This Amendment No. 1 (this "Amendment") amends and supplements the Schedule 13D filed by Zohar Zisapel (the “Reporting Person”) with the Securities and Exchange Commission (the “SEC”) on November 20, 2008 (the “Schedule 13D”) in respect of the Ordinary Shares, NIS 0.20 par value each (“Ordinary Shares”), of RADCOM Ltd., an Israeli company (the “Issuer”).
 
Capitalized terms used herein but not otherwise defined herein shall have the meanings ascribed to such terms in the Schedule 13D.
 

Item 3. Source and Amount of Funds or Other Consideration
 
Item 3 of the Schedule 13D is hereby amended by adding the following:
 
On October 11, 2010, the Reporting Person entered into a Share and Warrant Purchase Agreement with the Issuer pursuant to which he agreed to purchase 116,959 Ordinary Shares and warrants to purchase up to 38,986 Ordinary Shares for an aggregate purchase price of $1,000,000, which was subject to the approval of the Issuer's shareholders, which was received on November 24, 2010.  See Item 6 for more information.  The Reporting Person used personal funds to pay the purchase price.
 
 
Item 4. Purpose of Transaction
 
Item 4 of the Schedule 13D is hereby amended by adding the following:

The purchase described in this Amendment was made for investment purposes. See Item 6 for more information which is incorporated by reference herein.

The Reporting Person intends to review on a continuing basis his investment in the Ordinary Shares and take such actions with respect to the investment as the Reporting Person deems appropriate in light of the circumstances existing from time to time. Such actions could include, among other things, selling additional Ordinary Shares, at any time (whether through open market transactions, privately negotiated transactions or otherwise). The Reporting Person could also determine to purchase Ordinary Shares, subject to applicable laws. Any such decision would be based on an assessment by the Reporting Person of a number of different factors, including, without limitation, the business, prospects and affairs of the Company, the market for the Ordinary Shares, the condition of the securities markets, general economic and industry conditions and other opportunities available to the Reporting Person.

Except as may be provided otherwise herein, the Reporting Person has no plans or proposals which relate to or would result in any of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D.
 
 
Item 5.  Interest in the Securities of the Issuer
 
Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

The information given herein below is based on 6,458,541 Ordinary Shares that the Issuer advised were issued and outstanding as of February 3, 2011 (including the options and warrants set forth below).
