escrow,  shall have the right to  conduct,  at its sole cost and  expense,  such
investigations,  studies,  surveys, analyses and tests on and of the Property as
it  shall,  in its  sole  discretion,  determine  are  necessary  or  desirable,
including, without limitation, soil tests, environmental audits and studies, and

determine are necessary or desirable under the circumstances,  provided that (i)
Buyer and any such Buyer  Party  shall only have the right to conduct  soils and
groundwater  tests and borings  regarding  the  environmental  condition  of the
Property  with  the  Seller's  prior  written   consent,   which  shall  not  be
unreasonably  withheld or delayed,  (ii) Buyer  shall  maintain,  or in the case
Buyer  Party is the  entering  party,  cause Buyer  Party to  maintain,  a Three
Million  Dollar  ($3,000,000)  combined,  single  limit,  comprehensive  general

licensed  insurance  company  naming  Seller and  Seller's  property  manager as

Seller  and  the  Property  and  Seller's  affiliates,   members,  subsidiaries,
officers, directors and agents harmless from and against any loss, cost, damage,
or expense (including without limitation,  reasonable  attorneys' fees) incurred
by Seller as a result of property damage,  personal injury, or mechanics' liens,
to the  extent  arising  out of  Buyer's  or Buyer  Party's  inspections  of the
Property and  Improvements.  Without  limiting the  generality of the foregoing,
Buyer agrees to pay Seller,  or cause a Buyer Party to pay Seller,  upon demand,
the cost of repairing and restoring any damage or disturbance which Buyer, Buyer
Party  or  their  respective  agents  or  contractors  cause  to  the  Property.
Notwithstanding  the  foregoing,  Buyer  Party shall have no  liability  for the
discovery of any matters in, on, at, or relating to the Property.  The indemnity
contained in this Section 4(a) shall survive the close of escrow or  termination
of this Agreement. In order to perform the foregoing investigations,  during the
Contingency  Period,  Buyer,  Buyer  Party  (if  applicable),  their  respective
potential lenders, and the agents, contractors,  and employees for said parties,
shall have reasonable access to the Property, all for the purposes of inspecting
the same and  conducting  tests,  inspections,  and analyses  thereon and making
evaluations  thereof,  all at the  Buyer's,  or Buyer  Party's (if  applicable),
expense. In particular,  Buyer and Buyer Party shall be permitted to conduct the
borings,  drillings,  soils tests and  groundwater  tests described on Exhibit N

other borings,  drillings,  soils tests, or groundwater tests on the Property in
connection with the preparation of an environmental  audit or in connection with
any other  inspection  of the  Property  without  the prior  written  reasonable
consent of Seller.  Buyer or Buyer Party, as the case may be, shall schedule and
coordinate all inspections,  including,  without  limitation,  any environmental
tests,  with Seller and shall give Seller at least one (1) business  day's prior
notice of such test.  Seller shall be entitled to have a representative  present
at all times during each such inspection. Seller has made available to Buyer the
documents,  plans,  studies  (environmental  or otherwise) and reports listed on
Exhibit M attached hereto.  Except as expressly  provided to the contrary in the
Seller Certificate or this Agreement, Seller makes no representation or warranty
relating to the  validity of such  information  and Buyer (or Buyer Party as the
case may be) is responsible to verify such  information  at its  discretion.  In
conducting the inspection of the Property,  Buyer shall at all times comply with
all laws and regulations of all applicable governmental  authorities,  and Buyer
shall not contact or have any discussions with any of Seller's employees, agents
or representatives,  or with any contractors  providing services to the Property
unless in each case Buyer  obtains the prior  consent of Seller,  which  consent
shall not be  unreasonably  withheld,  it being agreed that all such contacts or
discussions shall, pending any such approval, be directed to Carl Shannon ((415)
536-1850).

              (b) Termination During Contingency Period.  Buyer may, at any time
during the Contingency  Period,  for any reason or no reason, (i) terminate this
Agreement by delivering to Seller its written notice of termination prior to the
expiration of the Contingency  Period, or (ii) waive its right to terminate this
Agreement by, prior to the expiration of the Contingency Period, (a) waiving its
termination  right in writing  and  delivering  such  waiver to Seller,  and (b)

accordance with the foregoing no later than 5 p.m.  Pacific Time on the last day
of the Contingency  Period, or (2) fails to deposit the Additional  Deposit with
the  Title  Company  no later  than 5 p.m.  Pacific  Time on the last day of the
Contingency Period, then this Agreement shall  automatically  terminate.  In the
event of any automatic  termination  or other  termination  by Buyer pursuant to
this  Section  4(b),  (x) the Initial  Deposit and all other funds  deposited in
escrow by Buyer and all interest  accrued on such funds (less  Buyer's  share of
any escrow and title cancellation fees) shall be returned  immediately to Buyer,
(y) all  documents  deposited  in escrow by Buyer or Seller shall be returned to
the depositing party, and (z) Buyer shall promptly deliver to Seller, at no cost
to Seller,  and without  representation or warranty,  the originals or copies of
all tests,  reports and inspections of the Property,  which do not restrict such

Buyer's  benefit or for Buyer  Party's  benefit  which are in the  possession or
control of Buyer and promptly return to Seller copies of all materials delivered
by Seller to Buyer and shall  destroy  all copies  and  abstracts  thereof,  and
except for this Section 4(b) and the provisions of this Agreement that expressly

further rights or obligations hereunder.

binding  commitment  of  the  Title  Company  to  issue,  on the  Closing  Date,
conditioned  only  upon  payment  of  the  Title  Company's  regularly-scheduled
premium,  the title policy ("Title Policy")  described in the Title  Commitment,
including  the  endorsements  described  in the Title  Commitment,  insuring fee

                   (ii) Subject to Section 8 of this Agreement, there shall have
been no material  adverse change in the condition of the Property or any portion

                   (iii) There are no contracts,  other than the PMC Lease,  the
Permitted  Exceptions,  and any other  agreements  approved in writing by Buyer,
which will affect the  Property or be binding upon Buyer on or after the Closing
Date.

                   (iv) From and after the Contract Date,  Seller has not failed
in any  material  respect to perform the items  described in clauses (i) through
(vi) of Section 5.3(a) below.

                   (v) From and after the Contract Date,  Seller has not removed

                   (vi) The execution,  acknowledgement,  and delivery by Seller
and the owner of the  Adjacent  Property  of an  Amended  and  Restated  Parking
Easement  Agreement in the form  attached  hereto as Exhibit J, the  recordation

subordination  thereto by the holder of any deed of trust or other  foreclosable

Buyer Party (if applicable) of the Reliance Letter.

                   (viii) The  execution  and  delivery  to Buyer of the Closing
Certificate.  Notwithstanding  the foregoing,  if Seller  includes any matter on
Schedule 2 to the  Closing  Certificate  and all  matters  on  Schedule 2 to the
Closing Certificate,  when taken together, constitute a "Material Exception" (as
hereinafter  defined),  Buyer shall have the right to terminate this  Agreement.
Upon any such termination,  the Deposit will be returned by the Title Company to
Buyer (and  Seller  shall so instruct  the Title  Company)  and,  subject to the
provision for reimbursement of expenses under certain circumstances set forth in
this Section  4(c)(viii),  this Agreement  shall  terminate and be of no further
force or  effect,  except  for  those  provisions  that  expressly  survive  the

and Buyer shall  consummate this  transaction in accordance with this Agreement.
If Seller includes any matter on Schedule 2 to the Closing Certificate,  but all

precedent  described in Section  4(c)(ix)  shall  apply,  and (3) subject to the

transaction  without any  abatement  in the  Purchase  Price as a result of that
matter (so long as the  condition  precedent  described  in Section  4(c)(ix) is
satisfied).  Furthermore,  if Buyer  terminates this Agreement  pursuant to this
Section  4(c)(viii)  and a  matter  set  forth  on  Schedule  2 to  the  Closing

request,  shall  pay to  Buyer  an  amount  equal  to all of the  Buyer  Party's
out-of-pocket  costs  incurred in  connection  with or related to the  Property,
including  without  limited to legal  expenses,  non-refundable  loan fees,  and
studies,  inspections and  investigations of the Property during the Contingency
Period,  but in no event to exceed  $250,000.  For the  purposes of this Section
4(c)(viii), the matters set forth on Schedule 2 to the Closing Certificate shall
be deemed a "Material  Exception," if, but only if, all of the matters  included

be expected to result in additional  cost,  expense,  liability and/or damage to
Buyer (after  factoring in all cost of litigating,  resolving,  and/or defending
the  matter,  any  reduction  in the  fair  market  value of the  Property,  any
contingent liability, and the cost of any delay in the lease-up of the Property)
in excess of Five Hundred  Thousand Dollars  ($500,000).  The provisions of this
Section  4(c)(viii) shall survive the close of escrow or the termination of this
Agreement.  In addition,  the  provisions  of this Section  4(c)(viii)  shall be
subject to Section 8 of this Agreement and shall not apply to any events covered
thereunder.

above,  the  delivery  to  Buyer of the WHTS  Modification  Indemnity.  The WHTS
Modification  Indemnity  shall be  subject to the  limitations  set forth in the

and the owner of the Adjacent  Property of the Development  Indemnity  Agreement

Buyer shall use, or shall cause Buyer Party to use, good faith efforts to obtain
the Insurance Policy.

At any time or times on or before the Scheduled  Closing  Date,  Buyer may waive
any of the foregoing  conditions by written notice to Seller. Other than Buyer's

later time as may be required to obtain necessary information for proration,  by
cash payment to the party  yielding a net credit from such  prorations  from the
other party.  Such cash payment  shall be made within ten (10)  business days of
demand  for  payment by the party  entitled  to receive  such  payment.

                   (c) The  provisions  of this  Section  6.6 shall  survive the
close of escrow.

              6.7 Closing Costs.  Seller shall pay (i) the cost of the County of
Santa Clara transfer tax, (ii) the basic CLTA portion (with no  endorsements) of
the title  insurance  premiums  for the title  insurance  described in the Title
Commitment,  (iii) one-half of all escrow fees, and (iv) Seller's legal fees and
costs incurred in connection with the contemplated transaction.  Buyer shall pay
(i)  the  balance  of  the  title  insurance   premium   (including   costs  for
endorsements),  (ii) recording  fees,  (iii)  one-half of all escrow fees,  (iv)
Buyer's  legal  fees and costs  incurred  in  connection  with the  contemplated
transaction,  and (v) all costs and  expenses  incurred in  connection  with any
financing obtained by Buyer,  including without limitation,  loan fees, mortgage
recording  taxes,  financing  costs and lender's legal fees. Any applicable city
transfer  tax shall be shared  equally by Buyer and  Seller.  All other  closing
costs shall be borne by Seller  and/or Buyer in the manner which is customary in
the county where the Land is located. Notwithstanding the foregoing, if close of
escrow  fails to occur as a  consequence  of the  default by a party,  then such
party  shall  pay all  escrow  fees and  cancellation  fees  owing to the  Title
Company.

              6.8 Possession. Right to possession of the Property shall transfer
to Buyer on the Closing Date subject to the PMC Lease.

              6.9 Filing Of Reports.  Title Company shall be solely  responsible
for the  timely  filing of any  reports  or  returns  required  pursuant  to the
provisions  of Section  6045(e) of the  Internal  Revenue  Code of 1986 (and any
similar reports or returns required under any state or local laws) in connection
with the closing of the transaction contemplated in this Agreement.

              6.10 Cooperation.  Without further  consideration,  each of Seller
and Buyer shall execute,  acknowledge and deliver to the other party on or after
the Closing Date any and all other instruments or documents,  and do and perform
any other acts which may be  required  or which the other  party may  reasonably
request in order to fully assign,  transfer and/or convey to Buyer,  and vest in
Buyer, the Property, and each and every part and component thereof.

         7. Liquidated  Damages.  BUYER AND SELLER HEREBY  ACKNOWLEDGE AND AGREE
THAT, IN THE EVENT THE TRANSACTION PROVIDED FOR IN THIS AGREEMENT FAILS DUE TO A
DEFAULT BY BUYER OF AN OBLIGATION TO PURCHASE THE PROPERTY  AFTER (i) ALL OF THE
CONDITIONS TO THE BUYER'S  OBLIGATION  TO PURCHASE THE PROPERTY  SHALL HAVE BEEN
SATISFIED,  OR WAIVED  IN  WRITING  BY BUYER,  AND (ii) THE  SELLER  SHALL  HAVE
PERFORMED,   TENDERED,  OR  OFFERED  TO  TENDER,   PERFORMANCE  OF  ALL  OF  ITS
OBLIGATIONS,  SELLER'S DAMAGES WOULD BE DIFFICULT OR IMPOSSIBLE TO DETERMINE AND
THE AMOUNT OF THE DEPOSIT IS THE PARTIES' BEST AND MOST ACCURATE ESTIMATE OF THE
DAMAGES SELLER WOULD SUFFER. ACCORDINGLY,  THE PARTIES AGREE THAT, IN SUCH EVENT
THE DEPOSIT SHALL BE PAID BY TITLE COMPANY TO SELLER AS LIQUIDATED DAMAGES UNDER
THE  FOREGOING  CONDITIONS,  AND THAT  SUCH  PAYMENT  IS  REASONABLE  UNDER  THE
CIRCUMSTANCES EXISTING AS OF THE DATE OF THIS AGREEMENT.  BUYER AND SELLER AGREE
THAT THE SELLER'S  RIGHT TO RETAIN THE DEPOSIT  SHALL BE THE SOLE AND  EXCLUSIVE
REMEDY  OF  SELLER  IN THE  EVENT OF SUCH A BREACH  OF THIS  AGREEMENT  BY BUYER
FOLLOWING SATISFACTION OF SUCH CONDITIONS.

  BUYER                                             SELLER

         8. Damage And  Destruction;  Condemnation.  Seller  shall  notify Buyer
immediately  of the  occurrence of any damage to or destruction of the Property,
or the  institution or maintenance of any  condemnation  or similar  proceedings
with respect to the Property prior to the Closing Date of which Seller is aware.
In the  event of any  damage  to or  destruction  of the  Property  prior to the
Closing Date for which the cost to repair in the aggregate exceeds $500,000,  or
in  the  event  any  condemnation  or  similar  proceedings  are  instituted  or
maintained  prior to the  Closing  Date,  Buyer  at its  option  either  (i) may
terminate  this  Agreement by written  notice to Seller  prior to the  Scheduled
Closing Date, or (ii) may consummate the purchase  evidenced by this  Agreement.
With  respect  to any  damage to or  destruction  of the  Property  prior to the
Closing  Date for  which  the cost to repair  does not in the  aggregate  exceed
$500,000,  Buyer shall have no right to terminate this Agreement pursuant to the
preceding  sentence,  this Agreement shall continue in accordance with its terms
and the  Purchase  Price shall be reduced by the  Restoration  Funds (as defined
below).  As used herein,  "Restoration  Funds" shall mean an amount equal to the
actual costs and expenses directly and indirectly  related to the restoration of
the  Property,  including  the costs of  permits  less the  actual  proceeds  of
insurance assigned to Buyer at the Closing, but not exceeding the estimated cost
of the restoration as reasonably  determined and agreed upon by Buyer and Seller
based on bids for a guaranteed maximum price contract for the restoration, which
may include  appropriate  contingencies for cost overruns reasonably agreed upon
by Buyer and Seller.  If Buyer and Seller do not reasonably  agree on the amount
of the Restoration  Funds and reasonable  contingencies in connection  therewith
prior to the Closing  Date,  then Buyer shall have the right to  terminate  this
Agreement as described above on or before the Closing Date. If this Agreement is
not  terminated by Buyer pursuant to this Section 8, then (i) Buyer shall accept
possession  of the Property in such  damaged  condition  and/or  subject to such
condemnation  or other  proceeding on the Closing  Date,  (ii) as of the Closing
Date,  Seller  shall  assign to Buyer all  insurance  proceeds  or  condemnation
proceeds  received  or to be  received  by Seller as a result of such  damage or
taking,  and (iii),  if  applicable,  the Purchase Price shall be reduced by the
amount of the  Restoration  Funds.  If this Agreement is so terminated by Buyer,
then Buyer shall be entitled to an immediate return of the Deposit.

         9.  Commissions.  Each party to this  Agreement  warrants  to the other
that,  except to the extent payable solely by the warranting party, no person or
entity can  properly  claim a right to a real  estate  commission,  real  estate
finder's fee, real estate  acquisition  fee or other real estate  brokerage-type
compensation  (collectively,  "Real Estate Compensation") based upon the acts of
that party with respect to the transaction  contemplated by this Agreement,  and
each party hereby agrees to indemnify,  defend and protect the other against and
to hold the other  harmless from any loss,  cost or expense  (including  but not
limited to attorneys'  fees and returned  commissions)  resulting from any claim
for Real Estate Compensation by any person or entity based upon such acts.

         10. General Provisions.

              10.1 Notices.  Any notice  required or permitted to be given under
this Agreement  shall be in writing and (i) personally  delivered,  (ii) sent by
United  States mail,  registered  or certified  mail,  postage  prepaid,  return
receipt  requested,   (iii)  sent  by  Federal  Express  or  similar  nationally
recognized  overnight  courier service,  or (iv) transmitted by facsimile with a
hard copy sent within one (1) business day by any of the foregoing means, and in
all cases  addressed  as follows,  and such notice  shall be deemed to have been

delivery)  at the address  specified  below (or such other  addresses  as may be
specified by notice in the foregoing  manner) as indicated on the return receipt

              10.2 Entire Agreement; No Modifications.  This Agreement, together
with the schedules and exhibits  attached  hereto,  incorporates all agreements,
warranties,  representations  and  understandings  between  the  parties  to the
Agreement with respect to the subject matter hereof and  constitutes  the entire
agreement  of Seller and Buyer  with  respect  to the  purchase  and sale of the
Property.    Any   prior   or   contemporaneous    correspondence,    memoranda,
understandings, offers, negotiations and agreements, oral or written, are merged
herein and replaced in total by this Agreement and the exhibits hereto and shall
be of no further force or effect.  This Agreement may not be modified or amended
except in a writing signed by Seller and Buyer.

              10.3  Time.  Time  is of the  essence  in the  performance  of the
parties' respective obligations set forth in this Agreement.

              10.4 Attorneys' Fees. In the event any action or proceeding at law
or in equity between Buyer and Seller (including an action or proceeding between
Buyer and the  trustee  or debtor in  possession  while  Seller is a debtor in a
proceeding under the Bankruptcy Code (Title 11 of the United States Code) or any
successor  statute to such Code) to enforce or interpret  any  provision of this
Agreement  or to protect  or  establish  any right or remedy of either  Buyer or
Seller hereunder,  the unsuccessful party to such action or proceeding shall pay
to the prevailing party all costs and expenses  including,  without  limitation,
reasonable  attorneys'  and  paralegals'  fees and  expenses,  incurred  by such
prevailing  party,  in such action or proceeding and in any appeal in connection
therewith,  whether or not such action,  proceeding  or appeal is  prosecuted to
judgment or other final  determination,  together with all costs of  enforcement
and/or collection of any judgment or other relief.

              10.5 Specific  Performance.  The parties understand and agree that
the  Property  is  unique  and for that  reason,  among  others,  Buyer  will be
irreparably  damaged  in the  event  that  this  Agreement  is not  specifically
enforced.  Accordingly,  in the  event of any  breach or  default  in or of this
Agreement or any of the warranties, terms or provisions hereof by Seller, Buyer,
in addition to a claim for damages for such breach or default (subject, however,
to the  limitations  set forth in Section  5.1),  and in  addition  and  without
prejudice to any right or remedy  available at law or in equity,  shall have the
right  (i) to  seek to  obtain  specific  performance  of  Seller's  obligations
hereunder,  provided that any action for specific performance shall be commenced
within  sixty (60) days after such  default.  If Buyer  elects to seek  specific
performance  of this  Agreement,  then as a condition  precedent to any suit for
specific  performance,  Buyer shall on or before the Closing Date, time being of
the essence, fully perform all of its obligations hereunder which are capable of
being performed  (other than the payment of the Purchase  Price,  which shall be
paid as and when required by the court in the suit for specific performance).

              10.6  Successors And Assigns.  Except as permitted by this Section
10.6,  this  Agreement  may not be assigned by Seller or Buyer without the prior
written consent of the other party which may be granted or withheld by the other
party in its sole discretion. Subject to the foregoing provision, this Agreement
shall inure to the benefit of and be binding upon the parties to this  Agreement
and their  respective  successors  and  assigns.  Buyer  shall have the right to
assign its rights and obligations under this Agreement to an affiliate of Buyer,
provided  that  the  assignee  assumes  for  Seller's  benefit  all  of  Buyer's
obligations  hereunder.  For the purposes of this Section  10.6,  "affiliate  of
Buyer" shall mean an entity  controlling,  controlled by or under common control
with Buyer. "Control" shall mean the possession,  directly or indirectly, of the
power to direct the  management and policies of an entity,  whether  through the
ownership of voting securities, by contract or otherwise.

              10.7  Counterparts.  This Agreement may be executed in one or more
counterparts  and each such counterpart  shall be deemed to be an original;  all
counterparts so executed shall constitute one instrument and shall be binding on
all of the parties to this Agreement notwithstanding that all of the parties are
not signatories to the same counterpart.

              10.8  Construction.  This  Agreement  shall  be  governed  by  and
construed  under the laws of the State of  California.  The parties  acknowledge
that each party and its counsel have  reviewed and revised  this  Agreement  and
that no rule of  construction  to the  effect  that  any  ambiguities  are to be
resolved against the drafting party shall be employed in the  interpretation  of
this  Agreement or any schedules or exhibits to it or any document  executed and
delivered by either party in  connection  with this  Agreement.  All captions in
this   Agreement  are  for  reference   only  and  shall  not  be  used  in  the
interpretation  of this Agreement or any related  document.  If any provision of
this  Agreement  shall  be  determined  to be  illegal  or  unenforceable,  such
determination  shall not affect any other  provision of this  Agreement  and all
such other provisions shall remain in full force and effect.

              10.9  Confidentiality.  Seller shall keep all information obtained
from or about Buyer or the transaction  contemplated by this Agreement  strictly
confidential  and will not disclose any such  information to any other person or
entity   without  first   obtaining   the  prior   written   consent  of  Buyer.
Notwithstanding anything to the contrary contained in this Agreement,  Buyer and
Buyer's  Agents and Seller and Seller's  Agents may  disclose the tax  treatment
(i.e.,  the  purported  or  claimed  Federal  income tax  treatment)  or the tax
structure (i.e., any fact that may be relevant to understanding  such treatment)
of the transaction contemplated by this Agreement, and all materials of any kind
(including  opinions or other tax analyses) provided by Seller to Buyer relating
to such tax treatment and tax structure.  Furthermore,  each of Buyer and Seller
acknowledges  and agrees  that it has not made or  provided a  statement  to the
other  party with  respect to the tax  consequences  for the other  party of the
transactions contemplated by the Purchase Agreement.

              10.10 Exculpation. Buyer agrees that it does not have and will not
have any  claims or  causes  of action  against  any  disclosed  or  undisclosed
officer, director, employee, trustee,  shareholder,  partner, member, principal,
parent, subsidiary or other affiliate of Seller, including,  without limitation,
Tishman  Speyer  Properties,  L.P.  and  Goldman,  Sachs & Co., or any  officer,
director,  employee, trustee,  shareholder,  member, partner or principal of any
such   parent,   subsidiary   or  other   affiliate   (collectively,   "Seller's
Affiliates"),   arising  out  of  with  this   Agreement  or  the   transactions
contemplated  hereby.  Buyer  agrees to look solely to Seller and its assets for
the satisfaction of any liability or obligation  arising under this Agreement or
the  transactions  contemplated  hereby,  or for the  performance  of any of the
covenants,  warranties or other agreements  contained herein, and further agrees
not to sue or otherwise seek to enforce any personal  obligation  against any of
Seller's Affiliates with respect to any matters arising out of this Agreement or
the  transactions  contemplated  hereby.  The  provisions of this Section 10.10,
however,  shall not apply to Tishman  Speyer/Travelers Real Estate Venture, L.P.
and Whitehall  Street Real Estate  Limited  Partnership  IX  (collectively,  the
"Members")  to the extent of the amount any of the Members has received from the
proceeds  of the  transactions  which is the subject of this  Agreement,  if the
remaining  funds  available to Seller to satisfy the  obligations  of the Seller
pursuant to this Agreement or the  transactions  contemplated  hereby are not at
least  equal to Five  Million  Dollars  ($5,000,000)  or such  lower  amount  of
liability or potential  liability as the Seller may have under such  agreements.
The  provisions  of this Section  10.10 shall  survive the  termination  of this
Agreement  and the Closing.  This Section 10.10 will not apply to the parties to
the Parking Easement or the Development  Indemnity  Agreement to the extent such
claim or cause of action relates solely to the Parking Easement Agreement or the
Development Indemnity Agreement, as applicable.


         IN WITNESS WHEREOF, Buyer and Seller have executed this Agreement as of
the date and year first written above:
