ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Article XII of the Restated Articles of Incorporation of the Company
authorizes the Company to indemnify any present or former director or officer to
the fullest extent not prohibited by the Washington Business Corporation Act,
public policy or other applicable law. The Washington Business Corporation Act
(Sections 23B.08.510 through .570) authorizes a corporation to indemnify its
directors, officers, employees, or agents in terms sufficiently broad to permit
such indemnification under certain circumstances for liabilities (including
provisions permitting advances for expenses incurred) arising under the
Securities Act.
 
     The directors and officers of the Company are entitled to indemnification
by the Underwriters against any cause of action, loss, claim, damage, or
liability to the extent it arises out of or is based upon the failure of each
Underwriter to comply with the Prospectus delivery requirements under the
federal securities laws or any applicable state securities laws or upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in this Registration Statement and the Prospectus contained herein, as the
same shall be amended or supplemented, made in reliance upon and in conformity
with written information furnished to the Company by such Underwriter through
Goldman, Sachs & Co. expressly for use therein.
 
     In addition, the Company maintains directors' and officers' liability
insurance under which the Company's directors and officers are insured against
loss (as defined in the policy) as a result of claims brought against them for
their wrongful acts in such capacities.

ITEM 17. UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes:
 
          (1) That, for purposes of determining any liability under the
     Securities Act of 1933, each filing of the registrant's annual report
     pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act
     of 1934 (and, where applicable, each filing of an employee benefit plan's
     annual report pursuant to Section 15(d) of the Securities Exchange Act of
     1934) that is incorporated by reference in the registration statement shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
          (2) That the undersigned registrant hereby undertakes to deliver or
     cause to be delivered with the prospectus, to each person to whom the
     prospectus is sent or given, the latest annual report to security holders
     that is incorporated by reference in the prospectus and furnished
 
                                      II-2
<PAGE>   4
 
     pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under
     the Securities Exchange Act of 1934; and, where interim financial
     information required to be presented by Article 3 of Regulation S-X are not
     set forth in the prospectus, to deliver, or cause to be delivered to each
     person to whom the prospectus is sent or given, the latest quarterly report
     that is specifically incorporated by reference in the prospectus to provide
     such interim financial information.
 
          (3) That, insofar as indemnification for liabilities arising under the
     Securities Act of 1933 may be permitted to directors, officers and
     controlling persons of the registrant pursuant to the foregoing provisions,
     the registrant has been advised that in the opinion of the Securities and
     Exchange Commission such indemnification is against public policy as
     expressed in the Act and is, therefore, unenforceable. In the event that a
     claim for indemnification against such liabilities (other than the payment
     by the registrant of expenses incurred or paid by a director, officer or
     controlling person of the registrant in the successful defense of any
     action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     registrant will, unless in the opinion of its counsel the matter has been
     settled by a controlling precedent, submit to a court of appropriate
     jurisdiction the question whether such indemnification by it is against
     public policy as expressed in the Act and will be governed by a final
     adjudication of such issue.
 
          (4) That, for purposes of determining any liability under the
     Securities Act of 1933, the information omitted from the form of prospectus
     filed as part of this registration statement in reliance upon Rule 430A and
     contained in a form of prospectus filed by the registrant pursuant to Rule
     424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
     part of this registration statement as of the time it was declared
     effective.
 
          (5) That, for the purpose of determining any liability under the
     Securities Act of 1933, each post-effective amendment that contains a form
     of prospectus shall be deemed to be a new registration statement relating
     to the securities offered therein, and the offering of such securities at
     that time shall be deemed to be the initial bona fide offering thereof.

                           (xii) The Company is not an "investment company" or
                  an entity "controlled" by an "investment company," as such
                  terms are defined in the Investment Company Act;

                          (xiii) The documents incorporated by reference in the
                  Prospectus or any further amendment or supplement thereto made
                  by the Company prior to such Time of Delivery (other than the
                  financial statements and related schedules therein, as to
                  which such counsel need express no opinion), when they became
                  effective or were filed with the Commission, as the case may
                  be, complied as to form in all material respects with the
                  requirements of the Act, or the Exchange Act, as applicable,
                  and the rules and regulations of the Commission thereunder.

                       In addition, such counsel shall state that nothing has
                  come to their attention that would cause them to believe that,
                  when such documents became effective or were so filed, as the
                  case may be, contained, in the case of a registration
                  statement which became effective under the Act, an untrue
                  statement of a material fact or omitted to state a material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading, or, in the case of other
                  documents which were filed under the Exchange Act with the
                  Commission, an untrue statement of a material fact or omitted
                  to state a material fact necessary in order to make the
                  statements therein, in the light of the circumstances under
                  which they were made when such documents were so filed, not
                  misleading;

                           (xiv) The Registration Statement and the Prospectus
                  and any further amendments and supplements thereto made by the
                  Company prior to such Time of Delivery (other than the
                  financial statements and related schedules therein, as to
                  which such counsel need express no opinion) comply as to form
                  in all material respects with the requirements of the Act and
                  the rules and regulations thereunder.

                       Although they do not assume any responsibility for the
                  accuracy, completeness or fairness of the statements contained
                  in the Registration Statement or the Prospectus, except for
                  those referred to in the opinion in subsection (xi) of this
                  section 7(c), such counsel shall state that nothing has come
                  to their attention that would cause them to believe that, as
                  of its effective date, the Registration Statement or any
                  further amendment thereto made by the Company prior to such
                  Time of Delivery (other than the financial statements and
                  related schedules therein, as to which such counsel need
                  express no belief) contained an untrue statement of a material
                  fact or omitted to state a material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading or that, as of its date, the Prospectus or any

                                       15
<PAGE>   16
                  further amendment or supplement thereto made by the Company
                  prior to such Time of Delivery (other than the financial
                  statements and related schedules therein, as to which such
                  counsel need express no belief) contained an untrue statement
                  of a material fact or omitted to state a material fact
                  necessary to make the statements therein, in the light of the
                  circumstances under which they were made, not misleading or
                  that, as of such Time of Delivery, either the Registration
                  Statement or the Prospectus or any further amendment or
                  supplement thereto made by the Company prior to such Time of
                  Delivery (other than the financial statements and related
                  schedules therein, as to which such counsel need express no
                  belief) contains an untrue statement of a material fact or
                  omits to state a material fact necessary to make the
                  statements therein, in the light of the circumstances under
                  which they were made, not misleading; and, other than one or
                  more post-effective amendments to the Registration Statement
                  containing the form of Restated Articles of Incorporation of
                  the Company as filed with the State of Washington and the form
                  of completed Indenture, they do not know of any amendment to
                  the Registration Statement required to be filed or any
                  contracts or other documents of a character required to be
                  filed as an exhibit to the Registration Statement or required
                  to be described in the Registration Statement or the
                  Prospectus which are not filed or described as required.

                  (d) On the date of the Prospectus at a time prior to the
         execution of this Agreement, at 9:30 a.m., New York City time, on the
         effective date of any post-effective amendment to the Registration
         Statement filed subsequent to the date of this Agreement and also at
         each Time of Delivery, Deloitte & Touche LLP shall have furnished to
         you a letter or letters, dated the respective dates of delivery
         thereof, in form and substance satisfactory to you, to the effect set
         forth in Annex I hereto (the executed copy of the letter delivered
         prior to the execution of this Agreement is attached as Annex I(a)
         hereto and a draft of the form of letter to be delivered on the
         effective date of any post-effective amendment to the Registration
         Statement and as of each Time of Delivery is attached as Annex II(b)
         hereto);

                  (e) (i) Neither the Company nor any of its Significant
         Subsidiaries shall have sustained since the date of the latest audited
         financial statements included in the Prospectus any loss or
         interference with its business from fire, explosion, flood or other
         calamity, whether or not covered by insurance, or from any labor
         dispute or court or governmental action, order or decree, otherwise
         than as set forth or contemplated in the Prospectus, and (ii) since the
         respective dates as of which information is given in the Prospectus
         there shall not have been any change in the capital shares or long term
         debt of the Company or any of its Significant Subsidiaries or any
         change, or any development involving a prospective change, in or
         affecting the general affairs, management, financial position,
         shareholders' equity or results of operations of the Company and its
         Significant Subsidiaries, otherwise than as set forth or contemplated
         in the Prospectus, the effect of which, in any such case described in
         Clause (i) or (ii), is in the judgment of Goldman, Sachs & Co. so


                                       16

         material and adverse as to make it impracticable or inadvisable to
         proceed with the public offering or the delivery of the Shares being
         delivered at such Time of Delivery on the terms and in the manner
         contemplated in the Prospectus;

                  (f) On or after the date hereof there shall not have occurred
         any of the following: (i) a suspension or material limitation in
         trading in securities generally on the New York Stock Exchange or on
         the Nasdaq National Market; (ii) a suspension or material limitation in
         trading in the Company's securities on the Nasdaq National Market;
         (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 (iv) in the judgment
         of Goldman, Sachs & Co. makes it impracticable or inadvisable to
         proceed with the public offering or the delivery of the Shares being
         delivered at such Time of Delivery on the terms and in the manner
         contemplated in the Prospectus;

                  (g)  The Company shall have complied with the provisions of
         Section 5(c) hereof with respect to the furnishing of copies of the 
         Prospectus;

                  (h)  The Shares to be sold at such Time of Delivery shall 
         have been duly listed for quotation on Nasdaq, subject to notice of 
         issuance; and

                  (i) The Company shall have furnished or caused to be furnished
         to you at such Time of Delivery certificates of officers of the Company
         satisfactory to you as to the accuracy of the representations and
         warranties of the Company herein at and as of such Time of Delivery, as
         to the performance by the Company of all of its obligations hereunder
         to be performed at or prior to such Time of Delivery, as to the matters
         set forth in subsections (a) and (f) of this Section and as to such
         other matters as you may reasonably request.

         8. (a) The Company will 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, the Registration
Statement or the Prospectus, 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 the Company shall not 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, the Registration Statement
or the 

                                       17
<PAGE>   18
Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by or on behalf
of any Underwriter through Goldman, Sachs & Co. expressly for use therein and
provided, further, that the Company shall not be liable to any Underwriter under
the indemnity agreement in this subsection (a) with respect to any Preliminary
Prospectus to the extent that any such loss, claim, damage or liability of such
Underwriter results from the fact such Underwriter sold Shares to a person to
whom there was not sent or given, at or prior to the written confirmation of
such sale, a copy of the Prospectus as then amended or supplemented (excluding
documents incorporated by reference) in any case where such delivery is required
by the Act if the Company has previously furnished copies thereof to such
Underwriter and the loss, claim, damage or liability of such Underwriter results
from an untrue statement or omission of a material fact contained in the
Preliminary Prospectus which was corrected in the Prospectus (or the Prospectus
as amended or supplemented).

         (b) Each Underwriter will indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which 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, the Registration Statement or the
Prospectus, 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,
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, the Registration Statement or the Prospectus or any such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through Goldman, Sachs
& Co. expressly for use therein; and will reimburse the Company for any legal or
other expenses reasonably incurred by the Company in connection with
investigating or defending any such action or claim as such expenses are
incurred.

         (c) Promptly after receipt by an indemnified party under subsection (a)
or (b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against an indemnifying party
under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to 

                                       18
<PAGE>   19
such indemnified party under such subsection for any legal expenses of other
counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to,
or an admission of, fault, culpability or a failure to act, by or on behalf of
any indemnified party.

         (d) If the indemnification provided for in this Section 8 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 Company on the one hand and the Underwriters
on the other from the offering of the Shares. 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, 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 Company on the one hand and the Underwriters 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
Company on the one hand and the Underwriters on the other shall be deemed to be
in the same proportion as the total net proceeds from the offering (before
deducting expenses) received by the Company bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover page of the Prospectus. 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 Company on the one hand
or the Underwriters on the other and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission. The Company and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this subsection (e) 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 (e). 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 (e) shall be deemed to include any legal or other expenses
reasonably 


                                       19
<PAGE>   20
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this subsection (e),
no Underwriter shall be required to contribute any amount in excess of the
amount by which the total price at which the Shares underwritten by it and
distributed to the public were offered to the public exceeds the amount of any
damages 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 Underwriters' obligations in
this subsection (d) to contribute are several in proportion to their respective
underwriting obligations and not joint.

         (e) The obligations of the Company under this Section 8 shall be in
addition to any liability which 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 8 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 and to each
person, if any, who controls the Company within the meaning of the Act.

         9. (a) If any Underwriter shall default in its obligation to purchase
the Shares which it has agreed to purchase hereunder at a Time of Delivery, you
may in your discretion arrange for you or another party or other parties to
purchase such Shares on the terms contained herein. If within 36 hours after
such default by any Underwriter you do not arrange for the purchase of such
Shares, then the Company shall be entitled to a further period of 36 hours
within which to procure another party or other parties satisfactory to you to
purchase such Shares on such terms. In the event that, within the respective
prescribed periods, you notify the Company that you have so arranged for the
purchase of such Shares, or the Company notifies you that it has so arranged for
the purchase of such Shares, you or the Company shall have the right to postpone
such Time of Delivery for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus, or in any other documents or arrangements, and the
Company agrees to file promptly any amendments to the Registration Statement or
the Prospectus which in your opinion may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to this Agreement with respect to such Shares.

         (b) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased does not exceed one-eleventh of the aggregate number of all
the Shares to be purchased at such Time of Delivery, then the Company shall have
the right to require each non-defaulting Underwriter to purchase the number of
Shares which such 


                                       20
<PAGE>   21
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

         (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased exceeds one-eleventh of the aggregate number of all the
Shares to be purchased at such Time of Delivery, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the
obligations of the Underwriters to purchase and of the Company to sell the
Optional Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company except for the expenses to be borne by
the Company and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

         10. The respective indemnities, agreements, representations, warranties
and other statements of 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 Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Shares.

         11. If this Agreement shall be terminated pursuant to Section 9 hereof,
or if any Shares are not delivered by the Company as provided herein because the
condition set forth in Section 7(f) hereof has not been met, the Company shall
not then be under any liability to any Underwriter except as provided in
Sections 6 and 8 hereof; but, if for any other reason any Shares are not
delivered by or on behalf of the Company as provided herein, because the Company
failed to satisfy any of the conditions set forth in Section 7 hereof, other
than the condition set forth in 7(f), or because of any refusal or failure of
the Company to perform any agreement herein or to comply with any provisions
hereof, other than by reason of a default by an Underwriter, the Company will
reimburse the Underwriters through you for all out-of-pocket expenses approved
in writing by you, including fees and disbursements of counsel, reasonably 
incurred by the Underwriters in making preparations for the purchase, sale and
delivery of the Shares not so delivered, but the Company shall then be under no
further liability to any Underwriter except as provided in Sections 6 and 8
hereof.

         12. In all dealings hereunder, you 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 you jointly or by Goldman, Sachs & Co. on behalf of you as 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 you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail 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 8(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 has been
supplied to the Company. Any such statements, requests, notices or agreements
shall take effect upon receipt thereof.

         13. This Agreement shall be binding upon, and inure solely to the
benefit of, the Underwriters, the Company and, to the extent provided in
Sections 8 and 10 hereof, the officers and directors of the Company and each
person who controls 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 Shares from any Underwriter shall be deemed a successor or assign by
reason merely of such purchase.

         14.  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.

         15.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF NEW YORK.

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


                                       22

         If the foregoing is in accordance with your understanding, please sign
and return to us five counterparts hereof, and upon the acceptance hereof by
you, on behalf of each of the Underwriters, this letter and such acceptance
hereof shall constitute a binding agreement between each of the Underwriters and

Preferred Shares shall be entitled to receive, when, as and if declared by the
Board of Directors, out of funds of the Corporation legally available therefor,
cash dividends ("Preferred Dividends") at the annual rate of $ per share,
payable quarterly in arrears on each      ,      ,      and            in each
year (each a "Dividend Payment Date"), commencing             , 199  (and, in

Business Day immediately following such Dividend Payment Date. Preferred
Dividends shall begin to accrue from the date of initial issuance of the Series
A Preferred Shares. Preferred Dividends will cease to accrue on Series A
Preferred Shares on the Conversion Date (as defined in Section 4.4.3) or on the
date of their earlier exchange for Convertible Notes (as defined in Section
4.4.7). Preferred Dividends shall accrue on a daily basis whether or not in any

Dividend Payment Date) shall be computed on the basis of a 360-day year
consisting of twelve 30-day months. Accrued but unpaid Preferred Dividends shall
cumulate as of the Dividend Payment Date on which they first become payable, but
no interest shall accrue on accumulated but unpaid Preferred Dividends.
Preferred Dividends shall be payable to holders of record as they appear on the
stock transfer records of the Corporation on such record dates, which shall be
not more than 60 days nor less than 10 days preceding the payment dates, as
shall be fixed by the Board of Directors.

                  (b) So long as any Series A Preferred Shares are outstanding,
the Corporation may not (i) declare or pay any dividends (other than dividends
payable in Common Shares or other shares of the Corporation ranking junior to
the Series A Preferred Shares) to holders of Common Shares or shares of the
Corporation of any other class ranking on a parity with or junior

                                      -3-
<PAGE>   4
to the Series A Preferred Shares, or (ii) make any distributions of assets
(directly or indirectly, by purchase, redemption or otherwise) to the holders of
Common Shares or shares of the Corporation of any other class ranking on a
parity with or junior to the Series A Preferred Shares, unless all accrued and
unpaid Preferred Dividends, including the full dividends for the then quarterly
dividend period, shall have been paid or declared and funds sufficient for
payment thereof set apart.

                  (c) No dividends may be paid upon or declared or set apart for
any Preferred Shares ranking on a parity with the Series A Preferred Shares for
any quarterly dividend period, unless at the same time a like proportionate
dividend for the same quarterly dividend period, ratably in proportion to the
respective annual dividend rates fixed therefor, shall be paid upon or declared
or set apart for the Series A Preferred Shares.

                  4.4.3 Conversion of Series A Preferred Shares.

                  (a) Automatic Conversion on Conversion Date. On         , 1999
(the "Conversion Date"), unless previously exchanged for Convertible Notes, as
described in Section 4.4.5 below, each outstanding Series A Preferred Share
shall automatically convert into that number of Common Shares of the Corporation
determined by multiplying each Series A Preferred Share by the Exchange Rate.
However, in lieu of delivering Common Shares on the Conversion Date, the
Corporation may, at its option, convert each Series A Preferred Share into an
amount of cash (a "Cash Settlement") determined by multiplying the Current
Market Price of the Common Shares by the Exchange Rate. In either event, each
holder of Series A Preferred Shares will receive in cash any unpaid dividends
which have accrued to the Conversion Date. The Exchange Rate is equal to (i) if
the Current Market Price of the Common Shares is greater than or equal to $
per share (the "Threshold Price"), a ratio equal to the Threshold Price divided
by the Current Market Price, (ii) if the Current Market Price is less than the
Threshold Price but greater than the Initial Price, a ratio of 1.0, and (iii) if
the Current Market Price is less than or equal to the Initial Price, a ratio
equal to the Initial Price divided by the Current Market Price, subject in each
case to adjustments in certain events.

                  (b) Definitions. As used in this Article:

                           "Business Day" means any day other than a Saturday,

                           "Closing Price" of a Common Share on any date of
         determination means the closing sale price (or, if no closing price is
         reported, the last reported sale price) of such share as reported by
         The Nasdaq National Market on such date, or, if it is not so reported,
         as reported in the composite transactions for the principal United

         price is not available, the market value of a Common Share on such date
         as determined by a nationally recognized independent investment banking
         firm retained for this purpose by the Corporation.

         4.4.3(d)(ii) and (iii), means the average Closing Price per Common
         Share of the Corporation on the 20 Trading Days beginning on the
         twenty-second Trading Day immediately prior to, but not including, the
         Conversion Date and ending on the second Trading Day immediately prior
         to, but not including, the Conversion Date.

                           "Initial Price" means $________ per Common Share.

                           "Trading Day" means a day on which the Common Shares
         (i) are not suspended from trading on any national or regional

         regional securities exchange or association or over-the-counter market
         that is the primary market for the trading of such security.

                  (c) Notice of Election to Settle in Cash; No Fractional
Shares. The Corporation shall mail written notice of its election to settle the
conversion of the Series A Preferred Shares in cash to each holder of record of
Series A Preferred Shares not less than 30 Trading Days nor more than 45 Trading
Days prior to the Conversion Date. Upon surrender of certificates for Series A
Preferred Shares to be converted, as required herein (except in the case of a
Cash Settlement), the Corporation shall issue the number of full Common Shares
issuable upon conversion thereof. No fractional Common Shares will be issued
upon conversion, but in lieu thereof, in the sole discretion of the Board of
Directors, either such fractional interest shall be rounded up to the next whole
share or an amount will be paid in cash by the Corporation for such fractional
interest based upon the Current Market Price.

                  (d) Exchange Rate Adjustments. The Exchange Rate shall be
subject to adjustment from time to time as provided below in this paragraph (d).
All adjustments to the Exchange Rate shall be calculated to the nearest
1/10,000th of a Common Share.

                           (i) If the Corporation shall either:

                                    (1) pay a dividend or make a distribution
                  with respect to Common Shares in Common Shares,

                                    (2) subdivide or split its outstanding
                  Common Shares,

                                    (3) combine its outstanding Common Shares
                  into a smaller number of shares, or


                                      -5-
<PAGE>   6
                                    (4) issue by reclassification of its Common
                  Shares any capital shares of the Corporation,

         then, in any such event, the Exchange Rate in effect immediately prior
         to the record date for any such dividend or distribution or the
         effective date of any such subdivision, split, combination or
         reclassification, as the case may be, shall be adjusted so that the
         holder of a Series A Preferred Share shall be entitled to receive on
         the conversion of such Series A Preferred Share, the number of Common
         Shares of the Corporation which such holder would have owned or been
         entitled to receive upon the happening of any of the events described
         above had such Series A Preferred Share been converted at the Exchange
         Rate in effect at the time of the record date for any such dividend or
         distribution or of the effective date of any such subdivision, split,
         combination or reclassification, as the case may be. Such adjustment
         shall become effective at the opening of business on the Business Day
         next following the record date for such dividend or distribution in the
         case of a dividend or distribution, and shall become effective
         immediately after the effective date in the case of a subdivision,
         split, combination, or reclassification; and any Common Shares issuable
         in payment of a dividend shall be deemed to have been issued
         immediately prior to the close of business on the record date for such
         dividend for purposes of calculating the number of outstanding Common
         Shares under clauses (ii) and (iii) below.

                           (ii) If the Corporation shall, after the date hereof,
         issue rights or warrants to all holders of its Common Shares entitling
         them (for a period not exceeding 45 days from the date of such
         issuance) to subscribe for or purchase Common Shares at a price per
         share less than the Current Market Price of the Common Shares
         (determined pursuant to paragraph (d)(v) of this Section 4.4.3) on the
         record date for the determination of Shareholders entitled to receive
         such rights or warrants, then in each case the Exchange Rate shall be
         adjusted by multiplying the Exchange Rate in effect on such record date
         by a fraction of which the numerator shall be the number of Common
         Shares outstanding on the date of issuance of such rights or warrants,
         immediately prior to such issuance, plus the number of additional
         Common Shares offered for subscription or purchase, and of which the
         denominator shall be the number of Common Shares outstanding on the
         date of issuance of such rights or warrants, immediately prior to such
         issuance, plus the number of Common Shares which the aggregate offering
         price of the total number of Common Shares so offered for subscription
         or purchase would purchase at such Current Market Price (determined by
         multiplying such total number of shares by the exercise price of such
         rights or warrants and dividing the product so obtained by such Current
         Market Price). Common Shares owned by the Corporation or by another
         company of which a majority of the shares entitled to vote in the
         election of directors are held, directly or indirectly, by the
         Corporation shall not be deemed to be outstanding for purposes of such
         computation. Such adjustment shall become effective at the opening of
         business on the Business Day next following the record date for such
         rights or warrants. To the extent that Common Shares are not delivered
         after the expiration of such rights or warrants, the Exchange Rate
         shall be readjusted to the Exchange Rate which would then be in effect
         had the adjustment made upon the issuance of such rights or warrants
         been made upon the basis of the

                                      -6-
<PAGE>   7
         issuance of rights or warrants in respect of only the number of Common
         Shares actually delivered.

                           (iii) If the Corporation shall pay a dividend or make
         a distribution to all holders of its Common Shares consisting of
         evidences of its indebtedness or other assets (including capital shares
         of the Corporation other than Common Shares but excluding any cash
         dividends or any distributions and dividends referred to in clause (i)
         above), or shall issue to all holders of its Common Shares rights or
         warrants to subscribe for or purchase any of its securities (other than
         those referred to in clause (ii) above), then in each such case the
         Exchange Rate shall be adjusted by multiplying the Exchange Rate in
         effect on the record date for such dividend or distribution or the
         determination of shareholders entitled to receive such rights or
         warrants, as the case may be, by a fraction, of which the numerator
         shall be the Current Market Price of the Common Shares (determined
         pursuant to paragraph (d)(v) of this Section 4.4.3) on such record
         date, and of which the denominator shall be such Current Market Price
         per Common Share less the fair market value (as determined by the Board
         of Directors of the Corporation, whose determination shall be
         conclusive) as of such record date of the portion of the assets or
         evidences of indebtedness so distributed, or of such subscription
         rights or warrants, applicable to one Common Share. Such adjustment
         shall become effective on the opening of business on the Business Day
         next following the record date for such dividend or distribution or the
         determination of shareholders entitled to receive such rights or
         warrants, as the case may be.

                           (iv) Anything in this paragraph (d) notwithstanding,
         the Corporation shall be entitled to make such upward adjustments in
         the Exchange Rate, in addition to those required by this paragraph (d),
         as the Corporation in its sole discretion shall determine to be
         advisable, in order that any share dividends, subdivision of shares,
         distribution of rights to purchase shares or securities, or
         distribution of securities convertible into or exchangeable for shares
         (or any transaction which could be treated as any of the foregoing
         transactions pursuant to Section 305 of the Internal Revenue Code of
         1986, as amended) hereafter made by the Corporation to its shareholders
         shall not be taxable.

                           (v) As used in this paragraph (d), the "Current
         Market Price" of the Common Shares on any date shall be the average
         Closing Price per Common Share of the Corporation on the 20 Trading
         Days immediately prior to, but not including, the date of
         determination.

                           (vi) In any case in which this paragraph (d) shall
         require that an adjustment as a result of any event become effective at
         the opening of business on the Business Day next following a record
         date and the date fixed for conversion pursuant to paragraph (a) of
         this Section 4.4.3 occurs after such record date, but before the
         occurrence of such event, the Corporation may in its sole discretion
         elect to defer the following until after the occurrence of such event:
         (A) issuing to the holder of any Series A Preferred Shares surrendered
         for conversion the additional Common Shares issuable upon conversion


                                      -7-
<PAGE>   8
         before giving effect to such adjustment; and (B) paying to such holder
         any amount in cash in lieu of a fractional Common Share pursuant to
         paragraph (c) of this Section 4.4.3.

                  (e) Notice of Adjustments. Whenever the Exchange Rate is
adjusted as provided in paragraph (d) hereof, the Corporation will file with the
transfer agent for the Series A Preferred Shares a certificate with respect to
such adjustment, make a prompt public announcement thereof and mail a notice to
holders of the Series A Preferred Shares setting forth the adjusted Exchange
Rate, the method of calculation thereof in reasonable detail and the facts
requiring such adjustment and upon which such adjustment is based.

                  (f) Reservation of Common Shares. The Corporation shall
reserve and at all times keep available, free from preemptive rights, out of its
authorized but unissued Shares, for the purpose of effecting the conversion of
the Series A Preferred Shares, such number of shares of its duly authorized
Common Shares as will from time to time be sufficient to effect the conversion
of all outstanding Series A Preferred Shares; provided, however, that the
Corporation shall not be obligated to keep such shares available with respect to
any Series A Preferred Shares during any time that the conversion of such Series
A Preferred Shares is prohibited under a contract or other agreement between the
holder of such Series A Preferred Shares and the Corporation.

                  (g) Payment of Taxes. The Corporation will pay any and all
documentary, stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of Common Shares on the conversion of Series A Preferred
Shares pursuant to this Section 4.4.3; provided, however, that the Corporation
shall not be required to pay any tax which may be payable in respect of any
registration of transfer involved in the issue or delivery of Common Shares in a
name other than that of the registered holder of Series A Preferred Shares
redeemed or converted or to be redeemed or converted, and no such issue or
delivery shall be made unless and until the person requesting such issue has
paid to the Corporation the amount of any such tax or has established, to the
satisfaction of the Corporation, that such tax has been paid.

                  4.4.4 Adjustment For Certain Consolidations or Mergers. In
case of any consolidation or merger to which the Corporation is a party (other
than a merger or consolidation in which the Corporation is the continuing
corporation and in which the Common Shares outstanding immediately prior to the
merger or consolidation remain unchanged), or in case of any sale or transfer to
another entity of the property of the Corporation as an entirety or
substantially as an entirety, or in case of any statutory share exchange with
another entity (other than in connection with an acquisition in which the Common
Shares outstanding immediately prior to the share exchange remain unchanged),
each Series A Preferred Share shall, after consummation of such transaction, be
subject to (i) conversion at the option of the holder into the kind and amount
of securities, cash, or other property receivable upon consummation of such
transaction by a holder of the number of


                                      -8-
<PAGE>   9
Common Shares into which such Series A Preferred Shares might have been
converted immediately prior to consummation of such transaction and (ii)
conversion on the Conversion Date into the kind and amount of securities, cash,
or other property receivable upon consummation of such transaction by a holder
of the number of Common Shares into which such Series A Preferred Shares would
have been converted if the conversion on the Conversion Date had occurred
immediately prior to the date of consummation of such transaction assuming in
each case that such holder of Common Shares failed to exercise rights of
election, if any, as to the kind or amount of securities, cash, or other
property receivable upon consummation of such transaction (provided that if the
kind or amount of securities, cash, or other property receivable upon
consummation of such transaction is not the same for each nonelecting share,
then the kind and amount of securities, cash, or other property receivable upon
consummation of such transaction for each nonelecting share shall be deemed to
be the kind and amount so receivable per share by a plurality of the nonelecting
shares). The kind and amount of securities into which the Series A Preferred
Shares shall be convertible after consummation of such transaction shall be
subject to adjustment as described above under paragraph (d) of Section 4.4.3
following the date of consummation of such transaction. The Corporation may not
become a party to any such transaction unless the terms thereof are consistent
with the foregoing.

                  4.4.5 Exchangeability. (a) The Series A Preferred Shares are
exchangeable in whole, or in part, at the option of the Corporation, for the
Corporation's ___% Convertible Subordinated Notes Due 1999 (the "Convertible
Notes") on any dividend payment date beginning on __________, 199__ at the rate
of $[initial price] principal amount of Convertible Notes for each Series A
Preferred Share outstanding at the time of exchange. The Corporation may effect
such exchange only if accrued and unpaid dividends on the Series A Preferred
Shares have been paid in full. An exchange of less than all of the outstanding
Series A Preferred Shares is permitted only if, immediately after giving effect
to such exchange, (i) the aggregate outstanding principal amount of the
Convertible Notes is not less than $250,000,000, (ii) accrued and unpaid
interest on the outstanding Convertible Notes has been paid in full and certain
other requirements as specified in the related indenture for the Convertible
Notes have been satisfied, and (iii) the aggregate liquidating distribution
amount for the outstanding Series A Preferred Shares is not less than
$250,000,000. The Corporation will mail written notice of its intention to
exchange to each holder of record of the Series A Preferred Shares not less than
30 Trading Days or more than 45 Trading Days prior to the date fixed for
exchange.

                  (b) Upon the date fixed for exchange of Series A Preferred
Shares for Convertible Notes (the "Exchange Date"), if the Corporation has taken
all action required to authorize the issuance of the Convertible Notes in
exchange for Series A Preferred Shares, Series A Preferred Shares so exchanged
will no longer be deemed outstanding and all rights relating to such shares will
terminate, except only the right to receive dividends accrued and unpaid to and
including the Exchange Date and the right to receive the Convertible Notes upon
surrender of certificates representing the Series A Preferred Shares.

                  (c) In the event that Series A Preferred Shares have been
exchanged for Convertible Notes pursuant to this Section 4.4.5, the provisions
set forth under paragraphs (d), (f) and (g) of Section 4.4.3 hereof shall apply
with respect to the Convertible Notes to the same extent and to the same effect
as they would have applied to the Series A Preferred Shares.

                  4.4.6 Liquidation Rights. In the event of any liquidation,
dissolution or winding up of the Corporation, whether voluntary or involuntary,
the holders of Series A Preferred Shares are entitled to receive out of the
assets of the Corporation, whether such assets are stated capital or surplus of
any nature, before any payment is made or any assets are distributed to holders
of Common Shares and of any other class of shares of the Corporation ranking
junior to the Series A Preferred Shares, liquidating distributions in the amount
of $ per Series A Preferred Share plus accrued and unpaid dividends, whether or
not declared, without interest. If upon any liquidation, dissolution or winding
up of the Corporation, the amounts payable with respect to the Series A
Preferred Shares and any other preferred shares ranking as to any such
distribution on a parity with the Series A Preferred Shares are not paid in
full, the holders of the Series A Preferred Shares and of such other preferred
shares shall share ratably in any such distribution of assets in proportion to
the full respective preferential amounts to which they are entitled. After
payment of the full amount of the liquidating distribution to which they are
entitled, the holders of Series A Preferred Shares shall not be entitled to any
further participation in any distribution of assets by the Corporation. Neither
a consolidation nor merger of the Corporation with another corporation nor a
sale or transfer of all or part of the Corporation's assets for cash, securities
or other property shall be considered a liquidation, dissolution or winding up
of the Corporation for these purposes.

                  4.4.7 Voting Rights. Except as indicated below or otherwise
required by law, holders of Series A Preferred Shares will have no voting
rights. If (i) at any time the equivalent of six quarterly dividends payable on
the Series A Preferred Shares are accrued and unpaid or (ii) the Corporation
fails to make any payment upon mandatory redemption of the Series A Preferred
Shares, the number of directors of the Corporation shall be increased by two and
the holders of all outstanding Series A Preferred Shares, voting separately as a
class, shall be entitled to elect the additional two directors to serve until
all dividends accrued and unpaid have been paid or declared and funds set aside
to provide for payment in full or the Corporation fulfills its mandatory
redemption obligation, as the case may be.

                  In addition, without the vote or consent of the holders of at
least two-thirds of the Series A Preferred Shares then outstanding, the
Corporation may not (a) create or issue or increase the authorized number of
shares of any class or series of shares ranking prior to the Series A Preferred
Shares either as to dividends or upon liquidation, dissolution or winding up, or
any security convertible into or exercisable or exchangeable for such Shares,
(b) purchase or redeem less than all of the Series A Preferred Shares then
outstanding when any dividends on the Series A Preferred Shares are in arrears,
or (c) amend, alter or repeal any of the provisions of the Articles of
Incorporation so as to affect any right, preference, privilege or voting power
of the Series A Preferred Shares or the holders thereof; provided, however, that
any increase in the amount of authorized Preferred Shares or the creation and
issuance of any other class of Preferred Shares, or any increase in the amount
of authorized shares of such class or of any other class of Preferred Shares, in
each case ranking on a parity with or junior to the Series A Preferred Shares
with respect to the payment of dividends and the distribution of assets upon
liquidation, dissolution or winding up, shall not be deemed to affect such
rights, preferences or voting powers.

                  receive a benefit in money, property, or services to which the
                  director is not legally entitled.

If the Washington Business Corporation Act is amended to authorize corporate
action further eliminating or limiting the personal liability of directors, then
the liability of a director of the Corporation shall be eliminated or limited to
the fullest extent not prohibited by the Washington Business Corporation Act, as
so amended. The provisions of this Article shall be deemed to be a contract with
each Director of the Corporation who serves as such at any time while such
provisions are in effect, and each such Directors shall be deemed to be serving
as such in reliance on the provisions of this Article. Any repeal or
modification of the foregoing paragraph by the shareholders of the Corporation
shall not adversely affect any right or protection of a director of the
Corporation with respect to any acts or omissions of such director occurring
prior to such repeal or modification.

shall indemnify its Directors and Officers to the full extent not prohibited by
applicable law now or hereafter in force against liability arising out of a
Proceeding to which such individual was made a Party because the individual is
or was a Director or an Officer. However, such indemnity shall not apply on
account of:

         (a)      Acts or omissions of a Director or Officer finally adjudged to
                  be intentional misconduct or a knowing violation of law;

         (b)      Conduct of a Director or Officer finally adjudged to be in

                  distributions by the Corporation; or

                  that such Director or Officer personally received a benefit in
                  money, property, or services to which the Director or Officer
                  was not legally entitled.

Subject to the foregoing, it is specifically intended that Proceedings covered
by indemnification shall include Proceedings brought by the Corporation
(including derivative actions) Proceedings by government entities and
governmental officials or other third party actions.

         12.3 INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE CORPORATION. The
Corporation may, by action of its Board of Directors from time to time, provide
indemnification and pay Expenses in advance of the final disposition of a
Proceeding to Employees and Agents of the Corporation who are not also
Directors, in each case to the same extent as to a Director with respect to the
indemnification and advancement of Expenses pursuant to rights granted under, or
provided by, the Act or otherwise.

         12.4 PARTIAL INDEMNIFICATION. If an Indemnitee is entitled to
indemnification by the Corporation for some or a portion of Expenses,
liabilities, or losses actually and reasonably


                                      -14-
<PAGE>   15
incurred by Indemnitee in an investigation, defense, appeal or settlement but
not, however, for the total amount thereof, the Corporation shall nevertheless
indemnify Indemnitee for the portion of such Expenses, liabilities or losses to
which Indemnitee is entitled.

         12.5 PROCEDURE FOR SEEKING INDEMNIFICATION AND/OR ADVANCEMENT OF
EXPENSES. The following procedures shall apply in the absence of (or at the
option of the Indemnitee, in lieu thereof), specific procedures otherwise
applicable to an Indemnitee pursuant to a contract, trust agreement, or general
or specific action of the Board of Directors:

                  12.5.1 Notification and Defense of Claim. Indemnitee shall
         promptly notify the Corporation in writing of any proceeding for which
         indemnification could be sought under this Article. In addition,
         Indemnitee shall give the Corporation such information and cooperation
         as it may reasonably require and as shall be within Indemnitee's power.

         With respect to any such proceeding as to which Indemnitee has notified
         the Corporation:

                  (a)      The Corporation will be entitled to participate
                           therein at its own expense; and

                  (b)      Except as otherwise provided below, to the extent
                           that it may wish, the Corporation, jointly with any
                           other indemnifying party similarly notified, will be
                           entitled to assume the defense thereof, with counsel
                           satisfactory to Indemnitee. Indemnitee's consent to
                           such counsel may not be unreasonably withheld.

                  After notice from the Corporation to Indemnitee of its
         election to assume the defense, the Corporation will not be liable to
         Indemnitee under this Article for any legal or other Expenses
         subsequently incurred by Indemnitee in connection with such defense.
         However, Indemnitee shall continue to have the right to employ its
         counsel in such proceeding, at Indemnitee's expense; and if:

                           (i)      The employment of counsel by Indemnitee has
                                    been authorized by the Corporation;

                           (ii)     Indemnitee shall have reasonably concluded
                                    that there may be a conflict of interest
                                    between the Corporation and Indemnitee in
                                    the conduct of such defense; or

                           (iii)    The Corporation shall not in fact have
                                    employed counsel to assume the defense of
                                    such proceeding,

         the fees and Expenses of Indemnitee's counsel shall be at the expense
         of the Corporation.


                                      -15-
<PAGE>   16
                  The Corporation shall not be entitled to assume the defense of
         any proceeding brought by or on behalf of the Corporation or as to
         which Indemnitee shall reasonably have made the conclusion that a
         conflict of interest may exist between the Corporation and the
         Indemnitee in the conduct of the defense.

                  12.5.2 Information to be Submitted and Method of Determination
         and Authorization of Indemnification. For the purpose of pursuing
         rights to indemnification under this Article, the Indemnitee shall
         submit to the Board a sworn statement requesting indemnification and
         reasonable evidence of all amounts for which such indemnification is
         requested (together, the sworn statement and the evidence constitute an
         "Indemnification Statement").

                  Submission of an Indemnification Statement to the Board shall
         create a presumption that the Indemnitee is entitled to indemnification
         hereunder, and the Corporation shall, within sixty (60) calendar days
         thereafter, make the payments requested in the Indemnification
         Statement to or for the benefit of the Indemnitee, unless: (1) within
         such sixty (60) calendar day period it shall be determined by the
         Corporation that the Indemnitee is not entitled to indemnification
         under this Article; (2) such determination shall be based upon clear
         and convincing evidence (sufficient to rebut the foregoing
         presumption); and (3) the Indemnitee shall receive notice in writing of
         such determination, which notice shall disclose with particularity the
         evidence upon which the determination is based.

                  The foregoing determination may be made: (1) by the Board of
         Directors by majority vote of a quorum of Directors who are not at the
         time parties to the proceedings; (2) if a quorum cannot be obtained, by
         majority vote of a committee duly designated by the Board of Directors
         (in which designation Directors who are parties may participate)
         consisting solely of two (2) or more Directors not at the time parties
         to the proceeding; (3) by special legal counsel; or (4) by the
         shareholders as provided by Section 23B.08.550 of the Act.

                  Any determination that the Indemnitee is not entitled to
         indemnification, and any failure to make the payments requested in the
         Indemnification Statement, shall be subject to judicial review by any
         court of competent jurisdiction.

                  12.5.3 Special Procedure Regarding Advance for Expenses. An
         Indemnitee seeking payment of Expenses in advance of a final
         disposition of the proceeding must furnish the Corporation, as part of
         the Indemnification Statement:

                           (a)      A written affirmation of the Indemnitee's
                                    good faith belief that the Indemnitee has
                                    met the standard of conduct required to be
                                    eligible for indemnification; and


                                      -16-
<PAGE>   17
                           (b)      A written undertaking, constituting an
                                    unlimited general obligation of the
                                    Indemnitee, to repay the advance if it is
                                    ultimately determined that the Indemnitee
                                    did not meet the required standard of
                                    conduct.

                  Upon satisfaction of the foregoing the Indemnitee shall have a
         contractual right to the payment of such Expenses.

                  12.5.4 Settlement. The Corporation is not liable to indemnify
         Indemnitee for any amounts paid in settlement of any proceeding without
         the Corporation's written consent. The Corporation shall not settle any
         proceeding in any manner which would impose any penalty or limitation
         on Indemnitee without Indemnitee's written consent. Neither the
         Corporation nor Indemnitee may unreasonably withhold its consent to a
         proposed settlement.

         12.6.    CONTRACT AND RELATED RIGHTS.

                  12.6.1 Contract Rights. The right of an Indemnitee to
         indemnification and advancement of Expenses is a contract right upon
         which the Indemnitee shall be presumed to have relied in determining to
         serve or to continue to serve in his or her capacity with the
         Corporation. Such right shall continue as long as the Indemnitee shall
         be subject to any possible proceeding. Any amendment to or repeal of
         this Article shall not adversely affect any right or protection of an
         Indemnitee with respect to any acts or omissions of such Indemnitee
         occurring prior to such amendment or repeal.

                  12.6.2 Optional Insurance, Contracts, and Funding. The
                  Corporation may:

                           (a)      Maintain insurance, at its expense, to
                                    protect itself and any Indemnitee against
                                    any liability, whether or not the
                                    Corporation would have power to indemnify
                                    the individual against the same liability
                                    under Section 23B.08.5 10 or .520 of the
                                    Act;

                           (b)      Enter into contracts with any Indemnitee in
                                    furtherance of this Article and consistent
                                    with the Act; and

                           (c)      Create a trust fund, grant a security
                                    interest, or use other means (including
                                    without limitation a letter of credit) to
                                    ensure the payment of such amounts as may be
                                    necessary to effect indemnification as
                                    provided in this Article.

                  12.6.3 Severability. If any provision or application of this
         Article shall be invalid or unenforceable, the remainder of this
         Article and its remaining applications shall not be affected thereby,
         and shall continue in full force and effect.


                                      -17-
<PAGE>   18
                  12.6.4 Right of Indemnitee to Bring Suit. If (1) a claim under
         this Article for indemnification is not paid in full by the Corporation
         within sixty (60) days after a written claim has been received by the
         Corporation; or (2) a claim under this Article for advancement of
         Expenses is not paid in full by the Corporation within twenty (20) days
         after a written claim has been received by the Corporation, then the
         Indemnitee may, but need not, at any time thereafter bring suit against
         the Corporation to recover the unpaid amount of the claim. To the
         extent successful in whole or in part, the Indemnitee shall be entitled
         to also be paid the expense (to be proportionately prorated if the
         Indemnitee is only partially successful) of prosecuting such claim.
         Neither (1) the failure of the Corporation (including its Board of
         Directors, its shareholders, or independent legal counsel) to have made
         a determination prior to the commencement of such proceeding that
         indemnification or reimbursement or advancement of Expenses to the
         Indemnitee is proper in the circumstances; nor (2) an actual
         determination by the Corporation (including its Board of Directors, its
         shareholders, or independent legal counsel that the Indemnitee is not
         entitled to indemnification or to the reimbursement or advancement of
         Expenses, shall be a defense to the proceeding or create a presumption
         that the Indemnitee is not so entitled.

                  12.6.5 Nonexclusivity of Rights. The right to indemnification
         and the payment of Expenses incurred in defending a Proceeding in
         advance of its final disposition granted in this Article shall not be
         exclusive of any other right which any Indemnitee may have or hereafter
         acquire under any statute, provision of this Article or the Bylaws,
         agreement, vote of shareholders or disinterested directors, or
         otherwise. The Corporation shall have the express right to grant
         additional indemnity without seeking further approval or satisfaction
         by the shareholders. All applicable indemnity provisions and any
         applicable law shall be interpreted and applied so as to provide an
         Indemnitee with the broadest but nonduplicative indemnity to which he
         or she is entitled.

         12.7 CONTRIBUTION. If the indemnification provided in Section 12.2 of
this Article is not available to be paid to Indemnitee for any reason other than
those set forth in subparagraphs 12.2(a), 12.2(b), and 12.2(c) of Section 12.2
of this Article (for example, because indemnification is held to be against
public policy even though otherwise permitted under Section 12.2) then in
respect of any proceeding in which the Corporation is jointly liable with
Indemnitee (or would be if joined in such proceeding), the Corporation shall
contribute to the amount of loss paid or payable by Indemnitee in such
proportion as is appropriate to reflect:

                           The relative benefits received by the Corporation on
                           the one hand and the Indemnitee on the other hand
                           from the transaction from which such proceeding
                           arose, and

                           The relative fault of the Corporation on the one hand
                           and the Indemnitee on the other hand in connection
                           with the events which resulted in such loss, as well
                           as any other relevant equitable consideration.


                                      -18-
<PAGE>   19
         The relative benefits received by and fault of the Corporation on the
one hand and the Indemnitee on the other shall be determined by a court of
appropriate jurisdiction (which may be the same court in which the proceeding
took place) with reference to, among other things, the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent the
circumstances resulting in such loss. The Corporation agrees that it would not
be just and equitable if a contribution pursuant to this Article was determined
by pro rata allocation or any other method of allocation which does not take
account of the foregoing equitable considerations.

         12.8 EXCEPTIONS. Any other provision herein to the contrary
notwithstanding, the Corporation shall not be obligated pursuant to the terms of
these Articles to indemnify or advance Expenses to Indemnitee with respect to
any proceeding.

                  12.8.1 Claims Initiated by Indemnitee. Initiated or brought
         voluntarily by Indemnitee and not by way of defense, but such
         indemnification or advancement of Expenses may be provided by the
         Corporation in specific cases if the Board of Directors finds it to be
         appropriate. Notwithstanding the foregoing, the Corporation shall
         provide indemnification including the advancement of Expenses with
         respect to Proceedings brought to establish or enforce a right to
         indemnification under these Articles or any other statute or law or as
         otherwise required under the statute.

                  12.8.2 Lack of Good Faith. Instituted by Indemnitee to enforce
         or interpret this Article, if a court of competent jurisdiction
         determines that each of the material assertions made by Indemnitee in
         such proceeding was not made in good faith or was frivolous.

                  12.8.3 Insured Claims. For which any of the Expenses or
         liabilities for indemnification is being sought have been paid directly
         to Indemnitee by an insurance carrier under a policy of officers' and
         directors' liability insurance maintained by the Corporation.

                  12.8.4 Prohibited by Law. If the Corporation is prohibited by
         the Act or other applicable law as then in effect from paying such
         indemnification and/or advancement of Expenses. For example, the
         Corporation and Indemnitee acknowledge that the Securities and Exchange
         Commission ("SEC") has taken the position that indemnification is not
         possible for liabilities arising under certain federal securities laws.
         Indemnitee understands and acknowledges that the Corporation has
         undertaken or may be required in the future to undertake with the SEC
         to submit the question of indemnification to a court in certain
         circumstances for a determination of the Corporation's right to
         indemnify Indemnitee.

         12.9 SUCCESSORS AND ASSIGNS. All obligations of the Corporation to
indemnify any Director or Officer shall be binding upon all successors and
assigns of the Corporation (including any transferee of all or substantially all
of its assets and any successor by merger or other-wise by operation of law).
The Corporation shall not effect any sale of substantially all of its assets,
merger, consolidation, or other reorganization, in which it is not the surviving
entity, unless the surviving entity agrees in writing to assume all such
obligations of the Corporation.

                   CORPORATION'S ACQUISITION OF ITS OWN SHARES

         The Corporation may purchase, redeem, receive, take or otherwise
acquire, own and hold, sell, lend, exchange, transfer or otherwise dispose of,
pledge, use and otherwise deal with and in its own shares. As a specific
modification of Section 23B.06.310 of the Act, pursuant to the authority in
Section 23B.02.020(5)(c) of the Act, to include provisions related to the
management of the business and the regulation of the affairs of the Corporation,
shares of the Corporation's stock acquired by it pursuant to this Article shall
be considered "Treasury Stock" and so held by the Corporation. The shares so
acquired by the Corporation shall not be considered as authorized and unissued
but rather as authorized, issued, and held by the Corporation. The shares, so
acquired shall not be regarded as cancelled or as a reduction to the authorized
capital of the Corporation unless specifically so designated by the Board of
Directors in an amendment to these Articles of Incorporation. The provisions of
this Article do not alter or effect the status of the Corporation's acquisition
of its shares as a "distribution" by the Corporation as defined in Section
23B.01.400(6) of the Act, nor alter or effect the limitations on distributions
by the Corporation as set forth in Section 23B.06.400 of the Act. Any shares so
acquired by the Corporation, unless otherwise specifically designated by the
Board of Directors, at the time of acquisition, shall be considered on
subsequent disposition, as transferred rather than reissued. Nothing in this
Article limits or restricts the right of the Corporation to resell or otherwise
dispose of any of its shares previously acquired for such consideration and
according to such procedures as established by the Board of Directors.


         The undersigned has signed these Restated Articles of Incorporation as
of December __, 1996.

                  Any certificate or opinion of an officer of the Company may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel 

                                      -9-

<PAGE>   20
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Company stating
that the information with respect to such factual matters is in the possession
of the Company, unless such counsel knows, or in the exercise of reasonable care
should know, that the certificate or opinion or representations with respect to
such matters are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Indenture, they may, but need not, be consolidated
and form one instrument.

SECTION 104. Acts of Holders; Record Dates.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 601) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.

                  (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be 

                                      -10-

<PAGE>   21
proved in any other manner which the Trustee deems sufficient.

                  (c) The Company may, in the circumstances permitted by the
Trust Indenture Act, fix any day as the record date for the purpose of
determining the Holders entitled to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action, or to vote on
any action, authorized or permitted to be given or taken by Holders. If not set
by the Company prior to the first solicitation of a Holder made by any Person in
respect of any such action, or, in the case of any such vote, prior to such
vote, the record date for any such action or vote shall be the 30th day (or, if
later, the date of the most recent list of Holders required to be provided
pursuant to Section 701) prior to such first solicitation or vote, as the case
may be. With regard to any record date, only the Holders on such date (or their
duly designated proxies) shall be entitled to give or take, or vote on, the
relevant action.

                  (d) The ownership of Securities shall be proved by the
Security Register.

                  (e) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

SECTION 105. Notices, Etc., to Trustee and Company.

                  Any request, demand, authorization, direction, notice,
consent, waiver or Act of Holders or other document provided or permitted by
this Indenture to be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: _______________, or

                  (2) the Company by the Trustee or by any Holder shall be
         sufficient for every purpose hereunder (unless 

                                      -11-

<PAGE>   22
         otherwise herein expressly provided) if in writing and mailed,
         first-class postage prepaid, to the Company addressed to it at the
         address of its principal office specified in the first paragraph of
         this instrument or at any other address previously furnished in writing
         to the Trustee by the Company.

SECTION 106. Notice to Holders; Waiver.

                  Where this Indenture provides for notice to Holders of any
event, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each Holder affected by such event, at his address as it appears in the Security
Register, not later than the latest date (if any), and not earlier than the
earliest date (if any), prescribed for the giving of such notice. In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders. Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice. Waivers of
notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

                  In case by reason of the suspension of regular mail service or
by reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

SECTION 107. Conflict with Trust Indenture Act.

                  If any provision hereof limits, qualifies or conflicts with a
provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any
provision of this Indenture modifies or excludes any provision of the Trust
Indenture Act that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the case
may be.

                  All covenants and agreements in this Indenture by the Company
shall bind its successors and assigns, whether so expressed or not.

SECTION 110. Separability Clause.

                  In case any provision in this Indenture or in the Securities
shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

SECTION 111. Benefits of Indenture.

                  Nothing in this Indenture or in the Securities, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder, the holders of Senior Indebtedness and the Holders of
Securities, any benefit or any legal or equitable right, remedy or claim under
this Indenture.

SECTION 112. Governing Law.

                  This Indenture and the Securities shall be governed by and
construed in accordance with the laws of the State of New York.

SECTION 113. Legal Holidays.

                  In any case where any Interest Payment Date or Stated Maturity
of any Security shall not be a Business Day, then (notwithstanding any other
provision of this Indenture or of the Securities) payment of interest or
principal need not be made on such date, but may be made on the next succeeding
Business Day with the same force and effect as if made on the Interest Payment
Date or at the Stated Maturity, provided that no interest shall accrue for the
period from

prior to the Conversion Date. In the case of election by the Company to pay the
Conversion Amount in Common Shares the Company will issue the number of full
Common Shares issuable in payment thereof. No fractional Common Shares will be
issued on payment of the Conversion Amount, but in lieu thereof, such fractional
interest shall be rounded down to the next whole share or an amount will be paid

                  The indebtedness evidenced by this Security is, to the extent
provided in the Indenture, subordinate and subject in right of payment to the
prior payment in full of all Senior Indebtedness, and this Security is issued
subject to the provisions of the Indenture with respect thereto. Each Holder of
this Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
action as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes.

principal amount of the Securities at the time Outstanding, on behalf of the
holders of all the Securities, to waive compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the holders of the Securities
shall be conclusive and binding upon such holders and upon all future holders of
the Securities and of any Security issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

withdrawal of an interest in this Security (including upon an exchange,
transfer, redemption or repurchase of this Security in part only) effected in
accordance with the Applicable Procedures, the Security Registrar, upon receipt

make an adjustment on its records to reflect an increase or decrease of the
Outstanding principal amount of this Security resulting from such deposit or
withdrawal, as the case may be.]

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed or to convert this Security as provided in the

writing, and thereupon one or more new Securities, of authorized denominations
and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

tax or other governmental charge payable in connection therewith.

<PAGE>   32
deliver, on such dividend payment date, in accordance with this Indenture such
amount of Securities as are specified by the Company to be issued in such
exchange. The Company will mail written notice to the Trustee of its intention
to exchange Series A Preferred Shares for Securities not less than 30 Trading
Days prior to the date fixed for exchange.
    

SECTION 302.  Denominations.

                  The Securities will be evidenced by one or more Global
Securities, in fully registered form without coupons, deposited with a custodian
for and registered in the name of the Depository or a nominee of the Depositary.
The Securities will be in denominations of $[initial price].


SECTION 303. Execution, Authentication, Delivery and Dating.

                  The Securities shall be executed on behalf of the Company by
its Chairman of the Board, its Vice Chairman of the Board, its President or one
of its Vice Presidents, under its corporate seal reproduced thereon attested by
its Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities may be manual or facsimile.

                  Securities bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities.

                  At any time and from time to time after the execution and
delivery of this Indenture, the Company may deliver Securities executed by the
Company to the Trustee for authentication, together with a Company Order for the
authentication and delivery of such Securities; and the Trustee in accordance
with such Company Order shall authenticate and deliver such Securities as in
this Indenture provided and not otherwise.

                  Each Security shall be dated the date of its authentication.

                  No Security shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of


                                  -22-
<PAGE>   33
authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder.


SECTION 304.  Temporary Securities.

                  Pending the preparation of definitive Securities, if any, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities.

                  If temporary Securities are issued, the Company will cause
definitive Securities to be prepared without unreasonable delay. After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Company designated pursuant to Section
1002, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations. Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.


SECTION 305. Registration, Registration of Transfer and Exchange.

                  (a) The Company shall cause to be kept at the Corporate Trust
Office of the Trustee a register (the register maintained in such office and in
any other office or agency designated pursuant to Section 1002 being herein
sometimes collectively referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall provide
for the registration of Securities and of transfers of Securities. The Trustee
is hereby appointed "Security Registrar" for the purpose of registering
Securities and transfers of Securities as herein provided.


                                      -23-
<PAGE>   34
                  Upon surrender for registration of transfer of any Security at
an office or agency of the Company designated pursuant to Section 1002 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate principal
amount.

                  At the option of the Holder, Securities may be exchanged for
other Securities of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Securities to be exchanged at such
office or agency. Whenever any Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Securities which the Holder making the exchange is entitled to receive.

                  All Securities issued upon any registration of transfer or
exchange of Securities shall be the valid obligations of the Company, evidencing
the same debt, and entitled to the same benefits under this Indenture, as the
Securities surrendered upon such registration of transfer or exchange.

                  Every Security presented or surrendered for registration of
transfer or for exchange shall (if so required by the Company or the Trustee) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

                  No service charge shall be made for any registration of
transfer or exchange of Securities, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 906 or 1201 not involving any transfer.

                  (b) The provisions of Clauses (1), (2), (3), (4) and (5) below
shall apply only to Global Securities:

                  (1) Each Global Security authenticated under this Indenture
         shall be registered in the name of the Depositary or a nominee thereof
         and delivered to the Depositary or a nominee thereof or custodian
         therefor, and each such Global Security shall constitute a single
         Security for all purposes of this Indenture.


                                      -24-
<PAGE>   35
                  (2) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         or a nominee thereof unless (A) the Depositary (i) has notified the
         Company that it is unwilling or unable to continue as Depositary for
         such Global Security and the Company thereupon fails to appoint a
         successor Depository or (ii) has ceased to be a clearing agency
         registered under the Exchange Act, (B) the Company, at its option,
         notifies the Trustee in writing that it elects to cause the issuance of
         the Securities in definitive registered certificated form or (C) there
         shall have occurred and be continuing an Event of Default or any event
         which after notice or lapse of time or both would be an Event of
         Default with respect to the Securities evidenced by such Global
         Security.

                  (3) If any Global Security is to be exchanged for other
         Securities or cancelled in whole, it shall be surrendered by or on
         behalf of the Depositary or its nominee to the Trustee, as Security
         Registrar, for exchange or cancellation as provided in this Article
         Three. If any Global Security is to be exchanged for other Securities
         or cancelled in part, or if another Security is to be exchanged in
         whole or in part for a beneficial interest in any Global Security, then
         either (i) such Global Security shall be so surrendered for exchange or
         cancellation as provided in this Article Three or (ii) the principal
         amount thereof shall be reduced or increased by an amount equal to the
         portion thereof to be so exchanged or cancelled, or equal to the
         principal amount of such other Security to be so exchanged for a
         beneficial interest therein, as the case may be, by means of an
         appropriate adjustment made on the records of the Trustee, as Security
         Registrar, whereupon the Trustee, in accordance with the Applicable
         Procedures, shall instruct the Depositary or its authorized
         representative to make a corresponding adjustment to its records. Upon
         any such surrender or adjustment of a Global Security, the Trustee
         shall, subject to Section 305(b)(2) and as otherwise provided in this
         Article Three, authenticate and deliver any Securities issuable in
         exchange for such Global Security (or any portion thereof) to or upon
         the order of, and registered in such names as may be directed by, the
         Depositary or its authorized representative. Upon


                                      -25-
<PAGE>   36
         the request of the Trustee in connection with the occurrence of any of
         the events specified in the preceding paragraph, the Company shall
         promptly make available to the Trustee a reasonable supply of
         Securities that are not in the form of Global Securities. The Trustee
         shall be entitled to rely upon any order, direction or request of the
         Depositary or its authorized representative which is given or made
         pursuant to this Article Three if such order, direction or request is
         given or made in accordance with the Applicable Procedures.

                  (4) Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a Global
         Security or any portion thereof, whether pursuant to this Section ,
         Section 304, 306, or 906 or otherwise, shall be authenticated and
         delivered in the form of, and shall be, a Global Security, unless such
         Security is registered in the name of a Person other than the
         Depositary or a nominee thereof.

                  (5) None of the Company, the Trustee, any agent of the
         Trustee, any Paying Agent or the Security Registrar will have any
         responsibility or liability for any aspect of the Depository's records
         (or the records of the participant of such Depository) relating to or
         payments made on account of beneficial ownership interests of a Global
         Security or for maintaining, supervising or reviewing any records of
         the Depository relating to such beneficial ownership interests.


SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

                  If any mutilated Security is surrendered to the Trustee, the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

                  If there shall be delivered to the Company and the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen


                                      -26-
<PAGE>   37

Security, a new Security of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Security
has become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

                  Upon the issuance of any new Security under this Section , the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new Security issued pursuant to this Section in lieu of
any destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities duly issued hereunder.

                  The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.


SECTION 307. Payment of Interest; Interest Rights Preserved.

                  Interest on any Security which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the
Person in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest.

                  Any interest on any Security which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:


                                      -27-
<PAGE>   38
                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Securities (or their
         respective Predecessor Securities) are registered at the close of
         business on a Special Record Date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner. The Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed to be paid on each Security and the date of the proposed
         payment, and at the same time the Company shall deposit with the
         Trustee an amount of money equal to the aggregate amount proposed to be
         paid in respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         Clause provided. Thereupon the Trustee shall fix a Special Record Date
         for the payment of such Defaulted Interest which shall be not more than
         15 days and not less than 10 days prior to the date of the proposed
         payment and not less than 10 days after the receipt by the Trustee of
         the notice of the proposed payment. The Trustee shall promptly notify
         the Company of such Special Record Date and, in the name and at the
         expense of the Company, shall cause notice of the proposed payment of
         such Defaulted Interest and the Special Record Date therefor to be
         mailed, first-class postage prepaid, to each Holder at his address as
         it appears in the Security Register, not less than 10 days prior to
         such Special Record Date. Notice of the proposed payment of such
         Defaulted Interest and the Special Record Date therefor having been so
         mailed, such Defaulted Interest shall be paid to the Persons in whose
         names the Securities (or their respective Predecessor Securities) are
         registered at the close of business on such Special Record Date and
         shall no longer be payable pursuant to the following Clause (2).

                  (2) The Company may make payment of any Defaulted Interest in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which the Securities may be listed, and upon
         such notice as may be required by such exchange, if, after notice given
         by the Company to the Trustee of the proposed payment


                                      -28-
<PAGE>   39
         pursuant to this Clause, such manner of payment shall be deemed
         practicable by the Trustee.

                  Subject to the foregoing provisions of this Section , each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.


SECTION 308.  Persons Deemed Owners.

                  Prior to due presentment of a Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered as the owner of

to Section 307) interest on such Security and for all other purposes whatsoever,

transfer or exchange or conversion shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by
it. The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly cancelled by the Trustee. No Securities shall be authenticated
in lieu of or in exchange for any Securities cancelled as provided in this
Section , except as expressly permitted by this Indenture. All cancelled
Securities held by the Trustee shall be disposed of as directed by a Company
Order.

SECTION  502.     Acceleration of Maturity; Rescission and Annulment.

                  If an Event of Default occurs and is continuing, then and in
every such case the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Securities may declare the principal of all the
Securities to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by Holders), and upon any such declaration
such principal shall become immediately due and payable.

                  At any time after such a declaration of acceleration has been
made and before a judgment or decree for payment of the money due has been
obtained by the Trustee as hereinafter in this Article provided, the Holders of
a majority in principal amount of the Outstanding Securities, by written notice
to the Company and the Trustee, may rescind and annul such declaration and its
consequences if

                  (1) the Company has paid or deposited with the Trustee a sum
         sufficient to pay

                           (A)  all overdue interest on all Securities,

                           (B) the principal (which for purposes of this
                  Indenture shall be deemed to include

                  the Conversion Amount with respect to any Security for which a
                  Conversion Amount is applicable pursuant to Section 1201) of
                  any Securities which have become due otherwise than by such
                  declaration of acceleration and interest thereon at the rate
                  borne by the Securities,

                           (C) to the extent that payment of such interest is
                  lawful, interest upon overdue interest at the rate borne by
                  the Securities, and

                           (D) all sums paid or advanced by the Trustee
                  hereunder and the reasonable compensation, expenses,
                  disbursements and advances of the Trustee, its agents and
                  counsel;

and

                  (2) all Events of Default, other than the non-payment of the
         principal of Securities which have become due solely by such
         declaration of acceleration, have been cured or waived as provided in
         Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.


SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

                  The Company covenants that if

                  (1) default is made in the payment of any interest on any
         Security when such interest becomes due and payable and such default
         continues for a period of 30 days, or

                  (2) default is made in the payment of the principal (which for
         purposes of this Indenture shall be deemed to include the Conversion
         Amount with respect to any Security for which a Conversion Amount is
         applicable pursuant to Section 1201) of any Security at the Maturity
         thereof,


                                      -34-
<PAGE>   45
the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal and interest, and, to the extent that payment of such
interest shall be legally enforceable, interest on any overdue principal and on
any overdue interest, at the rate borne by the Securities, and, in addition
thereto, such further amount as shall be sufficient to cover the costs and
expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

                  If an Event of Default occurs and is continuing, the Trustee
may in its discretion proceed to protect and enforce its rights and the rights
of the Holders by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any such rights, whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.


SECTION 504.  Trustee May File Proofs of Claim.

                  In case of any judicial proceeding relative to the Company (or
any other obligor upon the Securities), its property or its creditors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or
otherwise, to take any and all actions authorized under the Trust Indenture Act
in order to have claims of the Holders and the Trustee allowed in any such
proceeding. In particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same; and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 607.

                  No provision of this Indenture shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof or to


                                      -35-

authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding.


SECTION 505. Trustee May Enforce Claims Without Possession of Securities.

                  All rights of action and claims under this Indenture or the
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.


SECTION 506.  Application of Money Collected.

                  Subject to Article Eleven any money collected by the Trustee
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money on
account of principal or interest, upon presentation of the Securities and the
notation thereon of the payment if only partially paid and upon surrender
thereof if fully paid:

                  FIRST: To the payment of all amounts due the Trustee under
         Section 607; and

                  SECOND: To the payment of the amounts then due and unpaid for
         principal of and interest on the Securities in respect of which or for
         the benefit of which such money has been collected, ratably, without

         payable on such Securities for principal and interest, respectively.


SECTION 507.  Limitation on Suits.

                  No Holder of any Security shall have any right to institute
any proceeding, judicial or otherwise, with respect to this Indenture, or for

<PAGE>   47
receiver or trustee, or for any other remedy hereunder, unless

                  (1) such Holder has previously given written notice to the
         Trustee of a continuing Event of Default;

                  (2) the Holders of not less than 25% in principal amount of
         the Outstanding Securities shall have made written request to the
         Trustee to institute proceedings in respect of such Event of Default in
         its own name as Trustee hereunder;

                  (3) such Holder or Holders have offered to the Trustee
         reasonable indemnity against the costs, expenses and liabilities to be
         incurred in compliance with such request;

                  (4) the Trustee for 60 days after its receipt of such notice,
         request and offer of indemnity has failed to institute any such
         proceeding; and

                  (5) no direction inconsistent with such written request has
         been given to the Trustee during such 60-day period by the Holders of a
         majority in principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.


SECTION 508. Unconditional Right of Holders to Receive Principal and Interest
and to Convert.

                  Notwithstanding any other provision in this Indenture, the
Holder of any Security shall have the right, which is absolute and
unconditional, to receive payment of the principal of and (subject to Section
307) interest on such Security on the respective Stated Maturities expressed in
such Security and to convert such Security in accordance with Article Twelve and
to institute suit for the enforcement of any such payment and right to convert,
and


                                      -37-
<PAGE>   48
such rights shall not be impaired without the consent of such Holder.


SECTION 509.  Restoration of Rights and Remedies.

                  If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.


SECTION 510.  Rights and Remedies Cumulative.

                  Except as otherwise provided with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.


SECTION 511. Delay or Omission Not Waiver.

                  No delay or omission of the Trustee or of any Holder of any
Security to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein. Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by the Trustee or by the Holders,
as the case may be.


SECTION 512.  Control by Holders.

                  The Holders of a majority in principal amount of the
Outstanding Securities shall have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, provided that

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.


SECTION 513.  Waiver of Past Defaults.

                  The Holders of not less than a majority in principal amount of
the Outstanding Securities may on behalf of the Holders of all the Securities
waive any past default hereunder and its consequences, except a default

                  (1) in the payment of the principal of or interest on any
         Security, or

                  (2) in respect of a covenant or provision hereof which under
         Article Nine cannot be modified or amended without the consent of the
         Holder of each Outstanding Security affected.

                  Upon any such waiver, such default shall cease to exist, and
any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.


SECTION 514.  Undertaking for Costs.

                  In any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in
such suit to file an undertaking to pay the costs of such suit, and may assess
costs against any such party litigant, in the manner and to the extent provided
in the Trust Indenture Act; provided, that neither this Section nor the Trust
Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Company
or in any suit for the


                                      -39-

enforcement of the right to convert any Security in accordance with Article
Twelve.


SECTION 515.  Waiver of Stay or Extension Laws.

                  The Company covenants (to the extent that it may lawfully do
so) that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law
wherever enacted, now or at any time hereafter in force, which may affect the
covenants or the performance of this Indenture; and the Company (to the extent
that it may lawfully do so) hereby expressly waives all benefit or advantage of
any such law and covenants that it will not hinder, delay or impede the
execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

otherwise incur any financial liability in the performance of any of its duties

relating to the conduct or affecting the liability of or affording protection to
the Trustee shall be subject to the provisions of this Section .

SECTION 611.  Acceptance of Appointment by Successor.

                  Every successor Trustee appointed hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting such appointment, and thereupon the resignation or removal of the
retiring Trustee shall become effective and such successor Trustee, without any
further act, deed or conveyance, shall become vested with all the rights,
powers, trusts and duties of the retiring Trustee; but, on request of the
Company or the successor Trustee, such retiring Trustee shall, upon payment of
its charges, execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign, transfer and deliver to such successor Trustee all property and money
held by such retiring Trustee hereunder. Upon request of any such successor
Trustee, the Company shall execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights,
powers and trusts.

                  No successor Trustee shall accept its appointment unless at

eligible under this Article.


SECTION 612.      Merger, Conversion, Consolidation or Succession to Business.

trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

SECTION 613. Preferential Collection of Claims Against Company.

                  If and when the Trustee shall be or become a creditor of the
Company (or any other obligor upon the Securities), the Trustee shall be subject
to the provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor).


SECTION 614. Appointment of Authenticating Agent.

                  The Trustee may appoint an Authenticating Agent or Agents
which shall be authorized to act on behalf of the Trustee to authenticate
Securities issued upon original issue and upon exchange, registration of
transfer or pursuant to Section 306, and Securities so authenticated shall be
entitled to the benefits of this Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section , the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section , such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section .

                  Any corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any corporation succeeding to the


                                      -47-
<PAGE>   58
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible under this Section , without the execution or filing of any
paper or any further act on the part of the Trustee or the Authenticating Agent.

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and to the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and to the Company. Upon receiving such a
notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section , the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders as their
names and addresses appear in the Security Register. Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of
this Section .

                  The Trustee agrees to pay to each Authenticating Agent from
time to time reasonable compensation for its services under this Section , and
the Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

                  If an appointment is made pursuant to this Section , the
Securities may have endorsed thereon, in addition to the Trustee's certificate
of authentication, an alternative certificate of authentication in the following
form:

                  This is one of the Securities described in the
within-mentioned Indenture.

interest on the Securities in accordance with the terms of the Securities and
this Indenture.


SECTION 1002.     Maintenance of Office or Agency.

                  The Company will maintain in the Borough of Manhattan, the
City of New York, New York an office or agency where Securities may be presented
or surrendered for payment, where Securities may be surrendered for registration
of transfer or exchange, where Securities may be surrendered for conversion and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served. The Company will give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency. If at any time the Company shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee as its agent to receive all such presentations, surrenders, notices and
demands.

                  The Company may also from time to time designate one or more
other offices or agencies (in or outside the

<PAGE>   66
Borough of Manhattan, the City of New York, New York) where the Securities may
be presented or surrendered for any or all such purposes and may from time to
time rescind such designations; provided, however, that no such designation or
rescission shall in any manner relieve the Company of its obligation to maintain
an office or agency in the Borough of Manhattan, the City of New York, New York
for such purposes. The Company will give prompt written notice to the Trustee of
any such designation or rescission and of any change in the location of any such
other office or agency.


SECTION 1003. Money for Security Payments to Be Held in Trust.

                  If the Company shall at any time act as its own Paying Agent,
it will, on or before each due date of the principal of or interest on any of
the Securities, segregate and hold in trust for the benefit of the Persons
entitled thereto a sum sufficient to pay the principal or interest so becoming
due until such sums shall be paid to such Persons or otherwise disposed of as
herein provided and will promptly notify the Trustee of its action or failure so
to act.

                  Whenever the Company shall have one or more Paying Agents, it
will, prior to each due date of the principal of or interest on any Securities,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be
held as provided by the Trust Indenture Act, and (unless such Paying Agent is
the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

                  The Company will cause each Paying Agent other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section ,
that such Paying Agent will (i) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (ii) during the continuance
of any default by the Company (or any other obligor upon the Securities) in the
making of any payment in respect of the Securities, upon the written request of
the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying
Agent as such.

                  The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be


                                      -56-
<PAGE>   67
held by the Trustee upon the same trusts as those upon which such sums were held
by the Company or such Paying Agent; and, upon such payment by any Paying Agent
to the Trustee, such Paying Agent shall be released from all further liability
with respect to such money.

                  Any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of or
interest on any Security and remaining unclaimed for two years after such
principal or interest has become due and payable shall be paid to the Company on
Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such
repayment, may at the expense of the Company cause to be published once, in a
newspaper published in the English language, customarily published on each
Business Day and of general circulation in the Borough of Manhattan, the City of
New York, New York, notice that such money remains unclaimed and that, after a
date specified therein, which shall not be less than 30 days from the date of
such publication, any unclaimed balance of such money then remaining will be
repaid to the Company.

                  Subject to Article Eight, the Company will do or cause to be
done all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and franchises; provided, however,

                           Subordination of Securities

SECTION 1101. Securities Subordinate to Senior Indebtedness.

                  The Company covenants and agrees, and each Holder of a
Security, by his acceptance thereof, likewise covenants and agrees, that, to the
extent and in the manner hereinafter set forth in this Article, the indebtedness
represented by the Securities and the payment of the principal of and interest
on each and all of the Securities are hereby expressly made subordinate and
subject in right of payment to the prior payment in full of all Senior
Indebtedness.


SECTION 1102. Payment Over of Proceeds Upon Dissolution, Etc.

                  In the event of (a) any insolvency or bankruptcy case or
proceeding, or any receivership, liquidation, reorganization or other similar
case or proceeding in connection therewith, relative to the Company or to its
creditors, as such, or to its assets, or (b) any liquidation, dissolution or
other winding up of the Company, whether voluntary or involuntary and whether or
not involving insolvency or bankruptcy, or (c) any assignment for the benefit of
creditors or any other marshalling of assets and liabilities of the Company,
then and in any such event the holders of Senior Indebtedness shall be entitled
to receive payment in full of all amounts due or to become due on or in respect
of all Senior Indebtedness, or provision shall be made for such payment in cash,
before the Holders of the Securities are entitled to receive any


                                      -58-
<PAGE>   69
payment on account of principal of or interest on the Securities, and to that
end the holders of Senior Indebtedness shall be entitled to receive, for
application to the payment thereof, any payment or distribution of any kind or
character, whether in cash, property or securities, which may be payable or
deliverable in respect of the Securities in any such case, proceeding,
dissolution, liquidation or other winding up or event.

                  In the event that, notwithstanding the foregoing provisions of
this Section , the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, before all Senior Indebtedness is paid
in full or payment thereof provided for, and if such fact shall, at or prior to
the time of such payment or distribution, have been made known to the Trustee
or, as the case may be, such Holder, then and in such event such payment or
distribution shall be paid over or delivered forthwith to the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other
Person making payment or distribution of assets of the Company for application
to the payment of all Senior Indebtedness remaining unpaid, to the extent
necessary to pay all Senior Indebtedness in full, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Indebtedness.

                  For purposes of this Article only, the words "cash, property
or securities" shall not be deemed to include shares of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment which are subordinated
in right of payment to all Senior Indebtedness which may at the time be
outstanding to substantially the same extent as, or to a greater extent than,
the Securities are so subordinated as provided in this Article. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the conveyance
or transfer of its properties and assets substantially as an entirety to another
Person upon the terms and conditions set forth in Article Eight shall not be
deemed a dissolution, winding up, liquidation, reorganization, assignment for
the benefit of creditors or marshalling of assets and liabilities of the Company
for the purposes of this Section if the Person formed by such consolidation or
into which the Company is merged or which acquires by conveyance or transfer
such properties and assets substantially as an entirety, as the case may be,


                                      -59-

shall, as a part of such consolidation, merger, conveyance or transfer, comply
with the conditions set forth in Article Eight.


SECTION 1103. Prior Payment to Senior Indebtedness Upon Acceleration of
Securities.

                  In the event that any Securities are declared due and payable
before their Stated Maturity, then and in such event the holders of the Senior
Indebtedness outstanding at the time such Securities so become due and payable
shall be entitled to receive payment in full of all amounts due or to become due
on or in respect of all Senior Indebtedness, or provision shall be made for such
payment in cash, before the Holders of the Securities are entitled to receive
any payment [(including any payment which may be payable by reason of the
payment of any other indebtedness of the Company being subordinated to the
payment of the Securities)](*) by the Company on account of the principal of or
interest on the Securities or on account of the purchase or other acquisition of
Securities.

                  In the event that, notwithstanding the foregoing, the Company
shall make any payment to the Trustee or the Holder of any Security prohibited
by the foregoing provisions of this Section , and if such fact shall, at or
prior to the time of such payment, have been made known to the Trustee or, as
the case may be, such Holder, then and in such event such payment shall be paid
over and delivered forthwith to the Company.

                  The provisions of this Section shall not apply to any payment
with respect to which Section 1102 would be applicable.


SECTION 1104. No Payment When Senior Indebtedness in Default.

                  (a) In the event and during the continuation of any default in
the payment of principal of or interest on any Senior Indebtedness beyond any
applicable grace period with respect thereto, or in the event that any event of
default with respect to any Senior Indebtedness shall have

*        This provision should be included if the Company may have a class or
         classes of debt which are subordinated to the Securities.

occurred and be continuing permitting the holders of such Senior Indebtedness
(or a trustee on behalf of the holders thereof) to declare such Senior
Indebtedness due and payable prior to the date on which it would otherwise have
become due and payable, unless and until such event of default shall have been
cured or waived or shall have ceased to exist and such acceleration shall have
been rescinded or annulled, or (b) in the event any judicial proceeding shall be
pending with respect to any such default in payment or event of default, then no
payment shall be made by the Company on account of principal of or interest on
the Securities or on account of the purchase or other acquisition of Securities.

                  In the event that, notwithstanding the foregoing, the Company
shall make any payment to the Trustee or the Holder of any Security prohibited
by the foregoing provisions of this Section , and if such fact shall, at or
prior to the time of such payment, have been made known to the Trustee or, as
the case may be, such Holder, then and in such event such payment shall be paid
over and delivered forthwith to the Company.

                  The provisions of this Section shall not apply to any payment
with respect to which Section 1102 would be applicable.


SECTION 1105. Payment Permitted If No Default.

                  Nothing contained in this Article or elsewhere in this
Indenture or in any of the Securities shall prevent [(a)] the Company, at any
time except during the pendency of any case, proceeding, dissolution,
liquidation or other winding up, assignment for the benefit of creditors or
other marshalling of assets and liabilities of the Company referred to in
Section 1102 or under the conditions described in Section 1103 or 1104, from
making payments at any time of principal of or interest on the Securities [, or
(b) the application by the Trustee of any money deposited with it hereunder to
the payment of or on account of the principal of or interest on the Securities
or the retention of such payment by the Holders, if, at the time of such
application by the Trustee, it did not have knowledge that such payment would
have been prohibited by the provisions of this Article].

SECTION 1106. Subrogation to Rights of Holders of Senior Indebtedness.

                  Subject to the payment in full of all Senior Indebtedness, the
Holders of the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the
provisions of this Article to the rights of the holders of such Senior
Indebtedness to receive payments and distributions of cash, property and
securities applicable to the Senior Indebtedness until the principal of and
interest on the Securities shall be paid in full. For purposes of such
subrogation, no payments or distributions to the holders of the Senior
Indebtedness of any cash, property or securities to which the Holders of the
Securities or the Trustee would be entitled except for the provisions of this
Article, and no payments pursuant to the provisions of this Article to the
holders of Senior Indebtedness by Holders of the Securities or the Trustee,
shall, as among the Company, its creditors other than holders of Senior
Indebtedness and the Holders of the Securities, be deemed to be a payment or
distribution by the Company to or on account of the Senior Indebtedness.


SECTION 1107. Provisions Solely to Define Relative Rights.

                  The provisions of this Article are and are intended solely for
the purpose of defining the relative rights of the Holders of the Securities on
the one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as among the Company, its creditors other than
holders of Senior Indebtedness and the Holders of the Securities, the obligation
of the Company, which is absolute and unconditional (and which, subject to the
rights under this Article of the holders of Senior Indebtedness, is intended to
rank equally with all other general obligations of the Company), to pay to the
Holders of the Securities the principal of and interest on the Securities as and
when the same shall become due and payable in accordance with their terms; or
(b) affect the relative rights against the Company of the Holders of the
Securities and creditors of the Company other than the holders of Senior
Indebtedness; or (c) prevent the Trustee or the Holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article of the holders
of Senior Indebtedness to receive cash, property and securities


                                      -62-
<PAGE>   73
otherwise payable or deliverable to the Trustee or such Holder.


SECTION 1108. Trustee to Effectuate Subordination.

                  Each holder of a Security by his acceptance thereof authorizes
and directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.


SECTION 1109. No Waiver of Subordination Provisions.

                  No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time in
any way be prejudiced or impaired by any act or failure to act on the part of
the Company or by any act or failure to act, in good faith, by any such holder,
or by any non-compliance by the Company with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof any such holder may have
or be otherwise charged with.

                  Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness, or otherwise amend or supplement in any manner Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.

SECTION 1110. Notice to Trustee.

                  The Company shall give prompt written notice to the Trustee of
any fact known to the Company which would prohibit the making of any payment to
or by the Trustee in respect of the Securities. Notwithstanding the provisions
of this Article or any other provision of this Indenture, the Trustee shall not
be charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee therefor; and,
prior to the receipt of any such written notice, the Trustee, subject to the
provisions of Section 601, shall be entitled in all respects to assume that no
such facts exist [; provided, however, that if the Trustee shall not have
received the notice provided for in this Section at least [to be discussed with
the Trustee] Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of or interest on any Security), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it within [to be discussed with the Trustee] Business
Days prior to such date].

                  Subject to the provisions of Section 601, the Trustee shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee
therefor) to establish that such notice has been given by a holder of Senior
Indebtedness (or a trustee therefor). In the event that the Trustee determines
in good faith that further evidence is required with respect to the right of any
Person as a holder of Senior Indebtedness to participate in any payment or
distribution pursuant to this Article, the Trustee may request such Person to
furnish evidence to the reasonable satisfaction of the Trustee as to the amount
of Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

SECTION 1111. Reliance on Judicial Order or Certificate of Liquidating Agent.

                  Upon any payment or distribution of assets of the Company
referred to in this Article, the Trustee, subject to the provisions of Section
601, and the Holders of the Securities shall be entitled to rely upon any order
or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of Securities, for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to this Article.


SECTION 1112. Trustee Not Fiduciary for Holders of Senior Indebtedness.

                  The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness and shall not be liable to any such holders
if it shall in good faith mistakenly pay over or distribute to Holders of
Securities or to the Company or to any other Person cash, property or securities
to which any holders of Senior Indebtedness shall be entitled by virtue of this
Article or otherwise.


SECTION 1113. Rights of Trustee as Holder of Senior Indebtedness; Preservation
of Trustee's Rights.

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article with respect to any Senior Indebtedness
which may at any time be held by it, to the same extent as any other holder of
Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of
any of its rights as such holder.

<PAGE>   76
                  Nothing in this Article shall apply to claims of, or payments
to, the Trustee under or pursuant to Section 607.


SECTION 1114. Article Applicable to Paying Agents.

                  In case at any time any Paying Agent other than the Trustee
shall have been appointed by the Company and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying Agent
within its meaning as fully for all intents and purposes as if such Paying Agent
were named in this Article in addition to or in place of the Trustee; provided,
however, that Section 1113 shall not apply to the Company or any Affiliate of
the Company if it or such Affiliate acts as Paying Agent.



                                 ARTICLE TWELVE

                            Conversion of Securities

SECTION 1201. Terms of Conversion and Settlement.

At any time not more than 20 Trading Days nor fewer than two Trading Days
immediately prior to, but not including, the Conversion Date, any Holder may
elect (a "Conversion Election"), by written notice to the Trustee, to convert a
Security on the Conversion Date, into the right to receive in respect of each
Security the sum of (i) the Conversion Amount (as defined below) payable at the
Company's option in either Common Shares or in cash, plus (ii) the Additional
Amount (as defined below) payable in cash. Any Holder who does not make a timely
Conversion Election shall receive on the Conversion Date, in lieu of the
Conversion Amount and the Additional Amount and in full satisfaction of the
Holder's Securities, the principal sum of $_______ dollars in cash for each
Security. The Company will mail written notice of its election to pay the
Conversion Amount in either Common Shares or cash to each holder of record of
Convertible Notes not less than 30 Trading Days nor more than 45 Trading Days
prior to the Conversion Date and will include with such notice a description of
the procedure for making a Conversion Election. The "Conversion Amount" means an
amount (payable in either Common Shares or cash) for each Security equal to the
Current Market Price of Common Shares multiplied by the product of (x) .995 and
(y) the Convertible Note Exchange Rate. The Convertible Note Exchange Rate is
equal to (a) if the Current Market Price of the Common Shares is greater than or
equal to $_______ per share (the "Threshold Price"), a ratio equal to the
Threshold Price divided by the Current Market Price,


                                      -66-
<PAGE>   77
(b) if the Current Market Price is less than the Threshold Price but greater
than the Initial Price, a ratio of 1.0, and (c) if the Current Market Price is
less than or equal to the Initial Price, a ratio equal to the Initial Price
divided by the Current Market Price, subject in each case to adjustments in
certain events. The "Additional Amount" means an amount (payable in cash) in
respect of each Security equal to [$ Equal to .005 of Initial Price of the
Common Share].

                  The Convertible Note Exchange Rate is subject to adjustment as
appropriate in certain circumstances, including if the Company (a) pays a share
dividend or makes a distribution with respect to its Common Shares in Common
Shares, (b) subdivides or splits its outstanding Common Shares, (c) combines its
outstanding Common Shares into a smaller number of shares, (d) issues by
reclassification of its Common Shares any capital shares , (e) issues certain
rights or warrants to all holders of its Common Shares or (f) pays a dividend
of, or distributes to all holders of its Common Shares, evidences of its
indebtedness or other assets (including capital shares of the Company but
excluding any cash dividends or distributions and dividends referred to in
clause (a) above). In addition, the Company will be entitled to make such upward
adjustments in the Convertible Note Exchange Rate as the Company, in its
discretion, determines to be advisable, in order that any share dividend,
subdivision of shares, distribution of rights to purchase shares or securities,
or distribution of securities convertible into or exchangeable for shares (or
any transaction which could be treated as any of the foregoing transactions
pursuant to Section 305 of the Internal Revenue Code of 1986, as amended)
hereafter made by the Company to its shareholders will not be taxable. All
adjustments to the Convertible Note Exchange Rate will be calculated to the
nearest 1/10,000th of a Common Share. No adjustment in the Convertible Note
Exchange Rate will be required unless such adjustment would require an increase
or decrease of at least one percent in the Convertible Note Exchange Rate,
provided that any adjustments which, by reason of the foregoing, are not
required to be made shall be carried forward and taken into account in any
subsequent adjustment. All adjustments will be made successively. All
adjustments to the Convertible Note Exchange Rate shall be made consistent with
the provisions of paragraphs (d) and (f) of Section 4.4.3 of the Restated
Articles of Incorporation of the Company dated ________, 199_, treating the
Securities in the same manner as the Series A Preferred Shares for which they
were exchanged.


                                      -67-
<PAGE>   78
                  Whenever the Convertible Note Exchange Rate is adjusted as
provided in the preceding paragraph, the Company will file with the Trustee a
certificate with respect to such adjustment, make a prompt public announcement
thereof and mail a notice to Holders providing specified information with
respect to such adjustment.


                  The Company will reserve and at all times keep available, free
from preemptive rights, out of its authorized but unissued shares, for the
purpose of effecting the conversion of the Securities, such number of its duly
authorized Common Shares as will from time to time be sufficient to effect the
conversion of all outstanding Securities; provided, however, that the Company
shall not be obligated to keep such shares available with respect to any
Securities during any time that the conversion of such Securities is prohibited
under a contract or other agreement between the holder of such Securities and
the Company.

                  The Company will mail written notice of its election to pay
the Conversion Amount in either Common Shares or cash to each Holder of record
of Securities not less than 30 Trading Days nor more than 45 Trading Days prior
to the Conversion Date. In the case of election by the Company to pay the
Conversion Amount in Common Shares the Company will issue the number of full
shares of Common Shares issuable in payment thereof. No fractional Common Shares
will be issued on payment of the Conversion Amount, but in lieu thereof, such
fractional interest shall be rounded down to the next whole share and an amount
will be paid in cash by the Company for such fractional interest based upon the
Current Market Price.

SECTION 1202.  Merger Adjustments

                  In case of any consolidation or merger to which the Company is
a party (other than a merger or consolidation in which the Company is the
continuing corporation and in which the Common Shares outstanding immediately
prior to the merger or consolidation remain unchanged), or in case of any sale
or transfer to another entity of the property of the Company as an entirety or
substantially as an entirety, or in case of any statutory share exchange with
another entity (other than in connection with an acquisition in which the Common
Shares outstanding immediately prior to the share exchange remain unchanged),
each Security shall, after consummation of such transaction, be subject to (i)
conversion at the option of the holder into the kind and


                                      -68-
<PAGE>   79
amount of securities, cash, or other property receivable upon consummation of
such transaction by a holder of the number of Common Shares into which such
Securities might have been converted immediately prior to consummation of such
transaction and (ii) conversion on the Conversion Date into the kind and amount
of securities, cash, or other property receivable upon consummation of such
transaction by a holder of the number of Common Shares into which such Security
would have been converted if the conversion on the Conversion Date had occurred
immediately prior to the date of consummation of such transaction assuming in
each case that such holder of Common Shares failed to exercise rights of
election if any, as to the kind or amount of securities, cash, or other property
receivable upon consummation of such transaction (provided that if the kind or
amount of securities, cash, or other property receivable upon consummation of
such transaction is not the same for each nonelecting share, then the kind and
amount of securities, cash, or other property receivable upon consummation of
such transaction for each nonelecting share shall be deemed to be the kind and
amount so receivable per share by a plurality of the nonelecting shares). The
kind and amount of securities into which the Securities shall be convertible
after consummation of such transaction shall be subject to adjustment as
described above under Section 1201 following the date of consummation of such
transaction. The Company may not become a party to any such transaction unless
the terms thereof are consistent with the foregoing.



                  This instrument may be executed in any number of counterparts,
each of which so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

                  IN WITNESS WHEREOF, the parties hereto have caused this
Indenture to be duly executed, and their respective corporate seals to be
hereunto affixed and attested, all as of the day and year first above written.

      Re:  Registration Statement on Form S-3 of Microsoft Corporation

Ladies and Gentlemen:

         We have acted as counsel to Microsoft Corporation (the "Company") in
connection with the filing of the above-referenced Registration Statement (the
"Registration Statement") relating to the offer of % Convertible Exchangeable
Principal-Protected Preferred Shares, Series A, par value $0.01 per share (the
"Series A Preferred Shares"), and the % Convertible Subordinated Notes Due 1999
(the "Convertible Notes") and the Common Shares, par value $0.000025 per share
(the "Common Shares" and, together with the Series A Preferred Shares and the
Convertible Notes, the "Securities") issuable upon conversion of the Series A
Preferred Shares or the Convertible Notes. In connection therewith, we have
reviewed the Company's Restated Articles of Incorporation, Bylaws, resolutions
of the Company's Board of Directors, the Indenture under which the Convertible
Notes will be issued (the "Indenture"), and such other documents and matters we
deemed appropriate.

         In connection with this opinion, we have assumed that (i) the
Registration Statement, and any amendments thereto (including post-effective
amendments), will have become effective, and (ii) all Securities will be issued
and sold in compliance with applicable federal and state securities laws and in
the manner stated in the Registration Statement.

         Based on this review, it is our opinion that:

         1. The Series A Preferred Shares have been duly authorized and, when
securities representing the Series A Preferred Shares shall have been duly
executed, authenticated, issued and delivered to the recipients thereof upon
payment of consideration therefor, will be legally issued, fully paid and
non-assessable.

         2. The Convertible Notes have been duly authorized and, when securities
representing the Convertible Notes shall have been duly executed, authenticated,
issued and delivered to the recipients thereof in accordance with the terms of
the Indenture and upon exercise of the Company's right of exchange pursuant to
the Series A Preferred Shares, will be legally issued, fully paid,
non-assessable and binding obligations of the Company and will be

Page 2




enforceable against the Company in accordance with their terms, except as
enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
fraudulent conveyance and other similar laws affecting the enforcement of
creditors' rights generally and except as enforcement thereof is subject to
general principles of equity (regardless of whether enforcement is considered in
a proceeding in equity or at law).

         3. The Common Shares have been duly authorized and, when securities
representing the Common Shares shall have been duly executed, authenticated,
issued and delivered to the recipients thereof upon conversion of the Series A
Preferred Shares or the Convertible Notes, will be legally issued, fully paid
and non-assessable.

         We do not find it necessary for the purposes of this opinion to cover,
and accordingly we express no opinion as to, the application of the securities
or blue sky laws of the various states to the sale of the Convertible Notes.

         This opinion letter is limited to the matters stated herein and no
opinion is implied or may be inferred beyond the matters expressly stated.

         This letter speaks only as of the date hereof and is limited to present
statutes, regulations and administrative and judicial interpretations. We
undertake no responsibility to update or supplement this letter after the date
hereof.

         We consent to being named in the Registration Statement and related
Prospectus as counsel who are passing upon the validity of the Securities for
the Company and to the reference to our name under the caption "Validity of
Securities" in such Prospectus. We further consent to your filing copies of this
opinion as an exhibit to the Registration Statement or any amendment thereto. In
giving such consents, we do not hereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act.

                                                     Very truly yours,

Commission in connection with the proposed sale by Microsoft Corporation of

Shares.

Ellis under the caption "Certain U.S. Federal Income Tax Considerations" in the
Prospectus that is part of the Registration Statement.

*    Not meaningful
(1)  The Company had no material debt and, consequently, had no material fixed
     charges for each of the periods presented. The ratio of earnings to fixed
     charges is determined by dividing earnings by fixed charges. Fixed charges
     consist of the total of (i) interest, whether expensed or capitalized; (ii)
     amortization of debt expense and discount or premium relating to any
     indebtedness, whether expensed or capitalized; (iii) such portion of rental
     expense as can be demonstrated to be representative of the interest factor
     in the particular case; and (iv) preferred stock dividend requirements of
     majority-owned subsidiaries and fifty-percent-owned persons, excluding in
     all cases items which would be or are eliminated in consolidation. Earnings
     consist of pretax income from continuing operations plus the amount of
     fixed charges, adjusted to exclude (i) the amount of any interest
     capitalized during the period and (ii) the actual amount of any preferred
     stock dividend requirements of majority-owned subsidiaries and
     fifty-percent-owned persons which were included in such fixed charges
     amount but not deducted in the determination of pretax income. The ratio of
     earnings to fixed charges is not meaningful for periods in which there were
     no material fixed charges.
