directors of Network-1 Security Solutions, Inc. (the "Registrant") to serve
until his successor is duly appointed or elected. In connection therewith, the

has a 10-year term and vests at the rate of 12,500 shares per quarter beginning
on December 16, 2005. Mr. Ohana will also serve on the Compensation Committee of
the board of directors.

            In connection with Mr. Ohana's introduction of certain investors to
the Registrant with respect to its private offering of common stock and warrants

$50,000 and warrants to purchase 50,000 shares of its common stock at an
exercise price per share of $1.00. The warrants have a three year term and
vested immediately.

            Mr. Ohana is currently the Managing Partner of Parkview Ventures LLC
("Parkview"), a successor to New Media Capital LLC, a company that Mr. Ohana
founded in 1994. Parkview is engaged in merchant banking activities, including
making investments in, and providing strategic advisory services to, information
technology firms in the US and internationally. From 1999 to 2002, Mr. Ohana was
also the CEO of Inlumen, Inc. (f/k/a NewsAlert, Inc.), a company engaged in
providing private label web-based financial portals to financial institutions.
From 1987 to 1993, Mr. Ohana was an attorney at Fried Frank Harris Shriver &
