      August
      9, 2006, Michael S. Weiss, Chairman and Chief Executive Officer of Keryx,
      adopted a Rule 10b5-1 trading plan (the &#8220;Plan&#8221;) with a brokerage firm to
      exercise stock options issued to Mr. Weiss pursuant to his employment agreement
      and Keryx&#8217;s stock option plans and to sell the common stock underlying such
      options. Mr. Weiss entered into the Plan to facilitate the exercise of stock
      options and as part of his personal long-term investment strategy for asset
      diversification and liquidity. Mr. Weiss has no control over the timing of
      the
      option exercises or stock sales under the Plan. The Plan replaces and supersedes
      a plan originally filed on December 30, 2005. No shares will be exercised and
      sold under the Plan until October 15, 2006. Thereafter, pursuant to the Plan,
      200,000 stock options will be exercised and shares of the underlying common
      stock will be sold upon the stock price reaching four pre-set price targets
      of
      $15, $18, $20 and $25. The next tranche of stock options will not be exercised
      and sold until the next price target is reached.</font></div>

      stock options representing 800,000 shares are available to be exercised under
      the Plan. The number of employee stock options available to be exercised
      represents approximately 12% of Mr. Weiss&#8217;s holdings. The Plan is scheduled to
      terminate in October 2008, whether or not the total number of shares is sold.

Item
      8.01. Other Events.
On
      August
      9, 2006, Michael S. Weiss, Chairman and Chief Executive Officer of Keryx,
      adopted a Rule 10b5-1 trading plan (the "Plan") with a brokerage firm to
      exercise stock options issued to Mr. Weiss pursuant to his employment agreement
      and Keryx's stock option plans and to sell the common stock underlying such
      options. Mr. Weiss entered into the Plan to facilitate the exercise of stock
      options and as part of his personal long-term investment strategy for asset
      diversification and liquidity. Mr. Weiss has no control over the timing of
      the
      option exercises or stock sales under the Plan. The Plan replaces and supersedes
      a plan originally filed on December 30, 2005. No shares will be exercised and
      sold under the Plan until October 15, 2006. Thereafter, pursuant to the Plan,
      200,000 stock options will be exercised and shares of the underlying common
      stock will be sold upon the stock price reaching four pre-set price targets
      of
      $15, $18, $20 and $25. The next tranche of stock options will not be exercised
      and sold until the next price target is reached.
Employee
      stock options representing 800,000 shares are available to be exercised under
      the Plan. The number of employee stock options available to be exercised
      represents approximately 12% of Mr. Weiss's holdings. The Plan is scheduled to
      terminate in October 2008, whether or not the total number of shares is sold.
Any
      transactions under the Plan will be reported by Mr. Weiss through Form 4 filings
      with the Securities and Exchange Commission. The Plan is intended to comply
      with
      Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and the
      Company's insider trading policy.
