ITEM 5.  OTHER EVENTS
 
     As previously reported, on June 4, 1998, World Access, Inc. ("World
Access") announced that it had entered into a definitive Agreement and Plan of
Merger and Reorganization (the "Merger Agreement") with WAXS INC., a
wholly-owned subsidiary of World Access ("New World Access"), Tail Acquisition
Corporation, a wholly-owned subsidiary of New World Access ("Merger Sub"), and
Telco Systems, Inc. ("Telco") pursuant to which, among other things, Merger Sub
will merge with and into Telco and Telco shall thereupon become a wholly-owned
subsidiary of New World Access (the "Merger").
 
     As a result of the Merger, each outstanding share of Telco common stock,
$.01 par value per share ("Telco Common Stock"), shall be converted into the
right to receive that number of shares of (i) World Access common stock, $.01
par value per share ("World Access Common Stock"), or (ii) if the previously
announced holding company reorganization shall have been consummated on or
before the time of the Merger, New World Access common stock, $.01 par value per
share ("New World Access Common Stock") (in either case, the "Merger Common
Stock"), equal to the quotient of $17.00 divided by the average daily closing
price of World Access Common Stock as reported on Nasdaq on each of the twenty
consecutive trading days ending on the second business day prior to the date of
the Merger (the "Average Closing Price"), provided that if the Average Closing
Price is more than $36.00 per share, then each share of Telco Common Stock will
be converted into .4722 shares of Merger Common Stock and if the Average Closing
Price is less than $29.00 per share, then each share of Telco Common Stock will
be converted into .5862 shares of Merger Common Stock.
 
     The Merger is intended to constitute a tax-free reorganization under
Section 368(a) of the Internal Revenue Code of 1986, as amended, and will be
accounted for as a purchase. The consummation of the Merger is subject to (i)
clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, (ii) the approval by the respective stockholders of World Access (or
New World Access, as the case may be) and Telco, (iii) the approval by the
stockholders of World Access (or New World Access, as the case may be) of an
increase in the authorized shares of common stock of such corporation, and (iv)
the satisfaction or waiver of customary conditions.
 
     In connection with the Merger Agreement, Kopp Investment Advisors, Inc. and
the directors and certain executive officers of Telco entered into a
Stockholders Proxy Agreement with New World Access pursuant to which, among
other things, they agreed to vote an aggregate of approximately 8.0% of the
outstanding shares of Telco Common Stock in favor of the Merger.
 
     The foregoing description of the Merger, the Merger Agreement and the
Stockholders Proxy Agreement is qualified in its entirety by reference to the
Merger Agreement and the Stockholders Proxy Agreement, which have been filed as
exhibits to World Access' Form 8-K filed with the Securities and Exchange
Commission on June 8, 1998.
 
ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS
 
     (a) Financial Statements of Business Acquired.  Included in this report are
the following financial statements:
 
          (i) The unaudited consolidated financial statements of Telco for the
     three months and nine months in each of the periods ended May 31, 1998 and
     1997; and
 
          (ii) The audited consolidated financial statements of Telco for the
     year ended August 31, 1997, which have been audited by the independent
     accounting firm of Ernst & Young LLP, whose opinion thereon is included
     herein.
 
     (b) Pro Forma Financial Information.  The Unaudited Pro Forma Combined
Financial Statements of New World Access give effect to the consummation of the
several transactions that World Access has completed or that are currently
contemplated. The Unaudited Pro Forma Combined Statements of Operations give
effect to: (1) the acquisition of Advanced TechCom, Inc. ("ATI"), which was
consummated on January 29, 1998; (2) the acquisition of a 67.3% majority
interest in NACT Telecommunications, Inc.
 
                                        1
<PAGE>   3
 
("NACT") (the "NACT Stock Purchase"), which was consummated on February 27,
1998; (3) the acquisition of the remainder of NACT (the "NACT Merger"); (4) the
acquisition of Cherry Communications Incorporated (d/b/a Resurgens
Communications Group) and Cherry Communications U.K. Limited (collectively the
"Resurgens Transaction"); and (5) the Merger as if each of these acquisitions
had occurred on January 1, 1997. The Unaudited Pro Forma Combined Balance Sheet
gives effect to: the NACT Merger, the Resurgens Transaction and the Merger as if
they had been completed on June 30, 1998.
 
     As Telco's fiscal year end, August 31, differs from World Access' fiscal
year-end by more than 93 days, Telco's results of operations for the period from
November 25, 1996 through November 30, 1997 were used in preparing the Unaudited
Pro Forma Combined Statement of Operations for the year ended December 31, 1997.
Telco's results of operations for the six months from December 1, 1997 through
May 31, 1998 were used in preparing the Unaudited Pro Forma Combined Statement
of Operations for the six months ended June 30, 1998. Telco's May 31, 1998
balance sheet was utilized in preparing the Unaudited Pro Forma Combined Balance
Sheet as of June 30, 1998.
 
     The pro forma adjustments are based upon currently available information
and upon certain assumptions that the management of World Access believes are
reasonable. Each of the acquisition transactions above has been accounted for
using the purchase method of accounting. The adjustments recorded in the
Unaudited Pro Forma Combined Financial Statements represent the preliminary
determination of these adjustments based upon available information. There can
be no assurance that the actual adjustments will not differ significantly from
the pro forma adjustments reflected in the Unaudited Pro Forma Combined
Financial Statements.
 
     In connection with the consummation of the pending acquisition
transactions, World Access expects to record charges representing the estimated
portion of the purchase price allocated to in-process research and development
of $73.9 million for the Merger. In addition, in the six month period ended June
30, 1998, World Access recorded charges representing the estimated portion of
the purchase price allocated to in-process research and development of $44.6
million and $5.4 million for the NACT Stock Purchase and ATI acquisition,
respectively, and World Access has assumed, for purposes of these pro forma
combined financial statements, that in the three months ended September 30,
1998, it will record $21.9 million in charges representing the estimated
purchase price allocated to in-process research and development in connection
with the NACT Merger. Since these charges are directly related to the
acquisitions and will not recur, the Unaudited Pro Forma Combined Statements of
Operations have been prepared excluding these one-time non-recurring charges.
 
     The Unaudited Pro Forma Combined Financial Statements are not necessarily
indicative of the financial position or the future results of operations or
results that might have been achieved if the foregoing acquisition transactions
had been consummated as of the indicated dates. The Unaudited Pro Forma Combined
Financial Statements should be read in conjunction with the historical
consolidated financial statements of World Access, ATI, NACT, and Telco, the
historical combined financial statements of Resurgens and the related notes
thereto.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Shareholders of Telco Systems, Inc.
 
     We have audited the accompanying consolidated balance sheets of Telco
Systems, Inc. as of August 31, 1997 and August 25, 1996, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended August 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Telco Systems, Inc. at August 31, 1997, and August 25, 1996, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended August 31, 1997, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1  SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The financial statements consolidate the accounts of Telco Systems, Inc.,
and its subsidiaries (the Company). Intercompany accounts and transactions have
been eliminated. The Company's fiscal year ends on the last Sunday in August
which included 53 weeks in fiscal 1997 and 52 weeks in both fiscal 1996 and
fiscal 1995. Certain amounts reported in prior years have been reclassified to
be consistent with the current year's presentation.
 
     The Company has 50% limited partnership interests in two real estate
partnerships which are accounted for by the equity method of accounting. The
aggregate net investment in these partnerships on the accompanying balance
sheets is not material (See Note 7).
 
  New Accounting Standards
 
     In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards 128 (SFAS 128), "Earnings Per Share"
which will require adoption in the Company's second quarter of fiscal 1998. This
statement specifies the computation, presentation and disclosure requirements of
earnings per share. The Company believes that adoption of this statement will
have no material impact on its consolidated financial statements and related
disclosures.
 
     In June 1997, the FASB issued Statement No. 130, "Reporting Comprehensive
Income" (SFAS 130). SFAS 130 establishes standards for reporting comprehensive
income and its components in a full set of general purpose financial statements.
SFAS 130 requires that items to be recorded in comprehensive income, which
include unrealized gains/losses on marketable securities classified as
available-for-sale and cumulative translation adjustments, be displayed with the
same prominence as other financial statement items. The Company is in the
process of determining the effect of adoption of this statement on its
consolidated financial statements and related disclosures. SFAS 130 is required
to be adopted in the Company's financial statements for the year ending August
29, 1999.
 
     In June 1997, the FASB issued Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information," (SFAS 131). SFAS 131
establishes standards for the way public business enterprises report information
about operating segments in annual financial statements and requires those
enterprises to report selected information about operating segments in interim
financial reports issued to shareholders. SFAS 131 also establishes standards
for related disclosures about products and services, geographic areas, and major
customers. SFAS 131 is required to be adopted in the Company's financial
statements for the year ending August 29, 1999. The adoption of SFAS 131 will
have no impact on the Company's financial results or financial condition, but
may result in certain disclosures of segment information.
 
  Use of Estimates in the Preparation of Financial Statements
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
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 those estimates.
 
  Revenue Recognition
 
     In general, the Company recognizes revenue from product sales at the time
of shipment. In certain contractual situations, revenue is recognized when the
product is accepted by the customer.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Product Warranty
 
     Expected future product warranty liability is provided for when the product
is sold.
 
  Cash Equivalents and Marketable Securities
 
     The Company classifies all of its marketable securities as
available-for-sale securities. These securities are stated at their fair value.
There are currently no unrealized holding gains and losses. The Company
considers all highly liquid investments with maturity of 91 days or less to be
cash equivalents. Those instruments with maturities greater than 91 are
classified as marketable securities. Cash equivalents and marketable securities
are carried at market, and consist of U.S. Government securities, bank
certificates of deposit and corporate issues. All securities mature within
twelve months.
 
  Inventories
 
     Inventories are stated at the lower of cost or market. The cost of products
sold is based on standard costs, which approximate actual costs as determined by
the first-in, first-out method.
 
     Inventories at fiscal year end were as follows:

  Plant and Equipment
 
     Additions to plant and equipment are recorded at cost. Depreciation is
determined by using the straight-line method over the estimated useful lives of
the assets -- three to eight years. Leasehold improvements are amortized on a
straight-line basis over the shorter of their estimated useful life or the lease
term.
 
     Plant and equipment, at cost, at fiscal year end were as follows:

  Intangible and Other Assets
 
     Intangible assets arising in connection with business acquisitions were
$7,122,000 and $7,791,000 at August 31, 1997 and August 25, 1996, respectively.
They are amortized over lives ranging from seven to twenty-five years using the
straight-line method, with an average remaining life of 10.7 years. The carrying
value of goodwill is reviewed periodically based on the undiscounted cash flows
of the entities acquired over the remaining amortization period. Should this
review indicate that goodwill will not be recoverable, the carrying value will
be reduced by the estimated shortfall of undiscounted cash flows.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Concentrations of Credit Risk
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of cash equivalents, short-term
investments, and accounts receivable. The Company's temporary cash investments,
which are principally limited to U.S. Government securities and bank
certificates of deposit, are subject to minimal risk. The Company routinely
assesses the financial strength of its customers and, as a consequence, believes
that its trade accounts receivable credit risk exposure is limited.
 
  Earnings (loss) Per Share
 
     Earnings (loss) per share is based on the weighted average number of common
shares outstanding and common stock equivalents, if dilutive. Fully diluted
earnings per share did not differ significantly from primary earnings per share
in any year. Net loss per share in fiscal years 1997 and 1996 did not consider
common stock equivalents as the effect would be antidilutive.
 
NOTE 2  DESCRIPTION OF BUSINESS
 
     The Company is engaged in a single business segment constituting the
development, manufacturing, and marketing of broadband transmission products,
network access products, and bandwidth optimization products for the
telecommunications industry. Regional Bell Operating Companies (RBOC),
independent telephone companies, and interexchange carriers are the primary

     SFAS 109, "Accounting for Income Taxes", requires that a valuation reserve
be established if it is "more likely than not" that realization of the tax
benefits will not occur. The valuation reserve increased by $1,946,000 in fiscal
1997. This change is due primarily to an increase in the current year of
inventory and other reserves. These items have been fully reserved.
 
     At August 31, 1997, the Company had net operating loss carryforwards to
reduce future taxable income of $5,000,000. To the extent not utilized, the U.S.

NOTE 7  LEASE COMMITMENTS
 
     The Company leases a 216,000 square-foot manufacturing, research and

increase with an increase in the property value) out of the proceeds of any sale
or future refinancing of the property. The gross rent payable is $1.5 million

January 31, 2004, gross rent payable is $1.7 million annually.
 
     In June 1997, the Company entered into a sale-leaseback arrangement for
certain computer and other electronic equipment which provided cash of
approximately $2.6 million. The operating leases contained in the arrangement
cover periods from two to four years. All of equipment included in the
transaction was purchased by the Company within the last eighteen months.
 
     The Company leases other facilities and certain equipment under
noncancelable operating leases expiring at various dates through 2005. The
Company is required to pay property taxes, insurance and normal maintenance
costs. Certain of the lease agreements provide for five-year renewal options,
and future lease payments could increase based on the Consumer Price Index.
 
     Minimum annual lease commitments under non-cancelable operating leases for
facilities and equipment as of August 31, 1997 are set forth in the following
table. Amounts relating to excess facilities included herein have been accrued

     The plan included the consolidation and move of manufacturing operations
from the Company's Fremont, California facility to its facility located in
Norwood, Massachusetts. During fiscal 1997, the plan was accomplished within
original cost estimates. At August 31, 1997, the remaining reserve balance of
$1,657,000 was specifically designated for excess facility costs at the Fremont,
California location.
 
     At August 31, 1997, the remaining fiscal 1993 restructuring reserve for

NOTE 9  STOCK PLANS
 
     Under the Company's 1980 Stock Option Plan, the 1988 Non-Qualified Stock
Option Plan, and the 1990 Stock Option Plan (the Plans), officers, directors,
and key employees have been granted options to purchase shares of the Company's
common stock at a price equal to the market value at the date of grant. Options
normally become exercisable ratably over a 48 month period, commencing six
months from the date of grant, and expire after ten years. At August 31, 1997,
1,479,786 shares of common stock were reserved for issuance under the Plans.
 
     On May 20, 1997, the Board of Directors approved an amendment to the
Company's 1990 Stock Option Plan and reduced the exercise price of certain stock
options granted to employees between May 15, 1996 and May 13, 1997 at exercise
prices ranging from $11.50 to $20.875 per share. The exercise price was adjusted
to be equal to the current market price on that day. Stock options granted to
the Company's Board of Directors and to employees in conjunction with a general
option grant on March 5, 1997 were excluded from this action. Approximately
388,581 shares were reduced to the new exercise price of $9.625.
 
     On February 15, 1996, 92,000 restricted shares of the Company's common
stock were granted and issued to certain key employees. Shares were awarded in
the name of each of the participants who have all the rights of other
stockholders, subject to certain restrictions and forfeiture provisions. At
August 31, 1997, 7,500 shares carried restrictions. Restrictions on the shares
expire ratably on the anniversary date of the award over the next three years.

     At August 31, 1997, August 25, 1996, and August 27, 1995, there were
464,589 shares, 464,767 shares, and 413,495 shares exercisable, respectively.
 
     Under the Company's 1983 Employee Stock Purchase Plan, eligible employees
may purchase shares of common stock through payroll deductions (up to a maximum
of 10% of their salary) at a price equal to 85% of the lower of the stock's fair
market value at the beginning or at the end of each six month offering period.
There were 38,947 shares issuable under the Plan for fiscal 1997 of which 22,112
were outstanding at August 31, 1997. For fiscal 1996 and 1995, 56,010 shares and
56,005 shares, respectively, were issued under the Plan. At August 31, 1997,
59,383 shares of common stock were reserved for issuance under the Plan.
 
     In October 1995, the Financial Accounting Standards Board issues Statement
of Financial Accounting Standard 123 (SFAS 123), "Accounting for Stock-Based
Compensation". SFAS 123 requires that companies either recognize compensation
expense for grants of stock, stock options and other equity instruments based on
fair value, or provide pro forma disclosure of net income and earnings per share
in the notes to the financial statements. The Company adopted the
disclosure-only provisions of SFAS 123 in fiscal 1997 and has applied APB
Opinion No. 25 and related interpretations in accounting for its plans.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 10  EMPLOYEE BENEFIT PLAN
 
     The Company maintains a defined contribution savings plan under the
provisions of Internal Revenue Code Section 401(k). Under the terms of the Plan,
the Company contributes up to 3% of base pay to a fund which is held by a
trustee. All employees are eligible to participate in the Plan and are entitled,
upon termination or retirement, to receive their vested portion of the savings
fund assets. The unvested portion remains in the Plan and is used to reduce
future Plan expense. Total Plan expense was $468,000 in fiscal 1997, $547,000 in
fiscal 1996, and $525,000 in fiscal 1995.
 
NOTE 11  STOCKHOLDER RIGHTS PLAN
 
     On February 19, 1997, the Board of Directors of Telco Systems, Inc. adopted
a Stockholder Rights Plan (the "Plan") and distributed one Right for each
outstanding share of the Company's Common Stock, par value $.01 per share. The
Rights were issued to holders of record of Common Stock outstanding on February
19, 1997. Each share of Common Stock issued after February 19, 1997 will also
include one Right subject to certain limitations. Each Right when it becomes
exercisable will initially entitle the registered holder to purchase from the
Company one one-hundredth (1/100th) of a share of Series A Participating
Cumulative Preferred Stock, par value $.01 per share ("Series A Preferred
Stock"), of the Company at a price of $50.00 (the "Exercise Price").
 
     Currently, the Rights are attached to the Company's common stock. These
Rights are not now exercisable and cannot be transferred separately. The Rights
become exercisable and separately transferable when the Board learns that any
person or group (other than Kopp Investment Advisors, Inc. and its affiliates or
associates (collectively "KIA")), has acquired 15% or more of the Company's
outstanding common stock or on such date as may be designated by the Board
following the announcement of a tender or exchange offer for outstanding shares
of common stock which could result in the offeror becoming the beneficial owner
of 15% or more of the Company's outstanding common stock. Under such
circumstances, holders of the Rights will be entitled to purchase, for the
Exercise Price, that number of hundredths of a share of Series A Preferred Stock
equivalent to the number of shares of the Company's common stock (or under
certain circumstances other equity securities) having a market value of two
times the Exercise Price. 15% holders (other than KIA), however, are not
entitled to exercise their Rights under such circumstances. As a result, their
voting and equity interests in the Company would be substantially diluted should
the rights ever be exercised.
 
     The Rights expire in February 2007, but may be redeemed earlier by the
Company in accordance with the provisions of the Rights Plan at a price of $.01
per Right.

NOTE 1 -- BASIS OF PRESENTATION
 
     The consolidated financial statements of Telco Systems, Inc. (the
"Company") included in this report reflect all adjustments (consisting of only
normally recurring accruals) which, in the opinion of management, are necessary
for a fair presentation of the consolidated financial position at May 31, 1998
and the consolidated statements of operations and cash flows for the nine months
ended May 31, 1998 and May 25, 1997. The unaudited results of operations for the
interim periods reported are not necessarily indicative of results to be
expected for the year.
 
     Certain notes and other information have been condensed or omitted from
these interim financial statements. The statements, therefore, should be read in
conjunction with the consolidated financial statements and related notes
included in the Telco Systems, Inc. Annual Report on Form 10-K for the year
ended August 31, 1997.

NOTE 4 -- ACQUISITION
 
     On January 26, 1998, the Company acquired substantially all of the assets
of Jupiter Technology, Inc., a privately held company engaged in the development
of ATM and frame relay access equipment. The transaction was accounted for using
the purchase method at a cost of $6.2 million, including issuance of 101,636
shares of common stock. The purchase price included $5.1 million which
represented the value of in-process technology that had not yet reached
technological feasibility and had no alternative use. This amount was expensed
during the third quarter of fiscal 1998. In addition, the purchase price
included $1.1 million of goodwill, which will be amortized over five years.

NOTE 5 -- (LOSS) EARNINGS PER SHARE
 
     In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings per Share", which the Company adopted in the second quarter
of fiscal 1998. The Company has restated all prior period per share amounts to
comply with the requirements of FAS 128. Under the new requirements, primary and
fully diluted earnings per share were replaced by basic and diluted earnings per
share. Basic earnings per common share is calculated by dividing net income or
loss by the weighted average number of common shares outstanding during the
periods. Diluted earnings per share is calculated by dividing net income or loss
by the sum of the weighted average number of common shares outstanding plus all
additional common shares that would have been outstanding if potentially
dilutive common shares had been issued. Potentially dilutive common shares were
excluded from the diluted calculation for those periods in which the Company
reported a net loss. The following table reconciles the number of shares
utilized in the earnings per share calculations for the periods ended May 31,
1998 and May 25, 1997.

NOTE 6 -- SUBSEQUENT EVENT
 
     On June 4, 1998, the Company entered into a definitive agreement to merge
with World Access, Inc. The transaction will be subject to stockholder and
regulatory approval and is expected to be accounted for as a purchase. The
merger agreement provides that all shares of the Company's common stock will be
converted into shares of World Access common stock having a value of $17.00 per
share, based on the average daily closing price of World Access common stock as
reported on the Nasdaq National Market System for a predefined period prior to
the effective time of the merger (the "Closing Price"). If the Closing Price is
more than $36.00, then each share of the Company's common stock will be
converted into 0.4722 shares of World Access common stock. If the Closing Price
is less than $29.00, then each share of the Company's common stock will be
converted into 0.5862 shares of World Access common stock.

GENERAL HISTORICAL INFORMATION:
 
ACQUISITIONS OF ATI AND NACT
 
     The ATI acquisition consummated on January 29, 1998 and the NACT Stock
Purchase consummated on February 27, 1998 have been accounted for under the
purchase method of accounting. The historical consolidated financial statements
of World Access include the results of the operations of ATI and NACT from
February 1, 1998 and March 1, 1998, respectively. The purchase price of ATI and
the majority interest in NACT was allocated to the fair values of the net assets
acquired, to in-process research and development projects and to goodwill.
During the first quarter of 1998, $5.4 million and $44.6 million of purchased
in-process research and development technologies related to the ATI acquisition
and the NACT Stock Purchase, respectively, was expensed in accordance with the
applicable accounting rules. See Note 2 to Consolidated Financial Statements in
the World Access June 30 Form 10-Q for further descriptions of these
acquisitions.
 
AEROTEL LITIGATION
 
     On August 24, 1996, Aerotel, Ltd. and Aerotel U.S.A., Inc. (collectively,
"Aerotel") commenced an action against NACT and a customer of NACT alleging that
telephone systems manufactured and sold by NACT incorporating prepaid debit card
features infringe upon Aerotel's patent which was issued in November 1987. See
Note 8 to Consolidated Financial Statements in the World Access June 30 Form
10-Q for further description of this litigation.
 
     As part of the negotiations relating to the acquisition of NACT, World
Access and GST Telecommunications, Inc. agreed to share evenly any Aerotel
judgment against NACT, including NACT's legal fees. Subsequent to the NACT
Acquisition, World Access has been actively engaged in settlement negotiations.
On July 9, 1998, World Access, GST and Aerotel entered into a Memorandum of
Understanding to settle the Aerotel litigation. Including legal fees, World
Access now estimates its Aerotel settlement costs will be approximately $3.3
million. The settlement costs expected to be incurred by World Access have been
accounted for as additional NACT purchase price as of June 30, 1998.
 
IN-PROCESS RESEARCH AND DEVELOPMENT
 
     Overview.  The nature of the efforts required to develop the purchased
in-process technology into commercially viable products principally relate to
the completion of all planning, designing, prototyping, verification, and test
activities that are necessary to establish that the product can be produced to
meet its design specifications, including functions, features, and technical
performance requirements.
 
     The value of the purchased in-process technology was determined by
estimating the projected net cash flows related to such products, including
costs to complete the development of the technology and the future revenues to
be earned upon commercialization of the products. These cash flows were
discounted back to their net present value. The resulting projected net cash
flows from such projects were based on management's estimates of revenues and
operating profits related to such projects. These estimates were based on
several assumptions, including those summarized below for each respective
acquisition.
 
     If these projects to develop commercial products based on the acquired
in-process technology are not successfully completed the sales and profitability
of World Access may be adversely affected in future periods. Additionally, the
value of other intangible assets may become impaired.
 
     NACT.  NACT provides advanced telecommunications switching platforms with
integrated applications software and network telemanagement capabilities. NACT
designs, develops, and manufacturers all hardware and software elements
necessary for a fully integrated, turnkey telecommunications switching solution.
The nature of the in-process research and development was such that
technological feasibility had not been attained. Failure to attain technological
feasibility, especially given the high degree of customization required

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
for complete integration into the NACT solution, would have rendered partially
designed hardware and software useless for other applications. Incomplete design
of hardware and software coding would create a non-connective, inoperable
product that would have no alternative use.
 
     NACT's business plan called for a shift in market focus to larger
customers, both domestic and international; therefore, NACT had numerous
projects in development at the time of the acquisition. Additionally, the
pending completion of a major release of NACT's billing system required
significant development efforts to ensure continued integration with NACT's
product suite. The purchased in-process technology acquired in the NACT
acquisition was comprised of nine projects related to switching systems. These
projects were scheduled to be released between February 1998 and December 1999.
Most major projects had several ongoing sub-projects (e.g., a hardware design
project and a software design project). These projects included significant
redevelopment of some existing products and the creation of new products. The
research and development projects were at various stages of development. None of
the in-process projects considered in the write-off had attained technological
feasibility.
 
     Revenue attributable to in-process technology was assumed to increase in
the first five years of the twelve-year projection at annual rates ranging from
52.7% to 7.2%, decreasing over the remaining years at annual rates ranging from
- -2.7% to -61.2% as other products are released in the marketplace. Projected
annual revenue attributable to in-process technology ranged from approximately a
low of $6.3 million to a high of $117.2 million within the term of the
projections. These projections were based on assumed penetration of the existing
customer base, synergies as a result of the NACT acquisition, and movement into
new markets. Projected revenues from in-process technology were assumed to peak
in 2002 and decline from 2003 through 2009 as other new products are expected to
enter the market.
 
     In-process technology's contribution to the operating profit of NACT
(earnings before interest, taxes and depreciation and amortization) was
projected to grow within the projection period at annual rates ranging from a
high of 119.2% to a low of 11.0% during the first five years, decreasing during
the remaining years of the projection period similar to the revenue growth
projections described above. Projected in-process technology's annual
contribution to operating profit ranged from approximately $1.7 million to $34
million within the term of the projections.
 
     NACT estimates that the costs to develop the in-process technology acquired
in the NACT acquisition will be approximately $4.1 million in the aggregate
through the year 1999 ($3,249,000 in 1998 and $829,000 in 1999). The expected
sources of funding were scheduled research and development expenses from the
operating budget of NACT provided by the operating assets and liabilities of
NACT.
 
     ATI.  ATI develops and manufactures a series of high-performance digital
microwave/millimeter radio equipment. Their products reach across all frequency
bands and data rates and offer numerous features. The nature of the in-process
research and development was such that technological feasibility had not been
attained. Failure to attain technological feasibility would have rendered
partially designed equipment useless for other applications. ATI's products are
designed for specific frequency bandwidths and, as such, are highly customized
to those bandwidths and the needs of customers wishing to operate in them.
Products only partially completed for certain bandwidths cannot be used in other
bandwidths.
 
     Between each product line, various stages of development had been reached.
Additionally, within each product line, different units had reached various
stages of development. Of the products management considered in-process, none
had attained technological feasibility. The purchased-in-process technology
acquired in the ATI acquisition was comprised of three primary projects related
to high-performance, digital microwave/millimeter radio equipment. Each project
consists of multiple products. The majority of the products were scheduled to be
released during 1998 and 1999.
 
     Revenue attributable to in-process technology was estimated to increase
within the first three years of the seven-year projection at annual rates
ranging from a high of 240.7% to a low of 2.3%, decreasing within the
                                      F-37

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
remaining years at annual rates ranging from -30.9% to -60.9% as other products
are released in the marketplace. Projected annual revenue attributable to
in-process technology ranged from approximately a low of $10.1 million to a high
of $71.1 million within the term of the projections. These projections were
based on assumed penetration of the existing customer base, synergies as a
result of the ATI acquisition, and movement into new markets. Projected revenues
from in-process technology were assumed to peak in 2001 and decline from 2003
through 2004 as other new products are expected to enter the market.
 
     In-process technology's contribution to the operating profit of ATI
(earnings before interest, taxes and depreciation and amortization) was
estimated to grow within the projection period at annual rates ranging from a
high of 665.9% to a low of 43.9% during the first four years, decreasing during
the remaining years of the projection period similar to the revenue growth
projections described above. Projected in-process technology's annual
contribution to operating profit ranged from approximately a low of -$900,000 to
a high of $9.1 million within the term of the projections.
 
     ATI estimates that the costs to develop the in-process technology acquired
in the ATI acquisition will be approximately $24.3 million in the aggregate
through the year 2002 ($3.3 million, $7.2 million, $7.6 million, $5.1 million,
and $1.1 million in 1998, 1999, 2000, 2001, and 2002, respectively). The
expected sources of funding were scheduled R&D expenses from the operating
budget of ATI provided by the operating assets and liabilities of ATI.
 
UNAUDITED PRO FORMA COMBINED BALANCE SHEET:
 
NACT MINORITY INTEREST ADJUSTMENTS
 
     (A) The acquisition of the minority interest of NACT 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 the in-process research and development projects of NACT will be
expensed at the consummation of the NACT Merger. The amount of the one-time
non-recurring charge is expected to approximate $21.9 million. Since this charge
is directly related to the acquisition and will not recur, the Unaudited Pro
Forma Statements of Operations have been prepared excluding this charge. New
World Access has not determined the final allocation of the purchase price, and
accordingly, the amount ultimately determined may differ significantly from the
amounts shown below.
 
     The unallocated excess of purchase price over the net assets acquired is
determined as follows (in thousands):

restriction, (2) the number of shares subject to restriction, and (3) the
volatility of World Access common stock [the closing price on the announcement
date was $37.06 and the closing price on August 28, 1998 was $23.13, a 37.6%
reduction]. Management of New World Access believes the discount rate to be used
in valuing these restricted shares is appropriate and reasonable.

     In addition to the shares noted above, the former creditors and Renaissance
Partners will also be issued 7,500,000 restricted New World Access shares at the
closing (the "Escrowed Shares"). These shares will be immediately placed into
escrow and will be valued at par value only, or $75,000. As it becomes probable
that the conditions for release from escrow will be met, the fair market value
of the shares as measured at that time will be recorded as additional goodwill
and stockholders' equity, respectively.
 
     Specifically, the Escrowed Shares will be released in the amounts and on
the dates specified below if the sum of the EBITDA for Resurgens for the
performance periods set forth below equals or exceeds the Target EBITDA for such
performance period as set forth below:

January 1, 2000 to and including
  December 31, 2000 (the "Third

</TABLE>
 
     Notwithstanding the foregoing, if the Exchange Closing Date is (a) on or
after August 16, 1998 but prior to September 30, 1998, then the First
Performance Period shall commence on September 1, 1998 and shall terminate on
(and including) December 31, 1998 and the Target EBITDA with respect thereto
shall be reduced to $6,700,000, or (b) on or after September 30, 1998, then the
First Performance Period shall commence on the first day of the calendar month
in which the Exchange Closing occurs and shall terminate on (and including) the
last day of the sixth calendar month following the month in which the Exchange
Closing occurs, the release date shall be forty-five (45) days after the end of
such period and the Target EBITDA shall be equal to the sum of (i) $2,100,000
for each calendar month of 1998 included in the First Performance Period and
(ii) $2,400,000 for each calendar month of 1999 included in the First
Performance Period.
 
     If, after the Exchange, the EBITDA of Resurgens is less than the Target
EBITDA required for the release of Escrowed Shares in either of the First or
Second Performance Periods (and with respect to the Second Performance Period is
no less than zero), then, notwithstanding anything described herein, the
Escrowed Shares shall be released if the actual cumulative EBITDA for Resurgens
for such Performance Period and any subsequent Performance Periods equals or
exceeds the cumulative Target EBITDA for such Performance Periods.
 
     Notwithstanding anything to the contrary, (a) if during any calendar
quarter of the Second Performance Period, the closing price per share of the New
World Access Common Stock as reported by Nasdaq equals or exceeds $65.00 for any
five consecutive trading days during such calendar quarter, then 25% of all of
the shares of Escrowed Shares shall be released on February 15, 2000, provided
that if no Escrowed Shares are eligible for release during any such calendar
quarter, then such Escrowed Shares shall become eligible for release in a
subsequent calendar quarter of the Second Performance Period if the closing
price per share of the World Access Common Stock as reported by Nasdaq equals or
exceeds $65.00 for a total number of consecutive trading days during such
subsequent calendar quarter equal to or exceeding the total number of trading
days which such closing price was required to equal or exceed for (i) such
subsequent calendar quarter and (ii) each of the previous calendar quarters
beginning with the calendar quarter for which such Escrowed Shares were not
eligible for release; (b) if the EBITDA of Resurgens for the Second Performance
Period

equals or exceeds $52,775,000, then the Escrowed Shares related to the Third
Performance Period shall be released on February 15, 2000; and (c) all of the
Escrowed Shares shall be released upon a Change of Control (as defined in the
Exchange Agreement).
 
     (iii) The combined historical accounts of Resurgens include pre-petition
creditor liabilities of $334.5 million, which are classified as "liabilities
subject to compromise," and borrowings under the WorldCom debtor-in-possession
financing facility of $22.0 million as of June 30, 1998, respectively. These
liabilities will be satisfied in connection with the Plan of Reorganization,
which has been approved by the creditors committee and confirmed by the
bankruptcy court pursuant to an order dated September 3, 1998. Upon the closing
of the Transaction, the former creditors will receive shares of RCG common stock
in exchange for the surrender of all of their claims against RCG. Immediately
thereafter, the former creditors' shares of RCG will be cancelled and
automatically converted into the right to receive shares of New World Access
Common Stock, a portion of which will be received directly and a portion of
which will be deposited into escrow pending the satisfaction of certain
conditions. All such shares of New World Access Common Stock are subject to
certain contractual restrictions.
 
     The confirmation of the Plan of Reorganization is a condition precedent to
the closing of the Transaction. Therefore, the combined historical stockholders
deficit of $354.4 million as of June 30, 1998 has been adjusted to reflect a
$356.6 million reduction for the liabilities subject to compromise and the
WorldCom debtor-in-possession financing facility for purposes of the unaudited
pro forma combined balance sheet.
 
     (iv) Estimates of fair market value of the licenses and the switching
equipment acquired have been made by management. These estimates are subject to
adjustment pending final valuations to be obtained from independent appraisers.
 
     (v) At the time the Transaction is consummated, Resurgens is expected to
have in excess of $125 million in net operating loss carryforwards available to
offset future federal taxable income. Based on its current assessment of the
forecasted operating results of Resurgens and other pertinent factors,
management expects at least 35% of these future tax benefits will be realized.
Accordingly, a deferred tax asset of $44 million, net of a 65% valuation
allowance of approximately $29 million, has been reflected in the Pro Forma
Combined Balance Sheet. The amount of the valuation allowance is subject to
future analysis and may be revised prior to the closing of the Transaction.
 
     The pro forma loss of the combined entity is not indicative of the results
of operations that are expected to be achieved by the combined entity in the
future. The nature of Resurgens current operations are concentrated solely on
the international carriers' carrier business and an upgraded, efficient
operating network is now in place. Resurgens has a new, experienced management
team in place and has entered into several new contracts to increase its revenue
base, including a significant service contract with WorldCom Network Services,
Inc., a wholly owned subsidiary of WorldCom, Inc. Prior to the acquisition of
Resurgens, it is expected that Resurgens will be essentially debt free due to
its Chapter 11 bankruptcy proceedings. In addition, there are several closing
conditions that must be satisfied before the Resurgens Transaction is
consummated, including the achievement by Resurgens of monthly revenues of $25
million and related gross profit margin of greater than 5% for the calendar
month immediately preceding the closing date
 
     (D) Eliminate existing stockholders' equity.
 
TELCO PRO FORMA ADJUSTMENTS
 
     (E) The Telco Merger 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 the in-process
research and development projects of Telco will be expensed at the consummation
of the acquisition. The amount of the one-time non-recurring charge is expected
to approximate $73.9 million. Since this charge is directly related to the
acquisition and will not recur, the Unaudited Pro Forma Statements of Earnings
have been prepared excluding this charge. New World Access has not determined
the final allocation of the

</TABLE>
 
     (i) Based on the terms of the Telco Merger Agreement and the value of New
World Access Common Stock as of August 28, 1998, Telco stockholders are
currently expected to receive approximately 6.5 million freely tradeable shares
of New World Access Common Stock at the time of the Telco Merger. The value
assigned to these shares will be $29.26 per share, the seven trading days
average closing price of World Access Common Stock which include the three
trading days prior and the three trading days subsequent to June 4, 1998, the
date economic terms of the Telco Merger were announced.
 
     (ii) The net deferred tax asset of $16 million is comprised primarily of
gross temporary differences arising from the differences between book and tax
basis of certain assets and liabilities and for tax credits available to Telco
and New World Access. It is the opinion of management that these tax assets are
likely to be utilized by Telco or New World Access.
 
     (iii) The amount of in-process research and development costs has been
estimated by management based on factors considered such as the number of
projects in process, the potential alternative future uses of those projects and
estimated future projected revenues from those projects. The valuation of the
in-process research and development projects will be performed by an independent
valuation firm. The independent valuation of the in-process research and
development projects will be utilized in the final purchase price allocation.
 
     (F) Eliminate existing stockholders' equity.
 
     (G) Represents retained earnings adjustment for the one-time non-recurring
charge related to the write-off of in-process research and development expenses
