                            STOCK PURCHASE AGREEMENT

                  First Amendment, dated as of December 31, 1996 (the
"Amendment"), to Stock Purchase Agreement, dated as of May 25, 1995 (the
"Neovision Purchase Agreement"), between ITI Media Group N.V., a corporation
organized under the laws of the Netherlands Antilles (the "Seller"), and CME
Media Enterprises B.V., a corporation organized under the laws of the
Netherlands (the "Buyer").

                                    RECITALS

                  A. The Seller and the Buyer have executed and delivered the
Neovision Purchase Agreement and have completed the First Closing thereunder.

                  B. The Buyer has made two loans (the "Loans") to the Seller
in the aggregate principal amount, taken together, of US$ 4,355,000.

                  C. The Seller and the Buyer desire to amend their agreement
relating to the Second Closing under the Neovision Purchase Agreement and to
cause all or a portion of the funds delivered by the Buyer to the Seller in
connection with the Second Closing to be applied to the repayment in full of
the principal amount of the Loans, together with accrued and unpaid interest
thereon to the date of such repayment.

                  In consideration of the foregoing, the Seller and the Buyer
agree as follows:

                  1. Capitalized terms used in this Amendment without
definition shall have the meanings given to them in the Neovision Purchase
Agreement.

                  2. Section 1.2 of Article I of the Neovision Purchase
Agreement is hereby amended in its entirety to read as follows:

         "1.2 Second Closing. At the second closing (the "Second Closing"),
         Seller shall sell and transfer to Buyer such number of Shares as shall
         constitute 24.5% of the aggregate outstanding Shares, and Buyer shall
         purchase such number of Shares by, at its election, either (i) paying
         US$ 5 million (the "Second Purchase Price") in immediately available
         funds to the Seller, or as instructed by the Seller, or (ii) applying
         a portion (the "Loan Amount") of the Second Purchase Price to the
         repayment in full of the principal amount of loans extended by the
         Buyer to the Seller, pursuant to agreements between the Buyer and the
         Seller dated September 10, 1996 and November 7, 1996 (the "Loan
         Agreements"), and the payment in full of accrued and unpaid interest
         thereon up to the date of the Second Closing, and, subject to the
         condition contained in Section 2.3, paying an amount equal to the
         excess of (x) the Second Purchase Price over (y) the Loan Amount in
         immediately available funds to the Seller, or as instructed by the
         Seller. In the event that the Buyer elects to apply the Loan Amount
         towards payment of the Second Purchase Price, the Buyer shall also

         return to the Seller, or destroy, any promissory note or notes
         relating to loans extended pursuant to the Loan Agreements and shall
         provide the Seller with such receipt, certificate or other document
         executed by the Buyer, indicating the release of the Seller from its
         obligations under the Loan Agreements, as the Seller may reasonably
         request."

                  3. Section 1.3 of Article I of the Neovision Purchase
Agreement is hereby amended by adding the following sentence to the end
thereof:

         "In the case of the Second Closing, Buyer and Seller shall cause such
         notarial deed applicable to the Shares purchased by the Buyer at the
         Second Closing to be executed on Tuesday, December 31, 1996."

                  4. Section 2.2 of Article II of the Neovision Purchase
Agreement is hereby amended by (i) substituting the word "condition" for the
word "conditions" in the fourth line thereof, (ii) substituting a period for
the semi-colon in the fifth line of paragraph (a) thereof, (iii) deleting the
word "and" at the end of paragraph (a) thereof, and (iv) deleting paragraph (b)
thereof in its entirety.

                  5. Article II of the Neovision Purchase Agreement is hereby
amended by adding the following section immediately following the end thereof:

                           "2.3 Conditions Subsequent to Second Closing. The
         obligation of the Buyer to pay any cash portion of the Second Purchase
         Price is conditioned on the satisfaction or waiver, at or prior to the
         date of payment thereof, of the following conditions:

                           (a) the representations and warranties of Seller
                  contained in this Agreement shall be true and correct in all
                  material respects as of the date of payment thereof and
                  Seller shall have delivered to Buyer a certificate dated such
                  date and to such effect; and

                           (b) ITI TV and CME shall have made the capital
                  contributions required under Section 4.2 of the TVN
                  Shareholder Agreement (the "Second TVN Closing").

                  6. Article VI of the Neovision Purchase Agreement is hereby
amended by adding the following section immediately following the end thereof:

                           "6.4 Additional Buyer Put. In the event that (a) the
         Second TVN Closing does not occur on or before the second anniversary
         of the date of the First Closing; and (b) Buyer has exercised its
         rights under Section 8.1 of the TVN Shareholder Agreement; then Buyer
         shall have the right, exercisable at any time during the 180-day
         period following such second anniversary upon written notice (the
         "Additional Put Notice") to Seller (which will be deemed validly given
         if included as a part of the Put Notice), to cause Seller to purchase
         all of the Shares purchased at the Second Closing at a purchase price,
         net of applicable Dutch taxes, if any (the "Additional Put Price"),
         equal to the sum of (i) US$ 5,000,000, less (ii) the amount of any

         cash portion of the Second Closing Price remaining unpaid by the Buyer
         as of the date of payment of the Additional Put Price, plus (iii)
         interest on such aggregate amount at a rate per annum equal to 6% from
         the date of the Second Closing to the date of payment of the
         Additional Put Price. Seller shall pay the Additional Put Price in
         immediately available funds to Buyer (or as directed by it) on the
         date specified in the Additional Put Notice (which shall be not sooner
         than five business days from the date of such notice)."

                  7. Except as amended, modified or waived herein, the
Neovision Purchase Agreement shall remain in full force and effect in
accordance with its terms.

                  8. This Amendment shall become effective when duly executed
and delivered by the Seller and the Buyer.

                  9. This Amendment may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one and the same instrument.

                  10. This Amendment shall be governed by and construed in
accordance with the laws of the State of New York, without giving effect to the
conflict of law rules thereof.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Amendment to be executed and delivered as of the date first above written.
