2.   EXERCISE OF WARRANT

          2.1. MANNER OF EXERCISE.

          (a) After September 30, 2001 and until 5:00 P.M., New York City time,
on the Expiration Date, the Holder may from time to time exercise this Warrant,
on any Business Day, for all or any part of the number of shares of Common Stock
purchasable hereunder (subject to adjustment pursuant to Section 4 hereof);
PROVIDED, HOWEVER, if the Borrower has reduced the outstanding Tranche A Term
Loans and Revolving Commitments under the Credit Agreement in an amount no less
than $40,000,000 (PRO RATA between the prepayment of the Tranche A Term Loans
and reductions of the Revolving Commitments) on or prior to September 30, 2001,
(i) this Warrant (or in the event that more than one Warrant represents the
number of shares of Warrant Stock originally making up the Original Warrant No.
CCL-3A, such Warrants) shall be immediately surrendered to the Company by the
Holder for immediate cancellation by the Company and (ii) on and after September
30, 2001, this Warrant (or in the event that more than one Warrant represents
the number of shares of Warrant Stock originally making up the Original Warrant
No. CCL-3A, such Warrants) shall be void, non-transferable, non-negotiable and
of no further force and effect. In order to exercise this Warrant, in whole or
in part, the Holder shall (x) deliver to the Company at the Designated Office a
written notice of the Holder's election to exercise this Warrant (an "Exercise
Notice"), which Exercise Notice shall be irrevocable and specify the number of
shares of Common Stock to be purchased, together with this Warrant and (y) pay
to the Company the Warrant Price (the date on which both such delivery and
payment shall have first taken place being hereinafter sometimes referred to as
the "Exercise Date"). Such Exercise Notice shall be in the form of the
subscription form attached as ANNEX A to this Warrant, duly executed by the
Holder or its duly authorized agent or attorney.

          (b) Upon receipt by the Company of such Exercise Notice, Warrant
and payment of the Warrant Price, the Company shall, as promptly as
practicable, and in any event within five (5) Business Days thereafter,
execute (or cause to be executed) and deliver (or cause to be delivered) to
the Holder a certificate or certificates representing the aggregate number
of full shares of Common Stock issuable upon such exercise, together with
cash in lieu of any fraction of a share, as hereafter provided. The stock
certificate or certificates so delivered shall be, to the extent possible,
in such denomination or denominations as the exercising Holder shall
reasonably request in the Exercise Notice and shall be registered in the
name of the Holder or such other name as shall be designated in the
Exercise Notice. This Warrant shall be deemed to have been exercised and
such certificate or certificates shall be deemed to have been issued, and
the Holder or any other Person so designated to be named therein shall be
deemed to have become a holder of record of such shares of Common Stock for
all purposes, as of the Exercise Date, PROVIDED, HOWEVER, that a Holder
shall not be entitled to revoke, rescind or modify its Exercise Notice
after such notice is delivered to the Company.

          (c) Payment of the Warrant Price shall be made (i) by delivery to the
Company of a certified or official bank check in the amount of such Warrant
Price or (ii) without the payment of cash, by (1) canceling (or entering into
any other arrangement having substantially the same economic effect with respect
to the) outstanding Loans (including accrued interest thereon through the
Exercise Date) held and designated by such Holder in an amount equal to the
Warrant Price, subject to the satisfaction of any requirements in respect of the
cancellation of, or other arrangement with respect to, the Loans under the
Credit Agreement; PROVIDED THAT the Company shall not be required to (I) seek or
effect any amendment or modification of, or interpretation with respect to, the
Credit Agreement to effect the provisions of this subsection (ii)(1) and (II)
pay, setoff or cancel (or caused to be paid, setoff or canceled) any sum (except
with respect to outstanding Loans as permitted under the Credit Agreement) or
expend any resources in order to effect the provisions of this subsection
(ii)(1), (2) reducing the number of shares of Common Stock which would be
obtainable upon the exercise of this Warrant by the payment of the Warrant Price
solely in cash so as to yield a number of shares of Common Stock upon the
exercise of this Warrant equal to the product of (x) the number of shares of
Common Stock issuable as of the Exercise Date upon the exercise of this Warrant
(if payment of the Warrant Price were being made in cash) and (y) the Cashless
Exercise Ratio or (3) any combination of permitted exercises pursuant to clauses
(1) and (2) above. An exercise of this Warrant in accordance with the
immediately preceding clause (ii) is herein called a "Cashless Exercise".
Subject to Section 2.1 hereof, the rights represented by this Warrant shall be
exercisable at the election of the Holder thereof either in full at any time or
from time to time in part and in the event that a certificate is surrendered for
exercise of less than all the Warrants represented by such certificate at any
time prior to the Expiration Date, a new certificate representing the remaining
Warrants shall be issued.

          (d) If this Warrant shall have been exercised in part, the Company
shall, at the time of delivery of the certificate or certificates representing
the shares of Common Stock being issued, deliver to the Holder a new Warrant
evidencing the rights of the Holder to purchase the unpurchased shares of
Warrant Stock called for by this Warrant. Such new Warrant shall in all other
respects be identical with this Warrant.

          2.2. NO LIENS. All shares of Common Stock issuable upon the exercise
of this Warrant pursuant to the terms hereof shall be validly issued, fully paid
and nonassessable, issued without violation of any preemptive rights and free
and clear of all Liens (other than any created by actions of the Holder).

          2.3. FRACTIONAL SHARES. The Company shall not be required to issue a
fractional share of Common Stock upon exercise of any Warrant. As to any
fraction of a share that the Holder of one or more Warrants, the rights under
which are exercised in the same transaction, would otherwise be entitled to
purchase upon such exercise, the Company shall pay a cash adjustment in respect
of such final fraction in an amount equal to the same fraction of the Fair Value
of one share of Common Stock on the Exercise Date.

          2.4. CONTINUED VALIDITY AND APPLICATION. A holder of shares of
Warrant Stock issued upon the exercise of this Warrant, in whole or in
part, including any permitted transferee of such shares (other than a
permitted transferee in whose hands such shares no longer constitute
Warrant Stock as defined herein), shall continue, with respect to such
shares, to be entitled to all rights and to be subject to all obligations
that are applicable to such holder by the terms of this Warrant. The
Company shall, at the time of any exercise of this Warrant or any transfer
of Warrant Stock, upon the written request of the holder of the shares of
Warrant Stock issued in connection with such exercise or transfer,
acknowledge in writing, in a form reasonably satisfactory to such holder,
its continuing obligation to afford to such holder such rights referred to
in this Section 2.4; PROVIDED, HOWEVER, that if such holder of Warrant
Stock shall fail to make any such written request, such failure shall not
affect the continuing obligation of the Company to afford to such holder
all such rights.

3.   TRANSFER, DIVISION AND COMBINATION

          3.1. TRANSFER. Subject to compliance with Section 8 hereof, each
transfer of this Warrant and all rights hereunder, in whole or in part, shall be
registered on the books of the Company to be maintained for such purpose, upon
surrender of this Warrant at the Designated Office, together with a written
assignment of this Warrant in the form attached as ANNEX B to this Warrant, duly
executed by the Holder or its duly authorized agent or attorney. Upon such
surrender and delivery, the Company shall, subject to Section 8 hereof, execute
and deliver a new Warrant or Warrants in the name of the assignee or assignees
and in the denominations specified in such instrument of assignment, and shall
issue to the assignor a new Warrant evidencing the portion of this Warrant not
so assigned and this Warrant shall promptly be cancelled. A Warrant, if properly
assigned in compliance with Section 8 hereof, may be exercised by the new Holder
for the purchase of shares of Common Stock without having a new Warrant issued.
This Warrant may not be transferred by a Holder prior to October 1, 2001.

          3.2. DIVISION AND COMBINATION. Subject to compliance with the
applicable provisions of this Warrant, this Warrant may be divided or combined
with other Warrants upon presentation hereof at the Designated Office, together
with a written notice specifying the names and denominations in which new
Warrants are to be issued, signed by the Holder or its duly authorized agent or
attorney. Subject to compliance with the applicable provisions of this Warrant
as to any transfer which may be involved in such division or combination, the
Company shall execute and deliver a new Warrant or Warrants in exchange for the
Warrant or Warrants to be divided or combined in accordance with such notice.

          3.3. EXPENSES. The Company shall prepare, issue and deliver at its own
expense any new Warrant or Warrants required to be issued under this Section 3.

          3.4. MAINTENANCE OF BOOKS. The Company agrees to maintain, at the
Designated Office, books for the registration and transfer of the Warrants.

4.   ANTIDILUTION PROVISIONS

          The number of shares of Common Stock for which this Warrant is
exercisable and the Exercise Price shall be subject to adjustment from time to
time as set forth in this Section 4.

          4.1. STOCK DIVIDENDS, SUBDIVISIONS AND COMBINATIONS. If at any time
the Company shall:

          (a) take a record of the holders of its Common Stock for the purpose
     of entitling them to receive a dividend payable in, or other distribution
     of, additional shares of Common Stock,

          (b) subdivide, split or reclassify its outstanding shares of Common
     Stock into a larger number of shares of such Common Stock, or

          (c) combine its outstanding shares of Common Stock into a smaller
     number of shares of such Common Stock,

then the Exercise Price shall be adjusted to equal the product of the Exercise
Price in effect immediately prior to such event multiplied by a fraction the
numerator of which is equal to the number of shares of Common Stock Outstanding
immediately prior to the adjustment and the denominator of which is equal to the
number of shares of Common Stock Outstanding immediately after such adjustment.

          4.2. ISSUANCE OF ADDITIONAL SHARES OF COMMON STOCK. (a) If at any time
the Company shall issue or sell any shares of Common Stock in a Subsequent
Issuance for a consideration per share that is less than the Fair Value thereof,
then, forthwith upon such issuance or sale, the Exercise Price shall be reduced
to the price calculated by dividing (i) an amount equal to the sum of (x) the
number of shares of Common Stock Fully Diluted Outstanding immediately prior to
such Subsequent Issuance multiplied by the then existing Fair Value per share,
plus (y) the aggregate consideration (determined in accordance with the
provisions of Section 4.7 hereof), if any, received by the Company in connection
with such Subsequent Issuance, by (ii) the total number of shares of Common
Stock Fully Diluted Outstanding immediately after such Subsequent Issuance.

          (b) The provisions of this Section 4.2 shall not apply to (i) any
issuance of Common Stock for which an adjustment is provided for under Section
4.1 hereof or (ii) any issuance or sale of Common Stock pursuant to the exercise
of any Stock Purchase Rights or Convertible Securities to the extent that an
adjustment shall have been previously made hereunder in connection with the
issuance of such Stock Purchase Rights or Convertible Securities pursuant to the
provisions of Section 4.3 hereof.

          4.3. ISSUANCES OF STOCK PURCHASE RIGHTS AND CONVERTIBLE SECURITIES

          (a) In the event that the Company shall at any time issue, sell or
grant any Stock Purchase Rights to any Person in a Subsequent Issuance, then,
for the purpose of Section 4.2 hereof, the Company shall be deemed to have
issued at that time a number of shares of Common Stock equal to the maximum
number of shares of Common Stock that are or may become issuable upon exercise
of such Stock Purchase Rights (or upon exercise of any Convertible Securities
issuable upon exercise of such Stock Purchase Rights) for a consideration per
share equal to (i) the aggregate consideration per share (determined in
accordance with the provisions of Section 4.7 hereof) received by the Company in
connection with the issuance, sale or grant of such Stock Purchase Rights plus
(ii) the minimum amount of such consideration per share receivable by the
Company in connection with the exercise of such Stock Purchase Rights (and the
exercise of any Convertible Securities issuable upon exercise of such Stock
Purchase Rights).

          (b) In the event that the Company shall at any time issue or sell
any Convertible Securities to any Person in a Subsequent Issuance, then,
for the purposes of Section 4.2 hereof, the Company shall be deemed to have
issued at that time a number of shares of Common Stock equal to the maximum
number of shares of Common Stock that are or may become issuable upon the
exercise of the conversion or exchange rights associated with such
Convertible Securities for a consideration per share equal to (i) the
aggregate consideration per share (determined in accordance with the
provisions of Section 4.7 hereof) received by the Company in connection
with the issuance or sale of such Convertible Securities plus (ii) the
minimum amount of such consideration per share receivable by the Company in
connection with the exercise of such conversion or exchange rights.

          (c) If, at any time after any adjustment of the Exercise Price shall
have been made hereunder as the result of any issuance, sale or grant of any
Stock Purchase Rights or Convertible Securities, the maximum number of shares
issuable upon exercise of such Stock Purchase Rights or of the rights of
conversion or exchange associated with such Convertible Securities shall
increase, or the minimum amount of consideration per share receivable in
connection with such exercise shall decrease, whether by operation of any
antidilution rights pertaining to such Stock Purchase Rights or Convertible
Securities, by agreement of the parties or otherwise, the Exercise Price then in
effect shall first be readjusted to eliminate the effects of the original
issuance, sale or grant of such Stock Purchase Rights or Convertible Securities
on such Exercise Price and then readjusted as if such Stock Purchase Rights or
Convertible Securities had been issued on the effective date of such increase in
number of shares or decrease in consideration.

          (d) If, at any time after any adjustment of the Exercise Price shall
have been made hereunder as the result of any issuance, sale or grant of any
Stock Purchase Rights or Convertible Securities, any of such Stock Purchase
Rights or the rights of conversion or exchange associated with such Convertible
Securities shall expire by their terms or any of such Stock Purchase Rights or
Convertible Securities shall be repurchased by the Company or a Subsidiary
thereof for a consideration per underlying share of Common Stock not exceeding
the amount of such consideration received by the Company in connection with the
issuance, sale or grant of such Stock Purchase Rights or Convertible Securities,
the Exercise Price then in effect shall forthwith be increased to the Exercise
Price that would have been in effect if such expiring Stock Purchase Rights or
rights of conversion or exchange or such repurchased Stock Purchase Rights or
Convertible Securities had never been issued. Similarly, if at any time after
any such adjustment of the Exercise Price shall have been made pursuant to
Section 4.2 hereof, (i) any additional consideration is received or becomes
receivable by the Company in connection with the issuance or exercise of such
Stock Purchase Rights or Convertible Securities or (ii) there is a reduction in
the conversion ratio applicable to such Convertible Securities so that fewer
shares of Common Stock will be issuable upon the conversion or exchange thereof
or there is a decrease in the number of shares of Common Stock issuable upon
exercise of such Stock Purchase Rights, the Exercise Price then in effect shall
be forthwith readjusted to the Exercise Price that would have been in effect had
such changes taken place at the time that such Stock Purchase Rights or
Convertible Securities were initially issued, granted or sold. In no event shall
any readjustment under this Section 4.3(d) affect the validity of any shares of
Warrant Stock issued upon any exercise of this Warrant prior to such
readjustment, nor shall any such readjustment have the effect of increasing the
Exercise Price above the Exercise Price that would have been in effect if the
related Stock Purchase Rights or Convertible Securities had never been issued.

          4.4. OTHER ADJUSTMENTS. Notwithstanding any other provision of
this Warrant, in the event the Company consummates any transaction or
series of transactions which results in an antidilution or similar
adjustment pursuant to the terms of any Convertible Securities or Stock
Purchase Rights, in each case primarily for the benefit of any member of
management or any director of the Company, and such antidilution or similar
adjustment is implemented pursuant to and in compliance with the terms of
such instrument, the Company shall make a proportionate adjustment to this
Warrant; PROVIDED THAT the foregoing and Section 4.8 hereof shall not be
interpreted to result in, or have the effect of requiring, an adjustment to
this Warrant upon a repricing of options or similar equity instruments of
the Company Beneficially Owned by any employee or director of the Company
or any Subsidiary of the Company which is approved in good faith by the
Board of Directors (or a committee thereof) of the Company.

          4.5. ADJUSTMENT OF NUMBER OF SHARES PURCHASABLE. Upon any adjustment
of the Exercise Price as provided in Sections 4.1, 4.2, 4.3, 4.4, 4.6 and 4.8
hereof, as applicable, the Holder hereof shall thereafter be entitled to
purchase upon the exercise of this Warrant, at the Exercise Price resulting from
such adjustment, the number of shares of Common Stock (calculated to the nearest
1/100th of a share) obtained by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of shares of Common Stock
issuable on the exercise hereof immediately prior to such adjustment and
dividing the product thereof by the Exercise Price resulting from such
adjustment.

          4.6. REORGANIZATION, RECLASSIFICATION, MERGER, CONSOLIDATION OR
DISPOSITION OF ASSETS. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where
there is any change whatsoever in, or distribution with respect to, the
Outstanding Common Stock), or sell, transfer or otherwise dispose of all or
substantially all of its property, assets or business to another
corporation and, pursuant to the terms of such reorganization,
reclassification, merger, consolidation or disposition of assets, (a)
shares of common stock of the successor or acquiring corporation or of the
Company (if it is the surviving corporation) or (b) any cash, shares of
stock or other securities or property of any nature whatsoever (including
warrants or other subscription or purchase rights) in addition to or in
lieu of common stock of the successor or acquiring corporation ("Other
Property") are to be received by or distributed to the holders of Common
Stock who are holders immediately prior to such transaction, then the
Holder of this Warrant shall have the right thereafter to receive, upon
exercise of this Warrant, the number of shares of common stock of the
successor or acquiring corporation or of the Company, if it is the
surviving corporation, and Other Property receivable upon or as a result of
such reorganization, reclassification, merger, consolidation or disposition
of assets by a holder of the number of shares of Common Stock for which
this Warrant is exercisable immediately prior to such event. In such event,
the aggregate Exercise Price otherwise payable for the shares of Common
Stock issuable upon exercise of this Warrant shall be allocated among the
shares of common stock and Other Property receivable as a result of such
reorganization, reclassification, merger, consolidation or disposition of
assets in proportion to the respective fair market values of such shares of
common stock and Other Property as determined in good faith by the Board of
Directors of the Company. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the
successor or acquiring corporation (if other than the Company) shall
expressly assume the due and punctual observance and performance of each
and every covenant and condition of this Warrant to be performed and
observed by the Company and all the obligations and liabilities hereunder,
subject to such modifications as may be reasonably deemed appropriate (as
determined by resolution of the Board of Directors of the Company) in order
to provide for adjustments of any shares of the common stock of such
successor or acquiring corporation for which this Warrant thus becomes
exercisable, which modifications shall be as equivalent as practicable to
the adjustments provided for in this Section 4. For purposes of this
Section 4.6, "common stock of the successor or acquiring corporation" shall
include stock of such corporation of any class that is not preferred as to
dividends or assets over any other class of stock of such corporation and
that is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities that are convertible into
or exchangeable for any such stock, either immediately or upon the arrival
of a specified date or the happening of a specified event and any warrants
or other rights to subscribe for or purchase any such stock. The foregoing
provisions of this Section 4.6 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or dispositions
of assets.

          4.7. DETERMINATION OF CONSIDERATION. For purposes of Sections 4.2,
4.3, 4.4, 4.6 and 4.8 hereof, as applicable, the consideration received and/or
receivable by the Company in connection with the issuance, sale, grant or
exercise of additional shares of Common Stock, Stock Purchase Rights or
Convertible Securities, irrespective of the accounting treatment of such
consideration, shall be valued as follows:

          (a) CASH PAYMENT. In the case of cash, the net amount received by the
     Company after deduction of any underwriting commissions or concessions paid
     or allowed by the Company.

          (b) SECURITIES OR OTHER PROPERTY. In the case of securities or other
     property, the fair market value thereof as of the date immediately
     preceding such issuance, sale, grant or exercise as determined in good
     faith by the Board of Directors of the Company.

          (c) ALLOCATION RELATED TO COMMON STOCK. In the event shares of Common
     Stock are issued or sold together with other securities or other assets of
     the Company for a consideration which covers both, the consideration
     received (computed as provided in (a) and (b) above) shall be allocable to
     such shares of Common Stock as determined in good faith by the Board of
     Directors of the Company.

          (d) ALLOCATION RELATED TO STOCK PURCHASE RIGHTS AND CONVERTIBLE
     SECURITIES. In case any Stock Purchase Rights or Convertible Securities
     shall be issued or sold together with other securities or other assets of
     the Company, together comprising one integral transaction in which no
     specific consideration is allocated to the Stock Purchase Rights or
     Convertible Securities, the consideration allocable to such Stock Purchase
     Rights or Convertible Securities shall be determined in good faith by the
     Board of Directors of the Company.

          (e) DIVIDENDS IN SECURITIES. In case the Company shall declare a
     dividend or make any other distribution upon any stock of the Company
     payable in either case in Common Stock or Convertible Securities, such
     Common Stock or Convertible Securities, as the case may be, issuable in
     payment of such dividend or distribution shall be deemed to have been
     issued or sold without consideration.

          (f) MERGER, CONSOLIDATION OR SALE OF ASSETS. In case any shares
     of Common Stock, Stock Purchase Rights or Convertible Securities shall
     be issued in connection with any merger or consolidation in which the
     Company is the surviving corporation, the amount of consideration
     therefor shall be deemed to be the fair value of such portion of the
     assets and business of the non-surviving corporation attributable to
     such Common Stock, Stock Purchase Rights or Convertible Securities, as
     is determined in good faith by the Company's Board of Directors.

          4.8. OTHER DILUTIVE EVENTS. In case any event shall occur as to which
the other provisions of this Section 4 are not strictly applicable but as to
which the failure to make any adjustment would not fairly protect the purchase
rights represented by this Warrant in accordance with the essential intent and
principles hereof as determined in good faith by the Company's Board of
Directors (including, without limitation, the issuance of equity securities
(other than as specifically provided in Sections 4.1, 4.2, 4.3, 4.4 and 4.6),
the distribution to all holders of Common Stock of evidences of indebtedness,
cash or other property (other than cash dividends paid in the ordinary course of
business), the granting of "phantom stock" rights or "stock appreciation rights"
or the repurchase of outstanding shares of Common Stock, Convertible Securities
or Stock Purchase Rights for a purchase price exceeding Fair Value; PROVIDED,
HOWEVER, that the Company shall be permitted to effect (i) a self tender offer
of Common Stock up to 10% of the Fully Diluted Outstanding Common Stock at a
price not to exceed Fair Value on the date the self tender offer is first
publicly announced by the Company and (ii) a redemption of Convertible
Securities in accordance with the terms of such instrument as in effect on the
date hereof), then, in each such case, the Majority Warrant Holders may select
an independent investment banking firm of nationally recognized standing and
reasonably acceptable to the Company to make a determination as to the
adjustment, if any, required to be made on a basis consistent with the essential
intent and principles established herein as a result of such event in order to
preserve the purchase rights represented by the Warrants. If the investment bank
selected by the Majority Warrant Holders is not reasonably acceptable to the
Company, and the Company and the Majority Warrant Holders cannot agree on a
mutually acceptable investment bank, then the Company and the Majority Warrant
Holders shall each choose one such investment bank and the respective chosen
firms shall jointly select a third investment bank, which shall make the
determination. The Company, on the one hand, and all affected holders of
Warrants or Warrant Stock, on the other hand, shall each pay 50% of the costs
and fees of each such investment bank (the holders of Warrants and Warrant Stock
shall agree among themselves the pro rata allocation of such costs and
expenses), and the decision of the investment bank making such determination
shall be final and binding on the Company and all affected holders of Warrants
or Warrant Stock. Promptly after receipt by the Company of the opinion of such
investment bank as to any such required adjustments, the Company shall take any
actions necessary to implement same.

          4.9. OTHER PROVISIONS APPLICABLE TO ADJUSTMENTS UNDER THIS SECTION 4.
The following provisions shall be applicable to the adjustments provided for
pursuant to this Section 4:

          (a) WHEN ADJUSTMENTS TO BE MADE. The adjustments required by this
     Section 4 shall be made whenever and as often as any specified event
     requiring such an adjustment shall occur. For the purpose of any such
     adjustment, any specified event shall be deemed to have occurred at the
     close of business on the date of its occurrence.

          (b) RECORD DATE. In case the Company shall take a record of the
     holders of the Common Stock for the purpose of entitling them (i) to
     receive a dividend or other distribution payable in Common Stock,
     Convertible Securities or Stock Purchase Rights or (ii) to subscribe
     for or purchase Common Stock, Convertible Securities or Stock Purchase
     Rights, then all references in this Section 4 to the date of the
     issuance or sale of such shares of Common Stock, Convertible
     Securities or Stock Purchase Rights shall be deemed to be references
     to such record date.

          (c) FRACTIONAL INTERESTS. In computing adjustments under this Section
     4, fractional interests in Common Stock shall be taken into account to the
     nearest 1/100th of a share.

          (d) WHEN ADJUSTMENT NOT REQUIRED. If the Company shall take a record
     of the holders of its Common Stock for the purpose of entitling them to
     receive a dividend or distribution to which the provisions of Section 4.1
     hereof would apply, but 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 shall be required
     by reason of the taking of such record and any such adjustment previously
     made in respect thereof shall be rescinded and annulled.

          (e) MAXIMUM EXERCISE PRICE. Except as provided in Section 4.1 hereof,
     at no time shall the Exercise Price per share of Common Stock exceed the
     amount set forth in the first paragraph of the preamble of this Warrant.

          (f) CERTAIN LIMITATIONS. Notwithstanding anything herein to the
     contrary, the Company agrees not to enter into any transaction that, by
     reason of any adjustment under Sections 4.1, 4.2, 4.3, 4.4, 4.6 and 4.8
     hereof, as applicable, would cause the Exercise Price to be less than the
     par value of the Common Stock, if any, unless the Company first reduces the
     par value of the Common Stock to be less than the Exercise Price that would
     result from such transaction.

          (g) TAX ADJUSTMENTS. The Company may make such reductions in the
     Exercise Price or increase in the number of Common Stock to be received by
     any Holder upon the exercise or exchange of this Warrant, in addition to
     those adjustments required by this Section 4, as it in its sole discretion
     shall determine to be advisable in order that any consolidation or
     subdivision of the Common Stock, or any issuance wholly for cash of any
     shares of Common Stock, or any issuance wholly for cash of shares of Common
     Stock or Convertible Securities, or any stock dividend, or any issuance of
     Stock Purchase Rights hereinafter made by the Company to the holders of its
     Common Stock shall not be taxable to such holders.

          (h) CERTAIN BUSINESS COMBINATIONS. The Company will not merge or
     consolidate with or into, or sell, transfer or lease all or substantially
     all of its property to, any other entity unless the successor or purchasing
     entity, as the case may be (if not the Company), shall expressly agree to
     provide to each Holder the securities, cash or property required by Section
     4.6 hereof upon the exercise or exchange of this Warrant and expressly
     assumes, by supplemental agreement, the due and punctual performance and
     observance of each and every covenant and condition of this Warrant to be
     performed and observed by the Company; PROVIDED, HOWEVER, that the initial
     obligation of such successor with respect to the exercise or exchange of
     this Warrant shall be only as set forth in Section 4.6 hereof.

          (i) NOTICE OF ADJUSTMENTS. Whenever the number of shares of Common
     Stock for which this Warrant is exercisable or the Exercise Price shall be
     adjusted pursuant to this Section 4, the Company shall forthwith prepare a
     certificate to be executed by the chief financial officer of the Company
     setting forth, in reasonable detail, the event requiring the adjustment and
     the method by which such adjustment was calculated, specifying the number
     of shares of Common Stock for which this Warrant is exercisable and (if
     such adjustment was made pursuant to Section 4.6 hereof) describing the
     number and kind of any other shares of stock or Other Property for which
     this Warrant is exercisable, and any related change in the Exercise Price,
     after giving effect to such adjustment or change. The Company shall
     promptly cause a signed copy of such certificate to be delivered to each
     Holder in accordance with Section 14.3 hereof. The Company shall keep at
     its principal office or at the Designated Office, if different, copies of
     all such certificates and cause the same to be available for inspection at
     said office during normal business hours by any Holder or any prospective
     transferee of a Warrant designated by a Holder thereof.

          (j) INDEPENDENT APPLICATION. Except as otherwise provided herein, all
     subsections of this Section 4 are intended to operate independently of one
     another (but without duplication). If any single transaction would require
     adjustment of the Exercise Price pursuant to more than one subsection of
     this Section 4, only one adjustment shall be made and such adjustment shall
     be the amount of adjustment which has the highest absolute value.

5.   NO IMPAIRMENT

          The Company shall not by any action, including, without limitation,
amending its charter documents or through any reorganization, reclassification,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other similar voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of the Holder against impairment. Without limiting the generality of the
foregoing, the Company shall 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, free
and clear of all Liens, and shall use its best efforts to obtain all such
authorizations, exemptions or consents from any public regulatory body having
jurisdiction over it as may be necessary to enable the Company to perform its
obligations under this Warrant.

6.   RESERVATION AND AUTHORIZATION OF COMMON STOCK; REGISTRATION WITH OR
     APPROVAL OF ANY GOVERNMENTAL AUTHORITY

          From and after the Original Issue Date, the Company shall at all
times reserve and keep available for issuance upon the exercise of the
Warrants such number of its authorized but unissued shares of Common Stock
as will be sufficient to permit the exercise in full of all outstanding
Warrants. All shares of Common Stock issuable pursuant to the terms hereof,
when issued upon exercise of this Warrant with payment therefor in
accordance with the terms hereof, shall be duly and validly issued and
fully paid and nonassessable, not subject to preemptive rights and shall be
free and clear of all Liens. Before taking any action that would result in
an adjustment in the number of shares of Common Stock for which this
Warrant is exercisable or in the Exercise Price, the Company shall obtain
all such authorizations or exemptions thereof, or consents thereto, as may
be necessary from any public regulatory body or bodies having jurisdiction
over such action. If any shares of Common Stock required to be reserved for
issuance upon exercise of Warrants require registration or qualification
with any governmental authority under any federal or state law (other than
under the Securities Act or any state securities law) before such shares
may be so issued, the Company will in good faith and as expeditiously as
possible and at its expense endeavor to cause such shares to be duly
registered or qualified, as the case may be.

7.   NOTICE OF CORPORATE ACTIONS; TAKING OF RECORD; TRANSFER BOOKS

          7.1. NOTICES OF CORPORATE ACTIONS. In the event of: (a) any taking by
the Company of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend or distribution, or any right to subscribe for, purchase or otherwise
acquire any shares of capital stock of any class or any other securities, (b)
any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any consolidation or
merger involving the Company and any other Person or any transfer or other
disposition of all or substantially all the assets of the Company to another
Person, (c) any voluntary or involuntary dissolution, liquidation or winding-up
of the Company, (d) any amendment of the Certificate of Incorporation of the
Company, (e) any registration or public offering of Common Stock or (f) any
action taken by the Company which could in any way dilute the Common Stock for
which this Warrant is exercisable, the Company shall mail to each Holder of a
Warrant in accordance with the provisions of Section 14.3 hereof a notice
specifying (i) the date or expected date on which any such record is to be taken
for the purpose of such dividend, distribution or right, and the amount and
character of such dividend, distribution or right and (ii) the date or expected
date on which any such reorganization, reclassification, recapitalization,
consolidation, merger, transfer, disposition, dissolution, liquidation,
winding-up or other event is to take place, the time, if any such time is to be
fixed, as of which the holders of record of Common Stock shall be entitled to
exchange their shares of Common Stock for the securities or Other Property
deliverable upon such reorganization, reclassification, recapitalization,
consolidation, merger, transfer, disposition, dissolution, liquidation,
winding-up or other event and a description in reasonable detail of the
transaction. Such notice shall be mailed to the extent practicable under the
circumstances as determined in the reasonable judgment of an officer of the
Company at least fifteen (15) days prior to the date therein specified, and
shall describe the material terms of the matter in question. In the event that
the Company at any time sends any other notice to the holders of its Common
Stock, it shall concurrently send a copy of such notice to each Holder of a
Warrant.

          7.2. TAKING OF RECORD. In the case of all dividends or other
distributions by the Company to the holders of its Common Stock with respect to
which any provision of any Section hereof refers to the taking of a record of
such holders, the Company will in each such case take such a record and will
take such record as of the close of business on a Business Day.

          7.3. CLOSING OF TRANSFER BOOKS. The Company shall not at any time,
except upon dissolution, liquidation or winding up of the Company, close its
stock transfer books or Warrant transfer books so as to result in preventing or
delaying the exercise or transfer of any Warrant.

          7.4. NO RIGHTS AS STOCKHOLDERS. Except as provided herein,
Holders shall have no rights as holders of Common Stock solely as a result
of being the Beneficial Owner of a Warrant. Holders shall have no right to
vote, consent or otherwise participate with respect to matters submitted to
a vote of the stockholders of the Company.

8.   TRANSFER

          The Holder, by acceptance of this Warrant, agrees to be bound by the
provisions of this Section 8.

          8.1. RESTRICTIONS ON TRANSFER. Neither this Warrant nor any shares of
Restricted Common Stock issued upon the exercise hereof shall be Transferred
other than pursuant to an effective registration statement under the Securities
Act or an exemption from the registration provisions thereof. This Warrant may
not be offered, sold or otherwise transferred by a Holder prior to October 1,
2001. Subject to Section 2.1(a) hereof, the Holder of this Warrant by its
acceptance hereof agrees to offer, sell or otherwise transfer such Warrant,
after September 30, 2001 and prior to the date (the "Resale Restriction
Termination Date") which is two years after the later of the Original Issue Date
and the last date on which the Company or any Affiliate of the Company was the
owner of this Warrant (or any predecessor of this Warrant), only (a) to the
Company, (b) pursuant to a registration statement that has been declared
effective under the Securities Act, (c) for so long as this Warrant is eligible
for resale pursuant to Rule 144A under the Securities Act ("Rule 144A"), to a
person it reasonably believes is a "qualified institutional buyer" as defined in
Rule 144A that purchases for its own account or for the account of a qualified
institutional buyer to whom notice is given that the transfer is being made in
reliance on Rule 144A, (d) to an "accredited investor" within the meaning of
Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is an
institutional accredited investor acquiring the security for its own account or
for the account of such an institutional accredited investor for investment
purposes and not with a view to or for offer or sale in connection with any
distribution in violation of the Securities Act or (e) pursuant to any other
available exemption from the registration requirements of the Securities Act,
including the exemption provided for by Rule 144 (if available), subject to the
Company's right prior to any such offer, sale or transfer pursuant to clauses
(d) or (e) to require the delivery of an Opinion of Counsel, certification
and/or other information satisfactory to it. The legends contained in Section
8.2 hereof will be removed upon the written request of the Holder after the
Resale Restriction Termination Date. In connection with any Transfer, the Holder
will deliver to the Company such certificates and other information as the
Company may require to confirm that the transfer complies with the foregoing
restrictions. Holders of the Warrants or the Restricted Common Stock, as the
case may be, shall not be entitled to Transfer such Warrants or such Restricted
Common Stock except in accordance with this Section 8.1.

          8.2. RESTRICTIVE LEGENDS.

          (a) Except as otherwise provided in this Section 8, each certificate
for Warrant Stock initially issued upon the exercise of this Warrant, and each
certificate for Warrant Stock issued to any subsequent transferee of any such
certificate, shall be stamped or otherwise imprinted with two legends in
substantially the following forms:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE
     SECURITIES LAW. THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF
     AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO
     THE DATE (THE "RESALE RESTRICTION TERMINATION DATE") WHICH IS TWO
     YEARS AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF AND THE LAST

     TO THE COMPANY, (B) PURSUANT TO A REGISTRATION STATEMENT THAT HAS BEEN
     DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE

     "THIS WARRANT MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED
     PRIOR TO OCTOBER 1, 2001."

     "THIS WARRANT IS SUBJECT TO CANCELLATION PRIOR TO EXERCISE AS SET
     FORTH HEREIN."

          8.3. TERMINATION OF SECURITIES LAW RESTRICTIONS. Notwithstanding
the foregoing provisions of Section 8 and subject to Section 2.1(a) hereof,
the restrictions imposed by Section 8.1 hereof upon the transferability of
the Warrants and the Restricted Common Stock and the legend requirements of
Section 8.2 hereof shall terminate as to any particular Warrant or shares
of Restricted Common Stock when the Company shall have received from the
holder thereof an Opinion of Counsel to the effect that such legend is not
required in order to ensure compliance with the Securities Act. Whenever
the restrictions imposed by Sections 8.1 and 8.2 shall terminate as to this
Warrant, as hereinabove provided, the Holder hereof shall be entitled to
receive from the Company, at the expense of the Company, a new Warrant
bearing the following legend in place of the restrictive legend set forth
hereon:

     "THE RESTRICTIONS ON TRANSFERABILITY OF THE WITHIN WARRANT
     CONTAINED IN SECTIONS 8.1 AND 8.2 HEREOF TERMINATED ON
     ______________, 20__, AND ARE OF NO FURTHER FORCE AND EFFECT."

All Warrants issued upon registration of transfer, division or combination of,
or in substitution for, any Warrant or Warrants entitled to bear such legend
shall have a similar legend endorsed thereon. Wherever the restrictions imposed
by this Section 8.3 shall terminate as to any share of Restricted Common Stock,
as hereinabove provided, the holder thereof shall be entitled to receive from
the Company, at the Company's expense, a new certificate representing such
Common Stock not bearing the restrictive legend set forth in Section 8.2(a)
hereof.

          8.4. LISTING ON SECURITIES EXCHANGE. If the Company shall maintain a
listing of any shares of Common Stock on any securities exchange or on NASDAQ,
it shall at its expense, to the extent permitted by the rules and regulations of
such securities exchange or NASDAQ, list thereon, maintain and, when necessary,
increase such listing of, all shares of Warrant Stock issued or, to the extent
permissible under the applicable securities exchange rules or NASDAQ, issuable
upon the exercise of this Warrant.

          8.5. NOMINEES FOR BENEFICIAL OWNERS. In the event that any Warrant
Stock is held by a nominee for the Beneficial Owner thereof, the Beneficial
Owner thereof may, at its election, be treated as the holder of such Warrant
Stock for purposes of any request or other action by any holder or holders of
Warrant Stock pursuant to this Warrant or any determination of any number or
percentage of shares of Warrant Stock held by any holder or holders of Warrant
Stock contemplated by this Agreement. If the Beneficial Owner of any Warrant
Stock so elects, the Company may require assurances reasonably satisfactory to
it of such owner's Beneficial Ownership of such Warrant Stock; PROVIDED,
HOWEVER, that in no event shall there be "double-counting" of Warrants or
Warrant Stock.

          8.6 PAYMENT OF TAXES. The Company shall not be required to issue or
deliver Warrant Stock or a new Warrant unless or until the Person or Persons
requesting the issuance thereof shall have paid to the Company the amount of any
applicable transfer or stamp taxes or shall have established to the reasonable
satisfaction of the Company that such taxes have been paid or are not due and
owing.

9.   SUPPLYING INFORMATION; RULE 144

          The Company shall cooperate with each holder of a Warrant and
each holder of Warrant Stock in supplying such information as may be
reasonably necessary for such holder to complete and file any information
reporting forms presently or hereafter required by the Commission as a
condition to the availability of an exemption from the Securities Act for
the sale of any Warrant or shares of Warrant Stock. The Company shall use
its best efforts to at all times make public information available (as such
phrase is interpreted under Rule 144 of the Securities Act) so as to afford
the holders of the Warrants and the Warrant Stock the benefits of Rule 144
of the Securities Act in connection with resales, and upon the reasonable
written request of any Holder shall provide such Holder with such financial
statements, reports and other information as may be reasonably required to
permit such Holder to sell Warrants or shares of Warrant Stock to one or
more "Qualified Institutional Buyers" under Rule 144A of the Securities
Act, in each case as such Rule may be amended from time to time or replaced
or supplemented by any similar rule or regulation hereafter adopted by the
Commission.

10.  LOSS OR MUTILATION

          Upon receipt by the Company from any Holder of evidence reasonably
satisfactory to it of the ownership of and the loss, theft, destruction or
mutilation of this Warrant and an indemnity reasonably satisfactory to it and,
in case of mutilation, upon surrender and cancellation hereof, the Company will
execute and deliver in lieu hereof a new Warrant of like tenor to such Holder;
PROVIDED, HOWEVER, in the case of mutilation, no indemnity shall be required if
this Warrant in identifiable form is surrendered to the Company for
cancellation.

11.  OFFICE OF THE COMPANY

          As long as any of the Warrants remain outstanding, the Company shall
maintain an office or agency, which may be the principal executive offices of
the Company (the "Designated Office"), where the Warrants may be presented for
exercise, registration of transfer, division or combination as provided in this
Warrant. Such Designated Office shall initially be the office of the Company at
110 East 59th Street, New York, NY 10022. The Company may from time to time
change the Designated Office to another office of the Company or its agent
within the United States by notice given to all registered holders of Warrants
at least ten (10) Business Days prior to the effective date of such change.

12.  INVESTMENT REPRESENTATIONS AND OBLIGATIONS OF HOLDER

any investment in shares of Warrant Stock upon exercise hereof).

benefit of the Registration Rights Agreement.

14.  MISCELLANEOUS

          14.1. COMMISSION REPORTS. If at any time within two years from the
date hereof, the Company is not subject to the reporting requirements of Section
13 or 15(d) of the Exchange Act, the Company shall use its reasonable best
efforts to file with the Commission (if permitted by Commission practice and
applicable laws and regulations) and provide the Holders within 15 days after it
files them with the Commission (or if not permitted, within 15 days after it
would have otherwise been required to file them with the Commission), copies of
its annual report and the information, documents and other reports that are
specified in Sections 13 and 15(d) of the Exchange Act to the extent applicable
to the Company at such time. In addition, so long as the Common Stock is
publicly traded, the Company shall furnish to the Holders, promptly upon their
becoming available, copies of the annual report to shareholders and any other
information provided by the Company to its public shareholders generally.

          14.2. NONWAIVER. No course of dealing or any delay or failure to
exercise any right hereunder on the part of the Company or the Holder shall
operate as a waiver of such right or otherwise prejudice the rights, powers or
remedies of such Person.

          14.3. NOTICE GENERALLY. Any notice, demand, request, consent,
approval, declaration, delivery or communication hereunder to be made pursuant
to the provisions of this Warrant shall be sufficiently given or made if in

     upon the exercise hereof, at its last known address appearing on the books
     of the Company maintained for such purpose; and

          (b) if to the Company, at its Designated Office,

affirmative action by the Holder to purchase shares of Common Stock, and no
enumeration herein of the rights or privileges of the Holder hereof, shall give

stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

          14.5. REMEDIES. Each holder of Warrants and/or Warrant Stock, in
addition to being entitled to exercise its rights granted by law, including
recovery of damages, shall be entitled to specific performance of its rights
provided under this Warrant. The Company agrees that monetary damages would not
be adequate compensation for any loss incurred by reason of a breach by it of
the provisions of this Warrant and hereby agrees, in an action for specific
performance, to waive the defense that a remedy at law would be adequate.

          14.6. SUCCESSORS AND ASSIGNS. Subject to the provisions of Sections
3.1, 8.1 and 8.2, this Warrant and the rights evidenced hereby shall inure to
the benefit of and be binding upon the successors of the Company and the

Stock issued upon the exercise hereof (including permitted transferees), and
shall be enforceable by any such holder.

          14.7. AMENDMENT. This Warrant and all other Warrants may be modified
or amended or the provisions hereof waived with the written consent of the
Company and the Majority Warrant Holders; PROVIDED THAT no such Warrant may be
modified or amended to reduce the number of shares of Common Stock for which
such Warrant is exercisable or to increase the price at which such shares may be
purchased upon exercise of such Warrant (before giving effect to any adjustment
as provided therein) without the written consent of the holder thereof.

          14.8. SEVERABILITY. Wherever possible, each provision of this Warrant
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Warrant.
