 3.  FORM AND EXECUTION OF WARRANT CERTIFICATES

     (a) The Class A Warrant  Certificates  shall be  substantially  in the form
annexed  hereto as Exhibit A (the  provisions  of which are hereby  incorporated
herein) and may have such letters,  numbers, or other marks of identification or
designation and such legends, summaries, or endorsements printed,  lithographed,
or  engraved  thereon  as the  Company  may  deem  appropriate  and  as are  not
inconsistent  with the  provisions of this  Agreement,  or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or  regulation  of any  stock  exchange  on which the  Warrants  may be
listed,  or to conform  to usage or to the  requirements  of Section 2 (b).  The
Warrant  Certificates  shall be dated the date of issuance thereof (whether upon
initial issuance,  transfer, exchange, or in lieu of mutilated, lost, stolen, or
destroyed  Warrant   Certificates)  and  issued  in  registered  form.   Warrant
Certificates shall be numbered serially with the letter W.

     (b) Warrant  Certificates shall be executed on behalf of the Company by its
Chairman of the Board,  President, or any Vice President and by its Secretary or
an Assistant Secretary,  by manual signatures or by facsimile signatures printed
thereon,  and shall have  imprinted  thereon a facsimile of the Company's  seal.
Warrant  Certificates  shall be manually  countersigned by the Warrant Agent and
shall not be valid for any purpose unless so countersigned.  In case any officer
of the Company who shall have signed any of the Warrant Certificates shall cease
to be an officer of the Company or to hold the particular  office referenced in
the Warrant Certificate before the date of issuance of the Warrant  Certificates
or before  countersignature by the Warrant Agent and issue and delivery thereof,
such Warrant  Certificates  may  nevertheless  be  countersigned  by the Warrant
Agent,  issued and delivered with the same force and effect as though the person
who  signed  such  Warrant  Certificates  had not ceased to be an officer of the
Company or to hold such office.  After  countersignature  by the Warrant  Agent,
Warrant  Certificates  shall be delivered by the Warrant Agent to the Registered
Holder without  further action by the Company,  except as otherwise  provided by
Section 4 hereof.




     4.  EXERCISE.  (a) Each Class A Warrant may be exercised by the  Registered
Holder  thereof at any time on or after the Initial  Warrant  Exercise Date, but
not after the  Warrant  Expiration  Date,  upon the  terms  and  subject  to the
conditions set forth herein and in the applicable Warrant Certificate. A Warrant
shall be  deemed  to have  been  exercised  immediately  prior  to the  close of
business on the Exercise Date and the person  entitled to receive the securities
deliverable  upon such exercise  shall be treated for all purposes as the holder
of those securities upon the exercise of the Warrant as of the close of business
on the Exercise  Date. As soon as  practicable on or after the Exercise Date the
Warrant Agent shall deposit in a non-interest  bearing  account at Chemical Bank
or such other bank as the Warrant  Agent may  designate,  the proceeds  received
from the  exercise of a Warrant  and shall  notify the Company in writing of the
exercise of the Warrants.  Promptly following, and in any event within five days
after the date of such notice  from the Warrant  Agent,  the Warrant  Agent,  on
behalf of the  Company,  shall cause to be issued and  delivered by the Transfer
Agent,  to the person or persons  entitled to receive the same, a certificate or
certificates  for  the  securities   deliverable  upon  such  exercise  (plus  a
certificate for any remaining  unexercised  Warrants of the Registered  Holder),
unless  prior to the date of issuance  of such  certificates  the Company  shall
instruct the Warrant Agent to refrain from causing such issuance of certificates
pending  clearance of checks  received in payment of the Purchase Price pursuant
to such  Warrants.  Upon the exercise of any Warrant and  clearance of the funds
received,  the Warrant Agent shall promptly  remit the payment  received for the
Warrant (the "Warrant  Proceeds") to the Company or as the Company may direct in
writing.

     (b) If,  subsequent  to August 6, 1997,  in respect of the  exercise of any
Warrant,  (i) the market price of the Company's Common Stock is greater than the
then  Purchase  Price of the  Warrants,  (ii) the  exercise  of the  Warrant was
solicited by a member of the National  Association of Securities  Dealers,  Inc.
("NASD") and such member was designated in writing by the holder of such Warrant
as  having  solicited  such  Warrant,  (iii)  the  Warrant  was  not  held  in a
discretionary  account,  (iv) disclosure of compensation  arrangements  was made
both at the time of the  original  offering  and at the time of exercise and (v)
the  solicitation  of the  exercise of the Warrant was not in  violation of Rule
l0b-6  (as such rule or any  successor  rule may be in effect as of such time of
exercise)  promulgated  under the  Securities  Exchange Act of 1934, as amended,
then the Warrant Agent,  simultaneously with the distribution of proceeds to the
Company  received upon exercise of the Warrant(s) so exercised  shall, on behalf
of  the Company, pay from the proceeds received upon exercise of the Warrant(s),
a fee of 8% of the Purchase  Price to Patterson (of which 1% may be reallowed to
the dealer who solicited the exercise, which may also be Patterson). Within five
days after  exercise  of the Warrant  Agent  shall send  Patterson a copy of the
reverse side of each Warrant  exercised.  Patterson  shall reimburse the Warrant
Agent,  upon request,  for its reasonable  expenses  relating to compliance with
this  Section.  addition,  Patterson  and the  Company  may at any  time  during
business hours,  examine the records of the Warrant Agent,  including its ledger
of original  Warrant  Certificates  returned the Warrant  Agent upon exercise of
Warrants.  The  provisions  of this  paragraph  may not be modified,  amended or
deleted without the prior written consent of Patterson.

     5. RESERVATION OF SHARES; LISTING; PAYMENT OF TAXES, ETC.

     (a) The  Company  covenants  that it will at all  times  reserve  and  keep
available out of its  authorized  Common Stock,  solely for the purpose of issue
upon  exercise of Warrants,  such number of shares of Common Stock as shall then
be issuable upon the exercise of all outstanding Warrants. The Company covenants
that all shares of Common  Stock which shall be  issuable  upon  exercise of the
Warrants shall, at the time of delivery, be duly and validly issued, fully paid,
nonassessable,  and free from all taxes,  liens, and charges with respect to the
issue  thereof,  (other  than  those which the Company  shall  promptly  pay or
discharge)  and that upon  issuance such shares shall be listed on each national
securities  exchange or  eligible  for  inclusion  in each  automated  quotation
system,  if any, on which the other  shares of  outstanding  Common Stock of the
Company are then listed or eligible for inclusion.

     (b) The Company  covenants  that if any  securities  to be reserved for the
purpose of exercise of Warrants hereunder require registration with, or approval
of, any  governmental  authority  under any federal  securities  law before such
securities  may be validly  issued or  delivered  upon such  exercise,  then the
Company will in good faith and as expeditiously as reasonably possible, endeavor
to secure such  registration or approval and will use its reasonable  efforts to
obtain appropriate  approvals or registrations under state "blue sky" securities
laws, provided,  however, that the Company shall not be required to qualify as a
foreign corporation or a dealer in securities or to execute a general consent of
service of process in any  jurisdiction.  With  respect to any such  securities,
however,  Warrants may not be exercised by, or shares of Common Stock issued to,
any Registered Holder in any state in which such exercise would be unlawful.

     (c) The Company  shall pay all  documentary,  stamp,  or similar  taxes and
other  governmental  charges that may be imposed with respect to the issuance of
Warrants,  or the  issuance,  or  delivery  of any shares  upon  exercise of the
Warrants;  provided,  however,  that if the  shares  of  Common  Stock are to be
delivered in a name other than the name of the Registered  Holder of the Warrant
Certificate  representing  any Warrant  being  exercised,  then no such delivery
shall be made  unless the  person  requesting  the same has paid to the  Warrant
Agent the amount of transfer taxes or charges incident thereto, if any.

     (d) The Warrant Agent is hereby  irrevocably  authorized to requisition the
Company's Transfer Agent from time to time for certificates  representing shares
of Common Stock  issuable upon  exercise of the  Warrants,  and the Company will
authorize the Transfer  Agent to comply with all such proper  requisitions.  The
Company will file with the Warrant Agent a statement  setting forth the name and
address of the Transfer Agent of the Company for shares of Common Stock issuable
upon exercise of the Warrants. 

     6. EXCHANGE AND REGISTRATION OF TRANSFER.

     (a) Warrant  Certificates  may be exchanged for other Warrant  Certificates
representing an equal  aggregate  number of Warrants of the same class or may be
transferred in whole or in part.  Warrant  Certificates to be exchanged shall be
surrendered to the Warrant Agent at its Corporate Office,  and upon satisfaction
of the terms and  provisions  hereof,  the Company shall execute and the Warrant
Agent shall  countersign,  issue,  and deliver in exchange  therefor the Warrant
Certificate  or  Certificates  which the  Registered  Holder making the exchange
shall be entitled to receive.

     (b) The Warrant  Agent shall keep at its office books in which,  subject to
such  reasonable  regulations  as it may prescribe,  it shall  register  Warrant
Certificates and the transfer  thereof in accordance with its regular  practice.
Upon due presentment for registration of transfer of any Warrant  Certificate at
such office,  the Company  shall  execute and the Warrant  Agent shall issue and
deliver  to  the  transferee  or  transferees  a  new  Warrant   Certificate  or
Certificates  representing  an equal  aggregate  number  of  Warrants.  

     (c) With respect to all Warrant Certificates  presented for registration or
transfer,  or for exchange or  exercise,  the  subscription  form on the reverse
thereof shall be duly endorsed,  or be  accompanied  by a written  instrument or
instruments of transfer and  subscription,  in form  satisfactory to the Company
and  the  Warrant  Agent,   duly  executed  by  the  Registered  Holder  or  his
attorney-in-fact duly authorized in writing.

     (d) A service charge may be imposed on the Registered Holder by the Warrant
Agent for any exchange or registration of transfer of Warrant  Certificates.  In
addition,  the Company may require payment by such holder of a sum sufficient to
cover any tax or other  governmental  charge  that may be imposed in  connection
therewith.

     (e) All Warrant  Certificates  surrendered  for exercise or for exchange in
case of mutilated Warrant Certificates shall be promptly canceled by the Warrant
Agent and  thereafter  retained by the Warrant Agent until  termination  of this
Agreement or resignation as Warrant Agent,  or disposed of or destroyed,  at the
direction of the Company.

     (f) Prior to due presentment  for  registration  of transfer  thereof,  the
Company and the Warrant  Agent may deem and treat the  Registered  Holder of any
Warrant   Certificate  as  the  absolute  owner  thereof  and  of  each  Warrant
represented  thereby  (notwithstanding  any  notations  of  ownership or writing
thereon  made by anyone other than a duly  authorized  officer of the Company or
the Warrant  Agent) for all  purposes and shall not be affected by any notice to
the contrary. The Warrants which are being publicly offered in Units with shares
of Common Stock pursuant to the  Underwriting  Agreement will be detachable from
the Common Stock and transferable  separately  therefrom upon the earlier of (i)
three  (3)  months  from  the  Effective  Date  (as  defined  in  the  Company's
Registration  Statement on Form SB-2 No. 333-3184) or upon agreement between the
Company and Patterson.  




     7. LOSS OR MUTILATION.

     Upon receipt by the Company and the Warrant Agent of evidence  satisfactory
to them of the ownership of and loss, theft,  destruction,  or mutilation of any
Warrant  Certificate  and (in case of loss,  theft, or destruction) of indemnity
satisfactory  to  them,  and (in the  case of  mutilation)  upon  surrender  and
cancellation  thereof, the Company shall execute and the Warrant Agent shall (in
the  absence of notice to the  Company  and/or  Warrant  Agent that the  Warrant
Certificate has been acquired by a bona fide purchaser)  countersign and deliver
to the Registered Holder in lieu thereof a new Warrant Certificate of like tenor
representing an equal aggregate number of Warrants.  Applicants for a substitute
Warrant Certificate shall comply with such other reasonable  regulations and pay
such other reasonable charges as the Warrant Agent may prescribe.

     8. REDEMPTION.

     (a) Subject to the  provisions of paragraph  2(e) hereof,  on not less than
thirty (30) days notice  given at any time after the  Initial  Warrant  Exercise
Date, the Warrants may be redeemed, at the option of the Company at a redemption
price of $0.01 per Warrant,  provided that the Market Price  (defined  below) of
the Common Stock  receivable upon exercise of the Class A Warrant shall equal or
exceed  $13.00  (the  "Target  Price"),  subject to  adjustment  as set forth in
Section  8(f) below.  Market  Price for the purpose of this Section 8 shall mean
(i) the average  closing  bid price for any ten (10)  consecutive  trading  days
within a period of thirty (30)  consecutive  trading days ending within five (5)
days prior to the date of the notice of redemption  which notice shall be mailed
no later than five days  thereafter,  of the  Common  Stock as  reported  by the
National  Association of Securities Dealers,  Inc. Automatic Quotation System or
the NASD Electronic Bulletin Board or (ii) the average of the last reported sale
price,  for ten (10) consecutive  business days,  ending within five (5) days of
the date of the notice of redemption, which notice shall be mailed no later than
five days  thereafter,  on the  primary  exchange  on which the Common  Stock is
traded, if the Common Stock is traded on a national securities exchange.

     (b) If the  conditions  set forth in Section  8(a) are met, and the Company
desires to exercise  its right to redeem the Class A  Warrants,  it shall mail a
notice of  redemption  to each of the  Registered  Holders of the Warrants to be
redeemed,  first class, postage prepaid, not later than the thirtieth day before
the date  fixed for  redemption,  at their last  address as shall  appear on the
records  maintained  pursuant to Section 6 (b). Any notice  mailed in the manner
provided herein shall be  conclusively  presumed to have been duly given whether
or not the Registered Holder receives such notice.  

     (c) The notice of redemption shall specify (i) the redemption  price,  (ii)
the date fixed for  redemption,  (iii) the place where the Warrant  Certificates
shall be delivered  and the  redemption  price paid,  and (iv) that the right to
exercise the Warrant shall terminate at 5:00 P.M. (New York time)on the business
day immediately preceding the date fixed for redemption.  The date fixed for the
redemption  of the Class A Warrant shall be the  Redemption  Date. No failure to
mail such notice nor any defect  therein or in the mailing  thereof shall affect
the validity of the proceedings  for such  redemption  except as to a Registered
Holder (a) to whom notice was not mailed or (b) whose notice was  defective.  An
affidavit of the Warrant Agent or of the Secretary or an Assistant  Secretary of
the Company that notice of redemption  has been mailed shall,  in the absence of
fraud,  be prima facie  evidence of the facts stated  therein.  




     (d) Any right to exercise a Warrant shall  terminate at 5:00 P.M. (New York
time) on the business day  immediately  preceding  the  Redemption  Date. On and
after the Redemption Date,  Holders of the Warrants shall have no further rights
except to receive,  upon surrender of the Warrant prior to the Redemption  Date,
the Redemption  Price. 

     (e) From and after the Redemption Date specified for, the Company shall, at
the place specified in the notice of redemption, upon presentation and surrender
to the Company by or on behalf of the  Registered  Holder thereof of one or more
Warrant Certificates evidencing Warrants to be redeemed,  deliver or cause to be
delivered to or upon the written order of such Holder a sum in cash equal to the
redemption  price of each such Warrant.  From and after the Redemption  Date and
upon the deposit or setting  aside by the Company of a sum  sufficient to redeem
all the Warrants  called for  redemption,  such Warrants shall expire and become
void and all rights  hereunder  and under the Warrant  Certificates,  except the
right to receive payment of the redemption price, shall cease. 

     (f) If the shares of the Company's  Common Stock are subdivided or combined
into a greater or smaller  number of shares of Common  Stock,  the Target  Price
shall be  proportionally  adjusted by the ratio which the total number of shares
of Common Stock  outstanding  immediately prior to such event bears to the total
number of shares of Common Stock to be outstanding immediately after such event.

     9. COMMON  STOCK OR  WARRANTS  ADJUSTMENT  OF EXERCISE  PRICE AND NUMBER OF
SHARES OF COMMON STOCK OR WARRANTS.

     (a) Subject to the  exceptions  referred to in Section  9(g) below,  in the
event the Company shall, at any time or from time to time after the date hereof,
sell any  shares of Common  Stock for a  consideration  per share  less than the
Market Price of the Common Stock (as defined in Section 8) (calculated as of the
date  prior to the date of the  sale) or issue any  shares of Common  Stock as a
stock  dividend  to the holders of Common  Stock,  or  subdivide  or combine the
outstanding  shares of Common  Stock into a greater  or lesser  number of shares
(any such sale,  issuance,  subdivision,  or  combination  being herein called a
"Change of Shares"),  then, and  thereafter  upon each further Change of Shares,
the Purchase Price in effect immediately prior to such Change of Shares shall be
changed to a price  (including any applicable  fraction of a cent) determined by
multiplying  the  Purchase  Price  in  effect  immediately  prior  thereto  by a
fraction,  the  numerator  of which  shall be the sum of the number of shares of
Common  Stock  outstanding  immediately  prior to the  Change of Shares  and the
number of shares of Common  Stock  which the  aggregate  consideration  received
(determined  as provided  in  subsection  9(f)  below) for the  issuance of such
additional  shares  would  purchase at such  current  market  price per share of
Common  Stock,  and the  denominator  of which  shall be the number of shares of
Common Stock outstanding immediately after the Change of Shares. Such adjustment
shall be made successively whenever such an issuance is made.

     Upon each  adjustment of the Purchase Price pursuant to this Section 9, the
total  number of shares of Common  Stock  purchasable  upon the exercise of each
Warrant shall  (subject to the  provisions  contained in Section 9(b) hereof) be
such number of shares  (calculated  to the  nearest  tenth)  purchasable  at the
Purchase Price in effect  immediately  prior to such adjustment  multiplied by a
fraction,  the  numerator  of  which  shall  be the  Purchase  Price  in  effect
immediately  prior to such  adjustment and the denominator of which shall be the
Purchase Price in effect immediately after such adjustment.




     (b) The  Company  may elect,  upon any  adjustment  of the  Purchase  Price
hereunder,  to  adjust  the  number  of  Warrants  outstanding,  in  lieu of the
adjustment in the number of shares of Common Stock purchasable upon the exercise
of each Warrant as hereinabove  provided, so that each Warrant outstanding after
such adjustment shall represent the right to purchase one share of Common Stock.
Each Warrant held of record prior to such  adjustment  of the number of Warrants
shall  become  that  number  of  Warrants  (calculated  to  the  nearest  tenth)
determined by multiplying  the number one by a fraction,  the numerator of which
shall be the Purchase Price in effect  immediately  prior to such adjustment and
the denominator of which shall be the Purchase Price in effect immediately after
such adjustment. Upon each adjustment of the number of Warrants pursuant to this
Section  9,  the  Company  shall,  as  promptly  as  practicable,  cause  to  be
distributed to each  Registered  Holder of Warrant  Certificates  on the date of
such adjustment Warrant Certificates  evidencing,  subject to Section 10 hereof,
the number of  additional  Warrants to which such Holder  shall be entitled as a
result  of such  adjustment  or,  at the  option  of the  Company,  cause  to be
distributed  to such  Holder in  substitution  and  replacement  for the Warrant
Certificates  held by him prior to the date of  adjustment  (and upon  surrender
thereof,  if required by the Company) new Warrant  Certificates  evidencing  the
number of Warrants to which such Holder shall be entitled after such adjustment.

     (c)  After  the  date  hereof,  in  case of any  reclassification,  capital
reorganization,  or other change of  outstanding  shares of Common Stock,  or in
case of any  consolidation  or  merger  of the  Company  with  or  into  another
corporation  (other than a  consolidation  or merger in which the Company is the
continuing  corporation  and  which  does not  result  in any  reclassification,
capital reorganization,  or other change of outstanding shares of Common Stock),
(or in  case  of  any  sale  or  conveyance  to  another  corporation  of all or
substantially  all of the assets of the Company  (other  than a  sale/leaseback,
mortgage,  or other financing  transaction)),  the Company shall cause effective
provision  to be made so that each holder of a Warrant  then  outstanding  shall
have the right thereafter,  by exercising such Warrant, to purchase the kind and
number of shares  of stock or other  securities  or  property  (including  cash)
receivable upon such reclassification,  capital reorganization, or other change,
consolidation,  merger,  sale, or conveyance by a holder of the number of shares
of Common  Stock that might have been  purchased  upon  exercise of such Warrant
immediately prior to such  reclassification,  capital  reorganization,  or other
change,  consolidation,  merger,  sale, or conveyance.  Any such provision shall
include  provision for adjustments that shall be as nearly  equivalent as may be
practicable to the adjustments provided for in this Section 9. The Company shall
not  effect  any  such  consolidation,  merger,  or  sale  unless  prior  to  or
simultaneously with the consummation  thereof,  the successor (if other than the
Company)  resulting  from  such  consolidation  or  merger  or  the  corporation
purchasing  assets or other  appropriate  corporation or entity shall assume, by
written  instrument  executed and delivered to the Warrant Agent, the obligation
to deliver to the holder of each  Warrant such shares of stock,  securities,  or
assets as, in  accordance  with the  foregoing  provisions,  such holders may be
entitled  to  purchase  and the other  obligations  under  this  Agreement.  The
foregoing  provisions  shall  similarly  apply to  successive  reclassification,
capital reorganizations, and other changes of outstanding shares of Common Stock
and  to  successive   consolidations,   mergers,  sales,  or  conveyances.   




     (d) Irrespective of any adjustments or changes in the Purchase Price or the
number of shares of Common Stock purchasable upon exercise of the Warrants,  the
Warrant Certificates theretofore and thereafter issued shall, unless the Company
shall exercise its option to issue new Warrant Certificates  pursuant to Section
2(d)  hereof,  continue to express the Purchase  Price per share,  the number of
shares purchasable thereunder, and the Redemption Price therefor as the Purchase
Price per share,  and the number of shares  purchasable and the Redemption Price
therefore  were  expressed  in the  Warrant  Certificates  when  the  same  were
originally  issued.  

     (e) After each adjustment of the Purchase Price pursuant to this Section 9,
the  Company  will  promptly  prepare a  certificate  signed by the  Chairman or
President, and by the Treasurer or an Assistant Treasurer or the Secretary or an
Assistant Secretary,  of the Company setting forth: (i) the purchase Price as so
adjusted, (ii) the number of shares of Common Stock purchasable upon exercise of
each Warrant  after such  adjustment,  and, if the Company shall have elected to
adjust the number of  Warrants,  the number of Warrants to which the  registered
holder of each Warrant shall then be entitled,  and the adjustment in Redemption
Price resulting  therefrom,  and (iii) a brief statement of the facts accounting
for such  adjustment.  The Company will promptly file such  certificate with the
Warrant  Agent and cause a brief  summary  thereof to be sent by ordinary  first
class mail to Patterson  and to each  registered  holder of Warrants at his last
address  as it shall  appear on the  registry  books of the  Warrant  Agent.  No
failure to mail such  notice nor any defect  therein or in the  mailing  thereof
shall  affect the validity  thereof  except as to the holder to whom the Company
failed  to mail  such  notice,  or  except as to the  holder  whose  notice  was
defective  and who is  prejudiced  thereby.  The  affidavit of an officer of the
Warrant  Agent or the  Secretary or an  Assistant  Secretary of the Company that
such  notice has been  mailed  shall,  in the  absence of fraud,  be prima facie
evidence of the facts stated therein.  

     (f) For purposes of Section 9(a) and 9(b) hereof, the following  provisions
(i) to (vii) shall also be applicable:  

          (i) The number of shares of Common Stock outstanding at any given time
shall include  shares of Common Stock owned or held by or for the account of the
Company and the sale or issuance of such treasury shares or the  distribution of
any such treasury shares shall not be considered a Change of Shares for purposes
of said sections.

          (ii)  No  adjustment  of the  Purchase  Price  shall  be  made  unless
such  adjustment  would require an increase or decrease of at least $.l0 in such
price; provided that any adjustments which by reason of this subsection (ii) are
not  required to be made shall be carried  forward and shall be made at the time
of and together with the next  subsequent  adjustment  which,  together with any
adjustment(s)  so carried  forward,  shall require an increase or decrease of at
least $.10 in the Purchase Price then in effect hereunder.  




          (iii) After the date hereof,  in case of (1)  the sale by the  Company
for cash of any rights or warrants to subscribe for or purchase,  or any options
for the purchase of, either Common Stock or any securities  convertible  into or
exchangeable  for Common Stock without the payment of any further  consideration
other than cash if any (such convertible or exchangeable securities being herein
called "Convertible  Securities"),  or (2) the issuance by the Company,  without
the  receipt by the  Company  of any  consideration  therefor,  of any rights or
warrants to  subscribe  for or  purchase,  or any options for the  purchase  of,
either Common Stock or  Convertible  Securities,  in each case, if (and only if)
the  consideration  payable to the Company  upon the  exercise  of such  rights,
warrants,  or  options  shall  consist  of cash,  whether  or not  such  rights,
warrants,  or options,  or the right.  to convert or exchange  such  Convertible
Securities,  are  immediately  exercisable,  and the  price  per share for which
Common Stock is issuable upon the exercise of such rights,  warrants, or options
or upon the conversion or exchange of such Convertible Securities (determined by
dividing (x) the minimum aggregate consideration payable to the Company upon the
exercise of such rights,  warrants, or options, plus the consideration  received
by the Company for the  issuance or sale of such rights,  warrants,  or options,
plus, in the case of such Convertible  Securities,  the minimum aggregate amount
of additional  consideration,  if any, other than such  Convertible  Securities,
payable upon the conversion or exchange thereof, by (y) the total maximum number
of shares of Common Stock  issuable upon the exercise of such rights,  warrants,
or options or upon the  conversion  or exchange of such  Convertible  Securities
issuable  upon the exercise of such rights,  warrants,  or options) is less than
the  Market  Price  of the  Common  Stock on the  date of the  issuance  or sale
(calculated  as of the date prior to the date of sale)of such rights,  warrants,
or options,  then the total  maximum  number of shares of Common Stock  issuable
upon the exercise of such rights, warrants, or options or upon the conversion or
exchange of such Convertible  Securities (as of the date of the issuance or sale
of such rights,  warrants,  or Options) shall be deemed to be outstanding shares
of Common  Stock for  purposes  of  Sections  9(a) and 9(b)  hereof and shall be
deemed to have been sold for cash in an amount  equal to such  price per  share.

          (iv) In case  of  the  sale by the Company for cash of any convertible
securities,  whether or not the right of  conversion  or exchange  thereunder is
immediately  exercisable,  and the price per  share  for which  Common  Stock is
issuable  upon  the  conversion  or  exchange  of  such  Convertible  Securities
(determined  by dividing (x) the total amount of  consideration  received by the
Company for the sale of such Convertible Securities,  plus the minimum aggregate
amount  of  additional  consideration,  if  any,  other  than  such  Convertible
Securities,  payable upon the conversion or exchange  thereof,  by (y) the total
maximum  number of  shares  of Common  Stock  issuable  upon the  conversion  or
exchange of such Convertible  Securities  determined as of the date of issuance)
is less than the  Market  Price of the  Common  Stock on the date of the sale of
such  Convertible  Securities  (calculated  as of the date  prior to the date of
sale), then the total maximum number of shares of Common Stock issuable upon the
conversion  or exchange of such  Convertible  Securities  (as of the date of the
sale of such Convertible Securities) shall be deemed to be outstanding shares of
Common Stock for  purposes of Sections  9(a) and 9(b) hereof and shall be deemed
to have been sold for cash in an amount  equal to such price per  share.  

          (v) In  case  the  Company  shall  modify  the  rights  of conversion,
exchange,  or exercise of any of the securities  referred to in subsection (iii)
above or any other  securities  of the  Company  convertible,  exchangeable,  or
exercisable for shares of Common Stock,  for any reason other than an event that
would require  adjustment to prevent  dilution,  so that the  consideration  per
share  received by the Company after such  modification  is less than the Market
Price on the date prior to such modification (calculated as of the date prior to
the date of sale),  the Purchase  Price to be in effect after such  modification
shall be  determined by  multiplying  the Purchase  Price in effect  immediately
prior to such event by a fraction, of which the numerator shall be the number of
shares of Common  Stock  outstanding  plus the number of shares of Common  Stock
which the aggregate  consideration  receivable by the Company for the securities
affected by the modification  would purchase at the Market Price  (calculated as
of the date prior to the date of sale)and of which the denominator  shall be the
number of shares of Common  Stock  outstanding  on such date plus the  number of
shares of Common Stock to be issued upon  conversion,  exchange,  or exercise of
the modified  securities  at the modified  rate.  Such  adjustment  shall become
effective as of the date upon which such modification shall take effect. 




          (vi) On the expiration  of any such right,  warrant,  or option or the
termination  of any such  right to  convert  or  exchange  any such  Convertible
Securities,  the  Purchase  Price then in effect  hereunder  shall  forthwith be
readjusted to such purchase Price as would have obtained (a) had the adjustments
made upon the issuance or sale of such rights, warrants, options, or Convertible
Securities been made upon the basis of the issuance of only the number of shares
of Common Stock  theretofore  actually  delivered  (and the total  consideration
received  therefor)  upon the exercise of such rights,  warrants,  or options or
upon the  conversion  or exchange of such  Convertible.  Securities  and (b) had
adjustments  been  made on the basis of the  Purchase  Price as  adjusted  under
clause  (a) for all  transactions  (which  would  have  affected  such  adjusted
Purchase  Price)  made  after the  issuance  or sale of such  rights,  warrants,
options,  or  Convertible  Securities.  

          (vii)  In case of the sale  (other  than pursuant  to the Stock Option
Plan or the  Warrants)for  cash of any shares of Common Stock,  any  Convertible
Securities,  any rights or warrants to subscribe for or purchase, or any options
for the purchase of, Common Stock or Convertible  Securities,  the consideration
received  by the Company  therefore  shall be deemed to be the gross sales price
therefor without deducting therefrom any expense paid or incurred by the Company
or any  underwriting  discounts or commissions or concessions paid or allowed by
the Company in connection therewith.  

     (g) No adjustment to the Purchase Price of the Warrants or to the number of
shares of Common  Stock  purchasable  upon the  exercise of each Warrant will be
made, however,

          (i) upon  the  sale  or  exercise  of the Warrants,  including without
limitation  the  sale  or  exercise  of  any  of  the  Warrants  comprising  the
Underwriter's Options; or

          (ii) upon the  sale  of  any  shares of Common  Stock in the Company's
initial public offering,  including,  without  limitation,  shares sold upon the
exercise of any over-allotment  option granted to the Underwriters in connection
with such  offering;  or 

          (iii)  upon  the  issuance  or  sale  of  Common  Stock or Convertible
Securities  upon the  exercise  of any rights or warrants  to  subscribe  for or
purchase,  or any options  for the  purchase  of,  Common  Stock or  Convertible
Securities, whether or not such rights, warrants, or options were outstanding on
the date of the original sale of the Warrants or were thereafter issued or sold;
or 

          (iv) upon  the  issuance  or  sale  of Common Stock upon conversion or
exchange of any  Convertible  Securities,  whether or not any  adjustment in the
Purchase Price was made or required to be made upon the issuance or sale of such
Convertible  Securities  and  whether or not such  Convertible  Securities  were
outstanding on the date of the original sale of the Warrants or were  thereafter
issued or sold; or 




          (v)  upon  the  issuance  or  sale  of  Common  Stock  or  Convertible
Securities in a private placement unless the issuance or sale price is less than
85% of the fair market  value of the Common  Stock on the date of  issuance,  in
which case the adjustment  shall only be for the  difference  between 85% of the
fair market value and the issue or sale price; 

          (vi) upon  the  issuance  or  sale  of  Common  Stock  or  Convertible
Securities to (a) shareholders of any corporation  which merges into the Company
or from which the Company  acquires assets and some or all of the  consideration
consists of equity  securities  of the  Company,  in  proportion  to their stock
holdings of such corporation  immediately prior to the acquisition or (b) to any
corporation  or person  from which the  Company  acquires  assets but only if no
adjustment  is required  pursuant to any other  provision  of this Section 9; or

          (vii) upon the  issuance or sale of (i) up to 200,000  options for the
purchase Common Stock to employees, officers, directors, advisors or consultants
under the Stock  Option Plan or (ii) Common  Stock  issued upon the  exercise of
options  granted under the Stock Option Plan. 

     (h) As used in this  Section  9, the term  "Common  Stock"  shall  mean and
include the Company's  Common Stock authorized on the date of the original issue
of the  Units and  shall  also  include  any  capital  stock of any class of the
Company  thereafter  authorized  which  shall not be  limited  to a fixed sum or
percentage  in respect of the rights of the holders  thereof to  participate  in
dividends  and in the  distribution  of assets upon the  voluntary  liquidation,
dissolution,  or winding up of the Company;  provided,  however, that the shares
issuable upon  exercise of the Warrants  shall include only shares of such class
designated in the Company's  Certificate of Incorporation as Common Stock on the
date  of  the  original   issue  of  the  Units,   or  (i)in  the  case  of  any
reclassification,  change,  consolidation,  merger,  sale,  or conveyance of the
character referred to in Section 9(c) hereof, the stock, securities, or property
provided  for in such  section or, (ii) in the case of any  reclassification  or
change in the  outstanding  shares of Common Stock issuable upon exercise of the
Warrants as a result of a subdivision  or  combination or consisting of a change
in par  value,  or from par value to no par  value,  or from no par value to par
value, such shares of Common Stock as so reclassified or changed.

     (i) Any  determination as to whether an adjustment in the Purchase Price in
effect  hereunder is required  pursuant to Section 9, or as to the amount of any
such adjustment,  if required, shall be binding upon the holders of the Warrants
and the Company if made in good faith by the Board of  Directors of the Company.

     (j) Intentionally omitted.

     10. FRACTIONAL WARRANTS AND FRACTIONAL SHARES

     (a) If the number of shares of Common Stock  purchasable  upon the exercise
of  each  Warrant  is  adjusted  pursuant  to  Section  9  hereof,  the  Company
nevertheless  shall not be required to issue fractions of shares,  upon exercise
of the  Warrants or  otherwise,  or to  distribute  certificates  that  evidence
fractional  shares.  With respect to any fraction of a share called for upon any
exercise hereof,  the Company shall pay to the Holder an amount in cash equal to
such fraction  multiplied by the current market value of such fractional  share,
determined as follows:




          (i) If  the  Common Stock is listed on a National  Securities Exchange
or  admitted  to  unlisted  trading  privileges  on such  exchange or listed for
trading on the NASDAQ  Quotation  System or the NASD Electronic  Bulletin Board,
the current  value shah be the last  reported  sale price of the Common Stock on
such  exchange  on the last  business  day prior to the date of exercise of this
Warrant or if no such sale is made on such day,  the  average of the closing bid
and asked prices for such day on such exchange; or

          (ii)  If the Common  Stock  is not  listed  or  admitted  to  unlisted
trading privileges, the current value shall be the mean of the last reported bid
and asked prices  reported by the National  Quotation  Bureau,  Inc. or the NASD
Electronic  Bulletin  Board on the last  business  day  prior to the date of the
exercise  of this  Warrant;  or 

          (iii) If the  Common  Stock is not so  listed or admitted  to unlisted
trading  privileges  and bid and asked prices are not so  reported,  the current
value  shall  be an  amount  determined  in  such  reasonable  manner  as may be
prescribed  by the Board of Directors of the Company.

     11. WARRANT HOLDERS NOT DEEMED STOCKHOLDERS No holder of Warrants shall, as
such,  be  entitled to vote or to receive  dividends  or be deemed the holder of
Common Stock that may at any time be issuable upon exercise of such Warrants for
any purpose  whatsoever,  nor shall  anything  contained  herein be construed to
confer upon the holder of Warrants,  as such, any of the rights of a stockholder
of the Company or any right to vote for the  election of  directors  or upon any
matter submitted to stockholders at any meeting thereof,  or to give or withhold
consent to any corporate  action  (whether upon any  recapitalization,  issue or
reclassification  of  stock,  change  of par  value or change of stock to no par
value, consolidation,  merger, or conveyance or otherwise), or to receive notice
of meetings,  or to receive dividends or subscription  rights, until such Holder
shall have  exercised  such  Warrants and been issued  shares of Common Stock in
accordance with the provisions hereof.

     12. RIGHTS OF ACTION.  All rights of action with respect this Agreement are
vested in the  respective  Registered  Holders the Warrants,  and any Registered
Holder of a Warrant,  without  consent of the Warrant  Agent or of the holder of
any other  Warrant,  may,  in his own  behalf and for his own  benefit,  enforce
against  the  Company his right to exercise  his  Warrants  for the  purchase of
shares of Common  Stock in the manner  provided in the Warrant  Certificate  and
this Agreement.  

     13.  AGREEMENT  OF  WARRANT  HOLDERS  Every  holder  of a  Warranty  by his
acceptance thereof,  consents and agrees with the Company, the Warrant Agent and
every other holder of a Warrant that: 

     (a) The Warrants are transferable only on the registry books of the Warrant
Agent by the  Registered  Holder  thereof  in  person  or by his  attorney  duly
authorized  in writing and only if the Warrant  Certificates  representing  such
Warrants are  surrendered at the office of the Warrant  Agent,  duly endorsed or
accompanied by a proper instrument of transfer satisfactory to the Warrant Agent
and  the  Company  in  their  sole  discretion,  together  with  payment  of any
applicable transfer taxes; and




     (b) The  Company  and the  Warrant  Agent may deem and treat the  person in
whose  name the  Warrant  Certificate  is  registered  as the  holder and as the
absolute,  true,  and lawful owner of the Warrants  represented  thereby for all
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice or knowledge to the contrary,  except as otherwise  expressly provided in
Section 7 hereof. 

     14. CANCELLATION OF WARRANT CERTIFICATES.  If the Company shall purchase or
acquire any Warrant or Warrants, the Warrant Certificate or Warrant Certificates
evidencing  the same shall  thereupon  be  delivered  to the  Warrant  Agent and
canceled by it and retired.  The Warrant  Agent shall also cause to be cancelled
Common  Stock  following  exercise  of any or  all of the  Warrants  represented
thereby or delivered to it for transfer, split up, combination, or exchange.

     15. CONCERNING THE WARRANT AGENT. The Warrant Agent acts hereunder as agent
and in a  ministerial  capacity  for  the  Company,  and  its  duties  shall  be
determined  solely by the  provisions  hereof.  The Warrant  Agent shall not, by
issuing and  delivering  Warrant  Certificates  or by any other act hereunder be
deemed to make any  representations as to the validity,  value, or authorization
of the  Warrant  Certificates  or the  Warrants  represented  thereby  or of any
securities  or other  property  delivery upon exercise of any Warrant or whether
any stock issued upon  exercise of any Warrant is fully paid and  nonassessable.

     The Warrant Agent shall not at any time be under any duty or responsibility
to any holder of Warrant Certificates to make or cause to be made any adjustment
of the Purchase Price or the Redemption Price provided in this Agreement,  or to
determine  whether any fact exists  which may require any such  adjustments,  or
with respect to the nature or extent of any such adjustment,  when made, or with
respect to the method  employed  in making the same.  It shall not (i) be liable
for any recital or statement of facts contained  herein or for any action taken,
suffered,  or omitted by it in  reliance  on any  Warrant  Certificate  or other
document  or  instrument  believed by it in good faith to be genuine and to have
been signed or presented by the proper party or parties, (ii) be responsible for
any failure on the part of the Company to comply with any of its  covenants  and
obligations contained in this Agreement or in any Warrant Certificate,  or (iii)
be liable for any act or omission in connection  with this Agreement  except for
its own negligence or willful misconduct.

     The Warrant Agent may at any time consult with counsel  satisfactory  to it
(who  may  be  counsel  for  the  Company)  and  shall  incur  no  liability  or
responsibility for any action taken,  suffered or omitted by it in good faith in
accordance with the opinion or advice of such counsel.

     Any notice, statement, instruction, request, direction, order, or demand of
the Company  shall be  sufficiently  evidenced  by an  instrument  signed by the
Chairman  of the  Board,  President,  any  Vice  President,  its  Secretary,  or
Assistant  Secretary  (unless  other  evidence  in  respect  thereof  is  herein
specifically  prescribed).  The Warrant Agent shall not be liable for any action
taken,  suffered or omitted by it in  accordance  with such  notice,  statement,
instruction, request, direction, order, or demand believed by it to be genuine.




     The Company agrees to pay the Warrant Agent reasonable compensation for its
services hereunder and to reimburse it for its reasonable expenses hereunder; it
further  agrees to indemnify the Warrant Agent and save it harmless  against any
and all losses, expenses, and liabilities,  including judgments, costs, Agent in
the execution of its duties and powers  hereunder except losses,  expenses,  and
liabilities  arising as a result of the Warrant  Agent's  negligence  or willful
misconduct.

     The Warrant Agent may resign its duties and be discharged  from all further
duties and liabilities  hereunder (except liabilities arising as a result of the
Warrant  Agent's own  negligence or willful  misconduct),  after  giving 30 days
prior  written  notice to the  Company.  At least 15 days prior to the date such
resignation is to become effective, the Warrant Agent shall cause a copy of such
notice of  resignation  to be mailed to the  Registered  Holder of each  Warrant
Certificate at the Company's expense. Upon such resignation, or any inability of
the Warrant  Agent to act as such  hereunder,  the Company  shall  appoint a new
warrant  agent in writing.  If the Company  shall fail to make such  appointment
within  a  period  of 15 days  after it has been  notified  in  writing  of such
resignation by the resigning  Warrant Agent,  then the Registered  Holder of any
Warrant  Certificate  may apply to any court of competent  jurisdiction  for the
appointment of a new warrant agent. Any new warrant agent,  whether appointed by
the  Company  or by such a  court,  shall be a bank or  trust  company  having a
capital and surplus,  as shown by its last published report to its stockholders,
of not less than  $10,000,000 or a stock transfer  company.  After acceptance in
writing of such appointment by the new warrant agent is received by the Company,
such new warrant agent shall be vested with the same powers, rights, duties, and
responsibilities as if it had been originally named herein as the Warrant Agent,
without any further assurance,  conveyance,  act, or deed; but if for any reason
it shall be necessary or expedient to execute and deliver any further assurance,
conveyance,  act, or deed,  the same shall be done at the expense of the Company
and shall be legally and validly executed and delivered by the resigning Warrant
Agent.  Not later than the effective  date of any such  appointment  the Company
shall file notice thereof with the resigning  warrant Agent and shall  forthwith
cause a copy of such  notice  to be  mailed  to the  Registered  Holder  of each
Warrant Certificate.

     Any  corporation  into which the Warrant Agent or any new warrant agent may
be converted or merged or any corporation  resulting from any  consolidation  to
which  the  Warrant  Agent  or any new  warrant  agent  shall  be a party or any
corporation  succeeding  to the trust  business of the Warrant  Agent shall be a
successor  warrant agent under this Agreement  without any further act, provided
that such  corporation  is eligible for  appointment as successor to the Warrant
Agent  under the  provisions  of the  preceding  paragraph.  Any such  successor
warrant agent shall  promptly cause notice of its succession as warrant agent to
be  mailed  to  the  Company  and to  the  Registered  Holder  of  each  Warrant
Certificate.

     The Warrant Agent, its subsidiaries and affiliates, and any of its or their
officers or directors,  may buy and hold or sell Warrants or other securities of
the  Company and  otherwise  deal with the Company in the same manner and to the
same extent and with like effects as though it were not Warrant  Agent.  Nothing
herein shall  preclude the Warrant  Agent from acting in any other  capacity for
the Company or for any other legal entity.




     16.  MODIFICATION  OF  AGREEMENT  The Warrant  Agent and the Company may by
supplemental  agreement  make any changes or  corrections  in this Agreement (i)
that they  shall  deem  appropriate  to cure any  ambiguity  or to  correct  any
defective  or  inconsistent  provision  or  manifest  mistake  or  error  herein
contained; or (ii) that they may deem necessary or desirable and which shall not
adversely affect the interests of the holders of Warrant Certificates; PROVIDED.
HOWEVER,  that this Agreement  shall not otherwise be modified,  supplemented or
altered in any  respect  except  with the  consent in writing of the  Registered
Holders of Warrant  Certificates  representing not less than 50% of the Warrants
then outstanding;  and PROVIDED, FURTHER, that no change in the number or nature
of the securities  purchasable upon the exercise of any Warrant, or the Purchase
Price therefor,  or the  acceleration of the Warrant  Expiration  Date, shall be
made  without  the  consent in writing of the  Registered  Holder of the Warrant
Certificate   representing  such  Warrant,   other  than  such  changes  as  are
specifically  prescribed by this Agreement as originally executed or are made in
compliance with  applicable  law. In addition,  the Company and Patterson may by
supplemental agreement extend the Warrant Expiration Date without the consent of
the Registered Holders.

     17. NOTICES.  All notices,  requests,  consents,  and other  communications
hereunder  shall be in  writing  and  shall be  deemed  to have  been  made when

accordance  with  the  laws of the  State  of New  York,  without  reference  to
principles of conflict of laws. 

     19. BINDING  EFFECT.  This Agreement shall be binding upon and inure to the
benefit of the Company and, the Warrant  Agent and their  respective  successors
and assigns, and the holders from time to time of Warrant Certificates.  Nothing
in this  Agreement  is intended or shall be  construed  to confer upon any other
person any right,  remedy,  or claim, in equity or at law, or to impose upon any
other person any duty, liability, or obligation. 

     20. TERMINATION. This Agreement shall terminate at the close of business on
the Warrant  Expiration Date of all the Warrants or such earlier date upon which
all Warrants have been exercised, except that the Warrant Agent shall account to
the Company for cash held by it and the  provisions  of Section 15 hereof  shall
survive such termination.  

     21. COUNTERPARTS.  This Agreement may be executed in several  counterparts,
which taken together shall constitute a single document.

                                   MEDJET INC.


                     THIS CERTIFIES THAT FOR VALUE RECEIVED

or registered  assigns (the  "Registered  Holder") is the owner of the number of
Class A Redeemable Common Stock Purchase Warrants ("Warrants")  specified above.
Each Warrant initially  entitles the Registered  Holder to purchase,  subject to
the terms and conditions set forth in this Certificate and the Warrant Agreement
(as  hereinafter  defined),  one fully  paid and  nonassessable  share of Common
Stock, $.001 par value ("Common Stock"), of MEDJET INC., a Delaware  corporation
(the  "Company"),  at any time  between the Initial  Warrant  Exercise  Date (as
herein  defined) and the  Expiration  Date (as  hereinafter  defined),  upon the
presentation  and surrender of this Warrant  Certificate  with the  Subscription
Form on the reverse hereof duly executed, at the Corporate office of Continental
STOCK TRANSFER & TRUST COMPANY, as Warrant Agent, or its successor (the "Warrant
Agent"),  accompanied by payment of $10.00 ("Purchase Price") in lawful money of
the United States of America in cash or by official bank or certified check made
payable to  Continental  Stock  Transfer & Trust  Company,  as Warrant Agent for
MEDJET INC.

      This Warrant  Certificate and each Warrant  represented  hereby are issued
pursuant to and are  subject in all  respects  to the terms and  Conditions  set
forth in the Warrant  Agreement (the "Warrant  Agreement") dated August 6, 1996,
by and between the Company and the Warrant Agent.

      In the  event  of  certain  Contingencies  provided  for  in  the  Warrant
Agreement, the Purchase Price or the number of shares of Common Stock subject to
purchase  upon the  exercise of each Warrant  represented  hereby are subject to
modifications or adjustment.

      Each  Warrant  represented  hereby  is  exercisable  at the  option of the
Registered  Holder,  but no fractional shares of Common Stock will be issued. In
the case of the exercise of less than all the Warrants  represented  hereby, the
Company  shall cancel this Warrant  Certificate  upon the  surrender  hereof and
shall execute and deliver a new Warrant  Certificate or Warrant  Certificates of
like tenor, which the Warrant Agent shall  countersign,  for the balance of such
Warrants.




      The term "Initial Warrant Exercise Date" shall mean November 6, 1996.

      The term "Expiration Date" shall mean 5:00 p.m. (New York time on November

a day on which banks are authorized to close.

the  exercise  of  this  Warrant  unless  a  registration  statement  under  the
Securities  Act of  1933,  as  amended,  with  respect  to  such  securities  is
effective.   The  Company  has  covenanted  and  agreed  that  it  will  file  a
registration statement and will use its best efforts to cause the same to become
effective  and to keep  such  registration  statement  current  while any of the
Warrants are outstanding.  This Warrant shall not be exercisable by a Registered
Holder in any state where such exercise would be unlawful.

      This Warrant Certificate is exchangeable, upon the surrender hereof by the
Registered  Holder at the  corporate  office  of the  Warrant  Agent,  for a new
Warrant Certificate or Warrant  Certificates of like tenor representing an equal
aggregate number of Warrants, each of such new Warrant Certificates to represent
such number of Warrants as shall be designated by such Registered  Holder at the
time of such surrender.  Upon due presentment  with any transfer fee in addition
to any tax or other  governmental  charge imposed in Connection  therewith,  for
registration  of transfer of this  Warrant  Certificate  at such  office,  a new
Warrant  Certificate or Warrant  Certificates  representing  an equal  aggregate
number of  Warrants  will be  issued to the  transferee  in  exchange  therefor,
subject to the limitations provided in the Warrant Agreement.

      Prior to the exercise of any Warrant  represented  hereby,  the Registered
Holder  shall not be entitled  to any rights of a  Stockholder  of the  Company,
including,  without  limitation,  the right to vote or to receive  dividends  or
other  distributions,  and shall not be  entitled  to receive  any notice of any
proceedings of the Company, except as provided in the Warrant Agreement.

      This Warrant may be redeemed at the option of the Company, at a redemption
price of $.0l per Warrant at any time after the Initial  Warrant  Exercise  Date
(as defined in the Warrant Agreement),  provided the Market Price (as defined in
the Warrant Agreement) for the securities issuable upon exercise of such Warrant
shall exceed  $13.00 per share.  Notice of  redemption  shall be given not later
than the thirtieth day before the date fixed for redemption,  all as provided in
the  Warrant  Agreement.  On and  after  the  date  fixed  for  redemption,  the
Registered  Holder shall have no rights with  respect to this Warrant  except to
receive the $.0l per Warrant  upon  surrender of this  Certificate  prior to the
Redemption Date (as defined in the Warrant Agreement).

      Prior to due presentment for registration of transfer hereof,  the Company
and the Warrant Agent may deem and treat the  Registered  Holder as the absolute
owner  hereof  and of  each  Warrant  represented  hereby  (notwithstanding  any
notations  of  ownership  or  writing  hereon  made by anyone  other than a duly
authorized  officer of the Company or the Warrant  Agent) for all  purposes  and
shall not be affected by any notice to the contrary.

with the laws of the State of Delaware.

Agent.
