MasTec, Inc.
Notes to the Condensed Unaudited Consolidated Financial Statements

Note 1 — Nature of the Business

     MasTec, Inc. (collectively, with its subsidiaries, “MasTec”, “we,” “us,” “our” or the “Company”) is a leading specialty contractor operating mainly throughout the United States and across a range of industries. Our core activities are the building, installation, maintenance and upgrade of communications and utility infrastructure. Our primary customers are in the following industries: communications (including satellite television and cable television), utilities and government. MasTec provides similar infrastructure services across the industries it serves. Customers rely on us to build and maintain infrastructure and networks that are critical to their delivery of voice, video and data communications, electricity and other energy resources.

Note 2 — Basis for Presentation

     The accompanying condensed unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions for Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these financial statements do not include all information and notes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2006. In our opinion, all adjustments necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included.

     The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Key estimates for us include the recognition of revenue for costs and estimated earnings in excess of billings, allowance for doubtful accounts, accrued self-insured claims, the fair value of goodwill and intangible assets, asset lives used in computing depreciation and amortization, including amortization of intangibles, and accounting for income taxes, contingencies and litigation. While we believe that such estimates are fair when considered in conjunction with the consolidated financial position and results of operations taken as a whole, actual results could differ from those estimates and such differences may be material to the financial statements.

Note 3 — Significant Accounting Policies

(a) Principles of Consolidation

     The accompanying financial statements include MasTec, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. As discussed in Note 4, in the first quarter of 2007, we began consolidating the financial statements of an entity in which we acquired majority ownership effective February 1, 2007.

(b) Comprehensive Income (Loss)

     Comprehensive income (loss) is a measure of net income (loss) and all other changes in equity that result from transactions other than with shareholders. Comprehensive income (loss) consists of net income (loss) and foreign currency translation adjustments.

     Comprehensive income (loss) consisted of the following (in thousands):

	For the Three					For the Six
	Months Ended					Months Ended

	2007		2006			2007		2006

Notes to the Condensed Unaudited Consolidated Financial Statements

(c) Basic and Diluted Net Income (Loss) Per Share

     The computation of basic net income (loss) per share is based on the weighted average number of common shares outstanding during the period. The computation of diluted net income (loss) per common share is based on the weighted average of common shares outstanding during the period plus, when their effect is dilutive, incremental shares consisting of shares subject to stock options and unvested restricted stock (“common stock equivalents”). For the three and six months ended June 30, 2007, diluted net income (loss) per common share includes the effect of common stock equivalents in the amount of approximately 1,577,000 shares and 1,441,000 shares, respectively. For the three and six months ended June 30, 2006, diluted net income (loss) per common share includes the effect of approximately 1,711,000 shares and 1,694,000 shares, respectively, of common stock equivalents.

(d) Valuation of Goodwill and Intangible Assets

     In accordance with Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (“SFAS 142”), we conduct, on at least an annual basis, a review of our reporting entities to determine whether the carrying values of goodwill exceed the fair market value using a discounted cash flow methodology for each entity. Should this be the case, the value of its goodwill may be impaired and written down. Goodwill acquired in a purchase business combination and determined to have an infinite useful life is not amortized, but instead tested for impairment at least annually in accordance with provisions of SFAS No. 142.

     As discussed in Note 7, we wrote-off approximately $0.4 million in goodwill in connection with our decision to sell our Canadian operations during the six month period ended June 30, 2007.

     During the six months ended June 30, 2007, we recorded approximately $29.4 million of goodwill and other intangible assets in connection with the acquisition described in Note 4.

(e) Accrued Insurance

     MasTec maintains insurance policies subject to per claim deductibles of $1 million for its workers’ compensation policy, $2 million for its general liability policy and $3 million for its automobile liability policy. We have excess umbrella coverage for losses in excess of the primary coverages of up to $100 million per claim and in the aggregate. These insurance liabilities are actuarially determined on a quarterly basis for unpaid claims and associated expenses, including the ultimate liability for claims incurred and an estimate of claims incurred but not reported. During the three month period ended June 30, 2007, we changed the discount factor used in estimating the actuarial insurance reserve for our workers’ compensation, general liability and auto liability policies from a spot rate of 5.2% applied to all future expected cash outflows, to the Citigroup Pension Discount Curve, which was developed to improve the matching of discount rates across multiple periods with projected future cash outflows in those periods. The curve is derived from U.S. Treasury rates, plus an option-adjusted spread varying by maturity to better reflect the settlement rate used to discount estimated future cash payments. We also maintain an insurance policy with respect to employee group health claims subject to per claim deductibles of $300,000 after satisfying an aggregate annual deductible of $100,000. The accruals are based upon known facts, historical trends and a reasonable estimate of future expenses. However, a change in experience or actuarial assumptions could nonetheless materially affect results of operations in a particular period. Known amounts for claims that are in the process of being settled, but have been paid in periods subsequent to those being reported, are also recorded in such reporting period.

(f) Stock Based Compensation

     We have granted to employees and others restricted stock and options to purchase our common stock. Total non-cash stock compensation expense for the three months ended June 30, 2007 and 2006 was $1.5 million and $2.0 million, respectively, which is included in general and administrative expense in the condensed unaudited consolidated statements of operations. Total non-cash stock compensation expense for the six months ended June 30, 2007 and 2006 was $3.5 million and $3.4 million, respectively, of which $0 million and $0.2 million, respectively, was included in loss

Notes to the Condensed Unaudited Consolidated Financial Statements

from discontinued operations, and $3.5 million and $3.2 million, respectively, is included in general and administrative expense in the condensed unaudited consolidated statements of operations.

     Non-cash compensation expense related to stock options amounted to approximately $1.0 million and $1.7 million, respectively, during the three months ended June 30, 2007 and 2006, which is included in general and administrative expense in the condensed unaudited consolidated statements of operations. Included in general and administrative expense for the three month period ended June 30, 2006 is approximately $0.1 million of compensation expense related to the acceleration of stock option grants that occurred in the three months ended June 30, 2006. These accelerations were a result of certain benefits given to employees whose employment ceased during the three month period. There were no options granted during the three months ended June 30, 2007. During the three months ended June 30, 2006, we granted to certain employees, directors and executives the right to purchase 799,500 shares of MasTec’s common stock at the current market price per share at the time of the option grant. The options granted during the three months ended June 30, 2006 had a weighted average exercise price of $13.92 per share. The weighted average fair value of options granted during the three month period ended June 30, 2006 was $8.52 per share.

     Non-cash compensation expense related to stock options amounted to approximately $2.5 million, and $2.9 million, respectively, during the six months ended June 30, 2007 and 2006, of which $0.2 million for 2006 is included in loss from discontinued operations, and $2.5 million and $2.7 million, respectively, is included in general and administrative expense in the condensed unaudited consolidated statements of operations. Included in general and administrative expense for the six month period ended June 30, 2006 is approximately $0.4 million of compensation expense related to the acceleration of stock option grants that occurred in the six months ended June 30, 2006. These accelerations were a result of certain benefits given to employees whose employment ceased during the six month period. There were no options granted during the six months ended June 30, 2007. During the six months ended June 30, 2006, we granted to certain employees, directors and executives the right to purchase 799,500 shares of MasTec’s common stock at the current market price per share at the time of the option grant. The options granted during the six months ended June 30, 2006 had a weighted average exercise price of $13.92 per share. The weighted average fair value of options granted during the six month period ended June 30, 2006 was $8.52 per share.

     We use the Black-Scholes valuation model to estimate the fair value of options to purchase our common stock and use the ratable method (an accelerated method of expense recognition under SFAS 123R) to amortize compensation expense over the vesting period of the option grant.

     The fair value of each option granted was estimated using the following assumptions:

	For the Three Months Ended						For the Six Months Ended
	June 30,						June 30,
	2007			2006			2007			2006
Expected life — employees	4.26 — 7.00 years			4.26 — 6.26 years			4.26 — 7.00 years			4.26 — 6.29 years
Expected life — executives	5.74 — 9.74 years			5.74 — 9.74 years			5.74 — 9.74 years			5.74 — 9.74 years
Volatility percentage		40% — 55	%		40% — 65	%		40% — 60	%		40% — 65	%
Interest rate		4.54% — 4.84	%		5.08% — 5.16	%		4.96% — 5.10	%		4.97% — 5.14	%
Dividends	None			None			None			None
Forfeiture rate		7.26	%		7.27	%		7.48	%		7.19	%

     We also sometimes grant restricted stock, which is valued based on the market price of our common stock on the date of grant. Compensation expense arising from restricted stock grants is recognized using the ratable method over the vesting period. Unearned compensation for performance-based options and restricted stock is shown as a reduction of shareholders’ equity in the condensed unaudited consolidated balance sheets. Through June 30, 2007, we have issued 507,357 shares of restricted stock valued at approximately $5.5 million which is being expensed over various vesting periods (12 months to 4 years). Total unearned compensation related to restricted stock grants as of June 30, 2007 is approximately $2.7 million. Restricted stock expense for the three and six months ended June 30, 2007 is approximately $0.4 million and $1.0 million, respectively, and is included in general and administrative expenses in the condensed unaudited statements of operations. Restricted stock expense for the three and six months ended June 30, 2006 was

MasTec, Inc.
Notes to the Condensed Unaudited Consolidated Financial Statements

approximately $0.4 million and $0.6 million, respectively, and is included in general and administrative expenses in the condensed unaudited statements of operations.

(g) Reclassifications

     Certain reclassifications were made to the prior period financial statements in order to conform to the current period presentation. In addition, as discussed in Note 7, in March 2007 we reached the decision to sell substantially all of our Canadian operations. Accordingly, the net loss for these operations for the three and six months ended June 30, 2006 have been reclassified from the prior period presentation as a loss from discontinued operations in our condensed unaudited consolidated statements of operations. In addition, current and long-term assets, as well as current and non-current liabilities, have been reclassified on the consolidated balance sheet as of December 31, 2006 to conform to the current presentation.

(h) Equity investments

     Through January 2007 we owned 49% in DirectStar TV LLC (“DirectStar”). We accounted for our 49% interest under the equity method as we had the ability to exercise significant influence, but not control, over the operational policies of the company. Our share of earnings or losses in this investment through January 2007 is included as other income, net in the condensed unaudited consolidated statements of operations. As discussed in Note 4, effective February 1, 2007, we acquired the remaining 51% equity interest in this entity, and accordingly, we have consolidated their operations with our results commencing in February 2007. As of December 31, 2006, our investment in DirectStar exceeded the net equity of such investment and the excess is considered to be equity goodwill.

(i) Fair value of financial instruments

     We estimate the fair market value of financial instruments through the use of public market prices, quotes from financial institutions and other available information. Judgment is required in interpreting data to develop estimates of market value and, accordingly, amounts are not necessarily indicative of the amounts that we could realize in a current market exchange. Short-term financial instruments, including cash and cash equivalents, accounts and notes receivable, accounts payable and other liabilities, consist primarily of instruments without extended maturities, the fair value of which, based on management’s estimates, equaled their carrying values. At June 30, 2007, the fair value of our outstanding senior notes was approximately $150.4 million. At December 31, 2006, the fair value of our outstanding senior subordinated notes was approximately $121.0 million.

(j) Income taxes

     In the past, we conducted business in the United States, as well as various territories outside of the United States. As a result, through one or more of our subsidiaries, we file income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. In the normal course of business we are subject to examination by taxing authorities in certain foreign locations, including such major jurisdictions as Canada, Brazil and the United States. With few exceptions, we are no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations for years before 2003.

     We are currently under audit by the Internal Revenue Service for the 2004 tax year. The examination phase of the audit concluded in the three months ended June 30, 2007, and we have received preliminary indication that the IRS will recommend no change to the tax return we filed for that year. Until such time as we receive a formal notice of conclusion to this audit, or as a result of the expiration of the statute of limitations for specific jurisdictions, it is possible that the related unrecognized tax benefits for tax positions taken regarding previously filed tax returns could change from those recorded for uncertain income tax positions in our financial statements. In addition, the outcome of the examination may impact the valuation of certain deferred tax assets (such as net operating losses) in future periods. Given the procedures for finalizing audits by the Internal Revenue Service, it is not possible to estimate the impact of changes, if any, to previously recorded uncertain tax positions.

     We adopted Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement 109,” (“FIN 48”) in the first quarter of 2007. FIN 48 is an interpretation of FASB Statement No. 109, “Accounting for Income Taxes,” and seeks to reduce the diversity in practice associated with certain aspects of measurement and recognition in accounting for income taxes. FIN 48 prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position that an entity takes or expects to take in a tax return. Under FIN 48, an entity may only recognize or continue to recognize tax positions that meet a “more likely than not” threshold. In the ordinary course of business there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based on management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have recognized the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recognized in our financial statements.

     On January 1, 2007, we recorded the cumulative effect of applying FIN 48 of $1.9 million as an adjustment to the balance of deferred tax assets, and an offset to the valuation allowance on that deferred tax asset. As of the adoption date, we had no accrued interest expense or penalties related to the unrecognized tax benefits. Interest and penalties, if incurred, would be recognized as a component of income tax expense.

Note 4 — Acquisition of Remaining 51% Interest in an Equity Method Investment

     As discussed in Note 3, we had a 49% interest in DirectStar. The purchase price for this investment was an initial amount of $3.7 million which was paid in four quarterly installments of $925,000 through December 31, 2005. Beginning in the first quarter of 2006, eight additional contingent quarterly payments were expected to be made to the third party from which the interest was purchased. The contingent payments were to be up to a maximum of $1.3 million per quarter based on the level of unit sales and profitability of the limited liability company in specified preceding quarters. The first five quarterly payments, each of $925,000, were made on January 10, 2006, April 10, 2006, July 11, 2006, October 10, 2006 and January 10, 2007. The January 10, 2007 amount is included in accrued expenses and other assets at December 31, 2006. In March 2006, DirectStar requested an additional capital contribution in the amount of $2.0 million of which $980,000, or 49%, was paid by MasTec.

     Effective February 1, 2007, we acquired the remaining 51% equity interest in this investment. As a result of our acquisition of the remaining 51% equity interest, we have consolidated the operations of DirectStar with our results commencing in February 2007. In February 2007, we paid the seller $8.65 million in cash, in addition to approximately $6.35 million which we also paid at that time to discharge our remaining obligations to the seller under the purchase agreement for the original 49% equity interest, and issued to the seller 300,000 shares of our common stock. This purchase price is subject to adjustments pending finalization of a review of the acquisition date balance sheet. Based on the finalization of this review, we may have to pay the seller additional amounts. We have also agreed to pay the seller an earn-out through the eighth anniversary of the closing date based on the future performance of the acquired business. In connection with the purchase, we entered into a service agreement with the sellers for them to manage the business. Under certain circumstances, including a change of control of MasTec or DirectStar or in certain cases a termination of the service agreement, the remaining earn-out payments will be accelerated and become payable. Under certain circumstances, we may be required to invest up to an additional $3.0 million in DirectStar. In connection with the acquisition, on April 13, 2007, we filed a registration statement to register for resale 200,000 shares of the total shares issued to the seller. On May 15, 2007, this registration statement was declared effective by the SEC.

     Amounts allocated to tangible and intangible assets are estimated pending the completion of independent appraisals and additional analysis currently in process. The estimated preliminary purchase price allocation for the 51% acquisition of this entity is based on the fair-value of each of the components as of February 1, 2007 (in thousands):

Net assets	$	3,281
Tradename		476
Non-compete agreement		311
Other intangibles		6,055
Goodwill		1,588
Purchase price	$	11,711

     The purchase price for the original 49% equity interest exceeded the carrying value of the net assets as of original acquisition date and accordingly the excess was considered goodwill.

     The non-compete agreements are in force with the former shareholders of the acquired entity and are being amortized over their contractual life.

     Prior to the acquisition of the remaining 51% equity interest, we accounted for this investment using the equity method as we had the ability to exercise significant influence over the financial and operational policies of this limited liability company. We recognized approximately $0 and $1.2 million in equity income during the three months ended June 30, 2007 and 2006, respectively, and approximately $0.1 million and $1.6 million during the six months ended June 30, 2007 and 2006, respectively. As of December 31, 2006, we had an investment balance of approximately $15.7 million in relation to this investment included in other assets in the condensed unaudited consolidated financial statements.

Revolving Credit Facility

     We have a secured revolving credit facility under which we may borrow up to $150 million, subject to certain adjustments and restrictions (the “Credit Facility”). Pursuant to an amendment of the Credit Facility that became effective June 30, 2007, the expiration date of the Credit Facility was extended from May 10, 2010 to May 10, 2012. As discussed in Note 12, “Subsequent Events”, this amendment also reduced the interest rate margin applied to borrowings

12

MasTec, Inc.
Notes to the Condensed Unaudited Consolidated Financial Statements

and increased the maximum available amount we can borrow at any given time, among other things. Deferred financing costs related to the Credit Facility are included in prepaid expenses and other current assets, and in other assets in the condensed unaudited consolidated balance sheets.

     The amount that we can borrow at any given time is based upon a formula that takes into account, among other things, eligible billed and unbilled accounts receivable, equipment, real estate and eligible cash collateral, which can result in borrowing availability of less than the full amount of the Credit Facility. As of June 30, 2007 and December 31, 2006, net availability under the Credit Facility totaled $38.0 million and $35.1 million, respectively, which includes outstanding standby letters of credit aggregating $90.7 million and $83.3 million as of such dates, respectively. At June 30, 2007, $69.1 million of the outstanding letters of credit were issued to support MasTec’s casualty and medical insurance requirements. These letters of credit mature at various dates and most have automatic renewal provisions subject to prior notice of cancellation. The Credit Facility is collateralized by a first priority security interest in substantially all of our assets and a pledge of the stock of certain of our operating subsidiaries. Substantially all of our wholly-owned subsidiaries collateralize the Credit Facility. At June 30, 2007 and December 31, 2006, we had no outstanding cash draws under the Credit Facility. Interest under the Credit Facility accrues at variable rates based, at our option, on the agent bank’s base rate plus a margin of between 0.0% and 0.50%, or at the LIBOR rate (as defined in the Credit Facility) plus a margin of between 1.00% and 2.00%, depending on certain financial thresholds. Through December 31, 2007, the Credit Facility provides that the margin over LIBOR will be no higher than 1.125%. The Credit Facility includes an unused facility fee of 0.25%.

     The Credit Facility contains customary events of default (including cross-default) provisions and covenants related to our operations that prohibit, among other things, making investments and acquisitions in excess of specified amounts, incurring additional indebtedness in excess of specified amounts, paying cash dividends, making other distributions, creating liens against our assets, prepaying other indebtedness including our 7.625% senior notes, and engaging in certain mergers or combinations without the prior written consent of the lenders. In addition, any deterioration in the quality of billed and unbilled receivables, reduction in the value of our equipment or an increase in our lease expense related to real estate, would reduce availability under the Credit Facility.

     MasTec is required to be in compliance with a minimum fixed charge coverage ratio of 1.1 to 1.0 measured on a monthly basis and certain events are triggered if the net availability under the Credit Facility does not exceed $15.0 million. The $15.0 million availability trigger is subject to adjustment if the maximum amount we may borrow under the Credit Facility is adjusted. The fixed charge coverage ratio is generally defined to mean the ratio of our net income before interest expense, income tax expense, depreciation expense, and amortization expense minus net capital expenditures and cash taxes to the sum of all interest expense plus current maturities of debt for the period. The financial covenant was not applicable as of June 30, 2007 because at that time the net availability under the Credit Facility did not decline below the required threshold specified above.

Senior Notes

     On January 31, 2007, we issued $150.0 million aggregate principal amount of 7.625% senior notes due February 2017 in a private placement. The notes are guaranteed by substantially all of our domestic restricted subsidiaries. On May 29, 2007, a registration statement registering the unregistered notes was declared effective by the SEC. On May 29, 2007, we commenced an exchange offer whereby holders of our unregistered notes were able to exchange those notes for registered notes. On June 29, 2007, all of the holders of our unregistered notes tendered their unregistered notes for exchange and received a like amount of registered notes in the exchange. We used approximately $121.8 million of the net proceeds from this offering to redeem all of our outstanding 7.75% senior subordinated notes due February 2008 plus interest on March 2, 2007. We expect to use the remaining net proceeds for working capital, possible acquisition of assets and businesses and other general corporate purposes. As of June 30, 2007, we had outstanding $150.0 million in principal amount of these 7.625% senior notes. Interest is due semi-annually. The notes are redeemable, in whole or in part, at our option at anytime on or after February 1, 2012. The initial redemption price is 103.813% of the principal amount, plus accrued interest. The redemption price will decline each year after 2012 and will be 100% of the principal amount, plus accrued interest, beginning on February 1, 2015. The notes also contain default (including cross-default) provisions and covenants restricting many of the same transactions restricted under the Credit Facility.

Notes to the Condensed Unaudited Consolidated Financial Statements

     For the three months ended June 30, 2007, our non-guarantor subsidiaries had revenues of $12.1 million or 4.7% of our consolidated revenues and income from continuing operations of $1.1 million, or 6.7% of our consolidated income from continuing operations. For the six months ended June 30, 2007, our non-guarantor subsidiaries had revenues of $20.5 million, or 4.1% of our consolidated revenues and income from continuing operations of $1.7 million, or 7.5% of our consolidated income from continuing operations. For the three months ended June 30, 2006, our non-guarantor subsidiaries had revenues of $5.4 million or 2.3% of our consolidated revenues and income from continuing operations of $0.2 million or 1.8% of our consolidated income from continuing operations. For the six months ended June 30, 2006, our non-guarantor subsidiaries had revenues of $9.7 million or 2.2% of our consolidated revenues and income from continuing operations of $31,000 or 0.2% of our consolidated income from continuing operations. At June 30, 2007 and December 31, 2006, our non-guarantor subsidiaries had total assets of $18.7 million and $11.5 million, respectively.

Capital Lease Obligations

     During 2007, we entered into agreements which provided financing for various machinery and equipment totaling $5.3 million. These capital leases are non-cash transactions and, accordingly, have been excluded from the condensed unaudited consolidated statements of cash flows. These leases range between 60 and 96 months and have effective interest rates ranging from 4.45% to 7.26%. In accordance with Statement of Financial Accounting Standard No. 13, “Accounting for Leases” (“SFAS 13”), as amended, these leases were capitalized. SFAS 13 requires the capitalization of leases meeting certain criteria, with the related asset being recorded in property and equipment and an offsetting amount recorded as a liability. As of June 30, 2007, we had $12.5 million in total indebtedness relating to the capital leases, of which $10.4 million was considered long-term.

Note 7 — Discontinued Operations

     On March 30, 2007, our board of directors voted to sell substantially all of our Canadian operations. The decision to sell was made after our evaluation of short and long-term prospects for these operations. Due to this decision, the operations in Canada have been accounted for as discontinued operations for all periods presented. In addition, we reviewed the carrying value of the net assets related to our Canadian operations. During the six month period ended June 30, 2007 we wrote-off $0.4 million in goodwill in connection with our decision to sell substantially all of our Canadian net assets. In addition, based on management’s estimate and the expected selling price, we recorded a non-cash impairment charge of approximately $0.2 million.

     On April 10, 2007, we sold substantially all of our Canadian operations for a sales price of approximately $1.0 million. The purchase price is subject to adjustments based on the value of net assets sold as of March 31, 2007.

     The following table summarizes the assets and liabilities related to our Canadian operations as of December 31, 2006 (in thousands):

     On December 31, 2005, the executive committee of our board of directors voted to sell substantially all of our state Department of Transportation related projects and assets. The decision to sell was made after evaluation of, among other things, short and long-term prospects. Due to this decision, the projects and assets that were for sale had been accounted for as discontinued operations for all periods presented. In addition, we reviewed all projects in process to determine if the estimated to complete amounts were materially accurate and all projects with an estimated loss were accrued for. A review of the carrying value of property and equipment related to the state Department of Transportation projects and assets was conducted in connection with the decision to sell these projects and assets. Management assumed a one year cash flow and estimated a selling price using a weighted probability cash flow approach based on management’s estimates.

     On February 14, 2007, we sold the state of Department of Transportation related projects and underlying net assets. We agreed to keep certain assets and liabilities related to the state Department of Transportation related projects. The sales price of $1.0 million was paid in cash at closing. In addition, the buyer is required to pay us an earn out of up to $12.0 million contingent on future operations of the projects sold to the buyer. However, as the earn out is contingent upon the future performance of the state Department of Transportation related projects, we may not receive any of these earn out payments. While the buyer of the state Department of Transportation related projects has indemnified us for all contracts and liabilities sold, and has agreed to issue a standby letter of credit in our favor in February 2008 to cover any remaining exposure, if the buyer were unable to meet its contractual obligations to a customer and the surety paid the amounts due under the bond, the surety would seek reimbursement of such amounts from us. The closing was effective February 1, 2007 to the extent set forth in the purchase agreement. As a result of this sale, we recorded an impairment charge of $44.5 million during the year ended December 31, 2006 calculated using the estimated sales price and management’s estimate of closing costs and other liabilities. In connection with the execution of the sales agreement in the first quarter of 2007, we recorded an additional $2.9 million charge in connection with this transaction.

     During the fourth quarter of 2004, we ceased performing new services in the network services operations. On May 24, 2006, we sold certain of these network services operations assets to a third party for $0.2 million consisting of $0.1 million in cash and a promissory note in the principal amount of $0.1 million. The promissory note is included in other current assets in the accompanying condensed unaudited consolidated balance sheet. These operations have been classified as a discontinued operation in all periods presented. The net income for the network services operations was immaterial for both the three and six months ended June 30, 2007 and 2006, respectively.

Note 8 — Commitments and Contingencies

     We contracted to construct a natural gas pipeline for Coos County, Oregon in 2003. Construction work on the pipeline ceased in December 2003 after the County refused payment due on regular contract invoices of $6.3 million and refused to process change orders submitted to the County on or after November 29, 2003 for additional work. In February 2004, we declared a breach of contract and brought an action for breach of contract against Coos County in Federal District Court in Oregon, seeking payment for work done, interest and anticipated profits. In April 2004, Coos County announced it was terminating the contract and seeking another company to complete the project. Coos County subsequently counterclaimed against us in the Federal District Court action seeking significant damages for breach of contract for alleged failures to properly construct the pipeline and for alleged environmental and labor law violations, and other causes. The amount of revenue recognized on the Coos County project that remained uncollected in accounts receivable on the June 30, 2007 balance sheet amounted to $6.3 million representing amounts due to us on normal progress payment invoices submitted under the contract. In addition to these uncollected receivables, we also have additional claims for payment and interest in excess of $6.0 million, including all of our change order billings and retainage, which we have not recognized as revenue but which we believe are due to us under the terms of the contract. The matter is currently being prepared for trial, expected during 2008. We have incurred substantial costs in connection with this claim and will continue to do so until the resolution of the matter. The outcome of the matter is uncertain and an unfavorable outcome could have a material adverse effect on our results of operations, however, we believe we will recover the uncollected receivable.

     In connection with the Coos County pipeline project, the United States Army Corps of Engineers, or “Corps of Engineers”, and the Oregon Department of Environmental Quality issued cease and desist orders and notices of non-compliance to Coos County and to us with respect to the County’s project. While we do not agree that the notices were appropriate or justified, we have cooperated with the Corps of Engineers and the Oregon Division of State Land, Department of Environmental Quality to mitigate any adverse impact as a result of construction. Through December 31, 2005 mitigation efforts have cost MasTec approximately $1.4 million. These costs were included in the costs on the project at December 31, 2005 and December 31, 2004. No further mitigation expenses were incurred in 2006 or are anticipated. On March 30, 2006, the Corps of Engineers brought a complaint in a federal district court against us and the County and are seeking significant damages. The matter is expected to go to trial in the fall of 2007. We are contesting this action vigorously, but can provide no assurance that a favorable outcome will be

reached. The outcome of the matter is uncertain and an unfavorable outcome could have a material adverse effect on our results of operations.

     We have a $0.1 million accrued liability in our unaudited consolidated balance sheet as of June 30, 2007 relating to all unresolved Coos County matters and unpaid settlements reached described above.

Note 9 — Concentrations of Risk

     We provide services to our customers in the following industries: communications, utilities and government.

     Revenue for customers in these industries is as follows (in thousands):

	$	256,284	$	230,516	$	497,280	$	448,124

     We grant credit, generally without collateral, to our customers. Consequently, we are subject to potential credit risk related to changes in business and economic factors. However, we generally have certain lien rights on that work and concentrations of credit risk are limited due to the diversity of the customer base. We believe our billing and collection policies are adequate to minimize potential credit risk. During the three months ended June 30, 2007, 53.4% of our total revenue was attributed to two customers. Revenue from these two customers accounted for 42.7% and 10.7%, respectively, of the total revenue for the three months ended June 30, 2007. During the three months ended June 30, 2006, two customers accounted for 46.2% of our total revenue. Revenue from these two customers accounted for 34.2% and 12.0%, respectively, of the total revenue for the three months ended June 30, 2006. During the six months ended June 30, 2007, 54.5% of our total revenue was attributed to two customers. Revenue from these two customers accounted for 44.1% and 10.4%, respectively, of the total revenue for the six months ended June 30, 2007. During the six months ended June 30, 2006, two customers accounted for 49.2% of our total revenue. Revenue from these two customers accounted for 36.1% and 13.1%, respectively, of the total revenue for the six months ended June 30, 2006.

     We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of customers to make required payments. We maintain an allowance for doubtful accounts of $8.9 million and $11.6 million as of June 30, 2007 and December 31, 2006, respectively, for both specific customers and as a reserve against other uncollectible accounts receivable. The decrease in reserves is due to certain specific reserves being written off against the receivable in the six months ended June 30, 2007. Management analyzes historical bad debt experience, customer concentrations, customer credit-worthiness, the availability of liens, the existence of payment bonds and other sources of payment, and current economic trends when evaluating the adequacy of the allowance for doubtful accounts. If judgments regarding the collectibility of accounts receivables are incorrect, adjustments to the allowance may be required, which would reduce profitability. In addition, our reserve covers the accounts receivable related to customers that filed for bankruptcy protection. As of June 30, 2007 and December 31, 2006, we had remaining receivables from customers undergoing bankruptcy reorganization totaling $9.9 million, of which $4.4 million is specifically reserved. Based on the analytical process described above, management believes that we will recover the net amounts recorded. Should additional customers file for bankruptcy or experience financial difficulties, or should anticipated recoveries in existing bankruptcies and other workout situations fail to materialize, we could experience reduced cash flows and losses in excess of the current allowance.

MasTec, Inc.
Notes to the Condensed Unaudited Consolidated Financial Statements

Note 10 — Related Party Transactions

     MasTec purchases, rents and leases equipment used in its business from a number of different vendors, on a non-exclusive basis, including Neff Corp. (“Neff”), in which Jorge Mas, Chairman of our Board of Directors, and Jose Mas, our President and Chief Executive Officer, were directors and owners of a controlling interest through June 4, 2005. Juan Carlos Mas, the brother of Jorge and Jose Mas, was the Chairman, Chief Executive Officer, a director and a shareholder of Neff until May 31, 2007 when he sold his Neff shares and resigned as its chief executive officer. Juan Carlos Mas remains as chairman of the Neff board of directors. During the three months ending June 30, 2007 and 2006, we paid Neff approximately $0.5 million and $0.2 million, respectively, and $0.9 million and $0.4 million during the six months ended June 30, 2007 and 2006, respectively. We believe the amounts paid to Neff was equivalent to the payments that would have been made between unrelated parties for similar transactions acting on an at arms length basis.

     We provide the services of certain marketing and sales personnel to an entity which was previously 49% owned by us. These services are reimbursed to us at cost. During the six months ended June 30, 2007, total payments received from this entity amounted to approximately $1.1 million.

     We charter aircrafts from a third party who leases two of its aircraft from entities in which Jorge Mas, Chairman of our Board of Directors, and Jose Mas, our President and Chief Executive Officer, have an ownership interest. We paid this unrelated chartering company approximately $0.2 million and $0.6 million during the three and six month period ended June 30, 2007, respectively, and $0.1 million and $0.2 million during the three and six month period ended June 30, 2006, respectively.

     During the three month period ended June 30, 2007 and 2006, we had an arrangement with a customer whereby we leased employees to the customer and charged approximately $0.1 million and $0.1 million, respectively, to the customer. We leased employees to this customer and charged approximately $0.2 million and $0.2 million during the six month period ended June 30, 2007 and 2006, respectively. Jorge Mas, Chairman of our Board of Directors, and Jose Mas, our President and Chief Executive Officer, are minority owners of this customer.

     MasTec has entered into split dollar agreements with key executives and former executives, and with the Chairman of our Board of Directors. During the three months ended June 30, 2007 and 2006, we paid approximately $0.3 million and $0.3 million, respectively, in premiums in connection with these split dollar agreements and approximately $0.5 million and $0.6 million during the six month period ended June 30, 2007 and 2006, respectively.

     In December 2006, we sold a property used in our operations for $3.5 million to an entity whose principal is also a principal of our 51% owned subsidiary. We have received a note in the amount of $2.8 million due December 2007, and guaranteed by the principal noted above. Concurrent with the sale of this property, we entered into a month-to-month lease agreement at $25,000 per month. In the second quarter of 2007 we terminated this lease. In accordance with Statement of Financial Accounting Standards No. 66, “Accounting for Sales of Real Estate” and Statement of Financial Accounting Standards No. 98, “Accounting for Leases; Sale-Leaseback Transactions Involving Real Estate; Sales-Type Leases of Real Estate; Definition of the Lease Term; Initial Direct Costs of Direct Financing Lease-An Amendment of FASB Statements No. 13, 66 and 91 and a Rescission of FASB Statement No. 26 and Technical Bulletin No. 79-11,” we recognized a gain on this sale of approximately $2.5 million in the first quarter of 2007.

Note 11 — New Accounting Pronouncements

     On February 15, 2007, the FASB issued Statement of Financial Accounting Standards No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities — Including an Amendment of FASB Statement No. 115” (“SFAS 159”). This standard permits an entity to measure financial instruments and certain other items at estimated fair value. Most of the provisions of SFAS No. 159 are elective; however, the amendment to SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” applies to all entities that own trading and available-for-sale securities. The fair value option created by SFAS 159 permits an entity to measure eligible items at fair value as of specified election dates. The fair value option (a) may generally be applied instrument by instrument, (b) is irrevocable unless a new election date occurs, and (c) must be applied to the entire instrument and not to only a portion of the instrument. SFAS 159 is effective as of the beginning of the first fiscal year that begins after November 15, 2007. Early adoption is permitted as of the beginning of the previous fiscal year provided that the entity (i) makes that choice in the first 120 days of that year, (ii) has not yet issued financial statements for any interim period of such year, and (iii) elects to apply the provisions of SFAS 157. We are currently evaluating the impact of SFAS 159, if any, on our consolidated financial statements.

MasTec, Inc.
Notes to the Condensed Unaudited Consolidated Financial Statements

     In November 2006, the Emerging Issues Task Force reached a consensus on Issue No. 06-04, “Accounting for Deferred Compensation and Postretirement Benefit Aspects of Endorsement Split of Endorsement Split-Dollar Life Insurance Arrangements”, (“EITF 06-04”). EITF 06-04 reached a consensus that for a split-dollar life insurance arrangement that provides a benefit to an employee that extends to postretirement periods, an employer should recognize a liability for future benefits in accordance with FAS No. 106 or Opinion 12 (depending upon whether a substantive plan is deemed to exist) based on the substantive agreement with the employee. This consensus is effective for fiscal years beginning after December 15, 2007. We are currently evaluating the impact of EITF 06-04, if any, on our consolidated financial statements.

     In November 2006, the Emerging Issues Task Force reached a consensus on Issue No. 06-05, “Accounting for Purchase of Life Insurance-Determining the Amount That Could Be Realized in Accordance with FASB Technical Bulletin No. 85-04”, (“EITF 06-05”). EITF 06-05 reached a consensus that a policyholder should consider any additional amounts included in the contractual terms of the policy in determining the amount that could be realized under the insurance contract. The Task Force agreed that contractual limitations should be considered when determining the realizable amounts. Those amounts that are recoverable by the policyholder at the discretion of the insurance company should be excluded from the amount that could be realized. The Task Force also agreed that fixed amounts that are recoverable by the policyholder in future periods in excess of one year from the surrender of the policy should be recognized at their present value. The Task Force also reached a consensus that a policy holder should determine the amount that could be realizable under the life insurance contract assuming the surrender of an individual-life by individual policy (or certificate by certificate in a group policy). The Task Force noted that any amount that is ultimately realized by the policyholder upon the assumed surrender of the final policy (or final certificate in a group policy) shall be included in the amount that could be realized under the insurance contract. This consensus is effective for fiscal years beginning after December 15, 2006. The implementation of this pronouncement did not have a material effect on our consolidated financial statements.

     In September 2006, the FASB issued Statement of Financial Accounting Standards No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an amendment of FASB Statements No. 87, 88 and 132(R)” (“SFAS 158”). This statement requires an employer to recognize the funded status of a benefit plan as an asset or liability in its financial statements. The funded status is measured as the difference between plan assets at fair value and the plan’s specific benefit obligation, which would be the projected benefit obligation. Under SFAS 158, the gains or losses and prior service cost or credits that arise in a period but are not immediately recognized as components of net periodic benefit expense will now be recognized, net of tax, as a component of other comprehensive income. SFAS 158 is effective for fiscal years ending after December 15, 2008. We do not expect this pronouncement to have a material effect on our consolidated financial statements.

     In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (“SFAS 157”), “Fair Value Measurements”. This statement establishes a single authoritative definition of fair value, sets out a framework for measuring fair value, and requires additional disclosures about fair-value measurements. SFAS 157 defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date”. For MasTec, SFAS 157 is effective for the fiscal year beginning January 1, 2008. We are currently evaluating this standard to determine its impact, if any, on our consolidated financial statements.

     In February 2006, the FASB issued Statement of Financial Accounting Standard No. 155, “Accounting for Certain Hybrid Financial Instruments — an amendment of FASB Statements No. 133 and 140.” In March 2006, the FASB issued Statement of Financial Accounting Standard No. 156, “Accounting for Servicing of Financial Assets — an amendment of FASB Statement No. 140.” These statements became effective January 1, 2007 and did not have a material effect on our consolidated financial statements.

Other significant changes to the credit facility resulting from this amendment include:

• An accordion feature was added which allows us to request an increase in the maximum amount borrowed under the Credit Facility from $150.0 million to $200.0 million, if certain criteria under the Credit Facility is met.

• The maximum margin applied to the bank’s base rate was reduced from 0.75% to 0.50%.

• The maximum margin applied to the LIBOR-based loans was reduced from 2.25% to 2.00%, and no higher than 1.125% through December 31, 2007.

• The maximum unused line fee was reduced from 0.375% to 0.25%.

• The net availability amount below which we must be in compliance with a fixed charge ratio covenant of 1.1 to 1.0 decreased from $20.0 million to $15.0 million (subject to adjustment if the maximum amount we may borrow under the Credit Facility is adjusted).

     We are obligated to pay a fee of $0.2 million in connection with this amendment to our Credit Facility.

Overview

     We are a leading specialty contractor operating mainly throughout the United States and across a range of industries. Our core activities are the building, installation, maintenance and upgrade of communications and utility infrastructure. Our primary customers are in the following industries: communications (including satellite television and cable television), utilities and government. We provide similar infrastructure services across the industries we serve. Our customers rely on us to build and maintain infrastructure and networks that are critical to their delivery of voice, video and data communications, electricity and other energy resources.

     On March 30, 2007, our board of directors voted to sell substantially all of our Canadian assets and liabilities. On April 10, 2007, we sold substantially all of our Canadian net assets for approximately $1.0 million. The purchase price is subject to adjustments based on the value of the net assets acquired as of March 31, 2007. As a result of our decision to sell substantially all of our Canadian net assets, we wrote-off approximately $0.4 million in goodwill and recorded a non-cash impairment charge of approximately $0.2 million during the three month period ended March 31, 2007. See Note 7 in Part I. Item 1. Financial Statements.

     On February 14, 2007, we sold substantially all of our state Department of Transportation related projects and underlying net assets. We kept certain assets and liabilities related to the state Department of Transportation projects. See “Item 1A. Risk Factors — We have agreed to keep certain assets and liabilities related to the state Department of Transportation related projects that were sold in February 2007” included in our most recent Annual Report on Form 10-K. A sales price of $1.0 million was paid at closing. In addition, the buyer is required to pay us an earn out of up to $12.0 million contingent on the future operations of the projects sold to the buyer. However, as the earn out is contingent upon the future performance of the state Department of Transportation related projects, we may not receive any of these earn out payments. See Note 7 in Part I. Item 1. Financial Statements.

     Effective February 1, 2007, we acquired the remaining 51% equity interest in DirectStar, an investment which had been previously accounted for by the equity method. As a result of our acquisition of the remaining 51% equity interest, we have consolidated the operations of this entity with our results beginning in February 2007. See Note 4 in Part I. Item 1. Financial Statements.

     On January 31, 2007, we issued $150.0 million aggregate principal amount of 7.625% senior notes due February 2017. The notes are guaranteed by substantially all of our domestic restricted subsidiaries. We used approximately $121.8 million of the net proceeds from this offering to redeem all of our 7.75% senior subordinated notes due February 2008 plus interest. We expect to use the remaining net proceeds for working capital, possible acquisition of assets and businesses and other general corporate purposes.

Revenue

     We provide services to our customers which are companies in the communications and utilities industries, as well as government customers.

     Revenue for customers in these industries is as follows (in thousands):

	For the Three Months Ended				For the Six Months Ended
	June 30,				June 30,
	2007		2006		2007		2006
Communications	$	189,530	$	163,243	$	367,700	$	318,887
Utilities		51,702		59,462		103,395		114,226
Government		15,052		7,811		26,185		15,011
	$	256,284	$	230,516	$	497,280	$	448,124

     A majority of our revenue is derived from projects performed under service agreements. Some of these agreements are billed on a time and materials basis and revenue is recognized as the services are rendered. We also provide services under master service agreements which are generally multi-year agreements. Certain of our master service agreements are exclusive up to a specified dollar amount per work order for each defined geographic area. Work performed under master service and other agreements is typically generated by work orders, each of which is performed for a fixed fee. The majority of these services typically are of a maintenance nature and to a lesser extent upgrade services. These master service agreements and other service agreements are frequently awarded on a competitive bid basis, although customers are sometimes willing to negotiate contract extensions beyond their original terms without re-bidding. Our master service agreements and other service agreements have various terms, depending upon the nature of the services provided and are typically subject to termination on short notice. Under our master service and similar type service agreements, we furnish various specified units of service each for a separate fixed price per unit of service. We recognize revenue as the related unit of service is performed. For service agreements on a fixed fee basis, profitability will be reduced if the actual costs to complete each unit exceed original estimates. We also immediately recognize the full amount of any estimated loss on these fixed fee projects if estimated costs to complete the remaining units for the project exceed the revenue to be received from such units.

     The remainder of our work is generated pursuant to contracts for specific installation and construction projects or jobs. For installation/construction projects, we recognize revenue on the units-of-delivery or percentage-of-completion methods. Revenue on unit based projects is recognized using the units-of-delivery method. Under the units-of-delivery method, revenue is recognized as the units are completed at the contractually agreed price per unit. For certain customers with unit based installation and construction projects, we recognize revenue after the service is performed and the work orders are approved to ensure that collectibility is probable from these customers. Revenue from completed work orders not collected in accordance with the payment terms established with these customers is not recognized until collection is assured. Revenue on non-unit based contracts is recognized using the percentage-of-completion method. Under the percentage-of-completion method, we record revenue as work on the contract progresses. The cumulative amount of revenue recorded on a contract at a specified point in time is that percentage of total estimated revenue that incurred costs to date bear to estimated total contract costs. Customers are billed with varying frequency: weekly, monthly or upon attaining specific milestones. Such contracts generally include retainage provisions under which 2% to 15% of the contract price is withheld from us until the work has been completed and accepted by the customer. If, as work progresses, the actual costs of a project exceed estimates, the profit recognized on revenue from that project decreases. We recognize the full amount of any estimated loss on a contract at the time the estimates indicate such a loss.

22

     Revenue by type of contract is as follows (in thousands):

	For the Three Months Ended				For the Six Months Ended
	June 30,				June 30,
	2007		2006		2007		2006
Master service and other service agreements	$	183,934	$	171,411	$	365,738	$	341,275
Installation/construction projects agreements		72,350		59,105		131,542		106,849
	$	256,284	$	230,516	$	497,280	$	448,124

Costs of Revenue

     Our costs of revenue include the costs of providing services or completing the projects under our contracts including operations payroll and benefits, fuel, subcontractor costs, equipment leases and rental, materials not provided by our customers, and insurance. Profitability will be reduced if the actual costs to complete each unit exceed original estimates on fixed price service agreements. We also immediately recognize the full amount of any estimated loss on fixed fee projects if the estimated costs to complete the remaining units for the project exceed the revenue to be received from such units.

     Our customers generally supply materials such as cable, conduit and telephone equipment. Customer furnished materials are not included in revenue and cost of sales because such materials are purchased by the customer. The customer determines the specifications of the materials that are to be utilized to perform installation/construction services. We are only responsible for the performance of the installation/construction services and not the materials for any contract that includes customer furnished materials nor do we have any risk associated with customer furnished materials. Our customers retain the financial and performance risk of all customer furnished materials.

General and Administrative Expenses

     General and administrative expenses include all costs of our management and administrative personnel, provisions for bad debts, rent, utilities, travel, business development efforts and back office administration such as financial services, insurance, administration, professional costs and clerical and administrative overhead.

Discontinued Operations

     In March 2007, we declared our Canadian operations a discontinued operation due to our decision to sell this operation. Accordingly, results of operations for all periods presented of our Canadian operations have been classified as discontinued operations and all financial information for all periods presented reflects these operations as discontinued operations. On April 10, 2007, we sold substantially all of our Canadian assets and liabilities. See Note 7 in Part I. Item 1. Financial Statements.

     In December 2005, we declared our state Department of Transportation related projects and assets a discontinued operation due to our decision to sell substantially all these projects and assets. Accordingly, results of operations for all periods presented of substantially all of our state Department of Transportation related projects and assets have been classified as discontinued operations and all financial information for all periods presented reflects these operations as discontinued operations. On February 14, 2007, we sold our state Department of Transportation related projects and net assets. See Note 7 in Part I. Item 1. Financial Statements.

Critical Accounting Policies and Estimates

     Our discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the amounts reported in our financial statements and the accompanying notes. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, intangible assets, reserves and accruals, impairment of assets, income taxes, insurance reserves and litigation and contingencies. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. As management estimates, by their nature, involve judgment regarding future uncertainties, actual results may differ materially from these estimates. Refer to Note 3 to our condensed consolidated financial statements of this Quarterly Report on Form 10-Q and to our most recent Annual Report on Form 10-K for further information regarding our critical accounting policies and estimates.

23

Litigation and Contingencies

     Litigation and contingencies are reflected in our condensed unaudited consolidated financial statements based on our assessments of the expected outcome. If the final outcome of any litigation or contingencies differs significantly from our current expectations, a charge to earnings could result. See Note 8 to our condensed unaudited consolidated financial statements in Part I. Item 1. and Part II. Item 1. to this Form 10-Q for updates to our description of legal proceedings and commitments and contingencies.

Comparison of Quarterly Results

     The following table reflects our consolidated results of operations in dollar and percentage of revenue terms for the periods indicated. This table includes the reclassification for the three months and six months ended June 30, 2006 of the net loss for our Canadian operations to discontinued operations from the prior period presentation (in thousands):

Three Months Ended June 30, 2007 Compared to Three Months Ended June 30, 2006

     Revenue. Our revenue was $256.3 million for the three months ended June 30, 2007, compared to $230.5 million for the same period in 2006, representing an increase of $25.8 million or 11.2%. This increase was due primarily to increased revenue of approximately $30.5 million from DIRECTV^®. The DIRECTV^® increase was primarily due to subscriber activations from the February 2007 DirectStar acquisition and, also, a significant increase in the number of DIRECTV^® installation and service work orders. Revenue also increased due to higher revenue of $8.9 million from Verizon due to additional work orders. In addition, revenue related to projects for the South Florida Water Management District increased by $3.6 million in the three months ended June 30, 2007 to $6.3 million as we received increased work volume from this customer. These increases in revenue were partially offset by a decrease in revenue of $11.2 million from AT&T (formerly BellSouth) and $3.4 million from Florida Power & Light.

     Costs of Revenue. Our costs of revenue were $213.3 million or 83.2% of revenue for the three months ended June 30, 2007, compared to $196.7 million or 85.3% of revenue for the same period in 2006. The $16.6 million increase in costs of revenue is primarily attributed to the increase in revenue discussed above. The improvement in operating margin is mainly attributed to a reduction in payroll costs and contract labor costs from 54.8% of revenue to 50.9% of revenue. The improvement in operating margin was helped by an improvement in the mix of projects including the acquisition of DirectStar. Offsetting this improvement in margin is an increase in fuel costs as a percent of revenue, from 3.8% of revenue in the three months ended June 30, 2006 to 4.1% of revenue in the comparable period in 2007 (associated with higher average fuel costs), as well as other individually small margin changes on other “cost of revenue” line items.

     Depreciation. Depreciation was $4.1 million for the three months ended June 30, 2007, compared to $3.5 million for the same period in 2006, representing an increase of $0.6 million. The increase in depreciation expense in the three

months ended June 30, 2007 was due primarily to our increase in capital expenditures resulting from our entering into capital leases for our fleet requirements. As a percentage of revenue, depreciation expense was relatively consistent over both periods, representing 1.6% of revenue in the three months ended June 30, 2007 and 1.5% of revenue in the three months ended June 30, 2006.

     General and administrative expenses. General and administrative expenses were $20.2 million or 7.9% of revenue for the three months ended June 30, 2007, compared to $17.0 million or 7.4% of revenue for the same period in 2006, representing an increase of $3.2 million. We recorded $1.2 million of additional bad debt expense in the three months ended June 30, 2007 as compared to the three months ended June 30, 2006. This increase is largely associated with higher levels of revenue and our evaluation of the collectibility of our accounts receivable. $1.3 million of the increase is due to an increase in compensation in the quarter ended June 30, 2007 as compared to the three months ended June 30, 2006. In addition, insurance costs increased by $0.9 million in the three months ended June 30, 2007 as compared to the same period in 2006, due to a number of factors including larger business volume.

     Interest expense, net. Interest expense, net of interest income was $2.1 million or 0.8% of revenue for the three months ended June 30, 2007, compared to $2.4 million or 1.0% of revenue for the same period in 2006 representing a decrease of approximately $0.25 million. The decrease was due in part to higher interest income, which increased from $1.4 million in second quarter of 2006 to $1.5 million in second quarter of 2007, largely due to higher outstanding cash balances. We also experienced an increase in interest expense on notes of $0.5 million resulting from an increase in average long term debt outstanding in the three months ended June 30, 2007 as compared to the same period in 2006. This was largely offset by a $0.5 million reduction in expense associated with the amortization of deferred financing costs in the three months ended June 30, 2007 as compared to the same period in 2006.

     Other income (expense), net. Other income, net was $0.6 million for the three months ended June 30, 2007, compared to $1.6 million in the three months ended June 30, 2006, representing a decrease of $1.1 million. The decrease is mainly attributed to approximately $1.2 million recognized during the three months ended June 30, 2006 on our equity income related to our previously owned 49% interest in an equity-method investment. As discussed in Note 3 and Note 4 to our condensed unaudited consolidated financial statements in Part I. Item 1 of this Form 10-Q, effective February 1, 2007, we acquired the remaining 51% interest and consolidated the results of this entity. As such, beginning February 1, 2007, there is no equity income recorded for this investment as their results of operations are consolidated within our own.

     Minority interest. Minority interest for GlobeTec Construction, LLC (“GlobeTec”) resulted in a charge of $1.0 million for the three months ended June 30, 2007, compared to a charge of $0.3 million for the same period in 2006, representing an increase in minority interest charge of $0.7 million as a result of higher net income in the three months ended June 30, 2007 compared to the same period in 2006.

     Discontinued operations. The loss on discontinued operations, which includes our Brazilian operations, our network services operations, our state Department of Transportation related projects and assets, as well as our Canadian operations was $0.2 million for the three months ended June 30, 2007 compared to a loss of $36.0 million for the three months ended June 30, 2006. The net loss for our state Department of Transportation related projects and assets amounted to $0 million for the three months ended June 30, 2007 compared to a net loss of $35.7 million for the three months ended June 30, 2006. Effective February 1, 2007, we sold our state Department of Transportation related projects and underlying assets. Therefore, the results of operations for our state Department of Transportation related projects and assets during the three month period ended June 30, 2006 are included as a component of discontinued operations while there was no effect during the three months during the comparable period in 2007. In addition, the net loss attributed to our Canadian operations was $0.2 million during the three month period ended June 30, 2007 compared to $0.2 million during the three month period ended June 30, 2006. In our other discontinued operations, during the three months ended June 30, 2007 we had no net loss compared to a net loss of $47,000 during the comparable period in 2006.

Six Months Ended June 30, 2007 Compared to Six Months Ended June 30, 2006

     Revenue. Our revenue was $497.3 million for the six months ended June 30, 2007, compared to $448.1 million for the same period in 2006, representing an increase of $49.2 million or 11.0%. This increase was due primarily to increased revenue of approximately $57.8 million from DIRECTV^®. The DIRECTV^® increase was primarily due to subscriber activations from the February 2007 DirectStar acquisition and, also, a significant increase in the number of DIRECTV^® installation and service work orders. Revenue also increased due to higher revenue of $16.8 million from Verizon due to a higher volume of work orders. In addition, revenue related to projects for the South Florida Water Management District increased by $5.8 million to $10.0 million as we received increased work volume from this customer. These increases in revenue were partially offset by a decrease in revenue of $24.9 million from AT&T (formerly BellSouth) and $6.9 million from Florida Power & Light.

     Costs of Revenue. Our costs of revenue were $424.3 million or 85.3% of revenue for the six months ended June 30, 2007, compared to $387.5 million or 86.5% of revenue for the same period in 2006. The $36.9 million increase in costs of revenue is primarily attributed to the increase in revenue discussed above. The improvement in operating margin is mainly attributed to a reduction in payroll and contract labor costs from 54.9% of revenue to 52.0% of revenue. The improvement in operating margin was helped by an improvement in the mix of projects including the acquisition of DirectStar. Offsetting this improvement in margins is an increase in the cost of fuel as a percent of revenue, from 3.5% of revenue in the six months ended June 30, 2006 to 3.8% of revenue in the comparable period in 2007; this increase is associated with higher average fuel costs. We also experienced an increase in the cost of materials we use, from 13.0% of revenue in the first half of 2006 to 13.3% of revenue in the six months ended June 30, 2007, as well as several individually smaller increases in costs of revenue.

     Depreciation. Depreciation was $7.9 million for the six months ended June 30, 2007, compared to $7.0 million for the same period in 2006, representing an increase of $0.9 million. The increase in depreciation expense in the six months ended June 30, 2007 was due primarily to our increase in capital expenditures resulting from our entering into capital leases for our fleet requirements. As a percentage of revenue, depreciation expense was relatively consistent over both periods, representing 1.6% of revenue in the six months ended June 30, 2007 and 2006.

     General and administrative expenses. General and administrative expenses were $39.5 million or 7.9% of revenue for the six months ended June 30, 2007, compared to $33.1 million or 7.4% of revenue for the same period in 2006, representing an increase of $6.4 million. We recorded $2.0 million of additional bad debt expense in the six months ended June 30, 2007 as compared to the same period in 2006. This is largely associated with higher levels of revenue and our evaluation of the collectibility of our accounts receivable. $2.3 million of the increase is due to an increase in compensation costs in the six months ended June 30, 2007 as compared to the six months ended June 30, 2006. The increase in general and administrative expenses was also due to additional legal and professional fees, which increased by approximately $0.8 million to $6.9 million during the six month period ended June 30, 2007 compared to the same period in 2006.

     Interest expense, net. Interest expense, net of interest income was $4.9 million or 1.0% of revenue for the six months ended June 30, 2007, compared to $5.9 million for the same period in 2006, representing a decrease of approximately $1.0 million. The decrease was due in part to higher interest income, which increased from $2.5 million in the six months ended June 30, 2006 to $4.2 million in comparable period of 2007, largely due to higher outstanding cash balances. Offsetting this increase in interest income was an increase in interest expense on notes of $0.7 million resulting from an increase in average long term debt outstanding in the six months ended June 30, 2007 as compared to the same period in 2006.

     Other income (expense), net. Other income, net was $4.1 million for the six months ended June 30, 2007, compared to $1.9 million in the six months ended June 30, 2006, representing an increase of $2.2 million. The increase is largely attributed to an increase of $3.3 million on the sale of property and equipment, which increased to $3.7 million in the six months ended June 30, 2007. $2.5 million of this increase is due to the sale of property discussed in Note 10 to our condensed unaudited consolidated financial statements in Part I. Item 1. Financial Statements to this Form 10-Q. Offsetting this is a decrease of $1.5 million in the amount of equity income recognized during the six months ended June 30, 2007 from our interest in an equity-method investment. As discussed in Note 3 and Note 4 to our condensed unaudited consolidated financial statements in Part I. Item 1. Financial Statements to this Form 10-Q, effective February 1, 2007, we acquired the remaining 51% interest and consolidated the results of this company. As such, beginning February 1, 2007, there is no equity income recorded for this entity as their results of operations are consolidated whereas in the six months ended June 30, 2006 we recorded $1.6 million in equity income.

26

     Minority interest. Minority interest for GlobeTec resulted in a charge of $1.7 million for the six months ended June 30, 2007, compared to $0.2 million for the same period in 2006, representing an increase in minority interest charge of $1.5 million as a result of higher net income in the six months ended June 30, 2007 compared to the same period in 2006.

     Discontinued operations. The loss on discontinued operations, which includes our Brazilian operations, our network services operations, our state Department of Transportation related projects and assets, as well as our Canadian operations was $5.5 million for the six months ended June 30, 2007 compared to a loss of $44.3 million for the six months ended June 30, 2006. The net loss for our state Department of Transportation related projects and assets amounted to $4.4 million for the six months ended June 30, 2007 compared to a net loss of $43.4 million for the six months ended June 30, 2006. Effective February 1, 2007, we sold our state Department of Transportation related projects and underlying assets. Therefore, the results of operations for our state Department of Transportation related projects and assets are only included for one month during the six month period ended June 30, 2007 compared to six months during the comparable period in 2006. Furthermore, the loss from our state Department of Transportation related projects and assets, includes a loss of $2.9 million in connection with the execution of the sales agreement during the first quarter of 2007. In addition, the net loss attributed to our Canadian operations was $1.1 million during the six month period ended June 30, 2007 compared to $0.7 million during the six month period ended June 30, 2006. In our other discontinued operations, during the six months ended June 30, 2007 we had a net income of $8,000 compared to a net loss of $0.2 million during the comparable period in 2006.

Financial Condition, Liquidity and Capital Resources

     Our primary sources of liquidity are cash flows from continuing operations, availability under our credit facility, capital lease arrangements, and proceeds from sales of assets and investments. On January 31, 2007, we also issued $150.0 million of 7.625% senior notes due February 2017. On March 2, 2007, we used $121.8 million of the proceeds from the senior note offering to redeem all of our remaining 7.75% senior subordinated notes plus interest. In February 2007, we used $15.0 million in connection with the acquisition of the remaining 51% equity interest in an investment in which we previously owned a 49% interest. The remaining net proceeds from the senior note offering will be used for working capital, possible acquisitions of assets and businesses and other general corporate purposes. On January 24, 2006, we completed a public offering of 14,375,000 shares of our common stock at $11.50 per share. The net proceeds from the sale were approximately $156.5 million after deducting underwriting discounts and offering expenses. We used $18.5 million of the net proceeds for the cash portion of the purchase price of substantially all of the assets and contracts of Digital Satellite Services, Inc., which we refer to as the DSSI acquisition. On March 2, 2006, we used $75.5 million of the net proceeds of the public offering to redeem a portion of our 7.75% senior subordinated notes due February 2008, including the payment of related interest.

     Our primary liquidity needs are for working capital, capital expenditures, insurance collateral in the form of cash and letters of credit, equity investment and earn out obligations and debt service. In January 2006, our lenders issued a $6.5 million letter of credit to our insurance carrier related to our 2006 insurance plans. In November 2006, our lenders issued an $18.0 million letter of credit to our insurance carrier related to our current insurance plans simultaneously with the insurance carrier returning cash collateral of $18.0 million plus all accrued interest to us. Following the January 2007 issuance of the $150.0 million senior notes due 2017, our semi-annual interest payments have been increased to approximately $5.7 million for the senior notes from approximately $4.7 million. In addition to ordinary course working capital requirements, we estimate that we will spend between $20.0 million to $40.0 million per year on capital expenditures. We will, however, because of our improved financial condition, continue to evaluate lease versus buy decisions to meet our equipment needs and based on this evaluation, our capital expenditures may increase in 2007 from this estimate. We expect to continue to sell older vehicles and equipment as we upgrade with new equipment and we expect to obtain proceeds from these sales. In addition, in connection with certain acquisitions including the DSSI acquisition and our acquisition of the remaining 51% equity interest in our equity investment described below, we have agreed to pay the sellers certain equity investment and earn out obligations which are generally based on the future performance of the investment or acquired business.

     As discussed above, effective February 1, 2007, we acquired the remaining 51% equity interest in an investment in which we had previously owned 49%. We paid the seller $8.65 million in cash, in addition to approximately $6.35 million which we also paid at that time to discharge our remaining obligations to the seller under the purchase agreement for the original 49% equity interest. We also issued to the seller 300,000 shares of our common stock. We agreed to pay

27

the seller an earn out through the eighth anniversary of the closing date based on the future performance of the acquired entity. In connection with the purchase, we entered into a service agreement with the sellers to manage the business. Under certain circumstances, including a change of control of MasTec or the acquired entity or in certain cases a termination of the service agreement, the remaining earn out payments will be accelerated and become payable. Under the purchase agreement, we may be required to invest up to an additional $3.0 million in this entity.

     We need working capital to support seasonal variations in our business, primarily due to the impact of weather conditions on external construction and maintenance work, including storm restoration work, and the corresponding spending by our customers on their annual capital expenditure budgets. Our business is typically slower in the first and fourth quarters of each calendar year and stronger in the second and third quarters. Accordingly, we generally experience seasonal working capital needs from approximately April through September to support growth in unbilled revenue and accounts receivable, and to a lesser extent, inventory. Our billing terms are generally net 30 to 60 days, although some contracts allow our customers to retain a portion (from 2% to 15%) of the contract amount until the contract is completed to their satisfaction. We maintain inventory to meet the material requirements of some of our contracts. Some of our customers pay us in advance for a portion of the materials we purchase for their projects, or allow us to pre-bill them for materials purchases up to a specified amount.

     Our vendors generally offer us terms ranging from 30 to 90 days. Our agreements with subcontractors usually contain a “pay-when-paid” provision, whereby our payments to subcontractors are made only after we are paid by our customers.

     We anticipate that funds generated from continuing operations, the net proceeds from our senior note offering completed in the first quarter of 2007, borrowings under our credit facility, and proceeds from sales of assets and investments will be sufficient to meet our working capital requirements, anticipated capital expenditures, insurance collateral requirements, equity investment obligations, letters of credit and debt service obligations for at least the next twelve months.

     As of June 30, 2007, we had $194.3 million in working capital compared to $164.0 million as of December 31, 2006. We define working capital as current assets less current liabilities. Cash and cash equivalents increased from $88.0 million at December 31, 2006 to $119.5 million at June 30, 2007 mainly due to net proceeds from our senior note offering.

     Net cash provided by operating activities was $27.3 million for the six months ended June 30, 2007 compared to $10.4 million for the six months ended June 30, 2006. The net cash provided by operating activities in the six months ended June 30, 2007 was primarily related to improved earnings and business mix (including the disposition of our state Department of Transportation business), as well as to the timing of cash payments to vendors and sources of cash from other assets and inventory management. The net cash provided in operating activities during the six months ended June 30, 2006 was primarily related to the timing of cash payments to vendors and sources of cash collections from customers, as well as the management of inventory and other assets.

     Net cash used in investing activities was $24.0 million for the six months ended June 30, 2007 compared to net cash used in investing activities of $30.8 million for the six months ended June 30, 2006. Net cash used in investing activities during the six months ended June 30, 2007 primarily related to $11.2 million used in connection with acquisitions made net of cash acquired and $14.8 million used for capital expenditures offset by $3.5 million in net proceeds from the sale of assets. Net cash used in investing activities during the six months ended June 30, 2006 primarily related to cash payments made in connection with the DSSI acquisition of $19.3 million, capital expenditures in the amount of $10.3 million and payments related to our equity investment in the amount of $2.8 million offset by $1.9 million in net proceeds from sales of assets.

     Net cash provided by financing activities was $27.2 million for the six months ended June 30, 2007 compared to $80.9 million for the six months ended June 30, 2006. Net cash provided by financing activities in the six months ended June 30, 2007 was mainly due to proceeds from the issuance of $150.0 million 7.625% senior notes in January 2007 partially offset by the redemption of $121.0 million 7.75% senior subordinated notes in February 2007 and $3.8 million in payments of financing costs. Net cash provided by financing activities in the six months ended June 30, 2006 was primarily related to net proceeds from the issuance of common stock of $156.5 million and proceeds from the issuance

28

of common stock pursuant to stock option exercises in the amount of $3.4 million partially offset by the redemption of $75.0 million principal on our senior subordinated notes and payments for borrowings of $3.8 million.

     Cash used in discontinued operations in the six months ended June 30, 2007 was $6.0 million. This mainly consisted of $6.2 million in cash used in operating activities, mostly attributed to our net loss from these operations.

     As discussed in Note 6 and Note 12 to our condensed unaudited consolidated financial statements in Part I. Item 1. Financial Statements to this Form 10-Q, we have a secured revolving credit facility for our operations which was amended and restated on July 31, 2007 with an effective date of June 30, 2007. The credit facility has a maximum amount of available borrowing of $150.0 million, subject to certain restrictions. If certain conditions under the Credit Facility are met, we may request that the maximum amount of available borrowing under the Credit Facility be increased from $150 million to $200 million. The costs related to this amendment were $0.2 million which are being amortized over the life of the credit facility. The credit facility expires on May 10, 2012. These deferred financing costs are included in prepaid expenses and other current assets and other assets in our consolidated balance sheet. On November 7, 2006, we amended our credit facility and provided our insurer with an $18 million letter of credit under the facility simultaneously with the insurer returning cash collateral of $18 million plus all accrued interest to us. As collateral for this letter of credit, we pledged $18 million to our lenders under the Credit Facility. This increase in the outstanding balance in letter of credit will not result in a reduction to our net availability under the credit facility as long as sufficient cash or collateral is granted to our lenders.

     The amount that we can borrow at any given time is based upon a formula that takes into account, among other things, eligible billed and unbilled accounts receivable, equipment, real estate and eligible cash collateral, which can result in borrowing availability of less than the full amount of the credit facility. As of June 30, 2007 and December 31, 2006, net availability under the credit facility, as amended, totaled $38.0 million and $35.1 million, respectively, which included outstanding standby letters of credit aggregating $90.7 million and $83.3 million in each period, respectively. At June 30, 2007, $69.1 million of the outstanding letters of credit were issued to support our casualty and medical insurance requirements. These letters of credit mature at various dates and most have automatic renewal provisions subject to prior notice of cancellation. The credit facility is collateralized by a first priority security interest in substantially all of our assets and a pledge of the stock of certain of our operating subsidiaries. Substantially all wholly-owned subsidiaries collateralize the facility. At June 30, 2007 and December 31, 2006, we had no outstanding cash draws under the credit facility. Interest under the credit facility accrues at rates based, at our option, on the agent bank’s base rate plus a margin of between 0.0% and 0.50%, or at the LIBOR rate (as defined in the credit facility) plus a margin of between 1.00% and 2.00%, depending on certain financial thresholds. The credit facility includes an unused facility fee of 0.25%.

     If the net availability under the credit facility is under $15.0 million on any given day, we are required to be in compliance with a minimum fixed charge coverage ratio measured on a monthly basis and certain events are triggered. The $15.0 million availability trigger is subject to adjustment if the maximum amount we may borrow under the credit facility is adjusted. The fixed charge coverage ratio is generally defined to mean the ratio of our net income before interest expense, income tax expense, depreciation expense, and amortization expense minus net capital expenditures and cash taxes paid to the sum of all interest expense plus current maturities of debt for the period. The financial covenant was not applicable as of June 30, 2007, because at that time net availability under the credit facility, as amended, exceeded the required threshold specified above.

     Based upon the amendments to the credit facility, our current availability, net proceeds from the sale of common stock, liquidity and projections for 2007, we believe we will be in compliance with the credit facility’s terms and conditions and the minimum availability requirements for the remainder of 2007. We are dependent upon borrowings and letters of credit under this credit facility to fund operations. Should we be unable to comply with the terms and conditions of the credit facility, we would be required to obtain modifications to the credit facility or another source of financing to continue to operate. We may not be able to achieve our 2007 projections and this may adversely affect our ability to remain in compliance with the credit facility’s minimum net availability requirements and minimum fixed charge ratio in the future.

     Our variable rate credit facility exposes us to interest rate risk. However, we had no cash borrowings outstanding under the credit facility at June 30, 2007.

29

     As of June 30, 2007, $150.0 million of our 7.625% senior notes due in February 2017, with interest due semi-annually were outstanding. The notes contain default (including cross-default) provisions and covenants restricting many of the same transactions as under our credit facility. The indenture which governs our senior notes allows us to incur the following additional indebtedness among others: the credit facility (up to $200 million), renewals to existing debt permitted under the indenture plus an additional $50 million of indebtedness, further indebtedness if our fixed charge coverage ratio is at least 2:1 for the four most recently ended fiscal quarters determined on a pro forma basis as if that additional debt has been incurred at the beginning of the period. In addition, the indenture prohibits incurring additional capital lease obligations in excess of 5% of our consolidated net assets at any time the senior notes remain outstanding. The definition of our fixed charge coverage ratio under the indenture is essentially equivalent to that under our credit facility.

     Some of our contracts require us to provide performance and payment bonds, which we obtain from a surety company. If we were unable to meet our contractual obligations to a customer and the surety paid our customer the amount due under the bond, the surety would seek reimbursement of such payment from us. At June 30, 2007, the cost to complete on our $271.8 million performance and payment bonds was $53.2 million.

New Accounting Pronouncements

     See Note 11 to our condensed unaudited consolidated financial statements in Part I. Item 1. Financial Statements to this Form 10-Q for certain new accounting pronouncements.

Seasonality

     Our operations are historically seasonally slower in the first and fourth quarters of the year. This seasonality is primarily the result of client budgetary constraints and preferences and the effect of winter weather on network activities. Some of our clients, 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.

Impact of Inflation

     The primary inflationary factor affecting our operations is increased labor costs. We are also affected by changes in fuel costs which increased significantly in 2007 and 2006.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     We are exposed to market risk related to changes in interest rates and fluctuations in foreign currency exchange rates. Our variable rate credit facility exposes us to interest rate risk. However, we had no cash borrowings under the credit facility at June 30, 2007.

Interest Rate Risk

     Less than 1% of our outstanding debt at June 30, 2007 was subject to variable interest rates. The remainder of our debt has fixed interest rates. Our fixed interest rate debt includes $150.0 million (face value) in senior notes. The carrying value and market value of our debt at June 30, 2007 was $150.4 million. Based upon debt balances outstanding at June 30, 2007, a 100 basis point (i.e., 1%) addition to our weighted average effective interest rate for variable rate debt would not have a material impact on our interest expense.

Foreign Currency Risk

     We had an investment in a subsidiary in Canada and sold our services into this foreign market.

     Our foreign net asset/exposure (defined as assets denominated in foreign currency less liabilities denominated in foreign currency) for Canada at June 30, 2007 of U.S. dollar equivalents was a net asset of $0.1 million as of June 30, 2007 compared to $1.7 million at December 31, 2006.

ITEM 4. CONTROLS AND PROCEDURES

     As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended). Based upon that evaluation, we concluded that as of June 30, 2007, our disclosure controls and procedures are effective to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosures.

Changes in Internal Control over Financial Reporting

     There were no changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

     Refer to Note 8 to our consolidated financial statements of this Quarterly Report on Form 10-Q for a discussion of any recent material developments related to our legal proceedings since the filing of our most recent Annual Report on Form 10-K.

ITEM 1A. RISK FACTORS

     Except as set forth below, there have been no material changes to any of the risk factors disclosed in our most recently filed Annual Report on Form 10-K.

We derive a significant portion of our revenue from a few customers, and the loss of one of these customers or a reduction in their demand, the amount they pay or their ability to pay, for our services could impair our financial performance.

     In the three months ended June 30, 2007, we derived approximately 42.7% and 10.7% of our revenue from DIRECTV^® and Verizon, respectively. During the six month period ended June 30, 2007, we derived approximately 44.1% and 10.4% of our revenue from DIRECTV^® and Verizon, respectively. Because our business is concentrated among relatively few major customers, our revenue could significantly decline if we lose one or more of these customers or if the amount of business from any of these customer reduces significantly, which could result in reduced profitability and liquidity.
