ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Subsection (a) of Section 145 of the DGCL empowers a corporation to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action, suit or proceeding whether
civil, criminal, administrative or investigative (other than an action by or in
the right of the corporation) by reason of the fact that he is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fee), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believes to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.
 
    Subsection (b) of Section 145 empowers a corporation to indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action or suit by right of the corporation to procure a
judgment in its favor by reason of the fact that such person acted in any of the
capacities set forth above, against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification may be made in respect to any claim
issue or matter as to which such person shall have been adjudged to be liable to
the corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.
 
    Section 145 further provides that to the extent a director or officer of a
corporation has been successful on the merits or otherwise in the defense of any
such action, suit or proceeding referred to in subsections (a) and (b) of
Section 145 or in the defense of any claim, issue or matter therein, he shall be
 
                                      II-1
<PAGE>
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith; that the indemnification provided for
by Section 145 shall not be deemed exclusive of any other rights which the
indemnified party may be entitled; that indemnification provided by Section 145
shall, unless otherwise provided when authorized or ratified, continue as to a
person who has ceased to be a director, officer, employee or agent and shall
inure to the benefit of such person's heirs, executors and administrators; and
empowers the corporation to purchase and maintain insurance on behalf of a
director or officer of the corporation against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liabilities under Section 145.
 
    Section 102(b)(7) of the DGCL provides that a certificate of incorporation
may contain a provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, provided that such provision shall not
eliminate or limit the liability of the director (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any
transaction from which the director derived an improper personal benefit.
 
    Article Ninth of the registrant's Certificate of Incorporation, as amended
and restated, provides that, to the fullest extent permitted by the DGCL, no
director of the registrant shall be personally liable to the registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director.
 
    Article VII of the registrant's Bylaws, as amended, further provides that
the registrant shall indemnify each of its directors and officers against
expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with any third party proceeding
if such person acted in good faith and in a manner such person reasonably
believed to be in, or not opposed to, the best interests of the registrant and,
with respect to any criminal third party proceeding, had no reasonable cause to
believe such conduct was unlawful.
 
    The registrant has entered into indemnification agreements with each of its
directors and executive officers.
 
    The registrant maintains officers' and directors' liability insurance.
 
    Pursuant to the Underwriting Agreement filed as Exhibit 1.1 hereto, the
Underwriters agree to indemnify, under certain conditions, the registrant, its
officers and directors and persons who control the registrant within the meaning
of the Securities Act against certain liabilities.

ITEM 17.  UNDERTAKINGS.
 
    The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act), that is
incorporated by reference in this Registration Statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial BONA
FIDE offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation, as amended, or the Bylaws, as amended, of the registrant, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Securities Act, and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question of whether such indemnification by it is against
public policy as expressed in the Securities Act and will be governed by the
final adjudication of such issue.
 
    The undersigned registrant hereby undertakes that:
 
        For purposes of determining any liability under the Securities Act, the
    information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.
 
        For the purposes of determining any liability under the Securities Act,
    each post-effective amendment that contains a form of prospectus shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.

     Underwriters of even date herewith), and 540,000 Firm Shares (the

     in connection with the offering and sale of such International Shares

     International Underwriters.  The U.S. Underwriters and the International 
     Underwriters are hereinafter collectively referred to as the 
     "UNDERWRITERS."
     
          The Company also proposes to issue and sell to the several U.S. 
     Underwriters, and DCEO proposes to sell to the several U.S.

     referred to as the "SELLERS."

          The Company has filed with the Securities and Exchange Commission

     connection with the offering and sale of the Shares: the U.S. 
     prospectus, to be used in connection with the offering and sale of 
     Shares in the United States and Canada to United States and Canadian 
     Persons, and the international prospectus, to be used in connection with 
     the offering and sale of Shares outside the United States and Canada to 
     persons other than United States and Canadian Persons.  The 
     international prospectus is identical to the U.S. prospectus except for 
     the outside front cover page.  The registration statement as amended at 
     the time it becomes effective, 

                                       2

     statement at the time of effectiveness pursuant to Rule 430A under the 
     Securities Act of 1933, as amended (the "SECURITIES ACT"), is 
     hereinafter referred to as the "REGISTRATION STATEMENT"; the U.S. 
     prospectus and the international prospectus in the respective forms 
     first used to confirm sales of Shares are hereinafter collectively 
     referred to as the "PROSPECTUS."  If the Company has filed an 
     abbreviated registration statement to register additional shares of 
     Common Stock pursuant to Rule 462(b) under the Securities Act (the "RULE 
     462 REGISTRATION STATEMENT"), then any reference herein to the term 
     "REGISTRATION STATEMENT" shall be deemed to include such Rule 462 
     Registration Statement (including, in the case of all references to the 
     Registration and the Prospectus, documents incorporated therein by 
     reference).  The terms "SUPPLEMENT" and "AMENDMENT" or "AMEND" as used 
     in this Agreement shall include all documents subsequently filed by the 
     Company with the Commission pursuant to the Securities Exchange Act of 
     1934, as amended, (the "EXCHANGE ACT")  that are deemed to be 
     incorporated by reference in the Prospectus.

            respects with the Exchange Act and the applicable rules and 
            regulations of the Commission thereunder, (ii) the Registration 
            Statement, when it became effective, did not contain and, as

            fact required to be stated therein or necessary to make the 
            statements therein not misleading, (iii) the Registration 
            Statement and the Prospectus comply and, as amended or 
            supplemented, if applicable, will comply in all material respects 
            with the Securities Act and the applicable rules and regulations 
            of the Commission thereunder and (iv) the Prospectus does not 
            contain and, as amended or supplemented, if applicable, will not

            the conduct of its business or its ownership or leasing of

            the failure to be so qualified or be in good standing would not 
            have a material adverse effect on the Company and the 
            Subsidiaries (as defined below), taken as a whole.

            conduct its business and is duly qualified to transact business 
            and is in good standing in each jurisdiction in which the conduct

            so qualified or be in good standing would not have a material 
            adverse effect on the Company and the Subsidiaries, taken as a 
            whole.  As used herein, "SUBSIDIARY" shall mean DuPont Photomasks

            assets and to conduct its business in the manner described in the

            whole.

               (l)  There are no legal or governmental proceedings pending

               (m)  Each preliminary prospectus filed as part of the 
            registration statement as originally filed or as part of any 
            amendment thereto, or filed pursuant to Rule 424 under the 
            Securities Act, complied when so filed in all material respects 
            with the Securities Act and the applicable rules and regulations 
            of the Commission thereunder.

               (n)  The Company is not and, after giving effect to the 
            offering and sale of the Shares and the application of the 
            proceeds as described in the Prospectus, will not be an 
            "INVESTMENT COMPANY" as such term is defined in the Investment 
            Company Act of 1940, as amended.

               (o)  The Company and the Subsidiaries (i) are in compliance 
            with any and all applicable foreign, federal, state and local 
            laws and regulations relating to the protection of human health 
            and safety, the environment or hazardous or toxic substances or 
            wastes, pollutants or contaminants ("ENVIRONMENTAL LAWS"), (ii) 
            have received all 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 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 

                                       6

<PAGE>

            approvals would not, singly or in the aggregate, have a material 
            adverse effect on the Company and the Subsidiaries, taken as a 
            whole.

               (p)  In the ordinary course of its business, the Company 
            conducts a periodic review of the effect of Environmental Laws on 
            the business, operations and properties of the Company and the 
            Subsidiaries, in the course of which it identifies and evaluates 
            associated costs and liabilities (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).  On the basis of the last such review so completed, the 
            Company has reasonably concluded that such associated costs and 
            liabilities would not, singly or in the aggregate, have a 
            material adverse effect on the Company and the Subsidiaries, 
            taken as a whole, except as described in the Registration 
            Statement or Prospectus.

               (q)  Each of the Company and the Subsidiaries owns or 
            possesses adequate licenses or other rights to use all patents, 
            patent rights, inventions, trade secrets, technology, know-how, 
            trademarks, service marks, trade names and copyrights which are 
            necessary to conduct its businesses as described in the 
            Registration Statement and Prospectus, and the expiration of any 
            patents, patent rights, trade secrets, trademarks, service marks, 
            trade names or copyrights would not have a material adverse 
            effect on the Company and the Subsidiaries, taken as a whole.  
            The Company has not received any notice of, and has no knowledge 
            of, any infringement of or conflict with asserted rights of 
            others with respect to, any patents, patent rights, inventions, 
            trade secrets, technology, know-how, trademarks, service marks, 
            trade names which, singly or in the aggregate, if the subject of 
            an unfavorable decision, ruling or finding, might have a material 
            adverse effect on the Company and the Subsidiaries, taken as a 
            whole.

               (r)  There are no contracts, agreements or understandings 
            between the Company and any person granting such person the right 
            to require the Company to file a registration statement under the 
            Securities Act with respect to any securities of the Company or 
            to require the Company to include such securities with the Shares 
            registered pursuant to the Registration Statement 

                                       7

            other than the rights of DCEO and its assignees as described in the

            Agreement, except such as may be required by the securities or 
            Blue Sky laws of the various states in connection with the offer 
            and sale of the Shares.

               (c)  DCEO has, and on the Closing Date will have, valid title 
            to the Shares to be sold by it and the legal right and power, and

            Agreement will pass title to such Shares free and clear of any 
            security interests, claims, liens, equities and other 
            encumbrances.
     
          3.   AGREEMENTS TO SELL AND PURCHASE.  Each Seller, severally and not

     of Firm Shares to be sold by such Seller as the number of Firm Shares set
     forth in Schedules I and II hereto opposite the name of such Underwriter 
     bears to the total number of Firm Shares.
  
          On the basis of the representations and warranties contained in this 
     Agreement, and subject to its terms and conditions, the Company agrees 
     to issue and sell to the U.S. Underwriters up to 105,000 Additional 
     Shares, DCEO agrees to sell to the U.S. Underwriters up to 300,000 
     Additional Shares and the U.S. Underwriters shall have a one-time right 
     to purchase, severally and not jointly, up to an aggregate of 405,000 
     Additional Shares at the Purchase Price.  If the U.S. Representatives, 
     on behalf of the U.S. Underwriters, elect to exercise such option, the 
     U.S. Representatives shall so notify the Sellers in writing not later 
     than 30 days after the date of this Agreement, which notice shall 
     specify the number of Additional Shares to be purchased by the U.S. 
     Underwriters and the date on which such shares are to be purchased.  
     Such date may be the same as the Closing Date (as defined below) but not 
     earlier than the Closing Date nor later than ten business days after the 
     date of such notice.  Additional Shares may be purchased as provided in 
     Section 5 hereof solely for the purpose of covering over-allotments made 
     in connection with the offering of the Firm Shares.  If any Additional 
     Shares are to be purchased, (i) each Seller agrees, severally and not 
     jointly, to sell to the U.S. Underwriters the Additional Shares pro rata 
     in proportion to the maximum number of Additional Shares such Seller has 
     agreed to sell (subject to such adjustments to eliminate fractional 
     shares as the U.S. Representatives may determine), and (ii) each U.S. 
     Underwriter agrees, severally and not jointly, to purchase from each 
     Seller the number of Additional Shares (subject to such adjustments to 
     eliminate fractional shares as the U.S. Representatives may determine) 
     that bears the same proportion to the total number of Additional Shares 
     to be sold by such Seller as the number of U.S. Firm Shares set forth in 
     Schedule I hereto opposite the name of such U.S. Underwriter bears to 
     the total number of U.S. Firm Shares.

          Each of the Company, DCEO and DuPont hereby agrees that, without the 
     prior written consent of Morgan Stanley & Co. Incorporated on behalf of

     exchangeable for Common Stock or (ii) enter into any swap or other 
     agreement that transfers to another, in whole or in part, any of the 
     economic consequences of ownership of the Common Stock, whether any such 
     transaction described in

     addition, each of DCEO and DuPont agrees that, without the prior written 
     consent of Morgan Stanley & Co. Incorporated on behalf of the 
     Underwriters, it will not, during the period ending 90 days after the

               the rules and regulations of the Commission thereunder, (B) is 
               of the opinion that the Registration Statement and Prospectus

               schedules and other financial and statistical data included

               statistical data as to which such counsel need not express any 
               belief) the Registration Statement and the prospectus included 
               therein at the time the Registration Statement became effective

               state a material fact required to be stated therein or necessary
               to make the statements therein not misleading and (D) has no 
               reason to believe that (except for financial statements and 
               schedules as to which such counsel need not express any 
               belief) the Prospectus 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.
                 
                   (iv) the execution and delivery by the Company of, and the 
               performance by the Company of its obligations under, this 
               Agreement will not contravene any provision of applicable law 
               or the certificate of incorporation or by-laws of the Company 
               or, to the best of such counsel's knowledge, any agreement or

               any governmental body or agency is required for the 
               performance by the Company of its obligations under this

               compliance with all terms and conditions of any such permit,

               terms and conditions of such permits, licenses or approvals 
               would not, singly or in the aggregate, have a material adverse 
               effect on the Company and the Significant Subsidiaries, taken 
               as a whole; and
     
                  (vii) each of the Company and the Significant Subsidiaries

               copyrights which are necessary to conduct its businesses as 
               described in the Registration Statement and Prospectus;  after

               aggregate, if the subject of an unfavorable decision, ruling 
               or finding, might have a material adverse effect on the 
               Company and the Subsidiaries, taken as a whole.
     
          With respect to the opinions set forth in subsection (ii) above, to 
     the extent such opinions address questions of law other than those of the 
     State of Texas, the State of California, or the General Corporation Law of
     the State of Delaware, such counsel may deliver opinions of local counsel 
     as to such matters.

               of, and the performance by DCEO and DuPont of their respective 
               obligations under, this Agreement will not contravene any 
               provision of applicable law, or the certificate of 
               incorporation or by-laws of DCEO or DuPont, or, to the best of 
               such counsel's knowledge, any agreement or other instrument 
               binding upon DCEO or DuPont or, to the best of such counsel's 
               knowledge, any judgment, order or decree of any governmental

               encumbrances, assuming that the Underwriters do not have 
               notice of any adverse claim.
     
              (g)  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

     Prospectus and any amendments or supplements thereto and documents 
     incorporated therein by reference and review and discussion of the contents
     thereof, but is without independent check or verification except as 
     specified.  With respect to clauses (B), (C) and (D) of Section 6(c)(x) 
     above, Davis Polk & Wardwell may state that their opinion and belief are 
     based upon their participation in the preparation of the Registration 
     Statement and Prospectus and any amendments or supplements thereto (other
     than the documents incorporated 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.
     
          The opinion of Brobeck, Phleger & Harrison LLP, John M. Lynn, Esq. and
     Donald P. McAviney described in Sections 6(c), 6(d) and 6(f) above shall be

             (h)  The Underwriters shall have received, on each of the date 
          hereof and the Closing Date, a letter dated the date hereof or the 
          Closing Date, as the case may be, in form and substance 
          satisfactory to the Underwriters, from Price Waterhouse LLP, 
          independent 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 the Registration Statement and 
          the Prospectus; PROVIDED that the letter delivered on the Closing 
          Date shall use a "CUT-OFF DATE" not earlier than the date hereof.
     
             (i)  The "LOCK-UP" agreements, each substantially in the form of 
          Exhibit A hereto, between you and executive officers and directors 
          of the Company relating to sales and certain other dispositions of 
          shares of Common Stock or certain other securities, delivered to 
          you on or before the date hereof, shall be in full force and effect 
          on the Closing Date.

          The several obligations of the U.S. Underwriters to purchase 
     Additional Shares hereunder are subject to the delivery to the U.S. 
     Representatives on the Option Closing Date of such documents as they may
     reasonably request with respect to the good standing of the Company, the
     due authorization and issuance of the Additional Shares and other matters
     related to the issuance of the Additional Shares.

          7. COVENANTS OF THE COMPANY AND DUPONT.  In further consideration of 
     the agreements of the Underwriters herein contained, the Company and, with
     respect to Section 7(f) below, DuPont, covenants with each Underwriter as 
     follows:
     
                (a)  To furnish to you, without charge, a signed copy of the 
           Registration Statement (including exhibits thereto and documents 
           incorporated therein by reference) and for delivery to each other 
           Underwriter a conformed copy of the Registration Statement (without 
           exhibits thereto and including documents incorporated therein by 
           reference) and to furnish to you in New York City, without charge, 
           prior to 5:00 P.M. local time on the business day following the 
           date of this Agreement and during the period mentioned in Section 
           7(c) below, as many copies of the Prospectus and any supplements 
           and amendments thereto or to the Registration Statement as you may 
           reasonably request.

                (b)  Before amending or supplementing the Registration Statement
           or the Prospectus, to furnish to you a copy of each such proposed 
           amendment or supplement and not to file any such proposed amendment 
           or supplement to which you reasonably object in writing, subject 
           however, to compliance with the Securities Act, the Exchange Act, 
           and the rules and regulations thereunder, and to file with the 
           Commission within the applicable period specified in Rule 424(b) 
           under the Securities Act any prospectus required to be filed 
           pursuant to such Rule.
     
                (c)  If, during such period after the first date of the public 
            offering of the Shares as in the opinion of counsel for the 
            Underwriters the 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 Prospectus in order to make the statements 
            therein, in the light of the circumstances when the Prospectus is 
            delivered to a purchaser, not misleading, or if, in the opinion of 
            counsel for the Underwriters, it is necessary to amend or 
            supplement the Prospectus to comply with applicable law, forthwith 
            to prepare, file with the Commission and furnish, at its own 
            expense, to the Underwriters and to the dealers (whose names and 
            addresses you will furnish to the Company) to which Shares may have 
            been sold by you on behalf of the Underwriters and to any other 
            dealers upon request, either amendments or supplements to the 
            Prospectus so that the statements in the Prospectus as so

                                      20
<PAGE>

            amended or supplemented will not, in the light of the circumstances 
            when the Prospectus is delivered to a purchaser, be misleading or 
            so that the Prospectus, as amended or supplemented, will comply 
            with law.
                        
                (d)  To endeavor to qualify the Shares for offer and sale under 
            the securities or Blue Sky laws of such jurisdictions as you shall 
            reasonably request.
                 
                (e)  To make generally available to the Company's security 
            holders and to you as soon as practicable an earning statement 
            covering the twelve-month period ending June 30, 1999 that satisfies
            the provisions of Section 11(a) of the Securities Act and the rules 
            and regulations of the Commission thereunder.
            
                (f)  Whether or not the transactions contemplated in this 
            Agreement are consummated or this Agreement is terminated, to pay 
            or cause to be paid all expenses incident to the performance of its

            disbursements of counsel for the Underwriters in connection with 
            such qualification and in connection with the Blue Sky or Legal 
            Investment memorandum, (iv) all filing fees and reasonable fees and 
            disbursements of counsel to the Underwriters incurred in connection 
            with the review and qualification of the offering of the Shares by

            connection with the offer and sale of the Shares outside the United 
            States, including filing fees and the reasonable fees and

            incident to the performance of the obligations of the Company 
            hereunder for which provision is not otherwise made in this 
            Section.  It is understood, however, that except as provided in 
            this Section, Section 8 entitled "INDEMNITY AND CONTRIBUTION", and 
            the last paragraph of Section 10 below, the Underwriters will pay 
            all of their costs and expenses, including fees and disbursements 
            of their counsel, stock transfer taxes payable on resale of any of 
            the Shares by them, and any advertising expenses connected with any 
            offers they may make.
     
          The provisions of this Section shall not supercede or otherwise affect
     any agreement that the Sellers may otherwise have for the allocation of 
     such expenses among themselves.
     
         8.   INDEMNITY AND CONTRIBUTION.  (a)  The Company and DuPont, jointly 
     and severally, agree 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 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 Registration Statement or 
     any amendment thereof, any preliminary prospectus or the Prospectus (as 
     amended or supplemented if the Company 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 

                                      22
<PAGE>


     to make the statements therein not misleading, 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 the Company in 
     writing by such Underwriter through you expressly for use therein; 
     PROVIDED that the foregoing indemnity agreement with respect to any 
     preliminary prospectus shall not inure to the benefit of any Underwriter 
     from whom the person asserting any such losses, claims, damages or 
     liabilities purchased Shares, or any person controlling such 
     Underwriter, if a copy of the Prospectus (as then amended or 
     supplemented if the Company shall have furnished any amendments or 
     supplements thereto) was not sent or given by or on behalf of such 
     Underwriter to such person, if required by law so to have been 
     delivered, at or prior to the written confirmation of the sale of the 
     Shares to such person, and if the Prospectus (as so amended or 
     supplemented) would have cured the defect giving rise to such losses, 
     claims, damages or liabilities, unless such failure is the result of 
     noncompliance by the Company with Section 7(a) hereof.
     
         (b)  Each Underwriter agrees, severally and not jointly, to indemnify 
     and hold harmless the Company, the directors of the Company, the 
     officers of the Company who sign the Registration Statement, and DuPont, 
     and each person, if any, who controls the Company or DuPont 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 the 
     Company and DuPont to such Underwriter but only with reference to 
     information relating to such Underwriter furnished to the Company in 
     writing by such Underwriter through you expressly for use in the 
     Registration Statement, any preliminary prospectus, the 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 Section 8(a) or 8(b), 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 reasonable 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 impleaded 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 

                                      23
<PAGE>

     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 (i) all 
     Underwriters and all persons, if any, who control any Underwriter within 
     the meaning of either Section 15 of the Securities Act or Section 20 of 
     the Exchange Act and (ii) the Company, its directors, its officers who 
     sign the Registration Statement, DuPont and each person, if any, who 
     controls the Company or DuPont within the meaning of either such Section 
     and that all such fees and expenses shall be reimbursed as they are 
     incurred.  In the case of any such separate firm for the Underwriters 
     and such control persons of the Underwriters, such firm shall be 
     designated in writing by Morgan Stanley & Co. Incorporated.  In the case 
     of any such separate firm for the Company and such directors, officers 
     and control persons of the Company such firm shall be designated in 
     writing by the Company.  In the case of any such separate firm for 
     DuPont, and such directors, officers and control persons of DuPont, such 
     firm shall be designated in writing by DuPont.  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 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 Section 8(a) or 
     8(b) 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 the indemnifying party or 
     parties on the one hand and the indemnified party or 

                                      24
<PAGE>

     parties on the other hand from the offering of the Shares 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 the indemnifying party or parties on the one hand and of the 
     indemnified party or parties 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 the Company and DuPont on the one hand 
     and the Underwriters on the other hand in connection with the offering 
     of the Shares shall be deemed to be in the same respective proportions 
     as the net proceeds from the offering of the Shares (before deducting 
     expenses) received by the Company and DCEO 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 Prospectus, bear to the 
     aggregate Public Offering Price of the Shares.  The relative fault of 
     the Company and DuPont 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 the Company or DuPont 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 8 are several in proportion to the respective number of Shares 
     they have purchased hereunder, and not joint.
     
         (e)  The Company, DuPont and the Underwriters agree that it would not 
     be just or equitable if contribution pursuant to this Section 8 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 Section 8(d).  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 8, no Underwriter shall be required to 
     contribute any amount in excess of the amount by which the total price 
     at which the Shares 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 

                                      25
<PAGE>

     Section 8 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 8 and the representations, warranties and other statements of 
     the Company, DCEO and DuPont 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 the Company, 
     its officers or directors or any person controlling the Company or 
     DuPont, its officers or directors or any person controlling DuPont and 
     (iii) acceptance of and payment for any of the Shares.
     
          9.   TERMINATION.  This Agreement shall be subject to termination by 
     notice given by you to the Company, 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, the National Association of Securities Dealers, Inc., the 
     Chicago Board of Options Exchange, the Chicago Mercantile Exchange or 
     the Chicago Board of Trade, (ii) trading of any securities of the 
     Company shall have been suspended on any exchange or in any 
     over-the-counter market, (iii) a general moratorium on commercial 
     banking 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 your judgment, is material 
     and adverse and (b) in the case of any of the events specified in 
     clauses 9(a)(i) through 9(a)(iv), such event, singly or together with 
     any other such event, makes it, in your judgment, impracticable to 
     market the Shares on the terms and in the manner contemplated in the 
     Prospectus.

          10.  EFFECTIVENESS; DEFAULTING UNDERWRITERS.  This Agreement shall 
     become effective upon the execution and delivery hereof by the parties 
     hereto.
     
          If, on the Closing Date or the Option Closing Date, as the case may 
     be, any one or more of the Underwriters shall fail or refuse to purchase 
     Shares that it has or they have agreed to purchase hereunder on such 
     date, and the aggregate number of 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 Shares to be 
     purchased on such date, the other Underwriters shall be obligated 
     severally in the proportions that the number of Firm Shares set forth 
     opposite their respective names in Schedule I or Schedule II bears to 
     the aggregate number of Firm Shares set forth opposite the names of all 
     such non-defaulting Underwriters, or in such other proportions as you 
     may specify, to purchase the Shares which such defaulting Underwriter or 
     Underwriters agreed but failed or 

                                      26
<PAGE>

     refused to purchase on such date; PROVIDED that in no event shall the 
     number of Shares that any Underwriter has agreed to purchase pursuant to 
     this Agreement be increased pursuant to this Section 10 by an amount in 
     excess of one-ninth of such number of Shares without the written consent 
     of such Underwriter.  If, on the Closing Date, any Underwriter or 
     Underwriters shall fail or refuse to purchase Firm Shares and the 
     aggregate number of Firm Shares with respect to which such default 
     occurs is more than one-tenth of the aggregate number of Firm Shares to 
     be purchased, and arrangements satisfactory to you, the Company and DCEO 
     for the purchase of such Firm Shares are not made within 36 hours after 
     such default, this Agreement shall terminate without liability on the 
     part of any non-defaulting Underwriter, the Company or DCEO. In any such 
     case either you, the Company or DCEO 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 Registration Statement and in 
     the Prospectus or in any other documents or arrangements may be 
     effected.  If, on the Option Closing Date, any U.S. Underwriter or U.S. 
     Underwriters shall fail or refuse to purchase Additional Shares and the 
     aggregate number of Additional Shares with respect to which such default 
     occurs is more than one-tenth of the aggregate number of Additional 
     Shares to be purchased, the non-defaulting U.S. Underwriters shall have 
     the option to (i) terminate their obligation hereunder to purchase 
     Additional Shares or (ii) purchase not less than the number of 
     Additional Shares that such non-defaulting U.S. Underwriters would have 
     been obligated to purchase in the absence of such default.  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.
     
         If this Agreement shall be terminated by the Underwriters, or any of 
     them, because of any failure or refusal on the part of the Company, DCEO 
     or DuPont to comply with the terms or to fulfill any of the conditions 
     of this Agreement, or if for any reason the Company, DCEO or DuPont 
     shall be unable to perform its obligations under this Agreement, the 
     Company, DCEO or DuPont 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.
     
         11.  COUNTERPARTS.  This Agreement may be signed in two or more 
     counterparts, each of which shall be an original, with the same effect 
     as if the signatures thereto and hereto were upon the same instrument.
     
         12.  APPLICABLE LAW.  This Agreement shall be governed by and 
     construed in accordance with the internal laws of the State of New York.

Dear Sirs and Mesdames:

  The undersigned understands that Morgan Stanley & Co. Incorporated ("MORGAN 
STANLEY") and Morgan Stanley & Co. International Limited ("MSIL") propose to 
enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT") with 
DuPont Photomasks, Inc., a Delaware corporation (the "COMPANY"), DuPont 
Chemical and Energy Operations, Inc., a Delaware corporation, and E.I. du 
Pont de Nemours and Company, a Delaware corporation, providing for the public 
offering (the "PUBLIC OFFERING") by the several Underwriters, including 
Morgan Stanley and MSIL (the "UNDERWRITERS") of 2,700,000 shares (the 
"SHARES") of the Common Stock, par value $.01 per share, of the Company (the 
"COMMON STOCK").

<PAGE>

  To induce the Underwriters that may participate in the Public Offering to 
continue their efforts in connection with the Public Offering, the 
undersigned hereby agrees that, without the prior written consent of Morgan 
Stanley on behalf of the Underwriters, it will not, during the period 
commencing on the date hereof and ending 90 days after the date of the final 
prospectus relating to the Public Offering of the Shares (the "PROSPECTUS"), 
(1) offer, pledge, sell, contract to sell, sell any option or contract to 
purchase, purchase any option or contract to sell, grant any option, right or 
warrant to purchase, lend or otherwise transfer or dispose of, directly or 
indirectly, any shares of Common Stock or any securities convertible into or 
exercisable or exchangeable for Common Stock, or (2) enter into any swap or 
other agreement that transfers to another, in whole or in part, any of the 
economic consequences of ownership of the Common Stock, whether any such 
transaction described in clause (1) or (2) above is to be settled by delivery 
of Common Stock or such other securities, in cash or otherwise.  The 
foregoing sentence shall not apply to transactions relating to shares of 
Common Stock or other securities acquired in open market transactions after 
the completion of the Public Offering.  In addition, the undersigned agrees 
that, without the prior written consent of Morgan Stanley on behalf of the 
Underwriters, it will not, during the period commencing on the date hereof 
and ending 90 days after the date of the Prospectus, make any demand for or 
exercise any right with respect to, the registration of any shares of Common 
Stock or any security convertible into or exercisable or exchangeable for 
Common Stock.  

  Whether or not the Public Offering actually occurs depends on a number of 
factors, including market conditions.  Any Public Offering will only be made 
pursuant to an Underwriting Agreement, the terms of which are subject to 
negotiation between the Company and the Underwriters.    



                           Very truly yours,
