*   The reporting person is Xmark  Asset  Management,  LLC  ("XAM"),  a New York
limited liability company.  XAM's interest in the securities  reported herein is
limited to its  pecuniary  interest,  if any,  in Xmark Fund,  L.P.,  a Delaware
limited  partnership  ("Xmark  LP"),  and Xmark  Fund,  Ltd.,  a Cayman  Islands
exempted company ("Xmark Ltd").

Xmark LP is the holder of: (i) 679,865  shares (the "Xmark LP Shares") of Common
Stock, par value $0.01 per share (the "Common Stock"), of Antares Pharma,  Inc.,
a Minnesota  corporation  (the  "Company");  (ii)  warrants  (the "2003 Xmark LP
Warrants") which,  subject to certain exercise  restrictions  contained therein,
entitle  Xmark LP to purchase  an  aggregate  of up to 238,125  shares of Common
Stock at an  exercise  price of $1.00  per share  (the  "2003  Xmark LP  Warrant
Shares"), which exercise price is subject to adjustment as set forth in the 2003
Xmark LP  Warrants;  and (iii)  44,927  shares (the "Xmark LP Series D Preferred
Shares") of the Company's Series D Convertible  Preferred Stock, par value $0.01
per share (the  "Series D  Preferred  Stock").  Subject to certain  restrictions
contained in the Company's  Certificate  of  Designations  of Series D Preferred
Stock (the  "Certificate  of  Designations"),  each Xmark LP Series D  Preferred
Share is  convertible  into ten  shares of Common  Stock,  for an  aggregate  of
449,270 shares of Common Stock (the "Xmark LP Conversion Shares").

Xmark Ltd is the holder of: (i) 1,808,878 shares of Common Stock (the "Xmark Ltd
Shares," and together  with the Xmark LP Shares,  the  "Shares");  (ii) warrants
(the "2003 Xmark Ltd  Warrants,"  and together  with the 2003 Xmark LP Warrants,
the "2003 Warrants") which, subject to certain exercise  restrictions  contained
therein,  entitle Xmark Ltd to purchase an aggregate of up to 511,875  shares of
Common  Stock at an  exercise  price of $1.00 per  share  (the  "2003  Xmark Ltd




Warrant  Shares,"  and  together  the 2003  Xmark LP Warrant  Shares,  the "2003
Warrant Shares"),  which exercise price is subject to adjustment as set forth in
the 2003 Xmark Ltd Warrant; and (iii) 135,234 shares of Series D Preferred Stock
(the  "Xmark Ltd Series D  Preferred  Shares",  and  together  with the Xmark LP
Series  D  Preferred  Shares,  the  "Preferred  Shares").   Subject  to  certain
restrictions contained in the Certificate of Designations, each Xmark Ltd Series
D  Preferred  Share is  convertible  into ten  shares  of Common  Stock,  for an
aggregate  of  1,352,340  shares of Common  Stock  (the  "Xmark  Ltd  Conversion
Shares," and  together  with the Xmark LP  Conversion  Shares,  the  "Conversion
Shares").

Prior to March 1, 2004,  Xmark LP was the holder of warrants (the "Initial Xmark
LP Warrants") which, subject to certain exercise restrictions contained therein,
entitled  Xmark LP to purchase up to an  aggregate  of 569,325  shares of Common
Stock at an  exercise  price of $0.28 per share (the  "Initial  Xmark LP Warrant
Shares"),  and Xmark Ltd was the  holder of  warrants  (the  "Initial  Xmark Ltd
Warrants",  and  together  with the  Initial  Xmark LP  Warrants,  the  "Initial
Warrants") which,  subject to certain exercise  restrictions  contained therein,
entitled Xmark Ltd to purchase an aggregate of up to 1,680,675  shares of Common
Stock at an exercise  price of $0.28 per share (the  "Initial  Xmark Ltd Warrant
Shares," and together  with the Initial  Xmark LP Warrant  Shares,  the "Initial
Warrant  Shares"),  which exercise prices are subject to adjustment as set forth
in the Initial Warrants.

Each  of the  2003  Warrants,  the  Initial  Warrants  and  the  Certificate  of
Designations,  provides  that in no event shall such  warrant or such  Preferred
Shares,  be exercisable for, or convertible  into, shares of Common Stock to the
extent that the issuance of 2003 Warrant  Shares,  Initial Warrant Shares and/or
Conversion Shares  thereunder,  taking into account the Shares,  would result in
the  "beneficial  ownership"  (as  defined  in Section  13(d) of the  Securities
Exchange Act of 1934, as amended, and Regulations 13D-G thereunder) by Xmark LP,
Xmark Ltd,  or their  affiliates,  of more than  9.99% of the Common  Stock (the
"Issuance  Limitation").  Such  Issuance  Limitation  may be  waived by Xmark LP
and/or  Xmark Ltd upon 61 days  written  notice  to the  Company.  The  Issuance
Limitation with respect to the Initial Warrants was waived on December 30, 2003.
As a result of that  waiver,  the Issuance  Limitation  with respect to the 2003
Warrants and the Conversion Shares is currently ineffective.

On March 1, 2004,  Xmark LP and Xmark Ltd fully  exercised the Initial  Warrants
and were issued the Initial Warrant Shares. As a result, on March 1, 2004, Xmark
LP became the holder of an additional  569,325 shares of Common Stock, and Xmark
Ltd became the holder of an additional 1,680,675 shares of Common Stock.

XAM serves as  investment  manager  for each of Xmark LP and Xmark Ltd.  In such
capacity,  XAM  possesses  the power to vote and direct the  disposition  of all
securities  held by Xmark LP and Xmark  Ltd.  Thus,  as of May 14,  2004 for the
purposes  of Reg.  Section  240.13d-3,  XAM may be  deemed to  beneficially  own
5,040,353 shares of Common Stock, or 12.4% of the Common Stock deemed issued and
outstanding as of that date.

The total number of shares of Common Stock  beneficially owned by XAM, including
2003  Warrant  Shares  and  Conversion  Shares  is  5,040,353  or  12.4%  of the
outstanding  shares of Common  Stock as of May 14,  2004  (based on  information
provided by the  Company).  This does not include  30,000 shares of Common Stock
and  Warrants to acquire  349,999  shares of Common  Stock  owned by  Sabbatical
Ventures,  LLC, a Delaware limited  liability company  ("Sabbatical").  Nor does
this include the 20,000  shares of Common Stock and warrants to acquire  700,001
shares  of  Common  Stock  owned by  certain  employees  of XAM.  Sabbatical  is
controlled  by  Mitchell  D. Kaye.  Mr.  Kaye is Manager of XAM.  XAM  disclaims
beneficial   ownership  of  the  securities  held  by  these  employees  and  by
Sabbatical. Sabbatical disclaims beneficial ownership of securities beneficially
owned by each of XAM,  Xmark LP and Xmark  Ltd.  XAM  acquired  these  shares of
Common Stock and the warrants to acquire  these shares of Common Stock that were
distributed  to  its  employees  and  to  Sabbatical  pursuant  to  an  Advisory
Agreement,  dated as of January 15, 2003. Mr. Kaye's  interest in the securities
reported herein is limited to his pecuniary interest in XAM, Xmark LP, Xmark Ltd
and Sabbatical, if any.





Item 5.   Interest in Securities of the Issuer.
          ------------------------------------

          Based  upon  the  Company's  Quarterly  Report  on Form  10-Q  for the
quarterly  period ended March 31, 2004, as of May 10, 2004 there were 37,943,796
shares of Common Stock issued and outstanding.  As of May 14, 2004, Xmark LP and
Xmark Ltd own, in aggregate,  2,488,743  shares of Common  Stock.  As of May 14,
2004, based on the December 30, 2003 waiver of the Issuance Limitation, Xmark LP
and Xmark Ltd beneficially  own 5,040,353  shares of Common Stock,  inclusive of
the aforesaid 2,488,743 shares of Common Stock.

          XAM  possesses  sole power to vote and direct the  disposition  of all
securities  held by Xmark LP and Xmark Ltd.  Thus,  as of May 14, 2004,  for the
purposes of Reg.  Section  240.13d-3,  XAM, the  investment  manager for each of
Xmark LP and Xmark Ltd, may be deemed to  beneficially  own 5,040,353  shares of
Common  Stock,  or 12.4%  of the  shares  of  Common  Stock  deemed  issued  and
outstanding as of that date. This does not include 30,000 shares of Common Stock
and  Warrants to acquire  349,999  shares of Common  Stock  owned by  Sabbatical
Ventures,  LLC, a Delaware limited  liability company  ("Sabbatical").  Nor does
this include the 20,000  shares of Common Stock and warrants to acquire  700,001
shares  of  Common  Stock  owned by  certain  employees  of XAM.  Sabbatical  is
controlled  by  Mitchell  D. Kaye.  Mr.  Kaye is Manager of XAM.  XAM  disclaims
beneficial   ownership  of  the  securities  held  by  these  employees  and  by
Sabbatical. Sabbatical disclaims beneficial ownership of securities beneficially
owned by each of XAM,  Xmark LP and Xmark  Ltd.  XAM  acquired  these  shares of
Common Stock and the warrants to acquire  these shares of Common Stock that were
distributed  to  its  employees  and  to  Sabbatical  pursuant  to  an  Advisory
Agreement,  dated as of January 15, 2003. Mr. Kaye's  interest in the securities
reported herein is limited to his pecuniary interest in XAM, Xmark LP, Xmark Ltd
and Sabbatical, if any.

          In addition to the  transactions  described above, the following table
