organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation, and is duly qualified as a foreign corporation
and is in good standing in each jurisdiction in which such qualification is
required by law, other than those jurisdictions as to which the failure to be so
qualified or in good standing could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. Each of the Company
and its Subsidiaries has the corporate power and authority to own or hold under
lease the properties it purports to own or hold under lease, to transact the
business it transacts and proposes to transact, to execute and deliver the
Financing Documents to which it is a party and to perform the provisions
thereof.

         5.2     AUTHORIZATION, ETC.

                 (a) THE COMPANY. The Financing Documents to which the Company
         is a party have been duly authorized by all necessary corporate action
         on the part of the Company, and such Financing Documents constitute,
         legal, valid and binding obligations of the Company enforceable against
         the Company in accordance with their respective terms, except as such
         enforceability may be limited by

                           (i) applicable bankruptcy, insolvency,
                  reorganization, moratorium or other similar laws affecting the
                  enforcement of creditors' rights generally and

                          (ii) general principles of equity (regardless of
                 whether such enforceability is considered in a proceeding in

                 (b) THE SUBSIDIARIES. The Security Documents to which each
         Subsidiary is a party have been duly authorized by all necessary
         corporate action on the part of each

         and binding obligations of each such Subsidiary enforceable against

                           (ii) general principles of equity (regardless of
                  whether such enforceability is considered in a proceeding in
                  equity or at law).

         property of the Company or any Subsidiary under, any indenture,
         mortgage, deed of trust, loan, purchase or credit agreement, lease,
         corporate charter or by-laws, or any other agreement or instrument to

         conditions or provisions of any order, judgment, decree, or ruling of
         any court, arbitrator or Governmental Authority applicable to the

                 (c) violate any provision of any statute or other rule or
         regulation of any Governmental Authority applicable to the Company or

         expected to have a Material Adverse Effect.

                                5 REPRESENTATIONS AND WARRANTIES OF THE COMPANY



                 (b) Neither the Company nor any Subsidiary is in default under
         any term of any agreement or instrument to which it is a party or by
         which it is bound, or any order, judgment, decree or ruling of any
         court, arbitrator or Governmental Authority or is in violation of any
         applicable law, ordinance, rule or regulation (including without
         limitation Environmental Laws) of any Governmental Authority, which
         default or violation, individually or in the aggregate, could
         reasonably be expected to have a Material Adverse Effect.

         5.9     TAXES.

         The Company and its Subsidiaries have filed all tax returns that are
required to have been filed in any jurisdiction, and have paid all taxes shown
to be due and payable on such returns and all other taxes and assessments levied
upon them or their properties, assets, income or franchises, to the extent such
taxes and assessments have become due and payable and before they have become
delinquent, except for any taxes and assessments

                  (a) the amount of which is not individually or in the
         aggregate Material or

                 (b) the amount, applicability or validity of which is currently
         being contested in good faith by appropriate proceedings and with
         respect to which the Company or a Subsidiary, as the case may be, has
         established adequate reserves in accordance with GAAP.

The Company knows of no basis for any other tax or assessment that could
reasonably be expected to have a Material Adverse Effect. The charges, accruals
and reserves on the books of the Company and its Subsidiaries in respect of
Federal, state or other taxes for all fiscal periods are adequate. The Federal
income tax liabilities of the Company and its Subsidiaries have been paid for
all fiscal years up to and including the fiscal year ended December 31, 1995.

         5.10    TITLE TO PROPERTY; LEASES.

in Section 5.5 or purported to have been acquired by the Company or any
Subsidiary after said date (except as sold or otherwise disposed of in the
ordinary course of business), in each case free and clear of Liens prohibited by
this Agreement. All leases that individually or in the aggregate are Material
are valid and subsisting and are in full force and effect in all material
respects.

         5.11    LICENSES, PERMITS, ETC.

         patents, copyright, service marks, trademarks, trade names or rights
         thereto, that individually or in the aggregate are Material, without
         known conflict with the rights of others;

                 (b) to the reasonable knowledge of the Company, no product of
         the Company or any of its Subsidiaries infringes in any material
         respect any license, permit, franchise,

         authorization, patent, pending patent, copyright, service mark,
         trademark, trade name or other right owned by any other Person;

                 (c) to the reasonable knowledge of the Company, there is no
         Material violation by any Person of any right of the Company or any of
         its Subsidiaries with respect to any patent, pending patent, copyright,
         service mark, trademark, trade name or other right owned or used by the
         Company or any of its Subsidiaries; and

                 (d) all filings in federal and state offices (including,
         without limitation, the United States Patent and Trademark Office) in
         respect of all such patents, pending patents, copyrights, service
         marks, trademarks and tradenames, and licenses with respect thereto,
         necessary to protect the rights therein of the Company and its
         Subsidiaries against third parties, have been made.

         5.12    COMPLIANCE WITH ERISA.

                 (a) COMPLIANCE WITH LAW. The Company and each ERISA Affiliate
         have operated and administered each Plan in compliance with all
         applicable laws except for such instances of noncompliance as have not
         resulted in and could not reasonably be expected to result in a
         Material Adverse Effect. Neither the Company nor any ERISA Affiliate
         has incurred any liability pursuant to Title I or Title IV of ERISA or
         the penalty or excise tax provisions of the Code relating to employee
         benefit plans (as defined in section 3 of ERISA), and no event,
         transaction or condition has occurred or exists that could reasonably
         be expected to result in the incurrence of any such liability by the
         Company or any ERISA Affiliate, or in the imposition of any Lien on any
         of the rights, properties or assets of the Company or any ERISA
         Affiliate, in either case pursuant to Title I or Title IV of ERISA or
         to such penalty or excise tax provisions or to section 401(a)(29) or
         section 412 of the Code, other than such liabilities or Liens as would
         not be individually or in the aggregate Material.

                  (b) BENEFIT LIABILITIES. The present value of the aggregate
         benefit liabilities under each of the Plans (other than Multiemployer
         Plans), determined as of the end of such Plan's most recently ended
         plan year on the basis of the actuarial assumptions specified for
         funding purposes in such Plan's most recent actuarial valuation report,
         did not exceed the aggregate current value of the assets of such Plan
         allocable to such benefit liabilities by more than $600,000 in the
         aggregate for all Plans. The term "BENEFIT LIABILITIES" has the meaning
         specified in section 4001 of ERISA and the terms "CURRENT VALUE" and
         "PRESENT VALUE" have the meaning specified in section 3 of ERISA.

                 (c) WITHDRAWAL LIABILITIES. The Company and its ERISA
         Affiliates have not incurred withdrawal liabilities (and are not
         subject to contingent withdrawal liabilities) under section 4201 or
         4204 of ERISA in respect of Multiemployer Plans that individually or in
         the aggregate are Material.

                 (d) POSTRETIREMENT BENEFITS. The expected postretirement
         benefit obligation (determined as of the last day of the Company's most
         recently ended fiscal year in accordance with Financial Accounting
         Standards Board Statement No. 106, without regard to liabilities
         attributable to continuation coverage mandated by section 4980B of the
         Code) of the Company and its Subsidiaries is not Material.

                 (e) PROHIBITED TRANSACTIONS. The execution and delivery of the
         Financing Documents and the issuance and sale of the Notes hereunder
         will not involve any transaction that is subject to the prohibitions of
         section 406 of ERISA or in connection with which a tax could be imposed
         pursuant to section 4975(c)(1)(A) through section 4975(c)(1)(D),
         inclusive, of the Code. The representation by the Company in the first
         sentence of this Section 5.12(e) is made in reliance upon and subject
         to

                           (i) the accuracy of your representation in Section
                  6.2 as to the sources of the funds used to pay the purchase
                  price of the Notes to be purchased by you and

                          (ii) the assumption, made solely for the purpose of
                 making such representation, that Department of Labor Prohibited
                 Transaction Exemption 95-60 (60 FR 35925, July 12, 1995) with
                 respect to prohibited transactions remains valid in the
                 circumstances of the transactions contemplated herein.

         5.13    PRIVATE OFFERING BY THE COMPANY.

         Neither the Company nor anyone acting on its behalf has offered the
Notes or any similar securities for sale to, or solicited any offer to buy any
of the same from, or otherwise approached or negotiated in respect thereof with,
any Person other than you, the Other Purchasers and not more than 20 other
Institutional Investors, each of which has been offered the Notes at a private
sale for investment. Neither the Company nor anyone acting on its behalf has
taken, or will take, any action that would subject the issuance or sale of the
Notes to the registration requirements of section 5 of the Securities Act.

         5.14    USE OF PROCEEDS; MARGIN REGULATIONS.

         The Company will apply the proceeds of the sale of the Notes as set
forth in SCHEDULE 5.14. No part of the proceeds from the sale of the Notes
hereunder will be used, directly or indirectly, for the purpose of buying or
carrying any margin stock within the meaning of Regulation G of the Board of
Governors of the Federal Reserve System (12 CFR 207), or for the purpose of
buying or carrying or trading in any securities under such circumstances as to
involve the Company in a violation of Regulation X of said Board (12 CFR 224) or
to involve any broker or dealer in a violation of Regulation T of said Board (12
CFR 220). Margin stock does not constitute more than 5% of the value of the
consolidated assets of the Company and its Subsidiaries and the Company does not
have any present intention that margin stock will constitute more than 5% of the
value of such consolidated assets. As used in this Section, the terms "MARGIN
STOCK" and "PURPOSE OF BUYING OR CARRYING" shall have the meanings assigned to
them in said Regulation G.

         5.15    EXISTING INDEBTEDNESS; FUTURE LIENS.

                 (a) Except as described therein, SCHEDULE 5.15 sets forth a
         complete and correct list of all outstanding Indebtedness of the
         Company and its Subsidiaries as of the Closing Date (indicating as to
         each such Indebtedness the collateral, if any, securing such
         Indebtedness), since which date there has been no Material change in
         the amounts, interest rates, sinking funds, instalment payments or
         maturities of the Indebtedness of the Company or its Subsidiaries.
         Neither the Company nor any Subsidiary is in default and

                                5 REPRESENTATIONS AND WARRANTIES OF THE COMPANY



         no waiver of default is currently in effect, in the payment of any
         principal or interest on any Indebtedness of the Company or such
         Subsidiary and no event or condition exists with respect to any
         Indebtedness of the Company or any Subsidiary that would permit (or
         that with notice or the lapse of time, or both, would permit) one or
         more Persons to cause such Indebtedness to become due and payable
         before its stated maturity or before its regularly scheduled dates of
         payment.

                 (b) Except as disclosed in SCHEDULE 5.15, neither the Company
         nor any Subsidiary has agreed or consented to cause or permit in the
         future (upon the happening of a contingency or otherwise) any of its
         property, whether now owned or hereafter acquired, to be subject to a
         Lien not permitted by Section 10.3.

         5.16    FOREIGN ASSETS CONTROL REGULATIONS, ETC.

         The Company's use of the proceeds of the sale of the Notes will not
violate the Trading with the Enemy Act, as amended, or any of the foreign assets
control regulations of the United States Treasury Department (31 CFR, Subtitle
B, Chapter V, as amended) or any enabling legislation or executive order
relating thereto.

         5.17    STATUS UNDER CERTAIN STATUTES.

         Neither the Company nor any Subsidiary is subject to regulation under
the Investment Company Act of 1940, as amended, or the Public Utility Holding
Company Act of 1935, as amended.

         5.18    ENVIRONMENTAL MATTERS.

         Neither the Company nor any Subsidiary has knowledge of any claim or
has received any notice of any claim, and no proceeding has been instituted
raising any claim against the Company or any of its Subsidiaries or any of their
respective real properties now or formerly owned, leased or operated by any of
them or other assets, alleging any damage to the environment or violation of any
Environmental Laws, except, in each case, such as could not reasonably be
expected to result in a Material Adverse Effect. Except as otherwise disclosed
to you in writing,

                 (a) neither the Company nor any Subsidiary has knowledge of any
         facts which would give rise to any claim, public or private, of
         violation of Environmental Laws or damage to the environment emanating
         from, occurring on or in any way related to real properties now or
         formerly owned, leased or operated by any of them or to other assets or
         their use, except, in each case, such as could not reasonably be
         expected to result in a Material Adverse Effect;

                 (b) neither the Company nor any of its Subsidiaries has stored
         any Hazardous Materials on real properties now or formerly owned,
         leased or operated by any of them or disposed of any Hazardous
         Materials in a manner contrary to any Environmental Laws, in each case
         in any manner that could reasonably be expected to result in a Material
         Adverse Effect; and

         beneficiary of such plan (including any annuitant) are not affected in
         any manner by the investment performance of the separate account; or

         "qualified professional asset manager" or "QPAM" (within the meaning of
         Part V of the QPAM Exemption), no employee benefit plan's assets that
         are included in such investment fund, when combined with the assets of
         all other employee benefit plans established or maintained by the same
         employer or by an affiliate (within the meaning of section V(c)(1) of
         the QPAM Exemption) of such employer or by the same employee
         organization and managed by such QPAM, exceed 20% of the total client

                 (c) OFFER TO PREPAY NOTES. The offer to prepay Notes
         contemplated by Section 8.4(a) and Section 8.4(b) shall be an offer to
         prepay, in accordance with and subject to this Section 8.4, all, but
         not less than all, the Notes held by each holder (in this case only,
         "holder" in respect of any Note registered in the name of a nominee for
         a disclosed beneficial owner shall mean such beneficial owner)
         on a date specified in such offer (the "PROPOSED PREPAYMENT DATE"),
         without distinction between series. If such Proposed Prepayment Date is
         in connection with an offer contemplated by Section 8.4(a), such date
         shall be not less than 15 Business Days and not more than 20 Business
         Days after the date of such offer (if the Proposed Prepayment Date
         shall not be specified in such offer, the Proposed Prepayment Date
         shall be the 20th Business Day after the date of such offer).

                 (d) ACCEPTANCE; REJECTION. A holder of Notes may accept the
         offer to prepay made pursuant to this Section 8.4 by causing a notice
         of such acceptance to be delivered to the Company at least 2 days prior
         to the Proposed Prepayment Date. A failure by a holder of Notes to
         respond to an offer to prepay made pursuant to this Section 8.4 shall
         be deemed to constitute an acceptance of such offer by such holder.

                 (e) PREPAYMENT. Prepayment of the Notes to be prepaid pursuant
         to this Section 8.4 shall be at 100% of the principal amount of such
         Notes, plus, subject to Section 8.4(h), the Make-Whole Amount
         determined for the date of prepayment with respect to such principal
         amount, together with interest on such Notes accrued to the date of
         prepayment. On the Business Day preceding the date of prepayment, the
         Company shall deliver to each holder of Notes being prepaid a statement
         showing the Make-Whole Amount, if any, due in connection with such
         prepayment and setting forth the details of the computation of such
         amount. The prepayment shall be made on the Proposed Prepayment Date
         except as provided in Section 8.4(f).

                 (f) DEFERRAL PENDING CHANGE IN CONTROL. The obligation of the
         Company to prepay Notes pursuant to the offers accepted in accordance
         with Section 8.4(d) is subject to the occurrence of the Change in
         Control in respect of which such offers and acceptances shall have been
         made. In the event that such Change in Control does not occur on the
         Proposed Prepayment Date in respect thereof, the prepayment shall be
         deferred until and shall be made on the date on which such Change in
         Control occurs. The Company shall keep each holder of Notes reasonably
         and timely informed of

                           (i) any such deferral of the date of prepayment,

                           (ii) the date on which such Change in Control and the
                  prepayment are expected to occur, and

                           (iii) any determination by the Company that efforts
                  to effect such Change in Control have ceased or been abandoned
                  (in which case the offers and acceptances made pursuant to
                  this Section 8.4 in respect of such Change in Control shall be
                  deemed rescinded).

                 (g) OFFICER'S CERTIFICATE. Each offer to prepay the Notes
         pursuant to this Section 8.4 shall be accompanied by a certificate,
         executed by a Senior Financial Officer of the Company and dated the
         date of such offer, specifying:

                  such computation, or that no Make-Whole Amount is due
                  pursuant to Section 8.4(h), with supporting detail;

                  Date;

                           (vii) that the conditions of this Section 8.4 have

         connection therewith.

         the principal of the Notes made pursuant to this Section 8.4 shall be
         applied against and reduce each of the then remaining principal
         payments due pursuant to Section 8.1 by a percentage equal to the
         aggregate principal amount of the Notes so paid divided by the

                 principal amount of all Notes outstanding immediately prior to
                 the making of such offer) and the principal amount of each Note
                 offered to be prepaid on such Prepayment Date,

                          (vi) specify the amount of interest that would be due

         payment, a holder of Notes shall cause a notice of such acceptance or

         acceptance of such offer.

                 (c) PAYMENT. The Company shall pay to each holder which shall
         have accepted such offer a principal amount equal to such holder's

         Date, if any, and interest thereon accrued to such Prepayment Date,
         shall become due and payable on such Prepayment Date. Two Business Days

         amount of principal of such holder's Notes to be paid and specifying
         the details of the calculation of such Make-Whole Amount as of the
         Prepayment Date, and including a copy of the source of interest rate
         information used in the calculation thereof. The Company shall,
         promptly after making such payment, notify in writing all holders of
         Notes of the payment amount, and the name of each holder, of any Notes
         prepaid under this Section 8.5.

                 (d) EFFECT ON REQUIRED PAYMENTS. The amount of each payment of
         the principal of the Notes made pursuant to this Section 8.5 shall be

         percentage equal to the aggregate principal amount of the Notes so paid
         divided by the aggregate principal amount of the Notes outstanding
         immediately prior to such payment.

         8.6     ALLOCATION OF PARTIAL PREPAYMENTS.

         In the case of each partial prepayment of the Notes pursuant to Section
8.1, Section 8.2 and Section 8.3, the principal amount of the Notes to be
prepaid shall be allocated among all of the Notes (without regard to series) at
the time outstanding in proportion, as nearly as practicable, to the respective
unpaid principal amounts thereof not theretofore called for prepayment.

         8.7     MATURITY; SURRENDER, ETC.

         In the case of each prepayment of Notes pursuant to this Section 8, the
principal amount of each Note to be prepaid shall mature and become due and
payable on the date fixed for such prepayment, together with interest on such
principal amount accrued to such date and the applicable Make-Whole Amount, if
any. From and after such date, unless the Company shall fail to pay such
principal amount when so due and payable, together with the interest and
Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall
cease to accrue. Any Note paid or prepaid in full shall be surrendered to the
Company and cancelled and shall not be reissued, and no Note shall be issued in
lieu of any prepaid principal amount of any Note.

         8.8     PURCHASE OF NOTES.

         The Company will not and will not permit any Affiliate to purchase,
redeem, prepay or otherwise acquire, directly or indirectly, any of the
outstanding Notes except upon the payment or prepayment of the Notes in
accordance with the terms of this Agreement and the Notes. The Company will
promptly cancel all Notes acquired by it or any Affiliate pursuant to any
payment, prepayment or purchase of Notes pursuant to any provision of this
Agreement and no Notes may be issued in substitution or exchange for any such
Notes.

         8.9     MAKE-WHOLE AMOUNT.

         The term "MAKE-WHOLE AMOUNT" means, with respect to any Note, an amount
equal to the excess, if any, of the Discounted Value of the Remaining Scheduled
Payments with respect to the Called Principal of such Note over the amount of
such Called Principal, provided that the Make-Whole Amount may in no event be
less than zero. For the purposes of determining the Make-Whole Amount, the
following terms have the following meanings:

                 "CALLED PRINCIPAL" means, with respect to any Note, the
         principal of such Note that is to be prepaid pursuant to the terms
         hereof or has become or is declared to be immediately due and payable
         pursuant to Section 12.1, as the context requires.

                 "DISCOUNTED VALUE" means, with respect to the Called Principal
         of any Note, the amount obtained by discounting all Remaining Scheduled
         Payments with respect to such Called Principal from their respective
         scheduled due dates to the Settlement Date with respect to such Called
         Principal, in accordance with accepted financial practice and at a
         discount factor (applied on the same periodic basis as that on which
         interest on the Notes is payable) equal to the Reinvestment Yield with
         respect to such Called Principal.

                 "MARGIN" means, the case of a prepayment made in connection
         with Section 8.4, 1% per annum, and in all other cases, 0.60% per
         annum.

                 "REINVESTMENT YIELD" means, with respect to the Called
         Principal of any Note, the Margin plus the yield to maturity implied by

                          (i) the yields reported, as of 10:00 A.M. (New York
                 City time) on the second Business Day preceding the Settlement
                 Date with respect to such Called Principal, on the display
                 designated as "Page USD" on the Bloomberg Financial Markets
                 System (or such other display as may replace Page USD on the
                 Bloomberg Financial Markets System) for actively traded U.S.
                 Treasury securities having a maturity equal to the Remaining
                 Average Life of such Called Principal as of such Settlement
                 Date, or

                          (ii) if such yields are not reported as of such time
                 or the yields reported as of such time are not ascertainable,
                 the Treasury Constant Maturity Series Yields reported, for the
                 latest day for which such yields have been so reported as of
                 the second Business Day preceding the Settlement Date with
                 respect to such Called Principal, in Federal Reserve
                 Statistical Release H.15 (519) (or any comparable successor
                 publication) for actively traded U.S. Treasury securities
                 having a constant maturity equal to the Remaining Average Life
                 of such Called Principal as of such Settlement Date.

         Such implied yield will be determined, if necessary, by

                           (a) converting U.S. Treasury bill quotations to
                  bond-equivalent yields in accordance with accepted financial
                  practice and

                           than the Remaining Average Life and

                 "REMAINING AVERAGE LIFE" means, with respect to any Called
         Principal, the number of years (calculated to the nearest one-twelfth
         year) obtained by dividing

                           (i) such Called Principal into

                           (ii) the sum of the products obtained by multiplying

                                    (a) the principal component of each
                           Remaining Scheduled Payment with respect to such

                 "REMAINING SCHEDULED PAYMENTS" means, with respect to the
         Called Principal of any Note, all payments of such Called Principal and
         interest thereon that would be due after the Settlement Date with
         respect to such Called Principal if no payment of such Called Principal
         were made prior to its scheduled due date, provided that if such
         Settlement Date is not a date on which interest payments are due to be
         made under the terms of the Notes, then the amount of the next
         succeeding scheduled interest payment will be reduced by the amount of
         interest accrued to such Settlement Date and required to be paid on
         such Settlement Date.

                 "SETTLEMENT DATE" means, with respect to the Called Principal
         of any Note, the date on which such Called Principal is to be prepaid

         requires.

         The Company will, and will cause each of its Subsidiaries to, comply
with all laws, ordinances or governmental rules or regulations to which each of
them is subject, including, without limitation, Environmental Laws, and will
obtain and maintain in effect all licenses, certificates, permits, franchises
and other governmental authorizations necessary to the ownership of their
respective properties or to the conduct of their respective businesses, in each
case to the extent necessary to ensure that non-compliance with such laws,
ordinances or governmental rules or regulations or failures to obtain or
maintain in effect such licenses, certificates, permits, franchises and other
governmental authorizations could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

         9.2     INSURANCE.

         The Company will, and will cause each of its Subsidiaries to, maintain,
with financially sound and reputable insurers, insurance with respect to their
respective properties and businesses against such casualties and contingencies,
of such types, on such terms and in such amounts (including deductibles,
co-insurance and self-insurance, if adequate reserves are maintained with
respect thereto) as is customary in the case of entities of established
reputations engaged in the same or a similar business and similarly situated.

         9.3     MAINTENANCE OF PROPERTIES.

         The Company will, and will cause each of its Subsidiaries to, maintain
and keep, or cause to be maintained and kept, their respective properties in

that the business carried on in connection therewith may be properly conducted
at all times, provided that this Section shall not prevent the Company or any
Subsidiary from discontinuing the operation and the maintenance of any of its

and the Company has concluded that such discontinuance could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.

         9.4     PAYMENT OF TAXES AND CLAIMS.

         The Company will, and will cause each of its Subsidiaries to, file all
tax returns required to be filed in any jurisdiction and to pay and discharge
all taxes shown to be due and payable on such returns and all other taxes,
assessments, governmental charges, or levies imposed on them or any of their

assessments have become due and payable and before they have become delinquent
and all claims for which sums have become due and payable that have or might
become a Lien on properties or assets of the Company or any Subsidiary, provided
that neither the Company nor any Subsidiary need pay any such tax or assessment
or claims if

                 (a) the amount, applicability or validity thereof is contested
         by the Company or such Subsidiary on a timely basis in good faith and
         in appropriate proceedings, and the Company or such Subsidiary has
         established adequate reserves therefor in accordance with GAAP on the
         books of the Company or such Subsidiary or

                 (b) the nonpayment of all such taxes and assessments in the
         aggregate could not reasonably be expected to have a Material Adverse
         Effect.

         9.5     CORPORATE EXISTENCE, ETC.

         The Company will at all times preserve and keep in full force and
effect its corporate existence. Subject to Section 10.2, the Company will at all
times preserve and keep in full force and effect the corporate existence of each
of its Subsidiaries (unless merged into the Company or a Subsidiary) and all
rights and franchises of the Company and its Subsidiaries unless, in the good
faith judgment of the Company, the termination of or failure to preserve and
keep in full force and effect such corporate existence, right or franchise could
not, individually or in the aggregate, have a Material Adverse Effect.

         9.6     LINE OF BUSINESS.

         The Company will not, and will not permit any of its Subsidiaries to,
engage in any business if, as a result, the general nature of the business in
which the Company and its Subsidiaries, taken as a whole, would then be engaged
would be substantially changed from the general nature of the business in which
the Company and its Subsidiaries, taken as a whole, are engaged on the date of
this Agreement as described in the Disclosure Materials.

         9.7     SUBSIDIARY SECURITY DOCUMENTS.

         The Company will cause each Person which becomes a direct or indirect
Subsidiary of the Company to duly authorize, execute and deliver to each holder
of Notes all Security Documents that in the opinion of the Required Holders or

         The Company will not, and will not permit any of its Subsidiaries to,
consolidate with or merge with any other Person or convey, transfer or lease
substantially all of its assets in a single transaction or series of
transactions to any Person, provided that such prohibition shall not apply to
the Company if:

                 (a) the successor formed by such consolidation or the survivor
         of such merger or the Person that acquires by conveyance, transfer or
         lease substantially all of the assets of the Company as an entirety
         (the "SURVIVOR"), as the case may be, shall be a solvent corporation
         organized and existing under the laws of the United States or any State
         thereof (including the District of Columbia), and

                 (b) if the Company is not such corporation, the Survivor and
         each of its Subsidiaries shall have

                           (i) executed and delivered to each holder of any
                  Notes its assumption of the due and punctual performance and
                  observance of each covenant and condition of the Financing
                  Documents to which it is a party, and

                           (ii) caused to be delivered to each holder of any
                  Notes an opinion of independent counsel reasonably
                  satisfactory to the Required Holders, to the effect that all
                  agreements or instruments effecting such assumption are
                  enforceable in accordance with their terms and comply with the
                  terms hereof (subject to customary exceptions and
                  limitations), and

                 (c) immediately after giving effect to such transaction, no
         Default or Event of Default shall have occurred and be continuing and
         the Survivor would be permitted under Section 10.5(a)(iii) to incur $1
         of Funded Debt not owing to one of its Subsidiaries;

and provided further that any of the Company's Subsidiaries may merge with the
Company so long as the Company is the survivor of such merger, and any of the
Company's Subsidiaries may merge with another of the Company's Subsidiaries. No
such conveyance, transfer or lease of substantially all of the assets of the
Company or any Subsidiary shall have the effect of releasing the Company, any
such Subsidiary or any successor corporation that shall theretofore have become
such in the manner prescribed in this Section 10.2 from its liability under the
Financing Documents.

         Lien on or with respect to any property or asset (including, without
         limitation, any document or instrument in respect of goods or accounts
         receivable) of the Company or any such Subsidiary, whether now owned or
         held or hereafter acquired, or any income or profits therefrom (whether

         that, and with such priority as, the Secured Obligations may be
         entitled under applicable law, of an equitable Lien on such property.
         Such violation of Section 10.3(a) will constitute an Event of Default,

         Except as permitted under Section 10.2, the Company will not, and will
not permit any of its Subsidiaries to, make any Asset Disposition unless:

                  (a) such Asset Disposition is the JV Transfer; or

                  (b) (i) in the good faith opinion of the Company, the Asset
                  Disposition is in exchange for consideration having a Fair

                  and is in the best interest of the Company or such Subsidiary;

                      (ii) immediately after giving effect to the Asset
                  Disposition, no Default or Event of Default would exist; and

                  the subject of any Asset Disposition (other than the JV
                  Transfer) occurring in the then current fiscal year of the

                  the subject of any Asset Disposition (other than the JV
                  Transfer) occurring on or after the Closing Date would not
                  exceed 25% of Consolidated Assets as of the end of the then
                  most recently ended fiscal quarter of the Company.

If, and solely to the extent that, the Net Proceeds Amount for any Asset
Disposition is applied to a Debt Prepayment Application or a Property
Reinvestment Application within 365 days after such Asset Disposition, then such
Asset Disposition, only for the purpose of determining compliance with Section
10.7(b)(iii) as of any date, shall to the extent of such application be deemed
not to be an Asset Disposition.

injunction against a violation of any of the terms hereof or thereof, or in aid
of the exercise of any power granted hereby or thereby or by law or otherwise.

to clause (b) or clause (c) of Section 12.1, the holders of more than 50% in
principal amount of the Notes then outstanding, by written notice to the

                  (a) the costs and expenses incurred in enforcing or defending
         (or determining whether or how to enforce or defend) any rights under
         the Financing Documents or in

         responding to any subpoena or other legal process or informal
         investigative demand issued in connection with the Financing Documents
         or by reason of being a holder of any Note, and

                  (b) the costs and expenses, including financial advisors'
         fees, incurred in connection with the insolvency or bankruptcy of the

The Company will pay, and will save you and each other holder of a Note harmless
from, all claims in respect of any fees, costs or expenses if any, of brokers
and finders (other than those retained by you).

         15.2 SURVIVAL.

         The obligations of the Company under this Section 15 will survive the
payment or transfer of any Note, the enforcement, amendment or waiver of any
provision of any Financing Document, and the termination of this Agreement.

16. SURVIVAL OF REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT.

         All representations and warranties contained in any Financing Document
shall survive the execution and delivery of this Agreement and the Notes, the
purchase or transfer by you of any Note or portion thereof or interest therein
and the payment of any Note, and may be relied upon by any subsequent holder of
a Note, regardless of any investigation made at any time by or on behalf of you
or any other holder of a Note. All statements contained in any certificate or
other instrument delivered by or on behalf of the Company pursuant to any
Financing Document shall be deemed representations and warranties of the Company
under this Agreement. Subject to the preceding sentence, the Financing Documents
embody the entire agreement and understanding between you and the Company and
supersede all prior agreements and understandings relating to the subject matter
hereof.

17. AMENDMENT AND WAIVER.

         17.1 REQUIREMENTS.

         This Agreement and the Notes may be amended, and the observance of any
term hereof or of the Notes may be waived (either retroactively or
prospectively), with (and only with) the written consent of the Company and the
Required Holders, except that

                  (a) no amendment or waiver of any of the provisions of Section
         1 through Section 6, inclusive, or Section 21, or any defined term (as
         it is used therein), will be effective as to you unless consented to by
         you in writing, and

                  (b) no such amendment or waiver may, without the written
         consent of the holder of each Note at the time outstanding affected
         thereby,

                           (i) subject to the provisions of Section 12 relating
                  to acceleration or rescission, change the amount or time of
                  any prepayment or payment of principal

                  of, or reduce the rate or change the time of payment or method
                  of computation of interest or of the Make-Whole Amount on, the
                  Notes,

                           (ii) change the percentage of the principal amount of
                  the Notes the holders of which are required to consent to any
                  such amendment or waiver, or

                           (iii) amend any of Section 8, Section 11(a), Section
                  11(b), Section 12, Section 17 or Section 20.

         17.2 SOLICITATION OF HOLDERS OF NOTES.

                 (a) SOLICITATION. The Company will provide each holder of the
         Notes (irrespective of the amount of Notes then owned by it) with
         sufficient information, at least 30 days in advance of the date a
         decision is required, in order to enable such holder to make an
         informed and considered decision with respect to any proposed
         amendment, waiver or consent in respect of any of the provisions hereof
         or of the Notes. The Company will deliver executed or true and correct
         copies of each amendment, waiver or consent effected pursuant to the
         provisions of this Section 17 to each holder of outstanding Notes
         promptly following the date on which it is executed and delivered by,
         or receives the consent or approval of, the requisite holders of Notes.

                 (b) PAYMENT. The Company will not directly or indirectly pay or
         cause to be paid any remuneration, whether by way of supplemental or
         additional interest, fee or otherwise, or grant any security, to any
         holder of Notes as consideration for or as an inducement to the
         entering into by any holder of Notes or any waiver or amendment of any
         of the terms and provisions hereof unless such remuneration is
         concurrently paid, or security is concurrently granted, on the same
         terms, ratably to each holder of Notes then outstanding even if such
         holder did not consent to such waiver or amendment.

         17.3 BINDING EFFECT, ETC.

         Any amendment or waiver consented to as provided in this Section 17
applies equally to all holders of Notes and is binding upon them and upon each
future holder of any Note and upon the Company without regard to whether such
Note has been marked to indicate such amendment or waiver. No such amendment or
waiver will extend to or affect any obligation, covenant, agreement, Default or
Event of Default not expressly amended or waived or impair any right consequent
thereon. No course of dealing between the Company and the holder of any Note nor
any delay in exercising any rights hereunder or under any Note shall operate as
a waiver of any rights of any holder of such Note. As used herein, the term
"THIS AGREEMENT" and references thereto shall mean this Agreement as it may from
time to time be amended or supplemented.

         17.4 NOTES HELD BY COMPANY, ETC.

         Solely for the purpose of determining whether the holders of the
requisite percentage of the aggregate principal amount of Notes then outstanding
approved or consented to any amendment, waiver or consent to be given under any
Financing Document, or have directed the taking of any action provided herein or
in the Notes to be taken upon the direction of the holders of a specified
percentage of the aggregate principal amount of Notes then outstanding, Notes

limitation,

original, or from introducing evidence to demonstrate the inaccuracy of any such
reproduction.

20. CONFIDENTIAL INFORMATION

         For the purposes of this Section 20, "CONFIDENTIAL INFORMATION" means
information delivered to you by or on behalf of the Company or any Subsidiary in
connection with the transactions contemplated by or otherwise pursuant to this
Agreement that is proprietary in nature and that was clearly marked or labeled
or otherwise adequately identified when received by you as being confidential
information of the Company or such Subsidiary, provided that such term does not
include information that

                  (a) was publicly known or otherwise known to you prior to the
         time of such disclosure,

                  (b) subsequently becomes publicly known through no act or
         omission by you or any person acting on your behalf,

                  (c) otherwise becomes known to you other than through

                  (d) constitutes financial statements delivered to you under
         Section 7.1 that are otherwise publicly available.

You will maintain the confidentiality of such Confidential Information in
accordance with procedures adopted by you in good faith to protect confidential
information of third parties delivered to you, provided that you may deliver or
disclose Confidential Information to

                  (i) your directors, officers, employees, agents, attorneys and
         affiliates (to the extent such disclosure reasonably relates to the
         administration of the investment represented by your Notes),

                  (ii) your financial advisors and other professional advisors
         who agree to hold confidential the Confidential Information
         substantially in accordance with the terms of this Section 20,

                  (iii) any other holder of any Note,

                  (iv) any Institutional Investor to which you sell or offer to
         sell such Note or any part thereof or any participation therein (if
         such Person has agreed in writing prior to its receipt of such
         Confidential Information to be bound by the provisions of this Section
         20),

                  (v) any Person from which you offer to purchase any security
         of the Company (if such Person has agreed in writing prior to its
         receipt of such Confidential Information to be bound by the provisions
         of this Section 20),

                  (vi) any federal or state regulatory authority having
         jurisdiction over you,

                  (vii) the National Association of Insurance Commissioners or
         any similar organization, or any nationally recognized rating agency
         that requires access to information about your investment portfolio or

                  (viii) any other Person to which such delivery or disclosure
         may be necessary or appropriate

                           (A) to effect compliance with any law, rule,
                  regulation or order applicable to you,

                           (B) in response to any subpoena or other legal
                  process,

                           (C) in connection with any litigation to which you
                  are a party or

                           (D) if an Event of Default has occurred and is
                  continuing, to the extent you may reasonably determine such
                  delivery and disclosure to be necessary or appropriate in the
                  enforcement or for the protection of the rights and remedies
                  under your Notes and this Agreement,

         provided that you will use reasonable efforts to give the Company prior
         notice of such disclosure and will not object to the Company's efforts
         to obtain confidential treatment of the disclosed information in any
         such proceeding.

Each holder of a Note, by its acceptance of a Note, will be deemed to have
agreed to be bound by and to be entitled to the benefits of this Section 20 as
though it were a party to this Agreement. On reasonable request by the Company
in connection with the delivery to any holder of a Note of information required
to be delivered to such holder under this Agreement or requested by such holder
(other than a holder that is a party to this Agreement or its nominee), such
holder will enter into an agreement with the Company embodying the provisions of
this Section 20.

21. SUBSTITUTION OF PURCHASER

         You shall have the right to substitute any one of your Affiliates as
the purchaser of the Notes that you have agreed to purchase hereunder, by
written notice to the Company, which notice shall be signed by both you and such
Affiliate, shall contain such Affiliate's agreement to be bound by this
Agreement and shall contain a confirmation by such Affiliate of the accuracy
with respect to it of the representations set forth in Section 6. Upon receipt
of such notice, wherever the word "you" is used in this Agreement (other than in
this Section 21), such word shall be deemed to refer to such Affiliate in lieu
of you. In the event that such Affiliate is so substituted as a purchaser
hereunder and such Affiliate thereafter transfers to you all of the Notes then
held by such Affiliate, upon receipt by the Company of notice of such transfer,
wherever the word "you" is used in this Agreement (other than in this Section
21), such word shall no longer be deemed to refer to such Affiliate, but shall
refer to you, and you shall have all the rights of an original holder of the
Notes under this Agreement.

22. MISCELLANEOUS

         22.1 SUCCESSORS AND ASSIGNS.

         All covenants and other agreements contained in any Financing Document
by or on behalf of any of the parties hereto bind and inure to the benefit of
their respective successors and assigns (including, without limitation, any
subsequent holder of a Note) whether so expressed or not.

         22.2 PAYMENTS DUE ON NON-BUSINESS DAYS.

         Anything in this Agreement or the Notes to the contrary
notwithstanding, any payment of principal of or Make-whole Amount or interest on
any Note that is due on a date other than a Business Day shall be made on the
next succeeding Business Day without including the additional days elapsed in
the computation of the interest payable on such next succeeding Business Day.

         22.3 SEVERABILITY.

         Any provision of this Agreement that is prohibited or unenforceable in
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall (to the full extent permitted by law) not invalidate or
render unenforceable such provision in any other jurisdiction.

         22.4 CONSTRUCTION.

         Each covenant contained herein shall be construed (absent express
provision to the contrary) as being independent of each other covenant contained
herein, so that compliance with any one covenant shall not (absent such an
express contrary provision) be deemed to excuse compliance with any other
covenant. Where any provision herein refers to action to be taken by any Person,
or which such Person is prohibited from taking, such provision shall be
applicable whether such action is taken directly or indirectly by such Person.

         22.5 COUNTERPARTS.

         This Agreement may be executed in any number of counterparts, each of
which shall be an original but all of which together shall constitute one
instrument. Each counterpart may consist of a number of copies hereof, each
signed by less than all, but together signed by all, of the parties hereto.
