**Item 6. Indemnification of Directors and Officers.**

Section 102 of the General Corporation Law of the State of Delaware (the "DGCL") allows a corporation to adopt a provision of its certificate of incorporation that limits or eliminates the personal liability of directors and officers of a corporation to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except that no provision may limit or eliminate the liability of (i) a director or officer for a breach of the duty of loyalty, (ii) a director or officer for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) a director for the payment of a dividend or approval of a stock repurchase or redemption in violation of the DGCL, (iv) a director or officer for a transaction from which the director or officer obtained an improper personal benefit, or (v) an officer in an action by or in the right of the corporation, including any derivative action.

Section 145 of the DGCL provides, among other things, that 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, suit or proceeding—other than an action by or in the right of the Company—by reason of the fact that the person is or was a director, officer, employee or agent of the Company, 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, judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding. The power to indemnify applies (a) if such person is successful on the merits or otherwise in defense of any action, suit or proceeding or (b) if such person is acting in good faith and in a manner such person reasonably believed to be in the best interest, or not opposed to the best interest, of the Company, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The power to indemnify applies to actions brought by or in the right of the Company as well as but only to the extent of defense expenses, including attorneys' fees actually and reasonably incurred, but does not apply to judgments or amounts paid in settlement, and with the further limitation that in such actions no indemnification of expenses shall be made in the event of any adjudication of liability to the Company, unless the court believes that in light of all the circumstances indemnification should apply.

Our Certificate of Incorporation eliminates the liability of our directors for monetary damages to us and our stockholders to the fullest extent permitted by law. Our Certificate of Incorporation and Bylaws, as amended and restated, provide that we shall indemnify our directors and officers, including when acting as directors, officers, employees and agents of other enterprises, to the fullest extent permitted by the DGCL.

This letter provides an opinion regarding Cogent Communications Holdings, Inc.'s (the "Company") filing with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Act"), of a Registration Statement on Form S-8 (the "Registration Statement") relating to the proposed issuance by the Company of an additional 1,800,000 shares of the Company's common stock, par value $0.001 per share (the "Shares"), pursuant to the Third Amended and Restated Cogent Communications Holdings, Inc. 2017 Incentive Award Plan (the "Plan"). This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement or related Prospectus, other than as expressly stated herein with respect to the issue of the Shares.

In my capacity as Chief Legal Officer of the Company, I am familiar with the proceedings taken and proposed to be taken by the Company in connection with the authorization, issuance and sale of the Shares, and for purposes of this opinion, have assumed such proceedings will be completed in a timely manner and in the manner presently proposed. In preparing this opinion, I made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to my satisfaction of such documents, corporate records and instruments, as I have deemed necessary or appropriate for purposes of this opinion.

In my examination, I assumed the genuineness of all signatures, the authenticity of all documents submitted to me as originals and the conformity to authentic original documents of all documents submitted to me as copies.

Subject to the foregoing and the other matters as set forth herein, it is my opinion that, as of the date hereof, the issue and sale of the Shares have been duly authorized by all necessary corporate action of the Company, and upon issuance, delivery and payment therefor in the manner contemplated by the Plan, the Shares will be validly issued, fully paid and nonassessable.

This opinion is for your benefit in connection with the Registration Statement. You may rely upon this opinion, as may others who are entitled to rely upon it pursuant to applicable provisions of the Act. I consent to your filing this opinion as an exhibit to the Registration Statement. In giving such consent, I do not admit that I am in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.
