Payments. -------- (a) Existing Network. On May 1, 1999, and on the first day of each ---------------- month thereafter until such time as the grant and conveyance set forth in Section 1(a) hereof has terminated in its entirety, Net2Phone shall pay to IDT an Existing Network Fee (as defined below) as compensation for the grant and conveyance set forth in Section 1(a) hereof with respect to the Existing Network. As the Frontier Network is completed and delivered, Net2Phone shall have the right to require IDT to terminate, in whole or in part, any or all of the leases and other agreements set forth in Exhibit A, to the extent permitted --------- by such instruments. With respect to any termination requested by Net2Phone, the actual date such lease or other agreement is terminated shall hereinafter be referred to as the "Termination Date" with respect to such lease or other agreement. To the extent that IDT incurs any termination or cancellation charges as a result of any such lease or contract termination, Net2Phone shall reimburse IDT for such charges upon demand. The Existing Network Fee shall equal, on each date payable, the product of $60,000 multiplied by a fraction, the numerator of which is the total mileage of all circuits set forth on Exhibit A hereto except those circuits with --------- respect to which a Termination Date has occurred and the denominator of which is the total mileage of all circuits set forth on Exhibit A hereto. Ten (10) days --------- following the end of any month in which a Termination Date has occurred, IDT shall refund to Net2Phone upon the request of Net2Phone that portion of the Existing Network Fee for such month representing the per diem charge for each circuit deemed terminated during such month (based on mileage) for the number of days in such month following the Termination Date with respect to such circuit. (b) Frontier Network. Pursuant to the Frontier Agreement, IDT must ---------------- pay Frontier certain non-recurring charges for the installation of the Frontier network, some of which IDT has already paid Frontier and the remainder of which IDT will pay Frontier as the network is completed and delivered. Upon the completion and delivery of each circuit set forth on Exhibit B, Net2Phone shall --------- pay to IDT an amount equal to the non-recurring charge with respect to such circuit (as set forth on Exhibit B) plus 10%, such amount to be paid with --------- interest at 9% per annum in sixty (60) equal monthly installments commencing thirty (30) days following the completion and delivery of such circuit. Upon the completion and delivery of all of the circuits set forth on Exhibit B, the --------- amount payable by Net2Phone with respect to the non-recurring charges for the individual circuits shall be aggregated and the payments restructured so that such aggregate outstanding amount shall be paid, with interest at 9% per annum, in equal monthly payments during the Restructured Term (as defined below) commencing thirty (30) days following the completion and delivery of the final circuit of the Frontier Network. The 5 "Restructured Term" shall commence thirty (30) days following the completion and delivery of the final circuit of the Frontier Network and shall continue for that number of months equal the weighted average, rounded to the nearest whole number, of the number of months remaining in the original payment periods of the individual circuits. In addition, Net2Phone shall pay to IDT with respect to the completion and delivery of the Frontier Network an installation fee of $600,000 (the "Installation Fee"). Upon the completion and delivery of each circuit set forth on Exhibit B hereto, Net2Phone shall pay to IDT an amount equal to the product --------- of the Installation Fee multiplied by a fraction, the numerator of which is the non-recurring charge with respect to such circuit (as set forth on Exhibit B) --------- and the denominator of which is the sum of all non-recurring charges (as set forth on Exhibit B) with respect to all of the circuits of the Frontier Network --------- described on Exhibit B hereto. --------- In addition, beginning on the date hereof and continuing until the termination in its entirety of the grant and conveyance with respect to the Frontier Network, Net2Phone shall reimburse IDT an amount equal to the costs and fees IDT incurs subsequent to the date hereof with respect to the Frontier Network pursuant to the Frontier Agreement (other than the non-recurring charges), such reimbursement shall be due and payable upon payment by IDT of such costs and fees. (c) Networking Infrastructure and Network Operations Center. For ------------------------------------------------------- 24 months commencing on April 1, 1999, Net2Phone shall pay to IDT $50,000 per month as compensation for the rights of usage and enjoyment with respect to the Networking Infrastructure Equipment (as set forth in Section 1(c) hereof) and the NOC Facilities (as set forth in Section 1(e) hereof). Upon the expiration of Net2Phone's rights to use and enjoy the Networking Infrastructure Equipment and NOC Facilities pursuant to Sections 1(c) and (e) hereof, IDT hereby grants to Net2Phone the right to purchase from IDT at fair market value any such items of equipment then owned by IDT. (d) Internet Usage and Services. During the period set forth in --------------------------- Section 1(j) hereof (as extended pursuant to the terms thereof), IDT shall pay on the first day of each month (i) for each of IDT's dial-up Internet customers, $1.00 and (ii) for each of IDT's dedicated-line Internet customers, the lesser of $100.00 or 20% of the fee that IDT charges such customer. Additionally, in the case of IDT's dedicated-line customers, IDT shall pay Net2Phone 25% of all installation fees charged such customers by IDT. 3.
