Senior Secured Notes

On January 12, 2010, PAETEC Holding issued and sold $300.0 million in aggregate principal amount of its 8 ⁷/8% senior secured notes due 2017 (the “Notes”) pursuant to the indenture, dated as of June 29, 2009 as supplemented from time to time (the “Indenture”), by and among PAETEC Holding, the subsidiary guarantors named therein and The Bank of New York Mellon, as trustee. Immediately following the issuance and sale of the Notes, PAETEC Holding had $650.0 million in aggregate principal amount of its 8 ⁷/8% senior secured notes due 2017 outstanding under the Indenture.

The Company sold the Notes at an offering price of 100.528% of the principal amount of the Notes, plus accrued interest from December 31, 2009, in an offering not subject to the registration requirements of the Securities Act of 1933 (the “Securities Act”). The Company applied the gross proceeds of $301.6 million it received from the sale of the Notes to repay $240.2 million in aggregate principal amount of term loans and $30.0 million in aggregate principal amount of revolving loans outstanding under its senior secured credit facilities and to pay $8.3 million of fees incurred in connection with the termination of the remaining $265.0 million notional amount of its swap agreement in effect as of January 12, 2010. The Company paid a total of approximately $9.0 million of offering fees and expenses. The Company will use the remaining $14.1 million of offering proceeds for general corporate purposes.

In connection with the Company’s application of the gross proceeds received from the sale of the Notes to repay the outstanding principal amount under its senior secured credit facilities, as described above in this Note 4, the Company recognized $4.4 million of debt extinguishment and related costs in the accompanying consolidated statements of operations and comprehensive loss. This amount represents the elimination of $3.6 million of debt issuance costs and unamortized debt discount related to the Company’s existing senior secured credit facilities that were paid in full with the proceeds from the Notes and $0.8 million of costs related to the termination of its interest rate swap agreement.

7

On July 26, 2010, in accordance with registration rights granted to the purchasers of the Notes, the Company completed an exchange offer of the Notes for notes with substantially identical terms registered under the Securities Act.

Senior Credit Facilities

Immediately following the sale of the Notes in January 2010 and the Company’s application of the offering proceeds to the foregoing uses, the Company’s senior secured credit facilities consisted of the following:

• a term loan credit facility under which no term loans were outstanding and under which the Company could obtain incremental term loans, subject to conditions, in an aggregate principal amount of up to approximately $65.0 million under one or more incremental facilities; and

• a revolving credit facility under which no revolving loans were outstanding and under which the Company could obtain from time to time revolving loans of up to an aggregate principal amount of $50.0 million outstanding at any time.

No amounts were outstanding under either credit facility as of June 30, 2010.

Financial Covenant

Under the terms of the total leverage ratio covenant contained in the Company’s credit agreement for its senior credit facilities, the Company’s ratio of consolidated debt to consolidated adjusted EBITDA (as defined for purposes of the credit agreement) as of any measurement date will not be permitted to be greater than 5.00: 1.00. The Company was in compliance with this financial covenant as of June 30, 2010.

Fair Value of Financial Instruments

The carrying value of the Company’s financial instruments, other than debt, does not materially differ from the estimated fair values as of June 30, 2010. As of June 30, 2010, the $300.0 million principal amount of the Company’s 9.5% senior notes due 2015 had an estimated fair market value of approximately $291.8 million, and the $650.0 million principal amount of the Company’s 8 ⁷/8% senior secured notes due 2017 had an estimated fair market value of approximately $650.0 million. The estimated market values as of June 30, 2010 are based on quarter-end closing market prices published by securities firms. While the Company believes these approximations to be reasonably accurate at the time published, quarter-end closing market prices can vary widely depending on volume traded by any given security firm and other factors.

5. INCOME TAXES

The Company completed a reorganization involving some of PAETEC Holding’s direct and indirect wholly-owned subsidiaries during the six months ended June 30, 2010. The benefit for income taxes for the six months ended June 30, 2010 reflects the impact to deferred taxes from the reorganization, net of certain current state taxes and income taxes in selected jurisdictions where net operating losses are not available.

ASC 740, Income Taxes, requires the recognition of a financial statement benefit of a tax position only after a determination that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The amount of unrecognized tax benefits from uncertain tax positions as of June 30, 2010 was $0.4 million, the majority of which, if recognized, would affect the effective tax rate.

The Company recognizes interest and penalties accrued on unrecognized tax benefits as a component of the provision for income taxes. As of June 30, 2010, the Company had less than $0.1 million of accrued interest related to unrecognized tax benefits.

The Company files U.S. federal income tax returns and income tax returns in various state jurisdictions. The Company is no longer subject to U.S. federal, state, and local tax examinations in major tax jurisdictions for periods before the year ended December 31, 2005.

6. STOCKHOLDERS’ EQUITY

During the three and six months ended June 30, 2010, PAETEC Holding repurchased, at fair market value and on the open market, a total of 1,146,675 shares of its common stock at a total cost of approximately $4.5 million. In connection with the repurchase, PAETEC Holding paid commissions totaling less than $0.1 million. The repurchased shares were retired and resumed the status of authorized and unissued shares.

7. SHARE-BASED TRANSACTIONS

Employee Stock Purchase Plan

As of June 30, 2010, purchase rights for 1,687,332 shares had been granted under PAETEC Holding’s Employee Stock Purchase Plan (“ESPP”) and 2,412,668 shares of common stock remained available for issuance.

During the three month purchase periods ended March 31, 2010 and June 30, 2010, PAETEC Holding issued 143,297 and 160,837 shares, respectively, at respective purchase prices of approximately $4.21 and of $3.07 per share, which represented 90% of the closing price of the common stock as reported on the NASDAQ Global Select Market on March 31, 2010 and June 30, 2010, respectively. Compensation expense attributable to the ESPP for the three and six months ended June 30, 2010 totaled approximately $0.1 million.

Stock Option Activity

The following table summarizes stock option activity for the six months ended June 30, 2010:

8. LOSS PER COMMON SHARE

The computation of basic and diluted loss per common share for the three and six months ended June 30, 2010 and 2009, was as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
(in thousands, except share and per share data)	2010			2009			2010			2009
Net loss	$	(7,528	)	$	(16,485	)	$	(17,066	)	$	(19,793	)
Weighted average common shares outstanding – basic and diluted		146,079,877			141,614,010			145,782,588			141,234,411
Net Loss per common share – basic and diluted	$	(0.05	)	$	(0.12	)	$	(0.12	)	$	(0.14	)

For the three and six months ended June 30, 2010 and 2009, the Company had outstanding options, warrants and restricted stock units for 18,543,629 and 19,824,842 shares, respectively, which were exercisable for or represented common shares that were not included in the calculation of diluted loss per common share because the effect would have been anti-dilutive.

9. COMMITMENTS AND CONTINGENCIES

Purchase Commitments

As of June 30, 2010, the Company had entered into agreements with vendors to purchase approximately $29.6 million of equipment and services, of which the Company expects $25.2 million to be delivered and payable in the year ending December 31, 2010, $2.6 million in the year ending December 31, 2011, $1.6 million in the year ending December 31, 2012, and $0.2 million in the year ending December 31, 2013.

Data and Voice Services

The Company has various agreements with certain carriers for data and voice services. As of June 30, 2010, the Company’s minimum commitments under these agreements totaled $203.0 million, of which $59.4 million expire in the year ending December 31, 2010, $118.7 million expire in the year ending December 31, 2011, $11.5 million expire in the year ending December 31, 2012, $11.5 million expire in the year ending December 31, 2013, and the remaining $1.9 million expire in the year ending December 31, 2014. Related expenses, when incurred, are included in cost of sales in the accompanying condensed consolidated statements of operations and comprehensive loss.

Regulation

The Company’s services are subject to varying degrees of federal, state and local regulation. These regulations are subject to ongoing proceedings at federal and state administrative agencies or within state and federal judicial systems. Results of these proceedings could change, in varying degrees, the manner in which the Company operates. The Company cannot predict the outcome of these proceedings or their effect on the Company’s industry generally or on the Company specifically.

Interconnection and Network Access Agreements

The Company is dependent on the use of incumbent local exchange carriers’ local and transport networks and access services to provide telecommunications services to its customers. Charges for leasing local and transport network components and purchasing special access services historically have made up a significant percentage of the Company’s overall cost of providing the services. These network components and services are purchased in each PAETEC market through interconnection agreements, special access contracts, commercial agreements or a combination of such agreements from the incumbent local exchange carrier, or, where available, from other wholesale network service providers. These costs are recognized in the period in which the services are delivered and are included as a component of the Company’s cost of sales in the accompanying condensed consolidated statements of operations and comprehensive loss.

Letters of Credit

The Company is party to letters of credit totaling $6.9 million as of June 30, 2010. The Company does not expect any material losses from these financial instruments since performance under these letters of credit is not likely to be required.

12

Litigation

The Company is party to various legal proceedings, most of which relate to routine matters incidental to the Company’s business. The result of any current or future litigation is inherently unpredictable. The Company’s management, however, believes that there is no litigation asserted or pending against the Company that could have, individually or in the aggregate, a material adverse effect on its financial position, results of operations or cash flows, except as indicated below.

In October 2008, PaeTec Communications, Inc. filed a claim in the Supreme Court for the State of New York, County of Monroe, against Lucent Technologies, Inc., Alcatel USA Marketing, Inc. and Alcatel-Lucent (collectively “Alcatel-Lucent”) for reimbursement of costs and fees in connection with a patent infringement case brought against the Company by Sprint Communications Company L.P. (“Sprint”) and settled in May 2009. The Company’s claim against Alcatel-Lucent alleges that because the Sprint claims arose from the use by the Company of Alcatel-Lucent equipment, Alcatel-Lucent has an obligation to defend and indemnify the Company pursuant to the contract terms under which it sold the equipment to the Company. Alcatel-Lucent has denied the claim and counter-claimed against the Company for allegedly unpaid switch software licensing charges, and associated late fees. The Company believes that it has meritorious defenses against these counter-claims. At this time, the Company is unable to estimate a potential loss or range of loss, if any.

10. FAIR VALUE MEASUREMENTS

The provisions of ASC 820, Fair Value Measurements and Disclosures, establishes a framework for measuring the fair value of financial assets and financial liabilities by establishing a hierarchy that categorizes and prioritizes the sources to be used to estimate fair value as follows:

Level 1 —defined as observable inputs such as quoted prices in active markets;

Level 2 —inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs); and

Level 3 —unobservable inputs that reflect the Company’s determination of assumptions that market participants would use in pricing the asset or liability. These inputs are developed based on the best information available, including the Company’s own data.

The following table summarizes the valuation of the Company’s financial instruments by the foregoing fair value hierarchy levels as of June 30, 2010 and December 31, 2009, respectively (in thousands):

	Fair Value Measurements as of June 30, 2010 Using:
	(Level 1)		(Level 2)		(Level 3)
Assets
Cash and cash equivalents	$	32,799		—	—
Short term investments	$	1,972
Other assets, net	$	2,669		—	—
	Fair Value Measurements as of December 31, 2009 Using:
	(Level 1)		(Level 2)		(Level 3)
Assets
Cash and cash equivalents		—	$	131,408	—
Liabilities
Interest rate swaps		—	$	7,544	—

At June 30, 2010, the fair value of cash and cash equivalents presented in the table above were primarily composed of the Company’s investments in publicly traded money market instruments. The Company’s cash and cash equivalent balances excluded from the table above are composed of cash, certificates of deposits with original maturities of one month or less and overnight investments. The fair value of the Company’s short term investments are comprised of publicly traded commercial paper instruments and the other assets, net consists of restricted investments in publicly traded money market instruments.

11. RECENT ACCOUNTING PRONOUNCEMENTS

In October 2009, the Financial Accounting Standards Board (“FASB”) FASB issued Accounting Standards Update (“ASU”) 2009-13, Revenue Recognition (Topic 605). This ASU provides amendments to the criteria in ASC 605-25 for separating consideration in multiple-deliverable revenue arrangements. It establishes a hierarchy of selling prices to determine the selling price of each specific deliverable, which includes vendor-specific objective evidence (if available), third-party evidence (if vendor-specific evidence is not available), or estimated selling price if neither of the first two is available. This ASU also eliminates the residual method for allocating revenue between the elements of an arrangement and requires that arrangement consideration be allocated at the inception of the arrangement. Finally, this ASU expands the disclosure requirements regarding a vendor’s multiple-deliverable revenue arrangements. This ASU is effective for fiscal years beginning on or after June 15, 2010. The Company is currently evaluating the impact of this ASU on its financial statements.

In October 2009, the FASB issued ASU 2009-14, Certain Revenue Arrangements that include Software Elements. This ASU amends accounting and reporting guidance under ASC 605-985 to exclude from its scope all tangible products containing both software and non-software components that function together to deliver the product’s essential functionality. ASU 2009-14 will be effective for fiscal years beginning on or after June 15, 2010. The Company is currently evaluating the impact of this ASU on its financial statements.

12. SUBSEQUENT EVENTS

In accordance with the provisions of ASC 855, Subsequent Events, the Company has evaluated all subsequent events to ensure that this Form 10-Q includes appropriate disclosure of events both recognized in the financial statements as of June 30, 2010, and events which occurred subsequent to June 30, 2010 but were not recognized in the financial statements. No subsequent events which required recognition or disclosure were identified, except as discussed below.

Registered Exchange Offer for Notes

On July 26, 2010, in accordance with registration rights granted to the purchasers of the Notes, the Company completed an exchange offer of the Notes for notes with substantially identical terms registered under the Securities Act.

Overview

PAETEC is a competitive communications services and solutions provider guided by the principle that delivering superior customer service is the key to competing successfully with other communications services providers. PAETEC’s primary business is providing large, medium-sized and, to a lesser extent, small business end-user customers in metropolitan areas with a package of integrated communications services that encompasses data services, including broadband Internet access services and virtual private network services, and voice services, including local telephone services and domestic and international long distance services. As of June 30, 2010, PAETEC Holding had in service 240,844 digital T1 transmission lines, which represented the equivalent of 5,780,256 access lines, for approximately 42,000 business customers in a service area encompassing 84 of the top 100 metropolitan statistical areas. As of the same date, PAETEC also had in service an incremental 250,413 access lines, of which 84,153 access lines related to the company’s non-core “plain old telephone service,” or “POTS,” operations.

Revenue. PAETEC derives revenue from sales of its network services, carrier services and integrated solutions services. PAETEC derives most of its revenue from monthly recurring fees and usage-based fees that are generated principally by sales of its network services.

Monthly recurring fees include the fees paid by PAETEC’s customers for lines in service and additional features on those lines. PAETEC primarily bills monthly recurring fees in advance.

Usage-based fees consist of fees paid by PAETEC’s network services customers for each call made, fees paid by the incumbent carriers in PAETEC’s markets as “reciprocal compensation” when PAETEC terminates local calls made by their customers, and access fees paid by other carriers for long distance calls PAETEC originates or terminates for those carriers.

The monthly recurring fees and usage-based fees generated by sales of PAETEC’s network services to end users and carrier services to any customer tend to be relatively consistent from month to month, subject to changes in the calling patterns of the customer’s business. These fees generally are based on the number of digital T1 transmission lines used by the customer. Because PAETEC believes that the cumulative number of digital T1 transmission lines in service provides accurate information with respect to its revenue prospects, the company uses data with respect to the cumulative number of digital T1 transmission lines PAETEC has in service from period to period to assist it in evaluating revenue trends related to its network services and carrier services businesses.

Network Services. PAETEC delivers integrated communications services, including data and Internet services, local services and long distance services, to end users on a retail basis, which the company refers to as its “network services.” PAETEC’s network services revenue consists primarily of monthly recurring fees and usage-based fees. In addition to usage-based fees invoiced directly to the end-user customers, usage-based fees for PAETEC’s network services include the interstate and intrastate access fees the company receives from other communications providers when it originates or terminates long-distance calls for those other providers to or from PAETEC’s network services customers, and the reciprocal compensation fees PAETEC receives from some other local carriers when it terminates non-toll calls originated by customers of other carriers. PAETEC recognizes revenue during the period in which the revenue is earned. PAETEC’s network services also generate non-recurring service activation and installation fee revenues, which it receives upon initiation of service. PAETEC defers recognition of these revenues and amortizes them over the average customer life.

PAETEC’s core network services are those that generate revenue from retail enterprise customers to which PAETEC delivers such integrated communications services on primarily Tl or larger access lines, which excludes access fee and reciprocal compensation fee revenue related to network services and revenue from the company’s POTS operations. POTS operations involve the provision of basic telephone services supplying standard single line telephones, telephone lines and access to the public switched network.

15

Carrier Services. PAETEC generates revenue from wholesale sales of communications services to other communications businesses, which the company refers to as its “carrier services.” PAETEC’s carrier services revenue consists primarily of monthly recurring fees and usage-based fees. Usage-based fees for PAETEC’s carrier services include interstate and intrastate access fees the company receives from other communications providers when it originates or terminates long distance calls for those other providers to or from PAETEC’s carrier services customers, and the reciprocal compensation fees PAETEC receives from some other local carriers when it terminates to its carrier services customers local calls made by customers of other local carriers.

PAETEC’s core carrier services are those that generate revenue from other communications providers, which excludes access fee and reciprocal compensation fee revenue related to carrier services and revenue from the company’s non-core POTS operations.

Integrated Solutions. PAETEC derives revenue from sales to retail end-user customers of telecommunications equipment and software and related services and energy supply services, which collectively the company refers to as its “integrated solutions.”

A portion of PAETEC’s integrated solutions revenue consists of fees its customers pay for equipment and for PAETEC’s system design and installation services. PAETEC recognizes revenue for equipment sales and system design and installation services upon delivery and acceptance of the underlying equipment.

PAETEC derives an additional component of its integrated solutions revenue by selling and supporting its proprietary telecommunications software. PAETEC recognizes revenue related to software sales upon delivery of the software. Support fees include fees for maintenance of PAETEC’s telecommunications software and fees for training the end user in the proper use of that software. PAETEC recognizes maintenance fees on a pro rata basis over the length of the underlying maintenance contract and training fees after it fulfills the training obligation.

The energy revenue consists primarily of usage-based fees its customers pay for unregulated electricity. Revenues are subject to variability based upon market based factors.

Cost of Sales. PAETEC provides its network services and carrier services by using electronic network components that it owns and telephone and data transmission lines that it leases from other telecommunications carriers. PAETEC’s cost of sales for these services consists primarily of leased transport charges and usage costs for local and long distance calls. PAETEC’s leased transport charges are the payments it makes to lease the telephone and data transmission lines, which the company uses to connect its customers to its network and to connect its network to the networks of other carriers. Usage costs for local and long distance are the costs that PAETEC incurs for calls made by its customers. Cost of sales for PAETEC’s integrated solutions includes the costs it incurs in designing systems and purchasing and installing equipment and the costs incurred in procuring electricity from the market operators on a wholesale basis.

Selling, General and Administrative Expenses. PAETEC’s selling, general and administrative expenses include selling and marketing, customer service, billing, corporate administration, engineering personnel and other personnel costs.

Depreciation and Amortization. Depreciation and amortization include depreciation of PAETEC’s telecommunications network and equipment, computer hardware and purchased software, office equipment, furniture and fixtures, and buildings, as well as amortization of intangible assets.

Debt Extinguishment and Related Costs. PAETEC’s debt extinguishment and related costs include expenses related to the repayment of outstanding term loans under PAETEC’s senior secured credit facilities and costs incurred related to PAETEC’s former interest rate swap agreement.

Interest Expense. Interest expense includes interest due on PAETEC’s long-term debt and capital leases, amortization of debt issuance costs, debt premiums, and debt discounts.

Other Income, Net. Other income, net includes non-monetary gains on the exchange of reciprocal indefeasible rights of use, or “IRUs,” investment income, and other financing income.

Accounting for Income Taxes. PAETEC recognizes deferred income tax assets and liabilities for the expected future tax consequences of transactions and events. Under this method, PAETEC determines deferred income tax assets and liabilities based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which it expects the differences to reverse. If necessary, PAETEC reduces deferred income tax assets by a valuation allowance to an amount that it determines is more likely than not to be recoverable. PAETEC makes significant estimates and assumptions about future taxable income and future tax consequences to determine the amount of the valuation allowance.

16

Stock-Based Compensation

PAETEC’s employees participate in a variety of equity incentive plans. Stock-based compensation expense for all stock-based compensation awards is based on the grant date fair value estimated in accordance with the Financial Accounting Standards Board, or “FASB,” Accounting Standards Codification, or “ASC,” Topic 718, Compensation—Stock Compensation. PAETEC recognizes these compensation costs, net of an estimated forfeiture rate, ratably over the requisite service period of the award.

Results of Operations

The following table presents selected operating data for the three and six months ended June 30, 2010 and 2009. In the following comparisons of PAETEC’s operating results, we refer to the three months ended June 30, 2010 as our “2010 quarter” and we refer to the three months ended June 30, 2009 as our “2009 quarter.” We refer to the six months ended June 30, 2010 as our “2010 six-month period” and the six months ended June 30, 2009 as our “2009 six-month period.” PAETEC’s operating results for the three and six months ended June 30, 2010 and 2009 were as follows (dollars in thousands):

Three Months Ended June 30, 2010 Compared With Three Months Ended June 30, 2009

Revenue. Total revenue increased $0.9 million, or 0.2%, to $396.1 million for the 2010 quarter from $395.2 million for the 2009 quarter, principally because of the inclusion of revenue from recent acquisitions that more than offset declines in usage-based revenue and non-core POTS revenue. Of total revenue for the 2010 quarter, revenue from network services, carrier services and integrated solutions accounted for 78.3%, 15.9% and 5.8%, respectively, compared to 79.2%, 16.9% and 3.9%, respectively, for the 2009 quarter.

Revenue from network services decreased $2.7 million, or 0.9%, to $310.2 million for the 2010 quarter from $312.9 million for the 2009 quarter. Of total network services revenue for the 2010 quarter, revenue from core network services, access fee and reciprocal compensation revenue related to network services, and non-core POTS revenue related to network services accounted for 91.8%, 5.3% and 2.9%, respectively, compared to 90.9%, 5.4% and 3.7%, respectively, for the 2009 quarter.

Revenue from core network services increased $0.3 million, or 0.1%, to $284.9 million for the 2010 quarter from $284.6 million for the 2009 quarter. For the 2010 quarter, revenue from monthly recurring fees and usage-based fees accounted for 76.8% and 22.4%, respectively, of revenue from core network services, compared to 76.4% and 22.9%, respectively, of such revenue for the 2009 quarter. The increase in core network services revenue primarily resulted from an increase in the number of digital T1 transmission lines in service for the 2010 quarter and increased data revenue generated by increased sales of Dynamic IP and MPLS VPN products, which were substantially offset by a decline in usage-based revenue.

Access fee revenue and reciprocal compensation included in network services revenue decreased $0.2 million, or 1.4%, to $16.6 million for the 2010 quarter from $16.8 million for the 2009 quarter. Of total access fee revenue and reciprocal compensation included in network services for the 2010 quarter, revenue from access fees accounted for 92.2% compared to 89.7% for the 2009 quarter.

Non-core POTS revenue included in network services revenue decreased $2.8 million, or 23.8%, to $8.8 million for the 2010 quarter from $11.6 million for the 2009 quarter. The decrease in non-core POTS revenue primarily resulted from continued customer attrition as the weighted average number of POTS access lines in-service declined to 29,080 for the 2010 quarter from 40,687 for the 2009 quarter.

Revenue from carrier services decreased $3.7 million, or 5.5%, to $63.1 million for the 2010 quarter from $66.8 million for the 2009 quarter. Of total carrier services revenue for the 2010 quarter, revenue from core carrier services, access fee and reciprocal

18

compensation revenue related to carrier services, and non-core POTS revenue related to carrier services accounted for 71.4%, 23.3% and 5.3%, respectively, compared to 72.2%, 20.7% and 7.1%, respectively, for the 2009 quarter.

Revenue from core carrier services decreased $3.2 million, or 6.6%, to $45.0 million for the 2010 quarter from $48.2 million for the 2009 quarter. The decrease in core carrier services revenue primarily resulted from a decline in usage-based revenue. For the 2010 quarter, revenue from monthly recurring fees and usage-based fees accounted for 58.6% and 27.4%, respectively, of revenue from core carrier services, compared to 55.6% and 30.6%, respectively, of such revenue for the 2009 quarter.

Access fee revenue and reciprocal compensation included in carrier services revenue increased $0.8 million, or 6.1%, to $14.7 million for the 2010 quarter from $13.9 million for the 2009 quarter. Of total access fee revenue and reciprocal compensation included in carrier services for the 2010 quarter, revenue from access fees accounted for 85.4% compared to 75.6% for the 2009 quarter.

Non-core POTS revenue included in carrier services revenue decreased $1.3 million, or 28.7%, to $3.4 million for the 2010 quarter from $4.7 million for the 2009 quarter. The decrease in non-core POTS revenue primarily resulted from continued customer attrition, as the weighted average number of local wholesale POTS lines in-service declined to 57,669 for the 2010 quarter from 78,191 for the 2009 quarter.

Revenue from integrated solutions services increased $7.3 million, or 47.5%, to $22.8 million for the 2010 quarter from $15.4 million for the 2009 quarter. Of this increase, $6.9 million was attributable to growth in both equipment sales and energy services as a result of PAETEC’s February 28, 2010 acquisition of U.S. Energy Partners and its June 7, 2010 acquisition of Quagga Corporation.

Cost of Sales. Cost of sales decreased to $196.8 million for the 2010 quarter from $196.9 million for the 2009 quarter, in part because of a decline in minutes of use as PAETEC’s product mix continues to evolve away from more usage-sensitive products, which was substantially offset by the costs incurred to procure electricity from market operators on a wholesale basis.

Leased transport charges decreased to $152.1 million, or 77.3% of cost of sales, for the 2010 quarter from $153.1 million, or 77.8% of cost of sales, for the 2009 quarter.

Usage costs for local and long distance calls decreased to $29.4 million, or 15.0% of cost of sales, for the 2010 quarter from $33.3 million, or 16.9% of cost of sales, for the 2009 quarter. The decrease was attributable to a decline in the average usage rates PAETEC is charged by network providers, as well as to a decline in minutes of use.

Cost of sales as a percentage of total revenue was 49.7% for the 2010 quarter and 49.8% for the 2009 quarter.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased to $136.8 million for the 2010 quarter from $140.6 million for the 2009 quarter. Salaries, wages and benefits decreased by $2.2 million, primarily due to a decrease in bonus expense. Selling, general and administrative expenses as a percentage of total revenue decreased to 34.5% for the 2010 quarter from 35.6% for the 2009 quarter.

Depreciation and Amortization. Depreciation and amortization expense increased to $47.4 million for the 2010 quarter from $46.2 million for the 2009 quarter. The increase was primarily attributable to PAETEC’s network deployment and maintenance activities.

Debt Extinguishment and Related Costs. In connection with the June 2009 issuance of its 8 ⁷/8% senior secured notes due 2017, PAETEC recognized $10.3 million of debt extinguishment and related costs during the 2009 quarter, which reflected the elimination of $5.8 million of debt issuance costs and unamortized debt discount related to the repayment of approximately $330.5 million of outstanding term loans under the company’s existing senior secured credit facilities and $4.5 million of costs incurred related to the reduction of the notional amount of its swap agreement in effect as of June 30, 2009 from $400.0 million to $265.0 million.

Interest Expense. PAETEC’s average outstanding debt balances increased to $975.2 million for the 2010 quarter from $930.7 million for the 2009 quarter, as a result of the January 2010 issuance of $300 million aggregate principal amount of its 8 ⁷/8% senior secured notes due 2017 and the repayment of the outstanding principal amount under its senior secured credit facilities. Interest expense increased to $22.6 million for the 2010 quarter from $17.3 million for the 2009 quarter due primarily to an increase in the average annual borrowing rate. The weighted average annual borrowing rate for the 2010 quarter was 9.1%, compared to 7.3% for the 2009 quarter.

Income Taxes. PAETEC completed a reorganization involving some of PAETEC Holding Corp.’s direct and indirect wholly-owned subsidiaries during the period ended March 31, 2010. The provision for income taxes for the 2010 quarter reflects the impact to deferred taxes from the reorganization, net of certain current state taxes and income taxes in selected jurisdictions where net operating

19

losses are not available. The difference between the statutory rate and the effective tax rate for the 2010 quarter was primarily attributable to the existence of a valuation allowance on PAETEC’s net deferred tax assets.

Six Months Ended June 30, 2010 Compared With Six Months Ended June 30, 2009

Revenue. Total revenue decreased $8.3 million, or 1.0%, to $786.2 million for the 2010 six-month period from $794.4 million for the 2009 six-month period, primarily due to declines in usage-based revenue and non-core POTS revenue, which were partially offset by the inclusion of revenue from recent acquisitions. Of total revenue for the 2010 six-month period, revenue from network services, carrier services and integrated solutions accounted for 79.0%, 16.0% and 5.0%, respectively, compared to 79.3%, 17.1% and 3.6%, respectively, for the 2009 six-month period.

The decrease in non-core POTS revenue primarily resulted from continued customer attrition, as the weighted average number of POTS access lines in-service declined to 30,248 for the 2010 six-month period from 42,608 for the 2009 six-month period.

Revenue from carrier services decreased $9.4 million, or 6.9%, to $126.1 million for the 2010 six-month period from $135.5 million for the 2009 six-month period. Of total carrier services revenue for the 2010 six-month period, revenue from core carrier services, access fee and reciprocal compensation fee revenue related to carrier services, and non-core POTS revenue related to carrier services accounted for 71.1%, 23.4% and 5.5%, respectively, compared to 71.9%, 21.1% and 7.0%, respectively, for the 2009 six-month period.

Revenue from core carrier services decreased $7.7 million, or 7.9%, to $89.7 million for the 2010 six-month period from $97.4 million for the 2009 six-month period. The decrease in core carrier services revenue primarily resulted from a decline in usage-based revenue. For the 2010 six-month period, revenue from monthly recurring fees and usage-based fees accounted for 59.3% and 27.2%, respectively, of revenue from core carrier services, compared to 53.4% and 34.0%, respectively, of such revenue for the 2009 six-month period.

The decrease in non-core POTS revenue primarily resulted from continued customer attrition, as the weighted average number of local wholesale POTS lines in-service declined to 59,777 for the 2010 six-month period from 79,539 for the 2009 six-month period.

Revenue from integrated solutions services increased $10.4 million, or 36.2%, to $39.3 million for the 2010 six-month period from $28.9 million for the 2009 six-month period. Of this increase, $8.5 million was attributable to growth in both equipment sales and energy services as a result of recent business acquisitions.

Cost of Sales. Cost of sales decreased to $389.5 million for the 2010 six-month period from $395.8 million for the 2009 six-month period, in part because of a decline in minutes of use as PAETEC’s product mix continues to evolve away from more usage-sensitive products, which was substantially offset by the costs incurred to procure electricity from market operators on a wholesale basis.

Leased transport charges increased to $305.1 million, or 78.3% of cost of sales, for the 2010 six-month period from $304.9 million, or 77.0% of cost of sales, for the 2009 six-month period.

20

The decrease was attributable to a decline in the average usage rates PAETEC is charged by network providers, as well as to a decline in minutes of use.

Cost of sales as a percentage of total revenue decreased slightly from 49.8% for the 2009 six-month period to 49.5% for the 2010 six-month period.

Selling, General and Administrative Expenses. Selling, general and administrative expenses decreased to $271.1 million for the 2010 six-month period from $281.6 million for the 2009 six-month period.

Selling, general and administrative expenses as a percentage of total revenue decreased to 34.5% for the 2010 six-month period from 35.4% for the 2009 six-month period.

Depreciation and Amortization. Depreciation and amortization expense increased to $94.6 million for the 2010 six-month period from $92.4 million for the 2009 six-month period. The increase was primarily attributable to PAETEC’s network deployment and maintenance activities.

Debt Extinguishment and Related Costs. During the 2010 six-month period, PAETEC recognized a total of $4.4 million of debt extinguishment and related costs, which represented the elimination of $3.6 million of debt issuance costs and unamortized debt discount associated with the repayment of $240.2 million in aggregate principal amount of term loans and $30.0 million in aggregate principal amount of revolving loans outstanding under its senior secured credit facilities with the proceeds from the January 2010 issuance of its 8 ⁷/8% senior secured notes due 2017 and $0.8 million of costs related to the termination of its interest rate swap agreement.

Interest Expense. PAETEC’s average outstanding debt balances increased to $975.8 million for the 2010 six-month period from $933.8 million for the 2009 six-month period, as a result of the January 2010 issuance of $300 million aggregate principal amount of its 8 ⁷/8% senior secured notes due 2017 and the repayment of the outstanding principal amount under its senior secured credit facilities. Interest expense increased to $44.6 million for the 2010 six-month period from $34.5 million for the 2009 six-month period due primarily to an increase in the average annual borrowing rate. The weighted average annual borrowing rate for the 2010 six-month period was 8.9%, compared to 7.2% for the 2009 six-month period.

Income Taxes. PAETEC completed a reorganization involving some of PAETEC Holding Corp.’s direct and indirect wholly-owned subsidiaries during the 2010 six-month period. The benefit from income taxes for the 2010 six-month period reflects the impact to deferred taxes from the reorganization, net of certain current state taxes and income taxes in selected jurisdictions where net operating losses are not available. The difference between the statutory rate and the effective tax rate for the 2010 six-month period was primarily attributable to the existence of a valuation allowance on PAETEC’s net deferred tax assets.

Liquidity and Capital Resources

PAETEC finances its operations and growth primarily with cash flow from operations, issuances of debt securities and other loans, operating leases and normal trade credit terms.

Sources and Uses of Cash. PAETEC’s cash flows for the six months ended June 30, 2010 and 2009, respectively, were as follows (in thousands):

	Six Months Ended June 30,
	2010			2009
Net cash provided by operating activities	$	44,749		$	49,330
Net cash used in investing activities	$	(88,031	)	$	(56,684	)
Net cash provided by (used in) financing activities	$	14,063		$	(17,471	)

The $4.6 million decrease in cash flows from operating activities for the 2010 six-month period compared to the 2009 six-month period was primarily attributable to a $4.9 million decrease in net income adjusted for non-cash items.

PAETEC’s investing activities during the 2010 six-month period and the 2009 six-month period consisted primarily of activities related to the purchase of property and equipment. Investing activities during the 2010 six-month period also included investment in the acquisitions of U.S. Energy Partners LLC and Quagga Corporation.

Net cash provided by financing activities of $14.1 million for the 2010 six-month period was primarily related to the issuance and sale of $300.0 million in aggregate principal amount of its 8 ⁷/8% senior secured notes due 2017, partially offset by the payment of

21

debt issuance costs incurred in connection with such sale. PAETEC applied a portion of the proceeds from the January 2010 sale of the 8 ⁷/8% senior secured notes to repay $240.2 million in aggregate principal amount of term loans and $30.0 million in aggregate principal of revolving loans outstanding under its senior secured credit facilities. Net cash used in financing activities of $17.5 million for the 2009 six-month period was primarily related to the repayment of $330.5 million principal amount of borrowings under PAETEC’s senior secured credit facilities with the proceeds of its sale of $350 million principal amount of its 8 ⁷/8% senior secured notes due 2017, the payment of debt issuance costs incurred in connection with such sale, and payments of tax withholding amounts on stock units that vested during the period in lieu of issuing shares of common stock of equal value.

Contractual Obligations. PAETEC has various contractual obligations and commercial commitments. PAETEC does not have off-balance sheet financing arrangements other than its letters of credit and operating leases.

There were no material changes in PAETEC’s contractual obligations as set forth in PAETEC’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2010.

Indebtedness. At June 30, 2010, PAETEC had approximately $975.0 million of total indebtedness, net of an unamortized discount of $9.1 million. The overall weighted average annual interest rate, including the debt discount and debt premium but excluding deferred financing costs, was 8.9%. Of this total indebtedness, an aggregate principal amount of $300.0 million was outstanding under the company’s 9.5% senior notes due 2015 and an aggregate principal amount of $650.0 million was outstanding under the company’s 8 ⁷/8% senior secured notes due 2017.

On January 12, 2010, PAETEC Holding issued and sold $300.0 million in aggregate principal amount of its 8 ⁷/8% senior secured notes. Accordingly, immediately following the issuance and sale in January 2010 of the 8 ⁷/8% senior secured notes, the company had $650.0 million in aggregate principal amount of the 8 ⁷/8% senior secured notes outstanding. PAETEC Holding applied a portion of the proceeds from the January 2010 sale of the 8 ⁷/8% senior secured notes to repay $240.2 million in aggregate principal amount of term loans and $30.0 million in aggregate principal of revolving loans outstanding under its senior secured credit facilities.

Immediately following the sale in January 2010 of the senior secured notes and PAETEC’s application of the offering proceeds to the foregoing uses, PAETEC’s senior secured credit facilities consisted of the following:

• a term loan credit facility under which no term loans were outstanding and under which PAETEC could obtain incremental term loans, subject to conditions, in an aggregate principal amount of up to approximately $65.0 million under one or more incremental facilities; and

• a revolving credit facility under which no revolving loans were outstanding and under which PAETEC could obtain from time to time revolving loans of up to an aggregate principal amount of $50.0 million outstanding at any time.

No amounts were outstanding under either credit facility as of June 30, 2010.

Under the terms of the total leverage ratio covenant contained in PAETEC’s credit agreement for its senior credit facilities, PAETEC’s ratio of consolidated debt to consolidated adjusted EBITDA (as defined for purposes of the credit agreement) as of any measurement date will not be permitted to be greater than 5.00:1.00. PAETEC was in compliance with this financial covenant as of June 30, 2010.

See Note 4 to PAETEC’s condensed consolidated financial statements appearing elsewhere in this report for additional information regarding the company’s indebtedness.

Stock Repurchase Program. In 2009, PAETEC Holding’s board of directors authorized the repurchase of up to $25.0 million of PAETEC Holding’s outstanding common stock through December 31, 2010, subject to conditions. PAETEC Holding may repurchase shares from time to time, at its discretion, on the open market or in private transactions. The repurchase program does not obligate PAETEC Holding to repurchase any specific number of shares, and may be modified or discontinued at any time.

For the three and six months ended June 30, 2010, PAETEC Holding repurchased, at fair market value and on the open market, a total of 1,146,675 shares of its common stock at a total cost of approximately $4.5 million. In connection with the repurchase, PAETEC Holding paid commissions totaling less than $0.1 million. As of June 30, 2010, after taking into account repurchases made under the plan through such date and restrictions under its debt agreements, PAETEC Holding retained the ability to repurchase $11.7 million of common stock through December 31, 2010.

Capital and Cash Requirements. PAETEC expects that it will continue to require significant capital expenditures to maintain and enhance its network and services and to generate planned revenue growth. PAETEC made capital expenditures, principally for the

22

purchase of communications equipment, of approximately $60.9 million in the 2010 six-month period. PAETEC expects to fund all of its 2010 capital expenditures from cash on hand and cash flow from operations. PAETEC plans to make such capital expenditures primarily for the following purposes:

• to continue to acquire and install equipment to enhance and maintain its network;

• to increase penetration of its existing markets;

• to expand its operations into additional geographic markets; and

• to make infrastructure enhancements, principally for its back office systems.

The actual amount and timing of PAETEC’s capital requirements may differ materially from its estimates as a result of regulatory, technological and competitive developments in the company’s industry. As of June 30, 2010, PAETEC had entered into agreements with vendors to purchase approximately $29.6 million of equipment and services, of which PAETEC expects $25.2 million to be delivered and payable in the year ending December 31, 2010, $2.6 million in the year ending December 31, 2011, $1.6 million in the year ending December 31, 2012, and $0.2 million in the year ending December 31, 2013.

PAETEC may seek to purchase some of its outstanding 9.5% senior notes due 2015 and/or some of its outstanding 8 ⁷/8% senior secured notes for cash in open market transactions, privately negotiated transactions or otherwise. Such repurchases, if any, will depend on prevailing market conditions and the discount, if any, at which the notes may be purchased, PAETEC’s liquidity requirements, contractual restrictions and other factors. The amounts involved in any such purchases may be material.

PAETEC believes that cash on hand and cash flow from operations will provide sufficient cash to enable the company to fund its planned capital expenditures, make scheduled principal and interest payments on its debt, meet its other cash requirements, and maintain compliance with the terms of its financing agreements for at least the next 12 months. After the foregoing period, PAETEC may require additional capital for network enhancements to provide increased capacity to meet expected increased demand for its services. The amount and timing of these additional network enhancements, if any, will depend on the anticipated demand for services, the availability of funds and other factors. The actual amount and timing of PAETEC’s future capital requirements may differ materially from the company’s estimates depending on the demand for its services and new market developments and opportunities, and on other factors, including those described in Part I, “Item 1A. Risk Factors” in its Annual Report on Form 10-K for its 2009 fiscal year. If PAETEC’s plans or assumptions change or prove to be inaccurate, the foregoing sources of funds may prove to be insufficient. In addition, if PAETEC seeks to acquire other businesses or to accelerate the expansion of its business, it may be required to seek additional capital. Additional sources may include equity and debt financing and other financing arrangements, such as vendor financing. In addition, if PAETEC believes it can obtain additional debt financing on advantageous terms, PAETEC may seek such financing at any time, to the extent that market conditions and other factors permit it to do so. The debt financing PAETEC may seek could be in the form of term loans under its senior secured credit facilities or additional debt securities having substantially the same terms as, or different terms from, PAETEC’s outstanding senior notes and senior secured notes. Any inability of PAETEC to generate the sufficient funds that it may require or to obtain such funds under reasonable terms could limit its ability to increase its revenue or to operate profitably. PAETEC’s ability to raise any required funds is subject to restrictions imposed by covenants contained in its existing debt agreements and could be negatively affected by a continuation of adverse conditions in the credit and capital markets.

Critical Accounting Policies

PAETEC’s condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and the rules and regulations of the SEC. Preparing consolidated financial statements requires PAETEC to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. These estimates and assumptions are affected by the application of PAETEC’s accounting policies. PAETEC’s significant accounting policies are described in the note captioned “Summary of Significant Accounting Policies” in Note 2 to the consolidated financial statements included in PAETEC’s Form 10-K for its 2009 fiscal year, and a discussion of PAETEC’s critical accounting estimates is provided in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in that report.

Recent Accounting Pronouncements

In October 2009, the FASB issued Accounting Standards Update, or “ASU,” 2009-13, Revenue Recognition (Topic 605). This ASU provides amendments to the criteria in ASC 605-25 for separating consideration in multiple-deliverable revenue arrangements. It establishes a hierarchy of selling prices to determine the selling price of each specific deliverable, which includes vendor-specific objective evidence (if available), third-party evidence (if vendor-specific evidence is not available), or estimated selling price if neither of the first two is available. This ASU also eliminates the residual method for allocating revenue between the elements of an arrangement and requires that arrangement consideration be allocated at the inception of the arrangement. Finally, this ASU expands the disclosure requirements regarding a vendor’s multiple-deliverable revenue arrangements. This ASU is effective for fiscal years beginning on or after June 15, 2010. PAETEC is currently evaluating the impact of this ASU on its financial statements.

23

In October 2009, the FASB issued ASU 2009-14, Certain Revenue Arrangements that include Software Elements. This ASU amends accounting and reporting guidance under ASC 605-985 to exclude from its scope all tangible products containing both software and non-software components that function together to deliver the product’s essential functionality. ASU 2009-14 will be effective for fiscal years beginning on or after June 15, 2010. PAETEC is currently evaluating the impact of this ASU on its financial statements.

Item 3.         Quantitative and Qualitative Disclosures About Market Risk

PAETEC is exposed to market risks in the normal course of business. PAETEC manages the sensitivity of its results of operations to these risks by maintaining an investment portfolio consisting primarily of short-term, interest-bearing securities and by entering into long-term debt obligations with appropriate pricing and terms. PAETEC does not hold or issue derivative, derivative commodity or other financial instruments for trading purposes. PAETEC does not have any material foreign currency exposure.

PAETEC’s major market risk exposure is to changing interest rates associated with borrowings the company used to fund the expansion of its business and to support its acquisition activities. The interest rates that PAETEC is able to obtain on this debt financing depend on market conditions. PAETEC’s policy is to manage interest rates through a combination of fixed-rate debt and, from time to time, the use of interest rate swap contracts to manage the company’s exposure to fluctuations in interest rates on variable-rate debt. PAETEC repaid all of its variable-rate debt outstanding under its senior secured credit facilities in January 2010 with the proceeds of the offering of $300.0 million principal amount of PAETEC’s 8 ⁷/8% senior secured notes due 2017, as described in Note 4 to the condensed consolidated financial statements appearing elsewhere in this report.
