 Exhibit 10.17 

ADVANCED DRAINAGE SYSTEMS, INC. 

INDEMNIFICATION AGREEMENT 

(Directors and Officers) 

THIS INDEMNIFICATION AGREEMENT (this “Agreement”) is entered into as of
                    , by and between ADVANCED DRAINAGE SYSTEMS, INC., a Delaware corporation (“ADS”), and
                    , an individual (“Indemnitee”). 

Background 

WHEREAS, it is essential to ADS to retain and attract the most capable persons available to serve as directors and senior officers; and 

WHEREAS, Indemnitee is a director and/or senior officer of ADS; and 

WHEREAS, both ADS and Indemnitee recognize the increased risk of litigation and other claims being asserted against directors and senior
officers of corporations in today’s environment; and 
 WHEREAS, in recognition of Indemnitee’s need for substantial protection
against personal liability in order to enhance Indemnitee’s continued service to ADS in an effective manner, ADS wishes to provide in this Agreement for the indemnification of and the advancing of expenses to Indemnitee to the full extent
(whether partial or complete) permitted by law and as set forth in this Agreement, and, to the extent insurance is maintained, for the continued coverage of Indemnitee under ADS’ directors’ and officers’ liability insurance policies.

 NOW, THEREFORE, in consideration of the premises and of Indemnitee continuing to serve ADS directly or, at its request, with another
enterprise, and intending to be legally bound hereby, the parties hereto agree as follows: 
 1. Agreement to Indemnify. ADS hereby
agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law. In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

(a) Proceedings Other Than Proceedings by or in the Right of ADS. Indemnitee shall be entitled to the rights of
indemnification provided in this Section l(a) if, by reason of his Corporate Status (as defined in Section 12), the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as defined in
Section 12) other than a Proceeding by or in the right of ADS. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as defined in Section 12), judgments, penalties, fines and
amounts paid in settlement actually and reasonably incurred by him, or on his behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed
to be in or not opposed to the best interests of ADS, and with respect to any criminal Proceeding, had no reasonable cause to believe the Indemnitee’s conduct was unlawful. 







 (b) Proceedings by or in the Right of ADS. Indemnitee shall be entitled to
the rights of indemnification provided in this Section 1(b) if, by reason of his Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of ADS. Pursuant to
this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee acted in good faith and
in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of ADS; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect of any claim, issue or matter in
such Proceeding as to which Indemnitee shall have been adjudged to be liable to ADS unless and to the extent that the Court of Chancery of the State of Delaware, or the court in which such Proceeding was brought, shall determine that such
indemnification may be made. 
 (c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the maximum extent
permitted by law against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but
less than all claims, issues or matters in such Proceeding, ADS shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with each successfully resolved claim, issue or matter. For
purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

2. Additional Indemnity. In addition to, and without regard to any limitations on, the indemnification provided for in
Section 1 of this Agreement, ADS shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by him or on his behalf if,
by reason of his Corporate Status, he is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of ADS), including, without limitation, all liability arising out of the negligence or
active or passive wrongdoing of Indemnitee. 
 3. Contribution. 

(a) Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any
threatened, pending or completed action, suit or proceeding in which ADS is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), ADS shall pay, in the first instance, the entire amount of any judgment or
settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and ADS hereby waives and relinquishes any right of contribution it may have against Indemnitee. ADS shall not enter into any settlement of any
action, suit or proceeding in which ADS is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

  
 - 2 - 








 (b) Without diminishing or impairing the obligations of ADS set forth in the
preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which ADS is jointly liable with
Indemnitee (or would be if joined in such action, suit or proceeding), ADS shall contribute to the amount of expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or
payable by Indemnitee in proportion to the relative benefits received by ADS and all officers, directors or employees of ADS, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding),
on the one hand, and Indemnitee, on the other hand, from the transaction from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to
law, be further adjusted by reference to the relative fault of ADS and all officers, directors or employees of ADS other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one
hand, and Indemnitee, on the other hand, in connection with the events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which the Law may require to be considered. The relative
fault of ADS and all officers, directors or employees of ADS, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, shall be
determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is
active or passive. 
 (c) ADS hereby agrees to fully indemnify and hold Indemnitee harmless from any claims of contribution
which may be brought by officers, directors or employees of ADS, other than Indemnitee, who may be jointly liable with Indemnitee. 

(d) To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is
unavailable to Indemnitee for any reason whatsoever, ADS, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement
and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the
relative benefits received by ADS and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of ADS (and its directors, officers, employees and agents) and Indemnitee in
connection with such event(s) and/or transaction(s). 
 4. Indemnification for Expenses of a Witness. Notwithstanding any other
provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, he shall be indemnified against all Expenses actually and reasonably incurred by him or
on his behalf in connection therewith. 
 5. Advancement of Expenses. Notwithstanding any other provision of this Agreement, ADS
shall advance all Expenses incurred by or on behalf of Indemnitee in 

  
 - 3 - 








 
connection with any Proceeding by reason of Indemnitee’s Corporate Status within five (5) business days after the receipt by ADS of a statement or statements from Indemnitee requesting
such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by Indemnitee and shall include or be preceded or accompanied by
an undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such Expenses. ADS acknowledges and agrees that an undertaking in
substantially the form attached hereto as Exhibit A shall be sufficient for purposes of this Section 5. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. The
right to advancement of expenses provided for in this Section 5 is a separate and distinct right and is not dependent upon a determination that Indemnitee is entitled to indemnification under this Agreement or otherwise. 

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for
Indemnitee rights of indemnity that are as favorable as may be permitted under the Delaware General Corporation Law and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply
in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 
 (a) To obtain
indemnification under this Agreement, Indemnitee shall submit to ADS a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and
to what extent Indemnitee is entitled to indemnification. The Secretary of ADS shall, promptly upon receipt of such a request for indemnification, advise the Board of Directors in writing that Indemnitee has requested indemnification. 

(b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of Section 6(a) hereof, a
determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following three methods which, provided there has not been a Change in Control since the effective
date of this Agreement, shall be at the election of the board: (1) by a majority vote of the Disinterested Directors (as defined in Section 12), even though less than a quorum, by a committee of Disinterested Directors designated by
a majority vote of the Disinterested Directors, even though less than a quorum, (2) if there are no Disinterested Directors or if the Disinterested Directors so direct, by independent legal counsel in a written opinion to the Board of
Directors, a copy of which shall be delivered to the Indemnitee, or (3) if so directed by the Board of Directors, by the stockholders of ADS. If there has been a Change in Control since the effective date of this Agreement, the determination
shall be made by independent legal counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to the Indemnitee. 

(c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to
Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board of Directors. Indemnitee may, within 10 days after such written notice of
selection shall have been given, deliver to ADS, as the case may be, a written objection to such selection; provided, however, that such objection may be asserted only on the 

  
 - 4 - 








 
ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 12 of this Agreement, and the objection
shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected
may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after submission by Indemnitee of a written request for indemnification pursuant to
Section 6(a) hereof, no Independent Counsel shall have been selected and not objected to, either ADS or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any
objection which shall have been made by the Indemnitee to ADS’ selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the
person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 6(b) hereof. ADS shall pay any and all reasonable fees and expenses of Independent Counsel incurred by
such Independent Counsel in connection with acting pursuant to Section 6(b) hereof, and ADS shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such
Independent Counsel was selected or appointed. 
 (d) In making a determination with respect to entitlement to
indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and
the burden of persuasion by clear and convincing evidence. Neither the failure of ADS (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that
indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by ADS (including by its directors or independent legal counsel) that Indemnitee has not met such applicable
standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of
account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise (as defined in Section 12) in the course of their duties, or on the advice of legal counsel for the
Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or
actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of
this Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of ADS. Anyone seeking to
overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

  
 - 5 - 








 (f) If the person, persons or entity empowered or selected under
Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by ADS of the request therefor, the requisite determination of entitlement to
indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s
statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not
to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or
information relating thereto; and provided, further, that the foregoing provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is to be made by the stockholders pursuant to
Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by ADS of the request for such determination, the Board of Directors or the Disinterested Directors, if appropriate, resolve to submit such
determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of stockholders is called
within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat. 

(g) Indemnitee shall cooperate with the person, persons or entity making such determination with respect to Indemnitee’s
entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably available
to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board of Directors or stockholder of ADS shall act reasonably and in good faith in making a determination regarding the Indemnitee’s
entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by ADS
(irrespective of the determination as to Indemnitee’s entitlement to indemnification) and ADS hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) ADS acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to
avoid expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without
limitation, settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone
seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

  
 - 6 - 








 (i) The termination of any Proceeding or of any claim, issue or matter therein,
by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a
presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of ADS or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that
his conduct was unlawful. 
 7. Remedies of Indemnitee. 

(a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to indemnification is made pursuant to
Section 6(b) of this Agreement within 90 days after receipt by ADS of the request for indemnification, (iv) payment of indemnification is not made pursuant to this Agreement within ten (10) days after receipt by ADS of a
written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to indemnification or such determination is deemed to have been made pursuant to
Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification.
Indemnitee shall commence such proceeding seeking an adjudication within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 7(a). ADS shall not oppose
Indemnitee’s right to seek any such adjudication. 
 (b) In the event that a determination shall have been made pursuant
to Section 6(b) of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial on the merits, and
Indemnitee shall not be prejudiced by reason of the adverse determination under Section 6(b). 
 (c) If a
determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, ADS shall be bound by such determination in any judicial proceeding commenced pursuant to this
Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for
indemnification, or (ii) a prohibition of such indemnification under applicable law. 
 (d) In the event that
Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of his rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies
maintained by ADS, ADS shall pay on his behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 12 of this Agreement) actually and reasonably incurred by him in such judicial
adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery. 

  
 - 7 - 








 (e) ADS shall be precluded from asserting in any judicial proceeding commenced
pursuant to this Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that ADS is bound by all the provisions of this Agreement. ADS shall indemnify
Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by ADS of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are
incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from ADS under this Agreement or under any directors’ and officers’ liability insurance policies maintained by ADS,
regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under
this Agreement shall be required to be made prior to the final disposition of the Proceeding. 
 8. Non-Exclusivity; Survival of Rights;
Insurance; Subrogation. 
 (a) The rights of indemnification as provided by this Agreement shall not be deemed exclusive
of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation or Bylaws of ADS, any agreement, a vote of stockholders, a resolution of directors or otherwise. No amendment, alteration or
repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his Corporate Status prior to such amendment, alteration or
repeal. To the extent that a change in the Delaware General Corporation Law, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Bylaws and this Agreement, it is the intent of the
parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other right or remedy. 
 (b) To the extent that ADS maintains an insurance policy or policies
providing liability insurance for directors, officers, employees, or agents or fiduciaries of ADS or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person serves at the request of
ADS, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary under such policy or policies for so long as
Indemnitee may be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of his Corporate Status, whether or not he is acting or serving in any such capacity at the time any liability or expense is
incurred. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, ADS has director and officer liability insurance in effect, ADS shall give prompt notice of the commencement of such proceeding to the insurers in
accordance 

  
 - 8 - 








 
with the procedures set forth in the respective policies. ADS shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts
payable as a result of such proceeding in accordance with the terms of such policies. 
 (c) ADS hereby acknowledges that
Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance provided by Indemnitee’s employer and/or ADS stockholder that designated or otherwise caused Indemnitee to serve in his Corporate Status
(collectively, the “Other Indemnitors”). ADS hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Other Indemnitors to advance expenses or to
provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all
Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of Incorporation or Bylaws of ADS (or any other agreement between ADS and
Indemnitee), without regard to any rights Indemnitee may have against the Other Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases the Other Indemnitors from any and all claims against the Other Indemnitors for
contribution, subrogation or any other recovery of any kind in respect thereof. ADS further agrees that no advancement or payment by the Other Indemnitors on behalf of Indemnitee with respect to any claim for which Indemnitee has sought
indemnification from ADS shall affect the foregoing and the Other Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee against ADS. ADS and
Indemnitee agree that the Other Indemnitors are express third party beneficiaries of the terms of this Section 8(c). 

(d) In the event of any payment under this Agreement, ADS shall be subrogated to the extent of such payment to all of the
rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable ADS to bring suit to enforce such rights. 

(e) ADS shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the
extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(f) ADS’ obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of ADS
as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of
expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

  
 - 9 - 








 9. Exceptions to Right of Indemnification. Notwithstanding any provision in this
Agreement, ADS shall not be obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 

(a) where it is finally determined that indemnification (under the procedures, and subject to the presumptions, set forth in
Sections 6 and 7 hereof) is unlawful; 
 (b) for which payment has actually been made to or on behalf of
Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or 

(c) for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of ADS
within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar provisions of state statutory law or common law; or 

(d) in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any
part of any Proceeding) initiated by Indemnitee against ADS or its directors, officers, employees or other indemnitees, unless (i) the Board of Directors of ADS authorized the Proceeding (or any part of any Proceeding) prior to its initiation
or (ii) ADS provides the indemnification, in its sole discretion, pursuant to the powers vested in ADS under applicable law or (iii) the Proceeding is brought by Indemnitee for the purpose of enforcing his or her rights under this
Agreement or Indemnitee’s rights to indemnification or advancement of expenses under the Certificate of Incorporation or Bylaws of ADS, applicable law or otherwise. 

10. Duration of Agreement. All agreements and obligations of ADS contained herein shall continue during the period Indemnitee is an
officer or director of ADS (or is or was serving at the request of ADS as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and shall continue thereafter so long as Indemnitee shall
be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of his Corporate Status, whether or not he is acting or serving in any such capacity at the time any liability or expense is incurred for which
indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase,
merger, consolidation or otherwise to all or substantially all of the business or assets of ADS), assigns, spouses, heirs, executors and personal and legal representatives. 

11. Enforcement. 

(a) ADS expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it hereby
in order to induce Indemnitee to continue to serve as an officer or director of ADS, and ADS acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of ADS. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and
supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof.

 12. Definitions. For purposes of this Agreement: 

(a) “Change in Control” means the occurrence of a transaction or series of transactions following which less

(b) “Corporate Status” describes the status of a person who is or was a director, officer, employee, agent or

(c) “Disinterested Director” means a director of ADS who is not and was not a party to the Proceeding in
respect of which indemnification is sought by Indemnitee. 
 (d) “Enterprise” shall mean ADS and any other
corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that Indemnitee is or was serving at the express written request of ADS as a director, officer, employee, agent or fiduciary. 

(e) “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs,

upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered hereunder. The failure to so
