  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On May&nbsp;12,
  2008, World Heart Corporation (the &#147;Company&#148;) received a NASDAQ Staff
  Determination Letter stating that the Company&#146;s requests for continued listing
  on The NASDAQ Capital Market has been denied. The NASDAQ noted that the Company
  did not provide a definitive plan evidencing its ability to achieve near term
  compliance with the continued listing requirements or sustain such compliance
  over an extended period of time, as required by Marketplace Rule&nbsp;</font><font size="2" style="font-size:10.0pt;">4310(c)(4)&nbsp;</font><font size="2" style="font-size:10.0pt;">(the &#147;Minimum Bid Price Rule&#148;) and
  Marketplace Rule&nbsp;</font><font size="2" style="font-size:10.0pt;">4310(c)(3), which</font><strong><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:normal;"> requires the Company to have a minimum of $2.5 million in
  stockholders&#146; equity or $35 million market value of listed securities or
  $500,000 of net income from continuing operations for the most recently
  completed fiscal year or two of the three most recently completed fiscal years.</font></b></strong><font size="2" style="font-size:10.0pt;">&#160; </font><font size="2" style="font-size:10.0pt;">Accordingly, unless the Company requests an appeal of
  this determination, trading of the Company&#146;s common stock will be suspended at
  the opening of business on May&nbsp;21, 2008, and a Form&nbsp;25-NSE will be
  filed with the Securities and Exchange Commission (the &#147;SEC&#148;) which will remove
  the Company&#146;s securities from listing and registration on The NASDAQ Stock
  Market.</font></p>

  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company may
  appeal Staff&#146;s determination to a NASDAQ Listing Qualifications Panel (the &#147;Panel&#148;),
  pursuant to the procedures set forth in the NASDAQ Marketplace Rule&nbsp;4800
  Series. A hearing request will stay the suspension of the Company&#146;s securities
  and the filing of the Form&nbsp;25-NSE pending the Panel&#146;s decision. The
  request for a hearing, which may either be an oral hearing or a hearing based
  solely on written submissions, must be received by the Hearings Department no
  later than 4:00&nbsp;P.M. Eastern Time on May&nbsp;19, 2008. If the Company
  appeals, the Company must also address its failure to comply with the </font><font size="2" style="font-size:10.0pt;">$1 million
  minimum market value requirement for its publicly held shares (&#147;MVPHS&#148;), as
  required by Marketplace Rule&nbsp;4310(c)(7)&nbsp;for continued listing on the
  NASDAQ Capital Market. </font><font size="2" style="font-size:10.0pt;">As
  of May&nbsp;9, 2008, the MVPHS of the Company totaled $857,242.</font></p>

  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On May 12, 2008, the Company announced that the Toronto Stock Exchange
  (&#147;TSX&#148;) issued a Bulletin advising it is reviewing the eligibility for
  continued listing on the TSX of the common shares of WorldHeart under sections
  709 and 710(a) of the TSX Company Manual. This review relates to the Company&#146;s
  financial condition and operating results, more specifically whether the
  Company can continue as a going concern. Further to the TSX&#146;s Remedial Review
  Process, WorldHeart has been granted 30 days in which to demonstrate compliance
  with these requirements. The Company is also permitted to make submissions
  regarding this matter at a hearing scheduled to be held on June 5, 2008. If the
  Company cannot demonstrate that it meets all TSX requirements on or before June
  11, 2008, the Company&#146;s common shares will be delisted 30 days from such date. </font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The notice also states that if at anytime, TSX becomes aware of
  additional negative developments such that the continued trading or listing of
  a Company&#146;s securities is contrary to public interest, an expedited review will
  be initiated.</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
  
  <p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On the same notice received from the TSX,&#160; the Company was&#160; informed that it improperly disseminated
  material information by failing to issue a news release immediately. The news
  release was circulated on May 9, 2008, when it should have been circulated on
  May 8, 2008 at the same time the Corporation filed its public disclosure with
  the US and Canadian securities commissions. The Corporation&#146;s management has
  made policy changes to ensure timely disclosure of material events, as required
  under section 4(b) of the TSX Company Manual.</font></p>

  3.01.  Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.
  On May 12,
  2008, World Heart Corporation (the "Company") received a NASDAQ Staff
  Determination Letter stating that the Company's requests for continued listing
  on The NASDAQ Capital Market has been denied. The NASDAQ noted that the Company
  did not provide a definitive plan evidencing its ability to achieve near term
  compliance with the continued listing requirements or sustain such compliance
  over an extended period of time, as required by Marketplace Rule
  4310(c)(4)
  (the "Minimum Bid Price Rule") and
  Marketplace Rule
  4310(c)(3), which
  requires the Company to have a minimum of $2.5 million in
  stockholders' equity or $35 million market value of listed securities or
  $500,000 of net income from continuing operations for the most recently
  completed fiscal year or two of the three most recently completed fiscal years.
  Accordingly, unless the Company requests an appeal of
  this determination, trading of the Company's common stock will be suspended at
  the opening of business on May 21, 2008, and a Form 25-NSE will be
  filed with the Securities and Exchange Commission (the "SEC") which will remove
  the Company's securities from listing and registration on The NASDAQ Stock
  Market.
  The Company may
  appeal Staff's determination to a NASDAQ Listing Qualifications Panel (the "Panel"),
  pursuant to the procedures set forth in the NASDAQ Marketplace Rule 4800
  Series. A hearing request will stay the suspension of the Company's securities
  and the filing of the Form 25-NSE pending the Panel's decision. The
  request for a hearing, which may either be an oral hearing or a hearing based
  solely on written submissions, must be received by the Hearings Department no
  later than 4:00 P.M. Eastern Time on May 19, 2008. If the Company
  appeals, the Company must also address its failure to comply with the
  $1 million
  minimum market value requirement for its publicly held shares ("MVPHS"), as
  required by Marketplace Rule 4310(c)(7) for continued listing on the
  NASDAQ Capital Market.
  As
  of May 9, 2008, the MVPHS of the Company totaled $857,242.
  On May 12, 2008, the Company announced that the Toronto Stock Exchange
  ("TSX") issued a Bulletin advising it is reviewing the eligibility for
  continued listing on the TSX of the common shares of WorldHeart under sections
  709 and 710(a) of the TSX Company Manual. This review relates to the Company's
  financial condition and operating results, more specifically whether the
  Company can continue as a going concern. Further to the TSX's Remedial Review
  Process, WorldHeart has been granted 30 days in which to demonstrate compliance
  with these requirements. The Company is also permitted to make submissions
  regarding this matter at a hearing scheduled to be held on June 5, 2008. If the
  Company cannot demonstrate that it meets all TSX requirements on or before June
  11, 2008, the Company's common shares will be delisted 30 days from such date.
  The notice also states that if at anytime, TSX becomes aware of
  additional negative developments such that the continued trading or listing of
  a Company's securities is contrary to public interest, an expedited review will
  be initiated.
  On the same notice received from the TSX,  the Company was  informed that it improperly disseminated
  material information by failing to issue a news release immediately. The news
  release was circulated on May 9, 2008, when it should have been circulated on
  May 8, 2008 at the same time the Corporation filed its public disclosure with
  the US and Canadian securities commissions. The Corporation's management has
  made policy changes to ensure timely disclosure of material events, as required
  under section 4(b) of the TSX Company Manual.
