          Escrow an additional sum of cash in the amount of Fifty Thousand
          Dollars ($50,000), provided that Buyer does not elect to terminate
          this Agreement; and

                   (iii)  Buyer shall deposit into Escrow the balance of the
          Purchase Price, as well as all sums necessary to pay Buyer's costs,
          expenses and prorations in connection with this transaction at least

              (b)  So much of the cash sums as have actually been deposited into
     Escrow pursuant to Sections 2(a)(i) and 2(a)(ii) shall sometimes be
     referred to herein as the "Deposit." The Deposit shall be placed in an
     interest-bearing account by Escrow Holder at a financial institution whose
     deposits are federally insured upon terms acceptable to Buyer. All interest
     which accrues on the Deposit shall be considered a part of the Deposit.
     Subject to the provisions of Sections 13 and 14 below, the Deposit shall be
     applied as follows: (i) in the event that a Close of Escrow occurs, the
     entire amount of the Deposit shall be credited against the Purchase Price
     concurrently with the Close of Escrow; (ii) in the event that this
     Agreement is terminated pursuant to Section 3(c) below, the Deposit shall
     be refunded to Buyer in accordance with the terms of Section 3(c); or (iii)
     in the event of either a default by Buyer as provided in Section 15 below
     or the approval and/or waiver of all contingencies under the terms of
     Section 3 below, the Deposit shall be released to Seller, shall be non-
     refundable to Buyer and shall constitute the liquidated damages of Seller
     pursuant to Section 15 below. In the event the Deposit is released to
     Seller pursuant to the preceding sentence but thereafter Seller defaults
     under this Agreement or the Title Company refuses or is unable to issue the
     Title Policy, the Deposit shall be returned to Buyer.

          3.  Contingencies.  Buyer's obligation to purchase the Property and
              -------------
the remainder of Buyer's obligations under this Agreement shall be subject to
its approval, deemed approval or waiver of the following contingencies within
the time periods indicated below:

              (a)  Title.
                   -----

                   (i)    Buyer shall have until May 15, 2000 to review and
          approve a preliminary title report on the Property (the "PTR")
          prepared by First American Title Insurance Company (the "Title
          Company"), together with legible copies of all documents (the
          "Exception Documents") relating to the title exceptions referred to in
          the PTR. In the event Buyer approves the PTR, all title matters set
          forth in the PTR and all of the Title Company's standard printed
          exceptions to coverage shall constitute the "Permitted Exceptions." In
          the event Buyer disapproves any title exception(s) contained in the
          PTR, then this Agreement shall terminate in accordance with Section
          3(c) unless Seller agrees in writing that prior to or concurrently
          with the Close of Escrow, Seller will remove the disapproved
          exception(s) from title. If Seller so agrees in writing, all title
          matters set forth in

<PAGE>

          the PTR except for the disapproved exception(s), and all of the Title
          Company's standard printed exceptions to coverage, shall be considered
          Permitted Exceptions. Notwithstanding the foregoing, Buyer hereby
          disapproves all monetary liens, and Seller hereby agrees to remove
          monetary liens prior to the Close of Escrow.

                   (ii)   If the Title Company, prior to the Close of Escrow,
          discloses to Buyer a new exception, or materially amends any exception
          previously approved by Buyer, then Buyer shall have five (5) business
          days from its receipt of such disclosure, together with legible copies
          of all documents mentioned in such disclosure, to disapprove the same
          by written notice to Seller; provided, however, that Buyer may
          disapprove such new or amended exception only if such new or amended
          exception materially and adversely affects Buyer's ability to utilize
          the Property for Buyer's intended purpose or diminishes the value of
          the Property. Buyer's failure to so notify Seller shall be deemed to
          mean that such new or amended exceptions are not acceptable to Buyer,
          in which event this Agreement shall terminate and Buyer shall be
          entitled to a refund of the Deposit.

              (b)  Documents to be Obtained and Determinations to be Made by

              pertaining to real estate taxes or assessments applicable to the
              Property (collectively, the "Tax Bills"). Seller shall promptly
              deliver to Buyer a copy of any such Tax Bills received by Seller
              after the date hereof even if received after the Close of Escrow;

                        (C)  The results of a physical inspection of the
              Property, including without limitation, any and all soils,
              geologic, hydrology, seismic, environmental, engineering,
              endangered species, archeological, architectural or other
              inspections, studies or investigations which Buyer deems to be

                        (D)  A copy of the existing Phase I Environmental
              Assessment Report relating to the Property which Seller will
              provide to Buyer, without representation or warranty as to truth,
              accuracy or completeness, upon the Opening of Escrow;
<PAGE>

                        (E)  All existing subdivision, zoning, land use
              entitlements or permit requirements (including without limitation
              water permits) applicable to the Property or Buyer's intended use
              or development thereof;

                        (F)  Such feasibility studies as Buyer deems advisable;
              and

                        (G)  The results of Buyer's review of the construction
              contracts, warranties, and plans and specifications pursuant to
              which the Improvements have been constructed.

                 (ii)   Documents.  Seller will use best efforts to deliver to
                        ---------
     Buyer or its counsel a preliminary title report with underlying documents
     and Seller's non-proprietary and non-confidential records relating to the
     Property, including contracts, plans, studies, reports and other items
     specified in Section 3(b)(i), if any, on or before April 18, 2000. Seller
     represents that all documents in its possession or control listed in
     Section 3(b)(i) will be delivered to Buyer pursuant to the preceding
     sentence. Buyer agrees that any information relating to Seller's costs of
     construction is proprietary and will be redacted from any documents
     (including without limitation, the construction contract) prior to delivery
     to Buyer. Buyer acknowledges and agrees that all documents made available
     by Seller are for informational purposes only, that Seller makes no
     representation or warranty (nor shall any representation or warranty be
     deemed made by Seller) with respect to the truth, accuracy or completeness
     of any matters set forth in such documents, except that Seller represents
     that to Seller's actual knowledge, all copies of documents delivered to
     Buyer are true and correct copies of the originals. Buyer further
     acknowledges and agrees that it is not relying on any information contained
     in such documents and, instead, is relying on its own investigation of the
     Property and related matters as more particularly set forth below in
     Section 8(b).

                 (iii)  Financing.  Buyer shall have until May 15, 2000 to
                        ---------
     satisfy itself as to the availability of financing for the purchase of the
     Property on terms and conditions acceptable to Buyer. At the request of
     Buyer, this contingency may be extended until May 31, 2000, if (A) Buyer
     has in good faith diligently attempted to arrange its loan for the
     acquisition of the Property, and (B) Buyer's lender has not yet finished
     its underwriting to the extent such underwriting relates to the Property
     and not to Buyer.

                 (iv)   Natural Hazard Disclosure.  Within ten (10) calendar
                        -------------------------
     days after Opening of Escrow, Seller shall provide Buyer with a Natural
     Hazard Disclosure Statement with respect to the Property (the "Natural
     Hazard Report") prepared by a commercial entity specializing in such
     services, in order to comply with the natural hazard disclosure
     requirements of the State of California. Seller has made no independent
     inquiry with regard to the matters set forth in the Natural Hazard Report,
     and is exclusively relying on the expertise of
<PAGE>

          the party preparing the Natural Hazard Report. Seller shall have no
          liability to Buyer with respect to any inaccuracy contained in the
          Natural Hazard Report.

               (c)  Conditions Precedent.  The approval or waiver of all
                    --------------------
     contingencies set forth herein within the time period specified in this
     Section 3 is a condition precedent to the Close of Escrow. Buyer may
     approve or disapprove any or all of the documents, materials, items and
     matters identified in this Section 3 in its reasonable discretion. If Buyer
     timely disapproves or is deemed to disapprove any contingency as set forth
     in this Section 3, this Agreement and Escrow shall be terminated, unless
     within ten (10) business days after Seller receives from Buyer written
     notice of such disapproval Seller either satisfies such contingency or
     agrees to satisfy such contingency prior to the Close of Escrow. In the
     event this Agreement and Escrow are terminated pursuant to this Section
     3(c), the Deposit shall be returned to Buyer minus Buyer's share of Escrow
     cancellation charges as provided in Section 5(e) below, and all documents
     deposited into Escrow by either party shall be returned to the party which
     deposited the same.

               (d)  Deemed Disapproval.  The failure by Buyer to approve in
                    ------------------
     writing any of the documents, materials, items or matters referred to in
     this Section 3 within the time period provided herein, shall be deemed
     disapproval by Buyer of such documents, materials, items or matters as to
     which such notice of approval has not been given. Buyer may waive any of
     the foregoing contingencies by the delivery of written notice thereof to
     Seller and Escrow Holder.

               (e)  Release of Deposit.  Upon approval and/or the waiver of all
                    ------------------
     of the foregoing contingencies by Buyer, and following Seller's deposit of
     the Grant Deed into Escrow, the Deposit shall be released to Seller by
     Escrow Holder without any further instruction, and shall be nonrefundable
     to Buyer except in the event of a default by Seller or the Title Company's
     failure to issue the Title Policy.

               (f)  Seller's Right to Studies.  If Escrow fails to close for any
                    -------------------------
     reason other than the breach of this Agreement by Seller, Buyer shall
     immediately deliver to Seller and Seller shall be entitled to retain, at no
     cost or expense to Seller, all layouts, surveys, environmental audits and
     other reports, investigations, test results and information obtained by
     Buyer with respect to the Property (or any part thereof), and, to the
     extent of Buyer's rights therein, Seller shall be authorized to use and
     distribute any and all such documentation and information as it shall elect
     in its sole and absolute discretion, but without representation or warranty
     by Buyer whatsoever.

     diligently attempted to arrange its loan for the acquisition of the
     Property, and (ii) Buyer's lender is not yet prepared to fund such loan.

title to the Property, and therefore responsible for the expenses thereof, for
the entire day upon which the Close of Escrow occurs.

     7.   Title.
          -----

          (a)   Possession. Buyer shall be placed in possession of the Property

                --------------
the cost of the Title Policy and the cost of any and all title endorsements
which are used for title curative purposes under Section 3. Buyer may obtain, in
lieu of the Title Policy, an ALTA Extended Coverage policy of title insurance
(the "ALTA Policy") issued by the Title Company with liability in the amount of
the Purchase Price; provided, however,
                    --------  -------
<PAGE>

     that in such event Buyer shall be solely responsible for any difference in
     premium or charge between the Title Policy and the ALTA Policy and for all
     survey and other costs associated with such ALTA Policy, and, provided
                                                                   --------
     further, Buyer's election to obtain an ALTA Policy shall in no way
     -------
     extend the title review contingency period set forth in Section 3(a).

     8.   Representations, Warranties and Covenants of Buyer.  Buyer hereby
          --------------------------------------------------
represents, warrants and covenants to Seller that the following matters are true
and correct as of the execution of this Agreement and also will be true and
correct as of the Close of Escrow:

          (a) This Agreement and all the documents to be executed and delivered
     by Buyer to Seller pursuant to the terms of this Agreement, (i) have been
     or will be duly authorized, executed and delivered by Buyer, (ii) are or
     will be legal, valid and binding obligations of Buyer as of the date of
     their respective executions, (iii) are or will be enforceable 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 rights of contracting parties
     generally), and (iv) do not, and will not, at the Close of Escrow, violate
     any provisions of any agreement to which any of the individuals or entities
     comprising Buyer is a party.

          (b) Buyer hereby agrees and acknowledges that it is buying the
     Property on an "AS-IS" basis; that it has made or will have made its own
     investigations and inspections of the Property, including, without
     limitation, the physical aspects of the Property; that in connection with
     its investigations and inspections of the Property it contracted or had the
     opportunity to contract with certain advisors and consultants, including,
     but not limited to, environmental consultants, engineers, architects and
     geologists, to conduct such environmental, architectural, geological and
     other inspections of the Property as Buyer deemed to be necessary; that it
     has approved the reports of such entities; that it is relying solely on
     such entities' reports and its own investigations as to the Property, its
     condition and other characteristics; that, except for the representations
     and warranties set forth in Section 9, it is not relying on any
     representations or warranties of Seller regarding the Property or any
     portion thereof or any matter related thereto; and that, except for the
     representations and warranties set forth in Section 9, Buyer is not making
     the purchase in reliance upon any statements or representations, express or
     implied, made by Seller or its agents or brokers, as to the condition of or
     characteristics of the Property, its fitness for use for any particular
     purpose, or the Property's compliance with any zoning or other rules,
     regulations, laws or statutes applicable to the Property, or the uses
     permitted on or the development requirements or any other matters relating
     to the Property. Seller has no liability nor responsibility to Buyer in
     connection with the matters set forth in this Section 8(b), including,
     without limitation, any liability for Seller's negligence or under any
     laws, rules, regulations or ordinances regulating the environment,
     hazardous materials, or human health and safety, or any latent or patent
     defects. Nothing set forth in this Section 8(b) or elsewhere in this
     Agreement shall be construed as a waiver by Buyer of any rights or remedies
     against any person or entity other than Seller and its principals.
<PAGE>

     9.   Representations, Warranties and Covenants of Seller.  Seller hereby
          ---------------------------------------------------
represents, warrants and covenants to Buyer that the following matters are true
and correct as of the execution of this Agreement and will also be true and
correct as of the Close of Escrow:

          (a)   Seller is a limited liability company duly formed, validly
     existing and in good standing under the laws of the State of California.

          (b)   This Agreement and all the documents and items to be executed
     and delivered by Seller to Buyer pursuant to the terms of this Agreement,
     (i) have been or will be duly authorized, executed and delivered by Seller,
     (ii) are or will be legal, valid and binding obligations of Seller as of
     the date of their respective executions, (iii) are or will be enforceable
     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 rights of contracting
     parties generally), and (iv) do not and will not, at the Close of Escrow,
     violate any provisions of any agreement to which Seller is a party.

          (c)   To Seller's actual knowledge, and except as otherwise disclosed
     to Buyer in writing, Seller has not received from any third party
     (including any federal, state or municipal governmental agency or
     authority) written request for information, written notices of claim,
     demand letters, or other written notification that it is or may be
     potentially responsible with respect to any investigation or clean-up of
     hazardous substances (including asbestos) released at the Property.

          (d)   To Seller's actual knowledge, and except as otherwise disclosed
     to Buyer in writing, no condemnation, eminent domain, zoning or other land-
     use regulation proceeding or any other actions, suits or proceedings are
     pending or threatened against the Property, nor has Seller any knowledge of
     any assessments affecting the Property other than as set forth in the PTR.

          (e)   To Seller's actual knowledge, and except as otherwise disclosed
     to Buyer in writing, there are no violations of any covenants, conditions
     or restrictions applicable to the Property, and Seller has received no
     written notice or complaint with respect to any such violation or alleged
     violation.

          (f)   To Seller's actual knowledge, and except as disclosed to Buyer
     in writing, there are no leases or tenancy agreements affecting the
     Property or any portion thereof.

     10.  Intentionally Deleted.
          ---------------------

     11.  Limitation on Enforcement of Rights. Buyer, by completing its
          -----------------------------------
acquisition of the Property, shal be deemed to have waived any breaches or
defaults of Seller of which Buyer had actual knowledge prior to the Close of
Escrow.

     12.  Right to Enter Property.  Commencing on the Opening of Escrow, and
          -----------------------
continuing thereafter until this Agreement has been terminated, Buyer and its
agents shall have the right, at Buyer's sole cost and expense, and upon two (2)
days' prior written notice to Seller
<PAGE>

(which notice shall contain a certificate of the liability insurance policy
described below), to enter onto the Property at reasonable times and in a
reasonable manner for the purpose of making such non-invasive and non-
destructive tests and inspections as Buyer deems necessary in connection with
this Agreement. Buyer shall maintain liability insurance coverage applicable to
such activities with coverage in an amount of One Million Dollars ($1,000,000)
per occurrence and issued by an insurer reasonably acceptable to Seller. Such
policy shall name Seller as an additional insured and shall provide that there
shall not be any cancellation or reduction in coverage without thirty (30) days'
prior written notice to Seller at the address set forth in Section 19. After
making such tests and inspections, Buyer shall restore the Property to its
condition prior to such tests and inspections. Buyer hereby agrees to indemnify,
defend, protect and hold Seller harmless from and against any loss, liability,
claim, damage, cost or expense (including attorneys' fees) in connection with
such tests and inspections.

     13.  Destruction of Improvements.  If prior to the Close of Escrow the
          ---------------------------
Improvements are damaged or destroyed, whether by fire or other casualty, then
Seller shall promptly notify Buyer of such damage or destruction and the cost to
repair the same, as reasonably estimated by Seller.  In the event such estimated
cost is in excess of Fifty Thousand Dollars ($50,000), Buyer may terminate the
Escrow and this Agreement by giving Seller written notice of its intent to do so
within five (5) business days after the date Buyer receives actual notice of
said damage or destruction and the estimated cost to repair.  On such
termination, neither party shall have any further rights or obligations
hereunder, and all funds deposited by Buyer into Escrow or released to Seller
(less Buyer's share of Escrow fees theretofore incurred and one-half of the cost
of the PTR), shall be returned to Buyer.  In the event such estimated cost of
repair is Fifty Thousand Dollars ($50,000) or less, or in the event Buyer elects
not to terminate this Agreement, then the Escrow and this Agreement shall remain
in full force and effect and Seller shall assign to Buyer, as a condition
precedent to the Close of Escrow, all of Seller's rights, title and interest in
and to any insurance proceeds or claims therefor with respect to such damage or
destruction.  Additionally, in such latter case, Seller shall pay to Buyer, by
way of a credit against the Purchase Price, an amount equal to any deductible
amount applicable to such damage or destruction under any casualty insurance
coverage maintained by Seller with respect to the Property.

     14. Loss by Condemnation. In the event that prior to the Close of Escrow,
         --------------------
the Property, or any substantial part thereof, is subject to a taking by a
public authority, then Buyer shall have the right, exercisable by giving notice
to Seller within fifteen (15) days after receiving written notice of such
taking, either (a) to terminate this Agreement and obtain a refund of the
Deposit, in which case neither party shall have any further rights or
obligations hereunder, except that Buyer and Seller shall each be responsible
for one-half of any title or Escrow cancellation fee, or (b) to accept the
Property in its then condition and proceed to close this transaction, and to
receive an assignment of all of Seller's rights to any condemnation awards
payable by reason of such taking. If Buyer elects to proceed under clause (b)
above, Seller shall not compromise, settle or adjust any claims to such awards
without Buyer's prior written consent, which consent shall not be unreasonably
withheld. Seller agrees to give Buyer prompt notice of any taking of the
Property promptly after Seller receives notice of the same.
<PAGE>

     15.  Default of Buyer.  IN THE EVENT BUYER DEFAULTS IN ITS OBLIGATION TO
          ----------------
CLOSE THE PURCHASE OF THE PROPERTY IN ACCORDANCE WITH THIS AGREEMENT, THE
DEPOSIT SHALL BE RETAINED BY SELLER AS LIQUIDATED DAMAGES WHICH SHALL BE
SELLER'S SOLE REMEDY HEREUNDER. THE PARTIES HERETO EXPRESSLY AGREE AND
ACKNOWLEDGE THAT SELLER'S ACTUAL DAMAGES IN THE EVENT OF A DEFAULT BY BUYER
WOULD BE EXTREMELY DIFFICULT OR IMPRACTICABLE TO ASCERTAIN AND THAT THE AMOUNT
OF THE DEPOSIT REPRESENTS THE PARTIES' REASONABLE ESTIMATE OF SUCH DAMAGES. THIS
SECTION 15 APPLIES ONLY TO A DEFAULT OF BUYER IN ITS OBLIGATION TO CLOSE THE
PURCHASE OF THE PROPERTY AND IN NO WAY LIMITS BUYER'S POTENTIAL LIABILITY FOR
ATTORNEYS' FEES PURSUANT TO SECTION 20(B) OR FOR INDEMNITY OBLIGATIONS SET FORTH
IN THIS AGREEMENT.

                    SELLER'S INITIALS:  ______    BUYER'S INITIALS:  ______

     16.  Assignment of Contracts.  Upon the Close of Escrow, Seller shall be
          -----------------------
deemed to have assigned without warranty to Buyer all of Seller's right, title
and interest in and to all assignable contracts, warranties, guaranties, plans,
specifications and architect's, engineer's and other consultant's reports
relating to the Property or the construction of the Improvements. Seller shall
deliver all such documents to Buyer concurrently with the Close of Escrow. Buyer
is not required to assume any obligations under any such documents.

     17.  Buyer's Remedies. Buyer and Seller agree that if the sale
          ----------------
contemplated by this Agreement is not completed as provided herein solely by
reason of a material default of Seller or failure of the Title Company to issue
the Title Policy, Buyer shall be entitled to terminate this Agreement and to
obtain the return of the Deposit with interest at the rate of ten percent (10%)
per annum from the date the Deposit is released from Escrow to Seller. Buyer
does hereby specifically waive any right to pursue any other remedy at law or
equity for such default of Seller.

     18.  Broker's Commission.  In connection with the transaction contemplated
          -------------------
by this Agreement, at the Close of Escrow, Seller shall pay a brokers'
commission pursuant to a separate agreement which commission shall be split
between CB Richard Ellis, Inc. and Told Partners. With the exception of such
commission, Buyer and Seller each represents to the other that it has not
entered into any agreement or incurred any obligation which might result in the
obligation to pay a sales or brokerage commission or finder's fee with respect
to this transaction. Buyer and Seller each agrees to indemnify, defend, protect
and hold the other harmless from and against any and all losses, claims,
damages, costs or expenses (including attorneys' fees) which the other may incur
as a result of any claim made by any person to a right to a sales or brokerage
commission or finder's fee in connection with this transaction to the extent
such claim is based, or purportedly based, on the acts or omissions of Seller or
Buyer, as the case may be. The obligations of Buyer and Seller under this
Section 18 shall survive the Close of Escrow.

     19.  Notices.  All notices required or permitted by this Agreement must be
          -------
in writing and shall be deemed to have been duly given when personally
delivered, twenty-four

          20.  Miscellaneous Provisions.
               ------------------------

               (a)  Incorporation of Prior Agreements.  This Agreement contains
                    ---------------------------------
     the entire understanding of Buyer and Seller with respect to the subject
     matter hereof, and supersedes all prior or contemporaneous written or oral
     agreements and understandings between the parties hereto pertaining to any
     such matter. No provision of this Agreement may be amended, modified or
     supplemented or added to except by an agreement in writing, expressly
     stating that such agreement is an amendment of this Agreement, signed by
     the parties to this Agreement or their respective successors in interest.

               (b)  Attorneys' Fees.  If either party commences an action
                    ---------------
     against the other to interpret or enforce any of the terms of this
     Agreement or because of the breach by the other party of any of the terms
     hereof, the losing party shall pay to the prevailing party reasonable
     attorneys' fees, costs and expenses incurred in connection with the
     prosecution or defense of such action, whether or not the action is
     prosecuted to a final judgment. For the purpose of this Agreement, the
     terms "attorneys' fees" or "attorneys' fees and costs" shall mean the fees
     and expenses of counsel to the parties hereto, which
<PAGE>

may include printing, photostating, duplicating and other expenses, air freight
charges, and fees billed for law clerks, paralegals, librarians and others not
admitted to the bar but performing services under the supervision of an
attorney. The terms "attorneys' fees" or "attorneys' fees and costs" shall also
include, without limitation, all such fees and expenses incurred with respect to
appeals, arbitrations and bankruptcy proceedings, and whether or not any action
or proceeding is brought with respect to the matter for which said fees and
expenses were incurred. The term "attorney" shall have the same meaning as the
term "counsel."

     (c)  Time is of the Essence.  Time is of the essence of this Agreement.
          ----------------------

     (d)  Successors and Assigns.  This Agreement shall be binding upon and
          ----------------------
inure to the benefit of each of the parties hereto and to their respective
transferees, successors and assigns. Notwithstanding the foregoing, Buyer shall
have no right to assign or transfer any of Buyer's rights or responsibilities
hereunder to any person or entity without Seller's prior written consent, which
may be given or withheld in Seller's sole and absolute discretion; provided,
however that Seller hereby consents to an assignment of this Agreement by Buyer
to any entity controlling, controlled by or under common control with Buyer.

     (e)  California Law; Choice of Forum.  This Agreement shall be construed in
          -------------------------------
accordance with and governed by the internal laws of the State of California,
without giving effect to any "conflict of law" rules of such state. Buyer and
Seller each acknowledge and agree that the Superior Court of the State of
California in and for the County of Orange and the associated appellate courts
shall have exclusive jurisdiction to hear and decide any dispute, controversy or
litigation regarding the enforceability or validity of this Agreement or any
portion thereof.

     (f)  Counterparts.  This Agreement may be executed in any number of
          ------------
counterparts, each of which shall be deemed an original, but all of which, when
taken together, shall constitute one and the same instrument.

     (g)  Interpretation.  Wherever possible, each provision of this Agreement
          --------------
shall be interpreted in such a manner as to be valid under applicable law, but,
if any provision of this Agreement shall be invalid or prohibited thereunder,
such invalidity or prohibition shall be construed as if such invalid or
prohibited provision had not been inserted herein and shall not affect the
remainder of such provision or the remaining provisions of this Agreement.
Section headings of this Agreement are solely for convenience of reference and
shall not govern the interpretation of any of the provisions of this Agreement.
Only those obligations and liabilities expressly stated herein to survive the
Close of Escrow shall survive the Close of Escrow.

     (h)  Construction.  The language in all parts of this Agreement shall be
          ------------
in all cases construed simply according to its fair meaning and not strictly
against the party who drafted such language.

     (i)  Exhibits.  All Exhibits attached hereto are incorporated herein by
          --------
reference and made a part hereof for all purposes.
<PAGE>

              (j)  No Recordation.  This Agreement shall not be recorded or
                   --------------
          filed in the public records of any jurisdiction by either party. Any
          attempt to do so shall be a breach of this Agreement.

              (k)  Business Days.  Unless "business day" is specified, the term
                   -------------
          "day" means a calendar day. Nevertheless, whenever action must be
          taken under this Agreement during a certain period of time or by a
          certain date that ends or occurs on a day which is not a business day,
          the time for performance shall be extended to the next business day.
          The term "business day" means any day other than a Saturday, Sunday or
          Federal or State of California holiday.

          21. Confidentiality.
              ---------------

              (a)  In connection with the transaction contemplated herein,
          Seller will be delivering or otherwise making available to Buyer
          information, documents and other materials related to the Property,
          which may include, without limitation, those documents and materials
          referred to in Section 3(b) herein (collectively, the "Information").
          The existence of this Agreement and the terms contained herein are
          considered a part of the Information for purposes of this
          confidentiality provision. Without Seller's prior written consent,
          Buyer agrees not to disclose prior to the Close of Escrow any
          Information except (i) to Buyer's auditors, counsel or professional
          advisors to whom it is necessary to show the Information, each of
          which shall be informed by Buyer of the confidential nature of the
          Information; and (ii) in any statement or testimony pursuant to a
          subpoena or order by any court, governmental body or other agency
          asserting jurisdiction over Buyer, or to comply with Buyer's
          disclosure obligations as a public company, or as may otherwise be
          required by law (provided that Buyer shall give Seller notice of the
          disclosure permitted by this clause (ii) unless such notice is
          prohibited by the subpoena, order or law).

              (b)  In the event this Agreement is terminated for any reason
          prior to the Close of Escrow, Buyer will, upon demand, return to
          Seller all documents or other written material received from Seller
          and all copies thereof made by Buyer which contain the Information
          which have not been properly disposed of by Buyer.

          22. Document Not an Offer.  The submission of this document to Buyer
              ---------------------
by Seller shall not constitute an offer by Seller to sell the Property on the
terms set forth herein or on any other terms. Buyer expressly acknowledges and
agrees that Seller shall not be bound by any of the terms of this Agreement
until Seller has executed this Agreement and delivered it to Escrow Holder.

6.   CONFIDENTIALITY

     6.1  During the term of this Agreement, both parties may have access to
          certain non-public information of GoTo.com, which information a
          reasonable person would consider confidential or which is marked as
          "confidential" or "proprietary" by either party ("Confidential
          Information"). Confidential Information does not include information
          that is generally known and available, or in the public domain through

          Confidential Information to any third parties, (ii) not to use any
          Confidential Information for any purposes except to carry out its
          rights and responsibilities under this Agreement and (iii) to keep the

          the other party uses to protect its own confidential information, as
          long as it uses at least reasonable care. Both parties acknowledges
          and agrees that due to the unique nature of the Confidential
          Information, there can be no adequate remedy at law for any breach of
          its obligations hereunder, that any such breach may allow one party or
          third parties to unfairly compete with the other party resulting in
          irreparable harm to that party and, therefore, that upon any such
          breach or threat thereof, the non-breaching party shall be entitled to
          injunctions and other appropriate equitable relief in addition to
          whatever remedies it may have at law. In addition, if the non-
          breaching party prevails in any legal dispute hereunder, it shall be
          entitled to collect its reasonable attorneys' fees and expenses. The
          sole jurisdiction and venue for actions

     8.1  Term. The term of this Agreement (the "Term") shall commence on the
          ----
          Effective Date and shall continue in force for a period of one-year
          (1) thereafter, unless earlier terminated as provided herein.  This
          Agreement will renew automatically for successive one-year periods
          until expiration of the commercial usefulness of the Search Results,
          until either party gives written notice to the other party of its
          intent not to renew no less than thirty (30) days prior to the end of
          the previous one-year period, or until terminated pursuant to Section
          8.2 or 8.3.

     8.2  Termination for Breach. If Affiliate breaches any covenant,
          ----------------------
          representation and/or warranty of this Agreement, or if Affiliate
          engages in any action that, in GoTo.com's sole discretion, reflects
          poorly on GoTo.com or otherwise disparages or devalues the GoTo.com
          Marks, or GoTo.com's reputation or goodwill, GoTo.com may terminate
          the Agreement immediately upon notice to Affiliate. If GoTo.com is
          unable to provide Search Results due to GoTo.com's substantial system
          failure or consistent service outages (except when such are caused by
          force majeure), then (a.) Affiliate may provide written notice of such
          failures or outages to GoTo.com or (b.) GoTo.com may terminate this
          Agreement. If Affiliate provides written notice to GoTo.com pursuant
          to this Section, then GoTo.com will have thirty (30) days to remedy
          the noted failures and outages. If GoTo.com does not remedy such
          failures and outages, Affiliate may terminate this Agreement.

     8.3  Termination Due to Insolvency. Either party may suspend performance
          -----------------------------
          and/or terminate this Agreement if the other party makes any
          assignment for the benefit of creditors or has any petition under
          bankruptcy law filed against it, which petition is not dismissed
          within 60 days of such filing, or has a trustee or receiver appointed
          for its business or assets or any party thereof.

     8.4  Effect of Termination.  Upon the termination of this Agreement for any
          ---------------------
          reason all license rights granted herein shall terminate immediately,
          and Affiliate shall immediately cease use of the GoTo.com Marks and
          the Search Results.
