2008 Performance Bonus Plan

Introduction

The 2008 Performance Bonus Plan is established to provide effective incentives to enhance business performance and increase shareholder value. By aligning every
employees bonus opportunity to the same goals, we encourage teamwork, cooperation and positive results for our company and the interests of our shareholders.

Plan Participants

Participants in the Plan are all full-time and part-time non-commissioned employees.

Corporate Performance Measurement

The overall company bonus
pool will be funded based on how well PAETEC performs as a company for the plan year (fiscal 2008, ending December 31, 2008). Performance measures are based on combined PAETEC and McLeodUSA financials prior to and after the transaction close
(McLeodUSA pre-closing results from January 1, 2008 through February 8, 2008 will be combined with PAETECs actual results for fiscal 2008). The pool will be funded based on performance against the following metrics:



| | - |  | 60% adjusted EBITDA
| | - |  | -------------------



| | - |  | 20% Revenue Growth
| | - |  | ------------------



| | - |  | 20% Customer Satisfaction (Net Promoter Score)
| | - |  | ----------------------------------------------

For
any funding of the bonus pool to occur, PAETEC must meet the minimum threshold level for at least one objective. For the bonus pool to be fully funded at its target level, PAETEC must achieve the target level for all three corporate
objectives. The target bonus pool may be increased, up to a stated maximum amount, or decreased if PAETEC achieves higher or lower levels of adjusted EBITDA or revenue growth than are targeted.

REVENUE GROWTH

Revenue Growth is the
overall increase in our total revenues from 2007 to 2008.

ADJUSTED EBITDA

Adjusted EBITDA stands for Earnings Before (1) Interest, Taxes, Depreciation and Amortization, (2) the other items identified as being
deducted from adjusted EBITDA in the fiscal 2008 operating budget previously approved by the Board of Directors and (3) any items that are not contemplated by the previously approved operating budget which the compensation committee of the
Board of Directors determines are appropriate for exclusion consistent with the purpose of this Plan. EBITDA results for bonus are measured after the bonus expense has been recorded.

CUSTOMER SATISFACTION

The Net
Promoter Score (NPS) assessment is the measurement for customer satisfaction.





---

The total amount of available bonus cash as determined by the achievement of the Plan targets is expressed as a
percentage of total base wages of all eligible employees. Your bonus award target is a specified percentage of your base salary based on your employment classification level within the company. Your actual bonus payout for 2008, if any, will be
determined with reference to your target bonus, but will be subject to adjustment based on your individual performance toward achievement of specified individual, department or corporate goals.

Terms and Conditions

Timing of Bonus Payments



| | A mid-year progress payment may be made after the completion of the first two fiscal quarters and funded based on estimated full-year company results. The final year-end funding of
the bonus pool is adjusted by the mid-year pool funding, if any, to reflect the actual full year company performance. Actual awards are always based on individual performance. Mid-year payments are not refundable.
