| 1. | I    have reviewed this annual report on Form 10-K of UQM Technologies, Inc.:2.
Based    on my knowledge, this annual report does not contain any untrue statement of 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 my 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 officers 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)) 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.
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; andc.
Disclosed    in this annual 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; and5.
The    registrant’s other certifying officers 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;    andb.
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.Date:  June 6, 2006/s/  William G.    RankinWilliam G. RankinChairman, President andChief Executive Officer |
