Section 5.5. Agreement to Cooperate. (a) Each of the Parties shall use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under Applicable Law to consummate the Merger and make effective the Transactions, including using its reasonable best efforts (i) to prepare and file with the applicable Authorities as promptly as practicable after the execution of this Agreement all requisite applications and amendments thereto, together with related information, data and exhibits, necessary to request issuance of orders approving the Merger and the Transactions by all such applicable Authorities, each of which must be obtained or become final in order to satisfy the condition applicable to it set forth in Section 6.1(c); (ii) to obtain all necessary or appropriate waivers, consents and approvals; (iii) to effect all necessary registrations, filings and submissions (including without limitation filings under federal or state securities laws or the HSR Act and any other submissions requested by the SEC, the FTC or the DOJ); and (iv) to lift any injunction or other legal bar to the Merger and the Transactions.

Each Party covenants and agrees to use its reasonable best efforts to achieve the prompt termination or expiration of any waiting period or any extension thereof under the HSR Act and to obtain any clearance required under the HSR Act for the consummation of the Merger, which efforts, for purposes of this Agreement, shall not require either Party, the Surviving Corporation or any of their respective Subsidiaries in order to obtain any consent or clearance from the DOJ, FTC or any other Authority to hold separate, sell or otherwise dispose of any assets, the effect of any of which, in the reasonable judgment of such Party, would be to materially impair the value of the Merger to such Party. (b) Pierce Leahy will use its reasonable best efforts on or prior to the Closing Date to obtain the satisfaction of the conditions specified in Sections 6.1 and 6.2. Iron Mountain will use <PAGE> 35 its reasonable best efforts on or prior to the Closing Date to obtain the satisfaction of the conditions applicable to it specified in Sections 6.1 and 6.3.

(e) Pierce Leahy and Iron Mountain (i) shall supply consolidated financial statements for it and, to the extent required under Regulation S-X under the Securities Act, any acquired businesses, (and any and all documents and consents related thereto) which comply with Regulation S-X under the Securities Act and the applicable published rules and regulations thereunder for inclusion in any registration statement or other public filing of the other Party under the Securities Act and the Exchange Act, and any other offering circular or document used by Pierce Leahy or Iron Mountain, as the case may be, in any other offering, whether public or private, and (ii) shall use its reasonable best efforts to cause their respective independent accountants to cooperate with the other Party in connection with the foregoing (including, without limitation, using reasonable best efforts to cause such independent accountants to deliver so-called "comfort letters" and written consents relating to the foregoing); provided, however, that Pierce Leahy or Iron Mountain, as the case may be, shall reimburse the other for its reasonable out-of-pocket expenses incurred in connection with its compliance with this Section 5.5(e) (other than with respect to any services that would ordinarily be provided by such accountants). Without limiting the generality of the foregoing, Pierce Leahy and Iron Mountain each agrees that it will (i) consent to the use of such audited financial statements in any such registration statement, document or circular and (ii) execute and deliver, and cause its officers to execute and deliver, such "representation" letters as are customarily delivered in connection with audits and as Pierce Leahy's and Iron Mountain's independent accountants may reasonably request under the circumstances. Section 5.6. Affiliate Agreements; Registration Rights Agreement. (a) Prior to the Closing Date, Iron Mountain shall deliver to Pierce Leahy a letter identifying all Persons who are, at the time this Agreement is submitted to the Stockholders, "affiliates" of Iron Mountain for purposes of Rule 145 under the Securities Act. Iron Mountain shall <PAGE> 36 use its reasonable best efforts to cause each such "affiliate", to deliver to Pierce Leahy on or prior to the Closing Date a written agreement (an "Affiliate Agreement") substantially in the form attached hereto as Exhibit 5.6(a). (b) Pierce Leahy agrees that it will expressly assume the rights and obligations of Iron Mountain under that certain Amended and Restated Registration Rights Agreement dated as of June 12, 1997 among Iron Mountain, certain principal stockholders of Iron Mountain and such other stockholders of Iron Mountain as are party thereto (the "Registration Rights Agreement") with respect to shares of Pierce Leahy Common Stock to be issued in the Merger and that for purposes of the Registration Rights Agreement, Pierce Leahy Common Stock shall be considered "Registrable Securities". Pierce Leahy and Iron Mountain agree that the Registration Rights Agreement will be amended as of the Effective Time to join (the "Registration Rights Agreement Joinder") those Pierce Leahy Principal Shareholders who become party to the Pierce Leahy Shareholders' Agreement on or before November 3, 1999 (together with their Permitted Assignees (as defined in the Pierce Leahy Shareholders' Agreement)), with respect to Subject Shares (as defined in the Pierce Leahy Shareholders' Agreement), for the benefit of such Pierce Leahy Principal Shareholders, which amendment to the Registration Rights Agreement shall be substantially in the form attached hereto as Exhibit 5.6(b). Section 5.7. No Solicitation. (a) Pierce Leahy shall not, nor shall it permit any of its Representatives (including, without limitation, any investment banker, attorney or accountant retained by it) to, initiate, solicit or facilitate, directly or indirectly, any inquiries or the making of any proposal with respect to an Other Transaction, engage in any discussions or negotiations concerning, or provide to any other Person any information or data relating to, Pierce Leahy or any of its Subsidiaries for the purposes of, or otherwise cooperate in any way with or assist or participate in, facilitating any inquiries or the making of any proposal which constitutes, or may reasonably be expected to lead to, a proposal to seek or effect an Other Transaction, or agree to or endorse any Other Transaction; provided, however, that, notwithstanding anything to the contrary in this Agreement, prior to the approval of this Agreement and the Transactions by the Pierce Leahy Shareholders, Pierce Leahy may engage in discussions or negotiations with, and may furnish information concerning Pierce Leahy and its Subsidiaries and their business, properties and assets to, a third party who, without any solicitation, initiation, encouragement, discussion or negotiation, directly or indirectly, by or with Pierce Leahy, any of its Subsidiaries or any of their respective Representatives, or in furtherance thereof makes a written, bona fide proposal regarding an Other Transaction that is not subject to any material contingencies relating to financing and that is reasonably capable of being financed and is financially superior to the consideration to be received by the Pierce Leahy Shareholders pursuant to the Merger (as determined in good faith by Pierce Leahy's Board of Directors after consultation with Pierce Leahy's financial advisors) if (1) Pierce Leahy's Board of Directors determines in good faith, after consultation with Pierce Leahy's outside legal counsel, that such action is required for Pierce Leahy's Board of Directors to act in a manner consistent with its fiduciary duties under Applicable Law and (2) prior to furnishing information with respect to Pierce Leahy and its Subsidiaries to such third party, Pierce Leahy shall have received from such third party an executed confidentiality agreement in reasonably customary form on terms not more favorable to such Entity than the terms contained in the Confidentiality Agreement. Notwithstanding the foregoing, the Board of Directors of Pierce Leahy may take and disclose to the Pierce Leahy Shareholders a position with regard to <PAGE> 37 a tender offer or exchange offer to the extent required by Rule 14e-2(a) under the Exchange Act. In the event of a purported termination of this Agreement by Pierce Leahy pursuant to Section 7.1(c)(ii), any violation prior to such termination of the restrictions set forth in the preceding sentence (after giving effect to the proviso contained therein) by any investment banker or financial advisor retained by Pierce Leahy, whether or not such Person is purporting to act on behalf of Pierce Leahy or any of its Subsidiaries or otherwise, shall be deemed to constitute a breach of this Section 5.7(a) by Pierce Leahy. Pierce Leahy shall promptly advise Iron Mountain of, and (unless the Board of Directors of Pierce Leahy concludes that such disclosure is inconsistent with its fiduciary duties under Applicable Law) communicate the material terms of, any proposal it may receive, or any inquiries it receives which may reasonably be expected to lead to such a proposal relating to an Other Transaction, and the identity of the Person making it. Pierce Leahy shall further advise Iron Mountain of the status and changes in the material terms (unless the Board of Directors of Pierce Leahy concludes that such disclosure is inconsistent with its fiduciary duties under Applicable Law) of any such proposal or inquiry (or any amendment to any of them). During the term of this Agreement, except as contemplated or permitted by this Section 5.7(a), Pierce Leahy shall not enter into any agreement (other than a confidentiality agreement), whether oral or written and whether or not legally binding, with any Person that provides for, or in any way facilitates, an Other Transaction. (b) Iron Mountain shall not, nor shall it permit any of its Representatives (including, without limitation, any investment banker, attorney or accountant retained by it) to, initiate, solicit or facilitate, directly or indirectly, any inquiries or the making of any proposal with respect to an Iron Mountain Transaction, engage in any discussions or negotiations concerning, or provide to any other Person any information or data relating to, Iron Mountain or any of its Subsidiaries for the purposes of, or otherwise cooperate in any way with or assist or participate in, facilitating any inquiries or the making of any proposal which constitutes, or may reasonably be expected to lead to, a proposal to seek or effect an Iron Mountain Transaction, or agree to or endorse any Iron Mountain Transaction; provided, however, that, notwithstanding anything to the contrary in this Agreement, prior to the approval of this Agreement and the Transactions by the Iron Mountain Stockholders, Iron Mountain may engage in discussions or negotiations with, and may furnish information concerning Iron Mountain and its Subsidiaries and their business, properties and assets to, a third party who, without any solicitation, initiation, encouragement, discussion or negotiation, directly or indirectly, by or with Iron Mountain, any of its Subsidiaries or any of their respective Representatives, or in furtherance thereof makes a written, bona fide proposal regarding an Iron Mountain Transaction that is not subject to any material contingencies relating to financing and that is reasonably capable of being financed and is financially superior to the consideration to be received by the Iron Mountain Stockholders pursuant to the Merger (as determined in good faith by Iron Mountain's Board of Directors after consultation with Iron Mountain's financial advisors) if (1) Iron Mountain's Board of Directors determines in good faith, after consultation with Iron Mountain's outside legal counsel, that such action is required for Iron Mountain's Board of Directors to act in a manner consistent with its fiduciary duties under Applicable Law and (2) prior to furnishing information with respect to Iron Mountain and its Subsidiaries to such third party, Iron Mountain shall have received from such third party an executed confidentiality agreement in reasonably customary form on terms not more favorable to such Entity than the terms contained in the Confidentiality Agreement. Notwithstanding the foregoing, the Board of Directors of Iron Mountain may take and disclose to the Iron Mountain Stockholders a position with regard to a tender offer or exchange offer to the extent required by Rule 14e-2(a) under the Exchange Act. In the event of a purported termination of this Agreement by Iron <PAGE> 38 Mountain pursuant to Section 7.1(d)(ii), any violation prior to such termination of the restrictions set forth in the preceding sentence (after giving effect to the proviso contained therein) by any investment banker or financial advisor retained by Iron Mountain, whether or not such Person is purporting to act on behalf of Iron Mountain or any of its Subsidiaries or otherwise, shall be deemed to constitute a breach of this Section 5.7(b) by Iron Mountain. Iron Mountain shall promptly advise Pierce Leahy of, and (unless the Board of Directors of Iron Mountain concludes that such disclosure is inconsistent with its fiduciary duties under Applicable Law) communicate the material terms of, any proposal it may receive, or any inquiries it receives which may reasonably be expected to lead to such a proposal relating to an Iron Mountain Transaction, and the identity of the Person making it.

The Indemnified Parties as a group shall retain only one law firm (plus appropriate local counsel) to represent them with respect to each such Claim unless there is, as determined by counsel to the Indemnified Parties, under applicable <PAGE> 39 standards of professional conduct, a conflict or a reasonable likelihood of a conflict on any significant issue between the positions of any two or more Indemnified Parties, in which event such Indemnified Party shall be entitled to retain separate legal counsel at the expense of the Surviving Corporation. (b) Pierce Leahy, Iron Mountain and the Surviving Corporation shall maintain Pierce Leahy's existing officers' and directors' liability insurance policy for a period of not less than six (6) years after the Closing Date; provided, (i) that the Surviving Corporation may substitute therefor policies of substantially similar coverage and amounts containing terms no less advantageous to such former directors or officers and (ii) if the existing officers' and directors' liability insurance expires or is canceled during such period, the Surviving Corporation will obtain substantially similar officers' and directors' liability insurance to the extent available. Pierce Leahy and Iron Mountain agree that the officers and directors of Pierce Leahy on the Closing Date and their respective heirs and legal representatives shall be third party beneficiaries of this Section 5.8.
