 WHEREAS, in connection with the Original Override Agreement, the Counterparties and TMA entered into that certain Security Agreement, dated April 1,

 WHEREAS, the Counterparties, TMI, TMHS, TMHL and the Manager desire to amend and restate the Original
Override Agreement as set forth below, so that the terms of the Original Override Agreement will, on and as of the date hereof, be amended and restated as described herein: 
 NOW, THEREFORE, in consideration of the premises and mutual obligations set forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, each Counterparty, severally and not jointly, and TMA and the Manager agree that the Original Override Agreement shall be, and it hereby is, amended and restated to read in its entirety as follows:

 SECTION 1. This Agreement shall have a term and shall be terminable as follows: 
 (a) Override Period. This Agreement shall be effective through March 15, 2009 (the period prior to the expiration or
termination of this Agreement being referred to herein as the “Override Period”), unless earlier rescinded, replaced or modified by all parties hereto in writing or terminated by TMA and the Counterparties in accordance with
Section 1(b) or by any Counterparty with respect to itself in accordance with Section 1(c); provided that in the event of a termination by a Counterparty in accordance with Section 1(c), the Override Period with respect to such
Counterparty shall be deemed to terminate upon the occurrence of such termination. 
 (b) Termination by TMA. TMA may
terminate this Agreement at any time by written notice to the Counterparties; provided that such termination by TMA must be with respect to all Counterparties at the same time and provided, further, that TMA may terminate this
Agreement in accordance with this Section 1(b) only if all Counterparties have consented in writing to such termination or each Counterparty has confirmed in writing (which confirmation will not be unreasonably withheld or delayed) that
(i) TMA has fully paid to such Counterparty (x) all outstanding interest or price differentials payable under the corresponding Financing Agreements and this Agreement, (y) all outstanding reasonable legal fees incurred by such
Counterparty and (z) without duplication, each “Repurchase Price”, return of cash collateral in connection with a securities loan, and other applicable outstanding payment, margin, mark-to-market deficiency or other payment or
repayment obligation provided under the corresponding Financing Agreements, including without limitation any obligations of TMA relating to deficiency amounts in connection with Auction Swaps which have previously had their call dates (clauses (x),
(y) and (z), collectively, the “Payment Obligations”) and (ii) the related transactions have been terminated (clauses (i) and (ii), collectively, the “Compliance Requirements”). For the avoidance of
doubt, the Counterparties acknowledge that, with regard to any deficiency amounts relating to Auction Swaps which have previously had their call dates, the principal amount of such deficiency amounts shall be fixed as of the related call date.

 (c) Termination by Counterparties. Upon written notice to TMA and the other Counterparties (except in the case of an
event described in clause (ii) or (iii) below, in which case this Agreement shall terminate automatically), any Counterparty may terminate this Agreement with respect to itself (except as otherwise stated in clause (vi) below) in any
of the following circumstances (an “Override Termination Event”): 
 (i) TMA fails to pay any amount that it
has agreed to pay (x) under Section 3(i) or (y) pursuant to any irrevocable instructions or consents it has given to account banks in connection with any Collateral Payments (as defined below) that TMA receives from the Counterparties
and agrees or has agreed to repay to the Counterparties; provided that no such failure resulting solely from administrative error or operational difficulties at such an account bank shall constitute an Override Termination Event unless it
continues for more than one business day; 
  

 -2- 








 (ii) any of TMI, TMHL, TMHS or the Manager voluntarily becomes a debtor in a proceeding
under the Bankruptcy Code; 
 (iii) any of TMI, TMHL, TMHS or the Manager involuntarily becomes a debtor in a proceeding under
the Bankruptcy Code and the proceeding is not dismissed within 15 business days; 
 (iv) TMA breaches any of its covenants
contained herein (other than in Section 3(i)), in the Security Agreement or in the Control Agreement, and any such breach is not cured within ten business days after receipt by TMA of written notice thereof from any Counterparty, or withdraws
or attempts to withdraw any irrevocable instructions or consents it has given with respect to any payments with respect to Collateral; 
 (v) there is a Change in Control (as defined below in Section 17), other than one arising from the issuance of shares of common stock to, or from another recapitalization transaction with, the investors in the
“Financing Transaction” described in TMI’s Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2008 or the holders of TMI’s 8.00% Senior Notes due 2013, or from the “Exchange Offer and Consent
Solicitation” described in TMI’s Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2008; 
 (vi) any Counterparty breaches Section 2(b) and serves a notice of termination of, or terminates any transactions under, its corresponding Financing Agreements, or exercises remedies in respect of such Financing Agreements, and TMA
does not obtain relief enjoining such Counterparty (the “Breaching Counterparty”) from such termination or exercise of remedies by the close of business on the fourth full business day following the date of the earliest to occur of
such Counterparty’s (x) service of a notice of termination or (y) termination or (z) exercise of remedies, in each case, in respect of the relevant Financing Agreement; provided, however, that no Override Termination Event
shall occur under this clause (c)(vi) with respect to the Breaching Counterparty, and any failure of TMA to obtain injunctive relief against the Breaching Counterparty shall not in any manner impair any rights or claims that TMA may have against the
Breaching Counterparty in relation to such breach; or 
 (vii) the expiration of this Agreement pursuant to Section 1(a)
if the Compliance Requirements as to all Counterparties are not satisfied. 
  

 -3- 








 (d) In the event of expiration of this Agreement pursuant to Section 1(a) or
termination of this Agreement pursuant to Section 1(b) or clause (ii) or (iii) of Section 1(c), such expiration or termination shall become effective simultaneously with respect to all parties hereto, and in the event of
termination of this Agreement pursuant to any other clause of Section 1(c), such termination shall become effective with respect to such terminating Counterparty and TMA only and not with respect to any other Counterparties, in each case, as of
5:00 P.M. (New York City time) on the effective date thereof, whereupon with respect to all parties or such Counterparty and TMA only, as the case may be, none of the provisions of this Agreement (and any agreement giving effect to the provisions
hereof) shall have any further force or effect and the related Financing Agreements shall operate as if TMA and the Counterparties had not executed this Agreement, except that (i) in the event of expiration pursuant to Section 1(a) if the
Compliance Requirements as to all Counterparties are satisfied or termination pursuant to Section 1(b), Sections 3(d), 3(j), 13, 14, 15, 16, 18 and 20 (and any agreement giving effect to the provisions thereof) shall survive such expiration or
termination and (ii) in the event of any expiration pursuant to Section 1(a) if the Compliance Requirements as to all Counterparties are not satisfied or termination pursuant to Section 1(c), Sections 2(f), 3(a), 3(b), 3(d), 3(j), 13,
14, 15, 16, 18 and 20 (and the Security Agreement and any other agreement giving effect to the provisions thereof) shall survive such expiration or (with respect to such Counterparty) such termination. 
 (e) For the purposes of determining which Counterparties should be considered for determining the Required Terminating Counterparties (as
defined in the Security Agreement), and the time when such determination should be made, any Counterparty may request that any other Counterparty verify whether it has terminated the Override Agreement, and such Counterparty receiving such request
must respond to such request within one business day. 
 SECTION 2. Certain Terms Overridden During Override Period. Solely during the
Override Period, the existing terms of each of the Financing Agreements shall be overridden, suspended and superseded to the extent set forth below: 
 (a) Extension of Maturity. The “Repurchase Date”, “Cash Settlement Date”, “Physical Settlement Date”, “Maturity Date”, “Early Termination Date” or loan
termination date (or any specified date of like meaning) (each, a “Financing Transaction Termination Date”) with respect to such Financing Agreement shall be deemed to be March 16, 2009, except that a Financing Transaction
Termination Date that is subsequent to March 16, 2009 shall continue to be in effect and shall not be accelerated to March 16, 2009 solely by reason of this sentence. For the avoidance of doubt, (i) for purpose of the preceding
sentence, no transaction under the Financing Agreements shall be deemed to have a Financing Transaction Termination Date subsequent to March 16, 2009 as the result of any deemed renewal, extension or “roll” of a transaction under such
Financing Agreements during the Override Period and (ii) the Counterparties acknowledge and agree that during the Override Period no “Event of Default”, “Termination Event” or similar event under any Financing Agreement
shall entitle the applicable Counterparty to accelerate the related Payment Obligations to any date earlier than March 16, 2009. 
  

 -4- 








 (b) Standstill. Each Counterparty agrees that during the Override Period it will
not: (i) invoke any margin maintenance requirement, credit support requirement or capital call or any process of like import, including calls with respect to reference collateral or deficiency claims under Auction Swaps (each, a “Margin
Call”) against TMA under any Financing Agreement to which it is a party, or (ii) otherwise exercise remedies against TMA, including under applicable non-bankruptcy law with respect to any “Purchased Securities” or
“Collateral” (or any term of like meaning, including margin collateral with respect to Auction Swaps) that is subject to a Financing Agreement (collectively and as to each Financing Agreement individually, the
“Collateral”). For the avoidance of doubt, any securities or other property purchased by a Counterparty or an affiliate of any Counterparty pursuant to an Auction Swap shall not constitute Collateral hereunder. 
 (c) Spread. With respect to the Collateral, the interest rate spread for the Financing Agreements shall be reset monthly and shall
be equal to one-month LIBOR plus the applicable interest rate spread set forth on Schedule IV. 
 (d) Collection and
Application of Collateral Payments. The Counterparties shall collect all principal and interest payments with respect to Collateral (“Collateral Payments”). Each Counterparty shall apply, as promptly as practicable, all
Collateral Payments that it receives against Payment Obligations other than Margin Calls, but including deficiency amounts relating to Auction Swaps which have previously had their call dates (such amounts, with respect to a Counterparty’s
Financing Agreements, as of any date of determination, the “Repayment Obligations”), such amounts to be applied in accordance with Section 5(a). In addition, on the 15th day of each calendar month following the Effective Date,
TMA, on the one hand, and the Counterparties, on the other, shall reconcile their respective calculations of the outstanding balances under the Financing Agreements (and in this connection TMA and the Counterparties agree to exchange information,
and otherwise to cooperate with one another in good faith, in such manner as may be required to make such reconciliation possible). 
 (e) No Return of Collateral Required. The Counterparties shall not be obligated during the Override Period to return to TMA any Collateral (or any portion of Collateral), even if the Counterparties would have been required to return
to TMA such Collateral (or any portion of such Collateral) pursuant to the Financing Agreements. Any Counterparty may, in its sole discretion (but under no circumstances shall be required to), exchange Collateral for other securities to be held as
Collateral in connection with proposed resecuritizations of existing Collateral by TMA. 
 (f) Incentive Management
Fee. Any incentive management fee (but not base fee) payable by TMA to the Manager during the Override Period, shall be accrued, but not paid to the Manager. An amount equal to such accrued, but not paid, incentive management fee (the
“Accrued Incentive Fee”) shall instead be paid to the Counterparties pro rata (as defined below) for application to the Payment Obligations on the date that such incentive management fee otherwise would have been paid to the Manager
and shall be applied to reduce the Payment Obligations. The Manager agrees (i) to subordinate its right to payment of any Accrued Incentive Fee to any deficiency suffered by the 

  

 -5- 








 
Counterparties under the Financing Agreements, and (ii) to enter into any agreement reasonably requested by the Counterparties to confirm such
subordination. Additionally, no cash payments by TMA shall be made on account of any long-term incentive awards during the Override Period. 
 (g) Application of Agreement. The parties acknowledge that it is their intention to apply this Agreement to all transactions outstanding on the date hereof which are under Master Repurchase Agreements or Global
Master Securities Lending Agreements, are auction swaps under ISDA Master Agreements or interest rate caps under ISDA Master Agreements, or are transactions under any other Margin Document, and are between TMA and any such Counterparty or
wholly-owned subsidiary of such Counterparty (other than, in the case of The Royal Bank of Scotland Plc, Citizens Financial Group, Inc., ABN AMRO Bank N.V. or any subsidiary of either of them) (each, a “Current Transaction”), and
accordingly, the parties agree that any Current Transaction for which a balance is not referenced in Schedule I shall nonetheless be subject to Sections 2(a) and 2(b) of this Agreement (but not to any other provision of this Agreement or to any
provisions of any other Transaction Document other than any netting agreement) as if such Current Transaction were under a Financing Agreement. As used herein, “Margin Document” means any financing agreement or similar agreement
under which the counterparty may be entitled to make margin calls on TMA (but, for the avoidance of doubt, does not include any netting agreement). 
 SECTION 3. Agreements of TMA. TMA agrees: 
 (a) so long as the Compliance Requirements as to all
Counterparties have not been satisfied and there are amounts held therein, to maintain the Liquidity Fund Account and Liquidity Fund Cash Account (each as defined in the Security Agreement, and collectively, the “Liquidity Fund”),
in an initial aggregate balance, as of November 30, 2008, of $41,244,143.18 (which amount includes accrued interest through November 30, 2008, and is calculated after giving effect to any withdrawals made from the Liquidity Fund to fund
payments to the Counterparties required by Section 3(i) but before giving effect to any withdrawals from the Liquidity Fund made by TMA on the Effective Date in accordance with this Section 3(a)), and thereafter subject to adjustment as
set forth below. The Liquidity Fund shall be used only for the purposes and on the terms and conditions specified in this Agreement, the Security Agreement and the Control Agreement. TMA agrees that (1) it will not in any month withdraw from
the Liquidity Fund more than the amount necessary to fund its operating expenses and debt service for the related month (or, in the case of December 2008, to fund (or reimburse TMA for) operating expenses and debt service payable by TMA in such
month or in November 2008) and (2) in no event shall it withdraw in any month an amount that together with all other amounts withdrawn since the date of this Agreement exceeds the amount set forth below for such month: 
  

				
	 Month
	  	Amount
	 December 2008
	  	$	26,819,000.00
	 January 2009
	  	$	37,547,000.00
	 February 2009
	  	$	41,244,143.18
	 March 2009
	  	$	41,244,143.18

  

 -6- 








 (b) in the event that TMA sells its mortgage servicing rights at any time when the
Compliance Requirements as to all Counterparties have not been satisfied, it will pay the net proceeds to the Counterparties pro rata (as defined below) to reduce the outstanding Payment Obligations. Any sale of mortgage servicing rights by TMA
shall be effected in cash at a price, confirmed by an independent third-party valuation reasonably acceptable to TMA and the Counterparties, that would have been obtained in an at-arm’s-length transaction. TMA shall not change the sub-servicer
servicing the mortgage loans subject to the mortgage servicing rights at any time when the Compliance Requirements as to all Counterparties have not been satisfied without the prior written consent of the Counterparties, which consent shall not be
unreasonably withheld or delayed. The Counterparties acknowledge and agree that this Section 3(b) shall not apply to any sales of whole loans made by TMA on a servicing-released basis; 
 (c) to suspend TMI’s common dividend for the Override Period, provided that TMI may declare in December 2008, for payment in
January of the following calendar year, a dividend of up to 87% of TMI’s taxable income for the calendar year 2008; 
 (d) to issue to the Counterparties not later than the fifth business day after the Effective Date (as defined below) additional “penny” warrants to purchase 14,176,464 shares of TMI common stock. Each such warrant will be
exercisable for a period of 5 years at an exercise price of $0.01 per share of common stock of TMI and have terms substantially similar to the terms of warrants previously granted to the Counterparties; provided that such warrants shall not
be entitled to further anti-dilution adjustments. Warrants will be allocated to each Counterparty in the amounts set forth on Schedule II; 
 (e) during the Override Period, not to enter into any new transactions under existing, or into any new, repurchase agreements, securities lending agreements, ISDA Master Agreements or similar agreements to deliver any
additional collateral thereunder without the written consent of the Counterparties. Neither the foregoing provision, nor anything else in this Agreement, shall prevent (i) (A) the maintenance or renewal of the Financing Agreements,
(B) any transaction permitted by Section 3(f), or (C) the early termination, unwind or amendment of any Auction Swap (provided that such early termination, unwind or amendment is consensual between TMA and the related
Counterparty and does not require any cash payment or delivery of any additional collateral by TMA, or in any way impair, reduce or require any application of any Collateral (for the purpose of this subparagraph, as defined in the Security
Agreement) other than Collateral of the related Counterparty consisting of its Financing Agreements, Financing Agreements of an Affiliate of such Counterparty, any Financing Agreement Securities related to any of the foregoing, all Proceeds relating
to any of the foregoing or the Financing Agreement Collateral Account of such Counterparty or that of any of its Affiliates, consistent with the last sentence of Section 6.01(a) of (and in the case of any defined terms, as defined in) the
Security Agreement), or (ii) the execution and performance by TMA of warehouse lending agreements (with existing lenders (including Counterparties) or with new lenders) in an aggregate amount not to exceed $700 million outstanding at any one
time. This provision also does not apply to interest rate cap, corridor and swap agreements; 
  

 -7- 








 (f) that it may (and the Counterparties acknowledge and agree that TMA may) at any time
repay or refinance any part of the Financing Amount of any Counterparty (the “Original Counterparty”) on such terms as TMA and the Original Counterparty may agree (each, a “Refinancing Transaction”); provided,
however, that during the Override Period TMA shall repay or refinance, as applicable, the Financing Amount of each other Counterparty in the same proportion as the Financing Amount repaid or refinanced with respect to the Original Counterparty
on substantially equivalent terms to the repayment or refinancing of the Original Counterparty. In addition, TMA may (and the Counterparties acknowledge and agree that TMA may) at any time authorize any Counterparty to sell or otherwise transfer all
or any part of its Collateral on such terms as TMA and the Counterparty may agree (including, if applicable, agreement on the application to be made of the sale proceeds) (each, a “Resale Transaction”); provided, however,
that during the Override Period TMA shall not authorize any Counterparty to effect a Significant Resale Transaction. As used in this Section 3(f) in relation to any Counterparty: 
 “Base Amount” means an amount equal to 15% of the Most Recent Balance. 
 “Financing Amount” means, as of any date of determination, the aggregate principal amount of all outstanding advances, loans,
“Purchase Prices” or other extensions of credit made to TMA by such Counterparty under any Financing Agreement (including, without limitation, any obligation of TMA to return cash collateral in connection with securities loans, but
excluding any obligations with respect to Auction Swaps or Interest Rate Caps). 
 “Most Recent Balance” means the dollar
amount set forth for such Counterparty in Schedule I hereto under the heading “FINANCIAL EXPOSURE - Repo and Securities Lending Balances as of October 31, 2008”. 
 “Significant Resale Transaction” means any Resale Transaction that, when taken together with all other Resale Transactions effected by
the applicable Counterparty during the Override Period, will reduce such Counterparty’s Financing Amount by an amount exceeding the Base Amount; 
 (g) that Sections 3(e) and 3(f) shall not be interpreted to restrict the right of any Counterparty to effect any assignment, transfer, participation or pledge of its rights or obligations under this Agreement or any
Financing Agreement that otherwise would be permitted under Section 7; 
 (h) to provide to the Counterparties
(i) no later than the 15th day of each month, a monthly report (x) setting forth in reasonable detail its calculation of the outstanding balances under the Financing Agreements and in the Liquidity Fund, and (y) confirming that during
the preceding calendar month TMA has complied with its obligations under Sections 2(f), 3(a), 3(b) and 3(j), and (ii) prompt notice of the occurrence of an Override Termination Event; 
  

 -8- 








 (i) on the Effective Date (as defined below), to cause each Counterparty to receive for
application to the Repayment Obligations owing to it the amount in cash set forth opposite its name in Schedule III; and 
 (j) during the period extending through March 17, 2009 (and whether or not this Agreement has been terminated), to offer each Counterparty the opportunity, on substantially similar terms as any other proposed manager, to act with
respect to TMA’s securitizations and resecuritizations, (i) on a rotating basis among all Counterparties, as sole lead manager, and (ii) as co-lead manager on each securitization in which such Counterparty is not acting as sole lead
manager. The term “resecuritization” means a transaction in which existing securities are repackaged and new, rated securities are issued. 
 SECTION 4. Representation of TMA. TMA represents that it has no exposure under any repurchase agreements, securities lending agreements, auction swaps or interest rate caps or any similar transaction, except
for its exposures to the Counterparties and their affiliates. 
 SECTION 5. Agreements of each Counterparty. Each Counterparty agrees:

 (a) to apply as promptly as practicable all Collateral Payments received by it to the payment of, first, any outstanding
price differentials, interest factors, interest or income payments under Financing Agreements that are Applicable Standard Repurchase Agreements or Applicable Global Master Securities Lending Agreements; second, any outstanding reasonable legal fees
of such Counterparty incurred in connection with, without limitation, the negotiation, drafting, execution, administration and enforcement of the Transaction Documents; third, amounts owed as the return of cash collateral in connection with any
Applicable Global Master Securities Lending Agreement and the principal portion of any outstanding Repurchase Prices under Applicable Standard Repurchase Agreements; fourth, any amounts payable by TMA under Financing Agreements that are Applicable
Structured Repurchase Agreements; and, thereafter, to the payment of any other outstanding obligations of TMA and its affiliates to such Counterparty and its affiliates (other than Margin Calls, but including deficiency amounts relating to Auction
Swaps which have previously had their call dates), including (for purposes of this final clause) as may be specified in any applicable netting agreement. As used in this Agreement in relation to any Counterparty, the term “Applicable
Standard Repurchase Agreement” means any Repurchase Agreement identified as a “Standard Repurchase Agreement” in Schedule I hereto to which such Counterparty is a party; the term “Applicable Global Master Securities
Lending Agreement” means any Global Master Securities Lending Agreement identified as a “Global Master Securities Lending Agreement” in Schedule I hereto to which such Counterparty is a party, and the term “Applicable
Structured Repurchase Agreement” means any Repurchase Agreement identified as a “Structured Repurchase Agreement” in Schedule I hereto to which such Counterparty is a party; and 
  

 -9- 








 (b) to apply toward the payment of any Payment Obligations that then remain outstanding
any Collateral Payments that the Counterparty receives after March 15, 2009 (including, without limitation, any payments that the Counterparty receives on Collateral having record dates that precede, but payment dates that follow,
March 15, 2009); provided that such Counterparty has not terminated its transactions under its related Financing Agreement; and provided, further, if at the time the Counterparty receives any such Collateral Payment, the
Compliance Requirements as to all Counterparties have been satisfied and subject to any applicable netting agreements, the Counterparty shall promptly transfer the full amount of such Collateral Payment to TMI. 
 SECTION 6. Disclosure. Upon execution of this Agreement by the Counterparties, TMA may disclose the substance of this Agreement by press release
and via the filing of a current report on Form 8-K with the SEC. 
 SECTION 7. Successors. The terms of this Agreement shall be
binding upon, and shall inure to the benefit of, the parties hereto and their respective corporate successors, assigns, and representatives, provided that (x) TMA may not assign or otherwise transfer any of its rights or obligations
hereunder or under any Financing Agreement without the prior written consent of each affected Counterparty and (y) a Counterparty may not assign or otherwise transfer any of its rights or obligations hereunder or under any Financing
Agreement except (i) to an Eligible Assignee (as defined below), (ii) by way of participation, or (iii) by way of pledge or assignment of a security interest (provided that no such pledge or assignment shall release the
Counterparty from any of its obligations hereunder or thereunder or substitute any such pledgee or assignee for the Counterparty as a party hereto or thereto (and any other attempted assignment or transfer by any party hereto shall be null and
void). For purposes of this Section, “Eligible Assignee” means (a) an affiliate of the Counterparty; and (b) any other person (other than a natural person) approved by TMA (such approval not to be unreasonably withheld or
delayed); provided that no such approval shall be required if an Override Termination Event has occurred and is continuing; and provided further, that each Eligible Assignee shall acknowledge to TMA in writing that such Eligible
Assignee is bound by all obligations of such Counterparty under this Agreement as if it had executed the same as a Counterparty. 
 SECTION
8. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be construed in accordance with the laws of the State of New York without regard to any principles of conflict of laws (other than New York General
Obligations Law §5-1401 or 5-1402). TMA and each Counterparty each hereby agrees that any LEGAL ACTION OR PROCEEDING AGAINST IT WITH RESPECT TO THIS AGREEMENT, OR ANY OF THE AGREEMENTS, DOCUMENTS OR INSTRUMENTS DELIVERED IN CONNECTION WITH THIS
AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA SITTING IN THE BOROUGH OF MANHATTAN IN THE CITY OF NEW YORK, and, by execution and delivery hereof, each of TMA and each Counterparty accepts and
consents to, for itself and in respect to its property, generally and unconditionally, the jurisdiction of the aforesaid courts with respect to any action or proceeding brought by TMA and/or each Counterparty. 
 TMA AND EACH COUNTERPARTY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY AND ALL RIGHTS EACH MAY 

  

 -10- 








 
HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED ON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT, OR ANY OTHER DOCUMENTS AND
INSTRUMENTS EXECUTED IN CONNECTION HEREWITH, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF TMA OR ANY COUNTERPARTY. THIS PROVISION IS A MATERIAL INDUCEMENT FOR EACH COUNTERPARTY TO ENTER INTO THIS
AGREEMENT. 
 SECTION 9. Severability of Provisions. If any one or more of the covenants, agreements, provisions or terms of this
Agreement shall be held invalid for any reason whatsoever, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Agreement and shall in no way affect the
facility or enforceability of the other covenants, agreements, provisions or terms of this Agreement. 
 SECTION 10. Counterparts;
Effectiveness. This Agreement may be executed in several counterparts and by each party on a separate counterpart, each of which when so executed and delivered shall be an original, and all of which together shall constitute one instrument.
Signatures transmitted electronically (including by fax or e-mail) shall have the same legal effect as the originals, but each party nevertheless shall upon request of any other party deliver original signed counterparts of this Agreement to each
other party (with the failure to so deliver not effecting the enforceability of this Agreement as to such non-delivering party). This Agreement shall be effective as of the date hereof when (i) TMI has received an executed counterpart from each
party hereto, (ii) Amendment No. 1 to the Security Agreement and Amendment No. 2 to the Control Agreement have become effective in the forms previously agreed by TMI and the Counterparties, and (iii) each of MatlinPatterson

to the Counterparties a release substantially in the form set forth in Section 20(a) (the “Effective Date”). 
 SECTION
11. Complete Agreement. This Agreement and the other Transaction Documents express the entire understanding of the parties with respect to the transactions contemplated hereby. No prior negotiations or discussions shall limit, modify, or
otherwise affect the provisions hereof as in effect on and after the date hereof. 
 SECTION 12. No Other Waivers. Except as expressly
set forth in this Agreement, by entering into this Agreement, none of the Counterparties shall be deemed to have waived any right under any Financing Agreement or at law or at equity. Each Counterparty’s agreement to extend the Repurchase Date
or make any other accommodation hereunder on one occasion shall in no event constitute its agreement to extend the Repurchase Date or make any other accommodation hereunder on any other occasion.

 SECTION 13. Further Assurances. At any time and from time to time upon prior written request of a
Counterparty, at the sole expense of TMA, TMA will promptly and duly execute and deliver, or cause to be duly executed and delivered, such further instruments and documents and take, or cause to be taken, such further actions, as such Counterparty
may reasonably request for the purposes of obtaining or preserving the full benefits of this Agreement, the Security Agreement and the Financing Agreements. 
 SECTION 14. Other Provisions Remain in Effect. Except as overridden, suspended or superseded hereby, the terms of each Financing Agreement are and shall continue to be in full force and effect and are in
all respects ratified and confirmed, and this Agreement is expressly made supplemental to and a part thereof. TMA hereby affirms and ratifies each obligation and other similar liability to the Counterparties to which it is a party as of the date
hereof (including, without limitation, obligations and liabilities which do not arise under Financing Agreements) and, except as provided for in this Agreement during the Override Period, all such obligations and other liabilities shall continue in
full force and effect unless and until released or discharged pursuant to this Agreement or otherwise. After the termination of the Override Period, with respect to any Counterparty, such Counterparty shall be entitled to exercise all of its rights
and remedies under the relevant Financing Agreements as in effect without regard to this Agreement, and neither this Agreement nor any delay in the exercise of any right or remedy pursuant hereto shall constitute a waiver of any such right or remedy
or provide any defense or estoppel in respect thereof, all such rights and remedies being expressly preserved hereby. 
 SECTION 15.
Expenses. TMA agrees to pay or reimburse the Counterparties for all of their reasonable out-of-pocket costs and expenses in connection with the negotiation, preparation, execution, delivery and enforcement of this Agreement and the agreements
referred to herein, including, without limitation, the fees and expenses of Davis Polk & Wardwell, special counsel to the Counterparties. 
 SECTION 16. Intent. The parties recognize that each of the Financing Agreements that is a Master Repurchase Agreement is a “repurchase agreement” as that term is defined in Section 101 of Title 11 of the United States
Code (as amended, the “Bankruptcy Code”), that each of the Financing Agreements that is an ISDA Master Agreement is a “swap agreement” as that term is defined in Section 101 of the Bankruptcy Code, that each of the
Financing Agreements that is a Global Master Securities Lending Agreement, together with any transaction thereunder, is a “securities contract” as that term is defined in Section 741(7) of the Bankruptcy Code and that each of the
Transaction Documents is a “repurchase agreement”, “swap agreement” or “securities contract”, as the case may be, as such terms are defined under Section 101 or 741(7) of the Bankruptcy Code, as applicable.

things, the agreements contained herein, to the fullest extent permitted by law, each of TMA and the Manager fully and finally irrevocably and unconditionally releases and discharges each Counterparty and its respective affiliates, officers,

claims, causes of action, damages and liabilities (collectively, “Claims”) (i) arising on or prior to the date hereof out of, or related to, the Original Override Agreement, the Transaction Documents, any other Current
Transactions and any netting agreements, (ii) arising on or prior to the date hereof with respect to, or in connection with, the application of the Collateral or the proceeds thereof to the Payment Obligations in accordance with the Transaction
Documents and any netting agreements, or any similar action in connection with any other Current Transaction, or (iii) arising at any time with respect to, or in connection with, the termination and unwinding by a Counterparty of a Financing
Agreement in a manner consistent with a Counterparty’s past practices and in accordance with its corresponding Financing Agreements, or any similar action in connection with any other Current Transaction. TMA and the Manager each covenants not
to commence or maintain any claim or suit against any Released Party or join any Released Party (as applicable) to a suit with respect to the foregoing, whether at law or in equity. Each Counterparty fully and finally irrevocably and unconditionally
releases each other Counterparty from any Claims described in clause (ii) or (iii) of the second preceding sentence.

 -14- 








 
unconditionally releases and discharges each of TMI, TMHL, TMHS and the Manager and each person that executes a release in favor of the Counterparties
pursuant to Section 10(iii) hereof and their respective affiliates, officers, directors, employees, advisors and other agents from any Claims that arose on or prior to the date hereof and that resulted from or relate to (i) the failure by
any of TMI, TMHL or TMHS to satisfy any Margin Calls made by any Counterparty on or after March 17, 2008 and prior to the date hereof under any Financing Agreement or (ii) any Claims (other than Repayment Obligations or like obligations
under Current Transactions) that arose on or after March 17, 2008 and on or prior to the date hereof and that arose out of, or are related to, the Original Override Agreement, the Transaction Documents, any other Current Transaction or any
netting agreements. Each Counterparty covenants not to commence or maintain any claim or suit against TMI, TMHL, TMHS, the Manager or any other person entitled to the benefit of this Section 20(b) or join any such entity or person to a suit
with respect to the foregoing, whether at law or in equity. 
 (c) In entering into this Agreement, each party has consulted with and been
represented by counsel and expressly disclaims any reliance on any representations (other than those expressly made herein and in the other Transaction Documents), acts or omissions by any of the other parties and hereby agrees and acknowledges that
the validity and effectiveness of the release set forth above do not depend in any way on any such representations, acts and/or omissions or the accuracy, completeness or validity thereof. The provisions of this Section shall survive the termination
of the Transaction Documents and payment in full of all amounts owing thereunder. 
 (d) For the avoidance of doubt, for the purposes of
calculating any amounts owed under the Financing Agreements on or after the date hereof (“Future Calculations”), nothing in this Section 20 shall preclude any unpaid amount arising or existing under the Financing Agreements on
