                           (i) on the last Business Day of each month commencing

         2.2 Paragraph 4B(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 Paragraph 4 to the Note Agreement shall be and hereby is amended by
inserting the following new paragraph at the end of such paragraph 4:

                  "4G. DEFERRED AMOUNTS. (i) 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 (a) each Series I Deferred Principal
         Amount multiplied by a rate per annum equal to 2.00% per annum from the
         date such Series I Deferred Principal Amount is created and determined
         hereunder until the date such Series I Deferred Principal Amount has
         been paid in full plus (b) each Series I Deferred Principal Amount
         multiplied by a rate per annum equal to 1.00% per annum from the date
         such Series I Deferred Principal Amount has been paid in full (through
         voluntary prepayments pursuant to paragraph 4C hereof) to (but not
         including) January 15, 2004 (the amounts referred to in clauses (a) and
         (b) hereof are collectively referred to as "Deferred Principal Amount
         Fees"). Each such voluntary prepayment shall be applied to the earliest
         occurring Series I Deferred Principal Amount and, after the same has
         been paid in full, thereafter to each immediately succeeding Series I
         Deferred Principal Amount until all Series I Deferred Principal Amounts
         have been paid in full. On January 15, 2004, the Company shall pay all
         Series I Deferred Principal Amounts. As used in this paragraph 4G(i),
         "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 paragraph 4G(i), "Series I Deferred Principal Amount" means the
         Series I 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.

                  (ii) 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 section (iii) 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 (a) 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 I
         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 (b) by no later than
         January 15, 2004, (1) the then unpaid balance of the Second Amendment
         Closing Fees multiplied by the Series I Deferred Fee Allocation and (2)
         a deferral fee to the Noteholders in accordance with their pro rata
         portion of the Deferred Fee Amount multiplied by the Series I Deferred
         Fee Allocation at a rate per annum equal to the sum of (x) the Series I
         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 paragraph 4G(ii), "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 Yield-Maintenance Notes) held by such Noteholder
         an amount equal to the Series I Deferred Fee Allocation times the
         amount of such payment.

                  (iii) 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 Yield-Maintenance 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 Paragraph 5A(a) to the Note Agreement shall be and hereby is
amended by inserting new subparagraphs (vii) and (viii) immediately following
subparagraph (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
         (prepared in such format and detail as is required by the Required
         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
         monthly accounting period of the Company and for such historical period
         as is



                                       4
<PAGE>
         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 the 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 Paragraph 5 of the Note Agreement shall be and hereby is amended by
inserting a new paragraph 5T immediately following paragraph 5S thereto which
shall read as follows:

                  "5T. CANADIAN GUARANTY AND COLLATERAL. By no later than May
         31, 2003, the Company shall (i) 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, (ii) 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

         (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 Paragraph 6C of the Note Agreement shall be and hereby is amended
and restated as follows:

                  "(a) Intentionally Omitted.
