                WORLDPORT COMMUNICATIONS, INC. AND SUBSIDIARIES

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)



(1)      ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Organization and Basis of Presentation

         WorldPort Communications, Inc. (together with its subsidiaries, the
         "Company"), previously known as Sage Resources, Inc., was organized as
         a Colorado corporation on January 6, 1989, to evaluate, structure and
         complete mergers with, or acquisitions of other entities. In October
         1996, the Company changed its domicile to Delaware and changed to its
         current name. The Company is a rapidly growing facilities-based global
         telecommunications carrier offering voice, data and other
         telecommunications services to carriers, internet service providers
         ("ISPs"), medium and large corporations and distributors and
         resellers.

         The accompanying condensed consolidated financial statements have been
         prepared by the Company without audit pursuant to the rules and
         regulations of the Securities and Exchange Commission. Certain
         information and footnote disclosures normally included in financial
         statements prepared in accordance with generally accepted accounting
         principles have been condensed or omitted in this Form 10-Q pursuant
         to such rules and regulations; however, management believes that the
         disclosures herein are adequate to make the information presented not
         misleading. The financial statements and notes thereto included in
         this Form 10-Q should be read in conjunction with the financial
         statements and notes thereto included in the Company's Annual Report
         on Form 10-K for the year ended December 31, 1998.

         In the opinion of the Company's management, the accompanying condensed
         consolidated financial statements contain all adjustments necessary to
         present fairly the Company's financial position as of March 31, 1999,
         and the results of operations and cash flows for the three months
         ended March 31, 1999 and 1998. The results of operations for the three
         months ended March 31, 1999 are not necessarily indicative of the
         operating results for the full year.

         Financial Condition

         The Company is subject to various risks in connection with the
         operation of its business including, among other things, (i) an
         inability to repay the Interim Loan Facility due June 23, 1999, (ii)
         changes in external competitive market factors, (iii) termination of
         certain operating agreements or inability to enter into additional
         operating agreements, (iv) inability to satisfy anticipated working
         capital or other cash requirements, (v) changes in or developments
         under domestic or foreign laws, regulations, licensing requirements or
         telecommunications standards, (vi) changes in the availability of
         transmission facilities, (vii) changes in the Company's business
         strategy or an inability to execute its strategy due to unanticipated
         changes in the market, (viii) various competitive factors that may
         prevent the Company from competing successfully in the marketplace,
         and (ix) the Company's lack of liquidity and its ability to raise
         additional capital. The Company has incurred losses since inception,
         expects to continue to incur operating losses in the near future, and
         has an accumulated deficit of approximately $107.7 million as of March
         31, 1999 as well as a working capital deficit of approximately $132.3
         million. Funding of the Company's working capital deficit, current and
         future operating losses and expansion of the Company's global network
         will require substantial continuing capital investment. The Company's
         strategy is to fund these cash requirements through debt facilities
         and additional equity financing.

         The Company's Interim Loan facility, which matures on June 23, 1999,
         is secured by a lien on substantially all of the Company's assets and
         certain of its subsidiaries and a pledge of the capital stock of
         certain of the Company's subsidiaries. The Company is currently
         pursuing several alternative financing facilities for



                                       7
<PAGE>   8
         repaying the Interim Loan, but to date it does not have a repayment
         facility in place, nor any arrangement to extend the due date thereof.
         In the event that the Interim Loan is not repaid by its due date (or
         any extended maturity date as the case may be), the Interim Loan
         holders have an agreement with the Company and certain of the Company's
         stockholders (who held approximately 32% of the Company's outstanding
         votes as of April 30, 1999 and who include certain key members of
         management) pursuant to which the Company and such stockholders will be
         obligated to support and use their respective best efforts to achieve
         any transaction or series of transactions involving the sale of all or
         any part of the Company or any subsidiary or any of their assets which
         is proposed by the Interim Loan holders.

         Although the Company has been able to arrange debt facilities or
         equity financing to date, there can be no assurance that sufficient
         debt or equity financing will continue to be available in the future
         or that it will be available on terms acceptable to the Company.
         Failure to obtain sufficient capital could materially affect the
         Company's operations and expansion strategies. As a result of the
         aforementioned factors and related uncertainties, there is substantial
         doubt about the Company's ability to continue as a going concern.

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

         Loss per Share

         For all periods presented, basic and diluted earnings per share are
         the same as any dilutive securities had an antidilutive effect on
         earnings per share.

(2)      SEGMENT DISCLOSURES

         In June 1997, the FASB issued SFAS No. 131, "Disclosures about
         Segments of an Enterprise and Related Information". SFAS No. 131
         requires the reporting of profit and loss, specific revenue and
         expense items and assets for reportable segments. It also requires the
         reconciliation of total segment revenues, total segment profit or
         loss, total segment assets, and other amounts disclosed for segments
         to the corresponding amounts in the general purpose financial
         statements. The Company adopted SFAS No.
         131 during the year ended December 31, 1998.

         The Company views itself as participating in one business segment -
         facilities-based global telecommunications. Its operations can be
         viewed as European and North American. Intersegment revenues are not
         material. Financial data by geographic area for 1999 are as follows

(3)      COMMITMENTS AND CONTINGENCIES

         Interim Loan Facility

         To finance the EnerTel acquisition, the Company entered into a $120
         million Interim Loan facility with a consortium of lenders effective
         June 23, 1998, the terms of which also included the issuance of
         warrants. The Interim Loan, which matures on June 23, 1999, includes
         certain negative and affirmative covenants and is secured by a lien on
         substantially all of the assets of the Company and certain of its
         subsidiaries and a pledge of the capital stock of certain of the
         Company's subsidiaries. The Interim Loan bears interest at LIBOR (as
         defined in the credit agreement related to the Interim Loan) plus 6%
         per annum (13.125% at March 31, 1999) increasing by 0.5% per annum at
         the end of each period of three consecutive months after June 23,
         1998; provided, that such interest rate shall not exceed 16% per annum
         if paid in cash or 18% per annum if capitalized. As of March 31, 1999
         Interim Loan holders, in aggregate, have received warrants exercisable
         for 4,069,904 shares of common stock at a price per share of $0.01. In
         addition to the warrants which the Interim Loan holders had received
         as of March 31, 1999, such holders are entitled to receive additional
         warrants on the date the Interim Loan is repaid in full, so that all
         warrants issued to such holders represent 11% of the Company's
         fully-diluted outstanding Common Stock on the date of such repayment.
         As of March 31, 1999, the warrants were valued at an aggregate of
         $31.9 million and this amount is reflected as a reduction in the
         principal amount of the notes. This amount is being amortized to
         interest expense over the life of the loan (1 year).

         Capacity Commitments

         The Company has entered into agreements with a vendor for the purchase
         of STM-1's of capacity on the AC-1 cable system or STM-1 level
         capacity on additional undersea cable systems under development by
         this vendor. In 1998, the Company made a deposit of $2 million with
         this vendor which will be applied against the Company's aggregate $66
         million commitment over the next 3 years under this agreement. In
         March 1999, the Company purchased undersea cable capacity from the
         vendor by converting its deposit and paying an additional $4.6 million
         as down-payment, and obtaining vendor financing for the remaining
         $14.5 million purchase price. This vendor financing bears interest at
         a rate of 11.5% and requires quarterly principal payments of $1.2
         million commencing in June 1999 and ending in March 2002. The Company
         intends to sell a portion of this capacity to one or more customers by
         the end of the third quarter of 1999. Accordingly, the purchase cost
         of this capacity is classified as "Capacity held for resale" on the
         accompanying balance sheet.

         In February 1999, the Company entered into an agreement with a
         telecommunication carrier to sell to such carrier transmission
         capacity throughout various points of presence in Europe for
         approximately $8 million, payable upon acceptance of the circuits by
         the carrier. The contract provides the purchaser with an indefeasible
         right of use of this capacity for a period of 20 years. The Company
         has entered into a separate agreement with a European
         telecommunications company which gives the Company the right to
         purchase capacity through these points of presence. This contract
         provides for indefeasible right of use for a period of 10 years. The
         Company is pursuing means to satisfy the capacity commitment to the
         Company's customer for the remaining 10 years of that contract.

         Legal

         On May 14, 1999, the Company, John W. Dalton ("Dalton"), a former
         director of the Company and its former President and Chief Executive
         Officer, and the other parties entered into a negotiated settlement of
         all claims asserted in an arbitration proceeding initiated by the
         Company against Dalton. In that proceeding, the Company sought the
         rescission and cancellation of 1.2 million shares of its Common Stock
         that were issued to Dalton in connection with the Company's acquisition
         of a company formerly owned by Dalton. In the same proceeding, Dalton
         asserted a claim against the Company and others alleging among other
         things that those parties engaged in breach of contract, tortious
         interference and breach of fiduciary duty in connection with the
         termination of Dalton's employment contract. Under the settlement
         agreement, Dalton is required to return to the Company 500,000 shares
         of its Common Stock that were previously issued to him. Additionally, a
         $175,000 promissory note and 265,000 options claimed by Dalton were
         cancelled. All other claims of the parties were released.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
          CONDITION AND RESULTS OF OPERATIONS

NOTE ON "FORWARD-LOOKING" STATEMENTS

         The information set forth in Management's Discussion and Analysis of
         Financial Condition and Results of Operations ("MD&A") contains
         certain "forward-looking statements" within the meaning of Section 27A
         of the Securities Act of 1933, as amended, Section 21E of the
         Securities Exchange Act of 1934, as amended, and the Private
         Securities Litigation Reform Act of 1995, including, among others (i)
         expected changes in the Company's revenues and profitability (ii)
         prospective business opportunities and (iii) the Company's strategy
         for expanding and financing its business. Forward-looking statements
         are statements other than historical information or statements of
         current condition. Some forward-looking statements may be identified
         by use of terms such as "believes", "anticipates", "intends" or
         "expects". These forward-looking statements relate to the plans,
         objectives and expectations of the Company for future operations.
         Although the Company believes that its expectations with respect to
         the forward-looking statements are based upon reasonable assumptions
         within the bounds of its knowledge of its business and operations, in
         light of the risks and uncertainties inherent in all future
         projections, the inclusion of forward-looking statements in this
         report should not be regarded as a representation by the Company or
         any other person that the objectives or plans of the Company will be
         achieved.

         The Company's revenues and results of operations could differ
         materially from those projected in the forward-looking statements as a
         result of numerous factors, including, but not limited to, the
         following: (i) an inability to repay the Interim Loan Facility due
         June 23, 1999, (ii) changes in external competitive market factors,
         (iii) termination of certain operating agreements or inability to
         enter into additional operating agreements, (iv) inability to satisfy
         anticipated working capital or other cash requirements, (v) changes in
         or developments under domestic or foreign laws, regulations, licensing
         requirements or telecommunications standards, (vi) changes in the
         availability of transmission facilities, (vii) changes in the
         Company's business strategy or an inability to execute its strategy
         due to unanticipated changes in the market, (viii) various competitive
         factors that may prevent the Company from competing successfully in
         the marketplace, and (ix) the Company's lack of liquidity and its
         ability to raise additional capital. In light of these risks and
         uncertainties, there can be no assurance that actual results,
         performance or achievements of the Company will not differ materially
         from any future results, performance or achievements expressed or
         implied by such forward-looking statements. The foregoing review of
         important factors should not be construed as exhaustive. The Company
         undertakes no obligation to release publicly the results of any future
         revisions it may make to forward-looking statements to reflect events
         or circumstances after the date hereof or to reflect the occurrence of
         unanticipated events.

         The following discussion should be read in conjunction with the
         Condensed Consolidated Financial Statements and Notes thereto included
         under Item 1 of this Form 10-Q. In addition, reference should be made
         to the Financial Statements and Notes thereto and related Management's
         Discussion and Analysis of Financial Condition and Results of
         Operations included in the Company's Annual Report on Form 10-K for
         the year ended December 31, 1998.

OVERVIEW

         The Company is a rapidly growing facilities-based global
         telecommunications carrier offering voice, data and other
         telecommunications services to carriers, ISPs, medium and large
         corporations and distributors and resellers.

         The Company's growth to date has occurred principally through
         acquisitions, most notably its acquisition of EnerTel. The Company
         acquired EnerTel in June 1998, for consideration consisting of
         approximately $92 million and the payment of certain EnerTel
         indebtedness of approximately $17 million. In November 1998 the Company
         sold a 15% interest in the direct parent of EnerTel to former
         shareholders of EnerTel for approximately $14.8 million, of which
         approximately $2.8 million was an equity investment in the subsidiary
         and approximately $12 million was in the form of a shareholder note. 



                                      10
<PAGE>   11

         The principal on this shareholder note is payable ten years after the
         Company's repayment of the Interim Loan, which financed the Company's
         acquisition of EnerTel.

         In addition to the Company's EnerTel operations, during 1998 the
         Company acquired International InterConnect, Inc.("IIC") and
         Intercontinental Exchange, Inc. ("ICX") which serve distributors and
         resellers focused on international calling card and private line
         services. The Company believes that these operations help it to expand
         its name recognition and traffic volumes in emerging markets. Formerly
         based in the San Francisco Bay area, ICX provides telecommunication
         services principally through a network of agents and distributors in
         Japan and other Asian countries. During the first quarter of 1999,
         ICX's operations were integrated with the Company's Omaha, Nebraska
         based calling card operation and its traffic was migrated to the
         Company's Omaha switch. The Company acquired the assets and operations
         of ICX in April 1998, in exchange for 400,000 shares of Common Stock.

         In August 1998, the Company acquired the assets and operations of IIC.
         The purchase consideration was 879,442 shares of Common Stock and
         $750,000. Based in Rockledge, Florida, IIC specializes in providing
         international long distance services primarily in Latin America. IIC's
         customer base consists primarily of resellers, multinational
         corporations, foreign embassies, and other businesses.

         In February 1998, the Company commenced operations in the Netherlands
         through the acquisition of MathComp B.V., whose name was changed to
         WorldPort Communications Europe, B.V. ("WorldPort Europe"). In
         connection with this acquisition, the Company issued 150,000 shares of
         Common Stock and paid $250,000 in cash. The former shareholder of
         WorldPort Europe is eligible to earn an additional 2,350,000 shares of
         common stock contingent upon the attainment of certain future revenue
         and gross margin requirements during the first and second quarters of
         1999. Following the acquisition of EnerTel, the Company recorded
         charges of approximately $5.2 million in the fourth quarter of 1998
         for the wind down of the WorldPort Europe operations in 1999. See
         "Legal Proceedings."

         As of April 30, 1999, the Company had 22,744,979 shares of its Common
         Stock outstanding, or 54,282,701 shares on a fully diluted basis. The
         number of shares outstanding on a fully-diluted basis takes into
         account (i) all outstanding shares of Common Stock, (ii) all
         outstanding shares of the Company's convertible preferred stock,
         together with all options to acquire such stock and all shares of such
         stock which the Company has committed to issue, (iii) all outstanding
         warrants to acquire the Company's Common Stock, together with such
         number of additional warrants which the Company would have been
         required to issue to the Interim Loan holders had the Interim Loan been
         repaid on April 30, 1999 so that such holders would hold warrants
         exercisable into 11% of the fully-diluted outstanding Common Stock on
         such date (as contemplated by the Interim Loan facility), and (iv) all
         outstanding options which had vested as of April 30, 1999 and which had
         an exercise price at or below the market price on such date. The April
         30, 1999, 54,282,701 number of shares outstanding on a fully-diluted
         basis includes 3,077,032 shares related to an option held by an
         investor and due to expire upon repayment of the Interim Loan, 500,000
         shares recovered on May 14, 1999 as a result of the Dalton arbitration
         settlement (see "Legal Proceedings"), and 442,106 warrants which the
         Interim Loan holders would be entitled to receive as a result of the
         issuance of those shares.

         Capacity Commitments

         The Company has entered into agreements with a vendor for the purchase
         of STM-1's of capacity on the AC-1 cable system or STM-1 level
         capacity on additional undersea cable systems under development by
         this vendor. In 1998, the Company made a deposit of $2 million with
         this vendor which will be applied against the Company's aggregate $66
         million commitment over the next 3 years under this agreement. In
         March 1999, the Company purchased undersea cable capacity from the
         vendor by converting its deposit and paying an additional $4.6 million
         as down-payment, and obtaining vendor financing for the remaining
         $14.5 million purchase price. This vendor financing bears interest at
         a rate of 11.5% and requires quarterly principal payments of $1.2
         million commencing in June 1999 and ending in March 2002. The company
         intends to sell a portion of this capacity to one or more customers by
         the end of the third quarter of 1999. Accordingly, the purchase cost
         of this capacity is classified as "Capacity held for resale" on the
         accompanying balance sheet.

         In February 1999, the Company entered into an agreement with a
         telecommunication carrier to sell to such carrier transmission
         capacity throughout various points of presence in Europe for
         approximately $8 million,



                                      11
<PAGE>   12

         payable upon acceptance of the circuits by the carrier. The contract
         provides the purchaser with an indefeasible right of use of this
         capacity for a period of 20 years. The Company has entered into a
         separate agreement with a European telecommunications company which
         gives the Company the right to purchase capacity through these points
         of presence. This contract provides for indefeasible right of use for
         a period of 10 years. The Company is pursuing means to satisfy the
         capacity commitment to the Company's customer for the remaining 10
         years of that contract.

RESULTS OF OPERATIONS

         During the three months ended March 31, 1999, the Company incurred a
         loss of approximately $27 million compared to a loss of approximately
         $3 million during the same period in 1998. Included in the losses
         incurred during the three months ended March 31, 1999 are the
         operating results of EnerTel, IIC and ICX, including amortization of
         the purchased intangibles and recording of financing costs related to
         the Company's acquisition of EnerTel, as well as general expenses
         related to the Company's worldwide business development and financing
         activities. The operating results for ICX and IIC did not have a
         material impact on the losses incurred by the Company in 1999. To
         address and remedy historical operating losses and to increase its
         competitiveness, revenues and gross margins, the Company has taken
         various steps to improve each subsidiary's operating efficiency,
         network capability and carrier cost structure. The Company believes
         these cost-reduction and revenue-enhancing initiatives will have a
         positive impact on the Company's future operating results. However, as
         its business remains in the early growth stage, the Company
         anticipates that it will continue to incur operating losses and cash
         flow deficiencies for the near future.

         Revenues

         Revenues for the three months ended March 31, 1999 were $18.3 million
         compared to $948,000 for the three months ended March 31, 1998. The
         increase in revenues is primarily attributed to the inclusion of the
         results of operations of EnerTel, acquired in June 1998. EnerTel's
         revenues were $14.4 million during the three months ended March 31,
         1999. Also contributing to the increase over the prior year is the
         inclusion of ICX and IIC acquired in April and July 1998,
         respectively. Combined, these two entities contributed approximately
         $3 million in total revenues during the quarter ended March 31, 1999.

         EnerTel primarily generates revenue from the transmission of both
         domestic and international switched minutes in the Netherlands.
         EnerTel also derives revenues from the fixed monthly rental of private
         line circuits. The growth in EnerTel's revenues during 1998 and the
         first three months of 1999 included growth in all EnerTel product
         lines including virtual point of presence (VPOP) internet access;
         direct access local, national and international switched services; and
         800/900 products as well as the wholesale portion of the Bel 1600
         business, a residential services business which the Company sold in
         1998.

         Gross Margin

         Gross margin for the three months ended March 31, 1999 was $6.2
         million compared to $57,000 for the three months ended March 31, 1998.
         The increase in gross margin was primarily due to the inclusion of the
         results of operations of EnerTel, ICX and IIC. The Company's primary
         costs of sales are its cost of terminating switched minutes through
         third parties, as well as its cost to access circuits used to connect
         its customers in the Netherlands.

         Selling, General and Administrative Expenses

         Selling, general and administrative expenses increased to $12.6
         million from $2.3 million for the three months ended March 31, 1999
         and 1998, respectively. The increase is primarily due to (i) the
         inclusion of the selling, general and administrative expenses
         associated with the operation of EnerTel, IIC and ICX, (ii) increased
         business development and expansion activity, and (iii) growth in the
         Company's U.S.
         operations, marketing and corporate staff.

         Depreciation and Amortization

         Depreciation and amortization expense for the three months ended March
         31, 1999 was $5.3 million compared to $631,000 for the three months
         ended March 31, 1998. The increase was due to (i) depreciation on the
         assets acquired in connection with the EnerTel, IIC and ICX
         acquisitions, (ii) amortization of goodwill and other intangible
         assets associated with the EnerTel, IIC and ICX acquisitions, and
         (iii) depreciation on additional switching and network equipment
         acquired during 1998 and 1999.

         Other Income (Expense)

         Interest expense, net increased to $15.6 million from $176,000 for the
         three months ended March 31, 1999 and 1998, respectively. The increase
         in interest expense is due primarily to the Interim Loan, which
         accounted for $15 million of interest expense during the three months
         ended March 31, 1999. Interest expense also included interest for (i)
         the debt the Company assumed in connection with the EnerTel and IIC
         acquisitions, and (ii) the acquisition of switching equipment subject
         to capital lease.

         Other expense, net for the three months ended March 31, 1999 was
         $880,000 compared to $0 for the three months ended March 31, 1998.
         This amount represents the costs incurred to exit certain commitments
         and relationships which are no longer considered in line with the
         Company's core strategy.

LIQUIDITY AND CAPITAL RESOURCES 

         The Company is an emerging international telecommunications service
         provider executing a global business plan that requires substantial
         capital. The Company currently has a working capital deficit and has
         operated at a loss since its inception. Funding of the working capital
         deficit, current and future operating losses, expansion of the
         Company's global network, and repayment of the Interim Loan facility
         will require substantial continuing capital investment.

         As of March 31, 1999 and December 31, 1998 the Company had a working
         capital deficit of $132.3 million and $103.8 million respectively. The
         working capital deficit at March 31, 1999 is due to (i) the Interim
         Loan, (ii) the assumption of certain liabilities assumed in
         conjunction with the Enertel, IIC and ICX acquisitions, the majority
         of which were trade payables and short-term debt obligations, (iii)
         the acquisition of additional switching and peripheral equipment and
         transatlantic capacity, the majority of which is being financed
         pursuant to capital leases and vendor financing, and (iv) the
         operating losses of the Company. Trade receivables increased to $13.5
         million at March 31, 1999 from $11.8 million at December 31, 1998
         largely due to increases in customer revenue.

         Operations used $17.6 million during the three months ended March 31,
         1999 due primarily to the (i) operating losses, and (ii) increased
         business development and expansion activity.

         Investing activities used $8 million during the three months ended
         March 31, 1999. Investing activities during the three months ended
         March 31, 1999 consisted entirely of capital spending.

         Financing activities provided $31 million during the three months
         ended March 31, 1999. Financing activities during the three months
         ended March 31, 1999 consisted primarily of proceeds from the issuance



                                      13
<PAGE>   14

         of 920,419 shares of the Series C convertible preferred stock and the
         exercise of employee stock options, reduced by principal payments on
         capital leases and notes payable.

         To finance the EnerTel acquisition, the Company entered into a $120
         million Interim Loan facility with a consortium of lenders effective
         June 23, 1998, the terms of which also included the issuance of
         warrants. The Interim Loan, which matures on June 23, 1999, includes
         certain negative and affirmative covenants and is secured by a lien on
         substantially all of the assets of the Company and certain of its
         subsidiaries and a pledge of the capital stock of certain of the
         Company's subsidiaries. The Interim Loan bears interest at LIBOR (as
         defined in the credit agreement related to the Interim Loan) plus 6%
         per annum increasing by 0.5% per annum at the end of each period of
         three consecutive months after June 23, 1998; provided, that such
         interest rate shall not exceed 16% per annum if paid in cash or 18%
         per annum if capitalized. As of March 31, 1999 Interim Loan holders,
         in aggregate, have received warrants exercisable for 4,069,904 shares
         of common stock at a price per share of $0.01. In addition to the
         warrants which the Interim Loan holders had received as of March 31,
         1999, such holders are entitled to receive additional warrants on the
         date the Interim Loan is repaid in full, so that all warrants issued
         to such holders represent 11% of the Company's fully-diluted
         outstanding Common Stock on the date of such repayment. As of March
         31, 1999, the warrants were valued at an aggregate of $31.9 million
         and this amount is reflected as a reduction in the principal amount of
         the notes. This amount is being amortized to interest expense over the
         life of the loan (1 year).

         Funding of the Company's working capital deficit, current and future
         operating losses and execution of its global growth plans will require
         substantial continuing capital investment. The Company's strategy is
         to fund these cash requirements through debt facilities and additional
         equity financing. In addition, the Company currently has approximately
         $41 million in equipment lease facilities.

         The Company's Interim Loan facility, which matures on June 23, 1999, is
         secured by a lien on substantially all of the Company's assets and
         certain of its subsidiaries and a pledge of the capital stock of
         certain of the Company's subsidiaries. The Company is currently
         pursuing several alternative financing facilities for repaying the
         Interim Loan, but to date it does not have a repayment facility in
         place, nor any arrangement to extend the due date thereof. In the event
         that the Interim Loan is not repaid by its due date (or any extended
         maturity date as the case may be), the Interim Loan holders have an
         agreement with the Company and certain of the Company's stockholders
         (who held approximately 32% of the Company's outstanding votes as of
         April 30, 1999 and who include certain key members of management
         pursuant to which the Company and such stockholders will be obligated
         to support and use their respective best efforts to achieve any
         transaction or series of transactions involving the sale of all or any
         part of the Company or any subsidiary or any of their assets which is
         proposed by the Interim Loan holders.

         Although the Company has been able to arrange debt facilities or
         equity financing to date, there can be no assurance that sufficient
         debt or equity financing will continue to be available in the future
         or that it will be available on terms acceptable to the Company.
         Failure to obtain sufficient capital could materially affect the
         Company's operations and expansion strategies. As a result of the
         aforementioned factors and related uncertainties, there is substantial
         doubt about the Company's ability to continue as a going concern.

YEAR 2000 ISSUE

         The efficient operation of the Company's business is dependent in part
         on computer software programs and operating systems. These programs
         and systems are used in network trafficking, call origination and
         termination, pricing, sales, billing and financial reporting, as well
         as various administrative functions. Recognizing the importance and
         need for an integrated information systems solution, the Company has
         developed an implementation plan for upgrading its systems
         architecture. This plan also addresses the functionality of its
         systems beyond December 31, 1999 ("Year 2000 compliance"). Typically
         the Company's upgrades made for additional functionality also remedy
         any Year 2000 deficiencies in the related software. However, the
         Company does not consider the cost of such upgrades to be year 2000



                                      14
<PAGE>   15

         related, as it has not accelerated any upgrades to remedy a Year 2000
         deficiency.

         The Company does not anticipate additional material expenditures for
         Year 2000 compliance issues. As WorldPort is a relatively new company,
         commencing operations in late 1997, Year 2000 compliance has been a
         requirement in all system related procurement. In circumstances where
         acquired subsidiaries' systems are not compliant, remediation via
         upgrades or system change-out is on-going. The Company's new systems
         implementation is expected to be completed by September 30, 1999.
         Management believes that the Company's remaining information
         technology ("IT") systems and other non IT systems are either Year
         2000 compliant or will be compliant by September 30, 1999 after
         applying vendor supplied upgrades to these systems. The cost of the
         upgrades are not considered to be material.

         The Company is in the process of obtaining documentation from its
         suppliers, customers, financial institutions and others as to the
         status of their Year 2000 compliance programs and the possibility of
         any interface difficulties relating to Year 2000 compliance that may
         affect the Company. While few significant concerns were identified,
         each has been addressed with a program of remediation. All programs
         are targeted for completion by September 1, 1999. However, Year
         2000-related operating problems or expenses may arise in connection
         with the Company's computer systems and software or in connection with
         the Company's interface with the computer systems and software of its
         suppliers, customers, financial institutions and others. Because such
         third-party systems or software may not be Year 2000 compliant, the
         Company is in the process of developing contingency plans to address
         Year 2000 failures of the entities with which it interfaces. The
         Company could be required to incur unanticipated expenses to remedy
         any problems, which could have a material adverse effect on its
         business, results of operation and financial conditions.

         The Company's worst case scenario does not contemplate a major
         business disruption from internal systems. The Company believes that
         it has exercised reasonable diligence to assess whether external
         systems and interfaces are adequately prepared.

NEW ACCOUNTING PRONOUNCEMENTS

         In June 1998, the FASB issued Statement of Financial Accounting
         Standards No. 133, Accounting for Derivative Instruments and Hedging
         Activities, which is effective for fiscal years beginning after June
         15, 1999. SFAS No. 133 establishes accounting and reporting standards
         for derivative instruments and transactions involving hedge
         accounting. The Company has not yet determined the impact this
         statement will have on its consolidated financial statements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company believes that its exposure to market rate fluctuations on
         its investments is nominal due to the short-term nature of those
         investments. To the extent the Interim Loan is outstanding, the
         Company has market risk relating to such amounts because the interest
         rates under the Interim Loan are variable. The Company does not
         believe its exposure represents a material risk to the financial
         statements.

         WorldPort's operations in Europe, principally in the Netherlands,
         expose the Company to currency exchange rates risks. To manage the
         volatility attributable to these exposures, the Company nets the
         exposures to take advantage of natural offsets. Currently, the Company
         does not enter into any hedging arrangements to reduce this exposure.
         The Company is not aware of any facts or circumstances that would
         significantly impact such exposures in the near-term. If, however,
         there was a 10 percent sustained decline of the Dutch Gilder versus
         the U.S. dollar, then the consolidated financial statements could be
         materially effected as our Dutch operations represented approximately
         69% of our total assets as of March 31, 1999 and 79% and 73% of our
         total revenues and net loss for the three months ended March 31, 1999,
         respectively.

                           PART II. OTHER INFORMATION


ITEM 1.  LEGAL PROCEEDINGS

         On April 17, 1998, the Company was served with a summons and complaint
         from MC Liquidating Corporation f/k/a MIDCOM Communications, Inc.
         ("MIDCOM"). Both the Company and TNC, its wholly-owned subsidiary are
         named as defendants, as are Telenational Communications, Limited
         Partnership, the former owner of the TNC assets ("TCLP"), and Edmund
         Blankenau, a principal of TCLP and one of the Company's former
         directors. In its complaint, filed on April 8, 1998 in the U.S.
         Bankruptcy Court for the Eastern District of Michigan, Southern
         Division, MIDCOM seeks payment of over $600,000 for services allegedly
         provided to TCLP and the Company, together with other damages,
         attorney fees and costs. The parties are currently engaging in
         discovery. The Company believes the claims are without merit and
         intends to vigorously defend against them.

         The Company and WorldPort Communications Europe, B.V., one of the
         Company's European subsidiaries ("WorldPort Europe"), are defendants
         in litigation filed in the Sub-District and District courts of The
         Hague, located in Rotterdam, Netherlands. The cases, filed in January,
         1999, by Mr. Bahman Zolfagharpour, allege that the Company breached
         agreements with Mr. Zolfagharpour in connection with its purchase of
         MathComp B.V. (now WorldPort Europe) from Mr. Zolfagharpour and its
         subsequent purchase of EnerTel. The litigation seeks damages in an
         amount exceeding $20 million and the award of 2,500,000 shares of the
         Company's common stock to Mr. Zolfagharpour. The Company believes that
         the litigation is wholly without merit and intends to defend the case
         vigorously. Earlier claims filed by Mr. Zolfagharpour with respect to
         his employment agreement with WorldPort Europe have been resolved.

         On May 14, 1999, the Company, John W. Dalton ("Dalton"), a former
         director of the Company and its former President and Chief Executive
         Officer, and the other parties entered into a negotiated settlement of
         all claims asserted in an arbitration proceeding initiated by the
         Company against Dalton. In that proceeding, the Company sought the
         rescission and cancellation of 1.2 million shares of its Common Stock
         that were issued to Dalton in connection with the Company's acquisition
         of a company formerly owned by Dalton. In the same proceeding, Dalton
         asserted a claim against the Company and others alleging among other
         things that those parties engaged in breach of contract, tortious
         interference and breach of fiduciary duty in connection with the
         termination of Dalton's employment contract. Under the settlement
         agreement, Dalton is required to return to the Company 500,000 shares
         of its Common Stock that were previously issued to him. Additionally, a
         $175,000 promissory note and 265,000 options claimed by Dalton were
         cancelled. All other claims of the parties were released.

         From time to time, the Company is involved in various other lawsuits
         or claims arising from the normal course of business. In the opinion
         of management, none of these lawsuits or claims will have a material
         adverse effect on the Company's financial condition or results of
         operations.

ITEM 2.  CHANGES IN SECURITIES

         In the first quarter of 1999, the Company made the following issuances
         of securities without registration under the Securities Exchange Act
         of 1934, as amended ("Securities Act"). All such issuances were made
         to "accredited investors" as defined in the Securities Act and its
         regulations and were exempt from registration under Section 4(2) of
         the Securities Act:

         In December 1998, the Company entered into a Series C Preferred Stock
         Purchase Agreement (the "Purchase Agreement") with an investor,
         pursuant to which the investor acquired 1,132,824 shares of Series C
         for an aggregate purchase price of $40 million ($32.5 million was
         received for 920,419 shares in January 1999). Pursuant to the Purchase
         Agreement, the investor also received an option to acquire up to
         283,206 shares of Series C Preferred Stock for an aggregate purchase
         price of $10 million. This option



                                      16
<PAGE>   17

         expires upon the repayment or refinancing of the Interim Loan.

         During the quarter, various holders of Series B Preferred Stock
         converted their shares into 3.1 million shares of the Company's Common
         Stock in accordance with the terms of the Series B Preferred Stock.

rights or licenses in respect of any intellectual property of the other.

liable to the other (except for the payment of charges due or provision of other

of its obligations under the Agreement to the extent that such delay or
non-performance is due to Force Majeure of which it has notified the other

its obligations under this Agreement, either Party shall be entitled to
terminate this Agreement by giving not less than fourteen (14) days written
notice to the other immediately upon the expiry of the 30-day period, provided

                             SERVICE LEVEL AGREEMENT

         The purpose of this Service Level Agreement ("SLA") is to establish the
procedures for installation and acceptance of the Services as well as for
preventative and corrective maintenance.

         Definitions

         "EMERGENCY OUTAGE" means an outage that is not planned or for which the
Parties do not have prior advanced notice and which requires the suspension of
or disruption to the Services in order to restore the Services.

         "WORLDPORT HELP DESK" means the Help Desk operated twenty-four (24)
hours a day every day during the Service Period by WORLDPORT.

         "FAULT CLEARANCE PROCEDURES" means the procedures for operation and
maintenance of the Services (as specified hereunder) provided by WORLDPORT in
co-operation with STAR in order to correct Service Affecting and Non-Service
Affecting Faults ("Fault Repair").

         "NETWORK CONTROL CENTRE" means the service centre operated by WORLDPORT
in order to control, maintain and configure the WORLDPORT Network.

         "NON SERVICE AFFECTING FAULT" means any failure, interruption or
disruption of the SDH Network, which does not affect normal traffic transmission
over such network.

         "PLANNED OUTAGE" means suspension of or disruption to the Services, the
occurrence of which has been agreed in advance by the Parties or of which the
Parties have prior advance notice.

         "SERVICE AFFECTING FAULT" means any failure, interruption or disruption
of the SDH Network, which materially affects normal traffic transmission over
such network.

         "SERVICE AVAILABILITY" means the period of time in which the Services
are available for use by STAR in comparison to the period of time in which the
Services are not so available.

         "SERVICE CREDITS" means such credit serving as compensation to STAR in
the event that the targeted service availability levels (as specified hereunder)
are not met by WORLDPORT.

         Installation and Acceptance Procedures

         Prior to the provision of the Services, WORLDPORT and STAR shall agree
upon an installation plan specifying the required responsibilities, procedures,
acceptance criteria and timetables.

         Following completion of acceptance testing, WORLDPORT will supply STAR
with the test results. Thereafter, STAR will have 5 days in order to conduct its
own acceptance testing.



<PAGE>   13

         Unless STAR notifies WORLDPORT that the Services do not comply with
specifications, the expiry of the 5-day period marks the date of acceptance by
STAR of the test results, which, in turn, marks the Commercial Operations Date.

         Service Availability and Performance Levels

         WORLDPORT will use best endeavors to provide the Services at a service
availability level of at least 99.95%.

         Service Credits

         Without prejudice to Section 8 and Section 9 of this Service Level
Agreement, WORLDPORT shall provide STAR with Service Credits (as specified
below) in the event that the stipulated availability level is not met where such
does not result from the failure of STAR to comply with the terms and conditions
of this Agreement or from any Service Variations as defined under Annex I to the
Agreement.

         A.        (b).  Availability Measurements

Availability is calculated on a monthly basis as follows:

            (Total time - Sum of all events of unavailable time as agreed during
fault clearance) * 100

         Total time.

         Performance Reports

         Performance reports will be provided to STAR on a monthly basis. These
will include a log of any faults, reported by STAR, or detected at the Network
Control Centre, giving details of the progress and timing of any fault clearance
activity.

         Fault Reporting


                                       2
<PAGE>   14

         STAR shall report faults by contacting by telephone the WORLDPORT Help
Desk at the telephone numbers set forth below ("Fault Reports").

         Upon receipt of the Fault Report, WORLDPORT will allocate a job ticket
number and a priority level to the fault.

         The Parties shall reference the job ticket number in all communications
that relate to the Fault Report.

         The Priority Level will characterize the fault as either a Service
Affecting or Non-Service Affecting Fault which will determine the Fault
Clearance Procedures to be taken.

         Non-Service Affecting Fault Clearance Procedures

         If a Non-Service Affecting Fault is detected by the Network Control
Centre the Services will be automatically switched to an alternative route.

         WORLDPORT will only notify STAR of Non-Service Affecting Faults in the
monthly reporting procedure.

         Service Affecting Fault Clearance Procedures

         WORLDPORT shall use best endeavors to clear Service-Affecting Faults
within 4 hours of receiving Fault Report from STAR or detection of the Fault by
the Network Control Centre.

         In the event of a Service-Affecting Fault, WORLDPORT shall keep STAR
informed of fault clearance activity and shall promptly notify STAR when the
fault(s) has/have been cleared.

         If Service-Affecting Faults are not cleared within 4 hours, fault
clearance activities will be escalated through the WORLDPORT management
structure to the Director of Networks.

         Planned Outage

         From time-to-time there will be a need to undertake planned work on the
WORLDPORT Network, in order to perform preventive maintenance, or to increase
network capacity and/or coverage. Planned outages will be carried out in
maintenance windows which will be notified to STAR 28 days in advance. If such
planned work is of a nature that is likely to be Service-Affecting, WORLDPORT
shall provide STAR with as much advanced notice as is reasonable under the
circumstance, with such notice normally being not less than 28 days prior to the
commencement of the planned works. In such an event, STAR shall provide
WORLDPORT all necessary assistance and co-operation in order to complete the
planned works efficiently. For the avoidance of doubt, no Service Credits or
claim to damages may be made by STAR for Planned Outages except where there is a
loss of Services.

EMERGENCY OUTAGE

         In the event of an Emergency Outage, WORLDPORT shall provide STAR with
such notice (as may be deemed reasonable under the circumstances), indicating
the nature of the



                                       3
<PAGE>   15

outage and its expected duration. In return, STAR shall provide WORLDPORT with
such assistance and co-operation as may be necessary for the restoration of the
Services. For the avoidance of doubt, no Service Credits or claim to damages may
be made by STAR for loss of Services due to Emergency Outages that result from a
Force Majeure event. In all cases, however, when WorldPort receives a credit
from its underlying capacity supplier, WorldPort will, as a minimum, pass any
such credit on to STAR on a proportional basis.

                             SERVICE ORDER PROCEDURE

         Placing an Order

         STAR shall place a service order by using the WORLDPORT Service Order
Form designed for the managed bandwidth services.

         WORLDPORT will acknowledge receipt of the service order within one
working day.

         On receipt of the service order, WORLDPORT will verify the service
requested, determine whether the requested service delivery date is feasible
taking into account, among others, the status of the required POPs on the
relevant RING(s), and confirm or review the date with STAR within one week

CONFIRMING AN ORDER

         Upon completion of verification procedures by WORLDPORT, the Parties
shall then sign the Service Order Form. In order for the service order to remain
valid, the Parties shall sign it within one month of agreement of the service
delivery date or at the date at which the relevant PoPs are "live" and available
whichever is the earliest.

         If the Service Order details (including Start date) cannot be verified
within one week of order receipt, then WORLDPORT will keep STAR informed of
progress on a weekly basis during verification.

claims, execute such documents and do whatever else may be reasonably necessary
to enable the other party to pursue any such action against such third party.

16.      CONFIDENTIALITY

         16.1     Information. Worldport and STAR hereby agree that if either
party provides confidential or proprietary information to the other party
("Proprietary Information"),



                                       11
<PAGE>   28

such Proprietary Information shall be held in confidence, and the receiving
party shall afford such Proprietary Information the same care and protection as
it affords generally to its own confidential and proprietary information (which
in any case shall be not less than reasonable care) in order to avoid disclosure
to or unauthorized use by any third party. This Agreement, including all of the
terms, conditions and provisions hereof, constitutes Proprietary Information,
and all information disclosed by either party to the other in connection with or
pursuant to this Agreement shall be deemed to be Proprietary Information,
provided that written information is clearly marked in a conspicuous place as
confidential or proprietary, and verbal information is indicated as being
confidential or proprietary when given or promptly confirmed in writing as such
thereafter. All Proprietary Information, unless otherwise specified in writing,
shall remain the property of the disclosing party, shall be used by the
receiving party only for the intended purpose, and such written Proprietary
Information, including all copies thereof, shall be returned to the disclosing
party or destroyed after the receiving party's need for it has expired or upon
the request of the disclosing party. Proprietary Information shall not be
reproduced except to the extent necessary to accomplish the purposes and intent
of this Agreement, or as otherwise may be permitted in writing by the disclosing
party.

         16.2     Exceptions. The foregoing provisions of Section 16.1 of this
Addendum shall not apply to any Proprietary Information which (i) becomes
publicly available other than through the recipient; (ii) is required to be
disclosed by a governmental or judicial law, order, rule or regulation; (iii) is
independently developed by the disclosing party; or (iv) becomes available to
the disclosing party without restriction from a third party. If any Proprietary
Information is required to be disclosed pursuant to the foregoing clause (ii),
the party required to make such disclosure shall promptly inform the other party
of the requirements of such disclosure.

         16.3     Disclosure. Notwithstanding Sections 16.1 and 16.2 of this
Addendum, either party may disclose Proprietary Information to its employees,
agents, and legal, financial, and accounting advisors and providers (including
its lenders and other financiers) to the extent necessary or appropriate in
connection with the negotiation and/or performance of this Agreement or its
obtaining of financing, provided that each such party is notified of the
confidential and proprietary nature of such Proprietary Information and is
subject to or agrees to be bound by similar restrictions on its use and
disclosure.

         16.4     Survival. The provisions of this Section 16 shall survive
expiration or termination of this Agreement.

17.      DEFAULT

         17.1     Notice. A party shall be in default under this Agreement
thirty (30) days after the non-defaulting party shall have given written notice
of such default unless the defaulting party shall have cured such default or
such default is otherwise waived by the non-defaulting party within such thirty
(30) days; provided, however, that where any such default other than the payment
of money cannot reasonably be cured within such 30-day period, if the defaulting
party shall proceed promptly to cure the same and prosecute such cure with due
diligence, the time for curing such default shall be extended for such period of
time not to exceed ninety (90) days as may be necessary to complete such cure.
If STAR assigns any of its rights under this Agreement



                                       12
<PAGE>   29

to its lender as collateral security, and at the time of such assignment or
thereafter Worldport receives written notice of such assignment, co-signed by
both such lender and by STAR, Worldport agrees that any written notice of
default by Worldport delivered to STAR under this Section shall be accompanied
by a copy of such notice being delivered simultaneously to such lender, and that
such lender shall have the right to cure any such default on the same basis that
STAR would have the right to cure such default hereunder.

         17.2     Remedies. Upon failure to make any payment or other default by
a party, after notice thereof and the above opportunity to cure, the
non-defaulting party may (i) take such action as it determines, in its sole
discretion, to be necessary to correct the default, and/or (ii) pursue any
remedies it may have under applicable law or principles of equity relating to
such default. Notwithstanding the above, if the defaulting party certifies in
good faith to the non-defaulting party in writing that a default has been cured,
such default shall be deemed to be cured unless the non-defaulting party
otherwise notifies the defaulting party in writing within fifteen (15) days of
receipt of such notice.

18.      TERMINATION

         18.1     Mutuality. Either party may terminate this Agreement upon the
failure of the other party to cure an event of default as required by Section 17
of this Addendum.

         18.2     Existing Defaults. Notwithstanding the foregoing, no
termination or expiration of this Agreement shall affect the rights or
obligations of any party hereto with respect to any then existing defaults or
the obligation to make any payment hereunder for services rendered prior to the
date of termination or expiration.

         18.3     Non-cancellable IRUs. Notwithstanding any other provision of
this Agreement, there shall be no termination or cancellation of any IRU for any
Capacity for which the entire Purchase Price has been paid..

                    AND PROTECTION AND RESTORATION STANDARDS


Capacity Specifications and Acceptance Testing

System Performance Standards and Specifications. Worldport at all times will
         ensure that the Worldport Network meets or exceeds the following System
         Performance Standards and Specifications:

         A.       SYSTEM DESCRIPTIONS FOR OC-3/STM-1 FOLLOW:

                  GENERAL DESCRIPTION: The requirements in this Agreement were
developed to establish a practical OC-3/STM-1 interface. Compliance with these
specifications should provide a satisfactory OC interface in a high percentage
of installations. Worldport will allow and encourage STAR's and its Affiliates'
participation to ensure an orderly, functional and mutually trouble-free
interface at all locations. This Technical Reference ("TR") describes physical,
protocol and performance requirements at the Point of Interface ("POI")
necessary for compatible operation between the Worldport and the STAR and its
Affiliates' Installation. Specifically, this TR describes the OC-3/STM-1 optical
interfaces offered by Worldport. The POI specifications have been established
based upon Industry Standards developed by the American National Standards
Institute (ANSI) and Bellcore. This TR articulates Worldport's interpretation of
these standards and provides clarification of interface requirements as
necessary.

                  OC-3/STM-1: The ANSI SONET (Synchronous Optical Network)
transmission standard for high capacity optical telecommunications, whose line
rate is 155.52 Mbps. One OC-3 is comprised of 3 STS-1 Synchronous Transport
Signal Level 1 signals whose transport overheads are frame aligned, but whose
associated Synchronous payload envelopes are not necessarily aligned. Each
STS-1, at 51.84 Mbps represents the lowest level SONET signal. The STS-1 is
defined at the electrical level prior to optical conversion. These SONET
standards and elements are further defined in the "Bellcore Synchronous Optical
Network (SONET) Transport Systems: Common Generic Criteria GR-253-CORE, Issue 2,
December, 1995."

                  SONET SIGNAL FORMAT: The signal format at the SONET interface
is based on the SONET frame structure as specified in Bellcore GR-253-CORE,
Synchronous Optical Network (SONET) Transport Systems: Common Criteria Physical
Layer, and ANSI T1.105, Digital Hierarchy B Optical Interface Rates and Formats
Specifications (SONET).

         B.       TECHNICAL SPECIFICATIONS

1.       INTERCONNECT SPECIFICATIONS:

                  1.1      The STAR's and its Affiliates' interconnection point
                  of DS-1 & DS-3 signals at the Worldport (SPT) location will be
                  at an industry standard (DSX-1) &



                                       17

                  (DSX-3) digital cross-connect panels and will be referred to
                  as the Worldport Network Interface in this document.

                  1.2      The DS-1 & DS-3 signals terminating at the Worldport
                  digital cross-connect panels will meet the electrical
                  specifications as defined in AT&T Compatibility Bulletin (CB)
                  No. 119, Issue 3, October, 1979.

                  1.3      The Worldport Digital Network will be compatible with
                  the Bell System hierarchical clock synchronization methods and
                  stratum levels as described in Bellcore Technical Advisory
                  (GR436-Core).

                  1.4      STAR's or its Affiliates' equipment must also meet
                  the interconnect specifications listed above and shall comply
                  with jitter requirements of AT&T Technical Reference PUB
                  63411.

1.       Performance Objectives:

                  2.1      DS1, DS3, and OC-3/STM-1 circuit performance will be
                  measured using two parameters: Availability and Error-Free
                  Seconds.

                  The following assumptions apply to the derived data:

                           The circuits originate and terminate on the Worldport
                           backbone
                           High speed protection switching:  1 for N, where N=2
                           MTTR for SONET equipment:  2 hours
                           MTTR for fiber optic cable:  12 hours (Bellcore
                           Standard)
                           Cable cut rate:  4.39 /year/1,000 sheath miles
                           (Bellcore Standard)

                  2.2      Availability is a measure of the relative amount of
                  time during which the circuit is available for use. According
                  to CCITT and ANSI definitions, unavailability begins when the
                  Bit Error Ratio (BER) in each second is worse than 1.0 E-3 for
                  a period of 10 consecutive seconds.

                  INTER OFFICE CHANNEL (IOC) : An Inter Office Channel refers to
                  the Worldport Communications network between the points of
                  presence (POP).

                  OPTICAL CARRIER LEVEL 1 (OC-1) : The optical signal that
                  results from an optical conversion of an electrical STS-1
                  signal (51.840 Mb/s). This signal forms the basis of the
                  interface.

                           OC-3/STM-1: Optical Carrier level 3 signal operating
                  at 155.520 Mb/s.

                                    POINT OF PRESENCE (POP) : A physical
                  location where a long distance carrier terminates lines before
                  connecting to the local exchange carrier, another carrier, or
                  directly to a customer.

                  2.3      The availability objective for all circuits between
                  Worldport Network Interface points specified above is to
                  provide performance levels over a 12 month period as follows:

                  This excludes any customer provided access links to the
                  Worldport digital network.

                  2.4      Outages attributable to incidental damage to or
                  severage of outside fiber optic cable plant, or scheduled
                  maintenance is excluded from the performance objective stated
                  above.

                  2.5      Error-Free Seconds (EFS) and Error Seconds (ES) are
                  the primary measure of error performance. An Error-Free Second
                  is defined as any second in which no bit errors are received.
                  Conversely, an Error Second is any second in which one or more
                  bit errors are received.

         SONET : Synchronous Optical Network is a family of optical transmission
         rates and interface standards allowing internetworking of products from
         different vendors. Base optical rate is 51.840 Mb/s. Higher rates are
         direct multiples.

         SONET TRANSPORT : Services associated with carrying OC-1 or higher
         level signals.

         SYNCHRONOUS TRANSPORT SIGNAL LEVEL 1 (STS-1) : The basic logical
         building block electrical signal with a rate of 51.840 Mb/s.

         SYNCHRONOUS TRANSPORT SIGNAL LEVEL N (STS-N) : This electrical signal
         is obtained by byte interleaving N STS-1 signals together. The rate of
         the STS-N is N times 51.840 Mb/s.

         TERMINATING MULTIPLEX (TM) : Provides the multiplex functions for
         multiplexing and demultiplexing between the DS1 or higher signal level
         and the SONET OC-N level.

         ACCEPTANCE CRITERIA. The acceptance criteria for DS1, DS3, and
         OC-3/STM-1 circuits between Worldport Network Interface points is to
         provide the performance levels shown below during a 60 minute test
         period. If no errors are observed during the first 15 minutes of the
         test, the facility may be considered acceptable. Access connections to
         customer location will be tested in accordance with Bell Publication
         62508.

                  The tables below are based on QCC owned fiber optic network
                  only and on the Bellcore Specifications of the SONET delivery
                  of DS1, DS3, and OC-3/STM-3 directly off the SONET Backbone.

                  If the DS1, DS3, and OC-3/STM-1 service is delivered at the
                  STS1 level then the general performance objectives fall into
                  the industry standard.

1.       Protection and Restoration of Service. Worldport at all times will
         protect and restore STAR's Capacity as follows:

         a.       In the event of a total or partial failure of Worldport's
Network which includes or in any way affects the performance of the Capacity,
Worldport will take immediate action to restore the full and complete use of the
Capacity via redundant and diverse terrestrial fiber optic cable facilities.
Restoration of the Capacity will have the same priority as that of Worldport's
Network including capacity which may be assigned and used by Worldport or its
Affiliates. The complete restoration of the Capacity provided under this
Agreement will be implemented by Worldport in a manner consistent with industry
standards and shall be immediate and complete in scope and to STAR's and its
Affiliates' satisfaction. In the event a failure occurs to the Capacity which
interrupts, i.e., results in the Capacity being unrestored for any period,
Worldport will provide outage credits to STAR and its Affiliates according to
the provisions of this Agreement.

         b.       To ensure damage prevention, Worldport will take reasonable
and customary steps to protect the physical integrity of its network.

         c.       In all cases Worldport shall provide fiber optic transmission
systems equipped with both a working system and a stand-by protection system,
commonly referred to as one-for-one protection, which automatically implements a
switch to the stand-by fiber facility/channel upon a failure of the working
channel. In the event of an electronics/optronics equipment failure on the
working system, the system will switch to the standby or protection hardware.

         d.       Worldport will provide when available network monitoring and
surveillance and monitor the fiber routes by monitoring for the loss of optical
signal on Worldport-maintained electronics installed on the fiber, subject to
Worldport and STAR and its Affiliates executing a mutually acceptable agreement.
This will be done through a Worldport-operated Network Operations Center (NOC)
which operates seven (7) days a week, twenty-four (24) hours per day.
Worldport's NOC will utilize a network management system which provides this
function and will provide STAR with remote access capability to their OC3/STM-1
level capacity from Worldport's network management system.

         e.       Worldport will hold regular unannounced fiber restoration
drills to determine the level of readiness of personnel to respond to any
outages. Additionally, Worldport will ensure that all of its operating
facilities are equipped to provide for emergency power in the event that
commercial power is unavailable for any reason. Such emergency power equipment
will be engineered to support the circuit performance needs throughout the
duration of the power outage and until normal operating conditions have been
restored. All of Worldport's operating facilities will be engineered to
withstand hazardous conditions (e.g., hurricanes, floods, etc.).

         f.       Worldport will provide to STAR an Escalation List to be
attached to this Agreement as Exhibit 1 to provide STAR with an escalation
process in the event of emergency or dispute.
