par value $0.001 per share ("Common Stock"). The Warrant Price shall be adjusted
to $1.50 following the  transactions  (the  "Transactions")  contemplated by the
Subscription  Agreement (as defined  below) and the  Memorandum (as such term is

purchasable upon exercise of this Warrant and the Warrant Price shall be subject
to further adjustment from time to time as described herein.

<PAGE>

         Section 1.  REGISTRATION.  The  Company  shall  maintain  books for the
transfer  and  registration  of the Warrant.  Upon the initial  issuance of this
Warrant,  the Company  shall issue and  register  the Warrant in the name of the
Warrantholder.

         Section  2.  TRANSFERS.   A  provided  herein,   this  Warrant  may  be
transferred only pursuant to a registration statement filed under the Securities
Act of 1933,  as amended  (the  "Securities  Act"),  or an  exemption  from such
registration.  Subject to such  restrictions,  the Company  shall  transfer this
Warrant  from time to time upon the books to be  maintained  by the  Company for
that  purpose,   upon  surrender  thereof  for  transfer  properly  endorsed  or
accompanied by appropriate instructions for transfer and such other documents as
may be  reasonably  required  by the  Company,  including,  if  required  by the
Company,  an opinion  of the  Warrantholders'  counsel  to the effect  that such
transfer is exempt from the registration  requirements of the Securities Act, to
establish that such transfer is being made in accordance  with the terms hereof,
and a new Warrant shall be issued to the transferee and the surrendered  Warrant
shall be canceled by the Company.

         Section 3. EXERCISE OF WARRANT.  Subject to the provisions  hereof, the
Warrantholder  may exercise the Warrant in whole or in part at any time prior to
its expiration upon surrender of the Warrant, together with delivery of the duly
executed  Warrant  exercise  form attached  hereto as Appendix A (the  "Exercise
Agreement")  and payment by cash,  certified check or wire transfer of funds for
the  aggregate  Warrant  Price for that  number of  Warrant  Shares  then  being
purchased,  to the Company  during normal  business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may designate by notice to the Warrantholder).  The Warrant Shares
so  purchased  shall  be  deemed  to be  issued  to  the  Warrantholder  or  the
Warrantholder's  designees,  as the record owner of such shares, as of the close
of business on the date on which this Warrant  shall have been  surrendered  (or
evidence  of loss,  theft or  destruction  thereof  and  security  or  indemnity
satisfactory  to the  Company),  the Warrant  Price shall have been paid and the
completed  Exercise  Agreement shall have been delivered.  Certificates  for the
Warrant  Shares  so  purchased,  representing  the  aggregate  number  of shares
specified in the  Exercise  Agreement,  shall be delivered to the  Warrantholder
within reasonable time, not exceeding five (5) business days, after this Warrant
shall have been so exercised.  The  certificates  so delivered  shall be in such
denominations as may be requested by the  Warrantholder  and shall be registered
in the name of the  Warrantholder  or such other name as shall be  designated by
the Warrantholder. If this Warrant shall have been exercised only in part, then,
unless this Warrant has expired,  the Company shall, at its expense, at the time
of delivery of such  certificates,  deliver to the  Warrantholder  a new Warrant
representing  the number of shares with  respect to which the Warrant  shall not
then have been exercised. As used herein, "business day" means a day, other than
a Saturday  or Sunday,  on which banks in New York City are open for the general
transaction   of  business.   Each   exercise   hereof  shall   constitute   the
re-affirmation  by the  Warrantholder  that the  representations  and warranties
contained  in  Article  1  of  the  Subscription  Agreement  (the  "Subscription
Agreement") dated April 27, 2005 between the Company and the Subscribers thereto
are true and correct in all material  respects with respect to the Warrantholder
as of the time of such exercise.

         Section  4.  COMPLIANCE  WITH THE  SECURITIES  ACT OF 1933.  Except  as
provided  in the  Subscription  Agreement,  the Company may cause the legend set
forth on the  first  page of this  Warrant  to be set forth on each  Warrant  or
similar legend on any security issued or issuable upon exercise of this Warrant,
unless  counsel for the Company is of the opinion as to any such  security  that
such legend is unnecessary.

                                       2
<PAGE>

         Section 5. PAYMENT OF TAXES. The Company will pay any documentary stamp
taxes  attributable to the initial  issuance of Warrant Shares issuable upon the
exercise  of the  Warrant;  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 Warrant Shares in a
name other than that of the  Warrantholder  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 Warrant 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  reasonable  satisfaction  that  such  tax  has  been  paid.  The
Warrantholder shall be responsible for income taxes due under federal,  state or
other law, if any such tax is due.

         Section 6. MUTILATED OR MISSING WARRANTS. In case this Warrant shall be
mutilated,  lost, stolen, or destroyed,  the Company shall issue in exchange and
substitution of and upon  cancellation of the mutilated  Warrant,  or in lieu of
and  substitution  for the Warrant lost,  stolen or destroyed,  a new Warrant of
like tenor and for the  purchase  of a like number of Warrant  Shares,  but only
upon receipt of evidence  reasonably  satisfactory  of the Company of such loss,
theft or  destruction  of the  Warrant,  and with  respect to a lost,  stolen or
destroyed  Warrant,  reasonable  indemnity  or bond  with  respect  thereto,  if
requested by the Company.

         Section 7.  RESERVATION OF COMMON STOCK.  The Company hereby  covenants
that  within  forty-five  (45) days of the date of this  Warrant,  there will be
reserved, and the Company shall at all applicable times thereafter keep reserved
until  issued  (if  necessary)  as  contemplated  by this  Section 7, out of the
authorized and unissued shares of Common Stock, sufficient shares to provide for
the  exercise  of the  rights  of  purchase  represented  by this  Warrant.  The
Warrantholder shall not exercise this Warrant within such forty-five day period.
Company  agrees that all Warrant  Shares issued upon due exercise of the Warrant
shall be, at the time of delivery of the  certificates  for such Warrant Shares,
duly authorized,  validly issues, fully paid and non-assessable shares of Common
Stock of the Company.

         Section 8. ADJUSTMENTS.  Subject and pursuant to the provisions of this
Section 8, unless waived in a particular case by the Warrantholder,  the Warrant
Price and number of Warrant  Shares  subject to this Warrant shall be subject to
adjustment from time to time as set forth hereinafter.

                  (a) If the  Company  shall,  at any time or from  time to time
while this Warrant is outstanding,  pay a dividend or make a distribution on its
Common Stock in shares of Common  Stock,  subdivide  its  outstanding  shares of
Common Stock into a greater number of shares or combine its  outstanding  shares
of Common Stock into a smaller number of shares or issue by  reclassification of
its  outstanding  shares  of  Common  Stock  any  shares  of its  capital  stock
(including  any such  reclassification  in connection  with a  consolidation  or
merger in which the Company is continuing the  corporation),  then the number of
Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in
effect  immediately  prior to the date  upon  which  such  change  shall  become
effective, shall be adjusted by the Company so that the Warrantholder thereafter
exercising  the  Warrant  shall be  entitled  to receive the number of shares of
Common Stock or other capital stock which the Warrantholder  would have received
if the Warrant had been exercised  immediately  prior to such event upon payment
of the Warrant Price. Such adjustments  shall be made successively  whenever any
event  listed  above  shall   occur.

                                       3
<PAGE>

                  (b)  Anything  herein  to the  contrary  notwithstanding,  the
Company shall not be required to make any adjustment to the Warrant Price in the
case of the issuance of (A) capital  stock,  options or  convertible  securities
issued to  directors,  officers,  employees  or  consultants  of the  Company in
connection with their service as directors of the Company,  their  employment by
the Company or their  retention  as  consultants  by the Company  pursuant to an
equity compensation program approved by the Board of Directors of the Company or
the compensation  committee of the Board of Directors of the Company, (B) shares
of the  Common  Stock  issued  upon the  conversion  or  exercise  of options or
convertible  securities  issued prior to the date hereof,  (C) securities issued
pursuant  to the  Subscription  Agreement  and the  securities  issued  upon the
exercise  or  conversion  of those  securities,  and (D) shares of Common  Stock
issued or issuable by reason of a dividend, stock spilt or other distribution on
shares of Common  Stock (but only to the extent that such a  dividend,  split or
distribution results in an adjustment in the Warrant Price pursuant to the other
provisions of this Warrant) (collectively, "Excluded Issuances").

         Section 9.  FRACTIONAL  INTEREST.  The Company shall not be required to
issue  fractions  of Warrant  Shares upon the exercise of this  Warrant.  If any
fractional  share of Common Stock would,  except for the provisions of the first
sentence of this Section 9, be deliverable upon such exercise,  the Company,  in
lieu  of  delivering  such  fractional  share,   shall  pay  to  the  exercising
Warrantholder  an amount in cash  equal to the Market  Price of such  fractional
share of Common Stock on the date of exercise.

         Section 10.  BENEFITS.  Nothing in this  Warrant  shall be construed to
give  any  person,   firm  or  corporation  (other  than  the  Company  and  the
Warrantholder)  any legal or equitable  right,  remedy or claim, it being agreed
that this Warrant shall be for the sole and exclusive benefit of the Company and
the Warrantholder.

         Section 11. NOTICES TO  WARRANTHOLDER.  Upon the happening of any event
requiring an adjustment of the Warrant  Price,  the Company shall  promptly give
written  notice  thereof to the  Warrantholder  at the address  appearing in the
records of the  Company,  stating the  adjusted  Warrant  Price and the adjusted
number of  Warrant  Shares  resulting  from  such  event  and  setting  forth in
reasonable  detail  the  method of  calculation  and the facts  upon  which such
calculation is based.  Failure to give such notice to the  Warrantholder  or any
defect  therein  shall not  affect  the  legality  or  validity  of the  subject
adjustment.

         Section 12. NOTICES.  Unless otherwise provided, any notice required or
permitted  under  this  Warrant  shall be given in  writing  and shall be deemed
effectively  given as hereinafter  described (i) if given by personal  delivery,
then such  notice  shall be deemed  given upon such  delivery,  (ii) if given by
telex or  facsimile,  then such  notice  shall be deemed  given upon  receipt of
confirmation of complete  transmittal,  (iii) if given by mail, then such notice
shall be deemed  given  upon the  earlier of (A)  receipt of such  notice by the
recipient  or (B) three days after such notice is deposited in first class mail,
postage prepaid,  and (iv) if given by an internationally  recognized  overnight
air  courier,  then such notice  shall be deemed  given one  business  day after
delivery to such carrier.  All notices shall be addressed as follows:  if to the
Warrantholder,  at its address as set forth in the  Company's  books and records
and, if to the Company,  at the address as follows,  or at such other address as
the  Warrantholder  or the Company may  designate by ten days'  advance  written

of the Company  under this Warrant  shall be assumed by U.S.  Telesis  Holdings,
Inc.  ("UST")  pursuant  to a  Stock  Exchange  Agreement  between  the  initial
Warrantholder  and UST as more fully  described  in the  Subscription  Agreement
executed by the  Warrantholder.  In  addition,  the common stock of UST issuable

with the Stock Exchange Agreement.  Any subsequent Warrantholder may be entitled
to such rights.

         Section 14.  SUCCESSORS.  All the covenants and provisions hereof by or
for the benefit of the Warrantholder  shall bind and inure to the benefit of its
respective successors and assigns hereunder.

         Section 15. GOVERNING LAW;  CONSENT TO JURISDICTION;  WAIVER OF JURY BY
TRIAL.  This Warrant shall be governed by, and construed in accordance with, the
internal laws of the State of New York,  without  reference to the choice of law
provisions   thereof.   The  Company  and,  by  accepting   this  Warrant,   the

anywhere  in the world by the same  methods as are  specified  for the giving of
notices under this  Warrant.  The Company and, by accepting  this  Warrant,  the
Warrantholder,  each irrevocably  consents to the jurisdiction of any such court
in any such suit, action or proceeding and to the laying of venue in such court.
The Company and, by accepting this Warrant, the Warrantholder,  each irrevocably
waives  any  objection  to the  laying  of  venue of any such  suit,  action  or
proceeding brought in such courts and irrevocably waives any claim that any such
suit,  action or  proceeding  brought in any such  court has been  brought in an
inconvenient  forum.  EACH OF THE COMPANY  AND, BY ITS  ACCEPTANCE  HEREOF,  THE
WARRANTHOLDER  HEREBY  WAIVES  ANY  RIGHT  TO  REQUEST  A  TRIAL  BY JURY IN ANY
LITIGATION  WITH  RESPECT TO THIS  WARRANT AS  REPRESENTS  THAT COUNSEL HAS BEEN
CONSULTED SPECIFICALLY AS TO THIS WAIVER.

         Section 16. CALL PROVISIONS.

                  (a)  Subject to the  provisions  of clauses (b) and (c) below,
from time to time at any time that the closing bid of a share of Common Stock as
traded on the  Over-the-Counter  Bulletin Board (or such other exchange or stock
market on which the Common Stock may then be listed or quoted) equals or exceeds
$34.74 (which amount shall be adjusted to $2.50 following the  Transactions  and
thereafter  approximately  adjusted  for any stock split,  reverse  stock split,
stock  dividend or other  reclassification  or  combination  of the Common Stock
occurring after the Transactions,  collectively,  a  "Reclassification")  for at
least ten (10) consecutive trading days with an average daily volume of at least
2,879 shares (which  volume amount shall be adjusted to 40,000 shares  following
the Transactions and thereafter approximately adjusted for any Reclassification)
during such ten (10)  consecutive  trading days and during which a  registration
statement (as required by the Registration  Rights Agreement) has been effective
(the  "TRADING  CONDITION"),  the Company,  upon twenty (20) days prior  written
notice  (the  "NOTICE  PERIOD")  given to the  Warrantholder,  may  require  the
Warrantholder  to exercise  the Warrant at the Warrant

                                       6
<PAGE>

Price. In the event the Warrantholder  shall fail to exercise the Warrant at the
Warrant  Price  within  the Notice  Period,  the  Company  shall have the right,
without further notice to call this Warrant at a redemption price equal to $0.01
per  share  of  Common   Stock  then   purchasable   pursuant  to  the  Warrant.
Notwithstanding any such notice by the Company, the Warrantholder shall have the
right to  exercise  this  Warrant  in  whole or in part  prior to the end of the
Notice Period.

                  (b) In  connection  with any transfer of less than all of this
Warrant,  the  transferring  Warrantholder  shall  deliver  to  the  Company  an
agreement or instrument  executed by the transferring  Warrantholder and the new
Warrantholder  allocating  between them on whatever  basis they may determine in
their sole  discretion any subsequent  call of the Warrant by the Company,  such
that after giving  effect to such  transfer the Company  shall have the right to
call the same  number of  Warrants  that it would  have had if the  transfer  or
exchange had not occurred.

         Section  17. NO RIGHTS AS  STOCKHOLDER.  Prior to the  exercise of this
Warrant,  the  Warrantholder  shall  not  have  or  exercise  any  rights  as  a
stockholder of the Company by virtue of its ownership of this Warrant.

         Section  18.  AMENDMENT;  WAIVER.  This  Warrant  is one of a class  of
Warrants  of like  tenor  issued by the  Company  pursuant  to the  Subscription
Agreement and initially  covering an aggregate of 162,013 shares of Common Stock
(collectively the "Company  Warrants").  Any term of this Warrant may be amended
or waived upon the written consent of the Company and the holders of the Company
Warrants  representing at least 50% of the number of shares of Common Stock then
subject to all outstanding Company Warrants (the "Majority Holders");  PROVIDED,
that (x) any such amendment or waiver must apply to all Company  Warrants of the
same tenor;  and (y) the number of Warrant Shares  subject to this Warrant,  the
Warrant  Price  and the  Expiration  Date may not be  amended,  and the right to
exercise this Warrant may not be altered or waived,  without the written consent
of the Warrantholder.

         Section 19.  ACQUISITION.  As described in the Offering  Materials  (as
such term is  defined in the  Subscription  Agreement),  all of the  outstanding
capital  stock  of the  Company  shall  be  acquired  by UST and  all  warrants,
including  this  Warrant to purchase  the common  stock of the Company  shall be
assumed  by UST  (the  "Acquisition").  Accordingly,  upon  consummation  of the
Acquisition and subject to the terms and conditions  hereof,  the  Warrantholder
shall have the right to exercise  this  Warrant to receive such number of shares
of UST to which the  Warrantholder  would have been entitled as consideration in
the  Acquisition  if the  Warrantholder  had  exercised  this Warrant to receive
Common Stock immediately prior to the Acquisition.

         Section 20. SECTION HEADINGS.  The section headings in this Warrant are
for the  convenience of the Company and the  Warrantholder  and in no way alter,
modify, amend, limit or restrict the provisions hereof.

                                  CATCHER, INC.

                      WARRANT TO PURCHASE ______ SHARES OF
                    COMMON STOCK, PAR VALUE $0.001 PER SHARE

For VALUE RECEIVED, _____________________________ ("Warrantholder"), is entitled
to purchase,  subject to the provisions of this Warrant,  from Catcher,  Inc., a
Delaware  corporation  (the  "Company"),  at any time not later  than 5:00 P.M.,
Eastern time, on the Expiration  Date (as defined  above),  at an exercise price
per share equal to $27.78 (the exercise  price in effect being herein called the
"Warrant  Price"),  ______ shares  ("Warrant  Shares") of the  Company's  Common
Stock, par value $0.001 per share ("Common  Stock").  The Warrant Price shall be
adjusted to $2.00 following the transactions (the  "Transactions")  contemplated
by the  Subscription  Agreement (as defined  below) and the  Memorandum (as such
term is described in the Subscription  Agreement).  The number of Warrant Shares
purchasable upon exercise of this Warrant and the Warrant Price shall be subject
to further adjustment from time to time as described herein.

         Section 1.  REGISTRATION.  The  Company  shall  maintain  books for the
transfer  and  registration  of the Warrant.  Upon the initial  issuance of this
Warrant,  the Company  shall issue and  register  the Warrant in the name of the
Warrantholder.

         Section  2.  TRANSFERS.   A  provided  herein,   this  Warrant  may  be
transferred only pursuant to a registration statement filed under the Securities
Act of 1933,  as amended  (the  "Securities  Act"),  or an  exemption  from such
registration.  Subject to such  restrictions,  the Company  shall  transfer this
Warrant  from time to time upon the books to be  maintained  by the  Company for
that  purpose,   upon  surrender  thereof  for  transfer  properly  endorsed  or
accompanied by appropriate instructions for transfer and such other documents as
may be  reasonably  required  by the  Company,  including,  if  required  by the
Company, an opinion of Warrantholders'  counsel to the effect that such transfer
is exempt from the registration requirements of the Securities Act, to establish
that such transfer is being made in accordance with the terms hereof,  and a new
Warrant shall be issued to the transferee and the  surrendered  Warrant shall be
canceled by the Company.

         Section 3. EXERCISE OF WARRANT.  Subject to the provisions  hereof, the
Warrantholder  may exercise the Warrant in whole or in part at any time prior to
its expiration upon surrender of

<PAGE>

the Warrant,  together with delivery of the duly executed  Warrant exercise form
attached  hereto as Appendix A (the "Exercise  Agreement")  and payment by cash,
certified  check or wire transfer of funds for the  aggregate  Warrant Price for
that number of Warrant Shares then being purchased, to the Company during normal
business hours on any business day at the Company's  principal executive offices
(or such other office or agency of the Company as it may  designate by notice to
the Warrantholder). The Warrant Shares so purchased shall be deemed to be issued
to the Warrantholder or the  Warrantholder's  designees,  as the record owner of
such shares, as of the close of business on the date on which this Warrant shall
have been  surrendered  (or evidence of loss,  theft or destruction  thereof and
security or indemnity satisfactory to the Company), the Warrant Price shall have
been paid and the  completed  Exercise  Agreement  shall  have  been  delivered.
Certificates  for the Warrant  Shares so purchased,  representing  the aggregate
number of shares specified in the Exercise Agreement,  shall be delivered to the
Warrantholder  within  reasonable  time,  not exceeding  five (5) business days,
after this Warrant shall have been so exercised.  The  certificates so delivered
shall be in such  denominations  as may be  requested by the  Warrantholder  and
shall be registered in the name of the Warrantholder or such other name as shall
be designated by the  Warrantholder.  If this Warrant shall have been  exercised
only in part, then,  unless this Warrant has expired,  the Company shall, at its
expense,  at  the  time  of  delivery  of  such  certificates,  deliver  to  the
Warrantholder  a new Warrant  representing  the number of shares with respect to
which the Warrant shall not then have been exercised. As used herein,  "business
day" means a day,  other than a Saturday  or Sunday,  on which banks in New York
City are open for the general  transaction  of business.  Each  exercise  hereof
shall   constitute   the   re-affirmation   by  the   Warrantholder   that   the
representations  and  warranties  contained  in  Article  1 of the  Subscription
Agreement  (the  "Subscription  Agreement")  dated  April __,  2005  between the
Company  and the  Subscribers  thereto  are true  and  correct  in all  material
respects  with  respect to the  Warrantholder  as of the time of such  exercise.

         Section  4.  COMPLIANCE  WITH THE  SECURITIES  ACT OF 1933.  Except  as
provided  in the  Subscription  Agreement,  the Company may cause the legend set
forth on the  first  page of this  Warrant  to be set forth on each  Warrant  or
similar legend on any security issued or issuable upon exercise of this Warrant,
unless  counsel for the Company is of the opinion as to any such  security  that
such legend is unnecessary.

         Section 5. PAYMENT OF TAXES. The Company will pay any documentary stamp
taxes  attributable to the initial  issuance of Warrant Shares issuable upon the
exercise  of the  Warrant;  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 Warrant Shares in a
name other than that of the  Warrantholder  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 Warrant 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  reasonable  satisfaction  that  such  tax  has  been  paid.  The
Warrantholder shall be responsible for income taxes due under federal,  state or
other law, if any such tax is due.

         Section 6. MUTILATED OR MISSING WARRANTS. In case this Warrant shall be
mutilated,  lost, stolen, or destroyed,  the Company shall issue in exchange and
substitution of and upon  cancellation of the mutilated  Warrant,  or in lieu of
and  substitution  for the Warrant lost,  stolen or destroyed,  a new Warrant of
like tenor and for the  purchase  of a like number of Warrant  Shares,  but only
upon receipt of evidence  reasonably  satisfactory  of the Company of such loss,
theft or

                                       2
<PAGE>

destruction  of the  Warrant,  and with  respect to a lost,  stolen or destroyed
Warrant,  reasonable indemnity or bond with respect thereto, if requested by the
Company.

         Section 7.  RESERVATION OF COMMON STOCK.  The Company hereby  covenants
that  within  forty  five (45) days of the date of this  Warrant,  there will be
reserved, and the Company shall at all applicable times thereafter keep reserved
until  issued  (if  necessary)  as  contemplated  by this  Section 7, out of the
authorized and unissued shares of Common Stock, sufficient shares to provide for
the  exercise  of the  rights  of  purchase  represented  by this  Warrant.  The
Warrantholder shall not exercise this Warrant within such forty-five day period.
The  Company  agrees  that all Warrant  Shares  issued upon due  exercise of the
Warrant shall be, at the time of delivery of the  certificates  for such Warrant
Shares, duly authorized, validly issues, fully paid and non-assessable shares of
Common Stock of the Company.

         Section 8. ADJUSTMENTS.  Subject and pursuant to the provisions of this
Section 8, unless waived in a particular case by the Warrantholder,  the Warrant
Price and number of Warrant  Shares  subject to this Warrant shall be subject to
adjustment from time to time as set forth hereinafter.

                  (a) If the  Company  shall,  at any time or from  time to time
while this Warrant is outstanding,  pay a dividend or make a distribution on its
Common Stock in shares of Common  Stock,  subdivide  its  outstanding  shares of
Common Stock into a greater number of shares or combine its  outstanding  shares
of Common Stock into a smaller number of shares or issue by  reclassification of
its  outstanding  shares  of  Common  Stock  any  shares  of its  capital  stock
(including  any such  reclassification  in connection  with a  consolidation  or
merger in which the Company is continuing the  corporation),  then the number of
Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in
effect  immediately  prior to the date  upon  which  such  change  shall  become
effective, shall be adjusted by the Company so that the Warrantholder thereafter
exercising  the  Warrant  shall be  entitled  to receive the number of shares of
Common Stock or other capital stock which the Warrantholder  would have received
if the Warrant had been exercised  immediately  prior to such event upon payment
of the Warrant Price. Such adjustments  shall be made successively  whenever any
event listed above shall occur.

                  (b)  Anything  herein  to the  contrary  notwithstanding,  the
Company shall not be required to make any adjustment to the Warrant Price in the
case of the issuance of (A) capital  stock,  Options or  Convertible  Securities
issued to  directors,  officers,  employees  or  consultants  of the  Company in
connection with their service as directors of the Company,  their  employment by
the Company or their  retention  as  consultants  by the Company  pursuant to an
equity compensation program approved by the Board of Directors of the Company or
the compensation  committee of the Board of Directors of the Company, (B) shares
of the  Common  Stock  issued  upon the  conversion  or  exercise  of Options or
Convertible  Securities  issued prior to the date hereof,  (C) securities issued
pursuant  to the  Subscription  Agreement  and the  securities  issued  upon the
exercise  or  conversion  of those  securities,  and (D) shares of Common  Stock
issued or issuable by reason of a dividend, stock spilt or other distribution on
shares of Common  Stock (but only to the extent that such a  dividend,  split or
distribution results in an adjustment in the Warrant Price pursuant to the other
provisions of this Warrant) (collectively, "Excluded Issuances").

         Section 9.  FRACTIONAL  INTEREST.  The Company shall not be required to
issue  fractions  of Warrant  Shares upon the exercise of this  Warrant.  If any
fractional  share of Common Stock

                                       3
<PAGE>

would,  except for the  provisions  of the first  sentence of this Section 9, be
deliverable  upon  such  exercise,  the  Company,  in  lieu of  delivering  such
fractional  share,  shall pay to the exercising  Warrantholder an amount in cash
equal to the Market Price of such  fractional  share of Common Stock on the date
of exercise.

         Section 10.  BENEFITS.  Nothing in this  Warrant  shall be construed to
give  any  person,   firm  or  corporation  (other  than  the  Company  and  the
Warrantholder)  any legal or equitable  right,  remedy or claim, it being agreed
that this Warrant shall be for the sole and exclusive benefit of the Company and
the Warrantholder.

         Section 11. NOTICES TO  WARRANTHOLDER.  Upon the happening of any event
requiring an adjustment of the Warrant  Price,  the Company shall  promptly give
written  notice  thereof to the  Warrantholder  at the address  appearing in the
records of the  Company,  stating the  adjusted  Warrant  Price and the adjusted
number of  Warrant  Shares  resulting  from  such  event  and  setting  forth in
reasonable  detail  the  method of  calculation  and the facts  upon  which such
calculation is based.  Failure to give such notice to the  Warrantholder  or any
defect  therein  shall not  affect  the  legality  or  validity  of the  subject
adjustment.

         Section 12. NOTICES.  Unless otherwise provided, any notice required or
permitted  under  this  Warrant  shall be given in  writing  and shall be deemed
effectively  given as hereinafter  described (i) if given by personal  delivery,
then such  notice  shall be deemed  given upon such  delivery,  (ii) if given by
telex or  facsimile,  then such  notice  shall be deemed  given upon  receipt of
confirmation of complete  transmittal,  (iii) if given by mail, then such notice
shall be deemed  given  upon the  earlier of (A)  receipt of such  notice by the
recipient  or (B) three days after such notice is deposited in first class mail,
postage prepaid,  and (iv) if given by an internationally  recognized  overnight
air  courier,  then such notice  shall be deemed  given one  business  day after
delivery to such carrier.  All notices shall be addressed as follows:  if to the
Warrantholder,  at its address as set forth in the  Company's  books and records
and, if to the Company,  at the address as follows,  or at such other address as
the  Warrantholder  or the Company may  designate by ten days'  advance  written

from time to time at any time that the closing bid of a share of Common Stock as
traded on the  Over-the-Counter  Bulletin Board (or such other exchange or stock
market on which the Common Stock may then be listed or quoted) equals or exceeds
$45.14 (which amount shall be adjusted to $3.33 following the  Transactions  and
thereafter  approximately  adjusted  for any stock split,  reverse  stock split,
stock  dividend or other  reclassification  or  combination  of the Common Stock
occurring after the Transactions,  collectively,  a  "Reclassification")  for at
least ten (10) consecutive trading days with an average daily volume of at least
2,879 shares (which  volume amount shall be adjusted to 40,000 shares  following
the Transactions and thereafter approximately adjusted for any Reclassification)
during such ten (10)  consecutive  trading days and during which a  registration
statement (as required by the Registration  Rights Agreement) has been effective
(the  "TRADING  CONDITION"),  the Company,  upon twenty (20) days prior  written
notice  (the  "NOTICE  PERIOD")  given to the  Warrantholder,  may  require  the
Warrantholder  to exercise the Warrant in whole or in part at the Warrant Price.
In the event the Warrantholder shall fail to exercise the Warrant at the Warrant
Price  within the  Notice  Period,  the  Company  shall have the right,  without
further  notice to call this  Warrant at a  redemption  price equal to $0.01 per
share of Common Stock then purchasable pursuant to the Warrant.  Notwithstanding
any such  notice  by the  Company,  the

                                       5
<PAGE>

Warrantholder  shall have the right to exercise this Warrant in whole or in part
prior to the end of the Notice Period.

                  (b) In  connection  with any transfer of less than all of this
Warrant,  the  transferring  Warrantholder  shall  deliver  to  the  Company  an
agreement or instrument  executed by the transferring  Warrantholder and the new
Warrantholder  allocating  between them on whatever  basis they may determine in
their sole  discretion any subsequent  call of the Warrant by the Company,  such
that after giving  effect to such  transfer the Company  shall have the right to
call the same  number of  Warrants  that it would  have had if the  transfer  or
exchange had not occurred.

         Section  17. NO RIGHTS AS  STOCKHOLDER.  Prior to the  exercise of this
Warrant,  the  Warrantholder  shall  not  have  or  exercise  any  rights  as  a
stockholder  of the Company by virtue of its ownership of this Warrant.

         Section  18.  AMENDMENT;  WAIVER.  This  Warrant  is one of a class  of
Warrants  of like  tenor  issued by the  Company  pursuant  to the  Subscription
Agreement and initially  covering an aggregate of 162,013 shares of Common Stock
(collectively the "COMPANY  WARRANTS").  Any term of this Warrant may be amended
or waived upon the written consent of the Company and the holders of the Company
Warrants  representing at least 50% of the number of shares of Common Stock then
subject to all outstanding Company Warrants (the "MAJORITY HOLDERS");  PROVIDED,
that (x) any such  amendment or waiver must apply to all Company  Warrants;  and
(y) the number of Warrant Shares subject to this Warrant,  the Warrant Price and
the Expiration  Date may not be amended,  and the right to exercise this Warrant
may not be altered or waived, without the written consent of the Warrantholder.

         Section 19.  ACQUISITION.  As described in the Offering  Materials  (as
such term is  defined in the  Subscription  Agreement),  all of the  outstanding
capital  stock  of the  Company  shall  be  acquired  by UST and  all  warrants,
including  this  Warrant to purchase  the common  stock of the Company  shall be
assumed  by UST  (the  "Acquisition").  Accordingly,  upon  consummation  of the
Acquisition and subject to the terms and conditions  hereof,  the  Warrantholder
shall have the right to exercise  this  Warrant to receive such number of shares
of UST to which the  Warrantholder  would have been entitled as consideration in
the  Acquisition  if the  Warrantholder  had  exercised  this Warrant to receive
Common Stock immediately prior to the Acquisition.

         Section 20. SECTION HEADINGS.  The section headings in this Warrant are
for the  convenience of the Company and the  Warrantholder  and in no way alter,
modify, amend, limit or restrict the provisions hereof.
