The following risk factors, together with the factors set forth under the heading "Future Operating Results" included as part of APPENDIX A to the Form 10-K, should be considered carefully in addition to the other information included or incorporated by reference in this Prospectus before purchasing the Shares offered hereby. POSSIBLE VOLATILITY OF SHARE PRICE Investors should be aware that market prices for securities of companies such as ASC are highly volatile. Factors such as fluctuations in the Company's operating results, announcements of technological innovations or new commercial products by the Company or its competitors, governmental regulation, developments in patent or other proprietary rights, and general market conditions may have a significant effect on the market price of the Company's Common Stock. NO DIVIDENDS ANTICIPATED IN FUTURE The Company has not paid any cash dividends on the Common Stock since its inception and does not anticipate paying any cash dividends on its Common Stock in the future. USE OF PROCEEDS The Company will not receive any proceeds from the sale of the Shares by the Selling Stockholder, or by his pledgees, donees, transferees or other successors in interest.

-7- 10 PLAN OF DISTRIBUTION The Shares may be offered and sold from time to time by the Selling Stockholder, or by his pledgees, donees, transferees or other successors in interest. The Selling Stockholder will act independently of the Company in making decisions with respect to the timing, manner and size of each sale. Such sales may be made in the over-the-counter market or otherwise, at prices related to the then current market price or in negotiated transactions, including pursuant to one or more of the following methods: (a) purchases by a broker-dealer as principal and resale by such broker or dealer for its account pursuant to this Prospectus; (b) ordinary brokerage transactions and transactions in which the broker solicits purchasers; and (c) block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction. The Company has been advised by the Selling Stockholder that he has not made any arrangements relating to the distribution of the shares covered by this Prospectus. In effecting sales, broker-dealers engaged by the Selling Stockholder, or by his pledgees, donees, transferees or other successors in interest, may arrange for other broker-dealers to participate. Broker-dealers will receive commissions or discounts from the Selling Stockholder, or his pledgees, donees, transferees or other successors in interest, in amounts to be negotiated immediately prior to the sale. In offering the Shares, the Selling Stockholder and any broker-dealers and any other participating broker-dealers who execute sales for the Selling Stockholder may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales, and any profits realized by the Selling Stockholder and the compensation of such broker-dealer may be deemed to be underwriting discounts and commissions. In addition, any of the Shares which qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this Prospectus. None of the Shares presently qualify for sale pursuant to Rule 144. The Company has advised the Selling Stockholder that during such time as he may be engaged in a distribution of Common Stock included herein he is required to comply with the Securities Act, any rule or regulation under the Securities Act, and Rule 10b-6 under the Exchange Act. The Company has agreed to indemnify the Selling Stockholder against certain liabilities set forth in Section 4.3(e) of the Merger Agreement in connection with the offer and sale of the Shares, including liabilities under the Securities Act. The Selling Stockholder has agreed to indemnify in certain circumstances the Company and certain related persons against certain liabilities set forth in Section 4.3(d)(ii)(A) of the Merger Agreement, including liabilities under the Securities Act. The Company has agreed with the Selling Stockholder to keep the Registration Statement of which this Prospectus is a part effective until the earlier of (i) one month after the date on which such Registration Statement is declared effective, or (ii) the date on which all shares offered hereby have been sold by the Selling Stockholder. The Company intends to de-register any of the Shares not sold by the Selling Stockholder at the end of such period. The Company may, under specified circumstances set forth in Section 4.3(b) of the Merger Agreement, suspend the Registration Statement of which this Prospectus is a part after effectiveness and require that the Selling Stockholder immediately cease sales of shares pursuant to such Registration Statement.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct 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 V of the Registrant's By-laws provides that a director or officer of the Registrant (a) shall be indemnified by the Registrant against all expenses (including attorneys' 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 reasonably believed to be in or not opposed to the best interests of the Registrant, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful and (b) shall be indemnified by the Registrant against expenses (including attorneys' fees) 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 acted in good faith and in a manner he reasonably believed to be 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 II-1 13 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' 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. Indemnification shall be made by the Registrant upon a determination that the applicable standard of conduct required for indemnification has been met and that indemnification of a director or officer is proper. Such determination shall be made (a) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to the action, or (b) if such a quorum is not obtainable, or if a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (c) by the stockholders of the Registrant. Article V of the By-laws of the Registrant further provides that the indemnification provided therein is not exclusive, and provides that to the extent the Delaware General Corporation Law is amended or supplemented, Article V shall be amended automatically and construed so as to permit indemnification and advancement of expenses to the fullest extent permitted by such law. Article EIGHTH of the Registrant's Certificate of Incorporation provides that no director of the Registrant shall be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director; provided, that a director shall remain liable (i) for any breach of such director's duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for participation in a Board of Directors' action authorizing an unlawful dividend or unlawful stock purchase or redemption under Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which such director derived an improper personal benefit.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The Company hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Corporation pursuant to the indemnification provisions described herein, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

   10

jurisdiction in which the nature of its businesses or the ownership or leasing
of its properties requires such qualification, except where the failure to be so

     2B.3 AUTHORITY AND NONCONTRAVENTION.

Stockholder and, if requested by ASC, the Stockholder shall immediately cease
making offers or sales of shares under the Stockholder Registration Statement

          (d) ASC and the Stockholder shall cooperate in the preparation of all
tax returns and audits for any tax periods for which one party could reasonably
require the assistance of the other party in obtaining the necessary
information.

     4.5 RESTRICTION ON TRANSFER. The Stockholder will not sell, exchange,
transfer, pledge, dispose or otherwise reduce his risk relative to any ASC
Shares or any part thereof owned by him until such time after the Effective Time
as financial results covering at least thirty (30) days of the combined
operations of ASC and AET after the Closing have been filed by ASC with the
Securities and Exchange Commission or published by ASC in an Annual Report on
Form 10-K, a Quarterly Report on Form 10-Q, a Current Report on Form 8-K, a
quarterly or monthly earnings release, a press release, a registration
statement, or other public issuance which includes combined sales and income of
ASC and AET (the "Financial Results").

     4.6 PAYMENT OF OUTSTANDING DEBT AND RELEASE OF GUARANTEES. Within 10
business days of the Closing, ASC shall pay and terminate, on behalf of AET,
AET's current line of credit with Eastern Bank in the amount of $50,000, AET's
current working capital loan with Eastern Bank in the amount of $19,166.67, and
AET's line of credit with American Express Small Business Service in the amount
of $10,000. ASC and the Stockholder agree to work together with Eastern Bank and
American Express Small Business Service to cancel the promissory notes and other
debt documents and release the guarantees made by the Stockholder.

     4.7 PUBLICATION OF FINANCIAL RESULTS. ASC agrees to use its best efforts
to publish Financial Results by September 30, 1997.

     4.8 PAYMENT OF TAX OBLIGATIONS. Within 5 business days after the Closing,
ASC will cooperate with the Stockholder to cause AET to use the proceeds
received by AET pursuant to Sections 1.3(e) and (g) to pay up to $91,092 of
federal and state payroll taxes due from AET prior to the date of the Closing
and up to $5,682 to pay AET's accounting fees and 1997 Massachusetts corporate
excise taxes. Subject to such payments, the Stockholder agrees to pay all Taxes
owed by AET with respect to periods prior to the Closing in excess of any
accruals or reserves (excluding any reserves, accruals or tax assets) for taxes
reflected on the AET 1997 Balance Sheet.

     4.9 ESCROW. Upon the Closing, ASC will hold and not transfer to the
Stockholder 6,831 ASC Shares. As promptly as possible after the Closing Date,
ASC shall deposit with the Escrow Agent such ASC Shares issuable to the
Stockholder pursuant to Section 1.5 (the "Escrow Fund"), for the purpose of
securing the indemnification obligations of the Stockholder as set forth in this
Agreement. The Escrow Fund shall be held by the Escrow Agent under the Escrow
Agreement pursuant to the terms thereof. The Parties agree to execute an Escrow
Agreement substantially in the form attached hereto as EXHIBIT F with such
changes as the 


                                       18
   23

contracting parties may agree upon. The Escrow Fund shall be held as a trust
fund and shall not be subject to any lien, attachment, trustee process or any
other judicial process of any creditor of any party, and shall be held and
disbursed solely for the purposes and in accordance with the terms of the Escrow
Agreement.

     4.10 RELEASE OF LEASE GUARANTEE. ASC agrees to use its best efforts to
obtain the release of the Stockholder from the Stockholder's guaranty of the
lease dated December 29, 1992 of the premises at 155-B New Boston Street,
Woburn, MA as promptly as practical after the Closing Date. For so long as ASC
is unable to obtain such release, ASC agrees that it will not extend such lease
without the Stockholder's consent and it will reimburse the Stockholder for any
costs or expenses incurred by the Stockholder with respect to such guarantee for
any periods following the Closing Date, subject to the Stockholder's
indemnification obligations as set forth in Article VI.

                                 INDEMNIFICATION

     6.1 INDEMNIFICATION BY THE STOCKHOLDER. The Stockholder shall indemnify ASC
in respect of, and hold ASC harmless against, any and all debts, obligations and
other liabilities, monetary damages, fines, fees, penalties, interest
obligations, deficiencies, losses and expenses (including without limitation
amounts paid in settlement, interest, court costs, costs of investigations, fees
and expenses of attorneys, accountants, financial advisors and other experts,
and other expenses of litigation) ("Damages") incurred or suffered by ASC or any
officer or director thereof resulting from, relating to or constituting:

          (a) any misrepresentation, breach of warranty or failure to perform
any covenant or agreement of AET or the Stockholder contained in this Agreement;



                                       20
   25

          (b) any failure of the Stockholder to have good, valid and marketable
title to the issued and outstanding AET Shares held by the Stockholder, free and
clear of all liens, claims, pledges, options, adverse claims or charges of any
nature whatsoever;

          (c) all liabilities resulting from any claim by a stockholder or
former stockholder of AET or any other person, firm, corporation or entity,
seeking to assert, or based upon: (i) ownership or rights to ownership of any
share of stock interests of AET; (ii) any rights of a stockholder, including any
option or preemptive rights or rights to notice or to vote, but excluding
dissenter's rights; (iii) any rights under the Articles of Organization,
By-laws, or other organizational document of AET; or (iv) any claim that his,
her or its shares were wrongly repurchased by AET; or

          (d) all liabilities resulting from the failure of the Stockholder to
have any back wages owed to any AET employees at the date of Closing paid in
full as of the date of Closing or to have the taxes and expenses described in
Section 4.8 hereof.


     6.2 INDEMNIFICATION BY ASC. ASC shall indemnify the Stockholder in respect
of, and hold it harmless against, any and all Damages incurred or suffered by
the Stockholder or any officer or director of AET resulting from, relating to or
constituting any misrepresentation, breach of warranty or failure to perform any
covenant or agreement of ASC contained in this Agreement.

     6.3 CLAIMS FOR INDEMNIFICATION.

          (a) A Party entitled to indemnification under this Article VI (an
"Indemnified Party") shall give prompt written notification to the party from
which indemnification is sought (the "Indemnifying Party") of the commencement
of any action, suit or proceeding relating to a third party claim for which
indemnification pursuant to this Article VI may be sought. Within 15 days after
delivery of such notification, the Indemnifying Party may, upon written notice
thereof to the Indemnified Party, assume control of the defense of such action,
suit or proceeding with counsel reasonably satisfactory to the Indemnified
Party, provided the Indemnifying Party acknowledges in writing to the
Indemnified Party that any damages, fines, costs or other liabilities that may
be assessed against the Indemnified Party in connection with such action, suit
or proceeding constitute Damages for which the Indemnified Party shall be
entitled to indemnification pursuant to this Article VI. If the Indemnifying
Party does not assume control of such defense, the Indemnified Party shall
control such defense. The party not controlling such defense may participate
therein at its own expense; provided that if the Indemnifying Party assumes
control of such defense and the Indemnified Party reasonably concludes that the
Indemnifying Party and the Indemnified Party have conflicting interests or


                                       21
   26

different defenses available with respect to such action, suit or proceeding,
the reasonable fees and expenses of counsel to the Indemnified Party shall be
considered "Damages" for purposes of this Agreement. The party controlling such
defense shall keep the other party advised of the status of such action, suit or
proceeding and the defense thereof and shall consider in good faith
recommendations made by the other party with respect thereto. The Indemnified
Party shall not agree to any settlement of such action, suit or proceeding
without the prior written consent of the Indemnifying Party, which shall not be
unreasonably withheld. The Indemnifying Party shall not agree to any settlement
of such action, suit or proceeding without the prior written consent of the
Indemnified Party, which shall not be unreasonably withheld.

          (b) Notwithstanding the provisions of Section 6.3(a), if a third party
asserts (other than by means of a lawsuit) that ASC is liable to it for a
monetary or other obligation which may constitute or result in Damages for which
ASC may be entitled to indemnification pursuant to this Article VI, and ASC
reasonably determines that it has a valid business reason to fulfill such
obligation, then (i) if time is of the essence, ASC shall be entitled to satisfy
such obligation, without prior notice to or consent from the Stockholder
(however ASC shall use its reasonable best efforts to give notice to and consult
with the Stockholder prior to acting on the obligation, whenever practicable),
(ii) ASC may make a claim for indemnification pursuant to this Article VI in
accordance with the provisions of this Section 6.3, and (iii) ASC shall be
reimbursed, in accordance with the provisions of this Section 6.3, for any such
Damages for which it is entitled to indemnification pursuant to this Article VI
(subject to the right of the Stockholder to dispute ASC's entitlement to
indemnification or the amount for which it is entitled to indemnification).

          (c) Promptly following delivery of a written notice from the
Indemnified Party which contains (i) a description of any Damages incurred by
the Indemnified Party, (ii) a statement that the Indemnified Party is entitled
to indemnification under this Article VI for such Damages and a reasonable
explanation of the basis therefor, and (iii) a demand for payment in the amount
of such Damages, the Indemnifying Party shall pay such amount to the Indemnified
Party, by check or by wire transfer.

     6.4 SURVIVAL. The representations and warranties of AET and the Stockholder
set forth in this Agreement shall survive the Closing and the consummation of
the transactions contemplated hereby and continue until 365 days after the
Closing and shall not be affected by any examination made for or on behalf of
ASC or the knowledge of any of ASC's officers, directors, stockholders,
employees or agents. Notwithstanding the foregoing, the representations and
warranties contained in Section 2B.14 relating to compliance with legal matters
and 2B.15 relating to tax matters shall survive the Closing and the consummation
of the



                                       22
   27

transactions contemplated thereby and continue until the expiration of the
applicable statute of limitations.

     6.5 LIMITATIONS. Notwithstanding anything to the contrary herein, the
aggregate liability for Damages under this Article VI shall not exceed the
Escrow Fund.

Ladies and Gentlemen:

       We have assisted in the preparation of the Registration Statement on Form
S-3 (the "Registration Statement") filed with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, relating to the
registration of 68,306 shares of common stock, $.01 par value per share (the
"Shares"), of American Superconductor Corporation, a Delaware corporation (the
"Company"), held by a certain stockholder of the Company.

       We have examined the Certificate of Incorporation and By-laws of the
Company and all amendments thereto and have examined and relied on the
originals, or copies certified to our satisfaction, of such records of meetings,
written actions in lieu of meetings, or resolutions adopted at meetings, of the
directors of the Company and such other documents and instruments as in our
judgment are necessary or appropriate to enable us to render the opinions
expressed below.

       In our examination of the foregoing documents, we have assumed (i) the
genuineness of all signatures and the authenticity of all documents submitted to
us as originals, (ii) the conformity to the originals of all documents submitted
to us as certified or photostatic copies, and (iii) the authenticity of the
originals of the latter documents.

       Based upon and subject to the foregoing, we are of the opinion that the
Shares have been duly and validly authorized and issued and are fully paid and
non-assessable.

       We hereby consent to the use of our name in the Registration Statement
and in the related Prospectus under the caption "Legal Matters" and to the
filing of this opinion as an exhibit to the Registration Statement.


                                             Very truly yours,
