                     AMENDED AND RESTATED CREDIT AGREEMENT


          THIS AMENDED AND RESTATED CREDIT AGREEMENT is dated as of February 19,
1997 and is between TCI COMMUNICATIONS, INC., a Delaware corporation ("TCIC"),
                                                                       ----   
and TCI SATELLITE ENTERTAINMENT, INC., a Delaware corporation ("Satellite
                                                                ---------
Company").
-------   

RECITALS:
-------- 

          A.   On December 4, 1996, Satellite Company and TCIC executed a Credit
Agreement, dated as of December 4, 1996 (the "TCIC Credit Agreement").  TCIC and
                                              ---------------------             
Satellite Company entered into the TCIC Credit Agreement for the purpose of
providing to Satellite Company a $250,000,000 term loan and a $500,000,000
revolving loan facility.

          B.   On December 31, 1996, Satellite Company entered into a Credit
Agreement (as amended by a First Amendment to Bank Credit Agreement, dated
February 19, 1997, and as thereafter amended or modified from time to time, the
"Bank Credit Agreement") among The Bank of Nova Scotia, as Administrative Agent,
 ---------------------                                                          
Nationsbank of Texas, N.A., as the Syndication Agent, Credit Lyonnais New York
Branch as the Documentation Agent, the financial institutions named as lenders
therein, and The Bank of Nova Scotia, Credit Lyonnais New York Branch and
Nationsbank of Texas, as the Arranging Agents.  Proceeds from the initial
borrowing under the Bank Credit Agreement were used to permanently retire the
$250,000,000 term loan under the TCIC Credit Agreement.

          C.   Section 7.1.12 of the Bank Credit Agreement requires Satellite
Company to enter into an amendment to the TCIC Credit Agreement to provide for,
among other things, limitations on the availability of the Revolving Loans (as
defined in Article I hereof).

          D.   Satellite Company proposes to issue in a private transaction
$475,000,000 aggregate principal amount at maturity of senior subordinated notes
due 2007 (of which approximately $275,000,000 aggregate principal face amount
will be discount notes, resulting in approximately $150,000,000 gross proceeds
to Satellite Company), which notes Satellite Company is required to offer to
make an offer to repurchase in full if the GE-2 satellite (as defined in the
Indentures (as defined in Article I hereof)) does not meet certain operating
criteria.  In such event, the escrowed net proceeds of the offering and sale of
such notes would be insufficient to pay the full purchase price, and TCIC
desires to agree to make loans to Satellite Company to fund such deficiency in
an amount not to exceed the Note Offering Expenses (as defined in Article I
hereof).  The Purchase Agreement dated February 14, 
<PAGE>
 
1997 between Satellite Company and the Initial Purchasers (as defined in the
Indentures) requires that Satellite Company and TCIC enter into an amendment to
the TCIC Credit Agreement to, among other things, provide for the making of
loans under this Amended and Restated Credit Agreement for the aforementioned
purpose.

          E.   In order to satisfy the requirements of section 7.1.12 of the
Bank Credit Agreement and the requirements of such Purchase Agreement and to
provide for loans to fund such deficiency, the parties are entering into the
following amendment and restatement of the TCIC Credit Agreement.

                              THE REVOLVING LOANS

          SECTION 2.01.  Revolving Loans.
                         --------------- 

          (a)  Upon the terms and subject to the conditions set forth in this
Agreement, TCIC agrees to originate the revolving loans on a revolving credit
basis to Satellite Company (the "Revolving Loans"), from time to time, from the
                                 ---------------                               
date of this Agreement until the Revolving Loan Commitment Termination Date, at
such time and in such amounts as Satellite Company shall request, in an
aggregate principal amount at any time outstanding not in excess of the
Revolving Loan Commitment.  Upon the terms and subject to the conditions set
forth in this Agreement, Satellite Company (or the Administrative Agent if an
Event of Default under the Bank Credit Agreement has occurred and is continuing)
may borrow, repay and reborrow funds from TCIC.  Anything contained herein to
the contrary notwithstanding, if Satellite Company issues and sells Senior
Subordinated Notes and/or Senior Sub Discount Notes resulting in aggregate
gross proceeds of at least $350,000,000, then the Revolving Loans will not be
available hereunder unless, prior to the Revolving Loan Commitment Termination
Date, Satellite Company makes an Offer to Purchase pursuant to Section 4.19 of
the Indentures all of the Senior Subordinated Notes and all of the Senior Sub
Discount Notes, as provided in the Indentures, and, in such event, the
Revolving Loans shall only be available in an aggregate principal amount up to
$50,000,000 until Satellite Company shall have purchased all the notes tendered
pursuant to such Offer to Purchase.

          (b)  In order to effect a borrowing under the Revolving Loan
Commitment, Satellite Company (or the Administrative Agent if an Event of
Default under the Bank Credit Agreement has occurred and is continuing) shall
give TCIC irrevocable written notice not less than three Business Days before a
requested borrowing.  Such notice shall in each case be signed by an authorized
officer and shall refer to this Agreement and specify:  (i) the amount of the
requested borrowing under this Agreement, (ii) the date (which shall be a
Business Day) on which Satellite Company is to receive the proceeds of such
borrowing, (iii) whether the proceeds of the bor-

                                      -6-
<PAGE>
 
rowing will be used for the Specified Use and the amount of the borrowing for
such Specified Use, and (iv) that all conditions to such borrowing set forth in
Article IV of this Agreement have been satisfied. Satellite Company shall be
deemed to be making, as of the date of the delivery of the borrowing notice, the
representations and warranties contained in Article III of this Agreement by
the act of delivering such borrowing notice to TCIC.

          (c)  The Revolving Loans made by TCIC shall be evidenced by the Notes
(which shall be substantially in the form of Exhibit A hereto) duly executed on
                                             ---------                         
behalf of Satellite Company.  TCIC shall endorse on the schedule attached to
the Notes, or otherwise record in its internal records, an appropriate notation
evidencing the date and amount of each Revolving Loan, each payment and
prepayment of the principal amount of any Revolving Loan and other information
provided for on such schedule; provided, however, that the failure of TCIC to
                               --------  -------                             
make such a notation or any error in such notation shall not affect the
obligation of Satellite Company to repay the Revolving Loans in accordance with
the terms of this Agreement and the Notes.

          SECTION 2.02.  Interest on the Revolving Loans.
                         ------------------------------- 

          (a)  Subject to Section 2.02(d) below, the principal amount of each
Revolving Loan shall bear interest at a rate per annum (computed on the basis of
the actual number of days elapsed over a year of 360 days) equal to 10%.
Accrued interest shall compound semi-annually until paid.

          (b)  Interest on each Revolving Loan shall be due and payable on the
date the principal amount of such Revolving Loan is prepaid, upon acceleration
of such Revolving Loan, or upon the Maturity Date.

          (c)  If Satellite Company shall default in the payment of the
principal of, or interest on any Revolving Loan, or on any other amount
becoming due hereunder, by scheduled maturity or acceleration, Satellite Company
shall, on demand from time to time from TCIC, pay interest, to the extent
permitted by law, on such defaulted amount up to the date of actual payment
(after as well as before judgment) at a rate per annum (computed on the basis of
the actual number of days elapsed over a year of 360 days) equal to the interest
rate then in effect pursuant to Section 2.02(a) above plus 2%.

          (d)  All agreements between Satellite Company and TCIC are expressly
limited so that in no contingency or event whatsoever shall the interest paid or
agreed to be paid to TCIC for the use, forbearance, or detention of the
indebtedness evidenced by the Notes exceed 

                                      -7-
<PAGE>
 
the maximum rate permissible under applicable law (the "Maximum Rate"). If from
                                                        ------------
any circumstance TCIC should ever receive an amount which would represent
interest in excess of the Maximum Rate, such amount as would be excessive
interest shall be applied to the reduction of the principal amount owing under
the Notes and not to the payment of interest. In determining whether the
interest paid or payable, under any contingency, exceeds such Maximum Rate,
Satellite Company and TCIC shall to the maximum extent permitted by applicable
law: (i) characterize any non-principal payment as an expense, fee, or premium
rather than as interest; (ii) exclude voluntary prepayments and the effects
thereof; (iii) amortize, prorate, al locate, and spread the total amount of
interest throughout the full term of the Notes so that the actual rate of such
interest does not exceed such Maximum Rate; or (iv) allocate interest between
portions of the debt evidenced hereby so that no portion of such debt shall bear
interest at a rate greater than such Maximum Rate. For purposes of the Notes,

but is later cured or waived, Satellite Company shall prepay all amounts due
under the Revolving Loans as soon as no Event of Default under the Bank Credit
Agreement exists and shall prepay to the extent of any unused Available
Commitment Amount. Satellite Company's obligation to prepay under the
conditions of this section 2.03(c) shall continue after the Satellite Event Date

notice (except for the notice required by section 6.01 of the Agreement) of any
kind whatsoever.  The nonexercise by the holder of any of its rights hereunder

to pay hereunder, will pay a reasonable sum for attorneys' fees incurred by the
holder hereof in connection with such action or suit and all other costs of
collection.

entitled to the benefits, and is subject to the terms, set forth therein, which,
among other things, contains provisions for the acceleration of the maturity
hereof upon the happening of certain events, for optional and mandatory
prepayment of the principal hereof prior to the maturity hereof and for the
amendment or waiver of certain provisions of the Agreement, all upon the terms
and conditions therein specified.  This Note is subordinated to the Bank
