ITEM 2. Acquisition or Disposition of Assets

        On December 31, 1997, GST Telecommunications, Inc., a federally
chartered Canadian corporation ("GST"), GST USA, Inc., a Delaware corporation
("GST USA"), and World Access, Inc. ("World Access") entered into a Stock
Purchase Agreement (the "Purchase Agreement"), pursuant to which World Access
has agreed to purchase from GST USA (hereinafter referred to as the
"Acquisition") 5,113,712 shares of the common stock of NACT Telecommunications,
Inc. ("NACT") held by GST USA (hereinafter referred to as the "Shares"),
representing approximately 63% of the outstanding shares of NACT common stock,
$.01 par value per share (the "NACT Common Stock"). 

        On February 27, 1998, the Acquisition was consummated and World Access 
paid to GST USA cash in the amount of $59,662,956 and delivered to GST USA
1,429,907 shares of World Access common stock (the "World Access Common Stock").
The foregoing summary of the Acquisition is qualified in its entirety by
reference to the terms of the Purchase Agreement and the exhibits thereto, which
are included as Exhibit 2.1 hereto.



                                        1
<PAGE>   3
         In connection with the consummation of the Acquisition, W. Gordon 
Blankstein, Stephen Irwin, Robert Olson and Clifford V. Sander, each designees
of GST USA, resigned from NACT's Board of Directors and Steven A. Odom, Hensley
E. West, Mark A. Gergel and Scott N. Madigan, each executive officers of World 
Access, were appointed to fill the vacancies thus created. 

         The consideration paid pursuant to the Purchase Agreement was
determined as a result of negotiations between World Access and GST and the
Acquisition was approved by the boards of directors of World Access, GST and
NACT. Prior to the Acquisition, neither World Access nor any of its affiliates,
directors or officers, nor any associate of any such director or officer, had
any relationship with GST, GST USA or NACT.

         Between November 12, 1997 and December 9, 1997, World Access purchased
an aggregate of 355,000 shares of NACT Common Stock in open market purchase
transactions (the "Open Market Purchase"). Accordingly, after the completion of
the Acquisition World Access now owns approximately 68% of the outstanding NACT
Common Stock.

        On February 24, 1998 World Access entered into a merger agreement with
NACT pursuant to which World Access agreed to acquire all of the shares of NACT
Common Stock not already then owned by World Access or GST USA.  Pursuant to the
terms of the merger agreement, each share of NACT Common Stock will be converted
into shares of World Access Common Stock having a value of $17.50 per share
based on the average of the daily closing price of the World Access Common Stock
on the NASDAQ National Market on each of the twenty consecutive trading days
ending with the third day immediately preceding the effective time of the merger
(the "Closing Price"), provided that if the Closing Price is more than $25.52,
then each share of NACT Common Stock will be converted into 0.6857 shares of
World Access Common stock, and if the Closing Price is less than $20.88, then
World Access can terminate the agreement. The merger agreement was negotiated on
behalf of NACT by a Special Committee of the NACT Board and has been approved by
the Boards of Directors of NACT and World Access.  In addition, NACT has
received a fairness opinion with respect to the merger from NationsBanc
Montgomery Securities LLC.  The merger is subject to, among other things, the
approval of the NACT stockholders and the satisfaction of certain other
customary conditions.

                          Notes to Financial Statements

                       September 30, 1997, 1996, and 1995



(1)      Summary of Significant Accounting Policies

         (a)      Organization and Description of Business

                  NACT Telecommunications, Inc. (the "Company") designs,
                  develops and manufactures advanced telecommunications
                  switching platforms with integrated applications software and
                  network telemanagement capabilities. The Company's customers
                  include long distance carriers, prepaid debit (calling) card
                  and prepaid cellular network operators, international call
                  back/reorigination providers and other specialty
                  telecommunications service providers.

                  From September 1993 through September 30, 1995, GST USA, Inc.
                  ("GST USA") acquired all of the issued and outstanding common
                  stock of the Company. This acquisition was accomplished
                  through a series of purchases of newly issued shares and the
                  shares of principal stockholders of the Company. As a result
                  of these transactions, the Company became a wholly owned
                  subsidiary of GST USA. GST USA accounted for the acquisition
                  using the purchase method of accounting. The excess of the
                  purchase price over the fair value of the assets acquired
                  totaled $6,912,322 and was assigned by GST USA as product
                  support contracts, software development costs, and goodwill.
                  These amounts are included in the accompanying balance sheet
                  as intangible assets.

                  In February 1997, the Company closed an initial public
                  offering (IPO) of 3,000,000 shares of common stock with
                  2,000,000 sold by the Company and 1,000,000 sold by GST USA.
                  Upon completion of the offering, GST USA ownership was reduced
                  to approximately 63 percent of the outstanding common stock of
                  the Company and, as such, GST USA continues to control the
                  Company. In connection with the IPO, the Company established a
                  par value of $.01 for common stock, increased the number of
                  common shares authorized to 25,000,000, and authorized
                  10,000,000, $.01 par value preferred shares.

                  On September 30, 1997, GST USA announced that it had retained
                  Hambrecht and Quist LLC to explore alternatives for monetizing
                  its 63 percent interest in the Company, including a potential
                  sale of some or all of the Company's capital stock to one or
                  more strategic investors.

         (b)      Wasatch International Network Services

                  The 1995 financial statements include the accounts of the
                  Company and its wholly-owned subsidiary Wasatch International
                  Network Services, Inc. ("Wins"), which commenced operations in
                  fiscal 1995 and had total assets, revenues, and net loss of
                  $316,455, $1,097,950 and $2,361, respectively, as of and for
                  the year ended September 30, 1995. All significant
                  intercompany transactions and balances were eliminated in
                  consolidation. On October 1, 1995, the Company transferred
                  ownership and operations of Wins to GST USA in the form of a
                  dividend at historical cost. From October 1, 1995 through
                  September 30, 1996, the Company provided carrier services to
                  GST USA for the Wins operation for which it received
                  $2,571,731. GST USA began providing its own carrier services
                  for Wins on October 1, 1996.

                          Notes to Financial Statements

         (c)      Cash and Cash Equivalents

                  The Company considers all highly liquid financial instruments
                  purchased with an original maturity to the Company of three
                  months or less to be cash equivalents. Cash equivalents
                  consist of money market accounts of $8,472,637 at September
                  30, 1997 and $125,785 at September 30, 1996.

         (d)      Inventories

                  Raw materials are valued at the lower of cost (first-in,
                  first-out) or market. Work-in-process and finished goods are
                  stated on the basis of accumulated manufacturing costs, but
                  not in excess of market (net realizable value). Refurbished
                  inventory is stated at the estimated selling price less
                  refurbishing costs, selling costs and a normal profit margin.
                  Management periodically reviews the selling price of the
                  refurbished inventory and records adjustments to the carrying
                  value, if any, in the period in which they occur.

                  Long-term inventory consists of component parts held in order
                  to provide support on existing customer equipment beyond one
                  year.

         (e)      Notes Receivable

                  Notes receivable are recorded at the principal amount
                  outstanding, net of an allowance for doubtful notes. The
                  allowance is an amount that management believes will be
                  adequate to absorb possible losses based on evaluations of
                  collectibility and prior loss experience. The evaluation takes
                  into consideration such factors specific problem loans, past
                  payment history, and current and anticipated economic
                  conditions that may affect the customers' ability to pay.

                  While management uses available information to recognize
                  losses on notes, changing economic conditions and the economic
                  prospects of the borrowers might necessitate future additions
                  to the allowance.

         (f)      Impaired Notes

                  Management, considers a note to be impaired when it is
                  probable that the Company will be unable to collect all
                  amounts due according to the contractual terms of the note
                  agreement. When a note is considered to be impaired, the
                  amount of the impairment is measured based on the present
                  value of expected future cash flows discounted at the note's
                  effective interest rate. Impairment losses are included in the
                  allowance for doubtful accounts through a charge to bad debt
                  expense. Cash receipts on impaired notes receivable are
                  applied to reduce the principal amount of such notes until the
                  principal has been recovered and are recognized as interest
                  income thereafter.

                          Notes to Financial Statements

         (g)      Property and Equipment

                  Property and equipment are stated at cost. Depreciation is
                  computed using the straight-line method for financial
                  reporting purposes. Depreciation is based upon the estimated
                  useful lives of individual classes of assets. The estimated
                  useful lives of the individual classes of assets are as
                  follows:

                           Building                               35 years
                           Furniture and equipment              7-10 years
                           Computer equipment                    3-7 years
                           Switch and testing equipment          3-7 years

         (h)      Intangibles

                  Intangibles include goodwill, software development costs,
                  customer lists, and product support contracts and are being
                  amortized on a straight-line basis over the estimated useful
                  lives of the respective assets.

         (i)      Software Development Costs

                  Software development costs are capitalized upon the
                  establishment of technological feasibility of the product.
                  Capitalization is discontinued when the product is available
                  for general release to customers. The Company capitalized
                  software development costs of $821,568, $419,154, and $162,025
                  in 1997, 1996, and 1995, respectively.

         (j)      Stock-Based Compensation

                  Effective October 1, 1996, the Company adopted the footnote
                  disclosure provisions of Statement of Financial Accounting
                  Standards No. 123, Accounting for Stock-Based Compensation
                  (SFAS 123). SFAS 123 encourages entities to adopt the fair
                  value based method of accounting for stock options or similar
                  equity instruments. However, it also allows an entity to
                  continue measuring compensation cost for stock-based
                  compensation using the intrinsic-value method of accounting
                  prescribed by Accounting Principles Board Opinion No. 25,
                  Accounting for Stock Issued to Employees (APB 25). The Company
                  has elected to continue to apply the provisions of APB 25 and
                  provide pro forma footnote disclosures required by SFAS 123.

         (k)      Revenue Recognition and Deferred Revenue

                  Revenue from product sales is recognized when the product is
                  shipped and the Company has no significant performance
                  obligations. Revenue from network carrier sales is recognized
                  as the related service is provided. Deferred revenue consists
                  of warranty payments billed or received in advance and
                  deposits related to future product sales. Warranty payments
                  are amortized over the period of the warranty agreement which
                  is typically one year.

                          Notes to Financial Statements

         (l)      Income Taxes

                  Through February 26, 1997, the Company was a member of a
                  controlled group which elected for federal income tax purposes
                  to file a consolidated tax return with GST USA. In accordance
                  with the tax sharing arrangement with GST USA, the Company
                  recorded the estimated income tax expense as if the Company
                  filed a tax return on a separate company basis using the asset
                  and liability method. GST USA agreed to make a capital
                  contribution to the Company in an amount that approximates the
                  Company's current federal income tax expense through February
                  26, 1997 in lieu of an intercompany payment for such taxes.
                  Pursuant to the tax sharing arrangement between the Company
                  and GST USA, the adjustment recorded to reconcile the
                  intercompany and equity accounts with regard to differences
                  between the estimated tax determined at year-end and the final
                  tax amount are recognized in income tax expense in the period
                  determined.

                  The Company uses the asset and liability method of accounting
                  for income taxes. Under the asset and liability method,
                  deferred tax assets and deferred liabilities are recognized
                  for the future tax consequences attributable to differences
                  between the financial statement carrying amounts of existing
                  assets and liabilities and their respective tax bases and
                  operating loss and tax credit carryforwards. Deferred tax
                  assets and deferred liabilities are measured using enacted tax
                  rates expected to apply to taxable income in the years in
                  which those temporary differences are expected to be recovered
                  or settled.

                  After the IPO on February 26, 1997, GST USA's ownership was
                  reduced to 63 percent. As a result, the entities no longer
                  meet the affiliated group test defined in Internal Revenue
                  Code Section 1504(a) and the Company will file stand-alone
                  returns for periods subsequent to February 26, 1997.

         (m)      Marketable Investment Securities

                  The Company classifies all of its marketable investment
                  securities as available-for-sale which are recorded at fair
                  market value. Unrealized holding gains and losses are excluded
                  from earnings and are reported, net of tax, as a separate
                  component of stockholders' equity until realized. A decline in
                  the market value of any available-for-sale security below cost
                  that is deemed other than temporary is charged to earnings
                  resulting in the establishment of a new cost basis for the
                  security. Dividend income is recognized when earned. Realized
                  gains and losses are included in earnings and are derived
                  using the specific-identification method for securities sold.

                          Notes to Financial Statements

         (n)      Earnings Per Common and Common Equivalent Share

                  Earnings per common and common equivalent share are computed
                  based on the weighted-average number of common shares and as
                  appropriate, dilutive common stock equivalents outstanding
                  during the period. Stock options are considered to be common
                  stock equivalents. The number of shares used to compute
                  primary earnings per common and common equivalent share were
                  7,350,623, 6,113,712, and 6,113,712, shares in 1997, 1996, and
                  1995, respectively. The number of shares used to compute
                  fully-diluted earnings per share reflect additional dilution
                  related to stock options and warrants using the market price
                  at the end of the period when higher than the average price
                  for the period. The number of shares used to compute
                  fully-diluted earnings per share were 7,602,156, 6,113,712,
                  and 6,113,712, shares in 1997, 1996, and 1995, respectively.

         (o)      Fair Value Disclosure

                  At September 30, 1997 and 1996, the book value of the
                  Company's financial instruments approximates fair value.

         (p)      Use of Estimates

                  Management of the Company has made a number of estimates and
                  assumptions relating to the reporting of assets and
                  liabilities and the disclosure of contingent assets and
                  liabilities at the date of the financial statements and the
                  reported amounts of revenues and expenses during the reporting
                  period. Actual results could differ from these estimates.

(4)      Notes Receivable (continued)

         The Company has sold carrier services to Overseas Telecom (iOverseasi)
         since 1994. Overseas is located in Brazil and provides international
         call back/reorigination services to companies and individuals primarily
         in Brazil and Eastern Europe. During the year ended September 30, 1996,
         Overseas became delinquent on certain of its payments. In fiscal 1997,
         the Company entered into a note receivable agreement with Overseas
         which provided for the repayment of the noncurrent outstanding amount
         (approximately $0.93 million) bearing interest at 12 percent. The note
         was secured primarily by Overseasi customer lists. In the fourth
         quarter of fiscal 1997, the Company exercised its call privileges under
         the note and took possession of the underlying collateral - the
         customer lists. There were two separate and distinct customer lists,
         one from Brazil and one from Eastern Europe. The customer list related
         to the Brazilian operations was sold to Intertoll Communications
         Network Corp. (iICN"), an existing customer of the Company with
         operations in Argentina and Brazil for $1,000,000 payable in 100
         monthly payments of $10,000. The related payments have been discounted
         at 20 percent with the unpaid amount of approximately $485,000
         classified as notes receivable in the accompanying balance sheet as of
         September 30, 1997.

         The customer list related to the Eastern European operations was
         recorded on the Companyis books at the lower of fair value or cost.
         Fair value was estimated by an independent third party appraiser using
         generally accepted valuation standards. Accordingly, a customer list of
         approximately $964,000 has been recorded as an intangible asset and
         will be amortized over a three-year period.

         On an ongoing basis, management reviews the valuation and amortization
         of intangible assets to determine possible impairment by comparing the
         carrying value of the asset to its undiscounted estimated future cash
         flows.

         Amortization expense relating to these assets was $1,085,468, $978,813,
         and $962,514 for 1997, 1996, and 1995, respectively. Of these amounts,
         $512,409, $405,755, and $442,734, for 1997, 1996, and 1995,
         respectively, was recorded as a component of cost of goods sold.

(7)      Stock Options

         In November 1996, the Company adopted the 1996 Stock Option Plan ("1996
         Plan") which was approved by the board of directors and GST USA. The
         Company has reserved 1,250,000 shares for issuance under the 1996 Plan,
         of which options to purchase 935,250 shares of common stock at an
         exercise price of $9.35 per share were granted. All options granted
         during the year expire on November 25, 2001. The Company may grant
         incentive stock options and nonqualified stock options to employees,
         officers, directors, independent contractors, and consultants. The
         exercise price of options must be greater than or equal to the
         estimated fair market value of the stock at the date of grant. The
         board of directors or the compensation committee thereof determines
         which eligible individuals are granted options, terms of the options,
         exercise price, number of shares subject to the option, vesting and
         exercisability. The 1996 Plan expires on November 25, 2006.

         The Company accounts for these plans under APB 25, under which no

         plans been determined consistent with SFAS 123, the Company's net

         Pro forma net earnings reflects only options granted in fiscal 1997.
         Therefore, the effect that calculating compensation cost for
         stock-based compensation under SFAS 123 has on the pro forma net
         earnings as shown above may not be representative of the effects on
         reported net earnings for future years.

         The fair value of each option grant is estimated on the date of the
         grant using the Black-Scholes option pricing model with the following
         weighted-average assumptions used for grants in fiscal 1997: risk-free
         interest rate of 6.0 percent; expected dividend yield of 0 percent;
         expected life of 3.4 years; and expected volatility of 82 percent.

(9)      Leases (continued)

         These leases generally require the Company to pay all executory costs
         such as maintenance and insurance. Rental expenses for all operating
         leases for 1997, 1996, and 1995, were $123,462, $100,299, and $116,944,
         respectively.


(10)     Profit Sharing Plans

         The Company sponsors a defined contribution 401(k) plan (the "Plan")
         for employees who have completed one year of service and attained the
         age of 21. Participants may defer up to 15 percent of eligible
         compensation. The Company, at its discretion, may match 50 percent of
         participant contributions up to 7.5 percent of participant
         compensation. Employer contributions made to the Plan were $88,361,
         $59,881, and $51,863, for the years ended September 30, 1997, 1996, and
         1995, respectively.

         Through September 30, 1996, the Company established a discretionary
         profit sharing program for full time employees who had completed one
         full year of employment. Under the plan, 10 percent of the increase in
         profits based on the Company's previous highest retained earnings
         balance were allocated among employees determined on length of
         employment and salary level at the discretion of the board of
         directors. Contributions to the program were $132,450 and $171,483 for
         the years ended September 30, 1996 and 1995, respectively. The program
         was terminated on September 30, 1996.

         also sells products and/or services to customers in the United Kingdom,

         Network carrier sales originating from countries outside the United
         States aggregated approximately $3,180,000 and $2,105,000 for the years
         ended September 30, 1997 and 1996, respectively. These sales are
         payable in U.S. dollars.


(12)     Commitments and Contingencies

         The Company acted as a guarantor for financing transactions executed
         under repurchase agreements with a financial institution for $3,482,182
         and $1,035,032 at September 30, 1997 and 1996, respectively. This
         results from the financial institution providing lease financing to the
         Company's customers to enable them to purchase product from the
         Company. At September 30, 1997, the Company had established a reserve
         of $200,000 for its estimated obligation under the recourse provisions
         and maintains a security interest in the equipment financed under the
         repurchase agreement. No such reserve was recorded as of September 30,
         1996. In addition to other covenants, the repurchase agreement requires
         the Company to maintain an unrestricted cash account of $6,000,000. The
         Company has also established a $750,000 revolving line of credit with
         this same financial institution. No balances were outstanding under
         this line of credit at September 30, 1997.

         On October 1, 1996, the Company entered into employment agreements with
         various employees which specify the individual's salary, benefits, and
         restrictions. All agreements expire on September 30, 2001.

(12)     Commitments and Contingencies (continued)

         On August 24, 1995, Aerotel, Ltd. and Aerotel U.S.A., Inc.,
         (collectively, "Aerotel") filed a patent infringement suit against the
         Company alleging that telephone systems manufactured and sold by the
         Company incorporating prepaid calling features infringe upon a patent
         which was issued to Aerotel in November 1987. The complaint further
         alleges defamation and unfair competition by the Company and seeks
         various damages. Aerotel seeks injunctive relief, damages of $18.7
         million for willful infringement of its patent and an order requiring
         the Company to publish a written apology to Aerotel. The Company has
         filed an Answer and Counterclaim denying patent infringement,
         defamation or unfair competition and seeking judgment that the Aerotel
         patent is invalid and that Aerotel has misused its patent in violation
         of antitrust laws. Based on information currently available, an
         estimate of potential loss cannot be made. However, management is of
         the opinion that there will be no material impact of the Company's
         financial position, results of operations or liquidity as a result of
         this suit. Accordingly, no provision for loss has been provided in the
         accompanying financial statements. An unfavorable decision could have a
         material adverse effect on the business, financial condition, and
         results of operations of the Company.

         In addition to the above, the Company has various legal claims and
         other contingent matters, incurred in the normal course of business.
         Although the final outcome of such matters cannot be predicted, the
         Company believes the ultimate disposition of these matters will not
         have a material adverse effect on the Company's financial condition,
         liquidity, or results of operations.

         As of September 30, 1997, the Company had capital expenditure purchase
         commitments outstanding of approximately $900,000.

(13)     Related Party Transactions

         In June 1997, and under contract with the Company, GST Realco, Inc.
         ("GST Realco"), a subsidiary of GST USA, completed construction of a
         40,000 square foot office building in Provo, Utah. The Company
         purchased the land and a portion of the building construction from GST
         Realco for $563,309 and $1,293,072, respectively, and currently
         occupies the property as its corporate and manufacturing facility.

         During the year ended September 30, 1996, GST USA borrowed $250,000
         from the Company on short-term notes bearing interest at 11 percent.
         The note was repaid by September 30, 1996. The Company recorded
         interest income of $2,602 relating to this note during the year ended
         September 30, 1996. There were no borrowings during fiscal 1997.

         Also, during the years ended September 30, 1997 and 1996, respectively,
         the Company sold $32,788 and $356,000 of application platform switching
         products and $ -0- and $2,571,731 of wholesale carrier usage to GST USA
         or subsidiaries and purchased $4,466,907 and $361,000 of wholesale
         carrier usage from GST USA.

         From April 1996 through May 1997 a member of the Company's board was
         compensated by GST USA for services rendered to GST USA and its
         subsidiaries.

                          Notes to Financial Statements

(13)     Related Party Transactions (continued)

         The Company has entered into a Deferred Compensation Trust Agreement
         (the Trust) with the chairman of the Company whereby the Company funded
         the trust in the amount of $144,000. The principal and related interest
         thereon are payable to the chairman based on a defined payment
         schedule. The Company, at its sole discretion, may at any time make
         additional contributions to the Trust. The Trust is subject to claims
         of the Company's creditors in the event of the Company's insolvency.


(14)     Accounting Standards Issued Not Yet Adopted

         In February 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 128, Earnings per Share
         (SFAS 128). SFAS 128 establishes a different method of computing
         earnings per share than is currently required under the provisions of
         Accounting Principles Board Opinion No. 15. Under SFAS 128, the Company
         will be required to present both basic earnings per share and diluted
         earnings per share. Basic and diluted earnings per share are expected
         to be comparable to the currently presented earnings per share. SFAS
         128 is effective for the consolidated financial statements for interim
         and annual periods ending after December 15, 1997. Accordingly, the
         Company plans to adopt SFAS 128 in the first quarter of its 1998 fiscal
         year and at that time all historical earnings per share data presented
         will be restated to conform with the provisions of SFAS 128.

         In 1997, the FASB also issued Statement No. 130, Reporting
         Comprehensive Income, and Statement No. 131, Disclosures About Segments
         of an Enterprise and Related Information. These statements which are
         effective for periods beginning after December 15, 1997, expand or
         modify disclosures and accordingly, will have no impact on the
         Company's reported financial position, results of operations or cash
         flows.

                          Notes to financial statements

1. Basis of Presentation

The interim financial statements included herein have been prepared by NACT
Telecommunications, Inc. without audit, pursuant to the rules and regulations of
the Securities and Exchange Commission (the "SEC"). Certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been condensed or
omitted pursuant to such SEC rules and regulations. These condensed financial
statements should be read in conjunction with the financial statements and notes
thereto included in the Company's September 30, 1997 audited financial
statements filed on form 10K with the SEC in December 1997. In the opinion of
management, the condensed financial statements included herein reflect all
adjustments necessary to present fairly the financial position of the Company as
of December 31, 1997 and September 30, 1997, and the results of its operations
and cash flows for the three month periods ended December 31, 1997 and 1996. The
results of operations for the interim periods are not necessarily indicative of
the results of operations for the full year.


2. Earnings Per Share

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, Earnings per Share (SFAS 128). SFAS 128
established a different method of computing earnings per share than these same
computations under the provisions of Accounting Principles Board Opinion No. 15.
Under SFAS 128, the Company is required to present both basic earnings per share
and diluted earnings per share. SFAS 128 is effective for both interim and
annual periods ending after December 15, 1997. Accordingly, the Company has
adopted SFAS 128 in the first quarter of fiscal 1998.

Basic earnings per share is computed based on the weighted average number of
common shares outstanding during the three month periods ended December 31, 1997
and 1996. Diluted earnings per share for the three month periods ended December
31, 1997 and 1996 is computed considering the dilutive effect of stock options,
and is not materially different from the basic earnings per share calculations.

3. Stock Plan

The Company's 1996 Stock Option Plan (the "Stock Option Plan") was approved by
the Board of Directors and sole stockholder of the Company on November 26, 1996.
The purpose of the Stock Option Plan is to create additional incentives for the
Company's employees, directors and others who perform substantial services to
the Company by providing an opportunity to purchase shares of the Common Stock
pursuant to the exercise of options granted under the Stock Option Plan. The
Company may grant options that qualify as incentive stock options under Section
422 of the Internal Revenue Code, and non-qualified stock options. Incentive
stock options may be granted to employees (including officers and directors who
are employees). Non-qualified stock options may be granted to employees,
officers, directors, independent contractors and consultants of the Company. As
of December 31, 1997, 1,250,000 shares were reserved for issuance under the
Stock Option Plan and options to purchase 1,039,065 shares of Common Stock were
outstanding.

Options become exercisable at such times and in such installments as the Board
of Directors or Compensation Committee provides. The Stock Option Plan will
terminate on November 25, 2006, unless earlier terminated by the Board of
Directors.

         (b) Pro Forma Financial Information. The Acquisition and Open Market
Purchase has been accounted for using the purchase method of accounting. In
connection with the Acquisition, World Access expects to record a charge of
approximately $43.5 million, representing the portion of the purchase price
allocated to in-process research and development. The following unaudited pro
forma consolidated balance sheet as of September 30, 1997 reflects the
Acquisition (together with the Open Market Purchase) as if it had been completed
on September 30, 1997. The following unaudited pro forma consolidated statement
of operations for the year ended December 31, 1996 and the nine months ended
September 30, 1997 reflect the Acquisition (together with the Open Market
Purchase) as if it had been completed as of January 1, 1996.

         The pro forma data does not purport to be indicative of the results
which would actually have been reported if the Acquisition (together with the
Open Market Purchase) had occurred on such dates or which may be reported in the
future. The pro forma data should be read in conjunction with the historical
consolidated financial statements of World Access, the historical consolidated

             NOTES TO UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET

(A) Represents the pro forma balance sheet for World Access, Inc. as presented
    in the Report on Form 10Q for the Three Months Ended September 30, 1997. The
    pro forma balance sheet presented above includes the effects of the sale of
    $115 million 4.5% convertible subordinated notes which was completed in
    October 1997.

(B) Represents the historical balance sheet of NACT Telecommunications, Inc. as
    of September 30, 1997.

(C) The Acquisition will be accounted for under the purchase method of
    accounting. In addition, in accordance with generally accepted accounting
    principles, the portion of the purchase price allocable to in-process
    research and development projects of NACT will be expensed at the
    consumation of the Acquisition. The amount of the one-time non-recurring
    charge is expected to be approximately $43.5 million. Since this charge is
    directly related to the Acquisition and will not recurr, the pro forma
    statements of operations have been prepared excluding this charge. The
    Company has not yet determined the final allocation of the purchase price,
    and accordingly, the amount shown below may differ from the amounts
    ultimately determined.

    The unallocated excess of purchase price over net assets acquired is
    determined as follows (in thousands):

         WHEREAS, World Access and NACT desire to make certain representations,
warranties, covenants and agreements in connection with the Mergers;

         SECTION 1.3. EFFECT OF THE MERGERS. At the Effective Time, the World
Access Merger and the NACT Merger shall have the effects set forth in the DGCL.

         SECTION 1.4. CHARTER AND BYLAWS. At the Effective Time: (i) with
respect to the World Access Merger, the certificate of incorporation and bylaws

World Access Surviving Corporation until further amended as provided therein and
in accordance with applicable Law; (ii) with respect to the NACT Merger, the
certificate of incorporation and bylaws of Sub-2, as in effect on the date

and in accordance with applicable Law.

         SECTION 1.5. DIRECTORS AND OFFICERS. From and after the Effective Time,
the directors and officers of each of World Access and NACT shall be the

                               CONVERSION OF STOCK

         SECTION 2.1. CONVERSION OF SUB-1 STOCK AND WORLD ACCESS STOCK. Subject
to the terms and conditions of this Agreement, as of the Effective Time and by
virtue of the World Access Merger and without any further action on the part of
the holder of any Sub-1 Stock or World Access Stock:

                  (a) all shares of World Access Stock which are held by World
Access as treasury stock shall be canceled and retired, and no consideration
shall be paid or delivered in exchange therefor;

                  (b) each share of World Access Stock outstanding immediately
prior to the Effective Time shall be canceled and converted solely into the
right to receive and be exchangeable for one share of common stock, $.01 par
value per share (the "Holdco Stock"), of Holdco (the "World Access
Consideration"); and



                                        3
<PAGE>   8



                  (c) each share of Sub-1 Stock issued and outstanding
immediately prior to the Effective Time shall be converted solely into one fully
paid and nonassessable share of common stock, par value $.01 per share, of the
World Access Surviving Corporation.

         SECTION 2.2. CONVERSION OF SUB-2 STOCK AND NACT STOCK. Subject to the
terms and conditions of this Agreement, as of the Effective Time and by virtue
of the NACT Merger and without any further action on the part of the holder of
any Sub-2 Stock or NACT Stock:

                  (a) all shares of NACT Stock which are held by NACT as
treasury stock shall be canceled and retired, and no consideration shall be paid
or delivered in exchange therefor;

                  (b) subject to Section 2.3 hereof, each share of NACT Stock
outstanding immediately prior to the Effective Time shall be canceled and
converted solely into the right to receive and become exchangeable for that
number of shares of Holdco Stock equal to the quotient of (x) $17.50 divided by
(y) the Closing Date Market Price (the "Exchange Ratio"); provided, however,
that (i) if the Closing Date Market Price is less than $20.88, then World Access
may terminate this Agreement by delivering notice of termination to NACT in the
manner contemplated by Section 10.2 hereof, and (ii) if the Closing Date Market
Price is more than $25.52, then the Exchange Ratio shall be equal to 0.6857 (the
number of shares of Holdco Stock into which each share of NACT Stock shall be
convertible pursuant to this Section 2.2(b) is hereinafter referred to as the
"NACT Consideration"); and

                  (c) each share of Sub-2 Stock issued and outstanding 
immediately prior to the Effective Time shall be converted solely into one fully
paid and nonassessable share of common stock, par value $.01 per share, of the
NACT Surviving Corporation.

         SECTION 2.3. FRACTIONAL SHARES. No scrip or fractional shares of Holdco
Stock shall be issued pursuant to the NACT Merger, and such fractional share
interests shall not entitle the owner thereof to vote or to any other rights of
a stockholder of Holdco. In lieu thereof, if any holder of NACT Stock would have
otherwise been entitled to a fractional share of Holdco Stock hereunder, then
such holder shall be entitled, after the later of the Effective Time or the
surrender of such holder's stock certificates that represent such shares of NACT
Stock to receive from Holdco cash (without interest) in an amount equal to the
product of such fractional part of a share of Holdco Stock multiplied by the
Closing Date Market Price.

         SECTION 2.4. EXCHANGE RATIO FOR WORLD ACCESS OPTIONS AND WORLD ACCESS
WARRANTS.

                  2.4.1. As of the Effective Time, each outstanding option
("World Access Option") and warrant ("World Access Warrant") to purchase World
Access Common Stock shall be assumed by Holdco and converted into an option or
warrant, as the case may be, to purchase shares of Holdco Common Stock, as
provided below. Following the Effective Time, each World Access Option shall
continue to have, and shall be subject to, the same terms and conditions set



                                        4

<PAGE>   9



forth in the applicable option plan or warrant plan (the "World Access Plans")
pursuant to which such World Access Option or World Access Warrant was granted,
except that each such World Access Option or World Access Warrant shall be
exercisable for the same number of shares of Holdco Common Stock as the number
of shares of World Access Common Stock for which such World Access Option or
World Access Warrant was exercisable immediately prior to the Effective Time.

                  2.4.2. As of the Effective Time, Holdco shall enter into an
assumption agreement with respect to each World Access Option and each World
Access Warrant, which shall provide for Holdco's assumption of the obligations
of World Access under the applicable World Access Plan. Prior to the Effective
Time, World Access shall make such amendments, if any, to the World Access Plans
as shall be necessary to permit such assumption in accordance with this Section
2.4.2.

                  2.4.3. It is the intention of the Parties that, to the extent
that any World Access Option constitutes an "incentive stock option" (within the
meaning of Section 422 of the Code) immediately prior to the Effective Time,
such World Access Option shall continue to qualify as an incentive stock option
to the maximum extent permitted by Section 422 of the Code, and that the
assumption of the World Access Option provided by this Section 2.4 shall satisfy
the conditions of Section 424(a)of the Code.

         SECTION 2.5. EXCHANGE RATIO FOR NACT OPTIONS.

                  2.5.1. As of the Effective Time, each option ("NACT Option")
to purchase NACT Common Stock then outstanding shall be assumed by Holdco and
converted into an option to purchase shares of Holdco Common Stock, as provided
below. Following the Effective Time, each NACT Option shall continue to have,
and shall be subject to, the same terms and conditions set forth in the
applicable option plan (the "NACT Plans") pursuant to which such NACT Option was
granted, except that (i) each such NACT Option shall be exercisable for that
number of shares of Holdco Stock equal to the product of (x) the number of
shares of NACT Stock for which such NACT Option was exercisable immediately
prior to the Effective Time and (y) the Exchange Ratio, rounded in the case of
any NACT Option other than any incentive stock option, up and, in the case of
any incentive stock option, down to the nearest whole share, if necessary, and
(ii) the exercise price per share of such NACT Option shall be equal to the
aggregate exercise price of such NACT Option immediately prior to the Effective
Time divided by the number of shares of Holdco Stock for which such NACT Option
shall be exercisable as determined in accordance with the preceding clause (i),
rounded up to the next highest cent, if necessary.

                  2.5.2. As of the Effective Time, Holdco shall enter into an
assumption agreement with respect to each NACT Option, which shall provide for
Holdco's assumption of the obligations of NACT under the applicable NACT Plan.
Prior to the Effective Time, NACT shall make such amendments, if any, to the
NACT Plans as shall be necessary to permit such assumption in accordance with
this Section 2.5.2.



                                        5
<PAGE>   10



                  2.5.3. It is the intention of the Parties that, to the extent
that any NACT Option constitutes an "incentive stock option" (within the meaning
of Section 422 of the Code) immediately prior to the Effective Time, such NACT
Option shall continue to qualify as an incentive stock option to the maximum
extent permitted by Section 422 of the Code, and that the assumption of the NACT
Option provided by this Section 2.5 shall satisfy the conditions of Section
424(a) of the Code.

                                   ARTICLE 3.
                       PAYMENT OF THE MERGER CONSIDERATION

         SECTION 3.1.    PAYMENT OF THE WORLD ACCESS CONSIDERATION AND THE 
NACT CONSIDERATION.

                  3.1.1. At or prior to the Effective Time, Holdco shall appoint
an agent reasonably satisfactory to World Access and NACT (the "Exchange Agent")
for the purpose of exchanging certificates representing outstanding shares of
World Access Stock and NACT Stock as provided herein. As of the Effective Time,
Holdco will deposit with the Exchange Agent, in trust for the benefit of holders
of shares of World Access Stock and NACT Stock, certificates representing the
shares of Holdco Stock issuable pursuant to Section 2.1 hereof. Holdco agrees to
make available to the Exchange Agent, from time to time as needed, cash
sufficient to pay cash in lieu of fractional shares pursuant to Section 2.3
hereof.

                  3.1.2. As promptly as practicable after the Effective Time,
the Exchange Agent shall send or cause to be sent to each former holder of
record of shares of World Access Stock and NACT Stock transmittal materials (the
"Letter of Transmittal") for use in exchanging their certificates formerly
representing World Access Stock and NACT Stock for the Merger Consideration
provided for in this Agreement. The Letter of Transmittal will contain
instructions with respect to the surrender of certificates representing World
Access Stock and NACT Stock and the receipt of the Merger Consideration
contemplated by this Agreement and will require each holder of World Access
Stock and NACT Stock to transfer good and marketable title to such World Access
Stock and NACT Stock to Holdco, free and clear of all Liens. Upon receipt of
properly completed Letters of Transmittal, the Exchange Agent shall pay the
appropriate Merger Consideration to the stockholders of World Access and NACT,
as appropriate. The Exchange Agent shall, as promptly as practicable after the
Effective Time, send or cause to be sent to each former holder of record of
World Access Stock and NACT Stock a Letter of Transmittal and, upon the proper
execution and return of such Letter of Transmittal to the Exchange Agent, the
appropriate Merger Consideration shall be promptly paid.

                  3.1.3. At the Effective Time, the stock transfer books of
World Access and NACT shall be closed as to holders of World Access Stock and
NACT Stock immediately prior to the Effective Time, and no transfer of World
Access Stock and NACT Stock by any such holder shall thereafter be made or
recognized and each outstanding certificate formerly representing World Access
Stock and NACT Stock shall, without any action on the part of any holder
thereof, no longer represent World Access Stock and NACT Stock. If, after the
Effective Time,



                                        6
<PAGE>   11



certificates are properly presented to the Exchange Agent, such certificates
shall be exchanged for the Merger Consideration contemplated by this Agreement
into which the World Access Stock and NACT Stock represented thereby were
converted in the Mergers.

         SECTION 3.2. LOST CERTIFICATES. In the event that any holder of World
Access Stock and NACT Stock is unable to deliver the certificate which
represents such holder's World Access Stock or NACT Stock, Holdco, in the
absence of actual notice that any World Access Stock or NACT Stock theretofore
represented by any such certificate has been acquired by a bona fide purchaser,
may, in its sole discretion, deliver to such holder the Merger Consideration
contemplated by this Agreement to which such holder is entitled in accordance
with the provisions of this Agreement upon the presentation of all of the
following:

                  (a) an affidavit or other evidence to the reasonable
satisfaction of Holdco that any such certificate has been lost, wrongfully taken
or destroyed;

other Parties, constitutes the legal, valid and binding obligations of Holdco

                               AFFILIATE AGREEMENT

WAXS Inc.
945 E. Paces Ferry Road, Suite 2240
Atlanta, Georgia 30326

Attention:  Chief Executive Officer

Gentlemen:

         The undersigned is a stockholder of _________________________
("Target"), a corporation organized under the laws of the State of Delaware, and
will become a stockholder of WAXS Inc. ("Holdco") pursuant to the transactions
described in the Agreement and Plan of Merger and Reorganization, dated as of
February ____, 1988 (the "Agreement"), by and among Target, Holdco and certain
affiliated parties. Under the terms of the Agreement, a subsidiary of Holdco
will be merged with and into Target (the "Merger"), with Target becoming a
wholly-owned subsidiary of Holdco, and the shares of the $.01 par value common
stock of Target ("Target Common Stock") will be converted into and exchanged for
shares of the $.01 par value common stock of Holdco ("Holdco Common Stock").
This Affiliate Agreement represents an agreement between the undersigned and
Holdco regarding certain rights and obligations of the undersigned in connection
with the shares of Holdco Common Stock to be received by the undersigned as a
result of the Merger.

         In consideration of the Merger and the mutual covenants contained
herein, the undersigned and Holdco hereby agree as follows:

         1.    AFFILIATE STATUS. The undersigned understands and agrees that as 
to Target the undersigned is an "affiliate" under Rule 145(c) as defined in Rule
405 of the Rules and Regulations of the Securities and Exchange Commission
("SEC") promulgated under the Securities Act of 1933, as amended ("1933 Act"),
and the undersigned anticipates that the undersigned will be such an "affiliate"
at the time of the Merger.

         2.    COVENANTS AND WARRANTIES OF UNDERSIGNED. The undersigned 
represents, warrants and agrees that:

               (a)  The Holdco Common Stock received by the undersigned as a
result of the Merger will be taken for the undersigned's own account and not for
others, directly or indirectly, in whole or in part.

               (b)  Holdco has informed the undersigned that any distribution
by the undersigned of Holdco Common Stock has not been registered under the 1933
Act and that shares


<PAGE>   34



of Holdco Common Stock received pursuant to the Merger can only be sold by the
undersigned (i) following registration under the 1933 Act, or (ii) in conformity
with the volume and other requirements of Rule 145(d) promulgated by the SEC as
the same now exist or may hereafter be amended, or (iii) to the extent some
other exemption from registration under the 1933 Act might be available. The
undersigned understands that Holdco is under no obligation to file a
registration statement with the SEC covering the disposition of the
undersigned's shares of Holdco Common Stock.

         3.    RESTRICTIONS ON TRANSFER.

               (a)  The undersigned understands and agrees that stop transfer
instructions with respect to the shares of Holdco Common Stock received by the
undersigned pursuant to the Merger will be given to Holdco's Transfer Agent and
that there will be placed on the certificates for such shares, or shares issued
in substitution thereof, a legend stating in substance:

         "The shares represented by this certificate may not be sold,
         transferred or otherwise disposed of except or unless (i) 
         covered by an effective registration statement under the 
         Securities Act of 1933, as amended, (ii) in accordance with 
         (x) Rule 145(d) (in the case of shares issued to an individual 
         who is not an affiliate of the issuer) or (y) Rule 144 (in the 
         case of shares issued to an individual who is an affiliate of 
         the issuer) of the Rules and Regulations of such Act, or (iii) 
         in accordance with a legal opinion satisfactory to counsel for
         the issuer that such sale or transfer is otherwise exempt from 
         the registration requirements of such Act."

               (b) Such legend will also be placed on any certificate
representing Holdco securities issued subsequent to the original issuance of the
Holdco Common Stock pursuant to the Merger as a result of any stock dividend,
stock split, or other recapitalization as long as the Holdco Common Stock issued
to the undersigned pursuant to the Merger has not been transferred in such
manner to justify the removal of the legend therefrom. If the provisions of
Rules 144 and 145 are amended to eliminate restrictions applicable to the Holdco
Common Stock received by the undersigned pursuant to the Merger, or at the
expiration of the restrictive period set forth in Rule 145(d), Holdco, upon the
request of the undersigned, will cause the certificates representing the shares
of Holdco Common Stock issued to the undersigned in connection with the Merger
to be reissued free of any legend relating to the restrictions set forth in
Rules 144 and 145(d) upon receipt by Holdco of an opinion of its counsel to the
effect that such legend may be removed.

         4.    UNDERSTANDING OF RESTRICTIONS ON DISPOSITIONS. The undersigned 
has carefully read the Agreement and this Affiliate Agreement and discussed
their requirements and impact upon the undersigned's ability to sell, transfer,
or otherwise dispose of the shares of Holdco Common Stock received by the
undersigned in connection with the Merger, to the extent the undersigned
believes necessary, with counsel for the undersigned or for Target.



                                        2
<PAGE>   35



         5.    FILING OF REPORTS BY HOLDCO. Holdco agrees, for a period of two
years after the effective date of the Merger, to file on a timely basis all
reports required to be filed by it pursuant to Section 13 of the Securities
Exchange Act of 1934, as amended (the "1934 Act"), so that the public
information provisions of Rule 145(d) promulgated by the SEC, as the same are
presently in effect, will be available to the undersigned in the event the
undersigned desires to transfer any shares of Holdco Common Stock issued to the
undersigned pursuant to the Merger.

         6.    TRANSFER UNDER RULE 145(D). If the undersigned desires to sell 
or otherwise transfer the shares of Holdco Common Stock received by the
undersigned in connection with the Merger at any time during the restrictive
period set forth in Rule 145(d), the undersigned will provide the necessary
representation letter to the Transfer Agent for Holdco Common Stock, together
with such additional information as the Transfer Agent may reasonably request.
If Holdco's counsel concludes that such proposed sale or transfer complies with
the requirements of Rule 145(d), Holdco shall cause such counsel, at Holdco's
expense, to provide such opinions as may be necessary to Holdco's Transfer Agent
so that the undersigned may complete the proposed sale or transfer.

         7.    ACKNOWLEDGMENTS. The undersigned recognizes and agrees that the
foregoing provisions also apply with respect to Target Common Stock held by, and
Holdco Common Stock issued in connection with the Merger to, (a) the
undersigned's spouse, (b) any relative of the undersigned or of the
undersigned's spouse who has the same home as the undersigned, (c) any trust or
estate in which the undersigned, the undersigned's spouse, and any such relative
collectively own at least a 10% beneficial interest or of which any of the
foregoing serves as trustee, executor or in any similar capacity, and (d) any
corporation or other organization in which the undersigned, the undersigned's
spouse and any such relative collectively own at least 10% of any class of
equity securities or of the equity interest. The undersigned further recognizes
that, in the event that the undersigned is a director or executive officer of
Holdco or becomes a director or executive officer of Holdco upon consummation of
the Merger, then, among other things, any sale of Holdco Common Stock by the
undersigned within a period of less than six months following the effective time
of the Merger may subject the undersigned to liability pursuant to Section 16(b)
of the 1934 Act.

         8.    MISCELLANEOUS. This Affiliate Agreement is the complete 
agreement between Holdco and the undersigned concerning the subject matter
hereof. Any notice required to be sent to any party hereunder shall be sent by
registered or certified mail, return receipt requested, using the addresses set
forth herein or such other address as shall be furnished in writing by the
parties. This Affiliate Agreement shall be governed by the laws of the State of
Delaware.

FOR IMMEDIATE RELEASE

ATLANTA, GEORGIA - February 25, 1998 - WORLD ACCESS, INC. (NASDAQ: WAXS)
announced today that it has signed a definitive merger agreement with NACT
Telecommunications, Inc. (NASDAQ: NACT) to acquire approximately 2.7 million
shares of NACT common stock currently held by public stockholders. Pursuant to
the terms of the merger agreement, World Access will pay $17.50 per share of
NACT common stock, or approximately $46.6 million, through the issuance of new
shares of World Access common stock.

The merger agreement provides that each share of NACT common stock will be
converted into shares of World Access common stock having a value of $17.50 per
share based on the average of the daily closing price of World Access common
stock as reported on the Nasdaq National Market System on each of the 20
consecutive trading days ending with the 3rd day immediately preceding the
effective time of the merger (the "Closing Price"). If the Closing Price is more
than $25.52, then each share of NACT common stock will be converted into 0.6857
shares of World Access common stock. If the Closing Price is less than $20.88
per share, then World Access may terminate the merger agreement.

The merger agreement was negotiated on behalf of NACT by a Special Committee of
the NACT Board and has been approved by the Boards of Directors of NACT and
World Access. In addition, NACT has received a fairness opinion with respect to
the merger from NationsBanc Montgomery Securities LLC. The merger is subject to,
among other things, the consummation of the GST Stock Purchase, approval of the
NACT stockholders, and the satisfaction of other customary conditions.

World Access previously announced that it had entered into a definitive
agreement with GST Telecommunications, Inc. ("GST") and GST USA, Inc., a wholly
owned subsidiary of GST ("GST USA"), to acquire shares of NACT common stock held
by GST USA for $17.50 per share, or approximately $89.5 million (the "GST Stock
Purchase"). Upon completion of the GST Stock Purchase, which is currently
scheduled for early March, and the above merger transaction, World Access will
own 100% of NACT. The total consideration paid to acquire NACT will be
approximately $141 million.

Steven A. Odom, Chairman and Chief Executive Officer, said "The acquisition of
NACT, which is expected to be accretive to World Access' 1998 earnings, is in
line with the Company's strategy to broaden its offering of switching, transport
and access products and fully support its customers as they build new and/or
upgrade existing telecommunications networks. NACT has been providing its
customers comprehensive telecommunications network equipment and services since
1982. It has enjoyed considerable growth and success in recent years since the
introduction of its STX tandem switch in February 1996. The STX switch, when
combined with NACT's multi-tasking billing systems, provide a turnkey package
for the emerging interexchange carrier industry. We believe that the STX switch
represents today's benchmark for the fast growing, specialty application
switching systems industry."

"We are particularly pleased that Lindsay Wallace, President and Chief Executive
Officer of NACT, will continue to manage NACT as a majority owned subsidiary of
World Access. Under the leadership of Mr. Wallace, and his outstanding team of
engineering, sales and operations professionals, NACT reported record revenues
of $27.7 million and pre-tax income of $6.3 million in its most recently
completed fiscal year. We are optimistic that World Access' financial strength,
extensive customer base, engineering capabilities and broad range of
manufacturing and support services will further support NACT's existing business
and provide additional sales and profit growth opportunities for both
companies."

World Access, Inc. develops, manufactures and markets wireline and wireless
switching, transport and access products primarily for the United States,
Caribbean Basin and Latin American telecommunications markets. The Company
offers digital switches, cellular base stations, fixed wireless local loop
systems, intelligent multiplexers, digital loop carriers, microwave and
millimeterwave radio equipment and other wireless communications products. To
support and complement its product sales, the Company also provides its
customers with a broad range of design, engineering, manufacturing, testing,
installation, repair and other value-added services.
