definition in the appropriate alphabetical order:

“pro forma basis” shall mean (i) with respect to compliance with any test or
covenant or calculation of any ratio under this Agreement (including, for the
avoidance of doubt, the determination of EBITDA or EBITDAR for the purposes of
Sections 9.09,

{S2542756; 2}    

--------------------------------------------------------------------------------

9.10 and 9.11 hereof), the determination or calculation of any applicable tests
or ratios shall be calculated assuming that all Specified Transactions taking
place subsequent to the first day of the most recently ended four full fiscal
quarters for which internal financial statements are available at such date of
determination and prior to or concurrently with the transaction or initiative
for which such test or covenant or calculation is being made (such period, the
“Test Period”) (and any increase or decrease in EBITDA or EBITDAR and the
component financial definitions used therein attributable to any Specified
Transaction) had occurred on the first day of the Test Period and (ii) whenever
pro forma effect is to be given to a Specified Transaction, the pro forma
calculations shall be made in good faith by an officer of the Parent, consistent
with the application thereof to such Specified Transaction for the period
following consummation of such Specified Transaction and prior to the applicable
date of determination, and include, for the avoidance of doubt, the amount of
cost savings, operating expense reductions, other operating improvements and
synergies projected by the Parent in good faith to be realized as a result of
specified actions taken or with respect to which steps have been initiated, or
are reasonably expected to be initiated, within eighteen (18) months of the
closing or effective date of such Specified Transaction (in the good faith
determination of the Parent) (calculated on a pro forma basis as though such
cost savings, operating expense reductions, other operating improvements and
synergies had been realized during the entirety of the applicable period), net
of the amount of actual benefits realized during such period from such actions;
provided, that the aggregate amount of additions made to EBITDA or EBITDAR for
any four full fiscal quarters pursuant to clause (ii) of this definition shall
not (a) exceed 20.0% of EBITDA or EBITDAR (calculated after giving effect to any
adjustment pursuant to clause (j) of the definition thereof) for such period or
(b) be duplicative of one another.
(b)The definition of “EBITDA” is amended in full to read as follows:

(b)    plus depreciation and amortization expense deducted in determining net
income for such period,
(c)    to the extent not disregarded in determining net income for such period,
plus other non-cash expenses (including minority interest expense) for such
period and minus other income (including interest income) (including gains
attributable to minority interest in its Subsidiaries), for such period,
(d)    plus Interest Expense, plus any amortization of deferred financing
charges, deducted in determining net income for such period,
(e)    plus any provision for, and minus any benefit from, income taxes each as
deducted or added in determining net income for such period,

{S2542756; 2}    

--------------------------------------------------------------------------------

(f)    excluding any extraordinary, exceptional, unusual, infrequently occurring
or nonrecurring gain, loss, charge or expense; restructuring costs, charges,
accruals or reserves (including without limitation losses arising from any
natural disasters, debt extinguishment expenses, foreign currency transaction
losses and losses on investments; and whether or not classified as such under
GAAP); costs and expenses incurred in connection with any strategic initiative
or other Specified Transaction, and any other business optimization expenses
(including, without limitation, incentive costs and expenses relating to any
Specified Transaction or other business optimization program; any integration
costs; and any charge, expense, cost, accrual or reserve of any kind associated
with acquisition-related litigation and settlements thereof); start-up or
initial costs for any project or new division or new line of business; costs
associated with the closure or exiting of any division or line of business;
severance costs and expenses, one-time compensation charges, signing, retention
and completion bonuses and recruiting costs; costs relating to facility or
property disruptions, casualties, natural disasters or shutdowns; costs relating
to the integration, consolidation, pre-opening, opening, closing and conversion
of facilities; costs and expenses incurred in connection with non-ordinary
course product and intellectual property development; costs associated with new
systems design or improvements to IT or accounting functions to protect against
cyberattacks; charge, expense, cost, accrual or reserve associated with any
cyberattack (including any related litigation and settlements thereof);
curtailments or modifications to pension and post-retirement employee benefit
plans (including any settlement of pension liabilities); and professional,
legal, accounting, consulting and other service fees incurred in connection with
any of the foregoing,
(g)     plus losses, and minus gains, on sales of fixed assets (including real
estate) not in the ordinary course of business or on sales of discontinued
operations, each as deducted, or added, in determining net income for such
period, after giving effect to any related charges for, reductions of or
provisions for taxes thereon,
(h)    plus losses, and minus gains, from discontinued operations, each as
deducted, or added, in determining net income for such period (it being
understood that once an operation becomes a discontinued operation it will
remain so for all purposes hereunder),
(i)     plus Recall Transaction Costs deducted in determining net income for
such period; provided, that the aggregate amount of Recall Transaction Costs
that may be added back in the calculation of EBITDA pursuant to this clause
(i) shall not exceed $225,000,000 in the aggregate during the period from
July 2, 2015 through July 2, 2019, and
(j)    plus the aggregate amount of “run-rate” net income for such period
projected by the Parent in good faith attributable to any customer installation
and backlog occurring or existing during such period (or following such period
but prior to the date of determination) (which amount shall be calculated on a
pro forma basis as though the full amount of such net income attributable to
such installation and backlog had been realized

{S2542756; 2}    

--------------------------------------------------------------------------------

from the commencement of such period) plus the amount of cost savings, operating
expense reductions, other operating improvements and synergies as provided under
clause (ii) of the definition of “pro forma basis”; provided that the aggregate
amount included in EBITDA pursuant to this clause (j) for any period shall not
exceed 25% of EBITDA in the aggregate for such period (calculated prior to
giving effect to any adjustment pursuant to this clause (j)).
For the purposes of calculating the Consolidated Leverage Ratio, the Net Secured
Leverage Ratio and the ratios set forth in Sections 9.09, 9.10 and 9.11, the
Parent may at its option (such option to be consistently applied with respect to
each Specified Transaction for purposes of all subsequent calculations), adjust
EBITDA for any relevant period to give effect to any Specified Transaction on a
pro forma basis. For the avoidance of doubt, if the Parent has elected to adjust
EBITDA for any Specified Transaction in accordance with this paragraph, it shall
also elect to adjust Rent Expense for such Specified Transaction in accordance
with the last paragraph of the definition of the term “Rent Expense”.
(c)The definition of “Rent Expense” is amended in full to read as follows:

“Rent Expense” shall mean the consolidated real property rent expense of the
Parent and its Subsidiaries, as determined in accordance with GAAP, it being
understood that (i) common area maintenance charges, any other contingent rent
and any other non-rent charges (including property taxes and insurance
obligations) and (ii) rent expense payable under leases that are treated as
Capital Lease Obligations, shall in each case be excluded from the calculation
of Rent Expense.
For the purposes of calculating the ratios set forth in Sections 9.09, 9.10 and
9.11, the Parent may at its option (such option to be consistently applied with
respect to each Specified Transaction for purposes of all subsequent
calculations), adjust Rent Expense (including for purposes of the calculation of
EBITDAR in the determination of any such ratios) for any relevant period to give
effect to any Specified Transaction on a pro forma basis. For the avoidance of
doubt, if the Parent has elected to adjust Rent Expense for any Specified
Transaction in accordance with this paragraph, it shall also elect to adjust
EBITDA or EBITDAR, as applicable, for such Specified Transaction in accordance
with the last paragraph of the definition of the term “EBITDA”.
(d)The definition of “Specified Transaction” is amended in full to read as
follows:

“Specified Transaction” shall mean any of the following transactions or
initiatives: (a) any Investment that results in a Person becoming a Subsidiary,
(b) (i) any Permitted Acquisition having an Acquisition Consideration of more
than $1,000,000 or (ii) any other acquisition of the stock or other equity
interests of a Person whose assets consist or will consist of data centers or
data storage facilities for use in connection with the records and information
management services, data management services or data

{S2542756; 2}    

--------------------------------------------------------------------------------

center services business or activities of the Parent and its Subsidiaries
(regardless of whether such Person is or becomes a Subsidiary after giving
effect thereto), (c) any sale, transfer or disposition outside the ordinary
course of business involving the sale, transfer or disposition of assets with an
aggregate book value in excess of $1,000,000, (d) any designation of a
Subsidiary that results in a Subsidiary ceasing to be a Subsidiary or any
re-designation of an Unrestricted Subsidiary that results in an Unrestricted
Subsidiary becoming a Subsidiary, (e) any acquisition or Investment constituting
an acquisition of assets or equity constituting a business unit, line of
business or division of another Person and (f) any operating improvement,
restructuring, cost savings initiative or any similar initiative.
(e)Section 9.14(vii) of the Credit Agreement is amended in full to read as
follows:

(vii)    (x) Investments in Persons that are not Subsidiaries of the Parent and
(y) Investments in Subsidiaries of the Parent (to the extent such Investments
are not permitted under clause (v) of this Section 9.14) so long as (A) after
giving effect to any such Investment, the Parent is in compliance on a pro forma
basis with Sections 9.09 through 9.11 hereof, as at the last day of the latest
fiscal quarter and (B) immediately before and after any such Investment, no
Default or Event of Default has occurred and is continuing;

(f)The following is added as Section 12.24 of the Credit Agreement:

SECTION 12.24. Acknowledgement Regarding Any Supported QFCs. To the extent that
the Basic Documents provide support, through a guarantee or otherwise, for
Hedging Agreements or any other agreement or instrument that is a QFC (such
support “QFC Credit Support” and each such QFC a “Supported QFC”), the parties
acknowledge and agree as follows with respect to the resolution power of the
Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act
and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act
(together with the regulations promulgated thereunder, the “U.S. Special
Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support
(with the provisions below applicable notwithstanding that the Basic Documents
and any Supported QFC may in fact be stated to be governed by the laws of the
State of New York and/or of the United States or any other state of the United
States):

In the event a Covered Entity that is party to a Supported QFC (each, a “Covered
Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime,
the transfer of such Supported QFC and the benefit of such QFC Credit Support
(and any interest and obligation in or under such Supported QFC and such QFC
Credit Support, and any rights in property securing such Supported QFC or such
QFC Credit Support) from such Covered Party will be effective to the same extent
as the transfer would be effective under the U.S. Special Resolution Regime if
the Supported QFC and such QFC Credit Support (and any such interest, obligation
and rights in property) were governed by the laws of the United States or a
state of the United States. In the event a Covered Party or a BHC Act Affiliate
of a Covered Party becomes subject to a

{S2542756; 2}    

--------------------------------------------------------------------------------

proceeding under a U.S. Special Resolution Regime, Default Rights under the
Basic Documents that might otherwise apply to such Supported QFC or any QFC
Credit Support that may be exercised against such Covered Party are permitted to
be exercised to no greater extent than such Default Rights could be exercised
under the U.S. Special Resolution Regime if the Supported QFC and the Basic
Documents were governed by the laws of the United States or a state of the
United States. Without limitation of the foregoing, it is understood and agreed
that rights and remedies of the parties with respect to a Defaulting Lender
shall in no event affect the rights of any Covered Party with respect to a
Supported QFC or any QFC Credit Support.
For purposes of this Section 12.24:

“BHC Act Affiliate” of a party shall mean an “affiliate’ (as such term is
defined under, and interpreted in accordance with, 12 U.S.C. 1841(k)) of such
party.
“Covered Entity” shall mean any of the following:
(i)
a “covered entity” as that term is defined in, and interpreted in accordance
with, 12 C.F.R. § 252.82(b);

(ii)
a “covered bank” as that term is defined in, and interpreted in accordance with,
12 C.F.R. § 47.3(b); or

(iii)
a “covered FSI” as that term is defined in, and interpreted in accordance with,
12 C.F.R. § 382.2(b).

“Default Right” shall have the meaning assigned to that term in, and shall be
interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as
applicable.
“QFC” shall have the meaning assigned to the term “qualified financial contract”
in, and shall be interpreted in accordance with, 12 U.S.C. 5390(c)(8)(D).
3.Representations and Warranties.  On and as of the date hereof, each of the
Parent and the Company hereby confirms, reaffirms and restates the
representations and warranties set forth in Section 8 of the Credit Agreement
and the representations and warranties in the Basic Documents mutatis mutandis,
except to the extent that such representations and warranties expressly relate
to a specific earlier date in which case the Parent and the Company each hereby
confirms, reaffirms and restates such representations and warranties as of such
earlier date.  Each of the Parent and the Company represents and warrants that,
after giving effect to this Amendment, no Default or Event of Default has
occurred and is continuing.
 
4.Effectiveness. The amendments set forth in Section 2 of this Amendment shall
become effective as of the date set forth above (the “Amendment Effective Date”)

the product of (a) the sum of (i) the aggregate amount Revolving Commitments of
such Lender plus (ii) the aggregate principal amount of Term Loans of such
Lender multiplied by (b) 0.025%, which fee shall be paid in Dollars in
immediately available funds.
 
5.Valid and Binding.  This Amendment shall be binding upon and inure to the
benefit of each of the parties hereto and their respective successors and
assigns.
 
6.Payment of Expenses.  The Company agrees to pay or reimburse the
Administrative Agent for all out-of-pocket costs and expenses incurred in
connection with the Amendment, any other documents prepared in connection
herewith and the transactions contemplated hereby, including, without
limitation, the reasonable fees and disbursements of counsel.
 
7.Reference to and Effect on the Credit Agreement; Limited Effect.  On and after
the Amendment Effective Date, each reference in the Credit Agreement to “this
Agreement”, “hereunder”, “hereof” or words of like import referring to the
Credit Agreement shall mean and be a reference to the Credit Agreement as
amended hereby.  This Amendment shall not constitute an amendment of any other
provision of the Credit Agreement not expressly referred to herein and shall not
be construed as a waiver or consent to any further or future action on the part
of the Company that would require a waiver or consent of the Lenders, the
Canadian Administrative Agent or the Administrative Agent.  Except as expressly
amended hereby, the provisions of the Credit Agreement are and shall remain in
full force and effect.
 
8.Severability.  Any provision of this Amendment which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

9.Loan Document; Integration.  This Amendment shall constitute a Basic
Document.  This Amendment and the other Basic Documents represent the agreement
of each Borrower, each Subsidiary Guarantor, the Canadian Administrative Agent,
the Administrative Agent and the Lenders with respect to the subject matter
hereof, and there are no promises, undertakings, representations or warranties
by the Canadian Administrative Agent, the Administrative Agent or any Lender
relative to the subject matter hereof not expressly set forth or referred to
herein or in the other Basic Documents.
 
10.GOVERNING LAW.  THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
UNDER THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
 

{S2542756; 2}    

--------------------------------------------------------------------------------

11.Counterparts.  This Amendment may be executed by one or more of the parties
hereto in any number of separate counterparts (which may include counterparts
delivered by facsimile transmission), each of which shall be deemed to be an
original, and all of which taken together shall be deemed to constitute one and
the same instrument.

{S2542756; 2}
