SECTION 2.04. PAYING AGENT TO HOLD MONEY IN TRUST.

         The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent shall hold in trust for the benefit of
the Holders of the Notes or the Trustee all money held by the Paying Agent for
the payment of principal of, premium, if any, and interest on the Notes, and
shall notify the Trustee of any Default by the Company in making any such
payment. While any such Default continues, the Trustee may require a Paying
Agent to pay all money held by it to the Trustee. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee. Upon payment
over to the Trustee, the Paying Agent (if other than the Company) shall have no

Trustee is not the Registrar, the Company shall furnish to the Trustee at least
seven Business Days before each interest payment date and at such other times as
the Trustee may request in writing a list in such form and as of such date as

by a nominee of the Depositary to the Depositary or to another nominee of the
Depositary, or by the Depositary or any such nominee to a successor Depositary
or a nominee of such successor Depositary. All Global Notes will be exchanged by
the Company for Definitive Notes if (i) the Company delivers to the Trustee
notice from the Depositary that it is unwilling or unable to continue to act as
Depositary and a successor Depositary is not appointed by the Company within 90
days after the date of such notice from the Depositary, (ii) the Depositary has
ceased to be a clearing agency registered under the Exchange Act, (iii) the
Company in its sole discretion determines that the Global Notes (in whole but
not in part) should be exchanged for Definitive Notes and delivers a written
notice to such effect to the Trustee or (iv) there shall have occurred and be
continuing a Default or an Event of Default under this Indenture. In any such
case, the Company will notify the Trustee in writing that, upon surrender by the
Direct Participants and Indirect Participants of their interest in such Global
Note, Certificated Notes will be issued to each Person that such Direct
Participants and Indirect Participants and DTC identify as being the beneficial
owner of the related Notes. Global Notes also may be exchanged or replaced, in
whole or in part, as provided in Sections 2.07 and 2.10 of this Indenture. Every
Note authenticated and delivered in exchange for, or in lieu of, a Global Note
or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 of
this Indenture, shall be authenticated and delivered in the form of, and shall
be, a Global Note. A Global Note may not be exchanged for another Note other
than as provided in this Section 2.06. However, beneficial interests in a Global
Note may be transferred and exchanged as provided in Section 2.06(b), (c) or (f)
of this Indenture.

Indenture and the Applicable Procedures. Beneficial interests in the Restricted
Global Notes shall be subject to restrictions on transfer comparable to those
set forth in this Indenture to the extent required by the Securities Act.
Transfers of beneficial interests in the Global Notes also shall require

             accordance with the transfer restrictions set forth in the Private
             Placement Legend; provided, however, that prior to the expiration

             Purchaser) unless permitted by applicable law and made in
             compliance with subparagraphs (ii) and (iii) below. Beneficial
             interests in any Unrestricted Global Note may be transferred to
             Persons who take delivery thereof in the form of a beneficial
             interest in an Unrestricted Global Note. No written orders or
             instructions shall be required to be delivered to the Registrar to
             effect the transfers described in this Section 2.06(b)(i) unless
             specifically stated above.

                  (ii) All Other Transfers and Exchanges of Beneficial Interests

             in an amount equal to the beneficial interest to be transferred or
             exchanged and (2) instructions given in accordance with the
             Applicable Procedures containing information regarding the
             Participant account to be credited with such increase or, if

             to this Indenture, (B) (1) a written order from a Participant or an
             Indirect Participant given to the Depositary in accordance with the
             Applicable Procedures directing the Depositary to cause to be
             issued a Definitive Note in an amount equal to the beneficial
             interest to be transferred or exchanged and (2) instructions given
             by the Depositary to the Registrar containing information regarding
             the Person in whose name such Definitive Note shall be registered

             consummation of an Exchange Offer by the Company in accordance with
             Section 2.06(f), the requirements of

             upon receipt by the Registrar of the instructions contained in the
             Letter of Transmittal delivered by the Holder of such beneficial
             interests in the Restricted Global Notes. Upon satisfaction of all
             of the requirements for transfer or exchange of beneficial
             interests in Global Notes contained in this Indenture and the Notes
             or otherwise applicable under the Securities Act, the Trustee shall
             adjust the principal amount of the relevant Global Note(s) pursuant
             to Section 2.06(h).

                  (iii) Transfer of Beneficial Interests to Another Restricted
             Global Note. A beneficial interest in any Restricted Global Note
             may be transferred to a Person who takes delivery thereof in the
             form of a beneficial interest in another Restricted Global Note if

             Global Note. A beneficial interest in any Restricted Global Note
             may be exchanged by any Holder thereof for a beneficial interest in
             an Unrestricted Global Note or transferred to a Person who takes
             delivery thereof in the form of a beneficial interest in an
             Unrestricted Global Note if the exchange or transfer complies with
             the requirements of Section 2.06(b)(ii) above and:

                  the Registrar so requests or if the Applicable Procedures so
                  require, an Opinion of Counsel in form reasonably acceptable
                  to the Registrar to the effect that such exchange or transfer
                  is in compliance with the Securities Act and that the
                  restrictions on transfer contained in this Indenture and in
                  the Private Placement Legend are no longer required in order
                  to maintain compliance with the Securities Act.

                           Upon satisfaction of the conditions of any of the

                  amount of one of the Unrestricted Global Notes.

or a Restricted Definitive Note, as the case may be, to a beneficial interest is
effected pursuant to subparagraphs (ii)(B), (ii)(D) or (iii) above at a time
when an Unrestricted Global Note has not yet been issued, the Company shall

             payable upon exchange or transfer pursuant to Sections 2.10, 3.06,

                  (v) The Company shall not be required (A) to issue, to
             register the transfer of or to exchange any Notes during a period
             beginning at the opening of business on a Business Day 15 days
             before the day of any selection of Notes for redemption under
             Section 3.02 of this Indenture and ending at the close of business
             on the day of selection or (B) to register the transfer of or to
             exchange any Note so selected for redemption in whole or in part,
             except the unredeemed portion of any Note being redeemed in part.

                  (vi) Prior to due presentment for the registration of a
             transfer of any Note, the Trustee, any Agent and the Company may
             deem and treat the Person in whose name any Note is registered as
             the absolute owner of such Note for the purpose of receiving
             payment of principal of and interest on such Notes and for all
             other purposes, and none of the Trustee, any Agent or the Company
             shall be affected by notice to the contrary.

                  (vii) The Trustee shall authenticate Global Notes and
             Definitive Notes in accordance with the provisions of Section 2.02
             of this Indenture.

                  (viii) All certifications, certificates and Opinions of
             Counsel required to be submitted to the Registrar pursuant to this
             Section 2.06 to effect a registration of transfer or exchange may
             be submitted by facsimile.

SECTION 2.07. REPLACEMENT NOTES.

         If any mutilated Note is surrendered to the Trustee, or the Company and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee, upon the written
order of the Company signed by two Officers of the Company, shall authenticate a
replacement Note if the Trustee's requirements for replacements of Notes are
met. If required by the Trustee or the Company, an indemnity bond must be
supplied by the Holder that is sufficient in the judgment of the Trustee and the
Company to protect the Company, the Trustee, any Agent or any authenticating
agent from any loss which any of them may suffer if a Note is replaced. Each of
the Company and the Trustee may charge for its expenses in replacing a Note.

         Every replacement Note is an additional obligation of the Company.

SECTION 2.08. OUTSTANDING NOTES.

         The Notes outstanding at any time are all the Notes authenticated by
the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section as not outstanding.

         If a Note is replaced pursuant to Section 2.07, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

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

         Subject to Section 2.09, a Note does not cease to be outstanding
because the Company, a Subsidiary of the Company or an Affiliate of the Company
holds the Note.

SECTION 2.09. TREASURY NOTES.

         In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, any Subsidiary of the Company or any Affiliate of the Company shall be
considered as though not outstanding, except that for purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent, only Notes which a Responsible Officer knows to be so owned shall be
so considered. Notwithstanding the foregoing, Notes that are to be acquired by
the Company, any Subsidiary of the Company or an Affiliate of the Company
pursuant to an exchange offer, tender offer or other agreement shall not be
deemed to be owned by the Company, a Subsidiary of the Company or an Affiliate
of the Company until legal title to such Notes passes to the Company, such
Subsidiary or such Affiliate, as the case may be.

                                       35
<PAGE>   42

SECTION 2.10. TEMPORARY NOTES.

         Until definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes. Temporary Notes shall be
substantially in the form of definitive Notes but may have variations that the
Company and the Trustee consider appropriate for temporary Notes. Without
unreasonable delay, the Company shall prepare and the Trustee, upon receipt of
the written order of the Company signed by two Officers of the Company, shall
authenticate definitive Notes in exchange for temporary Notes. Until such
exchange, temporary Notes shall be entitled to the same rights, benefits and
privileges as definitive Notes.

SECTION 2.11. CANCELLATION.

         The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee shall cancel all Notes surrendered for registration of transfer,
exchange, payment, replacement or cancellation and shall destroy canceled Notes
(subject to the record retention requirement of the Exchange Act), unless the
Company directs canceled Notes to be returned to it. The Company may not issue
new Notes to replace Notes that it has redeemed or paid or that have been
delivered to the Trustee for cancellation. All canceled Notes held by the
Trustee shall be destroyed and certification of their destruction delivered to
the Company, unless by a written order, signed by two Officers of the Company,
the Company shall direct that canceled Notes be returned to it.

SECTION 2.12. DEFAULTED INTEREST.

         If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders of
the Notes on a subsequent special record date, which date shall be at the
earliest practicable date but in all events at least five Business Days prior to
the payment date, in each case at the rate provided in the Notes. The Company
shall, with the consent of the Trustee, fix or cause to be fixed each such
special record date and payment date. At least 15 days before the special record
date, the Company (or the Trustee, in the name of and at the expense of the
Company) shall mail to Holders of the Notes a notice that states the special
record date, the related payment date and the amount of such interest to be
paid.

SECTION 2.13. RECORD DATE.

         The record date for purposes of determining the identity of Holders of
the Notes entitled to vote or consent to any action by vote or consent
authorized or permitted under this Indenture shall be determined as provided for
in TIA Section 316(c).

<PAGE>   43

SECTION 2.14. CUSIP NUMBER.

         The Company in issuing the Notes may use a "CUSIP" number and, if it
does so, the Trustee shall use the CUSIP number 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 change in the CUSIP number.

                                   ARTICLE 3.
                                   REDEMPTION

SECTION 3.01. NOTICES TO TRUSTEE.

         If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.07, it shall furnish to the Trustee, at least
45 days (unless a shorter period is acceptable to the Trustee) but not more than
60 days before a redemption date, an Officers' Certificate setting forth (i) the
redemption date, (ii) the principal amount of Notes to be redeemed and (iii) the
redemption price. If the Company elects or is required to make the redemption
pursuant to Section 3.08, it shall furnish the Trustee, at least one but not
more than 10 Business Days before a redemption date, an Officers' Certificate
setting forth (i) the redemption date and (ii) the redemption price.

SECTION 3.02. SELECTION OF NOTES TO BE REDEEMED.

         If less than all of the Notes are to be redeemed at any time, the
selection of Notes for redemption will be made by the Trustee in compliance with
the requirements of the principal national securities exchange, if any, on which
the Notes are listed, or if the Notes are not so listed on a pro rata basis, by
lot or in accordance with any other method the Trustee considers fair and
appropriate, provided that no Notes with a principal amount of $1,000 or less
shall be redeemed in part. In the event of partial redemption by lot, the
particular Notes to be redeemed shall be selected, unless otherwise provided
herein, not less than 30 nor more than 60 days prior to the redemption date by
the Trustee from the outstanding Notes not previously called for redemption.

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

                                       37
<PAGE>   44

SECTION 3.03. NOTICE OF REDEMPTION.

         Subject to the provisions of Sections 3.08 and 3.09, at least 30 days
but not more than 60 days before a redemption date, the Company shall mail or
cause to be mailed, by first class mail, a notice of redemption to each Holder
whose Notes are to be redeemed at its registered address.

         The notice shall identify the Notes to be redeemed and shall state:

             (a) the redemption date;

             (b) the redemption price;

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

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

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

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

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

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

         At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; provided, however, that the
Company shall have delivered to the Trustee, at least 45 days (unless a shorter
period is acceptable to the Trustee) prior to the redemption date, an Officers'
Certificate requesting that the Trustee give such notice and setting forth the
information to be stated in such notice as provided in the preceding paragraph.

SECTION 3.04. EFFECT OF NOTICE OF REDEMPTION.

         Once notice of redemption is mailed in accordance with Section 3.03,
Notes called for redemption become due and payable on the redemption date at the
redemption price.

                                       38
<PAGE>   45

SECTION 3.05. DEPOSIT OF REDEMPTION PRICE.

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

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

SECTION 3.06. NOTES REDEEMED IN PART.

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

SECTION 3.07. OPTIONAL REDEMPTION.

         Except as provided in the next paragraph, the Notes will not be
redeemable at the Company's option prior to October 1, 2004. Thereafter, the
Notes will be subject to redemption at the option of the Company, in whole or in
part, upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below, together
with accrued and unpaid interest thereon to the applicable redemption date, if
redeemed during the 12-month period beginning on October 1 of the years
indicated below:

<TABLE>
<CAPTION>
YEAR                                           PERCENTAGE
----                                           ----------

2005 .....................................      102.594%
2006 .....................................      100.000%
</TABLE>

         Notwithstanding the foregoing, at any time prior to October 1, 2003,
the Company may redeem up to 35% of the aggregate principal amount of the Notes
outstanding at a redemption price equal to 110.375% of the principal amount
thereof on the repurchase date, together with accrued and unpaid interest to
such repurchase date, with the net cash proceeds of one or more public or
private sales (including

                                       39
<PAGE>   46

sales to EchoStar, regardless of whether EchoStar obtained such funds from an
offering of Equity Interests or Indebtedness of EchoStar or otherwise) of Equity
Interests (other than Disqualified Stock) of the Company (other than proceeds
from a sale to any Subsidiary of the Company or any employee benefit plan in
which the Company or any of its Subsidiaries participates); provided that: (a)
at least 65% in aggregate principal amount of the Notes originally issued remain
outstanding immediately after the occurrence of such redemption; and (b) the
sale of such Equity Interests is made in compliance with the terms of this
Indenture.

SECTION 3.08. MANDATORY REDEMPTION.

         Except as set forth in the immediately following sentence, the Notes
will not be subject to any mandatory redemption or sinking fund provisions.

         (a) In the event the Company has not delivered an Officers' Certificate
to the Trustee on or prior to October 25, 2000 certifying that the Company has
either (i) amended this Indenture to provide for a structure for the transaction
contemplated by Section 4.13 that will comply with the 1999 EDBS Notes
Indentures and will not cause the "push down" of the Indebtedness evidenced by
the Notes to occur prior to the time that EDBS would be permitted to incur such
Indebtedness and/or (ii) amended the 1999 EDBS Notes Indentures to provide that
the exchange feature set forth in Section 4.13 and the EDBS Exchange Offer will
not be considered a default under the 1999 EDBS Notes Indentures or (b) if the
Company delivers an Officers' Certificate to the Trustee on or prior to October
25, 2000 certifying that the Company is unable to obtain the consents to the
amendments referred to in clause (a) above, the Company shall redeem the Notes,
in whole and not in part, upon not less than 3 nor more than 10 days' notice, at
a price equal to 100% of the principal amount of the Notes, together with
accrued and unpaid interest thereon to the redemption date.

SECTION 3.09. OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

         When the cumulative amount of Excess Proceeds that have not been
applied in accordance with Section 4.10 and 4.16 herein or this Section 3.09,
exceeds $25.0 million, the Company shall be obligated to make an offer to all
Holders of the Notes (an "Excess Proceeds Offer") to purchase the maximum
principal amount of Notes that may be purchased out of such Excess Proceeds at
an offer price in cash in an amount equal to 101% of the principal amount
thereof, together with accrued and unpaid interest to the date fixed for the
closing of such offer in accordance with the procedures set forth in this
Indenture; provided, however, that the Excess Proceeds shall first be applied to
repurchase the 1999 EDBS Notes and the EDBS Exchange Notes, if any, that remain
outstanding as of the date the Excess Proceeds Offer is required to be made,
pursuant to the terms of the 1999 EDBS Notes Indentures and the EDBS Exchange
Indenture, respectively, and any Indebtedness that is on parity with the 1999
EDBS Notes or the EDBS Exchange Notes and is required to be repurchased with
such Excess Proceeds prior to the application of any Excess Proceeds to the
repurchase of the Notes and Indebtedness on parity with the Notes in an Excess
Proceeds Offer. To the extent the Company or a Restricted Subsidiary is required
under the terms of Indebtedness of the Company or such Restricted Subsidiary
which is pari passu with, or (in the case of any secured Indebtedness)

                                       40
<PAGE>   47

senior with respect to such collateral to, the Notes with any proceeds which
constitute Excess Proceeds under this Indenture, the Company shall make a pro
rata offer to the holders of all other pari passu Indebtedness (including the
Notes) with such proceeds. If the aggregate principal amount of Notes and other
pari passu Indebtedness surrendered by holders thereof exceeds the amount of
such Excess Proceeds, the Trustee shall select the Notes and other pari passu
Indebtedness to be purchased on a pro rata basis.

         The Excess Proceeds Offer shall remain open for a period of 20 Business
Days following its commencement and no longer, except to the extent that a
longer period is required by applicable law (the "Offer Period"). No later than
five Business Days after the termination of the Offer Period (the "Purchase
Date"), the Company shall purchase the maximum principal amount of Notes that
may be purchased with such Excess Proceeds (which maximum principal amount of
Notes shall be the "Offer Amount") or, if less than the Offer Amount has been
tendered, all Notes tendered in response to the Excess Proceeds Offer.

         If the Purchase Date is on or after an interest record date and on or
before the related interest payment date, any accrued interest shall be paid to
the Person in whose name a Note is registered at the close of business on such
record date, and no additional interest shall be payable to Holders who tender
Notes pursuant to the Excess Proceeds Offer.

         Upon the commencement of any Excess Proceeds Offer, the Company shall
send, by first class mail, a notice to each of the Holders of the Notes, with a
copy to the Trustee. The notice shall contain all instructions and materials
necessary to enable such Holders to tender Notes pursuant to the Excess Proceeds
Offer. The notice, which shall govern the terms of the Excess Proceeds Offer,
shall state:

              (a) that the Excess Proceeds Offer is being made pursuant to this
Section 3.09 and the length of time the Excess Proceeds Offer shall remain open;

              (b) the Offer Amount, the purchase price and the Purchase Date;

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

              (d) that any Note accepted for payment pursuant to the Excess
Proceeds Offer shall cease to accrue interest after the Purchase Date;

              (e) that Holders electing to have a Note purchased pursuant to any
Excess Proceeds Offer shall be required to surrender the Note, with the form
entitled "Option of Holder to Elect Purchase" on the reverse of the Note
completed, to the Company, a depositary, if appointed by the Company, or a
Paying Agent at the address specified in the notice at least three business days
before the Purchase Date;

              (f) that Holders shall be entitled to withdraw their election if
the Company, depositary or Paying Agent, as the case may be, receives, not later
than the expiration of the Offer Period, a telegram, telex, facsimile
transmission or letter setting forth the name of the Holder, the principal
amount of the Note the Holder

                                       41
<PAGE>   48

delivered for purchase and a statement that such Holder is withdrawing his
election to have the Note purchased;

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

              (h) that Holders whose Notes were purchased only in part shall be
issued new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered.

         On or before the Purchase Date, the Company shall, to the extent
lawful, accept for payment, on a pro rata basis to the extent necessary, the
Offer Amount of Notes or portions thereof tendered pursuant to the Excess
Proceeds Offer, or if less than the Offer Amount has been tendered, all Notes or
portion thereof tendered, and deliver to the Trustee an Officers' Certificate
stating that such Notes or portions thereof were accepted for payment by the
Company in accordance with the terms of this Section 3.09. The Company,
Depositary or Paying Agent, as the case may be, shall promptly (but in any case
not later than five days after the Purchase Date) mail or deliver to each
tendering Holder an amount equal to the purchase price of the Note tendered by
such Holder and accepted by the Company for purchase, and the Company shall
promptly issue a new Note, and the Trustee shall authenticate and mail or
deliver such new Note, to such Holder equal in principal amount to any
unpurchased portion of the Note surrendered. Any Note not so accepted shall be
promptly mailed or delivered by the Company to the Holder thereof. The Company
shall publicly announce the results of the Excess Proceeds Offer on the Purchase
Date. To the extent that the aggregate principal amount of Notes tendered
pursuant to an Excess Proceeds Offer is less than the amount of such Excess
Proceeds, the Company may use any remaining Excess Proceeds for general
corporate purposes. Upon completion of an Excess Proceeds Offer, the amount of
Excess Proceeds shall be reset at zero.

         Other than as specifically provided in this Section 3.09, any purchase
pursuant to this Section 3.09 shall be made pursuant to the provisions of
Sections 3.01 through 3.06.

                                   ARTICLE 4.
                                   COVENANTS

SECTION 4.01. PAYMENT OF NOTES.

         The Company shall pay or cause to be paid the principal of, premium, if
any, and interest on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than the Company, holds as of 10:00 a.m.
Eastern Time on the due date money deposited by or on behalf of the Company in
immediately available

                                       42

funds and designated for and sufficient to pay all principal, premium, if any,
and interest then due.

         The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
the then applicable interest rate on the Notes to the extent lawful; it shall
pay interest (including post-petition interest in any proceeding under any
Bankruptcy Law) on overdue installments of interest (without regard to any
applicable grace period) at the same rate to the extent lawful.

SECTION 4.02. MAINTENANCE OF OFFICE OR AGENCY.

         The Company shall maintain an office or agency (which may be an office
of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) 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 Company shall give prompt written notice to the
Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee.

         The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency for such purposes. The
Company shall give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other office or
agency.

         The Company hereby designates the Corporate Trust Office of the Trustee
as one such office or agency of the Company in accordance with Section 2.03.

SECTION 4.03. REPORTS.

              (a) Whether or not required by the rules and regulations of the
SEC, so long as any of the Notes remain outstanding, the Company shall cause
copies of all quarterly and annual financial reports and of the information,
documents, and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) which the Company is required
to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act
(including all information that would be required to be contained in Forms 10-Q
and 10-K) to be filed with the SEC and the Trustee and mailed to the Holders at
their addresses appearing in the register of Notes maintained by the Registrar,
in each case, within 15 days of filing with the SEC. If the Company is not
subject to the requirements of such Section 13 or 15(d) of the Exchange Act, the
Company shall nevertheless continue to cause the annual and quarterly financial
statements, including any notes thereto (and, with respect to annual reports, an
auditors' report by an accounting firm of established national reputation) and a
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," comparable to that which would have been required to

                                       43
<PAGE>   50

appear in annual or quarterly reports filed under Section 13 or 15(d) of the
Exchange Act (including all financial information that would be required to be
contained in Forms 10-Q and 10-K), to be so filed with the SEC for public
availability (to the extent permitted by the SEC) and the Trustee and mailed to
the Holders within 120 days after the end of the Company's fiscal years and

         Indenture, is less than the sum of (A) the difference of (x) cumulative

         financial statements are available at the time of such Restricted
         Payment; plus (B) an amount equal to 100% of the aggregate net cash

         Company or EDBS (other than Equity Interests sold to any Subsidiary of
         the Company), since the date of the 1999 EDBS Notes Indentures, but, in
         the case of any net cash proceeds, only to the extent such net cash
         proceeds are not used to redeem Notes pursuant to the second paragraph
         of Section 3.07 of this Indenture; plus (C) if any Unrestricted
         Subsidiary is designated by the Company as a Restricted Subsidiary, an
         amount equal to the fair market value of the net Investment by the
         Company, EDBS or a Restricted Subsidiary in such Subsidiary at the time
         of such designation; provided, however, that the foregoing sum shall
         not exceed the amount of the Investments made by the Company, EDBS or
         any Restricted Subsidiary in any such Unrestricted Subsidiary since the
         date of this Indenture, plus (D) 100% of any cash dividends and other
         cash distributions received by the Company and its Wholly Owned
         Restricted Subsidiaries from an Unrestricted Subsidiary to the extent

         Company or to a Wholly Owned Restricted Subsidiary or from the net cash
         proceeds from the sale, conveyance or other disposition of any such
         Investment; provided, however, that the foregoing sum shall not exceed,
         with respect to any Person in whom such Investment was made, the amount
         of Investments previously made by the Company or any Restricted
         Subsidiary in such Person which were included in computations made
         pursuant to this clause (iii).

         Company or to a Wholly Owned Restricted Subsidiary or from the net cash
         proceeds from the sale, conveyance or other disposition of any such
         Investment; provided, however, that the foregoing sum shall not exceed,

         on the date of this Indenture;

                  (ii) applicable law or regulation;

         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, provided that the
         Consolidated Cash Flow of such Person shall not be taken into account
         in determining whether such acquisition was permitted by the terms of
         this Indenture; except to the extent

         this Indenture), provided that the restrictions contained in the
         agreements governing such Refinancing Indebtedness are no more

         Indebtedness being refinanced;

                  (vi) this Indenture and the Notes;

                  (vii) any Indebtedness permitted to be incurred pursuant to

         Section 4.09 of the 1999 EDBS Notes Indentures or the EDBS Exchange
         Indenture;

                  (viii) Permitted Liens; or

                  (ix) any agreement for the sale of any Subsidiary or its
         assets that restricts distributions by that Subsidiary pending its
         sale; provided that during the entire period in which such encumbrance
         or restriction is effective, such sale (together with any other sales
         pending) would be permitted under the terms of this Indenture.

SECTION 4.09. INCURRENCE OF INDEBTEDNESS.

         The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee

notwithstanding the foregoing the Company may incur Indebtedness (including
Acquired Debt), if, after giving effect to the incurrence of such Indebtedness
and the application of the net proceeds thereof on a pro forma basis, the
Indebtedness to Cash Flow Ratio of the Company would not have exceeded 8.0 to 1.

         The foregoing limitation will not apply to any of the following

             entity other than in the ordinary course of its business in
             connection with, or in contemplation of, such entity being so
             acquired) in an amount not to exceed (A) $50 million in the
             aggregate for all such Persons other than those described in the

             exceed the cost of construction, acquisition or improvement of
             assets used in any business permitted under Section 4.17 of this
             Indenture, as well as any launch costs and insurance premiums
             related to such assets;

                  (ix) Hedging Obligations of the Company or any of its
             Restricted Subsidiaries covering Indebtedness of the Company or
             such Restricted Subsidiary to the extent the notional principal
             amount of such Hedging Obligation does not exceed the principal
             amount of the Indebtedness to which such Hedging Obligation
             relates; provided, however, that such Hedging Obligations are
             entered into to protect the Company and its Restricted Subsidiaries
             from fluctuation in interest rates on Indebtedness incurred in
             accordance with this Indenture;

                  (x) Indebtedness of the Company or any Restricted Subsidiary

             with the businesses permitted under Section 4.17 of this Indenture;

                  (xi) Indebtedness of the Company or any of its Restricted
             Subsidiaries the proceeds of which are used solely to finance the

                                       51

             construction and development of a call center owned by the Company
             or any of its Restricted Subsidiaries in Christainsburg, Virginia
             or any refinancing thereof; provided that the aggregate of all
             Indebtedness incurred pursuant to this clause (xi) shall in no
             event exceed $10 million at any one time outstanding;

                  (xii) the incurrence by the Company or any of its Restricted
             Subsidiaries of Indebtedness issued in exchange for, or the
             proceeds of which are used to extend, refinance, renew, replace,
             substitute or refund in whole or in part Indebtedness referred to
             in the first paragraph of this Section 4.09 or in clauses (i),
             (ii), (iii), (vi),(vii) and (viii), above ("Refinancing
             Indebtedness"); provided, however, that: (A) the principal amount
             of such Refinancing Indebtedness shall not exceed the principal
             amount and accrued interest of the Indebtedness so exchanged,
             extended, refinanced, renewed, replaced, substituted or refunded
             and any premiums payable and reasonable fees, expenses, commissions
             and costs in connection therewith; (B) the Refinancing Indebtedness
             shall have a final maturity equal to or later than, and a Weighted
             Average Life to Maturity equal to or greater than, the final
             maturity and Weighted Average Life to Maturity, respectively, of
             the Indebtedness being exchanged, extended, refinanced, renewed,
             replaced or refunded; and (C) the Refinancing Indebtedness shall be
             subordinated in right of payment to the Notes, if at all, on terms
             at least as favorable to the holders of Notes as those contained in
             the documentation governing the Indebtedness being extended,
             refinanced, renewed, replaced or refunded (a "Permitted
             Refinancing");

                  (xiii) the guarantee by the Company or any of its Restricted
             Subsidiaries of Indebtedness of the Company or a Restricted
             Subsidiary that was permitted to be incurred by another provision
             of this Section 4.09;

                  (xiv) Indebtedness under Capital Lease Obligations of the
             Company or any of its Restricted Subsidiaries with respect to no
             more than three direct broadcast satellites at any time;

                  (xv) Indebtedness represented by the EDBS Exchange Notes, the
             EDBS Exchange Guarantees and the EDBS Exchange Indenture.

         For purposes of determining compliance with this Section 4.09, if an
item of Indebtedness meets the criteria of more than one of the categories
described in clauses (i) through (xv) above or is permitted to be incurred
pursuant to the first paragraph of this Section 4.09 and also meets the criteria
of one or more of the categories described in clauses (i) through (xv) above,
the Company shall, in its sole discretion, classify such item of Indebtedness in
any manner that complies with this Section 4.09 and may from time to time
reclassify such item of Indebtedness in any manner in which such item could be
incurred at the time of such reclassification.

                                       52
<PAGE>   59

Accrual of interest and the accretion of accreted value will not be deemed to be
an incurrence of Indebtedness for purposes of this Section 4.09.

SECTION 4.10. ASSET SALES.

         If the Company or any Restricted Subsidiary, in a single transaction or
a series of related transactions:

         (a) sells, leases (in a manner that has the effect of a disposition),
conveys or otherwise disposes of any of its assets (including by way of a
sale-and-leaseback transaction), other than: (i) sales or other dispositions of
inventory in the ordinary course of business; (ii) sales or other dispositions
to the Company or a Wholly Owned Restricted Subsidiary of the Company by the
Company or any Restricted Subsidiary; (iii) sales or other dispositions of
accounts receivable to DNCC for cash in an amount at least equal to the fair
market value of such accounts receivable; (iv) sales or other dispositions of
rights to construct or launch satellites; and (v) sales or other dispositions
permitted under Section 4.21 of this Indenture (provided that the sale, lease,
conveyance or other disposition of all or substantially all of the assets of the
Company shall be governed by the provisions of Article 5 of this Indenture);

         (b) issues or sells Equity Interests of any Restricted Subsidiary
(other than any issue or sale of Equity Interests of ETC or a Subsidiary which
constitutes a Non-Core Asset permitted under Section 4.21 of this Indenture);

in either case, which assets or Equity Interests: (i) have a fair market value
in excess of $50 million (as determined in good faith by the Board of Directors
of the Company evidenced by a resolution of the Board of Directors of the
Company and set forth in an Officers' Certificate delivered to the Trustee); or
(ii) are sold or otherwise disposed of for net proceeds in excess of $50 million
(each of the foregoing, an "Asset Sale"), then:

                           (A) the Company or such Restricted Subsidiary, as the
                  case may be, must receive consideration at the time of such
                  Asset Sale at least equal to the fair market value (as
                  determined in good faith by the Board of Directors of the
                  Company evidenced by a resolution of the Board of Directors of
                  the Company) and set forth in an Officers' Certificate
                  delivered to the Trustee not later than ten business days
                  following a request from the Trustee which certificate shall
                  cover each Asset Sale made in the six months preceding the
                  date of request, as the case may be, of the assets sold or
                  otherwise disposed of; and

                           (B) at least 75% of the consideration therefor
                  received by the Company or such Restricted Subsidiary, as the
                  case may be, must be in the form of (x) cash, Cash Equivalents
                  or Marketable Securities, (y) any asset which is promptly (and
                  in no event later than 90 days after the date of transfer to
                  the Company or a Restricted Subsidiary) converted into cash;
                  provided that to the extent that such conversion is at a price
                  that is less than the fair market value (as determined above)
                  of such asset at the time of the Asset Sale in which such
                  asset was acquired, the Company shall be deemed to have made a

                                       53
<PAGE>   60

                  Restricted Payment in the amount by which such fair market
                  value exceeds the cash received upon conversion; and/or (z)
                  properties and capital assets (excluding Equity Interests) to
                  be used by the Company or any of its Restricted Subsidiaries
                  in a business permitted under Section 4.17 of this Indenture;
                  provided, however, that up to $40 million of assets in
                  addition to assets specified in clauses (x), (y) or (z) above
                  at any one time may be considered to be cash for purposes of
                  this clause (B), provided that the provisions of the next
                  paragraph are complied with as such non-cash assets are
                  converted to cash. The amount of any liabilities of the
                  Company or any Restricted Subsidiary that are assumed by or on
                  behalf of the transferee in connection with an Asset Sale (and
                  from which the Company or such Restricted Subsidiary are
                  unconditionally released) shall be deemed to be cash for the
                  purpose of this clause (B).

         The Net Proceeds from such Asset Sale shall be used only: (i) to
acquire assets used in, or stock or other ownership interests in a Person that
upon the consummation of such Asset Sale becomes a Restricted Subsidiary and
will be engaged primarily in, the business of the Company as described under
Section 4.17 of this Indenture, to repurchase the Notes, 1999 EDBS Notes or EDBS
Exchange Notes or if the Company sells any of its satellites after launch such
that the Company or its Restricted Subsidiaries own less than three in-orbit
satellites, only to purchase a replacement satellite; or (ii) as set forth in
the next sentence. Any Net Proceeds from any Asset Sale that are not applied or
invested as provided in the preceding sentence within 365 days after such Asset
Sale shall constitute "Excess Proceeds" and shall be applied to an offer to
purchase Notes and other senior Indebtedness of the Company if and when required
under Section 3.09 of this Indenture.

         Clause (B) of the second preceding paragraph shall not apply to all or
such portion of the consideration: (i) as is properly designated by the Company
in an Asset Sale as being subject to this paragraph; and (ii) with respect to
which the aggregate fair market value at the time of receipt of all
consideration received by the Company or any Restricted Subsidiary in all such
Asset Sales so designated does not exceed the amount that EDBS and its
Subsidiaries are permitted to designate as a result of the cash contributions
made to EDBS by EchoStar pursuant to the 1999 EDBS Notes Indentures, plus, to
the extent any such consideration did not satisfy clauses (B)(x) or (B)(z)
above, upon the exchange or repayment of such consideration for or with assets
which satisfy such clauses, an amount equal to the fair market value of such
consideration (evidenced by a resolution of the Board of Directors of the
Company and set forth in an Officers' Certificate delivered to the Trustee as
set forth in clause (A) above).

         In addition, clause (B) above shall not apply to any Asset Sale: (x)
where assets not essential to the direct broadcast satellite business are
contributed to a joint venture between the Company or one of its Restricted
Subsidiaries and a third party that is not an Affiliate of EchoStar or any of
its Subsidiaries; provided that following the sale, lease, conveyance or other
disposition the Company or one of its Wholly Owned Restricted Subsidiaries owns
at least 50% of the voting and equity interest in such joint venture, (y) to the
extent the consideration therefor received by the Company or a Restricted
Subsidiary would constitute Indebtedness or Equity

                                       54
<PAGE>   61

Interests of a Person that is not an Affiliate of EchoStar, the Company or one
of their respective Subsidiaries; provided that the acquisition of such
Indebtedness or Equity Interests is permitted under the provisions of Section
4.07 of this Indenture and (z) where assets sold are satellites, uplink centers
or call centers, provided that, in the case of clause (z) the Company and its
Restricted Subsidiaries continue to own at least three satellites, one uplink
center and one call center.

SECTION 4.11. LIMITATION ON TRANSACTIONS WITH AFFILIATES.

         The Company shall not and shall not permit any Restricted Subsidiary
to, sell, lease, transfer or otherwise dispose of any of its properties or
assets to, or purchase any property or assets from, or enter into any contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (including any Unrestricted Subsidiary) (each of the
foregoing, an "Affiliate Transaction"), unless:

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

         (b) if such Affiliate Transaction involves aggregate payments in excess
of $25 million, such Affiliate Transaction has been approved by a majority of
the disinterested members of the Board of Directors of the Company, and the
Company delivers to the Trustee no later than ten business days following a
request from the Trustee a resolution of the Board of Directors of the Company
set forth in an Officers' Certificate certifying that such Affiliate Transaction
has been so approved and complies with clause (a) above;

provided, however, that (i) the payment of compensation to directors and
management of EchoStar and its Subsidiaries; (ii) transactions between or among
the Company and its Wholly Owned Subsidiaries (other than Unrestricted
Subsidiaries of the Company); (iii) any dividend, distribution, sale, conveyance
or other disposition of any assets of, or Equity Interests in, any Non-Core
Assets or ETC or the proceeds of a sale, conveyance or other disposition
thereof, in accordance with the provisions of this Indenture; (iv) transactions
permitted by the provisions of this Indenture described above under clauses (1),
(2), (4), (5), (6), (8), (9), (10), (11), (14) and (15) of the second paragraph
of Section 4.07 of this Indenture; (v) so long as it complies with clause (a)
above, the provision of backhaul, uplink, transmission, billing, customer
service, programming acquisition and other ordinary course services by the
Company or any of its Restricted Subsidiaries to Satellite Communications
Operating Corporation and to Transponder Encryption Services Corporation on a
basis consistent with past practice; and (vi) any transactions between the
Company or any Restricted Subsidiary of the Company and any Affiliate of the
Company the Equity Interests of which Affiliate are owned solely by the Company
or one of its Restricted Subsidiaries, on the one hand, and by Persons who are
not Affiliates of the Company or Restricted Subsidiaries of the Company, on the
other hand, shall, in each case, not be deemed Affiliate Transactions.

                                       55
<PAGE>   62

SECTION 4.12. 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 on
any asset now owned or hereafter acquired, or on any income or profits therefrom
or assign or convey any right to receive income therefrom, except Permitted
Liens.

SECTION 4.13. EXCHANGE OF NOTES FOR EDBS EXCHANGE NOTES.

         (a) Subject to the provisions described in this Section 4.13, EDBS will
be required to make an offer (the "EDBS Exchange Offer") to exchange all of the
then outstanding Notes for the EDBS Exchange Notes as soon as practical
following the date on which EDBS is permitted to incur Indebtedness in an amount
equal to the then outstanding principal amount of Notes under the first
paragraph of Section 4.09 of the 1999 EDBS Notes Indentures and such incurrence
of Indebtedness would not otherwise cause any breach or violation of, or result
in a default under, the terms of the 1999 EDBS Notes Indentures.

         (b) The EDBS Exchange Notes will be substantially identical to the
Notes, however, among other things (i) EDBS shall be the issuer thereof instead
of the Company, (ii) to the extent described below, certain Subsidiaries of EDBS
(the "EDBS Exchange Notes Guarantors") will guarantee (the "EDBS Exchange
Guarantees") the EDBS Exchange Notes to the same extent that such Subsidiaries
have guaranteed the 1999 EDBS Notes and (iii) modifications may be made in the
EDBS Exchange Notes in order to assure that the execution and delivery of the
EDBS Exchange Notes by EDBS and the incurrence of such Indebtedness do not
breach or violate or cause a default under the 1999 EDBS Notes and 1999 EDBS
Notes Indentures. The EDBS Exchange Indenture will be substantially identical to
this Indenture; provided, however, modifications will be made to reflect the
addition of the EDBS Exchange Guarantees, that the EDBS Exchange Notes
Guarantors are parties to the EDBS Exchange Indenture, and to ensure that the
execution and delivery of the EDBS Exchange Indenture by EDBS does not breach or
violate or cause a default under the 1999 EDBS Notes and 1999 EDBS Notes
Indentures.

         (c) As soon as reasonably practicable following the first date (as
reflected in EDBS' most recent quarterly or annual financial statements) on
which EDBS is permitted under the 1999 EDBS Notes Indentures to commence the
EDBS Exchange Offer (the "Exchange Trigger Date"), the Company shall cause EDBS
and the EDBS Exchange Notes Guarantors to (a) file a registration statement with
the SEC relating to the EDBS Exchange Offer, (b) use their reasonable efforts to
cause such registration statement to be declared effective as soon as
practicable by the SEC and (c) qualify the EDBS Exchange Indenture and the
trustee under the EDBS Exchange Indenture under the TIA.

         (d) The Company agrees that from the date hereof and through the
consummation of the EDBS Exchange Offer it shall prevent EDBS and its
Subsidiaries from incurring Indebtedness pursuant to the first paragraph of
Section 4.09 of the 1999 EDBS Notes Indentures in amounts that would cause EDBS
to not be permitted to incur the Indebtedness represented by the EDBS Exchange
Notes pursuant to such section. Notwithstanding the foregoing sentence, EDBS and
its Subsidiaries will be permitted to incur Indebtedness pursuant to clauses (i)
through (xiv) of the second paragraph of Section 4.09 of the 1999 EDBS Notes
Indentures.

                                       56
<PAGE>   63

         (e) At the time of the EDBS Exchange Offer, each Subsidiary of EDBS
that is a guarantor of the 1999 EDBS Notes will become an EDBS Exchange Notes
Guarantor in connection with the EDBS Exchange Offer except to the extent such
Subsidiary would, as a result of such Subsidiary becoming an EDBS Exchange Notes
Guarantor, be in breach or violation of, or cause a default under the 1999 EDBS
Notes and the 1999 EDBS Notes Indentures, or in default under, any contract or
agreement that it is a party to or otherwise bound; provided that if after the
EDBS Exchange Offer such Subsidiary is still a guarantor of the 1999 EDBS Notes
and it could become an EDBS Exchange Notes Guarantor without breaching or
violating or being in default under any contract or agreement, EDBS shall
promptly cause such Subsidiary to become an EDBS Exchange Notes Guarantor. The
EDBS Exchange Indenture will provide that only EDBS and the EDBS Exchange Notes
Guarantors may incur Indebtedness pursuant to the indebtedness to cash flow
ratio test to be contained therein.

         (f) The Company agrees that, within ten business days after the
registration statement referred to in subsection (c) above has been declared
effective by the SEC, it shall cause EDBS and the EDBS Exchange Notes Guarantors
to send a written notice of exchange by mail to each holder of record of Notes,
which notice shall state (i) that EDBS and the EDBS Exchange Notes Guarantors
are making an offer to exchange the EDBS Exchange Notes and the EDBS Exchange
Guarantees for the Notes pursuant to Section 4.13 of this Indenture and (ii) the
date fixed for exchange (the "Exchange Date"), which date shall not be less than
30 days nor more than 45 days following the date on which such notice is mailed
(except as provided in the last sentence of this paragraph).

         (g) If on the Exchange Date, holders of at least 90% in aggregate
principal amount of the then outstanding Notes have accepted the Exchange Offer,
then, without any further action on the part of the Company or EDBS or any EDBS
Exchange Notes Guarantors, all of the then outstanding Notes shall be deemed to
have been exchanged for EDBS Exchange Notes and the related EDBS Exchange
Guarantees. On the Exchange Date, if the conditions set forth in clauses (A)
through (D) below are satisfied and if the exchange is then permitted under the
1999 EDBS Notes Indentures, the Company shall cause EDBS and the EDBS Exchange
Notes Guarantors to issue, and EDBS and the EDBS Exchange Notes Guarantors shall
issue, the EDBS Exchange Notes and the EDBS Exchange Guarantees in exchange for
the Notes as provided in subsection (h), provided that on the Exchange Date: (A)
a registration statement relating to the EDBS Exchange Notes and the EDBS
Exchange Guarantees shall have been declared effective under the Securities Act
prior to such exchange and shall continue to be in effect on the Exchange Date
or EDBS shall have obtained a written opinion of counsel that an exemption from
the registration requirements of the Securities Act is available for such
exchange and that upon receipt of such EDBS Exchange Notes and EDBS Exchange
Guarantees pursuant to such exchange made in accordance with such exemption,
each holder (assuming such holder is not an Affiliate of EDBS) thereof will not
be subject to any restrictions imposed by the Securities Act upon the resale
thereof, except to the extent such holder is an Affiliate of EDBS, and such
exemption is relied upon by EDBS for such exchange; (B) the EDBS Exchange
Indenture and the trustee under the EDBS Exchange Indenture shall have been
qualified under the TIA; (C) immediately after giving effect to such exchange,
no Default or Event of Default

                                       57
<PAGE>   64

(each as defined in the EDBS Exchange Indenture) would exist under the EDBS
Exchange Indenture; and (D) EDBS and the EDBS Exchange Notes Guarantors shall
have delivered to the trustee under the EDBS Exchange Indenture a written
opinion of counsel, dated the date of exchange, regarding the satisfaction of
the conditions set forth in clauses (A), (B) and (C). If (i) the issuance of the
EDBS Exchange Notes and EDBS Exchange Guarantees is not permitted on the
Exchange Date or (ii) any of the conditions set forth in clause (A) through (D)
of the preceding sentence are not satisfied on the Exchange Date, the Company
shall cause EDBS and the EDBS Exchange Notes Guarantors to use their reasonable
efforts to satisfy such conditions and effect such exchange as soon as
practicable.

         (h) Upon any exchange pursuant to subsection (g), the Holders of
outstanding Notes will be entitled to receive an amount of EDBS Exchange Notes
in principal amount equal to the principal amount of Notes exchanged. The EDBS
Exchange Notes will be issued in registered form, without coupons. EDBS Exchange
Notes issued in exchange for notes will be issued in principal amounts of $1,000
and integral multiples of $1,000 to the extent possible. On and after the
Exchange Date, interest will cease to accrue on the Notes tendered for exchange
as of the last interest payment date of the Notes prior to the Exchange Date,
and all rights of the holders of Notes (except the right to receive the EDBS
Exchange Notes) will terminate. Interest will accrue on the EDBS Exchange Notes
beginning on the date immediately following the last interest payment date of
the Notes. The Person entitled to receive the EDBS Exchange Notes issuable upon
such exchange will be treated for all purposes as the registered holder of such
EDBS Exchange Note.

         (i) If less than 90% in aggregate principal amount of the then
outstanding Notes accept the Exchange Offer, the Notes not accepting the
Exchange Offer will remain outstanding pursuant to this Indenture and the Notes
tendered for exchange will be exchanged for EDBS Exchange Notes and EDBS
Exchange Guarantees.

         (j) The Company and its Subsidiaries shall comply with the provisions
of the Exchange Act in connection with the EDBS Exchange Offer, to the extent
applicable.

SECTION 4.14. CORPORATE EXISTENCE.

         Subject to Article 5 of this Indenture and the next succeeding
paragraph of this Section 4.14, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect (i) its existence
as a corporation, and subject to 4.10 and 4.21, the corporate, partnership or
other existence of any Restricted Subsidiary, in accordance with the respective
organizational documents (as the same may be amended from time to time) of the
Company or any Restricted Subsidiary and (ii) subject to Section 4.10 and 4.21,
the rights (charter and statutory), licenses and franchises of the Company and
its Restricted Subsidiaries; provided, however, that the Company shall not be
required to preserve any such right, license or franchise, or the corporate,
partnership or other existence of any Restricted Subsidiary if the Board of
Directors shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and its Subsidiaries, taken as a
whole, and that the loss thereof is not adverse in any material respect to the
Holders of the Notes.

                                       58

SECTION 4.15. OFFER TO PURCHASE UPON CHANGE IN CONTROL.

         Upon the occurrence of a Change of Control, the Company will be
required to make an offer (a "Change of Control Offer") to each Holder of Notes
to repurchase all or any part (equal to $1,000 or an integral multiple thereof)
of such Holder's Notes at a purchase price equal to 101% of the aggregate
principal amount thereof, together with accrued and unpaid interest thereon to
the date of repurchase (in either case, the "Change of Control Payment"). Within
15 days following any Change of Control, the Company shall mail a notice to each
Holder stating:

         (a) that the Change of Control Offer is being made pursuant to the
covenant entitled "Section 4.15 - Offer to Purchase Upon Change in Control";

         (b) the purchase price and the purchase date, which shall be no earlier
than 30 days nor later than 40 days after the date such notice is mailed (the
"Change of Control Payment Date");

         (c) that any Notes not tendered will continue to accrue interest in
accordance with the terms of this Indenture;

         (d) that, unless the Company defaults in the payment of the Change of
Control Payment, all Notes accepted for payment pursuant to the Change of
Control Offer shall cease to accrue interest after the Change of Control Payment
Date;

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

         (f) that Holders whose Notes are being purchased only in part will be
issued new Notes equal in principal amount to the unpurchased portion of the
Notes surrendered, which unpurchased portion must be equal to $1,000 in
principal amount or an integral multiple thereof; and

         (g) any other information material to such Holder's decision to tender
Notes.

         The Company will comply with the requirements of Rule 14e-1 under the

extent such laws and regulations are applicable in connection with the
repurchase of the Notes in connection with a Change of Control.

SECTION 4.16. MAINTENANCE OF INSURANCE.

         At all times, the Company, EDBS or a Wholly Owned Restricted Subsidiary
of the Company will maintain and be the named beneficiary under Satellite

or leased by the Company or its Subsidiaries (insured in an amount at least
equal to the depreciated cost of such satellites)("Insured Satellites").

         If the Company or its Restricted Subsidiaries receive proceeds from any
Satellite Insurance covering any satellite owned by the Company or any of its
Restricted Subsidiaries, or in the event that the Company or any of its
Subsidiaries receives proceeds from any insurance maintained by any satellite
manufacturer or any launch provider covering any of such satellites, all such
proceeds (including any cash, Cash Equivalents or Marketable Securities deemed
to be proceeds of Satellite Insurance pursuant to the respective definition
thereof) shall be used only: (i) to purchase a replacement satellite if at such
time the Company and a Restricted Subsidiary then own less than the required
number of Insured Satellites as provided in the first paragraph of this Section
4.16, provided that if such replacement satellite is of lesser value compared to
the insured satellite, any insurance proceeds remaining after purchase of such
replacement satellite must be applied to the construction, launch and insurance
of a satellite of equal or greater value as compared to the insured satellite
(or in accordance with clause (iii) below); (ii) for purposes permitted under
Section 4.17 hereof if at such time the Company and its Restricted Subsidiaries
own the required number of Insured Satellites as provided in the first paragraph
of this Section 4.16 (or in accordance with clause (iii) below); or (iii) to the
extent that such proceeds are not applied or contractually committed to be
applied as described in (i) or (ii) above within 365 days of the receipt of such
proceeds as "Excess Proceeds" to be applied to an offer to purchase Notes as set
forth under Section 3.09 hereof.

SECTION 4.17. ACTIVITIES OF THE COMPANY.

         Neither the Company nor any of its Restricted Subsidiaries may engage
in any business other than developing, owning, engaging in and dealing with all
or any part of the business of domestic and international media, entertainment,
electronics or communications, and reasonably related extensions thereof,
including but not limited to the purchase, ownership, operation, leasing and
selling of, and generally dealing in or with, one or more communications
satellites and the transponders thereon, and communications uplink centers, the
acquisition, transmission, broadcast, production and other provision of

         The Company:

         (a) may, and may permit any of its Subsidiaries to, notwithstanding the
provisions of Section 4.07 of this Indenture, make Investments in an Accounts
Receivable Subsidiary: (i) the proceeds of which are applied within five
Business Days of the making thereof solely to finance: (A) the purchase of
accounts receivable of the Company and its Subsidiaries or (B) payments required
in connection with the termination of all then existing arrangements relating to
the sale of accounts receivable or participation interests therein by an
Accounts Receivable Subsidiary (provided that the Accounts Receivable Subsidiary
shall receive cash, Cash Equivalents and accounts receivable having an aggregate
fair market value not less than the amount of such payments in exchange
therefor) and (ii) in the form of Accounts Receivable Subsidiary Notes to the
extent permitted by clause (b) below;

         (b) shall not, and shall not permit any of its Subsidiaries to, sell
accounts receivable to an Accounts Receivable Subsidiary except for
consideration in an amount not less than that which would be obtained in an
arm's length transaction and solely in the form of cash or Cash Equivalents;
provided that an Accounts Receivable Subsidiary may pay the purchase price for
any such accounts receivable in the form of Accounts Receivable Subsidiary Notes
so long as, after giving effect to the issuance of any such Accounts Receivable
Subsidiary Notes, the aggregate principal amount of all Accounts Receivable
Subsidiary Notes outstanding shall not exceed 20% of the aggregate purchase
price paid for all outstanding accounts receivable purchased by an Accounts
Receivable Subsidiary since the date of this Indenture (and not written off or
required to be written off in accordance with the normal business practice of an
Accounts Receivable Subsidiary);

         (c) shall not permit an Accounts Receivable Subsidiary to sell any
accounts receivable purchased from the Company or its Subsidiaries or
participation interests therein to any other Person except on an arm's length
basis and solely for consideration in the form of cash or Cash Equivalents or
certificates representing undivided interests of a Receivables Trust; provided
an Accounts Receivable Subsidiary may not sell such certificates to any other
Person except on an arm's length basis and solely for consideration in the form
of cash or Cash Equivalents;

         (d) shall not, and shall not permit any of its Subsidiaries to, enter
into any guarantee, subject any of their respective properties or assets (other
than the accounts receivable sold by them to an Accounts Receivable Subsidiary)
to the satisfaction of any liability or obligation or otherwise incur any
liability or obligation (contingent or otherwise), in each case, on behalf of an
Accounts Receivable Subsidiary or in connection with any sale of accounts
receivable or participation interests therein by or to an Accounts Receivable
Subsidiary, other than obligations relating to breaches of representations,
warranties, covenants and other agreements of the Company or any of its
Subsidiaries with respect to the accounts receivable sold by the Company or any
of its Subsidiaries to an Accounts Receivable Subsidiary or with respect to the
servicing thereof; provided that neither the Company nor any of its Subsidiaries
shall at any time guarantee or be otherwise liable for the collectibility of
accounts receivable sold by them;

         (e) shall not permit an Accounts Receivable Subsidiary to engage in any
business or transaction other than the purchase and sale of accounts receivable
or

                                       61
<PAGE>   68

participation interests therein of the Company and its Subsidiaries and
activities incidental thereto;

         (f) shall not permit an Accounts Receivable Subsidiary to incur any
Indebtedness other than the Accounts Receivable Subsidiary Notes, Indebtedness
owed to the Company and Non-Recourse Indebtedness; provided that the aggregate
principal amount of all such Indebtedness of an Accounts Receivable Subsidiary
shall not exceed the book value of its total assets as determined in accordance
with GAAP;

         (g) shall cause any Accounts Receivable Subsidiary to remit to the
Company or a Restricted Subsidiary of the Company on a monthly basis as a
distribution all available cash and Cash Equivalents not held in a collection
account pledged to acquirers of accounts receivable or participation interests
therein, to the extent not applied to (i) pay interest or principal on the
Accounts Receivable Subsidiary Notes or any Indebtedness of such Accounts
Receivable Subsidiary owed to the Company, (ii) pay or maintain reserves for
reasonable operating expenses of such Accounts Receivable Subsidiary or to
satisfy reasonable minimum operating capital requirements or (iii) to finance
the purchase of additional accounts receivable of the Company and its
Subsidiaries; and

         (h) shall not, and shall not permit any of its Subsidiaries to, sell
accounts receivable to, or enter into any other transaction with or for the
benefit of, an Accounts Receivable Subsidiary (i) if such Accounts Receivable
Subsidiary pursuant to or within the meaning of any Bankruptcy Law (A) commences
a voluntary case, (B) consents to the entry of an order for relief against it in
an involuntary case, (C) consents to the appointment of a custodian of it or for
all or substantially all of its property, (D) makes a general assignment for the

SECTION 4.21. DISPOSITIONS OF ETC AND NON-CORE ASSETS.

         Notwithstanding Section 4.07 and Section 4.10 of this Indenture, in the
event that the Indebtedness to Cash Flow Ratio of the Company would not have
exceeded 6.0 to 1 on a pro forma basis after giving effect to the sale of all of
the Company's or its Subsidiaries', Equity Interests in or assets of ETC, then
(1) the payment of any dividend or distribution consisting of Equity Interests
or assets of ETC or the proceeds of a sale, conveyance or other disposition of
such Equity Interests or assets or the sale, conveyance or other disposition of
Equity Interests or assets of ETC or the proceeds of a sale, conveyance or other
disposition of such Equity Interests or assets shall not constitute a Restricted
Payment and (2) the sale, conveyance or other disposition of the Equity
Interests or assets of ETC or the proceeds of a sale, conveyance or other
disposition of such Equity Interests or assets shall not constitute an Asset
Sale and (3) provided that the Company designates ETC as an Unrestricted

                                       62
<PAGE>   69

Subsidiary, ETC shall be discharged and released from all covenants and
restrictions contained in this Indenture; provided that no such payment,
dividend, distribution, sale, conveyance or other disposition of any kind
(collectively, a "Payout") described in clauses (1) and (2) above shall be
permitted if at the time of such Payout (1) after giving pro forma effect to
such Payout, the Company would not have been permitted under Section 4.07 of
this Indenture to make a Restricted Payment in an amount equal to the total (the
"ETC Amount Due") of (x) the amount of all Investments (other than the
contribution of (i) title to the headquarters building of ETC in Inverness,
Colorado and the tangible assets therein to the extent used by ETC as of the
date of this Indenture and (ii) patents, trademarks and copyrights applied for
or granted as of the date of this Indenture to the extent used by ETC or result
from the business of ETC, in each case, to ETC) made in ETC by the Company or
its Restricted Subsidiaries since the date of this Indenture (which, in the case
of Investments in exchange for assets, shall be valued at the fair market value
of each such asset at the time each such Investment was made) minus (y) the
amount of the after-tax value of all cash returns on such Investments paid to
the Company or its Wholly Owned Restricted Subsidiaries (or, in the case of a
non-Wholly Owned Restricted Subsidiary, the pro rata portion thereof
attributable to the Company) minus (z) $50 million and (2) any contract,
agreement or understanding between ETC and the Company or any Restricted
Subsidiary of the Company and any loan or advance to or guarantee with, or for
the benefit of, ETC issued or made by the Company or one of its Restricted
Subsidiaries, is on terms that are less favorable to the Company or its
Restricted Subsidiaries than those that would have been obtained in a comparable
transaction by the Company or such Restricted Subsidiaries with an unrelated
Person, all as evidenced by a resolution of the Board of Directors of the
Company set forth in an Officers' Certificate delivered to the Trustee, within
ten business days of a request by the same, certifying that each such contract,
agreement, understanding, loan, advance and guarantee has been approved by a
majority of the members of such Board. In the event that at the time of such
Payout, the condition set forth in clause (1) of the proviso of the preceding
sentence cannot be satisfied, ETC may seek to have a Person other than the
Company or one of its Restricted Subsidiaries pay in cash an amount to the
Company or its Restricted Subsidiaries such that after taxes, such amount is
greater than or equal to the ETC Amount Due or the portion of the ETC Amount Due
which would not have been permitted to be made as a Restricted Payment by the
Company; provided that such payment shall be treated for purposes of this
Section 4.21 as a cash return on the Investments made in ETC and provided
further that for all purposes under this Indenture, such payment shall not be
included in any calculation under clauses (iii)(A) through (iii)(E) of the first
paragraph of Section 4.07 of this Indenture. To the extent that the ETC Amount
Due or any portion thereof would have been permitted to be made as a Restricted
Payment by the Company and was not paid by another Person as permitted by the
preceding sentence, the Company shall be deemed to have made a Restricted
Payment in the amount of such ETC Amount Due or portion thereof, as the case may
be.

         Notwithstanding Section 4.07 and Section 4.10 of this Indenture, (1)
the payment of any dividend or distribution consisting of Equity Interests or
assets of any Non-Core Asset or the proceeds of a sale, conveyance or other
disposition of such Equity Interests or assets or the sale, conveyance or other
disposition of Equity Interests in or assets of any Non-Core Asset or the
proceeds of a sale, conveyance or

                                       63
<PAGE>   70

other disposition of such Equity Interests or assets shall not constitute a
Restricted Payment and (2) the sale, conveyance or other disposition of the
Equity Interests or assets of any Non-Core Asset or the proceeds of a sale,
conveyance or other disposition of such Equity Interests or assets shall not
constitute an Asset Sale; and (3) provided the Company designates such Non-Core
Asset as an Unrestricted Subsidiary, such Non-Core Asset shall be released from
all covenants and restrictions contained in this Indenture; provided that no
Payout of any Non-Core Asset shall be permitted such as described in clauses (1)
and (2) above if at the time of such Payout (1) after giving pro forma effect to
such Payout, the Company would not have been permitted under Section 4.07 of
this Indenture to make a Restricted Payment in an amount equal to the total (the
"Non-Core Asset Amount Due") of (x) the amount of all Investments made in such
Non-Core Asset by the Company or its Restricted Subsidiaries since the date of
this Indenture (which, in the case of Investments in exchange for assets, shall
be valued at the fair market value of each such asset at the time each such
Investment was made) minus (y) the amount of the after-tax value of all cash
returns on such Investments paid to the Company or its Wholly Owned Restricted
Subsidiaries (or, in the case of a non-Wholly Owned Restricted Subsidiary, the
pro rata portion thereof attributable to the Company) minus (z) $50 million in
the aggregate for all such Payouts and $10 million for any single such Payout
and (2) any contract, agreement or understanding between or relating to a
Non-Core Asset and the Company or a Restricted Subsidiary of the Company and any
loan or advance to or guarantee with, or for the benefit of, a Restricted
Subsidiary which is a Non-Core Asset issued or made by the Company or one of its
Restricted Subsidiaries, is on terms that are less favorable to the Company or
its Restricted Subsidiaries than those that would have been obtained in a
comparable transaction by the Company or such Restricted Subsidiaries with an
unrelated Person, all as evidenced by a resolution of the Board of Directors of
the Company set forth in an Officers' Certificate delivered to the Trustee,
within ten business days of a request by the same, certifying that each such
contract, agreement, understanding, loan, advance and guarantee has been
approved by a majority of such Board. In the event that at the time of such
Payout, the condition set forth in clause (1) of the proviso of the preceding
sentence cannot be satisfied, such Restricted Subsidiary which is a Non-Core
Asset may seek to have a Person other than the Company or one of its Restricted
Subsidiaries pay in cash an amount to the Company such that, after taxes, such
amount, is greater than or equal to the Non-Core Asset Amount Due or the portion
of the Non-Core Asset Amount Due which would not have been permitted to be made
as a Restricted Payment by the Company; provided that such payment shall be
treated for purposes of this Section 4.21 as a cash return on the Investments
made in a Non-Core Asset and provided further that for all purposes under this
Indenture, such payment shall not be included in any calculation under clauses
(iii)(A) through (iii)(E) of the first paragraph of Section 4.07 of this
Indenture. To the extent that the Non-Core Asset Amount Due or any portion
thereof would have been permitted to be made as a Restricted Payment by the
Company and was not paid by another Person as permitted by the preceding
sentence, the Company shall be deemed to have made a Restricted Payment in the
amount of such Non-Core Asset Amount Due or portion thereof, as the case may be.

         Promptly after any Payout pursuant to the terms of this Section 4.21,
within ten Business Days of a request by the Trustee, the Company shall deliver
an Officers' Certificate to the Trustee setting forth the Investments made by
the Company or its

                                       64
<PAGE>   71

Restricted Subsidiaries in ETC or a Non-Core Asset, as the case may be, and
certifying that the requirements of this Section 4.21 have been satisfied in
connection with the making of such Payout.

         Notwithstanding anything contained in this Section 4.21, any
disposition of ETC or Non-Core Assets permitted pursuant to the 1999 EDBS Notes
Indentures and EDBS Exchange Indenture shall also be permitted pursuant to this
Indenture and shall not be considered a "Restricted Payment" or "Asset Sale" for
purposes of this Indenture.

SECTION 4.22. PAYMENTS FOR CONSENT.

         The Company shall not, and shall not permit any of its Subsidiaries to,
directly or indirectly, pay or cause to be paid any consideration, whether by
way of interest, fee or otherwise, to any holder of a Note for or as an
inducement to any consent, waiver or amendment of any of the terms or provisions
of this Indenture or the Notes unless such consideration is offered to be paid
or agreed to be paid to all holders of the Notes that consent, waive or agree to
amend in the time frame set forth in the solicitation documents relating to such
consent, waiver or agreement.

SECTION 5.01. MERGER, CONSOLIDATION, OR SALE OF ASSETS.

         The Company may not consolidate or merge with or into (whether or not
the Company is the surviving entity), or sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of its properties or assets in
one or more related transactions to, another Person unless (a) the Company is
the surviving Person or the Person formed by or surviving any such consolidation
or merger (if other than the Company) or to which such sale, assignment,
transfer, lease, conveyance or other disposition shall have been made is a
corporation organized or existing under the laws of the United States, any state
thereof or the District of Columbia; (b) the Person formed by or surviving any
such consolidation or merger (if other than the Company) or the Person to which
such sale, assignment, transfer, lease, conveyance or other disposition shall
have been made assumes all the obligations of the Company, pursuant to a
supplemental indenture in a form reasonably satisfactory to the Trustee, under
the Notes and this Indenture; (c) immediately after such transaction no Default
or Event of Default exists; and (d) the Company or the Person formed by or
surviving any such consolidation or merger (if other than the Company), or to
which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made (i) shall have Consolidated Net Worth immediately after the
transaction (but prior to any purchase accounting adjustments or accrual of
deferred tax liabilities resulting from the transaction) not less than the
Consolidated Net Worth of the Company immediately preceding the transaction and
(ii) would, at the time of such transaction after giving pro forma effect
thereto as if such transaction had occurred at the beginning of the applicable
four-quarter period, be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the Indebtedness to Cash Flow Ratio test set forth in
the first paragraph of Section 4.09.

                                       65
<PAGE>   72

         Notwithstanding the foregoing, the Company may merge with another
Person if (a) the Company is the surviving Person; (b) the consideration issued
or paid by the Company in such merger consists solely of Equity Interests (other
than Disqualified Stock) of the Company or Equity Interests of EchoStar; and (c)
immediately after giving effect to such merger, the Company's Indebtedness to
Cash Flow Ratio does not exceed the Company's Indebtedness to Cash Flow Ratio
immediately prior to such merger.

SECTION 5.02. SUCCESSOR CORPORATION SUBSTITUTED.

         Upon any consolidation or merger, or any sale, lease, conveyance or
other disposition of all or substantially all of the assets of the Company in
accordance with Section 5.01, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
lease, conveyance or other disposition is made shall succeed to, and be
substituted for (so that from and after the date of such consolidation, merger,
sale, lease, conveyance or other disposition, the provisions of this Indenture
referring to the Company shall refer instead to the successor corporation and
not to the Company), and may exercise every right and power of the Company under
this Indenture with the same effect as if such successor Person has been named
as the Company, herein.

                             DEFAULTS AND REMEDIES

SECTION 6.01. EVENTS OF DEFAULT.

                  (a) default for 30 days in the payment when due of interest on
         the Notes;

                  (b) default in the payment when due of principal of the Notes
         at maturity, upon repurchase, redemption or otherwise;

                  (c) failure to comply with the provisions of Section 4.10,

                  (d) default under Section 4.07 or Section 4.09, which default
         remains uncured for 30 days, or the breach of any representation or
         warranty, or the making of any untrue statement, in any certificate
         delivered by the Company pursuant to this Indenture;

                  (e) failure by the Company for 60 days after notice from the
         Trustee or the Holders of at least 25% in principal amount of the Notes
         then outstanding to comply with any of its other agreements in this
         Indenture or the Notes;

                  (f) default under any mortgage, indenture or instrument under
         which there may be issued or by which there may be secured or evidenced
         any

<PAGE>   73

         Indebtedness for money borrowed by the Company or any of its Restricted
         Subsidiaries (or the payment of which is guaranteed by the Company or
         any of its Restricted Subsidiaries), which default is caused by a
         failure to pay when due principal or interest on such Indebtedness
         within the grace period provided in such Indebtedness (a "Payment
         Default"), and the principal amount of any such Indebtedness, together
         with the principal amount of any other such Indebtedness under which
         there has been a Payment Default, aggregates $50 million or more;

                  (g) default under any mortgage, indenture or instrument under
         which there may be issued or by which there may be secured or evidenced
         any Indebtedness for money borrowed by the Company or any of its
         Restricted Subsidiaries (or the payment of which is guaranteed by the
         Company or any of its Restricted Subsidiaries), which default results
         in the acceleration of such Indebtedness prior to its express maturity
         and the principal amount of any such Indebtedness, together with the
         principal amount of any other such Indebtedness under which there has
         been a Payment Default or the maturity of which has been so
         accelerated, aggregates $50 million or more; provided that any
         acceleration (other than an acceleration which is the result of a
         Payment Default under clause (f) above) of Indebtedness under the
         Outstanding Deferred Payments in aggregate principal amount not to
         exceed $90 million shall be deemed not to constitute an acceleration
         pursuant to this clause (g);

                  (h) failure by the Company or any of its Restricted
         Subsidiaries to pay final judgments (other than any judgment as to
         which a reputable insurance company has accepted full liability)
         aggregating in excess of $50 million, which judgments are not stayed
         within 60 days after their entry; and

                  (i) EchoStar, the Company or any Significant Subsidiary of the
         Company pursuant to or within the meaning of Bankruptcy Law: (i)
         commences a voluntary case; (ii) consents to the entry of an order for
         relief against it in an involuntary case; (iii) consents to the
         appointment of a Custodian of it or for all or substantially all of its
         property; or (iv) makes a general assignment for the benefit of its
         creditors; and

                  (j) a court of competent jurisdiction enters an order or
         decree under any Bankruptcy Law that: (i) is for relief against
         EchoStar, the Company or any Significant Subsidiary of the Company in
         an involuntary case; (ii) appoints a Custodian of EchoStar, the Company
         or any Significant Subsidiary of the Company or for all or
         substantially all of the property of EchoStar, the Company or any
         Significant Subsidiary of the Company; or (iii) orders the liquidation
         of EchoStar or any Significant Subsidiary of the Company, and the order

SECTION 6.02. ACCELERATION.

         If an Event of Default (other than an Event of Default specified in
clause (i) or (j) of Section 6.01) occurs and is continuing, the Trustee by
notice to the Company, or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes by written notice to the Company and the
Trustee, may declare all the Notes to be due and payable immediately. In the
case of an Event of Default specified in clause (i) or (j) of Section 6.01, with
respect to EchoStar, the Company or any Significant Subsidiary of the Company,
all outstanding Notes shall become and be immediately due and payable without
further action or notice. Holders of the Notes may not enforce this Indenture or
the Notes except as provided in this Indenture. The Trustee may withhold from
Holders of the Notes notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal or
interest) if it determines that withholding notice is in such Holders' interest.
The Holders of a majority in aggregate principal amount of the then outstanding
Notes by written notice to the Trustee may on behalf of all of the Holders
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default
(except nonpayment of principal, interest or premium that has become due solely
because of the acceleration) have been cured or waived.

         In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company or its
Subsidiaries with the intention of avoiding payment of the premium that the
Company would have had to pay if the Company then had elected to redeem the
Notes pursuant to Section 3.07, an equivalent premium shall also become and be
immediately due and payable to the extent permitted by law.

         All powers of the Trustee under this Indenture will be subject to
applicable provisions of the Communications Act, including without limitation,
the requirements of prior approval for de facto or de jure transfer of control
or assignment of Title III licenses.

SECTION 6.03. OTHER REMEDIES.

         If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest on the Notes or to enforce the performance of any provision of the
Notes and this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Notes or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder of a Note in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

SECTION 6.04. WAIVER OF PAST DEFAULTS.

         Holders of not less than a majority in aggregate principal amount of
Notes then outstanding, by notice to the Trustee, may on behalf of the Holders
of all of the Notes waive an existing Default or Event of Default and its
consequences under this Indenture, except a continuing Default or Event of
Default in the payment of the principal of, premium, if any, or interest on, the
Notes. 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 impair any right consequent thereon.

SECTION 6.05. CONTROL BY MAJORITY.

         Holders of a majority in principal amount of the then outstanding Notes
may direct the time, method and place of conducting any proceeding for
exercising any remedy available to the Trustee or exercising any trust or power
conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with the law or this Indenture that the Trustee determines may be
unduly prejudicial to the rights of other Holders of Notes or that may involve
the Trustee in personal liability.

SECTION 6.06. LIMITATION ON SUITS.

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

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

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

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

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

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

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

                                       69
<PAGE>   76

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

         Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium, if any, and interest
on the Note, on or after the respective due dates expressed in the Note, or to
bring suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of the Holder of
the Note.

SECTION 6.08. COLLECTION SUIT BY TRUSTEE.

         If an Event of Default specified in Section 6.01(a) or (b) occurs and
is continuing, the Trustee is authorized to recover judgment in its own name and
as trustee of an express trust against the Company for the whole amount of
principal of, premium, if any, and interest remaining unpaid on the Notes and
interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

SECTION 6.09. TRUSTEE MAY FILE PROOFS OF CLAIM.

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

SECTION 6.10. PRIORITIES.

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

                  First: to the Trustee, its agents and attorneys for amounts
         due under Section 7.07, including payment of all compensation, expense
         and liabilities incurred, and all advances made, by the Trustee and the
         costs and expenses of collection;

                  Second: to Holders of Notes for amounts due and unpaid on the

         respectively; and

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

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

SECTION 6.11. UNDERTAKING FOR COSTS.

         In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in the suit, having due regard to
the merits and good faith of the claims or defenses made by the party litigant.
This Section does not apply to a suit by the Trustee, a suit by a Holder of a
Note pursuant to Section 6.07, or a suit by Holders of more than 10% in
principal amount of the then outstanding Notes.

                                    TRUSTEE

SECTION 7.01. DUTIES OF TRUSTEE.

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

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

                  (i) the duties of the Trustee shall be determined solely by
         the express provisions of this Indenture and the Trustee need perform
         only those duties that are specifically set forth in this Indenture and
         no others, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

                                       71
<PAGE>   78

                  (ii) in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements of
         this Indenture. However, the Trustee shall examine the certificates and
         opinions to determine whether or not they conform to the requirements
         of this Indenture.

         (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

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

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

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

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

         (e) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or incur any liability. The Trustee shall be under no
obligation to exercise any of its rights and powers under this Indenture at the
request of any Holders of Notes, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to the Trustee against any loss,
liability or expense.

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

SECTION 7.02. RIGHTS OF TRUSTEE.

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

         (b) Before the Trustee acts or refrains from acting, it may require an
Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such Officers' Certificate or Opinion of Counsel. The Trustee may consult with
counsel and the advice of such counsel or any Opinion of Counsel shall be full
and complete authorization and protection from liability in respect of any
action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.

                                       72
<PAGE>   79

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

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

         (e) Unless otherwise specifically provided in this Indenture, any
demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

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

         (g) Except with respect to Section 4.01, the Trustee shall have no duty
to inquire as to the performance of the Company's covenants in Article 4. In

Event of Default except (i) any Event of Default occurring pursuant to Sections
4.01, 6.01(a) and 6.01(b) or (ii) any Default or Event of Default of which the
Trustee shall have received written notification or obtained actual knowledge.

         (h) Delivery of reports, information and documents to the Trustee under
Section 4.03 is for informational purposes only and the Trustee's receipt of the
foregoing shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the
Company's compliance with any of its covenants hereunder.

SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

         The Trustee in its individual or any other capacity may become the
owner or pledgee of Notes and may otherwise deal with the Company or any
Affiliate of the Company with the same rights it would have if it were not
Trustee. However, in the event that the Trustee acquires any conflicting
interest it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue as Trustee (if any of the Notes are registered pursuant
to the Securities Act), or resign. Any Agent may do the same with like rights
and duties. The Trustee is also subject to Sections 7.10 and 7.11.

SECTION 7.04. TRUSTEES DISCLAIMER.

         The Trustee shall not be responsible for and makes no representation as
to the validity or adequacy of this Indenture or the Notes, it shall not be
accountable for the Company's use of the proceeds from the Notes or any money
paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital

                                       73
<PAGE>   80

herein or any statement in the Notes or any other document in connection with
the sale of the Notes or pursuant to this Indenture other than its certificate
of authentication.

SECTION 7.05. NOTICE OF DEFAULTS.

         If a Default or Event of Default occurs and is continuing and if it is
known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders
of Notes a notice of the Default or Event of Default within 90 days after it
occurs. Except in the case of a Default or Event of Default in payment of
principal of, premium, if any, or interest on any Note, the Trustee may withhold
the notice if and so long as a committee of its Responsible Officers in good
faith determines that withholding the notice is in the interests of the Holders
of the Notes.

SECTION 7.06. REPORTS BY TRUSTEE TO HOLDERS OF THE NOTES.

         Within 60 days after each May 15 beginning with the May 15 following
the date of this Indenture, the Trustee shall mail to the Holders of the Notes a
brief report dated as of such reporting date that complies with TIA Section
313(a) (but if no event described in TIA Section 313(a) has occurred within the
twelve months preceding the reporting date, no report need be transmitted). The
Trustee also shall comply with TIA Section 313(b). The Trustee shall also
transmit by mail all reports as required by TIA Section 313(c).

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

SECTION 7.07. COMPENSATION AND INDEMNITY.

         The Company shall pay to the Trustee from time to time reasonable
compensation for its acceptance of this Indenture and services hereunder. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee promptly
upon request for all reasonable disbursements, advances and expenses incurred or
made by it in addition to the compensation for its services. Such expenses shall
include the reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel.

         The Company shall indemnify the Trustee against any and all losses,
liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, except any such
loss, liability or expense as may be attributable to the gross negligence,
willful misconduct or bad faith of the Trustee. The Trustee shall notify the
Company promptly of any claim for which it may seek indemnity. Failure by the
Trustee to so notify the Company shall not relieve the Company of its
obligations hereunder. The Company shall defend the claim and the Trustee shall
cooperate in the defense. The Trustee may have separate counsel and the Company
shall pay the reasonable fees and

                                       74
<PAGE>   81

expenses of such counsel. The Company need not pay for any settlement made
without its consent, which consent shall not be unreasonably withheld.

         The obligations of the Company under this Section 7.07 shall survive
the satisfaction and discharge of this Indenture.

         To secure the Company's payment obligations in this Section, the
Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal and
interest on particular Notes. Such Lien shall survive the satisfaction and
discharge of this Indenture.

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

SECTION 7.08. REPLACEMENT OF TRUSTEE.

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

         The Trustee may resign in writing at any time and be discharged from
the trust hereby created by so notifying the Company and obtaining the prior
written approval of the FCC, if so required by the Communications Act, including
Section 310(d) and the rules and regulations promulgated thereunder. The Holders
of at least a majority in principal amount of the then outstanding Notes may
remove the Trustee by so notifying the Trustee and the Company in writing. The
Company may remove the Trustee (subject to the prior written approval of the
FCC, if required by the Communications Act, including Section 310(d), and the
rules and regulations promulgated thereunder) if:

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

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

                  (c) the Trustee is no longer in compliance with the foreign
         ownership provisions of Section 310 of the Communications Act and the
         rules and regulations promulgated thereunder.

                  (d) a Custodian or public officer takes charge of the Trustee
         or its property; or

                  (e) the Trustee becomes incapable of acting.

         If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in

                                       75
<PAGE>   82

principal amount of the then outstanding Notes may appoint a successor Trustee
to replace the successor Trustee appointed by the Company.

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

         If the Trustee after written request by any Holder of a Note who has
been a Holder of a Note for at least six months fails to comply with
Section 7.10, such Holder of a Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

         A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums
owing to the Trustee hereunder have been paid and subject to the Lien provided
for in Section 7.07. Notwithstanding replacement of the Trustee pursuant to this
Section 7.08, the Company's obligations under Section 7.07 shall continue for
the benefit of the retiring Trustee.

SECTION 7.09. SUCCESSOR TRUSTEE BY MERGER, ETC.

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

SECTION 7.10. ELIGIBILITY; DISQUALIFICATION.

         There shall at all times be a Trustee hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America or of any state thereof authorized under such laws to exercise corporate
trustee power, shall be subject to supervision or examination by federal or
state authority and shall have a combined capital and surplus of at least $25
million as set forth in its most recent published annual report of condition.

         This Indenture shall always have a Trustee who satisfies the
requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to
TIA Section 310(b).

SECTION 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

         The Trustee is subject to TIA Section 311(a), excluding any creditor
relationship listed in TIA Section 311(b). A Trustee who has resigned or been
removed shall be subject to TIA Section 311(a) to the extent indicated therein.

                    LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.01. OPTION TO EFFECT LEGAL DEFEASANCE OR COVENANT DEFEASANCE.

         The Company may, at the option of its Board of Directors evidenced by a
resolution set forth in an Officers' Certificate, at any time, with respect to
the Notes, elect to have either Section 8.02 or 8.03 be applied to all
outstanding Notes upon compliance with the conditions set forth below in this
Article 8.

SECTION 8.02. LEGAL DEFEASANCE AND DISCHARGE.

         Upon the Company's exercise under Section 8.01 of the option applicable
to this Section 8.02, 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 below are satisfied (hereinafter, "Legal Defeasance"). For this
purpose, such Legal Defeasance means that the Company shall be deemed to have
paid and discharged the entire Indebtedness represented by the outstanding
Notes, which shall thereafter be deemed to be "outstanding" only for the
purposes of Section 8.05 and the other Sections of this Indenture referred to in
(a) and (b) below, and to have satisfied all its other obligations under such
Notes and this Indenture (and the Trustee, on demand of and 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 payments in
respect of the principal of, premium, if any, and interest on such Notes when
such payments are due, or on the redemption date, as the case may be, (b) the
Company's obligations with respect to such Notes under Sections 2.05, 2.07,
2.08, 2.10, 2.11 and 4.02, (c) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and the Company's obligations in connection therewith
and (d) this Article 8. Subject to compliance with this Article 8, the Company
may exercise its option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 with respect to the Notes.

SECTION 8.03. COVENANT DEFEASANCE.

         Upon the Company's exercise under Section 8.01 of the option applicable
to this Section 8.03, the Company shall be released from its obligations under
the covenants contained in Sections 3.09, 4.03, 4.04, 4.07, 4.08, 4.09, 4.10,
4.11, 4.12, 4.15, 4.16, 4.17, 4.19, 4.20, 4.21 and 5.01 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 "outstanding" for the purposes of any direction, waiver, consent
or declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants, but shall continue to be deemed "outstanding"
for all other purposes hereunder (it being understood that such Notes shall not
be deemed outstanding for GAAP). 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

                                       77
<PAGE>   84

document and such omission to comply shall not constitute a Default or an Event
of Default under Section 6.01(c), but, except as specified above, the remainder
of this Indenture and such Notes shall be unaffected thereby. In addition, upon
the Company's exercise under Section 8.01 of the option applicable to this
Section 8.03, Sections 6.01(c) through 6.01(h) shall not constitute Events of
Default.

SECTION 8.04. CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

         The following shall be the conditions to the application of either
Section 8.02 or Section 8.03 to the outstanding Notes:

                  (a) The Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 7.10 who shall agree to comply with the
         provisions of this Article 8 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, (i) cash in U.S. Dollars, (ii) non-callable Government
         Securities 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,
         cash in U.S. Dollars, or (iii) a combination thereof, in such amounts,
         as will be sufficient in each case, in the opinion of a nationally
         recognized firm of independent public accountants expressed in a
         written certification thereof delivered to the Trustee, to pay and
         discharge and which shall be applied by the Trustee (or other
         qualifying trustee) to pay and discharge (A) the principal of, premium,
         if any, and interest on the outstanding Notes on the stated maturity or
         on the applicable redemption date, as the case may be, of such
         principal or installment of principal, premium, if any, or interest and
         (B) any mandatory sinking fund payments or analogous payments
         applicable to the outstanding Notes 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 such money or the proceeds of such non-callable
         Government Securities to said payments with respect to the Notes;

                  (b) In the case of an election under Section 8.02, the Company
         shall have delivered to the Trustee an Opinion of Counsel in the United
         States reasonably satisfactory to the Trustee confirming that (i) the
         Company has received from, or there has been published by, the Internal
         Revenue Service a ruling or (ii) since the date hereof, 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 Legal
         Defeasance and will be subject to federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such Legal Defeasance had not occurred;

                  (c) In the case of an election under Section 8.03, the Company
         shall have delivered to the Trustee an Opinion of Counsel in the United
         States reasonably satisfactory to the Trustee to the effect that the
         Holders of the

                                       78
<PAGE>   85

         outstanding Notes will not recognize income, gain or loss for federal
         income tax purposes as a result of such Covenant Defeasance and will be
         subject to federal income tax on the same amounts, in the same manner
         and at the same times as would have been the case if such Covenant
         Defeasance had not occurred;

                  (d) No Default or Event of Default with respect to the Notes
         shall have occurred and be continuing on the date of such deposit or,
         in so far as Section 6.01(i) or 6.01(j) is concerned, at any time in
         the period ending on the 91st day after the date of such deposit (it
         being understood that this condition shall not be deemed satisfied
         until the expiration of such period);

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

                  (f) The Company shall have delivered to the Trustee an
         Officers' Certificate stating that the deposit made by the Company
         pursuant to its election under Section 8.02 or 8.03 was not made by the
         Company with the intent of preferring the Holders over any other
         creditors of the Company or with the intent of defeating, hindering,
         delaying or defrauding creditors of the Company or others; and

                  (g) The Company shall have delivered to the Trustee an
         Officers' Certificate and an Opinion of Counsel in the United States,
         each stating that all conditions precedent provided for relating to
         either the Legal Defeasance under Section 8.02 or the Covenant
         Defeasance under Section 8.03 (as the case may be) have been complied
         with as contemplated by this Section 8.04.

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

         Subject to Section 8.06, all money and Government Securities (including
the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the "Trustee") pursuant to
Section 8.04 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 Paying Agent) as the Trustee may determine, to
the Holders of such Notes of all sums due and to become due thereon in respect
of principal, premium, 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 cash or Government Securities
deposited pursuant to Section 8.04 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.

                                       79
<PAGE>   86

         Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or Government Securities held by it as provided in Section
8.04 which, in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee (which may be the opinion delivered under Section 8.04(a)), are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.06. REPAYMENT TO COMPANY.

         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, premium, if any,
or interest on any Note and remaining unclaimed for two years after such
principal, and premium, if any, or interest has become due and payable shall be
paid to the Company on its request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Note shall thereafter, as a
secured 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 trustees thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in the New York Times and The Wall Street Journal (national
edition), notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company.

SECTION 8.07. REINSTATEMENT.

         If the Trustee or Paying Agent is unable to apply any United States
Dollars or Government Notes in accordance with Section 8.02 or 8.03, as the case
may be, by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, then
the Company's obligations under this Indenture and the Notes shall be revived
and reinstated as though no deposit had occurred pursuant to Section 8.02 or
8.03 until such time as the Trustee or Paying Agent is permitted to apply all
such money in accordance with Section 8.02 or 8.03, as the case may be;
provided, however, that, if the Company makes any payment of principal of,
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.

                        AMENDMENT, SUPPLEMENT AND WAIVER

SECTION 9.01. WITHOUT CONSENT OF HOLDERS OF NOTES.

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

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

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

                  (c) to provide for the assumption of the Company's obligations
         to the Holders of the Notes in the case of a merger or consolidation
         pursuant to Article 5;

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

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

         Upon the request of the Company accompanied by a resolution of the
Board of Directors of the Company and upon receipt by the Trustee of the
documents described in Section 10.04, the Trustee shall join with the Company in
the execution of any amended or supplemental Indenture authorized or permitted
by the terms of this Indenture and to make any further appropriate agreements
and stipulations which may be therein contained, but the Trustee shall not be
obligated to enter into such amended or supplemental Indenture which affects its
own rights, duties or immunities under this Indenture or otherwise.

SECTION 9.02. WITH CONSENT OF HOLDERS OF NOTES.

         The Company and the Trustee may amend or supplement this Indenture and
the Notes or any amended or supplemental Indenture with the written consent of
the Holders of Notes of at least a majority in aggregate principal amount of the
Notes then outstanding (including consents obtained in connection with a tender
offer or exchange offer for the Notes), and any existing Default and its
consequences or compliance with any provision of this Indenture or the Notes may
be waived with the consent of the Holders of a majority in principal amount of
the then outstanding Notes (including consents obtained in connection with a
tender offer or exchange offer for the Notes). Notwithstanding the foregoing,
(a) Sections 3.09, 4.10, 4.13 and 4.15 of this Indenture (including, in each
case, the related definitions) may not be amended or waived without the written
consent of at least 66-2/3% in principal amount of the Notes then outstanding
(including consents obtained in connection with a tender offer or exchange offer
for the Notes) and (b) without the consent of

                                       81
<PAGE>   88

each Holder affected, an amendment or waiver may not (with respect to any Notes
held by a non-consenting Holder of Notes):

                  (i) reduce the aggregate principal amount of Notes whose
         Holders must consent to an amendment, supplement or waiver;

                  (ii) reduce the principal of or change the fixed maturity of
         any Note or alter the provisions with respect to the redemption of the
         Notes;

                  (iii) reduce the rate of or change the time for payment of
         interest on any Note;

                  (iv) waive a Default or Event of Default in the payment of
         principal of or premium, if any, or interest on the Notes (except a
         rescission of acceleration of the Notes by the Holders of at least a
         majority in aggregate principal amount of the then outstanding Notes
         and a waiver of the payment default that resulted from such
         acceleration);

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

                  (vi) make any change in the provisions of this Indenture
         relating to waivers of past Defaults or the rights of Holders of Notes
         to receive payments of principal of or interest on the Notes;

                  (vii) waive a redemption payment or mandatory redemption with
         respect to any Note; or

                  (viii) make any change in the foregoing amendment and waiver
         provisions.

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

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

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

                                       82
<PAGE>   89

waiver. Subject to Sections 6.04 and 6.07, the Holders of a majority in
aggregate principal amount of the Notes then outstanding may waive compliance in
a particular instance by the Company with any provision of this Indenture or the
Notes.

SECTION 9.03. COMPLIANCE WITH TRUST INDENTURE ACT.

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

SECTION 9.04. REVOCATION AND EFFECT OF CONSENTS.

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

         The Company may fix a record date for determining which Holders of the
Notes must consent to such amendment, supplement or waiver. If the Company fixes
a record date, the record date shall be fixed at (i) the later of 30 days prior
to the first solicitation of such consent or the date of the most recent list of
Holders of Notes furnished to the Trustee prior to such solicitation pursuant to
Section 2.05 or (ii) such other date as the Company shall designate.

SECTION 9.05. NOTATION ON OR EXCHANGE OF NOTES.

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

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

SECTION 9.06.  TRUSTEE TO SIGN AMENDMENTS, ETC.

         The Trustee shall sign any amended or supplemental Indenture authorized
pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. The Company
may not sign any amended or supplemental Indenture until its Board of Directors
approves it.

         If a notice or communication is mailed in the manner provided above
within the time prescribed, it is duly given, whether or not the addressee
receives it.

         If the Company mails a notice or communication to Holders of Notes, it

         Holders of the Notes may communicate pursuant to TIA Section 312(b)
with other Holders of Notes with respect to their rights under this Indenture or
the Notes. The Company, the Trustee, the Registrar and anyone else shall have

SECTION 10.04. CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

         Upon any request or application by the Company to the Trustee to take
any action under this Indenture, the Company shall furnish to the Trustee:

         satisfactory to the Trustee stating that, in the opinion of the
         signers, all conditions precedent and covenants, if any, provided for

         and

         (b) an Opinion of Counsel in form and substance reasonably satisfactory
         to the Trustee stating that, in the opinion of such counsel, all such
         conditions precedent and covenants have been satisfied.

         read such covenant or condition;

obligations of the Company, and any of its Affiliates under the Notes, or this
Indenture or for any claim based on, in respect of, or by reason of, such
obligations or their creation. Each Holder of the Notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to
waive liabilities under the federal securities laws and it is the view of the
SEC that such waiver is against public policy.

                                 (Back of Note)

             Capitalized terms used herein have the meanings assigned to them in
the Indenture (as defined below) unless otherwise indicated

         (a) Interest. EchoStar Broadband Corporation, a Colorado corporation
(the "Company") promises to pay interest on the principal amount of this Note at
the rate and in the manner specified below. Interest will accrue at 10 3/8% per
annum and will be payable semi-annually in cash on each April 1 and October 1,
commencing April 1, 2001, or if any such day is not a Business Day on the next
succeeding Business Day (each an "Interest Payment Date") to Holders of record
of the Notes at the close of business on the immediately preceding March 15 and
September 15, whether or not a Business Day. Interest will be computed on the
basis of a 360-day year consisting of twelve 30-day months. Interest shall
accrue from the most recent date to which interest has been paid or, if no
interest has been paid, from September 25, 2000. To the extent lawful, the
Company shall pay interest on overdue principal at the rate of the then
applicable interest rate on the Notes; it shall pay interest on overdue
installments of interest (without regard to any applicable grace periods) at the
same rate to the extent lawful. In addition, Holders may be entitled to the
benefits of certain provisions of the Registration Rights Agreement.

         (b) 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 record date next preceding the Interest Payment
Date, even if such Notes are canceled after such record date and on or before
such Interest Payment Date. The Holder hereof must surrender this Note 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. The Notes will be payable both
as to principal and interest at the office or agency of the Company maintained
for such purpose or, at the option of the Company, payment of interest may be
made by check mailed to the Holders of Notes at their respective addresses set
forth in the register of Holders of Notes. Unless otherwise designated by the
Company, the Company's office or agency will be the office of the Trustee
maintained for such purpose.

         (c) Paying Agent and Registrar. Initially, the Trustee will act as
Paying Agent and Registrar. The Company may change any Paying Agent, Registrar
or co-registrar without prior notice to any Holder of a Note. The Company may
act in any such capacity.

         (d) Indenture. The Company issued the Notes under an Indenture, dated
as of September 25, 2000 (the "Indenture"), among 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, as amended (15
U.S. Code Section 77aaa-77bbbb), as in effect on the date of the Indenture. The
Notes are subject to all such terms, and Holders of Notes are referred to the
Indenture and such act for a statement of such terms. The terms of the Indenture
shall govern any inconsistencies between the Indenture and the Notes. The Notes
are unsecured obligations of the Company.

         (e) Optional Redemption. Except as provided in the next paragraph, the
Notes will not be redeemable at the Company's option prior to October 1, 2004.
Thereafter, the

                                      A-2
<PAGE>   97

Notes will be subject to redemption at the option of the Company, in whole or in
part, upon not less than 30 nor more than 60 days' notice, at the redemption
prices (expressed as percentages of principal amount) set forth below, together
with accrued and unpaid interest thereon to the applicable redemption date, if
redeemed during the 12-month period beginning on October 1 of the years
indicated below:

<TABLE>
<CAPTION>
YEAR                                                            PERCENTAGE
----                                                            ----------
<S>                                                           <C>
2004 ..........................................................  105.188%
2005 ..........................................................  102.594%
2006 ..........................................................  100.000%
</TABLE>

      Notwithstanding the foregoing, at any time prior to October 1, 2003, the
Company may redeem up to 35% of the aggregate principal amount of the Notes
outstanding at a redemption price equal to 110.375% of the principal amount
thereof on the repurchase date, together with accrued and unpaid interest to
such repurchase date, with the net cash proceeds of one or more public or
private sales (including sales to EchoStar, regardless of whether EchoStar
obtained such funds from an offering of Equity Interests or Indebtedness of
EchoStar or otherwise) of Equity Interests (other than Disqualified Stock) of
the Company (other than proceeds from a sale to any Subsidiary of the Company or
any employee benefit plan in which the Company or any of its Subsidiaries
participates); provided that: (a) at least 65% in aggregate principal amount of
the Notes originally issued remain outstanding immediately after the occurrence
of such redemption; and (b) the sale of such Equity Interests is made in
compliance with the terms of the Indenture.

         (f) Mandatory Redemption. Under the circumstances described in Section
3.08 of the Indenture, the Company will be required to redeem all, but not less
than all, of the Notes at a redemption price equal to 100% of the principal
amount thereof, together with accrued and unpaid interest to such a redemption
date.

         (g) Repurchase at Option of Holder. Upon the occurrence of a Change of
Control, the Company will be required to offer to purchase on the Change of
Control Payment Date all outstanding Notes at a purchase price equal to 101% of
the aggregate principal amount thereof, together with accrued and unpaid
interest thereon to the date of purchase. Holders of Notes that are subject to
an offer to purchase will receive a Change of Control Offer from the Company
prior to any related Change of Control Payment Date and may elect to have such
Notes purchased by completing the form entitled "Option of Holder to Elect
Purchase" appearing below.

                                      A-3
<PAGE>   98

      When the cumulative amount of Excess Proceeds that have not been applied
in accordance with Section 4.10 (Asset Sales) and 4.16 (Maintenance of
Insurance) or Section 3.09 (Offer to Purchase By Application of Excess Proceeds)
of the Indenture, exceeds $25 million, the Company will be required to offer to
purchase the maximum principal amount of Notes that may be purchased out of such
Excess Proceeds at an offer price in cash in an amount equal to 101% of the
principal amount thereof, together with accrued and unpaid interest thereon to
the date of purchase. To the extent the Company or a Restricted Subsidiary is
required under the terms of Indebtedness of the Company or such Restricted
Subsidiary which is pari passu with, or (in the case of any secured
Indebtedness) senior with respect to such collateral to, the Notes with any
proceeds which constitute Excess Proceeds under the Indenture, the Company shall
make a pro rata offer to the holders of all other pari passu Indebtedness
(including the Notes) with such proceeds. If the aggregate principal amount of
Notes and other pari passu Indebtedness surrendered by holders thereof exceeds
the amount of such Excess Proceeds, the Trustee shall select the Notes and other
pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes
that are subject to an offer to purchase will receive a Excess Proceeds Offer
from the Company prior to any related Purchase Payment Date and may elect to
have such Notes purchased by completing the form entitled "Option of Holder to
Elect Purchase" appearing below.

      (h) Notice of Redemption. Notice of redemption shall be mailed at least 30
days but not more than 60 (or at least 3 days but not more than 10 days notice
with respect to a redemption pursuant to Subsection (f) above) days before the
redemption date to each Holder whose Notes are to be redeemed at its registered
address. Notes may be redeemed in part but only in whole multiples of $1,000,
unless all of the Notes held by a Holder of Notes are to be redeemed. On and
after the redemption date, interest ceases to accrue on Notes or portions of
them called for redemption unless the Company fails to redeem such Notes or such
portions thereof.

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

      (j) Persons Deemed Owners. Prior to due presentment to the Trustee for
registration of the transfer of this Note, the Trustee, any Agent and the
Company may deem and treat the Person in whose name this Note is registered as
its absolute owner for the purpose of receiving payment of principal of,
premium, if any, and interest on this Note and for all other purposes
whatsoever, whether or not this Note is overdue, and neither the Trustee, any
Agent nor the Company shall be affected by notice to the contrary. The
registered Holder of a Note shall be treated as its owner for all purposes.

      (k) Amendments, Supplement and Waivers. Subject to certain exceptions, the
Indenture or Notes may be amended or supplemented with the consent of the
Holders of at least a majority in principal amount of the then outstanding Notes
(including consents

                                      A-4
<PAGE>   99

obtained in connection with a tender offer or exchange offer for the Notes), and
any existing default or compliance with any provision of the Indenture or the
Notes may be waived with the consent of the Holders of a majority in principal
amount of the then outstanding Notes (including consents obtained in connection
with a tender offer or exchange offer for the Notes). Notwithstanding the
foregoing, (a) Sections 3.09 (Offer to Purchase by Application of Excess
Proceeds), 4.10 (Asset Sales), 4.13 (Exchange of Notes for EDBS Exchange Notes)
and 4.15 (Offer to Repurchase Upon Change in Control) of the Indenture
(including, in each case, the related definitions) may not be amended or waived
without the written consent of at least 66 2/3% in principal amount of the Notes
then outstanding (including consents obtained in connection with a tender offer
or exchange offer for the Notes) and (b) without the consent of each Holder
affected, an amendment or waiver may not (with respect to any Notes held by a
non-consenting Holder of Notes) reduce the principal amount of Notes whose
Holders must consent to an amendment, supplement or waiver; reduce the principal
of or change the fixed maturity of any Note or alter the provisions with respect
to the redemption of the Notes; reduce the rate of or change the time for
payment of interest on any Note; waive a Default or Event of Default in the
payment of principal of or premium, if any, or interest on the Notes (except a
rescission of acceleration of the Notes by the Holders of at least a majority in
aggregate principal amount of the then outstanding Notes and a waiver of the
payment default that resulted from such acceleration); make any Note payable in
money other than that stated in the Notes; make any change in the provisions of
the Indenture relating to waivers of past Defaults or the rights of Holders of
Notes to receive payments of principal of or interest on the Notes; waive a
redemption payment or mandatory redemption with respect to any Note; or make any
change in the foregoing amendment and waiver provisions. Notwithstanding the
foregoing, without the consent of any Holder of a Note, the Indenture or the
Notes may be amended or supplemented to cure any ambiguity, defect or
inconsistency; to provide for uncertificated Notes in addition to or in place of
certificated Notes; to provide for the assumption of the Company's obligations
to the Holders of the Notes in case of a merger or consolidation; to make any
change that would provide any additional rights or benefits to the Holders of
the Notes or that does not adversely affect the legal rights under the Indenture
of any such Holder; or to comply with the requirements of the SEC in order to
effect or maintain the qualification of the Indenture under the Trust Indenture
Act.

      (l) Defaults and Remedies. Each of the following constitutes an Event of
Default:

          (a) default for 30 days in the payment when due of interest on the
      Notes;

          (b) default in payment when due of principal of the Notes at maturity,
      upon repurchase, redemption or otherwise;

          (c) failure to comply with the provisions described under Section 4.15
      (Offer to Purchase Upon Change in Control), Section 4.16 (Maintenance of
      Insurance), Section 4.11 (Limitation on Transactions with Affiliates),
      Section 4.10 (Asset Sales) of the Indenture, or Section 4.13 (Exchange of
      Notes for EDBS Exchange Notes);

          (d) default under the provisions described under Section 4.07
      (Limitation on Restricted Payments) or Section 4.09 (Incurrence of
      Indebtedness) of the Indenture which default remains uncured for 30 days,
      or the breach of any representation

                                      A-5
<PAGE>   100

      or warranty, or the making of any untrue statement, in any certificate
      delivered by the Company pursuant to the Indenture;

          (e) failure by the Company for 60 days after notice from the Trustee
      or the holders of at least 25% in principal amount of the then outstanding
      Notes to comply with any of its other agreements in the Indenture or the
      Notes;

          (f) default under any mortgage, indenture or instrument under which
      there may be issued or by which there may be secured or evidenced any
      Indebtedness for money borrowed by the Company or any of its Restricted
      Subsidiaries (or the payment of which is guaranteed by the Company or any
      of its Restricted Subsidiaries), which default is caused by a failure to
      pay when due principal or interest on such Indebtedness within the grace
      period provided in such Indebtedness (a "Payment Default"), and the
      principal amount of any such Indebtedness, together with the principal
      amount of any other such Indebtedness under which there has been a Payment
      Default, aggregates $50 million or more;

          (g) default under any mortgage, indenture or instrument under which
      there may be issued or by which there may be secured or evidenced any
      Indebtedness for money borrowed by the Company or any of its Restricted
      Subsidiaries (or the payment of which is guaranteed by the Company or any
      of its Restricted Subsidiaries), which default results in the acceleration
      of such Indebtedness prior to its express maturity and the principal
      amount of any such Indebtedness, together with the principal amount of any
      other such Indebtedness under which there has been a Payment Default or
      the maturity of which has been so accelerated, aggregates $50 million or
      more; provided that any acceleration (other than an acceleration which is
      the result of a Payment Default under clause (f) above) of Indebtedness
      under the Outstanding Deferred Payments in aggregate principal amount not
      to exceed $90 million shall be deemed not to constitute an acceleration
      pursuant to this clause (g);

          (h) failure by the Company or any of its Restricted Subsidiaries to
      pay final judgments (other than any judgment as to which a reputable
      insurance company has accepted full liability) aggregating in excess of
      $50 million, which judgments are not stayed within 60 days after their
      entry; and

          (i) certain events of bankruptcy or insolvency with respect to
      EchoStar, the Company or certain of the Company's Subsidiaries (including
      the filing of a voluntary case, the consent to an order of relief in an
      involuntary case, the consent to the appointment of a custodian, a general
      assignment for the benefit of creditors or an order of a court for relief
      in an involuntary case, appointing a custodian or ordering liquidation,
      which order remains unstayed for 60 days).

      If any Event of Default occurs and is continuing, the Trustee or the
holders of at least 25% in principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately (plus, in the case of an
Event of Default that is the result of an action by the Company or any of its
Subsidiaries intended to avoid restrictions on or premiums related to
redemptions of the Notes contained in the Indenture or the Notes, an amount of
premium that would have been applicable pursuant to the Notes or as set forth in
the Indenture). Notwithstanding the foregoing, in the case of an Event of
Default arising from the events of bankruptcy or insolvency with respect to the
Company or any of its

                                      A-6
<PAGE>   101

Subsidiaries described in (i) above, all outstanding Notes will become due and
payable without further action or notice. Holders of the Notes may not enforce
the Indenture or the Notes except as provided in the Indenture. Subject to
certain limitations, holders of a majority in principal amount of the then
outstanding Notes may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from holders of the Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in such holders' interest.

      The holders of a majority in aggregate principal amount of the then
outstanding Notes, by notice to the Trustee, may on behalf of the holders of all
of the Notes waive any existing Default or Event of Default and its consequences
under the Indenture, except a continuing Default or Event of Default in the
payment of interest or premium on, or principal of, the Notes.

      The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon
becoming aware of any Default or Event of Default to deliver to the Trustee a
statement specifying such Default or Event of Default.

      All powers of the Trustee under the Indenture will be subject to
applicable provisions of the Communications Act, including without limitation,
the requirements of prior approval for de facto or de jure transfer of control
or assignment of Title III licenses.

      (m) Trustee Dealings with Company. The Trustee under the Indenture, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with
the Company or its Affiliates, as if it were not Trustee; however, if the
Trustee acquires any conflicting interest it must eliminate such conflict within
90 days, apply to the SEC for permission to continue as Trustee or resign.

      (n) No Personal Liabilities of Directors, Officers, Employees,
Incorporators and Stockholders. No director, officer, employee, incorporator or
stockholder of the Company or any of its Affiliates, as such, shall have any
liability for any obligations of the Company or any of its Affiliates under this
Note or the Indenture or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each Holder of the Notes by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.

      (o) Exchange for EDBS Exchange Notes. Under the circumstances described in
Section 4.13 of the Indenture, EDBS will be required to make an offer to
exchange the EDBS Exchange Notes for the Notes.

      (p) Obligation Solely of the Company. The Holder of this Note acknowledges
this Note is an obligation solely of the Company and prior to the consummation
of the EDBS Exchange Offer such Holder shall have no claim to receive the EDBS
Exchange Notes.

      (q) Authentication. This Note shall not be valid until authenticated by
the manual signature of the Trustee or an authenticating agent.

Committee on Uniform Note Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and has directed the Trustee to use

representation is made as to the accuracy of such numbers either as printed on

all necessary filings, if any, in connection with the registration and
qualification of the Exchange Notes to be made under the Blue Sky laws of such
jurisdictions as are necessary to permit Consummation of the Exchange Offer, and
(iv) upon the effectiveness of such Exchange Offer Registration Statement,
commence and Consummate the Exchange Offer such that the Exchange Offer is
Consummated not later than the 295th day after the Closing Date. The Exchange
Offer shall be on the appropriate form permitting (i) registration of the
Exchange Notes to be offered in exchange for the Notes that are Transfer
Restricted Securities and (ii) resales of Exchange Notes by Broker-Dealers that
tendered the Exchange Notes that such Broker-Dealer acquired for its own account
as a result of market making activities or other trading activities (other than
Notes acquired directly from the Company or any of its Affiliates) as
contemplated by Section 3(c) below.

                                      -3-
<PAGE>   4

       (b) The Company shall use its best efforts to cause the Exchange Offer
Registration Statement to be effective continuously and shall keep the Exchange
Offer open for a period of not less than the minimum period required under
applicable federal and state securities laws to Consummate the Exchange Offer;
provided, however, that in no event shall such period be less than 20 business
days. The Company shall cause the Exchange Offer to comply with all applicable
federal and state securities laws. No securities other than the Exchange Notes
shall be included in the Exchange Offer Registration Statement. The Company
shall use its best efforts to cause the Exchange Offer to be Consummated not
later than the 295th day after the Closing Date (such 295th day being the
"CONSUMMATION DEADLINE").

       (c) The Company shall include a "Plan of Distribution" section in the
Prospectus contained in the Exchange Offer Registration Statement and indicate
therein that any Broker-Dealer who holds Transfer Restricted Securities that
were acquired for the account of such Broker-Dealer as a result of market-making
activities or other trading activities (other than Notes acquired directly from
the Company or any Affiliate of the Company), may exchange such Transfer
Restricted Securities pursuant to the Exchange Offer. Such "Plan of
Distribution" section shall also contain all other information with respect to
such sales by such Broker-Dealers that the Commission may require in order to
permit such sales pursuant thereto, but such "Plan of Distribution" shall not
name any such Broker-Dealer or disclose the amount of Transfer Restricted
Securities held by any such Broker-Dealer, except to the extent required by the
Commission as a result of a change in policy, rules or regulations after the
date of this Agreement.

       Because such Broker-Dealer may be deemed to be an "underwriter" within
the meaning of the Act and must, therefore, deliver a prospectus meeting the
requirements of the Act in connection with any initial sale of any Exchange
Notes received by such Broker-Dealer in the Exchange Offer, the Company shall
permit the use of the prospectus contained in the Exchange Offer Registration
Statement by such Broker-Dealer to satisfy such Prospectus delivery requirement.
To the extent necessary to ensure that the prospectus contained in the Exchange
Offer Registration Statement is available for sales of Exchange Notes by
Brokers-Dealers, the Company shall use its best efforts to keep the Exchange
Offer Registration Statement continuously effective, supplemented, amended and
current as required by and subject to the provisions of Sections 6(a) and 6(c)
hereof and in conformity with the requirements of this Agreement, the Act and
the policies, rules and regulations of the Commission as announced from time to
time, for a period of one year from the date on which the Exchange Offer is
Consummated or such shorter period as will terminate when all Transfer
Restricted Securities covered by such Registration Statement have been sold
pursuant thereto. The Company shall provide sufficient copies of the latest
version of such Prospectus to such Broker-Dealers, promptly upon request, and in
no event later than one day after such request, at any time during such period.

SECTION 4. SHELF REGISTRATION

       (a) Shelf Registration. If (i) the Exchange Offer is not permitted by
applicable law or Commission policy (after the Company has complied with the
procedures set forth in Section 6(a) below) or (ii) if any Holder of Transfer
Restricted Securities shall notify the Company within 20 business days following
the date on which the Exchange Offer is Consummated that (A) such Holder was
prohibited by applicable law or Commission policy from participating in the
Exchange Offer, or (B) such Holder may not resell the Exchange Notes acquired by
it in the Exchange Offer to the public without delivering a prospectus and that
the Prospectus contained in the Exchange Offer Registration Statement is not
appropriate or available for such resales by such Holder, or (C) that such
Holder is a Broker-Dealer and holds Notes acquired directly from the Company or
any of its Affiliates, then the Company shall:

              (x) cause to be filed a shelf registration statement pursuant to
Rule 415 under the Act (which may be an amendment to the Exchange Offer
Registration Statement) the ("SHELF REGISTRATION STATEMENT"), relating to all
Transfer Restricted Securities, on or prior to 30 days after the later of (1)
the date on which the Company determines that the Exchange Offer Registration
Statement cannot be filed as a result of clause (a)(i) above, (2) the date on
which the Company receives notice specified in clause (a)(ii) above, and (3) the
120th day after the Closing Date (such earlier date, the "FILING DEADLINE"); and

              (y) shall use its best efforts to cause such Shelf Registration
Statement to become effective on or prior to the 90th day after the Filing
Deadline (such 90th day the "EFFECTIVENESS DEADLINE").

To the extent necessary to ensure that the Shelf Registration Statement is
available for sales of Transfer Restricted Securities by the Holders thereof
entitled to the benefit of this Section 4(a) and other securities required to be
registered therein pursuant to Section 6(b)(ii) hereof, the Company shall use
its best efforts to keep such Shelf Registration Statement required by this
Section 4(a) continuously effective, supplemented, amended and current as
required by and subject to the provisions of Sections 6(b) and (c) hereof and in
conformity with the requirements of this Agreement, the Act and the policies,
rules and regulations of the Commission as announced from time to time, for a
period of at least two years (as extended pursuant to Section 6(d) hereof)
following the Closing Date or such shorter period as will terminate where all
Transfer Restricted Securities covered by such Shelf Registration Statement have
been sold pursuant thereto.

       (b) Provision by Holders of Certain Information in connection with the
Shelf Registration Statement. No Holder of Transfer Restricted Securities may
include any of its Transfer Restricted Securities in any Shelf Registration
Statement pursuant to this Agreement unless and until such Holder furnishes to
the Company in writing, within 20 days after receipt of a request therefor, the
information specified in Item 507 or 508 of Regulation S-K, as applicable, of
the Act for use in connection with any Shelf Registration Statement or
Prospectus or preliminary Prospectus included therein. No Holder of Transfer
Restricted Securities shall be entitled to liquidated damages pursuant to
Section 5 hereof unless and until such Holder shall have used its best efforts
to provide all such information. Each Selling Holder agrees to furnish promptly
to the Company all information required to be disclosed in order to make the
information previously furnished to the Company by such Holder not materially
misleading.

SECTION 5. LIQUIDATED DAMAGES

       If (i) any Registration Statement required by this Agreement is not filed
with the Commission on or prior to the applicable Filing Deadline, (ii) any such
Registration Statement has not been declared effective by the Commission on or
prior to the applicable Effectiveness Deadline, (iii) the Exchange Offer has not
been Consummated on or prior to the Consummation Deadline or (iv) any
Registration Statement required by this Agreement is filed and declared
effective but shall thereafter cease to be effective or fail to be usable for
its intended purpose without being succeeded immediately by a post-effective
amendment to such Registration Statement that cures such failure and that is
itself immediately declared effective (each such event referred to in clauses
(i) through (iv), a "REGISTRATION DEFAULT"), then the Company hereby agrees to
pay liquidated damages to each Holder of Transfer Restricted Securities for the
first 90-day period immediately following the occurrence of such Registration
Default, in an amount equal to $.05 per week per $1,000 in principal amount of
Transfer Restricted Securities held by such Holder for each week or portion
thereof that the Registration Default continues. The amount of the liquidated
damages shall increase by an additional $.05 per week per $1,000 in principal
amount of Transfer Restricted Securities with respect to each subsequent 90-day
period until all Registration Defaults have been cured or no Transfer Restricted
Securities are outstanding, up to a maximum amount of liquidated damages of $.30
per week per $1,000 in principal amount of Transfer Restricted Securities;
provided that the Company shall in no event be required to pay liquidated
damages for more than one Registration Default at any given time. All accrued
liquidated damages shall be paid to the Holders entitled thereto, in the manner
provided for the payment of interest, on each Interest Payment Date, as more
fully set forth in the Indenture and the Notes. Notwithstanding anything to the
contrary set forth herein, (1) upon filing of the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement), in the case
of (i) above, (2) upon the effectiveness of the Exchange Offer Registration
Statement (and/or, if applicable, the Shelf Registration Statement), in the case
of (ii) above, (3) upon Consummation of the Exchange Offer, in the case of (iii)
above, or (4) upon the filing of a post-effective amendment to the Registration
Statement or an additional Registration Statement that causes the Exchange Offer
Registration Statement (and/or, if applicable, the Shelf Registration Statement)
to again be declared effective or made usable in the case of (iv) above, the
liquidated damages payable with respect to the Transfer Restricted Securities as
a result of such clause (i), (ii), (iii) or (iv), as applicable, shall cease.

       Notwithstanding the fact that any securities for which liquidated damages
are due cease to be Transfer Restricted Securities, all obligations of the
Company to pay liquidated damages with respect to securities shall survive until
such time as such obligations with respect to such securities shall have been
satisfied in full.

SECTION 6. REGISTRATION PROCEDURES

       (a) Exchange Offer Registration Statement. In connection with the
Exchange Offer, the Company shall (x) comply with all of the provisions of
Section 6(c) below, (y) use its best efforts to effect such exchange and to
permit the resale of Exchange Notes by Broker-Dealers that tendered in the
Exchange Offer Notes that such Broker-Dealer acquired for its own account as a
result of its market making activities as other trading activities (other than
Notes acquired directly from the Company or any of its Affiliates) being sold in
accordance with the intended method or methods of distribution thereof, and (z)
comply with all of the following provisions:

              (i) If, following the date hereof there has been announced a
change in Commission policy with respect to exchange offers such as the Exchange
Offer, that in the reasonable opinion of counsel to the Company raises a
substantial question as to whether the Exchange Offer is permitted by applicable
federal law, the Company hereby agrees to seek a no-action letter or other
favorable decision from the Commission allowing the Company to Consummate an
Exchange Offer for such Transfer Restricted Securities. The Company agrees to
pursue the issuance of such a decision to the Commission staff level. In
connection with the foregoing, the Company agrees, to take all such other
actions as may be requested by the Commission or otherwise required in
connection with the issuance of such decision, including without limitation (A)
participating in telephonic conferences with the Commission, (B) delivering to
the Commission staff an analysis prepared by counsel to the Company setting
forth the legal bases, if any, upon which such counsel has concluded that such
an Exchange Offer should be permitted and (C) diligently pursuing a resolution
(which need not be favorable) by the Commission staff.

              (ii) As a condition to its participation in the Exchange Offer,
each Holder of Transfer Restricted Securities (including, without limitation,
any Holder who is a Broker-Dealer) shall furnish, upon the request of the
Company, prior to the Consummation of the Exchange Offer, a written
representation to the Company (which may be contained in the letter of
transmittal contemplated by the Exchange Offer Registration Statement) to the
effect that (A) it is not an Affiliate of the Company, (B) it is not engaged in,
and does not intend to engage in, and has no arrangement or understanding with
any person to participate in, a distribution of the Exchange Notes to be issued
in the Exchange Offer and (C) it is acquiring the Exchange Notes in its ordinary
course of business. Each Holder using the Exchange Offer to participate in a
distribution of the Exchange Notes shall acknowledge and agree that, if the
resales are of Exchange Notes obtained by such Holder in exchange for Notes
acquired by such Holder directly from the Company or an Affiliate thereof, it
(1) could not, under Commission policy as in effect on the date of this
Agreement rely on the position of the Commission enunciated in Morgan Stanley
and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation
(available May 13, 1988), as interpreted in the Commission's letter to Shearman
& Sterling dated July 2, 1993, and similar no-action letters (including, if
applicable, any no-action letter obtained pursuant to clause (i) above), and (2)
must comply with the registration and prospectus delivery requirements of the
Act in connection with a secondary resale transaction and that such a secondary
resale transaction should be covered by an effective registration statement
containing the

                                      -7-
<PAGE>   8

selling security holder information required by Item 507 or 508, as applicable,
of Regulation S-K.

              (iii) Prior to effectiveness of the Exchange Offer Registration
Statement, the Company shall provide a supplemental letter to the Commission (A)
stating that the Company is registering the Exchange Offer in reliance on the
position of the Commission enunciated in Exxon Capital Holdings Corporation
(available May 13, 1988), Morgan Stanley and Co., Inc. (available June 5, 1991)
as interpreted in the Commission's letter to Shearman & Sterling, dated July 2,
1993, and, if applicable, any no-action letter obtained pursuant to clause (i)
above, (B) including a representation that neither the Company nor any Guarantor
has entered into any arrangement or understanding with any Person to distribute
the Exchange Notes to be received in the Exchange Offer and that, to the best of
the Company's information and belief, each Holder participating in the Exchange
Offer is acquiring the Exchange Notes in its ordinary course of business and has
no arrangement or understanding with any Person to participate in the
distribution of the Exchange Notes received in the Exchange Offer and (C) any
other undertaking or representation required by the Commission as set forth in
any no-action letter obtained pursuant to clause (i) above, if applicable.

       (b) Shelf Registration Statement. In connection with the Shelf
Registration Statement, the Company shall: (i) comply with all the provisions of
Section 6(c) below and shall use its best efforts to effect such registration to
permit the sale of the Transfer Restricted Securities being sold in accordance
with the intended method or methods of distribution thereof (as indicated in the
information furnished to the Company pursuant to Section 4(b) hereof), and
pursuant thereto the Company will prepare and file with the Commission a
Registration Statement relating to the registration on any appropriate form
under the Act, which form shall be available for the sale of the Transfer
Restricted Securities in accordance with the intended method or methods of
distribution thereof within the time periods and otherwise in accordance with
the provisions hereof and (ii) issue, upon the request of any Holder or
purchaser of Notes covered by any Shelf Registration Statement contemplated by
this Agreement, Exchange Notes having an aggregate principal amount equal to the
aggregate principal amount of Notes sold pursuant to the Shelf Registration
Statement and surrendered to the Company for cancellation; the Company shall
register Exchange Notes on the Shelf Registration Statement for this purpose and
issue the Exchange Notes to the purchasers of securities subject to the Shelf
Registration Statement in the names as such purchasers shall designate.

       (c) General Provisions. In connection with any Registration Statement and
any related Prospectus required by this Agreement, the Company shall:

              (i) use its best efforts to keep such Registration Statement
continuously effective and provide all requisite financial statements for the
period specified in Section 3 or 4 of this Agreement, as applicable. Upon the
occurrence of any event that would cause any such Registration Statement or the
Prospectus contained therein (A) to contain an untrue statement of material fact
or omit to state any material fact necessary to make the statements therein not
misleading or (B) not to be effective and usable for resale of Transfer
Restricted Securities during the period required by this Agreement, the Company
shall file promptly an appropriate amendment to such Registration Statement,

                                      -8-
<PAGE>   9

curing such defect, and if Commission review is required, use its best efforts
to cause such amendment to be declared effective as soon as practicable;

              (ii) prepare and file with the Commission such amendments and
post-effective amendments to the Registration Statement as may be necessary to
keep such Registration Statement effective for the applicable period set forth
in Section 3 or 4 hereof, as the case may be; cause the Prospectus to be
supplemented by any required Prospectus supplement, and as so supplemented to be
filed pursuant to Rule 424 under the Act, and to comply fully with the
applicable provisions of Rules 424 and 430A under the Act in a timely manner;
and comply with the provisions of the Act with respect to the disposition of all
securities covered by such Registration Statement during the applicable period
in accordance with the intended method or methods of distribution by the sellers
thereof set forth in such Registration Statement or supplement to the
Prospectus;

              (iii) advise the underwriters, if any, and each selling Holder
promptly and, if requested by such Holder, confirm such advice in writing, (A)
when the Prospectus or any Prospectus supplement or post-effective amendment has
been filed, and, with respect to any Registration Statement or any
post-effective amendment thereto, when the same has become effective, (B) of any
request by the Commission for amendments to the Registration Statement or
amendments or supplements to the Prospectus or for additional information
relating thereto, (C) of the issuance by the Commission of any stop order
suspending the effectiveness of the Registration Statement under the Act or of
the suspension by any state securities commission of the qualification of the
Transfer Restricted Securities for offering or sale in any jurisdiction, or the
initiation of any proceeding for any of the preceding purposes, and (D) of the
existence of any fact or the happening of any event that makes any statement of
a material fact made in the Registration Statement, the Prospectus, any
amendment or supplement thereto, or any document incorporated by reference
therein untrue, or that requires the making of any additions to or changes in
the Registration Statement or the Prospectus in order to make the statements
therein not misleading, or that requires the making of any additions to or
changes in the Prospectus in order to make the statements therein in the light
of the circumstances under which they were made, not misleading. If at any time
the Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, or any state securities commission or other regulatory
authority shall issue an order suspending the qualification or exemption from
qualification of the Transfer Restricted Securities under state securities or
Blue Sky laws, the Company shall use its best efforts to obtain the withdrawal
or lifting of such order at the earliest possible time;

              (iv) furnish to each selling Holder and each of the underwriters,
if any, in connection with such exchange or sale, if any, before filing with the
Commission, copies of any Registration Statement or any Prospectus included
therein or any amendments or supplements to any such Registration Statement or
Prospectus (including all documents incorporated by reference after the initial
filing of such Registration Statement), which documents will be subject to the
review and comment of such Holders and underwriter(s), if any, in connection
with such sale, if any, for a period of at least five business days, and the
Company will not file any such Registration Statement or Prospectus or any
amendment or supplement to any such Registration Statement or Prospectus
(including all such documents incorporated by reference) to which such Holders
or the underwriters, if any, shall reasonably object within five business days

                                      -9-
<PAGE>   10

after the receipt thereof. A Holder or underwriter, if any, shall be deemed to
have reasonably objected to such filing if such Registration Statement,
amendment, Prospectus or supplement, as applicable, as proposed to be filed,
contains an untrue statement of a material fact or omits to state any material
fact necessary to make the statements therein not misleading or fails to comply
with the applicable requirements of the Act;

              (v) promptly prior to the filing of any document that is to be
incorporated by reference into a Registration Statement or Prospectus, provide
copies of such document to each selling Holder and to the underwriters, if any,
in connection with such exchange or sale, if any, make the Company's
representatives available for discussion of such document and other customary
due diligence matters, and include such information in such document prior to
the filing thereof as such Holders or underwriters, if any, reasonably may
request;

              (vi) make available, at reasonable times, for inspection by each
selling Holder, any underwriter, if any, participating in any disposition
pursuant to such Registration Statement, and any attorney or accountant retained
by such Holders or any of the underwriters, all financial and other records,
pertinent corporate documents and properties of the Company and cause the
Company's officers, directors and employees to supply all information reasonably
requested by any such Holder, underwriter, attorney or accountant in connection
with such Registration Statement or any post-effective amendment thereto
subsequent to the filing thereof and prior to its effectiveness;

              (vii) if requested by any Holders or the underwriters, if any, in
connection with such exchange or sale, promptly include in any Registration
Statement or Prospectus, pursuant to a supplement or post-effective amendment if
necessary, such information as such Holders and underwriters, if any, may
reasonably request to have included therein, including, without limitation,
information relating to the "Plan of Distribution" of the Transfer Restricted
Securities; and make all required filings of such Prospectus supplement or
post-effective amendment as soon as practicable after the Company is notified of
the matters to be included in such Prospectus supplement or post-effective
amendment;

              (viii) cause the Transfer Restricted Securities covered by the
Registration Statement to be rated with the appropriate rating agencies, if so
requested by the Holders of a majority in aggregate principal amount of Notes
covered thereby or the underwriters, if any;

              (ix) furnish to each selling Holder (and upon request, any Holder)
and each of the underwriter(s), if any, in connection with such exchange or
sale, without charge, at least one copy of the Registration Statement, as first
filed with the Commission, and of each amendment thereto, including all
documents incorporated by reference therein and all exhibits (including exhibits
incorporated therein by reference);

              (x) deliver to each Holder and each of the underwriters, if any,
without charge, as many copies of the Prospectus (including each preliminary
prospectus) and any amendment or supplement thereto as such Persons reasonably
may request; the Company hereby consents to the use (in accordance with
applicable law) of the

                                      -10-
<PAGE>   11

Prospectus and any amendment or supplement thereto by each selling Holder and
each underwriter, if any, in connection with the offering and the sale of the
Transfer Restricted Securities covered by the Prospectus or any amendment or
supplement thereto;

              (xi) upon the request of any selling Holder, enter into such
agreements (including underwriting agreements), and make, such representations
and warranties, and take all such other actions in connection therewith in order
to expedite or facilitate the disposition of the Transfer Restricted Securities
pursuant to any Registration Statement contemplated by this Agreement, as may be
requested by any Initial Purchaser or by any selling Holder in connection with
any sale or resale pursuant to any Registration Statement. In such connection,
the Company shall:

              (A) upon request of any Holder, furnish to each Initial Purchaser,
       each selling Holder and each underwriter, if any, in such substance and
       scope as they may request and as are customarily made by issuers to
       underwriters in primary underwritten offerings, upon the Consummation of
       the Exchange Offer or upon, the effectiveness of the Shelf Registration
       Statement, as the case may be:

                     (1) a certificate, dated such date signed on behalf of the
              Company by (x) the President or any Vice President and (y) a
              principal financial or accounting officer of the Company,
              confirming, as of the date thereof, the matters set forth in
              Sections 6(hh), 9(a) and 9(b) of the Purchase Agreement and such
              other matters as such parties may reasonably request;

                     (2) an opinion, dated the date of Consummation of the
              Exchange Offer or the date of effectiveness of the Shelf
              Registration Statement, as the case may be, of counsel for the
              Company, covering the matters similar to those set forth in
              paragraphs (e), (f) and (g) of Section 9 of the Purchase Agreement
              and such other matters as such parties may reasonably request, and
              in any event including a statement to the effect that such counsel
              has participated in conferences with officers and other
              representatives of the Company, representatives of the independent
              public accountants for the Company, the Initial Purchasers'
              representatives and the Initial Purchasers' counsel in connection
              with the preparation of such Registration Statement and the
              related Prospectus and have considered the matters required to be
              stated therein and the statements contained therein, although such
              counsel has not independently verified the accuracy, completeness
              or fairness of such statements; and that such counsel advises
              that, on the basis of the foregoing (relying as to materiality to
              the extent such counsel deems appropriate upon the statements of
              officers and other representatives of the Company and without
              independent check or verification), no facts came to such
              counsel's attention that caused such counsel to believe that the
              applicable Registration Statement, at the time such Registration
              Statement or any post-effective amendment thereto became
              effective, and, in the case of the Exchange Offer Registration
              Statement, as of the date of Consummation of the Exchange Offer,
              contained an untrue statement of a material fact or omitted to
              state a material fact required to be stated therein or necessary
              to make the statements therein not misleading, or that the
              Prospectus contained in such Registration Statement as of its date
              and, in the case of the

                                      -11-
<PAGE>   12

              opinion dated the date of Consummation of the Exchange Offer, as
              of the date of Consummation, contained an untrue statement of a
              material fact or omitted to state a material fact necessary in
              order to make the statements therein, in the light of the
              circumstances under which they were made, not misleading. Without
              limiting the foregoing, such counsel may state further that such
              counsel assumes no responsibility for, and has not independently
              verified, the accuracy, completeness or fairness of the financial
              statements, notes and schedules and other financial data included
              in any Registration Statement contemplated by this Agreement or
              the related Prospectus; and

                     (3) a customary comfort letter, dated as of the date of
              Consummation of the Exchange Offer, or as of the date of
              effectiveness of the Shelf Registration Statement, as the case may
              be, from the Company's independent accountants, in the customary
              form and covering matters of the type customarily covered in
              comfort letters to underwriters in connection with primary
              underwritten offerings, and affirming the matters set forth in the
              comfort letters delivered pursuant to Section 9(i) of the Purchase
              Agreement, without exception; and

              (B) deliver such other documents and certificates as may be
       reasonably requested by such parties to evidence compliance with the
       matters covered in clause (A) above and with any customary conditions
       contained in any agreement or other agreement entered into by the Company
       pursuant to this clause (xi), if any.

       If at any time the representations and warranties of the Company
contemplated in clause (A)(1) above cease to be true and correct, the Company
shall so advise the Initial Purchasers and the underwriter(s), if any, and each
selling Holder promptly and, if requested by such Persons, shall confirm such
advice in writing;

              (xii) prior to any public offering of Transfer Restricted

their respective counsel in connection with the registration and qualification
of the Transfer Restricted Securities under the securities or Blue Sky laws of
such jurisdictions as the selling Holders or underwriters may request and do any
and all other acts or things necessary or advisable to enable the disposition in
such jurisdictions of the Transfer Restricted Securities covered by the
applicable Registration Statement; provided, however, that the Company shall not
be required to register or qualify as a foreign corporation where it is not now
so qualified or to take any action that would subject it to the service of
process in suits or to taxation, other than as to matters and transactions
relating to the Registration Statement, in any jurisdiction where it is not now
so subject;

              (xiii) shall issue, upon the request of any Holder of Notes
covered by the Shelf Registration Statement, Exchange Notes, having an aggregate
principal amount equal to the aggregate principal amount of Notes surrendered to
the Company by such Holder in exchange therefor or being sold by such Holder;
such Exchange Notes to be registered in the name of such Holder or in the name
of the purchaser(s) of such Notes or Exchange Notes, as the case may be; in
return, the Notes held by such Holder shall be surrendered to the Company for
cancellation;

                                      -12-
<PAGE>   13

              (xiv) in connection with any sale of Transfer Restricted
Securities that will result in such securities no longer being Transfer
Restricted Securities, cooperate with the Holders and the underwriters, if any,
to facilitate the timely preparation and delivery of certificates representing
Transfer Restricted Securities to be sold and not bearing any restrictive
legends; and to register such Transfer Restricted Securities in such
denominations and in such names as the selling Holders or the underwriters, if
any, may request at least two business days prior to any such sale of Transfer
Restricted Securities;

              (xv) use its best efforts to cause the disposition of the Transfer
Restricted Securities covered by the Registration Statement to be registered
with or approved by such other governmental agencies or authorities as may be
necessary to enable the seller or sellers thereof or the underwriters, if any,
to consummate the disposition of such Transfer Restricted Securities, subject to
the proviso contained in clause (xii) above;

              (xvi) subject to Section 6(c)(i), if any fact or event
contemplated by Section 6(c)(iii)(D) above shall exist or have occurred, prepare
a supplement or post-effective amendment to the Registration Statement or
related Prospectus or any document incorporated therein by reference or file any
other required document so that, as thereafter delivered to the purchasers of
Transfer Restricted Securities, the Prospectus will not contain an untrue
statement of a material fact or omit to state any material fact necessary to
make the statements therein, not misleading;

              (xvii) provide a CUSIP number for all Transfer Restricted
Securities not later than the effective date of a Registration Statement
covering such Transfer Restricted Securities and provide the Trustee under the
Indenture with printed certificates for the Transfer Restricted Securities which
are in a form eligible for deposit with the Depositary Trust Company;

              (xviii) cooperate and assist in any filings required to be made
with the NASD and in the performance of any due diligence investigation by any
underwriter (including any "qualified independent underwriter") that is required
to be retained in accordance with the rules and regulations of the NASD, and use
its reasonable best efforts to cause such Registration Statement to become
effective and approved by such governmental agencies or authorities as may be
necessary to enable the Holders selling Transfer Restricted Securities to
consummate the disposition of such Transfer Restricted Securities;

              (xix) otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission, and make generally available to its
security holders with regard to any Registration Statement, as soon as
practicable, a consolidated earnings statement meeting the requirements of Rule
158 (which need not be audited) covering a twelve-month period, beginning after
the effective date of the Registration Statement (as such term is defined in
paragraph (c) of rule 158 under the Act);

              (xx) cause the Indenture to be qualified under the TIA not later
than the effective date of the first Registration Statement required by this
Agreement, and, in connection therewith, cooperate with the Trustee and the
Holders to effect such changes to the Indenture as may be required for such
Indenture to be so qualified in accordance with the terms of the TIA; and
execute, and use its best efforts to cause the Trustee to

                                      -13-
<PAGE>   14

execute, all documents that may be required to effect such changes and all other
forms and documents required to be filed with the Commission to enable such
Indenture to be so qualified in a timely manner;

              (xxi) cause all Transfer Restricted Securities covered by the
Registration Statement to be listed on each securities exchange on which similar
securities issued by the Company are then listed if requested by the Holders of
a majority in aggregate principal amount of Notes or the managing underwriters,
if any; and

              (xxii) provide promptly to each Holder, upon request, each
document filed with the Commission pursuant to the requirements of Section 13 or
Section 15(d) of the Exchange Act.

       (d) Restrictions on Holders. Each Holder agrees by acquisition of a
Transfer Restricted Security that, upon receipt of the notice referenced to in
Section 6(c)(iii)(D) or any notice from the Company of the existence of any fact
of the kind described in Section 6(c)(iii)(D) hereof (in each case, a
"SUSPENSION NOTICE"), such Holder will forthwith discontinue disposition of
Transfer Restricted Securities pursuant to the applicable Registration Statement
until (i) such Holder has received copies of the supplemented or amended
Prospectus contemplated by Section 6(c)(xvi) hereof, or (ii) such Holder is
advised in writing by the Company that the use of the Prospectus may be resumed,
and has received copies of any additional or supplemental filings that are
incorporated by reference in the Prospectus (in each case, the "RECOMMENCEMENT
DATE"). Each Holder receiving a Suspension Notice hereby agrees that it will
either (i) destroy any Prospectuses, other than permanent file copies then in
such Holder's possession which have been replaced by the Company with more
recently dated Prospectuses, or (ii) will deliver to the Company (at the
Company's expense) all copies, other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Transfer Restricted
Securities that was current at the time of receipt of such Suspension Notice.
The time period regarding the effectiveness of such Registration Statement set
forth in Section 3 or 4 hereof, as applicable, shall be extended by a number of
days equal to the number of days in the period from and including the date of
delivery of the Suspension Notice to the date of the Recommencement Date.

SECTION 7. REGISTRATION EXPENSES

       (a) All expenses incident to the Company's performance of or compliance
with this Agreement will be borne by the Company, regardless of whether a
Registration Statement becomes effective, including without limitation: (i) all
registration and filing fees and expenses (including filings made by any Initial
Purchaser or Holder with the NASD (and, if applicable, the fees and expenses of
any "qualified independent underwriter" and its counsel that may be required by
the rules and regulations of the NASD)); (ii) all fees and expenses of
compliance with federal securities and state Blue Sky or securities laws; (iii)
all expenses of printing (including printing certificates for the Exchange Notes
to be issued in the Exchange Offer and printing of Prospectuses), messenger and
delivery services and telephone; (iv) all fees and disbursements of counsel for
the Company and, subject to Section 7(b), the Holders of Transfer Restricted
Securities; (v) all application and filing fees in connection with listing
Exchange Notes on

                                      -14-
<PAGE>   15

a national securities exchange automated quotation system pursuant to the
requirements hereof; and (vi) all fees and disbursements of independent
certified public accountants of the Company (including the expenses of any
special audit and comfort letters required by or incidental to such
performance).

       The Company will, in any event, bear its internal expenses (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expenses of any annual audit and the
fees and expenses of any Person, including special experts, retained by the
Company.

       (b) In connection with any Registration Statement required by this
Agreement (including, without limitation, the Exchange Offer Registration
Statement and the Shelf Registration Statement), the Company will reimburse the
Initial Purchasers and the Holders of Transfer Restricted Securities who are
tendering Notes in the Exchange Offer and/or selling or reselling Notes or
Exchange Notes pursuant to the "Plan of Distribution" contained in the Exchange
Offer Registration Statement or the Shelf Registration Statement, as applicable,
for the reasonable fees and disbursements of not more than one counsel, who
shall be Paul, Hastings, Janofsky & Walker LLP, unless another firm shall be
chosen by the Holders of a majority in principal amount of the Transfer
Restricted Securities for whose benefit such Registration Statement is being
prepared.

SECTION 8. INDEMNIFICATION

       (a) The Company agrees to indemnify and hold harmless (i) each Holder and
(ii) each Person, if any, who controls such Holder (within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act) any Holder (any of the
persons referred to in this clause (ii) being hereinafter referred to as a
"controlling person") and (iii) the respective officers, directors, partners,
employees, representatives and agents of any Holder or any controlling person,
from and against any and all losses, claims, damages, liabilities, judgments,
actions and expenses (including, without limitation, any legal or other expenses
incurred in connection with, investigating, preparing, pursuing or defending any
claim or action, or any investigation or proceeding by any governmental agency
or body, commenced or threatened, including any action that could give rise to
any such losses, claims, damages, liabilities or judgments) directly or
indirectly caused by, related to, based upon, arising out of or in connection
with any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement, preliminary prospectus or Prospectus
(or any amendment or supplement thereto), provided by the Company to any Holder
or any prospective purchaser of Exchange Notes or registered Notes or caused by
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
except insofar as such losses, claims, damages, liabilities, judgments, actions
or expenses are caused by an untrue statement or omission or alleged untrue
statement or omission that is based upon information relating to such Holder
furnished in writing to the Company by such Holder.

       (b) Each Holder of Transfer Restricted Securities agrees, severally and
not jointly, to indemnify and hold harmless the Company, and its directors and
officers, and each

                                      -15-
<PAGE>   16

person, if any, who controls (within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act) the Company, to the same extent as the foregoing
indemnity from the Company set forth in Section 8(a) above, but only with
reference to information relating to such Holder furnished in writing to the
Company by such Holder expressly for use in any Registration Statement. In no
event shall any Holder, its directors, officers, or any person who controls such
Holder be liable or responsible for any amount in excess of the amount by which
the entire amount received by such Holder with respect to its sale of the
Transfer Restricted Securities pursuant to a Registration Statement exceeds (i)
the amount paid by such Holder for such Transfer Restricted Securities and (ii)
the amount of any damages that such Holder, its directors, officers or any
Person who controls such Holder has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission.

       (c) In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), a Holder shall not be required to assume the
defense of such action pursuant to this Section 8(c), but may employ separate
counsel and participate in the defense thereof, but the fees and expenses of
such counsel, except as provided below, shall be at the expense of the Holder).
Any indemnified party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of the indemnified party unless (i) the
employment of such counsel shall have been specifically authorized in writing by
the indemnifying party, (ii) the indemnifying party shall have failed to assume
the defense of such action or employ counsel reasonably satisfactory to the
indemnified party or (iii) the named parties to any such action (including any
impleaded parties) include both the indemnified party and the indemnifying
party, and the indemnified party shall have been advised by such counsel that
there may be one or more legal defenses available to it which are different from
or additional to those available to the indemnifying party (in which case the
indemnifying party shall not have the right to assume the defense of such action
on behalf of the indemnified party). In any such case, the indemnifying party
shall not, in connection with any one action or separate but substantially
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (in addition to any local counsel) for
all indemnified parties and all such fees and expenses shall be reimbursed as
they are incurred. Such firm shall be designated in writing by a majority of the
Holders, in the case of the parties indemnified pursuant to Section 8(a), and by
the Company, in the case of parties indemnified pursuant to Section 8(b). The
indemnifying party shall indemnify and hold harmless the indemnified party from
and against any and all losses, claims, damages, liabilities, judgments and
expenses by reason of any settlement of any action (i) effected with its written
consent or (ii) effected without its written consent if the settlement is
entered into more than twenty business days after the indemnifying party shall
have received a request from the indemnified party for reimbursement for the
fees and expenses of counsel (in any case where such fees and expenses are at
the expense of the indemnifying party) and,

                                      -16-
<PAGE>   17

prior to the date of such settlement, the indemnifying party shall have failed
to comply with such reimbursement request. No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement or
compromise of, or consent to the entry of judgment with respect to, any pending
or threatened action in respect of which the indemnified party is or could have
been a party and indemnity or contribution may be or could have been sought
hereunder by the indemnified party, unless such settlement, compromise or
judgment (i) includes an unconditional release of the indemnified party from all
liability on claims that are or could have been the subject matter of such
action and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act, by or on behalf of the indemnified party.

       (d) To the extent that the indemnification provided for in this Section 8
is unavailable to an indemnified party under Section 8(a) or Section 8(b) hereof
in respect of any losses, claims, damages, liabilities, judgements or expenses
referred to therein, then each indemnifying party, in lieu of indemnifying such
indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities,
judgments or expenses (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company, on the one hand, and the Holders, on
the other hand, from their sale of Transfer Restricted Securities or (ii) if the
allocation provided by clause 8(d)(i) is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause 8(d)(i) above but also the relative fault of the Company,
on the one hand, and of the Holder, on the other hand, in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities, judgments or expenses, as well as any other relevant equitable
considerations. The relative fault of the Company, on the one hand, and of the
Holder, on the other hand, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company, on the one hand, or by such Holder, on the other hand,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

       The Company, and each Holder agree that it would not be just and
equitable if contribution pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities, judgments or expenses referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
indemnified party in connection with investigating or defending any such action
or claim including any action that could have given rise to such losses, claims,
damages, liabilities, judgments or expenses. Notwithstanding the provisions of
this Section 8, no Holder shall be required to contribute, in the aggregate, any
amount in excess of the amount by which the total received by such Holder with
respect to the sale of Transfer Restricted Securities pursuant to a Registration
Statement exceeds (i) the amount paid by such Holder for such Transfer
Restricted Securities and (ii) the amount of any damages which such Holder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within

                                      -17-
<PAGE>   18

the meaning of Section 11(f) of the Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. The Holders'
obligations to contribute pursuant to this Section 8(d) are several in
proportion to the respective principal amount of Transfer Restricted Securities
held by each Holder hereunder and not joint.

SECTION 9. RULE 144A

       The Company hereby agrees with each Holder, for so long as any Transfer
Restricted Securities remain outstanding and during any period in which the
Company (i) is not subject to Section 13 or 15(d) of the Exchange Act, to make
available, upon request of any Holder, to such Holder or beneficial owner of
Transfer Restricted Securities in connection with any sale thereof and any
prospective purchaser of such Transfer Restricted Securities designated by such
Holder or beneficial owner, the information required by Rule 144A(d)(4) under
the Act in order to permit resales of such Transfer Restricted Securities
pursuant to Rule 144A, and (ii) is subject to Section 13 or 15(d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Transfer Restricted Securities pursuant to Rule 144.

SECTION 10. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS

       No Holder may participate in any Underwritten Registration hereunder
unless such Holder (a) agrees to sell such Holder's Transfer Restricted
Securities on the basis provided in any underwriting arrangements approved by
the Persons entitled hereunder to approve such arrangements and (b) completes
and executes all reasonable questionnaires, powers of attorney, indemnities,
underwriting agreements, lock-up letters and other documents required under the
terms of such underwriting arrangements.

SECTION 11. SELECTION OF UNDERWRITERS

       The Holders of Transfer Restricted Securities covered by the Shelf
Registration Statement who desire to do so may sell such Transfer Restricted
Securities in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Holders of a majority in
aggregate principal amount of the Transfer Restricted Securities included in
such offering; provided, that such investment bankers and managers must be
reasonably satisfactory to the Company.

SECTION 12. MISCELLANEOUS

       (a) Remedies. The Company acknowledges and agrees that any failure by the
Company to comply with its obligations under Sections 3 and 4 hereof may result
in material irreparable injury to the Initial Purchasers or Holders for which
there is no adequate remedy at law, that it will not be possible to measure
damages for such injuries precisely and that, in the event of any such failure,
the Initial Purchasers or any Holder

                                      -18-
<PAGE>   19

may obtain such relief as may be required to specifically enforce the Company's
obligations under Sections 3 and 4 hereof. The Company further agrees to waive
the defense in any action for specific performance that a remedy at law would be
adequate.

       (b) No Inconsistent Agreements. The Company will not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. The Company has not previously
entered into any agreement granting any registration rights with respect to its
securities to any Person. The rights granted to the Holders hereunder do not in
any way conflict with and are not inconsistent with the rights granted to the
holders of the Company's securities under any agreement in effect on the date
hereof.

       (c) Adjustments Affecting the Notes or Exchange Notes. The Company will
not take any action, or permit any change to occur, with respect to the Notes or
the Exchange Notes that would materially and adversely affect the ability of the
Holders to Consummate any Exchange Offer.

       (d) Amendments and Waivers. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from
the provisions hereof may not be given unless (i) in the case of Section 5
hereof and this Section 12(d)(i), the Company has obtained the written consent
of Holders of all outstanding Transfer Restricted Securities and (ii) in the
case of all other provisions hereof, the Company has obtained the written
consent of Holders of a majority of the outstanding principal amount of Transfer
Restricted Securities (excluding Transfer Restricted Securities held by the
Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent
to departure from the provisions hereof that relates exclusively to the rights
of Holders whose Transfer Restricted Securities are being tendered pursuant to
the Exchange Offer and that does not affect directly or indirectly the rights of
other Holders whose Transfer Restricted Securities are not being tendered
pursuant to such Exchange Offer may be given by the Holders of a majority of the
outstanding principal amount of Transfer Restricted Securities subject to such
Exchange Offer.

       (e) Third Party Beneficiary. The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to
enforce such agreements directly to the extent they may deem such enforcement
necessary or advisable to protect its rights or the rights of Holders hereunder.

       (f) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail

courier guaranteeing overnight delivery:
