Item 5.02. Compensatory Arrangements of Certain Officers.

On January 22, 2007, SIGA Technologies, Inc., a Delaware corporation (“SIGA”), entered into an Amended and Restated Employment Agreement (the “CFO Employment Agreement”) with Thomas N. Konatich, its Chief Financial Officer. The CFO Employment Agreement expires on January 22, 2009, and, unless either party provides thirty (30) days notice prior to the end of the term, shall automatically renew for additional one (1) year periods thereafter. Pursuant to the CFO Employment Agreement, SIGA agrees to pay to Mr. Konatich an annual base salary of $250,000, subject to any cost of living adjustments as may be approved by the Board of Directors of SIGA (the “Board”), and an annual cash bonus of $60,000. Mr. Konatich is also eligible to receive such additional bonus payments (in either cash or stock options) as may be approved by the Board in its sole discretion. SIGA may terminate the CFO Employment Agreement with or without cause (as such term is defined in the CFO Employment agreement), provided that upon any termination by SIGA without cause (including, without limitation, termination without cause upon a change in control, as such term is defined in the CFO Employment Agreement), or termination by Mr. Konatich for good reason (as such term is defined in the CFO Employment Agreement), SIGA will be obligated to continue to pay Mr. Konatich’s base salary for two years, and all stock options and other stock-based grants to Mr. Konatich shall immediately and irrevocably vest and become exercisable upon the date of termination and shall remain exercisable for a period of not less than one (1) year from the date of termination.

Also on January 22, 2007, SIGA entered into an Amended and Restated Employment Agreement (the “CSO Employment Agreement”) with Dr. Dennis E. Hruby, its Chief Scientific Officer. The CSO Employment Agreement expires on January 22, 2010. Pursuant to the CSO Employment Agreement, SIGA agrees to pay to Dr. Hruby an annual base salary of $250,000, subject to any cost of living adjustments as may be approved by the Board, and an annual cash bonus of no less than twenty-five percent (25%) and no more than fifty percent (50%) of Dr. Hruby’s base salary. Dr. Hruby is also eligible to receive such additional bonus payments (in either cash or stock options) as may be approved by the Board in its sole discretion. SIGA may terminate the CSO Employment Agreement with or without cause (as such term is defined in the CSO Employment Agreement), provided that upon any termination by SIGA without cause (including, without limitation, termination without cause upon a change in control, as such term is defined in the CSO Employment Agreement), or termination by Dr. Hruby for good reason (as such term is defined in the CSO Employment Agreement), SIGA will be obligated to continue to pay Dr. Hruby’s base salary for two years, and all stock options and other stock-based grants to Dr. Hruby shall immediately and irrevocably vest and become exercisable upon the date of termination and shall remain exercisable for a period of not less than two (2) years from the date of termination.
