(5) Payments/Payment Terms. (a) Within five (5) business days of execution of this Agreement, D-Link will pay Network-1 an upfront payment of $100,000. (b) In further consideration for the license granted herein and except as otherwise stated herein, commencing on the Effective Date and provided that the registration of '930 Patent with the U.S. Patent Office is duly maintained by Network-1, with respect to 4 CONFIDENTIAL Licensed Products, D-Link will pay to Network-1 a running royalty of 3.25% (the "Royalty Rate") of D-Link's Net Sales for the sale of Licensed Products (except PoE Adapters), and 5% of D-Link's Net Sales from the sale of PoE Adapters (the "Adapter Royalty Rate"), for all sales that occur on or after the Effective Date. Royalties shall be paid monthly no later than twenty (20) days after the first day of each month, based on the preceding month's Net Sales. Royalties shall be submitted with a Monthly Royalty Report, in the form of Exhibit C, showing all Licensed Products sold by D-Link in the immediately preceding month. The Royalty Report will also list any additional products that fall within the scope of Licensed Products and that are to be added to Exhibit B. (c) Beginning March 31, 2008, D-Link shall be entitled to pay the lower of the Royalty Rate/Adapter Royalty Rate (hereinafter collectively referred to as "Rate") in 5(b) and the royalty rate that may be Network-1's RAND Royalty Rate in effect at that time. If D-Link chooses to accept such RAND Royalty Rate, its royalty payments under this Section 5(d) shall be calculated using the same methodology as the royalty payments in the license agreement that triggered the adjustment described herein and shall apply to all Licensed Products. The Rate can be reduced quarterly throughout the term of this Agreement to reflect the then current RAND Royalty Rate. Network-1 agrees that as of the Effective Date, the Royalty Rate set forth herein is Network-1's initial RAND Royalty Rate. If there is any change to the RAND Royalty Rate after the Effective Date, Network-1 shall provide such changes to D-Link in writing on a quarterly basis. It is understood and agreed that the RAND Royalty Rate may include rates that vary according to units of licensed products shipped and any adjustments to the Rate will be at a rate consistent with similarly situated companies and volumes (units of licensed products sold) under the Network-1 RAND Licensing Program. (d) D-Link shall submit to Network-I a semi-annual royalty report ("Royalty Report") within thirty (30) days after the end of every six month anniversary of the Effective Date of the Agreement. The Royalty Report shall be certified by an appropriate responsible employee of D-Link setting forth the amount of the royalties and calculation thereof for the reported period regardless of whether or not any payment is due. The Royalty Report will also list any additional products that fall within the scope of Licensed Products and that are to be added to Exhibit B. (e) If the '930 Patent is found to be invalid by (i) a court of competent jurisdiction, (ii) a final decision of the U.S. Patent and Trademark Office after a re-examination, or (iii) the International Trade Commission, then D-Link shall be entitled to cease making royalty payments; provided, however, that in the event such finding is overturned by the U.S. Court of Appeals for the Federal Circuit or other higher court of competent jurisdiction, D-Link shall be responsible for back royalties plus interest at the Prime Rate as reflected in the Wall Street Journal as of the date of the ruling of' invalidity. Network-1 will provide D-Link with written notice of such a finding of invalidity (or any decision overturning such a finding) within twenty (20) days of the date of such decision. (f) In the event a third party's PoE products that comply with the IEEE PoE Standards are found not to infringe the '930 Patent by a court of competent jurisdiction (expressly including the International Trade Commission), D-Link may provide notice to 5 CONFIDENTIAL Network-1 that such finding could result in the termination of D-Link's obligation to pay royalties under the Agreement, and D-Link may provide notice to Network-1 that it intends to cease making royalty payments for Licensed Products of comparable form and function as the PoE products found not to infringe the '930 Patent. Network-1 shall provide D-Link with written notice of such a finding of non-infringement as soon as reasonably practicable. If the parties disagree with the effect the court's ruling has on D-Link's obligation to pay royalties under this Agreement, the parties may submit the issue whether the non-infringement finding would be applicable to the Licensed Products to a mutually agreed upon mediator followed, if necessary, by binding arbitration pursuant to the rules of the American Arbitration Association. In the event that the Arbitration Panel makes an award that said non-infringement finding applies to D-Link or the Licensed Products, then D-Link may cease further royalty payments for sales of the Licensed Product; provided, however, in the event such non infringement ruling is overturned by the U.S. Court of Appeals for the Federal Circuit or other higher court of competent jurisdiction, the obligations to pay royalties will be reinstated, with interest at the Prime Rate as reflected in the WALL STREET JOURNAL as of the date of such ruling of non-infringement, and this Agreement will remain in full force and effect irrespective of any prior arbitration ruling to the contrary. Network-1 will provide D-Link with written notice of such ruling within twenty (20) days of its issuance. (g) Irrespective of any ruling of a court, administrative body or arbitral tribunal, no royalties paid by D-Link shall be subject to refund except (1) overpayments made in error and identified by D-Link within twelve (12) months of actual or constructive notice of erroneous payment, whichever is later, (2) if D-Link is not given timely notice of a finding of non-infringement or invalidity and the parties do not take the dispute to mediation and binding arbitration, pursuant to Section 5(f), then D-Link may claim a refund payment for the delay period from the date of required notice until D-Link became aware of such non-infringement or invalidity decision, (3) in the event that mediation or arbitration requested under Section 5(f) is not completed (e.g., the arbitration award is not issued) within 120 days of a notice of intention to cease royalty payments by D-Link, then D-Link shall be entitled to a refund of all royalties paid after said 120-day period but only in the event a determination is made at mediation or arbitration that the third party ruling relieves D-Link of its obligation to pay further royalties. Any refund that D-Link may be entitled to pursuant to Sections 5(g)(l)(2) or (3) above, shall be taken as a credit in a subsequent Monthly Royalty Report; provided, however that if no further royalties are due under this agreement D-Link shall receive a refund instead of a credit. (h) Payments when provided for in this Agreement shall, when overdue, bear interest compounded monthly (prorated for periods of time less than one month) at an annualized rate of three percent (3%) over the prime rate quoted by the Wall Street Journal, in New York, on the date that the payment is due, for each month during the delinquency. If the amount of such charge exceeds the maximum permitted by law, such charge shall be reduced to such maximum. 6 CONFIDENTIAL (6) Representations and Warranties. (a).

(OTC BB: NSSI) today announced that it has agreed to final licensing terms with D-Link Corporation and D-Link Systems ("D-Link") as part of a definitive Settlement Agreement of its patent infringement litigation against D-Link in the United States District Court for the Eastern District of Texas, Tyler Division for infringement of Network-1's Remote Power Patent (U.S. Patent No. 6,218,930). The license terms include the agreement by D-Link to license the Remote Power Patent for its full term which expires in March 2020, and the payment of monthly royalty payments (beginning as of May 26, 2007) based upon a running royalty rate of 3.25% of the net sales of D-Link branded Power over Ethernet products, including those products which comply with the IEEE 802.3af and 802.3at Standards. The royalty rate is subject to adjustment beginning the second quarter of 2008 to a royalty rate consistent with other similarly situated licensees of the Remote Power Patent that may vary according to units and volumes of licensed products sold. In addition, D-Link has agreed to an upfront payment to Network-1 of $100,000. The products covered by the settlement include D-Link Power over Ethernet enabled switches, wireless access points, and network security cameras, among others. As a result of the definitive Settlement Agreement, all claims and counterclaims in the litigation currently pending in the Eastern District of Texas have been dismissed with prejudice. "We are extremely pleased at the outcome of this litigation and having D-Link as the first licensee of our Remote Power Patent," commented Corey M. Horowitz, Chairman and Chief Executive Officer of Network-1. "This outcome is consistent with Network-1's goal of making licenses available to the technologies covered by the Remote Power Patent to the Power over Ethernet industry in a manner that promotes the widespread adoption of this important industry standard". The Remote Power Patent relates to, among other things, the delivery of power over Ethernet cables in order to remotely power network connected devices including, among others, wireless switches, wireless access points, REID card readers, VoIP telephones and network cameras. In June 2003, the Institute of Electrical and Electronic Engineers (IEEE) approved the 802.3af Power over Ethernet ("PoE") standard which has led to the rapid adoption of PoE. The IEEE is currently working on the 802.3at Power over Ethernet Plus (PoE Plus) Standard which will increase the maximum power delivered to network devices of up to 60 watts from the current 15 watts under 802.3af.
