                              PROSPECTUS SUMMARY

   The  following  summary is  qualified  in its  entirety by the more  detailed
information  and  consolidated  financial  statements,  including notes thereto,
appearing  elsewhere in, or incorporated  by reference  into,  this  Prospectus.
Unless otherwise indicated, the information contained in this Prospectus assumes
no exercise of the Underwriters' over- allotment option.

                                 THE COMPANY

   Inter-Tel  is a single point of contact,  full  service  provider of business
telephone systems,  telecommunications software applications, computer telephony
integration (CTI), voice processing software and long distance calling services,
as well as  maintenance,  leasing and support  services.  Because of the modular
design and high level of software content in the Company's  products,  including
its AXXESS and Inter-Tel Axxent systems, customers can readily increase the size
and  functionality  of their  systems as their future  telecommunications  needs
change.  The Company  believes that it is a leading  supplier of small to medium
size business telephone systems.

   The Company has developed a distribution  network of direct sales offices and
dealers which sells the Company's products to small to medium size organizations
and to divisions or departments of larger  organizations,  including Fortune 500
companies,  large service organizations and governmental agencies. In the United
States,  the  Company  has 25 direct  sales  offices  and a growing  network  of
hundreds of dealers who purchase directly from the Company.  The Company is also
in the process of expanding its international dealer network.

                                 RISK FACTORS

   In evaluating the Company's business,  prospective investors should carefully
consider the following factors in addition to the other information presented in
this Prospectus and the documents incorporated by reference herein.

RAPID TECHNOLOGICAL CHANGE AND DEPENDENCE ON NEW AND TIMELY PRODUCT
INTRODUCTIONS

   The market for the Company's systems,  products and services is characterized
by rapid technological  change and continuing demand for new products,  features
and  applications.  Current  competitors or new market  entrants may develop new
products  or product  features  that  could  adversely  affect  the  competitive
position of the Company's products.  Accordingly, the timely introduction of new
products and product features, as well as new  telecommunications  applications,
will be a key factor in the Company's future success. Occasionally, new products
contain  undetected  errors or "bugs" when  released.  Such bugs may result from
bugs contained in software products offered by the Company's  suppliers or other
third  parties that are intended to be compatible  with the Company's  products,
over which the Company has little or no control.  Although the Company  seeks to
minimize  the number of bugs in its products by its test  procedures  and strict
quality  control,  there can be no assurance that its new products will be error
free when introduced.  Any significant  delay in the commercial  introduction of
the Company's products due to bugs, any design modifications required to correct
bugs or any impairment of customer satisfaction as a result of bugs could have a
material  adverse  effect on the Company's  business and operating  results.  In
addition,  new products  often take several  months  before their  manufacturing
costs stabilize,  which may adversely  affect operating  results for a period of
time following  introduction.  The Company recently  announced its new Inter-Tel
Axxent telephone system, an OS/2 version of its voice processing software, and a
number of upgrades to its existing AXXESS systems. In the event that the Company
were to fail to  successfully  introduce  new  systems,  products or services or
upgrades to its  existing  systems or  products  on a regular and timely  basis,
demand for the Company's existing systems,  products and services could decline,
which  could  have a  material  adverse  effect on the  Company's  business  and
operating  results.  There can be no assurance  that the Company will be able to
successfully  develop  new  systems,   products,   services,   technologies  and
applications  on a timely basis as required by changing market needs or that new
systems or products or enhancements  thereto,  including its recently  announced
products and  upgrades,  when  introduced  by the Company  will  achieve  market
acceptance. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."

   The Company has recently developed and continues to develop products designed
to  address  the  emerging   market  for  the  convergence  of  voice  and  data
applications,  or computer  telephony  integration.  If the CTI market  fails to
develop or grows more slowly than the Company anticipates,  or if the Company is
unable for any reason to  capitalize on this emerging  market  opportunity,  the
Company's business and operating results could be materially adversely affected.

DEPENDENCE UPON CONTRACT MANUFACTURERS AND COMPONENT SUPPLIERS

   Certain  components  used  in  the  Company's   systems,   including  certain
microprocessors,  integrated  circuits,  power  supplies  and  voice  processing
interface cards, are currently available from a single source or limited sources
of supply, and certain of these components,  including integrated circuits,  are
currently in limited supply. In addition, the Company currently manufactures its
products  through a limited  number of  contract  manufacturers  located  in the
United  States,  the  Philippines  and the People's  Republic of China.  Foreign
manufacturing  facilities  are  subject  to changes  in  governmental  policies,
imposition  of tariffs  and import  restrictions  and other  factors  beyond the
Company's control.  Varian Associates,  Inc. ("Varian") currently manufactures a
significant  portion  of the  Company's  products  at  Varian's  Tempe,  Arizona
facility,  including substantially all of the printed circuit boards used in the
AXXESS  and  Inter-Tel  Axxent  systems.  From  time to time,  the  Company  has
experienced  delays in the supply of components and finished goods and there can
be no assurance that the Company will not experience  such delays in the future.
The  Company's  reliance  on third  party  manufacturers  involves  a number  of
additional  risks,  including reduced control over delivery  schedules,  quality
assurance  and costs.  Any delay in delivery or shortage of supply of components
or finished goods from Varian or any other supplier, or the Company's

                                        4


<PAGE>
inability to develop in a timely manner alternative or additional sources if and
when  required,  could  damage the  Company's  relationships  with  current  and
prospective  customers and could  materially and adversely  affect the Company's
business and operating results. The Company has no long term agreements with its
suppliers  that require the suppliers to provide fixed  quantities of components
or finished goods at set prices. There can be no assurance that the Company will
be able to  continue  to  obtain  components  or  finished  goods in  sufficient
quantities or quality or on favorable  pricing and delivery terms in the future.
See "Management's  Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Manufacturing."

COMPETITION

   The market for the Company's  telephone system products is highly competitive
and in recent periods has been  characterized by pricing  pressures and business
consolidations.  The  Company's  competitors  include  AT&T Corp.  ("AT&T")  and
Northern Telecom Limited ("NorTel"), as well as Comdial Corporation ("Comdial"),
EXECUTONE Information Systems, Inc. ("Executone"),  Mitel Corporation ("Mitel"),
Panasonic,  Siemens ROLM Communications  Inc. ("ROLM"),  Toshiba and others. The
Company also competes  against the regional Bell  operating  companies  (RBOCs),
which offer systems  produced by one or more of the  aforementioned  competitors
and also  offer  Centrex  systems  in which  automatic  calling  facilities  are
provided through  equipment  located in the telephone  company's central office.
Competition by the RBOCs could increase  significantly  if the RBOCs are granted
the right to manufacture  telephone  systems and equipment  themselves and/or to
bundle the sale of equipment with telephone calling  services,  activities which
to  date  they  have  been  restricted  from  undertaking.   Recent  legislative
initiatives would have the effect of increasing competition from the RBOCs.

   In the market for voice  processing  applications,  including voice mail, the
Company competes against  Centigram  Communications  Corporation  ("Centigram"),
Octel Communications  Corporation  ("Octel"),  Active Voice Corporation ("Active
Voice"), Applied Voice Technology, Inc. ("AVT") and other competitors, including
telephone  systems  manufacturers  such as AT&T,  NorTel and ROLM,  which  offer
integrated  voice  processing  systems  under their own label as well as through
various  OEM  arrangements.  Certain of the  Company's  competitors  may achieve
marketing  advantages by bundling their voice processing equipment with sales of
telephone  systems,  or by designing their telephone systems so that they do not
readily integrate with independent voice processing  systems.  Inter-Tel expects
that the  development  of industry  standards and the acceptance of open systems
architectures in the voice processing  market will reduce technical  barriers to
market entry and lead to increased competition.

   In the market for long distance services,  the Company competes against AT&T,
MCI  Telecommunications  Corporation ("MCI"),  Sprint Corporation ("Sprint") and
other  suppliers,  certain of which also  supply the long  distance  calling and
network  services  that the Company  resells.  Although  the Company  acquires a
variety of long  distance  calling  services in bulk from certain long  distance
carriers,  there can be no  assurance  that the Company will be able to purchase
long  distance  calling  services  on  favorable  terms from one or more of such
providers in the future. In addition,  a substantial majority of prospective new
long distance customers for the Company currently purchase long distance calling
services from the Company's competitors.  The Company believes that it is likely
to face increased  competition in the long distance  calling  services market to
the extent that  telecommunications  deregulation  enables  RBOCs to supply long
distance calling and network services or enables RBOCs and others to bundle long
distance,  local telephone and wireless services.  Moreover, the Company expects
to face increased  competition  in the future because low technical  barriers to
entry will allow new market entrants.

   Many of the Company's  competitors have  significantly  greater financial and
technical   resources,   name   recognition   and  marketing  and   distribution
capabilities  than the  Company.  The  Company  expects  that  competition  will
continue to be intense in the markets  addressed by its  products and  services,
and  there  can be no  assurance  that  the  Company  will be  able  to  compete
successfully in the future. See "Business--Competition."

PRODUCT PROTECTION AND INFRINGEMENT

   The  Company's  future  success  is  dependent  in part upon its  proprietary
technology.  The Company has no patents and relies  principally on copyright and
trade secret law and contractual provisions to

                                        5


<PAGE>
protect its intellectual property.  There can be no assurance that any copyright
owned by the Company will not be invalidated, circumvented or challenged or that
the  rights  granted  thereunder  will  provide  competitive  advantages  to the
Company.  Further,  there  can be no  assurance  that  others  will not  develop
technologies  that are similar or superior to the  Company's  technology or that
duplicate the Company's  technology.  As the Company  expands its  international
operations,  effective  intellectual  property  protection may be unavailable or
limited in certain foreign  countries.  There can be no assurance that the steps
taken by the Company will prevent misappropriation of its technology. Litigation
may be necessary in the future to enforce the  Company's  intellectual  property
rights,  to protect the Company's  trade secrets,  to determine the validity and
scope of the  proprietary  rights  of  others,  or to defend  against  claims of
infringement or invalidity.  Such litigation  could result in substantial  costs
and  diversion  of  resources  and could have a material  adverse  effect on the
Company's business and operating results.

   From  time  to  time,  the  Company  is  subject  to   proceedings   alleging
infringement  by the Company of intellectual  property rights of others.  If any
such claim is  asserted  against the  Company,  the Company may seek to obtain a
license under the third party's  intellectual  property rights.  There can be no
assurance that a license will be available on terms acceptable to the Company or
at all. In the alternative,  the Company could resort to litigation to challenge
any such claim, and the Company is currently engaged in one such proceeding. See
"Business--Legal  Proceedings." Any such litigation could require the Company to
expend  significant  sums and  could  require  the  Company  to pay  significant
damages,   develop  non-  infringing  technology  or  acquire  licenses  to  the
technology which is the subject of the asserted infringement, any of which could
have a material adverse effect on the Company's  business and operating results.
In the  event  that the  Company  is  unable  or  chooses  not to  license  such
technology or decides not to challenge  such third party's  rights,  the Company
could  encounter  substantial and costly delays in product  introductions  while
attempting  to design  around  such third party  rights,  or could find that the
development,  manufacture  or sale of products  requiring such licenses could be
foreclosed.

POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS; LIMITED BACKLOG

   The Company's  quarterly  operating results depend upon a variety of factors,
including the volume and timing of orders received  during the quarter,  the mix
of products sold and mix of distribution channels,  general economic conditions,
patterns  of  capital   spending  by  customers,   the  timing  of  new  product
announcements and releases by the Company and its competitors, pricing pressures
and the  availability  and cost of products and  components  from the  Company's
suppliers.  The Company's customers typically require the immediate shipment and
installation of systems. As a result, the Company has historically operated with
a relatively small backlog,  and sales and operating  results in any quarter are
principally  dependent on orders booked and shipped in that  quarter.  Moreover,
market demand for investment in capital  equipment such as telephone systems and
applications is largely dependent on general economic  conditions,  and can vary
significantly as a result of changing  conditions in the economy as a whole. The
Company's  expense levels are based in part on  expectations  as to future sales
and,  if sales  levels  do not meet  expectations,  operating  results  could be
adversely  affected.  Because  sales of systems  through the  Company's  dealers
produce  lower gross  margins  than sales  through the  Company's  direct  sales
organization,  operating  results will vary based upon the mix of sales  through
direct and  indirect  channels.  Although  the  Company to date has been able to
resell the rental streams from leases under its Totalease program profitably and
on a substantially  current basis, the timing and profitability of lease resales
from  quarter to quarter  could impact  operating  results,  particularly  in an
environment of fluctuating  interest rates.  Long distance sales have, in recent
periods,  grown at a faster rate than the  Company's  overall net sales and such
sales have lower gross margins than the Company's  core  business.  As a result,
gross  margins  could be  adversely  affected  in the event  that long  distance
calling services continue to increase as a percentage of net sales. In addition,
the Company is subject to seasonality in its operating results, as net sales for
the first and third quarters are frequently  less than those  experienced in the
fourth  and  second  quarters,  respectively.  As a result  of these  and  other
factors,  the  Company  has in the  past  and  could  in the  future  experience
fluctuations  in  sales  and  operating   results  on  a  quarterly  basis.  See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations."

MANAGEMENT OF GROWTH; IMPLEMENTATION OF NEW MANAGEMENT INFORMATION SYSTEMS

   The growth in the Company's  business has placed, and is expected to continue
to place, a significant strain on the Company's personnel,  management and other
resources.  The Company's  ability to manage any future growth  effectively will
require it to attract, train, motivate and manage new employees successfully, to
integrate new employees  into its overall  operations and to continue to improve
its operational, financial and management information systems. In particular, in
1995 the Company expects to begin  implementation of new management  information
systems  (MIS).  The Company  believes  the new MIS systems  will  significantly
affect many  aspects of its  business,  including  its  accounting,  operations,
purchasing, sales and marketing functions. The successful implementation of such
systems is expected to be crucial to the Company's  provision of services and to
enable future growth.  There can be no assurance that the Company will implement
its new MIS systems in an  efficient  and timely  manner or that the new systems
will be adequate  to support the  Company's  operations.  Following  the initial
implementation  of the new MIS  systems,  the  Company's  corporate  offices are
expected to be moved to another  location in Phoenix,  Arizona.  There can be no
assurance  that such move  will be  accomplished  in an  orderly  and  efficient
manner.

   The  Company  has made  strategic  acquisitions  in the past and  expects  to
continue to do so in the future.  Acquisitions  require a significant  amount of
the Company's management attention and financial and operational resources,  all
of which are limited.  The  integration of acquired  entities may also result in
unexpected  costs and disruptions,  and significant  fluctuations in, or reduced
predictability  of,  operating  results  from period to period.  There can be no
assurance   that  an  acquisition   will  not  adversely   affect  the  business
relationships  of the  Company or the  acquired  entity  with  their  respective
suppliers or customers. Further, there can be no assurance that the Company will
successfully  integrate  the acquired  operations or achieve any of the intended
benefits  of  an  acquisition.  The  Company's  failure  to  manage  its  growth
effectively  could have a material  adverse effect on its business and operating
results. See "Use of Proceeds."

RELIANCE ON DEALER NETWORK

   A substantial portion of the Company's net sales are made through its network
of  independent  dealers.  The  Company  faces  intense  competition  from other
telephone system and voice  processing  system  manufacturers  for such dealers'
attention,  as most of the Company's  dealers carry  products which compete with
the Company's products.  The Company has no long term agreements with any of its
dealers, and there can be no assurance that any such dealer will not promote the
products  of the  Company's  competitors  to  the  detriment  of  the  Company's
products.  The loss of any significant dealer or group of dealers,  or any event
or condition  adversely  affecting the Company's  dealer  network,  could have a
material  adverse  effect on the Company's  business and operating  results.  In
recent  years the Company has  effected a number of  strategic  acquisitions  of
resellers  of  telephony  products  and  integrated  these  operations  with its
existing  direct  sales  operations  in the same  geographic  areas and in other
strategic  markets.  There can be no assurance that one or more of the Company's
dealers  will  not be  acquired  by a  competitor  and that the loss of any such
dealer  so  acquired  will not  adversely  affect  the  Company's  business  and
operating  results.  See  "Management's  Discussion  and  Analysis of  Financial
Condition and Results of Operations" and "Business--Sales and Distribution."

RISKS OF PROVIDING LONG DISTANCE SERVICES

   Inter-Tel  depends on a reliable  supply of  telecommunications  services and
information  from  several  long  distance  carriers.  Because  it does  not own
transmission  facilities,  the Company relies on long distance  carriers for the
provision  of  network  services  to the  Company's  customers  and for  billing
information.  Long  distance  services  are subject to extensive  and  uncertain
governmental  regulation  on both the federal and state  level.  There can be no
assurance  that the  promulgation  of certain  regulations,  such as regulations
requiring the reduction of direct-dial  billing rates, will not adversely affect
the Company's business and operating results. The Company currently resells long
distance  services  pursuant to  contracts  with three of the six  largest  long
distance carriers with U.S. networks, and is negotiating a similar contract with
a  fourth.  These  contracts  typically  have a  multi-year  term in  which  the
Company's prices are relatively fixed and have minimum use  requirements.  There
can be no assurance that the Company will meet

                                        7


<PAGE>


minimum use commitments,  will be able to negotiate lower rates with carriers in
the  event of any  decrease  in end user  rates  or will be able to  extend  its
contracts with long distance  carriers at prices  favorable to the Company.  The
Company's  ability to continue to expand its long  distance  service  operations
will depend on its ability to continue to secure reliable long distance services
from a number of long distance  carriers and the willingness of such carriers to
continue to make  telecommunications  services and billing information available
to the Company on favorable terms. See "Business--Products and Services."

DEPENDENCE ON KEY PERSONNEL

   The  Company is  dependent  on the  continued  service of, and its ability to
attract  and  retain,  qualified  technical,  marketing,  sales  and  managerial
personnel. The competition for such personnel is intense, and the loss of any of
such  persons,  as well as the failure to recruit  additional  key technical and
sales personnel in a timely manner,  would have a material adverse effect on the
Company's  business and operating  results.  There can be no assurance  that the
Company will be able to continue to attract and retain the  qualified  personnel
necessary for the  development of its business.  The Company  currently does not
have employment contracts with any of its employees. See "Business--Employees."

POSSIBLE VOLATILITY OF STOCK PRICE

   The Company  believes  that factors  such as  announcements  of  developments
relating to the Company's  business,  fluctuations  in the  Company's  operating
results, general conditions in the telecommunications  industry or the worldwide
economy,  changes in legislation or regulation affecting the  telecommunications
industry,  an outbreak of  hostilities,  a shortfall in revenue or earnings from
securities analysts' expectations, announcements of technological innovations or
new products or enhancements by the Company or its competitors,  developments in
intellectual  property rights and  developments  in the Company's  relationships
with its customers and suppliers  could cause the price of the Company's  Common
Stock to  fluctuate,  perhaps  substantially.  In addition,  in recent years the
stock  market in  general,  and the market for  shares of  technology  stocks in
particular,  have experienced extreme price fluctuations,  which have often been
unrelated to the operating  performance of affected  companies.  There can be no
assurance  that  the  market  price  of the  Company's  Common  Stock  will  not
experience significant  fluctuations in the future,  including fluctuations that
are unrelated to the Company's performance. See "Price Range of Common Stock."

CONCENTRATION OF OWNERSHIP

   Immediately  following this offering,  the Company's Chairman of the Board of
Directors and Chief Executive Officer will beneficially own approximately 25% of
the  outstanding   shares  of  the  Common  Stock   (approximately  22%  if  the
Underwriters'  over-allotment option is exercised in full). As a result, he will
have the ability to exercise  significant  influence over all matters  requiring
shareholder approval. In addition, the concentration of ownership could have the
effect of  delaying  or  preventing  a change in  control  of the  Company.  See
"Selling Shareholders."

                                 THE COMPANY

   
   The Company was  incorporated in Arizona in July 1969. Its principal  offices
are  located  at 7300  West  Boston  Street,  Chandler,  Arizona  85226  and its
telephone number at that address is (602) 961-9000.  As used in this Prospectus,
"Inter-Tel"  or  the  "Company"  refers  to  Inter-Tel,   Incorporated  and  its
subsidiaries.

                               USE OF PROCEEDS

   
   The net  proceeds to the  Company  from the sale of the  2,000,000  shares of
Common Stock  offered by it hereby are estimated to be $30.8  million,  based on
the  public  offering  price of  $16.625  per share and after  deduction  of the
underwriting  discount and  estimated  offering  expenses.  A portion of the net
proceeds may be used to finance acquisitions of resellers of telephony products,
other strategic acquisitions or corporate alliances.  The Company considers such
acquisitions  on an  ongoing  basis,  but  has no  current  commitments  for any
acquisition  which  would have a  material  impact on the  Company's  results of
operations or financial condition. The Company intends to use the balance of the
net proceeds primarily for working capital, capital expenditures relating to the
upgrade of infrastructure and other general corporate  purposes.  In particular,
the  Company  expects  to use up to  $5.0  million  of the net  proceeds  of the
offering  for capital  expenditures  relating to the  implementation  of new MIS
systems.  Pending  such  uses,  the  Company  will  invest the net  proceeds  in
investment grade short term income producing  investments.  The Company will not
receive any proceeds from the sale of shares by the Selling Shareholders. 

    

                               DIVIDEND POLICY

   The  Company  has  paid no cash  dividends  on its  Common  Stock  since  its
incorporation  and anticipates that for the foreseeable  future it will continue
to retain any earnings for use in its business.  The Company's  credit agreement
limits the Company's ability to pay cash dividends on its Common Stock.

                     SELECTED CONSOLIDATED FINANCIAL DATA

   The following table summarizes certain selected  consolidated  financial data
of the Company and its subsidiaries. The selected consolidated financial data as
of and for each of the five years  ended  December  31,  1994 and the six months
ended June 30, 1994 and 1995 have been restated to include the financial results
of American Telcom Corp. of Georgia, Inc. and Access West, Inc., which were both
acquired in May 1995 in  transactions  accounted  for as poolings of  interests.
Such acquisitions did not constitute  "significant business combinations" within
the meaning of the rules of the Securities and Exchange Commission. The selected
consolidated  financial data, exclusive of the acquisitions,  as of December 31,
1993 and 1994, and for each of the years in the three-year period ended December
31, 1994,  are derived from  consolidated  financial  statements  that have been
audited by Ernst & Young LLP,  independent  auditors,  which are incorporated by
reference  into this  Prospectus.  The  selected  consolidated  financial  data,
exclusive of the  acquisitions,  as of December 31, 1990,  1991 and 1992 and for
each of the years in the  two-year  period  ended  December 31, 1991 are derived
from audited consolidated  financial statements not included in this Prospectus.
The  selected  consolidated  financial  data as of  June  30,  1995  and for the
six-month  periods  ended  June 30,  1994 and 1995 are  derived  from  unaudited
consolidated  financial statements which are incorporated by reference into this
Prospectus.   The  unaudited   consolidated  financial  statements  include  all
adjustments,   consisting  of  normal  recurring  accruals,  which  the  Company
considers  necessary for a fair  presentation of the financial  position and the
results of operations for these periods.  Operating results for six months ended
June 30, 1995 are not necessarily indicative of the results that may be expected
for the entire fiscal year ending December 31, 1995 or future periods.  The data
presented below should be read in conjunction  with the  Consolidated  Financial
Statements and Notes thereto and other  financial  information  incorporated  by

              MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                     CONDITION AND RESULTS OF OPERATIONS

GENERAL

   Inter-Tel  is a single point of contact,  full  service  provider of business
telephone systems,  telecommunications software applications, computer telephony
integration,  voice processing  software and long distance calling services,  as
well as maintenance, leasing and support services.

   The Company has developed a network of direct sales offices and dealers which
sells the Company's  products,  and in recent periods the Company has focused on
expanding its direct sales capabilities and its dealer network.  The Company has
effected a number of strategic  acquisitions of resellers of telephony  products
and integrated these operations with its existing direct sales operations in the
same geographic areas and in other strategic markets.

   Sales of systems through the Company's dealers typically generate lower gross
margins than sales through the  Company's  direct sales  organization,  although
direct  sales   typically   require  higher  levels  of  selling,   general  and
administrative  expenses.  In addition,  the Company's long distance and network
services  typically  generate lower gross margins than sales of system products.
Accordingly, the Company's margins may vary from period to period depending upon
distribution channel and product mix. In the event that sales through dealers or
sales of long  distance  services  increase as a  percentage  of net sales,  the
Company's overall gross margin would decline.

   The Company's  operating results depend upon a variety of factors,  including
the volume and timing of orders  received  during a period,  the mix of products
sold and mix of distribution channels, general economic conditions,  patterns of
capital  spending  by  customers,  the timing of new product  announcements  and
releases  by  the  Company  and  its  competitors,  pricing  pressures  and  the
availability  and cost of products and components from the Company's  suppliers.
In addition,  the Company is subject to seasonality in its operating results, as
net  sales  for the first and third  quarters  are  frequently  less than  those
experienced during the fourth and second quarters, respectively.

   All periods have been restated to reflect the acquisitions of American
Telcom Corp. of Georgia, Inc. and Access West, Inc. in May 1995. Each
transaction was accounted for as a pooling of interests.

RESULTS OF OPERATIONS

   The following  table sets forth certain  statement of operations  data of the
Company expressed as a percentage of net sales for the periods indicated:

 SIX MONTHS ENDED JUNE 30, 1995 COMPARED TO SIX MONTHS ENDED JUNE 30, 1994

   Net sales  increased  21.3% to $70.9  million in the first six months of 1995
from $58.5  million in the first six months of 1994.  The increase was primarily
attributable  to  increased  shipments of AXXESS  systems and software  products
through the Company's  dealer network and direct sales offices,  and an increase
in sales of long distance services.

   Gross profit increased to $29.1 million,  or 41.0% of net sales, in the first
six months of 1995 from $23.0 million,  or 39.3% of net sales,  in the first six
months of 1994.  The  increase  in gross  margin was  primarily  due to a higher
percentage of sales derived from AXXESS  systems and software,  which was offset
in part by a higher  percentage of sales through  dealers and increased sales of
the Company's long distance services.

   Research and development  expenses increased to $2.9 million,  or 4.0% of net
sales, in the first six months of 1995 from $2.1 million,  or 3.7% of net sales,
in the first six months of 1994.  This  increase was primarily  attributable  to
expenses  relating to the  introduction  of new  products,  including the AXXESS
version 3.0, the  Inter-Tel  Axxent and  AxxessoryTalk  version 3.0. The Company
expects that  research and  development  expenses  will  continue to increase in
absolute  dollars as the Company  continues to develop and enhance  existing and
new technologies and products. These expenses may vary, however, as a percentage
of net sales.

   Selling,  general and administrative  expenses increased to $20.3 million, or
28.7% of net sales, in the first six months of 1995 from $16.8 million, or 28.7%
of net sales, in the first six months of 1994. This increase in absolute dollars
was  primarily  attributable  to the costs  associated  with hiring and training
approximately 40 sales personnel throughout Inter-Tel's 25 direct sales offices.
Higher  sales  commissions  were also paid  based upon  increased  levels of net
sales.  The Company expects that selling,  general and  administrative  expenses
will increase in absolute dollars, but may vary as a percentage of net sales.

   Interest  and other income in both  periods  consisted  primarily of interest
income.

   Net income  increased 17.3% to $3.1 million,  or $.28 per share, in the first
six months of 1995 from $2.7 million, or $.24 per share, in the first six months
of 1994. Net income includes a special charge of approximately $815,000, or $.07
per share,  reflecting the costs  associated with  integrating the operations of
the two  acquired  companies.  The special  charge  principally  includes  costs
associated   with  redundancy  in  inventories,   equipment   abandonment,   the
combination and relocation of business operations,  employee  terminations,  and
the write-off of intangible  assets.  Without this special  charge,  the Company
would have  reported net income of $3.9 million,  or $.35 per share,  in the six
months ended June 30, 1995, an increase of 48.1% over net income of $2.7 million
in the first six months of 1994.

 YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993

   Net sales  increased  19.8% to $122.6  million in 1994 from $102.4 million in
1993. The increase in net sales was primarily attributable to increased sales of
telephone  systems  through the  Company's  direct sales  offices and its dealer
network.  The  remaining  increases  occurred in long  distance  sales and other
operations.  Shipments to the expanded dealer network more than offset decreased
shipments  to  Premier  Telecom  Products,  Inc.  ("Premier"),   previously  the
Company's  private  label  distributor.  Shipments  to  Premier  are  no  longer
significant.

   Gross profit increased to $49.1 million,  or 40.1% of net sales, in 1994 from
$39.6 million,  or 38.7% of net sales,  in 1993.  This increase in gross margins
reflected  the  transition  from  Premier and other  distributors  to the direct
dealer network and the expansion of AXXESS system and software sales.

   Research and development  expenses increased to $4.5 million,  or 3.7% of net
sales, in 1994 from $4.1 million,  or 4.0% of net sales, in 1993. These expenses
in both 1994 and 1993 were directed principally to the continued  development of
the AXXESS and  Inter-Tel  Axxent  software  and  systems  and voice  processing
software applications.

   Selling,  general and administrative  expenses increased to $35.8 million, or
29.2% of net sales in 1994, from $29.0 million,  or 28.5% of net sales, in 1993.
This reflected increased incentive and other compensation,  additional personnel
to support the direct dealer network and expenses  associated  with the start up
of the Company's Asian subsidiary.

                                       13



<PAGE>
   Interest and other income  increased in 1994  principally from the investment
for a full year of the funds  received  in a public  offering  of the  Company's
Common Stock in November 1993 and funds generated through operating cash flow.

   Net income  increased 52.7% to $5.9 million,  or $.55 per share, in 1994 from
$3.9 million,  or $.43 per share, in 1993. Net income per share in 1994 is based
on an additional 1.8 million average shares outstanding in 1994,  reflecting the
1993 public offering.

 YEAR ENDED DECEMBER 31, 1993 COMPARED TO YEAR ENDED DECEMBER 31, 1992

   Net sales  increased  17.4% in 1993 to $102.4  million from $87.2  million in
1992. The increase in net sales primarily  reflected increased sales through the
Company's  direct sales  offices,  including new customer sales and higher sales
through the  Company's  Totalease  program.  Sales to the  Company's  network of
direct  dealers  following the  transition in the  distribution  channel,  which
commenced in April 1993, offset a decline in sales to Premier.  Sales to Premier
decreased to $10.1 million, or 9.9% of net sales, in 1993 from $17.1 million, or
19.6% of net sales, in 1992.

   In 1993, gross profit increased to $39.6 million, or 38.7% of net sales, from
$33.6 million,  or 38.5% of net sales, in 1992.  Gross margins  improved in 1993
because of higher sales through the Company's direct sales channel and increased
sales through the Company's  Totalease program,  as well as higher gross margins
on sales to direct dealers following the transition away from Premier.

   Research and development expenses increased to $4.1 million in 1993 from $3.9
million  in 1992  and  were  4.0% and  4.5% of net  sales,  respectively.  These
expenses in both periods were directed  principally to continued  development of
the Company's new AXXESS system.

   Selling,  general and administrative  expenses increased to $29.0 million, or
28.5% of net sales, in 1993, from $24.5 million, or 28.1% of net sales, in 1992.
This increase reflected increased compensation,  additional personnel to support
the Company's direct dealer network and a one-time  expense  associated with the
Company's move into its new  headquarters.  Such increases were partially offset
by reductions in key executive incentive compensation.

   Interest and other  income in 1993  consisted  primarily of interest  income.
Interest  and other  income in 1992 was derived  principally  from a gain on the
sale of the Company's  headquarters,  as well as interest income relating to the
refund of import duties.  Interest  expense  during 1993  decreased  principally
because of lower interest rates and reduced long and short term borrowings.

   Net income in 1993  increased to $3.9 million,  or $.43 per share,  from $3.2
million, or $.37 per share, in 1992.

INFLATION/CURRENCY FLUCTUATION

   Inflation and currency fluctuations have not previously had a material impact
on Inter-Tel's  operations.  International sales and procurement agreements have
traditionally been denominated in U.S. currency.  Moreover, a significant amount
of  contract  manufacturing  has been or is  expected  to be  moved to  domestic
sources.  The expansion of  international  operations in the United  Kingdom and
Europe and  anticipated  increased  sales in Japan and Asia and elsewhere  could
result in higher  international  sales as a percentage  of total  revenues,  but
international revenues are currently not significant.

LIQUIDITY AND CAPITAL RESOURCES

   
   The Company continues to expand its dealer network, which has required and is
expected  to  continue  to  require  working  capital  for  increased   accounts
receivable  and  inventories.  During  the  first six  months of 1995,  accounts
receivable and inventories  increased  approximately $9.1 million. This increase
was  principally  funded by operating cash flow and existing cash balances.  The
Company also expended  approximately $4.0 million during the first six months of
1995 for  property  and  equipment.  The  Company  intends to  continue  to make
significant capital expenditures  through the end of 1995,  principally relating
to the  implementation  of the Company's new MIS systems.  At June 30, 1995, the
Company had $10.4 million in cash and  equivalents,  which represents a decrease
of approximately $5.0 million from December 31, 1994. 

    

                                       14


<PAGE>

   The Company has a loan agreement with Bank One, Arizona,  N.A. This agreement
provides for a $5.0 million, unsecured, revolving line of credit, which is being
used  primarily  to  support  international  letters  of  credit  to  suppliers.
Outstanding  balances  bear  interest at the bank's  prime  rate.  In the fourth
quarter of 1993,  the Company repaid all long and short term debt from a portion
of the net  proceeds  received  from its 1993  public  offering.  The  remaining
proceeds were added to working capital.

   
   The Company  offers to its  customers  lease  financing  and other  services,
including its Totalease program,  through its Inter-Tel Leasing subsidiary.  The
Company  funds its  Totalease  program  in part  through  the sale to  financial
institutions of rental income streams under the leases. Resold Totalease rentals
totaling  $27.0 million and $19.9 million  remain  unbilled at June 30, 1995 and
December 31, 1994,  respectively.  The Company is obligated to  repurchase  such
income  streams in the event of defaults by lease  customers  and,  accordingly,
maintains  reserves based upon loss  experience and past due accounts.  Although
the Company to date has been able to resell the rental streams from leases under
the Totalease  program  profitably and on a  substantially  current  basis,  the
timing and  profitability  of lease resales could impact the Company's  business
and operating  results,  particularly in an environment of fluctuating  interest
rates.  If the Company is required to  repurchase  rental  streams and  realizes
losses thereon in amounts exceeding its reserves,  its operating results will be
adversely affected.
    

   The Company believes that the net proceeds from this offering and its working
capital and credit  facilities,  together with cash generated  from  operations,
will be  sufficient  to fund  purchases of capital  equipment,  finance any cash
acquisitions which the Company may consider and provide adequate working capital
for the foreseeable  future.  However,  to the extent that additional  funds are
required in the future to address  working  capital needs and to provide funding
for capital expenditures,  expansion of the business or additional acquisitions,
the Company  will seek  additional  financing.  There can be no  assurance  that
additional financing will be available when required or on acceptable terms.

                                   BUSINESS

   Inter-Tel  is a single point of contact,  full  service  provider of business
telephone systems,  telecommunications software applications, computer telephony
integration (CTI), voice processing software and long distance calling services,
as well as  maintenance,  leasing and support  services.  Because of the modular
design and high level of software content in the Company's  products,  including
its AXXESS and Inter-Tel Axxent systems, customers can readily increase the size
and  functionality  of their  systems as their future  telecommunications  needs
change.  The Company  believes that it is a leading  supplier of small to medium
size business telephone systems.

   
   The Company has developed a distribution  network of direct sales offices and
dealers which sells the Company's products to small to medium size organizations
and to divisions or departments of larger  organizations,  including Fortune 500
companies,  large service organizations and governmental agencies. In the United
States,  the  Company  has 25 direct  sales  offices  and a growing  network  of
hundreds of dealers that purchase directly from the Company. The Company is also
in the process of expanding its international dealer network. 

    

INDUSTRY BACKGROUND

   In recent years, advances in telecommunications technologies have facilitated
the   development   of   increasingly   sophisticated   telephone   systems  and
applications.   Telecommunications  systems  have  evolved  from  simple  analog
telephones to sophisticated digital systems and applications. Users increasingly
rely  upon  a   variety   of   applications,   including   conference   calling,
speakerphones,   voice   processing   and   automated   attendant,   to  improve
communications  within  their  organizations  and with  customers  and  vendors.
Digital   technology   has   facilitated   the   integration  of  computing  and
telecommunications  technologies,  also known as computer telephony integration,
which  has made  possible  a number of new  applications  that  further  enhance
productivity. Examples of these applications include automatic call distribution
(which  provides  for  queuing  and  prioritization  of  incoming  calls),  call
accounting  (which  permits  accounting  for  telephone  usage and toll  calls),
facsimile storage and forwarding,  electronic data interchange between customers
and  vendors  and  the  use of  automatic  number  identification  coupled  with
"database look-up," where customer information is retrieved automatically from a
computerized database when the customer calls.

   Historically,  advanced  technologies  and  applications  have been initially
introduced in large  telecommunications  systems.  However, small to medium size
businesses and other  organizations,  as well as small to medium size facilities
of larger  organizations,  are  increasingly  requiring  advanced  features  and
applications  at a more effective  price-performance  point, in order to improve
efficiency and enhance competitiveness.

   Following  the breakup of the Bell  telephone  system in 1984,  which removed
restrictions  on the  ability of the RBOCs to  purchase  telephone  systems  and
equipment from independent suppliers and to resell such systems and equipment to
end users, the market for  telecommunications  systems and  applications  became
increasingly fragmented. The number of independent suppliers and distributors of
telecommunications  equipment  initially  increased,  but  increased  levels  of
competition led to consolidation among suppliers and distributors.  In addition,
different  telecommunications systems and applications were often available from
only one or a limited  number of suppliers,  which required  businesses  seeking
complete   telecommunications  systems  to  work  with  a  number  of  different
suppliers.  A business seeking a telephone system,  voice mail and long distance
services  would most  likely  purchase  the  products  and  services  from three
separate vendors.

   As businesses' telecommunications requirements have become more advanced, the
integration  of  the  different  parts  of  a  system  has  become  increasingly
difficult.   The  system  integration,   service  and  support  capabilities  of
telecommunications  suppliers have become significant  competitive  factors.  In
order to meet the needs of end users,  suppliers have been increasingly required
to develop close relationships with end users.

                                       16



<PAGE>
STRATEGY

   The  Company's  strategy  is to  offer  to its  customers,  through  a  broad
distribution network, a single source for their full range of telecommunications
requirements,  and to provide to its market segment, on a cost-effective  basis,
advanced  technologies and services that have achieved  acceptance in the market
for larger systems.

   o  Offer Total Telephony Solution

   The Company  offers a broad  range of products  and  services  that  provides
customers   with  a  single   source  to  fulfill   their   current  and  future
telecommunications and telephony needs. Inter-Tel couples this solution-oriented
approach  with a high level of  customer  service  and a  commitment  to quality
throughout  the  Company's  operations.  The  Company's  telephone  switches and
telephones can be integrated with the Company's long distance calling  services,
voice  mail,  automated  attendant  and other  telecommunications  applications,
support for interactive voice response and leasing and support services. Because
of the modular  design of the  Company's  systems and the high level of software
content  in  its  products,   customers  can  readily   increase  the  size  and
functionality  of their  systems as their  telephony  needs change by purchasing
additional equipment, applications or services or by upgrading to new systems or
advanced  versions of existing  systems.  The Company  believes that many of its
customers  prefer to purchase  telephony  equipment  and services  from a single
source because of the convenience,  consistency of service,  ease of upgrade and
confidence  in the  performance  of integrated  systems and services.  

   o Provide Advanced Products

   The Company seeks to provide its customers  with advanced  telecommunications
technologies on a cost-effective  basis. In many cases, the Company develops new
technologies  as  software  upgrades or add-ons to  existing  products.  Ongoing
research  and  development  efforts  are  directed  to  the  development  of new
products,  applications  and  services  for  sale  into the  Company's  existing
customer base and to new customers.  The Company's  AXXESS telephone system is a
fully-digital,  software-intensive  system  which  incorporates  digital  signal
processing (DSP) components and open architecture  interfaces.  These interfaces
enable the AXXESS telephone  system to interact with  applications and databases
on attached computers, and permit customers to integrate their telephone systems
with a number  of  computer-based  applications,  including  automatic  database
look-up,  call accounting,  automatic call  distribution,  facsimile storage and
forwarding and exchange of electronic  data between  customers and vendors.  The
Company  recently  announced the  introduction of the Inter-Tel Axxent telephone
system,   which  is  intended  to  bring  many  of  the  advanced  features  and
functionality of the AXXESS system to smaller  businesses.  The Inter-Tel Axxent
is  expected  to have a high level of computer  telephony  integration  and full
function plug-in voicemail. Through CTI and advanced network services, Inter-Tel
provides  technology  that is designed to enable its  customers to improve their
efficiency and enhance their competitiveness. 

   o Broaden Range of Services

   The Company seeks to expand the range of telephony  services it offers to end
users.  In addition to its telephone  systems and software,  Inter-Tel  offers a
variety of long distance calling services,  including domestic and international
calling services,  800 calling  services,  dedicated  services,  voice and video
conferencing  and customized  billing.  Inter-Tel's  strategy is to increase the
volume of its long distance  services,  which the Company expects will enable it
to become  increasingly  price  competitive.  The  Company's  Totalease  program
enables an end user to acquire a full range of telephony systems,  applications,
maintenance  and support  services,  as well as lease  financing,  from a single
source. In addition, the Company resells to end users a number of the industry's
leading  telecommunications  products,  including  voice and video  conferencing
equipment,  headsets,  paging equipment and wireless communications equipment. 

   o Expand Distribution Channels

   The Company  continues to expand its distribution  channels through a growing
network of dealers,  expansion of the Company's direct sales force and extension
into international markets. The Company has established sales relationships with
hundreds of dealers and continues to expand this network.  The Company  believes
that  expansion of this  network and the  Company's  direct  sales  offices will
facilitate the

                                       17



<PAGE>
expansion  of  the  Company's  overall  distribution  network  and  enhance  the
Company's  access to end user customers,  thereby enabling the Company to better
satisfy  customer  requirements.  The Company is in the process of  establishing
dealer  networks in Japan and Asia and is  expanding  its dealer  network in the
United Kingdom and Europe. The Company has expanded its direct sales activity in
recent periods through strategic acquisitions of resellers of telephony products
and  services in areas where the Company has existing  direct sales  offices and
other strategic markets, and considers additional  acquisition  opportunities on
an ongoing basis. The Company also intends to expand its  distribution  channels
by selling certain of its CTI products and services through  computer  equipment
dealers and software resellers.

PRODUCTS AND SERVICES

   The Company  has a broad  range of products  designed to support the needs of
businesses and other organizations requiring telephone system installations. The
Company's  principal products are telephone systems which support  installations
of 5 to 500 telephones, CTI, voice processing software and long distance calling
services.  The Company's principal system sales consist of systems supporting 11
to 200  telephones  with  suggested  retail  prices of up to $200,000 per system
depending on  configuration.  The Company also offers  maintenance,  leasing and
support services, and resells other telecommunications products.

 TELEPHONE SYSTEMS

   AXXESS.  The  Company's  AXXESS  version  2.0  supports  a total of 12 to 160
telephones  and trunk  lines,  and has a suggested  retail  price  ranging  from
approximately   $8,000  to  $70,000.   The  system  incorporates   fully-digital
processing  and  transmission  to the  desktop  and  several  open  architecture
interfaces  which  allow the  system to be  integrated  with and  controlled  by
attached personal computers (PCs) and workstations. The system incorporates over
one million lines of proprietary,  object-oriented C++ software developed by the
Company, which facilitates upgrades and incorporation of additional features and
functionality.

   The Company  recently  announced the  introduction  of AXXESS  version 3.0, a
system that expands the system  capacity to 256  telephones  and trunk lines and
enhances the open architecture capabilities of the system. In addition,  version
3.0 will port the  software  to faster  microprocessors,  which is  expected  to
permit the AXXESS system to continue to expand and to enhance the  functionality
and  performance  of these larger  systems as a customer's  system  requirements
increase.  Commercial  shipments  are expected to begin in the third  quarter of
1995.

   AXXESS "Executive" telephones incorporate  user-friendly,  6x16 character LCD
displays  with menu keys that  permit  the user to  select  from  multiple  menu
choices  or  access  additional  menu  screens.  AxxessoryTalk,   the  Company's
integrated voice processing  application,  permits pushbutton selection of voice
processing  commands  appearing  on the LCD display,  as well as  voice-prompted
selections through the telephone keypad.  The system is multi-lingual,  offering
multiple voice prompts and LCD displays and allowing the user to switch from one
language to the other.  The Company  expects to add additional  languages in the
future.

   The AXXESS system supports  several open  architecture  interfaces that allow
external  computers to interact and control the AXXESS system  through  industry
standard   interfaces.   The  AXXESS  system  supports  an  RS-232  system-level
interface,  an RS-232  Hayes-based  desktop interface and a Windows Dynamic Data
Exchange (DDE) interface through the  AxxessoryConnect  product. The Company has
Developer Toolkits available that include the detailed interface specifications,
application   notes  and  development  tools  to  assist  third  party  software
developers to develop  vertical  market  applications  for the AXXESS  products.
AXXESS   applications   include  database  look-up  (which  utilizes   caller-ID
information to retrieve customer  information  automatically from a computerized
database),  automated  attendant,  call center  applications,  interactive voice
response,  automatic call  distribution  (which queues and prioritizes  incoming
calls) and call accounting  (which permits the monitoring of telephone usage and
toll cost). The Company recently  announced  support of the Microsoft  Telephone
Application Programming Interface (TAPI) in AxxessoryConnect  version 2.0, which
is currently  scheduled for release in the third quarter of 1995, and support of
the Novell Telephony Services Application  Programming Interface (TSAPI),  which
is currently  scheduled  for release in the fourth  quarter of 1995.  The AXXESS
system is  managed  through a  Windows-based  interface  on a PC, to  facilitate
installation, system configuration and programming.

                                       18



<PAGE>
   The AXXESS  system  utilizes  advanced  software  to  configure  and  utilize
real-time DSP  semiconductor  components  incorporated into the system hardware.
The use of DSPs  and  related  software  lowers  system  costs,  permits  higher
functionality  and  increases  system  flexibility.  For  example,  DSPs  can be
configured by the system manager for different  combinations  of  speakerphones,
conference   capabilities   and  other   DSP-based   facilities.   The  system's
speakerphones incorporate full-duplex technology, which permits the telephone to
transmit in both  directions  at the same time without the necessity to override
one speaker's voice to prevent feedback interference.

   The AXXESS  software  is written in a  high-level,  object-oriented  language
which can operate on many commonly used microprocessors.

   Inter-Tel  Axxent.  The Company  recently  announced the  introduction of the
Inter-Tel  Axxent  telephone  system,  which is  expected  to  begin  commercial
shipment in the third quarter of 1995. The Inter-Tel Axxent system  incorporates
fully-digital  processing  and  transmission  to the desktop  and  several  open
architecture  interfaces.  Small businesses are demanding  additional  telephony
applications  such as  voicemail,  speakerphones,  conferencing  and  caller ID.
Inter-Tel  Axxent  is  designed  to  bring  many of the  advanced  features  and
functionality of the AXXESS system to smaller  installations on a cost-effective
basis  while   enabling   users  to  migrate  to  an  AXXESS   system  as  their
telecommunications needs evolve.

   Inter-Tel  Axxent  supports a total of 4 to 16 telephones  and 8 trunk lines,
and is expected to have a suggested  retail  price  ranging  from  approximately
$3,000 to $13,000. Inter-Tel Axxent system telephones,  like those of the AXXESS
system,  incorporate user-friendly LCD displays with menu keys. Inter-Tel Axxent
contains  the  same  open  architecture   interfaces  as  AXXESS,  which  permit
integrated  connection  to a PC or  workstation  and  enable  a  number  of  CTI
features.  The  Inter-Tel  Axxent  system is housed in a standard  PC  mid-tower
chassis, which is expected to enhance the upgradeability of the system.

   IMX  1224/2460,  IMX 256 and IMX 416/832.  The IMX line of products  offers a
broad range of features  including  extensive call control and system management
capabilities.  The analog IMX 1224/2460  systems support up to 60 telephones and
24 trunk lines,  with a modular  design that allows  capacity to be increased in
increments  of 6  telephones  and 6 trunk  lines.  The  digital  IMX 256 and IMX
416/832  systems  are  currently  the  Company's  largest  systems.  The IMX 256
supports  as many as 256  ports,  which may be  allocated  by the end user among
telephones  and trunk lines in order to best meet the end user's needs.  IMX 416
supports up to 416 ports and the IMX 832  supports up to 832 ports.  Each of the
IMX 256, IMX 416 and IMX 832 is expandable using  insertable  modules (which are
common to each of these platforms) in increments of 8 or 16 telephones,  8 trunk
lines or 24  digital-connection  T-1 trunk lines. The suggested retail price per
system of the IMX 1224/2460  ranges from  approximately  $5,000 to $30,000,  the
suggested  retail  price per  system of the IMX 256  ranges  from  approximately
$25,000 to $75,000, and the suggested retail price per system of the IMX 416/832
ranges from approximately $40,000 to $200,000.

   GLX and GLX+/GMX 48. The Company's GLX and GLX+ analog  product lines support
up to 12  telephones  and 6 outside  trunk  lines.  They are  designed for small
businesses such as restaurants, shops and professional offices. The GLX and GLX+
systems  feature  internal  speakerphones,  call  forwarding  capability  and an
optional data port for modems and data connections. In addition, the GLX+ has an
LCD display and supports single line telephones and voice processing.

   The analog GMX 48 supports up to 48 telephones and 24 trunk lines. The system
is modular and permits  expansion  in  increments  of 8  telephones  and 4 trunk
lines.  The GMX product offers many features found on larger systems,  including
advanced  messaging  capabilities.  The GMX 48 is used by professional  offices,
manufacturing  operations,  large retail stores and financial institutions.  The
Company sells these systems  primarily through dealers and direct sales offices.
The  suggested  retail  price per  system of the GLX ranges  from  approximately
$1,500 to $5,000;  the suggested  retail price per system of the GMX ranges from
approximately $3,000 to $20,000.

                                       19

   Product  Features.  The Company's  telephone systems provide a broad range of
standard features,  including automated  attendant,  call forward,  off premises
notification  and day/night toll  restrictions.  The AXXESS system  incorporates
more advanced features, certain of which are described below.

   o  Automatic call distribution  (ACD).  Incoming calls are distributed evenly
      over a service group and customers hear pre-recorded announcements telling
      them they will be handled by the next  available  agent.  ACD  supervisors
      receive real time and historical reports on the status of the group(s).

   o  Automatic  database retrieval ("screen pop"). Based on the calling number,
      the system accepts a modem tone prior to accepting the customer call. This
      modem tone is used to identify  the  customer  and to retrieve  (or "pop")
      information from the customer's database to the user's computer screen.

   o  Multi-lingual feature operation.  The AXXESS system can be readily adapted
      to other languages by changing the voiced prompts and the menus on the LCD
      displays.   The  AXXESS  system  currently  offers  English  and  Japanese
      versions.

   o  Caller  ID. In areas  where  this  service  is  offered  by the  telephone
      utility,  the AXXESS LCD display enables the name and telephone  number of
      the calling party to be displayed to the called party.

   o  Integrated  voice  processing.   Tight   integration   between  the  voice
      processing  system and the telephone  system allows  telephones to display
      each waiting  message and provides a means for the user to randomly select
      among messages by pressing a single button. Features such as play, record,
      pause,  skip and delete appear on the LCD display of the AXXESS  executive
      telephone for rapid access and instant processing.

   o  Personal  computer  programming.  Allows  service  personnel  to connect a
      laptop  computer  and program the system using a Microsoft  Windows  based
      graphical user interface.

   o  Integrated  SMDR/SMDA.  Systems feature an internal Station Message Detail
      Recording (SMDR) report  generator which summarizes  calling patterns in a
      variety of ways to assist in management of system usage.  Further  reports
      may be generated by  transferring  call details to a specialized  computer
      using the SMDR.  Station Message Detail  Accounting (SMDA) enables the end
      user to format and manipulate the information received by the system.

   o  Single  database  management.   Many  systems  require  attached  computer
      applications  such as voice  processing and call accounting  systems to be
      programmed and administrated  separately.  The single database  management
      capability  of the AXXESS system allows the installer to program a variety
      of  options  on  both  the   telephone   system  and   attached   computer
      simultaneously in a single programming session.

 CTI AND SOFTWARE PRODUCTS

   The Company has  developed the  AxxessoryConnect  software  application  that
provides a Windows interface for the AXXESS  telephones.  The enhanced graphical
interface uses the AXXESS Desktop  Interface and provides DDE and Microsoft TAPI
interfaces to allow integration with other Windows  applications.  Using the DDE
interface, customer records can be automatically displayed on the PC screen when
a new call starts to ring the telephone. The AxxessoryConnect application allows
integration  with many  personal  information  managers  and contact  management
applications such as DayTimer Organizer, Lotus Organizer and Commence.

   The Company has also developed the Inside Track call accounting  application.
The  Inside  Track  application  is a Windows  program  that  works  with all of
Inter-Tel's  telephone  systems and provides  detailed call  accounting  reports
which  allow  customers  to track  telephone  costs,  monitor for toll fraud and
abuse, and allocate costs across departments.

 VOICE PROCESSING PRODUCTS AND APPLICATIONS

   The Company has developed AxxessoryTalk, its own voice processing product for
the AXXESS system.  This voice processing  product is integrated with the AXXESS
system via the Company's AxxessLink  software.  It supports up to 500 mailboxes,
up to 16 simultaneous voice ports and up to 30 hours of messages.
The system also incorporates a paging application.

                               20


<PAGE>

   The Company has incorporated  the features of AxxessoryTalk  into its new IVX
500 voice processing  platform.  This product provides enhanced voice processing
capabilities to the GLX/GMX/IMX  products.  The Company's  products also support
interactive voice response applications through industry-standard protocols.

   The Company recently announced  AxxessoryTalk  version 3.0, which runs on the
OS/2 operating system and supports 500 mailboxes and up to 32 simultaneous  port
connections.  AxxessoryTalk  3.0 also  supports a Fax Back  feature  that allows
customers to call in and have documents faxed back to them. Commercial shipments
are expected to commence in the third  quarter of 1995.  Both the  AxxessoryTalk
and IVX 500 products include the open, industry-standard  multi-vendor interface
protocol (MVIP). MVIP is a standard for connecting  multi-vendor PC-based boards
in voice processing, data switching and video applications.

 OTHER SERVICES AND PRODUCTS

   
   Long  Distance  Calling  and  Network  Services.  The  Company,  through  its
Inter-Tel  NetSolutions,  Inc.  subsidiary,  resells a variety of  popular  long
distance  calling  services,   including  domestic  and  international   calling
services,   800  calling   services,   dedicated   services,   voice  and  video
conferencing,  customized  billing  and a  variety  of  other  telecommunication
services.  The  Company  believes  that  certain  of its  customers  desire  the
convenience of acquiring long distance  calling services through the same vendor
that the customer uses to purchase its other  telephony  equipment and services.
The Company  currently resells long distance services pursuant to contracts with
three of the six largest U.S.  long  distance  carriers,  and is  negotiating  a
similar  contract with a fourth.  These  contracts  typically  have a multi-year
term,  during which the Company's prices are relatively  fixed, and have minimum
use  requirements.  There can be no  assurance  that the  Company  will meet its
minimum use commitments,  will be able to negotiate lower rates with carriers in
the  event of any  decrease  in end user  rates  or will be able to  extend  its
contracts with long distance  carriers on prices  favorable to the Company.  The
Company is currently tariffed to resell long distance services in 20 states, and
intends to become tariffed in all 50 states.
    

   The Company markets its long distance  calling and network  services  through
its direct  sales  force.  The Company  provides  training to the sales force to
increase the knowledge and expertise required to sell long distance services.

   Inter-Tel's  sales force  sells long  distance  calling and network  services
together  with its other  products  to the same  customers,  which  the  Company
believes offers it a competitive advantage over certain of its competitors.  The
Company also allows selected  dealers to sell long distance  calling and network
services.  The  Company  utilizes a  combination  of long  distance  carriers to
provide  competitive  rates and services for dealers and  customers  using these
long distance network services.  The Company seeks to increase the number of its
long distance calling customers and the volume of its long distance services, in
order to obtain more favorable pricing from its vendors.

   Leasing  Services.  The  Company  offers its  Totalease  program  through its
Inter-Tel Leasing,  Inc. subsidiary.  Totalease enables an end user to acquire a
full range of telephony systems, applications, maintenance and support services,
as well as  lease  financing,  from a  single  vendor.  The  Totalease  contract
provides a total  system  solution to the customer at a set monthly  cost,  with
system expansion available at predictable additional fees. The typical Totalease
contract  has a term of 60  months,  with the  customer  entitled  to renew at a
specified  price for up to an  additional  36  months.  The  Company  intends to
introduce  single  invoice  billing,  which will enable  customers to manage all
telephone related payables,  including lease payments,  maintenance obligations,
upgrades,  system  expansion and long distance calling services through a single
monthly bill from Inter-Tel.

   Inter-Tel  also  offers a full  line of lease  purchase  financing  to enable
customers to acquire Inter-Tel equipment.  This leasing is available through the
Company's direct offices and dealers. The lease terms range from 24 to 84 months
with $1.00 and fair market  value  purchase  options.  By offering  this type of
financing to acquire Inter-Tel equipment, the customer is able to lease directly
from the manufacturer. In

                                       21



<PAGE>
addition,  Inter-Tel,  or the Inter-Tel dealer, gains an additional  competitive
advantage in the marketplace by maintaining a close customer  relationship.  The
payment  streams  from  these  leases  are sold from  time to time to  financial
institutions in conjunction with the leases from the Totalease program.

   Other Products.  Inter-Tel established its factored products division in 1994
to  provide  "single  sourcing"  of the  industry's  leading  telecommunications
products.  The factored  products  division  resells products that Inter-Tel has
endorsed as the leading  communications  peripherals  needed in many  day-to-day
functions.  Many of these products  interface with Inter-Tel  telephone systems.
Inter-Tel's product selection consists of voice and video conferencing,  battery
backup,  headsets, surge protection,  paging equipment,  wireless communications
and data  multiplexers.  The Company  represents  leading  manufacturers such as
Compression Labs, Inc.,  Tandberg Telecom,  American Power Conversion Corp., ACS
Enterprises,  Inc., Ditek Industries,  Inc., Valcom,  Inc., Kentrox  Industries,
Inc. and other leading telecommunications vendors.

SALES AND DISTRIBUTION

   The Company has developed a network of direct sales offices and dealers which
sells the Company's  products.  In the United States,  the Company has 25 direct
sales offices and a growing network of hundreds of dealers who purchase  systems
directly from the Company.  Dealers are typically located in geographic areas in
which the Company does not maintain direct sales offices.  The Company is in the
process of expanding its international dealer network.

   The Company  believes  that its success  depends in part upon the strength of
its  distribution  channels  and the ability of the  Company to  maintain  close
access to end user  customers.  In recent  periods,  the  Company  has sought to
improve its access to end user customers by effecting strategic  acquisitions of
resellers of telephony products and services in markets in which the Company has
existing  direct  sales  offices  and in other  strategic  markets.  The Company
intends to further expand its  distribution  channels by selling  certain of its
CTI  products  and  services  through  computer  equipment  dealers and software
resellers.

   The Company  typically enters into  non-exclusive  contracts with its dealers
for a term of one or more years.  Inter-Tel generally provides support and other
services to the dealer  pursuant to the terms of the  agreement.  The agreements
often include  requirements that the dealer meet or use its best efforts to meet
minimum  annual  purchase  quotas.  The  Company's  experience  is that  dealers
maintain low inventories of the Company's products and, accordingly, the Company
has  experienced  insignificant  stock  rotation  returns  and price  protection
credits to date.  The Company faces  intense  competition  from other  telephone
system and voice processing system manufacturers for its dealers' attention,  as
most of the Company's  dealers carry  products  which compete with the Company's
products.  There can be no  assurance  that any such dealer will not promote the
products  of the  Company's  competitors  to  the  detriment  of  the  Company's
products.  The loss of any significant dealer or group of dealers,  or any event
or condition  adversely  affecting the Company's  dealer  network,  could have a
material  adverse effect on the Company's  business and operating  results.  See
"Risk Factors--Reliance on Dealer Network."

   International  sales have not been  significant  to date,  and have been made
through the Company's  United Kingdom and Japan  subsidiaries.  In order to sell
its products to customers in other countries, the Company must comply with local
telecommunications  standards.  The AXXESS system can be readily altered through
software  modifications,  which the Company believes will facilitate  compliance
with local  regulations.  In addition,  the AXXESS  system has been  designed to
support  multi-lingual   functionality,   and  currently  supports  English  and
Japanese.  The Company is presently  establishing  dealer  networks in Japan and
Asia and is expanding its dealer network in the United  Kingdom and Europe.  The
Inter-Tel   Axxent   system   is   currently   awaiting    regulatory   approval
internationally. International sales are subject to a number of risks, including
changes in foreign  government  regulations  and  telecommunications  standards,
export  license   requirements,   tariffs  and  taxes,   other  trade  barriers,
fluctuations  in currency  exchange  rates,  difficulty in  collecting  accounts
receivable, difficulty in staffing and managing foreign operations and political
and economic  instability.  Fluctuations in currency  exchange rates could cause
the

                                       22



<PAGE>
Company's  products  to become  relatively  more  expensive  to  customers  in a
particular  country,  leading to a reduction in sales or  profitability  in that
country. In addition,  the costs associated with developing  international sales
may not be offset by increased sales in the short term, or at all.

CUSTOMER SERVICE AND SUPPORT

   The Company  believes  that  service and support is a critical  component  of
customer  satisfaction  and the success of the Company's  business.  Inter-Tel's
telecommunications  expertise enables it to provide its customers with a variety
of systems  consulting  services.  The Company  assists  customers in evaluating
their system requirements and in integrating the hardware,  software and network
components of the customers' systems.

   The Company operates a Technical Support "hotline" to provide a full range of
telephone support to its distributors,  dealers and end user customers,  free of
charge through a toll free number.  The Company also provides  on-site  customer
support and, through remote diagnostic procedures, has the ability to detect and
correct system problems from its Technical Support facilities.

   Information taken from customer call records allows feedback into Inter-Tel's
Quality First  continuous  improvement  process,  thus  providing a road map for
continuous product and service enhancements. Each direct sales office is given a
periodic  service  activity report  summarizing the reasons that technicians are
asking for assistance  and common issues that give rise to technical  inquiries.
This  allows  them to analyze  trends in their  service  operations  and provide
better customer service.

RESEARCH AND DEVELOPMENT

   The Company's  research and  development  efforts over the last several years
have been focused  primarily on development and improvement of the AXXESS system
as well as the  development  of CTI and  other  advanced  applications.  Current
efforts are related to porting AXXESS software to smaller (Inter-Tel Axxent) and
larger  (AXXESS  version  3.0)  versions  of  hardware,   supporting  additional
industry-standard open architecture  interfaces (including TAPI and TSAPI, among
others),  supporting  facsimile  features  using MVIP,  developing  multi-system
networking  capabilities,  developing  fiber  optic  interfaces  on  the  AXXESS
product,  enhancing the  functionality of the  AxxessoryTalk  and IVX-500 (voice
processing)  products,   adapting  the  AXXESS  and  AxxessoryTalk  products  to
international markets and developing additional switch applications and features
that enhance the integration with advanced NetSolutions services and products.

   The Company had a total of 91 personnel  engaged in research and  development
as of June 30, 1995. Research and development  expenses were $3.9 million,  $4.1
million,  $4.5  million and $2.9 million in 1992,  1993,  1994 and the first six
months of 1995, respectively.

MANUFACTURING

   The Company manufactures substantially all of its systems through third party
subcontractors  located in the United States,  the  Philippines and the People's
Republic  of China.  These  subcontractors  use both  standard  and  proprietary
integrated  circuits  and other  electronic  devices and  components  to produce
telephone  switches,  telephones  and printed  circuit  boards to the  Company's
engineering  specifications and designs. The suppliers also inspect and test the
equipment  before  delivering  them  to  the  Company,  which  performs  systems
integration,   software  loading,  final  testing  and  shipment.  Inter-Tel  is
increasing  its  use  of  domestic   subcontractors.   Varian,  a  multinational
electronics  company,  currently  manufactures  a  significant  portion  of  the
Company's  products,  including  substantially all of the printed circuit boards
used in the AXXESS and Inter-Tel  Axxent  systems,  at Varian's  Tempe,  Arizona
facility.  If Varian or any of the Company's other  manufacturers were unable or
unwilling to manufacture the Company's products in the future, the Company could
experience substantial delays in finding alternative sources, which could have a
material adverse effect on the Company's business and operating results.

   While the Company maintains written agreements with its principal  suppliers,
none of such  agreements  requires the suppliers to provide fixed  quantities of
components  or finished  goods at set prices on a long term  basis.  The Company
provides rolling forecast schedules to its suppliers and revises the forecast on
a periodic basis.

   Foreign  manufacturing  facilities  are  subject to  changes in  governmental
policies,  imposition  of tariffs  and import  restrictions,  and other  factors
beyond  the  Company's  control.  Certain  of  the  microprocessors,  integrated
circuits and voice processing  interface cards used in the Company's systems are
currently  available from a single or limited  sources of supply.  The Company's
reliance on third party  manufacturers  involves a number of  additional  risks,
including reduced control over delivery schedules,  quality assurance and costs.
From  time to  time,  the  Company  has  experienced  delays  in the  supply  of
components  and finished  goods,  and there can be no assurance that the Company
will not experience such delays in the future. Any delay in delivery or shortage
of supply of  components  or  finished  goods from  existing  suppliers,  or the
Company's  inability to develop in a timely  manner  alternative  or  additional
sources  if and  when  required,  could  materially  and  adversely  affect  the
Company's  business and operating  results.  There can be no assurance  that the
Company  will be able to continue  to obtain  components  or  finished  goods in
sufficient  quantities or quality or on favorable  pricing and delivery terms in
the  future.  See "Risk  Factors--Dependence  Upon  Contract  Manufacturers  and
Component Suppliers." 
    

QUALITY

   The Company  believes that the quality of its systems,  customer  service and
support,  and other aspects of its organization is a critical element of meeting
the needs of its  customers.  Through its Quality First  continuous  improvement
process,  Inter-Tel implements quality processes throughout its operations.  The
Company has established  formal procedures to ensure  responsiveness to customer
requests,  to monitor response times and to measure customer  satisfaction.  The
Company has also established means by which all end users,  including  customers
of the Company's  resellers,  can make product enhancement  requests directly to
the  Company.  The Company  supports its dealers  through an extensive  training
program at the  Company's  facility and at dealer sites,  a toll free  telephone
number for sales and technical  support and the provision of end user  marketing
materials.  The Company  typically  provides one to two year  warranties  on its
systems to end users. In manufacturing,  the Company  continuously  monitors the
quality of the products  produced on its behalf by the  Company's  manufacturing
subcontractors,   and  is  extending  the  Company's  Quality  First  continuous
improvement process to its suppliers.

COMPETITION

   The market for the Company's  telephone system products is highly competitive
and in recent periods has been  characterized by pricing  pressures and business
consolidations.  The Company's  competitors  include AT&T and NorTel, as well as
Comdial, Executone, Mitel, Panasonic, ROLM, Toshiba and others. The Company also
competes  against the RBOCs,  which offer systems produced by one or more of the
aforementioned  competitors  and also offer Centrex  systems in which  automatic
calling  facilities  are provided  through  equipment  located in the  telephone
company's central office.  Competition by the RBOCs could increase significantly
if the  RBOCs  are  granted  the  right to  manufacture  telephone  systems  and
equipment  themselves  and/or to bundle  the sale of  equipment  with  telephone
calling  services,  activities  which to date  they have  been  restricted  from
undertaking.  Recent legislative initiatives would have the effect of increasing
competition  from the RBOCs.  Key  competitive  factors in the sale of telephone
systems and related  applications include  performance,  features,  reliability,
service and support, name recognition, distribution capability and price.

   In the market for voice  processing  applications,  including voice mail, the
Company  competes  against  Centigram,   Octel,  Active  Voice,  AVT  and  other
competitors,  including telephone systems manufacturers such as AT&T, NorTel and
ROLM, which offer  integrated voice processing  systems under their own label as
well as through various OEM arrangements.  Certain of the Company's  competitors
may achieve  marketing  advantages by bundling their voice processing  equipment
with sales of telephone systems, or by designing their telephone systems so that
they  do not  readily  integrate  with  independent  voice  processing  systems.
Inter-Tel expects that the development of industry  standards and the acceptance
of open  systems  architectures  in the  voice  processing  market  will  reduce
technical  barriers  to market  entry  and lead to  increased  competition.  Key
competitive  factors  in the  sale  of  voice  processing  applications  include
performance, features, name recognition and price.

                                       24



<PAGE>
   In the market for long distance services,  the Company competes against AT&T,
MCI, Sprint and other suppliers,  certain of which also supply the long distance
calling and network  services  that the Company  resells.  Although  the Company
acquires a variety of long distance  calling  services in bulk from certain long
distance  carriers,  there can be no assurance  that the Company will be able to
purchase long distance  calling  services on favorable terms from one or more of
such providers in the future. In addition, a substantial majority of prospective
new long  distance  customers for the Company  currently  purchase long distance
calling services from the Company's competitors. The Company believes that it is
likely to face  increased  competition  in the long  distance  calling  services
market to the  extent  that  telecommunications  deregulation  enables  RBOCs to
supply long distance calling and network services or enables RBOCs and others to
bundle long  distance,  local  telephone and wireless  services.  Moreover,  the
Company  expects to face  increased  competition  in the  future  because of low
technical  barriers  to entry will allow new market  entrants.  Key  competitive
factors in the sale of long distance  services include name  recognition,  price
and performance.

   Many of the Company's  competitors have  significantly  greater financial and
technical   resources,   name   recognition   and  marketing  and   distribution
capabilities  than the  Company.  The  Company  expects  that  competition  will
continue to be intense in the markets addressed by the Company, and there can be
no  assurance  that the  Company  will be able to  compete  successfully  in the
future.

INTELLECTUAL PROPERTY RIGHTS

   In addition to the factors  discussed above, the Company's ability to compete
successfully  depends  on its  ability  to protect  the  proprietary  technology
contained in its products.  The Company has no patents and relies principally on
copyright  and trade  secret  law and  contractual  provisions  to  protect  its
intellectual property. There can be no assurance that any copyright owned by the
Company will not be  invalidated,  circumvented or challenged or that the rights
granted thereunder will provide competitive advantages to the Company.  Further,
there can be no  assurance  that others will not develop  technologies  that are
similar or superior to the  Company's  technology  or  duplicate  the  Company's
technology.  As the Company  expands  its  international  operations,  effective
intellectual  property  protection  may be  unavailable  or  limited  in certain
foreign countries. There can be no assurance that the steps taken by the Company
will prevent misappropriation of its technology.  Litigation may be necessary in
the future to enforce the Company's intellectual property rights, to protect the
Company's trade secrets,  to determine the validity and scope of the proprietary
rights of others,  or to defend  against claims of  infringement  or invalidity.
Such litigation could result in substantial costs and diversion of resources and
could have a material  adverse  effect on the  Company's  business and operating
results.

   From  time  to  time,  the  Company  is  subject  to   proceedings   alleging
infringement  by the Company of intellectual  property rights of others.  If any
such claim is  asserted  against the  Company,  the Company may seek to obtain a
license under the third party's  intellectual  property rights.  There can be no
assurance that a license will be available on terms acceptable to the Company or
at all. In the alternative,  the Company could resort to litigation to challenge
any such claim, and the Company is currently engaged in one such proceeding. See
"Business--Legal Proceedings." Any such proceedings could require the Company to
expend  significant  sums in  litigation  and could  require  the Company to pay
significant damages,  develop  non-infringing  technology or acquire licenses to
the technology which is the subject of the asserted  infringement,  any of which
could have a material  adverse  effect on the  Company's  business and operating
results. See "Risk Factors--Product Protection and Infringement."

EMPLOYEES

   As of June 30, 1995, the Company had a total of 896 employees,  including 237
engaged in sales,  marketing and customer support, 92 in quality,  manufacturing
and related  operations,  91 in research and  development  and 36 in finance and
administration.  The  Company's  future  success will depend upon its ability to
attract,  retain  and  motivate  highly  qualified  employees,  who are in great
demand. None of the

                                       25



<PAGE>

Company's  employees  is  represented  by a labor  union  with  respect to their
employment by the Company,  and the Company believes that its employee relations
are good. See "Risk Factors--Dependence on Key Personnel."

PROPERTIES

   The Company  maintains  its corporate  headquarters  in an 85,000 square foot
building located in Chandler,  Arizona pursuant to a lease that expires in 2008.
The Company also leases sales and support  offices in a total of 25 locations in
the United States and two locations  overseas.  The Company  expects to move its
corporate offices to another location in Phoenix,  Arizona in the fourth quarter
of 1995.  Following such move, the Company  believes that its facilities will be
adequate to meet its current needs and that additional or alternative space will
be available as necessary in the future on commercially  reasonable  terms.  See
"Risk  Factors--Management  of Growth;  Implementation of Management Information
Systems."

   

   The Company is currently  engaged in soil  remediation at an office and hotel
complex  previously  owned by the Company.  While the property was sold in 1993,
the Company  remains  liable for certain  environmental  matters  related to the
property.  A groundwater  investigation  of such  property is ongoing.  Based on
estimates  provided by  specialists,  the Company  has  established  a financial
reserve which it believes is adequate.  Although no assurances can be given, the
Company  believes  that the cost to it of  continuing  remedial  efforts on this
property will not have a material  adverse  effect on the Company's  business or
financial condition.
    

LEGAL PROCEEDINGS

   The Company is involved  from time to time in  litigation  incidental  to its
business.  The Company believes that the outcome of current  litigation will not
have a material  adverse  effect upon its  results of  operations  or  financial
condition and will not disrupt the normal operations of the Company.

                                 UNDERWRITING

   Montgomery  Securities,  Donaldson,  Lufkin & Jenrette Securities Corporation
and Sutro & Co. Incorporated (the "Underwriters") have severally agreed, subject
to the terms and conditions set forth in the Underwriting Agreement, to purchase
from the  Company and the  Selling  Shareholders  the number of shares of Common
Stock  indicated  below opposite their  respective  names at the public offering
price  less  the  underwriting  discount  set  forth on the  cover  page of this
Prospectus.  The  Underwriting  Agreement  provides that the  obligations of the
Underwriters  are  subject  to  certain  conditions  precedent,   and  that  the
Underwriters are committed to purchase all of such shares if any are purchased.

   The Underwriters  have advised the Company and the Selling  Shareholders that
they initially  propose to offer the shares of Common Stock to the public on the
terms set forth on the cover page of this Prospectus. The Underwriters may allow
to  selected  dealers a  concession  of not more than $0.49 per  share,  and the
Underwriters may allow, and such dealers may reallow, a concession not more than
$0.10 per share to certain  other  dealers.  After the  offering,  the price and
other  selling  terms may be changed by the  Underwriters.  The Common  Stock is
offered  subject to receipt and acceptance by the  Underwriters,  and to certain
other conditions, including the right to reject orders in whole or part.

    

   A Selling Shareholder has granted an option to the Underwriters,  exercisable
during the 30-day period after the date of this Prospectus,  to purchase up to a
maximum of 427,500  additional shares of Common Stock to cover  over-allotments,
if any,  at the same  price  per  share as the  initial  2,850,000  shares to be
purchased by the Underwriters. To the extent that the Underwriters exercise this
option,  each  of  the  Underwriters  will  be  committed,  subject  to  certain
conditions,  to  purchase  such  additional  shares  in  approximately  the same
proportion as set forth in the above table.  The  Underwriters may purchase such
shares only to cover over-allotments made in connection with this offering.

   The  Underwriting  Agreement  provides  that the Company and certain  Selling
Shareholders  will  indemnify  the  Underwriters  against  certain  liabilities,
including  civil  liabilities  under the Securities Act of 1933, as amended (the
"Securities  Act"),  or will  contribute  to payments  the  Underwriters  may be
required to make in respect thereof.

   
   The  Company's  executive  officers  and the Selling  Shareholders,  who will
collectively  beneficially own an aggregate of approximately 3,300,000 shares of
Common Stock  following  the  offering  (2,900,000  shares if the  Underwriters'
over-allotment  option is  exercised  in full),  have  agreed  that  without the
consent  of  the  Underwriters  acting  jointly,  they  will  not,  directly  or
indirectly offer,  sell,  contract to sell or otherwise dispose of any shares of
Common Stock or any securities  convertible into or exchangeable  therefor for a
period of 90 days from the date of this Prospectus. The Company has agreed that,
for a period of 90 days from the date of this  Prospectus,  it will not, without
the written consent of the Underwriters acting jointly,  directly or indirectly,
offer, sell, contract to sell or otherwise dispose of any shares of Common Stock
or any  securities,  convertible or  exchangeable  therefor,  subject to limited
exceptions. 
    

   From time to time,  certain  of the  Underwriters  or their  affiliates  have
provided,  and may  continue  to  provide,  investment  banking  services to the
