Computershare shall not be obligated to pay such interest, dividends or earnings to Company, any holder or any other party.

Exhibit (k)(9) - Form of Subscription Agent Agreement.DOCX |  | Page 5

6.2 The Rights shall be issued in registered, book-entry form only. Agent shall keep books and records of the registration, transfer and exchange of the Rights (the “Rights Register”).

6.3 All of the Rights issued upon any registration of transfer or exchange of the Rights shall be the valid obligations of Company, evidencing the same obligations and entitled to the same benefits under this Agreement as the Rights surrendered for such registration of transfer or exchange; provided, that until such transfer or exchange is registered in the Rights Register, Company and Agent may treat the registered holder thereof as the owner for all purposes.

6.4 For so long as this Agreement shall be in effect, Company will reserve for issuance and keep available free from preemptive rights a sufficient number of shares of the Additional Common Stock to permit the exercise in full of all of the Rights issued pursuant to the Subscription Offer.

6.5 Company shall take any and all action, including, without limitation, obtaining the authorization, consent, lack of objection, registration or approval of any governmental authority, or the taking of any other action under the laws of the United States of America or any political subdivision thereof, to insure that all of the shares of the Additional Common Stock issuable upon the exercise of the Rights (subject to payment of the Subscription Price) will be validly issued, fully paid and non-assessable shares of the Common Stock, free from all preemptive rights and taxes, liens, charges and security interests created by or imposed upon Company with respect thereto.

7. Procedure for Discrepancies

Agent shall follow its regular procedures to attempt to reconcile any discrepancies between the number of shares of Additional Common Stock that any Subscription Form may indicate are to be issued to a stockholder upon the exercise of the Rights and the number that the Record Stockholders List indicates may be issued to such stockholder. In any instance where Agent cannot reconcile such discrepancies by following such procedures, Agent will consult with Company for instructions as to the number of shares of Additional Common Stock, if any, Agent is authorized to issue. In the absence of such instructions, Agent is authorized not to issue any shares of Additional Common Stock to such stockholder and will return to the subscribing stockholder (at Agent’s option by either first class mail under a blanket surety bond or insurance protecting Agent and Company from losses or liabilities arising out of the non-receipt or non-delivery of the Subscription Form or by registered mail insured separately for the value of the applicable Rights) to such stockholder’s address as set forth in the Subscription Form, any Subscription Form delivered to Agent, any other documents delivered therewith and a letter explaining the reason for the return of such documents.

8. Procedure for Deficient Items

8.1 Agent shall examine the Subscription Form(s) received by it as agent to ascertain whether they appear to have been completed and executed in accordance with the Subscription Offer. In the event that Agent determines that any Subscription Form does not appear to have been properly completed or executed, or to be in proper form, or any other deficiency in connection with the Subscription Form appears to exist, Agent shall follow, where possible, its regular procedures to attempt to cause such irregularity to be corrected. Agent is not authorized to waive any deficiency in connection with the Subscription, unless Company provides written authorization to waive such deficiency.

Exhibit (k)(9) - Form of Subscription Agent Agreement.DOCX |  | Page 6

8.2 If a Subscription Form specifies that shares of the Additional Common Stock are to be issued to a person other than the person in whose name a surrendered Right is registered, Agent will not issue such shares until such Subscription Form has been properly endorsed with the signature guaranteed in a manner acceptable to Agent (or otherwise put in proper form for transfer).

8.3 If any such deficiency is neither corrected nor waived, Agent will return to the subscribing stockholder (at Agent’s option by either first class mail under a blanket surety bond or insurance protecting Agent and Company from losses or liabilities arising out of the non-receipt or non-delivery of the Subscription Form or by registered mail insured separately for the value of the applicable Rights) to such stockholder’s address as set forth in the Subscription Form, any Subscription Form delivered to Agent, any other documents delivered therewith and a letter explaining the reason for the return of such documents.

9. Tax Reporting

9.1 Agent shall prepare and file with the appropriate governmental agency and mail to each stockholder, as applicable, all appropriate tax information forms, including, but not limited to, Forms 1099-B, covering payments or any other distributions made by Agent pursuant to this Agreement during each calendar year, or any portion thereof, during which Agent performs services hereunder, as described in the attached Exhibit A. Any cost basis or tax adjustments required after the Effective Time will incur additional fees.

9.2 With respect to any surrendering stockholder whose TIN has not been certified as correct, Agent shall deduct and withhold the appropriate backup withholding tax from any payment made to such stockholder pursuant to the Internal Revenue Code.

9.3 Should any issue arise regarding federal income tax reporting or withholding, Agent shall take such reasonable action as Company may reasonably request in writing. Such action may be subject to additional fees.

10. Unresponsive Payees; Unclaimed Property After the eight month anniversary of the Effective Time, for the purpose of locating unresponsive payees of checks representing any uncashed payments resulting from this Subscription Offer, Agent may use the services of a stockholder locating and/or asset reunification service provider selected by Agent, which may be an affiliate of Agent (“Service Provider”), to facilitate the location of and/or contact of holders who have not yet cashed their checks representing overpayment of subscription application funds. Such Service Provider may compensate Agent for processing and other services Agent provides in connection with such services, including providing Agent a portion of its fees. Such Service Provider shall inform any such located and/or contacted stockholders that they may choose either (i) to contact Agent directly to receive a check for payment at no charge other than any applicable fees contemplated by this Agreement or (ii) to utilize the services of such Service Provider for a fee, which may not exceed the lesser of 20% of the total value of such stockholder’s uncashed payment or the maximum statutory fee permitted by the applicable state jurisdiction. If the Company selects a locating and/or asset reunification service provider other than one selected by Agent, then Agent shall not be responsible for the terms of any agreement with such provider and additional fees may apply.

The Company hereby authorizes and instructs Agent to provide to Service Provider on behalf of Computershare or Company pursuant to this Section 10:

(i) aggregate data of stockholders who have not cashed their checks representing return of funds related to the Subscription Offer and Company information, including number of accounts, value of Uncashed checks, effective date and type of transaction, second mailing date (if applicable), and information concerning this Section 10, in order for the Service Provider to determine the feasibility of providing locating and/or asset reunification services; and

(2) preliminary escheatment files of stockholders with uncashed checks (used to block accounts that may not be serviced under the program based on state unclaimed property laws); and

15. Confidentiality

15.1 Definition. “Confidential Information” shall mean any and all technical or business information relating to a party, including, without limitation, financial, marketing and product development information, stockholder data (including any non-public information of such stockholder), proprietary information, and the terms and conditions (but not the existence) of this Agreement, that is disclosed or otherwise becomes known to the other party or its affiliates, agents or representatives before or during the term of this Agreement. Confidential Information constitutes trade secrets and is of great value to the owner (or its affiliates). Confidential Information shall not include any information that is: (a) already known to the other party or its affiliates at the time of the disclosure; (b) publicly known at the time of the disclosure or

Exhibit (k)(9) - Form of Subscription Agent Agreement.DOCX |  | Page 10

15.2 Use and Disclosure. All Confidential Information of a party will be held in confidence by the other party with at least the same degree of care as such party protects its own confidential or proprietary information of like kind and import, but not less than a reasonable degree of care. No party will disclose in any manner Confidential Information of the other party in any form to any person or entity without the other party’s prior consent. However, each party may disclose relevant aspects of the other party’s Confidential Information to its officers, affiliates, agents, subcontractors and employees to the extent reasonably necessary to perform its duties and obligations under this Agreement and such disclosure is not prohibited by applicable law. Without limiting the foregoing, each party will implement physical and other security measures and controls designed to protect (a) the security and confidentiality of Confidential Information; (b) against any threats or hazards to the security and integrity of Confidential Information; and (c) against any unauthorized access to or use of Confidential Information. To the extent that a party delegates any duties and responsibilities under this Agreement to an agent or other subcontractor, the party ensures that such agent and subcontractor are contractually bound to confidentiality terms consistent with the terms of this Section 15.

15.3 Required or Permitted Disclosure. In the event that any requests or demands are made for the disclosure of Confidential Information, other than requests to Agent for stockholder records pursuant to standard subpoenas from state or federal government authorities (e.g., divorce and criminal actions), the party receiving such request will promptly notify the other party to secure instructions from an authorized officer of such party as to such request and to enable the other party the opportunity to obtain a protective order or other confidential treatment, unless such notification is otherwise prohibited by law or court order. Each party expressly reserves the right, however, to disclose Confidential Information to any person whenever it is advised by counsel that it may be held liable for the failure to disclose such Confidential Information or if required by law or court order.

15.4 Unauthorized Disclosure. As may be required by law and without limiting any party’s rights in respect of a breach of this Section 15, each party will promptly:

| (a) | Notify the other party in writing of any unauthorized possession, use or disclosure of the other party’s Confidential Information by any person or entity that may become known to such party;

| (b) | Furnish to the other party full details of the unauthorized possession, use or disclosure; and

| (c) | Use commercially reasonable efforts to prevent a recurrence of any such unauthorized possession, use or disclosure of Confidential Information.

15.5 Costs. Each party will bear the costs it incurs as a result of compliance with this Section 15.

16. Compensation and Expenses

16.1 Advisor shall pay to Agent compensation in accordance with the fee schedule attached as Exhibit B hereto, together with reimbursement for reasonable fees and disbursements of counsel, regardless of whether any Rights are surrendered to Agent, for Agent’s services hereunder.

Such charges include, but are not limited to, stationery and supplies, such as checks, envelopes and paper stock, as well as any disbursements for telephone and document creation and delivery.

Year End Tax Reporting Package

Computershare cannot provide tax advice for purposes of completing this worksheet. Please consult your tax counsel to determine your respective tax reporting requirements.

Stockholder accounts without certified TIN, or certification of foreign status on our system of record will be subject to backup withholding tax at the applicable rate in accordance with IRS rules and regulations regarding 1099 tax reporting. The applicable backup withholding tax deducted from their payment will be remitted to the Internal Revenue Service (IRS). Holders will need to claim any refund of over withholding directly from the IRS and not Computershare. Please note residents or holders that are uncertified, and reside in the state of CA will be withheld an additional 7% which will be remitted to the state of CA.

Important: Computershare uses Constructive Receipt (refer to below definition) reporting for its standard tax reporting default. Deviations from our Standard Default Tax Terms, late submissions and subsequent corrections after the event is over will be subject to additional fees, by appraisal. If Computershare does not receive the completed tax letter by the expiration of the offer /effective date of the distribution or exchange, Computershare will use our Standard Default Tax Terms.

Computershare will perform form suppression on de minimis reporting for the following: on 1099-B tax forms less than $20 in proceeds and fractional share issuance if no withholding; 1099-DIV tax forms less than $10 in dividend income if no withholding.

Computershare will not be liable for any IRS penalties resulting from any client changes to this tax letter or client delay in any final tax instructions that will alter our initial tax reporting instructions. Should any withholding be remitted late to the IRS as a result of any changes to your initial tax reporting instructions. Company and/or Purchaser will be responsible for obligations related to penalties and interest as noted under the Section of the Agreement titled “Indemnification and Limitation of Liability.”

Definitions:

Constructive Receipt: Constructive Receipt means that any corporate action exchange proceeds would be reported to the IRS in the year the merger is effective, whether or not the stockholder has presented the requisite and valid documentation in such year.

Standard Default Tax Terms: The share consideration (if any) is considered a non-taxable event with no Fair Market Value Reporting (FMV) on shares. Principal and CIL are reported on form 1099B as constructive receipt. In the event of an exchange, dividends declared after the effective date, will accrue on the shares issuable to un-exchanged holders and tax reported “as if” paid currently.
