CUSIP No. 40420K103 13D
Page 8  of 11 Pages
 
Item 1.  Security and Issuer.
 
The title of the class of equity securities to which this statement relates is common stock, $0.01 par value (the “Common Stock”), of HKN, Inc. (the “Issuer”), whose principal executive offices are located at 180 State Street, Suite 200, Southlake, TX 76092.
 
Item 2.  Identity and Background.
 
This statement on Schedule 13D (the "Statement") is being jointly filed by each of the following persons (being herein collectively referred to as the "Reporting Persons") pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended (the "Act"), with respect to the Common Stock: Brean Murray Carret Group Inc., a British Virgin Islands company ("Brean"); Lyford Investments Enterprises Ltd., a British Virgin Islands company ("Lyford"); AEF Finance Ltd., a British Virgin Islands company ("AEF");UniPureEnergy Acquisition Ltd., a British Virgin Islands company ("UEA"); Quadrant Management, Inc., a Delaware corporation ("Quadrant"); and Wayne Quasha ("Quasha") as the beneficial owner of the WQ, AQ and JQ Trusts.

The Reporting Persons are making a single joint filing pursuant to Rule 13d-1(k)(1) of the Act.

Previously, Lyford, UEA and Quadrant reported beneficial ownership of 164,391, 62,164 and 36,768 shares of stock, respectively.

The Reporting Persons are filing this Statement because they may be deemed to be a "group" within the meaning of Section 13(d)(3) of the Act, with respect to the transaction described in Item 4 of this Statement. Except as expressly otherwise set forth in this Statement, each Reporting Person disclaims beneficial ownership of the shares of Common Stock beneficially owned by any other Reporting Person or any other person.

On October 9, 2011, Phyllis Quasha ceased to beneficially own all of the shares of Brean as a result of her death.  During her lifetime Mrs. Quasha settled the Everest Trust under which she was the beneficial owner of Brean. Subsequent to her death, Wayne Quasha settled the AQ, JQ and WQ trusts of which he is the beneficial owner and appointed the assets from the Everest Trust to these trusts making him the beneficial owner of Brean. The AQ, JQ and WQ trusts now owns all of the shares of Brean which controls UEA, AEF, Lyford and Quadrant. Vicali Services (BVI) Inc., a British Virgin Islands company ("Vicali"),is the sole director of Brean, and Susan V. Demers, a United States citizen ("Demers"), and Andrea J. Douglas, a citizen of New Zealand ("Douglas"), are the directors of Vicali.

Item 4.  Purpose of Transaction.
 
The Reporting Persons acquired the shares of Common Stock of the Issuer for general investment purposes. The Reporting Persons will continuously evaluate their ownership of Common Stock and the Issuer's business and industry. Depending on market conditions and other factors that the Reporting Persons may deem material to their investment decision, including the availability of other investment opportunities, each Reporting Person may from time to time acquire additional shares of Common Stock that such Reporting Person now owns or may hereafter acquire.

Without limitation of the foregoing (and consistent with their investment purpose), the Reporting Persons will continue to consider alternative courses of action and will in the future take such actions with respect to their investment in the Issuer as they deem appropriate in light of the circumstances existing from time to time. Such actions, in addition to that discussed above, may include making recommendations to members of management concerning various business strategies, acquisitions, policies, seeking to acquire control of the Issuer through a merger, proxy solicitation, tender offer, significant equity investment, exchange offer or otherwise, or such other actions as the Reporting Persons may deem appropriate.

(b) Brean is deemed to have the power to vote or to direct the vote of, and to dispose or direct the disposition of, the Common Stock beneficially owned by UEA, Lyford, AEF and Quadrant. Because of his relationship to Lyford, AEF, UEA & Quadrant as identified in Item 2 above, Quasha shares voting and dispositive power with regard to the Common Stock owned by UEA and Quadrant and, therefore, may be deemed to have indirect beneficial ownership of the Common Stock owned by UEA, Lyford, AEF and Quadrant.
