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 (the “November 5 Letter”), 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 incorporated herein by reference as Exhibit J. On March 16, 2009, PAI LLC sent a letter (the “March 16 Letter”) to the Board. The March 16 Letter was sent in response to an electronic mail message sent by Greg Noval (the “March 10 Noval E-mail”) to PAI LLC responding to the March 10 Letter sent earlier in the day on March 10, 2009, and in response to a letter from C. Alexander Squires, a director and chair of the Audit Committee of the Issuer's Board of Directors (the “March 12 Board Letter”) to PAI LLC on behalf of the Issuer's Board of Directors responding to the March 10 Letter. The March 16 Letter attaches a draft term sheet that PAI LLC believes is reflective of the type of transaction that is available to the Issuer from third parties if the Issuer would be willing to enter into discussions with such third parties (the “Draft Term Sheet”) and which could serve as a potential alternative to the Issuer’s proposed sale of part of its Block 5(c) assets in Trinidad and Tobago. The March 16 Letter also attaches copies of the March 10 Noval E-Mail and the March 12 Board Letter. The foregoing descriptions of the March 16 Letter, the Draft Term Sheet, the March 10 Noval Email and the March 12 Board Letter are each qualified in their entirety by reference to the terms of such documents. A copy of the March 16 Letter is incorporated herein by reference as Exhibit K. On April 1, 2009, PAI LLC issued, via press release, an open letter (the “April 1 Letter”) to the Board of Directors and Shareholders of the Issuer describing PAI LLC’s view of the failings, misconduct and inadequate corporate governance of the current Board and again demanding that the Board be reconstituted to include truly independent Directors with relevant international oil and gas expertise. The foregoing description of the April 1 Letter is qualified in its entirety by reference to the terms of such document. A copy of the April 1 Letter is incorporated herein by reference as Exhibit L. On April 2, 2009, Mr. V. Phil Lalonde of

 

Page 7 of 14

CUSIP No. 136644101

 

Brownlee LLP wrote PAI LLC on behalf of Greg Noval, asserting, among other things, that the April 1 Letter contains statements that defame Mr. Noval. On April 3, 2009, Canadian counsel to PAI LLC, Blake, Cassels & Graydon LLP, sent a letter to Mr. Lalonde responding to his April 2, 2009 letter. The foregoing description of the April 3 Letter is qualified in its entirety by reference to the terms of such document. A copy of the April 3 Letter is incorporated herein by reference as Exhibit M. On May 15, 2009, PAI LLC commenced soliciting proxies from up to 15 shareholders of the Issuer, on a non-public basis as permitted by the Alberta Securities Commission, to vote in favor of PAI LLC's eight nominees (the “Nominees”) for election to the Issuer's Board of Directors at the June 26, 2009 annual and special meeting of the Issuers’ shareholders and to approve certain amendments to the Issuer’s By-laws, by way of a letter (the “May 15 Letter”). The May 15 Letter lists the Nominees, and attaches biographical information regarding each of the Nominees, a copy of the November 5 Letter (incorporated herein by reference as Exhibit F), a copy of the April 1 Letter (incorporated herein by reference as Exhibit L) and a form of proxy. The foregoing description of the May 15 Letter and all attachments thereto is qualified in its entirety by reference to the terms of such documents. A copy of the May 15 Letter is incorporated herein by reference as Exhibit N. On May 28, 2009, PAI LLC issued a press release (the “May 28 Press Release”) expressing PAI LLC’s disappointment and concern with the Board of Directors’ decision to delay the annual and special meeting of the Issuers’ shareholders until September 2009. The foregoing description of the May 28 Press Release is qualified in its entirety by reference to the terms of such document. A copy of the May 28 Press Release is incorporated herein by reference as Exhibit O. On June 2, 2009, PAI LLC filed a Notice of Motion (the “June 2 Notice of Motion”) with the Court of Queen’s Bench of Alberta in connection with the matter of the Issuer’s proceedings under the Canadian Companies Creditors’ Arrangement Act. The June 2 Notice of Motion seeks, among other things, an order compelling the Issuer to hold its annual general and special meeting of shareholders on June 26, 2009 or within one week thereafter and further compelling the Issuer to address the matters raised in the Requisition at such meeting. A copy of the June 2 Notice of Motion is incorporated herein by reference as Exhibit P.

 

Recent Developments: On June 17, 2009, PAI LLC issued a press release (the “June 17 Press Release”) reiterating PAI LLC’s intention to pursue changes to the Issuers’ Board of Directors, noting that PAI LLC’s nominees are willing to serve only as part of PAI LLC’s slate, and clarifying that PAI LLC’s nominees have not agreed to be appointed by the current Board of Directors of the Issuer in a partial solution that retains a majority of the existing Board of Directors of the Issuer. The foregoing description of the June 17 Press Release is qualified in its entirety by reference to the terms of such document. A copy of the June 17 Press Release is attached hereto as Exhibit Q.

 

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.

FOR IMMEDIATE RELEASE

 

Palo Alto Investors Reiterates its Intention to Pursue Changes to Canadian Superior’s Board

 

Palo Alto’s Nominees Willing to Serve Only as Part of Palo Alto’s Slate

 

Palo Alto, Calif. (June 17, 2009) – Palo Alto Investors, LLC (“Palo Alto”) today reiterates to the Board of Directors of Canadian Superior Energy Inc. (the “Company” or “Canadian Superior”) its belief that delaying changes to the Company’s Board is detrimental to the Company and its stakeholders.

Palo Alto believes that an independent and highly qualified board is an effective pre-condition of the Company’s ability to emerge from creditor protection under the Companies Creditors Arrangement Act (the “CCAA”). The Company’s previous decision to postpone the Annual General Meeting only delays the Company from implementing the changes that Palo Alto believes are necessary to compose a board that will be independent and will engage in effective governance.

David Anderson, Head of Energy Research at Palo Alto commented: “We have nominated a slate of highly qualified and independent individuals to serve as directors. The Company has publicly acknowledged that our nominees are well qualified, and has taken the time to meet with most of our nominees. The need for clarity in the CCAA process is something we and the Board agree upon, yet the Company continues to delay changes to the Board. While we applaud the departures of Greg Noval and Michael Coolen from management, we believe that is only part of the necessary transformation of the Company”.

The Company appears to agree with Palo Alto: Director Richard Watkins’ stated in his Affidavit of June 3, 2009 that “a majority of the Board expressed their belief that...(to) exit these CCAA proceedings it would require a fresh Board” but that “there had been no time for the Board to search out” candidates. However, Palo Alto has provided the independent and experienced candidates, and by the Company’s own admission, the Palo Alto nominees are well qualified. As such, Palo Alto is at a loss to understand why the Company is unwilling to define the Board now, subject to the approval of the Court and the subsequent vote of shareholders at the Annual General Meeting on September 1st. Palo Alto believes this course of action would provide the assurances required by Canadian Superior’s partners and increase the likelihood of success in the CCAA process.

In an effort to create clarity for all stakeholders in the Company’s restructuring, Palo Alto has proposed to settle its proxy contest with the Company on the basis of nominating five of its nominees to a new Board of nine directors, leaving existing Directors Richard Watkins, Jake Harp, and Alex Squires in place for continuity. Palo Alto believes this to be the best solution for all stakeholders and a necessary step to secure financing and emerge from CCAA protection. However, no agreement has been reached.

Palo Alto also wishes to clear up misconceptions that may be held by some of the Company’s Directors. Mr. Anderson noted: “Contrary to statements made by the Company in court, Palo Alto’s nominees have not agreed to be appointed by the current Board in some partial solution that retains a majority of the existing Board. The Company has implied in Court documents that it intends to select ‘several’ of the Directors from our slate to name to the Board as it finalizes the CCAA process. For the protection of our nominees and to ensure clarity for all stakeholders, all parties should be aware that no such agreement exists”. Palo Alto’s nominees have indicated that they are only prepared to serve on the Board as part of Palo Alto’s slate or should Palo Alto enter into a satisfactory settlement arrangement with the Company, as directors nominated by Palo Alto.

Mr. Anderson noted: “We and other shareholders have expressed significant concern about weak corporate governance at Canadian Superior since September 2008, which led to our decision to requisition a shareholders’ meeting to seek a change in the Board of Directors prior to the Company’s decision to seek protection under CCAA. We believe a settlement is in the best interests of all concerned, but if such an agreement cannot be reached, we fully expect to replace the entire Canadian Superior Board with the Palo Alto nominees at the September 1, 2009 AGM. We already have proxy commitments for our nominees representing approximately 28% of the Canadian Superior shares, and we have not begun any serious efforts to solicit proxies beyond the top 10 shareholders.”

Pursuant to exemptions available under applicable securities laws, Palo Alto has commenced soliciting proxies for the Meeting. A list of the independent nominees that Palo Alto has proposed for election to the Board of Directors and certain biographical information in respect of such nominees may be found in the letter from Palo Alto to certain shareholders dated May 14, 2009, a copy of which is available at www.sedar.com and in the Company’s EDGAR filings at www.sec.gov.
