Item 4.  Description of Securities.

         The Common Stock of the  Registrant is  registered  under Section 12 of
the Exchange Act.


Item 5.  Interests of Named Experts and Counsel.

         Not applicable.


Item 6.  Indemnification of Directors and Officers.

         Section  145 of the General  Corporation  Law of  Delaware,  as amended
("GCL"), authorizes a Delaware corporation to indemnify its officers, directors,
employees  and  agents  under  certain   circumstances   against   expenses  and
liabilities  incurred in legal  proceedings  involving  such persons  because of
their holding or having held such positions with the corporation and to purchase
and maintain insurance for such indemnification.  Article Tenth of the Company's
Certificate of Incorporation, as amended, provides in

                                      II-1

<PAGE>



substance that the Company shall  indemnify its officers,  directors,  employees
and agents to the  fullest  extent  permitted  by Section 145 of the GCL and the
Company has purchased insurance for such indemnification.

         Paragraph   7  of  Section   102(b)  of  the  GCL  permits  a  Delaware
corporation,  by so providing in its Certificate of Incorporation,  to eliminate
or  limit  the  personal  liability  of a  director  to the  corporation  or its
stockholders  for  damages  arising  out  of  certain  alleged  breaches  of the
director's duties to the corporation.  The GCL,  however,  provides that no such
limitation of liability may affect a director's liability with respect to any of
the  following:  (i)  any  breach  of the  director's  duty  of  loyalty  to the
corporation or its stockholders, (ii) for acts or omissions not in good faith or
which involve  intentional  misconduct or a knowing  violation of law, (iii) for
unlawful payment of dividends or unlawful  purchase or redemption of its capital
stock, or (iv) for any transaction  from which the director  derived an improper
personal benefit.  Article Ninth of the Company's  Certificate of Incorporation,
as amended, eliminates the personal liability of the directors of the Company to
the fullest extent permitted by Paragraph 7 of Section 102(b) of the GCL.


Item 7.  Exemption from Registration Claimed.

         Not applicable.

               (iii) Include any additional or changed  material  information on
          the plan of distribution;

Provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
Registration  Statement is on Form S-3 or Form S-8 and the information  required
in a  post-effective  amendment by those paragraphs is incorporated by reference
from periodic reports filed by the Registrant under the Exchange Act.

          (2)  That,  for  the  purpose  of  determining   liability  under  the
     Securities Act, each such post-effective  amendment shall be deemed to be a
     new registration  statement relating to the securities offered therein, and
     the  offering  of such  securities  at that time  shall be deemed to be the
     initial bona fide offering thereof.

          (3) To file a post-effective amendment to remove from registration any
     of the securities that remain unsold at the end of the offering.

     (b) The  undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Exchange Act (and where  applicable,  each filing of an employee  benefit plan's
annual  report   pursuant  to  Section  15(d)  of  the  Exchange  Act)  that  is
incorporated by reference in the Registration  Statement shall be deemed to be a
new registration  statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (c) Insofar as indemnification for liabilities arising under the Act may be
permitted to  directors,  officers  and  controlling  persons of the  Registrant
pursuant to the foregoing  provisions,  or  otherwise,  the Registrant  has been
advised that in the opinion of the Commission  such  indemnification  is against
public  policy  as  expressed  in  the   Securities   Act  and  is,   therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  Registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  Registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

                       NONQUALIFIED STOCK OPTION AGREEMENT

                  AGREEMENT  made as of the 25th day of September,  1996, by and
between  HUMASCAN  INC.,  a Delaware  corporation  (the  "Company"),  and Steven
Bussell (the "Former Director").

                  WHEREAS, the Former Director resigned from the Company's Board
of Directors  (the "Board") prior to June 20, 1996 at the request of the Company
and in order to facilitate the Company's  initial public offering of securities;
and

                  WHEREAS, in January 1996, the Former Director received, in his
capacity as a nonemployee  director of the Company and pursuant to the Company's
former  Nonemployee  Director Stock  Incentive  Plan,  options to purchase 1,500
shares of the Company's Common Stock, $.01 par value (the "Common Stock"); and

                  WHEREAS,   by  their   terms,   such  options  are  no  longer
exercisable  as a  consequence  of  the  termination  of the  Former  Director's
membership on the Board; and

                  WHEREAS,   on  September  25,  1996  (the  "Grant  Date"),  in
replacement of the options  previously  granted under the  Nonemployee  Director
Stock Incentive  Plan, the Board  authorized the grant to the Former Director of
an option  (the  "Option")  to  purchase  an  aggregate  of 1,500  shares of the
authorized but unissued  Common Stock,  conditioned  upon the Former  Director's
acceptance  thereof upon the terms and conditions  set forth in this  Agreement;
and

                  WHEREAS, the Former Director 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 Former
Director  the Option to purchase all or any part of an aggregate of 1,500 shares
of Common  Stock (the  "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
$6.00 per share, subject to adjustment as hereinafter provided.

                  4.  Exercisability.  The right to  purchase  25% of the Option
Shares  shall  become  exercisable  on  January  12 of each year for four  years
beginning  January 12, 1997. After a portion of the Option becomes  exercisable,
it shall remain exercisable except as otherwise provided herein, until the close
of business on September 25, 2006 (the "Exercise Period").


                                        1
                
<PAGE>



                  5.  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  Former   Director'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.

                  6.       Method of Exercise.

                           6.1      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.

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

                           6.3      Payment of Purchase Price.

                                     6.3.1  Cash Payment.  The  Former  Director
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.

                                     6.3.2 Cashless Payment. The Former Director
may, with the consent of the Board, use Common Stock of the Company owned by him
or her 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 Former Director 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.

                                     6.3.3   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.

                  7.  Nonassignability.  The Option shall not be  assignable  or
transferable  except by will or by the laws of descent and  distribution  in the
event of the death of the Former

                                        2

Director.  No  transfer  of the Option by the Former  Director 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.

                  8. Company Representations.  The Company hereby represents and
warrants to the Former Director that:

                           (i) the  Company,  by  appropriate  and all  required
         action,  is duly authorized to enter into this Agreement and consummate
         all of the transactions contemplated hereunder; and

                           (ii) the Option Shares,  when issued and delivered by
         the  Company to the Former  Director in  accordance  with the terms and
         conditions  hereof,  will be duly and validly issued and fully paid and
         non-assessable.

                  9. Former Director Representations. The Former Director hereby
represents and warrants to the Company that:

                           (i)      he or she is  acquiring the Option and shall
         acquire  the Option Shares for his  or her own  account and  not with a
         view towards the distribution thereof;

                           (ii) he or she has received a copy of all reports and
         documents  required  to be filed  by the  Company  with the  Commission
         pursuant to the  Exchange Act within the last 24 months and all reports
         issued by the Company to its stockholders;

                           (iii) he or she understands  that he or she must bear
         the economic risk of the investment in the Option Shares,  which cannot
         be sold by him or her unless they are  registered  under the Securities
         Act of  1933  (the  "Securities  Act")  or an  exemption  therefrom  is
         available  thereunder  and that the Company is under no  obligation  to
         register the Option Shares for sale under the Securities Act;

                           (iv) he or she has had  both the  opportunity  to ask
         questions  and receive  answers from the officers and  directors of the
         Company and all persons  acting on its behalf  concerning the terms and
         conditions  of the offer made  hereunder  and to obtain any  additional
         information  to the extent the Company  possesses  or may possess  such
         infor mation or can acquire it without  unreasonable  effort or expense
         necessary to verify the accuracy of the information  obtained  pursuant
         to clause (ii) above;

                           (v) he or she is aware that the  Company  shall place
         stop  transfer  orders with its transfer  agent against the transfer of

                           Re:      Purchase of Option Shares

Gentlemen:

                  In  accordance  with my  Stock  Option  Agreement  dated as of
September 25, 1996  ("Agreement")  with HumaScan Inc. (the "Company"),  I hereby
irrevocably  elect to  exercise  the right to purchase  _________  shares of the
Company's  common stock,  par value $.01 per share ("Common  Stock"),  which are
being purchased for investment and not for resale.

                  As payment  for my  shares,  enclosed  is (check and  complete
applicable box[es]):

a  [personal  check]  [certified  check]  [bank  check]  payable to the order of
"HumaScan Inc." in the sum of $_________;

confirmation of wire transfer in the amount of $_____________; and/or

certificate for ____ shares of the Company's Common Stock, free and clear of any
encumbrances, duly endorsed, having a fair market value of $_________.

                  I hereby  represent,  warrant to, and agree with,  the Company
that:

                           (i) I am acquiring  the Option and shall  acquire the
         Option  Shares  for my own  account  and not  with a view  towards  the
         distribution thereof;

                           (ii)  I have  received  a copy  of  all  reports  and
         documents  required  to be filed  by the  Company  with the  Commission
         pursuant  to the  Securities  Exchange  Act of 1934  within the last 24
         months and all reports issued by the Company to its stockholders;

                           (iii) I understand that I must bear the economic risk
         of the  investment  in the Option  Shares,  which  cannot be sold by me
         unless  they are  registered  under  the  Securities  Act of 1933  (the
         "Securities  Act") or an exemption  therefrom is available and that the
         Company is under no  obligation  to register the Option Shares for sale
         under the Securities Act;

                           (iv) I have had both the opportunity to ask questions
         and receive  answers from the officers and directors of the Company and
         all persons acting on its behalf concerning the terms and conditions of
         the offer made hereunder and to obtain any additional information

         to the extent the Company  possesses or may possess such information or
         can  acquire it without  unreasonable  effort or expense  necessary  to
         verify the accuracy of the information obtained pursuant to clause (ii)
         above;

                           (v) I am aware  that the  Company  shall  place  stop
         transfer  orders with its  transfer  agent  against the transfer of the
         Option Shares in the absence of  registration  under the Securities Act
         or an exemption therefrom as provided herein;

                           (vi)    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 1933. The shares may not
                           be  sold  or  transferred  in  the  absence  of  such
                           registration  or an  exemption  therefrom  under said
                           Act."

                       NONQUALIFIED STOCK OPTION AGREEMENT

                  AGREEMENT  made as of the 25th day of September,  1996, by and
between HUMASCAN INC., a Delaware  corporation  (the  "Company"),  and Burton L.
Eichler (the "Former Director").

                  WHEREAS, the Former Director resigned from the Company's Board
of Directors  (the "Board") prior to June 20, 1996 at the request of the Company
and in order to facilitate the Company's  initial public offering of securities;
and

                  WHEREAS, in January 1996, the Former Director received, in his
capacity as a nonemployee  director of the Company and pursuant to the Company's
former  Nonemployee  Director Stock  Incentive  Plan,  options to purchase 1,500
shares of the Company's Common Stock, $.01 par value (the "Common Stock"); and

                  WHEREAS,   by  their   terms,   such  options  are  no  longer
exercisable  as a  consequence  of  the  termination  of the  Former  Director's
membership on the Board; and

                  WHEREAS,   on  September  25,  1996  (the  "Grant  Date"),  in
replacement of the options  previously  granted under the  Nonemployee  Director
Stock Incentive  Plan, the Board  authorized the grant to the Former Director of
an option  (the  "Option")  to  purchase  an  aggregate  of 1,500  shares of the
authorized but unissued  Common Stock,  conditioned  upon the Former  Director's
acceptance  thereof upon the terms and conditions  set forth in this  Agreement;
and

                  WHEREAS, the Former Director 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 Former
Director  the Option to purchase all or any part of an aggregate of 1,500 shares
of Common  Stock (the  "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
$6.00 per share, subject to adjustment as hereinafter provided.

                  4.  Exercisability.  The right to  purchase  25% of the Option
Shares  shall  become  exercisable  on  January  12 of each year for four  years
beginning  January 12, 1997. After a portion of the Option becomes  exercisable,
it shall remain exercisable except as otherwise provided herein, until the close
of business on September 25, 2006 (the "Exercise Period").

<PAGE>



                  5.  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  Former   Director'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.

                  6.       Method of Exercise.

                           6.1      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.

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

                           6.3      Payment of Purchase Price.

                                    6.3.1   Cash  Payment.  The  Former Director
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.

                                    6.3.2  Cashless Payment. The Former Director
may, with the consent of the Board, use Common Stock of the Company owned by him
or her 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 Former Director 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.

                                    6.3.3   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.

                  7.  Nonassignability.  The Option shall not be  assignable  or
transferable  except by will or by the laws of descent and  distribution  in the
event of the death of the Former

                                        2

Director.  No  transfer  of the Option by the Former  Director 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.

                  8. Company Representations.  The Company hereby represents and
warrants to the Former Director that:

                           (i) the  Company,  by  appropriate  and all  required
         action,  is duly authorized to enter into this Agreement and consummate
         all of the transactions contemplated hereunder; and

                           (ii) the Option Shares,  when issued and delivered by
         the  Company to the Former  Director in  accordance  with the terms and
         conditions  hereof,  will be duly and validly issued and fully paid and
         non-assessable.

                  9. Former Director Representations. The Former Director hereby
represents and warrants to the Company that:

                           (i)      he or she is acquiring  the Option and shall
         acquire the Option  Shares for  his or her own account and  not with  a
         view towards the distribution thereof;

                           (ii) he or she has received a copy of all reports and
         documents  required  to be filed  by the  Company  with the  Commission
         pursuant to the  Exchange Act within the last 24 months and all reports
         issued by the Company to its stockholders;

                           (iii) he or she understands  that he or she must bear

         available  thereunder  and that the Company is under no  obligation  to
         register the Option Shares for sale under the Securities Act;

                           (iv) he or she has had  both the  opportunity  to ask
         questions  and receive  answers from the officers and  directors of the
         Company and all persons  acting on its behalf  concerning the terms and
         conditions  of the offer made  hereunder  and to obtain any  additional
         information  to the extent the Company  possesses  or may possess  such
         infor mation or can acquire it without  unreasonable  effort or expense
         necessary to verify the accuracy of the information  obtained  pursuant
         to clause (ii) above;

                           (v) he or she is aware that the  Company  shall place
         stop  transfer  orders with its transfer  agent against the transfer of
         the Option Shares in the absence of  registration  under the Securities
         Act or an exemption therefrom as provided herein; and

                           (vi) 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 1933. The shares may not

                           registration  or an  exemption  therefrom  under said
                           Act."

                           "The shares represented by this certificate have been
                           acquired pursuant to a Stock Option Agreement,  dated
                           as of September  25, 1996, a copy of which is on file

                           or  disposed of except in  accordance  with the terms
                           and conditions thereof."

                  10. Restriction on Transfer of Option Shares. Anything in this
Agreement to the contrary  notwithstanding,  the Former  Director  hereby agrees
that he or she shall not sell, transfer by any means or otherwise dispose of the
Option Shares acquired by him or her without  registration  under the Securities

(ii) the Former  Director has furnished the Company with notice of such proposed

Attention:  Board of Directors

                           Re:      Purchase of Option Shares

Gentlemen:

                  In  accordance  with my  Stock  Option  Agreement  dated as of
September 25, 1996  ("Agreement")  with HumaScan Inc. (the "Company"),  I hereby
irrevocably  elect to  exercise  the right to purchase  _________  shares of the
Company's  common stock,  par value $.01 per share ("Common  Stock"),  which are
being purchased for investment and not for resale.

                  As payment  for my  shares,  enclosed  is (check and  complete
applicable box[es]):

a  [personal  check]  [certified  check]  [bank  check]  payable to the order of
"HumaScan Inc." in the sum of $_________;

confirmation of wire transfer in the amount of $_____________; and/or

certificate for ____ shares of the Company's Common Stock, free and clear of any
encumbrances, duly endorsed, having a fair market value of $_________.

                  I hereby  represent,  warrant to, and agree with,  the Company
that:

                           (i) I am acquiring  the Option and shall  acquire the
         Option  Shares  for my own  account  and not  with a view  towards  the
         distribution thereof;

                           (ii)  I have  received  a copy  of  all  reports  and
         documents  required  to be filed  by the  Company  with the  Commission
         pursuant  to the  Securities  Exchange  Act of 1934  within the last 24
         months and all reports issued by the Company to its stockholders;

                           (iii) I understand that I must bear the economic risk
         of the  investment  in the Option  Shares,  which  cannot be sold by me
         unless  they are  registered  under  the  Securities  Act of 1933  (the
         "Securities  Act") or an exemption  therefrom is available and that the
         Company is under no  obligation  to register the Option Shares for sale
         under the Securities Act;

                           (iv) I have had both the opportunity to ask questions
         and receive  answers from the officers and directors of the Company and
         all persons acting on its behalf concerning the terms and conditions of
         the offer made hereunder and to obtain any additional information

         to the extent the Company  possesses or may possess such information or
         can  acquire it without  unreasonable  effort or expense  necessary  to
         verify the accuracy of the information obtained pursuant to clause (ii)
         above;

                           (v) I am aware  that the  Company  shall  place  stop
         transfer  orders with its  transfer  agent  against the transfer of the
         Option Shares in the absence of  registration  under the Securities Act
         or an exemption therefrom as provided herein;

                           (vi)    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 1933. The shares may not
                           be  sold  or  transferred  in  the  absence  of  such
                           registration  or an  exemption  therefrom  under said
                           Act."

                           "The shares represented by this certificate have been
                           acquired pursuant to a Stock Option Agreement,  dated
                           as of September  25, 1996, a copy of which is on file
                           with the Company, and may not be transferred, pledged
                           or  disposed of except in  accordance  with the terms
                           and conditions thereof."

Kindly forward to me my certificate at your earliest convenience.

Very truly yours,

                       NONQUALIFIED STOCK OPTION AGREEMENT

                  AGREEMENT  made as of the 25th day of September,  1996, by and
between HUMASCAN INC., a Delaware  corporation (the "Company"),  and Robert Lane
(the "Former Director").

                  WHEREAS, the Former Director resigned from the Company's Board
of Directors  (the "Board") prior to June 20, 1996 at the request of the Company
and in order to facilitate the Company's  initial public offering of securities;
and

                  WHEREAS, in January 1996, the Former Director received, in his
capacity as a nonemployee  director of the Company and pursuant to the Company's
former  Nonemployee  Director Stock  Incentive  Plan,  options to purchase 1,500
shares of the Company's Common Stock, $.01 par value (the "Common Stock"); and

                  WHEREAS,   by  their   terms,   such  options  are  no  longer
exercisable  as a  consequence  of  the  termination  of the  Former  Director's
membership on the Board; and

                  WHEREAS,   on  September  25,  1996  (the  "Grant  Date"),  in
replacement of the options  previously  granted under the  Nonemployee  Director
Stock Incentive  Plan, the Board  authorized the grant to the Former Director of
an option  (the  "Option")  to  purchase  an  aggregate  of 1,500  shares of the
authorized but unissued  Common Stock,  conditioned  upon the Former  Director's
acceptance  thereof upon the terms and conditions  set forth in this  Agreement;
and

                  WHEREAS, the Former Director 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 Former
Director  the Option to purchase all or any part of an aggregate of 1,500 shares
of Common  Stock (the  "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
$6.00 per share, subject to adjustment as hereinafter provided.

                  4.  Exercisability.  The right to  purchase  25% of the Option
Shares  shall  become  exercisable  on  January  12 of each year for four  years
beginning  January 12, 1997. After a portion of the Option becomes  exercisable,
it shall remain exercisable except as otherwise provided herein, until the close
of business on September 25, 2006 (the "Exercise Period").


                                        1
                   
<PAGE>



                  5.  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  Former   Director'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.

                  6.       Method of Exercise.

                           6.1      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.

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

                           6.3      Payment of Purchase Price.

                                    6.3.1   Cash Payment.  The Former Director
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.

                                    6.3.2   Cashless Payment.  The Former 
Director  may,  with the consent of the Board,  use Common  Stock of the Company
owned by him or her 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 Former  Director 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.

                                    6.3.3   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.

                  7.  Nonassignability.  The Option shall not be  assignable  or
transferable  except by will or by the laws of descent and  distribution  in the
event of the death of the Former

                                        2

Director.  No  transfer  of the Option by the Former  Director 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.

                  8. Company Representations.  The Company hereby represents and
warrants to the Former Director that:

                           (i) the  Company,  by  appropriate  and all  required
         action,  is duly authorized to enter into this Agreement and consummate
         all of the transactions contemplated hereunder; and

                           (ii) the Option Shares,  when issued and delivered by
         the  Company to the Former  Director in  accordance  with the terms and
         conditions  hereof,  will be duly and validly issued and fully paid and
         non-assessable.

                  9. Former Director Representations. The Former Director hereby
represents and warrants to the Company that:

                           (i)      he or she is acquiring the Option and  shall
         acquire  the Option Shares  for his or her  own account and  not with a
         view towards the distribution thereof;

                           (ii) he or she has received a copy of all reports and
         documents  required  to be filed  by the  Company  with the  Commission

                           (iii) he or she understands  that he or she must bear

         available  thereunder  and that the Company is under no  obligation  to
         register the Option Shares for sale under the Securities Act;

                           (iv) he or she has had  both the  opportunity  to ask
         questions  and receive  answers from the officers and  directors of the

         information  to the extent the Company  possesses  or may possess  such
         infor mation or can acquire it without  unreasonable  effort or expense
         necessary to verify the accuracy of the information  obtained  pursuant
         to clause (ii) above;

                           (v) he or she is aware that the  Company  shall place

                           registration  or an  exemption  therefrom  under said
                           Act."

                           "The shares represented by this certificate have been
                           acquired pursuant to a Stock Option Agreement,  dated
                           as of September  25, 1996, a copy of which is on file

Gentlemen:

                  In  accordance  with my  Stock  Option  Agreement  dated as of
September 25, 1996  ("Agreement")  with HumaScan Inc. (the "Company"),  I hereby
irrevocably  elect to  exercise  the right to purchase  _________  shares of the
Company's  common stock,  par value $.01 per share ("Common  Stock"),  which are
being purchased for investment and not for resale.

                  As payment  for my  shares,  enclosed  is (check and  complete
applicable box[es]):

a  [personal  check]  [certified  check]  [bank  check]  payable to the order of
"HumaScan Inc." in the sum of $_________;

confirmation of wire transfer in the amount of $_____________; and/or

certificate for ____ shares of the Company's Common Stock, free and clear of any
encumbrances, duly endorsed, having a fair market value of $_________.

                  I hereby  represent,  warrant to, and agree with,  the Company
that:

                           (i) I am acquiring  the Option and shall  acquire the
         Option  Shares  for my own  account  and not  with a view  towards  the
         distribution thereof;

                           (ii)  I have  received  a copy  of  all  reports  and
         documents  required  to be filed  by the  Company  with the  Commission
         pursuant  to the  Securities  Exchange  Act of 1934  within the last 24
         months and all reports issued by the Company to its stockholders;

                           (iii) I understand that I must bear the economic risk
         of the  investment  in the Option  Shares,  which  cannot be sold by me
         unless  they are  registered  under  the  Securities  Act of 1933  (the
         "Securities  Act") or an exemption  therefrom is available and that the
         Company is under no  obligation  to register the Option Shares for sale
         under the Securities Act;

                           (iv) I have had both the opportunity to ask questions
         and receive  answers from the officers and directors of the Company and
         all persons acting on its behalf concerning the terms and conditions of
         the offer made hereunder and to obtain any additional information

         to the extent the Company  possesses or may possess such information or
         can  acquire it without  unreasonable  effort or expense  necessary  to
         verify the accuracy of the information obtained pursuant to clause (ii)
         above;

                           (v) I am aware  that the  Company  shall  place  stop
         transfer  orders with its  transfer  agent  against the transfer of the
         Option Shares in the absence of  registration  under the Securities Act
         or an exemption therefrom as provided herein;

                           (vi)    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 1933. The shares may not
                           be  sold  or  transferred  in  the  absence  of  such
                           registration  or an  exemption  therefrom  under said
                           Act."

                           "The shares represented by this certificate have been
                           acquired pursuant to a Stock Option Agreement,  dated
                           as of September  25, 1996, a copy of which is on file
                           with the Company, and may not be transferred, pledged
                           or  disposed of except in  accordance  with the terms
                           and conditions thereof."

Kindly forward to me my certificate at your earliest convenience.

Very truly yours,

                       NONQUALIFIED STOCK OPTION AGREEMENT

                  AGREEMENT made as of the 25th day of September, 1996, by and 
between HUMASCAN INC., a Delaware  corporation (the "Company"),  and Zsigmond L.
Sagi, Ph.D. (the "Former Director").

                  WHEREAS, the Former Director resigned from the Company's Board
of Directors  (the "Board") prior to June 20, 1996 at the request of the Company
and in order to facilitate the Company's  initial public offering of securities;
and

                  WHEREAS, in January 1996, the Former Director received, in his
capacity as a nonemployee  director of the Company and pursuant to the Company's
former  Nonemployee  Director Stock  Incentive  Plan,  options to purchase 1,500
shares of the Company's Common Stock, $.01 par value (the "Common Stock"); and

                  WHEREAS,   by  their   terms,   such  options  are  no  longer
exercisable  as a  consequence  of  the  termination  of the  Former  Director's
membership on the Board; and

                  WHEREAS,   on  September  25,  1996  (the  "Grant  Date"),  in
replacement of the options  previously  granted under the  Nonemployee  Director
Stock Incentive  Plan, the Board  authorized the grant to the Former Director of
an option  (the  "Option")  to  purchase  an  aggregate  of 1,500  shares of the
authorized but unissued  Common Stock,  conditioned  upon the Former  Director's
acceptance  thereof upon the terms and conditions  set forth in this  Agreement;
and

                  WHEREAS, the Former Director 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 Former
Director  the Option to purchase all or any part of an aggregate of 1,500 shares
of Common  Stock (the  "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
$6.00 per share, subject to adjustment as hereinafter provided.

                  4.  Exercisability.  The right to  purchase  25% of the Option
Shares  shall  become  exercisable  on  January  12 of each year for four  years
beginning  January 12, 1997. After a portion of the Option becomes  exercisable,
it shall remain exercisable except as otherwise provided herein, until the close
of business on September 25, 2006 (the "Exercise Period").

<PAGE>



                  5.  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  Former   Director'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.

                  6.       Method of Exercise.

                           6.1      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.

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

                           6.3      Payment of Purchase Price.

                                    6.3.1   Cash Payment.  The Former Director
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.

                                    6.3.2   Cashless Payment.  The Former 
Director  may,  with the consent of the Board,  use Common  Stock of the Company
owned by him or her 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 Former  Director 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.

                                    6.3.3   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.

                  7.  Nonassignability.  The Option shall not be  assignable  or
transferable  except by will or by the laws of descent and  distribution  in the
event of the death of the Former

                                        2

Director.  No  transfer  of the Option by the Former  Director 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.

                  8. Company Representations.  The Company hereby represents and
warrants to the Former Director that:

                           (i) the  Company,  by  appropriate  and all  required
         action,  is duly authorized to enter into this Agreement and consummate
         all of the transactions contemplated hereunder; and

                           (ii) the Option Shares,  when issued and delivered by
         the  Company to the Former  Director in  accordance  with the terms and
         conditions  hereof,  will be duly and validly issued and fully paid and
         non-assessable.

                  9. Former Director Representations. The Former Director hereby
represents and warrants to the Company that:

                           (i)      he or she is acquiring the Option and shall
         acquire  the Option  Shares for his  or her own account and  not with a
         view towards the distribution thereof;

                           (ii) he or she has received a copy of all reports and
         documents  required  to be filed  by the  Company  with the  Commission

         issued by the Company to its stockholders;

                           (iii) he or she understands  that he or she must bear

         available  thereunder  and that the Company is under no  obligation  to
         register the Option Shares for sale under the Securities Act;

                           (iv) he or she has had  both the  opportunity  to ask

         information  to the extent the Company  possesses  or may possess  such
         infor mation or can acquire it without  unreasonable  effort or expense
         necessary to verify the accuracy of the information  obtained  pursuant
         to clause (ii) above;

                           (v) he or she is aware that the  Company  shall place
         stop  transfer  orders with its transfer  agent against the transfer of
         the Option Shares in the absence of  registration  under the Securities
         Act or an exemption therefrom as provided herein; and

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

                           registration  or an  exemption  therefrom  under said
                           Act."

                           "The shares represented by this certificate have been
                           acquired pursuant to a Stock Option Agreement,  dated
                           as of September  25, 1996, a copy of which is on file

                           (i) I am acquiring  the Option and shall  acquire the
         Option  Shares  for my own  account  and not  with a view  towards  the
         distribution thereof;

                           (ii)  I have  received  a copy  of  all  reports  and
         documents  required  to be filed  by the  Company  with the  Commission
         pursuant  to the  Securities  Exchange  Act of 1934  within the last 24
         months and all reports issued by the Company to its stockholders;

                           (iii) I understand that I must bear the economic risk
         of the  investment  in the Option  Shares,  which  cannot be sold by me
         unless  they are  registered  under  the  Securities  Act of 1933  (the
         "Securities  Act") or an exemption  therefrom is available and that the
         Company is under no  obligation  to register the Option Shares for sale
         under the Securities Act;

                           (iv) I have had both the opportunity to ask questions
         and receive  answers from the officers and directors of the Company and
         all persons acting on its behalf concerning the terms and conditions of
         the offer made hereunder and to obtain any additional information

         to the extent the Company  possesses or may possess such information or
         can  acquire it without  unreasonable  effort or expense  necessary  to
         verify the accuracy of the information obtained pursuant to clause (ii)
         above;

                           (v) I am aware  that the  Company  shall  place  stop
         transfer  orders with its  transfer  agent  against the transfer of the
         Option Shares in the absence of  registration  under the Securities Act
         or an exemption therefrom as provided herein;

                           (vi)    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 1933. The shares may not
                           be  sold  or  transferred  in  the  absence  of  such
                           registration  or an  exemption  therefrom  under said
                           Act."

                           "The shares represented by this certificate have been

                           as of September  25, 1996, a copy of which is on file
                           with the Company, and may not be transferred, pledged

                           and conditions thereof."

Kindly forward to me my certificate at your earliest convenience.

Very truly yours,

                       NONQUALIFIED STOCK OPTION AGREEMENT

                  AGREEMENT  made as of the 25th day of September,  1996, by and
between HUMASCAN INC., a Delaware corporation (the "Company"), and Leonard Brown
(the "Former Director").

                  WHEREAS, the Former Director resigned from the Company's Board
of Directors  (the "Board") prior to June 20, 1996 at the request of the Company
and in order to facilitate the Company's  initial public offering of securities;
and

                  WHEREAS, in January 1996, the Former Director received, in his
capacity as a nonemployee  director of the Company and pursuant to the Company's
former  Nonemployee  Director Stock  Incentive  Plan,  options to purchase 1,500
shares of the Company's Common Stock, $.01 par value (the "Common Stock"); and

                  WHEREAS,   by  their   terms,   such  options  are  no  longer
exercisable  as a  consequence  of  the  termination  of the  Former  Director's
membership on the Board; and

                  WHEREAS,   on  September  25,  1996  (the  "Grant  Date"),  in
replacement of the options  previously  granted under the  Nonemployee  Director
Stock Incentive  Plan, the Board  authorized the grant to the Former Director of
an option  (the  "Option")  to  purchase  an  aggregate  of 1,500  shares of the
authorized but unissued  Common Stock,  conditioned  upon the Former  Director's
acceptance  thereof upon the terms and conditions  set forth in this  Agreement;
and

                  WHEREAS, the Former Director 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 Former
Director  the Option to purchase all or any part of an aggregate of 1,500 shares
of Common  Stock (the  "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
$6.00 per share, subject to adjustment as hereinafter provided.

                  4.  Exercisability.  The right to  purchase  25% of the Option
Shares  shall  become  exercisable  on  January  12 of each year for four  years
beginning  January 12, 1997. After a portion of the Option becomes  exercisable,
it shall remain exercisable except as otherwise provided herein, until the close
of business on September 25, 2006 (the "Exercise Period").

                  5.  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  Former   Director'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.

                  6.       Method of Exercise.

                           6.1      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.

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

                           6.3      Payment of Purchase Price.

                                    6.3.1   Cash Payment.  The Former Director
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.

                                    6.3.2   Cashless Payment.  The Former 
Director  may,  with the consent of the Board,  use Common  Stock of the Company
owned by him or her 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 Former  Director 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.

                                    6.3.3   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.

                  7.  Nonassignability.  The Option shall not be  assignable  or
transferable  except by will or by the laws of descent and  distribution  in the
event of the death of the Former

                                        2

Director.  No  transfer  of the Option by the Former  Director 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.

                  8. Company Representations.  The Company hereby represents and
warrants to the Former Director that:

                           (i) the  Company,  by  appropriate  and all  required
         action,  is duly authorized to enter into this Agreement and consummate
         all of the transactions contemplated hereunder; and

                           (ii) the Option Shares,  when issued and delivered by
         the  Company to the Former  Director in  accordance  with the terms and
         conditions  hereof,  will be duly and validly issued and fully paid and
         non-assessable.

                  9. Former Director Representations. The Former Director hereby
represents and warrants to the Company that:

                           (i)      he or she is acquiring the Option and  shall
         acquire  the Option  Shares for his or her own  account and not  with a
         view towards the distribution thereof;

                           (ii) he or she has received a copy of all reports and
         documents  required  to be filed  by the  Company  with the  Commission

         issued by the Company to its stockholders;

                           (iii) he or she understands  that he or she must bear

         available  thereunder  and that the Company is under no  obligation  to
         register the Option Shares for sale under the Securities Act;

         infor mation or can acquire it without  unreasonable  effort or expense

         to clause (ii) above;

                           (v) he or she is aware that the  Company  shall place
         stop  transfer  orders with its transfer  agent against the transfer of
         the Option Shares in the absence of  registration  under the Securities
         Act or an exemption therefrom as provided herein; and

                           (vi) The  certificates  evidencing  the Option Shares

that:

                           (i) I am acquiring  the Option and shall  acquire the

                                                              November 20, 1997




HumaScan Inc.

Cranford, New Jersey 07016

Dear Sirs:

                  Reference  is made to the  Registration  Statement on Form S-8
("Registration  Statement")  filed by  HumaScan  Inc.  ("Company"),  a  Delaware
corporation,  under the Securities Act of 1933, as amended ("Act"), with respect
to an  aggregate  of 850,000  shares of common  stock,  par value $.01 per share
("Common  Stock"),  to be offered by the Company under the Company's  1996 Stock
Incentive Plan and certain other employee  benefit plans under separate  written
agreements ("Plans").

                  We have examined  such  documents  and  considered  such legal
matters as we have deemed  necessary  and  relevant as the basis for the opinion
set  forth  below.  With  respect  to  such  examination,  we have  assumed  the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all documents submitted to
us as reproduced or certified  copies,  and the authenticity of the originals of
those latter  documents.  As to questions of fact material to this  opinion,  we
have, to the extent deemed appropriate,  relied upon certain  representations of
certain  officers and  employees  of the  Company.  We have also assumed that in
granting  future  awards  under  the 1996  Stock  Incentive  Plan,  the Board of
Directors of the Company or the appropriate  committee  thereunder will exercise
its discretion in  establishing  the terms of such awards within the permissible
limits of the law of the State of Delaware.

                  Based upon the  foregoing,  it is our opinion  that the Common
Stock to be issued by the Company under the Plans,  when sold in accordance with
the terms of the Plans and the individual  instruments governing their issuance,
will be legally  issued,  fully  paid and  nonassessable,  although  they may be
subject to  contractual  restrictions  established  by the  applicable  Plans or
instruments.

                  In giving this opinion,  we have assumed that all certificates
for the Company's shares of Common Stock, prior to their issuance,  will be duly
executed on behalf of the Company by the Company's transfer agent and registered
by the  Company's  registrar,  if  necessary,  and will  conform,  except  as to
denominations, to specimens which we have examined.

                  We hereby  consent to the use of this opinion as an exhibit to
the  Registration  Statement,  to the use of our name as your counsel and to all
references  made  to us in the  Registration  Statement  and  in the  Prospectus
forming a part thereof.  In giving this consent,  we do not hereby admit that we
are in the category of persons whose consent is required  under Section 7 of the
Act, or the rules and regulations promulgated thereunder.

                                                   Very truly yours,

                                                   /s/ Graubard Mollen & Miller
