         Section 5. This option shall become exercisable as to all of the shares

provided that this option shall not be exercisable prior to the expiration of
six months from the date of grant.

         Section 6. To the extent not otherwise exercisable at the date of the
retirement of the Participant in accordance with a retirement plan or policy of

         Section 7. If the Participant shall die while still employed by the

Participant's death (but only within the option period specified in Section 11).

         Section 8. If the Participant ceases to be employed by the Company or a

option shall become fully exercisable to the extent not otherwise exercisable,

employment (but only within the option period set forth in Section 11).

         Section 9. If the Participant shall die following the cessation of

in Sections 6 or 8, this option shall become fully exercisable to the extent not

         Section 10. If the Participant ceases to be employed by the Company or
a subsidiary for any reason other than retirement, permanent and total
disability, or death, the Participant may exercise the option rights set forth
herein at any time within the three-month period following such cessation of
employment (but only within the option period specified in Section 11) to the
extent the Participant was entitled to exercise the same immediately prior to
such cessation of employment; provided, however, if there has been a Change in
Control of the Company and the Participant's employment with the Company shall
have terminated after such Change in Control and prior to six months from the
date of grant of this option, then this option may be exercised in whole or in
part at any time within the three-month period commencing six months from the
date of grant of this option.

         Section 11. Notwithstanding any other provisions hereof, this option

         Section 12. Notwithstanding any other provisions hereof, if the
Participant's employment with the Company or a subsidiary is terminated on

         Section 13. This option is not transferable by the Participant
otherwise than by will or by the laws of descent and distribution, and is
exercisable, during the lifetime of the Participant, only by the Participant or
the Participant's guardian or legal representative. Upon any attempt to
transfer, assign, pledge, hypothecate, or otherwise dispose of this option or
the related option rights contrary to the provisions of this Agreement, or upon
the levy of any attachment or similar process upon such option or rights, such
option and rights shall immediately become null and void.

         Section 14. If the Participant's exercise of this option is prevented
by the terms of subsections (a), (b) or (c) of Section 18 and the Participant's
option terminates pursuant to Section 6, 8 or 9, then the Participant may,
notwithstanding the provisions of Section 6, 8 or 9 but only within the period
set forth in Section 11, exercise such option to the extent it would have been
exercisable immediately prior to its termination but for the operation of
Section 18 at

                                     - 2 -
<PAGE>

any time within 30 days after such Participant is notified by the Company that
such exercise is no longer prevented by Section 18.

         Section 15. In the event that at any time prior to the expiration of
this option each of the outstanding shares of Common Stock of the Company
(except shares held by dissenting stockholders) shall be changed into or
exchanged for a different number or kind of shares of stock or other securities
of the Company or of another corporation, whether through reorganization,
recapitalization, stock split-up, combination of shares, merger or
consolidation, then for all purposes of this option there shall be substituted
for each share of Common Stock purchasable hereunder the number and kind of
shares of stock or other securities into which each such share of Common Stock
of the Company shall be so changed, or for which each such share shall be so
exchanged, and the shares or securities so substituted for each such share of
Common Stock shall be subject to purchase at an appropriately adjusted option
exercise price and subject to the terms and conditions hereof.

         In the event that the Company shall issue a stock dividend in Common
Stock with respect to the Common Stock of the Company, the number of shares then
purchasable hereunder shall be adjusted by adding to each such share the number
of shares which would have been distributed as a stock dividend thereon had such
share been outstanding on the record date for payment of the stock dividend, and
each such share together with said additional shares shall be purchasable at the
option exercise price as above provided and as may be appropriately adjusted.

         In the event that there shall be any other change in the number or kind
of outstanding shares of Common Stock or other securities of the Company, or of
any shares of stock or other securities into which such shares of Common Stock
shall have been changed or for which they shall have been exchanged, or the
Company shall make an Extraordinary Distribution or a Prorata Repurchase, then
the Compensation Committee shall make such adjustment in the number or kind of
shares of stock or other securities covered by this option and in the number or
kind of shares of stock or other securities subject to purchase at the option
exercise price as above provided and with any such adjustment in the option
exercise price to reflect the effect of such Extraordinary Distribution or
Prorata Repurchase as the Compensation Committee, in its sole discretion may
determine is equitably required by such change, and such adjustment so made
shall be effective and binding for all purposes of this option.

         Anything to the contrary herein contained notwithstanding, the
Participant shall not be entitled to purchase a fraction of a share under this
option.

         Section 16. If the Company shall liquidate or dissolve, or shall be a
party to a merger or consolidation with respect to which the Company shall not
be the surviving corporation, the Company shall give written notice thereof to
the Participant at least 30 days prior thereto. The Participant shall have the
right within said 30-day period (but only within the period specified in Section
11) to exercise this option to the extent such Participant was entitled to
exercise the option on the date of the notice; provided, however, that if the
Participant is employed by the Company on the date of the notice, then
notwithstanding the provisions of Section 4, the Participant shall have the
right to exercise this option in full to the extent not previously exercised. To
the extent that this option shall not have been exercised on or prior to the
effective date of such liquidation, dissolution, merger or consolidation, then
notwithstanding any other

                                     - 3 -
<PAGE>

provisions hereof, it shall terminate on said date, unless it is assumed by
another corporation within the meaning of Section 425(a) of the Internal
Revenue Code of 1986, as amended.

         Section 17. Subject to the terms and conditions hereof, this option may
be exercised in whole or in part by delivering to the Company at its principal
place of business a written notice, signed by the person entitled to exercise
the option, of the election to exercise the option and stating the number of
shares to be purchased. Such notice shall, as an essential part thereof, be
accompanied by the payment of the full option exercise price of the shares then
to be purchased, except as provided below. Payment of the full option exercise
price may be made, at the election of the Participant, in (a) cash, (b) Common
Stock of the Company, or (c) any combination of cash or Common Stock of the
Company; provided, however, that the Participant may not use Common Stock of the
Company in payment of the purchase price unless such Common Stock has been held
by the Participant for at least six months. A Participant using Common Stock of
the Company to pay the purchase price of shares being purchased may do so either
by actual delivery of share certificates for such Common Stock or by attesting
as to the ownership of such Common Stock. Shares of Common Stock used in payment
of the purchase price shall be valued at their closing price on the New York
Stock Exchange on the trading day immediately preceding the date of exercise.
The Participant may elect to pay the purchase price upon the exercise of this
option by authorizing a third party to sell all the shares (or a sufficient
portion of the shares) acquired upon the exercise of the option and to remit to
the Company a sufficient portion of the sale proceeds to pay the entire purchase
price and any tax withholding resulting from such exercise. Upon the proper
exercise of this option, the Company shall issue in the name of the person
exercising the option, and deliver to such person, a certificate or certificates
for the shares purchased, provided that if any applicable law or regulation
requires the Company to take any action with respect to the shares specified in
such notice before the issuance thereof, the date of delivery of such shares
shall be extended for the period necessary to take such action. The Participant
agrees that as holder of this option, the Participant shall have no rights as a
stockholder or otherwise in respect of any of the option shares until the option
is effectively exercised as herein provided. The Participant agrees to pay in
cash, within the time period specified by the Company, the amount (if any)
required to be withheld for federal, state and local tax purposes on account of
the exercise of the option or to make such arrangements to satisfy such
withholding requirements as the Company deems appropriate.

         Section 18. This option shall not be exercisable if such exercise would
violate:

         (a)     Any applicable state securities law;

         (b)     Any applicable registration or other requirements under the
                 Securities Act of 1933, as amended (the "Act"), the Securities
                 Exchange Act of 1934, as amended, or applicable listing
                 requirements of any stock exchange; or

         (c)     Any applicable legal requirement of any other governmental
                 authority.

         The Company agrees to make reasonable efforts to comply with the
foregoing laws and requirements so as to permit the exercise of this option.
Furthermore, if a registration statement with respect to the shares to be issued
upon the exercise of this option is not in effect or if counsel for the Company
deems it necessary or desirable in order to avoid possible violation of the Act,
the Company may require, as a condition to its issuance and delivery of
certificates for the shares, the delivery to the Company of a commitment in
writing by the person exercising the

                                     - 4 -
<PAGE>

option that at the time of such exercise it is such person's intention to
acquire such shares for such person's own account for investment only and not
with a view to, or for resale in connection with, the distribution thereof; that
such person understands the shares may be "restricted securities" as defined in
Rule 144 of the Securities and Exchange Commission; and that any resale,
transfer or other disposition of said shares will be accomplished only in
compliance with Rule 144, the Act, or the other rules and regulations
thereunder. The Company may place on the certificates evidencing such shares an
appropriate legend reflecting the aforesaid commitment and the Company may
refuse to permit transfer of such certificates until it has been furnished
evidence satisfactory to it that no violation of the Act or the rules and
regulations thereunder would be involved in such transfer.

         Section 19. This Agreement is subject to the terms of the Plan. If
there is any inconsistency between this Agreement and the Plan, the Plan shall
govern.

         IN WITNESS WHEREOF, the parties hereto have executed this Agreement in
duplicate as of the day and year first above written.

                           RESTRICTED STOCK AGREEMENT

         THIS RESTRICTED STOCK AGREEMENT is entered into this _______ day of
August, 2005 but effective as of June 13, 2005 (being the grant date of this
restricted stock award), between OM Group, Inc., a Delaware corporation (the
"Company"), and Joseph M. Scaminace (the "Executive").

         WHEREAS, the Company maintains the 1998 Long-Term Incentive
Compensation Plan (the "Plan") for the purpose of (i) motivating executive
personnel by means of long-term incentive compensation, (ii) furthering the
identity of interests of participants with those of the shareholders of the
Company through ownership and performance of the common stock of the Company,
and (iii) permitting the Company to attract and retain directors and executive
personnel upon whose judgment the successful conduct of the business of the
Company largely depends.

         WHEREAS, pursuant to the terms of the Plan, the terms, conditions and
restrictions of each restricted stock award is to be set forth in an award
agreement.

         NOW, THEREFORE, the Company and the Executive agree as follows:

         1. Award of Restricted Stock.

         Subject to the terms, conditions and restrictions set forth in this
Agreement, the Company hereby grants to the Executive an award of 166,194 shares
of common stock of the Company (the "Restricted Stock").

         2. Restrictions on Transfer of Restricted Stock.

         The Executive shall not be entitled to sell, exchange, transfer,
pledge, hypothecate, assign or otherwise dispose of the Restricted Stock until
such time that such Restricted Stock has vested in accordance with this
Agreement. Any attempted sale, exchange, transfer, pledge, hypothecation,
assignment or other disposition of such Restricted Stock in violation of this
Agreement shall be void and of no effect and the Company shall have the right to
disregard the same on its books and records.

         3.  Issuance of Stock Certificate.

         The Company shall cause a certificate evidencing the Restricted Stock
to be issued in the name of the Executive following execution of this Agreement.
Such certificate shall bear the following legend, together with any other legend
deemed necessary or desirable by the Company in order to comply with applicable
laws or to ensure the enforceability of the provisions of the Plan or this
Agreement:

<PAGE>

              The sale or other transfer of the shares represented by this
              certificate is subject to certain restrictions set forth in the
              Restricted Stock Agreement between Joseph M. Scaminace (the
              registered owner) and OM Group, Inc., effective as of June 13,
              2005 under the OM Group, Inc. 1998 Long-Term Incentive
              Compensation Plan. A copy of such restrictions may be obtained
              from the Secretary of OM Group, Inc.

Such stock certificate shall be held by the Company (or its designated agent) on
behalf of the Executive until such time as the Restricted Stock has vested or is
forfeited in accordance with this Agreement.

         4. Rights Relating to Restricted Stock.

         The Restricted Stock shall constitute issued and outstanding shares of
common stock of the Company, and the Executive shall be entitled to exercise
voting rights pertaining to the Restricted Stock. In the event dividends are
paid by the Company with respect to the Restricted Stock prior to such time as
the Restricted Stock has vested in accordance with this Agreement, such
dividends shall be distributed to and held by the Company (or its designated
agent) in the same manner as the Restricted Stock and be distributed to the
Executive upon vesting of the Restricted Stock or forfeited in accordance with
this Agreement. In the event that shares of common stock of the Company are
distributed to owners of outstanding common stock by reason of a stock dividend,
stock split, recapitalization or otherwise, such shares received by the
Executive shall be encompassed within the term "Restricted Stock" for purposes
of this Agreement and the Executive shall deliver to the Company all such shares
received, to be held by the Company on behalf of the Executive subject to the
same restrictions as the Restricted Stock.

         5. Vesting.

                  5.1  Vesting Date; Forfeiture; New Certificates.

                  (a) The Restricted Stock granted to the Executive pursuant to
this Agreement shall vest, such that the restrictions set forth in this
Agreement shall no longer be applicable and the Restricted Stock shall no longer
be subject to forfeiture as provided in this Agreement, on June 13, 2008 (the
"Vesting Date").

                  (b) In the event the Executive ceases to be employed by the
Company for any reason prior to the Vesting Date, the Executive shall forfeit to
the Company, without compensation or any other consideration, all Restricted
Stock that is granted pursuant to this Agreement. For purposes of this
Agreement, the Executive shall have ceased to be employed by the Company when he
no longer has the right or obligation to perform services for the Company,
notwithstanding the continuation of any employment agreement for any other
purpose or the continuation of compensation or benefits under any such
employment agreement or otherwise.

                                      -2-

<PAGE>

                   (c) In the absence of a prior forfeiture of the Restricted
Stock pursuant to this Agreement, as promptly as practicable after the Vesting
Date and compliance with Section 6 of this Agreement, the Company shall cause a
new certificate or certificates to be issued in the name of the Executive, or
his designee, in exchange for the certificate for the Restricted Stock that is
described in Section 3 of this Agreement. Such new certificate shall not contain
the legend set forth in Section 3 of this Agreement but may contain any other
legend the Company believes is appropriate in order to comply with applicable
securities law requirements.

         5.2 Accelerated Vesting upon Change in Control. Upon a Change in
Control (as defined in the Plan) of the Company prior to the Vesting Date,
vesting of the Restricted Stock subject to this Agreement shall be accelerated
in accordance with the provisions of Section 24(c) of the Plan, assuming the
Executive is employed by the Company at the time of such Change in Control.

         6. Tax Provision. Executive agrees that, no later than the date upon
which the Restricted Stock becomes vested in accordance with this Agreement, the
Executive will pay to the Company, or make arrangements satisfactory to the
Company regarding payment of, any federal, state or local taxes of any kind
required by law to be paid and/or withheld with respect to such Restricted
Stock.

         7. Special Incentive Compensation.

         The Executive agrees that the award of the Restricted Stock under the
Agreement is special incentive compensation and that it, any dividends paid
thereon (even if treated as compensation for tax purposes) and any other
property received on account of such Restricted Stock will not be taken into
account as "salary" or "compensation" or "bonus" in determining the amount of
any payment under any pension, retirement or profit-sharing plan of the Company
or any life insurance, disability or other benefit plan of the Company.

         8. Relationship to the Plan.

         This Agreement is subject to the terms of the Plan and any related
administrative policies adopted by the Company. If there is any inconsistency
between this Agreement and the Plan or any such administrative policies, the
Plan and the policies, in that order, shall govern.

         9. No Effect on Employment Relationship.

         Executive's employment relationship with the Company is the subject of
a separate employment agreement and nothing in this Agreement shall interfere
with or affect the rights of the Company and the Executive under that employment
agreement or confer upon the Executive any right to continued employment with
the Company.

         10. Binding Effect.

         Subject to the provisions of the Plan, this Agreement shall inure to
the benefit of and be binding upon the Executive and the Company and their
respective heirs, legal representatives, successors and assigns.

         11. Amendment.

         No amendment, modification, waiver or release of or under this
Agreement will be effective unless evidenced by an instrument in writing signed
by each of the Company and the Executive.

         12. Governing Law.
