No election by the Company under this Section 1.4(a) shall be effective unless received by each Purchaser on or prior to the date of notice of the time fixed for the hearing to approve the Confirmation Order under Bankruptcy Rule 2002. Any election by the Company under this Section 1.4(a) shall be binding and irrevocable.

(b) If the Plan as confirmed provides for the commencement on or about the Effective Date of a broadly distributed public offering of Permitted Replacement Shares on terms and conditions and with one or more underwriters and a plan of distribution, the Company may elect by written notice to each Purchaser on or prior to the date of notice of the time fixed for the hearing to approve the Confirmation Order under Bankruptcy Rule 2002 to specify a number of Shares to be purchased by the Purchasers at Closing as Shares to be subject to repurchase after Closing pursuant to this Section 1.4(b) (the “Reserved Shares”); provided, that the excess of (i) its GGP Pro Rata Share of the Total Purchase Amount minus (ii) the Reserved Shares shall not be less than its GGP Pro Rata Share of 190,000,000. If the Company elects to designate any Reserved Shares, the Company shall pay to each Purchaser in cash on the Effective Date an amount equal to $0.25 per Reserved Share. Upon payment of such amount, the Company shall thereafter have the right to elect by written notice to each Purchaser (a “Repurchase Notice”) on or prior to the 25th day after the Effective Date (or, if not a Business Day, the next Business Day) to repurchase from each Purchaser a number of Shares equal to such Purchaser’s GGP Pro Rata Share of the greater of (x) the aggregate amount of Permitted Replacement Capital Shares sold by the Company in such public offering and (y) the Reserved Shares. The purchase price for any repurchased Shares shall be $10.00 per Share, payable in cash in immediately available funds against delivery of the repurchased Reserved Shares

on a settlement date determined by the Company and each Purchaser and not later than the date that is 30 days after the Effective Date. Any Repurchase Notice under this Section 1.4(b) shall, when taken together with this Agreement, constitute a binding offer and acceptance and be irrevocable.”

Within one Business Day of the date of the entry of the Approval Order, the Company and the warrant agent shall execute and deliver the warrant and registration rights agreement in the form attached hereto as Exhibit G (with only such changes thereto as may be reasonably requested by the warrant agent and reasonably approved by each Purchaser) (the “Warrant Agreement”) pursuant to which there will be issued to PSCM 17,142,857 warrants (the “Warrants”) each of which, when issued, delivered and vested in accordance with the terms of the Warrant Agreement, will entitle the holder to purchase one (1) share of Common Stock at an initial price of $15.00 per share subject to adjustment as provided in the Warrant Agreement. The Warrant Agreement shall provide that the Warrants shall vest in accordance with Section 2.2(b) and Schedule A of the Warrant Agreement. For the avoidance of doubt, Warrants that have not vested may not be exercised. The Plan shall provide that upon the Effective Date, the Warrants, regardless of whether or not vested, shall be cancelled for no consideration. The Plan shall also provide that there shall be issued to each Purchaser pro rata in accordance with the number of shares of New Common Stock or GGO Common Stock, as the case may be, purchased, an aggregate of (i) 17,142,857 fully vested warrants (the “New Warrants”) each of which entitles the holder to purchase one (1) share of New Common Stock at an initial purchase price of $10.50 per share subject to adjustment as provided in the underlying warrant agreement and (ii) 20,000,000 fully vested warrants (the “GGO Warrants”) each of which entitles the holder to purchase one (1) share of GGO Common Stock at a price of $5.00 per share subject to adjustment as provided in the underlying warrant agreement, each in accordance with the terms set forth in a warrant and registration rights agreement with terms substantially similar to the terms set forth in the Warrant Agreement, except that the expiration date for each New Warrant and GGO Warrant shall be the seventh year anniversary of the date on which such warrants are issued. PSCM, in its sole discretion, may designate that some or all of the New Warrants or GGO Warrants be issued in the name of, and delivered to, any member of the Purchaser Group in accordance with and subject to the Designation Conditions.”

11. Amendments to Section 5.16(d). Section 5.16(d) of the Agreement is hereby amended and restated in its entirety to read as follows:

“(d) It is the intention of the parties that any Reserve should not alter the intended allocation of value between GGO and the Company as Claims are resolved over time. Accordingly, the Plan shall provide that, if a GGO Promissory Note is required to be issued at Closing and there is a Reserve Surplus Amount as of the end of any fiscal quarter prior to the maturity of the GGO Promissory Note, then the principal amount of the GGO Promissory Note shall be reduced, but not below zero, by (i) if and to the extent that such Reserve Surplus Amount as of such date is less than or equal to the Net Debt Surplus Amount, 80% of the Reserve Surplus Amount, and otherwise (ii) 100% of an amount equal to the Reserve Surplus Amount; provided, however, that because this calculation may be undertaken on a periodic basis, for purposes of clauses (i) and (ii), no portion of the Reserve Surplus Amount shall be utilized to reduce the amount of the GGO Promissory Note if it has been previously utilized for such purpose. In the event that any party requests an equitable adjustment to this formula, the other parties shall consider the request in good faith.”

12. Amendment to Section 6.4. Section 6.4 of the Agreement is hereby amended by inserting at the end thereof the following:

reasonably requested by the managing underwriter in connection with such offering.”

13. Amendments to Article VI. Article VI of the Agreement is hereby amended by adding at the end thereof the following new sections:

“SECTION 6.8. [Intentionally Omitted.]”

“SECTION 6.9. Additional Backstops.

(a) The Company may, at its option, include in the Plan an offering (the “GGP Backstop Rights Offering”) to its then-existing holders of Common Stock of rights to purchase New Common Stock on the Effective Date in an amount sufficient to yield to the Company aggregate net proceeds on the Effective Date of up to $500,000,000 or such lesser amount as the Company may determine (the “GGP Backstop Rights Offering Amount”). In connection with the GGP Backstop Rights Offering:

(i) Each Purchaser and the Brookfield Investor (together with the Purchaser, the “Backstop Investors”) and the Company shall appoint a mutually-acceptable and internationally-recognized investment bank to act as bookrunning dealer-manager for the GGP Backstop Rights Offering (the “Dealer Manager”) pursuant to such arrangements as they may mutually agree;

(ii) the Dealer Manager will, no later than the fifth business day in advance of the commencement of the solicitation of votes on the Plan and offering of rights in the GGP Backstop Rights Offering (which shall not be longer than 60 days), recommend in writing to the Backstop Investors and the Company the number of shares of New Common Stock that may be purchased for each share of Common Stock , the subscription price of such purchase and the other terms for the rights offering that the Dealer Manager determines are reasonably likely to yield committed proceeds to the Company at the Effective Date equal to the GGP Backstop Rights Offering Amount (it being understood that the Dealer Manager will have no liability if it is later determined that its good faith determination was erroneous);

(iii) the Backstop Investors agree, severally but not jointly and severally, to subscribe, or cause one or more designees to subscribe, for New Common Stock on a pro rata basis to the extent rights are declined by holders of Common Stock, subject to the subscription rights among the Backstop Investors set forth in clause (iv);

(iv) the Backstop Investors will have subscription rights in any such offering allowing them to maintain their respective proportionate pro forma New Common Stock-equivalent interests on a Fully Diluted Basis with the effect that the Backstop Investors will be assured of the ability to acquire such number of

shares of New Common Stock as would have been available to them pursuant to Section 5.9 had the GGP Backstop Rights Offering been made after the Closing;

(v) the Backstop Investors will receive aggregate compensation in the form of New Common Stock (whether or not the backstop commitments are utilized) with a value equal to three percent (3%) of the GGP Backstop Rights Offering Amount; and

(vi) the amount of New Common Stock to be purchased pursuant to the GGP Backstop Rights Offering will be subject to reduction to the extent that either (A) the Company Board determines in its business judgment after consultation with the Backstop Investors that it has sufficient liquidity and working capital available to it in light of circumstances at the time and the costs and benefits to the Company of consummation of the GGP Backstop Rights Offering or (B) the Backstop Investors have agreed that they will provide to the Company, in lieu of the GGP Backstop Rights Offering the Bridge Securities contemplated in clause (b) below.

(b) The Company shall give each Backstop Investor written notice of its estimate of the amount the Backstop Investors will be required to fund pursuant to Section 6.9(a) no later than six (6) Business Days prior to the Closing Date. If each Backstop Investor agrees, the Backstop Investors shall have two (2) Business Days from the date of receipt of such notice to notify the Company in writing that they intend to elect to purchase from the Company in lieu of all or part of the proceeds to be provided by the GGP Backstop Rights Offering its pro rata portion of senior subordinated unsecured notes and/or preferred stock instruments (at the election of the Backstop Investors) on market terms except as provided below (the “Bridge Securities”). The Bridge Securities would have a final maturity date, in the case of a note, and a mandatory redemption date, in the case of preferred stock, on the 270th day after the Effective Date, would not require any mandatory interim cash distributions except as contemplated in (i) below, and would yield to the Company on the Closing Date cash proceeds (net of OID) of at least the proceeds from the GGP Backstop Rights Offering that such Bridge Securities are intended to replace. The Bridge Securities would be subordinated in right of payment to any New Debt, would have market coupon and fees, would allow for any interest due prior to maturity to be “paid in kind” (rather than paid in cash) at the election of the Company, would be prepayable, without any prepayment penalty or prepayment premium, on a pro rata basis at any time, and would otherwise be on market terms (determined such that fair value of the Bridge Securities as of the Effective Date is equal to par minus OID).

If the GGP Backstop Rights Offering is completed or the Bridge Securities are issued:

(i) unless the Backstop Investors otherwise agree, the Bridge Securities shall be subject to mandatory prepayment on a pro rata basis out of the

proceeds of any equity or debt securities offered or sold by the Company at any time the Bridge Securities are outstanding (other than the New Common Stock sold to the Backstop Investors, any New Common Stock sold in the GGP Backstop Rights Offering and the New Debt); and

(ii) if the Bridge Securities are issued and not repaid on or before the date that is thirty (30) days following the Effective Date, the Company shall conduct a rights offering in an amount equal to the outstanding amount due with respect to the Bridge Securities and with a pro rata backstop by each applicable Backstop Investor on substantially the same procedure and terms provided in clause (a) above, with such rights offering to have a subscription period of not more than 30 days that ends no later than the 10th day prior to the final maturity date or mandatory redemption of the Bridge Securities.

(c) If the Company requests the Initial Investors, in writing, at any time prior to fifteen (15) days before the commencement of solicitation of acceptances of the Plan, each Initial Investor agrees that it shall, severally but not jointly and severally, provide or cause a designee to provide its pro rata share of a backstop for new bonds, loans or preferred stock (as determined by the Initial Investor) in an aggregate amount equal to $1,500,000,000 less the Reinstated Amounts, at a market rate and market commitment fees, and otherwise on terms and conditions to be mutually agreed among the Initial Investors and the Company. The new bonds, loans or preferred stock would require no mandatory interim cash principal payments prior to the third anniversary of issuance (unless funded from committed junior indebtedness or junior preferred stock), and would yield proceeds to the Company on the Closing Date net of OID of at least $1,500,000,000 less the Reinstated Amounts. Any Initial Investor may at any time designate in writing one or more financial institutions with a corporate investment grade credit rating (from S&P or Xxxxx’x) to make a substantially similar undertaking as that provided herein and, upon the receipt of such an undertaking by the Company in form and substance reasonably satisfactory to the Company, such Initial Investor shall be released from its obligations under its applicable Investment Agreement.

(d) For the purposes of Section 6.9(a) and Section 6.9(b), the “pro rata share” or “pro rata basis” of each Backstop Investor shall be determined in accordance with the maximum number of shares of New Common Stock each Backstop Investor has committed to purchase at Closing pursuant to the Brookfield Agreement or this Agreement, as applicable, as of the date hereof, in relation to the aggregate maximum number of shares of New Common Stock all Backstop Investors have committed to purchase at Closing pursuant to the Brookfield Agreement or this Agreement, as applicable, as of the date hereof. For the purposes of Section 6.9(c), the “pro rata share” or “pro rata basis” of each Initial Investor shall be determined in accordance with the maximum number of shares of New Common Stock each Initial Investor has committed to purchase at Closing pursuant to its Investment Agreement as of the date hereof, but excluding any shares of New Common Stock the Backstop Investors have committed to purchase pursuant to this Section 6.9.”

14. Amendment to Section 7.1(l). The first sentence of Section 7.1(l) of the Agreement is hereby amended and restated in its entirety to read as follows:

15. Amendment to Section 7.1(n). Section 7.1(n) of the Agreement is hereby amended and restated in its entirety to read as follows:

“Liquidity. The Company shall have, on the Effective Date and after giving effect to the use of proceeds from Capital Raising Activities permitted under this Agreement and the issuance of the Shares, and the payment and/or reserve for all allowed and disputed claims under the Plan, transaction fees and other amounts required to be paid in cash or Shares under the Plan as contemplated by the Plan Summary Term Sheet, an aggregate amount of not less than $350,000,000 of Proportionally Consolidated Unrestricted Cash (the “Liquidity Target”) plus, the net proceeds of the Additional Financings and the aggregate principal amount of the Anticipated Debt Paydowns (or such higher number as may be agreed to by each Purchaser and the Company).”

Common Stock and the Backstop Investors, in each case, pursuant to Section 6.9(b) minus (ii) 50,000,000 shares of New Common Stock; provided, that if Indebtedness under the Xxxxx Bonds or the Exchangeable Notes is reinstated under the Plan, or the Company shall have incurred New Debt, or between the date of this Agreement and the Closing Date the Company shall have sold for cash real property assets outside of the ordinary course of business (“Asset Sales”), the Share Cap Number shall be reduced by the quotient (rounded up to the nearest whole number) obtained by dividing (x) the sum of Reinstated Amounts and the net cash proceeds to the Company from Asset Sales in excess of $150,000,000 and the issuance of New Debt by (y) the Per Share Purchase Price.”
