To the Purchasers of the  securities  under the  Securities  Purchase  Agreement
Dated  January  9,  2004  set  forth  on the  attached  Distribution  List  (the
"Investors")

Gentlemen:

     As you know,  we have made an offer to you  regarding  the  re-pricing  and
exercise of the  currently  outstanding  Class A, B and C common stock  purchase
warrants of the eMagin  Corporation  that you possess in  consideration  of your
agreeing to limit the right of  participation  that you were granted pursuant to
Section 4.11 of the Securities Purchase  Agreement,  dated January 9, 2004, that
was executed in connection with your investment in common stock and common stock
purchase warrants of eMagin.

     Accordingly,  by way of this  letter,  we are  hereby  requesting  that you
execute  and  return  this  letter  in  order  to  formally   confirm   that  in
consideration of our agreeing to re-price your choice of any of your outstanding
Class A, B and C common stock  purchase  warrants  from $1.74,  $1.74 and $1.90,
respectively,  to $.90  per  share,  you  agree  to:  (i)  limit  your  right of
participation  with respect any proposed  financing  transaction  to the maximum
number  of shares  that  AMEX  will  allow  the  Investors  to  purchase  in any
subsequent  financing  without the Company  being  required to seek  shareholder
approval  (provided,  however,  that in no event will the  participation  of all
investors of the January 2004 financing in any such subsequent  financing exceed
35% of such financing);  and (ii) immediately  exercise the re-priced Class A, B
and C common stock purchase warrants as per the attached signature page.

     In  consultation  with our legal  counsel,  we have  determined  that it is
appropriate for us to file prospectus  supplements disclosing the adjustments to
the exercise price of your warrants.  As a selling stockholder under the related
Registration Statements, you are subject to the prospectus delivery requirements
under  section 5(b) of the  Securities  Act of 1933.  We will provide to you, as
soon as practicable, a copy of the required prospectus supplements necessary for
you to discharge  your  obligations  under section 5(b) of the Securities Act of
1933. In addition, we will file a Form 8-K upon completion of this transaction.

     Please note that this  agreement is subject to review by the American Stock
Exchange.
