                        INDENTURE dated as of September 9, 2004, among SECURUS
                  TECHNOLOGIES, INC., a Delaware corporation (the "Company"),
                  the Subsidiary Guarantors listed on Schedule I attached hereto
                  and THE BANK OF NEW YORK TRUST COMPANY, N.A., a national
                  banking association (the "Trustee").

            Each party agrees as follows for the benefit of the other parties
and for the equal and ratable benefit of the Holders of the Company's Initial
Securities, Exchange Securities and Private Exchange Securities (each as defined
in the Rule 144A/Regulation S Appendix hereto and collectively, the
"Securities").

                                   ARTICLE 1

                   Definitions and Incorporation by Reference

            SECTION 1.01. Definitions.

            "Additional Assets" means (1) any property, plant or equipment used
in a Related Business; (2) the Capital Stock of a Person that becomes a
Restricted Subsidiary as a result of the acquisition of such Capital Stock by
the Company or another Restricted Subsidiary; or (3) Capital Stock constituting
a minority interest in any Person that at such time is a Restricted Subsidiary;
provided, however, that any such Restricted Subsidiary described in clause (2)
or (3) above is primarily engaged in a Related Business.

            "Additional Securities" means Securities issued under this Indenture
after the Issue Date and in compliance with Section 2.13 and 4.03, it being
understood that any Securities issued in exchange for or replacement of any
Initial Security issued on the Issue Date shall not be an Additional Security,
including any such Securities issued pursuant to a Registration Rights
Agreement.

            "Adjusted Treasury Rate" means, with respect to any redemption date,
(i) the yield, under the heading which represents the average for the
immediately preceding week, appearing in the most recently published statistical
release designated "H.15(519)" or any successor publication which is published
weekly by the Board of Governors of the Federal Reserve System and which
establishes yields on actively traded United States Treasury securities adjusted
to constant maturity under the caption "Treasury Constant Maturities", for the
maturity corresponding to the Comparable Treasury Issue (if no maturity is
within three months before or after September 1, 2008, yields for the two
published maturities most closely corresponding to the Comparable Treasury Issue
shall be determined and the Adjusted Treasury Rate shall be interpolated or
extrapolated from such yields on a straight line basis, rounding to the nearest
month) or (ii) if such release (or any successor release) is not published
during the week preceding the calculation date or does not contain such yields,
the rate per year equal to the semi-annual equivalent yield to maturity of the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such redemption date, in each case
calculated on the third Business Day immediately preceding the redemption date,
plus, in either case, .50%.

                                                                               2

            "Affiliate" of any specified Person means any other Person, directly
or indirectly, controlling or controlled by or under direct or indirect common
control with such specified Person. For the purposes of this definition,
"control" when used with respect to any Person means the power to direct the
management and policies of such Person, directly or indirectly, whether through
the ownership of voting securities, by contract or otherwise; and the terms
"controlling" and "controlled" have meanings correlative to the foregoing. For
purposes of Sections 4.04, 4.06 and 4.07 only, "Affiliate" shall also mean any
beneficial owner of Capital Stock representing 10% or more of the total voting
power of the Voting Stock (on a fully diluted basis) of the Company or of rights
or warrants to purchase such Capital Stock (whether or not currently
exercisable) and any Person who would be an Affiliate of any such beneficial
owner pursuant to the first sentence hereof.

            "Applicable Premium" means with respect to a Security at any
redemption date, the greater of (1) 1.00% of the principal amount of such
Security at such time and (2) the excess of (A) the present value at such time
of (i) the redemption price of such Security on September 1, 2008 (such
redemption price being described in the second paragraph of section 5 of the
reverse side of the Securities, exclusive of any accrued interest) plus (ii) all
required remaining scheduled interest payments due on such Security through
September 1, 2008 (but excluding accrued and unpaid interest to the redemption

                                 The Securities

            SECTION 2.01. Form and Dating. Provisions relating to the Initial
Securities, the Private Exchange Securities and the Exchange Securities are set
forth in
<PAGE>

                                                                              30

the Rule 144A/Regulation S/IAI Appendix attached hereto (the "Appendix") which
is hereby incorporated in, and expressly made part of, this Indenture. The
Initial Securities and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit 1 to the Appendix which is hereby
incorporated in, and expressly made a part of, this Indenture. The Exchange
Securities, the Private Exchange Securities and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A, which is hereby
incorporated in and expressly made a part of this Indenture. The Securities may
have notations, legends or endorsements required by law, stock exchange rule,
agreements to which the Company is subject, if any, or usage (provided that any
such notation, legend or endorsement is in a form acceptable to the Company).
Each Security shall be dated the date of its authentication. The terms of the
Securities set forth in the Appendix and Exhibit A are part of the terms of this
Indenture.

            SECTION 2.02. Execution and Authentication. Two Officers shall sign
the Securities for the Company by manual or facsimile signature. The Company's
seal shall be impressed, affixed, imprinted or reproduced on the Securities and
may be in facsimile form.

            If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless.

            A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security. The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.

            On the Issue Date, the Trustee shall authenticate and deliver $154
million of 11% Second-Priority Senior Secured Notes Due 2011 and, at any time
and from time to time thereafter, the Trustee shall authenticate and deliver
Securities for original issue in an aggregate principal amount specified in such
order, in each case upon a written order of the Company signed by two Officers
or by an Officer and either an Assistant Treasurer or an Assistant Secretary of
the Company. Such order shall specify the amount of the Securities to be
authenticated and the date on which the original issue of Securities is to be
authenticated and, in the case of an issuance of Additional Securities pursuant
to Section 2.13 after the Issue Date, shall certify that such issuance is in
compliance with Section 4.03.

            The Trustee may appoint an authenticating agent reasonably
acceptable to the Company to authenticate the Securities. Unless limited by the
terms of such appointment, an authenticating agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, Paying Agent or agent
for service of notices and demands.

            SECTION 2.03. Registrar and Paying Agent. The Company shall maintain
an office or agency where Securities may be presented for registration of
transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent"). The Registrar
shall keep a register of the

<PAGE>

                                                                              31

Securities and of their transfer and exchange. The Company may have one or more
co-registrars and one or more additional paying agents. The term "Paying Agent"
includes any additional paying agent.

            The Company shall enter into an appropriate agency agreement with
any Registrar, Paying Agent or co-registrar not a party to this Indenture, which
shall incorporate the terms of the TIA. The agreement shall implement the
provisions of this Indenture that relate to such agent. The Company shall notify
the Trustee of the name and address of any such agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.07. The
Company or any Wholly Owned Subsidiary incorporated or organized within The
United States of America may act as Paying Agent, Registrar, co-registrar or
transfer agent.

            The Company initially appoints the Trustee as Registrar and Paying
Agent in connection with the Securities.

            SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to each due
date of the principal and interest on any Security, the Company shall deposit
with the Paying Agent a sum sufficient to pay such principal and interest when
so becoming due. The Company shall require each Paying Agent (other than the
Trustee) to agree in writing that the Paying Agent shall hold in trust for the
benefit of Securityholders or the Trustee all money held by the Paying Agent for
the payment of principal of or interest on the Securities and shall notify the
Trustee of any default by the Company in making any such payment. If the Company
or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as
Paying Agent and hold it as a separate trust fund. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any funds disbursed by the Paying Agent. Upon complying with this Section,
the Paying Agent shall have no further liability for the money delivered to the
Trustee.

            SECTION 2.05. Securityholder Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Securityholders. If the Trustee is not the
Registrar, the Company shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders.

            SECTION 2.06. Transfer and Exchange. The Securities shall be issued
in registered form and shall be transferable only upon the surrender of a
Security for registration of transfer. When a Security is presented to the
Registrar or a co-registrar with a request to register a transfer, the Registrar
shall register the transfer as requested if the requirements of this Indenture
and Section 8-401(1) of the Uniform Commercial Code are met. When Securities are
presented to the Registrar or a co-registrar with a request to exchange them for
an equal principal amount of Securities of other denominations, the Registrar
shall make the exchange as requested if the same requirements are met.

                                                                              32

            SECTION 2.07. Replacement Securities. If a mutilated Security is
surrendered to the Registrar or if the Holder of a Security claims that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee. If required by the Trustee or
the Company, such Holder shall furnish an indemnity bond sufficient in the
judgment of the Company and the Trustee to protect the Company, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of them
may suffer if a Security is replaced. The Company and the Trustee may charge the
Holder for their expenses in replacing a Security.

            Every replacement Security is an additional Obligation of the
Company.

            SECTION 2.08. Outstanding Securities. Securities outstanding at any
time are all Securities authenticated by the Trustee except for those canceled
by it, those delivered to it for cancellation and those described in this
Section as not outstanding. A Security does not cease to be outstanding because
the Company or an Affiliate of the Company holds the Security.

            If a Security is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee and the Company receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

            If the Paying Agent segregates and holds in trust, in accordance
with this Indenture, on a redemption date or maturity date money sufficient to
pay all principal and interest payable on that date with respect to the
Securities (or portions thereof) to be redeemed or maturing, as the case may be,
then on and after that date such Securities (or portions thereof) cease to be
outstanding and interest on them ceases to accrue.

            SECTION 2.09. Temporary Securities. Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities. Temporary Securities shall be substantially in the form of
definitive Securities but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and the Trustee shall authenticate definitive Securities and
deliver them in exchange for temporary Securities.

            SECTION 2.10. Cancellation. The Company at any time may deliver
Securities to the Trustee for cancellation. The Registrar and the Paying Agent
shall forward to the Trustee any Securities surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel and
dispose of (subject to the record retention requirements of the Exchange Act)
all Securities surrendered for registration of transfer, exchange, payment or
cancellation in its customary manner and deliver a certificate of such
destruction to the Company unless the Company directs the Trustee in writing to
deliver canceled Securities to the Company. The Company may not issue new
Securities to replace Securities it has redeemed, paid or delivered to the
Trustee for cancellation.

                                                                              33

            SECTION 2.11. Defaulted Interest. If the Company defaults in a
payment of interest on the Securities, the Company shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner. The Company may pay the defaulted interest to the persons who are
Securityholders on a subsequent special record date. The Company shall fix or
cause to be fixed any such special record date and payment date to the
reasonable satisfaction of the Trustee and shall promptly mail to each
Securityholder a notice that states the special record date, the payment date
and the amount of defaulted interest to be paid.

            SECTION 2.12. CUSIP Numbers. The Company in issuing the Securities
may use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall
use "CUSIP" numbers in notices of redemption as a convenience to Holders;
provided, however, that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Company shall promptly notify the Trustee of any change in the "CUSIP"
numbers.

            SECTION 2.13. Issuance of Additional Securities. After the Issue
Date, the Company shall be entitled, subject to its compliance with Section
4.03, to issue Additional Securities under this Indenture, which Securities
shall have identical terms as the Initial Securities issued on the Issue Date,
other than with respect to the date of issuance and issue price. All the
Securities issued under this Indenture shall be treated as a single class for
all purposes of this Indenture including waivers, amendments, redemptions and
offers to purchase.

            With respect to any Additional Securities, the Company shall set
forth in a resolution of the Board of Directors and an Officers' Certificate, a
copy of each which shall be delivered to the Trustee, the following information:

            (1) the aggregate principal amount of such Additional Securities to
      be authenticated and delivered pursuant to this Indenture and the
      provision of Section 4.03 that the Company is relying on to issue such
      Additional Securities;

            (2) the issue price, the issue date and the CUSIP number of such
      Additional Securities; provided, however, that no Additional Securities
      may be issued at a price that would cause such Additional Securities to
      have "original issue discount" within the meaning of Section 1273 of the
      Code; and

            (3) whether such Additional Securities shall be Initial Securities
      or shall be issued in the form of Exchange Securities as set forth in
      Exhibit A.

<PAGE>

                                                                              34

                                    ARTICLE 3

                                   Redemption

            SECTION 3.01. Notices to Trustee. If the Company elects to redeem
Securities pursuant to paragraph 5 of the Securities, it shall notify the
Trustee in writing of the redemption date and the principal amount of Securities
to be redeemed.

            The Company shall give each notice to the Trustee provided for in
this Section at least 60 days before the redemption date unless the Trustee
consents to a shorter period. Such notice shall be accompanied by an Officers'
Certificate and an Opinion of Counsel from the Company to the effect that such
redemption shall comply with the conditions herein.

            SECTION 3.02. Selection of Securities to Be Redeemed. If fewer than
all the Securities are to be redeemed, the Trustee shall select the Securities
to be redeemed pro rata to the extent practicable. The Trustee shall make the
selection from outstanding Securities not previously called for redemption. The
Trustee may select for redemption portions of the principal of Securities that
have denominations larger than $1,000. Securities and portions of them the
Trustee selects shall be in principal amounts of $1,000 or a whole multiple of
$1,000. Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption. The
Trustee shall notify the Company promptly of the Securities or portions of
Securities to be redeemed.

            SECTION 3.03. Notice of Redemption. At least 30 days but not more
than 60 days before a date for redemption of Securities, the Company shall mail
a notice of redemption by first-class mail to each Holder of Securities to be
redeemed at such Holder's registered address, subject to the provisions below.

            The notice shall identify the Securities to be redeemed and shall
state:

            (1)   the redemption date;

            (2) the redemption price;

            (3) the name and address of the Paying Agent;

            (4) that Securities called for redemption must be surrendered to the
      Paying Agent to collect the redemption price;

            (5) if fewer than all the outstanding Securities are to be redeemed,
      the identification and principal amounts of the particular Securities to
      be redeemed;

            (6) that, unless the Company defaults in making such redemption
      payment, interest on Securities (or portion thereof) called for redemption
      ceases to accrue on and after the redemption date; and

<PAGE>

                                                                              35

            (7) that no representation is made as to the correctness or accuracy
      of the CUSIP number, if any, listed in such notice or printed on the
      Securities.

            At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at the Company's expense. In such event,
the Company shall provide the Trustee with a form of notice containing the
information required by this Section.

            SECTION 3.04. Effect of Notice of Redemption. Once notice of
redemption is mailed, Securities called for redemption become due and payable on
the redemption date and at the redemption price stated in the notice. Upon
surrender to the Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on the related interest payment date). Failure to give
notice or any defect in the notice to any Holder shall not affect the validity
of the notice to any other Holder.

            SECTION 3.05. Deposit of Redemption Price. Prior to the redemption
date, the Company shall deposit with the Paying Agent (or, if the Company or a
Subsidiary is the Paying Agent, shall segregate and hold in trust) money
sufficient to pay the redemption price of and accrued interest on all Securities
to be redeemed on that date other than Securities or portions of Securities
called for redemption which have been delivered by the Company to the Trustee
for cancellation.

            SECTION 3.06. Securities Redeemed in Part. Upon surrender of a
Security that is redeemed in part, the Company shall execute and the Trustee
shall authenticate for the Holder (at the Company's expense) a new Security
equal in principal amount to the unredeemed portion of the Security surrendered.

                                   ARTICLE 4

                                   Covenants

            SECTION 4.01. Payment of Securities. The Company shall promptly pay
the principal of and interest on the Securities on the dates and in the manner
provided in the Securities and in this Indenture. Principal and interest shall
be considered paid on the date due if on such date the Trustee or the Paying
Agent holds in accordance with this Indenture money sufficient to pay all
principal and interest then due.

            The Company shall pay interest on overdue principal at the rate
specified therefor in the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

            SECTION 4.02. SEC Reports. At all times from and after the date of
the commencement of an exchange offer or the effectiveness of a shelf
registration statement relating to the Securities (the "Registration"),
notwithstanding that the Company may not be required to be or remain subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act, the
Company shall file with the SEC (subject to the next sentence) and

<PAGE>

                                                                              36

provide the Trustee and Securityholders with such annual and other reports as
are specified in Sections 13 and 15(d) of the Exchange Act and applicable to a
U.S. corporation subject to such Sections, such reports to be so filed and
provided at the times specified for the filings of such reports under such
Sections and containing all the information, audit reports and exhibits required
for such reports. If at any time, the Company is not subject to the periodic
reporting requirements of the Exchange Act for any reason, the Company shall
nevertheless continue filing the reports specified in the preceding sentence
with the SEC within the time periods required unless the SEC shall not accept
such a filing. The Company agrees that it shall not take any action for the
purpose of causing the SEC not to accept any such filings. If, notwithstanding
the foregoing, the SEC shall not accept such filings for any reason, the Company
shall post the reports specified in the preceding sentence on its website within
the time periods that would apply if the Company were required to file those
reports with the SEC.

            At any time that any of the Company's Subsidiaries are Unrestricted
Subsidiaries, then the quarterly and annual financial information required by
the preceding paragraph shall include a reasonably detailed presentation, either
on the face of the financial statements or in the footnotes thereto, and in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," of the financial condition and results of operations of the Company
and its Restricted Subsidiaries separate from the financial condition and
results of operations of the Unrestricted Subsidiaries of the Company.

            At all times prior to the Registration, upon the request of any
Holder or any prospective purchaser of the Securities designated by a Holder,
the Company shall supply to such Holder or such prospective purchaser the
information required under Rule 144A under the Securities Act.

            In addition, the Company shall furnish to the Holder of the
Securities and to prospective investors, upon the written requests of such
Holders, any information required to be delivered pursuant to Rule 144A(d)(4)
under the Securities Act so long as any Securities are not freely transferable
under the Securities Act. The Company also shall comply with the other
provisions of TIA Section 314(a).

            Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

            SECTION 4.03. Limitation on Indebtedness. (a) The Company shall not,
and shall not permit any Restricted Subsidiary to, Incur, directly or
indirectly, any Indebtedness; provided, however, that the Company and the
Subsidiary Guarantors shall be entitled to Incur Indebtedness if, on the date of
such Incurrence and after giving effect thereto on a pro forma basis, the Fixed
Charge Coverage Ratio exceeds 2.00 to 1.

<PAGE>

                                                                              37

            (b) Notwithstanding the foregoing paragraph (a), the Company and the
Restricted Subsidiaries shall be entitled to Incur any or all of the following
Indebtedness:

            (1) Indebtedness Incurred by the Company and the Subsidiary
      Guarantors pursuant to the Credit Facility (other than Indebtedness
      Incurred pursuant to clause (10) of this paragraph (b)); provided,
      however, that, immediately after giving effect to any such Incurrence, the
      aggregate principal amount of all Indebtedness Incurred under this clause
      (b)(1) and then outstanding does not exceed $30.0 million;

            (2) Indebtedness owed to and held by the Company or a Restricted
      Subsidiary; provided, however, that (A) any subsequent issuance or
      transfer of any Capital Stock which results in any such Restricted
      Subsidiary ceasing to be a Restricted Subsidiary or any subsequent
      transfer of such Indebtedness (other than to the Company or a Restricted
      Subsidiary) shall be deemed, in each case, to constitute the Incurrence of
      such Indebtedness by the obligor thereon and, (B) if the Company is the
      obligor on such Indebtedness, such Indebtedness is expressly subordinated
      to the prior payment in full in cash of all obligations with respect to
      the Securities and (C) if a Subsidiary Guarantor is the obligor on such
      Indebtedness, such Indebtedness is expressly subordinated to the prior
      payment in full in cash of all obligations of such Subsidiary Guarantor or
      with respect to its Subsidiary Guarantee;

            (3) the Securities (other than any Additional Securities);

            (4) Indebtedness outstanding on the Issue Date (other than
      Indebtedness described in clause (1), (2), (3) or (6) of this Section
      4.03(b));

            (5) Indebtedness of a Restricted Subsidiary Incurred and outstanding
      on or prior to the date on which such Subsidiary was acquired by the
      Company (other than Indebtedness Incurred in connection with, or to
      provide all or any portion of the funds or credit support utilized to
      consummate, the transaction or series of related transactions pursuant to
      which such Subsidiary became a Subsidiary or was acquired by the Company);
      provided, however, that on the date of such acquisition and after giving
      pro forma effect thereto, the Company would have been entitled to Incur at
      least $1.00 of additional Indebtedness pursuant to Section 4.03(a);

            (6) the Mezzanine Debt;

            (7) Refinancing Indebtedness in respect of Indebtedness Incurred
      pursuant to Section 4.03(a) or pursuant to clause (3), (4), (5) or (6) of
      this Section 4.03(b) or this clause (7); provided, however, that to the
      extent such Refinancing Indebtedness directly or indirectly Refinances
      Indebtedness of a Subsidiary Incurred pursuant to clause (5), such
      Refinancing Indebtedness shall be Incurred only by such Subsidiary;

<PAGE>

                                                                              38

            (8) Hedging Obligations consisting of Interest Rate Agreements
      directly related to Indebtedness permitted to be Incurred by the Company
      and the Restricted Subsidiaries pursuant to this Indenture;

            (9) Obligations in respect of letters of credit, performance, bid
      and surety bonds and completion guarantees provided by the Company or any
      Restricted Subsidiary in the ordinary course of business;

            (10) Indebtedness consisting of letters of credit issued pursuant to
      the Credit Agreement, not to exceed $10.0 million at any time issued and
      outstanding;

            (11) Indebtedness arising from the honoring by a bank or other
      financial institution of a check, draft or similar instrument drawn
      against insufficient funds in the ordinary course of business; provided,
      however, that such Indebtedness is extinguished within two Business Days
      of its Incurrence;

            (12) Indebtedness consisting of the Subsidiary Guarantee of a
      Subsidiary Guarantor and any Guarantee by a Subsidiary Guarantor of
      Indebtedness Incurred pursuant to Section 4.03(a) or pursuant to clause
      (1), (2), (3), (4) or (6) of this paragraph (b) or pursuant to clause (7)
      of this paragraph (b) to the extent the Refinancing Indebtedness Incurred
      thereunder directly or indirectly Refinances Indebtedness Incurred
      pursuant to Section 4.03(a) or pursuant to clause (3), (4) or (6) of this
      paragraph (b); and

            (13) Indebtedness of the Company or a Subsidiary Guarantor in an
      aggregate principal amount which, when taken together with all other
      Indebtedness of the Company and the Subsidiary Guarantors outstanding on
      the date of such Incurrence (other than Indebtedness permitted by clauses
      (1) through (12) of this Section 4.03(b) or Section 4.03(a)), does not
      exceed $5.0 million.

            (c) Notwithstanding the foregoing, neither the Company nor any
Subsidiary Guarantor shall Incur any Indebtedness pursuant to Section 4.03(b) if
the proceeds thereof are used, directly or indirectly, to Refinance any
Subordinated Obligations of the Company or a Subsidiary Guarantor unless such
Indebtedness shall be subordinated to the Securities or to the applicable
Subsidiary Guarantee to at least the same extent as such Subordinated
Obligations.

            (d) For purposes of determining compliance with this Section 4.03,
(1) any Indebtedness remaining outstanding under the Credit Facility after the
application of the net proceeds from the sale of the Securities shall be treated
as Incurred on the Issue Date under Section 4.03(b)(1), (2) in the event that an
item of Indebtedness (or any portion thereof) meets the criteria of more than
one of the types of Indebtedness described herein, the Company, in its sole
discretion, shall classify such item of Indebtedness (or any portion thereof) at
the time of Incurrence and shall only be required to include the amount and type
of such Indebtedness in one of the above clauses and (3) the Company shall be
entitled to divide and classify an item of Indebtedness in more than one of the

            SECTION 4.04. Limitation on Restricted Payments. (a) The Company
shall not, and shall not permit any Restricted Subsidiary, directly or
indirectly, to make a Restricted Payment if at the time the Company or such
Restricted Subsidiary makes such Restricted Payment:

            (1) a Default shall have occurred and be continuing (or would result
      therefrom);

            (2) the Company is not entitled to Incur an additional $1.00 of
      Indebtedness under Section 4.03(a); or

            (3) the aggregate amount of such Restricted Payment and all other
      Restricted Payments since the Issue Date would exceed the sum of (without
      duplication):

                  (A) 50% of the Consolidated Net Income accrued during the
            period (treated as one accounting period) from the beginning of the
            fiscal quarter immediately following the fiscal quarter during which
            the Issue Date occurs to the end of the most recent fiscal quarter
            ending at least 45 days prior to the date of such Restricted Payment
            (or, in case such Consolidated Net Income shall be a deficit, minus
            100% of such deficit); plus

                  (B) 100% of the aggregate Net Cash Proceeds received by the
            Company from the issuance or sale of its Capital Stock (other than
            Disqualified Stock) subsequent to the Issue Date (other than an
            issuance or sale to a Subsidiary of the Company and other than an
            issuance or sale to an employee stock ownership plan or to a trust
            established by the Company or any of its Subsidiaries for the
            benefit of their employees) and 100% of any cash capital
            contribution received by the Company from its stockholders
            subsequent to the Issue Date; plus

                  (C) the amount by which Indebtedness of the Company is reduced
            upon the conversion or exchange subsequent to the Issue Date of any
            Indebtedness of the Company convertible or exchangeable for Capital
            Stock (other than Disqualified Stock) of the Company (less the
            amount of any cash, or the fair value of any other property,
            distributed by the Company upon such conversion or exchange);
            provided, however, that the foregoing amount shall not exceed the
            Net Cash Proceeds received by the Company or any Restricted
            Subsidiary from the sale of such Indebtedness (excluding Net Cash
            Proceeds from sales to a Subsidiary of the Company or to an employee
            stock ownership plan or to a trust established by the Company or any
            of its Subsidiaries for the benefit of their employees); plus

                  (D) an amount equal to the sum of (i) the net reduction in the
            Investments (other than Permitted Investments) made by the Company
            or

<PAGE>

                                                                              40

            any Restricted Subsidiary in any Person resulting from repurchases,
            repayments or redemptions of such Investments by such Person,
            proceeds realized on the sale of such Investment and proceeds
            representing the return of capital (excluding dividends and
            distributions), in each case received by the Company or any
            Restricted Subsidiary and (ii) to the extent such Person is an
            Unrestricted Subsidiary, the portion (proportionate to the Company's
            equity interest in such Subsidiary) of the fair market value of the
            net assets of such Unrestricted Subsidiary at the time such
            Unrestricted Subsidiary is designated a Restricted Subsidiary;
            provided, however, that the foregoing sum shall not exceed, in the
            case of any such Person or Unrestricted Subsidiary, the amount of
            Investments (excluding Permitted Investments) previously made (and
            treated as a Restricted Payment) by the Company or any Restricted
            Subsidiary in such Person or Unrestricted Subsidiary.

            (b) The provisions of Section 4.04(a) shall not prohibit:

            (1) any Restricted Payment made out of the Net Cash Proceeds of the
      substantially concurrent sale of, or made by exchange for, Capital Stock
      of the Company (other than Disqualified Stock and other than Capital Stock
      issued or sold to a Subsidiary of the Company or an employee stock
      ownership plan or to a trust established by the Company or any of its
      Subsidiaries for the benefit of their employees) or a substantially
      concurrent cash capital contribution received by the Company from its
      stockholders; provided, however, that (A) such Restricted Payment shall be
      excluded in the calculation of the amount of Restricted Payments and (B)
      the Net Cash Proceeds from such sale or such cash capital contribution (to
      the extent so used for such Restricted Payment) shall be excluded from the
      calculation of amounts under Section 4.04(a)(3)(B);

            (2) any purchase, repurchase, redemption, defeasance or other
      acquisition or retirement for value of Subordinated Obligations of the
      Company or a Subsidiary Guarantor made by exchange for, or out of the
      proceeds of the substantially concurrent Incurrence of, Indebtedness of
      such Person which is permitted to be Incurred pursuant to Section 4.03;
      provided, however, that notwithstanding anything to the contrary contained
      in this clause (2) of paragraph (b), any purchase, repurchase, redemption,
      defeasance or other acquisition or retirement for value of the Mezzanine
      Debt pursuant to this clause (2) may only be made by exchange for, or out
      of the proceeds of, the substantially concurrent Incurrence of
      Subordinated Obligations of the Company; and provided further, however,
      that any purchase, repurchase, redemption, defeasance or other acquisition
      or retirement for value made pursuant to this clause (2) of paragraph (b)
      shall be excluded in the calculation of the amount of Restricted Payments;

            (3) dividends paid within 60 days after the date of declaration
      thereof if at such date of declaration such dividend would have complied
      with this Section 4.04; provided, however, that at the time of payment of
      such dividend, no other Default shall have occurred and be continuing (or
      result therefrom);

<PAGE>

                                                                              41

      provided further, however, that such dividend shall be included in the
      calculation of the amount of Restricted Payments;

            (4) so long as no Default has occurred and is continuing, the
      purchase, redemption or other acquisition of shares of Capital Stock of
      the Company or any of its Subsidiaries from employees, former employees,
      directors or former directors of the Company or any of its Subsidiaries
      (or permitted transferees of such employees, former employees, directors
      or former directors), pursuant to the terms of the agreements (including
      employment agreements) or plans (or amendments thereto) approved by the
      Board of Directors under which such individuals purchase or sell or are
      granted the option to purchase or sell, shares of such Capital Stock;
      provided, however, that the aggregate amount of such Restricted Payments
      (excluding amounts representing cancellation of Indebtedness) shall not
      exceed $2.0 million in any calendar year; provided further, however, that
      such repurchases and other acquisitions shall be excluded in the
      calculation of the amount of Restricted Payments;

            (5) the declaration and payments of dividends on Disqualified Stock
      issued pursuant to Section 4.03; provided, however, that, at the time of
      payment of such dividend, no Default shall have occurred and be continuing
      (or result therefrom); provided further, however, that such dividends
      shall be excluded in the calculation of the amount of Restricted Payments;

            (6) repurchases of Capital Stock deemed to occur upon exercise of
      stock options if such Capital Stock represents a portion of the exercise
      price of such options; provided, however, that such Restricted Payments
      shall be excluded in the calculation of the amount of Restricted Payments;

            (7) cash payments in lieu of the issuance of fractional shares in
      connection with the exercise of warrants, options or other securities
      convertible into or exchangeable for Capital Stock of the Company;
      provided, however, that any such cash payment shall not be for the purpose
      of evading the limitation of this Section 4.04 (as determined in good
      faith by the Board of Directors); provided further, however, that such
      payments shall be excluded in the calculation of the amount of Restricted
      Payments;

            (8) in the event of a Change of Control, and if no Default shall
      have occurred and be continuing, the payment, purchase, redemption,
      defeasance or other acquisition or retirement of Subordinated Obligations
      of the Company or any Subsidiary Guarantor, in each case, at a purchase
      price not greater than 101% of the principal amount of such Subordinated
      Obligations, plus any accrued and unpaid interest thereon; provided,
      however, that prior to such payment, purchase, redemption, defeasance or
      other acquisition or retirement, the Company (or a third party to the
      extent permitted by this Indenture) has made a Change of Control Offer
      with respect to the Securities as a result of such Change of Control and
      has repurchased all Securities validly tendered and not withdrawn in
      connection with such Change of Control Offer; provided further, however,
      that

      such payments, purchases, redemptions, defeasances or other acquisitions
      or retirements shall be included in the calculation of the amount of
      Restricted Payments; or

            (9) payments of intercompany subordinated Indebtedness, the
      Incurrence of which was permitted under Section 4.03(b)(2); provided,
      however, that no Default has occurred and is continuing or would otherwise
      result therefrom; provided further, however, that such payments shall be
      excluded in the calculation of the amount of Restricted Payments.

            SECTION 4.05. Limitation on Restrictions on Distributions from
Restricted Subsidiaries. The Company shall not, and shall not permit any
Restricted Subsidiary to, create or otherwise cause or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any
Restricted Subsidiary to (a) pay dividends or make any other distributions on
its Capital Stock to the Company or a Restricted Subsidiary or pay any
Indebtedness owed to the Company, (b) make any loans or advances to the Company
or (c) transfer any of its property or assets to the Company, except:

            (1) with respect to clauses (a), (b) and (c),

                  (A) any encumbrance or restriction pursuant to an agreement in
            effect at or entered into on the Issue Date (including the Credit
            Facility);

                  (B) any encumbrance or restriction with respect to a
            Restricted Subsidiary pursuant to an agreement relating to any
            Indebtedness Incurred by such Restricted Subsidiary on or prior to
            the date on which such Restricted Subsidiary was acquired by the
            Company (other than Indebtedness Incurred as consideration in, or to
            provide all or any portion of the funds or credit support utilized
            to consummate, the transaction or series of related transactions
            pursuant to which such Restricted Subsidiary became a Restricted
            Subsidiary or was acquired by the Company) and outstanding on such
            date;

                  (C) any encumbrance or restriction pursuant to an agreement
            effecting a Refinancing of Indebtedness Incurred pursuant to an
            agreement referred to in Section 4.05(1)(A) or (B) or this clause
            (C) or contained in any amendment to an agreement referred to in
            Section 4.05(1)(A) or (B) or this clause (C); provided, however,
            that the encumbrances and restrictions with respect to such
            Restricted Subsidiary contained in any such refinancing agreement or
            amendment are no less favorable to the Securityholders than
            encumbrances and restrictions with respect to such Restricted
            Subsidiary contained in such predecessor agreements; and

                  (D) any encumbrance or restriction with respect to a
            Restricted Subsidiary imposed pursuant to an agreement entered into
            for the sale or

            disposition of all or substantially all the Capital Stock or assets
            of such Restricted Subsidiary pending the closing of such sale or
            disposition; and

            (2) with respect to clause (c) only,

                  (A) any encumbrance or restriction consisting of customary
            nonassignment provisions in leases governing leasehold interests to
            the extent such provisions restrict the transfer of the lease or the
            property leased thereunder consistent with the past practices of the
            Company or the Restricted Subsidiaries; and

                  (B) any encumbrance or restriction contained in security
            agreements or mortgages securing Indebtedness of a Restricted
            Subsidiary to the extent such encumbrance or restriction restricts
            the transfer of the property subject to such security agreements or
            mortgages.

            SECTION 4.06. Limitation on Sales of Assets and Subsidiary Stock.
(a) The Company shall not, and shall not permit any Restricted Subsidiary to,
directly or indirectly, consummate any Asset Disposition of any Collateral
unless (1) the Company or such Restricted Subsidiary receives consideration at
the time of such Asset Disposition at least equal to the fair market value
(including as to the value of all non-cash consideration), as determined in good
faith by the Board of Directors, of the shares and assets subject to such Asset
Disposition; (2) at least 75% of the consideration thereof received by the
Company or such Restricted Subsidiary is in the form of cash or cash
equivalents; and (3) an amount equal to 100% of the Net Available Cash from such
Asset Disposition is paid directly by the purchaser thereof to the Intercreditor
Agent, or, if no First-Priority Lien Obligations are outstanding, the Trustee,
to be held in trust and applied by the Company (or such Restricted Subsidiary,
as the case may be) at the Company's election: (A) to acquire Additional Assets,
which Additional Assets are concurrently with their acquisition added to the
Collateral securing the Securities; (B) to repay outstanding First-Priority Lien
Obligations; or (C) to make an offer to the holders of the Securities pursuant
to and subject to the conditions contained in this Indenture; in each case
within six months from the later of the date of such Asset Disposition or the
receipt of such Net Available Cash.

            (b) The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, consummate any Asset Disposition (other
than an Asset Disposition of Collateral) unless (1) the Company or such
Restricted Subsidiary receives consideration at the time of such Asset
Disposition at least equal to the fair market value (including as to the value
of all non-cash consideration), as determined in good faith by the Board of
Directors, of the shares and assets subject to such Asset Disposition, (2) at
least 75% of the consideration thereof received by the Company or such
Restricted Subsidiary is in the form of cash or cash equivalents and (3) an
amount equal to 100% of the Net Available Cash from such Asset Disposition is
applied by the Company (or such Restricted Subsidiary), as the case may be (A)
first, to the extent the Company elects (or is required by the terms of any
Indebtedness), to prepay, repay, redeem or purchase Senior Indebtedness of the
Company or Indebtedness (other than any

<PAGE>

                                                                              44

Disqualified Stock) of a Restricted Subsidiary (in each case other than
Indebtedness owed to the Company or an Affiliate of the Company) within one year
from the later of the date of such Asset Disposition or the receipt of such Net
Available Cash; (B) second, to the extent of the balance of such Net Available
Cash after application in accordance with clause (A), to the extent the Company
elects, to acquire Additional Assets within one year from the later of the date
of such Asset Disposition or the receipt of such Net Available Cash; and (C)
third, to the extent of the balance of such Net Available Cash after application
in accordance with clauses (A) or (B), to make an Offer to the holders of the
Securities (and to holders of other Senior Indebtedness of the Company or of a
Subsidiary Guarantor designated by the Company) to purchase Securities (and such
other Senior Indebtedness of the Company or of a Subsidiary Guarantor) pursuant
to and subject to the conditions contained in this Indenture; provided, however,
that in connection with any prepayment, repayment or purchase of Indebtedness
pursuant to clause (A) or (C) above, the Company or such Restricted Subsidiary
shall permanently retire such Indebtedness and shall cause the related loan
commitment (if any) to be permanently reduced in an amount equal to the
principal amount so prepaid, repaid or purchased.

            (c) Notwithstanding the provisions of Section 4.06(b), the Company
and the Restricted Subsidiaries shall not be required to apply any Net Available
Cash in accordance with Section 4.06(b) except to the extent that the aggregate
Net Available Cash from all Asset Dispositions subject to Section 4.06(b) which
is not applied in accordance with Section 4.06(b) exceeds $10.0 million. Pending
application of Net Available Cash pursuant to this Section 4.06(a), such Net
Available Cash shall be invested in Temporary Cash Investments or applied to
temporarily reduce revolving credit indebtedness.

            (d) For the purposes of this Section 4.06, the following are deemed
to be cash or cash equivalents: (i) the assumption or discharge of Indebtedness
of the Company (other than obligations in respect of Disqualified Stock of the
Company) or any Restricted Subsidiary (other than obligations in respect of
Disqualified Stock or Preferred Stock of a Subsidiary Guarantor) and the release
of the Company or such Restricted Subsidiary from all liability on such
Indebtedness in connection with such Asset Disposition and (ii) securities
received by the Company or any Restricted Subsidiary from the transferee that
are promptly converted by the Company or such Restricted Subsidiary into cash,
to the extent of cash received in that conversion.

            (e) In the event of an Asset Disposition that requires the purchase
of Securities (and any other Senior Indebtedness of the Company or of a
Subsidiary Guarantor) pursuant to Section 4.06(a)(3)(C) or Section
4.06(b)(3)(C), the Company shall purchase Securities tendered pursuant to an
offer by the Company for the Securities (and such other Senior Indebtedness)
(the "Offer") at a purchase price of 100% of their principal amount (or, in the
event such other Senior Indebtedness was issued with significant original issue
discount, 100% of the accreted value thereof), without premium, plus accrued but
unpaid interest (or, in respect of such other Senior Indebtedness of the
Company, such lesser price, if any, as may be provided for by the terms of such
Senior Indebtedness) in accordance with the procedures (including prorating in
the event of

<PAGE>

                                                                              45

oversubscription) set forth in Section 4.06(c). If the aggregate purchase price
of the securities tendered exceeds the Net Available Cash allotted to their
purchase, the Company shall select the securities to be purchased on a pro rata
basis but in round denominations, which in the case of the Securities shall be
denominations of $1,000 principal amount or multiples thereof. The Company shall
not be required to make an Offer to purchase Securities (and other Senior
Indebtedness of the Company) pursuant to Section 4.06(b) if the Net Available
Cash available therefor is less than $10.0 million (which lesser amount shall be
carried forward for purposes of determining whether such an Offer is required
with respect to the Net Available Cash from any subsequent Asset Disposition).
Upon completion of such an Offer, Net Available Cash shall be deemed to be
reduced by the aggregate amount of such Offer and any then remaining Net
Available Cash following such Offer may be used by the Company for any purpose
not prohibited by this Indenture.

            (1) Promptly, and in any event within 10 days after the Company
      becomes obligated to make an Offer, the Company shall deliver to the
      Trustee and send, by first-class mail to each Holder, a written notice
      stating that the Holder may elect to have his Securities purchased by the
      Company either in whole or in part (subject to prorating as described in
      Section 4.06(e) in the event the Offer is oversubscribed) in integral
      multiples of $1,000 of principal amount, at the applicable purchase price.
      The notice shall specify a purchase date not less than 30 days nor more
      than 60 days after the date of such notice (the "Purchase Date") and shall
      contain such information concerning the business of the Company which the
      Company in good faith believes shall enable such Holders to make an
      informed decision (which at a minimum shall include (A) the most recently
      filed Annual Report on Form 10-K (including audited consolidated financial
      statements) of the Company, the most recent subsequently filed Quarterly
      Report on Form 10-Q and any Current Report on Form 8-K of the Company
      filed subsequent to such Quarterly Report, other than Current Reports
      describing Asset Dispositions otherwise described in the offering
      materials (or corresponding successor reports), (B) a description of
      material developments in the Company's business subsequent to the date of
      the latest of such Reports, and (C) if material, appropriate pro forma
      financial information) and all instructions and materials necessary to
      tender Securities pursuant to the Offer, together with the information
      contained in clause (3).

            (2) Not later than the date upon which written notice of an Offer is
      delivered to the Trustee as provided below, the Company shall deliver to
      the Trustee an Officers' Certificate as to (A) the amount of the Offer
      (the "Offer Amount"), including information as to any other Senior
      Indebtedness included in the Offer, (B) the allocation of the Net
      Available Cash from the Asset Dispositions pursuant to which such Offer is
      being made and (C) the compliance of such allocation with the provisions
      of Section 4.06(a), (b), (c) and (d). On such date, the Company shall also
      irrevocably deposit with the Trustee or with a Paying Agent (or, if the
      Company is acting as its own Paying Agent, segregate and hold in trust) in
      Temporary Cash Investments, maturing on the last day prior to the Purchase
      Date or on the Purchase Date if funds are immediately available

                                                                              46

      by open of business, an amount equal to the Offer Amount to be held for
      payment in accordance with the provisions of this Section. If the Offer
      includes other Senior Indebtedness, the deposit described in the preceding
      sentence may be made with any other paying agent pursuant to arrangements
      satisfactory to the Trustee. Upon the expiration of the period for which
      the Offer remains open (the "Offer Period"), the Company shall deliver to
      the Trustee for cancellation the Securities or portions thereof which have
      been properly tendered to and are to be accepted by the Company. The
      Trustee shall, on the Purchase Date, mail or deliver payment (or cause the
      delivery of payment) to each tendering Holder in the amount of the
      purchase price. In the event that the aggregate purchase price of the
      Securities delivered by the Company to the Trustee is less than the Offer
      Amount applicable to the Securities, the Trustee shall deliver the excess
      to the Company immediately after the expiration of the Offer Period.

            (3) Holders electing to have a Security purchased shall be required
      to surrender the Security, with an appropriate form duly completed, to the
      Company at the address specified in the notice at least three Business
      Days prior to the Purchase Date. Holders shall be entitled to withdraw
      their election if the Trustee or the Company receives not later than one
      Business Day prior to the Purchase Date, a telex, facsimile transmission
      or letter setting forth the name of the Holder, the principal amount of
      the Security which was delivered for purchase by the Holder and a
      statement that such Holder is withdrawing his election to have such
      Security purchased. Holders whose Securities are purchased only in part
      shall be issued new Securities equal in principal amount to the
      unpurchased portion of the Securities surrendered.

            (4) At the time the Company delivers Securities to the Trustee which
      are to be accepted for purchase, the Company shall also deliver an
      Officers' Certificate stating that such Securities are to be accepted by
      the Company pursuant to and in accordance with the terms of this Section.
      A Security shall be deemed to have been accepted for purchase at the time
      the Trustee, directly or through an agent, mails or delivers payment
      therefor to the surrendering Holder.

            (f) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the purchase of Securities pursuant to this
Section 4.06. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this Section 4.06, the Company shall
comply with the applicable securities laws and regulations and shall not be
deemed to have breached its obligations under this Section 4.06 by virtue of its
compliance with such securities laws or regulations.

            SECTION 4.07. Limitation on Affiliate Transactions. (a) The Company
shall not, and shall not permit any Restricted Subsidiary to, enter into or
permit to exist any transaction (including the purchase, sale, lease or exchange
of any property, employee compensation arrangements or the rendering of any
service) with, or for the benefit of, any Affiliate of the Company (an
"Affiliate Transaction") unless (1) the terms thereof are no less favorable to
the Company or such Restricted Subsidiary than those

<PAGE>

                                                                              47

that could be obtained at the time of the Affiliate Transaction in arm's-length
dealings with a Person who is not an Affiliate; (2) if such Affiliate
Transaction involves an amount in excess of $5.0 million, the terms of the
Affiliate Transaction are set forth in writing and a majority of the Board of
Directors of the Company disinterested with respect to such Affiliate
Transaction have determined in good faith that the criteria set forth in clause
(1) are satisfied and have approved the relevant Affiliate Transaction as
evidenced by a resolution of the Board of Directors; and (3) if such Affiliate
Transaction involves an amount in excess of $10.0 million, the Board of
Directors shall also have received a written opinion from an Independent
Qualified Party to the effect that such Affiliate Transaction is fair, from a
financial standpoint, to the Company and its Restricted Subsidiaries or is not
less favorable to the Company and its Restricted Subsidiaries than could
reasonably be expected to be obtained at the time in an arm's-length transaction
with a Person who was not an Affiliate.

            (b) The provisions of Section 4.07(a) shall not prohibit (1) any
Investment (other than a Permitted Investment) or other Restricted Payment, in
each case permitted to be made pursuant to (but only to the extent included in
the calculation of the amount of Restricted Payments made pursuant to Section
4.04(a)(3); (2) any issuance of securities, or other payments, awards or grants
in cash, securities or otherwise pursuant to, or the funding of, employment
arrangements, stock options and stock ownership plans approved by the Board of
Directors, (3) loans or advances to employees in the ordinary course of business
in accordance with the past practices of the Company or its Restricted
Subsidiaries, but in any event not to exceed $2.0 million in the aggregate
outstanding at any one time; (4) the payment of reasonable fees to directors of
the Company and its Restricted Subsidiaries who are not employees of the Company
or its Restricted Subsidiaries; (5) any transaction with the Company, a
Restricted Subsidiary or joint venture or similar entity which would constitute
an Affiliate Transaction solely because the Company or a Restricted Subsidiary
owns an equity interest in or otherwise controls such Restricted Subsidiary,
joint venture or similar entity; (6) the issuance or sale of any Capital Stock
(other than Disqualified Stock) of the Company; (7) the payment of (i) an annual
consulting services fee, not to exceed $750,000 in any twelve month period,
pursuant to the Consulting Services Agreement, (ii) annual directors and other
services fees, not to exceed $200,000 in any twelve month period, pursuant to
the Stockholders' Agreement, (iii) consulting services fees, in an amount equal
to 2% of the consideration received by the Company upon the initial public
offering of its capital stock or the sale of all or substantially all of its
assets, pursuant to the Consulting Services Agreement, (iv) professional service
fees, in an amount equal to 2% of the value of any transaction in which the
Company (A) sells all or substantially all of its assets or a majority of its
capital stock, (B) consummates the acquisition of another company or (C) secures
any debt or equity financing, in each case pursuant to the Professional Services
Agreement and (v) reasonable out-of-pocket expenses related to the foregoing, in
each case, by the Company or any of its Restricted Subsidiaries to H.I.G.; and
(8) any agreement as in effect on the Issue Date and described in the Offering
Circular or any renewals or extensions of any such agreement (so long as such
renewals or extensions are not less favorable to the Company or the Restricted
Subsidiaries) and the transactions evidenced thereby.

            SECTION 4.08. Limitation on Line of Business. The Company shall not,
and shall not permit any Restricted Subsidiary, to engage in any business other
than a Related Business.

            SECTION 4.09. Limitation on the Sale or Issuance of Capital Stock of
Restricted Subsidiaries. The Company:

            (1) shall not, and shall not permit any Restricted Subsidiary to,
      sell, lease, transfer or otherwise dispose of any Capital Stock of any
      Restricted Subsidiary to any Person (other than to the Company or a Wholly
      Owned Subsidiary); and

            (2) shall not permit any Restricted Subsidiary to issue any of its
      Capital Stock (other than, if necessary, shares of its Capital Stock
      constituting directors' or other legally required qualifying shares) to
      any Person (other than to the Company or a Wholly Owned Subsidiary) unless

                  (A) immediately after giving effect to such issuance, sale or
            other disposition, neither the Company nor any of its Subsidiaries
            own any Capital Stock of such Restricted Subsidiary; or

                  (B) immediately after giving effect to such issuance, sale or
            other disposition, such Restricted Subsidiary would no longer
            constitute a Restricted Subsidiary and any Investment in such Person
            remaining after giving effect thereto is treated as a new Investment
            by the Company and such Investment would be permitted to be made
            under Section 4.04 if made on the date of such issuance, sale or
            other disposition.

            For purposes of this Section 4.09, the creation of a Lien on any
Capital Stock of a Restricted Subsidiary to secure Indebtedness of the Company
or any of its Restricted Subsidiaries shall not be deemed to be a violation of
this Section 4.09; provided, however, that any sale or other disposition by the
secured party of such Capital Stock following foreclosure of its Lien shall be
subject to this Section 4.09.

            SECTION 4.10. Change of Control. (a) Upon the occurrence of a Change
of Control, each Holder shall have the right to require that the Company
purchase such Holder's Securities at a purchase price in cash equal to 101% of
the principal amount thereof on the date of purchase plus accrued and unpaid
interest, if any, to the date of purchase (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date), in accordance with the terms contemplated in Section
4.10(b).

            (b) Within 30 days following any Change of Control, the Company
shall mail a notice to each Holder with a copy to the Trustee (the "Change of
Control Offer") stating:

            (1) that a Change of Control has occurred and that such Holder has
      the right to require the Company to purchase such Holder's Securities at a
      purchase

<PAGE>

                                                                              49

      price in cash equal to 101% of the principal amount thereof on the date of
      purchase, plus accrued and unpaid interest, if any, to the date of
      purchase (subject to the right of Holders of record on the relevant record
      date to receive interest on the relevant interest payment date);

            (2) the circumstances and relevant facts regarding such Change of
      Control (including information with respect to pro forma historical
      income, cash flow and capitalization, in each case after giving effect to
      such Change of Control);

            (3) the purchase date (which shall be no earlier than 30 days nor
      later than 60 days from the date such notice is mailed); and

            (4) the instructions, as determined by the Company, consistent with
      this Section, that a Holder must follow in order to have its Securities
      purchased.

            (c) Holders electing to have a Security purchased shall be required
to surrender the Security, with an appropriate form duly completed, to the
Company at the address specified in the notice at least three Business Days
prior to the purchase date. Holders shall be entitled to withdraw their election
if the Trustee or the Company receives not later than one Business Day prior to
the purchase date, a telegram, telex, facsimile transmission or letter setting
forth the name of the Holder, the principal amount of the Security which was
delivered for purchase by the Holder and a statement that such Holder is
withdrawing his election to have such Security purchased.

            (d) On the purchase date, all Securities purchased by the Company
under this Section shall be delivered by the Company to the Trustee for
cancellation, and the Company shall pay the purchase price plus accrued and
unpaid interest, if any, to the Holders entitled thereto.

            (e) Notwithstanding the foregoing provisions of this Section, the
Company shall not be required to make a Change of Control Offer following 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 applicable to a Change of Control Offer made by the Company and
purchases all Securities validly tendered and not withdrawn under such Change of
Control Offer.

            (f) The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities laws
or regulations in connection with the purchase of Securities pursuant to this
Section. To the extent that the provisions of any securities laws or regulations
conflict with provisions of this Section, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under this Section by virtue of its compliance with
such securities laws or regulations.

            SECTION 4.11. Limitation on Liens. The Company shall not, and shall
not permit any Restricted Subsidiary to, directly or indirectly, Incur or permit
to exist any Lien (the "Initial Lien") of any nature whatsoever on any of its
properties that are

<PAGE>

                                                                              50

included as Collateral (including Capital Stock of a Restricted Subsidiary), to
secure Indebtedness other than Liens securing First-Priority Lien Obligations,
Liens securing the Securities and any Refinancings thereof and other Permitted
Liens.

            The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, Incur or permit to exist any Initial Lien
of any nature whatsoever on any of its properties that are not included as
Collateral (including Capital Stock of a Restricted Subsidiary), whether owned
at the Issue Date or thereafter acquired, securing any Indebtedness, other than
Permitted Liens, without effectively providing that the Securities shall be
secured equally and ratably with (or prior to, in the case of Subordinated
Obligations) the obligations so secured for so long as such obligations are so
secured.

            Any Lien created for the benefit of the Holders of the Securities
pursuant to the preceding sentence shall provide by its terms that such Lien
shall be automatically and unconditionally released and discharged upon the
release and discharge of the Initial Lien.

            SECTION 4.12. Limitation on Sale/Leaseback Transactions. The Company
shall not, and shall not permit any Restricted Subsidiary to, enter into any
Sale/Leaseback Transaction with respect to any property unless (a) the Company
or such Restricted Subsidiary would be entitled to (1) Incur Indebtedness in an
amount equal to the Attributable Debt with respect to such Sale/Leaseback
Transaction pursuant to Section 4.03 and (2) create a Lien on such property
securing such Attributable Debt without equally and ratably securing the
Securities pursuant to Section 4.11, (b) the net proceeds received by the
Company or any Restricted Subsidiary in connection with such Sale/Leaseback
Transaction are at least equal to the fair market value (as determined by the
Board of Directors) of such property and (c) the Company applies the proceeds of
such transaction in compliance with Section 4.06.

            SECTION 4.13. Future Guarantors. The Company shall cause each
domestic Subsidiary to, and each Foreign Subsidiary that enters into a Guarantee
of any Indebtedness of the Company or a Restricted Subsidiary (other than a
Foreign Subsidiary that Guarantees Indebtedness Incurred by another Foreign
Subsidiary) to, in each case, at the same time that such Guarantee is entered
into, execute and deliver to the Trustee a Guarantee Agreement pursuant to which
such Restricted Subsidiary shall Guarantee payment of the Securities on the same
terms and conditions as those set forth in Article 10 of this Indenture.

            SECTION 4.14. Compliance Certificate. The Company shall deliver to
the Trustee within 120 days after the end of each fiscal year of the Company an
Officers' Certificate stating that in the course of the performance by the
signers of their duties as Officers of the Company they would normally have
knowledge of any Default and whether or not the signers know of any Default that

                                                                              51

            SECTION 4.15. Further Instruments and Acts. Upon request of the

            SECTION 4.16. Intentionally Omitted.

            SECTION 4.17. Impairment of Security Interest. The Company shall
not, and the Company shall not permit any of its Restricted Subsidiaries to,
take or knowingly or negligently omit to take, any action which action or
omission might or would have the result of materially impairing the security
interest with respect to the Collateral for the benefit of the Trustee and the
holders of the Securities.

            SECTION 4.18. Maintenance of Minimum Credit Facility Coverage Ratio.
The Company shall not permit the Credit Facility Coverage Ratio, measured on the
dates on which the Company is required to deliver financial statements under the
Credit Facility as in effect on the Issue Date with respect to each fiscal
quarter commencing with the fiscal quarter ending on December 31, 2004, to be
less than 1.75 to 1.00.

            SECTION 4.19. Excess Cash Flow. (a) Within 120 days after the end of
each Excess Cash Flow Period, the Company shall, unless a default shall have
occurred and be continuing under the Credit Agreement (in which case the
obligations set forth in this Section shall apply once such default is cured or
waived without regard to whether it is cured or waived after such 120 day
period), make an offer to all Holders to purchase Securities using an amount
equal to the Excess Cash Flow Amount pursuant to an Excess Cash Flow Offer (as
defined below).

            Each offer to purchase Securities pursuant to this section (each, an
"Excess Cash Flow Offer") shall be made to each Holder at the time of such
offer, shall offer to purchase Securities at a purchase price equal to the
lesser of (i) 104% and (ii) the then applicable redemption price set forth in
paragraph 5 of the reverse side of the Securities, in each case, of their
principal amount and shall remain open for a period of not less than 20 Business
Days (or any longer period as is required by law).

            (b) If the Company is required to make an Excess Cash Flow Offer
pursuant to this section, no later than 120 days (or such later time as a
default has been cured or waived after such 120 day period in accordance with
the circumstances described above in Section 4.19(a)) after the end of the
applicable Excess Cash Flow Period, the Company shall mail a notice of such
Excess Cash Flow Offer to each Holder stating:

            (i) that the Company is offering to use an amount equal to the
      Excess Cash Flow Amount to purchase Securities at a purchase price in cash
      equal to the lesser of (i) 104% and (ii) the then applicable redemption
      price set forth in paragraph 5 of the reverse side of the Securities, in
      each case, of their principal amount on the date of purchase, plus accrued
      and unpaid interest, if any, to the date of purchase
<PAGE>

                                                                              52

      (without duplication, subject to the right of Holders of record on the
      relevant record date to receive interest on the relevant interest payment
      date);

            (ii) the purchase date (which shall be no earlier than 30 days nor
      later than 60 days from the date such notice is mailed); and

            (iii) the instructions, as determined by the Company, consistent
      with this Section 4.19, that a Holder must follow in order to tender its
      Securities.

            (c) If the aggregate purchase price (exclusive of accrued and unpaid
interest) of the Securities tendered in connection with any Excess Cash Flow
Offer exceeds the Excess Cash Flow Amount allotted to their purchase, the
Trustee shall select the Securities to be purchased on a pro rata basis but in
denominations of $1,000 principal amount or multiples thereof. If the aggregate
purchase price of the Securities tendered in connection with any Excess Cash
Flow Offer is less than the Excess Cash Flow Amount allotted to their purchase,
the Company shall be permitted to use the portion of the Excess Cash Flow Amount
that is not applied to the purchase of Securities in connection with such Excess
Cash Flow Offer for general corporate purposes or for any other purposes not
prohibited by this Indenture. To the extent the Excess Cash Flow Amount for any
Excess Cash Flow Period is less than $5.0 million, the Company may elect not to
make an Excess Cash Flow Offer for such Excess Cash Flow Period and, in lieu
thereof add such Excess Cash Flow to the amount of Excess Cash Flow for the next
succeeding Excess Cash Flow Period. Upon completion of an Excess Cash Flow
Offer, the Excess Cash Flow Amount with respect thereto shall be deemed to be
reduced by the aggregate amount of such Excess Cash Flow Offer.

            (d) 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 in connection with the
repurchase of Securities pursuant to an Excess Cash Flow Offer. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions of this Section 4.19, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 4.19 by virtue of its compliance with such
securities laws or regulations.

            SECTION 4.20. After-Acquired Property. Upon the acquisition by the
Company or any Subsidiary Guarantor of any First-Priority After-Acquired
Property, the Company or such Subsidiary Guarantor shall execute and deliver
such mortgages, deeds of trust, security instruments, financing statements and
certificates and opinions of counsel as shall be reasonably necessary to vest in
the Trustee a perfected security interest, subject only to Permitted Liens, in
such First-Priority After-Acquired Property and to have such First-Priority
After-Acquired Property added to the Collateral, and thereupon all provisions of
this Indenture relating to the Collateral shall be deemed to relate to such
First-Priority After-Acquired Property to the same extent and with the same
force and effect; provided, however, that if granting such second-priority
security interest in such First-Priority After-Acquired Property requires the
consent of a third party, the Company shall use commercially reasonable efforts
to obtain such consent with respect

<PAGE>

                                                                              53

to the second-priority interest for the benefit of the Trustee on behalf of the
Holders; provided further, however, that if such third party does not consent to
the granting of such second-priority security interest after the use of such
commercially reasonable efforts, the Company or such Subsidiary Guarantor, as
the case may be, shall not be required to provide such security interest.

                                   ARTICLE 5

                               Successor Company

            SECTION 5.01. When Company May Merge or Transfer Assets. (a) The
Company shall not consolidate with or merge with or into, or convey, transfer or
lease, in one transaction or a series of transactions, directly or indirectly,
all or substantially all its assets to, any Person, unless:

            (1) the resulting, surviving or transferee Person (the "Successor
      Company") shall be a Person organized and existing under the laws of the
      United States of America, any State thereof or the District of Columbia
      and the Successor Company (if not the Company) shall expressly assume, by
      an indenture supplemental thereto, executed and delivered to the Trustee,
      in form satisfactory to the Trustee, all the obligations of the Company
      under the Securities and this Indenture;

            (2) immediately after giving pro forma effect to such transaction
      (and treating any Indebtedness which becomes an obligation of the
      Successor Company or any Subsidiary as a result of such transaction as
      having been Incurred by such Successor Company or such Subsidiary at the
      time of such transaction), no Default shall have occurred and be
      continuing;

            (3) immediately after giving pro forma effect to such transaction,
      the Successor Company would be able to Incur an additional $1.00 of
      Indebtedness pursuant to Section 4.03(a); and

            (4) the Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that such
      consolidation, merger or transfer and such supplemental indenture (if any)
      comply with this Indenture;

provided, however, that clause (3) shall not be applicable to (A) a Restricted
Subsidiary consolidating with, merging into or transferring all or part of its
properties and assets to the Company (so long as no Capital Stock of the Company
is distributed to any Person) or another Subsidiary Guarantor that is a Wholly
Owned Subsidiary or (B) the Company merging with an Affiliate of the Company
solely for the purpose and with the sole effect of reincorporating the Company
in another jurisdiction.

            For purposes of this Section 5.01, the sale, lease, conveyance,
assignment, transfer or other disposition of all or substantially all of the
properties and assets of one or

<PAGE>

                                                                              54

more Subsidiaries of the Company, which properties and assets, if held by the
Company instead of such Subsidiaries, would constitute all or substantially all
of the properties and assets of the Company on a consolidated basis, shall be
deemed to be the transfer of all or substantially all of the properties and
assets of the Company.

            The Successor Company shall be the successor to the Company and
shall succeed to, and be substituted for, and may exercise every right and power
of, the Company under this Indenture, and the predecessor Company, except in the
case of a lease, shall be released from the obligation to pay the principal of
and interest on the Securities.

            (b) The Company shall not permit any Subsidiary Guarantor to
consolidate with or merge with or into, or convey, transfer or lease, in one
transaction or series of transactions, all or substantially all of its assets to
any Person unless:

            (1) the resulting, surviving or transferee Person (if not such
      Subsidiary) shall be a Person organized and existing under the laws of the
      jurisdiction under which such Subsidiary was organized or under the laws
      of the United States of America, or any State thereof or the District of
      Columbia, and such Person shall expressly assume, by a Guarantee
      Agreement, in a form satisfactory to the Trustee, all the obligations of
      such Subsidiary, if any, under its Subsidiary Guarantee; provided,
      however, that the foregoing shall not apply in the case of a Subsidiary
      Guarantor (other than T-Netix and Evercom) (A) that has been disposed of
      in its entirety to another Person (other than to the Company or an
      Affiliate of the Company), whether through a merger, consolidation or sale
      of Capital Stock or assets or (B) that, as a result of the disposition of
      all or a portion of its Capital Stock, ceases to be a Subsidiary, in both
      cases, if in connection therewith the Company provides an Officers'
      Certificate to the Trustee to the effect that the Company shall comply
      with its obligations under Section 4.06 in respect of such disposition;

            (2) immediately after giving effect to such transaction or
      transactions on a pro forma basis (and treating any Indebtedness which
      becomes an obligation of the resulting, surviving or transferee Person as
      a result of such transaction as having been issued by such Person at the
      time of such transaction), no Default shall have occurred and be
      continuing; and

            (3) the Company delivers to the Trustee an Officers' Certificate and
      an Opinion of Counsel, each stating that such consolidation, merger or
      transfer and such Guarantee Agreement, if any, complies with this
      Indenture.

      the satisfaction in full of all obligations under this Indenture and
      discharge of the Indenture or any security interest created hereunder and
      under the Security Documents shall be declared invalid or unenforceable
      (other than security interests that are (i) not material with respect to
      the Collateral taken as a whole and (ii) subsequently declared valid and
      enforceable within 10 days of such declaration of the invalidity or
      unenforceability of such security interest) or the Company or any
      Subsidiary Guarantor shall assert, in any pleading in any court of
      competent jurisdiction, that any such security interest is invalid or
      unenforceable.

            The foregoing shall constitute Events of Default whatever the reason
for any such Event of Default and whether it is voluntary or involuntary or is
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body.

            The term "Bankruptcy Law" means Title 11, United States Code, or any
similar Federal or state law for the relief of debtors. The term "Custodian"
means any

<PAGE>

                                                                              57

receiver, trustee, assignee, liquidator, custodian or similar official
under any Bankruptcy Law.

            A Default under clauses (4), (5) or (6) is not an Event of Default
until the Trustee or the holders of at least 25% in principal amount of the
outstanding Securities notify the Company of the Default and the Company does
not cure such Default within the time specified after receipt of such notice.
Such notice must specify the Default, demand that it be remedied and state that
such notice is a "Notice of Default".

            The Company shall deliver to the Trustee, within 30 days after the
occurrence thereof, written notice in the form of an Officers' Certificate of
any Event of Default under clause (7), (11) or (12) and any event which with the
giving of notice or the lapse of time would become an Event of Default under
clause (4), (5), (6), (9) or (10), its status and what action the Company is
taking or proposes to take with respect thereto.

            SECTION 6.02. Acceleration. If an Event of Default (other than an
Event of Default specified in Section 6.01(8) or (9) with respect to the
Company) occurs and is continuing, the Trustee by notice to the Company, or the
Holders of at least 25% in principal amount of the Securities by notice to the
Company and the Trustee, may declare the principal of and accrued but unpaid
interest on all the Securities to be due and payable. Upon such a declaration,
such principal and interest shall be due and payable immediately. If an Event of
Default specified in Section 6.01(8) or (9) with respect to the Company occurs,
the principal of and interest on all the Securities shall ipso facto become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Securityholders. The Holders of a majority in principal
amount of the Securities by notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or
decree and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of
acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.

            SECTION 6.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any available remedy to collect the payment
of principal of or interest on the Securities or to enforce the performance of
any provision of the Securities or this Indenture.

            The Trustee may maintain a proceeding even if it does not possess
any of the Securities or does not produce any of them in the proceeding. A delay
or omission by the Trustee or any Securityholder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

            SECTION 6.04. Waiver of Past Defaults. The Holders of a majority in
principal amount of the Securities by notice to the Trustee may waive an
existing Default and its consequences except (a) a Default in the payment of the
principal of or interest on a Security, (b) a Default arising from the failure
to redeem or purchase any Security when

<PAGE>

                                                                              58

required pursuant to this Indenture or (c) a Default in respect of a provision
that under Section 9.02 cannot be amended without the consent of each
Securityholder affected. When a Default is waived, it is deemed cured, but no
such waiver shall extend to any subsequent or other Default or impair any
consequent right.

            SECTION 6.05. Control by Majority. The Holders of a majority in
principal amount of the Securities may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 7.01, that the Trustee determines is unduly prejudicial to
the rights of other Securityholders or would involve the Trustee in personal
liability; provided, however, that the Trustee may take any other action deemed
proper by the Trustee that is not inconsistent with such direction. Prior to
taking any action hereunder, the Trustee shall be entitled to indemnification
satisfactory to it in its sole discretion against all losses and expenses caused
by taking or not taking such action.

            SECTION 6.06. Limitation on Suits. Except to enforce the right to
receive payment of principal, premium (if any) or interest when due, no
Securityholder may pursue any remedy with respect to this Indenture or the
Securities unless:

            (1) the Holder gives to the Trustee written notice stating that an
      Event of Default is continuing;

            (2) the Holders of at least 25% in principal amount of the
      Securities make a written request to the Trustee to pursue the remedy;

            (3) such Holder or Holders offer to the Trustee security or
      indemnity reasonably satisfactory to it against any loss, liability or
      expense;

            (4) the Trustee does not comply with the request within 60 days
      after receipt of the request and the offer of security or indemnity; and

            (5) the Holders of a majority in principal amount of the Securities
      do not give the Trustee a direction inconsistent with the request during
      such 60-day period.

            A Securityholder may not use this Indenture to prejudice the rights
of another Securityholder or to obtain a preference or priority over another
Securityholder. In the event that the Definitive Securities are not issued to
any beneficial owner promptly after the Registrar has received a request from
the Holder of a Global Security to issue such Definitive Securities to such
beneficial owner of its nominee, the Company expressly agrees and acknowledges,
with respect to the right of any Holder to pursue a remedy pursuant to this
Indenture, the right of such beneficial holder of Securities to pursue such
remedy with respect to the portion of the Global Security that represents such
beneficial holder's Securities as if such Definitive Securities had been issued.

            SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding
any other provision of this Indenture, the right of any Holder to receive
payment of principal of and interest on the Securities held by such Holder, on
or after the respective due dates expressed in the Securities, or to bring suit
for the enforcement of any such payment on or after such respective dates, shall
not be impaired or affected without the consent of such Holder.

            SECTION 6.08. Collection Suit by Trustee. If an Event of Default
specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount then due and owing (together with interest on any
unpaid interest to the extent lawful) and the amounts provided for in Section
7.07.

            SECTION 6.09. Trustee May File Proofs of Claim. The Trustee may file
such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Securityholders
allowed in any judicial proceedings relative to the Company, its creditors or
its property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Holders in any election of a trustee in bankruptcy or other
Person performing similar functions, and any Custodian in any such judicial
proceeding is hereby authorized by each Holder to make payments to the Trustee
and, in the event that the Trustee shall consent to the making of such payments
directly to the Holders, to pay to the Trustee any amount due it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and its counsel, and any other amounts due the Trustee under Section
7.07.

            Priorities. If the Trustee collects any money or property pursuant
      to this Article 6, it shall pay out the money or property in the following
      order:

            FIRST: to the Trustee for amounts due under Section 7.07;

            SECOND: to Securityholders for amounts due and unpaid on the
      Securities for principal and interest, ratably, without preference or
      priority of any kind, according to the amounts due and payable on the
      Securities for principal and interest, respectively; and

            THIRD: to the Company.

            The Trustee may fix a record date and payment date for any payment
to Securityholders pursuant to this Section At least 15 days before such record
date, the Company shall mail to each Securityholder and the Trustee a notice
that states the record date, the payment date and amount to be paid.

            SECTION 6.10. Undertaking for Costs. In any suit for the enforcement
of any right or remedy under this Indenture or in any suit against the Trustee
for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good

<PAGE>

                                                                              60

faith of the claims or defenses made by the party litigant. This Section does
not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07
or a suit by Holders of more than 10% in aggregate principal amount of the
Securities.

            SECTION 6.11. Waiver of Stay or Extension Laws. The Company (to the
extent it may lawfully do so) shall not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and the Company (to
the extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law, and shall not hinder, delay or impede the execution
of any power herein granted to the Trustee, but shall suffer and permit the
execution of every such power as though no such law had been enacted.

                                   ARTICLE 7

                                    Trustee

            SECTION 7.01. Duties of Trustee. (a) If an Event of Default has
occurred and is continuing, the Trustee shall exercise the rights and powers
vested in it by this Indenture and use the same degree of care and skill in
their exercise as a prudent Person would exercise or use under the circumstances
in the conduct of such Person's own affairs.

            (b) Except during the continuance of an Event of Default:

            (1) the Trustee undertakes to perform such duties and only such
      duties as are specifically set forth in this Indenture and no implied
      covenants or obligations shall be read into this Indenture against the
      Trustee; and

            (2) in the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, in the case of certificates or opinions specifically required by
      any provision hereof to be furnished to it, the Trustee shall examine the
      certificates and opinions to determine whether or not they conform to the
      requirements of this Indenture.

            (c) The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own wilful misconduct,
except that:

      this Section;

            (2) the Trustee shall not be liable for any error of judgment made
      in good faith by a Trust Officer unless it is proved that the Trustee was

expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

            (h) Every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

            SECTION 7.02. Rights of Trustee. (a) The Trustee may conclusively

profit) irrespective of whether the Trustee has been advised of the likelihood
of such loss or damage and regardless of the form of action.

            (g) The Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee has actual

            (h) The rights, privileges, protections, immunities and benefits

Trustee against the costs, expenses and liabilities which might be incurred by
it in compliance with such request or direction.

            SECTION 7.03. Individual Rights of Trustee. The Trustee in its
individual or any other capacity may become the owner or pledgee of Securities
and may otherwise deal with the Company or its Affiliates with the same rights
it would have if it were not Trustee. Any Paying Agent, Registrar, co-registrar

comply with Sections 7.10 and 7.11.

<PAGE>

                                                                              63

and so long as a committee of its Trust Officers in good faith determines that
withholding the notice is not opposed to the interests of the Securityholders.

            SECTION 7.06. Reports by Trustee to Holders. As promptly as
practicable after each August 1 beginning with the August 1 following the date
of this Indenture, and in any event prior to October 1 in each year, the Trustee

the Trustee from time to time reasonable compensation for its services. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred or made by it,
including costs of collection, in addition to the compensation for its services.
Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Trustee's agents, counsel, accountants and
experts. The Company and the Subsidiary Guarantors, jointly and severally, shall
indemnify the Trustee against any and all loss, liability or expense (including
attorneys' fees and expenses) incurred by it in connection with the
administration of this trust (including under the Security Documents) and the
performance of its duties hereunder. The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity. Failure by the Trustee to
so notify the Company shall not relieve the Company of its obligations
hereunder. The Company shall defend the claim and the Trustee may have separate
counsel and the Company shall pay the fees and expenses of such counsel. The
Company need not reimburse any expense or indemnify against any loss, liability
or expense incurred by the Trustee through the Trustee's own wilful misconduct,
negligence or bad faith.

            To secure the Company's payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.

            The Company's payment obligations pursuant to this Section shall
survive the discharge of this Indenture. When the Trustee incurs expenses after
the occurrence of a Default specified in Section 6.01(7) or (8) with respect to
the Company, the expenses are intended to constitute expenses of administration
under the Bankruptcy Law.

            SECTION 7.08. Replacement of Trustee. The Trustee may resign at any
time by so notifying the Company. The Holders of a majority in principal amount
of the Securities may remove the Trustee by so notifying the Trustee and may
appoint a successor Trustee. The Company shall remove the Trustee if:

<PAGE>

                                                                              64

            (1) the Trustee fails to comply with Section 7.10;

            (2) the Trustee is adjudged bankrupt or insolvent;

            (3) a receiver or other public officer takes charge of the Trustee
      or its property; or

            (4) the Trustee otherwise becomes incapable of acting.

            If the Trustee resigns, is removed by the Company or by the Holders
of a majority in principal amount of the Securities and such Holders do not
reasonably promptly appoint a successor Trustee, or if a vacancy exists in the
office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Company shall promptly appoint a successor
Trustee.

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Securityholders. The retiring Trustee shall promptly transfer all
property held by it as Trustee to the successor Trustee, subject to the lien
provided for in Section 7.07.

            If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, at the expense of
the Company, or the Holders of 10% in principal amount of the Securities, at
their own expense, may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

            If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

            Notwithstanding the replacement of the Trustee pursuant to this
Section, the Company's obligations under Section 7.07 shall continue for the
benefit of the retiring Trustee.

            SECTION 7.09. Successor Trustee by Merger. If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

            In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of the
successor to the

                                                                              65

Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Securities or in this Indenture provided that the
certificate of the Trustee shall have.

            SECTION 7.10. Eligibility; Disqualification. The Trustee shall at
all times satisfy the requirements of TIA Section 310(a). The Trustee shall
have a combined capital and surplus of at least $50,000,000 as set forth in its
most recent published annual report of condition. The Trustee shall comply with
TIA Section 310(b); provided, however, that there shall be excluded from the
operation of TIA Section 310(b)(1) any indenture or indentures under which
other securities or certificates of interest or participation in other
securities of the Company are outstanding if the requirements for such exclusion
set forth in TIA Section 310(b)(1) are met.

            SECTION 7.11. Preferential Collection of Claims Against Company. The
Trustee shall comply with TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated.

                                   ARTICLE 8

                       Discharge of Indenture; Defeasance

            SECTION 8.01. Discharge of Liability on Securities; Defeasance. (a)
When (1) the Company delivers to the Trustee all outstanding Securities (other
than Securities replaced pursuant to Section 2.07) for cancellation or (2) all
outstanding Securities have become due and payable, whether at maturity or as a
result of the mailing of a notice of redemption pursuant to Article 3 hereof and
the Company irrevocably deposits with the Trustee funds sufficient to pay at
maturity or upon redemption all outstanding Securities, including interest
thereon to maturity or such redemption date (other than Securities replaced
pursuant to Section 2.07), and if in either case the Company pays all other sums
payable hereunder by the Company, then this Indenture shall, subject to Section
8.01(c), cease to be of further effect. The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of the Company
accompanied by an Officers' Certificate and an Opinion of Counsel and at the
cost and expense of the Company.

            (b) Subject to Sections 8.01(c) and 8.02, the Company at any time
may terminate (1) all its obligations under the Securities, this Indenture and
the Security Documents ("legal defeasance option") or (2) its obligations under
Sections 4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13,
4.17, 4.18 and 4.19 and the operation of Sections 6.01(4), 6.01(7), 6.01(8),
6.01(9), 6.01(10), 6.01(11) and 6.01(12) (but, in the case of Sections 6.01(8)
and (9), with respect only to Significant Subsidiaries and Subsidiary
Guarantors) and the limitations contained in Section 5.01(a)(3) ("covenant
defeasance option"). The Company may exercise its legal defeasance option
notwithstanding its prior exercise of its covenant defeasance option.

<PAGE>

                                                                              66

            If the Company exercises its legal defeasance option, payment of the
Securities may not be accelerated because of an Event of Default with respect
thereto. If the Company exercises its covenant defeasance option, payment of the
Securities may not be accelerated because of an Event of Default specified in
Sections 6.01(4), 6.01(7), 6.01(8), 6.01(9), 6.01(10), 6.01(11) and 6.01(12)
(but, in the case of Sections 6.01(8) and (9), with respect only to Significant
Subsidiaries and Subsidiary Guarantors) or because of the failure of the Company
to comply with Section 5.01(a)(3). If the Company exercises its legal defeasance
option or its covenant defeasance option, each Subsidiary Guarantor, if any,
shall be released from all its obligations with respect to its Subsidiary
Guarantee and the Security Documents.

            Upon satisfaction of the conditions set forth herein and upon
request of the Company, the Trustee shall acknowledge in writing the discharge
of those obligations that the Company terminates.

            (c) Notwithstanding clauses (a) and (b) above, the Company's
obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 and in
this Article 8 shall survive until the Securities have been paid in full.
Thereafter, the Company's obligations in Sections 7.07, 8.04 and 8.05 shall
survive such satisfaction and discharge.

            SECTION 8.02. Conditions to Defeasance. The Company may exercise its
legal defeasance option or its covenant defeasance option only if:

            (1) the Company irrevocably deposits in trust with the Trustee money
      or U.S. Government Obligations for the payment of principal of and
      interest on the Securities to maturity or redemption, as the case may be;

            (2) the Company delivers to the Trustee a certificate from a
      nationally recognized firm of independent accountants expressing their
      opinion that the payments of principal and interest when due and without
      reinvestment on the deposited U.S. Government Obligations plus any
      deposited money without investment shall provide cash at such times and in
      such amounts as shall be sufficient to pay principal and interest when due
      on all the Securities to maturity or redemption, as the case may be;

            (3) 123 days pass after the deposit is made and during the 123-day
      period no Default specified in Sections 6.01(8) or (9) with respect to the
      Company occurs which is continuing at the end of the period;

            (4) the deposit does not constitute a default under any other
      agreement binding on the Company;

            (5) the Company delivers to the Trustee an Opinion of Counsel to the
      effect that the trust resulting from the deposit does not constitute, or
      is qualified as, a regulated investment company under the Investment
      Company Act of 1940;

            (6) in the case of the legal defeasance option, the Company shall
      have delivered to the Trustee an Opinion of Counsel stating that (A) the
      Company has

<PAGE>

                                                                              67

      received from, or there has been published by, the Internal Revenue
      Service a ruling, or (B) since the date of this Indenture there has been a
      change in the applicable Federal income tax law, in either case to the
      effect that, and based thereon such Opinion of Counsel shall confirm that,
      the Securityholders shall not recognize income, gain or loss for Federal
      income tax purposes as a result of such defeasance and shall be subject to
      Federal income tax on the same amounts, in the same manner and at the same
      times as would have been the case if such defeasance had not occurred;

            (7) in the case of the covenant defeasance option, the Company shall
      have delivered to the Trustee an Opinion of Counsel to the effect that the
      Securityholders shall not recognize income, gain or loss for Federal
      income tax purposes as a result of such covenant defeasance and shall be
      subject to Federal income tax on the same amounts, in the same manner and
      at the same times as would have been the case if such covenant defeasance
      had not occurred; and

            (8) the Company delivers to the Trustee an Officers' Certificate and
      an Opinion of Counsel, each stating that all conditions precedent to the
      defeasance and discharge of the Securities as contemplated by this Article
      8 have been complied with.

            Before or after a deposit, the Company may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date in
accordance with Article 3.

            SECTION 8.03. Application of Trust Money. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this
Article 8. It shall apply the deposited money and the money from U.S. Government
Obligations through the Paying Agent and in accordance with this Indenture to
the payment of principal of and interest on the Securities.

            SECTION 8.04. Repayment to Company. The Trustee and the Paying Agent
shall promptly turn over to the Company upon request any excess money or
securities held by them at any time.

            Subject to any applicable abandoned property law, the Trustee and
the Paying Agent shall pay to the Company upon request any money held by them
for the payment of principal or interest that remains unclaimed for two years,
and, thereafter, Securityholders entitled to the money must look to the Company
for payment as general creditors.

            SECTION 8.05. Indemnity for Government Obligations. The Company
shall pay and shall indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against deposited U.S. Government Obligations or the
principal and interest received on such U.S. Government Obligations.

            SECTION 8.06. Reinstatement. If the Trustee or Paying Agent is
unable to apply any money or U.S. Government Obligations in accordance with this
Article 8 by

<PAGE>

                                                                              68

reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Company's and each Subsidiary Guarantor's obligations
under this Indenture, each Subsidiary Guarantee and the Securities shall be
revived and reinstated as though no deposit had occurred pursuant to this
Article 8 until such time as the Trustee or Paying Agent is permitted to apply
all such money or U.S. Government Obligations in accordance with this Article 8;
provided, however, that, if the Company has made any payment of interest on or
principal of any Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the money or U.S. Government Obligations held by the
Trustee or Paying Agent.

                                   ARTICLE 9

                                   Amendments

            SECTION 9.01. Without Consent of Holders. The Company, the
Subsidiary Guarantors and the Trustee may amend this Indenture, the Securities
or the Security Documents without notice to or consent of any Securityholder:

            (1) to cure any ambiguity, omission, defect or inconsistency;

            (2) to comply with Article 5;

            (3) to provide for uncertificated Securities in addition to or in
      place of certificated Securities; provided, however, that the
      uncertificated Securities are issued in registered form for purposes of
      Section 163(f) of the Code or in a manner such that the uncertificated
      Securities are described in Section 163(f)(2)(B) of the Code;

            (4) to add Guarantees with respect to the Securities, including any
      Subsidiary Guaranties, or to provide further security for the Securities;

            (5) to add to the covenants of the Company or any Subsidiary
      Guarantor for the benefit of the Holders or to surrender any right or
      power herein conferred upon the Company or any Subsidiary Guarantor;

            (6) to comply with any requirement of the SEC in connection with
      qualifying, or maintaining the qualification of, this Indenture under the
      TIA;

            (7) to make any change that does not adversely affect the rights of
      any Securityholder;

            (8) to make any amendment to the provisions of this Indenture
      relating to the transfer and legending of Securities; provided, however,
      that (a) compliance with this Indenture as so amended would not result in
      Securities being transferred in violation of the Securities Act or any
      other applicable securities law and

<PAGE>

                                                                              69

      (b) such amendment does not materially and adversely affect the rights of
      Holders to transfer Securities; or

            (9) in the event that such amendment is expressly permitted pursuant
      to Section 11.01(b) or pursuant to the Security Documents.

            After an amendment under this Section becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section

            SECTION 9.02. With Consent of Holders. The Company, the Subsidiary
Guarantors and the Trustee may amend this Indenture or the Securities with the
written consent of the Holders of at least a majority in principal amount of the
Securities then outstanding (including consents obtained in connection with a
tender offer or exchange for the Securities) and any past default or compliance
with any provisions may also be waived with the consent of the Holders of at
least a majority in principal amount of the Securities then outstanding.
However, without the consent of each Securityholder affected thereby, an
amendment or waiver may not:

            (1) reduce the amount of Securities whose Holders must consent to an
      amendment;

            (2) reduce the rate of or extend the time for payment of interest on
      any Security;

            (3) reduce the principal of or change the Stated Maturity of any
      Security;

            (4) change the provisions applicable to the redemption of any
      Security contained in Article 3 hereto or paragraph 5 of the Securities;

            (5) make any Security payable in money other than that stated in the
      Security;

            (6) make any changes in the ranking or priority of any Security that
      would adversely affect the Securityholders;

            (7) make any change in Section 6.04 or 6.07 or the second sentence
      of this Section;

            (8) make any change in, or release other than in accordance with
      this Indenture, any Subsidiary Guarantee that would adversely affect the
      Securityholders; or

            (9) make any change in any Security Document or the provisions of
      this Indenture relating to the Security Documents or the application of
      proceeds of the Collateral, or release Collateral from the Lien pursuant
      to this Indenture in the

<PAGE>

                                                                              70

      event that such change would adversely affect the Securityholders,
      provided that such change is not otherwise expressly permitted without the
      consent of each Securityholder affected thereby pursuant to Section
      11.01(b) or pursuant to the Security Documents.

            It shall not be necessary for the consent of the Holders under this
Section to approve the particular form of any proposed amendment, but it shall
be sufficient if such consent approves the substance thereof.

            After an amendment under this Section becomes effective, the Company
shall mail to Securityholders a notice briefly describing such amendment. The
failure to give such notice to all Securityholders, or any defect therein, shall
not impair or affect the validity of an amendment under this Section

            SECTION 9.03. Compliance with Trust Indenture Act. Every amendment
to this Indenture or the Securities shall comply with the TIA as then in effect.

            SECTION 9.04. Revocation and Effect of Consents and Waivers. A
consent to an amendment or a waiver by a Holder of a Security shall bind the
Holder and every subsequent Holder of that Security or portion of the Security
that evidences the same debt as the consenting Holder's Security, even if
notation of the consent or waiver is not made on the Security. However, any such
Holder or subsequent Holder may revoke the consent or waiver as to such Holder's
Security or portion of the Security if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an
amendment or waiver becomes effective, it shall bind every Securityholder. An
amendment or waiver becomes effective upon the execution of such amendment or
waiver by the Trustee.

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Securityholders entitled to give their
consent or take any other action described above or required or permitted to be
taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding the immediately preceding paragraph, those Persons who were
Securityholders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent
previously given or to take any such action, whether or not such Persons
continue to be Holders after such record date. No such consent shall be valid or
effective for more than 120 days after such record date.

            SECTION 9.05. Notation on or Exchange of Securities. If an amendment
changes the terms of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate
notation on the Security regarding the changed terms and return it to the
Holder. Alternatively, if the Company or the Trustee so determines, the Company
in exchange for the Security shall issue and the Trustee shall authenticate a
new Security that reflects the changed terms. Failure to make the appropriate
notation or to issue a new Security shall not affect the validity of such
amendment.

                                                                              71

            SECTION 9.06. Trustee To Sign Amendments. The Trustee shall sign any
amendment authorized pursuant to this Article 9 if the amendment does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may but need not sign it. In signing such amendment the
Trustee shall be entitled to receive indemnity reasonably satisfactory to it and
shall be provided with by the Company, and (subject to Section 7.01) shall be
fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel stating that such amendment is authorized or permitted by this
Indenture.

            SECTION 9.07. Payment for Consent. Neither the Company nor any
Affiliate of the Company shall, directly or indirectly, pay or cause to be paid
any consideration, whether by way of interest, fee or otherwise, to any Holder
for or as an inducement to any consent, waiver or amendment of any of the terms
or provisions of this Indenture or the Securities unless such consideration is
offered to all Holders and is paid to all Holders that so consent, waive or
agree to amend in the time frame set forth in solicitation documents relating to
such consent, waiver or agreement.

                                   ARTICLE 10

                              Subsidiary Guaranties

            SECTION 10.01. Guaranties. Each Subsidiary Guarantor hereby
unconditionally and irrevocably guarantees, jointly and severally, to each
Holder and to the Trustee and its successors and assigns (a) the full and
punctual payment of principal of and interest on the Securities when due,
whether at maturity, by acceleration, by redemption or otherwise, and all other
monetary obligations of the Company under this Indenture and the Securities and
(b) the full and punctual performance within applicable grace periods of all
other obligations of the Company under this Indenture and the Securities (all
the foregoing being hereinafter collectively called the "Guaranteed
Obligations"). Each Subsidiary Guarantor further agrees that the Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice or
further assent from such Subsidiary Guarantor and that such Subsidiary Guarantor
shall remain bound under this Article 10 notwithstanding any extension or
renewal of any Obligation.

            Each Subsidiary Guarantor waives presentation to, demand of, payment
from and protest to the Company of any of the Guaranteed Obligations and also
waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice
of any default under the Securities or the Guaranteed Obligations. The
obligations of each Subsidiary Guarantor hereunder shall not be affected by (1)
the failure of any Holder or the Trustee to assert any claim or demand or to
enforce any right or remedy against the Company or any other Person (including
any Subsidiary Guarantor) under this Indenture, the Securities or any other
agreement or otherwise; (2) any extension or renewal of any thereof; (3) any
rescission, waiver, amendment or modification of any of the terms or provisions
of this Indenture, the Securities or any other agreement; (4) the release of any
security held by any Holder or the Trustee for the Guaranteed Obligations or any
of them; (5) the failure of any Holder or the Trustee to exercise any right or
remedy against any

<PAGE>

                                                                              72

other guarantor of the Guaranteed Obligations; or (6) except as set forth in
Section 10.06, any change in the ownership of such Subsidiary Guarantor.

            Each Subsidiary Guarantor further agrees that its Subsidiary
Guarantee herein constitutes a guarantee of payment, performance and compliance
when due (and not a guarantee of collection) and waives any right to require
that any resort be had by any Holder or the Trustee to any security held for
payment of the Guaranteed Obligations.

            Except as expressly set forth in Sections 8.01(b), 10.02 and 10.06,
the obligations of each Subsidiary Guarantor hereunder shall not be subject to
any reduction, limitation, impairment or termination for any reason, including
any claim of waiver, release, surrender, alteration or compromise, and shall not
be subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of the
Guaranteed Obligations or otherwise. Without limiting the generality of the
foregoing, the obligations of each Subsidiary Guarantor herein shall not be
discharged or impaired or otherwise affected by the failure of any Holder or the
Trustee to assert any claim or demand or to enforce any remedy under this
Indenture, the Securities or any other agreement, by any waiver or modification
of any thereof, by any default, failure or delay, willful or otherwise, in the
performance of the obligations, or by any other act or thing or omission or
delay to do any other act or thing which may or might in any manner or to any
extent vary the risk of such Subsidiary Guarantor or would otherwise operate as
a discharge of such Subsidiary Guarantor as a matter of law or equity.

            Each Subsidiary Guarantor further agrees that its Guarantee herein
shall continue to be effective or be reinstated, as the case may be, if at any
time payment, or any part thereof, of principal of or interest on any Obligation
is rescinded or must otherwise be restored by any Holder or the Trustee upon the
bankruptcy or reorganization of the Company or otherwise.

            In furtherance of the foregoing and not in limitation of any other
right which any Holder or the Trustee has at law or in equity against any
Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay
the principal of or interest on any Obligation when and as the same shall become
due, whether at maturity, by acceleration, by redemption or otherwise, or to
perform or comply with any other Obligation, each Subsidiary Guarantor hereby
promises to and shall, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal
to the sum of (A) the unpaid amount of such Guaranteed Obligations, (B) accrued
and unpaid interest on such Guaranteed Obligations (but only to the extent not
prohibited by law) and (C) all other monetary Guaranteed Obligations of the
Company to the Holders and the Trustee.

            Each Subsidiary Guarantor agrees that, as between it, on the one
hand, and the Holders and the Trustee, on the other hand, (i) the maturity of
the Guaranteed Obligations hereby may be accelerated as provided in Article 6
for the purposes of such Subsidiary Guarantor's Subsidiary Guarantee herein,
notwithstanding any stay, injunction

<PAGE>

                                                                              73

or other prohibition preventing such acceleration in respect of the Guaranteed
Obligations guaranteed hereby, and (ii) in the event of any declaration of
acceleration of such Guaranteed Obligations as provided in Article 6, such
Guaranteed Obligations (whether or not due and payable) shall forthwith become
due and payable by such Subsidiary Guarantor for the purposes of this Section

            Each Subsidiary Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section

            SECTION 10.02. Limitation on Liability. Any term or provision of
this Indenture to the contrary notwithstanding, the maximum aggregate amount of
the Guaranteed Obligations guaranteed hereunder by any Subsidiary Guarantor
shall not exceed the maximum amount that can be hereby guaranteed without
rendering this Indenture, as it relates to such Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

            SECTION 10.03. Successors and Assigns. This Article 10 shall be
binding upon each Subsidiary Guarantor and its successors and assigns and shall
enure to the benefit of the successors and assigns of the Trustee and the
Holders and, in the event of any transfer or assignment of rights by any Holder
or the Trustee, the rights and privileges conferred upon that party in this
Indenture and in the Securities shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions of this
Indenture.

            SECTION 10.04. No Waiver. Neither a failure nor a delay on the part
of either the Trustee or the Holders in exercising any right, power or privilege
under this Article 10 shall operate as a waiver thereof, nor shall a single or
partial exercise thereof preclude any other or further exercise of any right,
power or privilege. The rights, remedies and benefits of the Trustee and the
Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 10 at law,
in equity, by statute or otherwise.

            SECTION 10.05. Modification. No modification, amendment or waiver of
any provision of this Article 10, nor the consent to any departure by any
Subsidiary Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice to or demand on any Subsidiary Guarantor in any case shall
entitle such Subsidiary Guarantor to any other or further notice or demand in
the same, similar or other circumstances.

            SECTION 10.06. Release of Subsidiary Guarantor. A Subsidiary
Guarantor shall be released from its obligations under this Article 10 (other
than any obligation that may have arisen under Section 10.07)

            (1) upon the sale (including any sale pursuant to any exercise of
      remedies by a holder of Indebtedness of the Company or of such Subsidiary
      Guarantor) or other disposition (including by way of consolidation or
      merger) of a Subsidiary Guarantor (other than a sale or disposition of
      T-Netix or Evercom),

            (2) upon the sale or disposition of all or substantially all the
      assets of such Subsidiary Guarantor (other than a sale or disposition of
      T-Netix or Evercom),

            (3) upon the designation of such Subsidiary Guarantor (other than
      T-Netix and Evercom) as an Unrestricted Subsidiary in accordance with the
      terms of this Indenture,

            (4) at such time as such Subsidiary Guarantor (other than T-Netix
      and Evercom) does not have any Indebtedness outstanding that would have
      required such Subsidiary Guarantor to enter into a Guarantee Agreement
      pursuant to Section 4.13 and the Company provides an Officers' Certificate
      to the Trustee certifying that no such Indebtedness is outstanding and
      that the Company elects to have such Subsidiary Guarantor released from
      this Article 10, or

            (5) upon defeasance of the Securities pursuant to Article 8, or

            (6) upon the full satisfaction of the Company's obligations under
      this Indenture; or

            (7) if such Subsidiary Guarantor ceases to be a Subsidiary as a
      result of any foreclosure of any pledge or security interest in favor of
      First-Priority Lien Obligations, subject to, in each case, the application
      of the proceeds of such foreclosure pursuant to Section 11.03.

      provided, however, that in the case of clauses (1) and (2) above, (i) such
      sale or other disposition is made to a Person other than the Company or a
      Subsidiary of the Company, (ii) such sale or disposition is otherwise
      permitted by this Indenture and (iii) the Company provides an Officers'
      Certificate to the Trustee to the effect that the Company shall comply
      with its obligations under Section 4.06.

At the request of the Company, the Trustee shall execute and deliver an
appropriate instrument evidencing such release.

            SECTION 10.07. Contribution. Each Subsidiary Guarantor that makes a
payment under its Subsidiary Guarantee shall be entitled upon payment in full of
all Guaranteed Obligations under this Indenture to a contribution from each
other Subsidiary Guarantor in an amount equal to such other Subsidiary
Guarantor's pro rata portion

<PAGE>

                                                                              75

of such payment based on the respective net assets of all the Subsidiary
Guarantors at the time of such payment determined in accordance with GAAP.

                                   ARTICLE 11

                               Security Documents

            SECTION 11.01. Collateral and Security Documents. On and after the
Issue Date, the due and punctual payment of the principal of and interest
(including additional interest, if any) on the Securities when and as the same
shall be due and payable, whether on an interest payment date, at maturity, by
acceleration, repurchase, redemption or otherwise, and interest on the overdue
principal of and interest (including additional interest, if any) on the
Securities and performance of all other Guaranteed Obligations of the Company
and the Subsidiary Guarantors to the Holders, the Trustee or the Collateral
Agent under this Indenture, the Securities and the Security Documents, according
to the terms hereunder or thereunder, shall be secured as provided in the
Security Documents, which define the terms of the Liens that secure the
Guaranteed Obligations, subject to the terms of the Intercreditor Agreement. The
Trustee and the Company hereby acknowledge and agree that the Trustee or the
Collateral Agent, as the case may be, holds the Collateral in trust for the
benefit of the Trustee and the Holders, in each case pursuant to the terms of
the Security Documents and the Intercreditor Agreement. Each Holder, by
accepting a Security, consents and agrees to the terms of the Security Documents
(including the provisions providing for foreclosure and release of Collateral
and amendment of such documents) as the same may be in effect or may be amended
from time to time in accordance with their terms and this Indenture, and
authorizes and directs the Collateral Agent to enter into the Security Documents
and to perform its obligations and exercise its rights thereunder in accordance
therewith; provided, however, that if any of the provisions of the Security
Documents limit, qualify or conflict with the duties imposed by the provisions
of the TIA, the TIA shall control. The Company shall deliver to the Trustee (if
it is not itself then the Collateral Agent) copies of all documents delivered to
the Collateral Agent pursuant to the Security Documents, and shall do or cause
to be done all such acts and things as may be reasonably required by the next
sentence of this Section 11.01, to assure and confirm to the Trustee and the
Collateral Agent the security interest in the Collateral contemplated hereby, by
the Security Documents or any part thereof, as from time to time constituted, so
as to render the same available for the security and benefit of this Indenture
and of the Securities secured hereby, according to the intent and purposes
herein expressed. The Company shall take, and shall cause its Subsidiaries to
take, any and all actions reasonably required to cause the Security Documents to
create and maintain, as security for its Obligations and the Obligations of the
Subsidiary Guarantors hereunder, a valid and enforceable perfected Lien and
security interest in and on all of the Collateral (subject to the terms of the
Intercreditor Agreement), in favor of the Collateral Agent for the benefit of
the Trustee and the Holders, second in priority to any and all security
interests at any time granted in the Collateral to secure the First-Priority
Lien Obligations. Notwithstanding the foregoing, the Security Documents may be
amended from time to time to add other parties holding other Second-Priority
Lien Obligations and other First-Priority Lien Obligations permitted to be
incurred under Sections 4.03 and 4.11.

            SECTION 11.02. Recordings and Opinions. (a) The Company and the
Subsidiary Guarantors shall furnish to the Collateral Agent and the Trustee (if
the Trustee is not then the Collateral Agent), on or before the time when the
Company is required to provide annual reports pursuant to Section 4.02 with
respect to the preceding fiscal year, an opinion of counsel:

            (1) stating substantially to the effect that, in the opinion of such
      counsel, such action has been taken with respect to the recordings,
      registerings, filings, re-recordings, re-registerings and re-filings of
      this Indenture, the Security Documents and all financing statements,
      continuation statements or other instruments of further assurance as is
      necessary to maintain the Lien of this Indenture or any Security Documents
      in the Collateral and reciting with respect to the security interests in
      such Collateral the details of such action or referencing to prior
      Opinions of Counsel in which such details are given; or

            (2) to the effect that, in the opinion of such counsel, no such
      action is necessary to maintain such Lien under this Indenture and the
      Security Documents.

            (b) The Company shall comply with the provisions of TIA Section
314(b) and (d).

            SECTION 11.03. Release of Collateral. (a) Subject to subsections (b)
and (c) of this Section 11.03, Collateral may be released from the Lien and
security interest created by the Security Documents at any time or from time to
time in accordance with the provisions of the Security Documents or as provided
hereby. Upon the request of the Company pursuant to an Officers' Certificate
certifying that all conditions precedent hereunder have been met, the Company
and the Subsidiary Guarantors shall be entitled to a release of assets included
in the Collateral from the Liens securing the Securities, and the Collateral
Agent and the Trustee (if the Trustee is not then the Collateral Agent) shall
release the same from such Liens at the Company's sole cost and expense, under
one or more of the following circumstances:

            (1) to enable the Company or any Restricted Subsidiary to sell,
      exchange or otherwise dispose of any of the Collateral as permitted under
      Section 4.06;

            (2) in the case of a Subsidiary Guarantor that is released from its
      Subsidiary Guarantee with respect to the Securities, the release of the
      property and assets of such Subsidiary Guarantor; or

            (3) pursuant to an amendment or waiver in accordance with Article 9
      of this Indenture.

            Upon receipt of such Officers' Certificate and any necessary or
proper instruments of termination, satisfaction or release prepared by the
Company, the Collateral Agent shall execute, deliver or acknowledge such
instruments or releases provided to it to evidence the release of any Collateral
permitted to be released pursuant to this Indenture or the Security Documents.

<PAGE>

                                                                              77

            (b) Except as otherwise provided in the Security Documents, no
Collateral may be released from the Lien and security interest created by the
Security Documents unless the Officers' Certificate required by this Section
11.03, dated not more than five days prior to the date of the application for
such release, has been delivered to the Collateral Agent and the Trustee (if the
Trustee is not then the Collateral Agent).

            (c) At any time when a Default or Event of Default has occurred and
is continuing and the maturity of the Securities has been accelerated (whether
by declaration or otherwise) and the Trustee (if not then the Collateral Agent)
has delivered a notice of acceleration to the Collateral Agent, no release of
Collateral pursuant to the provisions of this Indenture or the Security
Documents shall be effective as against the Holders, except as otherwise
provided in the Intercreditor Agreement.

            SECTION 11.04. Permitted Releases Not To Impair Lien; Trust
Indenture Act Requirements. The release of any Collateral from the terms hereof
and of the Security Documents or the release of, in whole or in part, the Liens
created by the Security Documents, shall not be deemed to impair the security
under this Indenture in contravention of the provisions hereof if and to the
extent the Collateral or Liens are released pursuant to the applicable Security
Documents and the terms of this Article 11. The Trustee and each of the Holders
acknowledge that a release of Collateral or a Lien strictly in accordance with
the terms of the Security Documents and of this Article 11 shall not be deemed
for any purpose to be in contravention of the terms of this Indenture. To the
extent applicable, the Company and each obligor on the Securities shall cause
TIA Section 313(b), relating to reports, and TIA Section 314(d), relating to
the release of property or securities from the Lien hereof and of the Security
Documents, to be complied with. Any certificate or opinion required by Section
314(d) of the TIA may be made by an officer of the Company, except in cases
which Section 314(d) of the TIA requires that such certificate or opinion be
made by an independent person, which person shall be an independent engineer,
appraiser or other expert selected or approved by the Trustee and the Collateral
Agent in the exercise of reasonable care.

            SECTION 11.05. Certificates of the Trustee. In the event that the
Company wishes to release Collateral in accordance with this Indenture and the
Security Documents at a time when the Trustee is not itself also the Collateral
Agent and the Company has delivered the certificates and documents required by
the Security Documents and Section 11.03 hereof, the Trustee shall determine
whether it has received all documentation required by TIA Section 314(d) in
connection with such release and, based on such determination, shall deliver a
certificate to the Collateral Agent setting forth such determination.

            SECTION 11.06. Suits To Protect the Collateral. Subject to the
provisions of Article 7 hereof and the Intercreditor Agreement, the Trustee in
its sole discretion and without the consent of the Holders, on behalf of the
Holders, may or may direct the Collateral Agent to take all actions necessary or
appropriate or that it may deem necessary or appropriate in order to:

            (a) enforce any of the terms of the Security Documents; and

<PAGE>

                                                                              78

            (b) collect and receive any and all amounts payable in respect of
      the Guaranteed Obligations of the Company hereunder.

            Subject to the provisions of the Security Documents and the
Intercreditor Agreement, the Trustee shall have power to institute and to
maintain such suits and proceedings as it may deem expedient to prevent any
impairment of the Collateral by any acts which may be unlawful or in violation
of any of the Security Documents or this Indenture, and such suits and
proceedings as the Trustee, in its sole discretion, may deem expedient to
preserve or protect its interests and the interests of the Holders in the
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or otherwise
invalid if the enforcement of, or compliance with, such enactment, rule or order
would impair the Lien on the Collateral or be prejudicial to the interests of
the Holders or the Trustee).

            SECTION 11.07. Authorization of Receipt of Funds by the Trustee
Under the Security Documents. Subject to the provisions of the Intercreditor
Agreement, the Trustee is authorized to receive any funds for the benefit of the
Holders distributed under the Security Documents, and to make further
distributions of such funds to the Holders according to the provisions of this
Indenture.

            SECTION 11.08. Purchaser Protected. In no event shall any purchaser
in good faith of any property purported to be released hereunder be bound to
ascertain the authority of the Collateral Agent or the Trustee to execute the
release or to inquire as to the satisfaction of any conditions required by the
provisions hereof for the exercise of such authority or to see to the
application of any consideration given by such purchaser or other transferee;
nor shall any purchaser or other transferee of any property or rights permitted
by this Article 11 to be sold be under any obligation to ascertain or inquire
into the authority of the Company or the applicable Subsidiary Guarantor to make
any such sale or other transfer.

            SECTION 11.09. Powers Exercisable by Receiver or Trustee. In case
the Collateral shall be in the possession of a receiver or trustee, lawfully
appointed, the powers conferred in this Article 11 upon the Company or a
Subsidiary Guarantor with respect to the release, sale or other disposition of
such property may be exercised by such receiver or trustee, and an instrument
signed by such receiver or trustee shall be deemed the equivalent of any similar
instrument of the Company or a Subsidiary Guarantor or of any officer or
officers thereof required by the provisions of this Article 11; and if the
Trustee shall be in the possession of the Collateral under any provision of this
Indenture, then, subject to the provisions of the Intercreditor Agreement, such
powers may be exercised by the Trustee.

            SECTION 11.10. Release Upon Termination of the Company's
Obligations. In the event that the Company delivers to the Trustee, in form and
substance acceptable to it, an Officers' Certificate certifying that all the
obligations under this Indenture, the Securities and the Security Documents have
been satisfied and discharged by complying with the provisions of Article 8 and
Section 7.07 or by the payment in full

<PAGE>

                                                                              79

of the Company's obligations under the Securities, this Indenture and the
Security Documents, and all such obligations have been so satisfied, the Trustee
shall deliver to the Company and the Collateral Agent a notice stating that the
Trustee, on behalf of the Holders, disclaims and gives up any and all rights it
has in or to the Collateral (other than with respect to funds held by the
Trustee pursuant to Article 8), and any rights it has under the Security
Documents, and upon receipt by the Collateral Agent of such notice, the
Collateral Agent shall be deemed not to hold a Lien in the Collateral on behalf
of the Trustee and shall do or cause to be done all acts reasonably necessary to
release such Lien as soon as is reasonably practicable.

            SECTION 11.11. Collateral Agent. (a) The Trustee shall initially act
as Collateral Agent and shall be authorized to appoint co-Collateral Agents as
necessary in its sole discretion. Except as otherwise explicitly provided herein
or in the Security Documents, neither the Collateral Agent nor any of its
respective officers, directors, employees or agents shall be liable for failure
to demand, collect or realize upon any of the Collateral or for any delay in
doing so or shall be under any obligation to sell or otherwise dispose of any
Collateral upon the request of any other Person or to take any other action
whatsoever with regard to the Collateral or any part thereof. The Collateral
Agent shall be accountable only for amounts that it actually receives as a
result of the exercise of such powers, and neither the Collateral Agent nor any
of its officers, directors, employees or agents shall be responsible for any act
or failure to act hereunder, except for its own willful misconduct, gross
negligence or bad faith.

            (a) The Trustee, as Collateral Agent, is authorized and directed to
(i) enter into the Security Documents, (ii) enter into the Intercreditor
Agreement, (iii) bind the Holders on the terms as set forth in the Security
Documents and (iv) perform and observe its obligations under the Security
Documents.

            (b) If the Company (i) Incurs First-Priority Lien Obligations at any
time when no intercreditor agreement is in effect or at any time when
Indebtedness constituting First-Priority Lien Obligations entitled to the
benefit of an existing Intercreditor Agreement is concurrently retired, and (ii)
delivers to the Collateral Agent an Officers' Certificate so stating and
requesting the Collateral Agent to enter into an intercreditor agreement (on
substantially the same terms as the Intercreditor Agreement in effect on the
Issue Date) in favor of a designated agent or representative for the holders of
the First-Priority Lien Obligations so Incurred, the Collateral Agent shall (and
is hereby authorized and directed to) enter into such intercreditor agreement,
bind the Holders on the terms set forth therein and perform and observe its
obligations thereunder.

            SECTION 11.12. Designations. Except as provided in the next
sentence, for purposes of the provisions hereof and the Intercreditor Agreement
requiring the Company to designate Indebtedness for the purposes of the terms
"First-Priority Lien Obligations" and "other Second-Priority Lien Obligations"
or any other such designations hereunder or under the Intercreditor Agreement,
any such designation shall be sufficient if the relevant designation is set
forth in writing, signed on behalf of the Company by an Officer and delivered to
the Trustee and the Collateral Agent. For all purposes hereof and the
Intercreditor Agreement, the Company hereby designates the "Obligations" as

<PAGE>

                                                                              80

defined in the Credit Agreement as in effect on the Issue Date and as amended
from time to time to the extent not prohibited by this Indenture as
"First-Priority Lien Obligations."

            SECTION 11.13. Limitation on Duty of Trustee in Respect of
Collateral.

            (a) Beyond the exercise of reasonable care in the custody thereof,
the Trustee shall have no duty as to any Collateral in its possession or control
or in the possession or control of any agent or bailee or any income thereon or
as to preservation of rights against prior parties or any other rights
pertaining thereto and the Trustee shall not be responsible for filing any
financing or continuation statements or recording any documents or instruments
in any public office at any time or times or otherwise perfecting or maintaining
the perfection of any security interest in the Collateral. The Trustee shall be
deemed to have exercised reasonable care in the custody of the Collateral in its
possession if the Collateral is accorded treatment substantially equal to that
which it accords its own property and shall not be liable or responsible for any
loss or diminution in the value of any of the Collateral, by reason of the act
or omission of any carrier, forwarding agency or other agent or bailee selected
by the Trustee in good faith.

            (b) The Trustee shall not be responsible for the existence,
genuineness or value of any of the Collateral or for the validity, perfection,
priority or enforceability of the Liens in any of the Collateral, whether
impaired by operation of law or by reason of any action or omission to act on
its part hereunder, except to the extent such action or omission constitutes
gross negligence, bad faith or willful misconduct on the part of the Trustee,
for the validity or sufficiency of the Collateral or any agreement or assignment
contained therein, for the validity of the title of the Company to the
Collateral, for insuring the Collateral or for the payment of taxes, charges,
assessments or Liens upon the Collateral or otherwise as to the maintenance of
the Collateral. The Trustee shall have no duty to ascertain or inquire as to the
performance or observance of any of the terms of this Indenture or the Security
Documents by the Company, the Issuer, ING Capital LLC, the Senior Lenders or the
Collateral Agent.

shall control. SECTION 12.02. Notices. Any notice or communication shall be in

      and are accompanied by the following additional information and documents,
      as applicable:

                  (A)   if such Definitive Securities are being delivered to the
            Registrar by a Holder for registration in the name of such Holder,
            without transfer, a certification from such Holder to that effect;

                                                                               7

            (i)   certification, in the form set forth on the reverse of the
      Security, that such Definitive Security is either (A) being transferred to
      a QIB in accordance with Rule 144A, (B) being transferred to an IAI or (C)
      being transferred after expiration of the Distribution Compliance Period
      by a Person who initially purchased such Security in reliance on
      Regulation S to a buyer who elects to hold its interest in such Security
      in the form of a beneficial interest in the Permanent Regulation S Global
      Security; and

            (ii)  written instructions directing the Trustee to make, or to
      direct the Securities Custodian to make, an adjustment on its books and
      records with respect to such Rule 144A Global Security (in the case of a
      transfer pursuant to clause (b)(i)(A)), IAI Global Security (in the case
      of a transfer pursuant to clause (b)(1)(B)) or Permanent Regulation S
      Global Security (in the case of a transfer pursuant to clause (b)(i)(B))
      to reflect an increase in the aggregate principal amount of the Securities
      represented by the Rule 144A Global Security, IAI Global Security or
      Permanent Regulation S Global Security, as applicable, such instructions
      to contain information regarding the Depository account to be credited
      with such increase,

then the Trustee shall cancel such Definitive Security and cause, or direct the
Securities Custodian to cause, in accordance with the standing instructions and
procedures existing between the Depository and the Securities Custodian, the
aggregate principal amount of Securities represented by the Rule 144A Global
Security, IAI Global Security or Permanent Regulation S Global Security, as
applicable, to be increased by the aggregate principal amount of the Definitive
Security to be exchanged and shall credit or cause to be credited to the account
of the Person specified in such instructions a beneficial interest in the Rule
144A Global Security, IAI Global Security or Permanent Regulation S Global
Security, as applicable, equal to the principal amount of the Definitive
Security so canceled. If no Rule 144A Global Securities, IAI Global Securities
or Permanent Regulation S Global Securities, as applicable, are then
outstanding, the Company shall issue and the Trustee shall authenticate, upon
written order of the Company in the form of an Officers' Certificate of the
Company, a new Rule 144A Global Security, IAI Global Security or Permanent
Regulation S Global Security, as applicable, in the appropriate principal
amount.

            (c)   Transfer and Exchange of Global Securities.

                  (i)   The transfer and exchange of Global Securities or
            beneficial interests therein shall be effected through the
            Depository, in accordance with this Indenture (including applicable
            restrictions on transfer set forth herein, if any) and the
            procedures of the Depository therefor. A transferor of a beneficial
            interest in a Global Security shall deliver to the Registrar a
            written order given in accordance with the Depository's procedures
            containing information regarding the participant account of the
            Depository to be credited with a beneficial interest in the Global
            Security. The Registrar shall, in accordance with such instructions
            instruct the Depository to credit to the account of the Person
            specified in

<PAGE>

                                                                               8

            such instructions a beneficial interest in the Global Security and
            to debit the account of the Person making the transfer the
            beneficial interest in the Global Security being transferred.

                  (ii)  If the proposed transfer is a transfer of a beneficial
            interest in one Global Security to a beneficial interest in another
            Global Security, the Registrar shall reflect on its books and
            records the date and an increase in the principal amount of the
            Global Security to which such interest is being transferred in an
            amount equal to the principal amount of the interest to be so
            transferred, and the Registrar shall reflect on its books and
            records the date and a corresponding decrease in the principal
            amount of the Global Security from which such interest is being
            transferred.

                  (iii) Notwithstanding any other provisions of this Appendix
            (other than the provisions set forth in Section 2.4), a Global
            Security may not be transferred as a whole except 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.

                  (iv)  In the event that Global Security is exchanged for
            Definitive Securities to Section 2.4 of this Appendix, prior to the
            consummation of a Registered Exchange Offer or the effectiveness of
            a Shelf Registration Statement with respect to such Securities, such
            Securities may be exchanged only in accordance with such procedures
            as are substantially consistent with the provisions of this Section
            2.3 (including the certification requirements set forth on the
            reverse of the Initial Securities intended to ensure that such
            transfers comply with Rule 144A, Regulation S or another applicable
            exemption under the Securities Act, as the case may be) and such
            other procedures as may from time to time be adopted by the Company.

            (d)   Restrictions on Transfer of Temporary Regulation S Global
Securities. During the Distribution Compliance Period, beneficial ownership
interests in Temporary Regulation S Global Securities may only be sold, pledged
or transferred in accordance with the Applicable Procedures and only (i) to the
Company, (ii) in an offshore transaction in accordance with Regulation S (other
than a transaction resulting in an exchange for an interest in a Permanent
Regulation S Global Security), (iii) pursuant to an effective registration
statement under the Securities Act, in each case in accordance with any
applicable securities laws of any State of the United States.

            (e)   Legend.

            (iii) and (iv), each Security certificate evidencing the Global
            Securities (and all Securities issued in exchange therefor or in
            substitution thereof), in the

                  USED ABOVE HAVE THE MEANINGS GIVEN TO THEM IN REGULATION S
                  UNDER THE SECURITIES ACT.

            Each Definitive Security shall also bear the following additional

                  RESTRICTIONS.

                  (ii)  Upon any sale or transfer of a Transfer Restricted
            Security (including any Transfer Restricted Security represented by

            Exchange Securities pursuant to and during the period of the
            effectiveness of a Shelf Registration Statement with respect to such
            Initial Securities or Private Exchange Securities, as the case may
            be, all requirements pertaining to legends on such Initial Security
            or such Private Exchange Security shall cease to apply, the

                  Security or such Private Exchange Security issued to certain
                  Holders be issued in global form shall cease to apply, and a
                  certificated Initial Security or Private Exchange Security or
                  an Initial Security or Private Exchange Security in global
                  form, in each case without restrictive transfer legends, shall
                  be available to the transferee of the Holder of such Initial
                  Securities or Private Exchange Securities upon exchange of
                  such transferring Holder's certificated Initial Security or
                  Private Exchange Security or directions to transfer such
                  Holder's interest in the Global Security, as applicable.

                  (iv)  Upon the consummation of a Registered Exchange Offer
      with respect to the Initial Securities, all requirements pertaining to
      such Initial Securities that Initial Securities issued to certain Holders
      be issued in global form shall still apply with respect to Holders of such
      Initial Securities that do not exchange their Initial Securities, and
      Exchange Securities in certificated or global form, in each case without
      the restricted securities legend set forth in Exhibit 1 hereto shall be
      available to Holders that exchange such Initial Securities in such

            (f)   Cancellation or Adjustment of Global Security. At such time as
all beneficial interests in a Global Security have either been exchanged for
Definitive Securities, redeemed, purchased or canceled, such Global Security
shall be returned to the Depository for cancellation or retained and canceled by
the Trustee. At any time prior to such cancellation, if any beneficial interest
in a Global Security is exchanged for certificated Securities, redeemed,
purchased or canceled, the principal amount of Securities represented by such
Global Security shall be reduced and an adjustment shall be made on the books
and records of the Trustee (if it is then the Securities Custodian for such
Global Security) with respect to such Global Security, by the Trustee or the
Securities Custodian, to reflect such reduction.

            (g)   No Obligation of the Trustee.

                  (i)   The Trustee shall have no responsibility or obligation
            to any beneficial owner of a Global Security, a member of, or a
            participant in the Depository or other Person with respect to the
            accuracy of the records of the Depository or its nominee or of any
            participant or member thereof, with respect to any ownership
            interest in the Securities or with respect to the delivery to any
            participant, member, beneficial owner or other Person (other than
            the Depository) of any notice (including any notice of

                  redemption) or the payment of any amount, under or with
                  respect to such Securities. All notices and communications to
                  be given to the Holders and all payments to be made to Holders
                  under the Securities shall be given or made only to or upon
                  the order of the registered Holders (which shall be the
                  Depository or its nominee in the case of a Global Security).
                  The rights of beneficial owners in any Global Security shall
                  be exercised only through the Depository subject to the
                  applicable rules and procedures of the Depository. The Trustee
                  may rely and shall be fully protected in relying upon
                  information furnished by the Depository with respect to its
                  members, participants and any beneficial owners.

                  (ii)  The Trustee shall have no obligation or duty to monitor,
            determine or inquire as to compliance with any restrictions on
            transfer imposed under this Indenture or under applicable law with
            respect to any transfer of any interest in any Security (including
            any transfers between or among Depository participants, members or
            beneficial owners in any Global Security) other than to require
            delivery of such certificates and other documentation or evidence as
            are expressly required by, and to do so if and when expressly
            required by, the terms of this Indenture, and to examine the same to
            determine substantial compliance as to form with the express
            requirements hereof.

            2.4   Definitive Securities.

            (a)   A Global Security deposited with the Depository or with the
Trustee as Securities Custodian for the Depository pursuant to Section 2.1 shall

transfer complies with Section 2.3 hereof and (i) the Depository notifies the
Company that it is unwilling or unable to continue as Depository for such Global
Security and the Depository fails to appoint a successor depository or if at any
time such Depository ceases to be a "clearing agency" registered under the
Exchange Act, in either case, and a successor depository is not appointed by the

                11% Second-Priority Senior Secured Note Due 2011

1.    Interest

      Securus Technologies, Inc., a Delaware corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), promises to pay interest on the principal amount
of this Security at the rate per annum shown above; provided, however, that if a
Registration Default (as defined in the Registration Rights Agreement) occurs,
additional interest shall accrue on this Security at a rate of 0.50% per annum
(increasing by an additional 0.50% per annum after each consecutive 90-day
period that occurs after the date on which such Registration default occurs up
to a maximum additional interest rate of 2.00%) from and including the date on
which any such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured. The Company shall pay interest
semiannually on March 1 and September 1 of each year, commencing March 1, 2005.
Interest on the Securities shall accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from September 9, 2004.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
this Security plus 1.0% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.    Method of Payment

      The Company shall pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the February 15 or August 15 next preceding the interest payment
date even if Securities are canceled after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company shall pay principal and interest in
money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities
represented by a Global Security (including principal, premium and interest)
shall be made by wire transfer of immediately available funds to the accounts
specified by the Depository. The Company shall make all payments in respect of a
certificated Security (including principal, premium and interest) by mailing a
check to the registered address of each Holder thereof; provided, however, that
payments on a certificated Security shall be made by wire transfer to a U.S.
dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice to the Trustee
or the Paying Agent to such effect designating such account no later than 30
days immediately preceding the relevant due date for payment (or such other date
as the Trustee may accept in its discretion).

shall be entitled, subject to its compliance with Section 4.03 of the Indenture,
to issue Additional Securities pursuant to Section 2.13 of the Indenture. The

</TABLE>

      In addition, prior to September 1, 2007, the Company shall be entitled at
its option on one or more occasions to redeem Securities (which includes
Additional Securities, if any) in an aggregate principal amount not to exceed
35% of the aggregate principal amount of the Securities (which includes
Additional Securities, if any) originally issued at a redemption price
(expressed as a percentage of principal amount) of 111.000%, plus accrued and
unpaid interest to the redemption date, with the net cash proceeds from one or
more Equity Offerings; provided, however, that (1) at least 65% of such
aggregate principal amount of Securities (which includes Additional Securities,
if any) remains outstanding immediately after the occurrence of each such
redemption (other than Securities held, directly or indirectly, by the Company
or its Affiliates); and (2) each such redemption occurs within 90 days after the
date of the related Equity Offering.

      Prior to September 1, 2008, the Company shall be entitled at its option to
redeem all, but not less than all, of the Securities at a redemption price equal
to 100% of the principal amount of the Securities plus the Applicable Premium as
of, and accrued and unpaid interest to, the redemption date (subject to the
right of Holders on the relevant record date to receive interest due on the
relevant interest payment date). The Company shall cause notice of such
redemption to be mailed by first-class mail to each Holder's registered address,
not less than 30 nor more than 60 days prior to the redemption date.

6.    Notice of Redemption

      Notice of redemption shall be mailed at least 30 days but not more than 60
days before the redemption date to each Holder of Securities to be redeemed at
his registered address. Securities in denominations larger than $1,000 principal
amount may be redeemed in part but only in whole multiples of $1,000. If money

the Paying Agent on or before the redemption date and certain other conditions
are satisfied, on and after such date interest ceases to accrue on such
Securities (or such portions thereof) called for redemption.

7.    Put Provisions

be repurchased plus accrued interest to the date of repurchase (subject to the
right of holders of record on the relevant record date to receive interest due
on the related interest payment date) as provided in, and subject to the terms
of, the Indenture.

                                                                              11

      The Securities shall be secured by the Collateral on the terms and subject
to the conditions set forth in the Indenture and the Security Documents, such
security interest to be second in priority to security interests granted for the
benefit of holders of First-Priority Lien Obligations. The Trustee and the
Collateral Agent, as the case may be, hold the Collateral in trust for the
benefit of the Trustee and the Holders, in each case pursuant to the Security
Documents and the Intercreditor Agreement. Each Holder, by accepting this
Security, consents and agrees to the terms of the Security Documents (including
the provisions providing for the foreclosure and release of Collateral) and the
Intercreditor Agreement as the same may be in effect or may be amended from time
to time in accordance with their terms and the Indenture and authorizes and

$1,000 principal amount and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements or transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

11.   Persons Deemed Owners

      The registered Holder of this Security may be treated as the owner of it
for all purposes.

12.   Unclaimed Money

      If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Company
at its request unless an abandoned property law designates another Person. After
any such payment, Holders entitled to the money must look only to the Company
and not to the Trustee for payment.

                                                                              12

13.   Discharge and Defeasance

      Subject to certain conditions, the Company at any time shall be entitled
to terminate some or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.

14.   Amendment, Waiver

      Subject to certain exceptions set forth in the Indenture, (a) the
Indenture and the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (b) any default or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in principal amount outstanding of
the Securities. Subject to certain exceptions set forth in the Indenture,
without the consent of any Securityholder, the Company, the Subsidiary
Guarantors and the Trustee shall be entitled to amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities, including Subsidiary Guaranties, or
to provide further security for the Securities, or to add additional covenants
or surrender rights and powers conferred on the Company or the Subsidiary
Guarantors, or to comply with any requirement of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder, or to make amendments to
provisions of the Indenture relating to the form, authentication, transfer and
legending of the Securities, or in the event that such amendment is expressly
permitted pursuant to Section 11.01(b) of the Indenture or pursuant to the
Security Documents.

15.   Defaults and Remedies

      Under the Indenture, Events of Default include (a) default for 30 days in
payment of interest on the Securities; (b) default in payment of principal on
the Securities at maturity, upon redemption pursuant to paragraph 5 of the
Securities, upon acceleration or otherwise, or failure by the Company to
purchase Securities when required; (c) failure by the Company or any Subsidiary
Guarantor to comply with other agreements in the Indenture or the Securities, in
certain cases subject to notice and lapse of time; (d) certain accelerations
(including failure to pay within any grace period after final maturity) of other
Indebtedness of the Company, a Subsidiary Guarantor or any Significant
Subsidiary if the amount accelerated (or so unpaid) exceeds $10.0 million; (e)
certain events of bankruptcy or insolvency with respect to the Company, the
Subsidiary Guarantors and the Significant Subsidiaries; (f) certain judgments or
decrees for the payment of money in excess of $10.0 million; (g) certain
defaults with respect to Subsidiary Guaranties; and (h) certain defaults with
respect to the Security Documents. If an Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the Securities may declare all the Securities to be due and payable immediately.
Certain events of bankruptcy or insolvency are Events of Default which shall
result in the

<PAGE>

                                                                              13

Securities being due and payable immediately upon the occurrence of such Events
of Default.

      Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives indemnity or security satisfactory to it.
Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing Default
(except a Default in payment of principal or interest) if it determines that
withholding notice is in the interest of the Holders.

16.   Trustee Dealings with the Company

      Subject to certain limitations imposed by the Act, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

17.   No Recourse Against Others

      A director, officer, employee or stockholder, as such, of the Company or
the Trustee shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. By accepting a Security,
each Securityholder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

18.   Authentication

      This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

19.   Abbreviations

      Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.   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 Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the

                                                                              14

accuracy of such numbers either as printed on the Securities or as contained in
any notice of redemption and reliance may be placed only on the other
identification numbers placed thereon.

[21.  Holders' Compliance with Registration Rights Agreement.

      Each Holder of a Security, by acceptance hereof, acknowledges and agrees
to the provisions of the Registration Rights Agreement, including the
obligations of the Holders with respect to a registration and the
indemnification of the Company to the extent provided therein.]

LAWS OF THE STATE OF NEW YORK.

                11% Second-Priority Senior Secured Note Due 2011

1.    Interest

      Securus Technologies, Inc., a Delaware corporation (such corporation, and
its successors and assigns under the Indenture hereinafter referred to, being
herein called the "Company"), promises to pay interest on the principal amount
of this Security at the rate per annum shown above; provided, however, that if a
Registration Default (as defined in the Registration Rights Agreement) occurs,
additional interest shall accrue on this Security at a rate of 0.50% per annum
(increasing by an additional 0.50% per annum after each consecutive 90-day
period that occurs after the date on which such Registration default occurs up
to a maximum additional interest rate of 2.00%) from and including the date on
which any such Registration Default shall occur to but excluding the date on
which all Registration Defaults have been cured. The Company shall pay interest
semiannually on March 1 and September 1 of each year, commencing March 1, 2005.
Interest on the Securities shall accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from September 9, 2004.
Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Company shall pay interest on overdue principal at the rate borne by
this Security plus 1.0% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.    Method of Payment

      The Company shall pay interest on the Securities (except defaulted
interest) to the Persons who are registered holders of Securities at the close
of business on the February 15 or August 15 next preceding the interest payment
date even if Securities are canceled after the record date and on or before the
interest payment date. Holders must surrender Securities to a Paying Agent to
collect principal payments. The Company shall pay principal and interest in
money of the United States that at the time of payment is legal tender for
payment of public and private debts. Payments in respect of the Securities
represented by a Global Security (including principal, premium and interest)
shall be made by wire transfer of immediately available funds to the accounts
specified by The Depository Trust Company. The Company shall make all payments
in respect of a certificated Security (including principal, premium and
interest) by mailing a check to the registered address of each Holder thereof;
provided, however, that payments on a certificated Security shall be made by
wire transfer to a U.S. dollar account maintained by the payee with a bank in
the United States if such Holder elects payment by wire transfer by giving
written notice to the Trustee or the Paying Agent to such effect designating
such account no later than 30 days immediately preceding the relevant due date
for payment (or such other date as the Trustee may accept in its discretion).

<PAGE>

                                                                               6

3.    Paying Agent and Registrar

      Initially, The Bank of New York Trust Company, N.A., a New York banking
corporation (the "Trustee"), shall act as Paying Agent and Registrar. The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice. The Company or any of its domestically incorporated Wholly Owned
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.    Indenture

      The Company issued the Securities under an Indenture dated as of September
9, 2004 ("Indenture"), among the Company, the Subsidiary Guarantors and the
Trustee. The terms of the Securities include those stated in the Indenture and
those made part of the Indenture by reference to the Trust Indenture Act of 1939
(15 U.S.C. Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the
"Act"). Terms defined in the Indenture and not defined herein have the meanings
ascribed thereto in the Indenture. The Securities are subject to all such terms,
and Securityholders are referred to the Indenture and the Act for a statement of
those terms.

      The Securities are general secured obligations of the Company. The Company
shall be entitled, subject to its compliance with Section 4.03 of the Indenture,
to issue Additional Securities pursuant to Section 2.13 of the Indenture. The
Initial Securities issued on the Issue Date, any Additional Securities and all
Exchange Securities or Private Exchange Securities issued in exchange therefor
shall be treated as a single class for all purposes under the Indenture. The
Indenture contains covenants that limit the ability of the Company and its
subsidiaries to incur additional indebtedness; pay dividends or distributions
on, or redeem or repurchase capital stock; make investments; issue or sell
capital stock of subsidiaries; engage in transactions with affiliates; create
liens on assets; transfer or sell assets; guarantee indebtedness; restrict
dividends or other payments of subsidiaries; consolidate, merge or transfer all
or substantially all of its assets and the assets of its subsidiaries; and
engage in sale/leaseback transactions. These covenants are subject to important
exceptions and qualifications.

5.    Optional Redemption

      Except as set forth below, the Company shall not be entitled to redeem the
Securities.

      On and after September 1, 2008, the Company shall be entitled at its
option to redeem all or a portion of the Securities upon not less than 30 nor
more than 60 days' notice, at the redemption prices (expressed in percentages of
principal amount, on the redemption date) plus accrued interest to the
redemption date (subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date),

      In addition, prior to August 1, 2007, the Company shall be entitled at its
option on one or more occasions to redeem Securities (which includes Additional
Securities, if any) in an aggregate principal amount not to exceed 35% of the
aggregate principal amount of the Securities (which includes Additional
Securities, if any) originally issued at a redemption price (expressed as a
percentage of principal amount) of 111.000%, plus accrued and unpaid interest to
the redemption date, with the net cash proceeds from one or more Equity
Offerings; provided, however, that (1) at least 65% of such aggregate principal
amount of Securities (which includes Additional Securities, if any) remains
outstanding immediately after the occurrence of each such redemption (other than
Securities held, directly or indirectly, by the Company or its Affiliates); and
(2) each such redemption occurs within 90 days after the date of the related
Equity Offering.

      Prior to September 1, 2008, the Company shall be entitled at its option to
redeem all, but not less than all, of the Securities at a redemption price equal
to 100% of the principal amount of the Securities plus the Applicable Premium as
of, and accrued and unpaid interest to, the redemption date (subject to the
right of Holders on the relevant record date to receive interest due on the
relevant interest payment date). The Company shall cause notice of such
redemption to be mailed by first-class mail to each Holder's registered address,
not less than 30 nor more than 60 days prior to the redemption date.

6.    Notice of Redemption

      Notice of redemption shall be mailed at least 30 days but not more than 60
days before the redemption date to each Holder of Securities to be redeemed at
his registered address. Securities in denominations larger than $1,000 principal
amount may be redeemed in part but only in whole multiples of $1,000. If money
sufficient to pay the redemption price of and accrued interest on all Securities
(or portions thereof) to be redeemed on the redemption date is deposited with
the Paying Agent on or before the redemption date and certain other conditions
are satisfied, on and after such date interest ceases to accrue on such
Securities (or such portions thereof) called for redemption.

7.    Put Provisions

      Upon a Change of Control, any Holder of Securities shall have the right to
cause the Company to purchase all or any part of the Securities of such Holder
at a repurchase price equal to 101% of the principal amount of the Securities to
be repurchased plus accrued interest to the date of repurchase (subject to the
right of holders of record on the

relevant record date to receive interest due on the related interest payment
date) as provided in, and subject to the terms of, the Indenture.

8.    Guarantee

      The payment by the Company of the principal of, and premium and interest
on, the Securities is fully and unconditionally guaranteed on a joint and
several senior basis by each of the Subsidiary Guarantors to the extent set
forth in the Indenture.

9.    Security

      The Securities shall be secured by the Collateral on the terms and subject
to the conditions set forth in the Indenture and the Security Documents, such
security interest to be second in priority to security interests granted for the
benefit of holders of First-Priority Lien Obligations. The Trustee and the
Collateral Agent, as the case may be, hold the Collateral in trust for the
benefit of the Trustee and the Holders, in each case pursuant to the Security
Documents and the Intercreditor Agreement. Each Holder, by accepting this
Security, consents and agrees to the terms of the Security Documents (including
the provisions providing for the foreclosure and release of Collateral) and the
Intercreditor Agreement as the same may be in effect or may be amended from time
to time in accordance with their terms and the Indenture and authorizes and
directs the Trustee and the Collateral Agent to enter into the Security
Documents and the Intercreditor Agreement, and to perform their respective
obligations and exercise their respective rights thereunder in accordance
therewith.

10.   Denominations; Transfer; Exchange

      The Securities are in registered form without coupons in denominations of
$1,000 principal amount and whole multiples of $1,000. A Holder may transfer or
exchange Securities in accordance with the Indenture. The Registrar may require
a Holder, among other things, to furnish appropriate endorsements or transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture. The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

11.   Persons Deemed Owners

      The registered Holder of this Security may be treated as the owner of it
for all purposes.

12.   Unclaimed Money

      If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Company
at its request unless an abandoned property law designates another Person. After
any such payment,

<PAGE>

                                                                               9

Holders entitled to the money must look only to the Company and not to the
Trustee for payment.

13.   Discharge and Defeasance

      Subject to certain conditions, the Company at any time shall be entitled
to terminate some or all of its obligations under the Securities and the
Indenture if the Company deposits with the Trustee money or U.S. Government
Obligations for the payment of principal and interest on the Securities to
redemption or maturity, as the case may be.

14.   Amendment; Waiver

      Subject to certain exceptions set forth in the Indenture, (1) the
Indenture and the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the Securities
and (2) any default or noncompliance with any provision may be waived with the
written consent of the Holders of a majority in principal amount outstanding of
the Securities. Subject to certain exceptions set forth in the Indenture,
without the consent of any Securityholder, the Company, the Subsidiary
Guarantors and the Trustee shall be entitled to amend the Indenture or the
Securities to cure any ambiguity, omission, defect or inconsistency, or to
comply with Article 5 of the Indenture, or to provide for uncertificated
Securities in addition to or in place of certificated Securities, or to add
guarantees with respect to the Securities, including Subsidiary Guaranties, or
to provide further security for the Securities, or to add additional covenants
or surrender rights and powers conferred on the Company or the Subsidiary
Guarantors, or to comply with any requirement of the SEC in connection with
qualifying the Indenture under the Act, or to make any change that does not
adversely affect the rights of any Securityholder, or to make amendments to
provisions of the Indenture relating to the form, authentication, transfer and
legending of the Securities, or in the event that such amendment is expressly
permitted pursuant to Section 11.01(b) of the Indenture or pursuant to the
Security Documents.

15.   Defaults and Remedies

      Under the Indenture, Events of Default include (a) default for 30 days in
payment of interest on the Securities; (b) default in payment of principal on
the Securities at maturity, upon redemption pursuant to paragraph 5 of the
Securities, upon acceleration or otherwise, or failure by the Company to
purchase Securities when required; (c) failure by the Company or any Subsidiary
Guarantor to comply with other agreements in the Indenture or the Securities, in
certain cases subject to notice and lapse of time; (d) certain accelerations
(including failure to pay within any grace period after final maturity) of other
Indebtedness of the Company, a Subsidiary Guarantor or any Significant
Subsidiary if the amount accelerated (or so unpaid) exceeds $10.0 million; (e)
certain events of bankruptcy or insolvency with respect to the Company, the
Subsidiary Guarantors and the Significant Subsidiaries; (f) certain judgments or
decrees for the payment of money in excess of $10.0 million; and (g) certain
defaults with respect to Subsidiary Guaranties; and (h) certain defaults with
respect to the Security Documents. If an Event of Default

<PAGE>

                                                                              10

occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the Securities may declare all the Securities to be due and
payable immediately. Certain events of bankruptcy or insolvency are Events of
Default which shall result in the Securities being due and payable immediately
upon the occurrence of such Events of Default.

      Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture. The Trustee may refuse to enforce the Indenture or
the Securities unless it receives indemnity or security satisfactory to it.
Subject to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Securityholders notice of any continuing Default
(except a Default in payment of principal or interest) if it determines that
withholding notice is in the interest of the Holders.

16.   Trustee Dealings with the Company

      Subject to certain limitations imposed by the Act, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

17.   No Recourse Against Others

      A director, officer, employee or stockholder, as such, of the Company or
the Trustee shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation. By accepting a Security,
each Securityholder waives and releases all such liability. The waiver and
release are part of the consideration for the issue of the Securities.

18.   Authentication

      This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

19.   Abbreviations

      Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

20.   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 Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Securities or
as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

21.   [Holders' Compliance with Registration Rights Agreement

      Each Holder of a Security, by acceptance hereof, acknowledges and agrees
to the provisions of the Registration Rights Agreement, including the
obligations of the Holders with respect to a registration and the
indemnification of the Company to the extent provided therein.](1)

beneficial owner as follows:

Name:__________________________

Address:_______________________

Taxpayer ID Number:____________

      The undersigned represents and warrants to you that:

      1. We are an institutional "accredited investor" (as defined in Rule
501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended (the
"Securities Act")), purchasing for our own account or for the account of such an
institutional "accredited investor" at least $250,000 principal amount of the
Securities, and we are acquiring the Securities not with a view to, or for offer
or sale in connection with, any distribution in violation of the Securities Act.
We have such knowledge and experience in financial and business matters as to be
capable of evaluating the merits and risks of our investment in the Securities,
and we invest in or purchase securities similar to the Securities in the normal
course of our business. We, and any accounts for which we are acting, are each
able to bear the economic risk of our or its investment.

      2. We understand that the Securities have not been registered under the
Securities Act and, unless so registered, may not be sold except as permitted in
the following sentence. We agree on our own behalf and on behalf of any investor
account for which we are purchasing Securities to offer, sell or otherwise
transfer such Securities prior to the date that is two years after the later of
the date of original issue and the last date on which the Company or any
affiliate of the Company was the owner of such Securities (or any predecessor
thereto) (the "Resale Restriction Termination Date") only (i) to the

Company, (ii) in the United States to a person whom the seller reasonably
believes is a qualified institutional buyer in a transaction meeting the

within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act
that is an institutional accredited investor purchasing for its own account or
for the account of an institutional accredited investor, in each case in a
minimum principal amount of the Securities of $250,000, (iv) outside the United
States in a transaction complying with the provisions of Rule 904 under the
Securities Act, (v) pursuant to an exemption from registration under the
Securities Act provided by Rule 144 (if available) or (vi) pursuant to an
effective registration statement under the Securities Act, in each of cases (i)
through (vi) subject to any requirement of law that the disposition of our
property or the property of such investor account or accounts be at all times
within our or their control and in compliance with any applicable state
securities laws. The foregoing restrictions on resale shall not apply subsequent
to the Resale Restriction Termination Date. If any resale or other transfer of
the Securities is proposed to be made pursuant to clause (iii) above prior to
the Resale Restriction Termination Date, the transferor shall deliver a letter
from the transferee substantially in the form of this letter to the Company and
the Trustee, which shall provide, among other things, that the transferee is an
institutional "accredited investor" within the meaning of Rule 501(a)(1), (2),
(3) or (7) under the Securities Act and that it is acquiring such Securities for
investment purposes and not for distribution in violation of the Securities Act.

Credit Suisse First Boston LLC
Morgan Stanley & Co. Incorporated
c/o Credit Suisse First Boston LLC
   Eleven Madison Avenue
   New York, New York 10010-3629

Dear Sirs:

     Securus Technologies, Inc., a Delaware corporation (the "Company"),
proposes to issue and sell to Credit Suisse First Boston LLC and Morgan Stanley
& Co. Incorporated (collectively, the "Initial Purchasers"), upon the terms set
forth in a purchase agreement of even date herewith (the "Purchase Agreement"),
$154,000,000 aggregate principal amount of its 11% Second-Priority Senior
Secured Notes due 2011 (the "Initial Securities"). The Initial Securities will
be issued pursuant to an Indenture, dated as of September 9, 2004, (the
"Indenture") among the Company, the Guarantors (as defined in the Purchase
Agreement) and The Bank of New York Trust Company, N.A. (the "Trustee"). As an
inducement to the Initial Purchasers, the Company agrees with the Initial
Purchasers, for the benefit of the holders of the Initial Securities (including,
without limitation, the Initial Purchasers), the Exchange Securities (as defined
below) and the Private Exchange Securities (as defined below) (collectively the
"Holders"), as follows:

     1. Registered Exchange Offer. The Company shall, at its own cost, prepare
and, not later than 200 days after (or if the 200th day is not a business day,
the first business day thereafter) the date of original issue of the Initial
Securities (the "Issue Date"), file with the Securities and Exchange Commission
(the "Commission") a registration statement (the "Exchange Offer Registration
Statement") on an appropriate form under the Securities Act of 1933, as amended
(the "Securities Act"), with respect to a proposed offer (the "Registered
Exchange Offer") to the Holders of Transfer Restricted Securities (as defined in
Section 6 hereof), who are not prohibited by any law or policy of the Commission
from participating in the Registered Exchange Offer, to issue and deliver to
such Holders, in exchange for the Initial Securities, a like aggregate principal
amount of debt securities (the "Exchange Securities") of the Company issued
under the Indenture and identical in all material respects to the Initial
Securities (except for the transfer restrictions relating to the Initial
Securities and the provisions relating to the matters described in Section 6
hereof) that would be registered under the Securities Act. The Company shall use
its reasonable best efforts to cause such Exchange Offer Registration Statement
to become effective under the Securities Act within 270 days (or if the 270th
day is not a business day, the first business day thereafter) after the Issue
Date of the Initial Securities and shall keep the Exchange Offer Registration
Statement effective for not less than 30 days (or longer, if required by
applicable law) after the date notice of the Registered Exchange Offer is mailed
to the Holders (such period being called the "Exchange Offer Registration
Period").

     If the Company effects the Registered Exchange Offer, the Company will be
entitled to close the Registered Exchange Offer 30 days after the commencement
thereof provided that the Company has accepted all the Initial Securities
theretofore validly tendered in accordance with the terms of the Registered
Exchange Offer.
<PAGE>
     Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities (as defined in Section 6
hereof) electing to exchange the Initial Securities for Exchange Securities
(assuming that such Holder is not an affiliate of the Company within the meaning
of the Securities Act, acquires the Exchange Securities in the ordinary course
of such Holder's business and has no arrangements with any person to participate
in the distribution of the Exchange Securities and is not prohibited by any law
or policy of the Commission from participating in the Registered Exchange Offer)
to trade such Exchange Securities from and after their receipt without any
limitations or restrictions under the Securities Act and without material
restrictions under the securities laws of the several states of the United
States.

     The Company acknowledges that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (i) each Holder which is a broker-dealer
electing to exchange Securities, acquired for its own account as a result of
market making activities or other trading activities, for Exchange Securities
(an "Exchanging Dealer"), is required to deliver a prospectus containing the
information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in
the "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer"
section, and (c) Annex C hereto in the "Plan of Distribution" section of such
prospectus in connection with a sale of any such Exchange Securities received by
such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) an
Initial Purchaser that elects to sell Exchange Securities acquired in exchange
for Securities constituting any portion of an unsold allotment is required to
deliver a prospectus containing the information required by Items 507 or 508 of
Regulation S-K under the Securities Act, as applicable, in connection with such
sale.

     The Company shall use its reasonable best efforts to keep the Exchange
Offer Registration Statement effective and to amend and supplement the
prospectus contained therein, in order to permit such prospectus to be lawfully
delivered by all persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such persons must comply with such
requirements in order to resell the Exchange Securities; provided, however, that
(i) in the case where such prospectus and any amendment or supplement thereto
must be delivered by an Exchanging Dealer or an Initial Purchaser, such period
shall be the lesser of 180 days and the date on which all Exchanging Dealers and
the Initial Purchasers have sold all Exchange Securities held by them (unless
such period is extended pursuant to Section 3(j) below) and (ii) the Company
shall make such prospectus and any amendment or supplement thereto, available to
any broker-dealer for use in connection with any resale of any Exchange
Securities for a period of not less than 90 days after the consummation of the
Registered Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities of the Company
issued under the Indenture and identical in all material respects (including the
existence of restrictions on transfer under the Securities Act and the
securities laws of the several states of the United States, but excluding
provisions relating to the matters described in Section 6 hereof) to the Initial
Securities (the "Private Exchange Securities"). The Initial Securities, the
Exchange Securities and the Private Exchange Securities are herein collectively
called the "Securities".

     In connection with the Registered Exchange Offer, the Company shall or
shall cause its agents to:

          (a) mail to each Holder a copy of the prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;

                                       2
<PAGE>
          (b) keep the Registered Exchange Offer open for not less than 30 days
     (or longer, if required by applicable law) after the date notice thereof is
     mailed to the Holders;

          (c) utilize the services of a depositary for the Registered Exchange
     Offer with an address in the Borough of Manhattan, The City of New York,
     which may be the Trustee or an affiliate of the Trustee;

          (d) permit Holders to withdraw tendered Securities at any time prior
     to the close of business, New York time, on the last business day on which
     the Registered Exchange Offer shall remain open; and

          (e) otherwise comply with all applicable laws in all material
     respects.

     As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Company shall:

          (x) accept for exchange all the Securities validly tendered and not
     withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

          (y) deliver to the Trustee for cancellation all the Initial Securities
     so accepted for exchange; and

          (z) cause the Trustee to authenticate and deliver promptly to each
     Holder of the Initial Securities, Exchange Securities or Private Exchange
     Securities, as the case may be, equal in principal amount to the Initial
     Securities of such Holder so accepted for exchange.

     The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the
Securities will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the date of original issue of the Initial
Securities.

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of the
Registered Exchange Offer (i) any Exchange Securities received by such Holder
will be acquired in the ordinary course of business, (ii) such Holder will have
no arrangements or understanding with any person to participate in the
distribution of the Securities or the Exchange Securities within the meaning of
the Securities Act, (iii) such Holder is not an "affiliate," as defined in Rule
405 of the Securities Act, of the Company or if it is an affiliate, such Holder
will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable, (iv) if such Holder is not a
broker-dealer, that it is not engaged in, and does not intend to engage in, the
distribution of the Exchange Securities and (v) if such Holder is a
broker-dealer, that it will receive Exchange Securities for its own account in
exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to
acknowledge that it will deliver a prospectus in connection with any resale of
such Exchange Securities.

     Notwithstanding any other provisions hereof, the Company will ensure that
(i) any Exchange Offer Registration Statement and any amendment thereto and any
prospectus forming part thereof and any

                                       3
<PAGE>
supplement thereto complies in all material respects with the Securities Act and
the rules and regulations thereunder, (ii) any Exchange Offer Registration
Statement and any amendment thereto does not, when it becomes effective, contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
and (iii) any prospectus forming part of any Exchange Offer Registration
Statement, and any supplement to such prospectus, does not include an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading.

     2. Shelf Registration. If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the Company
is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Registered Exchange Offer is not consummated within
300 days of the Issue Date, (iii) any Initial Purchaser so requests with respect
to the Initial Securities (or the Private Exchange Securities) not eligible to
be exchanged for Exchange Securities in the Registered Exchange Offer and held
by it following consummation of the Registered Exchange Offer or (iv) any Holder
(other than an Exchanging Dealer) is prohibited by law or Commission policy from
participating in the Registered Exchange Offer or, in the case of any Holder
(other than an Exchanging Dealer) that participates in the Registered Exchange
Offer, such Holder does not receive freely tradeable Exchange Securities on the
date of the exchange, the Company shall take the following actions:

          (a) The Company shall, at its cost, as promptly as practicable (but in
     no event more than 45 days after so required or requested pursuant to this
     Section 2) file with the Commission and thereafter shall use its reasonable
     best efforts to cause to be declared effective a registration statement
     (the "Shelf Registration Statement" and, together with the Exchange Offer
     Registration Statement, a "Registration Statement") on an appropriate form
     under the Securities Act relating to the offer and sale of the Transfer
     Restricted Securities (as defined in Section 6 hereof) by the Holders
     thereof from time to time in accordance with the methods of distribution
     set forth in the Shelf Registration Statement and Rule 415 under the
     Securities Act (hereinafter, the "Shelf Registration"); provided, however,
     that no Holder (other than an Initial Purchaser) shall be entitled to have
     the Securities held by it covered by such Shelf Registration Statement
     unless such Holder agrees in writing to be bound by all the provisions of
     this Agreement applicable to such Holder.

          (b) The Company shall use its reasonable best efforts to keep the
     Shelf Registration Statement continuously effective in order to permit the
     prospectus included therein to be lawfully delivered by the Holders of the
     relevant Securities, for a period of two years (or for such longer period
     if extended pursuant to Section 3(j) below) from the date of its
     effectiveness or such shorter period that will terminate when all the
     Securities covered by the Shelf Registration Statement (i) have been sold
     pursuant thereto or (ii) can be sold pursuant to Rule 144 under the
     Securities Act without any limitations under Rule 144. The Company shall be
     deemed not to have used its reasonable best efforts to keep the Shelf
     Registration Statement effective during the requisite period if it
     voluntarily takes any action that would result in Holders of Securities
     covered thereby not being able to offer and sell such Securities during
     that period, unless such action is required by applicable law.

          (c) Notwithstanding any other provisions of this Agreement to the
     contrary, the Company shall cause the Shelf Registration Statement and the
     related prospectus and any amendment or supplement thereto, as of the
     effective date of the Shelf Registration Statement, amendment or
     supplement, (i) to comply in all material respects with the applicable
     requirements of the Securities Act and the rules and regulations of the
     Commission and (ii) not to contain any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or necessary
     in order to make the statements therein, in light of the circumstances
     under which they were made, not misleading.

     3. Registration Procedures. In connection with any Shelf Registration
contemplated by Section 2 hereof and, to the extent applicable, any Registered
Exchange Offer contemplated by Section 1 hereof, the following provisions shall
apply:

          (a) The Company shall (i) furnish to each Initial Purchaser, prior to
     the filing thereof with the Commission, a copy of the Registration
     Statement and each amendment thereof and each supplement, if any, to the
     prospectus included therein and, in the event that an Initial Purchaser
     (with respect to any portion of an unsold allotment from the original
     offering) is participating in the Registered Exchange Offer or the Shelf
     Registration Statement, the Company shall use its best efforts to reflect
     in each such document, when so filed with the Commission, such comments as
     such Initial Purchaser reasonably may propose; (ii) include the information
     set forth in Annex A hereto on the cover, in Annex B hereto in the
     "Exchange Offer Procedures" section and the "Purpose of the Exchange Offer"
     section and in Annex C hereto in the "Plan of Distribution" section of the
     prospectus forming a part of the Exchange Offer Registration Statement and
     include the information set forth in Annex D hereto in the Letter of
     Transmittal delivered pursuant to the Registered Exchange Offer; (iii) if
     requested by an Initial Purchaser, include the information required by
     Items 507 or 508 of Regulation S-K under the Securities Act, as applicable,
     in the prospectus forming a part of the Exchange Offer Registration
     Statement; (iv) include within the prospectus contained in the Exchange
     Offer Registration Statement a section entitled "Plan of Distribution,"
     reasonably acceptable to the Initial Purchasers, which shall contain a
     summary statement of the positions taken or policies made by the staff of
     the Commission with respect to the potential "underwriter" status of any
     broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under
     the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of
     Exchange Securities received by such broker-dealer in the Registered
     Exchange Offer (a "Participating Broker-Dealer"), whether such positions or
     policies have been publicly disseminated by the staff of the Commission or
     such positions or policies, in the reasonable judgment of the Initial
     Purchasers based upon advice of counsel (which may be in-house counsel),
     represent the prevailing views of the staff of the Commission; and (v) in
     the case of a Shelf Registration Statement, include the names of the
     Holders, who propose to sell Securities pursuant to the Shelf Registration
     Statement, as selling securityholders.

          (b) The Company shall give written notice to the Initial Purchasers,
     the Holders of the Securities and any Participating Broker-Dealer from whom
     the Company has received prior written notice that it will be a
     Participating Broker-Dealer in the Registered Exchange Offer (which notice
     pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction
     to suspend the use of the prospectus until the requisite changes have been
     made):

               (i) when the Registration Statement or any amendment thereto has
          been filed with the Commission and when the Registration Statement or
          any post-effective amendment thereto has become effective;

               (ii) of any request by the Commission for amendments or
          supplements to the Registration Statement or the prospectus included
          therein or for additional information;

               (iii) of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

               (iv) of the receipt by the Company or its legal counsel of any
          notification with respect to the suspension of the qualification of
          the Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose; and

                                       5
<PAGE>
               (v) of the happening of any event that requires the Company to
          make changes in the Registration Statement or the prospectus in order
          that the Registration Statement or the prospectus do not contain an
          untrue statement of a material fact nor omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein (in the case of the prospectus, in light of the circumstances
          under which they were made) not misleading.

          (c) The Company shall make every reasonable effort to obtain the
     withdrawal at the earliest possible time, of any order suspending the
     effectiveness of the Registration Statement.

          (d) The Company shall furnish to each Holder of Securities included
     within the coverage of the Shelf Registration, without charge, at least one
     copy of the Shelf Registration Statement and any post-effective amendment
     thereto, including financial statements and schedules, and, if the Holder
     so requests in writing, all exhibits thereto (including those, if any,
     incorporated by reference).

          (e) The Company shall deliver to each Exchanging Dealer and each
     Initial Purchaser, and to any other Holder who so requests, without charge,
     at least one copy of the Exchange Offer Registration Statement and any
     post-effective amendment thereto, including financial statements and
     schedules, and, if any Initial Purchaser or any such Holder requests, all
     exhibits thereto (including those incorporated by reference).

          (f) The Company shall, during the Shelf Registration Period, deliver
     to each Holder of Securities included within the coverage of the Shelf
     Registration, without charge, as many copies of the prospectus (including
     each preliminary prospectus) included in the Shelf Registration Statement
     and any amendment or supplement thereto as such person may reasonably
     request. The Company consents, subject to the provisions of this Agreement,
     to the use of the prospectus or any amendment or supplement thereto by each
     of the selling Holders of the Securities in connection with the offering
     and sale of the Securities covered by the prospectus, or any amendment or
     supplement thereto, included in the Shelf Registration Statement.

          (g) The Company shall deliver to each Initial Purchaser, any
     Exchanging Dealer, any Participating Broker-Dealer and such other persons
     required to deliver a prospectus following the Registered Exchange Offer,
     without charge, as many copies of the final prospectus included in the
     Exchange Offer Registration Statement and any amendment or supplement
     thereto as such persons may reasonably request. The Company consents,
     subject to the provisions of this Agreement, to the use of the prospectus
     or any amendment or supplement thereto by any Initial Purchaser, if
     necessary, any Participating Broker-Dealer and such other persons required
     to deliver a prospectus following the Registered Exchange Offer in
     connection with the offering and sale of the Exchange Securities covered by
     the prospectus, or any amendment or supplement thereto, included in such
     Exchange Offer Registration Statement.

          (h) Prior to any public offering of the Securities, pursuant to any
     Registration Statement, the Company shall register or qualify or cooperate
     with the Holders of the Securities included therein and their respective
     counsel in connection with the registration or qualification of the
     Securities for offer and sale under the securities or "blue sky" laws of
     such states of the United States as any Holder of the Securities reasonably
     requests in writing and do any and all other acts or things necessary or
     advisable to enable the offer and sale in such jurisdictions of the
     Securities covered by such Registration Statement; provided, however, that
     the Company shall not be required to (i) qualify generally to do business
     in any jurisdiction where it is not then so qualified

                                       6
<PAGE>
     or (ii) take any action which would subject it to general service of
     process or to taxation in any jurisdiction where it is not then so subject.

          (i) The Company shall cooperate with the Holders of the Securities to
     facilitate the timely preparation and delivery of certificates representing
     the Securities to be sold pursuant to any Registration Statement free of
     any restrictive legends and in such denominations and registered in such
     names as the Holders may request a reasonable period of time prior to sales
     of the Securities pursuant to such Registration Statement.

          (j) Upon the occurrence of any event contemplated by paragraphs (ii)
     through (v) of Section 3(b) above during the period for which the Company
     is required to maintain an effective Registration Statement, the Company
     shall promptly prepare and file a post-effective amendment to the
     Registration Statement or a supplement to the related prospectus and any
     other required document so that, as thereafter delivered to Holders of the
     Securities or purchasers of Securities, the prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading.
     If the Company notifies the Initial Purchasers, the Holders of the
     Securities and any known Participating Broker-Dealer in accordance with
     paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the
     prospectus until the requisite changes to the prospectus have been made,
     then the Initial Purchasers, the Holders of the Securities and any such
     Participating Broker-Dealers shall suspend use of such prospectus, and the
     period of effectiveness of the Shelf Registration Statement provided for in
     Section 2(b) above and the Exchange Offer Registration Statement provided
     for in Section 1 above shall each be extended by the number of days from
     and including the date of the giving of such notice to and including the
     date when the Initial Purchasers, the Holders of the Securities and any
     known Participating Broker-Dealer shall have received such amended or
     supplemented prospectus pursuant to this Section 3(j).

          (k) Not later than the effective date of the applicable Registration
     Statement, the Company will provide a CUSIP number for the Initial
     Securities, the Exchange Securities or the Private Exchange Securities, as
     the case may be, and provide the applicable trustee with printed
     certificates for the Initial Securities, the Exchange Securities or the
     Private Exchange Securities, as the case may be, in a form eligible for
     deposit with The Depository Trust Company.

          (l) The Company will comply with all rules and regulations of the
     Commission to the extent and so long as they are applicable to the
     Registered Exchange Offer or the Shelf Registration and will make generally
     available to its security holders (or otherwise provide in accordance with
     Section 11(a) of the Securities Act) an earnings statement satisfying the
     provisions of Section 11(a) of the Securities Act, no later than 45 days
     after the end of a 12-month period (or 90 days, if such period is a fiscal
     year) beginning with the first month of the Company's first fiscal quarter
     commencing after the effective date of the Registration Statement, which
     statement shall cover such 12-month period.

          (m) The Company shall cause the Indenture to be qualified under the
     Trust Indenture Act of 1939, as amended, in a timely manner and containing
     such changes, if any, as shall be necessary for such qualification. In the
     event that such qualification would require the appointment of a new
     trustee under the Indenture, the Company shall appoint a new trustee
     thereunder pursuant to the applicable provisions of the Indenture.

          (n) The Company may require each Holder of Securities to be sold
     pursuant to the Shelf Registration Statement to furnish to the Company such
     information regarding the Holder and the distribution of the Securities as
     the Company may from time to time reasonably require for

                                       7
<PAGE>
     inclusion in the Shelf Registration Statement, and the Company may exclude
     from such registration the Securities of any Holder that unreasonably fails
     to furnish such information within a reasonable time after receiving such
     request.

          (o) The Company shall enter into such customary agreements (including,
     if requested, an underwriting agreement in customary form) and take all
     such other action, if any, as any Holder of the Securities shall reasonably
     request in order to facilitate the disposition of the Securities pursuant
     to any Shelf Registration.

          (p) In the case of any Shelf Registration, the Company shall (i) make
     reasonably available for inspection by the Holders of the Securities, any
     underwriter participating in any disposition pursuant to the Shelf
     Registration Statement and any attorney, accountant or other agent retained
     by the Holders of the Securities or any such underwriter all relevant
     financial and other records, pertinent corporate documents and properties
     of the Company and (ii) cause the Company's officers, directors, employees,
     accountants and auditors to supply all relevant information reasonably
     requested by the Holders of the Securities or any such underwriter,
     attorney, accountant or agent in connection with the Shelf Registration
     Statement, in each case, as shall be reasonably necessary to enable such
     persons, to conduct a reasonable investigation within the meaning of
     Section 11 of the Securities Act; provided, however, that the foregoing
     inspection and information gathering shall be coordinated on behalf of the
     Initial Purchasers by you and on behalf of the other parties, by one
     counsel designated by and on behalf of such other parties as described in
     Section 4 hereof provided further, however, that such persons shall first
     agree in writing with the Company that any information that is reasonably
     and in good faith designated by the Company in writing as confidential at
     the time of delivery of such information shall be kept confidential by such
     persons, unless (i) disclosure of such information is required by court or
     administrative order or is necessary to respond to inquiries of regulatory
     authorities, (ii) disclosure of such information is required by law
     (including any disclosure requirements pursuant to Federal securities laws
     in connection with the filing of any Registration Statement or the use of
     any laws in connection with the filing of any Registration Statement or the
     use of any Prospectus referred to in this Agreement), (iii) such
     information becomes generally available to the public other than as a
     result of a disclosure or failure to safeguard by any such person or (iv)
     such information becomes available to any such person from a source other
     than the Company and such source is not bound by a confidentiality
     agreement.

          (q) In the case of any Shelf Registration, the Company, if requested
     by any Holder of Securities covered thereby, shall cause (i) its counsel to
     deliver an opinion and updates thereof relating to the Securities in
     customary form addressed to such Holders and the managing underwriters, if
     any, thereof and dated, in the case of the initial opinion, the effective
     date of such Shelf Registration Statement (it being agreed that the matters
     to be covered by such opinion shall include, without limitation, the due
     incorporation and good standing of the Company and its subsidiaries; the
     qualification of the Company and its subsidiaries to transact business as
     foreign corporations; the due authorization, execution and delivery of the
     relevant agreement of the type referred to in Section 3(o) hereof; the due
     authorization, execution, authentication and issuance, and the validity and
     enforceability, of the applicable Securities; the absence of material legal
     or governmental proceedings involving the Company and its subsidiaries; the
     absence of governmental approvals required to be obtained in connection
     with the Shelf Registration Statement, the offering and sale of the
     applicable Securities, or any agreement of the type referred to in Section
     3(o) hereof; the compliance as to form of such Shelf Registration Statement
     and any documents incorporated by reference therein and of the Indenture
     with the requirements of the Securities Act and the Trust Indenture Act,
     respectively; and, as of the date of the opinion and as of the effective
     date of the Shelf Registration Statement or most recent post-effective
     amendment thereto, as the case may be, the absence from such Shelf
     Registration Statement and the prospectus

                                       8
<PAGE>
     included therein, as then amended or supplemented, and from any documents
     incorporated by reference therein of an untrue statement of a material fact
     or the omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading (in the
     case of any such documents, in the light of the circumstances existing at
     the time that such documents were filed with the Commission under the
     Exchange Act); (ii) its officers to execute and deliver all customary
     documents and certificates and updates thereof requested by any
     underwriters of the applicable Securities and (iii) its independent public
     accountants and the independent public accountants with respect to any
     other entity for which financial information is provided in the Shelf
     Registration Statement to provide to the selling Holders of the applicable
     Securities and any underwriter therefor a comfort letter in customary form
     and covering matters of the type customarily covered in comfort letters in
     connection with primary underwritten offerings, subject to receipt of
     appropriate documentation as contemplated, and only if permitted, by
     Statement of Auditing Standards No. 72.

          (r) In the case of the Registered Exchange Offer, if requested by any
     Initial Purchaser or any known Participating Broker-Dealer, the Company
     shall cause (i) its counsel to deliver to such Initial Purchaser or such
     Participating Broker-Dealer a signed opinion in the form set forth in
     Section 6(c) of the Purchase Agreement with such changes as are customary
     in connection with the preparation of a Registration Statement and (ii) its
     independent public accountants and the independent public accountants with
     respect to any other entity for which financial information is provided in
     the Registration Statement to deliver to such Initial Purchaser or such
     Participating Broker-Dealer a comfort letter, in customary form, meeting
     the requirements as to the substance thereof as set forth in Section 6(a)
     of the Purchase Agreement, with appropriate date changes.

          (s) If a Registered Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Initial Securities by Holders to the
     Company (or to such other Person as directed by the Company) in exchange
     for the Exchange Securities or the Private Exchange Securities, as the case
     may be, the Company shall mark, or caused to be marked, on the Initial
     Securities so exchanged that such Initial Securities are being canceled in
     exchange for the Exchange Securities or the Private Exchange Securities, as
     the case may be; in no event shall the Initial Securities be marked as paid
     or otherwise satisfied.

          (t) The Company will use its best efforts to (a) if the Initial
     Securities have been rated prior to the initial sale of such Initial
     Securities, confirm such ratings will apply to the Securities covered by a
     Registration Statement, or (b) if the Initial Securities were not
     previously rated, cause the Securities covered by a Registration Statement
     to be rated with the appropriate rating agencies, if so requested by
     Holders of a majority in aggregate principal amount of Securities covered
     by such Registration Statement, or by the managing underwriters, if any.

          (u) In the event that any broker-dealer registered under the Exchange
     Act shall underwrite any Securities or participate as a member of an
     underwriting syndicate or selling group or "assist in the distribution"
     (within the meaning of the Conduct Rules (the "Rules") of the National
     Association of Securities Dealers, Inc. ("NASD")) thereof, whether as a
     Holder of such Securities or as an underwriter, a placement or sales agent
     or a broker or dealer in respect thereof, or otherwise, the Company will
     assist such broker-dealer in complying with the requirements of such Rules,
     including, without limitation, by (i) if such Rules, including Rule 2720,
     shall so require, engaging a "qualified independent underwriter" (as
     defined in Rule 2720) to participate in the preparation of the Registration
     Statement relating to such Securities, to exercise usual standards of due
     diligence in respect thereto and, if any portion of the offering
     contemplated by such Registration Statement is an underwritten offering or
     is made through a placement or sales agent, to recommend the yield of such
     Securities, (ii) indemnifying any such qualified independent underwriter to
     the extent of the indemnification of underwriters provided in Section 5
     hereof and

                                       9
<PAGE>
     (iii) providing such information to such broker-dealer as may be reasonably
     required in order for such broker-dealer to comply with the requirements of
     the Rules.

          (v) The Company shall use its best efforts to take all other steps
     necessary to effect the registration of the Securities covered by a
     Registration Statement contemplated hereby.

     4. Registration Expenses. The Company shall bear all fees and expenses
incurred in connection with the performance of its obligations under Sections 1
through 3 hereof, whether or not the Registered Exchange Offer or a Shelf
Registration is filed or becomes effective, and, in the event of a Shelf
Registration, shall bear or reimburse the Holders of the Securities covered
thereby for the reasonable fees and disbursements of one firm of counsel
designated by the Holders of a majority in principal amount of the Initial
Securities covered thereby to act as counsel for the Holders of the Initial
Securities in connection therewith.

     5. Indemnification. (a) The Company agrees to indemnify and hold harmless
each Holder of the Securities, any Participating Broker-Dealer and each person,
if any, who controls such Holder or such Participating Broker-Dealer within the
meaning of the Securities Act or the Exchange Act (each Holder, any
Participating Broker-Dealer and such controlling persons are referred to
collectively as the "Indemnified Parties") from and against any losses, claims,
damages or liabilities, joint or several, or any actions in respect thereof
(including, but not limited to, any losses, claims, damages, liabilities or
actions relating to purchases and sales of the Securities) to which each
Indemnified Party may become subject under the Securities Act, the Exchange Act
or otherwise, insofar as such losses, claims, damages, liabilities or actions
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact contained in a Registration Statement or prospectus or in any
amendment or supplement thereto or in any preliminary prospectus relating to a
Shelf Registration, or arise out of, or are based upon, the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse, as
incurred, the Indemnified Parties for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action in respect thereof; provided, however, that
(i) the Company shall not be liable in any such case to the extent that such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration in reliance
upon and in conformity with written information pertaining to such Holder and
furnished to the Company by or on behalf of such Holder specifically for
inclusion therein and (ii) with respect to any untrue statement or omission or
alleged untrue statement or omission made in any preliminary prospectus relating
to a Shelf Registration Statement, the indemnity agreement contained in this
subsection (a) shall not inure to the benefit of any Holder or Participating
Broker-Dealer from whom the person asserting any such losses, claims, damages or
liabilities purchased the Securities concerned, to the extent that a prospectus
relating to such Securities was required to be delivered by such Holder or
Participating Broker-Dealer under the Securities Act in connection with such
purchase and any such loss, claim, damage or liability of such Holder or
Participating Broker-Dealer results from the fact that there was not sent or
given to such person, at or prior to the written confirmation of the sale of
such Securities to such person, a copy of the final prospectus if the Company
had previously furnished copies thereof to such Holder or Participating
Broker-Dealer; provided further, however, that this indemnity agreement will be
in addition to any liability which the Company may otherwise have to such
Indemnified Party. The Company shall also indemnify underwriters, their officers
and directors and each person who controls such underwriters within the meaning
of the Securities Act or the Exchange Act to the same extent as provided above
with respect to the indemnification of the Holders of the Securities if
requested by such Holders.

     (b) Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless the Company and each person, if any, who controls
the Company within the meaning of the Securities Act or the Exchange Act from
and against any losses, claims, damages or liabilities or any actions in respect

                                       10
<PAGE>
thereof, to which the Company or any such controlling person may become subject
under the Securities Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact necessary to make the statements therein not misleading, but in
each case only to the extent that the untrue statement or omission or alleged
untrue statement or omission was made in reliance upon and in conformity with
written information pertaining to such Holder and furnished to the Company by or
on behalf of such Holder specifically for inclusion therein; and, subject to the
limitation set forth immediately preceding this clause, shall reimburse, as
incurred, the Company for any legal or other expenses reasonably incurred by the
Company or any such controlling person in connection with investigating or
defending any loss, claim, damage, liability or action in respect thereof. This
indemnity agreement will be in addition to any liability which such Holder may
otherwise have to the Company or any of its controlling persons.

     (c) Promptly after receipt by an indemnified party under this Section 5 of
notice of the commencement of any action or proceeding (including a governmental
investigation), such indemnified party will, if a claim in respect thereof is to
be made against the indemnifying party under this Section 5, notify the
indemnifying party of the commencement thereof; but the failure to notify the
indemnifying party shall not relieve the indemnifying party from any liability
that it may have under subsection (a) or (b) above except to the extent that it
has been materially prejudiced (through the forfeiture of substantive rights or
defenses) by such failure; and provided further that the failure to notify the
indemnifying party shall not relieve it from any liability that it may have to
an indemnified party otherwise than under subsection (a) or (b) above. In case
any such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof the
indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement (i) includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action, and (ii) does not include a statement as to or an admission of
fault, culpability or a failure to act by or on behalf of any indemnified party.

     (d) If the indemnification provided for in this Section 5 is unavailable or
insufficient to hold harmless an indemnified party under subsections (a) or (b)
above, then each indemnifying party, in lieu of indemnifying such indemnified
person, shall contribute to the amount paid or payable by such indemnified party
as a result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to in subsection (a) or (b) above (i) in such proportion as is
appropriate to reflect the relative benefits received by the indemnifying party
or parties on the one hand and the indemnified party on the other from the
exchange of the Securities, pursuant to the Registered Exchange Offer, or (ii)
if the allocation provided by the foregoing clause (i) is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities (or actions in respect thereof) as well
as any other relevant equitable considerations. The relative fault of the
parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the

                                       11
<PAGE>
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or such Holder or such other indemnified
party, as the case may be, on the other, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid by an indemnified party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any action or claim which is the subject of this subsection (d).
Notwithstanding any other provision of this Section 5(d), the Holders of the
Securities shall not be required to contribute any amount in excess of the
amount by which the net proceeds received by such Holders from the sale of the
Securities pursuant to a Registration Statement exceeds the amount of damages
which such Holders have otherwise been required to pay by reason of such untrue
or alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this paragraph (d),
each person, if any, who controls such indemnified party within the meaning of
the Securities Act or the Exchange Act shall have the same rights to
contribution as such indemnified party and each person, if any, who controls the
Company within the meaning of the Securities Act or the Exchange Act shall have
the same rights to contribution as the Company.

     (e) The agreements contained in this Section 5 shall survive the sale of
the Securities pursuant to a Registration Statement and shall remain in full
force and effect so long as any Securities are outstanding, regardless of any
termination or cancellation of this Agreement or any investigation made by or on
behalf of any indemnified party.

     6. Additional Interest Under Certain Circumstances. (a) Additional interest
(the "Additional Interest") with respect to the Initial Securities shall be
assessed as follows if any of the following events occur (each such event in
clauses (i) through (iii) below a "Registration Default":

          (i) If by March 28, 2005, neither the Exchange Offer Registration
     Statement nor a Shelf Registration Statement has been filed with the
     Commission;

          (ii) If by July 6, 2005, neither the Registered Exchange Offer is
     consummated nor, if required in lieu thereof, the Shelf Registration
     Statement is declared effective by the Commission; or

          (iii) If after either the Exchange Offer Registration Statement or the
     Shelf Registration Statement is declared effective (A) such Registration
     Statement thereafter ceases to be effective; or (B) such Registration
     Statement or the related prospectus ceases to be usable (except as
     permitted in paragraph (b)) in connection with resales of Transfer
     Restricted Securities during the periods specified herein because either
     (1) any event occurs as a result of which the related prospectus forming
     part of such Registration Statement would include any untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein in the light of the circumstances under which they were
     made not misleading, or (2) it shall be necessary to amend such
     Registration Statement or supplement the related prospectus, to comply with
     the Securities Act or the Exchange Act or the respective rules thereunder.

Additional Interest shall accrue on the Initial Securities over and above the
interest set forth in the title of the Securities from and including the date on
which any such Registration Default shall occur to but excluding the date on
which all such Registration Defaults have been cured, at a rate of 0.50% per
annum for the first 90-day period immediately following the occurrence of a
Registration Default, and such rate will increase by an additional 0.50% per
annum with respect to each subsequent 90-day period until all Registration
Defaults have been cured, up to a maximum additional interest rate of 2.0% per
annum.

                                       12
<PAGE>
     (b) A Registration Default referred to in Section 6(a)(iii)(B) hereof shall
be deemed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Holders to use the related prospectus or (y) other material events, with respect
to the Company that would need to be described in such Shelf Registration
Statement or the related prospectus and (ii) in the case of clause (y), the
Company is proceeding promptly and in good faith to amend or supplement such
Shelf Registration Statement and related prospectus to describe such events;
provided, however, that in any case if such Registration Default occurs for a
continuous period in excess of 30 days, Additional Interest shall be payable in
accordance with the above paragraph from the day such Registration Default
occurs until such Registration Default is cured.

     (c) Any amounts of Additional Interest due pursuant to clause (i), (ii) or
(iii) of Section 6(a) above will be payable in cash on the regular interest
payment dates with respect to the Initial Securities. The amount of Additional
Interest will be determined by multiplying the applicable Additional Interest
rate by the principal amount of the Initial Securities, multiplied by a
fraction, the numerator of which is the number of days such Additional Interest
rate was applicable during such period (determined on the basis of a 360-day
year comprised of twelve 30-day months), and the denominator of which is 360.

     (d) "Transfer Restricted Securities" means each Security until (i) the date
on which such Transfer Restricted Security has been exchanged by a person other
than a broker-dealer for a freely transferable Exchange Security in the
Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the
Registered Exchange Offer of a Initial Security for an Exchange Note, the date
on which such Exchange Note is sold to a purchaser who receives from such
broker-dealer on or prior to the date of such sale a copy of the prospectus
contained in the Exchange Offer Registration Statement, (iii) the date on which
such Initial Security has been effectively registered under the Securities Act
and disposed of in accordance with the Shelf Registration Statement or (iv) the
date on which such Initial Securities is distributed to the public pursuant to
Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under
the Securities Act.

     7. Rules 144 and 144A. The Company shall use its reasonable best efforts to
file the reports required to be filed by it under the Securities Act and the
Exchange Act in a timely manner and, if at any time the Company is not required
to file such reports, it will, upon the request of any Holder of Initial
Securities, make publicly available other information so long as necessary to
permit sales of their securities pursuant to Rules 144 and 144A. The Company
covenants that it will take such further action as any Holder of Initial
Securities may reasonably request, all to the extent required from time to time
to enable such Holder to sell Initial Securities without registration under the
Securities Act within the limitation of the exemptions provided by Rules 144 and
144A (including the requirements of Rule 144A(d)(4)). The Company will provide a
copy of this Agreement to prospective purchasers of Initial Securities
identified to the Company by the Initial Purchasers upon request. Upon the
request of any Holder of Initial Securities, the Company shall deliver to such
Holder a written statement as to whether it has complied with such requirements.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company to register any of its securities pursuant to the Exchange
Act.

     8. Underwritten Registrations. If any of the Transfer Restricted Securities
covered by any Shelf Registration are to be sold in an underwritten offering,
the investment banker or investment bankers and manager or managers that will
administer the offering ("Managing Underwriters") will be selected by the
Company.

     No person may participate in any underwritten registration hereunder unless
such person (i) agrees to sell such person's Transfer Restricted Securities on
the basis reasonably provided in any underwriting

                                       13
<PAGE>
arrangements approved by the persons entitled hereunder to approve such
arrangements and (ii) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements.

     9. Miscellaneous.

     (a) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from

     Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. The Letter
of Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of Exchange Securities received in exchange for Initial Securities
where such Initial Securities were acquired by such broker-dealer as a result of
market-making activities or other trading activities. The Company has agreed
that, for a period of 180 days after the Expiration Date (as defined herein), it
will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See "Plan of Distribution."

                                                                         ANNEX B

     Each broker-dealer that receives Exchange Securities for its own account in
exchange for Securities, where such Initial Securities were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Securities. See "Plan of Distribution."
<PAGE>
                                                                         ANNEX C

                              PLAN OF DISTRIBUTION

     Each broker-dealer that receives Exchange Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of Exchange Securities received in
exchange for Initial Securities where such Initial Securities were acquired as a
result of market-making activities or other trading activities. The Company has
agreed that, for a period of 180 days after the Expiration Date, it will make
this prospectus, as amended or supplemented, available to any broker-dealer for
use in connection with any such resale. In addition, until [          ], all
dealers effecting transactions in the Exchange Securities may be required to
deliver a prospectus.(1)

     The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers. Exchange Securities received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities. Any broker-dealer that resells Exchange Securities that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act and any
profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that, by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     For a period of 180 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
