    Corporation of America Holdings;

2.  Based on my knowledge, this 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 condition, results of operations and cash flows of
    the registrant as of, and for, the periods presented in this report;

4.  The registrant'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 registrant 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 registrant, 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)  Evaluated the effectiveness of the registrant'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

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

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