(f) YRCW has not, without the written consent of TNFINC entered into to any effective amendment, modification or waiver to the Credit Agreement which either (x) grants (or agrees to grant) additional Collateral (as defined therein) to the Credit Agreement Lenders to the extent such Collateral (or agreement to grant) is not required by the Credit Agreement as of the date hereof or (y) requires YRCW to make incremental payments of interest, fees or principal to Credit Agreement Lenders not required as of the date hereof;

(h) YRCW has provided TNFINC written certification on or prior to Friday of each calendar week (and if such Friday is not a business day, the immediately following business day) pursuant to which YRCW certifies that the conditions set forth in clauses (a-c), and (f) are satisfied as of such date.

The extensions set forth in Section 1 shall automatically terminate on the earlier to occur of the failure to satisfy or noncompliance with any of the conditions set forth in this Section 2 (other than 2(e) or other than 2(d) or 2(g), which shall terminate upon giving the required notice) regardless of whether TNFINC has notice or knowledge of such failure or noncompliance, or the date on which YRCW (or any of its subsidiaries) files for protection under Chapter 7 or 11 of the Bankruptcy Code or an involuntary petition for bankruptcy is filed against YRCW (or any of its subsidiaries), but in no event shall the extensions described in Section 1 above extend beyond May 13, 2011 unless extended by TNFINC in its sole discretion at such time (such time period, the “Extension Period”).

writing by TNFINC, the Extension Period and Concessions shall automatically terminate at such time as any of the conditions to extension set forth in this Section 2 (other than 2(e) or other than 2(d) or 2(g), which shall terminate upon giving the required notice) have not been satisfied or waived.

YRCW agrees that, upon the earlier to occur of (i) a Chapter 7 or Chapter 11 petition being filed by or against YRCW (or any of its subsidiaries) or (ii) termination or expiration of the Concessions, the Concessions shall automatically become a claim against YRCW and YRCW shall owe to TNFINC, on behalf of and for the benefit of the IBT members, an amount equal to the value of the Concessions given or provided to YRCW (or any of subsidiaries) prior to the date of such occurrence.

Except as specifically modified in this Certification, all contractual rights provided under the Restructuring Agreement shall remain in full force and effect.

All capitalized terms shall have the meanings set forth in the Restructuring Agreement unless otherwise specified. “Concessions” shall mean the wage, work rule, and pension concessions set forth in the Restructuring Agreement.

The parties to the Credit Agreement may rely on this Certification. This Certification may be signed in one or more counterparts, each of which shall constitute an original, but all of which when taken together shall be considered one document.
