In rendering its opinion, Buchanan Ingersoll Professional Corporation may rely (i) as to matters of New York law, on the opinion of Davis Polk & Wardwell referred to in Section 5(e) hereof, and (ii) as to factual matters, on certificates of officers of AWI and its subsidiaries and on certificates of public officials. With respect to matters of Vermont law, Buchanan Ingersoll Professional Corporation may state that in rendering their opinion they have assumed that there are no differences material to such opinion between the laws of the State of Vermont and the laws of the Commonwealth of Pennsylvania. With respect to Section 5(c)(xi) and the immediately preceding paragraph Buchanan Ingersoll Professional Corporation may state that their opinion and belief are based upon their participation in the preparation of the AWI Registration Statement and AWI Prospectus and any amendments or supplements thereto and documents incorporated therein by reference and review and discussion of the contents thereof, but are without independent check or verification, except as specified.

(d) The Underwriters shall have received on the Closing Date an opinion of Deborah K. Owen, General Counsel of AWI, dated the Closing Date, to the effect that: 16 (i) each Material Subsidiary is validly existing as a corporation in good standing under the laws of the jurisdiction of its incorporation, has the corporate power and authority to own its property and to conduct its business as described in the AWI Prospectus; and each of AWI and each of its Material Subsidiaries is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or be in good standing would not have a material adverse effect on AWI and its subsidiaries, taken as a whole; (ii) the statements (A) in the AWI Registration Statement under Item 15,(B) in "Item 3 - Legal Proceedings" of AWI's most recent annual report on Form 10-K incorporated by reference in the AWI Prospectus and (C) in "Item 1 - Legal Proceedings" of Part II of AWI's quarterly reports on Form 10-Q filed since such annual report, in each case insofar as such statements constitute summaries of the legal matters, documents or proceedings referred to therein, and, in each case, as modified by any subsequently filed Current Report on Form 8-K, and in the AWI Prospectus under "Recent Developments," fairly present the information called for with respect to such legal matters, documents and proceedings and fairly summarize the matters referred to therein; (iii) after due inquiry, such counsel does not know of any legal or governmental proceedings pending or threatened to which AWI or any of its Material Subsidiaries is a party or to which any of the properties of AWI or any of its Material Subsidiaries is subject that are required to be described in the AWI Registration Statement or the AWI Prospectus and are not so described, or of any statutes, regulations, contracts or other documents that are required to be described in the AWI Registration Statement or the AWI Prospectus or to be filed or incorporated by reference as exhibits to the AWI Registration Statement that are not described, filed or incorporated as required; (iv) to the best of AWI's knowledge, after due inquiry, AWI and its Subsidiaries (i) are in compliance with any and all applicable Environmental Laws, (ii) have received all material permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in compliance with all terms and conditions 17 of any such permit, license or approval, except where such noncompliance with Environmental Laws, failure to receive required permits, licenses or other approvals or failure to comply with the terms and conditions of such permits, licenses or approvals would not, singly or in the aggregate, have a material adverse effect on AWI and its subsidiaries, taken as a whole; (v) to the best of AWI's knowledge, after due inquiry, there are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) which would, singly or in the aggregate, in AWI's judgment reasonably be expected to have a material adverse effect on AWI and its subsidiaries, taken as a whole, and which have not been previously disclosed in the AWI Registration Statement; (vi) the execution and delivery by AWI of, and the performance by AWI of its obligations under, this Agreement, the Indenture and the PEPS will not contravene any provision of the articles of incorporation or by-laws of AWI or, to the best of such counsel's knowledge, any agreement or other instrument binding upon AWI or any of its subsidiaries that is material to AWI and its subsidiaries, taken as a whole, or, to the best of such counsel's knowledge, any judgment, order or decree of any governmental body, agency or court having jurisdiction over AWI or any subsidiary; (vii) AEI has valid title to the Secondary Shares and AWI will have, upon settlement of the PEPS title to the PEPS Shares and the legal right and power to sell, transfer and deliver the Secondary Shares and the PEPS Shares;

In rendering such opinion, Davis Polk & Wardwell may rely as to all matters of Pennsylvania law upon the opinion of Buchanan Ingersoll referred to in Section 5(c) above. With respect to clause (A) of the antepenultimate paragraph of Section 5(c) and clauses 5(c)(xi)(A) and 5(c)(xi)(B) above, Davis Polk & Wardwell may state that their opinion and belief are based upon their participation in the preparation of the AWI Registration Statement and AWI Prospectus and any amendments or supplements thereto (but not including documents incorporated therein by reference) and review and discussion of the contents thereof (including documents incorporated therein by reference), but are without independent check or verification, except as specified. (f) The Underwriters shall have received on the Closing Date an opinion of Davis Polk & Wardwell, counsel for the Underwriters, dated the Closing Date, covering the matters referred to in Sections 2(c)(vi), 2(c)(xii) (but only as to the statements in each Dal-Tile Prospectus under "Description of Capital Stock," in the Secondary Shares Prospectus under "Underwriting" and in the PEPS Shares Prospectus under "Plan of Distribution") and 2(c)(xii) of the Dal-Tile Indemnification Agreement. With respect to such Section 2(c)(xii) of the Dal-Tile Indemnification Agreement, Davis Polk & Wardwell may state that their opinion and belief are based upon its participation in the preparation of the Dal-Tile Registration Statement and each Dal-Tile Prospectus and any amendments or supplements thereto and review and discussion of the contents thereof, but are without independent check or verification, except as specified. (g) The Underwriters shall have received on each of the date hereof and the Closing Date letters dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Underwriters, from AWI's and Triangle Pacific Corp.'s respective independent public accountants, containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements and certain financial information contained in or incorporated by reference into the AWI Prospectus; PROVIDED that the letter delivered on the Closing Date shall use a "cut-off date" not earlier than the date hereof. (h) The "lock-up" agreements between the you and certain shareholders, officers and directors of each of AWI and AEI relating to sales and certain other dispositions of shares of Common Stock and certain 19 other securities, delivered to you on or before the date hereof, shall be in full force and effect on the Closing Date.

(j) The Shares shall have been listed or approved for listing on the New York Stock Exchange. The several obligations of the Underwriters to purchase Additional Shares or Additional PEPS hereunder are subject to the delivery to you on the Additional Shares Closing Date and Additional PEPS Closing Date, respectively, of such documents as you may reasonably request with respect to the good standing of AWI, AEI and/or Dal-Tile, the due authorization and issuance of the Additional Shares or Additional PEPS, as the case may be, and other matters related to the issuance of the Additional Shares or Additional PEPS, as the case may be. 6. COVENANTS OF AWI. In further consideration of the agreements of the Underwriters herein contained, AWI covenants with each Underwriter as follows: (a) To furnish the PEPS Managers, without charge, 5 signed copies of the AWI Registration Statement (including exhibits thereto) and 5 copies of the AWI Prospectus and for delivery to each other PEPS Underwriter a conformed copy of the AWI Registration Statement (without exhibits thereto) and a copy of the AWI Prospectus in each case not later than 10:00 A.M. on the day following the date hereof and, during the period mentioned in paragraph 6(c) below, as many copies of the AWI Prospectus, any documents incorporated by reference therein and any 20 supplements and amendments thereto or to the AWI Registration Statement as the PEPS Managers may reasonably request. (b) Before amending or supplementing the AWI Registration Statement or the AWI Prospectus with respect to the PEPS, to furnish to the PEPS Managers a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the PEPS Managers reasonably object. (c) If, during such period after the first date of the public offering of the PEPS as, in the opinion of counsel for the Underwriters, the AWI Prospectus is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the AWI Prospectus in order to make the statements therein, in the light of the circumstances when the AWI Prospectus is delivered to a purchaser, not misleading, or if, in the reasonable judgment of AWI or in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the AWI Prospectus to comply with applicable law, AWI will forthwith prepare and file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses the PEPS Managers will furnish to AWI) to which PEPS may have been sold by the PEPS Managers on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the AWI Prospectus so that the statements in the AWI Prospectus as so amended or supplemented will not, in the light of the circumstances when the AWI Prospectus is delivered to a purchaser, be misleading or so that the AWI Prospectus, as amended or supplemented, will comply with applicable law. (d) To cooperate with Underwriter's counsel to qualify the PEPS for offer and sale under the securities or Blue Sky laws of such jurisdictions as the PEPS Managers shall reasonably request and to maintain such qualification for as long as the PEPS Managers shall reasonably request; PROVIDED that in connection therewith AWI shall not be required to qualify as a foreign corporation or file a general consent to service of process in any jurisdiction. (e) To make generally available to AWI's security holders and to the PEPS Managers as soon as practicable an earnings statement covering a twelve month period beginning on the first day of the first full fiscal quarter after the date of this Agreement, which earning statement shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder. If such fiscal quarter is the 21 last fiscal quarter of AWI's fiscal year, such earning statement shall be made available not later than 90 days after the close of the period covered thereby and in all other cases shall be made available not later than 45 days after the close of the period covered thereby. (f) To pay all expenses incident to the performance of its obligations under this Agreement, including: (i) the preparation and filing of the AWI Prospectus and all amendments and supplements thereto; (ii) the preparation, issuance and delivery of the PEPS; (iii) the fees and disbursements of AWI's counsel and accountants and of the Trustee and its counsel; (iv) the qualification of the PEPS and the Shares under state securities or Blue Sky laws in accordance with the provisions of Section 6(d) and Section 3(d) of the Dal-Tile Indemnification Agreement, including filing fees and the fees and disbursements of counsel for the Underwriters in connection therewith and in connection with the preparation of any Blue Sky or Legal Investment Memoranda (the cost of which shall not exceed $3,000); (v) the printing and delivery to the Underwriters in quantities as herein above stated of copies of, and all amendments thereto of any preliminary prospectus and the AWI Prospectus; (vi) the printing and delivery to the Underwriters of copies of any Blue Sky or Legal Investment Memoranda; (vii) any fees charged by rating agencies for the rating of the PEPS; (viii) the filing fees and expenses, if any, incurred with respect to any filing with the National Association of Securities Dealers, Inc. made in connection with the PEPS; (ix) all document production charges and expenses of counsel to the Underwriters incurred in connection with the preparation of this Agreement, the Indemnification Agreement and the Indenture; (x) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon; (xi) any expenses incurred by AWI in connection with a "road show" presentation to potential investors, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of AWI, travel and lodging expenses of the representatives and officers of AWI and any such consultants, and the cost of any aircraft chartered in connection with the road show; and (xii) all other costs and expenses incident to the performance of the obligations of AWI hereunder for which provision is not otherwise made in this Section. The provisions of this Section shall not supersede or otherwise affect any agreement that Dal-Tile and AWI may otherwise have for the allocation of such expenses among themselves. 22 7. INDEMNIFICATION AND CONTRIBUTION. (a) AWI agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred by any Underwriter or any such controlling person in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the AWI Registration Statement or any amendment thereof, any preliminary prospectus of AWI or the AWI Prospectus (as amended or supplemented if AWI shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (A) except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to AWI in writing by such Underwriter through the Managers expressly for use therein, or (B) except that AWI shall not be liable to any Underwriter under this Section 7 to the extent that any such loss, claim, liability or judgment results solely from an untrue statement of a material fact contained in, or the omission of a material fact from, an AWI preliminary prospectus if such untrue statement or omission was completely corrected in the applicable AWI Prospectus Supplement prior to the written confirmation of the sale of the PEPS or Shares, as the case may be, giving rise to such loss, claim, liability or judgment if AWI shall sustain the burden of proving (x) that such Underwriter sold the PEPS or Shares, as the case may be, to the person alleging such loss, claim, damage or liability without sending or giving the applicable AWI Prospectus Supplement or applicable Dal-Tile Prospectus, as the case may be, to such person at or prior to the time of written confirmation of the sale of the PEPS or Shares, as the case may be, giving rise to such loss, claim, liability or judgment and that such delivery to such person was required by law, (y) that AWI had furnished copies of the applicable AWI Prospectus Supplement or applicable Dal-Tile Prospectus, as the case may be, to such Underwriter reasonably prior to the written confirmation of such sale, and (z) such Underwriter would not have been subject to such liability if it had delivered the applicable AWI Prospectus Supplement or applicable Dal-Tile Prospectus, as the case may be, to such person at or prior to the time of written confirmation of such sale. (b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless AWI, its directors, its officers who sign the AWI Registration Statement and each person, if any, who controls AWI within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from AWI to such Underwriter, but only with reference to information relating 23 to such Underwriter furnished to AWI in writing by such Underwriter through the Managers expressly for use in any preliminary prospectus, the AWI Prospectus or any amendments or supplements thereto. (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either paragraph (a) or (b) of this Section 7, such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impeded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by Morgan Stanley & Co. Incorporated, in the case of parties indemnified pursuant to paragraph 7(a) above, and by AWI, in the case of parties indemnified pursuant to paragraph 7(b) above. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have 24 reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. (d) To the extent the indemnification provided for in paragraph 7(a) or 7(b) of this Section is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by AWI on the one hand and the Underwriters on the other hand from the offering of the PEPS or the Shares, as the case may be, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of AWI on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by AWI on the one hand and the Underwriters on the other hand in connection with the offering of the PEPS (or the Shares, as the case may be) shall be deemed to be in the same respective proportions as the net proceeds from the offering of such PEPS (or the Shares, as the case may be) (before deducting expenses) received by AWI and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the AWI Prospectus Supplement (or Dal-Tile Prospectus, as the case may be), bear to the aggregate public offering price of the PEPS (or the Shares, as the case may be). The relative fault of AWI on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by AWI or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the 25 respective principal amounts of PEPS they have purchased hereunder, and not joint. (e) AWI and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by PRO RATA allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph 7(d) of this Section. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the PEPS underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. (f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of AWI contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or AWI, its officers or directors or any person controlling AWI and (iii) acceptance of and payment for any of the PEPS or Shares. 8. TERMINATION. This Agreement shall be subject to termination by notice given by Morgan Stanley & Co. Incorporated to AWI, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange or the National Association of Securities Dealers, Inc., (ii) trading of any securities of AWI or Dal-Tile shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking 26 activities in New York shall have been declared by either Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the judgment of Morgan Stanley & Co. Incorporated, is material and adverse and (b) in the case of any of the events specified in clauses (a)(i) through (iv), such event, singly or together with any other such event, makes it, in the judgment of Morgan Stanley & Co. Incorporated, impracticable to market the PEPS on the terms and in the manner contemplated in the AWI Prospectus or the Secondary Shares on the terms and in the manner contemplated in the Secondary Shares Prospectus. 9. DEFAULTING UNDERWRITERS. If, on the Closing Date or the applicable Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase PEPS (or Shares) that it has or they have agreed to purchase hereunder on such date, and the aggregate number of PEPS (or Shares) which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the PEPS (or Shares) to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm PEPS (or Firm Shares) set forth opposite their respective names in Schedule I (or, in the case of Shares, Schedule II) to this Agreement bears to the aggregate principal amount of PEPS (or Shares) set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as Morgan Stanley & Co. Incorporated may specify, to purchase the PEPS (or Shares) which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of PEPS (or Shares) that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such number of PEPS (or Shares) without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm PEPS (or Firm Shares) and the aggregate principal amount of PEPS (or Shares) with respect to which such default occurs is more than one-tenth of the aggregate principal amount of PEPS (or Shares) to be purchased on such date, and arrangements satisfactory to Morgan Stanley & Co. Incorporated and AWI for the purchase of such PEPS (or Shares) are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or AWI. In any such case either Morgan Stanley & Co. Incorporated or AWI shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the AWI Registration Statement and in the AWI Prospectus (or the Dal-Tile Registration Statement and in the Dal-Tile Prospectus) or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. 27 If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of AWI to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason AWI shall be unable to perform its obligations under this Agreement, AWI will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder. 10.
