                              STIPULATION AND ORDER
                              ---------------------

into as of the date set forth below by and among the above-captioned debtors and
debtors-in-possession (collectively, the "Debtors"), and Ventas, Inc., on behalf
of itself and each of Ventas Realty, Limited Partnership and Ventas LP Realty,
L.L.C. (collectively, "Ventas," and, together with the Debtors, the "Parties").

          WHEREAS, on May 1, 1998, Ventas, Inc. effected a corporate
reorganization (the "1998 Spin Off") pursuant to which Ventas, Inc. (then known
as Vencor, Inc.) was separated into two publicly held corporations. A new
corporation, subsequently renamed Vencor, Inc., was formed to operate the
hospital, nursing center and ancillary services businesses. The continuing
corporation, now known as Ventas, Inc., continued to hold title to substantially
all of the real property; and

          WHEREAS, the 1998 Spin Off was effected through an Agreement and Plan
of Reorganization by and between Vencor, Inc. (now Ventas, Inc.) and Vencor
Healthcare, Inc. (now Vencor, Inc.)
<PAGE>

dated as of April 30, 1998 and related agreements (the "Reorganization
Agreements"); and

          WHEREAS, the Debtors, Ventas, Inc. and Ventas Realty, Limited
Partnership are parties to a stipulation, dated September 13, 1999 (the "Rent
and Reorganization Stip"), governing, among other things, the payment of rent
and performance under the Reorganization Agreements by the Debtors during the
pendency of the chapter 11 cases and the period in which the Rent and
Reorganization Stip is in force and effect; and

          WHEREAS, the Rent and Reorganization Stip remains in full force and
effect; and

          WHEREAS, on September 15, 1999, Ventas, Inc. filed its 1998
consolidated federal income tax return (the "Consolidated Return"); and

          WHEREAS, pursuant to the Consolidated Return, on February 3, 2000,
Ventas received a tax refund in the total amount of $26,609,865.60 (comprised of
$25,349,528.00 in tax and $1,260,337.60 in interest) (the "Federal Refund
Proceeds"); and

          WHEREAS, the Tax Refunds1 received by Ventas prior to the date hereof
are listed on Exhibit A hereto (such Tax Refunds

--------

1    For purposes of this Stipulation and Order, "Tax Refunds" shall mean all
     refunds received (including those endorsed over by one Party to the other
     Party in which case such refund shall be deemed received by the Party to
     which the refund was endorsed over) on or after September 13, 1999, in
     respect of federal, state or local property, franchise, income, excise,
     sales and use, and similar business taxes previously paid for tax years
     ending prior to or including April 30, 1998; provided, however, that Tax
     Refunds shall not include the refund of over payments or estimated taxes to
     the extent such over payments or estimated taxes were paid by a Party after
     April 30, 1998 and subsequently refunded by the applicable tax authority.

listed on Exhibit A (which includes the Federal Refund Proceeds) and any Tax
Refunds received by Ventas on or after the date hereof, together with the
Interest Amount2 thereon, are collectively referred to herein as the "Ventas
Refund Proceeds"); and

          WHEREAS, simultaneously with the execution hereof, Ventas has
delivered to the Debtors a list of the Pre-Spin Refunds3 received by Ventas; and

          WHEREAS, the Tax Refunds received by the Debtors prior to the date
hereof are listed on Exhibit B hereof (such Tax Refunds listed on Exhibit B and
the Tax Refunds received by the Debtors on or after the date hereof, together
with the Interest Amount thereon, are collectively referred to herein as the
"Vencor Refund Proceeds" and together with the Ventas Refund Proceeds, are
referred to as the "Refund Proceeds"); and

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

2    For purposes of this Stipulation and Order, "Interest Amount" shall mean,
     with respect to a Tax Refund, interest on the Tax Refund computed at the
     lesser of (a) the actual interest earned, and (b) 3% annual interest, for
     the period during which such Tax Refund is deposited in a Ventas Account or
     Vencor Account (as such terms are defined below) as the case may be.

3    For purposes of this Stipulation and Order, "Pre-Spin Refunds" shall mean
     all refunds received (including those endorsed over by one Party to the
     other Party in which case such refund shall be deemed received by the Party
     to which the refund was endorsed over) on or after January 1, 1999, but
     prior to September 13, 1999, in respect of federal, state or local
     property, franchise, income, excise, sales and use, and similar business
     taxes previously paid for tax years ending prior to or including April 30,
     1998; provided, however, that Pre-Spin Refunds shall not include the refund
     of over payments or estimated taxes to the extent such over payments or
     estimated taxes were paid by a Party after April 30, 1998 and subsequently
     refunded by the applicable tax authority.

                                      -3-
<PAGE>

          WHEREAS, simultaneously with the execution hereof, the Debtors have
delivered to Ventas a list of the Pre-Spin Refunds received by the Debtors; and

          WHEREAS, Ventas asserts that it is entitled to the Refund Proceeds on
various legal grounds, including, without limitation, pursuant to the express
terms of the Reorganization Agreements and, alternatively, that any claim of the
Debtors to the Refund Proceeds is subject to, without limitation, recoupment,
setoff and other defenses and claims of or by Ventas under the Reorganization
Agreements and the Rent and Reorganization Stip; and

          WHEREAS, the Debtors assert that they are entitled to the Refund
Proceeds on various legal grounds; and

          WHEREAS, each Party seeks to protect the Refund Proceeds pending
resolution of the rights of the Parties.

          NOW, THEREFORE, IT IS STIPULATED AND AGREED by and between the Parties
that:

          1.   In the event that the Bankruptcy Court fails to approve this
Stipulation and Order on or before May 31, 2000, or such approval is
subsequently modified, rescinded or stayed, this Stipulation and Order shall
automatically terminate and be of no force and effect. Pending approval of the
Bankruptcy Court as referenced in the preceding sentence, either Party may
terminate this Stipulation and Order by providing one business day's notice
(which may be by facsimile transmission) to the other Party.

          2.   The Ventas Refund Proceeds shall be deposited in one or more
segregated interest-bearing accounts at a federally insured depository
institution in the name of Ventas, Inc. or

                                      -4-
<PAGE>

Ventas Realty, Limited Partnership; provided, however, that all or a portion of
the Ventas Refund Proceeds may be invested in a commercially reasonable manner
so long as any investment of the Ventas Refund Proceeds remains segregated from
the other investments of Ventas, Inc. and Ventas Realty, Limited Partnership
(any such depository or investment account or other investment of Ventas Refund
Proceeds, a "Ventas Account"). Ventas shall provide the Debtors with notice
within two business days after (a) the opening of a Ventas Account (which notice
shall specify the location of the Ventas Account, including the account number);
and/or (b) the receipt of a Tax Refund (which notice shall specify the amount of
the Tax Refund, the Ventas Account into which such Ventas Refund Proceeds have
been deposited and the facts and circumstances giving rise to the Tax Refund and
include a copy of the refund claim). Upon request of the Debtors, Ventas shall
promptly (which in no case shall exceed two business days) provide the Debtors
with the monthly written account statements received by Ventas for each of the
Ventas Accounts, it being understood that Ventas may redact any information that
is unrelated to the Ventas Accounts. If all or any portion of the Ventas Refund
Proceeds are transferred between Ventas Accounts, Ventas shall promptly provide
written notice (which in no case shall exceed two business days) to the Debtors
of the Ventas Account into which the Ventas Refund Proceeds (or portion thereof)
have been transferred. This Stipulation and Order and the terms and conditions
hereof, including the establishment and maintenance of a Ventas Account, shall
not be (a) deemed an admission by any Party in respect of any matter

                                      -5-
<PAGE>

whatsoever; (b) probative of the Parties' respective rights, if any, to the
Refund Proceeds or any portion thereof, including any principal or interest
component thereof; or (c) otherwise affect or impair any rights of the Parties.

          3.   The Vencor Refund Proceeds shall be deposited in one or more
segregated interest-bearing accounts at a federally insured depository
institution in the name of Vencor, Inc.; provided, however, that all or a
portion of the Vencor Refund Proceeds may be invested in a commercially
reasonable manner so long as investment of the Vencor Refund Proceeds remains
segregated from other investments of Vencor, Inc. and any of the other Debtors
(any such depository or investment account or other investment of Vencor Refund
Proceeds, a "Vencor Account"). The Debtors shall provide Ventas with notice
within two business days after (a) the opening of a Vencor Account (which notice
shall specify the location of the Vencor Account, including the account number);
and (b) the receipt of a Tax Refund (which notice shall specify the amount of
the Tax Refund, the Vencor Account into which such Vencor Refund Proceeds have
been deposited and the facts and circumstances giving rise to the Tax Refund and
include a copy of the refund claim). Upon request of Ventas, the Debtors shall
promptly (which in no case shall exceed two business days) provide Ventas with
the monthly written account statements received by the Debtors for each of the
Vencor Accounts, it being understood that the Debtors may redact any information
that is unrelated to the Vencor Accounts. If all or any portion of the Vencor
Refund Proceeds are transferred between Vencor Accounts, the Debtors shall
promptly provide written notice (which in no

                                      -6-
<PAGE>

case shall exceed two business days) to Ventas of the Vencor Account into which
the Vencor Refund Proceeds (or portion thereof) have been transferred. This
Stipulation and Order and the terms and conditions hereof, including the
establishment and maintenance of a Vencor Account, shall not be (a) deemed an
admission by any Party in respect of any matter whatsoever; (b) probative of the
Parties' respective rights, if any, to the Refund Proceeds or any portion
thereof, including any principal or interest component thereof; or (c) otherwise
affect or impair any rights of the Parties.

          4.   Ventas or the Debtors, as the case may be, shall provide notice
(a "Notice") to the parties listed on Exhibit C by facsimile (receipt confirmed)
and overnight mail at least five (5) business days prior to withdrawing the
Refund Proceeds or any portion thereof (the "Waiting Period") from a Ventas
Account (in the case of Ventas) or a Vencor Account (in the case of the
Debtors); provided, however, that the foregoing shall not apply to the extent
that the Refund Proceeds are being transferred from one Ventas Account to
another Ventas Account or from one Vencor Account to another Vencor Account, in
which case paragraphs 2 and 3 hereof respectively shall govern; provided,
further, that the foregoing shall apply as modified below in the case of a Tax
Payment Withdrawal. A "Tax Payment Withdrawal" is a withdrawal by Ventas from a
Ventas Account or by the Debtors from a Vencor Account if such withdrawal is
made for the sole purpose of applying such amounts in payment of federal, state
or local property, franchise, income, excise, sales and use, withholding, or
similar tax liability, including interest and penalties, if

                                      -7-
<PAGE>

any, for tax years ending prior to or including April 30, 1998, up to the amount
of the Refund Proceeds then contained in the applicable Ventas or Vencor
Account. Ventas shall be permitted to make Tax Payment Withdrawals from Ventas
Accounts and the Debtors shall be permitted to make Tax Payment Withdrawals from
Vencor Accounts upon such withdrawing Party's delivery of Notice regarding any
such withdrawal, which shall include a copy of any applicable notice or other
related documents and any return or other form filed with the taxing authority
in respect of the payment made using the Tax Payment Withdrawal. Upon the expiry
of any applicable Waiting Period, the Party providing the Notice shall have no
further obligations pursuant to this Stipulation and Order respecting the use,
maintenance, deposit or investment of any portion of the Refund Proceeds that is
the subject of such Notice.

          5.   The Parties reserve all rights with respect to their claims,
defenses and contentions regarding the Refund Proceeds except as expressly
provided in paragraph 6 hereof.

          6.   Nothing in this Stipulation and Order shall constitute admissions
by any of the Parties or shall be used in any subsequent litigation by the
Parties or any other person or entity other than for the purpose of enforcement
of this Stipulation and Order.

          7.   Without limiting the provisions of paragraph 4 hereof, any
notices to be sent in accordance with this Stipulation and Order will not be
effective unless sent to the following:

     in the software delivered by Vyyo (as contained in or delivered in
     conjunction with the Products) and all connected, modified, improved or
     enhanced versions or derivatives thereof delivered by Vyyo, and the
     relevant documentation delivered by Vyyo, is owned by and will remain
     vested in Vyyo.  Title and all intellectual property rights in or relating
     to the software delivered by Vyyo (as contained in or delivered in
     conjunction with the Products) and the Products documentation delivered by

             notice to Vyyo invoke a worldwide license to use Vyyo's object code
             including specifically, software object code and object code for
             configuring programmable devices and associated drawings of the hub
             for the product which is being sold as a standard product
             commercially at that time by Vyyo and any other items reasonably
             necessary to allow ADC to manufacture which shall not include
             technical
<PAGE>
                                               CONFIDENTIAL TREATEMENT REQUESTED

             assistance or documentation used by Vyyo beyond Vyyo's english
             translation of documentation used by Vyyo for its own production
             ("Vyyo Deliverables") to develop and manufacture, use, sell, have
             sold and import solely wireless hubs for the MMDS market. If ADC so
             elects, then within ten (10) business days after its receipt of
             such notice Vyyo will deliver to ADC Vyyo Deliverables. In return
             for such license, ADC will pay to Vyyo an amount equal to the
             Royalty Percentage (as set forth in Exhibit A) attached hereto of
             the total sales price for any product sold by ADC with
             functionality similar to that of the Vyyo Deliverables whether or
             not the Vyyo Deliverables are used. The total sales price shall not
             be less than a commercially reasonable price for such product. This
             license is "as is" "where is" with no warranty whatsoever and is
             for the Vyyo Deliverables as in effect as of the date of the
             invocation of this license. Vyyo will provide to ADC generally
             available updates to the standard Vyyo Deliverables (not any that
             are customized for third parties) to the extent that Vyyo owns the
             intellectual property or can through its best efforts attain the
             right to deliver such third party intellectual property without
             additional expense to Vyyo. The updates shall only be for wireless
             MMDS hubs with the same platform as in the Vyyo Deliverables, such
             updates shall incorporate (A) corrections of any substantial
             defects, (B) fixes of any minor bugs, and (C) enhancements and new
             releases to the Vyyo Deliverables that are generally made available
             in the market by Vyyo (collectively "Vyyo Enhancements"). ADC
             agrees not to, and its license from Vyyo shall be interpreted to
             prohibit the, manufacture products using the Vyyo Deliverables
             until six (6) months after the date upon which ADC gives to Vyyo
             notice that it intends to manufacture such products. Vyyo's
             obligation to deliver to ADC the Vyyo Enhancements shall continue
             until the first to occur of (A) the end of the initial term of the
             Agreement without extension, (B) the maintenance fee as described
             below is not timely paid to Vyyo after written notice is given to
             ADC, or (C) any calendar quarter in which ADC fails to purchase at
             least *** of all of its wireless MMDS CPEs from Vyyo. To the extent
             that ADC claims that Vyyo's CPEs are not competitive in price,
             performance or delivery capability the parties agree to meet in
             good faith to resolve those issues. If Vyyo after a reasonable
             period of time is unable to become competitive in those areas or
             build additional requested functionality into the CPE, ADC shall be
             entitled to not include in the numerator or denominator of the
             applicable equation such CPEs sold by ADC which are not purchased
             from Vyyo until Vyyo becomes competitive. In the event that Vyyo
             sells directly CPEs to accounts which have been and are currently
             purchasing the headends from ADC pursuant to ADC's manufacturing
             rights of this Section, those CPEs shall be included in both the
             numerator and denominator of the applicable equation. ADC and Vyyo
             agree in general to discuss the allocation of maintenance fees
             charged to customers of ADC for those Vyyo products resold by ADC.
             For products manufactured by ADC hereunder, ADC shall use its
             commercially reasonable efforts to split the maintenance fee into
             two components. One will be for software maintenance and Vyyo shall
             be entitled to receive *** of said amount. If the maintenance fee
             cannot be reasonably separated, then Vyyo shall receive *** of the
             entire maintenance fee charged by

                                                                       TREATMENT
                                                                       REQUESTED

             ADC to its customers using products manufactured by ADC pursuant to
             this Section. The maintenance fees to be charged by Vyyo to ADC
             shall be paid to Vyyo within 30 days after ADC assesses such fees
             to its customers. ADC shall report to Vyyo all of its subject sales
             within 15 days after the end of each calendar month and Vyyo shall
             have a right to audit applicable books and records of ADC in
             connection with the royalty and maintenance fees. The cost of the
             audit shall be borne by Vyyo unless the audit shows an underpayment
             of more than 2.5% of the amounts actually owed, in which case the
             full cost of the audit shall be borne by ADC.

9.   Section 14(d).  Section 14(d) of the Agreement is deleted in its entirety
     -------------
     and replaced by the following:

          d.  Notwithstanding the foregoing, Vyyo will have no liability or
     obligation, and Buyer shall defend and indemnify Vyyo to the same extent as
     Vyyo's defense and indemnity of Buyer in subsection 14(b) above (and not
     including the limitations in subsection 14(c)), with respect to any
     proceeding or action arising out of (i) modification of the Product other
     than by Vyyo or its agents, (ii) combination of the Product with any other
     item (including without limitation any claim for contributory infringement
     or inducing infringement) if such claim would not have occurred but for
     such combination, or (iii) compliance with Buyer's specifications or
     design.

10.  Pricing.  Exhibit A is deleted in its entirety and replaced by the attached
     -------
Exhibit A.  Any preferred pricing to ADC, except as stated in Section 3 (d) of
the Agreement and Section II, Paragraphs A, B, C.1-C.3 of Exhibit A hereto,
shall terminate on the first to occur of (i) the date that ADC actually ships a
product to any customer pursuant to its manufacturing rights under Addendum
Section 7 (above), or (ii) July 14, 2002.

11.  ADC Requested Product Changes.  Section 9 of Exhibit C is deleted in its
     -----------------------------
entirety and replaced by the following:

     9.   Design Changes.

     Upon request by ADC, Vyyo will use commercially reasonable efforts to
     develop specific changes and additions, including without limitation an ADC
     custom product router card (collectively, "Modifications") and shall agree
     to negotiate in good faith with ADC for other requests.  ADC will provide a
     Requirements Specification describing the functionality for the
     Modifications as well as the documentation and other deliverables expected.
     Vyyo will provide a timely estimate of costs, including travel time, with
     the engineering fee to be billed at a rate of ******** per man-year to
     perform the development of the applicable Modifications.  Upon ADC's
     approval of the total price estimate for the effort, Vyyo will perform the
     effort and ADC will compensate Vyyo as set forth in the estimate. Unless
     the parties agree otherwise in writing, ADC will own all intellectual
     property rights (including, without limitation, all patent, copyright,
     trade
<PAGE>
                                                CONFIDENTIAL TREATMENT REQUESTED

     secrets) in and to any Modifications.  In addition, ADC will own
     manufacturing rights to any hardware associated with any Modifications that
     results from the effort, but not as to any underlying intellectual property
     of Vyyo.  ADC may request Vyyo to estimate the cost to manufacture any
     hardware associated with the Modifications and, upon ADC's written
     approval, Vyyo will use commercially reasonable efforts to manufacture a
     timely, high quality product that includes the Modifications and make such
     product available to ADC for purchase on commercially reasonable terms.
     All software associated with the Modifications will be included in the WMTS
     software load delivered with the WMTS from Vyyo and shall remain the
     intellectual property of Vyyo.  Vyyo shall have a perpetual, royalty-free,
     worldwide license back for all intellectual property rights including,
     without limitation, the Modifications to manufacture a product using the
     Modifications for sale to others, except as otherwise agreed in good faith
     between the parties for any Modifications that include intellectual
     property rights of ADC.  Should ADC believe that the Modifications shall
     include intellectual property rights of ADC, Vyyo and ADC shall negotiate

II.  PRICES
     ------

     A.  Unless otherwise agreed in writing, all Products supplied to Buyer will
         be at the prices set out in this Exhibit.  For any Head-End Product (as
         defined in the following subsection) for ***********, the price will be
         ************ (1) the price in effect as of the effective date of this
         Agreement or (2) the price determined in accordance with the following
         subsection B.

     B.  Pricing
         -------

         Prices for Products covered by this Agreement will be based on market
         prices (the "Market Prices") to be established by good faith
         negotiations between the Parties in accordance with Section C.2. of
         this Exhibit. The initial Market Prices for currently available
         Products are subject to negotiation between the parties. A list of the
         currently available Products follows:

                                  Product
----------------------------------------------------------------------------
         P2001-1.5W Network Ctlr Package w/SNMP

         P200-EX Speed-Demon Wireless Modem
         P200-SH SOHO Speed-Demon Wireless Modem

       The price for a Product to be sold hereunder will be the
       **************************** (the "*******************"). The
       ******************* will depend whether the Product is intended for use
       on customer premises (a "CPE Product") or at the head-end of a system (a
       "Head-End Product"). Except as otherwise agreed to by the parties, the
       ******************** for Preferred Vendor Accounts will be determined as
       follows:

                             Type of Equipment
       -------------------------------------------------------------------------
               CPE Product                            Head-End Product
       --------------------------------     ------------------------------
                   ***                                       ***

       The ******************** for others will be determined as follows:

                             Type of Equipment
----------------------------------------------------------------------------
               CPE Product                            Head-End Product

                                                                       TREATMENT
                                                                       REQUESTED

     C.  General
         -------

          1.   All prices will be *** Vyyo's ***************** (per Section 4.a.
               of the Agreement) unless mutually agreed upon otherwise in an
               applicable negotiated Annex. Although Vyyo may publish suggested
               wholesale or retail prices, these are suggestions only and Buyer
               will be entirely free to determine the actual prices and license
               fees at which the Products will be sold or licensed to its
               Customers.

          2.   Market Prices will be valid until superseded by new Market
               Prices. Market Prices will be subject to
               ************************* on a quarterly basis, in February, May,
               August and November, beginning in July 2000. Key considerations
               for the establishment of Market Prices will be (1) those prices
               charged by Vyyo and ADC to their respective customers for
               comparable standard products, and (2) competitive pricing in the
               market. It is acknowledged by Vyyo that, in general, ADC will
               endeavor to sell above the Market Price. Re-negotiated Market
               Prices will be reduced to written Annexes, which, when signed and
               dated by both parties, will serve as an amendment to this
               Agreement, and will supersede any earlier Market Price
               determinations.

          3.   All prices are subject to the provisions of Section 3.d. of the
               Agreement.

          4.   With respect to sales of WTMS Products (which bear the Vyyo
               brand), and not CPE Products, by Vyyo directly to
               **************************, between the Effective Date hereof and
               the first to occur of (a) *************, or (b) the date upon
               which ADC first sells product under its manufacturing rights set
               forth in Addendum Section 7 of this Addendum to any one of
               **************************, Vyyo will pay to ADC a commission
               equal to *** of the Net Invoiced Amounts for such Products in
               accordance with the terms of Section 6.d of the Agreement.

The parties agree that obtaining accurate information regarding sales prices
charged by the other party will be vital to the calculation under subsection 2,
above.  The parties therefore agree that sales by each party may be audited by
the other party in accordance with reasonable procedures to be agreed upon by
the parties at the time of audit with the audit being conducted subject to the
confidentiality provisions of the Agreement.

III. DEFINITIONS.   For purposes of this Addendum, the
     --------------
******************************* shall be ***, the Royalty Percentage shall be
***, and the Preferred Vendor Accounts shall be
**********************************************.
