                           IRON MOUNTAIN INCORPORATED
            AMENDED AND RESTATED NON-QUALIFIED STOCK OPTION AGREEMENT

     This Amended and Restated Non-Qualified Stock Option Agreement and the
attached Non-Qualified Stock Option Schedule (together the "Option Agreement")
made as of this ___ day of ________, 19___ (the "Effective Date") by and between
Iron Mountain Incorporated, a Delaware corporation (the "Company"), and the
individual identified on the Non-Qualified Stock Option Schedule attached hereto
(the "Optionee") constitute a consolidated amendment and restatement of each
outstanding Non-Qualified Stock Option Agreement by and between Safesite Records
Management Corporation ("Safesite") and the Optionee (each an "Old Agreement"
and collectively, the "Old Agreements").

                                WITNESSETH THAT:

     WHEREAS, Safesite, has in the past issued one or more non-qualified stock
options to the Optionee; and

     WHEREAS, the Company has instituted the Iron Mountain Incorporated 1995
Stock Incentive Plan, as amended (the "Plan"), a copy of which is attached
hereto and incorporated herein; and

     WHEREAS, on June 12, 1997, Safesite merged with and into Iron
Mountain/Safesite, Inc., a Delaware corporation wholly owned by the Company; and

     WHEREAS, the Company and the Optionee agree that it is desirable to issue
options pursuant to a new agreement under the Plan that represent an amendment,
restatement and consolidation of all outstanding options issued by Safesite to
the Optionee; and

     WHEREAS, the Company and the Optionee agree that each such option shall be
issued pursuant to and subject to the terms and conditions of the Plan;

     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. FORM OF OPTION. The Company hereby affirms that as of the Effective Date
the Optionee holds outstanding stock options (each an "Option") to purchase from
the Company shares of its Common Stock ("Stock") in the amounts indicated on
Line I of the attached Non-Qualified Stock Option Schedule (the "Schedule"). No
Option evidenced by this Option Agreement is intended to be an incentive stock
option or to qualify for special federal income tax treatment under Section 422
of the Internal Revenue Code of 1986, as amended.

     2. OPTION PRICE. Each Option may be exercised at the Exercise Price
specified for such Option on Line J of the Schedule, subject to adjustment as
provided herein and in the Plan.

     3. TERM AND EXERCISABILITY OF OPTION. Each Option will expire ten (10)
years from the original grant date of such Option, as specified in the Schedule
(the "Original Grant Date"),

<Page>

unless the Option earlier expires under this Section 3. At any time before its
expiration, an Option may be exercised to the extent set forth on Line H of the
Schedule, provided that:

          (a)  at the time of exercise the Optionee is not in violation of any
     Employee Confidentiality and Non-Competition Agreement with the Company;
     and

          (b)  the Optionee's employment or other contractual relationship with
     the Company ("Relationship") must be in effect on a given date in order for
     any additional vesting as set forth on Line H of the Schedule to become
     effective; and

          (c)  no Option may 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 each Option that is otherwise exercisable on the
     date of termination of the Relationship shall remain exercisable thereafter
     for no less than one (1) year.

     Subsection (a) shall not apply to an Optionee if the Optionee's
Relationship with the Company is terminated on or before the first anniversary
of the Effective Date. For purposes of this Section 3, the term "Company" refers
to the Company and all Subsidiaries.

     4. METHOD OF EXERCISE. To the extent that the right to purchase shares of
Stock has accrued hereunder, each Option may be exercised from time to time by
written notice to the Company, substantially in the form attached hereto as
Exhibit 1, stating the number of shares with respect to which the Option is
being exercised, and accompanied by either (a) payment in full of the option
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. 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 the Option), deliver to the
Optionee (or other person entitled to exercise the Option), at the principal
executive offices of the Company or such other place as shall be mutually
acceptable, a 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. Payment of the option price
may be made in cash or cash equivalents, or, in accordance with the terms and
conditions of Section 5(c) of the Plan, in whole or in part in shares of Stock
of the Company; provided, however, that the Board reserves the right upon
receipt of any written notice of exercise from the Optionee to require payment
in cash with respect to the shares contemplated in such notice; and provided,
further, that the Optionee may not make payment in shares of Stock that he
acquired upon the earlier exercise of any incentive stock option, unless he has
held the shares until at least two (2) years after the date the incentive stock
option was granted and at least one (1) year after the date the incentive stock
option was exercised. If the Optionee (or other person entitled to exercise the
Option) fails to pay for and accept delivery of all of the shares specified in
such notice upon tender of delivery

                                      - 2 -
<Page>

thereof, his right to exercise the 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 option 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 option 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 an Option, to provide to the Company an amount sufficient to satisfy
its obligation to withhold certain federal, state and local taxes arising by
reason of such exercise (the "Withholding Amount"), if any, by (a) authorizing
the Company to withhold the Withholding Amount from his cash compensation, or
(b) remitting the Withholding Amount to the Company in cash; provided 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
delivered upon exercise of an Option that number of shares having a fair market
value, on the date of exercise, sufficient to eliminate any deficiency in the
Withholding Amount.

     6. NON-ASSIGNABILITY OF OPTION. No Option shall be assignable or
transferable by the Optionee except by will or by the laws of descent and
distribution. During the life of the Optionee, each Option shall be exercisable
only by him, or by a conservator or guardian duly appointed for him by reason of
his 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 an Option unless the shares of Stock or other securities with
respect to which the Option is being exercised are at that time effectively
registered or exempt from registration under the Securities Act of 1933, as
amended, and applicable state securities laws. In the event shares or other
securities shall be issued which 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
precedent to the purchase of shares upon exercise of an 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 an Option may bear a legend setting forth the restrictions on
their transferability described in Section 7 hereof.

                                      - 3 -

     9. RIGHTS AS STOCKHOLDER. The Optionee shall have no rights as a
stockholder with respect to any shares covered by an 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 an Option to the extent it is then in effect and unexercised.

     11. EFFECT UPON EMPLOYMENT. Nothing in any Option or the Plan shall be
construed to impose any obligation upon the Company or any Subsidiary, as
defined in the Plan, to employ 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 execution of the Schedule within thirty (30) days after its
delivery to him, this Option Agreement shall be null and void.

     13. RIGHT OF REPAYMENT. In the event that the Optionee accepts employment
with a competitor of the Company within two (2) years after the date of exercise
of an 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 shares as to which
the Option was exercised on that date, 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 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. This Section 13 shall not apply to an Optionee if the
Optionee's Relationship with the Company is terminated on or before the first
anniversary of the Effective Date. For purposes of this Section 13, the term
"Company" refers to the Company and all Subsidiaries.

     14. GENERAL PROVISIONS.

          (a)  AMENDMENT; WAIVERS. This Option 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 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.

                                      - 4 -

          (b)  BINDING EFFECT. This Option Agreement shall inure to the benefit
     of and be binding upon the parties hereto and their respective heirs,
     executors, administrators, representatives, successors and assigns.

          (c)  GOVERNING LAW. This Option Agreement shall be governed by and
     construed in accordance with the laws of the Commonwealth of Massachusetts.

          (d) CONSTRUCTION. This Option Agreement is to be construed in
     accordance with the terms of the Plan. In case of any conflict between the
     Plan and this Option Agreement, the Plan shall control. The titles of the
     sections of this Option Agreement and of the Plan are included for
     convenience only and shall not be construed as modifying or affecting their
     provisions. The masculine gender shall include both sexes; the singular
     shall include the plural and the plural the singular unless the context
     otherwise requires.
