  in consideration of the agreements herein and in reliance upon the representations and warranties set forth herein and therein, the
  parties agree as follows:

  estate, right, title and interest of Wits Basin in and to the Collateral as more fully described on Exhibit
  A hereto, whether now owned or later acquired or created, and including
  all proceeds of the Collateral, whether cash or non-cash (the “Collateral”).
  

      2.2      FINANCING
  STATEMENTS. 

           (a)
  Wits Basin hereby authorizes Secured Party to file all financing statements,
  continuation statements, assignments, certificates, and other documents and instruments with respect to the Collateral pursuant to the
  UCC and otherwise as may be necessary or reasonably requested by Secured Party to perfect or from time to time to publish notice of,
  or continue or renew the security interests granted hereby (including, such financing statements, continuation statements, certificates,
  and other documents as may be necessary or reasonably requested to perfect a security interest in any additional property rights hereafter
  acquired by Wits Basin or in any replacements, products or proceeds thereof), in each case in form and substance satisfactory to Secured
  Party. 

           (b)
  Secured Party will pay the cost of filing the same in all public offices where
  filing is necessary or reasonably requested by Secured Party and will pay any and all recording, transfer or filing taxes that may due

  or sufficiency of any payment received by their or present or file any claim, or take any action to collect or enforce the payment of
  any amounts which may have been assigned to them or to which they may be entitled at any time or times.

  any default by Wits Basin under any of the Constituent Documents shall occur, Secured Party shall, at its option, be permitted (but
  shall not be obligated) to remedy any such default by giving written notice of such intent to Wits Basin and to the parties to such
  agreement. Any cure by Secured Party of Wits Basin’s default under a Constituent Document shall not be construed as an assumption
  by Secured Party of any obligations, covenants or agreements of Wits Basin under the Constituent Documents, and Secured Party shall
  not incur any liability to Wits Basin or any other person as a result of any actions undertaken by Secured Party in curing or attempting
  to cure any such default. This Agreement shall not be deemed to release or to affect in any way the obligations of Wits Basin under
  any of the Constituent Documents.

  RIGHTS AND REMEDIES 

      5.1      EVENT
  OF DEFAULT DEFINED. Any event of default under the Note or, if issued,
  under the Supplemental Note (including events of non-compliance with this Agreement, as described in the Note or, if issued, the Supplemental
  Note) shall constitute an "Event of Default"
  hereunder. 

      5.2     
  REMEDIES UPON EVENT OF DEFAULT.
  

           (a) During any period
  during which an Event of Default shall have occurred and be continuing, Secured Party may (but shall be under no obligation to), directly
  or by using agent or broker:

                (i)
  proceed to protect and enforce the rights vested in it by this Agreement and
  under the UCC; 

                (ii)
  cause all moneys and other property pledged as security to be paid and/or delivered
  directly to it, and demand, sue for, collect and receive any such moneys and property; 

                (iii)
  cause any action at law or suit in equity or other proceeding to be instituted
  and prosecuted to collect or enforce any Obligations of Wits Basin or rights included in the Collateral, or for specific enforcement
  of any covenant or agreement contained herein, or in aid of the exercise of any power therein or herein granted, or for any foreclosure
  hereunder and sale under a judgment or decree in any judicial proceeding, or to enforce any other legal or equitable right vested in
  it by this Agreement or by law; 

 -6- 

                (iv)
  foreclose or enforce any other agreement or other instrument by or under or
  pursuant to which the Obligations of Wits Basin are issued or secured; 

                (v)
  subject to Section
  5.2(b), sell, lease or otherwise dispose of any or all of the Collateral,
  in one or more transactions, at such prices as Secured Party may deem best, and for cash or on credit or for future delivery, without
  assumption of any credit risk, at any broker’s board or at public or private sale, without demand of performance or notice of intention
  to sell, lease or otherwise dispose of, or of time or place of disposition (except such notice as is required by applicable statute
  and cannot be waived), it being agreed that Secured Party may be purchasers or lessees on their own behalf at any such sale and that
  Secured Party or anyone else who may be the purchaser, lessee or recipient for value of any or all of the Collateral so disposed of
  shall, upon such disposition, acquire all of Wits Basin’s rights therein. Secured Party may adjourn any public or private sale
  or cause the same to be adjourned from time to time by announcement at the time and place fixed for the same, and such sale may, without
  further notice or publication, be made at any time or place to which the same may be so adjourned. If Secured Party sell any of the
  Collateral upon credit, after reasonable inquiry as to the credit worthiness of the purchaser, Wits Basin will be credited only with
  payments actually made by the purchaser, received by Secured Party and applied to the indebtedness of the purchaser. In the event the
  purchaser fails to pay for the Collateral, Secured Party may resell the Collateral and Wits Basin shall be credited with the proceeds
  of the sale; 

                (vi)
  incur expenses, including reasonable attorneys’ fees, consultants’
  fees, and other costs appropriate to the exercise of any right or power under this Agreement; 

                (vii)
  perform any obligation of Wits Basin hereunder and make payments, purchase,
  contest or compromise any encumbrance, charge, or lien, and pay taxes and expenses; 

                (viii)
  make any reasonable compromise or settlement deemed desirable with respect
  to any or all of the Collateral and extend the time of payment, arrange for payment installments, or otherwise modify the terms of,
  any or all of the Collateral; 

                (ix)
  secure the appointment of a receiver of any or all of the Collateral; 

                (x)
  exercise any other or additional rights or remedies granted to Secured Party
  under any other provision of this Agreement or exercisable by a secured party under the UCC, whether or not the UCC applies to the affected
  Collateral, or under any other applicable law and take any other action which Secured Party deem necessary or desirable to protect or
  realize upon their security interests in the Collateral or any part thereof; and/or

 -7-

                (xi)
  appoint a third party (who may be an employee, officer or other representative
  of Secured Party) to do any of the foregoing, or take any other action permitted hereunder, on behalf of Secured Party. 

           (b)
  If, pursuant to any law, prior notice of any action described in Section
  5.2(a) is required to be given to Wits Basin, Wits Basin hereby acknowledges
  that the minimum time required by such law, or if no minimum is specified, ten days, shall be deemed a reasonable notice period. 

           (c)
  Any action or proceeding to enforce this Agreement may be taken by Secured
  Party either in Wits Basin’s name or in Secured Party’s name, as Secured Party may deem necessary. 

           (d)
  All rights of marshalling of assets of Wits Basin, including any such right
  with respect to the Collateral, are hereby waived by Wits Basin. 

           (e)
  Secured Party shall incur no liability as a result of the sale of any or all
  of the Collateral at any private sale pursuant to Section 5.2(a)
  conducted in a commercially reasonable manner. Wits Basin hereby waives any claims against Secured Party arising by reason of the fact
  that the price at which any or all of the Collateral may have been sold at such a private sale was less than the price that might have
  obtained at a public sale or was less than the aggregate amount of the Obligations, even if Secured Party accept the first offer received
  and does not offer the Collateral to more than one offeree. 

      5.3     
  ATTORNEY-IN-FACT.
  Upon the occurrence and during the continuation of an Event of Default, Wits Basin hereby irrevocably constitutes and appoints Secured
  Party as its true and lawful attorney-in-fact to enforce all rights of Wits Basin with respect to the Collateral, including the right
  to give appropriate receipts, releases and satisfactions for and on behalf of and in the name of Wits Basin or, at the option of Secured
  Party, in the name of Secured Party, with the same force and effect as Wits Basin could do if this Agreement had not been made. If Secured
  Party shall so elect after the occurrence and during the continuation of an Event of Default hereunder, Secured Party shall have the
  right at all times to settle, compromise, adjust, or liquidate all claims or disputes directly with Wits Basin or any obligor of Wits
  Basin upon such terms and conditions as Secured Party may determine in its sole discretion, and to charge all costs and expenses thereof
  (including reasonable attorneys’ fees and charges) to Wits Basin’s account and to add them to the Obligations whereupon such
  costs and expenses shall be and become part of the Obligations. This power of attorney is a power coupled with an interest and shall
  be irrevocable. 

      5.4     
  EXPENSES; INTEREST.
  All costs and expenses (including reasonable attorneys’ fees and expenses) incurred by Secured Party in connection with exercising
  any actions taken under Article 5, together with interest thereon (to the extent permitted by law) computed at a rate of 10% per annum
  (or if less, the maximum rate permitted by law) from the date on which such costs or expenses are invoiced to and become payable by
  Wits Basin, to the date of payment thereof, shall constitute part of the Obligations secured by this Agreement and shall be paid by
  Wits Basin to Secured Party within 10 days after written demand. 

 -8- 

 

      5.5     
  NO IMPAIRMENT OF REMEDIES.
  If under applicable law, Secured Party proceed by either judicial foreclosure or by non-judicial sale or enforcement, Secured Party
  may, at its sole option, determine which of its remedies or rights to pursue without affecting any of their rights and remedies under
  this Agreement. If, by exercising any right and remedy, Secured Party forfeits any of its other rights or remedies, including any right
  to enter a deficiency judgment against Wits Basin or any third party (whether because of any applicable law pertaining to “election
  of remedies” or the like), Wits Basin nevertheless hereby consents to such action by Secured Party. To the extent permitted by
  applicable law, Wits Basin also waives any claim based upon such action, even if such action by Secured Party results in a full or partial
  loss of any rights of subrogation, indemnification or reimbursement which Wits Basin might otherwise have had but for such action by
  Secured Party or the terms herein. Any election of remedies which results in the denial or impairment of the right of Secured Party
  to seek a deficiency judgment against any third party shall not, to the extent permitted by applicable law, impair Wits Basin’s
  obligations hereunder. If Secured Party bids at any foreclosure or trustee’s sale or at any private sale permitted by law or this
  Agreement, Secured Party may bid all or less than the amount of the Obligations. To the extent permitted by applicable law, the amount
  of the successful bid at any such sale, whether Secured Party or any other party is the successful bidder, shall be conclusively deemed
  to be the fair market value of the Collateral and the difference between such bid amount and the remaining balance of the Obligations
  shall be conclusively deemed to be the amount of the Obligations. 

 ARTICLE 6.

  OF OBLIGATIONS. Wits Basin’s liability hereunder shall not be reduced,

  assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of,
  any claim or demand or any right, power or remedy (whether arising under any Loan Document, at law, in equity or otherwise) with respect
  to any of the Obligations or any agreement relating thereto, or with respect to any other guaranty of or security for the payment of
  any of the Obligations;

            THIS CERTIFIES THAT, for value received, ________________ (the

the common stock (the "Shares") of Dtomi, Inc. (the "Company"), at an exercise
price of $.18 per share (the "Exercise Price"), subject to the terms and
conditions set forth herein.

Warrant may be exercised by the Holder, in part or in whole, by the surrender of
this Warrant (with the notice of exercise form attached hereto as Exhibit A duly
executed) at the principal office of the Company, and by the payment to the
Company, by certified, cashier's or other check acceptable to the Company or by
wire transfer to an account designated by the Company, of an amount equal to the
Exercise Price of the Shares being purchased, at any time before 5:00 P.M.,
E.S.T., on December 31, 2006, unless the Warrant has been called, pursuant to
Section 1(b) herein, in which case it shall expire at 5:00 P.M., E.S.T., on the

            (b) Warrant Call. The Company may call the Warrant at any time after
the closing bid price for the common stock of the Company has been at or above
$0.60 per share for five (5) consecutive trading days, regardless of whether an
SB-2 Registration Statement has been filed or declared effective by the U.S.
Securities and Exchange Commission (the "SEC").

                  (i) The Warrant shall expire forty-five (45) days from the

investor as follows:

-------------------------------------------------------------------------------
     DATE REGISTRATION STATEMENT                 ADDITIONAL WARRANT TO PURCHASE
                                                        COMMON STOCK AS A
                                                        % OF THE WARRANT
          BECOMES EFFECTIVE                           INCLUDED IN THE UNITS
-------------------------------------------------------------------------------
Between July 15, 2003 and January 31, 2004                     0%
Between February 1, 2004, and February 29, 2004                6%
Between March 1, 2004 and March 31, 2004                       9%
April 1, 2004 and thereafter                                  12%
-------------------------------------------------------------------------------

            (c) The Company shall use its best efforts to keep the Registration
Statement effective until December 31, 2006.

            (d) After the Registration Statement becomes effective, the
investors may publicly sell the Shares of Common Stock issuable upon exercise of
the Warrant.

            (e) The cost of the registration of the Registrable Securities will
be at the Company's expense, except for the Investor's attorney's fees which
shall be borne by the Investor.

      4. Adjustments. Subject to the provisions of Section 5 hereof, the number
and kind of securities purchasable upon the exercise of this Warrant and the
Exercise Price therefor shall be subject to adjustment from time to time upon
the occurrence of certain events, as follows:

            (a) Reclassification. In the case of any reclassification or change
of securities of the class issuable upon exercise of this Warrant (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination), or in case of any
merger of the Company with or into another corporation (other than a merger with
another corporation in which the Company is the acquiring and the surviving
corporation and which does not result in any reclassification or change of
outstanding securities issuable upon exercise of this Warrant), or in case of
any sale of all or substantially all of the assets of the Company, the Company,
or such successor or purchasing corporation, as the case may be, shall duly
execute and deliver to the holder of this Warrant a new Warrant (in form and
substance reasonably satisfactory to the holder of this Warrant), or the Company
shall make appropriate provision without the issuance of a new Warrant, so that
the holder of this Warrant shall have the right to receive, at a total purchase
price not to exceed that payable upon the exercise of the unexercised portion of
this Warrant, and in lieu of the shares of Common Stock theretofore issuable
upon exercise of this Warrant, (i) the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change,
merger or sale by a holder of the number of shares of Common Stock then
purchasable under this Warrant, or (ii) in the case of such a merger or sale in
which the consideration paid consists all or in part of assets other than
securities of the successor or purchasing corporation, at the option of the
Holder of this Warrant, the securities of the successor or purchasing
corporation having a value at the time of the transaction equivalent to the fair
market value of the Common Stock at the time of the transaction. The provisions
of this subparagraph (a) shall similarly apply to successive reclassifications,
changes, mergers and transfers.

<PAGE>

            (b) Stock Splits, Dividends and Combinations. In the event that the
Company shall at any time subdivide the outstanding shares of Common Stock or
shall issue a stock dividend on its outstanding shares of Common Stock the
number of Shares issuable upon exercise of this Warrant immediately prior to
such subdivision or to the issuance of such stock dividend shall be
proportionately increased, and the Exercise Price shall be proportionately
decreased, and in the event that the Company shall at any time combine the
outstanding shares of Common Stock the number of Shares issuable upon exercise
of this Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased, effective
at the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

      5. Notice of Adjustments. Whenever the number of Shares purchasable
hereunder or the Exercise Price thereof shall be adjusted pursuant to Section 3
hereof, the Company shall provide notice to the Holder setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated, and the number
and class of shares which may be purchased thereafter and the Exercise Price
therefor after giving effect to such adjustment.

      6. Representations of the Company. The Company represents that all
corporate actions on the part of the Company, its officers, directors and
shareholders necessary for the sale and issuance of the Shares pursuant hereto
and the performance of the Company's obligations hereunder were taken prior to
and are effective as of the effective date of this Warrant.

      7. Representations and Warranties by the Holder. The Holder represents and
warrants to the Company as follows:

            (a) This Warrant and the Shares issuable upon exercise thereof are
being acquired for its own account, for investment and not with a view to, or
for resale in connection with, any distribution or public offering thereof
within the meaning of the Securities Act of 1933, as amended (the "Act"). Upon
exercise of this Warrant, the Holder shall, if so requested by the Company,
confirm in writing, in a form satisfactory to the Company, that the securities
issuable upon exercise of this Warrant are being acquired for investment and not
with a view toward distribution or resale.

            (b) The Holder understands that the Warrant and the Shares have not
been registered under the Act by reason of their issuance in a transaction
exempt from the registration and prospectus delivery requirements of the Act
pursuant to Section 4(2) thereof, and that they must be held by the Holder
indefinitely, and that the Holder must therefore bear the economic risk of such
investment indefinitely, unless a subsequent disposition thereof is registered
under the Act or is exempted from such registration.

            (c) The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

            (d) The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

      7. Restrictive Legend.

            The Shares (unless registered under the Act) shall be stamped or
imprinted with a legend in substantially the following form:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND
NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF, AND
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUCH
SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT
STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT.

<PAGE>

     8. Transfer of Warrants. Notwithstanding anything to the contrary herein,
nothing shall prevent Holder from transferring the Warrant if the disposition
thereof is exempt from registration under the Act.

     9. Rights of Shareholders. No holder of this Warrant shall be entitled, as
a Warrant holder, to vote or receive dividends or be deemed the holder of any
Shares or any other securities of the Company which may at any time be issuable
on the exercise hereof for any purpose, nor shall anything contained herein be
construed to confer upon the holder of this Warrant, as such, any of the rights
of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to shareholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, consolidation, merger, conveyance, or otherwise) or to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until the
Warrant shall have been exercised and the Shares purchasable upon the exercise
hereof shall have become deliverable, as provided herein. The holder of this
Warrant will not be entitled to share in the assets of the Company in the event
of a liquidation, dissolution or the winding up of the Company.

     10. Notices. All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made and
sent when delivered, or mailed by registered or certified mail, return receipt
requested:

            (a) If to a Holder, to the address of such Holder as shown on the
books of the Company; or

            (b) If to the Company, to the address set forth herein or to such
other address as the Company may designate by notice to the Holders.

      11. Governing Law. This Warrant and all actions arising out of or in
connection with this Agreement shall be governed by and construed in accordance
with the laws of the State of Washington, without regard to the conflicts of law
provisions of the State of Washington or of any other state.
