                             STOCK OPTION AGREEMENT
                                       OF
                            RIM SEMICONDUCTOR COMPANY

         STOCK OPTION AGREEMENT (this "Agreement") entered into as of the 16th
day of February 2006, between RIM SEMICONDUCTOR COMPANY, a Utah corporation (the
"Corporation"), and DAVIS MUNCK BUTRUS, P.C., a Texas professional corporation
(the "Optionee").

         The Board of Directors of the Corporation approved the issuance to the
Optionee, effective as of the date set forth above, of a nonqualified stock
option to purchase up to an aggregate of 2,000,000 shares of the common stock,
par value $.001 per share, of the Corporation (the "Common Stock"), at an
exercise price of $ 0.0319 per share (the "Option Price"), upon the terms and
conditions hereinafter set forth.

         NOW, THEREFORE, in consideration of the mutual premises and
undertakings hereinafter set forth, the parties hereto agree as follows:

         1. OPTION; OPTION PRICE. The Board of Directors hereby grants as of the
date of this Agreement to the Optionee the option (the "Option") to purchase,
subject to the terms and conditions of this Agreement 2,000,000 shares of the
Common Stock of the Corporation at an exercise price per share equal to the
Option Price.

         2. TERM. The term (the "Option Term") of the Option shall commence on
the date of this Agreement and shall terminate on February 16, 2016.

         3. VESTING.

         (a) Subject to the provisions of Sections 5 and 8 hereof, on each
Measurement Date set forth in Column 1 below, the Option shall vest and become
exercisable for the corresponding number of shares of Common Stock set forth in
Column 2 below if the Option has not earlier terminated as provided in Section 4
hereof.

           Measurement Date                           Date

            March 1, 2006                          2,000,000
--------------------------------------- ---------------------------------

         (b) Notwithstanding the provisions of Section 3(a) hereof, the Option
shall become fully vested and shall become immediately exercisable with respect
to all shares subject to the Option, subject to the provisions hereof,
immediately following a Change of Control (as hereinafter defined) of the
Corporation. For purposes of this Agreement and the Option, a "Change of
Control" shall have occurred if (i) the Corporation is merged or consolidated or
reorganized into or with another corporation, and as result of such merger,
consolidation, or reorganization less than a majority of the combined voting
power of the then-outstanding securities of such corporation or entity
immediately after such transaction is held in the aggregate by the holders of
Voting Stock (as hereafter defined) of the Corporation immediately prior to such
transaction; (ii) the Corporation sells or otherwise transfers all or
substantially all of its assets to any other corporation or legal person, less
than a majority of the combined voting power of the then-outstanding securities
of such corporation or legal person immediately after such sale or transfer is

<PAGE>

held in the aggregate by the holders of the Voting Stock of the Corporation
immediately prior to such sale or transfer, (iii) if during any period of
twenty-four (24) months following a merger, tender offer, consolidation, sale of
assets, or contested election, at least a majority of the Board of Directors of
the Corporation shall cease to be "Continuing Directors." For purposes of this
Section 3(b), "Continuing Directors" shall mean directors of the Corporation
prior to such transaction or who subsequently became directors and whose
election or nomination for election by the stockholders of the Corporation was
approved by a vote of at least two-thirds (2/3) of the directors then still in
office prior to such transaction. The term "Voting Stock" shall mean, for
purposes of this Section 3(b), the then-outstanding securities entitled to vote
generally in the election of directors of the Corporation.

         (c) Subject to the provisions of Sections 5 and 8 hereof, the shares as
to which the Option is exercisable may be purchased at any time prior to the
expiration or termination of the Option.

         4. [RESERVED].

         5. PROCEDURE FOR EXERCISE.

         (a) Subject to the requirements of Section 8, the Option may be
exercised, from time to time, in whole or in part (but for the purchase of a
whole number of shares only), by delivery of a written notice (the "Notice")
from the Optionee to the Secretary of the Corporation, which Notice shall:

                  (i) state that the Optionee elects to exercise the Option;

                  (ii) state the number of shares with respect to which the
         Option is being exercised (the "Optioned Shares");

                  (iii) state the date upon which the Optionee desires to
         consummate the purchase of the Optioned Shares (which date must be
         prior to the termination of such Option and no later than thirty (30)
         days after the date of receipt of such Notice);

                  (iv) include any representations of the Optionee required
         under Section 8(c); and

                  (v) if the Option shall be exercised pursuant to Section 10 by
         any person other than the Optionee, include evidence to the
         satisfaction of the Board of Directors of the right of such person to
         exercise the Option.

         (b) Payment of the Option Price for the Optioned Shares shall be made
(i) in U.S. dollars by personal or company check, bank draft or money order
payable to the order of the Corporation or by wire transfer, or (ii) by delivery
of such other consideration as the Board of Directors may deem acceptable.

                                       2
<PAGE>


         (c) The Corporation shall issue a stock certificate in the name of the
Optionee (or such other person exercising the Option in accordance with the
provisions of Section 10) for the Optioned Shares as soon as practicable after
receipt of the Notice and payment of the aggregate Option Price for such shares.

         6. NO RIGHTS AS A STOCKHOLDER. The Optionee shall have no rights as a
stockholder of the Corporation with respect to any Optioned Shares until the
date the Optionee or, if Optionee is a natural person, his nominee (which, for
purposes of this Agreement, shall include any third party agent selected by the
Board of Directors to hold such Optioned Shares on behalf of the Optionee),
guardian or legal representative is the holder of record of such Optioned
Shares.

         7. ADJUSTMENTS.

         (a) If at any time while the Option is outstanding, there shall be any
increase or decrease in the number of issued and outstanding shares of Common
Stock through the declaration of a stock dividend, stock split, combination of
shares or through any recapitalization resulting in a stock split-up, spin-off,
combination or exchange of shares of Common Stock, then and in each such event
appropriate adjustment shall be made in the number of shares and the exercise
price per share covered by the Option, so that the same proportion of the
Corporation's issued and outstanding shares of Common Stock shall remain subject
to purchase at the same aggregate exercise price.

         (b) Except as otherwise expressly provided herein, the issuance by the
Corporation of shares of its capital stock of any class, or securities
convertible into shares of capital stock of any class, either in connection with
a direct sale or upon the exercise of rights or warrants to subscribe therefor,
or upon conversion of shares or obligations of the Corporation convertible into
such shares or other securities, shall not affect, and no adjustment by reason
thereof shall be made with respect to, the number of or exercise price of shares
of Common Stock covered by the Option.

         (c) Without limiting the generality of the foregoing, the existence of
the Option shall not affect in any manner the right or power of the Corporation
to make, authorize or consummate (i) any or all adjustments, recapitalizations,
reorganizations or other changes in the Corporation's capital structure or its
business; (ii) any merger or consolidation of the Corporation; (iii) any issue
by the Corporation of debt securities, or preferred or preference stock that
would rank above the shares of Common Stock covered by the Option; (iv) the
dissolution or liquidation of the Corporation; (v) any sale, transfer or
assignment of all or any part of the assets or business of the Corporation; or
(vi) any other corporate act or proceeding, whether of a similar character or
otherwise.

         (d) If the Corporation shall consummate any merger, consolidation,
business combination or other reorganization in which holders of shares of
Common Stock are entitled to receive in respect of such shares any securities,
cash and/or other consideration (including a different number of shares of
Common Stock) (collectively, a "Reorganization"), this Option shall thereafter
be exercisable, in accordance with this Agreement, only for the kind and amount
of securities, cash and/or other consideration receivable upon such
Reorganization by a holder of the same number of shares of Common Stock as are
subject to this Option immediately prior to such Reorganization, and any
adjustments will be made to the terms of this Option, and this Agreement, in the
sole discretion of the Corporation as it may deem appropriate to give effect to
the Reorganization.

         8. ADDITIONAL PROVISIONS RELATED TO EXERCISE.

         (a) The Option shall be exercisable only in accordance with this
Agreement, including the provisions regarding the period when the Option may be
exercised and the number of shares of Common Stock that may be acquired upon
exercise.

         (b) The Option may not be exercised as to less than one hundred (100)
shares of Common Stock at any one time unless less than one hundred (100) shares
of Common Stock remain to be purchased upon the exercise of the Option.

         (c) To exercise the Option, the Optionee shall follow the provisions of
Section 5 hereof. Upon the exercise of the Option at a time when there is not in
effect a registration statement under the Securities Act of 1933, as amended
(the "Securities Act") relating to the shares of Common Stock issuable upon
exercise of the Option, the Board of Directors in its discretion may, as a
condition to the exercise of the Option, require the Optionee (i) to represent
in writing that the shares of Common Stock received upon exercise of the Option
are being acquired for investment and not with a view to distribution and (ii)
to make such other representations and warranties as are deemed appropriate by
counsel to the Corporation or any underwriters or prospective underwriters
(including lock-up options). No Option may be exercised and no shares of Common
Stock shall be issued and delivered upon the exercise of the Option unless and
until the Corporation and/or the Optionee shall have complied with all
applicable federal or state registration, listing and/or qualification
requirements and all other requirements of law or of any regulatory agencies
having jurisdiction.

         (d) Stock certificates representing shares of Common Stock acquired
upon the exercise of the Option that have not been registered under the
Securities Act shall, if required by the Board of Directors, bear the following
legend:

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                  "ACT"). THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
                  HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
                  STATEMENT AS TO THE SECURITIES UNDER THE ACT OR PURSUANT TO AN
                  EXEMPTION FROM REGISTRATION OR AN OPINION OF COUNSEL
                  SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT
                  REQUIRED."

         (e) The exercise of each Option and the issuance of shares in
connection with the exercise of an Option shall, in all cases, be subject to the
satisfaction of withholding tax or other withholding liabilities.

         9. RESTRICTION ON TRANSFER. The Option may not be assigned or
transferred (which shall be deemed to include with respect to an Optionee that
is an entity a reorganization or merger or consolidation with any other person,
entity or corporation) except, if Optionee is a natural person, by will or by
the laws of descent and distribution or pursuant to a qualified domestic


                                       4
<PAGE>

relations order as defined in the Code, and may be exercised during the lifetime
or existence of the Optionee, as applicable, only by the Optionee or, if
Optionee is a natural person, the Optionee's guardian or legal representative or
assignee pursuant to a qualified domestic relations order. If the Optionee (who
is a natural person) dies, the Option shall thereafter be exercisable, during
the period specified in Section 4(a), by his executors or administrators or by a
person who acquired the right to exercise the Option by bequest or inheritance
to the full extent to which the Option was exercisable by the Optionee at the
time of his death. The Option shall not be subject to execution, attachment or
similar process. Any attempted assignment or transfer of the Option contrary to
the provisions hereof, and the levy of any execution, attachment or similar
process upon the Option, shall be null and void and without effect.
