     (a)  "Preferred Securities." 700,000 Preferred Securities of the Trust with
          an aggregate liquidation preference with respect to the assets of the
          Trust of thirty-five million dollars ($35,000,000), and a liquidation
          preference with respect to the assets of the Trust of $50 per
          Preferred Security, are hereby designated for the purposes of
          identification only as "7.16% Convertible Preferred Securities
          (liquidation preference $50 per Convertible Preferred Security)" (the
          "Preferred Securities"). The Preferred Security Certificates
          evidencing the Preferred Securities shall be substantially in the form
          attached hereto as Exhibit A-1 and Exhibit A-2, with such changes and
          additions thereto or deletions therefrom as may be required by
          ordinary usage, custom or practice or to conform to the rules of any
          stock exchange or other organization on which the Preferred Securities
          are listed.

     (b)  "Common Securities." 43,300 Common Securities of the Trust with an
          aggregate liquidation amount with respect to the assets of the Trust
          of two million one hundred sixty-five thousand dollars ($2,165,000),
          and a liquidation amount with respect to the assets of the Trust of
          $50 per Common Security, are hereby designated for the purposes of
          identification only as "7.16% Convertible Common Securities
          (liquidation amount $50 per Convertible Common Security)" (the "Common
          Securities"). The Common Security Certificates evidencing the Common
          Securities shall be substantially in the form attached hereto as
          Exhibit A-3, with such changes and additions thereto or deletions
          therefrom as may be required by ordinary usage, custom or practice.

2.       Distributions.

     (a)  Distributions payable on each Security will be fixed at a rate per
          annum of 7.16% (the "Coupon Rate") of the stated liquidation amount of
          $50 per Security, such

<PAGE>

          rate being the rate of interest payable on the Debentures to be held
          by the Property Trustee. Distributions in arrears for more than one
          quarter will bear interest thereon compounded quarterly at the Coupon
          Rate (to the extent permitted by applicable law). The term
          "Distributions" as used herein includes such cash distributions and
          any such interest payable unless otherwise stated. A Distribution is
          payable only to the extent that payments are made in respect of the
          Debentures held by the Property Trustee and to the extent the Property
          Trustee has funds available therefor. The amount of Distributions
          payable for any period will be computed for any full quarterly
          Distribution period on the basis of a 360-day year of twelve 30-day
          months, and for any period shorter than a full quarterly Distribution
          period for which Distributions are computed, Distributions will be
          computed on the basis of the actual number of days elapsed per 30-day
          month.

     (b)  Distributions on the Securities will be cumulative, will accrue from
          July 3, 2004 will be payable quarterly in arrears, on the following
          dates, which dates correspond to the interest payment dates on the
          Debentures: March 31, June 30, September 30 and December 31 of each
          year, commencing on September 30, 2004, except as otherwise described
          below. At any time following October 1, 2004, if the Sponsor has made
          the payment of interest due on the Debentures on September 30, 2004,
          the Sponsor has the right under the Indenture to defer payments of
          interest by extending the interest payment period from time to time on
          the Debentures for a period not exceeding 20 consecutive quarters
          (each an "Extension Period") and, as a consequence of such deferral,
          Distributions will also be deferred. Despite such deferral, quarterly
          Distributions will continue to accrue with interest thereon (to the
          extent permitted by applicable law) at the Coupon Rate compounded
          quarterly during any such Extension Period. Prior to the termination
          of any such Extension Period, the Sponsor may further extend such
          Extension Period; provided that such Extension Period together with
          all such previous and further extensions thereof may not exceed 20
          consecutive quarters or extend beyond the maturity (whether at the
          stated maturity or by declaration of acceleration, call for redemption
          or otherwise) of the Debentures under the Indenture. Payments of
          accrued Distributions will be payable to Holders as they appear on the
          books and records of the Trust on the first record date after the end
          of the Extension Period. Upon the termination of any Extension Period
          and the payment of all amounts then due, the Sponsor may commence a
          new Extension Period, subject to the above requirements. In the event
          the Sponsor fails to make the payment of interest due on September 30,
          2004, the Sponsor shall permanently forego its right to avail itself
          of any Extension Period.

     (c)  Distributions on the Securities will be payable to the Holders thereof
          as they appear on the books and records of the Trust on the relevant
          record dates. The relevant record dates shall be one day prior to the
          relevant payment dates, except as otherwise described in this Annex I
          to the Declaration. Subject to any applicable laws and regulations and
          the provisions of the Declaration, each such payment in respect of
          Preferred Securities being held in book-entry form through The
          Depository Trust Company (the "Depositary") will be made as described
          in Section 2(f) below. The relevant record dates for the Common
          Securities shall be

                                       2
<PAGE>

          the same record dates as for the Preferred Securities. Distributions
          payable on any Securities that are not punctually paid on any
          Distribution payment date, as a result of the Sponsor having failed to
          make a payment under the Debentures, will cease to be payable to the
          Person in whose name such Securities are registered on the relevant
          record date, and such defaulted Distribution will instead be payable
          to the Person in whose name such Securities are registered on the
          special record date or other specified date determined in accordance
          with the Indenture. If any date on which Distributions are payable on
          the Securities is not a Business Day, then payment of the Distribution
          payable on such date will be made on the next succeeding day that is a
          Business Day (and without any interest or other payment in respect of
          any such delay) except that, if such Business Day is in the next
          succeeding calendar year, such payment shall be made on the
          immediately preceding Business Day, in each case with the same force
          and effect as if made on such date.

     (d)  In the event of an election by the Holder to convert its Securities
          through the Conversion Agent into DT Common Stock pursuant to the
          terms of the Securities as forth in this Annex I to the Declaration,
          no payment, allowance or adjustment shall be made with respect to
          accumulated and unpaid Distributions on such Securities, or be
          required to be made; provided that Holders of Securities
          at the close of business on any record date for the payment of
          Distributions will be entitled to receive the Distributions payable on
          such Securities on the corresponding payment date notwithstanding the
          conversion of such Securities into DT Common Stock following such
          record date.

     (e)  In the event that there is any money or other property held by or for
          the Trust that is not accounted for hereunder, such property shall be
          distributed Pro Rata (as defined herein) among the Holders of the
          Securities.

     (f)  Distributions on the Securities held in book-entry form will be made
          to the Depository in immediately available funds. The Depository's
          practice is to credit the direct participants' accounts on the
          relevant payment date in accordance with their respective holdings
          shown on the Depository's records unless the Depository has reason to
          believe that it will not receive payments on such payment date.
          Payments by participants to beneficial owners will be governed by
          standing instructions and customary practices and will be the
          responsibility of such participants and not of the Depository, the
          Trust or the Sponsor, subject to any statutory or regulatory
          requirements as may be in effect from time to time. Payment of
          distributions to the Depository is the responsibility of the Trust,
          disbursement of such payments to Participants is the responsibility of
          the Depository, and disbursement of such payments to the beneficial
          owners is the responsibility of participants.

3.       Liquidation Distribution Upon Dissolution.

          In the event of any voluntary or involuntary dissolution of the Trust,
the Holders of the Securities on the date of the dissolution will be entitled to
receive out of the assets of the

                                       3
<PAGE>

Trust available for distribution to Holders of Securities, after paying or
making reasonable provision to pay all claims and obligations of the Trust in
accordance with Section 3808(e) of the Business Trust Act, an amount equal to
the aggregate of the stated liquidation amount of $50 per Security plus accrued
and unpaid Distributions thereon to the date of payment (such amount being the
"Liquidation Distribution"), unless, in connection with such dissolution, after
paying or making reasonable provision to pay all claims and obligations of the
Trust in accordance with Section 3808(e) of the Business Trust Act, Debentures
in an aggregate principal amount equal to the aggregate stated liquidation
amount of such Securities, with an interest rate equal to the Coupon Rate of,
and bearing accrued and unpaid interest in an amount equal to the accrued and
unpaid Distributions on, such Securities, shall be distributed on a Pro Rata
basis to the Holders of the Securities in exchange for such Securities.

          If, upon any such dissolution, the Liquidation Distribution can be
paid only in part because the Trust has insufficient assets available to pay in
full the aggregate Liquidation Distribution, then the amounts payable directly
by the Trust on the Securities shall be paid on a Pro Rata basis in accordance
with paragraph 9.

4.   Redemption and Distribution.

     (a)  Upon the repayment or payment of the Debentures in whole or in part,
          whether at maturity or upon redemption or otherwise, the proceeds from
          such repayment or redemption shall be simultaneously applied to redeem
          Securities having an aggregate liquidation amount equal to the
          aggregate principal amount of the Debentures so repaid or redeemed at
          a redemption price of $50 per Security together with accrued and
          unpaid Distributions thereon through the date of the redemption,
          payable in cash (the "Redemption Price"). Holders will be given not
          less than 30 nor more than 60 days' notice of such redemption. Upon
          the repayment of the Debentures at maturity or upon any acceleration,
          earlier redemption or otherwise, the proceeds from such repayment will
          be applied to redeem the Securities, in whole, upon not less than 30
          nor more than 60 days' notice.

     (b)  If fewer than all the outstanding Securities are to be so redeemed,
          the Common Securities and the Preferred Securities will be redeemed
          Pro Rata and the Preferred Securities to be redeemed will be as
          described in paragraph 4(e)(ii) below.

     (c)  If, at any time, a Tax Event shall occur and be continuing the Sponsor
          shall cause the Regular Trustees to liquidate the Trust and, after
          paying or making reasonable provision to pay all claims and
          obligations of the Trust in accordance with Section 3808(e) of the
          Business Trust Act, cause Debentures to be distributed to the Holders
          of the Securities in liquidation of the Trust within 90 days following
          the occurrence of such Tax Event (the "90 Day Period"); provided,
          however, that such liquidation and distribution shall be conditioned
          on (i) the Regular Trustees' receipt of an opinion of a nationally
          recognized independent tax counsel experienced in such matters (a "No
          Recognition Opinion"), which opinion may rely on published revenue
          rulings of the Internal Revenue Service, to the effect

                                       4
<PAGE>

          that the Holders of the Securities will not recognize any income, gain
          or loss for United States federal income tax purposes as a result of
          such liquidation and distribution of Debentures, and (ii) the Sponsor
          being unable to avoid such Tax Event within such 90-day period by
          taking some ministerial action or pursuing some other reasonable
          measure that, in the sole judgment of the Sponsor, will have no
          adverse effect on the Trust, the Sponsor or the Holders of the
          Securities and will involve no material cost ("Ministerial Action").

                 If (i) the Sponsor has received an opinion (a "Redemption Tax
          Opinion") of a nationally recognized independent tax counsel
          (reasonably acceptable to the Regular Trustees) experienced in such
          matters that, as a result of a Tax Event, there is more than an
          insubstantial risk that the Sponsor would be precluded from deducting
          the interest on the Debentures for United States federal income tax
          purposes, even after the Debentures were distributed to the Holders of
          Securities upon liquidation of the Trust as described in this
          paragraph 4(c), or (ii) the Regular Trustees shall have been informed
          by such tax counsel that it cannot deliver a No Recognition Opinion,
          the Sponsor shall have the right, upon not less than 30 nor more than
          60 days' notice, and within 90 days following the occurrence of such
          Tax Event, to redeem the Debentures in whole (but not in part) for
          cash, at par plus accrued and unpaid interest and, following such
          redemption, all the Securities will be redeemed by the Trust at the
          liquidation preference of $50 per Security plus accrued and unpaid
          distributions; provided, however, that, if at the time there is
          available to the Sponsor or the Trust the opportunity to eliminate,
          within such 90 day period, the Tax Event by taking some Ministerial
          Action, the Trust or the Sponsor will pursue such Ministerial Action
          in lieu of redemption.

                  "Tax Event" means that the Sponsor shall have received an
          opinion of a nationally recognized independent tax counsel (reasonably
          acceptable to the Regular Trustees) experienced in such matters (a
          "Dissolution Tax Opinion") to the effect that as a result of (a) any
          amendment to, or change (including any announced prospective change
          (which shall not include a proposed change), provided that a Tax Event
          shall not occur more than 90 days before the effective date of any
          such prospective change) in, the laws (or any regulations thereunder)
          of the United States or any political subdivision or taxing authority
          therefor or therein, or (b) any amendment to, or change in, an
          interpretation or application of any such laws or regulations by any
          legislative body, court, governmental agency or regulatory authority
          (including the enactment of any legislation and the publication of any
          judicial decision or regulatory determination on or after the date of
          the Offering Memorandum), which amendment or change is effective or
          which interpretation or pronouncement is announced on or after the
          date of the Offering Memorandum, there is more than an insubstantial
          risk that (i) the Trust is or will be subject to United States federal
          income tax with respect to interest received on the Debentures, (ii)
          the Trust is, or will be within 90 days of the date thereof, subject
          to more than a de minimis amount of taxes, duties or other
          governmental charges, or (iii) interest paid in cash by the Sponsor to
          the Trust on

                                       5
<PAGE>

          the Debentures is not or will not be deductible by the Sponsor for
          United States federal income tax purposes.

               If an Investment Company Event (as hereinafter defined) shall
          occur and be continuing, the Sponsor shall cause the Regular Trustees
          to liquidate the Trust and, after paying or making reasonable
          provision to pay all claims and obligations of the Trust in accordance
          with Section 3808(e) of the Business Trust Act, cause the Debentures
          to be distributed to the Holders of the Securities in liquidation of
          the Trust within 90 days following the occurrence of such Investment
          Company Event.

               "Investment Company Event" means the occurrence of a change in
          law or regulation or a written change in interpretation or application
          of law or regulation by any legislative body, court, governmental
          agency or regulatory authority (a "Change in 1940 Act Law"), to the
          effect that the Trust is or will be considered an Investment Company
          which is required to be registered under the Investment Company Act,
          which Change in 1940 Act Law becomes effective on or after the date of
          the Offering Memorandum.

               After the date fixed for any distribution of Debentures: (i) the
          Securities will no longer be deemed to be outstanding, (ii) the
          Depositary or its nominee (or any successor Clearing Agency or its
          nominee), as record Holder of Preferred Securities represented by
          global certificates, will receive a registered global certificate or
          certificates representing the Debentures to be delivered upon such
          distribution and (iii) any certificates representing Securities,
          except for certificates representing Preferred Securities held by the
          Depositary or its nominee (or any successor Clearing Agency or its
          nominee), will be deemed to represent Debentures having an aggregate
          principal amount equal to the aggregate stated liquidation amount of
          such Securities, with accrued and unpaid interest equal to accrued and
          unpaid Distributions on such Securities until such certificates are
          presented to the Sponsor or its agent for transfer or reissuance.

     (d)  The Securities will not be redeemed unless all accrued and unpaid
          Distributions have been paid on all Securities for all quarterly
          Distribution periods terminating on or before the date of redemption.

     (e)  "Redemption or Distribution Procedures."

          (i)     Notice of any redemption of, or notice of distribution of
                  Debentures in exchange for the Securities (a "Redemption/
                  Distribution Notice") will be given by the Trust by mail to
                  each Holder of Securities to be redeemed or exchanged not
                  fewer than 30 nor more than 60 days before the date fixed for
                  redemption or exchange thereof which, in case of a redemption,
                  will be the date fixed for redemption of the Debentures. For
                  purposes of the calculation of the date of redemption or
                  exchange and the dates on which notices are given pursuant to
                  this paragraph 4(e)(i), a Redemption/Distribution Notice shall
                  be deemed to be given on the day

                                       6
<PAGE>

                  such notice is first mailed by first-class mail, postage
                  prepaid, to Holders of Securities. Each Redemption/
                  Distribution Notice shall be addressed to the Holders of
                  Securities at the address of each such Holder appearing in the
                  books and records of the Trust. No defect in the
                  Redemption/Distribution Notice or in the mailing of either
                  thereof with respect to any Holder shall affect the validity
                  of the redemption or exchange proceedings with respect to any
                  other Holder.

          (ii)    In the event that fewer than all the outstanding Securities
                  are to be redeemed, the Securities to be redeemed shall be
                  redeemed Pro Rata from each Holder of Common Securities and
                  Preferred Securities, it being understood that, in respect of
                  Preferred Securities registered in the name of and held of
                  record by the Depositary (or any successor Clearing Agency) or
                  any nominee, the distribution of the proceeds of such
                  redemption will be made to each Clearing Agency Participant
                  (or Person on whose behalf such nominee holds such securities)
                  in accordance with the procedures applied by such agency or
                  nominee.

          (iii)   If Securities are to be redeemed and the Trust gives a
                  Redemption/Distribution Notice, which notice may only be
                  issued if the Debentures are redeemed as set out in this
                  paragraph 4 (which notice will be irrevocable), then (A) with
                  respect to Preferred Securities held in book-entry form, by
                  12:00 noon, New York City time, on the redemption date,
                  provided that the Sponsor has paid the Property Trustee a
                  sufficient amount of cash in connection with the related
                  redemption or maturity of the Debentures, the Property Trustee
                  will deposit irrevocably with the Depositary (or successor
                  Clearing Agency) funds sufficient to pay the amount payable on
                  redemption with respect to such Preferred Securities and will
                  give the Depositary irrevocable instructions and authority to
                  pay the amount payable on redemption to the Holders of such
                  Preferred Securities, and (B) with respect to Preferred
                  Securities issued in certificated form and Common Securities,
                  provided that the Sponsor has paid the Property Trustee a
                  sufficient amount of cash in connection with the related
                  redemption or maturity of the Debentures, the Property Trustee
                  will irrevocably deposit with the Paying Agent funds
                  sufficient to pay the amount payable on redemption to the
                  Holders of such Securities upon surrender of their
                  certificates. If a Redemption/Distribution Notice shall have
                  been given and funds deposited as required, then on the date
                  of such deposit, all rights of Holders of such Securities so
                  called for redemption will cease, except the right of the
                  Holders of such Securities to receive the redemption price,
                  but without interest on such redemption price. Neither the
                  Regular Trustees nor the Trust shall be required to register
                  or cause to be registered the transfer of any Securities that
                  have been so called for redemption. If any date fixed for
                  redemption of Securities is not a Business Day, then payment
                  of the amount payable on such date will be made on the next
                  succeeding day that is a Business Day (without any interest or
                  other payment in respect of any such delay) except that, if
                  such

                                    7

<PAGE>
                  Business Day falls in the next calendar year, such payment
                  will be made on the immediately preceding Business Day, in
                  each case with the same force and effect as if made on such
                  date fixed for redemption. If payment of the redemption price
                  in respect of any Securities is improperly withheld or refused
                  and not paid either by the Trust or by the Sponsor as
                  guarantor pursuant to the relevant Securities Guarantee,
                  Distributions on such Securities will continue to accrue at
                  the then applicable rate, from the original redemption date to
                  the date of payment, in which case the actual payment date
                  will be considered the date fixed for redemption for purposes
                  of calculating the amount payable upon redemption (other than
                  for purposes of calculating any premium).

          (iv)    Redemption/Distribution Notices shall be sent by the Regular
                  Trustees on behalf of the Trust to (A) in the case of
                  Preferred Securities held in book-entry form, the Depositary
                  and, in the case of Securities held in certificated form, the
                  Holders of such certificates and (B) in respect of the Common
                  Securities, the Holder thereof.

          (v)     Subject to the foregoing and applicable law (including,
                  without limitation, United States federal securities laws),
                  the Sponsor or any of its subsidiaries may at any time and
                  from time to time purchase outstanding Preferred Securities by
                  tender, in the open market or by private agreement.

5.       Conversion Rights.

         The Holders of Securities shall have the right at any time, at their
option, to cause the Conversion Agent to convert Securities, on behalf of the
converting Holders, into shares of DT Common Stock in the manner described
herein on and subject to the following terms and conditions:

         (a)  The Securities will be convertible at the office of the Conversion
              Agent into fully paid and nonassessable shares of DT Common Stock
              pursuant to the Holder's direction to the Conversion Agent to
              exchange such Securities for a portion of the Debentures
              theretofore held by the Property Trustee on the basis of one
              Security per $50 principal amount of Debentures, and immediately
              convert such amount of Debentures into fully paid and
              nonassessable shares of DT Common Stock at an initial rate of
              3.5714 shares of DT Common Stock per $50 principal amount of
              Debentures (which is equivalent to a conversion price of $14.00
              per share of DT Common Stock, subject to certain adjustments set
              forth in the terms of the Debentures (as so adjusted, "Conversion
              Price")).

         (b)  In order to convert Securities into DT Common Stock the Holder
              shall submit to the Conversion Agent at the office referred to
              above an irrevocable request to convert Securities on behalf of
              such Holder (the "Conversion Request"), together, if the
              Securities are in certificated form, with such certificates. The
              Conversion Request shall (i) set forth the number of Securities to
              be converted and the name or names, if other than the Holder, in
              which the shares of DT Common Stock

                                       8
<PAGE>

              should be issued and (ii) direct the Conversion Agent (a) to
              exchange such Securities for a portion of the Debentures held by
              the Property Trustee (at the rate of exchange specified in the
              preceding paragraph) and (b) to immediately convert such
              Debentures on behalf of such Holder, into DT Common Stock (at the
              conversion rate specified in the preceding paragraph). The
              Conversion Agent shall notify the Trust of the Holder's election
              to exchange Securities for a portion of the Debentures held by the
              Property Trustee and the Trust shall, upon receipt of such notice,
              deliver to Conversion Agent the appropriate principal amount of
              Debentures for exchange in accordance with this Section. The
              Conversion Agent shall thereupon notify the Sponsor of the
              Holder's election to convert such Debentures into shares of DT
              Common Stock. Holders of Securities at the close of business on a
              Distribution record date will be entitled to receive the
              Distribution payable on such securities on the corresponding
              Distribution payment date notwithstanding the conversion of such
              Securities following such record date but prior to such
              distribution payment date. Except as provided above, neither the
              Trust nor the Sponsor will make, or be required to make any
              payment, allowance or adjustment upon any conversion on account of
              any accumulated and unpaid Distributions accrued on the Securities
              (including any Additional Amounts accrued thereon) surrendered for
              conversion, or on account of any accumulated and unpaid dividends
              on the shares of DT Common Stock issued upon such conversion.
              Securities shall be deemed to have been converted immediately
              prior to the close of business on the day on which a Notice of
              Conversion relating to such Securities is received by the Trust in
              accordance with the foregoing provision (the "Conversion Date").
              The Person or Persons entitled to receive the DT Common Stock
              issuable upon conversion of the Debentures shall be treated for
              all purposes as the record holder or holders of such DT Common
              Stock at such time. As promptly as practicable on or after the
              Conversion Date, the Sponsor shall issue and deliver at the office
              of the Conversion Agent a certificate or certificates for the
              number of full shares of DT Common Stock issuable upon such
              conversion, together with the cash payment, if any, in lieu of any
              fraction of any share to the Person or Persons entitled to receive
              the same, unless otherwise directed by the Holder in the notice of
              conversion and the Conversion Agent shall distribute such
              certificate or certificates to such Person or Persons.

         (c)  Each Holder of a Security by his acceptance thereof appoints The
              Bank of New York "Conversion Agent" for the purpose of effecting
              the conversion of Securities in accordance with this Section. In
              effecting the conversion and transactions described in this
              Section, the Conversion Agent shall be acting as agent of the
              Holders of Securities directing it to effect such conversion
              transactions. The Conversion Agent is hereby authorized (i) to
              exchange Securities from time to time for Debentures held by the
              Property Trustee in connection with the conversion of such
              Securities in accordance with this Section and (ii) to convert all
              or a portion of the Debentures into DT Common Stock and thereupon
              to deliver such shares of DT Common Stock in accordance with the
              provisions of this Section and to deliver to the Property Trustee
              a new Debenture or Debentures for any resulting unconverted
              principal amount.

                                       9
<PAGE>

         (d)  No fractional shares of DT Common Stock will be issued as a result
              of conversion, but in lieu thereof, such fractional interest will
              be paid in cash by the Sponsor to the Trust, which in turn will
              make such payment to the Holder or Holders of Securities so
              converted.

         (e)  The Sponsor shall at all times reserve and keep available out of
              its authorized and unissued DT Common Stock, solely for issuance
              upon the conversion of the Debentures, free from any preemptive or
              other similar rights, such number of shares of DT Common Stock as
              shall from time to time be issuable upon the conversion of all the
              Debentures then outstanding. Notwithstanding the foregoing, the
              Sponsor shall be entitled to deliver upon conversion of
              Debentures, shares of DT Common Stock reacquired and held in the
              treasury of the Sponsor (in lieu of the issuance of authorized and
              unissued shares of DT Common Stock), so long as any such treasury
              shares are free and clear of all liens, charges, security
              interests or encumbrances. Any shares of DT Common Stock issued or
              delivered upon conversion of the Debentures shall be duly
              authorized, validly issued and fully paid and nonassessable. The
              Trust shall deliver the shares of DT Common Stock received upon
              conversion of the Debentures to the converting Holder free and
              clear of all liens, charges, security interests and encumbrances,
              except for United States withholding taxes. Each of the Sponsor
              and the Trust shall prepare and shall use its best efforts to
              obtain and keep in force such governmental or regulatory permits
              or other authorizations as may be required by law, and shall
              comply with all applicable requirements as to registration or
              qualification of the DT Common Stock (and all requirements to list
              the DT Common Stock issuable upon conversion of Debentures that
              are at the time applicable), in order to enable the Sponsor to
              lawfully issue DT Common Stock to the Trust upon conversion of the
              Debentures and the Trust to lawfully deliver the DT Common Stock
              to each Holder upon conversion of the Securities.

         (f)  The Sponsor will pay any and all taxes that may be payable in
              respect of the issue or delivery of shares of DT Common Stock on
              conversion of Debentures and the delivery of the shares of DT
              Common Stock by the Trust upon conversion of the Securities. The
              Sponsor shall not, however, be required to pay any tax which may
              be payable in respect of any transfer involved in the issue and
              delivery of shares of DT Common Stock in a name other than that in
              which the Securities so converted were registered, and no such
              issue or delivery shall be made unless and until the person
              requesting such issue has paid to the Trust the amount of any such
              tax, or has established to the satisfaction of the Trust that such
              tax has been paid.

         (g)  Nothing in the preceding paragraph (f) shall limit the requirement
              of the Trust to withhold taxes pursuant to the terms of the
              Securities or set forth in this Annex I to the Declaration or to
              the Declaration itself or otherwise require the Property Trustee
              or the Trust to pay any amounts on account of such withholdings.

         (a)  Except as provided under paragraphs 6(b) and 8, in the Business
              Trust Act and as otherwise required by law, the Declaration and
              the Indenture, the Holders of the Preferred Securities will have
              no voting rights.

         (b)  In addition to the rights of the Holders of the Preferred
              Securities with respect to the enforcement of payment of principal
              and interest on the Debentures set forth herein, in the
              Declaration or in the Indenture, if (i) the Trust fails to make
              Distributions in full on the Preferred Securities for six (6)
              consecutive quarterly Distribution periods (whether or not an
              Extended Interest Payment Period is in effect), or (ii) an Event
              of Default occurs and is continuing (each of (i) and (ii) being an
              "Appointment Event"), then the Holders of the Preferred
              Securities, acting as a single class, will be entitled by the vote
              of a Majority in liquidation preference of the Preferred
              Securities to appoint a Special Regular Trustee in accordance with
              Section 5.06(a)(ii)(B) of the Declaration. Any Holder of Preferred
              Securities (other than the Sponsor, or any entity directly or
              indirectly controlling or controlled by or under direct or
              indirect common control with the Sponsor) will be entitled to
              nominate any person to be appointed as Special Regular Trustee.
              For purposes of determining whether the Trust has failed to make
              Distributions in full for 6 consecutive quarterly Distribution
              periods, Distributions shall be deemed to remain in arrears,
              notwithstanding any payments in respect thereof, until full
              cumulative Distributions have been or contemporaneously are paid
              with respect to all quarterly Distribution periods terminating on
              or prior to the date of payment of such cumulative Distributions.
              Not later than 30 days after such right to appoint a Special
              Regular Trustee arises, the Regular Trustees will convene a
              meeting for the purpose of appointing a Special Regular Trustee.
              If the Regular Trustees fail to convene such meeting within such
              30-day period, the Holders of not less than 10% in aggregate
              liquidation preference of the Preferred Securities will be
              entitled to convene such meeting in accordance with Section 12.02
              of the Declaration. The record date for such meeting will be the
              close of business on the Business Day that is one Business Day
              before the day on which notice of the meeting is sent to the
              Holders. The provisions of the Declaration relating to the
              convening and conduct of the meetings of the Holders will apply
              with respect to any such meeting.

              Any Special Regular Trustee so appointed shall cease to be a
              Special Regular Trustee if the Appointment Event pursuant to which
              the Special Regular Trustee was appointed and all other
              Appointment Events cease to be continuing. A Special Regular
              Trustee may be removed without cause at any time by vote of the
              Holders of a Majority in liquidation preference of the Preferred
              Securities at a meeting of the Holders of the Preferred Securities
              in accordance with Section 5.06(a)(ii)(B) of the Declaration. The
              Holders of 10% in liquidation preference of the Preferred
              Securities will be entitled to convene such a meeting in
              accordance with Section 12.02 of the Declaration. The record date
              for such meeting will be the close of business on the Business Day
              which is one Business Day before the day on which the notice of
              meeting is sent to Holders. Notwithstanding the appointment of a
              Special Regular Trustee, the Sponsor shall retain all rights under

                                       11
<PAGE>

              the Indenture, including the right to extend the interest payment
              period on the Debentures.

              Subject to the requirements set forth in this paragraph, the
              Holders of a majority in liquidation preference of the Preferred
              Securities, voting separately as a class may direct the time,
              method, and place of conducting any proceeding for any remedy
              available to the Property Trustee, or direct the exercise of any
              trust or power conferred upon the Property Trustee under the
              Declaration, including the right to direct the Property Trustee,
              as holder of the Debentures, to (i) exercise the remedies
              available under the Indenture with respect to the Debentures, (ii)
              waive any past default and its consequences that is waiveable
              under Section 5.13 of the Indenture or otherwise, (iii) exercise
              any right to rescind or annul a declaration that the principal of
              all the Debentures shall be due and payable or (iv) consent to any
              amendment, modification or termination of the Indenture or the
              Debentures, where such consent shall be required, provided,
              however, that, where a consent under the Indenture would require
              the consent or act of the Holders of greater than a majority of
              the Holders in principal amount of Debentures affected thereby (a
              "Super Majority"), the Property Trustee may only give such consent
              or take such action at the direction of the Holders of at least
              the proportion in liquidation preference of the Preferred
              Securities which the relevant Super Majority represents of the
              aggregate principal amount of the Debentures outstanding. The
              Property Trustee shall not, and none of the other Trustees shall
              in any event, revoke any action previously authorized or approved
              by a vote of the Holders of the Preferred Securities, except by a
              subsequent vote of the Holders of the Preferred Securities. Other
              than with respect to directing the time, method and place of
              conducting any remedy available to the Property Trustee or the
              Debenture Trustee as set forth above, the Property Trustee shall
              not take any action in accordance with the directions of the
              Holders of the Preferred Securities under this paragraph unless
              the Property Trustee has obtained an opinion of tax counsel to the
              effect that, as a result of such action, the Trust will not fail
              to be classified as a grantor trust for United States federal
              income tax purposes.

              If the Property Trustee is the sole holder of the Debentures, any
              Holder of the Preferred Securities shall have the right to
              institute suit on behalf of the Trust for the enforcement of the
              right to receive payment of the principal of and interest on the
              Debentures on or after the Stated Maturity (as defined in the
              Indenture) of such Debentures or, in the case of redemption, on
              the Redemption Date (as defined in the Indenture), and the right
              to convert the Debentures in accordance with the Indenture. In
              addition, the Holders of at least 25% in aggregate liquidation
              preference of Preferred Securities outstanding shall be entitled
              to institute any other proceeding in the event the Debenture
              Trustee or the Property Trustee fails to do so in accordance with
              the terms of the Indenture.

              In addition to any other rights of the Holders provided herein or
              in the Declaration, if the Property Trustee fails to enforce its
              rights, as holder of the Debentures, under the Indenture, any
              Holder of Preferred Securities may, after a period of 30 days has
              elapsed from such Holder's written request to the Property

                                       12
<PAGE>

              Trustee to enforce such rights, institute a legal proceeding
              directly against the Sponsor, to enforce the rights of the
              Property Trustee, as holder of the Debentures, under the
              Indenture, without first instituting any legal proceeding against
              the Property Trustee or any other Person.

              Any approval or direction of Holders of Preferred Securities may
              be given at a separate meeting of Holders of Preferred Securities
              convened for such purpose, at a meeting of all of the Holders of
              Securities in the Trust or pursuant to written consent. The
              Regular Trustees will cause a notice of any meeting at which
              Holders of Preferred Securities are entitled to vote, or of any
              matter upon which action by written consent of such Holders is to
              be taken, to be mailed to each Holder of record of Preferred
              Securities. Each such notice will include a statement setting

              the date by which such action is to be taken, (ii) a description
              of any resolution proposed for adoption at such meeting on which

              of proxies or consents.

              No vote or consent of the Holders of the Preferred Securities will

              Securities or to distribute the Debentures in accordance with the
              Declaration and the terms of the Securities.

              Notwithstanding that Holders of Preferred Securities are entitled
              to vote or consent under any of the circumstances described above,
              any of the Preferred Securities that are owned by the Sponsor or
              any Affiliate of the Sponsor shall not be entitled to vote or
              consent and shall, for purposes of such vote or consent, be
              treated as if they were not outstanding.

7.       Voting Rights - Common Securities.

         (a)  Except as provided under paragraphs 7(b), (c) and 8, in the
              Business Trust Act and as otherwise required by law and the
              Declaration, the Holders of the Common Securities will have no
              voting rights.

         (b)  The Holders of the Common Securities are entitled, in accordance
              with Article V of the Declaration, to vote to appoint, remove or
              replace any Trustee, subject to the exclusive right of the Holders
              of the Preferred Securities to appoint, remove or replace a
              Special Regular Trustee.

         (c)  Subject to Section 2.06 of the Declaration and only after the
              Event of Default with respect to the Preferred Securities has been
              cured, waived, or otherwise eliminated and subject to the
              requirements of the second to last sentence of this paragraph, the
              Holders of a Majority in liquidation amount of the Common
              Securities, voting separately as a class, may direct the time,
              method, and place of conducting any proceeding for any remedy
              available to the Property Trustee, or exercising any trust or
              power conferred upon the Property Trustee under the Declaration,
              including (i) directing the time, method, place of conducting any

                                       13

<PAGE>

              proceeding for any remedy available to the Debenture Trustee, or
              exercising any trust or power conferred on the Debenture Trustee
              with respect to the Debentures, (ii) waive any past default and
              its consequences that is waiveable under Section 6.06 of the
              Indenture, or (iii) exercise any right to rescind or annul a
              declaration that the principal of all the Debentures shall be due
              and payable, provided that, where a consent or action under the
              Indenture would require the consent or act of the Holders of
              greater than a majority in principal amount of Debentures affected
              thereby (a "Super Majority"), the Property Trustee may only give
              such consent or take such action at the direction of the Holders
              of at least the proportion in liquidation amount of the Common
              Securities which the relevant Super Majority represents of the
              aggregate principal amount of the Debentures outstanding. Pursuant
              to this paragraph 7(c), the Property Trustee shall not revoke any
              action previously authorized or approved by a vote of the Holders
              of the Preferred Securities, except by a subsequent vote of the
              Holders of the Preferred Securities. Other than with respect to
              directing the time, method and place of conducting any remedy
              available to the Property Trustee or the Debenture Trustee as set
              forth above, the Property Trustee shall not take any action in
              accordance with the directions of the Holders of the Common
              Securities under this paragraph unless the Property Trustee has
              obtained an opinion of tax counsel to the effect that, as a result
              of such action the Trust will not fail to be classified as a
              grantor trust for United States federal income tax purposes. If
              the Property Trustee fails to enforce its rights, as holder of the
              Debentures, under the Indenture, any Holder of Common Securities
              may, after a period of 30 days has elapsed from such Holder's
              written request to the Property Trustee to enforce such rights,
              institute a legal proceeding directly against the Sponsor, to
              enforce the Property Trustee's rights, as holder of the
              Debentures, under the Indenture, without first instituting any
              legal proceeding against the Property Trustee or any other Person.

              Any approval or direction of Holders of Common Securities may be
              given at a separate meeting of Holders of Common Securities
              convened for such purpose, at a meeting of all of the Holders of
              Securities in the Trust or pursuant to written consent. The
              Regular Trustees will cause a notice of any meeting at which
              Holders of Common Securities are entitled to vote, or of any
              matter upon which action by written consent of such Holders is to
              be taken, to be mailed to each Holder of record of Common
              Securities. Each such notice will include a statement setting
              forth (i) the date of such meeting or the date by which such
              action is to be taken, (ii) a description of any resolution
              proposed for adoption at such meeting on which such Holders are
              entitled to vote or of such matter upon which written consent is
              sought and (iii) instructions for the delivery of proxies or
              consents.

              No vote or consent of the Holders of the Common Securities will be
              required for the Trust to redeem and cancel Common Securities or
              to distribute the Debentures in accordance with the Declaration
              and the terms of the Securities.

8.       Amendments to Declaration and Indenture.

                                       14

<PAGE>

         (a)  In addition to any requirements under Section 12.01 of the
              Declaration, if any proposed amendment to the Declaration provides
              for, or the Regular Trustees otherwise propose to effect, (i) any
              action that would adversely affect the powers, preferences or
              special rights of the Securities, whether by way of amendment to
              the Declaration or otherwise, or (ii) the dissolution, winding up
              or termination of the Trust, other than as described in Section
              8.01 of the Declaration, then the Holders of outstanding
              Securities as a class, will be entitled to vote on such amendment
              or proposal (but not on any other amendment or proposal) and such
              amendment or proposal shall not be effective except with the
              approval of the Holders of at least 66-2/3% in liquidation amount
              of the Securities, voting together as a single class provided,
              however, that the rights of Holders of Preferred Securities under
              Article V of the Declaration to appoint, remove or replace a
              Special Regular Trustee shall not be amended without the consent
              of each Holder of Preferred Securities; provided, however, if any
              amendment or proposal referred to in clause (i) above would
              adversely affect only the Preferred Securities or only the Common
              Securities, then only the affected class will be entitled to vote
              on such amendment or proposal and such amendment or proposal shall
              not be effective except with the approval of 66-2/3% in
              liquidation amount of such class of Securities.

         (b)  In the event the consent of the Property Trustee as the holder of
              the Debentures is required under the Indenture with respect to any
              amendment, modification or termination of the Indenture or the
              Debentures, the Property Trustee shall request the direction of
              the Holders of the Securities with respect to such amendment,
              modification or termination and shall vote with respect to such
              amendment, modification or termination as directed by at least the
              same proportion in aggregate stated liquidation preference of the
              Securities; provided, however, that the Property Trustee shall not
              take any action in accordance with the directions of the Holders
              of the Securities under this paragraph 8(b) unless the Property
              Trustee has obtained an opinion of tax counsel to the effect that
              for the purposes of United States federal income tax the Trust
              will not be classified as other than a grantor trust on account of
              such action.

9.       Pro Rata.

              A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate liquidation amount of the Securities
held by the relevant Holder in relation to the aggregate liquidation amount of
all Securities outstanding unless, on any distribution date or redemption date
an Event of Default under the Declaration has occurred and is continuing, in
which case no payment of any distribution on, or amount payable upon redemption
of, any Common Security, and no other payment on account of the redemption,
liquidation or other acquisition of Common Securities, shall be made unless
payment in full in cash of all accumulated and unpaid distributions on all
outstanding Preferred Securities for all distribution periods terminating on or
prior thereto, or in the case of payment of the amount payable on redemption of
the Preferred Securities, the full amount of such amount in respect of all
outstanding Preferred Securities shall have been made or provided for, and all
funds available to

                                       15
<PAGE>

the Property Trustee shall first be applied to the payment in
full in cash of all distributions on, or the amount payable upon redemption of
Preferred Securities then due and payable.

10.      Ranking.

              The Preferred Securities rank pari passu and payment thereon
shall be made Pro Rata with the Common Securities except that, where an Event of
Default occurs and is continuing under the Indenture in respect of the
Debentures held by the Property Trustee, the rights of Holders of the Common
Securities to payment in respect of Distributions and payments upon liquidation,
redemption and otherwise are subordinated to the rights to payment of the
Holders of the Preferred Securities.

11.      Acceptance of Securities Guarantees and Indenture.

              Each Holder of Preferred Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Preferred Securities

              The Sponsor will provide a copy of the Declaration, the
Preferred Securities Guarantee or the Common Securities Guarantee (as may be
appropriate), and the Indenture to a Holder without charge on written request to
the Sponsor at its principal place of business.

         (liquidation preference $50 per Convertible Preferred Security)

                  DT Capital Trust, a statutory business trust formed under the

<PAGE>

                          [FORM OF REVERSE OF SECURITY]

                  Distributions payable on each Preferred Security will be fixed
at a rate per annum of 7.16% (the "Coupon Rate") of the stated liquidation
preference of $50 per Preferred Security, such rate being the rate of interest
payable on the Debentures to be held by the Property Trustee. Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law). The
term "Distributions" as used herein includes such cash distributions and any
such interest payable unless otherwise stated. A Distribution is payable only to
the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent the Property Trustee has funds available
therefor. The amount of Distributions payable for any period will be computed
for any full quarterly Distribution period on the basis of a 360-day year of
twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

                  Except as otherwise described below, distributions on the
Preferred Securities will be cumulative, will accrue from July 3, 2004 and will
be payable quarterly in arrears, on March 31, June 30, September 30 and December
31 of each year, commencing on September 30, 2004, to Holders of record one (1)
day prior to such payment dates, which payment dates shall correspond to the
interest payment dates on the Debentures. At any time after October 1, 2004, if
the Debenture Issuer has paid the interest due on the Debentures on September
30, 2004, the Debenture Issuer has the right under the Indenture to defer
payments of interest by extending the interest payment period from time to time
on the Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period") and, as a consequence of such deferral, Distributions will
also be deferred. Despite such deferral, quarterly Distributions will continue
to accrue with interest thereon (to the extent permitted by applicable law) at
the Coupon Rate compounded quarterly during any such Extension Period. Prior to
the termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity (whether at the stated maturity or by
declaration of acceleration, call for redemption or otherwise) of the Debentures
under the Indenture. Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the first record
date after the end of the Extension Period. Upon the termination of any
Extension Period and the payment of all amounts then due, the Debenture Issuer
may commence a new Extension Period, subject to the above requirements.

                  The Preferred Securities shall be redeemable as provided in
the Declaration.

                  The Preferred Securities shall be convertible into shares of
DT Common Stock, through (i) the exchange of Preferred Securities for a portion
of the Debentures and (ii) the immediate conversion of such Debentures into DT

<PAGE>

                          [FORM OF REVERSE OF SECURITY)

                  Distributions payable on each Preferred Security will be fixed
at a rate per annum of 7.16% (the "Coupon Rate") of the stated liquidation
preference of $50 per Preferred Security, such rate being the rate of interest
payable on the Debentures to be held by the Property Trustee. Distributions in
arrears for more than one quarter will bear interest thereon compounded
quarterly at the Coupon Rate (to the extent permitted by applicable law). The
term "Distributions" as used herein includes such cash distributions and any
such interest payable unless otherwise stated. A Distribution is payable only to
the extent that payments are made in respect of the Debentures held by the
Property Trustee and to the extent the Property Trustee has funds available
therefor. The amount of Distributions payable for any period will be computed
for any full quarterly Distribution period on the basis of a 360-day year of
twelve 30-day months, and for any period shorter than a full quarterly
Distribution period for which Distributions are computed, Distributions will be
computed on the basis of the actual number of days elapsed per 30-day month.

                  Except as otherwise described below, distributions on the
Preferred Securities will be cumulative, will accrue from July 3, 2004 and will
be payable quarterly in arrears, on March 31, June 30, September 30 and December
31 of each year, commencing on September 30, 2004, to Holders of record one (1)
day prior to such payment dates, which payment dates shall correspond to the
interest payment dates on the Debentures. At any time after October 1, 2004, if
the Debenture Issuer has paid the interest due on the Debentures on September
30, 2004, the Debenture Issuer has the right under the Indenture to defer
payments of interest by extending the interest payment period from time to time
on the Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period") and, as a consequence of such deferral, Distributions will
also be deferred. Despite such deferral, quarterly Distributions will continue
to accrue with interest thereon (to the extent permitted by applicable law) at
the Coupon Rate compounded quarterly during any such Extension Period. Prior to
the termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity (whether at the stated maturity or by
declaration of acceleration, call for redemption or otherwise) of the Debentures
under the Indenture. Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the first record
date after the end of the Extension Period. Upon the termination of any
Extension Period and the payment of all amounts then due, the Debenture Issuer
may commence a new Extension Period, subject to the above requirements.

                  The Preferred Securities shall be redeemable as provided in
the Declaration.

                  The Preferred Securities shall be convertible into shares of
DT Common Stock, through (i) the exchange of Preferred Securities for a portion
of the Debentures and (ii) the immediate conversion of such Debentures into DT
Common Stock, in the manner and according to the terms set forth in the
Declaration.

Amended and Restated Declaration of Trust of the Trust, dated as of June 1,
1997, as amended by the Amendment to Amended and Restated Declaration of Trust
dated as of June __, 2002 and as further amended from time to time (the

                  Reference is hereby made to select provisions of the Common
Securities set forth on the reverse hereof, which select provisions shall for
all purposes have the same effect as if set forth at this place.

                  Upon receipt of this certificate, the Sponsor is bound by the
Declaration and is entitled to the benefits thereunder.

                  By acceptance, the Holder agrees to treat for United States
federal income tax purposes the Debentures as indebtedness and the Common
Securities as evidence of indirect beneficial ownership in the Debentures.

                  IN WITNESS WHEREOF, the Trust has executed this certificate

                                 DT Capital Trust

                                 By:
                                    --------------------------------------------
                                 Name:
                                 Title.

                                     A-3-2
<PAGE>

                          [FORM OF REVERSE OF SECURITY]

                  Distributions payable on each Common Security will be fixed at
a rate per annum of 7.16% (the "Coupon Rate") of the stated liquidation amount
of $50 per Common Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one quarter will bear interest thereon compounded quarterly at the Coupon
Rate (to the extent permitted by applicable law). The term "Distributions" as
used herein includes such cash distributions and any such interest payable
unless otherwise stated. A Distribution is payable only to the extent that
payments are made in respect of the Debentures held by the Property Trustee and
to the extent the Property Trustee has funds available therefor. The amount of
Distributions payable for any period will be computed for any full quarterly
Distribution period on the basis of a 360-day year of twelve 30-day months, and
for any period shorter than a full quarterly Distribution period for which
Distributions are computed, Distributions will be computed on the basis of the
actual number of days elapsed per 30-day month.

                  Except as otherwise described below, distributions on the
Common Securities will be cumulative, will accrue from July 3, 2004 and will be
payable quarterly in arrears, on March 31, June 30, September 30 and December 31
of each year, commencing on September 30, 2004, to Holders of record one (1) day
prior to such payment dates, which payment dates shall correspond to the
interest payment dates on the Debentures. At any time after October 1, 2004, if
the Debenture Issuer has paid the interest due on the Debentures on September
30, 2004, the Debenture Issuer has the right under the Indenture to defer
payments of interest by extending the interest payment period from time to time
on the Debentures for a period not exceeding 20 consecutive quarters (each an
"Extension Period") and, as a consequence of such deferral, Distributions will
also be deferred. Despite such deferral, quarterly Distributions will continue
to accrue with interest thereon (to the extent permitted by applicable law) at
the Coupon Rate compounded quarterly during any such Extension Period. Prior to
the termination of any such Extension Period, the Debenture Issuer may further
extend such Extension Period; provided that such Extension Period together with
all such previous and further extensions thereof may not exceed 20 consecutive
quarters or extend beyond the maturity (whether at the stated maturity or by
declaration of acceleration, call for redemption or otherwise) of the Debentures
under the Indenture. Payments of accrued Distributions will be payable to
Holders as they appear on the books and records of the Trust on the first record
date after the end of the Extension Period. Upon the termination of any
Extension Period and the payment of all amounts then due, the Debenture Issuer
may commence a new Extension Period, subject to the above requirements.

                  The Common Securities shall be redeemable as provided in the
Declaration.

                  The Common Securities shall be convertible into shares of DT
Common Stock, through (i) the exchange of Common Securities for a portion of the
Debentures and (ii) the immediate conversion of such Debentures into DT Common
Stock, in the manner and according to the terms set forth in the Declaration.

immediately convert such Debentures on behalf of the undersigned, into DT Common
Stock (at the conversion rate specified in the terms of the Common Securities
set forth as Annex I to the Declaration).

                  The undersigned does also hereby direct the Conversion Agent

relating to the DT Common Stock issuable upon conversion of the Common
Securities.

         SECTION 1. RECITALS

         The recitals set forth above are incorporated herein by this reference.

         SECTION 2. DEFINITIONS

         Capitalized terms used but not defined herein shall have the meanings
given to them in the Original Indenture. As used herein, the following terms
shall have the meanings set forth below:

          "Effective Time" means immediately upon the consummation of the
Exchange (as defined in the Exchange Agreement).

          "Restructuring" means the concurrent consummation of each of the

         SECTION 3. ORGANIZATION OF AMENDMENTS

         Upon the Effective Time, the Original Indenture shall be amended and
supplemented in accordance herewith, and this First Supplemental Indenture shall
form a

                                       2
<PAGE>

part of the Original Indenture for all purposes, and every holder of Securities
theretofore or thereafter authenticated and delivered under the Original
Indenture shall be bound thereby, as hereby amended and supplemented; provided,
however, that the provisions of this First Supplemental Indenture shall not
become operative until the Effective Time (and at such time the provisions of
this First Supplemental Indenture shall automatically become operative without
the requirement of any further action by or notice to the Company, the Trustee,
the Property Trustee or any holder of the Preferred Securities).

         SECTION 4. AMENDMENTS TO THE ORIGINAL INDENTURE

         SECTION 4.1. Effective as of the Effective Time, Section 3.01 of the
Original Indenture is hereby amended and restated in its entirety to read as
follows:

                  "Section 3.01. Title and Terms. The aggregate principal amount
         of Securities that may be authenticated and delivered under this
         Indenture is limited to $37,165,000, except for Securities
         authenticated and delivered upon registration of transfer of, or in
         exchange for, or in lieu of, other Securities pursuant to Section 3.04,
         3.05, 3.06, 9.06, 11.08 or 13.01.

                  The Securities shall be known and designated as the "7.16%
         Convertible Junior Subordinated Deferrable Interest Debentures Due
         2008" of the Company. Their Stated Maturity shall be May 31, 2008, and
         they shall bear interest at the rate of 7.16% per annum, from July 3,
         2004 payable quarterly (subject to deferral as set forth herein), in
         arrears, on March 31, June 30, September 30 and December 31 (each an
         "Interest Payment Date") of each year, commencing September 30, 2004
         until the principal thereof is paid or made available for payment, and
         they shall be paid to the Person in whose name the Security is
         registered at the close of business on the regular record date for such
         interest installment, which shall be the close of business on the date
         which is one day prior to each Interest Payment Date (the "Regular
         Record Date"). Interest will compound quarterly and will accrue at the
         rate of 7.16% per annum on any interest installment in arrears for more
         than one quarter or during an extension of an interest payment period
         as set forth in Section 3.12 hereof.

                  The amount of interest payable for any period will be computed
         on the basis of a 360-day year of twelve 30-day months. Except as
         provided in the following sentence, the amount of interest payable for
         any period shorter than a full quarterly period for which interest is
         computed, will be computed on the basis of the actual number of days
         elapsed in such a 30-day month. In the event that any date on which

                  If at any time while the Property Trustee is the Holder of any
         Securities, the Trust or the Property Trustee is required to pay any
         taxes, duties, assessments or governmental charges of whatever nature
         (other than withholding taxes) imposed by the United States, or any
         other taxing authority, then, in any case, the Company will pay as
         additional interest ("Additional Interest") on the Securities held by
         the Property Trustee, such additional amounts as shall be required so
         that the net amounts received and retained by the Trust and the
         Property Trustee after paying such taxes, duties, assessments or other
         governmental charges will be equal to the amounts the Trust and the
         Property Trustee would have received had no such taxes, duties,
         assessments or other governmental charges been imposed.

                  The principal of and interest on the Securities shall be
         payable at the office or agency of the Company in the United States
         maintained for such purpose and at any other office or agency
         maintained by the Company for such purpose in such coin or currency of
         the United States of America as at the time of payment is legal tender
         for payment of public and private debts; provided, however, that at the
         option of the Company payment of interest may be made by check mailed
         to the address of the Person entitled thereto as such address shall
         appear in the Security Register.

                  The Securities shall be redeemable as provided in Article XI
         hereof.

                  The Securities shall be subordinated in right of payment to
         Senior Indebtedness as provided in Article XII hereof.

                  The Securities shall be convertible as provided in Article
         XIII hereof."

         SECTION 4.2. Effective as of the Effective Time, the first paragraph of
Section 3.07 of the Original Indenture is hereby amended and restated to read as
follows:

                           "From April 1, 2002 through and including July 2,
         2004, no interest shall accrue or be payable on any Security.
         Commencing on July 3, 2004, interest shall accrue on the outstanding
         principal of the Securities, and interest on any Security which is
         payable, and is punctually paid or duly provided for, on any Interest
         Payment Date shall be paid to the Person in whose name that Security
         (or one or more Predecessor Securities) is registered at the close of
         business on the Regular Record Date."

         SECTION 4.3. Effective as of the Effective Time, Section 3.12(a) of the
Original Indenture is hereby amended and restated in its entirety to read as
follows:

                                       4
<PAGE>

                  "Section 3.12. Extension of Interest Payment Period; Notice of
         Extension. (a) At any time following October 1, 2004, if the Company
         shall have paid on September 30, 2004 all interest accrued with respect
         to the Securities as of such date, the Company shall have the right,
         from time to time, to defer payments of interest by extending for
         successive periods not exceeding 20 consecutive quarters for each such
         period (an "Extended Interest Payment Period") but in no event shall
         the Extended Interest Payment Period extend beyond the Maturity of the
         Securities. To the extent permitted by applicable law, interest, the
         payment of which has been deferred because of the extension of the
         interest payment period pursuant to this Section 3.12, will bear
         interest thereon at 7.16% compounded quarterly for each quarter of the
         Extended Interest Payment Period ("Compounded Interest"). At the end of
         the Extended Interest Payment Period, the Company shall pay all
         interest then accrued and unpaid on the Securities, including any
         Compounded Interest that shall be payable to the Holders of the
         Securities in whose names the Securities are registered in the Security
         Register on the first Regular Record Date after the end of the Extended
         Interest Payment Period. Before the termination of any Extended
         Interest Payment Period, the Company may further extend such period,
         provided that such period together with all such further extensions
         thereof shall not exceed 20 consecutive quarters or extend beyond the
         Maturity of the Securities. Upon the termination of any Extended
         Interest Payment Period and upon the payment of all interest then
         accrued and unpaid on the Securities, including any Additional Payments
         then due, the Company may commence a new Extended Interest Payment
         Period, subject to the foregoing requirements. No interest shall be due
         and payable during an Extended Interest Payment Period except at the
         end thereof. In the event the Company fails to pay the interest payment
         due on September 30, 2004, the Company shall permanently forego its
         right to utilize any Extended Interest Payment Periods."

SECTION 4.4. Effective as of the Effective Time, Section 13.01 of the Original
Indenture is hereby amended and restated in its entirety to read as follows:

                  "Section 13.01. Conversion Rights. Subject to and upon
         compliance with the provisions of this Article, the Securities are
         convertible, at the option of the Holder, at any time on or before
         redemption as provided below or the close of business at their Stated
         Maturity, into fully paid and nonassessable shares of Common Stock of
         the Company at an initial conversion rate of 3.5714 shares of Common
         Stock for each $50 in aggregate principal amount of Securities (equal
         to a conversion price of $14.00 per share of Common Stock), subject to
         adjustment as described in this Article XIII. A Holder of Securities
         may convert any portion of the principal amount of the Securities into
         that number of fully paid and nonassessable shares of Common Stock
         (calculated as to each conversion to the nearest 1/100th of a share)
         obtained by dividing the principal amount of the Securities to be
         converted

                                       5
<PAGE>

         by such conversion price. In case a Security or portion thereof is
         called for redemption, such conversion right in respect of this
         Security or portion so called shall expire at the close of business on
         the corresponding Redemption Date, unless the Company defaults in
         making the payment due upon redemption."

         SECTION 4.5. Effective as of the Effective Time, Exhibit A-1 and
Exhibit A-2 of the Original Indenture shall be amended and restated in their
entirety in the form of Exhibit A-1 and Exhibit A-2 attached hereto.

         SECTION 5. MISCELLANEOUS

         SECTION 5.1. EXECUTION AS SUPPLEMENTAL INDENTURE. This First
Supplemental Indenture is executed and shall be construed as an indenture

                               DT INDUSTRIES, INC.

                      7.16% Convertible Junior Subordinated
                    Deferrable Interest Debenture Due 2008(3)

         1. Interest. DT Industries, Inc., a Delaware corporation (the
"Company"), is the issuer of this 7.16% Convertible Junior Subordinated
Deferrable Interest Debenture Due 2008 (the "Security") limited in aggregate
principal amount to $37,165,000 issued under the Indenture hereinafter referred
to. The Company promises to pay interest on the Security in cash from July 3,
2004 or from the most recent subsequent interest payment date to which interest
has been paid or duly provided for, quarterly (subject to deferral for up to 20
consecutive quarters as described in Section 3 hereof) in arrears on March 31,
June 30, September 30 and December 31 of each year (each such date, an "Interest
Payment Date"), commencing September 30, 2004, at the rate of 7.16% per annum
(subject to increase as provided in Section 13 hereto) plus Additional Interest,
if any, until the principal hereof shall have become due and payable.

         The amount of interest payable for any period will be computed on the
basis of twelve 30-day months and a 360-day year. To the extent lawful, the
Company shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue installments of interest (without regard to
any applicable grace period) at the rate borne by the Security, compounded
quarterly. Any interest paid on this Security shall be increased to the extent
necessary to pay Additional Interest as set forth in this Security.

         2. Additional Interest. The Company shall pay to DT Capital Trust (and
its permitted successors or assigns under the Declaration) (the "Trust") such
additional amounts as may be necessary in order that the amount of dividends or
other distributions then due and payable by the Trust on the Preferred
Securities that at any time remain outstanding in accordance with the terms
thereof shall not be reduced as a result of any additional taxes, duties and
other governmental charges of whatever nature (other than withholding taxes)
imposed by the United States or any other taxing authority.

         3. Extension of Interest Payment Period. At any time following October
1, 2004, if the Company shall have paid on September 30, 2004 all interest
accrued with respect to the Security as of such date, the Company shall have the
right from time to time to defer payments of interest by extending the interest
payment period of such Security for up to 20 consecutive quarters (an "Extended
Interest Payment Period"), provided that such Extended Interest Payment Period
shall not extend beyond the Maturity of the Security. To the extent permitted by
applicable law, interest, the payment of which has been deferred because of the
extension of the interest payment period pursuant to Section 3.12 of the
Indenture, will bear interest thereon at

-------
(3)  All terms used in this Security which are defined in the Indenture or in
     the Declaration referred to therein shall have the meanings assigned to
     them in the Indenture or the Declaration, as the case may be.

                                     A-1-4
<PAGE>

7.16% compounded quarterly for each quarter of the Extended Interest Payment
Period ("Compounded Interest"). At the end of the Extended Interest Payment
Period, the Company shall pay all interest then accrued and unpaid on the
Security, including any Compounded Interest that shall be payable to the Holders
of the Security in whose names the Security are registered in the Security
Register on the first Regular Record Date after the end of the Extended Interest
Payment Period. Before the termination of any Extended Interest Payment Period,
the Company may further extend such period, provided that such period together
with all such further extensions thereof shall not exceed 20 consecutive
quarters or extend beyond the Maturity of the Security. Upon the termination of
any Extended Interest Payment Period and upon the payment of all Compounded
Interest and Additional Interest, if any, then due, the Company may commence a
new Extended Interest Payment Period, subject to the foregoing requirements. No
interest shall be due and payable during an Extended Interest Payment Period
except at the end thereof. In the event the Company fails to pay the interest
payment due on September 30, 2004, the Company shall permanently forego its
right to utilize any Extended Interest Payment Period.

         If the Property Trustee is the sole holder of the Security, the Company
shall give the Holder of this Security and the Trustee notice of its selection
of an Extended Interest Payment Period at least one Business Day prior to the
earlier of (i) the Interest Payment Date or (ii) if the Preferred Securities are
listed on the New York Stock Exchange or other stock exchange or quotation
system, the date the Trust is required to give notice to the New York Stock
Exchange or other applicable self-regulatory organization or to holders of the
Preferred Securities on the record date or the date such distributions are
payable, but in any event not less than ten Business Days prior to such record
date.

         If the Property Trustee is not the sole holder of the Security, the
Company shall give the Holders of the Security and the Trustee notice of its
selection of an Extended Interest Payment Period at least ten Business Days
prior to the earlier of (i) the Interest Payment Date or (ii) if the Preferred
Securities are listed on the New York Stock Exchange or other stock exchange or
quotation system, the date the Trust is required to give notice to the New York
Stock Exchange or other applicable self-regulatory organization or to holders of
the Security on the record date or the date such distributions are payable, but
in any event not less than two Business Days prior to such record date.

         The quarter in which any notice is given pursuant to the second and
third paragraphs of this Section 3 shall be counted as one of the 20 quarters
permitted in the maximum Extended Interest Payment Period permitted under the
first paragraph of this Section 3.

         4. Method of Payment. The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the regular
record date for such interest installment, which shall be the close of business
on the day immediately preceding each Interest Payment Date (the "Regular Record
Date"), commencing September 29, 2004. Any such interest not so punctually paid
or duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and

                                     A-1-5
<PAGE>

may either be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities not less than
ten days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange
on which the Securities may be listed, and upon such notice as may be required
by such exchange, all as more fully provided in said Indenture.

         Payment of the principal of and interest on this Security will be made
at the office or agency of the Company maintained for that purpose in New York,
New York, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that, at the option of the Company, payment of interest may
be made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.

         5. Paying Agent and Security Registrar. The Trustee will act as Paying
Agent, Security Registrar and Conversion Agent. The Company may change any
Paying Agent, Security Registrar, co-registrar or Conversion Agent without prior
notice. The Company or any of its Affiliates may act in any such capacity.

         6. Indenture. The Company issued the Securities under an indenture,
dated as of June 1, 1997, as supplemented from time to time (the "Indenture"),
between the Company and The Bank of New York, as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Securities, and of the terms upon which the Securities are, and are to be,
authenticated and delivered. The terms of the Securities include those stated in
the Indenture and those made part of the Indenture by the Trust Indenture Act of
1939 (15 U.S. Code ss.ss. 77aaa-77bbbb) ("TIA") as in effect on the date of the
Indenture. The Securities are subject to, and qualified by, all such terms,
certain of which are summarized hereon, and holders are referred to the
Indenture and the TIA for a statement of such terms. The Securities are
unsecured general obligations of the Company limited to $37,165,000 in aggregate
principal amount and subordinated in right of payment to all existing and future
Senior Indebtedness of the Company. No reference herein to the Indenture and no
provision of this Security or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Security at the times, place and rate, and in
the coin or currency, herein prescribed or to convert this Security as provided
in the Indenture.

         7. Optional Redemption. The Securities are redeemable at the Company's
option at any time and from time to time after June 1, 2000, upon not less than
30 or more than 60 days' notice, at the following prices per $50 principal
amount of the Securities plus any accrued and unpaid interest, including
Additional Interest, if any, to the Redemption Date, if redeemed during the

and thereafter at $50 per $50 principal amount of the Securities plus, in each
case, accrued and unpaid interest, including Additional Interest, if any, to the
Redemption Date (subject to the right of holders of record on the relevant
record date to receive interest due on the Interest Payment Date). On or after
the Redemption Date, interest will cease to accrue on the Securities, or portion
thereof, called for redemption.

         8. Optional Redemption Upon Tax Event. The Securities are subject to
redemption in whole, but not in part, at any time within 90 days, if a Tax Event
(as defined in the Declaration) shall occur and be continuing, at a redemption
price equal to $50 per $50 principal amount thereof plus accrued but unpaid
interest, including Additional Interest, if any, to the Redemption Date. Any
redemption pursuant to this Section 8 will be made upon not less than 30 or more
than 60 days' notice.

         9. Notice of Redemption. Notice of redemption will be mailed at least
30 days but not more than 60 days before the Redemption Date to each Holder of
the Securities to be redeemed at his address of record. The Securities in
denominations larger than $50 may be redeemed in part but only in integral
multiples of $50. In the event of a redemption of less than all of the
Securities, the Securities will be chosen for redemption by the Trustee in
accordance with the Indenture. On and after the Redemption Date, interest ceases
to accrue on the Securities or portions of them called for redemption.

         If this Security is redeemed subsequent to a Regular Record Date with
respect to any Interest Payment Date specified above and on or prior to such
Interest Payment Date, then any accrued interest will be paid to the person in
whose name this Security is registered at the close of business on such record
date.

         10. Mandatory Redemption. The Securities will mature on May 31, 2008
and may be redeemed, in whole or in part, at any time after June 1, 2000, or at
any time in certain circumstances upon the occurrence of a Tax Event. Upon the
repayment of the Securities, whether at maturity or upon redemption, the
proceeds from such repayment or payment shall simultaneously be applied to
redeem Trust Securities (provided Trust Securities remain

                                     A-1-7
<PAGE>

outstanding) having an aggregate liquidation amount of the Securities so repaid
or redeemed at the applicable redemption price together with accrued and unpaid
distributions through the date of redemption; provided, that holders of the
Trust Securities shall be given not less than 30 nor more than 60 days notice of
such redemption. Upon the repayment of the Securities at maturity or upon any
acceleration, earlier redemption or otherwise, the proceeds from such repayment
will be applied to redeem the Preferred Securities, in whole, upon not less than
30 nor more than 60 days' notice. There are no sinking fund payments with
respect to the Securities.

         11. Subordination. The payment of the principal of, interest on or any
other amounts due on the Securities is subordinated in right of payment to all
existing and future Senior Indebtedness (as defined below) of the Company, as
described in the Indenture. Each holder, by accepting a Security, agrees to such
subordination and authorizes and directs the Trustee on its behalf to take such
action as may be necessary or appropriate to effectuate the subordination so
provided and appoints the Trustee as its attorney-in-fact for such purpose.

         Senior Indebtedness shall mean in respect of the Company (i) the
principal, premium, if any, and interest in respect of (A) indebtedness of such
obligor for money borrowed and (B) indebtedness evidenced by securities,
debentures, bonds or other similar instruments issued by such obligor, (ii) all
capital lease obligations of such obligor, (iii) all obligations of such obligor
issued or assumed as the deferred purchase price of property, all conditional
sale obligations of such obligor and all obligations of such obligor under any
title retention agreement (but excluding trade accounts payable arising in the
ordinary course of business), (iv) all obligations of such obligor for the
reimbursement of any letter of credit, banker's acceptance, security purchase
facility or similar credit transaction, (v) all obligations of the type referred
to in clauses (i) through (iv) above of other persons for the payment of which
such obligor is responsible or liable as obligor, guarantor or otherwise, (vi)
all obligations of the type referred to in clauses (i) through (v) above of
other persons secured by any lien on any property or asset of such obligor
(whether or not such obligation is assumed by such obligor), except for (1) any
such indebtedness that is by its terms subordinated to or pari passu with the
Securities and (2) any indebtedness (including all other debt securities and
guarantees in respect of those debt securities) initially issued to any other
trust, or a trustee of such trust, partnership, or other entity affiliated with
the Company that is, directly or indirectly, a financing vehicle of the Company
(a "Financing Entity") in connection with the issuance by such Financing Entity
of preferred securities or other similar securities and (vii) interest accruing
subsequent to events of bankruptcy of the Company and its subsidiaries at the
rate provided for in the documentation governing such Senior Indebtedness,
whether or not such interest is an allowed claim enforceable against the debtor
in a bankruptcy case under relevant bankruptcy law.

    12. Conversion. The Holder of any Security has the right, exercisable at
any time prior to the close of business (New York time) on the date of this
Security's maturity, to convert the principal amount thereof (or any portion
thereof that is an integral multiple of $50) into shares of Common Stock at the
initial conversion rate of 3.5714 shares of Common Stock for each Security
(equivalent to a conversion price of $14.00 per share of Common Stock of the
Company), subject to adjustment under certain circumstances, except that if a
Security is called

                                     A-1-8
<PAGE>

for redemption, the conversion right will terminate at the close of business on
the Redemption Date.

         To convert a Security, a Holder must (1) complete and sign a conversion
notice substantially in the form attached hereto, (2) surrender this Security to
a Conversion Agent, (3) furnish appropriate endorsements or transfer documents
if required by this Security Registrar or Conversion Agent and (4) pay any
transfer or similar tax, if required. Upon conversion, no adjustment or payment
will be made for interest or dividends, but if any Holder surrenders a Security
for conversion after the close of business on the Regular Record Date for the
payment of an installment of interest and prior to the opening of business on
the next Interest Payment Date, then, notwithstanding such conversion, the
interest payable on such Interest Payment Date will be paid to the registered
Holder of such Security on such Regular Record Date. In such event, such
Security, when surrendered for conversion, need not be accompanied by payment of
an amount equal to the interest payable on such Interest Payment Date on the
portion so converted. The number of shares issuable upon conversion of a
Security is determined by dividing the principal amount of this Security
converted by the conversion price in effect on the Conversion Date. No
fractional shares will be issued upon conversion but a cash adjustment will be
made for any fractional interest. The outstanding principal amount of any
Security shall be reduced by the portion of the principal amount thereof
converted into shares of Common Stock.

   13. Registration, Transfer, Exchange and Denominations. As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of
this Security is registrable in the Security Register, upon surrender of this
Security for registration of transfer at the office or agency of the Company in
New York, New York, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

         The Securities are issuable only in registered form without coupons in
denominations of $50 and integral multiples thereof. No service charge shall be
made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. Prior to due presentment of this
Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary. In the event of redemption or conversion of
this Security in part only, a new Security or Securities for the unredeemed or
unconverted portion hereof will be issued in the name of the Holder hereof upon
the cancellation hereof.

         14. Persons Deemed Owners. Except as provided in Section 3 hereof, the
registered Holder of a Security may be treated as its owner for all purposes.

                                     A-1-9
<PAGE>

         15. Unclaimed Money. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, holders of
Securities entitled to the money must look to the Company for payment unless an
abandoned property law designates another Person and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

         16. Defaults and Remedies. The Securities shall have the Events of
Default as set forth in Section 5.01 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the holders of at least 25% in aggregate
principal amount of the then outstanding Securities by notice to the Company and
the Trustee may declare all the Securities to be due and payable immediately;
provided that, if the Property Trustee is the sole Holder of this Security and
if upon an Event of Default, the Trustee or the holder or holders of not less
than 25% in aggregate principal amount of the then outstanding Securities fail
to declare the principal of all the Securities to be immediately due and
payable, the holders of at least 25% in aggregate liquidation amount of
Preferred Securities then outstanding shall have such right by a notice in
writing to the Company and the Trustee; and upon any such declaration such
principal and all accrued interest shall become immediately due and payable;
provided that the payment of principal and interest on such Securities shall
remain subordinated to the extent provided in the Indenture.

         The holders of a majority in principal amount of the Securities then
outstanding by written notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration. Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. Subject to certain limitations, holders of a majority
in principal amount of the then outstanding Securities issued under the
Indenture may direct the Trustee in its exercise of any trust or power. The
Company must furnish annually compliance certificates to the Trustee. The above
description of Events of Default and remedies is qualified by reference to, and
subject in its entirety by, the more complete description thereof contained in
the Indenture.

         17. Amendments, Supplements and Waivers. The Indenture permits, subject
to the rights of the holders of Preferred Securities set forth therein and in
the Declaration and with certain other exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, subject to the
right of the holders of the Preferred Securities set forth therein and in the
Declaration, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made

                                     A-1-10
<PAGE>

upon this Security. The above description of amendments, supplements and
waivers is qualified by reference to, and subject in its entirety by the more
complete description thereof contained in the Indenture.

         18. Trustee Dealings with the Company. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Securities and may
otherwise deal with the Company or an Affiliate with the same rights it would
have, as if it were not Trustee, subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

         19. No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Securities by accepting a Security waives and
releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

         20. Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE SECURITIES WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.

         21. Authentication. The Securities shall not be valid until
authenticated by the manual signature of an authorized signatory of the Trustee
or an authenticating agent.

         22. Abbreviations. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

         The Company will furnish to any Holder of the Securities upon written
request and without charge a copy of the Indenture. Request may be made to:

                               DT INDUSTRIES, INC.

                      7.16% CONVERTIBLE JUNIOR SUBORDINATED
                   DEFERRABLE INTEREST DEBENTURE DUE 2008(9)

         1. Interest. DT Industries, Inc., a Delaware corporation (the
"Company"), is the issuer of this 7.16% Convertible Junior Subordinated
Deferrable Interest Debenture Due 2008 (the "Security") limited in aggregate
principal amount to $37,165,000 issued under the Indenture hereinafter referred
to. The Company promises to pay interest on the Security in cash from July 3,
2004 or from the most recent subsequent interest payment date to which interest
has been paid or duly provided for, quarterly (subject to deferral for up to 20
consecutive quarters as described in Section 3 hereof) in arrears on March 31,
June 30, September 30 and December 31 of each year (each such date, an "Interest
Payment Date"), commencing September 30, 2004, at the rate of 7.16% per annum
(subject to increase as provided in Section 13 hereto) plus Additional Interest,
if any, until the principal hereof shall have become due and payable.

         The amount of interest payable for any period will be computed on the
basis of twelve 30-day months and a 360-day year. To the extent lawful, the
Company shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue installments of interest (without regard to
any applicable grace period) at the rate borne by the Securities, compounded
quarterly. Any interest paid on this Security shall be increased to the extent
necessary to pay Additional Interest as set forth in this Security.

         2. Additional Interest. The Company shall pay to DT Capital Trust (and
its permitted successors or assigns under the Declaration) (the "Trust") such
additional amounts as may be necessary in order that the amount of dividends or
other distributions then due and payable by the Trust on the Preferred
Securities that at any time remain outstanding in accordance with the terms
thereof shall not be reduced as a result of any additional taxes, duties and
other governmental charges of whatever nature (other than withholding taxes)
imposed by the United States or any other taxing authority.

         3. Extension of Interest Payment Period. At any time following October
1, 2004, if the Company shall have paid on September 30, 2004 all interest
accrued with respect to the Security as of such date, the Company shall have the
right, from time to time to defer payments of interest by extending the interest
payment period of such Security for up to 20 consecutive quarters (an "Extended
Interest Payment Period"), provided that such Extended Interest Payment Period
shall not extend beyond the Maturity of the Security. To the extent permitted by
applicable law, interest, the payment of which has been deferred because of the
extension of the interest payment period pursuant to Section 3.12 of the
Indenture, will bear interest thereon at 7.16% compounded quarterly for each
quarter of the Extended Interest Payment Period ("Compounded Interest"). At

------
(9)  All terms used in this Security which are defined in the Indenture
     or in the Declaration referred to therein shall have the meanings assigned
     to them in the Indenture or the Declaration, as the case may be.

                                     A-2-3
<PAGE>

the end of the Extended Interest Payment Period, the Company shall pay all
interest then accrued and unpaid on the Securities, including any Compounded
Interest that shall be payable to the Holders of the Securities in whose names
the Securities are registered in the Security Register on the first Regular
Record Date after the end of the Extended Interest Payment Period. Before the
termination of any Extended Interest Payment Period, the Company may further
extend such period, provided that such period together with all such further
extensions thereof shall not exceed 20 consecutive quarters or extend beyond the
Maturity of this Security. Upon the termination of any Extended Interest Payment
Period and upon the payment of all Compounded Interest and Additional Interest,
if any, then due, the Company may commence a new Extended Interest Payment
Period, subject to the foregoing requirements. No interest shall be due and
payable during an Extended Interest Payment Period except at the end thereof. In
the event the Company fails to pay the interest payment due on September 30,
2004, the Company shall permanently forego its right to utilize any Extended
Interest Payment Period.

         If the Property Trustee is the sole holder of this Security, the
Company shall give the Holder of this Security and the Trustee notice of its
selection of an Extended Interest Payment Period at least one Business Day prior
to the earlier of (i) the Interest Payment Date or (ii) if the Preferred
Securities are listed on the New York Stock Exchange or other stock exchange or
quotation system, the date the Trust is required to give notice to the New York
Stock Exchange or other applicable self-regulatory organization or to holders of
the Preferred Securities on the record date or the date such distributions are
payable, but in any event not less than ten Business Days prior to such record
date.

         If the Property Trustee is not the sole holder of the Securities, the
Company shall give the Holders of the Securities and the Trustee notice of its
selection of an Extended Interest Payment Period at least ten Business Days
prior to the earlier of (i) the Interest Payment Date or (ii) if the Preferred
Securities are listed on the New York Stock Exchange or other stock exchange or
quotation system, the date the Trust is required to give notice to the New York
Stock Exchange or other applicable self-regulatory organization or to holders of
the Securities on the record date or the date such distributions are payable,
but in any event not less than two Business Days prior to such record date.

         The quarter in which any notice is given pursuant to the second and
third paragraphs of this Section 3 shall be counted as one of the 20 quarters
permitted in the maximum Extended Interest Payment Period permitted under the
first paragraph of this Section 3.

         4. Method of Payment. The interest so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the regular
record date for such interest installment, which shall be the close of business
on the day immediately preceding each Interest Payment Date (the "Regular Record
Date"), commencing September 29, 2004. Any such interest not so punctually paid
or duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of

                                     A-2-4
<PAGE>

such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities not less than ten days prior to such Special
Record Date, or be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in said Indenture.

         Payment of the principal of and interest on this Security will be made
at the office or agency of the Company maintained for that purpose in New York,
New York, in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts;
provided, however, that, at the option of the Company, payment of interest may
be made by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register.

         5. Paying Agent and Security Registrar. The Trustee will act as Paying
Agent, Security Registrar and Conversion Agent. The Company may change any
Paying Agent, Security Registrar, co-registrar or Conversion Agent without prior
notice. The Company or any of its Affiliates may act in any such capacity.

         6. Indenture. The Company issued the Securities under an indenture,
dated as of June 1, 1997, as supplemented from time to time (the "Indenture"),
between the Company and The Bank of New York, as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby made
for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Trustee, the Company and the Holders of the
Securities, and of the terms upon which the Securities are, and are to be,
authenticated and delivered. The terms of the Securities include those stated in
the Indenture and those made part of the Indenture by the Trust Indenture Act of
1939 (15 U.S. Code ss.ss. 77aaa-77bbbb) ("TIA") as in effect on the date of the
Indenture. The Securities are subject to, and qualified by, all such terms,
certain of which are summarized hereon, and holders are referred to the
Indenture and the TIA for a statement of such terms. The Securities are
unsecured general obligations of the Company limited to $37,165,000 in aggregate
principal amount and subordinated in right of payment to all existing and future
Senior Indebtedness of the Company. No reference herein to the indenture and no
provision of this Security or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the
principal of and interest on this Security at the times, place and rate, and in
the coin or currency, herein prescribed or to convert this Security as provided
in the Indenture.

         7. Optional Redemption. The Securities are redeemable at the Company's
option at any time and from time to time after June 1, 2000, upon not less than
30 or more than 60 days' notice, at the following prices per $50 principal
amount of the Securities plus any accrued and unpaid interest, including
Additional Interest, if any, to the Redemption Date, if redeemed during the
12-month period ending June 1:

<PAGE>

                                           Price Per $50
              Year                       Principal Amount
       ---------------------             ---------------

2001................................          $52.51
2002................................           52.15
2003................................           51.79
2004................................           51.43
2005................................           51.07
2006 ...............................           50.72
2007................................           50.36

and thereafter at $50 per $50 principal amount of the Securities plus, in each
case, accrued and unpaid interest, including Additional Interest, if any, to the
Redemption Date (subject to the right of holders of record on the relevant
record date to receive interest due on the Interest Payment Date). On or after
the Redemption Date, interest will cease to accrue on the Securities, or portion
thereof, called for redemption.

         8. Optional Redemption Upon Tax Event. The Securities are subject to
redemption in whole, but not in part, at any time within 90 days, if a Tax Event
(as defined in the Declaration) shall occur and be continuing, at a redemption
price equal to $50 per $50 principal amount thereof plus accrued but unpaid
interest, including Additional Interest, if any, to the Redemption Date. Any
redemption pursuant to this Section 8 will be made upon not less than 30 nor
more than 60 days' notice.

         9. Notice of Redemption. Notice of redemption will be mailed at least
30 days but not more than 60 days before the Redemption Date to each Holder of
the Securities to be redeemed at his address of record. The Securities in
denominations larger than $50 may be redeemed in part but only in integral
multiples of $50. In the event of a redemption of less than all of the
Securities, the Securities will be chosen for redemption by the Trustee in
accordance with the Indenture. On and after the Redemption Date, interest ceases
to accrue on the Securities or portions of them called for redemption.

         If this Security is redeemed subsequent to a Regular Record Date with
respect to any Interest Payment Date specified above and on or prior to such
Interest Payment Date, then any accrued interest will be paid to the person in
whose name this Security is registered at the close of business on such record
date.

         10. Mandatory Redemption. The Securities will mature on May 31, 2008
and may be redeemed, in whole or in part, at any time after June 1, 2000, or at
any time in certain circumstances upon the occurrence of a Tax Event. Upon the
repayment of the Securities, whether at maturity or upon redemption, the
proceeds from such repayment or payment shall simultaneously be applied to
redeem Trust Securities (provided that Trust Securities remain

                                     A-2-6
<PAGE>

outstanding) having an aggregate liquidation amount of the Securities so repaid
or redeemed at the applicable redemption price together with accrued and unpaid
distributions through the date of redemption; provided, that holders of the
Trust Securities shall be given not less than 30 nor more than 60 days notice of
such redemption. Upon the repayment of the Securities at maturity or upon any
acceleration, earlier redemption or otherwise, the proceeds from such repayment
will be applied to redeem the Preferred Securities, in whole, upon not less than
30 nor more than 60 days' notice. There are no sinking fund payments with
respect to the Securities.

         11. Subordination. The payment of the principal of, interest on or any
other amounts due on the Securities is subordinated in right of payment to all
existing and future Senior Indebtedness (as defined below) of the Company, as
described in the Indenture. Each holder, by accepting a Security, agrees to such
subordination and authorizes and directs the Trustee on its behalf to take such
action as may be necessary or appropriate to effectuate the subordination so
provided and appoints the Trustee as its attorney-in-fact for such purpose.

         Senior Indebtedness shall mean in respect of the Company (i) the
principal, premium, if any, and interest in respect of (A) indebtedness of such
obligor for money borrowed and (B) indebtedness evidenced by securities,
debentures, bonds or other similar instruments issued by such obligor, (ii) all
capital lease obligations of such obligor, (iii) all obligations of such obligor
issued or assumed as the deferred purchase price of property, all conditional
sale obligations of such obligor and all obligations of such obligor under any
title retention agreement (but excluding trade accounts payable arising in the
ordinary course of business), (iv) all obligations of such obligor for the
reimbursement of any letter of credit, banker's acceptance, security purchase
facility or similar credit transaction, (v) all obligations of the type referred
to in clauses (i) through (iv) above of other persons for the payment of which
such obligor is responsible or liable as obligor, guarantor or otherwise, (vi)
all obligations of the type referred to in clauses (i) through (v) above of
other persons secured by any lien on any property or asset of such obligor
(whether or not such obligation is assumed by such obligor), except for (1) any
such indebtedness that is by its terms subordinated to or pari passu with the
Securities and (2) any indebtedness (including all other debt securities and
guarantees in respect of those debt securities) initially issued to any other
trust, or a trustee of such trust, partnership, or other entity affiliated with
the Company that is, directly or indirectly, a financing vehicle of the Company
(a "Financing Entity") in connection with the issuance by such Financing Entity
of preferred securities or other similar securities and (vii) interest accruing
subsequent to events of bankruptcy of the Company and its subsidiaries at the
rate provided for in the documentation governing such Senior Indebtedness,
whether or not such interest is an allowed claim enforceable against the debtor
in a bankruptcy case under relevant bankruptcy law.

         12. Conversion. The Holder of any Security has the right, exercisable
at any time prior to the close of business (New York time) on the date of this
Security's maturity, to convert the principal amount thereof (or any portion
thereof that is an integral multiple of $50) into shares of Common Stock at the
initial conversion rate of 3.5714 shares of Common Stock for each Security
(equivalent to a conversion price of $14.00 per share of Common Stock of the
Company), subject to adjustment under certain circumstances, except that if a
Security is called

                                     A-2-7
<PAGE>

for redemption, the conversion right will terminate at the close of business on
the Redemption Date.

         To convert a Security, a Holder must (1) complete and sign a conversion
notice substantially in the form attached hereto, (2) surrender this Security to
a Conversion Agent, (3) furnish appropriate endorsements or transfer documents
if required by the Security Registrar or Conversion Agent and (4) pay any
transfer or similar tax, if required. Upon conversion, no adjustment or payment
will be made for interest or dividends, but if any Holder surrenders a Security
for conversion after the close of business on the Regular Record Date for the
payment of an installment of interest and prior to the opening of business on
the next Interest Payment Date, then, notwithstanding such conversion, the
interest payable on such Interest Payment Date will be paid to the registered
Holder of such Security on such Regular Record Date. In such event, such
Security, when surrendered for conversion, need not be accompanied by payment of
an amount equal to the interest payable on such Interest Payment Date on the
portion so converted. The number of shares issuable upon conversion of a
Security is determined by dividing the principal amount of this Security
converted by the conversion price in effect on the Conversion Date. No
fractional shares will be issued upon conversion but a cash adjustment will be
made for any fractional interest. The outstanding principal amount of any
Security shall be reduced by the portion of the principal amount thereof
converted into shares of Common Stock.

         13. Registration, Transfer, Exchange and Denominations. As provided in
the Indenture and subject to certain limitations therein set forth, the transfer
of this Security is registrable in the Security Register, upon surrender of this
Security for registration of transfer at the office or agency of the Company in
New York, New York, duly endorsed by, or accompanied by a written instrument of
transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Securities, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

         The Securities are issuable only in registered form without coupons in
denominations of $50 and integral multiples thereof. No service charge shall be
made for any such registration of transfer or exchange, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge payable in connection therewith. Prior to due presentment of this
Security for registration of transfer, the Company, the Trustee and any agent of
the Company or the Trustee may treat the Person in whose name this Security is
registered as the owner hereof for all purposes, whether or not this Security be
overdue, and neither the Company, the Trustee nor any such agent shall be
affected by notice to the contrary. In the event of redemption or conversion of
this Security in part only, a new Security or Securities for the unredeemed or
unconverted portion hereof will be issued in the name of the Holder hereof upon
the cancellation hereof.

         14. Persons Deemed Owners. Except as provided in Section 3 hereof, the
registered Holder of a Security may be treated as its owner for all purposes.

                                     A-2-8
<PAGE>

         15. Unclaimed Money. If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request. After that, holders of
Securities entitled to the money must look to the Company for payment unless an
abandoned property law designates another Person and all liability of the
Trustee and such Paying Agent with respect to such money shall cease.

         16. Defaults and Remedies. The Securities shall have the Events of
Default as set forth in Section 5.01 of the Indenture. Subject to certain
limitations in the Indenture, if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the holders of at least 25% in aggregate
principal amount of the then outstanding Securities by notice to the Company and
the Trustee may declare all the Securities to be due and payable immediately;
provided that, if the Property Trustee is the sole Holder of this Security and
if upon an Event of Default, the Trustee or the holder or holders of not less
than 25% in aggregate principal amount of the then outstanding Securities fail
to declare the principal of all the Securities to be immediately due and
payable, the holders of at least 25% in aggregate liquidation amount of
Preferred Securities then outstanding shall have such right by a notice in
writing to the Company and the Trustee; and upon any such declaration such
principal and all accrued interest shall become immediately due and payable;
provided that the payment of principal and interest on such Securities shall
remain subordinated to the extent provided in the Indenture.

         The holders of a majority in principal amount of the Securities then
outstanding by written notice to the Trustee may rescind an acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default have been cured or waived except
nonpayment of principal or interest that has become due solely because of the
acceleration. Holders may not enforce the Indenture or the Securities except as
provided in the Indenture. Subject to certain limitations, holders of a majority
in principal amount of the then outstanding Securities issued under the
Indenture may direct the Trustee in its exercise of any trust or power. The
Company must furnish annually compliance certificates to the Trustee. The above
description of Events of Default and remedies is qualified by reference to, and
subject in its entirety by, the more complete description thereof contained in
the Indenture.

         17. Amendments, Supplements and Waivers. The Indenture permits, subject
to the rights of the holders of Preferred Securities set forth therein and in
the Declaration and with certain other exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities at the time
Outstanding. The Indenture also contains provisions permitting the Holders of
specified percentages in aggregate principal amount of the Securities at the
time Outstanding, on behalf of the Holders of all the Securities, subject to the
right of the holders of the Preferred Securities set forth therein and in the
Declaration, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and of
any Security issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made

                                     A-2-9
<PAGE>

upon this Security. The above description of amendments, supplements and
waivers is qualified by reference to, and subject in its entirety by the more
complete description thereof contained in the Indenture.

         18. Trustee Dealings with the Company. The Trustee, in its individual
or any other capacity may become the owner or pledgee of the Securities and may
otherwise deal with the Company or an Affiliate with the same rights it would
have, as if it were not Trustee, subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

         19. No Recourse Against Others. A director, officer, employee or
stockholder, as such, of the Company shall not have any liability for any
obligations of the Company under the Securities or the Indenture or for any
claim based on, in respect of or by reason of such obligations or their
creation. Each Holder of the Securities by accepting a Security waives and
releases all such liability. The waiver and release are part of the
consideration for the issue of the Securities.

         20. Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL
GOVERN THE INDENTURE AND THE SECURITIES WITHOUT REGARD TO CONFLICT OF LAW
PROVISIONS THEREOF.

         21. Authentication. The Securities shall not be valid until
authenticated by the manual signature of an authorized signatory of the Trustee
or an authenticating agent.

         22. Abbreviations. Customary abbreviations may be used in the name of a
