Chief Financial Officer
JAG Media Holdings, Inc.

Boca Raton, FL 33433

Re:   Engagement Letter

Dear Mr. Mazzarisi:

         This letter agreement (this "Agreement") confirms JAG Media Holdings,
Inc. (the "Company") engagement of HPC Capital Management ("HPC") as investment
banker, financial advisor and consultant of the Company and sets forth the terms
and conditions pursuant to which HPC shall perform in said capacity.

         1. Retention Subject to the terms and conditions of this Agreement, the
Company hereby engages HPC to act on behalf of the Company as a non-exclusive
investment banker, financial advisor and consultant commencing on the date
hereof and continuing for a period of 6 months hereafter unless terminated
earlier by either party upon 30-calendar days' written notice (such period
referred to hereinafter as the "Engagement").

          2. Services. During the Engagement and subject to the terms and
conditions herein, HPC agrees to provide financial services to the Company
consisting of: (i) evaluating the Company's requirements for funding growth and
expansion of the Company's operations; (ii) advising the Company as to
alternative modes and sources of financing; (iii) analyzing the impact of
business decisions, policies, and practices on the value of the Company's
business and securities; (iv) increasing the public exposure of the Company
through introductions to institutions, brokers and the investment community; and
(v) bringing to the attention of the Company possible business opportunities and
evaluating business opportunities generally, whether or not HPC or others
originate such opportunities. HPC agrees to devote such time, attention, and
energy as may be necessary to perform the services hereunder. The Company
expressly acknowledges and agrees that nothing herein shall be construed,
however, to require HPC to (i) provide a minimum number of hours of service to
the Company or to limit the right of HPC to perform similar services for the
benefit of persons or entities other than the Company, (ii) commit to purchase
securities of the Company or secure financing on behalf of the Company by third
parties, (iii) ensure that any potential investor(s) introduced to the Company
by HPC will execute final agreements with the Company, or (iv) guaranty the
obligations of any investor(s) introduced to the Company by HPC under any final
agreements with such investor(s).

         3. Remuneration. For undertaking the Engagement and for other good and
valuable consideration, including but not limited to, the substantial benefit
the Company will derive from the ability to announce its relationship with HPC,
the Company agrees as follows:

                  (a) Placement Fees. The Company shall pay to HPC a cash
         placement fee equal to 5% of the total purchase price of the Company's
         securities sold, including all amounts placed in an escrow account or
         payable in the future (including future issuances resulting from anti
         dilution provisions) and all amounts paid or payable upon exercise,
         conversion or exchange of such securities received or receivable
         directly by the Company ("Aggregate Consideration") in any placement of
         the Company's securities in connection with HPC's efforts hereunder.
         Such consideration paid in cash shall be paid directly to HPC out of
         escrow, as and when such consideration is paid to the Company.
         Notwithstanding the foregoing, in connection with the exercise within
         one (1) year of closing of the transaction of any investor warrants
         issued in connection with a placement of the securities in connection
         with HPC's efforts hereunder, HPC's placement fee shall be reduced to
         4% of the cash proceeds (0% in the case of an exercise after one (1)
         year of closing of the transaction) and shall be paid to HPC.

                  (b) Warrants. On each closing date on which Aggregate
         Consideration is paid or becomes payable, the Company shall issue to
         HPC 30,000 warrants (the "Warrants") per $1 million raised by HPC. The
         exercise price of the Warrants shall equal the lower price (to any
         investor(s)) at which any common equity of the Company is or may be
         sold in such placement or upon the conversion, exercise or exchange of
         such securities. The Warrants shall be exercisable immediately after
         the date of issuance, and shall expire 5 years after the date of
         issuance, unless otherwise extended by the Company. The Warrants shall
         include a cashless exercise provision and will be non-redeemable and
         provide for automatic exercise upon expiration. The Warrants shall be
         transferable, subject only to the securities laws, by the holders
         thereof.

                   (c) Mergers and Acquisitions. The Company agrees that if HPC,
         directly or indirectly, introduces the Company, during the term of this
         Agreement, to any person or entity that becomes a party to a merger,
         acquisition, joint venture or other similar transaction with the
         Company or any affiliate thereof, then the Company shall pay to HPC a
         fee calculated as a percentage of the Transaction Value (as defined
         herein) in accordance with the following scale:

                                                             Confidential Page 2

                    o      6% on the first           $ 1,000,000
                    o      5% on the amount from     $ 1,000,001 to $ 3,000,000
                    o      4% on the amount from     $ 3,000,001 to $ 5,000,000
                    o      3% on the amount from     $ 5,000,001 to $ 7,000,000
                    o      2% on the amount from     $ 7,000,001 to $9,000,000
                    o      1% on the amount above $ 9,000,001

         The fee shall be payable to HPC in the same medium (i.e., cash or
         stock) and in the same ratio of both as the consideration for the
         transaction.

                  "Transaction Value" shall mean the aggregate value of all
         cash, securities, notes, debentures purchase options, consideration
         paid for assets owned by majority owned subsidiaries of the Company or
         entities in any business relationship which are used in or are
         potentially useful in the Company 's business; the total value of
         liabilities avoided by the Company or assumed by the acquirer; the
         total value of all liabilities on the Company's balance sheet that are
         transferred to the acquirer of the stock of the Company in a stock
         transaction and any other tangible net benefit to the Company, its
         shareholders or directed beneficiaries and other property and valuable
         consideration of every kind either (i) transferred to the Company and
         its affiliates in connection with any transaction involving any
         investment , loan or any other equity or debt financing for, or
         acquisition of, the Company or any affiliate thereof, or in connection
         with an acquisition of equity or assets thereof or (ii) transferred by
         the Company and its affiliates in any transaction involving an
         investment in or acquisition of any third party, or acquisition of the
         equity or assets thereof, by the Company or any affiliate thereof or
         (iii) transferred or otherwise contributed by all parties to enter into
         any joint venture or similar joint enterprise or undertaking with the
         Company or any affiliate thereof. The aggregate value of the
         consideration shall be the aggregate fair market value thereof as
         determined jointly by HPC and the Company, or, if the parties cannot
         agree, by an independent appraiser jointly selected by HPC and the
         Company. The parties hereby agree that any share of the Company's Class
         A common stock shall be valued at its closing bid price on the OTC
         Bulletin Board (as reported by Bloomberg L.P.) as of the date the
         consideration for the transaction is established.

                  (d) Tail Period. The Company shall and shall have cause its
         affiliates to pay HPC all compensation described in this Section 3 with
         respect to all financing and merger and acquisition candidates at any
         time prior to the expiration of 1 year after the Termination Date (the
         "Tail Period") if such candidates were identified to the Company by HPC
         during the Engagement Period and HPC provided written notification to
         the Company of the introduction.
