                             RULE 12b-25 (b) and (c)

                                    NARRATIVE

      State below in reasonable detail the reasons why Form 10-K, 11-K, 20-F,
10-Q, N-SAR or the transition report portion thereof could not be filed within
the prescribed time period.

      The Company's Quarterly Report on Form 10-QSB for the quarterly period
ended March 31, 2007 cannot be filed within the prescribed time period because
the Company requires additional time for compilation and review to insure
adequate disclosure of certain information required to be included in the Form
10-QSB. The Company's Quarterly Report on Form 10-QSB will be filed on or before
the 5th calendar day following the prescribed due date.

                                     PART IV
                                OTHER INFORMATION

(1)   Name and telephone number of person to contact in regard to this
      notification:

      Qiong (Laby) Wu, Chief Financial Officer, 011 86-10-84927035-108

(2)   Have all other periodic reports required under Section 13 or 15(d) of the
      Securities Exchange Act of 1934 or Section 30 of the Investment Company
      Act of 1940 during the preceding 12 months or for such shorter period that
      the registrant was required to file such report(s) been filed? If the
      answer is no, identify report(s)

                                                                  [X] Yes [ ] No

(3)   Is it anticipated that any significant change in results of operations
      from the corresponding period for the last fiscal year will be reflected
      by the earnings statements to be included in the subject report or portion
      thereof?

                                                                  [X] Yes [ ] No

      If so, attach an explanation of the anticipated change, both narratively
      and quantitatively, and, if appropriate, state the reason why a reasonable
      estimate of the results cannot be made.

      Prior to June 2, 2006, the registrant was a shell corporation known as
      Franklyn Resources III, Inc., which was not engaged in any active
      business. On June 2, 2006, the registrant acquired Sinoenergy Holding
      Limited, a British Virgin Islands corporation ("Sinoenergy"), in a
      transaction which is accounted for as a reverse acquisition. Sinoenergy is
      the sole stockholder of Qingdau Sinogas General Machinery Corporation, a
      Chinese corporation ("Sinogas"). As a result, the results of operations
      for periods prior to June 2, 2006, will be the results of operations of
      Sinogas, which is the accounting acquirer.
