# Section 302 CFO
Certification

I, Lawrence M. Christian, certify that:

1.    
          I have reviewed this annual report on Form 10-K/A of Antares Pharma, Inc.;

2.    
          Based on my knowledge, this report does not contain any untrue statement of a
material
fact or omit to state a material fact necessary to         make the statements made, in light of
the circumstances under which such statements were made, not misleading with respect to       
the period covered by this report; and

3.      
               Based on my knowledge, the financial statements, and other financial information
               included in this report, fairly present in all material         respects the financial
               condition, results of operations and cash flows of the registrant as of, and
               for, the periods presented in this          report.

4.     
               The registrants other certifying officer and I are responsible for
               establishing and maintaining disclosure controls and procedures (as         defined in
               Exchange Act Rules 13a-15(e) and  15d-15(e)) for the registrant and have:

a)        

           designed such disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under our                     
supervision, to ensure that material
          information relating to the registrant, including its consolidated subsidiaries,
          is made known to                     
us by others within those entities, particularly during the
          period in which this report is being prepared;

b)        

           evaluated the effectiveness of the registrants disclosure controls and
          procedures and presented in this report our conclusions                     about the effectiveness
          of the disclosure controls and procedures, as of the end of the period covered
          by this report based                     on such evaluation; and

c)        
           disclosed in this report any change in the registrants internal control
          over financial reporting that occurred during the registrants                    most recent
          fiscal year that has materially affected, or is reasonably likely to materially
          affect, the registrants internal control                     over financial reporting; and

5.    
               The registrants other certifying officer and I have disclosed, based on
               our most recent evaluation of internal control over financial 
        reporting, to the
               registrants auditors and the audit committee of registrants board of
               directors (or persons performing the equivalent 
        functions):

a)        
           all significant deficiencies and material weaknesses in the design or operation
          of internal control over financial reporting which are                     reasonably likely to
          adversely affect the
registrants ability to record, process, summarize and
          report financial information; and

b)        
       any fraud, whether or not material, that involves management or other employees
          who have a significant role in the registrants                     internal control over
          financial reporting.
