(iii) Any failure to assert any breach of or default under any of the Financing Document, any of the Senior Secured Obligations or the Intercreditor Agreement; any extensions of credit in excess of the amount committed under or contemplated by any of the Financing Documents, or in circumstances in which any condition to such extensions of credit has not been satisfied; any other exercise or non-exercise, or any other failure, omission, breach, default, delay, or wrongful action in connection with any exercise or non-exercise, of any right or remedy against such Pledgor or any other Person under or in connection with any of the Financing Document, any of the Senior Secured Obligations, or the Intercreditor Agreement; any refusal of payment or performance of any of the Senior Secured Obligations, whether or not with any reservation of rights against any Pledgor; or any application of collections (including collections resulting from realization upon any direct or indirect security for the Senior Secured Obligations) to other obligations, if any, not entitled to the benefits of this Agreement, in preference to the Senior Secured Obligations or, if any collections are applied to the Senior Secured Obligations, any application to particular Senior Secured Obligations;

(iv) Any taking, exchange, amendment, modification, supplement, termination, subordination, release, loss, or impairment of, or any failure to protect, perfect, or preserve the value of, or any enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or any failure, omission, breach, default, delay, or wrongful action by the Collateral Agent or any other Person in connection with the enforcement of, realization upon, or exercise of rights or remedies under or in connection with, or, any other action or inaction by Collateral Agent or any other Person in respect

of, any direct or indirect security for any of the Senior Secured Obligations (including the Pledged Collateral). As used in this Agreement, “direct or indirect security” for the Senior Secured Obligations, and similar phrases, includes any collateral security, guaranty, suretyship, letter of credit, capital maintenance agreement, put option, subordination agreement, or other right or arrangement of any nature providing direct or indirect assurance of payment or performance of any of the Senior Secured Obligations, made by or on behalf of any Person;

(vi) Any defense, setoff, or counterclaim which may at any time be available to or be asserted by any Pledgor, the Mexican Borrower, ADS Corporativo or any other Person with respect to any of the Financing Documents, any of the Senior Secured Obligations or the Intercreditor Agreement; or any discharge by operation of law or release of any Pledgor, the Mexican Borrower, ADS Corporativo or any other Person from the performance or observance of any of the Financing Documents, any of the Senior Secured Obligations or the Intercreditor Agreement; or

(vii) Any other event or circumstance, whether similar or dissimilar to the foregoing, and whether known or unknown, which might otherwise constitute a defense available to, or limit the liability of a guarantor or a surety, including any Pledgor, excepting only performance and Payment In Full of the Senior Secured Obligations.

11. No Waiver; Cumulative Remedies.

No failure to exercise, and no delay in exercising, on the part of the Collateral Agent, any right, power or privilege hereunder shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder preclude any further exercise thereof or the exercise of any other right, power or privilege. No waiver of a single Event of Default shall be deemed a waiver of a subsequent Event of Default. The remedies herein provided are cumulative and not exclusive of any remedies provided under the other Financing Documents, the Intercreditor Agreement or by law, rule or regulation and the Collateral Agent may enforce any one or more remedies hereunder successively or concurrently at its option. Each Pledgor waives any right to require the Collateral Agent to proceed against any other Person or to exhaust any of the Pledged Collateral or other security for the Senior Secured Obligations or to pursue any remedy in the Collateral Agent’s power.

12. Waivers.

Each Pledgor hereby waives any and all defenses that any Pledgor may now or hereafter have based on principles of suretyship, impairment of collateral, or the like and each Pledgor hereby waives any defense to or limitation on its obligations under this Agreement. Without limiting the generality of the foregoing and to the fullest extent permitted by applicable law, each Pledgor hereby further waives each of the following:

(a) All notices, disclosures and demands of any nature that otherwise might be required from time to time to preserve intact any rights against such Pledgor, including the following: any notice of any event or circumstance described in the immediately preceding Section hereof; any notice required by any law, regulation or order now or hereafter in effect in any jurisdiction; any notice of nonpayment, nonperformance, dishonor or protest under any of the Financing Documents, any of the Senior Secured Obligations or the Intercreditor Agreement; any notice of the incurrence of any Senior Secured Obligations; any notice of any default or any failure on the part of such Pledgor, the Mexican Borrower, ADS Corporativo or any other Person to comply with any of the Financing Documents, any of the Senior Secured Obligations or the Intercreditor Agreement, or any requirement pertaining to any direct or indirect security for any of the Senior Secured Obligations; and any notice or other information pertaining to the business, operations, condition (financial or otherwise), or prospects of the Borrower, the Mexican Borrower, ADS Corporativo or any other Person;

(b) Any right to any marshalling of assets, to the filing of any claim against such Pledgor, the Mexican Borrower, ADS Corporativo or any other Person in the event of any bankruptcy, insolvency, reorganization, or similar proceeding, or to the exercise against such Pledgor, the Mexican Borrower, ADS Corporativo or any other Person of any other right or remedy under or in connection with any of the Financing Documents, any of the Senior Secured Obligations or the Intercreditor Agreement, or any direct or indirect security for any of the Senior Secured Obligations; any requirement of promptness or diligence on the part of the Collateral Agent or any other Person; any requirement to exhaust any remedies under or in connection with, or to mitigate the damages resulting from default under, any of the Financing Documents, any of the Senior Secured Obligations or the Intercreditor Agreement, or any direct or indirect security for any of the Senior Secured Obligations; any benefit of any statute of limitations; and any requirement of acceptance of this Agreement or any of the other Financing Documents or the Intercreditor Agreement, and any requirement that any Pledgor receive notice of any such acceptance; and

(c) Any defense or other right arising by reason of any law now or hereafter in effect in any jurisdiction pertaining to election of remedies (including anti-deficiency laws, “one action” laws, or the like), or by reason of any election of remedies or other action or inaction by the Collateral Agent (including commencement or completion of any judicial proceeding or nonjudicial sale or other action in respect of collateral security for any of the Senior Secured Obligations), which results in denial or impairment of the right of the Collateral Agent to seek a deficiency against the Borrower, the Mexican Borrower, ADS Corporativo or any other Person or which otherwise discharges or impairs any of the Senior Secured Obligations.

13. Taxes.

(a) [Intentionally omitted].

(b) Without limiting anything contained in any of the Financing Documents or the Intercreditor Agreement, each Pledgor acknowledges that the Pledged Collateral secures payment of all present and future stamp or documentary taxes and any other excise or property taxes, charges, or similar levies which arise from any payment or collection made hereunder or from the execution, delivery, or registration of, or otherwise with respect to, this Agreement (hereinafter referred to as “Other Taxes”).

(c) Each Pledgor acknowledges that the Pledged Collateral secures the full amount of Other Taxes (including any Other Taxes imposed by any jurisdiction on amounts payable under this Section) paid by the Collateral Agent and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto, whether or not such Other Taxes were correctly or legally asserted.

(d) As soon as practicable after the payment of Other Taxes by any Pledgor to a Governmental Authority, such Pledgor shall furnish to the Collateral Agent, the original or a certified copy of a receipt evidencing payment thereof.

(e) Without prejudice to the survival of any other agreement of any Pledgor hereunder, the agreements and obligations of each Pledgor contained in clauses (a) through (d) directly above shall survive Payment In Full.

14. Judgment Currency.

(a) If for the purposes of obtaining judgment in any court it is necessary to convert a sum due under this Agreement in any currency (the “Original Currency”) into another currency (the “Other Currency”), each Pledgor hereby agrees, to the fullest extent permitted by law, that the rate of exchange used shall be that at which in accordance with normal banking procedures the Collateral Agent could purchase the Original Currency with the Other Currency after any premium and costs of exchange on the Business Day preceding that on which final judgment is given.

(b) The obligation of each Pledgor in respect of any sum due from such Pledgor to the Collateral Agent under this Agreement shall, notwithstanding any judgment in an Other Currency, whether pursuant to a judgment or otherwise, be discharged only to the extent that, on the business day (being a day on which the Collateral Agent is open for business at its principal office) following receipt by the Collateral Agent of any sum adjudged to be so due in such Other Currency, the Collateral Agent may in accordance with normal banking procedures purchase the Original Currency with such Other Currency. If the amount of the Original Currency so purchased is less than the sum originally due to the Collateral Agent in the Original Currency, such Pledgor agrees, as a separate obligation and notwithstanding any such judgment or payment, that Pledged Collateral secures payment to the Collateral Agent to indemnify it against such loss.

15. Waiver of Sovereign Immunity.

To the extent that any Pledgor has or hereafter may acquire any immunity from the jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution, or otherwise) with respect to itself or its property, such Pledgor hereby irrevocably waives such immunity in respect of its obligations under this Agreement and any other document or agreement executed or given in connection therewith, and such Pledgor agrees that it will not raise or claim any such immunity at or in respect of any such action or proceeding.

16. Assignment.

All rights of the Collateral Agent under this Agreement shall inure to the benefit of its successors and assigns. All obligations of each Pledgor shall bind its successors and assigns; provided, however, each Pledgor may not assign or transfer any of its rights and obligations hereunder or any interest herein, and any such purported assignment or transfer shall be null and void.

17. Severability.

Any provision (or portion thereof) of this Agreement which shall be held invalid or unenforceable shall be ineffective without invalidating the remaining provisions hereof or portions thereof.

18. Governing Law.

This Agreement shall be deemed to be a contract under the laws of the State of Ohio and shall for all purposes be governed by and construed and enforced in accordance with the laws of the State of Ohio without regard to its conflicts of laws principles, except to the extent of any provision of the Code that applies the law of the jurisdiction in which the Pledged Collateral is located; provided, however, that in no event shall this Section be applied or interpreted to defeat a perfected security interest in the Pledged Collateral that would be valid under an otherwise applicable law.

19. Notices.

All notices, requests, demands, directions and other communications (collectively, “notices”) given to or made upon any party hereto under the provisions of this Agreement shall be given or made as set forth in Section 11.5 [Notices; Effectiveness; Electronic Communication] of the Domestic Credit Agreement in the case of the Pledgors and as set forth in Section 7.9 [Notices] of the Intercreditor Agreement in the case of the Collateral Agent.

20. Specific Performance.

Each Pledgor acknowledges and agrees that, in addition to the other rights of the Collateral Agent hereunder, under the other Financing Documents and under the Intercreditor Agreement, because the Collateral Agent’s remedies at law for failure of such Pledgor to comply with the provisions hereof relating to the Collateral Agent’s rights (i) to inspect the books and

records related to the Pledged Collateral, (ii) to receive the various notifications such Pledgor is required to deliver hereunder, (iii) to obtain copies of agreements and documents as provided herein with respect to the Pledged Collateral, (iv) to enforce the provisions hereof pursuant to which such Pledgor has appointed the Collateral Agent its attorney-in-fact, and (v) to enforce the Collateral Agent’s remedies hereunder, would be inadequate and that any such failure would not be adequately compensable in damages, such Pledgor agrees that each such provision hereof may be specifically enforced.

21. Voting Rights in Respect of the Pledged Collateral.

So long as no Event of Default shall occur and be continuing under any of the Financing Documents, each Pledgor may exercise any and all voting and other consensual rights pertaining to the Pledged Collateral or any part thereof for any purpose not inconsistent with the terms of this Agreement, the other Financing Documents or the Intercreditor Agreement; provided, however, that such Pledgor will not exercise or will refrain from exercising any such voting and other consensual right pertaining to the Pledged Collateral, as the case may be, if such action would impair any Pledged Collateral. At any time and from time to time, after and during the continuation of an Event of Default, no Pledgor shall be permitted to exercise any of its respective voting and other consensual rights whatsoever pertaining to the Pledged Collateral or any part thereof; provided, however, in addition to the other rights with respect to the Pledged Collateral granted to the Collateral Agent and the Secured Parties hereunder, at any time and from time to time, after and during the continuation of an Event of Default, the Collateral Agent may exercise any and all voting and other consensual rights of each and every Pledgor pertaining to the Pledged Collateral or any part thereof. Without limiting the generality of the foregoing and in addition thereto, without the written consent of the Collateral Agent, the Pledgors shall not vote to enable, or take any other action to permit, any of the Companies to issue any stock, member interests, partnership interests or other equity securities, member interests, partnership interests or other ownership interests of any nature or to issue any other securities, shares, capital stock, member interests, partnership interests or other ownership interests convertible into or granting the right to purchase or exchange for any stock, member interests, partnership interests or other equity securities, member interests, partnership interests or other ownership interests of any nature of any such Company, unless all such additional stock, member interests, partnership interests, or other equity securities shall be Pledged Collateral subject to the terms of this Agreement. The Pledgors shall not enter into any agreement or undertaking restricting the right or ability of the Pledgor or the Collateral Agent to sell, assign or transfer any of the Pledged Collateral.

22. Consent to Jurisdiction.

Each Pledgor and each of the Companies hereby irrevocably submits to the nonexclusive jurisdiction of any U.S. federal or Ohio state court sitting in Franklin County, Ohio, in any action or proceeding arising out of or relating to this Agreement, and Pledgors and each of the Companies hereby irrevocably agree that all claims in respect of such action or proceeding may be heard and determined in such Ohio state or federal court. Each Pledgor and each of the Companies hereby waives to the fullest extent it may effectively do so, the defense of an inconvenient forum to the maintenance of any such action or proceeding. Each Pledgor and each of the Companies hereby appoints the process agent identified below (the “Process Agent”) as its

agent to receive on behalf of such party and its respective property service of copies of the summons and complaint and any other process which may be served in any action or proceeding. Such service may be made by mailing or delivering a copy of such process to any of the Pledgors or the Companies in care of the Process Agent at the Process Agent’s address, and each of the Pledgors and the Companies hereby authorizes and directs the Process Agent to receive such service on its behalf. Each Pledgor and each of the Companies agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions (or any political subdivision thereof) by suit on the judgment or in any other manner provided by law. Each Pledgor and each of the Companies further agrees that it shall, for so long as any Commitment or any obligation of any Loan Party to any Secured Party remains outstanding, continue to retain Process Agent for the purposes set forth in this Section. The Process Agent is Advanced Drainage Systems, Inc., a Delaware corporation, with an office on the date hereof at 0000 Xxxxxxx Xxxxxxxxx, Xxxxxxxx, Xxxx 00000, Xxxxxx Xxxxxx of America. Each Pledgor and each of the Companies shall produce to the Collateral Agent evidence of the acceptance by Process Agent of such appointment.

23. Waiver of Jury Trial.

EXCEPT AS PROHIBITED BY LAW, EACH PLEDGOR, EACH OF THE COMPANIES AND THE COLLATERAL AGENT, ON BEHALF OF THE SECURED PARTIES, HEREBY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY A JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER DOCUMENTS OR TRANSACTIONS RELATING THERETO.

24. Entire Agreement; Amendments.

(a) This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements relating to a grant of a security interest in the Pledged Collateral by any Pledgor to the Collateral Agent but solely to the extent irreconcilably inconsistent with this Agreement.

(b) Except as expressly provided in Section 5(g) with respect to additions to Schedule A hereto, as updated from time to time in accordance with the terms of this Agreement, and in Section 9 with respect to additional Pledgors, this Agreement may not be amended or supplemented except by a writing signed by the Collateral Agent and the Pledgors.

25. Counterparts; Telecopy Signatures.

This Agreement may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which, when so executed, shall be deemed an original, but all such counterparts shall constitute one and the same instrument. Each Pledgor acknowledges and agrees that a telecopy or other electronic transmission to the Collateral Agent or any Secured Party of the signature pages hereof purporting to be signed on behalf of any Pledgor shall constitute effective and binding execution and delivery hereof by such Pledgor.

26. Descriptive Headings.

The descriptive headings which are used in this Agreement are for the convenience of the parties only and shall not affect the meaning of any provision of this Agreement.

27. Amendment and Restatement; No Novation. This Agreement hereby amends and restates, in its entirety, the existing Pledge Agreement, dated as of September 24, 2010 (the “Existing Pledge Agreement”), by and among the parties thereto, and the parties hereto agree and acknowledge that this Agreement is not intended to constitute, nor does it constitute, an interruption, suspension of continuity, satisfaction, discharge of prior duties, novation, or termination of the Liens, security interests, indebtedness, loans, liabilities, expenses, or obligations under the Existing Pledge Agreement or under the Credit Agreement or any of the other Loan Documents (except in each case as expressly modified in accordance with the Credit Agreement and the other Loan Documents amended in connection therewith). Notwithstanding the foregoing, pledgors which were party to the Existing Pledge Agreement but which are not parties to this Agreement are hereby released from the Exiting Pledge Agreement and all collateral pledged by each such pledgor not a party to this Agreement is hereby released.
