is  the  registered  Holder (the "Holder") of  one  million,  two

Purchase  Warrants  (the "Warrants") to purchase  shares  of  the

are   being  issued  in  connection  with  a  certain  consulting

     This  Warrant Certificate is subject to the following  terms
and conditions:

     1.   EXERCISE OF WARRANT.

          (A)   Each Warrant enables the Holder, subject  to  the
provisions  of  this  Warrant Certificate to  purchase  from  the
Company at any time and from time to time commencing on the  date
hereof  (the "Initial Exercise Date") through and including  5:00
p.m., New York local time on MAY 19, 2010 (the "Expiration Date")
one  (1)  fully  paid and non-assessable share  of  Common  Stock
("Shares")  upon due presentation and surrender of  this  Warrant
Certificate accompanied by payment of the purchase price of $0.01

provisions  set forth in subsection (B) hereof.  Payment  of  the
Exercise Price shall be made in lawful money of the United States
of  America  by  certified check payable to the  Company  at  its
principal   office  at  2275  Swallow  Hill  Road,  Bldg.   2500;
Pittsburgh,  PA  15220.   As hereinafter provided,  the  Exercise
Price  and number of Shares purchasable upon the exercise of  the
Warrants  are  subject  to modification or  adjustment  upon  the
happening of certain events.

          (B)   This  Warrant Certificate is exercisable  by  the
Holder in person or by attorney duly authorized in writing at the
principal office of the Company in the following amounts:

               1) 100,000 Warrants are exercisable at any time on
               or  after the Initial Exercise Date and until  the
               Expiration Date;

               2)  150,000 Warrants are exercisable at such  time
               as  phase 1 of the development of the non-invasive
               glucose   sensor  is  completed  and   until   the
               Expiration Date, provided the Holder is  providing
               services  to  the  Company  under  the  Consulting
               Agreement.

               3)  250,000 Warrants are exercisable at such  time
               as  phase 2 of the development of the non-invasive
               glucose   sensor  is  completed  and   until   the
               Expiration Date, provided the Holder is  providing
               services  to  the  Company  under  the  Consulting
               Agreement.

               4)   727,000 Warrants are exercisable at such time
               as a working prototype of the non-invasive glucose
               sensor is complete and functional.

     2.   EXCHANGE, FRACTIONAL SHARES, TRANSFER.

          (A)   Upon  surrender  to  the  Company,  this  Warrant
Certificate  may be exchanged for another Warrant Certificate  or
Warrant  Certificates  evidencing  a  like  aggregate  number  of
Warrants.   If  this Warrant Certificate shall  be  exercised  in
part,  the  Holder  shall be entitled to receive  upon  surrender
hereof   another  Warrant  Certificate  or  Warrant  Certificates
evidencing the number of Warrants not exercised;

          (B)   Anything  herein to the contrary notwithstanding,
in  no  event  shall the Company be obligated  to  issue  Warrant
Certificates evidencing other than a whole number of Warrants  or
issue certificates evidencing other than a whole number of Shares
upon the exercise of this Warrant Certificate; provided, however,
that the Company shall pay with respect to any such fraction of a
Share  an amount of cash based upon the current Market Price  (or
book  value,  if  there  shall be no  Market  Price)  for  Shares
purchasable  upon  exercise hereof, as determined  in  accordance
with  the  following sentence.  Market Price for the  purpose  of
this  Section  2(B) shall mean (i) the closing  sale  price,  for
sixty  (60)  consecutive business days of  the  Common  Stock  as
reported by the National Association of Securities Dealers,  Inc.
Automated Quotation System or (ii) the last reported sale  price,
for  sixty (60) consecutive business days on the primary exchange
on  which  the  Common Stock is traded, if the  Common  Stock  is
traded on a national securities exchange;

          (C)  the Company may deem and treat the person in whose
name  this Warrant Certificate is registered as the absolute true
and lawful owner hereof for all purposes whatsoever; and

          (D)   This  Warrant  Certificate  is  not  transferable
except in accordance with Section 9 hereof.

     3.    RIGHTS OF A HOLDER.  No Holder shall be deemed  to  be
the Holder of Common Stock or any other securities of the Company
that  may at any time be issuable on the exercise hereof for  any
purpose  nor  shall  anything contained herein  be  construed  to
confer upon the Holder 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 reorganization, issuance of stock, reclassification  or
conversion of stock, change of par value, consolidation,  merger,
conveyance, or otherwise) or to receive notice of meetings or  to
receive  dividends  or subscription rights or otherwise  until  a
Warrant   shall  have  been  exercised  and  the   Common   Stock
purchasable upon the exercise thereof shall have become issuable.

     4.   REGISTRATION.  The Company shall maintain books for the
registration  of Warrants.  The Company shall issue and  register
the Warrants in the name(s) of the Holder(s).  The Warrants shall
be  signed  manually  by the Chairman, Chief  Executive  Officer,
President  or  any  Vice President on the one hand,  and  another
officer  of  the  Company on the other  hand.   Warrants  may  be
exchanged  at the option of the Holder, when surrendered  at  the
office of the Company, for another Warrant, or other Warrants  of
different  denominations, of like tenor and representing  in  the
aggregate the right to purchase a like number of Shares.  Subject
to the terms of this Warrant Certificate, upon such surrender and
payment  of  the  Exercise Price at any time  after  the  Initial
Exercise  Date,  the  Company shall issue and  deliver  with  all
reasonable dispatch to or upon the written order of the Holder of
such  Warrants  and  in such name or names  as  such  Holder  may
designate, a certificate or certificates for the number  of  full
Shares  so  purchased upon the exercise of such  Warrants.   Such
certificate  or certificates shall be deemed to have been  issued
and  any person so designated to be named therein shall be deemed
to have become the Holder of record of such Shares as of the date
of  the  surrender of such Warrants and payment of  the  Exercise
Price;  provided, however, that if, at the date of surrender  and
payment, the transfer books of the Common Stock shall be  closed,
the  certificates for the Shares shall be issuable as of the date
on  which  such  books shall be opened and until  such  date  the
Company  shall  be under no duty to deliver any  certificate  for
such  Shares;  provided,  further, however,  that  such  transfer
books, unless otherwise required by law or by applicable rule  of
any  national securities exchange, shall not be closed at any one
time for a period longer than 20 days.

     5.    STAMP TAX.  The Company will pay any documentary stamp
taxes attributable to the initial issuance of the Shares issuable
upon  the  exercise of the Warrants; provided, however, that  the
Company  shall not be required to pay any tax or taxes which  may
be payable in respect of any transfer involved in the issuance or
delivery of any certificates for Shares in a name other than that
of  the Holder in respect of which such Shares are issued, and in
such  case the Company shall not be required to issue or  deliver
any  certificate  for  Shares or any  Warrant  until  the  person
requesting  the same has paid to the Company the amount  of  such
tax  or  has established to the Company's satisfaction that  such
tax has been paid.

     6.    LOST, STOLEN OR MUTILATED CERTIFICATES.  In case  this
Warrant   Certificate  shall  be  mutilated,  lost,   stolen   or
destroyed, the Company may, in its discretion, issue and  deliver
in  exchange  and substitution for and upon cancellation  of  the
mutilated Warrant Certificate, or in lieu of and substitution for
the  lost, stolen or destroyed Warrant Certificate, a new Warrant
Certificate  of  like tenor representing an equivalent  right  or
interest, but only upon receipt of evidence satisfactory  to  the
Company  of such loss, theft or destruction and an indemnity,  if
requested, also satisfactory to it.

     7.    RESERVED SHARES.  The Company warrants that there have
been reserved, and covenants that at all times in the future,  it
shall  keep  reserved, out of the authorized and unissued  Common
Stock,  such  number  of Shares sufficient  to  provide  for  the
exercise  of  the rights of purchase represented by this  Warrant
Certificate.   The Company agrees that all Shares  issuable  upon
exercise of the Warrants shall be, at the time of delivery of the
certificates  for  such Shares, validly issued  and  outstanding,
fully  paid  and  non-assessable and that the  issuance  of  such
Shares  will  not  give rise to preemptive  rights  in  favor  of
existing stockholders.

     8.   DIVIDENDS RECLASSIFICATIONS, ETC.

          (A)   Dividends; Reclassifications, etc.  In the  event
that the Company shall, at any time prior to the exercise of this
Warrant:  (i) declare or pay to the holders of the Common Stock a
dividend  payable in any kind of shares of stock of the  Company;
or (ii) change or divide or otherwise reclassify its Common Stock
into the same or a different number of shares with or without par
value,  or  in shares of any class or classes; or (iii)  transfer
its  property as an entirety or substantially as an  entirety  to
any  other company; (iv) merge with or consolidate with  or  into
any other corporation or entity; or (v) make any distribution  of
its  assets  to  holders of its Common Stock as a liquidation  or
partial  liquidation  dividend or by way of  return  of  capital;
then,  upon  the subsequent exercise of this Warrant, the  Holder
shall  receive, in addition to or in substitution for the  shares
of Common Stock to which it would otherwise be entitled upon such
exercise,  such  additional shares  of  stock  or  scrip  of  the
Company, or such reclassified shares of stock of the Company,  or
such  shares  of  the  securities  or  property  of  the  Company
resulting  from  such transfer, or such assets  of  the  Company,
which  it  would have been entitled to receive had  it  exercised
this  Warrant  prior  to the happening of any  of  the  foregoing
events.

          (B)   Notice of Certain Transactions.  If, at any  time
while  this  Warrant is outstanding, the Company  shall  pay  any
dividend payable in cash or in Common Stock, shall offer  to  the
holders of its Common Stock for subscription or purchase by  them
any  shares of stock of any class or any other rights,  or  shall
enter  into  an  agreement to merge or consolidate  with  another
corporation, the Company shall cause notice thereof to be  mailed
to the registered holder of this Warrant at its address appearing
on  the registration books of the Company, at least 10 days prior
to  the  record  date as of which holders of Common  Stock  shall
participate  in  such dividend, distribution or  subscription  or
other  rights or at least 10 days prior to the effective date  of
the  merger or consolidation.  Failure to give notice as required
by  this  Section, or any defect therein, shall  not  affect  the
legality   or   validity   of  any  dividend,   distribution   or
subscription or other right.

          (C)  Carry Forwards.  Anything in this Section 8 to the
contrary  notwithstanding, no adjustment in  the  Exercise  Price
shall  be  required  unless  such  adjustment  would  require  an
increase  or  decrease  of at least 10% in such  Exercise  Price;
provided, however, that any adjustments which by reason  of  this
Subsection  (C)  are  not required to be made  shall  be  carried
forward  and taken into account in making subsequent adjustments.
All  calculations  under this Section 8  shall  be  made  to  the
nearest cent or to the nearest tenth of a share, as the case  may
be.

          (D)  Notice of Adjustments.  Upon any adjustment of the
Exercise  Price,  then and in each such case  the  Company  shall
promptly  deliver  a  notice  to the registered  Holder  of  this
Warrant,  which  notice shall state the Exercise Price  resulting
from such adjustment and the increase or decrease, if any, in the
number  of  Shares  purchasable at such price upon  the  exercise
hereof,  setting  forth  in  reasonable  detail  the  method   of
calculation and the facts upon which such calculation is based.

     9.   TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.

          (A)   The Holder of this Warrant Certificate, and  each
transferee of any Shares, by his acceptance thereof, agrees  that
(a) no public distribution of Shares will be made in violation of
the  Act,  and  (b)  during such period  as  the  delivery  of  a
prospectus with respect to Shares may be required by the Act,  no
public  distribution of Shares will be made in  a  manner  or  on
terms different from those set forth in, or without delivery  of,
a  prospectus then meeting the requirements of Section 10 of  the
Act and in compliance with applicable state securities laws.  The
Holder  of  this  Warrant Certificate and each transferee  hereof
further agrees that if any distribution of any of the Warrants or
Shares  is proposed to be made by them otherwise than by delivery
of  a  prospectus meeting the requirements of Section 10  of  the
Act,  such  action  shall be taken only after submission  to  the
Company of an opinion of counsel, reasonably satisfactory in form
and  substance to the Company's counsel, to the effect  that  the
proposed distribution will not be in violation of the Act  or  of
applicable  state law.  Furthermore, it shall be a  condition  to
the  transfer of the Warrants that any transferee thereof deliver
to  the  Company his written agreement to accept and be bound  by
all  of  the  terms  and  conditions contained  in  this  Warrant
Certificate.

          (B)  This Shares issued on exercise of this Warrant may
not be sold or otherwise disposed of except as follows:

               (1)   To  a person who, in the opinion of  counsel
for  the Holder reasonably acceptable to the Company, is a person
to  whom  Shares may legally be transferred without  registration
and  without the delivery of a current prospectus under  the  Act
with  respect  thereto  and  then  only  against  receipt  of  an
agreement  of such person to comply with the provisions  of  this
Section  10  with respect to any resale or other  disposition  of
such  securities, which agreement shall be satisfactory  in  form
and  substance to the Company and its counsel; provided that  the
foregoing shall not apply to any such Warrant, Shares as to which
such Holder shall have received an opinion letter from counsel to
the  Company  as  to the exemption thereof from the  registration
under the Act pursuant to Rule 144(k) under the Act; or

               (2)   To  any person upon delivery of a prospectus
then  meeting  the  requirements of  the  Act  relating  to  such
securities and the offering thereof for such sale or disposition.

          (C)   Each  certificate for Shares issued upon exercise
of   this   Warrant   shall  bear  a  legend  relating   to   the
non-registered status of such Shares under the Act, unless at the
time  of  exercise of this Warrant such Shares are subject  to  a
currently effective registration statement under the Act.

     10.  MISCELLANEOUS.

          (A)  Law to Govern.  This Warrant shall be governed  by

State of Pennsylvania, without giving effect to conflict of  laws
principles.
