ITEM 5. OTHER EVENTS.

         On April 3, 1999, Mobile Mini, Inc. entered into an agreement to
acquire substantially all of the assets of National Security Containers, L.L.C.,
a portable storage leasing company. The closing of this acquisition is subject
to a number of conditions, and is expected to close before the end of April
1999. At the closing of this acquisition, we will pay $17.5 million in cash and
issue shares of redeemable convertible preferred stock valued at $8 million.
However, if certain funding is completed prior to closing this acquisition and
results in net proceeds to us in excess of $16 million, we are obligated to pay
a total of $25.5 million in cash and we will not issue any preferred stock.

         National Security Containers leases portable storage containers from
its nine branches located in Phoenix, Tucson, Dallas, San Antonio, Houston,
Memphis, New Orleans, Denver and Colorado Springs.  We also operate branches in
six of these nine cities and over time we will integrate National Security
Containers' operations with our existing branches in those cities.  Through this
acquisition, we will enter three new markets: Colorado Springs, Memphis and New
Orleans. For the nine month period from April 1, 1998 to December 31, 1998,
National Security Containers had revenues of about $7 million and operating
income of about $1.8 million.


         Effective April 1, 1999, we amended our revolving credit facility to
increase the maximum amount we can borrow from $75 million to $90 million.

               REPRESENTATIONS AND WARRANTIES OF SELLING PARTIES

         Selling Parties, jointly and severally, hereby represent and warrant to
Buyer that the following facts and circumstances as of the date of this
Agreement are true and correct, and hereby acknowledge that such facts and
circumstances constitute the basis upon which Buyer is induced to enter into and
perform this Agreement.

         6.1. Organization; Good Standing and Qualification. Seller is a manager
managed limited liability company duly organized, validly existing and in good
standing under the laws of the State of Arizona, has all necessary powers to
own, lease and operate its assets and properties and to carry on its business as
now owned and operated by it, and is duly qualified to transact business and is
in good standing in all jurisdictions in which the nature of its business or its
properties makes such qualification necessary, except in which the failure to so
qualify would not have a material adverse effect on Seller.

         6.2. Inventory Summary. SCHEDULE 6.2 hereto sets the summary of
Seller's inventory of Storage Units as of February 28, 1999. The summary is in
all material respects a true and complete listing of the Storage Units
identified thereon, and contains the status (i.e., rented or inventory) of such
Storage Unit.

         6.3. No Dealership Agreements. Except as set forth on SCHEDULE 6.3,
Seller is not a party to any agreement, contract or understanding pursuant to
which any person is appointed to be or agreed to serve as a dealer for Seller or
pursuant to which Seller is committed to supply Storage Units on a continuing or
regular basis.

         6.4. Real Property. A true, correct and complete copy of each of the
Real Property Leases has been delivered to Buyer. The Real Property Leases are
valid and in full force, there does not exist any default or event that with
notice or lapse of time, or both, would constitute a material default by Seller
under any of the Real Property Leases, and Selling Parties have no

                                       11
<PAGE>   18
knowledge of any material default or event that with notice or lapse of time, or
both, would constitute a material default by any other party under the Real
Property Leases. Other than Seller's executive offices located at 1001 North
Central Avenue, Phoenix, Arizona, all the buildings, fixtures and leasehold
improvements used by Seller in its Business are located on the Leased Property.
Seller has all right, title and interest of the lessee under the terms of the
Real Property Leases. Except as set forth on SCHEDULE 6.4, no consent is
necessary for the assignment of the Real Property Leases to Buyer and upon the
Closing the Buyer will have all right, title and interest of the lessee under
and subject to the terms of each Real Property Lease, free and clear of all
Liens upon Seller's interest therein.

         6.5. Zoning. To the knowledge of Selling Parties, the zoning of the
Leased Property permits the presently existing improvements, the improvements to
be made under the Real Property Leases, and the operation of Seller's Business
thereon.

         6.6. Storage Units. Except as set forth in SCHEDULE 6.6, all of the
Storage Units which will be conveyed to Buyer hereunder are structurally sound
and are in good repair, reasonable wear and tear excepted. Except as set forth
on SCHEDULE 6.6, the brakes on the Trailer Units have a useful life of at least
25% of their expected life and the tires on the Trailer Units average at least
three-thirty seconds (3/32nds) tread. None of the Storage Units have been
pledged as collateral or are held by the Seller on consignment from others. No
Selling Party holds any sum representing customer deposits with respect to any
Storage Unit except prepaid rentals pursuant to a Contract.

         6.7. Other Tangible Personal Property. The Personal Property described
in Section 1.3 and SCHEDULE 1.3 of this Agreement constitutes all of the items
of tangible personal property owned by, in the possession of, or used by Seller

Personal Property not listed on the schedules hereto (but which is still being
transferred to Buyer at Closing). The Personal Property described in SCHEDULE
1.3 is in good working condition and repair, reasonable wear and tear excepted,
and not in need of maintenance or repairs except for ordinary, routine
maintenance. The Personal Property listed in SCHEDULE 1.3 plus the Storage Units
listed in SCHEDULE 1.2 constitute all material tangible personal property
necessary for the conduct by Seller of its Business as now conducted, except for
the Excluded Assets listed on SCHEDULE 1.13 which otherwise would be included in
the Assets as Personal Property. Except as stated in SCHEDULE 1.3, no Personal
Property used by Seller in connection with its Business is held under any lease,
security agreement, conditional sales contract, or other title retention or
security arrangement, or is in the possession of anyone other than Seller

each Other Agreement is in full force and effect and is enforceable in

actions, response costs, natural resource damages or tort damages; (3) neither
Seller nor, to the knowledge of Seller, any of Seller's predecessors in their
operation of the storage container and trailer business prior to Seller, have
disposed of, transported, recycled, treated or stored Hazardous Materials at any

not been amended, canceled or otherwise modified. The agreements, contracts and
other instruments identified in this Agreement and its Schedules comprise all of
the agreements, contracts and other instruments to which Seller is a party and

thereof in a distribution within the meaning of the Securities Act of 1933, as
amended (the "Securities Act"), and acknowledges that the Shares will not be
transferable by Seller in violation of the Securities Act or the then-applicable
rules or regulations thereunder, provided that Seller may, subject to the
limitations of Section 12.2(a), distribute the Shares to its direct and indirect
members. Buyer has made available to the Selling Parties all of Buyer's public
filings with the Securities and Exchange Commission (the "Commission") and any
and all additional information which any Selling Party has requested concerning
Buyer, its financial condition, results of operations and business prospects.
The Selling Parties further acknowledge that the Shares to be issued as a
portion of the Purchase Price hereunder have not been registered and will not be
registered under the Securities Act or any state securities laws in reliance on
an exemption for private offerings.

         6.24. [Intentionally Omitted].

         6.25. Promotions and Special Offers. Except as set forth on SCHEDULE
6.25, Seller is not a party to any rental, sale, lease purchase or other
arrangement pursuant to which customers may be entitled to special offers or
special pricing relating to any Storage Units. Except as set forth on SCHEDULE
6.25, no customer of Seller has any special or unusual arrangement for the
purchase or lease of any Storage Unit, including, without limitation, any fixed

portions of rental payments may be credited towards the purchase of a Storage
Unit.

         6.26. Future Commitments. Except as set forth on SCHEDULE 6.26, Seller
has not committed to make available to any person or entity any Storage Unit
except pursuant to an existing Contract, and Seller has not committed to make
any Storage Units available to for sale, lease or use at special rates or
without charge to any charity or non-profit organization or event.

         6.27. Receivables. All of the Receivables are the result of bona fide
transactions of the Business in the ordinary course, are valid and enforceable
obligations collectible in accordance with their terms, subject to the reserves
set forth in the Financial Statements and are not subject to any unreserved
offset or counterclaim known to Seller as of the Closing Date. The Receivables
reflected on the audited December 31, 1998 balance sheet and the Closing Balance
Sheet are, or will be, valued and subject to reserves established in accordance
with GAAP. Since November 30, 1998, there have not been any write-offs as
uncollectible of any accounts receivable of the Business, individually in excess
of $100 or in the aggregate, in excess of $2,500. Except as disclosed in
SCHEDULE 6.8, none of the Storage Units have been leased by Seller pursuant to
lease-purchase or similar arrangements.

         6.28. Taxes.

                  (a) All tax and information returns required to be filed by
the Seller, on or prior to the Closing Date with respect to taxes of any kind or
nature have been or will be timely filed, and except as set forth on SCHEDULE

respects. Except as set forth in SCHEDULE 6.28, all amounts owed by Seller
(whether or not shown on any return) as due and payable on each of such returns
for all

                                       20
<PAGE>   27
periods through the Closing Date have been paid or will be paid in full when
due; provided, however, that the representations set forth in this Section 6.28
are made only to the extent that taxes (i) are or may become Liens on the
Assets; (ii) are those for which Buyer may be liable in the capacity of
transferee of the Assets; or (iii) are those for which the non-payment of which
could result, or reasonably could be expected to result, in a material adverse
effect, individually or in the aggregate, on the Assets, the Business or the
financial condition of the Business.

                  (b) Any taxes which were not due and owing will be adequately
reflected on the audited December 31, 1998 balance sheet and will be adequately
reflected on each other balance sheet provided under Section 6.10. Any taxes
which are to be assumed by Buyer in respect of the Assets which at the Closing
Date are not yet due and owing will be adequately reflected on the Final Balance
Sheet as a reserve for taxes. There are no grounds for the assertion or
assessment of any taxes against Seller, the Assets or the Business other than
those reflected or reserved against on balance sheets provided under Section
6.10 or the Closing Balance Sheet.

                  (c) Neither the Assets nor the Business are and will not be
encumbered by any Liens arising out of any unpaid taxes for any period ending on
or prior to the Closing Date, and there are no grounds for the assertion or
assessment of any Liens against the Assets or the Business in respect of any
taxes. The transactions contemplated by this Agreement will not give rise to the
creation of any Liens against the Assets or the Business in respect of any
taxes.

                  (d) Except as set forth in SCHEDULE 6.28, there is no action
or proceeding or unresolved claim for assessment or collection, pending or, to
Seller's knowledge, threatened by, or present or expected dispute with, any
governmental authority for assessment or collection from Seller of any taxes of
any nature affecting Seller, the Assets or the Business.

                  (e) The Seller has withheld and paid or will pay prior to
Closing all taxes required to have been withheld and paid in connection with
amounts paid or owing to any employee, independent contractor, creditor,
manager, member or other third party for any period ending on or prior to the
Closing Date.

         Buyer hereby represents and warrants to Seller that the following facts

Delaware, and has all necessary corporate power to own, lease and operate its
assets and properties and to carry on its business as now owned and operated by
it, and is duly qualified to transact business and is in good standing in all

qualification

                                       23
<PAGE>   30
necessary, except in which the failure to so qualify would not have a material
adverse effect on Buyer.

         7.2. Authority; Non-Contravention; Approvals.

                  (a) Buyer has the right, power and legal capacity and
authority to enter into and perform its obligations under this Agreement, and no
approval or consent of any person (including the stockholders of the Buyer) is
necessary in connection with this Agreement or the transactions contemplated
hereby including but not limited to authorization and issuance of the Shares.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby by Buyer have been, or prior to the Closing
will have been, duly authorized by all necessary corporate action of Buyer and
its stockholders. This Agreement constitutes a legal, valid and binding
obligation of Buyer enforceable against Buyer in accordance with its terms,
except to the extent that enforcement may be limited by bankruptcy, insolvency
or other similar laws affecting creditor's rights generally.

                  (b) Neither the entry into this Agreement nor the consummation
of the transactions contemplated hereby, nor the exercise of any rights and
remedies set forth in the Certificate of Designations for the Series B Preferred
Stock will result in or constitute any of the following: (i) a breach of any
term or provision of this Agreement or the Certificate of Incorporation or
Bylaws of Buyer; (ii) a default or an event that, with notice or lapse of time
or both, would be a default, breach or violation of the certificate of
incorporation or bylaws of Buyer or any lease, license, promissory note,

other agreement, instrument or arrangement to which Buyer is a party or by which
Buyer is are bound; (iii) an event that would permit any party to terminate any
agreement with Buyer or to accelerate the maturity of any indebtedness or other
obligation of Buyer; or (iv) the violation of any law, regulation, ordinance,
judgment, order or decree applicable to or affecting Buyer.

                  (c) Except for the applicable requirements of the HSR Act and
federal and state securities laws, no consent, approval, order or authorization
of, or registration, declaration or filing with, any governmental entity is
required to be obtained or made by or with respect to Buyer or any assets,
properties or operations of Buyer or with respect to the authorization or
issuance of the Series B Preferred Stock or the common stock issuable upon
conversion thereof, in connection with the execution and delivery by Buyer of
this Agreement, the consummation of the transactions contemplated hereby or the
conversion of the Series B Preferred Stock.

         7.3. Valid Issuance of Shares. On or before the Closing Date, (i) the
Buyer will have duly and validly adopted, through all necessary corporate
action, and filed with the Secretary of State of the State of Delaware a
Certificate of Designations for the Series B Preferred Stock containing the
terms and conditions described in Exhibit "A" and which is reasonably acceptable
to Seller, and (ii) the Shares will have been duly authorized and validly
reserved for issuance. Upon the Closing and issuance of the Shares, the Shares
will be duly authorized, validly issued, fully paid and nonassessable shares of
Series B Preferred Stock, and will be free of restrictions on transfer other
than restrictions on transfer under applicable federal and state securities laws

                                       24
<PAGE>   31
and pursuant to Section 12.2(a). There are no preemptive rights with respect to
the Shares, or the shares of the Buyer's common stock issuable upon conversion
of the Shares. On or prior to the Closing Date, the Buyer will have reserved
sufficient number of Shares of its common stock for issuance upon conversion of

Series B Preferred Stock described in Exhibit "A", be duly authorized, validly
issued, fully paid and nonassessable and will be free of restriction on transfer
other than restrictions on transfer under applicable state and federal

without limitation those under the Registration Rights Agreement executed and
delivered by Seller at Closing).

         7.4. Capitalization. The entire authorized capital stock of the Buyer
consists of 22,000,000 shares of stock, of which 17,000,000 shares are
designated common stock, $.01 par value, and 5,000,000 shares are designated
preferred stock, $.01 par value ("Preferred Stock"). As of the Closing Date, no

outstanding shares of capital stock of the Buyer (and any shares issued pursuant
to presently outstanding options, if exercised and purchased at the applicable
exercise price) were duly authorized (or will be when so issued) validly issued,
fully paid and nonassessable.

         7.5. Information. Buyer has made available to the Selling Parties each
registration statement, schedule, report, proxy statement or information
statement it has filed with the Securities and Exchange Commission since January
1, 1998 (collectively, the "Buyer Reports"). To the knowledge of Buyer, none of
the Buyer Reports, taken together with any information disclosed to Buyer in the
Schedules to this Agreement or otherwise in writing, contain any untrue
statement of material fact or omits any material fact necessary in order to make
the statements made, in light of the circumstances under which they are made,
not misleading. Since January 1, 1998, the Buyer has made all filings with the

and costs, that Buyer shall incur or suffer, which arise, result from or relate
to (i) any breach (whether or not material) of, or failure by Selling Parties to
perform, any of their representations, warranties, covenants or agreements in
this Agreement or in any schedule, certificate, exhibit or other instrument
furnished or to be furnished by Selling Parties under this Agreement; (ii) any
relationship, agreement, or dealings between Seller and any of its dealers or
the termination of those relationships; (iii) any failure of the parties to

transfer of the Assets as contemplated by this Agreement or (iv) any Retained
Liabilities (provided, (a) that in the case of Retained Liabilities listed in
Section 4.1(a)(i)(H), such indemnity shall apply only to the extent the Buyer

                                       31
<PAGE>   38
Losses arise from a breach of any representation or warranty in this Agreement,

Section 4.1(a)(i)(F), only the Seller shall be responsible for satisfaction of
the indemnification obligations hereunder and Guarantor shall not be liable to
indemnify Buyer for any Buyer Losses resulting from those Retained Liabilities).
Notwithstanding any of the foregoing indemnification provisions to the contrary,
(i) the Selling Parties shall not be required to make any payments in respect of
their indemnification obligations under this Agreement (except with respect to

above, or arising out of fraud by either Selling Party in connection with this
Agreement or the transaction contemplated by this Agreement ("Seller Fraud"))
unless and until the aggregate amount of the Buyer Losses hereunder exceeds
$100,000 (the "Seller's Basket"), at which time the Buyer shall be entitled to
recover the full amount of all Buyer Losses included in the Seller's Basket
hereunder and all such subsequently incurred Buyer Losses. The aggregate
payments by the Selling Parties in respect of their indemnification obligations
under this Section 11.1 (except for payments made with respect to Buyer Losses

costs and expenses which might become recoverable by Buyer as a result of the

including without limitation those indemnification obligations under Section
11.1. Buyer may, at its option, proceed against the Guarantor for the
performance of any such obligation or agreement, or for damages for default in
the performance thereof, without first proceeding against the Seller or against
any of its properties. The Guarantor further agrees that its guarantee shall be
an irrevocable guarantee and shall continue in effect notwithstanding any

which arise, result from or relate to any breach (whether or not material) of,
or failure by Buyer to perform, any of its representations, warranties,
covenants or agreements in this Agreement or in any schedule, certificate,
exhibit or other instrument furnished or to be furnished by Buyer

under this Agreement. Notwithstanding any of the foregoing indemnification
provisions to the contrary, (i) the Buyer shall not be required to make any
payments in respect of their indemnification obligations under this Agreement
(except with respect to Seller Losses arising out of or related to Buyer's
failure to pay the Purchase Price specified in Section 2.1 or fraud by the Buyer
in connection with this Agreement or the transaction contemplated by this
Agreement ("Buyer Fraud")) unless and until the aggregate amount of the Seller
Losses hereunder exceeds $100,000 (the "Buyer's Basket"), at which time the
Selling Parties shall be entitled to recover the full amount of all Seller
Losses included in the Buyer's Basket hereunder and all such subsequently
incurred Seller Losses. The aggregate payments by the Buyer in respect of its
indemnification obligations under this Section 11.3 (except for payments made
with respect to Seller Losses in connection with Buyer's failure to pay the
Purchase Price specified in Section 2.1 or Buyer Fraud) shall not exceed
$12,500,000 (the "Buyer's Ceiling"). Notwithstanding the limitations imposed by
the Buyer's Basket and Buyer's Ceiling on the Buyer's indemnification
obligations, any Seller Losses incurred by the Selling Parties arising out of

Fraud (a) shall be subject to indemnification by the Buyer without regard to the
Buyer's Basket, (b) shall not be included towards determining whether the

and exclusive remedy against any party hereto for any and all Buyer Losses or
Seller Losses in respect of the matters arising out of this Agreement and the
documents and instruments delivered pursuant hereto other than with respect to
claims which may not be waived under applicable law, which are hereby expressly
reserved.

                             AMENDMENT NUMBER SEVEN
                                       TO
                                CREDIT AGREEMENT


This AMENDMENT NUMBER SEVEN TO CREDIT AGREEMENT (this "Seventh Amendment"),
dated as of March 31, 1999, is entered into by and among MOBILE MINI, INC., a
Delaware corporation (the "Borrower"), each financial institution a party to the
Credit Agreement (collectively, the "Lenders"), and BT COMMERCIAL CORPORATION
acting as agent for the Lenders (in such capacity "Agent"), in light of the
following facts:

                                 R E C I T A L S

A. The parties hereto have previously entered into that certain Credit
Agreement, dated as of March 28, 1996, as amended by that certain Amendment
Number One to Credit Agreement, dated as of November __, 1996, that certain
Amendment Number Two to Credit Agreement, dated as of March 24, 1997, that
certain Amendment Number Three to Credit Agreement, dated as of March 31, 1997,
that certain Amendment Number Four to Credit Agreement, dated as of July 30,
1997, that certain Amendment Number Five to Credit Agreement, dated as of March
31, 1998, and that certain Amendment Number Six to Credit Agreement, dated as of
December 3, 1998 (as amended, the "Agreement").

B. Borrower desires to purchase National Security Containers, L.L.C. for
$25,500,000 (the "Acquisition") and, in conjunction with the Acquisition,
desires to issue up to $8,000,000 in redeemable preferred stock (the "First
Equity Issuance") to fund such Acquisition. The Borrower has informed Agent that
the First Equity Issuance will not be deemed to be debt for purposes of GAAP,
and therefore will not reduce the tangible net worth of Borrower.

C. Borrower further desires to increase the Revolving Credit Commitment under
the Agreement to $90,000,000, and to utilize such funds to partially fund the
Acquisition.

D. Borrower further desires to issue $40,000,000 in common stock in a public
offering (the "Second Equity Issuance"), funds from which the Borrower intends
to redeem the preferred stock issued in the First Equity Issuance and to
partially pay down draws on the Revolving Credit Commitment.

E. Borrower further desires to temporarily increase the total amount of Purchase
Money Liens and Leases (as such term is defined herein) which can be incurred or
maintained by the Borrower pursuant to Section 8.9(d) of the Agreement to
$3,250,000 from and after April 19, 1999 until Borrower receives funds pursuant
to the Second Equity Issuance, at which time the total amount of Purchase Money
Liens and Leases which Borrower may incur or maintain pursuant to Section 8.9(d)
of the Agreement will be permanently reduced back to $1,250,000.

F. Borrower has requested that Agent and all of the Lenders approve amendment of
(i) Section 2.2(a) of the Agreement to reflect such increased Revolving Credit
Commitment and (ii) Section 8.9(d) of the Agreement to reflect such temporary
increase in the total amount of Purchase Money Liens and Leases.

G. Agent and Lenders are, on the terms and conditions set forth herein, willing
to amend the Agreement and grant such consents and waivers.

                                A G R E E M E N T

$1,250,000 and after April 19, 1999, $3,250,000 in the aggregate (irrespective
of when due) outstanding at any one time ("Purchase Money Liens and Leases") so
long as each Purchase Money Lien or Lease shall attach or relate only to the
property to be acquired or the acquisition cost of which is financed through
leasing, a description shall have been furnished to the Agent for any item of
equipment for which the purchase price (whether payable by Borrower or the
lessor thereof) is greater than $50,000 and the principal amount of the debt
incurred (including the principal component of lease payments) shall not exceed
one hundred percent (100%) of the purchase price of the item or items of
equipment, provided, however, upon the receipt by Borrower of proceeds, whether
cash or otherwise, in connection with the Second Equity Issuance (as defined in
Amendment Number Seven to Credit Agreement, dated March 31, 1999) Borrower's
ability to incur and maintain Indebtedness pursuant to this Section 8.9(d) shall
be limited to $1,250,000."

4.       Amendment of Annex I. Annex I of the Agreement is hereby amended by

         and replacing such amounts as follows:

Tempe, AZ - April 5, 1999 -- Mobile Mini, Inc. (NASDAQ National Market: MINI)

Headquartered in Phoenix, NSC currently operates nine portable storage leasing

Separately, Mobile Mini also announced that it has commenced operations in
Tulsa, Oklahoma utilizing its low-cost start-up business model.

Separately, the Company announced that its senior lenders, led by BT Commercial
Corporation, have agreed to increase the Company's revolving line of credit by
20%, to $90 million from $75 million. Richard Bunger, Chairman of the Board,
noted, "Twice in 1998 and again this year, we fortified our balance sheet by
increasing the amount of borrowing available to us. By expanding our credit line
to $90 million, we have a strong ally in our bankers who have expressed their
confidence in our continued ability to identify and consummate suitable
acquisitions while growing existing locations and our lease fleet."

Commenting, Steven Bunger, Mobile Mini's President and Chief Executive Officer
said, "With the Tulsa opening and this acquisition, Mobile Mini will have a
total of 16 locations. The four newly added markets are contiguous with our
existing locations. NSC, whose business model is similar to ours, has been a
strong competitor in our overlapping markets. This acquisition improves our
market share in those territories and gives us the potential for economies of
scale as we integrate NSC's locations into those of our own."

According to Larry Trachtenberg, Executive Vice President and Chief Financial
Officer, "NSC, a former Mobile Mini dealer, has built the highest quality rental
fleet, after our own, that we have encountered among our competitors and peers.
One of our stated goals has been to enter four to eight new markets in 1999.
With our entry in Tulsa, along with this acquisition, our largest ever, Mobile
Mini has already reached the minimum threshold of that goal."

Mobile Mini, Inc. is a market leader in the leasing of portable storage
containers.
