                                                                     Exhibit 4.5

                         ASSET BRIDGE WARRANT AGREEMENT

         ASSET BRIDGE WARRANT AGREEMENT, dated as of February 4, 2000 (as
amended, supplemented, amended and restated or otherwise modified from time to
time, this "WARRANT AGREEMENT"), between RAILAMERICA, INC., a Delaware
corporation ("HOLDINGS"), and the purchasers set forth on the signature pages
hereto (the "PURCHASERS"). Capitalized terms used herein and not defined herein
shall have the meanings specified in the Asset Bridge Securities Purchase
Agreement described below.

                                    RECITALS

         WHEREAS, Palm Beach Rail Holding, Inc., a Delaware corporation
(together with its successors,"INTERMEDIATE HOLDINGS"), Holdings and the other
Guarantors set forth therein and the Purchasers have entered into an Asset
Bridge Securities Purchase Agreement, dated as of February 4, 2000 (as amended,
supplemented or otherwise modified, the "ASSET BRIDGE SECURITIES PURCHASE
AGREEMENT"), pursuant to which the Purchasers have agreed to purchase up to
$55,000,000 in aggregate principal amount of the Asset Bridge Senior Secured
Increasing Rate Notes (the "NOTES") of Intermediate Holdings, subject to the
terms and conditions set forth in the Asset Bridge Securities Purchase
Agreement;

         WHEREAS, as a condition precedent to the purchase of the Asset Bridge
Notes by the Purchasers, Holdings has agreed to issue, and the Purchasers are
entitled to receive (on the terms and conditions, and pursuant to the schedules,
set forth in the Asset Bridge Escrow Agreement referred to below) warrants, as
hereinafter described (the "WARRANTS"), to purchase an amount of Common Stock,
$0.001 par value per share, of Holdings (the "COMMON STOCK") or any security
substituted for the Common Stock in an amount equal to up to the percentage of
the Capital Stock of Holdings as of the Issuance Date as set forth on Schedule 1
hereto (such Common Stock being referred to herein as the "WARRANT SHARES"), at
an exercise price equal to the closing price per share of Common Stock of
Holdings traded on the NASDAQ National Market System at the close of trading on
the Issuance Date (the "EXERCISE PRICE");

         WHEREAS, Holdings has agreed that the holders of Asset Bridge Notes
shall be entitled to receive, in accordance with the Asset Bridge Escrow
Agreement, Warrants representing (x) 50% of the total Warrants placed in escrow
on the date that is 180 days following the Issuance Date, (y) 25% of the total
Warrants placed in escrow on the date that is 270 days following the Issuance
Date and (z) 25% of the total Warrants placed in escrow on the date that is 360
days following the Issuance Date; and

         WHEREAS, Holdings has agreed to execute the Warrants and deliver the
Warrants to an escrow agent on the date hereof and such escrow agent has agreed
to deliver the Warrants to the holders of Asset Bridge Notes in accordance with
an Asset Bridge Escrow Agreement dated as of February 4, 2000 (as amended,
supplemented or otherwise modified, the "ASSET BRIDGE ESCROW AGREEMENT") among
Holdings, the Purchasers and Snoga, Inc., as escrow agent.

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto agree as follows:

                                    AGREEMENT

         SECTION 1. WARRANT CERTIFICATES. The certificates evidencing the
Warrants (the "WARRANT CERTIFICATES") to be delivered pursuant to this Agreement
shall be in registered form only and shall be substantially in the form set
forth in EXHIBIT A attached hereto.

         SECTION 2. EXECUTION OF WARRANT CERTIFICATES. Warrant Certificates
shall be signed on behalf of Holdings by its chief executive officer, its
president, any vice-president, its chief financial officer or, if Holdings shall
not have a chief financial officer, its treasurer (each an "OFFICER"). Each such
signature upon the Warrant Certificates may be in the form of a facsimile
signature of the present or any future Officer and may be imprinted or otherwise
reproduced on the Warrant Certificates and for that purpose Holdings may adopt
and use the facsimile signature of any person who shall have been an Officer,
notwithstanding the fact that at the time the Warrant Certificates shall be
delivered or disposed of he shall have ceased to hold such office.

         In case any Officer of Holdings who shall have signed any of the
Warrant Certificates shall cease to be such Officer before the Warrant
Certificates so signed shall have been delivered or disposed of by Holdings,
such Warrant Certificates nevertheless may be delivered or disposed of as though
such person had not ceased to be such Officer of Holdings.

         SECTION 3. REGISTRATION. Holdings shall number and register each
Warrant Certificate in a register (the "WARRANT REGISTER") as such Warrant
Certificate is issued. Holdings may deem and treat the registered holder(s) of
the Warrant Certificates as the absolute owners thereof (notwithstanding any
notation of ownership or other writing thereon made by anyone), for all
purposes, and shall not be affected by any notice to the contrary.

         SECTION 4. REGISTRATION OF TRANSFERS AND EXCHANGES. Holdings shall from
time to time register the transfer of any outstanding Warrant Certificates in
the Warrant Register to be maintained by Holdings upon surrender thereof
accompanied by a written instrument or instruments of transfer in form
satisfactory to Holdings, duly executed by the registered holder or holders
thereof or by the duly appointed legal representative thereof or by a duly
authorized attorney. Upon any such registration of transfer, a new Warrant
Certificate shall be issued to the

                                       -2-

<PAGE>   3

transferee(s) and the surrendered Warrant Certificate shall be canceled and
disposed of by Holdings.

         The Warrant holders agree that prior to any proposed transfer of the
Warrant or of the Warrant Shares, if such transfer is not made pursuant to an
effective Registration Statement under the Securities Act, the Warrant holder
will, if requested by Holdings, deliver to Holdings:

                  (1) an investment covenant reasonably satisfactory to Holdings
         signed by the proposed transferee;

                  (2) an agreement by such transferee to the placement of the
         restrictive investment legend set forth below on the Warrant or the
         Warrant Shares;

                  (3) an agreement by such transferee that Holdings may place a
         notation in the stock books of Holdings or a "stop transfer order" with
         any transfer agent or registrar with respect to the Warrant Shares;

                  (4) an agreement by such transferee to be bound by the
         provisions of this SECTION 4 relating to the transfer of such Warrant
         or Warrant Shares; and

                  (5) an opinion of the proposed transferee's counsel
         (reasonably satisfactory to Holdings) addressed to Holdings to the
         effect that the proposed Transfer of such Asset Bridge Notes may be
         effected without registration under the Securities Act.

         The Warrant holders agree that each certificate representing Warrants
and Warrant Shares will bear the following legend:

         "THE SECURITIES EVIDENCED OR CONSTITUTED HEREBY HAVE BEEN ACQUIRED FOR
         INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED. SUCH SECURITIES MAY NOT BE SOLD, TRANSFERRED, PLEDGED
         OR HYPOTHECATED UNLESS THE REGISTRATION PROVISIONS OF SAID ACT AND ANY
         APPLICABLE STATE SECURITIES LAWS HAVE BEEN COMPLIED WITH OR UNLESS
         HOLDINGS HAS RECEIVED AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
         HOLDINGS THAT SUCH REGISTRATION IS NOT REQUIRED."

         Warrant Certificates may be exchanged at the option of the holder(s)
thereof when surrendered to Holdings at its office for another Warrant
Certificate or other Warrant Certificates of like tenor and representing in the
aggregate a like number of Warrants. Warrant Certificates surrendered for
exchange shall be canceled and disposed of by Holdings.

                                       -3-

         SECTION 5. TERMS OF WARRANTS: EXERCISE OF WARRANTS. Subject to the
terms of this Agreement, each Warrant holder shall have the right, which may be
exercised commencing at the opening of business on the relevant Exercise Date
and until 5:00 p.m. New York City time on the seventh anniversary of such
Exercise Date, to receive from Holdings the number of fully paid and
nonassessable Warrant Shares which the holder may at the time be entitled to
receive on exercise of such Warrant and payment of the Exercise Price for such
Warrant Shares. For purposes hereof, "Exercise Date" means, for any Warrant, the
date upon which such Warrant was released from escrow pursuant to the terms of
the Asset Bridge Escrow Agreement.

         A Warrant may be exercised upon surrender to Holdings at its office
designated for such purpose (the address of which is set forth in SECTION 14
hereof) of the certificate or certificates evidencing the Warrants to be
exercised with the form of election to purchase on the reverse thereof duly
filled in and signed, which signature shall be guaranteed by a bank or trust
company having an office or correspondent in the United States or a broker or
dealer which is a member of a registered securities exchange or the National
Association of Securities Dealers, Inc. (the "NASD"), and upon payment to
Holdings of the Exercise Price. Payment of the Exercise Price shall be made (i)
in cash or by certified or official bank check payable to the order of Holdings,
(ii) by tendering Warrants having a fair market value equal to the Exercise
Price or (iii) with any combination of CLAUSE (I) or (II). For purpose of CLAUSE
(II) above, the fair market value of the Warrants shall be determined as
follows: (A) to the extent the Common Stock is publicly traded and listed on the
NASDAQ National Market System, or a national securities exchange, the fair
market value shall be equal to the difference between (1) the Quoted Price of
the Common Stock on the date of exercise and (2) the Exercise Price; or (B) to
the extent the Common Stock is not publicly traded, or otherwise is not listed
on a national securities exchange, the fair market value of the Warrants shall
be equal to the difference between (1) the value per share of Common Stock as
determined in good faith by the Board of Directors of Holdings pursuant to
CLAUSE (N) of SECTION 10 and (2) the Exercise Price.

         Subject to the provisions of SECTION 6 hereof, upon such surrender of
Warrants and payment of the Exercise Price, Holdings shall issue and cause to be
delivered with all reasonable dispatch, but in no event later than three
Business Days after such surrender and payment, to or upon the written order of
the holder and in such name or names as the Warrant holder may designate, a
certificate or certificates for the number of full Warrant Shares issuable upon
the exercise of such Warrants as provided in SECTION 10; PROVIDED, that if any
consolidation, merger or lease or sale of assets is proposed to be effected by
Holdings as described in CLAUSE (M) of SECTION 10 hereof, or a tender offer or
an exchange offer for shares of Common Stock of Holdings shall be made, upon
such surrender of Warrants and payment of the Exercise Price as aforesaid,
Holdings shall, as soon as possible, but in any event not later than two
Business Days thereafter, issue and cause to be delivered the full number of
Warrant Shares issuable upon the exercise of such Warrants in the manner
described in this sentence as provided in SECTION 10. Together with the delivery
of such Warrant Shares, Holdings shall deliver a certificate of its chief
accounting or chief financial officer or, if Holdings shall not have a chief
financial officer, its

                                       -4-

<PAGE>   5

controller setting forth and certifying the calculations made by Holdings
pursuant to SECTION 10 hereof to determine the number of Warrant Shares issuable
upon the exercise of the surrendered Warrant or Warrants. Such certificate or
certificates representing Warrant Shares shall be deemed to have been issued and
any person so designated to be named therein shall be deemed to have become a
holder of record of such Warrant Shares as of the date of the surrender of such
Warrants and payment of the Exercise Price.

         The Warrants shall be exercisable, at the election of the holders
thereof, either in full or from time to time in part and, in the event that a
certificate evidencing Warrants is exercised in respect of fewer than all of the
Warrant Shares issuable on such exercise at any time prior to the date of
expiration of the Warrants, a new certificate evidencing the remaining Warrant
or Warrants will be issued and delivered pursuant to the provisions of this
Section and of SECTION 2 hereof; PROVIDED, that Warrants may not be exercised in
denominations of less than 1,000 unless the holder has fewer than 1,000
Warrants.

         All Warrant Certificates surrendered upon exercise of Warrants shall be
canceled and disposed of by Holdings.

         Holdings shall keep copies of this Agreement and any notices given or
received hereunder available for inspection by the holders during normal
business hours at its office.

         SECTION 6. PAYMENT OF TAXES. Holdings shall pay all documentary stamp
taxes attributable to the initial issuance of Warrant Shares upon the exercise
of Warrants; PROVIDED, that Holdings shall not be required to pay any tax or
taxes which may be payable in respect of any transfer involved in the issue of
any Warrant Certificates or any certificates for Warrant Shares in a name other
than that of the registered holder of a Warrant Certificate surrendered upon the
transfer or exercise of a Warrant, and Holdings shall not be required to issue
or deliver such Warrant Certificates or Warrant Shares unless or until the
person or persons requesting the issuance thereof shall have paid to Holdings
the amount of such tax or shall have established to the satisfaction of Holdings
that such tax has been paid.

         SECTION 7. MUTILATED OR MISSING WARRANT CERTIFICATES. In case any of
the Warrant Certificates shall be mutilated, lost, stolen or destroyed, Holdings
may in its discretion issue, in exchange and substitution for and upon
cancellation of the mutilated Warrant Certificate, or in lieu of and
substitution for the Warrant Certificate lost, stolen or destroyed, a new
Warrant Certificate of like tenor and representing an equivalent number of
Warrants, but only upon receipt of evidence reasonably satisfactory to Holdings
of such loss, theft or destruction of such Warrant Certificate and indemnity, if
requested, also reasonably satisfactory to it. Applicants for such substitute
Warrant Certificates shall also comply with such other reasonable regulations
and pay such other reasonable charges as Holdings may prescribe.

                                       -5-

         SECTION 8. RESERVATION OF WARRANT SHARES. Holdings shall at all times
reserve and keep available, free from preemptive rights, out of the aggregate of
its authorized but unissued Common Stock or its authorized and issued Common
Stock held in its treasury for the purpose of enabling it to satisfy any
obligation to issue Warrant Shares upon exercise of Warrants, the maximum number
of shares of Common Stock which may then be deliverable upon the exercise of all
outstanding Warrants.

         Holdings or, if appointed, the transfer agent for the Common Stock (the
"TRANSFER AGENT") and every subsequent transfer agent for any shares of
Holdings' Capital Stock issuable upon the exercise of any of the rights of
purchase aforesaid will be irrevocably authorized and directed at all times to
reserve such number of authorized shares as shall be required for such purpose.
Holdings will keep a copy of this Agreement on file with the Transfer Agent and
with every subsequent transfer agent for any shares of Holdings' Capital Stock
issuable upon the exercise of the rights of purchase represented by the
Warrants. Holdings will furnish such Transfer Agent a copy of all notices of
adjustments and certificates related thereto, transmitted to each holder
pursuant to SECTION 13 hereof.

         Before taking any action which would cause an adjustment pursuant to
SECTION 10 or 11 hereof in the Exercise Rate (as defined below), Holdings will
take any corporate action which may, in the opinion of its counsel, be necessary
in order that Holdings may validly and legally issue fully paid and
nonassessable Warrant Shares at the Exercise Rate as so adjusted.

         Holdings covenants that all Warrant Shares which may be issued upon
exercise of Warrants will, upon issue, be fully paid, nonassessable, free of
preemptive rights and free from all taxes, liens, charges and security interests
with respect to the issue thereof.

         SECTION 9. OBTAINING STOCK EXCHANGE LISTINGS. Without limiting any term
or condition of the Asset Bridge Equity Registration Rights Agreement, Holdings
will from time to time take all action which may be necessary so that the
Warrant Shares, immediately following their issuance upon the exercise of
Warrants, will be listed on the principal securities exchanges and markets
within the United States of America, if any, on which other shares of Common
Stock are then listed.

         SECTION 10. ADJUSTMENT OF NUMBER OF WARRANT SHARES ISSUABLE. The number
of Warrant Shares issuable upon the exercise of each Warrant (the "EXERCISE
RATE") is subject to adjustment from time to time upon the occurrence of the
events enumerated in this SECTION 10 and under the circumstances described in
SECTION 11. For purposes of this SECTION 10, "Common Stock" means shares now or
hereafter authorized of any class of common stock of Holdings and any other
Capital Stock of Holdings, however designated, that has the right (subject to
any prior rights of any class or series of preferred stock) to participate in
any distribution of the assets or earnings of Holdings without limit as to per
share amount.

                                       -6-

<PAGE>   7

         (a) ADJUSTMENT FOR CHANGE IN CAPITAL STOCK. If Holdings:

                  (1) pays a dividend or makes a distribution on its Common
         Stock in shares of its Common Stock;

                  (2) subdivides its outstanding shares of Common Stock into a
         greater number of shares;

                  (3) combines its outstanding shares of Common Stock into a
         smaller number of shares;

                  (4) makes a distribution on its Common Stock in shares of its
         Capital Stock other than Common Stock; or

                  (5) issues by reclassification of its Common Stock any shares
         of its Capital Stock;

then the Exercise Rate in effect immediately prior to such action shall be
proportionately adjusted so that the holder of any Warrant thereafter exercised
may receive the aggregate number and kind of shares of Capital Stock of Holdings
which he would have owned immediately following such action if such Warrant had
been exercised immediately prior to such action.

         The adjustment shall become effective immediately after the record date
in the case of a dividend or distribution and immediately after the effective
date in the case of a subdivision, combination or reclassification.

         If after an adjustment a holder of a Warrant upon exercise of such
Warrant may receive shares of two or more classes of Capital Stock of Holdings,
Holdings shall determine in good faith the allocation of the adjusted Exercise
Rate between the classes of Capital Stock. After such allocation, the exercise
privilege and the Exercise Rate of each class of Capital Stock shall thereafter
be subject to adjustment on terms comparable to those applicable to Common Stock
in this Section.

         Such adjustment shall be made successively whenever any event listed
above shall occur.

         (b) ADJUSTMENT FOR RIGHTS ISSUE. If Holdings issues any rights, options
or warrants entitling any person to subscribe for Common Stock or securities
convertible into, or exchangeable or exercisable for, Common Stock at an
offering price (or with an initial conversion, exchange or exercise price plus
such offering price) that is less than the Current Market Price per share of

                                      -7-
<PAGE>   8

Common Stock on the record date for such issuance (all of the foregoing,
"RIGHTS"), the Exercise Rate shall be adjusted in accordance with the formula:

     E' = E  x  O + N
                -----------
                     N x P
                O +  -----
                      M

where:

         E'   =   the adjusted Exercise Rate.

         E    =   the current Exercise Rate.

         O    =   the number of shares of Common Stock outstanding on
                  the record date (assuming the conversion, exercise or
                  exchange of all Rights and convertible securities
                  into shares of Common Stock).

         N    =   the number of additional shares of Common Stock
                  issuable pursuant to the Rights offered.

         P    =   the offering price plus initial conversion,
                  exchange or exercise price per share of the
                  additional shares of Common Stock issuable pursuant
                  to the Rights.

         M   =    the Current Market Price per share of Common Stock
                  on the record date.

         The adjustment shall be made successively whenever any such Rights are
issued and shall become effective immediately after the record date for the
determination of stockholders entitled to receive the Rights in the case of
Rights to be issued to the holders of Common Stock. To the extent that shares of
Common Stock are not delivered after the expiration of such Rights, the Exercise
Rate shall be readjusted to the Exercise Rate which would otherwise be in effect
had the adjustment made upon the issuance of such options, rights or warrants
been made on the basis of delivery of only the number of shares of Common Stock
actually delivered. In the event that such options, rights or warrants are not
so issued, the Exercise Rate shall again be adjusted to be the Exercise Rate
which would then be in effect if such date fixed for determination of
stockholders entitled to receive such options, rights or warrants had not been
so fixed.

         This CLAUSE (B) does not apply to:

                  (1) Rights issued to persons in a bona fide public offering
         pursuant to a firm commitment underwriting,

                  (2) Rights issued to persons who are not affiliates of
         Holdings in a bona fide private placement through a placement agent
         that is a member firm of the NASD (except to the extent that any
         discount from the Current Market Price attributable to restrictions

                                      -8-
<PAGE>   9

         on transferability of the Rights, as determined in good faith by the
         Board of Directors pursuant to CLAUSE (N) of SECTION 10 and described
         in a Board resolution, shall exceed 5%), or

                  (3) Rights issued to Holdings employees under bona fide
         employee benefit plans adopted by the Board of Directors and approved
         by the holders of Common Stock when required by law, if such Rights
         would otherwise be covered by this CLAUSE (B) (but only to the extent
         that the aggregate number of Rights excluded hereby and issued after
         the date of this Agreement shall not exceed the right to subscribe for
         more than 5% of the Common Stock then outstanding).

         (c) ADJUSTMENT FOR OTHER DISTRIBUTIONS. If Holdings distributes to all
holders of its Common Stock any of its assets (including but not limited to
cash), debt securities, preferred stock or any rights or warrants to purchase
any such securities, the Exercise Rate shall be adjusted in accordance with the
formula:

          E' = E x   M
                    ---
                    M-F

         where:

         E'  =  the adjusted Exercise Rate.

         E   =  the current Exercise Rate.

         M   =  the Current Market Price per share of Common Stock
                on the record date.

         F   =  the fair market value on the record date of the
                assets, securities, rights or warrants applicable to
                one share of Common Stock. The Board of Directors
                shall determine the fair market value pursuant to
                CLAUSE (N) of SECTION 10 based upon the trading
                prices of publicly traded securities where
                applicable.

         The adjustment shall be made successively whenever any such
distribution is made and shall become effective immediately after the record
date for the determination of stockholders entitled to receive the distribution.

         This clause does not apply to Rights referred to in CLAUSE (B) of this
SECTION 10.

         (d) ADJUSTMENT FOR COMMON STOCK ISSUE. If Holdings issues shares of
Common Stock for a consideration per share less than the Current Market Price
per share on the date Holdings

                                      -9-
<PAGE>   10
fixes the offering price of such additional shares, the Exercise Rate shall be
adjusted in accordance with the formula:

     E' = E  x  O + N
                ------------

                      N x P
                  O + -----
                        M

where:

         E'  =  the adjusted Exercise Rate.

         E   =  the then current Exercise Rate.

         O   =  the number of shares of Common Stock outstanding
                immediately prior to the issuance of such additional
                shares (assuming the conversion, exercise or exchange
                of all Rights and convertible securities into shares
                of Common Stock).

         N   =  the number of additional shares of Common Stock issued.

         P   =  the aggregate consideration received per share for
                the issuance of such additional shares of Common
                Stock.

         M   =  the Current Market Price per share of Common Stock
                on the date of issuance of such additional shares of
                Common Stock.

         The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance.

         This CLAUSE (D) does not apply to:

                  (1) any of the transactions described in CLAUSES (A), (B), (C)
         or (E) of this SECTION 10 (including transactions referred to in such
         clauses as not being subject thereto),

                  (2) the exercise of Warrants, or the conversion or exchange of
         other securities convertible or exchangeable for Common Stock,

                  (3) Common Stock issued upon the exercise of rights or
         warrants issued to the holders of Common Stock,

                                      -10-
<PAGE>   11

                  (4) Common Stock issued to stockholders of any person that is
         not affiliated with Holdings and that merges into Holdings, or with a
         subsidiary of Holdings, in proportion to their stock holdings of such
         person immediately prior to such merger, upon such merger,

                  (5) Common Stock issued to persons in a bona fide public
         offering pursuant to a firm commitment underwriting, or

                  (6) Common Stock issued to persons who are not affiliates of
         Holdings in a bona fide private placement through a placement agent
         that is a member firm of the NASD (except to the extent that any
         discount from the Current Market Price attributable to restrictions on
         transferability of the Common Stock, as determined in good faith by the
         Board of Directors pursuant to CLAUSE (N) of SECTION 10 and described
         in a Board resolution, shall exceed 5%).

         (e) ADJUSTMENT FOR CONVERTIBLE SECURITIES ISSUE. If Holdings issues any
securities convertible into or exchangeable for Common Stock (other than
securities issued in transactions described in CLAUSES (B) and (C) of this
SECTION 10) for a consideration per share of Common Stock initially deliverable
upon conversion or exchange of such securities less than the Current Market
Price per share on the date of issuance of such securities, the Exercise Rate
shall be adjusted in accordance with the formula:

          E' = E  x O + N
                    -----------

                         N x P
                     O + -----
                          M
where:

         E'  =   the adjusted Exercise Rate.

         E   =   the then current Exercise Rate.

         O   =   the number of shares of Common Stock outstanding
                 immediately prior to the issuance of such securities
                 (assuming the conversion, exercise or exchange of all
                 Rights and convertible securities into shares of
                 Common Stock).

         N   =   the maximum number of shares of Common Stock
                 deliverable upon conversion of or in exchange for
                 such securities at the initial conversion or exchange
                 rate.

         P   =   the aggregate consideration received for the
                 issuance of each such security, plus any additional
                 consideration received upon the exchange or
                 conversion of such security.

         M   =   the Current Market Price per share on the date of
                 issuance of such securities.

                                      -11-
<PAGE>   12

         The adjustment shall be made successively whenever any such issuance is
made, and shall become effective immediately after such issuance.

         If all of the Common Stock deliverable upon conversion or exchange of
such securities has not been issued when such securities are no longer
outstanding, then the Exercise Rate shall promptly be readjusted to the Exercise
Rate which would then be in effect had the adjustment upon the issuance of such
securities been made on the basis of the actual number of shares of Common Stock
issued upon conversion or exchange of such securities.

         This CLAUSE (E) does not apply to:

                  (1) convertible securities issued to stockholders of any
         person that is not affiliated with Holdings and that merges into
         Holdings, or with a subsidiary of Holdings, in proportion to their
         stock holdings of such person immediately prior to such merger, upon
         such merger,

                  (2) convertible securities issued to persons in a bona fide
         public offering pursuant to a firm commitment underwriting,

                  (3) convertible securities issued to persons who are not
         affiliates of Holdings in a bona fide private placement through a
         placement agent which is a member firm of the NASD (except to the
         extent that any discount from the Current Market Price attributable to
         restrictions on transferability of Common Stock issuable upon
         conversion, as determined in good faith by the Board of Directors
         pursuant to CLAUSE (N) of SECTION 10 and described in a Board
         resolution, shall exceed 5%), or

                  (4) convertible securities that are otherwise provided for by
         CLAUSES (A), (B), (C) or (D) of this SECTION 10.

         (f) CURRENT MARKET PRICE. The current market price per share of Common
Stock (the "CURRENT MARKET PRICE") on any date is the average of the Quoted
Prices of the Common Stock for 30 consecutive trading days commencing 45 trading
days before the date in question. The "Quoted Price" of the Common Stock is the
last reported sales price of the Common Stock as reported by NASDAQ National
Market System, or if the Common Stock is listed on a securities exchange, the
last reported sales price of the Common Stock on such exchange which shall be
for

                                      -12-
<PAGE>   13

consolidated trading if applicable to such exchange, or if neither so
reported or listed, the last reported bid price of the Common Stock. In the
absence of one or more such quotations, the Board of Directors of Holdings shall
determine the Current Market Price pursuant to CLAUSE (N) of SECTION 10 in good
faith.

         (g) CONSIDERATION RECEIVED. For purposes of any computation respecting
consideration received pursuant to CLAUSES (D) and (E) of this SECTION 10, the
following shall apply:

                  (1) in the case of the issuance of shares of Common Stock for
         cash, the consideration shall be the amount of such cash, PROVIDED that
         in no case shall any deduction be made for any commissions, discounts
         or other expenses incurred by Holdings for any underwriting of the
         issue or otherwise in connection therewith;

                  (2) in the case of the issuance of shares of Common Stock for
         a consideration in whole or in part other than cash, the consideration
         other than cash shall be deemed to be the fair market value thereof as
         determined in good faith by the Board of Directors pursuant to CLAUSE
         (N) of SECTION 10, based upon the trading prices of publicly traded
         securities where appropriate (irrespective of the accounting treatment
         thereof), and described in a resolution of the Board of Directors of
         Holdings; and

                  (3) in the case of the issuance of securities convertible into
         or exchangeable for shares, the aggregate consideration received
         therefor shall be deemed to be the consideration received by Holdings
         for the issuance of such securities plus the additional minimum
         consideration, if any, to be received by Holdings upon the conversion
         or exchange thereof (the consideration in each case to be determined in
         the same manner as provided in SUBCLAUSES (1) and (2) of this CLAUSE
         (G)).

         (h) WHEN DE MINIMIS ADJUSTMENT MAY BE DEFERRED No adjustment in the
Exercise Rate need be made unless the adjustment would require an increase or
decrease of at least 1% in the Exercise Rate. Any adjustments that are not made
shall be carried forward and taken into account in any subsequent adjustment.

         All calculations under this Section shall be made to the nearest
1/100th of a share.

         (i) WHEN NO ADJUSTMENT REQUIRED. No adjustment need be made for rights
to purchase Common Stock pursuant to a plan by Holdings for reinvestment of
dividends or interest.

         No adjustment need be made for a change in the par value or no par
value of the Common Stock.

         To the extent the Warrants become convertible into cash, no adjustment
need be made thereafter as to the cash. Interest will not accrue on the cash.

                                      -13-
<PAGE>   14

         (j) NOTICE OF ADJUSTMENT. Whenever the Exercise Rate is adjusted,
Holdings shall provide the notices required by SECTION 14 hereof.

         (k) VOLUNTARY INCREASE. Holdings from time to time may increase the
Exercise Rate by any amount for any period of time if the period is at least 20
days and if the increase is irrevocable during the period.

         Whenever the Exercise Rate is increased pursuant to this CLAUSE (K),
Holdings shall mail to Warrant holders a notice of the increase. Holdings shall
mail the notice at least 15 days before the date the increased Exercise Rate
takes effect. The notice shall state the increased Exercise Rate and the period
it will be in effect.

         An increase of the Exercise Rate pursuant to this CLAUSE (K) does not
change or adjust the Exercise Rate otherwise in effect for purposes of CLAUSES
(A), (B), (C), (D) and (E) of this SECTION 10.

         (l) NOTICE OF CERTAIN TRANSACTIONS. If:

                  (1) Holdings takes any action that would require an adjustment
         in the Exercise Rate pursuant to CLAUSES (A), (B), (C), (D) or (E) of
         this SECTION 10;

                  (2) Holdings takes any action that would require a
         supplemental Asset Bridge Warrant Agreement pursuant to CLAUSE (M) of
         this SECTION 10; or

                  (3) there is a liquidation or dissolution of Holdings,

then Holdings shall mail to Warrant holders a notice stating the proposed record
date for a dividend or distribution or the proposed effective date of a
subdivision, combination, reclassification, consolidation, merger, transfer,
lease, liquidation or dissolution. Holdings shall mail the notice at least 15
days before such date. Failure to mail the notice or any defect in it shall not
affect the validity of the transaction.

         (m) REORGANIZATION OF HOLDINGS. If Holdings consolidates or merges with
or into, or transfers or leases all or substantially all its assets to, any
person, upon consummation of such transaction the Warrants shall automatically
become exercisable for the kind and amount of securities, cash or other assets
which the holder of a Warrant would have owned immediately after the
consolidation, merger, transfer or lease if the holder had exercised the Warrant
immediately before the effective date of the transaction. Concurrently with the
consummation of such transaction, the corporation formed by or surviving any
such consolidation or merger if other than Holdings, or the person to which such
sale or conveyance shall have been made, shall enter into a supplemental Asset
Bridge Warrant Agreement so providing and further providing for adjustments
which shall be as nearly equivalent as may be practical to the adjustments

                                      -14-
<PAGE>   15

provided for in this Section. The successor company shall mail to Warrant
holders a notice describing the supplemental Asset Bridge Warrant Agreement.

         If the issuer of securities deliverable upon exercise of Warrants under
the supplemental Asset Bridge Warrant Agreement is an affiliate of the formed,
surviving, transferee or lessee corporation, that issuer shall join in the
supplemental Asset Bridge Warrant Agreement.

         If this CLAUSE (M) applies, CLAUSES (A), (B), (C), (D) and (E) of this
SECTION 10 do not apply.

         (n) HOLDINGS DETERMINATION NOT FINAL. Any determination that Holdings
or its Board of Directors must make pursuant to this Agreement shall be made in
good faith and shall be binding on the holders of Warrants, except as set forth
herein. Holdings shall give each holder of Warrants written notice of any such
determination by Holdings or its Board of Directors. If a majority of the
holders of the Warrants do not agree with any such determination by Holdings or
its Board of Directors, such holders may request, in a notice delivered to
Holdings not later than 30 days after the date on which the holders received
notice of such determination from Holdings, that such determination be made by
an independent investment banking firm (or, if an investment banking firm is
generally not qualified to render such a determination, an independent appraisal
firm) of recognized national standing chosen by Holdings, which determination
shall be final and binding on Holdings and the holders of Warrants, absent
manifest error. All fees and expenses incurred in connection with any
determination made by an independent investment banking firm or appraisal firm,
as the case might be, shall be borne by Holdings, unless such determination is
in agreement with, or more favorable to Holdings than, the determination that
was made by Holdings or its Board of Directors, in which case such fees and
expenses shall be borne by the holders that requested such determination.

         (o) WHEN ISSUANCE OR PAYMENT MAY BE DEFERRED. In any case in which this
SECTION 10 shall require that an adjustment in the Exercise Rate be made
effective as of a record date for a specified event, Holdings may elect to defer
until the occurrence of such event issuing to the holder of any Warrant
exercised after such record date the Warrant Shares and other Capital Stock of
Holdings, if any, issuable upon such exercise over and above the Warrant Shares
and other Capital Stock of Holdings, if any, issuable upon such exercise on the
basis of the Exercise Rate; PROVIDED, HOWEVER, that Holdings shall deliver to
such holder a due bill or other appropriate instrument evidencing such holder's
right to receive such additional Warrant Shares and other Capital Stock of
Holdings upon the occurrence of the event requiring such adjustment.

         (p) FORM OF WARRANTS. Irrespective of any adjustments in the Exercise
Rate or in the kind of shares purchasable upon the exercise of the Warrants,
Warrants theretofore or thereafter issued may continue to express the same price
and kind of shares as are stated in the Warrants initially issuable pursuant to
this Agreement.

                                      -15-
<PAGE>   16

         (q) EXERCISE PRICE. If following any adjustment in the Exercise Rate
pursuant to this SECTION 10, the Exercise Price per share of common stock of
Holdings shall be less than the par value of such common stock, such Exercise
Price per share of common stock shall be increased to the par value of such
stock.

         SECTION 11. NO DILUTION OR IMPAIRMENT: CAPITAL AND OWNERSHIP STRUCTURE.
If any event shall occur as to which the provisions of SECTION 10 are not
strictly applicable but the failure to make any adjustment would adversely
affect the purchase rights represented by the Warrants in accordance with the
essential intent and principles of such Section, then, in each such case,
Holdings shall appoint, at its own expense, an investment banking firm of
recognized national standing that does not have a direct or material indirect
financial interest in Holdings or any of its subsidiaries, who has not been,
and, at the time it is called upon to give independent financial advice to
Holdings, is not (and none of its directors, officers, employees, affiliates or
stockholders are) a promoter, director or officer of Holdings or any of its
subsidiaries, which shall give their opinion upon the adjustment, if any, on a
basis consistent with the essential intent and principles established in SECTION
10, necessary to preserve, without dilution, the purchase rights, represented by
this Agreement and the Warrants. Upon receipt of such opinion, Holdings will
promptly mail a copy thereof to the holders of the Warrants and shall make the
adjustments described therein.

         Holdings will not, by amendment of its certificate of incorporation or
through any consolidation, merger, reorganization, transfer of assets,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms of the Warrants,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such action as may be necessary or appropriate in order
to protect the rights of the holders of the Warrants against dilution or other
impairment. Without limiting the generality of the foregoing, Holdings (1) will
take all such action as may be necessary or appropriate in order that Holdings
may validly and legally issue fully paid and nonassessable shares of Common
Stock on the exercise of the Warrants from time to time outstanding and (2) will
not take any action which results in any adjustment of the Exercise Rate if the
total number of Warrant Shares issuable after such action upon the exercise of
all of the Warrants would exceed the total number of shares of Common Stock then
authorized by Holdings' certificate of incorporation and available for the
purposes of issue upon such exercise. A consolidation, merger, reorganization or
transfer of assets involving Holdings covered by SECTION 10(M) shall not be
prohibited by or require any adjustment under this SECTION 11.

         SECTION 12. FRACTIONAL INTERESTS. Holdings shall not be required to
issue fractional Warrant Shares on the exercise of Warrants. If more than one
Warrant shall be presented for exercise in full at the same time by the same
holder, the number of full Warrant Shares which shall be issuable upon the
exercise thereof shall be computed on the basis of the aggregate number of
Warrant Shares purchasable on exercise of the Warrants so presented. If any
fraction of a Warrant Share would, except for the provisions of this SECTION 12,
be issuable on the

                                      -16-
<PAGE>   17

exercise of any Warrants (or specified portion thereof), the number of Warrant
Shares which shall be issued by Holdings on exercise of such Warrants shall be
rounded (i) to the last previous whole number if the fraction is less than 0.5
of a Warrant Share or (ii) to the next higher whole number if the fraction is
greater than or equal to 0.5 of a Warrant Share.

         SECTION 13. NOTICES TO WARRANT HOLDERS. Upon any adjustment of the
Exercise Rate pursuant to SECTION 10, Holdings shall promptly thereafter cause
to be delivered, by first-class mail, postage prepaid, to each of the registered
holders of the Warrant Certificates at such holder's address appearing on the
Warrant Register a certificate of an Officer of Holdings setting forth the
Exercise Rate after such adjustment and setting forth in reasonable detail the
method of calculation and the facts upon which such calculations are based and
setting forth the number of Warrant Shares (or portion thereof) issuable after
such adjustment in the Exercise Rate, upon exercise of a Warrant and payment of
the Exercise Price. Where appropriate, such notice shall be given in advance and
included as a part of the notice required to be mailed under the other
provisions of this SECTION 13.

         In case:

                  (a) Holdings shall authorize the issuance to all holders of
         shares of Common Stock of rights, options or warrants to subscribe for
         or purchase shares of Common Stock or of any other subscription rights
         or warrants;

                  (b) Holdings shall authorize the distribution to all holders
         of shares of Common Stock of evidences of its indebtedness or assets
         (other than cash dividends or cash distributions payable out of
         consolidated earnings or earned surplus or dividends payable in shares
         of Common Stock or distributions referred to in CLAUSE (A) of SECTION
         10 hereof);

                  (c) of any consolidation or merger to which Holdings is a
         party and for which approval of any stockholders of Holdings is
         required, or of the conveyance or transfer of the properties and assets
         of Holdings substantially as an entirety, or of any reclassification or
         change of Common Stock issuable upon exercise of the Warrants (other
         than a change in par value, or from par value to no par value, or from
         no par value to par value, or as a result of a subdivision or
         combination), or a tender offer or exchange offer for shares of Common
         Stock;

                  (d) of the voluntary or involuntary dissolution, liquidation
         or winding up of Holdings; or

                  (e) Holdings proposes to take any action which would require
         an adjustment of the Exercise Rate pursuant to SECTION 10;

                                      -17-
<PAGE>   18

then Holdings shall cause to be given to each of the registered holders of the
Warrant Certificates at such holder's address appearing on the Warrant Register,
at least 20 days (or 10 days in any case specified in clauses (a) or (b) above)
prior to the applicable record date hereinafter specified, or promptly in the
case of events for which there is no record date, by first-class mail, postage
prepaid, a written notice stating (i) the date as of which any such subdivision,
combination or reclassification is to be made, or (ii) the date as of which the
holders of record of shares of Common Stock to be entitled to receive any such
dividends, rights, options, warrants or distribution are to be determined, or
(iii) the initial expiration date set forth in any tender offer or exchange
offer for shares of Common Stock, or (iv) the date on which any such
consolidation, merger, conveyance, transfer dissolution, liquidation or winding
up is expected to become effective or consummated, and the date as of which it
is expected that holders of record of shares of Common Stock shall be entitled
to exchange such shares for securities or other property, if any, deliverable
upon such reclassification, consolidation, merger, conveyance, transfer,
dissolution, liquidation or winding up. The failure to give the notice required
by this SECTION 13 or any delay therein shall not affect the legality or
validity of any distribution, right, option, warrant, consolidation, merger,
conveyance, transfer, dissolution, liquidation or winding up, or the vote upon
any action.

         Nothing contained in this Agreement or in any of the Warrant
Certificates shall be construed as conferring upon the holders thereof the right
to vote or to consent or to receive notice as stockholders in respect of the
meetings of stockholders or the election of Directors of Holdings or any other
matter, or any rights whatsoever as stockholders of Holdings; PROVIDED, that
each registered holder of Warrants shall be entitled to receive all notices sent
generally to stockholders, such notices to be delivered pursuant to SECTION 14
hereof at the address of such holder appearing on the Warrant Register.

         SECTION 14. NOTICES. Any notice or demand authorized by this Agreement
to be given or made by the registered holder of any Warrant Certificate to or on
Holdings shall be delivered or sent by registered, certified or express mail,
postage prepaid, return receipt requested, or given or made by facsimile, in
each case, at the address specified below Holdings' name on the signature page
to the Asset Bridge Securities Purchase Agreement, or at such other address as
shall be designated by Holdings in a written notice to the Warrant holders.
Except as otherwise provided in this Agreement, all such communications shall be
deemed to have been duly given when transmitted by facsimile (and electronic
confirmation thereof has been received) or personally delivered or, in the case
of a mailed notice, upon receipt, in each case given or addressed as aforesaid.

         Any notice pursuant to this Agreement to be given by Holdings to the
registered holder(s) of any Warrant Certificate shall be delivered or sent by
registered, certified or express mail, postage prepaid, return receipt
requested, or given or made by facsimile (and electronic confirmation thereof
has been received), in each case, at the address of such holder appearing on the
Warrant Register, or at such other address as shall be designated by such holder
in a written

                                      -18-
<PAGE>   19

notice to Holdings. Except as otherwise provided in this Agreement, all such
communications shall be deemed to have been duly given when transmitted by
facsimile or personally delivered or in the case of a mailed notice, upon
receipt, in each case given or addressed as aforesaid.

         SECTION 15. SUPPLEMENTS AND AMENDMENTS. The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions of this Agreement may not be given unless Holdings has obtained the
written consent of holders of at least a majority of the outstanding Warrant
Certificates.

         SECTION 16. SUCCESSORS. All the covenants and provisions of this
Agreement by or for the benefit of Holdings shall bind and inure to the benefit
of its respective successors and assigns hereunder.

         SECTION 17. TERMINATION. This Agreement shall terminate when all
Warrants have been exercised.

         SECTION 18. NEW YORK LAW, SUBMISSION TO JURISDICTION, WAIVER OF JURY
TRIAL. THIS AGREEMENT AND EACH WARRANT CERTIFICATE SHALL BE CONSTRUED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK. EACH PARTY
HERETO HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE UNITED STATES

COURT SITTING IN NEW YORK CITY FOR PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT
OF OR RELATING TO THIS ASSET BRIDGE WARRANT AGREEMENT OR THE TRANSACTIONS
CONTEMPLATED HEREBY. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT

OF THE VENUE OF ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT
ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT
FORUM. EACH PARTY HERETO IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY
IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS ASSET BRIDGE WARRANT
AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         SECTION 19. BENEFITS OF THIS AGREEMENT. Except as expressly set forth
herein, nothing in this Agreement shall be construed to give to any person or
corporation other than Holdings and the registered holders of the Warrant
Certificates any legal or equitable right, remedy or claim under this Agreement;
but, except as so set forth, this Agreement shall be for the sole and exclusive
benefit of Holdings and the registered holders of the Warrant Certificates.

Warrant.

         The Asset Bridge Warrant Agreement provides that upon the occurrence of
certain events the number of Warrant Shares issuable upon the exercise of each
Warrant (the "EXERCISE RATE") may, subject to certain conditions, be adjusted.
If the Exercise Rate is adjusted, the Asset Bridge Warrant Agreement provides
that the number of shares of Common Stock issuable upon the exercise of each
Warrant shall be adjusted. No fractions of a share of Common Stock will be
issued upon the exercise of any Warrant.

         Warrant Certificates, when surrendered at the office of Holdings by the
registered holder thereof in person or by legal representative or attorney duly
authorized in writing, may be exchanged, in the manner and subject to the
limitations provided in the Asset Bridge Warrant Agreement, but without payment
of any service charge, for another Warrant Certificate or Warrant Certificates
of like tenor evidencing in the aggregate a like number of Warrants.

         Upon due presentation for registration of transfer of this Warrant
Certificate at the office of Holdings, a new Warrant Certificate or Warrant
Certificates of like tenor and evidencing in the aggregate a like number of
Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided in the Asset Bridge Warrant

the U.S. Revolving Loan Commitment Amount, any Foreign Currency Revolving Loan
Commitment Amount, the Swing Line Loan Commitment Amount or the Letter of Credit
Commitment Amount on the Business Day so specified by the Company; provided,
however, that all such reductions shall require at least one Business Day's
prior notice to the Administrative Agent and be permanent, and any partial
reduction of any Commitment Amount shall be in a minimum amount of (i)
$1,000,000 and in an integral multiple of $500,000 in the case of U.S. Revolving
Loans, (ii) Aus $500,000 and in an integral multiple of Aus $100,000 in the case
of Australian Revolving Loans and (iii) Cdn $500,000 and in an integral multiple
of Cdn $100,000 in the case of Canadian Loans. Any optional or mandatory
reduction of the U.S. Revolving Loan Commitment Amount pursuant to the terms of
this Agreement which reduces the U.S. Revolving Loan Commitment Amount below the
sum of (i) the Swing Line Loan Commitment Amount and (ii) the Letter of Credit
Commitment Amount shall result in an automatic and corresponding reduction of
the Swing Line Loan Commitment Amount and/or the Letter of Credit Commitment
Amount (as directed by the Company in a notice to the Administrative Agent
delivered together with the notice of such voluntary reduction in the U.S.
Revolving Loan Commitment Amount) to an aggregate amount not in excess of the
U.S. Revolving Loan Commitment Amount, as so reduced, without any further action
on the part of the Swing Line Lender or any Issuer.

         SECTION 2.2.2. Mandatory. Following the prepayment in full of the Term
Loans, the U.S. Revolving Loan Commitment Amount shall, without any further
action, automatically and permanently be reduced on the date the Term Loans
would otherwise have been required to be prepaid pursuant to clauses (f), (g) or
(h) of Section 3.1.1, in an amount equal to the amount by which the Term Loans
would otherwise be required to be prepaid if Term Loans had been outstanding;
provided, however, the U.S. Revolving Loan Commitment Amount shall not be
required to be mandatorily reduced if any such reduction would cause the U.S.
Revolving Loan Commitment Amount to be less than $25,000,000.

         SECTION 2.3. Borrowing Procedures. Loans (other than Swing Line Loans)
shall be made by the Lenders in accordance with Section 2.3.1, and Swing Line
Loans shall be made by the Swing Line Lender in accordance with Section 2.3.2.

         SECTION 2.3.1. Borrowing Procedure. In the case of Loans other than
Swing Line Loans, by delivering a Borrowing Request to the Administrative Agent
on or before 10:00 a.m. on a Business Day (and, in the case of Canadian Loans,
to the Canadian office of the Administrative Agent and, in the case of
Australian Revolving Loans, to the Australian Lenders), the applicable Borrower
may from time to time irrevocably request, on not less than one Business Day's
notice in the case of Base Rate Loans, or three Business Days' notice in the
case of LIBO Rate Loans or Canadian BAs, and in either case not more than five
Business Days' notice, that a Borrowing be made (a), in the case of LIBO Rate
Loans, in a minimum amount of (i) $500,000 and an integral multiple of $100,000
in the case of U.S. Loans and (ii) Aus $500,000 and in an integral multiple of
Aus $100,000 in the case of Australian Revolving Loans and (b), in the case of
Base Rate Loans, in a minimum amount of (i) $500,000 and an integral multiple of
$100,000 in the case of U.S. Loans and (ii) Cdn $500,000 and in an integral
multiple of Cdn $100,000 in the case of Canadian Loans or, in either case, in
the unused amount of the applicable Commitment; provided, however, that all of
the initial Loans shall be made as Base Rate Loans. On the terms and subject to
the conditions of this Agreement, each Borrowing shall be comprised of the type
of Loans, and shall be made on the Business Day, specified in such Borrowing
Request. In the case of Loans other than Swing Line Loans, Canadian Loans and
Australian Revolving Loans, on or before 11:00 a.m. on such Business Day each
Lender that has a Commitment to make the Loans being requested shall deposit
with the Administrative Agent same day funds in an amount equal to such Lender's
Percentage of the requested Borrowing. Such deposit will be made to an account
which the Administrative Agent shall specify from time to time by notice to the
Lenders. To the extent funds are received from the Lenders, the Administrative
Agent shall make such funds available to the applicable Borrower by wire
transfer to the accounts such Borrower shall have specified in its Borrowing
Request. No Lender's obligation to make any Loan shall be affected by any other
Lender's failure to make any Loan. The Canadian Lenders will on or before 11:00
a.m. or such Business Day, severally and not jointly, make an amount of such
Lender's Percentage of the requested Borrowing available to the Canadian
Borrower as directed in the relevant Borrowing Request. The Australian Lenders
will on or before 11:00 a.m. or such Business Day, severally and not jointly,
make an amount of such Lender's Percentage of the requested Borrowing available
to the Australian Borrower as directed in the relevant Borrowing Request.

         SECTION 2.3.2. Swing Line Loans. (a) By telephonic notice to the Swing
Line Lender on or before 12:00 noon on a Business Day (followed (within one
Business Day) by the delivery of a confirming Borrowing Request), the Company
may from time to time irrevocably request that Swing Line Loans be made by the
Swing Line Lender in an aggregate minimum principal amount of $500,000 and an
integral multiple of $100,000. All Swing Line Loans shall be made as Base Rate
Loans and shall not be entitled to be converted into LIBO Rate Loans. The
proceeds of each Swing Line Loan shall be made available by the Swing Line
Lender to the Company by wire transfer to the account the Company shall have
specified in its notice therefor by the close of business on the Business Day
telephonic notice is received by the Swing Line Lender.

                                      -52-
<PAGE>   53

         (b) If (i) any Swing Line Loan shall be outstanding for more than four
Business Days, (ii) any Swing Line Loan is or will be outstanding on a date when
the Company requests that a U.S. Revolving Loan be made, or (iii) any Default
shall occur and be continuing, then each U.S. Revolving Loan Lender (other than
the Swing Line Lender) irrevocably agrees that it will, at the request of the
Swing Line Lender, make a U.S. Revolving Loan (which shall initially be funded
as a Base Rate Loan) in an amount equal to such Lender's U.S. Revolving Loan
Percentage of the aggregate principal amount of all such Swing Line Loans then
outstanding (such outstanding Swing Line Loans hereinafter referred to as the
"Refunded Swing Line Loans"). On or before 11:00 a.m. on the first Business Day
following receipt by each U.S. Revolving Loan Lender of a request to make U.S.
Revolving Loans as provided in the preceding sentence, each U.S. Revolving Loan
Lender shall deposit in an account specified by the Swing Line Lender the amount
so requested in same day funds and such funds shall be applied by the Swing Line
Lender to repay the Refunded Swing Line Loans. At the time the U.S. Revolving
Loan Lenders make the above referenced U.S. Revolving Loans, the Swing Line
Lender shall be deemed to have made, in consideration of the making of the
Refunded Swing Line Loans, U.S. Revolving Loans in an amount equal to the Swing
Line Lender's U.S. Revolving Loan Percentage of the aggregate principal amount
of the Refunded Swing Line Loans. Upon the making (or deemed making, in the case
of the Swing Line Lender) of any U.S. Revolving Loans pursuant to this clause,
the amount so funded shall become outstanding under such U.S. Revolving Loan
Lender's U.S. Revolving Note and shall no longer be owed under the Swing Line
Note. All interest payable with respect to any U.S. Revolving Loans made (or
deemed made, in the case of the Swing Line Lender) pursuant to this clause shall
be appropriately adjusted to reflect the period of time during which the Swing
Line Lender had outstanding Swing Line Loans in respect of which such U.S.
Revolving Loans were made. Each U.S. Revolving Loan Lender's obligation to make
the U.S. Revolving Loans referred to in this clause shall be absolute and
unconditional and shall not be affected by any circumstance, including (i) any
set-off, counterclaim, recoupment, defense or other right which such Lender may
have against the Swing Line Lender, any Obligor or any Person for any reason
whatsoever; (ii) the occurrence or continuance of any Default; (iii) any adverse
change in the condition (financial or otherwise) of any Obligor; (iv) the
acceleration or maturity of any Obligations or the termination of any Commitment
after the making of any Swing Line Loan; (v) any breach of any Loan Document by
any Person; or (vi) any other circumstance, happening or event whatsoever,
whether or not similar to any of the foregoing.

         SECTION 2.4. Continuation and Conversion Elections. By delivering a
Continuation/Conversion Notice to the Administrative Agent on or before 11:00
a.m., New York time at its applicable office, on a Business Day, a Borrower may
from time to time irrevocably elect, on not less than one Business Day's notice
(in the case of a conversion of LIBO Rate Loans into Base Rate Loans) or three
Business Days' notice (in the case of a continuation of LIBO Rate Loans or a
conversion of Base Rate Loans into LIBO Rate Loans) nor more than five Business
Days' notice (in the case of any Loans) that all, or any portion in a minimum
amount of $500,000 or any larger integral multiple of $100,000 in the case of
any Borrowing of LIBO Rate Loans be, in the case of Base Rate Loans, converted
into LIBO Rate Loans or, in the case of LIBO Rate Loans, continued as LIBO Rate
Loans or, in the case of U.S. Loans only, converted to Base Rate Loans;
provided, however, that, in the absence of delivery of a Continuation/Conversion
Notice

                                      -53-
<PAGE>   54

with respect to any Loan that is a LIBO Rate Loan at least three Business Days
before the last day of the then current Interest Period with respect thereto,
such LIBO Rate Loan shall, (A) in the case of a LIBO Rate Loan that is an
Australian Revolving Loan, automatically be continued as a LIBO Rate Loan with
an Interest Period of one month and (B) in the case of a LIBO Rate Loan that is
a U.S. Loan automatically convert to a Base Rate Loan, in each case on such last
day; provided, further, however, that (x) each such conversion or continuation
shall be pro rated among the applicable outstanding Loans of the relevant
Lenders, and (y) no portion of the outstanding principal amount of any Loans may
be continued as, or be converted into, LIBO Rate Loans when any Default has
occurred and is continuing.

         SECTION 2.4.1. Converting Canadian Prime Rate Loans to, or Continuing
Canadian BAs as, Canadian BAs. Provided that the Canadian Borrower has, by
delivering a Continuation/Conversion Notice to the Canadian office of the
Administrative Agent on or before 11:00 a.m., New York time at the
Administrative Agent's office for Canadian Loans, not less than three and not
more than five Business Days before the date on which drafts are to be accepted,
requested the Canadian Lenders to accept its drafts to replace all or a portion
of an outstanding Canadian Loan, then each Canadian Lender shall, on the date of
conversion or continuation, as applicable, and concurrent with the payment by
the Canadian Borrower to the Canadian Lenders of an amount equal to the
difference between the principal or face amount of such outstanding Canadian
Loan or the portion thereof which is being converted or continued and the
aggregate Notional BA Proceeds with respect to the aggregate face amount equal
to its Percentage of the aggregate principal or face amount of such Canadian
Loan or the portion thereof which is being converted or continued, such
acceptance to be in accordance with Section 2.8.

         SECTION 2.4.2. Converting Canadian BAs to Canadian Prime Rate
Loans. Each applicable Canadian Lender shall, at the end of an Interest Period
with respect to Canadian BAs which such Lender has accepted, pay to the holder
thereof the face amount of such Canadian BA. If the Canadian Borrower has, by
delivering a Continuation/Conversion Notice to the Canadian office of the
Administrative Agent on or before 11:00 a.m., New York time at the Administra-
tive Agent's office for Canadian Loans, not less than three nor more than five
Business Days before the end of an Interest Period, requested a Canadian Lender
to convert all or a portion of outstanding maturing Canadian BAs into a Canadian
Prime Rate Loan, or if the Canadian Borrower has failed to deliver a
Continuation/Conversion Notice pursuant to Section 2.4.1 or this Section 2.4.2,
such Lender shall, upon the end of the current Interest Period with respect to
such Canadian BAs and the payment by such Lender to the holders of such Canadian
BAs of the aggregate face amount thereof, be deemed to have made to the Canadian
Borrower the Canadian Prime Rate Loan into which the matured Canadian BAs or a
portion thereof are converted in the aggregate principal amount equal to its
Percentage of the aggregate face amount of the matured Canadian BAs or the
portion thereof which are being converted.

         SECTION 2.5. Funding. Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its foreign branches or Affiliates (or an international banking facility
created by such Lender) to make or maintain such LIBO Rate Loan; provided,
however, that such LIBO Rate Loan shall nonetheless be deemed to

                                      -54-
<PAGE>   55

have been made and to be held by such Lender, and the obligation of a Borrower
to repay such LIBO Rate Loan shall nevertheless be to such Lender for the
account of such foreign branch, Affiliate or international banking facility. In
addition, each Borrower hereby consents and agrees that, for purposes of any
determination to be made for purposes of Sections 4.1, 4.2, 4.3 or 4.4, it shall
be conclusively assumed that each Lender elected to fund all LIBO Rate Loans by
purchasing U.S. Dollar deposits in its LIBOR Office's interbank eurodollar
market. Canadian Loans shall be funded by the Canadian Lenders from their
offices specified for Canadian Loans. Australian Revolving Loans shall be funded
by the Australian Lenders from their offices specified for Australian Revolving
Loans.

         SECTION 2.6. Issuance Procedures. By delivering to the Administrative
Agent an Issuance Request on or before 10:00 a.m. on a Business Day, the Company
may from time to time irrevocably request on not less than three nor more than
ten Business Days' notice, in the case of an initial issuance of a Letter of
Credit and not less than three Business Days' prior notice, in the case of a
request for the extension of the Stated Expiry Date of a standby Letter of
Credit (in each case, unless a shorter notice period is agreed to by the Issuer,
in its sole discretion), that an Issuer issue, or extend the Stated Expiry Date
of, a Letter of Credit in such form as may be requested by the Company and
approved by such Issuer, solely for the purposes described in Section 7.1.7.
Each Letter of Credit shall by its terms be stated to expire on a date (its
"Stated Expiry Date") no later than the earlier to occur of (i) the Revolving
Loan Commitment Termination Date or (ii) (unless otherwise agreed to by an
Issuer, in its sole discretion), one year from the date of its issuance. Each
Issuer will make available to the beneficiary thereof the original of the Letter
of Credit which it issues. Each Letter of Credit shall only be denominated in
U.S. Dollars.

         SECTION 2.6.1. Other Lenders' Participation Participation. Upon the
issuance of each Letter of Credit, and without further action, each U.S.
Revolving Loan Lender (other than such Issuer) shall be deemed to have
irrevocably purchased, to the extent of its Percentage to make U.S. Revolving
Loans, a participation interest in such Letter of Credit (including the
Contingent Liability and any Reimbursement Obligation with respect thereto), and
such U.S. Revolving Loan Lender shall, to the extent of its Percentage to make
U.S. Revolving Loans, be responsible for reimbursing within one Business Day the
Issuer for Reimbursement Obligations which have not been reimbursed by the
Company in accordance with Section 2.6.3. In addition, such U.S. Revolving Loan
Lender shall, to the extent of its Percentage to make U.S. Revolving Loans, be
entitled to receive a ratable portion of the Letter of Credit fees payable
pursuant to Section 3.3.3 with respect to each Letter of Credit (other than the
issuance fees payable to an Issuer of such Letter of Credit pursuant to the last
sentence of Section 3.3.3) and of interest payable pursuant to Section 3.2 with
respect to any Reimbursement Obligation. To the extent that any U.S. Revolving
Loan Lender has reimbursed any Issuer for a Disbursement, such Lender shall be
entitled to receive its ratable portion of any amounts subsequently received
(from the Company or otherwise) in respect of such Disbursement.

         SECTION 2.6.2. Disbursements. An Issuer will notify the Company and the
Administrative Agent promptly of the presentment for payment of any Letter of
Credit issued by such Issuer, together with notice of the date (the
"Disbursement Date") such payment shall be made (each such payment, a
"Disbursement"). Subject to the terms and provisions of such Letter of

                                      -55-
<PAGE>   56

Credit and this Agreement, the applicable Issuer shall make such payment to the
beneficiary (or its designee) of such Letter of Credit. Prior to 11:00 a.m. on
the first Business Day following the Disbursement Date, the Company will
reimburse the Administrative Agent, for the account of the applicable Issuer,
for all amounts which such Issuer has disbursed under such Letter of Credit,
together with interest thereon at a rate per annum equal to the rate per annum
then in effect for Base Rate Loans (with the then Applicable Margin for U.S.
Revolving Loans accruing on such amount) pursuant to Section 3.2 for the period
from the Disbursement Date through the date of such reimbursement. Without
limiting in any way the foregoing and notwithstanding anything to the contrary
contained herein or in any separate application for any Letter of Credit, the
Company hereby acknowledges and agrees that it shall be obligated to reimburse
the applicable Issuer upon each Disbursement of a Letter of Credit, and it shall
be deemed to be the obligor for purposes of each such Letter of Credit issued
hereunder (whether the account party on such Letter of Credit is the Company or
a Subsidiary Guarantor).

         SECTION 2.6.3. Reimbursement. The obligation (a "Reimbursement
Obligation") of the Company under Section 2.6.2 to reimburse an Issuer with
respect to each Disbursement (including interest thereon), and, upon the failure
of the Company to reimburse an Issuer, each U.S. Revolving Loan Lender's
obligation under Section 2.6.1 to reimburse an Issuer, shall be absolute and
unconditional under any and all circumstances and irrespective of any setoff,
counterclaim or defense to payment which the Company or such U.S. Revolving
Loan Lender, as the case may be, may have or have had against such Issuer or
any Lender, including any defense based upon the failure of any Disbursement to
conform to the terms of the applicable Letter of Credit (if, in such Issuer's
good faith opinion, such Disbursement is determined to be appropriate) or any
non-application or misapplication by the beneficiary of the proceeds of such
Letter of Credit; provided, however, that after paying in full its Reimbursement
Obligation hereunder, nothing herein shall adversely affect the right of the
Company or such Lender, as the case may be, to commence any proceeding against
an Issuer for any wrongful Disbursement made by such Issuer under a Letter of
Credit as a result of acts or omissions constituting gross negligence or wilful
misconduct on the part of such Issuer.

         SECTION 2.6.4. Deemed Disbursements. Upon the occurrence and during the
continuation of any Default under Section 8.1.9 or upon notification by the
Administrative Agent (acting at the direction of the Required Lenders) to the
Company of its obligations under this Section, following the occurrence and
during the continuation of any other Event of Default,

                  (a) the aggregate Stated Amount of all Letters of Credit
         shall, without demand upon or notice to the Company or any other
         Person, be deemed to have been paid or disbursed by the Issuers of such
         Letters of Credit (notwithstanding that such amount may not in fact
         have been paid or disbursed); and

                  (b) the Company shall be immediately obligated to reimburse
         the Issuers for the amount deemed to have been so paid or disbursed by
         such Issuers.

                                      -56-
<PAGE>   57

Amounts payable by the Company pursuant to this Section shall be deposited in
immediately available funds with the Administrative Agent and held as collateral
security for the Reimbursement Obligations. When all Defaults giving rise to the
deemed disbursements under this Section have been cured or waived the
Administrative Agent shall return to the Company all amounts then on deposit
with the Administrative Agent pursuant to this Section which have not been
applied to the satisfaction of the Reimbursement Obligations.

         SECTION 2.6.5. Nature of Reimbursement Obligations. The Company, each
other Obligor and, to the extent set forth in Section 2.6.1, each U.S. Revolving
Loan Lender shall assume all risks of the acts, omissions or misuse of any
Letter of Credit by the beneficiary thereof. No Issuer (except to the extent of
its own gross negligence or wilful misconduct) shall be responsible for:

                  (a) the form, validity, sufficiency, accuracy, genuineness or
         legal effect of any Letter of Credit or any document submitted by any
         party in connection with the application for and issuance of a Letter
         of Credit, even if it should in fact prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged;

                  (b) the form, validity, sufficiency, accuracy, genuineness or
         legal effect of any instrument transferring or assigning or purporting
         to transfer or assign a Letter of Credit or the rights or benefits
         thereunder or the proceeds thereof in whole or in part, which may prove
         to be invalid or ineffective for any reason;

                  (c) failure of the beneficiary to comply fully with conditions
         required in order to demand payment under a Letter of Credit;

                  (d) errors, omissions, interruptions or delays in transmission
         or delivery of any messages, by mail, cable, telegraph, telex or
         otherwise; or

                  (e) any loss or delay in the transmission or otherwise of any
         document or draft required in order to make a Disbursement under a
         Letter of Credit.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to any Issuer or any U.S. Revolving Loan Lender
hereunder. In furtherance and not in limitation or derogation of any of the
foregoing, any action taken or omitted to be taken by an Issuer in good faith
(and not constituting gross negligence or willful misconduct) shall be binding
upon each Obligor and each such Secured Party, and shall not put such Issuer
under any resulting liability to any Obligor or any Secured Party, as the case
may be.

         SECTION 2.7. Register; Notes. (a) Each Lender may maintain in
accordance with its usual practice an account or accounts evidencing the
Indebtedness of each Borrower to such Lender resulting from each Loan made by
such Lender, including the amounts of principal and interest payable and paid
to such Lender from time to time hereunder. In the case of a Lender that does
not request, pursuant to clause (c) below, execution and delivery of a Note
evidencing the

                                      -57-

<PAGE>   58

Loans made by such Lender to such Borrower, such account or accounts shall, to
the extent not inconsistent with the notations made by the Administrative Agent
in the Register, be conclusive and binding on such Borrower absent manifest
error; provided, however, that the failure of any Lender to maintain such
account or accounts shall not limit or otherwise affect any Obligations of the
Borrower or any other Obligor.

         (b) Each Borrower hereby designates the Administrative Agent to serve
as such Borrower's agent, solely for the purpose of this clause (b), to maintain
a register (the "Register") on which the Administrative Agent will record each
Lender's Commitments, the Loans made by each Lender and each repayment in
respect of the principal amount of the Loans of each Lender and annexed to which
the Administrative Agent shall retain a copy of each Lender Assignment Agreement
delivered to the Administrative Agent pursuant to Section 11.11.1. Failure to
make any recordation, or any error in such recordation, shall not affect such
Borrower"s obligation in respect of such Loans. The entries in the Register
shall be conclusive, in the absence of manifest error, and the applicable
Borrower, the Administrative Agent and the Lenders shall treat each Person in
whose name a Loan (and as provided in clause (c) the Note evidencing such Loan,
if any) is registered as the owner thereof for all purposes of this Agreement,
notwithstanding notice or any provision herein to the contrary. A Lender's
Commitment and the Loans made pursuant thereto may be assigned or otherwise
transferred in whole or in part only by registration of such assignment or
transfer in the Register. Any assignment or transfer of a Lender's Commitment or
the Loans made pursuant thereto shall be registered in the Register only upon
delivery to the Administrative Agent of a Lender Assignment Agreement duly
executed by the assignor thereof. No assignment or transfer of a Lender"s
Commitment or the Loans made pursuant thereto shall be effective unless such
assignment or transfer shall have been recorded in the Register by the
Administrative Agent as provided in this Section.

         (c) Each Borrower agrees that, upon the request to the Administrative
Agent by any Lender, the applicable Borrower will execute and deliver to such
Lender, as applicable, a U.S. Revolving Note, a Canadian Revolving Note, an
Australian Revolving Note, a Term A Note, a Term B Note and a Swing Line Note,
as the case may be, evidencing the Loans made by such Lender. Each Borrower
hereby irrevocably authorizes each Lender to make (or cause to be made)
appropriate notations on the grid attached to such Lender"s Notes (or on any
continuation of such grid), which notations, if made, shall evidence, inter
alia, the date of, the outstanding principal amount of, and the interest rate
and Interest Period applicable to the Loans evidenced thereby. Such notations
shall, to the extent not inconsistent with the notations made by the
Administrative Agent in the Register, be conclusive and binding on such Borrower
absent manifest error; provided, however, that the failure of any Lender to make
any such notations or any error in any such notations shall not limit or
otherwise affect any Obligations of such Borrower or any other Obligor. The
Loans evidenced by any such Note and interest thereon shall at all times
(including after assignment pursuant to Section 11.11.1) be represented by one
or more Notes payable to the order of the payee named therein and its registered
assigns. A Note and the obligation evidenced thereby may be assigned or
otherwise transferred in whole or in part only by registration of such
assignment or transfer of such Note and the obligation evidenced thereby in the
Register (and each Note shall expressly so provide). Any assignment or transfer
of all or part of an obligation evidenced by a

                                      -58-
<PAGE>   59

Note shall be registered in the Register only upon surrender for registration of
assignment or transfer of the Note evidencing such obligation, accompanied by a
Lender Assignment Agreement duly executed by the assignor thereof, and
thereupon, if requested by the assignee, one or more new Notes shall be issued
to the designated assignee and the old Note shall be returned by the
Administrative Agent to the applicable Borrower marked "exchanged". No
assignment of a Note and the obligation evidenced thereby shall be effective
unless it shall have been recorded in the Register by the Administrative Agent
as provided in this Section.

         SECTION 2.8. Canadian BAs. Not in limitation of any other provision of
this Agreement, but in furtherance thereof, the provisions of this Section 2.8
shall further apply to the acceptance, rolling over and conversion of Canadian
BAs.

         SECTION 2.8.1. Funding of Canadian BAs. If the Canadian office of the
Administrative Agent receives a Borrowing Request or a Continuation/Conversion
Notice from the Canadian Borrower requesting a Borrowing or a rollover of, or a
conversion into, a Canadian Loan by way of Canadian BAs, the Administrative
Agent shall notify each of the applicable Lenders, prior to 11:00 a.m., Toronto
time, on the second Business Day prior to the date of such Credit Extension, of
such request and of each such Lender's Percentage of such Canadian Loan. Each
applicable Lender shall, not later than 11:00 a.m., Toronto time, on the date of
each Canadian Loan by way of Canadian BAs (whether in respect of the Credit
Extension or pursuant to a rollover or conversion), accept drafts of the
Canadian Borrower which are presented to it for acceptance and which have an
aggregate face amount equal to such Lender's Percentage of the total Credit
Extension being made available by way of Canadian BAs on such date. With respect
to each drawdown of, rollover of or conversion into Canadian BAs, each such
Lender shall not be required to accept any draft which has a face amount which
is not in a minimum amount of Cdn $500,000 and in an integral multiple of Cdn
$100,000. Concurrent with the acceptance of drafts of the Canadian Borrower as
aforesaid, each applicable Lender shall, upon fulfillment by the Canadian
Borrower of the terms and conditions set forth in Article V, severally and not
jointly, make available to the Canadian Borrower as set forth in the relevant
Borrowing Request the aggregate Notional BA Proceeds with respect to the
Canadian BAs being purchased by such Lender (net of the aggregate amount
required to repay such Lender's outstanding Canadian BAs that are maturing on
such date and/or Canadian Prime Rate Loans of such Lender that are being
converted on such date). Each Canadian BA to be accepted by any Lender shall be
accepted by such Lender at its Domestic Office located in Canada.

         SECTION 2.8.2. Acceptance Fees. With respect to each draft of the
Canadian Borrower accepted pursuant hereto, the Canadian Borrower shall pay to
the Canadian Lenders, in advance, an acceptance fee calculated at the rate per
annum, on the basis of a year of 365 days or 366 days, as the case may be, equal
to the Applicable Canadian BA Stamping Fee on the face amount of such Canadian
BA for its term, being the actual number of days in the period commencing on the
date of acceptance of the Canadian Borrower's draft and continuing to (but
excluding) the maturity date of such Canadian BA. Such acceptance fee shall be
non-refundable and shall be fully earned when due. Such acceptance fee shall be
paid to the Canadian Lenders by deducting the amount thereof

                                      -59-

from what would otherwise be Notional BA Proceeds (excluding such fee) funded
pursuant to Section 2.8.1.

         SECTION 2.8.3. Execution of Canadian BAs. (a) To facilitate the
acceptance of Canadian BAs hereunder, the Canadian Borrower hereby appoints each
Canadian Lender as its attorney to sign and endorse on its behalf, in accordance
with clause (d) of Section 2.8.3, an appropriate number of drafts in the form
prescribed by that Canadian Lender.

         (b) Each Canadian Lender may, at its option, execute any draft in
handwriting or by the facsimile or mechanical signature of any of its authorized
officers, and the Canadian Lenders are hereby authorized to accept or pay, as
the case may be, any draft of the Canadian Borrower which purports to bear such
a signature notwithstanding that any such individual has ceased to be an
authorized officer of the Canadian Lender.

         (c) Any draft or Canadian BA signed by a Canadian Lender as attorney
for the Canadian Borrower whether signed in handwriting or by the facsimile or
mechanical signature of an authorized officer of a Canadian Lender, may be dealt
with by the Agent or any Lender to all intents and purposes and shall bind the
Canadian Borrower as if duly signed and issued by the Canadian Borrower.

         (d) The receipt by the Administrative Agent of a request for a Credit
Extension by way of Canadian BAs shall be each Canadian Lender's sufficient
authority to execute, and each Canadian Lender shall, subject to the terms and
conditions of this Agreement, execute drafts in accordance with such request and
the advice of the Administrative Agent pursuant to Section 2.8.1, and the drafts
so executed shall thereupon be deemed to have been presented for acceptance.

         SECTION 2.8.4. Special Provisions Relating to Acceptance Notes. (a) The
Canadian Borrower and each applicable Lender hereby acknowledge and agree that
from time to time certain Lenders which are not Canadian chartered banks or
which are Canadian chartered banks listed on Schedule II of the Bank Act
(Canada) may not be authorized to or may, as a matter of general corporate
policy, elect not to accept Canadian BA drafts, and the Canadian Borrower and
each applicable Lender agrees that any such Lender may purchase Acceptance Notes
of the Canadian Borrower in accordance with the provisions of Section 2.8.4(b)
in lieu of accepting Canadian BAs for its account.

         (b) In the event that any Lender described in Section 2.8.4(a) above is
unable to, or elects as a matter of general corporate policy not to, accept
Canadian BAs hereunder, such Lender shall not accept Canadian BAs hereunder, but
rather, if the Canadian Borrower requests the acceptance of such Canadian BAs,
the Canadian Borrower shall deliver to such Lender non-interest bearing
promissory notes (each, an "Acceptance Note") of the Canadian Borrower,
substantially in the form of Exhibit A-5 hereto, having the same maturity as the
Canadian BAs that would otherwise be accepted by such Lender and in an aggregate
principal amount equal to the undiscounted face amount of such Canadian BAs.
Each such Lender hereby agrees to purchase each Acceptance Note from the
Canadian Borrower at a purchase price equal to the Notional BA Proceeds for a
Lender

                                      -60-
<PAGE>   61

listed on Schedule II to the Bank Act (Canada) which would have been applicable
if a Canadian BA draft had been accepted by such bank and such Acceptance Notes
shall be governed by the provisions of this Article II as if they were Canadian
BAs.

         SECTION 3.1 Repayments and Prepayments; Application. The Borrowers
agree that the Loans shall be repaid and prepaid pursuant to the following
terms.

         SECTION 3.1.1. Repayments and Prepayments. Each Borrower shall repay in

prepayments of Loans shall or may be made as set forth below.

                  (a) From time to time on any Business Day, the Borrowers may
         make a voluntary prepayment, in whole or in part, of the outstanding

                           (i) Loans (other than Swing Line Loans and Canadian
                  BAs); provided, however, that (A) any such prepayment of Term
                  A Loans and Term B Loans shall be made pro rata among Term A
                  Loans and Term B Loans of the same type and, if applicable,
                  having the same Interest Period of all Lenders that have made
                  such Term A Loans or Term B Loans (applied to the remaining
                  amortization payments for the Term A Loans and the Term B
                  Loans, as the case may be, in such amounts as the Company
                  shall determine) and any such prepayment of Revolving Loans
                  shall be made pro rata among the Revolving Loans of the same
                  type and, if applicable, having the same Interest Period of
                  all Lenders that have made such Revolving Loans; (B) all such
                  voluntary prepayments shall require at least one but no more
                  than five Business Days' prior written notice to the
                  Administrative Agent; and (C) all such voluntary partial
                  prepayments shall be, in the case of (I) LIBO Rate Loans, in
                  an aggregate minimum amount of (A) $500,000 and an integral
                  multiple of $100,000 in the case of U.S. Loans and (B) Aus
                  $500,000 and in an integral multiple of Aus $100,000 in the
                  case of Australian Revolving Loans and, (II) in the case of
                  Base Rate Loans, in an aggregate minimum amount of (A)
                  $500,000 and an integral multiple of $100,000 in the case of
                  U.S. Loans and (B) Cdn $500,000 and in an integral multiple of
                  Cdn $100,000 in the case of Canadian Loans; and

                           (ii) Swing Line Loans; provided, that (A) all such
                  voluntary prepayments shall require prior telephonic notice to
                  the Swing Line Lender on or before 1:00 p.m. on the day of
                  such prepayment (such notice to be confirmed in writing within
                  24 hours thereafter); and (B) all such voluntary partial
                  prepayments shall be in an aggregate minimum amount of
                  $500,000 and an integral multiple of $100,000.

         In addition, from time to time on any Business Day, the Canadian
         Borrower may, upon not less than one Business Day's notice to the
         Administrative Agent, elect to deposit with the Administrative Agent
         Canadian Dollars in immediately available funds to be held by the
         Administrative Agent, pursuant to collateral arrangements satisfactory
         to it, for application to the payment of Canadian BAs designated by the
         Canadian Borrower in such notice (provided that any such designation
         shall be made pro rata among the Canadian Lenders on the basis of the
         aggregate face amount of Canadian BAs then outstanding). If such a
         deposit is made, then such Canadian BAs shall (to the extent of such
         deposit) be deemed no longer outstanding for purposes of this
         Agreement.

                  (b) On each date when the sum of (i) the aggregate outstanding
         principal amount of all U.S. Revolving Loans and Swing Line Loans and
         (ii) the aggregate amount of all Letter of Credit Outstandings exceeds
         the U.S. Revolving Loan Commitment Amount (as it may be reduced from
         time to time pursuant to this Agreement), the Company shall make a
         mandatory prepayment of Revolving Loans or Swing Line Loans (or both).

         Date occurring during any period set forth below, the Company shall

         Default is then continuing or except as otherwise agreed to by the
         Agents for disbursement at the request of the Company or the Restricted
         Subsidiary, as the case may be, or (ii) if all such Net Disposition
         Proceeds (together with Casualty Proceeds not applied as provided in
         clause (e) above) aggregating in excess of $500,000 have not yet been
         applied as described in the notice required above (or in accordance

                  (g) The Company shall, no later than five Business Days
         following the delivery by Holdings of its annual audited financial
         reports required pursuant to clause (c) of Section 7.1.1 (beginning
         with the financial reports delivered in respect of the 2000 Fiscal
         Year), deliver to the Agents a calculation of the Excess Cash Flow for
         the Fiscal Year last ended and make a mandatory prepayment of the Term

         that if the net proceeds of the Permanent Debt Financing are sufficient
         to pay in full the Subordinated Bridge Notes then Holdings or the

         Debt in excess of the amount required to pay in full the Subordinated
         Bridge Notes in an aggregate amount not to exceed the lesser of
         $10,000,000 or the then outstanding amount of Indebtedness evidenced by
         the Intermediate Holdings Asset Bridge Notes to redeem or prepay
         Intermediate Holdings Asset Bridge Notes and 100% of the remaining

         shall have delivered a certificate required to be delivered pursuant to
         clause (l) of Section 7.1.1 (or during a period that a Specified
         Default has occurred and is continuing on each Business Day), the
         applicable Foreign Borrower shall,

                           (A) if the U.S. Dollar Equivalent of the aggregate
                  outstanding principal amount of all Canadian Loans is equal to
                  or greater than 103% of the Canadian Revolving Loan Commitment
                  Amount, make a prepayment of its Canadian Loans in Canadian
                  Dollars (or cash collateralize Canadian BAs, if applicable) in
                  an amount equal to such excess over the Canadian Revolving
                  Loan Commitment Amount; and

                           (B) if the U.S. Dollar Equivalent of the aggregate
                  outstanding principal amount of all Australian Revolving Loans
                  is equal to or greater than 103% of the Australian Revolving
                  Loan Commitment Amount, make a prepayment of its Australian
                  Revolving Loans in Australian Dollars in an amount equal to
                  such excess over the Australian Revolving Loan Commitment
                  Amount.

For purposes of clause (i) above, the aggregate outstanding principal amount of
Foreign Currency Revolving Loans shall be calculated in accordance with the most
recently delivered certificate pursuant to clause (l) of Section 7.1.1;
provided, however, that if a Specified Default has occurred and is continuing,
the conversion rate of such Foreign Currency into U.S. Dollars shall be
determined by the Administrative Agent for each day.

                  (j) Immediately upon any acceleration of the Stated Maturity
         Date of any Loans pursuant to Section 8.2 or Section 8.3, the Borrowers
         shall repay all the Loans, unless, pursuant to Section 8.3, only a
         portion of all the Loans is so accelerated (in which case the portion
         so accelerated shall be so repaid).

Each prepayment of any Loans made pursuant to this Section shall be without
premium or penalty, except as may be required by Section 4.4.

         SECTION 3.1.2. Application. Amounts prepaid pursuant to Section 3.1.1
shall be applied as set forth in this Section.

                  (a) Subject to clause (b), each prepayment or repayment of the
         principal of the Loans shall be applied, to the extent of such
         prepayment or repayment, first, to the principal amount thereof being
         maintained as Base Rate Loans, and second, subject to the terms of
         Section 4.4, to the principal amount thereof being maintained as LIBO
         Rate Loans.

                  (b) Each prepayment of Term Loans made pursuant to clauses
         (e), (f), (g) and (h) of Section 3.1.1 shall be applied pro rata to a
         mandatory prepayment of the outstanding principal amount of all Term A
         Loans and Term B Loans (with the amount of such prepayment of the Term
         A Loans and the Term B Loans being applied to the remaining Term A Loan
         or Term B Loan, as the case may be, amortization payments, pro rata in
         accordance with the amount of each such remaining Term Loan
         amortization payments); provided, however, that in the case of any such
         prepayment of Term B Loans made pursuant to clause (e), (f), (g) and
         (h) of Section 3.1.1, any Lender that has Term B Loans may elect not to
         have such Loans prepaid by delivering a notice to the Agents at least
         one Business Day prior to the date that such prepayment is to be made
         in which notice such Lender shall decline to have such Loans prepaid
         with the amounts set forth above, in which case the amounts that would
         have been applied to a prepayment of such Lender's Term B Loans shall
         instead be applied to a prepayment of the principal amount (if any) of
         all outstanding Term A Loans until all outstanding Term A Loans have
         been prepaid in full, then applied to a prepayment of such Lender"s
         Term B Loans.

         Rate Loan, equal to the sum of the Alternate Base Rate (if such Loan is
         not a Canadian Loan) or Canadian Prime Rate (if such loan is a Canadian
         Loan) from time to time in effect plus the Applicable Margin; provided
         that all Swing Line Loans shall always accrue interest at the Alternate
         Base Rate plus the then effective Applicable Margin for such Revolving
         Loans; and

                  (b) on that portion maintained as a LIBO Rate Loan, during
         each Interest Period applicable thereto, equal to the sum of the LIBO

Period at the interest rate determined as applicable to such LIBO Rate Loan.

         SECTION 3.2.2. Post-Default Rates. Upon the occurrence and during the
continuance of an Event of Default, the Borrowers (other than the Canadian
Borrower) shall pay, but only to the extent permitted by law, interest (after as
well as before judgment) in an amount equal to (a) in the case of any principal
of LIBO Rate Loans or unpaid interest thereon, the rate that would otherwise be
applicable to such LIBO Rate Loans pursuant to Section 3.2.1 plus 2%, (b) in the
case of any principal of Base Rate Loans or unpaid interest thereon, the rate
that would otherwise be applicable to such Base Rate Loans pursuant to Section
3.2.1 plus 2% and (c) in the case of any accrued and unpaid commitment fees,
letter of credit fees or other monetary Obligations, the rate that would
otherwise be applicable to Revolving Loans that are maintained as Base Rate
Loans pursuant to Section 3.2.1 plus 2%.

         SECTION 3.2.3. Payment Dates. Interest accrued on each Loan shall be

                  (d) with respect to LIBO Rate Loans, on the last day of each
         applicable Interest Period (and, if such Interest Period shall exceed
         three months, on the date occurring on each three-month interval
         occurring after the first day of such Interest Period);

                  (e) with respect to any Base Rate Loans converted into LIBO
         Rate Loans on a day when interest would not otherwise have been payable
         pursuant to clause (c), on the date of such conversion; and

                  (f) on that portion of any Loans the Stated Maturity Date of

All such fees shall be non-refundable.

Margin, in each case on such Lender"s Percentage of the sum of the average daily
unused portion of the applicable Commitment Amount (other than the Canadian
Revolving Loan Commitment Amount and the Australian Revolving Loan Commitment
Amount) (net of Letter of Credit Outstandings, in the case of U.S. Revolving
Loan Commitment Amount). The making of Swing Line Loans shall not constitute
usage of the Revolving Loan Commitment with respect to the calculation of
commitment fees to be paid by the Company to the Lenders other than with respect
to the Swing Line Lender.

         (b) The Canadian Borrower agrees to pay directly to the account of each

inability to satisfy any condition of Article V) commencing on the Effective
Date and continuing through the Revolving Loan Commitment Termination Date, a
commitment fee in an amount equal to the Applicable Commitment Fee Margin, in
each case on such Lender"s Percentage of the sum of the average daily unused
portion of the Canadian Revolving Loan Commitment Amount.

         (c) The Australian Borrower agrees to pay directly to the account of
each Australian Lender, for the period (including any portion thereof when its
Australian Revolving Loan Commitment is suspended by reason of the Australian
Borrower"s inability to satisfy any condition of Article V) commencing on the
Effective Date and continuing through the Revolving Loan Commitment Termination
Date, a commitment fee in an amount equal to the Applicable

                                      -68-
<PAGE>   69

Commitment Fee Margin, in each case on such Lender's Percentage of the sum of
the average daily unused portion of the Australian Revolving Loan Commitment
Amount.

         (d) All commitment fees payable pursuant to this Section shall be
payable by the applicable Borrower in arrears on the Effective Date and
thereafter on each Quarterly Payment Date, commencing with the first Quarterly
Payment Date following the Effective Date, and on the Revolving Loan Commitment

Administrative Agent, for its own account, the fees in the amounts and on the
dates set forth in the Administrative Agent Fee Letter.

Administrative Agent, for the pro rata account of the applicable Issuer and each
U.S. Revolving Loan Lender, a Letter of Credit fee in an amount equal to the

Rate Loans, multiplied by the Stated Amount of each such Letter of Credit, such
fees being payable quarterly in arrears on each Quarterly Payment Date following
the date of issuance of each Letter of Credit and on the Revolving Loan
Commitment Termination Date. The Company further agrees to pay to the applicable
Issuer with respect to each issuance or extension of a Letter of Credit an
issuance fee in an amount equal to 1/4 of 1% per annum on the Stated Amount of
such Letter of Credit payable on each Quarterly Payment Date following the date
of such issuance or extension and on the Revolving Loan Commitment Termination
Date.

                                   ARTICLE IV
                     CERTAIN LIBO RATE AND OTHER PROVISIONS

         SECTION 4.1. LIBO Rate Lending Unlawful. If any Lender shall determine
(which determination shall, upon notice thereof to the Borrowers and the
Administrative Agent, be conclusive and binding on the Borrowers) that the
introduction of or any change in or in the interpretation of any law makes it
unlawful, or any Governmental Authority asserts that it is unlawful, for such
Lender to make or continue any Loan as, or to convert any Loan into, a LIBO Rate
Loan, the obligations of such Lender to make, continue or convert any such LIBO
Rate Loan shall, upon such determination, forthwith be suspended until such
Lender shall notify the Administrative Agent that the circumstances causing such
suspension no longer exist, and all outstanding LIBO Rate Loans payable to such
Lender shall automatically convert into Base Rate Loans or in the case of
Australian Revolving Loans shall bear interest as set forth in Section 4.2 at
the end of the then current Interest Periods with respect thereto or sooner, if
required by such law or assertion.

                                      -69-
<PAGE>   70

         SECTION 4.2. Deposits Unavailable; Circumstances making Canadian BAs
Unavailable. If the Administrative Agent shall have determined that

                  (a) deposits in the relevant Currency and amount and for the
         relevant Interest Period are not available to it in its relevant
         market; or

                  (b) by reason of circumstances affecting its relevant market,
         adequate means do not exist for ascertaining the interest rate
         applicable hereunder to LIBO Rate Loans in a particular Currency;

then, upon notice from the Administrative Agent to the Borrowers and the
Lenders, the obligations of all Lenders under Section 2.3 and Section 2.4 to
make or continue any Loans as, or to convert any Loans into, LIBO Rate Loans
shall forthwith be suspended and, in the case of U.S. Loans, such Loans shall
accrue interest at the Base Rate plus the Applicable Margin in respect of such
Loans and, in the case of Australian Revolving Loans, such Loans shall accrue
interest at each applicable Lender's cost of funds, as reasonably determined and
as notified by such Lender to the Administrative Agent and the applicable
Borrowers, plus the Applicable Margin in respect of such Loans, in each case
from the end of the then current Interest Period applicable thereto, until the
Administrative Agent shall notify the applicable Borrowers and the Lenders that
the circumstances causing such suspension no longer exist, and subsequent LIBO
Rate Loans in respect of such Currency shall be made at an interest rate equal
to, in the case of U.S. Loans, the Base Rate plus the Applicable Margin in
respect of such Loans, in the case of Canadian Loans, such Loans shall accrue
interest at the Canadian Prime Rate plus the Applicable Margin in respect of
such Loans and, in the case of Australian Revolving Loans, each applicable
Lender"s cost of funds, as reasonably determined and as notified by such Lender
to the Administrative Agent and the Borrowers, plus the Applicable Margin in
respect of such Loans.

         (c) If the Administrative Agent shall have determined that by reason of
circumstances affecting the Canadian money market, there is no market for
Canadian BAs, then the right of the Canadian Borrower to request the acceptance
of Canadian BAs and the acceptance thereof shall be suspended until the
Administrative Agent determines that the circumstances causing such suspension
no longer exist and the Administrative Agent so notifies the Canadian Borrower
and any Borrowing Request or Continuation/Conversion Notice requesting the
acceptance of Canadian BAs shall be canceled and the Loans requested therein
shall be made as, continued as or converted into Canadian Prime Rate Loans or,
in the case of a Credit Extension, if requested by the Canadian Borrower at
least one Business Day prior to the scheduled date of the Credit Extension, not
be made.

         SECTION 4.3. Increased LIBO Rate Loan Costs, etc. Increased LIBO
Rate Loan Costs, etc. The applicable Borrower agrees to reimburse each Lender
and Issuer for any increase in the cost to such Lender or Issuer of, or any
reduction in the amount of any sum receivable by such Secured Party in respect
of, such Secured Party's Commitments and the making of Credit Extensions
hereunder (including the making, continuing or maintaining (or of its obligation
to make or continue) any Loans as, or of converting (or of its obligation to
convert) any Loans into, LIBO Rate Loans) that arise in connection with any

                                      -70-
<PAGE>   71

change in, or the introduction, adoption, effectiveness, interpretation,
reinterpretation or phase-in after the date hereof of, any law or regulation,
directive, guideline, decision or request (whether or not having the force of
law) of any Governmental Authority, except for such changes with respect to
increased capital costs and Taxes which are governed by Sections 4.5 and 4.6,
respectively. Each affected Secured Party shall promptly notify the
Administrative Agent and the Borrowers in writing of the occurrence of any such
event, stating the reasons therefor and the additional amount required fully to
compensate such Secured Party for such increased cost or reduced amount. Such
additional amounts shall be payable by the applicable Borrower directly to such
Secured Party within five days of its receipt of such notice, and such notice
shall, in the absence of manifest error, be conclusive and binding on the
Borrowers.

         SECTION 4.4. Funding Losses. Funding Losses. In the event any
Lender shall incur any loss or expense (including any loss or expense incurred
by reason of the liquidation or reemployment of deposits or other funds acquired
by such Lender to make or continue any portion of the principal amount of any
Loan as, or to convert any portion of the principal amount of any Loan into, a
LIBO Rate Loan) as a result of

                  (a) any conversion or repayment or prepayment of the principal
         amount of any LIBO Rate Loan on a date other than the scheduled last
         day of the Interest Period applicable thereto, whether pursuant to
         Article III or otherwise;

                  (b) any Loans not being made as LIBO Rate Loans in accordance
         with the Borrowing Request therefor (other than as a result of the
         willful failure of such Lender to fund such requested LIBO Rate Loan);
         or

                  (c) any Loans not being continued as, or converted into, LIBO
         Rate Loans in accordance with the Continuation/Conversion Notice
         therefor;

then, upon the written notice of such Lender to the applicable Borrowers (with a
copy to the Administrative Agent), the applicable Borrower shall, within five
days of its receipt thereof, pay directly to such Lender such amount as will (in
the reasonable determination of such Lender) reimburse such Lender for such loss
or expense. Such written notice shall, in the absence of manifest error, be
conclusive and binding on the Borrowers.

         SECTION 4.5. Increased Capital Costs. Increased Capital Costs. If
any change in, or the introduction, adoption, effectiveness, interpretation,
reinterpretation or phase-in of, any law or regulation, directive, guideline,
decision or request (whether or not having the force of law) of any Governmental
Authority affects or would affect the amount of capital required or expected to
be maintained by any Secured Party or any Person controlling such Secured Party,
and such Secured Party determines (in good faith but in its sole and absolute
discretion) that the rate of return on its or such controlling Person's capital
as a consequence of the Commitments or the Credit Extensions made, or the
Letters of Credit participated in, by such Secured Party is reduced to a level
below that which such Secured Party or such controlling Person could have
achieved but for the occurrence of any such circumstance, then upon notice from
time to time by such Secured Party to

                                      -71-
<PAGE>   72

the Borrowers, the applicable Borrower shall within five days following receipt
of such notice pay directly to such Secured Party additional amounts sufficient
to compensate such Secured Party or such controlling Person for such reduction
in rate of return. A statement of such Secured Party as to any such additional
amount or amounts shall, in the absence of manifest error, be conclusive and
binding on the Borrowers. In determining such amount, such Secured Party may use
any method of averaging and attribution that it (in its sole and absolute
discretion) shall deem applicable.

         SECTION 4.6. Taxes. Each Borrower covenants and agrees as
follows with respect to Taxes.

                  (a) Any and all payments by such Borrower under each Loan
         Document shall be made without setoff, counterclaim or other defense,
         and free and clear of, and without deduction or withholding for or on
         account of, any Taxes. In the event that any Taxes are required by law
         to be deducted or withheld from any payment required to be made by a
         Borrower to or on behalf of any Secured Party under any Loan Document,
         then:

                           (i) subject to clause (f), if such Taxes are
                  Non-Excluded Taxes, the amount of such payment shall be
                  increased as may be necessary such that such payment is made,
                  after withholding or deduction for or on account of such
                  Taxes, in an amount that is not less than the amount provided
                  for in such Loan Document; and

                           (ii) such Borrower shall withhold the full amount of
                  such Taxes from such payment (as increased pursuant to clause
                  (a) (i)) and shall pay such amount to the Governmental
                  Authority imposing such Taxes in accordance with applicable
                  law.

                  (b) In addition, such Borrower shall pay any and all Other
         Taxes imposed to the relevant Governmental Authority imposing such
         Other Taxes in accordance with applicable law.

                  (c) As promptly as practicable after the payment of any Taxes
         or Other Taxes, and in any event within 45 days of any such payment
         being due, the applicable Borrower shall furnish to the Administrative
         Agent a copy of an official receipt (or a certified copy thereof)
         evidencing the payment of such Taxes or Other Taxes. The Administrative
         Agent shall make copies thereof available to any Lender upon request
         therefor.

                  (d) Subject to clause (f), the Company shall indemnify each
         Secured Party for any Non-Excluded Taxes and Other Taxes levied,
         imposed or assessed on (and whether or not paid directly by) such
         Secured Party (whether or not such Non-Excluded Taxes or Other Taxes
         are correctly or legally asserted by the relevant Governmental
         Authority). Promptly upon having knowledge that any such Non-Excluded
         Taxes or Other Taxes have been levied, imposed or assessed, and
         promptly upon notice thereof by any Secured Party, the Company shall
         pay such Non-Excluded Taxes or Other Taxes directly to the relevant
         Governmental Authority (provided, however, that no Secured Party shall
         be under any obligation to provide any such notice to the Company). In
         addition, the Company shall

                                      -72-
<PAGE>   73

         indemnify each Secured Party for any incremental Taxes that may become
         payable by such Secured Party as a result of any failure of the Company
         to pay any Taxes when due to the appropriate Governmental Authority or
         to deliver to the Administrative Agent, pursuant to clause (c),
         documentation evidencing the payment of Taxes or Other Taxes. With
         respect to indemnification for Non-Excluded Taxes and Other Taxes
         actually paid by any Secured Party or the indemnification provided in
         the immediately preceding sentence, such indemnification shall be made
         within 30 days after the date such Secured Party makes written demand
         therefor. The Company acknowledges that any payment made to any Secured
         Party or to any Governmental Authority in respect of the
         indemnification obligations of the Company provided in this clause
         shall constitute a payment in respect of which the provisions of clause
         (a) and this clause shall apply.

                  (e) Each Non-Domestic Lender, on or prior to the date on which
         such Non-Domestic Lender becomes a Lender (other than an Australian
         Lender or a Canadian Lender) hereunder (and from time to time
         thereafter upon the request of the Borrower or the Administrative
         Agent, but only for so long as such non-Domestic Lender is legally
         entitled to do so), shall deliver to the Company and the Administrative
         Agent either

                           (i) (x) two duly completed copies of either (A)
                  Internal Revenue Service Form W-8BEN (with respect to treaty
                  benefits only) or (B) Internal Revenue Service Form W-8ECI, or
                  in either case an applicable successor form, and (y) a duly
                  completed copy of Internal Revenue Service Form W-8 or W-9 or
                  applicable successor form; or

                           (ii) in the case of a Non-Domestic Lender that is not
                  legally entitled to deliver either form listed in clause
                  (e)(i)(x) for the purposes specified therein, (x) a
                  certificate of a duly authorized officer of such Non-Domestic
                  Lender to the effect that such Non-Domestic Lender is not (A)
                  a "bank" within the meaning of Section 881(c)(3)(A) of the
                  Code, (B) a "10 percent shareholder" of the Company within the
                  meaning of Section 881(c)(3)(B) of the Code, or (C) a
                  controlled foreign corporation receiving interest from a
                  related person within the meaning of Section 881(c)(3)(C) of
                  the Code (such certificate, an "Exemption Certificate") and
                  (y) two duly completed copies of Internal Revenue Service Form
                  W-8BEN (with respect to Foreign status) or applicable
                  successor form.

                  (f) No Borrower shall be obligated to gross up any payments to
         any Lender pursuant to clause (a)(i), or to indemnify any Lender
         pursuant to clause (d), in respect of United States federal withholding
         taxes to the extent imposed as a result of (i) the failure of such
         Lender to deliver to the Company the form or forms and/or an Exemption
         Certificate, as applicable to such Lender, pursuant to clause (e), (ii)
         such form or forms and/or Exemption Certificate not establishing a
         complete exemption from U.S. federal withholding tax or the information
         or certifications made therein by the Lender being untrue or inaccurate
         on the date delivered in any material respect, or (iii) the Lender
         designating a successor lending office at which it maintains its Loans
         which has the effect of causing

                                      -73-
<PAGE>   74

         such Lender to become obligated for tax payments in excess of those in
         effect immediately prior to such designation; provided, however, that
         the Borrowers shall be obligated to gross up any payments to any such
         Lender pursuant to clause (a)(i), and to indemnify any such Lender
         pursuant to clause (d), in respect of United States federal withholding
         taxes if (i) any such failure to deliver a form or forms or an
         Exemption Certificate or the failure of such form or forms or Exemption
         Certificate to establish a complete exemption from U.S. federal
         withholding tax or inaccuracy or untruth contained therein resulted
         from a change in any applicable statute, treaty, regulation or other
         applicable law or any interpretation of any of the foregoing occurring
         after the date hereof, which change rendered such Lender no longer
         legally entitled to deliver such form or forms or Exemption Certificate
         or otherwise ineligible for a complete exemption from U.S. federal
         withholding tax, or rendered the information or certifications made in
         such form or forms or Exemption Certificate untrue or inaccurate in a
         material respect, (ii) the redesignation of the Lender's lending office
         was made at the request of the Company or (iii) the obligation to gross
         up payments to any such Lender pursuant to clause (a)(i) or to
         indemnify any such Lender pursuant to clause (d) is with respect to an
         Assignee Lender that becomes an Assignee Lender as a result of an
         assignment made at the request of the Company.

         SECTION 4.7. Payments, Computations, etc. Unless otherwise expressly
provided in a Loan Document, all payments by the Borrowers pursuant to each Loan
Document shall be made by the Borrowers to the Administrative Agent for the pro
rata account of the Secured Parties entitled to receive such payment; provided,
that, payments of principal and interest on the Canadian Loans and the
Australian Revolving Loans shall be made directly to the Lenders entitled
thereto. All payments shall be made without setoff, deduction or counterclaim
not later than 11:00 a.m. on the date due in same day or immediately available
funds to such account as the Administrative Agent, or the Canadian Lenders or
Australian Lenders as the case may be, shall specify from time to time by notice
to the Borrowers. Funds received after that time shall be deemed to have been
received by the Administrative Agent, or such Lenders as the case may be, on the
next succeeding Business Day. The Administrative Agent shall promptly remit in
same day funds to each Secured Party its share, if any, of such payments
received by the Administrative Agent for the account of such Secured Party. All
interest (including interest on LIBO Rate Loans) and fees shall be computed on
the basis of the actual number of days (including the first day but excluding
the last day) occurring during the period for which such interest or fee is
payable over a year comprised of 360 days (or, in the case of interest on a Base
Rate Loan (calculated at other than the Federal Funds Rate), 365 days or, if
appropriate, 366 days). Payments due on other than a Business Day shall (except
as otherwise required by clause (c) of the definition of the term "Interest
Period") be made on the next succeeding Business Day and such extension of time
shall be included in computing interest and fees in connection with that
payment.

         SECTION 4.8. Sharing of Payments. If any Secured Party shall obtain any
payment or other recovery (whether voluntary, involuntary, by application of
setoff or otherwise) on account of any Credit Extension or Reimbursement
Obligation (other than pursuant to the terms of Sections 4.3, 4.4, 4.5 or 4.6)
in excess of its pro rata share of payments obtained by all Secured Parties,
such Secured Party shall purchase from the other Secured Parties such
participations in Credit

                                      -74-
<PAGE>   75

Extensions made by them as shall be necessary to cause such purchasing Secured
Party to share the excess payment or other recovery ratably (to the extent such
other Secured Parties were entitled to receive a portion of such payment or
recovery) with each of them; provided, however, that if all or any portion of
the excess payment or other recovery is thereafter recovered from such
purchasing Secured Party, the purchase shall be rescinded and each Secured Party
which has sold a participation to the purchasing Secured Party shall repay to
the purchasing Secured Party the purchase price to the ratable extent of such
recovery together with an amount equal to such selling Secured Party's ratable
share (according to the proportion of (a) the amount of such selling Secured
Party's required repayment to the purchasing Secured Party to (b) total amount
so recovered from the purchasing Secured Party) of any interest or other amount
paid or payable by the purchasing Secured Party in respect of the total amount
so recovered. Each Borrower agrees that any Secured Party purchasing a
participation from another Secured Party pursuant to this Section may, to the
fullest extent permitted by law, exercise all its rights of payment (including
pursuant to Section 4.9) with respect to such participation as fully as if such
Secured Party were the direct creditor of such Borrower in the amount of such
participation. If under any applicable bankruptcy, insolvency or other similar
law any Secured Party receives a secured claim in lieu of a setoff to which this
Section applies, such Secured Party shall, to the extent practicable, exercise
its rights in respect of such secured claim in a manner consistent with the
rights of the Secured Parties entitled under this Section to share in the
benefits of any recovery on such secured claim.

         SECTION 4.9. Setoff. Each Secured Party shall, upon the occurrence and
during the continuance of any Default described in clauses (b) through (d) of
Section 8.1.9 or, with the consent of the Required Lenders, upon the occurrence
and during the continuance of any other Event of Default, have the right to
appropriate and apply to the payment of the Obligations owing to it (whether or
not then due), and (as security for such Obligations) Holdings and each Borrower
hereby grants to each Secured Party a continuing security interest in, any and
all balances, credits, deposits, accounts or moneys of Holdings or such Borrower
then or thereafter maintained with such Secured Party; provided, however, that
any such appropriation and application shall be subject to the provisions of
Section 4.8. Each Secured Party agrees promptly to notify Holdings and the
Company and the Administrative Agent after any such setoff and application made
by such Secured Party; provided, however, that the failure to give such notice
shall not affect the validity of such setoff and application. The rights of each
Secured Party under this Section are in addition to other rights and remedies
(including other rights of setoff under applicable law or otherwise) which such
Secured Party may have.

         SECTION 4.10. Replacement of Lenders. Each Lender hereby severally
agrees as set forth in this Section. If any Lender (a "Subject Lender") (i)
makes demand upon a Borrower for (or if such Borrower is otherwise required to
pay) amounts pursuant to Section 4.3, 4.5 or 4.6 or (ii) gives notice pursuant
to Section 4.1 requiring a conversion of such Subject Lender's LIBO Rate Loans
to Base Rate Loans or any change in the basis upon which interest is to accrue
in respect of such Subject Lender's LIBO Rate Loans or suspending such Lender's
obligation to make Loans as, or to convert Loans into, LIBO Rate Loans, the
Company may, within 180 days of receipt by such Borrower of such demand or
notice (or the occurrence of such other event causing such Borrower to be
required to pay such compensation) as the case may be, give notice (a

                                      -75-
<PAGE>   76

"Replacement Notice") in writing to the Agents and such Subject Lender of its
intention to replace such Subject Lender with a financial institution (a
"Replacement Lender") designated in such Replacement Notice. If the Agents
shall, in the exercise of their reasonable discretion and within 30 days of
their receipt of such Replacement Notice, notify the Company and such Subject
Lender in writing that the designated financial institution is satisfactory to
the Agents (such consent not being required where the Replacement Lender is
already a Lender), then such Subject Lender shall, subject to the payment of any
amounts due pursuant to Section 4.4, assign, in accordance with Section 11.11.1,
all of its Commitments, Loans and other rights and obligations under this
Agreement and all other Loan Documents (including Reimbursement Obligations) to
such designated financial institution; provided, however, that (i) such
assignment shall be without recourse, representation or warranty and shall be on
terms and conditions reasonably satisfactory to such Subject Lender and such
designated financial institution and (ii) the purchase price paid by such
designated financial institution shall be in the amount of such Subject Lender's
Loans and its Percentage in respect of any Revolving Loan Commitment under which
there are outstanding Reimbursement Obligations of such Reimbursement
Obligation, together with all accrued and unpaid interest and fees in respect
thereof, plus all other amounts (including the amounts demanded and unreimbursed
under Sections 4.3, 4.5 and 4.6), owing to such Subject Lender hereunder. Upon
the effective date of an assignment described above, the designated financial
institution or Replacement Lender shall become a "Lender" for all purposes under
this Agreement and the other Loan Documents.

                  (h) there are no polychlorinated biphenyls or friable asbestos
         present at any property now or previously owned, leased or operated
         upon (including right of way easements) by Holdings or any Subsidiary
         that, singly or in the aggregate, have, or could reasonably be expected
         to have, a Material Adverse Effect; and

                  (i) no conditions exist at, on or under any properties now or
         previously owned, leased or operated upon (including right of way
         easements) by Holdings or any of its Subsidiaries which, with the
         passage of time, or the giving of notice or both, would singly or in
         the aggregate give rise to liability under any Environmental Law which
         could reasonably be expected to have a Material Adverse Effect.

         SECTION 6.13. Accuracy of Information. None of the factual information
heretofore or contemporaneously furnished in writing to any Secured Party by or
on behalf of any Obligor in connection with any Loan Document or any transaction
contemplated hereby (including the

                                      -89-
<PAGE>   90
Transaction) contains any untrue statement of a material fact, or omits to state
any material fact necessary to make any information not misleading in light of
the circumstances under which made, and no other factual information hereafter
furnished in connection with any Loan Document by or on behalf of any Obligor to
any Secured Party will contain any untrue statement of a material fact or will
omit to state any material fact necessary to make any information not misleading
in light of the circumstances under which made on the date as of which such
information is dated or certified.

         SECTION 6.14. Regulations U and X. No Obligor is engaged in the
business of extending credit for the purpose of purchasing or carrying margin
stock, and no proceeds of any Credit Extensions will be used to purchase or
carry margin stock or otherwise for a purpose which violates, or would be
inconsistent with, F.R.S. Board Regulation U or Regulation X. Terms for which
meanings are provided in F.R.S. Board Regulation U or Regulation X or any
regulations substituted therefor, as from time to time in effect, are used in
this Section with such meanings.

         SECTION 6.15. Year 2000. Except as disclosed on Item 6.15 of the
Disclosure Schedule, each Obligor has reviewed the areas within its business and
operations which could be adversely affected by, and has developed or is
developing a program to address, the "Year 2000 Problem" (that is, the risk that
computer applications used by such Obligor may be unable to recognize and
properly perform date-sensitive functions involving certain dates prior to and
any date on or after December 31, 1999). Based on such review and program, the
Year 2000 Problem could not reasonably be expected to have a Material Adverse
Effect.

         SECTION 6.16. Issuance of Subordinated Debt; Status of Obligations as
Senior Indebtedness, etc. The Company has the power and authority to incur the
Subordinated Debt evidenced by the Subordinated Bridge Notes as provided for
under the Subordinated Debt Documents applicable thereto and has duly
authorized, executed and delivered the Subordinated Debt Documents applicable to
such Subordinated Debt. The Company has issued, pursuant to due authorization,
the Subordinated Debt evidenced by the Subordinated Bridge Notes under the
applicable Subordinated Debt Documents, and such Subordinated Debt Documents
constitute the legal, valid and binding obligations of the Company enforceable
against it in accordance with its terms (except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization or similar laws
affecting creditors' rights generally and by principles of equity). The
subordination provisions of the Subordinated Bridge Notes contained in the
applicable Subordinated Debt Documents are enforceable against the holders of
such Subordinated Debt by the holder of any "Senior Indebtedness" or similar
term referring to the Obligations (as defined in the Subordinated Debt
Documents). All Obligations, including those to pay principal of and interest
(including post-petition interest, whether or not allowed as a claim under
bankruptcy or similar laws) on the Loans and Reimbursement Obligations, and fees
and expenses in connection therewith, constitute "Senior Indebtedness" (or
similar term) relating to the Obligations (as defined in the Subordinated Debt
Documents) and all such Obligations are entitled to the benefits of the
subordination created by the Subordinated Debt Documents. The Company
acknowledges that each Agent, each Lender and each Issuer is entering into this
Agreement and is extending its Commitments in reliance upon the subordination
provisions of the Subordinated Debt Documents.

         SECTION 6.17. Solvency. The Transaction (including, among other things,
the incurrence of the initial Credit Extension hereunder and the execution and
delivery by the Guarantors of the Guarantees) will not involve or result in any
fraudulent transfer or fraudulent conveyance under the provisions of Section 548
of the Bankruptcy Code (11 U.S.C. Section 101 et seq., as from time to time
hereafter amended, and any successor or similar statute) or any applicable state
law respecting fraudulent transfers or fraudulent conveyances. On the Closing
Date, after giving effect to the Transaction (including, among other things, the
incurrence of the initial Credit Extension hereunder and the execution and
delivery by the Guarantors of the Guarantees), Holdings and its Subsidiaries,
Intermediate Holdings and its Subsidiaries and the Company and the Restricted
Subsidiaries, in each case taken as a whole, are Solvent.

<PAGE>   97

properties acquired subsequent to the Effective Date. Such security interests
and Liens will be created under the Loan Documents in form and substance
satisfactory to the Agents, and each of Holdings and the Company shall deliver
or cause to be delivered to the Lenders all such instruments and documents
(including legal opinions, title insurance policies and lien searches) as the
Agents shall reasonably request to evidence compliance with this Section.

         SECTION 7.1.9. Rate Protection Agreements. Within 90 days following the
Closing Date, the Company will enter into interest rate swap, cap, collar or
similar arrangements designed to protect the Company against fluctuations in
interest rates to the extent necessary to provide that at least 50% of the
aggregate principal amount then outstanding of Term Loans and Indebtedness
permitted under clause (g) of Section 7.2.2 is subject to a fixed interest rate
(after giving effect to each such arrangement) for a minimum period of two years
from the date of such determination (but not beyond the Stated Maturity Date of
the Term B Loans), with the terms and conditions of such arrangement being
reasonably satisfactory to the Agents.

         SECTION 7.1.10. Use of Proceeds of Holdings Disposition of Capital
Stock or Assets. Immediately upon the Disposition of any of its Capital Stock by

amount equal to the remaining balance of such Net Equity Proceeds. Immediately
upon the receipt of the net proceeds of any Disposition of Kalyn/Siebert,
Intermediate Holdings shall immediately make an equity contribution of such net
proceeds to the common equity of the Company to the extent such net proceeds are
not used to prepay or redeem Intermediate Holdings Asset Bridge Notes and use
the proceeds of such a capital contribution to make a prepayment of Term Loans
pursuant to clause (a) of Section 3.1.1.

         SECTION 7.1.11. RailAmerica Limited Pty Limited Constitution. The
Company undertakes to procure the delivery to the Administrative Agent of a
certified copy of the constitution of RAPL on the first day following the date
of the Australian Equitable Mortgage of Shares No.2.

         SECTION 7.2. Negative Covenants. Each of Holdings, Intermediate
Holdings and each Borrower covenants and agrees with each Lender, each Issuer
and each Agent that until the Termination Date has occurred, Holdings,
Intermediate Holdings and each Borrower will, and will cause the Restricted
Subsidiaries to, perform or cause to be performed the obligations set forth

Obligations; or Holdings, the Company or any of their respective Restricted
Subsidiaries shall, directly or indirectly, disavow or contest in any manner (i)
the effectiveness, validity or enforceability of any of the Subordination
Provisions, (ii) that the Subordination Provisions exist for the benefit of the
Agents, the Lenders and the Issuers or (iii) that all payments of principal of
or premium and interest on the Subordinated Debt, or realized from the
liquidation of any property of any Obligor, shall be subject to any of such
Subordination Provisions.

         SECTION 8.1.12. Failure to Refinance or Extend the Subordinated Bridge
Notes. The Company shall have failed to consummate a Permanent Financing of
Indebtedness in respect of the Subordinated Bridge Notes prior to the Maturity
Date (as defined in the Securities Purchase Agreement, the "Bridge Note Maturity
Date") and the Administrative Agent shall not have received, prior to the Bridge
Note Maturity Date, evidence satisfactory to it that the maturity of the
Subordinated Bridge Notes will, effective on the Bridge Note Maturity Date, be
extended to the date that is at least six months following the Stated Maturity
Date for the Term B Loans.

         SECTION 8.2. Action if Bankruptcy. If any Event of Default described in
clauses (a) through (d) of Section 8.1.9 with respect to Holdings or any
Borrower shall occur, the Commitments (if not theretofore terminated) shall
automatically terminate and the outstanding principal amount of all outstanding
Loans and all other Obligations (including Reimbursement Obligations) shall
automatically be and become immediately due and payable, without notice or
demand to any Person and each Obligor shall automatically and immediately be
obligated to Cash Collateralize all Letter of Credit Outstandings.

         SECTION 8.3. Action if Other Event of Default. If any Event of Default
(other than any Event of Default described in clauses (a) through (d) of Section
8.1.9 with respect to Holdings or any Borrower) shall occur for any reason,
whether voluntary or involuntary, and be continuing, the Administrative Agent,
upon the direction of the Required Lenders, shall by notice to the Borrowers
declare all or any portion of the outstanding principal amount of the Loans and
other Obligations (including Reimbursement Obligations) to be due and payable
and/or the Commitments (if not theretofore terminated) to be terminated,
whereupon the full unpaid amount of such Loans and other Obligations which shall
be so declared due and

                                     -112-
<PAGE>   113

payable shall be and become immediately due and payable, without further notice,
demand or presentment, and/or, as the case may be, the Commitments shall
terminate and the Company shall automatically and immediately be obligated to
Cash Collateralize all Letter of Credit Outstandings.

                                   ARTICLE IX
                            THE ADMINISTRATIVE AGENT

         SECTION 9.1. Actions. Each Lender hereby appoints DLJ as its
Syndication Agent and The Bank of Nova Scotia as Administrative Agent under and
for purposes of each Loan Document. Each Lender authorizes each Agent to act on
behalf of such Lender under each Loan Document and, in the absence of other
written instructions from the Required Lenders received from time to time by the
Agents (with respect to which each Agent agrees that it will comply, except as
otherwise provided in this Section or as otherwise advised by counsel in order
to avoid contravention of applicable law), to exercise such powers hereunder and
thereunder as are specifically delegated to or required of such Agent by the
terms hereof and thereof, together with such powers as may be reasonably
incidental thereto. Each Lender hereby indemnifies (which indemnity shall
survive any termination of this Agreement) each Agent, pro rata according to
such Lender's proportionate Total Exposure Amount, from and against any and all
liabilities, obligations, losses, damages, claims, costs or expenses of any kind
or nature whatsoever which may at any time be imposed on, incurred by, or
asserted against, such Agent in any way relating to or arising out of any Loan
Document, including reasonable attorneys' fees, and as to which such Agent is
not reimbursed by Holdings or the Company; provided, however, that no Lender
shall be liable for the payment of any portion of such liabilities, obligations,
losses, damages, claims, costs or expenses which are determined by a court of
competent jurisdiction in a final proceeding to have resulted from such Agent's
gross negligence or wilful misconduct. Neither Agent shall be required to take
any action under any Loan Document, or to prosecute or defend any suit in
respect of any Loan Document, unless it is indemnified hereunder to its
satisfaction. If any indemnity in favor of either Agent shall be or become, in
such Agent's determination, inadequate, such Agent may call for additional
indemnification from the Lenders and cease to do the acts indemnified against
hereunder until such additional indemnity is given.

         SECTION 9.2. Funding Reliance, etc. Unless the Administrative Agent
shall have been notified in writing by any Lender by 3:00 p.m. on the Business
Day prior to a Borrowing that such Lender will not make available the amount
which would constitute its Percentage of such Borrowing on the date specified
therefor, the Administrative Agent may assume that such Lender has made such
amount available to the Administrative Agent and, in reliance upon such
assumption, make available to the applicable Borrower a corresponding amount. If
and to the extent that such Lender shall not have made such amount available to
the Administrative Agent, such Lender and Holdings and the Company severally
agree to repay the Administrative Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date the
Administrative Agent made such amount available to the applicable Borrower to
the date such amount is repaid to the Administrative Agent, at the interest rate
applicable at the time to Loans comprising such Borrowing (in the case of a
Borrower) and (in the case of a Lender), at the

                                     -113-
<PAGE>   114

Federal Funds Rate for the first two Business Days after which such amount has
not been repaid, and thereafter at the interest rate applicable to Loans
comprising such Borrowing.

         SECTION 9.3. Exculpation. Neither Agent nor any of its directors,
officers, employees or agents shall be liable to any Lender for any action taken
or omitted to be taken by it under any Loan Document, or in connection herewith
or therewith, except for its own wilful misconduct or gross negligence, nor
responsible for any recitals or warranties herein or therein, nor for the
effectiveness, enforceability, validity or due execution of any Loan Document,
nor for the creation, perfection or priority of any Liens purported to be
created by any of the Loan Documents, or the validity, genuineness,
enforceability, existence, value or sufficiency of any collateral security, nor
to make any inquiry respecting the performance by any Obligor of its
Obligations. Any such inquiry which may be made by either Agent shall not
obligate it to make any further inquiry or to take any action. The
Administrative Agent shall be entitled to rely upon advice of counsel concerning
legal matters and upon any notice, consent, certificate, statement or writing
which the Administrative Agent believes to be genuine and to have been presented
by a proper Person.

         SECTION 9.4. Successor. The Syndication Agent may resign as such upon
one Business Day's notice to the Borrowers and the Administrative Agent. The
Administrative Agent may resign as such at any time upon at least 30 days' prior
notice to Holdings and the Borrowers and all Lenders. If the Administrative
Agent at any time shall resign, the Required Lenders may appoint another Lender
as a successor Administrative Agent which shall thereupon become the
Administrative Agent hereunder. If no successor Administrative Agent shall have
been so appointed by the Required Lenders, and shall have accepted such
appointment, within 30 days after the retiring Administrative Agent's giving
notice of resignation, then the retiring Administrative Agent may, on behalf of
the Lenders, appoint a successor Administrative Agent, which shall be one of the
Lenders or a commercial banking institution organized under the laws of the U.S.
(or any state thereof) or a U.S. branch or agency of a commercial banking
institution, and having a combined capital and surplus of at least $250,000,000;
provided, however that if, such retiring Administrative Agent is unable to find
a commercial banking institution which is willing to accept such appointment and
which meets the qualifications set forth in above, the retiring Administrative
Agent's resignation shall nevertheless thereupon become effective and the
Lenders shall assume and perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Lenders appoint a successor
as provided for above. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor Administrative Agent, such successor
Administrative Agent shall be entitled to receive from the retiring
Administrative Agent such documents of transfer and assignment as such successor
Administrative Agent may reasonably request, and shall thereupon succeed to and
become vested with all rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations under the Loan Documents. After any retiring
Administrative Agent's resignation hereunder as the Administrative Agent, the
provisions of this Article shall inure to its benefit as to any actions taken or
omitted to be taken by it while it was the Administrative Agent under the Loan
Documents, and Section 11.3 and Section 11.4 shall continue to inure to its
benefit. If the Syndication Agent shall resign, then all actions required to be
taken by

                                     -114-
<PAGE>   115

or consented to by the Agents shall only be required to be taken or consented
to, as the case may be, by the Administrative Agent.

         SECTION 9.5. Credit Extensions by each Agent and Issuer. Each Agent and
each Issuer shall have the same rights and powers with respect to (x)(i) in the
case of an Agent, the Credit Extensions made by it or any of its Affiliates and
(ii) in the case of an Issuer, the Loans made by it or any of its Affiliates,
and (y) the Notes held by it or any of its Affiliates as any other Lender and
may exercise the same as if it were not an Agent or Issuer. Each Agent, each
Issuer and each of their respective Affiliates may accept deposits from, lend
money to, and generally engage in any kind of business with Holdings, the
Company or any Subsidiary or Affiliate of Holdings as if such Agent or Issuer
were not an Agent or Issuer hereunder.

         SECTION 9.6. Credit Decisions. Each Lender acknowledges that it has,
independently of each Agent and each other Lender, and based on such Lender's
review of the financial information of Holdings and the Company, the Loan
Documents (the terms and provisions of which being satisfactory to such Lender)
and such other documents, information and investigations as such Lender has
deemed appropriate, made its own credit decision to extend its Commitments. Each
Lender also acknowledges that it will, independently of each Agent and each
other Lender, and based on such other documents, information and investigations
as it shall deem appropriate at any time, continue to make its own credit
decisions as to exercising or not exercising from time to time any rights and
privileges available to it under the Loan Documents.

         SECTION 9.7. Copies, etc. The Administrative Agent shall give prompt
notice to each Lender of each notice or request required or permitted to be
given to the Administrative Agent by Holdings or any Borrower pursuant to the
terms of the Loan Documents (unless concurrently delivered to the Lenders by
Holdings or any Borrower). The Administrative Agent will distribute to each
Lender each document or instrument received for its account and copies of all
other communications received by the Administrative Agent from the Company for
distribution to the Lenders by the Administrative Agent in accordance with the
terms of the Loan Documents.

         SECTION 9.8. Reliance by Agents. Each Agent shall be entitled to rely
upon any certification, notice or other communication (including any thereof by
telephone, telecopy, telegram or cable) believed by it to be genuine and correct
and to have been signed or sent by or on behalf of the proper Person, and upon
advice and statements of legal counsel, independent accountants and other
experts selected by such Agent. As to any matters not expressly provided for by
the Loan Documents, each Agent shall in all cases be fully protected in acting,
or in refraining from acting, hereunder or thereunder in accordance with
instructions given by the Required Lenders or all of the Lenders as is required
in such circumstance, and such instructions of such Lenders and any action taken
or failure to act pursuant thereto shall be binding on all Secured Parties. For
purposes of applying amounts in accordance with this Section, each Agent shall
be entitled to rely upon any Secured Party that has entered into a Rate
Protection Agreement with any Obligor for a determination (which such Secured
Party agrees to provide or cause to be provided upon request of each Agent) of
the outstanding Obligations owed to such Secured Party under any Rate Protection
Agreement. Unless it has actual knowledge evidenced by way of

                                     -115-
<PAGE>   116

written notice from any such Secured Party and the Company to the contrary, each
Agent, in acting in such capacity under the Loan Documents, shall be entitled to
assume that no Rate Protection Agreements or Obligations in respect thereof are
in existence or outstanding between any Secured Party and any Obligor.

         SECTION 9.9. Defaults. Neither Agent shall be deemed to have knowledge
or notice of the occurrence of a Default unless such Agent has received a
written notice from a Lender or Holdings or any Borrower specifying such Default
and stating that such notice is a "Notice of Default". In the event that either
Agent receives such a notice of the occurrence of a Default, such Agent shall
give prompt notice thereof to the Lenders. Each Agent shall (subject to Section
11.1) take such action with respect to such Default as shall be directed by the
Required Lenders; provided, that unless and until such Agent shall have received
such directions, such Agent may (but shall not be obligated to) take such
action, or refrain from taking such action, with respect to such Default as it
shall deem advisable in the best interest of the Lenders except to the extent
that this Agreement expressly requires that such action be taken, or not be
taken, only with the consent or upon the authorization of the Required Lenders
or all Lenders, as applicable.

         SECTION 9.10. Documentation Agent. The Lender identified on the
signature pages of this Agreement as the "Documentation Agent" shall not have
any right, power, obligation, liability, responsibility or duty under this
Agreement (or any other Loan Document) other than those applicable to all
Lenders as such. Without limiting the foregoing, the Lender so identified as the
"Documentation Agent" shall not have or be deemed to have any fiduciary
relationship with any other Lender. Each Lender acknowledges that it has not
relied, and will not rely, on the Lender so identified as the "Documentation
Agent" in deciding to enter into this Agreement and each other Loan Document to
which it is a party or in taking or not taking action hereunder or thereunder.

         SECTION 9.11. Security Trust Deed. In order for the Lenders to become
beneficiaries under the Australian Security Trust Deed, the Administrative Agent
is hereby authorized and instructed to execute as agent on behalf each Lender an
Australian Accession Deed. Each Lender authorizes the Administrative Agent to
act as its representative for the purposes of the Australian Security Trust Deed
in connection with any communication or other dealings with the Australian
Security Trustee, and the Australian Security Trustee shall not be required to
accept any communication from any other party other than the Administrative
Agent with respect to any request, instruction, direction, approval, consent,
agreement or other instruction of the Lenders (as beneficiaries) under the
Australian Security Trust Deed.

                                    ARTICLE X

                   HOLDINGS AND INTERMEDIATE HOLDINGS GUARANTY

         SECTION 10.1. Guaranty. Each of Holdings and Intermediate Holdings
hereby, jointly and severally, absolutely, unconditionally and irrevocably

                                     -116-
<PAGE>   117

                  (a) guarantees the full and punctual payment when due, whether
         at stated maturity, by required prepayment, declaration, acceleration,
         demand or otherwise, of all Obligations of each Borrower and each other
         Obligor now or hereafter existing under this Agreement and each other
         Loan Document to which such Borrower and each other Obligor is or may
         become a party, whether for principal, interest, fees, expenses or
         otherwise (including all such amounts which would become due but for
         the operation of the automatic stay under Section 362(a) of the United
         States Bankruptcy Code, 11 U.S.C. Section 362(a), and the operation of
         Sections 502(b) and 506(b) of the United States Bankruptcy Code,
         11 U.S.C. Section 502(b) and Section 506(b)), and

                  (b) indemnifies and holds harmless each Lender for any and all
         costs and expenses (including reasonable attorney's fees and expenses)
         incurred by such Lender or such holder, as the case may be, in
         enforcing any rights under this Article X;

This Article X constitutes a guaranty of payment when due and not of collection,
and Holdings and Intermediate Holdings specifically agree that it shall not be
necessary or required that any Lender exercise any right, assert any claim or
demand or enforce any remedy whatsoever against any Borrower or any other
Obligor (or any other Person) before or as a condition to the obligations of
Holdings and Intermediate Holdings hereunder.

         SECTION 10.2. Acceleration of Obligations Hereunder. Holdings and
Intermediate Holdings agree that, in the event of the dissolution or insolvency
of any Borrower or any other Obligor, or the inability or failure of any
Borrower or any other Obligor to pay its debts as they become due, or an
assignment by any Borrower or any other Obligor for the benefit of creditors, or
the commencement of any case or proceeding in respect of any Borrower or any
other Obligor under any bankruptcy, insolvency or similar laws, and if such
event shall occur at a time when any of the Obligations of any Borrower or any
other Obligor may not then be due and payable, Holdings and Intermediate
Holdings agree that they will pay to the Lenders forthwith the full amount which
would be payable hereunder by such Borrower or such other Obligor if all such
Obligations were then due and payable.

         SECTION 10.3. Obligations Hereunder Absolute, etc. The obligations of
Holdings and Intermediate Holdings under this Article X shall in all respects be
a continuing, absolute, unconditional and irrevocable guaranty of payment, and
shall remain in full force and effect until all Obligations of each Borrower and
each other Obligor have been paid in full and all Commitments shall have
terminated. Holdings and Intermediate Holdings guarantee that the Obligations of
each Borrower and each other Obligor will be paid strictly in accordance with
the terms of this Agreement and each other Loan Document under which they arise,
regardless of any law, regulation or order now or hereafter in effect in any
jurisdiction affecting any of such terms or the rights of any Lender or any
holder of any Note with respect thereto. The liability of Holdings and
Intermediate Holdings under this Article X shall be absolute, unconditional and
irrevocable irrespective of:

                                     -117-
<PAGE>   118

                  (a) any lack of validity, legality or enforceability of other
         provisions of this Agreement or any other Loan Document;

                  (b) the failure of any Lender

                           (i)  to assert any claim or demand or to enforce any
                  right or remedy against any Borrower, any other Obligor or any
                  other Person (including any other guarantor) under the
                  provisions of this Agreement, any other Loan Document or
                  otherwise, or

                           (ii) to exercise any right or remedy against any
                  other guarantor of, or collateral securing, any Obligations of
                  any Borrower or any other Obligor;

                  (c) any change in the time, manner or place of payment of, or
         in any other term of, all or any of the Obligations of any Borrower or
         any other Obligor, or any other extension, compromise or renewal of any
         Obligation of any Borrower or any other Obligor;

                  (d) any reduction, limitation, impairment or termination of
         any Obligation of any Borrower or any other Obligor for any reason
         (other than the indefeasible payment in full in cash of such
         Obligation), including any claim of waiver, release, surrender,
         alteration or compromise, and shall not be subject to (and Holdings and
         Intermediate Holdings hereby waive any right to or claim of) any
         defense or setoff, counterclaim, recoupment or termination whatsoever
         by reason of the invalidity, illegality, nongenuineness, irregularity,
         compromise, unenforceability of, or any other event or occurrence
         affecting, any Obligation of any Borrower, any other Obligor or
         otherwise;

                  (e) any amendment to, rescission, waiver, or other
         modification of, or any consent to departure from, any of the other
         terms of this Agreement or any other Loan Document;

                  (f) any addition, exchange, release, surrender or
         non-perfection of any collateral, or any amendment to or waiver or
         release or addition of, or consent to departure from, any other
         guaranty, held by any Lender securing any of the Obligations of any
         Borrower or any other Obligor; or

                  (g) any other circumstance which might otherwise constitute a
         defense available to, or a legal or equitable discharge of, any
         Borrower, any other Obligor, any surety or any guarantor.

         SECTION 10.4. Reinstatement, etc. Holdings and Intermediate Holdings
agree that this Article X shall continue to be effective or be reinstated, as
the case may be, if at any time any payment (in whole or in part) of any of the
Obligations of any Borrower is rescinded or must otherwise be restored by any
Lender upon the insolvency, bankruptcy or reorganization of any Borrower or any
other Obligor or otherwise, all as though such payment had not been made.

                                     -118-
<PAGE>   119

         SECTION 10.5. Waiver, etc. Holdings and Intermediate Holdings hereby
waive promptness, diligence, notice of acceptance and any other notice with
respect to any of the Obligations of any Borrower or any other Obligor and this
Article X and any requirement that the Administrative Agent and any other Lender
protect, secure or perfect or insure any security interest or Lien, or any
property subject thereto, or exhaust any right or take any action against any
Borrower, any other Obligor or any other Person (including any other guarantor)
or entity or any collateral securing the Obligations of any Borrower or any
other Obligor, as the case may be.

         SECTION 10.6. Postponement of Subrogation. Holdings and Intermediate
Holdings agree that they will not exercise any rights which they may acquire by
way of subrogation under this Article X, by any payment made hereunder or
otherwise, until the prior payment, in full and in cash, of all Obligations of
each Borrower and each other Obligor. Any amount paid to Holdings and
Intermediate Holdings on account of any such subrogation rights prior to the
payment in full of all Obligations of each Borrower and each other Obligor shall
be held in trust for the benefit of the Lenders and shall immediately be paid to
the Lenders and credited and applied against the Obligations of each Borrower
and each other Obligor whether matured or unmatured, in accordance with the
terms of this Agreement; provided, however, that if all Obligations of each
Borrower and each other Obligor have been paid in full and all Commitments have
been permanently terminated, each Lender agrees that, at Holdings' and
Intermediate Holdings' request, the Lenders will execute and deliver to Holdings
and Intermediate Holdings appropriate documents (without recourse and without
representation or warranty) necessary to evidence the transfer by subrogation to
Holdings and Intermediate Holdings of an interest in the Obligations of each
Borrower and each other Obligor resulting from such payment by Holdings and
Intermediate Holdings. In furtherance of the foregoing, for so long as any
Obligations of any Borrower or any Commitments remain outstanding, Holdings and
Intermediate Holdings shall refrain from taking any action or commencing any
proceeding against any Borrower or any other Obligor (or its successors or
assigns), whether in connection with a bankruptcy proceeding or otherwise to
recover any amounts in respect of payments made under this Article X to any
Lender.

         SECTION 10.7. Successors, Transferees and Assigns; Transfers of Notes,
etc. Without limiting the generality of Section 11.11, any Lender may assign or
otherwise transfer (in whole or in part) any Obligation of any Borrower held by
it to any other Person, and such other Person shall thereupon become vested with
all rights and benefits in respect thereof granted to such Lender under any Loan
Document (including this Article X) or otherwise, subject, however, to any
contrary provisions in such assignment or transfer, and to the provisions of
Section 11.11 and Article IX of this Agreement.

                                   ARTICLE XI
                            MISCELLANEOUS PROVISIONS

         SECTION 11.1. Waivers, Amendments, etc.XI.1. Waivers, Amendments, etc.
The provisions of each Loan Document may from time to time be amended, modified
or waived, if such amendment, modification or waiver is

                                     -119-
<PAGE>   120

in writing and consented to by Holdings, Intermediate Holdings, the Borrowers
and the Required Lenders; provided, however, that no such amendment,
modification or waiver shall:

                  (a) modify this Section without the consent of all Lenders;

                  (b) increase the aggregate amount of any Credit Extensions
         required to be made by a Lender pursuant to its Commitments, extend the
         final Commitment Termination Date of Credit Extensions made (or
         participated in) by a Lender or reduce any fees described in Article
         III payable to any Lender without the consent of such Lender;

                  (c) extend the final Stated Maturity Date for any Lender's
         Loan, or reduce the principal amount of, rate of interest or fees on
         any Loan or Reimbursement Obligations (which shall in each case include
         the conversion of all or any part of the Obligations into equity of any
         Obligor), or extend the date on which interest or fees are payable in
         respect of such Loan or Reimbursement Obligation, in each case, without
         the consent of the Lender which has made such Loan or, in the case of a
         Reimbursement Obligation, the Issuer owed, and those Lenders
         participating in, such Reimbursement Obligation (it being understood
         and agreed, however, that any vote to rescind any acceleration made
         pursuant to Section 8.2 and Section 8.3 of amounts owing with respect
         to the Loans and other Obligations shall only require the vote of the
         Required Lenders);

                  (d) reduce the percentage set forth in the definition of
         "Required Lenders" or modify any requirement hereunder that any
         particular action be taken by all Lenders without the consent of all
         Lenders;

                  (e) except as otherwise expressly provided in a Loan Document,
         release (i) Holdings, Intermediate Holdings or any Borrower from its
         Obligations under the Loan Documents or any Guarantor from its
         Obligations under a Guaranty or (ii) all or substantially all of the
         collateral under the Loan Documents, in each case without the consent
         of all Lenders;

                  (f) (i) amend, modify or waive clause (b) of Section 3.1.1 or
         (ii) have the effect (either immediately or at some later time) of
         enabling any Borrower to satisfy a condition precedent to the making of
         a Revolving Loan or the issuance of a Letter of Credit unless such
         amendment, modification or waiver shall have been consented to by the
         holders of at least 51% of the Revolving Loan Commitments of the
         applicable Tranche.

                  (g) amend, modify or waive the provisions of clause (a)(i),
         (c) or (d) of Section 3.1.1 or clause (b) of Section 3.1.2, or effect
         any amendment, modification or waiver that by its terms adversely
         affects the rights of Lenders participating in any Tranche differently
         from those of other Lenders participating in other Tranches, unless
         such amendment, modification or waiver shall have been consented to by
         the holders of at least 51% of the aggregate amount of Loans
         outstanding under the Tranche or Tranches affected by such
         modification, or, in the case of a modification affecting any of the

of the applicable Tranche;

                  (h) change any of the terms of clause (e) of Section 2.1.4 or
         Section 2.3.2 without the consent of the Swing Line Lender; or

         either Agent (in its capacity as an Agent) or any Issuer (in its
         capacity as an Issuer), unless consented to by such Agent or such
         Issuer, as the case may be.

No failure or delay on the part of either Agent, any Issuer or any Lender in
exercising any power or right under any Loan Document shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power or right
preclude any other or further exercise thereof or the exercise of any other
power or right. No notice to or demand on any Obligor in any case shall entitle
it to any notice or demand in similar or other circumstances. No waiver or
approval by either Agent, any Issuer or any Lender under any Loan Document
shall, except as may be otherwise stated in such waiver or approval, be
applicable to subsequent transactions. No waiver or approval hereunder shall
require any similar or dissimilar waiver or approval thereafter to be granted
hereunder.

         For purposes of this Section 11.1, the Syndication Agent, in
coordination with the Administrative Agent, shall have primary responsibility,
together with Holdings, Intermediate Holdings and the Borrowers, in the

applicable Person at its address or facsimile number set forth below its
signature in this Agreement or set forth in the Lender Assignment Agreement
pursuant to which it may become a Lender hereunder, or at such other address or
facsimile number as may be designated by any such party in a notice to the other
parties. Any notice, if mailed and properly addressed with postage prepaid or if
properly addressed and sent by pre-paid courier service, shall be deemed given
when received; any notice, if transmitted by facsimile, shall be deemed given
when the confirmation of transmission thereof is received by the transmitter.
Unless otherwise indicated, all references to the time of a day in a Loan
Document shall refer to New York time.

         SECTION 11.3. Payment of Costs and Expenses. Each of Holdings,
Intermediate Holdings and the Company agrees to pay on demand all expenses of

         each Loan Document, including schedules and exhibits, and any
         amendments, waivers, consents, supplements or other modifications to
         any Loan Document as may from time to time hereafter be required,
         whether or not the transactions contemplated hereby are consummated;
         and

                  (b) the filing or recording of any Loan Document (including

         following the Closing Date in jurisdictions where Filing Statements (or
         other documents evidencing Liens in favor of the Secured Parties) have
         been recorded and any and all other documents or instruments of further
         assurance required to be filed or recorded by the terms of any Loan
         Document; and

                  (c) the preparation and review of the form of any document or
         instrument relevant to any Loan Document.

Each of Holdings, Intermediate Holdings and the Company further agrees to pay,
and to save each Secured Party harmless from all liability for, any stamp or
other taxes which may be payable in connection with the execution or delivery of
each Loan Document, the Credit Extensions or the issuance of the Notes. Each of
Holdings, Intermediate Holdings and the Company also agrees to reimburse each
Secured Party upon demand for all reasonable out-of-pocket expenses (including
reasonable attorneys" fees and legal expenses of counsel to each Secured Party)
incurred by such Secured Party in connection with (x) the negotiation of any
restructuring or "work-out" with Holdings, Intermediate Holdings or any
Borrower, whether or not consummated, of any Obligations and (y) the enforcement

                  (a) any transaction financed or to be financed in whole or in
         part, directly or indirectly, with the proceeds of any Credit
         Extension, including all Indemnified Liabilities arising in connection
         with the Transaction;

                  (b) the entering into and performance of any Loan Document by
         any of the Indemnified Parties (including any action brought by or on
         behalf of Holdings, Intermediate Holdings or a Borrower as the result
         of any determination by the Required Lenders

         acquisition or proposed acquisition by any Obligor or any Subsidiary
         thereof of all or any portion of the Capital Stock or assets of any
         Person, whether or not an Indemnified Party is party thereto;

                  (d) any investigation, litigation or proceeding related to any
         environmental cleanup, audit, compliance or other matter relating to
         the protection of the environment on, under or arising from any
         operations or property owned, leased or operated upon (including right
         of way easements) of Holdings or its Subsidiaries or the Release by any
         Obligor or any Subsidiary thereof of any Hazardous Material;

                  (e) the presence on or under, or the escape, seepage, leakage,
         spillage, discharge, emission, discharging or releases from, any
         operations of Obligor or Subsidiary or any real property owned, leased,
         or operated upon (including right of way easements) by any Obligor or
         any Subsidiary thereof of any Hazardous Material (including any losses,
         liabilities, damages, injuries, costs, expenses or claims asserted or
         arising under any Environmental Law), regardless of whether caused by,
         or within the control of, such Obligor or Subsidiary; or

                  (f) each Lender's Environmental Liability (the indemnification
         herein shall survive repayment of the Obligations and any transfer of
         the property of any Obligor or its Subsidiaries by foreclosure or by a
         deed in lieu of foreclosure for any Lender's Environmental Liability,
         regardless of whether caused by, or within the control of, such Obligor
         or such Subsidiary);

except for Indemnified Liabilities arising for the account of a particular
Indemnified Party by reason of the relevant Indemnified Party's gross negligence
or wilful misconduct. Each Obligor and its successors and assigns hereby waive,
release and agree not to make any claim or bring any cost recovery action
against, any Indemnified Party under CERCLA or any state equivalent, or any
similar law now existing or hereafter enacted. It is expressly understood and
agreed that to the extent that any Indemnified Party is strictly liable under
any Environmental Laws, each Obligor's obligation to such Indemnified Party
under this indemnity shall likewise be without regard to fault on the part of
any Obligor with respect to the violation or condition which results in
liability of an Indemnified Party. If and to the extent that the foregoing
undertaking may be unenforceable for any reason, each Obligor agrees to make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law.

Intermediate Holdings and the Borrowers under Sections 4.3, 4.4, 4.5, 4.6, 11.3

case survive any assignment from one Lender to another (in the case of Sections
11.3 and 11.4) and the occurrence of the Termination Date. The representations

                                     -123-
<PAGE>   124

and warranties made by each Obligor in each Loan Document shall survive the
execution and delivery of such Loan Document.

         SECTION 11.6. Severability. Any provision of any Loan Document which is
prohibited or unenforceable in any jurisdiction shall, as to such provision and
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions of such Loan

inserted for convenience only and shall not affect the meaning or interpretation
of such Loan Document or any provisions thereof.

Agreement may be executed by the parties hereto in several counterparts, each of
which shall be an original and all of which shall constitute together but one
and the same agreement. This Agreement shall become effective (the "Effective

Holdings and each Borrower, each Agent and each Lender (or notice thereof
satisfactory to the Agents), shall have been received by the Agents.

         SECTION 11.9. Governing Law; Entire Agreement. EACH LOAN DOCUMENT
(OTHER THAN THE LETTERS OF CREDIT, TO THE EXTENT SPECIFIED BELOW AND EXCEPT AS

         SECTION 11.11.1.  Assignments. Any Lender (an "Assignor Lender"),

                  (a) with the written consents of Holdings, the Agents and (in
         the case of any assignment of U.S. Revolving Loan Commitments and
         related participations in Letters of Credit, Letter of Credit
         Outstandings and Swing Line Loans) the Issuers (which consents (i)
         shall not be unreasonably delayed or withheld, (ii) of Holdings shall
         not be required upon the occurrence and during the continuance of any
         Event of Default and (iii) of the Agents and the Issuers shall not be
         required in the case of any assignment made by DLJ or any of its
         Affiliates), may at any time assign and delegate to one or more
         commercial banks, funds that are regularly engaged in making,
         purchasing or investing in loans or securities, or other financial
         institutions, and

                  (b) with notice to Holdings, the Agents, and (in the case of
         any assignment of U.S. Revolving Loan Commitments and related
         participations in Letters of Credit, Letter of Credit Outstandings and

         its Affiliates or Related Funds or to any other Lender or any Affiliate
         or Related Fund of any other Lender

(each Person described in either of the foregoing clauses as being the Person to
whom such assignment and delegation is to be made, being hereinafter referred to
as an "Assignee Lender"), all or any fraction of such Assignor Lender's Loans
and Commitments (and in the case of any assignment of U.S. Revolving Loan
Commitments, related participations in Letters of Credit, Letter of Credit
Outstandings and Swing Line Loans) (which assignment and delegation shall be,
(i) as among U.S. Revolving Loan Commitments, Revolving Loans and participations
in Letters of Credit, Letter of Credit Outstandings and Swing Line Loans, (ii)
as among Canadian Revolving Loan Commitments and Canadian Loans and (iii) as
among Australian Revolving Loan Commitments and Australian Revolving Loans, in
each case, of a constant, and not a varying, percentage) is in a minimum
aggregate amount of (i) $1,000,000 (provided that (1) assignments that are made
on the same day to funds that (x) invest in commercial loans and (y) are managed
or advised by the same investment advisor or any Affiliate of such investment
advisor may be treated as a single assignment for purposes of the minimum amount
and (2) no minimum amount shall be required in the case of any assignment
between two Lenders (or to any Affiliate or Related Fund of such Assignor
Lender) so long as the Assignor Lender has an aggregate amount of Loans and
Commitments of at least $1,000,000 following such assignment) unless Holdings
and the Agents otherwise consent or (ii) the then remaining amount of such
Assignor Lender's Loans and Commitments; provided, however, that any such
Assignee Lender will comply, if applicable, with the provisions contained in
Section 4.6 and Holdings, each Borrower, each other Obligor and the Agents shall
be entitled to continue to deal solely and directly with such Assignor Lender in
connection with the interests so assigned and delegated to an Assignee Lender
until

                  (c) written notice of such assignment and delegation, together
         with payment instructions, addresses and related information with
         respect to such Assignee Lender, shall

                                     -125-
<PAGE>   126

have been given to Holdings and the Agents by such Assignor Lender and such
Assignee Lender;

                  (d) such Assignee Lender shall have executed and delivered to
         Holdings and the Agents a Lender Assignment Agreement, accepted by the
         Agents;

                  (e) the processing fees described below shall have been paid;
         and

                  (f) the Administrative Agent shall have registered such
         assignment and delegation in the Register pursuant to clause (b) of
         Section 2.7.

From and after the date that the Agents accept such Lender Assignment Agreement
and such assignment and delegation is registered pursuant to clause (b) of
Section 2.7, (x) the Assignee Lender thereunder shall be deemed automatically to
have become a party hereto and to the extent that rights and obligations
hereunder have been assigned and delegated to such Assignee Lender in connection
with such Lender Assignment Agreement, shall have the rights and obligations of
a Lender hereunder and under the other Loan Documents (including the
Intercreditor Agreement), and (y) the Assignor Lender, to the extent that rights
and obligations hereunder have been assigned and delegated by it in connection
with such Lender Assignment Agreement, shall be released from its obligations
hereunder and under the other Loan Documents (including the Intercreditor
Agreement). Any Assignor Lender that shall have previously requested and
received any Note or Notes in respect of any Tranche to which any such
assignment applies shall, upon the acceptance by the Administrative Agent of the
applicable Lender Assignment Agreement, mark such Note or Notes "exchanged" and
deliver them to the applicable Borrower (against, if the Assignor Lender has
retained Loans or Commitments with respect to the applicable Tranche and has
requested replacement Notes pursuant to clause (b)(ii) of Section 2.7, its
receipt from the applicable Borrower of replacement Notes in the principal
amount of the Loans and Commitments of the applicable Tranche retained by it).
Such Assignor Lender or such Assignee Lender (unless the Assignor Lender or the
Assignee Lender is DLJ or one of its Affiliates) must also pay a processing fee
to the Administrative Agent upon delivery of any Lender Assignment Agreement in
the amount of $3,500, unless such assignment and delegation is by a Lender to
its Affiliate or Related Fund or if such assignment and delegation is by a
Lender to a Federal Reserve Bank, as provided below or is otherwise consented to
by the Administrative Agent. Any attempted assignment and delegation not made in
accordance with this Section 11.11.1 shall be null and void. Nothing contained
in this Section 11.11.1 shall prevent or prohibit any Lender from pledging its
rights (but not its obligations to make Loans or participate in Letters of
Credit, Letter of Credit Outstandings or Swing Line Loans) under this Agreement
and/or its Loans hereunder to a Federal Reserve Bank in support of borrowings
made by such Lender from such Federal Reserve Bank and any Lender that is a fund
that invests in bank loans may pledge all or any portion of its rights (but not
its obligations to make Loans or participate in Letters of Credit or Letter of
Credit Outstandings) hereunder to any trustee or any other holder or
representative of holders of obligations owed or securities issued by such fund
as security for such obligations or securities. In the event that S&P, Moody's
or Thompson's BankWatch (or InsuranceWatch Ratings Service, in the case of
Lenders that are insurance companies (or Best's Insurance Reports, if such
insurance company is not rated

                                     -126-
<PAGE>   127

by Insurance Watch Ratings Service)) shall, after the date that any Lender with
a Commitment to make U.S. Revolving Loans or participate in Letters of Credit,
Letter of Credit Outstandings or Swing Line Loans becomes a Lender, downgrade
the long-term certificate of deposit rating or long-term senior unsecured debt
rating of such Lender, and the resulting rating shall be below BBB+, Baa or B
(or BB, in the case of Lender that is an insurance company (or B++, in the case
of an insurance company not rated by InsuranceWatch Ratings Service))
respectively, then the applicable Issuer or Holdings shall have the right, but
not the obligation, upon notice to such Lender and the Agents, to replace such
Lender with an Assignee Lender in accordance with and subject to the
restrictions contained in this Section, and such Lender hereby agrees to
transfer and assign without recourse (in accordance with and subject to the
restrictions contained in this Section) all its interests, rights and
obligations in respect of its U.S. Revolving Loan Commitment under this
Agreement to such Assignee Lender; provided, however, that (i) no such
assignment shall conflict with any law, regulation or order of any governmental
authority and (ii) such Assignee Lender shall pay to such Lender in immediately
available funds on the date of such assignment the principal of and interest and
fees (if any) accrued to the date of payment on the Loans made, and Letters of
Credit participated in, by such Lender hereunder and all other amounts accrued
for such Lender's account or owed to it hereunder.

         SECTION 11.11.2. Participations. Any Lender may sell to one or more
commercial banks or other Persons (each of such commercial banks and other
Persons being herein called a "Participant") participating interests in any of
the Loans, Commitments, or other interests of such Lender hereunder; provided,
however, that

                  (a) no participation contemplated in this Section shall
         relieve such Lender from its Commitments or its other obligations under
         any Loan Document;

                  (b) such Lender shall remain solely responsible for the
         performance of its Commitments and such other obligations;

                  (c) each Obligor and the Administrative Agent shall continue
         to deal solely and directly with such Lender in connection with such
         Lender's rights and obligations under each Loan Document;

                  (d) no Participant, unless such Participant is an Affiliate of
         such Lender or is itself a Lender, shall be entitled to require such
         Lender to take or refrain from taking any action under any Loan
         Document, except that such Lender may agree with any Participant that
         such Lender will not, without such Participant's consent, take any
         actions of the type described in clauses (a), (b), (c) or (f) of
         Section 11.1 with respect to Obligations participated in by such
         Participant; and

                  (e) the Borrowers shall not be required to pay any amount
         under this Agreement that is greater than the amount which it would
         have been required to pay had no participating interest been sold.

                                     -127-
<PAGE>   128

Each Borrower and Holdings acknowledges and agrees that each Participant, for
purposes of Sections 4.3, 4.4, 4.5, 4.6, 4.8, 4.9, 7.1.1, 11.3 and 11.4, shall
be considered a Lender. Each Participant shall only be indemnified for increased
costs pursuant to Section 4.3, 4.5 or 4.6 if and to the extent that the Lender
which sold such participating interest to such Participant concurrently is
entitled to make, and does make, a claim on the applicable Borrower for such
increased costs. Any Lender that sells a participating interest in any Loan,
Commitment or other interest to a Participant under this Section shall indemnify
and hold harmless Holdings and the Borrowers and the Administrative Agent from
and against any taxes, penalties, interest or other costs or losses (including
reasonable attorneys' fees and expenses) incurred or payable by Holdings and the
Borrowers or the Administrative Agent as a result of the failure of Holdings and
the Borrowers or the Administrative Agent to comply with its obligations to
deduct or withhold any Taxes from any payments made pursuant to this Agreement
to such Lender or the Administrative Agent, as the case may be, which Taxes
would not have been incurred or payable if such Participant had been a Non-U.S.
Lender that was entitled to deliver to the Company, the Administrative Agent or
such Lender, and did in fact so deliver, a duly completed and valid Form W-8BEN
or W-8ECI (or applicable successor form) entitling such Participant to receive
payments under this Agreement without deduction or withholding of any United
States federal taxes.

         SECTION 11.12. Other Transactions. Nothing contained herein shall
preclude the Administrative Agent, any Issuer or any other Lender from engaging
in any transaction, in addition to those contemplated by the Loan Documents,
with Holdings, Intermediate Holdings, any Borrower or any of their Affiliates in
which such Obligor or such Affiliate is not restricted hereby from engaging with
any other Person.

         SECTION 11.13. Judgment Currency. (a) If, for the purpose of obtaining
judgment in any court, it is necessary to convert a sum due hereunder (including
under Section 9.1), under any Note or under any other Loan Document in another
currency into U.S. Dollars or into a Foreign Currency, as the case may be, the
parties hereto agree, to the fullest extent that they may effectively do so,
that the rate of exchange used shall be that at which, in accordance with normal
banking procedures, the applicable Secured Party could purchase such other
currency with U.S. Dollars or with such Foreign Currency, as the case may be, in
New York City, New York at the close of business on the Business Day immediately
preceding the day on which final judgment is given, together with any premiums
and costs of exchange payable in connection with such purchase.

         (b) The obligation of each Borrower, Intermediate Holdings and Holdings
in respect of any sum due from it to any Agent or any Lender hereunder, under
any Note or under any other Loan Document shall, notwithstanding any judgment in
a currency other than U.S. Dollars or a Foreign Currency, as the case may be, be
discharged only to the extent that on the Business Day next succeeding receipt
by such Agent or such Lender of any sum adjudged to be so due in such other
currency, such Agent or such Lender may, in accordance with normal banking
procedures, purchase U.S. Dollars or such Foreign Currency, as the case may be,
with such other currency. If the U.S. Dollars or such Foreign Currency so
purchased are less than the sum originally due to such Agent or such Lender in
U.S. Dollars or in such Foreign Currency, such Borrower and

                                     -128-
<PAGE>   129

Holdings agrees, as a separate obligation and notwithstanding any such judgment,
to indemnify such Agent or such Lender against such loss.

         SECTION 11.14. Forum Selection and Consent to Jurisdiction. ANY
LITIGATION BASED HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, ANY
LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER
ORAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE LENDERS, ANY ISSUER OR HOLDINGS
OR ANY BORROWER IN CONNECTION HEREWITH OR THEREWITH MAY BE BROUGHT AND
MAINTAINED IN THE COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES
DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT
