The audit committee met three times during 1999.

      Directors who are also officers do not receive any separate compensation for serving as directors.

PROPOSAL 2

AMENDMENT TO CERTIFICATE OF

INCORPORATION TO INCREASE AUTHORIZED
COMMON STOCK AND PREFERRED STOCK

In General

      The board of directors has unanimously approved and determined to submit for shareholder approval a proposal to amend Article IV of our Amended and Restated Certificate of Incorporation to increase from 17 million to 95 million the number of shares of common stock that Mobile Mini is authorized to issue. The proposed amendment does not change the number of shares of preferred stock that we are authorized to issue, and there would continue to be 5 million shares of preferred stock authorized for issuance.

3


      If the shareholders approve this proposal, Article IV of Mobile Mini’s Amended and Restated Certificate of Incorporation will be will be deleted in its entirety and the following inserted therefor:

We expect to vote on these items at the meeting.

Purpose for Amendment

      The proposed increase in our authorized common stock will provide us with a sufficient number of shares of authorized and unissued common stock that can be issued, as the need may arise, in connection with future equity offerings, future acquisitions in which we pay all or a portion of the purchase price in shares of our common stock, future management incentive and employee benefit plans and other purposes. On April 26, 2000, the record date for this annual meeting, we had           shares of common stock outstanding, and an additional [          ] shares were reserved for issuance under our stock option plans and outstanding warrants, leaving a maximum of           shares of common stock available for issuance in the future. We do not presently have any commitments to issue a material number of new shares of common stock in the future. However, the availability of additional shares of common stock for issue in the future will give Mobile Mini greater flexibility in its financing and carrying out of our previously announced growth and expansion program, as well as for other purposes as they arise. The board of directors decided that the 5 million shares of preferred stock which we are presently authorized to issue is sufficient for foreseeable corporate needs. At present, we have no shares of preferred stock outstanding and all 5 million authorized shares of preferred stock are available for issuance with such terms, preferences, rights and limitations as the board may determine.

The Board of Directors Recommends a Vote “FOR” Proposal 2.

PROPOSAL 3

AMENDMENT TO CERTIFICATE OF

INCORPORATION REGARDING PROCEDURES
FOR NOMINATIONS OF PERSONS FOR ELECTION
TO THE BOARD OF DIRECTORS

In General

      The board of directors has unanimously approved and determined to submit for shareholder approval a proposal to amend our Amended and Restated Certificate of Incorporation to delete Article XV. Article XV presently sets forth a procedure which shareholders must follow if they desire to nominate a person for election as a director of Mobile Mini. Under Article XV, a shareholder must submit a written nomination to Mobile Mini not less than 60 days prior to the date of the annual meeting at which the shareholder desires that the nominee stand for election. Our Bylaws, as in effect, contain a provision under which shareholders may bring items of business, including nominations of directors, before an annual meeting of shareholders. Article XV of our certificate of incorporation and the Bylaw provision are not consistent with one another, and the board of directors has determined to resolve the inconsistency by deleting Article XV.

Purpose for Amendment

      Section 4.7 of our Bylaws provides that for business to be properly brought before an annual meeting by a shareholder, the shareholder must have given Mobile Mini timely notice of the business. To be timely, that notice must by received by Mobile Mini between 90 and 120 days before the meeting. Section 4.7 of our Bylaws serves two principal purposes: (1) it ensures that notice of any item of business that a shareholder proposes be brought before an annual meeting is received in time for our board to consider whether the item of business is appropriate to be put before a meeting and it provides adequate time to include an appropriate item of business in the proxy statement that the board of directors issues in connection with each annual meeting;

4


and (2) it permits the holders of proxies solicited by our board of directors to exercise discretionary voting authority on business brought before an annual meeting. The power of a proxy to exercise discretionary voting authority is subject to Rule 14a-4(c) promulgated by the Securities and Exchange Commission. Rule 14a-4(c) permits the exercise of discretionary voting authority at an annual meeting if we did not receive timely notice of the item of business. Section XV of our certificate of incorporation permits such notice to be delivered not less than 60 days prior to the annual meeting, while Section 4.7 require that such notice be delivered at least 90 days prior to an annual meeting. Unlike Section 4.7, however, Article XV applies only to the nomination of persons to serve as directors. The board determined to delete Article XV and thereby resolve the inconsistency between that Article’s timing requirements and those of Section 4.7 of the Bylaws.

The Board of Directors Recommends a Vote “FOR” Proposal 3.

PROPOSAL 4

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

      The board of directors has appointed Arthur Andersen LLP, independent public accountants, to audit the consolidated financial statements of Mobile Mini for the fiscal year ending December 31, 2000. In the event of a negative vote on such ratification, the board of directors will reconsider its selection. The board of directors anticipates that representatives of Arthur Andersen LLP will be present at the annual meeting, will have the opportunity to make a statement if they desire, and will be available to respond to appropriate questions.

The Board of Directors Recommends a Vote “FOR” Proposal 4.

OTHER MATTERS

      The board of directors knows of no other matters to be submitted to the annual meeting. If any other matters properly come before the meeting, it is the intention of the persons named in the enclosed proxy card to vote the shares they represent as the board may recommend.

COMPENSATION COMMITTEE INTERLOCKS

AND RELATED PARTY TRANSACTIONS

      Messrs. Berkner, Marusiak, and McConnell served as the members of the compensation committee of the board of directors during 1999. None of these directors was an executive officer or otherwise an employee of Mobile Mini before or during such service, and no executive officer of Mobile Mini served on any other company’s compensation committee.

      Mobile Mini leases a portion of the property comprising its Phoenix, Arizona location and the property comprising its Tucson, Arizona location from Richard E. Bunger’s five children (including Steven G. Bunger). Mr. Richard Bunger and Mr. Steven Bunger are executive officers and directors of Mobile Mini. Annual base lease payments under these lease total approximately $66,000, with annual adjustments based on the Consumer Price Index. Payments in 1999 for these leases were approximately $76,000. The term of each of these leases will expire on December 31, 2003. Additionally, Mobile Mini leases its Rialto, California facility from Mobile Mini Systems, Inc., a corporation wholly owned by Mr. Richard Bunger, for total annual base lease payments of $204,000, with annual adjustments based on the Consumer Price Index. Payments in 1999 for this lease was approximately $229,000. The Rialto lease is for a term of fifteen years, expiring on December 31, 2011. Management believes that the rental rates reflect the fair market rental value of these properties.

      Mobile Mini obtains services throughout the year from Skilquest, Inc., a company engaged in sales and management support programs. Skilquest, Inc. is owned by Carolyn Clawson, the daughter of Mr. Bunger and sister of Steven G. Bunger. Mobile Mini made aggregate payments of approximately $69,000 and $85,000 to

5


Skilquest, Inc. in 1998 and 1999, respectively, which Mobile Mini believes represented the fair market value for the services performed.

      During 1999, Mr. Bunger refurbished certain personally owned equipment at Mobile Mini’s facility and reimbursed Mobile Mini approximately $31,000 for labor and material used. Mr. Bunger had an additional $32,000 of work in process that Mobile Mini will be reimbursed for upon completion. Mobile Mini believes this amount represented the fair market value for the services performed.

      Mr. Bunger and Mobile Mini have entered into an agreement, dated December 30, 1999, whereby certain personally owned equipment of Mr. Bunger, valued at approximately $36,000, would be exchanged for certain other equipment Mobile Mini owns that is valued at the same approximate market value. Part of this exchange includes a 1996 Chevrolet Suburban owned by Mobile Mini that had been provided to Mr. Bunger. The value of the use of the vehicle is included in the compensation we paid Mr. Bunger, and is reflected at page 12 in the “Summary Compensation Table.”

      All ongoing and future transactions with affiliates will be on terms no less favorable than could be obtained from unaffiliated parties and will be approved by a majority of the independent and disinterested directors.

COMPENSATION COMMITTEE REPORT

ON EXECUTIVE COMPENSATION

      Mobile Mini’s executive compensation program is administered by the compensation committee of the board of directors, which is comprised only of independent directors as defined by the Securities and Exchange Commission and the Internal Revenue Service. As a part of its duties, the compensation committee reviews compensation levels and performance of Mobile Mini’s executive officers. The compensation committee also administers Mobile Mini’s short and long-term incentive programs.

      The following report of the compensation committee shall not be deemed to be incorporated by reference into any previous filing by Mobile Mini under either the Securities Act of 1933 or the Securities Exchange Act of 1934 that incorporates future Securities Act or Exchange Act filings in whole or in part by reference.

Compensation Philosophy

      Mobile Mini encourages each individual to enhance the value of Mobile Mini through their entrepreneurial efforts. As such, we position Mobile Mini’s base compensation levels for its executive officers consistent with the individual’s performance and skills and the competitive marketplace.

      Annual incentive payments are provided for achieving positive results that prepare Mobile Mini for strategic growth and continued financial strength. These results are usually expressed by reference to ranges of earnings targets set by the Compensation Committee following review of management’s projected financial plan for the year. Annual incentives are designed to provide total cash compensation at competitive levels relative to a peer group of companies in the durable goods leasing industry as warranted by performance.

      Long-term incentives in the form of stock options are provided to align the interests of management and the interests of the shareholders, as well as reward members of management for ongoing implementation of Mobile Mini’s strategic planning objectives.

      In total, the three elements of Mobile Mini’s executive officer compensation program are designed to provide a competitive compensation program taking into account Mobile Mini’s financial performance relative to its expectations and the peer companies’ performance.

Compensation of the Chairman

      Mr. Richard E. Bunger served as our Chairman of the Board throughout 1999. Mr. Bunger also serves as Director of Product Research and Market Development. During 1999, Mr. Bunger received base compensation of $245,000, an increase from the $183,750 base compensation received in 1998. This increase provided

6


Mr. Bunger with a compensation package that when combined with an annual incentive award and stock options is competitive with peer company compensation.

      In light of Mobile Mini’s significant 1999 improvement in financial performance over 1998, Mr. Bunger was awarded a cash incentive payment of $281,750 in 1999. The incentive payment was based upon the committee’s evaluation of Mr. Bunger’s contribution to Mobile Mini’s 1999 earnings before taxes, increases in the size of the container rental fleet and lease revenue. During 1999, earnings before one time charges, taxes and extraordinary items increased 111%, rental fleet units increased 44%, and revenues increased 27% over 1998 levels. These results were evaluated based on the overall judgment of the committee with a principal emphasis on the increase in earnings factor in the committee’s evaluation of the performance levels.

      The committee considers long-term incentives, typically in the form of stock options, as an important component of Mobile Mini’s overall executive compensation program. During 1999, Mr. Bunger received stock options on 60,000 shares of Mobile Mini’s common stock. The compensation committee considered Mr. Bunger’s position within Mobile Mini, his contributions to the continuing success of Mobile Mini and the increased value of Mobile Mini, in determining the stock option award.

Compensation of the Chief Executive Officer

      Steven G. Bunger, Mobile Mini’s Chief Executive Officer and President, received a base salary for 1999 of $245,000, an increase from $183,750 in 1998. The increase was a result of Mr. Bunger’s performance as Chief Executive Officer and President during 1999 and is competitive with levels at peer companies.

      In light of Mobile Mini’s significantly improved financial performance over 1998 which is referred to above, Mr. Bunger received a cash incentive payment of $281,750 in 1999.

      During 1999, Mr. Bunger received stock options on 155,000 shares of Mobile Mini’s common stock. The compensation committee considered Mr. Bunger’s contributions to the continuing success and increased value of Mobile Mini in determining the stock option award.

Internal Revenue Code Section 162(m) Compliance

      Internal Revenue Code Section 162(m), enacted in 1993, limits the deductibility of non-performance based compensation in excess of $1 million for certain of Mobile Mini’s executive offices. The non-performance based compensation paid to Mobile Mini’s executive officers in 1999 did not exceed the $1 million limit per officer, nor is it expected that the non-performance based compensation to be paid to Mobile Mini’s executive officers in 2000 will exceed the limit. In 1997, Mobile Mini’s 1994 Stock Option Plan was amended to comply with Section 162(m), and the 1999 Stock Option Plan was prepared so that each plan will qualify as performance based compensation. As such, awards granted under the plans will not be subject to the $1 million limitation.

      Because it is not likely that the cash compensation payable to any of Mobile Mini’s executive officers will exceed the $1 million limitation in the foreseeable future, the committee has decided at this time not to take any other action to limit or restructure the elements of cash compensation payable to Mobile Mini’s executive officers. The committee will reconsider this decision should the individual compensation of any executive officer approach $1 million.

        FOURTH:  The total number of shares of all classes of stock which the Corporation shall have authority to issue is one hundred million (100,000,000) of which ninety-five million (95,000,000) shares shall be common stock with the par value of one cent ($0.01) per share and five million (5,000,000) shares shall be preferred stock with the par value of one cent ($0.01) per share.

Stock Options

      The following table lists our grants during 1999 of stock options to the officers named in the Summary Compensation Table. The amounts shown as potential realizable values rely on arbitrarily assumed rates of share price appreciation prescribed by the Securities and Exchange Commission. In assessing those values, please note that the ultimate value of the options, as well as those shares, depends on actual future share values. Market conditions and the efforts of our directors, officers and others to foster Mobile Mini’s future success can influence those future share values.

Option Grants In Last Fiscal Year

(1)  Includes our contributions to the 401(k) retirement plan.
 
(2)  We provide Richard E. Bunger with the use of a vehicle we own and sold Mr.  Bunger in February 2000, and a $2 million life insurance policy. The amount shown is our estimate of our annual costs paid for the vehicle and the life insurance premiums we paid.
 
(3)  Payments under non-compete agreements with us.

Option Exercises and Year-End Values

      The following table sets forth certain information regarding the exercise and values of options held by the officers named in the Summary Compensation Table, as of December 31, 1999. The table contains values for “in the money” options, meaning a positive spread between the year-end share price of $21.50 and the exercise price. These values have not been, and may never be, realized. The options might never be exercised, and the value, if any, will depend on the share price on the exercise date.

Employment Agreements

      We provide Mr. Richard Bunger with a $2 million life insurance policy, a vehicle and all the employee benefits provided to our executive employees.

      In September 1999 Mobile Mini entered into employment agreements with Steven G. Bunger and Lawrence Trachtenberg. Each agreement has a three year term, and the term automatically renews for additional one year periods unless either we or the employee gives notice of non-renewal. Mr. Bunger’s annual base salary under his employment agreement is $245,000 and Mr. Trachtenberg’s is $175,000. The base salaries may be increased or decreased by the board of directors, but decreases are limited to 15% of the then-current base salary, unless greater decreases are in effect for other Key Executives, as defined in the employment agreements. Each employee is eligible to participate in Mobile Mini’s incentive bonus programs, which are administered by the compensation committee of the board of directors.

      Each employment agreement provides that Mobile Mini will make specified payments to the employee if either the employee’s employment is terminated involuntarily as determined under the agreement, for any reason other than cause (as defined in the employment agreement), or if there is a change of control (as defined in the employment agreement) of Mobile Mini. In the event of any such involuntary termination, the employee would be entitled under the employment agreement to receive a termination payment equal to three times his base salary for the twelve month period preceding the date of termination, and Mobile Mini would have the right to pay that amount over an 18 month period. If within six months after a change in control either the employee is terminated or elects for any reason to terminate his employment, the employee would be entitled to be paid an amount equal to four times the greater of his annual base salary in effect the day before the change of control occurred and his annual base salary during the last twelve months preceding the change of control. This amount would be payable in a lump sum, unless Mobile Mini provided a letter of credit to the employee, in which event the amount could be paid over a period of up to 18 months. Any payment upon termination, however, will be limited to an amount which is less than the “parachute payment” threshold under section 280G of the Internal Revenue Code (currently, $1,000,000).

      Each employment agreement contains provisions restricting the employee’s disclosure and use of Mobile Mini confidential information, and providing that the employee will not compete with Mobile Mini during the

10


18 months following the termination of employment in connection with a change of control and during the three years following termination under any other circumstances.

      Although we have not entered into any long-term employment contracts with any of our other key employees, we have entered into numerous agreements with key employees which are terminable at will, with or without cause, including agreements with Deborah K. Keeley. Each agreement contains a covenant not to compete for a period of two years after termination of employment and a covenant not to disclose confidential information of a proprietary nature to third parties.

      We had numerous bonus and incentive arrangements with several employees during 1999, including Mr. Richard E. Bunger, Mr. Steven G. Bunger, Mr. Trachtenberg, and Ms. Keeley. These agreements included an incentive program to provide financial awards for increases in profitability and based upon a subjective evaluation of performance. Compensation arrangements with Mr. Richard E. Bunger, Mr. Steven G. Bunger and Mr. Lawrence Trachtenberg are administered by the compensation committee of the board of directors.
