(k) Subsequent to the Execution Time and prior to the Closing Date, there shall not have occurred any downgrading, nor shall any notice have been given of (i) any intended or potential downgrading or (ii) any review or possible change in the rating accorded Union's debt securities by the Rating Agencies as of the Execution Time. - 24 - 25 (l) Prior to the Closing Date, the Companies shall have furnished to you and the Rating Agencies such further information, certificates and documents as you and they may reasonably request.

This indemnity agreement will be in addition to any liability which Union may otherwise have. (b) You severally (and not jointly) agree to indemnify and hold harmless each of the Companies, each of their respective directors, each of their respective officers who signs the Registration Statement, and each person who controls the Companies within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from Union to you, but only with reference to written information relating to you furnished to the Companies by or on behalf of you specifically for use in preparation of the documents referred to in clause (a) of this Section 8. This indemnity agreement will be in addition to any liability which you may otherwise have. The Companies acknowledge that the statements set forth in the last paragraph of the cover page and under the heading "Underwriting" in any Preliminary Prospectus and the Prospectus and the stabilization language included on the inside front cover of any Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of you for inclusion in any Preliminary Prospectus or the Prospectus, and you confirm that such statements are correct. (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 8. In case any such action is brought against any indemnified party, and the indemnified party notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to appoint counsel satisfactory to such indemnified party to represent the indemnified party in such action; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of the indemnifying party's election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified - 26 - 27 party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, approved by you in the case of subparagraph (a), representing the indemnified parties under subparagraph (a) who are parties to such action), (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party; and except that, if clause (i) or (iii) is applicable, such liability shall be only in respect of the counsel referred to in such clause (i) or (iii). (d) In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in paragraph (a) of this Section 8 is due in accordance with its terms but is for any reason held by a court to be unavailable from Union on grounds of policy or otherwise, Union and you shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) to which Union and you may be subject in such proportion so that each of you are responsible only for that portion represented by the percentage that the aggregate underwriting commission in respect of the Pass Through Certificates appearing on the cover page of the Prospectus attributable to Pass Through Certificates sold by you bears to the aggregate public offering price in respect of such Pass Through Certificates appearing thereon and Union is responsible for the balance; provided, however, that (y) in no case shall you be responsible for any amount in excess of such respective underwriting commissions and (z) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls you within the meaning of the Act shall have the same rights to contribution as you, and each person who controls the Companies within the meaning of the Act, each officer of the Companies who shall have signed the Registration Statement and each director of the Companies shall have the same rights to contribution as the Companies, subject in each case to clauses (y) and (z) of this paragraph (d). Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contributions may be made against another party or parties under this paragraph (d), notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this paragraph (d). 9. Termination.
