         Fee Note or Make-Whole Note:

                           (i) on the last Business Day of each month commencing
                  with January 31, 2003 through April 30, 2003, the Company will
                  prepay the Notes in an aggregate principal amount equal to the

                  with respect thereto;

                           (iii) on January 15, 2004, the Company shall prepay

                  A Note Principal Allocation times the sum of $19,833,332 minus
                  the aggregate amount of principal prepayments in excess, if
                  any, of $19,833,332 made by the Company on the Amortization

                  to this clause (iii) shall in no event be less than zero; and

                           (iv) on the last Business Day of each month

                  with respect thereto."

         2.2 Section 8.1(c) of the Note Agreement shall be and hereby is amended
by deleting the reference to "June 30, 2002" therein and inserting "March 31,
2004" in lieu thereof.

         2.3 Section 8 to the Note Agreement shall be and hereby is amended by
inserting the following new paragraph at the end of such paragraph 4:

                  "Section 8.7 Deferred Amounts. (a) In addition to the rate of
         interest otherwise payable with respect to the Notes and all other
         amounts payable hereunder or in connection herewith, the Company shall
         pay, by no later than January 15, 2004, additional interest to the
         Noteholders in accordance with their respective pro rata principal
         amount in an amount equal to the aggregate of (i) each Series A
         Deferred Principal Amount multiplied by a rate per annum equal to 2.00%
         per annum from the date such Series A Deferred Principal Amount is
         created and determined hereunder until the date such Series A Deferred
         Principal Amount has been paid in full plus (ii) each Series A Deferred
         Principal Amount multiplied by a rate per annum equal to 1.00% per
         annum from the date such Series A Deferred Principal Amount has been
         paid in full (through voluntary prepayments pursuant to Section 8.2
         hereof) to (but not including) January 15, 2004 (the amounts referred
         to in clauses (i) and (ii) hereof are collectively referred to as
         "Deferred Principal Amount Fees"). Each such voluntary prepayment shall
         be applied to the earliest occurring Series A Deferred Principal Amount
         and, after the same has been paid in full, thereafter to each
         immediately succeeding Series A Deferred Principal Amount until all
         Series A Deferred Principal Amounts have been paid in full. On January
         15, 2004, the Company shall pay all Series A Deferred Principal
         Amounts. As used in this Section 8.7(a), "Deferred Principal Amount"
         means, with respect to each monthly repayment of the Amortization Debt
         occurring on or after the Second Amendment Effective Date but prior to
         January 1, 2004, the excess, if any, of (x) $4,958,333 minus (y) the
         actual amount of such repayment; it being understood and agreed that
         each occurrence of such an excess will create a new and independent
         Deferred Principal Amount. As used in this Section 8.7(a), "Series A
         Deferred Principal Amount" means the Series A Note Principal Allocation
         times each Deferred Principal Amount. The Company agrees that in
         connection with any payment of fees payable to the Specified Holders
         similar to the Deferred Principal Amount Fees, the Company shall pay to
         the Noteholders a pro rata amount of such payment.

                 (b) The Company acknowledges that it is required to pay certain
         amendment/closing fees (in addition to and not including the 0.25% fee
         described in subsection (c) below and reimbursement for out of pocket
         costs and expenses) to the Noteholders and the Specified Holders in
         connection with, and as required by, the Second

                                       3
<PAGE>

         Amendment and the amendments to the Specified Agreements in form and
         substance substantially similar to the Second Amendment (the "Second
         Amendment Closing Fees"). In lieu of paying the entire balance of the
         Second Amendment Closing Fees on the Second Amendment Effective Date,
         the Company shall pay (i) on the Second Amendment Effective Date, at
         least $2,000,000 of such Second Amendment Closing Fees and the portion
         of the Second Amendment Closing Fees paid to the Noteholders on the
         Second Amendment Effective Date shall not be less than the Series A
         Deferred Fee Allocation multiplied by the actual amount of the Second
         Amendment Closing Fees paid to the Noteholders and the Specified
         Holders on the Second Amendment Effective Date and (ii) by no later
         than January 15, 2004, (A) the then unpaid balance of the Second
         Amendment Closing Fees multiplied by the Series A Deferred Fee
         Allocation and (B) a deferral fee to the Noteholders in accordance with
         their pro rata portion of the Deferred Fee Amount multiplied by the
         Series A Deferred Fee Allocation at a rate per annum equal to the sum
         of (x) the Series A Applicable Rate plus (y) (i) 2.00% from the Second
         Amendment Effective Date until the date such Deferred Fee Amount has
         been paid in full plus (z) 1.00% on the date immediately prior to the
         day such Deferred Fee Amount balance has been paid in full and for the
         period from the date such Deferred Fee Amount has been paid in full
         until January 15, 2004. As used in this Section 8.7(b), "Deferred Fee
         Amount" means, with respect to the Second Amendment Closing Fees, the
         excess of (a) the actual amount of the Second Amendment Closing Fees
         minus (b) the amount of the Second Amendment Closing Fees paid on the
         Second Amendment Effective Date. The Company agrees that in connection
         with any payment on any date of the Deferred Fee Amount or the deferral
         fee referred to above (or a similar deferral fee to any Specified
         Holder) to any Specified Holder, the Company, on the same date, shall
         pay to each Noteholder pro rata in accordance with the unpaid principal
         amount of Notes (other than the Deferral Fee Notes and the Make-Whole
         Notes) held by such Noteholder an amount equal to the Series A Deferred
         Fee Allocation times the amount of such payment.

                  (c) The Company shall pay, on January 15, 2004, a
         restructuring fee pro rata to each Noteholder, in an amount equal to
         0.25% of the then outstanding principal amount of the Notes (other than
         the Make-Whole Notes and the Deferral Fee Notes) held by such
         Noteholder (it being understood and agreed that such restructuring fee
         shall be non-refundable and is deemed to be fully earned on the Second
         Amendment Effective Date)."

         2.4 Section 7.1(a) to the Note Agreement shall be and hereby is amended
by inserting new subsections (vii) and (viii) immediately following subsection
(vi) thereto which shall read as follows:

                  "(vii) Cash Sources. By no later than fifteen (15) days after
         the end of each monthly accounting period of the Company, the following

         Holder(s)): (a) a statement of projected cash sources and uses of the
         Company and its Subsidiaries for the 13 calendar weeks following the
         end of such monthly accounting period and a report (to the extent
         requested by the Required Holder(s) from time to time) containing
         management's discussion and analysis of such projections and (b) a
         statement of cash sources and uses for the immediately preceding

                                       4
<PAGE>

         monthly accounting period of the Company and for such historical period
         as is reasonably required by the Required Holder(s), in comparative
         form against the figures and for the corresponding date and period in
         the projected cash flow statements required under the foregoing
         subsection (a); the foregoing statements required under subsections (a)
         and (b) being duly certified by the chief financial officer or
         treasurer of the Company.

                  (viii) Fleet Equivalent Increase. Concurrently with the
         delivery of each monthly report and information under the Fleet
         Participation Agreement (including without limitation under Section
         6.1(e)(vii) thereof), the Company shall deliver to each Noteholder
         copies of such reports and information and any other information
         relevant to the calculation and determination of the Fleet Equivalent
         Increase."

         2.5 Section 9 of the Note Agreement shall be and hereby is amended by
inserting a new Section 9.18 immediately following Section 9.17 thereto which
shall read as follows:

                  "Section 9.18. Canadian Guaranty and Collateral. By no later
         than May 31, 2003, the Company shall (a) cause its Canadian Subsidiary
         to execute and deliver to each holder of a Note, a guarantee of the
         Obligations pursuant to a guaranty agreement, or supplement thereto, in
         form and substance satisfactory to the Required Holder(s) and their
         counsel, (b) cause its Canadian Subsidiary to execute and deliver to
         the Collateral Agent a general security agreement, or supplement
         thereto, with a copy to each Noteholder, in form and substance
         satisfactory to the Collateral Agent and its counsel, (c) execute and
         deliver a Pledge Agreement, or supplement thereto, pledging 100% of the

         Required Holder(s) corporate resolutions and other documentation
         (including legal opinions, Personal Property Security Act financing
         statements and such other instruments and documents as are requested
         by, and in form and substance satisfactory to, the Required Holder(s)
         and their counsel) related to the delivery of the foregoing agreements;
         provided that the Company shall not be required to provide that portion
         or amount of collateral described above and evidenced by any of the
         foregoing instruments and documents to the extent but only to the
         extent that delivery of such collateral would cause its Canadian
         Subsidiary's accumulated and undistributed earnings and profits to be
         deemed to be repatriated to the Company or a Domestic Subsidiary for
         U.S. federal income tax purposes and the effect of such repatriation
         would be to cause materially adverse tax consequences for the Company."

         2.6 Section 10.3 of the Note Agreement shall be and hereby is amended
and restated as follows:

                 "(a) Intentionally Omitted.

         arising out of a failure by the Company to deliver a business plan as
         required by Section 6.1(o) thereof)."

         2.10 Schedule B of the Note Agreement shall be and hereby is amended by
inserting the following new defined terms and in the correct alphabetical order
to such schedule:

                  "Amortization Debt" means, at any time the same is to be
         determined, the sum of (i) the outstanding principal amount of the
         Senior Secured Notes (other than the Deferral Fee Notes and the
         Make-Whole Notes) (as each such term is defined in the Intercreditor
         Agreement), as of such time plus (ii) the sum of (1) the outstanding

         of Credit plus (C) the amount of unpaid reimbursement obligations with
         respect to drawings under all Term Letters of Credit (as each such term
         is defined in the Credit Agreement as in effect at the date of the

         "Applicable Margin" means, for each month the same is determined, the

         of the end of the Company's most recently ended fiscal quarter and to
         be paid in the quarter following such occurrence (it being understood
         and agreed that, once in effect, such Leverage Valuation Ratio-based

         identified and defined in Section 10.1(d) of the Fleet Participation
         Agreement) is payable under the Fleet Participation Agreement (a "Fleet
         Equivalent Increase"). Each calculation of the Applicable Margin (1)
         will be determined as of the end of each calendar month (or quarter in
         the case of the applicability of a Leverage Increase) and shall be in
         effect for the next succeeding calendar month (or quarter in the case
         of a Leverage Increase), (2) shall be determined without giving effect
         to, and shall not be additive of, the Applicable Margin determined in
         any previous month and (3) shall be subject to the limitation that the
         amount calculated by adding the sum of the increases specified in the
         foregoing subsections (i), (ii) and (iii) shall not exceed 5.00% for
