                           MTI TECHNOLOGY CORPORATION

                          Common Stock Purchase Warrant

                           (Void after July __, 2016)

     MTI Technology Corporation, a Delaware corporation (the "Company"), for
value received, hereby certifies that _______________ (the "Registered Holder"),
is entitled, subject to the terms and conditions set forth below, to purchase
from the Company, at any time or from time to time during the period beginning
July __, 2007 and ending at 5:00 p.m. (Pacific time) on July __, 2017 (the
"Exercise Period"), Three Hundred Thousand (300,000) shares of Common Stock,
$0.001 par value per share, of the Company ("Common Stock"). The purchase price
shall be $1.32 per share. The shares purchasable upon exercise of this Warrant,
and the purchase price per share, each as adjusted from time to time pursuant to
the provisions of this Warrant, are hereinafter referred to as the "Warrant
Shares" and the "Purchase Price," respectively. For purposes of this Warrant,
"Warrant Issue Date" shall mean the date on which this Warrant was first issued,
regardless of any subsequent transfer or partial exercise of this Warrant that
may occur after such date.

     1. Exercise

          (a) Exercise for Cash. The Registered Holder may, at its option, elect
     to exercise this Warrant, in whole or in part and at any time or from time
     to time during the Exercise Period, by surrendering this Warrant, with the
     purchase form appended hereto as Exhibit I duly executed by or on behalf of
     the Registered Holder, at the principal office of the Company, or at such
     other office or agency as the Company may designate, accompanied by payment
     in full, in lawful money of the United States, of the Purchase Price
     payable in respect of the number of Warrant Shares purchased upon such
     exercise.



          (b) Cashless Exercise

               (i) The Registered Holder may, at its option, elect to exercise
          this Warrant, in whole or in part and at any time or from time to time
          during the Exercise Period, on a cashless basis, by surrendering this
          Warrant, with the purchase form appended hereto as Exhibit I duly
          executed by or on behalf of the Registered Holder, at the principal
          office of the Company, or at such other office or agency as the
          Company may designate, by canceling a portion of this Warrant in
          payment of the Purchase Price payable in respect of the number of
          Warrant Shares purchased upon such exercise. In the event of an
          exercise pursuant to this subsection 1(b), the number of Warrant
          Shares issued to the Registered Holder shall be determined according
          to the following formula:

                                     Y(A-B)
                                 X = ------
                                        A

          Where: X = the number of Warrant Shares that shall be issued to the
                     Registered Holder pursuant to the cashless exercise;

                 Y = the number of Warrant Shares for which this Warrant is
                     being exercised (which shall include both the number of
                     Warrant Shares issued to the Registered Holder and the
                     number of Warrant Shares subject to the portion of the
                     Warrant being cancelled in payment of the Purchase Price);

                 A = the Fair Market Value (as defined below) of one share of
                     Common Stock; and

                 B = the Purchase Price then in effect.

               (ii) For purpose of this Warrant, "Fair Market Value" per share
          of Common Stock shall be determined as follows:

                    (A) If the Common Stock is listed on a national securities
               exchange, the Nasdaq Capital Market or another nationally
               recognized trading system as of the Exercise Date, the Fair
               Market Value per share of Common Stock shall be deemed to be the
               average of the high and low reported sale prices per share of
               Common Stock thereon on the five (5) trading days immediately
               preceding (and not including) the Exercise Date.

                    (B) If as of the Exercise Date the Common Stock is not
               listed on a national securities exchange, the Nasdaq Capital
               Market or another nationally recognized trading system as of the
               Exercise Date, the Fair Market Value per share of Common Stock
               shall be deemed to be the amount most recently determined by the
               Board of Directors of the Company (the "Board") to represent the
               fair market value per share of the Common Stock (including a
               determination for purposes of granting Common Stock options or
               issuing Common Stock under any plan,


                                      -2-



               agreement or arrangement with employees of the Company); and,
               upon request of the Registered Holder, such Board (or a
               representative thereof) shall, as promptly as reasonably
               practicable but in any event not later than five (5) days after
               such request, notify the Registered Holder of the Fair Market
               Value per share of Common Stock and furnish the Registered Holder
               with reasonable documentation of such Board's determination of
               such Fair Market Value. Notwithstanding the foregoing, if the
               Board has not made such a determination within the three-month
               period prior to the Exercise Date, then (a) the Board shall make,
               and shall provide or cause to be provided to the Registered
               Holder notice of, a determination of the Fair Market Value per
               share of the Common Stock within fifteen (15) days of a request
               by the Registered Holder that it do so, and (b) the exercise of
               this Warrant pursuant to this subsection 1(b) shall be delayed
               until such determination is made and notice thereof is provided
               to the Registered Holder.

          (c) Exercise Date. Each exercise of this Warrant shall be deemed to
     have been effected immediately prior to the close of business on the day on
     which this Warrant shall have been surrendered to the Company as provided
     in subsection 1(a) or 1(b) above (the "Exercise Date"). At such time, the
     person or persons in whose name or names any certificates for Warrant
     Shares shall be issuable upon such exercise as provided in subsection 1(d)
     below shall be deemed to have become the holder or holders of record of the
     Warrant Shares represented by such certificates.

          (d) Issuance of Certificates. As soon as practicable after the
     exercise of this Warrant in whole or in part, and in any event within three
     (3) Trading Days (as defined below) thereafter, the Company, at its
     expense, shall cause to be issued in the name of, and delivered to, the
     Registered Holder, or as the Registered Holder (upon payment by the
     Registered Holder of any applicable transfer taxes) may direct:

               (i)  a certificate or certificates for the number of full Warrant
                    Shares to which the Registered Holder shall be entitled upon
                    such exercise plus, in lieu of any fractional share to which
                    the Registered Holder would otherwise be entitled, cash in
                    an amount determined pursuant to Section 3 below; and

               (ii) in case such exercise is in part only, a new warrant or
                    warrants of like tenor, calling in the aggregate on the face
                    or faces thereof for the number of Warrant Shares equal
                    (without giving effect to any adjustment therein) to the
                    number of such shares called for on the face of this Warrant
                    minus the number of Warrant Shares for which this Warrant
                    was so exercised.

     For purposes of this Warrant, "Trading Day" shall mean (a) any day on which
     quotations or listings with respect to the Common Stock are provided on the
     Nasdaq Capital Market or another nationally recognized quotation or trading
     system or (b) if the Common Stock is not then listed or quoted on the
     Nasdaq Capital Market or another nationally recognized trading system, then
     a day on which trading occurs on the New York Stock Exchange (or any
     successor thereto).


                                      -3-



     2. Adjustments

          (a) Adjustment for Stock Splits and Combinations. If the Company shall
     at any time or from time to time after the Warrant Issue Date (i) effect a
     subdivision of the outstanding shares of Common Stock (whether by stock
     split, stock dividend or otherwise), or (ii) combine the outstanding shares
     of Common Stock (whether by reverse stock split or otherwise), the Purchase
     Price in effect immediately before that subdivision or combination shall be
     proportionately adjusted. Any adjustment under this paragraph shall become
     effective concurrently with the effectiveness of the applicable subdivision
     or combination of the outstanding shares of Common Stock. Notwithstanding
     Section 13 hereof or the foregoing, in the event (a) the Company effects a
     split of the Common Stock by means of a stock dividend and the Purchase
     Price of and the number of Warrant Shares are adjusted as of the date of
     the distribution of the dividend (rather than as of the record date for
     such dividend) and (b) the Registered Holder exercises this Warrant between
     the record date and the distribution date for such stock dividend, the
     Registered Holder shall be entitled to receive, on the distribution date,
     the stock dividend with respect to the shares of Common Stock acquired upon
     such exercise, notwithstanding the fact that such shares were not
     outstanding as of the close of business on the record date for such stock
     dividend.

          (b) Adjustments for Dividends and Other Distributions. In the event
     the Company at any time or from time to time after the Warrant Issue Date
     shall make or issue, or fix a record date for the determination of holders
     of Common Stock entitled to receive, a dividend or other distribution
     payable in shares of Common Stock or other securities of the Company or in
     cash or other property, then, and in each such event, the Registered Holder
     shall receive upon exercise hereof, in addition to the number of shares of
     Common Stock to be received upon such exercise, the kind and amount of
     securities of the Company, cash or other property that they would have been
     entitled to receive had this Warrant been exercised (without use of the
     cashless exercise provisions) for shares of Common Stock immediately prior
     to such event and had they thereafter, during the period from the date of
     such event to and including the exercise date, retained such securities,
     giving application to all adjustments called for during such period under
     this paragraph with respect to the rights of the Registered Holder.

          (c) Adjustment for Merger or Reorganization, etc. If there shall occur
     any reorganization, recapitalization, reclassification, consolidation or
     merger involving the Company in which the Common Stock is converted into or
     exchanged for securities, cash or other property (other than a transaction
     covered by Subsections 2(a) or 2(b)), then, following any such
     reorganization, recapitalization, reclassification, consolidation or
     merger, this Warrant shall be exercisable in accordance with its terms into
     the kind and amount of securities, cash or other property that a holder of
     the number of shares of Common Stock of the Company issuable upon exercise
     of this Warrant immediately prior to such reorganization, recapitalization,
     reclassification, consolidation or merger would have been entitled to
     receive pursuant to such transaction; and, in such case, appropriate
     adjustment (as determined in good faith by the Board) shall be made in the
     application of the provisions in this Warrant with respect to the rights
     and interests thereafter of the Registered Holder, to the end that the
     provisions set forth in this Warrant (including provisions with respect to
     changes in and other adjustments of the Purchase Price) shall


                                      -4-



     thereafter be applicable, as nearly as reasonably may be, in relation to
     any securities or other property thereafter deliverable upon the exercise
     of this Warrant.

          (d) Rounding of Calculations. All calculations under this Warrant
     shall be made to the nearest whole number of shares, with five tenths (0.5)
     of a share rounded up. The number of shares of Common Stock outstanding at
     any given time shall not include shares owned or held by or for the account
     of the Company, and the disposition of any such shares shall be considered
     an issue or sale of Common Stock.

          (e) Certificate as to Adjustments. Upon the occurrence of each
     adjustment pursuant to this Warrant, the Company at its expense will
     promptly compute such adjustment in accordance with the terms hereof and
     prepare a certificate describing in reasonable detail such adjustment and
     the transactions giving rise thereto, including all facts upon which such
     adjustment is based. The Company will promptly deliver a copy of each such
     certificate to the Registered Holder and to the Company's Transfer Agent.
     The Company shall, as promptly as reasonably practicable after the written
     request at any time of any Registered Holder (but in any event not later
     than ten (10) days thereafter), furnish or cause to be furnished to such
     Registered Holder a certificate setting forth (i) the Purchase Price then
     in effect, and (ii) the number of shares of Common Stock and the amount, if
     any, of other securities, cash or property that then would be received upon
     the exercise of this Warrant.

     3. Fractional Shares. The Company shall not be required upon the exercise
of this Warrant to issue any fractional shares, but shall pay the value thereof
to the Registered Holder in cash on the basis of the Fair Market Value per share
of Common Stock.

     4. Compliance with Securities Laws; Investment Representations.

          (a) The Registered Holder is acquiring the Warrant for investment and
     not with a view to the resale or distribution of the Warrant or the Warrant
     Shares, or any interest therein, without prejudice, however, to the
     Registered Holder's right, subject to compliance with the Asset Purchase
     Agreement dated June 6, 2006 between the Company and the Registered Holder
     (the "Asset Purchase Agreement"), at all times to sell or otherwise dispose
     of all or any part of such Warrant or Warrant Shares pursuant to an
     effective registration statement under the Securities Act or under an
     exemption from such registration and in compliance with applicable federal
     and state securities laws. Nothing contained herein shall be deemed a
     representation or warranty by the Registered Holder to hold any of the
     Warrant or Warrant Shares for any period of time. The Registered Holder is
     acquiring the Warrant hereunder in the ordinary course of business. Except
     as contemplated by the Asset Purchase Agreement, the Registered Holder has
     no agreement, undertaking, arrangement, obligation or commitment providing
     for the disposition of such Warrant or Warrant Shares. The Registered
     Holder has not been organized, reorganized or recapitalized specifically
     for the purpose of investing in the Purchased Securities. At all times
     since the time the Registered Holder was initially offered the Warrant,
     such Purchaser has been an "accredited investor" as such term is defined in
     Regulation D under the Securities Act of 1933, as amended.


                                      -5-



          (b) The Registered Holder has substantial experience in evaluating and
     investing in private placement transactions of securities in companies
     similar to the Company so that it is capable of evaluating the merits and
     risks of its investment in the Company and has the capacity to protect its
     own interests. The Registered Holder will bear the economic risk of this
     investment until the Warrant or Warrant Shares are registered pursuant to
     the Securities Act, or an exemption from registration is available.

          (c) Unless a registration statement under the Act is effective with
     respect to the Warrant Shares to be issued upon the exercise of this
     Warrant, the certificate representing such Warrant Shares shall bear the
     following legend, in addition to any legend imposed by applicable state
     securities laws:

               THE SHARES OF COMMON STOCK EVIDENCED BY THIS CERTIFICATE HAVE NOT
               BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
               APPLICABLE STATE SECURITIES LAWS. THESE SHARES MAY NOT BE SOLD,
               OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
               EFFECTIVE REGISTRATION STATEMENT UNDER SAID ACT AND APPLICABLE
               STATE SECURITIES LAWS, OR AN OPINION OF COUNSEL REASONABLY
               SATISFACTORY TO MTI TECHNOLOGY CORPORATION THAT SUCH REGISTRATION
               IS NOT REQUIRED.

     5. Transfers, etc.

          (a) The Company shall maintain a register containing the name and
     address of the Registered Holder of this Warrant. The Registered Holder may
     change its address as shown on the warrant register by written notice to
     the Company requesting such change.

          (b) Subject to the provisions of this Section 5 and the Asset Purchase
     Agreement, this Warrant and all rights hereunder are transferable, in whole
     or in part, upon surrender of this Warrant with a properly executed
     assignment (in the form of Exhibit II hereto) at the principal office of
     the Company (or, if another office or agency has been designated by the
     Company for such purpose, then at such other office or agency); provided,
     however, that any such transfer must be in compliance with all applicable
     federal and state securities laws and must include the delivery to the
     Company of representations of the transferee substantially similar to those
     set forth in Section 4 hereof and, if this Warrant or any rights hereunder
     are sold, pledged or hypothecated in whole or in part, legal opinions with
     respect thereto in a form reasonably satisfactory to the Company, if such
     are requested by the Company; and provided, further, that notwithstanding
     the foregoing, no such legal opinions shall be requested by the Company in
     connection with any transfer by the Registered Holder to Pencom Systems,
     Incorporated or by Pencom Systems, Incorporated to Edward Ateyeh, Jr., Wade
     Saadi or Edgar Saadi.

     6. Remedies. Nothing herein shall limit a Registered Holder's right to
pursue any other remedies available to it hereunder, at law or in equity,
including a decree of specific performance


                                      -6-



and/or injunctive relief with respect to the Company's failure to timely deliver
certificates representing shares of Common Stock upon exercise of this Warrant
as required pursuant to the terms hereof.

     7. Repurchase on Sale, Merger, or Consolidation of the Company.

          (a) Acquisition. For the purpose of this Warrant, "Acquisition" means
     any sale, license, or other disposition of all or substantially all of the
     assets (including intellectual property) of the Company, or any
     reorganization, consolidation, or merger of the Company where the holders
     of the Company's securities before the transaction beneficially own less
     than fifty percent (50%) of the outstanding voting securities of the
     surviving entity after the transaction. This Warrant shall become fully
     exercisable immediately prior to the closing of any Acquisition that occurs
     within one (1) year from the date hereof notwithstanding that the Exercise
     Period shall not have commenced as of such time.

          (b) Assumption of Warrant. If upon the closing of any Acquisition the
     successor entity assumes the obligations of this Warrant, then this Warrant
     shall be exercisable for the same securities, cash, and property as would
     be payable for the shares of Common Stock issuable upon exercise of the
     unexercised portion of this Warrant as if such shares were outstanding on
     the record date for the Acquisition and subsequent closing. The Exercise
     Price shall be adjusted accordingly. With respect to any Acquisition in
     which successor entity stock is issued as part or all of the consideration
     to be received by the Company or its securityholders in connection with
     such Acquisition, the Company shall use commercially reasonable efforts to
     require such successor entity to assume the obligations of this Warrant.

          (c) Nonassumption. If upon the closing of any Acquisition the
     successor entity does not assume the obligations of this Warrant and the
     Registered Holder has not otherwise exercised this Warrant in full, then
     the unexercised portion of this Warrant shall be deemed to have been
     automatically converted pursuant to Section 1(b) and thereafter the
     Registered Holder shall participate in the Acquisition on the same terms as
     other holders of the same class of securities of the Company.

     8. Charges, Taxes and Expenses. The Company shall pay any and all issue and
other similar taxes that may be payable in respect of any issuance or delivery
of shares of Common Stock upon exercise of this Warrant. The Company shall not,
however, be required to pay any tax that may be payable in respect of any
transfer involved in the issuance and delivery of Warrant Shares or Warrants in
a name other than that in which this Warrant is registered.

     9. Reservation of Stock. The Company shall at all times reserve and keep
available, solely for issuance and delivery upon the exercise of this Warrant,
such number of Warrant Shares and other securities, cash and/or property, as
from time to time shall be issuable upon the exercise of this Warrant. If the
number of shares of Common Stock so reserved is insufficient, in addition to any
other remedy available to the Registered Holder, the Company shall take any
corporate action that is necessary to make available a sufficient number of
authorized but unissued and otherwise unreserved shares of Common Stock within
sixty (60) days after the occurrence of such deficiency.


                                      -7-



     10. Obtaining Approvals and Listings. The Company will, at its own expense,
obtain and keep effective any and all permits, consents and approvals of
governmental agencies and authorities which may from time to time be required of
the Company in order to issue shares of Common Stock upon the exercise of the
Warrants and otherwise to perform its obligations hereunder, except, in each
case, for any such permits, consents and approvals (other than those relating to
blue sky laws) required as a result of the status of a Registered Holder of the
Warrants. The Company will, at its expense, obtain promptly and maintain the
approval for listing on the Nasdaq Capital Market or any successor thereto or
comparable system, upon official notice of issuance, the shares of Common Stock
issuable upon exercise of the then outstanding Warrants and maintain the listing
or quoting of such shares after their issuance so long as the Common Stock is so
listed or quoted.

     11. Exchange or Replacement of Warrants

          (a) Upon the surrender by the Registered Holder, properly endorsed, to
     the Company at the principal office of the Company, the Company shall,
     subject to the provisions of Section 5 above, issue and deliver to or upon
     the order of the Registered Holder, at the Company's expense, a new Warrant
     or Warrants of like tenor, in the name of the Registered Holder or as the
     Registered Holder (upon payment by the Registered Holder of any applicable
     transfer taxes) may direct, calling in the aggregate on the face or faces
     thereof for the number of shares of Common Stock (or other securities, cash
     and/or property) then issuable upon exercise of this Warrant.

          (b) Upon receipt of evidence reasonably satisfactory to the Company of
     the loss, theft, destruction or mutilation of this Warrant and (in the case
     of loss, theft or destruction) upon delivery of an indemnity agreement to
     the Company, or (in the case of mutilation) upon surrender and cancellation
     of this Warrant, the Company will issue, in lieu thereof, a new Warrant of
     like tenor.

     12. Notices. All notices and other communications from the Company to the
Registered Holder in connection herewith shall be mailed by certified or
registered mail, postage prepaid, or sent via a reputable nationwide overnight
courier service guaranteeing next business day delivery, to the address last
furnished to the Company in writing by the Registered Holder. All notices and
other communications from the Registered Holder to the Company in connection
herewith shall be mailed by certified or registered mail, postage prepaid, or
sent via a reputable nationwide overnight courier service guaranteeing next
business day delivery, to the Company at its principal office. If the Company
should at any time change the location of its principal office to a place other
than its current principal office, it shall give prompt written notice to the
Registered Holder and thereafter all references in this Warrant to the location
of its principal office at the particular time shall be as so specified in such
notice. All such notices and communications shall be deemed delivered (a) two
(2) business days after being sent by certified or registered mail, return
receipt requested, postage prepaid, or (b) one (1) business day after being sent
via a reputable nationwide overnight courier service guaranteeing next business
