corporation to indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right
of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The indemnity
may include expenses (including attorney fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a
manner he reasonably believed to be in or not opposed to the corporation&#146;s best interests and, for criminal proceedings, had no reasonable cause to believe his conduct was unlawful. A Delaware corporation may indemnify directors, officers, employees
and agents in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the person is adjudged to be liable to the corporation in the performance of his duty. Where
an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against expenses that such officer or director actually and reasonably incurred.</FONT></DIV>

damages for breach of fiduciary duty as director except for liability (i) for any breach of the director&#146;s duty of loyalty to the Company or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or

OM Group, Inc. (the "Company") incorporates by reference into this registration statement the following
documents:
(a)
The Company's Annual Report on Form 10-K for the year ended December 31, 1999;
(b)
All other reports filed by the Company pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), since the end of the fiscal year covered by the Annual Report on Form 10-K referred to in (a) above; and
(c)
The description of the Company's Common Stock, $.01 par value, contained in the Company's Form 8-A Registration Statement
filed October 12, 1993 under Section 12 of the Exchange Act.
All documents subsequently filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange
Act, prior to the filing of a post-effective amendment that indicates that all securities offered have been sold, or that deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in this registration statement and
to be part hereof from the date of filing of such documents.
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 General Corporation Law of the State of Delaware ("Delaware Law") empowers a Delaware
corporation to indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right
of such corporation), by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise. The indemnity
may include expenses (including attorney fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such person acted in good faith and in a
manner he reasonably believed to be in or not opposed to the corporation's best interests and, for criminal proceedings, had no reasonable cause to believe his conduct was unlawful. A Delaware corporation may indemnify directors, officers, employees
and agents in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the person is adjudged to be liable to the corporation in the performance of his duty. Where
an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against expenses that such officer or director actually and reasonably incurred.
In accordance with Delaware Law, Article Eighth of the Company's Restated Certificate of Incorporation
contains a provision limiting the personal liability of the Company's directors for violations of their fiduciary duty. Such provision states that no director of the Company will be personally liable to the Company or its stockholders for monetary
damages for breach of fiduciary duty as director except for liability (i) for any breach of the director's duty of loyalty to the Company or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or
knowing violation of law, (iii) for a violation of Section 174 of the Delaware Law or (iv) for a transaction from which the director derived an improper personal benefit.
Article Seventh of the Company's Restated Certificate of Incorporation and Article VII of the Company's
By-Laws provide for indemnification of the Company's officers and directors to the fullest extent permitted by applicable law.
The Company maintains insurance policies that insure the Company's directors and officers against certain
liabilities that might be incurred by reason of their positions as directors and officers.

Item 9.    Undertakings
(a)
The Company 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
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) do not apply if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed by the Company pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference 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; and
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the
termination of the offering.
(b)
The Company hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of its
annual report pursuant to Section 13(a) or 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 Company, the Company 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 Company of expenses incurred or paid by a director, officer or controlling person of the Company 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 Company 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.
