not offer for sale or sell more than an  aggregate  of 25% of the  Shares.  This
Warrant and the right to purchase Shares  hereunder shall expire and become void
at the Expiration Date.

               2.2    Manner of Exercise.

                      (a) Holder may exercise  this Warrant at any time and from
time to time  during  the  Exercise  Period,  in  whole  or in part  (but not in
denominations  of fewer than  25,000  shares,  except  upon an  exercise of this
Warrant with respect to the remaining balance of shares purchasable hereunder at
the time of exercise),  by delivering to the Company at its Corporate Office (i)
a duly  executed  Notice of  Exercise  in  substantially  the form  attached  as
Appendix 1 hereto,  (ii) a check for the aggregate  Exercise Price of the shares
of Common Stock being purchased, and (iii) a written opinion of counsel, in form
and substance  satisfactory  to the Company,  to the effect that the Warrant and
the Shares  delivered  upon  exercise  hereof,  have been  registered  under the
Securities Act of 1933, as amended, or are exempt from registration thereunder.

                      (b) From time to time,  until the  Expiration  Date,  upon
exercise of this Warrant,  in whole or part, in accordance  with its terms,  the
Transfer Agent will  countersign  and deliver stock  certificates  to the Holder
representing  the number of Shares being  purchased  pursuant to such  exercise,
subject to adjustment as described herein.

                      (c) Promptly  following any exercise of this  Warrant,  if

other rights as holder of shares of Common Stock.


                                       2




               2.5 Anti-dilution  Adjustments.  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 or Common Stock),
or in case of any sale or conveyance to another  corporation  of the property of
the Company as, or substantially  as, an entirety (other than a  sale/leaseback,
mortgage or other  financing  transaction),  the Company  shall cause  effective
provision  to be made so that the  Holder  shall have the right  thereafter,  by
exercising  this 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 (or other
appropriate  securities)  which  would  have been  issued to the  Holder had the
Holder exercised the Warrant immediately before 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
2.5.   The   foregoing   provisions   shall   similarly   apply  to   successive
reclassifications,  capital  reorganizations  and other  changes of  outstanding
shares  of Common  Stock and to  successive  consolidations,  mergers,  sales or
conveyances.

               2.6  Fractional  Shares.  No fractional  Shares shall be issuable
upon  exercise  or  conversion  of this  Warrant  and the number of Shares to be
issued shall be rounded down to the nearest whole Share.  If a fractional  share
interest  arises upon any exercise or  conversion  of the  Warrant,  the Company
shall  eliminate  such  fractional  share  interest by paying  Holder the amount
computed by multiplying  the  fractional  interest by the closing bid price of a
full share of the Company's Common Stock on the date of the Notice of Exercise.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

               3.1 Representations and Warranties. The Company hereby represents
and warrants to the Holder as follows:

                      (a) All Shares  which may be issued  upon the  exercise of
the purchase right  represented by this Warrant  shall,  upon issuance,  be duly
authorized, validly issued, fully-paid and nonassessable,  and free of any liens
and  encumbrances  except for  restrictions  on transfer  provided for herein or
under  applicable  federal  and state  securities  laws,  and not subject to any
pre-emptive rights.


                                       3






                      (b)  The  Company  is a  corporation  duly  organized  and
validly existing under the laws of the state of Delaware, and has the full power
and  authority  to issue this Warrant and to comply with the terms  hereof.  The
execution, delivery and performance by the Company of its obligations under this
Warrant,  including,  without  limitation,  the  issuance of the Shares upon any
exercise of the Warrant have been duly  authorized  by all  necessary  corporate
action.  This Warrant has been duly executed and delivered by the Company and is
a valid and binding  obligation of the Company,  enforceable in accordance  with
its  terms,  except as  enforcement  may be limited  by  applicable  bankruptcy,
insolvency,   reorganization   or  similar  laws  affecting   enforceability  of
creditors'  rights  generally  and except as the  availability  of the remedy of
specific enforcement,  injunctive relief or other equitable relief is subject to
the discretion of the court before which any proceeding therefor may be brought.

                      (c)  The  Company  is  not  subject  to or  bound  by  any
provision of any certificate or articles of incorporation or by-laws,  mortgage,
deed of trust,  lease,  note,  bond,  indenture,  other instrument or agreement,
license,  permit,  trust,  custodianship,  other  restriction  or any applicable
provision  of  any  law,  statute,  rule,  regulation,  judgment,  order,  writ,
injunction or decree of any court,  governmental body,  administrative agency or
arbitrator which could prevent or be violated by or under which there would be a
default (or right of  termination)  as a result of the  execution,  delivery and
performance by the Company of this Warrant.

ARTICLE 4. REGISTRATION UNDER THE ACT.

                      (a) On or  before  August 1,  1996,  the  Company  agrees,
subject to applicable  law, to file with the Securities and Exchange  Commission
(the "SEC") a registration on form S-8 so as to permit the public offer and sale
of the Shares.  The Company will not be required to take any action with respect
to or make any  filing  under  state  "Blue sky"  laws.  If an S-8  registration
statement  shall be unavailable  to the Company with respect to the Shares,  the
Company shall,  upon receipt a written request  therefore (the "Demand Request")
given on or after  December  28, 1996,  from any record  holder or holders of an
aggregate of more than 50% of this Warrant,  then, the Company shall prepare and
file with the SEC a registration  statement  under the Act covering this Warrant
(or any warrant or warrants issued in substitution or exchange therefor) and the
Common Stock  issuable upon exercise of this Warrant (or any warrant or warrants
issued in substitution or exchange  therefor)  (collectively,  the  "Registrable
Securities")  which  are the  subject  of such  request  and  shall use its best
efforts to cause such registration  statement to become effective.  In addition,
upon the receipt of such request, the Company shall promptly give written notice
to all other record holders of the Registrable Securities that such registration
is to be effected. The Company shall include in such registration statement such



                                       4






Registrable Securities for which it has received written requests to register by
such other  record  holders  within  thirty (30) days after the  delivery of the
Company's  written notice to such other record holders.  All record holders from
whom the Company shall have received requests to register Registrable Securities
as provided herein are hereinafter referred to as the "Requesting Holders."

                      If at the time of the Demand  Notice the Company is in the
process of  preparing  a  registration  statement  under the Act  relating to an
underwritten  public  offering,  then no holder of  securities  of the  Company,
including  Requesting  Holders may include securities in such registration if in
the good faith judgment of the managing  underwriter of such public offering the
inclusion of such securities  would  interfere with the successful  marketing of
the  securities   being   underwritten.   Securities  to  be  excluded  from  an
underwritten public offering shall be selected in a manner provided in paragraph
(b) below. To the extent only a portion of the Registrable  Securities held by a
Requesting   Holder  is  included  in  the  underwritten   public  offering,   a
registration  statement covering those Registrable Securities which are excluded
from the  underwritten  public  offering  will be filed  within  120 days of the
consummation of the underwritten public offering.

                      The  obligation  of the Company  under this  paragraph (a)
shall be  limited  to one  registration  statement.  The  Company  shall pay the
expenses  described in paragraph (c) below for the registration  statement filed
pursuant  to  this  paragraph  (a),  except  for   underwriting   discounts  and
commissions  and legal fees of the Requesting  Holders,  which shall be borne by
the Requesting Holders.

                      (b)  The  number  of  shares  of  Registerable  Securities
otherwise to be included in an  underwritten  public  offering  (the  "Requested
Stock") may be reduced pro rata (by number of shares) among the holders  thereof
requesting such registration or excluded in their entirety if so required by the
underwriter  as provided  herein.  To the extent only a portion of the Requested
Stock is included in the underwritten public offering, those shares of Requested
Stock which are thus excluded from the  underwritten  public  offering  shall be
withheld from the market by the holders thereof for a period,  not to exceed 120
days, which the managing underwriter reasonably determines is necessary in order
to effect the underwritten public offering.

                      (c) Registration  Procedures.  If and whenever the Company
is required by the provisions of paragraph (a) above to effect the  registration
of Registrable Securities under the Act, the Company will:

                             (i)  prepare  and file with the SEC a  registration
statement  with  respect to such  securities,  and use its best efforts to cause
such  registration  statement to become and 



                                       5






remain  effective for such period as may be  reasonably  necessary to effect the
sale of such securities, not to exceed two years;

                             (ii) prepare and file with the SEC such  amendments
to such  registration  statement and  supplements  to the  prospectus  contained
therein as may be necessary to keep such  registration  statement  effective for
such  period  as  may be  reasonably  necessary  to  effect  the  sale  of  such
securities, not to exceed two years months;

                             (iii) furnish to the security holders participating
in such  registration and to the underwriters of the securities being registered
such  reasonable  number of copies of the  registration  statement,  preliminary
prospectus,  final prospectus and such other documents as such  underwriters may
reasonably   request  in  order  to  facilitate  the  public  offering  of  such
securities;

                             (iv) notify the security  holders  participating in
such registration,  promptly after it shall receive notice thereof,  of the time
when such  registration  statement  has become  effective or a supplement to any
prospectus forming a part of such registration statement has been filed;

                             (v) notify such holders  promptly of any request by
the SEC for the  amending or  supplementing  of such  registration  statement or
prospectus or for additional information;

                             (vi) prepare and file with the SEC,  promptly  upon
the  request  of any  such  holders,  any  amendments  or  supplements  to  such
registration  statement or prospectus  which, in the opinion of counsel for such
holders (and concurred in by counsel for the Company), is required under the Act
or the rules and regulations  thereunder in connection with the  distribution of
Common Stock by such holder;

                             (vii)  prepare and  promptly  file with the SEC and
promptly  notify such holders of the filing of such  amendment or  supplement to
such  registration  statement or  prospectus  as may be necessary to correct any
statements  or  omissions  if, at the time when a  prospectus  relating  to such
securities  is  required  to be  delivered  under the Act,  any event shall have
occurred as the result of which any such  prospectus or any other  prospectus as
then in effect would  include an untrue  statement of a material fact or omit to
state any material fact necessary to make the statements  therein,  in the light
of the circumstances in which they were made, not misleading; and

                             (viii) advise such holders, promptly after it shall
receive notice or obtain knowledge thereof, of the issuance of any stop order by
the SEC  suspending  the  effectiveness  of such  registration  statement or the
initiation or  threatening  of 



                                       6






any proceeding for that purpose and promptly use its best efforts to prevent the
issuance of any stop order or to obtain its withdrawal if such stop order should
be issued.

                      (d) Expenses.

                             (i) With  respect  to each  registration  requested
pursuant to paragraph (a) above,  all fees, costs and expenses of and incidental
to such  registration,  inclusion and public offering (as specified in paragraph
(ii) below) in  connection  therewith  shall be borne by the Company,  provided,
however, that any security holders participating in such registration shall bear
their pro rata share of the  underwriting  discount and commissions and transfer
taxes.

                             (ii) The fees,  costs and expenses of  registration
to be borne by the  Company as provided in  paragraph  (i) above shall  include,
without limitation, all registration,  filing, and NASD fees, printing expenses,
fees and  disbursements  of counsel and  accountants  for the Company.  Fees and
disbursements  of counsel and accountants for the selling  security  holders and
any other  expenses  incurred by the  selling  security  holders  not  expressly
included above shall be borne by the selling security holders.

                      (e) Indemnification.

                             (i) The Company will  indemnify  and hold  harmless
each holder of  Registrable  Securities  which are  included  in a  registration
statement  pursuant to the provisions of paragraph (a) above,  its directors and
officers,  and any  underwriter (as defined in the Act) for such holder and each
person, if any, who controls such holder or such underwriter  within the meaning
of the Act,  from and  against,  and will  reimburse  such  holder and each such
underwriter  and controlling  person with respect to, any and all loss,  damage,
liability,  cost and  expense to which such  holder or any such  underwriter  or
controlling  person may become  subject under the Act or  otherwise,  insofar as
such losses,  damages,  liabilities,  costs or expenses are caused by any untrue
statement or alleged  untrue  statement of any material  fact  contained in such
registration  statement,  any prospectus  contained  therein or any amendment or
supplement  thereto,  or arise out of or are based upon the  omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading;  provided, however, that the Company will not be
liable in any such case to the  extent  that any such loss,  damage,  liability,
cost or expenses  arises out of or is based upon an untrue  statement or alleged
untrue  statement  or omission or alleged  omission so made in  conformity  with
information  furnished  by such holder,  such  underwriter  or such  controlling
person in writing specifically for use in the preparation thereof.



                                       7







                             (ii) Each holder of Registrable Securities included
in a  registration  pursuant  to the  provisions  of  paragraph  (a) above  will
indemnify  and hold  harmless the  Company,  its  directors  and  officers,  any
controlling person and any underwriter from and against,  and will reimburse the
Company, its directors and officers,  any controlling person and any underwriter
with respect to, any and all loss, damage,  liability,  cost or expense to which
the Company or any controlling  person and/or any underwriter may become subject
under the Act or otherwise, insofar as such losses, damages, liabilities,  costs
or expenses are caused by any untrue  statement or alleged  untrue  statement of
any material  fact  contained in such  registration  statement,  any  prospectus
contained therein or any amendment or supplement thereto, or arise out of or are
based upon the  omission or alleged  omission to state  therein a material  fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances in which they were made, not misleading, in each case
to the extent,  but only to the extent,  that such untrue  statement  or alleged
untrue  statement or omission or alleged  omission was so made in reliance  upon
and in strict conformity with written  information  furnished by or on behalf of
such holder specifically for use in the preparation thereof.

                             (iii)  Promptly  after  receipt  by an  indemnified
party  pursuant to the  provisions of paragraph (i) or (ii) of this Article 4 of
notice of the  commencement  of any action  involving the subject  matter of the
foregoing  indemnity  provisions such indemnified party will, if a claim thereof
is to be made against the indemnifying  party pursuant to the provisions of said
paragraph  (i)  or  (ii),   promptly  notify  the  indemnifying   party  of  the
commencement  thereof; but the omission to so notify the indemnifying party will
not relieve it from any  liability  which it may have to any  indemnified  party
otherwise than hereunder. In case such action is brought against any indemnified
party and it notifies the indemnifying  party of the commencement  thereof,  the
indemnifying  party shall have the right to  participate  in, and, to the extent
that it may wish, jointly with any other indemnifying party similarly  notified,
to assume the defense  thereof,  with counsel  satisfactory to such  indemnified
party,  provided,  however,  if the  defendants  in any action  include both the
indemnified  party and the  indemnifying  party and the indemnified  party shall
have  reasonably  concluded  that there may be legal  defenses  available  to it
and/or other  indemnified  parties  which are  different  from or in addition to
those available to the indemnified  party, or if there is a conflict of interest
which would prevent counsel for the  indemnifying  party from also  representing
the indemnified party, the indemnified party or parties have the right to select
separate  counsel to participate in the defense of such action on behalf of such
indemnified party or parties.  After notice from the indemnifying  party to such
indemnified  party  of its  election  so to  assume  the  defense  thereof,  the
indemnifying  party will not be liable to such indemnified party pursuant to the
provisions  of  said  




                                       8







paragraph  (i) or (ii) for any legal or other expense  subsequently  incurred by
such  indemnified  party in  connection  with the  defense  thereof  other  than
reasonable costs of  investigation,  unless (A) the indemnified party shall have
employed  counsel in accordance  with the provisions of the preceding  sentence,
(B) the indemnifying  party shall not have employed counsel  satisfactory to the
indemnified  party to represent the  indemnified  party within a reasonable time
after the notice of the commencement of the action or (C) the indemnifying party
has  authorized  the  employment  of counsel  for the  indemnified  party at the
expense of the indemnifying party.

               The Company's  agreements  with respect to Warrants or the Shares
in this  Article 4 shall  continue  in effect  regardless  of the  exercise  and
surrender of this Warrant.

incorporation,  without giving effect to its principles  regarding  conflicts of
