                         AGREEMENT OF SALE AND PURCHASE

         THIS AGREEMENT OF SALE AND PURCHASE (the "AGREEMENT") is made and
entered into this 15th day of March, 2005 by and between SWISSAIR, SWISS AIR
TRANSPORT CO. LTD. IN DEBT RESTRUCTURING LIQUIDATION, a corporation organized
under the laws of Switzerland ("SELLER"), and OSI PHARMACEUTICALS INC., a
Delaware corporation ("PURCHASER").

                                   WITNESSETH:

         WHEREAS, Seller is the owner of that certain real property located at
41 Pinelawn Road, Melville, New York, consisting of the land more particularly
described in Exhibit A attached hereto and made a part hereof (the "LAND"),
together with all improvements, rights, privileges and easements appurtenant to
or used in connection with the ownership and operation of said Land, including,
without limitation: (i) the buildings, structures and improvements, together
with all and singular tenements, hereditaments and appurtenances thereunto
belonging or in otherwise appertaining, now erected or situated on the Land
(collectively, the "BUILDING"); (ii) the fixtures, equipment, machinery and
other tangible personal property located at and used in connection with the
operation of the Building, limited to the property of Seller listed on Schedule
1 attached hereto (collectively, the "BUILDING EQUIPMENT"); (iii) all of
Seller's right, title and interest in title to any land lying in the bed of any
street, road or avenue, opened or proposed, in front of or adjoining the Land,
to the centerline thereof, and any strips and gores adjacent to the Land, and
all right, title and interest of Seller in and to any award made or to be made
in lieu thereof and in and to any unpaid award for damage to the Land and
Building by reason of change of grade of any street; (iv) all Permits, if any
and to the extent assignable (collectively, the "ASSIGNABLE PERMITS"); (v) all
of Seller's right, title and interest in and to any Contracts that are assigned
to, and assumed by, Purchaser; (vi) to the extent assignable or transferable,
all warranties, guaranties, other intangible rights, titles, interests,
privileges and appurtenances related exclusively to, or used exclusively in
connection with, the ownership, use or operation of the Land or the Building, if
any; and (vii) any Plans in the possession of Seller (all of the above
collectively, the "PROPERTY"). Certain of the terms used in this Agreement with
initial capital letters are defined in Exhibit B attached hereto;

         WHEREAS, Purchaser desires to purchase the Property subject to all the
terms and conditions hereinafter set forth and Seller is agreeable to such sale
subject to all the terms and conditions hereinafter set forth;

         WHEREAS, pursuant to petitions filed on October 3, 2001 and October 5,
2001 with the District Courts of Bulach (Bezirksgericht Bulach) and Zurich
(Bezirksgericht Zurich) (collectively, the "SWISS COURT"), Seller and certain
other parties asked the Swiss Court for a temporary debt moratorium. On May 22,
2003, the Swiss Court in Bulach approved a debt restructuring plan for Seller
and under such plan, Karl Wuthrich was appointed as the official Liquidator for
Seller (the "LIQUIDATOR");

<PAGE>

         WHEREAS, on October 8, 2001, a petition for relief under Section 304 of
the United States Bankruptcy Code was filed on behalf of Seller in the United
States Bankruptcy Court for the Southern District of New York (the "COURT")
thereby commencing a case ancillary to a foreign proceeding (the "ANCILLARY
BANKRUPTCY CASE"), which is currently pending in the Court under Case No.
01-42536 (SMB);

         WHEREAS, the Court entered a preliminary injunction order (the
"PRELIMINARY INJUNCTION ORDER") in the Ancillary Bankruptcy Case which, among
other things, provides that all persons and entities are enjoined from
transferring or disposing of any legal or equitable interests of Seller in
property in the United States and further provides that Seller must provide
advance written notice to certain persons or entities of certain transfers,
sales or other dispositions of Seller's property; and

         WHEREAS, Seller intends to follow the procedure set forth in the
Preliminary Injunction Order to provide notice of the transactions contemplated
hereby (the "SALE NOTICE") and, if any objections shall have been made in
response to the Sale Notice, or if Seller otherwise determines that it is
necessary or appropriate, to seek an order of the Court in the Ancillary
Bankruptcy Case which authorizes or approves the transactions contemplated
hereby or declares that no such authorization or approval from the Court is
necessary (the "APPROVAL ORDER").

         NOW, THEREFORE, in consideration of the respective undertakings of the
parties hereafter set forth and for other good and valuable consideration, the
receipt and sufficiency of which is hereby acknowledged, the parties intending
to be legally bound, hereby agree to the foregoing and as follows:

1. SALE AND PURCHASE OF PROPERTY

         In consideration of the Purchase Price (as hereinafter defined) and
upon, and subject to, the terms and conditions hereinafter set forth, Seller
shall sell the Property to Purchaser, and Purchaser shall purchase the Property
from Seller (the "TRANSFER"). Purchaser acknowledges and agrees that no property
(real, personal or otherwise) owned by any other Person (other than Seller) is
intended to be conveyed hereunder.

2. PURCHASE PRICE

         2.1 The total purchase price (the "PURCHASE PRICE") for the Property
shall be Eleven Million Two Hundred Fifty Thousand and 00/100 ($11,250,000.00)
Dollars, to be paid in cash as follows:

               (a) Five Hundred Sixty Two Thousand Five Hundred and 00/100
($562,500.00) Dollars (the "DEPOSIT") to be paid by Purchaser by federal wire
transfer of immediately available funds to an account designated by Hogan &
Hartson L.L.P., 875 Third Avenue, New York, New York 10022, as escrow agent
("ESCROW AGENT"), or by certified or official bank check payable to Escrow
Agent, subject to collection, simultaneously with the execution of this
Agreement by Purchaser and as a condition to the effectiveness of this
Agreement, to be held and disbursed pursuant to the terms and conditions of
Section 11 of this Agreement; and

                                       2
<PAGE>

               (b) The balance of the Purchase Price over and above the Deposit
actually delivered by Purchaser to Escrow Agent (the "BALANCE") shall be paid by
Purchaser at the Closing by federal wire transfer of immediately available funds
to an account or accounts designated by Seller not less than one (1) Business
Day prior to Closing.

         2.2 All interest earned on the Deposit shall become a part of the
Deposit and shall be paid to the party entitled to the Deposit pursuant to this
Agreement. The Deposit shall be held by Escrow Agent on the terms set forth in
Section 11 and shall be disbursed in accordance with the provisions of this
Agreement regarding the Deposit. The parties hereby agree that, pending the
Closing, or the earlier termination of this Agreement, the Deposit shall be
deposited in an interest bearing account or in such other investment as the
parties may mutually agree. The Tax Identification Number of Purchaser is
13-3159796 and the Tax Identification Number of Seller is 13-1653578. In the
event the transaction contemplated by this Agreement is not consummated in
accordance with the terms hereof, the Deposit shall be delivered in accordance
with the applicable provisions of this Agreement.

3. INTENTIONALLY DELETED

4. TITLE MATTERS

         4.1 Purchaser agrees that it shall accept title to the Property subject
only to the following: (a) all non-delinquent real estate property taxes and
assessments (subject to apportionment as set forth hereinafter) and any lien to
secure same; (b) any Contracts assigned to, and assumed by, Purchaser; (c) the
matters set forth on Schedule 4.1 attached hereto; (d) all matters created by or
on behalf of, at the request of, or with the consent of, Purchaser, or arises as
a result of the acts of Purchaser, including, without limitation, any documents
or instruments to be recorded as part of any financing for the acquisition of
the Property by Purchaser; (e) any Violations (as hereinafter defined); (f) all
exceptions disclosed by the Title Report (as hereinafter defined) and the survey
relating to the Property, to the extent that same are approved or deemed
approved by Purchaser in accordance with this Section 4; (g) all Requirements of
Law (including, without limitation, those relating to building, zoning and land
use) affecting the development, use, occupancy or enjoyment of the Property; and
(h) exceptions that will not require Purchaser to pay or incur any additional
expense and that are of a de minimis nature (collectively, "PERMITTED
EXCEPTIONS").

                                       3
<PAGE>

         4.2 Purchaser acknowledges receipt of a copy of a title report having
an effective date of November 15, 2004 (the "TITLE REPORT"), prepared by
American Land Services, as Agent for Commonwealth Land Title Insurance Company
(the "TITLE COMPANY"). Purchaser may raise objections to any title exceptions
(including survey matters) disclosed by the Title Report or any updates to the
Title Report which are not Permitted Exceptions (collectively, "TITLE
OBJECTIONS"). Any Title Objections must be made within ten (10) days after (a)
the date hereof with respect to title exceptions contained in the Title Report
or (b) Purchaser's receipt of any such update, but in no event later than the
Closing Date. If Purchaser does not make any Title Objection within the
applicable period, such title exceptions will be deemed to be Permitted
Exceptions. Purchaser agrees to promptly deliver, or cause to be delivered, to
Seller copies of any and all updates to the Title Report after Purchaser's
receipt thereof. Within seven (7) Business Days after the receipt of a Notice
(as hereinafter defined) from Purchaser of any Title Objection(s), Seller shall
(subject to Seller's obligations under Section 4.4 hereof) give Purchaser a
Notice of any such Title Objection which Seller is unable or unwilling to cause
to be removed prior to or at Closing (a "SELLER OBJECTION NOTICE"). With respect
to any and all Title Objection(s) which are not Required Omissions (as
hereinafter defined) (all such other Title Objections, collectively, the
"ADDITIONAL TITLE ENCUMBRANCES") that are the subject of a Seller Objection
Notice, Purchaser shall elect, by Notice to Seller within five (5) days after
the giving of such Seller Objection Notice, either (A) to terminate this
Agreement, in which event the Deposit shall be promptly refunded to Purchaser,
or (B) to consummate the Transfer subject to any such Additional Title
Encumbrances as may exist as of the Closing Date, in which event Purchaser shall
not be entitled to any credit, nor shall Seller bear any liability, with respect
to any such Additional Title Encumbrances. Purchaser's failure to timely give
such Notice of election to Seller shall be deemed an election by Purchaser to
consummate the Transfer in accordance with clause (B) above.

         4.3 Purchaser shall purchase any fee title insurance policy obtained by
Purchaser in connection with the acquisition of the Property from the Title
Company or any other title insurance company licensed to do business in the
State of New York. If Purchaser is unwilling to accept such title insurance from
the Title Company (subject to Seller's obligations under Section 4.4 hereof),
Purchaser shall be required to close the Transfer subject to such Title
Objection(s), and upon failure to so close, Purchaser shall be deemed to be in
material default under this Agreement and the provisions of Section 7.5 hereof
shall apply. Notwithstanding any provision of this Article 4 to the contrary, in
the event that the Title Company, or any other title insurance company chosen by
Purchaser, is unwilling or unable to issue to Purchaser a fee title insurance
policy in connection with the acquisition of the Property which reflects the
state of title required to be delivered to Purchaser by Seller under this
Article 4, then, in such event, and if such fee title insurance reflecting such
state of title is available from Title Associates Inc., a Division of Stewart
Title Insurance Company, Purchaser shall be required to purchase any title
insurance required by Purchaser from Title Associates Inc., at Purchaser's sole
cost and expense, and such title company shall be deemed to be the "Title
Company" in all respects under this Article 4, except with respect to the
provisions of this sentence, and the title report prepared by such title company
shall be deemed to be the "Title Report" in all respects under this Article 4.

         4.4 Seller shall cause the Title Company to omit all Required Omissions
from Purchaser's lender's title policy and, with respect to Purchaser's owner's
title policy only, to omit or insure against enforcement of all Required
Omissions out of the Property. "REQUIRED

                                       4
<PAGE>

OMISSIONS" shall mean any Title Objections that (a) were caused by, resulted
from or arose out of a grant by Seller to any Person of a mortgage or security
interest affecting the Property; (b) are Liens placed by mechanics or
materialmen resulting from the performance of work on behalf of Seller upon all
or any part of the Property; or (c) constitute judgments or tax liens upon the
Property that are created or caused by Seller. In no event shall Seller have any
obligation or liability to spend any money or incur any expense to cause the
Title Company to remove, cure or insure against any Title Objections which are
not Required Omissions.

         4.5 Purchaser, at its expense, shall cause the existing survey of the
Property, if any, to be updated and re-certified, or have a new survey created
(the "SURVEY"), and shall deliver or cause same to be delivered to Seller.
Within five (5) Business Days after receipt of the Survey, Purchaser shall
notify Seller of any Title Objections (the "SURVEY OBJECTION NOTICE") based
thereon. Failure to timely deliver a Survey Objection Notice with respect to any
matter contained on the Survey shall constitute a waiver thereof. Purchaser's
objections to the Survey shall be governed in the same manner as Purchaser's
objections to title as set forth in this Section 4.

         4.6 Purchaser acknowledges that record title to the Property is
currently held by the Suffolk County Industrial Development Agency (the "IDA"),
and that the failure of Seller to hold record title to the Property and the
presence of any liens or encumbrances of any nature on the Property relating
thereto, shall not be deemed to be a Title Objection, and in connection
therewith, Purchaser further acknowledges and agrees that title to the Property
shall either be conveyed (a) to Seller by the IDA prior to Closing or (b) to
Purchaser directly by the IDA, at Seller's sole option (the "IDA TRANSFER").
Seller shall be permitted to use any portion of the Purchase Price for the
purpose of facilitating the IDA Transfer, including for the payment of legal
fees and costs.

5. UNPAID AMOUNTS

         5.1 The amount of any unpaid Taxes (as hereinafter defined), water
charges and sewer rents (subject to proration as provided in Section 8.1
hereof), which Seller is obligated to pay and discharge, with interest and
penalties (if any), to the Closing Date, may, at the option of Seller, be
allowed by Purchaser to be paid out of the Purchase Price, provided that
official bills therefor with interest and penalties thereon calculated to the
Closing Date are furnished by Seller at the Closing, and such Taxes shall not be
deemed to be Title Objections.

         5.2 Seller may use any portion of the Purchase Price to satisfy or bond
any Liens which exist on the Closing Date which are not Permitted Exceptions,
provided that Seller delivers to Purchaser at Closing instruments in recordable
form sufficient to satisfy such Liens, together with the cost of recording or
filing said instruments, or pays such sums or performs such acts (including,
without limitation, obtaining appropriate bonds) as will enable the Title
Company to insure Purchaser free of same as provided for in Section 4.4 hereof,
and such Liens shall not be deemed to be Title Objections.

         5.3 If Seller requests within a reasonable time prior to the Closing
Date, Purchaser agrees to provide at the Closing separate certified checks or
official cashier's checks, or to make various federal wire transfers of
immediately available funds, which in the aggregate equal the

                                       5
<PAGE>

amount of the Purchase Price in order to facilitate the satisfaction of any
unpaid (and due) Taxes, assessments, water charges or sewer rents referred to in
Section 5.1, and, if Seller elects to proceed pursuant to the provisions of
Section 5.2, the payment or bonding of any Liens referred to therein.

6. VIOLATIONS

         6.1 Seller shall have no obligation to comply with or cure, and
Purchaser shall accept title to the Property subject to any and all notes or
notices of violations of Legal Requirements noted in or issued by any
Governmental Entity having jurisdiction against or affecting the Property or
conditions which may give rise to the same (collectively, the "VIOLATIONS"),
including, but not limited to, Violations that are the obligation of the parties
under the Contracts to cure.

7. SETTLEMENT

         7.1 Time, Place and Conditions. Subject to any express right of
adjournment of Seller set forth in this Agreement, the settlement of the
Transfer under this Agreement (the "CLOSING") shall be held on the date which is
five (5) Business Days after the date that Seller gives a Closing Notice (as
hereinafter defined) to Purchaser (the "INITIAL CLOSING DATE"), at the offices
of Hogan & Hartson L.L.P. at 875 Third Avenue, New York, New York 10022 or, if
required by Purchaser's lender, if any, at the offices of such lender or its
counsel in the City of New York or the Counties of Nassau or Suffolk in the
State of New York. Notwithstanding the foregoing, either Seller or Purchaser
shall have the right from time to time to one or more adjournments of the
Closing, to a Business Day (an "ADJOURNED DATE") not later than ten (10)
Business Days after the Initial Closing Date, provided that such party delivers
written notice to the other party prior to the Initial Closing Date (or any
Adjourned Date, as the case may be) of such party's desire to adjourn the
Closing. TIME SHALL BE OF THE ESSENCE AS TO PURCHASER'S OBLIGATION to close by
3:00 P.M. Eastern Standard Time either on the Initial Closing Date or on any
Adjourned Date, subject to any express right of adjournment as provided in this
Agreement. TIME SHALL BE OF THE ESSENCE AS TO SELLER'S OBLIGATION to close by
3:00 p.m. Eastern Standard time on the Initial Closing Date or any Adjourned
Date, subject to any express right of adjournment as provided in this Agreement.
The actual date of the Closing is referred to herein as the "CLOSING DATE." In
the event that Seller has not given the Closing Notice to Purchaser within
seventy-five (75) days after the date hereof. Purchaser shall have the right,
within five (5) Business Days after the end of such seventy-five (75) day
period, to terminate this Agreement on Notice to Seller, in which even the
Deposit shall be refunded to Purchaser within five (5) Business Days, and the
parties shall have no further rights or obligations to the other except for
those items that, by the terms of this Agreement, expressly survive such
termination.

         7.2 Conditions to Closing.

                  Closing Date, provided that as of the Closing Date there shall
                  be no change from the date hereof with respect to the
                  representations contained in Sections 9.3(b) and (c); and

                  objections to the transactions contemplated hereby shall have
                  been timely made in response to the Sale Notice and/or at

                  (b) The obligation of Purchaser to purchase the Property from

                  in all material respects, with every covenant, agreement and
                  condition required by this Agreement to be performed or
                  complied with by Seller on or before the Closing Date; and

                           (ii) The representations and warranties of Seller
                  shall be true and correct in all material respects as of the
                  Closing Date, provided that as of the Closing Date there shall
                  be no change from the date hereof with respect to the
                  representations contained in Section 9.2(b).

                  The conditions set forth in the foregoing clauses (i) and (ii)
are for the sole benefit of Purchaser and may be waived, in whole or in part, by
Purchaser in its sole and absolute discretion.

         7.3 Costs and Expenses.

contemplated hereby, and obtaining third party consents to the performance of
that party's obligations under this Agreement. Notwithstanding the foregoing:

                           (i) Purchaser will be responsible for all fees and
                  costs of any financial advisor to Purchaser, and Seller will
                  be responsible for all fees and costs of any financial advisor
                  to Seller;

                           (ii) Purchaser will be responsible for all costs,
                  fees and expenses of (A) its due diligence, including without

                  Purchaser's owner's title insurance policy and the
                  endorsements or extended coverage thereto (including all Title
                  Company charges, title insurance premiums, title examination
                  and other costs);

                           (iii) At the Closing, Seller shall pay the New York
                  State Transfer Tax in accordance with Article 31 of the New
                  York State Tax Law (the "TRANSFER TAX"), which shall be due on
                  the Transfer;

                           (iv) At the Closing, Seller shall pay all fees and
                  recording charges for releasing or bonding Liens (other than
                  the Permitted Exceptions) which Seller has an obligation or
                  elects to remove or bond, including prepayment premiums or
                  penalties, if any. All other recording fees shall be borne and
                  paid by Purchaser at the Closing, including, without
                  limitation, the costs of recording the Deed (as hereinafter
                  defined); and

                           (v) Any other costs, charges and expenses shall be
                  borne and paid as provided in this Agreement, or in the
                  absence of such provision, in the manner recommended by the
                  Customs in Respect to Title Closings of the Real Estate Board
                  of New York, Inc.

                  (b) The provisions of this Section 7.3 shall survive the
Closing.

         7.4 Seller's Default. If Purchaser is ready, willing and able to
consummate the transactions contemplated by this Agreement and Seller shall fail
to perform its material obligations hereunder and to make full settlement in
accordance with the terms hereof, Purchaser may elect, as its sole and exclusive
remedy for such failure to perform on the part of Seller either (a) to terminate
this Agreement on Notice to Seller, in which event the Deposit shall be refunded
to Purchaser within five (5) Business Days, and the parties shall have no
further rights or obligations to the other except for those items that, by the
terms of this Agreement, expressly survive such termination, or (b) to seek
specific performance of Seller's obligations under this Agreement, provided,
however, that specific performance shall only be available if Purchaser shall
notify Seller that Purchaser has elected to pursue its right of specific
performance within forty-five (45) days after the date of the Closing then
scheduled pursuant to this Agreement at the time of the alleged default
hereunder by Seller ("SELLER'S ALLEGED DEFAULT DATE") and commence an action
seeking specific performance in a court of competent jurisdiction within ninety
(90) days after Seller's Alleged Default Date. If Purchaser shall fail to
deliver such notice within such forty-five (45) day period or shall fail to
commence such action within such ninety (90) day

                                       8
<PAGE>

period, Purchaser shall be deemed to have waived Purchaser's right to seek
specific performance and Purchaser shall be deemed to have elected to terminate
this Agreement as provided in clause (a) above. Notwithstanding the foregoing,
Purchaser shall have the right to waive any default of Seller, in whole or in
part, in its sole and absolute discretion, and proceed to Closing without any
credit or adjustment to the Purchase Price or further liability of Seller with
respect to such default.

         7.5 Purchaser's Default. If Section 7.4 hereof shall not be applicable
and Purchaser is in default and fails to perform any of its material obligations
under this Agreement including, without limitation, a failure to fully and
completely comply with the conditions to Closing set forth in Section 7.2(a)
hereof, then the Deposit shall be promptly disbursed to Seller. Upon receipt of
the Deposit by Seller, Seller shall retain the Deposit as liquidated damages,
and Seller shall have no obligation to convey title to the Property to
Purchaser, and except as expressly provided in this Agreement, upon such
disbursement of the Deposit to Seller, this Agreement shall be absolutely,
automatically and completely null, void and of no further force or effect.
Enforcement of Seller's right to receive the Deposit and the retention of the
Deposit, when disbursed to, and retained by Seller as liquidated damages, shall
be Seller's sole remedy in the event of Purchaser's default hereunder. THE
PARTIES HERETO EXPRESSLY AGREE AND ACKNOWLEDGE THAT SELLER'S ACTUAL DAMAGES IN
THE EVENT OF A DEFAULT BY PURCHASER WOULD BE EXTREMELY DIFFICULT OR
IMPRACTICABLE TO ASCERTAIN AND THAT THE DEPOSIT REPRESENTS THE PARTIES'
REASONABLE ESTIMATE OF SUCH DAMAGES. Notwithstanding the foregoing, Seller shall
have the right to waive any default of Purchaser, in whole or in part, in its
sole and absolute discretion, and proceed to Closing without any credit or
adjustment to the Purchase Price or further liability of Purchaser with respect
to such default.

Seller and Purchaser as of 11:59 P.M. Eastern Standard Time of the day prior to
the Closing Date (the "CUTOFF") with respect to the Property and the net amount
thereof either shall be paid by Purchaser to Seller or credited to Purchaser, as
the case may be, at the Closing:

                                       11
<PAGE>

                  (a) real property taxes and assessments (or installments
thereof), including any payments in lieu of taxes and payments required to be
made to any business improvement district, and vault charges affecting the Land
and/or the Building (collectively, "TAXES");

                  (b) water rates and charges;

                  (c) sewer taxes and rents;

                  (d) permit, license and inspection fees, if any, with respect
to the Permits on the basis of the fiscal year for which levied along with any
deposits thereunder, if the rights with respect thereto are transferred to
Purchaser at Closing, and Seller shall receive a credit at Closing in the amount
of such deposit(s);

                  (e) electricity, gas, telephone and any other utilities, at
the rates most recently charged to Seller, plus sales taxes thereon, except in
the event that Purchaser arranges for new accounts for any such utility, and the
service provided to Seller is terminated, as of the Closing;

                  (f) fees and other charges paid or payable by Seller or paid
or payable to Seller, under any Contracts not terminated at or prior to Closing
and assumed by Purchaser;

                  (g) the value of Building inventory and supplies in customary
quantities (e.g., soap, cleaning powder, light bulbs, etc.) in unopened
containers in the Building, if any, in accordance with an inventory prepared by
Seller or its agent, shall be credited to Seller. Such value amount shall be
determined based upon Seller's cost thereof, as evidenced by actual invoices;
and

                  (h) premiums for any assignable insurance policies which
Seller and Purchaser agree shall be assigned to Purchaser and which are actually
assigned to Purchaser.

         8.2 Taxes; Water and Sewer.

                  (a) Apportionment of Taxes, water rates and charges, sewer
taxes and rents shall be made on the basis of the fiscal year for which
assessed. If the Closing Date shall occur before the Taxes, water rates or
charges, sewer taxes or rents are fixed, apportionment for any item not yet
fixed shall be made on the basis of the real property tax rate, water rates and
charges, sewer taxes and rents or vault charges, as applicable, for the
preceding year applied to the latest assessed valuation. After the Taxes, water
rates and charges, sewer taxes and rents are finally fixed, Seller and Purchaser
shall make a recalculation of the apportionment of same, and Seller or
Purchaser, as the case may be, shall make an appropriate payment to the other
based upon such recalculation.

                  (b) The amount of any unpaid Taxes, water charges and sewer
rents which Seller is obligated to pay and discharge, with interest and
penalties thereon (if any) to the Closing Date may, at Seller's option, be
credited to Purchaser.

                  (c) If any refund or credit of Taxes, water rates or charges,
sewer taxes or rents is made after the Closing Date for a period prior to the
Closing Date, the same shall be applied first to the reasonable out-of-pocket
third party costs incurred in obtaining same and the

                                       12
<PAGE>

balance, if any, of such refund shall, to the extent received by Purchaser, be
paid to Seller (to the extent relating to the period through the Cutoff), and to
the extent received by Seller, be paid to Purchaser (to the extent relating to
the period commencing with the Closing Date).

                  (d) Seller shall use good faith efforts to obtain readings of
the meters measuring water consumption or sewer usage, electricity and gas, if
any, at the Property to a date not more than fifteen (15) days prior to the
Closing Date. If such readings are not obtained (and if such readings are
obtained, then with respect to any period between such reading and the Cutoff),
water rates and charges and sewer taxes and rents, electricity and gas, if any,
shall be apportioned based upon the last meter readings, subject to
reapportionment when readings for the relevant period are obtained after the
Closing Date as provided in Section 8.3(b) below.

         8.3 Miscellaneous.

                  (a) Prior to the Closing, Seller shall prepare and deliver to
Purchaser a statement (the "PRELIMINARY PRORATION STATEMENT") showing
apportionments for the items set forth above, calculated as of the Cutoff, on
the basis of the actual days in a particular month and a 365-day calendar year.
Purchaser and Seller shall agree upon any adjustments to be made to the
Preliminary Proration Statement prior to the Closing, and at the Closing,
Purchaser or Seller, as applicable, shall receive a credit equal to the net
amount due Purchaser or Seller, pursuant to the Preliminary Proration Statement
as finally agreed upon by Purchaser and Seller (as so approved by Seller and
Purchaser, the "SETTLEMENT STATEMENT").

                  (b) If final prorations cannot be made on the Closing Date for
any item being prorated under this Article 8 or, if there is an error in the
calculation of any proration, then Purchaser and Seller agree to allocate such
items on a fair and equitable basis as soon as invoices or bills are available
or after such items are finally fixed, with final adjustment to be made as soon
as reasonably possible after the Closing Date (but in no event later than six
(6) months after the Closing Date). If such final adjustment discloses that any

9.       REPRESENTATIONS, WARRANTIES, COVENANTS AND ACKNOWLEDGMENTS

         9.1 Covenants of Seller.

                  (a) Seller hereby covenants and agrees that during the period
commencing on the date of execution of this Agreement and ending on the Closing
Date or the earlier termination of this Agreement:

                           (i) Seller shall not enter into any Lease without the
                  consent of Purchaser, which consent may be granted or withheld
                  in Purchaser's sole and absolute discretion.

                           (ii) Except in connection with the IDA Transfer,
                  Seller shall not sell, assign, mortgage, pledge, encumber or
                  otherwise transfer all or any portion of the Property or take
                  any other affirmative action affecting title to the Property,
                  or enter into a written agreement to do any of the foregoing,
                  without the prior written consent of Purchaser, which may be
                  granted or withheld in Purchaser's sole and absolute
                  discretion. Notwithstanding the foregoing, if any mortgage,
                  pledge or encumbrance shall affect the Property as of the
                  Closing Date, the foregoing shall not be deemed a default
                  under this Section 9.1(a)(ii) but shall be dealt with in
                  accordance with Article 4 herein.

                           (iii) Seller shall continue to operate, maintain and
                  repair the Property in accordance with its current business
                  practices so as to deliver the Property to Purchaser in
                  substantially its present or, at Seller's sole discretion,
                  better, condition, ordinary wear and tear and damage from
                  casualty or condemnation excepted, or otherwise in the
                  condition required under this Agreement. In addition, Seller
                  may, but shall not be required to, perform any maintenance,
                  alterations, repairs or renovations, (A) as expressly
                  permitted by the terms of this Agreement following a casualty
                  or condemnation or (B) as required by any Legal Requirement.
                  Seller shall have the right, either in its own name, or in the
                  name of Sutton & Edwards (the "MANAGING AGENT"), to hire or
                  terminate employees in connection with the operation of the
                  Property, provided that any such employees shall be terminated
                  on or before the Closing and Purchaser shall have no
                  obligation with respect thereto. Seller shall not remove from
                  the Property any Building Equipment unless replaced by
                  property of similar or better quality, provided that in no
                  event shall Seller be obligated to Purchaser for any de
                  minimis items of Building Equipment which are lost or missing
                  as of the Closing Date. Notwithstanding the foregoing
                  provisions of this Section 9.1(a)(iii), Seller shall, at
                  Seller's sole cost, perform the work listed on Schedule
                  9.1(a)(iii) annexed hereto, (collectively, "SELLER'S WORK").
                  Notwithstanding anything to the contrary provided for in this
                  Agreement, the substantial completion of Seller's Work: (1) is
                  not and shall not be deemed to be a condition of Closing, (2)
                  in the event that Seller's Work is not fully performed at
                  Closing, then Purchaser shall be entitled to be paid at
                  Closing for the estimated cost of the actual and reasonable
                  out-of-pocket costs to be incurred by Purchaser after the
                  Closing in performing the unperformed portion of Seller's
                  Work, as reasonably estimated by Purchaser and

                                       14
<PAGE>

                  Seller. Seller shall have no obligations or liabilities and
                  Purchaser shall have no rights or remedies with respect to
                  Seller's Work other than Seller's obligations and Purchaser's
                  rights as set forth in this Section 9.1(a)(iii).

                           (iv) Seller shall have the right to enter into New
                  Contracts to operate the Property, provided that Seller shall
                  not enter into any New Contracts that would survive the
                  Closing and be binding upon Purchaser without Purchaser's
                  prior written consent, which Purchaser may grant or withhold
                  in Purchaser's sole and absolute discretion. Except for
                  Contracts that Seller and Purchaser, in their sole and
                  absolute discretion, mutually agree to have assigned to, and
                  assumed by Purchaser, Seller shall terminate, at Seller's sole
                  cost and expense, any Contract that does not expire by its
                  terms on or before the Closing Date.

                           (v) Seller shall keep Purchaser reasonably apprised
                  of progress made in connection with either giving of the Sale
                  Notice and/or obtaining the Approval Order, provided that in
                  no event shall Purchaser have any approval rights in
                  connection with such procedures.

                  (b) Seller shall commence service of the Sale Notice to each
party to whom service is deemed necessary or desirable by Seller within four (4)
Business Days after the date that this Agreement is fully executed and each
party has delivered a signed original of its signature to the other party.
Seller shall give Notice to Purchaser of the commencement of the service of the
Sale Notice within one (1) Business Day after the end of such four (4) Business
Day period. If Seller fails to timely give such Notice then Purchaser shall
elect, by Notice to Seller within two (2) Business Days after the failure of
Seller to timely give such Notice, either (i) to terminate this Agreement, in
which event the Deposit shall be refunded to Purchaser within five (5) Business
Days, or (ii) to consummate the Transfer. Purchaser's failure to timely give
such Notice of election to Seller shall be deemed an election by Purchaser to
consummate the Transfer in accordance with clause (ii) above.

                  (c) If, pursuant to any provision of Section 9.1(a),
Purchaser's consent is required, such consent shall not be unreasonably delayed.
To that end, if Purchaser fails to respond to any written request for consent
pursuant to Section 9.1(a) within five (5) Business Days, Purchaser shall be
deemed to have consented to such request.

         9.2 Representations and Warranties of Seller. Seller represents and
warrants to Purchaser that the following matters are materially true and correct
as of the execution of this Agreement:

in accordance with their respective terms (except to the extent that such
enforcement may be limited by applicable bankruptcy, insolvency, moratorium and
other principles relating to or limiting the right of contracting parties
generally) and does not and will not violate any provisions of any agreement to
which Seller is a party or to which it is subject. As of the Closing Seller
shall not be subject to any law, order, decree or restriction which prohibits or
would be violated by this Agreement or consummation of the transactions
contemplated hereby;

the Property;

domain or similar proceedings are pending with respect to the Property.

                    Seller shall deliver a certification to Purchaser at Closing
indicating whether as of the Closing, there have been any material changes in
circumstances relating to such representations and warranties between the date
hereof and the Closing Date, provided that any such change in circumstance shall
not give rise to any liability whatsoever of Seller to Purchaser, except that
Purchaser shall have any rights expressly provided for in this Agreement.

restriction which prohibits or would be violated by this Agreement or
consummation of the transactions contemplated hereby; and

                  (c) There are no voluntary or involuntary Bankruptcy Actions

         9.4 Acknowledgments of Purchaser; As-Is, Where-Is.

                  (a) Purchaser hereby expressly acknowledges and agrees that,
except as otherwise expressly set forth in this Agreement, as reliance thereon

                  (c) SELLER DOES NOT MAKE AND HAS NOT MADE AND SPECIFICALLY
DISCLAIMS ANY REPRESENTATION OR WARRANTY REGARDING THE COMPLIANCE OR
NON-COMPLIANCE OF THE PROPERTY WITH THE AMERICANS WITH DISABILITIES ACT, OR ANY

except for Seller's representations and warranties expressly set forth in this
Agreement, as reliance thereon and enforcement thereof is expressly limited in
this Agreement, Purchaser waives, and Seller disclaims, all warranties of any

implied, including, by way of description but not limitation, those of fitness
for a particular purpose and use.

                  (f) Purchaser acknowledges that Purchaser has had an adequate
opportunity to make such legal, factual and other inquiries and investigations

<PAGE>

agrees that, except as otherwise expressly provided in this Agreement, Purchaser
is solely responsible for obtaining any approval or permit necessary for

alterations necessary to obtain the approval or permit, all at Purchaser's sole
cost and expense.

                  (h) The provisions of this Section 9.4 shall survive the
Closing.

         9.5 Release.

                  (a) Without limiting the provisions of Section 9.4, effective
as of the Closing Date, Purchaser, for itself and any of its successors and
assigns and their Affiliates, hereby irrevocably and absolutely waives its right
to recover from, and forever releases and discharges, and covenants not to file
or otherwise pursue any legal action against, Seller, SAirGroup AG and/or their
Affiliates or any direct or indirect partner, member, manager, trustee,
director, shareholder, controlling person, officer, attorney, employee, agent,
broker, representative (including, without limitation, the Liquidator) or
Affiliate of any of the foregoing, and any of their respective heirs,
successors, personal representatives and assigns (each, a "SELLER PARTY", and
collectively, the "SELLER PARTIES"), with respect to any and all suits, actions,
proceedings, investigations, demands, claims, liabilities, fines, penalties,
liens, judgments, losses, injuries, damages, settlement expenses or costs of
whatever kind or nature, whether direct or indirect, known or unknown,
contingent or otherwise (including any action or proceeding brought or
threatened or ordered by any Governmental Entity), including, without
limitation, attorneys' and experts' fees and expenses, and investigation and
remediation costs that may arise on account of or in any way be connected with
the condition of the Property or any portion thereof as of the Closing Date
(collectively, "CLAIMS"), including, without limitation, the physical,
environmental and structural condition of the Property or any Legal Requirement
applicable thereto, or any other matter relating to the use, presence, discharge
or release of Hazardous Materials on, under, in, above or about the Property.
The foregoing provision of this Section 9.5 shall not apply with respect to any
Claim by Purchaser against (i) any Seller Party for any act of that Seller Party
that constitutes fraud or (ii) Seller for any breach of the representations,
warranties, covenants or other agreements set forth in this Agreement that
expressly survive the Closing, but only for the period of such survival.
Purchaser expressly waives the benefits of any provision or principle of a Legal
Requirement that may limit the scope or effect of the foregoing waiver and
release.

                  (b) The provisions of this Section 9.5 shall survive the
Closing.

10. CASUALTY, CONDEMNATION

         10.1 If, prior to the Closing, any part of the Property is damaged or
destroyed by earthquake, flood, landslide, fire or other casualty (a
"CASUALTY"), or any portion of the Property is taken by eminent domain or
condemnation proceeding (a "CONDEMNATION"), and such Casualty or Condemnation is
a Non-Material Event (as hereinafter defined), (a) Purchaser shall not have any
right or option to terminate this Agreement due to such Casualty or Condemnation
and this Agreement shall remain in full force and effect, (b) the parties shall
consummate the Transfer without any reduction in the Purchase Price and (c) at
the Closing Purchaser shall accept the Property "AS-IS, WHERE-IS" subject to
such Casualty or Condemnation (or so much of the Property as remains after such
Casualty or Condemnation), as the case may be.

                                       19

<PAGE>

Notwithstanding the foregoing, at the Closing, (i) in the case of a Casualty,
(A) Seller shall turn over and/or assign to Purchaser (without representation,
warranty or recourse against Seller) the right to receive, and Purchaser shall
be entitled to receive and keep, all casualty insurance proceeds paid or payable
to Seller, if any, under insurance policy(ies) with respect to such Casualty
(and Seller shall have no obligation to repair such casualty), (B) Seller shall
credit to Purchaser at the Closing the amount of any insurance deductible and
(C) Purchaser shall pay to Seller at Closing the amount of the actual,
reasonable expenses incurred by Seller in making repairs occasioned by such
Casualty which are required by applicable Legal Requirements, or which Seller,
in its reasonable discretion, deems necessary for public safety reasons or to
maintain or preserve the Property to the standards as of the date hereof, or,
(ii) in the case of a Condemnation, (A) Seller shall turn over and/or assign to
Purchaser (without representation, warranty or recourse against Seller) the
right to receive, and Purchaser shall be entitled to receive and keep, all
condemnation awards, if any, paid or payable to Seller with respect to such
Condemnation, and (B) Purchaser shall pay to Seller at Closing the amount of the
actual, reasonable expenses incurred by Seller in making repairs to the Property
which are required by applicable Legal Requirements, or which Seller, in its
reasonable discretion, deems necessary for public safety reasons or to maintain
or preserve to the standards as of the date hereof, occasioned by such
Condemnation.

         10.2 If a Casualty occurs, or all or any portion of the Property is
taken by Condemnation prior to the Closing, Seller shall notify Purchaser of
such fact promptly after obtaining knowledge thereof and, if and only if such
Casualty constitutes a Material Event, Purchaser shall have the right to
terminate this Agreement by giving Notice to Seller (and to Escrow Agent) not
later than ten (10) days after receipt of Seller's Notice of such Casualty which
is a Material Event, in which event this Agreement shall terminate on the date
of the giving of such Notice by Purchaser (except for those provisions of this
Agreement that survive any termination of this Agreement) and Escrow Agent shall
disburse the Deposit to Purchaser within five (5) Business Days after Escrow
Agent receives Notice of such termination. If Purchaser fails to elect to
terminate this Agreement as aforesaid within such ten (10) day period, Purchaser
shall be deemed to have waived such termination right with respect to such
Casualty or Condemnation and the provisions of Section 10.1 shall apply as if
such Casualty or Condemnation were a Non-Material Event. A "MATERIAL EVENT" with
respect to the Property means (a) any damage by Casualty if the cost of
restoration or repair of such Casualty is reasonably anticipated to exceed
$562,500 to repair or restore or (b) any taking by Condemnation (i) of at least
five (5%) percent of the gross number of square feet contained in the Building,
(ii) that would decrease the parking spaces now existing or potentially existing
on the Property to a level that is not in compliance with applicable Legal
Requirements and (iii) that would eliminate access to the Property from all
public streets, roads, avenues, alleys, expressways and highways. A
"NON-MATERIAL EVENT" with respect to the Property means any Casualty or
Condemnation which is not a Material Event.

         10.3 Seller shall promptly provide to Purchaser copies of any
correspondence relating to any claims related to any Casualty or Condemnation
under the relevant insurance policies or against the Governmental Entity
effecting the Condemnation, and shall promptly advise Purchaser of all material
developments concerning such claims. Seller shall not settle or compromise any
claims related to any Casualty or Condemnation under the relevant insurance
policies or against the Governmental Entity effecting the Condemnation without
Purchaser's consent, which consent may not be unreasonably withheld, delayed or
conditioned. Seller shall

                                       20
<PAGE>

cooperate with Purchaser to effect the assignment of the right to receive
insurance or condemnation proceeds to Purchaser and will execute and deliver all
such instruments as are reasonably necessary to complete that assignment.

         10.4 The provisions of this Section 10 shall be construed as express
provisions in lieu of the provisions of the Uniform Vendor and Purchaser Risk
Act, which the parties agree shall be inapplicable to the transactions
contemplated hereby.

         10.5 The provisions of this Section 10 shall survive the Closing, but
not the earlier termination of this Agreement.

11. ESCROW AGENT

         11.1 Escrow Agent. Escrow Agent accepts its appointment hereunder
subject to the following conditions:

                  (a) Escrow Agent shall hold the Deposit and all interest
accrued thereon in escrow in an interest bearing escrow account maintained at a
bank selected by Escrow Agent that is insured by the Federal Deposit Insurance
Corporation (the "DEPOSITORY") (but Escrow Agent shall be under no duty to
maximize the rate of return on the Deposit or to insure against any reduction in
the value of the Deposit by reason of any loss in value of any security in which
the Deposit is invested). The Escrow Agent may commingle the Deposit with escrow
funds of others.

                  (b) Escrow Agent shall pay over or apply the Deposit in
accordance with the terms of this Agreement. All interest accrued on the Deposit
shall be paid to the party entitled to payment of the Deposit. The party who
receives the interest accrued on the Deposit shall pay all income taxes thereon.

                  (c) Escrow Agent shall be liable only for loss or damage
resulting from the malfeasance or gross negligence of Escrow Agent or its
partners or employees and shall not be liable for loss or damage resulting from:
(i) any good faith act or forbearance of Escrow Agent or its partners or
employees; (ii) any default, error, action or omission of any party, other than
Escrow Agent; (iii) the expiration of any time limit or other delay which is not
solely caused by the failure of Escrow Agent to proceed in its ordinary course
of business, and in no event where such time limit is not disclosed in writing
to the Escrow Agent; (iv) Escrow Agent's compliance with all attachments, writs,
orders, judgments or other legal process issued out of any court; or (v) Escrow
Agent's assertion or failure to assert any cause of action or defense in any
judicial or administrative proceeding.

                  (d) Investment of the Deposit shall be subject to the rules,
regulations, policies and procedures of the Depository.

                  (e) If for any reason any party makes a written demand upon
Escrow Agent for payment of any part of the Deposit, Escrow Agent shall give at
least ten (10) Business Days' prior written notice to the other party hereto of
Escrow Agent's intention to pay over the Deposit in accordance with such demand
on a stated date (which date shall be at least ten (10) Business Days after the
giving of such notice to the other party). If Escrow Agent does not receive a

                                       21
<PAGE>

written objection from the other party to the proposed payment before such
stated date, Escrow Agent is hereby authorized and directed to pay the Deposit
to the party claiming to be entitled thereto. If Escrow Agent does receive
written objection before such payment, Escrow Agent shall continue to hold the
Deposit until otherwise directed by written instructions from each of Seller and
Purchaser or until resolution of any dispute by judicial or non-judicial
procedure agreed upon by Seller and Purchaser and delivery of a copy of any
final judicial order or non-judicial decision to Escrow Agent, whereupon Escrow
Agent shall disburse the Deposit as provided in such joint instructions, order
or decision.

                  (f) If Escrow Agent is made a party to any judicial,
non-judicial or administrative action, hearing or process based on acts of any
of the other parties hereto and not on the malfeasance and/or gross negligence
of Escrow Agent in performing its duties hereunder, the expenses, costs and
reasonable attorney fees incurred by Escrow Agent in responding to such action,
hearing or process may be deducted from the funds held hereunder and the
party/parties whose alleged acts are a basis for such proceedings shall
indemnify, save or hold Escrow Agent harmless from said expenses, costs and fees
so incurred.

                  (g) It is expressly understood that Escrow Agent acts
hereunder as a stakeholder for the convenience and accommodation of the parties
hereto and as a depository only and is not responsible or liable in any manner
whatsoever for the sufficiency, correctness, genuineness or validity of any
instrument received by or deposited with it, or for the form of execution of
such instruments, or for the identity, authority or right of any person
executing or depositing the same, or for the terms and conditions of any
instrument pursuant to which Escrow Agent may act.

                  (h) The duties of Escrow Agent are purely ministerial. Escrow
Agent shall not have any duties or responsibilities except those set forth in
this Agreement and shall not incur any liability in acting upon any signature,
notice, request, waiver, consent, receipt or other paper or document believed by
Escrow Agent to be genuine, and Escrow Agent may assume that any person
purporting to give it any notice on behalf of any party in accordance with the
provisions hereof has been duly authorized to do so.

                  (i) Escrow Agent may resign upon ten (10) days' prior notice
to each of Seller and Purchaser and by (i) depositing the Deposit with any Court
or the Clerk of the County of New York, New York or (ii) transferring the
Deposit to a bank or other institution acceptable to Seller and Purchaser which
shall have assumed in writing the obligations of Escrow Agent pursuant to this
Agreement. Upon the effective date of such resignation, Escrow Agent shall have
no further obligations arising hereunder and shall be released from all
liability arising out of this Agreement, except its misapplication of any
portion of the Deposit or its gross negligence or willful misconduct.

                  (j) Escrow Agent may act or refrain from acting in respect of
any matter referred to herein in full reliance upon and by and with the advice
of counsel which may be selected by it.

                  (k) Seller and Purchaser hereby jointly and severally agree,
with the right of contribution against each other, to indemnify and save Escrow
Agent harmless from any and all

                                       22
<PAGE>

loss, damage, claim, liability, judgment and other cost and expense of every
kind and nature which may be incurred by Escrow Agent by reason of its
acceptance of, and its performance under, this Agreement (including, without
limitation, reasonable attorneys' fees), except in the case of its own
malfeasance or gross negligence.

                  (l) Purchaser acknowledges that Escrow Agent is also counsel
to Seller in connection with this transaction. Notwithstanding that fact,
Purchaser agrees that Escrow Agent may continue to act as counsel to Seller in
connection herewith and in connection with any other transaction between Seller
and Purchaser and in connection with any dispute, action, cause of action or
claim arising out of this transaction or any other transaction between Seller
and Purchaser, provided that the matter at issue does not involve the
performance of Escrow Agent's services hereunder.

                  (m) Upon delivery of the Deposit in accordance with the terms
of this Agreement, Purchaser and Seller hereby release Escrow Agent from all
obligation and liability hereunder. In furtherance of the foregoing, at the
Closing, Seller and Purchaser shall execute and deliver to Escrow Agent an
agreement in writing (i) authorizing Escrow Agent to deliver the Deposit to
Seller and (ii) releasing Escrow Agent from any liability in connection with the
performance of its obligations hereunder, and the Deposit shall be paid by
Escrow Agent as provided herein.

         13.2 Governing Law. This Agreement shall be construed and enforced in
accordance with the laws of the State of New York, regardless of the laws that
might otherwise govern under applicable conflicts of law principles thereof.

         13.3 Interpretation. When a reference is made in this Agreement to a
Section, Exhibit or Schedule such reference will be to a Section, Exhibit or
Schedule of or to this Agreement unless otherwise indicated. The table of
contents and headings contained in this Agreement are for reference purposes
only and will not affect in any way the meaning or interpretation of this
Agreement. All words or terms used in this Agreement, regardless of the number
or gender in which they are used, shall be deemed to include any other number
and any other gender as the context may require. The plural of any term

                                       25
<PAGE>

defined in the singular, and the singular of any term defined in the plural,
shall have a meaning correlative to such defined term. Whenever the words
"include", "includes" or "including" are used in this Agreement, they will be
deemed to be followed by the words "without limitation." No provision of this
Agreement will be interpreted in favor of, or against, any of the parties to
this Agreement by reason of the extent to which such party or its counsel
participated in the drafting thereof or by any reason of the extent to which
such provision is consistent with any prior draft hereof.

         13.4 Binding Effect. Subject to the provisions of Section 13.11 below,
this Agreement shall be binding upon, and inure to the benefit of, the parties
hereto and their respective legal representatives, heirs, executors,

the Exhibits and Schedules attached hereto contain the final and entire
agreement between the parties hereto with respect to the sale and purchase of
the Property and are intended to be an integration of all prior negotiations and
understandings, both written and oral, between the parties with respect to the
subject matter of this Agreement. Purchaser, Seller and their agents shall not
be bound by any terms, conditions, statements, warranties or representations,
oral or written, not contained herein. This Agreement shall not confer any
rights or remedies upon any Person other than the parties hereto, the Persons
entitled to indemnification hereunder, and in each case their respective
successors, heirs, legal representatives and permitted assigns.

         13.6 Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction will, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision will be interpreted
to be only so broad as is enforceable.

         13.7 Attorneys' Fees. If any action is brought by either party against
the other in connection with or arising out of this Agreement or any of the
documents and instruments delivered in connection herewith or in connection with
the transactions contemplated hereby, the prevailing party shall be entitled to
recover from the other party reasonable attorneys' fees and expenses incurred in
connection with the prosecution or defense of such action. The provisions of
this Section 13.7 shall survive the Closing or earlier termination of this
Agreement.

         13.8 Enforcement; Jurisdiction.

                  (a) Any legal action or proceeding with respect to this
Agreement shall be brought in a Federal or state court of competent jurisdiction
sitting in the City, County and State of New York (including the appellate
courts thereof) (each, a "NEW YORK COURT") and by execution and delivery of this
Agreement, each party to this Agreement hereby accepts, generally and
unconditionally, the jurisdiction of the New York Courts. Each party to this
Agreement hereby expressly and irrevocably submits the person of such party to
this Agreement to the personal jurisdiction of the New York Courts in any suit,
action or proceeding arising, directly or indirectly, out of or relating to this
Agreement. To the extent permitted under applicable law, this consent to
personal jurisdiction shall be self-operative and no further

                                       26
<PAGE>

instrument or action, other than service of process in one of the manners
specified in this Agreement or as otherwise permitted by law, shall be necessary
in order to confer jurisdiction upon the person of such party to this Agreement
in any such New York Court.

                  (b) To the fullest extent permitted under applicable law, each
party to this Agreement irrevocably waives and agrees not to assert, by way of
motion, as a defense or otherwise, any objection which it may now or hereafter
have to the laying of the venue of any such suit, action or proceeding brought
in a New York Court and any claim that any such suit, action or proceeding has
been brought in an inconvenient forum, any claim that it is not personally
subject to the jurisdiction of any such New York Court or that this Agreement or
the subject matter hereof may not be enforced in or by such New York Court.

                  (c) The provisions of this Section 13.8 shall survive the
Closing or the earlier termination of this Agreement.

         13.9 Waiver. No waiver by either party of the other party's breach of
any term, covenant or condition contained in this Agreement shall be deemed to
be a waiver of any subsequent breach of the same or any other term, covenant or
condition of this Agreement. In addition, no waiver of any of the provisions of
this Agreement shall be valid unless the same is in writing and is signed by the
party against which it is sought to be enforced.

         13.10 Amendment. This Agreement may only be modified or amended by a
written instrument duly executed by authorized representatives of the parties.

         13.11 Assignments. Purchaser may not assign this Agreement, nor any of
the rights, interests or obligations hereunder, directly or indirectly
(including without limitation, any direct or indirect change in equity
structure, ownership or control of any Person which is the Purchaser), in whole
or in part, by operation of law or otherwise, without Seller's prior written
consent to any Person, and any such assignment made without Seller's consent
shall be void ab initio. Notwithstanding the foregoing, Purchaser shall have the
right to designate a wholly-owned Affiliate formed and validly existing in the
United States to take title to the Property, provided, that in the event of any
such assignment, Purchaser will remain liable to Seller with respect to all
liabilities and obligations under this Agreement. Any assignment permitted by
the immediately prior sentence shall only be permitted and deemed effective if
Purchaser shall notify Seller of same no later than five (5) Business Days prior
to the Closing and such notice is accompanied by (a) a copy of such assignment
document (whereby assignee assumes all obligations of Purchaser under this
Agreement) and (b) a certification from assignee that any such assignee does not
violate the provisions of the foregoing sentence.

         13.12 Waiver of Trial by Jury. SELLER AND PURCHASER HEREBY WAIVE TRIAL
BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER ARISING IN TORT OR
CONTRACT) BROUGHT BY SUCH PARTY AGAINST THE OTHER ON ANY MATTER ARISING OUT OF
OR IN ANY WAY CONNECTED WITH THIS AGREEMENT. THE PROVISIONS OF THIS SECTION
13.12 SHALL SURVIVE THE CLOSING OR EARLIER TERMINATION OF THIS AGREEMENT.

                                       27
<PAGE>

         13.13 Limitation of Liability. Notwithstanding anything to the contrary
contained in this Agreement, it is understood and agreed that none of the
employees, directors, officers, members, partners, managers, principals,
consultants, shareholders, advisors, attorneys, trustees, or agents of Seller,
or any other person or entity, shall have any personal liability or obligation
whatsoever for obligations entered into by or on behalf of Seller.
Notwithstanding anything to the contrary contained in this Agreement, it is
understood and agreed that none of the employees, directors, officers, members,
partners, managers, principals, consultants, shareholders, advisors, attorneys,
trustees or agents of Purchaser, or any other Person, shall have any personal
liability or obligation whatsoever for any obligations under this Agreement or
under any documents delivered at Closing, and the individual assets of such
parties shall not be subject to any claims of any Person relating to such
obligations. However, the foregoing shall not in any way limit the parties'
obligations and liabilities under this Agreement. The provisions of this Section
13.13 shall survive the Closing or any early termination of this Agreement.

         13.14 No Recording or Notice of Pendency. Seller and Purchaser agree
that neither this Agreement nor any memorandum or notice thereof shall be
recorded. Purchaser agrees (a) not to file any notice of pendency, except in
connection with Purchaser's right to commence an action seeking specific
performance under Section 7.4 of this Agreement, or other instrument or judgment
against the Property or any portion thereof in connection herewith and (b) to
indemnify Seller against all costs, expenses and damages, including without
limitation, reasonable attorneys' fees and disbursements incurred by Seller by
reason of the filing by Purchaser of such notice of pendency or other
instrument. The provisions of this Section shall survive the Closing or any
early termination of this Agreement.

         13.15 Confidentiality; Public Announcements.

                  (a) Purchaser and Seller shall hold the Confidential
Information in confidence, and in connection therewith Purchaser and Seller
shall not show this Agreement or the other Confidential Information to any third
party other than as set forth below. The parties acknowledge that any existing
confidentiality agreement between Seller and Purchaser or any of its affiliates
with respect to the Property shall be terminated as of the date hereof and shall
be of no further force and effect.

                  (b) Notwithstanding the foregoing, Purchaser and Seller may
make the Confidential Information available to their respective employees,
officers and principals and those Disclosure Parties who, with respect to
Purchaser, in Purchaser's sole judgment and, with respect to Seller, in Seller's
sole judgment, need to know such information for the purpose of evaluating the
transactions contemplated hereby. If Purchaser or Seller make the Confidential
Information available to any Disclosure Party, then Purchaser or Seller, as the
case may be, shall inform such Disclosure Party to keep such Confidential
Information strictly confidential in accordance with this Agreement. Purchaser
or Seller, as the case may be, shall be responsible for any violation of this
provision by their respective Disclosure Parties but not for punitive or
consequential damages. In addition, Purchaser or Seller, as the case may be,
shall be entitled to disclose any Confidential Information which (i) was or
becomes generally available to the public other than as a result of disclosure
by the other party or any of its employees, agents, representatives or
consultants to the public or to any third party in violation of this Agreement;
(ii) becomes available to Purchaser or Seller, as the case may be, from a source
other than the

                                       28
<PAGE>

other party or its representatives, provided that Purchaser or Seller, as the
case may be, has no reason to believe (in its reasonable judgment) that such
source is itself bound by any nondisclosure obligation in favor of the other
party; (iii) was rightfully in the possession of Purchaser or Seller, as the
case may be, prior to its receipt from the other party or its representatives;
(iv) Purchaser or Seller, as the case may be, is required to disclose by
Requirement of Law or by any Governmental Entity of competent jurisdiction or to
comply with any applicable securities law or regulations, provided, to the
extent practical, Purchaser or Seller, as the case may be, shall provide the
other party with reasonable prior written notice of such disclosure obligation;
or (v) is disclosed in connection with obtaining the IDA Transfer or the
Approval Order.

shall commence on or about January 1, 2002 (the "Commencement Date") and shall
continue on an "at-will" basis, meaning that either you or the Company may
terminate your employment at any time and for any reason.

      2. Compensation.

Beginning with calendar year 2002, you will also be eligible to participate in
the Company's annual performance-based incentive bonus plan as approved by the
Board solely in its discretion. You expressly acknowledge that you will not be
eligible to receive any bonus from the Company in respect of calendar year 2001,

Company. If you voluntarily terminate your employment or the Company terminates
your employment for cause within one year of the Commencement Date, you shall be
required to reimburse the Company for such Signing Bonus; provided that, the
amount you shall be required to repay the Company shall be reduced 1/12th for

bonus is designated to pay off your Gilead loan.

            (c) Equity Compensation. Subject to approval by the Board, you shall
receive stock options to purchase 25,000 shares of the Company's common stock,

developed or made a sales presentation (or similar offering of services),
located within the Restricted Territory; or

                  (iii) Either individually or on behalf of or through any third
party, directly or indirectly, solicit, entice or persuade or attempt to
solicit, entice or persuade any other employees of or consultants to the company

reason.

            (b) Reasonableness of Restrictions. You further recognize and
acknowledge that (i) the types of employment which are prohibited by this
Section 4 are narrow and reasonable in relation to the skills which represent
your principal salable asset both to the Company and to your other prospective
employers, and (ii) the specific but broad geographical scope of the provisions
of this Section 4 is reasonable, legitimate and fair to you in light of the
Company's need to market its services and sell its products in a large
geographic area in order to have a sufficient customer base to make the
Company's business profitable and in light of the limited restrictions on the
type of employment prohibited herein compared to the types of employment for
which you are qualified to earn your livelihood.

suppliers, licensors, licensees, partners, investors, affiliates or others,
training methods and materials, financial information, sales prospects, client
lists, inventions, or any other scientific, technical, trade or business secret
of the Company or any third party provided to you or the Company under a
condition of confidentiality, provided that Confidential and Proprietary
Information shall not include information that is (1) in the public domain other
than through any fault or act by you, (2) known to you prior to its disclosure
to you in the course of your employment by the Company, or (3) lawfully
disclosed to you by a source other than the Company which source has the legal
right to disclose such information.

discoveries, creations, manuscripts and properties, innovations, improvements,
know-how, inventions, designs, developments, apparatus, techniques, methods,
biological processes, cell lines, laboratory notebooks and formulae which may be
used in the business of the Company, whether patentable, copyrightable or not,
which you may conceive, reduce to practice or develop during your employment

another, or others and whether at the request or upon the suggestion of the
Company, or

otherwise, shall be the sole and exclusive property of the Company, and that you
shall not publish any of the Inventions without the prior written consent of the
Company. You hereby assign to the Company all of your right, title and interest
in and to all of the foregoing. You further represent and agree that to the best
of your knowledge and belief none of the Inventions will violate or infringe

firm or corporation and that you will use your best efforts to prevent any such
violation. You agree that you will fully cooperate with the Company, its
attorneys and agents in the preparation and filing of all papers and other
documents as may be required to perfect the Company's rights in and to any of
such Inventions.

      7. Disclosure to Future Employers. You agree that you will provide, and
that the Company may similarly provide in its discretion, a copy of the
covenants contained in Sections 4, 5 and 6 of this Agreement to any business or
enterprise which you may directly, or indirectly, own, manage, operate, finance,
join, control or in which you participate in the ownership, management,
operation, financing or control, or with which you may be connected as an
officer, director, employee, partner, principal, agent, representative,
consultant or otherwise.

      8. Records. Upon termination of your relationship with the Company, you
shall deliver to the Company any property of the Company which may be in your
possession including products, materials, memoranda, notes, records, reports, or
other documents or photocopies of the same.

      9. No Conflicting Agreements. You hereby represent and warrant that you
have no commitments or obligations inconsistent with this Agreement and you
hereby agree to indemnify and hold the Company harmless against loss, damage,
liability or expense arising from any claim based upon circumstances alleged to
be inconsistent with such representation and warranty.

      10. Other. Based upon financial evaluation of the value in your unvested
Gilead options, OSI will be granting you 25,000 options of OSI common stock.
