                           IRON MOUNTAIN INCORPORATED
              IRON MOUNTAIN INCORPORATED 2002 STOCK INCENTIVE PLAN
                             STOCK OPTION AGREEMENT

     This Stock Option 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"), made as of the date shown as the "Grant Date" in the
Customizing Information (the "Grant Date") by and between Iron Mountain
Incorporated, a Pennsylvania corporation (the "Company"), and the individual
identified in the Customizing Information (the "Optionee"). This instrument and
the Customizing Information is collectively referred to as the "Option
Agreement."

                                WITNESSETH THAT:

     WHEREAS, the Company has instituted the Plan; and

     WHEREAS, the Compensation Committee (the "Committee") has authorized the
grant of a stock option upon the terms and conditions set forth below and
pursuant to the Plan, a copy of which is attached hereto and 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
Optionee agree as follows.

     1. GRANT. Subject to the terms of the Plan and this Option Agreement, the
Company hereby grants to the Optionee a stock option (the "Option") to purchase
from the Company the amount of Common Stock ("Stock") shown in the Customizing
Information under "Shares Granted." If so provided in the "Grant Type" shown in
the Customizing Information, this Option is intended to constitute an incentive
stock option and to qualify for special federal income tax treatment under
Section 422 of the Code.

     2. GRANT PRICE. This Option may be exercised at the "Grant Price" per share
shown in the Customizing Information, subject to adjustment as provided herein
and in the Plan.

     3. TERM AND EXERCISABILITY OF OPTION. This Option shall expire on the
"Expiration Date" shown in the Customizing Information, unless the Option
expires earlier pursuant to this Section 3 or any provision of the Plan. At any
time before its expiration, this Option may be exercised to the extent vested,
as shown in the Customizing Information, provided that:

          (a)  at the time of exercise the Optionee is not in violation of any
     confidentiality, inventions and/or non-competition agreement with the
     Company;

          (b)  the Optionee's employment, contractual or other service
     relationship with the Company ("Relationship") must be in effect on a given
     date in order for any scheduled

<Page>

     increment in vesting, as set forth in the "Vesting Schedule" shown in the
     Customizing Information, to become effective; and

          (c)  this Option may not be exercised after the sixtieth (60th) day
     following the date of termination of the Relationship between the Optionee
     and the Company, except that if the Relationship terminates by reason of
     the Optionee's death or total and permanent disability (as determined by
     the Board on the basis of medical advice satisfactory to it), the
     unexercised portion of the Option that is otherwise exercisable on the date
     of termination of the Relationship shall remain exercisable thereafter for
     one (1) year.

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

     4. METHOD OF EXERCISE. Prior to its expiration and to the extent that the
right to purchase shares of Stock has vested hereunder, this Option may be
exercised from time to time by notice acceptable to the Company stating the
number of shares with respect to which this Option is being exercised and
accompanied by either (a) payment in full of the Grant Price for the number of
shares to be delivered, by means of payment acceptable to the Company in
accordance with Section 5(c) of the Plan, or (b) a description of a "cashless
exercise" procedure and such other documents and undertakings as are necessary
to satisfy that procedure. The Company, or the Committee, may from time to time
designate one or more forms or methods of providing notice of the exercise of an
Option and in that event the Optionee agrees to utilize such form or method. As
soon as practicable after its receipt of such notice, the Company shall, without
transfer or issue tax to the Optionee (or other person entitled to exercise this
Option), deliver to the Optionee (or other person entitled to exercise this
Option), at the principal executive offices of the Company or such other place
as shall be mutually acceptable, a stock certificate or certificates for such
shares out of theretofore authorized but unissued shares or reacquired 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.
If the Optionee (or other person entitled to exercise this Option) fails to pay
for and accept delivery of all of the shares specified in such notice upon
tender of delivery thereof, his right to exercise this Option with respect to
such shares not paid for may be terminated by the Company.

     The Committee may, in its discretion at the time of exercise of the Option,
grant to the Optionee a new option (a "Reload Option") to permit the Optionee to
purchase that number of shares of Stock delivered by the Optionee to the Company
in full or partial payment of the Grant Price, or in full or partial payment of
the tax withholding obligations incurred on account of the exercise of the
Option, on such terms and conditions as the Committee may determine under the
terms of the Plan. The Grant Price for shares subject to a Reload Option shall
be not less than one hundred percent (100%) of the Fair Market Value of the
shares on the date of grant of the Reload Option, and the duration of a Reload
Option shall be equal to the unexpired term of the exercised Option on the date
of exercise.

     5. WITHHOLDING TAXES. The Optionee hereby agrees, as a condition to any
exercise of this Option, to provide to the Company an amount sufficient to
satisfy the Company's obligation

                                      - 2 -
<Page>

to withhold federal, state, local and other taxes arising by reason of such
exercise (the "Withholding Amount"), if any, by (a) authorizing the Company
and/or any Subsidiary to withhold the Withholding Amount from his 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 Stock that would otherwise be delivered upon exercise
of this Option that number of shares having a Fair Market Value on the date of
exercise 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 OPTION. This Option shall not be assignable or
transferable by the Optionee except by will or by the laws of descent and
distribution or as permitted by the Committee in its discretion pursuant to the
third sentence of Section 5(h) of the Plan. During the life of the Optionee,
this Option shall be exercisable only by him, by a conservator or guardian duly
appointed for him by reason of the Optionee's incapacity or by the person
appointed by the Optionee 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 shares of Stock or other securities pursuant
to the exercise of this Option unless the shares of Stock or other securities
with respect to which this Option is being exercised 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 issued that shall not be so registered, the Optionee hereby represents,
warrants and agrees that he 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 Optionee further hereby agrees that as a condition to the purchase of shares
upon exercise of this Option, he 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 Optionee hereby acknowledges that the stock certificate or
certificates evidencing shares of Stock or other securities issued pursuant to
any exercise of this Option 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 Optionee shall have no rights as a
stockholder with respect to any shares covered by this Option until the date of
issuance of a stock certificate to him for such 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.

     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 Option, to the extent it is then in effect and
unexercised.

     11. EFFECT UPON EMPLOYMENT AND PERFORMANCE OF SERVICES. Nothing in this
Option or the Plan shall be construed to impose any obligation upon the Company
or any Subsidiary to employ or utilize the services of the Optionee or to retain
the Optionee in its employ or to engage or retain the services of the Optionee.

     12. TIME FOR ACCEPTANCE. Unless the Optionee shall evidence his acceptance
of this Option by electronic or other means prescribed by the Committee within
thirty (30) days after its delivery to him, the Option shall be null and void
(unless waived by the Committee).

     13. NOTICE OF DISQUALIFYING DISPOSITION. If the "Grant Type" shown in the
Customizing Information indicates that the Option is an ISO, the Optionee agrees
to notify the Company promptly in the event that he sells, transfers, exchanges
or otherwise disposes of any shares of Stock issued upon exercise of the Option
before the later of (a) the second anniversary of the date of grant of the
Option and (b) the first anniversary of the date the shares were issued upon his
exercise of the Option.

     14. RIGHT OF REPAYMENT. In the event that the Optionee accepts employment
with or provides services for a competitor of the Company within two (2) years
after the date of exercise of this Option or any portion of it, the Optionee
shall pay to the Company an amount equal to the excess of the Fair Market Value
of the Stock as of the date of exercise over the price paid for such shares;
provided, however, that the Committee in its discretion may release the Optionee
from the requirement to make such payment, if the Committee determines that the
Optionee'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 Optionee. For purposes of this Section 14,
the term "Company" refers to the Company and all Subsidiaries.

     15. GENERAL PROVISIONS.

     by the express terms of the Plan and this Option 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 Optionee 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 Optionee. 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 Optionee shall have the right to receive, upon request, a written
     confirmation from the Company of the Customizing Information.

          (b)  BINDING EFFECT. This Option Agreement shall inure to the benefit
