In lieu of the obligation of VTEL to refund to Intel the amount of $901,170 due and owing by VTEL to Intel under the Development and License Agreement in respect of unexpended NRE funding, VTEL and Intel have agreed that VTEL shall issue to Intel 155,040 shares of its common stock in full satisfaction of VTEL's obligation to refund $901,170 to Intel as aforesaid and the parties have reached the agreements herein contained. NOW, THEREFORE, in consideration of the forgoing recitals and mutual promises hereinafter set forth and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows: 1. Issuance of Stock in Satisfaction of Unfunded NRE Reimbursement. --------------------------------------------------------------- Within ten (10) business days of the execution of this Agreement, VTEL shall cause to be delivered to Intel a stock certificate representing 155,040 shares of VTEL common stock (the "Shares"). 2.

Upon receipt of such stock certificate, Intel shall promptly return to VTEL the Letter of Credit (as defined in the Development and License Agreement), which as of the date hereof has an undrawn face amount of $888,670, and VTEL's obligations to maintain such standby Letter of Credit under the terms of the Development and License Agreement shall terminate.
