                    COMMON STOCK PURCHASE WARRANT CERTIFICATE

                            Dated: ___________, 1999

                 to Purchase _________ Shares of Common Stock of

                             BASE TEN SYSTEMS, INC.


         BASE TEN  SYSTEMS,  INC.,  a New Jersey  corporation  (the  "Company"),
hereby certifies that _______________,  its permissible transferees,  designees,
successors and assigns  (collectively,  the "Holder"),  for value  received,  is
entitled to purchase from the Company at any time commencing on __________, 1999
and  terminating on __________,  [2003 as to Additional  Warrants;  December 15,
2001 as to Amended Warrants] up to  _________________________(_________)  shares
(each a "Share" and  collectively  the "Shares") of the  Company's  common stock
(the "Common  Stock"),  at an exercise  price of $3.00 per Share (the  "Exercise
Price").  The number of Shares purchasable  hereunder and the Exercise Price are
subject to adjustment as provided in Section 4 hereof.

         1.       Exercise of Warrants.

                  (a) Upon  presentation  and  surrender  of this  Common  Stock
Purchase Warrant Certificate ("Warrant  Certificate" or "Certificate"),  or Lost
Certificate  Affidavit,  accompanied by a completed  Election to Purchase in the
form attached hereto as Exhibit A (the "Election to Purchase") duly executed, at
the principal office of the Company at One Electronics Drive, Trenton, NJ 08619,
Attn: Mr. Thomas E. Gardner, together with a check payable to the Company in the
amount of the Exercise Price multiplied by the number of Shares being purchased,
the Company or the Company's  Transfer  Agent as the case may be, shall,  within
two (2) trading days of receipt of the foregoing,  deliver to the Holder hereof,
certificates  of  fully  paid  and  non-assessable  Common  Stock  which  in the
aggregate  represent the number of Shares being  purchased;  provided,  however,
that the Holder may elect,  with the written consent of the Company which may be
granted or withheld in the Company's sole  discretion  (except that such consent
will not be required if (i) the prospectus included in an effective registration
statement covering resale of the Shares includes an untrue statement of material
fact or omits  to  state a  material  fact  required  to be  stated  therein  or
necessary to make the statement  therein,  in light of the  circumstances  under
which they were made,  not  misleading,  or (ii) resales of the Shares cannot be
made  pursuant to an effective  registration  statement in  compliance  with the
securities  laws  for any  other  reason),  to  utilize  the  cashless  exercise
provisions  set forth below in lieu of tendering the Exercise Price in cash. The
certificates  so delivered shall be in such  denominations  as may be reasonably
requested  by the  Holder and shall be  registered  in the name of the Holder or
such other name as shall be  designated  by the Holder.  All or less than all of
the Warrants  represented by this  Certificate  may be exercised and, in case of
the exercise of less than all, the Company,  upon surrender hereof,  will at the
Company's   expense  deliver  to  the  Holder  a  new  Warrant   Certificate  or
Certificates  (in such  denominations as may be requested by the Holder) of like
tenor and dated the date hereof  entitling said holder to purchase the number of
Shares  represented  by this  Certificate  which have not been  exercised and to
receive  Registration  Rights with respect to such Shares,  and all other rights
with respect to the shares which the Holder has on the date hereof.

                  (b) Cashless Exercise. Notwithstanding the foregoing provision
regarding  payment of the Exercise Price in cash, the Holder may elect,  subject
to the provisions of Section 1(a), to receive a reduced number of Shares in lieu
of tendering the Exercise  Price in cash. In such case,  the number of Shares to
be issued to the Holder shall be computed using the following formula:

                                   X = Y(A-B)
                                       ------
                                          A

where:  X = the number of Shares to be issued to the  Holder;  
        Y = the number of Shares to be exercised under this Warrant Certificate;
        A = the Market Value (defined below) of one share of Common Stock; and
        B = the Exercise Price.

                  (c) Mandatory  Exercise.  The Company shall be entitled on any
day occurring on and after [the first  anniversary of the closing date] on which
the closing bid price of the Common  Stock on each trading day during the twenty
(20)  consecutive  trading  day period  ending on the  trading  day  immediately
preceding  such date (such  twenty (20)  consecutive  trading  day period  being
referred  to herein as the  "Calculation  Period")  is equal to or greater  than
$4.00 per share (the "Trigger Price"), to deliver a written notice to the Holder
requiring  such  Holder to  exercise  all of the  Warrants  represented  by this
Certificate  on the date which is ten (10)  trading days  following  the date of
such notice (the "Exercise  Date");  provided,  however,  that the Company shall
have such  right if, and only if,  (x) for a period of thirty  (30)  consecutive
trading days prior to the  beginning of such  Calculation  Period and (y) at all
times during such Calculation  Period and continuing  through the Exercise Date,
the Shares are (1) authorized and reserved for issuance,  (2) listed for trading
on each  principal  exchange or market on which the shares of Common  Stock were
then traded, and (3) registered for resale pursuant to an effective registration
statement under the Securities Act; provided,  further, however, that the Holder
shall not be required to exercise the Warrants  represented by this  Certificate
with respect to any such notice unless the closing bid price of the Common Stock
on the trading day immediately  preceding the Exercise Date is at least equal to
$3.90 (the "Threshold  Price") and the aggregate of cash (and cash  equivalents)
as shown on the most recent  balance  sheet of the Company  filed by the Company
with the  Securities  and Exchange  Commission  pursuant to Section 15(d) of the
Securities  Exchange Act of 1934, as amended (the  "Exchange  Act") is less than
$5,000,000.

As used in this Section 1, "Market  Value" refers to the Current Market Value of
the Common  Stock on the day before the  Election to Purchase  and this  Warrant
Certificate are duly  surrendered to the Company for a full or partial  exercise
hereof.

         2.  Exchange,  Transfer and  Replacement.  (a) At any time prior to the
exercise  hereof,  this  Certificate  may be  exchanged  upon  presentation  and
surrender  to the  Company,  alone or with other  Certificates  of like tenor of
different  denominations  registered in the name of the same Holder, for another
Certificate or Certificates of like tenor in the name of such Holder exercisable
for  the  aggregate   number  of  Shares  as  the  Certificate  or  Certificates
surrendered.

                  (b)  Replacement  of  Warrant  Certificate.  Upon  receipt  of
evidence reasonably satisfactory to the Company of the loss, theft, destruction,
or  mutilation  of this Warrant  Certificate  and, in the case of any such loss,
theft,  or  destruction,  upon  delivery of an  indemnity  agreement  reasonably
satisfactory  in  form  and  amount  to  the  Company  (collectively,   a  "Lost
Certificate Affidavit"),  or, in the case of any such mutilation, upon surrender
and cancellation of this Warrant Certificate,  the Company, at its expense, will
execute and deliver in lieu thereof, a new Warrant Certificate of like tenor.

                  (c) Cancellation;  Payment of Expenses.  Upon the surrender of
this  Warrant   Certificate  in  connection  with  any  transfer,   exchange  or
replacement  as provided in this  Section 2, this Warrant  Certificate  shall be
promptly  canceled by the Company.  The Company  shall pay all taxes (other than
securities transfer taxes) and all other expenses (other than legal expenses, if
any,  incurred by the Holder or  transferees)  and charges payable in connection
with the preparation, execution and delivery of Warrant Certificates pursuant to
this Section 2.

                  (d) Warrant  Register.  The  Company  shall  maintain,  at its
principal  executive  offices (or at the offices of the  transfer  agent for the
Warrant  Certificate  or such  other  office or agency of the  Company as it may
designate  by  notice  to the  holder  hereof),  a  register  for  this  Warrant
Certificate (the "Warrant Register"), in which the Company shall record the name
and  address  of the  person in whose  name this  Warrant  Certificate  has been
issued,  as well as the name and address of each  permitted  transferee and each
prior owner of this Warrant Certificate.

         3. Rights and Obligations of Holders of this Certificate. The Holder of
this  Certificate  shall not, by virtue  hereof,  be entitled to any rights of a
stockholder in the Company, either at law or in equity; provided,  however, that
in the  event any  certificate  representing  shares  of  Common  Stock or other
securities  is issued to the holder  hereof upon  exercise of some or all of the
Warrants,  such holder  shall,  for all  purposes,  be deemed to have become the
holder of record of such  Common  Stock on the date on which  this  Certificate,
together with a duly executed  Purchase Form, was surrendered and payment of the
aggregate Exercise Price was made,  irrespective of the date of delivery of such
share certificate.

         4.       Adjustments.

                  (a)  Stock  Dividends,  Reclassifications,  Recapitalizations,
Etc. In the event the  Company:  (i) pays a dividend in Common  Stock or makes a
distribution in Common Stock, (ii) subdivides its outstanding  Common Stock into
a greater number of shares,  (iii) combines its outstanding  Common Stock into a
smaller  number of shares or (iv) increases or decreases the number of shares of
Common Stock  outstanding by  reclassification  of its Common Stock (including a
recapitalization  in  connection  with a  consolidation  or  merger in which the
Company is the continuing corporation), then (1) the Exercise Price, the Trigger
Price  and  the  Threshold  Price  on  the  record  date  of  such  division  or
distribution  or the  effective  date  of  such  action  shall  be  adjusted  by
multiplying  such  Exercise  Price,   Trigger  Price  and  Threshold  Price,  as
applicable,  by a fraction,  the  numerator  of which is the number of shares of
Common Stock  outstanding  immediately  before such event and the denominator of
which is the number of shares of Common Stock outstanding immediately after such
event,  and (2) the  number of shares of  Common  Stock for which  this  Warrant
Certificate may be exercised  immediately before such event shall be adjusted by
multiplying  such number by a fraction,  the  numerator of which is the Exercise
Price,  the Trigger Price or the Threshold  Price,  as  applicable,  immediately
before  such  event and the  denominator  of which is the  Exercise  Price,  the
Trigger Price or the Threshold  Price,  as  applicable,  immediately  after such
event.

                  (b) Cash Dividends and Other Distributions.  In the event that
at any time or from time to time the Company shall  distribute to all holders of
Common Stock (i) any dividend or other  distribution  of cash,  evidences of its
indebtedness,  shares of its capital stock or any other properties or securities
or (ii) any options,  warrants or other rights to subscribe  for or purchase any
of the foregoing  (other than in each case, (w) the issuance of any rights under
a shareholder rights plan, (x) any dividend or distribution described in Section
4(a), (y) any rights, options,  warrants or securities described in Section 4(c)
and (z) any cash dividends or other cash  distributions  from current earnings),
then the number of shares of Common  Stock  issuable  upon the  exercise of each
Warrant Certificate shall be increased to a number determined by multiplying the
number of shares of Common  Stock  issuable  upon the  exercise of such  Warrant
Certificate  immediately  prior to the  record  date for any  such  dividend  or
distribution by a fraction,  the numerator of which shall be such Current Market
Value (as hereinafter  defined) per share of Common Stock on the record date for
such  dividend  or  distribution,  and the  denominator  of which  shall be such
Current  Market  Value  per share of Common  Stock on the  record  date for such
dividend  or  distribution  less  the sum of (x) the  amount  of  cash,  if any,
distributed  per share of Common Stock and (y) the fair value (as  determined in
good faith by the Board of Directors of the Company,  whose  determination shall
be evidenced by a board resolution,  a copy of which will be sent to the Holders
upon  request) of the portion,  if any, of the  distribution  applicable  to one
share of Common Stock consisting of evidences of indebtedness,  shares of stock,
securities,  other  property,  warrants,  options or  subscription  or  purchase
rights;  and the  Exercise  Price shall be adjusted  to a number  determined  by
dividing the Exercise Price  immediately  prior to such record date by the above
fraction.  Such adjustments  shall be made whenever any distribution is made and
shall become effective as of the date of distribution, retroactive to the record
date for any such  distribution.  No  adjustment  shall be made pursuant to this
Section 4(b) which shall have the effect of  decreasing  the number of shares of
Common Stock  issuable upon exercise of each Warrant  Certificate  or increasing
the Exercise Price.

                  (c) Rights  Issue.  In the event that at any time or from time
to time the  Company  shall issue  rights,  options or  warrants  entitling  the
holders  thereof  to  subscribe  for  shares  of  Common  Stock,  or  securities
convertible  into or exchangeable or exercisable for Common Stock to all holders
of Common Stock  (other than in  connection  with the adoption of a  shareholder
rights  plan by the  Company)  without  any charge,  entitling  such  holders to
subscribe for or purchase shares of Common Stock at a price per share that as of
the record date for such issuance is less than the then Current Market Value per
share of Common  Stock,  the number of shares of Common Stock  issuable upon the
exercise of each Warrant  Certificate  shall be increased to a number determined
by multiplying  the number of shares of Common Stock  theretofore  issuable upon
exercise of each Warrant Certificate by a fraction, the numerator of which shall
be the number of shares of Common Stock  outstanding  on the date of issuance of
such rights, options, warrant or securities plus the number of additional shares
of Common Stock offered for  subscription  or purchase or into or for which such
securities that are issued are convertible, exchangeable or exercisable, and the
denominator  of which shall be the number of shares of Common Stock  outstanding
on the date of issuance of such rights, option,  warrants or securities plus the
total  number  of  shares of Common  Stock  which  the  aggregate  consideration
expected to be received by the Company  (assuming  the exercise or conversion of
all such rights,  options,  warrants or  securities)  would purchase at the then
Current  Market  Value  per  share of  Common  Stock.  In the  event of any such
adjustment,  the  Exercise  Price shall be adjusted  to a number  determined  by
dividing the Exercise  Price  immediately  prior to such date of issuance by the
aforementioned  fraction.  Such adjustment shall be made immediately  after such
rights,  options or warrants are issued and shall become effective,  retroactive
to the record date for the  determination  of  stockholders  entitled to receive
such  rights,  options,  warrants or  securities.  No  adjustment  shall be made
pursuant  to this  Section  4(c) which shall have the effect of  decreasing  the
number of shares of Common  Stock  purchasable  upon  exercise  or each  Warrant
Certificate or of increasing the Exercise Price.

                  (d)  Combination:  Liquidation.  (i)  Except  as  provided  in
Section  4(d)(ii) below, in the event of a Combination (as defined below),  each
Holder shall have the right to receive upon exercise of the Warrant Certificates
the kind and amount of shares of capital  stock or other  securities or property
which such Holder  would have been  entitled  to receive  upon or as a result of
such Combination had such Warrant  Certificate been exercised  immediately prior
to such  event  (subject  to further  adjustment  in  accordance  with the terms
hereof). Unless paragraph (ii) is applicable to a Combination, the Company shall
provide that the surviving or acquiring Person (the "Successor Company") in such
Combination will assume by written instrument the obligations under this Section
4 and the obligations to deliver to the Holder such shares of stock,  securities
or assets as, in  accordance  with the foregoing  provisions,  the Holder may be
entitled to acquire.  The  provisions of this Section  4(d)(i)  shall  similarly
apply to successive Combinations involving any Successor Company.  "Combination"
means an event in which the Company  consolidates with, mergers with or into, or
sells all or substantially  all of its assets to another Person,  where "Person"
means any individual, corporation, partnership, joint venture, limited liability
company,  association,  joint stock company, trust, unincorporated organization,
government or any agency or political  subdivision  thereof or any other entity,
but  shall  not  include  the sale of  substantially  all of the  assets  of the
Government Technology Division of the Company.

                  (ii) In the event of (x) a Combination where  consideration to
the holders of Common Stock in exchange  for their  shares is payable  solely in
cash or (y) the  dissolution,  liquidation  or  winding-up  of the Company,  the
Holders  shall  be  entitled  to  receive,   upon  surrender  of  their  Warrant
Certificates,  distributions  on an equal basis with the holders of Common Stock
or other securities  issuable upon exercise of the Warrant  Certificates,  as if
the Warrant  Certificates  had been exercised  immediately  prior to such event,
less the Exercise Price.  In case of any  Combination  described in this Section
4(d)(ii),   the  surviving  or  acquiring  Person  and,  in  the  event  of  any
dissolution,  liquidation  or  winding-up  of the Company,  the  Company,  shall
deposit  promptly  following the consummation of such combination or at the time
of such dissolution,  liquidation or winding-up with an agent or trustee for the
benefit of the Holders of the funds, if any, necessary to pay to the Holders the
amounts to which they are entitled as described above.  After such funds and the
surrendered  Warrant  Certificates  are  received,  the  Company is  required to
deliver  a  check  in  such  amount  as is  appropriate  (or,  in  the  case  of
consideration  other than cash, such other  consideration  as is appropriate) to
such  Person  or  Persons  as it may  be  directed  in  writing  by the  Holders
surrendering such Warrant Certificates.

                  (e) Notice of  Adjustment.  Whenever the Exercise  Price,  the
Trigger  Price or the Threshold  Price,  or the number of shares of Common Stock
and other property,  if any, issuable upon exercise of the Warrant  Certificates
is adjusted, as herein provided, the Company shall deliver to the holders of the
Warrant  Certificates  in  accordance  with  Section  10 a  certificate  of  the
Company's Chief Financial Officer setting forth, in reasonable detail, the event
requiring the adjustment and the method by which such  adjustment was calculated
(including  a  description  of the  basis on which  (i) the  Board of  Directors
determined the fair value of any evidences of indebtedness,  other securities or
property or warrants,  options or other subscription or purchase rights and (ii)
the Current Market Value of the Common Stock was  determined,  if either of such
determinations  were required),  and specifying the Exercise Price,  the Trigger
Price and the Threshold  Price,  as  applicable,  and number of shares of Common
Stock issuable upon exercise of Warrant Certificates after giving effect to such
adjustment.

                  (f) Purchase Price  Adjustment.  In the event that the Company
issues or sells any Common Stock or  securities  which are  convertible  into or
exchangeable for its Common Stock or any convertible securities, or any warrants
or other rights to subscribe  for or to purchase or any options for the purchase
of its Common  Stock or any such  convertible  securities  (other than shares or
options  issued or which may be issued  pursuant  to the  Company's  employee or
director  option plans or shares  issued upon  exercise of options,  warrants or
rights outstanding on the date of the Agreement and listed in the Company's most
recent periodic report filed under the Exchange Act or disclosed in Schedule 3.3
to the Purchase  Agreement) and other than the Second Closing (as defined in the
Purchase  Agreement) at an effective purchase price per share which is less than
the Current  Market Value of the Common Stock on the trading day next  preceding
such  issue or sale,  then in each  such  case,  the  Exercise  Price in  effect
immediately prior to such issue or sale shall be reduced effective  concurrently
with such issue or sale to an amount  determined  by  multiplying  the  Exercise
Price then in effect by a fraction,  (x) the numerator of which shall be the sum
of (1) the number of shares of Common  Stock  outstanding  immediately  prior to
such  issue or sale,  plus (2) the  number of shares of Common  Stock  which the
aggregate consideration received by the Company for such additional shares would
purchase at such Current Market Value then in effect; and (y) the denominator of
which shall be the number of shares of Common  Stock of the Company  outstanding
immediately after such issue or sale.

For the purposes of the foregoing adjustment, in the case of the issuance of any
convertible securities, warrants, options or other rights to subscribe for or to
purchase or exchange for, shares of Common Stock ("Convertible Securities"), the
maximum  number of shares of Common Stock  issuable upon  exercise,  exchange or
conversion of such  Convertible  Securities  shall be deemed to be  outstanding,
provided that no further  adjustment  shall be made upon the actual  issuance of
Common  Stock  upon  exercise,   exchange  or  conversion  of  such  Convertible
Securities.

The  number  of shares  which  may be  purchased  hereunder  shall be  increased
proportionately  to any reduction in Exercise  Price  pursuant to this paragraph
4(d),  so that after such  adjustments  the  aggregate  Exercise  Price  payable
hereunder for the increased  number of shares shall be the same as the aggregate
Exercise Price in effect just prior to such adjustment.

In the event of any such  issuance for a  consideration  which is less than such
fair market  value and also less than the  Exercise  Price then in effect,  than
there  shall  be only one such  adjustment  by  reason  of such  issuance,  such
adjustment  to be that which  results in the greatest  reduction of the Purchase
Price computed as aforesaid.

                  (g)  Notice of  Certain  Transactions.  In the event  that the
Company shall propose (a) to pay any dividend payable in securities of any class
to the  holders of its Common  Stock or to make any other  non-cash  dividend or
distribution to the holders of its Common Stock, (b) to offer the holders of its
Common Stock rights to subscribe for or to purchase any  securities  convertible
into  shares  of  Common  Stock or  shares  of stock of any  class or any  other
securities,  rights  or  options,  (c) to  effect  any  capital  reorganization,
reclassification,  consolidation  or merger affecting the class of Common Stock,
as a  whole,  or  (d)  to  effect  the  voluntary  or  involuntary  dissolution,
liquidation  or winding-up of the Company,  the Company  shall,  within the time
limits specified below,  send to each Holder a notice of such proposed action or
offer.  Such notice  shall be mailed to the Holders at their  addresses  as they
appear in the Warrant Register (as defined in Section 2(d)), which shall specify
the record date for the purposes of such dividend,  distribution  or rights,  or
the date such  issuance or event is to take place and the date of  participation
therein by the  holders of Common  Stock,  if any such date is to be fixed,  and
shall  briefly  indicate  the  effect of such  action on the number of shares of
Common  Stock and on the  number  and kind of any  other  shares of stock and on
other  property,  if any,  and the  number of  shares of Common  Stock and other
property,  if any,  issuable upon exercise of each Warrant  Certificate  and the
Exercise Price after giving effect to any adjustment pursuant to Section 4 which
will be  required  as a result of such  action.  Such  notice  shall be given as
promptly as possible and (x) in the case of any action  covered by clause (a) or
(b) above, at least 10 days prior to the record date for determining  holders of
the Common  Stock for  purposes  of such  action or (y) in the case of any other
such action,  at least 20 days prior to the date of the taking of such  proposed
action or the date of  participation  therein by the  holders  of Common  Stock,
whichever shall be the earlier.

                  (h) Current Market Value.  "Current Market Value" per share of
Common Stock or any other  security at any date means (i) if the security is not
registered under the Exchange Act, (a) the value of the security,  determined in
good faith by the Board of  Directors  of the Company and  certified  in a board
resolution,  based  on the  most  recently  completed  arm's-length  transaction
between  the  Company  and a Person  other than an  affiliate  of the Company or
between any two such  Persons  and the  closing of which  occurs on such date or
shall have occurred within the six-month  period  preceding such date, or (b) if
no such transaction shall have occurred within the six-month  period,  the value
of the security as determined by an independent  financial expert or (ii) if the
security is registered  under the Exchange Act, the average of the daily closing
bid prices (or the  equivalent  in an  over-the-counter  market) for each day on
which the  Common  Stock is traded for any  period on the  principal  securities
exchange or other  securities  market on which the Common  Stock is being traded
(each,  a "Trading  Day")  during the period  commencing  ten (10)  Trading Days
before  such date and ending on the date one day prior to such  date,  or if the
security  has been  registered  under  the  Exchange  Act for less than ten (10)
consecutive  Trading Days before such date, the average of the daily closing bid
prices (or such  equivalent)  for all of the  Trading  Days before such date for
which daily  closing bid prices are  available;  provided,  however  that if the
closing bid price is not determinable for at least five (5) Trading Days in such
period, the "Current Market Value" of the security shall be determined as if the
security were not registered under the Exchange Act.

                  (i) Other  Adjustments.  If the event of any other transaction
of the type  contemplated  by this Section 4, but not expressly  provided for by
the  provisions  hereof,  the  Board  of  Directors  of the  Company  will  make
appropriate  adjustment  in the  Exercise  Price,  the  Trigger  Price  and  the
Threshold Price so as to equitably protect the rights of the Holder.

                  (j) No Impairment of Holder's Rights. The Company will not, by
amendment  of  its  certificate  of  incorporation  or  bylaws  or  through  any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, except as contemplated hereby,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant Certificate,  but will at all times in good faith assist in the carrying
out of all such  terms and in the taking of all  action as may be  necessary  or
appropriate  in order to protect  the rights of the Holder  against  dilution or
other impairment.  Without limiting the generality of the foregoing, the Company
will not increase the par value of any shares of Common  Stock  receivable  upon
exercise of this Warrant above the Exercise Price then in effect.

         5.  Company's  Representations.  The  representations,  warranties  and
agreements  of the  Company  contained  in  Sections  3 and 4 of the  Securities
Purchase  Agreement  dated  December 4, 1997  ("Purchase  Agreement")  among the

contained  in  Sections  3 and 4 of the  Exchange  Agreement  dated  ___________
("Exchange  Agreement")  among the  Company,  the  initial  Holder and the other

         6. Registration  Rights.  The initial Holder is entitled to the benefit
of such  registration  rights in  respect  of the Shares as are set forth in the
Registration  Rights  Agreement  dated as of December 4, 1997 by and between the
Company, the Holder and the other parties thereto, including the right to assign
such rights to certain  assignees as set forth  therein.  The initial  Holder is
entitled to the benefit of such registration  rights in respect of the Shares as
are set forth in Section 5 of the Exchange Agreement.

         7. Issuance of Certificates.  Within two (2) trading days of receipt of
a duly completed  Election to Purchase form,  together with this Certificate and
payment of the Exercise  Price,  the Company,  at its expense,  will cause to be
issued in the name of and delivered to the Holder of this Warrant, a certificate
or certificates for the number of fully paid and non-assessable shares of Common
Stock to which that holder shall be entitled on such exercise.  In the event the
shares of Common  Stock are not timely  delivered  to the  Holder,  the  Company
agrees to (a)  indemnify  Holder for all damages,  including  consequential  and
special  damages,  lost  profits and  expenses,  including  legal fees,  and (b)
beginning  on the fifth  (5th) day  following  the  Company's  receipt of a duly
completed  Election to Purchase form, pay a default premium of 2% per day of the
value of underlying  shares  (based on the highest  closing price during the two
(2) day period preceding the date of surrender of the Warrant  Certificate).  In
lieu of issuance of a fractional share upon any exercise hereunder,  the Company
will pay the cash value of that fractional share, calculated on the basis of the
Exercise  Price.  Prior to  registration  of the  resale of the shares of Common
Stock underlying this Warrant  Certificate,  all such certificates  shall bear a
restrictive legend to the effect that the Shares represented by such certificate
have not been  registered  under the Securities Act, and that the Shares may not
be sold or  transferred  in the  absence of such  registration  or an  exemption
therefrom, such legend to be substantially in the form of the bold-face language
appearing at the top of Page 1 of this Warrant Certificate.

         8.  Disposition  of  Warrants  or Shares.  The  Holder of this  Warrant
Certificate, each transferee hereof and any holder and transferee of any Shares,
by his or its acceptance thereof, agrees that no public distribution of Warrants
or Shares will be made in violation of the  provisions  of the  Securities  Act.
Furthermore,  it shall be a condition to the  transfer of the Warrants  that any
transferee thereof deliver to the Company his or its written agreement to accept
and be bound by all of the  relevant  terms  and  conditions  contained  in this
Warrant Certificate.

         9. Merger or  Consolidation.  The Company will not merge or consolidate
with or into any other corporation,  or sell or otherwise transfer its property,
assets and business substantially as an entirety to another corporation,  unless
the  corporation  resulting  from  such  merger  or  consolidation  (if  not the
Company),  or such transferee  corporation,  as the case may be, shall expressly
assume, by supplemental agreement reasonably  satisfactory in form and substance
to the Holder, the due and punctual performance and observance of each and every
covenant and condition of this Warrant  Certificate to be performed and observed
by the Company.

         10. Notices.  Except as otherwise specified herein to the contrary, all
notices,  requests,  demands and other communications  required or desired to be
given  hereunder  shall only be  effective  if given in writing by  certified or
registered  U.S.  mail with return  receipt  requested and postage  prepaid;  by

mailed by certified or  registered  U.S.  mail as  specified  above;  (b) on the
business day immediately  following  deposit with a private  overnight  delivery

Notwithstanding  the time of effectiveness of notices set forth in this Section,
an Election to Purchase shall not be deemed  effectively given until it has been
duly completed and submitted to the Company  together with the original  Warrant
Certificate  to be exercised  and payment of the Exercise  Price in a manner set
forth in this Section.

         11. Governing Law. This Agreement shall be governed by and construed in
accordance  with the law of the  Company's  jurisdiction  of  incorporation  (in
respect of matters of corporation law) and the laws of the State of New York (in
respect of all other  matters)  applicable to contracts made and to be performed
in the  State  of New  York.  The  parties  hereto  irrevocably  consent  to the
jurisdiction of the United States federal courts and state courts located in the
Borough of Manhattan in the State of New York in any suit or proceeding based on
or arising  under this  Agreement or the  transactions  contemplated  hereby and
irrevocably  agree that all claims in respect of such suit or proceeding  may be
determined  in such courts.  The Company and the Holder  irrevocably  waives the
defense of an  inconvenient  forum to the maintenance of such suit or proceeding
in such forum.  The Company and the Holder further agree that service of process
upon the Company or the Holder, as applicable, mailed by the first class mail in
accordance with Section 10 shall be deemed in every respect effective service of
process  upon  the  Company  or the  Holder  in any suit or  proceeding  arising
hereunder.  Nothing  herein shall affect the Holder's  right to serve process in
any other  manner  permitted  by law.  The  parties  hereto  agree  that a final
non-appealable  judgment in any such suit or proceeding  shall be conclusive and
may be enforced in other  jurisdictions by suit on such judgment or in any other
lawful manner.  The parties hereto  irrevocably waive any right to trial by jury
under applicable law.

         12. Limitations on Holdings.  The Warrant shall not be exercisable by a
Holder to the extent (but only to the extent) that, if exercised by such Holder,
the  Holder  would   beneficially   own  in  excess  of  4.9%  (the  "Applicable
Percentage")  of the  shares  of  Common  Stock.  To the  extent  the  foregoing
limitation applies,  the determination of whether this Warrant Certificate shall
be exercisable (vis-a-vis other securities owned by such Holder) shall be in the
sole discretion of the Holder and submission of an Election to Purchase shall be
deemed to be the Holder's  determination  of whether the Warrant  Certificate is
exercisable  in  whole  or  in  part,  subject  to  such  aggregate   percentage
limitation.  No prior inability to exercise the Warrant Certificate  pursuant to
this Section  shall have any effect on the  applicability  of the  provisions of
this  Section  with  respect  to any  subsequent  determination  of  ability  to
exercise.  For  the  purposes  of this  Section,  beneficial  ownership  and all
calculations,  including  without  limitation,  with respect to  calculations of
percentage ownership shall be determined in accordance with Section 13(d) of the
Exchange Act, and Regulation  13D-G  thereunder.  The provisions of this Section
may  be  amended  and/or  implemented  in a  manner  otherwise  than  in  strict
conformity  with the terms of this  Section  with the  approval  of the Board of
Directors  of the Company and the  affected  Holder:  (i) to cure any  ambiguity
herein,  to  correct  this  subsection  (or any  portion  thereof)  which may be
defective or inconsistent  with the intended  Applicable  Percentage  beneficial
ownership  limitation  herein  contained  or  to  make  changes  or  supplements
necessary  or desirable to properly  give effect to such  Applicable  Percentage
limitation;  and (ii) with respect to any other matter, with the further consent
of the holders of majority of the then  outstanding  shares of Common Stock; the
provisions  of this  Section  may be waived with the  approval  of the  affected
Holder  upon  ninety  (90) days prior  written  notice  from such  Holder to the
Company.  The  limitations  contained in this Section shall apply to a successor
Holder of this Warrant if, and to the extent,  elected by such successor  Holder
concurrently with its acquisition of this Warrant,  such election to be promptly
confirmed in writing to the Company (provided no transfer or series of transfers
to a  successor  Holder  or  Holders  shall  be used by a Holder  to  evade  the
limitations contained herein).

         13. Successors and Assigns.  This Warrant  Certificate shall be binding
upon and shall inure to the benefit of the parties  hereto and their  respective
successors and permitted assigns.

         14.  Headings.  The  headings  of  various  sections  of  this  Warrant
Certificate  have been  inserted  for  reference  only and shall not  affect the
meaning or construction of any of the provisions hereof.

         15. Severability.  If any provision of this Warrant Certificate is held
to be unenforceable  under applicable law, such provision shall be excluded from
this Warrant Certificate, and the balance hereof shall be interpreted as if such
provision were so excluded.

         16. Modification and Waiver. This Warrant Certificate and any provision
hereof may be amended, waived, discharged or terminated only by an instrument in
writing signed by the Company and the Holder.

         17. Specific  Enforcement.  The Company and the Holder  acknowledge and
agree  that  irreparable  damage  would  occur  in  the  event  that  any of the
provisions of this Warrant  Certificate  were not  performed in accordance  with
their specific terms or were otherwise  breached.  It is accordingly agreed that
the parties shall be entitled to an injunction or injunctions to prevent or cure
breaches  of  the  provisions  of  this  Warrant   Certificate  and  to  enforce
specifically  the terms and  provisions  hereof,  this being in  addition to any
other remedy to which either of them may be entitled by law or equity.

         18.  Assignment.   This  Warrant  Certificate  may  be  transferred  or
assigned,  in whole or in  part,  at any time and from  time to time by the then
Holder by submitting  this Warrant to the Company  together with a duly executed
Assignment  in  substantially  the form and  substance of the Form of Assignment
which  accompanies  this Warrant  Certificate  and, upon the  Company's  receipt
hereof, and in any event, within three (3) business days thereafter, the Company
shall issue a Warrant Certificate to the Holder to evidence that portion of this
Warrant Certificate, if any as shall not have been so transferred or assigned.


         IN WITNESS WHEREOF,  the Company has caused this Warrant Certificate to
be duly  executed,  manually or by facsimile,  by one of its officers  thereunto
duly authorized.
