INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Under the CBCA and pursuant to the current bylaws, we will indemnify a director or officer or a former director or officer or another individual who acts or acted at our request as a director or officer, or an individual acting in a similar capacity of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with us or another entity. In order to qualify for indemnification such director or officer or other individual must have (i) acted honestly and in good faith with a view to our best interests or, as the case may be, the other entity for which the individual acted as director or officer or in a similar capacity; and (ii) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, had reasonable grounds for believing that his conduct was lawful.

The CBCA also provides that such persons are entitled to indemnity from us in respect of all costs, charges and expenses reasonably incurred by the individual in connection with the defense of any civil, criminal, administrative, investigative or other proceeding to which the individual is subject because of the individual’s association with us or other entity, if the individual was not judged by the court or other competent authority to have committed any fault or omitted to do anything that the person ought to have done and otherwise fulfills the conditions for indemnity described above.

We may advance moneys to an individual for the costs, charges and expenses of a proceeding referred to above. The individual is required to repay the moneys if the individual does not fulfill the conditions for indemnity described above.

The proposed certificate of incorporation of Revett Mining Company, Inc. includes a provision that eliminates the personal liability of the directors for monetary damages to the fullest extent permitted by Delaware law. Under current Delaware law, a director’s liability to a corporation and its stockholders may not be limited for:

• a breach of the director’s duty of loyalty to the corporation or its stockholders;

• acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

• an unlawful payment of a dividend or an unlawful stock purchase or redemption; and

• any transaction from which the director derived an improper personal benefit.

The proposed bylaws of Revett Mining Company, Inc. generally provide for mandatory indemnification and advancement of expenses of our directors and officers to the fullest extent permitted under Delaware law; provided, however, that directors and officers shall not be entitled to indemnification for actions initiated by such parties unless the board of directors authorizes such action.

Currently, there is no pending litigation or proceeding involving any of our Corporation’s directors or executive officers for which indemnification is sought, nor are we aware of any threatened litigation that may result in claims for indemnification. We have directors’ and officers’ liability insurance and Revett Mining Company, Inc. intends to maintain the directors’ and officers’ liability insurance.

Item 22. 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 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;
	(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.
	*
	*
	(6)	that, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

II - 4

(i)	any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii)	any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii)	the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv)	any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(i)	The undersigned registrant hereby undertakes that:
	(1)	for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.
	(2)	for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus 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.

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 Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, Revett Minerals Inc. has duly caused this Amendment No. 4 to Registration Statement on Form S-4 to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Spokane Valley, Washington on December 9, 2013.
