                 MWP II           53.87997%
                 MWP III           2.84881%


          (b) At or prior to the Closing, the Operating Partnerships may obtain
          new loans or refinance existing debt of the Constituent Partnerships,
          which will be, or is secured by, certain Existing Properties and/or
          Contributed Properties. The amount of debt encumbering such Properties
          will affect the value of each of the Constituent Partnerships and the
          percentage of the total Contribution Amount allowable to each such
          Partnership.  Accordingly,  the parties agree that  proportional
          adjustments will be made in the percentages set forth in the table in
          Section 3(a) to reflect the difference  between the amount of
          indebtedness for borrowed funds which encumbers the Properties of a



          Constituent Partnership as of the Closing Date and the amount of such
          indebtedness as of the date of this Agreement. Furthermore, the
          parties acknowledge and agree that for income tax purposes, limited
          partners in the Operating Partnership, and the partners or other
          equity owners in such limited partners have assumed or guaranteed, or
          will wish to assume or guaranty certain indebtedness of their
          respective Constituent Partnerships. All parties acknowledge and agree
          that all limited partners or owners of interests therein shall be
          entitled to assume or guaranty  indebtedness  of the Operating
          Partnership as of the Closing Date in such proportions as they
          request.

          insured, solely in the name of the appropriate Contributing Entity as
          good and marketable by a national title insurance company (the "Title
          Insurance  Company") at regular rates pursuant to the standard
          stipulations and conditions of the 1970 Form B ALTA Owner's Title
          Insurance Policy as revised in 1984 and as the same may be modified by

          insurance shall be borne by the Operating Partnership.

          (b) The Contributing Entity shall have delivered to the Company prior

          financing statements filed with the Secretary of State and/or county
          clerk against its Contributed Properties, together with bankruptcy,
          tax lien and judgment searches and searches for pending litigation in
          all appropriate jurisdictions. It is a condition of Closing that such
          searches reveal that other than the Permitted Encumbrances there are
          no bankruptcies, actions, claims or liens affecting or encumbering or
          which might affect or encumber its Contributed Properties or any
          interest in its Contributed Properties which will continue after the
          Closing Date.

          (c) The Contributing Entity shall have delivered estoppel certificates
          acceptable to the Company obtained from lessors under any ground lease
          under which a Contributing Entity is a lessee.

          available, of all Leases and amendments thereto and guarantees
          thereof, all ground leases and all mortgages and related documents
          relating to its Contributed Properties directly to the Operating
          Partnership.

          (f) The Contributing Entity shall have executed and delivered a notice
          (suitable for reproduction) to tenants advising of the transfer of the
          Contributed Property to the Operating Partnership and advising the
          tenants to pay all future rentals to or upon the order of the
          Operating Partnership.

          (g) The Contributing Entity shall have delivered to the Operating
          Partnership, all Security Deposits, together with all interest earned
          thereon as of the Closing Date which the Contributing Entity is
          obligated, by law, contract or otherwise, to pay to tenants with
          respect to its Contributed Properties.

          (h) The Contributing Entity shall have delivered directly to the
          Company,  copies of building plans and  specifications for its
          Contributed Properties, if available.

          (i) The Contributing Entity shall have delivered directly to the
          Company, the following, to the extent in the possession of the
          Contributing  Entity:  copies of all certificates of occupancy,

          with proof of payment thereof (if any of the same have been paid), for
          current real estate and personal property taxes.

          (j) Each of the Contributing Entities shall have delivered to the
          Company, a Non-Foreign Transferor Certificate, certifying that such
          the Contributing Entity is not a "foreign person" within the meaning
          of Section 1445 of the Internal Revenue Code of 1986, as amended (the
          "Code").

          (k) The Contributing Entity shall have executed and delivered to the
          Company such other documents or instruments as in the reasonable
          opinion of counsel for the Company may be necessary to effectuate the
          transactions described in this Agreement, provided that such documents
          or instruments do not increase the liability of the Contributing
          Entities.

      6.10 MATERIAL ADVERSE CHANGES.

          (a) With respect to each of the Properties, since the date of the most

          not been any material adverse change in the business, results of
          operations,  properties,  assets or financial  condition of the
          Properties, respectively, or, to the best knowledge of the Constituent
          Partnership or the Contributing Entity, any event, condition or
          contingency that is likely to result in such a material adverse change
          and (b) neither the Constituent Partnership nor the Contributing

          (b) Neither the execution and delivery of this Agreement nor the
          consummation of any or all of the transactions contemplated hereunder
          will (i) entitle any current or former employee of the Company, any
          Constituent Partnership or any Contributing Entity to severance pay,

          (b) The books and records of the Contributing Entity, all of which
          have been or will be made available to the Company, are complete and
          correct, have been maintained in accordance with sound business
          practices and fairly reflect the assets, liabilities and operations of
          the Contributing Entity and the aforesaid financial statements are in
          conformity therewith.

     6.13 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since December 31, 1997, the
     business of the Contributing Entity has been conducted in the ordinary
     course and, except as shall be set forth on Schedule 6.13, the Contributing

     (a) incurred any indebtedness for money borrowed or any noncurrent
     indebtedness for the purchase price of any fixed or capital asset;

          (b) made (A) any change, except in the ordinary course of business, in
          its properties and assets or in its liabilities, (B) any commitment

          (c) made any change in its corporate charter or partnership agreement;

          (d) made any partnership or other distribution or payment, or set



          aside any amount for payment with respect to any partnership interest;

          other representative of the Contributing Entity;

          (f) amended any material contract, Lease or agreement;

          (g) entered into any agreement resulting in the imposition of any
          mortgage or pledge of, or the creation of any lien, charge or

          (h) voluntarily incurred any material obligation or liability,
          absolute or contingent, except in the ordinary course of business or
          pursuant to existing contracts and agreements described in this
          Agreement or in the Schedules delivered pursuant hereto.

     6.14 SUITABILITY. Each of the partners in the Constituent Partnerships and
     each of the Contributing Entities is an "accredited investor," or is
     represented by a "purchaser representative," as defined in Rule 501 of
     Regulation D promulgated under the Securities Act.

     6.15 INVESTMENT. Each of the partners in the Constituent Partnerships and
     each of the Contributing Entities is acquiring the L.P. Units for
     investment for such party's own account and not with a view to, or for
     resale, in connection with, any distribution of the L.P. Units, and such
     party has no present intention of selling or distributing any of such L.P.
     Units. Each of the partners in the Constituent Partnerships and each of the
     Contributing Entities understands that the L.P. Units have not been
     registered under the Securities Act by reason of a specific exemption from
     the registration provisions of the Securities Act which depends upon, among
     other things, the BONA FIDE nature of the party's investment intent as
     expressed herein.

     6.16 RULE 144. Each of the partners in the Constituent Partnerships and
     each of the Contributing Entities acknowledges that, because they have not
     been registered under the Securities Act, the L.P. Units constitute
     "restricted securities" as defined in Rule 144(a)(3) and must be held
     indefinitely unless subsequently registered under the Securities Act or an
     exemption from such registration is available. Each of the partners in the
     Constituent Partnerships and each of the Contributing Entities is aware of
     the provisions of Rule 144 promulgated under the Securities Act which
     permit limited resale of securities purchased in a private placement
     subject to the satisfaction of certain conditions, including, among other
     things, the existence of a public market for the securities, the
     availability of certain current public information about the issuer, the
     resale occurring not less than one year after a party has purchased and
     paid for the security to be sold, the sale being through a "broker's
     transaction" or in transactions directly with a "market maker" (as provided
     by Rule 144(f)) and the number of securities being sold during any
     three-month period not exceeding  specified  limitations (unless the
     securities satisfy the requirements of Rule 144(k)).

7. REPRESENTATIONS AND WARRANTIES WITH RESPECT TO THE PROPERTIES.

Each of the Contributing Entities represents and warrants to the Company and the
Operating Partnership, severally and for itself with respect only to the



particular Contributed Property or Contributed Properties being contributed by
such Contributing Entity, and each of the Constituent Partnerships (other than
MWP III) represents and warrants to the Company, severally for itself with

     7.1 TITLE TO PREMISES.

          (a) The Owner has not done or suffered or permitted to be done or
          committed any act or matter which would render legal and equitable

          insured as such by the Title Insurance Company, as specified in
          Section 5.4(a), subject only to the Permitted Encumbrances and the
          Leases.

          (b) There has been no violation by the Owner or its Properties of any
          provision, condition or agreement contained in any restrictive
          covenant, cross-easement agreement or similar instrument or agreement
          affecting its Properties or any portion thereof, which would have a
          material adverse effect on its Properties.

          (c) The Personal Property located on its Properties, other than that
          owned by tenants, utility companies or contractors is owned or leased
          by the Owner, includes all the types and approximate quantities of
          personal property heretofore owned or leased by the Owner and used in
          the ownership, operation and maintenance of the improvements located
          on its Properties and, if owned or leased by the Owner, as of the
          Closing Date, is owned or leased by the Owner free and clear of any
          liens or security interests of any kind, except for Permitted
          Encumbrances.

          (d) Its Properties are an independent unit which does not now rely on
          any  facilities (other than facilities covered by Permitted
          Encumbrances including, without limitation, any reciprocal easement
          agreements, or facilities of municipalities or public utility and
          water companies and other than parking areas which its Properties make
          legal use of under any reciprocal easement agreements) located on any
          property not included in its Properties to fulfill any requirement of
          any Governmental Body or for the furnishing to its Properties of any
          essential building systems or utilities.

          (e) Except as may be contained in the Leases, there are no purchase
          contracts, options, or any other agreements of any kind, written or
          oral, recorded or unrecorded, whereby any person or entity other than
          the Owner has or will have any basis to assert any right, title or
          interest in, or right to possession, use, enjoyment or proceeds of all
          or a portion of its Properties.

     7.2 LEASES.

          (a) Except for the Leases of its Properties to be set forth on
          Schedule 7.2(a), the Owner has not entered into any other contracts
          for the sale or leasing of its Properties or any portion thereof.

          (b) As of the Closing Date, no persons or entities, other than the
          Owner and the tenants under the Leases and their permitted subtenants



          and licensees, shall have any right to the possession, use or
          occupancy of its Properties or any portion thereof for any reason
          whatsoever.

          (c) As of the Closing Date, Schedule 7.2(c) (the "Rent Roll") will be
          true and correct in all material respects as of the date noted thereon
          and discloses all Leases and the rents due for the dates shown thereon
          (collectively, "Rents"). The Leases include all tenancies, licenses
          and subleases and other rights of occupancy or use for all or any
          portion of its Properties pursuant to which the Owner is landlord or
          licensor, all as amended, renewed and extended to the date of the Rent
          Roll, whether oral or written.

          (d) As of the Closing Date, Schedule 7.2(d) will contain a list of all
          security deposits given by the lessees under the Leases (the "Security
          Deposits"). Each Security Deposit has been and is held by the Owner or
          its agents in compliance with the respective Lease and applicable law.
          There are no unfulfilled obligations as to Security Deposits to
          tenants under Leases the terms of which have expired or been
          terminated and there is no suit, action or other claim made, or, to
          the knowledge of the Owner, pending or threatened with respect to any
          such Security Deposit.

          (e) The following is true with respect to each Lease:

               (i) the Lease is valid and existing and in full force and effect
               in accordance with its terms. No Lease has been modified, in

               (ii) all obligations of the lessor thereunder which accrue prior

               (iii) except for delinquencies in payment of rent of less than
               thirty (30) days, to the knowledge of the Owner there has been no
               material default or event which, with the giving of notice or the
               lapse of time, or both, would constitute a default, on the part
               of the lessor thereunder and, the tenant has not asserted and, to
               the knowledge of the Owner, has no defense to or offset or claim
               against its rent or the performance of its other obligations
               under the Lease;

               (iv) no tenant has prepaid any rent for more than one month if
               the lease term has commenced and two months if the lease term has
               not yet commenced;

               (v) the Owner has received no written notice from any tenant or
               any guarantor of a Lease that such tenant or guarantor is or may
               become unable or unwilling to pay its rent or other sums due
               under its Lease, continue to operate for the balance of the term
               of the Lease,  operate in accordance  with the exclusives

               material obligations under the Lease;

               (vi) the Owner has not, and to the knowledge of the Owner, no
               other person has, released or discharged any guarantor,
               voluntarily or involuntarily or by operation of law, from any



               obligation with respect to the Lease that such guarantor has
               guaranteed;

               (vii) at the time of Closing, no rents will have been assigned,
               pledged or encumbered;

               (viii) except as shall be set forth on Schedule 7.2(a) as of the
               Closing Date, the Owner does not own, directly or indirectly, (A)
               five percent (5%) or more of the total combined voting power of
               all classes of stock entitled to vote, or ten percent (10%) or
               more of the total number of shares of all classes of stock, of
               any tenant of its Properties or (B) an interest of ten percent
               (10%) or more in the assets or net profits of any tenant of its
               Properties; and

               (ix) all tenant improvements required under the Leases have been
               installed and/or completed, all costs relating thereto have been
               paid, and there is no on-going work with respect to any tenant
               improvement.

     construction, operation or maintenance of its Properties by the Owner in
     accordance with all applicable laws or used by tenants of its Properties in

     to cause or knowingly permit its Properties and its prior uses to fail to
     comply with, at all times, any applicable Environmental Laws (as hereafter
     defined) or any other governmental law, regulation or requirement relating
     to environmental and occupational health and safety matters and Hazardous

     "Environmental Laws" shall mean all statutes specifically described in the
     foregoing sentence and all federal, state and local environmental health
     and safety statutes, ordinances, codes, rules, regulations, orders and
     decrees regulating, relating to or imposing liability or standards
     concerning or in connection with Hazardous Materials. The term
     "Environmental Claim" shall mean any administrative, regulatory or judicial

     7.4 ENGINEERING MATTERS.

          (a) To the knowledge of the Owner there are no material defects in or

          conditioning, plumbing, electrical, drainage, fire alarm,
          communications, sprinkler, security and exhaust systems are in
          operational and working order and such systems do not contain any
          material hidden defect.

          (b) The Owner has no knowledge that the flood hazard area designation
          for its Properties as shown on a survey of its Properties is
          incorrect.

          (c) All water, sewer, gas, electric, telephone, and other public
          utilities and all storm water drainage necessary for the operation of
          its Properties (i) either enter its Properties through open public
          streets adjoining its Properties, or, if they pass through adjoining

          which (A) threatens to impair continued furnishing of such services to



          its Properties at regular rates and fees, or (B) could result in the
          discontinuance of such services presently available or necessary.
          Water and sanitary sewer provided for its Properties are public.

          space for the initial occupancy of each tenant under a lease, has
          heretofore been completed and/or paid for in full.

          (b) Except as may be set forth on Schedule 7.5(b) as of the Closing
          Date, there is no income derived from the Owner's Properties other
          than rental income and interest income. The rental income derived from
          its Properties constitutes "rent from real property" as defined in
          Section 856(d)(1) of the Code. The interest income derived from the
          operation of its Properties constitutes "interest" as defined in
          Section 856(c)(2)(B) of the Code.

     7.6 INSURANCE.

          (a) As of the Closing Date, Schedule 7.6 shall set forth an accurate
          and complete list of the insurance policies relating to its Properties
          or any part thereof and naming the Owner as an insured; all such
          policies are in full force and effect and all premiums thereunder as
          of the Closing Date have been paid to the extent due; and no notice of
          cancellation has been received with respect thereto and, to the
          knowledge of the Owner, none is threatened. The Owner represents that
          it does not currently self-insure with respect to any portion of the
          insurance, other than earthquake insurance.

          (b) The Owner has not received any notice from any insurance company
          of any defect or inaccuracies in any of its Properties, or any parts
          thereof, which would adversely affect the insurability of any of its
          Properties, or would increase the cost of insurance beyond that which
          would ordinarily and customarily be charged for similar properties in
          the vicinity of such Properties. All of its Properties are fully
          insured in accordance with prudent and customary practice.

          (c) To the knowledge of the Owner, the Owner has complied with all
          work orders, requirements and demands of each and every insurance
          company insuring all or any part of its Properties.

     7.7 REAL ESTATE TAXES AND ASSESSMENTS.

          (a) The copies of the real property tax bills for its Properties for
          the current tax year which have been furnished by the Owner to the
          Operating Partnership are true and correct and complete copies of all
          of such tax bills. All real estate taxes due and payable as of the
          Closing Date have been paid in full and there are no pending or, to
          the knowledge of the Owner, threatened proceedings for the correction
          or reduction of the assessed valuation of its Properties for the
          current or prior tax years.



          (b) Each of its Properties alone constitutes one or more entire tax
          parcel(s) for real estate tax purposes, and are not taxed as part of a
          larger tax parcel.

          (c) The Owner has not received notice that, and to the knowledge of
          the Owner, there are no public improvements in the nature of off-site
          improvements, or otherwise, which have been ordered to be made and/or
          which have not heretofore been assessed and there are no special or
          general assessments (other than regular, annual real estate taxes)
          pending against or presently being considered in formal municipal or
          quasi-municipal proceedings which will affect its Properties.

     7.8 CONDEMNATION; COMPLIANCE WITH LAWS, ETC.

          (a) The Owner has not received any written notice with respect to its
          Properties from any public authority concerning any eminent domain or
          condemnation proceeding, or any uncorrected violation of any
          ordinance, public regulation, statute, permit, site plan approval,
          zoning or subdivision regulation or urban redevelopment plan
          applicable to its Properties.

          (b) To the knowledge of the Owner, its Properties, when built, did not
          violate any federal, state, county or municipal laws, ordinances,
          codes, regulations or requirements affecting all or any of its
          Properties including, without limitation, housing, building, safety,
          health, environmental, fire or zoning ordinances, codes and
          regulations of the respective jurisdictions within which its
          Properties are located (together, "Applicable Laws").

          (c) To the knowledge of the Owner, there are no material unperformed
          obligations relative to its Properties outstanding pursuant to any
          written agreements with any Governmental Body.

          Registration Statement or any other document filed or to be filed with

          circumstances in which they were made, not misleading.

     announcement concerning the S-4 Registration Statement or any of the

     8.6 INDEMNIFICATION AND INSURANCE.

          (a) In the event of any threatened or actual claim, action, suit,
          proceeding or investigation, whether civil, criminal or
          administrative, including, without limitation, any such claim, action,
          suit, proceeding or investigation in which any of the present officers
          or directors of the Company is, or is threatened to be, made a party
          by reason of the fact that he is or was a director, officer, employee
          or agent of the Company, or is or was serving at the request of the
          Company as a trustee, director, officer, employee or agent of another
          corporation, partnership, joint venture, trust or other enterprise,
          whether before or after the Closing, the Company shall use its best
          efforts to defend against such claim, action, fact, proceeding or
          investigation and to respond promptly thereto. It is understood and
          agreed that the Company shall indemnify and hold harmless, as and to
          the full extent permitted by applicable law, each such officer or
          director against any losses, claims, damages, liabilities, costs,
          expenses (including attorneys' fees), judgments, fines and amounts
          paid in settlement in connection with any such claim, action, suit,
          proceeding or investigation, and in the event of any such claim,
          action, suit, proceeding or investigation (whether arising before or
          after the Closing), (i) the Company shall retain counsel reasonably
          satisfactory to the officer or director and shall pay all fees and
          expenses of such counsel for the officer or director promptly as
          statements therefor are received and (ii) the Company will use its
          best efforts to assist in the vigorous defense of any such matter;
          provided that the Company shall not be liable for any settlement
          effected without its prior written consent; and provided further that
          the Company shall have no obligation hereunder to any officer or
          director when and if a court of competent jurisdiction shall
          ultimately determine, and such determination shall have become final
          and non-appealable, that indemnification of such officer or director
          in the manner contemplated hereby is prohibited by applicable law. Any
          officer or director wishing to claim indemnification under this
          Section 8.6(a), upon learning of any such claim, action, suit,
          proceeding or investigation, shall notify the Company thereof.

          of any of the Company's Subsidiaries as in effect as of the date
          hereof with respect to matters occurring prior to the Closing shall
          survive the Closing and shall not be amended in a manner which would

          of time.

          parties of: (i) the occurrence, or failure to occur, of any event that

          contained in this Agreement to be untrue or inaccurate in any material
          respect at any time from the date of this Agreement to the Closing
          Date (except for changes permitted or contemplated by this Agreement),
          (ii) any failure of such party to comply with or satisfy, in any

          may violate the rights of or confer remedies upon such third party,
          and (iv) any notice of, or other communication relating to, any
          violation of Applicable Laws, any litigation or any order or judgment
          entered or rendered therein.

     practicable, (a) use commercially reasonable efforts to obtain all Required
     Consents, and give all necessary notices to and make all necessary filings

               Closing Date.

               (ii) It shall operate and manage its Properties in the same

               Applicable Laws.

               (vi) It shall maintain the insurance policies on the Properties

     a manner which adversely affects the operation of such Property as a whole

          Berg agrees not to directly or indirectly acquire or develop, or
          acquire an equity ownership interest in any entity that has an
          ownership interest in any real property zoned for industrial or R&D
          use or which intends to acquire such interests (with the exception of
          investments in the securities of publicly-traded companies, which do
          not represent more than 10% of the outstanding voting securities
          thereof) in California, Oregon or Washington without first disclosing
          such investment opportunity to the Company and making such opportunity
          available to the Company subject to the approval of a committee of the
          Company's Board of Directors comprised solely of Independent
          Directors; PROVIDED, HOWEVER that the foregoing shall not apply to any
          acquisition, development or investment with respect to the Berg Land
          Holdings, or the Projects subject to the Pending Projects Acquisition
          Agreement, or the Excluded Properties (as defined in the S-4
          Registration Statement). The foregoing restriction shall remain in

          satisfied: (i) no nominee of the Berg Group is a member of the
          Company's board of directors and (ii) the Berg Group beneficially owns
          less than 25% of the outstanding Common Stock of the Company
          (including for these purposes all shares then issuable upon exercise
          of the Exchange Rights).

          (b) CERTAIN INTERESTED PARTY TRANSACTIONS. Effective as of the Closing



          Date, the Company and each party hereto who is a member of the Berg
          Group agrees that prior to undertaking any transaction or entering

          member beneficially owns at least 5% of the outstanding Equity
          interests shall be subject to prior review and approval by the
          Independent Directors Committee. If the proposed transaction or
          contract is not approved by the Independent Directors Committee, at
          least as to the Berg Group member(s)' involvement therein, such Berg
          Group member or members agree not to participate in the transaction or
          enter into such contract. The provisions of this Section 9.2(b) shall
          not apply to transactions or contracts of a minor nature determined in

          Directors Committee.

          (c) FREEDOM OF ACTION. Except as provided in Section 9.2(a) and (b),
          after the Closing Date neither Carl E. Berg nor any other member of
          the Berg Group shall have any obligation to the Company, the Operating
          Partnership, or the Company's shareholders or any other Limited
          Partners not to (i) engage in the same or similar activities or lines
          of business as the Company, (ii) invest or own any interest publicly
          or privately in, or develop a business relationship with, any
          corporation, partnership or other entity engaged in the same or
          similar activities or lines of business as, or otherwise in
          competition with, the Company, or (iii) do business with any client or
          customer of the Company. Neither Carl E. Berg nor any other member of
          the Berg Group shall have any obligation, or be liable, to the
          Company, or the Operating Partnership (A) for or arising out of the
          conduct described in (i), (ii), or (iii), above, (B) for exercising or
          failing to exercise his or the Berg Group's rights under this
          Agreement or any other Related Agreement to which he or they will be a
          party, (C) for exercising or failing to exercise his or the Berg
          Group's rights as a shareholder of the Company or as a Limited
          Partner, (D) for breach of any fiduciary or other duty to the Company,
          or the Operating Partnership by reason of the conduct described in
          (A), (B) or (C) above. Except as provided otherwise in Section 9.2(a)
          or (b), in the event that any member of the Berg Group, acquires
          knowledge of a potential transaction, agreement, arrangement or other
          matter which may be a corporate opportunity for both such Person and
          the Company, neither such Person nor its officers, directors,
          employees or former employees shall have any duty to communicate or
          offer such corporate opportunity to the Company, and neither such
          Person nor its officers, directors, employees or former employees
          shall be liable to the Company for breach of any fiduciary or other
          duty, as a shareholder or otherwise, by reason of the fact that such
          Person pursues or acquires such corporate opportunity for itself,
          directs such corporate opportunity to another Person or does not
          communicate such corporate opportunity or information regarding such
          corporate opportunity to the Company.

     9.3 RIGHT OF FIRST REFUSAL. The Company hereby grants to each Limited
     Partner the right of first refusal to purchase his, her or its pro rata
     share of any New Securities (as defined below) that the Company may, from
     time to time, propose to sell and issue. A Limited Partner's pro rata
     share, for purposes of this right of first refusal, is the ratio of the
     number of shares of Common Stock issuable upon exchange of the L.P. Units
     held by such Limited Partner immediately prior to the issuance of New



     Securities to the total number of shares of Common Stock outstanding
     immediately prior to the issuance of New Securities, assuming conversion or
     exchange of all outstanding securities convertible or exchangeable into
     Common Stock of the company. This right of first refusal shall be subject
     to the following provisions:

          (a) "NEW SECURITIES." "New Securities" shall mean any capital stock of
          the Company, whether or not now authorized, and rights, options or
          warrants to purchase such capital stock, and securities of any type
          whatsoever that are or may become convertible into capital stock;
          provided, however, that the term "New Securities" shall not include
          (i) securities issued pursuant to this Agreement and the Private
          Placement, (ii) securities issued upon exchange of L.P. Units, (iii)
          securities issued pursuant to the acquisition of another business
          entity or business segment of any such entity by the Company by
          merger, purchase of substantially all the assets of such entity or
          business segment or other reorganization whereby the Company or its
          shareholders will own more than fifty percent (50%) of the voting
          power of such business entity or business segment of any such entity,
          (iv) securities issued to officers, directors, employees or
          consultants of or to the Company pursuant to any stock option, stock
          purchase or stock bonus plan, agreement or arrangement approved by the
          board of directors of the Company, (v) securities issued to any
          financial institution in connection with a loan transaction approved
          by the board of directors of the Company, (vi) securities issued to
          vendors or customers or to other persons in similar commercial
          situations with the Company, provided such issuance is approved by the
          board of directors, (vii) securities issued in a public offering
          pursuant to a registration under the Securities Act with an aggregate
          offering price to the public of more than $7,500,000, (viii)
          securities issued in connection with any stock split, stock dividend
          or recapitalization of the Company, and (ix) any right, option or
          warrant to acquire any security convertible into the securities
          excluded from the definition of New Securities pursuant to subsections
          (i) through (viii) above.

          (b) NOTICE OF PROPOSED ISSUANCE. In the event the Company proposes to
          undertake an issuance of New Securities, it shall give each Limited
          Partner written notice of its intention, describing the type of New
          Securities, their price and the general terms upon which the Company
          proposes to issue such New Securities. Each Limited Partner shall have
          ten (10) days after any such notice is mailed or delivered to agree to
          purchase such Limited Partner's pro rata share of such New Securities
          for the price and upon the terms specified in the notice by giving
          written notice to the Company and stating therein the quantity of New
          Securities to be purchased.

          (c) SALE OF NEW SECURITIES. In the event the Limited Partners fail to
          exercise fully the right of first refusal within said ten (10) day
          period, the Company shall have sixty (60) days thereafter to sell or
          enter into an agreement (pursuant to which the sale of New Securities
          covered thereby shall be closed, if at all, within sixty (60) days
          from the date of such agreement) to sell the New Securities respecting
          which the Limited Partners' right of first refusal set forth in this
          Section 9.3 is not exercised, at a price and upon terms no more
          favorable to the purchasers thereof than are specified in the
          Company's notice to Limited Partners pursuant to Section 9.3(b). In



          the event the Company has not sold the New Securities within the
          foregoing period, the Company shall not thereafter issue or sell any
          New Securities without first again offering such securities to the
          Limited Partners in the manner provided in Section 9.3 (b) above.

          (d) ASSIGNMENT. The rights granted by the Company pursuant to this
          Section 9.3 may be assigned by any Limited Partner to a transferee or
          assignee of not less than 500,000 L.P. Units (as adjusted for stock
          splits, combinations and the like), provided that such assignment may
          otherwise be effected in accordance with applicable securities laws
          and that the Company is given written notice at the time of said
          assignment stating the name and address of said transferee or assignee
          and identifying the securities with respect to which such rights are
          being assigned.

          (e) TERMINATION OF RIGHT OF FIRST REFUSAL. The right of first refusal
          granted under this Section 9.3 shall terminate upon the earlier of (i)
          May 14, 2003 or (ii) written agreement of the Company and the holders
          of a majority of the L.P. Units then outstanding.

     9.4 REIT ELECTION. After the Closing, the Company agrees to take all action
     necessary to qualify as a REIT and to make an election to be taxed as a
     REIT in the tax year ending December 31, 1998.

     9.5 BERG GROUP BOARD REPRESENTATIVES; REQUIRED DIRECTORS CONSENT; SUPER
     MAJORITY APPROVAL. The Company agrees that the Berg Group will have the
     right to nominate two directors for election to the board of directors so
     long as the Berg Group members together with their Affiliates (other than
     the Company and the Operating Partnership) own at least 15% of the Equity
     Securities of the Company treating all L.P. Units owned by such members and
     their Affiliates as Common Stock for this purpose, and the right to
     nominate one director if such ownership interest is less than 15% but at
     least 10% of such Equity Securities. The Company agrees to take all steps
     necessary to cause the election of such Berg Group nominees to the board of
     directors.  The Company agrees that until the Protective Provisions
     Expiration Date it will not take or permit to be taken any of the following
     actions without the approval of the Required Directors (in addition to all
     other approvals required by the Company's articles of incorporation,
     bylaws, contracts or applicable law): (i) establishing a quorum for any
     meeting of the board of directors which is not attended by a Required
     Director; (ii) amending the Company's articles of incorporation or bylaws;
     (iii) merging the Company with or into any other Entity; or (iv) any sale
     of all or substantially all of the Company's assets. The Company agrees
     further, and the bylaws of Mission West-Maryland shall provide following
     the Reincorporation Merger that the approval of more than 75% of the entire
     board of directors will be required for (i) the Company's taking title to
     assets or conducting business other than through the Operating Partnership,
     (ii) the termination of the Company's status as a REIT; and (iii) incurring
     indebtedness in excess of 50% of the Company's Total Market Capitalization.

     9.6 REINCORPORATION MERGER. After the Closing, and subject to Shareholder
     Approval of the Reincorporation Merger, the Company shall take all actions
     and file all documents necessary and shall cause Mission West-Maryland to
     take all actions and file all documents necessary to effectuate the
     Reincorporation Merger. The Company agrees to cause the provisions of
     Sections 9.2 and 9.5 to be incorporated into either the Articles of
     Incorporation or the Bylaws of Mission West-Maryland.



     9.7 OPERATION OF THE OPERATING PARTNERSHIP.

          (a) CASH; DISTRIBUTIONS. The Constituent Partnerships acknowledge and
          agree that from and after the Closing Date, as provided in the
          Operating Partnership Agreement, the Available Cash will be commingled
          and used to pay the obligations of all Constituent Partnerships. In
          addition,  the Operating  Partnership  shall and will make any
          distributions of Available Cash to the Constituent Partnerships on a
          pro rata basis in proportion to the ratio of the number of L.P. Units
          then outstanding in each such limited partnership to the total member
          of L.P. Units then outstanding in the Operating Partnership, and shall
          pay distributions simultaneously to the General Partner of each
          Constituent Partnership in accordance with the General Partner's
          interest in each such limited partnership.  Notwithstanding the
          foregoing, separate books and records shall be maintained for each
          Constituent Partnership,  and all costs shall be accounted for
          separately and properly credited to the general ledger of each
          Constituent Partnership.

          (b) FUTURE OPERATIONS. The Company, as general partner of the
          Operating Partnership, shall make investment, financing and
          operational decisions as though the Operating Partnership was a
          consolidated entity; provided that accounts, books and records shall
          be properly maintained on a separate basis for each Constituent
          Partnership. The Operating Partnership may transact business and
          otherwise act for all of the Constituent Partnerships in the name
          "Mission West Properties, L.P." The Company, as general partner of the
          Operating Partnership, shall endeavor to structure all transactions in
          such manner as will maintain the current pro rata interests of each
          Constituent Partnership, and of the Limited Partners thereof, to the
          Operating Partnership, as a whole, based on the ratio which the
          outstanding L.P. Units of each such limited partnership bears to the
          total number of L.P. Units set forth on Schedule 6.

     9.8 REIT QUALIFICATION OF THE COMPANY. For the purposes of Section
     856(a)(6) and (h) of the Code, the Berg Group members agree that they shall
     not own (within the meaning of Section 544(a) of the Code), both
     individually and as a group, more than 20% of the total value of the
     Company's outstanding stock (as determined for purposes of Section
     542(a)(2) of the Code) (the "Berg Ownership Limit"); and (ii) for purposes
     of all other ownership attribution rules under the Code (in particular
     Section 318 of the Code), no single Berg Group member shall directly or
     indirectly own 50% or more of the value of the Company's outstanding stock.
     The Berg Group members further agree that at no time while the Company is a
     REIT shall they acquire or permit any person within their control to
     acquire shares of Common Stock or other Equity Securities of the Company if
     such acquisition would cause the Company to fail to satisfy the REIT
     requirement that five or fewer individuals cannot own more than 50% of the
     value of the Company's outstanding stock within the meaning of Sections
     544(a)(2) and Section 856(a)(6) and (h) of the Code. The Company
     acknowledges and agrees that the right of Limited Partners to exchange L.P.
     Units for Common Stock pursuant to the Exchange Rights Agreement does not
     constitute the ownership of stock by such Limited Partners under Section
     544(a) or 318 of the Code.

10.   SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION.



     10.1 SURVIVAL. All representations, warranties and agreements contained in
     this Agreement or in any certificate delivered pursuant to this Agreement
     shall survive the Closing for a period of one year.

     10.2 INDEMNIFICATION. Each party to this Agreement shall severally
     indemnify and hold harmless all other parties and their Affiliates, for any
     loss, liability, claim, damage, expense (including, but not limited to,
     costs of investigation and defense and reasonable attorneys' fees) or
     diminution of value (collectively, "Damages") arising from or in connection
     with (a) any inaccuracy in any of the representations and warranties of
     such party in this Agreement, (b) any failure by such party to perform or
     comply with any covenant, obligation or agreement in this Agreement, (c)
     any liabilities of such party not specifically assumed by the Operating
     Partnership or the Company hereunder, (d) any claim by any Person for
     brokerage or finder's fees or commissions or similar payments based upon
     any agreement or understanding alleged to have been made by any such Person
     with such party (or any Person acting on such party's behalf) in connection
     with any of the Proposed Transactions.

     10.3 PROCEDURE FOR INDEMNIFICATION. Promptly after receipt by an
     indemnified party ("Indemnified Party") under Section 10.2 of notice of the
     commencement of any action, such Indemnified Party shall, if a claim in
     respect thereof is to be made against an indemnifying party ("Indemnifying
     Party") under such section, give notice to the Indemnifying Party of the
     commencement thereof, but the failure so to notify the Indemnifying Party
     shall not relieve it of any liability that it may have to any Indemnified
     Party except to the extent the Indemnifying Party demonstrates that the
     defense of such action is prejudiced thereby. In case any such action shall
     be brought against an Indemnified Party and it shall give notice to the
     Indemnifying Party of the commencement thereof, the Indemnifying Party
     shall be entitled to participate therein and, to the extent that it shall
     wish, to assume the defense thereof with counsel reasonably satisfactory to
     such Indemnified Party and, after notice from the Indemnifying Party to
     such Indemnified Party of its election so to assume the defense thereof,
     the Indemnifying Party shall not be liable to such Indemnified Party under
     such section for any fees of other counsel or any other expenses, in each
     case subsequently incurred by such Indemnified Party in connection with the
     defense thereof, other than reasonable costs of investigation. If an
     Indemnifying Party assumes the defense of such an action, (a) no compromise
     or settlement thereof may be effected by the Indemnifying Party without the
     Indemnified Party's consent unless (i) there is no finding or admission of
     any violation of law or any violation of the rights of any Person and no
     effect on any other claims that may be made against the Indemnified Party
     and (ii) the sole relief provided is monetary damages that are paid in full
     by the Indemnifying Party and (b) the Indemnifying Party shall have no
     liability with respect to any compromise or settlement thereof effected
     without its consent (which consent will not be unreasonably withheld). If
     notice is given to an Indemnifying Party of the commencement of any action
     and it does not, within ten (10) days after the Indemnified Party's notice
     is given, give notice to the Indemnified Party of its election to assume
     the defense thereof, the Indemnifying Party shall be bound by any
     determination made in such action or any compromise or settlement thereof
     effected by the Indemnified Party. Notwithstanding the foregoing, if an
     Indemnified Party determines in good faith that there is a reasonable
     probability that an action may adversely affect it or its affiliates other
     than as a result of monetary damages, such Indemnified Party may, by notice



     to the Indemnifying Party, assume the exclusive right to defend, compromise
     or settle such action, but the Indemnifying Party shall not be bound by any
     determination of an action so defended or any compromise or settlement
     thereof effected without its consent (which consent shall not be
     unreasonably withheld). Notwithstanding the foregoing, any determination
     with respect to the Company's determination to make a claim for
     indemnification against the Contributing Entities shall be made solely by a
     majority of the Independent Directors.

11.   TERMINATION.

     11.1 TERMINATION.

          (a) This Agreement may be terminated by the Company or by Carl E. Berg
          before the Closing occurs, whether before or after the Shareholder
          Meeting, only as follows:

               (i) if the consummation of the Proposed Transactions by the
               Company would violate any non-appealable final order, decree or
               judgment of any Governmental Body having competent jurisdiction;

               (ii) if any material representation or warranty of the Operating
               Partnership or any of the Contributing Entities or the
               Constituent Partnerships made herein is untrue in any material
               respect (other than a change permitted or contemplated by this
               Agreement) and such breach is not cured within 60 days of receipt
               of a notice from the Company that such breach exists or has
               occurred;

               (iii) if the conditions to the Company's obligations to 
               consummate the Closing as set forth in Sections 5.3 and 5.4 
               cannot reasonably be satisfied on or before September 30, 1998;

               (iv) if the Company's shareholders do not approve the Private
               Placements and the Berg Acquisition at the Special Meeting.

          (b) This Agreement may be terminated by the Company alone if any
          consent of any Limited Partner other than a Limited Partner who is a
          member of the Berg Group shall not have been obtained on or before the
          Closing Date.

     11.2 EFFECT OF TERMINATION. In the event that this Agreement is terminated
     pursuant to Section 11.1, this Agreement shall terminate without any
     liability or further obligation of any party to another, except for
     Sections 8.6, 10.2, and 10.3 which shall survive termination. A termination
     under Section 11.1 shall not relieve a defaulting or breaching party (or
     any party who has liability under this Agreement in respect of the actions
     of a defaulting or breaching party) from any liability to the other party
     or parties hereto for or in respect of such default or breach.

12.   NOTICES.

     All notices, consents and other communications under this agreement shall
     be in writing and shall be deemed to have been duly given when (a)
     delivered by hand, (b) sent by facsimile transmission (with receipt
     confirmed), provided that a copy is mailed by registered mail, return
     receipt requested, or (c) when received by the addressee, if sent by



     Express Mail, Federal Express or other express delivery service (receipt
     requested), in each case to the appropriate addresses, and telecopier
     numbers set forth in Appendix I hereto (or to such other addresses, and fax
     numbers as a party may designate as to itself by notice to the other
     parties).

13.   GOVERNING LAW; JURISDICTION; ETC.

     13.1 GOVERNING LAW. This Agreement and (unless otherwise provided) all
     amendments hereof and waivers and consents hereunder shall be governed by
     the internal laws of the State of California, without regard to the
     conflicts of law principles thereof.

     13.2 JURISDICTION. Any action or proceeding seeking to enforce any
     provision of, or based on any right arising out of, this agreement may be
     brought against any of the parties in the courts of the State of
     California, or, if it has or can acquire jurisdiction, in the Northern
     District of California, and each of the parties hereby consents to the
     jurisdiction of such courts (and of the appropriate appellate courts) in
     any such action or proceeding and waives any objection to venue laid
     therein.

14.   MISCELLANEOUS.

     14.1 SPECIFIC PERFORMANCE. The parties acknowledge that the subject matter
     of this Agreement is unique and that no adequate remedy of law would be
     available for breach of this Agreement. Accordingly, each party agrees that
     the other parties will be entitled to an appropriate decree of specific
     performance or other equitable remedies to enforce this Agreement (without
     any bond or other security being required) and each party waives the
     defense in any action or proceeding brought to enforce this Agreement that
     there exists an adequate remedy at law.

     14.2 CAPTIONS. The captions or headings of the Sections of this Agreement
     are for convenience only, and shall not control or affect the meaning or
     construction of any of the terms or provisions of this Agreement.
     References in this Agreement to Sections are references to Sections of this
     Agreement, unless expressly stated to the contrary. References in this
     Agreement to Schedules are, unless expressly stated to the contrary,
     references to Schedules to this Agreement, each of which is part of this
     Agreement.

     14.3 NO WAIVER. The failure of a party to insist upon strict adherence to
     any term of this Agreement on any occasion shall not be considered a waiver
     or deprive that party of the right thereafter to insist upon strict
     adherence to that term or any other term of this Agreement. Any waiver must
     be in writing.

     14.4 ENTIRE AGREEMENT; AMENDMENT. This Agreement supersedes all prior
     agreements among the parties with respect to its subject matter, and is
     intended (with the documents referred to herein) as a complete and
     exclusive statement of the terms of the agreement among the parties with
     respect thereto and cannot be changed or terminated except by a written
     instrument executed by the party or parties against whom enforcement
     thereof is sought. This Agreement shall bind and inure to the benefit of
     the parties hereto and their respective heirs, executors,  personal
     representatives, successors and assigns.



     14.5 BINDING NATURE. This Agreement shall be binding on each party hereto
     at the time that such party executes this Agreement notwithstanding that
     other signatories hereto executed and delivered the Agreement at a later
     date or not at all.

     14.6 COUNTERPARTS. This Agreement may be executed in counterparts and
     delivered by electronic facsimile transmission, and each signed counterpart
     transmitted by electronic facsimile shall be considered an original, but
     all of which together shall constitute the same instrument.

                 [Remainder of page intentionally left blank]



                   SIGNATURE PAGES OF ACQUISITION AGREEMENT

IN WITNESS WHEREOF, the parties hereto have hereunto executed this Agreement 
as of the first date written above, and a party's signature hereon in any 
capacity shall constitute such party's execution of this Agreement in all 
capacities which the party holds for purposes of this Agreement.
