EVEREN SECURITIES, INC.  
77 West Wacker Drive      
Chicago, Illinois 60601  
 
  The undersigned, Kilroy Realty Corporation, a Maryland corporation (the
"Company"), the sole general partner and a limited partner of Kilroy Realty,
L.P., a Delaware limited partnership (the "Operating Partnership"), hereby
confirms its agreement with you (the "Underwriter") as follows:
 
  1. Description of Shares. The Company proposes to issue and sell to you
546,697 shares (the "Shares") of its common stock, par value $.01 per share (the
"Common Stock"). The Shares are more fully described in the Prospectus
hereinafter defined.
 
  2. Purchase, Sale and Delivery of Shares. On the basis of the
representations, warranties and agreements herein contained, but subject to
the terms and conditions herein set forth, the Company agrees to sell to you,
and you agree to purchase from the Company at a purchase price of $26.0656 per
share, the Shares.
 
  The Company will deliver definitive certificates for the Shares at the office
of Everen Securities, Inc., New York, New York ("Everen's Office"), or such
other place as you and the Company may mutually agree upon (the "Place of
Closing"), for your account against payment to the Company of the purchase price
for the Shares sold to you by wire transfer of immediately available funds, at
10:00 a.m., Chicago time, on March 30, 1998, or at such other time and date not
later than three full business days thereafter as you and the Company may agree,
such time and date of payment and delivery being herein called the "Closing
Date."

  The certificates for the Shares so to be delivered will be made available to
you for inspection at Everen's Office (or such other place as you and the
Company may mutually agree upon) at least one full business day prior to the
Closing Date and will be in such names and denominations as you may request at
least one full business day prior to the Closing Date.
 
  3. Representations, Warranties and Agreements of the Company and the
Operating Partnership. The Company and the Operating Partnership, jointly and
severally, represent and warrant to and agree with you that:
 
    (a) The Company meets the requirements for use of Form S-3 under the
  Securities Act of 1933, as amended (the "Act"); a registration statement
  (Registration No. 333-45097) on Form S-3, including a prospectus relating
  to the registration of the Shares and such other securities which may be
  offered from time to time in accordance with Rule 415 under the Act, and
  such amendments to such registration statement as may have been required to
  the date of this Agreement, has been prepared by the Company and the
  Operating Partnership pursuant to and in conformity with the requirements
  of the Act, and the Rules and Regulations (the "Rules and Regulations") of
  the Securities and Exchange Commission (the "Commission") thereunder, was
  filed with the Commission under the Act and was declared effective on
  February 11, 1998. Copies of such registration statement, including any
  amendments thereto, each related preliminary prospectus contained therein,
  the exhibits, financial statements and schedules have heretofore been
  delivered by the Company to you. A prospectus supplement (the "Prospectus
  Supplement") setting forth the terms of the offering, sale and plan of
  distribution of the Shares and additional information concerning the
  Company, the Operating Partnership and their subsidiaries (the
  "Subsidiaries") and their business has been or will be so prepared and will
  be filed pursuant to Rule 424(b) of the Rules and
<PAGE>
 
  Regulations on or before the second business day after the date hereof (or
  such earlier time as may be required by the Rules and Regulations). The
  term "Registration Statement" as used herein means the registration
  statement, and the base prospectus included therein, as amended at the time
  it or any amendment thereto became effective under the Act, or at any time
  any Annual Report on Form 10-K is filed by the Company with the Commission
  (the "Effective Date"), including financial statements and all exhibits and
  all documents incorporated by reference therein pursuant to Item 12 of Form
  S-3 under the Act. Any document filed by the Company under the Securities
  Exchange Act of 1934, as amended (the "Exchange Act") after the effective
  date of the Registration Statement or the date of the Prospectus Supplement
  and incorporated by reference in the Prospectus shall be deemed to be
  included in the Registration Statement and the Prospectus as of the date of
  such filing. The term "Prospectus" as used herein means (i) the base
  prospectus included in the Registration Statement at the Effective Date, as
  supplemented by the Prospectus Supplement as first filed with the
  Commission pursuant to Rule 424(b) of the Rules and Regulations, except
  that, if such base prospectus is amended or supplemented subsequent to the
  Effective Date, the term "Prospectus" shall refer to the base prospectus as
  so amended or supplemented and as further supplemented by the Prospectus
  Supplement, (ii) if no such filing is required, the form of final
  prospectus included in the Registration Statement at the Effective Date or
  (iii) if a Term Sheet or Abbreviated Term Sheet (as such terms are defined
  in Rule 434(b) and 434(c), respectively, of the Rules and Regulations) is
  filed with the Commission pursuant to Rule 424(b)(7) of the Rules and
  Regulations, the Term Sheet or Abbreviated Term Sheet and the last
  Preliminary Prospectus filed with the Commission prior to the time the
  Registration Statement became effective, taken together (including, in each
  case, the documents incorporated by reference therein pursuant to Item 12
  of Form S-3 under the Act). The term "Preliminary Prospectus" as used
  herein shall mean a preliminary prospectus included at any time in the
  Registration Statement.
 
    (b) The Commission has not issued, and is not to the knowledge of the
  Company or the Operating Partnership threatening to issue, an order
  preventing or suspending the use of any Preliminary Prospectus or the
  Prospectus nor instituted proceedings for that purpose. Each Preliminary
  Prospectus at its date of issue, the Registration Statement at the
  Effective Date, and the Prospectus at its date of issue and any amendments
  or supplements thereto contained, as the case may be, all statements which
  are required to be stated therein by, and in all material respects conform
  or will conformed to the requirements of, the Act and the Rules and
  Regulations. Neither the Registration Statement nor any amendment thereto,
  as of the applicable effective date, and neither the Prospectus nor any
  supplement thereto, as of its applicable issue date or the Closing Date,
  contained any untrue statement of a material fact or omitted to state any
  material fact required to be stated therein or necessary to make the
  statements therein, in the light of the circumstances under which they were
  made, not misleading; provided, however, that the Company and the Operating
  Partnership make no representation or warranty as to information contained
  in or omitted from the Registration Statement or the Prospectus, or any
  such amendment or supplement, in reliance upon, and in conforming with,
  written information furnished to the Company by you specifically for use in
  the preparation thereof.
 
    (c) The documents incorporated by reference in the Prospectus pursuant to
  Item 12(a) of Form S-3 under the Act, at the time they were filed with the
  Commission, complied in all material respects with the requirements of the
  Exchange Act, and the rules and regulations adopted by the Commission
  thereunder (the "1934 Act Rules and Regulations"), and, when read together
  and with the other information in the Prospectus, at the time the
  Registration Statement became effective did not contain an untrue statement
  of a material fact or omit to state a material fact required to be stated
  therein or necessary to make the statements therein not misleading.
 
    (d) The filing of the Registration Statement and the execution and
  delivery of this Agreement by the Company and the Operating Partnership
  have been duly authorized by the Board of Directors of the Company; this
  Agreement constitutes a valid and legally binding obligation of the Company
  and the Operating Partnership enforceable in accordance with its terms
  (except to the extent the enforceability of the indemnification and
  contribution provisions of Section 6 hereof may be limited by public policy
  considerations as expressed in the Act as construed by courts of competent
  jurisdiction, and except as enforceability may be limited by bankruptcy,
  insolvency, reorganization, moratorium and other laws

  affecting creditors' rights generally and by general principles of equity);
  the issue and sale of the Shares by the Company and the performance of this
  Agreement and the consummation of the transactions herein contemplated will
  not result in a violation of the Company's articles of incorporation or
  bylaws or the Operating Partnership's Second Amended and Restated Agreement
  of Limited Partnership, each as amended, or result in a breach or violation
  of any of the terms and provisions of, or constitute a default under, or
  result in the creation or imposition of any lien, charge or encumbrance
  upon any properties or assets of the Company, the Operating Partnership or
  the Subsidiaries under, any statute, or under any indenture, mortgage, deed
  of trust, note, loan agreement, sale and leaseback arrangement or other
  agreement or instrument to which any of the Company, the Operating
  Partnership or the Subsidiaries is a party or by which they are bound or to
  which any of the properties or assets of the Company, the Operating
  Partnership or the Subsidiaries is subject, or any order, rule or
  regulation of any court or governmental agency or body having jurisdiction
  over the Company, the Operating Partnership or the Subsidiaries or their
  properties, except in each case for such violations and breaches which
  would not reasonably be expected to, individually or in the aggregate,
  materially adversely affect the condition (financial or other), net worth,
  business, affairs, management or results of operations of the Company, the
  Operating Partnership and the Subsidiaries taken as a whole; no consent,
  approval, authorization, order, registration or qualification of or with
  any court or governmental agency or body is required for the consummation
  of the transactions herein contemplated, except such as may be required by
  the National Association of Securities Dealers, Inc. (the "NASD") or under
  the Act or Rules and Regulations or any state securities laws.
 
    (e) None of the Company, the Operating Partnership or any of the
  Subsidiaries has sustained since the date of the latest audited financial
  statements included or incorporated by reference in the Prospectus any
  material 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. Except as
  described in or as contemplated in the Prospectus, subsequent to the
  respective dates as of which information is given in the Registration
  Statement and the Prospectus, the Company, the Operating Partnership and
  the Subsidiaries taken as a whole have not incurred any material
  liabilities or material obligations, direct or contingent, other than in
  the ordinary course of business, or entered into any material transactions
  not in the ordinary course of business, and there has not been any material
  change in the capital stock or long-term debt of the Company and the units
  of partnership interest (the "Units") or long-term debt of the Operating
  Partnership and the Subsidiaries taken as a whole or any material adverse
  change in the condition (financial or other), net worth, business, affairs,
  management, or results of operations of the Company, the Operating
  Partnership and the Subsidiaries taken as a whole. The Company, the
  Operating Partnership and the Subsidiaries have filed all required federal,
  state and foreign income and franchise tax returns and paid all taxes shown
  as due thereon except in any case in which the failure so to file would not
  reasonably be excepted to, individually or in the aggregate, materially
  adversely affect the condition (financial or other), net worth, business,
  affairs, management or results of operations of the Company, the Operating
  Partnership and the Subsidiaries, taken as a whole; all tax liabilities are
  adequately provided for on the books of the Company, the Operating
  Partnership and the Subsidiaries except to such extent as would not
  reasonably be expected to materially adversely affect the condition
  (financial or other), net worth, business, affairs, management or results
  of operations of the Company, the Operating Partnership and the
  Subsidiaries taken as a whole; the Company, the Operating Partnership and
  the Subsidiaries have made all required payroll tax payments except for any
  such payment that is currently being contested in good faith or the
  nonpayment of which would otherwise not reasonably be excepted to,
  individually or in the aggregate, materially adversely affect the condition
  (financial or other), net worth, business, affairs, management or results
  of operations of the Company, the Operating Partnership and the
  Subsidiaries, taken as a whole as of the date of this Agreement; and the
  Company, the Operating Partnership and the Subsidiaries have no knowledge
  of any tax proceeding or action pending or threatened against the Company,
  the Operating Partnership or the Subsidiaries which would not reasonably be
  excepted to, individually or in the aggregate, materially adversely affect
  the condition (financial or other), net worth, business, affairs,
  management or results of operations of the Company, the Operating
  Partnership and the Subsidiaries, taken as a whole.
 
                                      -3-
<PAGE>
 
    (f) Except as described in the Prospectus, there is not now pending or,
  to the knowledge of the Company or the Operating Partnership, threatened or
  contemplated, any action, suit or proceeding to which any of the Company,
  the Operating Partnership or the Subsidiaries is a party before or by any
  court or public, regulatory or governmental agency or body which would
  reasonably be excepted to, individually or in the aggregate, materially
  adversely affect the condition (financial or other), net worth, business,
  affairs, management or results of operations of the Company, the Operating
  Partnership and the Subsidiaries, taken as a whole, and there are no
  contracts or documents of the Company, the Operating Partnership and the
  Subsidiaries which would be required to be filed as exhibits to the
  Registration Statement by the Act or by the Rules and Regulations which
  have not been filed as exhibits to the Registration Statement or
  incorporated by reference therein.
 
    (g) The Company has duly and validly authorized capital stock as
  described in the Prospectus; all outstanding shares of capital stock of the
  Company conform, and the Shares when issued will conform, to the
  description thereof in the Prospectus and have been, or, when issued and
  paid for will be, duly authorized, validly issued, fully paid and
  nonassessable; and the issuance of the Shares to be purchased from the
  Company hereunder is not subject to preemptive rights.
 
    (h) Each of the Company, the Operating Partnership and the Subsidiaries
  have been duly incorporated or formed, as the case may be, and is a validly
  existing corporation or limited partnership, as the case may be, in good
  standing under the laws of the state or other jurisdiction in which it is
  incorporated or formed, as the case may be. The Company, the Operating
  Partnership and the Subsidiaries have full power and authority (corporate
  and other) to own, lease and operate their properties and conduct their
  businesses as described in the Prospectus; each of the Company, the
  Operating Partnership and the Subsidiaries is duly qualified or registered
  to do business and is in good standing in each state or other jurisdiction
  in which its ownership or leasing of property or conduct of business
  legally requires such qualification, except where the failure to be so
  qualified would not have a material adverse effect on the ability of the
  Company and the Operating Partnership to conduct its or their business as
  described in the Prospectus; and the outstanding shares of capital stock or
  ownership interests of the Subsidiaries have been duly authorized and
  validly issued, are, in the case of shares of capital stock, fully paid and
  nonassessable and are owned by the Company or Operating Partnership, as the
  case may be, free and clear of any mortgage, pledge, lien, encumbrance,
  charge or adverse claim.
 
    (i) Deloitte & Touche LLP, the accounting firm which has certified the
  financial statements filed with or incorporated by reference in and as a
  part of the Registration Statement, is an independent public accounting
  firm within the meaning of the Act and the Rules and Regulations.
 
    (j) The consolidated financial statements of the Company together with
  the related schedules and notes thereto, set forth or included or
  incorporated by reference in the Registration Statement and Prospectus
  fairly present the consolidated financial condition of the Company as of
  the dates indicated and the consolidated results of operations,
  shareholders' equity and cash flows for the periods therein specified, in
  conformity with generally accepted accounting principles consistently
  applied throughout the periods involved (except as otherwise stated
  therein). The summary and selected financial and statistical data included
  or incorporated by reference in the Registration Statement and the
  Prospectus present fairly the information shown therein and, to the extent
  based upon or derived from the financial statements, have been compiled on
  a basis consistent with the financial statements presented therein. In
  addition, the pro forma financial statements of the Company, and the
  related notes thereto, included or incorporated by reference in the
  Registration Statement and the Prospectus present fairly the information
  shown therein, have been prepared in accordance with the Commission's rules
  and guidelines with respect to pro forma financial statements and have been
  compiled on the basis described therein, and the assumptions used in the
  preparation thereof are reasonable and the adjustments used therein are
  appropriate to give effect to the transactions and circumstances referred
  to therein. Furthermore, all financial statements required by Rule 3-14 of
  Regulation S-X ("Rule 3-14") have been included or incorporated by
  reference in the Registration Statement and the Prospectus and any such
  financial statements are in conformity with the requirements of Rule 3-14.
  No other financial statements are required to be set forth or to be
  incorporated by reference in the Registration Statement or the Prospectus
  under the Act or the Rules and Regulations thereunder.

    (k) None of the Company, the Operating Partnership or any of the
  Subsidiaries is in default with respect to any contract or agreement to
  which it is a party except for such defaults which would not reasonably be
  excepted to, individually or in the aggregate, materially adversely affect
  the condition (financial or other), net worth, business, affairs,
  management or results of operations of the Company, the Operating
  Partnership and the Subsidiaries, taken as a whole.
 
    (l) None of the Company, the Operating Partnership or the Subsidiaries is
  in violation of any other laws, ordinances or governmental rules or

  Prospectus, the name of the Underwriter, the price at which the Shares are
  to be purchased by the Underwriter from the Company and such other
  information as the Underwriter and the Company deem appropriate in
  connection with the offering of the Shares, and file the Prospectus in a
  form approved by you pursuant to Rule 424(b) under the Act no later than
  the Commission's close of business on the second business day following the
  date of the determination of the offering price of the Shares; (ii) not
  file (and the Operating Partnership will not so file) any amendment to the

  not previously have been advised and furnished with a copy or to which you
  shall have reasonably objected in writing or which is not in compliance
  with the Rules and Regulations; and (iii) promptly notify you after it
  shall have received notice thereof of the time when any amendment to the
  Registration Statement becomes effective or when any supplement to the
  Prospectus has been filed.
 
    (b) The Company or the Operating Partnership, as the case may be, will
  advise you promptly, after it shall receive notice or obtain knowledge
  thereof, of any request of the Commission for amendment of the Registration

  of the Registration Statement or the use of the Prospectus or of the
  institution or threatening of any proceedings for that purpose, and the
  Company and the Operating Partnership will use their best efforts to
  prevent the issuance of any such stop order preventing or suspending the
  use of the Prospectus and to obtain as soon as possible the lifting
  thereof, if issued.
 
    (c) The Company will cooperate with you and your counsel in endeavoring
  to qualify the Shares for sale under the securities laws of such
  jurisdictions as you may have designated and will make such applications,
  file such documents, and furnish such information as may be necessary for
  that purpose, provided the Company shall not be required to qualify as a
  foreign corporation or to file a general consent to service of process in
  any jurisdiction where it is not now so qualified or required to file such
  a consent or to subject itself to taxation as doing business in any
  jurisdiction where it is not now so taxed. The Company will, from time to
  time, file such statements, reports, and other documents, as are or may be

  by you, both in connection with the offering or sale of the Shares and for
  such other purposes and for such period of time thereafter as the
  Prospectus is required by law to be delivered in connection with the
  offering or sale of the Shares. The Company will deliver to you at or
  before the Closing Date two conformed copies of the Registration Statement
  and all amendments thereto including all exhibits filed therewith or

  of the Registration Statement, without exhibits, and of all amendments
  thereto, as you may reasonably request.
 
    (e) If, during the period in which a prospectus is required by law to be
  delivered by an underwriter or dealer, any event shall occur as a result of
  which, in the judgment of the Company or in your judgment or in the opinion
  of your counsel, it becomes necessary to amend or supplement the Prospectus
  in order to make the statements therein, in light of the circumstances
  existing at the time the Prospectus is delivered to a purchaser, not
  misleading, or, if it is necessary at any time to amend or supplement the
  Prospectus to comply with any applicable law, the Company promptly will
  prepare and file with the Commission an appropriate amendment to the
  Registration Statement or supplement to the Prospectus so that the
  Prospectus as so amended or supplemented will not, in the light of the
  circumstances when it is so delivered, be misleading, or so that the
  Prospectus will comply with such law.
 
    (f) The Company will make generally available to its shareholders and
  will file as an exhibit in a report pursuant to the Exchange Act, as soon
  as it is practicable to do so, but in any event not later than 15 months
  after the effective date of the Registration Statement, an earnings
  statement in reasonable detail, covering a period of at least 12
  consecutive months beginning after the effective date of the Registration
  Statement, which earnings statement shall satisfy the requirements of
  Section 11(a) of the Act and Rule 158 of the Rules and Regulations and will
  advise you in writing when such statement has been so made available.
 
    (g) The Company will apply the proceeds from the sale of the Shares as
  set forth in the description under "Use of Proceeds" in the Prospectus,
  which description complies in all respects with the requirements of Item
  504 of Regulation S-K.
 
    (h) The Company will supply you with copies of all correspondence to and
  from, and all documents issued to and by, the Commission in connection with
  the registration of the Shares under the Act.

    (j) Prior to the Closing Date, the Company will notify you in advance of
  any press conferences, releases or other communications, to be held or
  issued by the Company, with respect to the Company or any of its
  subsidiaries, the financial condition, results of operations, business,
  properties, assets or liabilities of the Company or any of its
  subsidiaries, or the offering of the Shares.
 
    (k) The Company will use its best efforts to obtain approval for, and
  maintain the listing of the Shares on, the New York Stock Exchange.

  delivered by an Underwriter or dealer, the Company will promptly file all
  documents required to be filed with the Commission pursuant to Sections 13,
  14 or 15(d) of the Exchange Act.
 
    (n) The Company will continue to elect to qualify as a "real estate
  investment trust" under the Code, and will use its best efforts to continue

basis for all reasonable legal and other expenses incurred pursuant to Section
6(c) hereof in connection with investigating or defending any such claim,
action, investigation, inquiry or other proceeding, notwithstanding the
absence of a judicial determination as to the propriety and enforceability of
the obligation of the Company and the Operating Partnership to reimburse you
for such expenses and the possibility that such payments might later be held
to have been improper by a court of competent jurisdiction. This indemnity
agreement shall be in addition to any liabilities which the Company and the
Operating Partnership may otherwise have.
 
  (b) You will indemnify and hold harmless the Company and the Operating
Partnership, each of its directors, each of its officers who have signed the
Registration Statement and each person, if any, who controls the Company or
the Operating Partnership within the meaning of the Act, against any losses,
claims, damages or liabilities, joint or several, to which the Company, the
Operating Partnership or any such director, officer or controlling person 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 any untrue statement or alleged untrue statement of any material
fact contained in the Registration Statement, any Preliminary Prospectus, the
Prospectus, any amendment or supplement thereto, or any Blue Sky Application
or arise out of or are based upon the omission or the alleged omission to
state therein a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they
were made, 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 the Registration Statement, such Preliminary Prospectus
or the Prospectus, such amendment or supplement, or any Blue Sky Application
in reliance upon and in conformity with written information furnished to the
Company by you specifically for use in the preparation thereof; and will
reimburse any legal or other expenses reasonably incurred by the Company, the
Operating Partnership or any such director, officer or controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action. In addition to your other obligations under this Section
6(b), you agree that, as an interim measure during the pendency of any claim,
action, investigation, inquiry or other proceeding arising out of or based
upon any statement or omission, or any alleged statement or omission,
described in this Section 6(b), you will reimburse the Company and the
Operating Partnership on a monthly basis for all reasonable legal and other
expenses incurred pursuant to Section 6(c) hereof in connection with
investigating or defending any such claim, action, investigation, inquiry or
other proceeding, notwithstanding the absence of a judicial determination as
to the propriety and enforceability of your obligation to reimburse the
Company and the Operating Partnership for such expenses and the possibility
that such payments might later be held to have been improper by a court of
competent jurisdiction. This indemnity agreement shall be in addition to any
liabilities which you may otherwise have.
 
  (c) Any party which proposes to assert the right to be indemnified under
this Section 6 shall, within ten days after receipt of notice of commencement
of any action, suit or proceeding against such party in respect of which a
claim is to be made against an indemnifying party under this Section 6, notify
each such indemnifying party of the commencement of such action, suit or
proceeding, enclosing a copy of all papers served, but the omission so to
notify such indemnifying party of any such action, suit or proceeding shall
not relieve such indemnifying party from any liability which it may have to
any indemnified party otherwise than under this Section 6. In case any such
action, suit or proceeding 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 in, and, to the extent
that it shall wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel reasonably satisfactory
to such indemnified 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 such indemnified party for any legal
or other expenses, other than reasonable costs of investigation, subsequently
incurred by such indemnified party in connection with the defense thereof. The
indemnified party shall have the right to employ its own counsel in any such
action, but the fees and expenses of such counsel shall be at the expense of
such indemnified party (it being understood, however, that in connection with
such action the indemnifying party shall not be liable for the expenses of
more than one separate counsel (in addition to local counsel) in any one
action or separate but substantially similar actions in the same jurisdiction
arising our of the same general allegations or circumstances) unless (i) the
employment of counsel by such indemnified
 
                                     -12-
<PAGE>
 
party at the expense of the indemnifying party has been authorized by the
indemnifying party, (ii) the indemnified party shall have been advised by such
counsel in a written opinion that there may be a conflict of interest between
the indemnifying party and the indemnified party in the conduct of the
defense, or certain aspects of the defense, of such action (in which case the
indemnifying party shall not have the right to direct the defense of such
action with respect to those matters or aspects of the defense on which a
conflict exists or may exist on behalf of the indemnified party) or (iii) the
indemnifying party shall not in fact have promptly employed counsel to assume
the defense of such action, in any of which events such fees and expenses to
the extent applicable shall be borne by the indemnifying party. An
indemnifying party shall not be liable for any settlement of any action or
claim effected without its consent. Each indemnified party, as a condition of
such indemnity, shall cooperate in good faith with the indemnifying party in
the defense of any such action or claim.
 
  (d) If the indemnification provided for in this Section 6 is for any reason,
other than pursuant to the terms thereof, judicially determined (by the entry
of a final judgment or decree by a court of competent jurisdiction and the
expiration of time to appeal or the denial of the last right to appeal) to be
unavailable to an indemnified party under subsections (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, in lieu of
indemnifying such indemnified party, 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 and the
Operating Partnership and you from the offering of the Shares. If, however,
the allocation provided by the immediately preceding sentence is not permitted
by applicable law, 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, as applicable, of the Company and the Operating Partnership and you in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities (or actions in respect thereof), as well as
other relevant equitable considerations. The relative benefits received by, as
applicable, the Company and the Operating Partnership taken together and you
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 you equal to the
difference between the last reported sales price per share on the New York
Stock Exchange on the date of this Agreement and the purchase price per share
paid by you pursuant to Section 2 hereof, and as set forth on the cover of the
Prospectus, multiplied by the number of shares of Common Stock purchased by
you pursuant to Section 1 hereof. The relative fault shall be determined by
reference to, among other things, whether the untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company or the Operating Partnership or you and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Company, the Operating
Partnership and you agree that it would not be just and equitable if
contributions pursuant to this subsection (d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this subsection (d). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to
above in this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), you shall not be required to contribute any
amount in excess of the underwriting discounts and commissions applicable to
the Shares purchased by you. 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.
 
  7. Representations and Agreements to Survive Delivery. All representations,
warranties, and agreements of the Company and the Operating Partnership
contained herein or in certificates delivered pursuant hereto, and your
agreements contained in Section 6 hereof, shall remain operative and in full
force and effect regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of you or any controlling
person, the Company and the Operating Partnership or any of their officers,
directors or any controlling persons, and shall survive delivery of the Shares
to you hereunder.

Statement, each Preliminary Prospectus, the Prospectus, and any amendments or
supplements thereto (c) the furnishing of copies of such documents to you, (d)
the registration or qualification of the Shares for offering and sale under
the securities laws of the various states, including the reasonable fees and
disbursements of your counsel relating to such registration or qualification,
(e) the fees payable to the NASD (if any) and the Commission in connection
with their review of the proposed offering of the Shares, (f) all printing and
engraving costs related to preparation of the certificates for the Shares,
including transfer agent and registrar fees, (g) all initial transfer taxes,
if any, (h) all fees and expenses relating to the authorization of the Shares
for trading on the New York Stock Exchange, (i) all travel expenses, including
air fare and accommodation expenses, of representatives of the Company in
connection with the offering of the Shares and (j) all of the other costs and
expenses incident to the performance by the Company of the registration and
offering of the Shares; provided, however, that you will bear and pay the fees
and expenses of your counsel (other than fees and disbursements relating to
the registration or qualification of the Shares for offering and sale under
the securities laws of the various states), your out-of-pocket expenses, and
any advertising costs and expenses incurred by you incident to the public
offering of the Shares.

expenses, including the reasonable fees and disbursements of your counsel.

deemed to be a Contingent Obligation in an amount equal to any such claim.

guaranty is recourse, directly or indirectly to the Borrower), the amount of the
guaranty shall be deemed to be 100% thereof unless and only to the extent that
such other Person has delivered Cash or Cash Equivalents to secure all or any
part of such Person's guaranteed obligations, (ii) in the case of joint and
several guarantees given by a Person in whom the Borrower owns an interest
(which guarantees are non-recourse to the Borrower), to the extent the

amount in excess of 15% shall be deemed to be a Contingent Obligation of the
Borrower, and (iii) in the case of a guaranty (whether or not joint and several)
of an obligation otherwise constituting Debt of such Person, the amount of such
guaranty shall be deemed to be only that amount in excess of the amount of the
obligation constituting Debt of such Person. Notwithstanding anything contained

guarantees of Unused Commitments or of construction loans to the extent the same
have not been drawn.

amounts drawn thereunder, (C) all Contingent Obligations of such Person, (D) all

                                                  ---------
     not specify all of the information required by subsection (d)(ii) above;

     (2)  contains qualifying, conditional or similar language;

(e)    Notice to Borrower.  The Lead Agent shall promptly notify the
       -------------------
Borrower (x) with respect to each Money Market Quote submitted in accordance

the Bank submitting such Money Market Quote and (y) of any Money Market Quote
that amends, modifies or is otherwise inconsistent with a previous Money Market
Quote submitted by such Bank with respect to the same Money Market Quote
Request. Any such subsequent Money Market Quote shall be disregarded by the Lead
Agent unless such subsequent Money Market Quote is submitted solely to correct a
manifest error in such former Money Market Quote. The Lead Agent's notice to the
Borrower shall specify (A) the aggregate principal amount of Money Market Loans
for which offers have been received for each Interest Period specified in the
related Money Market Quote Request, (B) the respective principal amounts and

     (f)   Acceptance and Notice by Borrower. Not later than 1:00 p.m. (New York
           ---------------------------------
City time) on (x) the third Euro-Dollar Business Day prior to the proposed date
of Borrowing, in the case of a LIBOR Auction, or (y) the proposed date of
Borrowing, in the case of an Absolute Rate Auction (or, in either case, such
other time or date as the Borrower and the Lead Agent shall have mutually agreed
and shall have notified to the Banks not later than the date of the Money Market
Quote Request for the first LIBOR Auction or Absolute Rate Auction for which
such change is to be effective), the Borrower shall notify the Lead Agent of its
acceptance or non-acceptance of the offers so notified to it pursuant to
subsection (e). In the case of acceptance, such notice (a "Notice of Money
                                                           ---------------
Market Borrowing") shall specify the aggregate principal amount of offers for
- ----------------
each Interest Period that are accepted. The Borrower may accept any Money Market
Quote in whole or in part; provided that:
                           --------

     (i)   the aggregate principal amount of each Money Market Borrowing
     may not exceed the applicable amount set forth in the related Money Market
     Quote Request;

     (ii)  the principal amount of each Money Market Borrowing must be
     $10,000,000 or a larger multiple of $500,000;

     (iii) acceptance of offers may only be made on the basis of ascending
     Money Market Margins or Money Market Absolute Rates, as the case may be;
     and

     (iv)  the Borrower may not accept any offer that is described in
     subsection (d)(iii) or that otherwise fails to comply with the requirements
     of this Agreement.

(g)   Allocation by Lead Agent. If offers are made by two or more Banks
      ------------------------
with the same Money Market Margins or Money Market Absolute Rates, as the case
may be, for a greater aggregate principal amount than the amount in respect of
which such offers are accepted for the related Interest Period, the principal
amount of Money Market Loans in respect of which such offers are accepted shall
be allocated by the Lead Agent among such Banks as nearly as possible (in
multiples of $500,000, as

                                      37
<PAGE>
 
the Lead Agent may deem appropriate) in proportion to the aggregate principal
amounts of such offers. Determinations by the Lead Agent of the amounts of Money
Market Loans shall be conclusive in the absence of manifest error.

(h)   Notification by Lead Agent. Upon receipt of the Borrower's Notice of
      --------------------------
Money Market Borrowing in accordance with Section 2.3(f) hereof, the Lead Agent
shall, on the date such Notice of Money Market Borrowing is received by the Lead
Agent, notify each Bank of the principal amount of the Money Market Borrowing
accepted by the Borrower and of such Bank's share (if any) of such Money Market
Borrowing and such Notice of Money Market Borrowing shall not thereafter be
revocable by the Borrower. A Bank who is notified that it has been selected to
make a Money Market Loan may designate its Designated Lender (if any) to fund
such Money Market Loan on its behalf, as described in Section 9.6(d). Any
Designated Lender which funds a Money Market Loan shall on and after the time of
such funding become the obligee under such Money Market Loan and be entitled to
receive payment thereof when due. No Bank shall be relieved of its obligation to
fund a Money Market Loan, and no Designated Lender shall assume such obligation,
prior to the time the applicable Money Market Loan is funded.

          Section 2.4  Notice to Banks; Funding of Loans.
                       ---------------------------------      

(a)   Upon receipt of a Notice of Committed Borrowing, the Lead Agent shall
notify each Bank on the same day as it receives the Notice of Committed
Borrowing of the contents thereof and of such Bank's share of such Borrowing and
such Notice of Committed Borrowing shall not thereafter be revocable by the
Borrower.

(b)   Not later than 2:00 P.M. (New York City time) on the date of each
Committed Borrowing, each Bank shall make available its share of such Committed
Borrowing, in Federal or other funds immediately available in New York City, to
the Lead Agent at its address referred to in Section 9.1. The Lead Agent will
make the funds so received from the Banks available to the Borrower at the Lead
Agent's aforesaid address. If the Borrower has requested the issuance of a
Letter of Credit, no later than 12:00 Noon (New York City time) on the date of
such

                                      38
<PAGE>
 
issuance as indicated in the notice delivered pursuant to Section 2.2(b), the
Fronting Bank shall issue such Letter of Credit in the amount so requested and
deliver the same to the Borrower with a copy thereof to the Lead Agent. At the
request of any Bank, the Lead Agent promptly shall deliver copies thereof to
such Bank. Immediately upon the issuance of each Letter of Credit by the
Fronting Bank, such Fronting Bank shall be deemed to have sold and transferred
to each other Bank, and each such other Bank shall be deemed, and hereby agrees,
to have irrevocably and unconditionally purchased and received from the Fronting
Bank, without recourse or warranty, an undivided interest and a participation in
such Letter of Credit, any drawing thereunder, and the obligations of the
Borrower hereunder with respect thereto, and any security therefor or guaranty
pertaining thereto, in an amount equal to such Bank's ratable share thereof
(based upon the ratio its Commitment bears to the aggregate of all Commitments).
Upon any change in any of the Commitments in accordance herewith, there shall be
an automatic adjustment to such participations to reflect such changed shares.
The Fronting Bank shall have the primary obligation to fund any and all draws
made with respect to such Letter of Credit notwithstanding any failure of a
participating Bank to fund its ratable share of any such draw. The Lead Agent
will instruct the Fronting Bank to make such Letter of Credit available to the
Borrower and the Fronting Bank shall make such Letter of Credit available to the
Borrower at the Borrower's aforesaid address or at such address in the United
States as Borrower shall request on the date of the Borrowing.

(c)    Unless the Lead Agent shall have received notice from a Bank prior to
the date of any Borrowing that such Bank will not make available to the Lead
Agent such Bank's share of such Borrowing, the Lead Agent may assume that such
Bank has made such share available to the Lead Agent on the date of such
Borrowing in accordance with subsection (b) of this Section 2.4 and the Lead
Agent may, in reliance upon such assumption, make available to the Borrower on
such date a corresponding amount. If and to the extent that such Bank shall not
have so made such share available to the Lead Agent, such Bank and the Borrower
severally agree to repay to the Lead Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
such amount is made available to the Borrower until

                                      39
<PAGE>

the date such amount is repaid to the Lead Agent, at (i) in the case of the
Borrower, a rate per annum equal to the higher of the Federal Funds Rate and the
interest rate applicable thereto pursuant to Section 2.7 and (ii) in the case of
such Bank, the Federal Funds Rate. If such Bank shall repay to the Lead Agent
such corresponding amount, such amount so repaid shall constitute such Bank's
Loan included in such Borrowing for purposes of this Agreement.

          Section 2.5  Notes.
                       -----      

(a)       The Loans shall be evidenced by the Notes, each of which shall be
payable to the order of each Bank for the account of its Applicable Lending
Office in an amount equal to each such Bank's Commitment.

(b)       Each Bank may, by notice to the Borrower and the Lead Agent, request
that its Loans of a particular type be evidenced by a separate Note in an amount
equal to the aggregate unpaid principal amount of such Loans. Each such Note
shall be in substantially the form of Exhibit A hereto, with appropriate
                                      ---------
modifications to reflect the fact that it evidences solely Loans of the relevant
type. Each reference in this Agreement to the "Note" of such Bank shall be
                                               ----
deemed to refer to and include any or all of such Notes, as the context may
require.
     
(c)       Upon receipt of each Bank's Note, the Lead Agent shall forward such
Note to such Bank. Each Bank shall record the date, amount, type and maturity of
each Loan made by it and the date and amount of each payment of principal made
by the Borrower with respect thereto, and may, if such Bank so elects in
connection with any transfer or enforcement of its Note, endorse on the schedule
forming a part thereof appropriate notations to evidence the foregoing
information with respect to each such Loan then outstanding; provided that the
                                                             --------
failure of any Bank to make any such recordation or endorsement shall not affect
the obligations of the Borrower hereunder or under the Notes. Each Bank is
hereby irrevocably authorized by the Borrower so to endorse its Note and to
attach to and make a part of its Note a continuation of any such schedule as and
when required.

amount thereof, for each day from the date such Loan is made until it becomes
due, at a rate per annum equal to the sum of twenty-five (25) basis points plus
the Base Rate for such day. Such interest shall be payable for each Interest
Period on the last day thereof.

(b)       Each Euro-Dollar Loan shall bear interest on the outstanding principal
amount thereof, for each day during the Interest Period applicable thereto, at a
rate per annum equal to the sum of the Applicable Margin plus the Adjusted
London Interbank Offered Rate for such day.

          Such interest shall be payable for each Interest Period on the last
day thereof and, if such Interest Period is longer than three months, at
intervals of three months after the first day thereof.

          "Adjusted London Interbank Offered Rate" applicable to any Interest
           --------------------------------------
Period means a rate per annum equal to the quotient obtained (rounded upward, if
necessary, to the next higher 1/100 of 1%) by dividing (i) the applicable London
Interbank Offered Rate by (ii) 1.00 minus the Euro-Dollar Reserve Percentage.

          "Euro-Dollar Reserve Percentage" means for any day that percentage
           ------------------------------
(expressed as a decimal) which is in effect on such day, as prescribed by the
Board of Governors of the Federal Reserve System (or any successor) for
determining the maximum reserve requirement for a member bank of the Federal

the Reference Bank in the London interbank market at approximately 11:00 a.m.
(London time) two Euro-Dollar Business Days before the first day of such
Interest Period in an amount approximately equal to the principal amount of the
Euro-Dollar Loan of such Reference Bank to which such Interest Period is to
apply and for a period of time comparable to such Interest Period.

(c)       Subject to Section 8.1, each Money Market LIBOR Loan shall bear
interest on the outstanding principal amount thereof, for the Interest Period
applicable thereto, at a rate per annum equal to the sum of the London Interbank
Offered Rate for such Interest Period (determined in accordance with Section
2.7(b) as if the related Money Market LIBOR Borrowing were a Committed Euro-
Dollar Borrowing) plus (or minus) the Money Market Margin quoted by the Bank
making such Loan in accordance with Section 2.3. Each Money Market Absolute Rate
Loan shall bear interest on the outstanding principal amount thereof, for the
Interest Period applicable thereto, at a rate per annum equal to the Money
Market Absolute Rate quoted by the Bank making such Loan in accordance with
Section 2.3. Such interest shall be payable for each Interest Period on the last
day thereof and, if such Interest Period is longer than ninety days, at
intervals of ninety days after the first day thereof.

(d)       In the event that, and for so long as, any Event of Default shall have
occurred and be continuing, the outstanding principal amount of the Loans, and,
to the extent permitted by law, overdue interest in respect of all Loans, shall
bear interest at the annual rate of the sum of the Prime Rate and four percent
(4%).

(e)       The Lead Agent shall determine each interest rate applicable to the
Loans hereunder. The Lead Agent shall give prompt notice to the Borrower and the

January 1, April 1, July 1, and October 1 during the Term and any extensions
thereof.  Any change in the Borrower's Credit Rating causing it to move into a
different range on the table shall effect an immediate change in the applicable
percentage per annum.  In the event that the Borrower's (or the General
Partner's)  Credit Rating is such that the Rating Agencies' ratings are split
between a higher and a lower rating, the applicable percentage per annum shall
be based upon the lower of such two (2) Credit Ratings.   In the event that
Borrower (or, as applicable, the General Partner) receives more than two (2)
credit ratings and such credit ratings are not equivalent, the applicable fee
shall be determined by the lower of the two (2) highest ratings, provided that
each of said two (2) highest ratings shall be Investment Grade Ratings and at
least one of which shall be an Investment Grade Rating from S&P or Moody's.

(a)       In the event that an Unencumbered Asset Pool Property (or any Separate
Parcel that originally formed a part of an Unencumbered Asset Pool Property) is
sold, transferred or released from the restrictions of Section 5.16 hereof, the
Borrower shall, simultaneously with such sale, transfer or release, prepay the

such a sale, transfer or release. Notwithstanding the foregoing, a simultaneous
like-kind exchange under Section 1031 of the Internal Revenue Code will not be
subject to the provisions of this Section 2.10(a), provided that the exchanged
property has qualified as a New Acquisition and any cash "boot" associated
therewith shall be applied to prepayment of the Loans. Sale of an Unencumbered
Asset Pool Property (or any Separate Parcel that originally formed a part of a
Unencumbered Asset Pool Property) in violation of this Section 2.10 shall
constitute an Event of Default.

(b)       Simultaneously with the closing of any sale of common shares of
beneficial interest, preferred shares of beneficial interest, partnership
interests, limited liability company interests, or other ownership or equity
interests in the Borrower or the General Partner, the Borrower shall,
simultaneously with such sale, prepay the Loans in an amount equal to 100% of
the Net Offering Proceeds.
       
(c)       in the event that the Unsecured Debt Ratio is not maintained as of the
last day of a calendar quarter, either (i) the Borrower will add a Real Property
Asset to the Unencumbered Asset Pool Properties in accordance with this
Agreement which, on a pro forma basis (i.e. the Unsecured Debt Ratio shall be
                      ---------        ---
recalculated to include such Real Property Asset as though the same had been an
Unencumbered Asset Pool Property for the entire applicable period) would result
in compliance with the
   
                                      46

Unsecured Debt Ratio, or (ii) the Borrower shall prepay to the Lead Agent, for
the account of the Banks, an amount necessary to cause the Unsecured Debt Ratio
to be in compliance within ninety (90) days of the date on which the Unsecured
Debt Ratio failed to be maintained. Failure by the Borrower to comply with the
Unsecured Debt Ratio within ninety (90) days of the date of such non-compliance
shall be an Event of Default.

          Section 2.11  Optional Prepayments.
                        --------------------      
       
(a)       The Borrower may, upon at least one Domestic Business Day's notice to
the Lead Agent, prepay to the Lead Agent, for the account of the Banks, any Base
Rate Borrowing in whole at any time, or from time to time in part in amounts
aggregating One Million Dollars ($1,000,000), or an integral multiple of One
Million Dollars ($1,000,000) in excess thereof or, if less, the outstanding
principal balance, by paying the principal amount to be prepaid together with
accrued interest thereon to the date of prepayment. Each such optional
prepayment shall be applied to prepay ratably the Loans of the several Banks
included in such Borrowing.

(b)       Except as provided in Section 8.2, the Borrower may not prepay all or
any portion of the principal amount of any Euro-Dollar Loan prior to the
maturity thereof unless the Borrower shall also pay any applicable expenses
pursuant to Section 2.13. Any such prepayment shall be upon at least three (3)
Euro-Dollar Business Days' notice to the Lead Agent. Any notice of prepayment
delivered pursuant to this Section 2.11(b) shall set forth the amount of such

(e)       The Borrower may at any time return any undrawn Letter of Credit to
the Fronting Bank in whole, but not in part, and the Fronting Bank shall give
the Lead Agent and each of the Banks notice of such return.
   
(f)       The Borrower may at any time and from time to time cancel all or any
part of the Commitments in amounts aggregating One Million Dollars ($1,000,000),
or an integral multiple of One Million Dollars ($1,000,000) in excess thereof,
by the delivery to the Lead Agent and the Banks of a notice of cancellation upon
at least three (3) Domestic Business Days' notice to Lead Agent and the Banks,
whereupon, all or such portion of the Commitments shall terminate as to the
Banks, pro rata on the date set forth in such notice of cancellation, and, if
       --- ----
there are any Loans then outstanding in an aggregate amount which exceeds the
aggregate Commitments (after giving effect to any such reduction), the Borrower
shall prepay to the Lead Agent, for the account of the Banks, all or such
portion of Loans outstanding on such date in accordance with the requirements of
Sections 2.11(a) and (b). In no event shall the Borrower be permitted to cancel
Commitments for which a Letter of Credit has been issued and is outstanding
unless the Borrower returns (or causes to be returned) such Letter of Credit to
the Fronting Bank. The Borrower shall be permitted to designate in its notice of
cancellation which Loans, if any, are to be prepaid.

subject to the other terms of this Agreement. In the event that the Borrower
elects to cancel all or any portion of the Commitments pursuant to Section

          Section 2.12 General Provisions as to Payments.
                       ---------------------------------      
    
(a)       The Borrower shall make each payment of principal of, and interest on,
the Loans and of fees hereunder, not later than 12:00 Noon (New York City time)
on the date when due, in Federal or other funds immediately available in New
York City, to the Lead Agent at its address referred to in Section 9.1. The Lead
Agent will distribute to each Bank its ratable share of each such payment
received by the Lead Agent for the account of the Banks on the same day as
received by the Lead Agent if received by the Lead Agent by 1:00 p.m. (New York
City time), or, if received by the Lead Agent after 1:00 p.m. (New York City
time), on the immediately following Domestic Business Day. If the Lead Agent
shall fail to distribute to a Bank its ratable share of a payment on the same
day it is received or the immediately following Domestic Business Day, as
applicable in accordance with the immediately preceding sentence, the Lead Agent
shall pay to such Bank the interest accrued on such payment at the Federal Funds
Rate, commencing on the day the Lead Agent should have made the payment to such
Bank and ending on the day prior to the date payment is actually made. Whenever
any payment of principal of, or interest on, the Base Rate Loans or of fees
shall be due on a day which is not a Domestic Business Day, the date for payment
thereof shall be extended to the next succeeding Domestic Business Day. Whenever
any payment of principal of, or interest on, the Euro-Dollar Loans shall be due
on a day which is not a Euro-Dollar Business Day, the date for payment thereof
shall be extended to the next succeeding Euro-Dollar Business Day unless such
Euro-Dollar Business Day falls in another calendar month, in which case the date
for payment thereof shall be the next preceding Euro-Dollar Business Day. If the
date for any payment of principal is extended by operation of law or otherwise,
interest thereon shall be payable for such extended time.

(b)       Unless the Lead Agent shall have received notice from the Borrower
prior to the date on which any payment is due to the Banks hereunder that the
Borrower will not make such payment in full, the Lead Agent may assume that the
Borrower has made such payment in full to the Lead Agent on such date and the
Lead Agent may, in reliance upon such assumption, cause to be distribed to

                                      49
<PAGE>

each Bank on such due date an amount equal to the amount then due such Bank. If
and to the extent that the Borrower shall not have so made such payment, each
Bank shall repay to the Lead Agent forthwith on demand such amount distributed
to such Bank together with interest thereon, for each day from the date such
amount is distributed to such Bank until the date such Bank repays such amount
to the Lead Agent, at the Federal Funds Rate.

          Section 2.13   Funding Losses.  If the Borrower makes any payment of
                         --------------                          
principal with respect to any Euro-Dollar Loan (pursuant to Article II, VI or
VIII or otherwise, and specifically including any payments made pursuant to
Sections 2.10 or 2.11) on any day other than the last day of the Interest Period
applicable thereto, or if the Borrower fails to borrow any Euro-Dollar Loans,
after notice has been given to any Bank in accordance with Section 2.4(a), the
Borrower shall reimburse each Bank within 15 days after demand for any resulting
loss or expense incurred by it (or by an existing Participant in the related
Loan; provided that no Participant shall be entitled to receive more than the
Bank with respect to which such Participant is a Participant would be entitled
to receive under this Section 2.13), including (without limitation) any loss
incurred in obtaining, liquidating or employing deposits from third parties, but
excluding loss of margin for the period after any such payment or failure to
borrow, provided that such Bank shall have delivered to the Borrower a
        --------                                                      
certificate as to the amount of such loss or expense and the calculation
thereof, which certificate shall be conclusive in the absence of manifest error.
     
          Section 2.14   Computation of Interest and Fees. Interest based on the
                         --------------------------------
Prime Rate hereunder shall be computed on the basis of a year of 365 days (or
366 days in a leap year) and paid for the actual number of days elapsed
(including the first day but excluding the last day). All other interest and
fees shall be computed on the basis of a year of 360 days and paid for the
actual number of days elapsed (including the first day but excluding the last
day).

          Section 2.15   Method of Electing Interest Rates.
                         ---------------------------------      
     
(a)       The Loans included in each Borrowing shall bear interest initially at
the type of rate specified by the Borrower in the applicable Notice of Committed
Borrowing. Thereafter, the Borrower may from time to time elect to change or
continue the type of interest rate borne by each Group of Loans (subject in each
case to the provisions of Article VIII), as follows:

     (i)  if such Loans are Base Rate Loans, the Borrower may elect to convert
     such Loans to Euro-Dollar Loans as of any Euro-Dollar Business Day;

     (ii) if such Loans are Euro-Dollar Loans, the Borrower may elect to convert
     such Loans to Base Rate Loans or elect to continue such Loans as Euro-
     Dollar Loans for an additional Interest Period, in each case effective on
     the last day of the then current Interest Period applicable to such Loans.

Each such election shall be made by delivering a notice (a "Notice of Interest
                                                            ------------------
Rate Election") to the Lead Agent at least three (3) Euro-Dollar Business Days
- -------------                                                                 
before the conversion or continuation selected in such notice is to be effective
(unless the relevant Loans are to be continued as Base Rate Loans, in which case
such notice shall be delivered to the Lead Agent no later than 12:00 Noon (New
York City time) at least one (1) Domestic Business Day before such continuation
is to be effective).  A Notice of Interest Rate Election may, if it so
specifies, apply to only a portion of the aggregate principal amount of the
relevant Group of Loans; provided that (i) such portion is allocated ratably
                         --------                                           
among the Loans comprising such Group, (ii) the portion to which such notice
applies, and the remaining portion to which it does not apply, are each
$1,000,000 or any larger multiple of $1,000,000, (iii) there shall be no more
than ten (10) Borrowings comprised of Euro-Dollar Loans outstanding at any time
under this Agreement, (iv) no Loan may be continued as, or converted into, a
Euro-Dollar Loan when any Event of Default has occurred and is continuing, and
(v) no Interest Period shall extend beyond the Maturity Date.

                                      51
<PAGE>

(b)       Each Notice of Interest Rate Election shall specify:
    
     (i)  the Group of Loans (or portion thereof) to which such notice applies;

     (ii) the date on which the conversion or continuation selected in such
     notice is to be effective, which shall comply with the applicable clause of
     subsection (a) above;

     (iii) if the Loans comprising such Group are to be converted, the new type
     of Loans and, if such new Loans are Euro-Dollar Loans, the duration of the
     initial Interest Period applicable thereto; and

     (iv)  if such Loans are to be continued as Euro-Dollar Loans for an
     additional Interest Period, the duration of such additional Interest
     Period.

Each Interest Period specified in a Notice of Interest Rate Election shall
comply with the provisions of the definition of Interest Period.

(c)       Upon receipt of a Notice of Interest Rate Election from the Borrower
pursuant to subsection (a) above, the Lead Agent shall notify each Bank on the
same day as it receives such Notice of Interest Rate Election of the contents
thereof and such notice shall not thereafter be revocable by the Borrower. If
the Borrower fails to deliver a timely Notice of Interest Rate Election to the
Lead Agent for any Group of Euro-Dollar Loans, such Loans shall be converted
into Base Rate Loans on the last day of the then current Interest Period
applicable thereto.

          Section 2.16 Letters of Credit.    Subject to the terms contained in
                       -----------------                             
this Agreement and the other Loan Documents, upon the receipt of a notice in
accordance with Section 2.2(b) requesting the issuance of a Letter of Credit,
the Fronting Bank shall issue a Letter of Credit or Letters of Credit in such
form as is reasonably acceptable to the Borrower in an amount or amounts equal
to the amount or amounts requested by the Borrower.
 
                                      52
<PAGE>

(b)       Each Letter of Credit shall be issued in the minimum amount of One
Million Dollars ($1,000,000).

(c)       The Letter of Credit Usage shall be no more than Twenty-Five Million
Dollars ($25,000,000) at any one time.

(d)       There shall be no more than three (3) Letters of Credit outstanding at
any one time.

(e)       In the event of any request for a drawing under any Letter of Credit
by the beneficiary thereunder, the Fronting Bank shall endeavor to notify the
Borrower and the Lead Agent (and the Lead Agent shall endeavor to notify each
Bank thereof) on or before the date on which the Fronting Bank intends to honor
such drawing, and, except as provided in this subsection (e), the Borrower shall
reimburse the Fronting Bank, in immediately available funds, on the same day on
which such drawing is honored in an amount equal to the amount of such drawing.
Notwithstanding anything contained herein to the contrary, however, unless the
Borrower shall have notified the Lead Agent, and the Fronting Bank prior to
11:00 a.m. (New York time) on the Domestic Business Day immediately prior to the
date of such drawing that the Borrower intends to reimburse the Fronting Bank
for the amount of such drawing with funds other than the proceeds of the Loans,
the Borrower shall be deemed to have timely given a Notice of Committed
Borrowing pursuant to Section 2.2 to the Lead Agent, requesting a Borrowing of
Base Rate Loans on the date on which such drawing is honored and in an amount
equal to the amount of such drawing. Each Bank (other than the Fronting Bank)
shall, in accordance with Section 2.4(b), make available its share of such
Borrowing to the Lead Agent, the proceeds of which shall be applied directly by
the Lead Agent to reimburse the Fronting Bank for the amount of such draw. In
the event that any such Bank fails to make available to the Fronting Bank the
amount of such Bank's participation on the date of a drawing, the Fronting Bank
shall be entitled to recover such amount on demand from such Bank together with
interest at the Federal Funds Rate commencing on the date such drawing is
honored.

(f)       If, after the date hereof, any change in any law or regulation or in
the interpretation thereof by any court or administrative or governmental
authority
 
                                      53

charged with the administration thereof shall either (i) impose, modify or deem
applicable any reserve, special deposit or similar requirement against letters
of credit issued by, or assets held by, or deposits in or for the account of, or
participations in any letter of credit, upon any Bank (including the Fronting
Bank) or (ii) impose on any Bank any other condition regarding this Agreement or
such Bank (including the Fronting Bank) as it pertains to the Letters of Credit
or any participation therein and the result of any event referred to in the
preceding clause (i) or (ii) shall be to increase, by an amount deemed by the
Fronting Bank or such Bank to be material, the cost to the Fronting Bank or any
Bank of issuing or maintaining any Letter of Credit or participating therein
then the Borrower shall pay to the Fronting Bank or such Bank, within 15 days
after written demand by such Bank (with a copy to the Lead Agent), which demand
shall be accompanied by a certificate showing, in reasonable detail, the
calculation of such amount or amounts, such additional amounts as shall be
required to compensate the Fronting Bank or such Bank for such increased costs
or reduction in amounts received or receivable hereunder.

(g)       The Borrower hereby agrees to protect, indemnify, pay and save the
Fronting Bank harmless from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
attorneys' fees and disbursements) which the Fronting Bank may incur or be
subject to as a result of (i) the issuance of the Letters of Credit, other than
as a result of the gross negligence or wilful misconduct of the Fronting Bank or
(ii) the failure of the Fronting Bank to honor a drawing under any Letter of
Credit as a result of any act or omission, whether rightful or wrongful, of any
present or future de jure or de facto government or Governmental Authority
                  -- ----    -- -----
(collectively, "Governmental Acts"), other than as a result of the gross
                -----------------
negligence or wilful misconduct of the Fronting Bank. As between the Borrower
and the Fronting Bank, the Borrower assumes all risks of the acts and omissions
of, or misuses of, the Letters of Credit issued by the Fronting Bank, by the
beneficiaries of such Letters of Credit. In furtherance and not in limitation of
the foregoing, the Fronting Bank shall not be responsible (i) for the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connec-

                                      54

tion with the application for and issuance of such Letters of Credit, even if it
should in fact prove to be in any or all respects invalid, insufficient,
inaccurate, fraudulent or forged; (ii) for the validity or insufficiency of any
instrument transferring or assigning or purporting to transfer or assign any
such Letter of Credit or the rights or benefits thereunder or proceeds thereof,
in whole or in part, which may prove to be invalid or ineffective for any
reason; (iii) for failure of the beneficiary of any such Letter of Credit to
comply fully with conditions required in order to draw upon such Letter of
Credit; (iv) for errors, omissions, interruptions or delays in transmission or
delivery of any message, by mail, cable, telegraph, telex, facsimile
transmission, or otherwise; (v) for errors in interpretation of any technical
terms; (vi) for any loss or delay in the transmission or otherwise of any
documents required in order to make a drawing under any such Letter of Credit or
of the proceeds thereof; (vii) for the misapplication by the beneficiary of any
such Letter of Credit of the proceeds of such Letter of Credit; and (viii) for
any consequence arising from causes beyond the control of the Fronting Bank,
including any Government Acts, in each case other than as a result of the gross
negligence or willful misconduct of the Fronting Bank. None of the above shall
affect, impair or prevent the vesting of the Fronting Bank's rights and powers
hereunder. In furtherance and extension and not in limitation of the specific
provisions hereinabove set forth, any action taken or omitted by the Fronting
Bank under or in connection with the Letters of Credit issued by it or the
related certificates, if taken or omitted in good faith, shall not put the
Fronting Bank under any resulting liability to the Borrower.
   
(h)       If the Fronting Bank or the Lead Agent is required at any time,
pursuant to any bankruptcy, insolvency, liquidation or reorganization law or
otherwise, to return to the Borrower any reimbursement by the Borrower of any
drawing under any Letter of Credit, each Bank shall pay to the Fronting Bank or
the Lead Agent, as the case may be, its share of such payment, but without
interest thereon unless the Fronting Bank or the Lead Agent is required to pay
interest on such amounts to the person recovering such payment, in which case
with interest thereon, computed at the same rate, and on the same 

                                      55

basis, as the interest that the Fronting Bank or the Lead Agent is required to
pay.

                        -------------------

                       -------------------
power and authority to execute, deliver and carry out the terms and provisions

contravene any applicable provision of any law, statute, rule, regulation,
order, writ, injunction or decree of any court or governmental instrumentality
applicable to Borrower or (ii) will conflict with or result in any breach of,
any of the terms, covenants, conditions or provisions of, or constitute a
default under, or result in the creation or imposition of (or the obligation to
create or impose) any Lien upon any of the property or assets of the Borrower
pursuant to the terms of any material indenture, mortgage, deed of trust, or
other agreement or other instrument to which the Borrower (or of any partnership

or the other Loan Documents.

amount of One Million Dollars ($1,000,000) or more entered by a court or courts

person" (as such term is defined in Section 4975(e)(2) of the Code) with respect
to any funded employee benefit plan and none of the assets of any such plans
have been invested in a manner that would cause the transactions contemplated by
the Loan Documents to constitute a nonexempt prohibited transaction (as such
term is defined in Section 4975 of the Code or Section 406 of ERISA).

          Section  4.7.  Environmental Compliance.  To the best of Borrower's

the terms and conditions of all such Environmental Approvals, and is also in
compliance in all material respects with all other Environmental Laws or any
plan, order, decree, judgment, injunction, notice or demand letter issued,

disclosed to the Lead Agent as of the Closing Date, to Borrower's actual
knowledge:

     (i)  There are no Environmental Claims or investigations pending or
     threatened by any Governmental Authority with respect to any alleged
     failure by the Borrower to have any Environmental Approval required in
     connection with the conduct of the business of the Borrower on any of the
     Unencumbered Asset Pool Properties, or with respect to any generation,

(l)       (i) any Environmental Claim shall have been asserted against the
Borrower or any Environmental Affiliate, (ii) any release, emission, discharge

         Section 6.2. Rights and Remedies.  (a) Upon the occurrence of any 
                      -------------------
Event of Default described in Sections 6.1(f) or (g), the unpaid principal
amount of, and any and all accrued interest on, the Loans and any and all
accrued fees and other Obligations hereunder shall automatically become
immediately due and payable, with all additional interest from time to time
accrued thereon and without presentation, demand, or protest or other
requirements of any kind (including, without limi-


                                      85
<PAGE>
 
tation, valuation and appraisement, diligence, presentment, notice of intent to
demand or accelerate and notice of acceleration), all of which are hereby
expressly waived by the Borrower; and upon the occurrence and during the
continuance of any other Event of Default, the Lead Agent may exercise any of
its rights and remedies hereunder and by written notice to the Borrower, declare
the unpaid principal amount of and any and all accrued and unpaid interest on
the Loans and any and all accrued fees and other Obligations hereunder to be,
and the same shall thereupon be, immediately due and payable with all additional
interest from time to time accrued thereon and without presentation, demand, or
protest or other requirements of any kind other than as provided in the Loan
Documents (including, without limitation, valuation and appraisement, diligence,
presentment, and notice of intent to demand or accelerate), all of which are
hereby expressly waived by the Borrower.

(b)      Notwithstanding the foregoing, upon the occurrence and during the
continuance of any Event of Default other than any Event of Default described in
Sections 6.1(f) or (g), the Lead Agent shall not exercise any of its rights and
remedies hereunder nor declare the unpaid principal amount of and any and all
accrued and unpaid interest on the Loans and any and all accrued fees and other
Obligations hereunder to be immediately due and payable, until such time as the
Lead Agent shall have delivered a notice to the Banks specifying the Event of
Default which has occurred and whether Lead Agent recommends the acceleration of
the Obligations due hereunder or the exercise of other remedies hereunder. The
Banks shall notify the Lead Agent if they approve or disapprove of the
acceleration of the Obligations due hereunder or the exercise of such other
remedy recommended by Lead Agent within five (5) Domestic Business Days after
receipt of such notice. If any Bank shall not respond within such five (5)
Domestic Business Day period, then such Bank shall be deemed to have accepted
Lead Agent's recommendation for acceleration of the Obligations due hereunder or
the exercise of such other remedy. If the Required Banks shall approve the
acceleration of the Obligations due hereunder or the exercise of such other
remedy, then Lead Agent shall declare the unpaid principal amount of and any and
all accrued and unpaid interest on the Loans and any and all accrued fees and
other Obligations hereunder to be immediately due and payable

                                      86
<PAGE>

or exercise such other remedy approved by the Required Banks. If the Required
Banks shall neither approve nor disapprove the acceleration of the Obligations
due hereunder or such other remedy recommended by Lead Agent, then Lead Agent
may accelerate the Obligations due hereunder or exercise any of its rights and
remedies hereunder in its sole discretion. If the Required Banks shall
disapprove the acceleration of the Obligations due hereunder or the exercise of
such other remedy recommended by Lead Agent, but approve of another remedy, then
to the extent permitted hereunder, Lead Agent shall exercise such remedy. In the
event the Lead Agent exercises any remedy provided in any of the Loan Documents,
the Lead Agent shall act as a collateral agent for the Banks.

       Section 6.3.  Notice of Default.  If the Lead Agent shall not already 
                     -----------------
have given any notice to the Borrower under Section 6.1, the Lead Agent shall
give notice to the Borrower under Section 6.1 promptly upon being requested to
do so by the Required Banks and shall thereupon notify all the Banks thereof.

      Section 6.4. Actions in Respect of Letters of Credit. (a) If, at any 
                   ---------------------------------------
time and from time to time, any Letter of Credit shall have been issued
hereunder and an Event of Default shall have occurred and be continuing, then,
upon the occurrence and during the continuation thereof, the Lead Agent may,
whether in addition to the taking by the Lead Agent of any of the actions
described in this Article or otherwise, make a demand upon the Borrower to, and
forthwith upon such demand (but in any event within ten (10) days after such
demand) the Borrower shall, pay to the Lead Agent, on behalf of the Banks, in
same day funds at the Lead Agent's office designated in such demand, for deposit
in a special cash collateral account (the "Letter of Credit Collateral Account")
                                           -----------------------------------
to be maintained in the name of the Lead Agent (on behalf of the Banks) and
under its sole dominion and control at such place as shall be designated by the
Lead Agent, an amount equal to the amount of the Letter of Credit Usage under
the Letters of Credit. Interest shall accrue on the Letter of Credit Collateral
Account at a rate equal to the rate on overnight funds.

(b)       The Borrower hereby pledges, assigns and grants to the Lead Agent, as
administrative agent for its benefit and the ratable benefit of the Banks a lien
on  


                                      87

and a security interest in, the following collateral (the "Letter of Credit

     and all certificates and instruments, if any, from time to time
     representing or evidencing the Letter of Credit Collateral Account;

     (ii)  all notes, certificates of deposit and other instruments from time to
     time hereafter delivered to or otherwise possessed by the Lead Agent for or
     on behalf of the Borrower in substitution for or in respect of any or all
     of the then existing Letter of Credit Collateral;

     (iii) all interest, dividends, cash, instruments and other property from
     time to time received, receivable or otherwise distributed in respect of or
     in exchange for any or all of the then existing Letter of Credit
     Collateral; and or all of the foregoing Letter of Credit Collateral.

     (iv) to the extent not covered by the above clauses, all proceeds of any of
     Credit Collateral or (ii) create or permit to exist any lien, security
     interest or other charge or encumbrance upon or with respect to any of the
     Letter of Credit Collateral, except for the security interest created by
     this Section 6.4.

The lien and security interest granted hereby secures the payment of all
obligations of the Borrower now or hereafter existing hereunder and under any
other Loan Document.

(c)       The Borrower hereby authorizes the Lead Agent for the ratable benefit
of the Banks to apply, from time to time after funds are deposited in the Letter
of Credit Collateral Account, funds then held in the Letter of Credit Collateral
Account to the payment of any amounts, in such order as the Lead Agent may
elect, as shall have become due and payable by the Borrower to the Banks in
respect of the Letters of Credit.

(d)       Neither the Borrower nor any Person claiming or acting on behalf of or
through the Borrower shall have any right to withdraw any of the funds held in
the Letter of Credit Collateral Account, except as provided in Section 6.4(h)
hereof.

(e)       The Borrower agrees that it will not (i) sell or otherwise dispose of
any interest in the Letter 

                                      88
<PAGE>

of Credit Collateral or (ii) create or permit to exist any lien, security 
interest or other charge or encumbrance upon or with respect to any of the 
Letter of Credit Collateral, except for the security interest created by this 
Section 6.4.

(f)       If any Event of Default shall have occurred and be continuing:

     (i)  The Lead Agent may, in its sole discretion, without notice to the
     Borrower except as required by law and at any time from time to time,
     charge, set off or otherwise apply all or any part of first, (x) amounts
                                                           -----
     previously drawn on any Letter of Credit that have not been reimbursed by
     the Borrower and (y) any Letter of Credit Usage described in clause (ii) of
     the definition thereof that are then due and payable and second, any other
                                                              ------
     unpaid Obligations then due and payable against the Letter of Credit
     Collateral Account or any part thereof, in such order as the Lead Agent
     shall elect. The rights of the Lead Agent under this Section 6.4 are in
     addition to any rights and remedies which any Bank may have.

     (ii)  The Lead Agent may also exercise, in its sole discretion, in respect
     of the Letter of Credit Collateral Account, in addition to the other rights
     and remedies provided herein or otherwise available to it, all the rights
     and remedies of a secured party upon default under the Uniform Commercial
     Code in effect in the State of New York at that time.

(g)       The Lead Agent shall be deemed to have exercised reasonable care in
the custody and preservation of the Letter of Credit Collateral if the Letter of
Credit Collateral is accorded treatment substantially equal to that which the
Lead Agent accords its own property, it being understood that, assuming such
treatment, the Lead Agent shall not have any responsibility or liability with
respect thereto.

(h)       At such time as all Events of Default have been cured or waived in
writing, all amounts remaining in the Letter of Credit Collateral Account shall
be promptly returned to the Borrower. Absent such cure or written

                                      89

waiver, any surplus of the funds held in the Letter of Credit Collateral Account
and remaining after payment in full of all of the Obligations of the Borrower
hereunder and under any other Loan Document after the Maturity Date shall be
paid to the Borrower or to whomsoever may be lawfully entitled to receive such
surplus.

                                THE LEAD AGENT

      Section 7.1.  Appointment and Authorization.  Each Bank irrevocably
                    -----------------------------

refrain from exercising the same as though it were not the Lead Agent, and
Morgan and its affiliates may accept deposits from, lend money to, and generally
engage in any kind of business with the Borrower or any subsidiary or affiliate
of the Borrower as if it were not the Lead Agent hereunder, and the term "Bank"
and "Banks" shall include Morgan in its individual capacity.

      Section 7.5.  Liability of Lead Agent.  Neither the Lead Agent nor any of
                    -----------------------
its affiliates nor any of their respective directors, officers, agents or
employees shall be liable for any action taken or not taken by it in connection
herewith (i) with the consent or at the request of the Required Banks or, where
required by the terms of this Agreement, all of the Banks, or (ii) in the
absence of its own gross negligence or willful misconduct. Neither the Lead
Agent nor any of its directors, officers, agents or employees shall be
responsible for or have any duty to ascertain, inquire into or verify (i) any
statement, warranty or representation made in connection with this Agreement or
any borrowing hereunder; (ii) the performance or observance of any of the
covenants or agreements of the Borrower; (iii) the satisfaction of any condition
specified in Article III, except receipt of items required to be delivered to
the Lead Agent; or (iv) the validity, effectiveness or genuineness of this
Agreement, the other Loan Documents or any other instrument or writing furnished

faith to be genuine or to be signed by the proper party or parties.

this Agreement.

           Section 7.7. Credit Decision.  Each Bank acknowledges that it has,
                        ---------------
independently and without reliance upon the Lead Agent or any other Bank, and

own credit analysis and decision to enter into this Agreement. Each Bank also
acknowledges that it will, independently and without reliance upon the

                                      91
<PAGE>
 
Lead Agent or any other Bank, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking any action under this Agreement.

           Section 7.8. Successor Lead Agent.  The Lead Agent may resign at any
                        --------------------
time by giving notice thereof to the Banks and the Borrower. In addition, if the
Lead Agent at any time shall have been finally determined to have committed
gross negligence or willful misconduct in connection with its performance of its

Lead Agent shall resign. Upon any such resignation, the Required Banks shall
have the right to appoint a successor Lead Agent with the consent of the
Borrower provided that no Event of Default shall have occurred and be
continuing. If no successor Lead Agent shall have been so appointed by the
Required Banks, and shall have accepted such appointment, within 30 days after
the retiring Lead Agent gives notice of resignation, then the retiring Lead
Agent may, on behalf of the Banks, appoint a successor Lead Agent, which shall
be a commercial bank organized or licensed under the laws of the United States
of America or of any State thereof and having a combined capital and surplus of
at least $50,000,000. Upon the acceptance of its appointment as the Lead Agent
hereunder by a successor Lead Agent, such successor Lead Agent shall thereupon
succeed to and become vested with all the rights and duties of the retiring Lead
Agent, and the retiring Lead Agent shall be discharged from its duties and
obligations hereunder first accruing or arising after the effective date of such
retirement. After any retiring Lead Agent's resignation hereunder as Lead Agent,
the provisions of this Article shall inure to its benefit as to any actions
taken or omitted to be taken by it while it was the Lead Agent.

           If, at any time during the Term, the Lead Agent shall no longer have
any Commitment under this Agreement, the Lead Agent shall give notice of its
offer to resign to the Banks and the Borrower.  Upon any such offer of
resignation, the Required Banks shall have the right to appoint a successor Lead
Agent or to retain the Lead Agent with the consent of the Borrower, provided
that no Event of Default shall be outstanding.

                            CHANGE IN CIRCUMSTANCES

          Section 8.1. Basis for Determining Interest Rate Inadequate or Unfair.
                       -------------------------------------------------------- 
If on or prior to the first day of any Interest Period for any Euro-Dollar
Borrowing or Money Market Borrowing:

(a)       the Lead Agent is advised by the Reference Bank that deposits in
dollars (in the applicable amounts) are not being offered to the Reference Bank
in the relevant market for such Interest Period, or

(b)       Banks having 50% or more of the aggregate amount of the affected Loans
advise the Lead Agent that the Adjusted London Interbank Offered Rate as
determined by the Lead Agent will not adequately and fairly reflect the cost to
such Banks of funding their Euro-Dollar Loans for such Interest Period, the Lead
Agent shall forthwith give notice thereof to the Borrower and the Banks,
whereupon until the Lead Agent notifies the Borrower that the circumstances
giving rise to such suspension no longer exist, the obligations of the Banks to
make Euro-Dollar Loans, or to continue or convert outstanding Loans as or into
Euro-Dollar Loans, as the case may be, shall be suspended, and each outstanding
Euro-Dollar Loan shall be converted into a Base Rate Loan on the last day of the
then current Interest Period applicable thereto. Unless the Borrower notifies
the Lead Agent at least two Domestic Business Days before the date of any Euro-
Dollar Borrowing or Money Market LIBOR Borrowing for which a Notice of Borrowing
has previously been given that it

                                      93
<PAGE>

elects not to borrow on such date, (i) if such Borrowing is a Committed
Borrowing, such Borrowing shall instead be made as a Base Rate Borrowing, and
(ii) if such Borrowing is a Money Market LIBOR Borrowing, the Money Market LIBOR
Loans comprising such Borrowing shall bear interest for each day from and
including the first day to but excluding the last day of the Interest Period
applicable thereto at the Base Rate for such day.

          Section 8.2. Illegality.  If, after the date of this Agreement, the
                       ----------
adoption of any applicable law, rule or regulation, or any change in any
existing applicable law, rule or regulation, or any change in the interpretation
or administration thereof by any governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by any Bank (or its Euro-Dollar Lending Office) with any request or
directive (whether or not having the force of law) of any such authority,
central bank or comparable agency shall make it unlawful or impossible for any
Bank (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-
Dollar Loans or Money Market Loans or to participate in any Letter of Credit
issued by the Fronting Bank, or, with respect to the Fronting Bank, to issue any
Letter of Credit, and such Bank shall so notify the Lead Agent, the Lead Agent
shall forthwith give notice thereof to the other Banks and the Borrower,
whereupon until such Bank notifies the Borrower and the Lead Agent that the
circumstances giving rise to such suspension no longer exist, the obligation of
such Bank to make or convert Euro-Dollar Loans or Money Market Loans, or to
participate in any Letter of Credit issued by the Fronting Bank or, with respect
to the Fronting Bank, to issue any Letter of Credit, shall be suspended. Before
giving any notice to the Lead Agent pursuant to this Section, such Bank shall
designate a different Euro-Dollar Lending Office if such designation will avoid
the need for giving such notice and will not, in the judgment of such Bank, be
otherwise disadvantageous to such Bank. If such Bank shall determine that it may
not lawfully continue to maintain and fund any of its outstanding Euro-Dollar
Loans or Money Market Loans (as the case may be) to maturity and shall so
specify in such notice, the Borrower shall immediately prepay in full the then
outstanding principal amount of each such Euro-Dollar Loan or Money Market Loan,
together with accrued interest thereon. Concurrently with prepaying each such


                                      94
<PAGE>
 
Euro-Dollar Loan, the Borrower shall borrow a Base Rate Loan in an equal
principal amount from such Bank (on which interest and principal shall be
payable contemporaneously with the related Euro-Dollar Loans or Money Market
Loans of the other Banks), and such Bank shall make such a Base Rate Loan.

          Section 8.3  Increased Cost and Reduced Return.
                       ---------------------------------      
      
(a)       If, after (x) the date hereof, in the case of any Committed Loan or
any obligation to make Committed Loans or (y) the date of the related Money
Market Quote, in the case of any Money Market Loan, the adoption of any
applicable law, rule or regulation, or any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank (or its
Applicable Lending Office) with any request or directive (whether or not having
the force of law) of any such authority, central bank or comparable agency shall
impose, modify or deem applicable any reserve (including, without limitation,
any such requirement imposed by the Board of Governors of the Federal Reserve
System (but excluding with respect to any Euro-Dollar Loan any such requirement
reflected in an applicable Euro-Dollar Reserve Percentage)), special deposit,
insurance assessment or similar requirement against assets of, deposits with or
for the account of, or credit extended by, any Bank (or its Applicable Lending
Office) or shall impose on any Bank (or its Applicable Lending Office) or on the
London interbank market any other condition affecting its Euro-Dollar Loans or
Money Market LIBOR Loans, its Note, or its obligation to make Euro-Dollar Loans,
and the result of any of the foregoing is to increase the cost to such Bank (or
its Applicable Lending Office) of making or maintaining any Euro-Dollar Loan, or
to reduce the amount of any sum received or receivable by such Bank (or its
Applicable Lending Office) under this Agreement or under its Note with respect
thereto, by an amount deemed by such Bank to be material, then, within 15 days
after demand by such Bank (with a copy to the Lead Agent), which demand shall be
accompanied by a certificate showing, in reasonable detail, the calculation of
such amount or amounts, the Borrower shall pay to such Bank such

                                      95
<PAGE>
 
additional amount or amounts as will compensate such Bank for such increased
cost or reduction.

(b)       If any Bank shall have determined that, after the date hereof, the
adoption of any applicable law, rule or regulation regarding capital adequacy,
or any change in any such law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or any request or directive regarding capital adequacy (whether or not
having the force of law) of any such authority, central bank or comparable
agency, has or would have the effect of reducing the rate of return on capital
of such Bank (or its Parent) as a consequence of such Bank's obligations
hereunder to a level below that which such Bank (or its Parent) could have
achieved but for such adoption, change, request or directive (taking into
consideration its policies with respect to capital adequacy) by an amount deemed
by such Bank to be material, then from time to time, within 15 days after demand
by such Bank (with a copy to the Lead Agent), which demand shall be accompanied
by a certificate showing, in reasonable detail, the calculation of such amount
or amounts, the Borrower shall pay to such Bank such additional amount or
amounts as will compensate such Bank (or its Parent) for such reduction.


(c)       Each Bank will promptly notify the Borrower and the Lead Agent of any
event of which it has knowledge, occurring after the date hereof, which will
entitle such Bank to compensation pursuant to this Section and will designate a
different Applicable Lending Office if such designation will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Bank, be otherwise disadvantageous to such Bank. A certificate of any Bank
claiming compensation under this Section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, such Bank may use any reasonable
averaging and attribution methods.

             -----      

     (a)  Any and all payments by the Borrower to or for the account of any Bank
or the Lead Agent hereunder or under any other Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Bank and the
                                  ---------
Lead Agent, taxes imposed on its income, and franchise taxes imposed on it, by
the jurisdiction under the laws of which such Bank or the Lead Agent (as the
case may be) is organized or any political subdivision thereof and, in the case
of each Bank, taxes imposed on its income, and franchise or similar taxes
imposed on it, by the jurisdiction of such Bank's Applicable Lending Office or
any political subdivision thereof (and, if different from the jurisdiction of
such Bank's Applicable Lending Office, the jurisdiction of the domicile of its
Loans either established by the Bank pursuant to Section 9.12 or determined by
the applicable taxing authorities)(all such non-excluded taxes, duties, levies,
imposts, deductions, charges, withholdings and liabilities being hereinafter
referred to as "Taxes"). If the Borrower shall be required by law to deduct any
                -----
Taxes from or in respect of any sum payable hereunder or under any Note or
Letter of Credit or participation therein to any Bank or the Lead Agent, (i) the
sum payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 8.4) such Bank, the Fronting Bank or the Lead Agent (as the case
may be) receives an amount equal to the sum it would have received had no such
deductions been made, (ii) the Borrower shall make such deductions, (iii) the
Borrower shall pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law and (iv) the Borrower shall
furnish to the Lead Agent, at its address referred to in Section 9.1, the
original or a certified copy of a receipt evidencing payment thereof.

     (b)  In addition, the Borrower agrees to pay any present or future stamp or
documentary taxes and any other excise or property taxes, or charges or similar
levies which arise from any payment made hereunder or under any Note or Letter
of Credit or participation therein or from the execution or delivery of, or
other-

                                      97
<PAGE>
 
wise with respect to, this Agreement or any Note or Letter of Credit or
participation therein (hereinafter referred to as "Other Taxes").
                                                   -----------

     (c)  The Borrower agrees to indemnify each Bank, the Fronting Bank and the
Lead Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on
amounts payable under this Section 8.4) paid by such Bank, the Fronting Bank or
the Lead Agent (as the case may be) and any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto. Any payment
required under this indemnification shall be made within 15 days from the date
such Bank, the Fronting Bank or the Lead Agent (as the case may be) makes demand
therefor.

     (d)  Each Bank organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Bank listed on the signature pages hereof and on
or prior to the date on which it becomes a Bank in the case of each other Bank,
and from time to time thereafter if requested in writing by the Borrower (but
only so long as such Bank remains lawfully able to do so), shall provide the
Borrower with Internal Revenue Service form 1001 or 4224, as appropriate, or any
successor form prescribed by the Internal Revenue Service, certifying that such
Bank is entitled to benefits under an income tax treaty to which the United
States is a party which reduces the rate of withholding tax on payments of
interest or certifying that the income receivable pursuant to this Agreement is
effectively connected with the conduct of a trade or business in the United
States. If the form provided by a Bank at the time such Bank first became a
party to this Agreement or at any time thereafter (other than solely by reason
of a change in United States law or a change in the terms of any treaty to which
the United States is a party after the date hereof) indicates a United States
interest withholding tax rate in excess of zero (or would have indicated such a
withholding tax rate if such form had been submitted and completed accurately
and completely and either was not submitted or was not completed accurately and
completely), or if a Bank otherwise is subject to United States interest
withholding tax at a rate in excess of zero at any time for any reason (other
than solely by

                                      98
<PAGE>
 
reason of a change in United States law or regulation or a change in any treaty
to which the United States is a party after the date hereof), withholding tax at
such rate shall be considered excluded from "Taxes" as defined in Section
8.4(a). In addition, any amount that otherwise would be considered "Taxes" or
"Other Taxes" for purposes of this Section 8.4 shall be excluded therefrom if
the Bank either has transferred the domicile of its Loans pursuant to Section
9.12 or changed the Applicable Lending Office with respect to such Loans and
such amount would not have been incurred had such transfer or change not been
made.

    (e)  For any period with respect to which a Bank has failed to provide the
Borrower with the appropriate form pursuant to Section 8.4(d) (unless such
failure is due to a change in treaty, law or regulation occurring subsequent to
the date on which a form originally was required to be provided), such Bank
shall not be entitled to indemnification under Section 8.4(a) with respect to
Taxes imposed by the United States; provided, however, that should a Bank, which
                                    --------  -------
is otherwise exempt from or subject to a reduced rate of withholding tax, become
subject to Taxes because of its failure to deliver a form required hereunder,
the Borrower shall take such steps as such Bank shall reasonably request to
assist such Bank to recover such Taxes.

    (f)  If the Borrower is required to pay additional amounts to or for the
account of any Bank pursuant to this Section 8.4, then such Bank will change the
jurisdiction of its Applicable Lending Office so as to eliminate or reduce any
such additional payment which may thereafter accrue if such change, in the
judgment of such Bank, is not otherwise disadvantageous to such Bank.

Section 8.5  Base Rate Loans Substituted for Affected Euro-Dollar Loans.
             ----------------------------------------------------------
If (i) the obligation of any Bank to make, or convert outstanding Loans to,
Euro-Dollar Loans has been suspended pursuant to Sections 8.1 or 8.2 or (ii)
any Bank has demanded compensation under Section 8.3 or 8.4 with respect to its
Euro-Dollar Loans and the Borrower shall, by at least five Euro-Dollar Business
Days' prior notice to such Bank through the Lead Agent, have elected that the
provisions of this Section shall apply to such Bank, then, unless and until such
Bank notifies the Borrower that the circumstances giving

                                      99
<PAGE>
 
rise to such suspension or demand for compensation no longer exist:

    (a)  all Loans which would otherwise be made by such Bank as Euro-Dollar
Loans shall be made instead as Base Rate Loans (on which interest and principal
shall be payable contemporaneously with the related Euro-Dollar Loans of the
other Banks), and

    (b)  after each of its Euro-Dollar Loans has been repaid, all payments of
principal which would otherwise be applied to repay such Euro-Dollar Loans shall
be applied to repay its Base Rate Loans instead.

Section 9.3   Expenses; Indemnification.
              -------------------------      

    (a)  The Borrower shall pay (i) all reasonable out-of-pocket expenses of
the Lead Agent (including, without limitation, reasonable fees and disbursements
of special counsel Skadden, Arps, Slate, Meagher & Flom LLP, local counsel for
the Lead Agent, and travel, site visits, third party reports (including

    (b)  The Borrower agrees to indemnify the Lead Agent and each Bank, their
respective affiliates and the respective directors, officers, agents and
employees of the foregoing (each an "Indemnitee") and hold each Indemnitee
                                     ----------
harmless from and against any and all liabilities, losses, damages, costs and
expenses of any kind, including, without limitation, the reasonable fees and
disbursements of counsel and settlements and settlement costs, which may be
incurred by such Indemnitee in connection with any investigative, administrative
or judicial proceeding (whether or not such Indemnitee shall be

                                      101
<PAGE>
 
designated a party thereto) that may at any time (including, without limitation,
at any time following the payment of the Obligations) be imposed on, asserted
against or incurred by any Indemnitee as a result of, or arising out of, or in
any way related to or by reason of, (i) any of the transactions contemplated by
the Loan Documents or the execution, delivery or performance of any Loan
Document (including, without limitation, the Borrower's actual or proposed use
of proceeds of the Loans, whether or not in compliance with the provisions
hereof), (ii) any violation by the Borrower or the Environmental Affiliates of
any applicable Environmental Law, (iii) any Environmental Claim arising out of
the management, use, control, ownership or operation of property or assets by

(i) the gross negligence or willful misconduct of such Indemnitee as finally
determined by a court of competent jurisdiction or (ii) any investigative,
administrative or judicial proceeding imposed or asserted against any Indemnitee
by any bank regulatory agency or by any equity holder of such Indemnitee). The

    (c)  The Borrower shall pay, and hold the Lead Agent and each of the Banks
harmless from and against, any and all present and future U.S. stamp, recording,
transfer and other similar foreclosure related taxes with respect to the

Section 9.4   Sharing of Set-Offs.  In addition to any rights now or
              -------------------
hereafter granted under applicable law or otherwise, and not by way of
limitation of any such rights, upon the occurrence and during the continuance of
any Event of Default, each Bank is hereby authorized at any time or from time to
time, without presentment, demand, protest or other notice of any kind to the
Borrower or to any other Person, any such notice being hereby expressly waived,
to set off and to appropriate and apply any and all deposits (general or
special, time or demand, provisional or final), other than deposits held for the
benefit of third parties, and any other indebtedness at any time held or owing
by such Bank (including, without limitation, by branches and agencies of such
Bank wherever located) to or for the credit or the account of the Borrower
against and on account of the Obligations of the Borrower then due and payable
to such Bank under this Agreement or under any of the other Loan Documents,
including, without limitation, all interests in Obligations purchased by such
Bank. Each Bank agrees that if it shall, by exercising any right of set-off or
counterclaim or otherwise, receive payment of a proportion of the aggregate
amount of principal and interest due with respect to any Note held by it or
Letter of Credit participated in by it, or, in the case of the Fronting Bank,
Letter of Credit issued by it, which is greater than the proportion received by
any other Bank or Letter of Credit issued or participated in by such other Bank,
in respect of the aggregate amount of principal and interest due with respect to
any Note held by such other Bank, the Bank receiving such proportionately
greater payment shall purchase such participations in the Notes held by the
other Banks or Letter of Credit issued or participated in by such other Bank,
and such other adjustments shall be made, as may be required so that all such
payments of principal and interest with respect to the Notes held by the Banks
or Letter of Credit issued or participated in by such other Banks shall be
shared by the Banks pro rata; provided that nothing in this Section shall impair
                              --------
the right of any Bank to exercise any right of set-off or counterclaim it may
have and to apply the amount subject to such exercise to the payment of
indebtedness of the Borrower other than its indebtedness under the Notes or the
Letters of Credit. The Borrower agrees, to the fullest extent that it may
effectively do so under applicable law, that any holder of a participation in a
Note, whether or not acquired pursuant to the foregoing


                                      103
<PAGE>

arrangements, may exercise rights of set-off or counterclaim and other rights
with respect to such participation as fully as if such holder of a participation
were a direct creditor of the Borrower in the amount of such participation.

Section 9.5   Amendments and Waivers.  Any provision of this Agreement
              ----------------------
(including any of the financial covenants given by the Borrower pursuant to
Section 5.8), the Notes, the Letters of Credit or other Loan Documents may be
amended or waived if, but only if, such amendment or waiver is in writing and is
signed by the Borrower and the Required Banks (and, if the rights or duties of
the Lead Agent are affected thereby, by the Lead Agent); provided that no such
                                                         --------   
amendment or waiver shall, unless signed by all the Banks, (i) increase or
decrease the Commitment of any Bank (except for a ratable decrease in the
Commitments of all Banks) or subject any Bank to any additional obligation, (ii)
reduce the principal of or rate of interest on any Loan or any fees specified
herein, (iii) postpone the date fixed for any payment of principal of or
interest on any Loan or any fees hereunder or for any reduction or termination
of any Commitment, (iv) release the Guaranty or otherwise release any other
collateral, or (v) change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Notes, or the number of Banks, which shall be
required for the Banks or any of them to take any action under this Section or
any other provision of this Agreement. Notwithstanding the foregoing, no
amendment, waiver or consent shall, unless in writing and signed by the
Designating Lender on behalf of its Designated Lender affected thereby, (a)
subject such Designated Lender to any additional obligations, (b) reduce the
principal of, interest on, or other amounts due with respect to, the Designated
Lender Note made payable to such Designated Lender, or (c) postpone any date
fixed for any payment of principal of, or interest on, or other amounts due with
respect to the Designated Lender Note made payable to the Designated Lender.

Section 9.6  Successors and Assigns.
             ----------------------      

    (a)  The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns,
except that the Borrower may not assign or otherwise

                                      104
<PAGE>
 
transfer any of its rights under this Agreement or the other Loan Documents
without the prior written consent of all Banks.

    (b)  Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
                      -----------
any or all of its Loans. In the event of any such grant by a Bank of a
participating interest to a Participant, whether or not upon notice to the
Borrower and the Lead Agent, such Bank shall remain responsible for the
performance of its obligations hereunder, and the Borrower and the Lead Agent
shall continue to deal solely and directly with such Bank in connection with
such Bank's rights and obligations under this Agreement. Any agreement pursuant
to which any Bank may grant such a participating interest shall provide that
such Bank shall retain the sole right and responsibility to enforce the
obligations of the Borrower hereunder including, without limitation, the right
to approve any amendment, modification or waiver of any provision of this
Agreement; provided that such participation agreement may provide that such Bank
           --------
will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii), (iii) or (iv) of Section 9.5 without the consent
of the Participant. The Borrower agrees that each Participant shall, to the
extent provided in its participation agreement, be entitled to the benefits of
Article VIII with respect to its participating interest. An assignment or other
transfer which is not permitted by subsection (c) or (d) below shall be given
effect for purposes of this Agreement only to the extent of a participating
interest granted in accordance with this subsection (b).

(c)       Any Bank may at any time assign to one or more banks or other
institutions (each an "Assignee") all, or a proportionate part of all, of its
                       --------
rights and obligations under this Agreement, the Notes and the other Loan
Documents, and such Assignee shall assume such rights and obligations, pursuant
to an Assignment and Assumption Agreement in substantially the form of Exhibit D
                                                                       ---------
attached hereto executed by such Assignee and such transferor Bank, with (and
subject to) the subscribed consent of the Lead Agent, which consent shall not be
unreasonably withheld, and, provided no Event of Default shall have occurred and
be continuing, the Borrower, which consent shall not be unreasonably withheld or


                                      105
<PAGE>
 
delayed. Upon execution and delivery of such instrument and payment by such
Assignee to such transferor Bank of an amount equal to the purchase price agreed
between such transferor Bank and such Assignee, such Assignee shall be a Bank
party to this Agreement and shall have all the rights and obligations of a Bank
with a Commitment as set forth in such instrument of assumption, and the
transferor Bank shall be released from its obligations hereunder to a
corresponding extent, and no further consent or action by any party shall be
required. Upon the consummation of any assignment pursuant to this subsection
(c), the transferor Bank, the Lead Agent and the Borrower shall make appropriate
arrangements so that, if required, a new Note or Notes are issued to the
Assignee. In connection with any such assignment, the transferor Bank shall pay
to the Lead Agent an administrative fee for processing such assignment in the
amount of $2,500. If the Assignee is not incorporated under the laws of the
United States of America or a state thereof, it shall deliver to the Borrower
and the Lead Agent certification as to exemption from deduction or withholding
of any United States federal income taxes in accordance with Section 8.4.

    (d)  Any Bank (each, a "Designating Lender") may at any time designate one
                            ------------------
Designated Lender to fund Money Market Loans on behalf of such Designating
Lender subject to the terms of this Section 9.6(d) and the provisions in Section
9.6(b) and (c) shall not apply to such designation. No Bank may designate more
than one (1) Designated Lender. The parties to each such designation shall
execute and deliver to the Lead Agent for its acceptance a Designation
Agreement. Upon such receipt of an appropriately completed Designation Agreement
executed by a Designating Lender and a designee representing that it is a
Designated Lender, the Lead Agent will accept such Designation Agreement and
will give prompt notice thereof to the Borrower, whereupon, (i) the Borrower
shall execute and deliver to the Designating Bank a Designated Lender Note
payable to the order of the Designated Lender, (ii) from and after the effective
date specified in the Designation Agreement, the Designated Lender shall become
a party to this Agreement with a right (subject to the provisions of Section
2.3(b)) to make Money Market Loans on behalf of its Designating Lender pursuant
to Section 2.3 after the Borrower has accepted a Money Market Loan (or portion
thereof) of the

                                      106
<PAGE>
 
Designating Lender, and (iii) the Designated Lender shall not be required to
make payments with respect to any obligations in this Agreement except to the
extent of excess cash flow of such Designated Lender which is not otherwise
required to repay obligations of such Designated Lender which are then due and
payable; provided, however, that regardless of such designation and assumption
by the Designated Lender, the Designating Lender shall be and remain obligated
to the Borrower and the Banks for each and every of the obligations of the
Designating Lender and its related Designated Lender with respect to this
Agreement, including, without limitation, any indemnification obligations under
Section 7.6 hereof and any sums otherwise payable to the Borrower by the
Designated Lender. Each Designating Lender shall serve as the administrative
agent of the Designated Lender and shall on behalf of, and to the exclusion of,
the Designated Lender: (i) receive any and all payments made for the benefit of
the Designated Lender and (ii) give and receive all communications and notices
and take all actions hereunder, including, without limitation, votes, approvals,
waivers, consents and amendments under or relating to this Agreement and the
other Loan Documents. Any such notice, communication, vote, approval, waiver,
consent or amendment shall be signed by the Designating Lender as administrative
agent for the Designated Lender and shall not be signed by the Designated Lender
on its own behalf and shall be binding upon the Designated Lender to the same
extent as if signed by the Designated Lender on its own behalf. The Borrower,
the Lead Agent, and the Banks may rely thereon without any requirement that the
Designated Lender sign or acknowledge the same. No Designated Lender may assign
or transfer all or any portion of its interest hereunder or under any other Loan
Document, other than assignments to the Designating Lender which originally
designated such Designated Lender or otherwise in accordance with the provisions
of Section 9.6(b) and (c).

    (e)  Any Bank may at any time assign all or any portion of its rights under
this Agreement and its Note and the Letter(s) of Credit participated in by such
Bank or, in the case of the Fronting Bank, issued by it, to a Federal Reserve
Bank. No such assignment shall release the transferor Bank from its obligations
hereunder.

                                      107
<PAGE>
 

    (f)  No Assignee, Participant or other transferee of any Bank's rights
shall be entitled to receive any greater payment under Section 8.3 or 8.4 than
such Bank would have been entitled to receive with respect to the rights
transferred, unless such transfer is made with the Borrower's prior written
consent or by reason of the provisions of Section 8.2, 8.3 or 8.4 requiring such
Bank to designate a different Applicable Lending Office under certain
circumstances or at a time when the circumstances giving rise to such greater
payment did not exist.

Section 9.7   Governing Law; Submission to Jurisdiction.
              -----------------------------------------      

    (a)  THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND THE RIGHTS AND
OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN
ACCORDANCE WITH AND BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT
GIVING EFFECT TO THE PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW).

    (b)  Any legal action or proceeding with respect to this Agreement or any
other Loan Document and any action for enforcement of any judgment in respect
thereof may be brought in the courts of the State of New York or of the United
States of America for the Southern District of New York, and, by execution and
delivery of this Agreement, the Borrower hereby accepts for itself and in
respect of its property, generally and unconditionally, the non-exclusive
jurisdiction of the aforesaid courts and appellate courts from any thereof. The
Borrower irrevocably consents to the service of process out of any of the
aforementioned courts in any such action or proceeding by the hand delivery, or
mailing of copies thereof by registered or certified mail, postage prepaid, to
the Borrower at its address set forth below. The Borrower hereby irrevocably
waives any objection which it may now or hereafter have to the laying of venue
of any of the aforesaid actions or proceedings arising out of or in connection
with this Agreement or any other Loan Document brought in the courts referred to
above and hereby further irrevocably waives and agrees not to plead or claim in
any such court that any such action or proceeding brought in any such court has
been brought in an inconvenient forum. Nothing herein shall affect the right of
the Lead Agent, any Bank or any holder of a Note to serve process in any other
manner permitted by law or


                                      108
<PAGE>
 
to commence legal proceedings or otherwise proceed against the Borrower in any
other jurisdiction.

Section 9.8   Marshaling; Recapture.  Neither the Lead Agent nor any Bank
              ---------------------
shall be under any obligation to marshal any assets in favor of the Borrower or
any other party or against or in payment of any or all of the Obligations. To
the extent any Bank receives any payment by or on behalf of the Borrower, which
payment or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to the Borrower

          WHEREAS, this Assignment and Assumption Agreement (the "Assignment")
relates to the Revolving Credit Agreement dated as of ________ __, 199__ (the
"Loan Agreement") among the Borrower, the Assignor and the other Banks party
thereto, as Banks, and the Agent;

          WHEREAS, as provided under the Loan Agreement, the Assignor has a
Commitment to make Loans to the Borrower in an aggregate principal amount at any
time outstanding not to exceed $__________;

          WHEREAS, Loans made to the Borrower by the Assignor under the Loan

          WHEREAS, the Assignor proposes to assign to the Assignee all of the
rights of the Assignor under the Loan Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $__________ (the "Assigned Amount"),
together with a corresponding portion of its outstanding Loans, and the Assignee
proposes to accept assignment of such rights and assume the corresponding
obligations from the Assignor on such terms;

          NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

          SECTION 1.  Definitions.  All capitalized terms not otherwise defined

recourse to the Assignor.

          SECTION 3.  Payments.  As consideration for the assignment and sale
                      --------                                               
contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on the
date hereof in Federal funds the amount heretofore agreed between them./1/ It is
understood that Commitment Fees accrued to the date hereof are for the account
of the Assignor and such fees accruing from and including the date hereof are
for the account of the Assignee. Each of the Assignor and the Assignee hereby
agrees that if it receives any amount under the Loan Agreement which is for the
account of the other party hereto, it shall receive the same for the account of
such other party to the extent of such other party's interest therein and shall
promptly pay the same to such other party.

Pursuant to Section 9.6(c) the Borrower agrees to execute and deliver a Note
payable to the order of the Assignee to evidence the assignment and assumption
provided for herein.

          SECTION 5.  Non-Reliance on Assignor.  The Assignor makes no
                      ------------------------                        
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Borrower, or the validity and enforceability of the obligations of the Borrower
in respect of the Loan Agreement or any Note.  The Assignee acknowledges that it
has, independently and without reliance on the Assignor, and based on such
documents

/1/ The amount should combine principal together with accrued interest and
    breakage compensation, if any, to be paid by the Assignee, net of any
