or on Schedule 3.1(c) attached hereto, as of the Effective Date, the Company is
not a party to, and it has no knowledge of, any agreement restricting the voting
or transfer of any shares of the capital stock of the Company. Except as set

attached hereto, the offer and sale of all capital stock, convertible

available to the Purchaser true and correct copies of the Company's Certificate
of Incorporation as in effect on the Effective Date (the "ARTICLES"), and the
Company's Bylaws as in effect on the Effective Date (the "BYLAWS").

          (d) ISSUANCE OF SHARES. The Shares to be issued under this Agreement
have been or will be (prior to issuance to the Purchaser hereunder) duly
authorized by all necessary corporate action and, when paid for or issued in
accordance with the terms hereof, the Shares shall be validly issued and
outstanding, fully paid and nonassessable, and the Purchaser shall be entitled
to all rights accorded to a holder of Common Stock.

          (e) NO CONFLICTS. The execution, delivery and performance of this
Agreement by the Company and the consummation by the Company of the transactions
contemplated herein do not (i) violate any provision of the Company's Articles
or Bylaws, (ii) conflict with, or constitute a default (or an event which with
notice or lapse of time or both would become a default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any
material agreement, mortgage, deed of trust, indenture, note, bond, license,
lease agreement, instrument or obligation to which the Company is a party, (iii)
create or impose

                                       7

a lien, charge or encumbrance on any property of the Company under any agreement
or any commitment to which the Company is a party or by which the Company is
bound or by which any of its respective properties or assets are bound, or (iv)
result in a violation of any federal, state, local or foreign statute, rule,
regulation, order, judgment or decree (including federal and state securities
laws and regulations) applicable to the Company or any of its subsidiaries or by
which any property or asset of the Company or any of its subsidiaries are bound
or affected, except, in all cases, for such conflicts, defaults, terminations,
amendments, acceleration, cancellations and violations as would not,
individually or in the aggregate, have a Material Adverse Effect. The Company is
not required under federal, state or local law, rule or regulation to obtain any
consent, authorization or order of, or make any filing or registration with, any
court or governmental agency in order for it to execute, deliver or perform any
of its obligations under this Agreement, or issue and sell the Shares to the
Purchaser in accordance with the terms hereof (other than any filings which may
be required to be made by the Company with the Commission or Nasdaq subsequent
to the Closing and any registration statement which has been or may be filed
pursuant hereto); provided, however, that, for purpose of the representation
made in this sentence, the Company is assuming and relying upon the accuracy of
the representations, warranties and agreements of the Purchaser herein.

          (f) COMMISSION DOCUMENTS, FINANCIAL STATEMENTS. The Common Stock is
registered pursuant to Section 12(b) or 12(g) of the Exchange Act and, except as

3.1(f) attached hereto, as of the Effective Date the Company has timely filed
all Commission Documents. The Company has delivered or made available to the
Purchaser true and complete copies of the Commission Documents filed with the
Commission since December 31, 1999 and prior to the Effective Date. The Company
has not provided to the Purchaser any information which, according to applicable
law, rule or regulation, should have been disclosed publicly by the Company but

contemplated by this Agreement. As of its date, the 1999 Form 10-K/A complied in
all material respects with the requirements of the Exchange Act and other
federal, state and local laws, rules and regulations applicable to it, and, as
of its date, such Form 10-K/A did not 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. The financial statements of the Company
included in the Commission Documents comply as to form in all material respects
with applicable accounting requirements and the published rules and regulations
of the Commission or other applicable rules and regulations with respect
thereto. Such financial statements have been prepared in accordance with GAAP
applied on a consistent basis during the periods involved (except (i) as may be
otherwise indicated in such financial statements or the notes thereto or (ii) in
the case of unaudited interim statements, to the extent they may not include
footnotes or may be condensed or summary statements), and fairly present in all
material respects the financial position of the Company and its subsidiaries as

periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments).

          (g) SUBSIDIARIES. The Commission Documents, the Commission Filings or
Schedule 3.1(g) attached hereto set forth each subsidiary of the Company as of

the Company's ownership of the outstanding stock or other interests of such
subsidiary. For the purposes of this Agreement, "subsidiary" shall mean any
corporation or other entity of which at least a majority of the securities or
other ownership interest having ordinary voting power (absolutely or
contingently) for the election of directors or other persons performing similar
functions are at the time owned directly or indirectly by the Company and/or any
of its other subsidiaries. Except as set forth in the Commission Documents or
the Commission Filings, none of such subsidiaries is a "significant subsidiary"
as defined in Regulation S-X.

          (h) NO MATERIAL ADVERSE EFFECT OR MATERIAL CHANGE IN OWNERSHIP. Since
the Effective Date, the Company has not experienced or suffered any Material
Adverse Effect except continued losses from operations, or any Material Change
in Ownership.

          (i) NO UNDISCLOSED LIABILITIES. Except as disclosed in the Commission
Documents, the Commission Filings or on Schedule 3.1(i) attached hereto, neither
the Company nor any of its subsidiaries has any liabilities, obligations, claims
or losses (whether liquidated or unliquidated, secured or unsecured, absolute,
accrued, contingent or otherwise) that would be required to be disclosed on a
balance sheet of the Company or any subsidiary (including the notes thereto) in
conformity with GAAP and are not disclosed in the Commission Documents or
Commission Filings, other than those incurred in the ordinary course of the
Company's or its subsidiaries respective businesses since March 31, 2000 and
which, individually or in the aggregate, do not or would not have a Material
Adverse Effect.

          (j) NO UNDISCLOSED EVENTS OR CIRCUMSTANCES. No event or circumstance
has occurred or exists with respect to the Company or its subsidiaries or their
respective businesses, properties, prospects, operations or financial condition,
which, under applicable law, rule or regulation, requires public disclosure or
announcement by the Company but which has not been so publicly announced or
disclosed, except for events or circumstances which, individually or in the
aggregate, do not or would not have a Material Adverse Effect.

          (k) INDEBTEDNESS. The Commission Documents or Commission Filings as of
March 31, 2000 set forth all outstanding secured and unsecured Indebtedness of
the Company or any subsidiary, or for which the Company or any subsidiary has
commitments through such date. For the purposes of this Agreement,
"INDEBTEDNESS" shall mean (a) any liabilities for borrowed money or amounts owed
in excess of $1,000,000 (other than trade accounts payable incurred in the
ordinary course of business), (b) all guaranties, endorsements and other
contingent obligations in respect of Indebtedness of others, whether or not the
same are or should be reflected in the Company's balance sheet (or the notes
thereto), except guaranties by endorsement of negotiable instruments for deposit
or collection or similar transactions in the ordinary course of business; and
(c) the present value of any lease payments in excess of $1,000,000 due under
leases required to be capitalized in accordance with GAAP. Neither the Company
nor any subsidiary is in default with respect to any Indebtedness.

          (l) TITLE TO ASSETS. Each of the Company and its subsidiaries has good

reflected in the Commission Documents or the Commission Filings, free of any
mortgages, pledges, charges, liens, security interests or other encumbrances,
except for those indicated in the Commission Documents, the

                                       9
<PAGE>

Commission Filings or on Schedule 3.1(l) attached hereto or those that do not or
would not have a Material Adverse Effect. All said real property leases of the
Company are valid and subsisting and in full force and effect in all material
respects.

          (m) ACTIONS PENDING. There is no action, suit, claim, investigation or
proceeding pending or, to the knowledge of the Company, threatened against the
Company or any subsidiary which questions the validity of this Agreement or the
transactions contemplated hereby or any action taken or to be taken pursuant
hereto or thereto. Except as set forth in the Commission Documents, the
Commission Filings or on Schedule 3.1(m) attached hereto, there is no action,
suit, claim, investigation or proceeding pending or, to the knowledge of the
Company, threatened, against or involving the Company, any subsidiary or any of
their respective properties or assets and which, if determined adversely to the
Company or its subsidiary, would have a Material Adverse Effect.

          (n) COMPLIANCE WITH LAW. The business of the Company and the
subsidiaries has been and is presently being conducted in all material respects
in accordance with all applicable federal, state and local governmental laws,
rules, regulations and ordinances, except as set forth in the Commission

except as, individually or in the aggregate, do not or would not have a Material
Adverse Effect. The Company and each of its subsidiaries have all franchises,
permits, licenses, consents and other governmental or regulatory authorizations
and approvals necessary for the conduct of its business as now being conducted
by it, except where the failure to possess such franchises, permits, licenses,
consents and other governmental or regulatory authorizations and approvals,
individually or in the aggregate, do not or would not have a Material Adverse
Effect.

          (o) CERTAIN FEES. No brokers, finders or financial advisory fees or
commissions will be payable by the Company or any subsidiary with respect to the
transactions contemplated by this Agreement.

          (p) DISCLOSURE. To the best of the Company's knowledge, neither this
Agreement or the Schedules hereto nor any other documents, certificates or
instruments furnished to the Purchaser by or on behalf of the Company or any
subsidiary in connection with the transactions contemplated by this Agreement
contain any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements made herein or therein, in the
light of the circumstances under which they were made herein or therein, not
misleading.

          (q) OPERATION OF BUSINESS. The Company or one or more of its
subsidiaries owns or controls all patents, trademarks, service marks, trade
names, copyrights, licenses and authorizations as set forth in the Commission
Documents, the Commission Filings or on Schedule 3.1(q) attached hereto, and all
rights with respect to the foregoing, which are necessary for the conduct of its
business as now conducted without, to the Company's knowledge, any conflict with

or the Commission Filings and except to the extent that any such conflict would
not have a Material Adverse Effect.

                                       10
<PAGE>

          (r) ENVIRONMENTAL COMPLIANCE. Except as disclosed in the Commission
Documents, Commission Filings or on Schedule 3.1(r) attached hereto, the Company
and each of its subsidiaries have obtained all material approvals,
authorization, certificates, consents, licenses, orders and permits or other
similar authorizations of all governmental authorities, or from any other
person, that are required under any Environmental Laws, except for any
approvals, authorization, certificates, consents, licenses, orders and permits
or other similar authorizations the failure of which to obtain does not or would
not have a Material Adverse Effect. "ENVIRONMENTAL LAWS" shall mean all
applicable laws relating to the protection of the environment including, without
limitation, all requirements pertaining to reporting, licensing, permitting,
controlling, investigating or remediating emissions, discharges, releases or
threatened releases of hazardous substances, chemical substances, pollutants,
contaminants or toxic substances, materials or wastes, whether solid, liquid or
gaseous in nature, into the air, surface water, groundwater or land, or relating
to the manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of hazardous substances, chemical substances, pollutants,
contaminants or toxic substances, material or wastes, whether solid, liquid or
gaseous in nature. Except for such instances as would not individually or in the
aggregate have a Material Adverse Effect, to the best of the Company's
knowledge, there are no past or present events, conditions, circumstances,
incidents, actions or omissions relating to or in any way affecting the Company
or its subsidiaries that violate or could reasonably be expected to violate any
Environmental Law after the Closing or that could reasonably be expected to give
rise to any environmental liability, or otherwise form the basis of any claim,
action, demand, suit, proceeding, hearing, study or investigation (i) under any
Environmental Law, or (ii) based on or related to the manufacture, processing,
distribution, use, treatment, storage (including without limitation underground
storage tanks), disposal, transport or handling, or the emission, discharge,
release or threatened release of any hazardous substance.

          (s) MATERIAL AGREEMENTS. Except as set forth in the Commission
Documents, the Commission Filings or on Schedule 3.1(s) attached hereto, neither
the Company nor any subsidiary of the Company is a party to any written or oral
contract, instrument, agreement, commitment, obligation, plan or arrangement, a
copy of which would be required to be filed with the Commission as an exhibit to
a registration statement on Form S-3 or applicable form (collectively, "MATERIAL
AGREEMENTS") if the Company or any subsidiary were registering securities under
the Securities Act. The Company and each of its subsidiaries has in all material
respects performed all the obligations required to be performed by them to date
under the Material Agreements, have received no notice of default by the Company
thereunder and, to the best of the Company's knowledge, are not in default under
any Material Agreement now in effect, the result of which would have a Material
Adverse Effect.

          (t) TRANSACTIONS WITH AFFILIATES. Except as set forth in the
Commission Documents, the Commission Filings or on Schedule 3.1(t) attached
hereto, there are no loans, leases, agreements, contracts, royalty agreements,
management contracts or arrangements or other continuing transactions exceeding
$1,000,000 between (a) the Company or any subsidiary, on the one hand, and (b)
on the other hand, any officer, employee or director of the Company, or any of
its subsidiaries, or any person who would be covered by Item 404(a) of
Regulation S-K or any corporation or other entity controlled by such officer,
employee, director or person.

with all applicable federal and state securities laws in connection with the

               (i) Each Prospectus included as part of the Rule 429 Registration
Statement or as part of any amendment or supplement thereto, or filed pursuant
to Rule 424 under the Securities Act, will comply when so filed in all material
respects with the provisions of the Securities Act. The Commission has not

              (ii) The Company meets the requirements for the use of Form S-3
under the Securities Act. The Rule 429 Registration Statement in the form in
which it will become effective and also in such form as it may be amended or
supplemented from time to time, and the Prospectus and any supplement or
amendment thereto when filed with the Commission under Rule 424(b) under the
Securities Act, will comply in all material respects with the provisions of the
Securities Act and will not at any such time 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 in the light of the circumstances under
which they are made, not misleading, except that this representation and
warranty does not apply to statements in or omissions from the Rule 429
Registration Statement or the Prospectus made in reliance upon and in conformity
with information relating to the Purchaser furnished to the Company in writing
by or on behalf of the Purchaser expressly for use therein.

             (iii) The Company has not distributed and, prior to the
completion of the distribution of the Shares, will not distribute any offering

Commission Documents, the Commission Filings or Schedule 3.1(v), no officer,
consultant or key employee of the Company or any subsidiary whose termination,
either individually or in the aggregate, would have a Material Adverse Effect,

terminating his or her employment or engagement with the Company or any
subsidiary.

          (w) USE OF PROCEEDS. The proceeds from the sale of the Shares will be
used by the Company and its subsidiaries as set forth in the Registration
Statement.

          (x) PUBLIC UTILITY HOLDING COMPANY ACT AND INVESTMENT COMPANY ACT
STATUS. The Company is not a "holding company" or a "public utility company" as
such terms are defined in the Public Utility Holding Company Act of 1935, as
amended. The Company is not, and as a result of and immediately upon Closing
will not be, an "investment company" or a

                                       12

<PAGE>

company "controlled" by an "investment company," within the meaning of the

          (y) ERISA. No liability to the Pension Benefit Guaranty Corporation
has been incurred with respect to any Plan by the Company or any of its
subsidiaries which is or would have a Material Adverse Effect. The execution and
delivery of this Agreement and the issue and sale of the Shares will not involve
any transaction which is subject to the prohibitions of Section 406 of ERISA or
in connection with which a tax could be imposed pursuant to Section 4975 of the
Internal Revenue Code of 1986, as amended. As used in this Section 3.1(y), the
term "Plan" shall mean an "employee pension benefit plan" (as defined in Section
3 of ERISA) which is or has been established or maintained, or to which
contributions are or have been made, by the Company or any subsidiary or by any
trade or business, whether or not incorporated, which, together with the Company
or any subsidiary, is under common control, as described in Section 414(b) or
(c) of the Code.

          (z) ACKNOWLEDGMENT REGARDING PURCHASER'S PURCHASE OF SHARES. The
Company acknowledges and agrees that the Purchaser is acting solely in the
capacity of an arm's length purchaser with respect to this Agreement and the
transactions contemplated hereunder. The Company further acknowledges that the
Purchaser is not acting as a financial advisor or fiduciary of the Company (or
in any similar capacity) with respect to this Agreement and the transactions
contemplated hereunder and any advice given by the Purchaser or any of its
representatives or agents in connection with this Agreement and the transactions
contemplated hereunder is merely incidental to the Purchaser's purchase of the
Shares.

     Section 3.2 REPRESENTATIONS AND WARRANTIES OF THE PURCHASER. The Purchaser
hereby makes the following representations and warranties to the Company:

          (a) ORGANIZATION AND STANDING OF THE PURCHASER. The Purchaser is an
international business company duly incorporated, validly existing and in good
standing under the laws of the Commonwealth of The Bahamas.

          (b) AUTHORIZATION AND POWER. The Purchaser has the requisite corporate
power and authority to enter into and perform this Agreement and to purchase the
Shares in accordance with the terms hereof. The execution, delivery and
performance of this Agreement by Purchaser and the consummation by it of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action, and no further consent or authorization of the Purchaser, its
Board of Directors or stockholders is required. This Agreement has been duly
executed and delivered by the Purchaser. This Agreement constitutes, or shall
constitute when executed and delivered, a valid and binding obligation of the
Purchaser enforceable against the Purchaser in accordance with its terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, liquidation, conservatorship, receivership, or
similar laws relating to, or affecting generally the enforcement of, creditor's
rights and remedies or by other equitable principles of general application.

          (c) NO CONFLICTS. The execution, delivery and performance of this
Agreement and the consummation by the Purchaser of the transactions contemplated
hereby and thereby or

                                       13
<PAGE>

relating hereto do not and will not (i) result in a violation of such
Purchaser's charter documents or bylaws or (ii) conflict with, or constitute a
default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment,
acceleration or cancellation of, any material agreement, mortgage, deed of
trust, indenture, note, bond, license, lease agreement, instrument or obligation
to which the Purchaser is a party, (iii) create or impose or lien, charge or
encumbrance on any property of the Purchaser under any agreement or any
commitment to which the Purchaser is party or by which the Purchaser is bound or
by which any of its respective properties or assets are bound, or (iv) result in
a violation of any law, rule, or regulation, or any order, judgment or decree of
any court or governmental agency applicable to the Purchaser or its properties,
except for such conflicts, defaults and violations as would not, individually or
in the aggregate, prohibit or otherwise interfere with the ability of the
Purchaser to enter into and perform its obligations under this Agreement in any
material respect. The Purchaser is not required to obtain any consent,
authorization or order of, or make any filing or registration with, any court or
governmental agency in order for it to execute, deliver or perform any of its
obligations under this Agreement or to purchase the Shares in accordance with
the terms hereof; provided, however, that for purposes of the representation
made in this sentence, the Purchaser is assuming and relying upon the accuracy
of the representations, warranties and agreements of the Company herein.

furnished with all materials relating to the business, finances and operations
of the Company and materials relating to the offer and sale of the Shares which
have been requested by the Purchaser. The Purchaser and its advisors, if any,
have been afforded the opportunity to ask questions of the Company. The
Purchaser has sought such accounting, legal and tax advice as it has considered
necessary to make an informed investment decision with respect to its
acquisition of the Shares. The Purchaser understands that it (and not the
Company) shall be responsible for its own tax liabilities that may arise as a
result of this investment or the transactions contemplated by this Agreement.

          (e) CARLIN EQUITIES CORP. The Purchaser used Carlin Equities Corp.
("CARLIN") as its broker-dealer to effectuate all sales, if any, of the shares
of the Company's Common Stock purchased from the Company in September 2000,
October 2000, November 2000 and February 2001 and the Purchaser intends to use
Carlin as its broker-dealer to sell any other shares of Common Stock that it may
purchase from the Company. Carlin is not an affiliate of the Purchaser and will
receive commissions from the Purchaser which will not exceed customary brokerage
commissions.

the reset of the purchase price of the Common Stock to below the then current

     Section 4.9 STOP ORDERS. The Company will advise the Purchaser promptly
and, if requested by the Purchaser, will confirm such advice in writing: (i) of
the Company's receipt of notice of any request by the Commission for amendment
of or a supplement to the Registration Statement, any Prospectus or for
additional information; (ii) of the Company's receipt of notice of the issuance
by the Commission of any stop order suspending the effectiveness of the

offering or sale in

                                       16

any jurisdiction or the initiation of any proceeding for such purpose; and (iii)
of the Company becoming aware of the happening of any event, which makes any
statement of a material fact made in the Rule 429 Registration Statement or the
Prospectus (as then amended or supplemented) untrue or which requires the making
of any additions to or changes in the Rule 429 Registration Statement or the
Prospectus (as then amended or supplemented) in order to state a material fact
required by the Securities Act to be stated therein or necessary in order to
make the statements therein not misleading, or of the necessity to amend or
supplement the Prospectus (as then amended or supplemented) to comply with the
Securities Act or any other law. If at any time the Commission shall issue any
stop order suspending the effectiveness of the Registration Statement, the
Company will make commercially reasonable efforts to obtain the withdrawal of

file any amendment to the Rule 429 Registration Statement that relates to the
Purchaser, this Agreement or the transactions contemplated hereby or make any
amendment or supplement to the Prospectus that relates to the Purchaser, this
Agreement or the transactions contemplated hereby of which the Purchaser shall
not previously have been advised or to which the Purchaser shall reasonably
object after being so advised unless it is necessary to amend the Rule 429
Registration Statement or make any amendment or supplement to the Prospectus to
comply with the Securities Act or any other applicable law or regulation, in
which case the Company shall expeditiously furnish to the Purchaser a reasonable
number of copies thereof. In addition, for so long as, in the reasonable opinion
of counsel for the Purchaser and counsel for the Company, a Prospectus is
required to be delivered in connection with any purchase of Shares by the
Purchaser, the Company will not file any Prospectus or Prospectus supplement
with respect to the Shares without delivering a copy of such Prospectus or
Prospectus supplement to the Purchaser promptly following such filing. It is
understood that the Company may file amendments to the Rule 429 Registration
Statement and make amendments and supplements to the Prospectus in connection
with offerings pursuant to the Rule 429 Registration Statement to parties other
than the Purchaser, and that such amendments and supplements shall not be
covered by the first two (2) sentences of this Section 4.10.

     Section 4.11 PROSPECTUS DELIVERY. The Company shall file with the
Commission a Prospectus supplement on the first Trading Day immediately
following the end of each Draw Down Pricing Period, and will deliver to the
Purchaser, without charge, in such quantities as reasonably requested by the
Purchaser, copies of each form of Prospectus and Prospectus supplement on each
Settlement Date. The Company consents to the use of the Prospectus (and of any
amendment or supplement thereto) in accordance with the provisions of the
Securities Act and with the securities or Blue Sky laws of the jurisdictions in
which the Shares may be sold by the Purchaser, in connection with the offering
and sale of the Shares and for such period of time thereafter as the Prospectus
is required by the Securities Act to be delivered in connection with sales of
the Shares. If during such period of time any event shall occur that in the
judgment of the Company and its counsel or in the opinion of counsel for the
Purchaser is required to be set forth in the Prospectus (as then amended or
supplemented) or should be set forth therein in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or if it is necessary to supplement or amend the Prospectus to
comply with the Securities Act or any other applicable law or regulation, the
Company will forthwith prepare and,

                                       17
<PAGE>

subject to Section 4.9 above, file with the Commission an appropriate supplement
or amendment to such Prospectus, and will expeditiously furnish to the Purchaser
a reasonable number of copies thereof.

managed by the Purchaser or any affiliate of the Purchaser or any entity managed
by the Purchaser, except that the Purchaser may sell Shares that it has not yet
taken delivery of pursuant to the provisions of a Draw Down Notice so long as
the Purchaser covers any such sales with the Shares purchased pursuant to such
Draw Down Notice. Prior to, during the Investment Period and for a period of
three (3) months after the termination of this Agreement, the Purchaser shall
not grant any option to purchase or acquire any right to dispose or otherwise
dispose for value of any shares of Common Stock or any securities convertible
into, or exchangeable for, or warrants to purchase, any shares of Common Stock,
or enter into any swap, hedge or other agreement that transfers, in whole or in
part, the economic risk of ownership of the Common Stock, except for such sales
permitted by the preceding two sentences. In addition, on a daily Trading Day
basis, the Purchaser agrees to restrict the volume of sales of Shares by the
Purchaser, its affiliates and any entity managed by the Purchaser to no more
than twenty percent (20%) of the total trading volume of the Common Stock, as
reported on Bloomberg Financial LP using HP function, for such Trading Day.

          (b) In addition to the foregoing, in connection with any sale of the
Company's securities (including any short sale permitted by the preceding
paragraph), the Purchaser shall comply in all respects with all applicable laws,
rules, regulations and orders, including, without limitation, the requirements
of the Securities Act and the Exchange Act, including, without limitation, Rule
415(a)(4) under the Securities Act and Regulation M and Rule 10b-5 under the
Exchange Act.

                                   ARTICLE VI

                          DRAW DOWN TERMS; CALL OPTION

     Section 6.1 DRAW DOWN TERMS. Subject to the satisfaction of the conditions
set forth in this Agreement, and subject to Section 6.3 below, the parties agree
as follows:

          (a) The Company may, in its sole discretion, issue a Draw Down Notice
(as defined in Section 6.1(j) hereof) for a specified Draw Down Amount Requested
of up to (i) $6,000,000 if the Threshold Price for the Draw Down Amount as set
forth in such Draw Down Notice is equal to or greater than $20.00 and less than
$35.00, (ii) $8,000,000 if the Threshold Price for the Draw Down Amount as set
forth in such Draw Down Notice is equal to or greater than $35.00 or (iii) such
other amount mutually agreed upon by the Purchaser and the Company, which Draw
Down the Purchaser will be obligated to accept. The date the Company issues any
Draw Down Notice in accordance with this Section 6.1 shall be a "Draw Down
Exercise Date" for purposes of this Agreement.

          (b) Subject to Section 6.1(i) below, the number of Shares to be issued
by the Company to the Purchaser in connection with each Draw Down shall be equal
to the sum of the quotients (for each Trading Day of the Draw Down Pricing
Period for which the VWAP equals or exceeds the Threshold Price) of (x) 1/18th
(or such other fraction based on the length of the Draw Down Pricing Period) of
the Draw Down Amount divided by (y) the specified percentage of the VWAP set
forth in Section 6.1(k) hereof or such other percentage mutually agreed upon by
the Purchaser and the Company (the "DRAW DOWN DISCOUNT PRICE") of the Common
Stock.

          (c) Only one Draw Down shall be allowed in each Draw Down Pricing
Period.

          (d) Each Draw Down shall be settled on the second Trading Day after
the end of each Draw Down Pricing Period (the "SETTLEMENT DATE").

          (e) There shall be a minimum of five (5) Trading Days between the end
of a Draw Down Pricing Period and the commencement of the next Draw Down Pricing
Period, unless otherwise mutually agreed upon between the Purchaser and the
Company.

          (f) There shall be a maximum of thirty-six (36) Draw Downs during the
Investment Period.

          (g) At the end of each Draw Down Pricing Period, the Purchaser's total
Draw Down commitment under this Agreement (which equals $149,000,000 as of the
Effective Date) shall be reduced by the total amount of the Draw Down Amount and
the Call Option Amount, if any, for such Draw Down Pricing Period.

                                       22
<PAGE>

          (h) Each Draw Down will automatically expire immediately after the
last Trading Day of each Draw Down Pricing Period.

          (i) If the VWAP on a given Trading Day in the Draw Down Pricing Period
is less than the Threshold Price, then the total amount of the Draw Down Amount
Requested will be reduced by 1/18th (or such other fraction based on the length
of the Draw Down Pricing Period) and no Shares will be purchased or sold with
respect to such Trading Day, except as provided below. At no time shall the
Threshold Price be set below twenty dollars ($20.00) unless agreed upon by the
Company and the Purchaser. If trading in the Common Stock is suspended for any
reason for more than three (3) hours in any Trading Day, the price of the Common
Stock may, at the Purchaser's option, be deemed to be below the Threshold Price
for that Trading Day. For each Trading Day during a Draw Down Pricing Period
that the VWAP is below the Threshold Price, the Purchaser may elect in its sole
discretion to purchase the Common Stock at the Threshold Price multiplied by the
applicable percentage set forth in Section 6.1(k) at the end of such Draw Down
Pricing Period. The Purchaser will inform the Company via facsimile transmission
no later than 8:00 p.m. (New York time) on the last Trading Day of such Draw
Down Pricing Period as to the number of Shares, if any, the Purchaser chooses to
purchase under such circumstances.

          (j) As a condition to exercise of any Draw Down, the Company must
provide a notice to the Purchaser of the Company's exercise of any Draw Down via
facsimile transmission before commencement of trading on the first Trading Day
of the Draw Down Pricing Period covered by such notice (the "DRAW DOWN NOTICE"),
substantially in the form attached hereto as Exhibit D. The Draw Down Notice
shall specify the Draw Down Amount Requested, set the Threshold Price for such
Draw Down, designate the first Trading Day of the Draw Down Pricing Period and
specify the Call Option(s), if any, that the Company wishes to grant to the
Purchaser during the Draw Down Pricing Period and the applicable Threshold Price
for such Call Option (the "CALL OPTION THRESHOLD PRICE"). Unless the Company and
the Purchaser mutually agree otherwise, at no time shall the Purchaser be
required to purchase more than $8,000,000 of the Common Stock for a given Draw
Down Pricing Period (excluding the Common Stock purchased pursuant to a Call
Option).

          (k) With respect to any Draw Down, if the Market Capitalization is
equal to or above $1 billion, the Draw Down Discount Price shall be 96.00% of
the VWAP. If the Market Capitalization is below $1 billion and equal to or above
$750 million, the Draw Down Discount Price shall be 95.50% of the VWAP. If the
Market Capitalization is below $750 million and equal to or above $500 million,
the Draw Down Discount Price shall be 95.00% of the VWAP. From $500 million to
$300 million, for each $100 million decrease in Market Capitalization, the Draw
Down Discount Price shall be decreased by 0.50% incrementally.

          (l) On each Settlement Date, the Company shall deliver the Shares
purchased by the Purchaser to the Purchaser or its designees via DWAC, against
payment therefor to the Company's designated account by wire transfer of
immediately available funds, provided that the Shares are received by the
Purchaser no later than 1:00 p.m. (New York time), or of next day available
funds if the Shares are received thereafter. In certain circumstances and as set
forth in

                                       23
<PAGE>

Section 9.1(b), a failure by the Company to deliver such Shares may result in
the payment of liquidated damages by the Company to the Purchaser.

          (m) If during a Draw Down Pricing Period the Company elects to reduce
the number of Trading Days in such Draw Down Pricing Period, the Company will
notify the Purchaser before commencement of trading on any Trading Day (a
"SECTION 6.1(m) NOTICE") and the last Trading Day of such Draw Down Pricing
Period shall be the Trading Day preceding the receipt of the Section 6.1(m)
Notice; provided, however, that if the Company delivers the Section 6.1(m)
Notice during trading hours on a Trading Day, then the last Trading Day of such
Draw Down Pricing Period shall be the Trading Day on which the Section 6.1(m)
Notice was received by the Purchaser.

     The Purchaser will purchase the Truncated Draw Down Allocation Amount for
each of the Trading Days prior to receipt of the Section 6.1(m) Notice, for an
aggregate purchase price determined in accordance with clauses (b) and (i) of
this Section 6.1.

     In addition, the Purchaser may, at its option, elect to purchase Shares in
an additional dollar amount equal to the product of the Draw Down Amount
Requested, first multiplied by (x) a fraction, the numerator of which equals one
(1) and the denominator of which equals eighteen (18) or such other number of
Trading Days in such Draw Down Pricing Period as the parties may have mutually
agreed upon with respect to such Draw Down Pricing Period (eighteen or such
other mutually agreed upon number being referred to herein as the "Trading Day
Number"), and next mutiplied by (y) that number that is equal to the Trading Day
Number minus the number of Trading Days in the reduced Draw Down Pricing Period.
The price per share for such additional dollar amount shall equal (i) the
aggregate total of Truncated Draw Down Allocation Amounts during the reduced
Draw Down Pricing Period divided by (ii) the number of Shares to be purchased
during such reduced Draw Down Pricing Period.

     Upon receipt of the Section 6.1(m) Notice, the Purchaser may (x) elect to
purchase the Common Stock at the Threshold Price for any Trading Day that the
VWAP was below the Threshold Price during the reduced Draw Down Pricing Period
in accordance with Section 6.1(i) hereof, (y) elect to purchase the Common Stock
in the additional amount as set forth in the preceding paragraph of this Section
6.1(m), and (z) elect to exercise any unexercised Call Options (for a Call
Option Amount not in excess of $1,000,000) by issuing a Call Option Notice to
the Company, in each such case, no later than 10:00 a.m. (New York time) on the
first Trading Day after the end of the reduced Draw Down Pricing Period. The
exercise price of the Call Option shall be based on the VWAP on the last Trading
Day of the reduced Draw Down Pricing Period (in lieu of the VWAP as specified in
clause (A) of Section 6.2(b) hereof) and otherwise determined in accordance with
Section 6.2(b) hereof.

     The Settlement Date for the Draw Down Amount and any Call Options exercised
during a reduced Draw Down Pricing Period shall be the second Trading Day after
receipt of the Section 6.1(m) Notice.

     Section 6.2 PURCHASER'S CALL OPTION. Subject to the satisfaction of the
conditions set forth in this Agreement, and subject to Section 6.3 below, the
parties agree as follows:

                                       24
<PAGE>

          (a) The Company may, in its sole discretion, grant to the Purchaser
the right to exercise one (1) or more Call Options during each Draw Down Pricing
Period for a specified Call Option Amount Requested; provided, however, that (i)
each Call Option Amount Requested shall be for a minimum of $50,000, (ii) the
aggregate total of all Call Option Amounts Requested during a Draw Down Pricing
Period may not exceed $8,000,000, or such other amount mutually agreed upon by
the Company and the Purchaser, and (iii) the Call Option Amount on any Trading
Day during the Draw Down Pricing Period may not exceed $1,000,000. The Call
Option Amount Requested and the Call Option Threshold Price shall be set forth
in the Draw Down Notice.

          (b) The number of shares of Common Stock to be issued in connection
with each Call Option shall equal (i) the Call Option Amount divided by (ii) the
applicable percentage set forth in this Section 6.2(b) multiplied by the greater
of (A) the VWAP for the Common Stock on the day the Purchaser issues its Call
Option Notice or (B) the Call Option Threshold Price. If the Market
Capitalization is equal to or above $1 billion, the Draw Down Discount Price
shall be 96.00% of the VWAP. If the Market Capitalization is below $1 billion
and equal to or above $750 million, the Draw Down Discount Price shall be 95.50%
of the VWAP. If the Market Capitalization is below $750 million and equal to or
above $500 million, the Draw Down Discount Price shall be 95.00% of the VWAP.
From $500 million to $300 million, for each $100 million decrease in Market
Capitalization, the Draw Down Discount Price shall be decreased by 0.50%
incrementally.

          (c) Each Call Option exercised shall be settled on the next Settlement
Date.

          (d) The Call Option Threshold Price designated by the Company in its
Draw Down Notice shall apply to each Call Option.

          (e) For each Call Option that the Purchaser exercises pursuant to this
Section 6.2, as a condition to such exercise the Purchaser must issue a Call
Option Notice (as defined in Section 1.1(h) hereof) to the Company no later than
8:00 p.m. (New York time) on the day such Call Option is exercised. If the
Purchaser does not exercise a Call Option by 8:00 p.m. (New York time) on the
last day of the applicable Draw Down Pricing Period, the Purchaser's Call
Options with respect to that Draw Down Pricing Period shall automatically
terminate.

     Section 6.3 AGGREGATE LIMIT. Notwithstanding anything to the contrary
herein, in no event may the Company issue a Draw Down Notice or grant a Call
Option to the extent that the sale of shares of Common Stock pursuant thereto
and pursuant to all prior Draw Down Notices or Call Options issued hereunder
would cause the Company to sell or the Purchaser to purchase shares of Common
Stock which in the aggregate are in a dollar amount in excess of the Aggregate
Limit. If the Company issues a Draw Down Notice or Call Option that otherwise
would permit the Purchaser to purchase shares of Common Stock which would cause
the aggregate purchases by Purchaser hereunder to exceed the Aggregate Limit,
such Draw Down Notice or Call Option shall be void AB INITIO to the extent of
the amount by which the value of shares of Common Stock otherwise issuable
pursuant to such Draw Down Notice or Call Option together with the value of all
other Common Stock purchased by the Purchaser pursuant hereto would exceed the
Aggregate Limit.

                                   TERMINATION

     Section 7.1 TERM; TERMINATION BY MUTUAL CONSENT. The term of this Agreement
shall expire on the earlier of (i) forty (40) consecutive months from the
Effective Date (the "INVESTMENT PERIOD"), (ii) the date that the entire dollar
amount of Shares registered under the Rule 429 Registration Statement have been
issued and sold and (iii) the date the Purchaser shall have purchased
$149,000,000 of Common Stock. The Company may terminate this Agreement effective
upon thirty (30) days' written notice; provided, however, that such termination
does not occur during a Draw Down Pricing Period or prior to a Settlement Date.
This Agreement may be terminated at any time by mutual written consent of the
parties.

     Section 7.2 OTHER TERMINATION. The Company shall inform the Purchaser, and
the Purchaser shall have the right to terminate this Agreement within the
subsequent thirty (30) days (the "EVENT PERIOD"), if during the Investment
Period (x) the Company enters into a definitive agreement with any third party,
the principal purpose of which is to secure any equity financing which provides
for (i) the issuance of the Common Stock or securities convertible into Common
Stock at a discount to the then current market price of the Common Stock, other
than an underwritten public offering or an Acceptable Financing (as defined in
Section 4.8(b) hereof), or (ii) the implementation by the Company of a mechanism
for the reset of the purchase price of the Common Stock to below the then
current market price of the Common Stock, or (y) an event resulting in a
Material Adverse Effect or a Material Change in Ownership has occurred. In such
event, the Purchaser may terminate this Agreement upon one (1) business day's
prior written notice during the Event Period.

     Section 7.3 EFFECT OF TERMINATION. In the event of termination by the
Company or the Purchaser, written notice thereof shall forthwith be given to the
other party and the transactions contemplated by this Agreement shall be
terminated without further action by either party. If this Agreement is
terminated as provided in Section 7.1 or 7.2 herein, this Agreement shall become
void and of no further force and effect, except as provided in Section 9.9
hereof. Nothing in this Section 7.3 shall be deemed to release the Company or
the Purchaser from any liability for any breach under this Agreement, or to
impair the rights of the Company and the Purchaser to compel specific
performance by the other party of its obligations under this Agreement.

                                 INDEMNIFICATION

     Section 8.1 GENERAL INDEMNITY.

          (a) INDEMNIFICATION BY THE COMPANY. The Company will indemnify and
hold harmless the Purchaser, Carlin and each person, if any, who controls the
Purchaser or Carlin within the meaning of Section 15 of the Securities Act or
Section 20(a) of the Exchange Act from and against any losses, claims, damages,
liabilities and expenses (including reasonable costs of defense and
investigation and all attorneys' fees) to which the Purchaser, Carlin and each
such

                                       26
<PAGE>

controlling person may become subject, under the Securities Act or otherwise,
insofar as such losses, claims, damages, liabilities and expenses (or actions in
respect thereof) arise out of or are based upon (i) any untrue statement or
alleged untrue statement of a material fact contained, or incorporated by
reference, in the Rule 429 Registration Statement relating to Common Stock being
sold to the Purchaser (including any Prospectus or Prospectus supplement which
are a part of it), or any amendment or supplement to it, or (ii) the omission or
alleged omission to state in the Rule 429 Registration Statement or any document
incorporated by reference in the Rule 429 Registration Statement, a material
fact required to be stated therein or necessary to make the statements therein
not misleading.

     The Company will reimburse the Purchaser, Carlin and each such controlling
person promptly upon demand for any legal or other costs or expenses reasonably
incurred by the Purchaser, Carlin or such controlling person in investigating,
defending against, or preparing to defend against any such claim, action, suit
or proceeding, except that the Company will not be liable to the extent any
loss, claim, damage, liability or expense arises out of, or is based upon, an
untrue statement, alleged untrue statement, omission or alleged omission,
included in any Prospectus or Prospectus supplement or any amendment or
supplement to the Prospectus or Prospectus supplement in reliance upon, and in
conformity with, written information furnished by either the Purchaser, Carlin
to the Company for inclusion in the Prospectus or Prospectus supplement.

          (b) INDEMNIFICATION BY THE PURCHASER. The Purchaser will indemnify and
hold harmless the Company, each of its directors and officers, and each person,
if any, who controls the Company within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act from and against any
expenses (including reasonable costs of defense and investigation and all
attorneys fees) to which the Purchaser and each such controlling person may
become subject, under the Securities Act or otherwise, insofar as such losses,
claims, damages, liabilities and expenses (or actions in respect thereof) arise

omission or alleged omission, included in any Prospectus or Prospectus
supplement or any amendment or supplement to the Prospectus or Prospectus
supplement in reliance upon, and in conformity with, written information
furnished by the Purchaser to the Company for inclusion in the Prospectus or
Prospectus supplement, or (ii) the omission or alleged omission to state in any
Prospectus or Prospectus supplement or any amendment or supplement to it a

therein not misleading, to the extent, but only to the extent, the untrue
statement, alleged untrue statement, omission or alleged omission was made in
reliance upon, and in conformity with, written information furnished by the
Purchaser to the Company for inclusion in the Prospectus or Prospectus
supplement or an amendment or supplement to it. The Purchaser will reimburse the
Company and each such director, officer or controlling person promptly upon
demand for any legal or other costs or expenses reasonably incurred by the
Company or the other person in investigating, defending against, or preparing to
defend against any loss, claim, damage, liability or expense arising out of, or
based upon, an untrue statement, alleged untrue statement, omission or alleged
omission, included in any Prospectus or Prospectus supplement or any amendment

     Section 8.2 INDEMNIFICATION PROCEDURES. Promptly after a person receives
notice of a claim or the commencement of an action for which the person intends
to seek indemnification under Section 8.1, the person will notify the
indemnifying party in writing of the claim or commencement of the action, suit
or proceeding; provided, however, that failure to notify the indemnifying party
will not relieve the indemnifying party from liability under Section 8.1, except
to the extent it has been materially prejudiced by the failure to give notice.
The indemnifying party will be entitled to participate in the defense of any
claim, action, suit or proceeding as to which indemnification is being sought,
and if the indemnifying party acknowledges in writing the obligation to
indemnify the party against whom the claim or action is brought, the
indemnifying party may (but will not be required to) assume the defense against
the claim, action, suit or proceeding with counsel satisfactory to it. After an
indemnifying party notifies an indemnified party that the indemnifying party
wishes to assume the defense of a claim, action, suit or proceeding, the
indemnifying party will not be liable for any legal or other expenses incurred
by the indemnified party in connection with the defense against the claim,
action, suit or proceeding except that if, in the opinion of counsel to the
indemnifying party, one or more of the indemnified parties should be separately
represented in connection with a claim, action, suit or proceeding, the
indemnifying party will pay the reasonable fees and expenses of one separate
counsel for the indemnified parties. Each indemnified party, as a condition to
receiving indemnification as provided in Section 8.1, will cooperate in all
reasonable respects with the indemnifying party in the defense of any action or
claim as to which indemnification is sought. No indemnifying party will be
liable for any settlement of any action effected without its prior written
consent. No indemnifying party will, without the prior written consent of the
indemnified party, effect any settlement of a pending or threatened action with
respect to which an indemnified party is, or is informed that it may be, made a
party and for which it would be entitled to indemnification, unless the
settlement includes an unconditional release of the indemnified party from all
liability and claims which are the subject matter of the pending or threatened
action.

     If for any reason the indemnification provided for in this Agreement is not
available to, or is not sufficient to hold harmless, an indemnified party in
respect of any loss or liability referred to in Section 8.1 as to which it is
entitled to indemnification thereunder, each indemnifying party will, in lieu of
indemnifying the indemnified party, contribute to the amount paid or payable by
the indemnified party as a result of such loss or liability, (i) in the
proportion which is appropriate to reflect the relative benefits received by the
indemnifying party on the one hand and by the indemnified party on the other
from the sale of Shares which is the subject of the claim, action, suit or
proceeding which resulted in the loss or liability or (ii) if that allocation is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits of the sale of such Shares, but also the relative
fault of the indemnifying party and the indemnified party with respect to the
statements or omissions which are the subject of the claim, action, suit or
proceeding that resulted in the loss or liability, as well as any other relevant
equitable considerations.

                                  MISCELLANEOUS

     Section 9.1 FEES AND EXPENSES.

          (a) Each party shall bear its own fees and expenses related to the
transactions contemplated by this Agreement; provided, however, that the Company
shall pay, at the Closing, all reasonable attorneys' fees and expenses
(exclusive of disbursements and out-of-pocket expenses) incurred by the
Purchaser up to $50,000 in connection with the preparation, negotiation,
execution and delivery of this Agreement. In addition, the Company shall pay all
reasonable attorneys' fees and expenses incurred by the Purchaser in connection
with any amendments, modifications or waivers of this Agreement. The Company
shall pay all stamp or other similar taxes and duties levied in connection with
issuance of the Shares pursuant hereto.

          (b) If the Company issues a Draw Down Notice and fails to deliver the
Shares on the applicable Settlement Date, and such failure continues for ten
(10) Trading Days, the Company shall pay the Purchaser, in cash or restricted
shares of Common Stock, at the option of the Purchaser, as liquidated damages
for such failure and not as a penalty an amount equal to two percent (2%) of the
payment required to be paid by the Purchaser on such Settlement Date (i.e., the
sum of the Draw Down Amount and the Call Option Amount) for the initial thirty
(30) days following such Settlement Date until the Shares have been delivered,
and an additional two percent (2%) for each additional thirty (30) day period
thereafter until the Shares have been delivered, which amount shall be prorated
for such periods less than thirty (30) days.

     Section 9.2 SPECIFIC ENFORCEMENT, CONSENT TO JURISDICTION.

          (a) The Company and the Purchaser acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that either party shall be entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Agreement by the other party and to enforce specifically the terms and
provisions hereof, this being in addition to any other remedy to which either
party may be entitled by law or equity.

          (b) Each of the Company and the Purchaser (i) hereby irrevocably
submits to the jurisdiction of the United States District Court and other courts
of the United States sitting in the State of New York for the purposes of any
suit, action or proceeding arising out of or relating to this Agreement, and
(ii) hereby waives, and agrees not to assert in any such suit, action or
proceeding, any claim that it is not personally subject to the jurisdiction of
such court, that the suit, action or proceeding is brought in an inconvenient
forum or that the venue of the suit, action or proceeding is improper. Each of
the Company and the Purchaser consents to process being served in any such suit,
action or proceeding by mailing a copy thereof to such party at the address in
effect for notices to it under this Agreement and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing in
this Section shall affect or limit any right to serve process in any other
manner permitted by law.

                  merged with or into the Parent Guarantor or any Restricted

                  (a) GENERAL. The Notes and the Trustee's certificate of
authentication shall be substantially in the form of Exhibit A hereto. The Notes
may have notations, legends or endorsements required by law, stock exchange rule
or usage. Each Note shall be dated the date of its authentication. The Notes
shall be in denominations of $1,000 and integral multiples thereof. The terms
and provisions contained in the Notes shall constitute, and are hereby expressly
made, a part of this Indenture and, to the extent applicable, the Company, the
Guarantors and the Trustee, by their execution and delivery of this Indenture,
expressly agree to such terms and provisions and to be bound thereby.

                                      34

<PAGE>

However, to the extent any provision of any Note conflicts with the express
provisions of this Indenture, the provisions of this Indenture shall govern and
be controlling.

                  (b) FORM OF NOTES. Notes issued in global form shall be
substantially in the form of Exhibit A attached hereto (including the Global
Note Legend thereon and the "Schedule of Exchanges of Interests in the Global
Note" attached thereto). Notes issued in definitive form shall be substantially
in the form of EXHIBIT A attached hereto (but without the Global Note Legend
thereon and without the "Schedule of Exchanges of Interests in the Global Note"
attached thereto). Each Global Note shall represent such of the outstanding
Notes as shall be specified therein and each shall provide that it shall
represent the aggregate principal amount of outstanding Notes from time to time
endorsed thereon and that the aggregate principal amount of outstanding Notes
represented thereby may from time to time be reduced or increased, as
appropriate, to reflect exchanges and redemptions. Any endorsement of a Global
Note to reflect the amount of any increase or decrease in the aggregate
principal amount of outstanding Notes represented thereby shall be made by the
Trustee or the Custodian, at the direction of the Trustee, in accordance with
instructions given by the Holder thereof as required by Section 2.06 hereof.

                  (c) EUROCLEAR AND CLEARSTREAM PROCEDURES APPLICABLE. The
provisions of the "Operating Procedures of the Euroclear System" and "Terms and
Conditions Governing Use of Euroclear" and the equivalent procedures of
Clearstream shall be applicable to transfers of beneficial interests in Global
Notes that are held by Participants through Euroclear or Clearstream.

                  (d) Subject to compliance with the provisions of Section 4.09
of this Indenture, the Company may issue Additional Notes under this Indenture.

SECTION 2.02.         EXECUTION AND AUTHENTICATION.

                  (a) One Officer shall sign the Notes for the Company by manual
or facsimile signature. The Company's seal may be reproduced on the Notes and
may be in facsimile form.

                  (b) If an Officer whose signature is on a Note no longer holds
that office at the time a Note is authenticated, the Note shall nevertheless be
valid.

                  (c) A Note shall not be valid until authenticated by the
manual signature of a Responsible Officer of the Trustee. The signature of a
Responsible Officer of the Trustee on the certificate of authentication on a
Note shall be conclusive evidence that the Note has been authenticated under
this Indenture.

                  (d) The Trustee shall, upon a written order of the Company
signed by an Officer (an "AUTHENTICATION ORDER"), authenticate Notes for
original issue up to the aggregate principal amount stated in Section 2.01(d).

<PAGE>

Notes outstanding at any time may not exceed such amount except as provided in
Section 2.07 hereof.

                  (e) The Trustee may appoint an authenticating agent acceptable
to the Company to authenticate Notes. An authenticating agent may authenticate
Notes 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 an Agent to deal with Holders or an
Affiliate of the Company.

SECTION 2.03.         REGISTRAR AND PAYING AGENT.

                  (a) The Company shall maintain an office or agency where Notes
may be presented for registration of transfer or for exchange ("REGISTRAR") and
an office or agency where Notes may be presented for payment ("PAYING AGENT").
The Registrar shall keep a register of the Notes and of their transfer and
exchange. The Company may appoint one or more co-registrars and one or more
additional Paying Agents. The term "Registrar" includes any co-registrar and the
term "Paying Agent" includes any additional paying agent. The Company may change
any Paying Agent or Registrar without notice to any Holder. The Company shall
notify the Trustee in writing of the name and address of any Agent not a party
to this Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar.

                  (b) The Company initially appoints The Depository Trust
Company ("DTC") to act as Depositary with respect to the Global Notes. Whenever
this Indenture, the Escrow Agreement or any other document related hereto or
thereto requires or permits actions to be taken based on instructions or
directions of Holders of Notes evidencing a specified percentage of the
aggregate principal amount of the Notes then outstanding, the Depositary will be
deemed to represent such percentage only to the extent that it has received
instructions or directions to that effect from the Holders of the Notes and/or
Indirect Participants or Participants owning or representing, respectively, such
required percentage of the beneficial interest in the Notes, as shall be
conclusively evidenced by the Depositary's delivery of such instructions or
directions to the Trustee.

                  (c) The Company initially appoints the Trustee to act as the
Registrar and Paying Agent and to act as Custodian with respect to the Global
Notes.

                  (d) The Global Notes shall be initially registered in the name
of Cede & Co., nominee of DTC.

SECTION 2.04.         PAYING AGENT TO HOLD MONEY IN TRUST.

                  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 Holders or the Trustee all money held by the Paying Agent for the
payment of principal of, and premium, Liquidated Damages, if any, or interest
on, the Notes, and shall notify the

                                      36

<PAGE>

Trustee of any default by the Company in making any such payment. While any
such default continues, the Trustee may require a Paying Agent to pay all money
held by it to the Trustee. The Company at any time may require a Paying Agent
to pay all money held by it to the Trustee. Upon payment over to the Trustee,
the Paying Agent (if other than the Company or a Subsidiary of the Company)
shall have no further liability for the money. If the Company or one of its
Subsidiaries acts as Paying Agent, it shall segregate and hold in a separate
trust fund for the benefit of the Holders all money held by it as Paying Agent.
Upon any bankruptcy or reorganization proceedings relating to the Company, the
Trustee shall serve as Paying Agent for the Notes.

SECTION 2.05.         HOLDER 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 all Holders and shall otherwise comply with TIA Section 312(a). If
the Trustee is not the Registrar, the Company shall furnish to the Trustee at
least seven Business Days or such shorter time as the Trustee may allow 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 the Holders of Notes, including the
aggregate principal amount of Notes held by each Holder.

SECTION 2.06.         TRANSFER AND EXCHANGE.

                  (a) TRANSFER AND EXCHANGE OF GLOBAL NOTES. A Global Note may
not be transferred as a whole except by the Depositary to a nominee of the
Depositary, by a nominee of the Depositary to the Depositary or to another
nominee of the Depositary, or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary. Global Notes
will be exchanged by the Company for Definitive Notes if (i) the Depositary (x)
notifies the Company that it is unwilling or unable to continue to act as
depositary for the Global Notes and the Company thereupon fails to appoint a
successor Depositary, or (y) has ceased to be a clearing agency registered under
the Exchange Act and the Company fails to appoint a successor, and, in either
case, a successor Depositary is not appointed by the Company within 90 days
after the date of such notice from the Depositary or (ii) the Company in its
sole discretion determines that the Global Notes should be exchanged for
Definitive Notes and delivers a written notice to such effect to the Trustee;
PROVIDED, HOWEVER, that in no event shall the Regulation S Temporary Global Note
be exchanged by the Company for Definitive Notes prior to (A) the expiration of
the Restricted Period and (B) the receipt by the Registrar of any certificates
required pursuant to Regulation S as determined by the Company. Upon the
occurrence of any of the preceding events in (i) or (ii) above, Definitive Notes
shall be issued in such names as the Depositary shall instruct the Trustee.
Global Notes also may be exchanged or replaced, in whole or in part, as provided
in Sections 2.07 and 2.10 hereof. Every Note authenticated and delivered in
exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to
this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and
delivered in the form of, and shall be, a Global Note. A Global

                                      37

<PAGE>

Note may not be exchanged for another Note other than as provided in Sections
2.06(a), 2.07, 2.10 and 9.05 hereof, although beneficial interests in a Global
Note may be transferred and exchanged as provided in Section 2.06(b), (c), (d)
or (f) hereof.

                  (b) TRANSFER AND EXCHANGE OF BENEFICIAL INTERESTS IN THE
GLOBAL NOTES. The transfer and exchange of beneficial interests in the Global
Notes shall be effected through the Depositary, in accordance with the
provisions of this Indenture and the Applicable Procedures. Beneficial interests
in the Restricted Global Notes shall be subject to restrictions on transfer
comparable to those set forth herein to the extent required by the Securities
Act. Transfers of beneficial interests in the Global Notes also shall require

         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in the same Restricted Global Note in accordance
         with the transfer restrictions set forth in the Private Placement
         Legend; PROVIDED, HOWEVER, that prior to the expiration of the
         Restricted Period, transfers of beneficial interests in the Regulation
         S Global Note may not be made to a U.S. Person or for the account or
         benefit of a U.S. Person (other than the Initial Purchasers).
         Beneficial interests in any Unrestricted Global Note may be
         transferred to Persons who take delivery thereof in the form of a
         beneficial interest in an Unrestricted Global Note. No written orders
         or instructions shall be required to be delivered to the Registrar to
         effect the transfers described in this Section 2.06(b)(i).

                  (ii)  ALL OTHER TRANSFERS AND EXCHANGES OF BENEFICIAL
         INTERESTS IN GLOBAL NOTES. In connection with all transfers and
         exchanges of beneficial interests that are not subject to Section
         2.06(b)(i) above, the transferor of such beneficial interest must
         deliver to the Registrar either (A) (1) a written order from a
         Participant or an Indirect Participant given to the Depositary in
         accordance with the Applicable Procedures directing the Depositary to
         credit or cause to be credited a beneficial interest in another Global
         Note in an amount equal to the beneficial interest to be transferred
         or exchanged and (2) instructions given in accordance with the
         Applicable Procedures containing information regarding the Participant
         account to be credited with such increase or (B), subject to Section

         or exchanged and (2) instructions given by the Depositary to the
         Registrar containing information regarding the Person in whose name
         such Definitive Note shall be registered to effect the transfer or
         exchange referred to in (1) above; PROVIDED, HOWEVER, that in no event
         shall Definitive Notes be issued upon the transfer or exchange of
         beneficial interests in the Regulation S Temporary Global Note prior
         to (x) the expiration of the Restricted Period and

                                      38

<PAGE>

         (y) the receipt by the Registrar of any certificates required pursuant
         to Regulation S, as determined by the Company. Upon consummation of an
         Exchange Offer by the Company in accordance with Section 2.06(f)
         hereof, the requirements of this Section 2.06(b)(ii) shall be deemed
         to have been satisfied upon receipt by the Registrar of the
         instructions contained in the Letter of Transmittal or in a comparable
         communication in accordance with the Applicable Procedures delivered
         by the Holder of such beneficial interests in the Restricted Global
         Notes. Upon satisfaction of all of the requirements for transfer or
         exchange of beneficial interests in Global Notes contained in this
         Indenture and the Notes or otherwise applicable under the Securities
         Act, the Trustee shall adjust the principal amount of the relevant
         Global Note(s) pursuant to Section 2.06(h) hereof.

                  (iii) TRANSFER OF BENEFICIAL INTERESTS TO ANOTHER RESTRICTED
         GLOBAL NOTE. A beneficial interest in any Restricted Global Note may be
         transferred to a Person who takes delivery thereof in the form of a
         beneficial interest in another Restricted Global Note if the transfer
         complies with the requirements of Section 2.06(b)(ii) above and the

         RESTRICTED DEFINITIVE NOTES. Restricted Global Notes and beneficial
         interests therein shall be exchangeable for Definitive Notes if (i) the
         Depositary (x) notifies the Company that it is unwilling or unable to
         continue to act as depositary for the Restricted Global Notes and the
         Company thereupon fails to appoint a successor Depositary, or (y) has

         successor Depositary is not appointed by the Company within 90 days
         after the date of such notice from the Depositary, or (ii) the Company,
         at its option, notifies the Trustee in writing that it elects to cause
         the issuance of the Definitive Notes. In all cases, Definitive Notes

         interests therein shall be registered in the names, and issued in any
         approved denominations, requested by or on behalf of the Depositary (in

                        In such event, the Trustee shall cause the Restricted

         Participant. Any Definitive Note issued in exchange for a beneficial
         interest in a Restricted Global Note pursuant to this Section
         2.06(c)(i) shall bear the Private Placement Legend and shall be subject
         to all restrictions on transfer contained therein.

                        In the event of a transfer or exchange of beneficial
         interests in Global Notes for Definitive Notes, the Trustee and
         Registrar shall be entitled to rely on directions from Indirect
         Participants, Participants or the Depositary as to the name of the
         Holders in which to register the Definitive Notes and as to delivery
         instructions; none of the Company, the Trustee or the Registrar shall
         be liable for any delay in receipt of or failure to receive such
         directions and each may conclusively rely on, and shall be protected in
         relying on, such instructions.

         Restricted Global Note may exchange such beneficial interest for an

SECTION 2.07.         REPLACEMENT NOTES.

                  (a) If any mutilated Note is surrendered to the Trustee or the
Company and the Trustee receives evidence to its satisfaction of the
destruction, loss or theft of any Note, the Company shall issue and the Trustee,
upon receipt of an Authentication Order in accordance with Section 2.02 with
respect to such Note, shall authenticate a replacement Note if the Trustee's
requirements are met. If required by the Trustee or the Company, an indemnity
bond must be supplied by the Holder that is sufficient in the judgment of the
Trustee and the Company to protect the Company, the Trustee, any Agent and any
authenticating agent from any loss that any of them may suffer if a Note is
replaced. The Company may charge for its expenses in replacing a Note.

                  (b) Every replacement Note is an additional obligation of the
Company and shall be entitled to all of the benefits of this Indenture equally
and proportionately with all other Notes duly issued hereunder.

SECTION 2.08.         OUTSTANDING NOTES.

                  (a) The Notes outstanding at any time are all the Notes
authenticated by the Trustee except for those cancelled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Note
effected by the Trustee in accordance with the provisions hereof, and those
described in this Section 2.08 as not outstanding. Except as set forth in
Section 2.09 hereof, a Note does not cease to be outstanding because the Company
or an Affiliate of the Company holds the Note; however, Notes held by the
Company or a Subsidiary of the Company shall not be deemed to be outstanding for
purposes of Section 3.07(b) hereof.

                  (b) If a Note is replaced pursuant to Section 2.07 hereof, it
ceases to be outstanding and interest on the Notes ceases to accrue unless the
Trustee receives proof satisfactory to it that the replaced Note is held by a
bona fide purchaser.

                  (c) If the principal amount of any Note is considered paid
under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases
to accrue.

                  (d) If the Paying Agent (other than the Company, a Subsidiary
or an Affiliate of any thereof) holds, on a redemption date or maturity date,
money for the purposes of and sufficient to pay Notes payable on that date, then
on and after that date such Notes shall be deemed to be no longer outstanding
and shall cease to accrue interest.

SECTION 2.09.         TREASURY NOTES.

                  In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes owned
by the Company,

                                      53

<PAGE>

or by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company, shall be considered as
though not outstanding, except that for the purposes of determining whether
the Trustee shall be protected in relying on any such direction, waiver or
consent, only Notes that the Trustee knows are so owned shall be so
disregarded.

SECTION 2.10.         TEMPORARY NOTES.

                  Until certificates representing Notes are ready for delivery,
the Company may prepare and the Trustee, upon receipt of an Authentication Order
in accordance with Section 2.02 with respect to such Notes, shall authenticate
temporary Notes. Temporary Notes shall be substantially in the form of
Definitive Notes but may have variations that the Company considers appropriate
for temporary Notes and as shall be reasonably acceptable to the Trustee.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate Definitive Notes in exchange for temporary Notes. After the
preparation of Definitive Notes, the temporary Notes shall be exchangeable for
definitive Notes upon surrender of the temporary Notes at the office or agency
of the Company designated for such purpose pursuant to Section 4.02 without
charge to the Holder. Upon surrender for cancellation of any one or more
temporary Notes, the Company shall execute and, upon receipt of an
Authentication Order in accordance with Section 2.02 with respect to such Notes,
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of Definitive Notes of authorized denominations.

                  Holders of temporary Notes shall be entitled to all of the
benefits of this Indenture.

SECTION 2.11.         CANCELLATION.

                  The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee upon direction by the Company and no one else shall cancel all Notes
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall destroy cancelled Notes (subject to the record retention
requirements of the Exchange Act). Certification of the destruction of all
cancelled Notes shall be delivered to the Company. The Company may not issue new
Notes to replace Notes that it has paid or that have been delivered to the
Trustee for cancellation.

SECTION 2.12.         DEFAULTED INTEREST.

                  If the Company defaults in a payment of interest on the Notes,
it shall pay the defaulted interest in any lawful manner plus, to the extent
lawful, interest payable on the defaulted interest, to the Persons who are
Holders on a subsequent special record date, in each case at the rate provided
in the Notes and in Section 4.01 hereof. The Company shall notify the Trustee in
writing of the amount of defaulted interest proposed to be paid

                                      54

<PAGE>

on each Note and the date of the proposed payment. The Company shall fix or
cause to be fixed each such special record date and payment date; PROVIDED,
HOWEVER, that no such special record date shall be less than 5 days prior to
the related payment date for such defaulted interest. At least 10 days before
the special record date, the Company (or, upon the written request of the
Company, the Trustee in the name and at the expense of the Company) shall
mail or cause to be mailed to Holders a notice that states the special record
date, the related payment date and the amount of such interest to be paid.

SECTION 2.13.         CUSIP AND ISIN NUMBERS.

                  The Company in issuing the Notes may use "CUSIP" and "ISIN"
numbers (if then generally in use), and, if so, the Trustee shall use "CUSIP"
and "ISIN" 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 Notes or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Notes, and any such redemption
shall not be affected by any defect in or omission of such numbers. The Company
will promptly notify the Trustee of any change in the "CUSIP" and "ISIN"
numbers.

redemption provisions of Section 3.07 hereof, it shall furnish to the Trustee,

in an Offer to Purchase at any time, the Trustee shall select the Notes to be
redeemed or purchased among the Holders of the Notes in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not so listed, on a PRO RATA basis, by lot
or in accordance with any other method the Trustee considers fair and
appropriate or in accordance with the Applicable Procedures. In the event of
partial redemption by lot, the particular Notes to be redeemed shall be
selected, unless otherwise provided herein, not less than 30 nor more than 60
days prior to the redemption date by the Trustee from the outstanding Notes not
previously called for redemption.

                                      55

<PAGE>

                  The Trustee shall promptly notify the Company in writing of
the Notes selected for redemption and, in the case of any Note selected for
partial redemption, the principal amount thereof to be redeemed. Notes and
portions of Notes selected shall be in amounts of $1,000 or whole multiples of
$1,000; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder, even if not a multiple
of $1,000, shall be redeemed. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption also
apply to portions of Notes called for redemption.

SECTION 3.03.         NOTICE OF REDEMPTION.

                  Subject to the provisions of Section 3.07 hereof, at least 30

or cause to be mailed, by first class mail, a notice of redemption to each
Holder whose Notes are to be redeemed at its registered address.

state:

                  (a) the redemption date;

                  (b) the redemption price;

                  (c) if any Note is being redeemed in part, the portion of the
principal amount of such Note to be redeemed and that, after the redemption date
upon surrender of such Note, a new Note or Notes in principal amount equal to
the unredeemed portion shall be issued upon cancellation of the original Note;

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

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

                  (f) that, unless the Company defaults in making such
redemption payment, interest and Liquidated Damages, if any, on Notes called for
redemption ceases to accrue on and after the redemption date;

                  (g) the paragraph of the Notes or Section of this Indenture
pursuant to which the Notes called for redemption are being redeemed; and

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

                  At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the
Company shall have delivered to the Trustee at least 45 days (unless a shorter
period shall be agreed to by the Trustee in writing) but not more than 60 days
prior to the redemption date, an

                                      56

<PAGE>

Officers' Certificate in accordance with Sections 13.04 and 13.05 requesting
that the Trustee give such notice and setting forth the information to be
stated in such notice as provided in the preceding paragraph.

SECTION 3.04.         EFFECT OF NOTICE OF REDEMPTION.

                  Once notice of redemption is mailed in accordance with Section
3.03 hereof, Notes called for redemption shall become irrevocably due and
payable on the redemption date at the redemption price. A notice of redemption
may not be conditional.

                  A notice of redemption shall be deemed to be given when
mailed, whether or not the Holder receives the notice. In any event, failure to
give such notice, or any defect in such notice, shall not affect the validity of
the proceedings for the redemption of the Notes held by Holders to whom such
notice was properly given.

SECTION 3.05.         DEPOSIT OF REDEMPTION PRICE.

                  On or one Business Day prior to the redemption date, the
Company shall deposit with the Trustee or with the Paying Agent money sufficient
to pay the redemption price of and accrued interest and Liquidated Damages, if
any, on all Notes to be redeemed on that date. The Trustee or the Paying Agent
shall promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest on, all Notes to be redeemed.

                  If the Company complies with the provisions of the preceding
paragraph, on and after the redemption date, interest shall cease to accrue on
the Notes or the portions of Notes called for redemption. If a Note is redeemed
on or after an interest record date but on or prior to the related interest
payment date, then any accrued and unpaid interest shall be paid to the Person
in whose name such Note was registered at the close of business on such record
date. If any Note called for redemption shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall be paid on the unpaid principal from the redemption
date until such principal is paid, and to the extent lawful on any interest not
paid on such unpaid principal, in each case at the rate provided in the Notes
and in Section 4.01 hereof.

SECTION 3.06.         NOTES REDEEMED IN PART.

                  Upon surrender of a Note that is redeemed in part, the Company
shall issue and, upon receipt of an Authentication Order in accordance with
Section 2.02 with respect to such Notes, the Trustee shall authenticate for the
Holder at the expense of the Company a new Note equal in principal amount to the
unredeemed portion of the Note surrendered.

                           (A) a Default or Event of Default occurs and

PROVIDED, HOWEVER, that, except in the case of clauses (i) and (ii), no Default

         of such agreements; on the condition that, the encumbrances and
         restrictions in any such amendments, extensions, refinancings, renewals
         or replacements are no less favorable in all material respects to the
         Holders than those encumbrances or restrictions that are then in effect
         and that are being extended, refinanced, renewed or replaced;

                  (ii) existing under or by reason of applicable law;

         are not applicable to any Person or the property or assets of any
         Person other than such Person or the property or assets of such Person
         so acquired;

                  (iv) in the case of restrictions relating to the transfers of

                  property or assets of the Parent Guarantor or any Restricted
                  Subsidiary not otherwise prohibited by this Indenture or

                           (C) arise or agreed to in the ordinary course of
                  business, not relating to any Indebtedness, and that do not,
                  individually or in the aggregate, detract from the value of
                  property or assets of the Parent Guarantor or any Restricted
                  Subsidiary in any manner material to the Parent Guarantor or

                  (vi) contained in the terms of any Indebtedness (other than
         as contemplated by clause (i) above), or any agreement creating
         Indebtedness, of a Restricted Subsidiary entered into after the Issue
         Date if:

                           (A) the encumbrance or restriction applies only if
                  there is a payment default, a default with respect to a
                  financial covenant, or an event of default resulting in the
                  acceleration of the final maturity of such Indebtedness,

                           (B) the encumbrance or restriction is not materially
                  more disadvantageous to Holders of Notes than is customary in
                  comparable financings (as determined by the Company), and

                           (C) the Company determines that the encumbrance or
                  restriction shall not materially affect the ability to pay
                  interest on the Notes at their Stated Maturity or principal
                  and accrued and unpaid interest on the Notes at their final
                  Stated Maturity.

                  (c) The Parent Guarantor and its Restricted Subsidiaries are
not precluded from:

                  (i) creating, Incurring, assuming or permitting to exist any
         Liens otherwise permitted under Section 4.13, or

                  (ii)restricting the sale of their assets that secure
         Indebtedness of the Parent Guarantor or its Restricted Subsidiaries.

Restricted Subsidiary may Incur Indebtedness, if, after giving effect to the
Incurrence of such Indebtedness and the receipt and application of the proceeds
therefrom, the Consolidated Leverage Ratio would be less than 8.5 to 1 for
Indebtedness Incurred on or prior to September 30, 2002, 8.0 to 1 for

         thereof in an amount not to exceed the amount so refinanced or refunded
         (plus premiums, accrued interest, accrued dividends, fees and
         expenses), but only if such new Indebtedness, determined as of the date
         of Incurrence of such new Indebtedness, does not mature or have a
         mandatory redemption or repurchase date prior to the final Stated
         Maturity of the Indebtedness to be refinanced or refunded, and the
         Average Life of such new Indebtedness is at least equal to the

                           (1) Net Cash Proceeds received by the Company after
                  the Issue Date from the issuance and sale of (A) its Common
                  Stock or Preferred Shares convertible or exchangeable solely
                  into shares of such Common Stock (in either case, other than

                  or Preferred Shares convertible or exchangeable solely into
                  shares of such Common Stock (in either case, other than
                  Disqualified Stock) or (C) the sale of any Capital Stock
                  (other than Disqualified Stock) of the Company or the Parent

                  (B) or (C) being "Qualifying Capital Stock"), to the extent
                  such Net Cash Proceeds are contributed to the Company, to a
                  Person that is not a Restricted Subsidiary of the Parent
                  Guarantor to the extent such Net Cash Proceeds have not been
                  used pursuant to clause (4)(c)(ii) of Section 4.07(a), or
                  clause (7) of Section 4.07(b); and

                  Qualifying Capital Stock to a Person that is not a Restricted

                           (1) Net Cash Proceeds received by the Company after
                  the Issue Date from the issuance and sale of either any of its
                  Capital Stock (other than Qualifying Capital Stock and
                  Disqualified Stock), or the Parent Guarantor's Capital Stock
                  (other than Qualifying Capital Stock and Disqualified Stock)
                  to the extent such Net Cash Proceeds are contributed to the
                  Company, to a Person that is not a Restricted Subsidiary of
                  the Parent Guarantor to the extent such Net Cash Proceeds have
                  not been used pursuant to clause (4)(c)(ii) of Section
                  4.07(a), or clause (7) of Section 4.07(b); and

                           (2) 80% of the Fair Market Value of property other
                  than cash received by the Parent Guarantor or the Company
                  after the Issue Date from the issuance and sale of its Capital
                  Stock (other than Qualifying Capital Stock and Disqualified
                  Stock) to a Person that is not a Restricted Subsidiary of the
                  Parent Guarantor;

                  (vii) intercompany Indebtedness (other than any Guarantee to
         the extent addressed in clause (v) above) by or among the Parent
         Guarantor and its Restricted Subsidiaries; PROVIDED, HOWEVER, that (A)
         if the Company or the Parent Guarantor is the obligor on such
         Indebtedness, such Indebtedness is expressly subordinated to the prior
         payment in full in cash of all obligations in respect of the Notes or
         the Parent Guarantor's Guarantee of the Notes, as the case may be, and
         (B)(1) any subsequent issuance or transfer of Capital Stock that
         results in any such Indebtedness being held by a Person other than the
         Company or another Restricted Subsidiary of the Parent Guarantor and
         (2) any sale or other transfer of any such Indebtedness to a Person
         other than the Parent Guarantor, the Company or another Restricted
         Subsidiary of the Parent Guarantor shall be deemed, in each case, to
         constitute an Incurrence of Indebtedness by the Parent Guarantor, the
         Company or such Restricted Subsidiary, as the case may be, that was not
         permitted by this clause (vii); and

                  (viii) Indebtedness outstanding at any time in an aggregate
         principal amount not to exceed $100.0 million.

                  (c) The maximum amount of Indebtedness that the Parent
Guarantor or a Restricted Subsidiary may Incur pursuant to this Section 4.09
shall not be deemed to be exceeded, with respect to any outstanding
Indebtedness, due solely to the result of fluctuations in the exchange rates of
currencies.

                  (d) For purposes of determining any particular amount of
Indebtedness under this Section 4.09, Guarantees, Liens or obligations with
respect to letters of credit supporting Indebtedness otherwise included in the
determination of such particular amount shall not be included.

                  (e) For purposes of determining compliance with this Section
4.09, in the event that an item of proposed Indebtedness meets the criteria of
more than one of the categories of Indebtedness described in Section 4.09(b) or
would be entitled to be Incurred pursuant to Section 4.09(a), as of the date of
Incurrence thereof, the Company shall, in its sole discretion, classify (or
later classify or reclassify in whole or part, in its sole discretion), such
item of Indebtedness in any manner that complies with this Section 4.09.
Indebtedness under the Senior Credit Facility outstanding on the Issue Date
shall be deemed to have been Incurred on such date in reliance on the exception
set forth in clause (i) of Section 4.09(b) above. Accrual of interest, the
accretion of accreted value and the payment of interest in the form of
additional Indebtedness or the payment of dividends on Preferred Shares in the
form of additional shares of the same class or series of Preferred Shares shall
not be deemed an Incurrence of Indebtedness for purposes of this Section 4.09.

SECTION 4.10.         FUTURE SUBSIDIARY GUARANTORS.

                  The Parent Guarantor shall cause (1) each Domestic Restricted
Subsidiary that Incurs Indebtedness and (2) each Foreign Restricted Subsidiary
that Incurs Material Indebtedness to become a Subsidiary Guarantor, and, if
applicable, execute and deliver to the Trustee a supplemental indenture pursuant
to which that Restricted Subsidiary will guarantee payment of the Notes;
PROVIDED, HOWEVER, that in the event that a Subsidiary Guarantor no longer has
outstanding any Indebtedness, other than its Guarantee of the Notes (in the case
of a Domestic Restricted Subsidiary) or Material Indebtedness, other than its
Guarantee of the Notes (in the case of a Foreign Restricted Subsidiary), the
Subsidiary Guaranty of that Subsidiary Guarantor shall terminate. Each
Subsidiary Guaranty shall be limited to an amount not to exceed the maximum
amount that can be guaranteed by that Restricted Subsidiary without rendering
the Subsidiary Guaranty, as it relates to that Restricted Subsidiary, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

SECTION 4.11.         ASSET SALES.

                  (a) The Parent Guarantor shall not be permitted to, and shall
not permit any Restricted Subsidiaries to, consummate an Asset Sale unless:

                  (i) the Parent Guarantor or its Restricted Subsidiary, as the
         case may be, receives consideration at the time of the Asset Sale at
         least equal to the Fair Market Value, evidenced by a resolution of the
         Board of Directors set forth in an Officers' Certificate in accordance
         with Sections 13.04 and 13.05 delivered to the Trustee, of the assets
         or Equity Interests issued or sold or otherwise disposed of; and

                  (ii)at least 75% of the consideration therefor received by the
         Parent Guarantor or its Restricted Subsidiary consists of:

                                       72

<PAGE>

                           (A) cash or Cash Equivalents;

                           (B) the assumption of Indebtedness (other than
                  non-recourse Indebtedness or any Subordinated Indebtedness) of
                  the Parent Guarantor or such Restricted Subsidiary or other
                  obligations relating to such assets (accompanied by an
                  irrevocable and unconditional release of the Parent Guarantor
                  or such Restricted Subsidiary from all liability on the
                  Indebtedness or other obligations assumed); or

                           (C) notes, other obligations or common stock received
                  by the Parent Guarantor or such Restricted Subsidiary from
                  such transferee that are converted by the Parent Guarantor or
                  such Restricted Subsidiary into cash or Cash Equivalents
                  concurrently with the receipt of such notes or other
                  obligations (to the extent of the cash actually received by
                  the Parent Guarantor or its Restricted Subsidiary).

                  (b) In the event and to the extent that the Net Cash Proceeds
received by the Parent Guarantor or any Restricted Subsidiaries from one or more
Asset Sales occurring on or after the Issue Date in any period of twelve
consecutive months exceeds 10% of Adjusted Consolidated Net Tangible Assets
(determined as of the date closest to the commencement of such 12-month period
for which a consolidated balance sheet of the Company has been filed with the
Commission) then the Parent Guarantor shall or shall cause the relevant
Restricted Subsidiary, to:

                  (i) within twelve months after the date Net Cash Proceeds so
         received exceed 10% of Adjusted Consolidated Net Tangible Assets, to

                           (A) apply an amount equal to such excess Net Cash
                  Proceeds to permanently repay Senior Indebtedness of the
                  Company or Senior Indebtedness of any Restricted Subsidiary in
                  each case owing to a Person other than the Parent Guarantor or
                  any Restricted Subsidiaries, or

                           (B) invest an equal amount, or the amount not so
                  applied pursuant to clause (A) (or enter into a definitive
                  agreement committing to so invest within 12 months after the
                  date of such agreement), in property or assets (other than
                  current assets) of a nature or type or that are used in a
                  business (or in a company having property and assets of a
                  nature or type, or engaged in a business) related, ancillary
                  or complementary to the business of, the Company and its

                                       73

<PAGE>

                  Restricted Subsidiaries existing on the date of such
                  Investment, and

                  (ii) apply, no later than the end of the 12-month period
         referred to in clause (i) of this Section 4.11, such excess Net Cash
         Proceeds (to the extent not applied pursuant to clause (i)), as
         provided in Section 4.11(c). The amount of such excess Net Cash
         Proceeds required to be applied, or to be committed to be applied,
         during such twelve-month period as set forth in clause (i) of the
         preceding sentence and not applied as so required by the end of such
         period shall constitute "EXCESS PROCEEDS."

                  (c) If, as of the first day of any calendar month, the
aggregate amount of Excess Proceeds not theretofore subject to an Offer to
Purchase pursuant to this Section 4.11 totals at least $10.0 million, the
Company must commence, not later than the fifteenth Business Day of such month,
and consummate an Offer to Purchase from the Holders of Notes and the Holders of
any Indebtedness ranking equally with the Notes and entitled to participate in
such an Offer to Purchase on a pro rata basis, an aggregate principal amount of
Notes and such other Indebtedness equal to the Excess Proceeds on such date, at
a purchase price equal to 101% of the principal amount thereof, plus, in each
case, accrued interest and Liquidated Damages, if any, to the Payment Date.

SECTION 4.12.         TRANSACTIONS WITH AFFILIATES.

                  (a) The Parent Guarantor shall not, and shall not permit any
Restricted Subsidiaries to, directly or indirectly, engage in any transaction
including, without limitation, the purchase, sale, lease or exchange of property
or assets, or the rendering of any service, with any Affiliate except (1) upon
fair and reasonable terms no less favorable to the Parent Guarantor or such
Restricted Subsidiary than might reasonably be obtained in a comparable
arm's-length transaction with an unrelated Person and (2)(A) with respect to any
transaction or series of related transactions involving aggregate consideration
in excess of $10.0 million, such transaction is approved by at least a majority
of the disinterested members of the Board of Directors, if any, of the Parent
Guarantor and the Company, or (B) with respect to any transaction or series of
related transactions involving aggregate consideration in excess of $25.0
million, the Company obtains a written opinion as to the fairness to the Holders
of the Notes of such transaction or series of related transactions issued by an
investment banking, accounting or appraisal firm of national standing; PROVIDED,
HOWEVER, that the requirements set forth in this clause (2) shall not apply in
the case of exchanges of licenses and related assets between the Parent
Guarantor or any Restricted Subsidiaries and AT&T Corp., AT&T Wireless Services,
Inc., Dobson Communications Corporation and any of their respective Subsidiaries
so long as the Fair Market Value of the licenses and related assets exchanged by
the Parent Guarantor or any Restricted Subsidiaries shall not in any single
transaction exceed $50.0 million.

<PAGE>

                  (b) The provisions of Section 4.12(a) shall not prohibit:

                  (i) any transaction solely between the Parent Guarantor and
         any Restricted Subsidiaries or solely between or among Restricted
         Subsidiaries;

                  (ii) the payment of reasonable and customary regular fees and
         indemnity payments to directors of the Parent Guarantor or the Company
         who are not employees of the Parent Guarantor or the Company and the
         payment of reasonable compensation and indemnity payments to officers
         of the Parent Guarantor and the Company;

                  (iii) any payments or other transactions pursuant to any
         tax-sharing agreement between the Parent Guarantor and any other Person
         with which the Parent Guarantor files a consolidated tax return or with
         which the Company is part of a consolidated group for tax purposes;

                  (iv) any Restricted Payments or Investments not prohibited by
         Section 4.07 hereof;

                  (v) any payments or other transactions contemplated by the
         Joint Venture Agreements, as in effect on the Issue Date; or

                  (vi) roaming or similar communications services agreement (x)
         among the Parent Guarantor and/or its Restricted Subsidiaries and a
         Qualified Joint Venture that is not a Restricted Subsidiary or (y)
         between a Qualified Joint Venture that is a Restricted Subsidiary and
         any of its Qualified Joint Venture Partners who are Affiliates of such
         Qualified Joint Venture; PROVIDED, HOWEVER, that in either case any
         such agreement is upon fair and reasonable terms no less favorable to
         the Parent Guarantor or such Restricted Subsidiary (which, in the case
         of clause (y) refers to the relevant Qualified Joint Venture) than
         could be obtained in a comparable arm's-length transaction with an
         unrelated Person.

SECTION 4.13.         LIENS.

                  The Parent Guarantor shall not, and shall not permit any
Restricted Subsidiaries to, directly or indirectly, create, Incur, assume or
suffer to exist any Lien of any kind securing Indebtedness that is either pari
passu with the Notes or any Guarantee of the Notes, as the case may be, or that
is Subordinated Indebtedness, upon any of their property or assets, now owned or
hereafter acquired (other than Permitted Liens), unless all payments due under
this Indenture and the Notes are secured equally and ratably with (or prior to,
in the case of Subordinated Indebtedness) the obligations so secured until such
time as such obligations are no longer secured by such Lien; PROVIDED, HOWEVER,
that this restriction shall not apply to any Lien securing Acquired Indebtedness
created prior to the Incurrence of such Indebtedness by the Parent Guarantor or
any Restricted Subsidiary (and to successive extensions or refinancings
thereof), where such Lien extends only to the assets

                                       75

<PAGE>

that were subject to such Lien prior to the related acquisition by the Parent
Guarantor or its Restricted Subsidiary.

SECTION 4.14.         LIMITATION ON LAYERED INDEBTEDNESS

                  Neither the Parent Guarantor nor any Restricted Subsidiary of
the Parent Guarantor shall directly or indirectly Incur any Indebtedness that by
its terms would expressly rank senior in right of payment to the Notes and rank
subordinate in right of payment to any other Indebtedness of the Parent
Guarantor or that Restricted Subsidiary; PROVIDED, HOWEVER, that no Indebtedness
shall be deemed to be subordinated solely by virtue of being unsecured.

SECTION 4.15.         CORPORATE EXISTENCE.

                  Subject to Article 5 hereof, each of the Company and each
Guarantor shall do or cause to be done all things necessary to preserve and keep
in full force and effect (i) its corporate or limited liability company
existence, as the case may be, and the corporate, limited liability company,
partnership or other existence of each Restricted Subsidiary, in accordance with
the respective organizational documents (as the same may be amended from time to
time) of the Company, such Guarantor or any such Restricted Subsidiary and (ii)
the rights (charter and statutory), licenses and franchises of the Company, such
Guarantor and the Restricted Subsidiaries; PROVIDED, HOWEVER, that the Company
and each Guarantor shall not be required to preserve any such right, license or
franchise, or the corporate, partnership or other existence of any Restricted
Subsidiaries, if the Board of Directors of the Parent Guarantor or the Company
shall each determine that the preservation thereof is no longer desirable in the
conduct of the business of the Company and the Restricted Subsidiaries, taken as
a whole, and that the loss thereof is not adverse in any material respect to the
Holders of the Notes.

SECTION 4.16.         OFFER TO REPURCHASE UPON CHANGE OF CONTROL.

                  (a) If a Change of Control occurs, each Holder shall have the

multiple of $1,000, of the Holder's Notes at an offer price in cash equal to
101% of the aggregate principal amount thereof, plus accrued and unpaid interest
and Liquidated Damages, if any, thereon to the date fixed for repurchase (the
"CHANGE OF CONTROL PAYMENT").

                  (b) Within 30 Business Days following a Change of Control, the
Company shall mail an Offer to Purchase to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase the Notes on the date specified in the notice, which date shall be
no earlier than 30 days and no later than 60 days from the date the notice is
mailed (the "CHANGE OF CONTROL PAYMENT DATE") pursuant to the procedures set
forth in Section 3.09 and described in the notice. The Company shall comply with
the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws and regulations thereunder to the extent those laws and

<PAGE>

regulations are applicable to the repurchase of the Notes as a result of a
Change of Control.

                  (c) On the Change of Control Payment Date, the Company shall,
to the extent lawful, (1) accept for payment all Notes or portions of Notes
properly tendered under the Change of Control Offer; (2) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Notes
or portions of the Notes so tendered; and (3) deliver or cause to be delivered
to the Trustee the Notes so accepted together with an Officers' Certificate in
accordance with Sections 13.04 and 13.05 stating the aggregate principal amount
of Notes or portions of the Notes being purchased by the Company.

                  (d) The Paying Agent shall mail promptly to each Holder of
Notes so tendered the Change of Control Payment for the Notes, and the Trustee
shall, upon receipt of an Authentication Order in accordance with Section 2.02,
promptly authenticate and mail, or cause to be transferred by book entry, to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, PROVIDED, HOWEVER, that each new Note shall be in a
principal amount of $1,000 or an integral multiple of $1,000.

                  (e) The Change of Control provisions described in this Section
4.16 shall be applicable notwithstanding any other provisions of this Indenture.

                  (f) 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 4.16 and purchases all Notes validly
tendered and not withdrawn under the Change of Control Offer.

SECTION 4.17.         LIMITATIONS ON LINE OF BUSINESS.

                  The Parent Guarantor shall not, and shall not permit any
Restricted Subsidiary to, engage in any business other than a Permitted
Business, except to such extent as is not material to the Parent Guarantor and
its Restricted Subsidiaries, taken as a whole.

SECTION 4.18.         PAYMENTS FOR CONSENT.

                  Neither the Parent Guarantor nor any Restricted Subsidiaries
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 Notes unless such consideration is offered to be paid
or is paid to all Holders that consent, waive or agree to amend in the time
frame set forth in the solicitation documents relating to such consent, waiver

                  The Company shall purchase and pledge to the Trustee as
security for the benefit of the Holders the Pledged Securities, in accordance
with the Escrow Agreement, in an amount that will be sufficient upon receipt of
the scheduled interest and/or principal payments on those Pledged Securities, in
the opinion of a nationally recognized firm of independent public accountants
that the Company may select, to provide for the payment in full of the first
four scheduled interest payments due on the Notes. All funds in the Interest

         payable upon exercise of dissenters' rights or for fractional shares,
         shall be issued or distributed to the stockholders of the Parent
         Guarantor or the Company, as applicable;

         Certificate in accordance with Sections 13.04 and 13.05, attaching the
         arithmetic computations to demonstrate compliance with clause (iii) of
         this Section 5.01(a), and an Opinion of Counsel, in each case stating
         that such consolidation, merger or transfer complies with this

         relating to such transaction have been satisfied.

                  Clause (iii) of this Section 5.01(a) above shall not apply if,
in the good faith determination of the Board of Directors of each of the Parent
Guarantor and the Company, the principal purpose of the transaction is to change
the state of incorporation of the Parent Guarantor or the Company, as the case
may be, and the transaction does not have as one of its purposes the evasion of
the foregoing limitations.

                  (b) Except in connection with an Asset Sale effected as a
merger or conveyance, transfer or lease of all or substantially all of the
assets of a Subsidiary Guarantor in which the Parent Guarantor or its applicable

permit any Subsidiary Guarantor to consolidate with or merge with or into, or

         Subsidiary Guaranty;

                  (ii)immediately after giving effect to that 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 the transaction as having been issued by that Person at
         the time of the transaction), no Default or Event of Default shall have
         occurred and be continuing; and

                  (iii) the Company delivers to the Trustee an Officers'
         Certificate in accordance with Sections 13.04 and 13.05, attaching the

         terms of its Guarantee of the Notes and this Indenture in connection
         with any transaction complying with the provisions of Section 4.11.

SECTION 5.02.         SUCCESSOR PERSON SUBSTITUTED.

                  Upon any consolidation or merger, or any sale, assignment,
transfer, lease, conveyance or other disposition of all or substantially all of

accordance with Section 5.01 hereof, the successor Person formed by such
consolidation or into or with which the Parent Guarantor, the Company or any
such Subsidiary Guarantor, as the case may be, is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall

the successor Person and not to the Company, and the provisions of this
Indenture referring to the "Guarantor" shall refer instead to the Successor
Person and not to any Guarantor), and may exercise every right and power of the
Company or the Guarantor, as the case may be, under this Indenture with the same
effect as if such Successor Person had been named as the Company or a Guarantor,
as the case may be, herein; PROVIDED, HOWEVER, that the predecessor Company or
Guarantor, as the case may be, shall not be relieved from the obligation to pay
or Guarantee, respectively, the principal of and interest on the Notes except in
the case of a sale of all or substantially all of the Company's assets that
meets the requirements of Section 5.01 hereof.

                  (i) a court having jurisdiction in the premises enters a

SECTION 6.02.         ACCELERATION.

                  (a) If any Event of Default (other than an Event of Default
specified in clause (i) or (j) of Section 6.01 hereof with respect to the
Company), occurs and is continuing, the Trustee or the Holders of at least 25%
in principal amount of the then outstanding Notes, by written notice to the
Company (and, if such notice is given by such Holders, to the Trustee), may, and
the Trustee at the request of such Holders shall, declare the principal of,
premium, accrued interest and Liquidated Damages, if any, on the Notes to be
immediately due and payable; PROVIDED, HOWEVER, that so long as any Senior
Indebtedness is outstanding, the acceleration will not be effective until the
earlier of (a) an acceleration of any Senior Indebtedness or (b) five Business
Days after the Company's receipt of written notice of the acceleration of the
Notes. Upon such declaration of acceleration, such principal of, premium, if
any, and accrued and unpaid interest and Liquidated Damages, if any, shall be
immediately due and payable; PROVIDED, HOWEVER, that so long as the Senior
Credit Facility is in effect, such declaration shall not become effective until
five Business Days after the receipt of the acceleration notice by the agent
thereunder and the Company.

                                       82

<PAGE>

                  (b) In the event of a declaration of acceleration because an
Event of Default set forth in clause (g) above has occurred and is continuing,
such declaration of acceleration shall be automatically rescinded and annulled
if the event of default triggering such Event of Default pursuant to clause (g)
shall be remedied or cured or waived by the holders of the relevant Indebtedness
within 60 days after the declaration of acceleration with respect thereto.

                  (c) Notwithstanding the foregoing, if an Event of Default
specified in clause (i) or (j) of Section 6.01 hereof occurs with respect to the
Company, the Parent Guarantor or any Guarantor that is a Significant Subsidiary,
the principal of, premium, if any, if any, and accrued and unpaid interest and
Liquidated Damages, if any, on the Notes then outstanding shall be due and
payable immediately without further action or notice on the part of the Trustee
or any Holder.

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, premium,
interest and Liquidated Damages, if any, on the Notes or to enforce the
performance of any provision of the Notes or this Indenture.

                  The Trustee may maintain a proceeding even if it does not
possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder of a Note 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. All remedies
are cumulative to the extent permitted by law.

SECTION 6.04.         WAIVER OF PAST DEFAULTS.

                  At any time after declaration of acceleration, but before a
judgment or decree for the payment of the money due has been obtained by the
Trustee, the Holders of at least a majority in principal amount of the
outstanding Notes by written notice to the Company and to the Trustee, may waive
all past defaults, and rescind and annul a declaration of acceleration and its
consequences if:

                  (a) all existing Events of Default, other than the nonpayment
of the principal of, premium, interest or Liquidated Damages, if any, on the
Notes that have become due solely by such declaration of acceleration, have been
cured or waived; and

                  (b) such rescission would not conflict with any judgment or
decree of a court of competent jurisdiction.

Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no

                                       83

<PAGE>

such waiver shall extend to any subsequent or other Default or Event of
Default or impair any right consequent thereto.

SECTION 6.05.         CONTROL BY MAJORITY.

                  Holders of a majority in principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may involve the Trustee in personal liability or that the Trustee determines in
good faith may be unduly prejudicial to the rights of other Holders of Notes not
joining in the giving of such direction and may take any other action it deems
proper that is not inconsistent with any such direction received for Holders of
Notes.

SECTION 6.06.         LIMITATION ON SUITS.

                  A Holder of a Note may pursue a remedy with respect to this
Indenture or the Notes only if:

                  (a) the Holder of a Note gives to the Trustee written notice
of a continuing Event of Default;

                  (b) the Holders of at least 25% in principal amount of the
then outstanding Notes make a written request to the Trustee to pursue the
remedy;

                  (c) such Holder of a Note or Holders of Notes offer and, if
requested, provide to the Trustee indemnity satisfactory to the Trustee against
any loss, liability or expense;

                  (d) the Trustee does not comply with the request within 60
days after receipt of the request and the offer and, if requested, the provision
of indemnity; and

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

                  A Holder of a Note may not use this Indenture to prejudice the
rights of another Holder of a Note or to obtain a preference or priority over
another Holder of a Note.

SECTION 6.07.         RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

                  Notwithstanding any other provision of this Indenture, the
right of any Holder of a Note to receive payment of principal, premium, interest
and Liquidated Damages, if any, on such Note, on or after the respective due
dates expressed in the Note

                                       84

<PAGE>

(including in connection with an Offer to Purchase), 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(a) or (b)
occurs and is continuing, the Trustee is authorized to recover judgment in its
own name and as Trustee of an express trust against the Company for the whole
amount of principal of, premium, interest and Liquidated Damages, if any, on the
remaining unpaid on such Notes and interest on overdue principal and, to the
extent lawful, interest and such further amount as shall be sufficient to cover
the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09.         TRUSTEE MAY FILE PROOFS OF CLAIM.

                  The Trustee is authorized to 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 (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel) and
the Holders of the Notes allowed in any judicial proceedings relative to the
Company (or any other obligor upon the Notes), its creditors or its property and
shall be entitled and empowered to collect, receive and distribute any money or
other property payable or deliverable on any such claims and any custodian in
any such judicial proceeding is hereby authorized by each Holder to make such
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 to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 7.07 hereof. To the extent that the payment of any such
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 7.07 hereof out
of the estate in any such proceeding, shall be denied for any reason, payment of
the same shall be secured by a Lien on, and shall be paid out of, any and all
distributions, dividends, money, securities and other properties that the
Holders may be entitled to receive in such proceeding whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Notes or the rights of any Holder, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

SECTION 6.10.         PRIORITIES.

                  If the Trustee collects any money pursuant to this Article, it
shall pay out the money in the following order:

                                       85

<PAGE>

                  FIRST: to the Trustee, its agents and attorneys for amounts

and expenses of collection;

                  SECOND: to Holders of Notes for amounts due and unpaid on the
Notes for principal, premium, interest, and Liquidated Damages, if any, ratably,

if any, respectively; and

                  THIRD: to the Company or to such party as a court of competent
jurisdiction shall direct.

                  The Trustee may fix a record date and payment date for any
payment to Holders of Notes pursuant to this Section 6.10.

SECTION 6.11.         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 a 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, against any party litigant in the suit, having due
regard to the merits and good 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 of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more
than 10% in principal amount of the then outstanding Notes.

SECTION 6.12.         RESTORATION OF RIGHTS AND REMEDIES.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then, and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Company, Trustee and the Holders shall
continue as though no such proceeding had been instituted.

SECTION 6.13.         RIGHTS AND REMEDIES CUMULATIVE.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or wrongfully taken Notes in Section
2.07, no right or remedy herein conferred upon or reserved to the Trustee or to
the Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or

                                       86

<PAGE>

employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.

SECTION 6.14.         DELAY OR OMISSION NOT WAIVER.

                  No delay or omission of the Trustee or of any Holder to
exercise any right or remedy accruing upon any Event of Default shall impair any
such right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein. Every right and remedy given by this Article 6 or by law
to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case
may be.

SECTION 7.01.         DUTIES OF TRUSTEE.

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

if it is known to the Trustee, the Trustee shall mail to Holders of Notes a
notice of the Default or Event of Default within 90 days after it occurs. Except
in the case of a Default or Event of Default in payment of principal of,

Holders of the Notes a brief report dated as of such reporting date that
complies with TIA Section 313(a) (but if no event described in TIA Section
313(a) has occurred within the twelve months preceding the reporting date, no
report need be transmitted). The Trustee also shall comply with TIA Section

SECTION 7.07.         COMPENSATION AND INDEMNITY.

                  The Company shall pay to the Trustee from time to time such
compensation for its acceptance of this Indenture and services hereunder as
shall be agreed upon in writing. The Trustee's compensation shall not be limited
by any law on compensation of a Trustee of an express trust. The Company shall

advances and expenses Incurred or made by it in addition to the compensation for
its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

                  The Company shall indemnify the Trustee against any and all
losses, liabilities or expenses (including reasonable fees and disbursements of
counsel) Incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, including the costs and

negligence or bad faith. The Trustee shall notify the Company promptly of any
claim for which it may seek indemnity. Failure by the Trustee to so

                                       90

<PAGE>

notify the Company shall not relieve the Company of its obligations
hereunder. The Company shall defend the claim and the Trustee shall cooperate

the Trustee shall have, and the Company hereby grants, a Lien prior to the Notes

trust to pay principal, interest and Liquidated Damages, if any, on particular
Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

Event of Default specified in Section 6.01(i) or (j) hereof occurs, the expenses
and the compensation for the services (including the fees and expenses of its
agents and counsel) are intended to constitute expenses of administration under
any Bankruptcy Law.

                  The Trustee shall comply with the provisions of TIA Section
313(b)(2) to the extent applicable.

SECTION 7.08.         REPLACEMENT OF TRUSTEE.

acceptance of appointment as provided in this Section.

                  The Trustee may resign in writing at any time and be
discharged from the trust hereby created by so notifying the Company. The
Holders of Notes of a majority in principal amount of the then outstanding Notes
may remove the Trustee by so notifying the Trustee and the Company in writing.
The Company may remove the Trustee if:

                  (a) the Trustee fails to comply with Section 7.10 hereof;

                  (b) the Trustee is adjudged a bankrupt or an insolvent or an
order for relief is entered with respect to the Trustee under any Bankruptcy
Law;

or its property; or

                  (d) the Trustee becomes incapable of acting.

                                       91

<PAGE>

                  If the Trustee resigns or is removed or if a vacancy exists in
the office of Trustee for any reason, the Company shall promptly appoint a
successor Trustee. Within one year after the successor Trustee takes office, the
Holders of a majority in principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

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

who has been a Holder of a Note for at least six months, fails to comply with
Section 7.10, such Holder of a Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of 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 Holders of the Notes. Subject to the Lien provided for in Section
7.07 hereof, the retiring Trustee shall promptly transfer all property held by
it as Trustee to the successor Trustee; PROVIDED, HOWEVER, that all sums owing
to the Trustee hereunder shall have been paid. Notwithstanding replacement of
the Trustee pursuant to this Section 7.08, the Company's obligations under
Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.09.         SUCCESSOR TRUSTEE BY MERGER, ETC.

                  If the Trustee consolidates, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation or national banking corporation, the Successor Person or national
banking corporation without any further act shall be the successor Trustee.

SECTION 7.10.         ELIGIBILITY; DISQUALIFICATION.

                  There shall at all times be a Trustee hereunder that is a
corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise
corporate Trustee power, that is subject to supervision or examination by
federal or state authorities and that has a combined capital and surplus of at
least $50 million as set forth in its most recent published annual report of
condition.

                  This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b) PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA Section 310(b)(1) any

                                       92

<PAGE>

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 exclusions set forth in TIA Section 310(b)(1)
are met.

SECTION 7.11.         PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

                  The Trustee is subject to 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
therein.

                                   ARTICLE 8.

the purposes of Section 8.05 hereof and the other Sections of this Indenture
referred to in clauses (a) and (b) below, and to have satisfied all its other
obligations under such Notes and this Indenture (and the Trustee, on demand of

for accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Notes, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such covenant or by reason of any reference in any such

Section 6.01 hereof, but, except as specified above, the remainder of this
Indenture and such Notes shall be unaffected thereby. In addition, upon the
Company's exercise under Section 8.01 hereof of the option applicable to this
Section 8.03 hereof, subject to the satisfaction of the conditions set forth in
Section 8.04 hereof, Sections 6.01(c) through 6.01(f) hereof shall not

Defeasance if:

                  (a) the Company has irrevocably deposited with the Trustee, in
trust, for the benefit of the Holders, cash in United States dollars,
non-callable U.S. Government Securities, or a combination thereof, in such
amounts as shall be sufficient, in the opinion of a nationally recognized firm
of independent public accountants, to pay the principal of, premium, if any, and
accrued interest and Liquidated Damages, if any, on the outstanding Notes on the
Stated Maturity of such payments in accordance with the terms of the Notes and
this Indenture;

                  (b) the Company has delivered to the Trustee

                (i)   either

                           (A) an Opinion of Counsel to the effect that Holders
                  shall not recognize income, gain or loss for federal income
                  tax purposes as a result of the Company's exercise of its
                  option under this Article Eight and shall be subject to
                  federal income tax on the same amount and in the same

<PAGE>

                  manner and at the same times as would have been the case if
                  such deposit, defeasance and discharge had not occurred, which
                  opinion of counsel must be based upon (and accompanied by a
                  copy of) a ruling of the Internal Revenue Service to the same
                  effect unless there has been a change in applicable federal
                  income tax law after the Issue Date such that a ruling is no
                  longer required or

                           (B) a ruling directed to the Trustee received from
                  the Internal Revenue Service to the same effect as the
                  aforementioned opinion of counsel and

                (ii)  an Opinion of Counsel to the effect that the creation of
         the defeasance trust does not violate the Investment Company Act of
         1940 and after the passage of 93 days following the deposit (except
         with respect to any trust funds for the account of any Holder who may
         be deemed an "insider" for purposes of the United States Bankruptcy
         Code, after one year following the deposit), the trust funds shall not
         be subject to the effect of Section 547 of the United States Bankruptcy
         Code or Section 15 of the New York Debtor and Creditor Law,

                  (c) immediately after giving effect to such deposit on a pro
forma basis, no Default or Event of Default shall have occurred and be
continuing on the date of such deposit, and such deposit shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound, and

                  (d) if at such time the Notes are listed on a national
securities exchange, the Company has delivered to the Trustee an Opinion of
Counsel to the effect that the Notes shall not be delisted as a result of such
deposit, defeasance and discharge.

                  (e) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, in each case stating that all conditions
precedent provided for herein relating to the defeasance contemplated by this
Section 8.04 have been satisfied in accordance with Sections 13.04 and 13.05.

SECTION 8.05.         DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN
TRUST; OTHER MISCELLANEOUS PROVISIONS.

                  Subject to Section 8.06 hereof, all money and non-callable
U.S. Government Securities (including the proceeds thereof) deposited with the

8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the
outstanding Notes shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Notes and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company acting as
Paying Agent) as the Trustee may determine, to the Holders of such Notes of all
sums due and to become due thereon in respect of principal, premium,

                                      95

notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon the request of the Company any money or non-callable U.S. Government
Securities held by it as provided in Section 8.04 hereof which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee (which may be the opinion
delivered under Section 8.04(a) hereof), are in excess of the amount thereof
that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

SECTION 8.06.         REPAYMENT TO COMPANY.

Holder of such Note shall thereafter, as an unsecured creditor, look only to the
Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
Trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in The New York Times and The
Wall Street Journal (national edition), notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such notification or publication, any unclaimed balance of such
money then remaining shall be repaid to the Company.

SECTION 8.07.         REINSTATEMENT.

                  If the Trustee or Paying Agent is unable to apply any United
States dollars or non-callable U.S. Government Securities in accordance with
Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, then the Company's obligations under
this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as
the Trustee or Paying Agent is permitted to apply all such money in

                                      96

<PAGE>

accordance with Section 8.02 or 8.03 hereof, as the case may be; PROVIDED,
HOWEVER, that, if the Company makes any payment of principal of, premium, if
any, interest, or Liquidated Damages, if any, on any Note following the
reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such Notes to receive such payment from the money
held by the Trustee or Paying Agent.

                                   ARTICLE 9.

                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01.         WITHOUT CONSENT OF HOLDERS OF NOTES.

                  Notwithstanding Section 9.02 of this Indenture, the Parent
Guarantor, the Company, the Subsidiary Guarantors and the Trustee may amend or
supplement this Indenture or the Notes without the consent of any Holder of a
Note:

                  (a) to cure any ambiguity, defect or inconsistency;

                  (b) to provide for uncertificated Notes in addition to or in
place of certificated Notes;

                  (c) to provide for the assumption of the Company's obligations
to the Holders of the Notes by a successor to the Company pursuant to Article 5
hereof;

                  (d) to make any change that would provide any additional
rights or benefits to the Holders of the Notes or that does not adversely affect
the legal rights hereunder of any Holder of the Note; or

                  (e) to comply with requirements of the Commission in order to
effect or maintain the qualification of this Indenture under the TIA;

PROVIDED, HOWEVER, that no amendment may be made to Article Eleven hereof that
adversely affects the rights of any Holder of Senior Indebtedness of the Company
or a Subsidiary Guarantor then outstanding unless the Holders of such Senior
Indebtedness (or their Representative) consents to such change.

                  Upon the request of the Company accompanied by a resolution of
its Board of Directors authorizing the execution of any such amended or
supplemental Indenture, and upon receipt by the Trustee of the documents
described in Section 7.02 hereof, the Trustee shall join with the Company in the
execution of any amended or supplemental Indenture authorized or permitted by
the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture that affects its
own rights, duties or immunities under this Indenture or otherwise.

                                      97

SECTION 9.02.         WITH CONSENT OF HOLDERS OF NOTES.

                  (a) Except as provided below in this Section 9.02, the Company
and the Trustee may amend or supplement this Indenture (including Sections 3.09,
4.11 and 4.16 hereof) and the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the Notes
including Additional Notes, if any, then outstanding voting as a single class
(including consents obtained in connection with a tender offer or exchange offer
for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof,
any existing Default or Event of Default (other than a Default or Event of
Default in the payment of the principal of, premium, if any, interest or
Liquidated Damages, if any, on the Notes, except a payment default resulting
solely from an acceleration that has been rescinded) or compliance with any
provision of this Indenture or the Notes may be waived with the consent of the
Holders of a majority in principal amount of the then outstanding Notes,
including Additional Notes, if any, voting as a single class (including consents
obtained in connection with a tender offer or exchange offer for, or purchase
of, the Notes).

                  (b) Upon the request of the Company accompanied by a
resolution of its Board of Directors authorizing the execution of any such
amended or supplemental Indenture, and upon the filing with the Trustee of
evidence satisfactory to the Trustee of the consent of the Holders of Notes as
aforesaid, and upon receipt by the Trustee of the documents described in Section
7.02 hereof, the Trustee shall join with the Company in the execution of such
amended or supplemental Indenture unless such amended or supplemental Indenture
directly affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise, in which case the Trustee may in its discretion, but
shall not be obligated to, enter into such amended or supplemental Indenture.

                  (c) It shall not be necessary for the consent of the Holders
of Notes under this Section 9.02 to approve the particular form of any proposed
amendment or waiver, but it shall be sufficient if such consent approves the
substance thereof.

                  (d) After an amendment, supplement or waiver under this
Section 9.02 becomes effective, the Company shall mail to the Holders of Notes
affected thereby a notice briefly describing the amendment, supplement or
waiver. Any failure of the Company to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such amended
or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof,
the Holders of a majority in aggregate principal amount of the Notes, including
Additional Notes, if any, then outstanding voting as a single class may waive
compliance in a particular instance by the Company with any provision of this
Indenture or the Notes. However, without the consent of each Holder affected, an
amendment or waiver under this Section 9.02 may not (with respect to any Notes
held by a non-consenting Holder):

                (i)   change the Stated Maturity of the principal of, or any
         installment of interest on, any Notes,

                                      98

<PAGE>

                (ii)  reduce the principal amount of, premium, if any, interest
         or Liquidated Damages, if any, on any Notes,

                (iii) change the place or currency of payment of principal of
         premium, if any, interest or Liquidated Damages, if any, on any Notes,

                (iv)  impair the right to institute suit for the enforcement of
         any payment on or after the Stated Maturity (or, in the case of a
         redemption, on or after the redemption date) of any Notes,

                (v)   reduce the above-stated percentage of outstanding Notes
         the consent of whose Holders is necessary to modify or amend this
         Indenture,

                (vi)  waive a default in the payment of principal of, premium,
         or interest or Liquidated Damages, if any, on, the Notes, or

                (vii) reduce the percentage of aggregate principal amount of
         outstanding Notes the consent of whose Holders is necessary for waiver
         of compliance with certain provisions of this Indenture or for waiver
         of certain defaults.

                  (e) Without the consent of the Holders of 66 2/3% in aggregate
principal amount of the Notes then outstanding, no amendment may:

                (i)   make any change to the provisions of Article Eleven hereof
         that adversely affects the rights of any Holder of Notes; or

                (ii)  modify a Guarantee in any manner adverse to the Holders of
         Notes.

SECTION 9.03.         COMPLIANCE WITH TRUST INDENTURE ACT.

                  Every amendment or supplement to this Indenture or the Notes
shall be set forth in an amended or supplemental Indenture that complies with
the TIA as then in effect.

SECTION 9.04.         REVOCATION AND EFFECT OF CONSENTS.

                  Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder of a Note is a continuing consent by the Holder of a
Note and every subsequent Holder of a Note or portion of a Note that evidences
the same debt as the consenting Holder's Note, even if notation of the consent
is not made on any Note. However, any such Holder of a Note or subsequent Holder
of a Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

                                      99

<PAGE>

SECTION 9.05.         NOTATION ON OR EXCHANGE OF NOTES.

                  The Trustee may place an appropriate notation about an
amendment, supplement or waiver on any Note thereafter authenticated. The
Company in exchange for all Notes may issue and the Trustee shall, upon receipt
of an Authentication Order, authenticate new Notes that reflect the amendment,
supplement or waiver.

                  Failure to make the appropriate notation or issue a new Note
shall not affect the validity and effect of such amendment, supplement or
waiver.

SECTION 9.06.         TRUSTEE TO SIGN AMENDMENTS, ETC.

                  The Trustee shall sign any amended or supplemental Indenture
authorized pursuant to this Article Nine if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
The Company may not sign an amendment or supplemental Indenture until the Board
of Directors approves it. In executing any amended or supplemental indenture,
the Trustee shall be entitled to receive and (subject to Section 7.01 hereof)
shall be fully protected in relying upon, in addition to the documents required
by Section 13.04 hereof, an Officer's Certificate and an Opinion of Counsel
stating that the execution of such amended or supplemental indenture is
authorized or permitted by this Indenture.

                                   ARTICLE 10.

                             GUARANTEES OF THE NOTES

SECTION 10.01.        GUARANTEES.

                  Subject to Articles Ten and Eleven, each Guarantor hereby
jointly and severally irrevocably and unconditionally guarantees, as a primary
obligor and not merely as a surety, to each Holder and to the Trustee and its
successors and assigns (a) the full and punctual payment when due, whether at
Stated Maturity, by acceleration, by redemption or otherwise, of all obligations
of the Company under this Indenture (including obligations to the Trustee) and
the Notes, whether for payment of principal of, interest on or Liquidated
Damages in respect of, the Notes and all other monetary obligations of the
Company under this Indenture and the Notes and (b) the full and punctual
performance within applicable grace periods of all other obligations of the
Company whether for expenses, indemnification or otherwise under this Indenture
and the Notes (all the foregoing being hereinafter collectively called the
"GUARANTEED OBLIGATIONS") by executing a Guarantee. Each Guarantor further
agrees that the Guaranteed Obligations may be extended or renewed, in whole or
in part, without notice or further assent from each such Guarantor, and that
each such Guarantor shall remain bound under Articles Ten or Eleven
notwithstanding any extension or renewal of any Guaranteed Obligation.

                                     100

<PAGE>

                  Each 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 non-payment. Each Guarantor waives notice of any default
under the Notes or the Guaranteed Obligations. The obligations of each Guarantor
hereunder shall not be affected by (a) 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 under this Indenture, the Notes or any other
agreement or otherwise; (b) any extension or renewal of any thereof; (c) any
rescission, waiver, amendment or modification of any of the terms or provisions
of this Indenture, the Notes or any other agreement; (d) the release of any
security held by any Holder or the Trustee for the Guaranteed Obligations or any
of them; (e) the failure of any Holder or Trustee to exercise any right or
remedy against any other Guarantor of the Guaranteed Obligations; or (f) any
change in the ownership of such Guarantor, except as provided in Section
10.02(b).

                  Each Guarantor hereby waives any right to which it may be
entitled to have its obligations hereunder divided among the Guarantors, such
that such Guarantor's obligations would be less than the full amount claimed.
Each Guarantor hereby waives any right to which it may be entitled to have the
assets of the Company first be used and depleted as payment of the Company's or
such Guarantor's obligations hereunder prior to any amounts being claimed from
or paid by such Guarantor hereunder. Each Guarantor hereby waives any right to
which it may be entitled to require that the Company be sued prior to an action
being initiated against such Guarantor.

                  Each Guarantor further agrees that its 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.

                  Each Guarantor agrees, and each Holder by accepting a
Guarantee agrees, that the obligations of each Guarantor under its Guarantee
pursuant to this Article Ten, shall be junior and subordinated to the Senior
Indebtedness of such Guarantor (including without limitation, guarantees of
Obligations arising under the Senior Credit Facility) on the same basis as the
Notes are junior and subordinated to the Senior Indebtedness. For purposes of
the foregoing sentence, the Trustee and the Holders shall have the rights to
receive and/or retain payments by any of the Guarantors, or to take or sustain
any enforcement actions with respect to such Guarantees, only at such times as
they may receive and/or retain payments or undertake and sustain enforcement
actions in respect of the Notes pursuant to Article Eleven.

                  Except as expressly set forth in Sections 8.01, 10.02, and
10.06, the obligations of each 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

                                     101

<PAGE>

limiting the generality of the foregoing, the obligations of each 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 Notes 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 any Guarantor or would
otherwise operate as a discharge of any Guarantor as a matter of law or
equity.

                  Each Guarantor agrees that its Guarantee shall remain in full
force and effect until payment in full of all the Guaranteed Obligations (except
as otherwise provided in Section 12.01). Each 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 Guaranteed 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
Guarantor by virtue hereof, upon the failure of the Company to pay the principal
of or interest on any Guaranteed 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 Guaranteed Obligation, each 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 (i) the unpaid principal amount of such Guaranteed Obligations,
(ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the
extent not prohibited by law) and (iii) all other monetary obligations of the
Company to the Holders and the Trustee.

                  Each Guarantor agrees that it shall not be entitled to any
right of subrogation in relation to the Holders in respect of any Guaranteed
Obligations guaranteed hereby until payment in full of all Guaranteed
Obligations and all obligations to which the Guaranteed Obligations are
subordinated as provided in Article Eleven. Each Guarantor further agrees that,
as between it, on the one hand, and the Holders and the Trustee, on the other
hand, (x) the maturity of the Guaranteed Obligations guaranteed hereby may be
accelerated as provided in Article Six (including, without limitation, with
respect to the notice required to be given to holders of Senior Indebtedness
under Section 6.02) for the purposes of any Guarantee herein, notwithstanding
any stay, injunction or other prohibition preventing such acceleration in
respect of the Guaranteed Obligations guaranteed hereby, and (y) in the event of
any declaration of acceleration of such Guaranteed Obligations as provided in
Article Six, such Guaranteed Obligations (whether or not due and payable) shall
forthwith become due and payable by such Guarantor for the purposes of this
Section 10.01.

                                     102

<PAGE>

                  Each Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees and expenses) Incurred by the
Trustee or any Holder in enforcing any rights under this Section 10.01.

                  Upon request of the Trustee, each Guarantor shall execute and
deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purpose of this Indenture.

SECTION 10.02.        ADDITIONAL GUARANTEES.

                  The Company shall cause any Subsidiary that is designated as a
Restricted Subsidiary in accordance with this Indenture to promptly (a) execute
and deliver to the Trustee a supplemental indenture pursuant to which such
Restricted Subsidiary shall unconditionally guarantee, on a senior subordinated,
unsecured basis, all of the Company's obligations under the Notes and this
Indenture on the terms set forth herein and therein and (b) deliver to the
Trustee an Opinion of Counsel and an Officers' Certificate in accordance with
Sections 13.04 and 13.05 to the effect that, such supplemental indenture has
been duly authorized, executed and delivered by such Subsidiary Guarantor and
that, subject to the application of bankruptcy, insolvency, moratorium,
fraudulent conveyance or transfer and other similar laws relating to creditors'
rights generally and to the principles of equity, whether considered in a
proceeding at law or in equity, the Subsidiary Guaranty of such Subsidiary
Guarantor is a legal, valid and binding obligation of such Subsidiary Guarantor,
enforceable against such Subsidiary Guarantor in accordance with its terms.

SECTION 10.03.        LIMITATION ON GUARANTOR LIABILITY.

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

                  (b) A Guarantee as to any Guarantor shall terminate and be of
no further force or effect and such Guarantor shall be deemed to be released
from all obligations under this Article Ten (i) in the event that such Guarantor
no longer has outstanding, other than the Guarantee, any Indebtedness (in the
case of a Domestic Restricted Subsidiary) or Material Indebtedness (in the case
of a Foreign Restricted Subsidiary) or (ii) upon (x) the merger or consolidation
of such Guarantor with or into any Person other than the Company or a Subsidiary
or Affiliate of the Company where such Guarantor is not the surviving entity of
such consolidation or merger or (y) the sale by the Company or any Subsidiary of
the Company (or any pledgee of the Company) of a majority of the Capital Stock
of such Guarantor, where, after such sale, such Guarantor is no longer a
Subsidiary of the Company; provided, however, that each such merger,
consolidation or

                                     103

<PAGE>

sale (or, in the case of a sale by such a pledgee, the disposition of the
proceeds of such sale) shall comply with Section 4.11 and Section 5.01(b). At
the written request of the Company, the Trustee shall execute and deliver an
appropriate instrument evidencing such release.

SECTION 10.04.        SUCCESSORS AND ASSIGNS.

                  This Article Ten shall be binding upon each Guarantor and its
successors and assigns and shall inure 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 Notes shall automatically
extend to and be vested in such transferee or assignee, all subject to the terms
and conditions of this Indenture.

SECTION 10.05.        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 Ten 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 Ten at law, in
equity, by statute or otherwise.

SECTION 10.06.        MODIFICATION.

                  No modification, amendment or waiver of any provision of this
Article Ten, nor the consent to any departure by any 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
Guarantor in any case shall entitle such Guarantor to any other or further
notice or demand in the same, similar or other circumstances.

                                   ARTICLE 11.

                                  SUBORDINATION

SECTION 11.01.        AGREEMENT TO SUBORDINATE.

                  The Company and each Guarantor agrees, and each Holder by
accepting a Note agrees, that the Indebtedness evidenced by, and all "payments"
on and "distributions" on or with respect to, the Notes and any Guarantee of the
Notes is subordinated in right of payment, to the extent and in the manner
provided in this Article Eleven, to the prior payment in full of all Senior
Indebtedness (whether outstanding on

                                     104

<PAGE>

the date hereof or hereafter created, Incurred, assumed or guaranteed), and
that the subordination is for the benefit of the holders of Senior
Indebtedness.

SECTION 11.02.        LIQUIDATION; DISSOLUTION; BANKRUPTCY.

                  Upon any payment or distribution to creditors of the Company
or any Guarantor in a liquidation or dissolution of the Company or the
Guarantors or in a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to the Company or any Guarantor or their respective
property, an assignment for the benefit of creditors or any marshaling of the
Company's and any Guarantor's assets and liabilities, the holders of Senior
Indebtedness shall be entitled to receive payment in full of all Obligations due
in respect of such Senior Indebtedness (including interest after the
commencement of any such proceeding at the rate specified in the applicable
Senior Indebtedness) before the Holders of Notes shall be entitled to receive
any payment or distribution with respect to the Notes or any Guarantee of the
Notes, and until all Obligations with respect to Senior Indebtedness are paid in
full, any payment or distribution to which the Holders of Notes would be
entitled shall be made to the holders of Senior Indebtedness (except that
Holders of Notes may receive and retain Permitted Junior Securities and payments
made from the Interest Reserve Account or the trust described under Article
Eight if such funds were deposited in accordance with, and to the extent
permitted by, this Article Eleven).

SECTION 11.03.        DEFAULT ON DESIGNATED SENIOR INDEBTEDNESS.

                  (a) The Company and the Guarantors may not make any payments
or distributions with respect to the Notes or any Guarantee of the Notes if (i)
any Designated Senior Indebtedness is not paid when due (whether at maturity, by
acceleration, lapse of time, demand or otherwise) or (ii) any other default on
Designated Senior Indebtedness occurs and the maturity of such Designated Senior
Indebtedness is accelerated in accordance with its terms unless, in either case,
the default has been cured or waived and any such acceleration has been
rescinded or such Designated Senior Indebtedness has been paid in full. However,
the Company and the Guarantors may and shall pay the Notes without regard to the
foregoing if the Company and the Trustee receive written notice approving such
payment from the Representative of the Designated Senior Indebtedness with
respect to which either of the events set forth in clause (i) or (ii) of the
immediately preceding sentence has occurred and is continuing.

                  (b) If a default exists (or arises as a result of any payment
or distribution with respect to the Notes or Guarantee of the Notes) (other than
a default described in clause (i) or (ii) of clause (a) above) with respect to
any Designated Senior Indebtedness pursuant to which the maturity thereof may be
accelerated immediately without further notice (except such notice as may be
required to effect such acceleration) or the expiration of any applicable grace
periods, the Company and the Guarantors may not pay the Notes or Guarantees of
the Notes for a period (a "PAYMENT BLOCKAGE PERIOD") commencing upon the receipt
by the Trustee (with a copy to the Company) of written

                                     105

<PAGE>

notice (a "PAYMENT BLOCKAGE NOTICE") of such default from the Representative
of the holders of such Designated Senior Indebtedness specifying an election
to effect a Payment Blockage Period. Upon such receipt, payments on the Notes
and Guarantees of the Notes shall be permitted and required to resume,

                (i)   in the case of a payment default, upon the date on which
         such default is cured or waived, and,

                (ii)  in the case of a nonpayment default, 179 days thereafter
         (or earlier if such Payment Blockage Period is terminated (A) by
         written notice to the Trustee and the Company from the Person or
         Persons who gave such Payment Blockage Notice that such default has
         been cured or waived, (B) because the default giving rise to such
         Payment Blockage Notice is no longer continuing or (C) because such
         Designated Senior Indebtedness has been repaid in full, unless the
         maturity of the Designated Senior Indebtedness has been accelerated).

                  (c) Notwithstanding the provisions of clause (b) of this
Section 11.03 (but subject to the first sentence of clause (a) of this Section
11.03), unless the holders of such Designated Senior Indebtedness or the
Representative of such holders have accelerated the maturity of such Designated
Senior Indebtedness, the Company may resume payments on the Notes after the end
of such Payment Blockage Period. The Notes shall not be subject to more than one
Payment Blockage Period in any consecutive 360-day period, irrespective of the
number of defaults with respect to Designated Senior Indebtedness during such
period. No nonpayment default that existed or was continuing on the date of
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice unless such default shall have
been waived for a period of not less than 90 days. Following the expiration of
any period during which the Company is prohibited from making payments on the
Notes pursuant to a Payment Blockage Notice, the Company shall be obligated to
resume making any and all required payments in respect of the Notes, including
any missed payments, unless the maturity of any Designated Senior Indebtedness
has been accelerated, and such acceleration remains in full force and effect.

                  (d) The Company shall give prompt written notice to the
Trustee of any default in the payment of any Senior Indebtedness or any
acceleration under any Senior Indebtedness or under any agreement pursuant to
which Senior Indebtedness may have been issued. Failure to give such notice
shall not affect the subordination of the Notes to the Senior Indebtedness or
the application of the other provisions provided in this Article Eleven.

                  (e) So long as any Indebtedness is outstanding under the
Senior Credit Facility, only the Administrative Agent under such Senior Credit
Facility shall be permitted to effect a Payment Blockage Period.

SECTION 11.04.        ACCELERATION OF NOTES.

                  If payment of the Notes is accelerated because of a Default,
the Company shall promptly notify holders of Senior Indebtedness of the
acceleration.

SECTION 11.05.        WHEN DISTRIBUTION MUST BE PAID OVER.

                  In the event that the Trustee receives or is holding, or any
Holder receives, any payment or distribution with respect to the Notes or any
Guaranty of the Notes, and such payment is prohibited by Section 11.02 or 11.03
hereof (except with respect to payments made from the Interest Reserve Account
or the trust described under Article Eight if such funds were deposited in
accordance with, and to the extent permitted by, this Article Eleven), such
payment or distribution shall be held by the Trustee or such Holder, in trust
for the benefit of, and shall be paid forthwith over and delivered to, the
holders of Senior Indebtedness as their interests may appear or their
Representative under this Indenture or other agreement (if any) pursuant to
which Senior Indebtedness may have been issued, as their respective interests
may appear, for application to the payment of all Obligations with respect to
the Senior Indebtedness remaining unpaid to the extent necessary to pay such
Obligations in full in accordance with their terms, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

                  With respect to the holders of Senior Indebtedness, the
Trustee undertakes to perform only such obligations on the part of the Trustee
as are specifically set forth in this Article Eleven, and no implied covenants
or obligations with respect to the holders of Senior Indebtedness shall be read
into this Indenture against the Trustee. The Trustee shall not be deemed to owe
any fiduciary duty to the holders of Senior Indebtedness, and shall not be
liable to any such holders if the Trustee shall mistakenly pay over or
distribute to or on behalf of Holders or the Company or any other Person money
or assets to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article Eleven, except if such payment is made as a result of the
willful misconduct or gross negligence of the Trustee.

SECTION 11.06.        NOTICE BY THE COMPANY.

                  The Company shall promptly notify the Trustee and the Paying
Agent of any facts known to the Company that would cause a payment of any
Obligations with respect to the Notes or Guarantees of the Notes to violate this
Article Eleven, but failure to give such notice shall not affect the
subordination of the Notes or the Guarantees of the Notes to the Senior
Indebtedness as provided in Articles Ten and Eleven.

SECTION 11.07.        SUBROGATION.

                  After all Senior Indebtedness is paid in full and until the
Notes are paid in full, Holders shall be subrogated (equally and ratably with
all other Indebtedness pari passu with the Notes) to the rights of holders of
Senior Indebtedness to receive

                                     107

<PAGE>

distributions applicable to Senior Indebtedness to the extent that
distributions otherwise payable to the Holders have been applied to the
payment of Senior Indebtedness. A distribution made under this Article Eleven
to holders of Senior Indebtedness that otherwise would have been made to
Holders is not, as between the Company and Holders, a payment by the Company
on the Notes.

                  If any payment or distribution to which the Holders would
otherwise have been entitled but for the provisions of this Article Eleven shall
have been applied, pursuant to the provisions of this Article Eleven, to the
payment of all amounts payable under the Senior Indebtedness, then and in such
case the Holders shall be entitled to receive from the holders of such Senior
Indebtedness at the time outstanding any payments or distributions received by
such holders of such Senior Indebtedness in excess of the amount sufficient to
pay all amounts payable under or in respect of such Senior Indebtedness in full;
PROVIDED, HOWEVER, that such payments or distributions shall be paid first pro
rata to Holders that previously paid amounts then pro rata to all Holders.

SECTION 11.08.        RELATIVE RIGHTS.

                  This Article Eleven defines the relative rights of Holders and
holders of Senior Indebtedness. Nothing in this Indenture shall:

                  (a) impair, as between the Company and Holders, the obligation
of the Company, which is absolute and unconditional, to pay principal, premium,
interest and Liquidated Damages, if any, on the Notes in accordance with their
terms;

                  (b) affect the relative rights of Holders and creditors of the
Company other than their rights in relation to holders of Senior Indebtedness;
or

                  (c) prevent the Trustee or any Holder from exercising its
available remedies upon a Default, subject to the rights of holders and owners
of Senior Indebtedness to receive distributions and payments otherwise payable
to Holders.

                  If the Company fails because of this Article Eleven to pay
principal, premium, interest and Liquidated Damages, if any, on a Note on the
due date, the failure is still a Default.

SECTION 11.09.        SUBORDINATION MAY NOT BE IMPAIRED BY THE COMPANY.

                  No right of any holder of Senior Indebtedness to enforce the
subordination of the Indebtedness evidenced by the Notes shall be impaired by
any act or failure to act by the Company or any Holder or by the failure of the
Company or any Holder to comply with this Indenture.

                  Subject to the other provisions of this Indenture, the holders
of the Senior Indebtedness may, at any time and from time to time, without the
consent of or notice to the Trustee or the Holders, without incurring
responsibility to the Holders, and without

                                     108

<PAGE>

impairing or releasing the subordination provided in Articles Ten and Eleven,
or the obligations hereunder of the Holders to the holders of the Senior
Indebtedness, do any one or more of the following: (a) change in the manner,
place, or terms of payment, or extend the time of payment of, or renew or
alter, Senior Indebtedness or any instrument evidencing the same or any
agreement under which the Senior Indebtedness is outstanding or secured; (b)
sell, exchange, release, or otherwise deal with any property pledged,
mortgaged, or otherwise securing the Senior Indebtedness; (c) release any
Person liable in any manner for the collection of Senior Indebtedness; and
(d) exercise or refrain from exercising any rights against the Company, the
Guarantor or any other Person; PROVIDED, HOWEVER, that this provision shall
not in any way permit the Company or any Guarantor to take any action
otherwise prohibited by the Indenture.

SECTION 11.10.        DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

                  Whenever a distribution is to be made or a notice given to
holders of Senior Indebtedness, the distribution may be made and the notice
given to their Representative.

                  Upon any payment or distribution of assets of the Company or
any Guarantor referred to in this Article Eleven, the Trustee and the Holders
shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other Person making any distribution to the
Trustee or to the Holders for the purpose of ascertaining the Persons entitled
to participate in such distribution (so long as the existence of the
subordination provisions of Articles Ten and Eleven have been brought to the
attention of such court, Representative, liquidating trustee or agent, or other
Person), the holders of the Senior Indebtedness and other Indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
Eleven.

SECTION 11.11.        RIGHTS OF TRUSTEE AND PAYING AGENT.

                  Notwithstanding the provisions of this Article Eleven or any
other provision of this Indenture, the Trustee shall not be charged with
knowledge or notice of the existence of any facts that would prohibit the making
of any payment or distribution by the Trustee, and the Trustee and the Paying
Agent may continue to make payments on the Notes (subject to the requirement
under Section 11.05 that the Trustee hold any payment made in violation of
Sections 11.02 and 11.03), unless a Responsible Officer of the Trustee shall
have received at its Corporate Trust Office prior to the due date of such
payment written notice of facts that would cause the payment of any principal,
premium, interest and Liquidated Damages, if any, with respect to the Notes to
violate this Article Eleven. Only the Company or a Representative may give the
notice. Nothing in this Article Eleven shall impair the claims of, or payments
to, the Trustee under or pursuant to Section 7.07 hereof.

                                     109

<PAGE>

                  The Trustee in its individual or any other capacity may hold
Senior Indebtedness with the same rights it would have if it were not Trustee.
Any Agent may do the same with like rights.

SECTION 11.12.        AUTHORIZATION TO EFFECT SUBORDINATION.

                  Each Holder of a Note by the Holder's acceptance thereof
authorizes and directs the Trustee on the Holder's behalf to take such action
as may be necessary or appropriate to effectuate the subordination as provided
in this Article Eleven, and appoints the Trustee to act as the Holder's
attorney-in-fact for any and all such purposes. If the Trustee does not file a
proper proof of claim or proof of debt in the form required in any proceeding
referred to in Section 6.09 hereof at least 30 days before the expiration of
the time to file such claim, a Representative of Designated Senior Indebtedness
is hereby authorized to file an appropriate claim for and on behalf of the
Holders of the Notes and the Trustee shall have no liability therefor.

SECTION 11.13.        TRUST MONEYS NOT SUBORDINATED.

                  Notwithstanding anything contained herein to the contrary,
payments from cash or the proceeds of U.S. Government Securities held in the
Interest Reserve Account and in trust under Article Eight hereof by the Trustee
(or other qualifying trustee) and which were deposited in accordance with the
terms of the Escrow Agreement and Article Eight hereof, respectively, and not
in violation of Section 11.03 hereof for the payment of principal of (and
premium, if any) and interest on the Notes shall not be subordinated to the
prior payment of any Senior Indebtedness or subject to the restrictions set
forth in this Article Eleven, and none of the Holders shall be obligated to pay
over any such amount to the Company or any holder of Senior Indebtedness or any
other creditor of the Company.

SECTION 11.14.        PAYMENT AND DISTRIBUTION.

                  For purposes of this Article Eleven, the term "payment"
and/or "distribution" means any payment or distribution (whether direct or
indirect, whether in cash, property, securities, or otherwise, and whether
obtained or distributed by set-off, liquidation, bankruptcy distribution,
settlement, or otherwise) made by any Person (including, without limitation,
any payments or distributions made pursuant to Section 4.16(f) or by any court
or governmental body or agency, any trustee in bankruptcy, or any liquidating
trustee) with respect to any Note or any Guarantee of the Notes or otherwise
under this Indenture, including, without limitation, payment of principal,
premium, interest, or Liquidated Damages, if any, on the Notes or any payments
under or with respect to any Guarantee of the Notes, any depositing of funds
with the Trustee or any Paying Agent (including, without limitation, a deposit
in respect of defeasance or redemption, but expressly excluding the Internet
Reserve Account), any payment on account of any optional or mandatory
redemptions or repurchase provisions, any payment or recovery on any claim
under the Indenture, any Guarantee of the Notes, any Note, or

                                      110
<PAGE>

relating to or arising out of the offer, sale, or purchase of any Note (whether
for rescission or damages and whether based on contract, tort, duty imposed by
law, or any other theory of liability); provided that, for the purposes of this
Article Eleven, all Obligations now or hereafter existing under any Senior
Indebtedness, (including, without limitation, the Senior Credit Facility, any
Interest Rate Protection Agreements, Currency Agreements, or agreements with
respect to the issuance of letters of credit) shall not be deemed to have been
paid in full unless the holders thereof shall have received payment in full and
all commitments thereunder and all letters of credit issued thereunder have
expired.

SECTION 11.15.        NO CLAIMS.

                  No holder of the Subordinated Indebtedness shall have any
claim to any property or assets of the Company, any Guarantor, or any
Subsidiary of the Company or any Guarantor, unless and until the Senior
Indebtedness shall have been fully paid and satisfied; except with respect to
the Lien on the Pledged Securities in the Interest Reserve Account.

SECTION 11.16.        ACKNOWLEDGEMENT OF HOLDERS.

                  Each holder of Subordinated Indebtedness by accepting a Note
or Guarantee of the Notes acknowledges and agrees that the foregoing
subordination provisions are, and are intended to be, an inducement and
consideration to each holder of Senior Indebtedness, whether such Senior
Indebtedness was created or acquired before or after the issuance of the Notes
or the Guarantees of the Notes, to acquire and continue to hold, or to continue
to hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall
be deemed conclusively to have relied on such subordination provisions in
acquiring and continuing to hold, or in continuing to hold, such Senior
Indebtedness.

taken in reliance upon such waiver.

upon any obligation, covenant or agreement of the Company contained in this
Indenture or in any of the Notes, or because of the creation of any Indebtedness
represented thereby, shall be had against any incorporator or past, present or
future director, officer, employee, controlling Person or stockholder of the
Company. Each Holder by accepting a Note waives and releases all such liability.
The waiver and release are part of the consideration for issuance of the Notes.
Such waiver may not be effective to waive liabilities under the federal
securities laws and it is the view of the Commission that such a waiver is
against public policy.

                  Capitalized terms used herein shall have the meanings assigned

next succeeding Interest Payment Date; PROVIDED, FURTHER, that the first
Interest Payment Date shall be October 15, 2001. The Company shall pay interest
(including post-petition interest in any proceeding under any Bankruptcy Law)
on overdue principal and premium, if any, from time to time on demand at a rate
that is 1% per annum in excess of the rate then in effect; it shall pay
interest (including post-petition interest in any, proceeding under any
Bankruptcy Law) on overdue installments of interest and Liquidated Damages, if
any (without regard to any applicable grace periods) from time to time on
demand at the same rate to the extent lawful. Interest shall be computed on the
basis of a 360-day year of twelve 30-day months.

                  2. METHOD OF PAYMENT. The Company shall pay principal,
premium, if any, interest and Liquidated Damages, if any, on the Notes to the
Persons who are registered Holders of Notes at the close of business on the
April 1 or October 1 next preceding the interest payment date, even if such
Notes are cancelled after such record date and on or before such interest
payment date, except as provided in Section 2.12 of the Indenture with respect
to defaulted interest. The Notes shall be payable by wire transfer of
immediately available funds to the registered Holder of the relevant Global
Note and, with respect to certificated Notes, by wire transfer of immediately
available funds in accordance with instructions provided by the registered
Holders of certificated Notes or, if no such instructions are specified, by
mailing a check to each such Holder's registered address. Such payment shall be
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts.

                  3. PAYING AGENT AND REGISTRAR. Initially, United States Trust
Company of New York, the Trustee under the Indenture, shall act as Paying Agent
and Registrar. The Company may change any Paying Agent or Registrar without
notice to any Holder. The Company or any of its Subsidiaries may act in any
such capacity.

                  4. INDENTURE. The Company issued the Notes under an Indenture
dated as of March 14, 2001 ("Indenture") between the Company, the Guarantors
named therein and the Trustee. The terms of the Notes include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb). The
Notes are subject to all such terms, and Holders are referred to the Indenture
and such Act for a statement of such terms. To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling.

                  5. OPTIONAL REDEMPTION

                  (a) At any time prior to October 15, 2005, the Notes may be

be permitted to redeem up to 35% of the aggregate principal amount of the Notes

thereof are contributed to the Company; PROVIDED, HOWEVER, that (1) at least 65%
of the aggregate principal amount of the Notes issued on the Issue Date remains
outstanding immediately after the occurrence of the redemption; and (2) each
redemption occurs within 180 days after the date of the closing of such Equity
Offering.

                  6. MANDATORY REDEMPTION.

payments with respect to the Notes.

                  7. REPURCHASE AT OPTION OF HOLDER.

                  (a) If there is a Change of Control, the Company shall be

part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at
a purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and unpaid interest and Liquidated Damages, thereon, if any, to the date

Change of Control, the Company shall mail a notice to each Holder setting forth
the procedures governing the Change of Control Offer as required by the
Indenture.

Proceeds so received exceed 10% of Adjusted Consolidated Net Tangible Assets,
to (i) apply an amount equal to such excess Net Cash Proceeds to permanently
repay Senior Indebtedness of the Company or Senior Indebtedness of any
Restricted Subsidiary in each case owing to a Person other than the Parent
Guarantor or any Restricted Subsidiaries, or (ii) invest an equal amount, or
the amount not so applied pursuant to clause (i) (or enter into a definitive
agreement committing to so invest within 12 months after the date of such
agreement), in property or assets (other than current assets) of a nature or
type or that are used in a business (or in a company having property and assets
of a nature or type, or engaged in a business) related, ancillary or

existing on the date of such Investment, and (b) apply, no later than the end
of the 12-month period referred to in clause (a) above, such excess Net Cash
Proceeds (to the extent not applied pursuant to clause (a)), as provided below.
The amount of such excess Net Cash Proceeds required to be applied, or to be
committed to be applied, during such twelve-month period as set forth in clause
(a) and not applied as so required by the end of such period shall constitute
"Excess Proceeds."

                  If, as of the first day of any calendar month, the aggregate
amount of Excess Proceeds not theretofore subject to an Offer to Purchase totals
at least $10.0 million, the Company must commence, not later than the fifteenth
Business Day of such month, and consummate an Offer to Purchase from the Holders
of Notes and the Holders of any Indebtedness ranking equally with the Notes and
entitled to participate in such an Offer to Purchase on a pro rata basis, an
aggregate principal amount of Notes and such other Indebtedness equal to the
Excess Proceeds on such date, at a purchase price equal to 101% of the principal
amount thereof, plus, in each case, accrued interest and Liquidated Damages, if
any, to the Payment Date.

                  8. 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 whose Notes are to be redeemed at its registered address. Notes and
portions of Notes selected shall be in amounts of $1,000 or whole multiples of
$1,000; except that if all of the Notes of a Holder are to be redeemed, the
entire outstanding amount of Notes held by such Holder, even if not a multiple
of $1,000, shall be redeemed. On and after the redemption date interest ceases
to accrue on Notes, or portions thereof called for redemption.

                  9. SUBORDINATION. The Notes are subordinated to Senior
Indebtedness, as defined in the Indenture. To the extent provided in the
Indenture, Senior Indebtedness must be paid in full before the Notes may be
paid. The Company and each Guarantor agrees, and each Holder by accepting a Note
agrees, to the subordination provisions contained in the Indenture and
authorizes the Trustee to give it effect and appoints the Trustee as
attorney-in-fact for such purpose.

transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company need not
exchange or register the transfer of any Note or portion of a Note selected for
redemption, except for the unredeemed portion of any Note being redeemed in
part. Also, the Company need not exchange or register the transfer of any Notes
for a period of 15 days before a selection of Notes to be redeemed or during the
period between a record date and the corresponding interest payment date.

                  11. PERSONS DEEMED OWNERS. The registered Holder of a Note may
be treated as its owner for all purposes.

                  12. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain
exceptions, the Indenture or the Notes may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the then
outstanding Notes voting as a single class, and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes voting as a single class. The consent of the Holders of at
least two-thirds in principal amount of the then outstanding Notes voting as a
single class is required to modify the provisions of the Indenture relating to
subordination and the Guarantees, in each case so as to adversely affect the
rights of any Holder. Without the consent of any Holder of a Note, the Indenture
or the Notes may be amended or supplemented to cure any ambiguity, defect or
inconsistency, to provide for uncertificated Notes in addition to or in place of
certificated Notes, to provide for the assumption of the Company's obligations
to Holders of the Notes in case of a merger or consolidation, or sale of
substantially all of the Company's assets, to make any change that would provide
any additional rights or benefits to the Holders of the Notes or that does not
adversely affect the legal rights under the Indenture of any such Holder, or to
comply with the requirements of the Commission in order to effect or maintain
the qualification of the Indenture under the Trust Indenture Act.

                  13. DEFAULTS AND REMEDIES. Events of Default include, in

or Liquidated Damages, if any, on the Notes; (c) default in the performance of
the provisions of Sections 5.01 of the Indenture; (d) default in the performance
of the Escrow Agreement; (e) default for 30 days after notice in the performance
of Section 4.03, 4.07, 4.08, 4.09, 4.10, 4.12, 4.13, 4.14, 4.16, 4.17 and 4.18
of the Indenture; (f) failure by the Company or any Restricted Subsidiaries for
60 days after notice to comply with any of its other agreements in the Indenture
or the Notes; (g) the nonpayment within any applicable grace period after the
final maturity, or the acceleration by the Holders because of a default, of
Indebtedness of the Parent Guarantor, the Company or any Significant Subsidiary,
and

                                      A-8
<PAGE>

the total amount of such Indebtedness unpaid or accelerated exceeds $20.0
million; (h) failure by the Company or any of its Significant Subsidiaries to
pay final judgments aggregating in excess of $20.0 million, which judgments are
not paid, discharged or stayed for a period of 30 consecutive days; and (g)
certain events of bankruptcy or insolvency with respect to the Parent
Guarantor, the Company or any of its Significant Subsidiaries. If any Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in
principal amount of the then outstanding Notes may declare all the Notes to be
due and payable, subject to certain conditions. Notwithstanding the foregoing,
in the case of an Event of Default arising from certain events of bankruptcy or
insolvency, all outstanding Notes shall become due and payable without further
action or notice. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a
majority in aggregate principal amount of the then outstanding Notes may direct
the Trustee in its exercise of any trust or power. The Trustee may withhold
from Holders of the Notes notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal or
interest) if it determines that withholding notice is in their interest. The
Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest and premium, if any, on, or the principal of, the Notes. The Company
is required to deliver to the Trustee annually a statement regarding compliance
with the Indenture, and the Company is required upon becoming aware of any
Default or Event of Default, to deliver to the Trustee a statement specifying
such Default or Event of Default.

                  14. DEFEASANCE. The Indenture and the obligations under the
Notes may be defeased (subject to certain exceptions) or the Company may cease
to comply with certain covenants of the Indenture, upon satisfaction of the
conditions specified in Article 8 of the Indenture.

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

                  16. NO RECOURSE AGAINST OTHERS. No recourse for the payment of
the principal of, premium, if any, or interest or Liquidated Damages, if any, on
any of the Notes, or for any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company contained in this Indenture or in any of the Notes, or because of
the creation of any Indebtedness represented thereby, shall be had against any
incorporator or past, present or future director, officer, employee, controlling
Person or stockholder of the Company. Each Holder by accepting a Note waives and
releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes.

any Guarantee, Indenture, any supplemental indenture delivered pursuant to the
Indenture by such Guarantor or any Guarantees of the Notes, or for any claim
based on, in respect of or by reason of such obligations or their creation. Each

attorney-in-fact for such purpose.

         shall forthwith become due and payable by the Guarantors for the
         purpose of this Guarantee.

                  (viii) The Guarantors shall have the right to seek
         contribution from non-paying Guarantor so long as the exercise of such
         right does not impair the rights of the Holders under the Guarantee.

                  (ix)   Notwithstanding the foregoing, in the event that this
         Guarantee would constitute or result in a violation of any applicable
         fraudulent conveyance or similar law of any relevant jurisdiction, the
         liability of the Guarantor under this Supplemental Indenture and its
         Guarantee of the Notes shall be reduced to the maximum amount
         permissible under such fraudulent conveyance or similar law.

                  (x)    Notwithstanding anything herein to the contrary, all
         obligations of the Guarantor hereunder shall be subordinated to the
         prior payment of Senior Indebtedness to the same extent that the Notes
         are subordinated pursuant to Article 11 of the Indenture.

                    (c) EXECUTION AND DELIVERY. Each Subsidiary Guarantor agrees
that the Guarantees shall remain in full force and effect notwithstanding any
failure to endorse on each Note a notation of such Guarantee of the Notes.

                    (d) GUARANTOR MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.

                  (i)   Subject to Section 5 hereof, the Guarantor may not
         consolidate with or merge with or into (whether or not such Guarantor
         is the surviving Person) another corporation, Person or entity whether
         or not affiliated with such Guarantor unless:

                           (A) subject to Section 5 hereof, the Person formed by
                  or surviving any such consolidation or merger (if other than a
                  Guarantor or the Company) unconditionally assumes all the
                  obligations of such Guarantor, pursuant to a supplemental
                  indenture in form and substance reasonably satisfactory to the
                  Trustee, under the Notes, the Indenture and the Guarantee of
                  the Notes on the terms set forth herein or therein; and

                                      F-3
<PAGE>

                           (B) immediately after giving effect to such
                  transaction, no Default or Event of Default exists.

                  (ii)  In case of any such consolidation, merger, sale or
         conveyance and upon the assumption by the Successor Person, by
         supplemental indenture, executed and delivered to the Trustee and
         satisfactory in form to the Trustee, of the Guarantee endorsed upon the
         Notes and the due and punctual performance of all of the covenants and
         conditions of the Indenture to be performed by the Guarantor, such
         Successor Person shall succeed to and be substituted for the Guarantor
         with the same effect as if it had been named herein as a Guarantor.
         Such Successor Person thereupon may cause to be signed any or all of
         the Guarantees to be endorsed upon all of the Notes issuable hereunder
         which theretofore shall not have been signed by the Company and
         delivered to the Trustee. All the Guarantees of the Notes so issued
         shall in all respects have the same legal rank and benefit under the
         Indenture as the Guarantees of the Notes theretofore and thereafter
         issued in accordance with the terms of the Indenture as though all of
         such Guarantees of the Notes had been issued at the date of the
         execution hereof.

                  (iii) Except as set forth in Articles 4 and 5 of the
         Indenture, and notwithstanding clauses (i) and (ii) of Section 4(a)
         hereof, nothing contained in the Indenture or in any of the Notes shall
         prevent any consolidation or merger of a Subsidiary Guarantor with or
         into the Company or another Subsidiary Guarantor, or shall prevent any
         sale or conveyance of the property of a Subsidiary Guarantor as an
         entirety or substantially as an entirety to the Company or another
         Subsidiary Guarantor.

                    (e) RELEASES.

                  (i)   In the event of a sale or other disposition of all of
         the assets of any Guarantor, by way of merger, consolidation or
         otherwise, or a sale or other disposition of all to the capital stock
         of any Guarantor, then such Guarantor (in the event of a sale or other
         disposition, by way of merger, consolidation or otherwise, of all of
         the capital stock of such Guarantor) or the corporation acquiring the
         property (in the event of a sale or other disposition of all or
         substantially all of the assets of such Guarantor) shall be released
         and relieved of any obligations under the Supplemental Indenture and
         its Guarantee of the Notes; PROVIDED that the Net Proceeds of such
         sale or other disposition are applied in accordance with the
         applicable provisions of the Indenture, including without limitation
         Section 4.11 of the Indenture. Upon delivery by the Company to the
         Trustee of an Officers' Certificate and an Opinion of Counsel
         complying with Sections 13.04 and 13.05 to the effect that such sale
         or other disposition was made by the Company in accordance with the
         provisions of the Indenture, including without limitation Section 4.11
         of the Indenture, the Trustee shall execute any

                                      F-4
<PAGE>

         documents reasonably required in order to evidence the release of any
         Guarantor from its obligations under its Guarantee of the Notes.

                  (ii)  Any Guarantor not released from its obligations under
         its Guarantee shall remain liable for the full amount of principal of
         and interest on the Notes and for the other obligations of any
         Guarantor under the Indenture as provided in the Indenture.

                    (f) SUBORDINATION. The Notes and Guarantees of the Notes are
subordinated to Senior Indebtedness, as defined in the Indenture. Pursuant to
Article Eleven of the Indenture, Senior Indebtedness must be paid in full before
the Notes may be paid. Each Guarantor agrees, and each Holder by accepting a
Note agrees, to the subordination provisions contained in the Indenture and
authorizes the Trustee to give it effect and appoints the Trustee as
attorney-in-fact for such purpose.

                    (g) NO RECOURSE AGAINST OTHERS. No past, present or future
director, officer, employee, incorporator, stockholder or agent of the
Guarantor, as such, shall have any liability for any obligations of the Company
or any Guarantor under the Notes, any Guarantees of the Notes, the Indenture or
this Supplemental Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder of Notes by accepting
a Note waives and releases all such liability. The waiver and release are part
of the consideration for issuance of the Notes. Such waiver may not be effective
to waive liabilities under the federal securities laws and it is the view of the
Commission that such a waiver is against public policy.

                    (h) NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF
NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT
WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT
THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED
THEREBY.

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

                    (j) EFFECT OF HEADINGS. The Section headings herein are for
convenience only and shall not affect the construction hereof.

                    (k) THE TRUSTEE. The Trustee shall not be responsible in any
manner whatsoever for or in respect of the validity or sufficiency of this
Supplemental Indenture or for or in respect of the recitals contained herein,
all of which recitals are made solely by the Guarantor and the Company.
