                                      -2-

consummation of the transaction described in the Stock Purchase Agreement (the

shall implement an equity plan for benefit of the Executive and other members of

                  1.3 EXTENSIONS. The Agreement shall be automatically extended

Corporation or the Executive gives timely notice to the other party that the
term of the Agreement shall not be so extended. Notice under this Section,
whether given by the Corporation or the Executive, shall be given in writing and

                                      -3-

                  The Executive agrees to perform his duties and discharge his
responsibilities in a faithful manner and to the best of his ability. The
Executive agrees to devote his full business time and attention to the
supervision and conduct of the business and affairs of the Corporation and to
faithfully and to the best of his ability promote the interests of the
Corporation. The Executive further agrees that he will engage in no outside
business concerns or activities, and shall not accept other gainful employment,
without the Corporation's written consent. The Corporation hereby acknowledges
and consents to the Executive continuing as a Member of the Board of Directors
of Analogic, Inc. and a Member of the Board of Directors and other membership
related activities of HIMA and HCIA.

                  3.       COMPENSATION AND OTHER BENEFITS.
                           -------------------------------

                  3.1 BASE SALARY. So long as the Executive is employed by the
Corporation pursuant to this Agreement, the Corporation agrees that the
Executive shall receive a base salary earned and payable in bi-weekly
installments. As of the Effective Date of this Agreement, the base salary is
$285,000 per year.

                  The Compensation Committee of the Board of Directors (the
"Compensation Committee"), with the concurrence of the Board of Directors, shall
in good faith review the performance and salary of the Executive on an annual
basis, and shall consider appropriate increases in such salary based on the
successful achievement of agreed upon operating objectives. Such review shall be
made as soon as practicable after the audited financial statements of the
Corporation for the past year are available, and any salary increase authorized
by the Compensation Committee shall be effective at the time specified by the
Committee.

<PAGE>
                                      -4-

                  Notwithstanding the foregoing, for years after 1997, the
Executive's base salary may, at the discretion of the Compensation Committee of
the Board of Directors, be increased annually by an amount that is at least
equal to the cost of living increase as determined by the Compensation
Committee.

                  3.2 ANNUAL BONUS. For each year, including 1997, the Executive
shall be entitled to a bonus targeted at 75% of the base salary paid to the
Executive under this Agreement during the year if the Corporation achieves the
target earnings before income tax, depreciation and amortization ("Target
EBITDA"). The annual Target EBITDA shall be determined for all years, including
1997, by agreement between the Executive and the Compensation Committee. The
Target EBITDA for each year generally shall be as reflected in the annual budget
of the Corporation.

                  For purposes of computing and paying the annual bonus, the
following rules, shall apply:

                       (a) FLOOR EBITDA. In addition to the annual Target
EBITDA, the Executive and the Compensation Committee shall agree upon the
minimum amount of earnings before income tax, depreciation and amortization
("Floor EBITDA") required for the Executive to receive any annual bonus for the
year. The Floor EBITDA for each year generally shall be as reflected in the
annual budget of the Corporation.

                       (b) DETERMINING TARGET AND FLOOR EBITDAS. The Target and
Floor EBITDAs agreed upon by the parties shall be determined after deducting all
profit sharing and compensation payments, including payment of the Executive's
bonus payment due under this Agreement. The Target and Floor EBITDAs for any
year shall be further adjusted for any future recapitalization, stock split,
merger or acquisition, or any other unusual or extraordinary item that would
require adjustment of the EBITDA. For purposes of

<PAGE>
                                      -5-

calculating the annual bonus, (1) all calculations shall be based on the annual
audited financial statements of the Corporation, (ii) all items shall be
classified consistently from year to year and from target amounts to actual
amounts, and (iii) the Compensation Committee shall make appropriate adjustments
for extraordinary items as described above.

                       (c) EBITDA CALCULATIONS. For purposes of the 1997 annual
bonus, the 1997 Target and Floor EBITDAs for the 1997 year, as defined in (h)
below, shall be determined in good faith by agreement of the parties to this
Agreement and such determination shall be made by disregarding all items related
to the Acquisition, including without limitation, change-in-control payments and
any other one-time or other extraordinary compensation amounts payable to the
Executive and others in connection with the Acquisition.

                       (d) BONUS AMOUNT. If the Floor EBITDA for any year is
achieved, the annual bonus will equal 50% of actual base salary paid to the
Executive under this Agreement for such year. If the Target EBITDA for any year
is achieved, the annual bonus will equal 75% of base  salary paid to the
Executive under this Agreement for such year. If the actual EBITDA for the year
in greater than the Floor EBITDA, but less than the Target EBITDA for the year
the annual bonus amount for such year will be extrapolated accordingly. If the
actual EBITDA for the year is less than the Floor EBITDA, the Executive shall
not receive any annual bonus for such year. If the actual EBITDA for the Year is
greater than the Target EBITDA, then the annual bonus amount will be increased
from 75% of base salary by one percent of base salary for each $100,000 by which
the actual EBITDA is greater than the Target EBITDA.

                  Notwithstanding the foregoing, the bonus amount for the 1997
year shall be determined by taking into account only that base salary paid to
the Executive under this Agreement during the 1997 year.

                       (e) COMPUTATION OF BONUS AMOUNT. Computation of the
annual bonus shall be made by the Compensation Committee. The determination of
the Compensation Committee shall be final and conclusive.

                       (f) TIME OF BONUS PAYMENT. The annual bonus shall be paid
to the Executive within 30 calendar days after the receipt of the annual audited
financial statements of the Corporation.

                       (g) FORM OF BONUS PAYMENT. The annual bonus shall be paid
to the Executive in the form of a lump sum payment. The Executive, however,
shall have the option to defer payment of all or a portion of the annual bonus
by entering into a written deferral agreement prior to the date the annual bonus
is payable. Any annual bonus, or portion thereof, that is deferred by the
Executive shall be contributed to, and held in, a rabbi trust established by the
Corporation. The Corporation shall reasonably agree to the terms and conditions
for the deferred payment of the annual bonuses. Such terms and conditions,
including the length of the deferral and the method of paying the deferred
amounts, shall be set forth in a deferral agreement executed by the Executive
and the Corporation. To the extent permitted by law, the assets of the rabbi
trust shall be invested at the discretion of the Executive, and may not be
invested in stock of the Corporation.

                       (h) YEAR. For purposes of this Section, the term "year"
means the calendar year. Notwithstanding the preceding, the "1997 year" shall be
the period beginning on the Effective Date and ending on December 31, 1997.

                  3.3 OTHER BENEFITS. During the term of the Executive's
employment under this Agreement, the Executive shall receive the fringe benefits
provided for the executive officers of the Corporation that may be authorized
from time to time by the Board of

not in addition to) any insurance that may be provided generally to executive
officers. The Corporation will also endeavor to obtain from the life insurance
carrier the option to purchase, at the Executive's sole option and expense,
supplemental life insurance coverage or life insurance covering his dependents
at favorable rates to be determined in advance by the carrier.

                       (b) FINANCIAL PLANNER. Every year, including 1997, the
Corporation shall reimburse the Executive for the reasonable fees and expenses,
not to exceed $5,000, for services rendered by a financial planner selected by
the Executive, in his sole discretion. In addition to any reimbursements
payable to the Executive under this paragraph, the Executive shall receive an
additional payment (a "Gross-Up Payment") in an amount such that after Payment
by the Executive of all taxes imposed on the reimbursement and the Gross-Up
Payment, the Executive retains an amount of the reimbursement and Gross-Up
Payment equal to the reimbursement payable to the Executive under this

                       (c) AUTOMOBILE. The Corporation shall pay the costs of
leasing to the Executive a Ford Expedition equipped with all options and
features selected by the Executive, including the Eddie Bauer options package,

                       (d) VACATION. The Executive shall be entitled to a total
of 160 hours of vacation in each calendar year, at such times as shall be agreed
upon by the Corporation and the Executive and subject to the Corporation's
generally applicable procedures on carryover and accrual. These hours include

                       (e) DISABILITY. The Corporation shall reimburse the
Executive for any premiums paid by the Executive, whether for an individual or
group Policy maintained by the Corporation or for an individual policy selected
and maintained by the Executive or a combination thereof, for disability

                  The Corporation 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

                  5.       DEATH OR PERMANENT DISABILITY OF EXECUTIVE.
                           ------------------------------------------

                  5.1 BENEFITS. If the Executive dies or becomes permanently
disabled during the term of this Agreement, the Corporation shall pay to the
Executive's spouse, if surviving, or legal representatives, in the case of the
Executive's death, or to the Executive, in the case of the Executive's permanent
disability, the following compensation and benefits:

                       (a) SALARY CONTINUATION. The Corporation shall continue
to pay the base salary at the same rate and in the same manner as in effect at
the time the Executive dies or becomes permanently disabled, for the balance of
the term of this Agreement (including any one-year extensions under Section 1.3
that have commenced at the time of such death or disability). If the Executive
dies after becoming permanently disabled and while payments are being made under
this subsection, the remaining payments shall be made to the Executive's spouse,
if surviving, or legal representatives.

                       (b) ANNUAL BONUS. The annual bonus payable pursuant to
Section 3.2 shall be calculated at the end of the year in which the Executive
dies or becomes permanently disabled, as the case may be, and a fraction of such

                                      -10-

disabled. For purposes of this paragraph, the fraction generally shall be
determined using a numerator equal to the number of days that elapse from, and
including, January 1 of the year in which the Executive dies or becomes
permanently disabled until, and including, the date of death or such disability,
as the case may be, and a denominator equal to 365. If the Executive dies or is
permanently disabled during the 1997 year, the numerator shall be equal to the
number of days that elapse from, and including, the Effective Date until, and
including, the date of such death or disability, and the denominator shall be
equal to the number of days in the 1997 year.

options granted to the Executive with respect to which he is not yet vested on

disability, the Corporation shall have the right, but not the obligation, to
purchase (i) any and all shares of capital stock of the Corporation, owned or
previously owned by the Executive or his assignee, and (ii) any and all stock
options granted to the Executive in which he is vested on the date he dies or
becomes permanently disabled, at the Fair Market Value for such shares or
options on the date the Executive dies or becomes permanently disabled.

                  5.2 "PERMANENTLY DISABLED." For purposes of this Agreement,
the Executive shall be "permanently disabled" if he is determined to be
permanently disabled for Purposes of any disability insurance policy maintained
by the Corporation that covers the Executive. If the Corporation maintains no
such policy, the Executive shall be "permanently disabled" if he has a
disability because of which the Executive is physically or mentally unable to
substantially perform his regular duties as President, Chief Executive Officer
or Chairman of the Board of the Corporation for a sufficiently long period of
time such that the

<PAGE>

                                      -11-

business of the Corporation could be materially adversely affected. Any question
as to the existence, extent or potentiality of disability of the Executive upon
which the Executive and the Corporation cannot agree shall be determined by a
qualified independent physician jointly selected by the Executive and the
Corporation (or if the Executive is unable to make such a selection, it shall be
made by an adult member of his immediate family). The determination of such
physician, made in writing to the Corporation and to the Executive, shall be
final and conclusive for all purposes of this Agreement. In the event the
Executive is permanently disabled, the Executive shall cease to be employed on
the last day of the month in which the Executive's disability is determined by
written agreement of the Executive and the Corporation, or the written
determination of a physician, as the case may be.

that if such termination occurs during the initial term of employment ending

to purchase such shares and options from the Executive, the purchase price shall
be paid to the Executive in a single lump sum cash payment. If the Executive
exercises his right to require the Corporation to purchase such shares and
options, payment shall be made in three equal annual installments on the first,
second and third anniversaries of the Executive's termination.

employment and receive the payments and benefits described in paragraph (c)

payable to the Executive for any year commencing after a Reduction Event.

                  If the termination under this Section occurs prior to a
Qualified IPO, the Executive, for a period of twelve months following the date
of termination, shall have the right, but not the obligation, to require the
Corporation to purchase, for cash payable at the time of the sale, (i) all
shares of capital stock of the Corporation owned or previously owned by the
Executive or his assignee, and (ii) any and all stock options granted to the
Executive with respect to all of which he is vested at the time of his
termination (including without limitation those options vested in connection
with the termination), at the Fair Market Value for such shares and options,
provided, that all performance options (but not Super Performance options) shall
be vested upon the Executive's termination under this Section.

                         (b) DEFINITION. For purposes of this Agreement, the
term "Change in Control" shall mean any of the following events:

                            (i) All or substantially all of the assets of the
          Corporation are sold as an entirety to any person or entity or group
          (within the meaning of Rule 13d-5 under the Exchange Act and Sections
          13(d) and 14(d) of the Exchange Act (a "Group")) other than a Group

                            (ii) The stockholders of the Corporation approve a

          merger between or among the affiliates of the Corporation); or

                            (iii) Any person, entity or Group (other than WGL
          Holdings, Inc., its affiliates or their related parties) becomes
          directly or indirectly, the "beneficial owner," as defined in Rule
          13d-3 under the Exchange Act (in a single transaction or in a related

          more than the greater of (1) 40 percent of the total voting power
          entitled to vote in the election of directors of the Corporation (or
          such other persons surviving the transaction) and (2) the total voting
          power entitled to vote in the election of directors of the Corporation
          beneficially owned by WGTL Holdings, Inc., its affiliates or their
          related parties.

                  6.4      TERMINATION FOR CAUSE.
                           ---------------------

                         (a) IN GENERAL. The Corporation may terminate the
Executive's employment in the event that the Executive shall do or cause to be
done any act which constitutes "cause" (as hereinafter defined) for termination.
For purposes of this Agreement, "cause" shall be deemed to mean a material
breach by the Executive of this Agreement, gross negligence or willful
misconduct in the performance of his duties, dishonesty to the Corporation, or
the commission of a felony that results in a conviction in a court of law.

                         (b) OBLIGATIONS. Should the Executive's employment be
terminated by the Corporation for cause, (1) the Corporation shall pay the
Executive his base salary and other compensation under Article 3 of this
Agreement which has accrued as of the date of such termination (excluding any
annual bonus payable pursuant to such Article 3), (2) any and all stock options
granted to the Executive in which he is not yet vested on the date of such
termination shall be forfeited and canceled, and (3) for a period of twelve (12)
months after such termination, the Corporation shall have the right, but not the
obligation, to purchase from the Executive (A) all shares of capital stock owned
or previously owned by the Executive or his assignee (except to the extent such
shares of capital stock were sold in the public market following a Qualified
IPO), and (B) any and all stock options with respect to which the Executive is
vested on the date of such termination, and in such a purchase, the Corporation
shall purchase all such shares and options at a price equal to the lesser of
cost

<PAGE>

                                      -17-

thereof to the Executive or the Fair Market Value for such shares and options
(less the principal amount of any notes due to the Corporation from the
Executive, which notes shall be canceled to the extent that such notes are less
than or equal to such purchase price; any excess shall continue in full force
and effect). The purchase price shall be paid by the Corporation by delivery of
a promissory note, subordinated to all debt of the Corporation, bearing interest
at 7% per annum (which interest may be payable by delivery of notes of like
tenor in principal amount equal to the interest then due) with a maturity one
year beyond the maturity of the Corporation's subordinated debt at Closing of
the Acquisition.

                  6.5 TERMINATION WITHOUT GOOD REASON.
                      -------------------------------

                         (a) IN GENERAL. The Executive shall be entitled to
terminate his employment without good reason at any time. For purposes of this
Section, an election by the Executive under Section 1.3 not to extends this
Agreement beyond the earlier of (i) the date of a Qualified IPO or (ii) June
30, 2002, shall be treated as a termination without good reason under this
Section.

                         (b) OBLIGATIONS. If the Executive's employment
terminates under this Section (1) no additional compensation after the date of
such termination and no annual bonus shall be payable by the Corporation to the
Executive, (2) any and all stock options in which the Executive is not vested on
the date of such termination shall be forfeited and canceled, and (3) if the
termination occurs prior to the earlier of (i) a Qualified IPO, or (ii) June 30,
2002, the Corporation shall, for a period of twelve (12) months after the
termination have the right, but not the obligation, to purchase from the
Executive (i) all shares of capital stock of the Corporation owned or previously
owned by the Executive or his assignee, and (ii) any and all stock options in
which the Executive is vested on the date of such termination, and in such a
purchase the Corporation shall purchase all such shares and options at a price
equal to the lesser of cost thereof to the Executive or the Fair Market

<PAGE>

                                      -18-

Value for such shares and options. The Corporation shall pay the purchase price
in the form of three (3) equal annual installments on the first, second and
third anniversaries of the Executive's termination.

                  6.6      OPTIONS/CORPORATION STOCK.
                           -------------------------

                         (a) FAIR MARKET VALUE. For purposes of this Agreement,
and notwithstanding any provisions to the contrary in any shareholder or stock
option agreement between the Executive and the Corporation, the "Fair Market
Value" of the capital stock of the Corporation, or of any stock options granted
to the Executive, shall mean the value of such stock or options determined by a
certified independent appraiser selected by the Executive and the Corporation.
With respect to any independent appraisal of the Corporation's stock under this
Agreement, in all cases where an independent appraiser is not mutually agreed
upon, each of the parties will select a certified appraiser and those two
appraisers will select a third certified appraiser, whose appraisal shall be
binding on the parties.

                         (b) PURCHASE RIGHTS. For purposes of the capital stock
and stock option purchase rights set forth in Sections 5.1(c), 6.1(c),
6.2(c)(3), 6.3(a)(3), 6.4(b)(3) and 6.5(b)(3):

                            (1) capital stock and stock options shall include
only such stock and stock options acquired by the Executive in connection with
his employment by the Corporation;

                            (2) the right of the Corporation to purchase, and
the right of the Executive to require the Corporation, to purchase capital stock
of the Corporation owned or previously owned by the Executive, shall apply to
shares of capital stock of the Corporation and WGL Holdings, Inc. acquired by
the Executive pursuant to the terms of the equity plan set forth in Exhibit A;

<PAGE>

                                      -19-

                            (3) the right of the Corporation to purchase, and
the right of the Executive to require the Corporation, to purchase any and all
stock options granted to the Executive, shall apply equally to options to
purchase either the capital stock of the Corporation or capital stock of WGL
Holdings, Inc.; and

                            (4) WGL Holdings, Inc. shall have the right to
exercise the purchase rights or obligations, as the case may be, on behalf of
the Corporation.

                         (c) EXERCISE OF OPTIONS. With respect to any
unexercised options that are not cancelled upon termination of the Executive's
employment, including those options vested in connection with the termination,
the Executive shall have the right to exercise all unexercised options for a
period of not less than twelve (12) months commencing on the date of the
Executive's termination.

                         (d) QUALIFIED IPO. For purposes of the Agreement, the
term "Qualified IPO" means a consummated initial public offering of common
shares of the Corporation or WGL Holdings, Inc. which is underwritten on a firm
commitment basis by a nationally-recognized investment banking firm.

                         (e) INCONSISTENT TERMS. To the extent that the terms of
this Agreement are specifically inconsistent with any provisions in any
shareholder or stock option agreement between the Executive and the Corporation
and WGL Holdings, Inc., the terms of this Agreement shall supersede the terms of
any such shareholder or stock option agreement.

                  7. CONFIDENTIALITY.
                     ---------------

                  The Executive shall not, except as required in the performance
of his duties under this Agreement, divulge to any person, at any time during or
after the term of his

                                      -20-

employment with the Corporation, any trade secret of the Corporation, any
privileged or confidential information gained as a result of his employment with
the Corporation, or any document, writing or other tangible item containing or
relating to any such trade secret or privileged or confidential information.

                  8.       NON-COMPETITION.
                           ---------------

                  8.1 During the term of this Agreement and for a period of
twenty-four (24) months after (a) the termination of the Agreement or (b) the
end of the last pay period in respect of which the Executive receives any
compensation or other annual bonus pursuant to the Agreement (except that if the
Executive is terminated by the Corporation without cause, the provisions of
this Article 8 shall be inapplicable), the Executive agrees that he shall not
directly or indirectly, for his own account or as agent, employee, officer,
director, trustee, consultant or shareholder of any person (except for a ten
percent (10%) interest or less in any publicly traded corporation) or a member
of any firm or otherwise, anywhere in the sales territory of the Corporation
engage or attempt to engage in any business activity which is the same as,
substantially similar to or directly competitive with the business of the
Corporation as conducted by it during the term of this Agreement, or
substantially similar to or directly competitive with the related business
activities of the 10 largest customers of the Corporation, ranked by gross
sales, at the time of the termination of the Agreement.

                  8.2 During the term of this Agreement and for a period of one
year from the date of termination of this Agreement for any reason, the
Executive agrees that he shall not, directly or indirectly, for his own account
or as agent, employee, officer, director, trustee, consultant or shareholder of
any person, or member of any firm or otherwise, employ or solicit the employment
of any person employed by the Corporation within twenty-four (24) months prior
to the date of the Executive's termination.

                  9.       RIGHTS TO DISCOVERIES.
                           ---------------------

                  The Executive agrees that all ideas, inventions (whether
patentable or unpatentable), trademarks and other developments or improvements
conceived, developed or acquired by the Executive, whether or not during working
hours, at the premises of the Corporation or elsewhere, alone or with others,
that are within the scope of the Corporation's business operations or that
relate to any work or projects of the Corporation, shall be the sole and
exclusive property of the Corporation. The Executive agrees to disclose promptly
and fully to the Corporation all such ideas, inventions, trademarks or other
developments and, at the request of the Corporation, the Executive shall submit
to the Corporation a full written report thereof regardless of whether the
request for written report is made after the termination of this Agreement. The
Executive agrees that during the term of this Agreement and thereafter, upon the
request of the Corporation and at its expense, he shall execute and deliver any
and all applications, assignments and other instruments which the Corporation
shall deem necessary or advisable to transfer to and vest in the Corporation the
Executive's entire right, title and interest in and to all such ideas,
inventions, trademarks or other developments and to permit and enable the
Corporation to apply for and obtain patents or copyright or trademark
registrations for any such patentable or copyrightable or trademarkable ideas,
inventions, trademarks and other developments, throughout the world. To the
extent applicable law provides that any such idea, invention, trademark or other
development belongs to the Executive rather than the Corporation, the Executive
hereby grants to the Corporation a royalty-free, non-exclusive, worldwide
perpetual license to use such idea, invention, trademark or other development
for no added consideration other than that which is given in connection with
this Agreement.

Executive shall execute any documents relating to the subject of those Articles
as required generally by the Corporation of its executive officers and such

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

                  The Executive acknowledges that the Corporation will
suffer damages incapable of ascertainment in the event that any of the
provisions of Article 7, 8, 9 or 10 hereof are breached and that the Corporation
will be irreparably damaged in the event that the provisions of Articles 7, 8, 9
and 10 are not enforced. Therefore, should any dispute arise with respect to the
breach or threatened breach of Articles 7, 8, 9 or 10 of this Agreement, the
Executive agrees and consents that in addition to any and all other remedies
available to the Corporation, an injunction or restraining order or other
equitable relief may be issued or ordered by a court of competent jurisdiction
restraining any breach or threatened breach of Articles 7, 8, 9 or 10 of this
Agreement. The Executive agrees not to urge in any such action that an adequate
remedy exists at law. The Executive consents to jurisdiction in New York and
venue in Erie County for purposes of all claims arising under this Agreement.

                  13.      TERM OF AGREEMENT.
                           -----------------

                  For the limited purpose of making payments hereunder, and not,
for example, for purposes of extending the periods referenced in Article 8, this
Agreement shall not terminate until all payments hereunder have been made.

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

                  This Agreement shall be governed by the internal domestic laws
of the State of New York without reference to conflict of laws principles. This
Agreement shall be binding upon and inure to the benefit of the legal
representatives, successors and assigns of the parties hereto (provided,

view of its personal nature). All headings and subheadings are for convenience
only and are not of substantive effect. Except as otherwise specifically
provided for herein, this Agreement constitutes the entire agreement between the
parties hereto with respect to the subject matter hereof and supersedes all
prior negotiations, understandings and writings (or any part thereof) whether
oral or written between the parties hereto relating to the subject matter
hereof. Except as specifically referenced herein, no agreements or
representations, oral or otherwise, express or implied, with respect to the
subject matter hereof have been made by either party that are not expressly set
forth in this Agreement. No provision of this Agreement may be waived, modified
or amended, orally or by any course of conduct, unless such waiver, modification
or amendment is set forth in a written agreement duly executed by both of the
parties hereto. If any article, section, portion, subsection or subportion of
this Agreement shall be determined to be unenforceable or invalid, then such
article, section, portion, subsection or subportion shall be modified in the
letter and spirit of this Agreement to the extent permitted by applicable law so
as to be rendered valid and any such determination shall not affect the
remainder of this Agreement, which shall be and remain binding and effective as
against all parties hereto.

Acquisition jointly and severally warrant, covenant and agree as follows:

            (i) as soon as available and in any event within 45 days after the

            (iii) promptly after (a) the sending or filing thereof, copies of
      all reports which Holdings, the Company or any of their Subsidiaries send
      to any lenders pursuant to the Credit Agreement and (b) the sending or
      filing thereof, all reports and registration statements which Holdings,
      the Company or any of their Subsidiaries file with the Securities and
      Exchange Commission or any national securities exchange; and

                                     - 7 -

In the event that, pursuant to the terms of the Notes, an indenture is qualified
under the Trust Indenture Act of 1939 with respect to the Notes, the information
required to be furnished pursuant to this Paragraph 4A shall be limited to
information regarding Holdings and shall be provided pursuant hereto only to
Holders of Shares.

            4B. Information Required by Rule 144A. Holdings will, and will cause
the Company to, upon the request of any Holder, provide such Holder, and any
qualified institutional buyer designated by such Holder, such financial and
other information as such Holder may reasonably determine to be necessary in
order to permit compliance with the information requirements of Rule 144A under
the Securities Act in connection with the resale of Notes or Shares. For the
purpose of this paragraph 48, the term "qualified institutional buyer" shall
have the meaning specified in Rule 144A under the Securities Act. At the request
of holders of in excess of 25% of the aggregate principal amount of the Notes,
Acquisition will use its best efforts to cause the Notes to be eligible for
participation in the book-entry system of The Depository Trust Company.

            4C. Indemnity. Holdings and Acquisition, jointly and severally,
agree and Holdings will cause Intermediate Holdings, jointly and severally with
Holdings and Acquisition, to agree, to indemnify each of the Purchasers, as
debtholders, shareholders, directors and officers of Acquisition and Holdings,
as the case may be, upon demand, from and against any and all liabilities,
obligations, claims, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements (including reasonable fees of attorneys,
accountants, experts and advisors) of any kind or nature whatsoever (in this
section collectively called "liabilities and costs") which to any extent (in
whole or in part) may be imposed on, incurred by, or asserted against any of the
Purchasers arising out of, resulting from or in any other way associated with
the execution, delivery or performance of the Transaction Documents or such
Purchaser's being a debtholder, shareholder, director or officer of Holdings or
Acquisition. The foregoing indemnification shall apply whether or not such
liabilities and costs are in any way or to any extent caused, in whole or in
part, by any negligent act or omission of any kind by such holder, provided only
that no Purchaser shall be entitled under this paragraph to receive
indemnification for that portion, if any, of any liabilities and costs which is
proximately caused by such Purchaser's willful misconduct. If any Person
(including Holdings, Acquisition or any of their respective Affiliates) ever
alleges such willful misconduct by a purchaser, the indemnifi-

<PAGE>
                                     - 8 -

cation provided for in this paragraph shall nonetheless be paid upon demand,
subject to later adjustment or reimbursement, until such time as a court of
competent jurisdiction enters a final judgment as to the extent and effect of
the alleged willful misconduct. As used in this section the term "Purchaser"
shall refer also to each director, officer, agent, attorney, employee,
representative and Affiliate of such Purchaser.

            4D. Additional Interest On the Notes.

            (a) Acquisition and the Purchasers agree that the holders of Notes
will suffer damages if Acquisition fails to fulfill its obligations under
Section 1 of the Note Registration Rights Agreement and that it would not be
feasible to ascertain the extent of such damages with precision. Accordingly,
Acquisition agrees to pay additional interest on the Notes ("Additional
Interest") under the circumstances and to the extent set forth below:

            (i) if a registration statement relating to the Notes has not been
      filed on or prior to the date that is 45 days after the first written
      demand for the filing of such registration statement pursuant to Section
      1(a) (1) of the Note Registration Rights Agreement (the "Required Filing
      Date"), then commencing on the day after the Required Filing Date,
      Additional Interest shall be accrued on the Notes at a rate of .50% per
      annum;

            (ii) if such registration statement is not declared effective on or
      prior to the date that is 45 days after the Required Filing Date, then
      commencing on the day after such date, Additional Interest shall be
      accrued on the Notes at a rate of 50% per annum; and

            (iii) if (A) such registration statement has been declared effective
      and ceases to be effective at any time during the period in which it is
      required to remain effective pursuant to Section 1(c) (2) of the Note
      Registration Rights Agreement or (B) a notice under Section 1(c) (7) with
      respect to such registration statement is effective or required to be
      effective at a time when the aggregate number of days in any 365-day
      period for which all such notices issued or required to be issued pursuant
      to such section have been or were required to be in effect exceeds 30
      days, whether or not consecutive, then Additional Interest shall be
      accrued on the Notes at a rate of .50% per annum immediately following
      the (y) day such registration

<PAGE>
                                     - 9 -

      statement ceases to be effective in the case of (A) above or (z) the date
      on which the 30-day limit is exceeded in the case of (B) above;

provided, however, that (1) upon the filing of such registration statement (in
the case of (i) above), (2) upon the effectiveness of such registration
statement (in the case of (ii) above), or (3) upon the effectiveness of such
registration statement which had ceased to remain effective (in the case of
(iii) (A) above) or, on the date on which a notice issued, or required to be
issued, pursuant to Section 1 (c) (7) is no longer effective or required to be
effective (in the case of (iii) (B) above), Additional Interest on the Notes as
a result of such clause (i), (ii) or (iii) (or the relevant subclause thereof),
as the case may be, shall cease to accrue.

            (b) Acquisition shall notify the Trustee (or, if there is no
Trustee, each Holder) within one business day after each and every date on which
an event occurs in respect of which Additional Interest is required to be paid
(an "Event Date"). Additional Interest shall be paid by depositing with the
Trustee, in trust, for the benefit of the holders of Notes, on or before the
semi-annual interest payment date provided in the Indenture (whether or not any
interest other than Additional Interest is then payable on the Notes),
immediately available funds in sums sufficient to pay the Additional Interest
then due to holders of Notes with respect to which the Trustee serves. The
Additional Interest due shall be payable on each interest payment date to the
record holders of Notes who would be entitled to receive the interest payment to
be made on such date as set forth in the Indenture. Each obligation to pay
Additional Interest shall be deemed to accrue on the applicable Event Date.
Additional Interest on the Notes may not exceed in the aggregate 1.0% per annum.

            The amount of Additional Interest will be determined by multiplying
the applicable Additional Interest rate set forth in clauses (i), (ii) and (iii)
above by the principal amount of the Notes, in each case, multiplied by a
fraction, the numerator of which is the number of days such Additional Interest
rate was applicable during such period (determined on a basis of a 360-day year
comprised of twelve 30-day months) and the denominator of which is 360.

funds) in U.S. Legal Tender or, at the request of a Holder, by wire transfer in
immediately available funds to an account specified in writing by a Holder. The
Company may deliver any such interest payment to the Holder's registered address
or such other address or account as the Holder may designate in writing.

         4. PAYING AGENT AND REGISTRAR. Initially, the Company will act as
Paying Agent (for purposes of receiving surrender or presentment of, but not
deposits of payments on, Notes) and Registrar. The Company may change any such
Paying Agent, Registrar or co-Registrar without notice to the Holders.

         5. INDENTURE. In the event an indenture is required to be qualified
under the Trust Indenture Act of 1939 (U.S. Code ss.ss. 77aaa-77bbbb), as
amended from time to time (the "TIA"), with respect to the Notes, or upon the
request of holders of in excess of 25% in principal amount of outstanding Notes
the Company shall and at any other time the Company, in its sole discretion, may
appoint a Trustee who satisfies the eligibility requirements set forth in
Section 7.10 of the In-

<PAGE>
                                     - 6 -

denture and, in any such event, the Company shall take whatever actions are
necessary to cause an indenture substantially in the form of Exhibit A attached
hereto to be executed and delivered by the Company and the Trustee and to be
qualified under the TIA (which Indenture shall provide for the same restrictions
on transfer set forth hereon if such Indenture is executed and delivered at the
election of the Company). In such event, (i) this Note shall be deemed to be one
of an issue of Notes of the Company issued under the Indenture; (ii) the terms
of the Notes shall be deemed to include those stated in the Indenture and those
made part of the Indenture by reference to the TIA, as amended from time to
time; and (iii) the Notes shall be subject to all such terms. Holders of Notes
are referred to the Indenture and the TIA for a statement of all such term. In
such event, the Company may require holders of the Notes, and each Holder by his
or her acceptance hereof agrees upon the Company's request, to surrender to the
Trustee all Notes in the form hereof in exchange for replacement Notes
substantially in the form of Exhibit A to the Indenture. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the TIA, as in effect on the date of the Indenture. This Note is
one of a duly authorized issue of Notes of the Company consisting of any other
13% Senior Subordinated Notes due 2007 of the Company issued on July 10, 1997
and any replacement Notes issued in exchange for, or in lieu of, the foregoing
in accordance with the Indenture. The Notes are limited in aggregate principal
amount to $___________. Notwithstanding anything to the contrary herein, the
Notes are subject to all such terms, and Holders of Notes are referred to the
Indenture and said Act for a statement of them. The Notes are general unsecured
obligations of the Company.

         6. SUBORDINATION. The Notes are subordinated in right of payment, in
the manner and to the extent set forth in the Indenture, to the prior payment in
full in cash or Cash Equivalents of all Senior Debt of the Company, whether
outstanding on the date of the Indenture or thereafter created, incurred,
assumed or guaranteed. Each Holder by his or her acceptance hereof agrees to be
bound by such provisions and to

<PAGE>
                                     - 7 -

take such action as may be necessary or appropriate to effectuate the
subordination provided for in the Indenture.

         7. REDEMPTION.

         (a) OPTIONAL Redemption. The Notes will be redeemable, at the Company's
option, in whole at any time or in part from time to time, on and after July 1,
1999, at the following redemption prices (expressed as percentages of the
principal amount thereof) if redeemed during the twelve-month period commencing

</TABLE>

         (b) OPTIONAL REDEMPTION UPON PUBLIC EQUITY OFFERINGS. At any time, or
from time to time, on or prior to July 1, 1999, the company may, at its option,
use the net cash proceeds of one or more Public Equity offerings (as defined in
the Indenture) to redeem up to 100% but no less than 50% of the aggregate
principal amount of Notes originally issued at a redemption price equal to 112%
of the principal amount thereof plus, in each case, accrued and unpaid interest
to the date of redemption.

         In order to effect the foregoing redemption with the proceeds of any
Public Equity offering, the Company shall make such redemption not more than 60
days after the consummation of any such Public Equity Offering.

         8. NOTICE OF REDEMPTION. Notice of redemption will be mailed at least
30 days but not more than 60 days before the Redemption Date to each Holder of
Notes to be redeemed at

<PAGE>
                                     - 8 -

such Holder's registered address. Notes in denominations larger than $1,000 may
be redeemed in part.

         Except as set forth in the Indenture, if monies for the redemption of
the Notes called for redemption shall have been deposited with the Paying Agent
for redemption on such Redemption Date, then, unless the Company defaults in the
payment of such Redemption Price plus accrued and unpaid interest, if any, the
Notes called for redemption will cease to bear interest from and after such
Redemption Date and the only right of the Holders of such Notes will be to
receive payment of the Redemption Price plus accrued and unpaid interest, if
any.

         9. OFFERS TO PURCHASE. Sections 4.15 and 4.16 of the Indenture provide
that, after certain Asset Sales (as defined in the Indenture) and upon the
occurrence of a Change of Control (as defined in the Indenture), and subject to
further limitations contained therein, the Company will make an offer to
purchase certain amounts of the Notes in accordance with the procedures set
forth in the Indenture.

         13. DISCHARGE PRIOR TO REDEMPTION OR MATURITY. If the Company at any
time deposits with a trustee who otherwise could qualify to serve as Trustee
under the Indenture U.S. Legal Tender or U.S. Government Obligations sufficient
to pay the principal of and interest on the Notes to redemption or maturity and
complies with the other provisions of the Indenture relating thereto, the
Company will be discharged from certain provisions of the Indenture and the
Notes (including certain covenants, but excluding its obligation to pay the
principal of and interest on the Notes) .

         14. AMENDMENT; SUPPLEMENT; WAIVER. Subject to certain exceptions set
forth in Section 9.02(b) of the Indenture, the Indenture or the Notes may be
amended or supplemented with the written consent of the Holders of at least a
majority in aggregate principal amount of the Notes then outstanding, and any
existing Default or Event of Default or noncompliance with any provision may be
waived with the written consent of the Holders of a majority in aggregate
principal amount of the Notes then outstanding. Without notice to or consent of

supplement the Indenture or the Notes to cure any ambiguity, defect or
inconsistency, provide for uncertificated Notes in addition to or in place of
certificated Notes, or comply with Article Five of the Indenture, comply with
any requirements of the SEC in order to effect or maintain the qualification of
this Indenture under the TIA, make any change that would provide any additional
benefit or rights to the Holders or make any other change that does not
adversely affect in any material respect the rights of any Holder of a Note.

         15. RESTRICTIVE COVENANTS. The Indenture imposes certain limitations on
the ability of the Company and its Restricted Subsidiaries to, among other
things, incur additional Indebtedness, make payments in respect of its Capital
Stock or certain Indebtedness, enter into transactions with Affiliates, create
dividend or other payment restrictions affecting Subsidiaries, merge or
consolidate with any other Person, sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of its assets or adopt a plan of

<PAGE>
                                     - 10 -

of important qualifications and exceptions. The Company must annually report to
the Trustee on compliance with such limitations.

         16. SUCCESSORS. When a successor assumes, in accordance with the
Indenture, all the obligations of its predecessor under the Notes and the
Indenture, the predecessor will be released from those obligations.

         17. DEFAULTS AND REMEDIES. Events of Default shall be as set forth in
the Indenture. If an Event of Default occurs and is continuing, the Holders of
at least 25% in aggregate principal amount of Notes then outstanding may declare
all the Notes to be due and payable in the manner, at the time and with the
effect provided in the Indenture, except that in the case of an Event of Default
arising from certain events of bankruptcy or insolvency, all outstanding Notes
become due and payable immediately without further action or notice. If an Event
of Default occurs and is continuing, Holders of a majority in- principal amount
of the then outstanding Notes may pursue any available remedy at law or in
equity to collect the payment of principal or interest on the Notes or to
enforce the performance of any provision of the Notes. The Company shall pay all
costs of collecting or enforcing payment of the Notes, together with attorneys,
fees and expenses paid or incurred by holders, whether or not suit be brought by
the Holders.

         18. TRUSTEE DEALINGS WITH COMPANY. The Trustee under the Indenture (if
executed and delivered), in its individual or any other capacity, may become the
owner or pledgee of Notes and may otherwise deal with the Company, its
Subsidiaries or their respective Affiliates as if it were not the Trustee.

         19. NO RECOURSE AGAINST OTHERS. No stockholder, director, officer,
employee or incorporator, as such, of the Company shall have any liability for
any obligation of the Company under the Notes or the Indenture or for any claim

Each Holder of a Note by accepting a Note

<PAGE>

consideration for the issuance of the Notes.

      other subdivision.

                                   ARTICLE TWO

                                    THE NOTES

      SECTION 2.01. Form and Dating.

            The Notes and the Trustee's certificate of authentication shall be
substantially in the form of Exhibit A hereto. The Notes may have notations,
legends or endorsements required by law, stock exchange rule or depository rule
or usage. The Company and the Trustee shall approve the form of the Notes and
any notation, legend or endorsement on them. Each Note shall be dated the date
of its issuance and shall show the date of its authentication.

            The terms and provisions contained in the Notes, annexed hereto as
Exhibit A, shall constitute, and are hereby expressly made, a part of this
Indenture and, to the extent applicable, the Company and the Trustee, by their
execution and delivery of this Indenture, expressly agree to such terms and
provisions and to be bound thereby.

      SECTION 2.02. Execution and Authentication; Aggregate Principal Amount.

            Two Officers, or an Officer and an Assistant Secretary, shall sign,
or one Officer shall sign and one Officer or an Assistant Secretary (each of
whom shall, in each case, have been duly authorized by all requisite corporate
actions) shall attest to, the Notes for the Company by manual or facsimile
signature. The Company's seal shall also be reproduced on the Notes.

            If an Officer or Assistant Secretary whose signature is on a Note
was an Officer or Assistant Secretary at the time of such execution but no
longer holds that office or position at the time the Trustee authenticates the
Note, the Note shall nevertheless be valid.

            A Note shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authenti-

<PAGE>
                                     - 30 -

cation on the Note. The signature shall be conclusive evidence that the Note has
been authenticated under this Indenture.

            The Trustee shall authenticate Notes for original issue in the
aggregate principal amount not to exceed $25,000,000, upon written orders of the
Company in the form of an Officers' Certificate. The Officers' Certificate shall
specify the amount of Notes to be authenticated, the date on which the Notes are
to be authenticated and the aggregate principal amount of Notes outstanding on
the date of authentication. The aggregate principal amount of Notes outstanding
at any time may not exceed $25,000,000, except as provided in Section 2.07.

            The Trustee shall not be required to authenticate Notes if the
issuance of such Notes pursuant to this Indenture will affect the Trustee's own
rights, duties or immunities under the Notes and this Indenture in a manner
which is not reasonably acceptable to the Trustee.

            The Trustee may appoint an authenticating agent (the "Authenticating
Agent") reasonably acceptable to the Company to authenticate Notes. Unless
otherwise provided in the appointment, an Authenticating Agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such Authenticating
Agent. An Authenticating Agent has the same rights as an Agent to deal with the
Company and Affiliates of the Company.

            The Notes shall be issuable in fully registered form only, without
coupons, in denominations of $1,000 and any integral multiple thereof.

      SECTION 2.03. Registrar and Paying Agent.

            The Company shall maintain an office or agency (which shall be
located in the Borough of Manhattan in the City of New York, State of New York)
where (a) Notes may be presented or surrendered for registration of transfer or
for exchange ("Registrar"), (b) Notes may be presented or surrendered for
payment ("Paying Agent") and (c) notices and demands to or upon the Company in
respect of the Notes and this Indenture may be served. The Registrar shall keep
a register of the Notes and of their transfer and exchange. The Company, upon
prior written notice to the Trustee, may have one or more co-Registrars and one
or more additional paying agents reasonably acceptable to the Trustee. The term
"Paying Agent" includes any addi-

<PAGE>
                                     - 31 -

tional Paying Agent. Neither the Company nor any Affiliate of the Company may
act as Paying Agent.

            The Company shall enter into an appropriate agency agreement with
any Agent not a party to this Indenture, which agreement shall incorporate the
provisions of the TIA and implement the provisions of this Indenture that relate
to such Agent. The Company shall notify the Trustee, in advance, of the name and
address of any such Agent. If the Company fails to maintain a Registrar or
Paying Agent, or fails to give the foregoing notice, the Trustee shall act as
such.

            The Company initially appoints the Trustee as Registrar, Paying
Agent and agent for service of demands and notices in connection with the Notes,
until such time as the Trustee has resigned or a successor has been appointed.
The Paying Agent or Registrar may resign upon 30 days notice to the Company.

      SECTION 2.04. Paying Agent To Hold Assets in Trust.

            The Company shall require each Paying Agent other than the Trustee
to agree in writing that each Paying Agent shall hold in trust for the benefit
of the Holders or the Trustee all assets held by the Paying Agent for the
payment of principal of, or interest on, the Notes (whether such assets have
been distributed to it by the Company or any other obligor on the Notes), and
the Company and the Paying Agent shall notify the Trustee of any Default by the
Company (or any other obligor on the Notes) in making any such payment. The
Company at any time may require a Paying Agent to distribute all assets held by
it to the Trustee and account for any assets disbursed and the Trustee may at
any time during the continuance of any payment Default, upon written request to
a Paying Agent, require such Paying Agent to distribute all assets held by it to
the Trustee and to account for any assets distributed. Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent, the Paying Agent shall have no further liability for such assets.

      SECTION 2.05. Noteholder 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
the Holders. If the Trustee is not the Registrar, the Company shall furnish or
cause the Registrar to furnish to the Trustee before each Record Date and at
such other times as the Trustee may request in writing a list as of

<PAGE>
                                     - 32 -

such date and in such form as the Trustee may reasonably require of the names
and addresses of the Holders, which list may be conclusively relied upon by the
Trustee.

      SECTION 2.06. Transfer and Exchange.

            When Notes are presented to the Registrar or a co-Registrar with a
request to register the transfer of such Notes or to exchange such Notes for an
equal principal amount of Notes of other authorized denominations, the Registrar
or co-Registrar shall register the transfer or make the exchange as requested if
its requirements for such transaction are met; provided, however, that the Notes
presented or surrendered for registration of transfer or exchange shall be duly
endorsed or accompanied by a written instrument of transfer in form satisfactory
to the Company and the Registrar or co-Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing. To permit registrations of
transfer and exchanges, the Company shall execute and the Trustee shall
authenticate Notes at the Registrar's or co-Registrar's request. No service
charge shall be made for any registration of transfer or exchange, but the
Company may require payment of a sum sufficient to cover any transfer tax or
similar governmental charge payable in connection therewith (other than any such
transfer taxes or similar governmental charge payable upon exchanges or
transfers pursuant to Sections 2.10, 3.06, 4.15, 4.16 or 9.06, in which event
the Company shall be responsible for the payment of such taxes).

            The Registrar or co-Registrar shall not be required to register the
transfer of or exchange of any Note (i) during a period beginning at the opening
of business 15 days before the mailing of a notice of redemption of Notes and
ending at the close of business on the day of such mailing and (ii) selected for
redemption in whole or in part pursuant to Article Three, except the unredeemed
portion of any Note being redeemed in part.

      SECTION 2.07. Replacement Notes.

            If a mutilated Note is surrendered to the Trustee or if the Holder
of a Note claims that the Note has been lost, destroyed or wrongfully taken, the
Company shall issue and the Trustee shall authenticate a replacement Note if the
Trustee's requirements are met. If required by the Trustee or the Company, such
Holder must provide an affidavit of lost certificate and an indemnity bond or
other indemnity, sufficient in the judgment of both the Company and the Trustee,
to protect the

<PAGE>
                                     - 33 -

Company, the Trustee or any Agent from any loss which any of them may suffer if
a Note is replaced. The Company may charge such Holder for its reasonable,
out-of-pocket expenses in replacing a Note, including reasonable fees and
expenses of counsel. Every replacement Note shall constitute an additional
obligation of the Company, and shall be entitled to the benefits of this
Indenture.

      SECTION 2.08. Outstanding Notes.

            Notes outstanding at any time are all the Notes that have been
authenticated by the Trustee except those cancelled by it, those delivered to it
for cancellation and those described in this Section as not outstanding. Subject
to the provisions of Section 2.09, a Note does not cease to be outstanding
because the Company or any of its Affiliates holds the Note.

            If a Note is replaced pursuant to Section 2.07 (other than a
mutilated Note surrendered for replacement), it ceases to be outstanding unless
the Trustee receives an Opinion of Counsel that the replaced Note is held by a
bona fide purchaser. A mutilated Note ceases to be outstanding upon surrender of
such Note and replacement thereof pursuant to Section 2.07.

            If on a Redemption Date or the Maturity Date the Paying Agent holds
U.S. Legal Tender or U.S. Government Obligations sufficient to pay all of the
principal and interest due on the Notes payable on that date and is not
prohibited from paying such money to the Holders thereof pursuant to the terms
of this Indenture, then on and after that date such Notes cease to be
outstanding and interest on them ceases to accrue.

      SECTION 2.09. Treasury Motes.

            In determining whether the Holders of the required principal amount
of Notes have concurred in any direction, waiver, consent or notice, Notes owned
by the Company or any of its Affiliates shall be considered as though they are
not outstanding, except that for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Notes which a Trust Officer of the Trustee actually knows are so owned shall be
so considered. The Company shall notify the Trustee, in writing, when it or any
of its Affiliates repurchases or otherwise acquires Notes, of the aggregate
principal amount of such Notes so repurchased or otherwise acquired.

<PAGE>
                                     - 34 -

      SECTION 2.10. Temporary Notes.

            Until definitive Notes are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary Notes upon receipt of a
written order of the Company in the form of an Officers' Certificate. The
Officers' Certificate shall specify the amount of temporary Notes to be
authenticated and the date on which the temporary Notes are to be authenticated.
Temporary Notes shall be substantially in the form of definitive Notes but may
have variations that the Company considers appropriate for temporary Notes.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate upon receipt of a written order of the Company pursuant to Section
2.02 definitive Notes in exchange for temporary Notes.

      SECTION 2.2.1. Cancellation.

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

      SECTION 2.12. Payment of Interest; Defaulted Interest.

            Interest on any Note which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Note is registered in the register maintained by the Registrar
at the close of business on the Record Date for such interest.

            If the Company defaults in a payment of interest on the Notes, such
interest shall forthwith cease to be payable to the Holder on the relevant
Record Date by virtue of having been such Holder, and the Company shall pay the
defaulted interest, plus (to the extent lawful) any interest payable on the de-

<PAGE>
                                     - 35 -

faulted interest to the Persons who are Holders on a subsequent special record
date, which date shall be the fifteenth day next preceding the date fixed by the
Company 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 the subsequent
special record date, the Company shall mail to each Holder, as of a recent date
selected by the Company, 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.

      SECTION 2.13. CUSIP Number.

            The Company in issuing the Notes may use a "CUSIP" number, and if
so, the Trustee shall use the CUSIP number in notices of redemption or exchange
as a convenience to Holders; provided that no representation is hereby deemed to
be made by the Trustee as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Notes, and that reliance may be placed only on
the other identification numbers printed on the Notes. The Company shall
promptly notify the Trustee of any change in the CUSIP number.

      SECTION 2.14. Deposit of Moneys.

            Prior to 11:00 a.m. New York City time on each Interest Payment Date
and on the Maturity Date, the Company shall have deposited with the Paying Agent
in immediately available funds money sufficient to make cash payments, if any,
due on such Interest Payment Date or Maturity 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 or Maturity Date, as the case may be.

      SECTION 22.5. Persons Deemed Owners.

            Prior to due presentment of a Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Note is registered in the register maintained by the
Registrar as the owner of such Note for the purpose of receiving payment of
principal of and (subject to Section 2.12) interest on such Note and for all
other purposes whatsoever, whether or not such Note be overdue, and neither the
Company, the Trustee nor any agent of the Company or the Trustee shall be
affected by notice to the contrary.

                                  ARTICLE THREE

                                   REDEMPTION

      SECTION 3.01. Notices to Trustee.

            If the Company elects to redeem Notes pursuant to Paragraph 7 of the
Notes, it shall notify the Trustee and the Paying Agent in writing of the
Redemption Date and the principal amount of the Notes to be redeemed.

            The Company shall give each notice provided for in this Section 3.01
at least 60 days before the Redemption Date (unless a shorter notice period
shall be satisfactory to the Trustee, as evidenced in a writing signed on behalf
of the Trustee), together with an Officers' Certificate stating that such
redemption shall comply with the conditions contained herein and in the Notes.

      SECTION 3.02. Selection of Notes To Be Redeemed.

            If fewer than all of the Notes are to be redeemed, selection of the
Notes to be redeemed will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed or, if the Notes are not then listed on a national securities
exchange, on a pro rata basis, by lot or in such other fair and reasonable
manner chosen at the discretion of the Trustee; provided, however, that if a
partial redemption is made with the proceeds of a Public Equity Offering,
selection of the Notes or portion thereof for redemption shall be made by the
Trustee only on a pro rata basis, unless such method is otherwise prohibited.
The Company shall promptly notify the Trustee and the Paying Agent in writing of
the date of listing and the name of the securities exchange if and when the
Notes are listed on a principal national securities exchange. The Trustee shall
make the selection from the Notes outstanding and not previously called for
redemption and shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes in denominations
of $l,000 may be redeemed only in whole. The Trustee may select for redemption
portions (equal to $1,000 or any integral multiple thereof) of the principal of
Notes that have denominations larger than $1,000. Provisions of this Indenture
that apply to Notes called for redemption also apply to portions of Notes called
for redemption.

                                     - 37 -

      SECTION 3.03. Notice of Redemption.

            At least 30 days but not more than 60 days before a Redemption Date,
the Company shall mail or cause to be mailed a notice of redemption by first
class mail, postage prepaid, to each Holder whose Notes are to be redeemed, with
a copy to the Trustee and any Paying Agent. At the Company's written request,
the Trustee shall give the notice of redemption in the Company's name and at the
Company's expense.

            Each notice for redemption shall identify the Notes 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) the subparagraph of the Notes pursuant to which such redemption
      is being made;

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

            (6) that, unless the Company defaults in making the redemption
      payment, interest on Notes called for redemption ceases to accrue on and
      after the Redemption Date, and the only remaining right of the Holders of
      such Notes is to receive payment of the Redemption Price plus accrued
      interest, if any, to the Redemption Date, upon surrender to the Paying
      Agent of the Notes redeemed;

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

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

                                     - 38 -

      SECTION 3.04. Effect of Notice of Redemption.

            Once notice of redemption is mailed in accordance with Section 3.03,
Notes 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 Notes 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 referred to in Section 2.12.

      SECTION 3.05. Deposit of Redemption Price.

            On or before 11:00 a.m. New York City time on the Redemption Date,
the Company shall deposit with the Paying Agent U.S. Legal Tender sufficient to
pay the Redemption Price plus accrued interest, if any, of all Notes to be
redeemed on that date. The Paying Agent shall promptly return to the Company any
U.S. Legal Tender so deposited which is not required for that purpose, except
with respect to monies owed as obligations to the Trustee pursuant to Article
Seven.

            If the Company complies with the preceding paragraph, then, unless
the Company defaults in the payment of such Redemption Price plus accrued
interest, if any, interest on the Notes to be redeemed will cease to accrue on
and after the applicable Redemption Date, whether or not such Notes are
presented for payment.

      SECTION 3.06. Notes Redeemed in Part.

            Upon surrender of a Note that is to be redeemed in part, the Company
shall execute and the Trustee shall authenticate for the Holder a new Note or
Notes equal in principal amount to the unredeemed portion of the Note
surrendered.

                                  ARTICLE FOUR

                                    COVENANTS

      SECTION 4.01. Payment of Notes.

            The Company shall pay the principal of and interest on the Notes on
the dates and in the manner provided in the

<PAGE>
                                     - 39 -

Notes and in this Indenture. An installment of principal of or interest on the
Notes shall be considered paid on the date it is due if the Trustee or Paying
Agent (other than the Company or an Affiliate of the Company) holds on that date
U.S. Legal Tender designated for and sufficient to pay the installment in full
and is not prohibited from paying such money to the Holders pursuant to the
terms of this Indenture.

            The Company shall pay, to the extent such payments are lawful,
interest on overdue principal and on overdue installments of interest (without
regard to any applicable grace periods) from time to time on demand at the rate
borne by the Notes plus 2% per annum. Interest will be computed on the basis of
a 360-day year comprised of twelve 30-day months.

      SECTION 4.02. Maintenance of Office or Agency.

            The Company shall maintain the office or agency required under
Section 2.03. The Company shall give prior written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company 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 11.02.

      SECTION 4.03. Corporate Existence.

            Except as otherwise permitted by Article Five and Section 4.16, the
Company shall do or cause to be done, at its own cost and expense, all things
necessary to preserve and keep in full force and effect its corporate existence
and the corporate existence of each of its Restricted Subsidiaries in accordance
with the respective organizational documents of each such Restricted Subsidiary
and the material rights (charter and statutory) and franchises of the Company
and each such Restricted Subsidiary; provided, however, that the Company shall
not be required to preserve any such right or franchise, or the corporate,
partnership or other existence of the Company or any Restricted Subsidiary of
the Company, if the Board of Directors of the Company shall determine in good
faith (which such determination shall be evidenced by a Board Resolution) that
the preservation thereof is no longer desirable in the conduct of the business
of the Company and its respective Restricted Subsidiaries taken as a whole and
the loss thereof is not adverse in any material respect to the Holders; and
provided further that any Restricted Subsidiary of the Company may consolidate

<PAGE>
                                     - 40 -

with, merge into, or transfer or distribute all or part of its properties and
assets to, the Company or any Wholly Owned Restricted Subsidiary of the Company.

      SECTION 4.04. Payment of Taxes and Other Claims.

            The Company shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (i) all taxes, assessments
and governmental charges (including withholding taxes and any penalties,
interest and additions to taxes) levied or imposed upon it or any of its
Subsidiaries or properties of it or any of its Subsidiaries and (ii) all lawful
claims for labor, materials and supplies that, if unpaid, might by law become a
Lien upon the property of it or any of its Subsidiaries; provided, however, that
the Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim (y) whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings properly instituted and diligently conducted for which adequate
reserves have been taken or (z) the failure to pay or discharge, or cause to be
paid or discharged such tax, assessment, charge or claim would not reasonably be
expected to result in a material adverse effect on the business operations or
financial condition of the Company.

      SECTION 4.05. Maintenance of Properties and Insurance.

            (a) The Company shall, and shall cause each of its Restricted
Subsidiaries to, maintain its material properties in good working order and
condition (subject to ordinary wear and tear) and make all necessary repairs,
renewals, replacements, additions, betterments and improvements thereto and
actively conduct and carry on its business; provided, however, that nothing in
this Section 4.05 shall prevent the Company or any of its Restricted
Subsidiaries from discontinuing the operation and maintenance of any of its
properties, if such discontinuance is, in the good faith judgment of the Board
of Directors of the Company or the Restricted Subsidiary, as the case may be,
desirable in the conduct of their respective businesses and is not
disadvantageous in any material respect to the Holders.

            (b) The Company shall provide or cause to be provided, for itself
and each of its Restricted Subsidiaries, insurance against loss or damage of the
kinds that, in the good faith judgment of the Board of Directors of the Company,
are adequate and appropriate for the conduct of the business of the Company and
such Restricted Subsidiaries in a prudent manner,

<PAGE>
                                     - 41 -

with reputable insurers or with the government of the United States of America
or an agency or instrumentality thereof, in such amounts, with such deductibles,
and by such methods as shall be customary, in the good faith judgment of the
Board of Directors of the Company, for companies similarly situated in the
industry.

      SECTION 4.06. Compliance Certificate; Notice of Default.

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

            (b) The annual financial statements delivered pursuant to Section
4.08 shall be accompanied by a written report of the Company's independent
accountants (who shall be a firm of established national reputation) that in
conducting their audit of such financial statements nothing has come to their
attention that would lead them to believe that the Company has violated any
provisions of Article Four, Five or Six of this Indenture insofar as they relate
to accounting matters or, if any such violation has occurred, specifying the
nature and period of existence thereof, it being understood that such
accountants shall not be liable directly or indirectly to any Person for any
failure to obtain knowledge of any such violation.

            (c) (i) If any Default or Event of Default has occurred and is
continuing or (ii) if any Holder seeks to exercise any remedy hereunder with
respect to a claimed Default under this Indenture or the Notes, the Company
shall deliver to the Trustee, at its address set forth in Section 11.02 hereof,

<PAGE>
                                     - 42 -

by registered or certified mail or by telegram, telex or facsimile transmission
followed by hard copy by registered or certified mail an Officers' Certificate
specifying such event, notice or other action within five Business Days of its
becoming aware of such occurrence.

      SECTION 4.07. Compliance with Laws.

            The Company shall comply, and shall cause each of its Subsidiaries
to comply, with all applicable statutes, rules, regulations, orders and
restrictions of the United States of America, 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 for such noncompliances as are not in the aggregate
reasonably likely to have a material adverse effect on the financial condition
or results of operations of the Company and its Restricted Subsidiaries, taken
as a whole.

      SECTION 4.08. SEC Reports.

            (a) So long as the Notes are outstanding, if the Company is required
to file annual or quarterly reports with the SEC under Section 13 or 15(d) of
the Exchange Act, the Company (at its own expense) shall file with the SEC and
shall file with the Trustee within 15 days after it files them with the SEC
copies of the quarterly and annual reports and of the information, documents,
and other reports (or copies of such portions of any of the foregoing as the SEC
may by rules and regulations prescribe) required to be filed pursuant to Section
13 or 15(d) of the Exchange Act. Upon qualification of this Indenture under the
TIA, the Company shall also comply with the provisions of TIA ss. 314(a).

            (b) At the Company's expense, the Company shall cause an annual
report, if furnished by it to its stockholders generally and each quarterly or
other financial report if furnished by it to its stockholders generally to be
filed with the Trustee and mailed to the Holders at their addresses appearing in
the register of Notes maintained by the Registrar at the time of such mailing or
furnishing to stockholders.

            (c) If the Company is not required to file annual or quarterly
reports with the SEC under Section 13 or 15(d) of the Exchange Act for any
fiscal period ending after the Issue Date, the Company shall cause its
consolidated financial statements,

<PAGE>
                                     - 43 -

including any notes thereto (and, in the case of a fiscal year end, an auditor's
report by an accounting firm of nationally established reputation), and a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" comparable to that which would have been required to appear in
annual or quarterly reports filed under Section 13 or 15(d) of the Exchange Act
if the Company had a class of securities listed on a national securities
exchange, to be so filed with the Trustee and mailed to the Holders at their
addresses appearing in the register of Notes maintained by the Registrar within
100 days after the end of each fiscal year and within 50 days after the end of
each of the Company's first three fiscal quarters in each fiscal year.

            (d) The Company shall provide to any Holder any information
reasonably requested by such Holder concerning the Company (including financial
statements) necessary in order to permit such Holder to sell or transfer Notes
in compliance with Rule 144A under the Securities Act.

      SECTION 4.09. Waiver of Stay, Extension or Usury Laws.

            The Company covenants (to the extent that it may lawfully do so)
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 Company from paying
all or any portion of the principal of or interest on the Notes 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
that it may lawfully do so) the Company hereby expressly waives all benefit or
advantage of any such law, and covenants 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 4.10. Limitation on Restricted Payments.

            The Company shall not, and shall not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, (a) declare or pay any
dividend or make any distribution (other than dividends or distributions payable
in Qualified Capital Stock or Qualified Rights of the Company) on or in respect
of shares of the Company's Capital Stock to holders of such Capital Stock, (b)
purchase, redeem or otherwise acquire or retire for value any Capital Stock of
the Company or any warrants,

<PAGE>
                                     - 44 -

rights or options to purchase or acquire shares of any class of such Capital
Stock, (c) make any principal payment on, purchase, defease, redeem, prepay,
decrease or otherwise acquire or retire for value, prior to any scheduled final
maturity, scheduled repayment or scheduled sinking fund payment, any
Indebtedness of the Company that is subordinate or junior in right of payment to
the Notes or (d) make any Investment (other than Permitted Investments) (each of
the foregoing actions set forth in clauses (a), (b) (c) and (d) being referred
to as a "Restricted Payment"), if at the time of such Restricted Payment or
immediately after giving effect thereto, (i) a Default or an Event of Default
shall have occurred and be continuing or (ii) the Company is not able to incur
at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) in
compliance with Section 4.12 or (iii) the aggregate amount of Restricted
Payments (including such proposed Restricted Payment) made subsequent to the
Issue Date (the amount expended for such purposes, if other than in cash, being
the fair market value of such property) shall exceed the sum of: (w) 50% of the
cumulative Consolidated Net Income (or if cumulative Consolidated Net Income
shall be a loss, minus 100% of such loss) of the Company earned subsequent to
the Issue Date and on or prior to the date the Restricted Payment occurs (the
"Reference Date") (treating such period as a single accounting period); plus (x)
100% of (i) the aggregate net cash proceeds received by the Company from any
Person (other than a Subsidiary of the Company) from the issuance and sale
subsequent to the Issue Date and on or prior to the Reference Date of Qualified
Capital Stock of the Company and (ii) the aggregate net proceeds (as defined
below) received by the Company from any Person (other than a Subsidiary of the
Company) from the issuance subsequent to the Issue Date and on or prior to the
Reference Date of Qualified Capital Stock of the Company upon conversion or
exchange of Indebtedness of the Company (other than such Indebtedness that is
subordinate or junior in right of payment to the Notes); plus (y) without
duplication of any amounts included in clause (iii) (x) above, 100% of the
aggregate net cash proceeds of any equity contribution received by the Company
from a holder of the Company's Capital Stock; plus (z) without duplication and
to the extent amounts would not be included in Consolidated Net Income, the sum
of (1) the aggregate amount returned in cash on or with respect to Investments
(other than Permitted Investments) made subsequent to the Issue Date, (2) the
net cash proceeds received by the Company or any Restricted Subsidiary from the
disposition of all or any portion of such Investments (other than to the Company
or a Restricted Subsidiary of the Company) and (3) upon redesignation of an
Unrestricted Subsidiary as a Restricted Subsidiary, the fair market value of
such

<PAGE>
                                     - 45 -

Subsidiary; provided, however, that with respect to all Investments made in any
Unrestricted Subsidiary or joint venture, the sum of clauses (1), (2) and (3)
above with respect to such Investment shall not exceed the aggregate amount of
all such Investments made subsequent to the Issue Date in such Unrestricted
Subsidiary or joint venture.

            For the purposes of this Section 4.10, the net proceeds from the
issuance of shares of Qualified Capital Stock of the Company upon conversion or
exchange of Indebtedness shall be deemed to be an amount equal to the net book
value of such Indebtedness (plus the additional amount required to be paid upon
such conversion, if any), less any cash payment on account of fractional shares;
the "net book value" of Indebtedness shall be the amount received by the
Company on the incurrence of such Indebtedness, as adjusted on the books of the
Company to the date of conversion or exchange.

            Notwithstanding the foregoing, the provisions of (ii) and (iii) set
forth in the first paragraph of this Section do not prohibit: (l) the payment of
any dividend within 60 days after the date of declaration of such dividend if
the dividend would have been permitted on the date of declaration; (2) the
acquisition or retirement for value of any shares of Capital Stock of the
Company or warrants, rights or options to purchase or acquire shares of any
class of such Capital Stock, either (i) solely in exchange for shares of
Qualified Capital Stock or Qualified Rights of the Company or (ii) through the
application of net proceeds of a substantially concurrent sale for cash (other
than to a Subsidiary of the Company) of shares of Qualified Capital Stock or
Qualified Rights of the Company; (3) the acquisition or retirement for value of
any Indebtedness of the Company that is subordinate or junior in right of
payment to the Notes solely in exchange for shares of Qualified Capital Stock or
Qualified Rights of the Company; (4) Permitted Holdings Payments; or (5) any
Restricted Payment designated by written notice to the Trustee as being made
pursuant to this clause (5) which, when added together with all other Restricted
Payments previously so designated, does not exceed $1,000,000. In determining
the aggregate amount of Restricted Payments made subsequent to the Issue Date in
accordance with clause (iii) of the first paragraph of this Section, (y) amounts
expended pursuant to clauses (1), (2) (ii), (4) (to the extent such payments are
made pursuant to clause (B) or (C) of the definition of Permitted Holdings
Payment", but with respect to such clause (B), solely to the extent of any
Permitted Holdings Payment made to permit Holdings to pay an expense specified
therein that is an expense of Holdings and its Subsidiaries, but is not

<PAGE>
                                     - 46 -

an expense of the Company and its Restricted Subsidiaries, as determined on a
consolidated basis in accordance with GAAP) and (5) as well as amounts expended
pursuant to clause (ix) of the definition of "Permitted Investments" shall be
included in such calculation and (z) amounts expended pursuant to clauses
(2)(i), (3) and (4) (except as aforesaid) shall be excluded from such
calculation.

            Not later than the date of making any Restricted Payment, the
Company shall deliver to the Trustee an Officers' Certificate stating that such
Restricted Payment complies with this Indenture and setting forth in reasonable
detail the basis upon which the required calculations were computed, which
calculations may be based upon the Company's latest available internal quarterly
financial statements.

      SECTION 4.11. Limitation on Transactions with Affiliates.

            (a) The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, enter into or permit to
exist any transaction or series of related transactions (including, without
limitation, the purchase, sale, lease or exchange of any property or the
rendering of any service) with, or for the benefit of, any of its Affiliates
(each an "Affiliate Transaction"), other than (x) Affiliate Transactions
permitted under paragraph (b) below and (y) Affiliate Transactions conducted in
good faith, the terms of which are fair and reasonable to the Company or such
Restricted Subsidiary and which are no less favorable to the Company or such
Restricted Subsidiary than those that might reasonably have been obtained in a
comparable transaction at such time on an arm's-length basis from a Person that
is not an Affiliate of the Company or such Restricted Subsidiary. All Affiliate
Transactions (and each series of related Affiliate Transactions which are
similar or part of a common plan) involving aggregate payments or other property
with a fair market value in excess of $500,000 shall be approved by the Board of
Directors of the Company or such Restricted Subsidiary, as the case may be, such
approval to be evidenced by a Board Resolution stating that such Board of
Directors has determined that such transaction complies with the foregoing
provisions. If the Company or any Restricted Subsidiary of the Company enters
into an Affiliate Transaction (or a series of related Affiliate Transactions
related to a common plan) that involves an aggregate fair market value or
payments to an Affiliate, as the case may be, of more than $2,500,000, the
Company or such Restricted Subsidiary, as the case may be, shall, prior to the
consumma-

<PAGE>
                                     - 47 -

tion thereof, obtain a favorable opinion as to the fairness of such transaction
or series of related transactions to the Company or the relevant Restricted
Subsidiary, as the case may be, from a financial point of view, from an
Independent Financial Advisor and file the same with the Trustee.

            (b) The foregoing restrictions shall not apply to (i) reasonable
fees, compensation and out-of-pocket expenses paid to and indemnity provided on
behalf of, officers, directors, employees or consultants of the Company or any
Restricted Subsidiary of the Company as determined in good faith by the
Company's Board of Directors or senior management; (ii) transactions between or
among the Company and any of its Restricted Subsidiaries or exclusively between
or among such Restricted Subsidiaries, provided that such transactions are not
otherwise prohibited by this Indenture; (iii) the agreement between the Company
and Donaldson, Lufkin & Jenrette Securities Corporation as in effect as of the
Issue Date or any amendment thereto or any transaction contemplated thereby
(including pursuant to any amendment thereto) in any replacement agreement
thereto so long as any such amendment or replacement agreement is not more
disadvantageous to the Holders in any material respect than the original
agreement as in effect on the Issue Date; (iv) Restricted Payments and Permitted
Investments permitted by this Indenture; and (v) any Permitted Holdings Payment.

      SECTION 4.12. Limitation on Incurrence of Additional Indebtedness.

            The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, assume, guarantee,
acquire, become liable, contingently or otherwise, with respect to, or otherwise
become responsible for payment of (collectively, "incur") any Indebtedness
(other than Permitted Indebtedness); provided, however, that if no Default or
Event of Default shall have occurred and be continuing at the time or as a
consequence of the incurrence of any such Indebtedness, the Company may incur
Indebtedness (including, without limitation, Acquired Indebtedness) and the
Restricted Subsidiaries of the Company may incur Acquired Indebtedness, in each
case if on the date of the incurrence of such Indebtedness, after giving effect
to the incurrence thereof, the Consolidated Fixed Charge Coverage Ratio of the
Company is greater than 2.0 to 1.0.

<PAGE>
                                     - 48 -

      SECTION 4.13. Limitation on Dividend and Other Payment Restrictions
Affecting Restricted Subsidiaries.

            The Company shall not, and shall not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary of the Company to (a) pay dividends or make
any other distributions on or in respect of its Capital Stock; (b) make loans or
advances or to pay any Indebtedness or other obligation owed to the Company or
any other Restricted Subsidiary of the Company; or (c) transfer any of its
property or assets to the Company or any other Restricted Subsidiary of the
Company, except for such encumbrances or restrictions existing under or by
reason of: (1) applicable law; (2) this Indenture; (3) customary non-assignment
provisions of any contract or lease governing a leasehold or ownership interest
of any Restricted Subsidiary of the Company; (4) any instrument governing
Acquired Indebtedness, which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person or the
properties or assets of the Person so acquired or relating to any property
acquired by the Company or any of its Restricted Subsidiaries after the Issue
Date, provided that such encumbrance or restriction exists of the time such
property is acquired, relates only to the property which is acquired and was not
incurred in connection with, or in anticipation or contemplation of, such
acquisition; (5) agreements existing on the Issue Date (including, without
limitation, the Credit Agreement) to the extent and in the manner such
agreements are in effect on the Issue Date; (6) an agreement governing
Indebtedness incurred to Refinance the Indebtedness issued, assumed or incurred
pursuant to an agreement referred to in clause (2), (4) or (5) above; provided,
however, that the provisions relating to such encumbrance or restriction
contained in any such Indebtedness are no less favorable to the Company in any
material respect than the provisions relating to such encumbrance or restriction
contained in agreements referred to in such clause (2), (4) or (5); or (7)
agreements restricting the sale or other disposition of any property securing
Indebtedness which constitutes a Permitted Lien on such property.

      SECTION 4.14. Prohibition on Incurrence of Senior Subordinated Debt.

            The Company shall not incur or suffer to exist Indebtedness that is
senior in right of payment to the Notes and

<PAGE>
                                     - 49 -

subordinate in right of payment to any other Indebtedness of the Company.

      SECTION 4.15. Change of Control.

            (a) Upon the occurrence of a Change of Control, the Company shall
make an offer to purchase all outstanding Notes pursuant to the offer described
in paragraph (b) below (the "Change of Control Offer") at a purchase price equal
to 101% of the principal amount thereof plus accrued interest, if any, to the
date of purchase, but installments of interest, the maturity of which is on or
prior to the Change of Control Payment Date, shall be payable to Holders of
record at the close of business on the relevant record dates referred to in
Section 2.12. Prior to the mailing of the notice referred to below, but in any
event within 30 days following any Change of Control, the Company shall (i)
repay in full and terminate all commitments under Indebtedness under the Credit
Agreement or offer to repay in full and terminate all commitments under all
Indebtedness under the Credit Agreement and to repay the Indebtedness owed to
each lender which has accepted such offer or (ii) obtain the requisite consents
under the Credit Agreement to permit the repurchase of the Notes as provided
below. The Company shall first comply with the covenant in the immediately
preceding sentence before it shall be required to repurchase Notes pursuant to
the provisions described in this Section 4.15. The Company's failure to comply
with the covenants described in this paragraph shall constitute an Event of
Default hereunder.

            (b) Within 30 days following the date upon which the Change of
Control occurred (the "Change of Control Date"), the Company shall send, by
first class mail, a notice to each Holder, with a copy to the Trustee, which
notice shall govern the terms of the Change of Control Offer. The notice to the
Holders shall contain all instructions and materials necessary to enable such
Holders to tender Notes pursuant to the Change of Control Offer. Such notice
shall state:

            (1) that the Change of Control Offer is being made pursuant to this
      Section 4.15 and that all Notes tendered and not withdrawn will be
      accepted for payment;

            (2) the purchase price (including the amount of accrued interest)
      and the purchase date (which shall be no earlier than 30 days nor later
      than 45 days from the date such notice is mailed, other than as may be
      required by law) (the "Change of Control Payment Date");

<PAGE>
                                     - 50 -

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

            (4) that, unless the Company defaults in making payment therefor,
      any Note 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 Note purchased pursuant to a
      Change of Control Offer will be required to surrender the Note, with the
      form entitled "Option of Holder to Elect Purchase" on the reverse of the
      Note completed, to the 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;

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

            (7) that Holders whose Notes are purchased only in part will be
      issued new Notes in a principal amount equal to the unpurchased portion of
      the Notes surrendered; provided that each Note purchased and each new Note
      issued shall be in an original principal amount of $1,000 or integral
      multiples thereof; and

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

            On or before the Change of Control Payment Date, the Company shall
(i) accept for payment Notes or portions thereof tendered pursuant to the
Change of Control Offer, (ii) deposit with the Paying Agent U.S. Legal Tender
sufficient to pay the purchase price plus accrued interest, if any, of all Notes
so tendered and (iii) forward to the Trustee Notes so accepted together with an
Officers' Certificate stating the Notes or portions thereof being purchased by
the Company. The Paying Agent shall promptly mail to the Holders of Notes so
accepted payment in an amount equal to the purchase price plus accrued interest,
if any, and the Trustee shall promptly authenticate and mail to such Holders new
Notes equal in principal amount to any unpurchased portion of the Notes
surrendered. Any Notes not so ac-

<PAGE>
                                     - 51 -

cepted shall be promptly mailed by the Company to the Holder thereof. For
purposes of this Section 4.15, the Trustee shall act as the Paying Agent.

            Any amounts remaining after the purchase of Notes pursuant to a
Change of Control Offer shall be returned by the Trustee to the Company.

            The Company shall comply with the requirements of Rule 14e-1 under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Change of Control Offer. To the extent the
provisions of any securities laws or regulations conflict with this Section
4.15, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 4.15 by virtue thereof.

      SECTION 4.16. Limitation on Asset Sales.

            (a) The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, consummate an Asset Sale unless (i) the Company or
the applicable Restricted Subsidiary, as the case may be, receives consideration
at the time of such Asset Sale at least equal to the fair market value of the
assets sold or otherwise disposed of (as determined in good faith by the
Company's Board of Directors); (ii) at least 7S% of the consideration received
by the Company or the Restricted Subsidiary, as the case may be, from such Asset
Sale shall be in the form of cash or Cash Equivalents (provided that the amount
of any liabilities (as shown on the Company's or such Restricted Subsidiary's
most recent balance sheet) of the Company or any such Restricted Subsidiary
(other than liabilities that are by their terms subordinated to the Notes) that
are assumed by the transferee of any such assets shall be deemed to be cash for
the purposes of this provision) and is received at the time of such disposition
or within 180 days thereafter; and (iii) upon the consummation of an Asset Sale,
the Company shall apply, or cause such Restricted Subsidiary to apply, the Net
Cash Proceeds relating to such Asset Sale within 365 days of receipt thereof
either (A) to prepay any Senior Debt or Indebtedness of a Wholly Owned
Restricted Subsidiary and, in the case of any Indebtedness under any revolving
credit facility, effect a permanent reduction in the availability under such
revolving credit facility, (B) to make an investment in properties and assets
that replace the properties and assets that were the subject of such Asset Sale
or in properties and assets that

<PAGE>
                                     - 52 -

will be used in the business of the Company and its Restricted Subsidiaries as
existing on the Issue Date or in businesses the same, similar or reasonably
related thereto ("Replacement Assets"), or (C) a combination of prepayment and
investment permitted by the foregoing clauses (iii) (A) and (iii) (B). Subject
to the last sentence of this paragraph, on the 366th day after an Asset Sale or
such earlier date, if any, as the Board of Directors of the Company or of such
Restricted Subsidiary determines not to apply the Net Cash Proceeds relating to
such Asset Sale as set forth in clause (iii) (A), (iii) (B) or (iii) (C) of the
next preceding sentence (each, a "Net Proceeds Offer Trigger Date"), such
aggregate amount of Net Cash Proceeds which have not been applied on or before
such Net Proceeds Offer Trigger Date as permitted in clauses (iii) (A), (iii)
(B) and (iii) (C) of the next preceding sentence (each a "Net Proceeds Offer
Amount") shall be applied by the Company or such Restricted Subsidiary to make
an offer to purchase (the "Net Proceeds Offer") on a date (the "Net Proceeds
Offer Payment Date") not less than 30 nor more than 45 days following the
applicable Net Proceeds Offer Trigger Date, from all Holders on a pro rata
basis, that amount of Notes equal to the Net Proceeds Offer Amount at a price
equal to 100% of the principal amount of the Notes to be purchased, plus accrued
and unpaid interest thereon, if any, to the date of purchase, but installments
of interest, the maturity of which is on or prior to the Proceeds Purchase Date,
shall be payable to Holders of record at the close of business on the relevant
record dates referred to in Section 2.12; provided, however, that if at any time
any non-cash consideration received by the Company or any Restricted Subsidiary
of the Company, as the case may be, in connection with any Asset Sale is
converted into or sold or otherwise disposed of for cash (other than interest
received with respect to any such non-cash consideration), then such conversion
or disposition shall be deemed to constitute an Asset Sale hereunder and the Net
Cash Proceeds thereof shall be applied in accordance with this covenant.

            The Company may defer the Net Proceeds Offer until there is an
aggregate unutilized Net Proceeds Offer Amount equal to or in excess of
$2,000,000 resulting from one or more Asset Sales (at which time, the entire
unutilized Net Proceeds Offer Amount, and not just the amount in excess of
$2,000,000, shall be applied as required pursuant to the preceding paragraph).

            In the event of the transfer of substantially all (but not all) of
the property and assets of the Company and its Restricted Subsidiaries as an
entirety to a Person in a trans-

<PAGE>
                                     - 53 -

action permitted under Section 5.01, the successor entity shall be deemed to
have sold such portion, if any, of the properties and assets of the Company and
its Restricted Subsidiaries not so transferred the fair market value of which
exceeds the fair market value (as determined in good faith by the Company's
Board of Directors) of the property and assets of such successor entity
immediately prior to consummation of such transaction for purposes of this
covenant, and shall comply with the provisions of this covenant with respect to
such deemed sale as if it were an Asset Sale. In addition, the fair market value
of such properties and assets of the Company or its Restricted Subsidiaries
deemed to be sold as aforesaid shall be deemed to be Net Cash Proceeds for
purposes of this Section 4.16.

            Each Net Proceeds Offer will be mailed to the record Holders as
shown on the register of Holders within 25 days following the Net Proceeds Offer
Trigger Date, with a copy to the Trustee, and shall comply with the procedures
set forth in this Indenture. Upon receiving notice of the Net Proceeds Offer,
Holders may elect to tender their Notes in whole or in part in integral
multiples of $1,000 in exchange for cash. To the extent Holders properly tender
Notes in an amount exceeding the Net Proceeds Offer Amount, Notes of tendering
Holders will be purchased on a pro rata basis (based on amounts tendered). To
the extent that the aggregate amount of Notes tendered pursuant to a Net
Proceeds Offer is less than the Net Proceeds Offer Amount, the Company may use
such excess Net Proceeds Offer Amount for general corporate purposes or for any
other purpose not prohibited by this Indenture. Upon completion of any such Net
Proceeds Offer, the Net Proceeds Offer Amount shall be reset at zero. A Net
Proceeds Offer shall remain open for a period of 20 Business Days or such longer
period as may be required by law.

            (b) Subject to the deferral of the Net Proceeds Offer Trigger Date
contained in the second paragraph of subsection (a) above, each notice of a Net
Proceeds Offer pursuant to this Section 4.16 shall be mailed or caused to be
mailed, by first class mail, by the Company not more than 25 days after the Net
Proceeds Offer Trigger Date to all Holders at their last registered addresses as
of a date within 15 days of the mailing of such notice, with a copy to the
Trustee. The notice shall contain all instructions and materials necessary to
enable such Holders to tender Notes pursuant to the Net Proceeds Offer and shall
state the following terms:

            (1) that the Net Proceeds Offer is being made pursuant to Section
      4.16 and that all Notes tendered will be

<PAGE>
                                     - 54 -

      accepted for payment; provided, however, that if the aggregate principal
      amount of Notes tendered in a Net Proceeds Offer exceeds the aggregate
      amount of the Net Proceeds Offer, the Company shall select the Notes to be
      purchased on a pro rata basis (with such adjustments as may be deemed
      appropriate by the Company so that only Notes in denominations of $1,000
      or multiples thereof shall be purchased);

            (2) the purchase price (including the amount of accrued interest)
      and the purchase date (which shall be 20 Business Days from the date of
      mailing of notice of such Net Proceeds Offer, or such longer period as
      required by law) (the "Proceeds Purchase Date");

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

            (4) that, unless the Company defaults in making payment therefor,
      any Note accepted for payment pursuant to the Net Proceeds Offer shall
      cease to accrue interest after the Proceeds Purchase Date;

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

            (6) that Holders will be entitled to withdraw their election if the
      Paying Agent receives, not later than two Business Days prior to the
      Proceeds Purchase Date, a telegram, telex, facsimile transmission or
      letter setting forth the name of the Holder, the principal amount of the
      Notes the Holder delivered for purchase and a statement that such Holder
      is withdrawing his election to have such Note purchased; and

            (7) that Holders whose Notes are purchased only in part will be
      issued new Notes in a principal amount equal to the unpurchased portion of
      the Notes surrendered; provided that each Note purchased and each new Note
      issued shall be in an original principal amount of $1,000 or integral
      multiples thereof;

<PAGE>
                                     - 55 -

            On or before the Proceeds Purchase Date, the Company shall (i)
accept for payment Notes or portions thereof tendered pursuant to the Net
Proceeds Offer which are to be purchased in accordance with item (b) (1) above,
(ii) deposit with the Paying Agent U.S. Legal Tender sufficient to pay the
purchase price plus accrued interest, if any, of all Notes to be purchased and
(iii) deliver to the Trustee Notes so accepted together with an Officers'
Certificate stating the Notes or portions thereof being purchased by the
Company. The Paying Agent shall promptly mail to the Holders of Notes so
accepted payment in an amount equal to the purchase price plus accrued interest,
if any. For purposes of this Section 4.16, the Trustee shall act as the Paying
Agent.

            Any amounts remaining after the purchase of Notes pursuant to a Net
Proceeds Offer shall be returned by the Trustee to the Company.

            The Company shall comply with the requirements of Rule 14e-l under
the Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable in connection with the
repurchase of Notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with this Section
4.16, the Company shall comply with the applicable securities laws and
regulations and shall not be deemed to have breached its obligations under this
Section 4.16 by virtue thereof.

      SECTION 4.17. Limitation on Preferred Stock of Restricted Subsidiaries.

            The Company shall not permit any of its Restricted Subsidiaries to
issue any Preferred Stock (other than to the Company or to a Wholly Owned
Restricted Subsidiary of the Company) or permit any Person (other than the
Company or a Wholly Owned Restricted Subsidiary of the Company) to own any
Preferred Stock of any Restricted Subsidiary of the Company.

      SECTION 4.18. Limitation on Liens.

            The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, create, incur, assume or suffer to exist any Liens of any kind
against or upon any of its property or assets of the Company or any of its
Restricted Subsidiaries whether owned on the Issue Date or acquired after the
Issue Date, or any proceeds therefrom, unless, except in the case of Liens
securing Indebtedness that is subordinate or junior in

<PAGE>
                                     - 56 -

right of payment to the Notes which shall not be permitted, the Notes are
equally and ratably secured, except for (A) Liens existing as of the Issue Date
to the extent and in the manner such Liens are in effect as of the Issue Date;
(B) Liens securing Senior Debt and Liens on assets of Restricted Subsidiaries
securing guarantees of Senior Debt; (C) Liens securing the Notes; (D) Liens of
the Company or a Wholly Owned Restricted Subsidiary of the Company on assets of
any Restricted Subsidiary of the Company; (E) Liens securing Refinancing
Indebtedness which is incurred to Refinance Indebtedness which has been secured
by a Lien permitted under this Indenture and which has been incurred in
accordance with the provisions of this Indenture; provided, however, that such
Liens (A) are no less favorable to the Holders and are no more favorable to the
lienholders with respect to such Liens than the Liens in respect of the
Indebtedness being Refinanced and (B) do not extend to or cover any property or
assets of the Company or any of its Restricted Subsidiaries not securing the
Indebtedness so Refinanced; and (F) Permitted Liens.

      SECTION 4.19. Limitation of Guarantees by Restricted Subsidiaries.

            The Company shall not permit any of its Restricted Subsidiaries,
directly or indirectly, by way of the pledge of any intercompany note or
otherwise, to assume, guarantee or in any other manner become liable with
respect to any Indebtedness of the Company or any other Restricted Subsidiary
(other than with respect to Permitted Indebtedness specified in clause (v),
(vi), (vii) or (viii) of the definition thereof), unless, in any such case (a)
such Restricted Subsidiary executes and delivers a supplemental indenture to
this Indenture providing a guarantee of payment of the Notes by such Restricted
Subsidiary (the "Guarantee") and (b) such assumption, guarantee or other
liability of such Restricted Subsidiary is provided in respect of Senior Debt,
and the guarantee or other instrument provided by such Restricted Subsidiary in
respect of such Senior Debt may be superior to the Guarantee pursuant to
subordination provisions no less favorable to the Holders of the Notes than
those contained in this Indenture.

            Notwithstanding the foregoing, any such Guarantee of the Notes by a
Restricted Subsidiary of the Company shall provide by its terms that it shall be
automatically and unconditionally released and discharged, without any further
action required on the part of the Trustee or any Holder, upon: (i) the
unconditional release of such Restricted Subsidiary from its liability in
respect of the Indebtedness in connection

<PAGE>
                                     - 57 -

with which such Guarantee was executed and delivered pursuant to the preceding
paragraph; or (ii) any sale or other disposition (by merger or otherwise) to any
Person which is not a Restricted Subsidiary of the Company, of all of the
Company's Capital Stock in, or all or substantially all of the assets of, such
Restricted Subsidiary; provided that (a) such sale or disposition of such
Capital Stock or assets is otherwise in compliance with the terms of this
Indenture and (b) such assumption, guarantee or other liability of such
Restricted Subsidiary has been released by the holders of the other Indebtedness
so guaranteed.

      SECTION 4.20. Limitation on Issuance of Shares of Restricted Subsidiaries.

            The Company shall not permit any of its Restricted Subsidiaries to
issue shares of Capital Stock (other than director's qualifying shares) to any
Person other than the Company or a Wholly Owned Restricted Subsidiary of the
Company; provided that (i) if the issuing Restricted Subsidiary is not a Wholly
Owned Restricted Subsidiary, the issuing Restricted Subsidiary may also
simultaneously issue additional shares of Capital Stock of the same class to
other shareholders of the issuing Restricted Subsidiary so long as such issuance
will not reduce the percentage of Capital Stock of the issuing Restricted
Subsidiary which was owned by the Company or its Restricted Subsidiaries
immediately prior to such issuance; and (ii) a Restricted Subsidiary may issue
Capital Stock to any Person to the extent that and subject to the conditions
under which the Company or another Restricted Subsidiary of the Company holding
the Capital Stock of such issuing Restricted Subsidiary would be permitted to
sell, transfer or otherwise dispose of such Capital Stock in an Asset Sale
pursuant to Section 4 16.

      SECTION 4.21. Conduct of Business.

            The Company shall not, and shall not permit its Restricted
Subsidiaries to, engage in any businesses which are not the same as, similar or
reasonably related to the businesses in which the Company and its Restricted
Subsidiaries are engaged on the Issue Date.

      SECTION 4.22. Consummation of Acquisition.

            No provision of this Indenture shall prevent the Company or any
Restricted Subsidiary thereof from consummating the Acquisition and the
transactions contemplated thereby.

                              SUCCESSOR CORPORATION

      SECTION 5.01. Merger, Consolidation and Sale of Assets.

            (a) The Company shall not, in a single transaction or a series of
related transactions, consolidate with or merge with or into any Person (other
than the merger of a Wholly Owned Restricted Subsidiary of the Company into the
Company), or sell, assign, transfer, lease, convey or otherwise dispose of (or
cause or permit any Restricted Subsidiary of the Company to sell, assign,
transfer, lease, convey or otherwise dispose of) all or substantially all of the
Company's properties and assets (determined on a consolidated basis for the
Company and its Restricted Subsidiaries) to any Person whether as an entirety or
substantially as an entirety unless:

            (1) either (A) the Company shall be the surviving or continuing
      corporation or (B) the Person (if other than the Company) formed by such
      consolidation or into which the Company is merged or the Person which
      acquires by sale, assignment, transfer, lease, conveyance or other
      disposition the properties and assets of the Company and its Restricted
      Subsidiaries substantially as an entirety (the "Surviving Entity") (x)
      shall be a corporation, partnership, limited liability company or business
      trust organized and validly existing under the laws of the United States
      or any State thereof or the District of Columbia and (y) shall expressly
      assume, by supplemental indenture (in form and substance reasonably
      satisfactory to the Trustee), executed and delivered to the Trustee, the
      due and punctual payment of the principal of and premium, if any, and
      interest on all of the Notes and the performance of every covenant of the
      Notes, this Indenture and, if applicable, the Registration Rights
      Agreement on the part of the Company to be performed or observed;

            (2) immediately after giving effect to such transaction and the
      assumption contemplated by clause (1) (B) (y) above (including giving
      effect to any Indebtedness and Acquired Indebtedness incurred or
      anticipated to be incurred in connection with or in respect of such
      transaction), the Company or such Surviving Entity, as the case may be,
      shall be able to incur at least $1.00 of additional In-

<PAGE>
                                     - 59 -

      debtedness (other than Permitted Indebtedness) in compliance with Section
      4.12;

            (3) immediately before and immediately after giving effect to such
      transaction and the assumption contemplated by clause (1) (B) (y) above
      (including, without limitation, giving effect to any Indebtedness and
      Acquired Indebtedness incurred or anticipated to be incurred and any Lien
      granted in connection with or in respect of the transaction), no Default
      or Event of Default shall have occurred and be continuing; and

            (4) the Company or the Surviving Entity, as the case may be, shall
      have delivered to the Trustee an Officers' Certificate and an Opinion of
      Counsel, each stating that such consolidation, merger, sale, assignment,
      transfer, lease, conveyance or other disposition and, if a supplemental
      indenture is required in connection with such transaction, such
      supplemental indenture comply with the applicable provisions of this
      Indenture and that all conditions precedent in this Indenture relating to
      such transaction have been satisfied.

            (b) For purposes of the foregoing, the transfer (by lease,
assignment, sale or otherwise, in a single transaction or series of
transactions) of all or substantially all of the properties and assets of one or
more Restricted Subsidiaries of the Company, the Capital Stock of which
constitutes all or substantially all of the properties and assets of the
Company, shall be deemed to be the transfer of all or substantially all of the
properties and assets of the Company.

            Notwithstanding the foregoing, this Section shall not prohibit a
transaction, the principal purpose of which is (as determined in good faith by
the Board of Directors of the Company) to change the state of incorporation of
the Company and such transaction does not have as one of its purposes the
evasion of the limitations imposed by this Section.

            When a successor assumes all of the obligations of the Company under
the Notes and this Indenture in a transaction permitted by this Section 5.01,
the Company will be deemed to be released from those obligations.

      SECTION 5.02. Successor Corporation Substituted.

            Upon any consolidation, combination or merger or any transfer of all
or substantially all of the assets of the Com-

<PAGE>
                                     - 60 -

pany in accordance with the foregoing, in which the Company is not the
continuing corporation, the successor Person formed by such consolidation or
into which the Company is merged or to which such conveyance, lease or transfer
is made shall succeed to, and be substituted for, and may exercise every right
and power of, the Company under this Indenture and the Notes with the same
effect as if such surviving entity had been named as such.

            (1) failure to pay interest on any Notes when the same becomes due
      and payable and the Default continues for a period of 20 days (whether or
      not such payment shall be prohibited by Article Ten of this Indenture); or

            (2) failure to pay the principal on any Notes when such principal
      becomes due and payable, at maturity, upon redemption or otherwise
      (including the failure to make a payment to purchase Notes tendered
      pursuant to a Change of Control Offer or a Net Proceeds Offer) (whether or
      not such payment shall be prohibited by Article Ten); or

            (3) a default in the observance or performance of any other covenant
      or agreement contained in this Indenture which default continues for a
      period of 30 days after the Company receives written notice specifying the
      default (and demanding that such default be remedied) from the Trustee or
      the Holders of at least 25% of the outstanding principal amount of the
      Notes (except in the case of a failure to comply with Section 4.10,
      Section 4.12 or Section 5.01, which shall constitute Events of Default
      upon notice but without passage of time); or

            (4) the Company fails to pay at final stated maturity (giving effect
      to any applicable grace periods and any extensions thereof) the principal
      amount of any Indebtedness for borrowed money of the Company or any
      Restricted Subsidiary of the Company or interest thereon, or the ac-

<PAGE>
                                     - 61 -

      celeration of the final stated maturity of any such Indebtedness if the
      aggregate principal amount of such Indebtedness, together with the
      principal amount of any other such Indebtedness not paid at final stated
      maturity or which has been accelerated aggregates $2,000,000 or more at
      any time; or

            (5) one or more judgments for the payment of money in an aggregate
      amount in excess of $2,000,000 shall have been rendered against the
      Company or any of its Restricted Subsidiaries and such judgments remain
      undischarged, unpaid or unstayed for a period of 60 days after such
      judgment or judgments become final and non-appealable; or

            (6) the Company or any Significant Subsidiary of the Company (A)
      commences a voluntary case or proceeding under any Bankruptcy Law with

      order for relief against it in an involuntary case or proceeding under any
      Bankruptcy Law, (C) consents to the appointment of a Custodian of it or
      for substantially all of its property, (D) consents to or acquiesces in
      the institution of a bankruptcy or an insolvency proceeding against it,

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

            (7) a court of competent jurisdiction enters a judgment, decree or
      order for relief in respect of the Company or any Significant Subsidiary
      of the Company in an involuntary case or proceeding under any Bankruptcy
      Law, which shall (A) approve as properly filed a petition seeking
      reorganization, arrangement, adjustment or composition in respect of the
      Company or any such Significant Subsidiary, (B) appoint a Custodian of the
      Company or any such Significant Subsidiary or for substantially all of its
      property or (C) order the winding-up or liquidation of its affairs; and
      such judgment, decree or order shall remain unstayed and in effect for a
      period of 60 consecutive days; or

            (8) the lenders under the Credit Agreement commence proceedings to
      foreclose upon any assets of the Company or any of its Restricted
      Subsidiaries as a result of a default with respect to Obligations of at
      least $2,000,000; or

            (9) any Guarantee ceases to be in full force and effect or any
      Guarantee is declared to be null and void and

<PAGE>
                                     - 62 -

      unenforceable or any Guarantee is found to be invalid or any guarantor
      denies its liability under its Guarantee (other than by reason of release
      of a Guarantee in accordance with Section 4.19).

      SECTION 6.02. Acceleration.

            (a) If an Event of Default (other than an Event of Default specified
in Section 6.01(6) or (7) with respect to the Company) occurs and is continuing
and has not been waived pursuant to Section 6.04, then the Trustee or the
Holders of at least 25% in principal amount of outstanding Notes may declare the
principal of and accrued interest on all the Notes to be due and payable by
notice in writing to the Company and the Trustee specifying the respective Event
of Default and that it is a "notice of acceleration" (the "Acceleration
Notice"), and the same (i) shall become immediately due and payable or (ii) if
there are any amounts or letters of credit outstanding under the Credit
Agreement, shall become immediately due and payable upon the first to occur of
an acceleration under the Credit Agreement or five business days after receipt
by the Company and the Representative under the Credit Agreement of such
Acceleration Notice but only if such Event of Default is then continuing. Upon
any such declaration, but subject to the immediately preceding sentence, such
amount shall be immediately due and payable.

            (b) If an Event of Default specified in Section 6.01(6) or (7)
occurs and is continuing with respect to the Company, all unpaid principal of
and premium, if any, and accrued and unpaid interest on all of the outstanding
Notes 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.

            (c) At any time after a declaration of acceleration with respect to
the Notes in accordance with Section 6.02(a), the Holders of a majority in
principal amount of the Notes may, on behalf of the Holders of all of the Notes,
rescind and cancel such declaration and its consequences (i) if the rescission
would not conflict with any judgment or decree, (ii) 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, (iii) to the extent the
payment of such interest is lawful, interest on overdue installments of interest
and overdue principal, which has become due otherwise than by such declaration
of acceleration, has been paid, (iv) if the Company has paid the Trustee its
reasonable compensation

<PAGE>
                                     - 63 -

and reimbursed the Trustee for its expenses, disbursements and advances and (v)
in the event of the cure or waiver of an Event of Default of the type described
in Section 6.01(6) or (7), 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. The Holders of a majority in principal amount of the
Notes may waive any existing Default or Event of Default under this Indenture,
and its consequences, except a default in the payment of the principal of or
interest on any Notes.

      SECTION 6.03. Other Remedies.

            If an Event of 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 Notes or to enforce the performance
of any provision of the Notes or this Indenture.

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

      SECTION 6.04. Waiver of Past Defaults.

            Subject to Sections 2.09, 6.07 and 9.02, the Holders of a majority
in principal amount of the outstanding Notes by notice to the Trustee may waive
an existing Default or Event of Default and its consequences, except a Default
in the payment of principal (other than principal due by reason of acceleration)
of or interest on any Note as specified in clauses (l) and (2) of Section 6.01.
When a Default or Event of Default is waived, it is cured and ceases.

      SECTION 6.05. Control by Majority.

            Subject to Section 2.09, the Holders of a majority in principal
amount of the outstanding Notes 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, including, without limitation, any remedies
provided for in Section 6.03. Subject to Section 7.01, however,

<PAGE>
                                     - 64 -

the Trustee may refuse to follow any direction that the Trustee reasonably
believes conflicts with any law or this Indenture, that the Trustee determines
may be unduly prejudicial to the rights of another Holder, or that may involve
the Trustee in personal liability; provided that the Trustee may take any other
action deemed proper by the Trustee which is not inconsistent with such
direction; and provided further that this provision shall not affect the rights
of the Trustee set forth in Section 7.01(d).

      SECTION 6.06. Limitation on Suits.

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

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

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

            (3) such Holders offer to the Trustee indemnity in its sole
      discretion satisfactory to the Trustee against any loss, liability or
      expense to be incurred in compliance with such request;

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

            (5) during such 45-day period the Holders of a majority in principal
      amount of the outstanding Notes 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 Note, on or
after the respective due dates expressed in such Note, or to bring suit for the
enforcement of

<PAGE>
                                     - 65 -

any such payment on or after such respective dates, shall not be impaired or

      SECTION 7.01. Duties of Trustee.

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

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

            (1) The Trustee need perform only those duties as are specifically
      set forth in this Indenture and no covenants 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 or opinions furnished
      to the Trustee and conforming to the requirements of this Indenture.
      However, the Trustee 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 contained, 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 Trust Officer, unless it is proved that the Trustee was

      takes or omits to take in good faith in accordance with a direction

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

            (e) Whether or not herein expressly provided, every provision of
this Indenture that in any way relates to the Trustee is subject to paragraphs
(a), (b), (c) and (d) of this Section 7.01.

            Subject to Section 7.01:

            (a) The Trustee may rely and shall be fully protected in acting or
      refraining from acting upon any resolution, certificate, statement,
      instrument, opinion, report, notice, request, direction, consent, order,
      bond, note or other paper or 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.

            (b) Before the Trustee acts or refrains from acting, it may consult
      with counsel and may require an Officers' Certificate, an Opinion of
      Counsel or both, which shall conform to Sections 11.04 and 11.05. The
      Trustee shall not be liable for any action it takes or omits to take in
      good faith in reliance on such Officers' Certificate or Opinion of
      Counsel.

      perform any duties hereunder either directly or indirectly or by or

      the facts or matters stated in any resolution, certificate, statement,

      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 Company, to examine the books, records, and premises of the
      Company, personally or by agent or attorney and to consult with the
      officers and representatives of the Company, including the Company's
      accountants and attorneys.

            (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

rights. However, the Trustee must comply with Sections 7.10 and 7.11.

      SECTION 7.04. Trustee's Disclaimer.

            The recitals contained herein and in the Notes shall be taken as
statements of the Company and the Trustee assumes no responsibility for their

<PAGE>
                                     - 70 -

representation as to the validity or adequacy of this Indenture or the Notes,
and it shall not be accountable for the Company's use of the proceeds from the
Notes, and it shall not be responsible for any statement of the Company in this
Indenture or the Notes other than the Trustee's certificate of authentication.

      SECTION 7.05. Notice of Default.

            If a Default or an Event of Default occurs and is continuing and if
it is known to the Trustee, the Trustee shall mail to each Holder notice of the
uncured Default or Event of Default within 90 days after such Default or Event
of Default occurs. Except in the case of a Default or an Event of Default in
payment of principal of, or interest on, any Note, 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 on the Proceeds Purchase Date pursuant
to a Net Proceeds Offer and, except in the case of a failure to comply with
Article Five hereof, the Trustee may withhold the notice if and so long as its
Board of Directors, the executive committee of its Board of Directors or a
committee of its directors and/or Trust Officers 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, the Trustee shall, to the extent
that any of the events described in TIA ss. 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 ss. 313(a). The Trustee also shall comply with
TIA ss.ss. 313(b), (c) and (d).

            A copy of each report at the time of its mailing to Holders shall be
mailed to the Company and filed with the SEC and each stock exchange, if any, on
which the Notes are listed.

            The Company shall promptly notify the Trustee if the Notes become
listed on any stock exchange and the Trustee shall comply with TIA ss. 313(d).

      SECTION 7.07. Compensation and Indemnity.

            The Company shall pay to the Trustee from time to time reasonable
compensation for its services. The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee upon request for all reasonable fees and expenses, in-

<PAGE>
                                     - 71 -

cluding reasonable out-of-pocket expenses incurred or made by it in connection
with the performance of its duties under this Indenture. Such expenses shall
include the reasonable fees and expenses of the Trustee's agents, consultants
and counsel.

            The Company shall indemnify the Trustee and its agents, employees,
stockholders and directors and officers for, and hold them harmless against, any
loss, 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 administration of this trust including
the reasonable costs and expenses of defending themselves against any claim or
liability in connection with the exercise or performance of any of their rights,
powers or duties hereunder. The Trustee shall notify the Company promptly of any
claim asserted against the Trustee for which it may seek indemnity. At the
Trustee's sole discretion, the Company shall defend the claim and the Trustee
shall cooperate and may participate in the defense; provided that any settlement
of a claim shall be approved in writing by the Trustee. Alternatively, the
Trustee may at its option have separate counsel of its own choosing and the
Company shall pay the reasonable fees and expenses of such counsel; provided
that the Company will not be required to pay such fees and expenses if it
assumes the Trustee's defense and there is no conflict of interest between the
Company and the Trustee in connection with such defense as reasonably determined
by the Trustee. The Company need not pay for any settlement made without its
written consent. The Company 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 Company's payment obligations in this Section 7.07,
the Trustee shall have a lien prior to the Notes on all assets or money held or
collected by the Trustee, in its capacity as Trustee, except assets or money
held in trust to pay principal of or interest on particular Notes. The Trustee's
right to receive payment of any amounts due under this Section 7.07 shall not be
subordinate to any other liability or indebtedness of the Company (even though
the Notes may be subordinate to such other liability or indebtedness).

            When the Trustee incurs expenses or renders services after an Event
of Default specified in Section 6.01(6) or (7) occurs, such expenses and the
compensation for such services are intended to constitute expenses of
administration under any Bankruptcy Law; provided, however, that this shall not
affect

<PAGE>
                                     - 72 -

the Trustee's rights as set forth in the preceding paragraph or Section 6.10.

      SECTION 7.08. Replacement of Trustee.

            A resignation or removal of the Trustee and appointment of a
successor Trustee shall become effective only upon the successor Trustee's
acceptance of appointment as provided in this Section 7.08.

majority in principal amount of the outstanding Notes may remove the Trustee by
so notifying the Company and the Trustee and may appoint a successor Trustee.

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

            (2) the Trustee is adjudged bankrupt or insolvent;

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

            (4) the Trustee 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 Company 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 Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Company.

            A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Immediately after that,
the retiring Trustee shall transfer 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 Company or the
Holders of at least 10% in principal amount of the outstanding Notes may
petition any

court of competent jurisdiction for the appointment of a successor Trustee.

            If the Trustee fails to comply with Section 7.10, any 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 Company's obligations under Section 7.07 hereof shall continue for the
benefit of the retiring Trustee in connection with the rights and duties
hereunder prior to such replacement.

      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 ss. ss. 310(a) (1), (2) and (5). The Trustee (or, in the case
of a corporation included in a bank holding company system, the related bank
holding company) shall have a combined capital and surplus of at least $100
million 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 such bank holding company, shall meet the
capital requirements of TIA ss. 310(a)(2). The Trustee shall comply with TIA ss.
310(b); provided, however, that there shall be excluded from the operation of
TIA ss. 310(b) (1) any indenture or indentures under which other securities, or
certificates of interest or participation in other securities, of the Company
are outstanding, if the requirements for such exclusion set forth in TIA ss.
310(b) (1) are met. The provisions of TIA ss. 310 shall apply to the Company, as
obligor of the Notes.

      SECTION 7.11. Preferential Collection of Claims Against Company.

            The Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been
removed shall be subject to TIA ss. 311(a) to the extent indicated therein. The
provisions of TIA ss. 311 shall apply to the Company, as obligor on the Notes.

for whose payment U.S. Legal Tender has theretofore been deposited with the
Trustee or the Paying Agent in trust or segregated and held in trust by the
Company and thereafter repaid to the Company, as provided in Section 8.05) have
been delivered to the Trustee for cancellation and the Company has paid all sums

      satisfactory to the Trustee, as trust funds in trust solely for the
      benefit of the Holders for that purpose, U.S. Legal Tender in such amount
      as is sufficient without consideration of reinvestment of such interest,
      U.S. Government Obligations which through the scheduled payment of
      principal and interest in respect thereof in accordance with their terms,
      will provide, not later than one day before the due date

<PAGE>
                                     - 75 -

      of any payment on the Notes, U.S. Legal Tender, or a combination thereof,
      in such amounts as will be sufficient, in the opinion of a nationally
      recognized firm of independent public accountants, to pay principal of,
      premium, if any, and interest on the outstanding Notes, on the dates on
      which such payments are due and payable in accordance with the terms of
      this Indenture, to maturity or redemption; provided that the Trustee shall
      have been irrevocably instructed to apply such U.S. Legal Tender to the
      payment of said principal, premium, if any, and interest with respect to
      the Notes and, provided, further, that from and after the time of deposit,
      the money deposited shall not be subject to the rights of holders of
      Senior Debt pursuant to the provisions of Article Ten;

      the Notes shall have occurred and be continuing on the date of such
      deposit or shall occur as a result of such deposit and such deposit will
      not result in a breach or violation of, or constitute a default under, any
      other instrument to which the Company is a party or by which it is bound;

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

            (e) the Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent providing for or relating to the termination of the Company's
      obligations under the Notes 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 (if then
      in effect) or any other agreement or instrument then known to such counsel
      that binds or affects the Company.

            Notwithstanding the foregoing paragraph, the Company's obligations
in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02, 7.07, 8.05 and 8.06 shall

"Covenant Defeasance"), and the Notes 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 Notes shall not be deemed outstanding
for accounting purposes) and Holders of the Notes and any amounts deposited
under Section 8.03 hereof shall cease to be subject to any obligations to, or
the rights of, any holder of Senior Debt under Article Ten or otherwise. For
this purpose, such Covenant Defeasance means that, with respect to the
outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event or Default under Section
6.01(3) hereof, but, except as specified above, the remainder of this Indenture
and such Notes shall be unaffected thereby. In addition, upon the Company's
exercise under 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, Sections 6.01(3), 6.01(4), 6.01(5), 6.01(6) (solely with respect to
Persons other than the Company) or 6.01(7) (solely with respect to Persons other
than the Company) shall not constitute Defaults or 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 Notes:

      In order to exercise either Legal Defeasance or Covenant Defeasance:

            (a) the Company must irrevocably deposit with the Trustee, in trust,
      for the benefit of the Holders, U.S. Legal Tender or U.S. Government
      Obligations which through the scheduled payment of principal and interest
      in respect thereof in accordance with their terms, will provide, not later
      than one day before the due date of any payment on the Notes, U.S. Legal
      Tender, or a combination thereof, in such amounts as will be sufficient,
      in the opinion of a

<PAGE>
                                      -78-

      nationally recognized firm of independent public accountants, to pay the
      principal of, premium, if any, and interest on the Notes on the stated
      date for payment thereof or on the applicable redemption date, as the case
      may be, of such principal or installment of principal of or interest on
      the Notes; provided that the Trustee shall have received an irrevocable
      written order from the Company instructing the Trustee to apply such U.S.
      Legal Tender or the proceeds of such U.S. Government Obligations to said
      payments with respect to the Notes;

            (b) in the case of an election under Section 8.02(b) hereof, the
      Company shall have delivered to the Trustee an Opinion of Counsel in the
      United States reasonably acceptable to the Trustee confirming that (A) the
      Company has received from, or there has been published by, the Internal
      Revenue Service a ruling or (B) since the date of this Indenture, there
      has been a change in the applicable federal income tax law, in either case
      to the effect that, and based thereon such Opinion of Counsel shall
      confirm that, the Holders of the Notes 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;

            (c) in the case of an election under Section 8.02(c) hereof, the
      Company shall have delivered to the Trustee an Opinion of Counsel in the
      United States reasonably acceptable to the Trustee confirming that the
      Holders of the Notes 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;

            (d) no Default or Event of Default or event which with notice or
      lapse of time or both would become a Default or an Event of Default with
      respect to the Notes shall have occurred and be continuing (x) on the date
      of such deposit (other than a Default or Event of Default resulting from
      the incurrence of Indebtedness all or a portion of the proceeds of which
      will be used to defease the Notes pursuant to this Article Eight
      concurrently with such incurrence) or (y) insofar as Sections 6.01(6) and

<PAGE>
                                      -79-

      6.01(7) hereof are concerned, at any time in the period ending on the 91st
      day after the date of such deposit;

            (e) such Legal Defeasance or Covenant Defeasance shall not result in
      a breach or violation of or constitute a default under this Indenture or
      any other material agreement or instrument to which the Company or any of
      its Subsidiaries is a party or by which the Company or any of its
      Subsidiaries is bound;

            (f) the Company shall have delivered to the Trustee an Officers'
      Certificate stating that the deposit was not made by the Company with the
      intent of preferring the Holders over any other creditors of the Company
      or with the intent of defeating, hindering, delaying or defrauding any
      other creditors of the Company or others;

            (g) the Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for or relating to the Legal Defeasance or the Covenant
      Defeasance have been complied with (other than the condition in clause (d)
      (y)); and

            (h) the Company shall have delivered to the Trustee an Opinion of
      Counsel substantially to the effect that (i) the trust funds will not be
      subject to any rights of any holders of Senior Debt, including, without
      limitation, those arising under this Indenture, and (ii) assuming no
      intervening bankruptcy or insolvency of the Company between the date of
      deposit and the 91st day following the deposit and that no Holder is an
      insider of the Company, after the 91st day following the deposit, the
      trust funds will not be subject to the effect of any applicable Bankruptcy
      Law.

      SECTION 8.04. Application of Trust Money.

            The Trustee or Paying Agent shall hold in trust U.S. Legal Tender or
U.S. Government Obligations deposited with it pursuant to Article Eight, and
shall apply the deposited U.S. Legal Tender and the money from U.S. Government
Obligations in accordance with this Indenture to the payment of principal of and
interest on the Notes. The Trustee shall be under no obligation to invest said
U.S. Legal Tender or U.S. Government Obligations except as it may agree with the
Company.

<PAGE>
                                      -80-

            The Company 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 Obligations deposited pursuant to Section 8.03 hereof 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 Notes.

            Anything in this Article Eight to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the Company's
request any U.S. Legal Tender or U.S. Government Obligations held by it as
provided in Section 8.03 hereof 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 Company.

            Subject to Article Eight, the Trustee and the Paying Agent shall
promptly pay to the Company upon request any excess U.S. Legal Tender or U.S.
Government Obligations 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 Company 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 Company 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
Company. After payment to the Company, Holders entitled to such money must look
to the Company 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 Obligations in accordance with 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

<PAGE>
                                      -81-

application, the Company's obligations under this Indenture and the Notes shall
be revived and reinstated as though no deposit had occurred pursuant to Article
Eight until such time as the Trustee or Paying Agent is permitted to apply all
such U.S. Legal Tender or U.S. Government Obligations in accordance with Article
Eight; provided that if the Company has made any payment of interest on or
principal of any Notes because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Notes to
receive such payment from the U.S. Legal Tender or U.S. Government Obligations
held by the Trustee or Paying Agent.

                                  ARTICLE NINE

                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

      SECTION 9.01. Without Consent of Holders.

            The Company, when authorized by a Board Resolution, and the Trustee,
together, may amend or supplement this Indenture or the Notes without notice to
or consent of any Holder:

            (1) to cure any ambiguity, defect or inconsistency; provided that
      such amendment or supplement does not, in the opinion of the Trustee,
      adversely affect the rights of any Holder in any material respect;

            (2) to comply with Article Five;

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

            (4) to comply with any requirements of the SEC in order to effect or
      maintain the qualification of this Indenture under the TIA;

            (5) to make any change that would provide any additional benefit or
      rights to the Holders or that does not adversely affect the rights of any
      Holder; or

            (6) to make any other change that does not, in the opinion of the
      Trustee, adversely affect in any material respect the rights of any
      Holders hereunder;

<PAGE>
                                      -82-

provided that the Company has delivered to the Trustee an Opinion of Counsel
stating that such amendment or supplement complies with the provisions of this
Section 9.01.

      SECTION 9.02. With Consent of Holders.

            (a) Subject to Section 6.07, the Company, when authorized by a Board
Resolution, 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
Notes, may amend or supplement this Indenture or the Notes, without notice to
any other Holders. Subject to Section 6.07, the Holder or Holders of a majority
in aggregate principal amount of the outstanding Notes may waive compliance by
the Company with any provision of this Indenture or the Notes without notice to
any other Holder.

            (b) No amendment, supplement or waiver, including a waiver pursuant
to Section 6.04, shall, without the consent of each Holder of each Note affected
thereby:

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

            (2) reduce the rate of or change or have the effect of changing the
      time for payment of interest, including defaulted interest, on any Notes;

            (3) reduce the principal of or change or have the effect of changing
      the fixed maturity of any Notes, or change the date on which any Notes may
      be subject to redemption or repurchase, or reduce the redemption or
      repurchase price therefor;

            (4) make any Notes payable in money other than that stated in the
      Notes;

            (5) make any change in provisions of this Indenture protecting the
      right of each Holder to receive payment of principal of and interest on
      such Note on or after the due date thereof or to bring suit to enforce
      such payment, or permitting Holders of a majority in principal amount of
      Notes to waive Defaults or Events of Default, other than ones with respect
      to the payment of principal of or interest on the Notes;

            (6) amend, modify, change or waive any provision of this Section
      9.2;

<PAGE>
                                      -83-

            (7) amend, modify or change in any material respect the obligation
      of the Company to make or consummate a Change of Control Offer in the
      event of a Change of Control or make and consummate a Net Proceeds Offer
      in respect of any Asset Sale that has been consummated or modify any of
      the provisions or definitions with respect thereto after a Change of
      Control has occurred or the subject Asset Sale has been consummated; or

            (8) modify Article Ten or the definitions used in Article Ten to
      adversely affect the Holders of the Notes in any material respect.

            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.

            After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture.

      SECTION 9.03. Effect on Senior Debt.

            No amendment of this Indenture shall adversely affect the rights of
any holder of Senior Debt under Article Ten of this Indenture, without the
consent of such holder.

      SECTION 9.04. Compliance with TIA.

            Every amendment, waiver or supplement of this Indenture or the Notes
shall, except as may otherwise be provided in any order of the SEC pursuant to
TIA ss 304(d), comply with the TIA as then in effect.

      SECTION 9.05. Revocation and Effect of Consents.

            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 Note or portion of a Note that evidences the same debt as
the consenting Holder's Note, even if notation of the consent is not made on any
Note. Subject to the following paragraph, any such Holder or subsequent Holder
may revoke the consent as to such Holder's Note or

<PAGE>
                                     - 84 -

portion of such Note by notice to the Trustee or the Company received before the
date on which the Trustee receives an Officers' Certificate certifying that the
Holders of the requisite principal amount of Notes have consented (and not
theretofore revoked such consent) to the amendment, supplement or waiver.

            The Company 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 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 Holders 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.

            After an amendment, supplement or waiver becomes effective, it shall
bind every Holder, unless it makes a change described in any of clauses (1)
through (8) of Section 9.02(b), in which case, the amendment, supplement or
waiver shall bind only each Holder of a Note who has consented to it and every
subsequent Holder of a Note or portion of a Note that evidences the same debt as
the consenting Holder's Note.

      SECTION 9.06. Notation on or Exchange of Notes.

            If an amendment, supplement or waiver changes the terms of a Note,
the Trustee may require the Holder of such Note to deliver it to the Trustee.
The Trustee may place an appropriate notation on the Note about the changed
terms and return it to the Holder. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Note shall issue and the Trustee
shall authenticate a new Note that reflects the changed terms. Any such notation
or exchange shall be made at the sole cost and expense of the Company.

      SECTION 9.07. Trustee To Sign Amendments, Etc.

            The Trustee shall execute any amendment, supplement or waiver
authorized or permitted 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

<PAGE>
                                      -85-

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. Such Opinion of Counsel shall not be an expense of
the Trustee.

                                   ARTICLE TEN

                                  SUBORDINATION

      SECTION 10.01. Notes Subordinated to Senior Debt.

            The Company covenants and agrees, and each Holder of the Notes, by
its acceptance thereof, likewise covenants and agrees, that all Notes shall be
issued subject to the provisions of this Article Ten; and each Person holding
any Note, whether upon original issue or upon transfer, assignment or exchange
thereof, accepts and agrees that the payment of all Obligations on the Notes by
the Company shall, to the extent and in the manner herein set forth, be
subordinated and junior in right of payment to the prior payment in full in cash
or Cash Equivalents of all Obligations on the Senior Debt; that the
subordination is for the benefit of, and shall be enforceable directly by, the
holders of Senior Debt, and that each holder of Senior Debt whether now
outstanding or hereafter created, incurred, assumed or guaranteed shall be
deemed to have acquired Senior Debt in reliance upon the covenants and
provisions contained in this Indenture and the Notes; provided however that the
Indebtedness represented by the Notes shall cease to be so subordinate, junior
and subject in right of payment upon any defeasance thereof in accordance with
Article Eight.

      SECTION 10.02. No Payment on Notes in Certain Circumstances.

            (a) Unless Section 10.03 shall be applicable, if any default occurs
and is continuing in the payment when due, whether at maturity, upon redemption,
by declaration or otherwise, of any principal of, interest on, unpaid drawings
for letters of credit issued in respect of, or regularly accruing fees with
respect to, any Senior Debt, and such default shall not have ceased to exist or
have been cured or waived by or on behalf of the holders of such Senior Debt, no
payment of any kind or character (other than payments by a trust previously
established pursuant to Article Eight), by set-off or other

<PAGE>
                                      -86-

wise, shall be made by, or on behalf of, the Company or any other Person on its
or their behalf with respect to any Obligations on the Notes, or to acquire any
of the Notes for cash or property or otherwise, in each case, other than
payments in Junior Securities. In addition, unless Section 10.03 shall be
applicable, if any other event of default occurs and is continuing with respect
to any Senior Debt, as such event of default is defined in the instrument
creating or evidencing such Senior Debt, permitting the holders of such Senior
Debt then outstanding to accelerate the maturity thereof and if the
Representative for the Senior Debt gives notice of the event of default to the
Trustee (a "Default Notice"), then, unless and until all events of default have
been cured or waived or have ceased to exist or the Trustee receives notice
thereof from the Representative for the respective issue of Senior Debt
terminating the Blockage Period (as defined below), during the 179 days after
the delivery of such Default Notice (the "Blockage Period"), neither the Company
nor any other Person on its behalf shall (x) make any payment of any kind or
character (other than payments by a trust previously established pursuant to
Article Eight), by set-off or otherwise, with respect to any Obligations on the
Notes or (y) acquire any of the Notes for cash or property or otherwise, in each
case, other than payments in Junior Securities. Notwithstanding anything herein
to the contrary, in no event will a Blockage Period extend beyond 179 days from
the date the payment on the Notes was due and only one such Blockage Period may
be commenced within any 360 consecutive days. No event of default which existed
or was continuing on the date of the commencement of any Blockage Period with
respect to the Senior Debt shall be, or be made, the basis for the commencement
of a second Blockage Period by the Representative of the 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 commencing after the date of commencement of such
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).

            (b) In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee or any Holder when such payment is prohibited
by Section 10.02(a), such payment 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

<PAGE>
                                      -87-

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 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
Company 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 Notes to take any action to accelerate the maturity of
the Notes pursuant to Section 6.02 or to pursue any rights or remedies
hereunder.

      SECTION 10.03. Payment Over of Proceeds upon Dissolution, Etc.

            (a) Upon any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to creditors upon
any total or partial liquidation, dissolution, winding-up, reorganization,
assignment for the benefit of creditors or marshaling of assets of the Company
or in a bankruptcy, reorganization, insolvency, receivership or other similar
proceeding relating to the Company or its property, 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 (other than payments by a trust previously
established pursuant to Article Eight) is made on account of any Obligations on
the Notes, or for the acquisition of any of the Notes for cash or property or
otherwise, other than payments or distributions in Junior Securities. Upon any
such dissolution, winding-up, liquidation, reorganization, receivership or
similar proceeding, any payment or distribution of assets of the Company of any
kind or character (other than payments by a trust previously established
pursuant to Article Eight), whether in cash, property or securities, other than
payments or distributions in Junior Securities, to which the Holders of the
Notes or the Trustee under this Indenture would be entitled, except for the
provisions of this Article Ten, shall be paid by the Company 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

<PAGE>
                                      -88-

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.

            (b) To the extent any payment of Senior Debt (whether by or on
behalf of the Company, 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, if such payment is recovered by, or
paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent
or other similar Person, 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.

            (c) In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character (other than
payments by a trust previously established pursuant to Article Eight), whether
in cash, property or securities, other than in Junior Securities, shall be
received by any Holder when such payment or distribution is prohibited by this
Section 10.03(c), 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 thereof or to or for the holders of such
Senior Debt.

            (d) The consolidation of the Company with, or the merger of the
Company with or into, another corporation or the liquidation or dissolution of
the Company following the conveyance or transfer of all or substantially all of
its assets, to another corporation upon the terms and conditions provided in

reorganization for the purposes of this Section if such other corporation shall,
as a part of such consolidation, merger, conveyance or transfer, assume the
Company's obligations hereunder in accordance with Article Five hereof.

      SECTION 10.04. Payments May Be Paid Prior to Dissolution.

            Nothing contained in this Article Ten or elsewhere in this Indenture
shall prevent (i) the Company, except under the conditions described in Sections

payments of principal of and interest on the Notes, 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 Notes 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 Trust Officer
shall have actually received the written notice provided for in the second
sentence of Section 10.02(a) or in Section 10.07. The Company shall give prompt

securities of the Company applicable to the Senior Debt until the Notes 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 Company
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 Company and the
Holders of the Notes, be deemed to be a payment by the Company 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 of the Notes, on the one hand, and the holders of the Senior Debt,
on the other hand.

                                      -90-

      SECTION 10.06. Obligations of the Company Unconditional.

            Nothing contained in this Article Ten or elsewhere in this Indenture
or in the Notes is intended to or shall impair, as among the Company, its
creditors other than the holders of Senior Debt, and the Holders, the obligation
of the Company, which is absolute and unconditional, to pay to the Holders the
principal of and any interest on the Notes 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 Company other than the
holders of the Senior Debt, nor shall anything herein or therein prevent the
Holder of any Note 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, property or securities of the Company
received upon the exercise of any such remedy.

      SECTION 10.07. Notice to Trustee.

            The Company shall give prompt written notice to the Trustee of any
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Notes pursuant to the provisions of this
Article Ten. 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 Company, or from a holder of Senior Debt or a
Representative therefor, together with proof satisfactory to the Trustee of
such holding of Senior Debt or of the authority of such Representative, 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.

            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
reasonable 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

<PAGE>
                                      -91-

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 Company referred
to in this Article Ten, the Trustee, subject to the provisions of Article Seven
hereof, and the Holders of the Notes 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, receiver, assignee for the benefit
of creditors, agent or other person making such payment or distribution,
delivered to the Trustee or the Holders of the Notes, 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
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article
Ten.

      SECTION 10.09. Trustee's Relation to Senior Debt.

            The Trustee and any agent of the Company 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 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

<PAGE>
                                      -92-

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 Company 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 Company
or by any act or failure to act, in good faith, by any such holder, or by any
noncompliance by the Company 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 of the Notes and without impairing
or releasing the subordination provided in this Article Ten or the obligations
hereunder of the Holders of the Notes 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 Company and any other Person.

      SECTION 10.11. Noteholders Authorize Trustee To Effectuate Subordination
                     of Notes.

            Each Holder of Notes by its acceptance of them 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 of Notes, the subordination provided in this 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
Company (whether in bankruptcy,

<PAGE>
                                      -93-

insolvency, receivership, reorganization or similar proceedings or upon an
assignment for the benefit of creditors or otherwise) tending towards
liquidation of the business and assets of the Company, the filing of a claim for
the unpaid balance of its Notes 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 (but not the
obligation) to file and are or is hereby authorized to file an appropriate claim
for and on behalf of the Holders of said Notes. 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 Notes 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 or interest
on the Notes 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
pursuant to other sections in this Indenture.

                                 ARTICLE ELEVEN
