Each Lender shall, before 12:00 noon (New York City time) on the date of such Borrowing (in the case of a Borrowing consisting of Eurodollar Rate Advances), and before 2:00 P.M. (New York City time) on the date of such Borrowing (in the case of a Borrowing consisting of Base Rate Advances), make available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s Account, in same day funds, such Lender’s ratable portion of such Borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower at the Administrative Agent’s address referred to in Section 8.02 or at an account designated by the Borrower to the Administrative Agent in such Notice of Borrowing; provided, however, that (x) the Administrative Agent shall first make a portion of such funds equal to the aggregate principal amount of any Letter of Credit Advances outstanding on the date of such Borrowing, plus interest accrued and unpaid thereon and fees and other amounts due and payable in respect of such Letter of Credit Advances to and as of such date, available to the appropriate Issuing Bank and/or other Lenders for repayment of such Letter of Credit Advances and (y) the Administrative Agent shall next make a portion of such funds equal to the aggregate principal amount of any Swing Line Advances outstanding on the date of such Borrowing, plus interest

Alenco - Amended and Restated Credit Agreement

accrued and unpaid thereon, available to the Swing Line Bank and/or other Lenders for repayment of such Swing Line Advances.

(c) Each Notice of Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss (excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Revolving Credit Advance to be made by such Lender as part of such Borrowing when such Revolving Credit Advance, as a result of such failure, is not made on such date.

(d) Unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing comprised of Eurodollar Rate Advances or prior to 1:00 P.M. (New York City time) on the date of the proposed disbursement of any Borrowing comprised of Base Rate Advances that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Borrowing, the Administrative Agent may assume that such Lender has made such portion available to the Administrative Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent such Lender shall not have so made such ratable portion of any Borrowing available to the Administrative Agent, such Lender agrees to pay to the Administrative Agent on demand such Lender’s ratable portion of such Borrowing and all reasonable costs and expenses incurred by the Administrative Agent in connection therewith together with interest thereon at the Federal Funds Rate for each day from the date such amount is made available to the Borrower until the date such amount is paid to the Administrative Agent; provided, however, that notwithstanding such obligation if such Lender fails to so pay, the Borrower covenants and agrees that, without prejudice to any rights the Borrower may have against such Lender, the Borrower shall repay to the Administrative Agent upon demand therefor by the Administrative Agent such Lender’s ratable portion of such Borrowing and all reasonable costs and expenses incurred by the Administrative Agent in connection therewith together with interest thereon at the Base Rate in the case of a Base Rate Advance and the Eurodollar Rate in the case of a Eurodollar Rate Advance, plus the Applicable Margin with respect thereto, for each day from the date such amount is made available to the Borrower until such amount is repaid to the Administrative Agent. The amount payable to the Administrative Agent hereunder shall be set forth in a certificate delivered by the Administrative Agent to such Lender and the Borrower (which certificate shall contain reasonable details concerning the calculation of the amount payable) and shall be prima facie evidence thereof, in the absence of manifest error. If such Lender shall repay to the Administrative Agent such amount, such amount so repaid shall constitute such Lender’s Revolving Credit Advance as part of such Borrowing for purposes of this Agreement.

(e) The failure of any Lender to make the Revolving Credit Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make

Alenco - Amended and Restated Credit Agreement

its Revolving Credit Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Revolving Credit Advance to be made by such other Lender on the date of any Borrowing.

SECTION 2.03. Making the Swing Line Advances (a) Each Swing Line Borrowing shall be made on notice, given not later than 12:00 noon (New York City time) on the Business Day of the proposed Swing Line Borrowing, by the Borrower to the Swing Line Bank and the Administrative Agent.

If, in its sole discretion, it elects to make the requested Swing Line Advance, the Swing Line Bank will make the amount thereof available to the Administrative Agent at the Administrative Agent’s Account, in same day funds. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower at the Administrative Agent’s address referred to in Section 8.02 or at an account designated by the Borrower to the Administrative Agent in such Notice of Borrowing.

The Borrower hereby agrees to each such sale and assignment. Each Lender agrees to purchase its Pro Rata Share of an outstanding Swing Line Advance on (i) the Business Day on which demand therefor is made by the Swing Line Bank, provided that notice of such demand is given not later than 12:00 noon (New York City time) on such Business Day or (ii) the first Business Day next succeeding such demand if notice of such demand is given after such time.

If such Lender shall pay to the Administrative Agent such amount for the account of the Swing Line Bank on any Business Day, such amount so paid in respect of principal shall constitute a Swing Line Advance made by such Lender on such Business Day for purposes of this Agreement, and the outstanding principal amount of the Swing Line Advance made by the Swing Line Bank shall be reduced by such amount on such Business Day.

(b) Each Notice of Swing Line Borrowing shall be irrevocable and binding on the Borrower.

If (I) the requested form of such Letter of Credit is acceptable to such Issuing Bank in its sole and reasonable discretion, and (II) such Issuing Bank has received notice from the Administrative Agent that the Issuing Bank may issue such Letter of Credit (which notice shall be sent by the Administrative Agent to the Issuing Bank if the applicable conditions set forth in Article II and III have been fulfilled and the Administrative Agent has not received any notice of objection to such issuance from the Required Lenders), then such Issuing Bank will make such Letter of Credit available to the Borrower at its office referred to in Section 8.02 or as otherwise agreed with the Borrower in connection with such issuance. In the event and to the extent that the provisions of any Letter of Credit Agreement shall conflict with this Agreement, the provisions of this Agreement shall govern.

(b) Letter of Credit Reports. Each Issuing Bank shall furnish to the Administrative Agent on the first Business Day of each week a written report summarizing the issuance date, Available Amount and expiration date with respect to each Letter of Credit issued by such Issuing Bank during the previous week.

(c) Drawing and Reimbursement. The payment by any Issuing Bank of a draft drawn under any Letter of Credit shall constitute for all purposes of this Agreement the making by such Issuing Bank of a Letter of Credit Advance, which shall be a Base Rate Advance, in the amount of such draft. Upon written demand by any Issuing Bank with an outstanding Letter of Credit Advance, with a copy of such demand to the Administrative Agent, each Lender shall purchase from such Issuing Bank, and such Issuing Bank shall sell and assign to each such Lender, such Lender’s Pro Rata Share of such outstanding Letter of Credit Advance as of the date of such purchase, by making available for the account of its Applicable Lending Office to the Administrative Agent for the account of such Issuing Bank, by deposit to the Administrative Agent’s Account, in same day funds, an amount equal to the portion of the outstanding principal amount of such Letter of Credit Advance to be purchased by such Lender. Promptly after receipt thereof, the Administrative Agent shall transfer such funds to such Issuing Bank. The Borrower hereby agrees to each such sale and assignment. Each Lender agrees to

purchase its Pro Rata Share of an outstanding Letter of Credit Advance on (i) the Business Day on which demand therefor is made by the Issuing Bank which made such Advance, provided notice of such demand is given not later than 12:00 noon (New York City time) on such Business Day or (ii) the first Business Day next succeeding such demand if notice of such demand is given after such time. Upon any such assignment by an Issuing Bank to any other Lender of a portion of a Letter of Credit Advance, such Issuing Bank represents and warrants to such other Lender that such Issuing Bank is the legal and beneficial owner of such interest being assigned by it, free and clear of any liens, but makes no other representation or warranty and assumes no responsibility with respect to such Letter of Credit Advance, the Loan Documents or any Loan Party. If and to the extent that any Lender shall not have so made the amount of such Letter of Credit Advance available to the Administrative Agent, such Lender agrees to pay to the Administrative Agent forthwith on demand such amount together with interest thereon, for each day from the date of demand by such Issuing Bank until the date such amount is paid to the Administrative Agent, at the Federal Funds Rate for its account or the account of such Issuing Bank, as applicable.

In the event that the Letter of Credit Sub-Commitments or the Swing Line Sub-Commitments at any time exceed the Revolving Credit Commitments, the Letter of Credit Sub-Commitments or the Swing Line Sub-Commitments, as the case may be, shall at such time automatically be reduced to an amount equal to the amount of the Revolving Credit Commitments. The Administrative Agent shall give each Lender and each Issuing Bank prompt notice of any such reduction of the Revolving Credit Commitments, the Swing Line Sub-Commitments and/or the Letter of Credit Sub-Commitments.

against such Defaulting Lender, including without limitation in respect of any breach of such Defaulting Lender of its obligations under this Agreement prior to such termination.

(A) any lack of validity or enforceability of any Loan Document, any Letter of Credit Agreement, any Letter of Credit or any other agreement or instrument relating thereto (all of the foregoing being, collectively, the “L/C Related Documents”);

(B) any change in the time, manner or place of payment of, or in any other term of, all or any of the obligations of the Borrower in respect of any L/C Related Document or any other amendment or waiver of or any consent to departure from all or any of the L/C Related Documents;

Alenco - Amended and Restated Credit Agreement

SECTION 2.09. Interest Rate Determination. (a) The Administrative Agent shall give prompt notice to the Borrower and the Lenders of the applicable interest rate determined by the Administrative Agent for purposes of Section 2.08(a).

(b) If, with respect to any Eurodollar Rate Advances, the Required Lenders notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate Advances for such Interest Period, the Administrative Agent shall forthwith so notify the Borrower and the Lenders, whereupon (i) each Eurodollar Rate Advance will automatically, on the final day of the then existing Interest Period therefor, Convert into a Base Rate Advance, and (ii) the obligation of the Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist.

Alenco - Amended and Restated Credit Agreement

Conversion of Base Rate Advances into Eurodollar Rate Advances shall be in an amount not less than $1,000,000 and no Conversion of any Advances shall result in more separate Borrowings than permitted under Section 2.02(b). Each such notice of a Conversion shall, within the restrictions specified above, specify (i) the date of such Conversion, (ii) the Revolving Credit Advances to be Converted and (iii) if such Conversion is into Eurodollar Rate Advances, the duration of the initial Interest Period for each such Advance. Each notice of Conversion shall be irrevocable and binding on the Borrower.

The Borrower may, upon at least one Business Day’s notice to the Administrative Agent not later than 12:00 noon (New York City time) for Base Rate Advances, and upon at least two (2) Business Days’ notice to the Administrative Agent not later than 12:00 noon (New York City time) for Eurodollar Rate Advances, stating the proposed date and aggregate principal amount of the prepayment, and if such notice is given the Borrower shall, prepay the outstanding principal amount of the Revolving Credit Advances or Swing Line Advances, as the case may be, comprising part of the same Borrowing in whole or ratably in part, together with accrued interest to the date of such prepayment on the principal amount prepaid; provided, however, (a) each partial prepayment of (i) Revolving Credit Advances shall be in an aggregate principal amount of $1,000,000 or an integral multiple of $1,000,000 in excess thereof and (ii) Swing Line Advances shall be in an aggregate principal amount of $1,000,000 or an integral multiple of $500,000 in excess thereof and (b) in the event of any such prepayment of a Eurodollar Rate Advance, the Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant to Section 8.04(c).

SECTION 2.12. Increased Costs. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation subsequent to the date hereof or (ii) the compliance with any written guideline or request from any central bank or other governmental authority (whether or not having the force of law), announced, issued, made or imposed subsequent to the date hereof, there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Advances or to any Issuing Bank of agreeing to issue or issuing or maintaining Letters of Credit (excluding for purposes of this Section 2.12 any such increased costs resulting from (i) Taxes or Other Taxes (as to which Section 2.15 shall govern) ,(ii) changes in the basis of taxation of overall net income or overall gross income (or the basis of taxation on capital, branch profits or franchises imposed in lieu of net or gross income taxes) by the United States or by the foreign jurisdiction or state under the laws of which such Lender or Issuing Bank is organized or has its Applicable Lending Office or any political subdivision thereof and (iii) FATCA), then the Borrower shall from time to time, upon demand by such Lender or Issuing Bank (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender or Issuing Bank additional amounts sufficient to compensate such Lender or Issuing Bank for such increased cost. A certificate as to the amount of such increased cost, submitted to the Borrower and the Administrative Agent by such Lender or Issuing Bank, shall be conclusive and binding for all purposes, absent manifest error; provided, however, that the Borrower shall not be obligated to pay to such Lender such amounts unless such Lender at such time shall be generally assessing such amounts on a non-discriminatory basis against borrowers under agreements having provisions similar to this paragraph.

(b) If any Lender Party acting reasonably determines that compliance with any law or regulation or any written guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender Party or any corporation controlling such Lender Party and that the amount of such capital is increased by or based upon the existence of such Lender Party’s Revolving Credit Commitment, Swing Line Sub-Commitment or Letter of Credit Sub-Commitment or

Alenco - Amended and Restated Credit Agreement

other commitments of such type or is increased by or, if applicable, based upon the issuance by such Issuing Bank of any Letter of Credit and other letters of credit of such type, then, upon demand by such Lender Party (with a copy of such demand to the Administrative Agent), the Borrower shall pay to the Administrative Agent for the account of such Lender Party, from time to time as specified by such Lender Party, additional amounts sufficient to compensate such Lender Party or such corporation in the light of such circumstances, to the extent that such Lender Party reasonably determines such increase in capital to be allocable to the existence of such Lender Party’s Revolving Credit Commitment, Swing Line Sub-Commitment or Letter of Credit Sub-Commitment or outstanding Letters of Credit; provided, however, that the Borrower shall not be obligated to pay to such Lender such amounts unless such Lender at such time shall be generally assessing such amounts on a non-discriminatory basis against borrowers under agreements having provisions similar to this paragraph. A certificate as to such amounts, submitted to the Borrower and the Administrative Agent by such Lender Party, shall be conclusive and binding for all purposes, absent manifest error in the calculation of such amounts.

(c) Failure or delay on the part of any Lender Party to demand compensation pursuant to this Section shall not constitute a waiver of such Lender Party’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender Party pursuant to this Section for any increased costs incurred or reductions suffered more than three months prior to the date that such Lender Party notifies the Borrower of the circumstances giving rise to such increased costs or reductions, and of such Lender Party’s intention to claim compensation therefor (except that, if the circumstance giving rise to such increased costs or reductions is retroactive, then the three-month period referred to above shall be extended to include the period of retroactive effect thereof).

(d) For the avoidance of doubt, this Section 2.12 shall apply to all requests, rules, guidelines or directives concerning capital adequacy (i) issued in connection with the Dodd-Frank Wall Street Reform and Consumer Protection Act and (ii) promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, regardless of the date enacted, adopted or issued.

SECTION 2.13. Illegality. Notwithstanding any other provision of this Agreement, if any Lender Party shall notify the Administrative Agent that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or any central bank or other governmental authority asserts that it is unlawful, for any Lender Party or its Eurodollar Lending Office to perform its obligations hereunder to make Eurodollar Rate Advances or to fund or maintain Eurodollar Rate Advances hereunder, (a) each Eurodollar Rate Advance will automatically, upon such demand, Convert into a Base Rate Advance and (b) the obligation of the Lenders to make Eurodollar Rate Advances or to Convert Advances into Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower and the Lender Parties that the circumstances causing such suspension no longer exist.

SECTION 2.14. Payments and Computations. (a) The Borrower shall make each payment hereunder, irrespective of any right of counterclaim or set-off, not later than 12:00 noon (New York City time) on the day when due in United States Dollars to the Administrative Agent at the Administrative Agent’s Account in same day funds. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal or interest or commitment fees ratably (other than amounts payable pursuant to Section 2.05(b), 2.12, 2.15, 2.21 or 8.04(c)) to the Lenders or Issuing Banks to which such amounts shall be payable for the account of their respective

Alenco - Amended and Restated Credit Agreement

Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or Issuing Bank to such Lender or Issuing Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information contained therein in the Register pursuant to Section 8.07(c), from and after the effective date specified in such Assignment and Assumption, the Administrative Agent shall make all payments hereunder in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender and Issuing Bank, if and to the extent payment owed to such Lender or Issuing Bank is not made when due hereunder, to charge from time to time against any or all of the Borrower’s accounts with such Lender or Issuing Bank any amount so due.

(c) All computations of interest based on the rate of interest referred to in clause (a) of the definition of the term “Base Rate” in Section 1.01 shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the rate of interest referred to in clause (b) or (c) of the definition of the term “Base Rate” in Section 1.01 and of fees shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the final day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fee, as the case may be; provided, however, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Lenders or the Issuing Banks hereunder that the Borrower will not make such payment in full, the Administrative Agent may assume that the Borrower has made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender or Issuing Bank on such due date an amount equal to the amount then due such Lender or Issuing Bank. If and to the extent the Borrower shall not have so made such payment in full to the Administrative Agent, each Lender or Issuing Bank shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender or Issuing Bank together with interest thereon, for each day from the date such amount is distributed to such Lender or Issuing Bank until the date such Lender or Issuing Bank repays such amount to the Administrative Agent, at the Federal Funds Rate.

SECTION 2.15. Taxes. (a) Subject to Sections 2.15(e), (f) and (h), any and all payments by the Borrower under any Document and Loan Document shall be made, in accordance with Section 2.14, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto imposed by the

Alenco - Amended and Restated Credit Agreement

United States or any political subdivision or taxing authority thereof or therein or any other jurisdiction from or through which the Borrower makes payment hereunder, excluding, (i) in the case of each Lender Party and the Administrative Agent, taxes imposed on its overall net income or capital, branch profits taxes and franchise taxes imposed on it in lieu of net income taxes by the jurisdiction under the laws of which such Lender Party or the Administrative Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Lender Party, taxes imposed on its overall net income or capital, branch profits taxes and franchise taxes imposed on it in lieu of net income taxes, by the jurisdiction in which the principal office or such Lender Party’s Applicable Lending Office is located or any political subdivision thereof or any taxes imposed by Sections 864(c)(7) or 877 of the Internal Revenue Code, or any similar provision of law and (ii) any United States withholding tax imposed under FATCA (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments under any Document or Loan Document being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable under any Document or Loan Document to any Lender Party or the Administrative Agent, or, if the Administrative Agent shall be required by law to deduct any Taxes from or in respect of any sum paid or payable under any Document or Loan Document to any Lender Party, (i) the sum payable by the Borrower shall be increased by the Borrower as may be necessary so that, after making all required deductions (including deductions, whether by the Borrower or the Administrative Agent, applicable to additional sums payable under this Section 2.15) such Lender Party and the Administrative Agent receive an amount equal to the sum they each would have received had no such deductions been made (for example, and without limitation of the generality of the foregoing, if the sum paid or payable hereunder from or in respect of which the Borrower or the Administrative Agent shall be required to deduct any Taxes is interest, the interest payable by such Borrower shall be increased by the Borrower as may be necessary so that, after making all required deductions (including deductions applicable to additional interest), such Lender Party and the Administrative Agent each receive interest equal to the interest they each would have received had no such deduction been made), (ii) the Borrower (or, as the case may be and as required by applicable law, the Administrative Agent) shall make such deductions and (iii) the Borrower (or, as the case may be and as required by applicable law, the Administrative Agent) shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made under any Document or Loan Document or from the execution, delivery or registration of, performing under, or otherwise with respect to, any Document or Loan Document (hereinafter referred to as “Other Taxes”).

(c) Subject to Sections 2.15(e), (f) and (h), the Borrower shall indemnify each Lender Party and the Administrative Agent for and hold each Lender Party and the Administrative Agent harmless against the full amount of Taxes or Other Taxes imposed on or paid by such Lender Party or the Administrative Agent (as the case may be) and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date such Lender Party or the Administrative Agent (as the case may be) makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes by or on behalf of the Borrower, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing such payment to the extent such a receipt is

Alenco - Amended and Restated Credit Agreement

issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent.

(e) (i) Each Lender Party that is not a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender Party and on the date of the Assignment and Assumption pursuant to which it becomes a Lender Party in the case of each other Lender Party, and from time to time thereafter as requested in writing by the Borrower or upon the obsolescence, expiration or invalidity of any form previously delivered by such Lender Party (but only so long as such Lender Party remains lawfully able to do so), shall provide each of the Administrative Agent and the Borrower with two original Internal Revenue Service forms W-8BEN or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Lender Party is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement and, in the case of a Lender Party claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code with respect to payments of “portfolio interest,” a statement substantially in the form of Exhibit H. If the form provided by a Lender Party at the time such Lender Party first becomes a party to this Agreement indicates a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender Party provides the appropriate forms certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes for periods governed by such form; provided, however, if at the date of the Assignment and Assumption pursuant to which a Lender Party assignee becomes a party to this Agreement, the Lender Party assignor was entitled to payments under subsection (a) in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Lender Party assignee on such date. If any form or document referred to in this subsection (e) requires the disclosure of information, other than information necessary to compute the tax payable and information required on the date hereof by Internal Revenue Service form W-8BEN or W-8ECI, that the Lender Party reasonably considers to be confidential, the Lender Party shall give notice thereof to the Borrower and shall not be obligated to include in such form or document such confidential information.

(ii) If a payment made to a Lender Party would be subject to United States federal withholding tax imposed by FATCA if such Lender Party were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender Party shall deliver to the Borrower, at the time or times prescribed by law and at such time or times reasonably requested in writing by the Borrower, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested in writing by the Borrower as may be necessary for the Borrower to comply with its obligations under FATCA, to determine that such Lender Party has complied with such Lender Party’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. For purposes of this Section 2.15(e)(ii) FATCA shall include any Treasury regulations or interpretations thereof.

(f) For any period with respect to which a Lender Party has failed to provide the Borrower with the appropriate form, certificate or other document described in Section 2.15(e) (other than if such failure is due to a change in law, or in the interpretation or application thereof occurring subsequent to the date on which a form, certificate or other document originally was required to be

Alenco - Amended and Restated Credit Agreement

provided, or if such form, certificate or other document otherwise is not required under subsection (e) above), such Lender Party shall not be entitled to indemnification under Section 2.15(a) or Section 2.15(c) with respect to Taxes imposed by the United States by reason of such failure; provided, however, should a Lender Party become subject to Taxes because of its failure to deliver a form, certificate or other document required hereunder, the Borrower shall take such steps as the Lender Party shall reasonably request to assist the Lender Party to recover such Taxes.

(g) In the event that an additional payment is made under Section 2.15(a) or Section 2.15(c) for the account of any Lender Party and such Lender Party, in its sole discretion, determines that it has finally and irrevocably received or been granted a credit against or release or remission for, or repayment of, any tax paid or payable by it in respect of or calculated with reference to the deduction or withholding giving rise to such additional payment, such Lender Party shall, to the extent that it determines that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower such amount as such Lender Party shall, in its sole discretion, have determined to be attributable to such deduction or withholding and which will leave such Lender Party (after such payment) in no worse position than it would have been in if the Borrower had not been required to make such deduction or withholding; provided that the Borrower, upon the request of such Lender Party, agrees to pay the amount paid over to the Borrower (plus penalties, interest and other reasonable charges) to such Lender Party in the event such Lender Party is required to repay such credit, relief, remission or repayment to the applicable taxation authority. Nothing herein contained shall interfere with the right of a Lender Party to arrange its tax affairs in whatever manner it thinks fit nor oblige any Lender Party to claim any tax credit or to disclose any information relating to its tax affairs or any computations in respect thereof or require any Lender Party to do anything that would prejudice its ability to benefit from any other credits, reliefs, remissions or repayments to which it may be entitled.

(h) Upon the request of Borrower or upon the obsolescence, expiration or invalidity of any form previously delivered by such Lender Party, any Lender Party that is a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code shall deliver to the Borrower two original Internal Revenue Service form W-9 or any successor or other form prescribed by the Internal Revenue Service. If any Lender Party fails to deliver Internal Revenue Service form W-9 or any subsequent versions thereof or successors thereto as required herein, then the Borrower may withhold from any payment to such Lender Party the applicable backup withholding tax imposed by the Internal Revenue Code and remit such amount to the applicable taxation authority if required by law, without reduction, and such Lender Party shall not be entitled to any additional amounts under this Section 2.15 with respect to Taxes imposed by the United States by reason of such failure.

SECTION 2.16. Sharing of Payments, Etc. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Advances or other obligations hereunder resulting in such Lender receiving payment of a proportion of the aggregate amount of its Advances and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Advances and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Advances and other amounts owing them; provided that:

Alenco - Amended and Restated Credit Agreement

(i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (y) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Advances or participations in L/C Obligations to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

The Borrower agrees that any Lender so purchasing a participation from another Lender by delivering payment pursuant to this Section 2.16 may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

SECTION 2.17. Mitigation Obligations; Replacement of Lenders. (a) Designation of a Different Lending Office. If any Lender requests compensation under Section 2.12, asserts a claim under Section 2.13 or requires the Borrower to pay additional amounts to any Lender or any governmental authority for the account of any Lender pursuant to Section 2.15, then such Lender shall (at the request of the Borrower) use reasonable efforts to designate a different lending office for funding or booking its Advances hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the good faith judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.12 or 2.15 (or eliminate any claim under Section 2.13), as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise cause more than an insubstantial disadvantage to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. So long as no Default is continuing, if (i) the Borrower becomes obligated to pay additional amounts to any Lender pursuant to Section 2.12 or 2.15, (ii) any Eurodollar Rate Advance is required to be Converted into a Base Rate Advance pursuant to Section 2.13, in the case of clause (i) or this clause (ii) as a result of any condition described in such Sections that is not generally applicable to all the Lenders, (iii) any Lender fails to extend the Termination Date in accordance with Section 8.11, (iv) any Lender is a Defaulting Lender or (v) any Lender does not approve any consent, waiver or amendment that (x) requires the approval of all affected Lenders in accordance with the terms of Section 8.01 and (y) has been approved by the Required Lenders (a “Non-Approving Lender”), then the Borrower may, at its sole expense and effort, within fifteen (15) days of being notified of such condition or circumstance, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 8.07), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(i) the Borrower shall have paid to the Administrative Agent the assignment fee (if any) specified in Section 8.07;

Alenco - Amended and Restated Credit Agreement

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Advances, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 8.04(c)) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(iii) in the case of any such assignment resulting from a claim for compensation under Section 2.12 or payments required to be made pursuant to Section 2.15, such assignment will result in a reduction in such compensation or payments thereafter;

(iv) such assignment does not conflict with applicable law; and

(v) in the case of any assignment resulting from a Lender becoming a Non-Approving Lender, the applicable assignee shall have consented to the applicable amendment, waiver or consent.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.18. Use of Proceeds. (a) Subject to the provisions of subsection (b) of this Section 2.18, the proceeds of the Advances shall be available (and the Borrower agrees that it shall use such proceeds) solely for general corporate purposes of the Borrower (including, without limitation, the making of loans by the Borrower to any of its Affiliates, provided that such Affiliate is a Wholly-Owned Subsidiary) and its Subsidiaries; provided, however, that, except as specifically provided in, and in accordance with the terms of, Section 5.02(d), none of such proceeds shall be used by the Borrower or any of its Subsidiaries or Affiliates to acquire any equity security of any issuer pursuant to a general solicitation, exchange offer or tender offer for, or pursuant to a request or invitation for tenders of, such security unless the board of directors of such issuer shall have approved and recommended such general solicitation, exchange offer, tender offer or request or invitation for tender at or prior to the initiation thereof.

(b) Notwithstanding anything to the contrary contained herein, the Borrower agrees that none of the proceeds of the Advances or drawing under any Letter of Credit shall be used by the Borrower or any of its Subsidiaries, directly or indirectly, for the purpose, whether immediate, incidental or ultimate, of buying or carrying any Margin Stock.

SECTION 2.19. Increase of Commitments (a) The Borrower may, at any time on or after a Section 2.19 Effective Date, but in any event not more than two times during any calendar year, make a written request (an “Increase Request”) to the Administrative Agent (who shall forward a copy to each Lender) that the Revolving Credit Commitments of the Lenders be increased in (i) an aggregate amount for each Increase Request of not less than $25,000,000 and integral multiples of $1,000,000 in excess thereof (such amount being the “Requested RCC Increase”) and (ii) an aggregate amount for such Increase Request, together with the aggregate amount by which the Revolving Credit Commitments of the Lenders were previously increased pursuant to this Section 2.19, if any, not to exceed $400,000,000. Such Increase Request shall include (A) a certification by a Senior Financial Officer of the Borrower that no Default has occurred and is continuing and all representations and

Alenco - Amended and Restated Credit Agreement

warranties contained herein are true and correct in all material respects on and as of the date of the Increase Request (it being understood and agreed that any representation or warranty which expressly refers by its terms to a specified date shall be required to be true and correct in all material respects only as of such date) and (B) the written consent of the Guarantor to such Increase Request together with a written confirmation, in a form reasonably acceptable to the Administrative Agent, by the Guarantor that the Amended and Restated Guaranty applies to any increase of a Lender’s Revolving Credit Commitment and any amounts made available by an Eligible Assignee pursuant to the terms hereof. Any such increase in Revolving Credit Commitments shall be effective as of a date (the “Increase Date”) specified in the related Increase Request that is (I) prior to the Termination Date and (II) at least 15 Business Days after the date of such Increase Request. Each Increase Request shall specify the date by which Lenders who wish to increase their Revolving Credit Commitments must consent to such increase, which date (the “Commitment Date”) shall be no later than 5 Business Days prior to the related Increase Date. Each Lender that is willing to increase its Revolving Credit Commitment (each such Lender, an “Increasing Lender”) shall notify the Administrative Agent on or prior to the Commitment Date of the amount by which it is willing to increase its Revolving Credit Commitment, which amount shall not exceed the amount specified in the relevant Increase Request. Any Lender that does not notify the Administrative Agent by the Commitment Date shall be deemed to have elected not to increase its Commitment. No Lender shall be obligated to increase its Revolving Credit Commitment pursuant to this Section 2.19 and any such increase shall be in the sole discretion of each Lender and shall be subject to the consent of the Administrative Agent, the Issuing Banks and the Swing Line Bank, such consent not to be unreasonably withheld or delayed. If the Increasing Lenders notify the Administrative Agent that they are willing to increase the amount of their respective Revolving Credit Commitments by an aggregate amount that exceeds the amount of the requested increase, the requested increase shall be allocated among the Increasing Lenders ratably in accordance with the amount by which they offered to increase their respective Revolving Credit Commitments on or prior to the Commitment Date.

(b) Promptly following each Commitment Date, the Administrative Agent shall notify the Borrower as to the amount, if any, by which the Increasing Lenders are willing to participate in the requested increase. If the aggregate amount by which the Increasing Lenders are willing to increase their Revolving Credit Commitments on any such Commitment Date is less than the requested amount, then any one or more Eligible Assignees designated by the Borrower that agree to provide Revolving Credit Commitments may become party to this Agreement by executing and delivering, together with the Borrower, an Accession Letter Agreement pursuant to which such Eligible Assignee shall become a party to this Agreement and, to the extent provided therein, shall have the rights and obligations of a Lender hereunder; provided that each such Eligible Assignee shall provide a Revolving Credit Commitment in a minimum amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof.

(c) On each Increase Date, (i) each Eligible Assignee that accepts an offer to participate in a requested Revolving Credit Commitment increase in accordance with Section 2.19(b) shall become a Lender party to this Agreement as of such Increase Date and the Revolving Credit Commitment of each Increasing Lender shall be increased as of such Increase Date by the amount set forth in its notice delivered to the Administrative Agent in accordance with Section 2.19(a) (or by the amount allocated to such Lender pursuant to the final sentence of Section 2.19(a) and (ii)) if on such date there are Advances outstanding, appropriate adjustments shall be made among the Lenders to cause each Lender to hold its Pro Rata Share of such outstanding Advances as of the Increase Date.

Alenco - Amended and Restated Credit Agreement

(d) The Borrower may from time to time in accordance with Section 2.19(a) make an Increase Request on and after a date (each such date, the “Section 2.19 Effective Date”) on which the Administrative Agent shall have received the following in respect of the Requested RCC Increase set forth in such Increase Request, each dated as of the applicable Section 2.19 Effective Date, in form and substance reasonably satisfactory to the Administrative Agent and in sufficient copies for each Lender:

(i) Certified copies of the resolutions of the board of directors of the Borrower approving the transactions contemplated by the applicable Requested RCC Increase, and of all documents evidencing other necessary corporate action and governmental approvals, if any, with respect to the transactions contemplated by this Section 2.19.

(ii) A certificate of the Secretary or an Assistant Secretary of the Borrower certifying the names and true signatures of the officers of the Borrower authorized to sign an Increase Request and the other documents to be delivered by the Borrower under this Section 2.19.

(iii) An Amended and Restated Guaranty, duly executed by the Guarantor in respect of all obligations of the Borrower under this Agreement after giving effect to the Requested RCC Increase set forth in such Increase Request.

(iv) Certified copies of the resolutions of the Board of Directors of the Guarantor authorizing the applicable Amended and Restated Guaranty and authorizing the guaranty of the Requested RCC Increase and all other obligations of the Borrower under this Agreement, including without limitation, any obligations of the Borrower arising under this Section 2.19, and of all documents evidencing other necessary corporate action and governmental approvals, if any, with respect to the applicable Amended and Restated Guaranty and the transactions contemplated by this Section 2.19.

(v) A certificate of the Secretary or an Assistant Secretary of the Guarantor certifying the names and true signatures of the officers of the Guarantor authorized to sign the applicable Amended and Restated Guaranty and the other documents to be delivered by the Guarantor hereunder.

(vi) An opinion of internal counsel or an Associate General Counsel for, or acting on behalf of, the Borrower and the Guarantor, substantially in the form of Exhibit D-1.

(vii) An opinion of New York counsel to each of the Borrower and the Guarantor, substantially in the form of Exhibit D-2 or otherwise in a form reasonably satisfactory to the Administrative Agent.

SECTION 2.20. Evidence of Debt (a) Each Lender Party shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender Party resulting from each Advance owing to such Lender Party from time to time, including the amounts of principal and interest payable and paid to such Lender Party from time to time hereunder.

(b) The Register maintained by the Administrative Agent pursuant to Section 8.07(c) shall include a control account, and a subsidiary account for each Lender Party, in which accounts

Alenco - Amended and Restated Credit Agreement

(taken together) shall be recorded (i) the date, amount and type of each Advance made hereunder, and, if appropriate, the Interest Period applicable thereto, (ii) the terms of each Assignment and Assumption and Accession Letter Agreement delivered to and accepted by it, (iii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender Party hereunder and (iv) the amount of any sum received by the Administrative Agent from the Borrower hereunder and each Lender Party’s share thereof.

(c) Entries made in good faith by the Administrative Agent in the Register pursuant to subsection (b) above, shall be prima facie evidence of the amount of principal and interest due and payable or to become due and payable from the Borrower to each Lender Party under this Agreement, absent manifest error; provided, however, that the failure of the Administrative Agent to make an entry, or any finding that an entry is incorrect, in the Register shall not limit or otherwise affect the obligations of the Borrower under this Agreement.

SECTION 2.21. Defaulting Lenders. (a) If a Lender becomes, and during the period it remains, a Defaulting Lender, the following provisions shall apply:

(i) such Defaulting Lenders’ Pro Rata Share of the L/C Obligations and Swing Line Advances will, subject to the limitation in the first proviso below, automatically be reallocated (effective on the day such Lender becomes a Defaulting Lender) among the Non-Defaulting Lenders pro rata in accordance with their respective Commitments; provided that (A) the sum of each Non-Defaulting Lender’s aggregate principal amount of Revolving Credit Advances and allocated share of the L/C Obligations and Swing Line Advances may not in any event exceed the Revolving Credit Commitment of such Non-Defaulting Lender as in effect at the time of such reallocation and (B) neither such reallocation nor any payment by a Non-Defaulting Lender pursuant thereto will constitute a waiver or release of any claim the Borrower, the Administrative Agent or any Lender Party may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender;

(ii) to the extent that (a) any portion (the “unreallocated portion”) of the Defaulting Lender’s share of the L/C Obligations and Swing Line Advances cannot be so reallocated, whether by reason of the first proviso in clause (i) above or otherwise and (b) the Defaulting Lender has not made an assignment and delegation pursuant to Section 2.17(b)(iv), in each case within 20 days after receipt by the Borrower of written notice by the Administrative Agent that such Lender has become a Defaulting Lender, then the Borrower will, not later than five Business Days after demand by the Administrative Agent (at the direction of an Issuing Bank and/or a Swing Line Bank), (A) Cash Collateralize the obligations of the Borrower in respect of such L/C Obligations or Swing Line Advances in an amount at least equal to the aggregate amount of the unreallocated portion of such L/C Obligations or Swing Line Advances, or (B) make other arrangements satisfactory to the Administrative Agent, each Issuing Bank and each Swing Line Bank, as the case may be, in their sole discretion to protect them against the risk of non-payment by such Defaulting Lender; and

(iii) amounts deposited pursuant to clause (ii) above at the request of any Issuing Bank or any Swing Line Bank shall be applied by the Administrative Agent to reimburse such Issuing Bank or such Swing Line Bank for any participations required to

Alenco - Amended and Restated Credit Agreement

be funded by such Defaulting Lender. In the event amounts so deposited with respect to any such Defaulting Lender for the benefit of any Issuing Bank or any Swing Line Bank exceed the Pro Rata Share of such Defaulting Lender attributable to the Letters of Credit issued by such Issuing Bank or the Pro Rata Share of such Defaulting Lender attributable to the Swing Line Advances, as the case may be, the Administrative Agent shall give prompt notice thereof to the Borrower and, unless otherwise specified in writing by the Borrower, shall promptly return to the Borrower cash in the amount of such excess.

(iv) if the Borrower Cash Collateralizes any portion of such Defaulting Lenders share of the L/C Obligations pursuant to clause (ii) above, the Borrower shall not be required to pay any fees to such Defaulting Lender under Section 2.05(b) with respect to such Defaulting Lender’s share of the L/C Obligations during the period that such Defaulting Lender’s share of the L/C Obligations is Cash Collateralized;

(v) any amount paid by the Borrower (which, for the avoidance of doubt, shall not include any amounts set off by the Borrower pursuant to Section 8.05(b)) or otherwise received by the Administrative Agent for the account of a Defaulting Lender under this Agreement (whether on account of principal, interest, fees, indemnity payments or other amounts) will not be paid or distributed to such Defaulting Lender, but will instead be retained by the Administrative Agent in a segregated non-interest bearing account until (subject to Section 2.21(c)) the termination of the Revolving Credit Commitments and payment in full of all obligations of the Borrower hereunder and will be applied by the Administrative Agent, to the fullest extent permitted by law, to the making of payments from time to time in the following order of priority: first to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent under this Agreement, second to the payment of any amounts owing by such Defaulting Lender to an Issuing Bank or a Swing Line Bank (pro rata as to the respective amounts owing to each of them) under this Agreement, third to the payment of post-default interest and then current interest due and payable to the Lenders hereunder other than Defaulting Lenders, ratably among them in accordance with the amounts of such interest then due and payable to them, fourth to the payment of fees then due and payable to the Non-Defaulting Lenders hereunder, ratably among them in accordance with the amounts of such fees then due and payable to them, fifth to pay principal then due and payable to the Non-Defaulting Lenders hereunder ratably in accordance with the amounts thereof then due and payable to them, sixth to the ratable payment of other amounts then due and payable to the Non-Defaulting Lenders, and seventh after the termination of the Revolving Credit Commitments and payment in full of all obligations of the Borrower hereunder, to pay amounts owing under this Agreement to such Defaulting Lender or as a court of competent jurisdiction may otherwise direct. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post cash collateral pursuant to this Section 2.21 shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

In furtherance of the foregoing, if any Lender becomes, and during the period it remains, a Defaulting Lender and the Borrower fails to comply with its obligations under Section 2.21(a)(ii) within the time periods set forth in such section, each Issuing Bank and each Swing Line Bank is hereby authorized by the Borrower (which authorization is irrevocable and coupled with an interest) to give, in its discretion,

Alenco - Amended and Restated Credit Agreement

through the Administrative Agent, Notices of Borrowing pursuant to Section 3.02 in such amounts as may be required to fulfill the Borrower’s obligations under Section 2.21(a)(ii)(A).

(b) No Revolving Credit Commitment of any Lender shall be increased or otherwise affected, and, except as otherwise expressly provided in this Section 2.21, performance by the Borrower of its obligations shall not be excused or otherwise modified as a result of the operation of this Section 2.21. The rights and remedies against a Defaulting Lender under this Section 2.21 are in addition to any other rights and remedies which the Borrower, the Administrative Agent, any Issuing Bank, any Swing Line Bank or any Lender may have against such Defaulting Lender.

(c) If the Borrower, the Administrative Agent, the Issuing Bank and the Swing Line Bank agree in writing in their discretion that a Lender that is a Defaulting Lender or a Potential Defaulting Lender should no longer be deemed to be a Defaulting Lender or Potential Defaulting Lender, as the case may be, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any amounts then held in the segregated account referred to in Section 2.21(a)(iii)), such Lender will, to the extent applicable, purchase such portion of outstanding Advances of the other Lenders and/or make such other adjustments as the Administrative Agent may determine to be necessary to cause the Revolving Credit Commitments, Letter of Credit Sub-Commitments and Swing Line Sub-Commitments of the Lenders to be on a pro rata basis in accordance with their respective Commitments, whereupon such Lender will cease to be a Defaulting Lender or Potential Defaulting Lender and will be a Non-Defaulting Lender (and such exposure of each Lender will automatically be adjusted on a prospective basis to reflect the foregoing); provided, that no adjustments will be made retroactively with respect to payments made by or on behalf of the Borrower while such Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender or Potential Defaulting Lender to Non-Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from such Lender’s having been a Defaulting Lender or Potential Defaulting Lender.

Alenco - Amended and Restated Credit Agreement

become, outstanding after giving effect to such permanent reduction in the total amount of the Commitments.

(c) Transfer of Assets. Except in the ordinary course of business, transfer or permit its Restricted Subsidiaries to transfer, for less than fair market value, assets to a corporation which would be a Subsidiary but for the fact that it has Publicly Traded Securities.

(d) Use of Proceeds. The Borrower shall use, and shall cause its Subsidiaries to use, the Proceeds of the Advances solely as set forth in Section 2.18 herein. Subject to the provisions of Section 2.18(b), the Borrower may utilize the proceeds of the Advances to, or to provide funds to any Subsidiary or to make a loan to any of its Affiliates (provided that such Affiliate is a Wholly-Owned Subsidiary) to, finance an offer to acquire (which shall include an offer to purchase securities, solicitation of an offer to sell securities, an acceptance of an offer to sell securities, whether or not the offer to sell was solicited, or any combination of the foregoing) outstanding securities of any Person (the “Target”) which constitutes a “take-over bid” (or any other similar term) pursuant to applicable securities legislation or other Applicable Law (a “Take-over”) on the terms set forth below:

The Borrower must either:

(i) prior to or concurrently with delivery to the Administrative Agent of any Notice of Borrowing or any Notice of Issuance, the proceeds of which are to be used to finance such Take-over, provide to the Administrative Agent evidence reasonably satisfactory to the Administrative Agent that the board of directors or like body of the Target, or the holders of the requisite number of securities of the Target as are required to approve such Take-over to ensure the successful completion of such Take-over under Applicable Law, has or have approved, accepted, or recommended to security holders acceptance of, the Take-over; or

(ii) follow the following steps:

(A) at least five (5) Business Days prior to the delivery to the Administrative Agent of any Notice of Borrowing or Notice of Issuance, intended to be used to finance such Take-over, the President or a Senior Financial Officer of the Borrower shall advise the Administrative Agent about the particulars of such Take-over in sufficient detail, and the Administrative Agent shall promptly advise an appropriate officer of each Lender of the particulars of such Take-over in sufficient detail to enable each such Lender to determine whether it has a conflict of interest if Advances from such Lender are used by the Borrower to finance such Take-over;

(B) within three (3) Business Days of being so advised by the Administrative Agent, each such Lender shall notify the Administrative Agent of such Lender’s determination as to whether a conflict of interest exists (such determination to be made by such Lender in the exercise of its sole discretion, having regard to such considerations as it deems appropriate); provided that in the event such Lender does not so notify the Administrative Agent within such three (3) Business Day period, such Lender shall be deemed to have notified the Administrative Agent that it has no such conflict of interest; and

Alenco - Amended and Restated Credit Agreement

(C) the Administrative Agent shall promptly notify the President or a Senior Financial Officer of the Borrower of each such Lender’s determination.

In the event that any such Lender has such a conflict of interest (an “Affected Lender”), then upon the Administrative Agent so notifying the Borrower, the Affected Lender shall have no obligation to provide any Advances to finance such Take-over, notwithstanding any other provision of this Agreement to the contrary; provided however that each other relevant Lender which has, or is deemed to have, no such conflict of interest (a “Non-Affected Lender”) shall have an obligation, up to the amount of its Revolving Credit Commitment, to provide Advances to finance such Take-over, and Advances to finance such Take-over shall be provided by each Non-Affected Lender in accordance with the ratio, determined prior to the provision of any Advances to finance such Take-over, that the Commitment of such Non-Affected Lender bears to the aggregate of the Commitments of all the Non-Affected Lenders hereunder. If Advances are used to finance a Take-over and there are Affected Lenders, subsequent Advances shall be funded first by Affected Lenders, and subsequent repayments shall be applied first to Non-Affected Lenders, in each case, until such time as the proportion that the amount of the aggregate principal amount of the Advances made by each Non-Affected Lender bears to the amount of the aggregate principal amount of the Advances of all Lenders is equal to such proportion which would have been in effect but for the application of this Section 5.02(d).

ARTICLE VII

THE ADMINISTRATIVE AGENT

SECTION 7.01. Appointment and Authority Each Lender Party (in its capacities as a Lender, the Swing Line Bank (if applicable) and an Issuing Bank (if applicable)) hereby irrevocably appoints Citibank to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article are solely for the benefit of the Administrative Agent and the Lender Parties, and the Borrower shall not have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create or reflect only an administrative relationship between contracting parties.

SECTION 7.02. Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender Party as any other Lender Party and may exercise the same as though it were not the Administrative Agent, and the term “Lender Party” or “Lender Parties” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lender Parties.

SECTION 7.03. Exculpatory Provisions. (a) The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the Administrative Agent:

(i) shall not be subject to any fiduciary or other implied duties, regardless of whether a 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 or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents); provided that the Administrative Agent shall not be required to take any action that, in its reasonable opinion or on the reasonable advice of counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any debtor relief law or that may effect a forfeiture,

Alenco - Amended and Restated Credit Agreement

modification or termination of property of a Defaulting Lender in violation of any debtor relief law; and

(iii) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

(b) The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Sections 8.01 and 6.01), or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until notice describing such Default is given to the Administrative Agent in writing by the Borrower or a Lender Party.

(c) The Administrative 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 or any other Loan Document, (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 or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article II or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

SECTION 7.04. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, 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. The Administrative 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. In determining compliance with any condition hereunder to the making of an Advance, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or an Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to such Lender or Issuing Bank unless the Administrative Agent shall have received notice to the contrary from such Lender or Issuing Bank prior to the making of such Advance or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), 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 7.05. Indemnification. The Lender Parties severally agree to indemnify the Administrative Agent (in such capacity and to the extent not reimbursed by the Borrower), ratably according to the respective amounts of their Revolving Credit Commitments, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or

Alenco - Amended and Restated Credit Agreement

disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of any Document or any action taken or omitted thereby under any Document (collectively, the “Indemnified Costs”), provided that no Lender Party shall be liable for any portion of the Indemnified Costs resulting from the Administrative Agent’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender Party agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, any Document, to the extent that the Administrative Agent is not reimbursed for such expenses by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by the Administrative Agent, either Syndication Agent, either Documentation Agent, either Lead Arranger, any Lender Party or a third party. The respective obligations of the Lenders under this Section are several and not joint and no Lender shall be responsible for the failure of any other Lender to satisfy its obligations hereunder.

SECTION 7.06. Resignation of Administrative Agent. (a) The Administrative Agent may at any time give written notice of its resignation to the Lender Parties and the Borrower and may be removed at any time with or without cause by the Required Lenders. Upon receipt of any such notice of resignation or removal, the Required Lenders shall have the right with the prior approval of the Borrower so long as no Default shall have occurred and be continuing (which approval will not be unreasonably withheld or delayed), to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 60 days after the retiring Administrative Agent gives notice of its resignation or the Required Lenders’ removal of the retiring Administrative Agent (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”), then the retiring Administrative Agent may (but shall not be obligated to), on behalf of the Lender Parties, appoint a successor Administrative Agent meeting the qualifications set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b) With effect from the Resignation Effective Date (1) the retiring or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Administrative Agent on behalf of the Lender Parties hereunder, the retiring or removed Administrative Agent shall continue to hold such collateral security until such time as a successor Administrative Agent is appointed) and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender Party directly, until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Administrative Agent, and the retiring or removed Administrative Agent shall be discharged from all of its duties and obligations hereunder and under the other Loan Documents. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring or removed Administrative Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 8.04 shall continue in effect for the benefit of such

Alenco - Amended and Restated Credit Agreement

retiring or removed Administrative 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 or removed Administrative Agent was acting as Administrative Agent.

SECTION 7.07. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent 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 Article shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the Commitments as well as activities as Administrative Agent. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and non appealable judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

SECTION 7.08. Non-Reliance on Administrative Agent and Other Lenders. Each Lender Party acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender Party or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender Party also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender Party or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

SECTION 7.09. No Other Duties, etc. Anything herein to the contrary notwithstanding, none of the Lead Arrangers, Syndication Agents or Documentation Agents listed on the cover page hereof shall have any powers, duties or responsibilities under this Agreement or any of the other Loan Documents, except in its capacity, as applicable, as the Administrative Agent or a Lender Party hereunder.

In the

Alenco - Amended and Restated Credit Agreement

The Borrower also agrees not to assert any claim against any Agent, any Lead Arranger, any Lender Party, any of their respective Affiliates, or any of their respective directors, officers, employees, attorneys and agents, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to any of the Documents, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Advances.

The amount payable to the Administrative Agent hereunder shall be set forth in a certificate delivered by the applicable Lender to the Administrative Agent and the Borrower (which certificate shall contain reasonable details concerning the calculation of the amount payable) and shall be prima facie evidence thereof, in the absence of manifest error.

(d) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Sections 2.12 and 2.15 and in this 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder.

(e) The Lenders severally agree to indemnify each Issuing Bank (in its capacity as such and to the extent not reimbursed by the Borrower), ratably according to the respective amounts of their Revolving Credit Commitments, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against such Issuing Bank, solely in its capacity as an Issuing Bank, in any way relating to or arising out of the Loan Documents or any action taken or omitted by such Issuing Bank under the Loan Documents; provided, however, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Issuing Bank’s gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse such Issuing Bank promptly upon demand for its ratable share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Borrower to such Issuing Bank under Section 8.04, to the extent that such Issuing Bank is not promptly reimbursed for such costs or expenses by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any amounts indemnifiable hereunder, this Section 8.04(e) applies whether such investigation, litigation or proceeding is brought by the Administrative Agent, any Lender or Issuing Bank or any third party.

SECTION 8.05. Right of Set-off. (a) Upon (i) the occurrence and during the continuance of any Event of Default and (ii) the making of the request or the granting of the consent specified by Section 6.01 by the Required Lenders to authorize the Administrative Agent to declare the Advances due and payable pursuant to the provisions of Section 6.01, each Lender Party and each of its respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or such Affiliate to or for the credit or the account of the Borrower against any and all of the obligations of the Borrower now or hereafter existing under this Agreement, whether or not such Lender Party shall have made any demand under this Agreement and although such obligations may be unmatured. Each Lender Party agrees promptly to notify the Borrower after any such set-off and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender Party and its respective Affiliates under this Section 8.05 are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Lender Party and its respective Affiliates may have.

(b) To the extent permitted by applicable law, at any time a Lender is a Defaulting Lender pursuant to clauses (i) or (ii) of the definition thereof, or while a Lender Insolvency Event exists with respect to such Lender or its Lender Parent, the Borrower is hereby authorized without prior notice to such Defaulting Lender or to any other person, such notice being expressly waived by such Defaulting Lender, to set-off and apply any and all deposits (general and special but excluding security deposits) held by such Defaulting Lender (or any Subsidiary of such Defaulting Lender) to or for the credit of or the account of the Borrower against and on account of the Borrowings and any accrued interest owing by the Borrower to such Defaulting Lender under this Agreement, regardless of whether the obligations in respect of such deposits or Borrowings are contingent or unmatured. The Borrower shall provide the Administrative Agent and the Defaulting Lender with prompt notice of the exercise of any of its rights under this Section; provided that

(i)

any Centralized Banking Arrangements shall take priority over the Borrower’s rights under this Section;

(ii)

prior to receipt of such notice by the Administrative Agent, the Administrative Agent shall not be obligated to reflect such set-off in the allocation of its payments to Lenders under Section 2.14;

(iii)

after receipt of such notice by the Administrative Agent, such Defaulting Lender irrevocably authorizes the Administrative Agent to rely on such notice and to allocate payments from the Borrower to the Lenders in a manner which gives effect to such set-off (notwithstanding any provisions in Section 2.14 to the contrary); and

the Borrower agrees to indemnify the Administrative Agent and its Affiliates, directors, officers, agents and employees from any claims made against any of them by a Defaulting Lender in connection with this Section 8.05(b), all in accordance with Section 11.2 (and for such purposes a claim from a Defaulting Lender shall be deemed to be a third party claim).

SECTION 8.06. Binding Effect. This Agreement shall become effective (other than Section 2.01, which shall only become effective upon satisfaction of the conditions precedent set forth in Section 3.01) when it shall have been executed by the Borrower, the Administrative Agent, the

Alenco - Amended and Restated Credit Agreement

Syndication Agents, the Documentation Agents and each Lead Arranger, and when the Administrative Agent shall have been notified by each Initial Lender, Initial Issuing Bank and the Swing Line Bank that such Initial Lender, Initial Issuing Bank and Swing Line Bank has executed it and thereafter shall be binding upon and inure to the benefit of the Borrower, the Administrative Agent, the Syndication Agents, the Documentation Agents, the Lead Arrangers and each Lender Party and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of all Lenders (and any other attempted assignment or transfer by the Borrower shall be null and void).

No Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Advances at the time owing to it); provided that (in each case with respect to any Facility) any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and/or the Advances at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Advances outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Advances of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $10,000,000 or an integral multiple of $1,000,000 in excess thereof unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

Alenco - Amended and Restated Credit Agreement

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of the Revolving Credit Commitments if such assignment is to a Person that is not a Lender with a Commitment in respect of such Facility, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

(C) the consent of each Issuing Bank and Swing Line Bank (such consent not to be unreasonably withheld or delayed) shall be required for any assignment in respect of the Revolving Credit Commitments.

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Assumption, together with a processing and recordation fee of $3,500; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) the Borrower or any of the Borrower’s Affiliates or Subsidiaries or (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B).

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

(vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Advances previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, each Issuing Bank, each Swing Line Bank and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Advances and participations in Letters of Credit and Swing Line Advances in

Alenco - Amended and Restated Credit Agreement

accordance with its Pro Rata Share. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.12, 2.15 and 8.04 and subject to the obligations of Section 7.05 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in the United States a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Advances owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower, the Administrative Agent, any Issuing Bank or any Swing Line Bank, sell participations to any Person (other than a natural Person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Advances owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) the Borrower, the Administrative Agent and Lender Parties shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 8.05 with respect to any payments made by such Lender to its Participant(s). Each Lender shall, on behalf of the Borrower, maintain at one of its offices a register for the recordation of the names and addresses of its Participants, and the amount and terms of its participation; provided that no Lender shall be required to disclose or share the information contained in such register with the Borrower or any other person, except as required by Applicable Law.

Alenco - Amended and Restated Credit Agreement

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in clause (y) of the first proviso in Section 8.01 that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.12 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant agrees to be subject to the provisions of Section 2.17 as if it were an assignee under paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender; provided that such Participant agrees to be subject to Section 2.15 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 2.12 or 2.15 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that is organized under the laws of a jurisdiction outside of the United States shall not be entitled to the benefits of Section 2.15 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.15(e) as though it were a Lender.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or other central banking authority; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(h) Each Issuing Bank may assign to an Eligible Assignee its rights and obligations or any portion of the undrawn Letter of Credit Commitment at any time; provided, however, that (i) the amount of the Letter of Credit Commitment of the assigning Issuing Bank being assigned pursuant to each such assignment (determined as of the date of the Assignment and Assumption with respect to such assignment) shall in no event be less than $1,000,000 or an integral multiple of $1,000,000 in excess thereof, and (ii) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, an Assignment and Assumption, together with a processing and recordation fee of $3,500.

SECTION 8.08. Confidentiality; Patriot Act. Each of the Administrative Agent, the Syndication Agents, the Documentation Agents, the Lead Arrangers and the Lender Parties agree to maintain the confidentiality of the Confidential Information, except that Confidential Information may be disclosed (a) to its Affiliates and to its Related Parties (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Confidential Information and instructed to keep such Confidential Information confidential); (b) to the extent required or requested by any regulatory authority purporting to have jurisdiction over such Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners, with respect to which such Person shall seek the confidential treatment of such Confidential Information); (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; (d) to any other party hereto; (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or

Alenco - Amended and Restated Credit Agreement

any other Loan Document or the enforcement of rights hereunder or thereunder; (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement, or (ii) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments hereunder; (g) on a confidential basis, to (i) with the consent of the Borrower, any rating agency in connection with rating the Borrower or its Subsidiaries or the indebtedness under this Agreement or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the indebtedness under this Agreement; or (h) otherwise with the consent of the Borrower.

Each Lender that is subject to the Patriot Act and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act.

SECTION 8.09. No Liability of the Issuing Banks. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither any Issuing Bank nor any of its Affiliates, nor any of their officers, directors, employees, agents or advisors shall be liable or responsible for: (a) the use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by such Issuing Bank against presentation of documents that do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit, except that the Borrower shall have a claim against such Issuing Bank, and such Issuing Bank shall be liable to the Borrower, to the extent of any direct, but not consequential, damages suffered by the Borrower that the Borrower proves were caused by (i) such Issuing Bank’s willful misconduct or gross negligence in determining whether documents presented under any Letter of Credit comply with the terms of such Letter of Credit or (ii) such Issuing Bank’s willful failure to make lawful payment under a Letter of Credit after the presentation to it of a draft and certificates strictly complying with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, such Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

SECTION 8.10. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

SECTION 8.11. Extensions of Termination Date (a) The Borrower may, at any time, but in any event not more than once in any calendar year, by delivering to the Administrative Agent a written extension request, request those Lenders which have not become Declining Lenders pursuant to this Section 8.11 (except to the extent Section 8.11(h) applies) (in this Section 8.11, the “Requested Lenders”) to issue a Notice of Extension to extend the then current Termination Date with respect to the Commitments of such Requested Lenders to a date specified therein (each, an “Extended Termination Date”), which Extended Termination Date shall be not later than five (5) years from the date (in this

Alenco - Amended and Restated Credit Agreement

Section 8.11, the “Extension Date”) which is 90 days after the date of such extension request. For the avoidance of doubt, at the time of the first request, if any, made by the Borrower, all Lenders shall be Requested Lenders.

(b) Upon receipt from the Borrower of such written extension request, the Administrative Agent shall forthwith deliver to each Requested Lender a copy of such request, and each Requested Lender shall, within 30 days after the date the Administrative Agent receives such request from the Borrower, advise the Administrative Agent in writing as to whether such Requested Lender will agree to extend the then current Termination Date in respect of its Commitment by delivering to the Administrative Agent a notice in substantially the form of Exhibit F hereto (each such notice being an “Extension Notice”); provided that, if any such Requested Lender shall fail to so advise the Administrative Agent within such 30 day period, then such Requested Lender shall be deemed to have denied such extension request. The determination of each Requested Lender as to whether or not to extend the Termination Date shall be made by each such Requested Lender in its sole discretion.

(i) if (A) all Requested Lenders are in agreement with delivering a notice granting or not granting such extension request (the “Borrower Extension Notice”); or (B) less than all Requested Lenders are in agreement with delivering the Borrower Extension Notice, but, subject to Section 8.11(h)(ii), Requested Lenders having Commitments which, in aggregate, represent 66²⁄₃% or more of all outstanding Commitments of all Requested Lenders are in agreement with delivering the Borrower Extension Notice; (each Requested Lender being in agreement with delivering the Borrower Extension Notice being an “Extending Lender” for the purposes of this Section 8.11), deliver to the Borrower (with a copy to each Extending Lender) the Borrower Extension Notice on behalf of all Extending Lenders, executed by the Administrative Agent and, in the circumstance where not all Requested Lenders are Extending Lenders, advise the Borrower of (I) which Requested Lenders are not in agreement with extending the Termination Date (in this Section 8.11, each a “Declining Lender”); and (II) the amount of each Declining Lender’s Commitments and Advances as at such date; or

(ii) if neither of the conditions in Sections 8.11(c)(i)(A) or (B) shall have been met, notify the Borrower that the extension request has not been approved by Requested Lenders which, subject to Section 8.11(h)(ii), have Commitments which, in aggregate, represent at least 66²⁄₃% of all outstanding Commitments of all Requested Lenders (including therein the identity of the Requested Lenders which are not in agreement with extending the Termination Date and the amount of each such Requested Lender’s Commitments and Advances at such date) and has therefore been denied.

The failure of the Administrative Agent within the aforementioned five day period to deliver the Borrower Extension Notice, as provided in Section 8.11(c)(i) above, shall be deemed to be a notification by the Administrative Agent to the Borrower that the Requested Lenders have denied the extension request, and, in such circumstances, the Termination Date shall not be extended for any of the Requested Lenders.

Alenco - Amended and Restated Credit Agreement

(d) Upon delivery by the Administrative Agent to the Borrower of Borrower Extension Notice pursuant to Section 8.11(c)(i), the Termination Date for all Extending Lenders shall be extended to the Extended Termination Date specified in the relevant extension request.

(e) If in any instance the Borrower Extension Notice has been delivered in circumstances in which not all of the Requested Lenders are Extending Lenders, then, on or prior to the relevant Extension Date:

(i) the Borrower may require any Declining Lender in respect of the relevant extension request to (and such Declining Lender shall thereupon become obligated to) assign all or part of its rights, benefits and interests under the Loan Documents (for purposes of this Section 8.11, the “Assigned Interests”) to:

(A) any Extending Lenders which have agreed to increase their Commitments and purchase the Assigned Interests; and

(B) to the extent the Assigned Interests are not assigned to Extending Lenders in accordance with paragraph (A) above, any financial or other institutions selected by the Borrower and acceptable to the Administrative Agent and the Issuing Banks, acting reasonably.

The Borrower shall provide the Administrative Agent with written notice of its desire to proceed under this Section 8.11(e)(i) (which notice the Administrative Agent shall promptly provide to each Extending Lender), and the Extending Lenders shall be entitled to purchase such of the Assigned Interests as they may request (pro rata, in proportion to the Commitments of those Extending Lenders wishing to purchase Assigned Interests, or otherwise as such Extending Lenders may agree) by written notice to the Administrative Agent and the Borrower within 10 days after receipt of such notice, before any Assigned Interests may be assigned to third party financial or other institutions. Such assignments, in any event, shall be effective upon:

(D) payment to the relevant Declining Lender (in immediately available funds) by the relevant assignee of an amount equal to the aggregate principal amount of all Advances (and accrued and unpaid interest thereon to the effective date of such assignment and all fees and other amounts) owed to that Declining Lender under this Agreement together with all other amounts payable hereunder by the Borrower to such Declining Lender in regard to the Assigned Interests;

(E) payment by the relevant assignee to the Administrative Agent (for the Administrative Agent’s own account) of the transfer fee contemplated in Section 8.07;

(F) provision satisfactory to such Declining Lender (acting reasonably) being made for the indemnification or release of such Declining Lender from its obligations relating to any Letters of Credit or Swing Line Borrowings which form part of the Assigned Interests.

Alenco - Amended and Restated Credit Agreement

Upon such assignment and transfer becoming effective, the Declining Lender shall have no further right, interest, benefit or obligation hereunder to the extent of the Assigned Interests assigned by that Lender but shall continue to be entitled to the benefits of Sections 2.12, 2.15 and 8.04 and subject to the obligations of Section 7.05 with respect to facts and circumstances occurring prior to the effective date of such assignment, and each assignee thereof shall succeed to the position of such Lender to the extent of the portion of the Assigned Interests acquired by such assignee as if the assignee was an original Lender hereunder in regard thereto in the place and stead of such Declining Lender; and

(ii) to the extent that the Borrower has not caused any Declining Lenders in respect of such extension request to assign their respective rights and interests to one or more Extending Lenders and/or other financial or other institutions as provided in paragraph (i) above, the Borrower may, at its option, notwithstanding any other provisions hereof, but only if no Default then exists, by further notice to the Administrative Agent, repay to such Declining Lenders all aggregate principal amount of all Advances owed to such Declining Lenders, together with accrued and unpaid interest thereon and all other amounts owing hereunder to such Declining Lenders, without making corresponding repayment to any other Lenders, and make provision satisfactory to each relevant Declining Lender (acting reasonably) for (A) payment of all costs, losses, premiums or expenses incurred by such Declining Lender by reason of a liquidation or re-deployment of deposits or other funds in respect of all outstanding LIBO Rate Advances owed to such Declining Lender and (B) indemnification or release of such Declining Lender from its obligations relating to all outstanding Letters of Credit or Swing Line Borrowings. Upon such payments and provisions being made, each such Declining Lender shall cease to be a Lender and its Commitment shall be cancelled and the aggregate Commitment amount shall be reduced accordingly.

(f) If the Commitment of a Declining Lender is not assigned in accordance with Section 8.11(e)(i) or repaid in accordance with Section 8.11(e)(ii), then such Declining Lender shall continue to be obliged to make its Lender’s proportion of Borrowings available to the Borrower prior to the Termination Date applicable to its Commitment and on such date:

(i) the Commitment of such Declining Lender shall be automatically terminated and any Advances then owing to such Declining Lender shall be repaid in full together with accrued and unpaid interest thereon and all other amounts owing hereunder to such Declining Lender; and

(ii) the aggregate Commitment amount shall be deemed to be reduced by the amount of such terminated Commitment;

provided that, notwithstanding Section 8.11(e) or any other provision herein, at any time prior to such Termination Date, the Borrower may require any Declining Lender to assign all or (subject to Section 8.07) a portion of its rights, benefits and interests under this Agreement in the same manner and subject to the same procedures as are contemplated in Section 8.11(e)(i) above and, upon such assignment becoming effective, each assignee shall be deemed to be an Extending Lender and the Termination Date applicable to the Assigned Interests shall be extended to the Termination Date applicable to the Commitments of the Extending Lenders; and provided, further, that where the

Alenco - Amended and Restated Credit Agreement

proposed Assigned Interests are less than the aggregate Commitments of all of the Declining Lenders, the Borrower shall ensure that the Commitments of all (but not less than all) of the Declining Lenders are assigned or cancelled either (A) by requiring some or all of the Declining Lenders to (and such Declining Lender shall thereupon become obligated to) assign to the proposed assignee or assignees the same proportion of their respective Commitments as their respective Commitments bear to the aggregate Commitments of all Declining Lenders or (B) if no Default then exists, by repaying to some or all of the Declining Lenders all principal amount of Advances, accrued and unpaid interest and other amounts owing hereunder to the Declining Lenders in the same manner as is contemplated in Section 8.11(e)(ii) above.

(g) This Section 8.11 shall apply from time to time to facilitate successive extensions and requests for extensions of the Termination Date. The Borrower shall not be entitled to request any action or give any notice under this Section 8.11 or receive any extension of the Termination Date in respect of any Commitment so long as there exists a Default or an Event of Default which has not been waived by the Lenders.

(h) The Borrower may, at its option and from time to time (but only pursuant to the delivery of an executed Request for Extension pursuant to Section 8.11(a)), request any Declining Lender to extend the then current Termination Date with respect to the Commitments of such Declining Lender to the proposed Termination Date requested in such extension request. In these circumstances:

(i) the Request for Extension shall expressly refer to such Declining Lender and shall be provided by the Administrative Agent to such Declining Lender;

(ii) such Declining Lender shall be included as one of the Requested Lenders for all purposes of Section 8.11 (except for the purposes of making the percentage calculation contemplated in Sections 8.11(c)(i)(B) or 8.11(c)(ii));

(iii) upon the agreement of such Declining Lender to extend the Termination Date and the delivery of the applicable Borrower Extension Notice from the Administrative Agent to the Borrower, such Declining Lender shall become an Extending Lender and shall cease to be a Declining Lender; and

(iv) in the event such Declining Lender does not, or is deemed to not, agree to extend the Termination Date, Sections 8.11(e) and 8.11(f) shall continue to apply to such Declining Lender as they applied prior to the giving of such Request for Extension.

SECTION 8.12. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by telecopier shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 8.13. Jurisdiction, Etc. (a) Each of the parties hereto unconditionally agrees that it will not commence any action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Borrower, the Guarantor, the Administrative Agent, any Lender Party or any Related Party of the foregoing in any way relating to this Agreement or any other Loan Document or the transactions relating hereto or thereto, in any forum

Each of the parties hereto agrees that a final judgment in any such action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

EACH OF THE BORROWER, THE ADMINISTRATIVE AGENT, THE SYNDICATION AGENTS, THE DOCUMENTATION AGENTS, THE LEAD ARRANGERS, THE LENDERS AND THE ISSUING BANKS HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF THE ADMINISTRATIVE AGENT OR ANY LENDER OR ISSUING BANK IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT THEREOF.

FORM OF OPINION OF

INTERNAL COUNSEL FOR, OR

ACTING ON BEHALF OF, THE

BORROWER AND THE GUARANTOR

[ , 20 ]

To Citibank, N.A.

as Administrative Agent and each

of the Lender Parties

Party to the Credit Agreement

referred to below

Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section [3.01(f)(vii)] [Section 2.19(d)(vi)] of the Second Amended and Restated Credit Agreement dated as of October 20, 2011 (the “Credit Agreement”), among Alenco Inc. (the “Borrower”), the Lenders party thereto, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBS Securities Inc., Citigroup Global Markets Inc., Barclays Capital, the investment bank division of Barclays Bank PLC, and J.P. Morgan Securities LLC, as Lead Arrangers, Citibank, N.A., as Swing Line Bank and Administrative Agent and Bank of America, N.A. and The Royal Bank of Scotland N.V., (Canada) Branch, as Syndication Agents.

I, David F.C. Sheridan, am employed by Encana Corporation (the “Guarantor”) in the position of Associate General Counsel and have acted as in-house counsel on behalf of the Borrower and the Guarantor from time to time. I have acted in connection with the preparation, execution and delivery of the Credit Agreement by the Borrower and the Second Amended and Restated Guaranty dated as of October 20, 2011, by the Guarantor in favor of the Agent and the Lenders referred to above (the “Guaranty”). Terms defined in the Credit Agreement or the Guaranty are used herein as respectively therein defined.

In that connection, I have examined:

(a)

the Credit Agreement;

(b)

the Guaranty;

(c)

the documents furnished to you by the Guarantor at the closing, pursuant to [Section 3.01] [Section 2.19] of the Credit Agreement; and

(d)

the constating documents of the Guarantor and all amendments thereto (the “Guarantor’s Charter Documents”).

The items numbered (a) through (d), above, are hereinafter sometimes collectively referred to as the “Documents”.

I have made such investigations and have examined such public instruments, corporate records and other documents and certificates as I have considered relevant and necessary for the purposes of this opinion.

Based upon and subject to the foregoing and to the qualifications set forth below, and without personal obligation or liability, I am of the opinion that:

1.	Encana Corporation (the “Guarantor”) is validly subsisting as a corporation under the Canada Business Corporations Act.

2.	The Guarantor has all necessary corporate power and authority to execute, deliver and perform its obligations under the Guaranty. The execution, delivery and performance by the Guarantor of the Guaranty have been duly authorized by all necessary corporate action on the part of the Guarantor.

3.	The Guaranty has been duly executed and delivered by the Guarantor.

To the best of my knowledge, there are no pending or overtly threatened actions or proceedings against the Guarantor or its Subsidiaries before any court, governmental agency or arbitrator that purport to affect the legality, validity, binding effect or enforceability of the Documents or the consummation of the transactions contemplated thereby or that are reasonably likely to be determined adversely and, if determined adversely, would have a materially adverse effect upon the business, operations, assets or the financial condition of the Guarantor and its Subsidiaries (including the Borrower) taken as a whole.

To the best of my knowledge, there are no pending or overtly threatened actions or proceedings against the Borrower or its Subsidiaries before any court, governmental agency or arbitrator that purport to affect the legality, validity, binding effect or enforceability of the Documents or the consummation of the transactions contemplated thereby or that are reasonably likely to be determined adversely and, if determined adversely, would have a materially adverse effect upon the business, operations, assets or the financial condition of the Borrower and its Subsidiaries taken as a whole.

The execution, delivery and performance by the Guarantor of the Guaranty, and the consummation of the transactions contemplated thereby, do not (a) violate the Guarantor’s Charter Documents, (b) violate the laws of the Province of Alberta and the federal laws of Canada that, in each case, in my experience, are applicable to credit transactions of the type contemplated by the Guaranty and are in effect on the date hereof (“Covered Laws”) or (c) violate any contractual or legal restriction contained in any document to which the Guarantor is a party.

Except for any filings, authorizations or approvals as are specifically provided for in the Documents, no authorizations, approvals or other action by, and no notice or filings with, any governmental or regulatory authority or agency are necessary under any Covered Law by which the Guarantor is bound for the execution, delivery or performance by the Guarantor of the Guaranty.

Alenco – Exhibits to Second Amended and Restated Credit Agreement

To the best of my knowledge, except for any filings, authorizations or approvals as are specifically provided for in the Documents, no authorizations, approvals or other action by, and no notice or filings with, any third party are necessary under any other documentation by which the Guarantor is bound for the execution, delivery or performance by the Guarantor of the Guaranty.

In any proceeding in a court of competent jurisdiction in the Province of Alberta (an “Alberta Court”) for the enforcement of the Guaranty, the Alberta Court would give effect to the choice of New York law as the proper law governing the Guaranty in respect of all issues which, under the Covered Laws, are to be determined in accordance with the chosen law of the contract, provided that

(a)

such choice of law is bona fide (in the sense that it was not made with a view to avoiding the consequences of the laws of any other jurisdiction) and such choice of law is not contrary to public policy, as that term is understood under any Covered Law (“Public Policy”); to my knowledge, there are no reasons under any Covered Law for avoiding the choice of New York law to govern the Guaranty; and

(b)

in any such proceeding, and notwithstanding the parties’ choice of law, the Alberta Court:

(i)

will not take judicial notice of the provisions of New York law but will only apply such provisions if they are pleaded and proven by expert testimony;

(ii)

will not apply any New York law and will apply Covered Laws to matters which would be characterized under Covered Laws as procedural;

(iii)

will apply provisions of Covered Laws that have overriding effect;

(iv)

will not apply any New York law if such application would be characterized under Covered Laws as the direct or indirect enforcement of a foreign revenue, expropriatory, or penal law or if its application would be contrary to Public Policy; and

(v)

will not enforce the performance of any obligation that is illegal under the laws of any jurisdiction in which the obligation is to be performed.

The opinions expressed herein are limited to the Covered Laws. No opinion is expressed upon the laws of any other jurisdiction.

This opinion relates exclusively to the transaction referred to above and is for the sole use and benefit of the Agent and Lender Parties referred to above. Accordingly, it cannot be relied upon by other parties or used in other transactions without my express written consent.

EXHIBIT D-2 FORM OF OPINION

OF SPECIAL NEW YORK COUNSEL FOR

THE BORROWER AND THE GUARANTOR

[ , 20 ]

To the Lenders party to the Credit

Agreement referred to below

and Citibank, N.A.,

as Administrative Agent

Ladies and Gentlemen:

We have acted as special counsel to Alenco Inc., a Delaware corporation (the “Borrower”), and Encana Corporation, a corporation organized under the laws of Canada (the “Parent Guarantor”, and together with the Borrower, the “Principal Parties”), in connection with (a) the Second Amended and Restated Credit Agreement (the “Credit Agreement”), dated as of the date hereof, among the Borrower, the financial institutions listed on the signature pages of the Credit Agreement (the “Lenders”), Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBS Securities Inc., Citigroup Global Markets Inc., Barclays Capital, the investment bank division of Barclays Bank PLC and J.P. Morgan Securities LLC, as lead arrangers, Bank of America, N.A. and The Royal Bank of Scotland N.V., (Canada) Branch, as syndication agents, Barclays Bank and JPMorgan Chase Bank, N.A. as documentation agents, and Citibank N.A., as Swing Line Bank and Administrative Agent, (the “Agent”) and (b) the Second Amended and Restated Guaranty (the “Guaranty”), dated as of the date hereof, executed by the Parent Guarantor in favor of the Agent and the Lender Parties. This opinion is being furnished to you at the request of the Borrower as provided by [Section 3.01(f)(viii)] [Section

Alenco – Exhibits to Second Amended and Restated Credit Agreement

2.19(d)(vii)] of the Credit Agreement. Capitalized terms used and not otherwise defined have the respective meanings given those terms in the Credit Agreement.

In connection with this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of the following documents, each dated as of the date of this letter (collectively, the “Documents”):

10. the Credit Agreement; and

11. the Guaranty.

In addition, we have examined: (i) those corporate records of the Borrower that we have considered appropriate, including copies of the certificate of incorporation and by-laws of the Borrower certified by it as in effect on the date of this letter (collectively, the “Charter Documents”) and copies of resolutions of the board of directors of the Borrower certified by it; and (ii) those other certificates, agreements and documents that we deemed relevant and necessary as a basis for our opinion. We have also relied upon the factual matters contained in the representations and warranties of the Principal Parties made in the Documents and upon certificates of public officials and the Principal Parties.

In our examination of the documents referred to above, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity of all individuals who have executed any of the documents reviewed by us, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as certified, photostatic, reproduced or conformed copies of valid existing agreements or other documents, the authenticity of the latter documents and that the statements regarding matters of fact in the certificates, records, agreements, instruments and documents that we have examined are accurate and complete. We have

Alenco – Exhibits to Second Amended and Restated Credit Agreement

also assumed, without independent investigation, the enforceability of the Documents against each party other than the Principal Parties.

In addition, in the case of the Parent Guarantor, we have assumed, without independent investigation, that (i) the Parent Guarantor is validly existing and in good standing under the laws of its jurisdiction of organization, (ii) the Parent Guarantor has all necessary corporate power and authority to execute, deliver and perform its obligations under each Document to which it is a party, (iii) the execution, delivery and performance of each Document have been duly authorized by all necessary corporate action and do not violate its charter or other organizational documents or the laws of its jurisdiction of organization and (iv) each Document has been duly executed and delivered by it under the laws of its jurisdiction of organization.

Whenever we indicate that our opinion is based upon our knowledge or words of similar import, our opinion is based solely on an officer’s certificate of the Borrower and Parent Guarantor and without any independent verification or investigation.

Based upon the foregoing, and subject to the assumptions, exceptions and qualifications stated below, we are of the opinion that:

1. The Borrower is a Delaware corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware.

2. The Borrower has all necessary corporate power and authority to execute, deliver and perform its obligations under each Document to which it is a party. The execution, delivery and performance by the Borrower of each Document to which it

Alenco – Exhibits to Second Amended and Restated Credit Agreement

is a party have been duly authorized by all necessary corporate action on the part of the Borrower and do not violate its Charter Documents.

3. Each Document has been duly executed and delivered by each Principal Party which is a party to it. Each Document constitutes the legal, valid and binding obligation of each Principal Party which is a party to it, enforceable against that Principal Party in accordance with its terms.

4. The execution and delivery by each Principal Party of each of the Documents to which it is a party and the performance by the Principal Party of its obligations under the Documents do not (i) violate any Covered Law (as defined below) (including Regulations U or X of the Board of Governors of the Federal Reserve System of the United States), (ii) violate any material order, writ, injunction or decree of which we have knowledge of any court or governmental authority or agency binding upon the Principal Party or to which the Principal Party is subject, (iii) breach or result in a default under any agreement listed on Schedule to which the Principal Party is a party or by which the Principal Party is bound, or (iv) result in the creation or imposition of any Lien upon any of the assets of the Principal Party under the terms of any such agreement.

5. Except for any filings, authorizations or approvals as are specifically provided for in the Documents, no authorizations or approvals of, and no filings with, any governmental or regulatory authority or agency are necessary under any Covered Law for the execution, delivery or performance by any Principal Party of the Documents to which it is a party.

Alenco – Exhibits to Second Amended and Restated Credit Agreement

6. None of the Principal Parties is required to be registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

This opinion is subject to the following assumptions, exceptions and qualifications:

(a) The enforceability of the Documents may be: (i) subject to bankruptcy, insolvency, reorganization, fraudulent conveyance or transfer, moratorium or similar laws affecting creditors’ rights generally; and (ii) subject to general principles of equity (regardless of whether enforceability is considered in a proceeding at law or in equity).

(b) We express no opinion as to: (i) the enforceability of any provisions in the Guaranty purporting to preserve and maintain the liability of any party to the Guaranty despite the fact that the guarantied debt is unenforceable due to illegality; (ii) the enforceability of any provisions contained in the Documents that purport to establish (or may be construed to establish) evidentiary standards; and (iii) the enforceability of forum selection clauses in the federal courts.

This opinion is limited to the laws of the State of New York, the General Corporation Law of the State of Delaware and the federal laws of the United States of America that, in each case, in our experience, are normally applicable to credit transactions of the type contemplated by the Credit Agreement (collectively, the “Covered Laws”). This opinion is rendered only with respect to the laws, and the rules, regulations and orders under those laws, that are currently in effect.

Alenco – Exhibits to Second Amended and Restated Credit Agreement

This opinion is furnished by us solely for your benefit in connection with the transactions referred to in the Credit Agreement and may not be circulated to, or relied upon by, any other Person, except that it may be circulated to any prospective Lender in accordance with the Credit Agreement and may be relied upon by any person who, in the future, becomes a Lender.

3. The Borrower, Barclays, CGMI, BNP Paribas, The Bank of Tokyo Mitsubishi UFJ, Ltd. and The Royal Bank of Scotland plc and the initial lenders named therein amended and restated the 2004 Credit Agreement pursuant to the Amended and Restated Credit Agreement dated as of December 14, 2006, as amended by Amendment No. 1 to the Amended and Restated Credit Agreement effective as of July 31, 2009 (as amended and restated and amended, the “Original Credit Agreement”), and in connection therewith, the Guarantor issued the Amended and Restated Guaranty dated as of December 14, 2006 (the “Original Guaranty”), as a condition precedent to the effectiveness of the Original Credit Agreement.

Alenco – Exhibits to Second Amended and Restated Credit Agreement

terms, the “Credit Agreement”; capitalized terms defined therein and not otherwise defined herein are used herein as therein defined).

5. The Guarantor will derive substantial direct and indirect benefits from the transactions contemplated by the Credit Agreement.

6. It is a condition precedent to the making of advances under the Credit Agreement that the Guarantor shall have executed and delivered this Guaranty.

NOW, THEREFORE, in consideration of the premises, in order to induce the Lead Arrangers, the Syndication Agents, the Administrative Agent and the Lender Parties to enter into the Credit Agreement, the Guarantor hereby agrees as follows:

Section 1. Guaranty. The Guarantor hereby unconditionally and irrevocably guarantees as guarantor and not merely as surety, the punctual payment when due, whether at stated maturity, by acceleration or otherwise, of all obligations of the Borrower now or hereafter existing under the Credit Agreement, whether for principal, interest, fees, expenses or otherwise (such obligations being the “Guaranteed Obligations”), and agrees to pay any and all reasonable expenses (including reasonable counsel fees and out-of-pocket expenses) incurred by the Administrative Agent or any other Lender Party in enforcing any rights under this Guaranty. Without limiting the generality of the foregoing, the Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Borrower to the Administrative Agent or any other Lender Party under the Credit Agreement but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Borrower.

Section 2. Guaranty Absolute. The Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of the Credit Agreement, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Administrative Agent or any other Lender Party with respect thereto. The obligations of the Guarantor under this Guaranty are independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against the Guarantor to enforce this Guaranty, irrespective of whether any action is brought against the Borrower or whether the Borrower is joined in any such action or actions. The liability of the Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and the Guarantor hereby irrevocably waives any defenses it may now or hereafter have in any way relating to, any or all of the following:

(a) any lack of validity or enforceability of the Credit Agreement or any agreement or instrument relating thereto;

Alenco – Exhibits to Second Amended and Restated Credit Agreement

limitation, any increase in the Guaranteed Obligations resulting from the extension of additional credit to the Borrower or any of its Subsidiaries or otherwise;

(c) any taking, exchange, release or non-perfection of any collateral, or any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations;

(d) any manner of application of collateral, or proceeds thereof, to all or any of the Guaranteed Obligations, or any manner of sale or other disposition of any collateral for all or any of the Guaranteed Obligations or any other assets of the Borrower or any of its Subsidiaries;

(e) any change, restructuring or termination of the corporate structure or existence of the Borrower or any of its Subsidiaries or any transfer of the Guaranteed Obligations to a successor;

(f) any failure of any Lender Party to disclose to the Borrower or the Guarantor any information relating to the financial condition, operations, properties or prospects of the Guarantor or the Borrower, as the case may be, now or in the future known to any Lender Party (the Guarantor waiving any duty on the part of the Lender Parties to disclose such information); or

(g) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by the Administrative Agent or any other Lender Party that might otherwise constitute a defense available to, or a discharge of, the Borrower, the Guarantor or any other guarantor or surety.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations is rescinded or must otherwise be returned by any Lender Party or any other Person upon the insolvency, bankruptcy or reorganization of the Borrower or otherwise, all as though such payment had not been made.

Section 3. Waivers and Acknowledgments. (a) The Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that the Administrative Agent or any other Lender Party protect, secure, perfect or insure any Lien or any property subject thereto or exhaust any right or take any action against the Borrower or any other Person or any collateral.

(b) The Guarantor hereby waives any right to revoke this Guaranty, and acknowledges that this Guaranty is continuing in nature and applies to all Guaranteed Obligations, whether existing now or in the future.

(c) The Guarantor acknowledges that it will receive substantial direct and indirect benefits from the financing arrangements contemplated by the Credit Agreement and that the waivers set forth in this Section 3 are knowingly made in contemplation of such benefits.

Alenco – Exhibits to Second Amended and Restated Credit Agreement

Section 4. Subrogation. The Guarantor will not exercise any rights that it may now or hereafter acquire against the Borrower or any other insider guarantor that arise from the existence, payment, performance or enforcement of the Guarantor’s obligations under this Guaranty, including, without limitation, any right of subrogation, reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Administrative Agent or any other Lender Party against the Borrower or any other insider guarantor or any collateral, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from the Borrower or any other insider guarantor, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right, unless and until all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall have been paid in full in cash and the Commitments shall have expired or terminated. If any amount shall be paid to the Guarantor in violation of the preceding sentence at any time prior to the later of the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Guaranty and the Termination Date, such amount shall be held in trust for the benefit of the Administrative Agent and the other Lender Parties and shall forthwith be paid to the Administrative Agent to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the terms of the Credit Agreement, or to be held as collateral for any Guaranteed Obligations or other amounts payable under this Guaranty thereafter arising. If (a) the Guarantor shall make payment to the Administrative Agent or any other Lender Party of all or any part of the Guaranteed Obligations, (b) all of the Guaranteed Obligations and all other amounts payable under this Guaranty shall be paid in full in cash and (c) the Termination Date shall have occurred, the Administrative Agent and the other Lender Parties will, at the Guarantor’s request and expense, execute and deliver to the Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to the Guarantor of an interest in the Guaranteed Obligations resulting from such payment by the Guarantor.

Section 5. Payments Free and Clear of Taxes, Etc. (a) Any and all payments made by the Guarantor hereunder shall be made, in accordance with Section 2.14 of the Credit Agreement, free and clear of and without deduction for any and all Taxes. If the Guarantor shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to the Administrative Agent or any other Lender Party, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent or such other Lender Party (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Guarantor shall make such deductions and (iii) the Guarantor shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, the Guarantor agrees to pay any Other Taxes.

Alenco – Exhibits to Second Amended and Restated Credit Agreement

(c) The Guarantor will indemnify the Administrative Agent and each Lender Party for the full amount of Taxes or Other Taxes imposed on or paid by the Administrative Agent or such other Lender Party (as the case may be) and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 30 days from the date the Administrative Agent or such other Lender Party (as the case may be) makes written demand therefor.

(d) Within 30 days after the date of any payment of Taxes by or on behalf of the Guarantor, the Guarantor will furnish to the Administrative Agent, at its address set forth in Section 8.02(a)(ii) of the Credit Agreement, the original receipt of payment thereof or a certified copy of such receipt.

(e) Without prejudice to the survival of any other agreement of the Guarantor hereunder, the agreements and obligations of the Guarantor contained in this Section 5 shall survive the payment in full of the Guaranteed Obligations and all other amounts payable under this Guaranty.

(f) Each Lender Party that is not a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code, on or prior to the date of its execution and delivery of the Credit Agreement in the case of each initial Lender Party and on the date of the Assignment and Assumption pursuant to which it becomes a Lender Party in the case of each other Lender Party, and from time to time thereafter as requested in writing by the Guarantor or upon the obsolescence, expiration or invalidity of any form previously delivered by such Lender Party (but only so long as such Lender Party remains lawfully able to do so), provide the Guarantor with such original forms or statements as such Lender Party is required to provide to the Borrower or Administrative Agent pursuant to Section 2.15 of the Credit Agreement, and the relevant provisions of Section 2.15 of the Credit Agreement shall govern the rights and obligations of such Lender Party with respect thereto.

(g) In the event that an additional payment is made under this Section 5 for the account of any Lender Party and such Lender Party, in its sole discretion, determines that it has finally and irrevocably received or been granted a credit against or release or remission for, or repayment of, any tax paid or payable by it in respect of or calculated with reference to the deduction or withholding giving rise to such additional payment, such Lender Party shall, to the extent that it determines that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Guarantor such amount as such Lender Party shall, in its sole discretion, have determined to be attributable to such deduction or withholding and which will leave such Lender Party (after such payment) in no worse position than it would have been in if the Guarantor had not been required to make such deduction or withholding; provided that the Guarantor, upon the request of such Lender Party, agrees to pay the amount paid over to the Guarantor (plus penalties, interest and other reasonable charges) to such Lender Party in the event such Lender Party is required to repay such credit, relief, remission or repayment to the applicable taxation authority. Nothing herein contained shall interfere

Alenco – Exhibits to Second Amended and Restated Credit Agreement

with the right of a Lender Party to arrange its tax affairs in whatever manner it thinks fit nor oblige any Lender Party to claim any tax credit or to disclose any information relating to its tax affairs or any computations in respect thereof or require any Lender Party to do anything that would prejudice its ability to benefit from any other credits, reliefs, remissions or repayments to which it may be entitled.

(h) Upon the request of the Borrower or the Guarantor or upon the obsolescence, expiration or invalidity of any form previously delivered by such Lender Party, any Lender Party that is a “United States person” within the meaning of Section 7701(a)(30) of the Internal Revenue Code shall deliver to the Guarantor two original Internal Revenue Service form W-9 or any successor or other form prescribed by the Internal Revenue Service. If any Lender Party fails to deliver Internal Revenue Service form W-9 or any subsequent versions thereof or successors thereto as required herein, then the Guarantor may withhold from any payment to such Lender Party the applicable backup withholding tax imposed by the Internal Revenue Code and remit such amount to the applicable taxation authority if required by law, without reduction, and such Lender Party shall not be entitled to any additional amounts under this Section 5 with respect to Taxes imposed by the United States by reason of such failure.

Section 6. Representations and Warranties. The Guarantor hereby represents and warrants as follows:

(a) The Guarantor is a corporation duly amalgamated and validly existing under the laws of Canada.

(b) The execution, delivery and performance by the Guarantor of this Guaranty, and the consummation of the transactions contemplated hereby, are within the Guarantor’s corporate powers, have been duly authorized by all necessary corporate action, and do not contravene (i) the Guarantor’s charter or by-laws or (ii) law or any contractual restriction binding on or affecting the Guarantor.

(d) This Guaranty has been duly executed and delivered by the Guarantor. This Guaranty is the legal, valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, except to the extent that such enforceability may be limited by any applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights generally from time to time in effect and may be subject to the discretion of courts with respect to the granting of equitable remedies and their power to stay proceedings for the execution of judgments. The enforceability of the obligations of the Guarantor under this Guaranty is also subject to judicial application of foreign laws or foreign governmental actions affecting creditors’ rights.

Alenco – Exhibits to Second Amended and Restated Credit Agreement

(e) The Consolidated balance sheet of the Guarantor and its Subsidiaries as at December 31, 2010, and the related Consolidated statements of earnings and cash flows of the Guarantor and its Subsidiaries for the fiscal year then ended, accompanied by an opinion of PricewaterhouseCoopers LLP, chartered accountants, copies of which have been furnished to each Lender Party, fairly present the Consolidated financial condition of the Guarantor and its Subsidiaries as at such date and the Consolidated results of the operations of the Guarantor and its Subsidiaries for the period ended on such date, all in accordance with GAAP consistently applied.

(g) The operations and properties of the Guarantor and each of its Subsidiaries comply in all material respects with all applicable laws, rules, regulations and orders, and any past non-compliance with any such applicable law, rule, regulation or order has been resolved without any ongoing obligations or costs which could reasonably be expected to have a Material Adverse Effect.

(h) Neither the Guarantor nor any of its Subsidiaries is an Investment Company, as such term is defined in the Investment Company Act of 1940, as amended.

(i) There are no conditions precedent to the effectiveness of this Guaranty that have not been satisfied or waived.

(j) The Guarantor has, independently and without reliance upon the Administrative Agent or any other Lender Party and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Guaranty, and the Guarantor has established adequate means of obtaining from any other Loan Parties on a continuing basis information pertaining to, and is now and on a continuing basis will be completely familiar with, the financial condition, operations, properties and prospects of such other Loan Parties.

(k) The Guarantor has delivered to the Administrative Agent for delivery to each other Lender Party a true and complete copy of the Guarantor Credit Agreement referred to in Section 7(a) below as in effect on the date hereof.

(b) the Guarantor shall retain, directly or indirectly, legal and beneficial ownership of 100% percent of the Voting Shares of the Borrower; and
