     which the Initial Investors realize on the shares of Class A Common Stock,
     Class C Common Stock and Class D Common Stock (or Common Stock issued upon
     conversion thereof) sold by the Initial Investors in such Approved Sale an
     amount in cash greater than the product of 2 multiplied by the Initial
     Investors Investment and such amount represents a forty percent (40%)
     annual return on the Initial Investors Investment, compounded from the date
     hereof to the closing date of such Approved Sale;

         (ii)   immediately prior to the closing of an Approved Sale that (A) is
     prior to the closing of the Initial Public Offering and (B) is approved by
     less than a Supermajority Vote of the Board and such approval occurs on a
     date prior to the first anniversary of the date hereof; or

         (iii)  if an Initial Public Offering has occurred, 90 days following
     the closing of a transaction or the last of a series of transactions that
     results in the Initial Investors having disposed of 50% of the shares of
     Class A Common Stock, Class C Common Stock and Class D Common Stock owned
     by them as of the date hereof (or Common Stock issued upon conversion
     thereof) (an "Initial Investors Cash-Out") and as a result of such
                   --------------------------
     transaction or the last of such series of transactions, the Initial
     Investors have realized in cash an amount greater than the product of 1.5
     multiplied by the Initial Investors Investment and such amount, together
     with the amount the Initial Investors could realize in the public sale of
     the remaining shares owned by the Initial Investors as of the date hereof,
     represents a forty percent (40%) annual return on the Initial Investors
     Investment, compounded from the date hereof to the date 90 days following

                                       4
<PAGE>

     Initial Investors Cash-Out. The amount that could be realized by the
     Initial Investors in the public sale of such remaining shares shall be
     deemed to be an amount per share equal to the average closing sale price of
     the Common Stock as traded on the New York Stock Exchange or American Stock
     Exchange or as reported on the Nasdaq National Market over the 90-day
     period following the date of the Initial Investors Cash-Out.

     which the Initial Investors realize on the shares of Class A Common Stock,
     Class C Common Stock and Class D Common Stock (or Common Stock issued upon
     conversion thereof) sold by the Initial Investors in such Approved Sale an
     amount in cash greater than the product of 3 multiplied by the Initial
     Investors Investment and such amount represents a sixty percent (60%)
     annual return on the Initial Investors Investment, compounded from the date
     hereof to the closing date of such Approved Sale;

         (ii)   immediately prior to the closing of an Approved Sale that (A) is
     prior to the closing of the Initial Public Offering and (B) is approved by
     less than a Supermajority Vote of the Board and such approval occurs on a
     date prior to the first anniversary of the date hereof; or

         (iii)  if an Initial Public Offering has occurred, 90 days following an
     Initial Investors Cash-Out and as a result of such transaction or the last
     of such series of transactions, the Initial Investors have realized in cash
     an amount greater than the product of 3 multiplied by the Initial Investors
     Investment and such amount, together with the amount the Initial Investors
     could realize in the public sale of the remaining shares owned by the
     Initial Investors as of the date hereof, represents a sixty percent (60%)
     annual return on the Initial Investors Investment, compounded from the date
     hereof to the date 90 days following the date of the Initial Investors
     Cash-Out.  The amount that could be realized by the Initial Investors in
     the public sale of such remaining shares shall be deemed to be an amount
     per share equal to the average closing sale price of the Common Stock as
     traded on the New York Stock Exchange or American Stock Exchange or as
     reported on the Nasdaq National Market over the 90-day period following the
     date of the Initial Investors Cash-Out.

     (c) Holdings shall give to the Holder written notice (the "Holdings
                                                                --------
Notice") of the occurrence of an Approved Sale at least 20 days prior to the
------
anticipated closing of such Approved Sale or an Initial Investors Cash-Out
within 100 days following such Initial Investors Cash-Out.

     (d) If the event giving rise to the Holdings Notice is an anticipated
Approved Sale, the Holdings Notice shall state:  (i) the anticipated date of
closing of the Approved Sale, (ii) whether or not Holdings anticipates that the
Approved Sale will cause the vesting of the 40%

                                       5
<PAGE>

IRR Warrant or the 60% IRR Warrant and (iii) that certificates for the Warrant
Shares (or such other shares or consideration that may be received by a holder
of Warrant Shares upon the closing of such Approved Sale) will be delivered to
the Holder on the closing date of such Approved Sale, subject to the vesting of
such warrants, at the principal office of Holdings or such other place as may be
designated by Holdings in the Holdings Notice.

     (e) If the event giving rise to the Holdings Notice is an Initial Investor
Cash-Out, the Holdings Notice shall state:  (i) the amount received by the
Initial Investors in connection with the Initial Investors Cash-Out (ii) whether
or not the Initial Investors Cash-Out caused the 40% IRR Warrant or the 60% IRR
Warrant to vest and (iii) that, if such vesting occurred, certificates for the
Warrant Shares will be delivered to the Holder at the principal office of
Holdings or such other place as may be designated by Holdings in the Holdings
Notice.

     (f) With respect to an Approved Sale, if the Holdings Notice states that
Holdings anticipates that such event will cause the vesting of the 40% IRR
Warrant or the 60% IRR Warrant, the Holder shall notify Holdings on or before
five days prior to the anticipated closing date of such Approved Sale of such
Holder's exercise and, with respect to an Initial Investors Cash-Out, if the
Holdings Notice states that such event has caused the vesting of either of such
warrants, the Holder shall notify Holdings on or before five days following
receipt of the Holdings Notice of such Holder's exercise of this Warrant (the
"Notice Date") .  This Warrant shall be exercisable by the Holder in whole only,
------------
and not in part, by the surrender of this Warrant and delivery to Holdings on or
before the Notice Date of (i) a duly executed notice of exercise in the form of
Exhibit A (a "Notice of Exercise") and (ii) the Exercise Price for the Warrant
              ------------------
Shares, payable in cash or by wire transfer to a bank account designated by
Holdings.

     (g) This Warrant shall terminate automatically upon the closing of an
Approved Sale and this Warrant shall no longer be of any force or effect, unless
(i) provision is made in writing in connection with such transaction for the
continuance of this Warrant and for the assumption of this Warrant, or for the
substitution for this Warrant of a new Warrant covering the securities of a
successor entity or an affiliate thereof, with appropriate adjustments as to the
number and kind of securities and exercise price, in which event this Warrant
shall continue or be replaced, as the case may be, in the manner and under the
terms so provided; or (ii) the Board of Directors of Holdings shall provide in
writing for such adjustment as it deems appropriate in terms and conditions of
this Warrant, including without limitation (A) accelerating the vesting of this
Warrant and/or (B) providing for the cancellation of this Warrant and its
automatic conversion into the right to receive the securities, cash or other
consideration that the Holder would have been entitled to receive upon
consummation of an Approved Sale had Warrant Shares been issued and outstanding
immediately prior to the Approved Sale (net of the appropriate exercise price).

     (h) This Warrant shall expire on December 20, 2009, unless the Holder's
employment with Holdings or any of its Subsidiaries: (i) is terminated with
Cause or the Holder leaves such employment for any reason, in which case this
Warrant will expire 30 days after the Termination of Employment; or (ii) is
terminated without Cause, or due to death, Disability or Retirement, or the
Holder leaves for any reason and the Board of Directors of Holdings determines
that the Holder left such employment due to personal hardship, in which case
this Warrant will expire 90 days after the Termination of Employment.

     3.  RESERVATION OF SHARES.  Holdings shall at all times reserve for
         ---------------------
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Class B Common Stock as shall be required for issuance and delivery upon
exercise of this Warrant.  If any shares of the Class B Common Stock are or
become listed on any national securities exchange or the Nasdaq National Market,
Holdings shall also list the Warrant Shares, as the case may be, on such
exchange or system, as the case may be, subject to notice of issuance.

     4.  FRACTIONAL SHARES.  Fractional shares or scrip representing fractional
         -----------------
shares may be issued upon the exercise of this Warrant.  Alternatively, Holdings
may, at its option, with respect to any fraction of a share issuable upon any
exercise hereof, pay to the Holder an amount in cash equal to such fraction
multiplied by the greater of (i) the initial Exercise Price per share or (ii)
the current market value of a Warrant Share.  The current market value of a
Warrant Share shall be determined as follows:

     (a) If Warrant Shares are listed on a national securities exchange or
admitted to unlisted trading privileges on such exchange or listed for trading
on the Nasdaq National Market, the current market value shall be the last
reported sale price of a Warrant Share on such exchange or system on the last
day prior to the date of exercise of this Warrant or if no such sale is made on
such day, the average closing bid and asked prices for such day on such exchange
or system;

     (b) If Warrant Shares are not so listed or admitted to unlisted trading
privileges, the current market value shall be the mean of the last reported bid
and asked prices for a Warrant Share reported by the National Quotation Bureau,
Inc. on the last day prior to the date of the exercise of this Warrant; or

     (c) If the Warrant Shares are not so listed or admitted to unlisting
trading privileges and bid and asked prices are not so reported, the current
market value shall be an amount reasonably determined by the Board of Directors
of Holdings.

     5.  NONTRANSFERABILITY.  This Warrant shall not be transferable by the
         ------------------
Holder except that the Holder may transfer this Warrant to (a) his or her
spouse, child, estate, personal representative, heir or successor (b) a trust
for the benefit of the Holder or his or her spouse, child or heir, or (c) a
partnership the partners of which consist solely of the Holder and/or his or her
spouse, child, heir, and/or successor (each, a "Permitted Transferee") and this
                                                --------------------
Warrant is exercisable, during the Holder's lifetime, only by him or her or his
or her spouse or child, or, in the event of the Holder's Disability, his or her
guardian or legal representative.  More particularly (but without limiting the
generality of the foregoing), this Warrant may not be assigned, transferred
(except as aforesaid), pledged or hypothecated in any way (whether by operation
of law or otherwise), and shall not be subject to execution, attachment or
similar process.  Any assignment, transfer, pledge, hypothecation or other
disposition of this Warrant contrary to the provisions hereof, and the levy of
any attachment or similar process upon this Warrant that would otherwise effect
a change in the ownership of this Warrant, shall terminate this Warrant;
provided, however, that in the case of the involuntary levy of any attachment or
similar involuntary process upon this Warrant, the Holder shall have thirty (30)
days after notice thereof to cure such levy or process before this Warrant
terminates.

     6.  RIGHTS OF THE HOLDER.  Holder shall not, by virtue hereof, be entitled
         --------------------
to any rights of a stockholder in Holdings, either at law or equity (including,

respect to the shares of Class B Common Stock purchasable pursuant to this
Warrant are limited to those expressed in this Warrant and are not enforceable
against Holdings except to the extent set forth herein.

         ------------------------
outstanding, the Exercise Price in effect at any time and the number and kind of
securities purchasable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events.  In case
Holdings shall, with respect to its Class B Common Stock (or Common Stock issued
upon conversion thereof):  (i) declare a dividend or make a distribution on its
outstanding shares of common stock in shares of such stock, (ii) subdivide or
reclassify its outstanding shares into a greater number of shares or (iii)
combine or reclassify its outstanding shares into a smaller number of shares,
then the Exercise Price and the number of Warrant Shares purchasable upon
exercise of this Warrant in effect at the time of the record date for such
dividend or distribution, or the effective date of such subdivision, combination
or reclassification, shall be appropriately adjusted as of the effective date of
such dividend, or distribution, subdivision, combination or reclassification, to
reflect such event.  Irrespective of any adjustments in the Exercise Price or
the number or kind of Warrant Shares purchasable upon exercise of this Warrant,
Warrants therefore or thereafter issued may continue to express the same price
and number and kind of shares as are stated in this Warrant initially issued.

     8.  OFFICER'S CERTIFICATE.  Whenever the Exercise Price shall be adjusted
         ---------------------
as required by the provisions of the foregoing, Holdings shall forthwith file in
the custody of its Secretary or an Assistant Secretary at its principal office
and with its stock transfer agent, if any, a certificate of Holdings' Chief
Financial Officer showing the adjusted Exercise Price and number of Warrant
Shares determined as herein provided, setting forth in reasonable detail the
facts requiring such adjustment.  Each such officer's certificate shall be made
available at all reasonable times for inspection by the Holder or any holder of
this Warrant, and Holdings shall, forthwith after each such adjustment, mail, by
certified mail, a copy of such certificate to the Holder or any such holder.

     9.  NOTICES TO WARRANT HOLDERS.  So long as this Warrant shall be
         --------------------------
outstanding, (i) if Holdings shall declare any dividend or make any distribution
upon the Class B Common Stock or (ii) if Holdings shall generally offer to the
holders of the Class B Common Stock for subscription or purchase by them of any
shares of any class of Holdings' capital stock or any other rights to purchase
shares of Holdings' capital stock, then in any such case, Holdings shall cause
notice to be given to the Holder of this Warrant, at least 10 days prior to the
date specified in (x), (y) or (z) below, as the case may be, notice which shall
contain a brief description of the proposed action and stating the date on which
(x) a record is to be taken for the purpose of such dividend, distribution or
offer for subscription or purchase, (y) such reorganization, reclassification,
consolidation, merger, sale, lease, transfer, dissolution, liquidation or
winding up is to take place and the date, if any, that is to be fixed, as of
which the holders of the Class B Common Stock or other capital stock of Holdings
shall receive cash or other property deliverable upon such reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation or
winding up, or (z) the date by which holders of

                                       8
<PAGE>

the Class B Common Stock must elect to participate in the purchase of securities
by Holdings pursuant to the offering referred to in clause (ii) above.

     10.  RECLASSIFICATION OR REORGANIZATION.  Subject to Section 2(g), in case
          ----------------------------------
of any reclassification, conversion or capital reorganization of outstanding
shares of the Class B Common Stock of Holdings, Holdings shall, as a condition
precedent to such reclassification, conversion or capital reorganization, cause
effective provisions to be made so that the Holder shall have the right
thereafter by exercising this Warrant at any time prior to the expiration of
this Warrant, to purchase the kind and amount of shares of stock and other
securities and property receivable upon such reclassification, conversion or
capital reorganization which would have been deliverable to the Holder of this
Warrant on the effective date of the reclassification, conversion or
reorganization had the Holder exercised this Warrant immediately prior to the
event described in this Section 10.  Any such provision shall include provision
for subsequent adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Warrant.  The foregoing
provisions of this Section 10 shall similarly apply to successive
reclassifications, conversions or capital reorganizations of shares of the Class
B Common Stock.

     11.  SECURITIES LAW COMPLIANCE.
          -------------------------

     (a) The Holder of this Warrant, by acceptance hereof, acknowledges that
this Warrant and the Warrant Shares to be issued upon exercise hereof are being
acquired solely for the Holder's own account and not as a nominee for any other
party, and for investment, and that the Holder will not offer, sell, transfer,
assign or otherwise dispose of this Warrant or any Warrant Shares to be issued
upon exercise hereof except under circumstances that will not result in a
