Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement. Item 4. Description of Securities Not applicable. Item 5. Interests of Named Experts and Counsel Not applicable. Item 6. Indemnification of Directors and Officers Section 145 of the Delaware General Corporation Law grants the Registrant the power to indemnify each 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 by reason of the fact that he is or was a director, officer, employee or agent of the Registrant, or is or was serving at the request of the Registrant as a 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 in connection with such action, suit or proceeding 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; provided, however, no indemnification shall be made in connection with any proceeding brought by or in the right of the Registrant where the person involved is adjudged to be liable to the Registrant except to the extent approved by a court. Article VII of the Registrant's Restated By-laws provides that the Registrant shall indemnify each person (i) who is a present or former director or officer of the Registrant or who at the request of the Registrant serves or has served a partnership or joint venture to which the Registrant is a party, a nominee trust established by the Registrant, or an employee benefit plan sponsored by the Registrant in one of those capacities or as a trustee, partner or fiduciary and (ii) who by reason of his position was, is, or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, against all expenses incurred in connection with the defense or disposition of any such proceeding if the person acted in good faith, and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Registrant. The Registrant may also grant indemnification and the advancement of expenses to any employee or agent of the Registrant or to any officer or director of any other corporation or enterprise who serves or has served as such at the request of the Registrant. The indemnification provided for in Article VII is not exclusive of any other rights to which those seeking indemnification may be entitled. Article VII also provides that the Registrant shall have the power to purchase and maintain insurance on behalf of any officer, director, employee or agent against any liability asserted against and incurred by him in any capacity, or arising out of his status as such, whether or not the Registrant would have the power to indemnify him against such liability under the provisions of Article VII. Article TENTH of the Registrant's Restated Certificate of Incorporation eliminates a director's personal liability for monetary damages to the Registrant and its stockholders for breaches of fiduciary duty as a director, except for breach of the director's duty of loyalty to the Registrant or its stockholders, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, pursuant to Section 174 of the Delaware General Corporation Law, or for any transaction from which the director derived an improper personal benefit. The Registrant maintains directors' and officers' liability insurance. Item 7. Exemption from Registration Claimed Not applicable. Item 8. Exhibits The Exhibit Index immediately preceding the exhibits is incorporated herein by reference. Item 9. Undertakings 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 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. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (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 of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934(and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, 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 of 1933 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 Securities and Exchange 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. SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, hereunto duly authorized, in the Town of Woburn, Commonwealth of Massachusetts on this 8th day of June, 2000.

      Re:     Network Device Inc. 1997 Stock Option Plan
              Network Device Inc. 1999 Stock Option Plan

Ladies and Gentlemen:

                  I have acted as corporate counsel to Alpha Industries,
Inc., a Delaware corporation (the "Registrant"), in connection with the
preparation of a Registration Statement on Form S-8 (the "Registration
Statement"), for the purpose of registering with the Securities and
Exchange Commission (the "Commission"), under the Securities Act of 1933,
as amended (the "Securities Act"), of an aggregate of 178,731 shares of the
Registrant's common stock, par value $0.25 per share ("Common Stock"),
issuable pursuant to the Network Device Inc. 1997 Stock Option Plan and the
Network Device Inc. 1999 Stock Option Plan (the "Plans"). The Plans
provided for the grant of options to purchase common stock, no par value,
of Network Device Inc. to officers, directors, employees and consultants of
Network Device Inc. However, pursuant to the Agreement and Plan of Merger
among the Registrant, Aries Acquisition Corporation, a Delaware corporation
and wholly owned subsidiary of the Registrant and Network Device Inc.,
dated as of February 10, 2000, these options have each been converted into
an option to purchase a fraction of a share of Common Stock ("Options").

                  This opinion is being furnished in accordance with the
requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

                  In connection with this opinion, I have examined
originals or copies, certified or otherwise identified to my satisfaction,
of (i) the Registration Statement, as filed with the Commission on the date
hereof under the Securities Act; (ii) a specimen certificate representing
the Common Stock; (iii) the Restated Certificate of Incorporation of the
Registrant, as presently in effect; (iv) the Amended and Restated By-Laws
of the Registrant, as presently in effect; (v) certain resolutions of the
Board of Directors of the Registrant relating to the Plans; and (vi) the
Plans. I have also examined originals or copies, certified or otherwise
identified to my satisfaction, of such records of the Registrant and such
other documents, certificates and records as I have deemed necessary or
appropriate as a basis for the opinions set forth herein.

                  In my examination, I have assumed the legal capacity of
all natural persons, the genuineness of all signatures, the authenticity of
all documents submitted to me as originals, the conformity to original
documents of all documents submitted to me as certified, conformed or
photostatic copies and the authenticity of the originals of such copies. In
making my examination of documents executed or to be executed by parties
other than the Registrant, I have assumed that such parties had or will
have the power, corporate or other, to enter into and perform all
obligations thereunder and have also assumed the due authorization by all
requisite action, corporate or other, and execution and delivery by such
parties of such documents and the validity and binding effect thereof on
such parties. As to any facts material to the opinions expressed herein
which I have not independently established or verified, I have relied upon
statements and representations of officers and other representatives of the
Registrant and others. I have assumed that each award agreement setting
forth the terms of each grant of options or other awards under the Plans
will be consistent with the Plans and will be duly authorized and validly
executed and delivered by the parties thereto, and that the consideration
received by the Registrant for the Common Stock delivered pursuant to the
Plans will be in an amount at least equal to the par value of such Common
Stock.

                  I am admitted to the bar in the State of Massachusetts,
and I do not express any opinion as to the laws of any jurisdiction other
than the particular law of the state in which I am admitted to the bar.

                  Based upon and subject to the foregoing, I am of the
opinion that the shares of Common Stock have been duly authorized for
issuance by the Registrant and, when such shares of Common Stock are issued
upon exercise of Options in accordance with the terms of the Plans, such
shares of Common Stock will be validly issued, fully paid and
nonassessable.

                  I hereby consent to the filing of this opinion with the
Commission as an exhibit to the Registration Statement. In giving such
consent, I do not thereby admit that I am included in the category of
persons whose consent is required under Section 7 of the Securities Act or
the rules and regulations of the Commission promulgated thereunder.

                  This opinion is furnished by me, as the Registrant's
corporate counsel, in connection with the filing of the Registration
Statement with the Commission and, except as provided in the immediately
preceding paragraph, is not to be used, circulated, quoted or otherwise
referred to for any other purpose or relied upon by any other person
without my prior written permission.

                                                  Very truly yours,

                                                  /s/ JAMES C. NEMIAH

                                                  JAMES C. NEMIAH
