MASTEC, INC. CONSOLIDATED STATEMENTS OF CASH FLOWS (Continued) (dollars in thousands) (Unaudited) Supplemental disclosure of non-cash investing and financing activities: During the six months ended June 30, 2000, we completed certain acquisitions which have been accounted for as purchases. The fair value of the net assets acquired totaled $1.0 million and was comprised primarily of $3.3 million of accounts receivable, $1.8 million of property and equipment, $0.5 million of other assets and $1.4 million in cash, offset by $6.0 million of assumed liabilities. The excess of the purchase price over the net assets acquired was $16.6 million and was allocated to goodwill. MasTec also issued 183,759 shares of common stock with a value of $14.9 million related to the payment of contingent consideration from earlier acquisitions. Of the $14.9 million, $0.2 million was recorded as a reduction of other current liabilities and $14.7 million as additional goodwill. On June 30, 2000, we sold our PCS system in Latin America that was being held for sale for $45.0 million. On July 5, 2000, we received the proceeds related to the sale. Accordingly such proceeds have been reflected as cash in escrow in the accompanying consolidated balance sheet. During the six months ended June 30, 1999, we completed certain acquisitions which have been accounted for as purchases. The fair value of the net assets acquired totaled $3.5 million and was comprised primarily of $7.0 million of accounts receivable, $2.1 million of property and equipment, $0.7 million of other assets and $0.3 million in cash, offset by $6.6 million of assumed liabilities. The excess of the purchase price over the fair value of net assets acquired was $7.8 million and was allocated to goodwill. We also issued 527,597 shares of common stock with a value of $11.3 million related to the payment of contingent consideration from earlier acquisitions. Of the $11.3 million, $2.3 million was recorded as a reduction of other current liabilities and $9.0 million as additional goodwill. The accompanying notes are an integral part of these consolidated financial statements.

MASTEC, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1 - Basis for Presentation of Consolidated Financial Statements The accompanying unaudited consolidated financial statements of MasTec, Inc. have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. They do not include all information and notes required by generally accepted accounting principles for complete financial statements and should be read together with the audited financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 1999. The balance sheet data as of December 31, 1999 was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles. Certain reclassifications have been made to conform to the 2000 presentation. The financial information furnished reflects all adjustments, consisting only of normal recurring accruals, which are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations and cash flows for the quarterly periods presented. The results of operations for the periods presented are not necessarily indicative of our future results of operations for the entire year. Our comprehensive income for the six months ended June 30, 2000 and 1999 was $32.6 million and $5.7 million, respectively. The components of comprehensive income are net income and foreign currency translation adjustments. On June 19, 2000, we effected a three-for-two split of our common stock in the form of a stock dividend to shareholders of record as of May 29, 2000. To reflect the split, common stock was increased and capital surplus was decreased by $1.6 million. All references in the consolidated financial statements to shares and related prices, weighted average number of shares, per share amounts and stock plan data have been adjusted to reflect the stock split on a retroactive basis. Note 2 - Recently Issued Accounting Pronouncements In December 1999, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin No. 101 "Revenue Recognition": (SAB 101), which provides guidance on the recognition, presentation and disclosure of revenue in financial statements filed with the SEC. SAB 101 is applicable beginning with our fourth quarter 2000 consolidated financial statements. Based on our current analysis of SAB 101, we do not believe it will have a material impact on the financial results of the Company. Note 3 - Acquisitions, Investing and Divestitures Activities During 2000, we have completed four acquisitions, two each in our external communication services group and internal communication services group. These acquisitions have been accounted for under the purchase method of accounting. The most significant adjustments to the balance sheet resulting from these acquisitions are disclosed in the supplemental disclosure of non-cash investing and financing activities in the accompanying statement of cash flows. On June 30, 2000, we sold our PCS system in Latin America which was held for sale for a gain of $9.6 million. During the second quarter, we also recorded a charge of $5.4 million comprised primarily of the write-off of two Latin American operations.

Amounts outstanding under the revolving credit facility mature on June 9, 2002. We are required to pay an unused facility fee ranging from .25% to .50% per annum on the facility, depending upon certain financial covenants. The credit facility is secured by a pledge of shares of certain of our subsidiaries. Interest under the credit facility accrues at rates based, at our option, on the agent bank's base rate plus a margin of up to .50% depending on certain financial covenants or 1% above the overnight federal funds effective rate, whichever is higher, or its LIBOR Rate (as defined in the credit facility) plus a margin of 1.00% to 2.25%, depending on certain financial covenants. We also have $200.0 million, 7.75% senior subordinated notes due in February 2008 with interest due semi-annually. The credit facility and the senior notes contain customary events of default and covenants which prohibit, among other things, making investments in excess of a specified amount, incurring additional indebtedness in excess of a specified amount, paying dividends in excess of a specified amount, making capital expenditures in excess of a specified amount, creating certain liens, prepaying other indebtedness, including the senior notes, and engaging in certain mergers or combinations without the prior written consent of the lenders. The credit facility also provides that we must maintain certain financial ratio coverage, requiring, among other things minimum ratios at the end of each fiscal quarter of debt to earnings and earnings to interest expense. Note 5 - Operations by Segments and Geographic Areas We currently derive a substantial portion of our revenue from providing external communication services to Bell South Telecommunications, Inc. For the six months ended June 30, 2000, approximately 10% of our domestic revenue was derived from services performed for them. The following table set forth, for the three months and six months ended June 30, 2000 and 1999, certain information about segment results of operations and segment assets (in thousands):

As of June 30, 2000 and 1999, total assets for Brazil consisted of $50.4 million and $86.8 million, respectively and the remainder relates to our interest in international assets not related to our core business.

(2) Consists of non-core construction and corporate operations, which includes interest expense net of interest income of $8.2 million and $8.8 million for the six months ended June 30, 2000 and 1999, respectively. For the three months ended June 30, 2000 and 1999, the interest expense, net of interest income was $3.5 million and $4.4 million, respectively. There are no significant transfers between geographic areas and segments. Total assets are those assets used in our operations in each segment. Corporate assets include cash and cash equivalents, real estate assets held for sale and notes receivable. Note 6 - Commitments and Contingencies In November 1997, we filed a lawsuit against Miami-Dade County in Florida state court alleging breach of contract and seeking damages exceeding $3.0 million in connection with the county's refusal to pay amounts due us under a multi-year agreement to perform road restoration work for the Miami-Dade Water and Sewer Department ("MWSD"), a department of the county, and the county's wrongful termination of the agreement. The County has refused to pay amounts due to us under the agreement until alleged overpayments under the agreement have been resolved, and has counterclaimed against us seeking unspecified damages. We are vigorously pursuing this lawsuit. We own minority interests in Argentina and Spain. Our investment in Argentina is a minority interest with a carrying value of $17.9 million as of June 30, 2000 in Supercanal Holding, S.A., a holding company of numerous cable television operators in western Argentina ("Supercanal"). We also own an indirect minority interest in and have made a $3.0 million working capital loan to Sistemas e Instalaciones de Comunicacion, S.A. ("Sintel"), a Spanish telecommunications infrastructure services provider. Supercanal has defaulted on its third party debt and has filed a petition under Argentine law seeking protection from its creditors. We do not guarantee any of this indebtedness. In January 2000, the majority shareholder of Supercanal approved a capital increase that would have required us to contribute approximately $5.9 million to maintain our interest if the capital increase is effected in full, but the capital increase has been enjoined by an Argentine judge and we cannot determine whether or when the capital increase will be effected. During the second quarter of 2000, Sintel filed a petition under Spanish law seeking protection from its creditors, including our working capital loan. In July 2000, Sintel approved a capital increase that will require us to contribute approximately $2.6 million to maintain our interest if the capital increase is effected in full. Management is considering whether to subscribe to the capital increase. We have determined that the carrying value of these assets has not been impaired, but we are monitoring investments to determine whether a charge is warranted in the future. Our current and future operations and investments in certain foreign countries are generally subject to the risks of political, economic or social instability, including the possibility of expropriation, confiscatory taxation, hyper-inflation or other adverse regulatory or legislative developments, or limitations on the repatriation of investment income, capital and other assets. We cannot predict whether any of such factors will occur in the future or the extent to which such factors would have a material adverse effect on our international operations.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION Except for historical information, the matters discussed below are forward looking statements made pursuant to the safe harbor provisions for forward-looking statements described in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on the Company's current expectations and are subject to a number of risks, uncertainties and assumptions relating to the Company's operations, financial condition and results of operations. Should one or more of these risks or uncertainties materialize, or should the underlying assumptions prove incorrect, actual results may differ significantly from results expressed or implied in any forward-looking statements made by the Company in this Quarterly Report. These and other risks are detailed in documents filed by the Company with the Securities and Exchange Commission. The Company does not undertake any obligation to revise these forward-looking statements to reflect future events or circumstances. General We design, build, install, maintain and monitor internal and external networks supporting the Internet, Internet-related applications, e-commerce and other communications and energy facilities for leading telecommunications, cable television, energy and other Fortune 500 companies. Based on revenue, we are the largest end-to-end telecommunications and energy infrastructure service provider in North America. We offer comprehensive network infrastructure solutions to a diverse group of customers, enabling our customers to connect with their customers. Currently, we operate from approximately 200 locations throughout North America, which accounted for 96% of our revenue for the six months ended June 30, 2000. Internationally we operate in Brazil through a 51% joint venture which we consolidate net of a 49% minority interest after tax. For the six months ended June 30, 2000, approximately 10.7% of our domestic revenue was derived from services performed for BellSouth Telecommunications, Inc. Our top 10 customers combined account for approximately 50% of our domestic revenue in the quarter. We report our operations in four segments: - External Communication Services, - External Energy Services, - Internal Communication Services and - International.

Results of Operations North America The following table states for the periods indicated our North American operations in dollar and percentage of revenue terms (in thousands): Three Months Ended June 30, Six Months Ended June 30, ---------------------------------------------- ---------------------------------------------- 2000 1999 2000 1999 ----------------------- ---------------------- ---------------------- ----------------------- Revenue $ 286,418 100.0% $ 225,162 100.0% $ 548,790 100.0% $ 413,384 100.0% Costs of revenue 215,653 75.3% 169,305 75.2% 416,342 75.9% 316,381 76.5% Depreciation 13,183 4.6% 11,715 5.2% 26,661 4.9% 22,094 5.3% Amortization 1,698 0.6% 1,399 0.6% 3,170 0.6% 2,792 0.7% General and administrative 20,582 7.2% 18,510 8.2% 42,260 7.7% 36,016 8.8% expenses Three Months Ended June 30, 2000 Compared to Three Months Ended June 30, 1999 The following table sets forth the revenue and change in revenue by North American operating segments, in dollar and percentage terms (in thousands): Three Months Ended June 30, Change ----------------------------- ----------------------------- 2000 1999 $ % -------------- ------------- ------------- ------------- External Communication Services $ 209,018 $ 167,642 $ 41,376 24.7% External Energy Services 36,891 38,186 (1,295) (3.4%) Internal Communication Services 40,509 19,003 21,506 113.2% Other - 331 (331) (100.0%) ============== ============= ============= ------------- $ 286,418 $ 225,162 $ 61,256 27.2% ============== ============= ============= Our North American revenue was $286.4 million for the three months ended June 30, 2000, compared to $225.2 million for the same period in 1999, representing an increase of $61.3 million or 27.2% primarily all organic. Revenue from our two combined segments offering services to the datacom world increased by 33.7%. Of our three operating segments, the fastest growing is our internal communication services primarily due to growth in services provided at central office facilities resulting from regulatory co-location requirements to open central office facilities to new competitors. Our external communication services segment is also growing primarily due to the increased demand for bandwidth by end-users which has spurred increased network construction and upgrades by our customers. Our external energy segment decreased slightly due to our focus on increasing profitability prior to any future growth. During the three months ended June 30, 2000, we completed four acquisitions, two in our external communications segment and two in our internal communication services segment. This compares to two acquisitions for the three months ended June 30, 1999 in our external communication services segment. Our North American costs of revenue was $215.7 million or 75.3% of revenue for the three months ended June 30, 2000, compared to $169.3 million or 75.2% of revenue for the same period in 1999. In 2000, margins decreased due to increased training costs in our external communication services offset by increased value added service offering in our internal communication services and inceased efficiency in our energy segment.

Depreciation expense was $13.2 million or 4.6% of revenue for the three months ended June 30, 2000, compared to $11.7 million or 5.2% of revenue for the same period in 1999. The increased depreciation expense resulted from our investment in our fleet to support revenue growth. The decline as a percentage of revenue was due to an increase in revenue from our internal communication segment which is less capital intensive. General and administrative expenses were $20.6 million or 7.2% of revenue for the three months ended June 30, 2000, compared to $18.5 million or 8.2% of revenue for the same period in 1999. The decline in general and administrative expenses as a percentage of revenue for the three months ended June 30, 2000 was due primarily to our ability to support higher revenue with a reduced administrative base. Six Months Ended June 30, 2000 Compared to Six Months Ended June 30, 1999 The following table sets forth the revenue and change in revenue by North American operating segments, in dollar and percentage terms (in thousands): Six Months Ended June 30, Change ----------------------------- ----------------------------- 2000 1999 $ % -------------- ------------- ------------- ------------- External Communication Services $ 402,009 $ 296,520 $ 105,489 35.6% External Energy Services 74,254 75,136 (882) (1.2%) Internal Communication Services 72,527 40,306 32,221 79.9% Other - 1,422 (1,422) (100.0%) ============== ============= ============= ------------- $ 548,790 $ 413,384 $ 135,406 32.8% ============== ============= ============= Our North American revenue was $548.8 million for the six months ended June 30, 2000, compared to $413.4 million for the same period in 1999, representing an increase of $135.4 million or 32.8%, primarily all organic. Revenue from our two combined segments offering services to the datacom world increased by 40.9%. Of our three operating segments, the fastest growing is our internal communication services primarily due to growth in services provided at central office facilities resulting from regulatory co-location requirements to open central office facilities to new competitors. Our external communication services segment is also growing primarily due to the increased demand for bandwidth by end-users which has spurred increased network construction and upgrades by our customers. Our external energy segment remained relatively constant due to our focus to increasing profitability prior to any future growth. During the six months ended June 30, 2000, we completed four acquisitions, two in our external communications segment and two in our internal communications services segment. This compares to three acquisitions for the six months ended June 30, 1999 in our external communication services segment. Our North American costs of revenue were $416.3 million or 75.9% of revenue for the six months ended June 30, 2000, compared to $316.4 million or 76.5% of revenue for the same period in 1999. In 2000, margins improved due to increased productivity in our external and internal communication services offset by a slight decline in our energy segment due to poor weather conditions experienced earlier in 2000. Depreciation expense was $26.7 million or 4.9% of revenue for the six months ended June 30, 2000, compared to $22.1 million or 5.3% of revenue for the same period in 1999. The increased depreciation expense resulted from our investment in our fleet to support revenue growth. The decline as a percentage of revenue was due to an increase in revenue from our internal communication segment which is less capital intensive. General and administrative expenses were $42.3 million or 7.7% of revenue for the six months ended June 30, 2000, compared to $36.0 million or 8.8% of revenue for the same period in 1999. The decline in general and administrative expenses as a percentage of revenue for the six months ended June 30, 2000 was due primarily to our ability to support higher revenue with a reduced administrative base.

International The following tables set forth for the periods indicated our Brazilian operations in dollar and percentage terms (in thousands): Three Months Ended June 30, Six Months Ended June 30, --------------------------------------------- ---------------------------------------------- 2000 1999 2000 1999 ---------------------- ---------------------- ---------------------- ---------------------- Revenue $ 11,279 100.0% $ 13,525 100.0% $ 21,601 100.0% $ 32,100 100.0% Costs of revenue 9,280 82.3% 8,964 66.3% 17,520 81.1% 23,985 74.7% Amortization 977 8.7% 753 5.6% 3,006 13.9% 1,628 5.1% General and administrative 1,348 12.0% 2,032 15.0% 2,782 12.9% 3,917 12.2% expenses Three Months Ended June 30, 2000 Compared to Three Months Ended June 30, 1999 Our International operations' functional currency is the Brazilian real. Brazilian revenue was $11.3 million for the three months ended June 30, 2000, compared to $13.5 million for the same period in 1999, representing a decrease of $2.2 million or 16.6%. Brazilian revenue decreased primarily due to the completion of prior existing contracts. Brazil had revenue of R$19.6 million reals during the three months ended June 30, 2000, compared to R$23.7 million reals for the same period in 1999, representing a decrease of 17.3%. The average currency exchange rate was 1.74 reals per US dollar for the period ended June 30, 2000 compared to 1.75 reals per US dollar for the same period in 1999. Amortization expense was $1.0 million or 8.7% of revenue for the three months ended June 30, 2000 compared to $0.8 million or 5.6% of revenue for the same period in 1999. Amortization relates primarily to an intangible asset resulting from one acquisition completed in early 1998 that was being amortized over a five year period relative to the volume of work under specified contracts but has been accelerated during 2000. As of June 30, 2000, almost the entire balance has been amortized. General and administrative expenses were $1.3 million or 12% of revenue for the three months ended June 30, 2000, compared to $2.0 million or 15% of revenue for the same period in 1999. General and administrative expenses were R$2.3 million reals or 11.7% of reals revenue during the three months ended June 30, 2000, compared to R$3.6 million reals or 15.2% of reals revenue for the same period in 1999. The decline in general and administrative expenses in relation to revenue in real terms was due to an effort to reduce overhead as the revenue base has declined. Six Months Ended June 30, 2000 Compared to Six Months Ended June 30, 1999 Our International operations' functional currency is the Brazilian real. Brazilian revenue was $21.6 million for the six months ended June 30, 2000, compared to $32.1 million for the same period in 1999, representing a decrease of $10.5 million or 32.7%. Brazilian revenue decreased primarily due to the completion of prior existing contracts. Brazil had revenue of R$37.4 million reals during the six months ended June 30, 2000, compared to R$54.2 million reals for the same period in 1999, representing a decrease of 31.0%. The average currency exchange rate was 1.73 reals per US dollar for the period ended June 30, 2000 compared to 1.69 reals per US dollar for the same period in 1999. Amortization expense was $3.0 million or 13.9% of revenue for the six months ended June 30, 2000 compared to $1.6 million or 5.1% of revenue for the same period in 1999. Amortization relates primarily to an intangible asset resulting from one acquisition completed in early 1998 that was being amortized over a five year period relative to the volume of work under specified contracts but has been accelerated during 2000. As of June 30, 2000, almost the entire balance has been amortized. General and administrative expenses were $2.8 million or 12.9% of revenue for the six months ended June 30, 2000, compared to $3.9 million or 12.2% of revenue for the same period in 1999. General and administrative expenses were R$4.8 million reals or 12.8% of reals revenue during the six months ended June 30, 2000, compared to R$6.6 million reals or 12.2% of reals revenue for the same period in 1999. The decline in general and administrative expenses in relation to revenue in real terms was due to an effort to reduce overhead as the revenue base has declined. Consolidated Results The following table sets forth for the periods indicated certain consolidated income statement data for North America and International and the related percentage of consolidated revenue. Three Months Ended June 30, Six Months Ended June 30, ---------------------------------------------------------------------------------------------- 2000 1999 2000 1999 ----------------------- ---------------------------------------------- ----------------------- Interest expense $ (4,303) (1.4%) $ (7,311) (3.1%) $ (9,859) (1.7%) $ (13,542) (3.0%) Interest income 1,054 0.4% 3,633 1.5% 2,267 0.4% 5,742 1.3% Other income, net 4,873 1.6% 178 0.1% 5,253 0.9% 301 - Income before provision for 36,600 12.3% 22,510 9.4% 56,311 9.9% 31,172 7.0% income taxes and minority interest Provision for income taxes (15,120) (5.1%) (9,279) (3.9%) (23,499) (4.1%) (12,949) (2.9%) Minority interest (138) - (1,054) (0.4%) 7 - (1,694) (0.4%) ============ ========== ============ ======================= ========= ============ ========== Net income $ 21,342 7.2% $ 12,177 5.1% $ 32,819 5.8% $ 16,529 (3.7%) ============ ========== ============ ======================= ========= ============ ========== Three Months Ended June 30, 2000 Compared to Three Months Ended June 30, 1999 For the three months ended June 30, 2000, interest expense declined from $7.3 million to $4.3 million primarily due to the repayment of debt under our revolving credit facility with a portion of the proceeds of our offering of 3.75 million shares which raised approximately $126.0 million in net proceeds. Interest income for the three months ended June 30, 1999 includes interest accrued and collected from a customer financing arrangement which terminated in September 1999. Interest income for the three months ended June 30, 2000 was mainly comprised of interest earned on temporary investments as a result of our 3.75 million equity offering completed in March 6, 2000. For the three months ended June 30, 2000, we reflected a gain of $9.6 million related to the sale of our PCS system in Latin America. We also recorded a charge of $5.4 million comprised primarily of the write-off of two Latin American operations. Reflected in other income, net for the three months ended June 30, 1999, are the following transactions. MasTec sold assets held for sale with a book value of approximately $9.7 million for approximately $6.1 million recognizing a loss on sale of approximately $3.6 million. Offsetting the loss from disposal of non-core assets was a fee of $3.5 million collected from a telecommunications customer related to a vendor financing arrangement. Our effective tax rate for North American and Brazil operations approximates 42% and 33% respectively, for the three and six months ended June 30, 2000 and 1999. The trends experienced during the three months ended June 30, 2000 are consistent with those of the six months ended June 30, 2000 to six months ended June 30, 1999.

Financial Condition, Liquidity and Capital Resources Our primary liquidity needs are for working capital, capital expenditures, acquisitions and investments, and debt service. Our primary sources of liquidity are cash flows from operations, borrowings under revolving lines of credit, issuances of stock and the proceeds from the sale of assets held for sale. Net cash used in operating activities was $10.6 million for the six months ended June 30, 2000, compared to net cash provided by operating activities of $22.2 million for the same period in 1999. In 1999, we collected approximately $42.0 million from a customer to whom we were providing vendor financing of which approximately $14.3 million related to work performed in 1999 with the balance being for work performed in 1998. Our working capital at June 30, 2000, excluding assets held for sale of $24.7 million, was $279.9 million compared to $169.6 million at December 31, 1999 excluding assets held for sale of $53,639. Our North American working capital as of June 30, 2000 was comprised primarily of $265.2 million in accounts receivable, $36.9 million in inventories and other current assets and $75.4 million in cash and cash in escrow, net of $118.5 million in current liabilities. We have a credit facility that provides for borrowings up to an aggregate amount of $100.0 million, which we have reduced from $165.0 million during 2000. Amounts outstanding under the revolving credit facility mature on June 9, 2002. We are required to pay an unused facility fee ranging from .25% to .50% per annum on the facility, depending upon certain financial covenants. The credit facility is secured by a pledge of shares of certain of our subsidiaries. Interest under the credit facility accrues at rates based, at our option, on the agent bank's base rate plus a margin of up to .50% depending on certain financial covenants or 1% above the overnight federal funds effective rate, whichever is higher, or its LIBOR Rate (as defined in the credit facility) plus a margin of 1.00% to 2.25%, depending on certain financial covenants. We also have $200.0 million, 7.75% senior subordinated notes due in February 2008 with interest due semi-annually. The credit facility and the senior notes contain customary events of default and covenants which prohibit, among other things, making investments in excess of a specified amount, incurring additional indebtedness in excess of a specified amount, paying dividends in excess of a specified amount, making capital expenditures in excess of a specified amount, creating certain liens, prepaying other indebtedness, including the senior notes, and engaging in certain mergers or combinations without the prior written consent of the lenders. The credit facility also provides that we must maintain certain financial ratio coverages, requiring, among other things, minimum ratios at the end of each fiscal quarter of debt to earnings and earnings to interest expense. During 2000, we invested $28.3 million primarily in our fleet to support revenue growth. We collected $15.2 million in net proceeds related to assets sold, primarily from the sale of our Spanish operations. Subsequent to June 30, 2000, we received $45.0 million in proceeds held in escrow at June 30 from the sale of our PCS system in Latin America in the second quarter. We anticipate that available cash, cash flows from operations and the proceeds from the sale of assets and investments and borrowing availability under the Credit Facility will be sufficient to satisfy our working capital requirements for the foreseeable future. We also own minority interests in Argentina and Spain. Our investment in Argentina is a minority interest with a carrying value of $17.9 million as of June 30, 2000 in Supercanal Holding, S.A., a holding company of numerous cable television operators in western Argentina ("Supercanal"). We also own a minority interest in and have made a $3.0 million working capital loan to Sistemas e Instalaciones S.A. ("Sintel"), a Spanish telecommunications infrastructure services provider. Supercanal has defaulted on its third party debt and has filed a petition under Argentine law seeking protection from its creditors. We do not guarantee any of this indebtedness. In January 2000, the majority shareholder of Supercanal approved a capital increase that would have required us to contribute approximately $5.9 million to maintain our interest if the capital increase is effected in full, but the capital increase has been enjoined by an Argentine judge and we cannot determine whether or when the capital increase will be effected.

During the second quarter of 2000, Sintel filed a petition under Spanish law seeking protection from its creditors, including our working capital loan. In July 2000, Sintel approved a capital increase that will require us to contribute approximately $2.6 million to maintain our interest if the capital increase is effected in full. Management is considering whether to subscribe to the capital increase. We have determined that the carrying value of these assets has not been impaired, but we are monitoring investments to determine whether a charge is warranted in the future. While we do not currently anticipate taking an additional impairment charge on any of these assets, there can be no assurance that future transactions or events will not result in any further impairment of these assets. If we were to take a charge, however, it could adversely affect our earnings for the period in which we incurred the charge. Seasonality Our North America operations have historically been seasonally weaker in the first and fourth quarters of the year and have produced stronger results in the second and third quarters. This seasonality is primarily the result of customer budgetary constraints and preferences and the effect of winter weather on external network activities. Some of our U.S. customers, particularly the incumbent local exchange carriers, tend to complete budgeted capital expenditures before the end of the year and defer additional expenditures until the following budget year. Revenue in reals from our Brazilian operations is not expected to fluctuate seasonally. Impact of Inflation The primary inflationary factor affecting our operations is increased labor costs. We have experienced some increases in labor costs. Competition for qualified personnel could increase labor costs for us further in the future. Our international operations may, at times in the future, be exposed to high inflation in certain foreign countries. During the six months ended June 30, 2000, we generated approximately 4% of our total revenue from our Brazilian operations that are susceptible to currency devaluation. We anticipate that revenue from our Brazilian operations will be less significant to our operations in the foreseeable future due to our continued focus on domestic operations. In addition, any deterioration in economic conditions in Brazil and other Latin American countries could adversely impact our results of operations, financial position and cash flows. ITEM 3.
