INCORPORATION BY REFERENCE OF EARLIER REGISTRATION STATEMENTS ON FORM S-8

This Registration Statement registers additional shares for offering pursuant to such plan.  Subject to Item 3 of Part II of this Registration Statement and except as modified or superseded herein, the contents of the Earlier Registration Statements are incorporated herein by reference.

PART II

Item 3.  Incorporation of Documents by Reference.

There are hereby incorporated by reference into this Registration Statement the following documents and information heretofore filed with the Securities and Exchange Commission (the “Commission”) by the Registrant:

1.                                      The Registrant’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014;

2.                                      The Registrant’s Quarterly Report on Form 10-Q for the quarters ended March 28, 2015 and June 27, 2015;

4.                                      The description of Registrant’s capital stock contained in the Company’s Registration Statements pursuant to Section 12 of the Exchange Act and any amendments or reports filed for the purpose of updating any such descriptions.

In addition, each document filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act after the date hereof and prior to the filing of a post-effective amendment which indicates that all securities offered hereunder have been sold or which deregisters all securities then remaining unsold under this Registration Statement, shall be deemed to be incorporated by reference herein and to be part hereof from the date of filing of such documents. Any statement contained herein or in a document incorporated herein by reference shall be deemed to be modified or superseded for purposes hereof to the extent that a statement contained herein or in any other subsequently filed document incorporated herein by reference modifies or supersedes such statement.  Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part hereof.

Item 4.                                                         Description of Securities.

Not applicable.

Item 5.                                                         Interests of Named Experts and Counsel.

None.

Item 6.                                                         Indemnification of Directors and Officers.

Section 145(a) of the General Corporation Law of the State of Delaware (the “DGCL”) provides that a Delaware 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, suit or proceeding, whether civil, criminal, administrative or investigative

II-1

(other than an action by or in the right of the corporation) by reason of the fact that such 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 or enterprise, against expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person 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 cause to believe his conduct was unlawful.

Section 145(b) of the DGCL provides that a Delaware 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 such person acted in any of the capacities set forth above, against expenses actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if he or she acted under similar standards to those set forth above, except that no indemnification may be made in respect to 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 in which such action or suit was brought shall determine that despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to be indemnified for such expenses that the court shall deem proper.

Section 145 of the DGCL further provides that to the extent a director or officer of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsection (a) and (b) or in the defense of any claim, issue or matter therein, he or she shall be indemnified against expenses actually and reasonably incurred by him or her in connection therewith; 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 the corporation may purchase and maintain insurance on behalf of a director or officer of the corporation against any liability asserted against such officer or director and incurred by him or her in any such capacity or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liabilities under Section 145.

As permitted by Section 102(b)(7) of the DGCL, the Registrant’s Certificate of Incorporation provides that a director shall not be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director. However, such provision does not eliminate or limit the liability of a director: (i) for any breach of the director’s duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of the law, (iii) under Section 174 of the DGCL, or (iv) for engaging in any transaction from which the director derived an improper personal benefit. The Registrant’s Certificate of Incorporation requires that directors and officers be indemnified to the maximum extent permitted by Delaware law.

The Registrant has a policy of directors’ liability insurance, which insures the directors and officers against the cost of defense, settlement or payment of a judgment under certain circumstances.

Item 7.                                                         Exemption from Registration Claimed.

Not applicable.

Item 8.                                                         Exhibits.

See Index to Exhibits.

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:

II-2

(i)            To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(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;

(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 periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this 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 Registrant hereby undertakes that, for purposes of determining liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new Registration Statement relating to the securities offering 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 of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions described in Item 6 of this Registration Statement, 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.

Re:          Registration Statement on Form S-8

Ladies and Gentlemen:

We have acted as counsel to SPX Corporation, a Delaware corporation (the “Corporation”), in connection with the filing of a Registration Statement on Form S-8 by the Corporation under the Securities Act of 1933, as amended (the “Registration Statement”), which Registration Statement registers 1,150,000 shares of Common Stock, par value $.01 per share (the “Common Stock”), reserved for issuance under the Corporation’s 2002 Stock Compensation Plan (the “Plan”).  In that capacity, we have reviewed the Certificate of Incorporation and Bylaws of the Corporation, both as amended to date, the Registration Statement, the Plan, originals or copies of corporate records reflecting the corporate action taken by the Corporation in connection with the approval of the Plan and the issuance of the Common Stock under the Plan and such other instruments as we have deemed necessary for the issuance of this opinion.

Based upon the foregoing, we are of the opinion that the shares of Common Stock to be offered under the Plan have been duly authorized by all requisite action on the part of the Corporation and, when issued in accordance with the terms and conditions of the Plan, will be legally issued, fully paid and non-assessable.

We consent to the filing of this opinion as an exhibit to the Registration Statement.  In giving this consent, we do not admit that we are within the category of persons whose consent is required by Section 7 of the Securities Act of 1933, as amended.
