     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

________________________________________________________________________________
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: UniPureEnergy

Islands company ("Q Management"), as Trustee of the PQ II Trust, a trust
administered under the laws of the British Virgin Islands ("PQ II") and as
Trustee of the PQ III Trust, a trust administered under the laws of the British
Virgin Islands ("PQ III"); and Phyllis Quasha ("Quasha").

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

     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.

     Q Management, as Trustee of PQ II and as Trustee of PQ III, owns all of the
shares of UEA. Vicali Services (BVI) Inc., a British Virgin Islands company

citizen ("Demers"), and Andrea J. Douglas, a citizen of New Zealand ("Douglas"),
are the directors of Vicali. Q Management is the sole trustee of each of PQ II
and PQ III. Each of PQ II and PQ III are revocable trusts. Vicali is the sole
director of Q Management. Quasha, an Australian citizen, is the settlor of each

     During the past five years, no Reporting Person and, to the knowledge of
the Reporting Persons, none of the executive officers or directors of the
Reporting Persons, if applicable, has been convicted in a criminal proceeding
(excluding traffic violations or similar misdemeanors) or has been a party to a
civil proceeding of a judicial or administrative body of competent jurisdiction
and as a result of such proceeding was or is subject to a judgment, decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

________________________________________________________________________________
Item 3.  Source and Amount of Funds or Other Consideration.

     As described in Item 5(c) below, UEA was issued 750,000 restrcited shares
of Common Stock as part of a Securities Exchange Agreement dated June 30, 2009.

                                     Page 6

________________________________________________________________________________
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.

________________________________________________________________________________
Item 5.  Interest in Securities of the Issuer.

     (a) The Reporting Persons may be deemed to be a group according to the
rules under the Act, and as such a group, may be deemed to beneficially own an
aggregate of 750,000 shares of Common Stock as of April 7, 2010, which was
approx. 7.8% of the outstanding Common Stock on such date (all computations of
the percentage of Common Stock set forth herein are based on a total of
9,596,543 shares of Common Stock outstanding as of November 1, 2009 as reported
in the Issuer's latest 10-Q statement, as filed with the Securities and Exchange
COmmission on November 5, 2009). As of May 13, 2010, each Reporting Person
beneficially owns the following number of shares of Common Stock:

Name of Filing Person                     Shares                   Percent of
                                    Beneficially Owned             Outstanding

UniPureEnergy Acquisition Ltd.            750,000                  7.8%

Q Management Services (PTC) Ltd.,         750,000                  7.8%
as Trustee of the PQ II and
as Trustee of the PQ III Trust

Phyllis Quasha                            750,000                  7.8%

     (b) UEA is deemed to solely 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. Because of their relationship to UEA as identified in Item 2
above, each of Q Management, as Trustee of PQII and as Trustee of PQ III,
Vicali, Demers, Douglas, Q Management and Quasha share voting and dispositive
power with regard to the Common Stock owned by UEA and, therefore, may be deemed
to have indirect beneficial ownership of the Common Stock owned by UEA.

     (c) The following transactions were effective by the identified parties
during the sixty days preceding the date of filing of this Schedule 13d:

Reporting Person    Date     Buy/Sell     Number of Shares      Price Per Share

                                     Page 7

________________________________________________________________________________
Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.

     Alan G. Quasha, the Attorney-in-fact for UAE and the Chairman of the Board
of Directors of the Issuer, has been appointed by the Reporting Persons to
effect the purposes described in Item 4 above. The Reporting Persons may grant
Mr. Quasha proxies to vote the Common Stock held by each Reporting Person in the
event a meeting is held as contemplated in Item 4.

     Except as described herein, none of the Reporting Persons, and none of the
executive officers or directors of the Reporting Persons, has any contracts,
arrangements, understandings or relationships (legal or otherwise) with any
person with respect to any securities of the Issuer, including but not limited
to, transfer or voting of any of the securities of the Issuer, finder's fees,
joint ventures, loan or option arrangements, puts or calls, guarantees of
profits, division of profits or loss, or the giving or withholding of proxies,
or a pledge or contingency the occurence of which would give another person
voting or vestment power over securities of the Issuer.
