Original Note and, in substitution therefor, the Company delivered to Lender the

of this Agreement, the Company shall deliver an amended and restated promissory
note in the form of Exhibit F attached hereto (the "$34 Million Note") to extend

ALS-WovenHearts, Inc. shall guaranty the Loans upon and subject to the terms and
conditions hereinafter set forth. The funds disbursed at the Second Disbursement
shall be disbursed directly to or paid for the benefit of the Company and in

Additional Collateral Real Estate (as described on Exhibit B as "To Be

its absolute discretion. This is not a revolving credit agreement and any part

Closing Date from the proceeds of the $25 Million Loan. On the third (3rd) day
of each month, starting with May 3, 2000, Company shall pay to Lender facility
fees equal to Thirteen Thousand Three Hundred Thirty Three and No/100 Dollars
($13,333.00), multiplied by a fraction, the numerator of which is the amount by
which the outstanding principal amount of the $34 Million Note at such date
exceeds Fourteen Million Dollars ($14,000,000.00) and the denominator of which
is One Million Dollars ($1,000,000.00). None of such facility fees shall be
prorated in the event of prepayment of the Notes. If any facility fee is not
paid when due, interest shall accrue thereon at the Default Interest Rate, as

                                 ARTICLE III
                       Terms of the Loans and the Notes
                       --------------------------------

      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 February 4, 2000 to, but not including, the date
      on which all outstanding principal and accrued and unpaid interest and
      fees on the Loans have been paid in full, principal amount of the Loans
      outstanding from time to time shall bear interest at the rate of ten
      percent (10%) per annum. During any period that an Event of Default shall
      have occurred and be continuing, interest on principal amount of the Loans
      outstanding from time to time shall accrue at a rate equal to fifteen
      percent per annum (15%) (the "Default Interest Rate"). Notwithstanding
      anything contained herein to the contrary, in no event shall the interest
      rate on the Loans, including the Default Interest Rate, exceed the highest
      rate permitted by applicable law. Interest on the Loans, including
      interest at the Default Interest 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 on the principal amount outstanding from time to
      time shall be payable monthly in arrears beginning on April 30, 2000 and
      on the last day of each month thereafter until the principal and all
      accrued interest and facility fees have been paid in full.

            (b) It is the intention of the Company and Lender 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 the
      Holder, either be rebated to the Company or credited on the principal
      amount of the Loans; 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







                                       6
<PAGE>   7
      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 Holder 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 Loans 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) $34 MILLION NOTE. Unless the same shall become due earlier as a
      result of acceleration of the maturity, the $34 Million Note shall mature

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

            (a) 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, including interest on any delinquent
      facility fees, then to the payment of any facility fees that are due and
      payable and then to principal.

      such First Additional Collateral Real Estate to be released and marked
      satisfied of record. No such partial release shall limit or impair the
      right of Lender in any other collateral pledged hereunder.

      Million Note, provided no Default or Event of Default is then outstanding,

      3.6.  Acceleration.
            -------------

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

            (b) Rescission. At any time after a declaration of acceleration with
      respect to the Loans, the Holder may, in its sole discretion, rescind and
      cancel such declaration and


                                       10
<PAGE>   11
      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, the
Holder may pursue any available remedy to collect the payment of principal and
interest (including interest at the Default Interest Rate) on the Loans and to
enforce the performance of any provision of the Notes or this Agreement and any
other agreement related to any Loan. A delay or omission by the 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. The 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 the Holder hereunder and under the
Notes shall be applied first to all costs and expenses of collection, including
reasonable attorneys' fees, then to accrued and unpaid interest (including at
the Default Interest Rate to the extent applicable), then to facility fees, and
then to principal.

                        Representations and Warranties
                        ------------------------------


      5.1. Representations and Warranties of the Company. In order to induce the
Lender to enter into this Agreement, the Company represents and warrants to the
Lender, 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 Lender, as follows with such representations and warranties to be
effective as to the Company and WovenHearts and Holding as of the date of this
Agreement and with such representations and warranties as to the LLCs to be
effective as of the Initial Disbursement Date:

            (a) Organization and Standing; Issued and Outstanding Shares. Each
      of the Company, the LLCs, ALS-WovenHearts, Inc. ("WovenHearts") and
      Holding is duly incorporated or formed, as the case may be, and validly
      existing under the laws of the State of Delaware, and has all requisite
      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. Each
      of the Company, the LLCs, WovenHearts and Holding 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. Holding has no Subsidiaries other than AHC Purchaser, Inc., all
      of the issued and outstanding shares of which are owned by Holding. The
      Certificate of Incorporation or Operating Agreement, as applicable, and
      amendments thereto of each of Holding, WovenHearts, the LLCs and AHC
      Purchaser, Inc., are in the form previously provided to Lender. The issued
      and outstanding capital stock of Holding is as set forth in Schedule
      5.1(a). As of the Initial Disbursement Date, the Company will own 100% of
      the membership interests and be the sole member of each of the LLCs. The
      Company owns 100% of the shares of capital stock of WovenHearts.

            (b) Indebtedness and Contracts of Holding and LLCs. Except for such
      Contracts or Indebtedness as are contemplated hereby or thereby as set
      forth on Schedule 5.1(b), the LLCs and Holding have no Indebtedness and
      are not a party to any Contracts (whether formal or informal, written or
      oral, firm or contingent), other than (i) the pledge by Holding of the
      capital stock of AHC Purchaser, Inc., delivered in connection with the
      recent financing provided by GMAC, and (ii) those Contracts to be assigned
      by the LLCs to Lender as provided in Section 4.1(c)(v) of this Agreement
      on the Initial Disbursement Date.

            (c) Capacity of the Company; Consents; Execution of Agreements. The
      Company has the requisite power, authority, and capacity to enter into
      this Agreement and the agreements contemplated hereby and to perform the
      transactions and obligations to be performed by the Company hereunder and
      thereunder. Holding, WovenHearts and the LLCs have the requisite power,
      authority and capacity to enter into the agreements contemplated hereby,
      as applicable, and to perform the transaction and obligations to be


                                       14
<PAGE>   15
      performed by Holding, WovenHearts and the LLCs thereunder, as applicable.
      Except as described on Schedule 5.1(c) hereto, no consent, authorization,
      approval, 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 or the performance by the Company, Holding, the
      LLCs, or WovenHearts of the transactions and obligations to be performed
      by it hereunder, except as contemplated by this Agreement. The failure to
      obtain any of the consents described on Schedule 5.1(c) prior to the $25
      Million Note 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 and
      the performance of the transactions and obligations contemplated hereby by
      the Company have been (or, with respect to the LLCs will be) duly
      authorized by all requisite action of the Company, the LLCs, WovenHearts
      and Holding, as applicable. This Agreement has been 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.

            (d) Status of Notes. The Notes to be issued hereunder, when issued
      by the Company to the Lender pursuant to the terms of this Agreement, will
      be duly authorized and validly issued.

            (e) Conflicts; Defaults. The execution and delivery of this
      Agreement and the execution by the LLCs, Holding and WovenHearts of a
      guaranty of the Loans and the pledge by Company of the membership
      interests of the LLCs and the shares of Holding to secure the Company's
      obligations hereunder and under the Notes, and the performance by the
      Company, the LLCs, WovenHearts and Holding of the transactions and
      obligations contemplated hereby and thereby to be performed by each 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 its
      Operating Agreement, as applicable, 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, the LLCs,
      Holding, WovenHearts or any other Subsidiary is a party or by which the
      Company, the LLCs, Holding, WovenHearts or any other Subsidiary or any of
      their respective assets is bound, except for such conflicts, violations,
      breaches or defaults which would not have, or reasonably be expected to
      have, a Material Adverse Effect; (ii) result in the creation or imposition
      of any Liens or claims upon the assets of the Company, Holding,
      WovenHearts or any other Subsidiary or their issued and outstanding
      capital stock (except as contemplated by this Agreement); (iii) constitute
      a violation of any law, statute, judgment, decree, order, rule, or
      regulation of a Governmental Authority applicable to the Company, the
      LLCs, Holding, WovenHearts or any other Subsidiary; or (iv) constitute an
      event which, after notice or lapse of time or both, would result in any of



                                       15
<PAGE>   16
      the foregoing. None of the Company, the LLCs, Holding, WovenHearts or AHC
      Purchaser, Inc. is presently in violation of any provision of its
      certificate of incorporation or bylaws as to such corporations or its
      certificate of formation or operating agreement as to each LLC. None of
      the Company, the LLCs, Holding, WovenHearts or 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, except for the matters set forth on
      Schedule 3.1(j) of the Purchase Agreement and except for such defaults
      which would not have, or reasonably be expected to have a Material Adverse
      Effect, or any order, judgment, or decree relating to it or its business
      or by which it or any of its assets is bound.

            (f) 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.

            (g) Compliance with Laws. The Company, WovenHearts and the LLCs are
      not in violation of, nor do any of their operations violate in any
      respect, any statute, law, or regulation of any Governmental Authority
      applicable to the Company, any of their 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 or a
      Material Adverse Effect upon the LLCs' 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 or the LLCs in order for it to comply or remain in compliance
      with any Applicable Laws.

            (h) Litigation. Except as set forth in Schedule 3.1(ee) to the
      Purchase Agreement, 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 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. None of the LLCs are a party to any material legal action,
      suit, claim, investigation or proceeding which are not listed on Schedule
      3.1(ee) of the Purchase Agreement 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, other than the Permitted
      Liens.

            (i) 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

            (j) Environmental Compliance. The LLCs and 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.

            (k) 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 $25 Million Note. Based in part on the
      representations of the Lender and under the circumstances contemplated
      hereby and under current laws and regulations, the offer, issuance, sale
      and delivery of the Note to the Lender is exempt from the prospectus
      delivery and registration requirements of the 1933 Act.

            (l) Hedging Obligations. The LLCs and the 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.

            (m) 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 Lender 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 Lender in
      connection herewith, contains any untrue statement of a material fact or
      when considered together with all such information delivered to the 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.

            (n) Changes in Circumstances. Since December 31, 1999, and except as
      set forth or referenced in the Purchase Agreement, Company has not
      suffered any material adverse change in its assets, properties,
      liabilities, financial condition, results of operations, business or
      prospects.

            (o) Contracts. Except for this Agreement, the Purchase Agreement and
      the agreements contemplated hereby, 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.

            (p) Second Additional Collateral Real Estate. The amounts set forth
      (and the evidence provided in support) in Section 4.1(c)(i) and the
      amounts set forth on Exhibit D are true, correct and complete in all
      material respects.

      5.2 Representations and Warranties of the Lender. The Lender represents
and warrants to the Company that:

            (a) Investment Intent. The Notes are 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. The Lender understands that the Notes have not been registered under
      the 1933 Act by reason of its issuance in a transaction exempt from the
      registration and prospectus delivery requirements of the 1933 Act pursuant
      to Section 4(2) thereof. It further understands that the Notes will bear
      the following legend and agrees that it will hold the Notes 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. 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. The Lender and each member of Lender is an
      "accredited investor" as defined in Rule 501 (a) of Regulation D
      promulgated under the 1933 Act.

                           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 Lender in form
      and substance satisfactory to Lender:

                  (i) within five (5) days after the Company learns of the
            commencement or overtly threatened commencement of any material
            claim or 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 or, as to each LLC individually;

                  (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 and its Subsidiaries taken as a whole, or, as to each
            LLC individually, 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 the 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.





                                       19
<PAGE>   20
            (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 the 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).

            (e) Notification of Events of Default, Acceleration or Material
      Adverse Effect. Promptly notify the 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 any
      acceleration of the maturity of any Indebtedness aggregating $5 million or
      more of the Company, and promptly inform 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 (or, after the Second Disbursement Date, as to each LLC
      individually).

            (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




                                       20
<PAGE>   21
      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 (or, as to each LLC individually).

            (i)   [INTENTIONALLY DELETED]

            (j) Title Insurance. At the request of Lender, the Company shall
      purchase mortgagee title insurance for the Lender pursuant to the
      Additional Title Commitments furnished pursuant to this First Amended Loan
      Agreement and to the Title Commitments furnished pursuant to the Original
      Loan Agreement.

      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 Lender, 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.

            (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 the amount of Indebtedness
            set forth in the Financial Model dated on or about April 24, 2000
            delivered by the Company to Lender.

            (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.

                                Miscellaneous
                                -------------

      7.1. Waiver and Amendments. No failure or delay on the part of Lender in
the exercise of any power or right, and no course of dealing between Company and
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 Lender at law or in equity. No notice to or demand on the Company
required hereunder or under the Notes





                                       21
<PAGE>   22
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 Lender to
any other or further action and any circumstances without notice or demand. 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 unless the same
shall be in writing and signed and delivered by 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.

benefit of Company and Lender and their successors and assigns.

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

$34,000,000.00                                                Atlanta, Georgia
                                                                April 26, 2000

      WHEREAS, ALTERRA HEALTHCARE CORPORATION, a Delaware corporation (the
"Company") previously executed and delivered that certain Promissory Note dated
February 3, 2000, in the amount of $34,000,000.00 to Lender (the "Original
Note") with respect to a loan made pursuant to that certain Amended and Restated
Loan Agreement between Company and Lender of even date therewith;

      WHEREAS, the Company and Lender are entering into a Second Amended and
Restated Loan Agreement of even date herewith (the "Second Amended Loan
Agreement") whereby the parties have agreed, among other things, to amend the
maturity date of the Original Note; and

      WHEREAS, as a condition of the Second Amended Loan Agreement, the Company
has agreed to execute and deliver this Amended and Restated Promissory Note in
substitution for the Original Note and by acceptance hereof Lender agrees to
return the Original Note marked "cancelled" to the Company.

      IN CONSIDERATION OF THE FOREGOING, AND FOR VALUE RECEIVED, the Company
promises to pay to the order of RDVEPCO, L.L.C., a Michigan limited liability
company (the "Lender"), c/o RDV Corporation, 126 Ottawa Avenue, 500 Grand Bank
Building, Grand Rapids, Michigan 49503, Attn: President, or such other place as
designated in writing by the Holder, the principal sum of Thirty Four Million
and No/100 Dollars ($34,000,000.00) together with interest on the principal
balance outstanding from time to time in accordance with the provisions of this
Note. This Note has been executed and delivered pursuant to the Second Amended
Loan Agreement, the terms and conditions of which are incorporated herein by
reference.
<PAGE>   33
Unless otherwise indicated herein, capitalized terms used in this Note have the
same meanings set forth in the Second Amended Loan Agreement.

      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 Note, interest shall accrue
      under this Note from the date of the last payment under the Original Note
      through the date of this Note and continuing through the date on which all
      outstanding principal and accrued and unpaid interest on this Note have
      been paid in full. The principal amount outstanding from time to time
      under this Note shall bear interest at the rate of ten percent (10%) per
      annum. During any period that an Event of Default shall have occurred and
      be continuing, interest on this Note shall accrue at a rate equal to
      fifteen percent per annum (15%) (the "Default Interest Rate").
      Notwithstanding anything contained herein to the contrary, in no event
      shall the interest rate on this Note, including the Default Interest Rate,
      exceed the highest rate permitted by applicable law. Interest on this Note
      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
      monthly in arrears beginning on April 30, 2000 and on the last day of each
      month thereafter until the principal and all accrued interest on this Note
      have been paid in full.

            (b) It is the intention of the Company and Lender to conform
      strictly to applicable usury laws now or hereafter in force, and any
      interest payable under the Second Amended Loan Agreement or this Note
      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 the Holder, either be rebated to the Company or credited on the
      principal amount of this Note; or (iii) if this Note has 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 the Second
      Amended Loan Agreement and this Note 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 this Note
      (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 Holder so that the rate of interest on account
      of this Note, as so calculated is uniform throughout the term hereof. 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
      this Note is not limited by law, none of the provisions of this paragraph



                                       2
<PAGE>   34
      shall be construed so as to limit or reduce the interest or other
      consideration payable under the Second Amended Loan Agreement or this Note
      or under the instruments securing payment thereof. The terms and
      provisions of this paragraph shall control and supersede every other
      provision of all agreements between the Company and the Lender.

      2. Maturity. Unless the same shall become due earlier as a result of
acceleration of the maturity, this Note shall mature on the earlier of (i) the
Initial Closing (as such term is defined in the Purchase Agreement) of the
Alterra Equity Transaction, or (ii) the Initial Closing of a Financing Proposal
that is a Superior Proposal (as such terms are defined in the Purchase
Agreement), or (iii) February 2, 2001. Upon the earlier to occur of the
foregoing, the outstanding principal balance of this Note and all accrued and
unpaid interest shall become due and payable.

      3. Prepayments. The Company may from time to time prepay this Note, 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.

      4. Manner of Payment. The Company shall make payments in respect of this
Note (including principal and interest) by wire transfer of immediately
available funds to the account specified by the Holder.

      5. Events of Default; Acceleration. The maturity of this Note is subject
to acceleration if an Event of Default occurs and is continuing as set forth in
the Second Amended Loan Agreement.

      6. Collection Expenses. In the event Company fails to pay any installment
of interest or principal when due, Company shall pay to the Holder, in addition
to the amounts due, all costs of collection, including reasonable attorneys'
fees.

      7. Company Waivers. Company, for itself and its successors and assigns,
hereby waives demand, presentment, protest, diligence, notice of dishonor and
any other formality in connection with this Note and expressly agrees that this
Note, or any payment hereunder, may be extended from time to time and that the
Holder may accept security for this Note or release security for this Note, all
without in any way affecting the liability of Company hereunder.

      8. Governing Law. All questions concerning the construction, validity and
interpretation of this Note shall be governed by and construed in accordance
with the domestic laws of the State of Michigan, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of
Michigan or any other jurisdiction) that would cause the application of the laws
of any jurisdiction other than the State of Michigan.

      9. Amendment and Waiver. The provisions of this Note may be amended and
waived only with the prior written consent of the Company and the Holder.

      FOR VALUE RECEIVED, ALTERRA HEALTHCARE CORPORATION, a Delaware corporation
("Company"), promises to pay to the order of RDVEPCO, L.L.C., a Michigan limited
liability company (the "Lender"), c/o RDV Corporation, 126 Ottawa Avenue, 500
Grand Bank Building, Grand Rapids, Michigan 49503, Attn: President, or such
other place as designated in writing by the Holder, the principal sum of Twenty
Five Million and No/100 Dollars ($25,000,000.00) together with interest on the
principal balance outstanding from time to time in accordance with the
provisions of this Note. This Note has been executed and delivered pursuant to
that certain Second Amended and Restated Second Amended Loan Agreement between
the Company and the Lender dated of even date herewith (the "Second Amended Loan
Agreement"), the terms and conditions of which are incorporated herein by
reference. Unless otherwise indicated herein, capitalized terms used in this
Note have the same meanings set forth in the Second Amended Loan Agreement.

      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 Note, during the period
      commencing on the date of funding hereunder through, but not including,
      the date on which all outstanding principal and accrued and unpaid
      interest on this Note have been paid in full, the principal amount
<PAGE>   37
      outstanding from time to time under this Note shall bear interest at the
      rate of ten percent (10%) per annum. During any period that an Event of
      Default shall have occurred and be continuing, interest on this Note shall
      accrue at a rate equal to fifteen percent per annum (15%) (the "Default
      Interest Rate"). Notwithstanding anything contained herein to the
      contrary, in no event shall the interest rate on this Note, including the
      Default Interest Rate, exceed the highest rate permitted by applicable
      law. Interest on this Note 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 monthly in arrears beginning on April
      30, 2000 and on the last day of each month thereafter until the principal
      and all accrued interest on this Note have been paid in full.

            (b) It is the intention of the Company and Lender to conform
      strictly to applicable usury laws now or hereafter in force, and any
      interest payable under the Loan Agreement or this Note 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 the
      Holder, either be rebated to the Company or credited on the principal
      amount of this Note; or (iii) if this Note has 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 the Loan Agreement and this
      Note 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 this Note (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
      Holder so that the rate of interest on account of this Note, as so
      calculated is uniform throughout the term hereof. 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 this Note 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 the Second Amended Loan Agreement or this Note or under the
      instruments securing payment thereof. The terms and provisions of this
      paragraph shall control and supersede every other provision of all
      agreements between the Company and the Lender.

      2. Maturity. Unless the same shall become due earlier as a result of
acceleration of the maturity, this Note shall mature on the earlier of (i) the
Closing (as such term is defined in the Purchase Agreement) of an Alterra Equity
Transaction, or (ii) the Initial Closing of a Financing Proposal that is a
Superior Proposal (as such terms are defined in the Purchase Agreement), or
(iii) June 30, 2000. Upon the earlier to occur of the foregoing, the outstanding
principal balance of this Note and all accrued and unpaid interest shall become

Note (including principal and interest) by wire transfer of immediately
available funds to the account specified by the Holder.

to acceleration if an Event of Default occurs and is continuing as set forth in
the Second Amended Loan Agreement.

of interest or principal when due, Company shall pay to the Holder, in addition
to the amounts due, all costs of collection, including reasonable attorneys'
fees.

hereby waives demand, presentment, protest, diligence, notice of dishonor and
any other formality in connection with this Note and expressly agrees that this
Note, or any payment hereunder, may be extended from time to time and that the
