         3.1.     Interest Rate; Payment; Usury.

                  (a) Provided that no Event of Default has occurred and is
         continuing and subject to the other provisions of this Agreement (i)
         during the period from and including the Closing Date to, but not
         including, the third month anniversary of the Closing Date, the Loan
         shall bear interest at the rate of ten percent (10%) per annum; (ii)
         from and including the third month anniversary of the Closing Date
         through the sixth month anniversary of the Closing Date, the Loan shall
         bear interest at the rate of eleven percent (11%) per annum; and (iii)
         during each monthly period (or portion thereof) from and after the
         sixth month anniversary of the Closing Date until the principal and all
         accrued


                                       4
   5

         interest on the Loan have been paid, the Loan shall bear interest at a
         rate that is fifty basis points (.5 of 1%) higher than the rate in
         effect immediately prior to the commencement of such monthly period.
         During any period that an Event of Default shall have occurred and be
         continuing, interest on the Loan shall accrue at a rate equal to the
         otherwise applicable interest rate plus five hundred basis points (the
         "Default Interest Rate"). Notwithstanding anything contained herein to
         the contrary, in no event shall the interest rate on the Loan,
         including the Default Interest Rate, exceed the highest rate permitted
         by applicable law. Interest on the Loan, including interest at the
         Default Rate, shall be based on a 360 day year and interest shall
         accrue and be payable for the actual number of calendar days elapsed.
         Interest shall be payable in arrears commencing on the third month
         anniversary of the Closing Date and on the same day of each subsequent
         month until the principal and all accrued interest have been paid in
         full.

                  (b) It is the intention of the Company and Lenders to conform
         strictly to applicable usury laws now or hereafter in force, and any
         interest payable under this Agreement or the Notes shall be subject to
         reduction to an amount not to exceed the maximum non-usurious amount
         for commercial loans allowed under such applicable usury laws as now or
         hereafter construed by the courts having jurisdiction over such
         matters. In the event such interest (whether designated as interest,
         service charges, points, or otherwise) does exceed the maximum legal
         rate, it shall be (i) canceled automatically to the extent that such
         interest exceeds the maximum legal rate; (ii) if already paid, at the
         option of each Holder, either be rebated to the Company or credited on
         the principal amount of the Loan evidenced by the Note held by such
         Holder; or (iii) if the Loans have been prepaid in full, then such
         excess shall be rebated to the Company. It is further agreed, without
         limitation of the foregoing, that all calculations of the rate of
         interest contracted for, charged, or received under this Agreement and
         the Notes that are made for the purpose of determining whether such
         rate exceeds the maximum legal rate, shall be made, to the extent
         permitted by applicable law, by amortizing, prorating, allocating, and
         spreading throughout the full stated term of the Loans (and any
         extensions of the term thereof that may be hereafter granted) all such
         interest at any time contracted for, charged, or received from the
         Company or otherwise by the Holders so that the rate of interest on
         account of the Loans, as so calculated is uniform throughout the term
         thereof. If the Company is exempt or hereafter becomes exempt from
         applicable usury statutes or for any other reason the rate of interest
         to be charged on the Loan is not limited by law, none of the provisions
         of this paragraph shall be construed so as to limit or reduce the
         interest or other consideration payable under this Agreement or the
         Notes or under the instrument securing payment thereof. The terms and
         provisions of this paragraph shall control and supersede every other
         provision of all agreements between the parties hereto.

         3.2.     Maturity.

                           (a) Maturity Date. Unless the same shall become due
                  earlier as a result of acceleration of the maturity, the Loans
                  shall mature on the six (6) month anniversary of the Closing
                  Date, at which time the outstanding principal balance of the
                  Loans and all accrued and unpaid interest shall become due and
                  payable.

                           (b) Extension. At any time prior to the six month
                  anniversary date of the Closing Date and upon not less than
                  five (5) days prior written notice to the Holders and provided
                  that no Default or Event of Default then exists and is
                  continuing, the Company may extend the original maturity date
                  of all and not less than all of the Loans and Notes for one
                  (1) additional six (6) month period ending on the one year
                  anniversary of the Closing Date.

         3.3.     Prepayments. The Company may from time to time prepay the
Loans, in whole or in part, at any time. Any partial prepayment shall be applied
first to interest which is accrued and unpaid and then to principal.

         3.4.     Manner of Payment; Pro Rata Payments. The Company shall make
payments in respect of the Loans (including principal and interest) by wire
transfer of immediately available funds to the account specified by the Holders.
Notwithstanding any other provision in this Agreement or the Notes, the Company
covenants and agrees and the Lenders among themselves agree that all payments
made by the Company of interest and principal, including any prepayments, shall
be made to and for the benefit of the Holders pro rata according the outstanding
principal balance of their respective Notes.

         3.5.     Events of Default. Each of the following constitutes an
"Event of Default":

                  (i) default for five (5) days in the payment when due of

         additional time as is necessary to effect such cure (not to exceed 30
         days);

                  (v) failure by the Company for 30 days after notice from the

         3.6.     Acceleration.

                  (a) Declaration of Acceleration. If any Event of Default
         occurs and is continuing, a Holder may, upon notice to the Company,
         declare the Note held by it to be due and payable immediately; and upon
         any such declaration all principal and interest on such Note shall
         become immediately due and payable; provided, however, in the case of
         an Event of Default arising from any event described in clauses (ix) or
         (x) of Section 3.5 hereof, all of the Loans and Notes shall ipso facto
         become due and payable without further action or notice on the part of
         the Holders.

                  (b) Rescission. At any time after a declaration of
         acceleration with respect to a Note, the Holder thereof may, in its
         sole discretion, rescind and cancel such declaration and its
         consequences. No such rescission shall affect any subsequent Default or
         impair any right with respect thereto.

         3.7. Other Remedies. If an Event of Default occurs and is continuing, a
Holder may pursue any available remedy to collect the payment of principal and
interest (including interest at the Default Interest Rate) on the Note held by
it or to enforce the performance of any provision of such Note or this
Agreement. A delay or omission by a Holder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

         3.8. Waiver Of Past Defaults. A Holder may waive any existing Default
or Event of Default and its consequences under this Agreement. Upon any such
waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Agreement; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

         3.9. Priorities. Any sums collected by a Holder hereunder or under a
Note held by it shall be applied first to all costs and expenses of collection,
including reasonable attorneys' fees, then, subject to the provisions of Section
3.4, to accrued and unpaid interest (including at the Default Interest Rate to
the extent applicable) and then to principal due on the Notes.

         3.10. Conditional Conversion Right. In the event that the Company shall
extend the maturity date of the Loans pursuant to Section 3.2(b), above, or in
the event that on the six month anniversary date of the Closing Date the Company
shall fail to pay all Indebtedness owing under this Agreement and the Notes,
then, subject to the terms of this Section 3.10, each Holder of a Note shall
have right (the "Conditional Conversion Right") to convert the then-outstanding
principal amount of the Note held by it and the accrued and unpaid interest
thereon (in whole or in part) into convertible subordinated debentures of the
Company (the "Series B-1 Debentures") ranking pari passu with the Company's
Series B 9.75% Convertible Pay-In-Kind Debentures due 2007 (the "Series B
Debentures"), which Series B-1 Debentures shall be issued pursuant to the
Indenture (as hereinafter defined).

                  (a) Mechanics of Conversion. A Holder shall effect conversions
         hereunder by delivering to the Company by facsimile to the attention of
         the Company's Chief Financial




                                       8
   9

         Officer at (414) 918-5055 a completed conversion notice in the form
         attached as Exhibit A to the Notes (a "Conversion Notice") and delivery
         to the Company within two business days thereafter of the Note to be
         converted in whole or in part. Each Conversion Notice shall specify the
         date on which such conversion is to be effected, which date may not be
         prior to the date such Conversion Notice is delivered hereunder (a
         "Conversion Date") If no Conversion Date is specified in a Conversion
         Notice, then the Conversion Date shall be the date that such Conversion
         Notice is delivered hereunder. Each Conversion Notice, once given,
         shall be irrevocable. If a Holder is converting less than all of the
         principal amount represented by the Note tendered by such Holder with
         the Conversion Notice, or if a conversion hereunder cannot be effected
         in full for any reason, then the Company shall honor such conversion to
         the extent permissible hereunder and shall promptly deliver to such
         Holder a replacement Note in the same tenor for such principal amount
         as has not been converted.

                  (b) Issuance of Series B-1 Debentures. The Company shall take
         all actions necessary to permit the issuance of the Series B-1
         Debentures upon any conversion that would be permitted by Section
         3.10(a) above, including, without limitation, any action necessary to
         amend the Original Indenture so as to permit the issuance of Series B-1
         Debentures upon the exercise of the Conditional Conversion Right for
         all of the Notes pursuant to this Agreement. Each Lender in its
         capacity as a holder of PIK Debentures agrees to consent (or to cause
         any subsequent holder of such PIK Debentures to consent) to the such
         amendment to the Original Indenture and to the issuance of the Series
         B-1 Debentures (including, without limitation, consenting to the Series
         B-1 Debentures as "Permitted Indebtedness" under the Original Indenture
         and consenting to a supplemental indenture to the Original Indenture in
         order to permit the issuance of the Series B-1 Debentures thereunder in
         accordance with Section 11.2 of the Original Indenture).

                  (c) Terms of Series B-1 Debentures. The Series B-1 Debentures
         shall be identical to, and rank pari passu with, the Series B
         Debentures except that (i) the Series B-1 Debentures shall be
         convertible into Series B-1 Stock; and (ii) the Conversion Price (as
         that term is used in the Indenture) of the Series B-1 Debentures shall
         be equal to the greater of (1) $75 per share of Series B-1 Stock and
         (2) (x) the lowest price per share (or the lowest conversion price of
         any convertible security) of any shares of the Company's Series B
         Non-Voting Participating Preferred Stock (the "Series B Stock") or
         Series B-1 Stock (or other securities convertible into such Series B
         Stock or Series B-1 Stock) sold by the Company during the first six (6)
         months following the Closing Date or (y) 100 times the lowest price per
         share of shares of the Company's common stock, $.01 par value per share
         (the "Common Stock") (or the lowest conversion price of any other
         securities convertible into Common Stock) sold by the Company during
         the first six (6) months following the Closing Date; provided, however,
         that clauses (x) and (y) above shall not apply to any sale of
         securities unless the aggregate gross proceeds of such sale equals or
         exceeds $5,000,000.

                  (f) The Company shall not be in default with respect to any of

                                    ARTICLE V
                         Representations and Warranties

         5.1. Representations and Warranties of the Company. In order to induce
the Lenders to enter into this Agreement, the Company represents and warrants to
the Lenders, which representations and warranties shall survive the Closing and
be independent of any investigation or lack of investigation of Company made by
or on behalf of Lenders, as follows:

                  (a) Organization and Standing; Authorization of Series B-1
         Stock. The Company is duly incorporated and validly existing under the
         laws of the State of Delaware, and has all requisite corporate power
         and authority to own or lease its properties and assets and to conduct
         its business as it has been and is proposed to be conducted. The
         Company is qualified to do business and in good standing in each
         jurisdiction in which the failure to so qualify could have a material
         adverse effect upon its assets, properties, liabilities, financial
         condition, results of operations or business. The Company is duly
         authorized to issue up to 300,000 shares of Series B-1 Stock in
         accordance with the form of "Certificate of Designations, Rights and
         Preferences of the Series B-1 Non-Voting Participating Preferred Stock"
         previously furnished to the Lenders, which certificate has been duly
         adopted by the Company's board of directors and duly filed by the
         Company pursuant Section 151 of the General Corporation Law of the
         State of Delaware.

                  (b) Capacity of the Company; Consents; Execution of
         Agreements. The Company has the requisite power, authority, and
         capacity to enter into this Agreement, the Notes, the Warrants, and the
         agreements contemplated hereby and to perform the transactions and
         obligations to be performed by the Company hereunder and thereunder.
         Except as described on Schedule 5.1(b) hereto, no consent,
         authorization, approval,



                                       11
   12

         license, permit or order of, or filing with, any Person or
         Governmental Authority is required in connection with the execution
         and delivery of this Agreement, the Warrants and agreements
         contemplated thereby, or the performance by the Company of the
         transactions and obligations to be performed by it hereunder and
         thereunder, except as contemplated by said agreements. The failure to
         obtain any of the consents described on Schedule 5.1(b) prior to the
         Closing Date will not have a material adverse effect upon the
         Company's assets, properties, liabilities, financial condition,
         results of operations or business. The execution and delivery of this
         Agreement, the Notes, the Warrants and agreements contemplated thereby
         by the Company, and the performance of the transactions and
         obligations contemplated hereby and thereby by the Company have been
         duly authorized by all requisite action of the Company. This Agreement
         has been, and the Warrants and agreements contemplated hereby will be,
         duly executed and delivered by a duly authorized officer of the
         Company and constitutes, or when executed and delivered will
         constitute, a valid and legally binding agreement of the Company,
         enforceable in accordance with its terms, except as enforcement
         thereof may be limited by bankruptcy, insolvency, reorganization,
         moratorium or other similar laws, both state and federal, affecting
         the enforcement of creditors' rights or remedies in general from time
         to time in effect and the exercise by courts of equity powers or their
         application of principles of public policy.

                  (c) Valid Issuance. The Notes and the Warrants to be issued
         hereunder, when issued by the Company to the Lenders pursuant to the
         terms of this Agreement, will be duly authorized and validly issued.

                  (d) Conflicts; Defaults. The execution and delivery of this
         Agreement, the Notes, the Warrants and agreements contemplated hereby
         by the Company, and the performance by the Company of the transactions
         and obligations contemplated hereby and thereby to be performed will
         not (i) violate, conflict with, or constitute a default under any of
         the terms or provisions of its certificate of incorporation or bylaws,
         or any provisions of, or result in the acceleration of any obligation
         under, any Contract, note, debt instrument, security agreement, or
         other instrument to which the Company, or any Subsidiary is a party or
         by which the Company, or any Subsidiary or any of their respective
         assets is bound; (ii) result in the creation or imposition of any Liens
         or claims upon the assets of the Company, or any Subsidiary or their
         issued and outstanding capital stock; (iii) constitute a violation of
         any law, statute, judgment, decree, order, rule, or regulation of a
         Governmental Authority applicable to the Company, or any Subsidiary; or
         (iv) constitute an event which, after notice or lapse of time or both,
         would result in any of the foregoing. The Company is not presently in
         violation of any provision of its certificate of incorporation or
         bylaws. Neither the Company nor any Subsidiary is presently in default
         in any material respect under any of the terms or provisions of any of
         its material Contracts, notes, debt instruments, security agreements,
         or other instruments, or any order, judgment, or decree relating to it
         or its business or by which it or any of its assets is bound except
         with respect to the matters set forth on Schedule 5.1 (e).



                                       12
   13

                  (e) Periodic Reports. The Company has timely filed with the
         SEC all periodic reports heretofore required to be filed by it pursuant
         to the 1934 Act and all such periodic reports (including the financial
         statements or information forming a part thereof) are complete and
         comply, in all material respects, with the requirements of the SEC
         applicable to such periodic reports and financial statements.

                  (f) Compliance with Laws. The Company is not in violation of,
         nor do any of its operations violate in any respect, any statute, law,
         or regulation of any Governmental Authority applicable to the Company,
         any of its assets, or the conduct of its business ("Applicable Laws"),
         the violation of which reasonably could be anticipated to have a
         material adverse effect upon the Company's assets, properties,
         liabilities, financial condition, results of operations or business,
         and no material expenditures are or, based on present requirements,
         will be required of the Company in order for it to comply or remain in
         compliance with any Applicable Laws.

                  (g) Litigation. The Company is not a party to any material
         legal action, suit, claim, investigation or proceeding which is not
         adequately described in a periodic report heretofore filed by the
         Company with the SEC except for the matters described on Schedule 5.1
         (h), which will be disclosed by the Company in its next filing with the
         SEC, and, to the best of the Company's knowledge and belief after due
         inquiry, there exist no facts or circumstances which reasonably could
         be anticipated to result in any such action, suit, claim,
         investigation, or proceeding.

                  (h) Taxes. The Company has prepared and duly and timely filed
         with each appropriate Governmental Authority, all material federal,
         state, municipal, local and foreign tax returns, information returns
         and other reports required to be filed on or before the date of this
         Agreement and has paid all material taxes required to be paid by the
         Company prior to the date of this Agreement in respect of the periods
         covered by such returns and reports, except such taxes as are being
         contested in good faith.

                  (i) Environmental Compliance. The Company and its Subsidiaries
         are in compliance with all applicable federal, state and local laws and
         requirements (including permit requirements) relating to the protection
         of health or the environment in connection with the ownership,
         operation and condition of its properties and business, except where
         failure to comply would not have material adverse effect.

                  (j) Securities Laws. No consent, authorization, approval,
         permit, or order of or filing with any Governmental Authority is
         required in order for the Company to execute and deliver this Agreement
         or to offer, issue, sell, or deliver the Notes and the Warrants. Based
         in part on the representations of the Lenders and under the
         circumstances contemplated hereby and under current laws and
         regulations, the offer, issuance, sale and delivery of the Notes and
         the Warrants to the Lenders are exempt from the prospectus delivery and
         registration requirements of the 1933 Act.


                                       13
   14

                  (k) Hedging Obligations. Company and its Subsidiaries do not
         have any outstanding Hedging Obligations except to the extent entered
         into pursuant to and in compliance with any credit agreements to which
         they may be a party.

                  (l) Disclosure. The Company has fully responded to all written
         requests for information and has accurately answered, to the best of
         the Company's knowledge and belief after due inquiry, all written
         questions from the Lenders concerning the assets, properties,
         liabilities, financial condition, results of operations, business and
         prospects of the Company, and has not knowingly withheld any facts
         relating thereto which it reasonably believed to be material with
         respect to the assets, properties, liabilities, financial condition,
         results of operations, business or prospects of the Company. No
         information in this Agreement, or in any Schedule or Exhibit attached
         to this Agreement or delivered to the Lenders in connection herewith,
         contains any untrue statement of a material fact or when considered
         together with all such information delivered to any Lender omits to
         state any material fact necessary in order to make the statements made
         in the light of the circumstances under which they were made, when
         taken as a whole, not misleading. The disclosures made in writing by
         the Company in connection with this Agreement do not contain any untrue
         statement of a material fact nor omit to state a material fact
         necessary to make the statements made therein not misleading. There is
         no fact or circumstance relating to the Company which materially and
         adversely affects or in the future may, in the reasonable business
         judgment of the Company, be expected materially and adversely to affect
         the same which has not been set forth in this Agreement or the
         Schedules hereto.

                 (m) Contracts. Except for this Agreement and the agreements
         contemplated hereby and thereby, the Company has filed all material
         contracts required to be filed by Item 601(b)(10) of Regulation S-K
         under the 1933 Act and the 1934 Act as of September 30, 2000.

                 (n) Schedule of Certain Payables. Company has furnished to
         Lenders a schedule, which Borrower warrants and represents is true and
         accurate in all material respects, which sets forth an aged accounts
         payable schedule showing all amounts owing to Persons which have
         furnished labor, material or services with respect to improvement of
         the Collateral Real Estate or are otherwise owed amounts with respect
         to which such Person has, or upon compliance with applicable law has
         the right to obtain, a Lien on any of the Collateral Real Estate.

         5.2      Representations and Warranties of the Lenders. Each Lender
(solely as to itself and not as to any other Lender) represents and warrants to
the Company that:

                  (a) Investment Intent. The Note to be issued to such Lender is
         being acquired for its own account and not with the view to, or for
         resale in connection with, any distribution or public offering thereof
         within the meaning of the 1933 Act. Such Lender understands that such
         Note has not been registered under the 1933 Act by reason of its
         issuance in a transaction exempt from the registration and prospectus
         delivery



                                       14
   15

         requirements of the 1933 Act pursuant to Section 4(2) thereof. It
         further understands that such Note will bear the following legend and
         agrees that it will hold such Note subject thereto:

                  THIS NOTE HAS NOT BEEN REGISTERED PURSUANT TO THE SECURITIES
                  ACT OF 1933 OR ANY STATE SECURITIES LAW. NEITHER THIS NOTE NOR
                  ANY PORTION HEREOF OR INTEREST HEREIN MAY BE SOLD, ASSIGNED,
                  TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF UNLESS THE SAME
                  IS REGISTERED UNDER SAID ACT AND ANY APPLICABLE STATE
                  SECURITIES LAW, OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION
                  IS AVAILABLE AND THE COMPANY SHALL HAVE RECEIVED, AT THE
                  EXPENSE OF THE HOLDER HEREOF, EVIDENCE OF SUCH EXEMPTION
                  REASONABLY SATISFACTORY TO THE COMPANY (WHICH MAY INCLUDE,
                  AMONG OTHER THINGS, AN OPINION OF COUNSEL SATISFACTORY TO THE
                  COMPANY).

                  (b) Capacity of the Lender; Execution of Agreement. Such
         Lender has all requisite power, authority, and capacity to enter into
         this Agreement, and to perform the transactions and obligations to be
         performed by it hereunder. This Agreement has been duly authorized,
         executed and delivered by it and constitutes its valid and legally
         binding obligation, enforceable in accordance with its terms, except as
         enforcement thereof may be limited by bankruptcy, insolvency,
         reorganization, moratorium or other similar laws, both state and
         federal, affecting the enforcement of creditors' rights or remedies in
         general from time to time in effect and the exercise by courts of
         equity powers or their application of principles of public policy.

                  (c) Accredited Investor. Such Lender and, if such Lender is a
         limited partnership or limited liability company, each partner or
         member of such Lender is an "accredited investor" as defined in Rule
         501 (a) of Regulation D promulgated under the 1933 Act.

                                   ARTICLE VI
                            Covenants and Agreements

         6.1.     Affirmative Covenants. So long as any Indebtedness remains
outstanding under this Agreement and the Notes, the Company covenants and agrees
that it will and will cause each Subsidiary to:

                  (a)      Certain Information and SEC Reports. Furnish to each
         Lender in form and substance satisfactory to such Lender:

                           (i) within five (5) days after the Company learns of
                  the commencement or overtly threatened commencement of any
                  material claim or


                                       15
   16

                  suit, legal or equitable, or of any administrative,
                  arbitration, or other similar proceeding against the Company
                  or any of its Subsidiaries, or any of their respective
                  businesses, assets, or properties which claim or proceeding,
                  if determined adversely to the Company or such Subsidiary,
                  would be likely to have a material adverse effect on the
                  Company and its Subsidiaries, taken as a whole, written
                  notice of the nature and extent of such suit or proceeding;

                           (ii) within five (5) days after the Company learns of
                  any circumstance or event which reasonably can be expected to
                  have a material adverse effect on the assets, properties,
                  liabilities, financial condition, results of operations,
                  business, or prospects of the Company, written notice of the
                  nature and extent of such circumstance or event;

                           (iii) simultaneous with the transmission thereof to
                  Company's shareholders, copies of (or notice from an EDGAR
                  watch service of) all financial statements, proxy statements,
                  reports and any other general written communications which the
                  Company sends to its shareholders and copies (or notice from
                  an EDGAR watch service of) of all registration statements and
                  all regular, special or periodic reports which it files with
                  the SEC or with any securities exchange on which any of its
                  securities are then listed, and copies of all press releases
                  and other statements made available generally by the Company
                  to the public concerning material developments in the
                  Company's businesses; and

                           (vii) within ten (10) days after any Holder makes a
                  reasonable request therefor, such other data relating to the
                  business, affairs and financial condition of the Company or
                  any of its Subsidiaries.

                  (b) Taxes. Pay and discharge all taxes and other governmental
         charges before the same shall become overdue, unless and to the extent
         only that such payment is being contested in good faith.

                  (c) Insurance. Maintain insurance coverage on its physical
         assets and against other business risks in such amounts and of such
         types as are customarily carried by companies similar in size and
         nature, and in the event of acquisition of additional property, real or
         personal, or of incurrence of additional risks of any nature, increase
         such insurance coverage in such manner and to such extent as prudent
         business judgment and present practice would dictate.

                  (d) Examination of Books. Permit each Lender, through its
         authorized attorneys, accountants and representatives, to examine the
         Company's books, accounts, records, ledgers and assets of every kind
         and description at all reasonable times upon oral or written request of
         the Lender, at the Company's cost and expense (provided that so long as
         the Company shall not be in default, the Company shall be obligated to
         pay for no more than one (1) such examination per year).




                                       16
   17

                  (e) Notification of Events of Default, Acceleration or
         Material Adverse Effect. Promptly notify each Lender of any condition
         or event which constitutes, or with the passage of time and/or the
         giving of notice would constitute, an Event of Default under this
         Agreement or of payment defaults aggregating more than $10 million on
         any Indebtedness of the Company and its Subsidiaries or of any
         acceleration of the maturity of any Indebtedness of the Company and its
         Subsidiaries aggregating more than $10 million, and promptly inform
         each Lender of the existence or occurrence of any condition or event
         (other than conditions having an effect on the economy in general)
         which could reasonably be anticipated to have a material adverse effect
         upon the Company's financial condition.

                  (f) Maintenance of Licenses. Maintain in good standing all
         licenses required by any Governmental Authority that may be necessary
         or required for the Company and its Subsidiaries to carry on their
         respective businesses, where the failure to maintain such licenses
         would have a material adverse effect on the Company and its
         Subsidiaries taken as a whole.

                  (g) ERISA Compliance. Comply with all material requirements
         imposed by ERISA as presently in effect or hereafter promulgated,
         including but not limited to, the minimum funding requirements of any
         defined contribution employee benefit plan ("Pension Plan").

                  (h) Compliance with Law. Comply in all material respects with
         all applicable laws, rules, regulations and orders of any Governmental
         Authority, such compliance to include, without limitation, paying
         before the same become delinquent all taxes, assessments, and
         governmental charges imposed upon it or upon its property, including
         without limitation the Collateral Real Estate, except to the extent
         that compliance with any of the foregoing is then being contested in
         good faith by appropriate legal proceedings and with respect to which
         adequate financial reserves have been established on the books and
         records of the Company and except where the failure to comply would not
         have a material adverse effect on the Company and its Subsidiaries,
         taken as a whole.

                  (i) Right of Co-Investment. Prior to issuing any Equity
         Security, as hereinafter defined (otherwise than upon the exercise of
         the Warrants or currently outstanding stock options or upon the
         conversion or payment of pay-in-kind dividends or interest on currently
         outstanding convertible debentures and preferred stock), at any time
         prior to the Notes being repaid in full or converted pursuant to
         exercise of the Conditional Conversion Right (an "Alterra Equity
         Transaction"), the Company shall afford each Holder the opportunity, on
         not less than ten (10) days prior written notice, to co-invest in the
         Alterra Equity Transaction by converting the outstanding Indebtedness
         to such Holder under this Agreement and the Note held by it into a
         participation in such Alterra Equity Transaction on the same terms
         afforded to other participants in such Alterra Equity Investment;
         provided, however, that (i) such co-investment right must be exercised
         by each Holder at the time of execution of the definitive purchase
         agreement for the Alterra Equity Transaction, and (ii) as a minority
         participant in such Alterra Equity Transaction,



                                       17
   18

         the Holders acknowledge that their control and voting rights may be
         substantially limited (in the manner required by the principal
         investor in such Alterra Equity Investment). In the event that the
         Equity Securities to which the Holders rights extend under the
         provisions hereof consist of Securities having the right to vote on
         the election of directors or granting to the Holder the right to
         obtain Securities having the right to vote on the election of
         directors, each Holder may require that, with respect to such Holder,
         the Alterra Equity Transaction only consist of Securities which do not
         contain such right to vote or to obtain Securities having such right
         to vote but otherwise providing to such Holder substantially the same
         economic benefits as it would have obtained if it had received
         Securities having such right to vote or was granted the right to
         obtain Securities having such right to vote, and which are convertible
         into such Securities having the right to so vote on a share-for-share
         or equivalent basis at such time(s) or upon the happening of such
         event(s) as such Holder may reasonably request.

                  "Equity Security" shall mean any equity security of the
         Company or Subsidiary (except for any securities issued by any
         Subsidiary to the Company or to any Subsidiary that is 100% owned by
         the Company), including, without limitation, common or preferred stock,
         any profit sharing or similar arrangement giving any Person a right or
         interest in the profits of the Company or any Subsidiary or in any
         property owned by any one or more of them, any debt security of the
         Company convertible, directly or indirectly, into an equity security of
         the Company or any Subsidiary or into any such profit sharing or
         similar arrangement, or any option, warrant or right to acquire,
         directly or indirectly, any of the foregoing.

                  (j) Title Insurance. On the Closing Date, the Company shall
         purchase mortgagee title insurance for the Lenders pursuant to the
         Title Commitments.

                  (k) Rights Plan. Not less than 90 days after the Closing Date,
         the Company shall take such action as reasonably required by the
         Lenders funding not less that $5 million of the aggregate Loan
         Commitment (including seeking the consent of Bank of America N.A., to
         the extern required) so that: (i) the holders of the Series B-1 Stock
         will have rights to acquire additional shares of Series B-1 Stock which
         are substantially similar and proportionate to the rights distributed
         to holders of Common Stock pursuant to the Rights Plan; and (ii) the
         holders of Series B-1 Debentures will receive upon conversion of such
         Series B-1 Debentures into Series B-1 Stock, respectively, rights or
         additional shares, as the case may be, as necessary so that the
         proportionate interests in the Company which they would have been
         entitled to receive upon such conversion, but for the effect of the
         distribution or exercise of rights distributed pursuant to the Rights
         Plan or the immediately preceding clause (i), will not have been, or
         thereafter be, diminished as a result of the distribution or exercise
         of such rights granted to holders of the Company's Common Stock, Series
         A 9.75% Cumulative Convertible Pay-In-Kind Preferred Stock or Series B
         Stock. The "Rights Plan" means that certain plan implemented pursuant
         to the Rights Agreement between the Company and American



                                       18
   19

         Stock Transfer & Trust Company, as rights agent, dated as of December
         10, 1998, as the same may be amended.

         6.2.     Negative Covenants. The Company covenants and agrees that so
long as any Indebtedness remains outstanding under this Agreement and the Notes,
without the prior written consent of Holders holding not less than 80% in
outstanding principal amount of the Notes, Company will not:

                  (a) No Mergers, Etc. Enter into any merger or consolidation or
         sell, lease, transfer or dispose of all, substantially all, or any
         material part of its assets, except in the ordinary course of its
         business and except for sales of assets approved by the Board of
         Directors of the Company in accordance with the provisions of the
         Company's bylaws.

                  (b) Limitations on Indebtedness. Become or remain obligated,
         or suffer or permit any Subsidiary to become or remain obligated, for
         any Indebtedness, except:

                           (i) Indebtedness arising pursuant to this Agreement;
                  and

                           (ii) other Indebtedness, whether now outstanding or
                  hereafter incurred, provided that the sum of all of the
                  Indebtedness of the Company and the Subsidiaries at any time
                  outstanding on a consolidated basis (excluding, however, any
                  Indebtedness arising as a result of acquisitions or business
                  combinations effected after the date of this Agreement) does
                  not exceed $1,850,000,000.00 plus the outstanding Indebtedness
                  with respect to the PIK Debentures.

                  (c) Limitations on Mortgages. Create or permit to exist any
         Lien on the Collateral Real Estate, other than Permitted Liens and
         mortgages in favor of Lender.

         6.3.     Reservation of Shares. The Company shall at all times have
reserved for issuance a sufficient number of shares of Series B-1 Stock to
permit the exercise in full of all Warrants and the conversion of any of the
Series B-1 Debentures as may be issued pursuant to the Conditional Conversion
Right of all of the Holders.

                                   ARTICLE VII
                                  Miscellaneous

         7.1.     Waiver and Amendments. No failure or delay on the part of a
Lender in the exercise of any power or right, and no course of dealing between
Company and such Lender, shall operate as a waiver of such power or right, nor
shall any single or partial exercise of any power or right preclude other or
further exercise thereof or the exercise of any other power or right. Remedies
provided for herein are cumulative and not exclusive of any remedies which may
be available to the Lenders at law or in equity. No notice to or demand on the
Company required hereunder or under the Notes shall in any event entitle Company
to any other or further notice or demand in similar or other circumstances or
constitute a waiver of the right of any Lender to any other or further action
and any circumstances without notice or demand. Except as may otherwise be
specifically provided



                                       19
   20

in this Agreement, no amendment, modification or waiver of, or consent with
respect to, any provision of this Agreement or the Notes shall in any event be
effective with respect to any Lender unless the same shall be in writing and
signed and delivered by such Lender. Any waiver of any provision of this
Agreement or the Notes, and any consent to any departure by Company from the
terms of any provision of this Agreement or the Notes, shall be effective only
in the specific instance and for the specific purpose for which given. The
Company shall not enter into any amendment of this Agreement or of any Note with
any Holder, unless the Company shall have offered in writing to each other
Holder on not less than five (5) days notice to enter into an amendment with
each other Holder on the same terms and conditions.

         7.2. Notices. All notices and other communications required or

Business Days after the post-mark date thereof. Notices may be given by

         7.3. Restriction on Transfer. The Lenders acknowledge that the Notes
have not been registered under the Securities Act of 1933, as amended, (the
"1933 Act") or the securities laws of any state. Accordingly, the Notes may not
be sold or otherwise disposed of or transferred, unless such sale, disposition
or transfer is registered under the 1933 Act and applicable state securities
laws or unless the Company has received an opinion of counsel reasonably
acceptable to the Company that such sale, disposition or transfer is exempt from
such registration. The Notes shall bear a restrictive legend to the foregoing
effect.

         7.4. Expenses. Company shall reimburse the Lenders for all of its
