These 4,104,114 shares of Iron Mountain Common Stock include 1,311,373 shares of
Iron Mountain Common Stock as to which C. Richard Reese shares beneficial

amended, between Schooner and Mr. Reese relating to former services by Mr. Reese
as President of Schooner. Pursuant to such arrangement, upon the earlier to
occur of (i) Schooner's sale or exchange of all or a portion of those 1,311,373
shares, after all other shares of Iron Mountain Common Stock held by Schooner
have been sold, or (ii) the cessation of Mr. Reese's employment with Iron
Mountain, Schooner is required to transfer such shares (or portion thereof) to
Mr. Reese, or remit to Mr. Reese cash in an amount equal to the then current
fair market value of such shares of Iron Mountain Common Stock. Schooner has
agreed to vote the shares of Iron Mountain Common Stock subject to such
arrangement at the direction of Mr. Reese. Thus, Mr. Ryan has sole voting power
with respect to 2,792,741 shares of Iron Mountain Common Stock held by Schooner
and has sole dispositive power with respect to 4,104,114 shares of Iron Mountain
Common Stock held by Schooner. Mr. Ryan individually holds 3,429,073 shares of
Iron Mountain Common Stock. This figure includes 13,911 shares that Mr. Ryan has
the right to acquire pursuant to currently exercisable options or options
becoming exercisable within 60 days of the date of this Schedule 13G. It does
not include 3,041 shares subject to options not yet exercisable. This figure
includes: (a) 102,000 shares registered in the name of The Schooner Foundation,
a private non-profit foundation, of which Mr. Ryan is a Trustee; and (b) 9,000
shares registered in the name of Citibank South Dakota, Trustee of the Ryan 1998
Issue Trust, of which Mr. Ryan was the Settlor.

Item 6.       Ownership of More than Five Percent on Behalf of Another Person.

         C. Richard Reese entered into a deferred compensation agreement, dated
as of December 18, 1995, with Schooner whereby non-qualified stock options to
acquire stock of Schooner pursuant to the Schooner Capital LLC 1988 Stock Option

with deferred compensation of 1,311,373 shares of Iron Mountain Common Stock.
Pursuant to such agreement, upon the earlier to occur of (i) Schooner's sale or
exchange of all or a portion of those 1,311,373 shares after all other shares of

adjusted appropriately to reflect any stock dividend, stock split, or other
equity adjustment with respect to Iron Mountain Common Stock. Mr. Reese has no

adjustments will be made for dividends or other similar stockholder rights for
which the record date is prior to the date such stock certificates are issued.
However, Schooner has agreed to vote the shares of Iron Mountain Common Stock
subject to such arrangements at the direction of Mr. Reese.
