Fund III, L.P., a Delaware limited partnership ("HMTF"), and HM3 Coinvestors,

                                    RECITALS:

         A. Pursuant to the Purchase Agreement (the "Purchase Agreement") dated
as of the date hereof among SA Television Investments, Inc. ("SA Television"),
HMTF and HM3, HMTF and HM3, upon the satisfaction of the conditions contained
therein, have agreed to acquire from SA Television (i) 250,000 shares (together
with any and all shares of Preferred Stock (as defined below) issued or issuable
in respect of such shares as in-kind dividends, the "Shares") of the 14%
Redeemable Preferred Stock, par value $0.01 per share (the "Preferred Stock"),
of STC Broadcasting, Inc., a Delaware corporation and subsidiary of Sunrise
Television Corp., a Delaware corporation ("Sunrise"), (ii) a Senior Subordinated
Promissory Note, dated December 30, 1999, in the original principal amount of

         B. The Buyer desires to purchase from Sellers, and Sellers desire to
sell to the Buyer, the Shares and Notes pursuant to the terms and conditions
hereof.

         NOW, THEREFORE, in consideration of the premises and of the mutual
covenants contained herein, the parties hereto agree as follows:

         1. Purchase and Sale of Shares and Notes. Subject to the terms and
conditions hereof, Sellers severally agree to sell, and the Buyer shall
purchase, the Shares and the Notes.

         2. Purchase Price; Exchange.

                  (a) The purchase price per Share shall be $100.00, plus
         accumulated and unpaid dividends to, but not including, the Closing
         Date (as defined in Section 4)(such aggregate price being referred to
         herein as the "Shares Purchase Price").

                  (b) The purchase price for the Notes shall be the principal
         balance of the Notes then outstanding on the Closing Date, plus accrued
         and unpaid interest to, but not including, the Closing Date (together
         with the Shares Purchase Price, the "Purchase Price").

                  (c) At the Closing (as defined in Section 4), the Buyer shall
         issue to HMTF and HM3, the number of shares (rounded to the nearest
         whole share) of its Class B Common Stock, par value $0.01 per share, as
         is determined by dividing the Purchase Price payable to each of HMTF
         and HM3 by the Fair Market Value of a share of Class A Common Stock,
         par value $0.01 per share, of the Buyer. For purposes hereof, "Fair
         Market Value" shall mean (x) in the event that LIN has consummated an
         initial public offering of its Class A Common Stock (an "IPO"), the
         public offering price per share, less underwriting discounts and
         commissions, of such a share in the IPO and (y) in the event that LIN
         has not consummated an initial public offering of its Class A Common
         Stock, unless otherwise determined by mutual agreement of the Buyer and
         Sellers, the midpoint of the range of the proposed public offering
         price per share of such a share in the

         IPO, less the proposed underwriting discount and commission, as set
         forth in the latest prospectus relating to the IPO.

         3. Other Actions at the Closing. At the Closing: (a) Sellers shall
deliver to the Buyer certificates representing the Shares duly endorsed to the
Buyer or accompanied by stock powers duly executed by Sellers, in form and
substance reasonably satisfactory to the Buyer, and (b) Sellers shall deliver to
the Buyer the Notes duly endorsed to the Buyer.

         4. Closing. Subject to the terms and conditions hereof, the
consummation of the transactions contemplated in this Agreement (the "Closing")
shall occur at the offices of Weil, Gotshal & Manges LLP, 767 Fifth Avenue, New
York, New York 10153, at 9:00 a.m., on the date (the "Closing Date") of the
consummation of the merger contemplated by the STC/LIN Merger Agreement (as
defined in Section 8(a)(iv)), unless otherwise agreed to by Buyer and Sellers.
