                         INDENTURE, dated as of May 15, 1999, between CD RADIO
                    INC., a corporation duly organized and existing under the
                    laws of the State of Delaware (herein called the "Company"),
                    having its principal office at 1221 Avenue of the Americas,
                    New York, NY 10020, and UNITED STATES TRUST COMPANY OF NEW
                    YORK, a bank duly organized and existing under the laws of
                    the State of New York, Trustee (herein called the
                    "Trustee").

          The Company has duly authorized the creation of an issue of 14 1/2%
Senior Secured Notes due 2009 (herein called the "Initial Notes") and, if and
when issued pursuant to a registered exchange for Initial Notes, the 14 1/2%
Senior Secured Notes due 2009 (herein called the "Exchange Notes", together with
the Initial Notes, the "Notes") 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.

          The Notes have been issued as part of 200,000 Units, each unit
consisting of $1,000 principal amount of Notes and three Warrants to purchase
3.65 shares of the Company's Common Stock (the "Warrants").

          The Company has determined to secure its obligations in respect of the
Notes and duly authorized the execution and delivery of the Collateral Documents
(as defined herein) to which it is a party.

          This Indenture is 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.

          All things necessary have been done to make the Notes, 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.

          For and in consideration of the premises and the purchase of the Notes
by the Holders thereof, it is mutually









covenanted and agreed, for the equal and proportionate benefit of all Holders of
the Notes, as follows:

                                    ARTICLE I

                        Definitions and Other Provisions
                             of General Application

          SECTION 1.01. Definitions. For all purposes of this Indenture, except
as otherwise expressly provided or unless the context otherwise requires:

          (a) the terms defined in this Article I have the meanings assigned to
     them in this Article I, and include the plural as well as the singular;

          (b) all other terms used herein which are defined in the Trust
     Indenture Act, either directly or by reference therein, have the meanings
     assigned to them therein, and the terms "cash transaction" and "self-
     liquidating paper", as used in TIA Section 311, shall have the meanings
     assigned to them in the rules of the Commission adopted under the Trust
     Indenture Act;

          (c) all accounting terms not otherwise defined herein have the
     meanings assigned to them in accordance with United States generally
     accepted accounting principles, and, except as otherwise herein expressly
     provided, the term "generally accepted accounting principles" with respect
     to any computation required or permitted hereunder shall mean such
     accounting principles as are generally accepted at the date of such
     computation; and

          (d) the words "herein", "hereof" and "hereunder" and other words of
     similar import refer to this Indenture as a whole and not to any particular
     Article, Section or other subdivision.

          "Acquired Indebtedness" means Indebtedness of a Person (1) existing at
the time such Person becomes a Restricted Subsidiary or (2) assumed in
connection with the acquisition of assets from such Person, in each case, other
than Indebtedness incurred in connection with, or in contemplation of, such
Person becoming a Restricted Subsidiary or such acquisition; provided that, for
purposes of Section 10.11, such Indebtedness shall be deemed to be incurred on
the date of the related acquisition of assets


                                       -2-








from any Person or the date the acquired Person becomes a Restricted Subsidiary.

          "Act", when used with respect to any Holder, has the meaning specified
in Section 1.04.

          "Adjusted Consolidated Operating Cash Flow" means Consolidated
Operating Cash Flow for the latest four fiscal quarters for which consolidated
financial statements of Company are available, taken as a whole. For purposes of
calculating "Consolidated Operating Cash Flow" for any four fiscal quarter
period for purposes of this definition,

          (1) all Restricted Subsidiaries of the Company on the date of the
     transaction giving rise to the need to calculate "Adjusted Consolidated
     Operating Cash Flow" (the "Transaction Date") shall be deemed to have been
     Restricted Subsidiaries at all times during such four fiscal quarter period
     and

          (2) any Unrestricted Subsidiary on the Transaction Date shall be
     deemed to have been an Unrestricted Subsidiary at all times during such
     four fiscal quarter period.

In addition to and without limitation of the foregoing, for purposes of this
definition, "Consolidated Operating Cash Flow" shall be calculated after giving
effect on a pro forma basis for the applicable four fiscal quarter period to,
without duplication,

          (1) any Asset Sales or Asset Acquisitions (including any Asset
     Acquisition giving rise to the need to make such calculation as a result of
     the Company or a Restricted Subsidiary (including any Person who becomes a
     Restricted Subsidiary as a result of the Asset Acquisition) incurring,
     assuming or otherwise being liable for Acquired Indebtedness) occurring
     during the period commencing on the first day of such four fiscal quarter
     period to and including the Transaction Date (the "Reference Period"), as
     if such Asset Sale or Asset Acquisition occurred on the first day of the
     Reference Period and

          (2) any incurrence or repayment, retirement or permanent reduction of
     any Indebtedness of the Company or any Restricted Subsidiary during the
     Reference Period, as if such incurrence, repayment, retirement or reduction
     occurred on the first day of the Reference Period.


                                       -3-

Person directly or indirectly controlling or controlled by or under direct or
indirect common control with such specified Person or (2) any other Person that

Stock or any executive officer or director of any such specified Person or other
Person or, with respect to any natural Person, any Person having a relationship
with such Person by blood, marriage or adoption not more remote than first
cousin. For the purposes of this definition, "control", when used with respect
to any specified Person, means the power to direct the management and policies
of such Person, directly or indirectly, whether through the ownership of voting
securities, by contract or otherwise; and the terms "controlling" and
"controlled" have meanings correlative to the foregoing.

          "Asset Acquisition" means (1) any capital contribution (by means of
transfers of cash or other property to others or payments for property or
services for the account or use of others, or otherwise) by the Company or any
Restricted Subsidiary in any other Person, or any acquisition or purchase of
Capital Stock of any other Person by the Company or any Restricted Subsidiary,
in either case pursuant to which such Person shall become a Restricted
Subsidiary or shall be merged with or into the Company or any Restricted
Subsidiary or (2) any acquisition by the Company or any Restricted Subsidiary of

reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such

          SECTION 1.04. Acts of Holders. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Holders in person or
by agents duly appointed in writing; and, except as herein otherwise expressly
provided, such


                                      -36-








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 1.04.

          (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 Notes held by any
Person, and the date of holding the same, shall be proved by the Note Register.

          (d) If the Company shall solicit from the Holders of Notes 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. Notwithstanding TIA Section
316(c), 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 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


                                      -37-








the requisite proportion of Outstanding Notes have authorized or agreed or
consented to such request, demand, authorization, direction, notice, consent,
waiver or other Act, and for that purpose the Outstanding Notes 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 eleven months after the record date.

          (e) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Note shall bind every future Holder of
the same Note and the Holder of every Note 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 Note.

          SECTION 1.05. 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 of
     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
     first paragraph of this Indenture, or at any other address previously
     furnished in writing to the Trustee by the Company.

          SECTION 1.06. 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 Note 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


                                      -38-








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 1.07. 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 1.08. 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 1.09. Separability Clause. In case any provision in this
Indenture or in the Notes 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.

          SECTION 1.10. Benefits of Indenture. Nothing in this Indenture or in
the Notes, express or implied, shall give to any Person, other than the parties
hereto, any Paying Agent, any Notes Registrar and their successors hereunder,
and the Holders, any benefit or any legal or equitable right, remedy or claim
under this Indenture.

          SECTION 1.11. Governing Law. This Indenture and the Notes shall be
governed by and construed in accordance with the law of the State of New York.

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.

          SECTION 1.12. Legal Holidays. In any case where any Interest Payment
Date, Redemption Date, Stated Maturity or Maturity of any Note shall not be a
Business Day, then (notwithstanding any other provision of this Indenture or of
the Notes) 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 or 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, Stated Maturity or Maturity, as the case may be, to the next Business Day.

thereafter on May 15 and November 15 in each year and at said Stated Maturity,
until the principal thereof is paid or duly provided for. Interest on any
overdue principal amount shall be payable on demand.

          The principal of (premium, if any, on) and interest on the Notes 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 Note Register.

          The Notes shall be redeemable as provided in Article XI.

          SECTION 3.02. Denominations. The Notes shall be issuable only in
registered form without coupons and only denominations of $1,000 and any
integral multiple thereof.

          SECTION 3.03. Execution, Authentication, Delivery and Dating. The
Notes shall be executed on behalf of the Company by its Chairman, its Chief
Executive Officer, its President or a Vice President, and attested by its
Secretary or an Assistant Secretary. The signature of any of these officers on
the Notes may be manual or facsimile signatures of the present or any future
such authorized officer and may be imprinted or otherwise reproduced on the
Notes.


                                      -41-








          Notes 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 Notes or did not hold
such offices at the date of such Notes.

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

          Each Note shall be dated the date of its authentication.

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

          In case the Company, pursuant to Article VIII, 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 indenture supplemental hereto
with the Trustee pursuant to Article VIII, any of the Notes 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 Notes 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 Notes surrendered for such exchange
and of like principal amount; and the Trustee, upon Company Request of the
successor Person, shall authenticate and deliver Notes as specified in such
request for the purpose of such exchange. If Notes


                                      -42-








shall at any time be authenticated and delivered in any new name of a successor
Person pursuant to this Section 3.03 in exchange or substitution for or upon
registration of transfer of any Notes, such successor Person, at the option of
the Holders but without expense to them, shall provide for the exchange of all
Notes at the time Outstanding for Notes authenticated and delivered in such new
name.

          SECTION 3.04. Temporary Notes. Pending the preparation of definitive
Notes, the Company may execute, and upon Company Order the Trustee shall
authenticate and deliver, temporary Notes which are printed, lithographed,
typewritten, mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Notes in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other
variations as the officers executing such Notes may determine, as conclusively
evidenced by their execution of such Notes.

          If temporary Notes are issued, the Company will cause definitive Notes
to be prepared without unreasonable delay. After the preparation of definitive
Notes, the temporary Notes shall be exchangeable for definitive Notes upon
surrender of the temporary Notes at the office or agency of the Company
designated for such purpose pursuant to Section 10.02, without charge to the
Holder. Upon surrender for cancelation of any one or more temporary Notes, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes shall in all respects be
entitled to the same benefits under this Indenture as definitive Notes.

          SECTION 3.05. Registration, Registration of Transfer and Exchange. The
Company shall 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 10.02 being herein sometimes referred to
as the "Note Register") in which, subject to such reasonable regulations as it
may prescribe, the Company shall provide for the registration of Notes and of
transfers of Notes. The Note 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 Note Register shall be open to inspection by the Trustee.
The Trustee is hereby initially appointed as note registrar (the "Note
Registrar") for the


                                      -43-








purpose of registering Notes and transfers of Notes as herein provided.

          Upon surrender for registration of transfer of any Note at the office
or agency of the Company designated pursuant to Section 10.02, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Notes of any authorized
denomination or denominations of a like aggregate principal amount.

          At the option of the Holder, Notes may be exchanged for other Notes of
any authorized denomination and of a like aggregate principal amount, upon
surrender of the Notes to be exchanged at such office or agency. Whenever any
Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes which the Holder making the
exchange is entitled to receive.

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

          Every Note presented or surrendered for registration of transfer or
for exchange shall (if so required by the Company or the Note Registrar) be duly
endorsed, or be accompanied by a written instrument of transfer, in form
satisfactory to the Company and the Note Registrar, duly executed by the Holder
thereof or his attorney duly authorized in writing.

          No service charge shall be made for any registration of transfer or
exchange or redemption of Notes, 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 Notes, other than
exchanges pursuant to Section 3.04, 9.06, 10.10, 10.16 or 11.08 not involving
any transfer.

          The Company shall not be required (i) to issue, register the transfer
of or exchange any Note during a period beginning at the opening of business 15
days before the selection of Notes to be redeemed under Section 11.04 and ending
at the close of business on the day of such mailing of the relevant notice of
redemption, or (ii) to register the transfer of or exchange any Note so selected


                                      -44-








for redemption in whole or in part, except the unredeemed portion of any Note
being redeemed in part.

          SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Notes. If (i) any
mutilated Note 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 Note, 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 Note 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 Note or in lieu of any such destroyed, lost or stolen Note, a new Note
of like tenor and principal amount, bearing a number not contemporaneously
outstanding.

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

          Upon the issuance of any new Note under this Section 3.06, 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 Note issued pursuant to this Section 3.06 in lieu of any
mutilated, destroyed, lost or stolen Note shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Note 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 Notes duly issued hereunder.

          The provisions of this Section 3.06 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Notes.

          SECTION 3.07. Payment of Interest; Interest Rights Preserved. Interest
on any Note which is payable, and is punctually paid or duly provided for, on
any Interest Payment Date shall be paid to the Person in whose name such Note
(or one or more Predecessor Notes) is registered at the close of business on the
Regular Record Date for such


                                      -45-








interest at the office or agency of the Company maintained for such purpose
pursuant to Section 10.02; 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 3.08, to the address of such Person as it appears in the Note Register
or (ii) transfer to an account located in the United States maintained by the
payee.

          Any interest on any Note 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 Notes (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 Notes (or their respective Predecessor Notes) 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 Note 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 to the Holders in the manner provided for in Section 1.06,
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


                                      -46-








shall be paid to the Persons in whose names the Notes (or their respective
Predecessor Notes) 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 Notes 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 3.07, each Note
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Note shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Note.

          SECTION 3.08. Persons Deemed Owners. Prior to the due presentment of a
Note for registration of transfer, the Company, the Trustee and any agent of the
Company or the Trustee may treat the Person in whose name such Note is
registered as the owner of such Note for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Sections 3.05 and 3.07)
interest on such Note and for all other purposes whatsoever, whether or not such
Note 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 3.09. Cancelation. All Notes 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
canceled by it. The Company may at any time deliver to the Trustee for
cancellation any Notes 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 Notes previously authenticated hereunder which the Company has not issued
and sold, and all Notes so delivered shall be promptly canceled by the Trustee.
If the Company shall so acquire any of the Notes, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Notes unless and until the same are surrendered to the
Trustee for cancellation. No Notes shall be authenticated in lieu of or


                                      -47-








in exchange for any Notes canceled as provided in this Section 3.09, except as
expressly permitted by this Indenture. All canceled Notes 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 canceled Notes be returned to it.

          SECTION 3.10. Computation of Interest. Interest on the Notes shall be
computed on the basis of a 360-day year of twelve 30-day months.

          SECTION 3.11. CUSIP Number. The Company, in issuing the Notes may use
a "CUSIP" number, and if so, such CUSIP number shall be included in notices of
redemption or exchange as a convenience to Holders; provided that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number printed in the notice or on the Notes, and that
reliance may be placed only on the other identification numbers printed on the
Notes. The Company will promptly notify the Trustee of any such CUSIP number
used by the Company in connection with the issuance of the Securities and of any
change in the CUSIP number.

                                   ARTICLE IV

                           Satisfaction and Discharge

          SECTION 4.01. Satisfaction and Discharge of Indenture. This Indenture
shall upon Company Request cease to be of further effect (except as to surviving
rights of registration of transfer or exchange of Notes expressly provided for
herein or pursuant hereto) and the Trustee, at the expense of the Company, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture when

          (1) either

               (a) all Notes theretofore authenticated and delivered (other than
          (i) Notes which have been destroyed, lost or stolen and which have
          been replaced or paid as provided in Section 3.06 and (ii) Notes for
          whose payment money has theretofore been deposited in trust with the
          Trustee or any 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


                                      -48-








          Section 10.03) have been delivered to the Trustee for cancellation; or

               (b) all Notes not theretofore delivered to the Trustee for
          cancelation

                    (i) have become due and payable,

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

                    (iii) are to be called for redemption within 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 Notes not theretofore
          delivered to the Trustee for cancelation, for the aggregate principal
          amount of, premium, if any, and interest on the Notes to the date of
          such deposit (in the case of Notes 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
     under this Indenture, the Notes and the Collateral Documents 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
     provided in this Indenture 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 6.06 and, if money shall
have been deposited with the Trustee pursuant to subclause (ii) of clause (1) of
this Section 4.01, the obligations of the Trustee under Section 4.02 and the
last paragraph of Section 10.03 shall survive.

          SECTION 4.02. Application of Trust Money. Subject to the provisions of
the last paragraph of


                                      -49-








Section 10.03, all money deposited with the Trustee pursuant to Section 4.01
shall be held in trust and applied by it, in accordance with the provisions of
the Notes 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 aggregate
principal amount of, 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.

                                    ARTICLE V

declare the principal amount of, premium, if any, and accrued interest on all of
the Outstanding Notes immediately due and payable, and upon any such declaration
all such amounts payable in respect of the Notes shall become immediately due

on all of the Outstanding Notes shall ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee or

          Outstanding Notes that have become due otherwise than by such
          declaration of acceleration and interest thereon at the rate borne by
          the Notes,

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

               (iv) all sums paid or advanced by the Trustee under this
          Indenture and the reasonable compensation, expenses, disbursements and
          advances of the Trustee, its agents and counsel; and

          (b) all Events of Default, other than the non- payment of amounts of
     principal of, premium, if any, or interest on the Notes that have become
     due solely by such declaration of acceleration, have been cured or waived
     as provided in Section 5.13.

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

          Notwithstanding the preceding paragraph, in the event of a declaration
of acceleration in respect of the Notes because of an Event of Default specified
in Section 5.01(5) shall have occurred and be continuing, such declaration of
acceleration shall be automatically annulled if the Indebtedness that is the
subject of such Event of Default has been discharged or the Holders thereof have
rescinded their declaration of acceleration in respect of such Indebtedness, and
written notice of such discharge or rescission, as the case may be, shall have
been given to the Trustee by the Company and countersigned by the holders of
such Indebtedness or a trustee, fiduciary or agent for such holders, within 30
days after such declaration of


                                      -53-








acceleration in respect of the Notes, and no other Event of Default has occurred
during such 30-day period which has not been cured or waived during such period.

          SECTION 5.03. 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 Note 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 Note at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to the Trustee for the benefit
of the Holders of such Notes, the whole amount then due and payable on such
Notes 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 Notes, 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 proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon the Notes or against the
Collateral 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 Notes, 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.


                                      -54-








          SECTION 5.04. 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 Notes or the
property of the Company or of such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Notes 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 Notes 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) to 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 6.06.

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

          SECTION 5.05. Trustee May Enforce Claims Without Possession of Notes.
All rights of action and claims under this Indenture or the Notes may be
prosecuted and enforced by the Trustee without the possession of any of the
Notes or


                                      -55-








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 Notes in respect of which such judgment has been recovered.

          SECTION 5.06. Application of Money Collected. Any money collected by
the Trustee pursuant to this Article V 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 Notes 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
     6.06;

          SECOND: To the payment of the amounts then due and unpaid for
     principal of (and premium, if any) and interest on the Notes 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 Notes for principal (and premium, if any) and interest,
     respectively; and

          THIRD: The balance, if any, to the Person or Persons entitled thereto.

          The Trustee may fix a record date and a payment date for any payments
to be made to Holders pursuant to this Section 5.06. At least 15 days before
such record date, the Company shall direct the Trustee to mail to each Holder a
notice that states the record date, the payment date and the amount to be paid.

          SECTION 5.07. Limitation on Suits. No Holder of any Notes 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;


                                      -56-








          (2) the Holders of not less than 25% in principal amount of the
     Outstanding Notes 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 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 Notes;

it being understood and intended 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 5.08. Unconditional Right of Holders to Receive Principal,
Premium and Interest. Notwithstanding any other provision in this Indenture, the
Holder of any Note shall have the right, which is absolute and unconditional, to
receive payment, as provided herein (including, if applicable, Article XIII) and
in such Note of the principal of (and premium, if any) and (subject to Section
3.07) interest on such Note on the respective Stated Maturities expressed in
such Note (or, in the case of redemption, on the Redemption Date) and to
institute suit for the enforcement of any such payment, and such rights shall
not be impaired without the consent of such Holder.

          SECTION 5.09. 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


                                      -57-








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 5.10. Rights and Remedies Cumulative. Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Notes in the last paragraph of Section 3.06, 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 5.11. Delay or Omission Not Waiver. No delay or omission of
the Trustee or of any Holder of any Note 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 V 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 5.12. Control by Holders. The Holders of not less than a
majority in principal amount of the Outstanding Notes shall have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee, provided that

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

          (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.


                                      -58-








          SECTION 5.13. Waiver of Past Defaults. The Holders of not less than a
majority in principal amount of the Outstanding Notes may, on behalf of the
Holders of all the Notes, waive any past defaults under this Indenture and their
consequences, except a default

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

          (2) in respect of a covenant or provision hereof which under Article
     IX cannot be modified or amended without the consent of the Holder of each
     Outstanding Note 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 5.14. 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.

                                   ARTICLE VI

                                   The Trustee

          SECTION 6.01. Notice of Defaults. (a) Within 30 days after the Trustee
receives notice of the occurrence of any Default or an Event of 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 or Event of 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 Note, the Trustee shall be
protected in withholding such notice if


                                      -59-








and so long as the Board of Directors, the executive committee or 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 5.01(4) no such notice to Holders shall be given until at
least 30 days after the occurrence thereof.

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

          (2) in the absence of bad faith on its part or manifest error, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture. However, in the case of any such certificates or opinion
     which by any provisions hereof are specifically required to be furnished to
     the Trustee, the Trustee shall examine such certificates and opinions to
     determine whether or not they conform to the requirements of this Indenture
     (but need not confirm or investigate the accuracy of mathematical
     calculations or other facts stated therein).

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

          (1) this paragraph does not limit the effect of paragraph (b) of this
     Section;

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

          (3) the Trustee shall not be liable with respect to any action it
     takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.5.

          (d) Every provision of this Indenture that in any way relates to the
Trustee is subject to paragraphs (b) and (c) of this Section.


                                      -60-








          (e) The Trustee shall not be liable for interest on any money received
by it except as the Trustee may agree in writing with the Company.

          (f) Money held in trust by the Trustee need not be segregated from
other funds except to the extent required by law.

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

          (h) 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 unless such Holders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses (including
reasonable attorneys' fees and expenses) and liabilities that might be incurred
by it in compliance with such request or direction.

          (i) The Trustee shall not be charged with knowledge of any Default or
Event of Default, of the identity of any Restricted Subsidiary or the existence
of any Change of Control or Asset Sale unless either (i) a Trust Officer shall
have actual knowledge thereof or (ii) the Trustee shall have received written
notice thereof from the Company or any Holder.

          SECTION 6.02. 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 shall be
     sufficiently evidenced by a Company Request or Company Order 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


                                      -61-








     matter be proved or established prior to taking, suffering or omitting any
     action hereunder, the Trustee (unless other evidence be herein specifically
     prescribed) may, in the absence of bad faith on its part, rely upon an
     Officers' Certificate or Opinion of Counsel and shall not be liable for any
     action it takes or omits to take in reliance in good faith on such
     Officers' Certificate or Opinion of Counsel;

          (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 or the other Collateral
     Documents at the request or direction of any of the Holders pursuant to
     this Indenture or the other Collateral Documents, unless such Holders shall
     have offered to the Trustee security or indemnity against the costs,
     expenses and liabilities which might be incurred by it in compliance with
     such request or direction reasonably satisfactory to the Trustee;

          (6) 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;

          (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


                                      -62-








     discretion or rights or powers conferred upon it by this Indenture; and

          (9) the permissive right of the Trustee to act hereunder will not be
     construed as a duty.

          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.

          SECTION 6.03. Trustee Not Responsible for Preamble or Issuance of
Notes. The preamble contained herein and in the Notes, 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 Notes, except that the Trustee represents that it is duly authorized to
execute and deliver this Indenture, authenticate the Notes and perform its
obligations hereunder and that the statements made by it in a Statement of
Eligibility on Form T-1 supplied to the Company are true and accurate, subject
to the qualifications set forth therein. The Trustee shall not be accountable
for the use or application by the Company of Notes or the proceeds thereof.

          SECTION 6.04. May Hold Notes. The Trustee, any Paying Agent, any Note
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 Notes and, subject to
TIA Sections 3.10(b) and 3.11, may otherwise deal with the Company with the same
rights it would have if it were not Trustee, Paying Agent, Note Registrar or
such other agent.

          SECTION 6.05. Money Held in Trust. Money held by the Trustee in trust
hereunder 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

                                      -63-








          SECTION 6.06. Compensation and Reimbursement. The Company agrees:

          (1) to pay to the Trustee from time to time reasonable compensation
     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);

          (2) except as otherwise expressly provided herein, 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 gross negligence or
     bad faith; and

          (3) to indemnify the Trustee for, and to hold it harmless against, any
     loss, liability or expense incurred without gross 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 of 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 6.06 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 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 Notes 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 Notes.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 5.01(7) or (8), 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 Bankruptcy Law.

          The provisions of this Section 6.06 shall survive the termination of
this Indenture.


                                      -64-








          SECTION 6.07. 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 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 Federal, State, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 6.07, 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 6.07, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article VI.

          SECTION 6.08. Resignation and Removal; Appointment of Successor.
(a) No resignation or removal of the Trustee and no appointment of a successor

of appointment by the successor Trustee in accordance with the applicable
requirements of Section 6.09.

          (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 6.09 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 Notes, 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 Note for at least six months,
     or

          (2) the Trustee shall cease to be eligible under Section 6.07 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 Note for at least six
     months, or


                                      -65-








          (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,

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 Note 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 Notes 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 Note for at least six months may, on behalf of himself and all
others similarly situated, 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
Notes in the manner provided for in Section 1.06. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

          SECTION 6.09. 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


                                      -66-








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.

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

          SECTION 6.10. 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 VI, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Notes 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 Notes so authenticated with the same effect
as if such successor Trustee had itself authenticated such Notes. In case at
that time any of the Notes shall not have been authenticated, any successor
Trustee may authenticate such Notes 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 Notes in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.


                                      -67-

          SECTION 8.01. Company May Consolidate, Etc., Only on Certain Terms.
The Company will not in a single transaction or a series of related transactions
consolidate with or merge with or into any other Person or sell, assign, convey,
transfer, lease or otherwise dispose of all or substantially all of its
properties and assets as an entirety to any Person or Persons, and the Company
will not permit any Restricted Subsidiary to enter into any such transaction, or
series of transactions, if such transaction or series of transactions, in the
aggregate, would result in the sale, assignment, conveyance, transfer, lease or
other disposition of all or substantially all of the properties and assets of
the Company and its Restricted Subsidiaries on a consolidated basis to any
Person or Persons, unless:

          (i) either

               (a) the Company shall be the surviving corporation or

               (b) the Person (if other than the Company) formed by such
          consolidation or into which the Company or the Company and its
          Restricted Subsidiaries is merged or the Person which acquires by
          sale, conveyance, transfer, lease or other disposition, all or
          substantially all of the properties and assets of the Company or the

          "Surviving Entity")


                                      -69-








                    (1) shall be a corporation organized and validly existing
               under the laws of the United States of America, any state thereof
               or the District of Columbia and

               this Indenture executed and delivered to the Trustee, in form
               satisfactory to the Trustee, the Company's obligations for the
               due and punctual payment of the principal of (or premium, if any,
               on) and interest on all the Notes and the performance and
               observance of every covenant of this Indenture on the part of the
               Company to be performed or observed;

          (ii) immediately after giving effect to such transaction or series of
     transactions on a pro forma basis (and treating any obligation of the
     Company or any Restricted Subsidiary in connection with or as a result of
     such transaction as having been incurred of the time of such transaction),
     no Default or Event of Default shall have occurred and be continuing;

          (iii) immediately after giving effect to such transaction or series of
     transactions on a pro forma basis (on the assumption that the transaction
     or series of transactions occurred on the first day of the latest four
     fiscal quarters for which consolidated financial statements of the Company
     are available prior to the consummation of such transaction or series of
     transactions with the appropriate adjustments with respect to the
     transaction or series of transactions, including the incurrence and
     repayment of any Indebtedness incident to such transaction, being included
     in such pro forma calculation), the Company (or the Surviving Entity if the
     Company is not the continuing obligor under this Indenture) could incur at
     least $1.00 of additional Indebtedness (other than Permitted Indebtedness)
     under the proviso to Section 10.11; provided, however, that this clause
     (iii) shall not apply to a consolidation, merger or sale, assignment,
     conveyance, transfer, lease or other disposition of all or substantially
     all of the properties and assets of the Company and its Restricted
     Subsidiaries if

               (a) all Liens and Indebtedness of the Company or the Surviving
          Entity, as the case may be, and its Restricted Subsidiaries
          outstanding


                                      -70-








          immediately after such transaction would, if incurred at such time,
          have been permitted to be incurred (and all such Liens and
          Indebtedness, other than the Liens and Indebtedness of the Company and
          its Restricted Subsidiaries outstanding immediately prior to the
          transaction, shall be deemed to have been incurred at such time) for
          all purposes of this Indenture and

               (b) immediately after giving effect to such transaction or series
          of transactions on a pro forma basis (and treating any obligation of
          the Company or any Restricted Subsidiary incurred in connection with
          or as a result of such transaction or series of transactions as having
          been incurred at the time of such transaction), the Consolidated Net
          Worth of the Company (or of the Surviving Entity if the Company is not
          the continuing obligor under this Indenture) is equal to or greater
          than the Consolidated Net Worth of the Company immediately prior to
          such transaction or series of transactions;

          (iv) if any of the property or assets of the Company or any of its
     Restricted Subsidiaries would thereupon become subject to any Lien, the
     provisions of Section 10.15 are complied with; and

          (v) the Company or the Surviving Entity shall have delivered to the
     Trustee an Officers' Certificate and an Opinion of Counsel, each stating
     that such consolidation, merger, sale, assignment, conveyance, transfer,
     lease or other disposition and such supplemental indenture comply with this
     Article VIII and that all conditions precedent herein provided for relating
     to such transaction have been complied with.

          SECTION 8.02. Successor Substituted. Upon any consolidation of the
Company with or merger of the Company with or into any other corporation or any
conveyance, transfer or lease of the properties and assets of the Company
substantially as an entirety to any Person in accordance with Section 8.01, the
successor Person formed by such consolidation or into which the Company is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Company
under this Indenture with the same effect as if such successor Person had been
named


                                      -71-








as the Company herein, and in the event of any such conveyance or transfer, the
Company (which term shall for this purpose mean the Person named as the
"Company" in the first paragraph of this Indenture or any successor Person which
shall theretofore become such in the manner described in Section 8.01), except
in the case of a lease, shall be discharged of all obligations and covenants
under this Indenture and the Notes and may be dissolved and liquidated.

          SECTION 8.03. Notes To Be Secured in Certain Events. If, upon any such
consolidation of the Company with or merger of the Company into any other
corporation, or upon any conveyance, lease or transfer of the property of the
Company substantially as an entirety to any other Person, any property or assets
of the Company would thereupon become subject to any Lien, then unless such Lien
could be created pursuant to Section 10.15 without equally and ratably securing
the Notes, the Company, prior to or simultaneously with such consolidation,
merger, conveyance, lease or transfer, will as to such property or assets,
secure the Notes Outstanding (together with, if the Company shall so determine,
any other Indebtedness of the Company now existing or hereinafter created which
is not subordinate in right of payment to the Notes) equally and ratably with
(or prior to) the Indebtedness which upon such consolidation, merger,
conveyance, lease or transfer is to become secured as to such property or assets
by such Lien, or will cause such Notes to be so secured; provided that, for the
purpose of providing such equal and ratable security, the principal amount of
the Notes shall mean that amount which would at the time of making such
effective provision be due and payable pursuant to Section 5.02 upon a
declaration of acceleration of the Maturity thereof, and the extent of such
equal and ratable security shall be adjusted, to the extent permitted by law, as
and when said amount changes over time as provided in Section 5.02.

                                   ARTICLE IX

                             Supplemental Indentures

     Notes in accordance with Section 8.01;

          (2) to add to the covenants of the Company or any obligor upon the
     Notes for the benefit of the Holders or to surrender any right or power
     herein conferred upon the Company or any other obligor upon the Notes for
     the benefit of the Holders, as applicable, in this Indenture or in the
     Notes;

          (3) to add any additional Events of Default;

          (4) to evidence and provide for the acceptance of appointment
     hereunder by a successor Trustee pursuant to the requirements of Section
     6.09;

          (5) to cure any ambiguity, to correct or supplement any provision
     herein or in the Collateral Documents or the Notes which may be
     inconsistent with any other provision herein or in the Collateral Documents
     or the Notes, or to make any other provisions with respect to matters or
     questions arising under this Indenture or the Notes; provided that such
     action shall not adversely affect the interests of the Holders in any
     material respect;

          (6) to secure the Notes pursuant to the requirements of Section 8.03
     or otherwise;

          (7) to comply with the requirements of the Commission in order to

     Indenture Act;

          (8) to add a guarantor of the securities under this Indenture;

          (9) to mortgage, pledge, hypothecate or grant a security interest in
     favor of the Trustee for the benefit of the Holders as additional security
     for the payment and performance of the Company's obligations under this
     Indenture, in any property, or assets, including any of which are required
     to be mortgaged, pledged or hypothecated, or in which a security


                                      -73-








     interest is required to be granted to the Trustee pursuant to this
     Indenture or otherwise; or

          (10) to convey, transfer, assign, mortgage or pledge to the Trustee or
     the Custodian Agent as security for the Notes and the other Secured Debt
     any property or assets.

          The Trustee is hereby authorized to join in the execution of any such
supplemental indenture, to make any further appropriate agreements and
stipulations which may be therein contained and to accept the conveyance,
transfer, assignment, mortgage or pledge of any property thereunder, but the
Trustee shall not be obligated to enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

          SECTION 9.02. Supplemental Indentures with Consent of Holders. With
the consent of the Holders of not less than a majority in principal amount of
the Outstanding Notes, by Act of said Holders delivered to the Company and the

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

accepting the additional trusts created by, any supplemental indenture permitted
by this Article IX or the modifications thereby of the trusts created by this

Indenture or otherwise.

          SECTION 9.04. Effect of Supplemental Indentures. Upon the execution of

supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee in exchange for Outstanding Notes.

          SECTION 9.07. Notice of Supplemental Indentures. Promptly after the
execution by the Company and the Trustee of any supplemental indenture pursuant

                                    ARTICLE X

                                    Covenants

          SECTION 10.01. 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 the principal of (and premium, if any) and interest on
the Notes in accordance with the terms of the Notes and this Indenture.

          SECTION 10.02. Maintenance of Office or Agency. The Company will
maintain in The City of New York, an office or agency where Notes may be
presented or surrendered for payment, where Notes may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Notes and this Indenture may be served. The
Corporate Trust Office of the Trustee 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


                                      -76-








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 Notes 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 10.03. Money for Note 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 of the
Notes, 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
Notes, it will, on or before each due date of the principal of (or premium, if
any) or interest on any Notes, 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


                                      -77-








Trustee, subject to the provisions of this Section 10.03, 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 Notes 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 Notes) 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.

          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.

          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 Note and remaining unclaimed for two years after such
principal, premium or interest has become due and payable shall 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 Note 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


                                      -78-








the date of such publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

          SECTION 10.04. Corporate Existence. Subject to Article VIII, 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 Restricted
Subsidiaries as a whole and that the loss thereof is not disadvantageous in any
material respect to the Holders.

          SECTION 10.05. 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 taxes, assessments and governmental charges levied or
imposed upon the Company or any Restricted Subsidiary or upon the income,
profits or property of the Company or any Restricted Subsidiary and (b) all
lawful claims for labor, materials and supplies, which, if unpaid, might by law
become a lien upon the property of the Company or any Restricted 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 whose
amount, applicability or validity is being contested in good faith by
appropriate proceedings.

          SECTION 10.06. Maintenance of Properties. The Company will cause all
properties owned by the Company or any Restricted Subsidiary or used or held for
use in the conduct of its business or the business of any Restricted Subsidiary
to be maintained and kept in good condition, repair and working order and
supplied with all necessary equipment and will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Company may be necessary so that the business carried on in
connection therewith may be properly conducted at all times; provided, however,
that nothing in this Section 10.06 shall prevent the Company from discontinuing
the maintenance of any of such properties if such discontinuance is, in the
judgment of the Company, desirable in the conduct of its business or the
business of any Subsidiary and not disadvantageous in any material respect
to the Holders.


                                      -79-








          SECTION 10.07. Insurance. (a) The Company shall maintain launch
insurance with respect to each satellite launch covering the period from the
launch to 180 days following the launch of each satellite in an amount equal to
or greater than the sum of (i) the cost to replace such satellite with a
satellite of comparable or superior technological capability (as determined by
the Board of Directors, whose determination shall be conclusive and evidenced by
a Board Resolution) and having at least as much transmission capacity as the
satellite to be replaced, (ii) the cost to launch a replacement satellite
pursuant to the contract whereby a replacement satellite will be launched and
(iii) the cost of launch insurance for such replacement or, in the event that
the Company has reason to believe that the cost of obtaining comparable
insurance for a replacement would be materially higher, the Company's best
estimate of the cost of such comparable insurance. Notwithstanding the
foregoing, the Company shall not be obligated to maintain insurance pursuant to
this paragraph (a) with respect to (i) the launch of its first satellite and
(ii) any subsequent launch not preceded by a launch failure or failure of any
satellite within 180 days from the date of its launch; provided, however, that
the Company's spare satellite shall be under construction in accordance with the
terms of the Loral Satellite Contract or the Company shall have otherwise
obtained a spare satellite.

          (b) The Company shall maintain full in-orbit insurance with respect to
each satellite it or a Restricted Subsidiary owns and launches in an amount at
least equal to (i) the cost to replace such satellite with a satellite of
comparable or superior technological capability (as determined by the Board of
Directors, whose determination shall be conclusive and evidenced by a Board
Resolution) and having at least as much transmission capacity as the satellite
to be replaced, (ii) the cost to launch a replacement satellite pursuant to the
contract pursuant to which a replacement satellite will be launched and (iii)
the cost of launch insurance for such replacement or, in the event that the
Company has reason to believe that the cost of obtaining comparable insurance
for a replacement would be materially higher, the Company's best estimate of the
cost of such comparable insurance. The in-orbit insurance required by this
paragraph shall provide that if 50% or more of a satellite's capacity is lost,
the full amount of insurance shall become due and payable, and that if a
satellite is able to maintain more than 50% but less that 100% of its capacity,
a portion of such insurance will become due and payable.


                                      -80-








          (c) In the event that the Company receives proceeds from insurance
relating to any satellite, the Company is entitled to use all or a portion of
such proceeds to repay any vendor or third-party purchase money financing
pertaining to such satellite that is required to be repaid by reason of the loss
giving rise to such insurance proceeds. The Company shall use the remainder of
such proceeds to develop and construct a replacement satellite; provided that
(i) such replacement satellite is of comparable or superior technological
capability as compared with the satellite being replaced and has at least as
much transmission capacity as the satellite being replaced (as determined by the
Board of Directors, whose determination shall be conclusive and evidenced by a
Board Resolution); (ii) the Company will have sufficient funds (together with
the proceeds of any business interruption insurance) to service the Company's
projected debt service requirements until the scheduled launch of the Company's
spare satellite and for one year thereafter and to develop and construct such
replacement satellite; and (iii) that the Company's spare satellite is scheduled
to be launched within 12 months of the receipt of such proceeds. Any such
proceeds not used as permitted by this paragraph shall constitute "Excess
Proceeds" for purposes of Section 10.16.

          SECTION 10.08. Statement by Officers as to Default. (a) The Company
shall deliver to the Trustee, within 60 days after the end of each fiscal
quarter (90 days after the end of the last fiscal quarter 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 10.08(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 an aggregate principal amount of less than $1,000,000), 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.


                                      -81-








          SECTION 10.09. Provision of Financial Statements and Reports. (a) The
Company shall file on a timely basis with the Commission, to the extent such
filings are accepted by the Commission and whether or not the Company has a
class of securities registered under the Exchange Act, the annual reports,
quarterly reports and other documents that the Company would be required to file
if it were subject to Section 13 or 15 of the Exchange Act.

          (b) The Company shall also (i) file with the Trustee, and provide to
each holder of Notes, without cost to such holder, copies of such reports and
documents within 15 days after the date on which the Company files such reports
and documents with the Commission or the date on which the Company would be
required to file such reports and documents if the Company were so required and
(ii) if the filing of such reports and documents with the Commission is not
accepted by the Commission or is prohibited under the Exchange Act, to supply at
the Company's cost copies of such reports and documents to any prospective
holder of Notes promptly upon written request.

          SECTION 10.10. Purchase of Notes upon Change in Control. (a) If a
Change of Control shall occur at any time, then each Holder shall have the right
to require that the Company purchase such Holder's Notes in whole or in part in
integral multiples of $1,000 principal amount, at a purchase price (the "Change
of Control Purchase Price") in cash in an amount equal to 101% of the principal
amount of such Notes as of the date of purchase plus accrued and unpaid
interest, if any, to the date of purchase (the "Change of Control Purchase
Date"), pursuant to the offer described below (the "Change of Control Offer"),
in accordance with the procedures set forth in paragraphs (b) and (c) of this
Section 10.10.

          (b) Within 15 days following any Change of Control, the Company shall
notify the Trustee thereof and give to each Holder of the Notes in the manner
provided in Section 1.06 a notice stating:

          (1) that a Change in Control has occurred and that such Holder has the
     right to require the Company to repurchase such Holder's Notes at the
     Change of Control Purchase Price;

          (2) the circumstances and relevant facts regarding such Change in
     Control (including but not limited to information with respect to pro forma
     historical


                                      -82-








     income, cash flow and capitalization after giving effect to such Change in
     Control);

          (3) the Change of Control Purchase Price and the Change of Control
     Purchase Date which shall be a Business Day no earlier than 30 days nor
     later than 60 days from the date such notice is mailed or such later date
     as is necessary to comply with requirements under the Exchange Act or any
     applicable securities laws or regulations;

          (4) that any Notes not tendered will continue to accrue interest;

          (5) that, unless the Company defaults in the payment of the Change of
     Control Purchase Price, any Notes accepted for payment pursuant to the
     Change of Control Offer shall cease to accrue interest after the Change of
     Control Purchase Date; and

          (6) the instructions a Holder must follow in order to have its Notes
     repurchased in accordance with paragraph (b) of this Section 10.10.

          The Company shall have no obligation to purchase any Notes in a Change
of Control Offer if no Notes are tendered by the Holders thereof.

          (c) Holders electing to have Notes purchased will be required to
surrender such Notes to the Company at the address specified in the notice at
least five Business Days prior to the Change of Control Purchase Date. Holders
will be entitled to withdraw their election if the Company receives, not later
than three Business Days prior to the Change of Control Purchase Date, a
telegram, telex, facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Notes delivered for purchase by the Holder
as to which his election is to be withdrawn and a statement that such Holder is
withdrawing his election to have such Notes purchased. Holders whose Notes are
purchased only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered.

          SECTION 10.11. Limitation on Indebtedness. The Company shall not, and
shall not permit any Restricted Subsidiary to, create, assume, issue, guarantee
or in any manner become directly or indirectly liable for or with respect to the
payment of, or otherwise incur (collectively, to "incur"), any Indebtedness,
except for Permitted


                                      -83-








Indebtedness; provided, however, that (i) the Company shall be permitted to
incur Indebtedness and (ii) a Restricted Subsidiary shall be permitted to incur
Acquired Indebtedness, if, in either case, after giving pro forma effect to such
incurrence (including the application of the net proceeds therefrom), the ratio
of (x) Total Consolidated Indebtedness to (y) Adjusted Consolidated Operating
Cash Flow for the latest four fiscal quarters for which consolidated financial
statements of the Company are available preceding the date of such incurrence,
taken as a whole, would be greater than zero and less than or equal to 4.0 to
1.0.

          SECTION 10.12. Limitation on Restricted Payments. (a) The Company
shall not make, and shall not permit any Restricted Subsidiary to make, directly
or indirectly, any of the following: (i) the declaration or payment of any
dividend or any other distribution on Capital Stock of the Company or any
payment made to the direct or indirect holders (in their capacities as such) of
Capital Stock of the Company (other than dividends or distributions payable
solely in Qualified Capital Stock of the Company or in options, warrants or
other rights to purchase Qualified Capital Stock of the Company); (ii) the
purchase, redemption or other acquisition or retirement for value of any Capital
Stock of the Company (other than any such Capital Stock owned by the Company or
a Restricted Subsidiary) or any affiliate of the Company (other than any
Restricted Subsidiary); (iii) the making of any principal payment on, or the
repurchase, redemption, defeasance or other acquisition or retirement for value
of, prior to any scheduled principal payment, sinking fund payment or maturity,
any Subordinated Indebtedness (other than any Subordinated Indebtedness held by
a Restricted Subsidiary); or (iv) the making of any Investment (other than a
Permitted Investment) in any Person (such payments or other actions described in
(but not excluded from) clauses (i) through (iv) are collectively referred to as
"Restricted Payments"), unless, in each case:

          (A) no Default or Event of Default shall have occurred and be
     continuing at the time of or after giving effect to such Restricted
     Payment;

          (B) immediately after giving effect to such Restricted Payment, the
     Company would be able to incur at least $1.00 of Indebtedness (other than
     Permitted Indebtedness) under the proviso of Section 10.11; and


                                      -84-








          (C) immediately after giving effect to such Restricted Payment, the
     aggregate amount of all Restricted Payments declared or made on or after
     November 26, 1997, would not exceed an amount equal to the sum of (a) the
     difference between (x) the Cumulative Available Cash Flow determined at the
     time of such Restricted Payment and (y) 150% of the cumulative Consolidated
     Interest Expense of the Company determined for the period commencing on
     November 26, 1997 and ending on the last day of the latest fiscal quarter
     for which consolidated financial statements of the Company are available
     preceding the date of such Restricted Payment plus (b) the aggregate Net
     Cash Proceeds received by the Company from the issue or sale (other than to
     any Restricted Subsidiary) of Qualified Capital Stock of the Company after
     January 1, 1998, plus (c) the aggregate Net Cash Proceeds received after
     November 26, 1997, by the Company from the issuance or sale (other than to
     any Restricted Subsidiary) of debt securities or Redeemable Capital Stock
     that have been converted into or exchanged for Qualified Capital Stock of
     the Company, together with the aggregate Net Cash Proceeds received by the
     Company at the time of such conversion or exchange, plus (d) to the extent
     not otherwise included in the Consolidated Operating Cash Flow of the
     Company, an amount equal to the sum of (1) the net reduction in Investments
     in any Person (other than the Permitted Investments) resulting from the
     payment in cash of dividends, repayments of loans or advances or other
     transfers of assets, in each case to the Company or any Restricted
     Subsidiary after November 26, 1997, from such Person and (2) the portion
     (proportionate to the Company's equity interest in such Subsidiary) of the
     fair market value of the net assets of any Unrestricted Subsidiary at the
     time such Unrestricted Subsidiary is designated a Restricted Subsidiary;
     provided, however, that in the case of (1) or (2) above the foregoing sum
     shall not exceed the aggregate amount of Investments previously made (and
     treated as a Restricted Payment) by the Company or any Restricted
     Subsidiary in such Person or Unrestricted Subsidiary, minus (e) the sum of
     80% of the outstanding principal amount of the Notes and all Indebtedness
     incurred pursuant to clause (a)(2) of the definition of Permitted
     Indebtedness.

For purposes of determining the amount expended for Restricted Payments,
property other than cash shall be valued at its Fair Market Value.


                                      -85-








          (b) The provisions of this Section 10.11(a) shall not prohibit, so
long as, with respect to clauses (ii) through (viii) below, no Default or Event
of Default shall have occurred and be continuing,

          (i) the payment of any dividend or other distribution within 60 days
     after the date of declaration thereof if at such date of declaration such
     payment complied with the provisions of this Indenture, and such payment
     will be deemed to have been paid on the date of declaration for purposes of
     the calculation in the foregoing paragraph;

          (ii) the purchase, redemption, retirement or other acquisition of any
     shares of Capital Stock of the Company in exchange for, or out of the Net
     Cash Proceeds of a substantially concurrent issue and sale (other than to a
     Restricted Subsidiary) of, shares of Qualified Capital Stock of the
     Company;

          (iii) the purchase, redemption, retirement, defeasance or other
     acquisition or retirement for value of Subordinated Indebtedness made by
     exchange for, or out of the Net Cash Proceeds of a substantially concurrent
     issue or sale (other than to a Restricted Subsidiary) of, Qualified Capital
     Stock of the Company;

          (iv) the purchase of (A) any Subordinated Indebtedness at a purchase
     price not greater than 101% of the principal amount or accreted value
     thereof, as the case may be, together with accrued interest, if any, in the
     event of a Change of Control in accordance with provisions similar to
     Section 10.10 or (B) any Preferred Stock at a purchase price not greater
     than 101% of the liquidation preference thereof, together with accrued
     dividends, if any, in the event of a Change of Control in accordance with
     provisions similar to Section 10.10; provided, however, that, in each case,
     prior to such purchase the Company has made the Change of Control Offer as
     provided in Section 10.10 with respect to the Notes and has purchased all
     Notes validly tendered for payment in connection with such Change of
     Control Offer;

          (v) the purchase, redemption, defeasance or other acquisition or
     retirement for value of Subordinated Indebtedness in exchange for, or out
     of the Net Cash Proceeds of a substantially concurrent incurrence (other
     than to a Restricted Subsidiary) of, new Subordinated Indebtedness so long
     as


                                      -86-








               (A) the principal amount of such new Subordinated Indebtedness
          does not exceed the principal amount (or, if such Subordinated
          Indebtedness being refinanced provides for an amount less than the
          principal amount thereof to be due and payable upon a declaration of
          acceleration thereof, such lesser amount as of the date of
          determination) of the Subordinated Indebtedness being so purchased,
          redeemed, defeased, acquired or retired, plus the lesser of the amount
          of any premium required to be paid in connection with such refinancing
          pursuant to the terms of the Subordinated Indebtedness being
          refinanced or the amount of any premium reasonably determined by the
          Company as necessary to accomplish such refinancing, plus, in either
          case, the amount of expenses of the Company incurred in connection
          with such refinancing,

               (B) such new Subordinated Indebtedness is subordinated to the
          Notes to the same extent as such Subordinated Indebtedness so
          purchased, redeemed, defeased, acquired or retired and

               (C) such new Subordinated Indebtedness has an Average Life longer
          than the Average Life of the Notes and a final Stated Maturity of
          principal later than the Stated Maturity of principal of the Notes;

          (vi) the purchase of any Subordinated Indebtedness at a purchase price
     not greater than 100% of the principal amount or accreted value thereof, as
     the case may be, together with accrued interest, if any, following an Asset
     Sale in accordance with provisions similar to Section 10.16; provided,
     however, that prior to making any such purchase the Company has made the
     Excess Proceeds Offer as provided in such covenant with respect to the
     Notes and has purchased all Notes validly tendered for payment in
     connection with such Excess Proceeds Offer; (vii) the payment of cash
     dividends on outstanding shares of Series C Preferred Stock of the Company
     out of the Net Cash Proceeds of a substantially concurrent issue and sale
     (other than to a Restricted Subsidiary) of Common Stock of the Company; and
     (viii) any other Restricted Payments in an aggregate amount not to exceed
     $15.0 million.

          In determining the amount of Restricted Payments permissible under
this covenant, amounts expended pursuant


                                      -87-








to clauses (i), (ii), (iii), (iv), (vi), (vii) and (viii) above shall be
included as Restricted Payments.

          SECTION 10.13. Limitation on Issuances and Sales of Capital Stock of
Restricted Subsidiaries. The Company (a) shall not permit any Restricted
Subsidiary to issue any Capital Stock (other than to the Company or a Restricted
Subsidiary) and (b) shall not permit any Person (other than the Company or a
Restricted Subsidiary) to own any Capital Stock of any Restricted Subsidiary;
provided, however, that this covenant shall not prohibit (i) the issuance and
sale of all, but not less than all, of the issued and outstanding Capital Stock
of any Restricted Subsidiary owned by the Company or any Restricted Subsidiary
in compliance with the other provisions of this Indenture or (ii) the ownership
by directors of directors' qualifying shares or the ownership by foreign
nationals of Capital Stock of any Restricted Subsidiary, to the extent mandated
by applicable law.

          SECTION 10.14. Limitation on Transactions with Affiliates. The Company
shall not, and shall not permit any Restricted Subsidiary to, directly or
indirectly, enter into or suffer to exist any transaction or series of related
transactions (including the sale, purchase, exchange or lease of assets,
property or services) with, or for the benefit of, any Affiliate of the Company
(other than the Company or a Restricted Subsidiary) unless (i) such transaction
or series of related transactions is on terms that are no less favorable to the
Company or such Restricted Subsidiary, as the case may be, as determined in good
faith by the Board of Directors, whose determination shall be conclusive and
evidenced by a Board Resolution, than those that could have been obtained in an
arm's-length transaction with unrelated third parties who are not Affiliates,
(ii) with respect to any transaction or series of related transactions involving
aggregate consideration equal to or greater than $2,500,000, the Company shall
have delivered an officers' certificate to the Trustee certifying that such
transaction or series of related transactions complies with clause (i) above and
such transaction or series of related transactions has been approved by a
majority of the Disinterested Directors of the Board of Directors of the
Company, or the Company has obtained a written opinion from a nationally
recognized investment banking firm to the effect that such transaction or series
of related transactions is fair to the Company or such Restricted Subsidiary, as
the case may be, from a financial point of view and (iii) with respect to any
transaction or series of related transactions including aggregate consideration
in excess of $10,000,000, or in the event no members of the


                                      -88-








Board of Directors of the Company are Disinterested Directors with respect to
any transaction or series of transactions included in clause (ii), the Company
shall obtain an opinion from a nationally recognized investment banking firm as
described above; provided, however, that this Section 10.14 will not restrict
(1) any transaction by the Company or any Restricted Subsidiary with an
Affiliate directly related to the purchase, sale or distribution of products in
the ordinary course of business consistent with industry practice, (2) the
Company from paying reasonable and customary regular compensation and fees to

(including stock options and other incentive compensation) to officers and other
employees the terms of which are approved by the Board of Directors, (4) the
Company or any Restricted Subsidiary from making any Restricted Payment in
compliance with Section 10.12 (including pursuant to paragraph (b) thereof), (5)

agreement in a manner materially adverse to the holders of the Notes, (6)
transactions among the Company and its Restricted Subsidiaries, (7) amendments
to the Loral Satellite Contract; provided, however, that the Company will not
amend, modify or in any way alter the terms of such agreement in a manner
materially adverse to the holders of the Notes.

          SECTION 10.15. Limitation on Liens. The Company shall not, and shall
not permit any Restricted Subsidiary to, directly or indirectly, create, incur,
assume or suffer to exist any Lien of any kind, other than Permitted Liens, on
or with respect to any of its property or assets, including any shares of stock
or indebtedness of any Restricted Subsidiary, whether owned at the date of this
Indenture or thereafter acquired, or any income, profits or proceeds therefrom,
or assign or otherwise convey any right to receive income thereon, unless (x) in
the case of any Lien securing Subordinated Indebtedness, the Notes are secured
by a Lien on such property, assets or proceeds that is senior in priority to
such Lien and (y) in the case of any other Lien, the Notes are equally and
ratably secured.

          SECTION 10.16. Limitation on Sale of Assets. (a) The Company shall
not, and shall not permit any Restricted Subsidiary to, directly or indirectly,
engage in


                                      -89-








any Asset Sale unless (i) the consideration received by the Company or such
Restricted Subsidiary for such Asset Sale is not less than the Fair Market Value
of the shares or assets sold (as determined by the Board of Directors, whose
determination shall be conclusive and evidenced by a Board Resolution) and (ii)
the consideration received by the Company or the relevant Restricted Subsidiary
in respect of such Asset Sale consists of at least 80% cash or Cash Equivalents.

          (b) If the Company or any Restricted Subsidiary engages in an Asset
Sale, the Company shall be entitled to use the Net Cash Proceeds thereof within
12 months after the later of such Asset Sale or the receipt of such Net Cash
Proceeds (i) to permanently repay or prepay any then outstanding Pari Passu
Indebtedness, (ii) to invest in any one or more businesses, capital expenditures
or other tangible assets of the Company or any Restricted Subsidiary, in each
case, engaged, used or useful in the CD Radio Business (or enter into a legally
binding agreement to do so within six months); or (iii) to invest in properties
or assets that replace the properties and assets that are the subject to such
Asset Sale (or enter into a legally binding agreement to do so within six
months). If any such legally binding agreement to invest such Net Cash Proceeds
is terminated, then the Company may, within 90 days of such termination or
within 12 months of such Asset Sale, whichever is later, apply or invest such
Net Cash Proceeds as provided in clause (i), (ii) or (iii) (without regard to
the parenthetical contained in clause (ii) or (iii)) above. The amount of such
Net Cash Proceeds not so used as set forth above in this paragraph (b)
constitutes "Excess Proceeds".

          (c) When the aggregate amount of Excess Proceeds exceeds $10,000,000
the Company shall (i) comply with the provisions of Section 1016(c) of the
Discount Notes Indenture that require the Company to make an offer to purchase
Discount Notes, if applicable, and (ii) within 30 business days after the
completion of such offer, or if such provisions are not applicable, within 30
days after the time Excess Proceeds exceed $10,000,000, make an offer to
purchase (an "Excess Proceeds Offer") from all holders of Notes and, if the
Company so elects, from Holders of Pari Passu Indebtedness, on a pro rata basis,
in accordance with the procedures set forth below, the maximum principal amount
(expressed as a multiple of $1,000) of Notes and, if applicable, such Pari Passu
Indebtedness that may be purchased with the Excess Proceeds. In the case of
other Pari Passu Indebtedness that is issued at a discount to its


                                      -90-








face amount, the requirement that Notes and other Pari Passu Indebtedness be
purchased on a "pro rata basis" means that the amount of such other Pari Passu
Indebtedness to be purchased will be based on the amount to which the Pari Passu
Indebtedness has accreted in value for purposes of determining the amount that
would be payable thereon in the event of the occurrence of an event of default
(or similar event) under such other Pari Passu Indebtedness. The offer price as
to each Note and such other Pari Passu Indebtedness shall be payable in cash in
an amount equal to 100% of the accreted value, as the case may be, of such Note
or other Pari Passu Indebtedness (without premium) as of the date of purchase
plus accrued interest, if any (the "Offered Price"), to the date such Excess
Proceeds Offer is consummated (the "Offer Date"). To the extent that the
aggregate principal amount, or accreted value, as the case may be, of Notes and
such other Pari Passu Indebtedness tendered pursuant to an Excess Proceeds Offer
is less than the Excess Proceeds relating thereto, the Company may use such
additional Excess Proceeds for general corporate purposes or to fund an offer to
redeem any outstanding Subordinated Indebtedness in accordance with provisions
similar to this Section 10.16. If the aggregate principal amount of Notes and
such other Pari Passu Indebtedness validly tendered and not withdrawn by holders
thereof exceeds the Excess Proceeds, Notes and such other Pari Passu
Indebtedness to be purchased will be selected on a pro rata basis. Upon
completion of such offer to purchase, the amount of Excess Proceeds shall be
reset to zero.

          (d) If the Company becomes obligated to make an Excess Proceeds Offer
pursuant to clause (c) above, the Notes shall be purchased by the Company, at
the option of the holder thereof, in whole or in part in integral multiples of
$1,000, on a date that is not earlier than 30 days and not later than 60 days
from the date the notice is given to holders, or such later date as may be
necessary for the Company to comply with the requirements under the Exchange Act
or any other applicable securities laws or regulations, subject to proration in
the event the amount of Excess Proceeds is less than the aggregate Offered Price
of all Notes and such other Pari Passu Indebtedness tendered.

          (e) The Company shall comply to the extent applicable with the
requirements of the tender offer rules, including Rule 14e-1 under the Exchange
Act, and any other applicable securities laws and regulations in connection with
an Excess Proceeds Offer.


                                      -91-








          SECTION 10.17. Limitation on Dividend and Other Payment Restrictions
Affecting Restricted Subsidiaries. The Company shall not, and shall not permit
any Restricted Subsidiary to, directly or indirectly, create or otherwise cause
or suffer to exist or become effective any encumbrance or restriction of any
kind on the ability of any Restricted Subsidiary to (a) pay dividends, in cash
or otherwise, or make any other distributions on or in respect of its Capital
Stock, (b) pay any Indebtedness owed to the Company or any other Restricted
Subsidiary, (c) make Investments in the Company or any other Restricted
Subsidiary, (d) transfer any of its properties or assets to the Company or any
other Restricted Subsidiary or (e) guarantee any Indebtedness of the Company or
any other Restricted Subsidiary, except for such encumbrances or restrictions
existing under or by reason of (i) any agreement in effect on the Issue Date,
(ii) applicable law or judicial or regulatory action, (iii) customary
nonassignment provisions of any lease governing a leasehold interest of the
Company or any Restricted Subsidiary, (iv) any agreement or other instrument of
a Person acquired by the Company or any Restricted Subsidiary in existence at
the time of such acquisition (but not created in contemplation thereof), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the
Person, so acquired and the Subsidiaries of such Person, (v) any mortgage or
other Lien on real property acquired or improved by the Company or any
Restricted Subsidiary after the date of this Indenture that prohibit transfers
of the type described in (d) above with respect to such real property, (vi) any
encumbrance or restriction contained in contracts for sales of assets permitted
by Section 10.16 with respect to the assets to be sold pursuant to such
contract; (vii) any such customary encumbrance or restriction contained in a
security document creating a Permitted Lien to the extent relating to the
property or asset subject to such Permitted Lien; (viii) any agreement or other
instrument governing any Pari Passu Indebtedness if such encumbrance or
restriction applies only (x) to amounts which at any point in time (other than
during such periods as are described in clause (y)) (1) exceed amounts due and
payable (or which are to become due and payable within 30 days) in respect of
the Notes or this Indenture for interest, premium and principal (after giving
effect to any realization by the Company under any applicable Currency
Agreement), or (2) if paid, would result in an event described in the following
clause (y) of this sentence, or (y) during the pendency of any event that
causes, permits or, after notice or lapse of time, would cause or permit the
holder(s) of the


                                      -92-








Indebtedness governed by such agreement or instrument to declare any such
Indebtedness to be immediately due and payable or require cash collateralization
or cash cover for such Indebtedness for so long as such cash collateralization
or cash cover has not been provided; or (ix) the refinancing of Indebtedness
incurred under the agreements described in clause (v) above, so long as such
encumbrances or restrictions are no less favorable in any material respect to
the Company or any Restricted Subsidiary than those contained in the respective
agreement as in effect on the Issue Date.

          SECTION 10.18. Waiver of Certain Covenants. The Company may omit in
any particular instance to comply with any term, provision or condition set
forth in Section 8.03, Sections 10.07 or 10.09 through 10.17, inclusive, if
before or after the time for such compliance the Holders of at least a majority
in principal amount of the Outstanding Notes, by Act of such Holders, waive such
compliance in such instance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

          SECTION 10.19. Required Stock Ownership. The Company will at all times
be the legal and beneficial owner of the Pledged Stock and will not sell,
transfer or otherwise dispose of any Capital Stock of Satellite CD Radio, Inc.

          SECTION 10.20. Further Assurances. The Company will promptly execute
and deliver such additional instruments and do such further acts as in the
opinion of the Trustee may be reasonably necessary or proper to carry out the
purposes of this Indenture and the Collateral Documents.

          SECTION 10.21. Limitation on Subsidiary Business Activities. Satellite
CD Radio, Inc., shall not engage in any trade or business other than holding an
FCC license to build, launch and operate a national satellite radio broadcast
system.

          SECTION 10.22. Limitation on Sale-Leaseback Transactions. The Company
will not, and will not permit any Restricted Subsidiary to, directly or
indirectly, enter into any sale-leaseback transaction involving any of its
assets


                                      -93-








or properties whether now owned or hereafter acquired, whereby the Company or a
Restricted Subsidiary sells or transfers such assets or properties and then or
thereafter leases such assets or properties or any part thereof or any other
assets or properties which the Company or such Restricted Subsidiary, as the
case may be, intends to use for substantially the same purpose or purposes as
the assets sold or transferred.

          The foregoing restriction does not apply to any sale-leaseback
transaction if (a) the lease is for a period, including renewal rights, of not
in excess of three years;(b) the transaction is solely between the Company and
any Restricted Subsidiary or solely between Restricted Subsidiaries; (c) the
Company or such Restricted Subsidiary, within 12 months after the sale or
transfer of any assets or properties is completed, applies an amount not less
than the net proceeds received from such sale in accordance with paragraph (b)
of Section 10.16.

          SECTION 10.23. Pledge Account. (a) Upon the closing of the offering of
the Securities by the Company, the Company shall purchase, and deposit in the
Pledge Account for the benefit of Holders and owners of beneficial ownership
interests in the Notes, Pledged Securities in an amount which, in the opinion of
an internationally recognized firm of independent public accountants expressed
in a written certification thereof delivered to the Trustee, will result in the
receipt of United States dollars in immediately available funds in amounts and
at times sufficient to provide for payment in full when due of the six regularly
scheduled interest payments due on the Notes from November 15, 1999 through May
15, 2002 upon receipt of scheduled principal and interest payments on the
Pledged Securities.

          (b) The Company hereby agrees that all of its rights and obligations
with respect to the Pledged Securities shall be as set forth in the Collateral
Pledge Agreement.

                                   ARTICLE XI

                               Redemption of Notes

          SECTION 11.01. Right of Redemption. The Notes may be redeemed, at the
election of the Company, as a whole or from time to time in part, at any time on
or after May 15, 2004, subject to the conditions and at the


                                      -94-








Redemption Prices specified in the form of Note, together with accrued interest
to the Redemption Date.

          In addition, at any time or from time to time prior to May 15, 2002,
the Company may redeem up to a maximum of 35% of the original aggregate
principal amount of the Notes with the net proceeds of one or more Equity
Offerings at a redemption price (expressed as a percentage of principal amount
on the redemption date) of 114.5% plus accrued interest to the redemption date;
provided, however, that immediately after giving effect to such redemption, at
least 65% of the original aggregate principal amount of the Notes remains
outstanding; provided further, however, that notice of such redemption shall be
given within 60 days of the closing of such Equity Offering.

          SECTION 11.02. Applicability of Article. Redemption of Notes 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 XI.

          SECTION 11.03. Election to Redeem; Notice to Trustee. The election of
the Company to redeem any Notes pursuant to Section 11.01 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 in writing of such Redemption Date and of the principal amount of
Notes to be redeemed and shall deliver to the Trustee such documentation and
records as shall enable the Trustee to select the Notes to be redeemed pursuant
to Section 11.04.

          SECTION 11.04. Selection by Trustee of Notes To Be Redeemed. If less
than all the Notes are to be redeemed, the particular Notes to be redeemed shall
be selected not more than 60 days prior to the Redemption Date by the Trustee by
such method as the Trustee shall deem fair and appropriate; provided, however,
that no such partial redemption shall reduce the portion of the principal amount
of a Note not redeemed to less than $1,000.

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


                                      -95-








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

          SECTION 11.05. Notice of Redemption. Notice of redemption shall be
given in the manner provided for in Section 1.06 not less than 30 nor more than
60 days prior to the Redemption Date, to each Holder of Notes to be redeemed.

          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 11.07, if any;

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

          (4) in case any Note is to be redeemed in part only, the notice which
     relates to such Note shall state that on and after the Redemption Date,
     upon surrender of such Note, the holder will receive, without charge, a new
     Note or Notes 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
     11.07) will become due and payable upon each such Note, or the portion
     thereof, to be redeemed, and that interest thereon will cease to accrue on
     and after said date; and

          (6) the name and address of the Paying Agent where such Notes are to
     be surrendered for payment of the Redemption Price and accrued interest, if
     any.

          (7) that Notes call for redemption must be surrendered to the Paying
     Agent to collect the Redemption Price,

          (8) the CUSIP number, and that no representation is made as to the
     accuracy or correctness of the CUSIP


                                      -96-








     number, if any, listed in such notice or printed on the Notes, and

          (9) the paragraph of the Notes pursuant to which the Notes are to be
     redeemed.

          Notice of redemption of Notes to be redeemed at the election of the
Company 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 11.06. Deposit of Redemption Price. Prior to 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 10.03) an amount of money sufficient to pay the Redemption
Price of, and accrued interest on, all the Notes which are to be redeemed on
that date.

          SECTION 11.07. Notes Payable on Redemption Date. Notice of redemption
having been given as aforesaid, the Notes 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 Notes shall cease to accrue
interest. Upon surrender of any such Note for redemption in accordance with said
notice, such Note 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 whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Notes, or one or more Predecessor
Notes, registered as such at the close of business on the relevant Record Dates
according to their terms and the provisions of Section 3.07.

          If any Note called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Notes.

          SECTION 11.08. Notes Redeemed in Part. Any Note which is to be
redeemed only in part (pursuant to the provisions of this Article XI) shall be
surrendered at the office or agency of the Company maintained for such purpose
pursuant to Section 10.02 (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company


                                      -97-








and the Trustee duly executed by, the Holder thereof or such Holders attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Note without service
charge, a new Note or Notes, 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 amount of the Note so surrendered.

                                   ARTICLE XII

                        Security and Pledge of Collateral

          SECTION 12.01. Collateral Documents. Each Holder of a Note, by its
acceptance thereof, (i) consents and agrees to the terms of the Collateral
Documents, (ii) authorizes and ratifies the entering into by the Trustee and the
Collateral Agent of each of the Collateral Documents to which they are a party
and (iii) authorizes and directs the Trustee and the Collateral Agent to perform
their respective obligations and exercise their rights thereunder in accordance
therewith.

          SECTION 12.02. Trustee May Perform. If the Company fails to perform
any agreement contained in this Article XII, the Trustee may, but shall not be
obligated to, itself perform, or cause performance of, such agreement, and the
expenses of the Trustee incurred in connection therewith shall be payable by the
Company under Section 6.06.

          SECTION 12.03. Collateral Trust Arrangements. (a) The Trustee shall,
upon request of the Company and upon receipt of the Opinion of Counsel and
Officer's Certificate described in paragraph (c) of this Section 12.03 (i)
amend, revise and supplement the Pledge Agreement to assign and pledge to the
Collateral Agent for the benefit of the Holders of the Notes the holders of the
Discount Notes and the equal and ratable benefit of the Secured Parties a
security interest in the Bond Collateral and (ii) enter into an amended
Intercreditor Agreement that provides for the enforcement of the payment of
Indebtedness under this Indenture equally and ratably with all other Secured
Debt.

          (b) Upon any such assignment or pledge pursuant to paragraph (a)
above, the Bond Collateral shall be held in trust under and subject to the terms
and conditions of the Collateral Documents and the amended Intercreditor
Agreement for the benefit of the Secured Parties and for the enforcement of the
payment of Indebtedness under this


                                      -98-








Indenture equally and ratably with all other Secured Debt and for the
performance of and compliance with the covenants and conditions of this
Indenture and the other Collateral Documents. It is intended that this Indenture
and the other Collateral Documents shall be construed and enforced to give
effect to such intention.

          (c) Prior to giving effect to any assignment or pledge of the Bond
Collateral to the Collateral Agent as set forth in Section 12.03(a), the Trustee
shall receive, and shall be fully protected in relying upon, an Opinion of
Counsel and an Officer's Certificate as to the validity and perfection of a
first-priority lien on the Bond Collateral for the equal and ratable benefit of
the Secured Parties.

          SECTION 12.04. Certificates and Opinions. The Company shall comply
with (a) TIAss.314(b), relating to Opinions of Counsel regarding the Lien of
this Indenture and (b) TIAss.314(d), relating to, among other matters, the
release of Bond Collateral from the Lien of this Indenture and Officers'
Certificates or other documents regarding fair value of the Bond Collateral, to
the extent such provisions are applicable. Any certificate or opinion required
by TIA ss.314(d) may be executed and delivered by an Officer of the Company to
the extent permitted by TIA'SS'314(d).

                                  ARTICLE XIII

                       Defeasance and Covenant Defeasance

          SECTION 13.01. 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 Notes, elect to have either Section 13.02 or Section 13.03
be applied to all Outstanding Notes upon compliance with the conditions set
forth below in this Article XIII.

          SECTION 13.02. Defeasance and Discharge. Upon the Company's exercise
under Section 13.01 of the option applicable to this Section 13.02, the Company
shall be deemed to have been discharged from its obligations with respect to all
Outstanding Notes on the date the conditions set forth in Section 13.04 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the Outstanding Notes, which shall thereafter be
deemed to be "Outstanding" only for the purposes of Section 13.05 and the other
Sections of this Indenture referred to in (A) and (B) below, and to have


                                      -99-








satisfied all its other obligations under such Notes, this Indenture and the
Collateral Pledge Agreement insofar as such Notes 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 Notes to receive, solely from the trust fund described in Section
13.04 and as more fully set forth in Section 13.04, payments in respect of the
principal of (and premium, if any, on) and interest on such Notes when such
payments are due, (B) the Company's obligations with respect to such Notes under
Sections 3.04, 3.05, 3.06, 10.02 and 10.03, (C) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (D) this Article XIII.
Subject to compliance with this Article XIII, the Company may exercise its
option at any time under this Section 13.02 notwithstanding the prior exercise
of its option under Section 13.03 with respect to the Notes.

          SECTION 13.03. Covenant Defeasance. Upon the Company's exercise under
Section 13.01 of the option applicable to this Section 13.03, the Company shall
be released from its obligations under any covenant contained in Section 8.03
and in Sections 10.07 through 10.17 with respect to the Outstanding Notes on and
after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance"), and the Notes 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 Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section
5.01(4), but, except as specified above, the remainder of this Indenture and
such Notes shall be unaffected thereby.

          SECTION 13.04. Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions


                                     -100-








to application of either Section 13.02 or Section 13.03 to the Outstanding
Notes:

          (1) The Company shall irrevocably have deposited or caused to be
     deposited with the Trustee (or another trustee satisfying the requirements
     of Section 6.07 who shall agree to comply with the provisions of this
     Article XIII 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 Notes, (A) money in
     an amount, 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, or a nationally recognized investment banking firm, 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 and discharge, at the principal of (and premium, if any)
     and interest on the Outstanding Notes at their Stated Maturity (or
     Redemption Date, if applicable) of such principal (and premium, if any) or
     installment of interest on the day on which such payments are due and
     payable in accordance with the terms of this Indenture and of such Notes;
     provided that the Trustee shall have been irrevocably instructed to apply

     payments with respect to the Notes. Before such a deposit, the Company may
     give to the Trustee, in accordance with Section 11.03 hereof, a notice of
     its election to redeem all of the Outstanding Notes at a future date in

     thereof, and shall also include a depository receipt issued by a bank (as
     defined in Section 3(a)(2) of the Securities Act), as custodian with
     respect to any such U.S. Government Obligation or a specific payment of
     principal of or interest on any such U.S. Government Obligation held by
     such custodian for the account of the holder of such depository receipt;
     provided that (except as required by law) such custodian is not authorized
     to make any deduction from the amount payable to the holder of such
     depository receipt from any amount received by the custodian in respect of
     the U.S. Government Obligation or the specific payment of principal of or
     interest on the U.S. Government Obligation evidenced by such depository
     receipt.

          (2) No Default or Event of Default with respect to the Notes shall
     have occurred and be continuing on the date of such deposit or, insofar as
     paragraphs (8) and (9) of Section 5.01 hereof are concerned, at any time

     being understood that this condition shall not be deemed satisfied until
     the expiration of such period).

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

          (4) In the case of an election under Section 13.02, 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 May 13, 1999, 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 Notes 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.

          (5) In the case of an election under Section 13.03, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Holders of the Outstanding Notes will not recognize income, gain or loss
     for federal income tax purposes as


                                     -102-








     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) In the case of an election under Section 13.02 or Section 13.03,

     deposit or after the date such opinion is delivered, the trust funds will

          (7) The Company shall have delivered to the Trustee an Officers'
     Certificate stating that the deposit was not made by the Company with the
     intent of preferring the holders of the Notes over the other creditors of
     the Company with the intent of hindering, delaying or defrauding creditors
     of the Company.

          (8) 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 defeasance under Section
     13.02 or the covenant defeasance under Section 13.03 (as the case may be)
     have been complied with.

          SECTION 13.05. 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 10.03, 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 13.05, the "Trustee")
pursuant to Section 13.04 in respect of the Outstanding Notes shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal (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


                                     -103-








to Section 13.04 or the principal and interest received in respect thereof other
than any such tax, fee or other charge which by law is for the account of the
Holders of the Outstanding Notes.

          Anything in this Article XIII 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 13.04 which, in the opinion of a nationally recognized firm of
independent public accountants, or a nationally recognized investment banking
firm, 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 an equivalent defeasance or covenant defeasance, as applicable, in
accordance with this Article XIII.

          SECTION 13.06. Reinstatement. If the Trustee or any Paying Agent is
unable to apply any money in accordance with Section 13.05 by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, then the Company's obligations under
this Indenture and the Notes shall be revived and reinstated as though no
deposit had occurred pursuant to Section 13.02 or 13.03, 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 13.05; provided, however, that if the Company
makes any payment of principal of (or premium, if any) or interest on any Note
following the reinstatement of its obligations, the Company shall be subrogated
to the rights of the Holders of such Notes to receive such payment from the
money held by the Trustee or Paying Agent.

interest in a Global Note shall deliver to the Trustee a written order given in

participant account of the Depositary to be credited with a beneficial interest
in the Global Note. The Trustee shall, in accordance with such instructions
instruct the Depositary to credit to the account of the Person specified in such
instructions a beneficial interest in the Global Note and to debit the account
of the Person making the transfer the beneficial interest in the Global Note
being transferred.

               (ii) Notwithstanding any other provisions of this Appendix (other
        than the provisions set forth in Section 2.4), a Global Note may not be

        nominee to a successor Depository or a nominee of such successor
        Depository.

               (iii) In the event that a Global Note is exchanged for Notes in
        definitive registered form pursuant to Section 2.4 hereof or Section
        3.04 of the Indenture, prior to the consummation of a Registered
        Exchange Offer or the effectiveness of a Shelf Registration Statement
        with respect to such Notes, such Notes may be exchanged only in
        accordance with such procedures as are substantially consistent with the
        provisions of this Section 2.3 (including the certification requirements
        set forth on the reverse of the Initial Notes intended to ensure that
        such transfers comply with Rule 144A and such other procedures as may

               Definitive Note, the Trustee shall permit











                                                                               8

               on Rule 144 (such certification to be in the form set forth on
               the reverse of the Note).

               (iii) After a transfer of any Initial Notes during the period of
        the effectiveness of a Shelf Registration Statement with respect to such
        Initial Notes, all require ments pertaining to legends on such Initial
        Note will cease to apply, the requirements requiring any such Initial
        Note issued to certain Holders be issued in global form will cease to
        apply, and a certificated Initial Note without legends will be available
        to the transferee of the Holder of such Initial Notes upon exchange of
        such transferring Holder's certificated Initial Note or directions to
        transfer such Holder's interest in the Global Note, as applicable.

        and certificated Initial Notes with the restricted notes legend set
        forth in Exhibit 1 hereto will be available to Holders of such Initial
        Notes that do not exchange their Initial Notes, and Exchange Notes in
        certificated or global form will be available to Holders that exchange
        such Initial Notes in such Registered Exchange Offer.

               (e) Cancellation or Adjustment of Global Note. At such time as
all beneficial interests in a Global Note have either been exchanged for
certificated or Definitive Notes, redeemed, repurchased or canceled, such Global
Note shall be returned to the Depository for cancellation or retained and
canceled by the Trustee. At any time prior to such











                                                                               9

cancellation, if any beneficial interest in a Global Note is exchanged for
certificated or Definitive Notes, redeemed, repurchased or canceled, the
principal amount of Notes represented by such Global Note shall be reduced and
an adjustment shall be made on the books and records of the Trustee (if it is
then the Notes Custodian for such Global Note) with respect to such Global Note,
by the Trustee, to reflect such reduction.

        beneficial owner of a Global Note, a member of, or a participant in the

        thereof, with respect to any ownership interest in the Notes or with

        other Person (other than the Depository) of any notice (including any

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

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

if at any time such Depository ceases to be a "clearing agency" registered under
the Exchange Act and a successor depositary is not appointed by the Company

continuing or (iii) the Company, in its sole discretion, notifies the Trustee in
writing that it elects to cause the issuance of certificated Notes under this
Indenture.

               (b) Any Global Note that is transferable to the beneficial owners
thereof pursuant to this Section shall be surrendered by the Depository to the
Trustee located in the Borough of Manhattan, The City of New York, to be so
transferred, in whole or from time to time in part, without charge, and the
Trustee shall authenticate and deliver, upon such transfer of each portion of
such Global Note, an equal aggregate principal amount of certificated Initial
Notes of authorized denominations. Any portion of a Global Note transferred
pursuant to this Section shall be executed, authenticated and delivered only in
denominations of $1,000 and any integral multiple thereof and registered in such
names as the Depository shall direct. Any certificated Initial Note delivered in
exchange for an interest in the Global Note shall, except as otherwise provided
by Section 2.3(d), bear the restricted notes legend set forth in Exhibit 1
hereto.

               (c) Subject to the provisions of Section 2.4(b), the registered
Holder of a Global Note 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 Notes.

               (d) In the event of the occurrence of either of the events
specified in Section 2.4(a), the Company will promptly make available to the
Trustee a reasonable supply of certificated Notes in definitive, fully
registered form without interest coupons.

                                                                               4

                     [FORM OF REVERSE SIDE OF INITIAL NOTE]

                      14-1/2% Senior Secured Note due 2009

1. Interest.

               CD RADIO INC., a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Note at the rate per annum shown above; provided, however, that if a
Registration Default (as defined in the Registration Rights Agreement) occurs,
additional interest will accrue on this Note at a rate of 0.50% per annum with
respect to the first 90-day period following any such Registration Default. The
amount of the additional interest will increase by an additional one-half of one
percent (0.50%) to a maximum of one and one-half percent (1.50%) per annum for
each subsequent 90-day period until such Registration Default has been cured.
The Company will pay interest semiannually on May 15 and November 15 of each
year. Interest on the Notes will accrue from the most recent date to which
interest has been paid or, if no interest has been paid, from May 18, 1999.
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 at the rate borne by
the Notes plus 1% per annum, and it shall pay interest on overdue installments
of interest at the same rate to the extent lawful.

2. Method of Payment.

               The Company will pay interest on the Notes (except defaulted
interest) to the Persons who are registered holders of Notes at the close of
business on the May 1 or November 1 next preceding the interest payment date
even if Notes are canceled after the record date and on or before the interest
payment date. Holders must surrender Notes to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. Payments in respect of the Notes represented by a Global Note
(including principal, premium and interest) will be made by wire transfer of
immediately available funds to the accounts specified by The Depository Trust
Company. The Company will make all payments in respect of a certificated Note
(including principal, premium and interest) by mailing a check to the registered
address of each Holder thereof;











                                                                               5

provided, however, that payments on a certificated Note will be made by wire
transfer to a U.S. dollar account maintained by the payee with a bank in the
United States if such Holder elects payment by wire transfer by giving written
notice to the Trustee or the paying agent to such effect designating such
account no later than 30 days immediately preceding the relevant due date for
payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent and Registrar.

               Initially, United States Trust Company of New York, a New York
banking corporation ("Trustee"), will act as paying agent and registrar. The
Company may appoint and change any paying agent, registrar or co-registrar
without notice. The Company or any of its domestically incorporated wholly owned
subsidiaries may act as paying agent, registrar or co-registrar.

4. Indenture.

               The Company issued the Notes under an Indenture dated as of May
15, 1999 ("Indenture"), between the Company and the Trustee. The terms of the
Notes include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act of 1939 (15 U.S.C. 'SS''SS'
77aaa-77bbbb) as in effect on the date of the Indenture (the "Act"). Terms
defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Notes are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

               The Notes are secured obligations of the Company. The Initial
Notes issued on the Issue Date and all Exchange Notes issued in exchange
therefore will be treated as a single class for all purposes under the
Indenture. The Indenture limits, among other things, (i) the incurrence of
additional debt by the Company and its subsidiaries, (ii) the payment of
dividends on capital stock of the Company and the purchase, redemption or
retirement of capital stock or subordinated indebtedness, (iii) the creation of
certain liens, (iv) certain transaction with affiliates, (v) sales of assets,
including capital stock of subsidiaries, (vi) sale and leaseback transactions,
(vii) restrict dividend or other payments to the Company, (viii) the issuance
and sale of shares in restricted subsidiaries, and (ix) certain consolidations,
mergers and transfers of assets. The Indenture also prohibits certain
restrictions on distributions from subsidiaries. All of those











                                                                               6

limitations and prohibitions, however, are subject to a number of important
qualifications contained in the Indenture.

5. Optional Redemption.

               Except as set forth in the next paragraph, the Notes may not be
redeemed prior to May 15, 2004. On and after that date, the Company may redeem
the Notes in whole at any time or in part from time to time at the following
redemption prices (expressed in percentages of principal amount), plus accrued
interest to the redemption date (subject to the right of Holders of record on
the relevant record date to receive interest due on the related interest payment
date):

               if redeemed during the 12-month period beginning May 15,



                            Period                             Percentage
                            ------                             ----------
                                                             
               2004...........................................  107.250%
               2005...........................................  104.833%
               2006...........................................  102.417%
               2007 and thereafter............................  100.000%

up to 35% of the aggregate principal amount of Notes with the proceeds of an
Equity Offering, at any time or from time to time, at a redemption price
(expressed as a percentage of principal amount) of 114.50%, plus accrued
interest to redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the related interest payment
date); provided, however, that immediately after giving effect to such
redemption, at least 65% of the original aggregate principal amount of the Notes

given within 60 days of the closing of such Equity Offering.

               Notice of redemption will be mailed at least 30 days but not more
than 60 days before the redemption date to each Holder of Notes to be redeemed
at his registered address. Notes in denominations larger than $1,000 may be

other conditions are satisfied, on and after such date interest ceases to accrue
on such Notes (or such portions thereof) called for redemption.

7. Security.

               The Notes will be secured by a first priority perfected security
interest in all the issued and outstanding common stock of Satellite CD Radio,
Inc., the Company's wholly owned subsidiary, on an equal basis with holders of
the Discount Notes pursuant to the Pledge Agreement.

               Further, as set forth in the Indenture, a portion of the net
proceeds of the Units offering will be used to purchase the Pledged Securities
in such amount as will be sufficient, upon receipt of scheduled interest on and
principal payments of such securities, to provide for payment in full of the
first six scheduled interest payments due on the Notes. The Pledged Securities
will be pledged by the Company to the Trustee for the benefit of the holders of
the Notes pursuant to the Collateral Pledge Agreement and will be held by the
Trustee in the Pledge Account.

8. Put Provisions.

               Upon a Change of Control, any Holder of Notes will have the right
to cause the Company to repurchase all or any part of the Notes of such Holder
at a repurchase price equal to 101% of the principal amount of the Notes to be
repurchased plus accrued interest to the date of repurchase (subject to the
right of holders of record on the relevant record date to receive interest due
on the related interest payment date) as provided in, and subject to the terms
of, the Indenture.

9. Denominations; Transfer; Exchange.

               The Notes are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Notes
in accordance with the Indenture. The Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes and fees required by law or permitted by the Indenture.










                                                                               8

10. Persons Deemed Owners.

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

11. Unclaimed Money.

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

12. Discharge and Defeasance.

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

13. Amendment, Waiver.

               Subject to certain exceptions set forth in the Indenture, (i) the
Indenture, the Collateral Documents or the Notes may be amended with the written
consent of the Holders of at least a majority in principal amount outstanding of
the Notes and (ii) any default or noncompliance with any provision may be waived
with the written consent of the Holders of a majority in principal amount
outstanding of the Notes. Subject to certain exceptions set forth in the
Indenture, without the consent of any Securityholder, the Company and the
Trustee may amend the Indenture or the Notes to cure any ambiguity, omission,
defect or inconsistency, or to comply with Article VIII of the Indenture, or to
provide for uncertificated Notes in addition to or in place of certificated
Notes, or to add guarantees with respect to the Notes or to secure the Notes, or
to add additional covenants or surrender rights and powers conferred on the
Company, or to comply with any request of the SEC in connection with qualifying
the Indenture under the Act, or to make any change that does not adversely
affect the rights of any Securityholder.











                                                                               9

14. Defaults and Remedies.

               Under the Indenture, Events of Default include (i) as to any
interest payment date occurring on or prior to May 15, 2002, default in the
payment of interest on the Notes when it becomes due and payable; and as to any
interest payment date thereafter, default for 30 days in payment of interest on
the Notes; (ii) default in payment of principal on the Notes at maturity, upon
redemption pursuant to paragraph 5 of the Notes, upon acceleration or otherwise,
or failure by the Company to redeem or purchase Notes when required; (iii)
failure by the Company to comply with other agreements in the Indenture or the
Notes, in certain cases subject to notice and lapse of time; (iv) certain
accelerations (including failure to pay within any grace period after final
maturity) of other Indebtedness of the Company if the amount accelerated (or so
unpaid) exceeds $10.0 million; (v) certain events of bankruptcy or insolvency
with respect to the Company and the Significant Subsidiaries; and (vi) certain
judgments or decrees for the payment of money in excess of $10.0 million. If an
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the Notes may declare all the Notes to be due
and payable immediately. Certain events of bankruptcy or insolvency are Events
of Default which will result in the Notes being due and payable immediately upon
the occurrence of such Events of Default.

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

15. Trustee Dealings with the Company.

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











                                                                              10

16. No Recourse Against Others.

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

17. Authentication.

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

18. Abbreviations.

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

19. CUSIP Numbers.

               Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures the Company has caused CUSIP numbers
to be printed on the Notes and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

20. Holders' Compliance with Registration Rights Agreement.

               Each Holder of a Note, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Rights Agreement, including,
without limitation, the obligations of the Holders with respect to a
registration and the indemnification of the Company to the extent provided
therein.











                                                                              11

21. Governing Law.

               THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

                      14-1/2% Senior Secured Note due 2009

1. Interest.

               CD RADIO INC., a Delaware corporation (such corporation, and its
successors and assigns under the Indenture hereinafter referred to, being herein
called the "Company"), promises to pay interest on the principal amount of this
Note at the rate per annum shown above; provided, however, that if a
Registration Default (as defined in the Registration Rights Agreement) occurs,
additional interest will accrue on this Note at a rate of 0.50% per annum with
respect to the first 90-day period following any such Registration Default.
(***). The amount of the additional interest will increase by an additional
one-half of one percent (0.50%) to a maximum of one and one-half percent (1.50%)
per annum for each subsequent 90- day period until such Registration Default has
been cured. The Company will pay interest semiannually on May 15 and November 15
of each year. Interest on the Notes will accrue from the most recent date to
which interest has been paid or, if no interest has been paid, from May 18,
1999. 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 at the rate borne by
the Notes plus 1% per annum, and it shall pay interest on overdue installments
of interest at the same rate to the extent lawful.




___________________

(***) Insert if at the time of issuance of the Exchange Note neither the
Registered Exchange Offer has been consummated nor a Shelf Registration
Statement has been declared effective in accordance with the Registration Rights
Agreement.











                                                                               4

2. Method of Payment.

               The Company will pay interest on the Notes (except defaulted
interest) to the Persons who are registered holders of Notes at the close of
business on the May 1 or November 1 next preceding the interest payment date
even if Notes are canceled after the record date and on or before the interest
payment date. Holders must surrender Notes to a Paying Agent to collect
principal payments. The Company will pay principal and interest in money of the
United States that at the time of payment is legal tender for payment of public
and private debts. Payments in respect of Notes (including principal, premium
and interest) will be made by wire transfer of immediately available funds to
the accounts specified by the holders thereof or, if no U.S. dollar account
maintained by the payee with a bank in the United States is designated by any
holder to the Trustee or the paying agent at least 30 days prior to the relevant
due date for payment (or such other date as the Trustee may accept in its
discretion), by mailing a check to the registered address of such holder.

3. Paying Agent and Registrar.

               Initially, United States Trust Company of New York, a New York
banking corporation ("Trustee"), will act as paying agent and registrar. The
Company may appoint and change any paying agent, registrar or co-registrar
without notice. The Company or any of its domestically incorporated wholly owned
subsidiaries may act as paying agent, registrar or co-registrar.

4. Indenture.

               The Company issued the Notes under an Indenture dated as of May
15, 1999 ("Indenture"), between the Company and the Trustee. The terms of the
Notes include those stated in the Indenture and those made part of the Indenture
by reference to the Trust Indenture Act of 1939 (15 U.S.C. 'SS''SS'
77aaa-77bbbb) as in effect on the date of the Indenture (the "Act"). Terms
defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture. The Notes are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

               The Notes are secured obligations of the Company. The Initial
Notes issued on the Issue Date, and all Exchange Notes issued in exchange
therefor will be treated as a single class for all purposes under the Indenture.
The Indenture limits, among other things, (i) the incurrence of additional











                                                                               5

however, are subject to a number of important qualifications contained in the
Indenture.

5. Optional Redemption.

               Except as set forth in the next paragraph, the Notes may not be
redeemed prior to May 15, 2004. On and after that date, the Company may redeem
the Notes in whole at any time or in part from time to time at the following
redemption prices (expressed in percentages of principal amount), plus accrued
interest to the redemption date (subject to the right of Holders of record on
the relevant record date to receive interest due on the related interest payment
date):

               if redeemed during the 12-month period beginning May 15,



                            Period                             Percentage
                            ------                             ----------
                                                             
               2004...........................................  107.250%
               2005...........................................  104.833%
               2006...........................................  102.417%
               2007 and thereafter............................  100.000%



         In addition, at any time prior to May 15, 2002, the Company may redeem
up to 35% of the aggregate principal amount of Notes with the proceeds of an
Equity Offering, at any time or from time to time, at a redemption price
(expressed as a percentage of principal amount) of 114.50%, plus accrued
interest to redemption date (subject to the right of Holders of record on the
relevant record date to receive interest due on the related interest payment
date); provided, however, that immediately after giving effect to such
redemption, at least 65% of the original aggregate principal amount of the Notes
outstanding; provided further, however, that notice of such











                                                                               6

redemption shall be given within 60 days of the closing of such Equity Offering.

6. Notice of Redemption.

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

7. Security.

               The Notes will be secured by a first priority perfected security
interest in all the issued and outstanding common stock of Satellite CD Radio
Inc., the Company's wholly owned subsidiary, on an equal basis with holders of
the Discount Notes pursuant to the Pledge Agreement.

               Further, as set forth in the Indenture, a portion of the net
proceeds of the Units offering will be used to purchase the Pledged Securities
in such amount as will be sufficient, upon receipt of scheduled interest on and
principal payments of such securities, to provide for payment in full of the
first six scheduled interest payments due on the Notes. The Pledged Securities
will be pledged by the Company to the Trustee for the benefit of the holders of
the Notes pursuant to the Collateral Pledge Agreement and will be held by the
Trustee in the Pledge Account.

8. Put Provisions.

               Upon a Change of Control, any Holder of Notes will have the right
to cause the Company to repurchase all or any part of the Notes of such Holder
at a repurchase price equal to 101% of the principal amount of the Notes to be
repurchased plus accrued interest to the date of repurchase (subject to the
right of holders of record on the relevant record date to receive interest due
on the related interest payment date) as provided in, and subject to the terms
of, the Indenture.











                                                                               7

9. Denominations; Transfer; Exchange.

               The Notes are in registered form without coupons in denominations
of $1,000 and whole multiples of $1,000. A Holder may transfer or exchange Notes
in accordance with the Indenture. The Trustee may require a Holder, among other
things, to furnish appropriate endorsements or transfer documents and to pay any
taxes and fees required by law or permitted by the Indenture.

10. Persons Deemed Owners.

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

11. Unclaimed Money.

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

12. Discharge and Defeasance.

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

13. Amendment, Waiver.

               Subject to certain exceptions set forth in the Indenture, (i) the
Indenture, the Collateral Documents or the Notes may be amended with the written
consent of the Holders of at least a majority in principal amount outstanding of
the Notes and (ii) any default or noncompliance with any provision may be waived
with the written consent of the Holders of a majority in principal amount
outstanding of the Notes. Subject to certain exceptions set forth in the
Indenture, without the consent of any Securityholder, the Company and the
Trustee may amend the Indenture or the Notes to cure any ambiguity, omission,
defect or inconsistency, or to comply with











                                                                               8

Article VIII of the Indenture, or to provide for uncertificated Notes in
addition to or in place of certificated Notes, or to add guarantees with respect
to the Notes or to secure the Notes, or to add additional covenants or surrender
rights and powers conferred on the Company, or to comply with any request of the
SEC in connection with qualifying the Indenture under the Act, or to make any
change that does not adversely affect the rights of any Securityholder.

14. Defaults and Remedies.

               Under the Indenture, Events of Default include (i) as to any
interest payment date occurring on or prior to May 15, 2002, default in the
payment of interest on the Notes when it becomes due and payable; and as to any
interest payment date thereafter, default for 30 days in payment of interest on
the Notes; (ii) default in payment of principal on the Notes at maturity, upon
redemption pursuant to paragraph 5 of the Notes, upon acceleration or otherwise,
or failure by the Company to redeem or purchase Notes when required; (iii)
failure by the Company to comply with other agreements in the Indenture or the
Notes, in certain cases subject to notice and lapse of time; (iv) certain
accelerations (including failure to pay within any grace period after final
maturity) of other Indebtedness of the Company if the amount accelerated (or so
unpaid) exceeds $10.0 million; (v) certain events of bankruptcy or insolvency
with respect to the Company and the Significant Subsidiaries; and (vi) certain
judgments or decrees for the payment of money in excess of $10.0 million. If an
Event of Default occurs and is continuing, the Trustee or the Holders of at
least 25% in principal amount of the Notes may declare all the Notes to be due
and payable immediately. Certain events of bankruptcy or insolvency are Events
of Default which will result in the Notes being due and payable immediately upon
the occurrence of such Events of Default.

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











                                                                               9

15. Trustee Dealings with the Company.

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

16. No Recourse Against Others.

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

17. Authentication.

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

18. Abbreviations.

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

19. CUSIP NUMBERS.

               Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures the Company has caused CUSIP numbers
to be printed on the Notes and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders. No representation is
made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of











                                                                              10

redemption and reliance may be placed only on the other identification numbers
placed thereon.

20. Holders' Compliance with Registration Rights Agreement.

               Each Holder of a Note, by acceptance hereof, acknowledges and
agrees to the provisions of the Registration Rights Agreement, including,
without limitation, the obligations of the Holders with respect to a
registration and the indemnification of the Company to the extent provided
therein.

21. Governing Law.

               THIS NOTE SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.
