On February 20, 2014, the Reporting Persons sent a letter to the Board of Directors, the Governance and Nominating Committee of the Board of Directors and the Secretary of the Issuer formally requesting that the Issuer include two (2) nominees (the “Nominees”) identified by the Reporting Persons in the Issuer’s slate of directors at the forthcoming 2014 annual meeting of stockholders (the “Annual Meeting”) and, in addition and in the alternative, indicating its intent to nominate the Nominees to the Board of Directors at the Annual Meeting. A copy of the notification letter delivered to the Issuer is filed as Exhibit 99.1 hereto and is incorporated herein by reference.

The Reporting Persons reserve their rights to make alternative plans or proposals in the future or take any other steps to enhance the value of their investment. The Reporting Persons further reserve the right to increase, decrease or eliminate their investment in the Issuer or take any other action relative thereto.

Stockholders are advised to read the proxy statement and other documents related to solicitation of proxies by Talisman Group Investments, L.L.C. and its affiliates from the stockholders of Endeavour International Corporation for use at the 2014 annual meeting of Endeavour International Corporation at such time as they may be available because they will contain important information.

Except as set forth above, the Reporting Persons currently have no plan or proposals with respect to any of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D. The Reporting Persons may, however, take such actions in the future.

The information set forth and/or incorporated by reference in Items 2, 3 and 4 is hereby incorporated by reference into this Item 5.

(a) The aggregate number of Common Stock and the percentage of total outstanding Common Stock beneficially owned by the Reporting Persons is set forth below. References to percentage ownerships of Common Stock in this Statement are based upon 48,820,570 shares of Common Stock outstanding, which includes 47,200,000 shares of Common Stock stated to be outstanding in the Issuer’s Quarterly Report on Form 10-Q as filed with the Securities and Exchange Commission on November 12, 2013, and 1,620,570 shares of Common Stock issuable upon conversion of the Convertible Notes. The Reporting Persons may be deemed to beneficially own an aggregate of 7,620,570 shares of Common Stock (consisting of 2,000,000 shares of Common Stock, 1,620,570 shares of Common Stock issuable upon conversion of the Convertible Notes, and 4,000,000 shares of Common Stock deliverable upon exercise of the Options that will be exercisable by the Reporting Persons within 60 days of February 20, 2014), which constitutes 15.61% of the Common Stock, calculated in accordance with Rule 13d-3 under the Act. The filing of this Statement shall not be construed as an admission that a Reporting Person beneficially owns those shares held by any other Reporting Person.

TRC Master Fund beneficially owns 7,620,570 shares of Common Stock, which represents approximately 15.61% of the outstanding Common Stock calculated in accordance with the requirements of Rule 13d-3 under the Act.

The General Partner, as the general partner of TRC Master Fund, may be deemed to beneficially own 7,620,570 shares of Common Stock, which represents approximately 15.61% of the outstanding Common Stock calculated in accordance with the requirements of Rule 13d-3 under the Act.

The Manager, as the investment advisor of TRC Master Fund, may be deemed to beneficially own 7,620,570 shares of Common Stock, which represents approximately 15.61% of the outstanding Common Stock calculated in accordance with the requirements of Rule 13d-3 under the Act.

The InvestCo, which is the sole owner of the Holdco, may be deemed to beneficially own 7,620,570 shares of Common Stock, which represents approximately 15.61% of the outstanding Common Stock calculated in accordance with the requirements of Rule 13d-3 under the Act.

Jason Taubman Kalisman, who is the managing member of the InvestCo, may be deemed to beneficially own 7,620,570 shares of Common Stock, which represents approximately 15.61% of the outstanding Common Stock calculated in accordance with the requirements of Rule 13d-3 under the Act.

By virtue of the relationship described herein, the Reporting Persons may be deemed to constitute a “group” for purposes of Section 13(d)(3) of the Act. As a member of a group, each Reporting Person may be deemed to share voting and dispositive power with respect to, and therefore beneficially own, the shares beneficially owned by members of the group as a whole. The filing of this Statement shall not be construed as an admission that a Reporting Person beneficially owns those shares held by any other

10

member of the group. In addition, each Reporting Person expressly disclaims beneficial ownership of any securities reported herein except to the extent such Reporting Person actually exercises voting or dispositive power with respect to such securities.

(b) The number of shares of Common Stock as to which each of the Reporting Persons has sole or shared power to vote, direct the vote, dispose or direct the disposition are as set forth in rows seven through ten of the cover pages hereof. The information set forth in Item 2 is hereby incorporated by reference into this Item 5(b).

The Bylaw Requirements set forth the information required to nominate someone for election to the Board. Any stockholder desiring to nominate any person for election as a director of the Company is required to set forth the name, age, business address and residence address of each nominee, the principal occupation or employment of each nominee; the number of shares of stock of the Company which are owned of record and beneficially by such nominee, if any; and such other information concerning each such nominee as would be required to be disclosed in a proxy statement soliciting proxies for the election of such nominee as a director in an election contest (even if an election contest is not involved) or that is otherwise required to be disclosed, under Section 14(a) of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder. The proposed nominee must also give his written consent

to be named in a proxy statement as a nominee and to serve as a director if elected. The Bylaw Requirements also set forth the information about the proposing stockholder, here the Talisman Fund, and the beneficial owner on whose behalf the nomination is being made to be included in this Notice.

According to the Bylaw Requirements, for a notice to be considered timely for the Annual Meeting, a stockholder’s written notice must be delivered to the Secretary of the Company at the principal executive offices of the Company not less than 90 days nor more than 120 days prior to the first anniversary of the previous year’s annual meeting. The Company disclosed in the 2013 Proxy Statement that February 21, 2014 is the deadline for such notice. This Notice sets forth the information required to nominate a director for election at the Annual Meeting of the stockholders.

The Talisman Fund hereby represents that it is a holder of record of shares of Common Stock on the books and records of the Company and the Talisman Fund intends to appear in person or by proxy at the Annual Meeting to nominate the persons listed below as directors of the Company for election by the holders of common stock of the Company (each, a “Nominee” and together, the “Nominees”), if the Company does not include the Nominees in the Company’s slate of nominees:

Jason Taubman Kalisman

William David Lancaster

Pursuant to the Bylaw Requirements, certain information about each Nominee and about the stockholder giving this Notice is set forth in Annex A. In addition, each Nominee has consented to being named as a nominee on a proxy statement and to serve as a director of the Company, if elected. The written consent of each Nominee is attached as Annex B. The Annexes and all attachments thereto are hereby incorporated into and made a part of this Notice. Accordingly, all matters disclosed in any part of this Notice, including the Annexes and all attachments thereto, should be deemed disclosed for all purposes of this Notice.

The principal address of Talisman, and each of its affiliates, is 324 Royal Palm Way, Suite 229, Palm Beach, FL 33480. With respect to the election by the stockholders, Talisman intends to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Company’s outstanding capital stock required to elect the Nominees and/or otherwise solicit proxies from stockholders of the Company in support of the Nominees. Talisman’s record and beneficial ownership of the Company’s securities as of the date of this Notice is set forth in Annex A. Talisman will notify the Company in writing of the class and number of the Company’s securities owned of record and beneficially as of the record date promptly following the later of the record date or the date the Company publicly discloses the record date.

Other than the relationships between the Nominees and Talisman as disclosed in Annex A, none of Talisman or its affiliates or associates have entered into any agreement, arrangement or understanding with respect to any nomination which is the subject of this Notice. There is no proxy, contract, arrangement, understanding or relationship pursuant to which Talisman or any of its affiliates or associates have a right to vote or have granted a right to vote any shares of any

security of the Company. Other than the Options and Convertible Notes, each as defined and described in Annex A, none of Talisman or its affiliates or associates are parties to any agreements, arrangements or understandings which have the effect or intent to mitigate loss to, manage risk or benefit from share price changes, or increase or decrease the voting power of Talisman with respect to securities of the Company. Talisman will notify the Company in writing of any updates to the information in this paragraph in effect as of the record date promptly following the later of the record date or the date the Company publicly discloses the record date.

In the event that Talisman nominates the Nominees and, for any reason, any Nominee is unable to stand for election at the Annual Meeting, Talisman, in person or by proxy, intends to nominate a person in the place of such Nominee (an “Alternate Nomination”). If, for any reason, more than two director positions are proposed to be filled at the Annual Meeting, Talisman intends to nominate additional persons (each, an “Additional Nominee”) such that Talisman will nominate the Nominees plus a slate of persons sufficient to fill such additional director positions. In either event, Talisman, at the earliest practicable time, will give notice to the Company of any Alternate Nomination or Additional Nominee.

Talisman hereby provides notice of intent to submit a proposal to the Company’s stockholders authorizing reimbursement of all expenses associated with Talisman’s nomination of the Nominees and associated solicitation. The text of the proposal that Talisman intends to submit is as follows:

“RESOLVED, that the Company is directed to pay all expenses incurred by Talisman Realty Capital Master, L.P. or Talisman Group Investments, L.L.C., and any of their affiliates, associated with the nomination of candidates to the Board of Directors by Talisman Realty Capital Master, L.P. and Talisman Group Investments, L.L.C. and the associated solicitation.”

The reason for presenting the proposal is because we believe this nomination and solicitation will increase the value of the Company and the costs should be recovered to support this nomination and solicitation. Talisman has an interest in the proposal insofar as it will cover the expenses Talisman will incur to nominate the Nominees and solicit proxies. Talisman is unable to provide an estimate of such expenses at this time, but will do so upon filing a definitive proxy statement with the Securities and Exchange Commission.

Please advise us immediately if the Company contends that this Notice is deficient in any way or any additional information is required so that we may promptly cure any deficiency.

We look forward to continuing our conversation as you consider including the Nominees in the Company’s slate of nominees.
