“In
respect of the Term Loans only, if at any time the Administrative Agent determines (which determination shall be conclusive absent manifest
error) that the supervisor for the administrator of the Eurocurrency Rate or a Governmental Authority having jurisdiction over the Administrative
Agent has made a public statement identifying a specific date after which the Eurocurrency Rate shall no longer be used for determining
interest rates for loans (an “Alternative Interest Rate Election Event”), the Administrative Agent and the Borrowers
shall be entitled to establish an alternate rate of interest to the Eurocurrency Rate or from time to time further update any provisions
applicable to such alternate rate of interest that, in each case, gives due consideration to the then prevailing market convention for
determining a rate of interest for leveraged syndicated loans in the United States at such time (including the adoption of any rate of
interest and related adjustments recommended by the Alternative Reference Rates Committee from time to time), and shall enter into an
amendment to this Agreement to reflect such alternate rate of interest and such other related changes to this Agreement as may be applicable,
which amendment shall be (i) reasonably 

    	 	- 7 -	Orion - Ninth Amendment to the Credit Agreement

     

    

acceptable to the Borrowers and the Administrative Agent and (ii) made in a manner that is intended
to comply with the terms of the Proposed United States Treasury Regulations under Section 1.1001-6 (or any successor United States Treasury
Regulations or other official Internal Revenue Service guidance promulgated that supersedes such Proposed United States Treasury Regulations).
Notwithstanding anything to the contrary in Section 10.02, such amendment shall become effective so long as the Administrative
Agent does not receive objections from the Required Lenders (excluding Required Lenders under paragraph (c) of such definition) within
five (5) Business Days of posting of the proposed amendment. To the extent an alternate rate of interest is adopted as contemplated hereby,
the approved rate shall be applied in a manner consistent with prevailing market convention; provided that, to the extent such
prevailing market convention is not administratively feasible for the Administrative Agent, such approved rate shall be applied in a
manner as otherwise reasonably determined by the Administrative Agent and the Borrowers and subject to the Administrative Agent not receiving
objections from the Required Lenders (excluding Required Lenders under paragraph (c) of such definition) within five (5) Business Days
of posting of the proposed amendment. From such time as an Alternative Interest Rate Election Event has occurred and continuing until
an alternate rate of interest has been determined in accordance with the terms and conditions of this Section 3.05(e), (x)
any Committed Loan Notice that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurocurrency Loan
shall be ineffective, and (y) if any Committed Loan Notice requests a LIBOR Loan, such Borrowing shall be made as a Base Rate
Loan; provided that clauses (x) and (y) of this sentence shall apply during such period only if the Eurocurrency
Rate for such Interest Period is not available or published at such time on a current basis. Notwithstanding anything contained herein
to the contrary, in no event shall such alternate rate of interest as determined in this Section 3.05(e) be less than 0.00% per
annum.

Dear
Sirs

Orion
Engineered Carbons GmbH – $[●] (equivalent) Credit Agreement dated [●] (as amended) (the Credit Agreement)

		1.	We
                                            refer to the Credit Agreement. This is an Annual ESG Compliance Certificate. Terms defined
                                            in the Credit Agreement have the same meaning when used in this Annual ESG Compliance Certificate
                                            unless given a different meaning in this Annual ESG Compliance Certificate.

		2.	We
                                            confirm that at the end of the Fiscal Year to which this Annual ESG Compliance Certificate
                                            relates: the (i) the NOx Emissions Target for such Fiscal year [was]/[was not] met and/or
                                            the (ii) SO2 Emissions Target for such Fiscal Year [was]/[was not] met, therefore the Applicable
                                            Rate with respect to Initial Dollar Term Loans should be (x) [●]% per annum for Eurocurrency
                                            Rate Loans and (y) [●]% for Base Rate Loans.

SECTION
3. References to Initial Term Loans.On and after the Ninth Amendment Effective Date, unless the context shall otherwise require,
each reference in the Existing Credit Agreement or any other Loan Document to (a) “Initial Euro Term Loans” shall be deemed
a reference to the Refinancing Term Loans denominated in Euro contemplated hereby and the terms “Initial Euro Term Borrowing”
and “Initial Euro Term Commitment” shall be deemed to have corresponding meanings, (b) “Initial Dollar Term Loans”
shall be deemed a reference to the Refinancing Term Loans denominated in Dollars contemplated hereby and the terms “Initial Dollar
Term Borrowing” and “Initial Dollar Term Commitment” shall be deemed to have corresponding meanings, and (c) “Lenders”
shall be deemed to include the New Term Lenders. As of the Ninth Amendment Effective Date, after giving effect to this Amendment (after
giving effect to any principal amortization payments made on or prior to the Ninth Amendment Effective Date), the aggregate outstanding
principal amount of the Initial Euro Term Loans is €300,000,000 and the aggregate outstanding principal amount of the Initial Dollar
Term Loans is $300,000,000.

SECTION
4. Exchange of Existing Term Loans. On the terms and subject to the satisfaction (or waiver) of the conditions set forth in Section
7 hereof, each Exchanging Term Lender agrees that an aggregate principal amount of its Existing Term Loans (the “Exchanged
Term Loans”) equal to the amount of such Exchanging Term Lender’s Existing Term Loans (or such lesser amount notified
to such Exchanging Term Lender by the Administrative Agent) will be exchanged with Refinancing Term Loans in the same currency, as further
described in such Exchanging Term Lender’s Lender Consent, as of the Ninth Amendment Effective Date. Each Exchanging Lender hereby
confirms that no amounts shall be payable under Section 3.06 of the Existing Credit Agreement as a result of the exchange of its Existing
Term Loans for the Exchanged Term Loans taking place on a day other than the last day of the applicable Interest Period for its Existing
Term Loans.

    	 	- 10 -	Orion - Ninth Amendment to the Credit Agreement

     

    

SECTION
5. Prepayment of Existing Term Loans. On the Ninth Amendment Effective Date, the Term Borrowers shall apply the Net Proceeds of
the Refinancing Term Loans (if any), together with cash on hand, to prepay in full the outstanding principal amount of all Non-Exchanged
Term Loans, to pay accrued and unpaid interest payable on all Existing Term Loans to (and excluding) the Ninth Amendment Effective Date
and (if applicable) to pay amounts owing on the Non-Exchanged Term Loans under Section 3.06 of the Existing Credit Agreement, in each
case as of the Ninth Amendment Effective Date. The exchange of Exchanged Term Loans with Refinancing Term Loans contemplated hereby collectively
constitute a voluntary prepayment of the Existing Term Loans by the Borrower pursuant to Section 2.05(a) of the Existing Credit Agreement
and the New Term Lenders hereby agree that this Amendment shall be deemed to satisfy all requirements under Section 2.05(a) for such
voluntary prepayment. The refinancing undertakings of the Exchanging Term Lenders are several and no such New Term Lender will be responsible
for any other New Term Lender’s failure to make or acquire by refinancing Refinancing Term Loans. Each of the parties hereto acknowledges
and agrees that the terms of this Amendment do not constitute a novation but, rather, an amendment of the terms of a pre-existing Indebtedness
and related agreement, as evidenced by the Amended Credit Agreement.

SECTION
6. Interest, Rollover and Break Costs. Each party hereto agrees that:

(a)
the Refinancing Term Loans shall be deemed to have an initial Interest Period (the “Initial Interest Period”) that
begins on the Ninth Amendment Effective Date and ends on the last day of the interest period for the Existing Term Loans in the same
currency in effect under the Existing Credit Agreement immediately prior to the Ninth Amendment Effective Date (the “Existing
Interest Period”), such last day being September 30, 2021 and after the Initial Interest Period each Interest Period for the
Refinancing Term Loans shall be determined in accordance with the terms of the Amended Credit Agreement;

(b)
for the Initial Interest Period the Refinancing Term Loans shall be deemed to accrue interest from (and including) the Ninth Amendment
Effective Date in accordance with paragraph (c) below and after the Initial Interest Period the Refinancing Term Loans shall accrue interest
in accordance with the terms of the Amended Credit Agreement;

(c)
for the Initial Interest Period the Eurocurrency Rate and Base Rate in respect of the Refinancing Term Loans shall be deemed to be equal
to the Eurocurrency Rate and Base Rate in respect of the Existing Term Loans in the same currency for the Existing Interest Period (as
in effect immediately prior to the Ninth Amendment Effective Date), provided that decreases (if any) to the Applicable Rate and interest
rate floors within the definitions of Eurocurrency Rate and/or Base Rate in this Amendment or the Amended Credit Agreement shall be given
effect for the Initial Interest Period in respect of the Refinancing Term Loans from and including the Ninth Amendment Effective Date;

(d)
any accrued and unpaid interest to (and excluding) the Ninth Amendment Effective Date on any Existing Term Loans shall be paid in cash
by the relevant Borrowers to the Administrative Agent, for the account of the relevant Lenders on the Ninth Amendment Effective Date;

(e)
amounts due and payable under Section 3.06 of the Existing Credit Agreement in respect of Non-Exchanged Term Loans shall be paid in cash
by the relevant Borrowers to the Administrative Agent, for the account of the relevant Lenders on the Ninth Amendment Effective Date;
and

(f)
each Exchanging Term Lender hereby confirms that no amounts shall be payable under Section 3.06 of the Existing Credit Agreement as a
result of the exchange of its Existing Term Loans 

    	 	- 11 -	Orion - Ninth Amendment to the Credit Agreement

     

    

for the Exchanged Term Loans taking place on a day other than the last day of the applicable
Interest Period for its Existing Term Loans.

subject to applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and to general principles of
equity and principles of good faith and fair dealing.

(c)

but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this
Amendment by facsimile or by email as a “.pdf” or “.tif” attachment shall be effective as delivery of a manually
executed counterpart of this Amendment. The words “execution,” “signed,” “signature,” and words of
like import in this Amendment shall be deemed to include electronic signatures or the keeping of records in electronic form, each of
which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping
system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global
and 

    	 	- 15 -	Orion - Ninth Amendment to the Credit Agreement

(c)
To the extent permitted by law, any provision of this Amendment or the Amended Credit Agreement held to be invalid, illegal or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without
affecting the validity, legality and enforceability of the remaining provisions thereof; and the invalidity of a particular provision
in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

(d)
To the extent required to take a position for U.S. federal income tax purposes, the parties shall treat this Amendment as resulting in
a deemed exchange of the Exchanged Term Loans for purposes of Section 1001 of the Code and no party shall adopt a contrary position,
except as otherwise required by changes in applicable Requirements of Law or pursuant to the good faith resolution of a Tax contest.

(e)
Each of the parties hereto hereby agrees that Sections 10.10(b), 10.10(c), 10.10(d) and 10.11 of the Amended Credit Agreement are incorporated
by reference herein, mutatis mutandis, and shall have the same force and effect with respect to this Amendment as if originally

JOINDER

JOINDER,
dated as of September ___, 2021 (this “Joinder”), by and among the undersigned person (the “New Term Lender”),
Orion Engineered Carbons GmbH, a limited liability company (Gesellschaft mit beschränkter Haftung) organized under the laws
of Germany (the “Borrower Representative”) and Goldman Sachs Bank USA, in its capacity as administrative agent for
the Lenders (together with its successors and assigns in such capacity, the “Administrative Agent”).

 

RECITALS:

 

WHEREAS,
reference is hereby made to the Ninth Amendment to Credit Agreement dated as of September 30, 2021 (the “Ninth Amendment”),
by and among the Borrower Representative, the other Loan Parties referred to therein, the New Term Lenders referred to therein (whether
pursuant to the execution and delivery of a Lender Consent, a Joinder or counterparts to the Ninth Amendment, as applicable) and the
Administrative Agent, to the Credit Agreement, originally dated as of July 25, 2014, as amended on August 7, 2014, September 29, 2016,
May 5, 2017, May 31, 2017, November 2, 2017, May 3, 2018, October 29, 2018 and April 2, 2019 (as further amended, restated, supplemented
or otherwise modified prior to the date hereof, the “Credit Agreement”) by and among the Borrower Representative,
the other Loan Parties named therein, each Lender party thereto and the Administrative Agent. All capitalized terms used but not defined
herein shall have the meaning ascribed thereto in the Credit Agreement or the Ninth Amendment, as applicable.

 

WHEREAS,
pursuant to the terms of the Ninth Amendment, the Borrower Representative has established Refinancing Term Loans with Exchanging Term
Lenders, Increasing Term Lenders and/or Additional Term Lenders; and

 

WHEREAS,
subject to the terms and conditions of the Credit Agreement and the Ninth Amendment, Additional Term Lenders may become Lenders pursuant
to one or more Joinders.

 

NOW,
THEREFORE, in consideration of the premises and agreements, provisions and covenants herein contained, the parties hereto agree as follows:

 

The
New Term Lender hereby agrees to make Refinancing Term Loans denominated in Dollars and/or Euro (as applicable) in the amount notified
to such Additional Term Lender by the Administrative Agent, but not to exceed the amount set forth on its signature page hereto, pursuant
to and in accordance with the Credit Agreement and the Ninth Amendment. The Refinancing Term Loans provided pursuant to this Joinder
shall be subject to all of the terms in the Credit Agreement and the Ninth Amendment and to the conditions set forth in the Credit Agreement
and the Ninth Amendment, and shall be entitled to all the benefits afforded by the Credit Agreement and the other Loan Documents, and
shall, without limiting the foregoing, benefit equally and ratably from the Guarantees and security interests created by the Term Security
Documents. The New Term Lender, the Borrower Representative and the Administrative Agent acknowledge and agree that the Refinancing Term
Loans provided pursuant to this Joinder shall constitute Term Loans for all purposes of the Credit Agreement and the other applicable
Loan Documents.

 

By
executing and delivering this Joinder, the New Term Lender shall be deemed to confirm to and agree with the other parties hereto as follows:
(i) such New Term Lender is legally authorized to enter into this Joinder and the Credit Agreement; (ii) such New Term Lender confirms
that it has received a copy of this Joinder, the Ninth Amendment and the Credit Agreement, together with copies of the most 

    	 	 	 

     

    

recent financial
statements delivered pursuant to Section 5.01 of the Credit Agreement and such other documents and information as it has deemed appropriate
to make its own credit analysis and decision to enter into this Joinder, the Ninth Amendment and the Credit Agreement; (iii) such
New Term Lender will independently and without reliance upon the Administrative Agent or any other Lender and based on such documents
and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under
this Joinder, the Ninth Amendment and the Credit Agreement; (iv) such New Term Lender appoints and authorizes the Administrative Agent
to take such action as agent on its behalf and to exercise such powers under this Joinder, the Ninth Amendment and the Credit Agreement
and the other Loan Documents as are delegated to the Administrative Agent, respectively, by the terms hereof and thereof, together with
such powers as are reasonably incidental thereto; and (v) such New Term Lender agrees that it will perform in accordance with their terms
all the obligations which by the terms of this Joinder, the Ninth Amendment and the Credit Agreement are required to be performed by
it as an Additional Term Lender.

 

Upon
(i) the execution of a counterpart of this Joinder by the New Term Lender, the Administrative Agent and the Borrower Representative and
(ii) the delivery to the Administrative Agent of a fully executed counterpart (including by way of telecopy or other electronic transmission)
hereof, the New Term Lender shall become a Lender under the Credit Agreement, effective as of the Ninth Amendment Effective Date.

 

Delivered
herewith by the New Term Lender to the Administrative Agent are such forms, certificates or other evidence with respect to United States
federal income tax withholding matters as the New Term Lender may be required to deliver to the Administrative Agent pursuant to the
Credit Agreement.

 

This
Joinder may not be amended, modified or waived except by an instrument or instruments in writing signed and delivered on behalf of each
of the parties hereto.

 

This
Joinder is a “Loan Document.”

 

This
Joinder, the Credit Agreement and the other Loan Documents constitute the entire agreement among the parties with respect to the subject
matter hereof and thereof and supersede all other prior agreements and understandings, both written and verbal, among the parties or
any of them with respect to the subject matter hereof.

 

Each
of the parties to this Joinder hereby agrees that Section 10.11 of the Credit Agreement is incorporated by reference herein, mutatis
mutandis, and shall have the same force and effect with respect to this Joinder as if originally set forth herein.

 

THIS
JOINDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.

 

In
the event any one or more of the provisions contained in this Joinder should be held invalid, illegal or unenforceable in any respect,
the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or
impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of
itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace
the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that
of the invalid, illegal or unenforceable provisions.

 

This
Joinder may be executed in counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the
same agreement. Delivery of an executed signature 

    	 	 	 

     

    

page to this Joinder by facsimile or other electronic transmission shall be as effective
as delivery of a manually signed counterpart of this Joinder. The words “execution,” “signed,” “signature,”
and words of like import in this Joinder shall be deemed to include electronic signatures or the keeping of records in electronic form,
each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures
in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar applicable state
laws based on the Uniform Electronic Transactions Act.
