The Company is a Delaware corporation. Reference is made to Section 145(a) of the Delaware General Corporation Law (the “DGCL”), which enables a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

In addition, under Section 145(b) of the DGCL, a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine 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 which the Court of Chancery or such other court shall deem proper.

Section 145 further provides that a Delaware corporation is required to indemnify a present or former director or officer against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection with any action, suit or proceeding or in defense of any claim, issue or matter therein as to which such person has been successful on the merits or otherwise; that indemnification provided for by Section 145 shall not be deemed exclusive of any other rights to which the indemnified party may be entitled; and that indemnification provided for by Section 145 shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of such person’s heirs, executors and administrators. Unless ordered by a court, a Delaware corporation may provide indemnification only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in Sections 145(a) and 145(b) of the DGCL. Such determination is to be made (i) by the board of directors by a majority vote of directors who are not parties to such action, suit or proceeding, (ii) by a committee of such directors designated by majority vote of such directors, (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the stockholders.

Section 102(b)(7) of the DGCL provides that the charter of a Delaware corporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of a director’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional

3

misconduct or a knowing violation of the law, (iii) under Section 174 of the DGCL, which provision imposes liability on directors for unlawful payments of dividends, or (iv) for any transaction from which the director derived an improper personal benefit. The Company’s Restated Certificate of Incorporation, as amended, contains a provision permitted by Section 102(b)(7) of the DGCL that generally eliminates the personal liability of each director to the Company and its stockholders for monetary damages for breach of fiduciary duty, unless the director breached his or her duty of loyalty, failed to act in good faith, engaged in intentional misconduct or a knowing violation of law, paid a dividend or approved a stock repurchase in violation of the DGCL or for engaging in a transaction in which the director derived an improper personal benefit. Such provision does not alter a director’s liability under the federal securities laws. In addition, such provision does not affect the availability of equitable remedies, such as an injunction or rescission, for breach of fiduciary duty.

The By-laws of the Company provide that directors and officers of the Company shall be indemnified by the Company to the fullest extent authorized by Delaware law as in effect on the date such By-laws were adopted or as thereafter amended against all expenses, liabilities and losses reasonably incurred in connection with service for or on behalf of the Company. In general, such indemnification shall continue as to any person who has ceased to be a director or officer of the Company and shall inure to the benefit of such person’s heirs, executors and administrators. The By-laws also provide that the right of directors and officers to indemnification shall be a contract right and shall include the right to advancement of expenses prior to the final disposition of a proceeding; provided, however, that such advancement may only be made upon delivery to the Company of an undertaking by such director or officer to repay all amounts so advanced if it shall be determined by a final judicial decision from which there is no right to appeal that such person is not entitled to indemnification.

Not Applicable.

The following exhibits are filed herewith or incorporated herein by reference.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

5

(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.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant 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 Registrant 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 Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

We have acted as counsel for Vicor Corporation, a Delaware corporation (the “Company”), in connection with the preparation of a Registration Statement on Form S-8 (the “Registration Statement”) filed by the Company with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of 6,000,000 shares of common stock, par value $0.01 per share, of the Company (the “Shares”) that may be issued pursuant to the Vicor Corporation Amended and Restated 2000 Stock Option and Incentive Plan, as amended and restated (the “Plan”).

In connection with our representation, we have examined: (i) the Plan; (ii) the Registration Statement; (iii) the Restated Certificate of Incorporation of the Company, as amended; (iv) the Bylaws of the Company, as amended; (v) resolutions of the Board of Directors of the Company relating to the Plan and the issuance of the Shares thereunder; and (vi) such other documents, certificates, and records as we have deemed necessary to enable us to render this opinion. In our examination of the above-referenced documents, we have assumed the genuineness of all signatures, the authenticity of all documents, certificates, and instruments submitted to us as originals and the conformity with the originals of all documents, certificates and instruments submitted to us as copies.

We express no opinion herein as to the laws of any state or jurisdiction other than the General Corporation Law of the State of Delaware and the federal laws of the United States of America. This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or the prospectus that forms a part thereof, other than as expressly stated herein with respect to the issuance of the Shares.

Based upon and subject to the foregoing, we are of the opinion that the Shares covered by the Registration Statement, when issued and paid for pursuant to the terms and conditions of the Plan, and as contemplated by the Registration Statement, will be validly issued, fully paid and nonassessable.
