liability company ("Seller"), BLC Senior Holdings, Inc., a Delaware

                                  WITNESSETH

            WHEREAS, Seller, Indemnitor and Acquiror have entered into a Stock
Purchase Agreement dated as of the date hereof (the "Purchase Agreement"),
pursuant to which, among other things, Acquiror has agreed to acquire all the
outstanding shares of common stock of Brookdale Living Communities, Inc., a
Delaware corporation (the "Company");

            WHEREAS, upon the acquisition of all the outstanding shares of
common stock of the Company by Acquiror, the Company and each of its
wholly-owned corporate subsidiaries are intended to become qualified REIT
subsidiaries pursuant to Section 856(i) of the Code (defined below), the
Company and each of its wholly-owned direct and indirect corporate
subsidiaries will be deemed to liquidate under Section 332 of the Code for
Federal income tax purposes, and the tax year for the Company and various of
its subsidiaries will end on the Closing Date;

            WHEREAS, after being deemed liquidated under Section 332 of the

intended to be converted to limited liability companies that are not
classified as corporations for Federal income tax purposes;

            WHEREAS, after being converted to limited liability companies, all
the equity interests in the Company and each of its wholly-owned corporate
subsidiaries are intended to be contributed by the Acquiror to an entity that
is classified as a partnership for Federal income tax purposes in which the
Acquiror, directly or through one or more entities disregarded for Federal
income tax purposes, will be a partner; and

            WHEREAS, as a condition to entering into the Purchase Agreement
and the Transaction Agreements (as defined in the Purchase Agreement), and as
an inducement to do so, the parties hereto are entering into this Agreement;

            NOW, THEREFORE, in consideration of the promises and mutual

<PAGE>

      amendments thereto) including, combined or consolidated returns for any
      group of entities.

                  (n)   Any capitalized terms used herein and not defined
      herein, shall have the meaning assigned to it in the Purchase Agreement.

            Section 2.  Tax Liability for Straddle Period. For purposes of this
Agreement, the Tax liability of any entity with respect to a Straddle Period
shall be computed as follows: (i) in the case of Taxes of an entity that are
either based upon or related to income or receipts, the Tax liability for the
Straddle Period shall be deemed equal to the amount that would be payable if
the period for which such Tax is assessed had ended on and included the
Closing Date, not including transactions occurring on the Closing Date after
the Closing, determined, to the extent permissible under applicable laws and
commercially practicable, in a manner which is consistent with such entity's
accounting practices and business operations as in effect prior to the Closing
Date; (ii) in the case of Taxes that are incurred as a result of any sale,
transfer, assignment or distribution of property, or other similar transaction
engaged in, by any such entity, the Tax liability for the Straddle Period
shall be the amount due with respect to any such sale, transfer, assignment,
distribution, or other similar transaction occurring on or prior to the
Closing Date (not including transactions occurring on the Closing Date but
after the Closing); and (iii) in the case of all other Taxes, Tax liability
attributable to the Straddle Period shall be equal to the Taxes imposed with
respect to the Tax period that includes the Straddle Period multiplied by a
fraction, the numerator of which is the number of days in the Straddle Period
through and including the Closing Date and the denominator of which is the
number of days in the Tax period with respect to which such Taxes are imposed;
provided, however, that notwithstanding the foregoing provisions of this
section, with respect to real property Taxes, Section 2.04 of the Purchase
Agreement shall govern.

            Section 3.  Amount and Scope of Indemnification.

                  (a)   Indemnitor shall indemnify, defend, and hold harmless
      Acquiror against and reimburse Acquiror for all Taxes, losses, damages,
      cost, expenses, liabilities, obligations and claims of any kind
      (including reasonable attorneys' fees and costs of investigation) in
      connection with Taxes of the Company and the Company Subsidiaries that
      are attributable to a Pre-Closing Period, including without limitation
      Taxes properly allocable to a Straddle Period under Section 2, or that
      Acquiror may at any time suffer or incur, or become subject to, as a
      result of or in connection with the material inaccuracy of any
      representation or warranty made by Indemnitor in Section 3.19 (other
      than Section 3.19(l)) of the Purchase Agreement or in the schedules
      referred to in Section 3.19 of the Purchase Agreement. Acquiror, if and
      to the extent it qualifies as a REIT with respect to any taxable period
      and jurisdiction, shall not be required to make additional distributions
      to its shareholders to reduce or eliminate its liability for Taxes
      otherwise indemnified against hereunder, whether or not such
      distributions are required to be made to maintain the Acquiror's status
      as a REIT, but to the extent Acquiror is permitted to, and chooses to,
      make any such additional distributions to its shareholders, any
      reduction in Acquiror's liability for Taxes as a result of such
      additional distributions shall be taken into account in computing the
      Indemnity Amount hereunder.

                                       3
<PAGE>

                  (b)   In the event Acquiror makes a claim for
      indemnification hereunder, Acquiror shall provide Indemnitor with a
      written statement setting forth in reasonable detail the basis of the
      claim for indemnification and the calculation of the amount owing under
      Section 3(a) (the "Indemnity Amount").

                  (c)   Any payment determined due to Acquiror pursuant to
      this Section 3 shall be paid within the later of (i) twenty (20)
      business days after written notice from Acquiror to Indemnitor that such
      amounts are due and payable, or (ii) ten (10) business days prior to the
      due date for any return (including without limitation any return of
      estimated income taxes) on which Acquiror would reflect such income or
      gain.

                  (d)   Upon request of Indemnitor, the basis of the claim and
      the accuracy of Acquiror's calculation of the Indemnity Amount payable
      to Acquiror pursuant to Section 3 shall be verified by an independent,
      nationally recognized accounting firm (other than the preparer of
      Acquiror's or Indemnitor's Tax Returns or financial statements)
      acceptable to Indemnitor and Acquiror. In the event that the parties are
      unable to agree on an acceptable accounting firm, each shall select one
      accounting firm as its representative and the two accounting firms so
      selected shall select a third firm to perform the requisite
      verification. In order to enable such accountants to verify the basis
      and accuracy of such claim, Acquiror and Indemnitor shall provide to
      such accountants all information reasonably necessary for such
      verification, including without limitation any computer analyses used by
      Acquiror or Indemnitor to calculate or question, as the case may be,
      such amount or amounts. In conducting its verification, the accounting
      firm shall consult with, and consider in good faith the opinions and
      positions of, Acquiror and Indemnitor as to the proper resolution of any
      matters at issue. The review and determination of such calculations by
      such accounting firm pursuant to this Section 3(d) shall be final. The
      parties hereto agree that, if the accounting firm is required to resolve
      any matters relating to the computations, the accounting firm (i) shall
      provide Acquiror and Indemnitor with a written notification that
      describes in reasonable detail the matter or matters at issue, and (ii)
      prior to its resolution of the matter or matters at issue, shall provide
      Acquiror and Indemnitor with an opportunity to set forth their positions
      concerning the proper resolution of the matter or matters at issue in
      accordance with a procedure reasonably acceptable to both Acquiror and
      Indemnitor. The cost of such verification shall be borne by Indemnitor
      unless it is the determination of such verification that the actual
      amount or amounts payable (exclusive of interest and penalties)
      deviates, in a manner favorable to Indemnitor, by more than 10% from the
      amount originally determined by Acquiror, in which case such cost shall
      be borne by Acquiror.

                  (e)   At the request and expense of Indemnitor, Acquiror
      shall seek any refund of any Tax. In the event Acquiror receives a
      refund of (i) any amount which gave rise to an indemnification payment
      hereunder, or (ii) any Tax paid by Company prior to the Closing Date
      with respect to a Pre-Closing Period or Straddle Period, Acquiror shall
      refund such indemnification payment to Indemnitor; provided, however,
      that if either party has notified the other that there may be an amount
      due to Acquiror from Indemnitor pursuant to this Agreement or the
      Purchase Agreement, Acquiror may withhold payment until resolution of
      that claim has occurred.

                  (f)   Acquiror agrees not to file any amended return of the
      Company, or any of its affiliates with respect to a Pre-Closing Period
      or Straddle Period without the prior written consent of the Indemnitor.

                  (g)   The Indemnity Amount shall be reduced for the Tax
      benefits from any net operating loss carryover or other Tax attributes
      of the Company or the Company Subsidiaries as of the Closing that
      Acquiror or its Affiliates actually utilize after the Closing. To the
      extent that Acquiror or an Affiliate realizes an actual Tax benefit as a
      result of the event giving rise to the indemnity payment hereunder (such
      as, by way of example but not limitation, a savings in Federal income
      Taxes resulting from an increase in deductible state Taxes that are
      indemnified, in a case in which the indemnity payment itself does not
      give rise to gross income for Federal income tax purposes), Acquiror
      shall promptly rebate to Indemnitor the amount of such Tax benefit.

            Section 4.  Exclusions. (a) Notwithstanding any other provision of
this Agreement, Indemnitor shall not have any liability for indemnification
under this Agreement for any Tax liability attributable, in whole or in part,
to:

                        (i)   any fraud, willful misconduct or gross
      negligence of Acquiror or officer, director, employee or agent thereof;

                        (ii)  any Tax resulting from a determination that
      Acquiror is not treated as the owner of the Leased Property for income
      tax purposes (including, but not limited to, any adverse effect on
      Acquiror's status as a REIT); or

                        (iii) the willful failure of Acquiror to comply on a
      timely basis with certification, information, documentation, reporting
      or other similar requirements imposed on such Acquiror, or the willful
      failure of Acquiror to comply with its obligations set forth in Section
      5, to the extent Indemnitor demonstrates that its ability to contest
      such Tax liability is actually prejudiced by such willful failure of
      Acquiror.

                  (b)   Acquiror, Indemnitor and Seller agree, for themselves
      and on behalf of their respective existing and future affiliates and
      representatives, that notwithstanding any provision to the contrary in
      this Agreement, the Purchase Agreement or any other Transaction
      Agreement, with respect to each indemnification obligation in this
      Agreement, in no event shall the Indemnitor have liability to the
      Acquiror for any punitive, incidental, indirect or consequential
      damages, damages for the loss of profits or other special damages
      (including, but not limited to, any adverse effect on Acquiror's status
      as a REIT, unless such failure is due to Indemnitor's or Seller's
      willful misconduct, recklessness or gross negligence), and in no event
      shall Taxes (subject to the immediately preceding parenthetical clause)
      include any of the foregoing.

                  (c)   Notwithstanding anything to the contrary in this
      Agreement, no liability shall be imposed upon Indemnitor for any
      liability for Taxes for amounts that are required to be paid by
      Indemnitor, or any affiliate, as Tenant, to Acquiror, or any of its

                                       5
<PAGE>

      affiliates, as Landlord, under the Transaction Documents, including but
      not limited to transfer and similar Taxes relating to the transactions
      contemplated thereunder.

                  (d)   Notwithstanding anything to the contrary in this
      Agreement or any other Transaction Agreement, Seller shall have no
      liability for Taxes to the Acquiror or any of its affiliates.

                  (e)   Notwithstanding anything to the contrary in this
      Agreement, Indemnitor shall not be liable for any Taxes arising from
      transactions that occur following the Closing, including transactions
      occurring on the Closing Date after the Closing, and Acquiror shall not
      be liable for any Taxes of the Company and the Company Subsidiaries
      arising from transactions that occur at or preceding the Closing.

            Section 5.  Preparation of Tax Returns. Indemnitor will be
responsible for the preparation and filing of all Tax Returns for Company and
the Company Subsidiaries for all Pre-Closing Periods, and will pay all
third-party costs and expenses incurred in preparing and filing such Tax
Returns. Acquiror will be responsible for the preparation and filing of all
Tax Returns for Company and the Company Subsidiaries for all Post-Closing
Periods and any Tax period that includes a Straddle Period. All Tax Returns of
the Company and the Company Subsidiaries for any Pre-Closing Period and any
Straddle Period shall be prepared in a manner consistent with the applicable
entity's past practices as in effect prior to the Closing Date; provided,
however, that such past practices are in accordance with the Code and the
regulations thereunder. Acquiror shall submit any Tax Return that includes a
Straddle Period to Indemnitor for review and consent, which consent shall not
be unreasonably withheld. Each of Acquiror, Seller and Indemnitor agrees to
reasonably cooperate in making available information necessary to the
preparation and filing of such Tax Returns and each agrees to make available,
at its expense, records and employees of Company, Indemnitor, Seller and
Acquiror necessary for the preparation or such Tax Returns. Acquiror and its
accountants will be provided for their review, a draft of each material Tax
Return with respect to any period (or portion thereof) ending on or before the
Closing Date at least 20 days prior to the date Indemnitor intends to file
such Tax Return. To the extent that positions previously taken on Tax Returns
of the Company and the Company Subsidiaries require further explication or
substantiation in order for the Acquiror to prepare Tax Returns with respect
to Post-Closing Periods, the Indemnitor and the Seller shall provide or cause
to be provided such information and background with respect to such matters as
the Acquiror may from time to time reasonably request.

            Section 6.  Contests Pertaining to Tax.

                  (a)   Acquiror shall promptly notify Indemnitor (but in no
      event later than 5 Business Days following the receipt by Acquiror) of
      (i) the assertion of any claim or any dispute of any Tax reporting
      position, the commencement of any audit or examination of Company or any
      Company Subsidiary by any Tax Authority with respect to any Pre-Closing
      Period or Straddle Period and (ii) the receipt by it from the Internal
      Revenue Service of a written, proposed or final revenue agent's report,
      a 30-day letter or a notice of deficiency (as described in 6212 of the
      Code) or similar written notice from a Tax authority of a state, local,
      or foreign government, in which an adjustment is proposed or determined
      to the Taxes for which Indemnitor may be required to provide

                                       6
<PAGE>

      indemnification pursuant to this Agreement (a "Tax Claim"); provided,
      however, that any failure to provide such notice shall not relieve
      Indemnitor of any obligation to indemnify Acquiror hereunder except,
      notwithstanding anything to the contrary contained in Section 4(iii), to
      the extent that the Indemnitor's ability to contest such adjustment is
      prejudiced in Indemnitor's discretion by such failure of the Acquiror.

                  (b)   Indemnitor shall have the sole right to represent the
      interests of the Company and the Company Subsidiaries, and to settle any
      dispute with respect to Taxes arising, in any Tax audit or
      administrative or court proceeding relating to Pre-Closing Periods or to
      any Straddle Period of the Company or any Company Subsidiary, as the
      case may be, and to employ counsel of Indemnitor's choice at
      Indemnitor's expense to carry out such representation; provided,
      however, that Indemnitor shall notify Acquiror of its intention to
      represent such interests within ten (10) Business Days of Indemnitor's
      receipt of the notice from Acquiror in accordance with Section 6(a).
      Acquiror agrees that it will cooperate fully with Indemnitor and
      Indemnitor's counsel in the defense against or compromise of any claim
      in any said proceeding. Acquiror shall execute and deliver to Indemnitor
      any power of attorney or other document requested by Indemnitor in
      connection with any audit or administrative or court proceeding with
      respect to which Indemnitor is representing the interests of the Company
      or any Company Subsidiary (or successor-in-interest) in any proceeding
      described in this Section 6. In connection with any audit or
      administrative or court proceeding with respect to which Indemnitor is
      representing the interests of the Company or any Company Subsidiary (or
      any successor-in-interest), Indemnitor shall consult in good faith with,
      and keep reasonably informed, Acquiror and its counsel and shall provide
      Acquiror with copies of any documents, reports or claims issued by or
      sent to the relevant auditing agent or Tax Authority, as well as a
      reasonable opportunity to review and comment thereon, but the decisions
      regarding what actions are to be taken shall be made by Indemnitor in
      its reasonable judgment, taking into account the reasonable requests and
      interests of the Acquiror.

                  (c)   Acquiror shall not make payment of any claim for at
      least ten (10) days after giving written notice of such claim to
      Indemnitor if such forbearance is permitted by law. If the conduct of
      the contest requires Acquiror to pay the tax claimed and file or sue for
      a refund, Indemnitor shall advance to such Acquiror, on an interest-free
      basis, sufficient funds to pay the tax and any interest, penalties and
      additions to tax payable with respect thereto (to the extent such amount
      is subject to Indemnitor's indemnity obligations hereunder). Acquiror
      shall as promptly as practicable use such funds to pay such tax,
      interest, penalties or additions to tax, as the case may be.

                  (d)   If Acquiror receives any settlement offer from the
      Internal Revenue Service or similar notice from a Tax authority of a
      state, local, or foreign government with respect to a claim for which
      Acquiror seeks indemnity from Indemnitor, such Acquiror shall promptly
      inform Indemnitor of the receipt of such settlement offer. If Indemnitor
      recommends acceptance of such settlement offer, but Acquiror declines to
      accept such offer in writing within thirty (30) days: (i) the obligation
      of Indemnitor to make indemnity payments under this Agreement as the
      result of any such contest or proceedings shall not exceed the
      obligation that it would have had if such contest had been settled or
      proceeding terminated on such date on the basis of the settlement offer
      the

                                       7
<PAGE>

      acceptance of which was recommended by Indemnitor; and (ii) Indemnitor
      shall have no further liability for costs or other expenses in respect
      of such contest. Acquiror shall not settle any claim without
      Indemnitor's consent; provided, however, that Acquiror shall not be
      required to contest any proposed adjustment and may settle any such
      proposed adjustment if (i) Acquiror shall waive its right to indemnity
      with respect to such adjustment and shall refund to Indemnitor any
      amount previously paid or advanced by Indemnitor with respect to such
      adjustment or the contest of such adjustment.

                  (e)   If Indemnitor shall have duly complied with all the
      terms of this Section 6, Indemnitor's liability for indemnification, if
      any, under Section 3(a), shall be deferred (subject to the provisions of
      Section 6(c) hereof) until a Final Determination of the liability of
      such Acquiror. At such time, Indemnitor shall become obligated for the
      payment of any indemnification hereunder resulting from the outcome of
      such contest, and Acquiror shall become obligated to refund to
      Indemnitor any amount received as a refund by Acquiror or credited to
      Acquiror attributable to advances by Indemnitor hereunder. Within thirty
      (30) days following such Final Determination, any amounts due hereunder
      shall be paid first by set off against each other and either (i)
      Indemnitor shall pay to Acquiror any excess of the full amount due
      hereunder over the amount of any advances previously made by Indemnitor
      and applied against Indemnitor's indemnity obligation as aforesaid or
      (ii) Acquiror shall repay to Indemnitor any excess of such advances over
      such full amount due hereunder, together with the portion of any
      interest received by such Acquiror that is properly attributable to such
      excess amount of such advances during the period such advances were
      outstanding, and, if Indemnitor shall have indemnified such Acquiror
      with respect to the adverse tax consequences of any advances or payments
      hereunder, the amount of tax savings, if any, resulting from any payment
      pursuant to this sentence.

            Section 7.  Cooperation. Acquiror agrees to consider in good faith
any action (including filing claims for refund and amended Tax Returns) which
it is reasonably requested to take by Indemnitor that would minimize the net
amount of any indemnity payment due from Indemnitor hereunder.

            Section 8.  Treatment of Payments. The parties hereto shall, for
all tax and financial accounting purposes, to the extent permitted by law,
treat the assumption and payment of liabilities hereunder by Indemnitor as a
distribution by Indemnitor to the Company occurring prior to the Closing, and,
accordingly, as not includible in the taxable income of Acquiror.
Correspondingly, the parties hereto shall, for all tax and financial
accounting purposes, to the extent permitted by law, treat any payment
hereunder from Acquiror to Indemnitor as a capital contribution by the Company
to Indemnitor occurring prior to the Closing, and, accordingly, as not
includible in the taxable income of Indemnitor.

            Section 9.  Elections. So long as the Company and the Company
Subsidiaries remain incorporated as corporations under applicable law, the
Acquiror will not elect to treat Company or its wholly-owned direct or
indirect corporate subsidiaries as anything other than a qualified REIT
subsidiary pursuant to Section 856(i) of the Code. Notwithstanding the
preceding sentence, the Acquiror may, after Closing, cause the Company and one
or more of the Company Subsidiaries to convert from corporations into limited
liability companies pursuant to

                                       8
<PAGE>

state law. To such extent, the Company and any such Company Subsidiaries that
are wholly-owned, directly or indirectly, by Company, shall thereafter be
treated as disregarded entities for Federal income Tax purposes and, to the
extent permitted thereby, for purposes of applicable state, local and foreign
Taxes. Acquiror may also transfer ownership of such disregarded entities to an
entity controlled by the Acquiror that is classified as a partnership or as a
disregarded subsidiary of Acquiror for Federal income Tax purposes. The
parties hereto shall treat the Tax year of the Company, and, to the extent
permitted by law, of any Company Subsidiaries, as ending on the Closing Date
for Federal income Tax purposes and, to the extent permitted by law, for all
state, local and foreign Tax purposes, and shall take no position inconsistent
therewith.

            Section 10. Notices. All notices, demands, declarations, consents,
directions, approvals, instructions, requests and other communications
required or permitted by the terms of this Agreement shall be given in the
same manner as in the Purchase Agreement.

            Section 11. Miscellaneous.

                  (a)   Except as otherwise provided herein, the terms and
      conditions of this Agreement shall be binding upon and inure solely to
      the benefit of the parties hereto and their respective successors and
      assigns, and nothing in this Agreement, express or implied, is intended
      to confer upon any party other than the parties hereto or their
      respective successors and assigns any rights or remedies of any nature
      whatsoever under or by reason of this Agreement.

                  (b)   THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND

      INDEMNITOR AND ACQUIROR AGREES IRREVOCABLY AND UNCONDITIONALLY TO:

                        (i)   submit for itself and its property in any Action

      the United States of America for the Southern District of New York, and
      appellate courts having jurisdiction of appeals from any of the
      foregoing, and agrees that all claims in respect of any such Action
      shall be heard and determined in such New York State court or, to the
      extent permitted by law, in such federal court;

                        (ii)  consent that any such Action may and shall be
      brought in such courts and waives any objection that it may now or
      hereafter have to the venue or jurisdiction of any such Action in any
      such court or that such Action was brought in an inconvenient court and
      agrees not to plead or claim the same;

                                       9
<PAGE>

                        (iii) waive all right to trial by jury in any Action
      (whether based on contract, tort or otherwise) arising out of or
      relating to any of this Agreement, or its performance under or the
      enforcement of this Agreement;

                        (iv)  agree that service of process in any such Action
      may be effected by mailing a copy of such process by registered or
      certified mail (or any substantially similar form of mail), postage
      prepaid, to such party at its address as provided in Section 10; and

                        (v)   agree that nothing in this Agreement shall
      affect the right to effect service of process in any other manner
      permitted by the Laws of the State of New York.

                  (c)   This Agreement may be executed in two or more
      counterparts, each of which shall be deemed to be an original, but all
      of which shall constitute one and the same agreement.

                  (d)   When a reference is made in this Agreement to
      Sections, such reference shall be to a Section of this Agreement, unless
      otherwise indicated. The headings contained in this Agreement are for
      reference purposes only and shall not affect in any way the meaning or
      interpretation of this Agreement. Whenever the words "include,"
      "includes" or "including" are used in this Agreement, they shall be
      deemed to be followed by the words "without limitation."

                  (e)   Except as described in Sections 3, 5 and 6 above, each
      party shall pay all costs and expenses that it incurs with respect to
      the negotiation, execution, delivery and performance of this Agreement.
      If any action at law or in equity is necessary to enforce or interpret
      the terms of this Agreement, the prevailing party shall be entitled to
      reasonable attorneys' fees, costs and necessary disbursements in
      addition to any other relief to which such party may be entitled.

                  (f)   Any term of this Agreement may be amended, and the
      observance of any term of this Agreement may be waived (either generally
      or in a particular instance and either retroactively or prospectively),
      only with the written consent of Acquiror and Indemnitor.

            Section 12. Term. Except as otherwise provided herein, with
respect to indemnification under Section 3(a) for Taxes, the term of this
Agreement shall extend from the date hereof until such time as the applicable
statute of limitations (including any extensions thereof) bars a claim by the
Internal Revenue Service or relevant foreign, state or local Tax authority for
a Tax otherwise indemnifiable under this Agreement.

            Section 13. Termination. This Agreement shall automatically
terminate upon the termination of the Purchase Agreement in accordance with
its terms. In the event of the termination of this Agreement pursuant to this
Section 13, except as expressly provided in the Purchase Agreement, no party
hereto shall have any liability to any other party with respect to this
Agreement or the transactions contemplated hereby and this Agreement shall be
of no further force or effect.

            Section 14. Release. Acquiror, Indemnitor and their respective
existing and future Affiliates (collectively, the "Releasing Parties") do
hereby absolutely release and discharge Seller and its existing and future
Affiliates and Representatives (collectively, the "Releasees") from any and
all claims, actions, causes of action, suits, debts, dues, sums of money,
accounts, reckonings, bonds, bills, covenants, contracts, controversies,
agreements, demands, costs and judgments of whatsoever kind or nature, whether
known or unknown, absolute or contingent, direct or indirect at law or in
equity, which any of the Releasing Parties ever had or now has or have or
hereafter can, shall or may have, for, upon or by reason of any matter, cause
or thing whatsoever to the extent arising from, in connection with, related to
or as a result of (a) the Purchase Agreement and the transactions contemplated
thereby and the consummation thereof, relating to any period from the
beginning of the world to the end of time, regardless of when brought, (b) the
Transaction Agreements and the transactions contemplated thereby and the
consummation thereof, relating to any period from the beginning of the world

thereof) and Sections 5.04(a) and 7.06 of the Purchase Agreement.

            Section 15. Severability. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced under any Law or
as a matter of public policy, all other conditions and provisions of this
Agreement shall nevertheless remain in full force and effect so long as the
economic or legal substance of the transactions contemplated by this Agreement
is not affected in any manner materially adverse to any party. Upon such
determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties to this Agreement shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in a mutually acceptable manner in order that
the transactions contemplated by this Agreement be consummated as originally
contemplated to the greatest extent possible.

            Section 16. Entire Agreement. Except as otherwise provided in this
Agreement, or as otherwise expressly agreed in writing by the parties, this
Agreement and the other Transaction Documents constitute the entire agreement
and supersede all other prior or contemporaneous oral or written agreements
and understandings among the parties, or any of them, with respect to the
subject matter hereof, and there are no warranties, representations or other
agreements, express or implied, made to any party by any other party in
connection with the subject matter hereof or thereof except as specifically
set forth herein or therein or in the documents delivered pursuant hereto or

                                       3
<PAGE>

            (c)   Schedule 2.03 lists each of the Real Property Assets and
sets forth the portion of the Base Purchase Price that is allocable to each of
the Real Property Assets (each, an "Allocable Portion"); provided, that,
Acquiror will revise Schedule 2.03 to reflect adjustments, if any, to the
Allocable Portions of the Acquired Real Property Assets pursuant to Sections
2.09(d) and 10.02. The Allocable Portions shall be the basis upon which the
initial Lease Basis (as defined in the form of Property Lease) is determined
for each of the Acquired Real Property Assets; provided, that upon any
decrease in the Non-ALSF Purchase Price or the ALSF Purchase Price pursuant to
Sections 9.01 or 9.02, the Allocable Portion shall be adjusted by the Excluded
Real Property Basis Adjustment.

            Section 2.04.  Adjustments and Apportionments. (a) Seller and
Acquiror acknowledge and agree that, as of each Closing Date, certain costs
and expenses relating to the Acquired Real Property Assets being acquired by
Acquiror on such Closing Date, including real estate Taxes, water meter and
water charges, sewer rents, and debt service under the Assumed Mortgage Debt
(all such costs and expenses, collectively, "Real Property Expenses"), (x) may
have accrued during the period prior to such Closing Date (the "Pre-Closing
Period") but will not be due and payable by the Seller or a Company until
after such Closing Date (such accrued expenses, if any, that are unpaid as of
each Closing Date being hereinafter referred to as "Accrued Expenses") or (y)
will not accrue until the period on or after such Closing Date (each, a
"Post-Closing Period") but have been paid by the Seller or a Company during
the Pre-Closing Period (such unaccrued expenses, if any, that have been
prepaid as the Closing Date being hereinafter referred to as "Prepaid
Expenses"). The expenses described in this Section 2.04(a) shall be pro rated
as of 12:01 am (New York time) on each Closing Date and apportioned (on the
basis of a 365-day year) to (i) Seller with respect to the Pre-Closing Period
and (ii) Acquiror with respect to the Post-Closing Period (it being
acknowledged and agreed by Seller and Acquiror that each of the Net Tenants
shall, pursuant to the terms of the respective Property Leases, be responsible
for all Real Property Expenses relating to each of the Acquired Real Property
Assets leased by such Net Tenant with respect to the Post-Closing Period,
other than debt service relating to the Post-Closing Period under the Assumed
Mortgage Debt, as set forth in the respective Property Leases).

            (b)   Not later than ten (10) Business Days prior to each Closing
Date, Seller shall prepare and deliver to Acquiror a written statement setting
forth, as of the anticipated Closing Date, a reasonably detailed good faith
calculation of the apportionments contemplated by Section 2.04(a) for each of
the Acquired Real Property Assets. Acquiror shall have the right to review
such written statement and shall notify Seller of any objection thereto within
three (3) Business Days after the receipt thereof. Seller and Acquiror shall
negotiate in good faith to attempt to resolve any such objection made by
Acquiror, provided that if such parties are unable to agree upon a reasonably
detailed calculation of such apportionments at least five (5) Business Days
prior to the applicable Closing Date, such dispute shall be resolved by a
nationally recognized accounting firm reasonably acceptable to each of Seller
and Acquiror. If Acquiror does not notify Seller of any such objection within
such three (3) Business Day period, Acquiror shall be deemed to have agreed
with the apportionments specified in Seller's written statement. If, after the
applicable Closing, an error or omission in the calculation of the
apportionments set forth above is found by one of the parties, such error or
omission shall be promptly corrected and the party receiving the over-payment
shall pay the amount of the over-payment to the party

                                       4
<PAGE>

entitled thereto. The foregoing obligation to correct apportionments shall
survive the applicable Closing for a period of one-hundred eighty (180) days.

            (c)   The Base Purchase Price shall be (i) reduced by the excess,
if any, of the aggregate amount of Accrued Expenses over the aggregate amount
of Prepaid Expenses and (ii) increased by the excess, if any, of the aggregate
amount of Prepaid Expenses over the aggregate amount of Accrued Expenses, as
such amounts are mutually agreed or finally resolved in accordance with
Section 2.04(b), in each case, without duplication as to any amounts paid or
payable by the Net Tenants under the Property Leases.

            (d)   Acquiror shall purchase the Non-ALSF Shares subject to the
obligations set forth in Schedule 2.04(d) hereof (the "Specified
Liabilities"), which Specified Liabilities shall not be deemed Excluded
Liabilities. At least three (3) Business Days prior to the First Closing Date,
Seller shall deliver to Acquiror payoff statements or other evidence
satisfactory to Acquiror as to the amount of the Specified Liabilities at the
First Closing (the aggregate amount of such Specified Liabilities being
hereinafter referred to as the "Pay-off Amount"), provided, that for purposes
of the last two sentences of Section 2.03, neither the Final Purchase Price,
the Allocable Portion nor the initial Lease Basis (as defined in the form of
Property Lease) shall be deemed reduced by any adjustments to the cash portion
of the Non-ALSF Purchase Price made pursuant to this Section 2.04(d). Acquiror
shall cause the applicable Company to pay the Specified Liabilities at the
First Closing.

            Section 2.05.  Due Diligence Deposit; Purchase Price Deposit .

            (a)   Prior to the execution of the Original Purchase Agreement,
Seller advanced to Acquiror a due diligence deposit in the amount of $125,000
(the "Due Diligence Deposit") to be used by Acquiror to pay any reasonable and
documented costs and expenses, including attorneys' fees and expenses,
incurred by Acquiror, its contractors and consultants in connection with
Acquiror's due diligence review of the Real Property Assets, the Seller and
the Companies (the "Due Diligence Review"). If the First Closing is not
consummated for any reason other than Seller's failure to perform its
respective obligations hereunder, then within ten (10) Business Days after the
termination of this Agreement, Acquiror shall repay to Seller the Due
Diligence Deposit, less any Transaction Costs incurred by Acquiror in
connection with the Due Diligence Review. If Seller fails to perform its
respective obligations hereunder, then Acquiror shall not be obligated to
return to Seller any portion of the Due Diligence Deposit. If the First
Closing is consummated, then Seller shall be entitled to set-off as of the
First Closing Date the Due Diligence Deposit against the Transaction Costs for
which Seller is responsible under this Agreement that have been incurred by
Acquiror.

            (b)   Upon the consummation of the Private Placement, Acquiror
shall advance or cause to be advanced to Seller cash in an amount equal to
$22,500,000 as a good faith, refundable deposit to be applied at the First
Closing against the Non-ALSF Purchase Price (the "Purchase Price Deposit").
If, prior to the First Closing, Seller or its Affiliates sell or otherwise
dispose of any Acquiror Securities acquired by Seller on the date of the
Amended Stock Purchase Agreement (such shares so sold or disposed, "Disposed
Securities"), then cash in the amount of the gross proceeds of such sale or
disposition (but not exceeding the initial purchase price paid by Seller and
its Affiliates for such Disposed Securities) shall be remitted to Acquiror

                                       5
<PAGE>

promptly after such sale or disposition and the Purchase Price Deposit shall
be reduced by a corresponding amount. If the transactions contemplated by this
Agreement are terminated for any reason prior to the First Closing, Seller
shall concurrently with such termination refund to Acquiror the balance of the
Purchase Price Deposit; provided, however, that Seller's obligation to refund
the balance of the Purchase Price Deposit may (at Seller's option) be
satisfied in full upon delivery to Acquiror of (x) any Acquiror Securities
acquired by Seller on the date of the Amended Stock Purchase Agreement which
are then held by Seller and its Affiliates and (y) cash equal to (A) the sum
of (i) any gross proceeds not remitted to Acquiror as provided above in
respect of Disposed Securities and (ii) the amount, if any, by which the
aggregate initial purchase price paid by Seller and its Affiliates for
Disposed Securities exceeds the aggregate gross proceeds received by Seller
and its Affiliates for Disposed Securities, less (B) dividends or
distributions, if any, declared on the Acquiror Securities delivered to
Acquiror in accordance with clause (x) above, and Acquiror shall have no other
recourse against Seller with respect to its obligation to refund the Purchase
Price Deposit.

            Section 2.06.  Transactions to be Effected; Closing and Other
Deliveries. Upon the terms and subject to the conditions set forth in this
Agreement:

            (a)   (i) At the First Closing, Acquiror shall pay to Seller (x) a
net amount (the "Non-ALSF Closing Amount") equal to the Non-ALSF Final
Purchase Price, less the then current balance of the Purchase Price Deposit,
less the Pay-off Amount, and (y) the Amendment Costs (as such term is defined
herein), by wire transfer of immediately available funds to an account
designated in writing by Seller at least three (3) Business Days prior to the
First Closing Date; and (ii) at the Second Closing, Acquiror shall pay to
Seller the ALSF Final Purchase Price by wire transfer of immediately available
funds to an account designated in writing by Seller at least three (3)
Business Days prior to the Second Closing Date;

            (b)   (i) At the First Closing, Seller shall deliver to Acquiror
(A) one or more stock certificates evidencing the Non-ALSF Shares, duly
endorsed in blank or accompanied by powers duly executed in blank in proper
form for transfer and (B) written resignations of each of the directors and
officers of each of ALS Venture, ALS West and AHC Borrower, and (ii) at the
Second Closing, Seller shall deliver to Acquiror (A) one or more stock
certificates evidencing the ALS Financing Shares, duly endorsed in blank or

(B) written resignations of each of the directors and officers of each of ALS
Financing;

            (c)   At each Closing, to further document the transactions
contemplated by this Agreement, each of Acquiror and the applicable Selling
Parties, as applicable, shall execute and deliver to each other each of the
following agreements to which it is a party: (i) the Property Leases; (ii) the
Agreement Regarding Leases; (iii) the Lease Guaranty; (iv) the Guaranty of
Agreement Regarding Leases; and (v) the Management Agreements (each of the
agreements referenced in clauses (i) through and including (v), together with
this Agreement and the Tax Matters Agreement, being hereinafter referred to
collectively as the "Transaction Agreements");

            (d)   Seller and Acquiror shall jointly prepare and deliver final
closing statements (the "Closing Statements") setting forth (i) the Non-ALSF
Final Purchase Price and the Non-ALSF Closing Amount, and including a
reasonably detailed calculation of each of (x)

                                       6
<PAGE>

the components of the Non-ALSF Purchase Price (other than the Non-ALSF Base
Purchase Price), (y) the Non-ALSF Closing Adjustments, if any, all as
determined in accordance with the applicable provisions of this Agreement and
(z) the Specified Liabilities, and (ii) the ALSF Final Purchase Price, and
including a reasonably detailed calculation of each of (x) the components of
the ALSF Purchase Price (other than the ALSF Base Purchase Price), and (y) the
ALSF Closing Adjustments, if any, all as determined in accordance with the
applicable provisions of this Agreement; and

            (e)   At each Closing, Seller shall deliver, or shall cause to be
delivered, to Acquiror each of the following:

                  (i)   each (A) New Title Policy (or endorsements (including
      non-imputation endorsements) to the existing owner's policies), if any,

      applicable Company at such Closing and in form and substance acceptable
      to the applicable title company, and (B) New Survey, if any, in each
      case, required to be delivered pursuant to Section 2.10;

                  (ii)  an affidavit, in accordance with the Foreign

                  (iv)  such other documents and instruments as may reasonably
      be required by Acquiror or the applicable title company in order to
      consummate the transactions contemplated by this Agreement and to
      otherwise effect the agreements of the parties pursuant to this
      Agreement.

            (f)   In addition to the foregoing, at or prior to each Closing,
(i) Seller will deliver to Acquiror the certificate referred to in Section
6.02(a)(iii), and (ii) Acquiror will deliver to Seller the certificate
referred to in Section 6.01(a)(iii).

            Section 2.07.  Payments and Computations. All payments to be made
by either party under this Agreement will be paid by wire transfer of
immediately available funds to the account or accounts designated by the party
receiving such payment. All computations of interest with respect to any

the basis of a year of 365 days, in each case for the actual number of days
(excluding the first day, but including the last day) occurring in the period
for which such interest is payable.

            Section 2.08.  Property Due Diligence. (a) Promptly following the
execution of the Original Stock Purchase Agreement, Acquiror shall deliver to
Seller a due diligence document request and checklist (which may be
supplemented from time to time during the Review Period) identifying the
materials requested to be reviewed by Acquiror in connection with the Due
Diligence Review. Not later than fifteen (15) days after the date of the
Original

                                       7
<PAGE>

Stock Purchase Agreement, Seller shall cause the Companies to make available
to Acquiror, its attorneys, accountants and other professional and
consultants, copies of all books, records, documents, reports, analyses,
assessments and other written material relating to each of the Real Property
Assets, including all title insurance policies, surveys, engineering and
environmental reports, operating and capital statements, rent rolls and all
other due diligence materials reasonably requested by Acquiror in connection
with the Due Diligence Review.

            (b)   Acquiror shall have a period (the "Review Period") of sixty
(60) days from the date of the Original Stock Purchase Agreement (the
expiration date of such period being hereinafter referred to as the "Due
Diligence Expiration Date") to complete the Due Diligence Review (including
obtaining and reviewing title commitments or title bring-downs and engineering
reports, environmental reports and surveys relating to the Real Property
Assets). If Acquiror, in its reasonable discretion, determines that any
material matter relating to any of the Real Property Assets (including leases,
historical and projected financial statements and information, operating and
capital statements, title, real estate tax information, billings and
collections, operating and real estate tax pass-through escalation
calculations, survey, engineering, fitness and quality, physical condition,
environmental condition, financial condition of one or more of the tenants,
value and profitability, current or potential uses, current or future zoning
or suitability for renovation or construction) is not acceptable to Acquiror
and that it does not wish to proceed with its acquisition of such Real
Property Asset, then Acquiror may, by written notice to Seller before 5:00
p.m. (New York time) on the Due Diligence Expiration Date (time being of the
essence), terminate the Original Stock Purchase Agreement in its entirety,
whereupon the Original Stock Purchase Agreement shall terminate and be of no
further force and effect as provided in Article VII. If Acquiror does not
elect to terminate the Original Stock Purchase Agreement prior to the time set
forth above, Acquiror's right to terminate the Original Stock Purchase
Agreement pursuant to this Section 2.08(b) shall expire and be of no further
force and effect.

            (c)   Seller shall use reasonable commercial efforts during the
Review Period to permit Acquiror and its Representatives, upon prior
reasonable notice to Seller, and during normal business hours, to access each
of the Real Property Assets for the purpose of inspecting the Real Property
Assets. Seller agrees that any environmental investigation undertaken by
Acquiror may include invasive sampling of soil, groundwater, or parts of
buildings or structures, on any Real Property Asset occupied by or otherwise
affiliated with the Companies without Seller's prior written consent;
provided, however, that Acquiror shall give Seller not less than twenty-four
(24) hours' prior notice thereof (which notice shall include the identity of
the Representatives of Acquiror that will perform such inspections and the
proposed scope thereof) and Seller or its respective Representatives shall
have the right to be present during such inspections. Acquiror shall use
reasonable commercial efforts not to interfere in any material respect with
Seller's use or operation of the Real Property Assets during such inspections.
If Acquiror takes, or causes to be taken, any sample from a Real Property
Asset in connection with the foregoing, Acquiror shall, upon the request of
Seller, provide to Seller a portion of such sample to allow Seller, if it so
chooses, to perform its own testing. If Acquiror performs environmental
sampling, Acquiror shall have Acquiror's environmental consultant carry and
maintain in force, at its expense, at all times during the performance of such
sampling, general liability insurance in the minimum amount of $1 million
combined single limit for injury to or death of one or more persons per
occurrence and for damage to property per occurrence.

                                       8
<PAGE>

Notwithstanding any provisions of this Agreement to the contrary, Acquiror
shall not, and shall cause its environmental consultant not to, contact or
communicate with any Governmental Authority regarding any Hazardous Materials
on any Real Property Asset, or the environmental condition of any Real
Property Asset, unless required by Law; provided, however, that such
restriction shall not apply following each Closing.

            Section 2.09.  Capital Expenditure Reserves. (a) The Base Purchase
Price was agreed upon between Seller and Acquiror on the assumption that none
of the Real Property Assets is in need of significant deferred maintenance
expenditures, and that the annual capital expenditure requirement of $400 per
unit, which will be set forth in and calculated pursuant to the Agreement
Regarding Leases, is sufficient to provide for anticipated future capital
expenditures to maintain each of the Real Property Assets in their current
condition. If, during the course of the Due Diligence Review in respect of any
Real Property Asset, Acquiror determines, pursuant to third party reports
received by Acquiror (each, an "Acquiror Cap Ex Report"), that the anticipated
costs to perform deferred maintenance and previously unidentified future
capital expenditures reasonably necessary to be performed during the twelve
(12) month period following each Closing Date will exceed the amount of the
capital expenditure requirement for such period as set forth in and calculated
pursuant to the form of Agreement Regarding Leases (the amount of such excess,
with reference to any Real Property Asset, being hereinafter referred to as
the "Cap Ex Reserve Shortfall"), then Acquiror shall provide to Seller not
later than five (5) Business Days after the Due Diligence Expiration Date a
written statement specifying the Cap Ex Reserve Shortfall, if any, for each of
the Real Property Assets, including copies of all Acquiror Cap Ex Reports
supporting such determination. Acquiror shall provide copies of each Acquiror
Cap Ex Report as promptly as practicable after such report shall have been
received by Acquiror. If Acquiror does not timely notify Seller of any Cap Ex
Reserve Shortfall in respect of a Real Property Asset as provided above,
Acquiror shall be deemed to have agreed that the amount of the Cap Ex Reserve
Shortfall in respect of such Real Property Asset is zero.

            (b)   For a period of ten (10) Business Days after the receipt of
the statement delivered by Acquiror in accordance with Section 2.09(a), Seller
shall have the right to review the statement and to obtain its own third party
reports relating to any specified Cap Ex Reserve Shortfall (each such report,
a "Seller Cap Ex Report"). Seller shall provide copies of each Seller Cap Ex
Report as promptly as practicable after such report shall have been received
by Seller. If Seller objects to any Cap Ex Reserve Shortfall specified in
Acquiror's statement in respect of any Real Property Asset and determines,
pursuant to a Seller Cap Ex Report, that the amount of such Cap Ex Reserve
Shortfall is overstated by more than five percent (5%), then Seller shall
provide to Acquiror not later than five (5) Business Days after the expiration
of such review period a written statement specifying the amount of such
overstatement for each of the Real Property Assets, including copies of all
Seller Cap Ex Reports supporting such determination. If Seller does not notify
Acquiror in writing of any objection within such review period, Seller shall
be deemed to have agreed to the amount of each Cap Ex Reserve Shortfall
specified in Acquiror's statement.

            (c)   Seller and Acquiror shall negotiate in good faith to attempt
to resolve any such objection that is timely made by Seller, provided that if
such parties are unable to agree upon the amount of the Cap Ex Reserve
Shortfall for any Real Property Asset within ten (10)

Business Days after the date of the written statement sent by Seller
specifying an overstatement, Seller and Acquiror shall cause the preparers of
the applicable Acquiror Cap Ex Report and the applicable Seller Cap Ex Report
to select an independent third party to provide a capital expenditure report
for such Real Property Asset and the amount of the Cap Ex Reserve Shortfall
specified in such independent report shall be final and binding on Acquiror
and Seller for the purposes of this Section 2.09. The fees and expenses of any
such independent third party shall be a Transaction Cost.

            (d)   Upon Seller and Acquiror having agreed or deemed to have
agreed upon the amount of the Cap Ex Reserve Shortfall (or such amount having
been determined in accordance with Section 2.09(c)), Seller may, at its sole
option: (i) decrease the Base Purchase Price by the amount of the Cap Ex
Reserve Shortfall so agreed or determined; (ii) deposit into escrow (with a
third party mutually acceptable to Seller and Acquiror pursuant to escrow
instructions in form and substance reasonably acceptable to Seller and
Acquiror) on each Closing Date the amount of the Cap Ex Reserve Shortfall so
agreed or determined for disbursement to Acquiror (and its Affiliates) from
time to time after the applicable Closing Date to pay for the deferred
maintenance and capital items specifically identified in the applicable third
party reports; or (iii) direct Acquiror to perform (or to cause third parties
to perform) the deferred maintenance work and the capital items specifically
identified in the applicable third party reports, in which case the Allocable
Portions of the applicable Acquired Real Property Assets shall be increased in
the aggregate by the aggregate amount of the Cap Ex Reserve Shortfall so
agreed or determined (such increase to be allocated by Acquiror among the
applicable Acquired Real Property Assets in such manner as Acquiror shall
reasonably determine).

            Section 2.10.  New Title Policies; New Surveys. During the Review
Period, Acquiror shall have the opportunity to review the existing owner's
title insurance policies and surveys of the Real Property Assets. If, upon
such review, Acquiror shall reasonably determine that the existing owner's
title insurance policy for any Real Property Asset is insufficient to protect
the interests of Acquiror with respect to such Real Property Asset and
Acquiror delivers notice thereof to Seller on or before the Due Diligence
Expiration Date specifying the applicable Real Property Asset and identifying
the interests of Acquiror that are not protected, Seller shall, at its option
and at its sole cost and expense, cause either (a) the title insurance company
that issued the existing owner's title insurance policy for the applicable
Real Property Asset to issue to Acquiror, on each Closing Date, relevant
endorsements to such existing title insurance policies in order to adequately
protect the interests of Acquiror, including a non-imputation endorsement, or
(b) a title insurance company reasonably selected by Seller to provide to
Acquiror on the applicable Closing Date an owner's title insurance policy (or
in the case of a New York-style closing, a marked title insurance commitment
representing such title insurance policy) covering title to the applicable
Real Property Asset in an amount approximating the fair market value thereof
(in either case, a "New Title Policy"). Similarly, if Acquiror shall
reasonably determine that the existing survey for any Real Property Asset is
insufficient to protect the interests of Acquiror with respect to such Real
Property Asset and Acquiror delivers notice thereof to Seller on or before the
Due Diligence Expiration Date specifying the applicable Real Property Asset
and identifying the interests of Acquiror that are not protected, Seller
shall, at its sole cost and expense, deliver to Acquiror, on or before each
Closing Date, a survey of the applicable Real Property Asset performed by a
surveyor licensed in the state in which such asset is located and certified to
Acquiror as having been prepared in accordance with 1999 minimum standard
details

                                      10
<PAGE>

for a land survey jointly adopted by ALTA/ACSM (a "New Survey"). If Acquiror
shall fail to deliver any written notice to Seller contemplated by this
Section 2.10 with respect to any Real Property Asset on or before the Due
Diligence Expiration Date, Acquiror shall be deemed to have waived its right
to request a New Title Policy or New Survey with respect to such Real Property
Asset.

            Section 2.11.  Real Property Matters to which Real Property May Be
Subject. At the First Closing, the Companies shall each own good and valid
insurable fee title to the Acquired Real Property Assets, free and clear of
any and all Liens other than Permitted Liens. At the Second Closing, ALS
Financing shall own good and valid insurable fee title to the ALSF Assets,
free and clear of any and all Liens other than Permitted Liens

            Section 2.12.  No Other Representations. No representation,
warranty or covenant made by Seller in this Agreement or any document
delivered pursuant to this Agreement shall survive either Closing except as
expressly provided in this Agreement. Acquiror has not relied upon, and Seller
is not liable or bound in any manner by, any verbal or written statements,
representations, real estate brokers' "set-ups" or information pertaining to
the Real Property Assets furnished by any real estate broker, agent, employee,
servant to other Persons unless the same are expressly set forth in this
Agreement.

Agreement do not, and the execution and delivery by Acquiror at each Closing
of the other Transaction Agreements to which Acquiror will be a party will
not, and the performance by Acquiror of, and the consummation by Acquiror of
the transactions contemplated by, each of the Transaction Agreements to which
Acquiror is or will be a party will not, require any Governmental Approval,
except where the failure to obtain such Governmental Approval, could
reasonably be expected to prevent or materially delay Acquiror from

                                      26

consummating the transactions contemplated by or performing any of its
material obligations under any of the Transaction Agreements to which Acquiror
is or will be a party.

            Section 4.05.  Securities Matters. The Shares are being acquired
by Acquiror for its own account and without a view to the public distribution
or sale of the Shares or any interest in them. Acquiror has sufficient
knowledge and experience in financial and business matters so as to be capable
of evaluating the merits and risks of its investment in the Shares, and
Acquiror is capable of bearing the economic risks of such investment,
including a complete loss of its investment in the Shares.

            Section 4.06.  Financial Ability. Acquiror intends to finance the
Final Purchase Price, in part, by issuing stock in Acquiror pursuant to a
private placement transaction (the "Private Placement") and, in part, by
obtaining third party financing pursuant to one or more credit facilities (the
"Debt Financing"). Subject to receipt of proceeds of at least $530,000,000
upon the consummation of the Private Placement and the Debt Financing,
Acquiror will have, at each Closing, the financial ability to consummate the
transactions contemplated by this Agreement.

            Section 4.07.  Investigation. Acquiror acknowledges and agrees
that it has made its own inquiry and investigation into, and, based thereon,
has formed an independent judgment concerning, the Real Property Assets, the
Companies and their respective businesses. Acquiror further acknowledges and
agrees that the only representations, warranties, covenants and agreements
made by Seller are the representations, warranties, covenants, and agreements
expressly set forth in this Agreement and the Tax Matters Agreement and Seller
makes and has made no other express or implied representation or warranty with
respect to the Real Property Assets (including with respect to title, physical
condition, environmental condition, fitness and quality, income and expenses
of operation, value and profitability, current or potential uses, current or
future zoning or suitability for renovation or construction), the Companies or
their respective businesses or otherwise or with respect to any other
information provided by Seller or any of its Affiliates or Representatives.
Acquiror has not relied upon any other representations or other information
made or supplied by or on behalf of Seller or by any Affiliate or
Representative of Seller. No officer of Acquiror has actual knowledge that the
representations and warranties of Seller set forth in Article III are
inaccurate or have been breached except for inaccuracies and breaches relating
to matters that, individually or in the aggregate, have not had, or would not
be reasonably expected to have, a Material Adverse Effect.

            Section 4.08.  Brokers. Neither Acquiror nor any of its Affiliates
has employed any broker or finder or incurred any liability for any investment
banking fees, brokerage fees, commissions or finders' fees in connection with
the transactions contemplated by this Agreement and the Tax Matters Agreement
for which Seller or any of its Affiliates has or could have any liability.

            Section 4.09.  Information Supplied. None of the information
supplied or to be supplied by or on behalf of Acquiror specifically for
inclusion in the Offering Memorandum or the Registration Statement will
contain, at any time the Offering Memorandum is distributed to prospective
investors or the Registration Statement becomes effective under the Securities
Act, as applicable, any untrue statement of a material fact or omit to state
any material fact required to

                                      27
<PAGE>

be stated therein or necessary to make the statements therein not misleading,
except that no representation or warranty is made by Acquiror with respect to
the information supplied by Seller specifically for inclusion in the Offering
Memorandum as set forth in Schedule 3.26. The Offering Memorandum and the
Registration Statement will comply as to form in all material respects with
the requirements of the Securities Act and the Exchange Act, and the rules and
regulations thereunder ("Applicable Securities Rules").

third party) to make available to the Representatives of Acquiror and its
Affiliates the employees of third party outsourcing companies who provide
services to, and are located on the premises of, the Companies, in each case,
whose assistance and expertise is necessary to assist Acquiror in connection
with Acquiror's preparation to integrate the Companies and their businesses
and personnel into Acquiror's organization following the applicable Closing;
provided, however, that such investigation shall be on a basis and follow
procedures that the parties shall mutually agree, and shall not unreasonably
interfere with any of the businesses or operations of Seller, the Companies or
any of their respective Affiliates; and provided, further, that the auditors
and accountants of Seller, the Companies or any of their respective Affiliates
shall not be obligated to make any work papers available to any Person unless
and until such Person has signed a

<PAGE>

customary agreement relating to such access to work papers in form and
substance reasonably acceptable to such auditors or accountants. If so
reasonably requested by Seller or any of the Companies, Acquiror shall enter

the Companies with respect to any information to be provided to Acquiror
pursuant to this Section 5.02(a).

appropriate to ensure compliance with any applicable Laws (including any
rights of any current or former employee of any of the Companies with respect
to privacy or confidentiality of such employee's personnel, medical and other

necessary to assist Seller or any of the respective Affiliates in connection
with Seller's inquiries for any of the purposes referred to above, including,
at Seller's sole cost and expense, reimbursement to Acquiror or such
Affiliates; provided, that the requesting party will reimburse Acquiror for
the reasonable value of the time and any out-of-pocket expenses of such
Persons who appear as witnesses in hearings or trials at the request of
Seller; provided, however, that such investigation shall be on a basis and
follow procedures that the parties shall mutually agree, and that such
investigation shall not unreasonably interfere with the business or operations
of Acquiror or any of its Affiliates; provided, further, that the auditors and
accountants of Acquiror or its Affiliates shall not be obligated to make any
work papers available to any Person unless and until such Person has signed a

reasonably requested by Acquiror, Seller or the applicable Affiliate thereof
shall enter into a customary joint defense agreement with Acquiror and its
Affiliates (including the Companies) with respect to any information to be
provided to Seller pursuant to this Section 5.02(b).

periods ending on or prior to the Closing Date on which such Company was
purchased by Acquiror, subject to compliance with all applicable privacy Laws
relating to information (including employment and medical records) regarding
current or former employees of any of the Companies. Acquiror agrees that,
with respect to all original

                                      31
<PAGE>

books and records of each of the Companies existing as of the Closing Date on
which such Company was purchased by Acquiror, it will (and will cause each of
the Companies to) (a) comply in all material respects with all applicable Laws
relating to the preservation and retention of records and (b) apply
preservation and retention policies to such books and records that are no less
stringent than those generally applied by Acquiror in respect of its other
books and records. Following each Closing, Seller shall promptly deliver to
Acquiror all original books and records of the Companies in the possession of
Seller or any of its Affiliates (other than such book and records in the
possession of the Acquired Companies).

            Section 5.04.  Confidentiality; Exclusivity.

            (a)   From the applicable Closing Date until December 31, 2005,
Seller and its Affiliates, on the one hand, and Acquiror and its Affiliates
(including the Acquired Companies), on the other hand, shall, and shall cause
their respective Representatives to maintain in confidence and not use to the
detriment of the other party (including for the purposes of competing with the
other party or its Affiliates), any written, oral or other information
relating to and obtained from the other party or its Affiliates, except that
the foregoing requirements of this Section 5.04(a) shall not apply to a party

to the public other than (A) in the case of Acquiror, as a result of
disclosure by Seller, its Affiliates or any of its respective Representatives
and (B) in the case of Seller, as a result of disclosure by Acquiror or any of
the Acquired Companies (after the applicable Closing Date) or any of their

such information is required by applicable Law, Governmental Order or a
Governmental Authority to be disclosed after prior notice that has been given
to Acquiror or Seller, as applicable, (iii) any such information is to be
disclosed in connection with any Action, or (iv) any such information was or
becomes available to such party on a non-confidential basis and from a source
(other than a party to this Agreement or any Affiliate or Representative of
such party) that is not bound by a confidentiality agreement. Seller and
Acquiror shall instruct its Affiliates and Representatives having access to
such information of such obligation of confidentiality.

            (b)   Acquiror and Seller agree to deal with one another on an
exclusive basis during the term of this Agreement with respect to the
transactions contemplated herein, and Seller shall not solicit or entertain
offers for, or enter into any discussions relating to, any similar
transactions with respect to the sale of the Companies or any of the Acquired
Real Property Assets.

            Section 5.05.  Regulatory and Other Authorizations; Reasonable
Efforts. (a) Subject to the terms and conditions of this Section 5.05, Seller
and Acquiror agree to use their reasonable best efforts to take, or cause to
be taken, all actions and to do, or to cause to be done, all things necessary,
proper, advisable or appropriate to consummate and make effective the
transactions contemplated by the Transaction Agreements as soon as
practicable, including to cooperate in good faith to facilitate each Closing
and to refrain from taking any action that could reasonably be expected to
cause a condition to either Closing to not be satisfied or otherwise
materially impair, delay or impede either Closing. In furtherance of the
foregoing, (a) promptly following the date of the Original Stock Purchase
Agreement, Seller shall prepare and deliver to Acquiror a written list of all
Seller Required Governmental Approvals to be obtained or made in

                                      32
<PAGE>

promptly make all filings and notifications with, and shall use their
reasonable best efforts to promptly obtain all authorizations, consents,
orders and approvals of, all Governmental Authorities that may be or become
necessary for their respective execution and delivery of, and the performance
of their respective obligations pursuant to, and the consummation of the
transactions contemplated by, this Agreement and comply at the earliest
practicable date with a request for information, documents or other materials
by any such Governmental Authorities to obtain such authorizations, consents,
orders and approvals; provided, however, that in no event shall Acquiror or
any of its Affiliates be required to agree to (i) the divestiture of any
business or entity or (ii) any requirement imposed by a Governmental Authority
that would reasonably be expected to have a (A) Material Adverse Effect taken
as a whole, or (B) material and adverse effect on the aggregate economic value
and business benefits that would reasonably be expected to be obtained by
Acquiror and its Affiliates from the transactions contemplated by this
Agreement. The parties will cooperate with the reasonable requests of each
other in promptly seeking to obtain all such authorizations, consents, orders
and approvals (including by making available, upon reasonable notice,
appropriate Representatives of the Companies for participation in meetings
with Governmental Authorities).

            (b)   Prior to each Closing, each of Seller and Acquiror shall
promptly notify one another of any communication it receives from any
Governmental Authority relating to the matters that are the subject of this
Agreement applicable to such Closing and permit the other party to review in
advance any proposed material written communication by such party to any
Governmental Authority and shall provide each other with copies of all
correspondence, filings or communications between such party or any of its
Representatives, on the one hand, and any Governmental Authority or members of
its staff, on the other hand; provided, however, that Acquiror or Seller, as
applicable, may redact from such correspondence, filings and communications
any confidential competitive information of Acquiror, Seller or their
respective Affiliates, as the case may be. Prior to each Closing, neither
Seller nor Acquiror shall agree to participate in any meeting with any
Governmental Authority in respect of any such filings, investigation or other
inquiry with respect to such Closing unless it consults with the other party
in advance.

            (c)   Seller and Acquiror shall use their reasonable best efforts
to obtain any other consents and approvals (including from any ground lessors
and from the holders of the Existing Mortgages, and to make any other
notifications that may be required in connection with the transactions
contemplated by this Agreement; provided, however, that, except for
Transaction Costs, none of Seller, the Companies or Acquiror shall be required
to compensate any third party, commence or participate in litigation or offer
or grant any accommodation (financial or otherwise) to any third party to
obtain any such consent or approval; provided, further, that Seller shall not
be required to incur (i) Transaction Costs (excluding any additional costs
("Additional Insurance Costs") of complying with insurance requirements
required by an Existing Mortgage Lender in order to obtain each of the written
consents and approvals of the Existing Mortgage Lenders in Schedule 5.10(a) in
form and substance satisfactory to Seller in its reasonable commercial
discretion (the "ASLF Consent") in excess of $1,000,000 or (ii) Transaction
Costs (including Additional Insurance Costs) in excess of $2,000,000 (the

            Section 5.06.  Intercompany Obligations. Seller shall, and shall
cause its Affiliates to, take such action and make such payments as may be
necessary so that, prior to or concurrently with each Closing Date, the
Company or Companies being acquired by Acquiror on such Closing Date, on the
one hand, and Seller and its Affiliates, on the other, shall settle,
discharge, offset, pay or repay in full all intercompany loans, notes and
advances (regardless of their maturity) and all intercompany receivables and
payables (including amounts relating to intercompany Tax sharing agreements,

however, that if each such item is not paid in full in cash, the method of
discharge must be reasonably satisfactory to Acquiror.

            Section 5.07.  Intercompany Arrangements. Except as otherwise
agreed in writing by Seller and Acquiror or as expressly provided in the
Transaction Agreements, Seller shall, and shall cause its Affiliates to, take

otherwise distribute to Seller or one of its wholly owned subsidiaries all of
such Company's right, title and interest in and to all the Excluded Assets,
and (ii) Seller shall, or shall cause, one of its wholly owned subsidiaries to
assume all the Excluded Liabilities. The distribution of the Excluded Assets
and the assumption of the Excluded Liabilities shall be effected pursuant to
written instruments of transfer and assumption, as applicable, reasonably

all of such Excluded Assets or Excluded Liabilities, as applicable, to a
direct or indirect Subsidiary of a Company followed by a distribution of the
Capital Stock of such Subsidiary.

            Section 5.09.  Additional Real Property Assets. Prior to the First
Closing, (i) Seller shall cause Winston to be merged with and into ALS Venture
and (ii) Seller shall transfer the FDL Real Property Asset to AHC Borrower, in

            Section 5.10.  Existing Mortgage Lender Consents. (a) The purchase
and sale of the ALS Financing Shares and the assumption of the debt
outstanding under the Existing Mortgages may require certain consents and
agreements of the Existing Mortgage Lenders set forth in Schedule 5.10(a).
Seller and Acquiror shall use their reasonable best efforts in accordance with
Section 5.05(c) to secure all such consents and agreements. Seller or Acquiror
will promptly notify the other if it reasonably believes that, notwithstanding
the parties' reasonable best efforts pursuant to Section 5.05(c), it will be
unable to obtain one or more of the consents of the Existing Mortgage Lenders
prior to the Extended Outside Date or that the ALSF Costs are reasonably
likely to exceed the ALSF Cap.

<PAGE>

            (b)   If any consent of an Existing Mortgage Lender in respect of
any Real Property Assets owned by ALS Financing ("ALSF Assets") shall not have
been obtained by the Extended Outside Date or if the ALSF Costs exceed the
ALSF Cap, then Acquiror shall elect, by written notice to Seller, to terminate
this Agreement as it relates to the ALSF Assets, in which event this Agreement
shall be of no further force or effect as provided in Article VII in respect
of the ALSF Assets.

            (c)   Notwithstanding anything to the contrary contained in the
form of Property Leases or the Agreement Regarding Leases, the parties hereto
agree that they will use their reasonable best efforts in accordance with
Section 5.05(c) to obtain consents and agreements, as applicable, from the
Existing Mortgage Lenders to the effect that (i) each Property Lease shall be
cross-defaulted with the other Property Leases under the Agreement Regarding
Leases, but to the extent such lenders do not agree to the same, the same

in connection with any offering of its securities, including the Private

another nationally recognized accounting firm reasonably acceptable to
Acquiror, to conduct an audit of, or if no audit is required, to perform the
procedures specified by the American Institute of Certified Public Accountants

Auditing Standards No. 71, Interim Financial Information, with respect to,
such required or advisable financial statements and, to the extent required by
the SEC or deemed advisable by the underwriters or initial purchasers, the
comparable period in the prior year and shall use reasonable commercial
efforts to facilitate any such audit or review. Seller will also reasonably
cooperate with Acquiror, in connection with any such audit or review and shall

any lease or becomes aware of any material default by a tenant under any

condition or agreement to be complied with or satisfied by it hereunder;
provided, that the delivery of any notice pursuant to this Section 5.13 shall
not limit or otherwise affect the remedies available to the party receiving
such notice. In addition, Seller will promptly inform Acquiror of the
happening of any event which would render any information supplied by Seller
specifically for inclusion in the Offering Memorandum or in any Registration
Statement incorrect in any material respect or would require the amendment of
the Offering Memorandum or any such Registration Statement.

            Section 5.14.  Further Action. From and after the First Closing
Date, Seller and Acquiror shall execute and deliver, or shall cause to be

            Section 8.02.  Indemnification by Acquiror. (a) Subject to
Sections 8.02(b), 8.03, 8.04, 8.06, 8.07 and 10.01, Acquiror shall indemnify,
defend and hold harmless Seller and their respective Affiliates (but not any
of the Companies) and Representatives (collectively, the "Seller Indemnified
Parties") against, and reimburse each Seller Indemnified Party for, all Losses
that such Seller Indemnified Party may at any time suffer or incur, or become
subject to, as a result of or in connection with:

                                      43
<PAGE>

                  (i)   any inaccuracy of any representation or warranty made
      by Acquiror in this Agreement or in the certificate referred to in
      Section 6.01(a)(iii);

                  (ii)  any failure by Acquiror to perform or comply with any
      of its covenants or agreements contained in this Agreement; and

                  (iii) any Third Party Claim to the extent relating to or
      arising out of any injury or death of any person or any property damage
      inflicted by any Representatives of Acquiror during any entry on or
      inspection of the Real Property Assets, including any invasive testing,
      performed by or on behalf of Acquiror pursuant to Section 2.08(c), but
      excluding any claims arising from (i) property damage arising from
      discovery of an existing condition during such inspection or testing and
      (ii) the presence of groundwater monitoring wells, which at Seller's
      option, Acquiror will either cause to be filled and abandoned in
      accordance with applicable Law or left intact and functional.

            (b)   Notwithstanding any other provision to the contrary,
Acquiror shall not be required to indemnify, defend or hold harmless any
Seller Indemnified Party against, or reimburse any Seller Indemnified Party
for, any Losses pursuant to Section 8.02(a)(i) (other than Losses arising out
of, resulting from, relating to or in connection with the inaccuracy or breach
of any representation or warranty made by Seller in Section 4.01, 4.02, or
4.08, as to which this Section 8.02(b) shall not apply) (i) with respect to
any claim (or series of related claims arising from the same underlying facts,
events or circumstances), unless such claim (or series of related claims
arising from the same underlying facts, events or circumstances) involves
Losses in excess of $25,000 and (ii) until the aggregate amount of all Losses
of the Seller Indemnified Parties exceeds $650,000, after which Acquiror shall
be liable for all Losses of the Seller Indemnified Parties, including such
$650,000. The cumulative aggregate indemnification obligation of the Acquiror
under Sections 8.02(a)(i) and 8.02(a)(iii) shall in no event exceed
$25,000,000 in the aggregate.

            (c)   For purposes of this Article VIII and for purposes of
determining whether Seller Indemnified Parties are entitled to indemnification
from Acquiror pursuant to Sections 8.02(a)(i) and 8.02(b), any breach of or
inaccuracy in any representation or warranty (other than any representation or
warranty contained in the last sentence of Section 4.07 as to which this
Section 8.02(c) shall not apply) of Acquiror shall be determined without
regard to any materiality qualifications set forth in such representation or
warranty, and all references to the terms "material," "materially,"
"materiality," or any similar terms shall be ignored for purposes of
determining whether such representation or warranty was true and correct when
made or deemed made.

            Section 8.03.  Notification of Third Party Claims. (a) A Person
that may be entitled to be indemnified under this Agreement (the "Indemnified
Party"), shall promptly notify the party or parties liable for such
indemnification (the "Indemnifying Party") in writing of any pending or
threatened claim or demand by a third party that the Indemnified Party has
determined has given or could reasonably give rise to a right of
indemnification under this Agreement (including a pending or threatened claim
or demand asserted by a third party against the Indemnified Party, such claim
being a "Third Party Claim"), describing in reasonable detail the facts and
circumstances with respect to the subject matter of such claim or demand;
provided,

                                      44
<PAGE>

however, that the failure to provide such notice shall not release the
Indemnifying Party from any of its obligations under this Article VIII except
to the extent the Indemnifying Party is actually prejudiced by such failure,
it being understood that (i) notices for claims in respect of an inaccuracy or
breach of a representation or warranty must be delivered prior to the
expiration of any applicable survival period specified in Section 10.01 for
such representation or warranty and (ii) notices for claims in respect of a
breach or failure to perform any covenant or agreement must be delivered prior
to the date that is six months after the last day of the effective period of
such covenant or agreement; provided, further, that if, prior to such
applicable date, a party hereto shall have notified the other party hereto in
writing of a claim for indemnification under this Article VIII (whether or not
formal legal action shall have been commenced based upon such claim), such
claim shall continue to be subject to indemnification in accordance with this
Article VIII notwithstanding the passing of such applicable date.

            (b)   Upon receipt of a notice of a claim for indemnity from an
Indemnified Party pursuant to Section 8.03(a), and subject to Section 8.03(e),
the Indemnifying Party may, by notice to the Indemnified Party delivered
within ten (10) Business Days of the receipt of notice of such claim, assume
the defense and control of any Third Party Claim but shall allow the
Indemnified Party a reasonable opportunity to participate in the defense of
such Third Party Claim with its own counsel and at its own expense. The
Indemnified Party may take any actions reasonably necessary to defend such
Third Party Claim prior to the time that it receives a notice from the
Indemnifying Party as contemplated by the preceding sentence. The Indemnifying
Party shall select counsel, contractors and consultants of recognized standing
and competence. To the extent the principal remedy sought in any Third Party
Claim is equitable relief, the Indemnifying Party shall consult with the
Indemnified Party as to the selection of counsel to defend such Third Party
Claim. Seller or Acquiror, as the case may be, shall, and shall cause each of
its Affiliates and Representatives to, cooperate in good faith with the
Indemnifying Party in the defense of any Third Party Claim. The Indemnifying
Party shall not be authorized to consent to a settlement of, or the entry of
any judgment arising from, any Third Party Claim, without the consent of any
Indemnified Party, provided that the Indemnified Party shall not withhold its
consent if such settlement or judgment involves solely the payment of money
without any finding or admission of any violation of Law or admission of any
wrongdoing and the Indemnifying Party shall (i) pay or cause to be paid all
amounts arising out of such settlement or judgment concurrently with the
effectiveness of such settlement and (ii) obtain, as a condition of any
settlement or judgment, a complete and unconditional release of each relevant
Indemnified Party from any and all liability in respect of such Third Party
Claim.

            (c)   If any Indemnifying Party receives a notice of a claim for
indemnity from an Indemnified Party pursuant to Section 8.03(a) that does not
involve a Third Party Claim, the Indemnifying Party shall notify the
Indemnified Party within thirty (30) days following its receipt of such
notice, whether the Indemnifying Party disputes its liability to the
Indemnified Party under this Article VIII. If the Indemnifying Party does not
so notify the Indemnified Party that it disputes such liability, the claim
specified by the Indemnified Party in such notice shall be conclusively deemed
to be a liability of the Indemnifying Party under this Article VIII, and the
Indemnifying Party shall pay, subject to the limitations set forth in Section
8.01(b), if applicable, the amount of such liability to the Indemnified Party
on demand or, in the case of any notice in which the amount of the claim (or
any portion of the claim) is estimated, on such later date when the amount of
such claim (or such portion of such claim) becomes finally determined. If the

                                      45
<PAGE>

Indemnifying Party has timely disputed its liability with respect to such
claim as provided above, the Indemnifying Party and the Indemnified Party
shall resolve such dispute in accordance with Section 10.11.

            (d)   If an Indemnified Party determines in good faith that it is
reasonably likely that a Third Party Claim would materially adversely affect
it other than as a result of monetary damages for which it would be entitled
to indemnification under this Agreement (including with respect to remediation
of any environmental matters), the Indemnified Party may, by notice to the
Indemnifying Party, assume the exclusive right to defend, compromise or settle
such Third Party Claim with its own counsel and at its own expense, provided,
however, that the Indemnifying Party will not be bound by any determination of
a Third Party Claim so defended or any compromise or settlement effected
without its written consent.

            (e)   Notwithstanding the foregoing, no Indemnifying Party shall
have any liability under this Article VIII for any Losses arising out of or
relating to any Third Party Claim that is settled or compromised by an
Indemnified Party without the consent of such Indemnifying Party (which
consent shall not be unreasonably withheld or delayed).

            Section 8.04.  Payment; Interest on Payment. In the event an
Action for indemnification under this Article VIII shall have been finally
determined, the amount of such final determination shall be paid to the
Indemnified Party, on demand in immediately available funds. An Action and the
liability for and amount of Losses, shall be deemed to be "finally determined"
for purposes of this Article VIII when the parties to such Action have so
determined by mutual agreement or, if disputed, when a final non-appealable
Governmental Order with respect thereto shall have been entered. Any amounts
not paid when due pursuant to this Article VIII shall bear interest from the
date thereof until the date paid at a rate equal to the rate publicly
announced from time to time by Citibank, N.A. as its prime or base rate.
Nothing in this Section 8.04 shall operate to bar an Indemnified Party from
seeking and (where appropriate) obtaining interest on any claim to the extent
ordered by a court adjudicating any Action brought by the Indemnified Party
against an Indemnifying Party.

            Section 8.05.  Exclusive Remedies. Each of Seller and Acquiror
acknowledges and agrees that, (a) prior to the First Closing or the Second
Closing, as applicable, other than in the case of actual fraud by the other,
the sole and exclusive remedy of such party for any inaccuracy of any
representation or warranty contained in this Agreement to be made at such
Closing shall be refusal to close the purchase and sale of Shares to be
acquired at such Closing and (b) following the First Closing or the Second
Closing, as applicable, other than in the case of actual fraud by the other or
any of its respective Affiliates or Representatives, the indemnification
provisions of this Article VIII and, with respect to Taxes, the Tax Matters
Agreement, shall be the sole and exclusive remedies for any inaccuracy of the
representations or warranties contained in this Agreement to be made at such
Closing and for any failure to perform or comply with any covenants or
agreements that, by their terms, were to have been performed or complied with
prior to such Closing. Notwithstanding anything in this Agreement to the
contrary, no Indemnifying Party shall have any liability under this Agreement
for Losses related to Taxes, which Losses shall be governed exclusively by the
Tax Matters Agreement.

                                      46
<PAGE>

            Section 8.06.  Additional Indemnification Provisions. (a) Seller
and Acquiror agree, for themselves and on behalf of their respective
Affiliates and Representatives, that, with respect to each indemnification
obligation in this Agreement, (i) all Losses shall be net of any Eligible
Insurance Proceeds (as set forth in subsection (e) below) and (ii) in no event
shall the Indemnifying Party have liability to the Indemnified Party for any
punitive, incidental, special, indirect or consequential damages, except to
the extent that the Indemnified Party pays punitive, incidental, special,
indirect or consequential damages to a third party in respect of a Third Party
Claim.

            (b)   Any amount payable by an Indemnifying Party pursuant to this
Article VIII shall be paid promptly and payment shall not be delayed pending
any determination of Eligible Insurance Proceeds or Retained Insurance
Proceeds. In any case where an Indemnified Party recovers from a third Person,
any amount in respect of any Loss for which such Indemnified Party has
actually been reimbursed by an Indemnifying Party pursuant to this Article
VIII (other than Retained Insurance Proceeds), such Indemnified Party shall
promptly pay over to the Indemnifying Party the amount so recovered (after
deducting therefrom the amount of expenses incurred by it in procuring such
recovery), but not in excess of the sum of (i) any amount previously paid by
the Indemnifying Party to or on behalf of the Indemnified Party in respect of
such Loss and (ii) any amount expended by the Indemnifying Party in pursuing
or defending any claim arising out of such matter.

            (c)   Seller and Acquiror shall treat any indemnification payment
made under this Agreement as an adjustment to the Final Purchase Price.

            (d)   All payments required to be made by an Indemnifying Party
under this Article VIII to any Indemnified Party shall be without set-off,
counterclaim or deduction of any kind.

            (e)   If any portion of Losses to be reimbursed by the
Indemnifying Party may be covered, in whole or in part, by third-party
insurance coverage (each, an "Insurance Policy"), the Indemnified Party shall
promptly give notice thereof to the Indemnifying Party (a "Notice of
Insurance"). If the Indemnifying Party so requests within 30 days after
receipt of a Notice of Insurance, the Indemnified Party shall use its
commercially reasonable efforts to collect the maximum amount of insurance
proceeds thereunder, in which event (i) all such proceeds actually received,
net of costs reasonably incurred by the Indemnified Party in seeking such
collection, shall be considered "Eligible Insurance Proceeds" and (ii) the
Indemnifying Party shall reimburse the Indemnified Party for all reasonable
costs incurred in connection with such collection and the amount of any
prospective or retroactive increase in premiums actually paid by the
Indemnified Party under the Insurance Policy (as such increased premiums are
incurred) directly related to the payment of Eligible Insurance Proceeds for
such Loss for three years following the next renewal of such Insurance Policy.
If the Indemnifying Party does not request that the Indemnified Party seek
coverage of any portion of such Loss under the Insurance Policy within 30 days
after receipt of a Notice of Insurance, (i) any proceeds that the Indemnified
Party may receive thereunder shall be considered "Retained Insurance Proceeds"
and (ii) the Indemnifying Party shall have no liability for any premium
increases thereunder relating to the collection of such Retained Insurance
Proceeds.

                                      47
<PAGE>

            (f)   If the indemnification provided for in Subsections
8.01(a)(i) and 8.02(a)(i) with respect to Losses relating to any inaccuracy of
any representation or warranty contained in Sections 3.26 and 4.09 is
unavailable or insufficient to hold harmless an Indemnified Party, then each
Indemnifying Party shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses (i) in such proportion as is
appropriate to reflect the relative benefits received by the Acquiror
Indemnified Parties, on the one hand, and the Seller Indemnified Parties, on
the other hand, from the sale of the shares of common stock of Acquiror in the
Private Placement and the use of the proceeds of the Private Placement or (ii)
if the allocation provided by clause (i) above is not permitted by applicable
Law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of
Acquiror Indemnified Parties, on the one hand, and the Seller Indemnified
Parties, on the other hand, in connection with the statements or omissions
which resulted in such Losses as well as any other relevant equitable
considerations. The relative fault shall be determined by reference to, among
other things, whether the untrue statement of a material fact or the omission
to state a material fact relates to information supplied by the Companies,
Seller or Acquiror and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such untrue statement or
omission.

            (g)   Notwithstanding anything to the contrary in this Article
VIII, to the extent that the Indemnified Party or an Affiliate realizes an
actual Tax benefit as a result of the event giving rise to the indemnity
payment hereunder (such as, by way of example but not limitation, a Tax
savings resulting from the payment of an indemnified amount that is deductible
by the Indemnified Party, in a case in which the indemnity payment itself does
not give rise to gross income for Tax purposes), the Indemnified Party shall
promptly rebate to the Indemnifying Party the amount of such Tax benefit.

            Section 8.07.  Mitigation of Losses. Each of the parties agrees to
take all reasonable steps to mitigate their respective Losses upon and after
becoming aware of any event or condition which would reasonably be expected to
give rise to any Losses that are indemnifiable hereunder. The Indemnifying
Party shall not be liable for Losses hereunder to the extent that such Losses
resulted solely from the Indemnified Party's failure to mitigate its Losses in
accordance with the preceding sentence.

            Section 8.08.  No Recourse to Controlling Persons of Seller. Each
of Acquiror and its respective existing and future Affiliates (collectively,
the "Releasing Parties") does hereby absolutely release and discharge,
effective as of each Closing, each of (i) FEBC-ALT Investors LLC, Emeritus
Corporation, NW Select LLC, their respective existing and future Affiliates
(other than Seller and its Subsidiaries) and their respective existing and
future officers and directors and (ii) the existing and future officers and
directors of Seller and its Subsidiaries (collectively, the "Releasees") from
any and all Losses which any of the Releasing Parties ever had or now has or
have or hereafter can, shall or may have, for, upon or by reason of any
matter, cause or thing whatsoever to the extent arising from, in connection
with, related to or as a result of (a) the matters addressed in this Agreement
with respect to such Closing and the other Transaction Agreements applicable
to such Closing, (b) the Private Placement and (c) any action or inaction of
any of the Releasees relating to or associated with the foregoing, in each
case, relating to any period from the beginning of the world to the end of
time, regardless of when brought; provided, however, such release and
discharge shall not release or discharge (i) any

                                      48
<PAGE>

Releasee from any Losses to the extent arising from, in connection with,
related to or as a result of any fraud, gross negligence or willful misconduct
by or on behalf such Releasee and (ii) the Selling Parties and their
respective successors and assigns from any of their respective obligations
under the Transaction Agreements, including the obligations of Seller under
this Article VIII.

                                  ARTICLE IX

                CASUALTY AND CONDEMNATION OF THE REAL PROPERTY

            Section 9.01.  Casualty. (a) If, on or prior to the Closing with
respect to a Real Property Asset, all or a "material part" (as defined below)
of such Real Property Asset shall be damaged or destroyed by fire or other
casualty (a "casualty event"), then, in any such event, Acquiror may, at its
option, either (i) elect to exclude such Real Property Asset from the
transactions contemplated by this Agreement, whereupon such Real Property
Asset shall be deemed to be an Excluded Real Property Asset, the Non-ALSF
Purchase Price and the ALSF Purchase Price, as applicable, shall be reduced by
the amount of net insurance proceeds actually received, or the amount of
insurance proceeds Seller and Acquiror reasonably estimate should be received
with respect to such Excluded Real Property Asset and Seller and Acquiror
shall be released of all obligations and liabilities of whatsoever nature in
connection with such Excluded Real Property Asset (other than Seller's
obligations to cause such asset to be transferred or distributed in accordance
with Section 5.08 and Seller's indemnification obligations hereunder in
respect of Excluded Assets), or (ii) proceed to close the transactions
contemplated by this Agreement, in which event all of the provisions of
Subsections 9.01(b)(i) and 9.01(b)(ii) below shall apply. If a Real Property
Asset is elected to be treated as an Excluded Real Property Asset pursuant to
clause (i) of this Section 9.01(a), then Seller shall use all reasonable
commercial efforts to cause such Excluded Real Property Asset to be
transferred from the applicable Company prior to the applicable Closing Date.
If Acquiror shall fail to make an election pursuant to this Section 9.01(a)
prior to the earlier of (A) thirty (30) days after Acquiror's receipt of
written notice of the applicable casualty event from Seller and (B) the
applicable Closing Date, then Acquiror shall be deemed to have made an
election pursuant to clause (ii) of this Section 9.01(a).

            (b)   If, on or prior to the Closing with respect to a Real
Property Asset, less than a material part of such Real Property Asset shall be
damaged or destroyed by a casualty event, Acquiror shall nevertheless
consummate the transactions contemplated herein pursuant to all the terms and
conditions of this Agreement (without any adjustment to the Non-ALSF Purchase
Price and the ALSF Purchase Price, as applicable, except as otherwise set
forth herein) with respect to such damaged Real Property Asset, subject to the
following: (i) Seller shall not (x) adjust and settle any insurance claims
with respect to such damaged Real Property Asset, or (y) enter into any
construction or other contract for the repair or restoration of such damaged
Real Property Asset, in each case, without Acquiror's prior written consent
(except no such consent shall be necessary to repair or restore any emergency
or hazardous condition at such damaged Real Property Asset), which consent
shall not be unreasonably withheld or delayed, and (ii) at the applicable
Closing, Seller shall (1) pay over to Acquiror the amount of any insurance
proceeds, to the extent collected by Seller in connection with such casualty
event, less the amount of the actual and reasonable unreimbursed expenses
incurred by Seller in connection

                                      49
<PAGE>

with collecting such proceeds and making any repairs to the applicable Real
Property Asset occasioned by such casualty event pursuant to any contract
(provided that such contract was reasonably approved by Acquiror as required
by this Section) and (2) assign to Acquiror in form reasonably satisfactory to
Acquiror all of Seller's right, title and interest in and to any insurance
proceeds that are uncollected at the time of the applicable Closing and that
may be paid in respect of such casualty event. Seller shall reasonably
cooperate with Acquiror in the collection of such proceeds, which obligation
shall survive the applicable Closing. To the extent that insurance proceeds
are paid over to Acquiror with respect to any damage to an Acquired Real
Property Asset pursuant to clause (ii) of this Section 9.01(b), Acquiror shall
use reasonable commercial efforts to cause such damage to be repaired;
provided, however, that the foregoing shall not require Acquiror to expend any
funds in excess of such insurance proceeds actually received by Acquiror in
respect of such damage pursuant to clause (ii) of this Section 9.01(b).

            For the purpose of this Section, the phrase a "material part" of a
Real Property Asset shall mean a portion of such Real Property Asset the cost
of repair or restoration of such portion is estimated by a reputable
contractor selected by Seller and reasonably satisfactory to Acquiror, to be
in excess of five percent (5%) of the Allocable Portion relating to such Real
Property Asset.

            (c)   If, prior to a Closing with respect to a Real Property
Asset, such Real Property Asset or any portion thereof shall be damaged or
destroyed by a casualty event, Seller shall promptly give Acquiror written
notice of such event, including information in reasonable detail regarding the
extent of the damage to such Real Property Asset or portion thereof.

            Section 9.02.  Condemnation Pending Closing. If, prior to a
Closing with respect to a Real Property Asset, condemnation or eminent domain
proceedings shall be commenced by any competent public authority against such
Real Property Asset or any portion thereof, Seller shall promptly give
Acquiror written notice thereof. After notice of the commencement of any such
proceedings (from Seller or otherwise) and in the event that the taking of
such Real Property Asset pursuant to such proceedings would constitute a
"Material Taking" (hereinafter defined), Acquiror shall have the right (i) to
accept title to such Real Property Asset subject to such proceedings,
whereupon any award payable to Seller shall be paid to Acquiror and Seller
shall deliver to Acquiror at the applicable Closing all assignments and other
documents reasonably requested by Acquiror to vest such award in Acquiror, or
(ii) elect to exclude such Real Property Asset from the transactions
contemplated by this Agreement, whereupon such Real Property Asset shall be
deemed to be an Excluded Real Property Asset, the Non-ALSF Purchase Price and
the ALSF Purchase Price, as applicable, shall be reduced by the amount of net
condemnation awards actually received, or the amount of condemnation awards
Seller and Acquiror reasonably estimate should be received with respect to
such Excluded Real Property Asset and Seller and Acquiror shall be released of
all obligations and liabilities of whatsoever nature in connection with such
Excluded Real Property Asset (other than Seller's obligations to cause such
asset to be transferred or distributed in accordance with Section 5.08 and
Seller's indemnification obligations hereunder in respect of Excluded Assets).
For the purposes of Section 9.01(a), a taking shall be deemed to be a
"Material Taking" with respect to any Real Property Asset if such taking
materially and adversely affects access to such Real Property Asset, or leaves
a remaining balance of such Real Property Asset which may not be economically
operated for the purpose for which the Real Property Asset was operated prior
to

                                      50
<PAGE>

such taking, or if in the reasonable estimation of an appraiser selected by
Seller, subject to Acquiror's reasonable approval, the taking would result in
a claim for condemnation proceeds equal to or in excess of five percent (5%)
of the Allocable Portion of the Non-ALSF Purchase Price and the ALSF Purchase
Price, as applicable. If a Real Property Asset is elected to be treated as an
Excluded Real Property Asset pursuant to clause (ii) of Section 9.01(a), then
Seller shall use all reasonable commercial efforts to cause such Excluded Real
Property Asset to be transferred from the Company prior to the applicable
Closing Date. If Acquiror shall fail to make an election pursuant to this
Section 9.02 prior to the earlier of (A) thirty (30) days after Acquiror's
receipt of written notice of the applicable proceedings from Seller and (B)
the applicable Closing Date or if a taking of any Real Property Asset in any
proceedings would not constitute a Material Taking, then Acquiror shall be
deemed to have made an election pursuant to clause (i) of this Section 9.02.

                                   ARTICLE X

                              GENERAL PROVISIONS

            Section 10.01.  Survival. Notwithstanding the First Closing or the
ALSF Closing hereunder, (x) the representations and warranties of Seller and
Acquiror contained in or made pursuant to this Agreement or in any certificate
furnished pursuant to this Agreement shall survive in full force and effect
until the date that is eighteen (18) months after the applicable Closing Date
on which such representations and warranties were made, at which time such
representations and warranties shall terminate and expire (and no claims shall
be made for indemnification under Sections 8.01 or 8.02 after such termination
and expiration); provided, however, that (i) the representations and
warranties made in the sixth sentence of Section 3.03 shall survive the
applicable Closing indefinitely, (ii) the representations and warranties made
in Sections 3.01, 3.02, 3.03 (other than the sixth sentence of Section 3.03),
3.13, 3.19, 3.20, 4.01 and 4.02 shall survive until the expiration of the
applicable statute of limitations and (y) the covenants and agreements of
Seller and Acquiror contained in or made pursuant to this Agreement shall
survive for the period provided in such covenants and agreements, if any, or
until fully performed.

            Section 10.02.  Expenses; Transaction Costs. Except as may be
otherwise specified in this Agreement (including the $1,000,000 limitations on
certain Transaction Costs as provided in Section 5.05(c)), all Transaction
Costs shall be paid by Seller, except that all cost and expenses incurred by
the Companies and payable to a third party (x) in connection with obtaining
any third-party consent or approval required to be obtained as a condition to
any party's obligations under this Agreement or (y) consisting of legal,
accounting, consulting, actuarial or other professional fees or disbursements,
shall be reimbursed by Seller to the Companies, as applicable, prior to the
applicable Closing. No later than three (3) Business Days prior to the
applicable Closing Date, Seller shall prepare and deliver to Acquiror a
written notice setting forth the amount of Transaction Costs to be included in
the Non-ALSF Purchase Price and the ALSF Purchase Price, as applicable,
pursuant to Section 2.03, which amount shall increase the Allocable Portions,
and be added to the Lease Basis (as defined in the form of Property Leases)

public announcements in respect of this Agreement or the transactions
contemplated by this Agreement without the prior consent of the other parties,

unreasonably withheld. Notwithstanding the foregoing, Seller acknowledges that

Sections 5.04(a), 5.11 and 5.12, may disclose the transactions contemplated

Law or as a matter of public policy, all other conditions and provisions of
this Agreement shall nevertheless remain in full force and effect so long as
the economic or legal substance of the transactions contemplated by this
Agreement is not affected in any manner materially adverse to any party. Upon
such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties to this Agreement shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in a mutually acceptable manner in

                                      53
<PAGE>

order that the transactions contemplated by this Agreement be consummated as
originally contemplated to the greatest extent possible.

            Section 10.06.  Entire Agreement. Except as otherwise expressly
provided in the this Agreement, or as otherwise expressly agreed in writing by

(but not its obligations) hereunder to one or more Affiliates of Acquiror
designated in a written notice delivered by Acquiror to Seller at least three
(3) Business Days prior to the applicable Closing; provided, however, that no
such assignment by Acquiror shall (x) release Acquiror from any liability or
obligation under this Agreement or (y) be permissible if it could reasonably
be expected to delay, hinder or jeopardize the consummation of any
transactions contemplated by this Agreement. This Agreement shall be binding
upon, shall inure to the benefit of, and shall be enforceable by Seller and
Acquiror and their permitted successors and assigns.

            Section 10.08.  No Third-Party Beneficiaries. Except as provided
in Article VIII with respect to Seller Indemnified Parties, Acquiror
Indemnified Parties and the Releasees, this Agreement is for the sole benefit
of the parties to this Agreement and their successors and permitted assigns
and nothing in this Agreement, express or implied, is intended to or shall
confer upon any other Person any legal or equitable right, benefit or remedy
of any nature whatsoever under or by reason of this Agreement.

            Section 10.09.  Amendment. No provision of this Agreement may be
amended, waived or modified except by a written instrument signed by all the
parties to such agreement.

            Section 10.10.  Disclosure Schedules. Any disclosure with respect
to a Schedule shall be deemed to be disclosed for other Sections of this
Agreement to the extent that such disclosure sets forth facts in sufficient
detail so that the relevance of such disclosure would be reasonably apparent
to a reader of such disclosure; provided, however, that no representation or
warranty contained in this Agreement shall be deemed to be modified or
qualified by any disclosure set forth in the Schedules, if, by its terms, such
representation or qualification is incapable of being modified or qualified by
any disclosure set forth in the Schedules. No reference to or disclosure of
any item or other matter in any Section or Schedule of this Agreement shall be
construed as an admission or indication that such item or other matter is
material or that such item or other matter is required to be referred to or
disclosed in this Agreement.

            Section 10.11.  Governing Law; Submission to Jurisdiction;
Waivers. THIS AGREEMENT AND EACH OTHER TRANSACTION AGREEMENT SHALL BE GOVERNED

shall be entitled to specific performance of the terms hereof and any other
similar equitable remedy to which Acquiror may be entitled.
