                                 THE COMPANY

      Excalibur  Technologies  Corporation  ("Excalibur")  is a  leader  in  the
development  and  sale  of  software   solutions  for   information   retrieval.
Excalibur's software products combine two complementary  technologies:  Adaptive
Pattern Recognition  Processing  (APRP(TM)) and semantic networks.  The APRP(TM)
technology  identifies  and indexes the  underlying  binary  patterns in digital
data, providing the capability to build content-based retrieval applications for
any type of digital  information,  including  text,  images,  video and  sounds.
Semantic  networks leverage lexical  knowledge,  offering a system with build-in
knowledgebases  to search for specific word  meanings  enriched by related terms
and concepts. Integration of these two approaches provides complete and powerful
information  retrieval  capabilities  with accuracy and speed.  Excalibur's core
technologies   enable   high   fault-tolerant   fuzzy   searching   and  natural
language-based  searching  for  text,  as  well  as  powerful   query-by-example
capabilities which can be applied to words, pictures, video clips, fingerprints,
facial images and many other types of multi-media data.

      Using these technologies, Excalibur has developed a comprehensive suite of
information  retrieval  software  products,  including  libraries,  services and
applications,  called  RetrievalWare.  RetrievalWare  is  a  unified  family  of
applications  and software  components for building  retrieval  solutions across
multiple information types. Its flexible and modular  architecture  supports the
full range of Excalibur  development  tools for value added resellers  ("VARs"),
original  equipment  manufacturers  ("OEMs"),  systems  integrators  ("SIs") and
corporate  and  government  information  technology   departments.   Excalibur's
RetrievalWare is a complete software component architecture, enabling developers
to build  information  retrieval  applications  for workgroup,  enterprises  and
across  the  internet.  RetrievalWare  platforms  include  all  major  UNIX  and
Windows/NT servers, with PC and UNIX clients.

      In July 1995, Excalibur acquired ConQuest Software,  Inc. ("ConQuest"),  a
private  company  located in  Columbia,  Maryland,  engaged in the  business  of
providing natural language text management software tools,  through the issuance
of  approximately  1,427,000  restricted  shares of  Excalibur  common stock and
options to purchase  approximately 572,000 restricted shares of Excalibur common
stock to the former ConQuest shareholders and option holders in exchange for all
of the outstanding common stock of ConQuest.  The transaction has been accounted
for as a pooling of interests.  The  consolidated  results of operations and the
discussion thereof that are presented herein reflect the combined results of the
pooled business for the respective periods presented.

      The Company established a wholly-owned  subsidiary in the United  Kingdom,
Excalibur Technologies  International,  Ltd. ("ETIL"), which began operations in
July 1992. Except as otherwise noted, Excalibur, ConQuest (the acquired company)
and ETIL are collectively referred to hereinafter as the "Company."

      The Company markets and distributes its products  through VARs, SIs, OEMs,
direct sales, distribution agreements, and a marketing agreement with IBM. As of
January 31, 1996,  more than 600 customers were using the Company's  information
retrieval products.


                                   - 5 -






      Excalibur  was   incorporated  on  February  11,  1980  as  a  New  Mexico
corporation and reincorporated on September 26, 1989 as a Delaware  corporation.
The  Company's  principal  executive  offices are located at 1921 Gallows  Road,
Suite 200, Vienna, Virginia 22182, telephone (703) 761-3700.

                                 RISK FACTORS

      A prospective  investor should  carefully  consider all of the information
contained in this Prospectus and, in particular, the following:

      Marketing  Acceptance of Products and  Historical  Operating  Losses.  The
Company  believes  that its future  profitability  will depend on its ability to
effectively  market existing and  newly-developed  software  products  through a
balanced multi-channel  distribution network. There can be no assurance that the
expenses incurred in connection with the development, introduction and promotion
of enhanced or new products will not exceed the Company's expectations,  or that
these products will generate revenues  sufficient to offset these expenses.  The
Company has operated at a loss for the most recent  fiscal  quarter and for each
of the past three fiscal years. The Company reported a net loss of $1,725,000 on
revenues of  approximately  $4,001,000  for its fiscal  quarter  ended April 30,
1996. The Company reported a net loss of  approximately  $884,000 on revenues of
approximately $18,675,000 for the fiscal year ended January 31, 1996, a net loss
of  approximately  $9,388,000 on revenues of  approximately  $12,638,000 for the
fiscal year ended January 31, 1995 and a net loss of approximately $8,319,000 on
revenues of  approximately  $12,285,000  for the fiscal  year ended  January 31,
1994. These losses reflect the Company's expenditures associated with building a
marketing  organization to sell software  products released in 1994 and 1995 and
further  developing  software  products  during  such years.  The  Company  will
continue to invest in these  programs  and,  accordingly,  operating  losses may
continue for at least the next 12 months.

      Relationship  with IBM. In July and August 1993, the Company  entered into
Cooperative  Marketing Agreements with IBM under which IBM made guaranteed sales
commitments to the Company for fiscal 1994 and fiscal 1995.  Revenues from sales
generated by IBM in fiscal years 1996, 1995 and 1994 represented 2%, 12% and 7%,
respectively,  of total revenues.  A decision by IBM to limit or discontinue its
relationship  with the Company could result in a significant  loss of revenue to
the Company.

      Lack of Patent Protection.  The Company has not obtained patents on any of
its  technology.  The Company  regards its  software as  proprietary  and relies
primarily on a  combination  of  copyright,  trademark  and trade secret laws of
general  applicability,   employee   confidentiality  and  invention  assignment
agreements,  distribution  and OEM  software  protection  agreements  and  other
intellectual  property  protection  methods  to  safeguard  its  technology  and
software  products.  The  Company  also  relies  upon its  efforts to design and
produce new products,  and upon improvements to existing products, to maintain a
competitive  position in the marketplace.  The Company has no assurance that its
technology will remain proprietary.

      Competition.  Competition in the computer and  communications  industry in
general,  and the computer  software  industry in  particular,  is intense.  The
Company's   competitors  include  many  companies  which  are  larger  and  more
established and have substantially more resources than the Company.

                                   - 7 -






      Dependence  on Computer  Manufacturers.  The Company's  computer  software
products are designed to work specifically with manufacturers' computer systems;
however,  the Company has no agreement with the manufacturers of those computers
by which it may ensure that the  computers  will not be  redesigned  in a manner
incompatible with the Company's products.

      Dependence  on Key  Personnel.  The  Company's  business is  substantially
dependent upon the active participation and technical expertise of its executive
officers and key  personnel.  The  Company's  ability to maintain a  competitive
position in light of technological  developments  will depend, in large part, on
its ability to attract and retain highly qualified personnel, of which there can
be no assurance.  The Company has acquired $1 million life insurance policies on
the lives of each of Patrick  Condo,  its Chief  Executive  Officer and James W.
Dowe III, the Company's chief scientist.

      Voting  Control by  Principal  Shareholder.  Allen & Company  Incorporated
("Allen"),  certain  officers and  shareholders of Allen and certain persons who
might be  deemed  to be  related  persons  of Allen  together  beneficially  own
approximately  36.7% of the  outstanding  shares of Common Stock of the Company.
Accordingly,  Allen may be deemed to be an "affiliate" of the Company within the
meaning of the Securities  Act of 1933. As a result of such ownership  interest,
Allen and such other persons may be able to  effectively  control the outcome of
certain matters  requiring a shareholder  vote,  including offers to acquire the
Company and  election of  directors.  In addition,  Richard M. Crooks,  Jr., the
Chairman  of the  Board  of  Directors  of the  Company,  is a  director  of and
consultant to Allen.

      Authorization   of  Preferred   Stock.   The  Company's   Certificate   of
Incorporation  authorizes the issuance of one million shares of Preferred  Stock
with such designations, rights and preferences as may be determined from time to
time by the Company's Board of Directors. Accordingly, the Board of Directors is
empowered, without shareholder approval, to issue Preferred Stock with dividend,
liquidation, conversion, voting, or other rights that could adversely affect the
voting  power or other  rights of the  holders of the  Company's  Common  Stock.
Although the Company has no present intention of issuing any shares of Preferred
Stock,  it can give no  assurance  that it will  not  issue  Preferred  Stock in
future. See Description of Capital Stock - Preferred Stock".

      Certain  Anti-Takeover  Provisions.  Certain  provisions  of the Company's
Certificate of Incorporation, its Stock Option Plans and Delaware law could have
the effect,  either  alone or in  combination  with each  other,  of making more
difficult,  or discouraging an acquisition of the Company deemed  undesirable by
its Board of Directors.  Under the Company's  Certificate of Incorporation there
are approximately  4,464,000 unreserved shares of Common Stock and approximately
950,000  shares  of  Preferred  Stock  available  for  future  issuance  without
shareholder  approval  as of June 7,  1996.  The  existence  of  authorized  but
unissued  capital  stock,  together  with the  continued  voting  control of the
Company by Allen could have the foregoing  effect of discouraging an acquisition
of the  Company.  Under the  Company's  Stock  Option  Plans,  as  amended  (the
"Plans"),  in the  event of a  change  in  control,  stock  appreciation  rights
("SAR's")  and limited  SARs  outstanding  for at least six months and any stock
options which are not then exercisable will become fully exercisable and vested.


                                   - 8 -





The Plans may have the effect of significantly increasing the costs of acquiring
the Company in a hostile takeover.  The Company is subject to Section 203 of the
Delaware General Corporation Law, which prohibits a Delaware  corporation,  such
as the Company, from engaging in a wide range of specified transactions with any
person who becomes a 15% stockholder, under certain circumstances,  within three
years after such person became an "interested shareholder."

      Stock Options Outstanding. As of June 7, 1996, the Company had outstanding
stock  options to purchase an aggregate  of 2,497,283  shares of Common Stock at
exercise prices ranging from $1.04 to $29.64 per share. These options are likely
to be exercised,  if at all, at a time when the Company otherwise could obtain a
price for the sale of shares of Common  Stock  which is higher  than the  option
exercise price per share.  Such exercise or the possibility of such exercise may
impede the Company if it later seeks  financing  through the sale of  additional
securities.

      Future  Sales of Common  Stock.  Of the  Company's  shares of Common Stock
currently  outstanding,  a  substantial  number of such  shares are  "restricted
securities"  as that term is defined  under Rule 144 under the  Securities  Act,
which, under certain  circumstances,  may be sold without  registration with the
Commission  under the Securities  Act. An aggregate of  approximately  1,625,996
shares of the Company's  Common Stock subject to  exercisable  stock options are
presently  being  offered for sale under the Company's  registered  stock option
plan.  The Company is unable to predict  the effect  that sales of Common  Stock
made  under  Rule 144 or  pursuant  to the stock  options  described  above,  or
otherwise, may have on the then prevailing market price of Common Stock.

      Increased  Accounts  Receivable.  Total accounts  receivable  increased by
$47,000 in the three  months  ended April 30,  1996 to a balance of  $7,364,000.
Accounts  receivable  increased by approximately  $3,289,000,  or 80%, in fiscal
year 1996.  The  increases  were due to several  factors  including  the overall
increase  in the  Company's  revenues,  an  increase  in  the  amount  of  sales
negotiated  with  extended  customer  payment  terms,  and  an  increase  in the
percentage  of sales booked close to the end of the period.  The effect of these
factors has been to increase the amount of days sales  outstanding.  The average
days sales outstanding at April 30, 1996,  January 31, 1996 and January 31, 1995
were 138, 114 and 88, respectively.

      In the three month period ended April 30, 1996, the Company added $100,000
to the allowance for doubtful accounts.  Management  believes that the allowance
was  adequate at April 30,  1996.  However,  in the event that the Company  were
unable to collect its outstanding  accounts  receivable,  the amount of bad debt
expense could increase in the future.



                             PLAN OF DISTRIBUTION

            This Prospectus  relates to the sale by the Selling  Shareholders of
50,095 fully paid and  non-assessable  shares of the Company's Common Stock, par
value  $.01 per share.  The Shares may be sold from time to time by the  Selling
Shareholders in the over-the-counter  market at then  prevailing  market  prices

                                   - 9 -






or in privately negotiated transactions. Although the Company ultimately expects
that all 50,095  Shares may be sold,  the actual  number of Shares  that will be
sold cannot be determined.

      In offering the Shares, the Selling Shareholders and any selling broker or
dealer  may be deemed to be  statutory  "underwriters"  within  the  meaning  of
Section 2(11) of the Securities Act in connection with such sales.

      The Company has advised the Selling  Shareholders that they,  because they
may be deemed to be statutory  underwriters,  will be subject to the  Prospectus
delivery requirements under the Securities Act. The Company has also advised the
Selling Shareholders that in the event of a "distribution" of their shares, such
Selling  Shareholders,   any  selling  broker  or  dealer  and  any  "affiliated
purchasers"  may be subject to Rule 10b-6 under the  Securities  Exchange Act of
1934,  as  amended  (the  "Exchange  Act"),  until  its  participation  in  that
distribution is completed. A "distribution" is defined in Rule 10b-6(c)(5) as an
offering of securities "that is distinguished from ordinary trading transactions
by the magnitude of the offering and the presence of special selling efforts and
selling  methods."  The Company has also advised the Selling  Shareholders  that
Rule  10b-7  under  the  Exchange  Act  prohibits  any   "stabilizing   bid"  or
"stabilizing  purchase" for the purpose of pegging,  fixing or  stabilizing  the
price of Common Stock in connection with this offering.

      Any shares covered by this  Prospectus  which qualify for sale pursuant to
Rule 144 may be sold under Rule 144 rather than pursuant to this Prospectus.

      The  Company  will  pay all  the  expenses,  estimated  to be  $25,000  in
connection with this offering, other than underwriting commissions and discounts
and counsel fees and expenses of the Selling Shareholders.

                               USE OF PROCEEDS

      The Company will not receive any  proceeds  from the sale of the Shares by
the Selling Shareholders.


                                   DILUTION

      The net  tangible  book  value of the  Company  as of April  30,  1996 was
approximately  $22,075,000 or $1.79 per common share. Since the shares are being
offered by the Selling  Shareholders,  there is no increase in net tangible book
value per common share to existing  shareholders by virtue of the sale.  Without
taking into account any changes in net tangible  book value after April 30, 1996
or shares  issued after that date,  the Company had as of that date an aggregate
of  approximately  12,340,000  shares of  Common  Stock  outstanding  with a net
tangible  book  value of $1.79 per  share.  Assuming  a sale at the  anticipated
offering  price set forth below,  this will  represent an immediate  dilution of
$19.96 per share to new  shareholders.  The  following  table  illustrates  this
dilution per share:


                                   - 10 -

      The  calculations   above  do  not  take  into  account  the  exercise  of
outstanding  stock options.  On June 7, there were outstanding  stock options to
purchase an  aggregate of  2,497,283  shares of Common Stock at exercise  prices
ranging from $1.04 to $29.64 per share.  To the extent that these stock  options
are exercised, there will be further dilution to new shareholders.


(1)   Net tangible  book value per common share  represents  the amount of total
      tangible assets less total liabilities and preferred stock, divided by the
      number of shares of Common Stock outstanding at that date.

(2)   Dilution is determined by  subtracting  net tangible book value per common
      share after the  offering  from the amount paid by an investor for a share
      of Common Stock.

                             SELLING SHAREHOLDERS

      Excalibur  acquired  ConQuest  Software,  Inc.  on  July  20,  1995.  This

      The following table sets forth the number of shares of Common Stock of the
Company  beneficially  owned by the Selling  Shareholders  on June 7, 1996,  the
number of Shares  covered  by this  Prospectus  and the  amount  and  percentage
ownership  by the  Selling  Shareholder  after  the  offering.  All  shares  are
beneficially  owned  and the sole  voting  and  investment  power is held by the
person named. None of the Selling Shareholders has had any material relationship
with the Company  during the past three years other than the ownership of shares
of Common Stock.

                         DESCRIPTION OF CAPITAL STOCK

      The authorized  capital stock of the Company consists of 20,000,000 shares
of Common Stock,  par value $.01 per share,  and  1,000,000  shares of Preferred
Stock,  par value $.01 per share,  of which  49,587  shares  are  designated  as
Cumulative  Convertible  Preferred Stock. At June 7, 1996,  12,357,217 shares of
Common Stock were issued and  outstanding  and no shares of Preferred Stock were
issued or  outstanding,  except  for  27,180  shares of  Cumulative  Convertible
Preferred Stock.


Common Stock

      The  issued and  outstanding  shares of Common  Stock are,  and the Shares
being offered hereby by the Selling Shareholders are, validly issued, fully paid
and  non-assessable.  The  holders  of  outstanding  shares of Common  Stock are
entitled to receive dividends out of assets legally  available  therefor at such
times  and in such  amounts  as the  Board of  Directors  may from  time to time
determine.  The  Company has not paid any  dividends  and does not expect to pay
cash dividends on its Common Stock in the foreseeable future.

      All shares of Common  Stock have equal  voting  rights and,  when  validly
issued and outstanding,  have one vote per share in all matters to be voted upon
by the  shareholders.  Cumulative  voting in the  election of  directors  is not
allowed, which means that the holders of more than 50% of the outstanding shares
can elect all the  directors  if they choose to do so and,  in such  event,  the
holders of the remaining shares will not be able to elect any directors.


      The shares have no  pre-emptive,  subscription,  conversion  or redemption
rights. Upon liquidation,  dissolution or winding-up of the Company, the holders
of Common Stock are entitled to receive pro rata the assets of the Company which
are legally available for distribution to shareholders.

Preferred Stock

      The Board of Directors of the Company has the  authority to issue  950,413
shares of  Preferred  Stock in one or more  series  and to fix the  designation,
relative  powers,  preferences  and rights and  qualifications,  limitations  or
restrictions of all shares of each such series,  including,  without limitation,
dividend rates,  conversion rights,  voting rights,  redemption and sinking fund
provisions,  liquidation  preferences and the number of shares constituting each
such series, without any further vote or action by the shareholders. 

                                     - 16 -








      The Company's 49,587 shares of Cumulative  Convertible Preferred Stock, of
which 27,180 shares are outstanding, are convertible into shares of Common Stock
at the rate of ten shares of Common  Stock per share of  Cumulative  Convertible
Preferred  Stock.  Holders of the  Cumulative  Convertible  Preferred  Stock are
entitled to receive  cumulative  dividends at $0.50 per share per annum  payable
annually on April 1, if declared by the Board of Directors, in cash or shares of
Common Stock (to be determined  by the Board),  valued at the lower of $1.00 per
share or the market price on the date of declaration.  In the event of voluntary
liquidation,  dissolution or winding-up of the Company, or upon any distribution
of  assets,  whether  voluntary  or  involuntary,   holders  of  the  Cumulative
Convertible  Preferred  Stock would have a liquidation  preference of $10.00 per
share, plus accrued and unpaid dividends.

      The issuance of Preferred  Stock could decrease the amount of earnings and
assets available for distribution to holders of Common Stock or adversely affect
the rights and powers,  including voting rights,  of the holders of Common Stock
and could,  among  other  things,  have the  effect of  delaying,  deferring  or
preventing  a change in control of the  Company  without  further  action by the
shareholders.  The Company has no present plans to issue any shares of Preferred
Stock or Cumulative Convertible Preferred Stock.

Certain Anti-Takeover Provisions

      Under the Company's Certificate of Incorporation,  there are approximately
4,463,887  unreserved shares of Common Stock,  950,413 shares of Preferred Stock
and 22,407 shares of Cumulative Convertible Preferred Stock available for future
issuance  without  shareholder  approval,  as of June 7, 1996.  The existence of
authorized  but unissued  capital  stock,  together  with the  continued  voting
control of the Company by Allen (see "Risk Factors  -Voting Control by Principal
Shareholder"),  could have the effect,  either alone or in combination with each
other,  of making more difficult or  discouraging  an acquisition of the Company
deemed undesirable by its Board of Directors.

      Under the Company's Stock Option Plans,  as amended (the "Plans"),  in the
event of a change in control,  stock  appreciation  rights ("SAR's") and limited
SARs  outstanding  for at least six months and any stock  options  which are not
then  exercisable will become fully  exercisable and vested.  The Plans may have
the effect of  significantly  increasing the costs of acquiring the Company in a
hostile takeover.


                                   - 17 -










      The Company is subject to Section 203 of the Delaware General  Corporation
Law, which prohibits a Delaware corporation,  such as the Company, from engaging
in a wide range of  specified  transactions  with any  person who  becomes a 15%
stockholder,  under certain circumstances,  within three years after such person
became an "interested shareholder." Because Allen & Company Incorporated's stock
ownership  in  the  Company,  which  otherwise  would  cause  it to be  such  an
"interested  stockholder,"  antedates  the 1987  effective  date of Section 203,
Allen is not subject to the prohibitions of such Section.

Transfer Agent

      The  transfer  agent and  registrar  for  the  Common  Stock  is  American
Securities Transfer, Inc. of Denver, Colorado.

Item 15.    Indemnification of Directors and Officers.

      Section  145 of the  General  Corporation  Law of the  State  of  Delaware
empowers  the Company to, and the By-laws of the Company  provide that it shall,
indemnify  any person who was or is a party or is  threatened to be made a party
to any threatened,  pending or completed action, suit or proceeding by reason of
the  fact  that he is or was a  director,  officer,  employee  or  agent  of the
Company,  or is or was  serving  at the  request of the  Company as a  director,
officer, employee or agent of another corporation,  partnership,  joint venture,
trust or other enterprise,  against expenses,  judgments, fines and amounts paid
in settlement  actually and reasonably  incurred by him in connection  with such
action,  suit or  proceeding  if he  acted  in good  faith  and in a  manner  he
reasonably  believed  to be in, or not  opposed  to, the best  interests  of the
Company,  and,  with  respect  to any  criminal  action  or  proceeding,  had no
reasonable  cause to believe his conduct was unlawful;  except that, in the case
of an action or suit by or in the right of the Company,  no indemnification  may
be made in respect of any claim,  issue or matter as to which such person  shall
have been adjudged to be liable for negligence or misconduct in the  performance
of his duty to the  Company  unless  and only to the  extent  that the  Court of
Chancery or the court in which such action or suit was brought  shall  determine
that such  person is fairly and  reasonably  entitled  to  indemnity  for proper
expenses.

      The Company's  By-laws  provide,  pursuant  to Section  145 of the General
Corporation  Law of the State of  Delaware,  for  indemnification  of  officers,
directors,  employees  and  agents of the  Company  and  persons  serving at the
request of the Company in such  capacities  within other business  organizations
against certain losses,  costs,  liabilities and expenses  incurred by reason of
their position with the Company or such other business organizations.

Item 17.    Undertakings.

    (a)     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:

                  (i)  To include any prospectus required by Section 10(a)(3) of
the Securities Act of 1933;

                  (ii) To reflect in the  prospectus any facts or events arising
after the  effective  date of the  registration  statement  (or the most  recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental  change in the information set forth in the registration
statement;

                (iii) 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.

      Provided,  however,  that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
if the  registration  statement  is on Form S-3 or Form S-8 and the  information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic reports filed by the registrant  pursuant to Section 13 or
Section 15(d) of the Securities  Exchange Act of 1934 that are  incorporated  by
reference 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 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 which remain unsold at the termination of the
offering.


                                 - II- 2 -









      (b) 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 Section 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 herein,  and the offering of such securities
at the time shall be deemed to be the initial bona fide offering thereof.

      (c)  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,
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  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 will be
governed by the final adjudication of such issue.
