     5.  Section 1.14 of the Shareholders Agreement is hereby restated to read
in its entirety as follows:

         "1.14  Lock-Up Provision.  If requested by the Company and an
                -----------------                                     
     underwriter of equity securities of the Company, no Holder shall sell or
     otherwise transfer or dispose of any Restricted Securities (without the
     written consent of such underwriters and other than those securities
     included in the registration) during the up to one hundred eighty- (180-)
     day period following the effective date of a registration statement filed
     in connection with the public offering of the Company's securities,
     provided that all officers and directors enter into similar agreements. The
     obligations described in this

                                      -2-

 
     Section 1.14 shall not apply to a registration relating solely to employee
     benefit plans on Form S-1 or Form S-8 or similar form that may be
     promulgated in the future. The Company may impose stop-transfer
     instructions with respect to the securities subject to the foregoing
     restriction until the end of the one hundred eighty- (180-) day period."

     6.  Section 2.2 of the Shareholders Agreement is hereby restated to read
in its entirety as follows:

         "2.2  Election of Directors.  Each time the Shareholders shall meet,
               ---------------------                                         
     or act by written consent in lieu of acting at a meeting, for the purpose
     of electing one or more directors of the Company, each Shareholder agrees
     to vote its Shares (i) for the election of three (3) representatives of
     Sunset Partners (hereinafter defined as Sunset Partners, L.P., Sunset
     Partners II, L.P., and Sunset Partners III, L.P. collectively), (ii) for
     the election of one (1) representative of Pomona Capital and its affiliated
     partnerships, and (iii) in the event that Equity-Linked Investors II ("ELI-
     II") shall become entitled to elect a representative to the Board of
     Directors pursuant to Section 3.2 of the Series D Preferred Stock Investors
     Rights Agreement (the "Series D Rights Agreement") of even date herewith,
     for the election of one (1) representative of ELI II; provided, however,
     that each Shareholder also agrees to vote its shares for the election of
     two (2) representatives of the holders of Series C Preferred Stock as two
     additional directors (resulting in a board of nine (9) directors) if the
     Company fails to meet any one or more of the following three criteria for
     the period (the "Relevant Period") commencing on the date hereof and ending
     December 31, 1996:

         (a) average gross revenues per room of not less than $30 per month for
     the Relevant Period,

         (b) at least 100,000 rooms installed by the end of the Relevant
     Period, and

         (c) a capital cost per room (including the cost of interactive
     shopping, but excluding the cost of televisions) of not more than $600
     based on rooms added during the Relevant Period.

     The obligation assumed by each Shareholder hereunder to vote its Shares as
     set forth above shall be deemed to be a right coupled with an interest in
     favor of each other Shareholder, and each other Shareholder may, by acting
     through a person designated by Shareholders holding a majority of the
     Shares subject to this provision, vote such Shareholder's Shares by proxy.
     The parties to this Restated Shareholders' Agreement shall vote their
     Shares to maintain a board of seven (7) directors, unless either (i) one or
     more of the foregoing three criteria are not met during the Relevant Period
     or (ii) ELI-II shall become entitled to elect a representative to the Board
     of Directors pursuant to the Series D Rights Agreement. In the case of (i)
     above, the parties hereto

                                      -3-

 
     shall vote their Shares to increase the board to nine (9) directors with
     the additional two (2) directors nominated and elected as set forth above.
     In the case of (ii) above, the parties hereto shall vote their shares to
     increase the board by one director and to elect the representative of ELI-
     II to fill such position as set forth above and in the Series D Rights
     Agreement."

     7.  Section 2.4 of the Shareholders Agreement is hereby restated to read
in its entirety as follows:

         "2.4  Effectiveness; Termination.  This Section 2 shall become
               --------------------------                              
     effective on the date hereof.  This Section 2 shall terminate upon the
     closing of the Company's first offering of voting equity securities to the
     public pursuant to a registration statement filed with the Securities and
     Exchange Commission or the equivalent securities authority or agency in any
     foreign jurisdiction.  If Sunset Partners holds less than fifty percent
     (50%) of the shares of Series C Preferred Stock it holds on the effective
     date of this Restated Shareholders' Agreement, then each Shareholder agrees
     to vote its shares for the election of two (2) representatives of Sunset
     Partners.  If Sunset Partners holds less than twenty-five (25%) of the
     shares of Series C Preferred Stock it holds on the effective date of this
     Restated Shareholders' Agreement, then each Shareholder agrees to vote its
     shares for the election of one (1) representative of Sunset Partners.  With
     respect to Sunset Partners, the provisions of this Section 2 shall
     terminate when Sunset Partners holds less than ten percent (10%) of the
     shares of Series C Preferred Stock it holds on the effective date of this
     Restated Shareholders' Agreement.  With respect to Pomona Capital, the
     provisions of this Section 2 shall terminate when Pomona Capital and its
     affiliated partnerships hold less than fifty percent (50%) of the shares of
     Series C Preferred Stock such entities hold on the effective date of this
     Restated Shareholders' Agreement.  With respect to ELI-II, the provisions
     of this Section 2 shall terminate upon the termination of ELI-II's right to
     elect a member of the Company's Board of Directors pursuant to the Series D
     Rights Agreement."

     8.  The New Series D Purchasers shall be deemed "Rights Holders" for
purposes of Section 3 of the Shareholders' Agreement.

     9.  Section 3.3(e) and 3.3(f) are hereby deleted, and Section 3.3 is
hereby amended to include the following subsections to Section 3.3:

               "(e)  securities issued to dealers, trade vendors, sales
     representatives, equipment lessors, commercial lenders (or their
     guarantors) or joint venturers of the Company on terms approved by the
     Board of Directors;

               (f)   securities issued to holders of the Company's Senior
     Secured Notes due 2000 in consideration of such holder's amendment or
     waiver at the Company's request of provisions of the Note Agreement dated
     August 15, 1995; and


                                      -4-

 
               (g) securities issued to effect any stock split or stock dividend
     by the Company."

     10. The New Series D Purchasers shall be deemed "Remaining Holders" for
purposes of Section 4 of the Shareholders' Agreement.

     11. Section 10.8 of the Shareholders Agreement is hereby restated to read
in its entirety as follows:

         "10.8  Entire Agreement; Amendment and Waiver.  This Restated
                --------------------------------------                
     Shareholders' Agreement and the other documents delivered pursuant hereto
     constitute the full and entire understanding and agreement between the
     parties with regard to the subject matters hereof and thereof.  Except as
     provided in Section 1.12, any term of this Restated Shareholders' Agreement
     may be amended and the observance of any term hereof may be waived (either
     prospectively or retroactively and either generally or in a particular
     instance) only with the written consent of more than seventy-five percent
     (75%) in interest of the Holders and the written consent of the Company.
     Any amendment or waiver effected in accordance with this Section 10.8 shall
     be binding upon each Holder and the Company.  In addition, the Company may
     waive performance of any obligation owing to it, as to some or all of the
     Holders, or agree to accept alternatives to such performance, without
     obtaining the consent of any Holder."

     12. Each of the parties hereto acknowledges that the Company may sell and
issue additional shares of the Series D Preferred subsequent to the date hereof
and prior to May 31, 1996.  Each of the parties hereto agrees that each such
purchaser shall become a party to this First Amendment and the Shareholders'
Agreement without further amendment hereof or thereof, and each such purchaser
shall be deemed a New Series D Purchaser for all purposes hereunder upon
execution of a counterpart signature page to this First Amendment.  The Company
shall amend Schedule A attached hereto to reflect the addition of such
            ----------                                                
subsequent New Series D Purchasers and shall deliver a copy of such revised
                                                                           
Schedule A to each party hereto.  In no event shall the number of outstanding

shares of Series D Preferred exceed 3,142,858 without amendment of the Company's
Amended and Restated Articles of Incorporation authorizing such additional
shares of Series D Preferred.

     13. Except as expressly set forth in this First Amendment, the
Shareholders' Agreement shall continue in full force and effect in accordance
with its terms.

     14. This First Amendment may be executed in one or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute
one and the same instrument.  This Amendment shall be governed by and construed
and enforced in accordance with the laws of the State of California as applied
to agreements between California residents entered into and to be performed
entirely within California.
