     such subscription, by (ii) the Initial Exercise Price, and such holder
     shall thereupon be entitled to receive the number of duly authorized,

      notice (without giving effect to any adjustment thereof pursuant to
      Section 4 or 5 hereof) multiplied by (y) the Current Market Price of each
      such share of Class L Common Stock (or such Other Securities) so
      receivable upon such exercise

         over

         (ii) (x) the number of shares of Class L Common Stock (without giving

   herein to the exercise of this Warrant shall be deemed to include a reference
   to the conversion of this Warrant into Class L Common Stock (or Other
   Securities) in accordance with the terms of this Section 2.1.2.

     2.2. When Exercise Effective. Each exercise of this Warrant shall be deemed
          -----------------------
to have been effected immediately prior to the close of business on the business
day on which this Warrant shall have been surrendered to the Company as provided
in Section 2.1 hereof, and at such time the Person or Persons in whose name or
names any certificate or certificates for shares of Class L Common Stock (or
Other Securities) shall be issuable upon such exercise as provided in Section
2.3 hereof shall be deemed to have become the holder or holders of record
thereof.

     2.3. Delivery of Stock Certificates, etc. As soon as practicable after each
          -----------------------------------
exercise of this Warrant, in whole or in part, the Company at its expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to the holder hereof or, subject to the
provisions of the Stockholders Agreement, as such holder (upon payment by such
holder of any applicable transfer taxes) may direct:

     (a)  a certificate or certificates for the number of duly authorized,
   validly issued, fully paid and nonassessable shares of Class L Common Stock
   (or Other Securities) to which such holder shall be entitled upon such
   exercise plus, in lieu of any fractional share to which such holder would
   otherwise be entitled, cash in an amount equal to the same fraction of the
   current Market Price per share on the business day next preceding the date of
   such exercise; and

     (b)  in case such exercise is in part only, a new Warrant or Warrants of
   like tenor, dated the date hereof and calling in the aggregate on the face or
   faces thereof for the number of shares of Class L Common Stock equal (without
   giving effect to any adjustment thereof pursuant to the terms hereof) to the
   number of such shares called for on the face of this Warrant minus the number
   of such shares designated by the holder upon such exercise as provided in
   Section 2.1 hereof.

     2.4. Exchange of Warrant. This Warrant is exchangeable at the aforesaid
          -------------------
principal office of the Company for Warrants for the purchase of the same
aggregate number of shares of Class L Common Stock, each new Warrant to
represent the right to purchase such number of shares of Class L Common Stock as
the holder hereof shall designate at the time of such exchange. All Warrants
issued on transfers or exchanges shall be dated the date hereof and shall be
identical with this Warrant except as to the number of shares of Class L Common
Stock issuable pursuant hereto.

     2.5. Company to Reaffirm Obligations. The Company will, at the time of or
          -------------------------------
at any time after each exercise of this Warrant, upon the request of the holder
hereof, acknowledge in writing its continuing obligation to afford to such
holder all rights to which such holder shall continue to

                                      -3-
<PAGE>

be entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligation of the Company to afford such
rights to such holder.

3. Stock Fully Paid; Reservation of Shares.  The Company represents, warrants,
   ---------------------------------------
covenants and agrees that all shares of Class L Common Stock which may be issued
upon the exercise of the rights represented by this Warrant will, upon issuance,
be duly authorized, validly issued, fully paid and non-assessable.  The Company
further covenants and agrees that during the period within which the rights
represented by this Warrant may be exercised, the Company will at all times have
authorized and reserved solely for the purpose of the issuance upon exercise of
this Warrant a sufficient number of shares of Class L Common Stock to provide
for the exercise of the rights represented by this Warrant.

   If any shares of Class L Common Stock required to be reserved for issuance
upon exercise of this Warrant require registration or qualification with any
governmental authority under any federal or state law before such shares may be
so issued, the Company will in good faith and as expeditiously as reasonably
possible use reasonable efforts to cause such shares to be duly registered or
qualified; provided, however, that the Company shall not be required to effect
           --------  -------
any registration under federal or state securities laws other than as provided
in Section 7 of the Stockholders Agreement.

   The Company will (a) not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the amount payable therefor
upon such exercise immediately prior to such increase in par value, (b) take all
such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock
upon the exercise of this Warrant, and (c) use its reasonable efforts to obtain
all such authorizations, exemptions or consents from any public regulatory body
having jurisdiction thereof as may be necessary to enable the Company to perform
its obligations under this Warrant; provided, however, that the Company shall
                                    --------  -------
not be required to effect any registration under federal or state securities
laws other than as provided in Section 6 of the Stockholders Agreement.

4. Adjustment of Number of Shares Purchasable Upon Exercise.  The number of
   --------------------------------------------------------
shares of Class L Common Stock purchasable upon the exercise of this Warrant and
the payment of the Initial Exercise Price shall be determined by multiplying the
number of shares of Class L Common Stock which would otherwise (but for the
provisions of this Section 4) be issuable upon such exercise, as designated by
the holder hereof pursuant to Section 2.1 hereof, by a fraction (a) the
numerator of which shall be the Initial Exercise Price and (b) the denominator
of which shall be the Exercise Price in effect on the date of such exercise.
The "Exercise Price" shall initially be the Initial Exercise Price and shall be
adjusted and readjusted from time to time as provided in this Section 4 and, as
so adjusted or readjusted, shall remain in effect until a further adjustment or
readjustment thereof is required by this Section 4.

                                      -4-
<PAGE>

     4.1. Subdivision or Combination of Shares. If the Company, at any time
          ------------------------------------
while this Warrant is outstanding, shall subdivide (by stock split or otherwise)
or combine (by consolidation or otherwise) any outstanding shares of Class L
Common Stock, the Exercise Price shall be (a) proportionately decreased, to the
nearest one hundredth of one cent, in the case of a subdivision of shares, to
reflect the increase in the total number of shares of Class L Common Stock
outstanding as a result of such subdivision or (b) proportionately increased, to
the nearest one hundredth of one cent, in the case of a combination of shares,
to reflect the decrease in the total number of shares of Class L Common Stock
outstanding as a result of such combination, as of the effective date of such
subdivision or combination, or if the Company shall take a record of holders of
Class L Common Stock for the purpose of so subdividing or combining, as of the
applicable record date, whichever is earlier.

     4.2. Certain Dividends. If the Company, at any time while this Warrant is
          -----------------
outstanding, shall pay any stock dividend on the Class L Common Stock, the
Exercise Price shall be adjusted, as of the date the Company shall take a record
of the holders of the Class L Common Stock, for the purpose of receiving such
dividend (or if no such record is taken, as of the date of such dividend), to
the nearest one hundredth of one cent, to the product obtained by multiplying
the Exercise Price in effect immediately prior to such stock dividend by a
fraction (a) the numerator of which shall be the total number of shares of the
Class L Common Stock outstanding immediately prior to such dividend and (b) the
denominator of which shall be the total number of shares of the Class L Common
Stock outstanding immediately after such dividend (plus in the event that the
Company paid cash for fractional shares, the number of additional shares which
would have been outstanding had the Company issued fractional shares in
connection with said dividends).

     4.3. Other Events. If any event occurs as to which the foregoing provisions
          ------------
of Section 4.1 and 4.2 are not strictly applicable or, if strictly applicable,
would not, in the good faith judgment of the Board, fairly and adequately
protect the purchase rights represented by the Warrants in accordance with the
essential intent and principles of such provisions, then the Board shall make
such adjustments in the application of such provisions, in accordance with such
essential intent and principles, as shall be reasonably necessary, in the good
faith opinion of the Board, to protect such purchase rights as aforesaid.

     4.4. Adjustment of Exercise Price. If at any time, as a result of any
          ----------------------------
adjustments hereunder, the sum of the Exercise Price plus a proportionate
portion of the consideration paid by the holder for this Warrant shall be less
than the par value per share of Class L Common Stock, then the price payable per
share of Class L Common Stock by the holder hereunder in the event of an
exercise of this Warrant, in whole or in part, shall be an amount equal to the
par value per share of the Class L Common Stock.

5. Adjustments for Consolidation, Merger, Sale of Assets, Reorganization, etc.
   --------------------------------------------------------------------------
In case the Company after the date hereof (a) shall consolidate with or merge
into any other Person and shall not be the continuing or surviving corporation
of such consolidation or merger, or (b) shall permit any other Person to
consolidate with or merge into the Company and the Company shall be the
continuing or surviving Person but, in connection with such consolidation or
merger, the Common

                                      -5-
<PAGE>

Stock or Other Securities shall be changed into or exchanged for stock or other
securities of any other Person or cash or any other property, or (c) shall
transfer all or substantially all of its properties or assets to any other
Person or (d) shall effect a capital reorganization or reclassification of the
Class L Common Stock or Other Securities, then, and in the case of each such
transaction, proper provision shall be made so that, upon the basis and the
terms and in the manner provided in this Warrant, the holder of this Warrant,
upon the exercise hereof at any time after the consummation of such transaction,
shall be entitled to receive (at the aggregate Exercise Price in effect at the
time of such consummation for all Class L Common Stock or Other Securities
issuable upon such exercise immediately prior to such consummation), in lieu of
the Class L Common Stock or Other Securities issuable upon such exercise prior
to such consummation, the greatest amount of securities, cash or other property
to which such holder would actually have been entitled as a shareholder upon
such consummation if such holder had exercised the rights represented by this
Warrant immediately prior thereto.

6. Notice  of Adjustments.  Whenever the Exercise Price is adjusted pursuant to
   ----------------------
Section 4 hereof, the Company will promptly deliver to the holder of this
Warrant at the address provided in the Stockholders Agreement a certificate
setting forth, in reasonable detail, the event that triggered the adjustment,
the amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the Board made any determination
hereunder), and the Exercise Price after giving effect to such adjustment.

7. Dividends/Distributions.  The Company shall give the Holder of this Warrant
   -----------------------
not less than 15 days prior written notice of its intent to pay a dividend or
make any other distribution on any shares of its capital stock and shall set
forth in such notice the amount and type of such dividend or distribution and
the share of capital stock on which such dividend or distribution will be paid.
If the Holder of this Warrant does not elect to exercise this Warrant prior to
such dividend or distribution, an amount equal to the cash which the Holder
would have received on the Class L Common Stock had the Holder exercised this
Warrant immediately prior to such dividend or distribution shall at the option
of the Holder (a) be used as a credit against the Exercise Price or (b) be
retained by the Company and paid to such Holder upon the exercise of this
Warrant.

8. Restrictions; Legends.

2.1.1. Exercise.  This Warrant may be exercised by the holder hereof, in whole

Warrant duly executed by such holder and accompanied by (a) wire transfer of
immediately available funds, (b) certified or official bank check payable to the
order of the Company or (c) delivery to the Company of a principal amount of
notes, in each case in the amount obtained by multiplying (i) the number of
shares of Class A-1 Common Stock (without giving effect to any adjustment
thereof pursuant to the provisions hereof) for which this Warrant is then being
exercised, as designated in such subscription, by (ii) the Initial Exercise
Price, and such holder shall thereupon be entitled to receive the number of duly

      holder would be entitled to receive upon exercise of this Warrant for the
      number of shares of Class A-1 Common Stock designated in such conversion
      notice (without giving effect to any adjustment thereof pursuant to
      Section 4 or 5 hereof) multiplied by (y) the Current Market Price of each
      such share of Class A-1 Common Stock (or such Other Securities) so
      receivable upon such exercise

         over

         (ii) (x) the number of shares of Class A-1 Common Stock (without giving
      effect to any adjustment thereof pursuant to the provisions hereof) for
      which this Warrant may be exercised, as designated in such conversion
      notice, multiplied by (y) the Initial Exercise Price

         divided by

                                      -2-
<PAGE>

     (b) such Current Market Price of each such share of Class A-1 Common Stock
   (or Other Securities).

   For all purposes of this Warrant (other than this Section 2.1), any reference
   herein to the exercise of this Warrant shall be deemed to include a reference
   to the conversion of this Warrant into Class A-1 Common Stock (or Other
   Securities) in accordance with the terms of this Section 2.1.2.

2.2.  When Exercise Effective.  Each exercise of this Warrant shall be deemed to
      -----------------------
have been effected immediately prior to the close of business on the business
day on which this Warrant shall have been surrendered to the Company as provided
in Section 2.1 hereof, and at such time the Person or Persons in whose name or
names any certificate or certificates for shares of Class A-1 Common Stock (or
Other Securities) shall be issuable upon such exercise as provided in Section
2.3 hereof shall be deemed to have become the holder or holders of record
thereof.

2.3.  Delivery of Stock Certificates, etc.  As soon as practicable after each
      -----------------------------------
exercise of this Warrant, in whole or in part, the Company at its expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to the holder hereof or, subject to the
provisions of the Stockholders Agreement, as such holder (upon payment by such
holder of any applicable transfer taxes) may direct:

     (a)  a certificate or certificates for the number of duly authorized,
   validly issued, fully paid and nonassessable shares of Class A-1 Common Stock
   (or Other Securities) to which such holder shall be entitled upon such
   exercise plus, in lieu of any fractional share to which such holder would
   otherwise be entitled, cash in an amount equal to the same fraction of the
   current Market Price per share on the business day next preceding the date of
   such exercise; and

     (b)  in case such exercise is in part only, a new Warrant or Warrants of
   like tenor, dated the date hereof and calling in the aggregate on the face or
   faces thereof for the number of shares of Class A-1 Common Stock equal
   (without giving effect to any adjustment thereof pursuant to the terms
   hereof) to the number of such shares called for on the face of this Warrant
   minus the number of such shares designated by the holder upon such exercise
   as provided in Section 2.1 hereof.

2.4.  Exchange of Warrant.  This Warrant is exchangeable at the aforesaid
      -------------------
principal office of the Company for Warrants for the purchase of the same
aggregate number of shares of Class A-1 Common Stock, each new Warrant to
represent the right to purchase such number of shares of Class A-1 Common Stock
as the holder hereof shall designate at the time of such exchange.  All Warrants
issued on transfers or exchanges shall be dated the date hereof and shall be
identical with this Warrant except as to the number of shares of Class A-1
Common Stock issuable pursuant hereto.

2.5.  Company to Reaffirm Obligations.  The Company will, at the time of or at
      -------------------------------
any time after each exercise of this Warrant, upon the request of the holder
hereof, acknowledge in writing

                                      -3-
<PAGE>

its continuing obligation to afford to such holder all rights to which such
holder shall continue to be entitled after such exercise in accordance with the
terms of this Warrant, provided that if any such holder shall fail to make any
such request, the failure shall not affect the continuing obligation of the
Company to afford such rights to such holder.

3. Stock Fully Paid; Reservation of Shares.  The Company represents, warrants,
   ---------------------------------------
covenants and agrees that all shares of Class A-1 Common Stock which may be
issued upon the exercise of the rights represented by this Warrant will, upon
issuance, be duly authorized, validly issued, fully paid and non-assessable.
The Company further covenants and agrees that during the period within which the
rights represented by this Warrant may be exercised, the Company will at all
times have authorized and reserved solely for the purpose of the issuance upon
exercise of this Warrant a sufficient number of shares of Class A-1 Common Stock
to provide for the exercise of the rights represented by this Warrant.

   If any shares of Class A-1 Common Stock required to be reserved for issuance
upon exercise of this Warrant require registration or qualification with any
governmental authority under any federal or state law before such shares may be
so issued, the Company will in good faith and as expeditiously as reasonably
possible use reasonable efforts to cause such shares to be duly registered or
qualified; provided, however, that the Company shall not be required to effect
any registration under federal or state securities laws other than as provided
in Section 7 of the Stockholders Agreement.

   The Company will (a) not increase the par value of any shares of Common Stock
receivable upon the exercise of this Warrant above the amount payable therefor
upon such exercise immediately prior to such increase in par value, (b) take all
such action as may be necessary or appropriate in order that the Company may
validly and legally issue fully paid and nonassessable shares of Common Stock
upon the exercise of this Warrant, and (c) use its reasonable efforts to obtain
all such authorizations, exemptions or consents from any public regulatory body
having jurisdiction thereof as may be necessary to enable the Company to perform
its obligations under this Warrant; provided, however, that the Company shall
not be required to effect any registration under federal or state securities
laws other than as provided in Section 6 of the Stockholders Agreement.

4. Adjustment of Number of Shares Purchasable Upon Exercise.  The number of
   --------------------------------------------------------
shares of Class A-1 Common Stock purchasable upon the exercise of this Warrant
and the payment of the Initial Exercise Price shall be determined by multiplying
the number of shares of Class A-1 Common Stock which would otherwise (but for
the provisions of this Section 4) be issuable upon such exercise, as designated
by the holder hereof pursuant to Section 2.1 hereof, by a fraction (a) the
numerator of which shall be the Initial Exercise Price and (b) the denominator
of which shall be the Exercise Price in effect on the date of such exercise.
The "Exercise Price" shall initially be the Initial Exercise Price and shall be
adjusted and readjusted from time to time as provided in this Section 4 and, as
so adjusted or readjusted, shall remain in effect until a further adjustment or
readjustment thereof is required by this Section 4.

                                      -4-
<PAGE>

4.1.  Subdivision or Combination of Shares.  If the Company, at any time while
      ------------------------------------
this Warrant is outstanding, shall subdivide (by stock split or otherwise) or
combine (by consolidation or otherwise) any outstanding shares of Class A-1
Common Stock, the Exercise Price shall be (a) proportionately decreased, to the
nearest one hundredth of one cent, in the case of a subdivision of shares, to
reflect the increase in the total number of shares of Class A-1 Common Stock
outstanding as a result of such subdivision or (b) proportionately increased, to
the nearest one hundredth of one cent, in the case of a combination of shares,
to reflect the decrease in the total number of shares of Class A-1 Common Stock
outstanding as a result of such combination, as of the effective date of such
subdivision or combination, or if the Company shall take a record of holders of
Class A-1 Common Stock for the purpose of so subdividing or combining, as of the
applicable record date, whichever is earlier.

4.2.  Certain Dividends.  If the Company, at any time while this Warrant is
      -----------------
outstanding, shall pay any stock dividend on the Class A-1 Common Stock, the
Exercise Price shall be adjusted, as of the date the Company shall take a record
of the holders of the Class A-1 Common Stock, for the purpose of receiving such
dividend (or if no such record is taken, as of the date of such dividend), to
the nearest one hundredth of one cent, to the product obtained by multiplying
the Exercise Price in effect immediately prior to such stock dividend by a
fraction (a) the numerator of which shall be the total number of shares of the
Class A-1 Common Stock outstanding immediately prior to such dividend and (b)
the denominator of which shall be the total number of shares of the Class A-1
Common Stock outstanding immediately after such dividend (plus in the event that
the Company paid cash for fractional shares, the number of additional shares
which would have been outstanding had the Company issued fractional shares in
connection with said dividends).

4.3.  Other Events.  If any event occurs as to which the foregoing provisions of
      ------------
Section 4.1 and 4.2 are not strictly applicable or, if strictly applicable,
would not, in the good faith judgment of the Board, fairly and adequately
protect the purchase rights represented by the Warrants in accordance with the
essential intent and principles of such provisions, then the Board shall make
such adjustments in the application of such provisions, in accordance with such
essential intent and principles, as shall be reasonably necessary, in the good
faith opinion of the Board, to protect such purchase rights as aforesaid.

4.4.  Adjustment of Exercise Price.  If at any time, as a result of any
      ----------------------------
adjustments hereunder, the sum of the Exercise Price plus a proportionate
portion of the consideration paid by the holder for this Warrant shall be less
than the par value per share of Class A-1 Common Stock, then the price payable
per share of Class A-1 Common Stock by the holder hereunder in the event of an
exercise of this Warrant, in whole or in part, shall be an amount equal to the
par value per share of the Class A-1 Common Stock.

5. Adjustments for Consolidation, Merger, Sale of Assets, Reorganization, etc.
   --------------------------------------------------------------------------
In case the Company after the date hereof (a) shall consolidate with or merge
into any other Person and shall not be the continuing or surviving corporation
of such consolidation or merger, or (b) shall permit any other Person to
consolidate with or merge into the Company and the Company shall be the
continuing or surviving Person but, in connection with such consolidation or
merger, the Common

                                      -5-
<PAGE>

Stock or Other Securities shall be changed into or exchanged for stock or other
securities of any other Person or cash or any other property, or (c) shall
transfer all or substantially all of its properties or assets to any other
Person or (d) shall effect a capital reorganization or reclassification of the
Class A-1 Common Stock or Other Securities, then, and in the case of each such
transaction, proper provision shall be made so that, upon the basis and the
terms and in the manner provided in this Warrant, the holder of this Warrant,
upon the exercise hereof at any time after the consummation of such transaction,
shall be entitled to receive (at the aggregate Exercise Price in effect at the
time of such consummation for all Class A-1 Common Stock or Other Securities
issuable upon such exercise immediately prior to such consummation), in lieu of
the Class A-1 Common Stock or Other Securities issuable upon such exercise prior
to such consummation, the greatest amount of securities, cash or other property
to which such holder would actually have been entitled as a shareholder upon
such consummation if such holder had exercised the rights represented by this
Warrant immediately prior thereto.

6. Notice  of Adjustments.  Whenever the Exercise Price is adjusted pursuant to
   ----------------------
Section 4 hereof, the Company will promptly deliver to the holder of this
Warrant at the address provided in the Stockholders Agreement a certificate
setting forth, in reasonable detail, the event that triggered the adjustment,
the amount of the adjustment, the method by which such adjustment was calculated
(including a description of the basis on which the Board made any determination
hereunder), and the Exercise Price after giving effect to such adjustment.

7. Dividends/Distributions.  The Company shall give the Holder of this Warrant
   -----------------------
not less than 15 days prior written notice of its intent to pay a dividend or
make any other distribution on any shares of its capital stock and shall set
forth in such notice the amount and type of such dividend or distribution and
the share of capital stock on which such dividend or distribution will be paid.
If the Holder of this Warrant does not elect to exercise this Warrant prior to
such dividend or distribution, an amount equal to the cash which the Holder
would have received on the Class A-1 Common Stock had the Holder exercised this
Warrant immediately prior to such dividend or distribution shall at the option
of the Holder (a) be used as a credit against the Exercise Price or (b) be
retained by the Company and paid to such Holder upon the exercise of this
Warrant.

such time as this Warrant or any such shares of Class A-1 Common Stock shall no
longer be subject to the provisions of Section 9 of the Stockholders Agreement.

Class A-1 Common Stock, the holder thereof shall be entitled to receive from the
Company, without expense (other than applicable transfer taxes, if any), new
certificates not bearing the applicable legends required by Section 8.1 hereof.

9. No Rights or Liabilities as Stockholder.  Nothing contained in this Warrant
   ---------------------------------------
shall be construed as conferring upon the holder hereof any rights as a
