    Dear Mr. Spirgel:

    With respect to your letter dated April 25, 2005, and subsequent
    conversations with Mr. Ted Yu, please find the following amended
    responses attached to this letter:

    1.  Certification required by Rule 13a-14(a)

    3.  Disclosure required by Item 307 of Regulation S-K

    4.  Disclosure required by Item 308 of Regulation S-K

    We will submit an amended Form 10-K for the year ending 12-31-05
    and an amended 1st Qt Form 10-Q incorporating these additional
    amended certifications and disclosures.

    We do confirm that all future periodic reports will include these
    certifications and disclosures.  The 2nd Qt Form 10-Q does
    incorporate these amended changes.

    We also acknowledge that:

    The company is resaponsible for the adequacy and accuracy of the
    disclosures in the filings;

    Staff comments or changes to disclosure in response to staff
    comments in the filings reviewed by the staff do not foreclose the
    Commission from taking any action with respect to the filing;

    The company may not assert staff comments as a defense in any
    proceeding initiated by the Commission or any person under the
    federal securities laws of the United States.

    Thank you and your staff for your assistance in clarifying the
    issues that have been addressed in our responses.

    Very truly yours,

    Michel Maes
    Co-General Partner

    Item 9:    Disagreements on Accounting and Financial Disclosure
               Matters

    TASA has no independent accountant at present, in accordance with
    Rule 3-11 of Regulation S-X

    Item 9A    Controls and Procedures

    The Partnership's disclosure controls and procedures are designed
    to ensure that information required to be disclosed in reports
    that are filed or submitted under the Securities Exchange Act of
    1934, as amended, is recorded, processed, summerized and reported
    within the time periods specified in the rules and forms of the
    Securities and Exchange Commission.  Disclosure controls and
    procedures include, without limitation, controls and proceedures
    designed to ensure that information required to be disclosed by an
    issuer in the reports that it files or submits under the Act is
    accumulated and communicated to the issuer's management including
    its principal executive and principal financial officers, or
    persons performing similar functions (the General Partners), as
    appropriate to allow timely decisions regarding required
    disclosure.

    The General Partners have reviewed the effectiveness of the
    Partnership's disclosure controls and procedures as of the end of
    the period covered by this Form 10-K report and have concluded
    that the disclosure controls and procedures are effective.

    There were no changes in our internal control over financial
    reporting during the three months ended December 31, 2004 that
    have materially affected, or are reasonably likely to materially
    affect, our internal control over financial reporting.

    None
