EMPLOYMENT AGREEMENT

     This
EMPLOYMENT AGREEMENT (the “Agreement”) is made as of this
          day of,
by and between Intersections Inc., a Delaware corporation, with offices at 14901
Bogle Street, Chantilly, Virginia 20151 (the “Corporation”) and George K. Tsantes,
an individual, residing at 650 Nalls Farm Way, Great Falls, Virginia 22066 (the
“Executive”).

 W I T N E S S E T H :

     WHEREAS, the Corporation desires to employ the Executive and the Executive
desires to accept such continued employment upon the terms and conditions contained
in this Agreement;

     NOW, THEREFORE, for and in consideration of the premises and the mutual
covenants and agreements herein contained, and for other valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereby
agree as follows:

     1. Employment. The Corporation hereby employs the Executive, and the
Executive hereby accepts employment, as the Chief Technology Officer of the
Corporation under the terms and conditions set forth herein. The
Corporation’s obligations under this Agreement are conditioned upon negative
drug test results, satisfactory background screening results,
and verification of eligibility to work in the United States in accordance
with the Immigration Reform and Control Act of 1986, in each case in
accordance with standard Corporation policy. The Executive acknowledges and
agrees that commencement of his employment prior to satisfaction of one or
more of the foregoing conditions does not waive the Corporation’s right
to terminate his employment immediately based on failure to satisfy one or
more of those conditions.

     2. Term. This Agreement and the Executive’s employment commence on
January         , 2005, and are for an indefinite term. Therefore, the Executive is employed on an at-will basis and either the Executive or the Corporation may terminate his employment
at any time and for any reason, with or without “cause” including, without
limitation, as defined in paragraph 6.c.; provided, however, other than in
the case of termination by the Corporation for “cause” as defined in paragraph 6.c.
or due to the Executive’s death as set forth in paragraph 6.a., both the
Corporation and the Executive shall give the other 60 days’ prior written notice of
termination. Notwithstanding the foregoing, the Corporation may, at its option,
provide up to 60 days’ full pay and benefits in lieu of such 60 days’ notice or any
portion thereof.

     3. Duties.

          a. While the Executive is employed pursuant to this Agreement, he
shall perform such duties and discharge such responsibilities as the Board of
Directors of the Corporation shall from time to time direct, which duties and
responsibilities shall be commensurate with the Executive’s position. The
Executive shall comply fully with all

 

 

applicable laws, rules and regulations as well as with the Corporation’s policies and procedures.
The Executive shall devote his entire working time to the business of the Corporation and shall use
his best efforts, skills and abilities in his diligent and faithful performance of his duties and
responsibilities hereunder. While the Executive is employed pursuant to this Agreement, he shall
not engage in any other business activities or hold any office or position, regardless of whether
any such activity, office or position is pursued for profit or other pecuniary advantage, without
the prior written consent of the Corporation; provided, however, the Executive may engage
in (i) personal investment activities for himself and his family and (ii) charitable and civic
activities, so long as such outside interests set forth in subsections (i) and (ii) hereof do not
interfere with the performance of his duties and responsibilities hereunder.

          b. The Board of Directors of the Corporation reserves the right from time to time to
assign to the Executive additional duties and responsibilities and to delegate to other employees
of the Corporation duties and responsibilities normally discharged by the Executive. All such
assignments and delegations of duties and responsibilities shall be made in good faith and shall
not materially affect the general character of the work to be performed by the Executive. The
Executive shall hold such officerships and directorships in the Corporation and any subsidiary to
which, from time to time, the Executive may be appointed or elected.

     4. Compensation and Related Matters. As full compensation for the Executive’s
performance of his duties and responsibilities during his employment pursuant to this Agreement,
the Corporation shall pay the Executive the compensation and provide the benefits set forth below:

          a. Base Salary. The Corporation shall pay the Executive an annual salary (the
“Base Salary”) of $265,000.00 less applicable withholding and other deductions, payable
in accordance with the Corporation’s then current payroll practices. The Base Salary will
be reviewed at least annually by the Corporation’s Board of Directors and may be increased,
but not decreased, in its sole discretion, in which event any increased Base Salary shall be
deemed the Base Salary under this Agreement.

          b. Bonus. The Executive shall be entitled to participate in any bonus (each
a “Bonus”) plan adopted by the Corporation, or any subsidiary, which may be in effect at any
time during the Executive’s employment by the Corporation, including, without limitation, any
bonus plan adopted for officers, or for senior or executive officers, of the Corporation. The
Executive’s participation in any Bonus plan shall be subject to the plan conditions adopted
by the Board of Directors or its Compensation Committee.

          c. Benefits.

               (i) The Executive shall be entitled to participate in, and receive
benefits from, any insurance, medical, dental, disability, incentive compensation, stock option or
other employee benefit plan, if any are adopted, of the Corporation or any subsidiary which may be
in effect at any time during the Executive’s employment by the Corporation.

               (ii) In addition to the benefits provided under paragraph 4.c(i) above, the Corporation
shall pay for any medical or dental costs incurred by the Executive, or his

- 2 -

 

dependents covered by the Corporation’s group medical and dental insurance, to the extent not paid
by the Corporation’s group medical or dental insurance, including, without limitation, deductibles,
provided such payment in any calendar year does not exceed an amount equal to 5% of the Executive’s
Base Salary in that calendar year. In addition, the Corporation shall pay for one comprehensive
physical examination of the Executive in each calendar year, together with such diagnostic or other
tests that are part of such examination. The Corporation may provide the benefits under this
paragraph 4.c(ii) either by purchasing additional insurance or by making direct payments to the
Executive or his medical provider, as determined by the Corporation in its sole discretion. As a
condition of payment, the Executive must submit bills or other documents satisfactory to the
Corporation or its insurance provider.

          d. Leave. The Executive shall be eligible to receive and take paid leave
that the Corporation generally makes available to its senior officers in accordance with
the Corporation’s leave policies (as may be revised from time to time).

          e. Car Allowance. The Corporation shall provide the Executive with an annual car
allowance (the “Car Allowance”), which shall be applied to the purchase or lease of
a vehicle. The Car Allowance shall equal 4% of the Executive’s Base Salary, less
applicable withholding and other deductions, and shall be divided into equal payments and
paid on the same basis as the Corporation’s payroll. The Executive shall be responsible for
the maintenance and operation of the vehicle and the costs associated with the same,
including, without limitation, insurance.

     5. Expenses. The Corporation or its subsidiaries shall reimburse the Executive
for expenses which the Executive may from time to time reasonably incur on behalf of and at
the request of the Corporation in the performance of his responsibilities and duties under
this Agreement, provided that the Executive shall be required to account to the Corporation
for such expenses in the manner prescribed by the Corporation.

     6. Termination. This Agreement and the Executive’s employment shall terminate:

          a. immediately upon the Executive’s death; or

          b. upon the Executive being unable to perform his duties and responsibilities hereunder
due to his disability (as defined below). For purposes of this Agreement, the
term “disability” shall mean that the Executive has been unable to perform the duties
and responsibilities required of him hereunder due to a physical and/or mental condition for
a period of 90 consecutive days or 180 non-consecutive days during any 12-month period.
During such period of disability, the Executive shall continue to receive the Base Salary
(less any Corporation-paid benefits that he receives, such as short term disability or
workers compensation, during such period); or

          c. upon the existence of cause. For purposes of this Agreement, “cause” shall mean that
the Executive: (i) has been convicted of, or entered a plea of nolo contendre to,
a misdemeanor involving moral turpitude or any felony under the laws of the United States or
any state or political subdivision thereof; (ii) has committed an act constituting a breach
of fiduciary duty, fraud, gross negligence or willful misconduct; (iii) has engaged in
conduct that violated the

- 3 -

 

Corporation’s then existing internal policies or procedures and which is materially detrimental to
the business, reputation, character or standing of the Corporation or any of its subsidiaries; or
(iv) after written notice to the Executive and a reasonable opportunity of at least 30 days to
cure, the Executive shall continue (x) to be in material breach of the terms of this Agreement; (y)
to fail or refuse to attend to the material duties and responsibilities assigned to him by the
Corporation’s Board of Directors hereunder; or (z) to be absent excessively for reasons unrelated
to disability; or

          d. upon the existence of “good reason”. For purposes of this Agreement, the following
shall constitute “good reason”: Upon written notice setting forth the alleged good reason by
Executive to the Corporation, and the expiration of a 30-day cure period, there continues to
be: (i) a reduction in the Executive’s Base Salary and/or in the aggregate benefits provided
for hereunder; (ii) the relocation of the Executive’s office to a location outside of a
30-mile radius from the Corporation’s present Chantilly, Virginia location; (iii) a material
breach by the Corporation of the terms of this Agreement; or (iv) the failure by the
Corporation to obtain an agreement from any successor to the Corporation to assure that such
successor guarantees the Corporation’s performance of this Agreement or assumes and
undertakes to perform the Corporation’s obligations hereunder; provided, however, in
the event of a “change in control” as defined in paragraph 6.e. hereof, then the Corporation
shall cease to have a 30-day period within which to cure the alleged good reason.

          e. for the purposes of this Agreement, the term “change in control” shall mean
that:

               (i) any “person or “group” (as such terms are used in Sections 13(d) and 14(d) of the
Securities Exchange Act of 1934, as amended (the “Exchange Act”), other than the Corporation, any
existing director or officer of the Corporation, any trustee or other fiduciary holding securities
under an employee benefit plan of the Corporation, or any corporation owned, directly or
indirectly, by the stockholders of the Corporation in substantially the same proportions as their
ownership of stock of the Corporation, becomes the “beneficial owner” (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities of the Corporation representing 30%
or more of the Common Stock of the Corporation; or

               (ii) the stockholders of the Corporation approve a merger or
consolidation of the Corporation with any other corporation, other than a merger or
consolidation which would result in the voting securities of the Corporation outstanding
immediately prior thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving entity) more than 50% of the combined voting
power of the voting securities of the Corporation or such surviving entity outstanding immediately
after such merger or consolidation; or

               (iii) the stockholders of the Corporation approve an agreement for the sale or
disposition by the Corporation of all or substantially all of the Corporation’s assets.

          f. If the Executive’s employment is terminated by: (a) the Corporation pursuant to
paragraph 6.a., b. or c., or (b) the Executive other than pursuant to paragraph 6.d., then,
unless the parties otherwise mutually agree, in full satisfaction of the Corporation’s

- 4 -

 

obligations under this Agreement the Executive, his beneficiaries or estate, as appropriate, shall
be entitled to receive (i) the Base Salary provided for herein up to and including the effective
date of termination, prorated on a daily basis; provided, however, in the event of
termination due to the Executive’s death or disability as provided in paragraph 6.a. and b.,
respectively, then his Base Salary shall continue to be paid up to the end of the month in which
the death or termination due to disability occurs; (ii) any Bonus due at the time of termination
under a then current Bonus plan; (iii) medical benefit continuation at the Executive’s and/or his
dependent’s expense as provided by law; provided, however, in the event of termination due
to the Executive’s death or disability as provided in paragraph 6.a. and b., respectively, then the
Corporation will pay the cost of the Executive’s medical benefit continuation for Executive and any
covered dependents for up to 18 months or until the Executive and/or his covered dependents are
covered by another company’s group health insurance, whichever is sooner; and (v) benefits, if any,
payable upon the Executive’s death or disability, respectively.

          g. If the Executive’s employment is terminated by: (a) the Corporation other than
pursuant to paragraph 6.a., b. or c. or (b) the Executive pursuant to paragraph 6.d., then, unless
the parties otherwise mutually agree, in full satisfaction of the Corporation’s obligations under
this Agreement the Executive, his beneficiaries or estate, as appropriate, shall be entitled to
receive: (i) the Base Salary provided for herein up to and including the effective date of
termination, prorated on a daily basis; (ii) any Bonus due at the time of termination under a then
current Bonus plan; (iii) severance in an amount equal to the total cash compensation (Base Salary
and Bonus) that the Executive has received (whether or not pursuant to this Agreement) during the
prior 18-month period, or the prior 30-month period if the Executive’s employment is terminated
twelve months or less after a change in control in exchange for a general release in form and
content satisfactory to the Corporation to be paid in one payment upon such release becoming
effective; and (iv) medical benefit continuation at the Executive’s and/or his dependent’s expense
as provided by law; provided, however, as additional consideration for the general release
set forth in paragraph 6.g. (iii), the Corporation will pay the cost of the Executive’s medical
benefit continuation pursuant to paragraphs 4.c(i) and 4.c(ii) for the Executive and any covered
dependents for up to 18 months or until the Executive and/or his covered dependents are covered by
another company’s group health insurance, whichever is sooner. In the event the Executive has been
employed by the Corporation for less than 18 months at the time of termination under this
paragraph, or 30 months if the Executive’s employment was terminated twelve months or less after a
change in control, the amount of the severance under this paragraph 6.g shall be computed as
follows, with “X” representing the amount of severance:

Actual Total Cash
Compensation (Base Salary and Bonus) = X

                          Number of Days
Employed                            Y

The denominator “Y” in the equation above equals 540, or 900 if the Executive’s employment was
terminated twelve months or less after a change in control. This means, for example, if the
Executive’s Total Cash Compensation were $150,000 and he worked for the Corporation for 270 days,
then “X” would equal, and he would receive severance in the amount of, $300,000, or $500,000 if the
Executive’s employment was terminated twelve months or less after a change in control.

          h. The Executive hereby acknowledges that he is employed by the
Corporation for an indefinite term and nothing in this Agreement, including, without limitation,
this paragraph 6, changes the at-will nature of his employment.

	 	7.  	Confidential and Proprietary Information; Work Product;
Warranty;
 Non-Competition; Non-Solicitation.

          a. Confidentiality. The Executive acknowledges and agrees that there are certain
trade secrets and confidential and proprietary information (collectively,
“Confidential Information”) which have been developed by the Corporation and which are used
by the Corporation in its business. Confidential Information shall include, without
limitation: (i) customer lists and supplier lists; (ii) the details of the Corporation’s
relationships with its customers, including, without limitation, the financial relationship
with a customer, knowledge of the internal “politics” workings of a customer organization, a
customer’s technical needs and job specifications, knowledge of a customer’s strategic plans
and the identities of contact persons within a customer’s organization; (iii) the
Corporation’s marketing and development plans, business plans; and (iv) other information
proprietary to the Corporation’s business. The Executive shall not, at any time during or
after his employment hereunder, use or disclose such Confidential Information, except to
authorized representatives of the Corporation or the customer or as required in the
performance of his duties and responsibilities hereunder. The Executive shall return all
customer and/or Corporation property, such as computers, software and cell phones, and
documents (and any copies including, without limitation, in machine or human- readable form),
to the Corporation when his employment terminates. The Executive shall not be required to
keep confidential any information, which (x) is or becomes publicly available through no
fault of the Executive or (y) is already in his possession (unless obtained from
the Corporation or one of its customers). Further, the Executive shall be free to use and
employ his general skills, know-how and expertise, and to use, disclose and employ any
generalized ideas, concepts, know-how, methods, techniques or skills, including, without
limitation, those gained or learned during the course of the performance of his duties and
responsibilities hereunder, so long as he applies such information without disclosure or use
of any Confidential Information.

          b. Work Product. The Executive agrees that all copyrights, patents,
trade secrets or other intellectual property rights associated with any ideas, concepts,
techniques, inventions, processes, or works of authorship developed or created by him during
his employment by the Corporation and for a period of 6 months thereafter, that (i) relate,
whether directly or indirectly, to the Corporation’s actual or anticipated business, research
or development or (ii) are suggested by or as a result of any work performed by the Executive
on the Corporation’s behalf, shall, to the extent possible, be considered works made for hire
within the meaning of the Copyright Act (17 U.S.C. § 101 et. seq.) (the “Work Product”). All
Work Product shall be and remain the property of the Corporation. To the extent that any such
Work Product may not, under applicable law, be considered works made for hire, the Executive
hereby grants, transfers, assigns, conveys and relinquishes, and agrees to grant, transfer,
assign, convey and relinquish from time to time, on an exclusive basis, all of his right,
title and interest in and to the Work Product to the Corporation in perpetuity or for the
longest period otherwise permitted by law. Consistent with his recognition of the
Corporation’s absolute ownership of all Work Product, the Executive agrees that he shall (i)
not use any Work Product for the benefit of any party other than the Corporation and (ii)
perform such acts and execute such documents and

- 6 -

 

instruments as the Corporation may now or hereafter deem reasonably necessary or desirable to
evidence the transfer of absolute ownership of all Work Product to the Corporation; provided,
however, if following 10 days’ written notice from the Corporation, the Executive refuses, or
is unable, due to disability, incapacity, or death, to execute such documents relating to the Work
Product, he hereby appoints any of the Corporation’s officers as his attorney-in-fact to execute
such documents on his behalf. This agency is coupled with an interest and is irrevocable without
the Corporation’s prior written consent.

          c. Warranty. The Executive represents and warrants to the Corporation that (i)
there are no claims that would adversely affect his ability to assign all right, title and
interest in and to the Work Product to the Corporation; (ii) the Work Product does not
violate any patent, copyright or other proprietary right of any third party; (iii) the
Executive has the legal right to grant the Corporation the assignment of his interest in the
Work Product as set forth in this Agreement; and (iv) he has not brought and will not bring
to his employment hereunder, or use in connection with such employment, any trade secret,
confidential or proprietary information, or computer software, except for software that he
has a right to use for the purpose for which it shall be used, in his employment hereunder.

          d. Non-Competition; Non Solicitation. The Executive agrees that during
his employment by the Corporation and for 18 months thereafter, regardless of the
circumstances which result in his termination, he shall not within the continental United
States (i) engage or attempt to engage, directly or indirectly, whether as an employee,
officer, director, consultant or otherwise, in any business activity which is the same as,
substantially similar to or directly competitive with the Corporation; (ii) solicit or
attempt to solicit, directly or indirectly, whether as an employee, officer, director,
consultant or otherwise, any person or entity which is then a customer of the Corporation or
has been a customer or solicited by the Corporation in the preceding 18-month period, to
purchase products or services directly competitive with those sold or provided by the
Corporation from any entity other than the Corporation; (iii) solicit for employment, engage
and/or hire, whether directly or indirectly, any individual who is then employed by the
Corporation or engaged by the Corporation as an independent subcontractor or consultant;
and/or (iv) encourage or induce, whether directly or indirectly, any individual who is then
employed by the Corporation or engaged by the Corporation as an independent contractor
or consultant to end his/her business relationship with the Corporation; provided,
however, nothing in this paragraph 7.d. shall prevent the Executive from owning, solely
as an investment, up to 5% of the securities of any publicly-traded company.

          e. Cooperation. The Executive agrees, upon reasonable notice, to cooperate fully
with the Corporation and its legal counsel on any matters relating to the conduct of
any litigation, claim, suit, investigation or proceeding involving the Corporation in
connection with any facts or circumstances occurring during the Executive’s employment with
the Corporation in which the Corporation reasonably determines that the Executive’s
cooperation is necessary or appropriate.

          f. Injunctive Relief; Remedy. The Executive acknowledges that a breach
or threatened breach of any of the terms set forth in this paragraph 7 shall result in an
irreparable and continuing harm to the Corporation for which there shall be no adequate
remedy at law. The Corporation shall, without posting a bond, be entitled to seek injunctive
and other equitable

- 7 -

 

relief, in addition to any other remedies available to the Corporation. All expenses, including,
without limitation, attorney’s fees and expenses incurred in connection with any legal proceeding
arising as a result of a breach or threatened breach of paragraph 7 of this Agreement shall be
borne by the losing party to the fullest extent permitted by law and the losing party hereby agrees
to indemnify and hold the other party harmless from and against all such expenses.

          g. Essential and Independent Agreements. It is understood by the parties hereto
that the Executive’s obligations and the restrictions and remedies set forth in this paragraph 7
are essential elements of this Agreement and that but for his agreement to comply with and/or agree
to such obligations, restrictions and remedies, the Corporation would not have entered into this
Agreement or employed (or continued to employ) him. The Executive’s obligations and the
restrictions and remedies set forth in this paragraph 7 are independent agreements and the
existence of any claim or claims by him against the Corporation under this Agreement or otherwise
will not excuse his breach of any of his obligations or affect the restrictions and remedies set
forth under this paragraph 7.

          h. Survival
of Terms; Representations. The Executive’s obligations under this
paragraph 7 hereof shall remain in full force and effect notwithstanding the termination of his
employment. He acknowledges that he is sophisticated in business, and that the restrictions and
remedies set forth in this paragraph 7 do not create an undue hardship on him and will not prevent
him from earning a livelihood. He further acknowledges that he has had a sufficient period of time
within which to review this Agreement, including, without limitation, this paragraph 7, with an
attorney of his choice and he has done so to the extent he desired. The Executive and the
Corporation agree that the restrictions and remedies contained in this paragraph 7 are reasonable
and necessary to protect the Corporation’s legitimate business interests regardless of the reason
for or circumstances giving rise to such termination and that he and the Corporation intend that
such restrictions and remedies shall be enforceable to the fullest extent permissible by law. The
Executive agrees that given the scope of the Corporation’s business and the sophistication of the
information highway, any further geographic limitation on such remedies and restrictions would deny
the Corporation the protection to which it is entitled hereunder. If it shall be found by a court
of competent jurisdiction that any such restriction or remedy is unenforceable but would be
enforceable if some part thereof were deleted or modified, then such restriction or remedy shall
apply with such modification as shall be necessary to make it enforceable to the fullest extent
permissible under law.

     8. Successors. This Agreement shall inure to the benefit of and be binding upon
the parties, their legal representatives and successors and assigns. However, the
Executive’s performance hereunder is personal to the Executive and shall not be assignable by
the Executive. The Corporation may assign this Agreement to any affiliate or to any successor
to all or substantially all of the business and/or assets of the Corporation, whether
directly or indirectly, by purchase, merger, consolidation, acquisition of stock, or
otherwise.

     9. Miscellaneous.

         a. Waiver; Amendment. The failure of a party to enforce any term,
provision, or condition of this Agreement at any time or times shall not be deemed a waiver of that
term, provision, or condition for the future, nor shall any specific waiver of a term,

- 8 -

 

provision, or condition at one time be deemed a waiver of such term, provision, or condition for
any future time or times. This Agreement may be amended or modified only by a writing signed by
both parties hereto.

          b. Governing Law. This Agreement shall be governed and construed in accordance
with the laws of the State of Delaware without giving effect to principles of conflicts of
law.

          c. Tax Withholding. The payments and benefits under this Agreement may be
compensation and as such may be included in either the Executive’s W-2 earnings statements or
1099 statements. The Corporation may withhold from any amounts payable under this Agreement
such federal, state or local taxes as shall be required to be withheld pursuant to
any applicable law or regulation.

          d. Paragraph Captions. Paragraph and other captions contained in this Agreement
are for reference purposes only and are in no way intended to describe, interpret, define or
limit the scope, extent or intent of this Agreement or any provision hereof.

          e. Severability. Each provision of this Agreement is intended to be severable.
If any term or provision hereof is illegal or invalid for any reason whatsoever,
such illegality or invalidity shall not affect the validity of the remainder of this
Agreement.

          f. Integrated Agreement. This Agreement constitutes the entire understanding
and agreement between the parties hereto with respect to the subject matter hereof,
and supersedes all prior and contemporaneous agreements, understandings, memoranda, term
sheets, conversations and negotiations. There are no agreements, understandings,
restrictions, representations or warranties between the parties other than those set forth
herein or herein provided for.

          g. Interpretation; Counterparts. No provision of this Agreement is to
be interpreted for or against any party because that party drafted such provision. For
purposes of this Agreement: “herein, “hereby,” “hereinafter,” “herewith,” “hereafter” and
“hereinafter” refer to this Agreement in its entirety, and not to any particular subsection
or paragraph. This Agreement may be executed in any number of counterparts, each of which
shall be deemed an original, and all of which shall constitute one and the same instrument.

          h. Notices. All notices and other communications hereunder shall be in
writing and shall be deemed to have been duly given if delivered by hand delivery, or by

issues or redeems Disqualified Stock or Preferred Stock subsequent to the
commencement of the period for which the Fixed Charge Coverage Ratio is being
calculated but prior to the event for which the calculation of the Fixed Charge
Coverage Ratio is made (the "CALCULATION DATE"), then the Fixed Charge Coverage
Ratio shall be calculated giving pro forma effect to such incurrence,
assumption, guarantee or repayment of Indebtedness, or such issuance or
redemption of Disqualified Stock or Preferred Stock, as if the same had occurred
at the beginning of the applicable four-quarter period. For purposes of making

four-quarter

                                      -13-
<PAGE>

reference period. If since the beginning of such period any Person (that
subsequently became a Restricted Subsidiary or was merged with or into the
Issuer or any Restricted Subsidiary since the beginning of such period) shall
have made any Investment, acquisition, disposition, merger or consolidation that
would have required adjustment pursuant to this definition, then the Fixed
Charge Coverage Ratio shall be calculated giving pro forma effect thereto for
such period as if such Investment, acquisition, disposition, merger or
consolidation had occurred at the beginning of the applicable four-quarter
period. For purposes of this definition, whenever pro forma effect is to be
given to an Investment, acquisition, disposition, merger or consolidation
(including the Transactions) and the amount of income or earnings relating
thereto, the pro forma calculations shall be determined in good faith by a
responsible financial or accounting Officer of the Issuer and shall comply with
the requirements of Rule 11-02 of Regulation S-X promulgated by the Commission,
except that such pro forma calculations may include operating expense reductions
for such period resulting from the transaction that is being given pro forma

have been taken or are reasonably expected to be taken within six months

termination of any contracts, reduction of costs related to administrative
functions, the termination of any personnel or the closing (or approval by the
Board of Directors of the Issuer of any closing) of any facility, as applicable,
provided that, in either case, such adjustments are set forth in an Officers'
Certificate signed by the Issuer's chief financial officer and another Officer
which states (i) the amount of such adjustment or adjustments, (ii) that such
adjustment or adjustments are based on the reasonable good faith beliefs of the
Officers executing such Officers' Certificate at the time of such execution and
(iii) that any related incurrence of Indebtedness is permitted pursuant to this
Indenture. If any Indebtedness bears a floating rate of interest and is being
given pro forma effect, the interest on such Indebtedness shall be calculated as
if the rate in effect on the Calculation Date had been the applicable rate for
the entire period (taking into account any Hedging Obligations applicable to
such Indebtedness if the related hedge has a remaining term in excess of twelve
months). Interest on a Capitalized Lease Obligation shall be deemed to accrue at
an interest rate reasonably determined by a responsible financial or accounting
officer of the Issuer to be the rate of interest implicit in such Capitalized
Lease Obligation in accordance with GAAP. For purposes of making the computation
referred to above, interest on any Indebtedness under a revolving credit
facility computed on a pro forma basis shall be computed based upon the average
daily balance of such Indebtedness during the applicable period. Interest on
Indebtedness that may optionally be determined at an interest rate based upon a
factor of a prime or similar rate, a eurocurrency interbank offered rate, or
other rate, shall be deemed to have been based upon the rate actually chosen,
or, if none, then based upon such optional rate chosen as the Issuer may
designate.

            "FIXED CHARGES" means, with respect to any Person for any period,
the sum of, without duplication, (a) Consolidated Interest Expense (excluding

or assumed, unless, in the case of any particular obligation, the instrument
creating or evidencing the same or pursuant to which the same is outstanding

acquisition, disposition, merger or consolidation, as if the same had occurred
at the beginning of the applicable period. In the event that the Issuer or any
Restricted Subsidiary incurs, assumes, guarantees or repays any Indebtedness or
issues or redeems Disqualified Stock or Preferred Stock subsequent to the
commencement of the Measurement Period for which the Leverage Ratio is being
calculated but prior to the event for which the calculation of the Leverage
Ratio is made, then the Leverage Ratio shall be calculated giving pro forma
effect to such incurrence, assumption, guarantee or repayment of Indebtedness,
or such issuance or redemption of Disqualified Stock or Preferred Stock, as if

                                 THE SECURITIES

SECTION 2.01. Form, Dating and Terms.

            (a) The aggregate principal amount of Securities that may be
authenticated and delivered under this Indenture is unlimited. The Initial
Securities issued on the date hereof will be in an aggregate principal amount of
$550,000,000. In addition, the Issuer may issue, from time to time in accordance
with the provisions of this Indenture, Additional Securities and Exchange
Securities. Furthermore, Securities may be authenticated and delivered upon
registration or transfer, or in lieu of, other Securities pursuant to Section
2.06, 2.07, 2.10 or 9.06 or in connection with a Change of Control Offer
pursuant to Section 4.09 or an Asset Sale Offer pursuant to Section 4.13.

            The Initial Securities shall be known and designated as "10% Senior
Subordinated Notes, Series A, due 2012" of the Issuer. Additional Securities
issued as securities bearing one of the restrictive legends described in Section
2.01(d) ("RESTRICTED SECURITIES") shall be known and designated as "10% Senior
Subordinated Notes, Series A, due 2012" of the Issuer. Additional Securities
issued other than as Restricted Securities shall be known and designated as "10%
Senior Subordinated Notes, Series B, due 2012" of the Issuer, and Exchange
Securities shall be known and designated as "10% Senior Subordinated Notes,
Series B, due 2012" of the Issuer.

            With respect to any Additional Securities, the Issuer shall set
forth in (a) a Board Resolution of the Issuer and (b) (i) an Officers'
Certificate or (ii) one or more indentures supplemental hereto, the following
information:

            (1) the aggregate principal amount of such Additional Securities to
      be authenticated and delivered pursuant to this Indenture;

                                      -38-
<PAGE>

            (2) the issue price and the issue date of such Additional
      Securities, including the date from which interest shall accrue; and

            (3) whether such Additional Securities shall be Restricted
      Securities issued in the form of 10% Senior Subordinated Notes, Series A,
      due 2012 or 10% Senior Subordinated Notes, Series B, due 2012.

            The Initial Securities, the Additional Securities and the Exchange
Securities shall be considered collectively as a single class for all purposes
of this Indenture. Holders of the Initial Securities, the Additional Securities
and the Exchange Securities will vote and consent together on all matters to
which such Holders are entitled to vote or consent as one class, and none of the
Holders of the Initial Securities, the Additional Securities or the Exchange
Securities shall have the right to vote or consent as a separate class on any
matter to which such Holders are entitled to vote or consent.

            If any of the terms of any Additional Securities are established by
action taken pursuant to Board Resolutions of the Issuer, a copy of an
appropriate record of such action shall be certified by the Secretary or any
Assistant Secretary of the Issuer and delivered to the Trustee at or prior to
the delivery of the Officers' Certificate or the indenture supplemental hereto
setting forth the terms of the Additional Securities.

            (b) The Initial Securities are being offered and sold by the Issuer
pursuant to the Securities Purchase Agreement. The Initial Securities and any
Additional Securities (if issued as Restricted Securities) (the "ADDITIONAL
RESTRICTED SECURITIES") will be resold initially only to (A) QIBs in reliance on
Rule 144A and (B) Non-U.S. Persons in reliance on Regulation S. Such Initial
Securities and Additional Restricted Securities may thereafter be transferred
to, among others, QIBs, purchasers in reliance on Regulation S and IAIs in
accordance with Rule 501 of the Securities Act, in each case, in accordance with
the procedure described herein. Additional Securities offered after the date
hereof may be offered and sold by the Issuer from time to time pursuant to one
or more purchase agreements in accordance with applicable law.

            Initial Securities and Additional Restricted Securities offered and
sold to QIBs in the United States of America in reliance on Rule 144A (the "RULE
144A NOTES") shall be issued in the form of a permanent global Security
substantially in the form of Exhibit A, which is hereby incorporated by
reference and made a part of this Indenture, including appropriate legends as
set forth in Section 2.01(d) (the "RULE 144A GLOBAL NOTE"), deposited with the
Trustee, as custodian for DTC, duly executed by the Issuer and authenticated by
the Trustee as hereinafter provided. The Rule 144A Global Note may be
represented by more than one certificate, if so required by DTC's rules
regarding the maximum principal amount to be represented by a single
certificate. The aggregate principal amount of the Rule 144A Global Note may
from time to time be increased or decreased by adjustments made on the records
of the Trustee, as custodian for DTC or its nominee, as hereinafter provided.

                                      -39-
<PAGE>

            Initial Securities and Additional Securities offered and sold
outside the United States of America (the "REGULATION S NOTES") in reliance on
Regulation S shall initially be issued in the form of a temporary global
Security (the "TEMPORARY REGULATION S GLOBAL NOTE"), without interest coupons.
Beneficial interests in the Temporary Regulation S Global Note will be exchanged
for beneficial interests in a corresponding permanent global Security, without
interest coupons, substantially in the form of Exhibit A including appropriate
legends as set forth in Section 2.01(d) (the "PERMANENT REGULATION S GLOBAL
NOTE" and, together with the Temporary Regulation S Global Note, each a
"REGULATION S GLOBAL NOTE") within a reasonable period after the expiration of
the Restricted Period (as defined below) upon delivery of the certification in
the form attached hereto as Exhibit F. Each Regulation S Global Note will be
deposited upon issuance with, or on behalf of, the Trustee as custodian for DTC
in the manner described in this Article Two for credit to the respective
accounts of the purchasers (or to such other accounts as they may direct) at
Euroclear or Clearstream. Prior to the 40th day after the later of the
commencement of the offering of the Initial Securities and the Issue Date (such
period through and including such 40th day, the "RESTRICTED PERIOD"), interests
in the Temporary Regulation S Global Note may only be held through Euroclear or
Clearstream (as indirect participants in DTC) unless exchanged for interests in
a Global Security in accordance with the transfer and certification requirements
described herein.

            Investors may hold their interests in the Regulation S Global Note
directly through Euroclear or Clearstream, if they are participants in such
systems, or indirectly through organizations which are participants in such
systems. After the expiration of the Restricted Period (but not earlier),
investors may also hold such interests through organizations other than
Euroclear or Clearstream that are participants in DTC's system. Euroclear and
Clearstream will hold such interests in the Regulation S Global Note on behalf
of their participants through customers' securities accounts in their respective
names on the books of their respective depositaries. Such depositaries, in turn,
will hold such interests in the applicable Regulation S Global Note in
customers' securities accounts in the depositaries' names on the books of DTC.

            The Regulation S Global Note may be represented by more than one
certificate, if so required by DTC's rules regarding the maximum principal
amount to be represented by a single certificate. The aggregate principal amount
of the Regulation S Global Note may from time to time be increased or decreased
by adjustments made on the records of the Trustee, as custodian for DTC or its
nominee, as hereinafter provided.

            Initial Securities and Additional Securities resold to IAIs (the
"INSTITUTIONAL ACCREDITED INVESTOR NOTES") in the United States of America shall
be issued in the form of a permanent global Security substantially in the form
of Exhibit A including appropriate legends as set forth in Section 2.01(d) (the
"INSTITUTIONAL ACCREDITED INVESTOR GLOBAL NOTE") deposited with the Trustee, as
custodian for DTC, duly executed by the Issuer and

                                      -40-
<PAGE>

authenticated by the Trustee as hereinafter provided. The Institutional
Accredited Investor Global Note may be represented by more than one certificate,
if so required by DTC's rules regarding the maximum principal amount to be
represented by a single certificate. The aggregate principal amount of the
Institutional Accredited Investor Global Note may from time to time be increased
or decreased by adjustments made on the records of the Trustee, as custodian for
DTC or its nominee, as hereinafter provided.

            Exchange Securities exchanged for interests in the Rule 144A Notes,
the Regulation S Notes and the Institutional Accredited Investor Notes will be
issued in the form of a permanent global Security, substantially in the form of
Exhibit A, which is hereby incorporated by reference and made a part of this
Indenture, deposited with the Trustee as hereinafter provided, including the
appropriate legend set forth in Section 2.01(d) (the "EXCHANGE GLOBAL NOTE").
The Exchange Global Note will be deposited upon issuance with, or on behalf of,
the Trustee as custodian for DTC, duly executed by the Issuer and authenticated
by the Trustee as hereinafter provided. The Exchange Global Note may be
represented by more than one certificate, if so required by DTC's rules
regarding the maximum principal amount to be represented by a single
certificate.

            The Rule 144A Global Note, the Regulation S Global Note, the
Institutional Accredited Investor Global Note and the Exchange Global Note are
sometimes collectively herein referred to as the "GLOBAL SECURITIES."

            The principal of (and premium, if any) and interest on the
Securities shall be payable at the office or agency of the Issuer maintained for
such purpose in the Borough of Manhattan, The City of New York, State of New
York, or at such other office or agency of the Issuer as may be maintained for
such purpose pursuant to Section 2.03; provided, however, that, at the option of
the Issuer, each installment of interest may be paid by (i) check mailed to
addresses of the Persons entitled thereto as such addresses shall appear on the
registry maintained by the Registrar or (ii) wire transfer to an account located
in the United States maintained by the payee. Payments in respect of Securities
represented by a Global Security (including principal, premium, if any, and
interest) will be made by wire transfer of immediately available funds to the
accounts specified by DTC. Payments in respect of Securities represented by
Definitive Securities (including principal, premium, if any, and interest) held
by a Holder will be made by wire transfer to a U.S. dollar account maintained by
the payee with a bank in the United States if such Holder elects payment by wire
transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than three Business Days immediately
preceding the relevant due date for payment (or such other date as the Trustee
may accept in its discretion).

            The Securities may have notations, legends or endorsements required
by law, stock exchange rule or usage, in addition to those set forth on Exhibit
A and in Section 2.01(d). The Issuer and the Trustee shall approve the forms of
the Securities and any

                                      -41-
<PAGE>

notation, endorsement or legend on them. Each Security shall be dated the date
of its authentication. The terms of the Securities set forth in Exhibit A are
part of the terms of this Indenture and, to the extent applicable, the Issuer,
the Guarantors and the Trustee, by their execution and delivery of this
Indenture, expressly agree to be bound by such terms.

            (c) Denominations. The Securities shall be issuable only in fully
registered form, without coupons, and only in denominations of $1,000 and an
integral multiple thereof.

            (d) Restrictive Legends. Unless and until (i) an Initial Security is
sold under an effective registration statement or (ii) an Initial Security is
exchanged for an Exchange Security in connection with an effective registration
statement, in each case pursuant to the Registration Rights Agreement or a
similar agreement,

            (1) the Rule 144A Global Note and the Institutional Accredited
Investor Global Note shall bear the legend set forth in Exhibit B hereto (the
"PRIVATE PLACEMENT LEGEND") on the face thereof.

            (2) the Regulation S Global Note shall bear the legend set forth in
Exhibit C hereto (the "REGULATION S LEGEND") on the face thereof.

            (3) Each Global Security, whether or not an Initial Security, shall
bear the legend set forth in Exhibit D hereto on the face thereof.

            (4) General. By its acceptance of any Security bearing the Private
Placement Legend, each Holder of such Security acknowledges the restrictions on
transfer of such Security set forth in this Indenture and in the Private
Placement Legend and agrees that it will transfer such Security only as provided
in this Indenture.

            The Registrar shall retain for a period of two years copies of all
letters, notices and other written communications received pursuant to this
Section 2.01. The Issuer shall have the right to inspect and make copies of all
such letters, notices or other written communications at any reasonable time
upon the giving of reasonable notice to the Registrar.

            (e) Book-Entry Provisions.

            (i) This Section 2.01(e) shall apply only to Global Securities
      deposited with the Trustee, as custodian for DTC.

            (ii) Each Global Security initially shall (x) be registered in the
      name of DTC for such Global Security or the nominee of DTC, (y) be
      delivered to the Trustee as custodian for DTC and (z) bear legends as set
      forth in Section 2.01(d).

                                      -42-
<PAGE>

            (iii) Members of, or participants in, DTC ("AGENT MEMBERS") shall
      have no rights under this Indenture with respect to any Global Security
      held on their behalf by DTC or by the Trustee as the custodian of DTC or
      under such Global Security, and DTC may be treated by the Issuer, the
      Trustee and any agent of the Issuer or the Trustee as the absolute owner
      of such Global Security for all purposes whatsoever. Notwithstanding the
      foregoing, nothing herein shall prevent the Issuer, the Trustee or any
      agent of the Issuer or the Trustee from giving effect to any written
      certification, proxy or other authorization furnished by DTC or impair, as
      between DTC and its Agent Members, the operation of customary practices of
      DTC governing the exercise of the rights of a Holder of a beneficial
      interest in any Global Security.

            (iv) In connection with any transfer of a portion of the beneficial
      interest in a Global Security pursuant to subsection (f) of this Section
      2.01 to beneficial owners who are required to hold Definitive Securities,
      the Securities Custodian shall reflect on its books and records the date
      and a decrease in the principal amount of such Global Security in an
      amount equal to the principal amount of the beneficial interest in the
      Global Security to be transferred, and the Issuer shall execute, and the
      Trustee shall authenticate and make available for delivery, one or more
      Definitive Securities of like tenor and amount.

            (v) In connection with the transfer of an entire Global Security to
      beneficial owners pursuant to subsection (f) of this Section 2.01, such
      Global Security shall be deemed to be surrendered to the Trustee for
      cancellation, and the Issuer shall execute, and the Trustee shall
      authenticate and make available for delivery, to each beneficial owner
      identified by DTC in exchange for its beneficial interest in such Global
      Security, an equal aggregate principal amount of Definitive Securities of
      authorized denominations.

            (vi) The registered Holder of a Global Security may grant proxies
      and otherwise authorize any person, including Agent Members and persons
      that may hold interests through Agent Members, to take any action which a
      Holder is entitled to take under this Indenture or the Securities.

            (vii) Any Holder of a Global Security shall, by acceptance of such
      Global Security, agree that transfers of beneficial interests in such
      Global Security may be effected only through a book-entry system
      maintained by (a) the Holder of such Global Security (or its agent) or (b)
      any Holder of a beneficial interest in such Global Security, and that
      ownership of a beneficial interest in such Global Security shall be
      required to be reflected in a book entry.

            (f) Definitive Securities. (i) Except as provided below, owners of
beneficial interests in Global Securities will not be entitled to receive
Definitive Securities. If required to do so pursuant to any applicable law or
regulation, beneficial owners may obtain

                                      -43-
<PAGE>

Definitive Securities in exchange for their beneficial interests in a Global
Security upon written request in accordance with DTC's and the Registrar's
procedures. In addition, Definitive Securities shall be transferred to all
beneficial owners in exchange for their beneficial interests in a Global
Security if (A) DTC notifies the Issuer that it is unwilling or unable to
continue as depositary for such Global Security or DTC ceases to be a clearing
agency registered under the Exchange Act, at a time when DTC is required to be
so registered in order to act as depositary, and in each case a successor
depositary is not appointed by the Issuer within 90 days of such notice or, (B)
the Issuer in its sole discretion executes and delivers to the Trustee and
Registrar an Officers' Certificate stating that such Global Security shall be so
exchangeable or (C) an Event of Default has occurred and is continuing and the
Registrar has received a request from DTC. In the event of the occurrence of any
of the events specified in clause (A), (B) or (C) of the preceding sentence, the
Issuer shall promptly make available to the Trustee a reasonable supply of
Definitive Securities in fully registered form without interest coupons.

            (ii) Any Definitive Security delivered in exchange for an interest
      in a Global Security pursuant to Section 2.01(e)(iv) or (v) shall, except
      as otherwise provided by Section 2.06(c), bear the applicable legend
      regarding transfer restrictions applicable to the Definitive Security set
      forth in Section 2.01(d).

            (iii) In connection with the exchange of a portion of a Definitive
      Security for a beneficial interest in a Global Security, the Trustee shall
      cancel such Definitive Security, and the Issuer shall execute, and the
      Trustee shall authenticate and make available for delivery, to the
      transferring Holder a new Definitive Security representing the principal
      amount not so transferred.

SECTION 2.02. Execution and Authentication.

            One Officer shall sign the Securities for the Issuer by manual or
facsimile signature. If an Officer whose signature is on a Security no longer
holds that office at the time the Trustee authenticates the Security, the
Security shall be valid nevertheless.

            A Security shall not be valid and shall not be entitled to any
benefit under this Indenture until an authorized signatory of the Trustee
manually authenticates the Security. The signature of the Trustee on a Security
shall be conclusive evidence that such Security has been duly and validly
authenticated, issued and delivered under this Indenture. A Security shall be
dated the date of its authentication.

            At any time and from time to time after the execution and delivery
of this Indenture, the Trustee shall authenticate and make available for
delivery: (1) Initial Securities for original issue on the Issue Date in an
aggregate principal amount of $550,000,000, (2) subject to the terms of this
Indenture, Additional Securities for original issue in an unlimited principal
amount and (3) Exchange Securities for issue only in a Registered

                                      -44-
<PAGE>

Exchange Offer or upon resale under an effective Shelf Registration Statement,
and only in exchange for Initial Securities or Additional Securities of an equal
principal amount, in each case upon a written order of the Issuer signed by an
Officer of the Issuer (the "ISSUER ORDER"). Such Issuer Order shall specify
whether the Securities will be in the form of Definitive Securities or Global
Securities, the amount of the Securities to be authenticated and the date on
which the original issue of Securities is to be authenticated and whether the
Securities are to be Initial Securities, Additional Securities or Exchange
Securities.

            The Trustee may appoint an agent (the "AUTHENTICATING AGENT")
reasonably acceptable to the Issuer to authenticate the Securities. Any such
appointment shall be evidenced by an instrument signed by a Responsible Officer,
a copy of which shall be furnished to the Issuer. Unless limited by the terms of
such appointment, any such Authenticating Agent may authenticate Securities
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by the Authenticating
Agent. An Authenticating Agent has the same rights as any Registrar, Paying
Agent or agent for service of notices and demands.

            In case the Issuer, pursuant to Article Five, shall be consolidated
or merged with or into any other Person or shall convey, transfer, lease or
otherwise dispose of its properties and assets substantially as an entirety to
any Person, and the successor Person resulting from such consolidation, or
surviving such merger, or into which the Issuer shall have been merged, or the
Person which shall have received a conveyance, transfer, lease or other
disposition as aforesaid, shall have executed an indenture supplemental hereto
with the Trustee pursuant to Article Five, any of the Securities authenticated
or delivered prior to such consolidation, merger, conveyance, transfer, lease or
other disposition may, from time to time, at the request of the successor
Person, be exchanged for other Securities executed in the name of the successor
Person with such changes in phraseology and form as may be appropriate, but
otherwise in substance of like tenor as the Securities surrendered for such
exchange and of like principal amount; and the Trustee, upon Issuer Order of the
successor Person, shall authenticate and make available for delivery Securities
as specified in such order for the purpose of such exchange. If Securities shall
at any time be authenticated and delivered in any new name of a successor Person
pursuant to this Section 2.02 in exchange or substitution for or upon
registration of transfer of any Securities, such successor Person, at the option
of the Holders but without expense to them, shall provide for the exchange of
all Securities at the time outstanding for Securities authenticated and
delivered in such new name.

SECTION 2.03. Registrar and Paying Agent.

            The Issuer shall maintain (a) an office or agency where Securities
may be presented for registration of transfer or for exchange (the "REGISTRAR"),
(b) an office or agency in the Borough of Manhattan, The City of New York, the
State of New York, where the Securities may be presented for payment (the
"PAYING AGENT") and (c) an office or agency

                                      -45-
<PAGE>

where notices and demands to or upon the Issuer, if any, in respect of the
Securities and this Indenture may be served. The Registrar shall keep a register
of the Securities and of their transfer and exchange. The Issuer may have one or
more co-registrars and one or more additional Paying Agents. The term
"REGISTRAR" includes any co-registrars. The Issuer or any Affiliate thereof may
act as Registrar or Paying Agent. The term "Paying Agent" includes any
additional paying agent.

            The Issuer shall enter into an appropriate agency agreement, which
shall incorporate the provisions of the TIA, with any Agent that is not a party
to this Indenture. The agreement shall implement the provisions of this
Indenture that relate to such Agent. The Issuer shall notify the Trustee of the
name and address of any such Agent. If the Issuer fails to maintain a Registrar
or any required co-registrar or Paying Agent, or fails to give the foregoing
notice, the Trustee shall act as such and shall be entitled to appropriate
compensation in accordance with Section 7.07.

            The Issuer initially appoints the Trustee as Registrar, Paying Agent
and Agent for service of notices and demands in connection with the Securities
and this Indenture.

            The Issuer may change the paying agents, the registrars or the
transfer agents without prior notice to the Holders. Any of the Issuer's
Wholly-Owned Subsidiaries organized in the United States may act as Paying
Agent, Registrar or transfer agent.

            The Issuer may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Issuer of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York for such purposes.

SECTION 2.04. Paying Agent To Hold Assets in Trust.

            Each Paying Agent shall hold in trust for the benefit of the Holders
or the Trustee all money held by the Paying Agent for the payment of principal
of or premium or interest on the Securities (whether such money has been paid to
it by the Issuer, one or more of the Guarantors or any other obligor on the
Securities), and the Issuer and each Paying Agent shall notify the Trustee of
any Default by the Issuer (or any other obligor on the Securities) in making any
such payment. Money held in trust by a Paying Agent need not be segregated
except as required by law and in no event shall a Paying Agent be liable for any
interest on any money received by it hereunder. The Issuer at any time may
require a Paying Agent to pay all money held by it to the Trustee and account
for any funds disbursed and the Trustee may at any time during the continuance
of any Event of Default specified in Section 6.01(1) or (2), upon written
request to a Paying Agent, require such Paying Agent to pay forthwith all money
so held by it to the Trustee and to account for any funds disbursed. Upon making
such payment, such Paying Agent shall have no further liability for the money

                                      -46-
<PAGE>

delivered to the Trustee. The provisions of Article Ten applicable to the
Trustee shall apply to the Paying Agents, mutatis mutandis.

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
Holders. If the Trustee is not the Registrar, the Issuer shall furnish to the
Trustee at least two (2) Business Days prior to 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 Holders, which list may be conclusively relied upon by the Trustee.

SECTION 2.06. Transfer and Exchange.

            (a) The following provisions shall apply with respect to any
proposed transfer of a Rule 144A Note or an Institutional Accredited Investor
Note prior to the date which is two years after the later of the date of its
original issue and the last date on which the Issuer or any Affiliate of the
Issuer was the owner of such Securities (or any predecessor thereto) (the
"RESALE RESTRICTION TERMINATION DATE"):

         (i) a transfer of a Rule 144A Note or an Institutional Accredited
      Investor Note or a beneficial interest therein to a QIB shall be made upon
      the representation of the transferee in the form as set forth on the
      reverse of the Security that it is purchasing for its own account or an
      account with respect to which it exercises sole investment discretion and
      that it and any such account is a "qualified institutional buyer" within
      the meaning of Rule 144A, and is aware that the sale to it is being made
      in reliance on Rule 144A and acknowledges that it has received such
      information regarding the Issuer as it has requested pursuant to Rule 144A
      or has determined not to request such information and that it is aware
      that the transferor is relying upon its foregoing representations in order
      to claim the exemption from registration provided by Rule 144A;

         (ii) a transfer of a Rule 144A Note or an Institutional Accredited
      Investor Note or a beneficial interest therein to an IAI shall be made
      upon receipt by the Trustee or its agent of a certificate substantially in
      the form set forth in Exhibit E from the proposed transferee and, if
      requested by the Issuer or the Trustee, the delivery of an opinion of
      counsel, certification and/or other information satisfactory to each of
      them; and

         (iii) a transfer of a Rule 144A Note or an Institutional Accredited
      Investor Note or a beneficial interest therein to a Non-U.S. Person shall
      be made upon receipt by the Trustee or its agent of a certificate
      substantially in the form set forth in Exhibit F from the proposed
      transferee and, if requested by the Issuer or the Trustee,

                                      -47-
<PAGE>

      the delivery of an opinion of counsel, certification and/or other
      information satisfactory to each of them.

            (b) The following provisions shall apply with respect to any
proposed transfer of a Regulation S Note prior to the expiration of the
Restricted Period:

         (i) a transfer of a Regulation S Note or a beneficial interest therein
      to a QIB shall be made upon the representation of the transferee, in the
      form of assignment on the reverse of the certificate, that it is
      purchasing the Security for its own account or an account with respect to
      which it exercises sole investment discretion and that it and any such
      account is a "qualified institutional buyer" within the meaning of Rule
      144A, and is aware that the sale to it is being made in reliance on Rule
      144A and acknowledges that it has received such information regarding the
      Issuer as it has requested pursuant to Rule 144A or has determined not to
      request such information and that it is aware that the transferor is
      relying upon its foregoing representations in order to claim the exemption
      from registration provided by Rule 144A;

         (ii) a transfer of a Regulation S Note or a beneficial interest therein
      to an IAI shall be made upon receipt by the Trustee or its agent of a
      certificate substantially in the form set forth in Exhibit E from the
      proposed transferee and, if requested by the Issuer or the Trustee, the
      delivery of an opinion of counsel, certification and/or other information
      satisfactory to each of them; and

         (iii) a transfer of a Regulation S Note or a beneficial interest
      therein to a Non-U.S. Person shall be made upon receipt by the Trustee or
      its agent of a certificate substantially in the form set forth in Exhibit
      F hereof from the proposed transferee and, if requested by the Issuer or
      the Trustee, receipt by the Trustee or its agent of an opinion of counsel,
      certification and/or other information satisfactory to each of them.

            After the expiration of the Restricted Period, interests in the
Regulation S Note may be transferred in accordance with applicable law without
requiring the certification set forth in Exhibit F or any additional
certification.

            (c) Restricted Securities Legend. Upon the transfer, exchange or
replacement of Securities not bearing a Restricted Securities Legend, the
Registrar shall deliver Securities that do not bear a Restricted Securities
Legend. Upon the transfer, exchange or replacement of Securities bearing a
Restricted Securities Legend, the Registrar shall deliver only Securities that
bear a Restricted Securities Legend unless (i) Initial Securities are being
exchanged for Exchange Securities in a Registered Exchange Offer in which case
the Exchange Securities shall not bear a Restricted Securities Legend, (ii) an
Initial Security is being transferred pursuant to the Shelf Registration
Statement or other effective registration statement or (iii) there is delivered
to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer and
the Trustee to the effect that neither such

                                      -48-
<PAGE>

legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act. Any Additional
Securities sold in a registered offering shall not be required to bear the
Restricted Securities Legend. Any Additional Restricted Securities sold in a
private offering shall bear the legends set forth in Exhibits B and C, as
applicable.

            (d) The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 2.01 or this Section
2.06. The Issuer shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time upon the
giving of reasonable prior written notice to the Registrar.

            (e) Obligations with Respect to Transfers and Exchanges of
Securities.

         (i) To permit registrations of transfers and exchanges, the Issuer
      shall, subject to the other terms and conditions of this Article Two,
      execute and the Trustee shall authenticate Definitive Securities and
      Global Securities at the Registrar's request.

         (ii) No service charge shall be made to a Holder for any registration
      of transfer or exchange, but the Issuer may require the Holder to pay a
      sum sufficient to cover any transfer tax, assessments, or similar
      governmental charge payable in connection therewith (other than any such
      transfer taxes, assessments or similar governmental charges payable upon
      exchange or transfer pursuant to Section 9.06).

         (iii) The Issuer (and the Registrar) shall not be required to register
      the transfer of or exchange of any Security for a period beginning (1) 15
      days before the mailing of a notice of an offer to repurchase or redeem
      Securities and ending at the close of business on the day of such mailing,
      (2) selected for redemption in whole or in part pursuant to Article Three,
      except the unredeemed portion of any Security being redeemed in part, and
      (3) during a Change of Control Offer, an Alternate Offer or an Asset Sale
      Offer if such Security is tendered pursuant to such Change of Control
      Offer, Alternate Offer or Asset Sale Offer and not withdrawn.

         (iv) Prior to the due presentation for registration of transfer of any
      Security, the Issuer, the Trustee, the Paying Agent or the Registrar may
      deem and treat the person in whose name a Security is registered as the
      absolute owner of such Security for the purpose of receiving payment of
      principal of, premium, if any, and interest on such Security and for all
      other purposes whatsoever, including without limitation the transfer or
      exchange of such Security, whether or not such Security is overdue, and
      none of the Issuer, the Trustee, the Paying Agent or the Registrar shall
      be affected by notice to the contrary.

                                      -49-
<PAGE>

         (v) Any Definitive Security delivered in exchange for an interest in a
      Global Security pursuant to Section 2.01(e) shall, except as otherwise
      provided by Section 2.06(c), bear the applicable legend regarding transfer
      restrictions applicable to the Global Security set forth in Section
      2.01(d).

         (vi) All Securities issued upon any transfer or exchange pursuant to
      the terms of this Indenture shall evidence the same debt and shall be
      entitled to the same benefits under this Indenture as the Securities
      surrendered upon such transfer or exchange.

            (f) No Obligation of the Trustee.

            (i) The Trustee shall have no responsibility or obligation to any
      beneficial owner of a Global Security, a member of, or a participant in,
      DTC or other Person with respect to the accuracy of the records of DTC or
      its nominee or of any participant or member thereof, with respect to any
      ownership interest in the Securities or with respect to the delivery to
      any participant, member, beneficial owner or other Person (other than DTC)
      of any notice (including any notice of redemption) or the payment of any
      amount or delivery of any Securities (or other security or property) under
      or with respect to such Securities. All notices and communications to be
      given to the Holders and all payments to be made to Holders in respect of
      the Securities shall be given or made only to or upon the order of the
      registered Holders (which shall be DTC or its nominee in the case of a
      Global Security). The rights of beneficial owners in any Global Security
      shall be exercised only through DTC subject to the applicable rules and
      procedures of DTC. The Trustee may rely and shall be fully protected in
      relying upon information furnished by DTC with respect to its members,
      participants and any beneficial owners.

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

SECTION 2.07. Replacement Securities.

            If a mutilated Security is surrendered to the Registrar or the
Trustee, or if the Holder of a Security claims that the Security has been lost,
destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall
authenticate a replacement Security if the Holder of such Security furnishes to
the Issuer and the Trustee evidence reasonably acceptable to them

                                      -50-
<PAGE>

of the ownership and the destruction, loss or theft of such Security and if the
requirements of Section 8-405 of the New York Uniform Commercial Code as in
effect on the date of this Indenture are met. If required by the Trustee or the
Issuer, an indemnity bond shall be posted, sufficient in the judgment of all to
protect the Issuer, the Guarantors, if any, the Trustee or any Paying Agent from
any loss that any of them may suffer if such Security is replaced. The Issuer
may charge such Holder for the Issuer's reasonable out-of-pocket expenses in
replacing such Security and the Trustee may charge the Issuer for the Trustee's
expenses (including, without limitation, attorneys' fees and disbursements) in
replacing such Security. Every replacement Security shall constitute a
contractual obligation of the Issuer.

SECTION 2.08. Outstanding Securities.

            The Securities outstanding at any time are all the Securities that
have been authenticated by the Trustee except (a) those canceled by it, (b)
those delivered to it for cancellation, (c) to the extent set forth in Sections
8.01 and 8.02, on or after the date the conditions set forth in Section 8.01 or
8.02 have been satisfied and (d) those Securities described in this Section as
not outstanding. A Security does not cease to be outstanding because the Issuer
or any of its Affiliates holds the Security (subject to the provisions of
Section 2.09).

            If a Security is replaced pursuant to Section 2.07 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide purchaser in whose hands such Security is a legal, valid
and binding obligation of the Issuer. A mutilated Security ceases to be
outstanding upon surrender of such Security and replacement thereof pursuant to
Section 2.07.

            If the principal amount of any Security is considered paid under
Section 4.01, it ceases to be outstanding and interest ceases to accrue. If on a
Redemption Date or the Maturity Date the Trustee or Paying Agent (other than the
Issuer or an Affiliate thereof) holds U.S. Legal Tender or U.S. Government
Securities sufficient to pay all of the principal and interest due on the
Securities payable on that date, then on and after that date such Securities
cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09. Treasury Securities.

            In determining whether the Holders of the required principal amount
of Securities have concurred in any direction, waiver or consent, Securities
owned by the Issuer or any of its Affiliates shall be disregarded, except that,
for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Securities that a
Responsible Officer of the Trustee actually knows are so owned shall be
disregarded.

                                      -51-
<PAGE>

SECTION 2.10. Temporary Securities.

            Until definitive Securities are ready for delivery, the Issuer may
prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may
have variations that the Issuer considers appropriate for temporary Securities.
Without unreasonable delay, the Issuer shall prepare and the Trustee shall
authenticate definitive Securities in exchange for temporary Securities. Until
such exchange, temporary Securities shall be entitled to the same rights,
benefits and privileges as definitive Securities. Notwithstanding the foregoing,
so long as the Securities are represented by a Global Security, such Global
Security may be in typewritten form.

SECTION 2.11. Cancellation.

            The Issuer at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for transfer, exchange or payment. The
Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent
(other than the Issuer or a Subsidiary), and no one else, shall cancel and, at
the written direction of the Issuer, shall dispose of all Securities surrendered
for transfer, exchange, payment or cancellation in accordance with its customary
procedures. Subject to Section 2.07, the Issuer may not issue new Securities to
replace Securities that it has paid or delivered to the Trustee for
cancellation. If the Issuer or any Guarantor shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction
of the Indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation pursuant to this Section 2.11.

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

SECTION 2.12. Defaulted Interest.

            If the Issuer defaults in a payment of interest on the Securities,
it shall, unless the Trustee fixes another Record Date pursuant to Section 6.10,
pay the defaulted interest then borne by the Securities, plus (to the extent
lawful) any interest payable on the defaulted interest, in accordance with the
terms hereof. The Issuer may pay the defaulted interest to the

                                      -52-
<PAGE>

persons who are Holders on a subsequent special Record Date, which special
Record Date shall be the fifteenth day next preceding the date fixed by the
Issuer for the payment of defaulted interest or the next succeeding Business Day
if such date is not a Business Day. At least 15 days before any such subsequent
special Record Date, the Issuer shall mail to each Holder, with a copy to the
Trustee, a notice that states the subsequent special Record Date, the payment
date and the amount of defaulted interest, and interest payable on such
defaulted interest, if any, to be paid. The Issuer may make payment of any
defaulted interest in any other lawful manner not inconsistent with the
requirements (if applicable) of any securities exchange on which the Securities
may be listed and, upon such notice as may be required by such exchange, if,
after written notice given by the Issuer to the Trustee of the proposed payment
pursuant to this sentence, such manner of payment shall be deemed practicable by
the Trustee.

SECTION 2.13. CUSIP, ISIN and "Common Code" Numbers.

            The Issuer in issuing the Securities may use CUSIP numbers, ISINs
and "Common Code" numbers (if then generally in use) and, if so, the Trustee
shall use, as applicable, CUSIP numbers, ISINs and "Common Code" 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 or
accuracy of such numbers, either as printed on the Securities or as contained in
any notice of a redemption, that reliance may be placed only on the other
identification number(s) printed on the Securities. The Issuer shall advise the
Trustee of any change in the CUSIP numbers, ISINs and "Common Code" numbers.

SECTION 2.14. Deposit of Moneys.

            Prior to 10:00 a.m. New York City time, on each Interest Payment
Date, Maturity Date, Redemption Date, Change of Control Payment Date and Asset
Sale Payment Date, the Issuer shall have deposited with the Paying Agent in
immediately available funds U.S. Legal Tender sufficient to make cash payments,
if any, due on such Interest Payment Date, Maturity Date, Redemption Date,
Change of Control Payment Date and Asset Sale Payment Date, as the case may be,
in a timely manner which permits the Paying Agent to remit payment to the
Holders on such Interest Payment Date, Maturity Date, Redemption Date, Change of
Control Payment Date and Asset Sale Payment Date, as the case may be. The
principal and interest on Global Securities shall be payable to the Depository
or its nominee, as the sole registered owner and the sole Holder of the Global
Securities represented thereby. The principal and interest on Definitive
Securities shall be payable, either in person or by mail, at the office of the
applicable Paying Agent.

SECTION 2.15. Computation of Interest.

            Interest on the Securities shall be computed on the basis of a
360-day year of twelve 30-day months and actual days elapsed.

                                      -53-
<PAGE>

SECTION 2.16. Calculation of Principal Amount of Securities.

            The aggregate principal amount of the Securities, at any date of
determination, shall be principal amount of the Securities at such date of
determination. With respect to any matter requiring consent, waiver, approval or
other action of the Holders of a specified percentage of the principal amount of
all the Securities, such percentage shall be calculated, on the relevant date of
determination, by dividing (a) the principal amount, as of such date of
determination, of Securities, the Holders of which have so consented, by (b) the
aggregate principal amount, as of such date of determination, of the Securities
then outstanding, in each case, as determined in accordance with the preceding
sentence, and Section 2.08 of this Indenture. Any such calculation made pursuant
to this Section 2.16 shall be made by the Issuer and delivered to the Trustee
pursuant to an Officers' Certificate.

                                 ARTICLE THREE

                                   REDEMPTION

SECTION 3.01. Notices to Trustee.

            If the Issuer elects to redeem Securities pursuant to Section 5 or
Section 6 of the Securities, it shall notify the Trustee in writing of the
Redemption Date, the Redemption Price and the principal amount of Securities to
be redeemed. The Issuer shall give notice of redemption to the Paying Agent and
Trustee at least 30 days but not more than 60 days before the Redemption Date
(unless a shorter notice shall be agreed to by the Trustee in writing), together
with an Officers' Certificate stating that such redemption will comply with the
conditions contained herein.

SECTION 3.02. Selection of Securities To Be Redeemed.

            If less than all of the Securities are to be redeemed at any time,
the Trustee will select Securities for redemption as follows:

            (1) if the Securities are listed on any national securities
      exchange, in compliance with the requirements of the principal national
      securities exchange on which the Securities are listed; or

            (2) if the Securities are not listed on any securities exchange, on
      a pro rata basis, by lot or by such method as the Trustee deems fair and
      appropriate.

            No Securities of $1,000 or less shall be redeemed in part.

SECTION 3.03. Notice of Redemption.

            At least 30 days but not more than 60 days before a Redemption Date,
the Issuer shall mail a notice of redemption by first class mail, postage
prepaid, to each Holder whose Securities are to be redeemed at its registered
address, except that redemption notices may be mailed more than 60 days prior to
a Redemption Date if the notice is issued in connection with a defeasance of the
Securities or a satisfaction and discharge of this Indenture. At the Issuer's
request, the Trustee shall forward the notice of redemption in the Issuer's name
and at the Issuer's expense; provided that in such case, the Trustee has
received notice from the Issuer at least 31 days, but not more than 60 days,
before a Redemption Date (unless a shorter notice shall be agreed to in writing
by the Trustee). Securities called for redemption become due on the date fixed
for redemption. On and after the Redemption Date, interest ceases to accrue on
Securities or portions of them called for redemption. Each notice of redemption
shall identify the Securities (including the CUSIP number) to be redeemed and
shall state:

            (1) the Redemption Date;

            (2) the Redemption Price and the amount of accrued interest, if any,
      to be paid;

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

            (4) that Securities called for redemption must be surrendered to the
      Paying Agent to collect the Redemption Price, plus accrued interest, if
      any;

            (5) that, unless the Issuer defaults in making the redemption
      payment, interest on Securities called for redemption ceases to accrue on
      and after the Redemption Date, and the only remaining right of the Holders
      of such Securities is to receive payment of the Redemption Price upon
      surrender to the Paying Agent of the Securities redeemed;

            (6) if any Security is being redeemed in part, the portion of the
      principal amount of such Security to be redeemed and that, after the
      Redemption Date, and upon surrender of such Security, a new Security or
      Securities in aggregate principal amount equal to the unredeemed portion
      thereof will be issued;

            (7) if fewer than all the Securities are to be redeemed, the
      identification of the particular Securities (or portion thereof) to be
      redeemed, as well as the aggregate principal amount of Securities to be
      redeemed and the aggregate principal amount of Securities to be
      outstanding after such partial redemption;

                                      -55-
<PAGE>

            (8) the CUSIP Number, ISIN and/or "Common Code" number, if any,
      printed on the Securities being redeemed;

            (9) that no representation is made as to the correctness or accuracy
      of the CUSIP number or ISIN and/or "Common Code" number, if any, listed in
      such notice or printed on the Securities; and

            (10) the Section of the Securities pursuant to which the Securities
      are to be redeemed.

            The notice, if mailed in a manner herein provided, shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security designated for redemption in whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security. Notices of redemption may not be conditional.

SECTION 3.04. Effect of Notice of Redemption.

            Once notice of redemption is mailed in accordance with Section 3.03,
Securities called for redemption become due and payable on the Redemption Date
and at the Redemption Price plus accrued interest, if any. Upon surrender to the
Trustee or Paying Agent, such Securities called for redemption shall be paid at
the Redemption Price (which shall include accrued interest thereon to the
Redemption Date), but installments of interest, the maturity of which is on or
prior to the Redemption Date, shall be payable to Holders of record at the close
of business on the relevant Record Dates. On and after the Redemption Date
interest shall cease to accrue on Securities or portions thereof called for
redemption.

SECTION 3.05. Deposit of Redemption Price.

            With respect to the Securities, prior to 10:00 a.m., New York time,
on the Redemption Date, the Issuer shall deposit with the Paying Agent (or, if
the Issuer or a Wholly Owned Subsidiary is a Paying Agent, shall segregate and
hold in trust) U.S. Legal Tender and/or U.S. Government Securities sufficient to
pay the redemption price of and accrued interest on all Securities or portions
thereof to be redeemed on that date other than Securities or portions of
Securities called for redemption that have been delivered by the Issuer to the
Trustee for cancellation. On and after the Redemption Date, interest shall cease
to accrue on the Securities or portions thereof called for redemption so long as
the Issuer has deposited with the Paying Agent funds sufficient to pay the
principal of, plus accrued and unpaid interest on, the Securities.

                                      -56-
<PAGE>

SECTION 3.06. Securities Redeemed in Part.

            If any Security is to be redeemed in part only, the notice of
redemption that relates to such Security shall state the portion of the
principal amount thereof to be redeemed. A new Security in principal amount
equal to the unredeemed portion of the original Security shall be issued in the
name of the Holder thereof upon cancellation of the original Security.

                                  ARTICLE FOUR

            (a) The Issuer shall pay the principal of (and premium, if any) and
interest on the Securities on the dates and in the manner provided in the
Securities and this Indenture. An installment of principal of or interest on the
Securities shall be considered paid on the date it is due if the Trustee or
Paying Agent (other than the Issuer or an Affiliate thereof) holds on that date
U.S. Legal Tender and/or U.S. Government Securities designated for and
sufficient to pay the installment. Interest on the Securities will be computed
on the basis of a 360-day year comprised of twelve 30-day months.

            (b) The Issuer shall pay interest on overdue principal (including,
without limitation, post petition interest in a proceeding under any Bankruptcy
Law), and overdue interest, to the extent lawful, at the same rate per annum
borne by the Securities.

SECTION 4.02. Maintenance of Office or Agency.

            (a) The Issuer shall maintain the offices or agencies required under
Section 2.03. The Issuer shall give prompt written notice to the Trustee of the
location, and any change in the location, of such offices or agencies. If at any
time the Issuer shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the address of the
Trustee set forth in Section 12.02.

            (b) The Issuer may also from time to time designate one or more
other offices or agencies where the Securities may be presented or surrendered
for any or all such purposes and may from time to time rescind such
designations. The Issuer will give prompt written notice to the Trustee of any
such designation or rescission and of any change in the location of any such
other office or agency.

                                      -57-

            (c) The Issuer hereby initially designates the Corporate Trust
Office of the Trustee as one such office or agency of the Issuer in accordance
with Section 2.03.

SECTION 4.03. Corporate Existence.

            Except as otherwise permitted by Article Five, the Issuer shall do

effect its corporate existence in accordance with its organizational documents.

SECTION 4.04. Payment of Taxes and Other Claims.

            The Issuer shall, and shall cause each of its Subsidiaries to, pay
or discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all material taxes, assessments and governmental charges levied
or imposed upon it or any of its respective Subsidiaries or upon the income,
profits or property of it or any of its respective Subsidiaries and (b) all
lawful claims for labor, materials and supplies except, in each case, any such
tax, assessment, charge or claim as is being contested in good faith by
appropriate actions or where the failure to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim is not materially
adverse to the Holders.

SECTION 4.05. Maintenance of Properties and Insurance.

            (a) The Issuer shall cause all material properties owned by or
leased by it or any of its Restricted Subsidiaries used or useful to the conduct
of its business or the business of any of its Restricted Subsidiaries to be
maintained and kept in normal condition, repair and working order and supplied
with all necessary equipment and shall cause to be made all repairs, renewals,
replacements, and betterments thereof, all as in its judgment may be necessary,
so that the business carried on in connection therewith may be properly and
advantageously conducted at all times; provided, however, that nothing in this
Section 4.05 shall prevent the Issuer or any of its Restricted Subsidiaries from
discontinuing the use, operation or maintenance of any of such properties, or
disposing of any of them, if such discontinuance or disposal is, in the judgment
of the Board of Directors of the Issuer or any such Restricted Subsidiary
desirable in the conduct of the business of the Issuer or any such Restricted
Subsidiary; provided, further, that nothing in this Section 4.05 shall prevent
the Issuer or any of its Restricted Subsidiaries from discontinuing or disposing
of any properties to the extent otherwise permitted by this Indenture.

            (b) The Issuer shall maintain, and shall cause its Restricted
Subsidiaries to maintain, insurance with responsible carriers against such risks
and in such amounts, and with such deductibles, retentions, self insured amounts
and co-insurance provisions, as are appropriate for a business of this type and
size as determined in good faith by the Issuer, including property and casualty
loss, workers' compensation and interruption of business insurance.

            (a) The Issuer shall deliver to the Trustee, within 90 days after
the close of each fiscal year commencing with the fiscal year ending December
31, 2004, an Officers' Certificate stating that a review of the activities of
the Issuer and its Restricted Subsidiaries has been made under the supervision
of the signing Officers with a view to determining whether the Issuer has kept,
observed, performed and fulfilled its obligations under this Indenture and
further stating, as to each such Officer signing such certificate, that to the
best of such Officer's knowledge, the Issuer during such preceding fiscal year
has kept, observed, performed and fulfilled each and every such covenant and no
Default occurred during such year and at the date of such certificate there is
no Default that has occurred and is continuing or, if such signers do know of
such Default, the certificate shall describe its status with particularity. The
Officers' Certificate shall also notify the Trustee should the Issuer elect to
change the manner in which it fixes its fiscal year end.

            (b) The Issuer shall deliver to the Trustee as soon as possible, and
in any event within five days after the Issuer becomes aware of the occurrence
of any Default, an Officers' Certificate specifying the Default and describing
its status with particularity and the action proposed to be taken thereto.

Issuer will provide written notice to the Trustee of any change in its fiscal
year.

SECTION 4.07. Compliance with Laws.

            The Issuer shall comply, and shall cause each of its Restricted
Subsidiaries to comply, with all applicable statutes, rules, regulations, orders
and restrictions of the United States, all states and municipalities thereof,
and of any governmental department, commission, board, regulatory authority,
bureau, agency and instrumentality of the foregoing, in respect of the conduct
of their respective businesses and the ownership of their respective properties,
except, in any such case, to the extent the failure to so comply would not,
individually or in the aggregate, reasonably be expected to have a material
adverse effect on the business, financial condition or results of operations of
the Issuer and its Restricted Subsidiaries taken as a whole.

SECTION 4.08. Waiver of Stay, Extension or Usury Laws.

            The Issuer covenants (to the extent permitted by applicable law)
that it will not at any time insist upon, plead, or in any manner whatsoever
claim or take the benefit or advantage of, any stay or extension law or any
usury law or other law that would prohibit or forgive the Issuer from paying all
or any portion of the principal of and/or interest on the Securities as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture, and (to the
extent

                                      -59-

<PAGE>

permitted by applicable law) the Issuer hereby expressly waives all benefit or
advantage of any such law, and covenants (to the extent permitted by applicable
law) that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

SECTION 4.09. Change of Control.

            (a) If a Change of Control occurs, unless the Issuer at such time
has the right and gives notice of redemption under Section 5 or Section 6 of the
Securities, each Holder will have the right to require the Issuer to repurchase
all or any part (equal to $1,000 or an integral multiple of $1,000) of that
Holder's Securities pursuant to a Change of Control Offer (the "CHANGE OF
CONTROL OFFER") on the terms set forth in this Indenture. In the Change of
Control Offer, the Issuer will offer to pay an amount in cash (the "CHANGE OF
CONTROL PAYMENT") equal to 101% of the aggregate principal amount of Securities
repurchased, plus accrued and unpaid interest and Additional Interest, if any,
on the Securities repurchased, to the date of purchase.

            (b) Within 30 days following any Change of Control, unless the
Issuer at such time has the right and gives notice of redemption under Section 5
or Section 6 of the Securities, the Issuer will mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and offering to repurchase Securities on the date (the "CHANGE OF CONTROL
PAYMENT DATE") specified in the notice, which date will be no earlier than 30
days and no later than 60 days from the date such notice is mailed, pursuant to
the procedures required by this Indenture and described in such notice. Such
notice shall state:

            (1) that the Change of Control Offer is being made pursuant to this
      Section 4.09 and that all Securities tendered and not withdrawn will be
      accepted for payment;

            (2) the purchase price (including the amount of accrued interest and
      any Additional Interest) and the Change of Control Payment Date;

            (3) that any Security not tendered will continue to accrue interest;

            (4) that, unless the Issuer defaults in making payment therefor, any
      Security accepted for payment pursuant to the Change of Control Offer
      shall cease to accrue interest after the Change of Control Payment Date;

            (5) that Holders electing to have a Security purchased pursuant to a
      Change of Control Offer will be required to surrender the Security, with
      the form entitled "Option of Holder to Elect Purchase" on the reverse of
      the Security completed, to the Paying Agent at the address specified in
      the notice prior to the close of business on the third Business Day prior
      to the Change of Control Payment Date;

                                      -60-

<PAGE>

            (6) that Holders will be entitled to withdraw their election if the
      Paying Agent receives, not later than the second Business Day prior to the
      Change of Control Payment Date, a telegram, facsimile transmission or
      letter setting forth the name of the Holder, the principal amount of the
      Securities the Holder delivered for purchase and a statement that such
      Holder is withdrawing such Holder's election to have such Security
      purchased;

            (7) that Holders whose Securities are purchased only in part will be
      issued new Securities in a principal amount equal to the unpurchased
      portion of the Securities surrendered; and

            (8) the circumstances and relevant facts regarding such Change of
      Control.

            (c) On the Change of Control Payment Date, the Issuer will, to the
extent lawful:

            (1) accept for payment all Securities or portions of Securities
      properly tendered pursuant to the Change of Control Offer;

            (2) deposit with the Paying Agent an amount equal to the Change of
      Control Payment in respect of all Securities or portions of Securities
      properly tendered; and

            (3) deliver or cause to be delivered to the Trustee the Securities
      properly accepted together with an Officers' Certificate stating the
      aggregate principal amount of Securities or portions of Securities being
      purchased by the Issuer.

            (d) The Paying Agent will promptly mail to each Holder of Securities
properly tendered the Change of Control Payment for such Securities, and the
Trustee will promptly authenticate and mail (or cause to be transferred by book
entry) to each Holder a new Security equal in principal amount to any
unpurchased portion of the Securities surrendered, if any; provided that each
such new Security will be in a principal amount of $1,000 or an integral
multiple of $1,000.

            Prior to complying with any of the provisions of this Section 4.09,
but in any event within 90 days following a Change of Control, to the extent
required to permit the Issuer to comply with this Section 4.09, the Issuer will
either repay all outstanding Senior Debt or obtain the requisite consents, if
any, under all agreements governing outstanding Senior Debt. The Issuer will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date. However, if the Change of
Control Payment Date is on or after an interest Record Date and on or before the
related Interest Payment Date, any accrued and unpaid interest shall be paid to
the Person in whose name a Security is registered at the close of business on
such Record Date, and no additional

                                      -61-

<PAGE>

interest shall be payable to Holders who tender Securities pursuant to the
Change of Control Offer.

            (e) Notwithstanding the foregoing, the Issuer shall not be required
to make a Change of Control Offer, as provided above, if, in connection with or
in contemplation of any Change of Control, it or a third party has made an offer
to purchase (an "ALTERNATE OFFER") any and all Securities validly tendered at a
cash price equal to or higher than the Change of Control Payment and has
purchased all Securities properly tendered in accordance with the terms of such
Alternate Offer. The Alternate Offer must comply with all the other provisions
applicable to the Change of Control Offer, shall remain, if commenced prior to
the Change of Control, open for acceptance until the consummation of the Change
of Control and must permit Holders to withdraw any tenders of Securities made
into the Alternate Offer until the final expiration or consummation thereof,
subject to Sections 4.09(b)(5) and (6).

            (f) The Issuer will comply, and will cause any third party making a
Change of Control Offer or an Alternate Offer to comply, with the requirements
of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent such laws and regulations are applicable in
connection with a Change of Control Offer or an Alternate Offer. To the extent
the provisions of any applicable securities laws or regulations conflict with
the provisions of this Indenture relating to a Change of Control Offer, the
Issuer will not be deemed to have breached its obligations under this Indenture
by virtue of complying with such laws or regulations.

SECTION 4.10. Incurrence of Indebtedness and Issuance of Preferred Stock.

            (a) The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly or directly liable, contingently or
otherwise, with respect to (collectively "INCUR") any Indebtedness (including
Acquired Debt), and will not permit any of its Restricted Subsidiaries to issue
any shares of Preferred Stock; provided, however, that the Issuer and any
Restricted Subsidiary that is a Guarantor may incur Indebtedness (including
Acquired Debt) and any Restricted Subsidiary that is a Guarantor may issue
Preferred Stock if the Fixed Charge Coverage Ratio for the Issuer's most
recently ended four full fiscal quarters for which internal financial statements
are available immediately preceding the date on which such additional
Indebtedness is incurred or such Preferred Stock is issued would have been (x)
prior to January 1, 2006, at least 2.0 to 1.0 and (y) on and after January 1,
2006, at least 2.375 to 1.0, in each case determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom) (the "COVERAGE
RATIO EXCEPTION"), as if the additional Indebtedness had been incurred or the
Preferred Stock had been issued, as the case may be, and the application of
proceeds therefrom had occurred at the beginning of such four-quarter period.

                                      -62-

      together with the incurrence of the guarantees thereunder and the issuance
      and creation of letters of credit and bankers' acceptances thereunder

      principal amount equal to the face amount thereof), up to an aggregate
      principal amount, of $725.0 million outstanding at any one time, less the
      amount of all mandatory principal payments (with respect to revolving
      borrowings and letters of credit, only to the extent revolving commitments
      are correspondingly reduced) actually made by the borrower thereunder in
      respect of Indebtedness thereunder with Net Proceeds from Asset Sales;

            (2) the incurrence by the Issuer and the Guarantors of Indebtedness
      represented by the Securities (including any Guarantee thereof) issued on

      assets or the Capital Stock of any Person owning such assets) within 270
      days before or after such purchase, lease or improvement in an aggregate
      principal amount that, when aggregated with the principal amount of all
      other Indebtedness then outstanding and incurred pursuant to this clause
      (4) and any Indebtedness that refunds or refinances such Indebtedness,
      does not exceed the greater of (x) $25.0 million and (y) 1.0% of Total
      Assets;

            (5) Indebtedness incurred by the Issuer or any Restricted Subsidiary
      constituting reimbursement obligations with respect to letters of credit
      issued in the ordinary course of business, including without limitation

      disability or other employee benefits or property, casualty or liability
      insurance or self-insurance or other Indebtedness with respect to
      reimbursement-type obligations regarding workers' compensation claims;
      provided, however, that upon the drawing of such letters of credit or the
      incurrence of such Indebtedness, such obligations are reimbursed within 30
      days following such drawing or incurrence;

      Subsidiary, other than guarantees of Indebtedness incurred by any Person
      acquiring all or any portion of such business, assets or a Subsidiary for
      the purpose of financing such acquisition; provided, however, that (A)
      such Indebtedness is not reflected on the balance sheet of the Issuer or
      any Restricted Subsidiary (contingent obligations referred to in a
      footnote to financial statements and not otherwise reflected on the
      balance sheet will not be deemed to be reflected on such balance sheet for
      purposes of this clause (A)) and (B) the maximum assumable liability in
      respect of all such Indebtedness shall at no time exceed the gross
      proceeds including noncash proceeds (the fair market value of such noncash
      proceeds being measured at the time received and without giving effect to
      any subsequent changes in value) actually received by the Issuer and any
      Restricted Subsidiaries in connection with such disposition;

      Subsidiary or any subsequent transfer of any such Indebtedness (except to
      the Issuer or a Restricted Subsidiary) shall be deemed, in each case, to
      constitute the incurrence of such Indebtedness by the issuer thereof and
      (B) if the Issuer is the obligor on such Indebtedness, such Indebtedness
      is expressly subordinated in right of payment to all obligations of the
      Issuer with respect to the Securities;

      in any such Restricted Subsidiary ceasing to be a Restricted Subsidiary or
      any other subsequent transfer of any such shares of Preferred Stock
      (except to the Issuer or a Restricted Subsidiary) shall be deemed in each
      case to be an issuance of such shares of Preferred Stock;

            (9) Hedging Obligations of the Issuer or any Restricted Subsidiary
      (excluding Hedging Obligations entered into for speculative purposes) for
      the purpose of limiting (A) interest rate risk with respect to any

      preference of all other Indebtedness and Preferred Stock then outstanding
      and incurred pursuant to this clause (11), does not at any one time

      Indebtedness or Preferred Stock incurred pursuant to this clause (11)
      shall cease to be deemed incurred or outstanding for purposes of this
      clause (11) but shall be deemed incurred for the purposes of Section
      4.10(a) from and after the first date on which the Issuer or such
      Restricted Subsidiary could have incurred such Indebtedness or Preferred
      Stock under Section 4.10(a) without reliance on this clause (11));

            (12) (x) any guarantee by the Issuer or a Guarantor of Indebtedness
      of any Restricted Subsidiary so long as the incurrence of such
      Indebtedness incurred by such Restricted Subsidiary is permitted under the
      terms of this Indenture; provided that if such Indebtedness is by its
      express terms subordinated in right of payment to the Securities or the
      Guarantee of such Restricted Subsidiary, as applicable, any such guarantee
      of such Guarantor with respect to such Indebtedness shall be subordinated
      in right of payment to such Guarantor's Guarantee with respect to the
      Securities substantially to the same extent as such Indebtedness is
      subordinated to the Securities or the Guarantee of such Restricted
      Subsidiary, as applicable, (y) any guarantee by a Non-Guarantor Restricted

      (3) above, this clause (13) and clauses (14) and (17) below or any
      Indebtedness issued to so refund or refinance such Indebtedness including
      additional Indebtedness incurred to pay premiums and fees in connection
      therewith (the "REFINANCING INDEBTEDNESS") prior to its respective
      maturity; provided, however, that such Refinancing Indebtedness (A) has a
      Weighted Average Life to Maturity at the time such Refinancing
      Indebtedness is incurred which is not less than the remaining Weighted
      Average Life to Maturity of the Indebtedness being refunded or refinanced,
      (B) to the extent such Refinancing Indebtedness refinances Indebtedness
      subordinated or pari passu to the Securities or the Guarantees, such
      Refinancing Indebtedness is subordinated or pari passu to the Securities
      or the Guarantees at least to the same extent as the Indebtedness being
      refinanced or

      connection with or in contemplation of such acquisition or merger; and
      provided, further, that after giving effect to such incurrence of
      Indebtedness either (A) the Issuer would be permitted to incur at least
      $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception
      or (B) the Fixed Charge Coverage Ratio would be greater than immediately

      otherwise permitted hereunder or (b) if the Issuer could not incur $1.00
      of additional Indebtedness pursuant to the Coverage Ratio Exception hereof
      after giving effect to such borrowing, Indebtedness of Foreign
      Subsidiaries of the Issuer incurred for working capital purposes,
      provided, however, that the aggregate principal amount of Indebtedness
      incurred under this clause (18) which, when aggregated with the principal
      amount of all other Indebtedness then outstanding and incurred pursuant to
      this clause (18), does not exceed the greater of (x) $65.0 million and (y)
      2.50% of Total Assets; and

      Issuer or any Guarantor to current or former officers, directors and
      employees, their respective estates, spouses or former spouses to finance
      the purchase or redemption of Equity Interests of Holdco permitted by
      Section 4.11.

            (c) For purposes of determining compliance with this Section 4.10,
in the event that an item of proposed Indebtedness meets the criteria of more
than one of the categories of Permitted Debt described in clauses (1) through
(19) above, or is entitled to be incurred pursuant to Section 4.10(a), the
Issuer will be permitted to classify and later reclassify such item of
Indebtedness in any manner that complies with this covenant, and such item of
Indebtedness will be treated as having been incurred pursuant to only one of
such categories. Accrual of interest, the accretion of accreted value and the
payment of interest in the form of additional Indebtedness will not be deemed to
be an incurrence of Indebtedness for purposes of this covenant. Notwithstanding
the foregoing, Indebtedness under the Credit Agreement outstanding on the date
on which Securities are first issued and authenticated under this Indenture will
be deemed to have been incurred on such date in reliance on the exception
provided by clause (1) of the definition of "Permitted Debt" in Section 4.10(b)
and the Issuer shall not be permitted to reclassify all or any portion of such
Indebtedness. The maximum amount of Indebtedness that the Issuer and its
Restricted Subsidiaries may incur pursuant to this covenant shall not be deemed
to be exceeded, with respect to any outstanding Indebtedness, solely as a result
of fluctuations in the exchange rate of currencies.

SECTION 4.11. Restricted Payments.

      to purchase such Equity Interests (other than Disqualified Stock) or (y)
      dividends or distributions by a Restricted Subsidiary to the Issuer or any
      other Restricted Subsidiary (and if such Restricted Subsidiary is not a
      Wholly Owned Subsidiary, to its other holders of common stock on a pro
      rata basis) so long as, in the case of any dividend or distribution
      payable on or in respect of any class or series of securities issued by a
      Restricted Subsidiary other than a Wholly Owned Subsidiary, the Issuer or
      a Restricted Subsidiary receives at least its pro rata share of such
      dividend or distribution in accordance with its Equity Interests in such
      class or series of securities);

      Guarantees) (other than (x) Indebtedness permitted under clauses (7) and
      (8) of the definition of "Permitted Debt" in Section 4.10(b) or (y) the
      purchase, repurchase or other acquisition of Indebtedness subordinated or
      junior in right of payment to the Securities, purchased in anticipation of
      satisfying a sinking fund obligation, principal installment or final
      maturity, in each case due within one year of the date of purchase,
      repurchase or acquisition); or

            (D) make any Restricted Investment (all such payments and other
      actions set forth in these clauses (A) through (D) being collectively
      referred to as "RESTRICTED PAYMENTS"),

      to the Coverage Ratio Exception; and

            (3) such Restricted Payment, together with the aggregate amount of
      all other Restricted Payments made by the Issuer and the Restricted

            period (taken as one accounting period) from the Issue Date to the
            end of the Issuer's most recently ended fiscal quarter for which
            internal financial statements are available at the time of such
            Restricted Payment (or, in the case such Consolidated Net Income for
            such period is a deficit, minus 100% of such deficit), plus

      after the Issue Date;

            (7) Investments in Unrestricted Subsidiaries having an aggregate
      fair market value, taken together with all other Investments made pursuant
      to this clause (7) that are at the time outstanding, after giving effect
      to the sale of an Unrestricted Subsidiary to the extent the proceeds of
      such sale received by the Issuer and/or its Restricted Subsidiaries
      consist of cash and/or marketable securities, not to exceed the greater of
      $15.0 million and 1.0% of Total Assets at the time of such Investment

            Restricted Subsidiaries; and

                  (E) fees and expenses other than to Affiliates related to an

<PAGE>

            (15) the declaration and payment of dividends to Holdco of the net

      be used as described in the Offering Memorandum; or

            (16) cash dividends or distributions of the Solid Edge Excess
      Proceeds; provided that immediately after giving effect to such Restricted
      Payment, the Leverage Ratio would not exceed 3.75 to 1.00;

provided, however, that at the time of, and after giving effect to, any
Restricted Payment permitted under clauses (5), (6), (7), (9), (11), (14) and
(16) above, no Default or Event of Default shall have occurred and be continuing
or would occur as a consequence thereof.

            (c) The amount of all Restricted Payments (other than cash) will be
the fair market value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by the Issuer or such
Subsidiary, as the case may be, pursuant to the Restricted Payment. The fair
market value of any assets or securities that are required to be valued by this
Section 4.11 will be determined in good faith by the Board of Directors of the
Issuer. The Issuer's determination must be based upon an opinion or appraisal
issued by an Independent Financial Advisor if the fair market value exceeds
$25.0 million.

            (d) The Issuer will not permit any Unrestricted Subsidiary to become
a Restricted Subsidiary except pursuant to the second to last sentence of the
definition of "Unrestricted Subsidiary." For purposes of designating any
Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding investments
by the Issuer and the Restricted Subsidiaries (except to the extent repaid) in
the Subsidiary so designated will be deemed to be Restricted Payments in an
amount determined as set forth in the second paragraph of the definition of
"Investments." Such designation will be permitted only if a Restricted Payment
in such amount would be permitted at such time under this Section 4.11 or the
definition of "Permitted Investments" and if such Subsidiary otherwise meets the
definition of an "Unrestricted Subsidiary."

SECTION 4.12. Liens.

            (a) The Issuer will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, create, incur, assume or suffer to exist
any Lien (other than Permitted Liens) that secures obligations under any
Indebtedness ranking pari passu with or subordinated to the Securities or a
related Guarantee on any asset or property of the Issuer or any such Restricted
Subsidiary, or any income or profits therefrom, or assign or convey any right to
receive income therefrom, unless:

                                      -74-

<PAGE>

            (1) in the case of Liens securing Indebtedness subordinated to the
      Securities or the Guarantees, the Securities and any related Guarantees
      are secured by a Lien on such property, assets or proceeds that is senior
      in priority to such Liens; or

            (2) in all other cases, the Securities and any related Guarantees
      are equally and ratably secured.

            (b) Notwithstanding the foregoing, Section 4.12(a) shall not apply
to:

            (i) Liens existing on the Issue Date to the extent and in the manner
      such Liens are in effect on the Issue Date;

            (ii) Liens securing the Securities and the related Guarantees and
      the Exchange Securities (including Exchange Securities issued in exchange
      for Additional Securities issued in accordance with the terms of this
      Indenture) and the related Guarantees;

            (iii) Liens securing Senior Debt or Guarantor Senior Debt and the
      related guarantees of such Senior Debt or Guarantor Senior Debt; and

            (iv) Permitted Liens.

SECTION 4.13. Asset Sales.

            (a) The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless:

            (1) the Issuer (or such Restricted Subsidiary, as the case may be)
      receives consideration at the time of the Asset Sale at least equal to the
      fair market value of the assets or Equity Interests issued or sold or
      otherwise disposed of;

            (2) in the case of Asset Sales involving consideration in excess of
      $10.0 million, the fair market value is determined by the Issuer's Board
      of Directors and evidenced by a Board Resolution set forth in an Officers'
      Certificate delivered to the Trustee; and

            (3) except for any Permitted Asset Swap, at least 75% of the
      consideration received in the Asset Sale by the Issuer or such Restricted
      Subsidiary is in the form of cash or Cash Equivalents.

For purposes of clause (3) above, the amount of (i) any liabilities (as shown on
the Issuer's or such Restricted Subsidiary's most recent balance sheet or in the
notes thereto) of the Issuer or any Restricted Subsidiary (other than
liabilities that are by their terms subordinated to the Securities or the
Guarantees) that are assumed by the transferee of any such assets and from

                                      -75-

<PAGE>

which the Issuer and all Restricted Subsidiaries have been validly released by
all creditors in writing, (ii) any securities received by the Issuer or such
Restricted Subsidiary from such transferee that are converted by the Issuer or
such Restricted Subsidiary into cash (to the extent of the cash received) within
180 days following the closing of such Asset Sale and (iii) any Designated
Noncash Consideration received by the Issuer or any of its Restricted
Subsidiaries in such Asset Sale having an aggregate fair market value (as
determined in good faith by the Board of Directors of the Issuer), taken
together with all other Designated Noncash Consideration received pursuant to
this clause (iii) that is at that time outstanding, not to exceed the greater of
(x) $50.0 million and (y) 2.0% of Total Assets at the time of the receipt of
such Designated Noncash Consideration (with the fair market value of each item
of Designated Noncash Consideration being measured at the time received without
giving effect to subsequent changes in value), shall be deemed to be cash for
purposes of this Section 4.13(a) and for no other purpose.

            (b) Within 365 days after the receipt of any Net Proceeds from an
Asset Sale, the Issuer may apply those Net Proceeds at its option:

            (1) to permanently reduce Obligations under Senior Debt of the
      Issuer (and to correspondingly reduce commitments with respect thereto) or
      Indebtedness that ranks pari passu with the Securities (provided that if
      the Issuer shall so reduce Obligations under such Indebtedness of the
      Issuer that ranks pari passu with the Securities, it will equally and
      ratably reduce Obligations under the Securities by making an offer (in
      accordance with the procedures set forth below for an Asset Sale Offer) to
      all Holders to purchase at a purchase price equal to 100% of the principal
      amount thereof, plus accrued and unpaid interest and Additional Interest,
      if any, on the pro rata principal amount of Securities) or Indebtedness of
      a Restricted Subsidiary, in each case, other than Indebtedness owed to the
      Issuer or an Affiliate of the Issuer;

            (2) to an investment in (A) any one or more businesses; provided
      that such investment in any business is in the form of the acquisition of
      Capital Stock and results in the Issuer or a Restricted Subsidiary owning
      an amount of the Capital Stock of such business such that it constitutes a
      Restricted Subsidiary, (B) capital expenditures or (C) other assets, in
      each of (A), (B) and (C), used or useful in a Permitted Business; and/or

            (3) to an investment in (A) any one or more businesses; provided
      that such investment in any business is in the form of the acquisition of
      Capital Stock and it results in the Issuer or a Restricted Subsidiary
      owning an amount of the Capital Stock of such business such that it
      constitutes a Restricted Subsidiary, (B) properties or (C) assets that, in
      each of (A), (B) and (C), replace the businesses, properties and assets
      that are the subject of such Asset Sale.

                                      -76-

<PAGE>

            (c) When the aggregate amount of Net Proceeds not applied or
invested in accordance with the preceding paragraph ("EXCESS PROCEEDS") exceeds
$20.0 million, the Issuer will make an offer (an "ASSET SALE OFFER") to all
Holders and holders of Indebtedness that ranks pari passu with the Securities
and contains provisions similar to those set forth in this Indenture with
respect to offers to purchase with the proceeds of sales of assets to purchase,
on a pro rata basis, the maximum principal amount of Securities and such other
pari passu Indebtedness that may be purchased out of the Excess Proceeds (the
"ASSET SALE OFFER AMOUNT"). The offer price in any Asset Sale Offer will be
equal to 100% of principal amount thereof, plus accrued and unpaid interest and
Additional Interest, if any, to the date of purchase (the "ASSET SALE PAYMENT"),
and will be payable in cash.

            (d) Pending the final application of any Net Proceeds, the Issuer
may temporarily reduce revolving credit borrowings or otherwise invest the Net
Proceeds in any manner that is not prohibited by this Indenture.

            (e) If any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Issuer may use those Excess Proceeds for any purpose not
otherwise prohibited by this Indenture. If the aggregate principal amount of
Securities tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Trustee will select the Securities to be purchased on a pro rata
basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds
will be reset at zero.

            (f) Upon the commencement of an Asset Sale Offer, the Issuer shall
send, by first class mail, a notice to the Trustee and to each Holder at its
registered address. The notice shall contain all instructions and materials
necessary to enable such Holder to tender Securities pursuant to the Asset Sale
Offer. Any Asset Sale Offer shall be made to all Holders. The notice, which
shall govern the terms of the Asset Sale Offer, shall state:

            (1) that the Asset Sale Offer is being made pursuant to this Section
      4.13;

            (2) the Asset Sale Offer Amount, the Asset Sale Payment and the date
      on which Securities tendered and accepted for payment shall be purchased,
      which date shall be at least 30 days and no later than 60 days from the
      date such notice is mailed (the "ASSET SALE PAYMENT DATE");

            (3) that any Securities not tendered or accepted for payment shall
      continue to accrue interest;

            (4) that, unless the Issuer defaults in making such payment, any
      Securities accepted for payment pursuant to the Asset Sale Offer shall
      cease to accrue interest after the Asset Sale Payment Date;

                                      -77-

<PAGE>

            (5) that Holders electing to have a Security purchased pursuant to
      any Asset Sale Offer shall be required to surrender the Security, with the
      form entitled "Option of Holder To Elect Purchase" on the reverse of the
      Securities completed, or transfer such Security by book-entry transfer, to
      the Paying Agent at the address specified in the notice at least three
      days before the Asset Sale Payment Date;

            (6) that Holders shall be entitled to withdraw their election if the
      Paying Agent receives, not later than the second Business Day prior to the
      Asset Sale Payment Date, a notice setting forth the name of the Holder,
      the principal amount of the Security the Holder delivered for purchase and
      a statement that such Holder is withdrawing such Holder's election to have
      such Security purchased;

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

            (8) that Holders whose Securities were purchased only in part shall
      be issued new Securities equal in principal amount to the unpurchased
      portion of the Securities surrendered (or transferred by book-entry
      transfer); provided that such Securities shall be in denominations of
      $1,000 or integral multiples $1,000.

            (g) On the Asset Sale Payment Date, the Issuer shall, to the extent
lawful: (1) accept for payment all Securities or portions thereof properly
tendered pursuant to the Asset Sale Offer; (2) deposit with the Paying Agent
U.S. Legal Tender and/or U.S. Government Securities sufficient to pay the Asset
Sale Payment in respect of all Securities or portions thereof so tendered; and
(3) deliver or cause to be delivered to the Trustee the Securities so accepted
together with an Officers' Certificate stating the aggregate principal amount of
Securities or portions thereof being repurchased by the Issuer. The Issuer shall
publicly announce the results of the Asset Sale Offer on the Asset Sale Payment
Date.

            (h) The Paying Agent shall promptly mail to each Holder so tendered
the Asset Sale Payment for such Securities, and the Trustee shall promptly
authenticate pursuant to an Issuer Order and mail (or cause to be transferred by
book entry) to each Holder a new Security equal in principal amount to any
unrepurchased portion of the Securities surrendered, if any; provided that each
such new Security shall be in a principal amount of $1,000 or an integral
multiple of $1,000. However, if the Asset Sale Payment Date is on or after an
interest Record Date and on or before the related Interest Payment Date, any
accrued and unpaid interest shall be paid to the Person in whose name a Security
is registered at the close of business on such Record Date, and no additional
interest shall be payable to Holders who tender Securities pursuant to the Asset
Sale Offer.

                                      -78-

<PAGE>

            (i) The Issuer will comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent those laws and regulations are applicable in connection with each
repurchase of Securities pursuant to an Asset Sale Offer. To the extent that the
provisions of any securities laws or regulations conflict with this Section
4.13, the Issuer will comply with the applicable securities laws and regulations
and will not be deemed to have breached its obligations under this Section 4.13
by virtue of such conflict.

SECTION 4.14. Transactions with Affiliates.

            (a) The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each, an "AFFILIATE TRANSACTION") involving aggregate
consideration in excess of $3.5 million, unless:

            (1) the Affiliate Transaction is on terms that are no less favorable
      to the Issuer or the relevant Restricted Subsidiary than those that would
      have been obtained in a comparable transaction by the Issuer or such
      Restricted Subsidiary with an unrelated Person; and

            (2) the Issuer delivers to the Trustee:

                  (a) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $10.0 million, a Board Resolution approving such Affiliate
            Transaction set forth in an Officers' Certificate certifying that
            such Affiliate Transaction complies with this Section 4.14 and that
            such Affiliate Transaction has been approved by a majority of the
            disinterested members of the Board of Directors; and

                  (b) with respect to any Affiliate Transaction or series of
            related Affiliate Transactions involving aggregate consideration in
            excess of $50.0 million, an opinion as to the fairness to the
            Holders of such Affiliate Transaction from a financial point of view
            issued by an Independent Financial Advisor.

            (b) The restrictions set forth in Section 4.14(a) do not apply to:

            (1) transactions between or among the Issuer and/or any Restricted
      Subsidiary or any entity that becomes a Restricted Subsidiary as a result

      the Issuer or Holdco or their Subsidiaries.

SECTION 4.15. Dividend and Other Payment Restrictions Affecting Subsidiaries.

            (a) The Issuer will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or permit to exist or become
effective any consensual encumbrance or restriction on the ability of any such
Restricted Subsidiary to:

            (1) pay dividends or make any other distributions on its Capital
      Stock to the Issuer or any of its Restricted Subsidiaries, or with respect
      to any other interest or participation in, or measured by, its profits, or

      to the Credit Agreement or related documents or (y) on the Issue Date,
      including, without limitation, pursuant to Existing Indebtedness and
      related documentation;

            (2) this Indenture, the Securities and the Guarantees (including any
      Exchange Securities and related Guarantees);

            (3) purchase money obligations or other obligations described in
      Section 4.10(b)(4) for property acquired in the ordinary course of
      business that in each case impose restrictions of the nature discussed in

            (4) applicable law or any applicable rule, regulation or order;

            (5) any agreement or other instrument of a Person acquired by the
      Issuer or any Restricted Subsidiary in existence at the time of such
      acquisition (but not created in contemplation thereof), which encumbrance
      or restriction is not applicable to any Person, or the properties or
      assets of any Person, other than the Person, or the property or assets of
      the Person, so acquired;

            (6) contracts for the sale of assets, including, without limitation,
      customary restrictions with respect to a Subsidiary pursuant to an
      agreement that has been entered into for the sale or disposition of all or
      substantially all of the Capital Stock or assets of such Subsidiary;

            (7) secured Indebtedness otherwise permitted to be incurred pursuant

            (8) restrictions on cash or other deposits or net worth imposed by
      customers under contracts entered into in the ordinary course of business;

      Restricted Subsidiary that is a Guarantor that is incurred subsequent to
      the Issue Date pursuant to Section 4.10 or (ii) that is incurred by a
      Foreign Subsidiary of the Issuer subsequent to the Issue Date pursuant to
      clauses (1), (11) or (18) of Section 4.10(b);

            (10) customary provisions in joint venture agreements and other

<PAGE>

            (11) customary provisions contained in leases, subleases, licenses
      or asset sale agreements and other agreements; and

            (12) any encumbrances or restrictions of the type referred to in

      replacements or refinancings of the contracts, instruments or obligations
      referred to in clauses (1) through (11) of this Section 4.15(b), provided
      that such amendments, modifications, restatements, renewals, increases,
      supplements, refundings, replacements or refinancings are, in the good
      faith judgment of the Issuer's Board of Directors, no more restrictive,
      taken as a whole, with respect to such dividend and other payment
      restrictions than those contained in the dividend or other payment
      restrictions prior to such amendment, modification, restatement, renewal,
      increase, supplement, refunding, replacement or refinancing.

SECTION 4.16. Additional Subsidiary Guarantees.

            The Issuer will cause each Restricted Subsidiary that Guarantees any
Indebtedness of the Issuer or any of its Guarantors to execute and deliver to
the Trustee a Guarantee pursuant to which such Restricted Subsidiary will
unconditionally Guarantee, on a joint and several basis, the full and prompt
payment of the principal of, premium, if any and interest on the Securities on a
senior subordinated basis and all other obligations under this Indenture.
Notwithstanding the foregoing, in the event any Guarantor is released and
discharged in full from all of its obligations under Guarantees of (1) each
Credit Agreement and (2) all other Indebtedness of the Issuer and its Restricted
Subsidiaries, then the Guarantee of such Guarantor shall be automatically and
unconditionally released or discharged; provided, that such Restricted
Subsidiary has not incurred any Indebtedness or issued any Preferred Stock in
reliance on its status as a Guarantor under Section 4.10 unless such Guarantor's
obligations under such Indebtedness or Preferred Stock, as the case may be, so
incurred are satisfied in full and discharged or are otherwise permitted under
one of the exceptions available at the time of such release to Restricted
Subsidiaries under Section 4.10(b).

            Each Guarantee will be limited to an amount not to exceed the
maximum amount that can be guaranteed by that Restricted Subsidiary without
rendering the Guarantee, as it relates to such Restricted Subsidiary, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer or
similar laws affecting the rights of creditors generally.

            Each Guarantee shall be released in accordance with Article Eleven.

                                      -83-

SECTION 4.17. Reports to Holders.

            (a) Whether or not required by the Commission, so long as any
Securities are outstanding, if not filed electronically with the Commission
through the Commission's Electronic Data Gathering, Analysis, and Retrieval
System (or any successor system), the Issuer will furnish to the Holders, within
the time periods specified in the Commission's rules and regulations:

            (1) all quarterly and annual financial information that would be
      required to be contained in a filing with the Commission on Forms 10-Q and
      10-K if the Issuer were required to file such Forms, including a
      "Management's Discussion and Analysis of Financial Condition and Results
      of Operations" and, with respect to the annual information only, a report
      on the annual financial statements by the Issuer's certified independent
      accountants; and

            (2) all current reports that would be required to be filed with the
      Commission on Form 8-K if the Issuer were required to file such reports.

            (b) In addition, whether or not required by the Commission, after
the consummation of the Exchange Offer or the effectiveness of the Shelf
Registration Statement, the Issuer will file a copy of all of the information
and reports referred to in clauses (1) and (2) above with the Commission for
public availability within the time periods specified in the Commission's rules
and regulations (unless the Commission will not accept such a filing) and make
such information available to securities analysts and prospective investors upon
request. In addition, the Issuer has agreed that, for so long as any Securities
remain outstanding, it will furnish to the Holders and to securities analysts
and prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act.

            (c) In addition, if at any time Holdco becomes a Guarantor (there
being no obligation of Holdco to do so), holds no material assets other than
cash, Cash Equivalents and the Capital Stock of the Issuer or of any direct or
indirect parent corporation of the Issuer (and performs the related incidental
activities associated with such ownership) and complies with the requirements of
Rule 3-10 of Regulation S-X promulgated by the Commission (or any successor
provision), the reports, information and other documents required to be filed
and furnished to Holders pursuant to this Section 4.17 may, at the option of the
Issuer, be filed by and be those of Holdco rather than the Issuer.

            (d) Notwithstanding the foregoing, such requirements shall be deemed
satisfied prior to the commencement of the Registered Exchange Offer or the
effectiveness of the Shelf Registration Statement by the filing with the
Commission of the Exchange Offer Registration Statement and/or Shelf
Registration Statement, and any amendments thereto, with such financial
information that satisfies Regulation S-X of the Securities Act.

                                      -84-

<PAGE>

            If the Issuer has designated any of its Subsidiaries as Unrestricted
Subsidiaries and such Unrestricted Subsidiaries, either individually or
collectively, would otherwise have been a Significant Subsidiary, then the
quarterly and annual financial information required by this Section 4.17 shall
include a reasonably detailed presentation, either on the face of the financial
statements or in the footnotes to the financial statements and in Management's
Discussion and Analysis of Results of Operations and Financial Condition, of the
financial condition and results of operations of the Issuer and the Restricted
Subsidiaries of the Issuer.

SECTION 4.18. Limitation on Layering.

            The Issuer will not, and will not permit any Restricted Subsidiary
that is a Guarantor to, directly or indirectly, incur any Indebtedness that is
or purports to be by its terms (or by the terms of any agreement governing such
Indebtedness) contractually subordinated or junior in right of payment to any
Senior Debt (including Acquired Debt) of the Issuer or Guarantor Senior Debt
(including Acquired Debt) of such Restricted Subsidiary, as the case may be,
unless such Indebtedness is either

            (1) pari passu in right of payment with the Securities or the
      Guarantees; or

            (2) subordinate in right of payment to the Securities or the
      Guarantees.

            For purposes of the foregoing, no Indebtedness will be deemed to be
contractually subordinated or junior in right of payment to any other
Indebtedness solely by virtue of being unsecured or by virtue of the fact that
the holders of Secured Indebtedness have entered into intercreditor or similar
arrangements giving one or more of such holders priority over the other holders
in the collateral held by them.

SECTION 4.19. Business Activities.

            The Issuer will not, and will not permit any Restricted Subsidiary
to, engage in any business other than Permitted Businesses, except to such
extent as would not be material to the Issuer and its Subsidiaries taken as a
whole.

SECTION 4.20. Payments for Consent.

            The Issuer will not, and will not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration to or for the
benefit of any Holder for or as an inducement to any consent, waiver or
amendment of any of the terms or provisions of this Indenture or the Securities
unless such consideration is offered to be paid and 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 or agreement.

SECTION 5.01. Merger, Consolidation, or Sale of Assets.

            (a) The Issuer may not, directly or indirectly: (1) consolidate or
merge with or into another Person (whether or not the Issuer is the surviving
corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all
or substantially all of the properties or assets of the Issuer and its
Subsidiaries, taken as a whole, in one or more related transactions, to another
Person, unless:

            (1) either: (a) the Issuer is the surviving corporation; or (b) the
      Person formed by or surviving any such consolidation or merger (if other
      than the Issuer) or to which such sale, assignment, transfer, conveyance
      or other disposition has been made is a corporation organized or existing
      under the laws of the United States, any state of the United States, the
      District of Columbia or any territory thereof (the Issuer or such Person,
      as the case may be, being herein called the "SUCCESSOR COMPANY");

            (2) the Successor Company (if other than the Issuer) assumes all the
      obligations of the Issuer under the Securities, this Indenture and the
      Registration Rights Agreement pursuant to agreements reasonably
      satisfactory to the Trustee;

            (3) immediately after such transaction no Default or Event of
      Default exists;

            (4) immediately after giving pro forma effect to such transaction
      and any related financing transactions, as if the same had occurred at the
      beginning of the applicable four-quarter period, either

                  (a) the Successor Company would be permitted to incur at least
            $1.00 of additional Indebtedness pursuant to the Coverage Ratio
            Exception; or

                  (b) the Fixed Charge Coverage Ratio for the Successor Company
            and its Restricted Subsidiaries would be greater than such ratio for
            the Issuer and its Restricted Subsidiaries immediately prior to such
            transaction; and

            (5) each Guarantor, unless it is the other party to the transactions
      described above, shall have by supplemental indenture confirmed that its
      Guarantee shall apply to such Person's obligations under this Indenture
      and the Securities.

                                      -86-

            For purposes of this Section 5.01, the sale, lease, conveyance,
assignment, transfer or other disposition of all or substantially all of the
properties and assets of one or more Subsidiaries of the Issuer, which
properties and assets, if held by the Issuer instead of such Subsidiaries, would
constitute all or substantially all of the properties and assets of the Issuer
on a consolidated basis, shall be deemed to be the transfer of all or
substantially all of the properties and assets of the Issuer.

            The predecessor company will be released from its obligations under
this Indenture and the Successor Company will succeed to, and be substituted
for, and may exercise every right and power of, the Issuer under this Indenture,
but, in the case of a lease of all or substantially all its assets, the
predecessor will not be released from the obligation to pay the principal of and
interest on the Securities.

            This Section 5.01 will not apply to a sale, assignment, transfer,
conveyance or other disposition of assets between or among the Issuer and its
Restricted Subsidiaries. Notwithstanding the foregoing clauses (3) and (4), (i)
any Restricted Subsidiary may consolidate with, merge into or transfer all or
part of its properties and assets to the Issuer and (ii) the Issuer may merge
with an Affiliate incorporated solely for the purpose of reincorporating the
Issuer in another state of the United States to realize tax benefits so long as
the amount of Indebtedness of the Issuer and its Restricted Subsidiaries is not
increased thereby. Notwithstanding anything to the contrary in this Indenture,
the merger of UGS Corp. into UGS PLM Solutions Inc. shall be permitted.

            (b) The Issuer will deliver to the Trustee prior to the consummation
of each proposed transaction an Officers' Certificate certifying that the
conditions set forth above are satisfied and an Opinion of Counsel, which
opinion may contain customary exceptions and qualifications, that the proposed
transaction and the supplemental indenture, if any, comply with this Indenture.

      redemption, acceleration or otherwise, of principal of, or premium, if

      (other than Indebtedness owed to the Issuer or a Restricted Subsidiary),
      whether such Indebtedness or guarantee now exists or is created after the
      Issue Date, if (A) such default either (1) results from the failure to pay
      any such Indebtedness at its stated final maturity (after giving effect to
      any applicable grace periods) or (2) relates to an obligation other than
      the obligation to pay principal of any such Indebtedness at its stated
      final maturity and results in the holder or holders of such Indebtedness
      causing such Indebtedness to become due prior to its stated maturity and
      (B) the principal amount of such Indebtedness, together with the principal
      amount of any other such Indebtedness in default for failure to pay

                  (G) takes any corporate action to authorize or effect any of
            the foregoing;

            (6) a court of competent jurisdiction enters an order or decree
      under any Bankruptcy Law that:

                  (A) is for relief against the Issuer or any Significant
            Subsidiary in an involuntary case,

                  (B) appoints a Custodian of the Issuer or any Significant

      final judgments (other than any judgments covered by insurance policies
      issued by reputable and creditworthy insurance companies) aggregating in
      excess of $20.0 million, which final judgments remain unpaid, undischarged
      and unstayed for a period of more than 60 days after such judgment becomes
      final, and, with respect to any such judgments covered by insurance, an
      enforcement proceeding has been commenced by any creditor upon such
      judgment or decree which is not promptly stayed; or

            (8) the Guarantee of a Significant Subsidiary or any group of
      Subsidiaries that, taken together as of the date of the most recent
      audited financial statements of the Issuer, would constitute a Significant
      Subsidiary ceases to be in full force and effect (except as contemplated
      by the terms hereof) or any Guarantor denies or disaffirms its obligations
      under this Indenture or any Guarantee other than by reason of the release
      of the Guarantee in accordance with this Indenture and such Default
      continues for 10 days.

SECTION 6.02. Acceleration.

            If an Event of Default specified in Sections 6.01(5) and (6) above
occurs with respect to the Issuer and is continuing, then all unpaid principal
of, and premium, if any, and accrued and unpaid interest on all of the
outstanding Securities shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder.

                                      -89-
<PAGE>

            If any other Event of Default shall occur and be continuing, the
Trustee or the Holders of at least 25% in principal amount of outstanding
Securities under this Indenture may declare the principal of and accrued
interest on such Securities to be due and payable by notice in writing to the
Issuer and the Trustee specifying the respective Event of Default and that it is
a "notice of acceleration" (the "ACCELERATION NOTICE"), and the same shall
become immediately due and payable upon the first to occur of an acceleration
under the Credit Agreement and five Business Days after receipt by the Issuer
and the Representative under the Credit Agreement of such Acceleration Notice
but only if such Event of Default is then continuing.

            At any time after a declaration of acceleration with respect to the
Securities as described in the two preceding paragraphs, the Holders of a
majority in principal amount of the Securities may rescind and cancel such
declaration and its consequences:

            (1) if the rescission would not conflict with any judgment or
      decree;

            (2) if all existing Events of Default have been cured or waived
      except nonpayment of principal or interest that has become due solely
      because of the acceleration;

            (3) to the extent the payment of such interest is lawful, if
      interest on overdue installments of interest and overdue principal, which
      has become due otherwise than by such declaration of acceleration, has
      been paid;

            (4) if the Issuer has paid the Trustee its reasonable compensation
      and reimbursed the Trustee for its expenses, disbursements and advances;
      and

            (5) in the event of the cure or waiver of an Event of Default of the
      type described in Sections 6.01(5) and (6), if the Trustee shall have
      received an Officers' Certificate and an Opinion of Counsel that such
      Event of Default has been cured or waived.

No such rescission shall affect any subsequent Default or impair any right
consequent thereto.

SECTION 6.03. Other Remedies.

            (a) If a Default occurs and is continuing, the Trustee may pursue
any available remedy by proceeding at law or in equity to collect the payment of
principal of or interest on the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

            (b) The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by

                                      -90-
<PAGE>

the Trustee or any Securityholder in exercising any right or remedy accruing
upon a Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Default. No remedy is exclusive of any other remedy. All
available remedies are cumulative to the extent permitted by law.

            (c) In the event of any Event of Default specified in clause (4) of
Section 6.01, such Event of Default and all consequences thereof (excluding,
however, any resulting payment default) will be annulled, waived and rescinded,
automatically and without any action by the Trustee or the Holders, if within 20
days after such Event of Default arose the Issuer delivers an Officers'
Certificate to the Trustee stating that (x) the Indebtedness or guarantee that
is the basis for such Event of Default has been discharged or (y) the holders
thereof have rescinded or waived the acceleration, notice or action (as the case
may be) giving rise to such Event of Default or (z) the default that is the
basis for such Event of Default has been cured.

            (d) Holders may not enforce this Indenture or the Securities except
as provided in this Indenture and under the TIA. Subject to the provisions of
this Indenture relating to the duties of the Trustee, the Trustee is under no
obligation to exercise any of its rights or powers under this Indenture at the
request, order or direction of any of the Holders, unless such Holders have
offered to the Trustee reasonable indemnity.

SECTION 6.04. Waiver of Defaults.

            Provided the Securities are not then due and payable by reason of a
declaration of acceleration, the Holders of a majority in aggregate principal
amount of Securities at the time outstanding may on behalf of the Holders of all
the Securities waive any Default with respect to such Securities and its
consequences by providing written notice thereof to the Issuer and the Trustee,
except a Default (1) in the payment of interest on or the principal of any
Security or (2) in respect of a covenant or provision hereof which under this
Indenture cannot be modified or amended without the consent of the Holder of
each outstanding Security affected. In the case of any such waiver, the Issuer,
the Trustee and the Holders will be restored to their former positions and
rights under this Indenture, respectively; provided that no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereto.

SECTION 6.05. Control by Majority.

            The Holders of not less than a majority in principal amount of the
outstanding Securities may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on it. Subject to Section 7.01, however, the Trustee may refuse
to follow any direction that conflicts with any law or this Indenture, that the
Trustee determines may be unduly prejudicial to the rights of another
Securityholder, or that may involve the Trustee in personal liability; provided
that the

                                      -91-
<PAGE>

Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.

            In the event the Trustee takes any action or follows any direction
pursuant to this Indenture, the Trustee shall be entitled to indemnification
against any loss or expense caused by taking such action or following such
direction.

SECTION 6.06. Limitation on Suits.

            A Holder may not pursue any remedy with respect to this Indenture or
the Securities unless:

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

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

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

            (4) the Trustee does not comply with the request within 45 days
      after receipt of the request and the offer and the provision of indemnity;
      and

            (5) during such 45-day period the Holder or Holders of a majority in
      principal amount of the outstanding Securities do not give the Trustee a
      direction which, in the opinion of the Trustee, is inconsistent with the
      request.

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

SECTION 6.07. Rights of Holders To Receive Payment.

            Notwithstanding any other provision of this Indenture, the right of
any Holder to receive payment of principal of and interest on a Security, on or
after the respective due dates expressed in such Security, 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 the Holder.

SECTION 6.08. Collection Suit by Trustee.

            If a Default in payment of principal or interest specified in
Section 6.01(1) or (2) occurs and is continuing, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Issuer
or any other obligor on the Securities for the whole

                                      -92-
<PAGE>

amount of principal and accrued interest and fees remaining unpaid, together
with interest on overdue principal and, to the extent that payment of such
interest is lawful, interest on overdue installments of interest, in each case
at the rate per annum borne by the Securities 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 may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel) and the Holders allowed in any
judicial proceedings relating to the Issuer, its creditors or its property and
shall be entitled and empowered to collect and receive any monies or other
property payable or deliverable on any such claims and to distribute the same,
and any Custodian in any such judicial proceedings 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 compensation, expenses, disbursements
and advances of the Trustee, its agent and counsel, and any other amounts due
the Trustee under Section 7.07. 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 Securities or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such
proceeding. The Trustee shall be entitled to participate as a member of any
official committee of creditors in the matters as it deems necessary or
advisable.

SECTION 6.10. Priorities.

            Subject to the provisions of Article Ten, if the Trustee collects
any money or property pursuant to this Article Six, it shall pay out the money
or property in the following order:

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

            SECOND: to Holders for interest accrued on the Securities, ratably,

            FOURTH: to the Issuer or, if applicable, the Guarantors, as their
      respective interests may appear.

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 Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 6.07, or a suit by a Holder or Holders of more than
10% in principal amount of the outstanding Securities.

SECTION 7.01. Duties of Trustee.

            (a) If a 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 their exercise as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs.

            (b) Except during the continuance of a Default:

            (1) The Trustee need perform only those duties as are specifically
      set forth herein or in the TIA and no duties, covenants, responsibilities
      or obligations shall be implied in this Indenture against the Trustee.

            (2) In the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon certificates (including Officers'
      Certificates) or opinions (including Opinions of Counsel) furnished to the
      Trustee and conforming to the requirements of this Indenture. However, in
      the case of any such certificates or opinions which by any provision
      hereof are specifically required to be furnished to the Trustee, the
      Trustee

                                      -94-
<PAGE>

      shall examine the certificates and opinions to determine whether or not
      they conform to the requirements of this Indenture.

            (c) Notwithstanding anything to the contrary herein, the Trustee may
not be relieved from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that:

            (1) This paragraph does not limit the effect of paragraph (b) of
      this Section 7.01.

            (2) The Trustee shall not be liable for any error of judgment made
      in good faith by a Responsible Officer, unless it is proved that the
      Trustee was negligent in ascertaining the pertinent facts.

            (3) The Trustee shall not be liable with respect to any action it
      takes or omits to take in good faith in accordance with a direction
      received by it pursuant to Section 6.05.

            (d) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or take any action at the request or direction of Holders
if it shall have reasonable grounds for believing that repayment of such funds
is not assured to it.

            (e) Whether or not therein expressly so provided, every provision of
this Indenture that in any way relates to the Trustee is subject to this Section
7.01.

            (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Issuer. Money
held in trust by the Trustee need not be segregated from other funds except to
the extent required by law.

            (g) In the absence of bad faith, negligence or willful misconduct on
the part of the Trustee, the Trustee shall not be responsible for the
application of any money by any Paying Agent other than the Trustee.

SECTION 7.02. Rights of Trustee.

            Subject to Section 7.01:

            (a) The Trustee may rely conclusively on any document believed by it
      to be genuine and to have been signed or presented by the proper Person.
      The Trustee need not investigate any fact or matter stated in the
      document.

                                      -95-
<PAGE>

            (b) Before the Trustee acts or refrains from acting, it may require
      an Officers' Certificate and an Opinion of Counsel, which shall conform to
      the provisions of Section 12.05. The Trustee shall not be liable for any
      action it takes or omits to take in good faith in reliance on such
      certificate or opinion.

            (c) The Trustee may act through its attorneys and agents and shall
      not be responsible for the misconduct or negligence of any agent (other
      than an agent who is an employee of the Trustee) appointed with due care.

            (d) The Trustee shall not be liable for any action it takes or omits
      to take in good faith which it reasonably believes to be authorized or
      within its rights or powers.

            (e) The Trustee may consult with counsel of its selection and the
      advice or opinion of such counsel as to matters of law shall be full and
      complete authorization and protection from liability in respect of any
      action taken, omitted or suffered by it hereunder in good faith and in
      accordance with the advice or opinion of such counsel.

            (f) The Trustee shall be under no obligation to exercise any of the
      rights or powers vested in it by this Indenture at the request, order or
      direction of any of the Holders pursuant to the provisions of this
      Indenture, unless such Holders shall have offered to the Trustee
      reasonable security or indemnity satisfactory to it against the costs,
      expenses and liabilities which may be incurred therein or thereby.

            (g) The Trustee shall not be bound to make any investigation into
      the facts or matters stated in any resolution, certificate (including any
      Officers' Certificate), statement, instrument, opinion (including any
      Opinion of Counsel), notice, request, direction, consent, order, bond,
      debenture, or other paper or document, but the Trustee, in its discretion,
      may make such further inquiry or investigation into such facts or matters
      as it may see fit and, if the Trustee shall determine to make such further
      inquiry or investigation, it shall be entitled, upon reasonable notice to
      the Issuer, to examine the books, records, and premises of the Issuer,
      personally or by agent or attorney at the sole cost of the Issuer.

            (h) The Trustee shall not be required to give any bond or surety in
      respect of the performance of its powers and duties hereunder.

            (i) The permissive rights of the Trustee to do things enumerated in
      this Indenture shall not be construed as duties.

            (j) Except with respect to Section 4.01, the Trustee shall have no
      duty to inquire as to the performance of the Issuer with respect to the
      covenants contained in Article Four. In addition, the Trustee shall not be
      deemed to have knowledge of an Event of Default except (i) any Default or
      Event of Default occurring pursuant to

                                      -96-
<PAGE>

      Sections 4.01, 6.01(1) or 6.01(2) or (ii) any Default or Event of Default
      of which the Trustee shall have received written notification or obtained
      actual knowledge.

            (k) The rights, privileges, protections, immunities and benefits
      given to the Trustee, including, without limitation, its right to be
      indemnified, are extended to, and shall be enforceable by, the Trustee in
      each of its capacities hereunder, and to each agent, custodian and other
      Person employed to act hereunder.

            (l) Delivery of reports, information and documents to the Trustee
      under Section 4.17 is for informational purposes only and the Trustee's
      receipt of the foregoing shall not constitute constructive notice of any
      information contained therein or determinable from information contained
      therein, including the Issuer's compliance with any of its covenants
      hereunder (as to which the Trustee is entitled to rely exclusively on
      Officers' Certificate.

SECTION 7.03. Individual Rights of Trustee.

            The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Issuer, its
Subsidiaries or their respective Affiliates with the same rights it would have
if it were not Trustee. Any Agent may do the same with like rights. However, the
Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04. Trustee's Disclaimer.

            The Trustee shall not be responsible for and makes no representation
as to the validity or adequacy of this Indenture or the Securities, it shall not
be accountable for the Issuer's use of the proceeds from the Securities, and it
shall not be responsible for any statement of the Issuer in this Indenture or
any document issued in connection with the sale of Securities or any statement
in the Securities other than the Trustee's certificate of authentication. The
Trustee makes no representations with respect to the effectiveness or adequacy
of this Indenture.

SECTION 7.05. Notice of Default.

            If a Default occurs and is continuing and the Trustee receives
actual notice of such Default, the Trustee shall mail to each Holder notice of
the uncured Default within 60 days after such Default occurs. Except in the case
of a Default in payment of principal of, or interest on, any Security, including
an accelerated payment and the failure to make payment on the Change of Control
Payment Date pursuant to a Change of Control Offer or the Asset Sale Payment
Date pursuant to an Asset Sale Offer, the Trustee may withhold the notice if and
so long as the Board of Directors, the executive committee, or a trust committee
of

                                      -97-
<PAGE>

directors and/or Responsible Officers, of the Trustee in good faith determines
that withholding the notice is in the interest of the Holders.

SECTION 7.06. Reports by Trustee to Holders.

            Within 60 days after each May 15, beginning with May 15, 2005, the
Trustee shall, to the extent that any of the events described in TIA Section
313(a) occurred within the previous twelve months, but not otherwise, mail to
each Holder a brief report dated as of such date that complies with TIA Section
313(a). The Trustee also shall comply with TIA Sections 313(b), 313(c) and
313(d).

            A copy of each report at the time of its mailing to Holders shall be
mailed to the Issuer and filed with the Commission and each securities exchange,
if any, on which the Securities are listed.

            The Issuer shall notify the Trustee if the Securities become listed
on any securities exchange or of any delisting thereof and the Trustee shall
comply with TIA Section 313(d).

SECTION 7.07. Compensation and Indemnity.

            The Issuer shall pay to the Trustee from time to time such
compensation as the Issuer and the Trustee shall from time to time agree in
writing for its services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Issuer
shall reimburse the Trustee upon request for all reasonable disbursements,
expenses and advances (including reasonable fees and expenses of counsel)
incurred or made by it in addition to the compensation for its services, except
any such disbursements, expenses and advances as may be attributable to the
Trustee's negligence, bad faith or willful misconduct. Such expenses shall
include the reasonable fees and expenses of the Trustee's agents and counsel.

            The Issuer shall indemnify each of the Trustee or any predecessor
Trustee and its agents, employees, officers, stockholders and directors for, and
hold them harmless against, any and all loss, damage, claims including taxes
(other than taxes based upon, measured by or determined by the income of the
Trustee), liability or expense incurred by them except for such actions to the
extent caused by any negligence, bad faith or willful misconduct on their part,
arising out of or in connection with the acceptance or administration of this
trust including the costs and expenses of enforcing this Indenture or a
Guarantee against the Issuer or a Guarantor (including this Section 7.07) and
the reasonable costs and expenses of defending themselves against or
investigating any claim or liability in connection with the exercise or
performance of any of the Trustee's rights, powers or duties hereunder (whether
asserted by the Issuer, any Guarantor, any Holder or any other Person). The
Trustee shall notify the Issuer promptly of any claim asserted against the
Trustee or any of its agents,

                                      -98-
<PAGE>

employees, officers, stockholders and directors for which it may seek indemnity.
The Issuer may, subject to the approval of the Trustee (which approval shall not
be unreasonably withheld), defend the claim and the Trustee shall cooperate in
the defense. The Trustee and its agents, employees, officers, stockholders and
directors subject to the claim may have separate counsel and the Issuer shall
pay the reasonable fees and expenses of such counsel; provided, however, that
the Issuer will not be required to pay such fees and expenses if, subject to the
approval of the Trustee (which approval shall not be unreasonably withheld), it
assumes the Trustee's defense and there is no conflict of interest between the
Issuer and the Trustee and its agents, employees, officers, stockholders and
directors subject to the claim in connection with such defense as reasonably
determined by the Trustee. The Issuer need not pay for any settlement made
without its written consent. The Issuer need not reimburse any expense or
indemnify against any loss or liability to the extent incurred by the Trustee
through its negligence, bad faith or willful misconduct.

            To secure the Issuer's and the Guarantors' payment obligations in
this Section 7.07, the Trustee shall have a Lien prior to the Securities against
all money or property held or collected by the Trustee, in its capacity as
Trustee. The obligations of the Issuer and the Guarantors to the Trustee under
this Section shall not be subordinated to the payment of Senior Debt pursuant to
Article Ten or Section 11.02 except assets or money held in trust to pay
principal of or interest on particular Securities (with the exception of
Permitted Junior Securities and trusts established pursuant to Article Eight).

            When the Trustee incurs expenses or renders services after a Default
specified in Section 6.01(5) or (6) occurs, such expenses and the compensation
for such services shall be paid to the extent allowed under any Bankruptcy Law
and are intended to constitute expenses of administration under any Bankruptcy
Law.

            Notwithstanding any other provision in this Indenture, the foregoing
provisions of this Section 7.07 shall survive the satisfaction and discharge of
this Indenture or the appointment of a successor Trustee.

SECTION 7.08. Replacement of Trustee.

            The Trustee may resign at any time by so notifying the Issuer in
writing. The Holders of a majority in principal amount of the outstanding
Securities may remove the Trustee by so notifying the Issuer and the Trustee and
may appoint a successor Trustee. The Issuer may remove the Trustee if:

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

            (2) the Trustee is adjudged a bankrupt or an insolvent;

                                      -99-
<PAGE>

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

            (4) the Trustee becomes incapable of acting.

            If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Issuer shall notify each Holder of such
event and 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 Securities may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuer.

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Issuer. Immediately after that,
the retiring Trustee shall transfer, after payment of all sums then owing to the
Trustee pursuant to Section 7.07, all property held by it as Trustee to the
successor Trustee, subject to the Lien provided in Section 7.07, 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. A successor Trustee shall mail notice of its succession to each
Holder.

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

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

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

SECTION 7.09. Successor Trustee by Merger, Etc.

            If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the resulting, surviving or transferee corporation without any
further act shall, if such resulting, surviving or transferee corporation is
otherwise eligible hereunder, be the successor Trustee; provided that such
corporation shall be otherwise qualified and eligible under this Article Seven.

SECTION 7.10. Eligibility; Disqualification.

            This Indenture shall always have a Trustee who satisfies the
requirement of TIA Sections 310(a)(1), 310(a)(2) and 310(a)(5). The Trustee
shall have a combined capital and

                                     -100-
<PAGE>

surplus of at least $150,000,000 as set forth in its most recent published
annual report of condition. In addition, if the Trustee is a corporation
included in a bank holding company system, the Trustee, independently of the
bank holding company, shall meet the capital requirements of TIA Section
310(a)(2). The Trustee shall comply with TIA Section 310(b); provided, however,
that there shall be excluded from the operation of TIA Section 310(b)(1) any
indenture or indentures under which other securities, or certificates of
interest or participation in other securities, of the Issuer are outstanding, if
the requirements for such exclusion set forth in TIA Section 310(b)(1) are met.
The provisions of TIA Section 310 shall apply to the Issuer and any other
obligor of the Securities.

SECTION 7.11. Preferential Collection of Claims Against the Issuer.

            The Trustee, in its capacity as Trustee hereunder, shall comply with
TIA Section 311(a), excluding any creditor relationship listed in TIA Section
311(b). A Trustee who has resigned or been removed shall be subject to TIA
Section 311(a) to the extent indicated.

      benefit of the Holders of that purpose, U.S. Legal Tender, non-callable
      U.S. Government Securities, or a combination thereof, in amounts as is, in
      the opinion of a nationally recognized firm of independent public
      accountants, sufficient without consideration of reinvestment of such
      interest, to pay and discharge the entire Indebtedness on the Securities
      not delivered to the Trustee for cancellation for principal, premium, if
      any, and Additional Interest, if any, and accrued interest on the
      outstanding Securities to maturity or redemption; provided that the
      Trustee shall have been irrevocably instructed to apply such U.S. Legal
      Tender or U.S. Government Securities, or a combination thereof, to the
      payment of said principal, premium, if any, and interest with respect to
      the Securities; and provided, further, that from and after the time of
      deposit, the U.S. Legal Tender or U.S. Government Securities, or
      combination thereof, deposited shall not be subject to the rights of
      holders of Senior Debt pursuant to the provisions of Article Ten;

            (c) no Default or Event of Default with respect to this Indenture or
      the Securities shall have occurred and be continuing on the date of such
      deposit or shall occur as a result of such deposit (other than a Default
      resulting from borrowing of funds to be applied to such deposit and the
      grant of any Lien securing such borrowing) and such deposit will not
      result in a breach or violation of, or constitute a default under, any
      material instrument to which the Issuer is a party or by which it is
      bound;

            (d) the Issuer shall have paid all other sums payable by it
      hereunder; and

            (e) the Issuer shall have delivered irrevocable instructions to the
      Trustee under this Indenture to apply the deposited money toward the
      payment of the Securities at maturity or the Redemption Date, as the case
      may be.

Certificate and an Opinion of Counsel, each stating that all conditions
precedent providing for or relating to the termination of the Issuer's
obligations under the Securities and this Indenture have been complied with.
Such Opinion of Counsel shall also state that such satisfaction and discharge
does not result in a default under the Credit Agreement or any other material
agreement or instrument then known to such counsel that binds or affects the
Issuer.

            Subject to the next sentence and notwithstanding the foregoing
paragraph, the Issuer's obligations in Sections 2.05, 2.06, 2.07, 2.08, 4.01,
4.02, 7.07, 8.05 and 8.06 shall survive until the Securities are no longer
outstanding pursuant to the last paragraph of Section 2.08. After the Securities
are no longer outstanding, the Issuer's obligations in Sections 7.07, 8.05 and
8.06 shall survive.

                                     -102-
<PAGE>

            After such delivery or irrevocable deposit, the Trustee upon request
shall acknowledge in writing the discharge of the Issuer's obligations under the
Securities and this Indenture except for those surviving obligations specified
above.

SECTION 8.02. Legal Defeasance and Covenant Defeasance.

            (a) The Issuer may, at its option and at any time, elect to have
either paragraph (b) or (c) below applied to all outstanding Securities upon
compliance with the conditions set forth in Section 8.03.

            (b) Upon the Issuer's exercise under paragraph (a) hereof of the
option applicable to this paragraph (b), the Issuer and the Guarantors shall,
subject to the satisfaction of the conditions set forth in Section 8.03, be
deemed to have been discharged from their obligations with respect to all
outstanding Securities on the date the conditions set forth below are satisfied
(hereinafter, "LEGAL DEFEASANCE"). For this purpose, Legal Defeasance means that
the Issuer shall be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Securities, which shall thereafter be deemed to
be "outstanding" only for the purposes of Section 8.04 hereof and the other
Sections of this Indenture (with respect to such Securities) referred to in (i)
and (ii) below, and to have satisfied all its other obligations under such
Securities and this Indenture (with respect to such Securities) and the
Guarantors shall be deemed to have satisfied all of their obligations under the
Guarantees and this Indenture (and the Trustee, on demand of and at the expense
of the Issuer, shall execute proper instruments acknowledging the same), except
for the following provisions which shall survive until otherwise terminated or
discharged hereunder:

            (i) the rights of Holders of outstanding Securities issued hereunder
      to receive payments in respect of the principal of, or interest or premium
      and Additional Interest, if any, on such Securities when such payments are
      due from the trust referred to below;

            (ii) the Issuer's obligations with respect to the Securities issued
      hereunder concerning issuing temporary Securities, registration of
      Securities, mutilated, destroyed, lost or stolen Securities and the
      maintenance of an office or agency for payment and money for security
      payments held in trust;

            (iii) the rights, powers, trusts, duties and immunities of the
      Trustee, and the Issuer's obligations in connection therewith; and

            (iv) this Article Eight.

            Subject to compliance with this Article Eight, the Issuer may
exercise its option under this Section 8.02(b) notwithstanding the prior
exercise of its option under Section 8.02(c) hereof.

                                     -103-
<PAGE>

            (c) Upon the Issuer's exercise under paragraph (a) hereof of the
option applicable to this paragraph (c), the Issuer and the Guarantors shall,
subject to the satisfaction of the conditions set forth in Section 8.03 hereof,
be released from their obligations under the covenants contained in Sections
4.04, 4.05, 4.06, 4.07 and 4.09 through 4.20 and clause (4) of Section 5.01(a)
hereof with respect to the outstanding Securities on and after the date the
conditions set forth in Section 8.03 are satisfied (hereinafter, "COVENANT
DEFEASANCE"), and the Securities shall thereafter be deemed not "outstanding"
for the purposes of any direction, waiver, consent or declaration or act of
Holders (and the consequences of any thereof) in connection with such covenants,
but shall continue to be deemed "outstanding" for all other purposes hereunder
(it being understood that such Securities shall not be deemed outstanding for
accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Securities, the Issuer 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 covenant to any other provision herein or in any other document and
such omission to comply shall not constitute an Event of Default under Section
6.01 hereof, but, except as specified above, the remainder of this Indenture and
such Securities shall be unaffected thereby. In addition, upon the Issuer's
exercise under paragraph (a) hereof of the option applicable to this paragraph
(c), subject to the satisfaction of the conditions set forth in Section 8.03
hereof, clauses (3), (4), (5) (with respect to a Significant Subsidiary), (6)
(with respect to a Significant Subsidiary) and (7) of Section 6.01 hereof shall
not constitute Events of Default.

SECTION 8.03. Conditions to Legal Defeasance or Covenant Defeasance.

            The following shall be the conditions to the application of either
Section 8.02(b) or 8.02(c) hereof to the outstanding Securities:

            In order to exercise either Legal Defeasance or Covenant Defeasance:

            (1) the Issuer must irrevocably deposit with the Trustee, in trust,
      for the benefit of the holders of the applicable Securities issued
      hereunder, cash in U.S. Legal Tender, non-callable U.S. Government
      Securities, or a combination thereof, in amounts as will be sufficient, in
      the opinion of a nationally recognized firm of independent public
      accountants, to pay the principal of, or interest and premium and
      Additional Interest, if any, on the outstanding Securities issued
      hereunder on the Stated Maturity or on the applicable Redemption Date, as
      the case may be, and the Issuer must specify whether the Securities are
      being defeased to maturity or to a particular Redemption Date;

            (2) in the case of an election under Section 8.02(b) hereof, the
      Issuer has delivered to the Trustee an Opinion of Counsel reasonably
      acceptable to the Trustee confirming that (a) the Issuer has received
      from, or there has been published by, the

                                     -104-
<PAGE>

      Internal Revenue Service a ruling or (b) since the date of this Indenture,
      there has been a change in the applicable federal income tax law, in
      either case to the effect that, and based thereon such Opinion of Counsel
      will confirm that, the holders of the respective outstanding Securities
      will not recognize income, gain or loss for federal income tax purposes as
      a result of such Legal Defeasance and will be subject to federal income
      tax on the same amounts, in the same manner and at the same times as would
      have been the case if such Legal Defeasance had not occurred;

            (3) in the case of an election under Section 8.02(c) hereof, the
      Issuer has delivered to the Trustee an Opinion of Counsel reasonably
      acceptable to the Trustee confirming that the holders of the respective
      outstanding Securities will not recognize income, gain or loss for federal
      income tax purposes as a result of such Covenant Defeasance and will be
      subject to federal income tax on the same amounts, in the same manner and
      at the same times as would have been the case if such Covenant Defeasance
      had not occurred;

            (4) no Default or Event of Default has occurred and is continuing on
      the date of such deposit (other than a Default or Event of Default
      resulting from the borrowing of funds to be applied to such deposit and
      the grant of any Lien securing such borrowings) or insofar as Events of
      Default resulting from the borrowing of funds or insolvency events are
      concerned, at any time in the period ending on the 91st day after the date
      of deposit;

            (5) such Legal Defeasance or Covenant Defeasance will not result in
      a breach or violation of, or constitute a default under any material
      agreement or instrument (other than this Indenture) to which the Issuer or
      any of its Restricted Subsidiaries is a party or by which the Issuer or
      any of its Restricted Subsidiaries is bound;

            (6) the Issuer must deliver to the Trustee an Officers' Certificate
      stating that the deposit was not made by the Issuer with the intent of
      defeating, hindering, delaying or defrauding creditors of the Issuer or
      others; and

            (7) the Issuer must deliver to the Trustee an Officers' Certificate
      and an Opinion of Counsel, each stating that all conditions precedent
      relating to the Legal Defeasance or the Covenant Defeasance have been
      complied with.

SECTION 8.04. Application of Trust Money.

            The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or
U.S. Government Securities, deposited with it pursuant to this Article Eight,
and shall apply the deposited U.S. Legal Tender or the money from U.S.
Government Securities, in accordance with this Indenture to the payment of
principal of and interest on the Securities. The Trustee

                                     -105-
<PAGE>

shall be under no obligation to invest said U.S. Legal Tender or U.S. Government
Securities, except as it may agree with the Issuer.

            The Issuer shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the U.S. Legal Tender or U.S.
Government Securities, deposited pursuant to Section 8.03 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding
Securities.

            Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Issuer from time to time upon the Issuer's
request any U.S. Legal Tender or U.S. Government Securities, held by it as
provided in Section 8.03 which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, 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 8.05. Repayment to the Issuer.

            Subject to this Article Eight, the Trustee and the Paying Agent
shall promptly pay to the Issuer upon request any excess U.S. Legal Tender or
U.S. Government Securities, held by them at any time and thereupon shall be
relieved from all liability with respect to such money. The Trustee and the
Paying Agent shall pay to the Issuer upon request any money held by them for the
payment of principal or interest that remains unclaimed for two years; provided
that the Trustee or such Paying Agent, before being required to make any
payment, may at the expense of the Issuer cause to be published once in a
newspaper of general circulation in the City of New York or mail to each Holder
entitled to such money notice that such money remains unclaimed and that after a
date specified therein which shall be at least 30 days from the date of such
publication or mailing any unclaimed balance of such money then remaining will
be repaid to the Issuer. After payment to the Issuer, Holders entitled to such
money must look to the Issuer for payment as general creditors unless an
applicable law designates another Person.

SECTION 8.06. Reinstatement.

            If the Trustee or Paying Agent is unable to apply any U.S. Legal
Tender or U.S. Government Securities, in accordance with this Article Eight by
reason of any legal proceeding or by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, the Issuer's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Eight until such time as the Trustee or Paying Agent is
permitted to apply all such U.S. Legal Tender and U.S. Government Securities, in
accordance with this Article Eight; provided that if the Issuer has made any
payment of interest on or

                                     -106-
<PAGE>

principal of any Securities because of the reinstatement of its obligations, the
Issuer shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the U.S. Legal Tender or U.S. Government Securities,
held by the Trustee or Paying Agent.

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01. Without Consent of Holders.

            Subject to Section 9.03, without the consent of any Holder, the

the Securities:

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

            (2) to provide for uncertificated Securities in addition to or in
      place of certificated Securities;

            (3) to provide for the assumption of the Issuer's obligations to

      substantially all of the Issuer's assets;

            (4) to make any change that would provide any additional rights or
      benefits to the Holders or that does not adversely affect the legal rights
      under this Indenture of any Holder;

            (5) to secure the Securities;

            (6) to comply with requirements of the Commission in order to effect

            (7) to add a Guarantee of the Securities, including, without
      limitation, by Holdco; or

            (8) to release a Guarantor upon its sale or designation as an
      Unrestricted Subsidiary or other permitted release from its Guarantee;
      provided that such sale, designation or release is in accordance with the
      applicable provisions of this Indenture;

provided that the Issuer has delivered to the Trustee an Opinion of Counsel and
an Officers' Certificate, each stating that such amendment or supplement
complies with the provisions of this Section 9.01.

                                     -107-
<PAGE>

SECTION 9.02. With Consent of Holders.

            (a) Subject to Sections 6.07 and 9.03, the Issuer, the Guarantors
and the Trustee, together, with the written consent of the Holder or Holders of
at least a majority in aggregate principal amount of the outstanding Securities
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, Securities), may amend or supplement
this Indenture or the Securities without notice to any other Holders. Subject to
Sections 6.07 and 9.03, the Holder or Holders of a majority in aggregate
principal amount of then outstanding Securities may waive compliance with any
provision of this Indenture or the Securities (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Securities) without notice to any other Holders (except a default in
respect of the payment of principal or interest on the Securities).

            (b) Notwithstanding Section 9.02(a), without the consent of each
Holder affected, an amendment, supplement or waiver, including a waiver pursuant
to Section 6.04, may not (with respect to any Securities held by a
non-consenting Holder):

            (1) reduce the principal amount of Securities whose Holders must
      consent to an amendment, supplement or waiver;

            (2) reduce the principal of or change the fixed maturity of any
      Security or alter the provisions with respect to the redemption of the
      Securities (other than provisions of Sections 4.09 and 4.13);

            (3) reduce the rate of or change the time for payment of interest on
      any Security;

            (4) waive a Default or Event of Default in the payment of principal,
      or interest or premium, or Additional Interest, if any, on the Securities
      (except a rescission of acceleration of the Securities by the Holders of
      at least a majority in aggregate principal amount of the Securities with
      respect to a nonpayment default and a waiver of the payment default that
      resulted from such acceleration);

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

            (6) make any change in the provisions of this Indenture relating to
      waivers of past Defaults or the rights of Holders to receive payments of
      principal of, or interest or premium or Additional Interest, if any, on
      the Securities;

            (7) waive a redemption payment with respect to any Security (other
      than a payment required by one of the provisions of Section 4.09 or
      Section 4.13;

                                     -108-
<PAGE>

            (8) make any change in the preceding amendment and waiver
      provisions; or

            (9) modify the Guarantees in any manner adverse to the Holders.

            (c) It shall not be necessary for the consent of the Holders under
this Section to approve the particular form of any proposed amendment,
supplement 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 Issuer shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Issuer to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amendment, supplement or
waiver.

SECTION 9.03. Effect on Senior Debt.

            No amendment of, or supplement or waiver to, this Indenture shall
adversely affect the rights of any holder of Senior Debt under the subordination
provisions of this Indenture (including without limitation the provisions of
Article Ten and Section 11.02 hereof) and the defined terms as used therein
without the consent of such holder or its Representative.

SECTION 9.04. Compliance with TIA.

            From the date on which this Indenture is qualified under the TIA,
every amendment, waiver or supplement of this Indenture, the Securities or the
Subsidiary Guarantees shall comply with the TIA as then in effect.

SECTION 9.05. Revocation and Effect of Consents.

            (a) Until an amendment, waiver or supplement becomes effective, a
consent to it by a Holder is a continuing consent by the Holder and every
subsequent Holder of a Security or portion of a Security that evidences the same
debt as the consenting Holder's Security, even if notation of the consent is not
made on any Security. However, any such Holder or subsequent Holder may revoke
the consent as to his Security or portion of his Security by notice to the
Trustee or the Issuer received before the date on which the Trustee receives an
Officers' Certificate certifying that the Holders of the requisite principal
amount of Securities have consented (and not theretofore revoked such consent)
to the amendment, supplement or waiver.

            (b) The Issuer may, but shall not be obligated to, fix a Record Date
for the purpose of determining the Holders entitled to consent to any amendment,
supplement or

                                     -109-
<PAGE>

waiver which record date shall be at least 30 days prior to the first
solicitation of such consent. If a record date is fixed, then notwithstanding
the last sentence of the immediately preceding paragraph, those Persons who were
Securityholders at such Record Date (or their duly designated proxies), and only
those Persons, shall be entitled to revoke any consent previously given, whether
or not such Persons continue to be Holders after such Record Date. No such
consent shall be valid or effective for more than 90 days after such Record
Date. The Issuer shall inform the Trustee in writing of the fixed Record Date if
applicable.

            (c) After an amendment, supplement or waiver becomes effective, it
shall bind every Securityholder, unless it makes a change described in any of
clauses (1) through (9) of Section 9.02(b), in which case, the amendment,
supplement or waiver shall bind only each Holder of a Security who has consented
to it and every subsequent Holder of a Security or portion of a Security that
evidences the same debt as the consenting Holder's Security; provided that any
such waiver shall not impair or affect the right of any Holder to receive
payment of principal of and interest on a Security, on or after the respective
due dates expressed in such Security, or to bring suit for the enforcement of
any such payment on or after such respective dates without the consent of such
Holder.

SECTION 9.06. Notation on or Exchange of Securities.

            If an amendment, supplement or waiver changes the terms of a
Security, the Issuer may require the Holder of the Security to deliver it to the
Trustee. The Issuer shall provide the Trustee with an appropriate notation on
the Security about the changed terms and cause the Trustee to return it to the
Holder at the Issuer's expense. Alternatively, if the Issuer or the Trustee so
determines, the Issuer in exchange for the Security shall issue and the Trustee
shall authenticate a new Security that reflects the changed terms. Failure to
make the appropriate notation or issue a new Security shall not affect the
validity and effect of such amendment, supplement or waiver.

SECTION 9.07. Trustee To Sign Amendments, Etc.

            The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article Nine; provided that the Trustee may, but
shall not be obligated to, execute any such amendment, supplement or waiver
which affects the Trustee's own rights, duties or immunities under this
Indenture. The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel and an Officers' Certificate
each stating that the execution of any amendment, supplement or waiver
authorized pursuant to this Article Nine is authorized or permitted by this
Indenture and constitutes the legal, valid and binding obligations of the Issuer
enforceable in accordance with its terms. Such Opinion of Counsel shall be at
the expense of the Issuer.

                                  ARTICLE TEN

                           SUBORDINATION OF SECURITIES

SECTION 10.01. Securities Subordinated to Senior Debt.

            Anything herein to the contrary notwithstanding, the Issuer, for
itself and its successors, and each Holder, by his or her acceptance of
Securities, agrees that the payment of all Obligations owing to the Holders in
respect of the Securities is subordinated, to the extent and in the manner
provided in this Article Ten, to the prior payment in full in cash or Cash
Equivalents, or such payment duly provided for to the satisfaction of the
holders of Senior Debt, of all Obligations on Senior Debt (including the
Obligations with respect to the Credit Agreement, whether outstanding on the
Issue Date or thereafter incurred). Notwithstanding the foregoing, payments and
distributions made relating to the Securities from the trust established
pursuant to Article Eight shall not be so subordinated in right of payment, so
long as the conditions specified in Article Eight (without any waiver or
modification of the requirement that the deposits pursuant thereto do not
conflict with the terms of the Credit Agreement or any other Senior Debt) are
satisfied on the date of any deposit pursuant to said trust.

            This Article Ten shall constitute a continuing offer to all Persons
who become holders of, or continue to hold, Senior Debt, and such provisions are
made for the benefit of the holders of Senior Debt and such holders are made
obligees hereunder and any one or more of them may enforce such provisions.

SECTION 10.02. Suspension of Payment When Designated Senior Debt Is in Default.

            (a) If any default occurs and is continuing when payment is due,
whether at maturity, upon any redemption, by declaration or otherwise, of any
principal of, interest on, unpaid drawings for letters of credit issued in
respect of, or fees or other amounts payable with respect to, any Designated
Senior Debt (a "PAYMENT DEFAULT"), then no payment or distribution of any kind
or character shall be made by or on behalf of the Issuer or any other Person on
its or their behalf with respect to any Obligations on or relating to the
Securities or to acquire, defease or redeem any of the Securities for cash or
assets or otherwise unless the default has been cured or waived; provided,
however, that the Issuer may pay the Securities without regard to the foregoing
if the Issuer and the Trustee receive written notice approving such payment from
the Representative of the holders of such Designated Senior Debt.

            (b) If any other event of default (other than a Payment Default)
occurs and is continuing with respect to any Designated Senior Debt (as such
event of default is defined in the instrument creating or evidencing such
Designated Senior Debt) permitting the holders of such Designated Senior Debt
then outstanding to accelerate the maturity thereof (a "NON-

                                     -111-
<PAGE>

PAYMENT DEFAULT") and if the Representative for the respective issue of
Designated Senior Debt gives notice of the event of default to the Trustee
stating that such notice is a payment blockage notice (a "PAYMENT BLOCKAGE
NOTICE"), then during the period (the "PAYMENT BLOCKAGE PERIOD") beginning upon
the delivery of such Payment Blockage Notice and ending on the earlier of the
179th day after such delivery and the date on which (x) such Nonpayment Default
with respect to such Designated Senior Debt has been cured or waived or ceases
to exist, (y) all Designated Senior Debt with respect to which any such event of
default has occurred and is continuing is discharged or paid in full in cash or
Cash Equivalents, or (z) the Trustee receives notice thereof from the
Representative for the respective issue of Designated Senior Debt terminating
the Payment Blockage Period (unless the maturity of any Designated Senior Debt
has been accelerated or a Payment Default exists), neither the Issuer nor any
other Person on its behalf shall (x) make any payment of any kind or character
with respect to any Obligations on or with respect to the Securities or (y)
acquire, defease or redeem any of the Securities for cash or assets or
otherwise. Notwithstanding anything herein to the contrary, (x) in no event will
a Payment Blockage Period extend beyond 179 days from the date the applicable
Payment Blockage Notice is received by the Trustee and (y) only one such Payment
Blockage Period may be commenced within any 360 consecutive days. For all
purposes of this Section 10.02(b), no event of default which existed or was
continuing on the date of the commencement of any Payment Blockage Period with
respect to the Designated Senior Debt shall be, or be made, the basis for the
commencement of a second Payment Blockage Period by the Representative of such
Designated Senior Debt whether or not within a period of 360 consecutive days,
unless such event of default shall have been cured or waived for a period of not
less than 90 consecutive days (it being acknowledged that any subsequent action,
or any breach of any financial covenants for a period ending after the date of
commencement of such Payment Blockage Period that, in either case, would give
rise to an event of default pursuant to any provisions under which an event of
default previously existed or was continuing shall constitute a new event of
default for this purpose).

            (c) The foregoing Sections 10.02(a) and (b) shall not apply to
payments and distributions made relating to the Securities from the trust
established pursuant to Article Eight, so long as the conditions specified in
Article Eight (without any waiver or modification of the requirement that the
deposits pursuant thereto do not conflict with the terms of the Credit Agreement
or any other Senior Debt) are satisfied on the date of any deposit pursuant to
said trust. In addition, Holders may also receive and retain Permitted Junior
Securities.

            (d) In the event that, notwithstanding the foregoing, any payment or
distribution shall be received by the Trustee or any Holder when such payment or
distribution is prohibited by the foregoing provisions of this Section 10.02,
such payment or distribution shall be held in trust for the benefit of, and
shall be paid over or delivered to, the holders of Senior Debt (pro rata to such
holders on the basis of the respective amount of Senior Debt held by such
holders) or their respective Representatives, as their respective interests may
appear. The Trustee shall be entitled to rely on information regarding amounts
then due and

                                     -112-
<PAGE>

owing on the Senior Debt, if any, received from the holders of Senior Debt (or
their Representatives) or, if such information is not received from such holders
or their Representatives, from the Issuer and only amounts included in the
information provided to the Trustee shall be paid to the holders of Senior Debt.

            Nothing contained in this Article Ten shall limit the right of the
Trustee or the Holders of Securities to take any action to accelerate the
maturity of the Securities pursuant to Section 6.02 or to pursue any rights or
remedies hereunder; provided that all Senior Debt thereafter due or declared to
be due shall first be paid in full in cash or Cash Equivalents before the
Holders are entitled to receive any payment of any kind or character with
respect to Obligations on the Securities (and such Holders may receive such
payments only to the extent then permitted to do so by Section 10.02(a) and
(b)).

SECTION 10.03. Securities Subordinated to Prior Payment of All Senior Debt on
               Dissolution, Liquidation or Reorganization of the Issuer.

            (a) Upon any payment or distribution of assets of the Issuer of any
kind or character, whether in cash, assets or securities, to creditors upon any
total or partial liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling of assets and liabilities
of the Issuer or in a bankruptcy, reorganization, insolvency, receivership or
other similar proceeding relating to the Issuer or its assets, whether voluntary
or involuntary, all Obligations due or to become due upon all Senior Debt shall
first be paid in full in cash or Cash Equivalents, or such payment duly provided
for to the satisfaction of the holders of Senior Debt, before any payment or
distribution of any kind or character is made on account of any Obligations on
or relating to the Securities (except that Holders may receive and retain
Permitted Junior Securities and payments from the trusts described in Article
Eight), or for the acquisition, defeasance or redemption of any of the
Securities for cash or assets or otherwise. Upon any such dissolution,
winding-up, liquidation, reorganization, receivership or similar proceeding, any
payment or distribution of assets of the Issuer of any kind or character,
whether in cash, assets or securities, to which the Holders or the Trustee under
this Indenture would be entitled, except for the provisions hereof, shall be
paid by the Issuer or by any receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making such payment or distribution, or by the
Holders or by the Trustee under this Indenture if received by them, directly to
the holders of Senior Debt (pro rata to such holders on the basis of the
respective amounts of Senior Debt held by such holders) or their respective
Representatives, or to the trustee or trustees under any indenture pursuant to
which any of such Senior Debt may have been issued, as their respective
interests may appear, for application to the payment of Senior Debt remaining
unpaid until all such Senior Debt has been paid in full in cash or Cash
Equivalents after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of Senior Debt.

                                     -113-
<PAGE>

            (b) To the extent any payment of Senior Debt (whether by or on
behalf of the Issuer, as proceeds of security or enforcement of any right of
setoff or otherwise) is declared to be fraudulent or preferential, set aside or
required to be paid to any receiver, trustee in bankruptcy, liquidating trustee,
agent or other similar Person under any bankruptcy, insolvency, receivership,
fraudulent conveyance or similar law, then the Senior Debt or part thereof
originally intended to be satisfied shall be deemed to be reinstated and
outstanding as if such payment had not occurred.

            It is further agreed that any diminution (whether pursuant to court
decree or otherwise, including without limitation for any of the reasons
described in the preceding sentence) of the Issuer's obligation to make any
distribution or payment pursuant to any Senior Debt, except to the extent such
diminution occurs by reason of the repayment (which has not been disgorged or
returned) of such Senior Debt in cash or Cash Equivalents, shall have no force
or effect for purposes of the subordination provisions contained in this Article
Ten, with any turnover of payments as otherwise calculated pursuant to this
Article Ten to be made as if no such diminution had occurred.

            (c) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Issuer of any kind or character, whether in cash,
assets or securities, shall be received by the Trustee or any Holder when such
payment or distribution is prohibited by this Section 10.03, such payment or
distribution shall be held in trust for the benefit of, and shall be paid over
or delivered to, the holders of Senior Debt (pro rata to such holders on the
basis of the respective amount of Senior Debt held by such holders) or their
respective Representatives, or to the trustee or trustees under any indenture
pursuant to which any of such Senior Debt may have been issued, as their
respective interests may appear, for application to the payment of Senior Debt
remaining unpaid until all such Senior Debt has been paid in full in cash or
Cash Equivalents, after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of such Senior Debt.

            (d) The consolidation of the Issuer with, or the merger of the
Issuer with or into, another corporation, partnership, trust or limited
liability company or the liquidation or dissolution of the Issuer following the
conveyance or transfer of all or substantially all of its assets, to another
corporation, partnership, trust or limited liability company upon the terms and
conditions provided in Article Five hereof and as long as permitted under the
terms of the Senior Debt shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section if such other
corporation shall, as a part of such consolidation, merger, conveyance or
transfer, assume the Issuer's obligations hereunder in accordance with Article
Five hereof.

SECTION 10.04. Payments May Be Made Prior to Dissolution.

            Nothing contained in this Article Ten or elsewhere in this Indenture
shall prevent (i) the Issuer, except under the conditions described in Sections
10.02 and 10.03, from

                                     -114-
<PAGE>

making payments at any time for the purpose of making payments of principal of
and interest on the Securities, or from depositing with the Trustee any moneys
for such payments, or (ii) in the absence of actual knowledge by the Trustee
that a given payment would be prohibited by Section 10.02 or 10.03, the
application by the Trustee of any moneys deposited with it for the purpose of
making such payments of principal of, and interest on, the Securities to the
Holders entitled thereto unless at least two Business Days prior to the date
upon which such payment would otherwise become due and payable a Responsible
Officer of the Trustee shall have actually received the written notice provided
for in the first sentence of Section 10.02(b) or in Section 10.07 (provided
that, notwithstanding the foregoing, the Holders receiving any payments made in
contravention of Section 10.02 and/or 10.03 (and the respective such payments)
shall otherwise be subject to the provisions of Section 10.02 and Section
10.03). The Issuer shall give prompt written notice to the Trustee of any
dissolution, winding-up, liquidation or reorganization of the Issuer, although
any delay or failure to give any such notice shall have no effect on the
subordination provisions contained herein.

SECTION 10.05. Holders To Be Subrogated to Rights of Holders of Senior Debt.

            Subject to the payment in full in cash or Cash Equivalents of all
Senior Debt, the Holders of the Securities shall be subrogated to the rights of
the holders of Senior Debt to receive payments or distributions of cash, assets
or securities of the Issuer applicable to the Senior Debt until the Securities
shall be paid in full; and, for the purposes of such subrogation, no such
payments or distributions to the holders of the Senior Debt by or on behalf of
the Issuer, or by or on behalf of the Holders by virtue of this Article Ten,
which otherwise would have been made to the Holders shall, as between the Issuer
and the Holders, be deemed to be a payment by the Issuer to or on account of the
Senior Debt, it being understood that the provisions of this Article Ten are and
are intended solely for the purpose of defining the relative rights of the
Holders, on the one hand, and the holders of Senior Debt, on the other hand.

SECTION 10.06. Obligations of the Issuer Unconditional.

            Nothing contained in this Article Ten or elsewhere in this Indenture
or in the Securities is intended to or shall impair, as among the Issuer, its
creditors other than the holders of Senior Debt, and the Holders, the obligation
of the Issuer, which is absolute and unconditional, to pay to the Holders the
principal of and any interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders and creditors of the Issuer
other than the holders of the Senior Debt, nor shall anything herein or therein
prevent the Holder of any Security or the Trustee on its behalf from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, in respect of cash, assets or
securities of the Issuer received upon the exercise of any such remedy.

                                     -115-
<PAGE>

SECTION 10.07. Notice to Trustee.

            The Issuer shall give prompt written notice to the Trustee of any
fact known to the Issuer which would prohibit the making of any payment to or by
the Trustee in respect of the Securities pursuant to the provisions of this
Article Ten, although any delay or failure to give any such notice shall have no
effect on the subordination provisions contained herein. Regardless of anything
to the contrary contained in this Article Ten or elsewhere in this Indenture,
the Trustee shall not be charged with knowledge of the existence of any default
or event of default with respect to any Senior Debt or of any other facts which
would prohibit the making of any payment to or by the Trustee unless and until
the Trustee shall have received notice in writing from the Issuer, or from a
holder of Senior Debt or a Representative therefor and, prior to the receipt of
any such written notice, the Trustee shall be entitled to assume (in the absence
of actual knowledge to the contrary) that no such facts exist. The Trustee shall
be entitled to rely on the delivery to it of any notice pursuant to this Section
10.07 to establish that such notice has been given by a holder of Senior Debt
(or a trustee thereof).

            In the event that the Trustee determines in good faith that any
evidence is required with respect to the right of any Person as a holder of
Senior Debt to participate in any payment or distribution pursuant to this
Article Ten, the Trustee may request such Person to furnish evidence to the
satisfaction of the Trustee as to the amounts of Senior Debt held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article Ten, and if such evidence is not furnished the Trustee
may defer any payment to such Person pending judicial determination as to the
right of such Person to receive such payment.

SECTION 10.08. Reliance on Judicial Order or Certificate of Liquidating Agent.

            Upon any payment or distribution of assets of the Issuer referred to
in this Article Ten, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders of the Securities shall be entitled to rely upon any
order or decree made by any court of competent jurisdiction in which any
insolvency, bankruptcy, receivership, dissolution, winding-up, liquidation,
reorganization or similar case or proceeding is pending, or upon a certificate
of the receiver, trustee in bankruptcy, liquidating trustee, assignee for the
benefit of creditors, agent or other person making such payment or distribution,
delivered to the Trustee or the Holders, for the purpose of ascertaining the
persons entitled to participate in such payment or distribution, the holders of
the Senior Debt and other Indebtedness of the Issuer, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Ten.

SECTION 10.09. Trustee's Relation to Senior Debt.

            The Trustee and any agent of the Issuer or the Trustee shall be
entitled to all the rights set forth in this Article Ten with respect to any
Senior Debt which may at any time

                                     -116-
<PAGE>

be held by it in its individual or any other capacity to the same extent as any
other holder of Senior Debt and nothing in this Indenture shall deprive the
Trustee or any such agent of any of its rights as such holder.

            With respect to the holders of Senior Debt, the Trustee undertakes
to perform or to observe only such of its covenants and obligations as are
specifically set forth in this Article Ten, and no implied covenants or
obligations with respect to the holders of Senior Debt 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 Debt.

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

SECTION 10.10. Subordination Rights Not Impaired by Acts or
               Omissions of the Issuer or Holders of Senior Debt.

            No right of any present or future holders of any Senior Debt to
enforce subordination as provided herein shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Issuer or
by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Issuer with the terms of this Indenture, regardless of any
knowledge thereof which any such holder may have or otherwise be charged with.

            Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Debt may, at any time and from time to time,
without the consent of or notice to the Trustee, without incurring
responsibility to the Trustee or the Holders and without impairing or releasing
the subordination provided in this Article Ten or the obligations hereunder of
the Holders to the holders of the Senior Debt, do any one or more of the
following: (i) change the manner, place or terms of payment or extend the time
of payment of, or renew or alter, Senior Debt, or otherwise amend or supplement
in any manner Senior Debt, or any instrument evidencing the same or any
agreement under which Senior Debt is outstanding; (ii) sell, exchange, release
or otherwise deal with any property pledged, mortgaged or otherwise securing
Senior Debt; (iii) release any Person liable in any manner for the payment or
collection of Senior Debt; and (iv) exercise or refrain from exercising any
rights against the Issuer and any other Person.

SECTION 10.11. Securityholders Authorize Trustee To Effectuate Subordination of
               Securities.

            Each Holder by its acceptance of Securities authorizes and expressly
directs the Trustee on its behalf to take such action as may be necessary or
appropriate to effectuate, as between the holders of Senior Debt and the
Holders, the subordination provided in this

                                     -117-
<PAGE>

Article Ten, and appoints the Trustee its attorney-in-fact for such purposes,
including, in the event of any dissolution, winding-up, liquidation or
reorganization of the Issuer (whether in bankruptcy, insolvency, receivership,
reorganization or similar proceedings or upon an assignment for the benefit of
credits or otherwise) tending towards liquidation of the business and assets of
the Issuer, the filing of a claim for the unpaid balance of its Securities and
accrued interest in the form required in those proceedings.

            If the Trustee does not file a proper claim or proof of debt in the
form required in such proceeding prior to 30 days before the expiration of the
time to file such claim or claims, then the holders of the Senior Debt or their
Representative are or is hereby authorized to have the right to file and are or
is hereby authorized to file an appropriate claim for and on behalf of the
Holders of said Securities. Nothing herein contained shall be deemed to
authorize the Trustee or the holders of Senior Debt or their Representative to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee or the holders
of Senior Debt or their Representative to vote in respect of the claim of any
Holder in any such proceeding.

SECTION 10.12. This Article Ten Not To Prevent Events of Default.

            The failure to make a payment on account of principal of, premium,
if any, or interest on the Securities by reason of any provision of this Article
Ten will not be construed as preventing the occurrence of an Event of Default.

SECTION 10.13. Trustee's Compensation Not Prejudiced.

            Nothing in this Article Ten will apply to amounts due to the Trustee
for its own account (other than payments of Obligations owing to Holders in
respect of Securities) pursuant to other sections of this Indenture.

                                 ARTICLE ELEVEN

                                   GUARANTEES

SECTION 11.01. Unconditional Guarantee.

            Subject to the provisions of this Article Eleven, each of the
Guarantors hereby, jointly and severally, unconditionally and irrevocably
guarantees, as a primary obligor and not merely as a surety, on a senior
subordinated basis to each Holder of a Security authenticated and delivered by
the Trustee and to the Trustee and its successors and assigns, irrespective of
the validity and enforceability of this Indenture, the Securities or the
obligations of the Issuer

                                     -118-
<PAGE>

or any other Guarantors to the Holders or the Trustee hereunder or thereunder:
(a) (x) the due and punctual payment of the principal of, premium, if any, and
interest on the Securities when and as the same shall become due and payable,
whether at maturity, upon redemption or repurchase, by acceleration or
otherwise, (y) the due and punctual payment of interest on the overdue principal
and (to the extent permitted by law) interest, if any, on the Securities
(including, without limitation, interest accruing after the filing of any
petition in bankruptcy, or the commencement of any insolvency, reorganization or
like proceeding relating to the Issuer or any Guarantor, whether or not a claim
for post-filing or post-petition interest is allowed in such proceeding) and (z)
the due and punctual payment and performance of all other obligations of the
Issuer and all other obligations of the other Guarantors (including under the
Guarantees), in each case, to the Holders or the Trustee hereunder or thereunder
(including amounts due the Trustee under Section 7.07 hereof), all in accordance
with the terms hereof and thereof (collectively, the "GUARANTEE OBLIGATIONS");
and (b) in case of any extension of time of payment or renewal of any Securities
or any of such other obligations, the due and punctual payment and performance
of Guarantee Obligations in accordance with the terms of the extension or
renewal, whether at maturity, upon redemption or repurchase, by acceleration or
otherwise. Failing payment when due of any amount so guaranteed, or failing
performance of any other obligation of the Issuer to the Holders under this
Indenture or under the Securities, for whatever reason, each Guarantor shall be
obligated to pay, or to perform or cause the performance of, the same
immediately. An Event of Default under this Indenture or the Securities shall
constitute an event of default under the Guarantees, and shall entitle the
Holders to accelerate the obligations of the Guarantors thereunder in the same
manner and to the same extent as the obligations of the Issuer.

            Each of the Guarantors hereby agrees that its obligations hereunder
shall be unconditional, irrespective of the validity, regularity or
enforceability of the Securities or this Indenture, the absence of any action to
enforce the same, any waiver or consent by any Holder with respect to any
provisions hereof or thereof, any release of any other Guarantor, the recovery
of any judgment against the Issuer, any action to enforce the same, whether or
not a Guarantee is affixed to any particular Security, or any other circumstance
which might otherwise constitute a legal or equitable discharge or defense of a
Guarantor. Each of the Guarantors hereby waives the benefit of diligence,
presentment, demand of payment, filing of claims with a court in the event of
insolvency or bankruptcy of the Issuer, any right to require a proceeding first
against the Issuer, protest, notice and all demands whatsoever and covenants
that its Guarantee shall not be discharged except by complete performance of the
obligations contained in the Securities, this Indenture and the Guarantee. The
Guarantee is a guarantee of payment and not of collection. If any Holder or the
Trustee is required by any court or otherwise to return to the Issuer or to any
Guarantor, or any custodian, trustee, liquidator or other similar official
acting in relation to the Issuer or such Guarantor, any amount paid by the
Issuer or such Guarantor to the Trustee or such Holder, the Guarantee, to the
extent theretofore discharged, shall be reinstated in full force and effect.
Each Guarantor further agrees that, as between it, on the one hand, and the
Holders of Securities and the

                                     -119-
<PAGE>

Trustee, on the other hand, (a) subject to this Article Eleven, the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article Six
for the purposes of the Guarantee, notwithstanding any stay, injunction or other
prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (b) in the event of any acceleration of such obligations
as provided in Article Six hereof, such obligations (whether or not due and
payable) shall forthwith become due and payable by the Guarantors for the
purpose of the Guarantee.

SECTION 11.02. Subordination of Guarantee.

            The obligations of each Guarantor under its Guarantee pursuant to
this Article Eleven shall be junior and subordinated to the prior payment in
full in cash or Cash Equivalents of Guarantor Senior Debt on the same basis as
the Securities are junior and subordinated to Senior Debt of the Issuer. For the
purposes of the foregoing sentence, the Trustee and the Holders shall have the
right to receive and/or retain payments by any of the Guarantors only at such
times as they may receive and/or retain payments in respect of the Securities
pursuant to this Indenture, including Article Ten hereof.

SECTION 11.03. Limitation on Guarantor Liability.

            Each Guarantor, and by its acceptance of Securities, each Holder,
hereby confirms that it is the intention of all such parties that the Guarantee
of such Guarantor not constitute a fraudulent transfer or conveyance for
purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform
Fraudulent Transfer Act or any similar federal or state law to the extent
applicable to any Guarantee. To effectuate the foregoing intention, the Trustee,
the Holders and the Guarantors hereby irrevocably agree that the obligations of
such Guarantor under its Guarantee and this Article Eleven shall be limited to
the maximum amount as will, after giving effect to such maximum amount and all
other contingent and fixed liabilities of such Guarantor that are relevant under
such laws, and after giving effect to any collections from rights to receive
contribution from or payments made by or on behalf of any other Guarantor in
respect of the obligations of such other Guarantor under this Article Eleven,
result in the obligations of such Guarantor under its Guarantee not constituting
a fraudulent transfer or conveyance.

SECTION 11.04. Execution and Delivery of Guarantee for Future Guarantors.

            To further evidence its Guarantee set forth in Section 11.01, each
Restricted Subsidiary that is required to become a Guarantor hereby agrees to
execute a supplement to this Indenture or a Guarantee, substantially in the form
of Exhibit G hereto, and deliver it to the Trustee. Such Guarantee or supplement
to this Indenture shall be executed on behalf of each Guarantor by either manual
or facsimile signature of one Officer or other person duly

                                     -120-
<PAGE>

authorized by all necessary corporate action of each Guarantor who shall have
been duly authorized to so execute by all requisite corporate action. The
validity and enforceability of any Guarantee shall not be affected by the fact
that it is not affixed to any particular Security.

            Each of the Guarantors hereby agrees that its Guarantee set forth in
Section 11.01 shall remain in full force and effect notwithstanding any failure
to endorse on each Security a notation of such Guarantee.

            If an Officer of a Guarantor whose signature is on this Indenture or
a Guarantee no longer holds that office at the time the Trustee authenticates
the Security on which such Guarantee is endorsed or at any time thereafter, such
Guarantor's Guarantee of such Security shall nevertheless be valid.

            The delivery of any Security by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of any Guarantee
set forth in this Indenture on behalf of each Guarantor.

SECTION 11.05. Release of a Guarantor.

            (a) The Guarantee of a Guarantor will be released:

            (1) (a) upon the sale, disposition or other transfer (including
      through merger or consolidation) of all of the Capital Stock (or any sale,
      disposition or other transfer of Capital Stock following which the
      applicable Guarantor is no longer a Restricted Subsidiary), or all or
      substantially all the assets, of the applicable Guarantor if such sale,
      disposition or other transfer is made in compliance with the applicable
      provisions of this Indenture,

            (b) if the Issuer designates any Restricted Subsidiary that is a
      Guarantor as an Unrestricted Subsidiary in accordance with Section 4.11
      and the definition of "Unrestricted Subsidiary," or

            (c) in the case of any Restricted Subsidiary which after the Issue
      Date is required to guarantee the Securities pursuant to Section 4.16,
      upon the release or discharge of the guarantee by such Restricted
      Subsidiary in the circumstances described in Section 4.16; and

            (2) in the case of clause (1)(a) above, if such Guarantor is
      released from its guarantee, if any, of, and all pledges and security, if
      any, granted in connection with, the Credit Agreement and any other
      Indebtedness of the Issuer or any Restricted Subsidiary;

                                     -121-
<PAGE>

provided, however, in any case that any such termination shall occur only to the
extent that none of the Equity Interests of such Guarantor are pledged for the
benefit of any holder of any Indebtedness of the Issuer or any Indebtedness of
any Restricted Subsidiary of the Issuer.

            The Trustee shall execute an appropriate instrument prepared by the
Issuer evidencing the release of a Guarantor from its obligations under its
Guarantee upon receipt of a request by the Issuer or such Guarantor accompanied
by an Officers' Certificate and an Opinion of Counsel certifying as to the
compliance with this Section 11.05; provided, however, that the legal counsel
delivering such Opinion of Counsel may rely as to matters of fact on one or more
Officers' Certificates of the Issuer.

            (b) In addition, the Issuer shall not permit any Guarantor to
consolidate with, merge with or into any person (other than the Issuer or
another Guarantor) and shall not permit the conveyance, transfer or lease of
substantially all of the assets of any Guarantor unless:

            (A)(1) either: (a) the Guarantor is the surviving Person; or (b) the
      Person formed by or surviving any such consolidation or merger (if other
      than the Guarantor) or to which such sale, assignment, transfer,
      conveyance or other disposition has been made is a corporation,
      partnership, trust or limited liability company organized and existing
      under the laws of the United States of America, any State of the United
      States of America or the District of Columbia (such Person being herein
      called the "Successor Guarantor");

            (2) the Successor Guarantor (if other than the Guarantor) assumes by
      means of a supplemental indenture all the obligations of the Guarantor
      under its Guarantee, the Indenture and the Registration Rights Agreement;
      and

      Default exists; or

another Guarantor or shall prevent any sale or conveyance of the property of a

SECTION 11.06. Waiver of Subrogation.

            Until this Indenture is discharged and all of the Securities are
discharged and paid in full, each Guarantor hereby irrevocably waives and agrees
not to exercise any claim or other rights which it may now or hereafter acquire
against the Issuer that arise from the existence, payment, performance or
enforcement of the Issuer's obligations under the Securities or this Indenture
and such Guarantor's obligations under the Guarantee and this Indenture, in any
such instance including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution, indemnification, and any right to
participate in any claim or remedy of the Holders against the Issuer, whether or
not such claim, remedy or right arises in equity, or under contract, statute or
common law, including, without limitation, the right to take or receive from the
Issuer, directly or indirectly, in cash or other assets or by set-off or in any
other manner, payment or security on account of such claim or other rights. If
any amount shall be paid to any Guarantor in violation of the preceding sentence
and any amounts owing to the Trustee or the Holders under the Securities, this
Indenture, or any other document or instrument delivered under or in connection
with such agreements or instruments, shall not have been paid in full, such
amount shall have been deemed to have been paid to such Guarantor for the
benefit of, and held in trust for the benefit of, the Trustee or the Holders and
shall forthwith be paid to the Trustee for the benefit of itself or such Holders
to be credited and applied to the obligations in favor of the Trustee or the
Holders, as the case may be, whether matured or unmatured, in accordance with
the terms of this Indenture. Each Guarantor acknowledges that it will receive
direct and indirect benefits from the financing arrangements contemplated by
this Indenture and that the waiver set forth in this Section 11.06 is knowingly
made in contemplation of such benefits.

SECTION 11.07. Immediate Payment.

            Each Guarantor agrees to make immediate payment to the Trustee on
behalf of the Holders of all Guarantee Obligations owing or payable to the
respective Holders upon receipt of a demand for payment therefor by the Trustee
to such Guarantor in writing.

SECTION 11.08. No Setoff.

            Each payment to be made by a Guarantor hereunder in respect of the
Guarantee Obligations shall be payable in the currency or currencies in which
such Guarantee Obligations are denominated, and shall be made without set-off,
counterclaim, reduction or diminution of any kind or nature.

SECTION 11.09. Guarantee Obligations Absolute.

            Subject to the provisions of Section 11.02, the obligations of each
Guarantor hereunder are and shall be absolute and unconditional and any monies
or amounts expressed to be owing or payable by each Guarantor hereunder which
may not be recoverable from such

                                     -123-
<PAGE>

Guarantor on the basis of a Guarantee shall be recoverable from such Guarantor
as a primary obligor and principal debtor in respect thereof.

SECTION 11.10. Guarantee Obligations Continuing.

            Subject to the other provisions of this Indenture, the obligations
of each Guarantor hereunder shall be continuing and shall remain in full force
and effect until all such obligations have been paid and satisfied in full. Each
Guarantor agrees with the Trustee that it will from time to time deliver to the
Trustee suitable acknowledgments of this continued liability hereunder and under
any other instrument or instruments in such form as counsel to the Trustee may
advise and as will prevent any action brought against it in respect of any
default hereunder being barred by any statute of limitations now or hereafter in
force and, in the event of the failure of a Guarantor so to do, it hereby
irrevocably appoints the Trustee the attorney and agent of such Guarantor to
make, execute and deliver such written acknowledgment or acknowledgments or
other instruments as may from time to time become necessary or advisable, in the
judgment of the Trustee on the advice of counsel, to fully maintain and keep in
force the liability of such Guarantor hereunder.

SECTION 11.11. Guarantee Obligations Not Reduced.

            The obligations of each Guarantor hereunder shall not be satisfied,
reduced or discharged solely by the payment of such principal, premium, if any,
interest, fees and other monies or amounts as may at any time prior to discharge
of this Indenture pursuant to Article Eight be or become owing or payable under
or by virtue of or otherwise in connection with the Securities or this
Indenture.

SECTION 11.12. Guarantee Obligations Reinstated.

            The obligations of each Guarantor hereunder shall continue to be
effective or shall be reinstated, as the case may be, if at any time any payment
which would otherwise have reduced the obligations of any Guarantor hereunder
(whether such payment shall have been made by or on behalf of the Issuer or by
or on behalf of a Guarantor) is rescinded or reclaimed from any of the Holders
upon the insolvency, bankruptcy, liquidation or reorganization of the Issuer or
any Guarantor or otherwise, all as though such payment had not been made. If
demand for, or acceleration of the time for, payment by the Issuer or any other
Guarantor is stayed upon the insolvency, bankruptcy, liquidation or
reorganization of the Issuer or such Guarantor, all such Indebtedness otherwise
subject to demand for payment or acceleration shall nonetheless be payable by
each Guarantor as provided herein.

SECTION 11.13. Guarantee Obligations Not Affected.

            The obligations of each Guarantor hereunder shall not be affected,
impaired or diminished in any way by any act, omission, matter or thing
whatsoever, occurring before,

                                     -124-
<PAGE>

upon or after any demand for payment hereunder (and whether or not known or
consented to by any Guarantor or any of the Holders) which, but for this
provision, might constitute a whole or partial defense to a claim against any
Guarantor hereunder or might operate to release or otherwise exonerate any
Guarantor from any of its obligations hereunder or otherwise affect such
obligations, whether occasioned by default of any of the Holders or otherwise,
including, without limitation:

            (a) any limitation of status or power, disability, incapacity or
      other circumstance relating to the Issuer or any other Person, including
      any insolvency, bankruptcy, liquidation, reorganization, readjustment,
      composition, dissolution, winding-up or other proceeding involving or
      affecting the Issuer or any other Person;

            (b) any irregularity, defect, unenforceability or invalidity in
      respect of any indebtedness or other obligation of the Issuer or any other
      Person under this Indenture, the Securities or any other document or
      instrument;

            (c) any failure of the Issuer or any other Guarantor, whether or not
      without fault on its part, to perform or comply with any of the provisions
      of this Indenture, the Securities or any Guarantee, or to give notice
      thereof to a Guarantor;

            (d) the taking or enforcing or exercising or the refusal or neglect
      to take or enforce or exercise any right or remedy from or against the
      Issuer or any other Person or their respective assets or the release or
      discharge of any such right or remedy;

            (e) the granting of time, renewals, extensions, compromises,
      concessions, waivers, releases, discharges and other indulgences to the
      Issuer or any other Person;

            (f) any change in the time, manner or place of payment of, or in any
      other term of, any of the Securities, or any other amendment, variation,
      supplement, replacement or waiver of, or any consent to departure from,
      any of the Securities or this Indenture, including, without limitation,
      any increase or decrease in the principal amount of or premium, if any, or
      interest on any of the Securities;

            (g) any change in the ownership, control, name, objects, businesses,
      assets, capital structure or constitution of the Issuer or a Guarantor;

            (h) any merger or amalgamation of the Issuer or a Guarantor with any
      Person or Persons;

            (i) the occurrence of any change in the laws, rules, regulations or
      ordinances of any jurisdiction by any present or future action of any
      governmental authority or court amending, varying, reducing or otherwise
      affecting, or purporting to

                                     -125-
<PAGE>

      amend, vary, reduce or otherwise affect, any of the Guarantee Obligations
      or the obligations of a Guarantor under its Guarantee; and

            (j) any other circumstance, including release of the Guarantor
      pursuant to Section 11.05 (other than by complete, irrevocable payment)
      that might otherwise constitute a legal or equitable discharge or defense
      of the Issuer under this Indenture or the Securities or of a Guarantor in
      respect of its Guarantee hereunder.

SECTION 11.14. Waiver.

            Without in any way limiting the provisions of Section 11.01, each
Guarantor hereby waives notice of acceptance hereof, notice of any liability of
any Guarantor hereunder, notice or proof of reliance by the Holders upon the
obligations of any Guarantor hereunder, and diligence, presentment, demand for
payment on the Issuer, protest, notice of dishonor or non-payment of any of the
Guarantee Obligations, or other notice or formalities to the Issuer or any
Guarantor of any kind whatsoever.

SECTION 11.15. No Obligation To Take Action Against the Issuer.

            Neither the Trustee nor any other Person shall have any obligation
to enforce or exhaust any rights or remedies against the Issuer or any other
Person or any property of the Issuer or any other Person before the Trustee is
entitled to demand payment and performance by any or all Guarantors of their
liabilities and obligations under their Guarantees or under this Indenture.

SECTION 11.16. Dealing with the Issuer and Others.

            The Holders, without releasing, discharging, limiting or otherwise
affecting in whole or in part the obligations and liabilities of any Guarantor
hereunder and without the consent of or notice to any Guarantor, may

            (a) grant time, renewals, extensions, compromises, concessions,
      waivers, releases, discharges and other indulgences to the Issuer or any
      other Person;

            (b) take or abstain from taking security or collateral from the
      Issuer or from perfecting security or collateral of the Issuer;

            (c) release, discharge, compromise, realize, enforce or otherwise

      matters contemplated by this Indenture or the Securities;

            (d) accept compromises or arrangements from the Issuer;

      any security upon such part of the Guarantee Obligations as the Holders
      may see fit or change any such application in whole or in part from time
      to time as the Holders may see fit; and

            (f) otherwise deal with, or waive or modify their right to deal
      with, the Issuer and all other Persons and any security as the Holders or
      the Trustee may see fit.

SECTION 11.17. Default and Enforcement.

            If any Guarantor fails to pay in accordance with Section 11.07
hereof, the Trustee may proceed in its name as trustee hereunder in the
enforcement of the Guarantee of any such Guarantor and such Guarantor's
obligations thereunder and hereunder by any remedy provided by law, whether by
legal proceedings or otherwise, and to recover from such Guarantor the
obligations.

SECTION 11.18. Amendment, Etc.

            No amendment, modification or waiver of any provision of this

of the Holders in enforcing any of their rights under any Guarantee.

SECTION 11.21. No Merger or Waiver; Cumulative Remedies.

            No Guarantee shall operate by way of merger of any of the
obligations of a Guarantor under any other agreement, including, without
limitation, this Indenture. No failure to exercise and no delay in exercising,
on the part of the Trustee or the Holders, any right, remedy, power or privilege
hereunder or under this Indenture or the Securities, shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder or under this Indenture or the Securities preclude any other
or

                                     -127-
<PAGE>

further exercise thereof or the exercise of any other right, remedy, power or
privilege. The rights, remedies, powers and privileges in the Guarantee and

of any of them.

SECTION 11.23. Severability.

            Any provision of this Article Eleven which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions
and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction
unless its removal would substantially defeat the basic intent, spirit and
purpose of this Indenture and this Article Eleven.

SECTION 11.24. Successors and Assigns.

            Each Guarantee shall be binding upon and inure to the benefit of
each Guarantor and the Trustee and the other Holders and their respective

[INSERT THE GLOBAL SECURITY LEGEND, IF APPLICABLE PURSUANT TO THE PROVISIONS OF
THE INDENTURE]

[INSERT THE PRIVATE PLACEMENT LEGEND, IF APPLICABLE PURSUANT TO THE PROVISIONS
OF THE INDENTURE]

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

            SECTION 1. Interest. UGS Corp., a Delaware corporation (the
"COMPANY"), promises to pay interest on the principal amount of this Security at
10% per annum from May 27, 2004 until maturity. The Company will pay interest
semi-annually on June 1 and December 1 of each year, or if any such day is not a
Business Day, on the next succeeding Business Day (each an "INTEREST PAYMENT
DATE"). Interest on the Securities will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from the date of
original issuance; provided that if there is no existing Default in the payment
of interest, and if this Security is authenticated between a record date
referred to on the face hereof and the next succeeding Interest Payment Date,
interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be December 1, 2004. 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 to the extent lawful at the interest rate applicable to the
Securities; it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace periods) from time to time on demand at
the same rate to the extent lawful. Interest will be computed on the basis of a
360-day year of twelve 30 day months.

            SECTION 2. Method of Payment. The Company will pay interest on the
Securities (except defaulted interest) to the Persons who are registered Holders
of Securities at the close of business on May 15 or November 15 next preceding
the Interest Payment Date, even if such Securities are canceled 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 Securities
will be issued in denominations of $1,000 and integral multiples of $1,000. The
Company shall pay principal, premium, if any and interest on the Securities 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 ("U.S. LEGAL TENDER").
The principal of (and premium, if any) and interest on the Securities shall be
payable at the office or agency of the Company maintained

                                      A-4
<PAGE>

for such purpose in the Borough of Manhattan, The City of New York, State of New
York, or at such other office or agency of the Company as may be maintained for
such purpose pursuant to Section 2.03 of the Indenture; provided, however, that,
at the option of the Company, each installment of interest may be paid by (i)
check mailed to addresses of the Persons entitled thereto as such addresses
shall appear on the registry maintained by the Registrar or (ii) wire transfer
to an account located in the United States maintained by the payee. Payments in
respect of Securities represented by a Global Security (including principal,
premium, if any, and interest) will be made by wire transfer of immediately
available funds to the accounts specified by DTC. Payments in respect of
Securities represented by Definitive Securities (including principal, premium,
if any, and interest) held by a Holder will be made by wire transfer to a U.S.
dollar account maintained by the payee with a bank in the United States if such
Holder elects payment by wire transfer by giving written notice to the Trustee
or the Paying Agent to such effect designating such account no later than three
Business Days immediately preceding the relevant due date for payment (or such
other date as the Trustee may accept in its discretion).

            SECTION 3. Paying Agent and Registrar. Initially, U.S. Bank National
Association, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any Affiliate may act in any such capacity.

            SECTION 4. Indenture. The Company issued the Securities under an
Indenture dated as of May 27, 2004 ("INDENTURE") among the Company, the
Guarantors and the Trustee. The terms of the Securities include those stated in
the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb) (the
"TIA"). The Securities are subject to all such terms, and Holders are referred
to the Indenture and the TIA for a statement of such terms. To the extent any
provision of this Security conflicts with the express provisions of the
Indenture, the provisions of the Indenture shall govern and be controlling.

            SECTION 5. Optional Redemption. (a) The Securities may be redeemed,
in whole or in part, at any time prior to June 1, 2008, at the option of the
Company upon not less than 30 nor more than 60 days' prior notice mailed by
first-class mail to each Holder's registered address, at a redemption price
equal to 100% of the principal amount of the Securities redeemed plus the
Applicable Premium as of, and accrued and unpaid interest and Additional
Interest, if any, to, the applicable redemption date (subject to the right of
Holders of record on the relevant record date to receive interest due on the
relevant Interest Payment Date).

            For purposes of the preceding paragraph, the following terms will
have the following definitions:

            "APPLICABLE PREMIUM" means, with respect to any Security on any
applicable redemption date, the greater of:

            (1) 1.0% of the then outstanding principal amount of the Security;
and

                                      A-5
<PAGE>

            (2) the excess of:

                  (a) the present value at such redemption date of (i) the
            redemption price of the Security at June 1, 2008 (such redemption
            price being set forth in the table appearing under paragraph (b))
            plus (ii) all required interest payments due on the Security through
            June 1, 2008 (excluding accrued but unpaid interest), computed using
            a discount rate equal to the Treasury Rate as of such redemption
            date plus 50 basis points; over

                  (b) the then outstanding principal amount of the Security.

            "TREASURY RATE" means, as of the applicable redemption date, the
yield to maturity as of such redemption date of United States Treasury
securities with a constant maturity (as compiled and published in the most
recent Federal Reserve Statistical Release H.15 (519) that has become publicly
available at least two Business Days prior to such redemption date (or, if such
Statistical Release is no longer published, any publicly available source of
similar market data)) most nearly equal to the period from such redemption date
to June 1, 2008; provided, however, that if the period from such redemption date
to June 1, 2008, is less than one year, the weekly average yield on actually
traded United States Treasury securities adjusted to a constant maturity of one
year will be used.

            (b) On or after June 1, 2008, the Securities will be subject to
redemption at any time at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest and Additional Interest thereon, if any, to the applicable
redemption date, if redeemed during the twelve-month period beginning on June 1
of the years indicated below:

<TABLE>

2009..................................          102.500%

</TABLE>

            SECTION 6. Optional Redemption upon Equity Offering. From time to
time prior to June 1, 2007, the Company may on any one or more occasions redeem
in the aggregate up to 35% of the aggregate principal amount of Securities
issued under the Indenture (calculated after giving effect to the issuance of
Additional Securities), with the net cash proceeds of one or more Equity
Offerings, at a redemption price equal to 110% of the principal amount thereof,
plus accrued and unpaid interest and Additional Interest thereon, if any, to the
redemption date; provided that (i) at least 65% of the aggregate principal
amount of Securities issued under the Indenture (calculated after giving effect
to any issuance of Additional Securities) remains outstanding immediately after
the occurrence of such redemption (excluding Securities held by the Company and
its Subsidiaries) and (ii) such

                                      A-6
<PAGE>

redemption shall occur within 90 days of the date of the closing of such Equity
Offering (disregarding the date of the closing of any over-allotment option with
respect thereto).

            SECTION 7. Mandatory Redemption. For the avoidance of doubt, an
offer to purchase pursuant to Section 8 hereof shall not be deemed a redemption.
The Company shall not be required to make mandatory redemption or sinking fund
payments with respect to the Securities.

            SECTION 8. Offers To Purchase. The Indenture provides that upon the
occurrence of a Change of Control or an Asset Sale and subject to further
limitations contained therein, the Company shall make an offer to purchase
outstanding Securities in accordance with the procedures set forth in the
Indenture.

            SECTION 9. Notice of Redemption. Notice of redemption will be mailed
by first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder of Securities to be redeemed at its registered
address. Securities in denominations larger than $1,000 may be redeemed in part.
If any Security is to be redeemed in part only, the notice of redemption that
relates to such Security shall state the portion of the principal amount thereof
to be redeemed. A new Security in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Security. On and after the redemption date interest
ceases to accrue on Securities or portions thereof called for redemption.

            SECTION 10. Denominations, Transfer, Exchange. The Securities are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Securities may be registered and Securities
may be exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company or the Registrar
is not required to transfer or exchange any Security selected for redemption.
Also, the Company or the Registrar is not required to transfer or exchange any
Securities for a period of 15 days before a selection of Securities to be
redeemed.

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

            SECTION 12. Amendment, Supplement and Waiver. Subject to certain
exceptions, the Indenture and the Securities may be amended or supplemented with
the written consent of the Holders of at least a majority in aggregate principal
amount of the Securities then outstanding, and any existing Default or
compliance with any provision may be waived with the consent of the Holders of a
majority in aggregate principal amount of the Securities then outstanding
(except a payment default or in respect of a covenant or provision that cannot
be modified without the consent of each affected Holder). Without notice to or
consent of any Holder, the parties thereto may amend or supplement the Indenture
and the

                                      A-7
<PAGE>

Securities to, among other things, cure any ambiguity, defect or inconsistency
in the Indenture, provide for uncertificated Securities in addition to
certificated Securities, comply with any requirements of the Commission in
connection with the qualification of the Indenture under the TIA, or make any
change that does not adversely affect the legal rights of any Holder of a
Security.

            SECTION 13. Defaults and Remedies. If an Event of Default occurs and
is continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Securities generally may declare all the
Securities to be due and payable immediately. Notwithstanding the foregoing, in
the case of an Event of Default arising from certain events of bankruptcy or
insolvency as set forth in the Indenture, with respect to the Company, all
outstanding Securities will become due and payable without further action or
notice. Holders of the Securities may not enforce the Indenture or the
Securities except as provided in the Indenture. Subject to certain limitations,
Holders of a majority in aggregate principal amount of the then outstanding
Securities may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders notice of any continuing Default (except a
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 Securities then outstanding by notice to the Trustee may
on behalf of the Holders of all of the Securities waive any Default and its
consequences under the Indenture except a continuing Default in the payment of
interest on, or the principal of, the Securities or in respect of certain
covenants set forth in the Indenture.

            SECTION 14. Restrictive Covenants. The Indenture contains certain
covenants that, among other things, limit the ability of the Company and its
Restricted Subsidiaries to make restricted payments, to incur indebtedness, to
create liens, to sell assets, to permit restrictions on dividends and other
payments by Restricted Subsidiaries of the Company, to consolidate, merge or
sell all or substantially all of its assets or to engage in transactions with
affiliates. The limitations are subject to a number of important qualifications
and exceptions. The Company must annually report to the Trustee on compliance
with such limitations.

            SECTION 15. No Recourse Against Others. No director, officer,
employee, incorporator or stockholder of any of the Company, any direct or
indirect parent corporation or any Guarantor, as such, shall have any liability
for any obligations of the Company or the Guarantors under the Securities, the
Indenture, the Guarantors' Guarantees or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder of Securities
by accepting a Security waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the Securities.

            SECTION 16. Trustee Dealings with the Company. The Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with the Company, its Subsidiaries
or their respective Affiliates as if it were not the Trustee.

                                      A-8
<PAGE>

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

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

            SECTION 19. Additional Rights of Holders of Restricted Global
Securities and Restricted Definitive Securities. Pursuant to, but subject to the
exceptions in, the Registration Rights Agreement, the Company and the
Guarantors, if any, will be obligated to consummate an exchange offer pursuant
to which the Holder of this Security shall have the right to exchange this
Initial Security for a 10% Senior Subordinated Note due 2012 of the Company
which shall have been registered under the Securities Act, in like principal
amount and having terms identical in all material respects to this Initial
Security (except that such note shall not be entitled to Additional Interest).
The Holders shall be entitled to receive certain Additional Interest in the
event such exchange offer is not consummated or the Securities are not offered
for resale and upon certain other conditions, all pursuant to and in accordance
with the terms of the Registration Rights Agreement.(1)

            SECTION 20. Guarantees. The Securities will be entitled to the
benefits of certain Guarantees made for the benefit of the Holders. The
Guarantees are subordinated to the payment of Guarantor Senior Debt. Reference
is hereby made to the Indenture for a statement of the respective rights,
limitations of rights, duties and obligations thereunder of the Guarantors, the
Trustee and the Holders.

            SECTION 21. Subordination. The Securities are subordinated to Senior
Debt, as defined in the Indenture. To the extent provided in the Indenture,
Senior Debt must be paid before the Securities may be paid. The Company agrees,
and each Holder by accepting a Security agrees, to the subordination provisions
contained in the Indenture and authorizes the Trustee to give them effect and
appoints the Trustee as attorney-in-fact for such purpose.

            SECTION 22. CUSIP Numbers and ISINs. The Company has caused CUSIP
numbers and ISINs to be printed on the Securities and has directed the Trustee
to use CUSIP numbers and ISINs in notices of redemption as a convenience to the
Holders. No representation is made as to the accuracy of such numbers either as
printed on the Securities or as contained in any notice of redemption and
reliance may be placed only on the other identification numbers placed thereon

"accredited investor" (within the meaning of Rule 501(a) (1), (2), (3) or (7) of

investment in the Securities.

            4. We are acquiring the Securities for our own account (or for
accounts as to which we exercise sole investment discretion and have authority
to make, and do make, the statements contained in this letter) and not with a
view to any distribution of the Securities, subject, nevertheless, to the
understanding that the disposition of our property will at all times be and
remain within our control.

            5. We understand that (a) the Securities will be in registered form
only and that any certificates delivered to us in respect of the Securities will
bear a legend substantially to the following effect:

                  "These Securities have not been registered under the
            Securities Act of 1933. Further offers or sales of these Securities
            are subject to certain restrictions, as set forth in the Offering
            Memorandum dated May 19, 2004 relating to these Securities."

            and (b) the Company has agreed to reissue such certificates without
the foregoing legend only in the event of a disposition of the Securities in
accordance with the provisions of paragraph 6 (provided, in the case of a
disposition of the Securities in accordance with paragraph 6(f) below, that the
legal opinion referred to in such paragraph so permits), or at our request at
such time as we would be permitted to dispose of them in accordance with
paragraph 6(a) below.

            6. We agree that in the event that at some future time we wish to
dispose of any of the Securities, we will not do so unless such disposition is
made in accordance with any applicable securities laws of any state of the
United States and:

            (a) the Securities are sold in compliance with Rule 144(k) under the
Act; or

            (b) the Securities are sold in compliance with Rule 144A under the
Act; or

            (c) the Securities are sold in compliance with Rule 904 of
Regulation S under the Act; or

            (d) the Securities are sold pursuant to an effective registration
statement under the Act; or

            (e) the Securities are sold to the Company or an affiliate (as
defined in Rule 501(b) of Regulation D) of the Company; or

            (f) the Securities are sold to an IAI that is purchasing for its own
account or for the account of such an IAI in each case in a minimum principal
amount of Securities of $250,000 for investment purposes and not with a view to
or for offer or sale in connection with any distribution in violation of the
Securities Act; or

            The Securities are disposed of in any other transaction that does
not require registration under the Act, and we theretofore have furnished to the
Company or its designee an opinion of counsel experienced in securities law
matters to such effect or such other documentation as the Company or its

United States;

            (b) either (i) at the time the buy order was originated, the
transferee was outside the United States or we and any person acting on our
behalf reasonably believed that the transferee was outside the United States or

designated off-shore securities market and neither we nor any person acting on
our behalf knows that the transaction has been pre-arranged with a buyer in the
United States;

            (c) no directed selling efforts have been made in the United States
in contravention of the requirements of Rule 903(a)(2) or Rule 904(a)(2) of
