NONQUALIFIED STOCK OPTION AGREEMENT


     AGREEMENT made as of the 12th day of August, 1998, by and between HUMASCAN
INC., a Delaware corporation ("Company"), and PHYSICIANS WORLD COMMUNICATIONS
GROUP ("Consultant").

     WHEREAS, the Consultant and the Company have entered into a Consulting
Agreement, dated as of July 1, 1998 ("Consulting Agreement"), pursuant to which
the Consultant shall provide certain consulting services to the Company;

     WHEREAS, by written consent dated August 12, 1998 ("Grant Date"), the Board
of Directors of the Company ("Board") authorized the grant to the Consultant of
an option ("Option") to purchase an aggregate of 50,000 shares of the authorized
but unissued Common Stock of the Company, $.01 par value ("Common Stock"),
conditioned upon the Consultant's acceptance thereof upon the terms and
conditions set forth in this Agreement; and

     WHEREAS, the Consultant desires to acquire the Option on the terms and
conditions set forth in this Agreement;

     IT IS AGREED:

1.   Grant of Stock Option. The Company hereby grants the Consultant the Option
to purchase all or any part of an aggregate of 50,000 shares of Common Stock
("Option Shares") on the terms and conditions set forth herein.

2.   Nonqualified Stock Option. The Option represented hereby is not intended to
be an Option which qualifies as an "Incentive Stock Option" under Section 422 of
the Internal Revenue Code of 1986, as amended.

3.   Exercise Price. The exercise price of the Option shall be $1.375 per share,
subject to adjustment as hereinafter provided.

4.   Exercisability. The Option is exercisable as follows: (i) the right to
purchase 25,000 of the Option Shares shall become exercisable on the Grant Date;
and (ii) the right to purchase 25,000 of the Option Shares shall become
exercisable on December 31, 1998. After a portion of the Option becomes
exercisable, it shall remain exercisable, except as otherwise provided herein,
until the date that is 5 years after the Grant Date.

5.   Effect of Termination of Service.

     5.1 Termination by Consultant. If the Consultant's service as a consultant
to the Company is terminated by the Consultant for any reason, the portion of
the Option, if any, that was exercisable as of the date of termination of
service may thereafter be exercised by the Consultant until the expiration of
the Exercise Period. The portion of the Option, if any, that was not exercisable
as of the date of the termination of service shall immediately terminate upon
the termination of service.

     5.2 Termination by the Company. If the Consultant's service as a consultant
to the Company is terminated by the Company for proper cause pursuant to Section
3.2 of the Consulting Agreement, the Option, whether or not then exercisable,
shall immediately expire upon such termination.

6.   Adjustments. In the event of any merger, reorganization, consolidation,
recapitalization, dividend (other than cash dividend), stock split, reverse
stock split, or other change in corporate structure affecting the number of
issued shares of Common Stock, the Company shall adjust the number and kind of
Option Shares and the exercise price of the Option proportionally in order to
prevent the dilution or enlargement of the Consultant's proportionate interest
in the Company and his rights hereunder, provided that the number of Option
Shares shall always be a whole number and any fractional shares resulting from
such adjustments shall be eliminated.

7.   Method of Exercise.

     7.1 Notice to the Company. The Option shall be exercised in whole or in
part by written notice in substantially the form attached hereto as Exhibit A
directed to the Company at its principal place of business accompanied by full
payment as hereinafter provided of the exercise price for the number of Option
Shares specified in the notice.

     7.2 Delivery of Option Shares. The Company shall deliver a certificate for
the Option Shares to the Consultant as soon as practicable after payment
therefor.

     7.3 Payment of Purchase Price.

         7.3.1 Cash Payment. The Consultant shall make cash payments by wire
transfer, certified or bank check or personal check, in each case payable to the
order of the Company; the Company shall not be required to deliver certificates
for Option Shares until the Company has confirmed the receipt of good and
available funds in payment of the purchase price thereof.

         7.3.2 Cashless Payment. The Consultant may, with the consent of the
Board, use Common Stock of the Company owned by it to pay the purchase price for
the Option Shares by delivery of stock certificates in negotiable form which are
effective to transfer good and valid title thereto to the Company, free of any
liens or encumbrances. Shares of Common Stock used for this purpose shall be
valued at the fair market value, as determined by the Board in its sole
discretion. Alternatively, at the election of the Consultant and with the
consent of the Board, the Company may retain from the Option Shares that number
of shares having a fair market value on the date of exercise (as determined by
the Board in its sole discretion) equal to the option price of the number of
Option Shares for which the Option is being exercised.

         7.3.3 Exchange Act Compliance. Notwithstanding the foregoing, the
Company shall have the right to reject payment in the form of Common Stock if in
the opinion of counsel for the Company, (i) it could result in an event of
"recapture" under Section 16(b) of the Securities Exchange Act of 1934
("Exchange Act"); (ii) such shares of Common Stock may not be sold or
transferred to the Company; or (iii) such transfer could create legal
difficulties for the Company.

8.   Nonassignability. The Option shall not be assignable or transferable except
to the principals of the Consultant and by will or by the laws of descent and
distribution in the event of the death of a holder that is a principal of the
Consultant. No transfer of the Option by a principal of the Consultant by will
or by the laws of descent and distribution shall be effective to bind the
Company unless the Company shall have been furnished with written notice thereof
and a copy of the will and such other evidence as the Company may deem necessary
to establish the validity of the transfer and the acceptance by the transferee
or transferees of the terms and conditions of the Option.

registration under the Securities Act or an exemption therefrom as provided
herein; and

     (6) The certificates evidencing the Option Shares shall bear the following
legends:

         "The shares represented by this certificate have been acquired for
         investment and have not been registered under the Securities Act of
