required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and

	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

  

 (b) Upon any partial prepayment of the Notes pursuant to Section 8.2 or 8.7 or the
purchase of any Notes pursuant to Section 8.5, the principal amount of each required prepayment of the Notes becoming due under this Section 8.1 on and after the date of such prepayment or purchase shall be reduced in the same proportion
as the aggregate unpaid principal amount of the Notes is reduced as a result of such prepayment or purchase. 
 Section 8.2.
Optional Prepayments with Make-Whole Amount. The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes, in an amount not less than 10% of the aggregate principal amount
then outstanding of the Notes to be prepaid in the case of a partial prepayment (or such lesser amount as shall be required to effect a partial prepayment resulting from an offer of prepayment pursuant to Section 10.6), at 100% of the principal
amount so prepaid, together with interest accrued thereon to the date of such prepayment, plus the Make-Whole Amount determined for the prepayment date with respect to such principal amount of each Note then
outstanding. The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 15 days and not more than 60 days prior to the date fixed for such prepayment unless the Company and the
Required Holders agree to another time period pursuant to Section 17. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each
Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior
Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such
prepayment, the Company shall deliver to each holder of Notes a certificate of a Senior Financial Officer specifying the calculation of each such Make-Whole Amount as of the specified prepayment date.

 Section 8.3. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes pursuant to

theretofore called for prepayment 
 Section 8.4. Maturity; Surrender, Etc. In the case of each prepayment of Notes
pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole
Amount as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal
amount of any Note.

 Section 8.5. Purchase of Notes. The Company will not and will not permit any of
its Subsidiaries to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or
(b) pursuant to a written offer to purchase any outstanding Notes made by the Company or a Subsidiary pro rata to the holders of the Notes upon the same terms and conditions. Any such offer shall provide each holder with sufficient information
to enable it to make an informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 50% of the aggregate principal amount of the Notes then outstanding accept such offer, the Company
shall promptly notify the remaining holders of Notes of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 5 Business
Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by the Company or any of its Subsidiaries pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this
Agreement and no Notes may be issued in substitution or exchange for any such Notes. 
 Section 8.6. Make-Whole Amount. 

“Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the
Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole
Amount, the following terms have the following meanings:  
 “Called Principal” means, with respect to any Note, the
principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.  

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining
Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the
same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.  

“Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the
yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1)
on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such
Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond
equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities
(1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the
applicable Note.  

  
 -20- 

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

  

 If such yields are not Reported or the yields Reported as of such time are not
ascertainable (including by way of interpolation), then “Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported,
for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication)
for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life,
such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury
constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.  

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such
Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a
360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. 

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal
and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on
which interest payments are due to be made under the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date
pursuant to Section 8.4 or Section 12.1. 
 “Settlement Date” means, with respect to the Called Principal of
any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.  

Section 8.7. Change in Control. (a) Notice of Change in Control or Control Event. The Company will, within 15 Business
Days after any Responsible Officer has knowledge of the occurrence of any Change in Control or Control Event, give written notice of such Change in Control or Control Event to each holder of Notes unless notice in respect of such Change in
Control (or the Change in Control contemplated by such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7. If a Change in Control has occurred, such notice shall contain and constitute an offer to prepay
all of the Notes as described in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (g) of this Section 8.7.

 (b) Condition to Company Action. The Company will not take any action that
consummates or finalizes a Change in Control unless (i) at least 15 Business Days prior to such action it shall have given to each holder of Notes written notice containing and constituting an offer to prepay Notes as described in subparagraph
(c) of this Section 8.7, accompanied by the certificate described in subparagraph (g) of this Section 8.7, and (ii) contemporaneously with such action, it prepays all Notes required to be prepaid in accordance with this
Section 8.7. 
 (c) Offer to Prepay Notes. The offer to prepay Notes contemplated by subparagraphs (a) and
(b) of this Section 8.7 shall be an offer to prepay, in accordance with and subject to this Section 8.7, all, but not less than all, the Notes held by each holder (in this case only, “holder” in respect of any Note
registered in the name of a nominee for a disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”). If such Proposed Prepayment Date is in connection with an
offer contemplated by subparagraph (a) of this Section 8.7, such date shall be not less than 20 days and not more than 30 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed
Prepayment Date shall be the 20th day after the date of such offer). 
 (d) Acceptance; Rejection. A holder of Notes may
accept or reject the offer to prepay made pursuant to this Section 8.7 by causing a written notice of such acceptance or rejection to be delivered to the Company at least 5 Business Days prior to the Proposed Prepayment Date. A failure by a
holder of Notes to respond to an offer to prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such holder. 

(e) Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the unpaid principal
amount of such Notes, together with interest on such Notes accrued to the date of prepayment but without any premium or Make Whole Amount (the “Repurchase Price”). The prepayment shall be made on the Proposed Prepayment Date except

 SECTION 12. REMEDIES ON DEFAULT,
ETC. 
 Section 12.1. Acceleration. (a) If an Event of Default with respect to the Company described in
paragraph (h) or (i) of Section 11 (other than an Event of Default described in clause (i) of paragraph (h) or described in clause (vi) of paragraph (h) by virtue of the fact that such clause encompasses clause
(i) of paragraph (h)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable. 
 (b)
If any other Event of Default has occurred and is continuing, any holder or holders of more than 50% in aggregate principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company,
declare all the Notes then outstanding to be immediately due and payable. 
 (c) If any Event of Default described in paragraph (a) or
(b) of Section 11 has occurred and is continuing with respect to any Notes, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the
Company, declare all the Notes held by such holder or holders to be immediately due and payable. 
 Upon any Note’s becoming due and
payable under this Section 12.1, whether automatically or by declaration, such Note will forthwith mature and the entire unpaid principal amount of such Note, plus (i) all accrued and unpaid interest thereon (including, but not limited to,
interest accrued thereon at the Default Rate) and (ii) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case
without presentment, demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by
the Company (except as herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide
compensation for the deprivation of such right under such circumstances. 
 Section 12.2. Other Remedies. If any Default or
Event of Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and
enforce the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note or Subsidiary Guaranty, or for an injunction against a
violation of any of the terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 

Section 12.3. Rescission. At any time after the Notes have been declared due and payable pursuant to clause (b) or
(c) of Section 12.1, the holders of more than 50% in aggregate principal amount of the Notes then outstanding, by written notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has
paid all overdue interest on the Notes, all principal of and Make-Whole Amount on any Notes that are due and payable and are unpaid other than by reason of such declaration, and all interest on such overdue principal and

  
 -35- 

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

  

 
Make-Whole Amount and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor any other Person shall have
paid any amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been
waived pursuant to Section 17, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to any Notes. No rescission and annulment under this Section 12.3 will extend to or affect any
subsequent Event of Default or Default or impair any right consequent thereon. 
 Section 12.4. No Waivers or Election of Remedies,
Expenses, Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right,
power or remedy conferred by this Agreement, any Subsidiary Guaranty or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by
statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred
in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements. 

SECTION 13. REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES. 

Section 13.1. Registration of Notes. The Company shall keep at its principal executive office a register for the registration and
registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. If any holder of one or more
Notes is a nominee, then (a) the name and address of the beneficial owner of such Note or Notes shall also be registered in such register as an owner and holder thereof and (b) at any such beneficial owner’s option, either such
beneficial owner or its nominee may execute any amendment, waiver or consent pursuant to this Agreement. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the
owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to any holder of a Note that is an Institutional Investor promptly upon request therefor, a
complete and correct copy of the names and addresses of all registered holders of Notes. 
 Section 13.2. Transfer and
Exchange of Notes. Upon surrender of any Note to the Company at the address and to the attention of the designated officer (all as specified in Section 18(iii)), for registration of transfer or exchange (and in the case of a surrender for
registration of transfer accompanied by a written instrument of transfer duly executed by the registered holder of such Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other
information for notices of each transferee of such Note or part thereof), within ten Business Days thereafter, the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by
the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request

  
 -36- 

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

  

 
and shall be substantially in the form of the Note originally issued hereunder. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the
surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of
Notes. Notes shall not be transferred in denominations of less than $100,000, provided that if necessary to enable the registration of transfer by a holder of its entire holding of Notes, one Note may be in a denomination of less than
$100,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.3, provided, that in lieu thereof such holder may
(in reliance upon information provided by the Company, which shall not be unreasonably withheld) make a representation to the effect that the purchase by any holder of any Note will not constitute a non-exempt prohibited transaction under section
406(a) of ERISA. 
 The Notes have not been registered under the Securities Act or under the securities laws of any state and may not
be transferred or resold unless registered under the Securities Act and all applicable state securities laws or unless an exemption from the requirement for such registration is available. 

Section 13.3. Replacement of Notes. Upon receipt by the Company at the address and to the attention of the designated officer (all
as specified in Section 18(iii)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such
Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and 
 (a) in the
case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least
$50,000,000 or a Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or 

(b) in the case of mutilation, upon surrender and cancellation thereof, 

the Company at its own expense shall execute and deliver not more than ten Business Days following satisfaction of such conditions, in lieu thereof, a new
Note dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

 Section 13.4 Prohibition on Transfer to a Competitor. Each Purchaser agrees that, prior to the existence of a Default
or Event of Default, it will not sell, assign or otherwise transfer any Note or portion thereof to a Competitor or Competitor Affiliate. As used herein “Competitor” means any Person which is primarily engaged in the lines of business of
the Company and its Restricted Subsidiaries as described in the Memorandum or as changed from time to time. “Competitor
Affiliate” means, with respect to any Competitor, (a) any Person at the time directly or indirectly controlling, controlled by or under common control with such Competitor, (b) any

  
 -37- 

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

  

 
other Person of which such Competitor at the time owns 50% or more on a consolidated basis of the equity interest of such Person, and (c) any other Person which at the time owns 50% or
more of any class of the capital stock or other equity interest of such Competitor, provided that: (i) the provision of investment advisory services by a Person to an employee benefit plan which is owned or controlled by a Person which would
otherwise be a Competitor or Competitor Affiliate shall not of itself cause the Person providing such services to be deemed a Competitor or Competitor Affiliate; and (ii) in no event shall an Institutional Investor be deemed a Competitor or
Competitor Affiliate. 
 SECTION 14. PAYMENTS ON NOTES. 

Section 14.1. Place of Payment. Subject to Section 14.2, payments of principal,
Make-Whole Amount and interest becoming due and payable on the Notes shall be made in New York, New York at the principal office of Bank of America, N.A. in such jurisdiction. The Company may at any time, by

jurisdiction. 
 Section 14.2. Home Office Payment. So long as any Purchaser or its nominee shall be the
holder of any Note, and notwithstanding anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, interest and all other amounts
becoming due hereunder by the method and at the address specified for such purpose below such Purchaser’s name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the
Company in writing for such purpose, without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment
in full of any Note, such Purchaser shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant
to Section 14.1. Prior to any sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, either endorse thereon the amount of principal paid thereon and the last date to which interest has
been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect
transferee of any Note purchased by a Purchaser under this Agreement and that has made the same agreement relating to such Note as the Purchasers have made in this Section 14.2.

Section 15.2. Survival. The obligations of the Company under this Section 15 will survive the payment or transfer of any
Note, the enforcement, amendment or waiver of any provision of this Agreement, any Subsidiary Guaranty or the Notes, and the termination of this Agreement.

 All representations and warranties contained herein shall survive the execution and
delivery of this Agreement and the Notes, the purchase or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any
investigation made at any time by or on behalf of such Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement shall be deemed
representations and warranties of the Company under this Agreement. Subject to the preceding sentence, this Agreement, the Notes and any Subsidiary Guaranties embody the entire agreement and understanding between each Purchaser and the Company and
supersede all prior agreements and understandings relating to the subject matter hereof. 
 SECTION 17. AMENDMENT

observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), only with the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of Sections 1, 2, 3, 4, 5,

 Section 17.2. Solicitation of Holders of Notes. 

(a) Solicitation. The Company will provide each holder of a Note with sufficient information, sufficiently far in advance of the
date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes or any Subsidiary Guaranty.
The Company will deliver executed or true and correct copies of each amendment, waiver or consent effected pursuant to this Section 17 or any Subsidiary Guaranty to each holder of a Note promptly following the date on which it is executed and
delivered by, or receives the consent or approval of, the requisite holders of Notes. 
 (b) Payment. The Company will
not directly or indirectly pay or cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of a Note as consideration for or as
an inducement to the entering into by such holder of any waiver or amendment of any of the terms and provisions hereof or of any Subsidiary Guaranty or any Note unless such remuneration is concurrently paid, or security is concurrently granted or
other credit support concurrently provided, on the same terms, ratably to each holder of a Note even if such holder did not consent to such waiver or amendment.

 Section 17.3. Binding Effect,
etc. Any amendment or waiver consented to as provided in this Section 17 or any Subsidiary Guaranty applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without

right consequent thereon. No course of dealing between the Company and any holder of a Note and no delay in exercising any rights hereunder or under any Note or Subsidiary Guaranty shall operate as a waiver of any rights of any holder of such Note.

percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement, any Subsidiary Guaranty or the Notes, or have directed the taking of any action
provided herein or in any Subsidiary Guaranty or the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any

 SECTION 20. CONFIDENTIAL INFORMATION. 

For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by or
on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when

in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to
(i) its directors, officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its auditors, financial advisors
and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or

which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection
with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under such Purchaser’s Notes, this Agreement or any Subsidiary Guaranty. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be
entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under
this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying this Section 20.  

In the event that as a condition to receiving access to information relating to the Company or its Subsidiaries in connection with the
transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or
otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any such other confidentiality
undertaking.

Purchaser’s Affiliates (a “Substitute Purchaser”) as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Substitute
Purchaser, shall contain such Substitute Purchaser’s agreement to be bound by this Agreement and shall contain a confirmation by such Substitute Purchaser of the accuracy with respect to it of the representations set forth in Section 6.
Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Substitute Purchaser in lieu of such original Purchaser. In the event that such Substitute
Purchaser is so substituted as a Purchaser hereunder and such Substitute Purchaser thereafter transfers to such original Purchaser all of the Notes then held by such Substitute Purchaser, upon receipt by the Company of notice of such transfer, any
reference to such Substitute Purchaser as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Substitute Purchaser, but shall refer to such original Purchaser, and such original
Purchaser shall again have all the rights of an original holder of the Notes under this Agreement.  
 SECTION 22.
MISCELLANEOUS. 
 Section 22.1. Successors and Assigns. All covenants and other agreements contained in this
Agreement by or on behalf of any of the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. 

Section 22.2. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but
without limiting the requirement in Section 8.4 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a
date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any
Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding
Business Day. 
 Section 22.3. Accounting Terms. (a) All accounting terms used herein which are not expressly
defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and
(ii) all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with this Agreement (including, without limitation, Section 9, Section 10 and the definition of “Debt”), any
election by the Company to measure any financial liability using fair value (as permitted by

Financial Accounting Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair
Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been
made. 
 (b) Notwithstanding the foregoing provisions of Section 22.2(a), if at any time any change in GAAP would require a
lessee to capitalize its operating leases under GAAP on the balance sheet of such lessee, the GAAP treatment of operating leases on the date of the Closing shall continue to apply for purposes of this Agreement and the calculation of the financial
covenants under this Agreement. 
 Section 22.4. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. 

Section 22.5. Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being
independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action
to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. 

For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be deemed to be a part hereof. 

Section 22.6. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original but
all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto. 

Section 22.7. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties
shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State. 

Section 22.8. Jurisdiction and Process; Waiver of Jury Trial. (a) The Company irrevocably submits to the non-exclusive
jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to this Agreement or the Notes. To the fullest extent permitted by
applicable law, the Company irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

 (b) The Company consents to process being served by or on behalf of any holder of Notes in
any suit, action or proceeding of the nature referred to in Section 22.8(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to it at its address
specified in Section 18 or at such other address of which such holder shall then have been notified pursuant to said Section. The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of
process upon it in any such suit, action or proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively
presumed received as evidenced by a delivery receipt furnished by the United States Postal Service or any reputable commercial delivery service. 

(c) Nothing in this Section 22.8 shall affect the right of any holder of a Note to serve process in any manner permitted by law, or limit
any right that the holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. 

(d) THE PARTIES HERETO HEREBY WAIVE TRIAL

(to Note Purchase Agreement) 

 FORM OF OPINION OF
GENERAL COUNSEL 
 TO THE COMPANY 

The closing opinion of H. Edward Wynn, Esq., General Counsel of the Company, which is called for by Section 4.4 of the Note Purchase
Agreement, shall be dated the Closing Date and addressed to the Purchasers, shall be satisfactory in scope and form to each Purchaser and shall be to the effect that: 

1. The Company has the corporate power and authority to own, pledge and operate its properties, to lease any properties it operates under
lease, to conduct its business as presently conducted and to execute and deliver the Note Agreement and the Notes and to perform its respective obligations thereunder. 

2. Assuming the proceeds of the Notes are used solely for the purposes set forth in the Note Agreement, neither the execution and delivery by
the Company of the Note Agreement, nor the issue and sale of the Notes, nor the performance by the Company of its respective obligations thereunder: (i) results in the breach of, or constitutes a default under, any material indenture, mortgage,
deed of trust, lease or sublease agreement to which the Company is a party or by which it or any of its properties is bound; (ii) results in the creation or imposition of any lien upon any of the property of the Company under any indenture,
mortgage or other agreement described in clause (i) above; or (iii) requires the consent or approval of, or any filing or registration with, any governmental body, agency or authority other than those which have been obtained. 

3. There are no actions, suits, or proceedings pending or, to the knowledge of such counsel after due inquiry, threatened against the Company
or any of its assets and properties that questions or may affect the validity of any action to be taken by the Company pursuant to the Note Agreement or the Notes, or that seeks to restrain the Company from carrying out the transactions contemplated
therein or the Company’s obligations thereunder.

(to Note Purchase Agreement) 

 FORM OF OPINION OF
SPECIAL COUNSEL 
 TO THE COMPANY 

The closing opinion of Jones Day, special counsel to the Company, which is called for by Section 4.4 of the Note Purchase Agreement,
shall be dated the Closing Date and addressed to the Purchasers, shall be satisfactory in scope and form to each Purchaser and shall be to the effect that: 

1. The Company is a corporation validly existing and in good standing under the laws of Delaware. The Company is duly qualified and in good
standing as a foreign corporation authorized to do business in Illinois. 
 2. The issuance and sale of the Notes and the execution, delivery
and performance of the Note Agreement and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and the Note Agreement and the Notes have been executed and delivered and constitute the valid and binding
obligation of the Company enforceable against the Company in accordance with their respective terms. 
 3. Assuming the proceeds of the Notes
are used solely for the purposes set forth in the Note Agreement, neither the execution and delivery by the Company of the Note Agreement or the Notes, nor the performance by the Company of its obligations thereunder: (i) violates any provision
of the Company’s certificate of incorporation or bylaws; or (ii) violates any law or regulation (including any applicable order or decree of any court or governmental instrumentality known to us) applicable to the Company which in our
experience is typically applicable to transactions of the type contemplated by the Note Agreement (except we express no opinion as to any law which might be violated by any misrepresentation or omission or a fraudulent act). 

4. The Company is not an “investment company” registered or required to be registered under the Investment Company Act of 1940, as
amended, or, to our knowledge, controlled by such a company. 
 5. Assuming the offer, issue, sale and delivery of the Notes occurs in the
manner and under the circumstances contemplated by the Note Agreement, the issuance and sale of the Notes do not, under existing law, require the registration of the Notes under the Securities Act of 1933, as amended. 

6. The issuance of the Notes and the use of the proceeds of sale of the Notes in accordance with the provisions of, and as contemplated by, the
Note Agreement (including the representations and warranties set forth in the Note Agreement) do not violate or conflict with Regulations T, U or X of the Board of Governors of the Federal Reserve System 

The opinion of Jones Day, shall cover such other matters relating to the sale of the Notes as each Purchaser may reasonably request and
successors and assigns of the Purchasers shall be entitled to rely on such opinion. With respect to matters of fact on which such opinion is based, such counsel shall be entitled to rely on appropriate certificates of public officials and other
officers of the Company.

SECTION 5. REPRESENTATIONS AND WARRANTIES OF THE
COMPANY. 
 The Company represents and warrants to each Purchaser that: 

Section 5.1. Organization; Power and Authority. The Company is a corporation duly organized, validly existing and in good standing
under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure
to be so qualified or in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has the corporate power and authority to own or hold under lease the properties it purports to
own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof. 

Section 5.2. Authorization, Etc. This Agreement and the Notes have been duly authorized by all necessary corporate action on the
part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each such Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as
such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless
of whether such enforceability is considered in a proceeding in equity or at law). 
 Section 5.3. Disclosure. The Company,
through its agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated, has delivered to you and each other Purchaser a copy of a Private Placement Memorandum, dated April, 2015 (the “Memorandum”), relating to the
transactions contemplated hereby. The Memorandum fairly describes, in all material respects, the general nature of the business and principal properties of the Company and its Restricted Subsidiaries. This Agreement, the Memorandum, the documents,
certificates or other writings delivered to the Purchasers by or on behalf of the Company in connection with the transactions contemplated hereby, the financial statements listed in Schedule 5.5 and the Company’s Forms 10-K and 10-Q heretofore
filed with the Securities and Exchange Commission, in each case, delivered to the Purchasers (or deemed to be delivered to the Purchasers in the case of the Company’s Forms 10-K and 10-Q) prior to May 8, 2015 (this Agreement, the
Memorandum and such documents, certificates or other writings and such financial statements being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not contain any untrue statement of a material fact or
omit to state any material fact necessary to make the statements therein not misleading in light of the circumstances under which they were made. Except as disclosed in the Disclosure Documents, since December 31, 2014, there has been no change
in the financial condition, operations, business or properties of the Company or any of its Restricted Subsidiaries except changes that individually or in the aggregate would not reasonably be expected to have a Material Adverse Effect. There is no
fact known to the Company that would reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Disclosure Documents. 

Section 5.4. Organization and Ownership of Shares of Subsidiaries; Affiliates. (a) Schedule 5.4 contains (except as
noted therein) complete and correct lists (i) of the Company’s Restricted and Unrestricted Subsidiaries, showing, as to each Subsidiary, the correct name thereof, the jurisdiction of its organization, and the percentage of shares of each
class of its capital stock or similar equity interests outstanding owned by the Company and each other Subsidiary, (ii) of the Company’s Affiliates, other than Subsidiaries, and (iii) of the Company’s directors and senior officers.

	STEPAN COMPANY	  		  	NOTE PURCHASE AGREEMENT

  

(b) All of the outstanding shares of capital stock or similar equity interests of each Subsidiary shown in Schedule 5.4 as being owned by the
Company and its Subsidiaries have been validly issued, are fully paid and nonassessable and are owned by the Company or another Subsidiary free and clear of any Lien (except as otherwise disclosed in Schedule 5.4). 

(c) Each Subsidiary identified in Schedule 5.4 is a corporation or other legal entity duly organized, validly existing and in good standing
under the laws of its jurisdiction of organization, and is duly qualified as a foreign corporation or other legal entity and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as
to which the failure to be so qualified or in good standing would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Each such Subsidiary has the corporate or other power and authority to own or hold
under lease the properties it purports to own or hold under lease and to transact the business it transacts and proposes to transact. 
 (d)
No Subsidiary is a party to, or otherwise subject to, any legal, regulatory or contractual restriction (other than this Agreement, the agreements listed on Schedule 5.4 and customary limitations imposed by corporate law or similar statutes)
restricting the ability of such Subsidiary to pay dividends out of profits or make any other similar distributions of profits to the Company or any of its Subsidiaries that owns outstanding shares of capital stock or similar equity interests of such
Subsidiary. 
 Section 5.5. Financial Statements; Material Liabilities. The Company has delivered to each Purchaser
copies of the financial statements of the Company and its Subsidiaries listed on Schedule 5.5. All of said financial statements (including in each case the related schedules and notes) fairly present in all material respects the consolidated
financial position of the Company and its Subsidiaries as of the respective dates specified in such Schedule and the consolidated results of their operations and cash flows for the respective periods so specified and have been prepared in accordance
with GAAP consistently applied throughout the periods involved except (a) as set forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments), and (b) as specifically disclosed in
writing by the Company in its public filings with the Securities and Exchange Commission. The Company and its Subsidiaries do not have any Material liabilities that are not disclosed on such financial statements or otherwise disclosed in the
Disclosure Documents. 
 Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution, delivery and
performance by the Company of this Agreement and the Notes will not (a) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company or any Subsidiary under,
any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, shareholders agreement (if any) or any other agreement or instrument to which the Company or any Subsidiary is bound or by which the
Company or any Subsidiary or any of their respective properties may be bound or affected, (b) conflict with or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator
or Governmental Authority applicable to the Company or any Subsidiary, or (c) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Company or any Subsidiary.

	STEPAN COMPANY	  		  	NOTE PURCHASE AGREEMENT

  

Section 5.7. Governmental Authorizations, Etc. No consent, approval or authorization of, or registration, filing or
declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by the Company of this Agreement or the Notes. 

Section 5.8. Litigation; Observance of Agreements, Statutes and Orders. (a) There are no actions, suits,
investigations or proceedings pending or, to the knowledge of the Company, threatened against or affecting the Company or any Restricted Subsidiary or any property of the Company or any Restricted Subsidiary in any court or before any arbitrator of
any kind or before or by any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. 

(b) Neither the Company nor any Restricted Subsidiary is (i) in default under any agreement or instrument to which it is a party or by
which it is bound, (ii) in violation of any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority or (iii) in violation of any applicable law, ordinance, rule or regulation of any Governmental Authority
(including, without limitation, Environmental Laws, the USA PATRIOT Act or any of the other laws and regulations that are referred to in Section 5.16), which default or violation could, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect. 
 Section 5.9. Taxes. The Company and its Subsidiaries have filed all tax returns
that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such
taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (a) the amount of which is not individually or in the aggregate Material or (b) the amount, applicability or
validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The Company knows of no
basis for any other tax or assessment that would reasonably be expected to have a Material Adverse Effect. The charges, accruals and reserves on the books of the Company and its Subsidiaries in respect of federal, state or other taxes for all fiscal
periods are adequate. The federal income tax liabilities of the Company and its Subsidiaries have been finally determined (whether by reason of completed audits or the statute of limitations having run) for all fiscal years up to and including the
fiscal year ended December 31, 2010. 
 Section 5.10. Title to Property; Leases. The Company and its Restricted
Subsidiaries have good and sufficient title, leasehold or other interest to their respective properties which the Company and its Restricted Subsidiaries own or purport to own that individually or in the aggregate are Material, including all such
properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to have been acquired by the Company or any Restricted Subsidiary after said date (except as sold or otherwise disposed of in the ordinary
course of business), in each case free and clear of Liens prohibited by this Agreement. All leases that individually or in the aggregate are Material are valid and subsisting and are in full force and effect in all material respects.

	STEPAN COMPANY	  		  	NOTE PURCHASE AGREEMENT

  

Section 5.11. Licenses, Permits, Etc. Except as disclosed in Schedule 5.11, 

(a) the Company and its Restricted Subsidiaries own or possess all licenses, permits, franchises, authorizations, patents,
copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, that individually or in the aggregate are Material, without known conflict with the rights of others; 

(b) to the best knowledge of the Company, no product of the Company or any of its Restricted Subsidiaries infringes in any
Material respect any license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person, except for any such infringement which would not reasonably be
expected to have a Material Adverse Effect; and 
 (c) to the best knowledge of the Company, there is no Material violation
by any Person of any right of the Company or any of its Restricted Subsidiaries with respect to any patent, copyright, proprietary software, service mark, trademark, trade name or other right owned or used by the Company or any of its Restricted
Subsidiaries, except violations which would not reasonably be expected to have a Material Adverse Effect. 
 Section 5.12.
Compliance with ERISA. (a) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and would not
reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit
plans (as defined in section 3 of ERISA), and no event, transaction or condition has occurred or exists that would reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition
of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to section 430(k) of the Code or to any such penalty or excise tax provisions under the Code or
federal law or section 4068 of ERISA or by the granting of a security interest in connection with the amendment of a Plan, other than such liabilities or Liens as would not be individually or in the aggregate reasonably likely to have a Material
Adverse Effect. 
 (b) The Unfunded Liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such
Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation report, did not exceed $10,000,000 in the aggregate for all Plans. 

(c) The Company and its ERISA Affiliates have not incurred any Unfunded Liabilities in respect of Multiemployer Plans that individually or in
the aggregate are Material. 
 (d) The expected postretirement benefit obligation (determined as of the last day of the Company’s most
recently ended fiscal year in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 715-60, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the
Company and its Subsidiaries is not Material.

	STEPAN COMPANY	  		  	NOTE PURCHASE AGREEMENT

  

(e) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is
subject to the prohibitions of section 406 of ERISA or in connection with which a tax would be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Company to each Purchaser in
the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of such Purchaser’s representation in Section 6.3 as to the sources of the funds to be used to pay the purchase price of the Notes to be
purchased by such Purchaser. 
 Section 5.13. Private Offering by the Company. Neither the Company nor anyone acting on its
behalf has offered the Notes or any similar Securities for sale to, or solicited any offer to buy the Notes or any similar Securities from, or otherwise approached or negotiated in respect thereof with, any Person other than the Purchasers and not
more than 35 other Institutional Investors, each of which has been offered the Notes at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of
the Notes to the registration requirements of section 5 of the Securities Act or to the registration requirements of any Securities or blue sky laws of any applicable jurisdiction. 

Section 5.14. Use of Proceeds; Margin Regulations. The Company will apply the proceeds of the sale of the Notes to
refinance existing Debt and for general corporate purposes of the Company. No part of the proceeds from the sale of the Notes hereunder will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning
of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Company in a violation of Regulation X of said
Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 5% of the value of the consolidated assets of the Company and its Subsidiaries and the
Company does not have any present intention that margin stock will constitute more than 5% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall
have the meanings assigned to them in said Regulation U.

“Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the
Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole
Amount, the following terms have the following meanings: 
 “Called Principal” means, with respect to any Note, the
principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining
Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the
same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. 

“Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the
yield(s) reported as of 10:00 a.m. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1)
on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.
If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in
accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and
greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.

	STEPAN COMPANY	  		  	NOTE PURCHASE AGREEMENT

  

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then
“Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so
reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term
equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by
interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and
less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note.  

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing (i) such
Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a
360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. 

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal
and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on
which interest payments are due to be made under the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date
pursuant to Section 8.2 or Section 12.1. 
 “Settlement Date” means, with respect to the Called Principal of
any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

Section 8.7. Change in Control. (a) Notice of Change in Control or Control Event. The Company will, within 15 Business
Days after any Responsible Officer has knowledge of the occurrence of any Change in Control or Control Event, give written notice of such Change in Control or Control Event to each holder of Notes unless notice in respect of such Change in Control
(or the Change in Control contemplated by such Control Event) shall have been given pursuant to subparagraph (b) of this Section 8.7. If a Change in Control has occurred, such notice shall contain and constitute an offer to prepay all of
the Notes as described in subparagraph (c) of this Section 8.7 and shall be accompanied by the certificate described in subparagraph (g) of this Section 8.7.

disclosed beneficial owner shall mean such beneficial owner) on a date specified in such offer (the “Proposed Prepayment Date”). If such Proposed Prepayment Date is in connection with an offer contemplated by subparagraph
(a) of this Section 8.7, such date shall be not less than 20 days and not more than 30 days after the date of such offer (if the Proposed Prepayment Date shall not be specified in such offer, the Proposed Prepayment Date shall be the 20th
day after the date of such offer). 
 (d) Acceptance; Rejection. A holder of Notes may accept or reject the offer to prepay made
pursuant to this Section 8.7 by causing a written notice of such acceptance or rejection to be delivered to the Company at least 5 Business Days prior to the Proposed Prepayment Date. A failure by a holder of Notes to respond to an offer to
prepay made pursuant to this Section 8.7 shall be deemed to constitute a rejection of such offer by such holder. 
 (e)
Prepayment. Prepayment of the Notes to be prepaid pursuant to this Section 8.7 shall be at 100% of the unpaid principal amount of such Notes, together with interest on such Notes accrued to the date of prepayment but without any premium

(f) Deferral Pending Change in Control. The obligation of the Company to prepay Notes pursuant to the offers required by subparagraph
(b) and accepted in accordance with subparagraph (d) of this Section 8.7 is subject to the occurrence of the Change in Control in respect of which such offers and acceptances shall have been made. In the event that such Change in
Control does not occur on the Proposed Prepayment Date in respect thereof, the prepayment shall be deferred until and shall be made on the date on which such Change in Control occurs. The Company shall keep each holder of Notes reasonably and timely
informed of (i) any such deferral of the date of prepayment, (ii) the date on which such Change in Control and the prepayment are expected to occur, and (iii) any determination by the Company that efforts to effect such Change in
Control have ceased or been abandoned (in which case the offers and acceptances made pursuant to this Section 8.7 in respect of such Change in Control shall be deemed rescinded).

outstanding immediately prior to such payment.

respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are maintained with respect thereto) as is
customary in the case of entities of established reputations engaged in the same or a similar business and similarly situated except for any non-maintenance that would not reasonably be expected to have a Material Adverse Effect.

SECTION 12. REMEDIES ON DEFAULT, ETC.

(i) of Section 11 (other than an Event of Default described in clause (i) of paragraph (h) or described in clause (vi) of paragraph (h) by virtue of the fact that such clause encompasses clause (i) of paragraph
(h)) has occurred, all the Notes then outstanding shall automatically become immediately due and payable. 
 (b) If any other Event of
Default has occurred and is continuing, any holder or holders of more than 50% in aggregate principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all the Notes then
outstanding to be immediately due and payable. 
 (c) If any Event of Default described in paragraph (a) or (b) of Section 11
has occurred and is continuing with respect to any Notes, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes
held by such holder or holders to be immediately due and payable. 
 Upon any Note’s becoming due and payable under this
Section 12.1, whether automatically or by declaration, such Note will forthwith mature and the entire unpaid principal amount of such Note, plus (i) all accrued and unpaid interest thereon (including, but not limited to, interest accrued
thereon at the Default Rate) and (ii) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment,
demand, protest or further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as
herein specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the
deprivation of such right under such circumstances. 
 Section 12.2. Other Remedies. If any Default or Event of Default
has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce the rights

terms hereof or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 
 Section 12.3.

notice to the Company, may rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount on any Notes that are due and payable and are unpaid
other than by reason of such declaration, and all interest on such overdue principal and

paid any amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due solely by reason of such declaration, have been cured or have been
waived pursuant to Section 17, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to any Notes. No rescission and annulment under this Section 12.3 will extend to or affect any
subsequent Event of Default or Default or impair any right consequent thereon. 
 Section 12.4. No Waivers or Election of Remedies,
Expenses, Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right,
power or remedy conferred by this Agreement, any Subsidiary Guaranty or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to herein or therein or now or hereafter available at law, in equity, by
statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall be sufficient to cover all costs and expenses of such holder incurred

$100,000. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representation set forth in Section 6.3, provided, that in lieu thereof such holder may (in
reliance upon information provided by the Company, which shall not be unreasonably withheld) make a representation to the effect that the purchase by any holder of any Note will not constitute a non-exempt prohibited transaction under section 406(a)
of ERISA.

transferred or resold unless registered under the Securities Act and all applicable state securities laws or unless an exemption from the requirement for such registration is available.

Qualified Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or

the Company at its own expense shall execute and deliver not more than ten Business Days following satisfaction of such conditions, in lieu thereof, a new
Note dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

of any class of the capital stock or other equity interest of such Competitor, provided that: (i) the provision of investment advisory services by a Person to an employee benefit plan which is owned or controlled by a Person which would
otherwise be a Competitor or Competitor Affiliate shall not of itself cause the Person providing such services to be deemed a Competitor or Competitor Affiliate; and (ii) in no event shall an Institutional Investor be deemed a Competitor or
Competitor Affiliate.

effected or waivers granted or to be effected or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Notes that were acquired under the same or similar conditions)
shall be void and of no force or effect except solely as to such holder. 
 Section 17.3. Binding Effect, etc. Any amendment or
waiver consented to as provided in this Section 17 or any Subsidiary Guaranty applies equally to all holders of Notes and is binding upon them and upon each future holder of any Note and upon the Company without regard to whether such Note has
been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course
of dealing between the Company and any holder of a Note and no delay in exercising any rights hereunder or under any Note or Subsidiary Guaranty shall operate as a waiver of any rights of any holder of such Note. 

Section 17.4. Notes Held by Company, etc. Solely for the purpose of determining whether the holders of the requisite percentage of
the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this Agreement, any Subsidiary Guaranty or the Notes, or have directed the taking of any action provided herein or
in any Subsidiary Guaranty or the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or indirectly owned by the Company or any of its Affiliates
shall be deemed not to be outstanding.

 SECTION 19. REPRODUCTION

 This Agreement and all documents relating thereto, including, without limitation,
(a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any Purchaser at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously
or hereafter furnished to any Purchaser, may be reproduced by such Purchaser by any photographic, photostatic, electronic, digital, or other similar process and such Purchaser may destroy any original document so reproduced. The Company agrees and
stipulates that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not
such reproduction was made by such Purchaser in the regular course of business) and any enlargement, facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company
or any other holder of Notes from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction.

SECTION 20. CONFIDENTIAL INFORMATION. 

For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by
or on behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when
received by such Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the
time of such disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure
by the Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information
in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to
(i) its directors, officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its auditors, financial advisors
and other professional advisors who agree to hold confidential the Confidential Information substantially in accordance with this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or
offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by this Section 20), (v) any Person from which it offers to
purchase any Security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by this Section 20), (vi) any federal or state regulatory authority having jurisdiction over such
Purchaser, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment portfolio, or (viii) any other Person to
which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena or other legal process, (y) in connection
with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and disclosure to be necessary or appropriate in the
enforcement or for the protection of the rights and remedies under such Purchaser’s Notes, this Agreement or any Subsidiary Guaranty. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to be bound by and to be
entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered to such holder under
this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying this Section 20.  

In the event that as a condition to receiving access to information relating to the Company or its Subsidiaries in connection with the
transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser or holder of a Note is required to agree to a confidentiality undertaking (whether through IntraLinks, another secure website, a secure virtual workspace or
otherwise) which is different from this Section 20, this Section 20 shall not be amended thereby and, as between such Purchaser or such holder and the Company, this Section 20 shall supersede any such other confidentiality
undertaking.

SECTION 21. SUBSTITUTION OF PURCHASER. 

Each Purchaser shall have the right to substitute any one of its Affiliates or another Purchaser or any one of such other Purchaser’s Affiliates (a
“Substitute Purchaser”) as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be signed by both such Purchaser and such Substitute Purchaser, shall contain such
Substitute Purchaser’s agreement to be bound by this Agreement and shall contain a confirmation by such Substitute Purchaser of the accuracy with respect to it of the representations set forth in Section 6. Upon receipt of such notice, any
reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Substitute Purchaser in lieu of such original Purchaser. In the event that such Substitute Purchaser is so substituted as a
Purchaser hereunder and such Substitute Purchaser thereafter transfers to such original Purchaser all of the Notes then held by such Substitute Purchaser, upon receipt by the Company of notice of such transfer, any reference to such Substitute
Purchaser as a “Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Substitute Purchaser, but shall refer to such original Purchaser, and such original Purchaser shall again have
all the rights of an original holder of the Notes under this Agreement. 
 SECTION 22. MISCELLANEOUS. 

Section 22.1. Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of the
parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. 

Section 22.2. Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but
without limiting the requirement in Section 8.2 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a
date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date of any
Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next succeeding
Business Day. 
 Section 22.3. Accounting Terms. (a) All accounting terms used herein which are not expressly
defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and
(ii) all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with this Agreement (including, without limitation, Section 9, Section 10 and the definition of “Debt”), any
election by the Company to measure any financial liability using fair value (as permitted by 

  
 -43- 

					
	STEPAN COMPANY	  		  	NOTE PURCHASE AGREEMENT

  

Financial Accounting Standards Board Accounting Standards Codification Topic No. 825-10-25 – Fair
Value Option, International Accounting Standard 39 – Financial Instruments: Recognition and Measurement or any similar accounting standard) shall be disregarded and such determination shall be made as if such election had not been
made. 
 (b) Notwithstanding the foregoing provisions of Section 22.2(a), if at any time any change in GAAP would require a lessee to
capitalize its operating leases under GAAP on the balance sheet of such lessee, the GAAP treatment of operating leases on the date of the Closing shall continue to apply for purposes of this Agreement and the calculation of the financial covenants
under this Agreement. 
 Section 22.4. Severability. Any provision of this Agreement that is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the
full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. 
 Section 22.5.
Construction. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express
contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action
is taken directly or indirectly by such Person. 
 For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall
be deemed to be a part hereof. 
 Section 22.6. Counterparts. This Agreement may be executed in any number of counterparts, each
of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto. 

Section 22.7. Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of the parties
shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State. 

Section 22.8. Jurisdiction and Process; Waiver of Jury Trial. (a) The Company irrevocably submits to the non-exclusive
jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York, over any suit, action or proceeding arising out of or relating to this Agreement or the Notes. To the fullest extent permitted by
applicable law, the Company irrevocably waives and agrees not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such court, any objection that it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

	STEPAN COMPANY	  		  	NOTE PURCHASE AGREEMENT

  

(b) The Company consents to process being served by or on behalf of any holder of Notes in any suit, action or proceeding of the nature
referred to in Section 22.8(a) by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, return receipt requested, to it at its address specified in Section 18 or at such other
address of which such holder shall then have been notified pursuant to said Section. The Company agrees that such service upon receipt (i) shall be deemed in every respect effective service of process upon it in any such suit, action or
proceeding and (ii) shall, to the fullest extent permitted by applicable law, be taken and held to be valid personal service upon and personal delivery to it. Notices hereunder shall be conclusively presumed received as evidenced by a delivery
receipt furnished by the United States Postal Service or any reputable commercial delivery service. 
 (c) Nothing in this Section 22.8
shall affect the right of any holder of a Note to serve process in any manner permitted by law, or limit any right that the holders of any of the Notes may have to bring proceedings against the Company in the courts of any appropriate jurisdiction
or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. 
 (d) THE
PARTIES HERETO HEREBY WAIVE TRIAL BY JURY IN ANY ACTION BROUGHT ON
OR WITH RESPECT TO THIS AGREEMENT, THE NOTES OR ANY OTHER DOCUMENT
EXECUTED IN CONNECTION HEREWITH OR THEREWITH.

 GUARANTY 
 THIS
GUARANTY (as the same may be amended, restated, supplemented or otherwise modified from time to time, this “Guaranty”) is made as of July 10, 2015, by Stepan Specialty Products, LLC, a Delaware limited liability company (together
with any Subsidiaries which become parties to this Guaranty by executing a Supplement hereto in the form attached hereto as Annex I, the “Guarantors”), for the benefit of the holders from time to time of the Notes (as defined
below) (the “Holders”). 
 WITNESSETH: 

WHEREAS, Stepan Company, a Delaware corporation (the “Borrower”), has entered into that certain Note Purchase Agreement,
dated as of July 10, 2015 (the “Note Purchase Agreement”), by and among the Borrower and the purchasers named therein. 

WHEREAS, the Borrower has authorized the issuance of and, pursuant to the Note Purchase Agreement, proposes to issue and sell on the date
hereof its 3.95% Senior Notes, due July 10, 2027 (the “Notes”) pursuant to the Note Purchase Agreement. 
 WHEREAS,
pursuant to Section 9.8 of the Note Purchase Agreement, the Borrower has agreed that certain of its Subsidiaries (each a “Guarantor” and, collectively, the “Guarantors”) will guarantee the Borrower’s
obligations under the Notes and the Note Purchase Agreement; 
 WHEREAS, the Guarantors hereby execute and deliver this Guaranty, whereby
each of the Guarantors, without limitation and with full recourse, shall guarantee the payment when due of all of the “Guaranteed Obligations” (as defined below); and 

WHEREAS, the Guarantors each acknowledge that they have and will continue to derive substantial benefits from the issuance of the Notes, and
each of the Guarantors is willing to guarantee the Guaranteed Obligations; 
 NOW, THEREFORE, in consideration of the foregoing premises and
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 

SECTION 1. Definitions. Terms defined in the Note Purchase Agreement and not otherwise defined herein have, as used herein, the
respective meanings provided for therein. 
 SECTION 2. Representations, Warranties and Covenants. Each of the Guarantors represents
and warrants to each Holder as of the date of this Agreement that: 
 (A) It (i) is a corporation, partnership or limited liability
company, duly incorporated or organized, as the case may be, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization, (ii) is duly qualified to do business as a foreign entity and is in good
standing under the laws of each jurisdiction where the business by it makes such qualification necessary, and (iii) has all 

  
 EXHIBIT
2.2 
 (to Note Purchase Agreement) 

 requisite corporate, partnership or limited liability power and authority, as the case may be, to own, operate
and encumber its property and to conduct its business in each jurisdiction in which its business is conducted except to the extent that the failure to have such authority could not reasonably be expected to have a material adverse effect (a) on
the business, financial condition, operations or properties of a Guarantor taken as a whole or (b) on its ability to perform its obligations hereunder. 

(B) It has the requisite corporate, limited liability company or partnership, as applicable, power and authority and legal right to execute and
deliver this Guaranty and to perform its obligations hereunder. The execution and delivery by it of this Guaranty and the performance of each of its obligations hereunder have been duly authorized by proper proceedings, and this Guaranty constitutes
a legal, valid and binding obligation of each Guarantor, enforceable against such Guarantor, in accordance with its terms, except as enforceability may be limited by (i) bankruptcy, insolvency, fraudulent conveyances or transfers,
reorganization or similar laws relating to or affecting the enforcement of creditors’ rights generally, (ii) general equitable principles (whether considered in a proceeding in equity or at law), and (iii) requirements of
reasonableness, good faith and fair dealing. 
 (C) Neither the execution and delivery by it of this Guaranty, nor the consummation by it of
the transactions herein contemplated, nor compliance by it with the terms and provisions hereof, will (i) conflict with the charter or other organizational documents of such Guarantor, (ii) conflict with, result in a breach of or
constitute (with or without notice or lapse of time or both) a default under any law, rule, regulation, order, writ, judgment, injunction, decree or award (including, without limitation, any environmental property transfer laws or regulations)
applicable to such Guarantor or any provisions of any indenture, instrument or agreement to which such Guarantor is party or is subject or which it or its property is bound or affected, or require termination of any such indenture, instrument or
agreement, (iii) result in or require the creation or imposition of any Lien whatsoever upon any of the property or assets of such Guarantor, other than Liens permitted or created by the Note Purchase Agreement, or (iv) require any
approval of such Guarantor’s board of directors or shareholders or unitholders except such as have been obtained. The execution, delivery and performance by the Guarantors of this Guaranty do not and will not require any registration with,
consent or approval of, or notice to, or other action to, with or by any governmental authority, including under any environmental property transfer laws or regulations, except filings, consents or notices which have been made. 

In addition to the foregoing, each of the Guarantors covenants that, so long as any amount is payable under the Note Purchase Agreement or the
Notes or any other Guaranteed Obligations shall remain unpaid, it will, and, if necessary, will enable the Borrower to, fully comply with those covenants and agreements of the Borrower applicable to such Guarantor set forth in the Note Purchase
Agreement. 
 SECTION 3. The Guaranty. Each of the Guarantors hereby unconditionally guarantees, jointly with the other Guarantors
and severally, as a primary obligor and not merely as a surety, to each Holder and its successors, transfers and assigns, the full and punctual payment and performance when due, whether at stated maturity, upon acceleration or otherwise, of the
principal of and Make-Whole Amount and interest on (including, without limitation, interest whether or not an allowable claim, accruing after the date of filing of any petition in bankruptcy, or the commencement of any bankruptcy, insolvency or
similar proceeding relating to the Borrower) the Notes issued from time to time, including Additional Notes issued after the date hereof, and all other amounts under the Note Purchase Agreement and all other obligations, agreements and covenants of
the Borrower now or hereafter existing under the Note Purchase Agreement whether for 

  
 S-2.2-2 

 
principal, Make-Whole Amount, interest (including interest accruing both prior to and subsequent to the commencement of any proceeding against or with respect to the Borrower under any chapter of
the Bankruptcy Code), indemnification payments, expenses (including attorneys’ fee and expenses) or otherwise, and all costs and expenses, if any, incurred by any Holder in connection with enforcing any rights under this Guaranty (all of the
foregoing being referred to collectively as the “Guaranteed Obligations” and the holders from time to time of the Guaranteed Obligations being referred to collectively as the “Holders of Guaranteed Obligations”).
Upon (x) the failure by the Borrower to pay punctually any such amount or perform such obligation, and (y) such failure continuing beyond any applicable grace or notice and cure period, each of the Guarantors agrees that it shall forthwith
on demand pay such amount or perform such obligation at the place and in the manner specified in the Note Purchase Agreement. Each of the Guarantors hereby agrees that this Guaranty is an absolute, irrevocable, unconditional, present and continuing
guaranty of payment and is not a guaranty of collection, and is no way conditioned upon any attempt to collect from the Borrower or any other action, occurrence or circumstance whatsoever. 

Notwithstanding any stay, injunction or other prohibition preventing such action against the Borrower, if for any reason whatsoever the
Borrower shall fail or be unable duly, punctually and fully to perform and (in the case of the payment of the Guaranteed Obligations) pay such amounts as and when the same shall become due and (in the case of the payment of the Guaranteed
Obligations) payable or to perform or comply with any other Guaranteed Obligation, whether or not such failure or inability shall constitute an “Event of Default” under the Note Purchase Agreement or the Notes, each Guarantor will
forthwith (in the case of the payment of Guaranteed Obligations) pay or cause to be paid such amounts to the Holders, in lawful money of the United States of America, at the place specified in the Note Purchase Agreement, or perform or comply with
such Guaranteed Obligations or cause such Guaranteed Obligations to be performed or complied with, (in the case of the payment of Guaranteed Obligations) together with interest (in the amounts and to the extent required under such Notes) on any
amount due and owing. 
 SECTION 4. Guaranty Unconditional. The obligations of each of the Guarantors hereunder shall be
unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by: 

(A) any extension, renewal, settlement, indulgence, compromise, waiver or release of or with respect to the Guaranteed
Obligations or any part thereof or any agreement relating thereto, or with respect to any obligation of any other guarantor of any of the Guaranteed Obligations, whether (in any such case) by operation of law or otherwise, or any failure or omission
to enforce any right, power or remedy with respect to the Guaranteed Obligations or any part thereof or any agreement relating thereto, or with respect to any obligation of any other guarantor of any of the Guaranteed Obligations; 

(B) any modification or amendment of or supplement to the Note Purchase Agreement, including, without limitation, any such
amendment which may increase the amount of, or the interest rates applicable to, any of the Guaranteed Obligations guaranteed hereby; 

(C) any release, surrender, compromise, settlement, waiver, subordination or modification, with or without consideration, of
any collateral securing the Guaranteed Obligations or any part thereof, any other guaranties with respect to the Guaranteed Obligations or any part thereof, or any other obligation of any person or entity with respect to the Guaranteed Obligations
or any part thereof, or any nonperfection or invalidity of any direct or indirect security for the Guaranteed Obligations; 

  
 S-2.2-3 

 (D) any change in the corporate, partnership or other existence, structure or
ownership of the Borrower or any other guarantor of any of the Guaranteed Obligations, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Borrower or any other guarantor of the Guaranteed Obligations, or any of
their respective assets or any resulting release or discharge of any obligation of the Borrower or any other guarantor of any of the Guaranteed Obligations; 

(E) the existence of any claim, setoff or other rights which the Guarantors may have at any time against the Borrower, any
other guarantor of any of the Guaranteed Obligations, any Holder of Guaranteed Obligations or any other Person, whether in connection herewith or in connection with any unrelated transactions; provided that nothing herein shall prevent the
assertion of any such claim by separate suit or compulsory counterclaim; 
 (F) the enforceability or validity of the
Guaranteed Obligations or any part thereof or the genuineness, enforceability or validity of any agreement relating thereto or with respect to any collateral securing the Guaranteed Obligations or any part thereof, or any other invalidity or
unenforceability relating to or against the Borrower or any other guarantor of any of the Guaranteed Obligations, for any reason related to the Note Purchase Agreement, the Notes or any provision of applicable law, decree, order or regulation of any
jurisdiction purporting to prohibit the payment by the Borrower or any other guarantor of the Guaranteed Obligations, of any of the Guaranteed Obligations or otherwise affecting any term of any of the Guaranteed Obligations; 

(G) the failure of the Holders to take any steps to perfect and maintain any security interest in, or to preserve any rights
to, any security or collateral for the Guaranteed Obligations, if any; 
 (H) the election by, or on behalf of, any one or
more of the Holders of Guaranteed Obligations, in any proceeding instituted under Chapter 11 of Title 11 of the United States Code (11 U.S.C. 101 et seq.) (the “Bankruptcy Code”), of the application of Section 1111(b)(2) of the
Bankruptcy Code; 
 (I) any borrowing or grant of a security interest by the Borrower, as debtor-in-possession, under
Section 364 of the Bankruptcy Code; 
 (J) the disallowance, under Section 502 of the Bankruptcy Code, of all or
any portion of the claims of the Holders of Guaranteed Obligations for repayment of all or any part of the Guaranteed Obligations; 

(K) the failure of any other guarantor to sign or become party to this Guaranty or any amendment, change, or reaffirmation
hereof; or 
 (L) any other act or omission to act or delay of any kind by the Borrower, any other guarantor of the

obligations hereunder except as provided in Section 5. 

  
 S-2.2-4 

 SECTION 5. Discharge Only Upon Payment In Full: Reinstatement In Certain Circumstances.

 (A) Each of the Guarantors’ obligations hereunder shall remain in full force and effect and shall not be discharged
until such time as all of the principal of, Make-Whole Amount and interest on the Notes, the other Guaranteed Obligations and all other independent payment obligations of such Guarantor under the Guaranty shall have been paid in full in cash and
performed in full, and all of the agreements of each of the other Guarantors hereunder shall be duly paid in cash and performed in full. If at any time any payment of the principal of, Make-Whole Amount, or interest on any Note or any other amount
payable by the Borrower or any other party under the Note Purchase Agreement or any Note is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise, each of the
Guarantors’ obligations hereunder with respect to such payment shall be reinstated as though such payment had been due but not made at such time. 

(B) A Guarantor shall automatically be released from its obligations hereunder in the event that all of the capital stock of
such Guarantor shall be sold, transferred or otherwise disposed of, or the assets of such Guarantor shall be sold, transferred or otherwise disposed of substantially in their entirety, in each case to a Person that is not the Borrower in accordance
with the terms of the Note Purchase Agreement. 
 (C) In connection with any termination or release pursuant to paragraph
(A) or (B) of this Section 5 the Holders shall execute and deliver to any Guarantor, as the case may be, at such Guarantor’s expense, all documents that such Guarantor shall reasonably request to evidence such termination or
release. Any execution and delivery of documents pursuant to this Section 5 shall be without recourse to or warranty by the Holders. 

SECTION 6. General Waivers; Additional Waivers. 

(A) General Waivers. Each of the Guarantors irrevocably waives acceptance hereof, presentment, demand or action on
delinquency, protest, the benefit of any statutes of limitations and, to the fullest extent permitted by law, any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Borrower, any
other guarantor of the Guaranteed Obligations, or any other Person. 
 (B) Additional Waivers. Notwithstanding
anything herein to the contrary, each of the Guarantors hereby absolutely, unconditionally, knowingly, and expressly waives: 

(i) any right it may have to revoke this Guaranty as to future indebtedness or notice of acceptance hereof; 

(ii) (a) notice of acceptance hereof; (b) notice of any financial accommodations made or extended under the Note
Purchase Agreement or the creation or existence of any Guaranteed Obligations; (c) notice of the amount of the Guaranteed Obligations, subject, however, to each 

  
 S-2.2-5 

 
Guarantor’s right to make inquiry of the Holders of Guaranteed Obligations to ascertain the amount of the Guaranteed Obligations at any reasonable time; (d) notice of any adverse change
in the financial condition of the Borrower or of any other fact that might increase such Guarantor’s risk hereunder; (e) notice of presentment for payment, demand, protest, and notice thereof as to any instruments under the Note Purchase
Agreement or the Notes; (f) notice of any Default or Event of Default; and (g) all other notices (except if such notice is specifically required to be given to such Guarantor hereunder or under the Note Purchase Agreement) and demands to
which each Guarantor might otherwise be entitled; 
 (iii) its right, if any, to require the Holders of Guaranteed
Obligations to institute suit against, or to exhaust any rights and remedies which the Holders of Guaranteed Obligations have or may have against, the other Guarantors or any third party, or against any collateral provided by the other Guarantors,
or any third party; and each Guarantor further waives any defense arising by reason of any disability or other defense (other than the defense that the Guaranteed Obligations shall have been fully and finally performed and indefeasibly paid) of the
other Guarantors or by reason of the cessation from any cause whatsoever of the liability of the other Guarantors in respect thereof; 

(iv) (a) any rights to assert against the Holders of Guaranteed Obligations any defense (legal or equitable), set-off,
counterclaim, or claim which such Guarantor may now or at any time hereafter have against the other Guarantors or any other party liable to the Holders of Guaranteed Obligations; (b) any defense, set-off, counterclaim, or claim, of any kind or
nature, arising directly or indirectly from the present or future lack of perfection, sufficiency, validity, or enforceability of the Guaranteed Obligations or any security therefor; (c) any defense such Guarantor has to performance hereunder,
and any right such Guarantor has to be exonerated, arising by reason of: the impairment or suspension of the Holders of Guaranteed Obligations’ rights or remedies against the other Guarantors; the alteration by the Holders of Guaranteed
Obligations of the Guaranteed Obligations; any discharge of the other Guarantors’ obligations to the Holders of Guaranteed Obligations by operation of law as a result of the Holders of Guaranteed Obligations’ intervention or omission; or
the acceptance by the Holders of Guaranteed Obligations of anything in partial satisfaction of the Guaranteed Obligations; and (d) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement
thereof, and any act which shall defer or delay the operation of any statute of limitations applicable to the Guaranteed Obligations shall similarly operate to defer or delay the operation of such statute of limitations applicable to such
Guarantor’s liability hereunder; and 
 (v) any defense arising by reason of or deriving from (a) any claim or
defense based upon an election of remedies by the Holders of Guaranteed Obligations; or (b) any election by the Holders of Guaranteed Obligations under Section 1111(b) of Title 11 of the United States Code entitled “Bankruptcy”,
as now and hereafter in effect (or any successor statute), to limit the amount of, or any collateral securing, its claim against the Guarantors. 

  
 S-2.2-6 

 SECTION 7. Subordination of Subrogation; Subordination of Intercompany Indebtedness. 

(A) Subordination of Subrogation. Until the Guaranteed Obligations have been fully and finally performed and
indefeasibly paid in full in cash (other than contingent indemnity obligations), the Guarantors (i) shall have no right of subrogation with respect to such Guaranteed Obligations and (ii) waive any right to enforce any remedy which the
Holders of Guaranteed Obligations now have or may hereafter have against the Borrower, any endorser or any guarantor of all or any part of the Guaranteed Obligations or any other Person, and the Guarantors waive any benefit of, and any right to
participate in, any security or collateral given to the Holders of Guaranteed Obligations to secure the payment or performance of all or any part of the Guaranteed Obligations or any other liability of the Borrower to the Holders of Guaranteed
Obligations. Should any Guarantor have the right, notwithstanding the foregoing, to exercise its subrogation rights, each Guarantor hereby expressly and irrevocably (a) subordinates any and all rights at law or in equity to subrogation,
reimbursement, exoneration, contribution, indemnification or set off that such Guarantor may have to the indefeasible payment in full in cash of the Guaranteed Obligations (other than contingent indemnity obligations) and (b) waives any and all
defenses available to a surety, guarantor or accommodation co-obligor until the Guaranteed Obligations are indefeasibly paid in full in cash and performed in full. Each Guarantor acknowledges and agrees that this subordination is intended to benefit
the Holders of Guaranteed Obligations and shall not limit or otherwise affect such Guarantor’s liability hereunder or the enforceability of this Guaranty, and that the Holders of Guaranteed Obligations and their successors and assigns are
intended third party beneficiaries of the waivers and agreements set forth in this Section 7(A). 
 (B) Subordination
of Intercompany Indebtedness. Each Guarantor agrees that any and all claims of such Guarantor against the Borrower or any other Guarantor hereunder (each an “Obligor”) with respect to any “Intercompany Indebtedness”
(as hereinafter defined), any endorser, obligor or any other guarantor of all or any part of the Guaranteed Obligations, or against any of its properties shall be subordinate and subject in right of payment to the prior payment, in full and in cash,
of all Guaranteed Obligations; provided that, as long as no Event of Default has occurred and is continuing, such Guarantor may receive payments of principal and interest from any Obligor with respect to Intercompany Indebtedness.
Notwithstanding any right of any Guarantor to ask, demand, sue for, take or receive any payment from any Obligor, all rights, liens and security interests of such Guarantor, whether now or hereafter arising and howsoever existing, in any assets of
any other Obligor shall be and are subordinated to the rights of the Holders of Guaranteed Obligations in those assets. No Guarantor shall have any right to possession of any such asset or to foreclose upon any such asset, whether by judicial action
or otherwise, unless and until all of the Guaranteed Obligations shall have been fully paid and satisfied (in cash) and fully performed. If all or any part of the assets of any Obligor, or the proceeds thereof, are subject to any distribution,
division or application to the creditors of such Obligor, whether partial or complete, voluntary or involuntary, and whether by reason of liquidation, bankruptcy, arrangement, receivership, assignment for the benefit of creditors or any other action
or proceeding, or if the business of any such Obligor is dissolved or if substantially all of the assets of any such Obligor are sold, then, and in any such event (such events being herein referred to as an “Insolvency Event”), any
payment or distribution of any kind or character, either in cash, securities or other property, which shall be payable or deliverable upon or with respect to any indebtedness of any Obligor to any Guarantor (“Intercompany
Indebtedness”) shall be paid or delivered directly to the Holders for application on any of the Guaranteed Obligations, due or to become due, until such Guaranteed Obligations shall have first been fully paid and satisfied (in cash).
Should any payment, distribution, security or instrument or proceeds thereof be received by the applicable Guarantor upon or with respect to the Intercompany Indebtedness after any Insolvency Event and prior to the satisfaction of all of the 

  
 S-2.2-7 

 
Guaranteed Obligations, such Guarantor shall receive and hold the same in trust, as trustee, for the benefit of the Holders of Guaranteed Obligations and shall forthwith deliver the same to the
Holders of Guaranteed Obligations, in precisely the form received (except for the endorsement or assignment of the Guarantor where necessary), for application to any of the Guaranteed Obligations, due or not due, and, until so delivered, the same
shall be held in trust by the Guarantor as the property of the Holders of Guaranteed Obligations. If any such Guarantor fails to make any such endorsement or assignment to the Holders of Guaranteed Obligations, the Holders of Guaranteed Obligations
or any of their officers or employees are irrevocably authorized to make the same. Each Guarantor agrees that until the Guaranteed Obligations (other than the contingent indemnity obligations) have been paid in full (in cash) and satisfied and fully
performed, no Guarantor will assign or transfer to any Person any claim any such Guarantor has or may have against any Obligor. 
 SECTION
8. Contribution with Respect to Guaranteed Obligations. 
 (A) To the extent that any Guarantor shall make a payment
under this Guaranty (a “Guarantor Payment”) which, taking into account all other Guarantor Payments then previously or concurrently made by any other Guarantor, exceeds the amount which otherwise would have been paid by or
attributable to such Guarantor if each Guarantor had paid the aggregate Guaranteed Obligations satisfied by such Guarantor Payment in the same proportion as such Guarantor’s “Allocable Amount” (as defined below) (as determined
immediately prior to such Guarantor Payment) bore to the aggregate Allocable Amounts of each of the Guarantors as determined immediately prior to the making of such Guarantor Payment, then, following indefeasible payment in full in cash of the
Guaranteed Obligations and termination of the Note Purchase Agreement, such Guarantor shall be entitled to receive contribution and indemnification payments from, and be reimbursed by, each other Guarantor for the amount of such excess, pro rata
based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment. 
 (B) As of any date of
determination, the “Allocable Amount” of any Guarantor shall be equal to the excess of the fair value of the property of such Guarantor over the total liabilities of such Guarantor (including the maximum amount reasonably expected to
become due in respect of contingent liabilities, calculated, without duplication, assuming each other Guarantor that is also liable for such contingent liability pays its ratable share thereof), giving effect to all payments made by other Guarantors
as of such date in a manner to maximize the amount of such contributions. 
 (C) This Section 8 is intended only to
define the relative rights of the Guarantors, and nothing set forth in this Section 8 is intended to or shall impair the obligations of the Guarantors, jointly and severally, to pay any amounts as and when the same shall become due and payable
in accordance with the terms of this Guaranty. 
 (D) The parties hereto acknowledge that the rights of contribution and
indemnification hereunder shall constitute assets of the Guarantor or Guarantors to which such contribution and indemnification is owing. 

(E) The rights of the indemnifying Guarantors against other Guarantors under this Section 8 shall be exercisable upon the
full and indefeasible payment of the Guaranteed Obligations in cash, the performance in full of the Guaranteed Obligations and the termination of the Note Purchase Agreement. 

  
 S-2.2-8 

 (F) In determining the solvency of any Guarantor, it is the intention of the
parties hereto that any rights of subrogation or contribution which such Guarantor may have under this Guaranty, any other agreement or applicable law shall be taken into account. 

SECTION 9. Limitation of Obligations. Notwithstanding any other provision of this Guaranty, each Guarantor’s obligation to pay the
amount guaranteed by each Guarantor hereunder shall be limited to the extent, if any, required so that its obligations hereunder shall not be subject to avoidance under Section 548 of the Bankruptcy Code or under any applicable state Uniform
Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law. 
 SECTION 10. Stay of Acceleration. If
acceleration of the time for payment of any amount payable by the Borrower under the Note Purchase Agreement or any Note is stayed upon the insolvency, bankruptcy or reorganization of the Borrower, all such amounts otherwise subject to acceleration
under the terms of the Note Purchase Agreement or any Note shall nonetheless be payable by each of the Guarantors hereunder forthwith on demand by the Holders. 

SECTION 11. Notices. All notices, requests and other communications to any party hereunder shall be given in the manner prescribed in
the Note Purchase Agreement with respect to the Holders at their notice address therein and with respect to any Guarantor, in care of the Borrower at the address of the Borrower set forth in the Note Purchase Agreement or such other address or
telecopy number as such party may hereafter specify for such purpose by notice in accordance with the provisions of the Note Purchase Agreement. 

SECTION 12. No Waivers. No failure or delay by the Holder of Guaranteed Obligations in exercising any right, power or privilege
hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies provided in this Guaranty,
the Note Purchase Agreement, and the Notes shall be cumulative and not exclusive of any rights or remedies provided by law. 
 SECTION
13. Successors and Assigns. This Guaranty is for the benefit of the Holders and the Holders of Guaranteed Obligations and their respective successors, transfers and permitted assigns; provided, that no Guarantor shall have any right to
assign its rights or obligations hereunder without the consent of all of the Holders, and any such assignment in violation of this Section 13 shall be null and void; and in the event of an assignment of any amounts payable under the Note
Purchase Agreement or the Notes in accordance with the respective terms thereof, the rights hereunder, to the extent applicable to the indebtedness so assigned, may be transferred with such indebtedness. This Guaranty shall be binding upon each of
the Guarantors and their respective successors and assigns. 
 SECTION 14. Changes in Writing. Other than in connection with the
addition of additional Subsidiaries, which become parties hereto by executing a supplement hereto in the form attached as Annex I, neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated orally, but only in
writing signed by each of the Guarantors and the Holders.

GOVERNED BY THE LAW OF THE STATE OF NEW YORK. 
 SECTION 16. CONSENT TO JURISDICTION; SERVICE OF PROCESS; JURY TRIAL. 

(A) CONSENT TO JURISDICTION. EACH GUARANTOR HEREBY IRREVOCABLY SUBMITS TO THE
NON-EXCLUSIVE JURISDICTION OF ANY NEW YORK STATE OR FEDERAL COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, IN ANY ACTION OR PROCEEDING ARISING OUT OF
OR RELATING TO THE NOTE PURCHASE AGREEMENT OR ANY NOTE AND EACH GUARANTOR HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW
OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF ANY HOLDER OF GUARANTEED OBLIGATIONS TO BRING PROCEEDINGS AGAINST
ANY GUARANTOR IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY ANY GUARANTOR AGAINST ANY HOLDER OF GUARANTEED OBLIGATIONS INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS
GUARANTY OR ANY OTHER RELATED DOCUMENT SHALL BE BROUGHT ONLY IN A COURT SITTING IN THE BOROUGH OF MANHATTAN, THE CITY OF NEW YORK. 

(B) WAIVER OF JURY TRIAL. EACH GUARANTOR HEREBY WAIVES TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS GUARANTY, THE NOTE PURCHASE AGREEMENT OR ANY NOTE OR THE RELATIONSHIP ESTABLISHED THEREUNDER. 

SECTION 17. No Strict Construction. The parties hereto have participated jointly in the negotiation and drafting of this Guaranty. In
the event an ambiguity or question of intent or interpretation arises, this Guaranty shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Guaranty. 
 SECTION 18. Taxes, Expenses of Enforcement, etc. 

(A) Taxes. 

(i) All payments by any Guarantor to or for the account of any Holder of Guaranteed Obligations hereunder or under any
promissory note shall be made free and clear of and without deduction for any and all taxes. If any Guarantor shall be required by law to deduct any taxes from or in respect of any sum payable hereunder to any Holder of Guaranteed Obligations,
(a) the sum payable shall be increased as necessary so that after making all required deductions (including 

  
 S-2.2-10 

 
deductions applicable to additional sums payable under this Section 18(A)) such Holder or Holder of Guaranteed Obligations (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (b) such Guarantor shall make such deductions, (c) such Guarantor shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) such Guarantor shall furnish to the
Holders the original copy of a receipt evidencing payment thereof within ten (10) days after such payment is made. 
 (ii) In
addition, the Guarantors hereby agree to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any promissory note or from the
execution or delivery of, or otherwise with respect to, this Guaranty or any promissory note (“Other Taxes”). 

(iii) The Guarantors hereby agree to indemnify the Holder of Guaranteed Obligations for the full amount of taxes or Other Taxes
(including, without limitation, any taxes or Other Taxes imposed on amounts payable under this Section 18(A)) paid by any Holder or Holder of Guaranteed Obligations and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto. Payments due under this indemnification shall be made within thirty (30) days of the date the Holder of Guaranteed Obligations makes demand therefor. 

(B) Expenses of Enforcement, Etc. Subject to the terms of the Note Purchase Agreement, after the occurrence of a Default
under the Note Purchase Agreement, the Holders shall have the right at any time to commence enforcement proceedings with respect to the Guaranteed Obligations. The Guarantors agree to reimburse the Holders and Holders of Guaranteed Obligations for
any costs and out-of-pocket expenses (including reasonable attorneys’ fees and time charges of attorneys for the Holders), paid or incurred by any Holder or Holder of Guaranteed Obligations in connection with the collection and enforcement of
amounts due under the Note Purchase Agreement, the Notes and this Guaranty. 
 SECTION 19. Setoff. At any time after all or any part
of the Guaranteed Obligations have become due and payable (by acceleration or otherwise), each Holder of Guaranteed Obligations may, without notice to any Guarantor and regardless of the acceptance of any security or collateral for the payment
hereof, appropriate and apply in accordance with the terms of the Note Purchase Agreement and the Notes toward the payment of all or any part of the Guaranteed Obligations (i) any indebtedness due or to become due from such Holder of Guaranteed
Obligations to any Guarantor, and (ii) any moneys, credits or other property belonging to any Guarantor, at any time held by or coming into the possession of such Holder of Guaranteed Obligations or any of their respective affiliates.

of the Borrower and any and all endorsers and/or other Guarantors of all or any part of the Guaranteed Obligations, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations, or any part thereof, that diligent
inquiry would reveal, and each Guarantor hereby agrees that none of the Holders of Guaranteed Obligations shall have any duty to advise such Guarantor of information known to any of them regarding such condition or any such circumstances. In the
event any Holder of Guaranteed Obligations in its sole discretion, undertakes at any time or from time to time to provide any such information to a Guarantor, such Holder of Guaranteed Obligations shall be under no obligation (i) to undertake
any investigation not a part of its regular business routine, (ii) to disclose any information which such Holder of Guaranteed Obligations, pursuant to accepted or reasonable commercial finance practices, wishes to maintain confidential or
(iii) to make any other or future disclosures of such information or any other information to such Guarantor. 

  
 S-2.2-11 

 SECTION 21. Severability. Wherever possible, each provision of this Guaranty shall be
interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Guaranty shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity
without invalidating the remainder of such provision or the remaining provisions of this Guaranty.

Subsidiary Guaranty (the “Transaction Documents”) to which it is a party and to perform its obligations thereunder. 
 2.
Assuming the proceeds of the Notes are used solely for the purposes set forth in the Note Purchase Agreement, neither the execution and delivery by the Company or the Guarantor of the Transaction Documents to which it is a party, nor the performance
by the Company or the Guarantor of its obligations thereunder (including the issuance and sale of the Notes): (i) results in the breach of, or constitutes a default under, any material indenture, mortgage, deed of trust, lease or sublease
agreement to which the Company or the Guarantor is a party or by which it or any of its properties is bound; (ii) results in the creation or imposition of any lien upon any of the property of the Company or the Guarantor under any indenture,
mortgage or other agreement described in clause (i) above; or (iii) requires the consent or approval of, or withholding of objection, or any filing of qualification or registration with, any governmental body, agency or authority other
than those which have been obtained. 
 3. Except as disclosed in the Note Purchase Agreement or the Subsidiary Guaranty, there are no
actions, suits, or proceedings pending or overtly threatened against the Company or the Guarantor or any of their assets and properties that questions or may affect the validity of any action to be taken by the Company or the Guarantor pursuant to
the Transaction Documents, or that seeks to restrain the Company or the Guarantor from carrying out the transactions contemplated therein or the Company’s or the Guarantor’s obligations thereunder.

company action of the Guarantor. 
 (3) Each Company Document has been duly executed and delivered on behalf of the Company and, when the
Notes are delivered against payment therefor in accordance with the terms of the Note Purchase Agreement, constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. The Guaranty has been
duly executed and delivered on behalf of the Guarantor and, when the Notes are delivered against payment therefor in accordance with the terms of the Note Purchase Agreement, constitutes a valid and binding obligation of the Guarantor, enforceable

the Note Purchase Agreement, the execution and delivery to the Purchasers by the Company of the Note Purchase Agreement and the performance by the Company of its obligations thereunder, and the issuance and sale of the Notes: (i) do not
contravene any provision of the Company Certificate of Incorporation or the Company By-Laws; and (ii) do not violate (A) any present law, or present regulation of any governmental agency or authority, of the State of New York or the United
States of America applicable to the Company or its property or (B) any court decree or order binding upon the Company or its property that is listed on Annex I to the Company Officer’s Certificate (this opinion being limited in that we
express no opinion (1) with respect to any violation not readily ascertainable from the face of any such decree or order, or arising under or based upon any cross default provision insofar as it relates to a default under an agreement not so
identified to us, or arising under or based upon any covenant of a financial or numerical nature or requiring computation or (2) as to any law which might be violated by any misrepresentation or omission or a fraudulent act).

 (6) Neither the Company nor the Guarantor is required to
register as an “investment company” (under, and as defined in, the Investment Company Act of 1940, as amended (the “1940 Act”)) or, to our knowledge, is a company controlled by a company required to register as such under the

contemplated by the Note Purchase Agreement, it is not necessary in connection with the offer and sale of the Notes to the Purchasers under the Note Purchase Agreement to register the Notes under the Securities Act of 1933, as amended. 

(8) The issuance by the Company of the Notes and the application of the proceeds thereof as provided in the Note Purchase Agreement will not
