Exhibit 10.1

IRON MOUNTAIN INCORPORATED

Iron Mountain Incorporated 2002 Stock Incentive Plan

Performance Unit Agreement

This Performance Unit Agreement and the associated grant award information (the “Customizing Information”), which Customizing Information is provided in written form or is available in electronic form from the recordkeeper for the Iron Mountain Incorporated 2002 Stock Incentive Plan, as amended and in effect from time to time (the “Plan”), is made as of the date shown as the “Grant Date” in the Customizing Information (the “Grant Date”) by and between Iron Mountain Incorporated, a Delaware corporation (the “Company”), and the individual identified in the Customizing Information (the “Recipient”).  This instrument and the Customizing Information is collectively referred to as the “Performance Unit Agreement.”

WITNESSETH THAT:

WHEREAS, the Company has instituted the Plan; and

WHEREAS, the Compensation Committee (the “Committee”) has authorized the grant of performance units with respect to the Company’s Common Stock (“Stock”) upon the terms and conditions set forth below and pursuant to the Plan, a copy of which is incorporated herein;

NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements herein contained and for other good and valuable consideration the receipt and adequacy of which are hereby acknowledged, the Company and the Recipient agree as follows.

1.  Grant.  Subject to the terms of the Plan and this Performance Unit Agreement, the Company hereby conditionally grants to the Recipient that number of performance units equal to the corresponding number of shares of the Company’s Stock (the “Underlying Shares”) shown in the Customizing Information under “Performance Units Granted.”

The grant described in the preceding paragraph is contingent upon the satisfaction of the “Performance Criteria” over the “Performance Period,” each as shown in the Customizing Information.  The Committee shall determine whether such Performance Criteria have been satisfied.

2.  Adjustment to Award.  The number of Performance Units Granted may be increased or decreased, including to zero, based on the “Performance Matrix” shown in the Customizing Information.  Whether any adjustment based on the Performance Matrix is made shall be determined in the sole discretion of the Committee and the “Adjusted Performance Units Granted” (“PUs”) in the Customizing Information shall be updated to reflect any such adjustment.

3.  Vesting.  If the Recipient remains in an employment, contractual or other service relationship with the Company (“Relationship”) as of the “Vesting Date” specified in the Customizing Information, and the Recipient as of such date is not in violation of any confidentiality, inventions and/or non-competition agreement with the Company, the PUs shall vest on such date.  For the avoidance of doubt, except as otherwise provided pursuant to the terms of the Plan and the next paragraph, if the Recipient’s Relationship with the Company is

terminated by the Company or by the Recipient for any reason, whether voluntarily or involuntarily, no PUs granted pursuant to this Performance Unit Agreement shall vest under any circumstances on and after the date of such termination.

Notwithstanding the preceding paragraph, if the Recipient terminates employment after the end of the Performance Period and on or after attaining age fifty-five (55) and completing ten (10) Years of Credited Service, the Recipient shall become fully vested in the PUs, which shall nevertheless not be delivered until the Vesting Date, as long as the Recipient as of the date of delivery is not in violation of any confidentiality, inventions and/or non-competition agreement with the Company.  For this purpose, a Recipient shall be treated as having terminated from employment if he satisfies the definition of Termination of Employment under the Iron Mountain Incorporated Executive Deferred Compensation Plan, and Years of Credited Service shall be as determined pursuant to and for purposes of The Iron Mountain Companies 401(k) Plan.

For purposes of this Section 3, the term “Company” refers to the Company and all Subsidiaries.

4.  Dividend Equivalents.  A Recipient shall be credited with dividend equivalents equal to the dividends the Recipient would have received if the Recipient had been the actual record owner of the Underlying Shares on each dividend record date on or after the Grant Date and through the date the Recipient receives a settlement pursuant to Section 5 below (the “Dividend Equivalent”).  If a dividend on the Stock is payable wholly or partially in Stock, the Dividend Equivalent representing that portion shall be in the form of additional PUs, credited on a one-for-one basis.  If a dividend on the Stock is payable wholly or partially in cash, the Dividend Equivalent representing that portion shall also be in the form of cash and a Recipient shall be treated as being credited with any cash dividends, without earnings, until settlement pursuant to Section 5 below.  If a dividend on Stock is payable wholly or partially in other than cash or Stock, the Committee may, in its discretion, provide for such Dividend Equivalents with respect to that portion as it deems appropriate under the circumstances.  Dividend Equivalents shall be subject to the same terms and conditions as the PUs originally awarded pursuant to this Performance Unit Agreement, and they shall vest (or, if applicable, be forfeited) as if they had been granted at the same time as the original PU award.  Dividend Equivalents representing the cash portion of a dividend on Stock shall be settled in cash.

5.  Delivery of Underlying Shares or Cash Settlement.  With respect to any PUs that become vested pursuant to Section 3, the Company shall issue and deliver to the Recipient (a) the number of Underlying Shares equal to the number of vested PUs or an amount of cash equal to the Fair Market Value, as defined in the Plan, of such Underlying Shares as of the Vesting Date and (b) the amount (and in the form) due with respect to the Dividend Equivalents applicable to such Underlying Shares.  Delivery shall be made to the Recipient as soon as practicable following the Vesting Date but in no event later than the end of the year in which such Vesting Date occurs (or the fifteenth (15th) day of the third (3rd) month following the Vesting Date, if later).  Whether Underlying Shares, or the cash value thereof, shall be issued or paid at settlement shall be determined based on the “Form of Settlement” specified in the Customizing Information.

Any shares issued pursuant to this Performance Unit Agreement shall be issued, without issue or transfer tax, by delivering a stock certificate or certificates for such shares out of

theretofore authorized but unissued shares or treasury shares of its Stock as the Company may elect; provided, however, that the time of such delivery may be postponed by the Company for such period as may be required for it with reasonable diligence to comply with any applicable requirements of law.  Notwithstanding the prior sentence, delivery of Underlying Shares shall be made, or the amount of cash equivalent thereto shall be paid, only if the required purchase price designated as the “Purchase Price” shown in the Customizing Information per underlying PU is paid to the Company.  Such payment may be made either (i) by means of payment acceptable to the Company in accordance with the terms of the Plan or (ii) by a reduction in the number of shares of Stock, valued at its Fair Market Value, issued hereunder or by a reduction in the amount of cash paid equal in each case to the aggregate Purchase Price due.  If the Recipient fails to pay for or accept delivery of all of the shares, the right to shares of Stock provided pursuant to this PU may be terminated by the Company.

6.  Withholding Taxes.  The Recipient hereby agrees, as a condition of the award of PUs, to provide to the Company an amount sufficient to satisfy the Company’s obligation to withhold federal, state, local and other taxes arising by reason of the issuance, vesting or settlement of PUs and Dividend Equivalents (the “Withholding Amount”), if any, by (a) authorizing the Company and/or any Subsidiary to withhold the Withholding Amount from the Recipient’s cash compensation or (b) remitting the Withholding Amount to the Company in cash; provided, however, that to the extent that the Withholding Amount is not provided by one or a combination of such methods, the Company may at its election withhold from the Underlying Shares and Dividend Equivalents that would otherwise be delivered that number of shares (and/or cash) having a Fair Market Value on the date of vesting sufficient to eliminate any deficiency in the Withholding Amount; and provided, further, that the Fair Market Value of Stock withheld shall not exceed an amount in excess of the minimum required withholding.

7.  Non-assignability of PUs and Dividend Equivalents.  PUs and Dividend Equivalents shall not be assignable or transferable by the Recipient except by will or by the laws of descent and distribution or as permitted by the Committee in its discretion pursuant to the terms of the Plan.  During the life of the Recipient, delivery of shares of Stock or payment of cash as settlement of PUs and Dividend Equivalents shall be made only to the Recipient, to a conservator or guardian duly appointed for the Recipient by reason of the Recipient’s incapacity or to the person appointed by the Recipient in a durable power of attorney acceptable to the Company’s counsel.

8.  Compliance with Securities Act; Lock-Up Agreement.  The Company shall not be obligated to sell or issue any Underlying Shares or other securities in settlement of PUs and Dividend Equivalents hereunder unless the shares of Stock or other securities are at that time effectively registered or exempt from registration under the Securities Act and applicable state securities laws.  In the event shares or other securities shall be delivered that shall not be so registered, the Recipient hereby represents, warrants and agrees that the Recipient will receive such shares or other securities for investment and not with a view to their resale or distribution, and will execute an appropriate investment letter satisfactory to the Company and its counsel.  The Recipient further hereby agrees that as a condition to the settlement of PUs and Dividend Equivalents, the Recipient will execute an agreement in a form acceptable to the Company to the effect that the shares shall be subject to any underwriter’s lock-up agreement in connection with a public offering of any securities of the Company that may from time to time apply to shares

held by officers and employees of the Company, and such agreement or a successor agreement must be in full force and effect.

9.  Legends.  The Recipient hereby acknowledges that the stock certificate or certificates evidencing shares of Stock or other securities issued pursuant to any settlement of an PU or Dividend Equivalent hereunder may bear a legend setting forth the restrictions on their transferability described in Section 8 hereof, if such restrictions are then in effect.

10.  Rights as Stockholder.  The Recipient shall have no rights as a stockholder with respect to any PUs, Dividend Equivalents or Underlying Shares until the date of issuance of a stock certificate for Underlying Shares and any Dividend Equivalents.  Except as provided by Section 4, no adjustment shall be made for any rights for which the record date is prior to the date such stock certificate is issued, except to the extent the Committee so provides, pursuant to the terms of the Plan and upon such terms and conditions it may establish.

11.  Termination or Amendment of Plan.  The Board may terminate or amend the Plan at any time.  No such termination or amendment will affect rights and obligations under this Performance Unit Agreement, to the extent it is then in effect.

12.  Effect Upon Employment and Performance of Services.  Nothing in this Performance Unit Agreement or the Plan shall be construed to impose any obligation upon the Company or any Subsidiary to employ or utilize the services of the Recipient or to retain the Recipient in its employ or to engage or retain the services of the Recipient.

13.  Time for Acceptance.  Unless the Recipient shall evidence acceptance of this Performance Unit Agreement by electronic or other means prescribed by the Committee within sixty (60) days after its delivery, the PUs and Dividend Equivalents shall be null and void (unless waived by the Committee).

14.  Right of Repayment.  In the event that the Recipient accepts employment with or provides services for a competitor of the Company within two (2) years after any settlement of PUs and Dividend Equivalents hereunder, the Recipient shall pay to the Company an amount equal to the excess of the Fair Market Value of the Underlying Shares as of the date of settlement (whether settled in cash or Stock) over the Purchase Price, if any, paid (or deemed paid) together with the value of any Dividend Equivalents; provided, however, that the Committee in its discretion may release the Recipient from the requirement to make such payment, if the Committee determines that the Recipient’s acceptance of such employment or performance of such services is not inimical to the best interests of the Company.  The Company may deduct the amount of payment due under the preceding sentence from any compensation or other amount payable by the Company to the Recipient.  For purposes of this Section 14, the term “Company” refers to the Company and all Subsidiaries.

15.  Section 409A of the Internal Revenue Code.  The PUs and Dividend Equivalents granted hereunder are intended to avoid the potential adverse tax consequences to the Recipient of Section 409A of the Code, as defined in the Plan, and the Committee may make such modifications to this Agreement as it deems necessary or advisable to avoid such adverse tax consequences.

16.  General Provisions.

(a)  Amendment; Waivers.  This Performance Unit Agreement, including the Plan, contains the full and complete understanding and agreement of the parties hereto as to the subject matter hereof, and except as otherwise permitted by the express terms of the Plan and this Performance Unit Agreement, it may not be modified or amended nor may any provision hereof be waived without a further written agreement duly signed by each of the parties; provided, however, that a modification or amendment that does not materially diminish the rights of the Recipient hereunder, as they may exist immediately before the effective date of the modification or amendment, shall be effective upon written notice of its provisions to the Recipient.  The waiver by either of the parties hereto of any provision hereof in any instance shall not operate as a waiver of any other provision hereof or in any other instance.  The Recipient shall have the right to receive, upon request, a written confirmation from the Company of the Customizing Information.
