         enforcement, to bankruptcy, insolvency, reorganization, moratorium or
         other similar laws affecting creditors' rights generally or by general
         principles of equity (regardless of whether enforcement is considered 
         in a proceeding at law or in equity); the Debentures are entitled to 
         the benefits of the Indenture; the Indenture has been duly qualified 
         under the Trust Indenture Act of 1939 (the "Trust Indenture Act"); and

                  (v)     Each of the Preferred Securities, Guarantee,

         result of which the Prospectus as then amended or supplemented would
         include an untrue statement of a material fact or omit to state any
         material fact necessary in order to make the statements therein, in the
         light of the circumstances under which they were made when such
         Prospectus is delivered, not misleading, or, if for any other reason it
         shall be necessary during such same period to amend or supplement the
         Prospectus or to file under the Exchange Act any document incorporated
         by reference in the Prospectus in order to comply with the Act or the

         15 months thereafter, which shall comply in all material respects with

                          the subject which, if determined adversely to the
                          Company or any of its Subsidiaries, would in the
                          aggregate have a material adverse effect on the

                          outstanding subscriptions, rights, warrants, options,
                          calls, convertible securities, commitments or sale or

                          proceeding at law or in equity); the Debentures are
                          entitled to the benefits of the Indenture; the
                          Indenture has been duly qualified under the Trust

                          Agreement and described in the Prospectus; and to the
                          best of such counsel's knowledge, there are no legal
                          or governmental proceedings pending to which the Trust
                          is a party or of which any property of the Trust is
                          the subject and no such proceedings are threatened or
                          contemplated by governmental authorities or threatened
                          by others.

                  (d)     The foregoing opinions may be limited to the laws of
         Delaware, Michigan and the federal law of the United States. In giving
         such opinion, such counsel may rely, as to matters of Delaware law,

                  (vi)    The Securities have been duly authorized for issuance
                          by the Trust and, when executed and authenticated by
                          the property trustee in accordance with the terms of
                          the Trust Agreement and delivered and paid for in
                          accordance with this Agreement, will be fully paid and
                          non-assessable undivided beneficial interests in the
                          assets of the Trust and will entitle the holders
                          thereof to the benefits of this Agreement except to
                          the extent that enforcement of the Trust Agreement may
                          be limited by (a) bankruptcy, insolvency (including,
                          without limitation, all laws relating to fraudulent
                          transfers), reorganization, morato rium or other
                          similar laws now or hereafter in effect relating to

                          of equity (regardless of whether enforcement is
                          considered in a proceeding in equity or at law); and
                          the holders of the Securities will be entitled to the
                          same limitation of personal liability extended to
                          stockholders of private corporations for profit

                          State of Delaware, except that the holders of
                          Securities may be obligated, pursuant to the Trust
                          Agreement, to make payments, including (i) to provide
                          indemnity and/or security in connection with and pay

                          of the Securities and (ii) to provide security and
                          indemnity in connection with requests of or directions
                          to the property trustee to exercise its rights and
                          powers under the Trust Agreement; the issuance of the
                          Securities is not subject to preemptive or other
                          similar rights under the Delaware Business Trust Act
                          or the Trust Agreement;

                  (vii)   The Common Securities have been duly authorized for
                          issuance by the Trust and, when executed and
                          authenticated by the property trustee in accordance
                          with the terms of the Trust Agreement and delivered
                          and paid in accordance with the Common Securities
                          Purchase Agreement, dated as of , , between the
                          Company and the Trust, will be validly issued,
                          undivided beneficial interests in the assets of the
                          Trust; the issuance of the Common Securities is not
                          subject to preemptive or other similar rights under
                          the Delaware Business Trust Act or the Trust
                          Agreement;

                  (viii)  None of the execution and delivery by the Trust of, or
                          the performance by the Trust of its obligations under,
                          this Agreement, or the issuance and sale of the
                          Securities by the Trust in accordance with the terms
                          of this Agreement or the consummation of the other
                          transactions contemplated hereby, will contravene any
                          provision of applicable law or the Trust Agreement or
                          any agreement or other instrument governed by the laws

                          order or decree applicable to the Trust as set forth
                          in the Trust's certificate, of any governmental
                          authority; and

                  (ix)    No governmental approval is required for the issuance

                          hereby, except such as have been obtained and made.

                  (g)     [On the date of the Prospectus and also] at the Time
         of Delivery, the independent accountants of the Company who have 
         certified the financial statements of the Company and its consolidated
         Subsidiaries included or incorporated by reference in the Registration
         Statement shall have furnished to the Representatives a letter, dated
         as of such date, (i) confirming that they are independent public
         accountants within the meaning of the Act and the applicable published
         rules and regulations of the Commission thereunder, (ii) stating that
         in their opinion the financial statements examined by them and included
         or incorporated by reference in the Registration Statement complied as
         to form in all material respects with the applicable accounting
         requirements of the Commission, including applicable published rules
         and regulations of the Commission, and (iii) covering, as of a date not
         more than five business days prior to the date of such letter, such
         other matters as the Representatives reasonably request;

                  (h)     That, between the date of the execution of this
         Agreement and the Time of Delivery, no material and adverse change
         shall have occurred in the business, properties or financial condition
         of the Company and its Subsidiaries, taken as a whole, which, in the
         judgment of the Representatives, impairs the marketability of the
         Securities (other than changes referred to in or contemplated by the
         Registration Statement or Prospectus);

                  (i)     On or after the date hereof (i) no downgrading shall
         have occurred in the rating accorded the Company's debt securities or
         preferred stock by any "nationally recognized statistical rating
         organization", as that term is defined by the Commission for purposes
         of Rule 436(g)(2) under the Act, [and (ii) no such organization shall
         have publicly announced that it has under surveillance or review, with
         possible negative implications, its rating of any of the Company's debt
         securities or preferred stock or the Company's financial strength or
         claims paying ability];

                  (j)     The Trust Agreement, the Guarantee and the Indenture
         shall have been executed and delivered, in each case in a form
         reasonably satisfactory to the Representatives;

                  (k)     The Securities and the shares of Common Stock issuable
         upon the conversion or exchange of the Securities and/or Debentures
         shall have been duly listed, subject to notice of issuance, on the New
         York Stock Exchange;

                  (l)     The Company shall have complied with the provisions of
         Section 4(b) hereof with respect to the furnishing of prospectuses on
         the New York Business Day next succeeding the date of this Agreement;
         and

                  (m)     The Trust and the Company shall have furnished or 
         caused to be furnished to the Representatives at the Time of Delivery
         certificates of officers of the Trust and the Company to the effect
         that to the best of such person's knowledge, information and belief (i)
         there has been no material adverse change in the business, properties
         or financial condition of the Company and its Subsidiaries, taken as a
         whole or the Trust from that set forth in the Registration Statement or
         Prospectus (other than changes referred to in or contemplated by the
         Registration Statement or Prospectus), (ii) the representations and
         warranties of the Trust and the Company herein at and as of such Time
         of Delivery are true and correct, (iii) the Trust and the Company have
         complied with all agreements and satisfied all conditions on their part
         to be performed or satisfied at or prior to the Time of Delivery, and
         (iv) no stop order suspending the effectiveness of the 


                                       17
   18



         Registration Statement has been issued and no proceedings for that 
         purpose have been initiated or threatened by the Commission.

         7.       The obligations of the Company and the Trust shall be subject,
in the discretion of the Company and the Trust, to the condition that the
Registration Statement shall be effective under the Act and no stop order
suspending the effectiveness of the Registration Statement shall have been
issued under the Act or proceedings therefor initiated or threatened by the
Commission.

         8.       (a) The Trust and the Company, jointly and severally, will, to
the extent permitted by law, indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, any preliminary
prospectus supplement, the Registration Statement, the Prospectus as amended or
supplemented and any other prospectus relating to the Securities, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse each Underwriter for any legal or other expenses reasonably incurred
by such Underwriter in connection with [investigating or] defending any such
action or claim as such expenses are incurred; provided, however, that (i)
neither the Trust nor the Company shall be liable in any such case to the extent
that any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in any Preliminary Prospectus, any preliminary prospectus supplement, the
Registration Statement, the Prospectus as amended or supplemented and any other
prospectus relating to the Securities, or any such amendment or supplement in
reliance upon and in conformity with written information furnished to the Trust
and the Company by any Underwriter through the Representatives expressly for use
in the Prospectus as amended or supplemented relating to such Securities or with
any statements in or omissions from that part of the Registration Statement that
shall constitute the Statements of Eligibility and Qualification under the Trust
Indenture Act of the Debenture Trustee, the Guarantee Trustee and the Property
Trustee, and except that this indemnity shall not inure to the benefit of any
Underwriter (or any person controlling such Underwriter) on account of any
losses, claims, damages, liabilities or actions, suits or proceedings arising
from the sale of the Securities to any person if a copy of the Prospectus, as
the same may then be supplemented or amended (excluding, however, any document
then incorporated or deemed incorporated therein by reference), was not sent or
given by or on behalf of such Underwriter to such person (i) with or prior to
the written confirmation of sale involved or (ii) as soon as available after
such written confirmation, relating to an event occurring prior to the payment
for and delivery to such person of the Securities involved in such sale, and the
omission or alleged omission or untrue statement or alleged untrue statement was
corrected in the Prospectus as supplemented or amended at such time.

                  (b)     Each Underwriter, severally and not jointly, will
         indemnify and hold harmless the Trust and the Company against any
         losses, claims, damages or liabilities to which the Trust and the
         Company may become subject, under the Act or otherwise, insofar as such
         losses, claims, damages or liabilities (or actions in respect thereof)
         arise out of or are based upon an untrue statement or alleged untrue
         statement of a material fact contained in any Preliminary Prospectus,
         any preliminary prospectus supplement, the Registration Statement, the
         Prospectus as amended or supplemented and any other prospectus relating
         to the Securities, or any amendment or supplement thereto, or arise out
         of or are based upon the omission or alleged omission to state therein
         a material fact required to be stated therein or necessary to make the
         statements therein 




                                       18
   19



         not misleading, in each case to the extent, but only to the extent,
         that such untrue statement or alleged untrue statement or omission or
         alleged omission was made in any Preliminary Prospectus, any
         preliminary prospectus supplement, the Registration Statement, the
         Prospectus as amended or supplemented and any other prospectus relating
         to the Securities, or any such amendment or supplement in reliance upon
         and in conformity with written information furnished to the Trust and
         the Company by such Underwriter through the Representatives expressly
         for use therein; and will reimburse the Trust and the Company for any
         legal or other expenses reasonably incurred by the Trust and the
         Company in connection with [investigating or] defending any such action
         or claim as such expenses are incurred.

                  (c)     If a claim is made or an action, suit or proceeding
         (including governmental investigations) is commenced or threatened
         against any person as to which indemnity may be sought under subsection
         (a) or (b), such person (the "Indemnified Person") shall notify the
         person against whom such indemnity may be sought (the "Indemnifying
         Person"), promptly after any assertion of such claim threatening to
         institute an action, suit or proceeding or if such an action, suit or
         proceeding is commenced against such Indemnified Person, promptly after
         such Indemnified Person shall have been served with a summons or other
         first legal process, giving information as to the nature and basis of
         the claim. Failure to so notify the Indemnifying Person shall not,
         however, relieve the Indemnifying Person from any liability which it
         may have on account of the indemnity under subsection (a) or (b) if the
         Indemnifying Person has not been prejudiced in any material respect by
         such failure. Subject to the immediately succeeding sentence, the
         Indemnifying Person shall assume the defense of any such litigation or
         proceeding,including the employment of counsel and the payment of all
         expenses, with such counsel being designated, subject to the
         immediately succeeding sentence, in writing by the Representatives in
         the case of parties indemnified pursuant to subsection (b) and by the
         Company in the case of parties indemnified pursuant to subsection (a).
         Any Indemnified Person shall have the right to participate in such
         litigation or proceeding and to retain its own counsel, but the fees
         and expenses of such counsel shall be at the expense of such
         Indemnified Person unless (i) the Indemnifying Person and the
         Indemnified Person shall have mutually agreed to the retention of such
         counsel or (ii) the named parties to any such proceeding (including any
         impleaded parties) include (x) the Indemnifying Person and (y) the
         Indemnified Person and, in the written opinion of counsel to such
         Indemnified Person, representation of both parties by the same counsel
         would be inappropriate due to actual or likely conflicts of interest
         between them, in either of which cases the reasonable fees and expenses
         of counsel (including disbursements) for such Indemnified Person shall
         be reimbursed by the Indemnifying Person to the Indemnified Person. If
         there is a conflict as described in clause (ii) above, and the
         Indemnified Persons have participated in the litigation or proceeding
         utilizing separate counsel whose fees and expenses have been reimbursed
         by the Indemnifying Person and the Indemnified Persons, or any of them,
         are found to be solely liable, such Indemnified Persons shall repay to
         the Indemnifying Person such fees and expenses of such separate counsel
         as the Indemnifying Person shall have reimbursed. It is understood that
         the Indemnifying Person shall not, in connection with any litigation or
         proceeding or related litigation or proceedings in the same
         jurisdiction as to which the Indemnified Persons are entitled to such
         separate representation, be liable under this Agreement for the
         reasonable fees and out-of-pocket expenses for more than one separate
         firm (together with not more than one appropriate local counsel) for
         all such Indemnified Persons. Subject to the next paragraph, all such
         fees and expenses shall be reimbursed by payment to the Indemnified
         Persons of such reasonable fees and expenses of counsel promptly after
         payment 



                                       19
   20


         thereof by the Indemnified Persons. Such firms shall be selected and 
         designated in writing by ____________.

         9.       In furtherance of the requirement above that fees and expenses
of any separate counsel for the Indemnified Persons shall be reasonable, the
Representatives and the Company agree that the Indemnifying Person's obligations
to pay such fees and expenses shall be conditioned upon the following:

                  (a)     in case separate counsel is proposed to be retained by
         the Indemnified Persons pursuant to clause (ii) of the preceding
         paragraph, the Indemnified Persons shall in good faith fully consult
         with the Indemnifying Person in advance as to the selection of such
         counsel;

                  (b)     reimbursable fees and expenses of such separate
         counsel shall be detailed and supported in a manner reasonably
         acceptable to the Indemnifying Person (but nothing herein shall be
         deemed to require the furnishing to the Indemnifying Person of any
         information, including without limitation, computer print-outs of
         lawyers' daily time entries, to the extent that, in the judgment of
         such counsel, furnishing such information might reasonably be expected
         to result in a waiver of any attorney-client privilege); and

                  (c)     the Company and the Representatives shall cooperate in
         monitoring and controlling the fees and expenses of separate counsel
         for Indemnified Persons for which the Indemnifying Person is liable
         hereunder, and the Indemnified Person shall use every reasonable
         effort to cause such separate counsel to minimize the duplication of
         activities as between themselves and counsel to the Indemnifying
         Person.

         The Indemnifying Person shall not be liable for any settlement of any
litigation or proceeding effected without the written consent of the
Indemnifying Person, but if settled with such consent or if there be a final
judgment for the plaintiff, the Indemnifying Person agrees, subject to the
provisions of this Section 8, to indemnify the Indemnified Person from and
against any loss, damage, liability or expenses by reason of such settlement or
judgment. The Indemnifying Person shall not, without the prior written consent
of the Indemnified Persons, effect any settlement of any pending or threatened
litigation, proceeding or claim in respect of which indemnity has been properly
sought by the Indemnified Persons hereunder, unless such settlement includes an
unconditional release by the claimant of all Indemnified Persons from all
liability with respect to claims which are the subject matter of such
litigation, proceeding or claim.

                  (d)     If the indemnification provided for in this Section 7
         is unavailable to or insufficient to hold harmless an indemnified party
         under subsection (a) or (b) above in respect of any losses, claims,
         damages or liabilities (or actions in respect thereof) referred to
         therein, then each indemnifying party shall contribute to the amount
         paid or payable by such indemnified party as a result of such losses,
         claims, damages or liabilities (or actions in respect thereof) in such
         proportion as is appropriate to reflect the relative benefits received
         by the Trust and the Company on the one hand and the Underwriters on
         the other from the offering of the Securities. If, however, the
         allocation provided by the immediately preceding sentence is not
         permitted by applicable law or if the indemnified party failed to give
         the notice required under subsection (c) above and such failure
         resulted in the indemnifying party being prejudiced in a material way,
         then each indemnifying party shall contribute to such amount paid or
         payable by such indemnified party in such proportion as is appropriate
         to reflect not only such relative benefits but also the relative fault
         of the Trust and the Company on the one hand and the Underwriters 



                                       20
   21




         on the other in connection with the statements or omissions which
         resulted in such losses, claims, damages or liabilities (or actions in
         respect thereof), as well as any other relevant equitable
         considerations. The relative benefits received by the Trust and the
         Company on the one hand and such Underwriters on the other shall be
         deemed to be in the same proportion as the total net proceeds from such
         offering (before deducting expenses) received by the Trust and the
         Company and the total underwriting discounts and commissions received
         by such Underwriters. The relative fault shall be determined by
         reference to, among other things, whether the untrue or alleged untrue
         statement of a material fact or the omission or alleged omission to
         state a material fact relates to information supplied by the Trust and
         the Company on the one hand or such Underwriters on the other and the
         parties' relative intent, knowledge, access to information and
         opportunity to correct or prevent such statement or omission. The
         Trust, the Company and the Underwriters agree that it would not be just
         and equitable if contributions pursuant to this subsection (d) were
         determined by pro rata allocation (even if the Underwriters were
         treated as one entity for such purpose) or by any other method of
         allocation which does not take account of the equitable considerations
         referred to above in this subsection (d). The amount paid or payable by
         an indemnified party as a result of the losses, claims, damages or
         liabilities (or actions in respect thereof) referred to above in this
         subsection (d) shall be deemed to include any legal or other expenses
         reasonably incurred by such indemnified party in connection with
         investigating or defending any such action or claim, provided that the
         provisions of subsection (c) have been complied with (in all material
         respects) in respect of any separate counsel for such indemnified
         party. Notwithstanding the provisions of this subsection (d), no
         Underwriter shall be required to contribute any amount greater than the
         excess of (i) the total price at which the Securities underwritten by
         it and distributed to the public were offered to the public over (ii)
         the amount of any damages which such Underwriter has otherwise been
         required to pay by reason of such untrue or alleged untrue statement or
         omission or alleged omission. No person guilty of fraudulent
         misrepresentation (within the meaning of Section 11(f) of the Act)
         shall be entitled to contribution from any person who was not guilty of
         such fraudulent misrepresentation. The obligations of the Underwriters
         in this subsection (d) to contribute are several in proportion to their
         respective underwriting obligations with respect to such Securities and
         not joint.

                  (e)     The obligations of the Trust and the Company under
         this Section 7 shall be in addition to any liability which the Trust
         and the Company may otherwise have and shall extend, upon the same
         terms and conditions, to each person, if any, who controls any
         Underwriter within the meaning of the Act; and the obligations of the
         Underwriters under this Section 7 shall be in addition to any liability
         which the respective Underwriters may otherwise have and shall extend,
         upon the same terms and conditions, to each officer and director of the
         Company, each Regular Trustee and to each person, if any, who controls
         the Trust and the Company within the meaning of the Act.

         10.      If any Underwriter under this Agreement shall fail or refuse
(otherwise than for some reason sufficient to justify in accordance with the
terms hereof, the termination of its obligations hereunder) to purchase the
Securities which it had agreed to purchase on the Time of Purchase, the
Representatives shall immediately notify the Company and the Representatives and
the other Underwriters may, within 36 hours of the giving of such notice,
determine to purchase, or to procure one or more other members of the National
Association of Securities Dealers, Inc. ("NASD") (or, if not members of the
NASD, who are foreign banks, dealers or institutions not registered under the
Exchange Act and who agree in making sales to comply with the NASD's Rules of
Fair Practice), satisfactory in the Company to purchase, upon the terms herein
set forth, the principal amount of Securities which the defaulting 



                                       21
   22



Underwriter had agreed to purchase. If any non-defaulting Underwriter or
Underwriters shall determine to exercise such right, the Representatives shall
give written notice to the Company of such determination within 36 hours after
the Company shall have received notice of any such default, and thereupon the
Time of Purchase shall be postponed for such period, not exceeding three
business days, as the Company shall determine. If in the event of such a
default, the Representatives shall fail to give such notice, or shall within
such 36-hour period give written notice to the Company that no other Underwriter
or Underwriters, or others, will exercise such right, then this Agreement may be
terminated by the Company, upon like notice given to the Representatives within
a further period of 36 hours. If in such case the Company shall not elect to
terminate this Agreement, it shall have the right, irrespective of such default:

                  (a)     to require such non-defaulting Underwriters to
         purchase and pay for the respective principal amounts of Securities
         which they had severally agreed to purchase hereunder, as hereinabove
         provided, and, in addition, the principal amount of Securities which
         the defaulting Underwriter shall have so failed to purchase up to a
         principal amount thereof equal to one-ninth (1/9) of the respective
         principal amounts of Securities which such non-defaulting Underwriters
         have otherwise agreed to purchase hereunder; and/or

                  (b)     to procure one or more other members of the NASD (or,
         if not members of the NASD, who are foreign banks, dealers or
         institutions not registered under the Exchange Act and who agree in
         making sales to comply with the NASD's Rules of Fair Practice), to
         purchase, upon the terms herein set forth, the principal amount of
         Securities which such defaulting Underwriter had agreed to purchase, or
         that portion thereof which the remaining Underwriters shall not be
         obligated to purchase pursuant to the foregoing clause (a).

         In the event the Company shall exercise its rights under clause (a)
and/or (b) above, the Company shall give written notice thereof to the
Representatives within such further period of 36 hours, and thereupon the Time
of Purchase shall be postponed for such period, not exceeding five business
days, as the Company shall determine. In the event the Company shall be entitled
to but shall not elect to exercise its rights under clause (a) and/or (b), the
Company shall be deemed to have elected to terminate this Agreement.

         Any action taken by the Company under this Section 9 shall not relieve
any defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement. Termination by the Company under this Section
9 shall be without any liability on the part of the Company or any
non-defaulting Underwriter.

         In the computation of any period of 36 hours referred to in this
section 9, there shall be excluded a period of 24 hours in respect of each
Saturday, Sunday or legal holiday which would otherwise be included in such
period of time.

         11.      The respective indemnities, agreements, representations,
warranties and other statements of the Trust and the Company and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Trust, the Company, or any officer, director, Regular
Trustee or controlling person of the Trust or the Company, and shall survive
delivery of and payment for the Securities.

         12.      This Agreement may be terminated at any time prior to the Time
of Delivery by the Representatives if, prior to such time, any of the following
events shall have occurred: (i) a suspension or material limitation in trading
in securities generally on the New York Stock Exchange; (ii) a suspension or
material limitation in trading in the Company's securities on the New York Stock
Exchange; (iii) a general moratorium on commercial banking activities declared
by either Federal or New York State authorities; or (iv) the outbreak or
escalation of hostilities involving the United States or the declaration by the
United States of a national emergency or war, if the effect of any such event
specified in this Clause (v) in the judgment of the Representatives makes it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Securities on the terms and in the manner contemplated in the Prospectus;

                  If the Representatives elect to terminate this Agreement, as
provided in this Section 11, the Representatives will promptly notify the
Company and each other Underwriter by telephone or telecopy, confirmed by
letter. If this Agreement shall not be carried out by any Underwriter for any
reason permitted hereunder, or if the sale of the Securities to the Underwriters
as herein contemplated shall not be carried out because the Company is not able
to comply with the terms hereof, the Company shall not be under any obligation
under this Agreement and shall not be liable to any Underwriter or to any member
of any selling group for the loss of anticipated profits from the transactions
contemplated by this Agreement and the Underwriters shall be under no liability
to the Company nor be under any liability under this Agreement to one another.

                  Notwithstanding the foregoing, the provisions of Sections 5
and 7 shall survive any termination of this Agreement.

         13.      In all dealings hereunder, the Representatives shall act on
behalf of each of the Underwriters, and the parties hereto shall be entitled to
act and rely upon any statement, request, notice or agreement on behalf of any
Underwriter made or given by the Representatives jointly or by on behalf of the
Representatives.

                  All statements, requests, notices and agreements hereunder
shall be in writing, and if to the Underwriters shall be delivered or sent by
mail, telex or facsimile transmission to the Representa tives in care of
_______________; and if to the Trust or the Company shall be delivered or sent
by mail, telex or facsimile transmission to the address of the Company set forth
in the Registration Statement, Attention: Secretary; provided, however, that any
notice to an Underwriter pursuant to Section 7(c) hereof shall be delivered or
sent by mail, telex or facsimile transmission to such Underwriter at its address
set forth in its Underwriters' Questionnaire, or telex constituting such
Questionnaire, which address will be supplied to the Trust and the Company by
the Representatives upon request. Any such statements, requests, notices or
agreements shall take effect upon receipt thereof.

         14.      This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Trust, the Company and, to the extent provided
in Sections 7 and 9 hereof, the officers, directors and administrative trustees
of the Trust, the Company and each person who controls the Trust, the Company or
any Underwriter, and their respective heirs, executors, administrators,
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement. No purchaser of any of the Securities from
any Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

         15.      Time shall be of the essence of this Agreement. As used
herein, the term "business day" shall mean any day when the Commission's office
in Washington, D.C. is open for business.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

         17.      This Agreement may be executed by any one or more of the
parties hereto and thereto in any number of counterparts, each of which shall be
deemed to be an original, but all such respective counterparts shall together
constitute one and the same instrument.
