Credit Suisse Securities (USA) LLC (“Credit Suisse”), Nomura Securities International, Inc. (“Nomura”) and Deutsche Bank Securities Inc. (“Deutsche Bank”) have agreed to act as the representatives of the Initial Purchasers (the “Representatives”) in connection with the offering and sale of the Notes.

The Notes and the Guarantees attached thereto are herein collectively referred to as the “Securities.”

The Securities are being offered and sold by the Issuers in connection with the acquisition by the Company (the “Acquisition”) of Arizona Chemical Holdings Corporation, a Delaware corporation (“Arizona”), pursuant to a Stock Purchase Agreement dated as of September 27, 2015 (together with all exhibits, schedules and disclosure letters thereto, collectively, as may be amended, the “Acquisition Agreement”) among the Company, Arizona and AZC Holding Company LLC, a Delaware limited liability company, pursuant to which the Company agreed to purchase all of the outstanding capital stock of Arizona. Immediately following the consummation of the Acquisition, Arizona and any additional entities required to guarantee the Securities pursuant to the Indenture (collectively, the “Additional Guarantors”) will be joined as parties to this Agreement pursuant to a joinder agreement, the form of which is attached hereto as Annex II (the “Joinder Agreement”). The proceeds from this offering will be used to pay tender premiums with respect to the tender offer and consent solicitation (the “Tender Offer”) for the Issuers’ 6.75% Senior Notes due 2019 (the “Existing Notes”), to pay a portion of the cash purchase price of the Acquisition and to pay related fees and expenses, as described under the caption “Use of Proceeds” in the Offering Circular (as defined below).

As used herein, the term “Transactions” means collectively, (i) the offer and sale of the Securities, (ii) the consummation of the Acquisition, (iii) the entry by the Issuers and the Guarantors into the New Senior Secured Credit Facilities and the initial extensions of credit thereunder, if any, on the Closing Date, (iv) the Tender Offer, (v) the Redemption, (vi) the repayment of certain borrowings under the Company’s existing credit facilities as described in the Offering Circular and (vii) the payment of transaction costs (which may be paid after the Closing Date).

Additionally, at any time when the Parent is not subject to Section 13 or 15 of the Exchange Act, for the benefit of holders and beneficial owners from time to time of the Securities, the Parent shall furnish, at its expense, upon request, to holders and beneficial owners of Securities and prospective purchasers of Securities information satisfying the requirements of Rule 144A(d).

(j) No Integration. Each of the Issuers agrees that it will not and will cause its Affiliates not to make any offer or sale of securities of the Issuers of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render invalid (for the purpose of (i) the sale of the Securities by the Issuers to the Initial Purchasers, (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by such Subsequent Purchasers to others) the exemption from the registration requirements of the Securities Act provided by Section 4(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise.

(k) No General Solicitation or Directed Selling Efforts. The Company agrees that it will not and will not permit any of its Affiliates or any other person acting on its or their behalf (other than the Initial Purchasers, as to which no covenant is given) to (i) solicit offers for, or offer or sell, the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(2) of the Securities Act or (ii) engage in any directed selling efforts with respect to the Securities within the meaning of Regulation S, and the Company will and will cause all such persons to comply with the offering restrictions requirement of Regulation S with respect to the Securities.

Each of the Issuers and the Guarantors, jointly and severally, agrees to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act against any loss, claim, damage, liability or expense, as incurred, to which such Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under Section 15 of the Securities Act, Section 20 of the Exchange Act or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Issuers), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Additional Written Communication or the Offering Circular (or any amendment or supplement thereto (including, for the avoidance of doubt, any Updated Offering Circular as defined in Section 10 hereof)), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and to reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by such Initial Purchaser or such affiliate, director, officer, employee or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply, with respect to an Initial Purchaser, to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Issuers by any Initial Purchaser through the Representatives expressly for use in any Issuer Additional Written Communication or the Offering Circular (or any amendment or supplement thereto (including, for the avoidance of doubt, any Updated Offering Circular as defined in Section 10 hereof)). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Issuers may otherwise have.

(b) Indemnification of the Issuers and the Guarantors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Issuers, each Guarantor, each of their respective directors, officers and employees, and each person, if any, who controls the Issuers or any Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which the Issuers, any Guarantor or any such director, officer and employee, or controlling person may become subject, under Section 15 of the Securities Act, Section 20 of the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Initial Purchaser), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in any Issuer Additional Written Communication or the Offering Circular (or any amendment or supplement thereto (including, for the avoidance of doubt, any Updated Offering Circular as defined in Section 10 hereof)), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Issuer Additional Written Communication or the Offering Circular (or any amendment or supplement thereto (including, for the avoidance of doubt, any Updated Offering Circular as defined in Section 10 hereof)), in reliance upon and in conformity with written information furnished to the Issuers by any Initial Purchaser through the Representatives expressly for use therein; and to reimburse the Issuers, any Guarantor and each such director, officer and employee, or controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are reasonably incurred by the Issuers, any Guarantor or such director, officer or employee, or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Issuers and the Guarantors hereby acknowledges that the only information that the Initial Purchasers through the Representatives have furnished to the Issuers expressly for use any Issuer Additional Written Communication or the Offering Circular (or any amendment or supplement thereto (including, for the avoidance of doubt, any Updated Offering Circular as defined in Section 10 hereof)) are the statements set forth in the ninth and tenth paragraphs and the third and fourth sentences of the seventh paragraph under the caption “Plan of Distribution” in the Offering Circular. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under Section 8(a) or Section 8(b), notify the indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under Section 8(a) or Section 8(b) except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an indemnified party other than under Section 8(a)

or Section 8(b). In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under Section 8(a) or Section 8(b) for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)), which shall be selected by the Representatives (in the case of counsel representing the Initial Purchasers or their related persons), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which will not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Issuers, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Issuers and the Guarantors, on the one hand, or the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 8 hereof for purposes of indemnification.

The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 9.

Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be required to contribute any amount in excess of the discount received by such Initial Purchaser in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of Section 11 of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to

contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A hereto. For purposes of this Section 9, each director, officer and employee of an Initial Purchaser and each person, if any, who controls an Initial Purchaser within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director officer and employee of the Issuers or any Guarantor, and each person, if any, who controls the Issuers or any Guarantor with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Issuers and the Guarantors.

(g) if, at any time prior to completion of the resale of all the Securities by the Initial Purchasers (as determined by one or more Initial Purchasers holding a majority of the outstanding Securities then held by the Initial Purchasers), any event occurs or information becomes known that, in the reasonable judgment of the Issuers or any of the Guarantors or in the opinion of counsel for the Initial Purchasers, should be set forth in the Offering Circular or any Updated Offering Circular, so that Offering Circular or any Updated Offering Circular, as then amended or supplemented, does not include any untrue statement of material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to amend or supplement the Offering Circular or any Updated Offering Circular in order to comply with any law, the Issuers and the Guarantors will forthwith prepare an appropriate amendment or supplement thereto, and will expeditiously furnish to the Initial Purchasers and dealers a reasonable number of copies thereof.

11. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Issuers if at any time: (i) trading or quotation in any of the Issuers’ or any Guarantor’s securities shall have been suspended or limited by the Commission or by the NYSE, or trading in securities generally on either the Nasdaq Stock Market or the NYSE shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any such quotation system or stock exchange by the Commission or the Financial Industry Regulatory Authority, Inc.; (ii) a general banking moratorium shall have been declared by any of federal or New York or Delaware authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the U.S. or international financial markets, or any substantial change or development involving a prospective substantial change in U.S. or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities in the manner and on the terms described in the Offering Circular or to enforce contracts for the sale of securities; or (iv) in the judgment of the Representatives, there shall have occurred any change, or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, properties or prospects of the Parent and its subsidiaries taken as a whole which, is material and adverse and makes it impractical or inadvisable to proceed with the offering or delivery of the Securities on the terms and in the manner contemplated in the Offering Circular. Any termination pursuant to this Section 11 shall be without liability on the part of (i) the Issuers or any Guarantor to any Initial Purchaser, except that the Issuers and the Guarantors shall be obligated to reimburse the expenses of the Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any Initial Purchaser to the Issuers, or (iii) any party hereto to any other party except that the provisions of Sections 8 and 9 hereof shall at all times be effective and shall survive such termination.

Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court.

19. Default of One or More of the Several Initial Purchasers. If any one or more of the several Initial Purchasers shall fail or refuse to purchase the Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the proportions that the number of the Securities set forth opposite their respective names on Schedule A hereto bears to the aggregate number of the Securities set forth opposite the names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the Securities which such defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the aggregate number of the Securities with respect to which such default occurs exceeds 10% of the aggregate number of the Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Issuers for the purchase of such Securities are not made within 48 hours after

such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. In any such case either the Initial Purchasers or the Issuers shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Offering Circular or any other documents or arrangements may be effected.

As used in this Agreement, the term “Initial Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 19. Any action taken under this Section 19 shall not relieve any defaulting Initial Purchaser from liability in respect of any default of such Initial Purchaser under this Agreement.

20. No Advisory or Fiduciary Responsibility. Each of the Issuers and the Guarantors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Issuers and the Guarantors, on the one hand, and the several Initial Purchasers, on the other hand, and the Issuers and the Guarantors are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Initial Purchaser is and has been acting solely as a principal and is not the agent or fiduciary of the Issuers, the Guarantors or their respective affiliates, stockholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility in favor of the Issuers and the Guarantors with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Issuers and the Guarantors on other matters) or any other obligation to the Issuers and the Guarantors except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Issuers and the Guarantors, and the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby, and the Issuers and the Guarantors have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

The Company and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that the Issuers and the Guarantors may have against the several Initial Purchasers with respect to any breach or alleged breach of fiduciary duty.

Such Initial Purchaser agrees that it has not offered or sold and will not offer or sell the Securities in the United States or to, or for the benefit or account of, a U.S. Person (other than a distributor), in each case, as defined in Rule 902 of Regulation S (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering of the Securities pursuant hereto and the Closing Date, other than in accordance with Regulation S or another exemption from the registration requirements of the Securities Act. Such Initial Purchaser agrees that, during such 40-day restricted period, it will not cause any advertisement with respect to the Securities (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any public place and will not issue any circular relating to the Securities, except such advertisements as are permitted by and include the statements required by Regulation S.

Such Initial Purchaser agrees that, at or prior to confirmation of a sale of Securities by it to any distributor, dealer or person receiving a selling concession, fee or other remuneration during the 40-day restricted period referred to in Rule 903 of Regulation S, it will send to such distributor, dealer or person receiving a selling concession, fee or other remuneration a confirmation or notice to substantially the following effect:
