Non-Transferability of Stock Purchase Right.
--------------------------------------------

         This Stock Purchase Right may not be transferred in any manner other
than by will or by the laws of descent or distribution and may be exercised
during the lifetime of Purchaser only by Purchaser. The terms of the Plan and
this Agreement shall be binding upon the executors, administrators, heirs,
successors and assigns of the Purchaser.

II.      AGREEMENT
         ---------

         1. Sale of Stock. The Company hereby agrees to sell to the Purchaser,
and the Purchaser hereby agrees to purchase the number of Shares set forth above
in the Notice of Grant of Stock Purchase Right, at the exercise price per share
set forth in the Notice of Grant of Stock Purchase Right (the "Exercise Price"),
and subject to the terms and conditions of the Plan, which is incorporated
herein by reference. Subject to Section 14(c) of the Plan, in the event of a
conflict between the terms and conditions of the Plan and this Agreement, the
terms and conditions of the Plan shall prevail.

         2. Payment of Purchase Price. Purchaser herewith (i) delivers to the
Company the aggregate Exercise Price for the Shares by promissory note ("Note")
in the form of Exhibit A hereto, (ii) pledges the Shares to the Company to
secure the Note pursuant to a Pledge

<PAGE>

Agreement in the form of Exhibit B attached hereto and (iii) assigns the Shares
pursuant to an Assignment Separate From Certificate in the form of Exhibit B-1.

         3. Purchaser's Representations. In the event the Shares have not been
registered under the Securities Act of 1933, as amended, at the time this Stock
Purchase Right is exercised, the Purchaser shall, if required by the Company,
concurrently with the exercise of all or any portion of this Stock Purchase
Right, deliver to the Company his or her Investment Representation Statement in
the form attached hereto as Exhibit C.

         4. Repurchase Option.

         (a) In the event the Purchaser's continuous status as an independent
consultant ("Service Provider") terminates for any or no reason (including death
or Disability), the Company shall, upon the date of such termination (as
reasonably fixed and determined by the Company), have an irrevocable, exclusive
option (the "Repurchase Option") for a period of sixty (60) days from such date
to repurchase up to that number of shares which constitute the Unvested Shares
(as defined in Section 5) at the Exercise Price per share, plus interest at the
rate of interest set forth in the Note (the "Repurchase Price").

         (b) The Repurchase Option shall be exercised by the Company by
delivering written notice to the Purchaser or the Purchaser's executor (with a
copy to the Escrow Holder (as defined in Section 7)) and, at the Company's
option, (i) by delivering to the Purchaser or the Purchaser's executor a check
in the amount of the aggregate Repurchase Price, or (ii) by the Company
canceling an amount of the Purchaser's indebtedness to the Company equal to the
aggregate Repurchase Price, or (iii) by a combination of (i) and (ii) so that
the combined payment and cancellation of indebtedness equals such aggregate
Repurchase Price. Upon delivery of such notice and the payment of the aggregate
Repurchase Price in any of the ways described above, the Company shall become
the legal and beneficial owner of the Unvested Shares being repurchased and all
rights and interests therein or relating thereto, and the Company shall have the
right to retain and transfer to its own name the number of Unvested Shares being
repurchased by the Company.

         (c) Whenever the Company shall have the right to repurchase the
Unvested Shares hereunder, the Company may designate and assign one or more
employees, officers, directors or shareholders of the Company or other persons
or organizations to exercise all or a part of the Company's Repurchase Option to
purchase all or a part of the Unvested Shares. If the Fair Market Value of the
Unvested Shares to be repurchased on the date of such designation or assignment
(the "Repurchase FMV") exceeds the aggregate Repurchase Price of the Unvested
Shares, then each such designee or assignee shall pay the Company cash equal to
the difference between the Repurchase FMV and the aggregate Repurchase Price of
Unvested Shares to be purchased.

                                       2

<PAGE>

         (d) If the Company or its assignee does not elect to exercise the
Repurchase Option conferred above by giving the requisite notice within sixty
(60) days following Purchaser's termination as a Service Provider, the
Repurchase Option shall terminate.

         5. Release of Shares From Repurchase Option (Vesting).

         (a) All of the Shares purchased pursuant to this Agreement shall be
released from the Repurchase Option (sometimes hereafter referred to as "vest"
or "vesting") on January 1, 2002, provided that if the Consulting Agreement,
dated as of the date hereof, between the Purchaser and the Company (the
"Consulting Agreement") is terminated on June 30, 2001 in accordance with its
terms, then 37,500 Shares shall vest on June 30, 2001.

         (b) Any of the Shares which have not yet been released from the
Company's Repurchase Option are referred to herein as "Unvested Shares."

         (c) In the event that Purchaser's relationship as a Service Provider
with the Company shall terminate prior to the vesting of all Shares purchased
under this Agreement all Unvested Shares shall cease to vest pursuant to this
Agreement.

         6. Restriction on Transfer. Except for the escrow described in Section
7 of this Agreement or transfer of the Shares to the Company or its assignees
contemplated by this Agreement or the Pledge Agreement (in the form attached
hereto as Exhibit B), none of the Shares or any beneficial interest therein
shall be transferred, encumbered or otherwise disposed of in any way until the
release of such Shares from the Company's Repurchase Option in accordance with
the provisions of this Agreement, other than by will or the laws of descent and
distribution; provided, however, that Purchaser may transfer shares in
conformance with Section 8(f) of this Agreement.

         7. Escrow of Shares.

         (a) To ensure the availability for delivery of the Purchaser's Unvested
Shares upon exercise of the Repurchase Option by the Company, the Purchaser
shall, upon execution of this Agreement, deliver and deposit with an escrow
holder designated by the Company (the "Escrow Holder") and reasonably acceptable
to the Purchaser the share certificates representing the Unvested Shares,
together with the Assignment Separate from Certificate (the "Stock Assignment")
duly endorsed in blank, in the form attached hereto as Exhibit D. The Unvested
Shares and Stock Assignment shall be held by the Escrow Holder, pursuant to the
Joint Escrow Instructions of the Company and Purchaser in the form attached as
Exhibit E hereto, until such time as the Company's Repurchase Option expires.

         (b) The Escrow Holder shall not be liable for any act it may do or omit
to do with respect to holding the Unvested Shares in escrow and while acting in
good faith and in the exercise of its judgment.

                                       3

<PAGE>

         (c) If the Company or any assignee exercises its Repurchase Option
hereunder, the Escrow Holder, upon receipt of written notice of such option
exercise from the proposed transferee, shall take all steps necessary to
accomplish such transfer.

         (d) When the Repurchase Option has been exercised or expires
unexercised, and a portion of the Shares has been released from such Repurchase
Option, the Escrow Holder shall promptly upon request, but not more frequently
than once each year, cause a new certificate to be issued for such released
Shares and shall deliver such certificate to the Company or the Purchaser, as
the case may be.

         (e) Subject to the terms hereof, the Purchaser shall have all the
rights of a shareholder with respect to such Shares while they are held in
escrow, including without limitation, the right to vote the Shares and receive
any cash dividends declared thereon. If, from time to time during the term of
the Company's Repurchase Option, there is (i) any stock dividend, stock split or
other change in the Shares, or (ii) any merger or sale of all or substantially
all of the assets or other acquisition of the Company, any and all new,
substituted or additional securities to which the Purchaser is entitled by
reason of the Purchaser's ownership of the Shares shall be immediately subject
to this escrow, deposited with the Escrow Holder and included thereafter as
"Shares" for purposes of this Agreement and the Company's Repurchase Option.

         8. Company's Right of First Refusal. Before any Shares held by
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

         (a) Notice of Proposed Transfer. The Holder of the Shares shall deliver
to the Company a written notice (the "Notice") stating: (i) the Holder's bona
fide intention to sell or otherwise transfer such Shares; (ii) the name of each
proposed purchaser or other transferee ("Proposed Transferee"); (iii) the number
of Shares to be transferred to each Proposed Transferee; and (iv) the bona fide
cash price or other consideration for which the Holder proposes to transfer the
Shares (the "Offered Price"), and the Holder shall offer the Shares at the
Offered Price to the Company or its assignee(s).

         (b) Exercise of Right of First Refusal. At any time within thirty (30)
days after receipt of the Notice, the Company and/or its assignee(s) may, by
giving written notice to the Holder, elect to purchase all or part of the Shares
proposed to be transferred to any one or more of the Proposed Transferees, at
the purchase price determined in accordance with subsection (c) below.

         (c) Purchase Price. The purchase price ("Purchase Price") for the
Shares purchased by the Company or its assignee(s) under this Section shall be
(i) the Offered Price in the case of Shares that are vested or (ii) in the case
of Shares that are Unvested Shares, the lower

                                       4

<PAGE>

of the Offered Price or the Repurchase Price as defined in Section 4(a) hereof.
If the Offered Price includes consideration other than cash, the cash equivalent
value of the non-cash consideration shall be determined by the Board of
Directors of the Company in good faith.

         (d) Payment. Payment of the Purchase Price shall be made, at the option
of the Company or its assignee(s), (i) by cash or check, (ii) by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or (iii) by any
combination thereof within thirty (30) days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

         (e) Holder's Right to Transfer. If Shares proposed in the Notice to be
transferred to a given Proposed Transferee are not purchased by the Company
and/or its assignee(s) as provided in this Section, then the Holder may sell or
otherwise transfer such Shares, that are not repurchased by the Company, to that
Proposed Transferee at the Offered Price or at a higher price, provided that
such sale or other transfer is consummated within one hundred twenty (120) days
after the date of the Notice and provided further that any such sale or other
transfer is effected in accordance with any applicable securities laws and the
Proposed Transferee agrees in writing that the provisions of this Section shall
continue to apply to the Shares in the hands of such Proposed Transferee. If the
Shares described in the Notice are not transferred to the Proposed Transferee
within such period, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

         (f) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section notwithstanding, the transfer of any or all of the
Shares during the Purchaser's lifetime or on the Purchaser's death by will or
intestacy to the Purchaser's Immediate Family or a trust for the benefit of one
or more members of the Purchaser's Immediate Family or to a trust, partnership,
limited liability company, custodianship or other fiduciary account for the
benefit of the Purchaser or one or more members of the Purchaser's Immediate
Family, or the disbursement therefrom to Purchaser or one or more members of his
Immediate Family, shall be exempt from the provisions of this Section, provided
that the Purchaser notifies the Company in writing within thirty (30) days of
said transfer. "Immediate Family" as used herein shall mean spouse, lineal
descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Agreement, including but not limited to this
Section and Section 4, and there shall be no further transfer of such Shares
except in accordance with the terms of this Section.

         (g) Termination of Right of First Refusal. The Right of First Refusal
shall terminate as to any Shares upon the date of the first sale of Common Stock
of the Company to the general public pursuant to a registration statement filed
with and declared effective by the Securities and Exchange Commission under the
1933 Act.

         9. Restrictive Legends; Stop-Transfer Orders; Refusal to Transfer.

                                       5

<PAGE>

         (a) Purchaser understands and agrees that the Company shall cause the
legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares together with
any other legends that may be required by the Company or by applicable state or
federal securities laws:

          THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE
          OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR
          HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN
          THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE
          SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR
          HYPOTHECATION IS IN COMPLIANCE THEREWITH.

          THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
          CERTAIN RESTRICTIONS ON TRANSFER, A RIGHT OF FIRST REFUSAL,
          AND A REPURCHASE OPTION HELD BY THE ISSUER OR ITS ASSIGNEE(S)
          AS SET FORTH IN THE RESTRICTED STOCK PURCHASE AGREEMENT
          BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A
          COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE
          ISSUER. SUCH TRANSFER RESTRICTIONS, RIGHT OF FIRST REFUSAL AND
          REPURCHASE OPTION ARE BINDING ON TRANSFEREES OF THESE SHARES.

         (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

         (c) Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

         10. Lock-Up Period. Purchaser hereby agrees that, if so requested by
the Company or any representative of the underwriters (the "Managing
Underwriter") in connection with any registration of the offering of any
securities of the Company under the Securities Act, Purchaser (or any transferee
under Section 8 of this Agreement) shall not sell or otherwise transfer any
Shares or other securities of the Company during the 180-day period (or such
shorter period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the

                                       6

<PAGE>

Company) (the "Market Standoff Period") following the effective date of a
registration statement of the Company filed under the Securities Act. Such
restriction shall apply only to the first registration statement of the Company
to become effective under the Securities Act that includes securities to be sold
on behalf of the Company to the public in an underwritten public offering under
the Securities Act. The Company may impose stop-transfer instructions with
respect to securities subject to the foregoing restrictions until the end of
such Market Standoff Period.

         11. Tax Consequences. Set forth below is a brief summary as of the date
of grant of this Stock Purchase Right of some of the federal tax consequences of
exercise of this Stock Purchase Right and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE.

         (a) Exercise of Stock Purchase Right. Generally, no income will be
recognized by Purchaser in connection with the exercise of the stock purchase
right for shares subject to the Repurchase Option, unless an election under
Section 83(b) of the Code is filed with the Internal Revenue Service within 30
days of the date of exercise of the right to purchase stock. The form for making
this election is attached as Exhibit F hereto. Otherwise, as the Company's
repurchase right lapses, Purchaser will recognize compensation income in an
amount equal to the difference between the Fair Market Value of the stock at the
time the Company's repurchase right lapses and the amount paid for the stock, if
any (the "Spread"). If Purchaser is a Service Provider or former Service
Provider, the Spread will be subject to tax withholding by the Company, and the
Company will be entitled to a tax deduction in the amount at the time the
Purchaser recognizes ordinary income with respect to a Stock Purchase Right.

         (b) Disposition of Shares. Upon disposition of the Shares, any gain or
loss is treated as capital gain or loss. If the Shares are held for more than
one year, any gain realized on disposition of the shares will be treated as
long-term capital gain for federal income tax purposes. Long-term capital gains
are grouped and netted by holding periods. Net capital gains on assets held for
more than 12 months is capped at 20%. Capital losses are allowed in full against
capital gains, and up to $3,000 against other income.

         THE PURCHASER ACKNOWLEDGES THAT IT IS THE PURCHASER'S SOLE
RESPONSIBILITY AND NOT THE COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION
83(b), EVEN IF THE PURCHASER REQUESTS THE COMPANY OR ITS REPRESENTATIVES TO MAKE
THIS FILING ON THE PURCHASER'S BEHALF.

         12. No Guarantee of Continued Service. PURCHASER ACKNOWLEDGES AND
AGREES THAT THE RELEASE OF SHARES FROM THE REPURCHASE OPTION OF THE COMPANY
PURSUANT TO PARAGRAPH 5 HEREOF IS EARNED ONLY BY CONTINUING SERVICE AS SERVICE
PROVIDER (NOT THROUGH THE ACT OF BEING HIRED OR PURCHASING SHARES HEREUNDER).
PURCHASER FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS
CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN

                                       7

<PAGE>

DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A
SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL.

         13. Notices. Any notice, demand or request required or permitted to be
given by either the Company or the Purchaser pursuant to the terms of this
Agreement shall be in writing and may be delivered by hand, by nationally
recognized private courier, or by certified mail. Notices delivered by hand or
by nationally recognized private courier shall be deemed given when delivered
personally to the addressee or to the courier, or if given by certified mail
when deposited in the U.S. mail, certified and with postage prepaid, and
addressed to the parties at the addresses of the parties set forth at the end of
this Agreement or such other address as a party may request by notifying the
other in writing.

             Any notice to the Escrow Holder shall be sent to the Company's
address with a copy to the other party not sending the notice.

         14. No Waiver. Either party's failure to enforce any provision or
provisions of this Agreement shall not in any way be construed as a waiver of
any such provision or provisions, nor prevent that party from thereafter
enforcing each and every other provision of this Agreement. The rights granted
both parties herein are cumulative and shall not constitute a waiver of either
party's right to assert all other legal remedies available to it under the
circumstances.

         15. Successors and Assigns. The Company may assign any of its rights
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

         16. Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Administrator which shall review such dispute at its next regular meeting. The
resolution of such a dispute by the Administrator shall be final and binding on
all parties.

         17. Governing Law; Severability. This Agreement is governed by the
internal substantive laws, but not the choice of law rules, of New York.

         18. Entire Agreement. The Plan is incorporated herein by reference.
This Agreement (including the exhibits referenced herein), the Plan and the
Investment Representation Statement constitute the entire agreement of the
parties with respect to the subject matter hereof and supersede in their
entirety all prior undertakings and agreements of the Company and Purchaser with
respect to the subject matter hereof, and may not be modified adversely to the
Purchaser's interest except by means of a writing signed by the Company and
Purchaser.

         shall forthwith become due and payable upon without presentment,
         demand, protest, or other notice of any kind, all of which are
         expressly waived.

                  b. Non-Waiver and Other Remedies. No course of dealing or
delay on the part of the holder of this Note in exercising any right hereunder
shall operate as a waiver thereof or otherwise prejudice the rights of the
holder of this Note. No remedy conferred hereby shall be exclusive of any other
remedy referred to herein or now or hereafter available at law, in equity, by
statute or otherwise.

         2.       Security.

                  (a) Pledge Agreement. This Note is secured by a Pledge
Agreement between the Payor and the Payee, dated of even date herewith (the
"Pledge Agreement"), pursuant to which the Payor has pledged the Common Stock as
collateral for payment hereunder.

                  (b) Recourse. No recourse under or upon any obligation,
covenant or agreement of this Note, or for any claim based hereon or otherwise
in respect hereof, shall be had against the Payor or his assigns, except (i) for
accrued and unpaid interest, and (ii) in the event the amount actually applied
to the payment of principal of this Note after payment of costs and expenses and
accrued but unpaid interest hereon upon any sale by the Payee of the Common
Stock (or any other collateral held as security for this Note) pursuant to
Section 3 of the Pledge Agreement, or otherwise, is less than the original
principal amount hereof, then this Note shall be with recourse to the Payor as
to accrued and unpaid interest hereon, and to not more than thirty three and
one-third percent (33 1/3 %) of the principal remaining unpaid immediately prior
to such application.

         3.       Prepayment. The indebtedness evidenced by this Note may be
prepaid by the Payor at any time in whole or in part from time to time, without
premium or penalty, provided that any prepayment of any portion of the
outstanding principal amount hereof shall be accompanied by all accrued but
unpaid interest thereon.

         4.       Lost Documents. Upon receipt by the Payor of evidence
reasonably satisfactory to him of the loss, theft, destruction or mutilation of
this Note or any Note exchanged for it, and (in the case of loss, theft or
destruction) of indemnity reasonably satisfactory to him, and upon reimbursement
to the Payor of all reasonable expenses incidental thereto, and upon surrender
and cancellation of such Note, if mutilated, the Payor will make and deliver to
the Payee in lieu of such Note a new Note of like tenor and unpaid principal
amount and dated as of the original date of this Note.

         5.       No Presentment, etc. The Payor and any endorsers, sureties and
guarantors of this Note waive presentment for payment, demand, protest, notice
of protest and notice of dishonor hereof, and all other notices to which they
may be entitled.

         6.       Miscellaneous.
                  a. Parties in Interest. All covenants, agreements and
undertakings in this Note by and on behalf of any of the parties hereto shall
bind and inure to the benefit of the respective permitted successors and assigns
of the parties hereto whether so expressed or not.

                  b. Notices. All notices, requests, consents and demands shall
be made in writing and shall be sent, and deemed delivered, in the manner
prescribed in Paragraph 12 of the Pledge Agreement.

                  c. Waiver. The failure of the Payee to exercise any right or
remedy granted to him hereunder on any one or more instances, shall not
constitute a waiver of any default by the

<PAGE>

Payee, and all such rights and remedies shall remain continuously in force. No
delay or omission in the exercise or enforcement by the Payee of any rights or
remedies shall be construed as a waiver of any right or remedy of the Payee; and
no exercise or enforcement of any such right or remedy shall be held to exhaust
any other right or remedy of the Payee.

                  d. Illegality. If any one or more of the provisions contained
in this Note shall for any reason be held to be invalid, illegal or
unenforceable, such invalidity, illegality or unenforceability shall not affect
any other provisions of this Note and this Note shall be construed as if such
invalid, illegal or unenforceable provision had never been contained herein.

                  e. Amendment. This Note may not be changed orally, but only by
an instrument in writing duly executed by the party against which enforcement of
any waiver, change, modification or discharge is sought.

                  f. Construction. This Note shall be construed and enforced in
accordance with, and the rights of the parties shall be governed by, the laws of
the State of New York.

                                    ---------

                                PLEDGE AGREEMENT

         THE PLEDGE AGREEMENT (the "Agreement"), entered into as of
____________, 2001, by and between Nexsan Corporation ("Secured Party") and
__________ (the "Pledgor").

                              W I T N E S S E T H:

         WHEREAS, Pledgor has purchased from the Secured Party
______________shares ("Shares") of the common stock of Corporation, a Delaware
corporation (the "Corporation"), pursuant to the Restricted Stock Purchase
Agreement and exhibits thereto (collectively the "Agreement"), dated the date
hereof between Pledgor and the Secured Party ("Stock Purchase Agreement"); and

         WHEREAS, Pledgor has agreed to pledge the Shares as security for the
Promissory Note of even date herewith, made by Pledgor to the order of the
Secured Party pursuant to the Stock Purchase Agreement (the "Note").

         NOW, THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1. Warranty and Covenant. Pledgor represents and warrants to the
Secured Party that except for the security interest created hereby, and except
for restrictions imposed by the Restricted Stock Purchase Agreement, he owns the
Shares free and clear of all liens, charges and encumbrances and that he has the
unencumbered right to pledge such Shares pursuant to the terms hereof.

         2. Pledge. As security for the prompt payment and performance when due
(whether at stated maturity, by acceleration or otherwise) of all indebtedness
and all other liabilities and obligations, whether now existing or hereafter
arising, of Pledgor to the Secured Party under or arising out of the Note
(collectively, the "Obligations"), Pledgor hereby delivers, pledges and assigns
to Secured Party and creates in Secured Party a perfected first security
interest in all of Pledgor's right, title and interest in, to and under all of
the Shares, together with (subject to the terms of Section 3 hereof) all rights
and privileges of Pledgor with respect thereto, all proceeds, income and profits
thereof and all property received in addition thereto, in exchange thereof or in
substitution therefor and in any other property or assets of equal value as may
from time to time be substituted by mutual agreement of the parties hereto as
collateral security hereunder (all such property of Pledgor being hereinafter
referred to collectively as the "Collateral").

<PAGE>

         3. Rights of Pledgor. So long as no Default has occurred and is
continuing (as used, herein, the term "Default" shall mean and include (i) the
failure of Pledgor to perform any of her Obligations when due, (ii) any material
misrepresentation by Pledgor in or with respect to any provision of the
Agreement or the Note, or (iii) any attachment of the Collateral at any time
pursuant to any court order or other legal process), (a) Pledgor shall be
entitled to vote or consent with respect to the Collateral in any manner not
inconsistent with the Agreement or the Note, and (b) all cash distributions with
respect to the Shares shall, anything in Section 2 or elsewhere herein to the
contrary notwithstanding, be the sole and exclusive property of Pledgor.

         4. Event of Default. In the event of the occurrence of an Event of
Default, as such term is defined in the Note, and the continuation of such Event
of Default uncured beyond any applicable notice or other grace period, Secured
Party may sell or otherwise dispose of the Collateral at a public or private
sale or make other commercially reasonable disposition of the Collateral or any
portion thereof after twenty-one (21) calendar days' notice to the Pledgor. Any
proceeds of the disposition of the Collateral in excess of the then outstanding
Obligations shall promptly be remitted to Pledgor by the Secured Party.

                  If any consent, approval or authorization of any state,
municipal or other governmental department, agency or authority should be
necessary to effectuate any sale or other disposition of the Collateral, or any
partial disposition of the Collateral, Pledgor agrees to execute all such
applications and other instruments as may be required in connection with
securing any such consent, approval or authorization, and will otherwise use her
reasonable best efforts to secure the same. Pledgor further agrees to use her
reasonable best efforts (without incurring any additional cost or expense) to
secure such sale or other disposition of the Collateral as the Secured Party may
deem necessary pursuant to the terms of the Agreement

         5. Additional Rights of the Secured Party. In addition to its rights
and privileges under the Agreement, the Secured Party shall have all the rights,
powers and privileges of a secured party under the Uniform Commercial Code as in
effect in any applicable jurisdiction.

         6. Binding Agreement. The Agreement shall be construed and interpreted
in accordance with the internal laws of the State of New York applicable to
agreements made and to be performed wholly within the State of New York. The
Agreement, together with all documents referred to herein, constitutes the
entire agreement between the parties with respect to the matters addressed
herein and may not be modified except by a writing executed by Pledgor and the
Secured Party.

         7. Covenants. The Secured Party covenants that, provided no Default or
Event of Default (as defined in the Note) shall exist and be continuing, it
shall release Shares from the pledge created hereby upon payment of a pro rata
portion of the Note and accrued interest; provided, that such Shares shall be
delivered by Secured Party to the Escrow Holder (as defined in the Stock
Purchase Agreement) to be held and disposed of in accordance with the terms of
the Stock Purchase Agreement.

                                       2

<PAGE>

         8. Termination. The Agreement shall continue in full force and effect
until all the Obligations shall have been fully and indefeasibly paid in full.
The Collateral shall be delivered to the Escrow Holder upon full payment,
satisfaction and termination of all of the Obligations, to be held and disposed
of in accordance with the terms of the Agreement.

         9. Further Assurances. Pledgor shall at any time and from time to time
upon the written request of the Secured Party, execute and deliver such further
documents and do such further acts and things as the Secured Party may
reasonably request in order to effect the purposes of the Agreement.

         10. Severability. If any paragraph herein, or part thereof, shall for
any reason be held or adjudged to be invalid, illegal or unenforceable by any
court of competent jurisdiction, such paragraph or part thereof so adjudicated
invalid, illegal or unenforceable shall be deemed separate, distinct and
independent, and the remainder of the Agreement shall remain in full force and
effect and shall not be affected by such holding or adjudication.

         11. Successors and Assigns. The Agreement, and the terms and conditions
hereof, shall be binding upon and shall inure to the benefit of the Pledgor and
his or her successors and assigns, and the Secured Party and his or her
successors and assigns; provided that Pledgor may not assign or delegate his or
her obligations hereunder without the prior written consent of the Secured Party
and any purported assignment or delegation by Pledgor of his or her obligations
hereunder in the absence of such written consent shall be void.

         12. Notices. All notices and other communication provided for herein
shall be in writing and mailed, by registered or certified mail, return receipt
requested, or delivered by overnight courier or by hand, to the intended
recipient at the "Address for Notices" specified below intended recipient's name

together shall constitute a single instrument.

                       INVESTMENT REPRESENTATION STATEMENT

PURCHASER:    ________________________
COMPANY:      Nexsan Corporation
SECURITY:     COMMON STOCK
AMOUNT:       _______________ shares
DATE:         _________________

         In connection with the purchase of the above-listed shares of common
stock (the "Securities"), the undersigned Purchaser represents to the Company
the following:

         Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Purchaser is
acquiring these Securities for investment for Purchaser's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

         Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein. In this connection, Purchaser understands
that, in the view of the Securities and Exchange Commission, the statutory basis
for such exemption may be unavailable if Purchaser's representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale,
for or until an increase or decrease in the market price of the Securities, or
for a period of one (1) year or any other fixed period in the future. Purchaser
further understands that the Securities must be held indefinitely unless they
are subsequently registered under the Securities Act or an exemption from such
registration is available. Purchaser further acknowledges and understands that
the Company is under no obligation to register the Securities. Purchaser
understands that the certificate evidencing the Securities will be imprinted
with a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel
satisfactory to the Company, a legend prohibiting their transfer without the
consent of the Commissioner of Corporations of the State of Delaware and any
other legend required under applicable state securities laws.

         Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Stock Purchase Right to the Purchaser, the
exercise will be exempt from

                                       1

<PAGE>

registration under the Securities Act. In the event the Company becomes subject
to the reporting requirements of Section 13 or 15(d) of the Securities Exchange
Act of 1934, ninety (90) days thereafter (or such longer period as any market
stand-off agreement may require) the Securities exempt under Rule 701 may be
resold, subject to the satisfaction of certain of the conditions specified by
Rule 144, including: (1) the resale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934); and,
in the case of an affiliate, (2) the availability of certain public information
about the Company, (3) the amount of Securities being sold during any three (3)
month period not exceeding the limitations specified in Rule 144(e), and (4) the
timely filing of a Form 144, if applicable.

         In the event that the Company does not qualify under Rule 701 at the
time of grant of the Stock Purchase Right, then the Securities may be resold in
certain limited circumstances subject to the provisions of Rule 144, which
requires the resale to occur not less than one (1) year after the later of the
date the Securities were sold by the Company or the date the Securities were
sold by an affiliate of the Company, within the meaning of Rule 144; and, in the
case of acquisition of the Securities by an affiliate, or by a non-affiliate who
subsequently holds the Securities less than two (2) years, the satisfaction of
the conditions set forth in sections (1), (2), (3) and (4) of the paragraph
immediately above.

         Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

Signature of Purchaser:

Dear Sir:

         As Escrow Agent for both Nexsan Corporation, a Delaware corporation
(the "Company"), and the undersigned purchaser of stock of the Company (the
"Purchaser"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to the terms of that certain Restricted Stock Purchase
Agreement ("Agreement") between the Company and the undersigned, in accordance
with the following instructions:

         a.      In the event the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the "Company") exercises the
Company's repurchase option set forth in the Agreement (the "Repurchase
Option"), the Company shall give to Purchaser and you a written notice
specifying the number of shares of stock to be purchased, the purchase price,
and the time for a closing hereunder at the principal office of the Company.
Purchaser and the Company hereby irrevocably authorize and direct you to close
the transaction contemplated by such notice in accordance with the terms of said
notice.

         b.      At the closing, you are directed (i) to date the stock
assignments necessary for the transfer in question, (ii) to fill in the number
of shares being transferred, and (iii) to deliver same, together with the
certificate evidencing the shares of stock to be transferred, to the Company or
its assignee, against the simultaneous delivery to you of the purchase price (by
cash, a check, or some combination thereof) for the number of shares of stock
being purchased pursuant to the exercise of the Repurchase Option.

         c.      Purchaser irrevocably authorizes the Company to deposit with
you any certificates evidencing shares of stock to be held by you hereunder and
any additions to and substitutions for said shares as defined in the Agreement.
Purchaser does hereby irrevocably constitute and appoint you as Purchaser's
attorney-in-fact and agent for the term of this escrow to execute with respect
to such securities all documents necessary or appropriate to make such
securities negotiable and to complete any transaction herein contemplated,
including but not limited to the filing with any applicable state blue sky
authority of any required applications for consent to, or notice of transfer of,
the securities. Subject to the provisions of this paragraph (c), Purchaser shall
exercise all rights and privileges of a shareholder of the Company while the
stock is held by you.

                                       1

<PAGE>

         d.      Once per calendar year and upon termination of this escrow,
unless the Repurchase Option has been exercised, you will deliver to Purchaser a
certificate or certificates representing so many shares of stock as are not then
subject to the Repurchase Option. Within ninety (90) days after cessation of
Purchaser's continuous service - rendering to the Company, or any parent or
subsidiary of the Company, you will deliver to Purchaser a certificate or
certificates representing the aggregate number of shares held or issued pursuant
to the Agreement and not purchased by the Company or its assignees pursuant to

assigns. Executive represents, warrants and acknowledges that he has carefully
read this Section 5, that he has had an opportunity to have the provisions
contained herein explained to him by his attorney, and that he understands the
provisions contained herein. Executive further acknowledges that, by reason of
his training, skills, experience and employment hereunder, the services to be
rendered by him under the provisions of this Agreement and their value to the
Company are of a special, unique and extraordinary character and that it would
be difficult or impossible to replace such services, and he further acknowledges
that a violation by him of any of the provisions of this Section 5 could cause
continuing material and irreparable injury to the Company and that in such event
money damages would not be readily calculable and the Company would not have an
adequate remedy at law. Executive acknowledges and agrees that (i) the
restrictions under this Section 5 are reasonable and will not interfere with
Executive's ability to earn a livelihood or impose upon him any undue hardship,
and (ii) any breach of the covenants, provisions and restrictions contained in
this Section 5 shall cause, and shall be deemed to be, a fundamental and
material breach of Executive's fiduciary and contractual obligations to
Employer. Therefore, Executive agrees that the Company shall be authorized and
entitled to obtain from any court of competent jurisdiction, interim and
permanent equitable relief, including without limitation, injunctive relief, in
the event of any such breach or threatened breach of the provisions of this
Section 5, together with payment of reasonable attorneys' fees and disbursements
and any other costs of enforcement incurred in connection with such breach or
threatened breach. These rights and remedies shall be cumulative and shall be in
addition to any other rights or remedies whatsoever to which the Company shall
otherwise be entitled hereunder, at

                                     - 6 -

<PAGE>

law or otherwise, including the right to seek damages (including any
consequential damages) which any court of competent jurisdiction may deem
appropriate.

construction, validity and performance, be governed by and construed and
enforced in accordance with the laws of the State of New York. Except as

not resolved thereby, shall be settled by arbitration, before a single
arbitrator sitting in New York, New York or any other location mutually
agreeable to the parties, in accordance with the Commercial Arbitration Rules of
the American Arbitration Association, and judgment upon the award rendered by

shall also be authorized to award damages and costs. Notwithstanding the
foregoing, in the extent of a breach or impending breach of this Agreement,
either party may seek an injunction, restraining order or other equitable relief
from any court of competent jurisdiction.

      7. SUCCESSORS

         This Agreement and all rights of Executive hereunder shall inure to the
benefit of and be enforceable by Executive's personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and
legatees. If Executive should die while any amounts still are payable to him
hereunder if he had continued to live, all such amounts, unless otherwise
provided herein, shall be paid in accordance with the terms of this Agreement to
Executive's devisee, legatee, or other designee or, if there be no such
designee, to Executive's estate.
