ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

         The full Management's Discussion and Analysis of Financial Condition
and Results of Operations is omitted under the reduced disclosure format
pursuant to General Instruction I(2)(a) of Form 10-K. The following analysis
represents an abbreviated version of management's analysis of the results of
operations for 1996, excluding the effects of the December 31, 1996 acquisition
of the Company described below, as compared to 1995.

         MFS Communications Company, Inc. was founded in 1987 and commenced
operations in 1988. Effective at 11:58 p.m. on December 31, 1996, WorldCom
acquired the Company pursuant to the Merger of HIJ Corp., a wholly-owned

         On August 12, 1996, MFS acquired UUNET through a merger of a
subsidiary of MFS with and into UUNET. UUNET is a leading worldwide provider of
a comprehensive range of Internet access options, applications, and consulting

         Communications Services. The Company's communications services
predominately result in monthly recurring revenues. The Company provides these
services in an expanding number of major metropolitan areas. The development of
the Company's businesses and the installation and expansion of its networks
require significant expenditures, a substantial portion of which is incurred
before the realization of revenues. These expenditures, together with the
associated early operating expenses, result in negative cash flow until an
adequate customer base is established. As this customer base grows, incremental
revenues are added with minimal additional expense, providing significant
contributions to cash flow. The Company also incurs ongoing capital
expenditures with respect to both existing and new networks which are directly
related to the installation of new revenue producing circuits. These costs vary
based on the specific type of circuit installed and the location of the
customer.

         The incurrence of significant initial development and roll out
expenses in advance of anticipated future revenues will continue to affect the
operating results of the communications services segment. Anticipated sales
growth in the communications services segment will also continue to drive
increasing deployment of electronic equipment required to initiate customer
service.

         Network Systems Integration Services. The Company, primarily through
MFS Network Technologies, designs, engineers, develops and manages the
installation of the Company's new fiber optic networks and network expansions.
In 1991, the Company began to offer network systems integration services to
third parties. These services have been characterized by significant revenues
concentrated in a relatively small number of large projects for third parties.
In 1993, the Company also began to offer services related to Intelligent
Transportation Systems ("ITS"). The Company recognizes revenue based upon the
amount of network systems integration services performed. The amount of the
Company's network systems integration services performed can vary on a
quarterly basis depending upon individual customer contract requirements.

YEAR ENDED DECEMBER 31, 1996 VS. YEAR ENDED DECEMBER 31, 1995

Communications Services

         Communications services revenue increased to $927.0 million in 1996
from $498.2 million in 1995, an increase of $428.8 million or 86%. The increase
resulted from the acquisition of UUNET as of August 12, 1996, which recorded
$135.1 million of revenue since that date, and from increased market
penetration of all communications services of the Company. Revenue from
international operations increased to $166.3 million in 1996 from $40.4 million
in 1995, reflecting strong sales in the United Kingdom and a growing revenue
base in continental Europe.

         Annualized monthly recurring revenue increased to approximately $1,387
million at December 31, 1996 from approximately $625 million at December 31,
1995, an increase of 122%. The increase reflects the sales of additional
services to current and new customers in existing and new markets and the
acquisition of UUNET. Monthly recurring revenue represents monthly service
charges billable to communications services customers as of the last day of the
period indicated, but excludes non-recurring revenues for certain one-time
services, such as installation fees or equipment charges.

         Communications services cost of sales increased to $512.7 million in
1996 from $244.2 million in 1995, an increase of $268.5 million. The increase
resulted from an increase of $76.6 million related to the acquisition of UUNET
as of August 12, 1996, and from increased market penetration of all
communications services of the Company. Communications services cost of sales
consist of direct third-party costs of providing communications services,
primarily payments to other telecommunications companies for access and
transport charges.

         Communications services depreciation and amortization expense
increased to $283.6 million in 1996 from $139.9 million in 1995, an increase of
$143.7 million. The increase is primarily related to amortization expense of
approximately $59.4 million on the intangible assets recorded in the UUNET
acquisition and to the expanded fixed asset base of the Company's networks.

         Communications services selling, general and administrative expenses
increased to $498.8 million in 1996 from $348.2 million in 1995, an increase of
$150.6 million. The increase resulted from an increase of $46.5 million related
to the acquisition of UUNET, $21.2 million of costs related to the Merger, and
from increased costs related to the Company's continued growth.

         The Company recognized a $1.4 billion charge for in-process research
and development in 1996 related to the acquisition of UUNET. The charge is
based upon a valuation analysis of the technologies of the Internet network
expansion system of UUNET and certain other identified research and development
projects purchased in the acquisition. The Company believes that the efforts to
complete these projects will consist of internally-staffed engineering costs
and further development and construction of the network. These costs are
estimated to be approximately $1.0 billion and will be incurred over the next
five years.

Network Systems Integration Services

         Third party revenue from services offered by the Company's network
systems integration segment increased to $188.0 million in 1996 from $85.0
million in 1995 or 121%. The increase is due to an increase in the number of
new projects, including contracts to provide design and construction services
for a wireless personal communications system and a fiber-optic network along
the trans-Alaska pipeline.





                                       5

<PAGE>   9


         Network systems integration cost of sales increased to $174.3 million
in 1996 from $73.6 million in 1995, an increase of $100.7 million. The increase
is primarily due to the increased level of costs related to the projects noted
above, including the continuing development and investment in ITS service
projects. Network systems integration cost of sales consist of direct costs
associated with the network systems integration projects.

         Network systems integration selling, general and administrative
expenses increased to $15.7 million in 1996 from $14.0 million in 1995, an
increase of $1.7 million. The increase reflects the increased number of new
projects in 1996.

Other Income (Expense)

         Other income (expense) increased to $(64.8) million of other expense
in 1996 from $(28.0) million of other expense in 1995. The increase in other
expense resulted primarily from additions to interest expense incurred in
connection with the issuance of the 1996 Senior Discount Notes. This increase
was partially offset by increased interest income from the investment of the
proceeds from the sale of the 1996 Senior Discount Notes and the common stock
offering in 1996.

Income Taxes

         The income tax expense of $0.5 million and $0.6 million for 1996 and
1995, respectively, resulted from estimated state and foreign tax liabilities.

Net Loss

         Net loss increased to $1,838.0 million in 1996 from $267.9 million in
1995, an increase of $1,570.1 million. The increase resulted primarily from the
write off of acquired research and development and increased depreciation,
amortization and interest expense.

Backlog

         The network systems integration and facilities management services
segment had third party backlog of approximately $259 million at December 31,
1996. Backlog consists of firm contracts less revenue recognized to date by the
Company.

Forward-looking Statements

         The matters discussed in this Form 10-K contain forward-looking
statements, within the meaning of the Private Securities Litigation Reform Act
of 1995, that involve risks and uncertainties including risk of changing market

Company. It should be recognized that other risks may be significant, presently
or in the future.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Stockholder and Board of Directors
   of MFS Communications Company, Inc.:

We have audited the accompanying consolidated balance sheet of MFS
Communications Company, Inc. and Subsidiaries (a wholly-owned subsidiary of
WorldCom, Inc.) as of December 31, 1996, and the related consolidated statement
of operations, changes in stockholder's equity and cash flows for the period
then ended (see Note 1). 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 audit.

We conducted our audit 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 also 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 audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of MFS
Communications Company, Inc. and Subsidiaries as of December 31, 1996, and the
consolidated results of its operations and its cash flows for the period then
ended in conformity with generally accepted accounting principles.

               MFS COMMUNICATIONS COMPANY, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

1.   ORGANIZATION:

         The consolidated financial statements include the accounts of MFS
Communications Company, Inc. ("MFS"), and its majority-owned subsidiaries (the
"Company"). Effective at 11:58 p.m. on December 31, 1996 ("Inception"),
WorldCom, Inc. ("WorldCom") acquired the Company pursuant to the merger (the
"Merger") of HIJ Corp., a wholly-owned subsidiary of WorldCom, with and into
MFS. Upon consummation of the Merger, the Company became a wholly-owned
subsidiary of WorldCom. Pursuant to the merger agreement, each share of the
Company's common stock was converted into the right to receive 2.1 shares of
common stock of WorldCom, and each share of the Company's Series A and Series B
Preferred Stock was converted into the right to receive one share of WorldCom
Series A and Series B Preferred Stock, respectively. Upon the Merger the
capital structure of the Company consists of one share of common stock which is
owned by WorldCom and constitutes all of the issued and outstanding capital
stock.

         The acquisition of the Company has been accounted for by WorldCom
using the purchase method. The results of applying that method have been pushed
down into the Company's financial statements at the date of the Merger.
Accordingly, the consolidated balance sheet as of December 31, 1996 reflects
the allocation of the purchase price to the Company's assets and liabilities
based upon their estimated fair values. The initial purchase price allocation
for the Merger is based on current estimates and WorldCom will make the final
purchase price allocation based upon final values for certain assets and
liabilities. As a result, the final purchase price allocations may differ from
the presented estimate. The excess of cost over the fair value of net tangible
assets, identifiable intangible assets and in-process research and development
of the Company has been recorded as goodwill. The value assigned to the
in-process research and development has been charged to expense in the
consolidated statement of operations for the period ended December 31, 1996.
The results of operations reflect only the recording of the charge for
in-process research and development which represents the Company's only
activity for 1996 subsequent to the acquisition by WorldCom. The results of
operations of the Company for the period from Inception to December 31, 1996,
are not indicative of results of operations for a full fiscal year.

         The Company operates through its subsidiaries in two business
segments, communications services and network systems integration services. The
communications segment is comprised of the MFS Telecom Companies, which provide
telecommunications services to large business and government customers, the MFS
Intelenet Companies, which provide telecommunications services to small and
medium sized business customers, MFS International, which provides
telecommunications services to business and government customers
internationally and MFS Global Network Services, which manages the Company's
international network platform. With the acquisition of UUNET Technologies,
Inc. ("UUNET") on August 12, 1996, the Company also provides Internet-related
communications services to customers. The network systems integration segment
provides services primarily through MFS Network Technologies.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

(a)   Principles of Consolidation:

         The consolidated financial statements of the Company include the
accounts of all of its majority-owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated.



                                      13

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:--(CONTINUED)

(b)   Recognition of Revenue:

         The Company recognizes revenue on communications services in the month
the related service is provided. Network systems integration revenue is
recognized on the percentage-of-completion method of accounting. Under the
percentage-of-completion method, an estimated percentage for each contract, as
determined by the Company's engineering estimate based on the amount of work
performed, is applied to total estimated profit. Provisions for losses are
recognized on uncompleted contracts when they become known. Claims for
additional revenue are recognized in the period when settled. Revisions in cost
and profit estimates, which are always reasonably possible to occur in the near
term under the percentage-of-completion method, are reflected in the accounting
period in which the facts which require the revision become known.

(c)   Cost of Sales:

         Cost of sales includes direct third-party costs of providing
communications services, primarily payments to other telecommunications
companies for access and transport charges, and the costs of providing network
systems integration services under the percentage-of-completion method of
accounting.

(d)   Classification of Current Assets and Liabilities:

         In accordance with industry practice, amounts realizable and payable
under network systems integration contracts which may extend beyond one year
are includable in current assets and liabilities. A one year time period is
used as the basis for classification of all other current assets and
liabilities.

(e)   Networks and Equipment:

         The networks and equipment are stated at cost as adjusted by the
Merger described in Note 1. Various costs are capitalized during the
installation and expansion of the networks. Provisions for depreciation are
computed using straight-line methods over estimated useful lives beginning in
the year an asset is put into service.

         Electronic and related equipment, leasehold improvements, furniture
and office equipment and land and buildings are stated at cost as adjusted by
the Merger described in Note 1. Leasehold improvements primarily consist of
extensions off the network to customer locations. Depreciation is computed
using primarily straight-line methods over the estimated useful lives of the
assets or, for capital leases, the term of the related leases.

         Costs of purchased software and certain costs to modify and improve
certain of the Company's computer software are recorded at cost as adjusted by
the Merger described in Note 1 and are being amortized using the straight-line
method over their estimated useful lives.

(f)   Intangible Assets:

         Goodwill, including goodwill arising from the Merger described in Note
1, is being amortized over periods ranging from five to 40 years from the dates
of acquisition. The Company reviews the carrying amount of goodwill for
impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. Measurement of any impairment would
include a comparison of estimated future operating cash flows anticipated to be
generated during the remaining life of the goodwill to the net carrying value
of the goodwill.

                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:--(CONTINUED)

(f)   Intangible Assets:--(continued)

         Intangibles identified in the Merger, including developed technology
and the assembled workforce, will be amortized over five years and 10 years,
respectively. Costs incurred in developing new networks or expanding existing
networks, including network design, negotiation of rights-of-way and obtaining
legal/regulatory authorizations are deferred and amortized over five years.

         Costs incurred to obtain access to buildings are deferred by the
Company and amortized over 15 years. Costs incurred to obtain city franchises
are deferred by the Company and amortized over the initial term of the
franchise.

         Pre-operating costs represent substantially all nondevelopment costs
incurred during the pre-operating phase of a newly-constructed network and are
amortized over five-year periods commencing with the start of operations.

         Costs incurred to implement the Company's program to take advantage of
the opportunities presented by the passage of the Telecommunications Act of
1996 have been deferred and amortized over five years. Costs incurred to
provision service to new customers and new services to current customers has
been deferred and amortized over five years.

         The costs of rights-of-way and customer lists obtained in business
acquisitions are being amortized over estimated useful lives of 20 to 25 years
and three years, respectively.

         During 1996, the Company recorded a $2.14 billion charge for
in-process research and development related to the Merger. The charge is based
upon a valuation analysis of the technologies of the Company's worldwide
information system, the Internet network expansion system of UUNET and certain
other identified research and development projects purchased in the Merger. At
the date of the Merger, the technological feasibility of the acquired
technology had not yet been established and the technology has no future
alternative uses.

(g)   Income Taxes:

         As a result of the Merger, the Company is considered the surviving
entity for tax reporting purposes. Accordingly, the Company's consolidated tax
returns will include WorldCom as a subsidiary for tax reporting purposes.
Income taxes will be recognized by each entity within the consolidated group in
proportion to their contribution to consolidated taxable income. The Company
recognizes deferred tax liabilities and assets for the expected future tax
consequences of events that have been included in the financial statements or
tax returns. Under this method, deferred tax assets and liabilities are
determined based on the difference between the financial statement and tax
bases of assets and liabilities using enacted tax rates in effect for the year
in which the differences are expected to reverse.

(h)   Minority Interest:

         The Company has recorded the entire loss of other than wholly-owned
subsidiaries where the loss applicable to the minority interest exceeds the
minority interest in such subsidiaries' equity.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:--(CONTINUED)

(i)   Translation of Foreign Financial Statements:

         Assets and liabilities are translated into U.S. dollars at year-end
exchange rates. Revenues and expenses will be translated using the average
rates of exchange for the period. Gains or losses resulting from foreign
currency translation will be recorded as adjustments to stockholder's equity.

(j)   Cash Equivalents:

         Cash equivalents generally consist of highly liquid debt instruments
purchased with a maturity of three months or less.

(k)   Marketable Securities:

         Marketable securities are being carried at fair value.

(l)   Financial Instruments:

         Financial instruments which potentially subject the Company to
concentration of credit risk consist principally of marketable securities and
accounts receivable. Concentrations of credit risk of marketable securities are
limited due to investments in short-term, investment grade securities.
Concentrations of credit risk with respect to accounts receivable are limited
due to the dispersion of the Company's customer base among different industries
and geographic areas and remedies provided by terms of contracts and statutes.

(m)   Loss Per Share:

         The Company has not presented loss per share for the period from
Inception to December 31, 1996, because of the change in capital structure
described in Note 1.

(n)   Estimates in Consolidated Financial Statements:

         The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

3.   FINANCIAL INSTRUMENTS:

         The following methods and assumptions were used to determine the
classification and fair value of each class of financial instruments for which
it is practicable to estimate that value:

(a)   Cash and Cash Equivalents:

         Cash equivalents generally consist of highly liquid debt instruments
purchased with a maturity of three months or less and are carried at fair value
which approximates cost due to the short maturities.

3.   FINANCIAL INSTRUMENTS:--(CONTINUED)

(b)   Marketable Securities:

         The Company has classified all marketable securities other than cash
equivalents as available-for-sale. As described in Note 1, at December 31,
1996, the Company recorded its assets and liabilities at estimated fair values,
therefore the amortized cost of the Company's marketable securities equals the
estimated fair value on that date. The amortized costs of the securities to be
used in computing unrealized and realized gains and losses will be determined
by specific identification. Fair values are estimated based on quoted market
prices.

         Marketable securities at December 31, 1996 are as follows:

         As described in Note 1, at December 31, 1996, the Company recorded its
assets and liabilities at estimated fair values, therefore the Company's
long-term debt is recorded at estimated fair value. Fair value is estimated
based on the quoted market price for the same or similar issues or on borrowing
rates currently available to the Company for debt with similar terms and
maturities.

6.   NOTES PAYABLE AND LONG-TERM DEBT:--(CONTINUED)

 (a)  The 1994 Senior Discount Notes:

         The Company issued the 1994 Senior Discount Notes (the "1994 Notes")
in January 1994 and recorded the net proceeds, exclusive of transaction costs,
of approximately $500,000 as long-term debt. The 1994 Notes were issued with an
effective interest rate of 9 3/8%. As described in Note 1, upon the Merger the
liabilities of the Company were adjusted to market value, which changed the
effective interest rate for the 1994 Notes to approximately 8.6%. The Company
is accruing to the principal amount of the 1994 Notes of $788,320 through
January 1999. Cash interest will not accrue on the 1994 Notes prior to January
15, 1999, however, the Company may elect to commence the accrual of cash
interest at any time prior to that date. Commencing July 15, 1999 cash interest
will be payable semi-annually.

         On or after January 15, 1999, the 1994 Notes will be redeemable at the
option of the Company, in whole or in part from time to time, at the following
prices (expressed in percentages of the principal amount at the stated
maturity), if redeemed during the twelve months beginning January 15 of the
years indicated below, in each case together with interest accrued to the
redemption date.

          2000.......................................................       102.34%
          2001.......................................................       101.17%
          2002 and thereafter........................................       100.00%
</TABLE>

         In addition, due to certain conditions related to the change in
control of the Company that occurred as of the Merger, the Company was required
to offer to repurchase all or any part of the 1994 Notes as stipulated in the
note agreement. The offer to repurchase the 1994 Notes expired February 27,
1997, with an immaterial amount of the 1994 Notes being repurchased. The 1994
Notes are senior unsecured obligations of the Company and are subordinated to
all current and future indebtedness of the Company's subsidiaries, including
trade accounts payable. The 1994 Notes contain certain covenants which, among
other things, restrict the Company's ability to incur additional debt, create
liens, enter into sale and leaseback transactions, pay dividends, make certain
restricted payments, enter into transactions with affiliates, and sell assets
or merge with another company.

(b)   The 1996 Senior Discount Notes:

         The Company issued the 1996 Senior Discount Notes (the "1996 Notes")
in January 1996 and recorded the net proceeds, exclusive of transaction costs,
of approximately $600,000 as long-term debt. The 1996 Notes were issued with an
effective interest rate of 8 7/8%. As described in Note 1, upon the Merger the
liabilities of the Company were adjusted to market value, which changed the
effective interest rate for the 1996 Notes to approximately 8.4%. The Company
is accruing to the principal amount of the 1996 Notes of $924,000 through
January 2001. Cash interest will not accrue on the 1996 Notes prior to January
15, 2001, however, the Company may elect to commence the accrual of cash
interest at any time prior to that date. Commencing July 15, 2001, cash
interest will be payable semi-annually.

option of the Company, in whole or in part from time to time, at the following

</TABLE>

         In addition, due to certain conditions related to the change in
control of the Company that occurred as of the Merger, the Company was required
to offer to repurchase all or any part of the 1996 Notes as stipulated in the
note agreement. The offer to repurchase the 1996 Notes expired on February 27,
1997, with an immaterial amount of the 1996 Notes being repurchased. The 1996
Notes are senior unsecured obligations of the Company with a ranking equal to
the 1994 Notes and are subordinated to all current and future indebtedness of
the Company's subsidiaries, including trade accounts payable. The 1996 Notes
contain covenants similar to the 1994 Notes.

(c)   The Vendor Credit Facilities:

         In July 1995, the Company established two credit facilities to borrow
up to an aggregate of $120 million for purchases of switching equipment through
mid-1997 (the "Vendor Credit Facilities"). The facilities are collateralized by
the purchased equipment and partially guaranteed by the Swedish Export Credits
Guarantee Board and the equipment manufacturer. Borrowings under the Vendor
Credit Facilities are scheduled to be repaid under various schedules, through
2002. The Company may repay any amounts borrowed under the facilities without
premium or penalty at any time.

         The Vendor Credit Facilities provide for interest at a variable rate
and a commitment fee on any unused balances. The Vendor Credit Facilities
contain certain financial covenants and other restrictions similar to the 1994
Notes. Subsequent to year end, the Company determined to pay off the
outstanding balance of the Vendor Credit Facilities.

(d)   Equipment Finance Agreement:

         In 1996, the Company entered into a $20,000 loan agreement with an
equipment manufacturer and a bank. The loan, which includes interest at a
variable rate, must be used to purchase equipment supplied by the manufacturer.
The loan must be repaid in semi-annual installments of $2,000 started June 20,
1996, and is collateralized by the equipment purchased. The agreement contains
certain financial covenants and restrictions similar to the 1994 Notes.

6.   NOTES PAYABLE AND LONG-TERM DEBT:--(CONTINUED)

(e)   Equipment Debt:

         In connection with the acquisition of UUNET in the third quarter of
1996, the Company assumed long-term debt of approximately $34,429. This debt is
primarily related to an agreement between Microsoft Corporation ("Microsoft")
and UUNET that provides for the purchase of equipment used in the construction
of a network to be used by both parties. Principal and interest, at the higher
of 7.74% or the applicable federal rate at the time of an advance are payable
to Microsoft on each advance quarterly over five years. Borrowings under the
agreement are collateralized by the equipment purchased.

7.   LEASES:

         Capitalized leases consist primarily of leases of electronic
telecommunications equipment. The Company is also leasing premises under
various operating leases which, in addition to rental payments, require
payments for insurance, maintenance, property taxes and other executory costs
related to the leases. Certain leases provide for adjustments in lease cost
based upon adjustments in the consumer price index and increases in the
landlord's management costs. The lease agreements have various expiration dates
and renewal options through 2014.

         Future minimum payments by year and in the aggregate, under the
capital leases and non cancelable operating leases with initial or remaining
terms of one year or more consist of the following at December 31, 1996:

         There was no rent expense under lease agreements for the period from
Inception to December 31, 1996.

8.   COMMITMENTS AND CONTINGENCIES:

         Under the terms of stockholder agreements, from time to time, minority
stockholders in certain subsidiaries have the option to put shares to the
Company at a purchase price equal to an appraised value of such shares.

         The Company has issued standby letters of credit to various city
governmental agencies and building lessors, amounting to approximately $5,453
at December 31, 1996. It is management's belief that the underlying obligations
will be met in the normal course of business without material adverse effect on
the Company's financial position.

         The Company is also obligated under rights-of-way and franchise
agreements with various entities for the use of their rights-of-way for the
installation of its telecommunications systems.

8.   COMMITMENTS AND CONTINGENCIES:--(CONTINUED)

         Pursuant to an agreement with a joint venture, the Company is
obligated to invest up to $75,000 over the next two years in the form of
capital contributions and to pay $60,000 over the next four years to purchase
an indefeasible right of use for certain undersea capacity between the United
States and Europe that is being constructed by the joint venture. The Company
is also a party to the joint venture.

         The Company is also involved in various other claims and regulatory
proceedings incidental to its business. Management believes that any resulting
liability beyond that provided should not materially affect the Company's
financial position, results of operations or cash flows.

9.   INCOME TAXES:

         At December 31, 1996, the Company had net operating loss ("NOL")
carryforwards for income tax purposes of approximately $924,000 which expire in
years 1997 through 2011. The existing NOL carryforwards of the Company can be
used to offset future taxable income of the Company and its tax subsidiaries,
including WorldCom. The consideration of WorldCom's historical and projected
levels of taxable income make the realization of a substantial portion of the
Company's NOL carryforwards more likely than not. A valuation reserve has been
recognized to offset certain deferred tax assets related to net operating loss
carryforwards due to the uncertainty of realizing the benefit of those loss
carryforwards.

         The components of deferred taxes at December 31, 1996 are as follows:

10.  EMPLOYEE BENEFIT PLANS:

         Certain of the Company's employees have received benefits under plans
that have been assumed by WorldCom. A description of those plans follow.

(a)   401(k) Plan:

         The Company administers a 401(k) Plan whereby eligible employees may
voluntarily contribute a percentage of compensation. The Company has not
contributed to the plan. Full-time employees who have attained 21 years of age
are eligible to participate.

10.  EMPLOYEE BENEFIT PLANS:--(CONTINUED)

(b)   Stock Option Plans:

         Certain employees of the Company have received stock options under
plans that have been assumed by WorldCom. Upon effectiveness of the Merger, the
then outstanding and unexercised options exercisable for shares of the
Company's common stock were converted into options exercisable for shares of
WorldCom common stock having substantially the same terms and conditions as the
Company's options, except that the exercise price and the number of shares
issuable upon exercise were divided and multiplied, respectively, by 2.1.

(c)   Shareworks:

         Effective October 1995, the Company implemented a new employee benefit
plan which is comprised of a grant plan and a match plan jointly known as
Shareworks. This employee benefit plan was also assumed by WorldCom. The plan
was offered to each domestic employee hired after September 1, 1995, and also
made available to all current employees that choose to be ineligible for future
grants under the Company's Stock Option Plans. The grant plan enables the
Company to grant shares of the Company's common stock to eligible employees
based upon a percentage of the employee's eligible pay, up to 5%. The original
grant will vest after three years with any additional grants vesting
immediately once the initial three year period has been met.

         The match plan allows eligible employees to defer between 1% and 10%
of eligible pay to purchase common stock of the Company at the stock price on
each pay period date. The Company will match the shares purchased by the
employee on a one-for-one basis. The stock which is credited to each employee's
account to match the employee's purchase during any calendar quarter, vests
three years after the end of that quarter.

         The unamortized compensation expense for the Shareworks plan has been
recorded as a deferred charge in stockholder's equity in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees."

11.  SEGMENT INDUSTRY DATA:

         The Company operates in two reportable segments primarily within the
United States: communications services and network systems integration
services. A summary of the Company's identifiable assets by segment at December
31, 1996 is as follows:

               MFS COMMUNICATIONS COMPANY, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

1.   ORGANIZATION:

         The consolidated financial statements include the accounts of MFS
Communications Company, Inc. ("MFS"), and its majority-owned subsidiaries (the
"Company"). MFS was incorporated on July 17, 1987 in Delaware and, prior to its
initial public offering in May 1993, was a wholly-owned subsidiary of Kiewit
Diversified Group Inc. ("KDG"), which is a wholly-owned subsidiary of Peter
Kiewit Sons', Inc. ("PKS"). In 1995, pursuant to a planned restructuring, all
of PKS' remaining interest in the Company's capital stock was distributed to
certain PKS stockholders.

         Effective at 11:58 p.m. on December 31, 1996 ("Inception"), WorldCom,
Inc. ("WorldCom") acquired the Company pursuant to the merger (the "Merger") of
HIJ Corp., a wholly-owned subsidiary of WorldCom, with and into MFS. Upon
consummation of the Merger, the Company became a wholly-owned subsidiary of
WorldCom. Pursuant to the merger agreement, each share of the Company's common
stock was converted into the right to receive 2.1 shares of common stock of
WorldCom, and each share of the Company's Series A and Series B Preferred Stock
was converted into the right to receive one share of WorldCom Series A and
Series B Preferred Stock, respectively. The capital structure of the Company as
of December 31, 1996, consists of one share of common stock which is owned by
WorldCom and constitutes all of the issued and outstanding capital stock.

         The acquisition of the Company has been accounted for by WorldCom
using the purchase method. Thus, the results of operations reflect the activity
of the Company up to the Merger. The impact of pushdown accounting reflecting
the purchase by WorldCom has been set forth in a separate report for ease of
understanding.

         The Company operates through its subsidiaries in two business
segments, communications services and network systems integration services. The
communications segment is comprised of the MFS Telecom Companies, which provide
telecommunications services to large business and government customers, the MFS
Intelenet Companies, which provide telecommunications services to small and
medium sized business customers, MFS International, which provides
telecommunications services to business and government customers
internationally and MFS Global Network Services, which manages the Company's
international network platform. With the acquisition of UUNET Technologies,
Inc. ("UUNET") on August 12, 1996, the Company also provides Internet-related
communications services to customers. The network systems integration segment
provides services primarily through MFS Network Technologies.

         Where appropriate, items within the consolidated financial statements
and notes thereto have been reclassified from previous years to conform to
current year presentation.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

(a)   Principles of Consolidation:

         The consolidated financial statements of the Company include the
accounts of all of its majority-owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:--(CONTINUED)

(b)   Recognition of Revenue:

         The Company recognizes revenue on communications services in the month
the related service is provided. Network systems integration revenue is
recognized on the percentage-of-completion method of accounting. Under the
percentage-of-completion method, an estimated percentage for each contract, as
determined by the Company's engineering estimate based on the amount of work
performed, is applied to total estimated profit. Provisions for losses are
recognized on uncompleted contracts when they become known. Claims for
additional revenue are recognized in the period when settled. Revisions in cost
and profit estimates, which are always reasonably possible to occur in the near
term under the percentage-of-completion method, are reflected in the accounting
period in which the facts which require the revision become known.

(c)   Cost of Sales:

         Cost of sales includes direct third-party costs of providing
communications services, primarily payments to other telecommunications
companies for access and transport charges, and the costs of providing network
systems integration services under the percentage-of-completion method of
accounting.

(d)   Classification of Current Assets and Liabilities:

         In accordance with industry practice, amounts realizable and payable
under network systems integration contracts which may extend beyond one year
are includable in current assets and liabilities. A one-year time period is
used as the basis for classification of all other current assets and
liabilities.

(e)   Networks and Equipment:

         The networks and equipment are stated at cost. Various costs are
capitalized during the installation and expansion of the networks. Provisions
for depreciation are computed using straight-line methods over estimated useful
lives beginning in the year an asset is put into service.

         Electronic and related equipment, leasehold improvements, furniture
and office equipment and land and buildings are stated at cost. Leasehold
improvements primarily consist of extensions off the network to customer
locations. Depreciation is computed using primarily straight-line methods over
the estimated useful lives of the assets or, for capital leases, the term of
the related leases.

         Costs of purchased software and certain costs to modify and improve
certain of the Company's computer software are recorded at cost and are being
amortized using the straight-line method over their estimated useful lives.

(f)   Intangible Assets:

         Goodwill is being amortized over periods ranging from five to 40 years
from the dates of acquisition. The Company reviews the carrying amount of
goodwill for impairment whenever events or changes in circumstances indicate
that the carrying amount may not be recoverable. Measurement of any impairment
would include a comparison of estimated future operating cash flows anticipated
to be generated during the remaining life of the goodwill to the net carrying
value of the goodwill.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:--(CONTINUED)

(f)   Intangible Assets:--(continued)

         Costs incurred in developing new networks or expanding existing
networks, including network design, negotiation of rights-of-way and obtaining
legal/regulatory authorizations are deferred and amortized over five years.

         Costs incurred to obtain access to buildings are deferred by the
Company and amortized over 15 years. Costs incurred to obtain city franchises
are deferred by the Company and amortized over the initial term of the
franchise.

         Pre-operating costs represent substantially all nondevelopment costs
incurred during the pre-operating phase of a newly-constructed network and are
amortized over five-year periods commencing with the start of operations.

         Costs incurred to implement the Company's program to take advantage of
the opportunities presented by the passage of the Telecommunications Act of
1996 have been deferred and amortized over five years. Costs incurred to
provision service to new customers and new services to current customers has
been deferred and amortized over five years.

         The costs of rights-of-way and customer lists obtained in business
acquisitions are being amortized over estimated useful lives of 20 to 25 years
and three years, respectively.

         In 1996, the Company recorded a $1.4 billion charge for in-process
research and development related to the acquisition of UUNET. The charge is
based upon a valuation analysis of the technologies of the Internet network
expansion system of UUNET and certain other identified research and development
projects purchased in the acquisition. At the date of the acquisition of UUNET,
the technological feasibility of the acquired technology had not yet been
established and the technology has no future alternative uses.

(g)   Income Taxes:

         The Company recognizes deferred tax liabilities and assets for the
expected future tax consequences of events that have been included in the
financial statements or tax returns. Under this method, deferred tax
liabilities and assets are determined based on the difference between the
financial statement and tax bases of liabilities and assets using enacted tax
rates in effect for the year in which the differences are expected to reverse.

(h)   Minority Interest:

         The Company has recorded the entire loss of other than wholly-owned
subsidiaries where the loss applicable to the minority interest exceeds the
minority interest in such subsidiaries' equity.

(i)   Translation of Foreign Financial Statements:

         Assets and liabilities are translated into U.S. dollars at year-end
exchange rates. Revenues and expenses are translated using the average rates of
exchange for the period. Gains or losses resulting from foreign currency
translation are recorded as adjustments to stockholders' equity.

(j)   Cash Equivalents:

         Cash equivalents generally consist of highly liquid debt instruments
purchased with a maturity of three months or less.

                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:--(CONTINUED)

(k)   Marketable Securities:

         Marketable securities are being carried at fair value.

(l)   Financial Instruments:

         Financial instruments which potentially subject the Company to
concentration of credit risk consist principally of marketable securities and
accounts receivable. Concentrations of credit risk of marketable securities are
limited due to investments in short-term, investment grade securities.
Concentrations of credit risk with respect to accounts receivable are limited
due to the dispersion of the Company's customer base among different industries
and geographic areas and remedies provided by terms of contracts and statutes.

(m)   Loss Per Share:

         The weighted average number of shares  outstanding for the years ended
December 31, 1996, 1995 and 1994 were 166,432,000, 127,786,000 and
124,874,000, respectively.

(n)   Estimates in Consolidated Financial Statements:

         The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those
estimates.

(o)   Stock-Based Compensation:

         In the first quarter of 1996, the Company adopted the accounting
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 method of accounting for their stock-based compensation
plans. Under the fair value based method, compensation cost for stock-based
compensation plans is measured at the grant date based on the fair value of the
award and is recognized over the service period, which for the Company is the
vesting period.

3.   FINANCIAL INSTRUMENTS:

         The following methods and assumptions were used to determine the
classification and fair value of each class of financial instruments for which
it is practicable to estimate that value:

(a)   Cash and Cash Equivalents:

         Cash equivalents generally consist of highly liquid debt instruments
purchased with a maturity of three months or less and are carried at fair value
which approximates cost due to the short maturities.

(b)   Marketable Securities:

         The Company has classified all marketable securities other than cash
equivalents as available-for-sale. The amortized costs of the securities used
in computing unrealized and realized gains and losses are determined by
specific identification. Fair values are estimated based on quoted market
prices. Net unrealized gains and losses are reported as a separate component of
stockholders' equity. The Company has not invested in derivative financial
instruments.

(a)   The Senior Discount Notes:

         The Company issued the Senior Discount Notes (the "1994 Senior
Discount Notes") on January 19, 1994 and recorded the net proceeds, exclusive
of transaction costs, of approximately $500,000 as long-term debt. The Company
is accruing to the principal amount of the 1994 Senior Discount Notes of
$788,320 through January 1999. Cash interest will not accrue on the 1994 Senior
Discount Notes prior to January 15, 1999, however, the Company may elect to
commence the accrual of cash interest at any time prior to that date.
Commencing July 15, 1999 cash interest will be payable semi-annually.

(a)   The Senior Discount Notes:--(continued)

         On or after January 15, 1999, the 1994 Senior Discount Notes will be
redeemable at the option of the Company, in whole or in part from time to time,
at the following prices (expressed in percentages of the principal amount at
the stated maturity), if redeemed during the twelve months beginning January 15
of the years indicated below, in each case together with interest accrued to
the redemption date.

2001 ...................      101.17%
2002 and thereafter ....      100.00%
</TABLE>

         In addition, under certain conditions related to a change in control
of the Company, the Company may be required to repurchase all or any part of
the 1994 Senior Discount Notes as stipulated in the note agreement. The 1994
Senior Discount Notes are senior unsecured obligations of the Company and are
subordinated to all current and future indebtedness of the Company's
subsidiaries, including trade accounts payable. The 1994 Senior Discount Notes
contain certain covenants which, among other things, restrict the Company's
ability to incur additional debt, create liens, enter into sale and leaseback
transactions, pay dividends, make certain restricted payments, enter into
transactions with affiliates, and sell assets or merge with another company.

(b)   The Credit Facilities:

         In April 1995, the Company reached agreement with a syndicate of
commercial banks for an aggregate of $250,000 of revolving credit facilities
(the "Credit Facilities"). The Credit Facilities were canceled during 1996.

(c)   The Vendor Credit Facilities:

         In July 1995, the Company established two credit facilities to borrow
up to an aggregate of $120 million for purchases of switching equipment through
mid-1997 (the "Vendor Credit Facilities"). The facilities are collateralized by
the purchased equipment and partially guaranteed by the Swedish Export Credits
Guarantee Board and the equipment manufacturer. Borrowings under the Vendor
Credit Facilities will be repaid under various schedules, through 2002. The
Company may repay any amounts borrowed under the facilities without premium or
penalty at any time.

         The Vendor Credit Facilities provide for interest at a variable rate
and a commitment fee on any unused balances. The Vendor Credit Facilities
contain certain financial covenants and other restrictions similar to the 1994
Senior Discount Notes.

(d)   The Notes Payable:

         In April 1995, the Company extended the maturity dates on the Notes
Payable to bank from 1995 to 1999.  During 1996 this Note Payable was paid off.
In connection with an acquisition in 1995, the Company assumed the Note Payable
to credit corporation.

7.   LEASES:

         Capitalized leases consist primarily of leases of electronic
telecommunications equipment. The Company is also leasing premises under
various operating leases which, in addition to rental payments, require
payments for insurance, maintenance, property taxes and other executory costs
related to the leases. Certain leases provide for adjustments in lease cost
based upon adjustments in the consumer price index and increases in the
landlord's management costs.

         Rent expense under lease agreements was $44,242 in 1996, $27,150 in
1995 and $17,789 in 1994.

8.   COMMITMENTS AND CONTINGENCIES:

         Under the terms of stockholder agreements, from time to time, minority
stockholders in certain subsidiaries have the option to put shares to the
Company at a purchase price equal to an appraised value of such shares.

         The Company has issued standby letters of credit to various city
governmental agencies and building lessors, amounting to approximately $5,453
at December 31, 1996. It is management's belief that the underlying obligations
will be met in the normal course of business without material adverse effect on
the Company's financial position.

         The Company is also obligated under rights-of-way and franchise
agreements with various entities for the use of their rights-of-way for the
installation of its telecommunications systems.

         Pursuant to an agreement with a joint venture, the Company is
obligated to invest up to $75,000 over the next two years in the form of
capital contributions and to pay $60,000 over the next four years to purchase
an indefeasible right of use for certain undersea capacity between the United
States and Europe that is being constructed by the joint venture. The Company
is also a party to the joint venture.

         In 1994, several former stockholders of MFS Telecom, a subsidiary of
the Company, filed a lawsuit against the Company, the Company's former majority
stockholder, KDG, and the Company's chief executive officer regarding the sale
of their shares of MFS Telecom to the Company in September 1992. The plaintiffs
alleged that certain information was concealed from them, which caused them to
sell their shares at an inadequate price. KDG agreed to indemnify the Company
against any claims asserted by the former stockholders. In July 1996 this
lawsuit was settled with no cost to the Company.

         The Company is also involved in various other claims and regulatory
proceedings incidental to its business. Management believes that any resulting
liability beyond that provided should not materially affect the Company's
financial position, results of operations or cash flows.

9.   INCOME TAXES:

         Loss before income taxes is comprised of a loss of approximately
$1,812,000, $251,000 and $139,000 from domestic operations and approximately
$26,000, $16,000 and $14,000 from foreign operations in 1996, 1995 and 1994,
respectively.

10.  STOCKHOLDERS' EQUITY:

         As discussed in Note 1 the Company's capital structure changed as of
the Merger to include only one share of common stock owned by WorldCom. Each
previously outstanding share of the Company's common stock was converted into
the right to receive 2.1 shares of common stock of WorldCom, and each share of
the Company's Series A and Series B Preferred Stock was converted into the
right to receive one share of WorldCom Series A and Series B Preferred Stock,
respectively. Following is a discussion of stockholders' equity prior to the
Merger.

10.  STOCKHOLDERS' EQUITY:--(CONTINUED)

(a)   Treasury Stock and Stock Split:

         In the first quarter of 1996, the Company retired the shares of common
stock that were held in treasury. The value of the treasury shares reduced
common stock, paid in capital and increased the accumulated deficit upon
retirement. In addition, the Company's stockholders approved an amendment to
the Company's restated certificate of incorporation to increase the number of
authorized shares of common stock to 400,000,000.

         On April 1, 1996, the Board of Directors declared a two-for-one common
stock split. The stock split was effected in the form of a stock dividend that
was payable to stockholders of record on April 16, 1996. The conversion
features of the Company's Series A and Series B preferred stock were adjusted
pursuant to their terms to maintain the proportionate rights of those preferred
stocks. In this report, all per share amounts and numbers of shares have been
restated to reflect the stock split. In addition, an amount equal to the $.01
par value of the shares outstanding at April 16, 1996 has been transferred from
additional paid-in capital to common stock.

(b)   Series A Preferred Stock:

         In May 1995, the Company issued 9,500,000 Depositary Shares (the
"Depositary Shares"), each representing a one one-hundredth interest in a share
of Series A 8% cumulative convertible preferred stock (the "Series A Preferred
Stock"), in a public offering. The proceeds of the offering, net of expenses,
was $306,455. The Depositary Shares were mandatorily convertible into an
aggregate of 19,000,000 shares of common stock. The Depositary Shares were also
redeemable at the option of the Company into shares of common stock on or after
May 31, 1998 at a ratio that would have varied depending upon certain factors,
including the market price of the common stock at the time of redemption and
the status of dividend payments. The Depositary Shares were also convertible at
the option of the holder at any time at a rate of 163.94 shares of common stock
for each share of Series A Preferred Stock (equivalent to a conversion price of
$20.43 per share of common stock), subject to certain adjustments.

         The Depositary Shares were entitled to receive dividends, when, as,
and if they are declared by the Board of Directors, accruing at the rate of
$2.68 per share per annum, payable quarterly in arrears on each February 28,
May 31, August 31 and November 30. Dividends were payable in cash or in shares
of common stock, at the election of the Company. Certain of the Company's debt
agreements restrict the Company's ability to pay cash dividends, and as a
result, the Company paid all dividends in common stock.

         The Depositary Shares were entitled to vote on the basis of .1000 of a
vote for each Depositary Share held (equivalent to 10 votes for each share of
Series A Preferred Stock). The Series A Preferred Stock had a liquidation
preference equal to the greater of (i) the sum of (a) $3,350 per share and (b)

10.  STOCKHOLDERS' EQUITY:--(CONTINUED)

(c)   Series B Preferred Stock:

         Pursuant to a planned restructuring of PKS' ownership in the Company's
capital stock, on September 30, 1995, the Company issued 15,000,000 shares of
Series B, 7 3/4% cumulative convertible preferred stock (the "Series B
Preferred Stock") to a wholly-owned subsidiary of PKS in exchange for 5,800,000
shares of the Company's common stock, which were retired. Also pursuant to that
restructuring, PKS purchased $1,000 of the Company's common stock and then
distributed all of its shares of the Company's common stock and the shares of
Series B Preferred Stock to certain of its stockholders. The Series B Preferred
Stock received by PKS' stockholders were subject to certain restrictions
regarding sale or transfer through September 30, 2001. The common stock
received and the Series B Preferred Stock issued in the exchange have been
accounted for based upon the market value of the common stock on September
30, 1995.

         The Series B Preferred Stock was convertible into shares of common
stock at any time after the first anniversary of the date of issuance at a
conversion price of $21.563 (an effective conversion rate of 0.0463768 shares
of common stock for each share of Series B Preferred Stock). Dividends on the
Series B Preferred Stock accrue at the rate of 7 3/4% per annum and were
payable in cash. Shares of Series B Preferred Stock were also redeemable at the
option of the Company at any time after September 30, 2001 at a redemption price
of $1.00 per share, plus accrued and unpaid dividends.

         Each share of Series B Preferred Stock had the right to ten votes on
all matters presented to the Company's stockholders, however the shares were
subject to an irrevocable proxy that had been granted to the Secretary and
Assistant Secretary of the Company on all matters other than the election of
directors and matters as to which holders of the Series B Preferred Stock voted
as a separate class. The proxy required the Secretary and Assistant Secretary
of the Company to vote all of the shares of Series B Preferred Stock in
proportion to the vote of the holders of the Company's common stock. The Series
B Preferred Stock had a liquidation preference over Junior Stock, as defined,
of $1.00 per share, plus an amount equal to unpaid dividends thereon, including
accrued dividends, whether or not declared.

(d)   Common Stock Warrants:

         The Company entered into an agreement on June 8, 1993 to issue
1,500,000 common stock warrants to an investment bank in consideration for the
provision of financial advisory services to the Company over a three-year
period. The warrants vested quarterly through June 7, 1996, and were
exercisable at $13.125 per share during the five-year period following the date
each portion vested and became exercisable. The fair value of the warrants as
of June 8, 1993 has been accounted for within stockholders' equity as
additional paid-in capital, with an offsetting deferred charge to equity and
was amortized over the three-year vesting period.

11.  EMPLOYEE BENEFIT PLANS:

         The Company had several stock-based and other compensation programs in
effect during 1996. The Company recognized compensation expense of $16,742
related to these programs in 1996. The programs are described as follows:

(a)   401(k) Plan:

         The Company administers a 401(k) Plan whereby eligible employees may
voluntarily contribute a percentage of compensation. The Company has not
contributed to the plan. Full-time employees who have attained 21 years of age
are eligible to participate.

(b)   Stock Option Plans:

         The Company's 1992 and 1993 Stock Plans, which were assumed by
WorldCom in the Merger, authorized among other things, the grant of options at
not less than 100% of the fair market value at the date of the option grant.
The Company registered 32,000,000 shares for the grant of options or other
awards under the two plans. The Compensation Committee of the Board of
Directors administered the stock plans. Options vest over a five-year period
and were generally exercisable up to five years after the grant was completely
vested.

         The Company utilized the fair value based accounting provisions of
SFAS 123 for 1996. For the Company's 1992 and 1993 Stock Plans, the fair value
was determined using option-pricing models that take into account the stock
price at the grant date, the exercise price, a five year expected life for the
options, an estimated volatility of 30% for the Company's stock price, no
expected dividends, and a risk-free interest rate of 6.21% over the expected
life of the options. The fair value of the options granted was estimated to be
$9.97 per option. Because the options granted in 1996 were predominantly issued
near the end of the year, the expense recognized was immaterial. Due to the
Merger, it is anticipated that the Company will conform with the accounting
principles of its parent, which utilizes the accounting provisions of
Accounting Principles Board Opinion No. 25 ("APB 25"), "Accounting for Stock
Issued to Employees," for all future periods. Under APB 25 it is anticipated
that no compensation expense will be recorded in the future related to these
plans.

         A summary of the changes in the Company's 1992 and 1993 Stock Plans
for the years ended December 31, 1996, 1995 and 1994, is presented below:

11.  EMPLOYEE BENEFIT PLANS:--(CONTINUED)

(b)   Stock Option Plans:--(continued)

         For the year ended December 31, 1995, the Company utilized the
accounting principles of APB 25 in accounting for its plans. Accordingly, no
compensation cost had been recognized for its stock option plans. Had
compensation costs for the Company's plans been determined based on the fair
value at the grant dates for awards under those plans consistent with the fair
value method of SFAS 123, the Company's net loss would have been $269,806 for
1995 and its loss per common share would have been $2.23. The fair value was
determined using option-pricing models that take into account the stock price
at the grant date, the exercise price, a five year expected life for the
options, an estimated volatility of 30% for the Company's stock price, no
expected dividend and a risk free interest rate that ranged from 5.38% to
7.88%.

(c)   Shareworks:

         In 1995 the Company implemented an employee benefit plan which is
comprised of a grant plan and a match plan jointly known as Shareworks. The
grant plan enables the Company to grant shares of the Company's common stock to
eligible employees based upon a percentage of the employee's eligible pay, up
to 5%. The original grant vests after three years with any additional grants
vesting immediately once the initial three year period has been met. The
Company granted approximately 100,000 and 128,000 shares of stock during
December of 1996 and 1995, respectively. The Company is recognizing
compensation expense based on the market value of the shares granted at the
grant date.

         The match plan allows eligible employees to defer between 1% and 10%
of eligible pay to purchase common stock of the Company at the stock price on
each pay period date. The Company matches the shares purchased by the employee
on a one-for-one basis. The stock, which is credited to each employee's account
to match the employee's purchase during any calendar quarter, vests three years
after the end of that quarter. The amount deferred by employees for purchases
of stock during 1996 and 1995 was $6,037 and $1,352, respectively. The Company
is recognizing compensation expense for the match shares over the vesting
period based on the market value of the shares at each pay period date.

(d)   Shareworks Plus:

         In 1996 the Company implemented a new employee stock compensation
program which grants stock awards with a four-year life and immediate vesting
to certain key executive employees under a program known as Shareworks Plus.
Under this program, the value received by the employee upon exercise of the
award is determined by the rate of increase in the Company's stock price
compared to the rate of increase in the S&P 500 index, measured from the grant
date. If the Company's common stock price performance is at or below the price
performance of the S&P 500 index, or under certain other circumstances defined
in the program, the value to be received by the employee upon exercise is $0.
If the Company's common stock price performance is above the price performance
of the S&P 500 index the value received by the employee upon exercise, which
would normally be paid in common stock of the Company, increases.

11.  EMPLOYEE BENEFIT PLANS:--(CONTINUED)

(d)  Shareworks Plus:--(continued)

         The Company utilizes the fair value based accounting provisions of
SFAS 123 for 1996. For the Company's Shareworks Plus program, the fair value
was determined using option-pricing models that take into account the stock
price at the grant date, the exercise price, a two year expected life for the
award, an estimated volatility of 30% for the Company's stock price, no
expected dividends, and a risk-free interest rate of 5.27% over the expected
life of the awards. The fair value of the awards granted was estimated to be
$6.50 per award. Due to the Merger, in the future the Company will conform with
the accounting principles of its parent which utilizes the accounting
provisions of APB 25.

         Under the Company's Shareworks Plus program, the Company granted
approximately 1,970,000 awards during 1996, at a weighted average exercise
price of $35.32. Approximately 609,000 awards were exercised during 1996 at a
weighted average exercise price of $31.92. As a result of the Merger, each
holder of an unexercised award is entitled to receive the value of each award
in cash in accordance with the award's original terms. Accordingly, the Company
recognized a liability of $120,867 and reduced paid-in capital at the end of
1996 to reflect this obligation.

(e)   UUNET Stock Option Plans:

         The Company adopted UUNET's existing stock option plans upon
acquisition, however, no further grants under these programs were made. Upon
the Merger these plans were assumed by WorldCom.

12.  ACQUISITIONS:

         Effective August 12, 1996, the Company purchased the common stock, and
options to purchase the common stock, of UUNET. UUNET is a provider of a
comprehensive range of Internet access services, applications, and consulting
services to businesses, professionals and on-line service providers. The total
cost of the acquisition was approximately $2,114,090, excluding transaction
costs and liabilities assumed. The Company issued approximately 58.2 million
shares of common stock and approved options to purchase approximately 6.2
million shares of the Company's common stock in the acquisition.

         The acquisition has been accounted for as a purchase and accordingly,
the acquired assets and liabilities have been recorded at their estimated fair
values at the date of the acquisition, and the results of operations have been
included in the accompanying consolidated financial statements since the date of
acquisition. The total purchase price in excess of the fair market value of the
net tangible assets acquired, identifiable intangibles, and in-process research
and development was recorded as goodwill. The value assigned to the in-process
research and development has been charged to expense in the statement of
operations.  The goodwill is being amortized on a straight-line basis over a
five year life.

12.  ACQUISITIONS:--(CONTINUED)

         The following unaudited pro forma information shows the results of the
Company as though the acquisition of UUNET occurred as of the beginning of each
period indicated. These results include certain adjustments consistent with the
Company's accounting policies related to amortization of intangible assets and
exclude the impact of non-recurring charges related to the acquisition such as
the write off of in-process research and development. These results are not
necessarily indicative of the results that actually would have been obtained if
the acquisition had been in effect at the beginning of each period or which may
be attained in the future.

12.  ACQUISITIONS:--(CONTINUED)

         These acquisitions have been accounted for as purchases and
accordingly, the acquired assets and liabilities were recorded at their
estimated fair values at the date of the acquisition, and the results of
operations have been included in the accompanying consolidated financial
statements since the dates of acquisition. The total purchase price in excess
of the fair market value of the net assets acquired was recorded as goodwill.
The goodwill is being amortized on a straight-line basis over a 40-year life.

         The following unaudited pro forma information shows the results of the

         In 1994, the Company recorded $24,514 of additional goodwill relating
to the settlement of a deferred purchase price adjustment that arose prior to
1994. In April 1990, the Company acquired 80% of the voting stock of Chicago
Fiber Optic Corporation, now doing business as Metropolitan Fiber Systems of
Chicago, Inc. ("MFS Chicago"). The acquisition was accounted for as a purchase.
A portion of the purchase price of the stock acquired was to be based upon the
fair market value of MFS Chicago in April 1993. During 1991, the Company
acquired an additional 10% of the voting stock of MFS Chicago for a deferred
purchase price based upon the MFS Chicago fair market value as of April 1993.
The deferred purchase price associated with these purchases of MFS Chicago
stock was assumed by KDG, the Company's majority stockholder at that time,
without recourse to the Company in 1993 and was settled in the first quarter of
1994. The Company recorded the settlement as goodwill and a capital
contribution by KDG.

         The Company also acquired the interest of certain minority
shareholders of its subsidiaries during 1995 and 1994.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING
         AND FINANCIAL DISCLOSURE

         On December 31, 1996, WorldCom acquired MFS pursuant to the merger
(the "Merger") of HIJ Corp., a wholly-owned subsidiary of WorldCom, with and
into MFS. Upon consummation of the Merger, MFS became a wholly-owned subsidiary
of WorldCom. The Merger was effected pursuant to an Amended and Restated
Agreement and Plan of Merger dated as of August 25, 1996, by and among
WorldCom, MFS and HIJ Corp.

         On January 20, 1997, MFS engaged Arthur Andersen LLP ("Arthur
Andersen") to perform the audit of the books and accounts of MFS and its
subsidiaries for fiscal year ended December 31, 1996. Prior to the Merger,
Arthur Andersen was the certifying accountant of WorldCom, which, for
accounting purposes, was the surviving corporation in the Merger. Coopers &
Lybrand L.L.P. ("Coopers & Lybrand") was dismissed pursuant to resolutions of
the Board of Directors as of January 20, 1997. Coopers & Lybrand's reports on
the financial statements of MFS for the fiscal years ended December 31, 1995
and 1994, did not contain an adverse opinion or a disclaimer of opinion, nor
were they qualified or modified as to uncertainty, audit scope, or accounting
principles.

         To the knowledge of management, during the fiscal years December 31,
1995 and 1994, and the subsequent period through the date of dismissal, there
were no disagreements with Coopers & Lybrand on any matter of accounting
principles, practices, financial statement disclosure, or auditing scope or
procedure which, if such agreement was not resolved to the satisfaction of
Coopers & Lybrand, would have caused it to make a reference to the subject
matter of such disagreements in connection with the report on the financial
statements.
