NEW YORK, Jan. 29, 2013 /PRNewswire/ --Network-1 Security Solutions, Inc.
(the "Company") (OTCBB: NSSI) announced today that its Board of Directors has
authorized an increase to its previously announced share repurchase program
pursuant to Rule 10(b)-18 permitting the Company to repurchase up to an
additional $1,000,000 (for a total of up to $5,000,000) in shares of the
Company's common stock over the next twelve months. On August 14, 2011, the
Company announced a share repurchase program to purchase up to $2,000,000 of
its common stock, which was increased to an aggregate of $4,000,000 on
February 2, 2012. To date, the Company has repurchased approximately
2,600,000 shares under its program at an average price of $ 1.24 per share.

The Common Stock may be repurchased from time to time in open market
transactions or privately negotiated transactions in the Company's discretion.
The timing and amount of shares repurchased will be determined by the
Company's management based on its evaluation of market conditions and other
factors. The repurchase program may be increased, suspended or discontinued
at any time.

The share repurchase program was approved by the Company's Board of Directors
as part of its ongoing consideration of alternative methods to take advantage
of the Company's strong cash position. The Board of Directors believes that
increasing the share repurchase program at this time is in the best interests
of the Company and its shareholders, and will not impact the Company's ability
to execute its growth plans.
