     certificate for the number of Warrant Shares equal to the quotient obtained
     by dividing [(A-B) (X)] by (A), where:

                                       2

               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.

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

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

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

require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

     purpose,  upon  surrender  of this Warrant at the  principal  office of the
     Company,  together with a written assignment of this Warrant  substantially

     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

     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)  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

                                       4

(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  evidences  of  indebtedness,
shares of stock or other  securities  which are convertible into or

                                       5

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 which the  holders of Common  Stock shall be entitled to any
such dividend, distribution or right,

                                       6

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.

                                       7

               (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.

                                       8

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.
