price shall equal
$9.00 (the "Initial Conversion Price") (subject to adjustment from time to time
as provided in this Section 8).

     (f)  Adjustment to Conversion Price for Stock Dividends and for
Combinations or Subdivisions of Common Stock.  (i) In case the Corporation
shall at any time or from time to time after the Closing Date (A) pay a
dividend or make a distribution on the Outstanding shares of Common Stock in
shares of Common Stock, (B) subdivide the Outstanding shares of Common Stock,
(C) combine the Outstanding shares of Common Stock into a smaller number of
shares or (D) issue by reclassification of the shares of Common Stock any
shares of capital stock of the Corporation, then, and in each such case, the
Conversion Price in effect immediately prior to such event or the record date
therefor, whichever is earlier, shall be adjusted so that the holder of any
shares of Series B Preferred Stock thereafter surrendered for conversion into
Non-Voting Common Stock shall be entitled to receive the number of shares of
Non-Voting Common Stock or other securities of the Corporation which such
holder would have owned or have been entitled to receive after the happening of
any of the events described above, had such shares of Series B Preferred Stock
been surrendered for conversion immediately prior to the happening of such
event or the record date therefor, whichever is earlier. An adjustment made
pursuant to this clause (i) shall become effective (x) in the case of any such
dividend or distribution, on the date of such dividend or distribution
retroactive to immediately after the close of business on the record date for
the determination of holders of shares of Common Stock entitled to receive such
dividend or distribution, or (y) in the case of such subdivision,
reclassification or combination, at the close of business on the day upon which
such corporate action becomes effective. No adjustment shall be made pursuant to
this clause (i) in connection with any transaction to which clause (g) applies.

          (ii)  In case the Corporation shall issue shares of Common Stock (or
rights, warrants or other securities convertible into or exchangeable for
shares of Common Stock) (collectively, "Additional Shares") after the Closing
Date at a price per share (or having a conversion price per share) less than
the Conversion Price as of the date of issuance of such shares (or, in the case
of convertible or exchangeable securities, less than the Conversion Price as of
the date of issuance of the rights, warrants or other securities in respect of
which shares of Common Stock were issued), then, and in each such case, the
Conversion Price shall be reduced to an amount determined by multiplying
(A) the Conversion Price in effect on the day immediately prior to such date by
(B) a fraction, the numerator of which shall be the sum of (1) the number of
shares of Common Stock Outstanding immediately prior to such sale or issue
multiplied by the then applicable Conversion Price per share (the "Adjustment
Price") and (2) the aggregate consideration receivable by the Corporation for
the total number of shares of Common Stock so issued (or into or for which the
rights, warrants or other convertible securities may convert or be
exercisable), and the denominator of which shall be the sum of (x) the total
number of shares of Common Stock Outstanding immediately prior to such sale or
issue and (y) the number of Additional Shares issued (or into or for which the
rights, warrants or convertible securities may be converted or exercised),
multiplied by the Adjustment Price. An adjustment made pursuant to this

                                      -9-

<PAGE>

clause (ii) shall be made on the next Business Day following the date on which
any such issuance is made and shall be effective retroactively to the close of
business on the date of such issuance. For purposes of this clause (ii), the
aggregate consideration receivable by the Corporation in connection with the
issuance of shares of Common Stock or of rights, warrants or other securities
convertible into shares of Common Stock shall be deemed to be equal to the sum
of the aggregate offering price (before deduction of underwriting discounts or
commissions and expenses payable to third parties) of all such Common Stock,
rights, warrants and convertible securities plus the aggregate amount (as
determined on the date of issuance), if any, payable upon exercise or conversion
of any such rights, warrants and convertible securities into shares of Common
Stock. If, subsequent to the date of issuance of such right, warrants or other
convertible securities, the exercise or conversion price thereof is reduced,
such aggregate amount shall be recalculated and the Conversion Price shall be
adjusted retroactively to give effect to such reduction. On the expiration of
any option or the termination of any right to convert or exchange any securities
into Additional Shares, the Conversion Price then in effect hereunder shall
forthwith be increased to the Conversion Price which would have been in effect
at the time of such expiration or termination (but taking into account other
adjustments made following the time of issuance of such options or securities)
had such option or security, to the extent outstanding immediately prior to such
expiration or termination, never been issued. If Common Stock is sold as a unit
with other securities, the aggregate consideration received for such Common
Stock shall be deemed to be net of the Fair Market Value of such other
securities. The issuance or reissuance of (i) any shares of Common Stock or
rights, warrants or other securities convertible into shares of Common Stock
(whether treasury, shares or newly, issued shares), (A) pursuant to a dividend
or distribution on, or subdivision, combination or reclassification of, the
Outstanding shares of Common Stock requiring an adjustment in the Conversion
Price pursuant to clause (i) of this clause (f); (B) pursuant to any restricted
stock or stock option plan or program of the Corporation involving the grant of
options or rights to acquire Common Stock to directors, officers and employees
of the Corporation and its Subsidiaries so long as the granting of such options
or rights has been approved by the full Board of Directors or a committee of the
Board of Directors on which a director designated by a majority of the holders
of the Series A Preferred Stock is a member; (C) pursuant to any option,
warrant, right, or convertible security outstanding as of the Closing Date, or
(ii) the Series B Preferred Stock, the Series A Preferred Stock, Warrants and
any shares of Common Stock issuable upon conversion or exercise thereof shall
not be deemed to constitute an issuance of Common Stock or convertible
securities by the Corporation to which this clause (ii) applies. No adjustment
shall be made pursuant to this clause (ii) in connection with any transaction to
which clause (g) applies.

          (iii)  The term "dividend," as used in this clause (f), shall mean a
dividend or other distribution upon the capital stock of the Corporation.

          (iv)  Anything in this clause (f) to the contrary notwithstanding,
the Corporation shall not be required to give effect to any adjustment in the
Conversion Price (x) if, in connection with any event which would otherwise
require an adjustment pursuant to this clause (f), the holders of Series B
Preferred Stock have received the dividend or distribution to which such
holders are entitled under Section 2 hereof or (y) unless and until the net
effect of one or more adjustments (each of which shall be carried forward),
determined as above provided, shall have resulted in a change of the Conversion
Price such that the number of shares of Non-Voting

                                      -10-

<PAGE>
Common Stock receivable upon conversion of each share of Series B Preferred
Stock would differ by at least one one-hundredth of one share of Non-Voting
Common Stock, and when the cumulative net effect of more than one adjustment so
determined shall be to change the Conversion Price by at least one one-hundredth
of one share of Non-Voting Common Stock, such change in Conversion Price shall
thereupon be given effect.

          (v)  The certificate of any firm of independent public accountants of
recognized national standing selected by the Board of Directors of the
Corporation (which may be the firm of independent public accountants regularly
employed by the Corporation) shall be presumptively correct for any computation
made under this clause (f).

          (vi)  If the Corporation shall take a record of the holders of its
Common Stock for the purpose of entitling them to receive a dividend or other
distribution, and shall thereafter and before the distribution to stockholders
thereof legally abandon its plan to pay or deliver such dividend or
distribution, then thereafter no adjustment in the number of shares of Common
Stock issuable upon exercise of the right of conversion granted by this
clause (f) or in the Conversion Price then in effect shall be required by
reason of the taking of such record.

     (g)  Adjustment to Conversion Price for Reclassification and
Reorganization. In the case of any consolidation or merger of the Corporation
with or into another corporation (a "Transaction") occurring at any time, each
share of Series B Preferred Stock then outstanding shall thereafter be
convertible into, in lieu of the Non-Voting Common Stock issuable upon such
conversion prior to consummation of such Transaction, the kind and amount of
shares of stock and other securities and property receivable (including cash)
upon the consummation of such Transaction by a holder of that number of shares
of Non-Voting Common Stock into which one share of Series B Preferred Stock was
convertible immediately prior to such Transaction. In case securities or
property other than Non-Voting Common Stock shall be issuable or deliverable
upon conversion as aforesaid, then all references in this Section 8 shall be
deemed to apply, so far as appropriate and nearly as may be, to such other
securities or property.

     (h)  Notice of Record Date. In case at any time or from time to time (i)
the Corporation shall pay any stock dividend or make any other non-cash
distribution to the holders of its Common Stock, or offer for subscription pro
rata to the holders of its Common Stock any additional shares of stock of any
class or any other right, or (ii) there shall be any capital reorganization or
reclassification of the Common Stock of the Corporation or consolidation or
merger of the Corporation with or into another corporation, or any sale or
conveyance to another corporation of the property of the Corporation as an
entirety or substantially as an entirety, or (iii) there shall be a voluntary
or involuntary dissolution, liquidation or winding up of the Corporation, then,
in any one of more of said cases the Corporation shall give at least 20 days'
prior written notice (the time of mailing of such notice shall be deemed to be
the time of giving thereof) to the registered holders of the Series B
Preferred Stock at the addresses of each as shown on the books of the
Corporation maintained by the Transfer Agent thereof of the date on which (A)
a record shall be taken for such stock dividend, distribution or subscription
rights or (B) such reorganization, reclassification, consolidation, merger,
sale or conveyance, dissolution, liquidation or winding up shall take place, as
the case may be; provided that, in the case of any Transaction to which clause
(g) applies the Corporation shall give at least 30 days' prior written notice as

                                      -11-
<PAGE>
aforesaid. Such notice shall also specify the date as of which the holders of
the Common Stock of record shall participate in said dividend, distribution or
subscription rights or shall be entitled to exchange their Common Stock for
securities or other property deliverable upon such reorganization,
reclassification, consolidation, merger, sale or conveyance or participate in
such dissolution, liquidation or winding up, as the case may be. Failure to give
such notice shall not invalidate any action so taken.

     (i)  Conversion into Series A Preferred Stock.  In addition to the other
provisions of this Section 8, the holders of Series B Preferred Stock shall be
entitled to convert their shares of Series B Preferred Stock into shares of
Series A Preferred Stock under the identical terms, procedures and restrictions
as a holder of shares of Non-Voting Common Stock may convert such shares into
shares of Voting Common Stock, except that for purposes of this Certificate, the
term "Regulated Stockholder" shall also include International Motor Cars Group
II, LLC, Chase Equity Associates, L.P. or any other stockholder (x) that is
subject to the provisions of Regulation Y and (y) that holds shares of Common
Stock or Preferred Stock of the Corporation.

     SECTION 9.  REPORTS AS TO ADJUSTMENTS.

     Upon any adjustment of the Conversion Price then in effect and any increase
or decrease in the number of shares of Non-Voting Common Stock issuable upon the
operation of the conversion provisions set forth in Section 8, then, and in each
such case, the Corporation shall promptly deliver to the Transfer Agent of the
Series B Preferred Stock and Non-Voting Common Stock, a certificate signed by
the President or a Vice President and by the Treasurer or an Assistant Treasurer
or the Secretary or an Assistant Secretary of the Corporation, setting forth in
reasonable detail the event requiring the adjustment and the method by which
such adjustment was calculated and specifying the Conversion Price then in
effect following such adjustment and the increased or decreased number of shares
issuable upon a conversion following such adjustment, and shall set forth in
reasonable detail the method of calculation of each and a brief statement of the
facts requiring such adjustment. Where appropriate, such notice to holders of
the Series B Preferred Stock may be given in advance and included as part of the
notice required under the provisions of Section 8(h).

     SECTION 10.  CERTAIN COVENANTS.

     Any registered holder of Series B Preferred Stock may proceed to protect
and enforce its rights and the rights of such holders by any available remedy by
proceeding at law or in equity to protect and enforce any such rights, whether
for the specific enforcement of any provision in this Certificate of Designation
or in aid of the exercise of any power granted herein, or to enforce any other
proper remedy.
