                  INDENTURE, dated as of August 1 , 1996, between 

Inter(bullet)Act Systems, Incorporated, a North Carolina corporation (herein 

called the "Company"), and Fleet National Bank, a national banking association,

as Trustee (herein called the "Trustee").


                             RECITALS OF THE COMPANY

                  The Company has duly authorized the creation of an issue of 

14% Senior Discount Notes due 2003 (herein called the "Initial Securities") and
14% Senior Discount Notes due 2003 (the "Exchange Securities" and, together with
the Initial Securities, the "Securities"), of substantially the tenor and amount
hereinafter set forth, and to provide therefor the Company has duly authorized
the execution and delivery of this Indenture.

                  Upon the issuance of the Exchange Securities, if any, or the
effectiveness of the Shelf Registration Statement (as defined herein), this
Indenture will be subject to the provisions of the Trust Indenture Act of 1939,
as amended, that are required to be part of this Indenture and shall, to the
extent applicable, be governed by such provisions.

                  Pursuant to the terms of a Purchase Agreement dated as of July
30, 1996 (the "Purchase Agreement") between the Company and the Initial
Purchasers named therein (the "Initial Purchasers"), the Company has agreed to
issue and sell 142,000 units (the "Units"), each Unit consisting of one $1,000
principal amount of the Securities and one Warrant (collectively, the
"Warrants") entitling the holder thereof to purchase shares of Common Stock, no
par value, of the Company from the Company at an exercise price of $0.01 per
share, subject to adjustment as provided in the Warrant Agreement dated as of
the date hereof (the "Warrant Agreement") between the Company and Fleet National
Bank, as the warrant agent. The Securities and the Warrants will become
separately transferable on the earlier of (i) the commencement of the Exchange
Offer (as defined herein) or the effectiveness of the Shelf Registration
Statement for the Notes and (ii) such date as the Initial Purchasers may, in
their discretion, deem appropriate (the "Separation Date").

                  All things necessary have been done to make the Securities,
when executed by the Company and authenticated and delivered hereunder and duly
issued by the Company, the valid obligations of the Company and to make this
Indenture a valid agreement of the Company, in accordance with their and its
terms.










                                                                               2





                  NOW, THEREFORE, THIS INDENTURE WITNESSETH:

                  For and in consideration of the premises and the purchase of
the Securities by the Holders thereof, it is mutually covenanted and agreed, for
the equal and proportionate benefit of all Holders of the Securities, as
follows:

action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and conclusive in favor of the Trustee and the Company, if made in the
manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner that the Trustee deems sufficient.

                  (c) The principal amount and serial numbers of Securities held
by any Person, and the date of holding the same, shall be proved by the Security
Register.

                  (d) If the Company shall solicit from the Holders of
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, by or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do so.
Such record date shall be the record date specified in or pursuant to such Board
Resolution, which shall be a date not earlier than the date 30 days prior to the
first solicitation of Holders generally in connection therewith and not








                                                                              30








later than the date such solicitation is completed. If such a record date is
fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders
of record at the close of business on such record date shall be deemed to be
Holders for the purposes of determining whether Holders of the requisite
proportion of Outstanding Securities have authorized or agreed or consented to
such request, demand, authorization, direction, notice, consent, waiver or other
Act, and for that purpose the Outstanding Securities shall be computed as of
such record date; PROVIDED that no such authorization, agreement or consent by
the Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than 120 days
after the record date.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

                  SECTION 105.  Notices, Etc., to Trustee and Company.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: Corporate Trust Administration, or

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless otherwise herein
         expressly provided) if in writing and mailed, first-class postage
         prepaid, to the Company addressed to it at the address of its principal
         office specified in the heading of this Indenture, or at any other
         address previously furnished in writing to the Trustee by the Company.









                                                                              31








                  SECTION 106.  Notice to Holders; Waiver.

                  Where this Indenture provides for notice of any event to
Holders by the Company or the Trustee, such notice shall be sufficiently given
(unless otherwise herein expressly provided) if in writing and mailed,
first-class postage prepaid, to each Holder affected by such event, at his
address as it appears in the Security Register, not later than the latest date,
and not earlier than the earliest date, prescribed for the giving of such
notice. In any case where notice to Holders is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders. Any notice mailed to a Holder in the manner herein prescribed
shall be conclusively deemed to have been received by such Holder, whether or
not such Holder actually receives such notice. Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

                  In case by reason of the suspension of or irregularities in
regular mail service or by reason of any other cause, it shall be impracticable
to mail notice of any event to Holders when such notice is required to be given
pursuant to any provision of this Indenture, then any manner of giving such
notice as shall be satisfactory to the Trustee shall be deemed to be a
sufficient giving of such notice for every purpose hereunder.

                  SECTION 107.  Effect of Headings and Table of Contents.

                  The Article and Section headings herein and the Table of
Contents are for convenience only and shall not affect the construction hereof.

                  SECTION 108.  Successors and Assigns.

                  All covenants and agreements in this Indenture by the Company
shall bind its successors and assigns, whether so expressed or not.

                  SECTION 109.  Separability Clause.

                  In case any provision in this Indenture or in the Securities
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.








                                                                              32







                  SECTION 110.  Benefits of Indenture.

                  Nothing in this Indenture or in the Securities, express or
implied, shall give to any Person, other than the parties hereto, any Paying
Agent, any Securities Registrar and their successors hereunder and the Holders,
any benefit or any legal or equitable right, remedy or claim under this
Indenture.

                  SECTION 111.  Governing Law.

                  This Indenture and the Securities shall be governed by and
construed in accordance with the law of the State of New York. Upon the issuance
of the Exchange Securities or the effectiveness of the Shelf Registration
Statement, this Indenture shall be subject to the provisions of the Trust
Indenture Act that are required to be part of this Indenture and shall, to the
extent applicable, be governed by such provisions; and, if and to the extent
that any provision of this Indenture limits, qualifies or conflicts with another
provision included in this Indenture which is required to be included in this
Indenture by any of Sections 310 to 318, inclusive, of the Trust Indenture Act,
such required provision shall control.

                  SECTION 112. Legal Holidays.

                  In any case where any Interest Payment Date, Redemption Date,
or Maturity Date of any Security shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of principal (or premium, if any) or interest need not be made on such
date, but may be made on the next succeeding Business Day with the same force
and effect as if made on the Interest Payment Date, Redemption Date, or at the
Stated Maturity or Maturity; PROVIDED that no interest shall accrue for the
period from and after such Interest Payment Date, Redemption Date or Maturity
Date, as the case may be.



                                   ARTICLE TWO

                                 SECURITY FORMS

                  The definitive Securities shall be typed, printed,
lithographed or engraved or produced by any combination of these methods or may
be produced in any other manner permitted by the rules of any securities
exchange on which the








                                                                              33

Securities, as evidenced by their execution of such Securities.

                  The Securities and the Trustee's certificate of authentication
shall be substantially in the form annexed hereto as Exhibit A. The Securities
may have such appropriate insertions, omissions, substitutions and other
variations as are required or permitted by this Indenture and may have such
letters, notations, numbers or other marks of identification and such legends or
endorsements placed thereon as the Company may deem appropriate (and as are not
prohibited by the terms of this Indenture) or as may be required or appropriate
to comply with any law or with any rules made pursuant thereto or with any rules
of any securities exchange on which such Securities may be listed, or to conform
to general usage, or as may, consistently herewith, be determined by the
officers executing such Securities, as evidenced by their execution of such
Securities. Any portion of the text of any Security may be set forth on the
reverse thereof, with an appropriate reference thereto on the face of the
Security. The Company shall approve the form of the Securities and any notation,
legend or endorsement on the Securities. Each Security shall be dated the date
of its authentication.

                  The terms and provisions contained in the form of the
Securities annexed hereto as Exhibit A shall constitute, and are hereby

hereinafter provided.

                  Initial Securities offered and sold in offshore transactions
in reliance on Regulation S shall be issued in the form of a single global

no longer required pursuant to Section 202, in permanent global form, in each
case in registered form substantially in the form set forth in Exhibit A (the
"Offshore Global Security") deposited with the Trustee, as custodian for the
Depositary, duly executed by the Company and authenticated by the Trustee as

referred to as the "Global Securities."

                  SECTION 202.  Restrictive Legends.

                  Unless and until (i) an Initial Security is sold under an
effective Registration Statement or (ii) an Initial Security is exchanged for an
Exchange Security in connection with an effective Registration Statement, in
each case pursuant to the Registration Rights Agreement, (A) each U.S. Global
Security and each U.S. Physical Security shall bear the following legend set
forth below (the "Private Placement Legend") on the face thereof and (B) the
Offshore Physical Securities and the Offshore Global Security shall bear the

         OTHERWISE DISPOSED OF IN ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH
         TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION. THE HOLDER

         OTHERWISE








                                                                              35

         WHOLE, BUT NOT IN PART, TO DTC OR NOMINEES OF DTC OR TO A SUCCESSOR OF

                                 THE SECURITIES

                  SECTION 301.  Title and Terms.

                  The aggregate principal amount at final maturity of Securities
which may be authenticated and delivered under this Indenture is limited to
$142,000,000 except for Securities authenticated and delivered upon registration
of transfer of, or in exchange for, or in lieu of, other Securities pursuant to
Section 304, 305, 308, 906, 1016, 1017 or 1108.

                  The Initial Securities shall be known and designated as the
"14% Senior Discount Notes due 2003" and the Exchange Securities shall be known
and designated as the "14% Senior Discount Notes due 2003," in each case of the
Company. Their Stated Maturity shall be August 1, 2003 and, except as may be
otherwise provided for in the Securities, they shall bear interest at the rate
of 14% per annum from August 1, 1999, or from the most recent Interest Payment
Date to which interest has been paid or duly provided for, payable on February
1, 2000 and semi-annually thereafter on August 1 and February 1 in each year and
at said Stated Maturity, until the principal thereof is paid or duly provided
for.

                  The principal of (and premium, if any) and interest on the
Securities shall be payable at the office or agency of the Company maintained
for such purpose in The City of New York, or at such other office or agency of
the Company as may be maintained for such purpose; PROVIDED, HOWEVER, that, at
the option of the Company, interest may be paid by check mailed to addresses of
the Persons entitled thereto as such addresses shall appear on the Security
Register.

                  The Securities shall be redeemable as provided in Article
Eleven.

                  SECTION 302.  Denominations.

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








                                                                              38






                  SECTION 303.  Execution, Authentication, Delivery and Dating.

                  The Securities shall be executed on behalf of the Company by
its Chairman, its President or a Vice President, under its corporate seal
reproduced thereon. The signature of any of these officers on the Securities may
be manual or facsimile signatures of the present or any future such authorized
officer and may be imprinted or otherwise reproduced on the Securities. The seal
of the Company, if any, may be in the form of a facsimile thereof and may be
impressed, affixed, imprinted or otherwise reproduced on the Securities.

                  Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities. In addition, any
Security may be signed on behalf of the Company by such Persons as, at the
actual date of the execution of such Security, shall be the proper officers of
the Company, although at the date of such Security or of the execution of this
Indenture any such Person was not such officer.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities, and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities.

                  Each Security shall be dated the date of its authentication.

                  No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for
herein duly executed by the Trustee by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.

                  In case the Company, pursuant to Article Eight, shall be
consolidated or merged with or into any other Person or shall convey, transfer,
lease or otherwise dispose of its properties and assets substantially as an
entirety to any Person, and the successor Person resulting from such
consolidation, or surviving such merger, or into which the Company shall have
been merged, or the Person which shall have received a conveyance, transfer,
lease or other disposition as aforesaid, shall have executed an








                                                                              39






indenture supplemental hereto with the Trustee pursuant to Article Eight, any of
the Securities authenticated or delivered prior to such consolidation, merger,
conveyance, transfer, lease or other disposition may, from time to time, at the
request of the successor Person, be exchanged for other Securities executed in
the name of the successor Person with such changes in phraseology and form as
may be appropriate, but otherwise in substance of like tenor as the Securities
surrendered for such exchange and of like principal amount at maturity; and the
Trustee, upon Company Request of the successor Person, shall authenticate and
deliver Securities as specified in such Request for the purpose of such
exchange. If Securities shall at any time be authenticated and delivered in the
name of a successor Person pursuant to this Section in exchange or substitution
for or upon registration of transfer of any Securities, such successor Person,
at the option of the Holders but without expense to them, shall provide for the
exchange of all Securities at the time Outstanding for Securities authenticated
and delivered in such name.

                  SECTION 304.  Temporary Securities.

                  Pending the preparation of definitive Securities, the Company
may execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as conclusively evidenced
by their execution of such Securities.

                  If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for such purpose
pursuant to Section 1002, without charge to the Holder (except as provided in
Section 305). Upon surrender for cancellation of any one or more temporary
Securities, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount at maturity of definitive
Securities of authorized denominations. Until so exchanged, the temporary
Securities shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities.









                                                                              40






                  SECTION 305. Registration, Registration of Transfer and
Exchange.

                  The Company shall keep or cause to be kept at the Corporate
Trust Office of the Trustee a register (the register maintained in such office
and in any other office or agency designated pursuant to Section 1002 being
herein sometimes referred to as the "Security Register") in which, subject to
such reasonable regulations as it may prescribe, the Company shall provide for
the registration of Securities and of transfers and exchanges of Securities. The
Security Register shall be in written form or any other form capable of being
converted into written form within a reasonable time. At all reasonable times,
the Security Register shall be open to inspection by the Trustee. The Trustee is
hereby initially appointed as security registrar (the "Security Registrar") for
the purpose of registering Securities and transfers and exchanges of Securities
as herein provided.

                  Upon surrender for registration of transfer of any Security at
the Corporate Trust Office of the Trustee or the office or agency of the Company
designated pursuant to Section 1002, the Company shall execute, and the Trustee
shall authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Securities of any authorized denomination or
denominations of a like aggregate principal amount at maturity.

                  At the option of the Holder, Securities may be exchanged for
other Securities of any authorized denomination and of a like aggregate
principal amount at maturity, upon surrender of the Securities to be exchanged
at the Corporate Trust Office of the Trustee or such office or agency. Whenever
any Securities are so surrendered for exchange, the Company shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder
making the exchange is entitled to receive; PROVIDED that no exchange of Initial
Securities for Exchange Securities shall occur until an Exchange Offer
Registration Statement shall have been declared effective by the Commission and
that the Initial Securities to be exchanged for the Exchange Securities shall be
cancelled by the Trustee.

                  All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

                  Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company) be duly endorsed,
or be accompanied by a written instrument of transfer, in form satisfactory to
the Company








                                                                              41







and the Security Registrar, duly executed by the Holder thereof or his attorney
duly authorized in writing.

                  No service charge shall be payable by the Holders for any
registration of transfer or exchange or redemption of Securities, but the
Company may require payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection with any registration of
transfer or exchange of Securities, other than transfer taxes and similar
charges with respect to exchanges pursuant to Section 304, 906, 1016, 1017 or
1108 not involving any transfer.

                  The Company shall not be required (i) to issue or register the
transfer of or exchange any Security during a period beginning at the opening of
business 15 days before the selection of Securities to be redeemed under Section
1104 and ending at the close of business on the day of mailing of the relevant
notice of redemption, or (ii) to register the transfer of or exchange any
Security so selected for redemption in whole or in part, except the unredeemed
portion of any Security being redeemed in part.

                  Prior to the time that the Company has notified the Security
Registrar that the Separation Date has occurred, the Security Registrar shall
notify the Trustee and the warrant agent under the Warrant Agreement of any
transfer of any Security and the identify of any transferees thereof. Prior to
the Separation Date, no transfer of any Security shall be permitted without
transfer of the Warrant with which such Security comprises a Unit. The Company
shall give the Trustee immediate notice of any Separation Date.

                  SECTION 306. Book-Entry Provisions for Global Securities. (a)
The U.S. Global Security and Offshore Global Security initially shall (i) be
registered in the name of the Depositary for such Global Securities or the
nominee of such Depositary, (ii) be delivered to the Trustee as custodian for
such Depositary and (iii) bear legends as set forth in Section 202.

                  Members of, or participants in, the Depositary ("Agent
Members") shall have no rights under this Indenture with respect to any Global
Security held on their behalf by the Depositary, or the Trustee as its
custodian, or under any Global Security, and the Depositary may be treated by
the Company, the Trustee and any agent of the Company or the Trustee as the
absolute owner of such Global Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Company, the
Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depositary
or impair, as between the Depositary and its Agent Members, the








                                                                              42







operation of customary practices governing the exercise of the rights of a
beneficial ownership of any Security.

                  (b) Transfers of a Global Security shall be limited to
transfers of such Global Security in whole, but not in part, to the Depositary,
its successors or their respective nominees. Interests of beneficial owners in a
Global Security may be transferred in accordance with the applicable rules and
procedures of the Depositary and the provisions of Section 307. In addition,
U.S. Physical Securities or Offshore Physical Securities shall be transferred to
all beneficial owners in exchange for their beneficial interests in the U.S.
Global Security or the Offshore Global Security, respectively, if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for the U.S. Global Security or the Offshore Global Security, as the
case may be, or the Depositary ceases to be a "Clearing Agency" registered under
the Exchange Act and a successor depositary is not appointed by the Company
within 90 days or (ii) an Event of Default has occurred and Holders of more than
25% in aggregate principal amount of the Securities at the time outstanding
represented by the Global Securities advise the Trustee through the Depositary
in writing that the continuation of a book-entry system through the Depositary
with respect to the Global Securities is no longer required.

                  (c) Any beneficial interest in one of the Global Securities
that is transferred to a person who takes delivery in the form of an interest in
the other Global Security will, upon transfer, cease to be an interest in such
Global Security and become an interest in the other Global Security and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Security for as long as it remains such an interest.

                  (d) In connection with any transfer pursuant to paragraph (b)
of this Section of a portion of the beneficial interests in the U.S. Global
Security to beneficial owners who are required to hold U.S. Physical Securities,
the Registrar shall reflect on its books and records the date and a decrease in
the principal amount at maturity of the U.S. Global Security in an amount equal
to the principal amount at maturity of the beneficial interest in the U.S.
Global Security to be transferred, and the Company shall execute, and the
Trustee shall authenticate and deliver, one or more U.S. Physical Securities of
like tenor and amount.

                  (e) In connection with the transfer of the entire U.S. Global
Security or Offshore Global Security to beneficial owners pursuant to paragraph
(b) of this Section, the U.S. Global Security or Offshore Global Security, as
the case may be, shall be deemed to be surrendered to the Trustee for
cancellation, and the Company








                                                                              43






shall execute, and the Trustee shall authenticate and deliver, to each
beneficial owner identified by the Depositary in exchange for its beneficial
interest in the U.S. Global Security or Offshore Global Security, as the case
may be, an equal aggregate principal amount at maturity of U.S. Physical
Securities or Offshore Physical Securities, as the case may be, of authorized
denominations.

                  (f) Any U.S. Physical Security delivered in exchange for an
interest in the U.S. Global Security pursuant to paragraph (b) or (d) of this
Section shall, except as otherwise provided by paragraph (a)(i)(x) or paragraph
(e) of Section 307, bear the legend regarding transfer restrictions applicable
to the U.S. Physical Security set forth in Section 202.

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

                  (h) Beneficial owners of interests in a Global Security may
receive Physical Securities (which shall bear the Private Placement Legend if
required by Section 202) in accordance with the procedures of the Depositary. In
connection with the execution, authentication and delivery of such Physical
Securities, the Registrar shall reflect on its books and records a decrease in
the principal amount at maturity of the relevant Global Security equal to the
principal amount at maturity of such Physical Securities and the Company shall
execute and the Trustee shall authenticate and deliver one or more Physical
Securities having an equal aggregate principal amount at maturity.

                  SECTION 307. Special Transfer Provisions. Unless and until (i)
an Initial Security is sold under an effective Registration Statement (as
certified to the Trustee by the Company), or (ii) an Initial Security is
exchanged for an Exchange Security in connection with an effective Registration
Statement, in each case pursuant to the Registration Rights Agreement, the
following provisions shall apply:

                  (a) Transfers to Non-QIB Institutional Accredited Investors.
         The following provisions shall apply with respect to the registration
         of any proposed transfer of an Initial Security to any Institutional
         Accredited Investor which is not a QIB (excluding Non-U.S. Persons):

                           (i) The Registrar shall register the transfer of any
                  Security, whether or not such Security bears the Private
                  Placement Legend, if (x) the requested transfer is at least
                  three years after the original issue








                                                                              44






                  date of the Initial Securities or (y) the proposed transferee
                  has delivered to the Registrar a certificate substantially in
                  the form of Exhibit C hereto.

                           (ii) If the proposed transferor is an Agent Member
                  holding a beneficial interest in the U.S. Global Security,
                  upon receipt by the Registrar of (x) the documents, if any,
                  required by paragraph (i), and (y) instructions given in
                  accordance with the Depositary's and the Registrar's
                  procedures therefor, the Registrar shall reflect on its books
                  and records the date and a decrease in the principal amount of
                  the U.S. Global Security in an amount equal to the principal
                  amount of the beneficial interest in the U.S. Global Security
                  to be transferred, and the Company shall execute, and the
                  Trustee shall authenticate and deliver, one or more U.S.
                  Physical Securities of like tenor and amount.

                  (b) Transfers to QIBs. The following provisions shall apply
         with respect to the registration of any proposed transfer of a U.S.
         Physical Security or an interest in the U.S. Global Security to a QIB
         (excluding Non-U.S.
         Persons):

                           (i) If the Security to be transferred consists of (x)
                  U.S. Physical Securities, the Security Registrar shall
                  register the transfer if such transfer is being made by a
                  proposed transferor who has checked the box provided for on
                  the form of Initial Security stating, or has otherwise advised

                  144A to a transferee who has signed the certification provided
                  for on the form of Initial Security stating, or has otherwise
                  advised the Company and the Security Registrar in writing,
                  that it is purchasing the Initial Security for its own account
                  or an account with respect to which it exercises sole
                  investment discretion and that it and any such account is a
                  QIB within the meaning of Rule 144A, and is aware that the
                  sale to it is being made in reliance on Rule 144A and
                  acknowledges that it has received such information regarding
                  the Company as it has requested pursuant to Rule 144A or has
                  determined not to request such information and that it is
                  aware that the transferor is relying upon its foregoing
                  representations in order to claim the exemption from

                  Depositary.









                                                                              45






                  (ii) If the proposed transferee is an Agent Member, and the
         Security to be transferred consists of U.S. Physical Securities, upon
         receipt by the Security Registrar of the documents referred to in
         clause (i) and instructions given in accordance with the Depositary's
         and the Security Registrar's procedures, the Security Registrar shall
         reflect on its books and records the date and an increase in the
         principal amount at maturity of the U.S. Global Security in an amount
         equal to the principal amount at maturity of the U.S. Physical
         Securities to be transferred, and the Trustee shall cancel the Physical
         Securities so transferred.

                  (c) Transfers of Interests in the Offshore Global Security or
Offshore Physical Securities to U.S. Persons. The following provisions shall
apply with respect to any transfer of interests in the Offshore Global Security
or Offshore Physical Securities to U.S. Persons:

                  (i) prior to the removal of the Private Placement Legend from
         the Offshore Global Security or Offshore Physical Securities pursuant
         to Section 202, the Security Registrar shall refuse to register such
         transfer; and

                  (ii) after such removal, the Security Registrar shall register
         the transfer of any such Security without requiring any additional
         certification.

                  (d) Transfers to Non-U.S. Persons at Any Time. The following
provisions shall apply with respect to any transfer of an Initial Security to a
Non-U.S.
Person:

                  (i) The Security Registrar shall register any proposed
         transfer to any Non-U.S. Person if the Security to be transferred is a
         U.S. Physical Security or an interest in the U.S. Global Security only
         upon receipt of a certificate substantially in the form of Exhibit D
         from the proposed transferor.

                  (ii) (x) If the proposed transferee is an Agent Member holding
         a beneficial interest in the U.S. Global Security, upon receipt by the
         Security Registrar of (1) the documents required by paragraph (i) and
         (2) instructions in accordance with the Depositary's and the Security
         Registrar's procedures, the Security Registrar shall reflect on its
         books and records the date and a decrease in the principal amount at
         maturity of the U.S. Global Security in an amount equal to the
         principal amount at maturity of the beneficial interest in the U.S.
         Global Security to be transferred, and (y) if the proposed transferee
         is an Agent Member, upon receipt by the Security Registrar of
         instructions given in accordance with the Depositary's and the Security
         Registrar's procedures,








                                                                              46







         the Security Registrar shall reflect on its books and records the date
         and an increase in the principal amount at maturity of the Offshore
         Global Security in an amount equal to the principal amount at maturity
         of the U.S. Physical Security or the U.S. Global Security, as the case
         may be, to be transferred, and the Trustee shall cancel the Physical
         Security, if any, so transferred or decrease the amount of the U.S.
         Global Security.

                  (e) Private Placement Legend. Upon the transfer, exchange or
replacement of Securities not bearing the Private Placement Legend, the Security
Registrar shall deliver Securities that do not bear the Private Placement
Legend. Upon the transfer, exchange or replacement of Securities bearing the
Private Placement Legend, the Security Registrar shall deliver only Securities
that bear the Private Placement Legend unless either (i) the Private Placement
Legend is no longer required by Section 202 or (ii) there is delivered to the
Security Registrar an Opinion of Counsel reasonably satisfactory to the Company
and the Trustee to the effect that neither such Legend nor the related
restrictions on transfer are required in order to maintain compliance with the
provisions of the Securities Act.

                  (f) General. By its acceptance of any Security bearing the
Private Placement Legend, each Holder of, or beneficial owner of an interest in,
such Security acknowledges the restrictions on transfer of such Security set
forth in this Indenture and in the Private Placement Legend and agrees that it
will transfer such Security only as provided in this Indenture. The Security
Registrar shall not register a transfer of any Security unless such transfer
complies with the requirements of this Section 307. In connection with any
transfer of Securities to an Institutional Accredited Investor, each such Holder
or beneficial owner agrees by its acceptance of the Securities to furnish the
Security Registrar or the Company such certifications, legal opinions or other
information as such Person may reasonably require to confirm that such transfer
is being made pursuant to an exemption from, or a transaction not subject to,
the registration requirements of the Securities Act; PROVIDED that the Security
Registrar shall not be required to determine (but may rely on a determination
made by the Company with respect to) the sufficiency of any such certifications,
legal opinions or other information. The Security Registrar's only obligation to
enforce the transfer restrictions of this Indenture shall be to require the
certifications and opinions specifically required by this Section 307 as a
condition to transfer.

                  Every replacement Security is an additional obligation of the
Company and shall be entitled to the benefits of this Indenture.









                                                                              47






                  SECTION 308.  Mutilated, Destroyed, Lost and Stolen
Securities.

                  If (i) any mutilated Security is surrendered to the Trustee,
or (ii) the Company and the Trustee receive evidence to their satisfaction of
the destruction, loss or theft of any Security, and there is delivered to the
Company and the Trustee such security or indemnity as may be required by them to
save each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon Company Order the Trustee shall authenticate and
deliver, in exchange for any such mutilated Security or in lieu of any such
destroyed, lost or stolen Security, a new Security of like tenor, form, terms
and principal amount, bearing a number not contemporaneously Outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay or authorize the payment of such
Security.

                  Upon the issuance of any new Security under this Section, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new Security issued pursuant to this Section in lieu of
any mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

                  All Securities shall be held and owned upon the express
condition that the foregoing provisions of this Section are exclusive with
respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities and shall preclude any and all other rights or remedies,
notwithstanding any law or statute existing or hereinafter enacted to the
contrary with respect to the replacement or payment of negotiable instruments or
other securities without their surrender.

                  SECTION 309.  Payment of Interest; Interest Rights Preserved.

                  Interest on any Security 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 such Security (or one or more Predecessor Securities) is
registered at the close








                                                                              48




of business on the Regular Record Date for such interest at the office or agency
of the Company maintained for such purpose pursuant to Section 1002; PROVIDED,
HOWEVER, that each installment of interest may at the Company's option be paid
by (i) mailing a check for such interest, payable to or upon the written order
of the Person entitled thereto pursuant to Section 310, to the address of such
Person as it appears in the Security Register at the close of business on the
Regular Record Date for such interest payment or (ii) transfer to an account
located in the United States maintained by the payee the details of which
account are notified to the Security Registrar prior to the close of business on
the Record Date for such interest payment.

                  Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the Holder on the Regular Record Date by virtue
of having been such Holder, and such defaulted interest and (to the extent
lawful) interest on such defaulted interest at the rate borne by the Securities
(such defaulted interest and interest thereon herein collectively called
"Defaulted Interest") may be paid by the Company, at its election in each case,
as provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities (or their
         respective Predecessor Securities) are registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed to be paid on each Security and the date of the proposed
         payment, and at the same time the Company shall deposit with the
         Trustee an amount of money equal to the aggregate amount proposed to be
         paid in respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         clause provided. Thereupon the Trustee shall fix a Special Record Date
         for the payment of such Defaulted Interest which shall be not more than
         15 days and not less than 10 days prior to the date of the proposed
         payment and not less than 10 days after the receipt by the Trustee of
         the notice of the proposed payment. The Trustee shall promptly notify
         the Company of such Special Record Date, and in the name and at the
         expense of the Company, shall cause notice of the proposed payment of
         such Defaulted Interest and the Special Record Date therefor to be
         given in the manner provided for in Section 106, not less than 10 days
         prior to such Special Record Date. Notice of the proposed payment of
         such Defaulted Interest and the Special Record Date therefor having
         been so given, such Defaulted Interest shall be paid to the Persons in
         whose names the Securities








                                                                              49







         (or their respective Predecessor Securities) are registered at the
         close of business on such Special Record Date and shall no longer be
         payable pursuant to the following clause (2).

                  (2) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Securities may be listed, and upon
         such notice as may be required by such exchange, if, after notice given
         by the Company to the Trustee of the proposed payment pursuant to this
         clause, such manner of payment shall be deemed practicable by the
         Trustee.

                  Subject to the foregoing provisions of this Section, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

                  SECTION 310.  Persons Deemed Owners.

                  Prior to the due presentment of a Security 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 Security is registered as the owner of
such Security for the purpose of receiving payment of principal of (and premium,
if any) and (subject to Sections 305 and 309) interest on such Security and for
all other purposes whatsoever, whether or not such Security be overdue, and none
of the Company, the Trustee or any agent of the Company or the Trustee shall be
affected by notice to the contrary.

                  SECTION 311.  Cancellation.

                  All Securities surrendered for payment, redemption,
registration of transfer or exchange shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it. The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly cancelled by the Trustee. If
the Company shall so acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for cancellation. No Securities shall be authenticated in lieu of or in








                                                                              50




exchange for any Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture. All cancelled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with its customary
procedures and certification of their disposal delivered to the Company unless
by Company Order the Company shall direct that cancelled Securities be returned
to it.

                  SECTION 312.  Computation of Interest.

                  Interest on the Securities shall be computed on the basis of a
360-day year of 12 30-day months.

                  SECTION 313.  Wire Transfers.

                  Notwithstanding any other provision to the contrary in this
Indenture, the Company may make any payment of monies required to be deposited
with the Trustee on account of principal of, or premium, if any, or interest on,
the Securities (whether pursuant to optional or mandatory redemption payments,
interest payments or otherwise) by wire transfer in immediately available funds
to an account designated by the Trustee on or before 10:00 a.m. (New York City
time) the date such moneys are to be paid to the Holders of the Securities in
accordance with the terms hereof.

                           SATISFACTION AND DISCHARGE

                  SECTION 401. Satisfaction and Discharge of Indenture.

                  This Indenture shall upon Company Request cease to be of
further effect (except as to surviving rights and obligations of the Trustee
expressly provided for in this Indenture and the surviving rights of
registration of transfer or exchange of Securities expressly provided for herein
or pursuant hereto) and the Trustee, at the direction and expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture when

                  (1)  either

                           (a) all Securities theretofore authenticated and
         delivered (other than (i) Securities which have been destroyed, lost or
         stolen and which have been replaced or paid as provided in Section 308
         and (ii) Securities for whose payment money has theretofore been
         deposited in trust with the Trustee or any








                                                                              51








         Paying Agent or segregated and held in trust by the Company and
         thereafter repaid to the Company or discharged from such trust, as
         provided in Section 1003) have been delivered to the Trustee for
         cancellation; or

                  (b) all such Securities not theretofore delivered to the
         Trustee for cancellation

                                    (i)  have become due and payable, or

                                    (ii)  will become due and payable at their
                  Stated Maturity within one year, or

                  one year under arrangements satisfactory to the Trustee for
                  the giving of notice of redemption by the Trustee in the name,
                  and at the expense, of the Company,

         and the Company, in the case of (i), (ii) or (iii) above, has
         irrevocably deposited or caused to be deposited with the Trustee as
         trust funds in trust for such purpose an amount sufficient to pay and
         discharge the entire indebtedness on such Securities not theretofore
         delivered to the Trustee for cancellation, for principal of (and
         premium, if any) and interest to the date of such deposit (in the case
         of Securities which have become due and payable) or to the Stated
         Maturity or Redemption Date, as the case may be;

                  (2)  the Company has paid or caused to be paid all other sums
         payable hereunder by the Company; and

                  (3) the Company has delivered to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         precedent herein provided for relating to the satisfaction and
         discharge of this Indenture have been complied with.

                  Notwithstanding the satisfaction and discharge of this
Indenture, the obligations of the Company to the Trustee under Section 606 and,
if money shall have been deposited with the Trustee pursuant to subclause (B) of
clause (1) of this Section, the obligations of the Trustee under Section 402 and
the last paragraph of Section 1003 shall survive.









                                                                              52





                  SECTION 402. Application of Trust Money.

                  Subject to the provisions of the last paragraph of Section
1003, all money deposited with the Trustee pursuant to Section 401 shall be held
in trust and applied by it, in accordance with the provisions of the Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee; but such money need not be segregated from other funds except to the
extent required by law. So long as no Event of Default shall have occurred and
be continuing, all interest allowed on any such moneys shall be paid from time
to time to the Company upon a Company Order.

         Company by the Trustee or to the Company








                                                                              53

         making by it of an assignment for the benefit of creditors, or the
         admission by it in writing of its inability to pay its debts generally

                           SECTION 502. Acceleration of Maturity; Rescission and
         Annulment.

                  If an Event of Default (other than an Event of Default
specified in Section 501(8) or (9)) occurs and is continuing, then and in every
such case the Trustee or the Holders of not less than 25% in principal amount of
the Securities Outstanding may declare the principal of all the Securities to be
due and payable immediately in an amount equal to (i) the Accreted Value of the
Securities as of the date on which the Securities first become due and payable,
if such date occurs prior to August 1, 1999, or (ii) the Accreted Value of the
Securities as of the date on which the Securities first become due and payable
plus accrued and unpaid interest, if any, to such date, if such date occurs on
or after August 1, 1999, by a notice in writing to the Company (and to the
Trustee if given by Holders), and upon any such declaration such principal shall
become immediately due and payable. If an Event of Default specified in Section
501(8) or (9) occurs and is continuing, then the principal of all the Securities
shall IPSO FACTO become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder in an amount
equal to (i) the Accreted Value of the Securities as of the date on which the
Securities first become due and payable, if such date occurs prior to August 1,
1999, or (ii) the Accreted Value of the Securities as of the date on which the
Securities first become due and payable plus accrued and unpaid interest, if
any, to such date, if such date occurs on or after August 1, 1999.

                  At any time after a declaration of acceleration has been made
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter provided in this Article, the Holders of a
majority in principal amount of the Securities Outstanding, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its
consequences if

                  (1)  the Company has paid or deposited with the Trustee a sum
         sufficient to pay,

                           (A)  all overdue interest on all Outstanding
                  Securities,

                           (B) all unpaid principal of and premium, if any, on
                  any Outstanding Securities which has become due otherwise than
                  by such declaration of acceleration, and interest on such
                  unpaid principal at the rate borne by the Securities,








                                                                              55




                           (C) to the extent that payment of such interest is
                  lawful, interest on overdue interest and overdue principal at
                  the rate borne by the Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel; and

                  (2) all Events of Default, other than the nonpayment of
         amounts of principal of or premium, if any, on or interest on
         Securities which have become due solely by such declaration of
         acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

                  SECTION 503. Collection of Indebtedness and Suits for
Enforcement by Trustee.

         The Company covenants that if

                  (a) default is made in the payment of any installment of
         interest on any Security when such interest becomes due and payable and
         such default continues for a period of 30 days, or

                  (b) default is made in the payment of the principal of or
         premium, if any, on any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee for the benefit
of the Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and interest on any
overdue principal (and premium, if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installment of interest,
at the rate borne by the Securities, and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel.

                  If the Company fails to pay such amounts forthwith upon such
demand, the Trustee, in its own name as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such








                                                                              56







proceeding to judgment or final decree and may enforce the same against the
Company or any other obligor upon the Securities and collect the moneys adjudged
or decreed to be payable in the manner provided by law out of the property of
the Company or any other obligor upon the Securities, wherever situated.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

                  SECTION 504.  Trustee May File Proofs of Claim.

                  In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal, premium, if any, or interest)
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

                  (i) to file and prove a claim for the whole amount of
         principal (and premium, if any) and interest owing and unpaid in
         respect of the Securities and to file such other papers or documents as
         may be necessary or advisable in order to have the claims of the
         Trustee (including any claim for the reasonable compensation, expenses,
         disbursements and advances of the Trustee, its agents and counsel) and
         of the Holders allowed in such judicial proceeding, and

                  (ii) collect and receive any moneys or other property payable
         or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
similar official in any such judicial proceeding is hereby authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 606.








                                                                              57









                  Nothing herein contained shall be deemed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof, or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

                  SECTION 505.  Trustee May Enforce Claims Without Possession of
Securities.

                  All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name and as trustee of an express trust, and any recovery of judgment
shall, after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

                  SECTION 506.  Application of Money Collected.

                  Any money collected by the Trustee pursuant to this Article
shall be applied in the following order, at the date or dates fixed by the
Trustee and, in case of the distribution of such money on account of principal
(or premium, if any) or interest, upon presentation of the Securities and the
notation thereon of the payment, if only partially paid, and upon surrender
thereof if fully paid:

                  FIRST:  To the payment of all amounts due the Trustee under
         Section 606;

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of (and premium, if any) and interest on the Securities in
         respect of which or for the benefit of which such money has been
         collected, ratably, without preference or priority of any kind,
         according to the amounts due and payable on such Securities for
         principal (and premium, if any) and interest, respectively; and

                  THIRD: The balance, if any, to the Company, its successors or
         assigns, or to any other Person or Persons lawfully entitled thereto.









                                                                              58








                  SECTION 507.  Limitation on Suits.

                  No Holder of any Securities shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for
the appointment of a receiver or trustee, or for any other remedy hereunder,
unless

                  (1)  such Holder has previously given written notice to the
         Trustee of a continuing Event of Default;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities shall have made written request to the
         Trustee to institute proceedings in respect of such Event of Default in
         its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such action
         or proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority or more in principal amount of the Outstanding Securities;

it being understood and intended, and being expressly covenanted by the Holder
of every Security with every other Holder and the Trustee, that no one or more
Holders shall have any right in any manner whatever by virtue of, or by availing
of, any provision of this Indenture to affect, disturb or prejudice the rights
of any other Holders, or to obtain or to seek to obtain priority or preference
over any other Holders or to enforce any right under this Indenture, except in
the manner herein provided and for the equal and ratable benefit of all the
Holders.

                  SECTION 508.  Unconditional Right of Holders to Receive
Principal, Premium and Interest.

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment, as provided herein (including, if applicable,
Article Thirteen) and in such Security of the principal of (and premium, if any)
and (subject to Section 309) interest on such Security on the respective Stated
Maturities expressed in such Security (or, in







                                                                              59






the case of redemption, on the Redemption Date) and to institute suit for the
enforcement of any such payment on or after such respective dates, and such
rights shall not be impaired without the consent of such Holder.

                  SECTION 509.  Restoration of Rights and Remedies.

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

                  SECTION 510.  Rights and Remedies Cumulative.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 308, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now, or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

                  SECTION 511.  Delay or Omission Not Waiver.

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

                  SECTION 512.  Control by Holders.

                  Subject to the provisions of Section 602(5), the Holders of
not less than a majority in principal amount of the Outstanding Securities shall
have the right to direct the time, method and place of conducting any proceeding
for any remedy








                                                                              60






available to the Trustee, or exercising any trust or power conferred on the
Trustee, PROVIDED that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture,

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction, and

                  (3) the Trustee need not take any action which might involve
         it in personal liability or be unjustly prejudicial to the Holders not
         consenting.

                  SECTION 513. Waiver of Past Defaults.

                  The Holders of not less than a majority in principal amount of
the Outstanding Securities may, on behalf of the Holders of all the Securities,
waive any past Default hereunder and its consequences, except a Default

                  (1) in respect of the payment of the principal of (or premium,
         if any) or interest on any Security, or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security affected.

                  Upon any such waiver, such Default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent
thereon.

                  SECTION 514. Waiver of Stay or Extension Laws.

                  The Company covenants (to the extent that it may lawfully do
so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law
wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage of
any such law and 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.








                                                                              61

                                   THE TRUSTEE

                  SECTION 601.  Notice of Defaults.

                  Within 30 days after the occurrence of any Default hereunder,
the Trustee shall transmit in the manner and to the extent provided in TIA
Section 313(c), notice of such Default hereunder known to the Trustee, unless
such Default shall have been cured or waived; PROVIDED, HOWEVER, that, except in
the case of a Default in the payment of the principal of (or premium, if any) or
interest on any Security, the Trustee shall be protected in withholding such
notice if and so long as a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interest of the Holders; and PROVIDED FURTHER that in the case
of any Default of the character specified in Section 501(4) no such notice to
Holders shall be given until at least 30 days after the occurrence thereof.

                  SECTION 602.  Certain Rights of Trustee.

                  Subject to the provisions of TIA Sections 315(a) through
315(d):

                  (1) the Trustee may rely and shall be protected in acting or
         refraining from acting upon any resolution, certificate, statement,
         instrument, opinion, report, notice, request, direction, consent,
         order, bond, debenture, note, other evidence of indebtedness or other
         paper or document believed by it to be genuine and to have been signed
         or presented by the proper party or parties;

                  (2) any request or direction of the Company mentioned herein

         prescribed) and any resolution of the Board of Directors may be
         sufficiently evidenced by a Board Resolution;

                  (3) whenever in the administration of this Indenture the
         Trustee shall deem it desirable that a matter be proved or established
         prior to taking, suffering or omitting any action hereunder, the
         Trustee (unless other evidence is herein specifically prescribed) may,
         in the absence of bad faith on its part, rely upon an Officers'
         Certificate;









                                                                              62






                  (4) the Trustee may consult with counsel and the written
         advice of such counsel or any Opinion of Counsel shall be full and
         complete authorization and protection in respect of any action taken,
         suffered or omitted by it hereunder in good faith and in reliance
         thereon;

                  (5) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by this Indenture at the request
         or direction of any of the Holders pursuant to this Indenture, unless
         such Holders shall have offered to the Trustee reasonable security or
         indemnity against the costs, expenses and liabilities which might be
         incurred by it in compliance with such request or direction;

                  (6) prior to the occurrence of an Event of Default and after
         the curing of all Events of Default which may have occurred, the
         Trustee shall not be bound to make any investigation into the facts or
         matters stated in any resolution, certificate, statement, instrument,
         opinion, report, notice, request, direction, consent, order, bond,
         debenture, note, other evidence of indebtedness or other paper or
         document, but the Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit,
         and, if the Trustee shall determine to make such further inquiry or
         investigation, it shall be entitled to examine the books, records and
         premises of the Company, personally or by agent or attorney;

                  (7) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through agents or attorneys and the Trustee shall not be responsible
         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder; and

                  (8) the Trustee shall not be liable for any action taken,
         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture.

                  The Trustee shall not be required to 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.









                                                                              63





                  SECTION 603. Trustee Not Responsible for Recitals or Issuance
of Securities.

                  The recitals contained herein and in the Securities, except
for the Trustee's certificates of authentication, shall be taken as the
statements of the Company, and the Trustee assumes no responsibility for their
correctness. The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities, except that the Trustee
represents that it is duly authorized to execute and deliver this Indenture,
authenticate the Securities and perform its obligations hereunder and that the
statements made by it in any Statement of Eligibility on Form T-1 supplied to
the Company will be true and accurate when made, subject to the qualifications
set forth therein. The Trustee shall not be accountable for the use or
application by the Company of Securities or the proceeds thereof.

                  SECTION 604.  May Hold Securities.

                  The Trustee, any Paying Agent, any Security Registrar or any
other agent of the Company or of the Trustee, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to the
Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Paying Agent, Security Registrar or such
other agent.

                  SECTION 605.  Money Held in Trust.

                  Subject to the provisions of Section 506, all moneys received
by the Trustee shall, until used or applied as herein provided, be held in trust
for the purposes for which they were received, but need not be segregated from
other funds except to the extent required by law. The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

                  SECTION 606.  Compensation and Reimbursement.

                  The Company agrees:

                  (1) to pay to the Trustee from time to time such compensation
         as the Company and the Trustee shall agree for all services rendered by
         it hereunder (which compensation shall not be limited by any provision
         of law in regard to the compensation of a trustee of an express trust);









                                                                              64






                  (2) to reimburse the Trustee upon its request for all
         reasonable expenses, disbursements and advances incurred or made by the
         Trustee in accordance with any provision of this Indenture (including
         the reasonable compensation and the expenses and disbursements of its
         agents and counsel), except any such expense, disbursement or advance
         as may be attributable to its negligence or bad faith; and

                  (3) to indemnify the Trustee for, and to hold it harmless
         against, any loss, liability or expense incurred without negligence or
         bad faith on its part, arising out of or in connection with the
         acceptance or administration of this trust, including the costs and
         expenses (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel) of investigating or defending
         itself against any claim or liability in connection with the exercise
         or performance of any of its powers or duties hereunder.

                  The obligations of the Company under this Section to
compensate the Trustee, to pay or reimburse the Trustee for expenses,
disbursements and advances and to indemnify and hold harmless the Trustee shall
constitute additional indebtedness hereunder and shall survive the resignation
or removal of the Trustee and/or the satisfaction and discharge of this
Indenture. As security for the performance of such obligations of the Company,
the Trustee shall have a claim prior to the Securities upon all property and
funds held or collected by the Trustee as such, except funds held in trust for
the payment of principal of (and premium, if any) or interest on particular
Securities.

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 501(8) or (9), the
expenses (including the reasonable charges and expenses of its counsel) of and
the compensation for such services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

                  The provisions of this Section shall survive the termination
of this Indenture.

                  SECTION 607.  Corporate Trustee Required; Eligibility;
Conflicting Interests.

                  There shall be at all times a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and 310(a)(5) and shall
have a combined capital and surplus of at least $50,000,000. If such corporation
publishes reports of condition at least annually, pursuant to law or to the
requirements of








                                                                              65





federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.

                  SECTION 608.  Resignation and Removal; Appointment of
Successor.

                  (a) No resignation or removal of the Trustee and no
appointment of a successor Trustee pursuant to this Article shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 609.

                  (b) The Trustee may resign at any time by giving written
notice thereof to the Company. If the instrument of acceptance by a successor
Trustee required by Section 609 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee.

                  (c) The Trustee may be removed at any time by Act of the
Holders of not less than a majority in principal amount of the Outstanding
Securities, delivered to the Trustee and to the Company.

                  (d)  If at any time:

                  (1) the Trustee shall fail to comply with the provisions of
         TIA Section 310(b) after written request therefor by the Company or by
         any Holder who has been a bona fide Holder of a Security for at least
         six months, or

                  (2) the Trustee shall cease to be eligible under Section 607
         and shall fail to resign after written request therefor by the Company
         or by any Holder who has been a bona fide Holder of a Security for at
         least six months, or

                  (3) the Trustee shall become incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,









                                                                              66






then, in any such case, (i) the Company, by a Board Resolution, may remove the
Trustee, or (ii) Subject to TIA Section 315(e), any Holder who has been a bona
fide Holder of a Security for at least six months may, on behalf of himself and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor Trustee.

                  (e) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Company, by a Board Resolution, shall promptly appoint a
successor Trustee. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities delivered to the Company and the retiring Trustee, the
successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment, become the successor Trustee and supersede the successor Trustee
appointed by the Company. If no successor Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Security for at least
six months may, on behalf of himself and all others similarly situated, and the
Trustee may, petition any court of competent jurisdiction for the appointment of
a successor Trustee.

                  (f) The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee to the
Holders of Securities in the manner provided for in Section 106. Each notice
shall include the name of the successor Trustee and the address of its Corporate
Trust Office.

                  SECTION 609.  Acceptance of Appointment by Successor.

                  Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.








                                                                              67






                  No successor Trustee shall accept its appointment unless at
the time of such acceptance such successor Trustee shall be qualified under the
TIA and eligible under this Article.

                  SECTION 610.  Merger, Conversion, Consolidation or Succession
to Business.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be otherwise qualified and eligible
under this Article, without the execution or filing of any paper or any further
act on the part of any of the parties hereto. In case any Securities shall have
been authenticated, but not delivered, by the Trustee then in office, any
successor by merger, conversion or consolidation to such authenticating trustee
may adopt such authentication and deliver the Securities so authenticated with
the same effect as if such successor Trustee had itself authenticated such
Securities. In case at that time any of the Securities shall not have been
authenticated, any successor Trustee may authenticate such Securities either in
the name of any predecessor hereunder or in the name of the successor Trustee.
In all such cases such certificates shall have the full force and effect which
this Indenture provides for the certificate of authentication of the Trustee
shall have; PROVIDED, HOWEVER, that the right to adopt the certificate of
authentication of any predecessor Trustee or to authenticate Securities in the
name of any predecessor Trustee shall apply only to its successor or successors
by merger, conversion or consolidation.

Securities) equally and ratably with (or prior to) the Indebtedness which upon
such consolidation, merger, conveyance, lease or transfer is to become secured

                  It shall not be necessary for any Act of Holders under this

                  SECTION 903.  Execution of Supplemental Indentures.

                  In executing, or accepting the additional trusts created by,

own rights, duties or immunities under this Indenture or otherwise.








                                                                              73







                  SECTION 904.  Effect of Supplemental Indentures.

                  Upon the execution of any supplemental indenture under this

every Holder of Securities theretofore or thereafter authenticated and delivered
hereunder shall be bound thereby.

                  SECTION 905.  Conformity with Trust Indenture Act.

                  Every supplemental indenture executed pursuant to this Article
shall conform to the requirements of the Trust Indenture Act as then in effect.

                  SECTION 906. Reference in Securities to Supplemental
Indentures.

                  Securities authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities so modified as to conform, in the opinion of the Trustee and the
Company, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities. Failure to make the appropriate notation or to issue a
new Security shall not affect the validity of such amendment.

                  SECTION 907.  Notice of Supplemental Indentures.

                  Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to the provisions of Section 902, the
Company shall give notice thereof to the Holders of each Outstanding Security
affected, in the manner provided for in Section 106, setting forth in general
terms the substance of such supplemental indenture. Failure to provide such

                                                                              74

                  SECTION 1001. Payment of Principal, Premium, if any, and
Interest.

                  The Company covenants and agrees for the benefit of the
Holders that it will duly and punctually pay or cause to be paid the principal
of (and premium, if any) and interest on the Securities in accordance with the
terms of the Securities and this Indenture.

                  SECTION 1002.  Maintenance of Office or Agency.

                  The Company will maintain in The City of New York, an office
or agency where Securities may be presented or surrendered for payment, where
Securities may be surrendered for registration of transfer or exchange and where
notices and demands to or upon the Company in respect of the Securities and this
Indenture may be served. The Trustee's agency at Shawmut Trust Company, 14 Wall
Street, 8th Floor, Window No. 2, New York, New York 10005, shall be such office
or agency of the Company, unless the Company shall designate and maintain some
other office or agency for one or more of such purposes. The Company will give
prompt written notice to the Trustee of any change in the location of any 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 Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

                  The Company may also from time to time designate one or more
other offices or agencies (in or outside of The City of New York) where the
Securities may be presented or surrendered for any or all such purposes and may
from time to time rescind any such designation; PROVIDED, HOWEVER, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain an office or agency in The City of New York for such
purposes. The Company will give prompt written notice to the Trustee of any such
designation or rescission and any change in the location of any such other
office or agency.

                  SECTION 1003.  Money for Security Payments to Be Held in
Trust.

                  If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of (or premium, if any) or
interest on any








                                                                              75







of the Securities, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal of (or premium, if any)
or interest so becoming due until such sums shall be paid to such Persons or
otherwise disposed of as herein provided and will promptly notify the Trustee of
its action or failure so to act.

                  Whenever the Company shall have one or more Paying Agents for
the Securities, it will, on or before 10:00 a.m. on each due date of the
principal of (or premium, if any) or interest on any Securities, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of such
action or any failure so to act.

                  The Company will cause each Paying Agent (other than the
Trustee) to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee, subject to the provisions of this
Section, that such Paying Agent will:

                  (1) hold all sums held by it for the payment of the principal
         of (and premium, if any) or interest on Securities in trust for the
         benefit of the Persons entitled thereto until such sums shall be paid
         to such Persons or otherwise disposed of as herein provided;

                  (2) give the Trustee notice of any default by the Company (or
         any other obligor upon the Securities) in the making of any payment of
         principal (and premium, if any) or interest; and

                  (3) at any time during the continuance of any such default,
         upon the written request of the Trustee, forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

                  Notwithstanding anything in this Section 1003 to the contrary,
the Company may at any time, for the purpose of obtaining the satisfaction and
discharge of this Indenture or for any other purpose pay, or by Company Order
direct any Paying Agent to pay, to the Trustee all sums held in trust by the
Company or such Paying Agent, such sums to be held by the Trustee upon the same
trusts as those upon which such sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such sums.









                                                                              76







                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (or
premium, if any) or interest on any Security and remaining unclaimed for two
years after such principal, premium or interest has become due and payable
shall, subject to applicable escheat laws, be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, The City of
New York, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

                  SECTION 1004.  Corporate Existence.

                  Subject to Article Eight, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect the
corporate existence, rights (charter and statutory) and franchises of the
Company and each Subsidiary; PROVIDED, HOWEVER, that the Company shall not be
required to preserve any such right or franchise if the Board of Directors shall
determine that the preservation thereof is no longer desirable in the conduct of
the business of the Company and its Subsidiaries as a whole and that the loss
thereof is not disadvantageous in any material respect to the Holders.

                  SECTION 1005. Payment of Taxes and Other Claims.

                  The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (a) all material taxes,
assessments and governmental charges levied or imposed upon the Company or any
Subsidiary or upon the income, profits or property of the Company or any
Subsidiary and (b) all lawful claims for labor, materials and supplies, which,
if unpaid, might by law become a material lien upon the property of the Company
or any Subsidiary; 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 the amount, applicability or validity of which is being
contested in good faith by appropriate proceedings.








                                                                              77

                  (a) The Company will deliver to the Trustee, within 120 days
after the end of each fiscal year, a brief certificate from the principal
executive officer, principal financial officer or principal accounting officer
as to his or her knowledge of the Company's compliance with all conditions and
covenants under this Indenture. For purposes of this Section 1008(a), such
compliance shall be determined without regard to any period of grace or
requirement of notice under this Indenture.

                  (b) When any Default has occurred and is continuing under this
Indenture, or if the trustee for or the holder of any other evidence of
Indebtedness of the Company or any Subsidiary gives any notice or takes any
other action with respect to a claimed default (other than with respect to
Indebtedness in the principal amount of less than $5,000,000), the Company shall
deliver to the Trustee by registered or certified mail or by telegram, telex or
facsimile transmission an Officers' Certificate specifying such event, notice or
other action within five Business Days of its occurrence.

                  SECTION 1009. Provision of Reports and Financial Statements.

                  (a) The Company shall file with the Trustee and provide the
Holders of Securities, within 15 days after it files them with the Commission,

other reports (or copies of such portions of any of the foregoing as the
Commission may by rules and regulations prescribe) which the Company is required
to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act.

                  (b) Notwithstanding that the Company may not be subject to the

distributions from the calculation of Cumulative EBITDA for purposes of clause
(c)(i) above), in each case to the Company or any Restricted Subsidiary from any
Person or (B) the redesignation of any Unrestricted Subsidiary as a Restricted
Subsidiary, not to exceed, in the case of (A) or (B), the amount of such
Investments previously made by the Company and its Restricted Subsidiaries in
such Person which were treated as Restricted Payments.

                  Notwithstanding the foregoing limitation, the Company may (a)
pay dividends on its Capital Stock within 60 days of the declaration thereof if,
on the declaration date, such dividends could have been paid in compliance
herewith, (b) redeem, repurchase, defease, acquire or retire for value, any
Indebtedness subordinate (whether pursuant to its terms or by operation of law)

Company or Indebtedness subordinate (whether pursuant to its terms or by
operation of law) in right of payment to the Securities in exchange for or in
connection with a substantially concurrent issuance of, Capital Stock of the
Company (other than Redeemable Stock and other than Capital Stock issued or sold
to a Subsidiary or an employee stock ownership plan or other trust established
by the Company or any Subsidiary), and (d) make Investments in Persons the

                  Any payments made pursuant to clauses (b) and (c) of the
immediately preceding paragraph shall be excluded from the calculation of the
aggregate amount of Restricted Payments made after the Issue Date; PROVIDED,
HOWEVER, that the proceeds from the issuance of Capital Stock pursuant to clause
(c) of the immediately preceding paragraph shall not constitute Capital Stock
Sale Proceeds for purposes of clause (c)(ii) of the first paragraph of this

any service) with, or for the benefit of, any Affiliate of the Company (an
"Affiliate Transaction") unless (a) the terms of such Affiliate Transaction are
(i) set forth in writing, (ii) in the best interest of the








                                                                              81







Company or such Restricted Subsidiary, as the case may be, and (iii) no less
favorable to the Company or such Restricted Subsidiary, as the case may be, than
those that could be obtained in a comparable arm's-length transaction with a
Person that is not an Affiliate of the Company or such Restricted Subsidiary,
(b) with respect to an Affiliate Transaction involving aggregate payments or
value in excess of $1,000,000, the Board of Directors of the Company (including
a majority of the Disinterested Directors of the Company) approves such
Affiliate Transaction and, in its good faith judgment, believes that such
Affiliate Transaction complies with clauses (a)(ii) and (iii) of this paragraph
as evidenced by a Board Resolution and (c) with respect to an Affiliate
Transaction involving aggregate payments or value in excess of $10,000,000, the
Company obtains a written opinion from an independent appraisal firm to the
effect that such Affiliate Transaction is fair from a financial point of view.

enter into or suffer to exist the following: (i) any transaction pursuant to any
contract in existence on the Issue Date and listed on Schedule II; (ii) any

Company or any of its Restricted Subsidiaries, so long as the Board of Directors
of the Company in good faith shall have approved the terms thereof and deemed
the services theretofore or thereafter to be performed for such compensation or
fees to be fair consideration therefor; (v) loans and advances to employees made
in the ordinary course of business and consistent with past practice of the
Company or such Restricted Subsidiary, as the case may be, provided, that such
loans and advances do not exceed $5,000,000 at any one time outstanding; (vi)
employment arrangements entered into in the ordinary course of business with
officers of the Company approved by a majority of the Disinterested Directors of
the Company; and (vii) the Management Services Agreement.

Subsidiary to, directly or indirectly, Incur or suffer to exist, any Lien (other
than Permitted Liens) upon any of its Property, whether now owned or hereafter
acquired, including any Lien on any interest in, or any income or profits from,
its Property, unless effective provision has been or will be made whereby the
Securities will be secured equally and ratably with (or prior to) such
obligation; PROVIDED, HOWEVER, that no Lien

                  SECTION 1016.  Purchase of Securities upon a Change of
Control.

                  (a) If a Change of Control shall occur at any time, then each
Holder of Securities shall have the right to require that the Company purchase

         to the Change of Control Offer shall cease to accrete or accrue
         interest after the Change of Control Purchase Date;

                  (4) that any Securities (or portions thereof) not tendered

         constituting the Change of Control; and









                                                                              83

         payment.

                  (c) The Company will comply, to the extent applicable, 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 purchase of Securities in connection with a
Change of Control. To the extent that the provisions of any securities laws or
regulations conflict with the provisions relating to the Change of Control
Offer, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations described

                  SECTION 1017. Limitation on Assets Sales.

                  (a) The Company shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, consummate any Asset Sale after the Issue
Date unless (i) the Company or such 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 Property subject to such Asset Sale and (ii) at least 80% of
the consideration paid to the Company or such Restricted Subsidiary in
connection with such Asset Sale is in the form of cash or cash equivalents.

                  (b) The Net Available Cash (or any portion thereof) from Asset
Sales may be applied by the Company or a Restricted Subsidiary, to the extent
the Company or such Restricted Subsidiary elects, (A) to prepay, repay or
purchase Indebtedness of a Restricted Subsidiary (excluding Indebtedness owed to
the Company or an Affiliate of the Company); or (B) to reinvest in Additional
Assets (including by means of an Investment in Additional Assets by a Restricted
Subsidiary with Net Available Cash received by the Company or another Restricted
Subsidiary).

                  (c) Any Net Available Cash from an Asset Sale is not applied
in accordance with the preceding paragraph within 270 days from the date of such
Asset Sale or the receipt of such Net Available Cash shall constitute "Excess
Proceeds". When the aggregate amount of Excess Proceeds exceeds $10,000,000
(taking into account income earned on such Excess Proceeds), the Company will be
required to make an offer to purchase (the "Prepayment Offer") the Securities,
on a pro rata basis according to principal amount at maturity, at a purchase
price equal to 100% of the Accreted Value thereof plus accrued and unpaid
interest thereon (if any) to the date of purchase in accordance with the
procedures (including prorating in the event of








                                                                              84







oversubscription) set forth herein. If the aggregate Accreted Value of
Securities surrendered for purchase by Holders thereof exceeds the amount of
Excess Proceeds, then the Trustee shall select the Securities to be purchased
pro rata according to Accreted Value of the Securities tendered in response to
the Prepayment Offer or by lot with such adjustments as may be deemed
appropriate by the Company so that only Securities having a principal amount of
maturity of $1,000, or integral multiples thereof, shall be purchased. To the
extent that any portion of the amount of Net Available Cash remains after
compliance with the preceding sentence and provided that all Holders of
Securities have been given the opportunity to tender their Securities for
purchase as described in the following paragraph, the Company or such Restricted
Subsidiary may use such remaining amount for general corporate purposes and the
amount of Excess Proceeds will be reset to zero.

                  (d) Within five Business Days after the Excess Proceeds
exceeds $10,000,000, the Company shall send a written notice, by first-class
mail, to the Holders (the "Prepayment Offer Notice"), accompanied by such
information regarding the Company and its Subsidiaries as the Company in good
faith believes will enable such Holders to make an informed decision with
respect to the Prepayment Offer. The Prepayment Offer Notice will state, among
other things, (1) that the Company is offering to purchase Securities pursuant
to the provisions of this Section 1017, (2) the purchase price and purchase
date, which shall be, subject to any contrary requirements of applicable law, no
less than 30 days not more than 60 days from the date the Prepayment Offer
Notice is mailed (the "Purchase Date"), (3) that any Security (or any portion
thereof) accepted for payment (and duly paid on the Purchase Date) pursuant to
the Prepayment Offer shall cease to accrete original issue discount or accrue
interest after the Purchase Date, (4) the aggregate Accreted Value of Securities
(or portion thereof) to be purchased and (5) a description of the procedure that
Holders must follow in order to tender their Securities (or portions thereof)
and the procedure that Holders must follow in order to withdraw an election to
tender their Securities (or portions thereof) for payment.

                  (e) The Company will comply, to the extent applicable with
Rule 14e-1 under the Exchange Act and any other securities laws or regulations
thereunder to the extent such laws and regulations are applicable in connection
with the purchase of Securities pursuant to this Section. To the extent that the
provisions of any securities laws or regulations conflict with the provisions
relating to the Prepayment Offer, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its
obligations described in this Section by virtue thereof.

only, to (i) any encumbrance or restriction relating to Indebtedness that is
permitted to be Incurred and secured pursuant to the provisions under Section

assets or Property securing such Indebtedness, (ii) any encumbrance or
restriction in connection with an acquisition of Property, so long as such
encumbrance or restriction relates solely to the Property so acquired and was
not created in connection with or in anticipation of such acquisition, (iii)
customary provisions restricting subletting or assignment of leases and
customary provisions in other agreements that restrict assignment of such
agreements or rights thereunder or (iv) customary restrictions contained in
asset sale agreements limiting the transfer of such assets pending the closing
of such sale.

at least $ 112,000,000 aggregate principal amount at maturity of Securities must
remain outstanding after each such redemption.

                  SECTION 1102.  Applicability of Article.

                  Redemption of Securities at the election of the Company or
otherwise, as permitted or required by any provision of this Indenture, shall be
made in accordance with such provision and this Article.









                                                                              87







                  SECTION 1103.  Notice to Trustee of Redemption.

                  The election of the Company to redeem any Securities pursuant
to paragraph (b) of Section 1101 shall be evidenced by a Board Resolution. In
case of any redemption at the election of the Company, the Company shall, at
least 60 days prior to the Redemption Date fixed by the Company (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities to be redeemed and
shall deliver to the Trustee such documentation and records as shall enable the
Trustee to select the Securities to be redeemed pursuant to Section 1104.

                  SECTION 1104. Selection by Trustee of Securities to Be
Redeemed.

                  If less than all the Securities are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee, from the Outstanding Securities not
previously called for redemption, by such method as the Trustee shall deem fair
and appropriate and which may provide for the selection for redemption of
portions of the principal of Securities; PROVIDED, HOWEVER, that no such partial
redemption shall reduce the portion of the principal amount of a Security not
redeemed to less than $1,000.

                  The Trustee shall promptly notify the Company in writing of
the Securities selected for redemption and, in the case of any Securities
selected for partial redemption, the principal amount thereof to be redeemed.

                  For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to redemption of Securities shall
relate, in the case of any Security redeemed or to be redeemed only in part, to
the portion of the principal amount of such Security which has been or is to be
redeemed.

                  SECTION 1105.  Notice of Redemption.

                  Notice of redemption shall be given in the manner provided for
in Section 106 not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed. The notice if given in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Holder receives such notice. In any case, failure to give
such notice or any defect in the notice to the Holder of any Security designated
for redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security.









                                                                              88







                  All notices of redemption shall state:

                  (1)  the Redemption Date,

                  (2) the Redemption Price and the amount of accrued interest to
         the Redemption Date payable as provided in Section 1107, if any,

                  (3) if less than all Outstanding Securities are to be
         redeemed, the identification (and, in the case of a partial redemption,
         the principal amounts) of the particular Securities to be redeemed,

                  (4) in case any Security is to be redeemed in part only, the
         notice which relates to such Security shall state that on and after the
         Redemption Date, upon surrender of such Security, the Holder will
         receive, without charge, a new Security or Securities of authorized
         denominations for the principal amount thereof remaining unredeemed,

                  (5) that on the Redemption Date the Redemption Price (and
         accrued interest, if any, to the Redemption Date payable as provided in
         Section 1107) will become due and payable upon each such Security, or
         the portion thereof, to be redeemed, and that interest thereon will
         cease to accrue on and after said date, and

                  (6) the place or places where such Securities are to be
         surrendered for payment of the Redemption Price and accrued interest,
         if any.

                  Notice of redemption of Securities to be redeemed shall be
given by the Company or, at the Company's request, by the Trustee in the name
and at the expense of the Company.

                  SECTION 1106.  Deposit of Redemption Price.

                  On or prior to 10:00 a.m. (New York City time) on any
Redemption Date, the Company shall deposit with the Trustee or with a Paying
Agent (or, if the Company is acting as its own Paying Agent, segregate and hold
in trust as provided in Section 1003) an amount of money sufficient to pay the
Redemption Price of, and accrued interest on, all the Securities which are to be
redeemed on that date.









                                                                              89







                  SECTION 1107.  Securities Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the
Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified (together with accrued
interest, if any, to the Redemption Date), and from and after such date (unless
the Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to accrete in value or bear interest. Upon
surrender of any such Security for redemption in accordance with said notice,
such Security shall be paid by the Company at the Redemption Price, together
with accrued interest, if any, to the Redemption Date; PROVIDED, HOWEVER, that
installments of interest payable on any Interest Payment Date on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
309.

                  If any Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal (and premium, if any)
shall, until paid, bear interest, or the Security shall accrete in value, as the
case may be, from the Redemption Date at the rate borne by the Securities.

                  SECTION 1108.  Securities Redeemed in Part.

                  Any Security which is to be redeemed only in part shall be
surrendered at the Corporate Trust Office of the Trustee or at the office or
agency of the Company maintained for such purpose pursuant to Section 1002
(with, if the Company or the Trustee so requires, due endorsement by, or a
written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the Holder thereof or such Holder's attorney duly
authorized in writing), and the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge,
a new Security or Securities of like tenor and form, of any authorized
denomination as requested by such Holder, in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.










                                                                              90







                                 ARTICLE TWELVE

                                   [RESERVED]


                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

                  SECTION 1301. Company's Option to Effect Defeasance or
Covenant Defeasance.

                  The Company may, at its option by Board Resolution, at any
time, with respect to the Securities, elect to have Section 1302 or Section 1303
be applied to all Outstanding Securities upon compliance with the conditions set
forth below in this Article Thirteen.

                  SECTION 1302.  Defeasance and Discharge.

                  Upon the Company's exercise under Section 1301 of the option
applicable to this Section 1302, the Company shall be deemed to have been
discharged from its obligations with respect to all Outstanding Securities on
the date the conditions set forth in Section 1304 are satisfied (hereinafter,
"legal defeasance"). For this purpose, such legal defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by the Outstanding Securities, which shall thereafter be deemed to
be "Outstanding" only for the purposes of Section 1305 and the other Sections of
this Indenture referred to in (A) and (B) below, and to have satisfied all its
other obligations under such Securities and this Indenture insofar as such
Securities are concerned (and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging the same), except for the following,
which shall survive until otherwise terminated or discharged hereunder: (A) the
rights of Holders of Outstanding Securities to receive, solely from the trust
fund described in Section 1304 and as more fully set forth in such Section,
payments in respect of the principal of (and premium, if any, on) and interest
on such Securities when such payments are due, (B) the Company's obligations
with respect to such Securities under Sections 304, 305, 308, 1002 and 1003, (C)
the rights, powers, trusts, duties and immunities of the Trustee hereunder and
(D) this Article Thirteen. Subject to compliance with this Article Thirteen, the
Company may exercise its option under this Section 1302 notwithstanding the
prior exercise of its option under Section 1303 with respect to the Securities.









                                                                              91







                  SECTION 1303.  Covenant Defeasance.

                  Upon the Company's exercise under Section 1301 of the option
applicable to this Section 1303, the Company shall be released from its
obligations under any covenant contained in Sections 1005, 1009 through Section
1015 and in Sections 1017 through 1020 inclusive, the operation of Sections
501(5), Section 501(7), 501(8) (with respect to Restricted Subsidiaries only),
501(9) (with respect to Restricted Subsidiaries only) and the limitation
contained in Section 801(4) with respect to the Outstanding Securities on and
after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"), and the Securities shall thereafter be deemed not to be
"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. For this purpose, such covenant defeasance means that, with respect
to the Outstanding Securities, 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 of Default under
Section 501(4), but, except as specified above, the remainder of this Indenture
and such Securities shall be unaffected thereby.

                  SECTION 1304. Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of either
Section 1302 or Section 1303 to the Outstanding Securities:

                  (1) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 607 who shall agree to comply with the
         provisions of this Article Thirteen applicable to it) as trust funds in
         trust for the purpose of making the following payments, specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of such Securities, (A) cash in United States dollars, or (B)
         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, money in an amount, or (C) a combination thereof, sufficient,
         in the opinion of a nationally recognized firm of independent public
         accountants expressed in a written certification thereof delivered to
         the Trustee, to pay and discharge, and which shall be applied by the
         Trustee (or other qualifying trustee) to pay








                                                                              92






         and discharge, (i) the principal of (and premium, if any) and interest
         on the Outstanding Securities on the Stated Maturity (or Redemption
         Date, if applicable) of such principal (and premium, if any) or
         installment of interest and (ii) any mandatory redemption or analogous
         payments applicable to the Outstanding Securities on the day on which
         such payments are due and payable in accordance with the terms of this
         Indenture and of such Securities; PROVIDED that the Trustee shall have
         been irrevocably instructed to apply such cash in United States dollars
         or the proceeds of such U.S. Government Obligations to said payments
         with respect to the Securities. Before such a deposit, the Company may
         give to the Trustee, in accordance with Section 1103 hereof, a notice
         of its election to redeem all of the Outstanding Securities at a future
         date in accordance with Article Eleven hereof, which notice shall be
         irrevocable. Such irrevocable redemption notice, if given, shall be
         given effect in applying the foregoing.

                  (2) No (a) Default in the payment of principal of or premium,
         if any, or interest on any Security or a Default resulting from the
         occurrence of an Event of Default specified in Section 501(8) or (9)
         (without regard to any passage of time specified therein) or (b) Event
         of Default with respect to the Securities (other than as a result of a
         breach of the provisions of Article Eight arising from a merger or
         consolidation occurring contemporaneously with such defeasance) shall
         have occurred and be continuing on the date of, or immediately after,
         such deposit or, insofar as paragraphs (8) and (9) of Section 501
         hereof are concerned, at any time during the period ending on the 91st
         day after the date of such deposit (it being understood that this
         condition shall not be deemed satisfied until the expiration of such
         period).

                  (3) Such legal defeasance or covenant defeasance shall not
         result in a breach or violation of, or constitute a default under, any
         material agreement or instrument to which the Company is a party or by
         which it is bound.

                  (4) In the case of an election under Section 1302, the Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (x) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (y) since the Issue Date, there
         has been a change in the applicable federal income tax law, in either
         case to the effect that, and based thereon such opinion shall confirm
         that, the Holders of the Outstanding Securities will not recognize
         income, gain or loss for federal income tax purposes as a result of
         such 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 defeasance had not occurred.








                                                                              93







                  (5) In the case of an election under Section 1303, the Company
         shall have delivered to the Trustee an Opinion of Counsel to the effect
         that the Holders of the Outstanding Securities will not recognize
         income, gain or loss for federal income tax purposes as a result of
         such covenant defeasance and will be subject to federal income tax on
         the same amounts, in the same manner and at the same times as would
         have been the case if such covenant defeasance had not occurred.

                  (6) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel, each stating that all
         conditions precedent provided for relating to either the legal
         defeasance under Section 1302 or the covenant defeasance under Section
         1303 (as the case may be) have been complied with.

                  SECTION 1305.  Deposited Money and U.S. Government Obligations
To Be Held in Trust; Other Miscellaneous Provisions.

                  Subject to the provisions of the last paragraph of Section
1003, all money and U.S. Government Obligations (including the proceeds thereof)
deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 1305, the "Trustee") pursuant to Section 1304 in
respect of the Outstanding Securities shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Governmental
Obligations deposited pursuant to Section 1304 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of the Outstanding Securities.

                  Anything in this Article Thirteen to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to
time upon Company Request any money or U.S. Government Obligations held by it as
provided in Section 1304 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 which would then
be required to be deposited to effect








                                                                              94






all equivalent defeasance or covenant defeasance, as applicable, in accordance
with this Article.

                  SECTION 1306.  Reinstatement.

                  If the Trustee or any Paying Agent is unable to apply any
money in accordance with Section 1305 by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 1302 or 1303, as the case may be (until such time as the
Trustee or Paying Agent is permitted to apply all such money), in accordance
with Section 1305; PROVIDED, HOWEVER, that if the Company makes any payment of
principal of (or premium, if any) or interest on any Security following the
reinstatement of its obligations, the Company shall be subrogated to the rights
of the Holders of such Securities to receive such payment front the money held
by the Trustee or Paying Agent.










                                                                              95

                          Senior Discount Note due 2003



1.       Principal and Interest.

                  The Company will pay the principal of this Note on August 1,
2003.

                  The Company promises to pay interest on the principal amount
of this Note on each Interest Payment Date, as set forth below, [at the rate of
14% per annum (subject to adjustment as provided below)]** [at the rate of 14%
per annum, except that interest accrued on this Note (or the predecessor Note
hereto) pursuant to the second succeeding paragraph of this Section 1 for
periods prior to the applicable Exchange Date (as such term is defined in the
Registration Rights Agreement referred to below) will accrue at the rate or
rates borne by the predecessor Note hereto from time to time during such periods
pursuant to the Registration Rights Agreement as set forth below].*

                  Interest will be payable semiannually (to the holders of
record of the Notes (or any predecessor Notes) at the close of business on the
January 15 or July 15 immediately preceding the Interest Payment Date) on each
Interest Payment Date, commencing February 1, 2000; provided that no interest
shall accrue on the principal amount of this Note prior to August 1, 1999 and no
interest shall be paid on this Note prior to February 1, 2000 except as provided
in the next paragraph.

                  The Holder of this Note is entitled to the benefits of the
Exchange and Registration Rights Agreement, dated July 30, 1996, between the
Company and the Initial Purchasers named therein (the "Registration Rights
Agreement"). In the event that either (a) the Exchange Offer Registration
Statement (as such term is defined in the Registration Rights Agreement) is not
filed with the Securities and Exchange Commission on or prior to the 45th
calendar day following the date of original issue of the Notes, (b) the Exchange
Offer Registration Statement has not been declared effective on or prior to the
120 calendar days following the date of original issue of the Notes; (c) either

**       Include only for Initial Securities.






                                       A-5




the Exchange Offer (as such term is defined in the Registration Rights
Agreement) is not consummated or the Shelf Registration Statement (as such term
is defined in the Registration Rights Agreement) is not declared effective
within 150 calendar days following the date of original issue of the Notes, or
(d) the Exchange Offer Registration Statement or the Shelf Registration
Statement is declared effective, but thereafter ceases to be effective or usable
(each such event referred to in clause (a) through (d) above, a "Registration
Default") interest (in addition to the accrual of original issue discount during
the period ending August 1, 1999, and in addition to the interest otherwise due
on the Notes after such date) will accrue on this Note at a rate of one-half of
one percent per annum of the Accreted Value on the immediately preceding
semi-annual accrual date (for purposes of this paragraph, "semi-annual accrual
date" means each February 1 or August 1 of each year (or, if such immediately
preceding February 1 or August 1 occurs before February 1, 1997, at a rate of
one-half of one percent of the Accreted Value of this Note on August 1, 1996))
with respect to the first 90-day period following such Registration Default, and
the amount of such additional interest will increase by an additional one-half
of one percent per annum for each subsequent 90-day period until such
Registration Default has been cured, payable in cash semi-annually, in arrears,
on February 1 and August 1 of each year; PROVIDED, HOWEVER, that in no event
shall the rate of such additional interest be more than one and one-half of one
percent. Upon the cure of all applicable Registration Defaults, such additional
interest shall cease to accrue.

                  Any and all payments made by the Company under this Note will
be made free and clear of and without deduction for or on account of any and all
present or future taxes, levies, imposts, deductions, charges or withholdings
and all liabilities with respect thereto imposed by the United States excluding
any taxes, levies, imposts, deductions, charges or withholdings and all
liability with respect thereto (i) resulting from the Holder having some
connection with the United States other than the mere holding of or enforcement
of or receipt of any payment with respect to such Note, (ii) the payment of
which may be avoided by the Holder complying with any certification, declaration
or other reporting requirement concerning the nationality, residence, identity
or connection with any taxing authority of such Holder as the beneficial owner
of such Note, (iii) that would not have been imposed but for the presentation
(where presentation is required) of such Note for payment more than 30 days
after the date such payment became due and payable or was duly provided for,
whichever occurs later, (iv) in the nature of estate, inheritance, gift, sale,
transfer, personal property or similar taxes or (v) imposed on or with respect
to any payment by the Company to the Holder if such Holder is a fiduciary or
partnership or person other than the sole beneficial owner of such payment to
the extent such tax, levy, impost, deduction, charge or withholding would not
have been imposed on a beneficiary or settlor with respect to such fiduciary,
member of such partnership or








                                       A-6



the beneficial owner of such payment had such beneficiary, settlor, member or
beneficial owner been the Holder of such Note (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
referred to collectively or individually as "U.S. Withholding Taxes"). If the
Company is required by law to deduct any U.S. Withholding Taxes from or in
respect of any sum payable under this Note, the sum payable hereunder shall be
increased by the amount necessary so that after making all required deductions
the Holder will receive an amount equal to the sum it would have received had no
such deductions been made.

                  From and after August 1, 1999, interest on this Note will
accrue from the most recent date to which interest has been paid [on this Note
or the Note surrendered in Exchange herefor]* or, if no interest has been paid,
from August 1, 1999; provided that, if there is no existing default in the
payment of interest and if this Note is authenticated between a Regular Record
Date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such Interest Payment Date. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

                  The Company shall pay interest on overdue principal and
premium, if any, and interest on overdue installments of interest, to the extent
lawful, at a rate per annum equal to the rate of interest applicable to the
Notes.

2.       Method of Payment.

                  The Company will pay interest (except Defaulted Interest) on
the principal amount of the Notes on each February 1 and August 1 to the persons
who are Holders (as reflected in the Security Register at the close of business
on the January 15 and July 15 immediately preceding the Interest Payment Date),
in each case, even if the Note is cancelled on registration of transfer or
registration of exchange after such record date; provided that, with respect to
the payment of principal, the Company will make payment to the Holder that
surrenders this Note to any Paying Agent on or after August 1, 2003.



_________________

*        Include only for Exchange Securities.

                  The Company will pay principal, premium, if any, and interest
in money of the United States that at the time of payment is legal tender for
payment of








                                       A-7




public and private debts. However, the Company may pay principal, premium, if
any, and interest by its check payable in such money. The Company may mail an
interest check to a Holder's registered address (as reflected in the Security
Register). The Company may also make any payment of monies required to be
deposited with the Trustee on account of principal of, or premium, if any, or
interest on, this Note by wire transfer in immediately available funds to an
account designated by the Trustee on or before the date such monies are to be
paid to the Holder. If a payment date is a date other than a Business Day,
payment may be made on the next succeeding day that is a Business Day and no
interest shall accrue for the intervening period.

3.       Intentionally Omitted.


4.       Paying Agent and Registrar.

                  Initially, the Trustee will act as authenticating agent,
Paying Agent and Registrar. The Company may change any authenticating agent,
Paying Agent or Registrar upon written notice thereto. The Company, any
Subsidiary or any Affiliate of any of them may act as Paying Agent, Registrar or
co-registrar.

5.       Indenture; Limitations.

                  The Company issued the Notes under an Indenture dated as of
August 1, 1996 (the "Indenture"), between the Company and Fleet National Bank as
trustee (the "Trustee"). Capitalized terms herein are used as defined in the
Indenture unless otherwise indicated. The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act. The Notes are subject to all such terms, and Holders are
referred to the Indenture and the Trust Indenture Act for a statement of all
such terms. To the extent permitted by applicable law, in the event of any
inconsistency between the terms of this Note and the terms of the Indenture, the
terms of the Indenture shall control.

                  The Notes are general unsecured obligations of the Company.
The Indenture limits the aggregate principal amount of the Notes to
$142,000,000.

6.       Redemption.

                  Mandatory Redemption. The Company will redeem 100% of the
principal amount, together with accrued and unpaid interest to the redemption
date from the Holders of the Notes at the close of business on August 1, 2003.








                                       A-8


                  Optional Redemption. The Notes are not redeemable prior to
August 1, 2000. At any time on or after August 1, 2000, the Notes are redeemable
at the option of the Company, in whole or in part, on not less than 30 nor more
than 60 days' notice, at the following redemption prices (expressed as
percentages of Accreted Value), plus accrued and unpaid interest (if any) to the
date of redemption:

                  If redeemed during the 12-month period commencing August 1 of
the year indicated:

                                                                      REDEMPTION
YEAR                                                                    PRICE
2000.................................................................   107.0%
2001.................................................................   103.5%
2002 and thereafter..................................................   100.0%


                  Notwithstanding the foregoing, at any time and from time to
time prior to August 1, 1999, the Company may redeem in the aggregate up to
$30,000,000 of the principal amount at maturity of the Notes with the proceeds
of one or more Public Equity Offerings, at a redemption price (expressed as a
percentage of Accreted Value) of 114%, PROVIDED, HOWEVER, that at least
$112,000,000 aggregate principal amount at maturity of Notes must remain
outstanding after each such redemption.

                  On and after any redemption date, interest will cease to
accrete or accrue on the Notes or portions thereof called for redemption unless
the Company shall fail to redeem any such Notes.

7.       Repurchase upon a Change of Control.

                  Upon the occurrence of a Change in Control, each Holder shall
have the right to require that the Company repurchase such Holder's Notes, in
whole or in part, in integral multiples of $1,000 principal amount at final
Maturity, at a purchase price in cash in an amount equal to 101% of the Accreted
Value thereof, plus accrued interest (if any) to the date of purchase (the
"Change of Control Purchase Price").

                  A notice of each Change in Control will be mailed within 15
days after such Change of Control occurs to each Holder at his last address as
it appears in the Security Register. On and after the Change of Control Payment
Date, interest ceases to accrue on Notes or portions of Notes surrendered for
purchase by the Company, unless the Company defaults in the payment of the
Change of Control Purchase Price.

8.       Denominations; Transfer; Exchange.








                                       A-9



                  The Notes are in registered form without coupons, in
denominations of $1,000 principal amount at maturity and multiples of $1,000 in
excess thereof. A Holder may register the transfer or exchange of Notes in
accordance with the Indenture. The Registrar may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and to pay
any taxes and fees required by law or permitted by the Indenture. The Registrar
need not register the transfer or exchange of any Notes selected for redemption
(except the unredeemed portion of any Note being redeemed in part). Also, it
need not register the transfer or exchange of any Notes for a period of 15 days
before a selection of Notes to be redeemed is made.

9.       Persons Deemed Owners.

                  A Holder may be treated as the owner of a Note for all
purposes.

10.       Unclaimed Money.

                  If money for the payment of principal, premium, if any, or
interest remains unclaimed for two years, the Trustee and the Paying Agent will,
subject to escheat law, pay the money back to the Company at its request. After
that, Holders entitled to the money must look to the Company for payment, unless
an abandoned property law designates another Person, and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

11.      Amendment; Supplement; Waiver.

                  Subject to certain exceptions, the Indenture or the Notes may
be amended or supplemented with the consent of the Holders of at least a
majority in aggregate principal amount at final Maturity of the Notes then
outstanding, and any existing default or compliance with any provision may be
waived with the consent of the Holders of a majority in aggregate principal
amount at final Maturity of the Notes then outstanding. Without notice to or the
consent of any Holder, the parties thereto may amend or supplement the Indenture
or the Notes to, among other things, cure any ambiguity, or inconsistency
provided such change does not materially adversely affect the rights of any
Holder.

12.       Restrictive Covenants.

                  The Indenture imposes certain limitations on the ability of
the Company and its Subsidiaries, among other things, to incur additional
Indebtedness, grant Liens, make Restricted Payments, use the proceeds from Asset
Sales, engage in








                                      A-10




transactions with Affiliates, engage in other businesses, restrict payments from
Restricted Subsidiaries or merge, consolidate or transfer substantially all of
its assets. At the end of each fiscal year, the Company must report to the
Trustee on compliance with such limitations.

13.       Successor Persons.

                  When a successor person or other entity assumes all the
obligations of its predecessor under the Notes and the Indenture, the
predecessor person will be released from those obligations.

14.       Defaults and Remedies.

                  The following events constitute "Events of Default" under the
Indenture: (a) failure to make the payment of any principal of or premium, if
any, on any Note at its Maturity Date (upon acceleration, optional redemption,
required purchase or otherwise); (b) failure to make the payment of any interest
on any Note when it becomes due and payable and any such failure continues for a
period of 30 days; (c) failure to comply with any covenant or warranty of the
Company contained in the Indenture (other than a covenant or warranty that is
specifically dealt with in clauses (a) or (b) above) which failure continues for
a period of 30 days after written notice shall have been given to the Company by
the Trustee or to the Company and the Trustee by the holders of at least 25% in
aggregate principal amount of the Notes then outstanding; (d) (i) Indebtedness
of the Company or any Restricted Subsidiary in an amount greater than $5,000,000
shall have been accelerated or otherwise declared due and payable, or required
to be prepaid or repurchased (other than by regularly scheduled required
prepayment prior to the stated maturity thereof) or (ii) a default by the
Company or any Restricted Subsidiary in the payment of principal on Indebtedness
of the Company or any Restricted Subsidiary in an amount greater than
$5,000,000, when the same becomes due and payable at the stated maturity
thereof, and such default shall have continued after any applicable grace period
and shall not have been cured or waived; (e) one or more final judgments or
orders shall be rendered against the Company or any Restricted Subsidiary for
the payment of money in an uninsured aggregate amount, in excess of $5,000,000
shall not be waived, satisfied or discharged for any period of 30 consecutive
days during which a stay of enforcement of such judgment or order was not in
effect; or (f) the occurrence of certain events of bankruptcy, insolvency or
reorganization with respect to the Company or any Subsidiary.

                  If an Event of Default, as defined in the Indenture, occurs
and is continuing, the Trustee or the Holders of at least 25% in aggregate
principal amount





                                      A-11




at final Maturity of the Notes then outstanding may declare all the Notes to be
immediately due and payable. If a bankruptcy or insolvency Event of Default with
respect to the Company or any of its Subsidiaries occurs and is continuing, the
Notes automatically become immediately due and payable. Holders may not enforce
the Indenture or the Notes except as provided in the Indenture. The Trustee may
require indemnity satisfactory to it before it enforces the Indenture or the
Notes. Subject to certain limitations, Holders of at least a majority in
aggregate principal amount at final Maturity of the Notes then outstanding may
direct the Trustee in its exercise of any trust or power.

15.       Trustee Dealings with Company.

                  The Trustee under the Indenture, in its individual or any
other capacity, may become the owner or pledgee of Notes and may make loans to,
accept deposits from, perform services for, and otherwise deal with, the Company
and its Affiliates as if it were not the Trustee.

16.       Authentication.

                  This Note shall not be valid until the Trustee or
authenticating agent signs the certificate of authentication on the other side
of this Note.

17.       Abbreviations.

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

18.       Defeasance.

                  The Indenture contains provisions for defeasance, at any time,
of the Indebtedness represented by this Note or the covenants governing the
Indebtedness represented by this Note, upon compliance by the Company with
certain conditions set forth in the Indenture.

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

Ladies and Gentlemen:

                  In connection with our proposed purchase of $ _______________ 
aggregate principal amount of the Securities:

                  1. We understand that the Securities have not been registered
         under the Securities Act of 1933, as amended (the "Securities Act"),
         and may not be sold except as permitted in the following sentence. We
         agree on our own behalf and on behalf of any investor account for which
         we are purchasing the Securities to offer, sell or otherwise transfer
         such Securities prior to the date which is three years after the later
         of the date of original issue and the last date on which the Company or
         any affiliate of the Company was the owner of such Securities, or any
         predecessor thereto (the "Resale Restriction Termination Date") only
         (a) to the Company, (b) pursuant to a registration statement which has
         been declared effective under the Securities Act, (c) for so long as
         the Securities are eligible for resale pursuant to Rule 144A under the
         Securities Act, to a person we reasonably believe is a qualified
         institutional buyer under Rule 144A (a "QIB") that purchases for its
         own account or for the account of a QIB to whom notice is given that
         the transfer is being made in reliance on Rule 144A, (d) pursuant to
         offers and sales to non-U.S. Persons that occur outside the United
         States within the meaning of Regulation S under the Securities Act, (e)
         to an institutional "accredited investor" within the meaning of
         subparagraph (a)(1), (2), (3) or (7) of Rule 501 under the Securities
         Act that is acquiring the Securities for its own account or for the




                                       C-2



         account of such an institutional "accredited investor" for investment
         purposes and not with a view to, or for offer or sale in connection
         with, any distribution thereof in violation of the Securities Act or
         (f) pursuant to any other available exemption from the registration
         requirements of the Securities Act, subject in each of the foregoing
         cases to any requirement of law that the disposition of our property
         and the property of such investor account or accounts be at all times
         within our or their control and to compliance with any applicable state
         securities laws. The foregoing restrictions on resale will not apply
         subsequent to the Resale Restriction Termination Date. If any resale or
         other transfer of the Securities is proposed to be made pursuant to
         clause (e) above prior to the Resale Restriction Termination Date, the
         transferor shall deliver a letter from the transferee substantially in
         the form of this letter to the Trustee, which shall provide, among
         other things, that the transferee is an institutional "accredited
         investor" within the meaning of subparagraph (a)(1), (2), (3) or (7) or
         Rule 501 under the Securities Act and that it is acquiring such
         Securities for investment purposes and not for distribution in
         violation of the Securities Act. We acknowledge that the Company and
         the Trustee reserve the right prior to any offer, sale or other
         transfer prior to the Resale Restriction Termination Date of the
         Securities pursuant to clauses (d), (e) and (f) above to require the
         delivery of an opinion of counsel, certifications and/or other
         information satisfactory to the Company and the Trustee.

                  2. We are an institutional "accredited investor" (as defined
         in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities
         Act) purchasing for our own account or for the account of such an
         institutional "accredited investor," and we are acquiring the
         Securities for investment purposes and not with a view to, or for offer
         or sale in connection with, any distribution in violation of the
         Securities Act and we have such knowledge and experience in financial
         and business matters as to be capable of evaluating the merits and
         risks of our investment in the Securities, and we and any accounts for
         which we are acting are each able to bear the economic risk of our or
         its investment.

                  3. We are acquiring the Securities purchased by us for our own
         account or for one or more accounts as to each of which we exercise
         sole investment discretion.





                                       C-3

         inquiry with respect to the matters covered hereby.
