            SECTION 2. SHELF REGISTRATION. (a) The Company shall use its best
efforts to prepare and file or cause to be prepared and filed with the SEC, as
soon as practicable but in any event by the date (the "FILING DEADLINE DATE")
ninety (90) days after the Issue Date, a Registration Statement for an offering
to be made on a delayed or continuous basis pursuant to Rule 415 of the
Securities Act (a "SHELF REGISTRATION STATEMENT") registering the resale from
time to time by Holders thereof of all of the Registrable Securities (the
"INITIAL SHELF REGISTRATION STATEMENT"). The Initial Shelf Registration
Statement shall be on Form S-3 or another appropriate form permitting
registration of such Registrable Securities for resale by such Holders in
accordance with the methods of distribution elected by the Holders and set forth
in the Initial Shelf Registration Statement. The Company shall use its
reasonable efforts to cause the Initial Shelf Registration Statement to be
declared effective under the Securities Act as promptly as is practicable but in
any event by the date (the "EFFECTIVENESS DEADLINE DATE") that is one hundred
eighty (180) days after the Issue Date, and to keep the Initial Shelf
Registration Statement (or any Subsequent Shelf Registration Statement)
continuously effective under the Securities Act until the expiration of the
Effectiveness Period. At the time the Initial Shelf Registration Statement is
declared effective, each Holder that became a Notice Holder on or prior to the
date ten (10) Business Days prior to such time of effectiveness shall be named
as a selling securityholder in the Initial Shelf Registration Statement and the
related Prospectus in such a manner as to permit such Holder to deliver such
Prospectus to purchasers of Registrable Securities in accordance with applicable
law. None of the Company's security holders (other than the Holders of
Registrable Securities) shall have the right to include any of the Company's
securities in the Shelf Registration Statement.

            (a) (placeholder do not delete)

            (b) If the Initial Shelf Registration Statement or any Subsequent
Shelf Registration Statement ceases to be effective for any reason at any time
during the Effectiveness Period (other than because all Registrable Securities
registered thereunder shall have been resold pursuant thereto or shall have
otherwise ceased to be Registrable Securities), the Company shall use its
reasonable efforts to obtain the prompt withdrawal of any order suspending the
effectiveness thereof, and in any event shall within thirty (30) days of such
cessation of effectiveness amend the Shelf Registration Statement in a manner
reasonably expected to obtain the withdrawal of the order suspending the
effectiveness thereof, or file an additional Shelf Registration Statement
covering all of the securities that as of the date of such filing are
Registrable Securities (a "SUBSEQUENT SHELF REGISTRATION STATEMENT"). If a
Subsequent Shelf Registration Statement is filed, the Company shall use its
reasonable efforts to cause the Subsequent Shelf Registration Statement to
become effective as promptly as is practicable after such filing and to keep
such Shelf Registration Statement (or subsequent Shelf Registration Statement)
continuously effective until the end of the Effectiveness Period.

            (c) The Company shall supplement and amend the Shelf Registration
Statement if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Shelf Registration Statement,
if required by the Securities Act or as reasonably requested by the Initial
Purchasers or by the Trustee on behalf of the Holders of the Registrable
Securities covered by such Shelf Registration Statement.

            (d) Each Holder of Registrable Securities agrees that if such Holder
wishes to sell Registrable Securities pursuant to a Shelf Registration Statement
and related Prospectus, it will do so only in accordance with this Section 2(d)
and Section 3(i). Each Holder of Registrable Securities wishing to sell
Registrable Securities pursuant to a Shelf Registration Statement and related
Prospectus agrees to deliver a Notice and Questionnaire to the Company at least
three (3) Business Days prior to any intended distribution of Registrable
Securities under the Shelf Registration Statement. From and after the date the
Initial Shelf Registration Statement is declared effective, the Company shall,
as promptly as practicable after the date a Notice and Questionnaire is received
by the Company, and in any event upon the later of (x) five (5) Business Days
after such date or (y) five (5) Business Days after the expiration of any
Deferral Period in effect when the Notice and Questionnaire is delivered or put
into effect within five (5) Business Days of such delivery date, (i) if required
by applicable law, file with the SEC a post-effective amendment to the Shelf
Registration Statement or prepare and, if required by applicable law, file a
supplement to the related Prospectus or a supplement or amendment to any
document incorporated therein by reference or file any other required document
so that the Holder delivering such Notice and Questionnaire is named as a
selling securityholder in the Shelf Registration Statement and the related
Prospectus in such a manner as to permit such Holder to deliver such Prospectus
to purchasers of the Registrable Securities in accordance with applicable law
and, if the Company shall file a post-effective amendment to the Shelf
Registration Statement, use its reasonable efforts to cause such post-effective
amendment to be declared effective under the Securities Act as promptly as is
practicable, but in any event by the date (the "AMENDMENT EFFECTIVENESS DEADLINE
DATE") that is sixty (60) days after the date such post-effective amendment is
required by this clause to be filed; (ii) provide such Holder copies of any
documents filed pursuant to Section 2(d)(i); and (iii) notify such Holder as
promptly as practicable after the effectiveness under the Securities Act of any
post-effective amendment filed pursuant to Section 2(d)(i); provided, that if
such Notice and Questionnaire is delivered during a Deferral Period, the Company
shall so inform the Holder delivering such Notice and Questionnaire and shall
take the actions set forth in clauses (i), (ii) and (iii) above upon expiration
of the Deferral Period in accordance with Section 3(i). Notwithstanding anything
contained herein to the contrary, (i) the Company shall be under no obligation
to name any Holder that is not a Notice Holder as a selling securityholder in
any Registration Statement or related Prospectus and (ii) the Amendment
Effectiveness Deadline Date shall be extended by up to ten (10) Business Days
from the expiration of a Deferral Period (and the Company shall incur no
obligation to pay Liquidated Damages during such extension) if such Deferral
Period shall be in effect on the Amendment Effectiveness Deadline Date.

            (e) The parties hereto agree that the Holders of Registrable
Securities will suffer damages, and that it would not be feasible to ascertain
the extent of such damages with precision, if (i) the Initial Shelf Registration
Statement has not been filed on or prior to the Filing Deadline Date, (ii) the
Initial Shelf Registration Statement has not been declared effective under the
Securities Act on or prior to the Effectiveness Deadline Date, (iii) the Company
has failed to perform its obligations set forth in Section 2(d) within the time
period required therein, (iv) the aggregate duration of Deferral Periods in any
period exceeds the number of days permitted in respect of such period pursuant
to Section 3(i)

                                       6
<PAGE>   8
hereof or (v) the number of Deferral Periods in any period exceeds the number
permitted in respect of such period pursuant to Section 3(i) hereof (each of the
events of a type described in any of the foregoing clauses (i) through (v) are
individually referred to herein as an "EVENT," and the Filing Deadline Date in
the case of clause (i), the Effectiveness Deadline Date in the case of clause
(ii), the date by which the Company is required to perform its obligations set
forth in Section 2(d) in the case of clause (iii) (including the filing of any
post-effective amendment prior to the Amendment Effectiveness Deadline Date),
the date on which the aggregate duration of Deferral Periods in any period
exceeds the number of days permitted by Section 3(i) hereof in the case of
clause (iv), and the date of the commencement of a Deferral Period that causes
the limit on the number of Deferral Periods in any period under Section 3(i)
hereof to be exceeded in the case of clause (v), being referred to herein as an
"EVENT DATE"). Events shall be deemed to continue until the "EVENT TERMINATION
DATE," which shall be the following dates with respect to the respective types
of Events: the date the Initial Shelf Registration Statement is filed in the
case of an Event of the type described in clause (i), the date the Initial Shelf
Registration Statement is declared effective under the Securities Act in the
case of an Event of the type described in clause (ii), the date the Company
performs its obligations set forth in Section 2(d) in the case of an Event of
the type described in clause (iii) (including, without limitation, the date the
relevant post-effective amendment to the Shelf Registration Statement is
declared effective under the Securities Act), termination of the Deferral Period
that caused the limit on the aggregate duration of Deferral Periods in a period
set forth in Section 3(i) to be exceeded in the case of the commencement of an
Event of the type described in clause (iv), and termination of the Deferral
Period the commencement of which caused the number of Deferral Periods in a
period permitted by Section 3(i) to be exceeded in the case of an Event of the
type described in clause (v).

            Accordingly, commencing on (and including) any Event Date and ending
on (but excluding) the next date on which there are no Events that have occurred
and are continuing (a "DAMAGES ACCRUAL PERIOD"), the Company agrees to pay, as
liquidated damages and not as a penalty, an amount (the "LIQUIDATED DAMAGES
AMOUNT"), payable on the Damages Payment Dates to Record Holders of Securities
that are Registrable Securities and of shares of Underlying Securities issued
upon conversion of Securities that are Registrable Securities, as the case may
be, accruing, for each portion of such Damages Accrual Period beginning on and
including a Damages Payment Date (or, in respect of the first time that the
Liquidated Damages Amount is to be paid to Holders on a Damages Payment Date as
a result of the occurrence of any particular Event, from the Event Date) and
ending on but excluding the first to occur of (A) the date of the end of the
Damages Accrual Period or (B) the next Damages Payment Date, at a rate per annum
equal to one-half of one percent (0.5%) of the aggregate principal amount of
such Securities or, in the case of Securities that have been converted into or
exchanged for Underlying Securities, the Applicable Conversion Price of such
shares of Underlying Securities, as the case may be, in each case determined as
of the Business Day immediately preceding the next Damages Payment Date;
provided, that in the case of a Damages Accrual Period that is in effect solely
as a result of an Event of the type described in clause (iii) of the immediately
preceding paragraph, such Liquidated Damages Amount shall be paid only to the
Holders that have delivered Notice and

                                       7
<PAGE>   9
Questionnaires that caused the Company to incur the obligations set forth in
Section 2(d) the non-performance of which is the basis of such Event, provided
further, that any Liquidated Damages Amount accrued with respect to any Security
or portion thereof called for redemption on a redemption date or converted into
Underlying Securities on a conversion date prior to the Damages Payment Date,
shall, in any such event, be paid instead to the Holder who submitted such
Security or portion thereof for redemption or conversion on the applicable
redemption date or conversion date, as the case may be, on such date (or
promptly following the conversion date, in the case of conversion).
Notwithstanding the foregoing, no Liquidated Damages Amounts shall accrue as to
any Registrable Security from and after the earlier of (x) the date such
security is no longer a Registrable Security and (y) expiration of the
Effectiveness Period. The rate of accrual of the Liquidated Damages Amount with
respect to any period shall not exceed the rate provided for in this paragraph
notwithstanding the occurrence of multiple concurrent Events. Following the cure
of all Events requiring the payment by the Company of Liquidated Damages Amounts
to the Holders of Registrable Securities pursuant to this Section, the accrual
of Liquidated Damages Amounts will cease (without in any way limiting the effect
of any subsequent Event requiring the payment of Liquidated Damages Amount by
the Company).

            The Trustee shall be entitled, on behalf of Holders of Securities or
Underlying Securities, to seek any available remedy for the enforcement of this
Agreement, including for the payment of any Liquidated Damages Amount.
Notwithstanding the foregoing, the parties agree that the sole damages payable
for a violation of the terms of this Agreement with respect to which liquidated
damages are expressly provided shall be such liquidated damages. Nothing shall
preclude a Notice Holder or Holder of Registrable Securities from pursuing or
obtaining specific performance or other equitable relief with respect to this
Agreement.

            All of the Company's obligations set forth in this Section 2(e) that
are outstanding with respect to any Registrable Security at the time such
security ceases to be a Registrable Security shall survive until such time as
all such obligations with respect to such security have been satisfied in full
(notwithstanding termination of this Agreement pursuant to Section 8(k)).

            The parties hereto agree that the liquidated damages provided for in
this Section 2(e) constitute a reasonable estimate of the damages that may be
incurred by Holders of Registrable Securities by reason of the failure of the
Shelf Registration Statement to be filed or declared effective or available for
effecting resales of Registrable Securities in accordance with the provisions
hereof.

            SECTION 3. REGISTRATION PROCEDURES. In connection with the
registration obligations of the Company under Section 2 hereof, the Company
shall:

            (a) Prepare and file with the SEC a Registration Statement or

to Rule 424 (or any similar provisions then in force) under the Securities Act;
and use its commercially reasonable efforts to comply with the provisions of the
Securities Act applicable to it with respect to the disposition of all
securities covered by such Registration Statement during the Effectiveness
Period in accordance with the intended methods of disposition by the sellers
thereof set forth in such Registration Statement as so amended or such
Prospectus as so supplemented.

request, following the effectiveness of the Initial Shelf Registration Statement
under the Securities Act, by the SEC or any other federal or state governmental
authority for amendments or supplements to any Registration Statement or related
Prospectus or for additional information, (iii) of the issuance by the SEC or
any other federal or state governmental authority of any stop order suspending
the effectiveness of any Registration Statement or the initiation or threatening
of any proceedings for that purpose, (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the occurrence of (but not the nature of or details concerning)
a Material Event and (vi) of the determination by the Company that a
post-effective amendment to a Registration Statement will be filed with the SEC,
which notice may, at the discretion of the Company (or as required pursuant to
Section 3 (i)), state that it constitutes a Deferral Notice, in which event the
provisions of Section 3(i) shall apply.

            (d) Use reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction in which they have been
qualified for sale, in either case at the earliest possible moment, and provide
prompt notice to each Notice Holder and the Initial Purchasers of the withdrawal
of any such order.

<PAGE>   11
            (e) If reasonably requested by the Initial Purchasers or any Notice
Holder, as promptly as practicable incorporate in a Prospectus supplement or
post-effective amendment to a Registration Statement such information as the
Initial Purchasers, the Special Counsel or such Notice Holder shall, on the
basis of a written opinion of nationally-recognized counsel experienced in such
matters, determine to be required to be included therein by applicable law and
make any required filings of such Prospectus supplement or such post-effective
amendment.

            (f) As promptly as practicable furnish to each Notice Holder, the
Special Counsel and the Initial Purchasers, upon written request, without
charge, at least one (1) conformed copy of the Registration Statement and any
amendment thereto, including financial statements but excluding schedules, all
documents incorporated or deemed to be incorporated therein by reference and all
exhibits (unless requested in writing to the Company by such Notice Holder,
Special Counsel, counsel or Initial Purchasers).

            (g) During the Effectiveness Period, deliver to each Notice Holder,
the Special Counsel and the Initial Purchasers, in connection with any sale of
Registrable Securities pursuant to a Registration Statement, without charge, as
many copies of the Prospectus or Prospectuses relating to such Registrable
Securities (including each preliminary prospectus) and any amendment or
supplement thereto as such Notice Holder may reasonably request; and the Company
hereby consents (except during such periods that a Deferral Notice is
outstanding and has not been revoked) to the use of such Prospectus or each
amendment or supplement thereto by each Notice Holder, in connection with any
offering and sale of the Registrable Securities covered by such Prospectus or
any amendment or supplement thereto in the manner set forth therein.

            (h) Prior to any public offering of the Registrable Securities
pursuant to the Shelf Registration Statement, register or qualify or cooperate
with the Notice Holders in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Notice Holder reasonably requests
in writing (which request may be included in the Notice and Questionnaire);
prior to any public offering of the Registrable Securities pursuant to the Shelf
Registration Statement, keep each such registration or qualification (or
exemption therefrom) effective during the Effectiveness Period in connection
with such Notice Holder's offer and sale of Registrable Securities pursuant to
such registration or qualification (or exemption therefrom) and do any and all
other acts or things reasonably necessary or advisable to enable the disposition
in such jurisdictions of such Registrable Securities in the manner set forth in
the relevant Registration Statement and the related Prospectus; provided, that
the Company will not be required to (i) qualify as a foreign corporation or as a
dealer in securities in any jurisdiction where it would not otherwise be
required to qualify but for this Agreement or (ii) take any action that would
subject it to general service of process in suits or to taxation in any such
jurisdiction where it is not then so subject.

            (i) Upon (A) the issuance by the SEC of a stop order suspending the
effectiveness of the Shelf Registration Statement or the initiation of
proceedings with

                                       10
<PAGE>   12
respect to the Shelf Registration Statement under Section 8(d) or 8(e) of the
Securities Act, (B) the occurrence of any event or the existence of any fact (a
"MATERIAL EVENT") as a result of which any Registration Statement shall contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any Prospectus shall contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, or (C) the occurrence or existence
of any pending corporate development that, in the reasonable discretion of the
Company, makes it appropriate to suspend the availability of the Shelf
Registration Statement and the related Prospectus, (i) in the case of clause (B)
above, subject to the next sentence, as promptly as practicable prepare and
file, if necessary pursuant to applicable law, a post-effective amendment to
such Registration Statement or a supplement to the related Prospectus or any
document incorporated therein by reference or file any other required document
that would be incorporated by reference into such Registration Statement and
Prospectus so that such Registration Statement does not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, and
such Prospectus does not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, as thereafter delivered to the purchasers of the
Registrable Securities being sold thereunder, and, in the case of a
post-effective amendment to a Registration Statement, subject to the next
sentence, use its reasonable efforts to cause it to be declared effective as
promptly as is practicable, and (ii) give notice to the Notice Holders and the
Special Counsel that the availability of the Shelf Registration Statement is
suspended (a "DEFERRAL NOTICE") and, upon receipt of any Deferral Notice, each
Notice Holder agrees not to sell any Registrable Securities pursuant to the
Registration Statement until such Notice Holder's receipt of copies of the
supplemented or amended Prospectus provided for in clause (i) above, or until it
is advised in writing by the Company that the Prospectus may be used, and has
received copies of any additional or supplemental filings that are incorporated
or deemed incorporated by reference in such Prospectus. The Company will use its
commercially reasonable efforts to ensure that the use of the Prospectus may be
resumed (x) in the case of clause (A) above, as promptly as is practicable, (y)
in the case of clause (B) above, as soon as, in the sole judgment of the
Company, public disclosure of such Material Event would not be prejudicial to or
contrary to the interests of the Company or, if necessary to avoid unreasonable
burden or expense, as soon as practicable thereafter and (z) in the case of
clause (C) above, as soon as, in the sole discretion of the Company, such
suspension is no longer appropriate. The Company shall be entitled to exercise
its right under this Section 3(i) to suspend the availability of the Shelf
Registration Statement or any Prospectus, without incurring or accruing any
obligation to pay liquidated damages pursuant to Section 2(e), no more than one
(1) time in any three month period or four (4) times in any twelve month period,
and any such period during which the availability of the Registration Statement
and any Prospectus is suspended (the "DEFERRAL PERIOD") shall, without incurring
any obligation to pay liquidated damages pursuant to Section 2(e), not exceed 30
days; provided, that in the case of a Material Event relating to an

                                       11
<PAGE>   13
acquisition or a probable acquisition or financing, recapitalization, business
combination or other similar transaction, the Company may, without incurring any
obligation to pay liquidated damages pursuant to Section 2(e), deliver to Notice
Holders a second notice to the effect set forth above, which shall have the
effect of extending the Deferral Period by up to an additional 30 days, or such
shorter period of time as is specified in such second notice, provided, that the
aggregate duration of any Deferral Periods shall not, without incurring any
obligation to pay liquidated damages pursuant to Section 2(e), exceed 30 days in
any three month period (or 60 days in any three month period in the event of a
Material Event pursuant to which the Company has delivered a second notice as
required above) or 90 days in any twelve (12) month period.

            (j) If requested in writing in connection with a disposition of
Registrable Securities pursuant to a Registration Statement and upon reasonable
notice, make, or cause the appropriate officers, directors and employees of the
Company and its subsidiaries to make, reasonably available for inspection (but
not for copying, other than for persons who are eligible for a "due diligence"
defense in connection with potential liability under Section 11 of the
Securities Act) during normal business hours by a representative for the Notice
Holders and/or Managing Underwriter, and any broker-dealers, attorneys and
accountants retained by such Notice Holders and/or Managing Underwriter, all
relevant financial information, corporate documents, properties and other
records and information reasonably requested by such representative for the
Notice Holders and/or Managing Underwriter, or any such broker-dealers,
attorneys or accountants in connection with such disposition, in each case as is
customary for similar "DUE DILIGENCE" examinations; provided, however, that such
persons shall first agree in writing with the Company that any information that
is reasonably and in good faith designated by the Company in writing as
confidential at the time of delivery of such information shall be kept
confidential by such persons and shall be used solely for the purposes of
exercising rights under this Agreement, unless (i) disclosure of such
information is required by court or administrative order or is necessary to
respond to inquiries of regulatory authorities, (ii) disclosure of such
information is required by law (including any disclosure requirements pursuant
to federal securities laws in connection with the filing of any Registration
Statement or the use of any Prospectus referred to in this Agreement), (iii)
such information becomes generally available to the public other than as a
result of a disclosure or failure to safeguard by any such person or (iv) such
information becomes available to any such person from a source other than the
Company and such source is not bound by a confidentiality agreement, and
provided, that the foregoing inspection and information gathering shall, to the
greatest extent possible, be coordinated on behalf of all the Notice Holders and
the other parties entitled thereto by the counsel referred to in Section 5 and
provided further, that the Company shall not be required to disclose any
information subject to the attorney-client or attorney work product privilege if
and to the extent such disclosure would constitute a waiver of such privilege.

            (k) Use reasonable efforts to comply with all applicable rules and
regulations of the SEC and make generally available to its securityholders
earning statements (which need not be audited) satisfying the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule
promulgated under the

                                       12
<PAGE>   14
Securities Act) no later than 45 days after the end of any 3-month period (or 90
days after the end of any 12-month period if such period is a fiscal year)
commencing on the first day of the first fiscal quarter of the Company
commencing after the effective date of a Registration Statement, which
statements shall cover said periods.

            (l) Cooperate with each Notice Holder to facilitate the timely
preparation and delivery of certificates representing Registrable Securities
sold or to be sold pursuant to a Registration Statement, which certificates
shall not bear any restrictive legends, and cause such Registrable Securities to
be in such denominations as are permitted by the Indenture and registered in
such names as such Notice Holder may request in writing at least two (2)
Business Days prior to any sale of such Registrable Securities.

            (m) Provide a CUSIP number for all Registrable Securities covered by
each Registration Statement not later than the effective date of such
Registration Statement and provide the Trustee and the transfer agent for the
Common Stock with printed certificates for the Registrable Securities that are
in a form eligible for deposit with The Depository Trust Company.

            (n) Cooperate and assist in any filings required to be made with the
National Association of Securities Dealers, Inc.

            (o) Upon (i) the filing of the Initial Registration Statement and
(ii) the effectiveness of the Initial Registration Statement, announce the same,
in each case by release to Reuters Economic Services and Bloomberg Business
News.

            SECTION 4. HOLDER'S OBLIGATIONS. Each Holder agrees, by acquisition
of the Registrable Securities, that no Holder of Registrable Securities shall be
entitled to sell any of such Registrable Securities pursuant to a Registration
Statement or to receive a Prospectus relating thereto, unless such Holder has
furnished the Company with a completed Notice and Questionnaire as required
pursuant to Section 2(d) hereof (including the information required to be
included in such Notice and Questionnaire) and the information set forth in the
next sentence. Each Notice Holder agrees promptly to furnish to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Notice Holder not misleading and any other
information regarding such Notice Holder and the distribution of such
Registrable Securities as the Company may from time to time reasonably request.
Any sale of any Registrable Securities by any Holder shall constitute a
representation and warranty by such Holder that the information relating to such
Holder and its plan of distribution is as set forth in the Prospectus delivered
by such Holder in connection with such disposition, that such Prospectus does
not as of the time of such sale contain any untrue statement of a material fact
relating to or provided by such Holder or its plan of distribution and that such
Prospectus does not as of the time of such sale omit to state any material fact
relating to or provided by such Holder or its plan of distribution necessary to
make the statements in such Prospectus, in the light of the circumstances under
which they were made, not misleading.

                                       13
<PAGE>   15
            SECTION 5. REGISTRATION EXPENSES. The Company shall bear all fees
and expenses incurred in connection with the performance by the Company of its
obligations under Sections 2 and 3 of this Agreement whether or not any of the
Registration Statements are declared effective (the "REGISTRATION Expenses").
The Registration Expenses shall include, without limitation, (i) all
registration and filing fees (including, without limitation, fees and expenses
(x) with respect to filings required to be made with the National Association of
Securities Dealers, Inc. and (y) of compliance with federal and state securities
or Blue Sky laws (including, without limitation, reasonable fees and
disbursements of the Special Counsel in connection with Blue Sky qualifications
of the Registrable Securities under the laws of such jurisdictions as the Notice
Holders of a majority of the Registrable Securities being sold pursuant to a
Registration Statement may designate), (ii) printing expenses (including,
without limitation, expenses of printing certificates for Registrable Securities
in a form eligible for deposit with The Depository Trust Company, (iii)
duplication expenses relating to copies of any Registration Statement or
Prospectus delivered to any Holders hereunder, (iv) reasonable fees and
disbursements of counsel for the Company and the Special Counsel in connection
with the Shelf Registration Statement (provided that the Company shall not be
liable for the fees and expenses of more than one separate firm for all parties
participating in any transaction hereunder), (v) reasonable fees and
disbursements of the Trustee and its counsel and of the registrar and transfer
agent for the Common Stock and (vi) Securities Act liability insurance obtained
by the Company in its sole discretion. In addition, the Company shall pay the
internal expenses of the Company (including, without limitation, all salaries
and expenses of officers and employees performing legal or accounting duties),
the expense of any annual audit, the fees and expenses incurred in connection
with the listing by the Company of the Registrable Securities on any securities
exchange on which similar securities of the Company are then listed and the fees
and expenses of any person, including special experts, retained by the Company.
Notwithstanding the provisions of this Section 5, each seller of Registrable
Securities shall pay selling expenses and all registration expenses to the
extent required by applicable law.

            SECTION 6. INDEMNIFICATION.

            (a) Indemnification By The Company. The Company shall indemnify and
hold harmless each Holder and each person, if any, who controls any Holder
(within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act) from and against any losses, liabilities, claims, damages and
expenses (including, without limitation, any legal or other expenses reasonably
incurred in connection with defending or investigating any such action or claim)
(collectively, "LOSSES"), arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement or Prospectus or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, provided, however, that
the Company shall not be liable in any such case to the extent that any such
Losses arise out of or are based upon an untrue statement or alleged untrue
statement contained in or omission or alleged omission from any of such
documents in reliance upon and conformity with any of the information

                                       14
<PAGE>   16
relating to the Holders furnished to the Company in writing by a Holder
expressly for use therein; provided further, that the indemnification contained
in this paragraph shall not inure to the benefit of any Holder of Registrable
Securities (or to the benefit of any person controlling such Holder) on account
of any such Losses arising out of or based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in any preliminary
prospectus provided in each case the Company has performed its obligations under
Section 3(a) hereof if either (A) (i) such Holder failed to send or deliver a
copy of the Prospectus with or prior to the delivery of written confirmation of
the sale by such Holder to the person asserting the claim from which such Losses
arise and (ii) the Prospectus would have corrected such untrue statement or
alleged untrue statement or such omission or alleged omission, or (B) (x) such
untrue statement or alleged untrue statement, omission or alleged omission is
corrected in an amendment or supplement to the Prospectus and (y) having
previously been furnished by or on behalf of the Company with copies of the
Prospectus as so amended or supplemented, such Holder thereafter fails to
deliver such Prospectus as so amended or supplemented, with or prior to the
delivery of written confirmation of the sale of a Registrable Security to the
person asserting the claim from which such Losses arise.

            (b) Indemnification By Holders of Registrable Securities. Each
Holder agrees severally and not jointly to indemnify and hold harmless the
Company and its respective directors and officers, and each person, if any, who
controls the Company (within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act) and any other Holder, from and against
all Losses arising out of or based upon any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement or
Prospectus or in any amendment or supplement thereto or in any preliminary
prospectus, or arising out of or based upon any omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, to the extent, but only to the extent,
that such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with information furnished
to the Company by such Holder expressly for use in such Registration Statement
or Prospectus or amendment or supplement thereto. In no event shall the
liability of any selling Holder of Registrable Securities hereunder be greater
in amount than the dollar amount of the proceeds received by such Holder upon
the sale of the Registrable Securities pursuant to the Registration Statement
giving rise to such indemnification obligation.

            (c) Conduct of Indemnification Proceedings. In case any proceeding
(including any governmental investigation) shall be instituted involving any
person in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such person (the "INDEMNIFIED PARTY") shall promptly
notify the person against whom such indemnity may be sought (the "INDEMNIFYING
PARTY") in writing and the indemnifying party, upon request of the indemnified
party, shall retain counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others the indemnifying party may
designate in such proceeding and shall pay the reasonable fees and disbursements
of such counsel related to such proceeding. In any such proceeding, any
indemnified party shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such indemnified party

                                       15
<PAGE>   17
unless (i) the indemnifying party and the indemnified party shall have mutually
agreed to the retention of such counsel or (ii) the named parties to any such
proceeding (including any impleaded parties) include both the indemnifying party
and the indemnified party and representation of both parties by the same counsel
would be inappropriate due to actual or potential differing interests between
them. It is understood that the indemnifying party shall not, in respect of the
legal expenses of any indemnified party in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the fees and
expenses of more than one separate firm (in addition to any local counsel) for
all indemnified parties, and that all such fees and expenses shall be reimbursed
as they are incurred. Such separate firm shall be designated in writing by, in
the case of parties indemnified pursuant to Section 6(a), the Holders of a
majority (with Holders of Securities deemed to be the Holders, for purposes of
determining such majority, of the number of shares of Underlying Securities into
which such Securities are or would be convertible or exchangeable as of the date
on which such designation is made) of the Registrable Securities covered by the
Registration Statement held by Holders that are indemnified parties pursuant to
Section 6(a) and, in the case of parties indemnified pursuant to Section 6(b),
the Company. The indemnifying party shall not be liable for any settlement of
any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

            (d) Contribution. To the extent that the indemnification provided
for in this Section 6 is unavailable to an indemnified party under Section 6(a)
or 6(b) hereof in respect of any Losses or is insufficient to hold such
indemnified party harmless, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such Losses (i) in such
proportion as is appropriate to reflect the relative benefits received by the
indemnifying party or parties on the one hand and the indemnified party or
parties on the other hand or (ii) if the allocation provided by clause (i) above
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the indemnifying party or parties on the one hand and of
the indemnified party or parties on the other hand in connection with the
statements or omissions that resulted in such Losses, as well as any other
relevant equitable considerations. Benefits received by the Company shall be
deemed to be equal to the total net proceeds from the initial placement pursuant
to the Purchase Agreement (before deducting expenses) of the Registrable
Securities to which such Losses relate. Benefits received by any Holder shall be
deemed to be equal to the value of receiving Registrable Securities that are
registered under the Securities Act. The relative fault of the Holders on the
one hand and the Company on the other hand shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact

                                       16
<PAGE>   18
relates to information supplied by the Holders or by the Company, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The Holders' respective
obligations to contribute pursuant to this paragraph are several in proportion
to the respective number of Registrable Securities they have sold pursuant to a
Registration Statement, and not joint.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method or allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the Losses
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding this Section 6(d), an
indemnifying party that is a selling Holder of Registrable Securities shall not
be required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities sold by such indemnifying party and
distributed to the public were offered to the public exceeds the amount of any
damages that such indemnifying party has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation.

            (e) The indemnity, contribution and expense reimbursement
obligations of the parties hereunder shall be in addition to any liability any
indemnified party may otherwise have hereunder, under the Purchase Agreement or
otherwise.

            (f) The indemnity and contribution provisions contained in this
Section 6 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by or on behalf
of any Holder or any person controlling any Holder, or the Company, or the
Company's officers or directors or any person controlling the Company and (iii)
the sale of any Registrable Securities by any Holder.

            SECTION 7. INFORMATION REQUIREMENTS. (a) The Company covenants that,
if at any time before the end of the Effectiveness Period the Company is not
subject to the reporting requirements of the Exchange Act, it will cooperate
with any Holder of Registrable Securities and take such further reasonable
action as any Holder of Registrable Securities may reasonably request in writing
(including, without limitation, making such reasonable representations as any
such Holder may reasonably request), all to the extent required from time to
time to enable such Holder to sell Registrable Securities without registration
under the Securities Act within the limitation of the exemptions provided by
Rule 144 and Rule 144A under the Securities Act and customarily taken in
connection with sales pursuant to such exemptions. Upon the written request of
any Holder of Registrable Securities, the Company shall deliver to such Holder a
written statement as to whether it has complied with such filing requirements,

                                       17
<PAGE>   19
unless such a statement has been included in the Company's most recent report
filed pursuant to Section 13 or Section 15(d) of Exchange Act. Notwithstanding
the foregoing, nothing in this Section 7 shall be deemed to require the Company
to register any of its securities (other than the Common Stock) under any
section of the Exchange Act.

            (a) The Company shall file the reports required to be filed by it
under the Exchange Act and shall comply with all other requirements set forth in
the instructions to Form S-3 in order to allow the Company to be eligible to
file registration statements on Form S-3.

            SECTION 8. MISCELLANEOUS.

            (a) No Conflicting Agreements. The Company is not, as of the date
hereof, a party to, nor shall it, on or after the date of this Agreement, enter
into, any agreement with respect to its securities that conflicts with the
rights granted to the Holders of Registrable Securities in this Agreement. The
Company represents and warrants that the rights granted to the Holders of
Registrable Securities hereunder do not in any way conflict with the rights
granted to the holders of the Company's securities under any other agreements.

            (b) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Company has obtained the written consent of Holders
of a majority of the then outstanding Underlying Securities constituting
Registrable Securities (with Holders of Securities deemed to be the Holders, for
purposes of this Section, of the number of outstanding shares of Underlying
Securities into which such Securities are or would be convertible or
exchangeable as of the date on which such consent is requested). Notwithstanding
the foregoing, a waiver or consent to depart from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holders of
Registrable Securities whose securities are being sold pursuant to a
Registration Statement and that does not directly or indirectly affect the
rights of other Holders of Registrable Securities may be given by Holders of at
least a majority of the Registrable Securities being sold by such Holders
pursuant to such Registration Statement; provided, that the provisions of this
sentence may not be amended, modified, or supplemented except in accordance with
the provisions of the immediately preceding sentence. Each Holder of Registrable
Securities outstanding at the time of any such amendment, modification,
supplement, waiver or consent or thereafter shall be bound by any such
amendment, modification, supplement, waiver or consent effected pursuant to this
Section 8(b), whether or not any notice, writing or marking indicating such
amendment, modification, supplement, waiver or consent appears on the
Registrable Securities or is delivered to such Holder.

            (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, by telecopier, by
courier guaranteeing overnight delivery or by first-class mail, return receipt
requested, and shall be deemed given (i) when made, if made by hand delivery,
(ii) upon confirmation, if made by telecopier, (iii) one (1) Business Day after
being deposited with such courier, if

                                       18

 "Dean Witter Select Equity Trust, Trust Indenture and Agreement" (the
 "Basic Agreement") dated September 30, 1993.  Such provisions as are
 incorporated by reference constitute a single instrument (the
 "Indenture").

                           WITNESSETH THAT:

           In consideration of the premises and of the mutual
 agreements herein contained, the Depositor and the Trustee agree as

                                  I.

                STANDARD TERMS AND CONDITIONS OF TRUST

 provisions contained in the Basic Agreement are herein incorporated
 by reference in their entirety and shall be deemed to be a part of
 this instrument as fully and to the same extent as though said

      credit), to the extent not used by the Trustee to purchase such
      Securities within the 90-day period following the first deposit
      of Securities in the Trust, shall be distributed to Unit Holders
      on the Distribution Date next following such 90-day period or
      such earlier date as the Depositor and the Trustee determine".

           B.   The first sentence of Section 2.06 is amended to add
      the following language after "Securities"))": "and/or cash (or a
      letter of credit in lieu of cash) with instructions to the
      Trustee to purchase one or more Additional Securities which cash
      (or cash in an amount equal to the face amount of the letter of
      credit), to the extent not used by the Trustee to purchase such
      Additional Securities within the 90-day period following the

                                  -2-

      to Unit Holders on the Distribution Date next following such 90-
      day period or such earlier date as the Depositor and the Trustee
      determine".

           C.   Article III, entitled "Administration of Trust",
      Section 3.01 Initial Cost shall be amended as follows:

                Section 3.01 Initial Cost shall be amended to
           substitute the following language:

                     "Section 3.01.  Initial Cost  The costs of
                organizing the Trust and sale of the Trust Units
                shall, to the extent of the expenses reimbursable to
                the Depositor provided below, be borne by the Unit
                Holders, provided, however, that, to the extent all of
                such costs are not borne by Unit Holders, the amount
                of such costs not borne by Unit Holders shall be borne
                by the Depositor and, provided further, however, that
                the liability on the part of the Depositor under this
                section shall not include any fees or other expenses
                incurred in connection with the administration of the
                Trust subsequent to the deposit referred to in Section
                2.01.  Upon notification from the Depositor that the
                primary offering period is concluded, the Trustee
                shall withdraw from the Account or Accounts specified
                in the Prospectus or, if no Account is therein
                specified, from the Principal Account, and pay to the
                Depositor the Depositor's reimbursable expenses of
                organizing the Trust and sale of the Trust Units in an
                amount certified to the Trustee by the Depositor.  If
                the balance of the Principal Account is insufficient
                to make such withdrawal, the Trustee shall, as
                directed by the Depositor, sell Securities identified
                by the Depositor, or distribute to the Depositor
                Securities having a value, as determined under Section
                4.01 as of the date of distribution, sufficient for
                such reimbursement.  The reimbursement provided for in
                this section shall be for the account of the
                Unitholders of record at the conclusion of the primary
                offering period and shall not be reflected in the
                computation of the Unit Value prior thereto.  As used
                herein, the Depositor's reimbursable expenses of
                organizing the Trust and sale of the Trust Units shall
                include the cost of the initial preparation and
                typesetting of the registration statement,
                prospectuses (including preliminary prospectuses), the
                indenture, and other documents relating to the Trust,
                SEC and state blue sky registration fees, the cost of
                the initial valuation of the portfolio and audit of
                the Trust, the initial fees and expenses of the

                                  -3-

                Trustee, and legal and other out-of-pocket expenses
                related thereto, but not including the expenses
                incurred in the printing of preliminary prospectuses
                and prospectuses, expenses incurred in the preparation
                and printing of brochures and other advertising
                materials and any other selling expenses.  Any cash
                which the Depositor has identified as to be used for
                reimbursement of expenses pursuant to this Section
                shall be reserved by the Trustee for such purpose and
                shall not be subject to distribution or, unless the
                Depositor otherwise directs, used for payment of
                redemptions in excess of the per-Unit amount allocable
                to Units tendered for redemption."

           D.   The third paragraph of Section 3.05 is hereby amended
      to add the following sentence after the first sentence thereof:
      "Depositor may direct the Trustee to invest the proceeds of any
      sale of Securities not required for the redemption of Units in
      eligible money market instruments selected by the Depositor
      which will include only negotiable certificates of deposit or
      time deposits of domestic banks which are members of the Federal
      Deposit Insurance Corporation and which have, together with
      their branches or subsidiaries, more than $2 billion in total
      assets, except that certificates of deposit or time deposits of
      smaller domestic banks may be held provided the deposit does not
      exceed the insurance coverage on the instrument (which currently
      is $100,000), and provided further that the Trust's aggregate
      holding of certificates of deposit or time deposits issued by
      the Trustee may not exceed the insurance coverage of such
      obligations and U.S. Treasury notes or bills (which shall be
      held until the maturity thereof) each of which matures prior to
      the earlier of the next following Distribution Date or 90 days
      after receipt, the principal thereof and interest thereon (to
      the extent such interest is not used to pay Trust expenses) to
      be distributed on the earlier of the 90th day after receipt or
      the next following Distribution Date."

           E.   The first sentence of each of Sections 3.10, 3.11 and
      3.12 is amended to insert the following language at the
      beginning of such sentence, "Except as otherwise provided in
      Section 3.13,".

           F.   The following new Section 3.13 is added:

           Section 3.13.  Extraordinary Event - Security Retention and
      Voting.  In the event the Trustee is notified of any action to
      be taken or proposed to be taken by holders of the securities
      held by the Trust in connection with any proposed merger,
      reorganization, spin-off, split-off or split-up by the issuer of
      stock or securities held in the Trust, the Trustee shall take

<PAGE>

                                  -4-

      such action or refrain from taking any action, as appropriate,
      so as to insure that the securities are voted as closely as
      possible in the same manner and in the same general proportion
      as are the securities held by owners other than the Trust.  If
      stock or securities are received by the Trustee, with or without
      cash, as a result of any merger, reorganization, spin-off,
      split-off or split-up by the issuer of stock or securities held
      in the Trust, the Trustee at the direction of the Depositor may
      retain such stock or securities in the Trust.  Neither the
      Depositor nor the Trustee shall be liable to any person for any
      action or failure to take action with respect to this section.

           G.   Section 1.01 is amended to add the following
      definition:  (9) "Deferred Sales Charge" shall mean any deferred
      sales charge payable in accordance with the provisions of
      Section 3.14 hereof, as set forth in the prospectus for a Trust.
      Definitions following this definition (9) shall be renumbered.

           H.   Section 3.05 is hereby amended to add the following
      paragraph after the end thereof:  On each Deferred Sales Charge
      payment date set forth in the prospectus for a Trust, the
      Trustee shall pay the account created pursuant to Section 3.14
      the amount of the Deferred Sales Charge payable on each such
      date as stated in the prospectus for a Trust.  Such amount shall
      be withdrawn from the Principal Account from the amounts therein
      designated for such purpose.

           I.   Section 3.06B(3) shall be amended by adding the
      following:  "and any Deferred Sales Charge paid".

           J.   Section 3.08 shall be amended by adding the following
      at the end thereof:  "In order to pay the Deferred Sales Charge,
      the Trustee shall sell or liquidate an amount of Securities at
      such time and from time to time and in such manner as the
      Depositor shall direct such that the proceeds of such sale or
      liquidation shall equal the amount required to be paid to the
      Depositor pursuant to the Deferred Sales Charge program as set
      forth in the prospectus for a Trust.

<PAGE>

                                  -5-

           K.   Section 3.14 shall be added as follows:

           Section 3.14.  Deferred Sales Charge.  If the prospectus
      for a Trust specifies a Deferred Sales Charge, the Trustee
      shall, on the dates specified in and as permitted by the
      prospectus, withdraw from the Income Account if such account is
      designated in the prospectus as the source of the payments of
      the Deferred Sales Charge, or to the extent funds are not
      available in that account or if such account is not so
      designated, from the Principal Account, an amount per Unit
      specified in the prospectus and credit such amount to a special,
      non-Trust account maintained at the Trustee out of which the
      Deferred Sales Charge will be distributed to the Depositor.  If
      the Income Account is not designated as the source of the
      Deferred Sales Charge payment or if the balances in the Income
      and Principal Accounts are insufficient to make any such
      withdrawal, the Trustee shall, as directed by the Depositor,
      either advance funds, if so agreed to by the Trustee, in an
      amount equal to the proposed withdrawal and be entitled to
      reimbursement of such advance upon the deposit of additional
      monies in the Income Account or the Principal Account, sell
      Securities and credit the proceeds thereof to such special
      Depositor's account or credit Securities in kind to such special
      Depositor's Account.  Such directions shall identify the
      Securities, if any, to be sold or distributed in kind and shall
      contain, if the Trustee is directed by the Depositor to sell a
      Security, instructions as to execution of such sales.  If a Unit
      Holder redeems Units prior to full payment of the Deferred Sales
      Charge, the Trustee shall, if so provided in the prospectus, on
      the Redemption Date, withhold from the Redemption Price payment
      to such Unit Holder an amount equal to the unpaid portion of the
      Deferred Sales Charge and distribute such amount to such special
      Depositor's account or, if the Depositor shall purchase such
      Unit pursuant to the terms of Section 5.02 hereof, the Depositor
      shall pay the Redemption Price for such Unit less the unpaid
      portion of the Deferred Sales Charge.  The Depositor may at any
      time instruct the Trustee to distribute to the Depositor cash or
      Securities previously credited to the special Depositor's
      account.

           L.   The following new Section 3.15 is added:

           Section 3.15.  Foreign Exchange Transactions; Reclaiming
      Foreign Taxes.  (a) For any Trust holding Securities denominated
      in a currency other than U.S. dollars, the Depositor shall
      direct the Trustee with respect to the circumstances under which
      foreign exchange transactions are to be entered into and
      calculations under this Indenture are to be made, in order to
      convert amounts receivable in respect of the Securities in
      foreign currencies into U.S. dollars.

<PAGE>

                                  -6-

           (b)  The Trustee shall take such action as the Sponsor
      shall direct or, if not so directed, use reasonable efforts to
      reclaim or recoup any amounts of non-U.S. tax paid by the Trust
      or withheld from Income received by the Trust to which the Trust
      may be entitled as a refund.

           M.   The following paragraphs are inserted after the first
      paragraph in Section 4.01:

           "With respect to foreign securities, each security
           listed on a securities exchange will be valued at the
           last closing sale price on the relevant stock exchange
           or if no such price exists at the closing offer price
           thereof.

           If the Trust holds securities denominated in a
           currency other than U.S. dollars, the evaluations
           shall be converted to U.S. dollars based, during the
           initial offering period, on the offering side of the
           relevant currency exchange rate, and subsequent to
           such period, on the bid side of the relevant exchange
           rate, including the cost of a forward foreign exchange
           contract in the relevant currency to correspond to the
           Trustee's settlement requirement for redemption
           requests as quoted to the Trustee by one or more banks
           designated by the Depositor, unless the Security is in
           the form of an American depository share or receipt,
           in which case the evaluations shall be based upon the
           U.S. dollar prices in the market for American
           depository shares or receipts (unless the Trustee
           deems such prices inappropriate as a basis for
           valuation)."

           N.   Reference to "Dean Witter Select Equity Trust" is
      replaced by "Morgan Stanley Dean Witter Select Equity Trust."
