Exhibit 10.1

AGREEMENT

     THIS AGREEMENT (“Agreement”) is made as of the 21st day of November, 2008, by and between SAMUEL C. KNOCH (“Executive”) and TOLLGRADE COMMUNICATIONS, INC., a Pennsylvania corporation (the “Corporation”) (Executive and the Corporation are referred to sometimes hereinafter individually as “Party” and collectively as, the “Parties”).

W I T N E S S E T H:

     WHEREAS, Executive currently is employed by the Corporation as its Chief Financial Officer; and

     WHEREAS, the Corporation has determined it appropriate to terminate the Executive’s employment with the Corporation effective as of 11:59 p.m. on October 17, 2008 (the “Date of Termination”); and

     WHEREAS, on and subject to the terms and conditions of this Agreement, Executive and the Corporation desire to settle fully and finally all matters between them, including, without limitation, any matters that relate to Executive’s employment, the termination of that employment, or Executive’s association with the Corporation generally, whether as an employee, officer, shareholder or otherwise.

     NOW, THEREFORE, in consideration of the premises and the covenants and agreements set forth herein, the Parties hereto, intending to be legally bound, agree as follows:

     1. Termination. In connection with his termination of employment, Executive hereby resigns his position as an officer of the Corporation and any and all positions he holds with the Corporation, its subsidiary companies, or any of its other affiliates, effective as of the Date of Termination. From and after the Date of Termination, Executive shall not make any statements or engage in conduct which would lead any person or entity to believe that he is an employee, officer, consultant, agent or other authorized representative of the Corporation or any of its subsidiaries.

     2. Separation Pay.

          (a) The Corporation shall pay to Executive as separation pay the following payments, to be paid within ten days following the date of execution of this Agreement:

(i)	an amount equal to the sum of (A) Executive’s base salary through the Date of Termination to the extent not theretofore paid and (B) any vacation pay and other cash entitlements accrued by Executive as of the Date of Termination to the extent not theretofore paid; and
(ii)	twenty six (26) weeks of the Executive’s current base salary, which equals the sum of $108,584.84.

          (b) The Corporation will withhold from any amount to be paid to Executive pursuant to Section 2(a) the appropriate deductions as required by federal, state and local law, and the net amount will be paid to Executive.

          (c) The Corporation hereby acknowledges that all options to acquire stock of the Corporation held by Executive under the Corporation’s 1995 Long-Term Incentive Plan and 2006 Long-Term Incentive Plan which are vested as of the Date of Termination shall remain exercisable by Executive as provided under the terms of these plans.

     3. Continuation of Certain Benefits. From the Date of Termination and continuing until the end of the calendar month of the date twenty six (26) weeks after the date of execution of this Agreement, Executive shall be entitled to continue to receive the medical, dental and vision insurance benefits provided by the Corporation to Executive as of the Date of Termination, as though he had remained in the employment of the Corporation for such period. If for any reason, whether by law or provisions of the Corporation’s employee benefit plans or otherwise, any benefits to which Executive would be entitled under the foregoing sentence cannot be paid pursuant to such employee benefit plans, then the Corporation hereby agrees to pay to Executive the difference between (x) the benefits which Executive would have received in accordance with the foregoing and (y) the amount of benefits, if any, actually paid by the Corporation or such employee benefit plan. The Corporation shall not be required to pre-fund its obligation to pay the foregoing difference. Notwithstanding the foregoing, to the extent the Corporation, in writing, reasonably requests Executive to elect COBRA continuation coverage during such period to enable the Corporation to continue providing coverage as required hereunder, Executive shall timely do so.

     4. Outplacement Services. In addition to the separation pay and benefits described in Sections 2 and 3 hereof, the Corporation shall make available to the Executive outplacement services with Challenger, Gray & Christmas, Inc. or such other executive placement service provider as the Corporation shall determine and shall bear the expense of such services for Executive’s benefit up to a maximum of $6,000.00. The maximum period during which expenses may be incurred shall expire on December 31 of the second calendar year following the Date of Termination and any reimbursements of the Executive to be made by the Corporation for such expenses shall be made no later than December 31 of the third calendar year following the Date of Termination.

     5. Return of Corporation Property. Executive agrees that he will promptly return to the Corporation all property belonging to the Corporation and that he will otherwise comply with the Corporation’s normal employment termination procedures. By way of example only, the Corporation’s property includes, but is not limited to, items such as keys, vehicles, credit cards, cell phones, pagers, computers, all originals and copies (regardless of the form or format on which such originals and copies are maintained) of all Corporation specifications and pricing information, all customer lists and other customer-related information, all supplier lists and other supplier-related information, computer discs, tapes and other documents which relate to the business of the Corporation and/or its customers and/or its suppliers.

     6. Standstill Provision. Through the second anniversary of the Date of Termination, Executive and his Representatives (as defined below) shall not, directly or indirectly, without the prior written consent of the Board: (a) acquire or offer or agree to

acquire, directly or indirectly, by purchase or otherwise, more than five percent of any outstanding class of voting securities or securities convertible into voting securities of the Corporation, (b) propose to, or attempt to induce any other individual or entity to, enter into, directly or indirectly, any merger, consolidation, business combination, asset purchase (other than routine purchases in the ordinary course of business of product offered for sale by the Corporation) or other similar transaction involving the Corporation or any of its affiliates, (c) make, or in any way participate in any solicitation of proxies to vote, execute any consent as a Corporation shareholder, act to call a meeting of the Corporation’s shareholders, make a proposal to be acted upon by the Corporation’s shareholders or seek to advise or influence any person with respect to the voting or not voting of any securities of the Corporation, (d) form, join or in any way participate in a partnership, syndicate, joint venture or other “group” (as defined under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “1934 Act”)), with respect to any voting securities of the Corporation or transfer Executive’s voting rights with respect to any securities of the Corporation (by voting trust or otherwise), (e) otherwise act, alone or in concert with others, to seek to control or influence the management, Board or policies of the Corporation or seek a position on the Board, (f) disclose any intention, plan or arrangement inconsistent with the foregoing, or (g) advise, assist or encourage any other persons in connection with any of the foregoing. If Executive has initiated any of the foregoing activities prior to the Date of Termination, Executive shall cease, terminate and otherwise refrain from conducting such activities and shall take any and all necessary steps to effect the foregoing and any proposals made by Executive as a shareholder of the Corporation on or before the Date of Termination, are hereby withdrawn. As used herein, the term “Representative” shall include Executive’s employees, agents, investment bankers, advisors, affiliates and associates of any of the foregoing and persons under the control of any of the foregoing (as the term “affiliate,” “associate” and “control” are defined under the 1934 Act). Executive also agrees during such period not to request the Corporation or its representatives, directly or indirectly, to amend or waive any provision of this Section 6 (including this sentence) to take any action which might require the Corporation to make a public announcement regarding the possibility of a merger, consolidation, business combination or other transaction of any kind with the Executive or any affiliate of the Executive.
