                                       1


          1. Title to  Warrant.  Prior to the  Termination  Date and  subject to
compliance  with  applicable  laws,  this Warrant and all rights  hereunder  are
transferable, in whole or in part, at the office or agency of the Company by the
Holder in person or by duly authorized attorney,  upon surrender of this Warrant
together with the Assignment Form annexed hereto properly endorsed.

          2.  Authorization  of Shares.  The Company  covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights  represented
by this Warrant will, upon exercise of the purchase  rights  represented by this
Warrant,  be duly authorized,  validly issued,  fully paid and nonassessable and
free from all taxes,  liens and charges in respect of the issue  thereof  (other
than (x) taxes in respect of any transfer occurring  contemporaneously with such
issue) and (y) liens and  charges  created by the  then-current  Holder,  or any
former Holder of this Warrant).

          3. Exercise of Warrant.

          (a) Except as provided in Section 4 herein,  exercise of the  purchase
     rights  represented  by this Warrant may be made at any time or times on or
     after the Initial  Exercise  Date and on or before the close of business on
     the  Termination  Date by the  surrender  of this Warrant and the Notice of
     Exercise Form annexed  hereto duly  executed,  at the office of the Company
     (or such  other  office or agency of the  Company  as it may  designate  by
     notice in writing to the  registered  Holder at the  address of such Holder
     appearing  on the books of the  Company)  and upon payment on or before the
     Termination  Date of the Exercise Price of the shares thereby  purchased by
     wire transfer or cashier's check drawn on a United States bank, or by means
     of a  cashless  exercise,  the  Holder  shall  be  entitled  to  receive  a
     certificate for the number of Warrant Shares so purchased. Certificates for
     shares  purchased  hereunder  shall be delivered to the Holder within three
     (3)  Trading  Days  after the date on which  this  Warrant  shall have been
     exercised as aforesaid. This Warrant shall be deemed to have been exercised
     and such  certificate or certificates  shall be deemed to have been issued,
     and Holder or any other person so  designated  to be named therein shall be
     deemed to have become a holder of record of such  shares for all  purposes,
     as of the date the Warrant has been  exercised by payment to the Company of
     the Exercise Price and all taxes required to be paid by the Holder, if any,
     pursuant to Section 5 prior to the issuance of such shares, have been paid.
     If the Company fails to deliver to the Holder a certificate or certificates
     representing  the Warrant Shares pursuant to this Section 3(a) by the fifth
     Trading Day after the date of exercise, then the Holder will have the right
     to rescind such exercise.  In addition to any other rights available to the
     Holder,  if the  Company  fails to deliver to the Holder a  certificate  or
     certificates representing the Warrant Shares pursuant to an exercise by the
     eighth  Trading  Day after the date of  exercise,  and if after such eighth
     Trading  Day  the  Holder  purchases  (in an  open  market  transaction  or
     otherwise)  shares of Common Stock to deliver in  satisfaction of a sale by
     the Holder of the Warrant  Shares  which the Holder  anticipated  receiving
     upon such exercise (a "Buy-In"),  then the Company shall (1) pay in cash to
     the  Holder  the  amount by which (x) the  Holder's  total  purchase  price
     (including brokerage commissions, if any) for the shares of Common Stock so
     purchased exceeds

                                       2


          (y) the  amount  obtained  by  multiplying  (A) the  number of Warrant
     Shares that the Company was required to deliver to the Holder in connection
     with the  exercise  at issue  times (B) the closing bid price of the Common
     Stock  at  the  time  of  the  obligation  giving  rise  to  such  purchase
     obligation,  and (2) at the  option of the  Holder,  either  reinstate  the
     portion of the Warrant and  equivalent  number of Warrant  Shares for which
     such exercise was not honored or deliver to the Holder the number of shares
     of Common Stock that would have been issued had the Company timely complied
     with its exercise and delivery obligations  hereunder.  For example, if the
     Holder  purchases  Common Stock having a total purchase price of $11,000 to
     cover a Buy-In with  respect to an  attempted  exercise of shares of Common
     Stock with a market price on the date of exercise  totaled  $10,000,  under
     clause (1) of the  immediately  preceding  sentence  the  Company  shall be
     required to pay the Holder  $1,000.  The Holder  shall  provide the Company
     written notice  indicating the amounts  payable to the Holder in respect of
     the Buy-In. Nothing herein shall limit a Holder's right to pursue any other
     remedies available to it hereunder, at law or in equity including,  without
     limitation,  a decree of specific performance and/or injunctive relief with
     respect  to  the   Company's   failure  to  timely   deliver   certificates
     representing  shares  of Common  Stock  upon  exercise  of the  Warrant  as
     required pursuant to the terms hereof.

          (b) If this Warrant  shall have been  exercised  in part,  the Company
     shall,  at  the  time  of  delivery  of  the  certificate  or  certificates
     representing Warrant Shares, deliver to Holder a new Warrant evidencing the
     rights of Holder to purchase the  unpurchased  Warrant Shares called for by
     this Warrant,  which new Warrant  shall in all other  respects be identical
     with this Warrant.

          (c) This  Warrant  shall also be  exercisable  by means of a "cashless
     exercise"  in which the Holder  shall be entitled to receive a  certificate
     for the number of Warrant Shares equal to the quotient obtained by dividing
     [(A-B) (X)] by (A), where:

               (A) = the closing price per share of Common Stock (as reported by
               the American Stock Exchange (or principal market)) on the Trading
               Day  preceding  the date of such  election on the American  Stock
               Exchange,  or if the Common  Stock is not traded on the  American
               Stock Exchange, then the Principal Market in terms of volume;

               (B) = the Exercise Price of this Warrant; and

               (X) = the number of Warrant Shares issuable upon exercise of
               this Warrant in accordance with the terms of this Warrant and the
               Notice of Exercise.

          (d) Notwithstanding anything herein to the contrary, in no event shall
     the Holder be permitted to exercise this Warrant for Warrant  Shares to the
     extent  that (i) the number of shares of Common  Stock owned by such Holder
     (other than Warrant  Shares  issuable  upon  exercise of this Warrant) plus
     (ii) the number of Warrant  Shares  issuable upon exercise of this Warrant,
     would be equal to or exceed  9.9% of the  number of shares of Common  Stock
     then issued and  outstanding,  including  shares  issuable upon exercise of
     this Warrant held by such Holder after application of this Section 3(d). As
     used

                                       3


     herein, beneficial ownership shall be determined in accordance with Section
     13(d) of the Exchange Act. To the extent that the  limitation  contained in
     this Section 3(d)  applies,  the  determination  of whether this Warrant is
     exercisable  (in relation to other  securities  owned by the Holder) and of
     which a  portion  of this  Warrant  is  exercisable  shall  be in the  sole
     discretion of such Holder, and the submission of a Notice of Exercise shall
     be  deemed  to  be  such  Holder's  determination  of  whether,  and  shall
     constitute a representation  and warranty by the Holder to the effect that,
     this Warrant is exercisable (in relation to other  securities owned by such
     Holder) and of which portion of this Warrant is  exercisable,  in each case
     subject to such aggregate percentage limitation, and the Company shall have
     no obligation to verify or confirm the accuracy of such  determination (but
     shall be  entitled  to do so, in its sole  discretion).  Nothing  contained
     herein shall be deemed to restrict  the right of a Holder to exercise  this
     Warrant into Warrant  Shares at such time as such exercise will not violate
     the provisions of this Section 3(d).


          4. No  Fractional  Shares  or  Scrip.  No  fractional  shares or scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant.  As to any fraction of a share which Holder would otherwise be entitled
to purchase  upon such  exercise,  the Company  shall pay a cash  adjustment  in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

          5. Charges,  Taxes and Expenses.  Issuance of certificates for Warrant
Shares shall be made without  charge to the Holder for any issue or transfer tax
or other incidental expense in respect of the issuance of such certificate,  all
of which taxes and expenses shall be paid by the Company,  and such certificates
shall be  issued  in the name of the  Holder  or in such name or names as may be
directed by the Holder;  provided,  however,  that in the event certificates for
Warrant  Shares are to be issued in a name  other  than the name of the  Holder,
this  Warrant  when  surrendered  for  exercise  shall  be  accompanied  by  the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

          6. [Reserved].

          7. Transfer, Division and Combination.

          (a)  Subject  to  compliance  with  any  applicable  securities  laws,
     transfer  of this  Warrant and all rights  hereunder,  in whole or in part,
     shall be registered  on the books of the Company to be maintained  for such
     purpose,  upon  surrender  of this Warrant at the  principal  office of the
     Company,  together with a written assignment of this Warrant  substantially
     in the form  attached  hereto  duly  executed by the Holder or its agent or
     attorney and funds  sufficient  to pay any transfer  taxes payable upon the
     making of such transfer.  In the event that the Holder wishes to transfer a
     portion of this Warrant,  the Holder shall  transfer at least 25,000 shares
     underlying this Warrant to any such transferee. Upon such surrender and, if
     required, such payment, the Company shall execute and deliver a new Warrant
     or  Warrants  in  the  name  of  the  assignee  or  assignees  and  in  the
     denomination or  denominations  specified in such instrument of assignment,
     and shall  issue to the  assignor a new Warrant  evidencing  the portion of
     this Warrant not

                                       4


     so assigned,  and this Warrant shall promptly be cancelled.  A Warrant,  if
     properly  assigned,  may be  exercised  by a new holder for the purchase of
     Warrant  Shares without having a new Warrant  issued.  Notwithstanding  the
     above,  the Holder shall not transfer this warrant or any rights  hereunder
     to any  person or entity  which is  engaged  in a  business  that is in the
     reasonable judgment of the Company is in competition with the Company.

          (b) This Warrant may be divided or combined  with other  Warrants upon
     presentation hereof at the aforesaid office of the Company, together with a
     written notice specifying the names and denominations in which new Warrants
     are to be issued, signed by the Holder or its agent or attorney. Subject to
     compliance  with Section 7(a), as to any transfer  which may be involved in
     such division or  combination,  the Company shall execute and deliver a new
     Warrant or Warrants  in exchange  for the Warrant or Warrants to be divided
     or combined in accordance with such notice.

          (c) The Company  shall  prepare,  issue and deliver at its own expense
     (other than transfer  taxes) the new Warrant or Warrants under this Section
     7.

          (d) The Company agrees to maintain, at its aforesaid office, books for
     the registration and the registration of transfer of the Warrants.

          8. No Rights as  Shareholder  until  Exercise.  This  Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder  of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price or by means of a cashless exercise,  the
Warrant  Shares so purchased  shall be and be deemed to be issued to such Holder
as the record  owner of such  shares as of the close of business on the later of
the date of such surrender or payment.

          9. Loss,  Theft,  Destruction  or Mutilation  of Warrant.  The Company
covenants that upon receipt by the Company of evidence  reasonably  satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate  relating  to the  Warrant  Shares,  and in case of  loss,  theft or
destruction, of indemnity or security reasonably satisfactory to it (which shall
not include the posting of any bond),  and upon  surrender and  cancellation  of
such  Warrant or stock  certificate,  if  mutilated,  the Company  will make and
deliver a new  Warrant or stock  certificate  of like tenor and dated as of such
cancellation, in lieu of such Warrant or stock certificate.

          10. Saturdays,  Sundays,  Holidays,  etc. If the last or appointed day
for the taking of any action or the  expiration of any right required or granted
herein shall be a Saturday,  Sunday or a legal holiday,  then such action may be
taken or such right may be exercised on the next  succeeding day not a Saturday,
Sunday or legal holiday.

          11.  Adjustments  of Exercise  Price and Number of Warrant  Shares for
Stock  Splits,  etc.  The number  and kind of  securities  purchasable  upon the
exercise of this Warrant and the Exercise  Price shall be subject to  adjustment
from  time to time  upon  the  happening  of any of the  following.  In case the
Company  shall  (i)  pay a  dividend  in  shares  of  Common  Stock  or  make  a
distribution  in shares of Common  Stock to  holders of its  outstanding  Common
Stock,  (ii)

                                       5


subdivide  its  outstanding  shares of  Common  Stock  into a greater  number of
shares,  (iii)  combine its  outstanding  shares of Common  Stock into a smaller
number of shares of Common Stock,  or (iv) issue any shares of its capital stock
in a  reclassification  of the Common Stock,  then the number of Warrant  Shares
purchasable  upon  exercise of this Warrant  immediately  prior thereto shall be
adjusted so that the Holder  shall be entitled to receive the kind and number of
Warrant  Shares or other  securities of the Company which it would have owned or
have been  entitled  to  receive  had such  Warrant  been  exercised  in advance
thereof.  Upon each such  adjustment of the kind and number of Warrant Shares or
other  securities of the Company  which are  purchasable  hereunder,  the Holder
shall  thereafter be entitled to purchase the number of Warrant  Shares or other
securities resulting from such adjustment at an Exercise Price per Warrant Share
or  other  security  obtained  by  multiplying  the  Exercise  Price  in  effect
immediately prior to such adjustment by the number of Warrant Shares purchasable
pursuant hereto  immediately prior to such adjustment and dividing by the number
of  Warrant  Shares  or other  securities  of the  Company  resulting  from such
adjustment. An adjustment made pursuant to this paragraph shall become effective
immediately  after the effective  date of such event  retroactive  to the record
date, if any, for such event.


          12.  Reorganization,   Reclassification,   Merger,   Consolidation  or
Disposition  of  Assets.  In case the  Company  shall  reorganize  its  capital,
reclassify  its  capital  stock,  consolidate  or  merge  with or  into  another
corporation  (where the Company is not the surviving  corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business  to another  corporation  and,  pursuant to the terms of such
reorganization,   reclassification,  merger,  consolidation  or  disposition  of
assets, shares of common stock of the successor or acquiring corporation, or any
cash,  shares of stock or other securities or property of any nature  whatsoever
(including  warrants or other subscription or purchase rights) in addition to or
in lieu of  common  stock of the  successor  or  acquiring  corporation  ("Other
Property"),  are to be received by or distributed to the holders of Common Stock
of the  Company,  then the Holder  shall have the right  thereafter  to elect to
receive,  (i) upon exercise of this Warrant at the Exercise Price written herein
and  consummation of the applicable  event, the number of shares of Common Stock
of the  successor  or  acquiring  corporation  or of the  Company,  if it is the
surviving corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common  Stock for which  this  Warrant is
exercisable  immediately prior to such event, or (ii) cash equal to the value of
this Warrant as determined in accordance with the  Black-Scholes  option pricing
formula.  In  case  of  any  such  reorganization,   reclassification,   merger,
consolidation or disposition of assets,  the successor or acquiring  corporation
(if  other  than  the  Company)  shall  expressly  assume  the due and  punctual
observance  and  performance  of each and every  covenant and  condition of this
Warrant to be performed and observed by the Company and all the  obligations and
liabilities   hereunder,   subject  to  such  modifications  as  may  be  deemed
appropriate (as determined in good faith by resolution of the Board of Directors
of the Company) in order to provide for  adjustments of Warrant Shares for which
this Warrant is exercisable  which shall be as nearly  equivalent as practicable
to the adjustments provided for in this Section 12. For purposes of this Section
12, "common stock of the successor or acquiring corporation" shall include stock
of such  corporation  of any class which is not  preferred  as to  dividends  or
assets  over any  other  class of stock  of such  corporation  and  which is not
subject to  redemption  and shall also include any

                                       6


evidences  of  indebtedness,  shares  of  stock or other  securities  which  are
convertible into or exchangeable for any such stock,  either immediately or upon
the arrival of a specified  date or the  happening of a specified  event and any
warrants  or other  rights to  subscribe  for or purchase  any such  stock.  The
foregoing  provisions  of this Section 12 shall  similarly  apply to  successive
reorganizations,  reclassifications,  mergers,  consolidations or disposition of
assets.

          13. Voluntary  Adjustment by the Company.  The Company may at any time
during the term of this Warrant  reduce the then current  Exercise  Price to any
amount and for any period of time deemed  appropriate  by the Board of Directors
of the Company.

          14.  Notice of  Adjustment.  Whenever the number of Warrant  Shares or
number or kind of securities or other property  purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided,  the Company
shall promptly mail by registered or certified mail,  return receipt  requested,
to the Holder notice of such adjustment or adjustments  setting forth the number
of Warrant  Shares  (and other  securities  or  property)  purchasable  upon the
exercise of this  Warrant and the  Exercise  Price of such  Warrant  Shares (and
other  securities  or property)  after such  adjustment,  setting  forth a brief
statement  of  the  facts  requiring  such  adjustment  and  setting  forth  the
computation by which such  adjustment was made.  Such notice,  in the absence of
manifest  error,  shall  be  conclusive  evidence  of the  correctness  of  such
adjustment.

          15. Notice of Corporate Action. If at any time:

          (a) the Company shall take a record of the holders of its Common Stock
     for  the  purpose  of  entitling  them  to  receive  a  dividend  or  other
     distribution,  or any right to subscribe  for or purchase any  evidences of
     its indebtedness,  any shares of stock of any class or any other securities
     or property, or to receive any other right, or

          (b) there  shall be any capital  reorganization  of the  Company,  any
     reclassification or recapitalization of the capital stock of the Company or
     any  consolidation or merger of the Company with, or any sale,  transfer or
     other  disposition  of all or  substantially  all the  property,  assets or
     business of the Company to, another corporation or,

          (c) there shall be a voluntary or involuntary dissolution, liquidation
     or winding up of the Company;

then,  in any one or more of such cases,  the Company  shall give to Holder,  if
lawful and  practicable  to do so, (i) at least 10 days' prior written notice of
the  date  on  which  a  record  date  shall  be  selected  for  such  dividend,
distribution or right or for  determining  rights to vote in respect of any such
reorganization,   reclassification,   merger,  consolidation,   sale,  transfer,
disposition,  liquidation  or  winding  up,  and  (ii) in the  case of any  such
reorganization,   reclassification,   merger,  consolidation,   sale,  transfer,
disposition,  dissolution,  liquidation  or winding  up, at least 10 days' prior
written  notice of the date  when the same  shall  take  place.  Such  notice in
accordance  with the  foregoing  clause also shall specify (i) the date on which
any such record is to be taken for the purpose of such dividend, distribution or
right,  the date on

                                       7


which the  holders  of Common  Stock  shall be  entitled  to any such  dividend,
distribution or right, and the amount and character  thereof,  and (ii) the date
on which any such reorganization, reclassification, merger, consolidation, sale,
transfer, disposition,  dissolution,  liquidation or winding up is to take place
and the time, if any such time is to be fixed, as of which the holders of Common
Stock shall be entitled to exchange their Warrant Shares for securities or other
property deliverable upon such disposition,  dissolution, liquidation or winding
up. Each such written notice shall be sufficiently  given if addressed to Holder
at the  last  address  of  Holder  appearing  on the  books of the  Company  and
delivered in accordance with Section 17(d).

          16.  Authorized  Shares.  The Company covenants that during the period
the Warrant is  outstanding,  it will reserve from its  authorized  and unissued
Common  Stock a  sufficient  number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant.  The
Company  represents  that its issuance of this  Warrant  shall  constitute  full
authority  to its  officers  who are charged  with the duty of  executing  stock
certificates  to execute and issue the  necessary  certificates  for the Warrant
Shares upon the exercise of the purchase rights under this Warrant.  The Company
will take all such  reasonable  action as may be  necessary  to assure that such
Warrant  Shares  may be issued  as  provided  herein  without  violation  of any
applicable law or regulation,  or of any  requirements  of the Principal  Market
upon which the Common Stock may be listed.

               The  Company  shall  not  by  any  action,   including,   without
limitation,   amending  its   certificate  of   incorporation   or  through  any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities  or any other  voluntary  action,  avoid or seek to avoid the
observance or performance  of any of the terms of this Warrant,  but will at all
times in good  faith  assist in the  carrying  out of all such  terms and in the
taking of all such  actions as may be necessary  or  appropriate  to protect the
rights of Holder  against  impairment.  Without  limiting the  generality of the
foregoing, the Company will (a) not increase the par value of any Warrant Shares
above the amount payable therefor upon such exercise  immediately  prior to such
increase in par value, (b) use commercially  reasonable efforts to take all such
action as may be necessary or  appropriate in order that the Company may validly
and legally issue fully paid and nonassessable  Warrant Shares upon the exercise
of this Warrant, and (c) use commercially  reasonable efforts to obtain all such
authorizations,  exemptions or consents from any public  regulatory  body having
jurisdiction  thereof as may be  necessary  to enable the Company to perform its
obligations under this Warrant.

               Before  taking any action which would result in an  adjustment in
the number of Warrant  Shares for which this  Warrant is  exercisable  or in the
Exercise Price, the Company shall obtain all such  authorizations  or exemptions
thereof,  or consents  thereto,  as may be necessary from any public  regulatory
body or bodies having jurisdiction thereof.

          17. Miscellaneous.

          (a)  Jurisdiction.  This Warrant shall constitute a contract under the
     laws of New York,  without  regard to its  conflict of law,  principles  or
     rules, and be subject to arbitration pursuant to the terms set forth in the
     Purchase Agreement.

                                       8


          (b)  Restrictions.  The Holder  acknowledges  that the Warrant  Shares
     acquired upon the exercise of this Warrant,  if not  registered,  will have
     restrictions upon resale imposed by state and federal securities laws.

          (c)  Nonwaiver  and  Expenses.  No course of  dealing  or any delay or
     failure to exercise any right hereunder on the part of Holder shall operate
     as a waiver of such right or otherwise prejudice Holder's rights, powers or
     remedies, notwithstanding all rights hereunder terminate on the Termination
     Date.  If the  Company  willfully  and  knowingly  fails to comply with any
     provision of this  Warrant,  which  results in any material  damages to the
     Holder, the Company shall pay to Holder such amounts as shall be sufficient
     to cover any costs and expenses  including,  but not limited to, reasonable
     attorneys'  fees,  including  those of appellate  proceedings,  incurred by
     Holder in  collecting  any  amounts  due  pursuant  hereto or in  otherwise
     enforcing any of its rights, powers or remedies hereunder.

          (d)  Notices.  Any  notice,  request  or other  document  required  or
     permitted to be given or  delivered  to the Holder by the Company  shall be
     delivered  in  accordance  with  the  notice  provisions  of  the  Purchase
     Agreement.

          (e) Limitation of Liability.  No provision  hereof,  in the absence of
     affirmative action by Holder to purchase Warrant Shares, and no enumeration
     herein of the  rights  or  privileges  of  Holder,  shall  give rise to any
     liability  of Holder for the  purchase  price of any  Common  Stock or as a
     stockholder  of the  Company,  whether  such  liability  is asserted by the
     Company or by creditors of the Company.

          (f) Remedies.  Holder,  in addition to being  entitled to exercise all
     rights granted by law, including  recovery of damages,  will be entitled to
     specific  performance of its rights under this Warrant.  The Company agrees
     that  monetary  damages  would not be  adequate  compensation  for any loss
     incurred by reason of a breach by it of the  provisions of this Warrant and
     hereby  agrees to waive the defense in any action for specific  performance
     that a remedy at law would be adequate.

          (g) Successors and Assigns.  Subject to applicable securities laws and
     the provisions of this Warrant, this Warrant and the rights and obligations
     evidenced  hereby  shall  inure to the  benefit of and be binding  upon the
     successors  of the  Company and the  successors  and  permitted  assigns of
     Holder.  The  provisions of this Warrant are intended to be for the benefit
     of all Holders from time to time of this  Warrant and shall be  enforceable
     by any such Holder or holder of Warrant Shares.

          (h)  Amendment.  This  Warrant  may  be  modified  or  amended  or the
     provisions  hereof  waived with the written  consent of the Company and the
     Holder.

          (i) Severability.  Wherever  possible,  each provision of this Warrant
     shall be  interpreted  in such  manner as to be  effective  and valid under
     applicable law, but if any provision of this Warrant shall be prohibited by
     or invalid under applicable law, such provision shall be ineffective to the
     extent  of  such  prohibition  or  invalidity,   without  invalidating  the
     remainder of such provisions or the remaining provisions of this Warrant.

                                       9


          (j)  Headings.   The  headings  used  in  this  Warrant  are  for  the
     convenience of reference  only and shall not, for any purpose,  be deemed a
     part of this Warrant.

                                       10



          IN WITNESS WHEREOF, the Company has caused this Warrant to be executed
by its officer thereunto duly authorized.

Gentlemen:
The undersigned,  registered  Holder of the Warrant delivered  herewith,  hereby
irrevocably exercises such Warrant for, and purchases thereunder,  shares of the
Common Stock of eMagin Corporation,  a Delaware corporation,  as provided below.
Capitalized terms used herein,  unless otherwise defined herein,  shall have the
meanings  given in the  Warrant.  Holder  hereby  exercises  this Warrant for an
aggregate  of  __________  shares,  leaving  __________  shares  remaining to be
exercised.  Such exercise shall be pursuant to the cashless exercise  provisions
of Section 3 of the Warrant; therefore, Holder makes no payment with this Notice
of Exercise and  authorizes the Company to reduce the number of shares of Common
Stock  to be  delivered  pursuant  to  the  immediately  preceding  sentence  in
accordance  with  Section  3.  Holder  requests  that the  certificates  for the
purchased    shares   of    Common    Stock   be   issued   in   the   name   of
_________________________ and delivered to ____________________________________.
To the extent the foregoing  exercise is for less than the full Aggregate  Price
of  the  Warrant,  a  replacement  Warrant  representing  the  remainder  of the
Aggregate  Price  (and  otherwise  of like  form,  tenor  and  effect)  shall be
delivered to Holder along with the share certificate evidencing the Common Stock
issued in response to this Notice of Exercise.
