                  CERTIFICATION OF PRINCIPAL EXECUTIVE OFFICER

I, Vahan Kololian, Chief Executive Officer, certify that:

1.  I have reviewed this Quarterly Report on Form 10-QSB of Terra Nova
    Acquisition Corporation;

2.  Based on my knowledge, this quarterly report does not contain any untrue
    statement of a material fact or omit to state a material fact necessary to
    make the statements made, in light of the circumstances under which such
    statements were made, not misleading with respect to the period covered by
    this report;

3.  Based on my knowledge, the financial statements, and other financial
    information included in this report, fairly present in all material respects
    the financial conditions, results of operations and cash flows of the small
    business issuer as of, and for, the periods presented in this report;

4.  The small business issuer's other certifying officer(s) and I are
    responsible for establishing and maintaining disclosure controls and
    procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and
    internal control over financial reporting (as defined in Exchange Act Rules
    13a-15(f) and 15d-15(f)) for the small business issuer and have:

    a)  Designed such disclosure controls and procedures, or caused such
        disclosure controls and procedures to be designed under our supervision,
        to ensure that material information relating to the small business
        issuer, including its consolidated subsidiaries, is made known to us by
        others within those entities, particularly during the period in which
        this report is being prepared;

    b)  Designed such internal control over financial reporting, or caused such
        internal control over financial reporting to be designed under our
        supervision, to provide reasonable assurance regarding the reliability
        of financial reporting and the preparation of financial statements for
        external purposes in accordance with generally accepted accounting
        principles;

     c) Evaluated the effectiveness of the small business issuer's disclosure
        controls and procedures and presented in this report our conclusions
        about the effectiveness of the disclosure controls and procedures, as of
        the end of the period covered by this report based on such evaluation;
        and

     d) Disclosed in this report any change in the small business issuer's
        internal control over financial reporting that occurred during the small
        business issuer's most recent fiscal quarter (the small business
        issuer's fourth fiscal quarter in the case of an annual report) that has
        materially affected, or is reasonably likely to materially affect, the
        small business issuer's internal control over financial reporting; and

5.  The small business issuer's other certifying officer(s) and I have
    disclosed, based on our most recent evaluation of internal control over
    financial reporting, to the small business

    issuer's auditors and the audit committee of the small business issuer's
    board of directors (or persons performing the equivalent functions):

    a)  All significant deficiencies and material weaknesses in the design or
        operation of internal control over financial reporting which are
        reasonably likely to adversely affect the small business issuer's
        ability to record, process, summarize and report financial information;
        and

    b)  Any fraud, whether or not material, that involves management or other
        employees who have a significant role in the small business issuer's
        internal control over financial reporting.
