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

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, 2002.

(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.

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

(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. 
 (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

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

 (b) Except as disclosed in Schedule 5.15, neither the Company nor any Restricted Subsidiary has agreed or consented to
cause or permit any of its property, whether now owned or hereafter acquired, to be subject to a Lien that secures Debt or to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or

 (c) Neither the Company nor any Subsidiary is a party to, or
otherwise subject to any provision contained in, any instrument evidencing Debt of the Company or such Subsidiary, any agreement relating thereto or any other agreement (including, but not limited to, its charter or other organizational document)
which limits the amount of, or otherwise imposes restrictions on the incurring of, Debt of the Company, except the agreements specifically identified in Schedule 5.15.

connection with such Purchaser’s fixed contractual obligations under which the amounts payable, or credited, to any employee benefit plan (or its related trust) that has any interest in such separate account (or to any participant or
beneficiary of such plan (including any annuitant)) are not affected in any manner by the investment performance of the separate account; or

 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

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

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,

 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

  
 -21-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
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. 
 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 (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 as provided in subparagraph (f) of this Section 8.7. 
 (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.

 (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

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 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 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 

  
 -37-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
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 other Person 

  
 -38-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
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 notice to each holder of a Note, change the place of payment of the Notes so long as such place of payment shall be either the
principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such 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.	EXPENSES, ETC. 

 Section 15.1. Transaction Expenses. Whether or not the transactions contemplated hereby are consummated, the Company will pay all costs and expenses (including reasonable attorneys’ fees
of a special counsel and, if reasonably required by the Required Holders, local or other counsel) incurred by the Purchasers 

  
 -39-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
and each other holder of a Note in connection with such transactions and in connection with any amendments, waivers or consents under or in respect of this Agreement, any Subsidiary Guaranty or
the Notes (whether or not such amendment, waiver or consent becomes effective) within 15 Business Days after the Company’s receipt of any invoice therefor, including, without limitation: (a) the costs and expenses incurred in enforcing or
defending (or determining whether or how to enforce or defend) any rights under this Agreement, any Subsidiary Guaranty or the Notes or in responding to any subpoena or other legal process or informal investigative demand issued in connection with
this Agreement, any Subsidiary Guaranty or the Notes, or by reason of being a holder of any Note, (b) the costs and expenses, including financial advisors’ fees, incurred in connection with the insolvency or bankruptcy of the Company or
any Subsidiary or in connection with any work-out or restructuring of the transactions contemplated hereby and by the Notes and any Subsidiary Guaranty and (c) the costs and expenses incurred in connection with the initial filing of this
Agreement and all related documents and financial information with the SVO provided, that such costs and expenses under this clause (c) shall not exceed $3,500. The Company will pay, and will save each Purchaser and each other holder of
a Note harmless from, all claims in respect of any fees, costs or expenses, if any, of brokers and finders (other than those, if any, retained by a Purchaser or other holder in connection with its purchase of the Notes). 

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. 
  

	SECTION 16.	SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE 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 AND WAIVER. 

 Section 17.1. Requirements. This Agreement and the Notes may be amended, and the 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, 

  
 -40-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
2, 3, 4, 5, 6 or 21 hereof, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by such Purchaser in writing; and (b) no amendment or
waiver may, without the written consent of each Purchaser and the holder of each Note at the time outstanding, (i) subject to Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or payment of
principal of, or reduce the rate or change the time of payment or method of computation of (x) interest on the Notes or (y) the Make-Whole Amount, (ii) change the percentage of the principal amount of the Notes the holders of which
are required to consent to any amendment or waiver, or (iii) amend any of Sections 8 (except as set forth in the second sentence of Section 8.2, 11(a), 11(b), 12, 17 or 20. 

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. 
 (c) Consent in
Contemplation of Transfer. Any consent given pursuant to this Section 17 or any Subsidiary Guaranty by a holder of a Note that has transferred or has agreed to transfer its Note to the Company, any Subsidiary or any Affiliate of the Company
in connection with such consent shall be void and of no force or effect except solely as to such holder, and any amendments 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 

  
 -41-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
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 18.	NOTICES. 

 Except

recognized overnight delivery service (charges prepaid), or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by an internationally recognized overnight delivery service (with charges prepaid). Any

 (ii) if to any other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing, or 

(iii) if to the Company, to the Company at its address set forth at the beginning hereof to the attention of Chief
Financial Officer, with a copy to the General Counsel, or at such other address as the Company shall have specified to the holder of each Note in writing. 
 Notices under this Section 18 will be deemed given only when actually received.

 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

  
 -42-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
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 

  
 -43-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
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 8.4 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

  
 -44-

			
	STEPAN COMPANY	  	NOTE PURCHASE AGREEMENT

 

 
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
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.

 This Note is one of a series of Senior Notes (herein called the

representation set forth in Section 6.2 of the Note Purchase Agreement. Unless otherwise indicated, capitalized terms used in this Note shall have the respective meanings ascribed to such terms in the Note Purchase Agreement. 

This Note is a registered Note and, as provided in the Note Purchase Agreement, upon surrender of this Note for registration of transfer,
duly endorsed, or accompanied by a written instrument of transfer duly executed, by the registered holder hereof or such holder’s attorney duly authorized in writing, a new Note for a like principal amount will be issued to, and registered in

 FORM OF SUBSIDIARY GUARANTY

  

EXHIBIT 2.2 
 (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. 

  

EXHIBIT 4.4(a) 
 (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 

  

EXHIBIT 4.4(b) 
 (to Note Purchase Agreement) 

 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.
