hereof, in whole or in part, by the surrender of this Warrant (with the notice
of exercise provision contained on the last page hereof duly executed) at the

        4. RECLASSIFICATION OF STOCK. In the event of the reclassification of
the Stock, the Company agrees that the Warrant Holder will be entitled to the
same rights to acquire such reclassified Stock ("New Stock") as those rights

herein. All of the terms and conditions of this Warrant shall apply equally to
the purchase or acquisition of any New Stock.

        5. FRACTIONAL SHARES. No fractional shares of Stock will be issued in

        6. COMPLIANCE WITH SECURITIES LAWS; DISPOSITION OF WARRANT AND SHARES OF
COMMON STOCK.

               (a) Compliance With Securities Laws. The holder of this Warrant,
by acceptance hereof, acknowledges that this Warrant and the shares of Stock to
be issued upon exercise hereof are being acquired for investment purposes only
and that such Holder will not offer, sell or otherwise dispose of this Warrant
or any shares of Stock to be issued upon exercise hereof except under
circumstances which will not result in a violation of the Securities Act of
1933, as amended (the "Act"), or any state securities laws. Upon exercise of
this Warrant, the holder hereof shall, if requested by the Company, confirm in
writing, in a form satisfactory to the Company, that the shares of Stock so
purchased are being acquired for investment purposes only and not with a view
toward distribution or resale. This Warrant and all shares of Stock issued upon
exercise of this Warrant shall be stamped or imprinted with a legend in
substantially the following form (in addition to any legend required by state
securities laws):

               THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR
               INVESTMENT PURPOSES ONLY AND HAVE NOT BEEN REGISTERED UNDER THE
               SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH SECURITIES
               AND ANY SECURITIES OR SHARES ISSUED HEREUNDER MAY NOT BE SOLD OR
               TRANSFERRED UNLESS A REGISTRATION STATEMENT UNDER THE ACT IS IN
               EFFECT AS TO SUCH SALE OR TRANSFER, OR IN THE OPINION OF COUNSEL
               ACCEPTABLE TO THE COMPANY, SUCH REGISTRATION IS UNNECESSARY, OR
               AN EXCEPTION THEREFROM IS AVAILABLE UNDER THE ACT.

               (b) Transfer of Warrant or Shares of Stock. Each certificate
representing the shares of Stock issued hereunder shall bear a legend as to the
restrictions on transferability in order to insure compliance with applicable
securities laws unless, in the opinion of counsel for the Company, such legends
are not required. The Company may issue stop transfer instructions to its
transfer agent in connection with such restrictions.

        7. RIGHTS OF SHAREHOLDERS. This Warrant shall not entitle the Holder to
be deemed the holder of stock or any other securities of the Company which may
be issuable on the exercise hereof for any purpose, nor shall anything contained
herein be construed to confer upon the holder of this Warrant, as such, any of
the rights of a shareholder of the Company or any right to vote for the election
of directors or upon any matter submitted to shareholders at any meeting
thereof, or to give or withhold consent to any corporate action (whether upon
any recapitalization, issuance of stock, reclassification of stock,
consolidation, merger, conveyance, or otherwise) or to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until the
Warrant shall have been exercised and the certificates representing the Shares
purchasable upon the exercise hereof shall have been issued, as provided herein.

        8.     CONTINUING REPURCHASE RIGHT.

               a. Continuing Repurchase Right. The Company is hereby granted the
right (the "Repurchase Right"), exercisable at any time during the period from
March 1, 2000 until September 30, 2000, to repurchase at the Exercise Price all
or (at the discretion of the Company and with the consent of the Warrant Holder)

Shares") in which the Warrant Holder

<PAGE>   3

has not acquired a vested interest in accordance with the vesting provisions of
this Section 8(c) (such shares to be hereinafter called the "Unvested Shares").
Additionally, as April 1, 2000, this Warrant shall cease to be exercisable for
any and all Unvested Shares.

               b. Exercise. The Continuing Repurchase Right shall be exercisable
by written notice delivered to the Warrant Holder. The notice shall indicate the
number of Unvested Shares to be repurchased and the date on which the repurchase
is to be effected, such date to be not more than thirty (30) days after the date
of notice. Warrant Holder shall, prior to the close of business on the date
specified for the repurchase, deliver to the Secretary of the Company the
certificates representing the Unvested Shares to be repurchased, each
certificate to be properly endorsed for transfer. The Company shall,
concurrently with the receipt of such stock certificates, pay to Warrant Holder
in cash or cash equivalent (including the cancellation of any purchase-money
indebtedness), an amount equal to the Exercise Price previously paid for the
Unvested Shares which are to be repurchased.

               c. Termination of the Repurchase Right. The Repurchase Right
shall terminate with respect to any Unvested Shares for which it is not timely
exercised under this Section 8(b). In addition, the Repurchase Right shall
terminate, and cease to be exercisable, with respect to the number of shares
calculated as follows: the product of (i) 3, and (ii) the aggregate amount of
investment received by the Company from investors first introduced to the
Company by the Warrant Holder, as of the close of business on January 15, 2000.

        WHEREAS, Heartbeat's management is experienced in the production of
thirty minute television shows that feature businesses in a news magazine style
and is desirous of producing such a show that would feature HyperBaric and be
entitled Heartbeat of America, and

        WHEREAS, HyperBaric wishes to be featured on said television show and
"Breaking News" marketing videos described below and participate in same under

NOW, THEREFORE, THE PARTIES DO HEREBY AGREE AS FOLLOWS:

1.      THE PRODUCTION

               Heartbeat shall write, direct, and produce a professional
thirty-minute television show entitled Heartbeat of America (the "Show"). The
Show will be produced in a news magazine format including anchors and reports,
and will feature HyperBaric. HyperBaric will travel at its own expense to
Heartbeat's television studio in Southern California for a "breaking news"
interview taped on Heartbeat's news set and conducted by one or more of
Heartbeat's anchors. HyperBaric will arrive the day before the shoot for a
script conference. The date for this studio interview will be set at a time
convenient for both Heartbeat and HyperBaric. Heartbeat, at its option, may
repeat portions of the show for the benefit of the viewers who tune in late. The
script will be completed in approximately two months from the date of this
Agreement and the Show and Videos described in Paragraph 5 will be completed
approximately two months after the script is completed. Heartbeat shall use best
efforts to incorporate HyperBaric's comments into the script.

2.      GUARANTEED AIR TIME

        Heartbeat guarantees that the Show will be aired one time nationally via
cable or satellite within three months after completion of Show, the exact date,
time and channel to be determined by Heartbeat.

3.      SALES RIGHTS

        The thirty-minute television Show shall be the property of Heartbeat.
Heartbeat and HyperBaric shall split equally any revenues derived from the sales
of the Show for a period of ten years from the date of this Agreement.
HyperBaric shall also have the unlimited right to use and duplicate the tape of
the Show without any payment of royalty or license for its use in marketing and
promotion as long as the tape is not sold commercially or used for television
broadcast purposes.

4.      SCRIPT

        HyperBaric shall provide Heartbeat with as much information as
available, written and verbal, on HyperBaric's background, history, current
operations, future plans, and all other information as reasonably required by
Heartbeat. Heartbeat will have final script rights with regard to its anchors
and all questions for HyperBaric will be prepared by both Heartbeat and
HyperBaric.

videos, (approximately five minutes, ten minutes and fifteen minutes in length)
(the "Videos") and turn over to HyperBaric a Beta-Master for each such video
plus 5 VHS copies of each plus 200 Heartbeat of America "breaking news" labels
for the video cassettes. HyperBaric shall have the perpetual rights to make
unlimited additional tape copies, as well as transfer the videos to CDs or any
other format for non-broadcast use in marketing its business, without payment of
royalty or license fees to Heartbeat.
