                            1998, UNLESS EXTENDED.
 
  TCI Satellite Entertainment, Inc., a Delaware corporation ("TSAT"), hereby
offers (the "Exchange Offer"), upon the terms and subject to the conditions
set forth in this Prospectus and the accompanying Letter of Transmittal (the
"Letter of Transmittal"), (i) to exchange up to an aggregate principal amount
of $200,000,000 of its 10 7/8% Senior Subordinated Notes due February 15, 2007
(the "Senior Subordinated Exchange Notes") for an equal principal amount of
its outstanding 10 7/8% Senior Subordinated Notes due February 15, 2007 (the
"Senior Subordinated Notes"), in integral multiples of $1,000, and (ii) to
exchange up to an aggregate principal amount at maturity of $275,000,000 of
its 12 1/4% Senior Subordinated Discount Notes due February 15, 2007 (the
"Senior Subordinated Discount Exchange Notes," and, together with the Senior
Subordinated Exchange Notes, the "Exchange Notes") for an equal principal
amount at maturity of its outstanding 12 1/4% Senior Subordinated Discount
Notes due February 15, 2007 (the "Senior Subordinated Discount Notes," and,
together with the Senior Subordinated Notes, the "Notes"), in integral
multiples of $1,000. The Exchange Notes will be unsecured obligations of TSAT
and will rank junior to, and be subordinated in right of payment to, all
existing and future Senior Indebtedness (as defined) of TSAT. As of December
31, 1997, TSAT had approximately $79,949,000 of Senior Indebtedness
outstanding. The forms and terms of the Exchange Notes (including principal
amount, interest rate, maturity and redemption rights) are substantially
identical to those of the Notes for which they may be exchanged pursuant to
the Exchange Offer, except that (i) the offering and sale of the Exchange
Notes has been registered under the Securities Act of 1933, as amended (the
"Securities Act") and, therefore, the Exchange Notes shall not bear certain
legends restricting the transfer thereof, and (ii) holders of the Exchange
Notes will not be entitled to certain rights of holders of the Notes under
Registration Rights Agreements of TSAT dated as of February 20, 1997 (the
"Registration Rights Agreements"). The Notes have been issued under Indentures
dated as of February 20, 1997 (each, an "Indenture," and, together, the
"Indentures"), between TSAT and The Bank of New York, as trustee (the
"Trustee"), which Indentures have been qualified under the Trust Indenture Act
of 1939 ("TIA"). Each tranche of the Exchange Notes will be issued as a
separate series of notes pursuant to the same Indenture governing the
corresponding tranche of Notes for which such tranche of Exchange Notes will
be exchanged. Holders of the Exchange Notes shall be entitled to substantially
identical benefits under the Indentures as are holders of the Notes (other
than such changes as are necessary to comply with any requirements of the
Securities and Exchange Commission ("SEC") to effect or maintain the
qualification of each Indenture under the TIA). See "Description of the
Exchange Notes." TSAT will receive no proceeds from the Exchange Offer;
however, pursuant to the Registration Rights Agreements, TSAT will bear
certain expenses of the Exchange Offer.

  The Restructuring Transaction. The Notes are currently obligations of TSAT,
and the Exchange Notes, when issued, will initially be obligations of TSAT.
However, on February 6, 1998, TSAT and certain other parties entered into
definitive agreements with respect to a proposed business combination,
pursuant to which, among other things, (i) TSAT shall transfer and contribute
substantially all of its assets and liabilities to PRIMESTAR, Inc. ("New
PRIMESTAR"), a newly formed corporation and wholly owned subsidiary of TSAT,
and (ii) TSAT's existing partners in PRIMESTAR Partners, L.P. (the
"Partnership") shall concurrently transfer and contribute to New PRIMESTAR
their respective interests in the PRIMESTAR(R) digital satellite business
(collectively, the "Restructuring Transaction"). Accordingly, in connection
with the Restructuring Transaction, the obligations of TSAT under all Notes
and/or Exchange Notes outstanding at the consummation of the Restructuring
Transaction shall be assumed by New PRIMESTAR, which assumption shall be
evidenced by New PRIMESTAR's execution of supplemental indentures governing
such notes. As used herein, the term "Borrower" means (i) TSAT, at any time
prior to the consummation of the Restructuring Transaction and the effective
assumption by New PRIMESTAR of all obligations of TSAT under the Notes and the
Indentures (the "Assumption") and (ii) New PRIMESTAR, from and after the
consummation of the Restructuring Transaction and the effectiveness of the
Assumption.
 
  The Indentures provide that TSAT shall not consolidate with or merge with or
into any other entity, and TSAT shall not sell, transfer or otherwise dispose
of all or substantially all of its properties and assets to any entity in a
single transaction or series of related transactions, unless certain
conditions set forth in the Indentures are satisfied, including the
requirement that the surviving entity in any such merger or the transferee
with respect to any such asset transfer (in either case, the "Surviving
Person") must expressly assume, by execution of supplemental indentures, the
obligations to make due and punctual payment of the principal of, premium, if
any, and interest on all the Notes (and/or the Exchange Notes, as applicable)
and to perform and observe every covenant of the Indentures and the
Registration Rights Agreements to be performed or observed on the part of
TSAT. Furthermore, the Indentures provide that upon the satisfaction of such
conditions, the Surviving Person shall succeed to, and be substituted for, and
may exercise every right and power of, TSAT and TSAT shall be discharged from
its obligations under the Indentures and the Notes. The terms of the proposed
Restructuring Transaction satisfy the conditions set forth in the Indentures,
and accordingly, upon consummation of the Restructuring Transaction and the
execution and delivery by New PRIMESTAR of supplemental indentures expressly
assuming all of TSAT's obligations under the Indentures, New PRIMESTAR shall
succeed to, and be substituted for, and may exercise every right and power of,
TSAT and TSAT shall be discharged from its obligations under the Indentures
and the Notes.
 
  As a result of the Restructuring Transaction, New PRIMESTAR will own the
entire PRIMESTAR(R) digital satellite business and TSAT and its former
partners in that business (or their respective affiliates) will, in the
aggregate, own all the outstanding capital stock of New PRIMESTAR. The
Restructuring Transaction comprises the first step in TSAT's proposed two-step
plan (the "Roll-up Plan"). The Roll-up Plan provides that, subsequent to the
consummation of the Restructuring Transaction, TSAT shall merge with and into
New PRIMESTAR, with New PRIMESTAR as the surviving entity (the "TSAT Merger"),
pursuant to an Agreement and Plan of Merger (the "TSAT Merger Agreement")
dated as of February 6, 1998 between TSAT and New PRIMESTAR. Consummation of
the Restructuring Transaction and the TSAT Merger are subject to approval of
the stockholders of TSAT. TSAT has called a special meeting of its
stockholders, to be held on March 6, 1998, to consider and vote upon the
Restructuring Transaction and the TSAT Merger. In addition, the TSAT Merger is
subject to regulatory approval and other closing conditions set forth in the
TSAT Merger Agreement; accordingly, although, the Roll-up Plan envisions that
the TSAT Merger will be consummated after the Restructuring Transaction, there
can be no assurance that the TSAT Merger will be consummated, even if the
Restructuring Transaction is consummated.
 
  This Prospectus includes or otherwise incorporates by reference certain
financial and other information, including historical and pro forma financial
information, relating to the proposed Roll-up Plan. Holders of the Notes are
urged to carefully review such historical and pro forma financial information,
along with all other financial and other information, contained in or
otherwise incorporated by reference into this Prospectus, prior to tendering
their Notes in the Exchange Offer.
 
                                      ii

  The Exchange Offer. The Notes were originally offered and sold by TSAT (the
"Notes Offering") on February 20, 1997, in transactions not registered under
the Securities Act in reliance upon the exemption provided in Section 4(2) of
the Securities Act. The Notes were subsequently placed with qualified
institutional buyers, as defined in Rule 144A under the Securities Act, and
institutional "accredited investors," as defined in Rule 501(a)(1), (2), (3)
or (7) under the Securities Act, in reliance upon Rule 144A under the
Securities Act. Accordingly, the Notes may not be reoffered, resold or
otherwise transferred in the United States unless so registered or unless an
applicable exemption from the registration requirements of the Securities Act
is available. The Exchange Notes are being offered under the Exchange Offer in
order to satisfy certain obligations of TSAT under the Registration Rights
Agreements. See "The Exchange Offer."
 
  TSAT will accept for exchange pursuant to the Exchange Offer any and all
validly tendered Notes on or prior to 5:00 p.m., New York City time, on March
30, 1998, unless extended (the "Expiration Date"). Tenders of Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the
Expiration Date; otherwise such tenders are irrevocable. The Bank of New York
will act as exchange agent (in such capacity, the "Exchange Agent") in
connection with the Exchange Offer. The Exchange Offer is not conditioned upon
any minimum principal amount of Notes being tendered for exchange, but is
otherwise subject to certain customary conditions.
 
  Based on an interpretation by the staff of the SEC set forth in no-action
letters issued to third parties, TSAT believes that Exchange Notes issued
pursuant to the Exchange Offer may be offered for resale, resold and otherwise
transferred by a holder who is not an affiliate of TSAT without compliance
with the registration and prospectus delivery provisions of the Securities
Act, provided that the holder 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 (within the meaning of the Securities Act) of
the Exchange Notes. Persons wishing to exchange Notes in the Exchange Offer
must represent to TSAT that such conditions have been met.
 
  Broker-dealers who have acquired Notes directly from TSAT are not permitted
to exchange such Notes in the Exchange Offer.
 
  Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of Exchange Notes. The Letter of Transmittal states
that by so acknowledging and by delivering a prospectus, a broker-dealer will
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of
Exchange Notes received in exchange for Notes where such Notes were acquired
by such broker-dealer as a result of market-making activities or other trading
activities. TSAT has agreed that, for a period of 180 days after the date of
this Prospectus, it will use its commercially reasonably best efforts to make
this Prospectus, as so amended or supplemented, available to any broker-dealer
for use in connection with any such resale.
 
  TSAT does not intend to list the Exchange Notes on any national securities
exchange or to seek the admission thereof to trading in the National
Association of Securities Dealers Automated Quotation System. As a result,
TSAT cannot determine whether an active public market will develop for the
Exchange Notes. TSAT has common stock listed on the Nasdaq National Market
tier of the Nasdaq Stock Market (the "Nasdaq National Market") under the
symbols "TSATA" and "TSATB." It is expected that, if the TSAT Merger is
consummated, shares of New PRIMESTAR Class A Common Stock and New PRIMESTAR
Class B Common Stock will be authorized for listing, subject to official
notice of issuance, on the Nasdaq National Market.
 
  Any Notes not tendered and accepted in the Exchange Offer will remain
outstanding. To the extent that any Notes are tendered and accepted in the
Exchange Offer, a holder's ability to sell untendered Notes could be adversely
affected. Following consummation of the Exchange Offer, the holders of Notes
will continue to be subject to the existing restrictions upon transfer thereof
and the Borrower will have no further obligation to such holders to provide
for the registration under the Securities Act of the Notes held by them. See
"The Exchange Offer--Consequences of Failure to Exchange."
 
                                      iii

  TSAT expects that the Exchange Notes issued pursuant to the Exchange Offer
generally will be issued in the form of Global Exchange Notes (as defined
herein), which will be deposited with, or on behalf of, The Depository Trust
Company (the "Depository") and registered in its name or in the name of Cede &
Co., its nominee. Beneficial interests in the Global Exchange Notes
representing the Exchange Notes will be shown on, and transfers thereof will
be effected through, records maintained by the Depository and its
participants. Notwithstanding the foregoing, Notes held in certificated form
will be exchanged solely for Exchange Notes in certificated form. After the
initial issuance of the Global Exchange Notes, Exchange Notes in certificated
form will be issued in exchange for the Global Exchange Notes on the terms set
forth in the Indentures. See "Description of the Exchange Notes--Form,
Denomination and Book-Entry Procedures."

                                  THE BORROWER
 
TSAT
 
  General. TSAT is a leading distributor of digital satellite-based television
services in the United States. TSAT markets and distributes the PRIMESTAR(R)
programming service ("PRIMESTAR(R)"), a medium power digital satellite service,
under the brand names "PRIMESTAR By TCI" and "PRIMESTAR By TSAT" and owns an
aggregate 20.86% interest in the Partnership, which owns and operates the
PRIMESTAR(R) service. As of September 30, 1997, TSAT was the largest
distributor of PRIMESTAR(R), with an installed base of approximately 769,000
subscribers, which represented approximately 42.7% of the Partnership's
estimated 1.8 million subscribers as of such date. As of September 30, 1997,
TSAT's subscribers comprised approximately 888,000 Authorized Units. As used
herein, the term "Authorized Units" refers to the number of active authorized
satellite receivers or integrated receiver/decoders ("IRDs"), more than one of
which may be installed in a subscribing household. PRIMESTAR(R) offers over 160
channels of digital video and audio programming throughout the continental
U.S., via medium power satellite, to home satellite dishes ("dishes" or "HSDs")
approximately 27 to 36 inches in diameter for most subscribers.
 
  TSAT was incorporated in Delaware in November 1996. Prior to the Spin-off
Date, TSAT was a wholly-owned subsidiary of TCI, which, through various
subsidiaries, was engaged in the business of distributing PRIMESTAR(R) since
December 1990. TSAT was formed to own and operate TCI's interests in the
digital satellite business, in connection with the distribution (the "TSAT
Spin-off") by TCI to certain of its stockholders on the Spin-off Date of all
the issued and outstanding shares of TSAT Common Stock, to own and operate
certain businesses of TCI, constituting all of TCI's interests in the digital
satellite business. TSAT's predecessor was incorporated in February 1995 to
consolidate TCI's PRIMESTAR(R) distribution business into one subsidiary, and
was merged into TSAT in connection with the TSAT Spin-off. TCI is one of the
two largest operators of cable systems in the U.S.
 
  TSAT Series A Common Stock and TSAT Series B Common Stock trade on the Nasdaq
National Market under the symbols "TSATA" and "TSATB," respectively. The
mailing address and telephone number of TSAT's principal executive offices are
8085 South Chester, Suite 300, Englewood, Colorado 80112, (303) 712-4600.
 
  Tempo. Tempo Satellite, Inc. ("Tempo"), a wholly-owned subsidiary of TSAT,
holds a construction permit issued by the FCC, authorizing construction of a
high power direct broadcast satellite ("DBS") system
 
                                       1
<PAGE>
 
consisting of two or more satellites delivering DBS service in 11 frequencies
at the 119(degrees) West Longitude ("W.L.") orbital position and 11 frequencies
at the 166(degrees) W.L. orbital position (the "FCC Permit"). The 119(degrees)
W.L. orbital position is one of three such orbital positions available for DBS
service to the U.S. which are "full CONUS," meaning that they have a view of
the entire continental U.S.
 
  Tempo is also a party to a satellite construction agreement with Space
Systems/Loral, Inc. ("Loral"), dated as of February 22, 1990 (the "Satellite
Construction Agreement"), pursuant to which Tempo has arranged for the
construction of two high power direct broadcast satellites (together, the
"Tempo Satellites") and has an option to purchase up to three additional
satellites. Construction of the Tempo Satellites has been completed. One of the
Tempo Satellites ("Tempo DBS-1") was launched into TSAT's high power slot at
119(degrees) W.L. on March 8, 1997. The other Tempo Satellite ("Tempo DBS-2")
presently serves as a ground spare for Tempo DBS-1.
 
  Tempo DBS-1 is currently undergoing extended in-orbit testing under the
Satellite Construction Agreement. Assuming that such in-orbit testing results
in acceptance of the satellite by Tempo under the Satellite Construction
Agreement, Tempo DBS-1 would be available for commercial operations in the
first quarter of 1998. At current levels of digital compression, Tempo believes
that Tempo DBS-1 would be able to deliver approximately 100 channels of digital
video and 20 channels of digital audio programming, as operated under the FCC
Permit. Tempo expects to use 18 inch dishes for the proposed high power
service, the same diameter currently used by other high power DBS providers, in
most areas. Tempo currently intends to operate Tempo DBS-1 as a platform to
provide high power digital video and audio programming services to residential
customers, as well as multiple dwelling units ("MDUs"), commercial customers
and resellers.
 
  The availability and utility of Tempo DBS-1, including the power levels
provided by Tempo DBS-1, are subject to risks of satellite defect, loss or
reduced performance. Since the launch of Tempo DBS-1, Loral has notified Tempo
of at least five separate occurrences of power reductions on Tempo DBS-1. No
assurance can be given that further power reductions will not occur in the
future. TSAT does not currently know the extent of such power reductions, and
cannot confirm the precise causes thereof; however, such reductions could
eventually affect the proposed operation of Tempo DBS-1, either alone or
together with other events that may arise during the expected life of the
satellite. See "Risk Factors--Risks of Satellite Failure."
 
  Pursuant to an option agreement dated February 8, 1990 between Tempo and the
Partnership (the "Tempo Option Agreement"), Tempo has agreed to sell or lease
to the Partnership 100% of the capacity of any DBS system constructed by Tempo
under the FCC Permit. The capital stock of Tempo is excluded from the assets
that TSAT will be transferring to New PRIMESTAR pursuant to the Restructuring
Transaction, and accordingly, upon consummation of the Restructuring
Transaction, Tempo shall remain a wholly owned subsidiary of TSAT. Tempo is not
a Restricted Subsidiary under the Indentures (as such term is defined therein).
If the TSAT Merger or the Tempo Sale (as defined herein) is consummated, then
New PRIMESTAR shall acquire the capital stock or the assets of Tempo and New
PRIMESTAR will operate Tempo's high power DBS system. Otherwise, TSAT expects
that such system will be utilized by the Partnership (which, after the
Restructuring Transaction, will be a wholly owned subsidiary of New PRIMESTAR)
pursuant to the Tempo Option Agreement. See "Risk Factors--Uncertainty
Regarding High Power Strategies"; "The Roll-up Plan."
 
OTHER RESTRUCTURING PARTIES
 
  The Partnership. The Partnership owns and operates PRIMESTAR(R), which is the
oldest Ku-band satellite television service in the U.S. and has the second
largest subscriber base of any U.S. digital satellite television service. In
1990, direct or indirect subsidiaries of TCI and several other large cable
operators and GE Americom Services, Inc. ("GEAS"), an indirect subsidiary of
General Electric ("GE"), formed the Partnership to acquire, originate and/or
provide television programming services for delivery by satellite to
subscribers in the continental U.S. Initially, PRIMESTAR(R) was an analog
service limited to seven broadcast television superstations, TV Japan
 
                                       2
<PAGE>
 
and three pay-per-view stations. In 1994, PRIMESTAR(R) was among the first
satellite television services to use digital transmission and compression
technology to offer laser-disc-quality image and compact-disc-quality sound.
The Partnership has consistently taken advantage of technological improvements
and additional available transponder capacity to improve the PRIMESTAR(R)
service, which today offers over 160 channels of digital video and audio
programming.
 
  In addition to TSAT, the partners (the "Partners") in the Partnership include
(i) Cox Satellite, Inc. ("Cox SI"), a subsidiary of Cox Communications, Inc.
("Cox"), (ii) Comcast DBS, Inc. ("Comcast DBS"), a subsidiary of Comcast
Corporation ("Comcast"), (iii) Continental Satellite Company, Inc.
("Continental"), a subsidiary of US WEST, Inc., the parent of MediaOne of
Delaware, Inc. ("MediaOne"), (iv) New Vision Satellite, a partnership
controlled by Advance/Newhouse Parntership ("Newhouse"), which is a subsidiary
of Newhouse Broadcasting Corporation ("Newhouse Broadcasting"), (v) TW
Programming Co., a partnership controlled by Time Warner Entertainment Company,
L.P. ("TWE"), which is a subsidiary of Time Warner Inc. ("Time Warner"), and
(vi) GEAS, a subsidiary of GE, the parent of GE American Communications, Inc.
("GE Americom"). Each of TSAT (through its subsidiaries) and TW Programming Co.
holds a 20.86% Partnership Interest (as defined), each of Cox SI, Comcast DBS,
Continental and New Vision Satellite holds a 10.43% Partnership Interest, and
GEAS holds a 16.56% Partnership Interest. Time Warner has substantial
interests, through its subsidiaries and controlled partnerships, in video
programming and distribution, and is one of the two largest operators of cable
systems in the U.S. Cox, Comcast and MediaOne are also among the five largest
cable system operators.
 
  The PRIMESTAR(R) programming service includes a variety of advertiser-
supported networks (sometimes referred to as "basic cable" channels), a broad
selection of movie services, national and regional sports packages and other
premium services, and multiplexed pay-per-view programming. The Partnership
secures its rights to transmit such programming via satellite by entering into
non-exclusive affiliation agreements with programming vendors. In addition to
video services, PRIMESTAR(R) includes digital audio and data services,
including Ingenius, which provides access to news, business news, stock quotes,
sports, weather and entertainment information to subscribers through their
personal computers.
 
  The Partnership currently plans to participate in the high power segment of
the digital satellite industry. In that connection, the Partnership has agreed
to purchase or lease from Tempo 100% of the capacity of any DBS system
constructed by Tempo under the FCC Permit. In addition, the Partnership has
entered into the ASkyB Agreement, which provides for the sale and transfer to
New PRIMESTAR of the MCI Satellites (as defined herein), certain authorizations
granted to MCI by the FCC to operate a DBS business at the 110(degrees) W.L.
orbital location using 28 transponder channels, and certain related contracts.
The ASkyB Agreement requires New PRIMESTAR to bear certain risks in connection
with the process of obtaining the regulatory approval related to such
transfers, including the divestiture of all rights of the Partnership and any
of the Partners under Tempo's FCC authorizations with respect to the 11
transponder channels at 119(degrees) W.L., if required as a condition to such
approval. Consummation of the ASkyB Transaction is contingent on, among other
things, receipt of all necessary government and regulatory approvals, and
accordingly, no assurance can be given that the ASkyB Transaction will be
consummated. See "Recent Transactions--The ASkyB Transaction."
 
  The mailing address and telephone number of the Partnership's principal
executive offices are 3 Bala Plaza West, Suite 700, Bala Cynwyd, Pennsylvania
19004, (610) 617-5300.
 
  Other PRIMESTAR(R) Distributors. PRIMESTAR(R) is distributed through TSAT and
the other distributors of PRIMESTAR(R) (the "Distributors"), each of which is
currently affiliated with one or more of the Partners. The Distributors market
the PRIMESTAR(R) service and contract with subscribers, in non-exclusive
territories assigned by the Partnership. The Distributors set their own retail
pricing and are responsible in their respective territories for authorization
of subscribers, installation, maintenance and retrieval of customer premises
equipment, and billing and collection of monthly and other fees, and the
Distributors bear all risks of loss relating
 
                                       3
<PAGE>
 
thereto. The Partnership performs certain administrative functions for the
Distributors, including program acquisition, national marketing, transponder
leasing and certain technical functions, and passes along the costs relating
thereto to the Distributors.
 
  New PRIMESTAR. New PRIMESTAR, a newly formed Delaware corporation, is
currently a wholly-owned subsidiary of TSAT that has not conducted any
significant activities other than those incident to its formation, the
execution of the agreements relating to the Restructuring Transaction to which
it is a party and financing activities relating to the Restructuring
Transaction. As a result of the Restructuring Transaction, PRIMESTAR will
acquire all the assets and liabilities of TSAT other than the capital stock of
Tempo and certain agreements, the interests in the Partnership ("Partnership
Interests") of the other Partners and the PRIMESTAR(R) subscribers and related
assets and liabilities of the other Distributors. It is expected that, measured
by the number of subscribers, New PRIMESTAR will be the second largest provider
of satellite television services in the United States. The mailing address and
the telephone number of New PRIMESTAR's principal executive offices are 8085
South Chester, Suite 300, Englewood Colorado 80122, (303) 712-4600.
 
ROLL-UP PLAN
 
  Restructuring Transaction. On February 6, 1998, TSAT entered into (i) a
Merger and Contribution Agreement dated as of February 6, 1998 (together with
exhibits and schedules thereto, the "Restructuring Agreement"), among TSAT, New
PRIMESTAR, TWE, Newhouse, Comcast, Cox, MediaOne (together with TWE, Newhouse,
Comcast and Cox, collectively, hereinafter referred to as the "Series C
Stockholders") and GE Americom, and (ii) an Asset Transfer Agreement dated as
of February 6, 1998 (together with the exhibits and schedules thereto, the
"TSAT Asset Transfer Agreement"), between TSAT and New PRIMESTAR. In addition,
on February 6, 1998, TSAT entered into the TSAT Merger Agreement, between TSAT
and New PRIMESTAR, pursuant to which TSAT shall merge with and into New
PRIMESTAR, with New PRIMESTAR as the surviving corporation. The TSAT Merger
Agreement is subject to regulatory approval and other closing conditions set
forth in the TSAT Merger Agreement. The transactions contemplated under the
Restructuring Agreement and the TSAT Asset Transfer Agreement comprise the
Restructuring Transaction, which, if consummated, shall result in New
PRIMESTAR's owning the entire PRIMESTAR(R) digital satellite business. Upon
consummation of the Restructuring Transaction, TSAT and its former Partners (or
their respective affiliates) will, in the aggregate, own all the outstanding
capital stock of New PRIMESTAR.
 
  Pursuant to the Restructuring Agreement and the TSAT Asset Transfer
Agreement, upon the terms and subject to the conditions set forth therein, TSAT
will contribute and transfer to New PRIMESTAR all of TSAT's assets and
liabilities (the "TSAT Business"), except (i) the capital stock of Tempo, a
wholly-owned subsidiary of TSAT that holds certain authorizations granted by
the FCC and other assets and liabilities relating to a proposed direct
broadcast system being constructed by Tempo, (ii) the consideration to be
received by TSAT in the Restructuring Transaction and (iii) the rights and
obligations of TSAT under certain agreements. Accordingly, upon consummation of
the Restructuring Transaction and the effectiveness of the Assumption, TSAT's
obligations under the Notes and the Exchange Notes shall be assumed by New
PRIMESTAR.
 
  In addition, upon the terms and subject to the conditions set forth in the
Restructuring Agreement, each of Comcast DBS, Comcast Satellite Communications,
Inc. ("Comcast SCI" and, together with Comcast DBS, "Comcast Satellite"), Cox
SI and GEAS, respectively, will merge with and into New PRIMESTAR, in
accordance with the terms and subject to the conditions of its respective
Merger Agreement, and New PRIMESTAR will be the surviving corporation of each
such Merger. Pursuant to asset transfer agreements, each of TWE, Newhouse and
MediaOne (and its subsidiaries) will assign and transfer to New PRIMESTAR all
of such party's rights, title and interests in, to and under such party's
Partnership Interest and PRIMESTAR Assets, and New PRIMESTAR will assume all of
such party's PRIMESTAR Liabilities (as defined herein).
 
  Under the terms of the Restructuring Agreement, TSAT will own approximately
36% of the outstanding shares of common equity of New PRIMESTAR at the closing
of the Restructuring Transaction, and TWE and
 
                                       4
<PAGE>
 
Newhouse (collectively), Comcast, MediaOne, Cox and GE Americom will own
approximately 31%, 10%, 9%, 9% and 5%, respectively, of the outstanding shares
of common equity of New PRIMESTAR at closing, subject in each case to
adjustments based on closing subscriber counts.
 
  The TSAT Merger. The Restructuring Transaction comprises the first step in
TSAT's proposed two-step Roll-up Plan. The second step of the Roll-up Plan
consists of the TSAT Merger, pursuant to which TSAT shall merge with and into
New PRIMESTAR, with New PRIMESTAR as the surviving corporation, in accordance
with the TSAT Merger Agreement. It is expected that the TSAT Merger shall be
consummated after the consummation of the Restructuring Transaction.
Consummation of the Restructuring Transaction and the TSAT Merger are subject
to approval of the stockholders of TSAT. TSAT has called a special meeting of
its stockholders, to be held on March 6, 1998, to consider and vote upon the
Restructuring Transaction and the TSAT Merger. In addition, TSAT Merger is
subject to regulatory approval and other closing conditions set forth in the
TSAT Merger Agreement; accordingly, although the Roll-up Plan envisions that
the TSAT Merger will be consummated upon consummation of the Restructuring
Transaction, there can be no assurance that the TSAT Merger will be
consummated, even if the Restructuring Transaction is consummated.
 
  In connection with the TSAT Merger (i) each outstanding share of TSAT Series
A Common Stock will be converted into the right to receive one share of Class A
Common Stock of New PRIMESTAR, par value of $.01 per share ("New PRIMESTAR
Class A Common Stock") and (ii) each outstanding share of TSAT Series B Common
Stock will be converted into the right to receive one share of Class B Common
Stock of New PRIMESTAR, par value of $.01 per share ("New PRIMESTAR Class B
Common Stock"). Each share of New PRIMESTAR's common stock then held by TSAT
will be canceled. As a result of the TSAT Merger, stockholders of TSAT, at
closing, will own approximately 34% of the outstanding shares of New PRIMESTAR
Common Stock.
 
                                  RISK FACTORS
 
  In reviewing this Prospectus, holders of the Notes should carefully consider
the matters described under the heading "Risk Factors" beginning on page 23.
 
                               THE NOTES OFFERING
 
The Notes.................  The Notes were sold by the Borrower on February 20,
                            1997, pursuant to the Notes Offering and were
                            subsequently resold to qualified institutional
                            buyers (as defined in Rule 144A under the
                            Securities Act) and institutional "accredited
                            investors" (as defined in Rule 501(a)(1), (2), (3)
                            or (7) under the Securities Act), pursuant to Rule
                            144A under the Securities Act. As of the date
                            hereof, there are $200,000,000 aggregate principal
                            amount of Senior Subordinated Notes and
                            $275,000,000 aggregate principal amount at maturity
                            of Senior Subordinated Discount Notes outstanding.
                            The aggregate net proceeds from the issuance of the
                            Notes (approximately $340 million after deducting
                            offering costs) were initially held in escrow and
                            were subsequently released to TSAT on March 17,
                            1997. TSAT used $244 million of such net proceeds
                            to repay amounts outstanding under the Bank Credit
                            Facility. Maximum commitments under the Bank Credit
                            Facility ($750 million at December 31, 1997) are
                            reduced quarterly commencing March 31, 2001 until
                            final maturity at June 30, 2005. Amounts
                            outstanding under the Bank Credit Facility accrue
                            interest at a variable rate of interest, which, at
                            December 31, 1997, was equal to 7.2%.

                            The Senior Subordinated Notes were issued at par.
                            The Senior Subordinated Discount Notes were issued
                            at a discount to their aggregate principal amount
                            at maturity, with a yield to maturity calculated
                            from the issuance date of 12 1/4% (computed on a
                            semi-annual bond equivalent basis).
 
Registration Rights         In connection with the Notes Offering, the Borrower
 Agreements...............  entered into the Registration Rights Agreements,
                            which grant the holders of the Notes certain
                            exchange and registration rights.
 
                            The Exchange Offer is intended to satisfy such
                            exchange and registration rights, which terminate
                            upon the consummation of the Exchange Offer. TSAT
                            shall not receive any proceeds from the Exchange
                            Offer, but pursuant to the Registration Rights
                            Agreement, TSAT shall bear certain expenses
                            relating to the Exchange Offer.
 
                               THE EXCHANGE OFFER
 
Securities Offered........  $200,000,000 aggregate principal amount of 10 7/8%
                            Senior Subordinated Notes due February 15, 2007 and
                            $275,000,000 aggregate principal amount at maturity
                            of 12 1/4% Senior Subordinated Discount Notes due
                            February 15, 2007.
 
The Exchange Offer........  $1,000 principal amount of the Senior Subordinated
                            Exchange Notes in exchange for each $1,000
                            principal amount of Senior Subordinated Notes, and
                            $1,000 principal amount at maturity of the Senior
                            Subordinated Discount Exchange Notes in exchange
                            for each $1,000 principal amount at maturity of
                            Senior Subordinated Discount Notes. The Borrower
                            will issue the Exchange Notes to holders on or
                            promptly after the Expiration Date.
 
                            Based on an interpretation by the staff of the SEC
                            set forth in no-action letters issued to third
                            parties, the Borrower believes that Exchange Notes
                            issued pursuant to the Exchange Offer in exchange
                            for Notes may be offered for resale, resold and
                            otherwise transferred by any holder thereof (other
                            than any such holder which is an "affiliate" of the
                            Borrower within the meaning of Rule 405 under the
                            Securities Act) without compliance with the
                            registration and prospectus delivery provisions of
                            the Securities Act, provided that such Exchange
                            Notes are acquired in the ordinary course of such
                            holder's business and that such holder does not
                            intend to participate and has no arrangement or
                            understanding with any person to participate in the
                            distribution of such Exchange Notes.
 
                            Broker-dealers who have acquired Notes directly
                            from TSAT are not permitted to exchange such Notes
                            in the Exchange Offer.
 
                            Each broker-dealer that receives Exchange Notes for
                            its own account pursuant to the Exchange Offer must
                            acknowledge that it will deliver a prospectus in
                            connection with any resale of such Exchange Notes.
                            The Letter of Transmittal states that by so
                            acknowledging and by delivering
 
                                       6
<PAGE>
 
                            a prospectus, a broker-dealer will not be deemed to
                            admit that it is an "underwriter" within the
                            meaning of the Securities Act. This Prospectus, as
                            it may be amended or supplemented from time to
                            time, may be used by a broker-dealer in connection
                            with resales of Exchange Notes received in exchange
                            for Notes where such Notes were acquired by such
                            broker-dealer as a result of market-making
                            activities or other trading activities. The
                            Borrower has agreed that, for a period of 180 days
                            after the Expiration Date, the Borrower will make
                            this Prospectus available to any broker-dealer for
                            use in connection with any such resale.
 
                            Any holder who tenders in the Exchange Offer with
                            the intention to participate, or for the purpose of
                            participating, in a distribution of the Exchange
                            Notes could not rely on the position of the staff
                            of the SEC enunciated in Exxon Capital Holdings
                            Corporation (available April 13, 1989), Morgan
                            Stanley & Co., Inc. (available June 5, 1991) or
                            similar no-action letters and, in the absence of an
                            exemption therefrom, must comply with the
                            registration and prospectus delivery requirements
                            of the Securities Act in connection with the resale
                            transaction. Failure to comply with such
                            requirements in such instance may result in such
                            holder incurring liability under the Securities Act
                            for which the holder is not indemnified by the
                            Borrower.
 
Expiration Date...........
                            5:00 p.m., New York City time, on March 30 1998,
                            unless the Exchange Offer is extended, in which
                            case the term "Expiration Date" means the latest

                            rights and subject to all the limitations
                            applicable thereto under the Indentures, except to

                            result of the Exchange Offer. All untendered Notes

                            market, if any, for the untendered Notes could be
                            adversely affected.

                       SUMMARY OF TERMS OF EXCHANGE NOTES
 
  The Exchange Notes are substantially identical with respect to their form and
the terms contained therein (including principal amounts, interest rate,
maturity and redemption rights) to the Notes for which they may be exchanged
pursuant to the Exchange Offer, except that (i) the offering and sale of the
Exchange Notes has been registered under the Securities Act and, therefore, the
Exchange Notes will not bear certain legends restricting the transfer thereof
and (ii) the holders of Exchange Notes will not be entitled to further
registration rights under the Registration Rights Agreements, which rights will
be satisfied when the Exchange Offer is consummated. Each tranche of the
Exchange Notes will be issued as a separate series of notes pursuant to the
same Indenture governing the corresponding tranche of Notes for which such
tranche of Exchange Notes will be exchanged, which Indenture will be qualified
under the TIA. Holders of the Exchange Notes will be entitled to substantially
identical benefits under the Indentures (other than such changes as are
necessary to comply with any requirements of the SEC to effect or maintain the
qualification of such trust indenture under the TIA). See "Description of the
Exchange Notes."

                            among other things, limit the ability of the
                            Borrower and its Restricted Subsidiaries (as
                            defined) to incur additional Indebtedness (as
                            defined), create certain Liens (as defined), make

                            The Exchange Notes will rank junior to, and be
Ranking...................  subordinated in right of payment to, all existing
                            and future Senior Indebtedness (as defined) of the
                            Borrower, pari passu in right of payment with all
                            senior subordinated Indebtedness of the Borrower
                            and senior in right of payment to all Subordinated
                            Indebtedness (as defined) of the Borrower. As of
                            December 31, 1997, the Borrower had approximately
                            $79,949,000 of Senior Indebtedness outstanding, of
                            which $48,000,000 represented borrowings under the
                            Bank Credit Facility. The Borrower will not be
                            permitted to incur any debt that is subordinated in
                            right of payment to any Senior Indebtedness of the
                            Borrower and senior in right of payment to the
                            Exchange Notes and Notes. See "Risk Factors--
                            Subordination of the Exchange Notes" and
                            "Description of the Exchange Notes--Subordination
                            of the Exchange Notes." All borrowings under the
                            Bank Credit Facility are guaranteed on a senior
                            basis by all direct and indirect subsidiaries of
                            the Borrower other than Tempo. The Exchange Notes
                            will not be entitled to the benefit of any
                            guarantees, except under the circumstances
                            described under "Description of the Exchange
                            Notes--Certain Covenants--Limitation on
                            Indebtedness."
 
Security..................  The Notes are not, and the Exchange Notes will not
                            be, entitled to any security.
 
                  RECENT TRANSACTIONS--THE ASKYB TRANSACTION.
 
  In a separate proposed transaction (the "ASkyB Transaction"), pursuant to an
asset acquisition agreement, dated as of June 11, 1997 (together with the
exhibits and schedules thereto, and as amended from time to time, the "ASkyB
Agreement") among the Partnership, The News Corporation Limited ("News Corp."),
MCI Telecommunications Corporation, the principal domestic operating subsidiary
of MCI Communications Corporation ("MCI"), American Sky Broadcasting LLC, a
wholly-owned subsidiary of News Corp. ("ASkyB"), and for certain purposes only,
each of the partners of the Partnership (collectively, the "Partners"), New
PRIMESTAR will acquire from MCI, News Corp. and ASkyB, as applicable, two high
power communications satellites currently under construction (the "MCI
Satellites"), certain authorizations granted to MCI by the FCC to operate a DBS
business at the 110(degrees) W.L. orbital location using 28 transponder
channels, and certain related contracts. In consideration, ASkyB will receive
non-voting convertible securities of New PRIMESTAR, comprising, subject to
closing adjustments, approximately $600 million liquidation value of non-voting
convertible preferred stock, $.01 par value per share, of New PRIMESTAR (the
"New PRIMESTAR Convertible Preferred Stock") (convertible into approximately 52
million shares of non-voting Class D Common Stock, $.01 par value per share, of
New PRIMESTAR ("New PRIMESTAR Class D Common Stock"), subject to adjustment)
and approximately $516 million principal amount of convertible subordinated
notes of New PRIMESTAR ("New PRIMESTAR Convertible Subordinated Notes")
(convertible into approximately 45 million shares of New PRIMESTAR Class D
Common Stock).
 
  The New PRIMESTAR Convertible Subordinated Notes will be due and payable, and
the New PRIMESTAR Convertible Preferred Stock will be mandatorily redeemable,
on the tenth anniversary of the date of issuance. The New PRIMESTAR Convertible
Preferred Stock will accrue cumulative dividends at the annual rate of 5% of
the liquidation value of such shares and the New PRIMESTAR Convertible
Subordinated Notes will have an interest rate of 5%. Dividends on the New
PRIMESTAR Convertible Preferred Stock and interest on the New PRIMESTAR
Convertible Subordinated Notes will be payable in cash or, at the option of New
PRIMESTAR, in shares of the non-voting New PRIMESTAR Class D Common Stock, for
a period of four years.
 
                                       12
<PAGE>
 
Thereafter, all dividend and interest payments will be made solely in cash.
Shares of New PRIMESTAR Class D Common Stock issued to ASkyB or any of its
affiliates upon conversion of such New PRIMESTAR Convertible Preferred Stock
and New PRIMESTAR Convertible Subordinated Notes, or in payment of dividend or
interest obligations thereunder, will in turn automatically convert into shares
of New PRIMESTAR Class A Common Stock, on a one-to-one basis, upon transfer to
any person other than ASkyB, News Corp. or any of their respective affiliates.
Assuming such a transfer and conversion, and based on the number of shares of
New PRIMESTAR Common Stock (as defined below) expected to be issued in the
Restructuring Transaction (subject to adjustment as provided in the
Restructuring Agreement, the New PRIMESTAR Class D Common Stock into which the
New PRIMESTAR Convertible Subordinated Notes and the New PRIMESTAR Convertible
Preferred Stock are convertible, would be converted into New PRIMESTAR Class A
Common Stock representing approximately 33% of the number of shares of New
PRIMESTAR Common Stock and approximately 20% of the combined voting power of
the New PRIMESTAR Common Stock outstanding after giving effect to such a
transfer and conversion.
 
  Consummation of the ASkyB Transaction is contingent on, among other things,
receipt of all necessary government and regulatory approvals, and accordingly,
no assurance can be given that the ASkyB Transaction will be consummated. In
addition, it is a condition precedent to the closing of the ASkyB Transaction
by New PRIMESTAR that the ASkyB Transaction be approved by the holders of New
PRIMESTAR voting common stock, including the former holders of TSAT Common
Stock if the TSAT Merger shall have been consummated, at an annual or special
meeting of New PRIMESTAR. The ASkyB Agreement provides that if the
Restructuring Transaction has not closed by March 8, 1998, and the closing
conditions set forth in the ASkyB Agreement have all been satisfied, then News
Corp., MCI and ASkyB (collectively, the "ASkyB Transferors") will have the
right to transfer to the Partnership the assets contemplated to be transferred
to New PRIMESTAR under the ASkyB Transaction, in exchange for such
consideration, having an aggregate fair market value equal to the aggregate
consideration that would have been received by the ASkyB Transferors pursuant
to the ASkyB Transaction had the Restructuring Transaction closed by such date,
as the Partnership and the ASkyB Transferors shall mutually agree.

(1) Revenue of TSAT, TWSSI, Cox Satellite, Comcast Satellite and MediaOne
    Satellite is primarily comprised of installation and monthly service
    revenue received from subscribers to the PRIMESTAR(R) service. The
    Partnership derives its revenue by providing satellite capacity and
    programming, national marketing and distribution services to the
    Distributors.
(2) Operating Cash Flow (deficit), which represents operating income (loss)
    before depreciation, amortization and stock compensation, is a commonly
    used measure of value and borrowing capacity within the direct broadcast
    satellite industry, and is not intended to be a measure of performance in
    accordance with generally accepted accounting principles and should not be
    relied on as such. Furthermore, Operating Cash Flow (deficit) may not be
    comparable to similarly titled measures reported by other companies.
    Operating Cash Flow (deficit) should be viewed in conjunction with cash
    flows measured in accordance with generally accepted accounting principles.
    For information concerning such cash flows, see "MANAGEMENT'S DISCUSSION
    AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS--Liquidity
    and Capital Resources" of TSAT, TWSSI, Cox Satellite, Comcast Satellite,
    MediaOne Satellite and the Partnership, and the statements of cash flows
    included in the historical financial statements of TSAT, TWSSI, Cox
    Satellite, Comcast Satellite, MediaOne Satellite and the Partnership, which
    are incorporated by reference in this Prospectus.

                                 RISK FACTORS
 
  Prospective holders of the Exchange Notes should pay careful attention to
the following factors in addition to considerations bearing on their
individual situations and the other information contained or incorporated by
reference herein. The following factors should be read in conjunction with,
and are qualified in their entirety by, the financial, business and other
information set forth in the financial statements and other documents
incorporated by reference in this Prospectus, including, among other things,
the information relating to the Roll-up Plan included in TSAT's Current Report
of Form 8-K dated February 11, 1998. See "Available Information" and
"Incorporation of Certain Documents By Reference" for information concerning
such documents incorporated by reference herein or to obtain copies of such
documents.
 
HISTORY OF LOSSES OF TSAT AND OTHER RESTRUCTURING PARTIES
 
  TSAT has had a limited history as a separate operating entity. From 1990 to
1995, TCI's business of distributing PRIMESTAR(R) was operated by TCIC, the
subsidiary of TCI that owns and operates cable systems in the U.S., and during
this period of time, such business sustained significant operating losses.
TSAT has similarly sustained significant losses in recent periods. TSAT's
operating losses were $122,748,000, $81,266,000, $184,284,000, $60,702,000 and
$9,144,000 for the nine months ended September 30, 1997 and 1996, and the
years ended December 31, 1996, 1995 and 1994, respectively, and TSAT's net
losses in such periods were $166,544,000, $56,594,000, $140,004,000,
$47,507,000 and $13,688,000, respectively. Each of the other parties to the
Restructuring Transaction have also sustained losses in their PRIMESTAR(R)-
related businesses. On a pro forma basis, after giving effect to the
Restructuring Transaction, the TSAT Merger and the ASkyB Transaction, New
PRIMESTAR would have had operating losses of $331,453,000 and $470,809,000,
for the nine months ended September 30, 1997 and the year ended December 31,
1996, respectively, and net losses attributable to common stockholders in such
periods of $395,112,000 and $414,184,000, respectively. See the Primary and
Supplemental Condensed Pro Forma Combined Financial Statements and notes
thereto of New PRIMESTAR, incorporated by reference herein. Improvements in
results of operations of the Borrower are largely dependent upon its ability
to increase its customer base while maintaining its price structure, reducing
the rate at which subscribers terminate their PRIMESTAR(R) service ("churn")
and effectively managing its costs. No assurance can be given that any such
improvements will occur. In addition, TSAT incurs, and New PRIMESTAR will
incur, significant sales commission and installation costs when its customers
initially subscribe to the service. Management expects that the costs of
acquiring subscribers will continue to be significant so long as a rapid
growth rate is maintained. The high cost of obtaining new subscribers also
magnifies the negative effects of subscriber churn. See "--Ability to Manage
Growth; Subscriber Churn."
 
  Upon consummation of the Restructuring Transaction, the TSAT Business will
be consolidated into New PRIMESTAR. New PRIMESTAR will be a significantly
larger entity than TSAT, and it is anticipated that New PRIMESTAR will
initially incur significantly greater losses than TSAT due primarily to
disproportionately higher levels of depreciation, amortization and interest
expense. In addition, New PRIMESTAR intends to develop a high power DBS
service, and New PRIMESTAR may determine to migrate some or all of the
existing PRIMESTAR(R) medium power customers to such high power service. Under
such circumstances, New PRIMESTAR would necessarily be operating under a
different cost structure than that of the TSAT Business.
 
LACK OF OPERATING HISTORY OF NEW PRIMESTAR
 
  New PRIMESTAR has had no operating history as a combined operating entity.
Since 1990, the business of operating the PRIMESTAR(R) satellite television
service has been owned and operated by the Partnership, and the businesses of
distributing PRIMESTAR(R) in various territories have been separately operated
by the Distributors. Following the Restructuring Transaction, the management
of New PRIMESTAR will have to integrate such separate businesses and to
develop and implement new business plans, policies, strategies and procedures
to operate the PRIMESTAR(R) business on a consolidated basis. Certain of such
plans, policies, strategies and procedures may be different from, or
additional to, the plans, policies, strategies and procedures utilized by the
Partnership and the Distributors separately prior to consummation of the
Restructuring
 
                                      23
<PAGE>
 
Transaction. Any material delay in developing and implementing such plans,
policies, strategies or procedures, or any other material difficulties that
may be experienced in connection with the integration of the PRIMESTAR(R)
businesses, could have a material adverse effect on the operations and results
of operations of New PRIMESTAR.
 
SUBSTANTIAL LEVERAGE; ADDITIONAL INDEBTEDNESS LIKELY
 
  TSAT is highly leveraged and, following consummation of the Restructuring
Transaction, New PRIMESTAR will be highly leveraged. As of September 30, 1997,
TSAT had approximately $366 million of debt (approximately $476 of debt per
subscriber), and on a pro forma basis, after giving effect to the
Restructuring Transaction, the TSAT Merger and the ASkyB Transaction, New
PRIMESTAR would have had approximately $1.9 billion of debt (approximately
$1,056 of debt per subscriber), including (i) an aggregate of $921 million of
debt of TSAT and the Partnership that would have been assumed by New PRIMESTAR
if the Restructuring Transaction had occurred on September 30, 1997, (ii) an
aggregate of $136 million of debt that would have been incurred by New
PRIMESTAR to fund the estimated cash that would have been paid to certain of
the Partners if the Restructuring Transaction had occurred on September 30,
1997, (iii) an aggregate of $328 million of debt that would have been incurred
by New PRIMESTAR to repay the estimated debt that would have been assumed from
certain of the Partners if the Restructuring Transaction had occurred on
September 30, 1997, and (iv) $516 million estimated principal amount of the
New PRIMESTAR Convertible Subordinated Notes that would have been issued by
New PRIMESTAR if the ASkyB Transaction had occurred on September 30, 1997. See
the historical financial statements and notes thereto of TSAT and the Primary
and Supplemental Condensed Pro Forma Combined Financial Statements and notes
thereto of New PRIMESTAR, incorporated by reference into this Prospectus.
 
  New PRIMESTAR will be a significantly larger entity than TSAT and will have
significant financial obligations. As described above, New PRIMESTAR will
incur or assume a significant amount of debt in connection with the
Restructuring Transaction (including the Notes and/or the Exchange Notes).
Upon consummation of the ASkyB Transaction, New PRIMESTAR will issue, subject
to closing adjustments, approximately $600 million liquidation value of New
PRIMESTAR Convertible Preferred Stock and $516 million aggregate principal
amount of New PRIMESTAR Convertible Subordinated Notes in connection with the
ASkyB Transaction. The New PRIMESTAR Convertible Subordinated Notes will be
due and payable, and the New PRIMESTAR Convertible Preferred Stock will be
mandatorily redeemable, on the tenth anniversary of the date of issuance. In
addition to the debt to be incurred and assumed in connection with the
Restructuring Transaction and the ASkyB Transaction, it is anticipated that
New PRIMESTAR will be required to seek significant additional debt financing
to fund the capital requirements of its business strategies, including the
proposed development of a high power DBS service and any possible migration of
some or all of the existing PRIMESTAR(R) medium power customers to such high
power service. No assurance can be given that New PRIMESTAR will be able to
obtain sufficient financial resources in order to satisfy short-term and long-
term liquidity requirements. The debt to be assumed by New PRIMESTAR in
connection with the Restructuring Transaction will include (i) the credit
facility (the "PRIMESTAR Credit Facility"), which was obtained by the
Partnership to finance advances to Tempo for payments due in respect of the
construction of the Tempo Satellites, and which is in turn supported by
letters of credit arranged for by affiliates of all but one of the Partners,
(ii) the Notes and/or the Exchange Notes and (iii) any amounts outstanding
under the Bank Credit Facility. In addition, New PRIMESTAR will be responsible
for payments due under (i) the GE-2 Agreement, which provides for the
Partnership's use of transponders on GE-2, (ii) certain specified contracts
and other obligations that will be assumed by New PRIMESTAR in connection with
the ASkyB Transaction, and (iii) various other commitments and contingent
liabilities associated with the businesses and assets that will comprise New
PRIMESTAR following consummation of the Restructuring Transaction and the
ASkyB Transaction. It is anticipated that New PRIMESTAR will also be required
to amend and/or refinance the Bank Credit Facility and the PRIMESTAR Credit
Facility to the extent they are not earlier refinanced by TSAT and/or the
Partnership. As of September 30, 1997, the Partnership's advances to Tempo to
finance construction of the Tempo Satellites aggregated $463,133,000, and the
Partnership's indebtedness under the PRIMESTAR Credit Facility aggregated
 
                                      24
<PAGE>
 
$555,000,000, including amounts borrowed to pay interest charges. The maturity
date of the PRIMESTAR Credit Facility has been extended to September 30, 1998.
Long-term financing alternatives with respect to the Tempo Satellites are
currently being evaluated. No assurance can be given that any such long-term
financing will be available on acceptable terms.
 
  The degree to which the Borrower is leveraged may adversely affect the
Borrower's ability to compete effectively against better capitalized
competitors and to withstand downturns in its business or the economy
generally, and could limit its ability to pursue business opportunities that
may be in the interests of the Borrower and its stockholders. The Borrower's
ability to repay or refinance its debt will be dependent upon the Borrower's
ability to generate substantial cash flow from operations or to obtain
additional debt or equity financing. There can be no assurance that the
Borrower will be successful in generating sufficient cash flow from operations
or in a timely manner or in raising sufficient additional debt or equity
financing to enable it to repay or refinance its debt. In addition, the
failure of the Borrower to have adequate access to capital may adversely
affect the Borrower's ability, or choice, to launch proposed products and
services in the time frames discussed herein. Further, the failure to comply
with the covenants and other provisions of the Borrower's debt instruments
could result in events of default under such instruments. Such events of
default could permit acceleration of the debt under such instruments and, in
some cases, acceleration of debt under other instruments that contain cross-
default or cross-acceleration provisions. See "--Ability to Service Debt;
Restrictive Covenants; Refinancing Risks."
 
  In the event that the Restructuring Transaction is not consummated, TSAT
believes that its cash and cash equivalents, together with borrowing
availability pursuant to the Bank Credit Facility and any funds generated by
TSAT's operating activities will be sufficient through December 31, 1998, to
fund TSAT's working capital, debt service and currently projected capital
expenditure requirements associated with its medium power satellite
distribution business. However, to the extent that the Restructuring
Transaction is not consummated and TSAT (i) funds all or any significant
portion of the cost of the Tempo Satellites, (ii) pursues a strategy with
respect to the high power segment of the digital satellite industry that
requires significant capital expenditures, (iii) completes any significant
acquisitions, (iv) enters into any other business activities that require
significant capital investments, (v) is unable (and/or the Partnership is
unable) to refinance the Tempo Satellites (to the extent not sold to a person
other than the Partnership) without a letter of credit and is unable to post
(or arrange for the posting of) such letter of credit, or is required to meet
other significant future liquidity requirements in addition to those described
above, TSAT anticipates that it would be required to obtain additional debt or
equity financing. No assurance can be given, however, that TSAT would be able
to obtain additional financing on terms acceptable to it, or at all.
 
SUBORDINATION OF THE EXCHANGE NOTES
 
  The Exchange Notes will be junior and subordinated in right of payment to
all existing and future Senior Indebtedness of the Borrower, including
borrowings under the Bank Credit Facility. By reason of such subordination, in
the event of a bankruptcy, insolvency, liquidation or other reorganization of
the Borrower, the assets of the Borrower will be available to pay obligations
on the Exchange Notes only after all Senior Indebtedness has been paid in
full, and there may not be sufficient assets remaining to pay amounts due on
all or any of the Exchange Notes then outstanding. The Borrower will not make
any payment with respect to the principal of, or interest on, the Exchange
Notes if (i) an event of default exists in the payment of principal or
interest with respect to any Senior Indebtedness or (ii) the holders of
Designated Senior Indebtedness (as defined) shall have issued a Payment
Blockage Notice (as defined). See "Description of the Exchange Notes--
Subordination of the Exchange Notes." In addition, under certain
circumstances, the payments of principal of, or interest on, the Exchange
Notes during the continuation of a default or an event of default under the
Bank Credit Facility will constitute an event of default under the Bank Credit
Facility.
 
  As of December 31, 1997, total Senior Indebtedness was $79,949,000, of which
$48,000,000 represented borrowings under the Bank Credit Facility at December
31, 1997. All borrowings under the Bank Credit Facility are guaranteed on a
senior basis by the Borrower's restricted subsidiaries (currently all of
TSAT's subsidiaries except Tempo). Additional Senior Indebtedness may be
incurred by the Borrower and guaranteed by its subsidiaries on a senior basis
from time to time, subject to certain restrictions.
 
                                      25
<PAGE>
 
  The Exchange Notes will not be secured by any of the Borrower's assets.
Under the Bank Credit Facility, the obligations of the Borrower and all its
domestic subsidiaries (except Tempo) that are at least 80% owned, directly or
indirectly, by the Borrower, on a fully diluted basis, will be secured by
substantially all the assets of the Borrower and such subsidiaries. If the
Borrower becomes insolvent or is liquidated, or if payment under the Bank
Credit Facility is accelerated, the lenders under the Bank Credit Facility
would be entitled to exercise the remedies available to a secured lender under
applicable law and pursuant to the terms of the Bank Credit Facility.
Accordingly, any claims of such lenders with respect to such assets will be
prior to any claim of the holders of the Exchange Notes with respect to such
assets. There can be no assurance that the Borrower's assets could be sold
quickly enough, or for sufficient amounts, to enable the Borrower to meet its
obligations (including its obligations with respect to the Exchange Notes and
any outstanding Notes). The Borrower anticipates that New PRIMESTAR will be
required to refinance and/or amend the Bank Credit Facility after consummation
of the Restructuring Transaction to the extent it is not earlier amended
and/or refinanced prior to such consummation, given that certain terms and
conditions thereof would be violated upon consummation of the Restructuring
Transaction. No assurance can be given that any such refinancing and/or
amendment will be completed on terms acceptable to the Borrower.
 
  The Exchange Notes will not be guaranteed by any of the Borrower's
subsidiaries. All of the Borrower's subsidiaries other than Tempo have
unconditionally guaranteed the Bank Credit Facility and, accordingly, claims
of holders of Exchange Notes will be structurally subordinated to the claims
of such subsidiaries' creditors, including the lenders under the Bank Credit
Facility and trade creditors of such subsidiaries. See "Description of the
Exchange Notes--Certain Covenants."
 
ABILITY TO SERVICE DEBT; RESTRICTIVE COVENANTS; REFINANCING RISKS
 
  TSAT has incurred substantial indebtedness, all of which will be assumed by
New PRIMESTAR in connection with the Restructuring Transaction, and it is
expected that New PRIMESTAR will incur substantial indebtedness. See "--
Substantial Leverage; Additional Indebtedness Likely." The agreements pursuant
to which the Borrower's existing indebtedness was incurred contain, and any
additional financing agreements may contain, certain restrictive covenants.
The restrictions contained in the existing financing agreements affect, and in
some cases limit, among other things, the ability of the Borrower to incur
additional indebtedness, redeem or purchase subordinated indebtedness
(including the Exchange Notes and any outstanding Notes), create certain
liens, make certain restricted payments, permit dividend and other payment
restrictions to apply to certain subsidiaries, enter into certain transactions
with affiliates and certain other related persons or consummate certain
merger, consolidation or similar transactions. In addition to the restrictive
covenants described above, such financing agreements require the Borrower to
maintain certain financial ratios and to comply with other operating
performance tests or other covenants. The failure of the Borrower to maintain
such ratios or comply with such other tests or covenants would constitute
events of default under such agreements (allowing the creditors to accelerate
the maturity of the indebtedness thereunder and may limit the availability of
funds under such agreements to amounts less than the stated maximum committed
amounts thereunder), notwithstanding the ability of the Borrower to meet its
debt service obligations. Although these covenants are subject to a number of
significant exceptions and qualifications, these restrictions may inhibit the
Borrower ability to manage its business and to react to changing market
conditions.
 
  The Borrower's ability to meet its debt service obligations will be
dependent upon the Borrower's future performance, which is subject to numerous
factors, many of which are beyond its control. See "--Risks of Satellite
Failure" and "--Uncertainty Regarding High Power Strategies." There can be no
assurance that the Borrower will generate sufficient cash flow from operating
activities to meet debt service, capital expenditure and working capital
requirements. It is anticipated that after consummation of the Restructuring
Transaction, New PRIMESTAR will be required to amend and/or refinance the Bank
Credit Facility and the PRIMESTAR Credit Facility to the extent they are not
earlier amended and/or refinanced by TSAT and/or the Partnership. The Borrower
expects that the Borrower's other outstanding indebtedness will need to be
refinanced at maturity. The Borrower's ability to refinance such indebtedness
will depend on, among other things, its financial condition at the time, the
restrictions in the instruments governing its indebtedness and other factors,
including market
 
                                      26
<PAGE>
 
conditions, beyond the control of the Borrower. In addition, in the event the
Borrower does not generate sufficient cash flow from operating activities to
meet debt service requirements, the Borrower may need to seek additional debt
or equity financing. There can be no assurance that the Borrower will be
successful in generating sufficient cash flow from operating activities or in
a timely manner or in raising sufficient additional debt or equity financing
on terms that are acceptable to the Borrower, if at all, to enable it to repay
or refinance its debt. In the absence of such financing or refinancing, the
Borrower could be forced to dispose of assets in order to cover any shortfall
in the payments due on its indebtedness and such disposition may occur under
circumstances that might not be favorable to realizing the highest price for
such assets. In addition, the failure of the Borrower to have adequate access
to capital may adversely affect the Borrower's ability, or choice, to
commercially launch proposed products and services in the time frames planned
by the Borrower. See "--Substantial Leverage; Additional Indebtedness Likely"
and "--History of Losses of TSAT and Other Restructuring Parties."
 
DEFICIENCY OF EARNINGS TO FIXED CHARGES
 
  The ratio of earnings to fixed charges of TSAT was less than 1.00 for the
nine months ended September 30, 1997, and for the years ended December 31,
1996, 1995 and 1994. Thus, earnings available for fixed charges were
inadequate to cover fixed charges for such periods. The amounts of coverage
deficiencies were $166,544,000, $185,941,000, $69,365,000 and $20,560,000 for
the nine months ended September 30, 1997 and for the years ended December 31,
1996, 1995 and 1994, respectively. TSAT has agreed to reimburse TCI UA 1,
Inc., an indirect consolidated subsidiary of TCI Communications, Inc., for any
amounts drawn under an irrevocable transferrable letter of credit, which
supports the PRIMESTAR Credit Facility. Fixed Charges relating to such
agreement of $6,489,000, $8,475,000, $9,888,000 and $3,374,000 for the nine
months ended September 30, 1997, and the years ended December 31, 1996, 1995
and 1994, respectively, are included in fixed charges.
 
REPURCHASE OF THE EXCHANGE NOTES UPON A CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, the Borrower will be obligated
to make an offer to purchase all Exchange Notes and any remaining Notes
outstanding at a purchase price in cash equal to (i) with respect to the
Senior Subordinated Notes and Senior Subordinated Exchange Notes, 101% of the
aggregate principal amount thereof, plus accrued and unpaid interest thereon,
if any, to the date of purchase and (ii) with respect to the Senior
Subordinated Discount Notes and the Senior Subordinated Discount Exchange
Notes, 101% of the Accreted Value on the date of purchase (unless the date of
purchase is on or after the earlier to occur of February 15, 2002 and the Cash
Interest Election Date, in which case such purchase price shall be equal to
101% of the aggregate principal amount at maturity thereof, plus accrued and
unpaid interest thereon, if any, to the date of purchase). See "Description of
the Exchange Notes--Offer to Purchase upon Change of Control." There can be no
assurance that the Borrower will have sufficient funds available at the time
of any Change of Control to pay for all of the Exchange Notes and the Notes
that might be tendered by holders of Exchange Notes and Notes seeking to
accept such offer to purchase. In addition, the Bank Credit Facility contains
a covenant prohibiting the Borrower from repurchasing any subordinated
indebtedness of the Borrower, including the Exchange Notes and the Notes, the
violation of which constitutes an event of default thereunder.
 
  A "change of control" will constitute an event of default under the Bank
Credit Facility, permitting the lenders thereunder to accelerate the repayment
of indebtedness thereunder, in which case the subordination provisions of the
Exchange Notes and the Notes would require the payment in full of the Bank
Credit Facility and any other Senior Indebtedness before the Borrower could
distribute cash to purchase the Exchange Notes and the Notes. See "Description
of the Exchange Notes--Subordination of the Exchange Notes."
 
  The pending Restructuring Transaction, if consummated as presently
contemplated, will not constitute a Change of Control.
 
ORIGINAL ISSUE DISCOUNT CONSEQUENCES OF SENIOR SUBORDINATED DISCOUNT NOTES AND
SENIOR SUBORDINATED DISCOUNT NOTES
 
  The Senior Subordinated Discount Notes were issued at a discount from their
principal amount at maturity. Upon exchange, holders of Senior Subordinated
Discount Notes shall receive Senior Subordinated Exchange
 
                                      27
<PAGE>
 
Notes having an aggregate principal amount at maturity equal to the aggregate
principal amount at maturity of the Senior Subordinated Discount Notes
exchanged. Although cash interest is not expected to accrue on the Senior
Subordinated Discount Notes (or the Senior Subordinated Discount Exchange
Notes exchanged therefor) prior to February 15, 2002, and there are not
expected to be any periodic payments of interest on such Notes or such
Exchange Notes prior to August 15, 2002 (unless a Cash Interest Election shall
have been made), original issue discount (the difference between the "stated
redemption price at maturity" and the "issue price," as such terms are defined
in the Internal Revenue Code of 1986, as amended to the date hereof (the
"Code"), and Treasury Regulations thereunder) ("OID") of the Senior
Subordinated Discount Exchange Notes and Senior Subordinated Discount Notes
will accrete from the issue date of such Exchange Notes and such Notes up to
February 15, 2002. Consequently, purchasers of Senior Subordinated Discount
Exchange Notes, along with the holders of Senior Subordinated Discount Notes
not tendered for Exchange Notes, generally will be required to include amounts
in gross income for United States federal income tax purposes in advance of
their receipt of the cash payments to which the income is attributable. Such
amounts in the aggregate will be equal to the difference between the "stated
redemption price at maturity" and the "issue price" (inclusive of stated
interest). See "Certain Federal Income Tax Considerations" for a more detailed
discussion of the federal income tax consequences of the purchase, ownership
and disposition of the Senior Subordinated Discount Exchange Notes.
 
  In the event a bankruptcy case is commenced by or against the Borrower under
the United States Bankruptcy Code (the "Bankruptcy Code") after the issuance
of the Senior Subordinated Discount Exchange Notes, the claim of a holder of
Senior Subordinated Discount Exchange Notes and the claim of a holder of
Senior Subordinated Discount Notes may be limited to an amount equal to the
sum of (i) the initial offering price and (ii) that portion of the OID which
is not deemed to constitute "unmatured interest" for purposes of the
Bankruptcy Code. Any OID that was not amortized as of the date of any such
bankruptcy filing would constitute "unmatured interest." To the extent that
the Bankruptcy Code differs from the Code in determining the method of
amortization of OID, any such holder may realize taxable gain or loss on
payment of such holder's claim in bankruptcy.
 
RISK OF INABILITY TO RECEIVE POSTBANKRUPTCY INTEREST
 
  Under the Bankruptcy Code, interest accruing after the date of the
commencement of bankruptcy proceedings on unsecured or undersecured debt does
not give rise to an allowable claim. Accordingly, in the event that the
Borrower becomes the subject of proceedings under the Bankruptcy Code, it is
expected that interest on the Exchange Notes and any remaining Notes
outstanding accruing after the date of commencement of bankruptcy proceedings
will not be allowable as a claim, and that no payment or distribution will be
made with respect to such postbankruptcy interest.
 
RISK OF SATELLITE FAILURE
 
  Limited Life of Satellites. All satellites have limited useful lives, which
vary as a result of their construction, the durability of their components,
the capability of their solar arrays and batteries, the amount of
stationkeeping fuel remaining once in orbit, the launch vehicle used and the
accuracy of the launch. Since March 10, 1997, the PRIMESTAR(R) service has
been transmitted from GE-2, a medium power satellite that was launched into
the 85(degrees)W.L. orbital position on January 30, 1997, and was declared
commercially operational March 6, 1997. The minimum design life of GE-2 is 15
years. There can be no assurance, however, that such satellite will achieve
its minimum design life, and the contract with GE Americom does not guarantee
the minimum useful life of GE-2. The Borrower could be adversely affected if
GE-2 or any other satellite used in connection with its business failed prior
to its minimum design life.
 
  The minimum design life of each of the Tempo Satellites is 12 years. There
can be no assurance, however, that either Tempo Satellite will achieve its
minimum design life, and the contract with Loral does not guarantee the
minimum useful life of the Tempo Satellites.
 
  Risks of Satellite Defect, Loss or Reduced Performance. Satellites are
subject to significant risks, including: manufacturing defects affecting the
satellite or its components; launch failure resulting in damage to,
 
                                      28
<PAGE>
 
or destruction of, the satellite or incorrect orbital placement; and damage in
orbit caused by asteroids, space debris or electrostatic storms. Such factors
may prevent or limit commercial operation or reduce the satellite's useful
life. Neither TSAT nor the Partnership is entitled to the benefit of any
insurance relating to the operation of GE-2.
 
  Tempo DBS-1 was outfitted with an antenna suitable for operation at the
119(degrees) W.L. orbital location and was launched into geosynchronous orbit
on March 8, 1997, on an Atlas rocket from Cape Canaveral by International
Launch Services on behalf of Lockheed Martin Corporation. Tempo DBS-1 is
currently undergoing extended in-orbit testing under the Satellite
Construction Agreement. Since the launch of Tempo DBS-1, Loral has notified
Tempo of at least five separate occurrences of power reductions on Tempo DBS-
1. No assurance can be given that further power reductions will not occur in
the future. The Borrower does not currently know the extent of such power
reductions, and cannot confirm the precise causes thereof; however, such
reductions could eventually affect the proposed operation of Tempo DBS-1,
either alone or together with other events that may arise during the expected
life of the satellite. The Borrower believes that Tempo DBS-1 may not fully
comply with specifications, but has not yet determined the extent of any such
non-compliance. Tempo and Loral are currently engaged in discussions regarding
this matter, including the timing, extent and methodology of any further tests
to be conducted and the terms of any monetary settlement with respect to the
satellite to which Tempo may be entitled under the Satellite Construction
Agreement. A defect or damage affecting Tempo DBS-1 could cause a substantial
monetary loss to the Borrower.
 
  The Borrower is entitled to the benefit of certain limited warranties and
insurance coverage relating to the Tempo Satellites pursuant to the Satellite
Construction Agreement with Loral. However, such warranties and insurance
coverage might not be sufficient to compensate it for all of its losses in the
event of a partial or total satellite failure or casualty, even if such
failure or casualty were a covered loss.
 
ABILITY TO MANAGE GROWTH; SUBSCRIBER CHURN
 
  TSAT's business and the businesses of the Partnership and the other
Distributors have grown rapidly since 1994, when the Partnership completed its
adoption of digital technology. The Borrower believes that such rapid growth
has been a factor in the increases it has experienced in both subscriber churn
and bad-debt write-offs. The ability of the Borrower to continue its expansion
and increase its customer base while maintaining its price structure, reducing
its churn rate and managing costs will depend upon, among other things, the
Borrower's ability to manage its growth effectively. To manage growth
effectively, the Borrower must continue to develop its internal and external
sales force, installation capability, customer service team and information
systems, maintain its relationships with third party vendors and implement
efficient procedures to mitigate subscriber credit risk. The Borrower will
also need to continue to grow, train and manage its employee base, and its
management will be required to assume greater levels of responsibility. If the
Borrower is unable to manage its growth effectively, the Borrower's business
and results of operations could be materially adversely effected.
 
  During the nine months ended September 30, 1997 and 1996, and the years
ended December 31, 1996, 1995 and 1994, (i) the Borrower's annualized
subscriber churn rate (which represents the annualized number of subscriber
terminations divided by the weighted average number of subscribers during the
period) was 32.2%, 38.9%, 38.5%, 24.7% and 16.1%, respectively, and (ii) the
average subscriber life implied by such subscriber churn rate was 3.1 years,
2.6 years, 2.6 years, 4.1 years and 6.2 years, respectively. The Borrower's
experienced a higher rate of subscriber churn in 1996, as compared to the
first nine months of 1997 and prior periods. The Borrower believes that the
higher 1996 churn rate is primarily attributable to the fact that subscribers
were allowed to initiate service with no credit approval during the fourth
quarter of 1995 and the first six months of 1996. Although no assurance can be
given, the Borrower expects that churn rates for future periods will be lower
than the levels experienced in 1996. If the Borrower's churn rates were to
return to, or increase from, such 1996 levels, the Borrower believes that its
financial condition and results of operations would be adversely affected.
 
  TSAT is currently unable to determine New PRIMESTAR'S annualized subscriber
churn rate on a pro forma basis for past periods. If, following the closing of
the Restructuring Transaction, New PRIMESTAR's
 
                                      29
<PAGE>
 
churn rates exceed TSAT's churn rate for the nine months ended September 30,
1997, or fail to improve from such levels in subsequent periods, TSAT believes
that the financial condition and results of operations of New PRIMESTAR would
be adversely affected.
 
UNCERTAINTIES OF OPERATIONS FOLLOWING THE RESTRUCTURING TRANSACTION
 
  The success of the Restructuring Transaction and the related transactions
will depend in part on the ability of New PRIMESTAR to integrate effectively
the businesses of TSAT and the Partnership and the PRIMESTAR(R) distribution
businesses of the other Distributors, each of which currently operates
separately. There can be no assurance that successful integration of such
businesses or that the benefits expected to result from such integration will
be realized. The process of integrating such businesses may also require a
disproportionate amount of time and attention of New PRIMESTAR's management
and financial and other resources of New PRIMESTAR. In addition, the
integration of the businesses of TSAT and the Partnership and the PRIMESTAR(R)
distribution businesses of the other Distributors may be made more difficult
initially by the necessity of coordinating geographically separated
organizations and integrating personnel with disparate business backgrounds
and corporate cultures. If New PRIMESTAR is not successful in integrating the
strategies and operations of such businesses or if such integrated operations
fail to achieve consumer acceptance, the combined business could be adversely
affected. Further, any delays or unexpected costs that arise in connection
with such integration could have a material adverse effect on the business,
results of operations or financial condition of New PRIMESTAR, as well as the
market value of New PRIMESTAR securities.
 
COMPETITIVE NATURE OF INDUSTRY
 
  The business of providing video programming to consumers is highly
competitive. The Borrower faces competition from numerous other companies
offering video, audio and data products and services. The existing and
potential competitors of the Borrower comprise a broad range of companies
engaged in communications and entertainment, including other digital satellite
programming distributors, cable operators, wireless cable operators,
television networks and home video products companies, as well as companies
developing new technologies and other purveyors of news, information and
entertainment. The Borrower competes, among others, with companies offering
programming through various other satellite broadcasting systems, including
DirecTv, Inc. ("DirecTv"), a unit of Hughes Electronics Corp., which is a
division of the General Motors Corporation, United States Satellite
Broadcasting Corporation ("USSB") and EchoStar, which transmit from high power
satellites and generally use smaller dishes to receive their signals. There
can be no assurance that the Borrower will be able to compete successfully
against current and prospective providers of digital satellite programming
services, some of which will have access to greater resources and/or have
secured the rights to broadcast from a greater number of satellite transponder
frequencies.
 
  Many of the Borrower's cable competitors have greater financial, marketing
and programming resources than the Borrower. Cable operators generally have
large installed customer bases, and many cable operators have significant
investments in, and access to, programming. According to industry sources,
cable television service is currently available to more than 95% of the
approximately 97 million U.S. television households, and approximately 67% of
total U.S. television households currently subscribe to cable. In order to
substantially increase its subscriber base, the Borrower will be required to
attract customers who currently subscribe to cable and to expand commercial
accounts, including hotels, motels, bars and restaurants as well as MDUs.
There can be no assurance that the Borrower will be able to substantially
increase its subscriber base or successfully attract customers in competition
with cable operators.
 
UNCERTAINTY REGARDING HIGH POWER STRATEGIES
 
  TSAT currently intends to operate Tempo DBS-1 as a platform to provide high
power digital video and audio programming services to residential customers,
MDUs, commercial customers and resellers. If the TSAT Merger or the Tempo Sale
is consummated, such high power DBS services will be provided by New
PRIMESTAR. Otherwise, TSAT expects that such services will be provided through
the Partnership, which has exercised its option under the Tempo Option
Agreement to purchase or lease 100% of the capacity of Tempo
 
                                      30
<PAGE>
 
DBS-1. Following consummation of the Restructuring Transaction, the
Partnership will be an indirect wholly owned subsidiary of New PRIMESTAR.
 
  In addition to the possibility of satellite impairment or failure as
described above under the heading "--Risk of Satellite Failure--Risks of
Satellite Defect, Loss or Reduced Performance," there are numerous
uncertainties regarding the high power DBS business proposed to be operated by
the Borrower:
 
    (i) The proposed high power DBS business is currently in the development
  stage. Programming content, pricing and other important decisions have not
  been finalized. There can be no assurance that desired programming content
  will be available on favorable terms.
 
    (ii) The FCC Permit authorizes the use of only 11 transponders on Tempo
  DBS-1, as compared to the 32 transponders operated in the aggregate by
  DirecTv and USSB on DirecTv's full CONUS DBS satellite and the 21
  transponders operated by EchoStar on its full CONUS DBS satellite. Although
  Tempo intends to utilize advanced digital compression technologies,
  including statistical multiplexing, to provide up to 100 video and 20 audio
  programming channels over such 11 transponders, there can be no assurance
  that the relatively limited capacity of Tempo DBS-1 will not have an
  adverse effect on the Borrower's proposed high power DBS business.
 
    (iii) If the ASkyB Transaction is consummated, the Partnership or New
  PRIMESTAR will use the 28 transponders currently authorized to MCI in the
  110(degrees) W.L. orbital location to provide high power DBS services to
  residential customers, commercial customers and MDUs. It can be expected
  that consummation of the ASkyB Transaction will have a material impact on
  the Borrower's strategy relating to the Tempo Satellites and FCC Permit,
  although the full nature of such impact cannot presently be determined. The
  ASkyB Transaction is subject to various regulatory approvals, and there can
  be no assurance that such approvals will be obtained, or if obtained, that
  such approvals will not be conditioned upon modifications to the high power
  strategies of the Partnership and/or the Borrower, as currently proposed.
  The ASkyB Agreement requires the Partnership to cause the divestiture of
  all rights of the Partnership and any of the Partners under Tempo's FCC
  Permit with respect to the 11 transponder channels at 119(degrees) W.L.,
  including divestiture of the Partnership's right to purchase or lease 100%
  of the capacity thereunder pursuant to the Tempo Option Agreement, if
  required as a condition to regulatory approval of the ASkyB Transaction.
 
  No assurance can be given as to the effect that the implementation of any
high power strategy will have on the Borrower's existing medium power customer
base.
 
  No assurance can be given that the Borrower will not significantly change
the direction of its high power strategy or that any high power strategy will
be successful.
 
  In light of the pendency of the Restructuring Transaction, the TSAT Merger,
the Tempo Sale and the ASkyB Transaction, the Borrower and the Partnership are
evaluating alternative future plans with respect to Tempo DBS-2, including its
use or disposition. Tempo DBS-2 presently serves as a ground spare for Tempo
DBS-1.
 
RISKS OF ADVERSE GOVERNMENT REGULATIONS AND ADJUDICATIONS
 
  General. The construction and launch of DBS satellites and the operation of
DBS systems are subject to substantial regulation by the FCC. FCC rules are
subject to change in response to industry developments, new technology and
political considerations. The Borrower's business and business prospects could
be adversely affected by the adoption of new laws, policies, and regulations.
There can be no assurance that the Borrower will succeed in obtaining all
requisite regulatory approvals for its operations without the imposition of
restrictions on, or adverse consequences to, the Borrower. There also can be
no assurance that material adverse changes in regulations affecting the
digital satellite television industry or the Borrower will not occur in the
future. See "--Potential Interference with Satellite Signal."
 
  FCC Permit. Tempo holds the FCC Permit, which authorizes construction of a
DBS system with 11 frequency channels at 119(degrees) W.L. that view the
entire continental U.S. and 11 frequency channels at 166(degrees) W.L.
 
                                      31
<PAGE>
 
that view only the western half of the continental U.S. and Alaska and Hawaii.
The FCC's DBS construction permits are conditioned on the satisfaction of
ongoing construction and related obligations. Under the FCC Permit, the time
by which the Tempo Satellites must be operational expires in May 1998. The
Borrower believes that it has complied with the obligations for Tempo DBS-1 to
become operational by that date, but there can be no assurance that the FCC
would agree that such satellite is operational, and if an application for
extension of the FCC Permit were required, there can be no assurance that such
an extension would be granted by the FCC. See "--Risk of Satellite Failure."
 
  At present, Tempo must continue to demonstrate that it is exercising due
diligence in progressing toward the completion of its DBS system at
166(degrees) W.L. and has in place the Satellite Construction Agreement with
Loral to fulfill this due diligence requirement. There can be no assurance
that Tempo will be able to comply with the FCC's due diligence obligations for
166(degrees) W.L. or that the FCC will determine that Tempo has complied with
such due diligence obligations. If Tempo is unable to meet the terms of the
FCC Permit, it would be required to apply to the FCC for an extension of time
to complete its DBS system at 166(degrees) W.L. Tempo cannot be certain that
an extension would be granted.
 
  Tempo also may be required to file an application for a license to operate
its satellites in orbit. Tempo expects that the FCC would approve any such
request but cannot assure the ultimate outcome. FCC licenses must be renewed
at the end of each license term. Generally, FCC licenses are renewed in the
ordinary course, absent misconduct by the licensee.
 
  On July 18, 1997, TSAT and the Partnership filed an application with the FCC
for consent to the transfer of control of Tempo, as the holder of the FCC
Permit, to New PRIMESTAR (the "Transfer Application"). The Transfer
Application must be approved by the FCC before consummation of the TSAT Merger
or any Tempo Sale. Petitions to deny and comments were filed against the
Transfer Application. The comments and petitions urge the FCC to either deny
the Partnership and those Restructuring Parties affiliated with large cable
operators the opportunity to provide high power DBS service or to condition
any such provision. TSAT and the Partnership filed a joint opposition to these
petitions and comments. Before approving the Transfer Application, the FCC
must review the petitions filed and responsive pleadings and find that there
are no material issues of fact that should prevent approval of the TSAT Merger
or any Tempo Sale and that approval would serve the public interest. There can
be no assurance that the FCC's review of the Transfer Application and the
petitions will be favorable, or that the FCC will not impose conditions
unacceptable to TSAT, the Partnership, or the other Restructuring Parties in
connection with its review. Approval of the Transfer Application is a
prerequisite of the TSAT Merger (so long as TSAT controls Tempo) or any Tempo
Sale, but is not required to complete the Restructuring Transaction.
 
  In addition, on August 15, 1997, the Partnership and MCI filed an
application with the FCC for consent to the assignment to New PRIMESTAR of the
high power DBS authorizations and certain other assets owned by MCI (the
"Assignment Application"). The Assignment Application must be approved by the
FCC before the consummation of the ASkyB Transaction. The FCC placed the
Assignment Application on Public Notice for comments. While MCI has a
contractual obligation to maintain its due diligence at the FCC with respect
to its DBS authorizations that are subject to the Assignment Application,
there can be no assurance that MCI will do so.
 
  Numerous parties have filed comments and petitions to deny with regard to
the Assignment Application. The petitions and comments urge the FCC to either
deny the Assignment Application or to condition its approval. The issues
raised in these petitions and comments include the following: (1) opposition
to the Partnership or New PRIMESTAR holding the 110(degrees) W.L.
authorization; (2) opposition to the Partnership or New PRIMESTAR
simultaneously holding authorizations for both the 110(degrees) W.L. orbital
position (28 transponders) and the 119(degrees) W.L. orbital position (11
transponders), which together represent about 40% of the total transponder
capacity in the three orbital positions allocated to the U.S. for DBS service
that provide full CONUS visibility; (3) requests for extension of the FCC's
rules governing access to satellite delivered programming to News Corp. and
expansion of those rules to programming not delivered by satellite (such as
broadcast television stations), and
 
                                      32
<PAGE>
 
(4) issues relating to the possible applicability of the foreign ownership
restrictions of Section 310(b) of the Communications Act of 1934, as amended
(together with the rules and regulations promulgated thereunder, the
"Communications Act"). There can be no assurance that the FCC's review of
these and other documents or the Assignment Application will be favorable, or
that the FCC will not impose conditions unacceptable to New PRIMESTAR, MCI,
ASkyB or News Corp. in connection with its review.
 
  MCI's authorization from the FCC to construct, launch and operate satellites
in the DBS service at 110(degrees) W.L. providing 28 transponder channels of
service (the "110 Slot"), one of MCI's DBS authorizations at issue in the
Assignment Application, was purchased by MCI at an FCC auction in January
1996. The other DBS authorization is a waiver of Section 319(d) of the
Communications Act, granting MCI authority to construct a DBS satellite
without an FCC construction permit at its own risk. Before the auction of the
110 Slot, the FCC imposed a one-time auction rule which required the entity
who bought the 110 Slot to divest any voting interest of five percent or
greater held in DBS permittees or licensees that hold FCC authorizations for
the two other DBS slots that view the entire continental U.S. (the
"Divestiture Requirement"). These two slots include 101(degrees) W.L. and
119(degrees) W.L. While the Divestiture Requirement was promulgated as a one-
time rule, the FCC may decide to impose this rule as a condition to approving
the Assignment Application and to require New PRIMESTAR to divest its interest
in 119(degrees) W.L.
 
  Should the FCC determine that foreign ownership restrictions apply to
subscription DBS service providers, then, as a condition to the consummation
of the ASkyB Transaction, New PRIMESTAR would have to seek a waiver of such
restrictions. There can be no assurance that the FCC would grant such a
waiver.
 
  SHVA. The Satellite Home Viewer Act of 1994 ("SHVA") prohibits the
retransmission by a satellite carrier of a television broadcast signal of a
network television station to households that receive a Grade B intensity
over-the-air signal of a television broadcast station affiliated with such
network and to households that receive (or within the past 90 days had
received) through a cable system the signal of a television station affiliated
with such network. In complying with the SHVA, the Partnership is required to
discontinue network service to certain of its subscribers who are able to
receive network services over the air. The Partnership has received numerous
challenges to its network subscribers from certain network affiliates and in
some instances has discontinued network service to certain subscribers. The
networks and their affiliates have commenced infringement actions against
certain other satellite carriers for violation of the network service
restrictions. However, while the networks and affiliates have from time to
time threatened litigation, none of the networks or affiliates has yet
asserted any claim for damages under applicable law against the Partnership or
any of the other parties to the Roll-up Plan. Negotiations are continuing
among representatives of the Partnership, the National Association of
Broadcasters, certain network-affiliated television stations, and their
respective affiliate associations, regarding a proposed Settlement and
Compliance Agreement, which agreement is expected to provide for pre-screening
techniques for customers based on zip codes and maps to ensure compliance with
SHVA procedures, the timing for disconnecting any existing non-compliant
network subscribers, and provisions for mutual release for any past or future
liability. Although a final agreement with respect to such matters has not yet
been executed, the Partnership currently expects to enter into such an
agreement during the first quarter of 1998. However, if an agreement is not
reached, it is likely that litigation will be initiated against the
Partnership. The SHVA provides for remedies which can include actual damages,
injunctions, and statutory damages. Statutory damages per individual claim are
limited to $5.00 per subscriber, per month, and statutory damages for a
pattern or practice of violations are limited to $250,000 in a six month
period. At present, the Partnership is unable to determine the basis upon
which any damages might be calculated or what their amount might be.
Therefore, it is not possible to assess the impact, if any, of such unasserted
claims on the Partnership's results of operations or cash flow. Management is
also currently unable to determine the extent to which the restriction on the
delivery of network service to subscribers, as contemplated by the proposed
Settlement and Compliance Agreement, would have on the marketing of its
services generally.
 
  Increase in Compulsory License Fees. A Copyright Arbitration Royalty Panel
("CARP"), convened pursuant to the terms of the SHVA, recommended to the
Librarian of Congress that the royalty fees paid by satellite carriers for the
distribution of superstations and network affiliates directly to homes should
be increased
 
                                      33
<PAGE>
 
to a level commensurate with fair market value, which is far in excess of the
rate currently paid by cable operators. The Librarian of Congress accepted
CARP's recommendation to increase the royalty fees and determined that the new
fees should become effective as of January 1, 1998. The Satellite Broadcasting
and Communications Association ("SBCA"), representing the satellite carriers,
filed a petition with the Librarian of Congress requesting a stay of the
effectiveness of the decision, pending judicial review or congressional
action. The Librarian of Congress denied the petition, and as of January 1,
1998, the rate increase went into effect. The SBCA also filed a petition
seeking review of the rate increase with the U.S. Court of Appeals for the
District of Columbia. In addition, the satellite carriers have requested
Congress to override the rate adjustment by legislation. A bill has been
introduced in the Senate (S. 1422) which would delay an increase in the
royalty fees until January 1, 1999 and would require the FCC to report to
Congress within 180 days of enactment of the legislation on the effect of the
increase of the royalty fees on the satellite carriers' abilities to compete
in the market for delivery of multichannel video programming. A bill also has
been introduced in the House of Representatives (H.R. 2291) which is similar
to the Senate bill and requires a stay of the royalty increase until the FCC
reviews the effects on the market and reports to Congress; however, the stay
would be in effect no later than 210 days after enactment. No assurance can be
given that the satellite carriers will be able to obtain relief from the U.S.
Court of Appeals or Congress. Should the decision of the Librarian of Congress
stand, Tempo or New PRIMESTAR (and all other direct satellite service
providers) may be competitively disadvantaged vis-a-vis cable operators.
 
  State Taxes. In addition to being subject to FCC regulation, operators of
DBS systems in the U.S. may be affected by imposition of state sales taxes on
satellite-delivered programming. According to the SBCA, several states,
including Maryland, Missouri, North Dakota, New York and Washington have
either adopted or proposed such taxes. Other states are in various stages of
considering proposals that would tax providers of satellite-delivered
programming and other communications providers. The provision of state imposed
sales taxes could have adverse consequences to the Borrower's business.
 
  There can be no assurance that additional government regulations affecting
DBS permittees and licensees will not occur in the future.
 
  Issues Affecting Competitors. On July 18, 1997, EchoStar and DirectSat
Corporation, a subsidiary of EchoStar ("DirectSat"), filed a consolidated
application for special temporary authority ("STA Application") to provide DBS
service over the 11 channels at 119(degrees) W.L. currently held by Tempo.
EchoStar and DirectSat hold the authorization to use the remaining 21 channels
at the 119(degrees) W.L. orbital location and currently are offering service
from that location as the DISH Network.
 
  EchoStar temporarily used certain of Tempo's channels prior to Tempo's March
1997 satellite launch. However, in June 1996, the FCC denied both EchoStar's
and DirectSat's requests to extend the STA Application for use of the Tempo
channels. The FCC was concerned that when Tempo eventually launched its
satellite and commenced its own service, the resultant reduction in service by
EchoStar and DirectSat would confuse customers. While EchoStar and DirectSat
claimed that customers would not miss their proposed pay-per-view services to
be offered over Tempo's channels, the FCC disagreed and denied their requests.
 
  In their STA Application, EchoStar and DirectSat argued that Tempo was
either wasting its allocated channels by not using them or warehousing the
channels for use by another party. Furthermore, EchoStar and DirectSat stated
that New PRIMESTAR, which is set to acquire Tempo or Tempo's assets pursuant
to the TSAT Merger or any Tempo Sale, indicated its willingness to return
Tempo's 11 channels at 119(degrees) W.L., if required, as a condition for FCC
approval of the Assignment Application. Tempo has filed a petition to deny the
STA Application, but the outcome of the proceeding cannot be guaranteed.
 
  DirecTv recently filed an application with the FCC to expand its existing
satellite system, currently located at 101(degrees) W.L. In its June 5, 1997
application, DirecTv requested orbital slots located at 96.5(degrees) W.L. and
105.5(degrees) W.L. To implement this expansion, DirecTv must secure
additional frequencies in order to transmit and receive signals at these
additional orbital locations. Thus, in a related petition for rulemaking (also
filed June 5, 1997),
 
                                      34
<PAGE>
 
DirecTv requested that the FCC reallocate certain frequencies for DBS use.
DirecTv also requested that the standard 9 spacing policy be abandoned in
favor of a 4.5 spacing policy. The public was invited to comment on DirecTv's
petition, and comments were filed by interested parties on July 31, 1997.
Commenters generally complained that interference with other satellite
transmissions might result from DirecTv's expansion plan. The FCC to date has
not issued a Notice of Proposed Rulemaking in this matter, which is a
prerequisite to the frequency reallocation requested by DirecTv. In addition,
even if the reallocation is eventually granted, there can be no guarantee that
DirecTv will be assigned the frequency authorizations and orbital locations it
has requested. These authorizations would be available to competing applicants
as well.
 
  Should the FCC adopt a 4.5 spacing policy for DBS providers, it is possible
that the FCC would grant authorizations for satellites at locations adjacent
to Tempo's and the Partnership's satellites which may cause interference.
Moreover, if the FCC adopts a 4.5 spacing policy, it is possible that a
competitor would control more full CONUS DBS transmission capacity than New
PRIMESTAR and therefore, potentially would be able to offer more services than
New PRIMESTAR. In any event, it is uncertain whether DirecTv's requests will
be granted.
 
POTENTIAL INTERFERENCE WITH SATELLITE SIGNAL
 
  The International Bureau of the FCC (the "International Bureau") has granted
EchoStar Satellite Corporation, a subsidiary of EchoStar Communications
Corporation (together with its consolidated subsidiaries, "EchoStar") a
conditional authorization to construct, launch and operate a Ku-band domestic
fixed satellite into the orbital position at 83(degrees) W.L., immediately
adjacent to that occupied by GE-2, the medium power satellite currently used
to provide the PRIMESTAR(R) service. Contrary to previous FCC policy, which
would have permitted operation of a satellite at the 83(degrees) W.L. orbital
position at a power level of only 60-90 watts (subject to coordination
requirements), EchoStar has been authorized to operate at a power level of 130
watts. If EchoStar were to launch its high power satellite authorized to
83(degrees) W.L. and commence operations at that location at a power level of
130 watts, it would likely cause harmful interference to the reception of the
PRIMESTAR(R) signal from GE-2 by subscribers to the PRIMESTAR(R) medium power
service.
 
  GE Americom and the Partnership have each requested reconsideration of the
International Bureau's authorization for EchoStar to operate at 83(degrees)
W.L. These requests, which were opposed by EchoStar and others, are currently
pending at the International Bureau. There can be no assurance that the
International Bureau will change slot assignments, or power levels, in a
fashion that eliminates the potential for harmful interference. Accordingly,
the ultimate outcome of this matter cannot presently be predicted.
 
  GE Americom and the Partnership have attempted to resolve potential
coordination problems directly with EchoStar. However, it is uncertain whether
any agreement in respect of such coordination between the Partnership and
EchoStar will be reached, or that even if such agreement is reached, that
coordination will resolve such interference.
 
POTENTIAL CONFLICTS OF INTEREST
 
  Following consummation of the Restructuring Transaction, TSAT will own
approximately 36% of the shares of New PRIMESTAR Common Stock outstanding (and
approximately 37% of the total voting power of the shares of New PRIMESTAR
Common Stock outstanding), and TWE and Newhouse (collectively), Comcast,
MediaOne, Cox and GE Americom will own approximately 31%, 10%, 9%, 9% and 5%,
respectively, of the shares of New PRIMESTAR Common Stock outstanding and
approximately 32%, 10%, 10%, 9% and 2%, respectively, of the total voting
power of the shares of New PRIMESTAR Common Stock outstanding, in each case
subject to adjustments based on closing subscriber counts and other factors.
Following consummation of the TSAT Merger, John C. Malone, the Chairman of the
Board and a director of TCI (and also Chairman of the Board and a director of
TSAT) will own approximately 2.0% of the shares of New PRIMESTAR Common Stock
outstanding and approximately 8.8%, of the total voting power of the shares of
New PRIMESTAR Common Stock outstanding at the Closing of the Restructuring
Transaction.

<PAGE>
 
  Affiliates of each of the Class C Stockholders and TCI and GE Americom,
individually and in joint ventures with each other and others, have
substantial other interests in the communications and entertainment
industries, some of which may compete with the business of, or provide
programming to, New PRIMESTAR. All of the Class C Stockholders and TCI,
through their respective subsidiaries and affiliates, own or have controlling
interests in cable systems throughout the United States, and because New
PRIMESTAR will be competing with such cable systems in the provision of multi-
channel video programming services, there is the potential for conflicts of
interest. The restated certificate of incorporation of New PRIMESTAR (the "New
PRIMESTAR Charter") provides for two independent directors, and Section 144 of
the DGCL, in general, provides that no related party transaction is void or
voidable solely for this reason, if: (i) the material facts as to the related
party transaction are disclosed or are known to the board of directors or the
committee which authorizes the transaction, and the board or committee in good
faith authorizes the transaction by the affirmative votes of a majority of the
disinterested directors, even though the disinterested directors be less than
a quorum; or (ii) the material facts as to the related party transaction are
disclosed or are known to the stockholders entitled to vote thereon, and the
transaction is specifically approved in good faith by vote of the
stockholders; or (iii) the related party transaction is fair as to the
corporation as of the time it is authorized, approved or ratified, by the
board of directors, a committee or the stockholders.
 
  Pursuant to the Restructuring Agreement, at the Closing, New PRIMESTAR will
enter into a Transition Period Agency Agreement with each Class C Stockholder
(or their respective affiliates), pursuant to which each such party will be
designated as a servicing agent in assigned non-exclusive territories with
respect to New PRIMESTAR's medium power PRIMESTAR(R) subscribers, for a period
of up to six months following the Closing. In addition, each Class C
Stockholder and TCI (or their respective affiliates) will have the right to
enter into an HP Agency Agreement with New PRIMESTAR, pursuant to which such
party will act as a non-exclusive retail sales and servicing agent of any
stand-alone retail high power PRIMESTAR(R) programming service. Pursuant to
the Restructuring Agreement, each Class C Stockholder and TCI (or their
respective affiliates) will also have a right to enter into a Sales Agency
Agreement, pursuant to which such party will act as a non-exclusive retail
sales agent of (i) the PRIMESTAR(R) medium power programming service, or (ii)
at any time that such party is not a party to an HP Agency Agreement, any
stand-alone retail high power PRIMESTAR(R) programming service. Such
agreements could give rise to potential conflicts of interest since in those
territories served by cable television, New PRIMESTAR will be competing for
subscribers with the cable systems owned and operated by the Class C
Stockholders and TCI, and the respective ownership interests of the Class C
Stockholders and TCI in the applicable cable systems may be greater than their
respective ownership interests in New PRIMESTAR. In order to offset this
potential for conflicts of interest, the HP Agency Agreements and the Sales
Agency Agreements will contain performance standards designed to ensure that
New PRIMESTAR's customers receive appropriate service from the applicable
Class C Stockholder or TCI with respect to installation, maintenance and other
service functions. In the event a Class C Stockholder or TCI fails materially
to satisfy the service performance standards, such party may lose its right to
provide service, but will not lose its right to act as a sales agent or to
receive the fees associated with performance of its sales agent obligations.
 
RISKS ASSOCIATED WITH THE ASKYB TRANSACTION
 
  Increased Financial Obligations. Consummation of the ASkyB Transaction will
impose additional financial obligations on New PRIMESTAR. The consideration to
be paid by New PRIMESTAR in connection with the ASkyB Transaction will
include, subject to closing adjustments, $600 million liquidation value of New
PRIMESTAR Convertible Preferred Stock and $516 million principal amount of New
PRIMESTAR Convertible Subordinated Notes. New PRIMESTAR will also assume
certain obligations under certain specified contracts and other arrangements
binding upon ASkyB, News Corp. and/or MCI, which will require New PRIMESTAR to
make payments, subject to the terms and conditions of such contracts and
arrangements. At September 30, 1997, the remaining commitments under such
obligations to be assumed aggregated approximately $187 million. Consummation
of the ASkyB Transaction will make New PRIMESTAR's future operations more
heavily dependent than they otherwise would be on the success of the proposed
high power DBS business, which is subject to numerous uncertainties. See "--
Uncertainty Regarding High Power Strategies." New PRIMESTAR
 
                                      36
<PAGE>
 
will incur additional costs if it converts all or some of its existing medium
power customers to the high power satellite service expected to be provided
with the assets acquired through the ASkyB Transaction.
 
  New PRIMESTAR's ability to meet the dividend payment and debt service
obligations it will incur as a result of the ASkyB Transaction, to fulfill the
contractual obligations it will assume and to fund the costs associated with
operating the proposed high power DBS business will depend upon New
PRIMESTAR's future performance, particularly the performance of the proposed
high power DBS business, which is subject to numerous factors, many of which
are beyond New PRIMESTAR's control. See "--Risks of Satellite Failure" and "--
Uncertainty Regarding High Power Strategies." There can be no assurance that
the high power DBS business will be successful or that New PRIMESTAR will
generate sufficient cash flow from operating activities to meet these
obligations. If New PRIMESTAR does not generate sufficient cash flow from
operating activities to meet these obligations New PRIMESTAR may need to seek
additional debt or equity financing, which may not be available on terms
acceptable to New PRIMESTAR. See "--Ability to Service Debt; Restrictive
Covenants; Refinancing Risks," "--Substantial Leverage; Additional
Indebtedness Likely" and "--History of Losses of TSAT and Other Restructuring
Parties."
 
  Failure To Consummate the ASkyB Transaction. The ASkyB Transaction is
subject to regulatory and other conditions. If the ASkyB Transaction is not
consummated, then New PRIMESTAR may not be able to secure access to the
capacity of the 110(degrees) W.L. orbital slot on terms favorable to New
PRIMESTAR or on any terms. Although New PRIMESTAR intends in such event to
pursue the proposed high power DBS business using the transponder capacity of
Tempo DBS-1, failure of New PRIMESTAR to secure the availability of a full
CONUS DBS slot with greater capacity could have an adverse effect on its
proposed high power DBS business. See "--Uncertainty Regarding High Power
Strategies."
 
  EchoStar-News Corp. Litigation. In May 1997, EchoStar filed suit against
News Corp. with respect to their previously announced and then aborted
business combination. EchoStar seeks specific performance and damages against
News Corp., including lost profits alleged by EchoStar to exceed $10 billion
over a ten-year period. In June 1997, News Corp. filed an answer and
counterclaims against EchoStar seeking unspecified damages. News Corp.'s
answer denies all material allegations in EchoStar's amended complaint and
asserts numerous defenses, including bad faith, misconduct and failure to
disclose material information on the part of EchoStar. The parties are now in
discovery. The case has been set for trial commencing June 15, 1998, but that
date may be postponed.
 
  None of TSAT, the Partnership, New PRIMESTAR or any of the other parties to
the Roll-up Plan have been named as defendants in the EchoStar-News Corp.
litigation. However, EchoStar has from time to time threatened to name some or
all of such parties as defendants in such action. Moreover, if EchoStar is
awarded specific performance, News Corp. may be prevented from consummating
the ASkyB Transaction.
 
  In connection with the ASkyB Transaction, News Corp., TSAT, the Partnership,
Time Warner, Comcast, Cox, MediaOne, Newhouse and GE Americom entered into the
ASkyB Indemnification Agreement, which agreement provides for News Corp. to
indemnify the PRIMESTAR Indemnitees (as defined therein) against, and hold
them harmless from, losses, liabilities, claims, damages, costs and expenses
relating to the foregoing claims by EchoStar and/or certain related matters.
 
DEPENDENCE ON THIRD PARTY PROGRAMMERS
 
  The Borrower will be dependent on third parties to provide The Borrower with
programming. The Partnership's existing programming agreements, of which
approximately 8% expire in 1998, 43% expire in 1999, 24% expire in 2000 and
25% expire at various times between 2001 and 2008, contain various renewal and
cancellation provisions. There can be no assurance that any of these
agreements will be renewed or will not be canceled prior to expiration of
their original term. In the event that any such agreements are not renewed or
are canceled, there can be no assurance that New PRIMESTAR would be able to
obtain or develop substitute programming, or that such substitute programming
would be comparable in quality or cost to the Partnership's
 
                                      37
<PAGE>
 
existing programming. The Partnership's competitors currently offer
substantially the same programming as the Partnership. The ability of New
PRIMESTAR to compete successfully will depend on New PRIMESTAR's ability to
continue to obtain desirable programming and attractively package it to its
customers at competitive prices.
 
RISK OF SIGNAL PIRACY
 
  In common with all providers of subscription television programming, the
Borrower faces the risk that the PRIMESTAR(R) programming signal will be
obtained by unauthorized users. If signal piracy became widespread, the
Borrower's revenue and cash flow from operations could be adversely affected,
and New PRIMESTAR's ability to contract for video and audio services provided
by programmers could be adversely affected. Historically, signal piracy in the
C-band, cable television and European digital satellite industries has been
widely reported and, more recently, published reports indicate that the
DirecTv and USSB encryption systems have been compromised. While the Borrower
management believes that the encryption method utilized by the Partnership,
which was developed by an affiliate of General Instrument Corporation ("GI"),
has been effective in minimizing signal piracy, and there have been no
published reports of breaches in PRIMESTAR(R) security, there can be no
assurance that changes in technology will not render less effective the anti-
piracy efforts associated with PRIMESTAR(R).
 
RISK OF TECHNOLOGICAL CHANGES
 
  Technology in the digital satellite television industry is subject to rapid
change, and new technologies are continuously being developed. Some
competitors of the Borrower may have or may obtain access to proprietary
technologies that are perceived by the satellite services industry or
customers as superior to, or more desirable than, the technology of the
Borrower and/or the technology used in the PRIMESTAR(R) system. There can be
no assurance that the Borrower could obtain access to any such technology or
that the lack of any such technology would not adversely affect the ability of
the Borrower to compete with such competitors.
 
  In addition, in order to implement successfully its high power business
plan, the Borrower will need access to statistical multiplexing technology or
other advances in digital compression technology that are currently under
development or being tested by several third parties. Such technology would
enable the Borrower to increase the number of digital program signals that
could be transmitted simultaneously over a single satellite transponder, thus
effectively increasing the digital compression ratio. Although the Borrower
does not currently have any agreement with respect to the use of any such
technology, the Borrower believes that the Borrower would be able to obtain
the rights to use such technology. However, in the event that the Borrower
were unable to obtain such rights, its high power business plan could be
adversely affected.
 
ABSENCE OF PUBLIC MARKET FOR THE EXCHANGE NOTES
 
  The Exchange Notes will have been registered under the Securities Act.
However, the Exchange Notes will constitute a new issue of securities with no
established trading market. If a trading market does not develop or is not
maintained, holders of the Exchange Notes may experience difficulty in
reselling the Exchange Notes or may be unable to sell them at all. If a market
for the Exchange Notes develops, any such market may be discontinued at any
time. Although the Initial Purchasers (Donaldson, Lufkin & Jenrette Securities
Corporation, Merrill Lynch, Pierce Fenner & Smith Incorporated, NationsBanc
Capital Markets, Inc. and Scotia Capital Markets (USA) Inc.) have advised the
Borrower that they currently intend to make a market in the Exchange Notes,
they are not obligated to do so and may discontinue such market making
activity at any time without notice. In addition, such market making activity
will be subject to the limits imposed by the Securities Act and the Exchange
Act and may be limited during the Exchange Offer and the pendency of any
Registration Statement with respect to resale of the Notes. Accordingly, there
can be no assurance as to the development or liquidity of any market for the
Exchange Notes. The liquidity of any market for the Exchange Notes will depend
upon the number of holders of such Exchange Notes, the interest of securities
dealers in making a market in the Exchange Notes and other factors. The
liquidity of, and trading markets for, the Exchange Notes may also be
negatively
 
                                      38
<PAGE>
 
affected by general declines in the market for noninvestment grade debt
independent of the financial performance of, or prospects for, the Borrower.
The Borrower does not intend, and the Borrower does not anticipate that the
Borrower will, list the Exchange Notes on any national securities exchange or
to seek the admission thereof to trading in the National Association of
Securities Dealers Automated Quotation System. The Notes currently may be sold
pursuant to the restrictions set forth in Rule 144A or Regulation S, or
pursuant to another available exemption under the Securities Act, without
registration under the Securities Act. See "--Restrictions on Transfer."
 
EXCHANGE OFFER PROCEDURES
 
  Issuance of the Exchange Notes in exchange for Notes pursuant to the
Exchange Offer will be made only after the timely receipt by the Borrower of
such Notes, a properly completed and duly executed Letter of Transmittal and
all other required documents. Therefore, holders of the Notes desiring to
tender such Notes in exchange for Exchange Notes should allow sufficient time
to ensure timely delivery. The Borrower is under no duty to give notification
of defects or irregularities with respect to the tenders of Notes for
exchange. Notes that are not tendered or are tendered but not accepted will,
following the consummation of the Exchange Offer, continue to be subject to
the existing restrictions upon transfer thereof and, upon consummation of the
Exchange Offer, the registration rights under the Registration Rights
Agreements generally will terminate. In addition, any holder of Notes who
tenders in the Exchange Offer for the purpose of participating in a
distribution of the Exchange Notes may be deemed to have received restricted
securities and, if so, will be required to comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale transaction. Each broker-dealer that receives Exchange Notes for its
own account in exchange for Notes, where such Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. To the extent that Notes are tendered
and accepted in the Exchange Offer, the trading market for untendered and
tendered but unaccepted Notes could be adversely affected. See "The Exchange
Offer."
 
                                 THE BORROWER
 
TSAT
 
  Generally. TSAT is a leading distributor of digital satellite-based
television services in the United States. TSAT markets and distributes
PRIMESTAR(R), a medium power digital satellite service, under the brand names
"PRIMESTAR By TCI" and "PRIMESTAR By TSAT" and owns an aggregate 20.86%
interest in the Partnership, which owns and operates the PRIMESTAR(R) service.
As of September 30, 1997, TSAT was the largest distributor of PRIMESTAR(R),
with an installed base of approximately 769,000 subscribers, which represented
approximately 42.7% of the Partnership's estimated 1.8 million subscribers as
of such date. As of September 30, 1997, TSAT's subscribers comprised
approximately 888,000 Authorized Units. As used herein, the term "Authorized
Units" refers to the number of active authorized satellite receivers or IRDs,
more than one of which may be installed in a subscribing household.
PRIMESTAR(R) offers over 160 channels of digital video and audio programming
throughout the continental U.S., via medium power satellite, to home satellite
dishes approximately 27 to 36 inches in diameter for most subscribers.
 
  TSAT was incorporated in Delaware in November 1996. Prior to the Spin-off
Date, TSAT was a wholly-owned subsidiary of TCI, which, through various
subsidiaries, was engaged in the business of distributing PRIMESTAR(R) since
December 1990. TSAT was formed to own and operate TCI's interests in the
digital satellite business, in connection with the TSAT Spin-off. TSAT's
predecessor was incorporated in February 1995 to consolidate TCI's
PRIMESTAR(R) distribution business into one subsidiary, and was merged into
TSAT in connection with the TSAT Spin-off. TCI is one of the two largest
operators of cable systems in the U.S.
 
  TSAT Series A Common Stock and TSAT Series B Common Stock trade on the
Nasdaq National Market under the symbols "TSATA" and "TSATB," respectively.

TSAT's principal executive offices are 8085 South Chester, Suite 300,
Englewood, Colorado 80112, (303) 712-4600.
 
  Tempo. Tempo, a wholly-owned subsidiary of TSAT, holds the FCC Permit,
authorizing construction of a high power DBS system consisting of two or more
satellites delivering DBS service in 11 frequencies at the 119(degrees) W.L.
orbital position and 11 frequencies at the 166(degrees) W.L. orbital position.
The 119(degrees) W.L. orbital position is one of three such orbital positions
available for DBS service to the U.S. which are "full CONUS," meaning that
they have a view of the entire continental U.S.
 
  Tempo is also a party to the Satellite Construction Agreement with Loral,
pursuant to which Tempo has arranged for the construction of the two Tempo
Satellites and has an option to purchase up to three additional satellites.
Construction of the Tempo Satellites has been completed. Tempo DBS-1 was
launched into TSAT's high power slot at 119(degrees) W.L. on March 8, 1997.
The other Tempo Satellite, Tempo DBS-2, presently serves as a ground spare for
Tempo DBS-1.
 
  Tempo DBS-1 is currently undergoing extended in-orbit testing under the
Satellite Construction Agreement. Assuming that such in-orbit testing results
in acceptance of the satellite by Tempo under the Satellite Construction
Agreement, Tempo DBS-1 would be available for commercial operations in the
first quarter of 1998. At current levels of digital compression, Tempo
believes that Tempo DBS-1 would be able to deliver approximately 100 channels
of digital video and 20 channels of digital audio programming, as operated
under the FCC Permit. Tempo expects to use 18 inch dishes for the proposed
high power service, the same diameter currently used by other high power DBS
providers, in most areas. Tempo currently intends to operate Tempo DBS-1 as a
platform to provide high power digital video and audio programming services to
residential customers, as well as MDUs, commercial customers and resellers.
 
  The availability and utility of Tempo DBS-1, including the power levels
provided by Tempo DBS-1, are subject to risks of satellite defect, loss or
reduced performance. Since the launch of Tempo DBS-1, Loral has notified Tempo
of at least five separate occurrences of power reductions on Tempo DBS-1. No
assurance can be given that further power reductions will not occur in the
future. TSAT does not currently know the extent of such power reductions, and
cannot confirm the precise causes thereof; however, such reductions could
eventually affect the proposed operation of Tempo DBS-1, either alone or
together with other events that may arise during the expected life of the
satellite. See "Risk Factors--Risks of Satellite Failure."
 
  Pursuant to the Tempo Option Agreement, Tempo has agreed to sell or lease to
the Partnership 100% of the capacity of any DBS system constructed by Tempo
under the FCC Permit. In connection with the execution and delivery of the
Restructuring Agreement, TSAT and New PRIMESTAR entered into the TSAT Tempo
Agreement dated as of February 6, 1998 (the "TSAT Tempo Agreement"), pursuant
to which, among other things, TSAT granted to New PRIMESTAR (together with its
successors and assigns, the "Option Holder") the exclusive and irrevocable
option (the "Tempo Sale Option"), exercisable at any time during the term of
the TSAT Tempo Agreement, on the terms and subject to the conditions set forth
in the TSAT Tempo Agreement, upon receipt of FCC approval of the transfer of
control of Tempo to New PRIMESTAR (including approval of a transfer in
anticipation of a subsequent sale), to purchase from TSAT (at the Option
Holder's election) either (x) all the issued and outstanding shares of capital
stock of Tempo or (y) all the rights, title and interests of TSAT in, to and
under the Tempo Assets (as defined below), in either case for an aggregate
purchase price equal to $2.5 million plus, in the case of (y), the assumption
by the Option Holder of all obligations and liabilities of Tempo in respect of
the Tempo Assets, other than those incurred in violation of the TSAT Tempo
Agreement (either such transaction being referred to herein as the "Tempo
Sale"). If the Option Holder exercises the Tempo Sale Option and elects to
consummate the Tempo Sale via clause (y) above, then TSAT will liquidate Tempo
immediately prior to the closing of the Tempo Sale. The Option Holder, in its
sole discretion, is entitled to assign the TSAT Tempo Agreement and New
PRIMESTAR's rights, interests and obligations thereunder at any time. "Tempo
Assets" means (i) the FCC Permit, (ii) the Tempo Satellites, (iii) the
Satellite Construction Agreement, and (iv) all rights, claims and causes of
action under the Satellite Construction Agreement, all insurance claims in
respect of the Tempo Satellites, and Tempo's rights under the Tempo Option
Agreement. If the TSAT Merger
 
                                      40
<PAGE>
 
or the Tempo Sale is consummated, New PRIMESTAR will operate Tempo's high
power DBS system. Otherwise, TSAT expects that such system will be utilized by
the Partnership pursuant to the Tempo Option Agreement. See "Risk Factors--
Uncertainty Regarding High Power Strategies."
 
OTHER RESTRUCTURING PARTIES
 
  The Partnership. The Partnership owns and operates PRIMESTAR(R), which is
the oldest Ku-band satellite television service in the U.S. and has the second
largest subscriber base of any U.S. digital satellite television service. In
1990, direct or indirect subsidiaries of TCI and several other large cable
operators and GEAS, an indirect subsidiary of GE, formed the Partnership to
acquire, originate and/or provide television programming services for delivery
by satellite to subscribers in the continental U.S. Initially, PRIMESTAR(R)
was an analog service limited to seven broadcast television superstations, TV
Japan and three pay-per-view stations. In 1994, PRIMESTAR(R) was among the
first satellite television services to use digital transmission and
compression technology to offer laser-disc-quality image and compact-disc-
quality sound. The Partnership has consistently taken advantage of
technological improvements and additional available transponder capacity to
improve the PRIMESTAR(R) service, which today offers over 160 channels of
digital video and audio programming.
 
  In addition to TSAT, the Partners include (i) Cox SI, a subsidiary of Cox,
(ii) Comcast DBS, a subsidiary of Comcast, (iii) Continental, a subsidiary of
US WEST, Inc., the parent of MediaOne, (iv) New Vision Satellite, a
partnership controlled by Newhouse, which is a subsidiary of Newhouse
Broadcasting, (v) TW Programming Co., a partnership controlled by TWE, which
is a subsidiary of Time Warner, and (vi) GEAS, a subsidiary of GE, the parent
of GE Americom. Each of TSAT (through its subsidiaries) and TW Programming Co.
holds a 20.86% Partnership Interest, each of Cox SI, Comcast DBS, Continental
and New Vision Satellite holds a 10.43% Partnership Interest, and GEAS holds a
16.56% Partnership Interest. Time Warner has substantial interests, through
its subsidiaries and controlled partnerships, in video programming and
distribution, and is one of the two largest operators of cable systems in the
U.S. Cox, Comcast and MediaOne are also among the five largest cable system
operators.
 
  Pursuant to the Partnership Agreement, the business and affairs of the
Partnership are managed and controlled by the Partners Committee, which is
composed of representatives of each of the Partners and two independent
members. TSAT has two voting representatives on the Partners Committee, Time
Warner has two voting representatives, and Cox, Comcast, MediaOne, Newhouse
and GE each have one voting representative.
 
  The PRIMESTAR(R) programming service includes a variety of advertiser-
supported networks (sometimes referred to as "basic cable" channels), a broad
selection of movie services, national and regional sports packages and other
premium services, and multiplexed pay-per-view programming. The Partnership
secures its rights to transmit such programming via satellite by entering into
non-exclusive affiliation agreements with programming vendors. In addition to
video services, PRIMESTAR(R) includes digital audio and data services,
including Ingenius, which provides access to news, business news, stock
quotes, sports, weather and entertainment information to subscribers through
their personal computers.
 
  The Partnership currently plans to participate in the high power segment of
the digital satellite industry. In that connection, the Partnership has agreed
to purchase or lease from Tempo 100% of the capacity of any DBS system
constructed by Tempo under the FCC Permit pursuant to the Tempo Option
Agreement. In addition, the Partnership has entered into the ASkyB Agreement,
which provides for the sale and transfer to New PRIMESTAR of the MCI
Satellites), certain authorizations granted to MCI by the FCC to operate a DBS
business at the 110(degrees) W.L. orbital location using 28 transponder
channels, and certain related contracts. The ASkyB Agreement requires New
PRIMESTAR to bear certain risks in connection with the process of obtaining
the regulatory approval related to such transfers, including the divestiture
of all rights of the Partnership and any of the Partners under Tempo's FCC
authorizations with respect to the 11 transponder channels at 119(degrees)
W.L., if required as a condition to such approval. Consummation of the ASkyB
Transaction is contingent on, among other things, receipt of all necessary
government and regulatory approvals, and accordingly, no assurance can be
given that the ASkyB Transaction will be consummated.

  Other PRIMESTAR(R) Distributors. PRIMESTAR(R) is distributed through TSAT
and the other Distributors, each of which is currently affiliated with one or
more of the Partners. The Distributors market the PRIMESTAR(R) service and
contract with subscribers, in non-exclusive territories assigned by the
Partnership. The Distributors set their own retail pricing and are responsible
in their respective territories for authorization of subscribers,
installation, maintenance and retrieval of customer premises equipment, and
billing and collection of monthly and other fees, and the Distributors bear
all risks of loss relating thereto. The Partnership performs certain
administrative functions for the Distributors, including program acquisition,
national marketing, transponder leasing and certain technical functions, and
passes along the costs relating thereto to the Distributors.
 
  New PRIMESTAR. New PRIMESTAR, a newly formed Delaware corporation, is a
wholly-owned subsidiary of TSAT that has not conducted any significant
activities other than those incident to its formation, the execution of the
Restructuring Agreement, the TSAT Merger Agreement and Asset Transfer
Agreements, and related financing activities relating to the Restructuring
Transaction. As a result of the pending Restructuring Transaction and pursuant
to the Restructuring Agreement, the Merger Agreements and the Asset Transfer
Agreements, New PRIMESTAR will acquire the TSAT Business, the Partnership
Interests of the other Partners and the PRIMESTAR Assets of the other
Distributors. It is expected that, measured by the number of subscribers, New
PRIMESTAR will be the second largest provider of satellite television services
in the United States. The mailing address and the telephone number of New
PRIMESTAR's principal executive offices are 8085 South Chester, Suite 300,
Englewood Colorado 80122, (303) 712-4600.
 
THE ROLL-UP PLAN
 
  Restructuring Transaction. On February 6, 1998, TSAT entered into (i) the
Restructuring Agreement, (ii) the TSAT Asset Transfer Agreement and (iii) the
TSAT Merger Agreement. The transactions contemplated under the Restructuring
Agreement and the TSAT Asset Transfer Agreement comprise the Restructuring
Transaction, which, if consummated, shall result in New PRIMESTAR's owning the
entire PRIMESTAR(R) digital satellite business. Upon consummation of the
Restructuring Transaction, TSAT and its former partners in that business (or
their respective affiliates) will, in the aggregate, own all the outstanding
capital stock of New PRIMESTAR.
 
  The proposed Restructuring Transaction provides for, among other things, the
following transactions to occur on the closing date of the Restructuring
Transaction:
 
    (x) the contribution and transfer by TSAT to New PRIMESTAR pursuant to
  the TSAT Asset Transfer Agreement (the "TSAT Asset Transfer") of all of the
  assets and liabilities of TSAT (including, among other things, the Notes
  and the Exchange Notes), except (i) the capital stock of Tempo, (ii) the
  consideration to be received by TSAT in the Restructuring Transaction and
  (iii) the rights and obligations of TSAT under certain agreements with New
  PRIMESTAR. Concurrently with the consummation of the TSAT Asset Transfer,
  New PRIMESTAR will adopt the New PRIMESTAR Charter and bylaws ("New
  PRIMESTAR Bylaws");
 
    (y) the merger (each a "Merger" and, collectively, the "Mergers") of each
  of (I) Comcast DBS, a subsidiary of Comcast whose sole asset is Comcast's
  10.43% interest in the Partnership, (II) Comcast SCI, a subsidiary of
  Comcast that holds Comcast's PRIMESTAR(R) distribution business, (III) Cox
  SI, a subsidiary of Cox that holds Cox's 10.43% interest in the Partnership
  and Cox's PRIMESTAR(R) distribution business, and (IV) GEAS, a subsidiary
  of GE Americom that holds GE Americom's 16.56% interest in the Partnership,
  with and into New PRIMESTAR, in each case in accordance with the terms of a
  merger agreement with New PRIMESTAR dated as of February 6, 1998 (each, a
  "Merger Agreement" and, collectively, the "Merger Agreements"); and
 
    (z) the contribution and transfer to New PRIMESTAR by each of TWE,
  Newhouse and MediaOne (or, in the case of MediaOne, certain subsidiaries of
  MediaOne) of its respective Partnership Interest, and its PRIMESTAR(R)

  to be acquired by New PRIMESTAR in the Restructuring Transaction, the
  "PRIMESTAR Assets") and related liabilities (collectively the "PRIMESTAR
  Liabilities"), in each case in accordance with the terms of an asset
  transfer agreement with New PRIMESTAR dated as of February 6, 1998. The
  TSAT Asset Transfer and the contribution and transfer of assets by each of
  TWE, Newhouse and MediaOne are each sometimes referred to herein as an
  "Asset Transfer" and collectively as the "Asset Transfers," and the TSAT
  Asset Transfer Agreement and the asset transfer agreements between New
  PRIMESTAR and each of TWE, Newhouse and MediaOne (and certain of its
  subsidiaries) are each sometimes referred to herein as an "Asset Transfer
  Agreement" and collectively as the "Asset Transfer Agreements." In
  addition, references herein to "MediaOne" include the subsidiaries of
  MediaOne that are parties to MediaOne's Asset Transfer Agreement with New
  PRIMESTAR, unless the context otherwise requires.
 
  In connection with the Mergers and the Asset Transfers, each of TSAT,
Comcast, Cox, MediaOne, Newhouse, TWE and GE Americom will, directly or
indirectly, receive from New PRIMESTAR (i) in the case of Cox and MediaOne, an
amount of cash, and in the case of TSAT, Newhouse, TWE, Comcast and GE
Americom, an assumption of indebtedness by New PRIMESTAR, (ii) shares of New
PRIMESTAR Class A Common Stock, (iii) in the case of TSAT only, shares of New
PRIMESTAR Class B Common Stock, and (iv) except in the case of TSAT and GE
Americom, shares of New PRIMESTAR Class C Common Stock, in each case in an
amount determined pursuant to the Restructuring Agreement.
 
  Under the terms of the Restructuring Agreement, TSAT will own approximately
36% of the outstanding shares of common equity of New PRIMESTAR at the closing
of the Restructuring Transaction, and TWE and Newhouse (collectively),
Comcast, MediaOne, Cox and GE Americom will own approximately 31%, 10%, 9%, 9%
and 5%, respectively, of the outstanding shares of common equity of New
PRIMESTAR at closing, subject in each case to adjustments based on closing
subscriber counts.
 
  TSAT Merger. The Restructuring Transaction comprises the first step in
TSAT's proposed two-step Roll-up Plan. The second step of the Roll-up Plan
consists of the TSAT Merger, pursuant to which TSAT shall merge with and into
New PRIMESTAR, with New PRIMESTAR as the surviving corporation, in accordance
with the TSAT Merger Agreement. It is expected that the TSAT Merger shall be
consummated after the consummation of the Restructuring Transaction.
Consummation of the Restructuring Transaction and the TSAT Merger are subject
to approval of the stockholders of TSAT. TSAT has called a special meeting of
its stockholders, to be held on March 6, 1998, to consider and vote upon the
Restructuring Transaction and the TSAT Merger. In addition, the TSAT Merger is
subject to regulatory approval and other closing conditions set forth in the
TSAT Merger Agreement; accordingly, although the Roll-up Plan envisions that
the TSAT Merger will be consummated upon the consummation of the Restructuring
Transaction, there can be no assurance that the TSAT Merger will be
consummated, even if the Restructuring Transaction is consummated.
 
  In connection with the TSAT Merger (i) each outstanding share of TSAT Series
A Common Stock will be converted into the right to receive one share of New
PRIMESTAR Class A Common Stock and (ii) each outstanding share of TSAT Series
B Common Stock will be converted into the right to receive one share of New
PRIMESTAR Class B Common Stock. Each share of New PRIMESTAR's common stock
then held by TSAT will be canceled. As a result of the TSAT Merger,
stockholders of TSAT, at closing, will own approximately 34% of the
outstanding shares of New PRIMESTAR Common Stock.

                              THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
  The Notes were sold by the Borrower on February 20, 1997, and were
subsequently placed with qualified institutional buyers in reliance on Rule
144A under the Securities Act. The aggregate net proceeds from the issuance of
the Notes (approximately $340 million after deducting offering costs) were
initially held in escrow and were subsequently released to TSAT on March 17,
1997. TSAT used $244 million of such net proceeds to repay amounts outstanding
under the Bank Credit Facility. Maximum commitments under the Bank Credit
Facility ($750 million at December 31, 1997) are reduced quarterly commencing
March 31, 2001 until final maturity at June 30, 2005. Amounts outstanding
under the Bank Credit Facility accrue interest at a variable rate of interest,
which, at December 31, 1997, was equal to 7.2%. In connection with the Notes
Offering, the Borrower entered into the Registration Rights Agreements, which
require, among other things, that promptly following the sale of the Notes,
the Borrower would (i) file with the SEC a registration statement under the
Securities Act with respect to corresponding new notes of the Borrower
identical in all material respects to the Notes, (ii) use its best efforts to
cause such registration statement to become effective under the Securities Act
and (iii) upon the effectiveness of such registration statement, offer to the
holders of the Notes the opportunity to exchange their Notes for a like
principal amount of Exchange Notes, which would be issued without a
restrictive legend and may be reoffered and resold by the holder without
restrictions or limitations under the Securities Act (other than in the case
of any such holder that is an "affiliate" of the Borrower within the meaning
of Rule 405 under the Securities Act). Copies of the Registration Rights
Agreements have been filed as an exhibit to the Registration Statement of
which this Prospectus is a part.
 
  The Exchange Offer is for any and all Notes, and thus, the number of Notes
tendered and exchanged in the Exchange Offer will reduce the principal amount
of Notes outstanding. Following the consummation of the Exchange Offer,
holders of the Notes who did not tender their Notes will not have any further
registration rights under the Registration Rights Agreements, and such Notes
will continue to be subject to certain restrictions on transfer. Accordingly,
the liquidity of the market for such Notes could be adversely affected. The
Notes are currently eligible for sale pursuant to Rule 144A through the PORTAL
System of the National Association of Securities Dealers, Inc. In light of the
absence of resale restrictions on the Exchange Notes under the Securities Act,
the Borrower anticipates that most holders of Notes will elect to exchange
such Notes for Exchange Notes, and accordingly, the Borrower anticipates that
the liquidity of the market for any Notes remaining after the consummation of
the Exchange Offer may be substantially limited.
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Borrower will accept any and all Notes
validly tendered and not withdrawn prior to 5:00 p.m. New York City time on
the Expiration Date. The Borrower will issue $1,000 principal amount of
Exchange Notes in exchange for $1,000 principal amount of outstanding Notes
accepted in the Exchange Offer. Holders may tender some or all of their Notes
pursuant to the Exchange Offer. However, Notes may be tendered only in
integral multiples of $1,000.
 
  The form and terms of the Exchange Notes are the same as the form and terms
of the Notes except that (i) the Exchange Notes have been registered under the
Securities Act and hence will not bear legends restricting the transfer
thereof thereunder and (ii) the holders of the Exchange Notes will not be
entitled to certain rights under the Registration Rights Agreements (such
rights are hereafter referred to as "Registration Rights"). Holders of Notes
currently have Registration Rights under the Registration Rights Agreement,
but such Registration Rights will generally terminate upon consummation of the
Exchange Offer. The Exchange Notes will evidence the same debt as the Notes
and will be entitled to the benefits set forth in the Indentures, except such
benefits that, by their terms, terminate or cease to have any effectiveness as
a result of the Exchange Offer.
 
  As of the date of this Prospectus, (i) $200,000,000 aggregate principal
amount of the Senior Subordinated Notes was outstanding, all of which was
registered in the name of Cede & Co., as nominee for the Depository,
 
                                      44
<PAGE>
 
and (ii) $275,000,000 aggregate principal amount at maturity of the Senior
Subordinated Discount Notes was outstanding, all of which was registered in
the name of Cede & Co., as nominee for the Depository. The Borrower has fixed
the close of business on February 26, 1998 as the record date for the Exchange
Offer for purposes of determining the persons to whom this Prospectus and the
Letter of Transmittal will be mailed initially.
 
  Holders of Notes do not have any appraisal or dissenters' rights under the
General Corporation Law of Delaware or the Indentures in connection with the
Exchange Offer. The Borrower intends to conduct the Exchange Offer in
accordance with the applicable requirements of the Exchange Act and the rules
and regulations of the SEC thereunder, including Rule 14e-1 thereunder.
 
  The Borrower shall be deemed to have accepted validly tendered Notes when,
as and if the Borrower has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purpose of receiving the Exchange Notes from the Borrower.
 
  If any tendered Notes are not accepted for exchange because of an invalid
tender, the occurrence of certain other events set forth herein or otherwise,
the certificates for any such unaccepted Notes will be returned, without
expense, to the tendering holder thereof as promptly as practicable after the
Expiration Date.
 
  Holders who tender Notes in the Exchange Offer will not be required to pay
brokerage commissions or fees or, subject to the instructions in the Letter of
Transmittal, transfer taxes with respect to the exchange of Notes pursuant to
the Exchange Offer. The Borrower will pay all charges and expenses, other than
transfer taxes in certain circumstances, in connection with the Exchange
Offer. See "--Fees and Expenses." The Borrower will not receive any proceeds
from the Exchange Offer.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
March 30, 1998, unless the Borrower, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.
 
  To extend the Exchange Offer, the Borrower will notify the Exchange Agent of
any extension by oral or written notice and will mail to the registered
holders an announcement thereof, each prior to 9:00 a.m., New York City time,
on the next business day after the previously scheduled expiration date.
 
  The Borrower reserves the right, in its reasonable judgment, (i) to delay
accepting any Notes, to extend the Exchange Offer or to terminate the Exchange
Offer if any of the conditions set forth below under "--Conditions" shall not
have been satisfied, by giving oral or written notice of such delay, extension
or termination to the Exchange Agent and (ii) to amend the terms of the
Exchange Offer in any manner. Any such delay in acceptance, extension,
termination or amendment will be followed as promptly as practicable by oral
or written notice thereof to the registered holders. If the Exchange Offer is
amended in a manner determined by the Borrower to constitute a material
change, the Borrower will promptly disclose such amendment by means of a
prospectus supplement that will be distributed to the registered holders, and,
depending upon the significance of the amendment and the manner of disclosure
to the registered holders, the Borrower will extend the Exchange Offer for a
period of five to ten business days if the Exchange Offer would otherwise
expire during such five to ten business day period.
 
  If the Borrower does not consummate the Exchange Offer, or, in lieu thereof,
the Borrower does not file and cause to become effective a resale shelf
registration for the Notes within the time periods set forth herein, special
interest will accrue and be payable on the Notes either temporarily or
permanently. See "Description of Exchange Notes--Registration Covenant;
Exchange Offer."
 
  Without limiting the manner in which the Borrower may choose to make public
announcement of any delay, extension, amendment or termination of the Exchange
Offer, the Borrower shall have no obligation to publish,
 
                                      45
<PAGE>
 
advertise or otherwise communicate any such public announcement, other than by
making a timely release to the Dow Jones News Service.
 
INTEREST ON EXCHANGE NOTES
 
  Cash interest on the Senior Subordinated Exchange Notes will accrue at a
rate of 10 7/8% per annum, commencing February 20, 1997, the date of issuance
of the Notes, and will be payable semi-annually in arrears on each February 15
and August 15, commencing August 15, 1998. See "Description of the Exchange
Notes--Maturity, Interest and Principal of the Senior Subordinated Notes."
Accordingly, holders of Senior Subordinated Notes that are accepted for
exchange will not receive interest that is accrued but unpaid on such Notes at
the time of tender.
 
  Cash interest will not accrue or be payable on the Senior Subordinated
Discount Exchange Notes prior to February 15, 2002. Thereafter, cash interest
on the Senior Subordinated Discount Exchange Notes will accrue at a rate of 12
1/4% per annum and will be payable semi-annually in arrears on each February
15 and August 15, commencing August 15, 2002; provided, however, that at any
time prior to February 15, 2002, the Borrower may make a Cash Interest
Election on any interest payment date to commence the accrual of cash interest
from and after the Cash Interest Election Date, in which case the outstanding
principal amount at maturity of each Senior Subordinated Discount Exchange
Note will on such interest payment date be reduced to the Accreted Value of
such Senior Subordinated Discount Exchange Note as of such interest payment
date, and cash interest (accruing at a rate of 12 1/4% per annum from the Cash
Interest Election Date) shall be payable with respect to such Senior
Subordinated Discount Exchange Note on each interest payment date thereafter.
See "Description of the Exchange Notes--Maturity, Interest and Principal of
the Senior Subordinated Discount Notes."
 
  The Senior Subordinated Notes were issued at par. The Senior Subordinated
Discount Notes were issued at a discount to their aggregate principal amount
at maturity, with a yield to maturity calculated from the issuance date of 12
1/4% (computed on a semi-annual bond equivalent basis). In the Exchange Offer,
properly tendering holders will receive Senior Subordinated Discount Exchange
Notes having an aggregate principal amount at maturity equal to the aggregate
principal amount at maturity of the Senior Subordinated Discount Notes so
tendered. Accordingly, holders of Senior Subordinated Discount Notes that are
accepted for exchange will not receive payment for any increase in Accreted
Value on such Notes at the time of tender.
 
PROCEDURES FOR TENDERING
 
  Only a holder of Notes may tender such Notes in the Exchange Offer. To
tender in the Exchange Offer, a holder must complete, sign and date the Letter
of Transmittal, or a facsimile thereof, have the signatures thereon guaranteed
if required by the Letter of Transmittal and mail or otherwise deliver such
Letter of Transmittal or such facsimile, together with the Notes and any other
required documents, to the Exchange Agent prior to 5:00 p.m., New York City
time, on the Expiration Date. To be tendered effectively, the Notes, Letter of
Transmittal and other required documents must be received by the Exchange
Agent at the address set forth below under "Exchange Agent" prior to 5:00
p.m., New York City time, on the Expiration Date. Delivery of the Notes may be
made by book-entry transfer in accordance with the procedures described below.
Confirmation of such book-entry transfer must be received by the Exchange
Agent prior to the Expiration Date.
 
  By executing the Letter of Transmittal, each holder will make to the
Borrower the representation set forth below in the second paragraph under the
heading "Resale of Exchange Notes."
 
  The tender by a holder and the acceptance thereof by the Borrower will
constitute an agreement between such holder and the Borrower in accordance
with the terms and subject to the conditions set forth herein and in the
Letter of Transmittal.
 
  THE METHOD OF DELIVERY OF NOTES AND THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT
 
                                      46
<PAGE>
 
HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE. IN ALL CASES, SUFFICIENT
TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE
EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR NOTES SHOULD BE SENT TO THE
BORROWER. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL
BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH
HOLDERS.
 
  Any beneficial owner whose Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to
tender should contact the registered holder promptly and instruct such
registered holder to tender on such beneficial owner's behalf.
 
  Signatures on the Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined below)
unless the Notes tendered pursuant thereto are tendered (i) by a registered
holder who has not completed the box entitled "Special Registration
Instructions" or "Special Delivery Instructions" on the Letter of Transmittal
or (ii) for the account of an Eligible Institution. In the event that
signatures on a Letter of Transmittal or a notice of withdrawal, as the case
may be, are required to be guaranteed, such guarantee must be by a member firm
of a registered national securities exchange or of the National Association of
Securities Dealers, Inc., a commercial bank or trust company having an office
or correspondent in the United States or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Exchange Act (an "Eligible
Institution").
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Notes listed therein, such Notes must be endorsed or accompanied
by a properly completed bond power, signed by such registered holder as such
registered holder's name appears on such Notes with the signature thereon
guaranteed by an Eligible Institution.
 
  If the Letter of Transmittal or any Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and unless waived by the Borrower,
evidence satisfactory to the Borrower of their authority to so act must be
submitted with the Letter of Transmittal.
 
  The Borrower understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish accounts with respect
to the Notes at the Depository (the "Book-Entry Transfer Facility") for the
purpose of facilitating the Exchange Offer, and subject to the establishment
thereof, any financial institution that is a participant in the Book-Entry
Transfer Facility's system may make book-entry delivery of the Notes by
causing the Book- Entry Transfer Facility to transfer such Notes into the
Exchange Agent's account with respect to the Notes in accordance with the
Book-Entry Transfer Facility's procedures for such transfer. Although delivery
of the Notes may be effected through book-entry transfer into the Exchange
Agent's account at the Book-Entry Transfer Facility, an appropriate Letter of
Transmittal properly completed and duly executed with any required signature
guarantee and all other required documents must in each case be transmitted to
and received or confirmed by the Exchange Agent at its address set forth below
on or prior to the Expiration Date, or, if the guaranteed delivery procedures
described below are complied with, within the time period provided under such
procedures. Delivery of documents to the Book-Entry Transfer Facility does not
constitute delivery to the Exchange Agent.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Notes and withdrawal of tendered Notes will
be determined by the Borrower in its sole discretion, which determination will
be final and binding. The Borrower reserves the absolute right to reject any
and all Notes not properly tendered or any Notes the Borrower's acceptance of
which would, in the opinion of counsel for the Borrower, be unlawful. The
Borrower also reserves the right to waive any defects, irregularities or
conditions of tender as to particular Notes. The Borrower's interpretation of
the terms and conditions of the Exchange Offer (including the instructions in
the Letter of Transmittal) will be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Notes must
be cured within such time as the Borrower shall
 
                                      47
<PAGE>
 
determine. Although the Borrower intends to notify holders of defects or
irregularities with respect to tenders of Notes, neither the Borrower, the
Exchange Agent nor any other person shall incur any liability for failure to
give such notification. Tenders of Notes will not be deemed to have been made
until such defects or irregularities have been cured or waived. Any Notes
received by the Exchange Agent that are not properly tendered and as to which
the defects or irregularities have not been cured or waived will be returned
by the Exchange Agent to the tendering holders, unless otherwise provided in
the Letter of Transmittal, as soon as practicable following the Expiration
Date.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Notes and (i) whose Notes are not
immediately available, (ii) who cannot deliver their Notes, the Letter of
Transmittal or any other required documents to the Exchange Agent or (iii) who
cannot complete the procedures for book-entry transfer, prior to the
Expiration Date, may effect a tender if:
 
    (a) the tender is made through an Eligible Institution;
 
    (b) prior to the Expiration Date, the Exchange Agent receives from such
  Eligible Institution a properly completed and duly executed Notice of
  Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
  setting forth the name and address of the holder, the certificate number(s)
  of such Notes and the principal amount of Notes tendered, stating that the
  tender is being made thereby and guaranteeing that, within three New York
  Stock Exchange trading days after the Expiration Date, the Letter of
  Transmittal (or facsimile thereof), together with the certificates(s)
  representing the Notes (or a confirmation of book-entry transfer of such
  Notes into the Exchange Agent's account at the Book-Entry Transfer
  Facility) and any other documents required by the Letter of Transmittal,
  will be deposited by the Eligible Institution with the Exchange Agent; and
 
    (c) such properly completed and executed Letter of Transmittal (or
  facsimile thereof), as well as the certificate(s) representing all tendered
  Notes in proper form for transfer (or a confirmation of book-entry transfer
  of such Notes into the Exchange Agent's account at the Book-Entry Transfer
  Facility) and all other documents required by the Letter of Transmittal,
  are received by the Exchange Agent within three New York Stock Exchange
  trading days after the Expiration Date.
 
  Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Notes according to the guaranteed
delivery procedures set forth above.
 
WITHDRAWALS OF TENDERS
 
  Except as otherwise provided herein, tenders of Notes may be withdrawn at
any time prior to 5:00 p.m., New York City time, on the Expiration Date.
 
  To withdraw a tender of Notes in the Exchange Offer, a written or facsimile
transmission notice of withdrawal must be received by the Exchange Agent at
its address set forth herein prior to 5:00 p.m., New York City time, on the
Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Notes to be withdrawn (the "Depositor"), (ii)
identify the Notes to be withdrawn (including the certificate number(s) and
principal amount of such Notes, or, in the case of Notes transferred by book-
entry transfer, the name and number of the account at the Book-Entry Transfer
Facility to be credited), (iii) be signed by the holder in the same manner as
the original signature on the Letter of Transmittal by which such Notes were
tendered (including any required signature guarantees) or be accompanied by
documents of transfer sufficient to have the Trustee with respect to the Notes
register the transfer of such Notes into the name of the person withdrawing
the tender and (iv) specify the name in which any such Notes are to be
registered, if different from that of the Depositor. All questions as to the
validity, form and eligibility (including time of receipt) of such notices
will be determined by the Borrower, whose determination shall be final and
binding on all parties. Any Notes so withdrawn will be deemed not to have been
validly tendered for purposes of the Exchange Offer and no Exchange Notes will
be issued with respect thereto unless the Notes so withdrawn are validly
retendered. Any Notes which have been tendered but which are not accepted for
exchange will be returned to the holder
 
                                      48
<PAGE>
 
thereof without cost to such holder as soon as practicable after withdrawal,
rejection of tender or termination of the Exchange Offer. Properly withdrawn
Notes may be retendered by following one of the procedures described above
under "--Procedures for Tendering" at any time prior to the Expiration Date.
 
CONDITIONS
 
  Notwithstanding any other term of the Exchange Offer, the Borrower shall not
be required to accept for exchange, or to exchange Exchange Notes for, any
Notes, and may terminate or amend the Exchange Offer as provided herein before
the acceptance of such Notes, if:
 
    (a) any law, statute, rule, regulation or interpretation by the staff of
  the SEC is proposed, adopted or enacted, which, in the sole judgment of the
  Borrower, might materially impair the ability of the Borrower to proceed
  with the Exchange Offer or materially impair the contemplated benefits of
  the Exchange Offer to the Borrower; or
 
    (b) any governmental approval has not been obtained, which approval the
  Borrower shall, in its sole discretion, deem necessary for the consummation
  of the Exchange Offer as contemplated hereby.
 
  If the Borrower determines in its reasonable judgment that any of the
conditions are not satisfied, the Borrower may (i) refuse to accept any Notes
and return all tendered Notes to the tendering holders, (ii) extend the
Exchange Offer and retain all Notes tendered prior to the expiration of the
Exchange Offer, subject, however, to the rights of holders to withdraw such
Notes (see "--Withdrawal of Tenders") or (iii) waive such unsatisfied
conditions with respect to the Exchange Offer and accept all properly tendered
Notes which have not been withdrawn. If such waiver constitutes a material
change to the Exchange Offer, the Borrower will promptly disclose such waiver
by means of a prospectus supplement that will be distributed to the registered
holders, and, depending upon the significance of the waiver and the manner of
disclosure to the registered holders, the Borrower will extend the Exchange
Offer for a period of five to ten business days if the Exchange Offer would
otherwise expire during such five to ten business-day period.

FEES AND EXPENSES
 
  The expenses of soliciting tenders will be borne by the Borrower. The
principal solicitation is being made by mail; however, additional
solicitations may be made by telegraph, telephone or in person by officers and
regular employees of the Borrower and its affiliates.
 
  The Borrower has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers or other persons
soliciting acceptances of the Exchange Offer. The Borrower, however, will pay
the Exchange Agent reasonable and customary fees for its services and will
reimburse it for its reasonable out-of-pocket expenses in connection therewith
and pay other registration expenses, including fees and expenses of the
Trustee, filing fees, blue sky fees and printing and distribution expenses.
 
  The Borrower will pay all transfer taxes, if any, applicable to the exchange
of the Notes pursuant to the Exchange Offer. If, however, certificates
representing the Exchange Notes or the Notes for principal amounts not
tendered or accepted for exchange are to be delivered to, or are to be issued
in the name of, any person other than the registered holder of the Notes
tendered, or if tendered Notes are registered in the name of any person other
than the person signing the Letter of Transmittal, or if a transfer tax is
imposed for any reason other than the exchange of the Notes pursuant to the
Exchange Offer, then the amount of any such transfer taxes (whether imposed on
the registered holder or any other person) will be payable by the tendering
holder.
 
ACCOUNTING TREATMENT
 
  The Exchange Notes will be recorded at the same carrying value as the Notes,
as reflected in the Borrower's accounting records on the date of exchange.
Accordingly, no gain or loss for accounting purposes will be recognized.
 
RESALE OF EXCHANGE NOTES
 
  Based on an interpretation by the staff of the SEC set forth in no-action
letters issued to third parties, the Borrower believes that Exchange Notes
issued pursuant to the Exchange Offer in exchange for Notes may be offered for
resale, resold and otherwise transferred by any holder of such Exchange Notes
(other than any such holder which is an "affiliate" of the Borrower within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act,
provided that such Exchange Notes are acquired in the ordinary course of such
holder's business and such holder does not intend to participate, and has no
arrangement or understanding with any person to participate, in the
distribution of such Exchange Notes. Any holder who tenders in the Exchange
Offer with the intention to participate, or for the purpose of participating,
in a distribution of the Exchange Notes may not rely on the position of the
staff of the SEC enunciated in Exxon Capital Holdings Corporation (available
April 13, 1989) and Morgan Stanley & Co., Incorporated (available June 5,
1991), or similar no-action letters, but rather must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. In addition, any such resale
transaction should be covered by an effective registration statement
containing the selling security holders information required by Item 507 of
Regulation S-K of the Securities Act. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Notes, where such Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities, may be a statutory underwriter and must acknowledge
that it will deliver a prospectus in connection with any resale of such
Exchange Notes.
 
  Broker-dealers who have acquired Notes directly from TSAT are not permitted
to exchange such Notes in the Exchange Offer.
 
                                      50

  By tendering in the Exchange Offer, each holder will represent to the
Borrower that, among other things, (i) any Exchange Notes to be received by
the holder are being acquired in the ordinary course of its business, (ii) the
holder has no arrangement or understanding with any person to participate in a
distribution (within the meaning of the Securities Act) of Exchange Notes to
be received in the Exchange Offer, and (iii) if the holder is not a broker-
dealer, the holder is not engaged in, and does not intend to engage in, a
distribution (within the meaning of the Securities Act) of such Exchange
Securities. By tendering Notes pursuant to the Exchange Offer and executing
the Letter of Transmittal, a holder of Notes which is a broker-dealer
represents and agrees, consistent with certain interpretive letters issued by
the staff of the Division of Corporation Finance of the Securities and
Exchange Commission to third parties, that (a) such Notes held by the broker-
dealer are held only as a nominee or (b) such Notes were acquired by such
broker-dealer for its own account as a result of market-making activities or
other trading activities and it will deliver a copy of this prospectus in
connection with any resale of Exchange Securities (provided that, by so
acknowledging and by delivering a prospectus, such broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act). Further, by tendering in the Exchange Offer, each holder that
may be deemed an "affiliate" (as defined under Rule 405 of the Securities Act)
of the Borrower will represent to the Borrower that such holder understands
and acknowledges that the Exchange Notes may not be offered for resale, resold
or otherwise transferred by that holder without registration under the
Securities Act or an exemption therefrom.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
  As a result of the making of the Exchange Offer, the Borrower will have
fulfilled one of its obligations under the Registration Rights Agreements, and
holders of Notes who do not tender their Notes will not have any further
registration rights under the Registration Rights Agreements or otherwise.
Accordingly, any holder of Notes that does not exchange that holder's Notes
for Exchange Notes will continue to hold the untendered Notes and will be
entitled to all the rights and limitations applicable thereto under the
applicable Indenture, except to the extent such rights or limitations that, by
their terms, terminate or cease to have further effectiveness as a result of
the Exchange Offer.
 
  The Notes that are not exchanged for Exchange Notes pursuant to the Exchange
Offer will remain restricted securities. Accordingly, such Notes may be resold
only (i) to the Borrower (upon redemption thereof or otherwise), (ii) pursuant
to an effective registration statement under the Securities Act, (iii) so long
as the Notes are eligible for resale pursuant to Rule 144A, to a qualified
institutional buyer within the meaning of Rule 144A under the Securities Act
in a transaction meeting the requirements of Rule 144A, (iv) outside the
United States to a foreign person pursuant to the exemption from the
registration requirements of the Securities Act provided by Regulation S
thereunder, (v) to an institutional accredited investor that, prior to such
transfer, furnishes to the Bank of New York, as Trustee, a signed letter
containing certain representations and agreements relating to the restrictions
on transfer of the Notes evidenced thereby (the form of which letter can be
obtained from such Trustee) or (vi) pursuant to another available exemption
from the registration requirements of the Securities Act, in each case in
accordance with any applicable securities laws of any state of the United
States.
 
  Accordingly, if any Notes are tendered and accepted in the Exchange Offer,
the trading market for the untendered Notes could be adversely affected.
 
OTHER
 
  Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Notes are urged to
consult their financial and tax advisors in making their own decision on what
action to take.
 
  The Borrower may in the future seek to acquire untendered Notes in open
market or privately negotiated transactions, through subsequent exchange
offers or otherwise. However, the Borrower has no present plans to acquire any
Notes that are not tendered in the Exchange Offer or to file a registration
statement to permit resales of any untendered Notes.

                       DESCRIPTION OF THE EXCHANGE NOTES
 
  Each tranche of the Exchange Notes will be issued as a separate series of
notes pursuant to the same Indenture governing the corresponding tranche of
Notes for which each such tranche of Exchange Notes was exchanged. The form
and the terms of the Exchange Notes and the Notes will be substantially
identical to each other (including with respect to principal amount, interest
rate, maturity and redemption rights), except that (i) the offering and sale
of the Exchange Notes has been registered under the Securities Act and,
therefore, the Exchange Notes shall not bear certain legends restricting the
transfer thereof and (ii) the holders of Exchange Notes will not be entitled
to further registration rights under the Registration Rights Agreements, which
rights will be satisfied when the Exchange Offer is consummated. Under the
terms of the Indentures, the covenants and events of default will apply
equally to the Exchange Notes and the Notes, and the Exchange Notes and the
Notes will be treated as one class for all actions to be taken by the holders
thereof and for determining their respective rights under the Indentures,
including, without limitation, amendments, waivers and redemptions. For
purposes of this "Description of Exchange Notes" section all references herein
to "Notes" shall be deemed to refer collectively to Notes and Exchange Notes,
all references to "Senior Subordinated Notes" shall be deemed to refer
collectively to Senior Subordinated Notes and Senior Subordinated Exchange
Notes, and all references herein to "Senior Subordinated Discount Notes" shall
be deemed to refer collectively to Senior Subordinated Discount Notes and
Senior Subordinated Discount Exchange Notes, unless in any such case the
context otherwise requires. The terms of the Notes include those set forth in
the Indentures and those made a part of the Indentures by reference to the
TIA.
 
  The following summary of certain provisions of the Indentures and the
Registration Rights Agreements does not purport to be complete and is subject
to, and is qualified in its entirety by reference to, the TIA, and to all of
the provisions of the Indentures and the Registration Rights Agreements,
including the definitions of certain terms therein and those terms made a part
of the Indentures by reference to the TIA, as in effect on the date of the
Indentures. The Notes are subject to all such terms, and holders of the Notes
are referred to the Indentures, a copy of which has been filed as an exhibit
to the Registration Statement of which this Prospectus is a part and is
available in the manner described under "Available Information." Certain
defined terms used primarily in this section are set forth below under "--
Certain Definitions." Unless otherwise indicated, references under this
caption to sections, "(S)" or articles are references to sections and articles
of the Indentures. References in this "Description of the Exchange Notes"
section to the "Borrower" mean only TCI Satellite Entertainment, Inc. or
PRIMESTAR, Inc., as the case may be, and not any of their respective
Subsidiaries.
 
  Upon any exchange of Notes for Exchange Notes pursuant to the Exchange
Offer, the Notes so exchanged shall be canceled and shall no longer be deemed
outstanding for any purpose. In no event shall the aggregate principal amount
of all Senior Subordinated Notes and Senior Subordinated Exchange Notes
outstanding exceed $200,000,000, and in no event shall the aggregate principal
amount at maturity of all Senior Subordinated Discount Notes and Senior
Subordinated Discount Exchange Notes outstanding exceed $275,000,000.
 
  If the Borrower does not consummate the Exchange Offer, or, in lieu thereof,
the Borrower does not file and cause to become effective a resale shelf
registration for the Notes within the time periods set forth herein,
additional interest will continue to accrue and be payable on the Notes either
temporarily or permanently. See "--Registration Rights; Exchange Offer."
 
  Transfers of Notes may be made only by presentation of the Notes, duly
endorsed, to the Trustee for registration of transfer on the Security Register
maintained by the Trustee for such purposes. Unless and until a Note is duly
presented to the Trustee for registration of transfer, the Borrower and the
Trustee may treat the Person in whose name such Note is registered on the
Security Register as the sole owner thereof for all purposes under the
applicable Indenture, notwithstanding any notice to the contrary.
 
GENERAL
 
  The Notes will be issued only in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000 the Borrower will
appoint The Bank of New York to serve as registrar and paying agent
 
                                      52
<PAGE>
 
under the Indentures at its offices at 101 Barclay Street, New York, New York
10286. No service charge will be made for any registration of transfer or
exchange of the Notes, except for any tax or other governmental charge that
may be imposed in connection therewith.
 
RANKING
 
  The Notes will rank junior to, and be subordinated in right of payment to,
all existing and future Senior Indebtedness of the Borrower, pari passu in
right of payment with all senior subordinated Indebtedness of the Borrower and
senior in right of payment to all Subordinated Indebtedness of the Borrower.
As of December 31, 1997, the Borrower had approximately $48,000,000 of Senior
Indebtedness outstanding, which consisted of borrowings outstanding under the
Bank Credit Facility. The Bank Credit Facility is guaranteed by all the direct
and indirect Subsidiaries of the Borrower, other than Tempo, and, therefore,
the Notes are structurally subordinated to all obligations under the Bank
Credit Facility. the Borrower will not be permitted to incur any debt that is
subordinated in right of payment to any Senior Indebtedness of the Borrower
and senior in right of payment to the Notes.
 
  The Notes will not be entitled to any security and will not be entitled to
the benefit of any guarantees, except under the circumstances described under
"--Certain Covenants; Limitation on Indebtedness."
 
MATURITY, INTEREST AND PRINCIPAL OF THE SENIOR SUBORDINATED NOTES
 
  The Senior Subordinated Notes will be limited to $200,000,000 aggregate
principal amount (the "Senior Subordinated Aggregate Principal Amount") and
will mature on February 15, 2007. Cash interest on the Senior Subordinated
Notes accrues at a rate of 10 7/8% per annum and is payable semi-annually in
arrears on each February 15 and August 15, to the holders of record at the
close of business on February 1 and August 1, respectively, immediately
preceding such interest payment date. Cash interest on the Senior Subordinated
Exchange Notes will be payable semi-annually in arrears commencing August 15,
1998 and each February 15 and August 15 thereafter until maturity, to the
holders of record at the close of business on February 1 and August 1,
respectively immediately preceding such interest payment date. Cash interest
will accrue from the most recent interest payment date to which interest has
been paid or, if no interest has been paid, from February 20, 1997. Interest
will be computed on the basis of a 360-day year of twelve 30-day months.
 
MATURITY, INTEREST AND PRINCIPAL OF THE SENIOR SUBORDINATED DISCOUNT NOTES
 
  The Senior Subordinated Discount Notes will be limited to $275,000,000
aggregate principal amount at maturity (the "Senior Subordinated Discount
Aggregate Principal Amount") and will mature on February 15, 2007. The Senior
Subordinated Discount Notes were issued at a discount to their aggregate
principal amount at maturity and generated gross proceeds to the Borrower of
approximately $152,061,250. Based on the issue price thereof, the yield to
maturity of the Senior Subordinated Discount Notes and all Senior Subordinated
Discount Exchange Notes issued in exchange therefor is 12 1/4% (computed on a
semi-annual bond equivalent basis), calculated from February 20, 1997. See
"Certain Federal Income Tax Considerations."
 
  Cash interest will not accrue or be payable on the Senior Subordinated
Discount Notes prior to February 15, 2002. Thereafter, cash interest will
accrue at a rate of 12 1/4% per annum and will be payable semi-annually in
arrears on each February 15 and August 15, commencing on August 15, 2002, to
the holders of record at the close of business on the February 1 and August 1,
respectively, immediately preceding such interest payment date; provided,
however, that at any time prior to February 15, 2002, the Borrower may elect
(the "Cash Interest Election") on any interest payment date (the date of such
Cash Interest Election, the "Cash Interest Election Date") to commence the
accrual of cash interest from and after the Cash Interest Election Date, in
which case the principal amount at maturity of each Senior Subordinated
Discount Note will on such interest payment date be reduced to the Accreted
Value of such note as of such interest payment date, and cash interest
(accruing at a rate of 12 1/4% per annum from the Cash Interest Election Date)
shall be payable with respect to such Senior Subordinated Discount Note on
each interest payment date thereafter. Cash interest will accrue from the most
recent interest payment date to which interest has been paid or, if no
interest has been paid, from February 15,
 
                                      53
<PAGE>
 
2002 or the Cash Interest Election Date, if earlier. Interest will be computed
on the basis of a 360-day year of twelve 30-day months.
 
OPTIONAL REDEMPTION
 
  Optional Redemption of Senior Subordinated Notes. The Senior Subordinated
Notes will be redeemable at the option of the Borrower, in whole or in part,
at any time on or after February 15, 2002, at the redemption prices (expressed
as a percentage of principal amount) set forth below, plus accrued and unpaid
interest thereon, if any, to the redemption date, if redeemed during the 12-

  In addition, prior to February 15, 2000, the Borrower may, other than in any
circumstance resulting in a Change of Control, redeem up to 35% of the Senior
Subordinated Aggregate Principal Amount at a redemption price equal to
110.875% of the principal amount of the Senior Subordinated Notes so redeemed,
plus accrued and unpaid interest thereon, if any, to the redemption date with
the net cash proceeds of (a) one or more Public Equity Offerings of common

million in the aggregate; provided, however, that Senior Subordinated Notes in
an aggregate principal amount not less than the 65% of the Senior Subordinated
Aggregate Principal Amount would remain outstanding immediately after giving
effect to any such redemption (excluding any Senior Subordinated Notes owned
by the Borrower or any of its Affiliates). Notice of any such redemption must
be given within 60 days after the date of the last Public Equity Offering or

Investors resulting in gross cash proceeds to the Borrower, when aggregated
with all prior Public Equity Offerings and sales of Qualified Equity Interests
of the Borrower to Strategic Equity Investors, of at least $100.0 million.

  In addition, prior to February 15, 2000, the Borrower may, other than in any
circumstance resulting in a Change of Control, redeem up to 35% of the
originally issued principal amount at maturity of the Senior Subordinated
Discount Notes at a redemption price equal to 112.250% of the Accreted Value
of the Senior Subordinated Discount Notes so redeemed at the redemption date
or, if a Cash Interest Election has been made, 112.250% of the principal
amount at maturity of the Senior Subordinated Discount Notes so redeemed, plus
accrued and unpaid interest thereon, if any, to the redemption date, with the
net cash proceeds of (a) one or more Public Equity Offerings of common equity
of the Borrower or (b) a sale or series of related sales of Qualified Equity
Interests of the Borrower to Strategic Equity Investors, in any such case
resulting in gross cash proceeds
 
                                      54
<PAGE>
 
to the Borrower of at least $100.0 million in the aggregate; provided,
however, that at least 65% of the originally issued principal amount at
maturity of the Senior Subordinated Discount Notes would remain outstanding
immediately after giving effect to any such redemption (excluding any Senior
Subordinated Discount Notes owned by the Borrower or any of its Affiliates).
Notice of any such redemption must be given within 60 days after the date of
the last Public Equity Offering or sale of Qualified Equity Interests of the
Borrower to Strategic Equity Investors resulting in gross cash proceeds to the
Borrower, when aggregated with all prior Public Equity Offerings and sales of
Qualified Equity Interests of the Borrower to Strategic Equity Investors, of
at least $100.0 million.
 
SELECTION AND NOTICE OF REDEMPTION
 
  In the event that less than all of either tranche of the Notes are to be
redeemed at any time pursuant to an optional redemption, selection of such
Notes for redemption will be made by the applicable Trustee in compliance with
the requirements of the principal national securities exchange, if any, on
which such Notes are listed or, if such Notes are not then listed on a
national securities exchange, on a pro rata basis, by lot or by such method as
the applicable Trustee shall deem fair and appropriate; provided, however,
that no Notes of a principal amount or principal amount at maturity, as the
case may be, of $1,000 or less shall be redeemed in part; provided, further,
however, that if a partial redemption is made with the proceeds of a Public
Equity Offering or sale or series of related sales of Qualified Equity
Interests of the Borrower to Strategic Equity Investors, selection of the
Notes of either tranche or portions thereof for redemption shall be made by
the applicable Trustee only on a pro rata basis or on as nearly a pro rata
basis as is practicable (subject to the procedures of The Depository Trust
Company), unless such method is otherwise prohibited. Notice of redemption
shall be mailed by first-class mail at least 30 but not more than 60 days
before the redemption date to each holder of Notes of the tranche to be
redeemed at its registered address. If any Note is to be redeemed in part
only, the notice of redemption that relates to such Note shall state the
portion of the principal amount or principal amount at maturity, as the case
may be, thereof to be redeemed. A new Note of the applicable tranche in a
principal amount or principal amount at maturity, as the case may be, equal to
the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original Note. On and after the redemption
date, interest will cease to accrue on Notes or portions thereof called for
redemption as long as the Borrower has deposited with the applicable paying
agent for the Notes funds in satisfaction of the applicable redemption price
pursuant to the applicable Indenture.
 
SUBORDINATION OF THE NOTES
 
  The payment of the principal of, premium, if any, and interest on the Notes
is subordinated in right of payment, to the extent and in the manner provided
in each Indenture, to the prior payment in full in cash of all Senior
Indebtedness.
 
  Upon any payment or distribution of assets or securities of the Borrower of
any kind or character, whether in cash, property or securities (excluding any
payment or distribution of Permitted Junior Securities), upon any dissolution
or winding-up or liquidation or reorganization of the Borrower, whether
voluntary or involuntary or in bankruptcy, insolvency, receivership or other
proceedings, all Senior Indebtedness shall first be paid in full in cash
before the holders of the Notes or the applicable Trustee on behalf of such
holders shall be entitled to receive any payment by the Borrower of the
principal of, premium, if any, or interest on the Notes, or any payment by the
Borrower to acquire any of the Notes for cash, property or securities, or any
distribution by the Borrower with respect to the Notes of any cash, property
or securities (excluding any payment or distribution of Permitted Junior
Securities). Before any payment may be made by, or on behalf of, the Borrower
of the principal of, premium, if any, or interest on the Notes upon any such
dissolution or winding-up or total liquidation or reorganization, any payment
or distribution of assets or securities of the Borrower of any kind or
character, whether in cash, property or securities (excluding any payment or
distribution of Permitted Junior Securities), to which the holders of the
Notes or the applicable Trustee on their behalf would be entitled, but for the
subordination provisions of the applicable Indenture, shall be made by the
Borrower or by any receiver, trustee in bankruptcy, liquidation trustee, agent
or other Person making such payment or distribution, directly to the holders
of the Senior Indebtedness (pro rata to such holders on the basis of the
respective amounts of Senior
 
                                      55
<PAGE>
 
Indebtedness held by such holders) or their representatives or to the trustee
or trustees or agent or agents under any agreement or indenture pursuant to
which any of such Senior Indebtedness may have been issued, as their
respective interests may appear, to the extent necessary to pay all such
Senior Indebtedness in full in cash after giving effect to any prior or
concurrent payment, distribution or provision therefor to or for the holders
of such Senior Indebtedness.
 
  No direct or indirect payment (excluding any payment or distribution of
Permitted Junior Securities) by or on behalf of the Borrower of principal of,
premium, if any, or interest on the Notes, whether pursuant to the terms of
the Notes, upon acceleration or otherwise, will be made if, at the time of
such payment, there exists an event of default in the payment of all or any
portion of the obligations on any Designated Senior Indebtedness, whether at
maturity, on account of mandatory redemption or prepayment, acceleration or
otherwise, and such event of default shall not have been cured or waived or
the benefits of this sentence waived by or on behalf of the holders of such
Designated Senior Indebtedness. In addition, during the continuance of any
non-payment event of default with respect to any Designated Senior
Indebtedness pursuant to which the maturity thereof may be immediately
accelerated, and upon receipt by the applicable Trustee of written notice (a
"Payment Blockage Notice") from the holder or holders of such Designated
Senior Indebtedness or the trustee or agent acting on behalf of such
Designated Senior Indebtedness, then, unless and until such event of default
has been cured or waived or has ceased to exist or such Designated Senior
Indebtedness has been discharged or repaid in full in cash or the benefits of
these provisions have been waived by the holders of such Designated Senior
Indebtedness, no direct or indirect payment (excluding any payment or
distribution of Permitted Junior Securities) will be made by or on behalf of
the Borrower of principal of, premium, if any, or interest on the Notes,
except from those funds held in trust for the benefit of holders of any Notes
pursuant to the procedures set forth under "--Satisfaction and Discharge of
Indentures; Defeasance" below, to such holders, during a period (a "Payment
Blockage Period") commencing on the date of receipt of such notice by the
applicable Trustee and ending 179 days thereafter. Notwithstanding anything in
the subordination provisions of the Indentures or the Notes to the contrary,
(x) in no event will a Payment Blockage Period extend beyond 179 days from the
date the Payment Blockage Notice in respect thereof was given, (y) there shall
be a period of at least 181 consecutive days in each 360-day period when no
Payment Blockage Period is in effect and (z) not more than one Payment
Blockage Period may be commenced with respect to the Notes during any period
of 360 consecutive days. No event of default that existed or was continuing on
the date of commencement of any Payment Blockage Period with respect to the
Designated Senior Indebtedness initiating such Payment Blockage Period (to the
extent the holder of Designated Senior Indebtedness, or trustee or agent,
giving notice commencing such Payment Blockage Period had knowledge of such
existing or continuing event of default) may be, or be made, the basis for the
commencement of any other Payment Blockage Period by the holder or holders of
such Designated Senior Indebtedness or the trustee or agent acting on behalf
of such Designated Senior Indebtedness, whether or not within a period of 360
consecutive days, unless such event of default has been cured or waived for a
period of not less than 90 consecutive days.
 
  The failure to make any payment or distribution for or on account of the
Notes by reason of the provisions of the Indentures described under this
"Subordination of the Notes" heading will not be construed as preventing the
occurrence of any Event of Default in respect of either tranche of the Notes.
See "--Events of Default" below.
 
  By reason of the subordination provisions described above, in the event of
insolvency of the Borrower, funds which would otherwise be payable to holders
of the Notes will be paid to the holders of Senior Indebtedness to the extent
necessary to pay the Senior Indebtedness in full in cash, and the Borrower may
be unable to fully meet its obligations with respect to the Notes.
 
  As of December 31, 1997, the Borrower had approximately $79,949,000 of
Senior Indebtedness outstanding, of which $48,000 represented borrowings under
the Bank Credit Facility. Subject to the restrictions set forth in the
Indentures, in the future, TSAT may issue additional Senior Indebtedness to
refinance existing Indebtedness or for other corporate purposes.

OFFER TO PURCHASE UPON CHANGE OF CONTROL
 
  Following the occurrence of a Change of Control as defined in the Indentures
(the date of such occurrence being the "Change of Control Date"), the Borrower
shall notify the holders of the Notes of such occurrence in the manner
prescribed by the Indentures and shall, within 20 days after the Change of
Control Date, make an Offer to Purchase all Notes of each tranche then
outstanding at a purchase price in cash equal to (x) with respect to the
Senior Subordinated Notes, 101% of the aggregate principal amount thereof,
plus accrued and unpaid interest thereon, if any, to the Purchase Date and (y)
with respect to the Senior Subordinated Discount Notes, 101% of the Accreted
Value on the Purchase Date, unless the Purchase Date is on or after the
earlier to occur of February 15, 2002 and the Cash Interest Election Date, in
which case such purchase price shall be equal to 101% of the aggregate
principal amount at maturity thereof, plus accrued and unpaid interest
thereon, if any, to the Purchase Date. The Borrower's obligations may be
satisfied if a third party makes the Offer to Purchase in the manner, at the
times and otherwise in compliance with the requirements of the Indentures
applicable to an Offer to Purchase made by the Borrower and purchases all
Notes validly tendered and not withdrawn under such Offer to Purchase.
 
  If a Change of Control occurs which also constitutes an event of default
under the Bank Credit Facility, the lenders under the Bank Credit Facility
would be entitled to exercise the remedies available to a secured lender under
applicable law and pursuant to the terms of the Bank Credit Facility.
Accordingly, any claims of such lenders with respect to the assets of the
Borrower will be prior to any claim of the holders of the Notes with respect
to such assets.
 
  If an Offer to Purchase is made, there can be no assurance that the Borrower
will have available funds sufficient to pay for all of the Notes that might be
tendered by holders of Notes seeking to accept the Offer to Purchase. If the
Borrower fails to repurchase all of the Notes tendered for purchase upon the
occurrence of a Change of Control, such failure will constitute an Event of
Default under the applicable Indenture. See "--Events of Default" below.
 
  If the Borrower makes an Offer to Purchase, the Borrower will comply with
all applicable tender offer laws and regulations, including, to the extent
applicable, Section 14(e) and Rule 14e-1 under the Exchange Act, and any other
applicable Federal or state securities laws and regulations and any applicable
requirements of any securities exchange on which the Notes are listed, and any
violation of the provisions of the Indentures relating to such Offer to
Purchase occurring as a result of such compliance shall not be deemed an Event
of Default or an event that, with the passing of time or giving of notice, or
both, would constitute an Event of Default.
 
  Except as described above with respect to a Change of Control, the
Indentures do not contain provisions that permit the holders of the Notes to
require that the Borrower repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar transaction.
 
  The Restructuring Transaction, as currently contemplated, would not
constitute a Change of Control.

  Restricted Subsidiary is the survivor) as a result of or in connection with
  such Investment) (such payments or any other actions (other than the
  exceptions thereto) described in (i), (ii), (iii) and (iv) collectively,
  "Restricted Payments"), unless
 
      (a) no Default or Event of Default shall have occurred and be
    continuing at the time or after giving effect to such Restricted
    Payment;
 
      (b) immediately after giving effect to such Restricted Payment, the
    Borrower would be able to Incur $1.00 of Indebtedness (other than
    Permitted Indebtedness) under the Debt to Operating Cash Flow Ratio of
    the first paragraph of "--Limitation on Indebtedness" below; and
 
      (c) immediately after giving effect to such Restricted Payment, the
    aggregate amount of all Restricted Payments declared or made on or
    after the Issue Date does not exceed an amount equal to the sum of (1)
    the difference between (x) the Cumulative Operating Cash Flow
    determined at the time of such Restricted Payment and (y) 150% of
    cumulative Consolidated Interest Expense of the Borrower determined for
    the period commencing on the Issue Date and ending on the last day of
    the most recent fiscal quarter immediately preceding the date of such

    using funds borrowed from the Borrower or any Restricted Subsidiary
    until and to the extent such borrowing is repaid), plus (3) the
    principal amount (or accrued or accreted amount, if less) of any
    Indebtedness of the Borrower or any Restricted Subsidiary Incurred
    after the Issue Date which has been converted into or exchanged for
    Qualified Equity Interests of the Borrower, plus (4) in the case of the
    disposition or repayment of any Investment constituting a Restricted
    Payment made after the Issue Date, an amount (to the extent not
    included in the computation of Cumulative Operating Cash Flow) equal to
    the lesser of: (i) the return of capital with respect to such
    Investment and (ii) the amount of such Investment which was treated as
    a Restricted Payment, in either case, less the cost of the disposition
    of such Investment and net of taxes, plus (5) so long as the
    Designation thereof was treated as a Restricted Payment made after the
    Issue Date, with respect to any Unrestricted Subsidiary that has been
    redesignated as a Restricted Subsidiary after the Issue Date in
    accordance with "--Designation of Unrestricted Subsidiaries;
    Designation of Tempo as a Restricted Subsidiary" below, the Borrower's
    proportionate interest in an amount equal to the excess of (x) the
    total assets of such Subsidiary, valued on an aggregate basis at the
    lesser of book value and Fair Market Value, over (y) the total
    liabilities of such Subsidiary, determined in accordance with GAAP (and
    provided that such amount shall not in any case exceed the Designation
    Amount with respect to such Restricted Subsidiary upon its
    Designation), plus (6) (to the extent not included in the computation
    of Cumulative Operating Cash Flow) the amount of cash dividends or cash
    distributions (other than to pay taxes) received from any Unrestricted
    Subsidiary since the Issue Date, minus (7) the greater of (i) $0 and
    (ii) the Designation Amount (measured as of the date of Designation)

    designated as an Unrestricted Subsidiary after the Issue Date in
    accordance with "--Designation of Unrestricted Subsidiaries;
    Designation of Tempo as a Restricted Subsidiary" below. As presently
    contemplated, the Restructuring Transaction, pursuant to which the
    Borrower shall transfer substantially all of its assets to New
    PRIMESTAR and New PRIMESTAR shall assume, among other liabilities, the
    Exchange Notes (and any Notes outstanding), which assumption of such
    notes shall be evidenced by the execution by New PRIMESTAR of
    supplemental indentures governing the notes, would not constitute a
    default under the Indentures with respect to the foregoing provisions.

formal notice such payment or redemption would comply with the provisions of
the Indentures; (ii) the purchase, redemption, retirement or other acquisition
of any Equity Interests of the Borrower in exchange for, or out of the net

from clause (c)(2) of the preceding paragraph (and were not included therein
at any time); (iii) the purchase, redemption, retirement, defeasance or other
acquisition of Subordinated Indebtedness, or any other payment thereon, made

Qualified Equity Interests of the Borrower; provided, however, that any such
net cash proceeds and the value of any Equity Interests issued in exchange for
Subordinated Indebtedness are excluded from clauses (c)(2) and (c)(3) of the

such Unrestricted Subsidiary, times (y) such Unrestricted Subsidiary's share
of satellite construction and financing costs; provided, however, that the
funds used for such Investments shall be derived solely from Consolidated
Operating Cash Flow since the Issue Date of the High Power Satellite
Transmission Subsidiary (so long as such Consolidated Operating Cash Flow of
the High Power Satellite Transmission Subsidiary shall not have been otherwise
expended); provided, however, that no such Investment pursuant to this clause
(x) shall be permitted to the extent that the Consolidated Operating Cash Flow
of the High Power Satellite Transmission Subsidiary to be utilized to effect
such Investment was included in the calculation of the Cumulative Operating
Cash Flow at any time prior to the making of such Investment; (xi) Investments
in any other Person engaged in the satellite, telecommunications,
entertainment, electronics or any related industry, not to exceed $50.0
million in the aggregate outstanding at any time; provided, however, that so
long as no Default or Event of Default shall have occurred and be continuing,
such amount shall be increased to a maximum of (I) $75.0 million in the

completed fiscal quarter of the Borrower after the Issue Date, the Borrower
shall have provided an Officers'
 
                                      59
<PAGE>
 
Certificate to the Trustees that the Borrower and the Restricted Subsidiaries
had as of such date in excess of 1.2 million subscribers or (II) $90.0 million
in the aggregate outstanding at any time if, as of the end of the most
recently completed fiscal quarter of the Borrower after the Issue Date, the
Borrower shall have provided an Officers' Certificate to the Trustees that the
Borrower and the Restricted Subsidiaries had as of such date in excess of 1.6
million subscribers; (xii) the payment of dividends in any period (I) on
preferred stock of the Borrower issued in connection with any C-Band
Investment in a C-Band Entity, but only up to the amount of cash dividends
("C-Band Dividends") received by the Borrower from such C-Band Entity in the
same period (to the extent that such cash dividends have not otherwise been
expended by the Borrower) or (II) issued in connection with any C-Band
Investment which results in any C-Band Entity becoming a Restricted Subsidiary
(such Restricted Subsidiary, a "Restricted C-Band Subsidiary"), but only up to
the amount of Consolidated Operating Cash Flow received as cash dividends by
the Borrower from the Restricted C-Band Subsidiaries in the same period (to
the extent that such cash dividends have not otherwise been expended by the
Borrower); provided, however, that no such dividends pursuant to this clause
(xii) shall be permitted to the extent that C-Band Dividends or the
Consolidated Operating Cash Flow of any Restricted C-Band Subsidiary to be
utilized to effect any such dividends was included in the calculation of
Cumulative Operating Cash Flow at any time prior to the payment of such
dividends; or (xiii) the repurchase of Equity Interests of the Borrower in an
amount not to exceed $10.0 million in the aggregate since the Issue Date;
provided, however, that in the case of each of clauses (ii), (iii), (iv), (v),
(vi), (vii), (x), (xi), (xii) and (xiii) no Default or Event of Default shall
have occurred and be continuing or would arise therefrom. For purposes of this
paragraph, any Investment made in any Person that subsequently becomes a
Restricted Subsidiary shall be deemed not to be outstanding so long as such
Person is a Restricted Subsidiary.
 
  For purposes of clause (x) of the preceding paragraph, in determining
Consolidated Operating Cash Flow of the High Power Satellite Transmission
Subsidiary, the definition of "Consolidated Operating Cash Flow" shall be
used, but references in such definition to the Borrower and the Restricted
Subsidiaries shall be deemed to refer to the High Power Satellite Transmission
Subsidiary and its Subsidiaries. The Borrower shall not calculate such
Consolidated Operating Cash Flow of the High Power Satellite Transmission
Subsidiary in any manner, or take any other action, that would result in such
Consolidated Operating Cash Flow being greater than what it would have been if
the High Power Satellite Transmission Subsidiary were an Affiliate of the
Borrower that was not a Restricted Subsidiary. For purposes of clause (xii) of
the preceding paragraph, in determining Consolidated Operating Cash Flow of
any Restricted C-Band Subsidiary, the definition of "Consolidated Operating
Cash Flow" shall be used, but references in such definition to the Borrower
and the Restricted Subsidiaries shall be deemed to refer to the Restricted C-
Band Subsidiary and its Subsidiaries. The Borrower shall not calculate such
Consolidated Operating Cash Flow of any Restricted C-Band Subsidiary in any
manner, or take any other action, that would result in such Consolidated
Operating Cash Flow being greater than what it would have been if such
Restricted C-Band Subsidiary were an Affiliate of the Borrower that was not a
Restricted Subsidiary.
 
  In determining the amount of Restricted Payments permissible under this
covenant, amounts expended pursuant to clauses (i), (viii), (x), and (xiii) of
the second preceding paragraph shall be included as Restricted Payments and
amounts expended pursuant to clauses (ii), (iii), (iv), (v), (vi), (vii),
(ix), (xi), and (xii) shall be excluded. The amount of any non-cash Restricted
Payment shall be deemed to be equal to the Fair Market Value thereof at the
date of the making of such Restricted Payment. If after the date of making any
Investment made in compliance with this covenant which is a guarantee, letter
of credit or other credit support any payments are made in respect of such
Investment, such payment shall not be deemed an additional Restricted Payment
to the extent the amount thereof, when added together with all other payments
made in respect of such Investment since the date such Investment was made, is
not in excess of the amount of the Investment.
 
  Limitation on Indebtedness. The Borrower shall not, and shall not cause or
permit any Restricted Subsidiary to, directly or indirectly, Incur any
Indebtedness (including Acquired Indebtedness) or issue any Disqualified
Equity Interests except for Permitted Indebtedness; provided, however, that
the Borrower may Incur Indebtedness and the Borrower may issue Disqualified
Equity Interests if, at the time of and immediately after giving pro forma
effect to such Incurrence of Indebtedness or issuance of Disqualified Equity
Interests and the
 
                                      60
<PAGE>
 
application of the proceeds therefrom, the Debt to Operating Cash Flow Ratio
would be less than or equal to (i) 7.25 to 1.0 if the date of such Incurrence
is on or before December 31, 1999, (ii) 6.50 to 1.0 if the date of such
Incurrence is after December 31, 1999 and on or prior to December 31, 2001 and
(iii) 5.75 to 1.0 if the date of such Incurrence is after December 31, 2001.
 
  The foregoing limitations will not apply to the Incurrence by the Borrower
(or any Restricted Subsidiary with respect to clauses (b), (d), (e), (g), (i),
(j), (l) and (m) below of this paragraph) of any of the following
(collectively, "Permitted Indebtedness"), each of which shall be given
independent effect:
 
    (a) Indebtedness under the Senior Subordinated Notes and the Senior
  Subordinated Discount Notes and the Indentures;
 
    (b) Existing Indebtedness;

  amount at any one time outstanding not to exceed the sum of (A) $750.0
  million, which amount shall be reduced by (x) any permanent reduction of
  commitments thereunder and (y) any other repayment accompanied by a
  permanent reduction of commitments thereunder (other than in connection
  with any refinancing thereof where the aggregate principal amount
  outstanding and commitments thereunder immediately prior thereto are not
  greater than such amounts immediately thereafter) and increased by any
  increase in the aggregate commitments under the Bank Credit Facility agreed
  to in connection with the occurrence of a Replacement Satellite Event (as
  defined in the Bank Credit Facility as in effect on the Issue Date)
  thereunder (provided that such increase shall not be effective for purposes
  of this paragraph (a) until (x) the successful launch and commencement of
  operations of a permanent substitute satellite to GE-2 pursuant to a
  procedure of acceptance substantially similar to the procedure regarding
  acceptance of GE-2 or (y) the successful implementation, as certified by
  the Borrower to the Trustees, of a plan of continued operation of the
  PRIMESTAR(R) business agreed to in writing by the Borrower and the
  arranging agents under the Bank Credit Facility, plus (B) any amounts
  outstanding under the Bank Credit Facility that utilize subparagraph (o) of
  this paragraph of this covenant;

  subordinated in right of payment to the payment and performance of the
  Borrower's obligations under any Senior Indebtedness, the Indentures and
  the Notes (or pledged to secure any Senior Indebtedness); provided,
  however, that an Incurrence of Indebtedness that is not permitted by this
  clause (d) shall be deemed to have occurred upon (i) any sale or other
  disposition of any Indebtedness of the Borrower or any Restricted
  Subsidiary referred to in this clause (d) to a Person (other than the
  Borrower or any Restricted Subsidiary); (ii) any sale or other disposition
  of Equity Interests of any Restricted Subsidiary which holds Indebtedness
  of the Borrower or another Restricted Subsidiary such that such Restricted
  Subsidiary ceases to be a Restricted Subsidiary or (iii) the designation of
  a Restricted Subsidiary which holds Indebtedness of the Borrower or any
  other Restricted Subsidiary as an Unrestricted Subsidiary;
 
    (e) guarantees by any Restricted Subsidiary of Senior Indebtedness of the
  Borrower; provided, however, that if any such guarantee shall be Incurred
  in respect of any Senior Indebtedness of the Borrower which has
  registration rights (including the requirement to effect an exchange offer
  registered under the Securities Act) or which is registered under the
  Securities Act, such Restricted Subsidiary shall guarantee the Notes on a
  senior subordinated basis as provided in the Indentures;
 
    (f) Interest Rate Protection Obligations of the Borrower relating to
  Indebtedness of the Borrower (which Indebtedness (i) bears interest at
  fluctuating interest rates and (ii) is otherwise permitted to be Incurred
  under this covenant); provided, however, that the notional principal amount
  of such Interest Rate Protection Obligations does not exceed the principal
  amount of the Indebtedness to which such Interest Rate Protection
  Obligations relate;
 
    (g) Purchase Money Indebtedness and Capitalized Lease Obligations which
  do not exceed $35.0 million in the aggregate at any one time outstanding;

    (h) Indebtedness or Disqualified Equity Interests to the extent
  representing a replacement, renewal, refinancing or extension
  (collectively, a "refinancing") of outstanding Indebtedness or Disqualified
  Equity Interests Incurred in compliance with the Debt to Operating Cash
  Flow Ratio of the first paragraph of this covenant or clause (a), (b), (i),
  (j), (k), (l) or (m) of this paragraph of this covenant; provided, however,
  that (i) any such refinancing shall not exceed the sum of the principal
  amount (or, if such Indebtedness or Disqualified Equity Interests provide
  for a lesser amount to be due and payable upon a declaration of
  acceleration thereof at the time of such refinancing, an amount no greater
  than such lesser amount) of the Indebtedness or Disqualified Equity
  Interests being refinanced, plus the amount of accrued interest or
  dividends thereon, plus the amount of any reasonably determined prepayment
  premium necessary to accomplish such refinancing and such reasonable fees
  and expenses incurred in connection therewith, (ii) Indebtedness
  representing a refinancing of Indebtedness other than Senior Indebtedness
  shall have a Weighted Average Life to Maturity equal to or greater than the
  Weighted Average Life to Maturity of the Indebtedness being refinanced,

  with Indebtedness that is made pari passu with or subordinate in right of
  payment to the Notes and Subordinated Indebtedness or Disqualified Equity
  Interests may only be refinanced with Subordinated Indebtedness or
  Disqualified Equity Interests; (iv) no Restricted Subsidiary may Incur
  Indebtedness to refinance Indebtedness of the Borrower; and (v) with
  respect to any refinancing of Indebtedness Incurred pursuant to clauses
  (i), (j), (k) or (l) of this paragraph, such refinancing pursuant to this
  clause (h) also shall be deemed to be Incurred pursuant to clause (i), (j),
  (k) or (l), as the case may be, of this paragraph (for the avoidance of
  doubt, the result of which is that a refinancing does not create new debt
  Incurrence capacity under such clauses);
 
    (i) Indebtedness (including Acquired Indebtedness) not to exceed $180.0
  million in aggregate principal amount at any time outstanding, Incurred in
  connection with the acquisition by the Borrower or any Restricted
  Subsidiary of partnership interests in the Partnership not owned by the
  Borrower or any Restricted Subsidiary (including, without limitation, the
  acquisition of a Person (other than the Borrower or any Restricted
  Subsidiary) that owns partnership interests in the Partnership); provided,
  however, that (i) after giving effect to such purchase the Borrower or a
  Restricted Subsidiary owns such partnership interests and all right and
  title with respect thereto (including the income and profits therefrom);
  and (ii) any such Indebtedness Incurred by any Restricted Subsidiary shall
  only be permitted to be Incurred if it is Acquired Indebtedness and shall
  not be Incurred if such Acquired Indebtedness was Incurred in connection
  with, in contemplation of or with a view to such transaction;
 
    (j) Indebtedness (including Acquired Indebtedness) Incurred in connection
  with the acquisition of any Person distributing PRIMESTAR(R) television

  exceed $750.00 per subscriber acquired in such acquisition; (ii) such
  acquisition is effected through the Borrower or any Restricted Subsidiary
  or a Person that becomes a Restricted Subsidiary; and (iii) any such
  Indebtedness Incurred by any Restricted Subsidiary shall only be permitted
  to be Incurred if it is Acquired Indebtedness and shall not be Incurred if
  such Acquired Indebtedness was Incurred in connection with, in
  contemplation of or with a view to such transaction;
 
    (k) Indebtedness to fund purchases of inventory of integrated receiver
  decoders and other related subscriber equipment to be used in the business
  of the Borrower and the Restricted Subsidiaries not to exceed in the
  aggregate at any time outstanding the lesser of (x) 50% of the aggregate
  cost of such decoders and equipment and (y) $50.0 million;

  economic and Voting Equity Interests in the subject Person or is made to
  fund the acquisition of other satellite communications businesses by such
  Person in whom the C-Band Investment is being made (so long as such

  the satellite communications industry; (ii) such Related Acquisition is
  effected through the Borrower or any Restricted Subsidiary or a Person that
  becomes a Restricted Subsidiary; (iii) the aggregate amount of any such
  indebtedness Incurred to effect any C-Band Investments shall not exceed (x)

  time thereof of such Person in whom such C-Band Investment is being made
  and (y) $250.00 per subscriber acquired if such C-Band Investment is made
  to fund the acquisition by the Person in whom such C-Band Investment is
  being made of other satellite communications businesses; and (iv) any such
  Indebtedness Incurred by any Restricted Subsidiary shall only be permitted
  to be Incurred if it is Acquired Indebtedness and shall not be Incurred if

  contemplation of or with a view to such transaction;
 
    (m) Indebtedness under any guarantee, letter of credit or other credit
  support with respect to (x) any obligations of the Partnership under the
  Partnership Credit Agreement (or any refinancing thereof) to the extent
  such obligation was Incurred by the Partnership to finance any Tempo

  above, Indebtedness of the Borrower (including any Indebtedness under the
  Bank Credit Facility that utilizes this subparagraph (n)) having an

  outstanding; provided, however, that so long as no Default or Event of
  Default shall have occurred and be continuing, such amount shall be
  increased to a maximum of $100.0 million if, as of the end of the most
  recently completed fiscal quarter of the Borrower after the Issue Date, the
  Borrower shall have provided an Officers' Certificate to the Trustees that

such Person becomes a Restricted Subsidiary (or is merged into or consolidated
with the Borrower or any Restricted Subsidiary), whether or not such
Indebtedness was incurred in connection with, or in contemplation of, such
Person becoming a Restricted Subsidiary (or being merged into or consolidated
with the Borrower or any Restricted Subsidiary), shall be deemed Incurred at
the time any such Person becomes a Restricted Subsidiary or merges into or
consolidates with the Borrower or any Restricted Subsidiary; provided,
however, that any Indebtedness of any Unrestricted Subsidiary existing at the
time of its designation as a Restricted Subsidiary pursuant to the Required
Designation shall not be deemed Incurred at such time for purposes of the
covenant.
 
  If the Borrower Incurs any Indebtedness pursuant to the Debt to Operating
Cash Flow Ratio of the first paragraph of this covenant and included in the
calculation thereof the Consolidated Operating Cash Flow of the High Power
Satellite Transmission Subsidiary, C-Band Dividends or the Consolidated
Operating Cash Flow of any Restricted C-Band Subsidiary, then such
Indebtedness will be deemed to not have been Incurred in compliance with this
covenant (unless otherwise incurrable at such time under any of subparagraphs
(a)-(o) of the second paragraph of this covenant) if the Borrower or any
Restricted Subsidiary thereafter makes any Restricted Payment pursuant to
clause (x) or (xii) of the second paragraph of "--Limitation on Restricted
Payments" above and such Indebtedness could not have been Incurred at the time
of its Incurrence if any such Investment were made immediately prior to such
Incurrence.
 
  Limitation on Senior Subordinated Indebtedness. The Borrower shall not,
directly or indirectly, Incur any Indebtedness that by its terms would
expressly rank senior in right of payment to the Notes and expressly rank
subordinated in right of payment to any Senior Indebtedness.
 
  Limitations on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries. The Borrower shall not, and shall not cause or permit any
Restricted Subsidiary to, directly or indirectly, create or otherwise
 
                                      63

cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to (a) pay dividends or make any
other distributions to the Borrower or any other Restricted Subsidiary on its
Equity Interests or with respect to any other interest or participation in, or
measured by, its profits, or pay any Indebtedness owed to the Borrower or any
other Restricted Subsidiary, (b) make loans or advances to, or guarantee any
Indebtedness or other obligations of, the Borrower or any other Restricted
Subsidiary or (c) transfer any of its properties or assets to the Borrower or
any other Restricted Subsidiary, except for such encumbrances or restrictions
existing under or by reason of (i) the Bank Credit Facility, any Basic
Document or any other agreement of the Borrower or the Restricted Subsidiaries
outstanding on the Issue Date, in each case as in effect on the Issue Date,
and any amendments, restatements, renewals, replacements or refinancings
thereof; provided, however, that any such amendment, restatement, renewal,
replacement or refinancing is no more restrictive in the aggregate with
respect to such encumbrances or restrictions than those contained in the Bank
Credit Facility on the Issue Date; (ii) applicable law; (iii) any instrument
governing Indebtedness or Equity Interests of an Acquired Person acquired by
the Borrower or any Restricted Subsidiary as in effect at the time of such
acquisition (except to the extent such Indebtedness was incurred by such
Acquired Person in connection with, as a result of or in contemplation of such
acquisition); provided, however, that such encumbrances and restrictions are
not applicable to the Borrower or any Restricted Subsidiary, or the properties
or assets of the Borrower or any Restricted Subsidiary, other than the
Acquired Person; (iv) customary non-assignment provisions in leases entered
into in the ordinary course of business and consistent with past practices;
(v) Purchase Money Indebtedness for property acquired in the ordinary course
of business that only imposes encumbrances and restrictions on the property so
acquired; (vi) any agreement for the sale or disposition of the Equity
Interests or assets of any Restricted Subsidiary; provided, however, that such
encumbrances and restrictions described in this clause (vi) are only
applicable to such Restricted Subsidiary or assets, as applicable, and any
such sale or disposition is made in compliance with "--Disposition of Proceeds
of Asset Sales" below to the extent applicable thereto; (vii) refinancing
Indebtedness permitted under clause (h) of the second paragraph of "--
Limitation on Indebtedness" above; provided, however, that the encumbrances
and restrictions contained in the agreements governing such Indebtedness are
no more restrictive in the aggregate than those contained in the agreements
governing the Indebtedness being refinanced immediately prior to such
refinancing; (viii) the Notes Indentures; or (ix) any such customary
encumbrance or restriction existing under any other security agreement,
instrument or document hereafter in effect; provided, however, that the terms
and conditions of any such encumbrance or restriction are not more restrictive
than those contained in the Bank Credit Facility as in effect on the Issue
Date. Anything contained herein to the contrary notwithstanding, the Borrower
and its Subsidiaries shall in no event be prohibited or restrained from
granting, and causing to be effective, any lien or security interest securing
the obligations of the Borrower and the Restricted Subsidiaries under the Bank
Credit Facility.
 
  Designation of Unrestricted Subsidiaries; Designation of Tempo as a
Restricted Subsidiary. (a) Tempo and its Subsidiaries are initially designated
by TSAT as Unrestricted Subsidiaries as of the Issue Date. The Borrower may
designate after the Issue Date any other Subsidiary of the Borrower as an
"Unrestricted Subsidiary" under the Indentures (a "Designation") only if:
 
    (i) no Default or Event of Default shall have occurred and be continuing
  at the time of or after giving effect to such Designation;
 
    (ii) at the time of and after giving effect to such Designation, the
  Borrower could Incur $1.00 of additional Indebtedness (other than Permitted
  Indebtedness) under the Debt to Operating Cash Flow Ratio of the first
  paragraph of "--Limitation on Indebtedness" above; and
 
    (iii) The Borrower would be permitted to make an Investment (other than a
  Permitted Investment) at the time of Designation (assuming the
  effectiveness of such Designation) pursuant to the first paragraph of "--
  Limitation on Restricted Payments" above in an amount (the "Designation
  Amount") equal to the Fair Market Value of the Borrower's proportionate
  interest in the net worth of such Subsidiary on such date calculated in
  accordance with GAAP.
 
  Notwithstanding the above, no Subsidiary of the Borrower shall be designated
an Unrestricted Subsidiary which (i) holds the partnership interest in (or any
debt or equity interest in) the Partnership or distributes, directly
 
                                      64
<PAGE>
 
or indirectly, PRIMESTAR(R) television programming service or has any right,
title or interest in the revenue or profits in, or holds any Lien in respect
of, such partnership interests or such distribution or (ii) conducts, directly
or indirectly, the High Power Satellite Transmission Business or the business
of distributing high power DBS services to subscribers (or, if the proposed
Cable Plus strategy is implemented, the business of distributing the Cable
Plus service to cable system operators), or has any interest in any such
business or the right to receive the income or profits therefrom.
 
  Neither the Borrower nor any Restricted Subsidiary shall at any time (x)
provide credit support for, subject any of its property or assets (other than
the Equity Interests of any Unrestricted Subsidiary) to the satisfaction of,
or guarantee, any Indebtedness of any Unrestricted Subsidiary (including any
undertaking, agreement or instrument evidencing such Indebtedness), (y) be
directly or indirectly liable for any Indebtedness of any Unrestricted
Subsidiary or (z) be directly or indirectly liable for any Indebtedness which
provides that the holder thereof may (upon notice, lapse of time or both)
declare a default thereon or cause the payment thereof to be accelerated or
payable prior to its final scheduled maturity upon the occurrence of a default
with respect to any Indebtedness of any Unrestricted Subsidiary (other than
Tempo pursuant to the Bank Credit Facility), except, in the case of clause (x)
or (y), to the extent otherwise permitted under the terms of the Indentures,
including, without limitation, pursuant to "--Limitation on Restricted
Payments" above and "--Disposition of Proceeds of Asset Sales" below, and
except for any non-recourse guarantee given solely to support the pledge by
the Borrower or any Restricted Subsidiary of the Equity Interests of any
Unrestricted Subsidiary.
 
  (b) The Borrower shall designate (the "Required Designation") Tempo (or any
other Unrestricted Subsidiary which owns any Tempo Satellite or any right or
interest therein or holds a Lien in respect thereof or the right to receive
income or profits therefrom (Tempo or any such Unrestricted Subsidiary, the
"Satellite Subsidiary")) as a Restricted Subsidiary and revoke its designation
as an Unrestricted Subsidiary if as of the end of any complete fiscal quarter
of such Satellite Subsidiary after the Issue Date, the remainder of (x)
Consolidated Operating Cash Flow of such Satellite Subsidiary for the
immediately preceding complete fiscal quarter, minus (y) Consolidated Interest
Expense of such Satellite Subsidiary for such immediately preceding complete
fiscal quarter, minus (z) any scheduled principal payments in respect of
Indebtedness of such Satellite Subsidiary made during such immediately
preceding complete fiscal quarter is greater than $1.0 million. For purposes
of determining Consolidated Operating Cash Flow and Consolidated Interest
Expense of any Satellite Subsidiary pursuant to the immediately preceding
sentence, the definitions "Consolidated Operating Cash Flow" and "Consolidated
Interest Expense" shall be used, but references to the Borrower and the
Restricted Subsidiaries in such definitions shall be deemed to refer to the
relevant Satellite Subsidiary and its Subsidiaries.
 
  (c) The Borrower may revoke any Designation of a Subsidiary as an
Unrestricted Subsidiary (a "Revocation") if:
 
    (i) no Default or Event of Default shall have occurred and be continuing
  at the time of and after giving effect to such Revocation; and
 
    (ii) all Liens and Indebtedness of such Unrestricted Subsidiary
  outstanding immediately following such Revocation would, if Incurred at
  such time, have been permitted to be Incurred for all purposes of the
  Indentures; provided, however, that the foregoing shall not apply to the
  Required Designation.
 
  All Designations and Revocations must be evidenced by resolutions of the
Board of Directors of the Borrower, delivered to the Trustees certifying
compliance with the foregoing provisions.
 
  Limitation on Liens. The Borrower shall not, and shall not cause or permit
any Restricted Subsidiary to, directly or indirectly, Incur any Liens of any
kind against or upon any of their respective properties or assets now owned or
hereafter acquired, or any proceeds therefrom or any income or profits
therefrom, to secure any Indebtedness unless contemporaneously therewith
effective provision is made to secure the Notes equally and ratably with such
Indebtedness with a Lien on the same properties and assets securing
Indebtedness for so long as such Indebtedness is secured by such Lien, except
for (i) Liens securing any Senior Indebtedness or any guarantee of Senior
Indebtedness by any Restricted Subsidiary and (ii) Permitted Liens.
 
                                      65

  Disposition of Proceeds of Asset Sales. (a) the Borrower shall not, and
shall not cause or permit any Restricted Subsidiary to, directly or
indirectly, make any Asset Sale, unless (i) the Borrower or such Restricted
Subsidiary, as the case may be, receives consideration at the time of such
Asset Sale at least equal to the Fair Market Value of the assets sold or
otherwise disposed of and (ii) at least 85% of such consideration consists of
(A) cash or Cash Equivalents, (B) properties and capital assets to be used in
the same lines of business being conducted by the Borrower or any Restricted
Subsidiary at such time or (C) Equity Interests in one or more Persons which
thereby become Restricted Subsidiaries whose assets consist primarily of
properties and capital assets used in the same line of business being
conducted by the Borrower or any Restricted Subsidiary at such time. The
amount of any (i) Indebtedness (other than any Subordinated Indebtedness) of
the Borrower or any Restricted Subsidiary that is actually assumed by the
transferee in such Asset Sale and from which the Borrower and the Restricted
Subsidiaries are fully released shall be deemed to be cash for purposes of
determining the percentage of cash consideration received by the Borrower or
the Restricted Subsidiaries and (ii) notes or other similar obligations
received by the Borrower or the Restricted Subsidiaries from such transferee
that are immediately converted, sold or exchanged (or are converted, sold or
exchanged within thirty days of the related Asset Sale) by the Borrower or the
Restricted Subsidiaries into cash shall be deemed to be cash, in an amount
equal to the net cash proceeds realized upon such conversion, sale or exchange
for purposes of determining the percentage of cash consideration received by
the Borrower or the Restricted Subsidiaries.
 
  The Borrower or such Restricted Subsidiary, as the case may be, may (i)
apply the Net Cash Proceeds of any Asset Sale within 375 days of receipt
thereof to repay Senior Indebtedness and permanently reduce any related
commitment, (ii) commit in writing to acquire, construct or improve properties
and capital assets to be used in the same line of business being conducted by
the Borrower or any Restricted Subsidiary at such time and so apply such Net
Cash Proceeds within 375 days after the receipt thereof, or (iii) apply the
Net Cash proceeds of any Asset Sale within 375 days after receipt thereof to
the making of any Investment which is permitted to be made under "--Limitation
on Restricted Payments" above.
 
  To the extent all or part of the Net Cash Proceeds of any Asset Sale are not
applied within 375 days of such Asset Sale as described in clause (i), (ii) or
(iii) of the immediately preceding paragraph (such Net Cash Proceeds, the
"Unutilized Net Cash Proceeds"), the Borrower shall, within 20 days after such
375th day, make an Offer to Purchase all outstanding Notes of each tranche up
to a maximum principal amount (in the case of the Senior Subordinated Notes)
or Accreted Value (in the case of the Senior Subordinated Discount Notes)
(expressed as a multiple of $1,000) of Notes equal to the Securities Portion
of Unutilized Net Cash Proceeds, at a purchase price in cash equal to (x) with
respect to the Senior Subordinated Notes, 100% of the principal amount
thereof, plus accrued and unpaid interest thereon, if any, to the Purchase
Date, and (y) with respect to the Senior Subordinated Discount Notes, 100% of
the Accreted Value on the Purchase Date, unless the Purchase Date is on or
after the earlier to occur of February 15, 2002 and the Cash Interest Election
Date, in which case such purchase price shall be equal to 100% of the
principal amount at maturity thereof, plus accrued and unpaid interest
thereon, if any, to the Purchase Date; provided, however, that the Offer to
Purchase may be deferred until there are aggregate Unutilized Net Cash
Proceeds equal to or in excess of $15.0 million, at which time the entire
amount of such Unutilized Net Cash Proceeds, and not just the amount in excess
of $15.0 million, shall be applied as required pursuant to this paragraph.
 
  In the event that any other Indebtedness of the Borrower which ranks pari
passu with either tranche of the Notes (including the other tranche of the
Notes) (the "Other Indebtedness") requires that an offer to repurchase such
Indebtedness be made upon the consummation of any Asset Sale, the Borrower may
apply the Unutilized Net Cash Proceeds otherwise required to be applied to an
Offer to Purchase to offer to purchase such Other Indebtedness and to an Offer
to Purchase so long as the amount of such Unutilized Net Cash Proceeds applied
to repurchase the Notes of such tranche is not less than the Securities
Portion of Unutilized Net Cash Proceeds. With respect to any Unutilized Net
Cash Proceeds, the Borrower shall make the Offer to Purchase in respect
thereof at the same time under each Indenture and at the same time as the
analogous offer to purchase is made under any Other Indebtedness and the
Purchase Date in respect thereof shall be the same under each Indenture and
the same as the purchase date in respect thereof pursuant to any Other
Indebtedness.
 
                                      66
<PAGE>
 
  For purposes of this covenant, "Securities Portion of Unutilized Net Cash
Proceeds" means, with respect to either tranche of the Notes, the amount of
the Unutilized Net Cash Proceeds equal to the product of (x) the Unutilized
Net Cash Proceeds and (y) a fraction the numerator of which is the principal
amount or Accreted Value of all Notes of such tranche tendered pursuant to the
Offer to Purchase related to such Unutilized Net Cash Proceeds (the
"Securities Amount") and the denominator of which is the sum of the Securities
Amount and the lesser of the aggregate principal face amount or accreted value
as of the relevant purchase date of all Other Indebtedness tendered pursuant
to a concurrent offer to purchase such Other Indebtedness made at the time of
such Offer to Purchase.
 
  With respect to any Offer to Purchase effected pursuant to this covenant,
among the Senior Subordinated Notes, to the extent the aggregate principal
face amount of Senior Subordinated Notes tendered pursuant to such Offer to
Purchase exceeds the Securities Portion of Unutilized Net Cash Proceeds to be
applied to the repurchase thereof, such Notes shall be purchased pro rata
based on the aggregate principal face amount of such Senior Subordinated Notes
tendered by each holder, and, as among the Senior Subordinated Discount Notes,
to the extent that the Accreted Value as of the Purchase Date (or principal
amount at maturity after February 15, 2002 or, if a Cash Interest Election
shall have been made, the Cash Interest Election Date) of the Senior
Subordinated Discount Notes tendered pursuant to such Offer to Purchase
exceeds the Securities Portion of Unutilized Net Cash Proceeds with respect
thereto, such Notes shall be purchased pro rata based on the Accreted Value as
of the Purchase Date (or principal amount at maturity after February 15, 2002
or, if a Cash Interest Election shall have been made, the Cash Interest
Election Date) of such Senior Subordinated Discount Notes tendered by each
holder.
 
  In the event that the Borrower makes an Offer to Purchase the Notes, the
Borrower shall comply with any applicable securities laws and regulations,
including any applicable requirements of Section 14(e) of, and Rule 14e-1
under, the Exchange Act, and any violation of the provisions of the Indentures
relating to such Offer to Purchase occurring as a result of such compliance
shall not be deemed an Event of Default or an event that with the passing of
time or giving of notice, or both, would constitute an Event of Default.
 
  (b) Each holder shall be entitled to tender all or any portion of the Notes
owned by such holder pursuant to the Offer to Purchase, subject to the
requirement that any portion of a Note tendered must be tendered in an
integral multiple of $1,000 principal amount and subject to any proration
among tendering holders as described above.
 
  (c) So long as there are any amounts owed or due by the Borrower or any
Subsidiary to the Partnership under the Tempo Letter Agreements, or the
Borrower or any Restricted Subsidiary is directly or indirectly obligated,
contingently or otherwise, for any obligations under the Partnership Credit
Agreement (pursuant to any letter of credit, guarantee or other credit support
or otherwise), for purposes of the foregoing covenant, the sale or lease of
either or both of the Tempo Satellites (whether or not the Subsidiary owning
such Tempo Satellite is a Restricted Subsidiary), or any transponder thereon
or capacity thereof, to the Partnership or any other Person shall be
considered an Asset Sale unless (i) if such sale or lease is to the
Partnership of both Tempo Satellites, any balance due by the Borrower or any
Subsidiary to the Partnership under the Tempo Letter Agreements shall be
permanently extinguished and if such sale or lease is to the Partnership of
only one Tempo Satellite, then 100% of the net proceeds thereof are applied to
the balance due by the Borrower or any Subsidiary to the Partnership under the
Tempo Letter Agreements and (ii) if such sale or lease is to any other Person,
100% of the net proceeds thereof are applied to the balance due under the
Partnership Credit Agreement to the extent that the Borrower or any Restricted
Subsidiary has any letter of credit, guarantee or other credit support
outstanding in respect thereof and thereafter to the balance due by the
Borrower or any Subsidiary to the Partnership under the Tempo Letter
Agreements. The Borrower shall not and shall not cause or permit any
Subsidiary to enter into or suffer to exist any agreement, instrument,
encumbrance or restriction which would, directly or indirectly, limit,
prohibit or restrict the compliance by the Borrower and its Subsidiaries with
the foregoing sentence.
 
  (d) If the Borrower or any Restricted Subsidiary is engaged in the High
Power Satellite Transmission Business, the Borrower shall not and shall not
cause or permit any such High Power Satellite Transmission
 
                                      67
<PAGE>
 
Subsidiary to sell, convey, transfer, lease, assign, or otherwise encumber (i)
any Tempo Satellite (or any contract rights related to the construction,
launch or insurance thereof), (ii) any orbital slot owned by the Borrower or
any Subsidiary, (iii) the Equity Interests of any Subsidiary which owns any
Tempo Satellite or any orbital slot or any right, license, authorization or
permit with respect to any such orbital slot owned by such Subsidiary, or any
other interest in an orbital slot which may be sold or otherwise disposed of
in compliance with all applicable law (including the Communications Act and
the rules and regulations promulgated thereunder) or (iv) the income or
profits of any of the foregoing, unless in any such case, immediately after
such a transaction the Borrower or such High Power Satellite Transmission
Subsidiary has in place a binding agreement providing for dedicated satellite
capacity sufficient to serve its High Power Satellite Transmission Business at
least until the stated maturity of the Notes and files such agreement with the
Trustee together with an Officers' Certificate certifying that such agreement
meets the foregoing criteria.
 
  Amendments to Certain Agreements. The Borrower shall not, and shall not
cause or permit any Restricted Subsidiary to, amend, modify or waive, or
refrain from enforcing, any provision of the Basic Documents in any manner
adverse to the Borrower or any of its Subsidiaries or the holders of the Notes
in any material respect as determined by the Board of Directors of the
Borrower. This covenant shall not be construed to prohibit the Borrower or any
Restricted Subsidiary from terminating any of the Basic Documents, if a
majority of the disinterested members of the Board of Directors of the
Borrower shall determine that it is in the best interests of the Borrower to
do so.
 
  Tempo Satellites; Maintenance of Insurance. (a) Prior to 180 days following
the successful launch of any Tempo Satellite (which, in the case of Tempo DBS-
1, occurred on March 8, 1997), the Borrower shall not terminate the Satellite
Construction Agreement or amend, modify or refrain from enforcing any
provision thereof in any manner adverse to the Borrower or any of its
Subsidiaries or the holders of the Notes in any material respect, as
determined by the Board of Directors of the Borrower, and shall not amend,
modify or refrain from enforcing any provision thereof regarding the rights of
the Borrower under the Satellite Construction Agreement (if any) with respect
to any failure of any Tempo Satellite that may occur during the 180 day period
immediately thereafter.
 
  (b) If the Borrower or any Subsidiary is engaged in the High Power Satellite
Transmission Business, so long as a ground spare satellite of comparable
quality and capacity has not been completely constructed and available to be
launched and to provide (pursuant to a binding agreement, a copy of which has
been filed with the Trustees) sufficient capacity to the Borrower or the
Subsidiary conducting the High Power Satellite Transmission Business to
conduct such business on a competitive basis and service its subscribers, then
within 30 days after the acceptance of any Tempo Satellite by the Borrower or
any Subsidiary after completion of in-orbit testing by the builder thereof the
Borrower shall, or shall cause a Restricted Subsidiary to, obtain (to the
extent commercially available upon reasonable terms), and thereafter maintain,
In-Orbit Insurance with respect to the Tempo Satellite (or any permanent
replacement thereof) providing the servicing capacity with respect to such
High Power Satellite Transmission Business. The Borrower or such Restricted
Subsidiary shall be named as the insured under such In-Orbit Insurance
(provided that only a senior secured creditor of the Borrower or a Restricted
Subsidiary may also be designated as a named insured under such In-Orbit
Insurance).
 
  (c) In the event that the Borrower or any of its Subsidiaries receives any
damages or other amounts due under the Satellite Construction Agreement
(including, without limitation, the refund of the full purchase price of any
Tempo Satellite which has not been delivered pursuant to the terms thereof)
all such amounts shall be deemed to be Net Cash Proceeds from an Asset Sale
and the Borrower shall apply such proceeds as required by the second and third
full paragraphs under subparagraph (a) of "--Disposition of Proceeds of Asset
Sales" above, except as provided by subparagraph (c) thereof.
 
  Merger, Sale of Assets, etc. The Borrower shall not consolidate with or
merge with or into (whether or not the Borrower is the Surviving Person) any
other entity and the Borrower shall not and shall not cause or permit any
Restricted Subsidiary to, sell, convey, assign, transfer, lease or otherwise
dispose of all or substantially all of the Borrower's properties and assets
(determined on a consolidated basis for the Borrower
 
                                      68
<PAGE>
 
and the Restricted Subsidiaries) to any entity in a single transaction or
series of related transactions, unless: (i) either (x) the Borrower shall be
the Surviving Person or (y) the Surviving Person (if other than the Borrower)
shall be a corporation organized and validly existing under the laws of the
United States of America or any State thereof or the District of Columbia, and
shall, in any such case, expressly assume by a supplemental indenture, the due
and punctual payment of the principal of, premium, if any, and interest on all
the Notes and the performance and observance of every covenant of the
Indentures and the Registration Rights Agreements to be performed or observed
on the part of the Borrower; (ii) immediately thereafter, no Default or Event
of Default shall have occurred and be continuing; and (iii) immediately after
giving effect to any such transaction involving the Incurrence by the Borrower
or any Restricted Subsidiary, directly or indirectly, of additional
Indebtedness (and treating any Indebtedness not previously an obligation of
the Borrower or any Restricted Subsidiary in connection with or as a result of
such transaction as having been Incurred at the time of such transaction), the
Surviving Person could Incur, on a pro forma basis after giving effect to such
transaction as if it had occurred at the beginning of the latest fiscal
quarter for which consolidated financial statements of the Borrower are
available, at least $1.00 of additional Indebtedness (other than Permitted
Indebtedness) under the Debt to Operating Cash Flow Ratio of the first
paragraph of "--Limitation on Indebtedness" above; provided, however, that the
condition set forth in this clause (iii) need not be satisfied in connection
with the merger or consolidation with or into the Borrower or any Restricted
Subsidiary of any Person holding partnership interests in the Partnership if
(x) such merger or consolidation is effected for the purpose of acquiring the
partnership interests in the Partnership held by such Person (provided that
the amount of partnership interests in the Partnership held by such Person on
the date of such merger or consolidation is not less than the amount held by
such Person on the Issue Date otherwise than pursuant to the transfer of
partnership interests in the Partnership to another Person who has been or
simultaneously therewith will be merged or consolidated with or into the
Borrower or any Restricted Subsidiary or the dilution of such Person's
partnership interests in the Partnership solely due to its failure to pay
capital contributions required by the Partnership Agreement) and (y) in
connection with such acquisition of such partnership interests the Borrower or
a Restricted Subsidiary acquires all rights of such Person (and its
Affiliates) to distribute PRIMESTAR(R) programming services.
 
  For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all the properties and assets of one or more Restricted
Subsidiaries the Equity Interest of which constitutes all or substantially all
the properties and assets of the Borrower shall be deemed to be the transfer
of all or substantially all the properties and assets of the Borrower.
 
  In the event of any transaction (other than a lease) described in and
complying with the conditions listed in the second immediately preceding
paragraph in which the Borrower is not the Surviving Person and the Surviving
Person is to assume all the Obligations of the Borrower under the Notes, the
Notes Indentures and the Registration Rights Agreements pursuant to a
supplemental indenture, such Surviving Person shall succeed to, and be
substituted for, and may exercise every right and power of, the Borrower and
the Borrower shall be discharged from its Obligations under the Notes
Indentures and the Notes.
 
  Transactions with Affiliates. The Borrower shall not, and shall not cause or
permit any Restricted Subsidiary to, directly or indirectly, conduct any
business or enter into any transaction (or series of related transactions)
with or for the benefit of any of their respective Affiliates or any
beneficial holder of 10% or more of the Equity Interests of the Borrower or
any officer, director or employee of the Borrower or any Restricted Subsidiary
(each an "Affiliate Transaction"), unless such Affiliate Transaction is on
terms which are no less favorable to the Borrower or such Restricted
Subsidiary, as the case may be, than would be available in a comparable
transaction with an unaffiliated third party. If such Affiliate Transaction
(or series of related Affiliate Transactions) involves aggregate payments or
other consideration having a Fair Market Value in excess of $15.0 million, the
Borrower shall not, and shall not cause or permit any Restricted Subsidiary
to, enter into such Affiliate Transaction, unless a majority of the
disinterested members of the Board of Directors of the Borrower shall have
approved such Affiliate Transaction and determined that such Affiliate
Transaction complies with the foregoing provisions; provided, however, that if
such Affiliate Transaction is in the ordinary course of business consistent
with the past practice of any business of the Borrower or a Restricted
Subsidiary, including the High
 
                                      69
<PAGE>
 
Power Satellite Transmission Business, then there shall be no need to comply
with this sentence. In the event that the Borrower obtains a written opinion
from an Independent Financial Advisor (and files the same with the Trustees)
stating that the terms of an Affiliate Transaction are fair, from a financial
point of view, to the Borrower or the Restricted Subsidiary involved in such
Affiliate Transaction, as the case may be, such opinion will conclusively meet
the requirements of the first sentence of this paragraph and there shall be no
need to comply with the second sentence of this paragraph.
 
  Notwithstanding the foregoing, the restrictions set forth in this covenant
shall not apply to (i) transactions with or among the Borrower and any
Restricted Subsidiary or between or among Restricted Subsidiaries; (ii)
customary directors' fees, indemnification and similar arrangements,
consulting fees, employee salaries, bonuses or employment agreements,
compensation or employee benefit arrangements and incentive arrangements with
any officer, director or employee of the Borrower entered into in the ordinary
course of business (including customary benefits thereunder) and payments
under any indemnification arrangements permitted by applicable law; (iii) the
Basic Documents, each as in effect on the Issue Date, including any amendment
or extension thereof that does not otherwise violate any other covenant set
forth in the Indentures, and any transactions undertaken pursuant to any other
contractual obligations in existence on the Issue Date (as in effect on the
Issue Date); (iv) the issue and sale by the Borrower to its stockholders of
Qualified Equity Interests; (v) any Restricted Payments made in compliance
with "--Limitation on Restricted Payments" above; (vi) loans and advances to
officers, directors and employees of the Borrower and the Restricted
Subsidiaries for travel, entertainment, moving and other relocation expenses,

  Provision of Financial Information. Whether or not the Borrower is subject
to Section 13(a) or 15(d) of the Exchange Act, or any successor provision
thereto, the Borrower shall file with the SEC (if permitted by SEC practice
and applicable law and regulations) the annual reports, quarterly reports and
other documents which the Borrower would have been required to file with the
SEC pursuant to such Section 13(a) or 15(d) or any successor provision thereto
if the Borrower were so subject, such documents to be filed with the SEC on or
prior to the respective dates (the "Required Filing Dates") by which the
Borrower would have been required so to file such documents if the Borrower
were so subject. the Borrower shall also in any event (a) within 15 days of
each Required Filing Date (whether or not permitted or required to be filed
with the SEC) (i) transmit (or cause to be transmitted) by mail to all
holders, as their names and addresses appear in the Note Register, without
cost to such holders, and (ii) file with the Trustees, copies of the annual

notwithstanding the preceding sentence, filing such documents by the Borrower
with the SEC is not permitted by SEC practice or applicable law or
regulations, promptly upon written request supply copies of such documents to
any holder. In addition, for so long as any Notes remain outstanding, the
Borrower will furnish to the holders and to securities analysts and
prospective investors, upon their request, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act, and, to any
beneficial holder of Notes, if not obtainable from the SEC, information of the

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 the Indentures 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.
 
EVENTS OF DEFAULT
 
  The occurrence of any of the following will be defined as an "Events of
Default" under each Indenture: (a) failure to pay principal of (or premium, if
any, on) any Note when due (whether or not prohibited by the
 
                                      70
<PAGE>
 
provisions of the Indentures described under "--Subordination of the Notes"
above); (b) failure to pay any interest on any Note when due, continued for 30
days or more (whether or not prohibited by the provisions of the Indentures
described under "--Subordination of the Notes" above); (c) default in the
payment of principal of or interest on Notes required to be purchased pursuant
to any Offer to Purchase required by the Indentures when due and payable or
failure to pay on the Purchase Date the Purchase Price for any Note validly
tendered pursuant to any Offer to Purchase (whether or not prohibited by the
provisions of the Indentures described under "--Subordination of the Notes"
above); (d) failure to perform or comply with any of the provisions described
under "--Certain Covenants--Merger, Sale of Assets, etc." above; (e) failure
to perform any other covenant, warranty or agreement of the Borrower or the
Guarantors under the Indentures, or in the Notes continued for 30 days or more
after written notice to the Borrower by the applicable Trustee or holders of
at least 25% in aggregate principal face amount of the outstanding Senior
Subordinated Notes or holders of at least 25% of the aggregate principal
amount at maturity of the Senior Subordinated Discount Notes, as the case may
be, under the applicable Indenture; (f) default or defaults under the terms of
one or more instruments evidencing or securing Indebtedness of the Borrower or
any of its Significant Restricted Subsidiaries or, so long as the Borrower or
any Significant Restricted Subsidiary is a general partner thereof or is
(directly or indirectly) obligated in any way (contingently or otherwise) with
respect to its Indebtedness, the Partnership having an outstanding principal
amount of $15.0 million or more individually or in the aggregate that has
resulted in the acceleration of the payment of such Indebtedness or failure by
the Borrower or any of its Significant Restricted Subsidiaries or, so long as
the Borrower or any Significant Restricted Subsidiary is a general partner
thereof or is (directly or indirectly) obligated in any way (contingently or
otherwise) with respect to its Indebtedness, the Partnership to pay principal
when due at the stated maturity of any such Indebtedness; provided, however,
that it shall not be an Event of Default if such Indebtedness shall have been
repaid in full or such acceleration shall have been rescinded within 20 days;
(g) the rendering of a final judgment or judgments (not subject to appeal)
against the Borrower or any of its Significant Restricted Subsidiaries in an
amount of $15.0 million or more (net of any amounts covered by reputable and
creditworthy insurance companies) which remains undischarged or unstayed for a
period of 60 days after the date on which the right to appeal has expired; or
(h) certain events of bankruptcy, insolvency or reorganization affecting the
Borrower or any of its Significant Restricted Subsidiaries or, so long as the
Borrower or any Significant Restricted Subsidiary is a general partner thereof
or is (directly or indirectly) obligated in any way (contingently or
otherwise) with respect to its Indebtedness, the Partnership. Subject to the
provisions of the Indentures relating to the duties of the Trustees, in case
an Event of Default shall occur and be continuing, each Trustee will be under
no obligation to exercise any of its rights or powers under the Indenture to
which it is a party at the request or direction of any of the holders of Notes
issued thereunder, unless such holders shall have offered to such Trustee
reasonable indemnity. Subject to such provisions for the indemnification of
the applicable Trustee, the holders of a majority in aggregate principal face
amount of the outstanding Senior Subordinated Notes or the holders of a
majority in aggregate principal amount at maturity of the Senior Subordinated
Discount Notes, as the case may be, will have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
applicable Trustee, as the case may be, or exercising any trust or power
conferred on such Trustee.
 
  If an Event of Default with respect to the Notes (other than an Event of
Default with respect to the Borrower described in clause (h) of the preceding
paragraph) occurs and is continuing, the applicable Trustee or the holders of
at least 25% in aggregate principal face amount of the outstanding Senior
Subordinated Notes or the holders of at least 25% in aggregate principal
amount at maturity of the outstanding Senior Subordinated Discount Notes, as
the case may be, by notice in writing to the Borrower may declare the unpaid
principal of (and premium, if any) and accrued interest to the date of
acceleration on all the outstanding Senior Subordinated Notes and Senior
Subordinated Discount Notes, as the case may be, to be due and payable
immediately and, upon any such declaration, such principal amount (and
premium, if any) and accrued interest, notwithstanding anything contained in
the applicable Indenture or the Senior Subordinated Notes and Senior
Subordinated Discount Notes, as the case may be, to the contrary, but subject
to the provisions limiting payment described above under "--Subordination of
the Notes," will become immediately due and payable; provided, however, that
so long as the Bank Credit Facility shall be in full force and effect, if an
Event of Default shall have occurred and be continuing (other than an Event of
Default with respect to the Borrower described in clause (h) of the preceding
 
                                      71
<PAGE>
 
paragraph), the Notes shall not become due and payable until the earlier to
occur of (x) five Business Days following delivery of written notice of such
acceleration of the Notes to the agent under the Bank Credit Facility and (y)
the acceleration (ipso facto or otherwise) of any Indebtedness under the Bank
Credit Facility. If an Event or Default specified in clause (h) of the
preceding paragraph with respect to the Borrower occurs under an Indenture,
the Notes outstanding thereunder will ipso facto become immediately due and
payable without any declaration or other act on the part of the Trustee
thereunder or any holder of such Notes.
 
  Any such declaration with respect to the Notes may be annulled and past
Events of Default and Defaults (except, unless theretofore cured, an Event of
Default or a Default in payment of principal of (and premium, if any) or
interest on the Notes) may be waived by the holders of a majority of the
principal amount of the outstanding Senior Subordinated Notes or a majority of
the principal amount of maturity of the outstanding Senior Subordinated
Discount Notes, as the case may be, upon the conditions provided in the
applicable Indenture. For information as to waiver of defaults, see "--
Modification and Waiver" above.
 
  Each Indenture provides that the Trustee thereunder shall, within 30 days
after the occurrence of any Default or Event of Default with respect to the
Notes outstanding thereunder, give the holders of such Notes thereof notice of
all uncured Defaults or Events of Default thereunder known to it; provided,
however, that, except in the case of an Event of Default in payment with
respect to such Notes or a Default or Event of Default in complying with "--
Certain Covenants--Merger, Sale of Assets, etc." above, the applicable Trustee
shall be protected in withholding such notice if and so long as a committee of
its trust officers in good faith determines that the withholding of such
notice is in the interest of the holders of the applicable Notes.
 
  No holder of any Note will have any right to institute any proceeding with
respect to the relevant Indenture or for any remedy thereunder, unless such
holder shall have previously given to the applicable Trustee written notice of
a continuing Event of Default thereunder and unless the holders of at least
25% of the aggregate principal face amount of the outstanding Senior
Subordinated Notes or the holders of at least 25% of the aggregate principal
amount of maturity of the outstanding Senior Subordinated Discount Notes, as
the case may be, under such Indenture shall have made written request, and
offered reasonable indemnity, to the relevant Trustee to institute such
proceeding as Trustee, and such Trustee shall have not have received from the
holders of a majority in aggregate principal face amount of such outstanding
Senior Subordinated Notes or the holders of a majority in aggregate principal
amount at maturity of such outstanding Senior Subordinated Discount Notes, as
the case may be, a direction inconsistent with such request and shall have
failed to institute such proceeding within 60 days. However, such limitations
do not apply to a suit instituted by a holder of such a Note for enforcement
of payment of the principal of and premium, if any, or interest on such Note
on or after the respective due dates expressed in such Note.
 
  The Borrower will be required to furnish to each Trustee annually a
statement as to the performance by it of certain of its obligations under the
applicable Indenture and as to any default in such performance.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES, INCORPORATOR AND
STOCKHOLDERS
 
  No director, officer, employee, incorporator or stockholder of the Borrower
or any of its Affiliates, as such, shall have any liability for any
obligations of the Borrower or any of its Affiliates under the Notes or the
Notes Indentures or for any claim based on, in respect of, or by reason of,
such obligations or their creation. Each holder of 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.
 
SATISFACTION AND DISCHARGE OF NOTES INDENTURES; DEFEASANCE
 
  The Borrower may terminate its substantive obligations in respect of either
tranche of the Notes by delivering all outstanding Notes of such tranche to
the applicable Trustee for cancellation and paying all sums payable by it on
account of principal of, premium, if any, and interest on all Notes of such
tranche or otherwise. In addition to the foregoing, the Borrower may, provided
that no Default or Event of Default has occurred and is continuing or would
arise therefrom (or, with respect to a Default or Event of Default specified
in clause (i) of
 
                                      72
<PAGE>
 
"--Events of Default" above, occurs at any time on or prior to the 91st
calendar day after the date of such deposit (it being understood that this
condition shall not be deemed satisfied until after such 91st day)) under the
applicable Indenture and provided that no default under any Senior
Indebtedness would result therefrom, terminate its substantive obligations in
respect of the Notes issued under such Indenture (except for its obligations
to pay the principal of (and premium, if any, on) and the interest on such
Notes) by (i) depositing with the relevant Trustee, under the terms of an
irrevocable trust agreement, money or United States Government Obligations
sufficient (without reinvestment) to pay all remaining indebtedness on such
Notes; (ii) delivering to the relevant Trustee either an Opinion of Counsel or
a ruling directed to such Trustee from the Internal Revenue Service to the
effect that the holders of the relevant Notes will not recognize income, gain
or loss for federal income tax purposes as a result of such deposit and
termination of obligations; (iii) delivering to the relevant Trustee an
Opinion of Counsel to the effect that the Borrower's exercise of its option
under this paragraph will not result in any of the Borrower, the relevant
Trustee or the relevant trust created by the Borrower's deposit of funds
pursuant to this provision becoming or being deemed to be an "investment
company" under the Investment Company Act of 1940, as amended (the "Investment
Act"); and (iv) complying with certain other requirements set forth in such
Indenture. In addition, the Borrower may, provided that no Default or Event of
Default has occurred and is continuing or would arise therefrom (or, with
respect to a Default or Event of Default specified in clause (i) of "--Events
of Default" above, occurs at any time on or prior to the 91st calendar day
after the date of such deposit (it being understood that this condition shall
not be deemed satisfied until after such 91st day)) under the applicable
Indenture and provided that no default under any Senior Indebtedness would
result therefrom, terminate all of its substantive obligations in respect of
the Notes issued under such Notes Indenture (including its obligations to pay
the principal of (and premium, if any, on) and interest on such Notes) by (i)
depositing with the relevant Trustee, under the terms of an irrevocable trust
agreement, money or United States Government Obligations sufficient (without
reinvestment) to pay all remaining Indebtedness on such Notes; (ii) delivering
to the relevant Trustee either a ruling directed to such Trustee from the
Internal Revenue Service to the effect that the holders of such Notes will not
recognize income, gain or loss for federal income tax purposes as a result of
such deposit and termination of obligations or an Opinion of Counsel addressed
to the relevant Trustee based upon such a ruling or based on a change in the
applicable federal tax law since the date of such Indenture, to such effect;
(iii) delivering to the relevant Trustee an Opinion of Counsel to the effect
that the Borrower's exercise of its option under this paragraph will not
result in any of the Borrower, such Trustee or the relevant trust created by
the Borrower's deposit of funds pursuant to this provision becoming or being
deemed to be an "investment company" under the Investment Act; and (iv)
complying with certain other requirements set forth in such Indenture.
 
  The Borrower may make an irrevocable deposit pursuant to this provision
pursuant to either Indenture only if at such time it is not prohibited from
doing so under the subordination provisions of such Indenture or certain
covenants in the Senior Indebtedness and the Borrower has delivered to the
applicable Trustee and any Paying Agent an Officers' Certificate to that
effect.
 
GOVERNING LAW
 
  The Indentures and the Notes will be governed by the laws of the State of
New York without regard to principles of conflicts of laws.
 
MODIFICATION AND WAIVER
 
  Modifications and amendments of either Indenture may be made by the Borrower
and the Trustee thereunder with the consent of the holders of a majority in
aggregate principal face amount of the Senior Subordinated Notes outstanding
thereunder or of the holders of a majority in aggregate principal amount at
maturity of the Senior Subordinated Discount Notes outstanding thereunder, as
the case may be (including consents obtained in connection with a tender offer
or exchange offer for such Notes); provided, however, that no such
modification or amendment to the applicable Indenture may, without the consent
of the holder of each Note affected thereby, (a) change the maturity of the
principal of or any installment of interest on any such Note or alter the
optional redemption or repurchase provisions of any such Note or such
Indenture in a manner adverse to the holders of
 
                                      73
<PAGE>
 
such Notes; (b) reduce the principal amount of (or the premium) of any such
Note (except pursuant to the Cash Election); (c) reduce the rate of or extend
the time for payment of interest on any such Note or make any change to the
definition of Accreted Value; (d) change the place or currency of payment of
principal of (or premium) or interest on any such Note; (e) modify any
provisions of such Indenture relating to the waiver of past defaults (other
than to add sections of such Indenture or such Notes subject thereto) or the
right of the holders of Notes outstanding thereunder to institute suit for the
enforcement of any payment on or with respect to any such Note in respect
thereof or the modification and amendment provisions of such Indenture and
such Notes (other than to add sections of such Indenture or such Notes which
may not be amended, supplemented or waived without the consent of each holder
herein affected); (f) reduce the percentage of the principal amount of
outstanding Notes necessary for amendment to or waiver of compliance with any
provision of the applicable Indenture or the Notes outstanding thereunder or
for waiver of any Default in respect thereof; (g) waive a default in the

such Note (except a rescission of acceleration of the relevant Notes by the
holders thereof as provided in such Indenture and a waiver of the payment
default that resulted from such acceleration); (h) modify the ranking or
priority of any Note or modify the definition of Senior Indebtedness or
Guarantor Senior Indebtedness or amend or modify the subordination provisions
of the applicable Indenture in any manner adverse to the holders of the
applicable Notes; or (i) modify the provisions of any covenant (or the related
definitions) in the applicable Indenture requiring the Borrower to make an
Offer to Purchase in a manner materially adverse to the holders of Notes
thereunder affected thereby.
 
  The holders of a majority in aggregate principal face amount of the
outstanding Senior Subordinated Notes and the holders of a majority in
aggregate principal amount at maturity of the outstanding Senior Subordinated
Discount Notes, on behalf of all holders of Notes of such tranche, may waive
compliance by the Borrower with certain restrictive provisions of the
applicable Indenture. Subject to certain rights of the relevant Trustee, as
provided in the applicable Indenture, the holders of a majority in aggregate
principal amount of the Senior Subordinated Notes and the holders of a
majority in aggregate principal amount at maturity of the Senior Subordinated
Discount Notes, on behalf of all holders of Notes of such tranche outstanding
thereunder, may waive any past default under such Indenture (including any
such waiver obtained in connection with a tender offer or exchange offer for
such Notes), except a default in the payment of principal, premium or interest
or a default arising from failure to purchase any Notes of such tranche
tendered pursuant to an Offer to Purchase pursuant thereto, or a default in
respect of a provision that under such Indenture cannot be modified or amended
without the consent of the holder of each Note outstanding thereunder that is
affected.
 
THE TRUSTEES
 
  Except during the continuance of a Default, each Trustee will perform only
such duties as are specifically set forth in the Indenture to which it is a
party. During the existence of a Default under an Indenture, the applicable
Trustee will exercise such rights and powers vested in it under such Indenture
and use the same degree of care and skill in their exercise as a prudent
person would exercise under the circumstances in the conduct of such person's
own affairs.
 
  The Indentures and provisions of the TIA incorporated by reference therein
contain limitations on the rights of the Trustees, should they become a
creditor of the Borrower or any other obligor upon the Notes, to obtain
payment of claims in certain cases or to realize on certain property received
by it in respect of any such claim as Note or otherwise. Each Trustee is
permitted to engage in other transactions with the Borrower or an Affiliate of
the Borrower; provided, however, that if it acquires any conflicting interest
(as defined in each Indenture or in the TIA), it must eliminate such conflict
or resign.

  Except as set forth in the next paragraph, the Senior Subordinated Exchange
Notes and the Senior Subordinated Discount Exchange Notes to be issued
pursuant to the Exchange Offer initially will be issued in the form of one or
more senior subordinated global exchange notes and senior subordinated
discount global exchange notes, as the case may be (the "Global Notes"). The
Global Notes will be deposited on the Expiration Date of the Exchange Offer
with, or on behalf of, the Depository and registered in the name of Cede &
Co., as nominee of the Depository (such nominee being referred to herein the
"Global Notes Holder").
 
  Notes that are issued as described below under "--Certificated Notes" will
be issued in the form of registered definitive certificates (the "Certificated
Notes"). Such Certificated Notes may, unless the applicable Global Note has
previously been exchanged for Certificated Notes, be exchanged for an interest
in the applicable Global Note representing the principal amount of Senior
Subordinated Exchange Notes or Senior Subordinated Discount Exchange Notes, as
the case may be, being transferred.
 
  The Depository is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the
"Participants" or the "Depository's Participants") and to facilitate the
clearance and settlement of transactions in such securities between
Participants through electronic book-entry changes in the accounts of such
Participants. The Depository's Participants include securities brokers and
dealers, banks and trust companies, clearing corporations and certain other
organizations. Access to the Depository's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively,
the "Indirect Participants" or the "Depository's Indirect Participants") that
clear through or maintain a custodial relationship with a Participant, either
directly or indirectly. Persons who are not Participants may beneficially own
securities held by or on behalf of the Depository only through the
Depository's Participants or the Depository's Indirect Participants.
 
                                      91

  The Borrower expects that, pursuant to procedures established by the
Depository, ownership of the Senior Subordinated Notes or Senior Subordinated
Discount Notes, as the case may be, evidenced by the Global Notes, will be
shown on, and the transfer of ownership thereof will be effected only through,
records maintained by the Depository (with respect to the interests of the
Depository's Participants), the Depository's Participants and the Depository's
Indirect Participants. Prospective purchasers are advised that the laws of
some states require that certain persons take physical delivery in definitive
form of securities that they own. Consequently, the ability to transfer Senior
Subordinated Notes or Senior Subordinated Discount Notes, as the case may be,
evidenced by the Global Notes, will be limited to such extent.
 
  So long as the Global Notes Holder is the registered owner of any Notes, the
Global Notes Holder will be considered the sole holder under the applicable
Indenture of any Senior Subordinated Notes or Senior Subordinated Discount
Notes, as the case may be, evidenced by the Global Notes. Beneficial owners of
Notes evidenced by the Global Notes will not be considered the owners or
holders thereof under the applicable Indenture for any purpose, including with
respect to the giving of any directions, instructions or approvals to the
applicable agent or trustee thereunder. As a result, the ability of a person
having a beneficial interest in Notes represented by any Global Note to pledge
such interest to persons or entities that do not participate in the
Depository's system or to otherwise take actions in respect of such interest
may be affected by the lack of a physical certificate evidencing such
interest. Neither the Borrower nor the Trustees will have any responsibility
or liability for any aspect of the records relating to or payments made on
account of the Notes by the Depository, or for maintaining, supervising or
reviewing any records of the Depository relating to the Notes.
 
  Payments in respect of the principal of, premium, if any, and interest on
any Notes registered in the name of the Global Notes Holder on the applicable
record date will be payable by the applicable Trustee to or at the direction
of the Global Notes Holder in its capacity as the registered holder of such
Notes. Under the terms of the Notes Indentures, the Borrower and the Trustees
may treat the persons in whose names Notes, including the Global Notes, are
registered as the owners thereof for the purpose of receiving such payments.
Consequently, neither the Borrower nor the Trustees have or will have any
responsibility or liability for the payment of such amounts to beneficial
owners of Notes. The Borrower believes, however, that it is currently the
policy of the Depository to immediately credit the accounts of the relevant
Participants with such payments, in amounts proportionate to their respective
holders of beneficial interests in the relevant security as shown on the
records of the Depository. Payments by the Depository's Participants and the
Depository's Indirect Participants to the beneficial owners of Notes will be
governed by standing instructions and customary practice and will be the
responsibility of the Depository's Participants or the Depository's Indirect
Participants.
 
CERTIFICATED NOTES
 
  Subject to certain conditions, any person having a beneficial interest in a
Global Note may, upon request to the applicable Trustee, exchange such
beneficial interest for Senior Subordinated Notes or Senior Subordinated
Discount Notes, as the case may be, in the form of Certificated Notes. Upon
any such issuance, the applicable Trustee is required to register such
Certificated Notes in the name of, and cause the same to be delivered to, such
person or persons (or the nominee of any thereof). If: (i) the Borrower
notifies the applicable Trustee in writing that the Depository is no longer
willing or able to act as a depository and the Borrower is unable to locate a
qualified successor within 90 days; or (ii) an Event of Default has occurred
and is continuing and the Depository requests that Certificated Notes be
issued under the applicable Indenture, then, upon surrender by the Global
Notes Holder of the applicable Global Notes, Senior Subordinated Notes and
Senior Subordinated Discount Notes, as the case may be, in such form will be
issued to each person that the Global Notes Holder and the Depository identify
as being the beneficial owner of the related Senior Subordinated Notes or
Senior Subordinated Discount Notes, as the case may be.
 
  Neither the Borrower nor the applicable Trustee will be liable for any delay
by the Global Notes Holder or the Depository in identifying the beneficial
owners of the Senior Subordinated Notes or Senior Subordinated Discount Notes,
as the case may be, and the Borrower and the applicable Trustee may
conclusively rely on, and will be protected in relying on, instructions from
the Global Notes Holder or the Depository for all purposes.

REGISTRATION RIGHTS
 
 Exchange Offer
 
  (a) Pursuant to the Registration Rights Agreements executed in connection
with the Notes Offering, the Borrower has agreed to file with the SEC on or
before the Filing Date, an offer to exchange any and all of the Notes that
constitute Registrable Securities (as defined below) for a like aggregate
principal amount of senior subordinated debt securities of the Borrower which
are identical to the Notes, and which are entitled to the benefits of a trust
indenture which is identical to the applicable Indenture (other than such
changes as are necessary to comply with any requirements of the SEC to effect
or maintain the qualification of such trust indenture under the TIA) and which
has been qualified under the TIA (the "Exchange Securities"), except that the
Exchange Securities shall have been registered pursuant to an effective
registration statement under the Securities Act and shall contain no
restrictive legend thereon. The Exchange Notes are intended to constitute
Exchange Securities under the Registration Rights Agreement. The Borrower has
agreed to use its commercially reasonable best efforts to (i) cause such
registration statement to become effective and commence such exchange offer on
or prior to the Effectiveness Date, (ii) keep such exchange offer open for 20
business days (or longer if required by applicable law) (the last day of such
period, the "Expiration Date") and (iii) exchange Exchange Notes for all Notes
validly tendered and not withdrawn pursuant to such exchange offer on or prior
to the fifth day following the Expiration Date.
 
  The Borrower has agreed to use its commercially reasonable best efforts to
keep such registration statement effective and to amend and supplement the
prospectus forming a part thereof in order to permit such prospectus to be
lawfully delivered by all persons subject to the prospectus delivery
requirements of the Securities Act for at least 180 days (or such shorter time
as such persons must comply with such requirements in order to resell the
Exchange Securities) (the "Applicable Period").
 
  The Exchange Offer and the Registration Statement (of which this Prospectus
constitutes a part) filed in connection with the Exchange Offer are intended
to satisfy the Borrower's obligations under the Registration Rights
Agreements. If the Borrower does not consummate the Exchange Offer, or, in
lieu thereof, the Borrower does not file and cause to become effective a
resale shelf registration for the Notes within the time periods set forth
herein, special interest will accrue and be payable on the Notes either
temporarily or permanently.
 
  (b) Although the Borrower has filed the Registration Statement in
satisfaction of its obligations under the Registration Rights Agreements, as
previously described, there can be no assurance that the Registration
Statement will become effective. If, (i) because of any change in law or in
currently prevailing interpretations of the Staff of the SEC, the Borrower
reasonably determines in good faith, after consultation with counsel, that it
is not permitted to effect the Exchange Offer, (ii) the Exchange Offer is not
commenced on or prior to the Effectiveness Date, (iii) the Exchange Offer is
not, for any reason, consummated on or prior to the 165th day after the Issue
Date, (iv) any holder of Private Exchange Securities (as defined in the
Registration Rights Agreement) so requests, or (v) in the case of any holder
that participates in the Exchange Offer, such holder does not receive Exchange
Securities on the date of the exchange that may be sold without restriction
under state and federal securities laws (the occurrence of any such event, a
"Shelf Registration Event"), then, in the case of each of clauses (i) to and
including (v) of this sentence, the Borrower shall promptly deliver to the
holders and the Trustee notice thereof (the "Shelf Notice") and shall
thereafter file an Initial Shelf Registration Statement pursuant to the terms
of the Registration Rights Agreements.
 
 Shelf Registration
 
  If a Shelf Registration Event has occurred (and whether or not this
Registration Statement has become effective, or the Exchange Offer has been
consummated), then:
 
    (a) Initial Shelf Registration Statement. The Borrower shall promptly
  prepare and file with the SEC a Registration Statement for an offering to
  be made on a continuous basis pursuant to Rule 415 covering all of the
  Registrable Securities (the "Initial Shelf Registration Statement"). The
  Borrower shall file with the
 
                                      93
<PAGE>
 
  SEC the Initial Shelf Registration Statement on or prior to the Filing
  Date. The Initial Shelf Registration Statement shall be on Form S-1 or
  another appropriate form if available, permitting registration of such
  Registrable Securities for resale by such holders in the manner designated
  by them (including, without limitation, in one or more underwritten
  offerings). The Borrower shall not permit any securities other than the
  Registrable Securities to be included in the Initial Shelf Registration
  Statement or any Subsequent Shelf Registration Statement. The Borrower
  shall use its commercially reasonable best efforts to cause the Initial
  Shelf Registration Statement to be declared effective under the Securities
  Act on or prior to the Effectiveness Date, and to keep the Initial Shelf
  Registration Statement continuously effective under the Securities Act
  until the date which is 36 months from the Issue Date, or such shorter
  period ending when (i) all Registrable Securities covered by the Initial
  Shelf Registration Statement have been sold in the manner set forth and as
  contemplated in the Initial Shelf Registration Statement or (ii) a
  Subsequent Shelf Registration Statement covering all of the Registrable
  Securities has been declared effective under the Securities Act (such 36
  month or shorter period, the "Effectiveness Period").
 
    (b) Subsequent Shelf Registration Statements. If the Initial Shelf
  Registration Statement or any Subsequent Shelf Registration Statement
  ceases to be effective for any reason at any time during the Effectiveness
  Period (other than because of the sale of all of the securities registered
  thereunder), the Borrower shall use its best efforts to obtain the prompt
  withdrawal of any order suspending the effectiveness thereof, and in any
  event the Borrower shall within 45 days of such cessation of effectiveness
  amend the Shelf Registration Statement in a manner reasonably expected to
  obtain the withdrawal of the order suspending the effectiveness thereof, or
  file an additional "shelf" Registration Statement pursuant to Rule 415
  covering all of the Registrable Securities (a "Subsequent Shelf
  Registration Statement"). If a Subsequent Shelf Registration Statement is
  filed, the Borrower shall use its commercially reasonable best efforts to
  cause the Subsequent Shelf Registration Statement to be declared effective
  as soon as reasonably practicable after such filing and to keep such
  Registration Statement continuously effective until the end of the
  Effectiveness Period. As used herein the term "Shelf Registration
  Statement" means the Initial Shelf Registration Statement and any
  Subsequent Shelf Registration Statement.
 
    (c) Supplements and Amendments. The Borrower shall promptly supplement
  and amend the Shelf Registration Statement if required by the rules,
  regulations or instructions applicable to the registration form used for
  such Shelf Registration Statement, if required by the Securities Act, or if
  reasonably requested by the holders of a majority in aggregate principal
  amount of the Registrable Securities covered by such Registration Statement
  or by any underwriter of such Registrable Securities.
 
 Additional Interest
 
  The Borrower has agreed to pay, as liquidated damages, additional interest
on the Notes ("Additional Interest") under the circumstances and to the extent
set forth below (each of which shall be given independent effect):
 
    (i) if either the Registration Statement or the Initial Shelf
  Registration Statement has not been filed on or prior to the Filing Date
  (unless, with respect to the Registration Statement, a Shelf Event
  described in clause (i) of paragraph (b) of "--Exchange Offer" above shall
  have occurred prior to the Filing Date), Additional Interest shall accrue
  on the Notes over and above the stated interest in an amount equal to $0.05
  per week (or any part thereof), per $1,000 principal amount of the Senior
  Subordinated Notes or $1,000 of Accreted Value (as of the first day of each
  such week) with respect to the Senior Subordinated Discount Notes for the
  first 90 days immediately following such date, such Additional Interest
  increasing by an additional $0.05 per week (or any part thereof) per $1,000
  principal amount of the Senior Subordinated Notes or $1,000 of Accreted
  Value (as of the first day of each such week) with respect to the Senior
  Subordinated Discount Notes for each subsequent 90-day period;
 
    (ii) if either the Registration Statement or the Initial Shelf
  Registration Statement is not declared effective by the SEC on or prior to
  the Effectiveness Date (unless, with respect to the Registration Statement,
  a Shelf Event described in clause (i) of paragraph (b) of "--Exchange
  Offer" above shall have occurred), Additional Interest shall accrue on the
  Notes included or which should have been included in
 
                                      94
<PAGE>
 
  such Registration Statement over and above the stated interest in an amount
  equal to $0.05 per week (or any part thereof) per $1,000 principal amount
  of Senior Subordinated Notes or $1,000 of Accreted Value (as of the first
  day of each such week) with respect to the Senior Subordinated Discount
  Notes for the first 90 days immediately following the day after such date,
  such Additional Interest increasing by an additional $0.05 per week (or any
  part thereof) per $1,000 principal amount of the Senior Subordinated Notes
  or $1,000 of Accreted Value (as of the first day of each such week) with
  respect to the Senior Subordinated Discount Notes for each subsequent 90-
  day period; and
 
    (iii) if (A) The Borrower has not exchanged Exchange Securities for all
  Notes validly tendered and not withdrawn in accordance with the terms of
  the Exchange Offer on or prior to the fifth day after the Expiration Date,
  or (B) the Registration Statement ceases to be effective at any time prior
  to the Expiration Date, or (C) if applicable, any Shelf Registration
  Statement has been declared effective and such Shelf Registration Statement
  ceases to be effective at any time during the Effectiveness Period, then
  Additional Interest shall accrue on the Notes (over and above any interest
  otherwise payable on the Notes) in an amount equal to $0.05 per week (or
  any part thereof) per $1,000 principal amount of the Senior Subordinated
  Notes or $1,000 of Accreted Value (as of the first day of each such week)
  with respect to the Senior Subordinated Discount Notes for the first 90
  days commencing on the (x) sixth day after the Expiration Date, in the case
  of (A) above, or (y) the day the Registration Statement ceases to be
  effective in the case of (B) above, or (z) the day such Shelf Registration
  Statement ceases to be effective in the case of (C) above, such Additional
  Interest increasing by an additional $0.05 per week (or any part thereof)
  per $1,000 principal amount of the Senior Subordinated Notes or $1,000 of
  Accreted Value (as of the first day of each such week) with respect to the
  Senior Subordinated Discount Notes at the beginning of each such subsequent
  90-day period; provided, however, that the Additional Interest rate on the
  Notes may not exceed at any one time in the aggregate $0.50 per week per
  $1,000 principal amount of the Senior Subordinated Notes or $1,000 of
  Accreted Value (as of the first day of each such week) with respect to the
  Senior Subordinated Discount Notes; provided, further, that (1) upon the
  filing of the Registration Statement or a Shelf Registration Statement as
  required hereunder (in the case of clause (i) of this paragraph), (2) upon
  the effectiveness of the Registration Statement or the Shelf Registration
  Statement as required hereunder (in the case of clause (ii) of this
  paragraph) or (3) upon the exchange of Exchange Securities for all Notes
  validly tendered and not withdrawn (in the case of clause (iii)(A) of this
  paragraph), or upon the effectiveness of the Registration Statement which
  had ceased to remain effective (in the case of (iii)(B) of this paragraph),
  or upon the effectiveness of the Shelf Registration Statement which had
  ceased to remain effective (in the case of (iii)(C) of paragraph),
  Additional Interest on the Notes as a result of such clause (or the
  relevant subclause thereof), as the case may be, shall cease to accrue (but
  any accrued amount shall be payable).
 
  Although the Borrower initially filed a registration statement in connection
with the Exchange Offer with the SEC on April 11, 1997, in light of the
proposed Roll-up Plan and the consequent necessity of preparing and providing
to holders of the Notes certain pro forma financial information which gives
effect to the Roll-up Plan, the Borrower did not cause such registration
statement to be declared effective. As a result, effective July 5, 1997, the
Borrower began to incur Additional Interest on the Notes, in accordance with
the Registration Rights Agreements, as described above. During the 90-day
periods ended October 3, 1997 and January 3, 1998, the Borrower incurred
approximately $252,000 and $476,000, respectively, of Additional Interest, and
will continue to incur Additional Interest for each subsequent 90-day period,
in accordance with the Registration Rights Agreements, until the Registration
Statement of which this Prospectus is a part is declared effective by the SEC
and the Exchange Offer is consummated.

                  RECENT TRANSACTIONS--THE ASKYB TRANSACTION
 
  In the proposed ASkyB Transaction, pursuant to the ASkyB Agreement among the
Partnership, News Corp., MCI, ASkyB, and for certain purposes only, each of
the Partners, New PRIMESTAR will acquire from MCI, News Corp. and ASkyB, as
applicable, two MCI Satellites, certain authorizations granted to MCI by the
FCC to operate a DBS business at the 110(degrees) W.L. orbital location using
28 transponder channels, and certain related contracts.
 
  In consideration, ASkyB will receive non-voting convertible securities of
New PRIMESTAR, comprising, subject to closing adjustments, approximately $600
million liquidation value of New PRIMESTAR Convertible Preferred Stock
(convertible into approximately 52 million shares of non-voting New PRIMESTAR
Class D Common Stock, subject to adjustment) and approximately $516 million
principal amount of New PRIMESTAR Convertible Subordinated Notes (convertible
into approximately 45 million shares of New PRIMESTAR Class D Common Stock).
The New PRIMESTAR Convertible Subordinated Notes will be due and payable, and
the New PRIMESTAR Convertible Preferred Stock will be mandatorily redeemable,
on the tenth anniversary of the date of issuance. The New PRIMESTAR
Convertible Preferred Stock will accrue cumulative dividends at the annual
rate of 5% of the liquidation value of such shares and the New PRIMESTAR
Convertible Subordinated Notes will have an interest rate of 5%. Dividends on
the New PRIMESTAR Convertible Preferred Stock and interest on the New
PRIMESTAR Convertible Subordinated Notes will be payable in cash or, at the
option of New PRIMESTAR, in shares of the non-voting New PRIMESTAR Class D
Common Stock, for a period of four years. Thereafter, all dividend and
interest payments will be made solely in cash. Shares of New PRIMESTAR Class D
Common Stock issued to ASkyB or any of its affiliates upon conversion of such
New PRIMESTAR Convertible Preferred Stock and New PRIMESTAR Convertible
Subordinated Notes, or in payment of dividend or interest obligations
thereunder, will in turn automatically convert into shares of New PRIMESTAR
Class A Common Stock, on a one-to-one basis, upon transfer to any person other
than ASkyB, News Corp. or any of their respective affiliates. Assuming such a
transfer and conversion, and based on the number of shares of New PRIMESTAR
Common Stock expected to be issued in the Restructuring Transaction (subject
to adjustment as provided in the Restructuring Agreement, the New PRIMESTAR
Class D Common Stock into which the New PRIMESTAR Convertible Subordinated
Notes and the New PRIMESTAR Convertible Preferred Stock are convertible, would
be converted into New PRIMESTAR Class A Common Stock representing
approximately
 
                                      96
<PAGE>
 
33% of the number of shares of New PRIMESTAR Common Stock and approximately
20% of the combined voting power of the New PRIMESTAR Common Stock outstanding
after giving effect to such a transfer and conversion.
 
  Consummation of the ASkyB Transaction is contingent on, among other things,
receipt of all necessary government and regulatory approvals, and accordingly,
no assurance can be given that the ASkyB Transaction will be consummated. In
addition, it is a condition precedent to the closing of the ASkyB Transaction
by New PRIMESTAR that the ASkyB Transaction be approved by the holders of New
PRIMESTAR Voting Common Stock, including the former holders of TSAT Common
Stock if the TSAT Merger shall have been consummated, at an annual or special
meeting of New PRIMESTAR. The ASkyB Agreement provides that if the
Restructuring Transaction has not closed by March 8, 1998, and the closing
conditions set forth in the ASkyB Agreement have all been satisfied, then News
Corp., MCI and ASkyB (collectively, the "ASkyB Transferors") will have the
right to transfer to the Partnership the assets contemplated to be transferred
to New PRIMESTAR under the ASkyB Transaction, in exchange for such
consideration, having an aggregate fair market value equal to the aggregate
consideration that would have been received by the ASkyB Transferors pursuant
to the ASkyB Transaction had the Restructuring Transaction closed by such
date, as the Partnership and the ASkyB Transferors shall mutually agree.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  The following summary describes the principal United States federal income
tax consequences of the ownership and disposition of the Notes and the
Exchange Notes. This summary is based on the Code, administrative
pronouncements, judicial decisions and existing and proposed Treasury
Regulations, changes to any of which subsequent to the date hereof may affect
the tax consequences described below. This summary addresses only initial
holders of the Notes who acquired such Notes at their "issue price," as
defined below, and initial holders of Notes who, upon tendering their Notes in
connection with the Exchange Offer, are issued Exchange Notes in exchange for
such Notes, and discusses only Notes and Exchange Notes held as capital assets
within the meaning of Section 1221 of the Code. It does not discuss all of the
tax consequences that may be relevant to a holder in light of such holder's
particular circumstances or to holders subject to special rules, such as
certain financial institutions, insurance companies, dealers in securities or
persons holding the Notes as part of a straddle or a hedging arrangement.
 
  THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION AND IS NOT TAX ADVICE.
ACCORDINGLY, HOLDERS OF NOTES SHOULD CONSULT THEIR TAX ADVISORS WITH REGARD TO
THE APPLICATION OF THE UNITED STATED FEDERAL INCOME TAX LAWS TO THEIR
PARTICULAR SITUATIONS, AS WELL AS WITH REGARD TO ANY TAX CONSEQUENCES ARISING
UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN JURISDICTION AND ANY RECENT OR
PROSPECTIVE CHANGES IN APPLICABLE TAX LAWS.
 
SENIOR SUBORDINATED DISCOUNT NOTES
 
  Original Issue Discount. The Senior Subordinated Discount Notes were issued
with OID equal to the difference between their "stated redemption price at
maturity" and their "issue price," as such terms are defined in the Code and
Treasury Regulations. The "issue price" of a Senior Subordinated Discount
Note, or a Senior Subordinated Exchange Note issued in exchange therefor
pursuant to the Exchange Offer, is the first price at which a substantial
amount of the Senior Subordinated Discount Notes was sold to the public. For
this purpose, the public does not include bond houses, brokers or similar
persons or organizations acting in the capacity of underwriters, placement
agents or wholesalers.
 
  The "stated redemption price at maturity" of a Senior Subordinated Discount
Note, or of a Senior Subordinated Discount Exchange Note issued in exchange
therefor, is equal to the sum of all payments required
 
                                      97
<PAGE>
 
under the Senior Subordinated Discount Note or Senior Subordinated Discount
Exchange Note, as the case may be, other than payments of "qualified stated
interest" within the meaning of the Treasury Regulations. To have "qualified
stated interest," an instrument must, among other requirements, pay interest
at least annually during the entire term of such instrument. Because neither
the Senior Subordinated Discount Notes nor the Senior Subordinated Discount
Exchange Notes will pay interest until September 1, 2002, none of the interest
on the Senior Subordinated Discount Notes or the Senior Subordinated Discount
Exchange Notes will be qualified stated interest. As a result, all payments
made under the Senior Subordinated Discount Notes and the Senior Subordinated
Discount Exchange Notes will be treated as part of the stated redemption price
at maturity, and interest paid on the Senior Subordinated Discount Notes and
the Senior Subordinated Discount Exchange Notes will not be taxable upon
receipt, but the OID rules described below will apply. The total OID on a
Senior Subordinated Discount Note or a Senior Subordinated Discount Exchange
Note, as the case may be, will be equal to the difference between the sum of
all payments required under such Senior Subordinated Discount Note or Senior
Subordinated Discount Exchange Note and the issue price of the Senior
Subordinated Discount Note owned by the holder (or, in the case of a Senior
Subordinated Discount Exchange Note, the issue price of the Senior
Subordinated Discount Note that was exchanged by such holder for a Senior
Subordinated Discount Exchange Note pursuant to the Exchange Offer).
 
  A holder of Senior Subordinated Discount Notes and a holder of Senior
Subordinated Discount Exchange Notes each will be required to include OID in
income for U.S. federal income tax purposes as it accrues, whether or not such
holder uses the accrual method of accounting. OID will accrue in accordance
with a constant yield method based on a compounding of interest. Under this
method, holders of Senior Subordinated Discount Notes and holders of Senior
Subordinated Discount Exchange Notes will be required to include in income
increasingly greater amounts of OID in successive accrual periods. OID
allocable to any accrual period will equal the product of the "adjusted issue
price" of the Senior Subordinated Discount Notes or the Senior Subordinated
Discount Exchange Notes, as the case may be, as of the beginning of such
period, multiplied by the Senior Subordinated Discount Notes' or the Senior
Subordinated Discount Exchange Notes' respective yield to maturity. The
"adjusted issue price" of the Senior Subordinated Discount Notes, or the
Senior Subordinated Discount Exchange Notes issued in exchange for Senior
Subordinated Discount Notes, as of the beginning of any accrual period, will,
with respect to Senior Subordinated Discount Notes, equal the issue price of
the Senior Subordinated Discount Notes or, with respect to the Senior
Subordinated Discount Exchange Notes, equal the issue price of the Senior
Subordinated Discount Note that was exchanged pursuant to the Exchange Offer,
increased, in each case, by OID previously includible in income and decreased
by any payments under such Notes or Exchange Notes, as the case may be.
Because OID will accrue and be includible in income at least annually and no
payments will be made under the Senior Subordinated Discount Notes and the
Senior Subordinated Discount Exchange Notes until August 15, 2002, the
adjusted issue price of the Senior Subordinated Discount Notes and the Senior
Subordinated Discount Exchange Notes will increase until February 15, 2002.
OID includible in income will therefore increase during each accrual period
until February 15, 2002. Thereafter, OID includible in income for each six-
month accrual period will approximate the amount of cash interest due at the
end of such period.
 
  The Borrower may make a Cash Interest Election at any time prior to February
15, 2002, in which case cash interest is payable on each interest payment date
thereafter. Under the OID rules, solely for purposes of determining the amount
of OID that is includible in income by a holder of a note, it is presumed that
the issuer will exercise an option to pay cash interest early if such exercise
will lower the yield-to-maturity of the note. The Borrower has determined that
the exercise of its option to pay interest early would not lower the yield-to-
maturity of the Senior Subordinated Discount Notes or the yield-to-maturity of
the Senior Subordinated Discount Exchange Notes. On these facts, the Borrower
would not be presumed to exercise its option to pay interest early. However,
if, contrary to such presumption, the Borrower exercises such option, then
solely for purposes of the accrual of OID, the yield to maturity of the Senior
Subordinated Discount Notes and the Senior Subordinated Discount Exchange
Notes will be redetermined by treating each of the Senior Subordinated
Discount Notes and the Senior Subordinated Discount Exchange Notes as reissued
on such date for an amount equal to the adjusted issue price on such date.

  Effect of Mandatory and Optional Redemption on OID. The Borrower may redeem
the Senior Subordinated Discount Notes and the Senior Subordinated Discount
Exchange Notes, in whole or in part, at any time on or after February 15,
2002, at redemption prices specified elsewhere herein, plus accrued and unpaid
interest thereon, if any, to the date of redemption. Treasury Regulations
contain rules for determining the "maturity date" and the stated redemption
price at maturity of an instrument that may be redeemed prior to its stated
maturity date at the option of the issuer. Under the OID rules, solely for
purposes of the accrual of OID, it is assumed that the issuer will exercise
any option to redeem a debt instrument if such exercise will lower the yield-
to-maturity of the debt instrument. The Borrower has determined that the
exercise of its right to redeem the Senior Subordinated Discount Notes and
Senior Subordinated Discount Exchange Notes prior to their stated maturity
under these rules would not lower the yield-to-maturity of the Senior
Subordinated Discount Notes and the Senior Subordinated Discount Exchange
Notes. On these facts, the Borrower would not be presumed to exercise its
right to redeem the Senior Subordinated Discount Notes and Senior Subordinated
Discount Exchange Notes prior to their stated maturity under these rules.
 
  In addition, prior to February 15, 2000, the Borrower, other than in any
circumstance resulting in a Change of Control, may redeem an aggregate
principal amount of Senior Subordinated Discount Notes and Senior Subordinated
Discount Exchange Notes equal to up to 35% of the originally issued principal
amount at maturity of Senior Subordinated Discount Notes at a redemption price
equal to 112.25% of the Accreted Value thereof at the redemption date (or, if
a Cash Interest Election has been made, 112.25% of the principal amount at
maturity thereof, plus accrued and unpaid interest thereon, if any, to the
redemption date) with the net cash proceeds of (i) one or more Public Equity
Offerings of common equity of the Borrower or (ii) a sale or series of related
sales of Qualified Equity Interests of the Borrower to Strategic Equity
Investors, in any such case resulting in gross cash proceeds to the Borrower
of at least $100.0 million in the aggregate, provided, however, that at an
aggregate principal amount of Senior Subordinated Discount Notes and Senior
Subordinated Discount Exchange Notes equal to at least 65% of the originally
issued principal amount at maturity of Senior Subordinated Discount Notes
would remain outstanding immediately after giving effect to any such
redemption (excluding any Senior Subordinated Discount Notes and Senior
Subordinated Discount Exchange Notes owned by the Borrower or any of it
Affiliates). Such redemption rights and obligations will be treated by the
Borrower as not affecting the determination of the yield or maturity of the
Senior Subordinated Discount Notes or the Senior Subordinated Discount
Exchange Notes. The Treasury Regulations contain rules for determining the
"maturity date" and the stated redemption price at maturity of an instrument
that may be redeemed prior to its stated maturity date upon the occurrence of
one or more contingencies. Under such Treasury Regulations, if the timing and
amounts of the payments that comprise each payment schedule are known as of
the issue date, the "maturity date" and stated redemption price at maturity of
such an instrument are determined by assuming that payments will be made
according to the instrument's stated payment schedule, unless, based upon all
the facts and circumstances as of the issue date, it is more likely than not
that the instrument's stated payment schedule will not occur. The Borrower has
determined that the stated maturity date and stated payment schedule of the
Senior Subordinated Discount Notes is more likely than not to occur based on
the facts and circumstances known as of the issue date. On these facts, under
these regulations, the "maturity date" and stated redemption price at maturity
of the Senior Subordinated Discount Notes and the Senior Subordinated Discount
Exchange Notes would be determined on the basis of the stated maturity and
stated payment schedule.
 
  If, notwithstanding the foregoing, it is presumed that the Borrower will
exercise its option to redeem, then the maturity date of the Senior
Subordinated Discount Notes and the Senior Subordinated Discount Exchange
Notes for the purpose of calculating yield to maturity would be the exercise
date of such call option and the stated redemption price at maturity for each
Senior Subordinated Discount Note and each Senior Subordinated Discount
Exchange Note would equal the amount payable upon such exercise. If
subsequently the call option is not exercised, then for purposes of the OID
rules, the issuer would be treated as having issued on the presumed exercise
date of the call option a new debt instrument in exchange for the existing
instrument. The new debt instrument deemed issued would have an issue price
equal to the call price. As a result, another OID computation would have to be
made with respect to the constructively issued new debt instrument.

  Sale, Exchange or Retirement. Upon the sale, exchange or retirement of a
Senior Subordinated Discount Note or of a Senior Subordinated Discount
Exchange Note, a holder will recognize taxable gain or loss equal to the
difference between the amount realized on the sale, exchange or retirement and
such holder's adjusted tax basis in such Senior Subordinated Discount Note or
Senior Subordinated Discount Exchange Note, as the case may be. A holder's
adjusted tax basis in a Senior Subordinated Discount Note or Senior
Subordinated Discount Exchange Note will equal the initial tax basis of the
Senior Subordinated Discount Note or Senior Subordinated Discount Exchange
Note, respectively, increased by the amounts of any OID previously included in
income by the holder with respect to such Senior Subordinated Discount Note or
Senior Subordinated Discount Exchange Note, and reduced by the amounts of any
payments on such Senior Subordinated Discount Note or Senior Subordinated
Discount Exchange Note, respectively, received by such holder.
 
  Gain or loss realized on the sale, exchange or retirement of a Senior
Subordinated Discount Note or Senior Subordinated Discount Exchange Note will
be capital gain or loss if such Senior Subordinated Discount Note or Senior
Subordinated Discount Exchange Note, as the case may be, is held as a capital
asset, and will be long-term capital gain or loss if the Senior Subordinated
Discount Note or Senior Subordinated Discount Exchange Note has been held by
the holder for more than one year as of the date of the sale, exchange or
retirement. Under current law, the excess of net long-term capital gains over
net short-term capital losses is taxed at a lower rate than ordinary income
for certain noncorporate taxpayers. The distinction between capital gain or
loss and ordinary income or loss is also relevant for purposes of, among other
things, any limitation on the deductibility of capital losses.
 
SENIOR SUBORDINATED NOTES
 
  The Senior Subordinated Notes were not issued with (and thus do not bear)
OID, and consequently, any Senior Subordinated Exchange Notes issued in
exchange for Senior Subordinated Notes pursuant to the Exchange Offer will not
bear OID. For purposes of this discussion, it is assumed that all the initial
holders of Senior Subordinated Notes purchased their Senior Subordinated Notes
at a price equal to the stated principal amount.
 
  Holders of Senior Subordinated Notes or Senior Subordinated Exchange Notes
will be required to include stated interest on the Senior Subordinated Notes
or Senior Subordinated Exchange Notes in gross income for federal income tax
purposes in accordance with the holder's method of accounting for tax
purposes.
 
  Sale, Exchange or Retirement Upon the sale, exchange or retirement of a
Senior Subordinated Note or a Senior Subordinated Exchange Note, a holder will
recognize taxable gain or loss equal to the difference between the amount
received in the sale, exchange or retirement (except to the extent the
consideration received is attributable to stated interest not previously taken
into account, which consideration is treated as interest income) and such
holder's adjusted tax basis in the Senior Subordinated Note or Senior
Subordinated Exchange Note, as the case may be. Any gain or loss recognized on
the sale, exchange or retirement of a Senior Subordinated Note or Senior
Subordinated Exchange Note would be capital gain or loss if such Note or
Exchange Note is held as a capital asset and will be long-term capital gain or
loss if the Senior Subordinated Note or Senior Subordinated Exchange Note were
held by the holder for more than one year. For purposes of the foregoing
calculation of capital gain or loss, the applicable holding period for Senior
Subordinated Exchange Notes would begin on the date that such holder was
issued the Senior Subordinated Notes that were subsequently exchanged for such
Senior Subordinated Exchange Notes pursuant to the Exchange Offer.
 
  In certain circumstances, notes issued in connection with the same
transaction or related transactions may be treated as a single note for
purposes of the OID rules. The Borrower has determined that a substantial
portion of each of the Senior Subordinated Notes and the Subordinated Senior
Discount Notes were issued to purchasers not related to the Borrower or to
other purchasers and who did not purchase both Senior Subordinated Notes and
Senior Subordinated Discount Notes in connection with the same transaction or
related transactions. Assuming this is the case, the aggregation rules would
not apply with respect to the Notes or the Exchange Notes.

EXCHANGE OF NOTES FOR EXCHANGE NOTES PURSUANT TO THE EXCHANGE OFFER
 
  An exchange of the Notes for the Exchange Notes pursuant to the Exchange
Offer will not be treated as a taxable exchange for federal income tax
purposes because, other than the fact that the Exchange Notes will be
registered under the Securities Act, upon consummation of the Exchange Offer,
the terms of the Exchange Notes will be identical to the terms of the Notes.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
  Certain noncorporate holders may be subject to backup withholding at a rate
of 31% on payments of principal and interest (including OID) and premium on,
and the proceeds of disposition of, a Note. Backup withholding will apply only
if the holder: (i) fails to furnish its Taxpayer Identification Number ("TIN")
which, for an individual, would be his or her Social Security number; (ii)
furnishes an incorrect TIN; (iii) is notified by the Internal Revenue Service
(the "IRS") that it has failed properly to report payments of interest and
dividends; or (iv) under certain circumstances, fails to certify, under
penalty of perjury, that it has furnished a correct TIN and has not been
notified by the IRS that it is subject to backup withholding for failure to
report interest and dividend payments. Holders of the Notes should consult
their tax advisors regarding their qualification for exemption from backup
withholding and the procedure for obtaining such an exemption, if applicable.
 
  The amount of any backup withholding from a payment to a holder of a Note
will be allowed as a credit against the holder's United States federal income
tax liability and may entitle the holder to a refund, provided that the
required information is furnished to the IRS.
 
OTHER TAX CONSEQUENCES
 
  In addition to the federal income tax considerations described above,
holders of Notes should consider potential state, local, income, franchise,
personal property and other taxation in any state, locality or foreign
jurisdiction and the tax effect of ownership, sale, exchange, or retirement of
Notes or Exchange Notes, or their exchange of Notes for Exchange Notes
pursuant to the Exchange Offer, in any state, locality or foreign
jurisdiction. Prospective purchasers of Notes are advised to consult their own
tax advisors with respect to any state, local or foreign income, franchise,
personal property or other tax consequences arising out of their ownership of
Notes or Exchange Notes.
 
                             PLAN OF DISTRIBUTION
 
  The Exchange Notes are being offered in exchange for Notes pursuant to the
Exchange Offer.
 
  Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a Prospectus in
connection with any resale of such Exchange Notes. The Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer
in connection with resales of Exchange Notes received in exchange for Notes
where such Notes were acquired as a result of market-making activities or
other trading activities. The Borrower has agreed that, for a period of 180
days after the Expiration Date, it will make this Prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
such resale.
 
  Broker-dealers who have acquired Notes directly from TSAT are not permitted
to exchange such Notes in the Exchange Offer.
 
  The Borrower will not receive any proceeds from any sales of the Exchange
Notes by broker-dealers. Exchange Notes received by broker-dealers for their
own account pursuant to the Exchange Offer may be sold from time to time in
one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Notes or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such
 
                                      101
<PAGE>
 
resale may be made directly to purchaser or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from
any such broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker- dealer that resells the Exchange Notes that were received by it for
its own account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commissions or concessions received by
any such persons may be deemed to be underwriting compensation under the
Securities Act. The Letter of Transmittal states that, by acknowledging that
it will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the
Securities Act.
 
  For a period of 180 days after the Expiration Date, the Borrower will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such
documents in the Letter of Transmittal. the Borrower has agreed to pay certain
expenses incident to the Exchange Offer, other than commission or concessions
of any brokers or dealers, and will indemnify the holders of the Exchange
Notes (including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.
 
  By acceptance of the Exchange Offer, each broker-dealer that receives
Exchange Notes for its own account pursuant to the Exchange Offer agrees that,
upon receipt of notice from the Borrower of the happening of any event which
makes any statement in the Prospectus untrue in any material respect or which
requires the making of any changes in the Prospectus in order to make the
statements therein not misleading (which notice the Borrower agree to deliver
promptly to such broker-dealer), such broker-dealer will suspend use of the
Prospectus until the Borrower has amended or supplemented the Prospectus to
correct such misstatement or omission and has furnished copies of the amended
or supplemental Prospectus to such broker-dealer.
 
                          VALIDITY OF EXCHANGE NOTES
 
  The validity of the Exchange Notes will be passed upon for TSAT by Baker &
Botts, L.L.P., New York, N.Y.
