     The documents containing the information specified in Part I of Form S-8 are not required to be filed with the Securities and Exchange Commission (the "SEC") either as part of this Registration Statement or as prospectuses or prospectus supplements pursuant to the Note to Part I of Form S-8 and Rule 424 under the Securities Act of 1933, as amended (the “Securities Act”). The information regarding each Plan required in the Section 10(a) prospectus is included in documents being maintained and delivered by EMCOR Group, Inc. as required by Part I of Form S-8 and by Rule 428 under the Securities Act.

PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference

     The following documents which have been and will in the future be filed by us with the SEC are incorporated in this Registration Statement by reference:

1.	Our Annual Report on Form 10-K for the fiscal year ended December 31, 2009, which contains our audited financial statements for the fiscal year ended December 31, 2009.
2.	All other reports filed by us pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) since December 31, 2009.
3.	The description of our common shares contained in our Registration Statement on Form 10-12G/A under the Exchange Act, as filed with the SEC on August 11, 1995 (File No. 0-2315), including any amendment or report filed for the purpose of amending such description.

     In addition, all reports and documents subsequently filed by us under Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, after the date of this Registration Statement and prior to the filing of a post-effective amendment which indicates that all securities being offered have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in and to be part of this Registration Statement from the filing date of each such document.

     Any statement contained in a document incorporated by reference or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any subsequently filed document which also is deemed to be incorporated by reference herein 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 Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 4. Description of Securities

     Not Applicable.

Item 5. Interests of Named Experts and Counsel

     Sheldon I. Cammaker, our Executive Vice President, General Counsel and Secretary, has provided an opinion to us as to the validity of the shares of our common stock being registered by this Registration Statement on Form S-8. Mr. Cammaker may be awarded shares, other awards, or options to purchase shares under the 2010 Incentive Plan.

Item 6. Indemnification of Directors and Officers

     Our Restated Certificate of Incorporation provides, as do the charters of many other publicly held companies, that the personal liability of our directors to us is eliminated to the

2

maximum extent permitted by the Delaware General Corporation Law. Our Restated Certificate of Incorporation and By-Laws provide for the indemnification of our, and our subsidiaries’, directors, officers, employees, and agents to the fullest extent that may be permitted by the Delaware General Corporation Law from time to time, and the By-Laws provide for various procedures relating thereto. Certain provisions of our Restated Certificate of Incorporation protect our directors against personal liability for monetary damages resulting from breaches of their fiduciary duty as a director, except as set forth below. Under the Delaware General Corporation Law, absent these provisions, directors could be held liable for gross negligence in the performance of their duty of care, but not for simple negligence. Our Restated Certificate of Incorporation absolves directors of liability for negligence in the performance of their duties, including gross negligence. However, our directors remain liable for breaches of their duty of loyalty to us and our stockholders, as well as for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law and transactions from which a director derives improper personal benefit. Our Restated Certificate of Incorporation also does not absolve directors of liability under Section 174 of the Delaware General Corporation Law, which makes directors personally liable for unlawful dividends or unlawful stock repurchases or redemptions in certain circumstances and expressly sets forth a negligence standard with respect to such liability.

     Under the Delaware General Corporation Law, directors, officers, employees and other individuals may be indemnified against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation (a “derivative action”)) if they acted in good faith and in a manner they reasonably believed to be in or not opposed to our best interest and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. A similar standard of care is applicable in the case of a derivative action, except that indemnification only extends to expenses (including attorneys’ fees) incurred in connection with the defense or settlement of such an action and the Delaware General Corporation Law requires court approval before there can be any indemnification of expenses where the person seeking indemnification has been found liable to us.

     Our Restated Certificate of Incorporation and By-laws provide, among other things, that each person who was or is made a party to, or is threatened to be made a party to, any pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by us or in our right), by reason of the fact that he or she is or was a director or officer of us (or was serving at our request as a director, officer, employee, or agent for another entity, including an employee benefit plan), will be indemnified and held harmless by us to the fullest extent authorized by the Delaware General Corporation Law against all expense, liability, or loss (including attorneys’ fees, judgments, fines, and amounts to be paid in settlement) reasonably incurred by such person in connection therewith. The rights conferred thereby will be deemed to be contract rights and will include the rights to be paid by us for the expenses incurred in defending the proceedings specified above in advance of their final disposition.

     We are a party to an indemnification agreement with each of our directors and executive officers. These indemnification agreements provide for, among other things, the indemnification by us of our directors and executive officers to the fullest extent permitted by law and the advancement of attorneys’ fees and expenses. The agreements also state that in the event of a potential change in control, we shall establish trusts, which are irrevocable except upon the indemnitees’ written consent, to fund our indemnification obligations thereunder.

3

     Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors and officers and persons controlling us pursuant to the above provisions, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. We carry certain insurance coverage, in respect of potential claims against our directors and officers and in respect of losses of which we may be required or permitted by law to indemnify such directors and officers.

Item 7. Exemption from Registration Claimed

     Not Applicable.

Item 8. Exhibits

     A list of exhibits included as part of this registration statement is set forth in the Exhibit Index which immediately precedes such exhibits and is hereby incorporated by reference herein.

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 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 is 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 SEC pursuant to Rule 424(b) of 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; and

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

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above 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 SEC 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 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

4

          (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, as amended, 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 SEC 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 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 Securities Act and will be governed by the final adjudication of such issue.
