                        2,743,686 Shares of Common Stock

         The  shareholders  of Xiox listed  below are offering and selling up to
2,743,686 shares of common stock under this prospectus.  We will not receive any
part of the proceeds from this offering.

         We issued the  securities  covered by this  prospectus  to the  selling
shareholders  in connection  with either stock  purchase  agreements or warrants
between us and the selling  shareholders.  The selling shareholders will receive
certain shares covered by this prospectus upon the conversion of preferred stock
and the exercise of warrants. The precise number of shares of common stock which
the selling  shareholders will receive upon conversion of preferred stock cannot
be determined at this time. Accordingly,  the actual number of shares issued may
be higher or lower than the number specified above.

         The selling  shareholders  may offer  their  shares  through  public or
private transactions, on or off the Nasdaq SmallCap Market, at prevailing market
prices or privately  negotiated  prices. No period of time has been fixed within
which the shares may be offered or sold.

         We have agreed to bear the expense of the  registration and sale of the
shares  being   offered  by  the  selling   shareholders   (other  than  selling
commissions,  and the fees and  expenses  of counsel  and other  advisers to the
selling  shareholders).  We have agreed to  indemnify  the selling  shareholders
against certain liabilities,  including  liabilities under the Securities Act of
1933, as amended.

         Our common stock is quoted on the Nasdaq  SmallCap Market and is traded
under the symbol  "XIOX." On December 1, 1998,  the average of the high  and low
sale prices of one share of our stock on the Nasdaq Small Cap Market was $8.03.

                                  RISK FACTORS

         BEFORE  YOU  INVEST  IN OUR  COMMON  STOCK,  YOU  SHOULD  BE  AWARE  AN
INVESTMENT  IN OUR COMMON STOCK  INVOLVES A HIGH DEGREE OF RISK,  AND THAT THERE
ARE  VARIOUS  RISKS,  INCLUDING  THOSE  DESCRIBED  BELOW.  YOU  SHOULD  CONSIDER
CAREFULLY  THESE  RISK  FACTORS,  AND THE  OTHER  INFORMATION  INCLUDED  IN THIS
PROSPECTUS BEFORE YOU DECIDE TO PURCHASE SHARES OF OUR COMMON STOCK.

         SOME OF THE  INFORMATION  IN THIS DOCUMENT MAY CONTAIN  FORWARD-LOOKING
STATEMENTS.   YOU  CAN   IDENTIFY   SUCH   STATEMENTS   BY  NOTING  THE  USE  OF
FORWARD-LOOKING  TERMS SUCH AS "BELIEVES,"  "EXPECTS," "PLANS,"  "ESTIMATES" AND
OTHER SIMILAR  WORDS.  CERTAIN  RISKS,  UNCERTAINTIES  OR  ASSUMPTIONS  THAT ARE
DIFFICULT TO PREDICT MAY AFFECT SUCH STATEMENTS.  THE FOLLOWING RISK FACTORS AND
OTHER CAUTIONARY  STATEMENTS COULD CAUSE OUR ACTUAL OPERATING  RESULTS TO DIFFER
MATERIALLY FROM THOSE EXPRESSED IN ANY FORWARD-LOOKING STATEMENT. WE CAUTION YOU
TO KEEP IN MIND THE FOLLOWING RISK FACTORS AND OTHER  CAUTIONARY  STATEMENTS AND
TO REFRAIN FROM PLACING UNDUE RELIANCE ON ANY FORWARD-LOOKING STATEMENTS,  WHICH
SPEAK ONLY AS OF THE DATE OF THIS DOCUMENT.


Fluctuations in Quarterly Operating Results; Stock Price Volatility

         We  typically  experience  weaker  sales in the first  quarter  of each
calendar  year  compared  to sales for the last  quarter of the  previous  year.
Shortfalls in our revenues or earnings from levels  expected in the market could
have an immediate  and  significant  adverse  effect on the trading price of our
common stock.  Moreover,  our stock price is subject to the volatility generally
associated  with  technology  stocks and may also be affected by broader  market
trends unrelated to our performance.


Competition

         The  market  for  our   software   products  is   competitive   and  is
characterized by change in technology and user needs and the introduction of new
products.  In order to  remain  competitive,  we must  rapidly  respond  to such
changes,  including the enhancement  and upgrading of existing  products and the
introduction  of new  products.  Most  of our  competitors  and  many  potential
competitors  have  substantially  greater  financial,  marketing and  technology
resources than we do. Our major  competitors are Telco  Research,  ISI-Infortext
and  Nortel  (MAT).  We  cannot  be  certain  that we  will  be able to  compete
successfully against either current or potential competitors or that competition
will not have a material adverse effect on our business, consolidated results of
operations and financial condition.


Revenue Concentration

         Although no single customer accounted for more than 10% of our revenues
in 1996,  one customer  accounted  for 12% of revenue  during 1997.  We derive a
substantial portion of our revenues from sales of new call accounting  products,
updates and rate table renewals.  As such, any factor adversely  affecting sales
of new call accounting products, updates and rate table renewals, including such
factors as market acceptance,  product performance and reliability,  reputation,
price competition and competing products, as well as general economic and market
conditions,  could have a material adverse effect on our business,  consolidated
results of operations and financial condition.

Product Development and Introduction

         The software  products we offer are  internally  complex  and,  despite
extensive  testing and quality control,  may contain errors or defects ("bugs"),
especially when first  introduced.  Defects or errors could result in corrective
releases to our software products,  damage to our reputation,  loss of revenues,
an increase in product returns, claims for damages, or lack of market acceptance
of our  products,  any of which could have a material and adverse  effect on our
business, consolidated results of operations and financial condition.

         The software industry is characterized by rapid technological change as
well as changes in customer  requirements and  preferences.  We believe that our
future  results  will depend  largely  upon our ability to offer  products  that
compete  favorably  with respect to price,  reliability,  performance,  range of
useful  features,  continuing  product  enhancements,  reputation  and training.
Delays or difficulties,  including the discovery of product defects,  may result
in the delay or  cancellation of planned  development  projects and could have a
material and adverse effect on our business,  consolidated results of operations
and financial condition.  In addition,  increased  competition in the market for
call  accounting  products  could also have a negative  impact on our  business,
consolidated results of operations and financial condition.

         In 1997,  we began a  significant  development  effort in a new product
line addressing the combined telephony and data markets. Although we received in
1997 and 1998  approximately  $12.5  million  in  funding  for this  development
effort, we will require additional funding before the new product line returns a
profit.   The  additional   funding  will  be  used  for  marketing,   continued
engineering,  sales,  working  capital,  and to fund  research  and  development
activities.  We cannot be certain that we will be able to obtain the  additional
required funding, or that the new product line will become profitable. Moreover,
the introduction of the new product line may result in new competition.  Even if
the new product line is successfully introduced and is profitable,  we cannot be
certain that the new product line will result in profitability for Xiox.


Dependence on Distribution Channels

         We sell our  products  primarily  through  our  network  of  authorized
dealers. Our ability to effectively distribute our products depends in part upon
the financial and business condition of our distribution network. The loss of or
a significant reduction in business with any one of our major dealers could have
a material  adverse effect on our business,  consolidated  results of operations
and financial condition in future periods.

Year 2000 Readiness

         Definition.  The Year 2000  issue is the  result of  computer  programs
being written using two digits rather than four to define the  applicable  year.
Computer  programs and embedded  systems that have  time-sensitive  software may
recognize a date using "00" as the year 1900  rather than the year 2000.  If one
of our internal systems,  or those of a customer,  supplier or service provider,
do not correctly recognize date information when the year changes to 2000, there
could be an adverse impact on our operations.

         We have  assessed the  capability of our products sold to customers and
believe that for these products we have no exposure to contingencies  related to
the Year 2000 issue that would have a material  adverse  effect on our financial
position or results of  operations.  A list of Year 2000 Ready products has been
posted  on our web site and has been  sent to  customers  and  distributors  via
company newsletters.

                                        5

         Products.  Our products  receive data from other equipment such as PC's
and PBX's and can only properly handle Year 2000 dates if they receive Year 2000
compliant   data.  Some  systems  we  sell  or  have  sold  with  computer  BIOS
manufactured  prior to 1996 will need to have the  internal  clock  reset or the
BIOS modified in order to ensure proper performance.

         We believe  that the  likelihood  of a material  adverse  impact due to
problems  with products sold to customers is low and expect that any costs to be
incurred  to assure  Year 2000  capability  relating  to product  released or in
development will not have a material  adverse effect on our financial  position,
results of operations or cash flow.

         Internal Systems.  During the nine months ending September 30, 1998, we
continued   our  efforts  to  assess  and   remediate   our  computer   systems,
telecommunications  systems,  software  systems and related  equipment to ensure
each system will function  properly as the Year 2000  approaches.  The Year 2000
program is being conducted in four phases: (a)  Identification,  (b) Assessment,
(c) Remediation, and (d) Testing.

o        The  Identification  Phase  is  nearing  completion  for all  currently
         installed systems. The target for completion of this phase is 12/31/98.
         All new systems  acquired after this date will be subject to assessment
         prior to purchase.

o        The  Assessment  Phase is estimated at 75% complete and is targeted for
         completion by 12/31/98 for all systems currently implemented.

o        The Remediation Phase is estimated at 50% complete based on the systems
         requiring patches or upgrades.  The primary system requiring  attention
         is our  Manufacturing  and Financial  Management  System,  Macola.  The
         upgrade to this system is scheduled for completion in the first quarter
         of 1999.

o        The Testing  Phase is  currently  in a  preliminary  stage.  Testing of
         systems  and  interfaces  will  occur  near the end of the  Remediation
         Phase.

         We  currently  believe  our  information  systems  will  be  Year  2000
compliant by the end of the second quarter of 1999.

         External  Suppliers.  We have begun the process of identifying  our top
suppliers and seeking confirmation on their Year 2000 compliance. For those with
sizeable volume or that are single source for components or services, we will be
sending these suppliers a Year 2000 compliance survey. We expect this process to
be completed by mid-1999.

         We have received  information that the most critical systems,  services
or  products  supplied  to us by  external  sources  are Year 2000  ready or are
expected to be Year 2000 ready by mid 1999.

         We will be  developing  contingency  plans  for  systems  and  services
provided  by  vendors  that do not  respond  to our  requests  or fail in  their
readiness efforts.

         State of Readiness.  As of this date, we have made significant progress
in the process of identifying systems, completing an assessment and implementing
solutions for the high priority  internal  systems so that our computer  systems
will function properly with respect to dates in the year 2000 and thereafter.

         We are actively  participating  with  customers and suppliers to ensure
progress  is  being  made  and  that  the  dates  forecast  are  reasonable  and
attainable.

                                        6

         Costs. Other than time spent by our internal information technology and
other  personnel,  we have not incurred any  significant  costs in  identifying,
assessing and remediating year 2000 issues.

         Because we are in a growth phase,  systems improvement  initiatives are
underway to improve our  primary  business  systems.  We do not  anticipate  any
significant  costs  related  to  remediation  efforts  because  planned  systems
improvements shall include year 2000 readiness as a standard requirement.

         This  statement  assumes  that third party  suppliers  have  accurately
assessed  the  compliance  of their  products  and that they  will  successfully
correct  any issues in  non-compliant  products.  Because of the  complexity  of
correcting the Year 2000 issue, actual costs may vary from estimates.

         Although the total cost to obtain Year 2000  compliance is not known at
this time,  we currently  expect the cost to be less than  $150,000.  The actual
cost, however, could exceed this estimate.  These costs are not expected to have
a material  effect on our  financial  position,  results of  operations  or cash
flows.

         Contingency  Plans. Based upon the progress of our plan, we expect that
we will not  experience a material  disruption of our  operations as a result of
the change to the new millennium.  However,  we cannot be certain that the third
parties who have supplied  technology used in our mission  critical systems will
be successful in taking corrective action in a timely manner.

         We are  developing  contingency  plans  with  respect  to  certain  key
technology used in our mission critical systems, which are intended to enable us
to continue to operate.

         The contingency plans include  performing  certain processes  manually,
repairing  systems and changing  suppliers if  necessary,  although we cannot be
certain that these contingency plans will successfully  avoid service disruption
in the operation of business as usual.

Vermeulen,  who is one of our directors and is the managing director of FLV. Mr.
Vermeulen disclaims beneficial ownership of the shares held by FLV except to the
extent of his proportionate ownership interest in FLV.

         We sold 625,820  shares of Series A Preferred  Stock on  September  21,
1998,  and  1,282,169  shares of Series A Preferred  Stock on October 5, 1998 to
certain of the selling  shareholders in private  transactions.  On September 21,
1998 we granted warrants to purchase 50,000 shares of common stock to certain of
the  selling  shareholders  in  private  transactions.  The  shares  of Series A
Preferred  Stock are convertible  into an equivalent  number of shares of common
stock.  Such shares of common  stock,  issuable  upon either  conversion  of the
Series A Preferred Stock or exercise of the Warrants, are registered hereunder.

         In  addition,  we sold 40,000  shares of common stock to FLV on July 7,
1997,  and sold an additional  534,400 to FLV on September 24, 1997,  subject to
future adjustment.  On March 25, 1998, FLV acquired an additional 211,297 shares
of common  stock as a result  of a  purchase  price  adjustment  for the  shares
purchased on September  24,  1997.  These shares of common stock are  registered
hereunder.

         Each  selling  shareholder  has  represented  to us that he, she, or it
purchased  the  securities  described  above  for  investment,  with no  present
intention of distribution.  However,  in recognition of the fact that investors,
even though purchasing the securities  described above for investment,  may wish
to be legally permitted to sell their securities when they deem appropriate,  we
have  filed  with the  Commission  under  the  Securities  Act the  Registration
Statement  with respect to the sale of the common stock covered hereby from time
to time in through public or private transactions, on or off the Nasdaq SmallCap
Market, at prevailing market prices or privately negotiated prices,  through the
writing of options  on the  securities  owned by the  selling  shareholders,  or
through a combination of the foregoing.  We have agreed to prepare and file such
amendments and supplements to the Registration  Statement as may be necessary to
keep the Registration Statement effective until October 5, 2002.


                              PLAN OF DISTRIBUTION

         Any or all of the shares may be sold from time to time by each  selling
shareholder,    its   pledgees,    donees,    transferees,    distributees    or
successors-in-interest.  Each selling  shareholder  may sell all or a portion of
the shares  from time to time  while the  registration  statement  of which this
prospectus is a part remains effective.  The Company has agreed that it will use
its best efforts to keep the registration  statement  effective until October 5,
2002 (or a shorter  period if all the shares have been sold or disposed of prior
to such time). The aggregate proceeds to a selling  shareholder from the sale of
shares  offered by it hereby  will be the prices at which such  shares are sold,
less any commissions.

         Each selling shareholder may sell shares on the Nasdaq Smallcap Market,
in privately negotiated  transactions or otherwise,  at fixed prices that may be
changed,  at market prices prevailing at time of sale, at prices related to such
market prices or at negotiated prices.  Shares may be sold by one or more of the
following methods,  without limitation:  (a) block trades in which the broker or
dealer so engaged  will attempt to sell the shares as agent but may position and
resell a portion of the block as principal to facilitate  the  transaction,  (b)
purchases by a broker or dealer as principal and resale by such broker or dealer
for its account pursuant to this prospectus, (c) ordinary brokerage transactions
and  transactions  in  which  the  broker  solicits  purchasers,  (d)  privately
negotiated  transactions,  and (e) a combination of any such methods of sale. In
effecting  sales,  brokers and dealers  engaged by the selling  shareholder  may
arrange  for other  brokers or dealers to  participate.  Brokers or dealers  may
receive  commissions or discounts from the selling  shareholder (or, if any such
broker-dealer  acts  as  agent  for the  purchaser  of such  shares,  from  such
purchaser)  in amounts to be  negotiated  which are not expected to exceed those
customary in the types of transactions  involved.  Broker-dealers may agree with
the selling  shareholder  to sell a specified  number of shares at a  stipulated
price per share, and, to the extent such broker-dealer is unable to do so acting
as agent for the selling shareholder, to purchase as principal any unsold 

                                        9
<PAGE>

shares at the price  required to fulfill  the  broker-dealer  commitment  to the
selling  shareholder.   Broker-dealers  who  acquire  shares  as  principal  may
thereafter  resell  such  shares  from time to time in  transactions  (which may
involve  block  transactions  and  sales to and  through  other  broker-dealers,
including  transactions of the nature described  above) in the  over-the-counter
market or otherwise at prices and on terms then  prevailing at the time of sale,
at  prices  then  related  to the  then-current  market  price or in  negotiated
transactions  and, in connection  with such resales,  may pay to or receive from
the  purchasers  of such shares  commissions  as described  above.  Each selling
shareholder  may  also  sell  shares  in  accordance  with  Rule 144  under  the
Securities Act, rather than pursuant to this prospectus.

         In connection  with  distributions  of shares or  otherwise,  a selling
shareholder may enter into hedging  transactions  with  broker-dealers  or other
financial institutions. In connection with such transactions,  broker-dealers or
other financial  institutions  may engage in short sales of the Company's common
stock in the  course of hedging  the  positions  they  assume  with the  selling
shareholder.  The selling  shareholder may also sell the Company's  common stock
short  and  deliver  shares  to close  out such  short  positions.  The  selling
shareholder may also enter into option or other transactions with broker-dealers
or  other   financial   institutions   which   require  the   delivery  to  such
broker-dealers or other financial  institutions of shares offered hereby,  which
shares such  broker-dealers or other financial  institutions may resell pursuant
to this  prospectus.  The  selling  shareholder  may  also  pledge  shares  to a
broker-dealer  or  other  financial   institution,   and,  upon  default,   such
broker-dealer  or other  financial  institution  may effect sales of the pledged
shares pursuant to this prospectus.

         The selling  shareholder and any brokers and dealers through whom sales
of the shares are made may be deemed to be "underwriters"  within the meaning of
the Securities Act, and the commissions or discounts and other compensation paid
to such persons may be regarded as underwriters' compensation.  The Company will
pay all expenses of registration (including the fees and expenses of the selling
shareholder's  counsel)  incurred  in  connection  with this  offering,  but the
selling shareholder will pay all underwriting  discounts,  brokerage commissions
and other similar expenses incurred by the selling shareholder.  The Company has
agreed to indemnify the selling  shareholder  against  certain  losses,  claims,
damages and liabilities, including those arising under the Securities Act.

         The selling  shareholder may sell the shares at any price. Sales of the
shares at less than market  prices may depress the market price of the Company's
common stock. Moreover, generally, selling shareholders are not restricted as to
the number of shares which may be sold at any one time,  and it is possible that
a significant number of shares could be sold at the same time.

Item 15.  Indemnification of Directors and Officers

         Section  145  of  the  Delaware  General   Corporation  Law  permits  a
corporation to include in its charter  documents,  and in agreements between the
corporation  and its directors and officers,  provisions  expanding the scope of
indemnification beyond that specifically provided by the current law.

         Article VI of  the Registrant's  Certificate of Incorporation  provides
for the  indemnification  of directors to the fullest extent  permissible  under
Delaware law.

         Article VI of the Registrant's  Bylaws provides for the indemnification
of officers,  directors and third parties acting on behalf of the corporation if
such person acted in good faith and in a manner reasonably believed to be in and
not opposed to the best  interest of the  corporation,  and, with respect to any
criminal action or proceeding,  the  indemnified  party had no reason to believe
his or her conduct was unlawful.

         The Registrant  has entered into  indemnification  agreements  with its
directors and executive officers, in addition to indemnification provided for in
the Registrant's  Bylaws, and intends to enter into  indemnification  agreements
with any new directors and executive officers in the future.

Item 17.  Undertaking

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and persons controlling the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been informed that in the opinion of the Securities and Exchange  Commission
such indemnification is against public policy as expressed in the Securities 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 of controlling  persons 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 Securities  Act and will be governed by the final  adjudication
of such issue.

         2.  That,  for the  purpose  of  determining  any  liability  under the
Securities  Act of  1933,  each  such  amendment  shall  be  deemed  to be a new

any of the securities  being registered that remain unsold at the termination of
the offering.

         4. 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 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.

         5. To deliver or cause to be  delivered  with the  prospectus,  to each

     Re:  Xiox Corporation (the "Company") Registration Statement on Form S-3

Ladies and Gentlemen:

         We have  examined  the  Registration  Statement on Form S-3 to be filed
with the Securities and Exchange Commission (the "Registration  Statement"),  in
connection with the  registration  under the Securities Act of 1933, as amended,
of a shelf offering of (i) 2,693,686 shares of our common stock,  $.01 par value
per share (the "Shares") and (ii) up to 50,000 shares of our common stock,  $.01
par value per share,  issuable  upon  exercise  of certain  warrants to purchase
common stock of the Company (the "Warrant  Shares").  As your  counsel,  we have
examined the  proceedings  proposed to be taken in connection  with the sale and
issuance of the above-referenced securities.

         It is our opinion that the Shares are, and that the Warrant Shares when
issued upon exercise of the warrants  referred to in the Registration  Statement
will be, legally and validly issued, fully paid and nonassessable.

         We consent to the use of this opinion as an exhibit to the Registration
Statement,  and further consent to the use of our name wherever appearing in the
Registration  Statement,  including the Prospectus  constituting a part thereof,
and any amendment thereto.


                                   Very truly yours,

                         Consent of Independent Auditors



The Board of Directors
Xiox Corporation:

We consent to incorporation by reference in the Registration  Statement filed on
December 4, 1998, on Form S-3 of Xiox  Corporation  of our report dated February
13, 1998,  relating to the  consolidated  balance sheets of Xiox Corporation and
