$32,303,231

 

Item 4.

Purpose of Transaction

The Filers acquired the Stock for investment purposes. On September 29, 2008, Greg Noval sent a letter to Palo Alto Investors on behalf of the Issuer's Board of Directors responding to a letter from Palo Alto Investors sent earlier in the day, and Palo Alto Investors sent a further response to the Board. A copy of that correspondence is incorporated by reference herein as Exhibit B. On November 5, 2008, PAI LLC sent a letter to the Board, a copy of which is incorporated by reference herein as Exhibit F. On February 11, 2009, PAI LLC sent a letter to the Board questioning the timing and strategy of the Issuer’s proposed monetization of part of its Block 5(c) assets in Trinidad and Tobago (the “February 11 Letter”). On February 12, 2009, PAI LLC issued a press release including the text of the February 11 Letter and requesting additional disclosure by the Issuer with regard to its financial position and the status of that project and requesting that the Issuer hold a public conference call to update shareholders. A copy of that press release is incorporated by reference herein as Exhibit G. On February 17, 2009, PAI LLC delivered to the Issuer a requisition for a special meeting of the Issuer’s shareholders for the purpose, among other things, of removing all of the directors on the Issuer’s board of directors and replacing such directors with PAI LLC’s nominees (the “Requisition”). Also on February 17, 2009, PAI LLC issued a press release announcing that it had requisitioned a special meeting of the Issuer’s shareholders for that purpose (the “February 17 Press Release”). Once a record date and meeting date for the shareholders meeting have been established, a dissident proxy circular will be mailed to shareholders of record by PAI LLC.  The dissident proxy circular will provide details regarding each of PAI LLC's nominees to the Issuer's Board of Directors.  Shareholders are urged to carefully read the dissident proxy circular and other documents when they are available. A copy of the Requisition is incorporated by reference herein as Exhibit H, and a copy of the February 17 Press Release is incorporated by reference herein as Exhibit I. On March 10, 2009, PAI LLC sent a letter to the Board (the “March 10 Letter”) noting that no response had been provided to its February 11, 2009 inquiry regarding the Issuer’s proposed monetization of part of its Block 5(c) assets in Trinidad and Tobago and requesting a meeting with the full Board to discuss strategic and financing alternatives to monetizing the Block 5(c) assets. A copy of the March 10 Letter is attached hereto as Exhibit J and is incorporated herein by reference.

 

In pursuing their investment purposes, the Filers may from time to time further purchase, hold, vote, trade, dispose of, engage in option, swap or other derivative securities transactions with respect to or otherwise deal in the Stock at times, and in such manner, as they deem advisable to benefit from changes in the Stock's market price, changes in the Issuer's operations, business strategy or prospects, or from sale or merger of the Issuer. To evaluate such alternatives, the Filers routinely will monitor the Issuer's operations, prospects, business development, management, competitive and strategic matters, capital structure and prevailing market conditions, as well as alternative investment opportunities, the Filers' liquidity requirements and other investment considerations. Consistent with their investment research methods and evaluation criteria, the Filers may discuss such matters with the Issuer's management, Board of Directors, other shareholders, industry analysts, existing or potential strategic partners or competitors, investment and financing professionals, sources of credit and other investors. Such factors and discussions may affect materially, and result in, the Filers' modifying their ownership of the Stock, exchanging information with the Issuer pursuant to appropriate confidentiality or similar agreements, proposing changes in the Issuer's operations, governance or capitalization, or in proposing or taking one or more of the actions described in paragraphs (a) through (j) of Item 4 of Schedule 13D. The Filers may reconsider and change their plans or proposals relating to the Stock at any time.

March 10, 2009

 

Board of Directors

c/o Mr. Alexander Squires, Director and Chair of the Audit Committee

Canadian Superior Energy Inc.

3200, 500 – 4th Ave S.W.

Calgary, Alberta T2P 2V6

 

To the Board of Directors of Canadian Superior,

 

On February 11, we requested information on Canadian Superior Energy Inc.’s (“Canadian Superior” or the “Company”) plans to monetize a portion of its Block 5(c) assets in Trinidad and Tobago. We have received no response to our request, and the Company’s shareholders have not been updated in any material way on the Company’s financial position or its plans since the issuance of the September 30 financial statements on November 18, 2008, notwithstanding several significant recent developments. Since our letter, the Company’s Trinidad and Tobago assets have been placed in receivership by one of its development partners, the Company has received a repayment demand from its lender, Canadian Western Bank, and both Canadian Superior and its partner in Trinidad and Tobago, Challenger Energy Corp., have been granted protection under the Companies’ Creditors Arrangement Act in Canada.

 

In order to seek options on behalf of the Company and its shareholders, we have held discussions with various entities that could provide the capital required to cure the Company’s outstanding defaults. We are encouraged by these discussions and believe they represent realistic and viable options for the Company. We further believe these financing alternatives provide for a better solution for Canadian Superior shareholders and creditors than those publicly indicated by the Board as under consideration. We caution however that based on our views and feedback from other capital providers, such financing alternatives will require significant changes in the governance and management of the Company. We believe that such changes would be in the best long term interests of the Company and must be properly evaluated by the Board. In order for the Company to avail itself of these options in the current circumstances, the Company needs to act extremely expeditiously and move beyond the current misguided sole focus on monetizing Block 5(c).

 

We confirm that we have solidified the recruitment of our director candidates in advance of presenting our slate to the Company’s Annual General and Special Meeting of Shareholders on June 26, 2009.

 

Palo Alto Investors requests a meeting with the Board of Directors to discuss our plans to recapitalize the Company, satisfy outstanding obligations, and ensure the retention of the strategically important Block 5(c) assets in Trinidad and Tobago. We would also share with you our views on critical governance and management changes at that time.

 

In light of current circumstances, we request a phone meeting with the Board no later than Monday, March 16, 2009. We look forward to your response.

 

Sincerely,

 

David J. Anderson

Palo Alto Investors, LLC
