EXHIBIT 10.77

SEVERANCE AGREEMENT

THIS SEVERANCE AGREEMENT (“Agreement”) by and between SalesLink Corporation, a Delaware corporation with principal executive offices located at 425 Medford Street, Charlestown, MA 02129 (the “Company”), and Bryce Boothby (the “Executive”), is made as of April 27, 2001.

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that the Executive will play a critical role in the operations of the Company; and

WHEREAS, the Board has determined that appropriate steps should be taken to reinforce and encourage the continued employment and dedication of the Executive;

NOW, THEREFORE, as an inducement for and in consideration of the Executive remaining in its employ, the Company agrees that the Executive shall receive the benefits set forth in this Agreement in the circumstances described below.

1.        Not A Guarantee of Employment.  The Executive acknowledges that this Agreement does not constitute a guarantee of employment or impose on the Company any obligation to retain the Executive as an employee and that this Agreement does not prevent the Executive from terminating his employment. The Executive understands and acknowledges that he is an employee at will and that either he or the Company may terminate the employment relationship between them at any time and for any lawful reason.

2.        Severance Pay and Option Acceleration under Certain Circumstances Following a Change of Control.  In the event a Change in Control (as defined below) occurs and, within one year thereafter, the employment of the Executive is terminated (i) by the Company for a reason other than for Cause (as defined below) or (ii) by the Executive for Good Reason (as defined below), then the Executive shall be eligible for severance pay in accordance with such policies as the Board may establish from time to time, provided he executes a copy of the Company’s standard severance agreement and release following his last day of employment with the Company. Such severance pay shall amount to no less than the equivalent of six months’ base wages, less applicable taxes and withholding, and shall be paid in installments, on a semi-monthly basis, in accordance with the Company’s regular payroll practices.

Additionally, in the event a Change in Control occurs and, within one year thereafter, the employment of the Executive is terminated (i) by the Company for a reason other than for Cause or (ii) by the Executive for Good Reason, with respect to the option to purchase shares of common stock of the Company granted by the Company on April 27, 2001 to, and then held by, the Executive, on the Executive’s last day of employment with the Company, twenty-five (25) percent of the original number of shares subject to such option shall be accelerated such that the Executive shall be entitled to exercise the option (in accordance with the exercise terms and conditions set forth in the option

agreement and/or plan pursuant to which such option was granted) to the same extent as he would have had the accelerated portion of the option vested in accordance with the schedule established in the applicable stock option grant.

3.        Sole Remedy.  The payment to the Executive of the amounts payable under Section 2 (and applicable acceleration of options) along with payment of any accrued but unused vacation pay shall constitute the sole remedy of the Executive in the event of a termination of the Executive’s employment with the Company following a Change of Control.
