    power infrastructure&#160;&#151; from generation to delivery to
    end use. We are a leader in renewable energy, providing proven,
    megawatt-scale wind turbine designs and electrical control
    systems. We also offer a host of Smart Grid infrastructure
    technologies for power grid operators that enhance the
    reliability, efficiency and capacity of the grid, and integrate
    renewable energy sources into the power infrastructure. These
    include superconductor power cable systems, grid-level surge

    Our company markets two primary, proprietary technologies:
    programmable power electronic converters and high temperature
    superconductor (HTS) wires. The programmability and scalability
    of our power electronic converters differentiates them from most
    competitive offerings. Our HTS wires carry more than 100 times
    the electrical current of comparably sized copper wire. The two
    primary markets we serve are the wind energy market and the
    power transmission and distribution&#160;&#151; or &#147;power

    purposes unless otherwise indicated in the applicable prospectus

    Section&#160;145 of the General Corporation Law of the State of

    in related capacities against amounts paid and expenses incurred
    in connection with an action or proceeding to which he is or is

    reasonably believed to be in or not opposed to the best

    was unlawful; provided that, in the case of actions brought by
    or in the right of the corporation, no indemnification shall be
    made with respect to any matter as to which such person shall
    have been adjudged to be liable to the corporation unless and
    only to the extent that the adjudicating court determines that
    such indemnification is proper under the circumstances.

    Article&#160;VI of the registrant&#146;s by-laws provides that a
    director or officer of the registrant (a)&#160;shall be
    indemnified by the registrant against all expenses (including
    attorneys&#146; fees), judgments, fines and amounts paid in
    settlement actually and reasonably incurred in connection with
    any litigation or other legal proceeding (other than an action
    by or in the right of the registrant) brought against him by
    virtue of his position as a director or officer of the
    registrant if he acted in good faith and in a manner he

    incurred in connection with the defense or settlement of any
    action or suit by or in the right of the registrant by virtue of
    his position as a director or officer of the registrant if he

    in or not opposed to the best interests of the registrant,
    except that no indemnification shall be made with respect to any
    such matter as to which such director or officer shall have been
    adjudged to be liable to the registrant, unless and only to the
    extent that a court determines upon application that, despite
    the adjudication of liability but in view of all the
    circumstances of the case, such person is fairly and reasonably
    entitled to indemnity for such expenses as the court deems
    proper. Notwithstanding the foregoing, to the extent that a
    director or officer has been successful, on the merits or
    otherwise, he shall be indemnified against expenses (including
    attorneys&#146; fees) actually and reasonably incurred by him in
    connection therewith. Expenses incurred in defending a civil or
    criminal action, suit or proceeding may be paid by the
    registrant upon receipt of an undertaking by the director or
    officer to repay such amount if the registrant ultimately
    determines that he is not entitled to indemnification.

the Securities Act of 1933, as amended (the &#147;Securities Act&#148;), for the registration of the

be issued and sold in compliance with applicable federal and state securities laws and in the

such authorization, approval, consent, action, notice or filing is required, it will have been duly
obtained, taken, given or made and will be in full force and effect. We have also assumed that the
delivery by the Company of the Common Stock does not and will not violate, conflict with or
constitute a default under (i)&nbsp;any agreement or instrument to which the Company or any of its
properties is subject, (ii)&nbsp;any law, rule or regulation to which the Company or any of its
properties is subject or (iii)&nbsp;any judicial or regulatory order or decree of any governmental

the time of the issuance and sale of the Common Stock, the Board of Directors of the Company (or
any committee thereof acting pursuant to authority properly delegated to such committee by the
Board of Directors) shall not have taken any action to rescind or otherwise reduce its prior
authorization of the issuance of the Common Stock.

authorized for issuance by proper action of the Company&#146;s Board of Directors or an authorized
committee thereof (the &#147;Authorizing Resolutions&#148;), (ii)&nbsp;the terms of the issuance and sale of the
Common Stock have been duly established in conformity with the Certificate of Incorporation,
By-laws and Authorizing Resolutions, (iii)&nbsp;the shares of Common Stock have been issued and sold as
contemplated by the Registration Statement, the Prospectus and the applicable
supplements to such Prospectus and (iv)&nbsp;the Company has received
the consideration provided for in the Authorizing Resolutions and such consideration per share is not less than the par value per
share of Common Stock, the Common Stock will be validly issued, fully paid and nonassessable.
