  APPENDIX A    
    
    2008 Transitional Distribution Election    
    

        (1)   A
Director may make an election prior to January 1, 2009 in writing in a manner prescribed by the Plan Administrator to receive the amount credited to his or her
account under the Plan. The election shall specify the calendar date for the payment (herein referred to as the "specified date"). The specified date
cannot be a date in 2008. The election shall be effective only if the Plan Administrator determines that the election and all distributions provided for by the terms of the election will not cause the
Plan as applicable to the Director to violate Code Section 409A under the transitional guidance issued thereunder. 

        (2)   If
the Commencement Date of the Director or the death of the Director occurs before the specified date in the election hereunder, then the amount credited to the account
of the Director shall be paid in accordance with the provisions of Article VI of the Plan based upon the Commencement Date or the death, as the case may be, and the election under this
Appendix A shall be disregarded. 

        (3)   If
the specified date in an effective election by a Director under this Appendix A occurs before both the Commencement Date of the Director and the death of the
Director, then the following shall apply: 

        (a)   The
amount payable under the election shall be the amount credited to the account of the Director under the Plan as of the first day of the calendar month containing the
specified date. 

        (b)   Payment
shall commence to be paid on the date that is 30 days following the specified date or as soon thereafter as administratively feasible. 

        (c)   Payment
shall be paid in the form of a single lump sum if the amount payable to the Director under the election does not exceed the Internal Revenue Code
Section 402(g) limit for the year of distribution ($16,500 in 2009). If the amount payable to the Director under the election exceeds this limit, payment shall be paid in one of the following
forms as elected by the Director in the written election: 

          (i)  a
single lump sum payment; or 

         (ii)  installments
over a period of three years; or 

        (iii)  installments
over a period of five years; or 

        (iv)  installments
over a period of ten years. 

If
payment is being made in installments, the amount payable to the Director under the election shall be adjusted under rules prescribed by the Plan Administrator to reflect the investment experience
of the measurement amount as provided in Section 5.1(b) of the Plan. In the event of the death of the Director before all amounts payable with respect to the election have been paid, the
remaining amount payable shall be paid in a single lump sum to the person or persons entitled to receive the death benefits of the Director under Section 6.4 of the Plan. Payment shall be made
on the date that is 30 days following the date of death or as soon thereafter as administratively feasible. 

        (d)   The
Director shall continue to participate in the Plan following the specified date (subject to the terms of the Plan including the authority of the Company to amend or
terminate the Plan under Section 7.2 of the Plan). At the specified date, the account of the Director in accordance with rules prescribed by the Plan Administrator shall be adjusted to reduce
the account by the amount payable to the Director under the election, so that at anytime after the specified date that the account of the Director becomes payable under the Plan (whether on account of
the 

2

 

Commencement
Date of the Director or the death of the Director), there is no duplicate payment of benefits. 

        (4)   The
Plan Administrator is authorized to interpret this Appendix A and to establish such rules and procedures as it determines necessary or desirable to administer
the Plan with the provisions of this Appendix A, which interpretations, rules and procedures shall be binding upon all those claiming benefits under the Plan. Capitalized terms used in this
Appendix A have the meaning given those terms in the Plan unless otherwise provided in this Appendix A.

 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.    Delivery of Underlying Shares or Cash Settlement.    With respect to any PUs that become vested pursuant to
Section 3, the Company shall issue to the Recipient 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. The Underlying Shares, or the cash value thereof, shall be delivered 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 (a) by means of payment acceptable to the Company in accordance with the terms of the Plan or (b) 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. 

        5.    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 (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
that would otherwise be delivered that number of shares 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. 

        6.    Non-assignability of PUs.    PUs 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 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. 

        7.    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 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 

2

 

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, 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. 

        8.    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 hereunder may bear a legend setting forth the restrictions on their transferability described in Section 7 hereof, if such
restrictions are then in effect. 

        9.    Rights as Stockholder.    The Recipient shall have no rights as a stockholder with respect to any PUs or
Underlying Shares until the date of issuance of a stock certificate for Underlying Shares. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such
stock certificate is issued, except to the extent the Committee determines to issue a Dividend Equivalent Unit, pursuant to the terms of the Plan and upon such terms and conditions it may establish. 

        10.    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. 

        11.    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. 

        12.    Time for Acceptance.    Unless the Recipient shall evidence acceptance of this Performance Unit Agreement by
electronic or other means prescribed by the Committee within thirty (30) days after its delivery, the PUs shall be null and void (unless waived by the Committee). 

        13.    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 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); 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 13, the term "Company" refers to the Company and all Subsidiaries. 

        14.    Section 409A of the Internal Revenue Code.    The PUs 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. 

        15.   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

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. 

        (b)    Binding Effect.    This Performance Unit Agreement shall inure to the benefit of and be binding upon the

shall be rounded down to the nearest penny.

laws of the Commonwealth of Massachusetts, without regard to the principles of conflicts of law.
