     Item 3. Source and Amount of Funds or Other Consideration.

     In March  1996,  the  Issuer  was formed as a  wholly-owned  subsidiary  of
Environmental.  Prior to the Issuer's  initial public  offering in June 1996, in
exchange  for the  issuance of  15,000,000  shares of Common Stock of the Issuer
(representing  100% of the  outstanding  shares of Common Stock of the Issuer at
the  time),  Environmental  contributed  to the Issuer (i) all of the assets and
properties (including joint working proposals, quotations and bids in respect to
projects and contracts awarded for feasibility  studies),  subject to all of the
liabilities,  of its  operating  divisions  relating  to  certain  environmental
remediation  technologies  and  the  exploitation  of such  technologies  in all
commercial and governmental applications;  (ii) all of the outstanding shares of
the capital stock of certain corporate  entities engaged in similar  businesses;
and (iii) a $3.0 million  promissory  note. As a result of the Issuer's  initial
public offering in June 1996,  Environmental's  beneficial ownership interest in
the Issuer was reduced from 100% to 73%.

     In December 1996, as part of a corporate  restructuring  to consolidate all
of  its  current   environmental   technology   businesses  within  the  Issuer,
Environmental  transferred  to the Issuer all of the capital stock of Separation
and Commodore CFC Technologies, Inc. In addition,  Environmental assigned to the
Issuer notes  aggregating  $976,200 at December 2, 1996,  representing  advances
previously  made by  Environmental  to  Separation.  In  consideration  for such
transfers,  the Issuer  paid  Environmental  $3.0  million in cash and issued to
Environmental a warrant expiring  December 1, 2003 to purchase  7,500,000 shares
of Common Stock of the Issuer at an exercise  price of $15.00 per share,  valued
at $2.4 million.  Such warrant was subsequently  amended to, among other things,
reduce the exercise price thereof from $15.00 per share to $10.00 per share.

     From May 1997 through  February 1998, in a series of private  transactions,
Environmental  sold an aggregate of 6,801,856 of the 15,000,000 shares of Common
Stock of the Issuer that it owned to certain private investors.

     In September 1997,  Environmental provided a $4.0 million unsecured loan to
the Issuer,  evidenced by the  Issuer's 8%  convertible  subordinated  note (the
"Convertible  Note").  Pursuant to the terms of the Convertible Note, the Issuer
was  obligated to pay  Environmental  interest only at the rate of 8% per annum,
payable quarterly. Unless converted into Common Stock of the Issuer at any time,
the  unpaid  principal  amount  of the  Convertible  Note  was due and  payable,
together  with  accrued and unpaid  interest,  on August 31,  2002.  Payments of
principal and accrued  interest under the Convertible  Note was  subordinated to
all other  indebtedness for money borrowed of the Issuer.  Environmental had the
right to convert the Convertible  Note into shares of Common Stock of the Issuer
at a conversion  price of $3.89 per share.  Such  conversion  price was fixed at
approximately  85% of the five day average closing bid price of the Common Stock
($4.575  per  share)  prior to August  22,  1997,  the date  that the  executive
committees of the respective Boards of Directors of Environmental and the Issuer
authorized  such loan.  In  connection  with the $4.0 million  loan,  the Issuer
issued  Environmental a five-year warrant to purchase 1,000,000 shares of Common
Stock of the Issuer at an  exercise  price of $5.0325  per share  (approximately
110% of the $4.575 five day average  closing bid price of the Common Stock prior
to August 22, 1997).

     In March 1998, the Issuer prepaid $2.0 million of the  Convertible  Note by
(i) paying  Environmental  the sum of $500,000 in cash and (ii)  transferring to
Environmental a promissory  note, dated August 30, 1996, in the principal amount
of $1.5 million.  To induce  Environmental to accept the Issuer's  prepayment of
$2.0 million of the  Convertible  Note (and thereby give up the right to convert
$2.0  million of the  Convertible  Note into Common  Stock of the  Issuer),  the
Issuer issued to Environmental  an additional  warrant to purchase up to 514,000
shares of Common  Stock of the Issuer at an  exercise  price of $4.50 per share.
Such exercise price was fixed at approximately 110% of the closing sale price of
the Common Stock on February 20, 1998, the trading day immediately  prior to the
date the Board of Directors  of  Environmental  approved  such  prepayment.  The
estimated fair value of such warrant is approximately $340,000.

     In February 1998, Environmental provided a $5,450,000 unsecured loan to the
Issuer,  evidenced by the Issuer's 8%  non-convertible  note (the  "Intercompany
Note").  Pursuant to the terms of the Intercompany Note,  interest on the unpaid
principal  balance of the  Intercompany  Note was  payable at the rate of 8% per
annum semiannually in cash. The unpaid principal amount of the Intercompany Note
was due and payable,  together with accrued and unpaid interest,  on the earlier
to occur of (a) December 31, 1999, or (b) consummation of any public offering or
private  placement of securities of the Issuer with net proceeds  aggregating in
excess of $6.0 million,  other than in respect of working  capital  financing or
secured  financing of assets  received by the Issuer in the  ordinary  course of
business from any bank or other  lending  institution.  In  connection  with the
loan, the Issuer  amended and restated in its entirety the five-year  warrant to
purchase 7,500,000 shares of Common Stock issued to Environmental on December 2,
1996 to,  among other  things,  reduce the  exercise  price of the warrant  from
$15.00  per share to  $10.00  per  share.  In  addition,  the  Issuer  issued to
Environmental an additional  five-year  warrant to purchase  1,500,000 shares of
Common  Stock of the  Issuer at an  exercise  price of $10.00  per  share.  Such
warrant was  subsequently  amended to reduce the  exercise  price  thereof  from
$10.00 per share to $1.50 per share.

     Effective  September 28, 1998, the Issuer repaid the remaining  balances on
the Convertible  Note and the  Intercompany  Note, which totaled an aggregate of
$6,755,864,  by (i) transferring  10,000,000  shares of Separation


                               Page 7 of 15 Pages
<PAGE>

common stock,  representing  87% of  Separation's  outstanding  common stock, to
Commodore  Environmental  Services,  LLC, a Delaware limited  liability  company
wholly-owned  by  Environmental;  (ii) issuing 20,909 shares of newly created 6%
Series B Convertible  Preferred Stock, par value $0.001 per share (the "Series B
Preferred  Stock"),  10,189  shares of newly  created  6%  Series C  Convertible
Preferred  Stock,  par value $0.001 per share (the "Series C Preferred  Stock"),
and 20,391 shares of newly created 6% Series D Convertible  Preferred Stock, par
value  $0.001  per share  (the  "Series D  Preferred  Stock"),  of the Issuer to
Environmental; (iii) assigning to Environmental an account receivable due to the
Issuer from Separation in the amount of $357,000;  and (vi) amending the warrant
held by Environmental to purchase 1,500,000 shares of Common Stock of the Issuer
to reduce the exercise price thereof from $10.00 per share to $1.50 per share.

     Pursuant to certain anti-dilution provisions contained in the Environmental
Warrants,  the  respective  per share  exercise  prices of and  number of shares
subject to the Environmental Warrants were adjusted in November 1999 as follows:

Street,  Suite 3400,  New York, New York 10155.  Mr. Karlik has not,  during the
past five years,  been  convicted in a criminal  proceeding  (excluding  traffic
violations or similar  misdemeanors).  Mr. Karlik was not,  during the past five

577,500 shares of Common Stock of the Issuer  underlying  currently  exercisable
stock options granted to Mr. Hannesson by the Issuer under its 1998 Stock Option

of the  issued  and  outstanding  shares  of  Environmental  common  stock,  Mr.
Hannesson is deemed to be the indirect  beneficial  owner of 2,983,650 shares of

currently exercisable, nor are they exercisable within 60 days from November 24,
1999.

     (c) On  November  24,  1999,  Environmental  elected to convert  all of the
issued and outstanding  shares of Series B Preferred  Stock,  Series C Preferred
Stock and Series D Preferred  Stock into an  aggregate  of  7,258,533  shares of
Common  Stock of the  Issuer,  and such  shares of Common  Stock were  issued to

2,987,000  shares of Common Stock of the Issuer at a  conversion  price of $0.70
per share,  the Series C Preferred Stock was converted into 1,358,533  shares of
Common  Stock of the Issuer at a  conversion  price of $0.75 per share,  and the
Series D Preferred Stock was converted into 2,913,000  shares of Common Stock of
the  Issuer  at a  conversion  price of $0.70 per  share.  The  transaction  was
effected in New York City on November  24, 1999 by  Environmental's  delivery to
the  Issuer of a notice of  conversion  with  respect  to all of such  preferred
stock,  whereupon the Issuer caused its transfer  agent to issue an aggregate of
7,258,533 shares of its Common Stock to Environmental as of such date.

goals.  Pursuant  to  the  terms  of the  Hannesson  Employment  Agreement,  Mr.
Hannesson is entitled to participate in the bonus plans of the Issuer, which may
from time to time include additional grants of stock options or other securities
to Mr.  Hannesson in  connection  with his service as an  executive  officer and
director of the  Issuer,  which  securities  may be  exchangeable  for shares of
Common Stock of the Issuer.

No. __                                                            514,000 Shares

     THIS CERTIFIES that, for value received,  Commodore Environmental Services,
Inc. (the  "Holder"),  is entitled to subscribe for and purchase from  Commodore
Applied  Technologies,  Inc., a Delaware  corporation (the "Company"),  upon the
terms and  conditions  set forth herein,  at any time or from time to time after
the date  hereof,  and before  5:00 P.M. on March 31,  2003,  New York time (the
"Exercise  Period"),  Five Hundred Fourteen Thousand (514,000) shares, par value
$.001 per share, of the Company ("Common Stock"),  at an exercise price of $4.50
per share (the "Exercise Price").  This Warrant is being issued in consideration
of the Holder's  acceptance of the Company's partial  prepayment of $2.0 million
in principal amount of the Company's 8% convertible subordinated note due August
31, 2002,  evidencing the Holder's $4.0 million unsecured loan to the Company in
September  1997. As used herein the term "this  Warrant"  shall mean and include
this Warrant and any Warrant or Warrants  hereafter  issued as a consequence  of
the exercise or transfer of this Warrant in whole or in part.

     The number of shares of Common Stock issuable upon exercise of the Warrants
(the "Warrant  Shares") and the Exercise Price may be adjusted from time to time
as hereinafter set forth.

     1. This Warrant may be  exercised  during the  Exercise  Period,  as to the
whole or any lesser number of the respective whole Warrant Shares, as follows:

          (a) by the surrender of this Warrant (with the form of election at the
     end hereof duly  executed) to the Company at its office as set forth in the
     form of election  attached hereto,  or at such other place as is designated
     in writing by the  Company,  together  with a certified  or bank  cashier's
     check  payable  to the  order  of the  Company  in an  amount  equal to the
     Exercise  Price  multiplied by the number of respective  Warrant Shares for
     which this Warrant is being exercised; or



                                       1
<PAGE>

          (b) by surrender of this Warrant (with the notice of cashless exercise
     at the end hereof duly  executed) to the Company at its office as set forth
     in the notice of cashless  exercise attached hereto, or at such other place
     as is  designated  in writing by the  Company,  in which  event the Company
     shall  issue to the  Holder  the number of  Warrant  Shares  determined  as
     follows:

               X = Y (A-B)/A

        where:

               X = the number of Warrant Shares to be issued to the Holder.

               Y = the  number of  Warrant  Shares  with  respect  to which this
               Warrant is being exercised.

               A = the  closing  sale price of the Common  Stock for the trading
               day immediately prior to the date of exercise.

               B = the Exercise Price.

     2. Upon each exercise of the Holder's  rights to purchase  Warrant  Shares,
either  pursuant to Section 1(a) or (b) above,  the Holder shall be deemed to be
the  holder  of record  of the  Warrant  Shares  issuable  upon  such  exercise,
notwithstanding  that the transfer  books of the Company shall then be closed or
certificates  representing such Warrant Shares shall not then have been actually
delivered  to the  Holder.  For  purposes  of Rule  144  promulgated  under  the
Securities Act of 1933, as amended (the "Act"),  it is intended,  understood and
acknowledged that the Warrant Shares issued in a cashless  exercise  transaction
pursuant  to Section  1(b) above  shall be deemed to have been  acquired  by the
Holder,  and the holding  period for the Warrant  Shares shall be deemed to have
been commenced,  on the issue date of the Warrant.  As soon as practicable after
each such  exercise of this Warrant and payment of the Holder a  certificate  or
certificates  for the Warrant Shares issuable upon such exercise,  registered in
the name of the Holder or its  designee.  If the Warrant  should be exercised in
part only, the Company shall,  upon surrender of this Warrant for  cancellation,
execute and deliver a new Warrant evidencing the right of the Holder to purchase
the  balance of the Warrant  Shares (or  portions  thereof)  subject to purchase
hereunder.

     3. Any  Warrants  issued  upon the  transfer  or  exercise  in part of this
Warrant shall be numbered and shall be registered in a Warrant  Register as they
are issued.  The Company shall be entitled to treat the registered holder of any
Warrant on the Warrant  Register as the Owner in fact  thereof for all  purposes
and shall not be bound to recognize  any equitable or other claim to or interest
in such Warrant on the part of any other person, and shall not be liable for any
registration or transfer of Warrants which are registered or to be registered in
the name of a  fiduciary  or the  nominee of a  fiduciary  unless  made with the
actual  knowledge that a fiduciary or nominee is committing a breach of trust in
requesting such  registration  or transfer,  or with the knowledge of such facts
that its  participation  therein  amounts to bad faith.  This  Warrant  shall be

transferable  only on the  books  of the  Company  upon  delivery  thereof  duly
endorsed by the Holder or by his duly authorized attorney or representative,  or
accompanied  by proper  evidence of  succession,  assignment,  or  authority  to
transfer.  In all cases or transfer  by an  attorney,  executor,  administrator,
guardian, or other legal representative,  duly authenticated  evidence of his or
its authority shall be produced.  Upon any registration of transfer, the Company
shall  deliver a new Warrant or Warrants to the person  entitled  thereto.  This
Warrant  may be  exchanged,  at the option of the Holder  thereof,  for  another
Warrant,  or other  Warrants  of  different  denominations,  of like  tenor  and
representing  in the  aggregate  the right to  purchase a like number of Warrant
Shares  (or  portions  thereof),  upon  surrender  to the  Company  or its  duly
authorized  agent.  Notwithstanding  the  foregoing,  the Company  shall have no
obligation to cause Warrants to be transferred on its books to any person if, in
the opinion of counsel to the Company,  such  transfer  does not comply with the
provisions of the Act and the rules and regulations thereunder.

     4. The Company  shall at all times  reserve and keep  available  out of its
authorized  and unissued  Common Stock,  solely for the purpose of providing for
the exercise of the rights to purchase all Warrant  Shares  granted  pursuant to
the Warrants, such number of shares of Common Stock as shall, from time to time,
be sufficient  therefor.  The Company  covenants that all shares of Common Stock
issuable upon exercise of this Warrant,  upon receipt by the Company of the full
Exercise Price  therefor if such exercise is pursuant to Section 1(a) above,  or
upon receipt by the Company of the notice of cashless  exercise duly executed if
such exercise is pursuant to Section 1(b) above, shall be validly issued,  fully
paid, nonassessable, and free of preemptive rights.

     5. (a) In case the  Company  shall at any time after the date the  Warrants
were first issued (i) declare a dividend on the outstanding Common Stock payable
in shares of its capital  stock,  (ii) subdivide the  outstanding  Common Stock,
(iii) combine the outstanding  Common Stock into a smaller number of shares,  or
(iv) issue any shares of its  capital  stock by  reclassification  of the Common
Stock (including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing corporation),  then, in each case,
the Exercise  Price,  and the number of Warrant Shares issuable upon exercise of
this  Warrant,  in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination, or reclassification,  shall
be proportionately adjusted so that the Holder after such time shall be entitled
to receive the aggregate  number and kind of shares  which,  if such Warrant had
been  exercised  immediately  prior to such time,  he would have owned upon such
exercise and been entitled to receive by virtue of such  dividend,  subdivision,
combination,  or  reclassification.  Such adjustment shall be made  successively
whenever any event listed above shall occur.

     (b) In case the Company  shall issue or fix a record date for the  issuance
to all holders of Common Stock of rights,  options, or warrants to subscribe for
or purchase Common Stock (or securities  convertible  into or  exchangeable  for
Common Stock) at a price per share (or having a conversion or exchange price per
share, if a security  convertible  into or  exchangeable  for Common Stock) less
than the Exercise Price per share of Common Stock on such record date,  then, in
each case,  the  Exercise  Price shall be adjusted by  multiplying  the Exercise
Price  in  effect


                                       3
<PAGE>

immediately  prior to such  record date by a fraction,  the  numerator  of which
shall be the number of shares of Common  Stock  outstanding  on such record date
plus the number of shares of Common Stock which the aggregate  offering price of
the total  number of shares of Common  Stock so to be offered (or the  aggregate
initial  conversion  or  exchange  price  of  the  convertible  or  exchangeable
securities so to be offered) would  purchase at such current  Exercise Price and
the  denominator  of  which  shall be the  number  of  shares  of  Common  Stock
outstanding  on such record date plus the number of additional  shares of Common
Stock to be offered for  subscription or purchase (or into which the convertible
or  exchangeable  securities  so to be  offered  are  initially  convertible  or
exchangeable).  Such adjustment  shall become effective at the close of business
on such record date; provided, however, that, to the extent the shares of Common
Stock (or  securities  convertible  into or  exchangeable  for  shares of Common
Stock) are not  delivered,  the  Exercise  Price shall be  readjusted  after the
expiration  of such  rights,  options,  or  warrants  (but only with  respect to
Warrants  exercised  after such  expiration),  to the Exercise Price which would
then be in effect had the  adjustments  made upon the  issuance of such  rights,
options,  or warrants been made upon the basis of delivery of only the number of
shares of Common  Stock (or  securities  convertible  into or  exchangeable  for
shares of Common Stock) actually issued.  In case any subscription  price may be
paid in a consideration part or all of which shall be in a form other than cash,
the value of such  consideration  shall be as  determined  in good  faith by the
board of directors  of the  Company,  whose  determination  shall be  conclusive
absent manifest  error.  Shares of Common Stock owned by or held for the account
of the Company or any majority-owned  subsidiary shall not be deemed outstanding
for the purpose of any such computation.

     (c) In case the Company  shall  distribute  to all holders of Common  Stock
(including  any such  distribution  made to the  stockholders  of the Company in
connection with a consolidation or merger in which the Company is the continuing
corporation)  evidences of its indebtedness or assets (other than cash dividends
or distributions  and dividends  payable in shares of Common Stock),  or rights,
options,  or warrants to subscribe for or purchase  Common Stock,  or securities
convertible  into or exchangeable  for shares of Common Stock  (excluding  those
with respect to the  issuance of which an  adjustment  of the Exercise  Price is
provided  pursuant to Section 5(b)  hereof),  then,  in each case,  the Exercise
Price shall be adjusted by multiplying the Exercise Price in effect  immediately
prior to the record  date for the  determination  of  stockholders  entitled  to
receive such  distribution  by a fraction,  the  numerator of which shall be the
Exercise  Price per share of Common  Stock on such  record  date,  less the fair
market  value (as  determined  in good  faith by the board of  directors  of the
Company,  whose  determination shall be conclusive absent manifest error) of the
portion of the evidences of indebtedness  or assets so to be distributed,  or of
such rights,  options,  or warrants or convertible or  exchangeable  securities,
applicable  to one share,  and the  denominator  of which shall be such  current
Exercise Price per share of Common Stock. Such adjustment shall be made whenever
any such distribution is made, and shall become effective on the record date for
the determination of shareholders entitled to receive such distribution.

     (d) In case the  Company  shall  issue  shares of Common  Stock or  rights,
options,  or warrants to subscribe for or purchase  Common Stock,  or securities
convertible  into or exchangeable for Common Stock  (excluding  shares,  rights,
options,  warrants, or convertible or


                                       4
<PAGE>

exchangeable  securities  issued or issuable (i) in any of the transactions with
respect to which an  adjustment  of the Exercise  Price is provided  pursuant to
Sections 5(a),  5(b) or 5(c) above,  (ii) upon exercise of the Warrants or (iii)
to  management  or employees of the Company up to a maximum  amount of shares of
Common  Stock),  at a price per share  (determined,  in the case of such rights,
options,  warrants, or convertible or exchangeable  securities,  by dividing (x)
the total amount received or receivable by the Company in  consideration  of the
sale  and  issuance  of  such  rights,  options,  warrants,  or  convertible  or
exchangeable securities, plus the minimum aggregate consideration payable to the
Company  upon  exercise,  conversion,  or exchange  thereof,  by (y) the maximum
number of shares covered by such rights,  options,  warrants,  or convertible or
exchangeable securities) lower than the Exercise Price per share of Common Stock
in effect  immediately prior to such issuance,  then the Exercise Price shall be
reduced on the date of such issuance to a price (calculated to the nearest cent)
determined by multiplying the Exercise Price in effect immediately prior to such
issuance by a fraction, (iii) the numerator of which shall be an amount equal to
the sum of (A) the  number of shares of  Common  Stock  outstanding  immediately
prior  to  such  issuance  plus  (B)  the  quotient  obtained  by  dividing  the
consideration  received  by the  Company  upon  such  issuance  by such  current
Exercise  Price,  and (iv) the denominator of which shall be the total number of
shares of Common Stock  outstanding  immediately  after such  issuance.  For the
purposes of such adjustments,  the maximum number of shares which the holders of
any such rights,  options,  warrants, or convertible or exchangeable  securities
shall be entitled to initially  subscribe for or purchase or convert or exchange
such securities into shall be deemed to be issued and outstanding as of the date
of such issuance,  and the consideration  received by the Company therefor shall
be deemed to be the  consideration  received  by the  Company  for such  rights,
options,  warrants, or convertible or exchangeable securities,  plus the minimum
aggregate consideration or premiums stated in such rights, options, warrants, or
convertible  or  exchangeable  securities  to be  paid  for the  shares  covered
thereby.  No further  adjustment of the Exercise Price shall be made as a result
of the actual  issuance of shares of Common  Stock on  exercise of such  rights,
options,  or  warrants or on  conversion  or  exchange  of such  convertible  or
exchangeable  securities.  On the expiration or the  termination of such rights,
options,  or warrants,  or the termination of such right to convert or exchange,
the  Exercise  Price  shall be  readjusted  (but only with  respect to  Warrants
exercised  after such expiration or termination) to such Exercise Price as would
have  obtained  had the  adjustments  made  upon the  issuance  of such  rights,
options,  warrants, or convertible or exchangeable securities been made upon the
basis of the  delivery  of only the  number of shares of Common  Stock  actually
delivered  upon the  exercise of such rights,  options,  or warrants or upon the
conversion or exchange of any such  securities;  and on any change of the number
of shares of Common  Stock  deliverable  upon the  exercise of any such  rights,
options,   or  warrants  or  conversion  or  exchange  of  such  convertible  or
exchangeable securities or any change in the consideration to be received by the
Company upon such exercise,  conversion, or exchange, including, but not limited
to, a change resulting from the antidilution  provisions  thereof,  the Exercise
Price,  as then in effect,  shall forthwith be readjusted (but only with respect
to Warrants  exercised  after such change) to such Exercise  Price as would have
been  obtained  had an  adjustment  been made upon the  issuance of such rights,
options,  or warrants not  exercised  prior to such change,  or  securities  not
converted or exchanged  prior to such  change,  on the basis of such change.  In
case the Company shall issue shares of Common Stock or any such rights, options,
warrants,  or  convertible  or  exchangeable


                                       5
<PAGE>

securities  for a  consideration  consisting,  in whole or in part,  of property
other  than  cash  or its  equivalent,  then  the  "price  per  share"  and  the
"consideration  received by the Company"  for purposes of the first  sentence of
this Section 5(d) shall be as determined in good faith by the board of directors
of the Company,  whose  determination shall be conclusive absent manifest error.
Shares of Common  Stock  owned by or held for the  account of the Company or any
majority-owned subsidiary shall not be deemed outstanding for the purpose of any
such computation.

     (e) No  adjustment  in  the  Exercise  Price  shall  be  required  if  such
adjustment is less than $.05; provided,  however,  that any adjustments which by
reason of this  Section 5 are not  required to be made shall be carried  forward
and taken into account in any subsequent adjustment. All calculations under this
Section 5 shall be made to the nearest cent or to the nearest  one-thousandth of
a share, as the case may be.

     (f) In any case in which this Section 5 shall require that an adjustment in
the Exercise Price be made effective as of a record date for a specified  event,
the Company may elect to defer,  until the occurrence of such event,  issuing to
the Holder,  if the Holder  exercised  this Warrant after such record date,  the
shares of Common Stock,  if any,  issuable upon such exercise over and above the
shares of Common Stock, if any,  issuable upon such exercise on the basis of the
Exercise Price in effect prior to such adjustment;  provided,  however, that the
Company shall deliver to the Holder a due bill or other  appropriate  instrument
evidencing  the  Holder's  right to  receive  such  additional  shares  upon the
occurrence of the event requiring such adjustment

     (g)  Upon  each  adjustment  of  the  Exercise  Price  as a  result  of the
calculations  made in Sections  5(b),  5(c) or 5(d) hereof,  this Warrant  shall
thereafter evidence the right to purchase,  at the adjusted Exercise Price, that
number of shares (calculated to the nearest thousandth) obtained by dividing (A)
the  product  obtained  by  multiplying  the number of shares  purchasable  upon
exercise  of this  Warrant  prior to  adjustment  of the number of shares by the
Exercise  Price in effect prior to adjustment  of the Exercise  Price by (B) the
Exercise Price in effect after such adjustment of the Exercise Price.

     (h) Whenever  there shall be an  adjustment  as provided in this Section 5,
the Company shall promptly cause written notice thereof to be sent by registered
mail,  postage prepaid,  to the Holder, at its address as it shall appear in the
Warrant Register,  which notice shall be accompanied by an officer's certificate
setting forth the number of Warrant Shares purchasable upon the exercise of this
Warrant and the Exercise  Price after such  adjustment and setting forth a brief
statement of the facts requiring such  adjustment and the  computation  thereof,
which officer's  certificate shall be conclusive  evidence of the correctness of
any such adjustment absent manifest error.

     6. (a) In case of any  consolidation  with or merger of the Company with or
into  another  corporation  (other than a merger or  consolidation  in which the
Company is the  surviving or  continuing  corporation),  or in case of any sale,
lease,  or conveyance to another  corporation  of


                                       6
<PAGE>

the  property  and  assets  of any  nature  of the  Company  as an  entirety  or
substantially   as  an  entirety,   such  successor,   leasing,   or  purchasing
corporation,  as the case may be, shall (i) execute with the Holder an agreement
providing  that the Holder  shall  have the right  thereafter  to  receive  upon
exercise of this Warrant solely the kind and amount of shares of stock and other
securities,  property,  cash, or any  combination  thereof  receivable upon such
consolidation,  merger,  sale, lease, or conveyance by a holder of the number of
shares  of Common  Stock  for which  this  Warrant;  might  have been  exercised
immediately prior to such consolidation,  merger, sale, lease, or conveyance and
(ii) make effective  provision in its certificate of incorporation or otherwise,
if  necessary,  to effect  such  agreement.  Such  agreement  shall  provide for
adjustments   which  shall  be  as  nearly  equivalent  as  practicable  to  the
adjustments in Section 5.

     (b) In case of any reclassification or change of the shares of Common Stock
issuable upon exercise of this Warrant (other than a change in par value or from
no par  value to a  specified  par  value,  or as a result of a  subdivision  or
combination,  but including any change in the shares into two or more classes or
series  of  shares),  or in case  of any  consolidation  or  merger  of  another
corporation into the Company in which the Company is the continuing  corporation
and in which there is a  reclassification  or change  (including a change to the
right to receive  cash or other  property)  of the shares of Common Stock (other
than a change in par value, or from no par value to a specified par value, or as
a result of a subdivision or combination, but including any change in the shares
into two or more  classes or series of shares),  the Holder shall have the right
thereafter to receive upon  exercise of this Warrant  solely the kind and amount
of shares of stock and other  securities,  property,  cash,  or any  combination
thereof receivable upon such reclassification,  change, consolidation, or merger
by a holder of the number of shares of Common Stock for which this Warrant might
have  been  exercised  immediately  prior  to  such  reclassification,   change,
consolidation,  or merger.  Thereafter,  appropriate provision shall be made for
adjustments   which  shall  be  as  nearly  equivalent  as  practicable  to  the
adjustments in Section 5.

     (c) The  above  provisions  of this  Section  6 shall  similarly  apply  to
successive  reclassifications  and  changes  of shares  of  Common  Stock and to
successive consolidations, mergers, sales, leases, or conveyances.

     7. In case at any time the Company shall propose

          to pay any dividend or make any distribution on shares of Common Stock
     in shares  of  Common  Stock or make any  other  distribution  (other  than
     regularly  scheduled cash  dividends  which are not in a greater amount per
     share than the most  recent  such cash  dividend)  to all holders of Common
     Stock; or

          to issue any rights,  warrants,  or other securities to all holders of
     Common Stock  entitling  them to purchase any  additional  shares of Common
     Stock or any other rights, warrants, or other securities; or



                                       7
<PAGE>

          to effect  any  reclassification  or change of  outstanding  shares of
     Common Stock, or any consolidation,  merger,  sale, lease, or conveyance of
     property, described in Section 6; or

          to effect any liquidation,  dissolution, or winding-up of the Company;
     or

          to take any  other  action  which  would  cause an  adjustment  to the
     Exercise Price;

then,  and in any one or more of such  cases,  the  Company  shall give  written
notice  thereof,  by  registered  mail,  postage  prepaid,  to the Holder at the
Holder's address as it shall appear in the Warrant Register,  mailed at least 15
days prior to (i) the date as of which the holders of record of shares of Common
Stock to be  entitled  to  receive  any  such  dividend,  distribution,  rights,
warrants,  or other securities are to be determined,  (ii) the date on which any
such   reclassification,   change  of   outstanding   shares  of  Common  Stock,
consolidation,   merger,  sale,  lease,  conveyance  of  property,  liquidation,
dissolution,  or winding-up is expected to become effective,  and the date as of
which it is expected  that  holders of record of shares of Common Stock shall be
entitled to exchange  their shares for  securities  or other  property,  if any,
deliverable   upon  such   reclassification,   change  of  outstanding   shares,
consolidation,   merger,  sale,  lease,  conveyance  of  property,  liquidation,
dissolution, or winding-up, or (iii) the date of such action which would require
an adjustment to the Exercise Price.

     8. (a) If at any time prior to the expiration of the Exercise  Period,  the
Company shall file a registration statement (other than a registration statement
on Form S-4, Form S-8, or any successor  form) with the  Securities and Exchange
Commission (the "Commission")  while any Registrable  Securities (as hereinafter
defined)  are  outstanding,  the Company  shall give all the then holders of any
Registrable  Securities (the "Eligible  Holders") at least 30 days prior written
notice  of the  filing  of such  registration  statement.  If  requested  by any
Eligible Holder in writing within 20 days after receipt of any such notice,  the
Company  shall,  at  the  Company's  sole  expense  (other  than  the  fees  and
disbursements   of  counsel  for  the  Eligible  Holders  and  the  underwriting
discounts,  if any, payable in respect of the Registrable Securities sold by any
Eligible Holder),  register or qualify all or, at each Eligible Holder's option,
any portion of the Registrable Securities of any Eligible Holders who shall have
made such request,  concurrently with the registration of such other securities,
all to the  extent  requisite  to permit the  public  offering.  and sale of the
Registrable  Securities  through the  facilities of all  appropriate  securities
exchanges and the over-the-counter market, and will use its best efforts through
its  officers,  directors,  auditors,  and  counsel to cause  such  registration
statement to become  effective as promptly as practicable.  Notwithstanding  the
foregoing,  if the managing  underwriter  of any such offering  shall advise the
Company in writing that, in its opinion, the distribution of all or a portion of
the  Registrable  Securities  requested  to  be  included  in  the  registration
concurrently   with  the  securities  being  registered  by  the  Company  would
materially  adversely  affect the distribution of such securities by the Company
for its  own  account,  then  any  Eligible  Holder  who  shall  have  requested
registration of his or its Registrable  Securities  shall delay the offering and
sale of such  Registrable  Securities (or the portions  thereof so designated by
such managing  underwriter)  for


                                       8
<PAGE>

such  period,  not to exceed  90 days  (the  "Delay  Period"),  as the  managing
underwriter  shall request,  provided that no such delay shall be required as to
any Registrable Securities if any securities of the Company are included in such
registration  statement  and  eligible  for sale during the Delay Period for the
account of any person other than the Company and any Eligible  Holder unless the
securities included in such registration  statement and eligible for sale during
the Delay  Period for such other  person shall have been reduced pro rata to the
reduction of the Registrable  Securities which were requested to be included and
eligible for sale during the Delay Period in such registration.  As used herein'
"Registrable  Securities"  shall mean the Warrants and the Warrant Shares which,
in each case, have not been previously sold pursuant to a registration statement
or Rule 144 promulgated under the Act.

     (b) If, at any time prior to the  expiration  of the Exercise  Period,  the
Company  shall  receive a written  request,  from  Eligible  Holders  who in the
aggregate  own (or upon exercise of all Warrants  then  outstanding  or issuable
would own) 50% of the total number of shares of Common  Stock then  included (or
upon such  exercises  would be  included)  in the  Registrable  Securities  (the
"Majority  Holders"),  to register  the sale of all or part of such  Registrable
Securities, the Company shall, as promptly as practicable, prepare and file with
the Commission a registration statement sufficient to permit the public offering
and sale of the Registrable Securities through the facilities of all appropriate
securities  exchanges  and the  over-the-counter  market,  and will use its best
efforts  through its officers,  directors,  auditors,  and counsel to cause such
registration statement to become effective as promptly as practicable; provided,
however,  that the Company shall only be obligated to file one such registration
statement for which all expenses  incurred in connection with such  registration
(other than the fees and  disbursements  of counsel for the Eligible Holders and
underwriting discounts, if any, payable in respect of the Registrable Securities
sold by the Eligible  Holders) shall be borne by the Company.  The Company shall
not be obligated to effect any  registration of its securities  pursuant to this
Section  8(b)  within  six  months  after  the  effective  date  of  a  previous
registration  statement  prepared and filed in accordance  with Sections 8(a) or
8(b).  Within three business days after  receiving any request  contemplated  by
this  Section  8(b),  the  Company  shall give  written  notice to all the other
Eligible Holders, advising each of them that the Company is proceeding with such
registration  and  offering  to include  therein  all or any portion of any such
other  Eligible  Holder's  Registrable  Securities,  provided  that the  Company
receives a written  request to do so from such  Eligible  Holder  within 30 days
after receipt by him or it of the Company's notice.

     (c) In the  event of a  registration  pursuant  to the  provisions  of this
Section  8, the  Company  shall use its best  efforts  to cause the  Registrable
Securities  so  registered  to be  registered  or  qualified  for sale under the
securities or blue sky laws of such jurisdictions as the Eligible Holder or such
holders may reasonably request; provided, however, that the Company shall not be
required to qualify to do business in any state by reason of this  Section  8(c)
in which it is not otherwise required to qualify to do business.

     (d) The Company shall keep  effective  any  registration  or  qualification
contemplated  by this Section 8 and shall from time to time amend or  supplement
each  applicable   registration   statement,   preliminary   prospectus,   final
prospectus,  application, document, and


                                       9
<PAGE>

communication  for such  period  of time as  shall be  required  to  permit  the
Eligible  Holders to complete the offer and sale of the  Registrable  Securities
covered  thereby.  The  Company  shall in no event be  required to keep any such
registration  or  qualification  in effect for a period in excess of nine months
from the  date on  which  the  Eligible  Holders  are  first  free to sell  such
Registrable Securities;  provided,  however, that, if the Company is required to
keep any such registration or qualification in effect with respect to securities
other than the Registrable Securities beyond such period, the Company shall keep
such  registration or  qualification  in effect as it relates to the Registrable
Securities  for so long as such  registration  or  qualification  remains  or is
required to remain in effect in respect of such other securities.

     (e) In the  event of a  registration  pursuant  to the  provisions  of this
Section 8, the  Company  shall  furnish to each  Eligible  Holder such number of
copies  of the  registration  statement  and of each  amendment  and  supplement
thereto (in each case, including all exhibits), such reasonable number of copies
of each prospectus contained in such registration  statement and each supplement
or amendment thereto (including each preliminary prospectus), all of which shall
conform to the requirements of the Act and the rules and regulations thereunder,
and such other  documents,  as any  Eligible  Holder may  reasonably  request to
facilitate  the  disposition  of the  Registrable  Securities  included  in such
registration.

     (f) In the  event of a  registration  pursuant  to the  provisions  of this
Section 8, the Company  shall furnish each  Eligible  Holder of any  Registrable
Securities so registered with an opinion of its counsel  (reasonably  acceptable
to the Eligible  Holders) to the effect that (i) the registration  statement has
become effective under the Act and no order suspending the  effectiveness of the
registration  statement,  preventing or suspending  the use of the  registration
statement, any preliminary prospectus, any final prospectus, or any amendment or
supplement  thereto has been issued, nor has the Commission or any securities or
blue sky authority of any jurisdiction instituted or threatened to institute any
proceedings with respect to such an order,  (ii) the registration  statement and
each prospectus forming a part thereof (including each preliminary  prospectus),
and any  amendment or supplement  thereto,  complies as to form with the Act and
the rules and regulations thereunder, and (iii) such counsel has no knowledge of
any  material  misstatement  or omission in such  registration  statement or any
prospectus,  as  amended  or  supplemented.  Such  opinion  shall also state the
jurisdictions  in which  the  Registrable  Securities  have been  registered  or
qualified for sale pursuant to the provisions of Section 8(c).

     (g) In the  event  of a  registration  pursuant  to the  provision  of this
Section 8, the  Company  shall  enter  into a  cross-indemnity  agreement  and a
contribution agreement,  each in customary form, with each underwriter,  if any,
and, if requested,  enter into an underwriting agreement containing conventional
representations,  warranties,  allocation  of expenses,  and  customary  closing
conditions,  including, but not limited to, opinions of counsel and accountants'
cold  comfort  letters,  with  any  underwriter  who  acquires  any  Registrable
Securities.

     (h) In the  event of a  registration  pursuant  to the  provisions  of this
Section 8:



                                       10
<PAGE>

          Each  Eligible  Holder  shall  furnish to the Company in writing  such
     appropriate information (relating to such Eligible Holder and the intention
     of such Eligible Holder as to proposed methods of sale or other disposition
     of their shares of Common Stock) and the identity of and compensation to be
     paid to any proposed underwriters to be employed in connection therewith as
     the Company,  any  underwriter,  or the Commission or any other  regulatory
     authority may request;

          the Eligible  Holders shall enter into the usual and customary form of
     underwriting  agreement  agreed to by the Company and any underwriter  with
     respect to any such offering, if required,  and such underwriting agreement
     shall contain the customary  rights of indemnity  between the Company,  the
     underwriters, and such Eligible Holders;

          each Eligible Holder shall agree that he shall execute, deliver and/or
     file with or supply the Company,  any  underwriters,  the Commission and/or
     any  state or  other  regulatory  authority  such  information,  documents,
     representations,  undertakings and/or agreements necessary to carry out the
     provisions of the registration covenants contained in this Section 8 and/or
     to effect  the  registration  or  qualification  of his or its  Registrable
     Securities  under the Act  and/or  any of the laws and  regulations  of any
     state of governmental instrumentality;

          the Company's  obligation to include any  Registrable  Securities in a
     registration  statement  shall be subject to the written  agreement of each
     holder thereof to offer such  securities in the same manner and on the same
     terms and  conditions  as the other  securities of the same class are being
     offered  pursuant to the registration  statement,  if such shares are being
     underwritten;

          in the event that all the Registrable Securities have not been sold on
     or prior to the  expiration of the period  specified in Section 8(d) above,
     the Company may  de-register by  post-effective  amendment any  Registrable
     Securities covered by the registration statement,  but not sold on or prior
     to such  date.  The  Company  agrees  that it will  notify  each  holder of
     Registrable   Securities  of  the  filing  and   effective   date  of  such
     post-effective amendment; and

          each Eligible Holder agrees that upon notification by the Company that
     the prospectus in respect to any public offering  covered by the provisions
     hereof is in need of revision,  such Eligible Holder shall immediately upon
     receipt of such  notification  (x) cease to offer or sell any securities of
     the Company which must be  accompanied by such  prospectus,  (y) return all
     such prospectuses in such Eligible  Holder's hands to the Company,  and (z)
     not offer or sell any  securities of the Company until such Holder has been
     provided with a current  prospectus and the Company has given such Eligible
     Holder  notification  permitting  such Eligible Holder to resume offers and
     sales.



                                       11

     (i) The Company agrees that until all the Registrable  Securities have been
sold under a  registration  statement  or pursuant to Rule 144 under the Act, it
shall  keep  current  in filing  all  reports,  statements  and other  materials
required to be filed with the  Commission to permit  holders of the  Registrable
Securities to sell such securities under Rule 144.

     (j) Except for rights granted to holders of the Warrants,  the Company will
not, without the written consent of the Majority  Holders,  grant to any persons
the right to request the  Company to register  any  securities  of the  Company,
provided that the Company may grant such registration rights to other persons so
long as such rights are  subordinate or pari passu to the rights of the Eligible
Holders.

     9. (a) Subject to the  conditions  set forth below,  the Company  agrees to
indemnify  and hold  harmless each  Eligible  Holder,  its officers,  directors,
partners,  employees,  agents and counsel, and each person, if any, who controls
any such person  within the meaning of Section 15 of the Act or Section 20(a) of
the Securities  Exchange Act of 1934, as amended (the "Exchange Act"),  from and
against  any and  all  loss,  liability,  charge,  claim,  damage,  and  expense
whatsoever (which shall include,  for all purposes of this Section 9, but not be
limited  to,  attorneys'  fees  and any and all  reasonable  expense  whatsoever
incurred in  investigating,  preparing,  or  defending  against any  litigation,
commenced or threatened,  or any claim whatsoever,  and any and all amounts paid
in settlement of any claim or litigation), as and when incurred, arising out of,
based upon, or in connection  with:  (i) any untrue  statement or alleged untrue
statement  of a  material  fact  contained  (A) in any  registration  statement,
preliminary  prospectus,  or final  prospectus (as from time to time amended and
supplemented),  or any amendment or supplement thereto,  relating to the sale of
any of the Registrable  Securities,  or (B) in any application or other document
or  communication  (in this  Section 9  collectively  called  an  "application")
executed  by or on behalf  of the  Company  or based  upon  written  information
furnished by or on behalf of the Company filed in any  jurisdiction  in order to
register or qualify any of the  Registrable  Securities  under the securities or
blue sky laws thereof or filed with the Commission or any  securities  exchange;
or (ii) any omission or alleged omission to state a material fact required to be
stated in any  document  referenced  in clause (A) or (B) above or  necessary to
make the statements  therein not  misleading,  unless such statement or omission
was made in reliance upon and in conformity with written  information  furnished
to the  Company  with  respect to such  Eligible  Holder by or on behalf of such
person  expressly  for  inclusion  in any  registration  statement,  preliminary
prospectus,  or final prospectus,  or any amendment or supplement thereto, or in
any application,  as the case may be; or (iii) any breach of any representation,
warranty,  covenant,  or agreement of the Company contained in this Warrant. The
foregoing  agreement  to  indemnify  shall be in addition to any  liability  the
Company may otherwise have, including liabilities arising under this Warrant.

     If  any  action  is  brought  against  any  Eligible  Holder  or any of its
officers, directors, partners, employees, agents, or counsel, or any controlling
persons of such person (an  "indemnified  party") in respect of which  indemnity
may be sought  against the Company  pursuant to the  foregoing  paragraph,  such
indemnified party or parties shall promptly notify the Company in writing of the
institution  of such action (but the failure so to notify  shall not relieve the

                                       12
<PAGE>

Company from any liability  other than pursuant to this Section 9(a),  except to
the extent it may have been prejudiced in any material  respect by such failure)
and the Company shall promptly assume the defense of such action,  including the
employment of counsel  (reasonably  satisfactory  to such  indemnified  party or
parties) and payment of expenses.  Such indemnified  party or parties shall have
the right to employ its or their own counsel in any such case,  but the fees and
expenses of such counsel  shall be at the expense of such  indemnified  party or
parties  unless the  employment  of such counsel  shall have been  authorized in
writing by the  Company in  connection  with the  defense of such  action or the
Company shall not have promptly employed counsel reasonably satisfactory to such
indemnified  party or parties to have  charge of the  defense of such  action or
such indemnified party or parties shall have reasonably concluded that there may
be one or more legal  defenses  available to it or them or to other  indemnified
parties  which  are  different  from or  additional  to those  available  to the
Company,  in any of which  events such fees and  expenses  shall be borne by the
Company and the  Company  shall not have the right to direct the defense of such
action on behalf of the indemnified  party or parties.  Anything in this Section
10 to the  contrary  notwithstanding,  the  Company  shall not be liable for any
settlement  of any such claim or action  effected  without its written  consent,
which shall not be  unreasonably  withheld.  The Company shall not,  without the
prior  written  consent  of  each  indemnified  party  that is not  released  as
described in this sentence, settle or compromise any action, or permit a default
or  consent to the entry of  judgment  in or  otherwise  seek to  terminate  any
pending  or  threatened  action,  in respect  of which  indemnity  may be sought
hereunder (whether or not any indemnified party is a party thereto), unless such
settlement,  compromise,  consent,  or  termination  includes  an  unconditional
release of each indemnified  party from all liability in respect of such action.
The Company agrees promptly to notify the Eligible  Holders of the  commencement
of any litigation or  proceedings  against the Company or any of its officers or
directors  in  connection  with the sale of any  Registrable  Securities  or any
preliminary  prospectus,  prospectus,  registration  statement,  or amendment or
supplement thereto,  or any application  relating to any sale of any Registrable
Securities.

     (b) The Holder  agrees to indemnify  and hold  harmless  the Company,  each
director of the  Company,  each officer of the Company who shall have signed any
registration  statement covering Registrable Securities held by the Holder, each
other person,  if any, who controls the Company within the meaning of Section 15
of the Act or Section  20(a) of the Exchange  Act,  and its or their  respective
counsel,  to the same extent as the foregoing  indemnity from the Company to the
Holder in Section 9(a),  but only with respect to  statements  or omissions,  if
any,  made in any  registration  statement,  preliminary  prospectus,  or  final
prospectus (as from time to time amended and supplemented),  or any amendment or
supplement  thereto,  or in any application,  in reliance upon and in conformity
with written information  furnished to the Company with respect to the Holder by
or on behalf of the Holder  expressly  for  inclusion  in any such  registration
statement,  preliminary  prospectus,  or final  prospectus,  or any amendment or
supplement  thereto,  or in any  application,  as the case may be. If any action
shall be brought against the Company or any other person so indemnified based on
any such registration statement, preliminary prospectus, or final prospectus, or
any amendment or supplement  thereto,  or in any application,  and in respect of
which  indemnity may be sought against the Holder pursuant to this Section 9(b),
the  Holder  shall have the rights  and  duties  given to the  Company,


                                       13
<PAGE>

and the Company and each other person so  indemnified  shall have the rights and
duties given to the indemnified parties, by the provisions of Section 9(a).

     (c) To provide for just and equitable  contribution,  if (i) an indemnified
party  makes  a claim  for  indemnification  pursuant  to  Section  9(a) or 9(b)
(subject  to the  limitations  thereof)  but it is  found  in a  final  judicial
determination,  not subject to further appeal, that such indemnification may not
be enforced in such case,  even though this  Agreement  expressly  provides  for
indemnification  in such case, or (ii) any  indemnified  or  indemnifying  party
seeks  contribution  under the Act,  the  Exchange  Act or  otherwise,  then the
Company (including for this purpose any contribution made by or on behalf of any
director  of the  Company,  any  officer  of the  Company  who  signed  any such
registration statement,  any controlling person of the Company, and its or their
respective counsel),  as one entity, and the Eligible Holders of the Registrable
Securities  included in such  registration in the aggregate  (including for this
purpose any contribution by or on behalf of an indemnified  party),  as a second
entity,  shall  contribute  to the losses,  liabilities,  claims,  damages,  and
expenses  whatsoever  to  which  any of them  may be  subject,  on the  basis of
relevant equitable  considerations such as the relative fault of the Company and
such  Eligible  Holders in  connection  with the facts  which  resulted  in such
losses,  liabilities,  claims, damages, and expenses. The relative fault, in the
case of an untrue  statement,  alleged untrue  statement,  omission,  or alleged
omission,  shall be determined by, among other things,  whether such  statement,
alleged statement, omission, or alleged omission relates to information supplied
by the Company or by such Eligible  Holders,  and the parties'  relative intent,
knowledge,  access to  information,  and  opportunity to correct or prevent such
statement, alleged statement, omission, or alleged omission. The Company and the
Holder  agree  that  it  would  be  unjust  and  inequitable  if the  respective
obligations  of the  Company and the  Eligible  Holders  for  contribution  were
determined  by pro  rata  or per  capita  allocation  of the  aggregate  losses,
liabilities,  claims,  damages,  and expenses  (even if the Holder and the other
indemnified parties were treated as one entity for such purpose) or by any other
method of allocation that does not reflect the equitable considerations referred
to in this Section 9(c). In no case shall any Eligible Holder be responsible for
a portion of the  contribution  obligation  imposed on all  Eligible  Holders in
excess of its pro rata share based on the number of shares of Common Stock owned
(or which would be owned upon exercise of the Registrable  Securities) by it and
included  in such  registration  as  compared  to the number of shares of Common
Stock  owned  (or  which  would  be  owned  upon  exercise  of  the  Registrable
Securities) by all Eligible Holders and included in such registration. No person
guilty of a fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution  from any person who is not guilty of
such  fraudulent  misrepresentation.  For  purposes of this Section  9(c),  each
person,  if any, who controls any Eligible  Holder within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act and each  officer,  director,
partner,  employee,  agent,  and counsel of each such Eligible Holder or control
person shall have the same rights to  contribution  as such  Eligible  Holder or
control  person and each person,  if any,  who  controls the Company  within the
meaning  of Section 15 of the Act or Section  20(a) of the  Exchange  Act,  each
officer of the Company who shall have  signed any such  registration  statement,
each director of the Company, and its or their respective counsel shall have the
same  rights  to  contribution  as the  Company,  subject  in  each  case to the
provisions of this Section  9(c).  Anything in this Section 9(c) to the contrary

                                       14
<PAGE>

notwithstanding,  no party shall be liable for contribution  with respect to the
settlement of any claim or action  effected  without its written  consent.  This
Section 9(c) is intended to supersede any right to  contribution  under the Act,
the Exchange Act or otherwise.

     10. The  issuance of any shares or other  securities  upon the  exercise of
this Warrant, and the delivery of certificates or other instruments representing
such shares or other securities,  shall be made without charge to the Holder for
any tax or other  charge in respect of such  issuance.  The  Company  shall not,
however,  be  required  to pay any tax which may be  payable  in  respect of any
transfer  involved in the issue and delivery of any  certificate in a name other
than  that of the  Holder  and the  Company  shall not be  required  to issue or
deliver any such certificate  unless and until the person or persons  requesting
the issue thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

     11. Certificates  evidencing the Warrant Shares issued upon exercise of the
Warrants shall bear the following legend:

         "THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN REGISTERED
         UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED.  SUCH SHARES MAY NOT BE
         OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE  REGISTRATION STATEMENT
         UNDER SUCH ACT, OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT."

     12.  Upon  receipt of  evidence  satisfactory  to the  Company of the loss,
theft,  destruction,  or  mutilation  of any Warrant (and upon  surrender of any
Warrant  if  mutilated),  and upon  reimbursement  of the  Company's  reasonable
incidental expenses, the Company shall execute and deliver to the Holder thereof
a new Warrant of like date, tenor, and denomination.

     13. The  Holder of any  Warrant  shall not have,  solely on account of such
status, any rights of a stockholder of the Company,  either at law or in equity,
or to any notice of meetings of stockholders or of any other  proceedings of the
Company, except as provided in this Warrant.

     14. Any notice or other  communication  required or  permitted  to be given
hereunder  shall be in writing  and shall be mailed by  certified  mail,  return
receipt requested or sent by Federal Express, Express Mail, or similar overnight
delivery or courier  service or delivered (in person or by telecopy,  telex,  or
similar telecommunications equipment) against receipt to the party to whom it is
to be given, if sent to the Company,  at: 150 East 58th Street,  Suite 3400, New
York, New York 10155, Attention: The Chairman or the Chief Executive Officer; or
if sent to the Holder, at the Holder's address as it shall appear on the Warrant
Register;  or to such other address as the party shall have furnished in writing
in  accordance  with the  provisions  of this  Section  14.  Any notice or other
communication  given by  certified  mail  shall be  deemed  given at the


                                       15
<PAGE>

time of  certification  thereof,  except for a notice changing a party's address
which will be deemed given at the time of receipt  thereof.  Any notice given by
other means  permitted  by this  Section 14 shall be deemed given at the time of
receipt thereof.

     15. This Warrant shall be binding upon the Company and its  successors  and
assigns  and shall  inure to the  benefit of the Holder and its  successors  and
assigns.

     16. This  Warrant  shall be construed  in  accordance  with the laws of the
State of New York applicable to contracts made and performed  within such State,
without regard to principles of conflicts of law.

     17. The Company  irrevocably  consents to the jurisdiction of the courts of
the  State  of New  York  and of any  federal  court  located  in such  State in
connection  with any action or  proceeding  arising  out of or  relating to this
Warrant, any document or instrument delivered pursuant to, in connection with or
simultaneously  with  this  Warrant,  or a breach  of this  Warrant  or any such
document or  instrument.  In any such action or  proceeding,  the Company waives
personal service of any summons, complaint or other process.

     AGREEMENT made as of the 15th day of December (the "Date of Grant") between
Commodore  Applied  Technologies,  Inc.,  a  Delaware  corporation  (hereinafter
referred  to as the  "Company"),  and  Bentley J. Blum,  residing at 150 E. 58th
Street,  Suite  3400,  New  York,  NY,  10155  (hereinafter  referred  to as the
"Director").


                              W I T N E S S E T H:
                               - - - - - - - - - -

     WHEREAS, the Company desires, in accordance with its 1998 Stock Option Plan
(the "Plan"),  to provide the Director  with an  opportunity  to acquire  Common
Stock,  $0.001 par value  (hereinafter  referred to as "Common  Stock"),  of the
Company on favorable terms and thereby increase his proprietary  interest in the
continued progress and success of the business of the Company;

     NOW,  THEREFORE,  in  consideration  of the premises,  the mutual covenants
herein set forth and other good and valuable consideration,  the Company and the
Director hereby agree as follows:

     1.  Confirmation  of Grant of Option.  Pursuant to a  determination  by the
Board of Directors of the Company, the Company, subject to the terms of the Plan
and this  Agreement,  hereby  grants to the  Director  as a matter  of  separate
inducement and agreement,  and in addition to and not in lieu of salary or other
compensation for services, the right to purchase (hereinafter referred to as the
"Option") an aggregate of 70,000 shares of Common  Stock,  subject to adjustment
as provided in the Plan (such shares, as adjusted, hereinafter being referred to
as the  "Shares").  The Option is not intended to qualify as an incentive  stock
option under  Section 422 of the Internal  Revenue Code of 1986, as amended (the
"Code").

     2. Purchase Price.  The purchase price of shares of Common Stock covered by
the Option will be $0.4375 per share,  subject to  adjustment as provided in the
Plan.

     3. Exercise of Option.  (a) In accordance with the provisions of Section 21
hereof, by his execution and delivery hereof,  the Director agrees to cancel all
prior options to acquire  shares of Common Stock ("Prior  Options").  The Option
shall be  exercisable  on the terms and  conditions  set forth and in accordance
with the vesting schedule  applicable to the Prior Options, as though the Option
had been granted at the time of the grant of the Prior Options.

     (b) The Option may be exercised  pursuant to the provisions of this Section
3, by notice and payment to the Company as provided in Sections 9 and 14 hereof.

     4. Term of  Option.  The term of the  Option  shall be a period of ten (10)
years from the Date of Grant,  subject to earlier termination or cancellation as
provided in this Agreement.


<PAGE>

This Option,  to the extent  unexercised,  shall  expire on the day  immediately
prior to the tenth (10th)  anniversary  of the Date of Grant.  The holder of the
Option  shall  not have  any  rights  to  dividends  or any  other  rights  of a
stockholder  with  respect to any shares of Common  Stock  subject to the Option
until such shares shall have been issued to him (as evidenced by the appropriate
entry on the books of the  Company or a duly  authorized  transfer  agent of the
Company)  provided that the date of issuance  shall not be earlier than the date
this Option is exercised and payment of the full purchase price of the shares of
Common  Stock (with  respect to which this Option is  exercised)  is made to the
Company.

     5.  Non-transferability  of  Option.  The  Option  shall  not be  assigned,
transferred or otherwise disposed of, or pledged or hypothecated in any way, and
shall not be subject to execution, attachment or other process, except as may be
provided in the Plan. Any assignment,  transfer, pledge,  hypothecation or other
disposition of the Option  attempted  contrary to the provisions of the Plan, or
any levy of execution,  attachment or other process  attempted  upon the Option,
will be null  and  void  and  without  effect.  Any  attempt  to make  any  such
assignment,  transfer, pledge,  hypothecation or other disposition of the Option
will cause the Option to terminate  immediately  upon the  happening of any such
event;  provided,  however,  that any such  termination  of the Option under the
foregoing provisions of this Section 5 will not prejudice any rights or remedies
which the Company or any Parent or Subsidiary  may have under this  Agreement or
otherwise.

     6. Exercise Upon  Termination of Service as a Director.  If the Director at
any time  ceases to be a Director  of the  Company by reason of his removal as a
Director,  the Option  shall,  at the time of such  removal,  terminate  and the
Director shall forfeit all rights hereunder.  If, however,  the Director for any
other reason (other than Disability or death) ceases to be such an Director, the
Option may,  subject to the provisions of Section 5 hereof,  be exercised by the
Director to the same extent the Director  would have been entitled under Section
3 hereof to exercise the Option immediately prior to such the termination of his
services as a Director,  at any time within 30 days after such  termination,  at
the end of which  period the  Option,  to the extent not then  exercised,  shall
terminate  and the  Director  shall  forfeit all rights  hereunder,  even if the
Director subsequently serves as a Director of the Company. In no event, however,
may the Option be exercised after the expiration of the term provided in Section
4 hereof.

     7. Exercise Upon Death or Disability.  (a) If the Director dies while he is
a Director of the Company,  the Option may, subject to the provisions of Section
5 hereof,  be exercised  with respect to all or any part of the shares of Common
Stock as to which the deceased Director had not exercised the Option at the time
of his death  (regardless  of whether the option was fully  exercisable  at such
time) by the estate of the Director (or by the person or persons who acquire the
right to exercise the Option by written designation of the Director) at any time
within 90 days after the death of the  Director,  at the end of which period the
Option,  to the extent not then  exercised,  shall  terminate  and the estate or
other  beneficiaries shall forfeit all rights hereunder.  In no event,  however,
may the Option be exercised after the expiration of the term provided in Section
4 hereof.


<PAGE>

     8.  Registration.  At the time of  issuance,  the  shares of  Common  Stock
subject hereto and issuable upon the exercise hereof may not be registered under
the  Securities  Act of 1933,  as amended,  and, if required upon the request of
counsel  to the  Company,  the  Director  will give a  representation  as to his
investment  intent with  respect to such shares  prior to their  issuance as set
forth in Section 8 hereof.  The  Company  may  register  or  qualify  the shares
covered  by the Option  for sale  pursuant  to the  Securities  Act of 1933,  as
amended,  at any time prior to or after the  exercise in whole or in part of the
Option.

     9. Method of Exercise of Option. (a) Subject to the terms and conditions of
this  Agreement,  the Option  shall be  exercisable  by notice in the manner set
forth in  Exhibit A hereto  (the  "Notice")  and  provision  for  payment to the
Company in accordance  with the procedure  prescribed  herein.  Each such Notice
shall:

          (i) state the election to exercise the Option and the number of Shares
     with respect to which it is being exercised;

          (ii) contain a representation  and agreement as to investment  intent,
     if required by counsel to the Company  with  respect to such  Shares,  in a
     form satisfactory to counsel to the Company;

          (iii) be signed by the  Director or the person or persons  entitled to
     exercise the Option and, if the Option is being  exercised by any person or
     persons other than the Director,  be accompanied by proof,  satisfactory to
     counsel to the  Company,  of the right of such  other  person or persons to
     exercise the Option;

          (iv)  include  payment  of the full  purchase  price for the shares of
     Common Stock to be purchased pursuant to such exercise of the Option; and

          (v) be received by the Company on or before the date of the expiration
     of this Option. In the event the date of expiration of this Option falls on
     a day which is not a regular business day at the Company's executive office
     in New York,  New York then such  written  Notice  must be received at such
     office on or before  the last  regular  business  day prior to such date of
     expiration.

     (b) Payment of the purchase price of any shares of Common Stock, in respect
of which the Option  shall be  exercised,  shall be made by the Director or such
person or persons at the place  specified  by the Company on the date the Notice
is received by the Company (i) by  delivering to the Company a certified or bank
cashier's check payable to the order of the Company, (ii) if consented to by the
Company in writing, by delivering to the Company properly endorsed  certificates
of shares of Common Stock (or certificates  accompanied by an appropriate  stock
power) with  signature  guaranties by a bank or trust  company,  (iii) by having
withheld from the total number of shares of Common Stock to be acquired upon the
exercise of this Option a specified number of such shares of Common Stock,  (iv)
by any form of "cashless"  exercise or (v) by any  combination of the foregoing.
For purposes of the immediately  preceding sentence, an

<PAGE>

exercise effected by the tender of the Common Stock (or deemed to be effected by
the tender of Common Stock) may be  consummated  only with Common Stock (i) held
by the Director for six (6) months or (ii)  acquired by the Director  other than
under the Plan (or a similar plan maintained by the Company).

     (c) The Option shall be deemed to have been  exercised  with respect to any
particular  shares of Common Stock if, and only if, the preceding  provisions of
this Section 9 and the  provisions of Section 10 hereof shall have been complied
with,  in which event the Option  shall be deemed to have been  exercised on the
date the Notice and related  payment were  received by the Company.  Anything in
this Agreement to the contrary notwithstanding, any Notice given pursuant to the
provisions  of this  Section  9 shall  be void  and of no  effect  if all of the
preceding  provisions  of this Section 9 and the  provisions of Section 10 shall
not have been complied with.

     (d) The certificate or certificates  for shares of Common Stock as to which
the Option shall be exercised will be registered in the name of the Director (or
in the name of the  Director's  estate  or other  beneficiary  if the  Option is
exercised  after the  Director's  death),  or if the Option is  exercised by the
Director  and if the Director so requests in the notice  exercising  the Option,
will be registered in the name of the Director and another person jointly,  with
right of survivorship  and will be delivered as soon as practical after the date
the  Notice is  received  by the  Company  (accompanied  by full  payment of the
exercise  price),  but only upon  compliance  with all of the provisions of this
Agreement.

     (e) If the Director fails to accept delivery of and pay for all or any part
of the number of Shares  specified  in such  Notice,  his right to exercise  the
Option with respect to such  undelivered  Shares may be  terminated  in the sole
discretion of the  Committee.  The Option may be exercised  only with respect to
full Shares.

     (f) The Company  shall not be required to issue or deliver any  certificate
or  certificates  for shares of its Common Stock  purchased upon the exercise of
any part of the Option prior to the payment to the Company,  upon its demand, of
any amount requested by the Company for the purpose of satisfying its liability,
if any, to withhold federal,  state or local income or earnings tax or any other
applicable tax or assessment (plus interest or penalties thereon, if any, caused
by a delay in making such  payment)  incurred by reason of the  exercise of this
Option or the transfer of shares  thereupon.  Such payment  shall be made by the
Director in cash or, with the written  consent of the  Company,  by tendering to
the Company  shares of Common Stock equal in value to the amount of the required
withholding.  In the alternative,  the Company may, at its option,  satisfy such
withholding  requirements  by withholding  from the shares of Common Stock to be
delivered  to the  Director  pursuant  to an  exercise of the Option a number of
shares of Common Stock equal in value to the amount of the required withholding.

     10.  Approval of Counsel.  The  exercise of the Option and the issuance and
delivery of shares of Common Stock pursuant thereto shall be subject to approval
by  the  Company's  counsel  of  all  legal  matters  in  connection  therewith,
including,  but  not  limited  to,  compliance  with  the  requirements  of  the
Securities Act of 1933, as amended,  and the Securities

<PAGE>

Exchange Act of 1934, as amended, and the rules and regulations thereunder,  and
the  requirements  of any stock exchange or automated  trading medium upon which
the Common Stock may then be listed or traded.

     11.  Resale of Common Stock.  (a) If so requested by the Company,  upon any
sale or transfer of the Common Stock  purchased  upon exercise of the Option the
Director shall deliver to the Company an opinion of counsel  satisfactory to the
Company to the effect that either (i) the Common Stock to be sold or transferred
has been registered under the Securities Act of 1933, as amended, and that there
is in effect a current  prospectus  meeting the requirements of Section 10(a) of
said Act which is being or will be delivered to the  purchaser or  transferee at
or prior to the time of delivery of the certificates evidencing the Common Stock
to be sold or  transferred,  or (ii) such Common  Stock may then be sold without
violating Section 5 of said Act.

     (b) The Common  Stock  issued upon  exercise  of the Option  shall bear the
following (or similar) legend if required by counsel for the Company:

               THE  SHARES  EVIDENCED  BY  THIS  CERTIFICATE  MAY  NOT BE  SOLD,
               TRANSFERRED,  PLEDGED,  HYPOTHECATED  OR  OTHERWISE  DISPOSED  OF
               UNLESS THEY HAVE FIRST BEEN  REGISTERED  UNDER THE SECURITIES ACT
               OF 1933, AS AMENDED, OR UNLESS, IN THE OPINION OF COUNSEL FOR THE
               COMPANY, SUCH REGISTRATION IS NOT REQUIRED.

     12.  Reservation of Shares.  The Company shall at all times during the term
of the Option  reserve  and keep  available  such number of shares of the Common
Stock as will be sufficient to satisfy the requirements of this Agreement.

     13.  Limitation of Action.  The Director and the Company each  acknowledges
that  every  right of  action  accruing  to him or it,  as the case may be,  and
arising out of or in connection with this Agreement against the Company,  on the
one hand, or against the Director, on the other hand, shall, irrespective of the
place where an action may be brought,  cease and be barred by the  expiration of
three  years from the date of the act or omission in respect of which such right
of action arises.

     14. Notices. Each notice relating to this Agreement shall be in writing and
delivered in person, by recognized overnight carrier or by certified mail to the
proper  address.  All notices to the Company or the Committee shall be addressed
to them at 150 E. 58th Street,  New York, NY 10155-1596,  Attn:  President.  All
notices to the Director  shall be addressed to the Director or such other person
or persons at the Director's  address above  specified.  Anyone to whom a notice
may be given under this  Agreement may designate a new address by notice to that
effect.

     15. Benefits of Agreement. This Agreement shall inure to the benefit of the

<PAGE>

Company,  the Director and their respective  heirs,  executors,  administrators,
personal representatives, successors and assigns.

     16.  Severability.  In the event  that any one or more  provisions  of this
Agreement  shall be deemed to be illegal or  unenforceable,  such  illegality or
unenforceability  shall  not  affect  the  validity  and  enforceability  of the
remaining legal and enforceable  provisions hereof,  which shall be construed as
if such illegal or unenforceable provision or provisions had not been inserted.

     17.  Governing  Law.  This  Agreement  will be  construed  and  governed in
accordance with the laws of the State of Delaware.

     18. Service as a Director.  Nothing  contained in this  Agreement  shall be
construed as (a) a contract of employment  between the Director and the Company,
(b) as a right of the  Director to continue as a Director of the Company  beyond
the term for which he has been  elected,  or (c) as a limitation of the right of
the Company to remove the Director at any time,  in accordance  with  applicable
law and the Company's by-laws.

     19.  Definitions.  Unless otherwise  defined herein,  all capitalized terms
used in this Agreement shall have the same definitions as set forth in the Plan.

     20.  Incorporation  of Terms of Plan.  This Agreement  shall be interpreted
under,  and subject to, all of the terms and  provisions of the Plan,  which are
incorporated herein by reference.

     21.  Cancellation of Prior Option. By executing this Agreement the Director
hereby agrees that effective as of December 15, 1998, of all of his rights under
the  Option(s)  granted to him  pursuant to the Amended and  Restated  Commodore
Applied Technologies, Inc. 1996 Stock Option Plan are hereby cancelled.

     IN WITNESS WHEREOF, the parties have executed this Agreement as of the Date
of Grant set forth above.

                      NON-QUALIFIED STOCK OPTION AGREEMENT

     AGREEMENT  made as of the 15th day of December,  1998 (the "Date of Grant")
between   Commodore   Applied   Technologies,   Inc.,  a  Delaware   corporation
(hereinafter referred to as the "Company"),  and Paul E. Hannesson,  residing at
150 E. 58th Street, Suite 3400, New York, NY, 10155 (hereinafter  referred to as
the "Employee").


                              W I T N E S S E T H:
                               - - - - - - - - - -

     WHEREAS,  the Company  desires,  in connection  with the  employment of the
Employee  and in  accordance  with its 1998 Stock Option Plan (the  "Plan"),  to
provide the Employee with an  opportunity  to acquire  Common Stock,  $0.001 par
value (hereinafter  referred to as "Common Stock"),  of the Company on favorable
terms and thereby  increase his proprietary  interest in the continued  progress
and success of the business of the Company;

     NOW,  THEREFORE,  in  consideration  of the premises,  the mutual covenants
herein set forth and other good and valuable consideration,  the Company and the
Employee hereby agree as follows:

     1.  Confirmation  of Grant of Option.  Pursuant to a  determination  by the
Board of Directors of the Company, the Company, subject to the terms of the Plan
and this  Agreement,  hereby  grants to the  Employee  as a matter  of  separate
inducement and agreement,  and in addition to and not in lieu of salary or other
compensation for services, the right to purchase (hereinafter referred to as the
"Option") an aggregate of 577,500 shares of Common Stock,  subject to adjustment
as provided in the Plan (such shares, as adjusted, hereinafter being referred to
as the  "Shares").  The Option is not intended to qualify as an incentive  stock
option under  Section 422 of the Internal  Revenue Code of 1986, as amended (the
"Code").

     2. Purchase Price.  The purchase price of shares of Common Stock covered by
the Option will be $0.4375 per share,  subject to  adjustment as provided in the
Plan.

     3. Exercise of Option.  (a) In accordance with the provisions of Section 21
hereof, by his execution and delivery hereof,  the Employee agrees to cancel all
prior options to acquire  shares of Common Stock ("Prior  Options").  The Option
shall be  exercisable  on the terms and  conditions  set forth and in accordance
with the vesting schedule  applicable to the Prior Options, as though the Option
had been granted at the time of the grant of the Prior Options.

     (b) The Option may be exercised  pursuant to the provisions of this Section
3, by notice and payment to the Company as provided in Sections 9 and 14 hereof.

     4. Term of  Option.  The term of the  Option  shall be a period of ten (10)
years

<PAGE>

from the Date of Grant,  subject  to  earlier  termination  or  cancellation  as
provided in this Agreement. This Option, to the extent unexercised, shall expire
on the day  immediately  prior to the tenth  (10th)  anniversary  of the Date of
Grant.  The holder of the Option  shall not have any rights to  dividends or any
other rights of a stockholder with respect to any shares of Common Stock subject
to the Option until such shares  shall have been issued to him (as  evidenced by
the appropriate entry on the books of the Company or a duly authorized  transfer
agent of the Company)  provided  that the date of issuance  shall not be earlier
than the date this Option is exercised and payment of the full purchase price of
the shares of Common Stock (with  respect to which this Option is  exercised) is
made to the Company.

     5.  Non-transferability  of  Option.  The  Option  shall  not be  assigned,
transferred or otherwise disposed of, or pledged or hypothecated in any way, and
shall not be subject to execution, attachment or other process, except as may be
provided in the Plan. Any assignment,  transfer, pledge,  hypothecation or other
disposition of the Option  attempted  contrary to the provisions of the Plan, or
any levy of execution,  attachment or other process  attempted  upon the Option,
will be null  and  void  and  without  effect.  Any  attempt  to make  any  such
assignment,  transfer, pledge,  hypothecation or other disposition of the Option
will cause the Option to terminate  immediately  upon the  happening of any such
event;  provided,  however,  that any such  termination  of the Option under the
foregoing provisions of this Section 5 will not prejudice any rights or remedies
which the Company or any Parent or Subsidiary  may have under this  Agreement or
otherwise.

     6. Exercise Upon Cessation of  Employment.  (a) If the Employee at any time
ceases to be an employee of the Company and of any Parent or  Subsidiary  (i) by
reason of his discharge for Good Cause or (ii) due to his voluntary  termination
of employment without the written consent of the Committee, the Option shall, at
the time of such  termination  of  employment,  terminate and the Employee shall
forfeit all rights  hereunder.  If,  however,  the Employee for any other reason
(other than Disability or death) ceases to be such an Employee,  the Option may,
subject to the  provisions of Section 5 hereof,  be exercised by the Employee to
the same extent the Employee  would have been entitled under Section 3 hereof to
exercise the Option  immediately  prior to such cessation of employment,  at any
time  within 30 days after such  cessation  of  employment,  at the end of which
period the Option,  to the extent not then  exercised,  shall  terminate and the
Employee shall forfeit all rights hereunder,  even if the Employee  subsequently
returns to the employ of the Company or any Parent or  Subsidiary.  In no event,
however,  may the Option be exercised  after the expiration of the term provided
in Section 4 hereof.

     (b) The Option shall not be affected by any change of duties or position of
the Employee as long as he  continues to be a full-time  employee of the Company
or of any Parent or Subsidiary  thereof.  If the Employee is granted a temporary
leave of absence,  such leave of absence shall be deemed a  continuation  of his
employment  by the  Company  or of any  Parent  or  Subsidiary  thereof  for the
purposes of this Agreement, but only if and so long as the employing corporation
consents thereto.

     7. Exercise Upon Death or Disability.  (a) If the Employee dies while he is
employed by the Company or by any Parent or Subsidiary,  the Option may, subject
to the  provisions of Section 5 hereof,  be exercised with respect to all or any
part of the shares of Common  Stock as to which the  deceased  Employee  had not
exercised the Option at the time of his death  (regardless of whether the option
was fully  exercisable  at such time) by the estate of the  Employee  (or by the
person or  persons  who  acquire  the right to  exercise  the  Option by written
designation  of the  Employee) at any time within 90 days after the death of the
Employee,  at the end of  which  period  the  Option,  to the  extent  not  then
exercised,  shall terminate and the estate or other  beneficiaries shall forfeit
all rights hereunder.  In no event,  however,  may the Option be exercised after
the expiration of the term provided in Section 4 hereof.

     8.  Registration.  At the time of  issuance,  the  shares of  Common  Stock
subject hereto and issuable upon the exercise hereof may not be registered under
the  Securities  Act of 1933,  as amended,  and, if required upon the request of
counsel  to the  Company,  the  Employee  will give a  representation  as to his
investment  intent with  respect to such shares  prior to their  issuance as set
forth in Section 8 hereof.  The  Company  may  register  or  qualify  the shares
covered  by the Option  for sale  pursuant  to the  Securities  Act of 1933,  as
amended,  at any time prior to or after the  exercise in whole or in part of the
Option.

     9. Method of Exercise of Option. (a) Subject to the terms and conditions of
this  Agreement,  the Option  shall be  exercisable  by notice in the manner set
forth in  Exhibit A hereto  (the  "Notice")  and  provision  for  payment to the
Company in accordance  with the procedure  prescribed  herein.  Each such Notice
shall:

          (i) state the election to exercise the Option and the number of Shares
     with respect to which it is being exercised;

          (ii) contain a representation  and agreement as to investment  intent,
     if required by counsel to the Company  with  respect to such  Shares,  in a
     form satisfactory to counsel to the Company;

          (iii) be signed by the  Employee or the person or persons  entitled to
     exercise the Option and, if the Option is being  exercised by any person or
     persons other than the Employee,  be accompanied by proof,  satisfactory to
     counsel to the  Company,  of the right of such  other  person or persons to
     exercise the Option;

          (iv)  include  payment  of the full  purchase  price for the shares of
     Common Stock to be purchased pursuant to such exercise of the Option; and

          (v) be received by the Company on or before the date of the expiration
     of this Option. In the event the date of expiration of this Option falls on
     a day which is not a regular business day at the Company's executive office
     in New York,  New York then

<PAGE>

     such  written  Notice must be received at such office on or before the last
     regular business day prior to such date of expiration.

     (b) Payment of the purchase price of any shares of Common Stock, in respect
of which the Option  shall be  exercised,  shall be made by the Employee or such
person or persons at the place  specified  by the Company on the date the Notice
is received by the Company (i) by  delivering to the Company a certified or bank
cashier's check payable to the order of the Company, (ii) if consented to by the
Company in writing, by delivering to the Company properly endorsed  certificates
of shares of Common Stock (or certificates  accompanied by an appropriate  stock
power) with  signature  guaranties by a bank or trust  company,  (iii) by having
withheld from the total number of shares of Common Stock to be acquired upon the
exercise of this Option a specified number of such shares of Common Stock,  (iv)
by any form of "cashless"  exercise or (v) by any  combination of the foregoing.
For purposes of the immediately  preceding sentence, an exercise effected by the
tender of the  Common  Stock (or deemed to be  effected  by the tender of Common
Stock) may be  consummated  only with Common  Stock (i) held by the Employee for
six (6) months or (ii) acquired by the Employee  other than under the Plan (or a
similar plan maintained by the Company).

     (c) The Option shall be deemed to have been  exercised  with respect to any
particular  shares of Common Stock if, and only if, the preceding  provisions of
this Section 9 and the  provisions of Section 10 hereof shall have been complied
with,  in which event the Option  shall be deemed to have been  exercised on the
date the Notice and related  payment were  received by the Company.  Anything in
this Agreement to the contrary notwithstanding, any Notice given pursuant to the
provisions  of this  Section  9 shall  be void  and of no  effect  if all of the
preceding  provisions  of this Section 9 and the  provisions of Section 10 shall
not have been complied with.

     (d) The certificate or certificates  for shares of Common Stock as to which
the Option shall be exercised will be registered in the name of the Employee (or
in the name of the  Employee's  estate  or other  beneficiary  if the  Option is
exercised  after the  Employee's  death),  or if the Option is  exercised by the
Employee  and if the Employee so requests in the notice  exercising  the Option,
will be registered in the name of the Employee and another person jointly,  with
right of survivorship  and will be delivered as soon as practical after the date
the  Notice is  received  by the  Company  (accompanied  by full  payment of the
exercise  price),  but only upon  compliance  with all of the provisions of this
Agreement.

     (e) If the Employee fails to accept delivery of and pay for all or any part
of the number of Shares  specified  in such  Notice,  his right to exercise  the
Option with respect to such  undelivered  Shares may be  terminated  in the sole
discretion of the  Committee.  The Option may be exercised  only with respect to
full Shares.

     (f) The Company  shall not be required to issue or deliver any  certificate
or  certificates  for shares of its Common Stock  purchased upon the exercise of
any part of the Option prior to the payment to the Company,  upon its demand, of
any amount requested by the

<PAGE>

Company  for the  purpose of  satisfying  its  liability,  if any,  to  withhold
federal,  state or local income or earnings tax or any other  applicable  tax or
assessment  (plus interest or penalties  thereon,  if any,  caused by a delay in
making such  payment)  incurred by reason of the  exercise of this Option or the
transfer of shares thereupon. Such payment shall be made by the Employee in cash
or, with the written consent of the Company,  by tendering to the Company shares
of Common Stock equal in value to the amount of the required withholding. In the
alternative,   the  Company  may,  at  its  option,   satisfy  such  withholding
requirements  by withholding  from the shares of Common Stock to be delivered to
the Employee  pursuant to an exercise of the Option a number of shares of Common
Stock equal in value to the amount of the required withholding.

     10.  Approval of Counsel.  The  exercise of the Option and the issuance and
delivery of shares of Common Stock pursuant thereto shall be subject to approval
by  the  Company's  counsel  of  all  legal  matters  in  connection  therewith,
including,  but  not  limited  to,  compliance  with  the  requirements  of  the
Securities Act of 1933, as amended,  and the Securities Exchange Act of 1934, as
amended, and the rules and regulations  thereunder,  and the requirements of any
stock exchange or automated  trading medium upon which the Common Stock may then
be listed or traded.

     11.  Resale of Common Stock.  (a) If so requested by the Company,  upon any
sale or transfer of the Common Stock  purchased  upon exercise of the Option the
Employee shall deliver to the Company an opinion of counsel  satisfactory to the
Company to the effect that either (i) the Common Stock to be sold or transferred
has been registered under the Securities Act of 1933, as amended, and that there
is in effect a current  prospectus  meeting the requirements of Section 10(a) of
said Act which is being or will be delivered to the  purchaser or  transferee at
or prior to the time of delivery of the certificates evidencing the Common Stock
to be sold or  transferred,  or (ii) such Common  Stock may then be sold without
violating Section 5 of said Act.

     (b) The Common  Stock  issued upon  exercise  of the Option  shall bear the
following (or similar) legend if required by counsel for the Company:

                  THE  SHARES  EVIDENCED  BY THIS  CERTIFICATE  MAY NOT BE SOLD,
                  TRANSFERRED,  PLEDGED,  HYPOTHECATED OR OTHERWISE  DISPOSED OF
                  UNLESS THEY HAVE FIRST BEEN  REGISTERED  UNDER THE  SECURITIES
                  ACT OF 1933, AS AMENDED,  OR UNLESS, IN THE OPINION OF COUNSEL
                  FOR THE COMPANY, SUCH REGISTRATION IS NOT REQUIRED.

     12.  Reservation of Shares.  The Company shall at all times during the term
of the Option  reserve  and keep  available  such number of shares of the Common
Stock as will be sufficient to satisfy the requirements of this Agreement.

     13.  Limitation of Action.  The Employee and the Company each  acknowledges
<PAGE>

that  every  right of  action  accruing  to him or it,  as the case may be,  and
arising out of or in  connection  with this  Agreement  against the Company or a
Parent or  Subsidiary,  on the one hand, or against the  Employee,  on the other
hand, shall, irrespective of the place where an action may be brought, cease and
be barred by the  expiration of three years from the date of the act or omission
in respect of which such right of action arises.

     14. Notices. Each notice relating to this Agreement shall be in writing and
delivered in person, by recognized overnight carrier or by certified mail to the
proper  address.  All notices to the Company or the Committee shall be addressed
to them at 150 E. 58th Street,  New York, NY 10155-1596,  Attn:  President.  All
notices to the Employee  shall be addressed to the Employee or such other person
or persons at the Employee's  address above  specified.  Anyone to whom a notice
may be given under this  Agreement may designate a new address by notice to that
effect.

     15. Benefits of Agreement. This Agreement shall inure to the benefit of the
Company,  the Employee and their respective  heirs,  executors,  administrators,
personal representatives, successors and assigns.

     16.  Severability.  In the event  that any one or more  provisions  of this
Agreement  shall be deemed to be illegal or  unenforceable,  such  illegality or
unenforceability  shall  not  affect  the  validity  and  enforceability  of the
remaining legal and enforceable  provisions hereof,  which shall be construed as
if such illegal or unenforceable provision or provisions had not been inserted.

     17.  Governing  Law.  This  Agreement  will be  construed  and  governed in
accordance with the laws of the State of Delaware.

     18.  Employment.  Nothing contained in this Agreement shall be construed as
(a) a contract of employment  between the Employee and the Company or any Parent
or  Subsidiary,  (b) as a right of the Employee to be continued in the employ of
the Company or of any Parent or Subsidiary,  or (c) as a limitation of the right
of the Company or of any Parent or  Subsidiary  to discharge the Employee at any
time, with or without cause (subject to any applicable employment agreement).

     19.  Definitions.  Unless otherwise  defined herein,  all capitalized terms
used in this Agreement shall have the same definitions as set forth in the Plan.

     20.  Incorporation  of Terms of Plan.  This Agreement  shall be interpreted
under,  and subject to, all of the terms and  provisions of the Plan,  which are
incorporated herein by reference.

     21.  Cancellation of Prior Option. By executing this Agreement the Employee
hereby agrees that effective as of December 15, 1998, of all of his rights under
