                  CORPORATE PROPERTY ASSOCIATES 14 INCORPORATED

                  CERTIFICATIONS OF CO-CHIEF EXECUTIVE OFFICERS
                           PURSUANT TO RULE 15d-14(a)

We, William Polk Carey and Gordon F. DuGan, certify that:

1. We have reviewed this Annual Report on Form 10-K of Corporate Property
Associates 14 Incorporated (the "Registrant");

2. Based on our knowledge, this annual 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 annual
report;

3. Based on our knowledge, the financial statements, and other financial
information included in this annual 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 annual report;

4. The Registrant's other certifying officer and we 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 15(d)-15(f)) for the
Registrant and we 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 annual 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 Registrant's disclosure
                  controls and procedures and presented in this annual report
                  our conclusions about the effectiveness of the disclosure
                  controls and procedures, as of the end of the period covered
                  by this annual report based on such evaluation; and

         d)       disclosed in this annual report any change in the Registrant's
                  internal control over financial reporting that occurred during
                  the Registrant's fourth fiscal quarter 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 and we 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 controls 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 controls over financial reporting.
