                                     PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

      The Company's directors and executive officers are indemnified as provided
by the  Delaware  General  Corporation  Law  and  the  Company's  Bylaws.  These
provisions state that the Company's directors may cause the Company to indemnify
a director or former director against all costs, charges and expenses, including
an  amount  paid to  settle  an action  or  satisfy  a  judgment,  actually  and
reasonably  incurred  by him  as a  result  of him  acting  as a  director.  The
indemnification  of costs  can  include  an  amount  paid to settle an action or
satisfy a judgment.  Such  indemnification is at the discretion of the Company's
board of directors and is subject to the  Securities  and Exchange  Commission's
policy regarding indemnification.

      Insofar as  indemnification  for liabilities  arising under the Securities
Act of 1933 may be permitted to directors,  officers or persons  controlling the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised  that in the opinion of the  Securities  and Exchange  Commission,  such
indemnification  is against  public policy as expressed in the Securities Act of
1933 and is, therefore, unenforceable.

ITEM 25. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

      The  following  table  sets  forth  the  costs and  expenses,  other  than
underwriting  discounts  and  commissions,  if any,  payable  by the  Registrant

Pursuant to the terms of the warrant,  each investor has contractually agreed to
restrict  its ability to  exercise  the  warrants  to an amount  which would not

of $3.60 per share.  Pursuant to the terms of the  warrant,  each  investor  has
contractually  agreed to restrict  its ability to  exercise  the  warrants to an
amount  which  would not exceed the  difference  between the number of shares of
common stock  beneficially  owned by the holder or issuable upon exercise of the
warrant held by such holder and 9.9% of the  outstanding  shares of common stock
of the Company.  New York Global  Securities acted as the placement agent of the

has contractually  agreed to restrict its ability to exercise the warrants to an
amount  which  would not exceed the  difference  between the number of shares of
common stock  beneficially  owned by the holder or issuable upon exercise of the
warrant held by such holder and 9.9% of the  outstanding  shares of common stock

      * All of the above  offerings  and sales  were  deemed to be exempt  under
Section  4(2) of the  Securities  Act of 1933,  as amended.  No  advertising  or
general solicitation was employed in offering the securities.  The offerings and
sales  were made to a limited  number of  persons,  all of whom were  accredited
investors,  business  associates  of our  company or  executive  officers of our
company,  and  transfer was  restricted  by our company in  accordance  with the
requirements  of the Securities Act of 1933. In addition to  representations  by
the above-referenced  persons, we have made independent  determinations that all
of the above-referenced  persons were accredited or sophisticated investors, and
that they were  capable of analyzing  the merits and risks of their  investment,
and  that  they   understood  the  speculative   nature  of  their   investment.
Furthermore,  all of the  above-referenced  persons were provided with access to
our Securities and Exchange Commission filings.

      Pursuant to a Share Purchase Agreement,  which closed on December 6, 2005,
we issued an aggregate  4,000,000 shares of common stock to former  shareholders
of Xian Xilan  Natural Gas Co.,  Ltd.  These shares were issued in reliance upon
the exemption  from  registration  provided by Regulation S under the Securities
Act of 1933, as amended

      Except as expressly set forth above,  the individuals and entities to whom
we issued securities as indicated in this section of the registration  statement
are unaffiliated with us.

ITEM 28. UNDERTAKINGS.

The undersigned Company hereby undertakes to:

(1) File,  during  any  period  in which  offers  or sales  are  being  made,  a
post-effective amendment to this registration statement to:

(i) Include any prospectus required by Section 10(a)(3) of the Securities Act of
1933, as amended (the "Securities Act");

(ii)  Reflect  in the  prospectus  any facts or events  which,  individually  or
together,  represent a fundamental change in the information in the registration
statement.  Notwithstanding the foregoing, any increase or decrease in volume of
securities  offered (if the total dollar value of the  securities  offered would
not exceed that which was registered) and any deviation from the low or high end
of the  estimated  maximum  offering  range  may be  reflected  in the  form  of
prospectus  filed  with  the  Commission  pursuant  to  Rule  424(b)  under  the
Securities Act if, in the aggregate,  the changes in volume and price  represent
no more than a 20% change in the maximum  aggregate  offering price set forth in
the  "Calculation  of  Registration  Fee"  table in the  effective  registration
statement, and

(iii) Include any  additional  or changed  material  information  on the plan of
distribution.

(2)  For   determining   liability   under  the   Securities   Act,  treat  each
post-effective  amendment  as a new  registration  statement  of the  securities
offered,  and the offering of the securities at that time to be the initial bona
fide offering.

(3) File a  post-effective  amendment  to remove  from  registration  any of the
securities that remain unsold at the end of the offering.

(4) For determining liability of the undersigned small business issuer under the
Securities Act to any purchaser in the initial  distribution  of the securities,
the  undersigned  undertakes  that in a primary  offering of  securities  of the
undersigned  small  business  issuer  pursuant to this  registration  statement,
regardless  of the  underwriting  method  used to  sell  the  securities  to the
purchaser,  if the  securities are offered or sold to such purchaser by means of
any of the following communications,  the undersigned small business issuer will
be a seller  to the  purchaser  and  will be  considered  to offer or sell  such
securities to such purchaser:

(i) Any preliminary  prospectus or prospectus of the undersigned  small business
issuer relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free  writing  prospectus  relating to the  offering  prepared by or on
behalf of the  undersigned  small business  issuer or used or referred to by the
undersigned small business issuer;

(iii) The portion of any other free writing prospectus  relating to the offering
containing  material  information about the undersigned small business issuer or
its  securities  provided  by or on behalf  of the  undersigned  small  business
issuer; and

(iv)  Any  other  communication  that is an offer  in the  offering  made by the
undersigned small business issuer to the purchaser.


                                      II-3


      Insofar as  indemnification  for liabilities  arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised  that in the opinion of the  Securities  and  Exchange  Commission  such
indemnification  is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.

      In the event that a claim for  indemnification  against  such  liabilities
(other  than the  payment  by the  Company  of  expenses  incurred  or paid by a
director, officer or controlling person of the Company in the successful defense
of any action,  suit or  proceeding)  is asserted by such  director,  officer or
controlling  person in connection  with the  securities  being  registered,  the
Company  will,  unless in the opinion of its counsel the matter has been settled
by  controlling  precedent,  submit to a court of appropriate  jurisdiction  the
question  whether  such  indemnification  by  it is  against  public  policy  as
expressed in the Securities  Act and will be governed by the final  adjudication
of such issue.

      Each  prospectus  filed  pursuant to Rule 424(b) as part of a registration
statement relating to an offering, other than registration statements relying on
Rule 430B or other than  prospectuses  filed in reliance on Rule 430A,  shall be
deemed to be part of and included in the  registration  statement as of the date
it is first used after effectiveness.  Provided, however, that no statement made
in a  registration  statement  or  prospectus  that is part of the  registration
statement or made in a document incorporated or deemed incorporated by reference
into the  registration  statement or prospectus that is part of the registration
statement  will, as to a purchaser with a time of contract of sale prior to such
first use,  supersede or modify any statement that was made in the  registration
statement or prospectus that was part of the  registration  statement or made in
any such document immediately prior to such date of first use.


                                      II-4


                                   SIGNATURES

Registrant certifies that it has reasonable grounds to believe that it meets all

statement to be signed on its behalf by the undersigned,  in Xian, China, on May
