     AWI also proposes to issue and sell to the several PEPS Underwriters not

to the extent that you, as the Managers of the offering, shall have determined

          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

     loan, sell, contract to sell, sell any option or contract to purchase,
     purchase any option or contract to sell, grant any option, right or warrant

     is to be settled by delivery of shares of Common Stock or such other

                                          11



          The several obligations of the PEPS Underwriters to purchase the PEPS
     and the several obligations of the Secondary Shares Underwriters to
     purchase the Secondary Shares are each subject to the following further
     conditions:

          (a)  Subsequent to the execution and delivery of this Underwriting
     Agreement and prior to the Closing Date: 

               (i)     there shall not have occurred any downgrading, nor shall
          any notice have been given of any intended or potential downgrading or
          of any review for a possible change that does not indicate the

          organization," as such term is defined for purposes of Rule 436(g)(2)

          Prospectuses, as the case may be (in either case, exclusive of any
          amendments or supplements thereto subsequent to the date of this
          Agreement), that, in the judgment of the PEPS Managers or the
          Secondary Managers, as the case may be, is material and adverse and
          that makes it, in the judgment of the PEPS Managers, impracticable (i)
          with respect only to the several obligations of the PEPS Underwriters,
          to market the PEPS on the terms and in the manner contemplated in the

     certificate, dated the Closing Date and signed by an executive officer of
     AWI, to the effect set forth in clause 5(a)(i) above and to the effect that
     the representations and warranties of AWI contained in this Agreement are

     complied with all of the agreements and satisfied all of the conditions on
     its part to be performed or satisfied hereunder on or before the Closing
     Date.  The officer signing and delivering such certificate may rely upon

               (vi)    the execution and delivery by AWI of, and the performance
          by each of AWI and AEI of its respective obligations under, this

          Agreement) or the articles of incorporation or by-laws of AWI or AEI,
          and no consent, approval, authorization or order of, or qualification
          with, any governmental body or agency is required for the performance
          by AWI or AEI of its obligations under this Agreement, or the
          performance by AWI of its obligations under the Indenture or the PEPS;

          thereto (as defined in Section 8-102 of the UCC);

               (viii)  upon delivery of the PEPS Shares pursuant to the terms of

          to securities accounts (the "Securities Accounts") of the various
          beneficial owners of the PEPS who are direct participants in DTC

          other nominee as may be designated by DTC) lacks notice of any
          "adverse claim" (as defined in Section 8-102 of the Uniform Commercial
          Code as in effect in the State of New York (the "UCC")) to the PEPS
          Shares),  (A) Cede or such other nominee designated by DTC will be a
          "protected purchaser" of the PEPS Shares within the meaning of Section
          8-303 of the UCC, (B) the beneficial owners of the PEPS Shares who are

                                          14



          any "adverse claim" (within the meaning of Section 8-102 of the UCC)
          to the PEPS Shares may be asserted against such beneficial owners with
          respect to such security entitlements (assuming that such beneficial
          owners lack notice of any such adverse claim);

               (ix)    each of AWI and AEI is not, and after giving effect to
          the offering and sale of the PEPS and the Secondary Shares and the
          application of the proceeds thereof as described in the AWI Prospectus
          or the Secondary Shares Prospectus, as the case may be, will not be an
          "investment company" as such term is defined in the Investment Company
          Act of 1940, as amended; 

               (x)     Dal-Tile Corporation is validly existing as a corporation
          in good standing under the laws of the Commonwealth of Pennsylvania
          and has the corporate power and authority to own, lease and operate
          its properties and to conduct its business as described in the
          Dal-Tile Registration Statement and each Dal-Tile Prospectus; and

               (xi)    such counsel is of the opinion that (A)each document, if
          any, filed pursuant to the Exchange Act and incorporated by reference
          in the AWI Prospectus (except for financial statements and related
          schedules and other financial data  included therein as to which such
          counsel need not express any opinion) complied when so filed as to
          form in all material respects with the Exchange Act and the applicable
          rules and regulations of the Commission thereunder and (B) the AWI
          Registration Statement and the AWI Prospectus comply as to form in all
          material respects with the Securities Act and the applicable rules and
          regulations of the Commission thereunder; PROVIDED, HOWEVER, that such
          counsel need not express any opinion or belief as to, with respect to
          clause (B) above, the financial statements, including the notes and
          schedules thereto, and financial or statistical data contained or
          referred to in, or incorporated by reference to in, or incorporated by
          reference in, the AWI Registration Statement or the AWI Prospectus.

          Such counsel shall also state in such opinion that such counsel has no
     reason to believe that (A) each part of the AWI Registration Statement, at
     the time it became effective, and as of the date such opinion is delivered,
     contains any untrue statement of a material fact or omitted or omits to
     state any material fact required to be stated therein or necessary to make
     the statements 


                                          15



     therein not misleading; and (B) the AWI Prospectus, as of the date of the
     AWI Prospectus and as of the date such opinion is delivered, contains any
     untrue statement of a material fact or omits to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,
     however, that such counsel need not express any opinion or belief as to (1)
     with respect to clause (A) above, that part of the AWI Registration
     Statement which constitutes the Statement of Eligibility (Form T-1 under
     the Trust Indenture Act) of the Trustee or (2) with respect to clauses (A)
     and (B) above, the financial statements, including the notes and schedules
     thereto, and any financial or statistical data contained or referred to in,
     or incorporated by reference in, the AWI Registration Statement or the AWI
     Prospectus.

          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. 

          The opinion of Buchanan Ingersoll Professional Corporation described
     in this Section 5(c) shall be rendered to the Underwriters at the request
     of AWI and shall so state therein. 

          (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;

          (e)  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 5(c)(ii),
     5(c)(iii), 5(c)(iv) and 5(c)(v) (but only as to the statements under
     "Description of the PEPS" and "Underwriters") and clause (A) of the
     antepenultimate paragraph of Section 5(c) (but only as of the date such
     opinion is delivered) and clauses, 5(c)(xi)(A) and 5(c)(xi)(B) above, in
     each case subject to the applicable clauses of the provisos contained in 


                                          18



     Section 5(c)(xi) and the antepenultimate paragraph of Section 5(c) .  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.

          (i)  The Dal-Tile Indemnification Agreement shall be in effect as of
     the Closing Date; the representations and warranties of Dal-Tile contained
     in the Dal-Tile Indemnification Agreement shall be true and correct as of
     the date hereof and as of the Closing Date; Dal-Tile shall have complied
     with all of the agreements and satisfied all of the conditions on its part
     to be performed or satisfied under the Dal-Tile Indemnification Agreement
     on or before the Closing Date; the Underwriters shall have received on the
     Closing Date the certificates, opinions and letters described in Sections
     2(c), 2(d), 2(e) and 2(f) of the Dal-Tile Indemnification Agreement; and
     the Underwriters shall have received on the Closing Date a certificate,
     dated the Closing Date and signed by an executive officer of Dal-Tile, to
     the effect that the representations and warranties of Dal-Tile contained in
     the Dal-Tile Indemnification Agreement are true and correct as of the
     Closing Date and that Dal-Tile has complied with all of the agreements and
     satisfied all of the conditions on its part to be performed or satisfied
     thereunder on or before 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
