"We were pleased that the offering was well-received by the debt market, which enabled us to complete the offering within a short timeframe," said Arunas A. Chesonis, chairman and CEO. "By extending our debt maturities, we now have enhanced financial flexibility to invest in our network, customer support, and expansion of our product suite. Over our 11 years, our conservative fiscal management has allowed PAETEC to thrive in times where others have not."

As previously announced, the Company used the net proceeds from the offering to repay a portion of the loans outstanding under PAETEC's existing senior secured term loan credit facility.

"PAETEC's history of disciplined financial management has enabled the Company to access the capital markets opportunistically," said Keith Wilson, chief financial officer. "The continued support from the financial community is a solid validation of our long term strategy and being a competitive communications market leader."

Additional information about the senior secured notes offering will be contained in the Company's current report on Form 8-K to be filed with the Securities and Exchange Commission.

Forward-Looking Statements

"Financial Services are the largest vertical industry for PAETEC, and one which we intend to continue to grow aggressively," said Tony Adornato, PAETEC's senior director of financial markets. "Transitioning the niche Trader Voice service to Speakerbus allows PAETEC to leverage its core competency by retaining the network component and divesting the day-to-day management to the product experts."

In the most recent fiscal year, these assets generated less than $1 million in revenues.

The agreement, signed in March 2009, utilizes PAETEC as one of two preferred Internet providers able to deliver service to state legislative agencies requested through DIR. In addition, PAETEC will now have the ability to directly offer services to public schools and local governments offering service from a T-1 (1.5 Mbps) to Gigabit Ethernet (1,000 Mbps), using terrestrial fiber optics or the recently expanded Fixed Wireless service.

"As a result of this agreement, Texas state agencies will now have access to PAETEC's innovative IP solutions and unmatched service," said Keith Hatley, PAETEC's vice president and general manager for Texas. "We have a long history in this state, and look forward to further expanding our presence."

PAETEC and its predecessors have been offering telecommunication services in Texas since 1995 with sales offices in Austin, Dallas, Fort Worth, Houston, San Antonio and a major employee center in the Woodlands near Houston. The company also offers personalized telecommunications solutions in 41 other states.

The EFS program takes a portion of a business' overall telecommunications profitability and applies it to a third party lease for needed hardware and software, such as a new PBX, router, copier, software applications or even office furniture. Since the program's inception ten years ago, it has financed more than $80,000,000 in equipment with the typical subsidy from $16,000 up to $500,000 or more.

"We look at every customer relationship as an opportunity to make both our companies stronger," said Mario DeRiggi, president of national sales and service. "EFS is an extension of that win-win philosophy and has clearly differentiated us and our innovative solutions in the business telecom space."

The success of the program is rooted in proprietary software that determines profit margin of an overall telecommunications solution. A portion of the profit margin is reserved to meet corporate profitability guidelines and the remainder may be used for an equipment lease subsidy. Often, the overall solution, including an EFS equipment subsidy, may deliver newer, more robust solutions with industry-leading service for less cost than their incumbent carrier.

For example, PAETEC recently designed a total communications solution for a New England business, including connecting their eight sites with a secure MPLS VPN, each with local voice via PRI ISDN lines. Utilizing the EFS program, a portion of the network subsidized over $500,000 in new equipment, including an 850-seat PBX and multiple routers.

"For most businesses in 2009, capital budgets are tighter than they have been in years." said Lisa Fitzgerald, vice president of business development. "EFS changes the paradigm. PAETEC is no longer merely a vendor, but a true partner in our customers' overall success by helping them grow their business and driving down operating and capital expenses."

PAETEC's compliance initiative was started as a result of the acquisition of US LEC in 2007 in which it became a publicly traded company, and was achieved through process modifications, validation testing and coordination between 28 internal departments. "This was a significant feat for PAETEC given the parallel integration initiatives of systems and processes over the past two years," said Arunas Chesonis, PAETEC's chairman and CEO. "As a result of the SOX project and associated process improvements, we're now a stronger company."

In 2005, the company also received national recognition from the Society of Financial Service Professionals after receiving the American Business Ethics Award in the mid-size company category (250-2,500 employees). PAETEC will be expanding its SOX compliance initiatives to encompass the 2008 acquisition of McLeod USA, with a planned completion by the end of 2009.

PAETEC's Fixed Wireless uses carrier-grade microwave equipment and consultative engineering to build reliable 'last-mile' access loops between a customer network and a local PAETEC point of presence. Wireless local loops can be provisioned at DS-3, OC-3, Fast Ethernet and Gigabit Ethernet speeds, and support the complete range of voice and IP services in the PAETEC portfolio.

The Fixed Wireless Transport solution plays an important role in PAETEC's robust Disaster Recovery and Business Continuity suite of services. By provisioning a wireless local loop, PAETEC can offer a customer complete physical infrastructure diversity within a market including termination to an alternate PAETEC Central Office. PAETEC wireless solutions are also available for enterprise customers such as universities, healthcare institutions, or professional service organizations requiring high-bandwidth point-to-point connections between buildings in a private network.

"The capability to provision wireless local loops clearly sets PAETEC apart from its competitors," said John Chapman, senior vice president of marketing. "Our growing business continuity portfolio enables us to deliver unique transport solutions like Fixed Wireless giving customers a new level of diversity."

PAETEC's expansion of its Fixed Wireless product suite comes as the result of the acquisition of MPX, Inc., a New York based company with 10 years of experience in licensed fixed wireless system engineering and field integrations. The 2008 acquisition brought a strong list of customers utilizing this product today.

"We have worked with a number of businesses across the U.S. as an alternative to fiber," said Mark Palvino, vice president of PAETEC Wireless. "These customers require very high bandwidth and have a low tolerance for interruptions. Fixed Wireless delivers them the speed and continuity they need."

"We strive every day to assist people in becoming productive citizens, but the new costs for the Citizenship Test can be prohibitive for many of our learners," said Bob Mahar, executive director for LVR. "We commend PAETEC and other private donors for helping to make up the difference."

The scholarship fund is available to learners enrolled in the literacy program who are planning to take the test within three months. LVR volunteers will review the applications for the scholarships and choose the recipients of the $200 scholarship.

SIP Trunking, short for Session Initiation Protocol, converges data, voice, and Internet communications onto a single high-speed, pure-IP circuit that establishes the foundation for advanced communications capabilities. Certifying the interoperability of communications equipment and IP networks makes it easier for businesses to achieve the full benefits of advanced collaboration capabilities. In addition, certification across PAETEC's national geographic coverage means multi-site customers can link their locations coast-to-coast using a single network provider with ease.

"Especially in times like these, business-class customers must keep a sharp watch on expenses while also maintaining the quality of customer service," said John Chapman, senior vice president of marketing. "PAETEC's relationship with Cisco can help businesses address both priorities simultaneously."

"The integration of PAETEC's SIP Trunking Service into the Cisco Configuration Assistant will help ensure a seamless setup and integration of Cisco's Smart Business Communications Systems," said Mark Monday, vice president, Small Business Solutions Business Unit, Cisco. "Businesses that take advantage of the pairing of IP-based platforms with SIP-based transport will be able to realize a simple, affordable, easy-to-manage unified communications solution with the ability to deploy hosted applications and advanced services." Laboratory interoperability testing is designed to simulate the most typically used configurations.

With Dynamic IP services from PAETEC, customers can choose the bandwidth that truly meets their requirements, from a T-1 to DS-3, Ethernet or greater. Customers can also manage their own service in real-time through PAETEC's secure online customer portal.

Other benefits of PAETEC's SIP Trunking service include:

• Standard G.729 Compression that can significantly increase the number of high-quality voice circuits within a single T-1 compared with traditional Primary Rate Interfaces (PRIs)
• Quality of Service (QoS) capabilities that prioritize voice signals over data. When no voice signals are present, all available bandwidth can be used for data.
• VoIP-to-TDM voice conversion provided within the network, requiring less equipment for the end user.
• Unlimited and free site-to-site calling between Dynamic IP locations.
• Site-to-site voice and data sharing that is protected from the public Internet.

PAETEC Dynamic IP with SIP Trunking service earned Telephony magazine's Most Innovative Product award for 2008. For more information on PAETEC, visit www.paetec.com.
