  The following is a biographical summary of the business experience of the Company’s executive officers and directors:
  Carl E. Berg.Mr. Berg has served as Chairman of the Board and Chief Executive Officer of the Company since 1997. Since 1979, Mr. Berg has been a general partner of Berg & Berg Developers and has been a director and officer of Berg & Berg Enterprises, Inc. since its inception.

Mr. Roher brings extensive knowledge of finance and investments in both public and private companies, as well as his knowledge of the real estate industry.
  Director Independence
  The Board has determined that for all of 2011 Messrs. Hasler, Helzel and Roher were “independent,” as defined under Marketplace Rule 5605(a)(2) of the NASDAQ Stock Market (the “NASDAQ”) and are independent as of the date of this proxy statement. No director qualifies as independent unless the Board determines that the director has no direct or indirect material relationship with the Company. On an annual basis, each director and executive officer is obligated to complete a Director and Officer Questionnaire which requires disclosure of any transactions with the Company in which the director or executive officer, or any member of his or her immediate family, have a direct or indirect material interest. The Company also independently reviews the relationship of the Company to any entity for whom one of its directors is an employee or a member of the board of directors. The Board has determined that all director nominees, other than Messrs. Berg and Marino, are independent in accordance with the United States Securities and Exchange Commission (the "SEC") rules and regulations and the NASDAQ Marketplace Rules. The Board has concluded that there are no business relationships that are material or that would interfere with the exercise of independent judgment by any of these directors in their service on the Board or its committees. The Audit Committee and the Compensation Committee are comprised solely of independent directors, and the nomination of directors for election at the Annual Meeting is approved by the Independent Directors Committee.
   Code of Business Conduct and Ethics
  The Company adopted a code of business conduct and ethics that applies to all of its directors, officers and employees. The code of ethics is available on the Company’s website at www.missionwest.com. If the Company makes any substantive amendments to the code of ethics or grants any waiver, including any implicit waiver, from a provision of the code to the Company’s Chief Executive Officer, President and Chief Operating Officer, Vice President of Finance and Controller, or persons performing similar functions, where such amendment or waiver is required to be disclosed under applicable SEC rules, the Company intends to disclose the nature of such amendment or waiver on its website.
  Board Leadership Structure and Role in Risk Oversight
  Mr. Carl E. Berg has served as Chairman of the Board and Chief Executive Officer since the Company’s formation in September 1997. The Board believes it is important to select its Chairman and the Company’s Chief Executive Officer in the manner it considers in the best interests of the Company at any given point in time. The members of the Board possess considerable business experience and in-depth knowledge of the issues the Company faces, and are therefore in the best position to evaluate the needs of the Company and how best to organize the Company’s leadership structure to meet those needs. The Board believes that the most effective leadership structure for the Company at this time is for Mr. Berg to serve as both the Company’s Chairman and Chief Executive Officer because it demonstrates that the Company is under strong, unified leadership, with a single person developing and implementing strategic initiatives. Mr. Berg’s long tenure with the Company provides a stable leadership that is beneficial to the Company and its stockholders. In particular, the Board recognizes that, given Mr. Berg’s familiarity with the Company’s properties and day-to-day operations and his long-standing experience with the Company, it is valuable to have him lead Board discussions. The Company does not have a lead independent director. Rather, the three independent directors as a group fulfill the role of reviewing all proposed transactions that involve potential conflicts of interest, nominating directors (except for nominations reserved for the Berg Group under our organizational documents), and proposing matters for consideration or reviewing other actions by management for which independent review is required or considered appropriate. This is accomplished in their capacities as members of the Independent Directors Committee, Audit Committee and Compensation Committee. The Board and management view this level of independent director involvement as adequate given the nature of the Company and its business. In particular, due to the limited size of the Company’s operations and headcount, the well-defined nature of its business and operating results, and the relative infrequency of transactions (other than leases in the ordinary course of business) undertaken by the Company each year, the Company has not required more formal and extensive interaction, and the Board has not considered it necessary to date.
  With respect to the Board’s role in the risk oversight of the Company, the Board has set forth which transactions may require the prior approval of the Board or a committee of the Board and which transactions may proceed with management authorization and without any such Board prior approval. These cover transactions such as financings, property acquisitions, property dispositions, other investments and general corporate policies. Also, related party transactions are reviewed by the Independent Directors Committee.

  Number, Term and Election of Directors
  The Company’s Bylaws currently provide for a board of directors consisting of five directors. Each director serves for a term of one year or until the next annual meeting at which directors are elected and the director’s successor is elected and qualified.
  Designation of Certain Directors
  Under the Company’s Articles of Amendment and Restatement, or its Charter, its Bylaws and contracts with the “Berg Group,” which consists of Carl E. Berg, Clyde J. Berg, the members of their respective immediate families, and affiliated entities owning limited partnership interests, or O.P. units, in any of the Company’s six operating partnerships, the Berg Group has special rights with respect to meetings of the Board. A quorum for any meeting requires the presence of Carl E. Berg, or in the event of his death, disability or other event which results in his ceasing to be director, the presence of someone who Mr. Berg has designated to replace him (“Berg Designee”). With written consent from Mr. Berg or the Berg Designee, meetings of the Board may be held without the presence of either of them. Mr. Berg is obligated to submit a written statement identifying the Berg Designee to the Company from time to time and may amend the statement at his sole discretion. In addition, a majority of the Board, which must include Mr. Berg or the Berg Designee, is required for approval of any amendment to the Charter or Bylaws and any merger, consolidation or sale of all or substantially all of the Company’s assets or those of the Operating Partnerships. These special provisions will remain in effect as long as the Berg Group collectively owns at least 15% of the Company’s voting stock computed on a diluted, or “fully diluted,” basis taking into account all voting stock issuable upon the exercise of all outstanding warrants, options, convertible securities and other rights to acquire voting stock of the Company, and all O.P. units exchangeable or redeemable for common stock or other voting stock of ours without regard to any percentage ownership limit set forth in the Charter or Bylaws, or by agreement.
  Section 16(a) Beneficial Ownership Reporting Compliance
  Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company’s directors, executive officers and persons who own more than 10% of a registered class of the Company’s equity securities to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and other equity securities of ours. Directors, executive officers and greater than 10% holders are required by SEC regulation to furnish the Company with copies of all Section 16(a) reports they file.
  To the Company’s knowledge, based solely on review of the copies of the above-mentioned reports furnished to the Company and written representations regarding all reportable transactions, during the fiscal year ended December 31, 2011, all Section 16(a) filing requirements applicable to its directors, officers and greater than ten percent holders were complied with on time.
  -4-
  
 Item 11.   Executive Compensation
  Compensation Committee Interlocks and Insider Participation
  The Compensation Committee of the Board was formed in December 1998 and currently is comprised of Messrs. Hasler, Helzel and Roher. None of these individuals were at any time during 2011, or at any other time, an officer or employee of the Company. No executive officer of the Company serves as a member of the compensation committee or board of directors of any other entity that has one or more executive officers serving as a member of the Board or Compensation Committee.
  Compensation of Directors
  The Company pays each director who is not an employee of the Company an annual cash retainer for serving as director. The annual cash retainer is equal to $25,000 plus $1,500 for attendance (in person or by telephone) at each meeting of the Board of Directors, and $500 for attendance at each separate committee meeting. Employees who are also directors do not receive compensation for their services as directors.
  Each non-employee member of the Board who became or becomes a member of the Board automatically receives a grant of an option to purchase 50,000 shares of common stock at an exercise price equal to 100% of the fair market value of the common stock at the date of grant of such option upon joining the Board. The options become exercisable cumulatively with respect to 1/48th of the underlying shares on the first day of each month following the date of grant.  Generally, the options must be exercised while the optionee remains a director. All of the current directors received such an initial option grant.
  Under the 2004 Plan, the Board may authorize annual option grants or awards to non-employee directors at the Board of Director’s discretion as long as the number of shares or equivalent number of underlying shares of common stock, in the case of certain awards, does not exceed 50,000 per year. Such option grants or awards become exercisable cumulatively with respect to 1/48th of the underlying shares on the first day of each month following the date of grant. Generally, stock options must be exercised while the optionee remains a director. In addition, the full Board, acting through a disinterested majority, may authorize additional shares to a director who performs significant additional tasks, such as chairing a Board committee, or otherwise provides extraordinary service to the Board. Under the 2004 Plan, in the event of certain acquisitions representing the transfer of more than 50% of the voting power of the Company’s stock, all options and awards to non-employee directors will fully vest upon the completion of the acquisition.
  Although the Company considers option grants under the 2004 Plan to be an adequate form of long-term compensation for directors, to provide regular periodic compensation to the Company’s independent directors, each of the Company’s three non-employee directors has received an award of 45,000 dividend equivalent rights (“DER”). Each DER represents the right to receive payment of the dividend declared with respect to one share of common stock at the time the Company pays the dividend and continues in effect as to each recipient as long as he continues to serve on the Board.
  The following table sets forth the compensation for each independent director for the year ended December 31, 2011.

 COMPENSATION DISCUSSION AND ANALYSIS
  The Company’s Compensation Discussion and Analysis explains the material elements of the Company’s compensation arrangements for its three executive officers, Carl E. Berg, Raymond V. Marino and Wayne N. Pham (the “Named Executive Officers”), for the fiscal year ended December 31, 2011.
  The Company’s current executive compensation programs are determined and approved by the Compensation Committee of the Board. The Compensation Committee does not retain or rely on data provided by any independent compensation consultants regarding executive compensation. None of the Named Executive Officers is a member of the Compensation Committee. Mr. Berg, the Company’s Chief Executive Officer, recommends to the Compensation Committee the base salary, annual bonus and long-term compensation levels for the other Named Executive Officers. None of the other Named Executive Officers had any role in determining the compensation of any Named Executive Officers in 2011. Although Mr. Berg is a Named Executive Officer, in light of the Berg Group’s substantial financial interest in the Company, Mr. Berg never has received, and the Compensation Committee does not expect to pay him, incentive compensation of any kind.
  Executive Compensation Program Overview and Objectives
  In connection with the Compensation Committee’s responsibility of determining the compensation for the Named Executive Officers, the Compensation Committee seeks to:
  ·
attract, reward and retain highly qualified and motivated executives; and
 ·
ensure executive compensation is aligned with the Company’s corporate strategies, business objectives and the long-term interests of the Company’s stockholders;
  Executive Compensation Program Elements
  The material elements of the Company’s current executive compensation program for the Named Executive Officers, other than Mr. Berg, include the following:
  ·
an annual cash base salary,
 ·
an annual cash incentive bonus opportunity (at the discretion of the Compensation Committee),
 ·
long-term equity incentive awards,
 ·
DERs, and
 ·
401(k) retirement benefits.
  The Company believes that each executive compensation element helps it to achieve one or more of the Company’s compensation objectives.
  Compensation decisions are approved by the Compensation Committee. The Company does not have a set date or period during the fiscal year as to when compensation decisions are made. The evaluations of the Named Executive Officers, not including Mr. Berg, are solely determined by the Compensation Committee at the recommendation of the Chief Executive Officer. Accordingly, the Compensation Committee makes all compensation decisions when necessary and appropriate during the year.
  Base Salary
  Each Named Executive Officer receives a base salary. In general, the amount of this salary is intended to provide the executive with a base level of annual income that is not contingent on the Company’s performance. However, Mr. Berg’s base salary was set in 1998 not long after the Berg Group acquired control of the Company and has not been modified since. Initial base salaries paid to the Company’s other executive officers are intended to recognize each individual’s scope of responsibilities, past accomplishments, fundamental skills and experience within the industry. The Compensation Committee may give different weight to each of these factors for each executive officer, as it deems appropriate. None of the Company’s Named Executive Officers have an employment agreement. The Company’s policy is to pay the Named Executive Officers’ base salaries in cash. The base salaries are reviewed annually by the Compensation Committee and may be adjusted from time to time, at its discretion, to recognize increases in responsibility, outstanding individual performance and promotions.
  Mr. Marino and Mr. Pham’s duties and responsibilities remained unchanged from the previous year. They performed those duties as expected by the Board. The Compensation Committee believes that Mr. Marino and Mr. Pham are fairly compensated based on their level of experience, duties and responsibilities and taking into account their total compensation, including dividend equivalent rights and stock option grants. In addition, based on the Compensation Committee’s examination of other publicly traded companies within the real estate investment trust industry similar to the Company, both Mr. Marino and Mr. Pham are reasonably compensated. Following the recommendation of the Company’s Chairman and the committee members’ knowledge of industry compensation standards and reasonable judgment, the Compensation Committee determined that the base salaries of the Named Executive Officers should remain unchanged for 2011. Among other things, the Compensation Committee took into account the Company’s operating results, the Named Executive Officers’ specific duties and performance during the year, and general economic conditions for the industry and broader economy.
   -6-
 Annual Incentive Bonus
  The Company does not have an incentive bonus program or other bonus plan. However, the Compensation Committee may decide to grant bonuses in its discretion for outstanding individual performance and contributions to the Company. No incentive bonus was awarded in 2011.
  Long-Term Equity Incentive Awards
  The objectives of the Company’s long-term equity incentive compensation program are to:
  ·
reward achievement over a multi-year period,
 ·
align the interests of executives with those of stockholders by focusing executives on the stockholder return performance of the Company, and
 ·
provide a retention mechanism through multi-year vesting.
  The 2004 Plan allows for long-term equity incentive awards to executives and key employees of, and consultants and other service providers to, the Company, its subsidiaries and advisors through grants of stock option rights and other equity awards, including restricted stock, stock grants, restricted stock units, performance units, other stock-based compensation, including O.P. units exchangeable for shares of common stock, and dividend equivalent rights. Generally, awards are granted in the form of options to purchase shares of common stock of the Company. The awards align the recipient’s interest with the interests of stockholders by providing him with an ownership interest in the Company and a stake in the Company’s success. The 2004 Plan is administered by the Compensation Committee, which has the discretion to determine those individuals or entities to whom awards will be granted, the number of shares subject to such rights and awards and other terms and conditions of the grants. Each stock option award has a vesting period that is tied to each employee’s continued service to the Company.
  Stock Option Grants
  The Compensation Committee determines and approves all stock option grants and other equity awards to executive officers and has authorized the Company’s Chief Executive Officer to determine stock option grants and other equity awards for all other employees, subject to the Compensation Committee’s approval of total share allocations from the 2004 Plan. The Company’s policy has been to grant options to purchase shares upon hiring an executive and periodically thereafter as part of the annual performance reviews, presented to the Compensation Committee by Mr. Berg.  No options to purchase common stock have ever been granted to Mr. Berg, or any member of the Berg Group, under any compensation arrangement. In determining the initial size of stock option grants, the Compensation Committee considers the executive position with and responsibilities to the Company, potential for increased responsibility and promotion over the option term. In making additional option grants pursuant to performance reviews, the Compensation Committee bases its decision upon a subjective evaluation of the executive officers’ performance in meeting the Company’s corporate objectives. Generally, each stock option grant allows the executive officer to purchase shares of the Company’s common stock at a price per share equal to the market value on the date of grant, but the Compensation Committee has the power to grant options at a lower price if considered appropriate under the circumstances.
  Each stock option grant generally becomes exercisable, or vests, in installments over time (typically monthly over four years), or contingent upon the executive’s continued employment with the Company. The stock option grants generally expire on the sixth anniversary of the grant date.
  The Company has established a policy and procedure for stock option grants that includes the following principles:
  ·
the Compensation Committee determines and approves all stock option awards;
 ·
the grant date of stock option awards is always the date of the approval of the grants;
 ·
management has no control over selecting the date;
 ·
the exercise price of the stock options is equal to fair market value, which under the 2004 Plan is the closing price of a share of common stock on the date of grant on the NASDAQ Stock Exchange;
 ·
the maximum number of shares subject to option grants to an individual during the calendar year cannot exceed 500,000 shares under the 2004 Plan; and
 ·
stock option awards are promptly reported on Form 4 with the Securities and Exchange Commission for all Named Executive Officers.
  The Company grants options infrequently at the Compensation Committee’s discretion. The Company does not have a policy providing for the coordination of option grants with the release of material non-public information.
  -7-
  
  Dividend Equivalent Rights
  In April 2005, the Compensation Committee approved awards of 80,000 DERs to Mr. Marino and 20,000 DERs to Mr. Pham under the 2004 Plan. Each such DER represents the current right to receive the dividend paid on one share of the Company’s common stock when paid by the Company, for as long as the recipient remains employed by the Company. The DERs were awarded to enable these executives to participate in distributions to stockholders without having to exercise their stock options, which may not have significant value in the short run.
  The dividend rate declared in 2011 was $0.52 per share of common stock. Consequently, in 2011, the Company paid $41,600 and $10,400 to Messrs. Marino and Pham, respectively, with respect to their DERs.
  401(k) Retirement Benefits
  The Company provides retirement benefits to all of its Named Executive Officers under the terms of its tax-qualified 401(k) defined contribution retirement plan. Each year the Company makes an automatic matching contribution on behalf of each participant equal to 15% of the participant’s compensation, regardless of whether the participant contributes to the plan. The Named Executive Officers participate in the plan on substantially the same terms as the Company’s other participating employees.
  For 2011, the Company made 401(k) plan contributions in the amounts of $22,500, $36,750 and $22,320 for Messrs. Berg, Marino and Pham, respectively.
  Tax Considerations
  The Compensation Committee endeavors to award compensation that will be deductible for income tax purposes. Section 162(m) of the Internal Revenue Code generally disallows a tax deduction to publicly-held companies for compensation paid to “covered” executive officers, to the extent that compensation paid to such an officer exceeds $1 million during the taxable year. None of the compensation paid to the Company’s covered executive officers for the year ended December 31, 2011, that would be taken into account in determining a Section 162(m) limitation exceeded the $1 million limit. The Company’s 2004 Plan and awards to executives under that plan have been structured so that any compensation deemed paid to an executive officer in connection with the exercise of options with an exercise price equal to the fair market value the shares on the grant date will qualify as performance-based compensation that will not be subject to the $1 million limitation. The Compensation Committee does not expect to take any action at this time to modify cash compensation payable to the executive officers that would result in the application of Section 162(m).

 Option Exercises in Last Fiscal Year
  There was no exercise of option awards by the Named Executive Officers during the year ended December 31, 2011.
  Potential Payments upon Termination or a Change in Control
  The Company does not have any employment agreements or any arrangements or commitments with regard to the payment of compensation upon termination of employment or a change in control of the Company with any of its Named Executive Officers.
  Contractual and Other Control Arrangements
  Special Board of Directors Voting Provisions. The Charter and Bylaws provide substantial control rights for the Berg Group. These rights include a requirement that Mr. Berg or his designee as director approve certain fundamental corporate actions, including amendments to the Charter and Bylaws and any merger, consolidation or sale of all or substantially all of the Company’s assets. In addition, the Bylaws provide that a quorum necessary to hold a valid meeting of the Board of Directors must include Mr. Berg or his designee. The rights described in the two preceding sentences apply only as long as the Berg Group members and their affiliates, other than the Company and the Operating Partnerships, beneficially own, in the aggregate, at least 15% of the outstanding shares of common stock on a fully diluted basis. In addition, directors representing more than 75% of the entire Board must approve other significant transactions, such as incurring debt above certain amounts, acquiring assets and conducting business other than through the Operating Partnerships.
  Board of Directors Representation. The Berg Group members have the right to designate two of the director nominees submitted by the Board to stockholders for election, as long as the Berg Group members and their affiliates, other than the Company and the Operating Partnerships, beneficially own, in the aggregate, at least 15% of the Company’s outstanding shares of common stock on a fully diluted basis. If the fully diluted ownership of the Berg Group members and their affiliates is less than 15% but is at least 10% of the common stock, the Berg Group members have the right to designate one of the director nominees submitted by the Board to stockholders for election. Its right to designate director nominees affords the Berg Group substantial control and influence over the management and direction of the Company.
  Substantial Ownership Interest. The Berg Group currently owns O.P. units representing approximately 72% of the equity interests in the operating partnerships. The O.P. units may be converted into shares of common stock, subject to limitations set forth in the Charter (including an overall 20% ownership limitation for the Berg Group), and other agreements with the Berg Group. Upon conversion these shares would represent voting control of the Company. The Berg Group’s ability to exchange its O.P. units for common stock permits it to exert substantial influence over the management and direction of the Company.
  Limited Partner Approval Rights. Mr. Berg and other limited partners of the Operating Partnerships, including other members of the Berg Group, may restrict the Company’s operations and activities through rights provided under the terms of the Amended and Restated Agreement of Limited Partnership which governs each of the Operating Partnerships and the Company’s legal relationship to each Operating Partnership as its general partner. Matters requiring approval of the holders of a majority of the O.P. units, which necessarily would include the Berg Group, include (i) the amendment, modification or termination of any of the Operating Partnership Agreements; (ii) the transfer of any general partnership interest in the Operating Partnerships, including, with certain exceptions, transfers attendant to any merger, consolidation or liquidation of the Company; (iii) the admission of any additional or substitute general partners in the Operating Partnerships; (iv) any other change of control of the Operating Partnerships; (v) a general assignment for the benefit of creditors or the appointment of a custodian, receiver or trustee of any of the assets of the Operating Partnerships; and (vi) the institution of any bankruptcy proceeding for any Operating Partnership.
  In addition, as long as the Berg Group members and their affiliates, beneficially own, in the aggregate, at least 15% of the outstanding shares of common stock on a fully diluted basis, the consent of the limited partners holding the right to vote a majority of the total number of O.P. units outstanding is also required with respect to (i) the sale or other transfer of all or substantially all of the assets of the Operating Partnerships and certain mergers and business combinations resulting in the complete disposition of all O.P. units; (ii) the issuance of limited partnership interests senior to the O.P. units as to distributions, assets and voting; and (iii) the liquidation of the Operating Partnerships.

  Item 13.   Certain Relationships and Related Transactions, and Director Independence
  Property Acquisitions and Financial Transactions between the Company and the Berg Group
  In the past, including fiscal year 2011, the Company has entered into agreements and engaged in transactions with Carl E. Berg, the Company’s Chief Executive Officer, Chairman and Director, and with other members of the Berg Group. The Company expects to enter into additional agreements and transactions with the Berg Group and Mr. Berg in the future. All such transactions and agreements must be approved for the Company by the Independent Directors Committee, as described above under “Director Independence.” The Independent Directors Committee is responsible for reviewing, evaluating and authorizing action with respect to any transaction between the Company and any member of the Berg Group.
  Formation of the Company. Through a series of transactions in 1997 and 1998, the Company became the vehicle for substantially all of the Silicon Valley R&D property activities of the Berg Group, which includes Mr. Berg, his brother Clyde J. Berg, members of their families and a number of entities in which they have controlling or substantial ownership interests. The Company owns these former Berg Group properties, as well as the rest of its properties, through the Operating Partnerships, of which the Company is the sole general partner. Through various property acquisition agreements with the Berg Group, the Company has the right to purchase, on pre-negotiated terms, R&D and other types of office and light industrial properties that the Berg Group develops in the future in the states of California, Oregon and Washington the details of which are set forth above. Since September 1998, the Company has acquired a total of approximately 3,386,000 million rentable square feet of R&D buildings under the Berg Land Holdings Option Agreement and the Pending Projects Acquisition Agreement, both of which have expired. The total cost of these properties was approximately $510 million. The Company issued a total of 28,510,261 O.P. units and assumed debt totaling approximately $232 million to acquire them. The last acquisition transaction with the Berg Group occurred in January 2008.
  The following transactions with the Berg Group occurred or effected the Company’s operations or financial condition since January 1, 2011:
  Property Acquisitions from the Berg Group.On February 1, 2012, the Company acquired three vacant R&D buildings located at 5901, 5921 and 5961 Optical Court in San Jose, California, from the Berg Group consisting of approximately 202,500 rentable square feet for a total purchase price of $18 million. The Company also acquired approximately ten acres of raw land at Hellyer Avenue and Embedded Way for approximately $5.3 million and nine acres of raw land at Hellyer Avenue and Piercy Road for approximately $4.9 million from the Berg Group. The combined purchase price for the three R&D buildings and raw land totaled approximately $28.2 million. The Company acquired these properties by offsetting the purchase price with approximately $9.2 million, the amount the Berg Group owed to the Company from the outcome of the Hellyer Avenue Limited Partnership litigation and approximately $7.5 million, the amount the Berg Group was obligated to pay toward the construction of an R&D building in connection with the Company’s 2001 acquisition of 245 Caspian Drive in Sunnyvale, California. The Company issued an unsecured short-term note payable for the remaining amount of approximately $11.5 million with an interest rate of LIBOR plus 1.75%, which is due July 15, 2012. As of March 31, 2012, the note payable and accrued interest had been fully repaid. The transaction was approved by the Independent Directors Committee of the Company’s Board of Directors.
  In December 2011, upon approval of the Independent Directors Committee of the board of directors, the Company effected a division of two of the operating partnerships, to create new holding vehicles for certain of the properties of each of such operating partnerships. In the first operating partnership division transaction, Mission West Properties, L.P. I (“MWP I”) formed a new Delaware limited partnership, Mission West Properties, L.P. IV (“MWP IV”), to which it contributed two buildings leased to Apple, Inc., a 211,000 square foot building located at 10050 N. De Anza Boulevard, Cupertino, CA  and a 105,000 square foot building located at 20400 Mariani Avenue, Cupertino, CA.  The terms of the MWP IV limited partnership agreement were made substantially identical to the terms of the limited partnership agreement of MWP I, and the relative interests of the Company as general partner and Carl Berg, Clyde Berg and Kara Berg as the limited partners in both partnerships remained the same. The total number of ownership units of operating partnership interests in the two limited partnerships after the division transaction was the same as the total number of outstanding O.P. units of MWP I prior to the division. To effectuate that, the number of O.P. units of MWP I equal to the number of new O.P. units issued by MWP IV were canceled, and such number of MWP IV O.P. units were issued in substitution for the former O.P. units in a transaction in which no consideration was paid by the distributee partners. In the second operating partnership division transaction, Mission West Properties, L.P. II (“MWP II”) created a new Delaware limited partnership, Mission West Properties, L.P. V (“MWP V”), to which it contributed a property consisting of 148,600 square feet of improvements located in three buildings at the corner of Montague and Trade Zone, California and unimproved Parcels 4, 5, 9, 10, 11, 12, and 13 of McCandless Technology Park, Milpitas, California, and distributed new O.P. units of MWP V to the Company and Carl Berg and Clyde Berg as the limited partners of MWP II in the same relative percentages as their ownership interests in MWP II. The total number of O.P. units of these two operating partnerships outstanding after the division transaction was the same as the total number of O.P. units of MWP II outstanding prior to the division. To effectuate that, the same number of MWP II O.P. units as the new O.P. units issued by MWP V were canceled, and such number of MWP V O.P. units were issued in substitution for the former O.P. units in a transaction in which no consideration was paid by the distributee partners. The terms of the MWP V limited partnership agreement are substantially identical to the terms of the limited partnership agreement of MWP II. The Company is the sole general partner of both of the new operating partnerships. The capitalization, properties, liabilities and respective interests of the Company and the operating partnerships as a whole have remained
 
 
 -14-
 
 the same following the operating partnership division transactions as they were prior to them, except that some properties formerly held in the name of MWP I now are held in the name of MWP IV, some properties formerly held in the name of MWP II now are held in the name of MWP V, and neither of the two new partnerships have any mortgage debt. The operating partnerships Mission West Properties, L.P. and Mission West Properties, L.P. III were unaffected by the transactions. There was no issuance of common shares associated with these transactions, and the total number of O.P. units outstanding was the same immediately before and after the transactions.
  Transfer of Interest to Berg Group in Consolidated Joint Venture. In July 2000, the Hellyer Avenue Limited Partnership (“Hellyer LP”) was formally organized as a California limited partnership between Mission West Properties, L.P. (“MWP”), of which the Company is the managing general partner, and Republic Properties Corporation (“RPC”), an unaffiliated third party, as a general partner and limited partner. MWP was designated as the managing general partner of Hellyer LP. For a 50% ownership interest in Hellyer LP, RPC agreed to cause Stellex Microwave Systems, Inc. (“Stellex”) to provide a 15-year lease on an approximate 160,000 square foot R&D building to be constructed by Berg & Berg Enterprises, Inc. (“BBE”) on land owned by another Berg Group member.
  As part of the transaction, MWP acquired the underlying land pursuant to the Berg Land Holdings Option Agreement for a price of $5.7 million by issuing 659,223 O.P. units to the Berg Group entity that owned the property. Further, under the terms of the Hellyer LP partnership agreement MWP then contributed the land to the partnership at an agreed value of $9.6 million which amount was to be amortized and paid to MWP in the form of income and cash flow preferences. The transaction was reviewed and approved by the Independent Directors Committee.
  In connection with the transaction, BBE built and paid for all improvements on the land. The total cost of the R&D building, exclusive of specified tenant improvements obligations, was approximately $11.4 million. Hellyer LP issued a note for the amount of those construction costs to BBE, which note was secured by the buildings.
  Because RPC’s interest in Hellyer LP was attributable solely to its commitment to obtain Stellex as a tenant for the property, the partnership agreement provided that if a payment default occurred within the first five years of the Stellex lease, RPC would lose 100% of its interest in the partnership, and if a payment default occurred during the second five year period under the lease, RPC would lose 50% of its interest in Hellyer LP.
  Pursuant to RPC’s commitment to Hellyer LP, Stellex executed a lease agreement obligating Stellex, among other things, to pay monthly rent starting at $1.60 per square foot on a triple net basis for 15 years and to reimburse BBE for the tenant improvement obligations, which ultimately totaled approximately $10.5 million. Under the lease terms, Stellex was obligated to reimburse BBE in full for the tenant improvement costs no later than August 25, 2000. Several days before the due date, representatives of Stellex met with representatives of the Company and informed them that Stellex could not pay the balance due BBE. Stellex requested the Company immediately to draw down the letter of credit as a result of a default on the tenant improvement payment required under the lease.
  On September 1, 2000, MWP, as the general partner of Hellyer LP, ceased all allocations of income and cash flow to RPC and exercised the right under the partnership agreement to cancel RPC’s entire interest in the partnership. Following discussions with and approval by the Independent Directors Committee, the Company authorized the transfer of RPC’s interest in Hellyer LP to BBE.  Under the Berg Land Holdings Option Agreement and the Acquisition Agreement dated as of May 14, 1998, the Independent Directors Committee had the right, but not the obligation, to reacquire the property interest and the related distributions related to the property interest at any time. The transfer was effective as of September 1, 2000.
  Stellex filed for bankruptcy protection on September 12, 2000. On November 20, 2000, RPC filed suit in the Circuit Court of Maryland for Baltimore City to recover past distributions and its interest in the Hellyer LP., and the Company counter-sued on behalf of MWP and itself in the Superior Court of California for the County of Santa Clara (the “California Action”) in February 2001. In January 2002, Stellex was acquired through its bankruptcy proceeding by a division of Tyco Corporation. In connection with the acquisition of Stellex, the purchaser assumed the lease with Hellyer LP, agreed to comply with all terms of the lease and reimbursed BBE for the tenant improvements, as required under the lease agreement and the Bankruptcy Court order.
  Since the inception of Hellyer LP, the Company has accounted for the properties owned by the partnership on a consolidated basis, with reductions for the noncontrolling interest held by the noncontrolling partner (first RPC and then BBE). In each period, the Company has accrued amounts payable by Hellyer LP to the noncontrolling interest partner, including BBE, prior to payment. Through December 31, 2011, accumulated cash flow distributions from Hellyer LP totaling approximately $7.9 million were accrued, of which $7.9 million was distributed to BBE, which has been classified on the Company’s consolidated balance sheets as an account receivable from BBE with an offsetting account payable to RPC. The Company did not object to that proposed classification.

  Pursuant to the final nonappealable judgment of the superior court in the California Action in 2011, RPC was reinstated as a partner in the Hellyer LP as of September 1, 2000, with the right to the return of all distributions paid to BBE on account of that interest since that date. Because RPC’s interest in the Hellyer LP had been transferred to BBE and past distributions from profits had been paid to BBE, the Company accrued approximately an interest receivable due from BBE, a total of approximately $9.2 million, consisting of the aggregate distributions and accrued interest, became payable  by BBE to the Company. In February 2012, upon approval by the Independent Directors Committee, the entire amount was applied as a partial offset by the Company of the purchase price for properties acquired from the Berg Group. See above under Property Acquisitions from the Berg Group for details of this application.
  Berg Obligation to Complete Future Improvements and Building in Connection with Certain Acquisitions from the Berg Group under the Berg Land Holdings Option Agreement. Since 2001, the Berg Group has had an approximately $7.5 million obligation to the Company to complete an approximately 75,000 to 90,000 rentable square foot building in connection with the Company’s 2001 acquisition of 245 Caspian in Sunnyvale, California, which consisted of approximately three acres of unimproved land zoned for commercial development. In February 2012, upon approval by the Independent Directors Committee, the Company applied the amount of that obligation towards the purchase price for properties acquired from the Berg Group. See above under Property Acquisitions from the Berg Group for details of this application.
  Leasing and Overhead Reimbursements Provided by Berg Controlled Entity. The Company currently leases office space owned by Berg & Berg Enterprises, Inc., an affiliate of Carl E. Berg and Clyde J. Berg.  Rental amounts and overhead reimbursements paid to Berg & Berg Enterprises, Inc. were approximately $0.1 million for the year ended December 31, 2011.
  Related Party Debt.As of March 31, 2012, debt in the amount of approximately $7.0 million was due the Berg Group under a mortgage note established May 15, 2000 in connection with the acquisition of a 50% interest in Hellyer Avenue Limited Partnership, the obligor under the mortgage note. The mortgage note bears interest at 7.65%, and is due in ten years with principal payments amortized over 20 years. In the fourth quarter of 2008, the Company and the Berg Group agreed to extend the loan maturity date to June 2013. Interest expense incurred in connection with the Berg Group mortgage note was approximately $0.1 million for the three months ended March 31, 2012.
  During the first three months of 2012, the Company issued two short-term notes payable to the Berg Group in connection with property acquisitions and quarterly dividend distributions. The interest rate on the two notes was LIBOR plus 1.75%. The aggregate loan amount totaled approximately $13.4 million. The Company repaid approximately $13.4 million to the Berg Group, which includes accrued interest.
  If the Company is unable to repay its debt to the Berg Group when due, the Berg Group could take action to enforce the Company’s payment obligations. Potential actions by the Berg Group to enforce these obligations could result in the foreclosure in one or more of the Company’s properties and a reduction in the amount of cash distributions to its stockholders. In turn, if the Company fails to meet the minimum distributions test because of a loan default or another reason, it could lose its REIT classification for federal income tax purposes.
  Berg Controlled Entities have Financial Interests in Certain Tenants that Lease Space from the Company. During the three months ended March 31, 2012, Carl E. Berg or entities controlled by Mr. Berg held financial interests in several companies that lease space from the operating partnerships, which include companies where Mr. Berg has a greater than 10% ownership interest. These related tenants contributed approximately $0.4 million in rental income for the three months ended March 31, 2012.
  Leasing and Overhead Reimbursements Provided by Berg Controlled Entity. The Company currently leases office space owned by Berg & Berg Enterprises, Inc., an affiliate of Carl E. Berg and Clyde J. Berg.  Rental amounts and overhead reimbursements paid to Berg & Berg Enterprises, Inc. were approximately $0.03 million for the three months ended March 31, 2012.
