(c) Release of Collateral Shares upon Conversion, Redemption or Put of Preferred. Pledgor may, upon three (3) Business Days’ notice (or four (4) Business Days if such notice is not received by 12:00 noon on the applicable Business Day) to the Collateral Agent and the applicable Optionee (a “CR Release Notice”), request the release of Collateral Shares from the Optionee Collateral Account of an Optionee contemporaneous with (i) such Optionee’s election to convert all or a portion of the Rentech Preferred Shares owned by it into Rentech Common Shares in accordance with the terms of the Articles of Amendment to the Rentech Organizational Documents, (ii) such Optionee’s election to redeem all or a portion of the Rentech Preferred Shares owned by such Optionee in accordance with the terms of the Articles of Amendment to the Rentech Organizational Documents or (iii) such Optionee’s election to require Rentech, Inc. to purchase all or a portion of the Rentech Preferred Shares owned by

such Optionee in accordance with the terms of the Subscription Agreement, and in each case, upon such Optionee’s direction and upon the receipt by the Collateral Agent of evidence satisfactory to it that such conversion, redemption or purchase has been consummated, Collateral Agent shall instruct Custodian to release such Collateral Shares on the date specified by Pledgor in such request. Pledgor’s CR Release Notice shall specify (1) the name of the applicable Optionee, (2) the number of Rentech Preferred Shares that are being converted, redeemed or purchased at or about the time the CR Release Notice has been delivered and (3) the number of Collateral Shares requested to be released from the Optionee Collateral Account of such Optionee. The number of Collateral Shares to be released will be determined by the Pledgor using the following formulas (which calculations will be specified in such notice and certified to the Collateral Agent): (A) if the Collateral Shares Price determined by the Pledgor as of the release date specified by Pledgor in such CR Release Notice is greater than the Collateral Shares Price determined by the Pledgor as of the date of this Agreement, then the number of Collateral Shares to be released shall be the result of (which shall be deemed to be zero if it is a negative number) (I) the aggregate Redemption Price of the Rentech Preferred Shares of such Optionee that are being converted to Rentech Common Shares or redeemed or purchased at such time divided by (II) the Collateral Shares Price determined by the Pledgor as of the date of this Agreement or (B) if the Collateral Shares Price determined by the Pledgor as of the release date specified by Pledgor in such CR Release Notice is equal to or less than the Collateral Shares Price determined by the Pledgor as of the date of this Agreement, then the number of Collateral Shares to be released shall be (I) the total number of Collateral Shares pledged as Collateral for the benefit of such Optionee pursuant to this Agreement at such time less (II) the quotient of (aa) the aggregate Redemption Price for the Rentech Preferred Shares of such Optionee then outstanding less the aggregate Redemption Price for the Rentech Preferred Shares of such Optionee that are being converted to Rentech Common Shares or redeemed or purchased at such time, divided by (bb) the Collateral Shares Price determined by the Pledgor as of the release date specified by Pledgor in such Conversion Release Notice.

(d) Release of Collateral Shares upon Repurchase of Preferred. Pledgor may, upon three (3) Business Days’ notice (or four (4) Business Days if such notice is not received by 12:00 noon on the applicable Business Day) to the Collateral Agent and the applicable Optionee (a “Repurchase Release Notice”), request the release of all of the Collateral Shares from the Optionee Collateral Account of an Optionee contemporaneous with Rentech, Inc.’s election to (i) redeem all of the Rentech Preferred Shares owned by such Optionee in accordance with the terms of the Articles of Amendment to the Rentech Organizational Documents or (ii) repurchase all of such Optionee’s Rentech Preferred Shares in accordance with the Subscription Agreement, and in each case, upon such Optionee’s direction and upon the receipt by the Collateral Agent of evidence satisfactory to it that such redemption or repurchase has been consummated, Collateral Agent shall instruct Custodian to release such Collateral Shares on the date specified by Pledgor in such request. Pledgor’s Repurchase Release Notice shall specify the name of the applicable Optionee.

(e) Adjustment to Number of Collateral Shares to be Released. The calculations used to determine the number of Collateral Shares to be released pursuant to Section 4(b) or Section 4(c) above shall be adjusted to reflect events occurring after the date of this Agreement affecting either the Rentech Preferred Shares or the Collateral Shares that are of the type referred to in Section 5(d), 5(e), 5(f), 5(g) or 5(h) in the Articles of Amendment to the Rentech Organizational Documents creating the Rentech Preferred Shares.

(f) Termination of Optionee Put Option Agreement. If any Optionee Put Option Agreement terminates in accordance with its terms (other than by reason of an assignment permitted pursuant to Section 9 thereof) then all Rentech Preferred Shares credited to the respective Optionee Collateral Account shall be automatically released hereunder.

with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the name of Pledgor or in its own name, to take after the occurrence and during the continuance of an Event of Default and from time to time thereafter, any and all action and to execute any and all documents and instruments which the Collateral Agent at any time and from time to time deems necessary or desirable to accomplish the purposes of this Agreement, including, without limitation, selling any of the Collateral on behalf of Pledgor as agent or attorney in fact for Pledgor and receiving, evidencing and collecting all checks and other orders for the payment of money made payable to Pledgor with respect to the Collateral and applying the proceeds received therefrom to pay the applicable Optionee Put Obligations in accordance with the applicable Optionee Put Option Agreement; however, nothing in this paragraph shall be construed to obligate the Collateral Agent to take any action hereunder nor shall the Collateral Agent or any Optionee be liable to Pledgor for failure to take any action hereunder. This appointment shall be deemed a power coupled with an interest, is irrevocable.

8. Rights and Powers of the Collateral Agent. The Collateral Agent, after the occurrence and during the continuance of an Event of Default, without liability to Pledgor, may (at the direction of the applicable Optionee): take control of proceeds, including stock received as dividends or by reason of stock splits; release the applicable Optionee Collateral in its possession to Pledgor, temporarily or otherwise; reject as unsatisfactory any property hereafter offered by Pledgor as Optionee Collateral; take control of funds generated by the applicable Optionee Collateral, such as cash dividends, interest and proceeds, and use same to reduce the applicable Optionee Put Obligations; exercise all other rights which an owner of such Optionee Collateral may exercise; and at any time transfer any of the applicable Optionee Collateral or evidence thereof into its own name or that of its nominee. Neither the Collateral Agent, any Optionee, nor any of such Person’s Related Parties shall be liable for failure to collect any account or instruments, or for any act or omission on the part of the Collateral Agent, its officers, agents or employees, except for any act or omission arising out of their own willful misconduct or fraud as determined by a court of competent jurisdiction in a final non-appealable judgment. The foregoing rights and powers of the Collateral Agent and the Optionees will be in addition to, and not a limitation upon, any rights and powers of the Collateral Agent and the Optionees, as applicable, given by Law, elsewhere in this Agreement, or otherwise.

9. Default.

(a) Rights and Remedies. After the occurrence and during the continuance of an Event of Default and at any time thereafter, the Collateral Agent at the written direction of the applicable Optionee shall, without (i) presentment, demand, or protest, (ii) notice of default, dishonor, demand, non-payment, or protest, or (iii) notice of any other kind, all of which Pledgor hereby expressly waives (except for any notice required under such Optionee’s Put Option Agreement or which may not be waived under applicable Law), exercise and enforce, any and all of the rights and remedies provided hereunder or available to the Collateral Agent at law or in equity, including, without limitation, the following rights and remedies:

(i) Exercise of Exclusive Control. The Collateral Agent shall exercise exclusive control over such Optionee Collateral Account and the Optionee Collateral held or deposited therein.

(ii) Control of Collateral. The Collateral Agent shall, without liability to Pledgor, take control of the proceeds, including stock received as dividends or by reason of stock splits, temporarily or otherwise, take control of funds generated by the applicable Optionee Collateral,

including the applicable Optionee Collateral Account, such as cash dividends, interest and proceeds, and use same to reduce any part of the applicable Optionee Put Obligations and exercise all other rights which an owner of such Collateral may exercise, and at any time transfer any of such Collateral or evidence thereof into its own name or that of its nominee.

(iii) Liquidation and Redemption of Collateral. The Collateral Agent shall instruct a Custodian to cancel any open trade, settlement, transfer or other orders with respect to any of the applicable Optionee Collateral, redeem any of such Optionee Collateral by notice to the issuer of such Optionee Collateral, transfer any or all of such Optionee Collateral to the Collateral Agent or its designee, transfer the whole or any part of such Optionee Collateral into its name or the name of its nominee or to notify the obligors on any such Optionee Collateral to make payment to the Collateral Agent or its nominee of any amounts due thereon and to take control or grant its nominee the right to take control of any proceeds of such Optionee Collateral, liquidate or redeem such Optionee Collateral under its name or under the name of Pledgor pursuant to Section 7, withdraw and/or sell any such Optionee Collateral and pay the proceeds of any such Optionee Collateral to the applicable Optionee for application by such Optionee to the its unpaid Optionee Put Obligations.

(iv) Uniform Commercial Code. In addition, as directed by the applicable Optionee in writing, the Collateral Agent shall exercise or enforce all of the rights, powers and remedies of a secured creditor under the Uniform Commercial Code (“UCC”) as the same may, from time to time, be in effect in the State of New York, including any rights under Section 9-607 of the UCC, provided, however, in any event that, by reason of mandatory provisions of Law, any or all of the attachment, perfection or priority (or terms of similar import in any applicable jurisdiction) of the Collateral Agent’s Lien on any portion of the applicable Optionee Collateral is governed by the Uniform Commercial Code (or other similar Law) as in effect in a jurisdiction (whether within or outside the United States) other than the State of New York, the term “UCC” shall mean the Uniform Commercial Code (or other similar Law) as in effect in such other jurisdiction for purposes of the provisions hereof relating to such attachment, perfection or priority (or terms of similar import in such jurisdiction) and for purposes of definitions related to such provisions, and any and all rights and remedies available to it hereunder.

(b) Foreclosure Sales

(i) Pledgor specifically understands and agrees that any sale by the Collateral Agent of all or part of the Collateral pursuant to the terms of this Agreement may be effected by the Collateral Agent at times and in manners which could result in the proceeds of such sale as being significantly and materially less than what might have been received if such sale had occurred at different times or in different manners, and Pledgor hereby releases the Collateral Agent, the Optionees and their officers and representatives and Related Parties from and against any and all obligations and liabilities arising out of or related to the timing or manner of any such sale. If, in the opinion of the Collateral Agent, there is any question that a public sale or distribution of any Collateral will violate any state or federal securities law, the Collateral Agent may offer and sell such Collateral in a transaction exempt from registration under federal securities law, and any such sale made in good faith by the Collateral Agent shall be deemed “commercially reasonable.” Furthermore, Pledgor acknowledges that any such restricted or private sales may be at prices and on terms less favorable to Pledgor than those obtainable through a public sale without such restrictions, but agrees that such sales are commercially reasonable. Pledgor further acknowledges that any specific disclaimer of any warranty of title or the like by the Collateral Agent will not be considered to adversely affect the commercial reasonableness of any sale of Collateral.

(ii) Subject to clause (c) below and to the extent a notice of a sale is required to be given by the Collateral Agent under 9-611 of the UCC, any notice made shall be deemed reasonable if sent to Pledgor at the address referred to in Section 10(d) prior to (x) the date of any proposed public sale of any Collateral Shares (or on such date but prior to any such sale) or (y) the date on or after which the Collateral Agent intends to conduct a private sale of any Collateral Shares (or on such date but prior to any such sale), and any such period shall constitute a reasonable time for such notice. The Collateral Agent retains all rights to suspend or delay any such sales with or without notice.

(iii) Neither the Collateral Agent, any Optionee or any of such Person’s Related Parties shall be liable for failure to collect any account or instruments, or for any act or omission on the part of such Person, its officers, agents or employees in connection with the Collateral, including any action or omission that occurs during the exercise of the Collateral Agent’s rights or remedies, except for any act or omission determined by a court of competent jurisdiction in a final, non-appealable judgment to constitute gross negligence or willful misconduct on the part of such Person.

(iv) Pledgor shall be liable for any deficiency if the proceeds of any sale or other disposition of any Optionee Collateral are insufficient to pay the Optionee Put Obligations (including the fees and disbursements of counsel employed by the Collateral Agent to collect such deficiency).

(c) Sales of Collateral Shares. Without limiting the foregoing clauses (a) and (b), Pledgor agrees that the Collateral Shares are of a kind that is customarily sold on a recognized market.

10. General.

(a) Parties Bound. The Collateral Agent’s rights hereunder shall inure to the benefit of the Optionees and their respective successors and assigns, and the Optionee’s rights hereunder shall inure to the benefit of their respective successors and assigns. All representations, warranties and agreements of Pledgor shall be binding upon the personal representatives, heirs, successors and assigns of Pledgor.

(b) Waiver. No failure by or delay of the Collateral Agent or any Optionee in exercising any power, right or remedy shall operate as a waiver thereof; nor shall any single or partial exercise of any power, right or remedy preclude other or further exercise thereof or the exercise of any other power, right or remedy. Each right, power and remedy of the Collateral Agent and any Optionee as provided for herein, or which shall now or hereafter exist at law or in equity or by statute or otherwise, shall be cumulative and concurrent and shall be in addition to every other such right, power or remedy. The exercise or beginning of the exercise by the Collateral Agent or any Optionee of any one or more of such rights, powers or remedies shall not preclude the simultaneous or later exercise by the Collateral Agent or such Optionee of any or all other such rights, powers or remedies.

(c) Continuing Agreement. This Agreement shall constitute a continuing agreement and shall continue in effect until the date all Put Option Agreements have been terminated in

accordance with their terms and all then existing obligations of Pledgor thereunder have been paid in full, provided that an Optionee shall have no further rights or obligations under this Agreement after the earlier of (x) the date such Optionee’s Put Option Agreement terminates in accordance with its terms and (y) the first date after such Optionee has exercised its Put Right under its Optionee Put Option Agreement and receives payment in full of the amount required to be paid thereunder.

Exhibit A

Agency Provisions

Section 1. Appointment and Authority. Each of the Optionees hereby irrevocably appoints Credit Suisse AG, Cayman Islands Branch to act on its behalf as Collateral Agent hereunder and authorizes Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to Collateral Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto. In performing its functions and duties hereunder, Collateral Agent shall act solely as an agent of the Optionees and does not assume and shall not be deemed to have assumed any obligation towards or relationship of agency or trust with or for Pledgor. Upon request of Collateral Agent, each Optionee agrees to promptly provide Collateral Agent with such information related to an Optionee Collateral Account or any Collateral subject to the control of such Optionee. The provisions of this Article are solely for the benefit of the Optionees, and the Pledgor shall have no rights as a third party beneficiary of any of such provisions.

Section 2. Rights as an Optionee. If the Person serving as Collateral Agent hereunder also acts as a Optionee hereunder, it shall have the same rights and powers in its capacity as a Optionee as any other Optionee and may exercise the same as though it were not Collateral Agent and the term “Optionee” or “Optionees” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as Collateral Agent hereunder in its individual capacity. Collateral Agent and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with Pledgor or other Affiliate (including Issuer) thereof as if such Person were not Collateral Agent hereunder and without any duty to account therefor to the Optionees.

Section 3. Exculpatory Provisions.

(a) Collateral Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, Collateral Agent:

(i)

shall not be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing;

(ii)

shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that Collateral Agent is required to exercise, provided that Collateral Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose Collateral Agent to liability or that is contrary to this Agreement or applicable Law; or

(iii)

shall not, except as expressly set forth herein, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to Pledgor or any of its Affiliates (including Issuer) that is communicated to or obtained by the Person serving as Collateral Agent or any of its Affiliates in any capacity.

Neither Collateral Agent nor any of its Related Parties shall be liable for any action taken or not taken by it (i) with the consent or at the request of any Optionee (or such other number or percentage of the Optionees as shall be necessary, or as Collateral Agent shall believe in good faith shall be necessary) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a final, nonappealable judgment of a court of competent jurisdiction. Collateral Agent shall not be deemed to have knowledge of any Event of Default unless and until written notice describing such Event of Default is given to Collateral Agent by Pledgor or an Optionee.

Collateral Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms, conditions, or provisions set forth herein, or as to the existence or possible existence of any Event of Default, or (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document.

Section 4. Reliance by Collateral Agent. Collateral Agent shall be entitled to rely upon, shall be fully protected in relying on and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. Collateral Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. Collateral Agent may consult with legal counsel (who may be counsel for Pledgor), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Section 5. Delegation of Duties. Collateral Agent, without consent of or notice to any party hereto, may perform any and all of its duties and exercise its rights and powers hereunder by or through any one or more agents, sub-agents, affiliates or employees appointed by Collateral Agent. Collateral Agent and any such agents, sub-agent, affiliates or employees may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Exhibit shall apply to any such agents, sub-agents, affiliates or employees and to the Related Parties of Collateral Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facility provided for herein as well as activities as Collateral Agent.

Section 6. Resignation of Collateral Agent. Collateral Agent may at any time give notice of its resignation to Optionees and Pledgor. Upon receipt of any such notice of resignation, the Required Optionees shall have the right, in consultation with (and so long as no Event of Default then exists, with approval of) Pledgor, to appoint a successor Collateral Agent. If no such successor shall have been so appointed by the Required Optionees or an appointed successor does not accept such appointment within thirty (30) days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may on behalf of the Optionees, appoint a successor Collateral Agent, provided that if Collateral Agent shall notify Pledgor and

Optionees that no Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (a) the retiring Collateral Agent shall be discharged from its duties and obligations hereunder (except that if any Collateral is then held by Collateral Agent hereunder, the retiring Collateral Agent shall continue to hold such Collateral until such time as a successor Collateral Agent is appointed) and (b) all payments, communications and determinations provided to be made by, to or through Collateral Agent shall instead be made by or to each Optionee directly, until such time as Required Optionees appoint a successor Collateral Agent as provided for above in this Section, and the retiring Collateral Agent shall take such actions as may be necessary or appropriate to transfer all Collateral held by it to the successor Collateral Agent. Upon the acceptance of a successor’s appointment as Collateral Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Collateral Agent, and the retiring Collateral Agent shall be discharged from all of its duties and obligations hereunder (if not already discharged therefrom as provided above in this Section). After the retiring Collateral Agent’s resignation hereunder, the provisions of this Exhibit shall continue in effect for the benefit of such retiring Collateral Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Collateral Agent was acting as Collateral Agent.

Section 7. Non-Reliance on Collateral Agent and Other Optionees. Each Optionee acknowledges that it has, independently and without reliance upon Collateral Agent or any other Optionee or any of their Related Parties and based on such documents and information as it has deemed appropriate, performed its own analysis and made its own decision (credit, legal and otherwise) to enter into this Agreement or any related agreement or any document furnished hereunder. Each Optionee also acknowledges that it will, independently and without reliance upon Collateral Agent or any other Optionee or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to perform its own analysis and make its own decisions (credit, legal and otherwise) in taking or not taking action under or based upon this Agreement or any related agreement or any document furnished hereunder or thereunder.

Section 8. No Other Duties. Anything herein to the contrary notwithstanding, Collateral Agent shall not have any powers, duties or responsibilities under this Agreement, except in its capacity as Collateral Agent hereunder.

Section 9. Costs and Expenses; Indemnification; Damage Waiver.

(a) Costs and Expenses. Pledgor shall pay (i) all reasonable out-of-pocket expenses incurred by Collateral Agent, any Optionee and their respective Affiliates after the date of this Agreement (including the reasonable fees, charges and disbursements of counsel) in connection with the administration of this Agreement and the preparation, negotiation, execution, delivery of any amendments, modifications or waivers of the provisions hereof or thereof, and (ii) all out-of-pocket expenses incurred by Collateral Agent or any Optionee (including the fees, charges and disbursements of any counsel for Collateral Agent and any Optionee), in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section, and including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of this Agreement or any Put Option Agreement.

(b) Indemnification by Pledgor. Pledgor shall indemnify Collateral Agent (and any sub-agent thereof), each Optionee and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the fees, charges and disbursements of one counsel to Collateral Agent and its Related Parties and one counsel for the other Indemnitees (and, if reasonably necessary, one local counsel to Collateral Agent and its Related Parties and one local counsel to the other Indemnitees, in any relevant material jurisdiction)) incurred by any Indemnitee or asserted against any Indemnitee by any third party or by Pledgor or any Related Party of Pledgor arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, or the administration of this Agreement or (ii) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by Pledgor or any Related Party of Pledgor, and regardless of whether any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted primarily from the gross negligence or willful misconduct of such Indemnitee.

(c) Reimbursement by Optionees. To the extent that Pledgor for any reason fails to indefeasibly pay any amount required under subsection (a) or (b) of this Section 9 to be paid by it to Collateral Agent (or any sub-agent thereof) or any Related Party of any of the foregoing, each Optionee severally agrees to pay to Collateral Agent (or any such sub-agent) or such Related Party, as the case may be, such Optionee’s ratable share (determined based on the ratio of (x) the number of Rentech Preferred Shares held by such Optionee at such time to (y) the aggregate number of Rentech Preferred Shares outstanding at such time) of such unpaid amount, provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against Collateral Agent (or any such sub-agent) in its capacity as such, or against any Related Party of any of the foregoing acting for Collateral Agent (or any such sub-agent) in connection with such capacity.

(d) Waiver of Consequential Damages, Etc. To the fullest extent permitted by applicable Law, Pledgor shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby. No Indemnitee referred to in subsection (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the transactions contemplated hereby or thereby.

(e) Payments. All amounts due under this Section 9 shall be payable not later than ten (10) Business Days after demand therefor.

(f) Survival. The agreements in this Section shall survive the resignation or replacement of Collateral Agent, the replacement of any Optionee, the termination of any Put Option Agreement and the repayment, satisfaction or discharge of the Aggregate Put Obligations.
