GEHL
COMPANY/MULCAHY
CHANGE IN CONTROL AND SEVERANCE AGREEMENT  

        THIS
AGREEMENT, made and entered into as of the _____day of ___________, 2008, by and between
GEHL COMPANY, a Wisconsin corporation (hereinafter referred to as the “GEHL”),
and _________________________ (hereinafter referred to as the “Executive”). 

W I T N E S S E T H : 

        WHEREAS,
the Executive is employed by GEHL in a key executive capacity, and the Executive’s
services are valuable to the conduct of the business of GEHL; 

        WHEREAS,
the Board of Directors of GEHL (the “Board”) recognizes that circumstances may
arise in which a change in control of GEHL occurs, through acquisition or otherwise,
thereby causing uncertainty about the Executive’s future employment with GEHL without
regard to the Executive’s competence or past contributions, which uncertainty may
result in the loss of valuable services of the Executive to the detriment of GEHL and its
shareholders, and GEHL and the Executive wish to provide reasonable security to the
Executive against changes in the Executive’s relationship with GEHL in the event of
any such change in control; 

        WHEREAS,
GEHL and the Executive are desirous that any proposal for a change in control or
acquisition of GEHL will be considered by the Executive objectively and with reference
only to the best interests of GEHL and its shareholders; 

        WHEREAS,
the Executive will be in a better position to consider GEHL’s best interests if the
Executive is afforded reasonable security, as provided in this Agreement, against altered
conditions of employment which could result from any such change in control or
acquisition; and 

        WHEREAS,
GEHL deems it appropriate to provide the Executive with specified severance benefits, as
provided in this Agreement, in the event of certain termination of the Executive other
than in the context of a Change in Control or acquisition. 

        NOW,
THEREFORE, in consideration of the foregoing and of the mutual covenants and agreements
hereinafter set forth, the parties hereto mutually covenant and agree as follows: 

        Section
1.    Change in Control. In the event a Change in Control, as
defined below, occurs while the Executive is employed by GEHL and this Agreement is in
effect, the Executive shall automatically be entitled to employment by GEHL for two (2)
years after the occurrence of the Change in Control (such two (2)-year term of employment
is hereafter referred to as the “Change in Control Contract Term”). While
employed by GEHL during the Change in Control Contract Term, the Executive shall be
entitled to a base salary, bonus opportunity and other employee benefits substantially
equivalent to those the Executive was entitled to immediately prior to the Change in
Control. In addition, upon the occurrence of a Change in Control, and assuming that the
Executive is in the employ of GEHL at such time or demonstrates that his prior
termination was effected in anticipation of a Change in Control as contemplated by the
succeeding paragraph, (i) the unvested stock options awarded to the Executive under the
GEHL Stock Option Plans shall vest, and (ii) all restrictions limiting the exercise,
transferability, entitlement or incidents of ownership of any outstanding award,
including options, restricted stock, supplemental retirement benefits, deferred
compensation, or other property or rights granted to the Executive after the date of this
Agreement (other than pursuant to plans of general application to salaried employees such
as tax-qualified retirement plans, life insurance and the health plan) shall lapse, and
such awards shall become fully vested and be held by or for the Executive free and clear
of all such restrictions. This provision shall apply to all such property or rights
notwithstanding the provisions of any other plan or agreement.  

            If
the Executive incurs a Separation from Service (as defined below) because the
Executive’s employment shall be terminated by GEHL without Cause (as defined below)
or the Executive shall terminate his employment for Good Reason (as defined below) during
the Change in Control Contract Term, or if GEHL shall terminate the Executive’s
employment without Cause, triggering a Separation from Service, within six (6) months
before the execution of a definitive purchase agreement that ultimately results in a
Change in Control and the Executive shall reasonably demonstrate that such termination was
in connection with or in anticipation of the Change in Control, the Executive shall be
entitled to the following: 

            (iii)               paid
in a lump sum within thirty (30) days of the date of the Executive’s
          Separation from Service or the date that the Executive demonstrates that such
          Separation from Service was in connection with or in anticipation of the Change
          in Control, whichever is applicable:  

	 	(a) 	The
Executive’s base salary as in effect on the Separation from Service                (“Current
Base Salary”) through the Separation from Service to the                extent not
theretofore paid; and 

	 	(b) 	The
pro rata portion (based on the completed months in the calendar year through
               the Separation from Service divided by twelve (12)) of the target bonus
award                that could have been earned by the Executive under GEHL’s
then-existing                bonus plan, ignoring performance requirements and any
requirement that the                Executive be employed through the end of the fiscal
year; and 

            (iv)               paid
in a lump sum on the first business day that is six (6) months after the
          Separation from Service or the later date that the Executive demonstrates that
          such Separation from Service was in connection with or in anticipation of the
          Change in Control, whichever is applicable:  

	 	(c) 	Two
(2) times the sum of (I) the Current Base Salary and (II) the highest bonus
               amount earned by the Executive in any of the five (5) fiscal years which
precede                the year in which the Separation from Service occurs, including
any amounts                deferred; and 

	 	(d) 	The
present value of the Executive’s benefits under Section 2 of the
               Executive’s most current Supplemental Retirement Benefit Agreement
using a                discount rate equal to the interest rate that would be used by the
               Gehl Company Retirement Income Plan “B” to calculate the
amount                of a lump sum distribution to be made on the same date as the
payment hereunder; 

2 

provided, however, that any payments
under (c) and (d) shall be increased with interest from the date that payment is made
under (a) and (b) until the payment is made under (c) and (d), with the rate of interest
announced by M&I Bank, Milwaukee, Wisconsin from time to time as its prime or base
lending rate, such rate to be determined as of the Separation from Service. 

            If
benefits under (a), (b), (c) and (d) above are triggered, the Executive shall also receive
at the expense of GEHL (at the time of entering into the agreement, the executive needs
to irrevocably select one of the following two options by checking the applicable
provision; no subsequent change in the election is permitted): 

	 	___	outplacement
services, on an individualized basis at a level of service commensurate with the Executive’s
most senior status with GEHL during the one hundred eighty (180)-day period prior to the
date of the Change in Control, provided by a nationally recognized senior executive
placement firm selected by GEHL with the consent of the Executive, provided that the cost
to GEHL of such services shall not exceed twenty percent (20%) of the Executive’s
Current Base Salary and provided further that such outplacement services shall cease no
later than December 31 of the second calendar year following the calendar year in which
the Executive’s Separation from Service occurs.  

	 	___	the
lesser of Fifteen Thousand Dollars ($15,000) or twenty percent (20%) of the Executive’s
Current Base Salary, such amount to be paid at the same time as the benefits in (c) and
(d) above with interest credited in the same fashion.  

            If
benefits under the preceding paragraph and under (a), (b), (c) and (d) in the second
preceding paragraph are triggered, in addition, for twenty-four (24) months after the
Separation from Service, GEHL shall provide to the Executive and his family medical
benefits at least substantially equal on a pre-tax basis to those provided to him and his
family just prior to the date of the Change in Control, whether pursuant to a group plan
or individual coverage. Notwithstanding the foregoing, if the Executive obtains employment
during the twenty-four (24)-month period and family medical benefits (substantially
equivalent to those offered by GEHL just prior to the date of the Change in Control) are
available from the new employer, GEHL’s obligation to provide such family medical
benefits shall cease for so long as the Executive remains employed. If the extended
coverage exceeds the applicable “COBRA” continuation period, typically eighteen
(18) months, and if such coverage is provided under a health plan that is subject to Code
Section 105(h), benefits payable under such health plan shall comply with the requirements
of Treasury regulation section 1.409A-3(i)(1)(iv)(A) and (B) and, if necessary, GEHL shall
amend such health plan to comply therewith. 

        In
no event shall the Executive be obligated to seek other employment or take any other
action by way of mitigation of the amounts payable to the Executive under this Agreement
and such amounts shall not be reduced (except to the extent set forth in the immediately
preceding paragraph) whether or not the Executive obtains other employment. In addition,
GEHL will not be entitled to reduce the amounts payable under this Agreement for any
claims or rights it may have against the Executive. 

3 

        “Change
in Control” for the purposes of this Agreement shall be defined as one of the
following: 

	 	i) 	Securities
of GEHL representing thirty percent (30%) or more of the combined                voting
power of GEHL’s then outstanding voting securities are acquired
               pursuant to a tender offer or an exchange offer; or 

	 	ii) 	The
shareholders of GEHL approve a merger or consolidation of GEHL with any
               other corporation as a result of which less than fifty percent (50%) of
the                outstanding voting securities of the surviving or resulting entity are
owned by                the former shareholders of GEHL (other than a shareholder who is
an                “affiliate,” as defined under rules promulgated under the
Securities                Act of 1933, as amended, of any party to such consolidation or
merger); or 

	 	iii) 	The
shareholders of GEHL approve the sale of substantially all of GEHL’s
               assets to a corporation which is not a wholly-owned subsidiary of GEHL; or 

	 	iv) 	Any
person becomes the “beneficial owner,” as defined under rules
               promulgated under the Securities Exchange Act of 1934, as amended,
directly or                indirectly of securities of GEHL representing thirty percent
(30%) or more of                the combined voting power of GEHL’s then outstanding
securities the effect                of which (as determined by the Board) is to take
over control of GEHL; or 

	 	v) 	During
any period of two (2) consecutive years, individuals who, at the                beginning
of such period, constituted the Board cease, for any reason, to                constitute
at least a majority thereof, unless the election or nomination for
               election of each new director was approved by the vote of at least
two-thirds                (2/3) of the directors then still in office who were directors
at the beginning                of the period; 

but only if such event is also a
change in ownership or effective control or a change in the ownership of a substantial
portion of the assets of GEHL as defined by the applicable regulations for Code Section
409A using its default provisions. 

        “Good
Reason” for the purposes of this Agreement shall be defined as the occurrence of any
one of the following events or conditions after, or in anticipation of, the Change in
Control: 

	 	i) 	The
removal of the Executive from, or any failure to re-elect or reappoint the
               Executive to, any of the positions held with GEHL on the date of the
Change in                Control or any other positions with GEHL to which the Executive
shall thereafter                be elected, appointed or assigned, except in connection
with the termination of                his employment for disability, Cause, as a result
of his death or by the                Executive other than for Good Reason; or 

	 	ii) 	A
good faith determination by the Executive that there has been a significant
               adverse change, without the Executive’s written consent, in the
               Executive’s working conditions or status with GEHL from such working
               conditions or status in effect immediately prior to the Change in Control,
               including but not limited to (A) a significant change in the nature or
scope of                the Executive’s authority, powers, functions, duties or
responsibilities,                or (B) a significant reduction in the level of support
services, staff,                secretarial and other assistance, office space and
accoutrements; or 

4 

	 	iii) 	Any
material breach by GEHL of any provision of this Agreement; or 

	 	iv) 	Any
purported termination of the Executive’s employment for Cause by GEHL
               which is determined under Section 13 not to be for conduct encompassed in
the                definition of Cause contained herein; or 

	 	v) 	The
failure of GEHL to obtain an agreement, satisfactory to the Executive, from
               any successor or assign of GEHL, to assume and agree to perform this
Agreement,                as contemplated in Section 3 hereof; or 

	 	vi) 	GEHL’s
requiring the Executive to be based at any office or location which                is not
within a fifty (50) mile radius of West Bend, Wisconsin, except for                travel
reasonably required in the performance of the Executive’s
               responsibilities hereunder, without the Executive’s consent. 

For purposes of this Section, any
good faith determination of Good Reason made by the Executive shall be conclusive. 

            “Separation
from Service” for purposes of this Agreement means the date determined under the
default rules of the applicable regulations for Internal Revenue Code (“Code”)
Section 409A for a separation from service between the Executive and GEHL, with the
exception that the default rule for a bona fide leave of absence for disability is
extended from six (6) months to twenty-nine (29) months. 

        Section
2.    Separation from Service Other Than in the Context of a Change
in Control/Severance. If the Executive incurs a Separation from Service because his
employment is involuntarily terminated by GEHL for any reason other than (i) Cause, (ii)
circumstances under which the Executive would be entitled to the payments provided by
Section 1 hereof or (iii) the Executive’s death or disability, the Executive shall
be entitled to receive, and GEHL shall be obligated to pay, the Executive’s then
Current Base Salary, as in effect immediately prior to such termination, for one (1) full
year from the Executive’s Separation from Service. During such year, the Executive
shall also continue to participate in all group health and welfare benefit plans and
programs of GEHL to the extent that such continued participation is possible under the
general terms and provisions of such plans and programs. In the event that the Executive’s
continued participation in any such plans and programs is barred, and in lieu thereof,
the Executive shall be entitled to receive on a payroll basis during the above period an
amount equal to the sum of the average annual contributions, payments, credits, or
allocations made by GEHL to him, to his account, or on his behalf over the two (2) fiscal
years (or fraction thereof) of GEHL preceding the Separation from Service under such
plans and programs from which his continued participation is barred.  

        Notwithstanding
the foregoing unless the Internal Revenue Service has issued clear guidance that the
definition of Good Reason following a Change in Control does not prevent this Section 2
benefit from being an “involuntary separation” benefit, no cash benefit under
this Section 2 shall be payable until the first business day that is six (6) months after
the Separation from Service, at which time all such delayed payments shall be paid in a
lump sum and credited with interest for the period of the delay at the rate announced by
M&I Bank, Milwaukee, Wisconsin from time to time as its prime or base lending rate
determined as of the Separation from Service. If such clear guidance has been issued, the
six (6) month delay shall only apply to the portion of the Section 2 benefit, if any,
which exceeds the aggregate dollar limitations for an involuntary severance plan exempt
from Code Section 409A under the applicable regulations thereof. 

5 

        Termination
by GEHL for “Cause” shall mean termination by action of the Board because of the
material failure of the Executive to fulfill his obligations as an officer of GEHL or
because of serious willful misconduct by the Executive in respect of his obligations as an
officer of GEHL as, for example, the commission by the Executive of a felony or the
perpetration by the Executive of a common-law fraud against GEHL or any major material
action (i.e., not procedural or operational differences) taken against the expressed
directive of the Board. 

        Section
3.    Assigns and Successors. The rights and obligations of GEHL
under this Agreement shall inure to the benefit of and shall be binding upon the
successors and assigns of GEHL and GEHL shall require any successor or assign (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to expressly assume
and agree to perform this Agreement in the same manner and to the same extent that GEHL
would be required to perform if no such succession or assignment had taken place.  

        Section
4.    Construction. Section headings are for convenience only and
shall not be considered a part of the terms and provisions of this Agreement.  

        Section
5.    Notices. All notices under this Agreement shall be in
writing and shall be deemed effective when delivered in person (in GEHL’s case, to
its Secretary, or to its Chief Executive Officer if the Executive is then serving as
Secretary) or by facsimile to the number provided for such purpose by the applicable
party or forty-eight (48) hours after deposit thereof in the U.S. mails, postage prepaid,
addressed, in the case of the Executive, to his last known address as carried on the
personnel records of GEHL and, in the case of GEHL, to the corporate headquarters,
attention of the Secretary, or to its Chief Executive Officer if the Executive is then
serving as Secretary, or to such other address as the party to be notified may specify by
notice to the other party.  

        Section
6.    Severability. Should it be determined that one or more of
the clauses of this Agreement is (are) found to be unenforceable, illegal, contrary to
public policy, etc., this Agreement shall remain in full force and effect except for the
unenforceable, illegal, or contrary to public policy provisions.  

        Section
7.    Limitation on Payments.  

	 	(a) 	Notwithstanding
anything contained herein to the contrary, prior to the payment                of any
amounts pursuant to Sections 1 or 2 hereof, a national accounting firm
               designated by GEHL (the “Accounting Firm”) shall compute whether
there                would be any “excess parachute payments” payable to the
Executive,                within the meaning of Code Section 280G, taking into account
the total                “parachute payments,” within the meaning of Code
Section 280G, payable                to the Executive by GEHL or any successor thereto
under this Agreement and any                other plan, agreement or otherwise. If there
would be any excess parachute                payments, the Accounting Firm will compute
the net after-tax proceeds to the                Executive, taking into account the
excise tax imposed by Code Section 4999, if                (i) the payments hereunder
were reduced, but not below zero, such that the total                parachute payments
payable to the Executive would not exceed three (3) times the                “base
amount” as defined in Code Section 280G, less One Dollar ($1.00)                or
(ii) the payments hereunder were not reduced. If reducing the payments
               hereunder would result in a greater after-tax amount to the Executive,
such                lesser amount shall be paid to the Executive. If not reducing the
payments                hereunder would result in a greater after-tax amount to the
Executive, such                payments shall not be reduced. The determination by the
Accounting Firm shall be                binding upon GEHL and the Executive. 

6 

	 	(b) 	As
a result of the uncertainty in the application of Code Section 280G, it is
               possible that excess parachute payments will be paid when such payment
would                result in a lesser after-tax amount to the Executive; this is not
the intent                hereof. In such cases, the payment of any excess parachute
payments will be void                ab initio as regards any such excess. Any excess
will be treated as a loan by                GEHL to the Executive. The Executive will
return the excess to GEHL, within                fifteen (15) business days of any
determination by the Accounting Firm that                excess parachute payments have
been paid when not so intended, with interest at                an annual rate equal to
the rate provided in Code Section 1274(d) (or one                hundred twenty percent
(120%) of such rate if the Accounting Firm determines                that such rate is
necessary to avoid an excise tax under Code Section 4999) from                the date
the Executive received the excess until it is repaid to GEHL. 

	 	(c) 	All
fees, costs and expenses (including, but not limited to, the cost of
               retaining experts) of the Accounting Firm shall be borne by GEHL and GEHL
shall                pay such fees, costs and expenses as they become due. In performing
the                computations required hereunder, the Accounting Firm shall assume that
taxes                will be paid for state and federal purposes at the highest possible
marginal tax                rates which could be applicable to the Executive in the year
of receipt of the                payments, unless the Executive agrees otherwise. 

        Section
8.    Confidentiality. During and following the Executive’s
employment by GEHL, the Executive shall hold in confidence and not directly or indirectly
disclose or use or copy or make lists of any confidential information or proprietary data
of GEHL except to the extent authorized in writing by the Board or required by any court
or administrative agency, other than to an employee of GEHL or a person to whom
disclosure is reasonably necessary or appropriate in connection with the performance by
the Executive of his duties as an executive of GEHL. Confidential information shall not
include any information known generally to the public or any information of a type not
otherwise considered confidential by persons engaged in the same business or a business
similar to that of GEHL. All records, files, documents and materials, or copies thereof,
relating to the business of GEHL which the Executive shall prepare, or use, or come into
contact with, shall be and remain the sole property of GEHL and shall be promptly
returned to GEHL upon Separation from Service.  

7 

        Section
9.    Expenses and Interest. If (i) a dispute arises with respect
to the enforcement of the Executive’s rights under this Agreement, (ii) any legal or
arbitration proceeding shall be brought to enforce or interpret any provision contained
herein or to recover damages for breach hereof, or (iii) any tax audit or proceeding is
commenced that is attributable in part to the application of Code Section 4999, in any
case so long as the Executive is not acting in bad faith, then GEHL shall reimburse the
Executive for any reasonable attorneys’ fees and necessary costs and disbursements
incurred as a result of such dispute, legal or arbitration proceeding or tax audit or
proceeding (“Expenses”), and prejudgment interest on any money judgment or
arbitration award obtained by the Executive calculated at the rate of interest announced
by M&I Bank, Milwaukee, Wisconsin, from time to time as its prime or base lending
rate from the date that payments to the Executive should have been made under this
Agreement. Within ten (10) days after the Executive’s written request therefor, GEHL
shall pay to the Executive, or such other person or entity as the Executive may designate
in writing to GEHL, the Executive’s reasonable Expenses in advance of the final
disposition or conclusion of any such dispute, legal or arbitration proceeding. Any such
payment shall be made promptly following the date of the final determination that the
Executive is not acting in bad faith, but no later than the end of the calendar year
following the year in which the Executive incurs the expense.  

        Section
10.    Payment Obligations Absolute. GEHL’s obligation to
pay the Executive any amounts required hereunder and to make the benefit and other
arrangements provided herein shall be absolute and unconditional and shall not be
affected by any circumstances, including, without limitation, any setoff, counterclaim,
recoupment, defense or other right which GEHL may have against the Executive or anyone
else. Except as provided in Section 9, all amounts payable by GEHL hereunder shall be
paid without notice or demand. Each and every payment made hereunder by GEHL shall be
final, and GEHL will not seek to recover all or any part of such payment from the
Executive, or from whomsoever may be entitled thereto, for any reason whatsoever.  

        Section
11.    No Waiver. The Executive’s or GEHL’s failure to
insist upon strict compliance with any provision of this Agreement or the failure to
assert any right the Executive or GEHL may have hereunder, including, without limitation,
the right of the Executive to terminate employment for Good Reason, shall not be deemed
to be a waiver of such provision or right or any other provision or right of this
Agreement.  

        Section
12.    Headings. The headings herein contained are for reference
only and shall not affect the meaning or interpretation of any provision of this
Agreement.  

        Section
13.    Governing Law; Resolution of Disputes. This Agreement and
the rights and obligations hereunder shall be governed by and construed in accordance
with the laws of the State of Wisconsin. Any dispute arising out of this Agreement shall,
at the Executive’s election, be determined by arbitration under the rules of the
American Arbitration Association then in effect (in which case both parties shall be
bound by the arbitration award) or by litigation. Whether the dispute is to be settled by
arbitration or litigation, the venue for the arbitration or litigation shall be West
Bend, Wisconsin or, at the Executive’s election, if the Executive is no longer
residing or working in the West Bend, Wisconsin metropolitan area, in the judicial
district encompassing the city in which the Executive resides; provided, that,
if the Executive is not then residing in the United States, the election of the Executive
with respect to such venue shall be either West Bend, Wisconsin or in the judicial
district encompassing that city in the United States among the thirty cities having the
largest population (as determined by the most recent United States Census data available
at the Separation from Service) which is closest to the Executive’s residence. The
parties consent to personal jurisdiction in each trial court in the selected venue having
subject matter jurisdiction notwithstanding their residence or situs, and each party
irrevocably consents to service of process in the manner provided hereunder for the
giving of notices.  

8 

        Section
14.    409A. 

	 	(a) 	If
an amount or the value of a benefit under this Agreement is required to be
               included in an Executive’s income prior to the date such amount is
actually                distributed or benefit provided as a result of the failure of
this Agreement (or                any other arrangement required to be aggregated with
this Agreement under Code                Section 409A) to comply with Code Section 409A,
then the Executive shall receive                a distribution, in a lump sum, within
ninety (90) days after the date it is                finally determined that the
Agreement fails to meet the requirements of Code                Section 409A; such
distribution shall equal the amount required to be included                in the
Executive’s income as a result of such failure and shall reduce the
               amount of payments or benefits otherwise due hereunder. 

	 	(b) 	GEHL
and the Executive intend the terms of this Agreement to be in compliance
               with Code Section 409A. GEHL does not guarantee the tax treatment or tax
               consequences associated with any payment or benefit, including but not
limited                to consequences related to Code Section 409A. To the maximum
extent permissible,                any ambiguous terms of this Agreement shall be
interpreted in a manner which                avoids a violation of Code Section 409A. 

	 	(c) 	The
Executive acknowledges that to avoid an additional tax on payments that may
               be payable or benefits that may be provided under this Agreement and that
               constitute deferred compensation that is not exempt from Code Section
409A, the                Executive must make a reasonable, good faith effort to collect
any payment or                benefit to which the Executive believes the Executive is
entitled hereunder no                later than ninety (90) days after the latest date
upon which the payment could                have been made or benefit provided under this
Agreement, and if not paid or                provided, must take further enforcement
measures within one hundred eighty (180)                days after such latest date. 

	 	(d) 	The
Executive acknowledges that in the discretion of GEHL a portion of the
               benefits hereunder may be accelerated up to the amount of the withholding
               requirement for taxes under Code Section 3121(v) (i.e., FICA taxes)
related to                the benefits hereunder; any such acceleration shall reduce the
amount of                payments otherwise due hereunder.

        Section
15.    Amendment. No modification or amendment to this Agreement
may be made without the written consent of the parties hereto.  

        IN
WITNESS WHEREOF, GEHL COMPANY has caused this Agreement to be executed by its duly
authorized officer, and the Executive has hereunto set his hand, all as of the date set
forth above.

      FORM AND TERMS OF
THE NOTES

       

      Section
2.1.  Form
and Dating

       

      (a)  General.  The
Notes and the Trustee’s certificate of authentication shall be substantially in
the form of Exhibit A attached hereto.  The Notes may have notations,

authentication.  The Notes shall be in denominations of $2,000 and
integral multiples of $1,000 in excess thereof.

       

      The terms and
provisions contained in the Notes shall constitute, and are hereby expressly
made, a part of the Seventh Supplemental Indenture and the Indenture, and the
Company, the Guarantors and the Trustee, by their execution and delivery of the
Seventh Supplemental Indenture and the Indenture (or in the case of any
Guarantor that becomes such after the date hereof, a supplemental indenture
pursuant to Section 2.6(g) of this Seventh Supplemental Indenture (Section 4.14
of the

expressly agree to such terms and provisions and to be bound
thereby.  However, to the extent any provision of any Note conflicts
with the express provisions of the Indenture (as supplemented by this Seventh
Supplemental Indenture), the provisions of the Indenture shall govern and be
controlling.

       

      (b)  Global Notes. Notes shall be issued
initially in the form of the Global Notes, which shall be deposited on behalf of
the purchasers of the Notes represented thereby with the Depository at its New
York office, and registered in the name of the Depository or a nominee of the
Depository, duly executed by the Company and authenticated by the Trustee as
hereinafter provided.  The aggregate principal amount of the Global
Notes may from time to time be increased or decreased by adjustments made on the
records of the Trustee and the Depository or its nominee as hereinafter
provided.

       

      Each Global Note
shall represent such of the outstanding Notes as shall be specified therein, and
each shall provide that it represents the aggregate principal amount of
outstanding Notes from time to time endorsed thereon and that the aggregate
amount of outstanding Notes represented thereby may from time to time be reduced
or increased, as appropriate, to reflect exchanges and
redemptions.  Any endorsement of a Global Note to reflect the amount
of any increase or decrease in the aggregate principal amount of outstanding
Notes represented thereby shall be made by the Trustee or the Service Agent, at
the direction of the Trustee, in accordance with instructions given by the
Holder thereof as required by Section 2.4 hereof.

       

      (c)  Book-Entry
Provisions. This

name of the Depository or the nominee of the Depository and (ii) shall be
delivered by the Trustee to the Depository or pursuant to the Depository’s
instructions or held by the Service Agent.

       

      Agent Members
shall have no rights either under the Seventh Supplemental Indenture or the
Indenture with respect to any Global Notes held on their behalf by the
Depository or by the Service Agent or under such Global Notes, and the
Depository may be treated by the Company, the Trustee and any agent of the
Company or the Trustee as the absolute owner of such Global Notes for all
purposes whatsoever.

       

      (d)  Definitive Note.  Notes issued in
certificated form shall be substantially in the form of Exhibit A attached
hereto (but without including the text referred to in Section 2.15.3 of the
Indenture).  Except as provided in Section 2.4, owners of beneficial
interests in the Global Notes will not be entitled to receive physical delivery
of certificated Securities.

       

      Section
2.2.  Execution and
Authentication.

       

      The Trustee
shall, upon a written order of the Company signed by an Officer, authenticate up
to $300,000,000 aggregate principal amount of Initial Notes and such amount of
Additional Notes as the Company may issue from time to time.

       

      Section
2.3.  Depository and Paying Agent
for Notes.

      Section
2.4.  Transfer and Exchange of
Notes.

       

      (a)  Transfer and Exchange of Global
Notes.  The transfer and
exchange of beneficial interests in the Global Notes shall be effected through
the Depository, in accordance with the Seventh Supplemental Indenture and the
Indenture and the procedures of the Depository therefor.  Beneficial
interests in the Global Notes may be transferred to Persons who take delivery
thereof in the form of a beneficial interest in the Global Notes.

       

      (b)  Transfer and Exchange of
Definitive Notes.  When Definitive
Notes are presented by a Holder to the Registrar with a request:

       

      (x) to register the transfer of the Definitive
Notes; or

       

      (y) to exchange such Definitive Notes for an
equal principal amount of Definitive Notes of other authorized denominations,
the Registrar shall register the transfer or make the exchange as requested if
its requirements for such transactions are met; provided, however, that the
Definitive Notes presented or surrendered for register of transfer or exchange
shall be duly endorsed or accompanied by a written instruction of transfer in
form satisfactory to the Registrar duly executed by such Holder or by his
attorney, duly authorized in writing.

       

      (c)  Restrictions on Transfer and
Exchange of Global Notes.

       

      Notwithstanding
any other provision of the Seventh Supplemental Indenture or the Indenture
(other than the provisions set forth in subsection (d) of this Section 2.4), the
Global Notes may not be transferred as a whole except by the Depository to a
nominee of the Depository, by a nominee of the Depository to the Depository or
to another nominee of the Depository, or by the Depository or any such nominee
to a successor Depository or a nominee of such successor
Depository.

       

      (d)  Authentication of Definitive
Notes in Absence of Depository.  If at any
time:

       

      (i) the Depository for the Notes notifies the
Company that the Depository is unwilling or unable to continue as Depository for
the Global Notes and a successor Depository for the Global Notes is not
appointed by the Company within 90 days after delivery of such notice;
or

       

      (ii) the Company at its sole discretion,
notifies the Trustee in writing that it elects to cause the issuance of
Definitive Notes under the Seventh Supplemental Indenture and the
Indenture,

       

      then the Company
shall execute, and the Trustee shall, upon receipt of an authentication order in
accordance with Section 2.2 hereof, authenticate and deliver, Definitive Notes
in an aggregate principal amount equal to the principal amount of the Global
Notes in exchange for such Global Notes.

       

      (e)  Cancellation and/or Adjustment
of the Global Notes.  At such time as
all beneficial interests in a particular Global Note have been exchanged for
Definitive Notes or a particular Global Note has been redeemed, repurchased or
canceled in whole and not in part, each such Global Note shall be returned to or
retained and canceled by the Trustee in accordance with Section 2.12 of the
Indenture.  At any time prior to such cancellation, if any beneficial
interest in a Global Note is exchanged for or transferred to a Person who will
take delivery thereof in the form of a beneficial interest in another Global
Note or for Definitive Notes, the principal amount of Notes represented by the
Global Note shall be reduced accordingly and an endorsement shall be made on
such Global Note by the Trustee or by the Depository at the direction of the

      §
3.9  Asset

      In the event that
the Company shall commence an Asset Sale Offer pursuant to Section 4.17 hereof,
it shall follow the procedures specified below:

       

      The Asset Sale
Offer shall remain open for 20 Business Days after the Commencement Date
relating to such Asset Sale Offer, except to the extent required to be extended
by applicable law (as so extended, the “Offer Period”).  No later than
one Business Day after the termination of the Offer Period (the “Purchase
Date”), the Company shall purchase the principal amount (the “Offer Amount”) of
Notes required to be purchased in such Asset Sale Offer pursuant to Sections 3.2
and 4.17 hereof or, if less than the Offer Amount has been tendered, all Notes
tendered in response to the Asset Sale Offer.

       

      If the Purchase
Date is on or after an interest payment record date and on or before the related
interest payment date, any interest accrued to such Purchase Date shall be paid
to the Person in whose name a Note is registered at the close of business on
such record date, and no additional interest shall be payable to Holders who
tender Notes pursuant to the Asset Sale Offer.

       

      On the
Commencement Date of any Asset Sale Offer, the Company shall send or cause to be
sent, by first class mail, a notice to each of the Holders, with a copy to the
Trustee.  Such notice, which

      shall govern the
terms of the Asset Sale Offer, shall contain all instructions and materials
necessary to enable the Holders to tender Notes pursuant to the Asset Sale Offer
and shall state:

       

      
        	
                 
      

              	
                (1)

              	
                that the
      Asset Sale Offer is being made pursuant to this Section 3.9 and Section
      4.17 hereof and the length of time the Asset Sale Offer shall remain
      open;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                the Offer
      Amount, the purchase price and the Purchase
  Date;

              

      

       

      
        	
                 
      

              	
                (3)

              	
                that any
      Note not tendered or accepted for payment shall continue to accrue
      interest;

              

      

       

      
        	
                 
      

              	
                (4)

              	
                that,
      unless the Company defaults in the payment of the purchase price, any Note
      accepted for payment pursuant to the Asset Sale Offer shall cease to
      accrue interest after the Purchase
Date;

              

      

       

      
        	
                 
      

              	
                (5)

              	
                that
      Holders electing to have a Note purchased pursuant to any Asset Sale Offer
      shall be required to surrender the Note, with the form entitled “Option of
      Holder to Elect Purchase” on the reverse of the Note completed, to the
      Company, a depositary, if appointed by the Company, or a Paying Agent at
      the address specified in the notice prior to the close of business on the
      Business Day preceding the Purchase
Date;

              

      

       

      
        	
                 
      

              	
                (6)

              	
                that
      Holders shall be entitled to withdraw their election if the Company,
      depositary or Paying Agent, as the case may be, receives, not later than
      the close of business on the Business Day preceding the termination of the
      Offer Period, a facsimile transmission or letter setting forth the name of
      the Holder, the principal amount of the Note the Holder delivered for
      purchase and a statement that such Holder is withdrawing such Holder’s
      election to have the Note
purchased;

              

      

       

      
        	
                 
      

              	
                (7)

              	
                that, if
      the aggregate principal amount of Notes surrendered by Holders exceeds the
      Offer Amount, the Trustee shall select the Notes to be purchased on a
      pro rata basis
      (with such adjustments as may be deemed to be appropriate by the Company
      so that only Notes in denominations of $2,000, or integral multiples of
      $1,000 in excess thereof, shall be purchased);
  and

              

      

       

      
        	
                 
      

              	
                (8)

              	
                that
      Holders whose Notes were purchased only in part shall be issued new Notes
      equal in principal amount to the unpurchased portion of the Notes
      surrendered.

              

      

       

      On or before
12:00 noon on each Purchase Date, the Company shall irrevocably deposit with the
Trustee or Paying Agent in immediately available funds the aggregate purchase
price with respect to a principal amount of Notes equal to the Offer Amount,
together with accrued interest thereon, to be held for payment in accordance
with the terms of this Section 3.9.  On the Purchase Date, the Company
shall, to the extent lawful, (i) accept for payment, on a pro rata basis to the extent
necessary, an aggregate principal amount equal to the Offer Amount of Notes and
other notes (in accordance with the terms of Section 4.17 of the Indenture)
tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has
been tendered, all Notes and such other notes or portions thereof tendered, (ii)
deliver or cause the Paying Agent or depositary, as the case may be, to deliver
to the Trustee Notes so accepted and (iii) deliver to the Trustee an Officers’
Certificate stating that such Notes or portions thereof were accepted for
payment by the Company in accordance with the terms of this Section
3.9.  The Company, depositary or Paying Agent, as the case may be,
shall promptly (but in any case not later than three Business Days after the
Purchase Date) mail or deliver to each tendering Holder an amount equal to
the

      purchase price
with respect to the Notes tendered by such Holder and accepted by the Company
for purchase, and the Company shall promptly issue a new Note, and the Trustee
shall authenticate and mail or deliver such new Note, to such Holder, equal in
principal amount to any unpurchased portion of such Holder’s Notes
surrendered.  Any Note not accepted in the Asset Sale Offer shall be
promptly mailed or delivered by the Company to the Holder
thereof.  The Company shall publicly announce in a newspaper of
general circulation the results of the Asset Sale Offer on the Purchase
Date.

       

      The Asset Sale
Offer shall be made by the Company in compliance with all applicable laws,
including, without limitation, Regulation 14E of the Exchange Act and the rules
thereunder, to the extent applicable, and all other applicable federal and state
securities laws.

       

      Each purchase
pursuant to this Section 3.9 shall be made pursuant to the provisions of
Sections 3.1 through 3.6 hereof to the extent applicable.

       

      In the event the
amount of Excess Proceeds to be applied to an Asset Sale Offer would result in
the purchase of a principal amount of Notes which is not evenly divisible by
$1,000, the Trustee shall promptly refund to the Company the portion of such
Excess Proceeds that is not necessary to purchase the immediately lesser
principal amount of Notes that is so divisible.

                such
      Restricted Payment, together with the aggregate of all other Restricted
      Payments made by the Company and its Restricted Subsidiaries after the
      1996 Indenture Date is less than (x) the cumulative EBITDA of the
      Company, minus 1.75 times the cumulative Consolidated Interest Expense of
      the Company, in each case for the period (taken as one accounting period)
      from June 30, 1996, to the end of the Company’s most recently ended
      fiscal quarter for which internal financial statements are available at
      the time of such Restricted Payment, plus (y) the aggregate net
      Equity Proceeds received by the Company from the issuance or sale since
      the 1996 Indenture Date of Equity Interests of the Company or of debt
      securities of the Company that have been converted into such Equity
      Interests (other than Equity Interests or convertible debt securities sold
      to a Restricted Subsidiary of the Company and other than Disqualified
      Stock or debt securities that have been converted into Disqualified
      Stock), plus

                (1)

              	
                the payment
      of any dividend within 60 days after the date of declaration thereof,
      if at said date of declaration such payment would have complied with the
      provisions of the Indenture;

                the
      redemption, repurchase, retirement or other acquisition or retirement for
      value of any Equity Interests of the Company in exchange for, or with the

                the
      defeasance, redemption, repurchase, retirement or other acquisition or
      retirement for value of Indebtedness that is subordinated in right of
      payment to the Notes in exchange for, or with the net cash proceeds of, a

      such Indebtedness in the event of a Change of Control in accordance with
      provisions similar to the covenant set forth in Section 4.18 of the
      Indenture, provided that prior to or contemporaneously with such
      repurchase the Company has made the Change of Control Offer as provided in
      such covenant with respect to the
Notes

      and has
repurchased all Notes validly tendered for payment in connection with such
Change of Control Offer; and

       

      
        	
                 
      

              	
                (6)

              	
                additional
      payments to current or former employees or directors of the Company for
      repurchases of stock, stock options or other equity interests, provided
      that the aggregate amount of all such payments under this clause (6)
      does not exceed $0.5 million in any year and $2.0 million in the
      aggregate.

              

      

       

      The Restricted
Payments described in clauses (2), (3), (5) and (6) of the immediately
preceding paragraph shall be Restricted Payments that shall be permitted to be
taken in accordance with such paragraph but shall reduce the amount that would
otherwise be available for Restricted Payments under clause (iii) of the
first paragraph of this Section, and the Restricted Payments described in
clauses (1) and (4) of the immediately preceding paragraph shall be
Restricted Payments that shall be permitted to be taken in accordance with such
paragraph and shall not reduce the amount that would otherwise be available for
Restricted Payments under clause (iii) of the first paragraph of this
Section.

       

      If an Investment
results in the making of a Restricted Payment, the aggregate amount of all
Restricted Payments deemed to have been made as calculated under the foregoing
provision shall be reduced by the amount of any net reduction in such Investment
(resulting from the payment of interest or dividends, loan repayment, transfer
of assets or otherwise) to the extent such net reduction is not included in the
Company’s EBITDA; provided, however, that the total
amount by which the aggregate amount of all Restricted Payments may be reduced
may not exceed the lesser of (a) the cash proceeds received by the Company
and its Restricted Subsidiaries in connection with such net reduction and
(b) the initial amount of such Investment.  In addition, for the
avoidance of doubt and to avoid double counting, if an Investment results in the
making of a Restricted Payment, then the subsequent assignment, contribution,
distribution or other transfer of such Investment by the Company or any
Restricted Subsidiary of the Company to any Excluded Restricted Subsidiary or
Unrestricted Subsidiary shall not be considered a new Investment or Restricted
Payment and shall not further reduce the amount that would otherwise be
available for Restricted Payments under clause (iii) of the first paragraph of
this Section.

       

      If the aggregate
amount of all Restricted Payments calculated under the foregoing provision
includes an Investment in an Unrestricted Subsidiary or other Person that
thereafter becomes a Restricted Subsidiary, such Investment will no longer be
counted as a Restricted Payment for purposes of calculating the aggregate amount
of Restricted Payments.

       

      For the purpose
of making any Restricted Payment calculations under the Indenture:

       

      
        	
                 
      

              	
                (1)

              	
                Investments
      shall include the fair market value of the net assets of any Restricted
      Subsidiary at the time that such Restricted Subsidiary is designated an
      Unrestricted Subsidiary and shall exclude the fair market value of the net
      assets of any Unrestricted Subsidiary that is designated as a Restricted
      Subsidiary, in each case with fair market value determined by the Board of
      Directors in good faith and, for the avoidance of doubt, such inclusions
      and exclusions will not be limited by the amount of any Investment or
      aggregate Investments;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                any asset
      or property transferred to or from an Unrestricted Subsidiary shall be
      valued at fair market value at the time of such transfer, provided that,
      in each case, the fair market value of an asset or property is as
      determined by the Board of Directors in good faith and, for the avoidance
      of doubt, the fair market value (as so determined) of such asset of
      property shall be subtracted from (in the case of a transfer to an
      Unrestricted Subsidiary) or added to (in the case of a transfer from
      an

      Unrestricted
Subsidiary) the calculation under clause (iii) of the first paragraph of this
Section; and

       

      
        	
                 
      

              	
                (3)

              	
                subject to
      the foregoing, the amount of any Restricted Payment, if other than cash,
      shall be determined by the Board of Directors, whose good faith
      determination shall be conclusive.

              

      

       

      The Board of
Directors may designate a Restricted Subsidiary to be an Unrestricted Subsidiary
in compliance with Section 4.15 of the Indenture.  Upon such
designation, all outstanding Investments by the Company and its Restricted
Subsidiaries (except to the extent repaid in cash) in the Subsidiary so
designated will be deemed to be Restricted Payments made at the time of such
designation and will reduce the amount available for Restricted Payments under
the first paragraph of this covenant.  Such designation will only be
permitted if such Restricted Payment would be permitted at such time and if such
Restricted Subsidiary otherwise meets the definition of an Unrestricted
Subsidiary.

       

      (b)  Incurrence of
Indebtedness and Issuance of Preferred Stock.

       

      §4.9.  Incurrence of Indebtedness
and Issuance of Preferred Stock.  The Company
shall not, and shall not permit any of its Restricted Subsidiaries to, directly
or indirectly, create, incur, issue, assume, guaranty or otherwise become
directly or indirectly liable with respect to (collectively, “incur”) any
Indebtedness (including Acquired Debt) and the Company shall not permit any of
its Restricted Subsidiaries to issue any shares of preferred stock; provided,
however, that the Company may incur Indebtedness and may permit a Restricted
Subsidiary to incur Indebtedness if at the time of such incurrence and after
giving effect thereto the Leverage Ratio would be less than 6.5 to
1.0.

       

      The foregoing
limitations shall not apply to:

      outstanding;

      issuance by the Restricted Subsidiaries of Subsidiary
      Guarantees;

      incurrence by the Company and its Restricted Subsidiaries of the Existing
      Indebtedness;

      Obligations and/or additional Indebtedness constituting purchase money
      obligations up to an aggregate of $5.0 million at any one time
      outstanding, provided that the Liens securing such Indebtedness constitute
      Permitted Liens;

      Subsidiaries and (ii) the Restricted
  Subsidiaries;

      interest rate risk with respect to any floating rate Indebtedness that is

profits or proceeds therefrom, or assign or otherwise convey any right to
receive income therefrom, unless (a) in the case of any Lien securing any
Indebtedness that is subordinate to the Notes, the Notes are secured by a Lien
on such property, assets or proceeds that is senior in priority to such Lien and
(b) in the case of any other Lien, the Notes are equally and ratably
secured with the obligation or liability secured by such Lien.

      Subsidiaries.

              

      

       

      However, the
preceding restrictions will not apply to encumbrances or restrictions existing
under or by reason of:

      Agreement as in effect as of the date of the Indenture, and any
      amendments, modifications, restatements, renewals, increases, supplements,
      refundings, replacements or refinancing thereof, provided that such
      amendments, modifications, restatements, renewals, increases, supplements,
      refundings,

      replacements or
refinancings are no more restrictive in the aggregate with respect to such
dividend and other payment restrictions than those contained in the Credit
Agreement as in effect on the date of the Indenture;

      instrument governing Indebtedness or Capital Stock of a Person acquired by
      the Company or any of its Restricted Subsidiaries as in effect at the time
      of such acquisition (except to the extent such Indebtedness was incurred
      in connection with or in contemplation of such acquisition), which
      encumbrance or restriction is not applicable to any Person, or the
      properties or assets of any Person, other than the Person, or the property
      or assets of the Person, so acquired, provided that the EBITDA of such
      Person is not taken into account in determining whether such acquisition
      was permitted by the terms of the
Indenture;

                customary

                permitted
      Refinancing Indebtedness, provided that the restrictions contained in the
      agreements governing such Refinancing Indebtedness are no more restrictive
      in the aggregate than those contained in the agreements governing the
      Indebtedness being refinanced; or

                any
      agreement or instrument governing Indebtedness of an Excluded Restricted
      Subsidiary provided that (i) at the time such agreement or instrument
      is entered into, such Excluded Restricted Subsidiary and its Restricted
      Subsidiaries have a Leverage Ratio of less than 6.5 to 1.0 and
      (ii) neither such Excluded Restricted Subsidiary nor any of its
      Restricted Subsidiaries shall, directly or indirectly, incur any
      Indebtedness (including Acquired Debt) unless at the time of such
      incurrence and after giving effect thereto, the Leverage Ratio for such
      Excluded Restricted Subsidiary and its Restricted Subsidiaries would be
      less than 6.5 to 1.0.  For purposes of determining the Leverage
      Ratio under this clause (9) only, all references to the “Company” and
      its “Restricted Subsidiaries” or similar references in the definition of
      “Leverage Ratio” and other defined terms necessary to determine the
      Leverage Ratio shall be deemed to refer to such Excluded Restricted
      Subsidiary and its Restricted Subsidiaries,
  respectively.

              

      

       

      (e)  Transactions with
Affiliates.

       

      §4.12.  Transactions with
Affiliates.  The Company shall not, and shall not permit any of
its Restricted Subsidiaries to, sell, lease, transfer or otherwise dispose of
any of its properties or assets to, or purchase any property or assets from, or
enter into any contract, agreement, understanding, loan, advance or guarantee
with, or for the benefit of, any Affiliate (each of the foregoing, an “Affiliate
Transaction”), unless:

       

      
        
           

        

        
          26

          
            

          

        

        
           

        

      

      
        	
                 
      

              	
                (a)

              	
                such
      Affiliate Transaction is on terms that are no less favorable to the
      Company or the relevant Restricted Subsidiary than those that would have
      been obtained in a comparable transaction by the Company or such
      Restricted Subsidiary with a non-Affiliated Person;
  and

              

      

       

      
        	
                 
      

              	
                (b)

              	
                the Company
      delivers to the Trustee:

              

      

       

      
        	
                 
      

              	
                (i)

              	
                with
      respect to any Affiliate Transaction involving aggregate payments in
      excess of $5.0 million, a resolution of the Board of Directors set
      forth in an Officers’ Certificate certifying that such Affiliate
      Transaction complies with clause (a) above and such Affiliate
      Transaction is approved by a majority of the disinterested members of the
      Board of Directors; and

              

      

       

      
        	
                 
      

              	
                (ii)

              	
                with
      respect to any Affiliate Transaction involving aggregate payments in
      excess of $10.0 million, an opinion as to the fairness to the Company
      or such Restricted Subsidiary from a financial point of view issued by an
      investment banking, appraisal or accounting firm of national
      standing.

              

      

       

      The following
items shall not be deemed Affiliate Transactions and therefore, will not be
subject to the provisions of the prior paragraph:

       

      
        	
                 
      

              	
                (1)

              	
                any
      employment agreement entered into by the Company or any of its Restricted
      Subsidiaries in the ordinary course of business and consistent with the
      past practice of the Company or such Restricted
  Subsidiary;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                transactions
      between or among the Company and/or its Restricted
      Subsidiaries;

              

      

       

      
        	
                 
      

              	
                (3)

              	
                transactions
      permitted by the provisions of Section 4.8 of the Indenture;
      and

              

      

       

      
        	
                 
      

              	
                (4)

              	
                the grant
      of stock, stock options or other equity interests to employees and
      directors of the Company and any Restricted Subsidiary in accordance with
      duly adopted Company stock grant, stock option and similar
      plans.

              

      

       

      The provisions
set forth in clause (b) above shall not apply to sales of inventory by the
Company or any Restricted Subsidiary to any Affiliate in the ordinary course of
business.  The provisions of clause (b) (ii) above shall not
apply to loans or advances to the Company or any Restricted Subsidiary from, or
equity investments in the Company or any Restricted Subsidiary by, any Affiliate
to the extent permitted by the provisions of Section 4.9 of the
Indenture.

       

      

        
          
             

          

          
            27

            
              

            

          

          
             

          

        

      

       

      (f) Certain Senior Subordinated
Debt.

       

      §4.13.  Certain Senior Subordinated
Debt.  The Company
shall not incur any Indebtedness that is subordinated or junior in right of
payment to any Senior Debt of the Company and senior in any respect in right of
payment to the Notes.  The Company shall not permit any Restricted
Subsidiary to incur any Indebtedness that is subordinated or junior in right of
payment to its Senior Debt and senior in any respect in right of payment to its
Subsidiary Guarantee.

       

      (g) Additional Subsidiary
Guarantees.

       

      §4.14.  Additional Subsidiary
Guarantees.  If any entity
(other than an Excluded Restricted Subsidiary) shall become a Restricted
Subsidiary after the date of the Seventh Supplemental Indenture, then such
Restricted Subsidiary shall execute a supplemental indenture in the form of
Exhibit B attached hereto, pursuant to which it shall provide a Subsidiary
Guarantee and deliver an Opinion of Counsel with respect thereto, in accordance
with the terms of the Indenture.

       

      No Restricted
Subsidiary (including any Excluded Restricted Subsidiary) shall consolidate (or
for the avoidance of doubt, amalgamate) with or merge with or into (whether or
not such Restricted Subsidiary is the surviving Person), another Person (other
than the Company) whether or not affiliated with such Restricted Subsidiary
unless:

       

      
        	
                 
      

              	
                (1)

              	
                subject to
      the provisions of the following paragraph, the Person formed by or
      surviving any such consolidation (or amalgamation) or merger (if other
      than such Restricted Subsidiary) assumes all the obligations of such
      Restricted Subsidiary under its Subsidiary Guarantee (except in the case
      of an Excluded Restricted Subsidiary) pursuant to a supplemental indenture
      in form and substance reasonably satisfactory to the
    Trustee;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                immediately
      after giving effect to such transaction, no Default or Event of Default
      exists; and

              

      

       

      
        	
                 
      

              	
                (3)

              	
                such
      Restricted Subsidiary, or any Person formed by or surviving any such
      consolidation (or amalgamation) or merger, would be permitted to incur,
      immediately after giving effect to such transaction, at least $1.00 of
      additional Indebtedness pursuant to the test set forth in the first
      paragraph of Section 4.9 of the
Indenture.

              

      

       

      In the event
of:

       

      
        	
                 
      

              	
                (1)

              	
                a sale or
      other disposition of all of the assets of any Restricted Subsidiary, by
      way of merger, consolidation (or amalgamation) or
    otherwise;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                a sale or
      other disposition of all of the capital stock of any Restricted
      Subsidiary; or

              

      

       

      
        	
                 
      

              	
                (3)

              	
                the
      designation of a Restricted Subsidiary as an Unrestricted Subsidiary in
      accordance with the terms of Section 4.15 of the
  Indenture,

              

      

       

      then such
Restricted Subsidiary (in the event of a sale or other disposition, by way of
such a merger, consolidation (or amalgamation) or otherwise, of all of the
capital stock of such Restricted Subsidiary or in the event of the designation
of such Restricted Subsidiary as an Unrestricted Subsidiary) or the Person
acquiring the property (in the event of a sale or other disposition of all of
the assets of such Restricted

       

      
        
           

        

        
          28

          
            

          

        

        
           

        

      

      Subsidiary) will
be released and relieved of any obligations under its Subsidiary Guarantee,
provided that the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of Section 4.17 of the
Indenture.

       

      (h)  Designation of Unrestricted
Subsidiaries.

       

      §4.15.  Designation of Unrestricted
Subsidiaries.  The Board of Directors may designate any
Subsidiary (including any Restricted Subsidiary or any newly acquired or newly
formed Subsidiary) to be an Unrestricted Subsidiary so long as:

       

      
        	
                 
      

              	
                (1)

              	
                neither the
      Company nor any Restricted Subsidiary is directly or indirectly liable for
      any Indebtedness of such
Subsidiary;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                no default
      with respect to any Indebtedness of such Subsidiary would permit (upon
      notice, lapse of time or otherwise) any holder of any other Indebtedness
      of the Company or any Restricted Subsidiary to declare a default on such
      other Indebtedness or cause the payment thereof to be accelerated or
      payable prior to its stated
maturity;

              

      

       

      
        	
                 
      

              	
                (3)

              	
                any
      Investment in such Subsidiary deemed to be made as a result of designating
      such Subsidiary an Unrestricted Subsidiary will not violate the provisions
      of Section 4.8 of the Indenture;

              

      

       

      
        	
                 
      

              	
                (4)

              	
                neither the
      Company nor any Restricted Subsidiary has a contract, agreement,
      arrangement, understanding or obligation of any kind, whether written or
      oral, with such Subsidiary other than (A) those that might be
      obtained at the time from Persons who are not Affiliates of the Company or
      (B) administrative, tax sharing and other ordinary course contracts,
      agreements, arrangements and understandings or obligations entered into in
      the ordinary course of business;
and

              

      

       

      
        	
                 
      

              	
                (5)

              	
                neither the
      Company nor any Restricted Subsidiary has any obligation to subscribe for
      additional shares of Capital Stock or other Equity Interests in such
      Subsidiary, or to maintain or preserve such Subsidiary’s financial
      condition or to cause such Subsidiary to achieve certain levels of
      operating results other than as permitted under Section 4.8 of the
      Indenture.

              

      

       

      Notwithstanding
the foregoing, the Company may not designate as an Unrestricted Subsidiary any
Subsidiary which, on the 1999 Indenture Date, was a Significant Subsidiary, and
may not sell, transfer or otherwise dispose of any properties or assets of any
such Significant Subsidiary to an Unrestricted Subsidiary, other than in the
ordinary course of business, in each case other than Iron Mountain Global, Inc.
and its Subsidiaries (including without limitation Iron Mountain Europe Limited
and its Subsidiaries). For the avoidance of doubt, the provisions of this
Section 4.15 shall not limit or restrict the ability of any Restricted
Subsidiary to sell, transfer or otherwise dispose of any properties or assets to
any other Subsidiary, including any Unrestricted Subsidiary, to the extent such
sale, transfer or other disposition is permitted by the provisions of the
Indenture described under Section 4.12 or Section 4.17.

       

      The Board of
Directors may designate any Unrestricted Subsidiary as a Restricted Subsidiary;
provided that such designation will be deemed to be an incurrence of
Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such
Unrestricted Subsidiary and such designation will only be permitted
if:

       

      
        
           

        

        
          29

          
            

          

        

        
           

        

      

      
        	
                 
      

              	
                (1)

              	
                such
      Indebtedness is permitted under Section 4.9 of the Indenture;
      and

              

      

       

      
        	
                 
      

              	
                (2)

              	
                no Default
      or Event of Default would occur as a result of such
      designation.

              

      

       

      (i)    Limitation on Sale and Leaseback
Transactions.

       

      §4.16.  Limitation on Sale and
Leaseback Transactions.  The Company will not, and will not
permit any Restricted Subsidiary to, enter into any Sale and Leaseback
Transaction unless:

       

      
        	
                 
      

              	
                (1)

              	
                the
      consideration received in such Sale and Leaseback Transaction is at least
      equal to the fair market value of the property sold, as determined by a
      resolution of the Board of Directors;
and

              

      

       

      
        	
                 
      

              	
                (2)

              	
                the Company
      or such Restricted Subsidiary could incur the Attributable Indebtedness in
      respect of such Sale and Leaseback Transaction in compliance with Section
      4.9 of the Indenture.

              

      

       

      (j)    Asset Sales.

       

      §4.17.  Asset
Sales.  The Company shall not, and shall not permit any of its
Restricted Subsidiaries to:

       

      
        	
                 
      

              	
                (1)

              	
                sell,
      lease, convey or otherwise dispose of any assets (including by way of a
      Sale and Leaseback Transaction, but excluding a Qualifying Sale and
      Leaseback Transaction) other than sales of inventory in the ordinary
      course of business (provided that the sale, lease, conveyance or other
      disposition of all or substantially all of the assets of the Company will
      be governed by the provisions of Section 4.18 of the Indenture and/or the
      provisions of Section 5.1 of the Indenture and not by the provisions of
      this Section 4.17); or

              

      

       

      
        	
                 
      

              	
                (2)

              	
                issue or
      sell Equity Interests of any of its Restricted
  Subsidiaries

              

      

       

      that in the case
of either clause (1) or (2) above, whether in a single transaction or
a series of related transactions:

       

      
        	
                 
      

              	
                (i)

              	
                have a fair
      market value in excess of $2.0 million;
or

              

      

       

      
        	
                 
      

              	
                (ii)

              	
                result in
      Net Proceeds in excess of $2.0 million (each of the foregoing, an
      “Asset Sale”) unless (x) the Company (or the Restricted Subsidiary,
      as the case may be) receives consideration at the time of such Asset Sale
      at least equal to the fair market value (evidenced by an Officers’
      Certificate delivered to the Trustee, and for Asset Sales having a fair
      market value or resulting in Net Proceeds in excess of $10.0 million,
      evidenced by a resolution of the Board of Directors set forth in an
      Officers’ Certificate delivered to the Trustee) of the assets sold or
      otherwise disposed of and (y) at least 75% of the consideration
      therefor received by the Company or such Restricted Subsidiary is in the
      form of cash or like-kind assets (in each case as determined in good faith
      by the Company, evidenced by a resolution of the Board of Directors and
      certified by an Officers’ Certificate delivered to the
      Trustee);

              

      

       

      provided, however, that the amount
of:

       

      
        
           

        

        
          30

          
            

          

        

        
           

        

      

      
        	
                 
      

              	
                (A)

              	
                any
      liabilities (as shown on the Company’s or such Restricted Subsidiary’s
      most recent balance sheet or in the notes thereto) of the Company or such
      Restricted Subsidiary (other than liabilities that are by their terms
      subordinated to the Notes or any Subsidiary Guarantee) that are assumed by
      the transferee of any such assets;
and

              

      

       

      
        	
                 
      

              	
                (B)

              	
                any notes
      or other obligations received by the Company or such Restricted Subsidiary
      from such transferee that are immediately converted by the Company or such
      Restricted Subsidiary into cash (to the extent of the cash received) or
      Cash Equivalents, 

              

      

       

      shall be deemed
to be cash for purposes of this provision; and provided, further, that the 75%
limitation referred to in the foregoing clause (ii) (y) shall not
apply to any Asset Sale in which the cash portion of the consideration received
therefrom is equal to or greater than what the after-tax proceeds would have
been had such Asset Sale complied with the aforementioned 75%
limitation.  For the avoidance of doubt, a disposition that
constitutes a Restricted Payment will be governed by the provisions of Section
4.8 and not by this Section 4.17.

       

      A transfer of
assets or issuance of Equity Interests by the Company to a Wholly Owned
Restricted Subsidiary or by a Wholly Owned Restricted Subsidiary to the Company
or to another Wholly Owned Restricted Subsidiary will not be deemed to be an
Asset Sale.

       

      Within
360 days of any Asset Sale, the Company may, at its option, apply an amount
equal to the Net Proceeds from such Asset Sale either:

       

      
        	
                 
      

              	
                (1)

              	
                to
      permanently reduce Senior Debt; or

              

      

       

      
        	
                 
      

              	
                (2)

              	
                to an
      investment in a Restricted Subsidiary or in another business or capital
      expenditure or other long-term/tangible assets, in each case, in the same
      line of business as the Company or any of its Restricted Subsidiaries was
      engaged in on the date of the Seventh Supplemental Indenture or in
      businesses similar or reasonably related
  thereto.

              

      

       

      Pending the final
application of any such Net Proceeds, the Company may temporarily reduce Senior
Bank Debt or otherwise invest such Net Proceeds in any manner that is not
prohibited by the Indenture.  Any Net Proceeds from such Asset Sale
that are not applied or invested as provided in the first sentence of this
paragraph will be deemed to constitute “Excess Proceeds.”  When the
aggregate amount of Excess Proceeds exceeds $10.0 million, the Company
shall make an offer to all Holders of the Notes, all holders of the 71⁄2% Notes,
the 85⁄8% Notes, the 71⁄4% Notes, the 73⁄4% Notes, the 65⁄8% Notes,  the 83⁄4%
Notes, the 8% Notes and the 63⁄4% Notes and the holders of any future Indebtedness
ranking pari passu with
the Notes, which Indebtedness contains similar provisions requiring the Company
to repurchase such Indebtedness (an “Asset Sale Offer”), to purchase the maximum
principal amount of Notes and such other Indebtedness that may be purchased out
of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of
the principal amount thereof plus accrued and unpaid interest, if any, to the
date of purchase, in accordance with the procedures set forth in the
Indenture.  To the extent that the aggregate amount of Notes and other
pari passu Indebtedness
(the 71⁄2% Notes, the 85⁄8% Notes, the 71⁄4% Notes, the 73⁄4% Notes, the 65⁄8%
Notes,  the 83⁄4% Notes, the 8% Notes and the 63⁄4% Notes) tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company
may use any remaining Excess Proceeds for general corporate
purposes.  If the aggregate principal amount of Notes and such other
Indebtedness surrendered by Holders thereof exceeds the amount of Excess
Proceeds, the

       

      
        
           

        

        
          31

          
            

          

        

        
           

        

      

      Trustee shall
select the Notes and such other Indebtedness to be purchased on a pro rata
basis. Upon completion of such offer to purchase, the amount of Excess Proceeds
shall be reset at zero.

       

      The Company shall
comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder to the extent those laws and
regulations are applicable in connection with each repurchase of Notes pursuant
to an Asset Sale Offer.  To the extent that the provisions of any
securities laws or regulations conflict with the provisions of this Section
4.17, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under the
Asset Sale provisions of the Indenture by virtue of such conflict.

       

      An Asset Sale
Offer shall be made pursuant to the provisions of Section 3.9
hereof.  No later than the date which is five Business Days after the
date on which the aggregate amount of Excess Proceeds exceeds $10.0 million, the
Company shall notify the Trustee of such Asset Sale Offer and provide the
Trustee with an Officers’ Certificate setting forth the calculations used in
determining the amount of Net Proceeds to be applied to the purchase of
Notes.  The Company shall commence or cause to be commenced the Asset
Sale Offer on a date no later than 15 Business Days after such notice (the
“Commencement Date”).

       

      (k)  Change of Control Offer.

       

      §
4.18.  Change of Control
Offer.

       

      (a)  Upon
the occurrence of a Change of Control, each Holder of Notes shall have the right
to require the Company to repurchase all or any part (equal to $2,000 or an
integral multiple of $1,000 in excess thereof) of such Holder’s Notes pursuant
to the offer described below (the “Change of Control Offer”) at an offer price
in cash equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest to but excluding the date of repurchase (the “Change of Control
Payment”).

       

      Within 30
calendar days following any Change of Control, the Company shall mail a notice
to each Holder, with a copy to the Trustee, stating:

       

      
        	
                 
      

              	
                (1)

              	
                that the
      Change of Control Offer is being made pursuant to this Section 4.18 and
      that all Notes tendered shall be accepted for
  payment;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                the
      purchase price and the purchase date, which shall be no earlier than 30
      calendar days nor later than 60 calendar days from the date such notice is
      mailed (the “Change of Control Payment
Date”);

              

      

       

      
        	
                 
      

              	
                (3)

              	
                that any
      Note not tendered shall continue to accrue
  interest;

              

      

       

      
        	
                 
      

              	
                (4)

              	
                that,
      unless the Company defaults in the payment of the Change of Control
      Payment, all Notes accepted for payment pursuant to the Change of Control
      Offer shall cease to accrue interest on and after the Change of Control
      Payment Date;

              

      

       

      
        	
                 
      

              	
                (5)

              	
                that
      Holders electing to have any Notes purchased pursuant to a Change of
      Control Offer shall be required to surrender the Notes, with the form
      entitled “Option of Holder to Elect Purchase” on the reverse of the Notes
      completed, to the Paying Agent at the address specified in such notice
      prior to the close of business on the fifth Business Day preceding the
      Change of Control Payment Date;

              

      

       

      
        
           

        

        
          32

          
            

          

        

        
           

        

      

      
        	
                 
      

              	
                (6)

              	
                that
      Holders will be entitled to withdraw their election if the Paying Agent
      receives, not later than the close of business on the second Business Day
      preceding the Change of Control Payment Date, facsimile transmission or
      letter setting forth the name of the Holder, the principal amount of Notes
      delivered for purchase, and a statement that such Holder is withdrawing
      its election to have such Notes purchased;
and

              

      

       

      
        	
                 
      

              	
                (7)

              	
                that
      Holders whose Notes are being purchased only in part will be issued new
      Notes equal in principal amount to the unpurchased portion of the Notes
      surrendered, which unpurchased portion must be equal to $2,000 in
      principal amount or an integral multiple of $1,00 in excess
      thereof.

              

      

       

      The Company shall
comply with the requirements of Rule 14e-1 under the Exchange Act and any
other securities laws and regulations thereunder, to the extent such laws and
regulations are applicable to the repurchase of the Notes in connection with a
Change of Control.  To the extent that the provisions of any
securities laws or regulations conflict with this Section 4.18, the Company
shall comply with the applicable securities laws and regulations and shall not
be deemed to have breached its obligations under the Change of Control
provisions of the Indenture or the Seventh Supplemental Indenture by virtue of
such conflict.

       

      (b)  On
the Change of Control Payment Date, the Company shall, to the extent
lawful:

       

      
        	
                 
      

              	
                (1)

              	
                accept for
      payment Notes or portions thereof tendered pursuant to the Change of
      Control Offer;

              

      

       

      
        	
                 
      

              	
                (2)

              	
                deposit
      with the Paying Agent an amount equal to the Change of Control Payment in
      respect of all Notes or portions thereof so tendered;
  and

              

      

       

      
        	
                 
      

              	
                (3)

              	
                deliver or
      cause to be delivered to the Trustee the Notes so accepted together with
      an Officers’ Certificate stating the Notes or portions thereof tendered to
      the Company.

              

      

       

      The Paying Agent
shall promptly mail to each Holder of Notes so accepted the Change of Control
Payment for such Notes, and the Trustee shall promptly authenticate and mail to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that each such new Note shall be in a
principal amount of $2,000 or an integral multiple of $1,000 in excess
thereof.

       

      The Company shall
not be required to make a Change of Control Offer upon a Change of Control if a
third party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in this Section 4.18
applicable to a Change of Control Offer made by the Company and purchases all
Notes properly tendered and not withdrawn under the Change of Control
Offer.

      §
4.19.  Changes in Covenants When
Notes Rated Investment Grade.

       

      If on any date
following the date of this Seventh Supplemental Indenture:

following:

       

      
        
           

        

        
          34

          
            

          

        

        
           

        

      

      §
4.2.  Reports.

       

      Whether or not
required by the rules and regulations of the Commission, so long as any Notes
are outstanding, the Company will furnish to the Holders of Notes:

       

      
        	
                 
      

              	
                (1)

              	
                all
      quarterly and annual financial information that would be required to be
      contained in a filing with the Commission on Forms 10-Q and 10-K if the
      Company were required to file such Forms, including a “Management’s
      Discussion and Analysis of Financial Condition and Results of Operations”
      and, with respect to the annual information only, a report thereon by the
      Company’s certified independent accountants;
and

              

      

       

      
        	
                 
      

              	
                (2)

              	
                all
      financial information that would be required to be included in a
      Form 8-K filed with the Commission if the Company were required to
      file such reports.

              

      

       

      In addition,
whether or not required by the rules and regulations of the Commission, the
Company will file a copy of all such information and reports with the Commission
for public availability (unless the Commission will not accept such a filing)
and make such information available to investors who request it in
writing.

       

      Notwithstanding
the foregoing, if at any time the Notes are guaranteed by any direct or indirect
parent company of the Company, the indenture will permit the Company to satisfy
its obligations under this covenant with respect to financial information
relating to the Company by furnishing financial information relating to such
direct or indirect parent company; provided, however, that the same is
accompanied by consolidating information that explains in reasonable detail the
differences between the information relating to such direct or indirect parent
company and any of its Subsidiaries other than the Company and its Subsidiaries,
on the one hand, and the information relating to the Company, the Guarantors and
the other Subsidiaries of the Company on a standalone basis, on the other
hand.

       

      Section
2.11.  Events of
Default.

       

      Section 6.1 of
the Indenture is amended with regard to this Seventh Supplemental Indenture and
the Notes issued hereunder by deleting the $10.0 million threshold in Sections
6.1(e)(ii) and 6.1(f) and substituting in lieu thereof the threshold of $50.0
million.

       

      Section
2.12.  Amend, Restate and Replace
Provision Regarding Personal Liability.

       

      With respect to
the Notes issued under this Seventh Supplemental Indenture, Section 10.8 of the
Indenture is amended, restated and replaced in its entirety by the
following:

       

      §
10.8.  No
Personal Liability of Directors, Officers, Employees and
Stockholders.

       

      No director, officer, employee, incorporator or
stockholder of the Company or any Restricted Subsidiary, as such, shall have any
liability for any obligations of the Company or any Restricted Subsidiary under
the Notes, the Subsidiary Guarantees or the Indenture or for any claim based on,
in respect of, or by reason of, such obligations or their creation. Each Holder
of Notes by accepting a Note and the Subsidiary Guarantees waives and releases
all such liability. The waiver and release are part of the consideration for
issuance of the Notes and the Subsidiary Guarantees.

      This Security is
a Global Security within the meaning of the Indenture hereinafter referred to
and is registered in the name of the Depository or a nominee of the Depository.
This Security is exchangeable for Securities registered in the name of a Person
other than the Depository or its nominee only in the limited circumstances
described in the Indenture, and may not be transferred except as a whole by the
Depository to a nominee of the Depository, by a nominee of the Depository to the
Depository or another nominee of the Depository or by the Depository or any such
nominee to a successor Depository or a nominee of such a successor
Depository.

       

      Unless and until
it is exchanged in whole or in part for Notes in definitive form, this Note may
not be transferred except as a whole by the Depository to a nominee of the
Depository or by a nominee of the Depository to the Depository or another
nominee of the Depository or by the Depository or any such nominee to a
successor Depository or a nominee of such successor Depository. Unless this
certificate is presented by an authorized representative of The Depository Trust
Company (55 Water Street, New York, New York) ("DTC"), to the issuer or its
agent for registration of transfer, exchange or payment, and any certificate
issued is registered in the name of Cede & Co. or such other name as may be
requested by an authorized representative of DTC (and any payment is made to
Cede & Co. or such other entity as may be requested by an authorized
representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
hereof, Cede & Co., has an interest herein.

       

      Capitalized terms
used herein shall have the meanings assigned to them in the Indenture referred
to below unless otherwise indicated.

       

      1.           Interest.  Iron
Mountain Incorporated, a Delaware corporation (the “Company”) promises to pay
interest on the principal amount of this Note at 8% per annum from June 5, 2008
until June 15, 2020.  The Company shall pay interest, semi-annually in
arrears on June 15 and December of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each an “Interest Payment
Date”).  Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the
date of issuance; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a record date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided,
further, that the first
Interest Payment Date shall be December 15, 2008.  The Company shall
pay interest (including post-petition interest to the extent allowed in any
proceeding under any Bankruptcy Law) on overdue principal from time to time on
demand at a rate equal to the per annum rate on the Notes then in effect; it
shall pay interest (including post-petition interest to the extent allowed in
any proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful.  Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

       

      2.           Method of
Payment.  The Company will pay principal, premium, if any, and
interest on the Notes in money of the United States that at the time of payment
is legal tender for payment of public and private debts. The Company, however,
may pay principal, premium, if any, and interest by check payable in such money.
It may mail an interest check to a Holder's registered address.

       

      3.           Paying
Agent and Registrar.  Initially, The Bank of New York Trust
Company, N.A., the Trustee under the Indenture, will act as paying agent,
registrar and service agent.  The Notes may be presented for
registration of transfer and exchange at the offices of the
registrar.  The Company may change any paying agent, service agent or
registrar without notice to any Holder.  The Company or any of its
Subsidiaries may act in any such capacity.

       

      
        
          
          

        

        
          A-2

          
            

          

        

        
          
          

        

      

      4.           Indenture.  The
Company issued the Notes under an Indenture dated as of December 30, 2002 (the
"Base Indenture") as supplemented by a Seventh Supplemental Indenture dated as
of June 5, 2008 (the "Seventh Supplemental Indenture " and, together with the
Base Indenture, the "Indenture") among the Company, the Guarantors and the
Trustee. The terms of the Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended (15 U.S. Code Sections 77aaa-77bbbb). The Notes are subject to all such
terms, and Holders are referred to the Indenture and such Act for a statement of
such terms. To the extent any provision of this Note conflicts with the express
provisions of the Indenture, the provisions of the Indenture shall govern and be
controlling. The Notes issued under the Indenture are subordinated unsecured
obligations of the Company limited to $300,000,000 in aggregate principal
amount.

      2014

              	
                102.667%

              
	
                June 15,

                101.333%

              
	
                June 16,
      2013 and thereafter

              	
                100.000%

              
	 
      	 
      

      

      

      Notwithstanding
the foregoing, at any time prior to June 15, 2011, the Company may on any one or
more occasions redeem the Notes at a redemption price of 108% of the principal
amount thereof, plus accrued and unpaid interest, and Liquidated Damages if any,
to the redemption date, with the net cash proceeds of one or more Qualified
Equity Offerings; provided that: (i) at least $ 195 million in the aggregate
principal amount of the Notes (including any Additional Notes) issued under the
Indenture remains outstanding immediately after the occurrence of such
redemption (excluding Notes held by the Company and the Company’s Subsidiaries);
and (ii) the redemption must occur within six months of the date of the closing
of any such Qualified Equity Offering.

       

      6.           Notice of
Redemption.  Notice of redemption will be mailed at least 10
days but not more than 60 days before the redemption date to each Holder of the
Notes to be redeemed at such Holder's address of record. The Notes in
denominations larger than $2,000 may be redeemed in part but only in integral
multiples of $1,000 in excess thereof, unless all the Notes held by a Holder are
to be redeemed. In the event of a redemption of less than all of the Notes, the
Notes will be chosen for redemption by the Trustee in accordance with the
Indenture. On and after the redemption date, interest ceases to accrue on the
Notes or portions of them called for redemption.

       

      If this Note is
redeemed subsequent to a Record Date with respect to any Interest Payment Date
specified above and on or prior to such Interest Payment Date, then any accrued
interest will be paid to the Person in whose name this Note is registered at the
close of business on such Record Date.

       

      
        
          
          

        

        
          A-3

          
            

          

        

        
          
          

        

      

      7.           Mandatory
Redemption.  Except as set forth in paragraph 8 below, the
Company shall not be required to repurchase or to make mandatory redemption
payments with respect to the Notes.  There are no sinking fund
payments with respect to the Notes.

       

      8.           Repurchase
at Option of Holder.  This Note is subject to purchase at the
option of the Holder upon the circumstances set forth in Sections 3.9, 4.17 and
4.18 of the Indenture.

       

      9.           Subordination.
The payment of the principal of, interest on or any other amounts due on the
Notes is subordinated in right of payment to all existing and future Senior Debt
of the Company, as described in the Indenture. Each Holder, by accepting a Note,
agrees to such subordination and authorizes and directs the Trustee on its
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided and appoints the Trustee as its attorney-in-fact for
such purpose.

       

      10.           Denominations,
Transfer, Exchange.  The Notes are in registered form without
coupons in minimum denominations of $2,000 and integral multiples of $1,000 in
excess thereof. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Note or portion of a Note selected for
redemption, except for the unredeemed portion of any Note being redeemed in
part. Also, the Company need not exchange or register the transfer of any Notes
for a period of 15 days before a selection of Notes to be redeemed or during the
period between a record date and the corresponding Interest Payment
Date.

      

      11.           Persons
Deemed Owners.  The registered Holder of a Note may be treated
as its owner for all purposes.

       

      12.           Amendment,
Supplement and Waiver. Subject to certain exceptions, the Indenture with
respect to the Notes or the Notes may be amended or supplemented with the
written consent of the Holders of a majority in principal amount of the Notes
and any existing default or compliance with any provision of the Indenture with
respect to the Notes or the Notes may be waived with the consent of the Holders
of a majority in principal amount of the Notes (including, in each case,
Additional Notes, if any). Without the consent of any Holder of the Notes, the
Indenture with respect to the Notes or the Notes may be amended or supplemented
to, in addition to other events more fully described in the Indenture, cure any
ambiguity, defect or inconsistency, provide for uncertificated Notes in addition
to or in place of certificated Notes, provide for the assumption of the
Company's obligations to Holders of the Notes in the case of a merger or
consolidation, make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights under the Indenture of any such Holder, or comply with requirements of
the SEC in order to effect or maintain the qualification of the Indenture under
the TIA.

       

      13.           Defaults
and remedies.  An Event of Default with respect to the Notes
occurs upon the occurrence of any of the following events: the default for 30
days in the payment when due of interest on the Notes (whether or not prohibited
by the subordination provisions of the Indenture); the default in payment when
due of the principal of or premium, if any, on the Notes (whether or not
prohibited by the subordination provisions of the Indenture); the failure by the
Company to comply with Section 4.18 of the Indenture; the failure by the Company
or any Guarantor for 60 days after written notice from the Trustee or Holders of
not less than 25% of the aggregate principal amount of the Notes 

       

      
        
          
          

        

        
          A-4

          
            

          

        

        
          
          

        

      

      (including
Additional Notes, if any) outstanding to comply with any of its other agreements
in the Indenture, Notes or the Subsidiary Guarantees; the default under any
mortgage, indenture or instrument under which there may be issued or by which
there may be secured or evidenced any Indebtedness for money borrowed by the
Company or any of its Restricted Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Restricted Subsidiaries) whether such
Indebtedness or guarantee exists on the date of the Indenture or is created
thereafter, if: (i) such default results in the acceleration of such
Indebtedness prior to its express maturity or shall constitute a default in the
payment of such Indebtedness at final maturity of such Indebtedness and (ii) the
principal amount of any such Indebtedness that has been accelerated or not paid
at maturity, when added to the aggregate principal amount of all other such
Indebtedness that has been accelerated or not paid at maturity, exceeds $10.0
million; the failure by the Company or any of its Restricted Subsidiaries to pay
final judgments aggregating in excess of $10.0 million, which judgments remain
unpaid, undischarged or unstayed for a period of 60 days; certain events of
bankruptcy or insolvency with respect to the Company or any of its Restricted
Subsidiaries that is a Significant Subsidiary; or except as permitted by the
Indenture or the Subsidiary Guarantees, any Subsidiary Guarantee issued by a
Restricted Subsidiary shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect, or any Restricted Subsidiary or any Person acting on behalf of any
Restricted Subsidiary shall deny or disaffirm in writing its obligations under
its Subsidiary Guarantee.

       

      If any Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes (including Additional Notes, if
any) may declare all the Notes to be due and payable immediately; provided,
however, that if any Obligation with respect to Senior Bank Debt is outstanding
pursuant to the Credit Agreement upon a declaration of acceleration of the
Notes, the principal, premium, if any, and interest on the Notes will not be
payable until the earlier of: (1)the day which is five business days after
written notice of acceleration is received by the Company and the Credit Agent
or (2) the date of acceleration of the Indebtedness under the Credit Agreement.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency with respect to the Company or any
Restricted Subsidiary that is a Significant Subsidiary, the principal of, and
premium, if any, and any accrued and unpaid interest on all outstanding Notes
will become due and payable without further action or notice. In the event of a
declaration of acceleration of the Notes because an Event of Default has
occurred and is continuing as a result of the acceleration of any Indebtedness
described in Section 6.1(e) of the Indenture, the declaration of acceleration of
the Notes shall be automatically annulled if the holders of any Indebtedness
described in such section have rescinded the declaration of acceleration in
respect of such Indebtedness within 30 days from the date of such declaration
and if: (1) the annulment of the acceleration of the Notes would not conflict
with any judgment or decree of a competent jurisdiction and (2) all existing
Events of Default, except non-payment of principal or interest on the Notes that
became due solely because of the acceleration of the Notes, have been cured or
waived.

      

      Subject to
certain limitations, Holders of a majority in principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of the Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest. The Company is required to deliver to the Trustee annually
a statement regarding compliance with the Indenture, and the Company is
required, upon becoming aware of any Default or Event of Default, to deliver to
the Trustee a statement specifying such Default or Event of Default and what
action the Company is taking or proposes to take thereto.

      

       

      14.           Subsidiary
Guarantees.  Payment of principal of, premium, if any, and
interest (including interest on overdue principal, if any, and interest, if
lawful) on the Notes is guaranteed on an unsecured, senior subordinated basis by
the Guarantors pursuant to Article XII of the Indenture.

       

       

      
        
          
          

        

        
          A-5

          
            

          

        

        
          
          

        

      

      15.           Trustee
Dealings with Company.  The Trustee, in its individual or any
other capacity, may make loans to, accept deposits from, and perform services
for the Company or its Affiliates, and may otherwise deal with the Company or
its Affiliates, as if it were not the Trustee.

       

      16.           No
Recourse Against Others.  No past, present or future director,
officer, employee, incorporator or stockholder, as such, of the Company or any
Guarantor shall have any liability for any obligations of the Company or any
Guarantor under the Notes, the Subsidiary Guarantees or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation.  Each Holder by accepting a Note and the related Subsidiary
Guarantees waives and releases all such liability.  The waiver and
release are part of the consideration for the issuance of the
Notes.

       

      17.           Authentication.  This
Note shall not be valid until authenticated by the manual signature of the
Trustee or an authenticating agent.

       

      18.           Abbreviations.  Customary
abbreviations may be used in the name of a Holder or an assignee, such
as:  TEN COM (= tenants in common), TEN ENT (= tenants by the
entireties), JT TEN (= joint tenants with right of survivorship and not as
tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors
Act).

       

      19.           CUSIP
Numbers. Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Company has caused CUSIP numbers
to be printed on the Notes and the Trustee may use CUSIP numbers in notices of
redemption as a convenience to Holders. No representation is made as to the
accuracy of such numbers either as printed on the Notes or as contained in any
notice of redemption and reliance may be placed only on the other identification
numbers placed thereon.

       

      The Company shall
furnish to any Holder upon written request and without charge a copy of the
Indenture.  Requests may be made to:

      FORM OF
SUPPLEMENTAL INDENTURE

       

      TO BE DELIVERED
BY FUTURE GUARANTORS

       

      Supplemental
Indenture (this “Supplemental
Indenture”), dated as of ________________, 20__, among _______________
(the “Guaranteeing
Subsidiary”), a subsidiary of Iron Mountain Incorporated (or its
successor), a Delaware corporation (the “Company”),  and The
Bank of New York Trust Company, N.A., a national banking association, as trustee
under the Indenture referred to below (the “Trustee”).

       

      W I T N E S S E T
H

       

      WHEREAS, the
Company has heretofore executed and delivered to the Trustee an indenture, dated
as of December 30, 2002, as supplemented by the Seventh Supplemental Indenture,
dated as of June 5, 2008 (the indenture, as so supplemented, the “Indenture”) providing for the
issuance of an aggregate principal amount of up to $300,000,000 of 8% Senior
Subordinated Notes due 2020 (the “Notes”);

       

      WHEREAS, the
Indenture provides that under certain circumstances the Guaranteeing Subsidiary
shall execute and deliver to the Trustee a supplemental indenture pursuant to
which the Guaranteeing Subsidiary shall unconditionally guarantee all of the
Company’s obligations under the Notes and the Indenture on the terms and
conditions set forth herein (the “Note Guarantee”);
and

       

      WHEREAS, pursuant
to Section 9.1 of the Indenture, the Trustee is authorized to execute and
deliver this Supplemental Indenture.

       

      NOW THEREFORE, in
consideration of the foregoing and for other good and valuable consideration,
the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the
Trustee mutually covenant and agree for the equal and ratable benefit of the
Holders of the Notes as follows:

       

      1.           Capitalized
Terms.  Capitalized
terms used herein without definition shall have the meanings assigned to them in
the Indenture.

       

      2.           Agreement
to Guarantee.  The Guaranteeing Subsidiary hereby agrees that
its obligations to the Holder and the Trustee pursuant to this Subsidiary
Guarantee shall be as expressly set forth in Article XII of the Indenture and in
such other provisions of the Indenture as are applicable to the Guarantors
(including, without limitation, Article XIII of the Indenture), and reference is
made to the Indenture for the precise terms of this Supplemental
Indenture.  The terms of Article XII of the Indenture and such other
provisions of the Indenture (including, without limitation, Article XIII of the
Indenture) as are applicable to the Guarantors are incorporated herein by
reference.

       

      3.           Execution
and Delivery of Subsidiary Guarantees.

       

         
(a)           If an
Officer whose signature is on this Supplemental Indenture no longer holds that
office at the time the Trustee authenticates the Note, the Subsidiary Guarantee
shall be valid nevertheless.

       

         
(b)           The
delivery of any Note by the Trustee, after the authentication thereof under the
Indenture, shall constitute due delivery of the Subsidiary Guarantee set forth
in this Supplemental Indenture on behalf of the Guaranteeing
Subsidiary.

       

      
        
          
          

        

        
          B-1

          
            

          

        

        
          
          

        

      

      4.           No
Recourse Against Others.  No past, present or future director,
officer, employee, incorporator or stockholder of the Guaranteeing Subsidiary,
as such, shall have any liability for any obligations of the Company or any
Guarantor (including the Guaranteeing Subsidiary) under the Notes, any
Subsidiary Guarantee, the Indenture or this Supplemental Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their
creation.  Each Holder of the Notes by accepting a Note waives and
releases all such liability.  The waiver and release are part of the
consideration for issuance of the Notes.

       

      5.           New York
Law to Govern.  THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT GIVING
EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

       

      6.           Counterparts.  The
parties may sign any number of copies of this Supplemental
Indenture.  Each signed copy shall be an original, but all of them
together represent the same agreement.

       

      7.           Effect of
Headings.  The Section headings herein are for convenience only
and shall not affect the construction hereof.

       

      8.           The
Trustee.  The Trustee shall not be responsible in any manner
whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which
recitals are made solely by the Guaranteeing Subsidiary and the
Company.

       

       

       

       

       

       

       

       

       

       

       

       

      
        
          
          

           

        

        
          B-2

          
            

          

        

        
           

        

      

      IN WITNESS
WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly
