                     REDUCTION OF EXERCISE PRICE OF WARRANTS

          On  January  9,  2004,  eMagin   Corporation  and  several  accredited
institutional and private investors entered into a Securities Purchase Agreement
whereby such  investors  purchased  an  aggregate of 3,333,364  shares of common
stock for an aggregate purchase price of $4,200,039.

          The  shares of common  stock  were  priced  at a 20%  discount  to the
average  closing  price of the stock from  December 30, 2003 to January 6, 2004,
which  ranged  from  $1.38 to $1.94 per share  during  the period for an average
closing price of $1.26 per share.

          In addition,  the investors received warrants to purchase an aggregate
of  2,000,019  shares of common  stock  (subject to  anti-dilution  adjustments)
exercisable  at a price of $1.74 per share for a period of five (5)  years.  The
warrants were priced at a 10% premium to the average  closing price of the stock
for the pricing period.  eMagin also issued additional warrants to the investors
to acquire an aggregate of 2,312,193  shares of common stock.  1,206,914 of such
warrants  are  exercisable,  within 6  months  from  the  effective  date of the
registration statement covering these securities,  at a price of $1.74 per share
(a 10%  premium  to the  average  closing  price of the  stock  for the  pricing
period),  and 1,105,279 of such warrants are  exercisable  within 12 months from
the effective date of the registration statement covering these securities, at a
price of $1.90 per share (a 20%  premium  to the  average  closing  price of the
stock for the pricing period).

          On  August 3,  2004,  in  consideration  of (i) the  warrant  holders'
agreement to immediately  exercise  their  respective  warrants;  and (ii) limit
certain  rights of  participation  of such warrant  holders,  eMagin  offered to
reduce the exercise price of the Class A, B and C warrants from $1.74, $1.74 and
$1.90  per  share,  respectively  to $0.90  per  share.  The  offer was open for
acceptance by the warrant  holders until August 5, 2004.  All other terms of the
warrants, including their expiry date, were to remain the same.


                                      -2-


          As a result of the  transaction,  the holders  have agreed to re-price
and  exercise,  for an aggregate of  approximately  $1,889,900,  an aggregate of
2,099,894 Class A, B and/or C common stock purchase warrants.

          The  Class B common  stock  purchase  warrants  were due to  expire on
August 12, 2004,  while the Class A and C common stock purchase  warrants remain
exercisable until January 9, 2009 and February 12, 2005, respectively. Following
the completion of the transaction,  the Company continues to have outstanding an
aggregate of 1,213,352 and 184,212 Class A and C common stock purchase warrants,
respectively.  The remaining outstanding  unexercised Class A and C common stock
