                               PROSPECTUS SUMMARY

                            FALCONSTOR SOFTWARE, INC.

            We are a provider of storage networking infrastructure software. Our
open software  approach to storage  networking  enables companies to capture and
manipulate  the  expanding  volume  of  enterprise  data  and  existing  storage
solutions,   without   rendering  those  solutions   obsolete.   By  moving  the
"intelligence"  of  storage  management  from  hardware  to  software,  we allow
companies  to adopt  Fibre  Channel  technology  while  maximizing  their  prior
investments in Ethernet information technology, or IT, infrastructure and taking
full advantage of the ubiquitous connectivity of the industry-standard  internet
protocol,   or  IP.  Our  software   technology  can  rapidly   embrace  various
input/output, or I/O, interface, communications standards and innovative storage
services as they are  introduced.  Our flagship IPStor product began shipping in
May  2001.  IPStor  is  a  storage  solution  that  combines   industry-standard
connectivity  with  next-generation  network storage  services,  offering large,
widely-dispersed   enterprises  a  complete  storage  management  solution  that
includes  all  four  of  the  key  service  categories:  universal  connectivity
supporting  both  Fibre  Channel  and   IP/iSCSI-based   storage   provisioning,
virtualization;  storage services such as fail-over, mirroring,  replication and
snapshot,  and  unified  storage  area  network,  or SAN,  and  network-attached
storage, or NAS. Our commitment to open standards and universal connectivity has
been endorsed by industry leaders such as Adaptec,  Cisco,  Crossroads,  Emulex,
Gadzoox, IBM, NEC and QLogic.

                                CORPORATE HISTORY

            Network  Peripherals  Inc. was  incorporated  in California in March
1989  and  was  reincorporated  in  Delaware  in  1994.  FalconStor,   Inc.  was
incorporated in Delaware in February 2000.

            On August 22, 2001, we  consummated  an Agreement and Plan of Merger
and Reorganization  between us,  FalconStor,  Inc., and Empire Acquisition Corp.
whereby the  stockholders  of  FalconStor,  Inc.  received  our common  stock in
exchange for the shares or FalconStor capital stock they owned, and our name was
changed from Network Peripherals Inc. to FalconStor  Software,  Inc. Although we
acquired   FalconStor,   Inc.  as  a  result  of  the  transaction,   FalconStor
stockholders hold a majority of the voting interests in the combined enterprise.
Accordingly,   for  accounting   purposes,   the   acquisition  was  a  "reverse
acquisition" and FalconStor was the "accounting  acquiror." Further, as a result
of Network  Peripherals  Inc.'s  decision to  discontinue  its NuWave and legacy
business,  Network Peripherals Inc. became a non-operating  public shell with no
continuing  operations,   and  no  intangible  assets  associated  with  Network
Peripherals Inc. were purchased by FalconStor, Inc. Accordingly, the transaction
will be accounted for as a recapitalization  of FalconStor and recorded based on
the fair value of Network  Peripherals  Inc.'s net tangible  assets  acquired by
FalconStor, with no goodwill or other intangible assets being recognized.  Costs
incurred by FalconStor  directly  related to the transaction  will be charged to
stockholders'  equity. For further information relating to the transaction,  see
our proxy statement for special meeting of stockholders  held on August 22, 2001
and our Current Report on Form 8-K, dated September 6, 2001.

            Our  principal  executive  offices are  located at 125 Baylis  Road,
Melville, New York 11747. Our telephone number is (631) 777-5188.

                                  RISK FACTORS

            AN INVESTMENT IN THE SHARES  OFFERED BY THIS  PROSPECTUS  INVOLVES A
HIGH DEGREE OF RISK. YOU SHOULD  CAREFULLY  CONSIDER THE FOLLOWING RISK FACTORS,
AS  WELL  AS  INFORMATION  CONTAINED  AND  INCORPORATED  BY  REFERENCE  IN  THIS
PROSPECTUS BEFORE DECIDING TO INVEST IN OUR COMMON STOCK.

FAILURE OF THE MERGER TO ACHIEVE POTENTIAL  BENEFITS COULD HARM OUR BUSINESS AND
OPERATING RESULTS.

            We expect that the merger will result in potential  benefits for us.
Achieving these potential  benefits will depend on a number of factors,  some of
which include:

            o   retention of key management,  marketing and technical  personnel
                after the merger;

            o   our ability to increase  our  customer  base and to increase the
                sales of our products; and

            o   competitive conditions in the storage networking  infrastructure
                software market.

            We cannot assure you that the anticipated benefits will be achieved.
The failure to achieve anticipated  benefits could harm our business,  financial
condition and operating results.

WE HAVE HAD LIMITED REVENUES AND A HISTORY OF LOSSES,  AND WE MAY NOT ACHIEVE OR
MAINTAIN PROFITABILITY.

            We were incorporated on February 10, 2000. Due to the early stage of
our  product,  we have had  limited  revenues  and a history of losses.  For the
period from inception  (February 10, 2000) through June 30, 2001, we had a gross
loss of  $592,169  and a net  loss  of  $9,456,311.  We  currently  have  signed
contracts with resellers and original equipment manufacturers,  or OEMs, to ship
our products and expect that as a result of these  contracts,  our revenues will
increase in the future.  Our business model depends upon signing agreements with
additional OEM customers, developing a reseller sales channel, and expanding our
direct sales force. Any difficulty in obtaining these OEM and reseller customers
or in attracting  qualified sales personnel will negatively impact our financial
performance.

NETWORK PERIPHERALS INC. MAY HAVE LIABILITIES AND ONGOING OBLIGATIONS TO CERTAIN
CUSTOMERS AND SUPPLIERS AS A RESULT OF THE WINDING DOWN OF ITS BUSINESS.

            Network  Peripherals  Inc.  had  existing  agreements  with  certain
suppliers  and  customers,  which  we are  in  the  process  of  terminating  in
connection with the winding down of that business.  NPI may have  liabilities to
certain existing customers and suppliers as a result of the termination of these
agreements.  While we are taking steps to minimize any such potential liability,
we  cannot  be sure  that our  efforts  to  remove  all such  liability  will be
successful.

THE MARKET FOR IP-BASED STORAGE SOLUTIONS IS NEW AND UNCERTAIN, AND OUR BUSINESS
WILL SUFFER IF IT DOES NOT DEVELOP AS WE EXPECT.

            The rapid adoption of Internet protocol (IP)-based storage solutions
is critical to our future  success.  The market for IP-based  solutions is still
unproven,  making it difficult to predict its  potential  size or future  growth
rate, and there are currently only a handful of companies with IP-based  storage
products that are  commercially  available.  Most potential  customers have made
substantial investments in their current storage networking infrastructure,  and
they may elect to remain  with  current  network  architectures  or to adopt new
architecture,  in limited stages or over extended  periods of time. We will need
to convince these  potential  customers of the benefits of our IP-based  storage
products for future storage network  infrastructure  upgrades or expansions.  We
cannot be certain  that a viable  market  for our  products  will  develop or be

                                       5



sustainable.  If this market does not develop,  or develops  more slowly than we
expect,  our business,  financial  condition and results of operations  would be
seriously harmed.

IF WE ARE UNABLE TO DEVELOP AND MANUFACTURE NEW PRODUCTS THAT ADDRESS ADDITIONAL
STORAGE  NETWORKING  INFRASTRUCTURE  SOFTWARE  MARKET  SEGMENTS,  OUR  OPERATING
RESULTS MAY SUFFER.

            Although  our  current  products  are  designed  for one of the most
significant segments of the storage networking  infrastructure  software market,
demand may shift to other market segments.  Accordingly,  we may need to develop
and  manufacture  new  products  that  address   additional  storage  networking
infrastructure  software  market  segments and emerging  technologies  to remain
competitive in the data storage software industry.  We cannot assure you that we
will  successfully  qualify  new  storage  networking   infrastructure  software
products  with  our  customers  by  meeting  customer  performance  and  quality
specifications or quickly achieve high volume  production of storage  networking
infrastructure software products.

            Any failure to address  additional  market  segments  could harm our
business, financial condition and operating results.

OUR COMPLEX  PRODUCTS  MAY HAVE ERRORS OR DEFECTS  THAT COULD  RESULT IN REDUCED
DEMAND FOR OUR PRODUCTS OR COSTLY LITIGATION.

            Our IPStor  platform is complex and designed to be deployed in large
and complex  networks.  Many of our customers  will require that our products be
designed to interface with customers' existing networks,  each of which may have
different  specifications and utilize multiple protocol  standards.  Because our
products  are  critical  to the  networks  of  our  customers,  any  significant
interruption  in their service as a result of defects in our product  within our
customers'  networks  could result in lost  profits or damage to our  customers.
These problems could cause us to incur  significant  service and warranty costs,
divert engineering  personnel from product development efforts and significantly
impair our ability to maintain existing  customer  relationships and attract new
customers.  In addition,  a product liability claim,  whether successful or not,
would  likely be time  consuming  and  expensive  to  resolve  and would  divert
management  time and attention.  Further,  if we are unable to fix the errors or
other  problems  that may be  identified  in full  deployment,  we would  likely
experience  loss of or  delay  in  revenues  and loss of  market  share  and our
business and prospects would suffer.

THROUGH  JUNE  30,  2001,  WE  RECEIVED  49% OF  OUR  REVENUES  FROM A  ONE-TIME
CONSULTING  FEE AND A MAJORITY OF OUR FUTURE  REVENUES  MAY BE DERIVED FROM OEMS
AND RESELLERS.

            From inception through June 30, 2001, one customer, Depository Trust
Company,  accounted for 49% of our revenues. Such revenues related to a one-time
consulting  fee,  and we do not expect that we will realize  significant  future
revenues from this customer or from consulting services.  Our management expects
that the expansion of the end user base through OEMs and resellers  will account
for a significant  portion of our revenue.  We presently have  approximately  43
signed  contracts  with  OEMs  and  resellers.  These  contracts  are  generally
terminable upon 30 to 60 days' notice and OEMs and resellers have a wide variety
of suppliers to choose from and therefore could make substantial  demands on the
Company.  If we lose a key customer or if any of our key customers  reduce their
orders of our products or require us to reduce our prices  before we are able to
reduce costs,  our  business,  financial  condition and operating  results would
suffer.

                                       6



OUR QUARTERLY RESULTS MAY FLUCTUATE  SIGNIFICANTLY,  WHICH COULD CAUSE OUR STOCK
PRICE TO DECLINE.

            Our future performance will depend on many factors, including:

            o    the average unit selling price of our products;

            o    existing  or new  competitors  introducing  better  products at
                 competitive prices before we do;

            o    our ability to manage  successfully  the complex and  difficult
                 process of qualifying our products with our customers;

            o    our customers canceling,  rescheduling or deferring significant
                 orders for our products,  particularly  in  anticipation of new
                 products or enhancements from us or our competitors;

            o    import or export  restrictions on our  proprietary  technology;
                 and

            o    personnel changes.

            Many of our expenses are relatively fixed and difficult to reduce or
modify.  As a result,  the fixed nature of our expenses will magnify any adverse
effect of a decrease in revenue on our operating results.

THE STORAGE NETWORKING  INFRASTRUCTURE SOFTWARE MARKET IS HIGHLY COMPETITIVE AND
INTENSE COMPETITION COULD NEGATIVELY IMPACT OUR BUSINESS.

            The storage networking  infrastructure  software market is intensely
competitive even during periods when demand is stable.  Our management  believes
that we compete  primarily with DataCore and StorageApps.  Those competitors and
other potential  competitors may be able to establish  rapidly or expand storage
networking   infrastructure  software  offerings  more  quickly,  adapt  to  new
technologies and customer  requirements faster and take advantage of acquisition
and other opportunities more readily.

            Our competitors also may:

            o    consolidate   or  establish   strategic   relationships   among
                 themselves to lower their product costs or to otherwise compete
                 more effectively against us; or

            o    bundle their  products with other  products to increase  demand
                 for their products.

            In  addition,  some  OEMs with  whom we do  business,  or hope to do
business,  may enter the market directly and rapidly capture market share. If we
fail  to  compete  successfully  against  current  or  future  competitors,  our
business, financial condition and operating results may suffer.

THE LOSS OF ANY OF OUR KEY PERSONNEL COULD HARM OUR BUSINESS.

            Our success  depends  upon the  continued  contributions  of our key
employees,  many of whom would be extremely difficult to replace. We do not have
key person life insurance on any of our personnel. Many of our senior management
and a significant  number of our other  employees  have been with us for a short
period of time.  Worldwide  competition  for  skilled  employees  in the storage
networking  infrastructure  software  industry is extremely  intense.  If we are
unable to retain existing employees or to hire and integrate new employees,  our
business,  financial  condition and operating results could suffer. In addition,
companies whose employees accept positions with competitors often claim that the
competitors  have engaged in unfair hiring  practices.  We may be the subject of
such claims in the future as we seek to hire qualified personnel and could incur
substantial costs defending ourself against those claims.

OUR BOARD OF  DIRECTORS  MAY  SELECTIVELY  RELEASE  SHARES OF OUR  COMMON  STOCK
RECEIVED BY THE FORMER FALCONSTOR, INC. STOCKHOLDERS FROM LOCK-UP RESTRICTIONS.

            Our board of directors may, in its sole  discretion,  release any or
all  of the  shares  of our  common  stock  received  by the  former  FalconStor
stockholders from lock-up  restrictions at any time with or without notice.  Any
release of such shares from  lock-up  restrictions  may be applied to our former
stockholders  on  a  proportionate   or  selective  basis.  If  the  release  is
selectively  applied,  the  stockholders  whose shares are not released  will be
forced to hold such shares while other  stockholders may sell. In addition,  the
release of any of such shares could depress our stock price.

IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY, OUR BUSINESS WILL SUFFER.

            Our success is dependent upon our proprietary technology. Currently,
the IPStor  software suite is the core of our  proprietary  technology.  We have
three pending patent applications and pending trademark  applications related to
our IPStor  product.  We cannot predict  whether we will receive patents for our
pending or future patent  applications,  and any patents that we own or that are
issued to us may be invalidated,  circumvented or challenged.  In addition,  the
laws of  certain  countries  in  which  we sell and  manufacture  our  products,
including   various  countries  in  Asia,  may  not  protect  our  products  and
intellectual  property  rights  to the same  extent  as the  laws of the  United
States.

            We also rely on trade secret,  copyright and trademark laws, as well
as the confidentiality and other restrictions  contained in our respective sales
contracts  and  confidentiality  agreements to protect our  proprietary  rights.
These legal protections afford only limited protection.

OUR  TECHNOLOGY  MAY BE  SUBJECT  TO  INFRINGEMENT  CLAIMS  THAT  COULD HARM OUR
BUSINESS.

            We may become subject to litigation  regarding  infringement  claims
alleged by third  parties.  We have received  correspondence  from a third party
claiming  that some of our employees  formerly  employed by that third party may
have  disclosed  proprietary  information  of the third  party in  violation  of
certain  agreements or other  obligations to that third party.  This third party
has also asserted that our intellectual property may be based on or utilizes its
intellectual property. As of the date of this registration  statement, no formal
action has been taken by the third  party.  We believe  these claims are without
merit. However, if an action is commenced against us, our management may have to
devote   substantial   attention  and  resources  to  defend  these  claims.  An
unfavorable  result for the Company could have a material  adverse effect on our
business,  financial  condition and operating and could limit our ability to use
our intellectual property.

WE HAVE A SIGNIFICANT  AMOUNT OF AUTHORIZED BUT UNISSUED  PREFERRED STOCK, WHICH
MAY AFFECT THE LIKELIHOOD OF A CHANGE OF CONTROL IN OUR COMPANY.

            Our Board of Directors has the authority,  without further action by
the  stockholders,  to issue up to 2,000,000  shares of preferred  stock on such
terms and with such rights,  preferences and  designations,  including,  without
limitation  restricting  dividends on our common  stock,  dilution of the voting
power of our common stock and impairing the liquidation rights of the holders of
our  common  stock,  as  the  Board  may  determine  without  any  vote  of  the
stockholders.  Issuance  of such  preferred  stock,  depending  upon the rights,
preferences and designations thereof may have the effect of delaying,  deterring
or  preventing  a  change  in  control.  In  addition,  certain  "anti-takeover"
provisions of the Delaware  General  Corporation  Law,  among other things,  may
restrict  the  ability  of our  stockholders  to  authorize  a merger,  business
combination or change of control.

                                       8



WE HAVE A SIGNIFICANT NUMBER OF OUTSTANDING OPTIONS, THE EXERCISE OF WHICH WOULD
DILUTE THE THEN-EXISTING STOCKHOLDERS' PERCENTAGE OWNERSHIP OF OUR COMMON STOCK.

            As of September 3, 2001, we have outstanding  options to purchase an
aggregate of 7,473,372 shares of our common stock at a weighted average exercise
price of $3.97 per share.

            The  exercise of all of the  outstanding  options  would  dilute the
then-existing  stockholders' percentage ownership of common stock, and any sales
in the public  market of the common  stock  issuable  upon such  exercise  could
adversely affect prevailing market prices for the common stock. In addition, the
existence of a significant  amount of  outstanding  options may encourage  short
selling by the option  holders  since the  exercise of the  outstanding  options
could depress the price of our common stock.  Moreover,  the terms upon which we
would be able to obtain  additional  equity capital could be adversely  affected
because  the holders of such  securities  can be expected to exercise or convert
them at a time when we would,  in all  likelihood,  be able to obtain any needed
capital on terms more favorable than those provided by such securities.

                                 USE OF PROCEEDS

            The shares of Common Stock offered  hereby are being  registered for
the account of the  selling  stockholders  identified  in this  prospectus.  See
"Selling  Stockholders." All net proceeds from the sale of the Common Stock will
go to the stockholders who offer and sell their shares.  We will not receive any
part of the proceeds from such sales of Common Stock.

                             ADDITIONAL INFORMATION

            We have filed  with the  Securities  and  Exchange  Commission  (the

             The selling  stockholders  may effect such  transactions by selling
shares to or through  broker-dealers,  and all such  broker-dealers  may receive
compensation  in the form of discounts,  concessions,  or  commissions  from the
selling  stockholders  and/or the  purchasers of shares of Common Stock for whom
such  broker-dealers  may act as agents or to whom they sell as  principals,  or
both (which compensation as to a particular  broker-dealer might be in excess of
customary commissions).

             Any   broker-dealer   acquiring   Common  Stock  from  the  selling
stockholders  may sell the shares either directly,  in its normal  market-making
activities, through or to other brokers on a principal or agency basis or to its
customers. Any such sales may be at prices then prevailing on the American Stock
Exchange or at prices related to such prevailing  market prices or at negotiated
prices  to  its  customers  or  a  combination  of  such  methods.  The  selling
stockholders and any broker-dealers  that act in connection with the sale of the
Common Stock hereunder might be deemed to be  "underwriters"  within the meaning
of Section 2(11) of the Securities Act; any commissions received by them and any
profit on the resale of shares as principal  might be deemed to be  underwriting
discounts and  commissions  under the Securities Act. Any such  commissions,  as
well as other  expenses  incurred by the  selling  stockholders  and  applicable
transfer taxes, are payable by the selling stockholders.

             The selling  stockholders reserve the right to accept, and together
with any  agent of the  selling  stockholder,  to reject in whole or in part any
proposed  purchase of the shares of Common Stock. The selling  stockholders will
pay any sales  commissions  or other  seller's  compensation  applicable to such
transactions.

             We have not  registered or qualified  offers and sales of shares of
the Common Stock under the laws of any country other than the United States.  To
comply  with  certain  states'  securities  laws,  if  applicable,  the  selling
stockholders  will  offer  and  sell  their  shares  of  Common  Stock  in  such
jurisdictions  only  through  registered  or  licensed  brokers or  dealers.  In
addition,  in certain  states  the  selling  stockholders  may not offer or sell
shares of Common Stock unless we have  registered  or qualified  such shares for
sale in such  states  or we have  complied  with  an  available  exemption  from
registration or qualification.

                                       17



             The selling  shareholders  have represented to us that any purchase
or sale of  shares  of  Common  Stock by them  will  comply  with  Regulation  M
promulgated under the Securities  Exchange Act of 1934, as amended.  In general,
Rule 102 under  Regulation M prohibits any person  connected with a distribution
of securities (the  "Distribution")  from directly or indirectly bidding for, or
purchasing for any account in which he or she has a beneficial interest,  any of
such  securities or any right to purchase such  securities,  for a period of one
business  day before and after  completion  of his or her  participation  in the
distribution (we refer to that time period as the "Distribution Period").

             During  the  Distribution  Period,  Rule  104  under  Regulation  M
prohibits  the  selling  stockholders  and  any  other  persons  engaged  in the
Distribution  from engaging in any  stabilizing  bid or purchasing of our Common
Stock  except for the purpose of  preventing  or retarding a decline in the open
market  price of our Common  Stock.  No such  person may effect any  stabilizing
transaction  to facilitate  any offering at the market.  Inasmuch as the selling
shareholders  will be  reoffering  and reselling our Common Stock at the market,
Rule  104  prohibits  them  from  effecting  any   stabilizing   transaction  in
contravention of Rule 104 with respect to our Common Stock.

             There can be no assurance that the selling  stockholders  will sell
any or all of the shares offered by them hereunder or otherwise.

                                  LEGAL MATTERS

               Total..........................................        $85,000

Item 15.    Indemnification of Directors and Officers.

            As permitted by the Delaware General  Corporation Law ("DGCL"),  the
Company's  Certificate  of  Incorporation,   as  amended,  limits  the  personal
liability  of a director  or officer to the  Company  for  monetary  damages for
breach of fiduciary duty of care as a director.  Liability is not eliminated for
(i)  any  breach  of the  director's  duty  of  loyalty  to the  Company  or its
stockholders,  (ii)  acts  or  omissions  not in good  faith  or  which  involve
intentional  misconduct or a knowing violation of law, (iii) unlawful payment of
dividends or stock purchase or redemptions  pursuant to Section 174 of the DGCL,
or (iv) any  transaction  from which the director  derived an improper  personal
benefit.

            The Company has also entered into  indemnification  agreements  with
each of its directors and executive  officers.  The  indemnification  agreements
provide that the  directors and executive  officers will be  indemnified  to the
fullest  extent  permitted by  applicable  law against all  expenses  (including
attorneys' fees),  judgments,  fines and amounts  reasonably paid or incurred by
them for  settlement in any  threatened,  pending or completed  action,  suit or
proceeding,  including any derivative  action, on account of their services as a
director or officer of the Company or of any subsidiary of the Company or of any
other  company or  enterprise  in which they are  serving at the  request of the
Company.   No  indemnification   will  be  provided  under  the  indemnification
agreements,  however,  to any director or executive  officer in certain  limited
circumstances,  including  on  account  of  knowingly  fraudulent,  deliberately
dishonest  or  willful   misconduct.   To  the  extent  the  provisions  of  the
indemnification  agreements exceed the  indemnification  permitted by applicable
law, such  provision may be  unenforceable  or may be limited to the extent they
are found by a court of competent jurisdiction to be contrary to pubic policy.

DELAWARE LAW

            The Company is subject to Section 203 of the DGCL, which prevents an
"interested  stockholder" (defined in Section 203, generally, as a person owning
15% or more of a  corporation's  outstanding  voting  stock) from  engaging in a
"business combination" with a publicly-held Delaware corporation for three years
following  the date such person became an interested  stockholder,  unless:  (i)
before such person became an interested  stockholder,  the board of directors of
the  corporation  approved the  transaction in which the interested  stockholder
became an interested stockholder or approved the business combination; (ii) upon
consummation  of the transaction  that resulted in the interested  stockholder's
becoming an interested stockholder, the interested stockholder owns at least 85%
of the voting stock of the  corporation  outstanding at the time the transaction
commenced (subject to certain exceptions), or (iii) following the transaction in
which such person became an interested stockholder,  the business combination is

                                      II-1



approved  by the board of  directors  of the  corporation  and  authorized  at a
meeting of  stockholders  by the  affirmative  vote of the holders of 66% of the
outstanding  voting  stock  of the  corporation  not  owned  by  the  interested
stockholder. A "business combination" includes mergers, stock or asset sales and
other   transactions   resulting  in  a  financial  benefit  to  the  interested
stockholder.

            The  provisions  of Section 203 of the DGCL could have the effect of
delaying, deferring or preventing a change in the control of the Company.

Item 16.    Exhibits.

            Exhibit Index

       5        Opinion of Olshan  Grundman Frome  Rosenzweig & Wolosky LLP with
                respect to the securities registered hereunder.

       23.1     Consent of KPMG LLP.

       23.2     Consent of PricewaterhouseCoopers LLP.

       23.3     Consent  of Olshan  Grundman  Frome  Rosenzweig  &  Wolosky  LLP
                (included within Exhibit 5).

       24.1     Powers  of  Attorney  (included  on the  Signature  page  to the
                Registration Statement).

Item 17.    Undertakings.

            The undersigned registrant hereby undertakes:

(1)         To file,  during any period in which offers or sales are being made,
            a post-effective amendment to this registration statement to include
            any material  information  with respect to the plan of  distribution
            not  previously  disclosed  in  the  registration  statement  or any
            material change to such information in the registration statement.

(2)         That,  for the  purpose  of  determining  any  liability  under  the
            Securities Act of 1933, each such post-effective  amendment shall be
            deemed to be a new registration statement relating to the securities
            offered  therein,  and the offering of such  securities at that time
            shall be deemed to be the initial bona fide offering thereof.

(3)         To remove from  registration by means of a post-effective  amendment
            any of the  securities  being  registered  that remain unsold at the
            termination of the offering.

            The undersigned  registrant  hereby undertakes that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

            Insofar  as  indemnification   for  liabilities  arising  under  the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the registrant  pursuant to the foregoing  provisions,  or otherwise,

                                      II-2



the  registrant  has been  advised  that in the  opinion of the  Securities  and
Exchange  Commission such  indemnification is against public policy as expressed
in the Act and is,  therefore,  unenforceable.  In the  event  that a claim  for
indemnification  against  each such  liabilities  (other than the payment by the
registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
