            The following  constitutes Amendment No. 1 to the Schedule 13D filed
by the undersigned (the "Schedule 13D"). Except as specifically  amended by this
Amendment No. 1, the Schedule 13D remains in full force and effect.  Capitalized
terms used in this  Amendment No.1 but not defined herein shall have the meaning
set forth in the Schedule 13D.


            Item 6 is amended in its entirety to read as follows:

Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect to
         -------------------------------------------------------------------------
         Securities of the Issuer.
         -------------------------

            Prior to the Merger, the Reporting Person and the other stockholders
of the  Issuer who  received  shares of Common  Stock in the  Merger  executed a
lock-up agreement (the "Lock-Up  Agreement") which provided that the sale of the
shares of Common  Stock they  acquired in the Merger  were  subject to a lock-up
until August 22, 2002. In January 2002,  certain of the stockholders  subject to
the Lock-up  Agreement,  including the Reporting Person,  agreed to extend their
lock-up until April 30, 2003 (the "Extended  Lock-Up").  In connection  with the
Extended  Lock-Up,  the Board of  Directors  obtained  the  approval  of certain
principal  stockholders  of the Issuer,  including the Reporting  Person,  Barry
Fingerhut,  Marilyn  Rubenstein,  Irwin Lieber,  Barry  Rubenstein,  and certain
investment  partnerships  affiliated  with  Messrs.  Lieber and  Rubenstein  who
directly  own shares of Common  Stock being Seneca  Ventures,  Woodland  Venture
Fund,  Woodland Partners,  Wheatley Partners,  L.P.,  Wheatley Foreign Partners,
L.P.,  Wheatley Partners II, L.P.,  Wheatley Partners III, L.P., Whatley Foreign
Partners  III,  L.P.,  and Wheatley  Associates  III,  L.P.  (collectively,  the
"Principal  Stockholders")  to  provide  that in the  event  that  the  Board of
Directors  releases  shares of Common Stock from the Lock-Up  Agreement prior to
April 30, 2003, that the shares held by the Principal  Stockholders  will not be
released from the Lock-Up Agreement until all other stockholders  subject to the
Lock-Up  Agreement have been given the opportunity to elect to have all of their
shares of Common Stock subject to the Lock-Up  Agreement  released by the Issuer
for sale.  No shares of Common  Stock  owned by the  Reporting  Person  has been
released from the Lock-Up Agreement.


            Item 7 is amended to include the following:

Item 7.  Materials to be Filed as Exhibits.
         ---------------------------------


            The following documents are filed herewith:

                   FALCONSTOR SOFTWARE, INC. LOCK-UP AGREEMENT





As of January 7, 2002


Stockholder



To Whom It May Concern:


            Pursuant  to an  Agreement  and Plan of Merger  and  Reorganization,
dated as of May 4, 2001 (the  "Agreement"),  Empire  Acquisition Corp., a wholly
owned  subsidiary  of Network  Peripherals  Inc.  ("NPI"),  merged with and into
FalconStor,  Inc. (the "Merger"),  with the surviving  entity called  FalconStor
Software, Inc. (the "Company").  To induce NPI to enter into the Agreement,  the
undersigned,  during the period  that  commenced  on August 22, 2001 and ends on
August 22, 2002 (the "Lock-Up Period"):

                  (i) agreed not to, directly or indirectly sell, offer to sell,
            contract to sell (including,  without  limitation,  any short sale),
            grant any option to  purchase  or  otherwise  transfer or dispose of
            (other  than  to  donees  who  agree  to  be  similarly  bound)  any
            securities  received  by the  undersigned  in  connection  with  the
            Merger; and

                  (ii)   acknowledged   that  following  August  22,  2001,  the
            Company's  Board of Directors may, in its sole  discretion,  release
            any  or  all  of  the  shares  held  by  the  undersigned  from  the
            obligations  of this letter prior to the  expiration  of the Lock-Up
            Period.


            As set forth in the attached letter, the Board of Directors believes
it would be beneficial for all  stockholders  to extend the Lock-Up Period until
April 30, 2003. By executing this letter, you agree to extend the Lock-Up Period
(the  "Lock-Up   Extension")  until  and  including  April  30,  2003,  and  you
acknowledge the beneficial benefits to you of this extension.

            Furthermore, the Lock-Up Extension will not be effective unless 100%
of all  stockholders  subject  to the  Lock-Up  Period  agree to the  extension.
Finally, in order to facilitate an orderly sale of stock subject to the lock-up,
if the Board of Directors decides to release any shares before the expiration of
the Lock-Up Extension, the undersigned will be required and agrees to use either
HD Brous &  Co., Inc.,  Ladenberg,  Thalman & Co., Inc., Wien Securities
Corp. or Janney  Montgomery  Scott LLC, as the undersigned  indicates below. You
can sell  shares  though  such  brokers  during the  limited  time period of the
release.  Any release of shares not sold during such period shall remain subject
to the Lock-Up Extension.

            The undersigned  hereby represents and warrants that the undersigned
has full power and authority to execute this letter and enter the agreements set
forth  herein,  and  that,  upon  request,  the  undersigned  will  execute  any
additional  documents  necessary or desirable in connection with the enforcement
hereof.

undersigned  shall  be  binding  upon  the  heirs,   personal   representatives,
