                             (SUBJECT TO ADJUSTMENT)

                         (Void after December ___, 2008)

PPW -

         THIS COMMON STOCK PURCHASE WARRANT CERTIFIES that, for value received,
_____________ (the "Holder"), is entitled, upon the terms and subject to the
limitations on exercise and the conditions hereinafter set forth, at any time on
or after December ___, 2003 (the "Initial Exercise Date") and on or prior to the
close of business on December ___, 2008 (the "Termination Date") but not
thereafter, to subscribe for and purchase from DynTek, Inc., a Delaware
corporation (the "Company"), up to ____________ [30% OF SHARES OF COMMON STOCK
SO PURCHASED] shares (the "Warrant Shares") of Class A Common Stock, $.0001 par
value per share, of the Company (the "Common Stock"). The purchase price of one
share of Common Stock (the "Exercise Price") under this Warrant shall be $0.75,
subject to adjustment hereunder. The Exercise Price and the number of Warrant
Shares for which the Warrant is exercisable shall be subject to adjustment as
provided herein. Capitalized terms used and not otherwise defined herein shall
have the meanings set forth in that certain Securities Purchase Agreement dated
December 5, 2003, between the Company and the purchasers set forth on Schedule 1
thereto (the "Purchase Agreement").

         1. Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws and Section 7 of this Warrant, this Warrant and
all rights hereunder are transferable, in whole or in part, at the office or
agency of the Company by the Holder in person or by duly authorized attorney,
upon surrender of this Warrant together with the Assignment Form annexed hereto
properly endorsed. The transferee shall sign an investment letter in form and
substance reasonably satisfactory to the Company.

         2. Authorization of Shares. The Company covenants that all Warrant
Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this
Warrant, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges in respect of the issue thereof (other
than taxes in respect of any transfer occurring contemporaneously with such
issue).

         3. Exercise of Warrant.

            (a) Exercise of the purchase rights represented by this Warrant may
be made at any time or times on or after the Initial Exercise Date and on or
before the Termination Date by the surrender of this Warrant and the Notice of
Exercise Form annexed hereto duly executed, at the office of the Company (or
such other office or agency of the Company as it may designate by notice in
writing to the registered Holder at the address of such Holder appearing on the
books of the Company), and upon payment of the Exercise Price of the Warrant
Shares thereby purchased by wire transfer or cashier's check drawn on a United
States bank or by means of a cashless exercise pursuant to Section 3(d), the
Holder shall be entitled to receive a certificate for the number of Warrant
Shares so purchased. Certificates for Warrant Shares purchased hereunder shall
be delivered to the Holder within five (5) Trading Days after the date on which
this Warrant shall have been exercised as aforesaid. This Warrant shall be
deemed to have been exercised and such certificate or certificates shall be
deemed to have been issued, and the Holder or any other person so designated to
be named therein shall be deemed to have become a holder of record of such
shares for all purposes, as of the date the Warrant has been properly exercised
by payment to the Company of the Exercise Price and all taxes required to be
paid by the Holder, if any, pursuant to Section 5 have been paid. If such
conditions by the Holder have been met, and the Company fails to deliver to the
Holder a certificate or certificates representing the Warrant Shares pursuant to
this Section 3(a) by the close of business on the 5th Trading Day after the date
of such conditions being met by the Holder, then the Holder will have the right
to rescind such exercise. In addition to any other rights available to the
Holder, if the Company fails to deliver to the Holder a certificate or
certificates representing the Warrant Shares pursuant to a proper exercise, and
all conditions being met by the Holder, by the close of business on the 8th
Trading Day after the date of exercise, and if after such 8th Trading Day the
Holder is required by its broker to purchase (in an open market transaction or
otherwise) shares of Common Stock to deliver in satisfaction of a sale by the
Holder of the Warrant Shares which the Holder anticipated receiving upon such
exercise (a "Buy-In"), then the Company shall (1) pay in immediately available
funds to the Holder the amount by which (x) the Holder's total purchase price
(including brokerage commissions, if any) for the Warrant Shares so purchased
exceeds (y) the amount obtained by multiplying (A) the number of Warrant Shares
that the Company was required to deliver to the Holder in connection with the
exercise at issue times (B) the price at which the sell order giving rise to
such purchase obligation was executed, and (2) at the option of the Holder,
either reinstate the portion of the Warrant and equivalent number of Warrant
Shares for which such exercise was not honored or deliver to the Holder the
number of shares of Common Stock that would have been issued had the Company
timely complied with its exercise and delivery obligations hereunder. For
example, if the Holder purchases Common Stock having a total purchase price of
$100 to cover a Buy-In with respect to an attempted exercise of Warrant Shares
with an aggregate sale price giving rise to such purchase obligation of $80,
under clause (1) of the immediately preceding sentence the Company shall be
required to pay the Holder $20. The Holder shall provide the Company written
notice indicating the amounts payable to the Holder in respect of the Buy-In,
together with applicable confirmations and other evidence reasonably requested
by the Company. Nothing herein shall limit a Holder's right to pursue any other
remedies available to it hereunder, at law or in equity including, without
limitation, a decree of specific performance and/or injunctive relief with
respect to the Company's failure to timely deliver certificates representing
Warrant Shares as required pursuant to the terms hereof.

            (b) If this Warrant shall have been exercised in part, the Company
shall, at the time of delivery of the certificate or certificates representing
Warrant Shares, deliver to Holder a new Warrant evidencing the rights of Holder
to purchase the unpurchased Warrant Shares called for by this Warrant, which new
Warrant shall in all other respects be identical with this Warrant.

            (c) The Company shall not effect any exercise of this Warrant, and
the Holder shall not have the right to exercise any portion of this Warrant,
pursuant to Section 3(a) or otherwise, to the extent that after giving effect to
such issuance after exercise, the Holder (together with the Holder's
Affiliates), as set forth on the applicable Notice of Exercise, would
beneficially own in excess of 5% of the number of shares of the Common Stock
issued and outstanding immediately after giving effect to such issuance. For
purposes of the foregoing sentence, the number of shares of Common Stock
beneficially owned by the Holder and its Affiliates shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to
which the determination of such sentence is being made, but shall exclude the
number of shares of Common Stock which would be issuable upon (A) exercise of
the remaining, nonexercised portion of this Warrant beneficially owned by the
Holder or any of its Affiliates and (B) exercise or conversion of the
unexercised or nonconverted portion of any other securities of the Company
(including, without limitation, any other Warrants) subject to a limitation on
conversion or exercise analogous to the limitation contained herein beneficially
owned by the Holder or any of its Affiliates. Except as set forth in the
preceding sentence, for purposes of this Section 3(c), beneficial ownership
shall be calculated in accordance with Section 13(d) of the Exchange Act. For
purposes of this Section 3(c), in determining the number of outstanding shares
of Common Stock, the Holder may rely on the number of outstanding shares of
Common Stock as reflected in (x) the Company's most recent Form 10-Q or Form
10-K, as the case may be, (y) a more recent public announcement by the Company
or (z) any other notice by the Company or the Company's transfer agent setting
forth the number of shares of Common Stock outstanding. Upon the written or oral
request of the Holder, the Company shall within two Trading Days confirm orally
and in writing to the Holder the number of shares of Common Stock then
outstanding. In any case, the number of outstanding shares of Company Common
Stock shall be determined after giving effect to the conversion or exercise of
securities of the Company, including this Warrant, by the Holder or its
Affiliates since the date as of which such number of outstanding shares of
Common Stock was reported. The provisions of this Section 3(c) may be waived by
the Holder upon, at the election of the Holder, not less than 61 days' prior
notice to the Company, and the provisions of this Section 3(c) shall continue to
apply until such 61st day (or such later date, as determined by the Holder, as
may be specified in such notice of waiver). The Holder is solely responsible for
all calculations required in this Section 3(c). The Company shall have no
liability for any issuances of Warrant Shares that exceed the 5% amount and the
Company is entitled to rely on all calculations by the Holder and/or its agents.
The Holder's exercise notice shall be deemed a representation of the Holder that
the number of Warrant Shares to be acquired pursuant to such exercise notice
shall be in compliance with the provisions of this Section 3(c).

                                      -4-

            (d) If, but only if, at any time after one year from the date of
issuance of this Warrant there is no effective Registration Statement
registering the resale of the Warrant Shares by the Holder, this Warrant may
also be exercised at such time by means of a "cashless exercise" in which the
Holder shall be entitled to receive a certificate for the number of Warrant
Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

         (A) = the Closing Price on the Trading Day preceding the date of such
election;

         (B) = the Exercise Price of the Warrants, as adjusted; and

         (X) = the number of Warrant Shares issuable upon exercise of the
               Warrants in accordance with the terms of this Warrant.

         4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price.

         5. Charges, Taxes and Expenses. Issuance of certificates for Warrant
Shares shall be made without charge to the Holder for any issue or transfer tax
or other incidental expense in respect of the issuance of such certificate, all
of which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be
directed by the Holder; provided, however, that in the event certificates for
Warrant Shares are to be issued in a name other than the name of the Holder,
this Warrant when surrendered for exercise shall be accompanied by the
Assignment Form attached hereto duly executed by the Holder; and the Company may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

         6. Closing of Books. The Company will not close its stockholder books
or records in any manner which prevents the timely exercise of this Warrant,
pursuant to the terms hereof.

         7. Transfer, Division and Combination.

            (a) Subject to compliance with any applicable securities laws and
the conditions set forth in Section 1 and Section 7(e) hereof and to the
provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights
hereunder are transferable, in whole or in part, upon surrender of this Warrant
at the principal office of the Company, together with a written assignment of
this Warrant substantially in the form attached hereto duly executed by the
Holder or its agent or attorney and funds sufficient to pay any transfer taxes
payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in
the name of the assignee or assignees and in the denomination or denominations
specified in such instrument of assignment, and shall issue to the assignor a
new Warrant evidencing the portion of this Warrant not so assigned, and this
Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be
exercised by a new holder for the purchase of Warrant Shares without having a
new Warrant issued.

                                      -5-

            (b) This Warrant may be divided or combined with other Warrants upon
presentation hereof at the aforesaid office of the Company, together with a
written notice specifying the names and denominations in which new Warrants are
to be issued, signed by the Holder or its agent or attorney. Subject to
compliance with Section 7(a), as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or
Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice.

            (c) The Company shall prepare, issue and deliver at its own expense
(other than transfer taxes) the new Warrant or Warrants under this Section 7.

            (d) The Company agrees to maintain, at its aforesaid office, books
for the registration and the registration of transfer of the Warrants.

            (e) If, at the time of the surrender of this Warrant in connection
with any transfer of this Warrant, the transfer of this Warrant shall not be
registered pursuant to an effective registration statement under the Securities
Act and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such transfer (i) that the Holder or
transferee of this Warrant, as the case may be, furnish to the Company a written
opinion of counsel (which opinion shall be in form, substance and scope
customary for opinions of counsel in comparable transactions) to the effect that
such transfer may be made without registration under the Securities Act and
under applicable state securities or blue sky laws, (ii) that the holder or
transferee execute and deliver to the Company an investment letter in form and
substance acceptable to the Company and (iii) that the transferee be an
"accredited investor" as defined in Rule 501(a) promulgated under the Securities
Act.

         8. No Rights as Shareholder Until Exercise. This Warrant does not
entitle the Holder to any voting rights or other rights as a shareholder of the
Company prior to the exercise hereof. Upon the surrender of this Warrant and the
payment of the aggregate Exercise Price (or by means of a cashless exercise),
the Warrant Shares so purchased shall be and be deemed to be issued to such
Holder as the record owner of such shares as of the close of business on the
later of the date of such surrender or payment.

         9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant or any stock
certificate relating to the Warrant Shares, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it (which, in
the case of the Warrant, shall not include the posting of any bond), and upon
surrender and cancellation of such Warrant or stock certificate, if mutilated,
the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock
certificate.

                                      -6-

         10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for
the taking of any action or the expiration of any right required or granted
herein shall be a Saturday, Sunday or a legal holiday in the State of New York,
then such action may be taken or such right may be exercised on the next
succeeding day not a Saturday, Sunday or legal holiday in the State of New York.

         11. Adjustments to Exercise Price and Number of Warrant Shares.

         For purposes of this Section 11, references to Common Stock shall also
include common stock equivalents (including but not limited to shares of Class B
Common Stock, par value $.0001 of the Company) ("Common Stock Equivalents");
provided, that Common Stock Equivalent shall not include any securities that are
defined in Section 11(b)(ii)(A) as Convertible Securities.

             (a) Stock Splits, Etc. The number and kind of securities
purchasable upon the exercise of this Warrant and the Exercise Price shall be
subject to adjustment from time to time upon the happening of any of the
following. In case the Company shall (i) pay a dividend in shares of Common
Stock or make a distribution in shares of Common Stock to holders of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock
into a greater number of shares, (iii) combine its outstanding shares of Common
Stock into a smaller number of shares of Common Stock, or (iv) issue any shares
of its capital stock in a reclassification of the Common Stock, then the number
of Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the Holder shall be entitled to receive the
kind and number of Warrant Shares or other securities of the Company which it
would have owned or have been entitled to receive had such Warrant been
exercised in advance thereof. Upon each such adjustment of the kind and number
of Warrant Shares or other securities of the Company which are purchasable
hereunder pursuant to this Section 11(a), the Holder shall thereafter be
entitled to purchase the number of Warrant Shares or other securities resulting
from such adjustment at an Exercise Price per Warrant Share or other security
obtained by multiplying the Exercise Price in effect immediately prior to such
adjustment by the number of Warrant Shares purchasable pursuant hereto
immediately prior to such adjustment and dividing by the number of Warrant
Shares or other securities of the Company resulting from such adjustment. An
adjustment made pursuant to this paragraph shall become effective immediately
after the effective date of such event retroactive to the record date, if any,
for such event.

             (b) Anti-Dilution Provisions. From the Initial Exercise Date until
one (1) year following the Closing Date, the Exercise Price and the number of
Warrant Shares issuable hereunder and for which this Warrant is then exercisable
pursuant to Section 1 hereof shall be subject to adjustment from time to time as
provided in this Section 11(b). In the event that any adjustment of the Exercise
Price as required herein results in a fraction of a cent, such Exercise Price
shall be rounded up or down to the nearest cent.
<PAGE>

                                      -7-

                 (i) Adjustment of Exercise Price. If and whenever the Company
issues or sells, or in accordance with this Section 11(b) hereof is deemed to
have issued or sold, any shares of Common Stock for a consideration per share
less than the then Exercise Price or for no consideration (such lower price, the
"Base Share Price" and such issuances collectively, a "Dilutive Issuance"),
then, the Exercise Price shall be reduced to equal the Base Share Price;
provided, that for purposes hereof, all shares of Common Stock that are issuable
upon conversion, exercise or exchange of Common Stock Equivalents shall be
deemed outstanding immediately after the issuance of such Common Stock
Equivalents. Such adjustment shall be made whenever such shares of Common Stock
or Common Stock Equivalents are issued.

                 (ii) Effect on Exercise Price of Certain Events. For purposes
of determining the adjusted Exercise Price under Section 11(b) hereof, the
following will be applicable:

                      (A) Issuance of Rights or Options. If the Company in any
manner issues or grants any warrants, rights or options, whether or not
immediately exercisable, to subscribe for or to purchase Common Stock or other
securities exercisable, convertible into or exchangeable for Common Stock
("Convertible Securities") (such warrants, rights and options to purchase Common
Stock or Convertible Securities are hereinafter referred to as "Options") and
the effective price per share for which Common Stock is issuable upon the
exercise of such Options is less than the Exercise Price ("Below Base Price
Options"), then the maximum total number of shares of Common Stock issuable upon
the exercise of all such Below Base Price Options (assuming full exercise,
conversion or exchange of Convertible Securities, if applicable) will, as of the
date of the issuance or grant of such Below Base Price Options, be deemed to be
outstanding and to have been issued and sold by the Company for such price per
share and the maximum consideration payable to the Company upon such exercise
(assuming full exercise, conversion or exchange of Convertible Securities, if
applicable) will be deemed to have been received by the Company. For purposes of
the preceding sentence, the "effective price per share for which Common Stock is
issuable upon the exercise of such Below Base Price Options" is determined by
dividing (i) the total amount, if any, received or receivable by the Company as
consideration for the issuance or granting of all such Below Base Price Options,
plus the minimum aggregate amount of additional consideration, if any, payable
to the Company upon the exercise of all such Below Base Price Options, plus, in
the case of Convertible Securities issuable upon the exercise or conversion of
such Below Base Price Options, the minimum aggregate amount of additional
consideration payable upon the exercise, conversion or exchange thereof at the
time such Convertible Securities first become exercisable, convertible or
exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the exercise of all such Below Base Price Options (assuming full
conversion of Convertible Securities, if applicable). No further adjustment to
the Exercise Price will be made upon the actual issuance of such Common Stock
upon the exercise of such Below Base Price Options or upon the exercise,
conversion or exchange of Convertible Securities issuable upon exercise of such
Below Base Price Options.

                      (B) Issuance of Convertible Securities. If the Company in
any manner issues or sells any Convertible Securities, whether or not
immediately convertible (other than where the same are issuable upon the
exercise of Options) and the effective price per share for which Common Stock is
issuable upon such exercise, conversion or exchange is less than the Exercise
Price, then the maximum total number of shares of Common Stock issuable upon the
exercise, conversion or exchange of all such Convertible Securities will, as of
the date of the issuance of such Convertible Securities, be deemed to be
outstanding and to have been issued and sold by the Company for such price per
share and the maximum consideration payable to the Company upon such exercise
(assuming full exercise, conversion or exchange of Convertible Securities, if
applicable) will be deemed to have been received by the Company. For the
purposes of the preceding sentence, the "effective price per share for which
Common Stock is issuable upon such exercise, conversion or exchange" is
determined by dividing (i) the total amount, if any, received or receivable by
the Company as consideration for the issuance or sale of all such Convertible
Securities, plus the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the exercise, conversion or exchange thereof at
the time such Convertible Securities first become exercisable, convertible or
exchangeable, by (ii) the maximum total number of shares of Common Stock
issuable upon the exercise, conversion or exchange of all such Convertible
Securities. No further adjustment to the Exercise Price will be made upon the
actual issuance of such Common Stock upon exercise, conversion or exchange of
such Convertible Securities.

                                      -8-

                      (C) Change in Option Price or Conversion Rate. If there is
a change at any time in (i) the amount of additional consideration payable to
the Company upon the exercise of any Options; (ii) the amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange of any Convertible Securities; or (iii) the rate at which any
Convertible Securities are convertible into or exchangeable for Common Stock (in
each such case, other than under or by reason of provisions designed to protect
against dilution), the Exercise Price in effect at the time of such change will
be readjusted to the Exercise Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for such
changed additional consideration or changed conversion rate, as the case may be,
at the time initially granted, issued or sold.

                      (D) Calculation of Consideration Received. If any Common
Stock, Options or Convertible Securities are issued, granted or sold for cash,
the consideration received therefor for purposes of this Warrant will be the
amount received by the Company therefor, before deduction of reasonable
commissions, underwriting allowances or other reasonable expenses paid or
incurred by the Company in connection with such issuance, grant or sale. In case
any Common Stock, Options or Convertible Securities are issued or sold for a
consideration part or all of which shall be other than cash, the amount of the
consideration other than cash received by the Company will be the fair market
value of such consideration, except where such consideration consists of
securities, in which case the amount of consideration received by the Company
will be the fair market value (closing bid price, if traded on any market)
thereof as of the date of receipt. In case any Common Stock, Options or
Convertible Securities are issued in connection with any merger or consolidation
in which the Company is the surviving corporation, the amount of consideration
therefor will be deemed to be the fair market value of such portion of the net
assets and business of the non-surviving corporation as is attributable to such
Common Stock, Options or Convertible Securities, as the case may be. The fair
market value of any consideration other than cash or securities will be
determined in good faith by an investment banker or other appropriate expert of
national reputation selected by the Company and reasonably acceptable to the
holder hereof, with the costs of such appraisal to be borne by the Company.

                      (E) Exceptions to Adjustment of Exercise Price.
Notwithstanding anything to the contrary herein, this Section 11(b) shall not
apply to the following (1) the granting of options to employees, officers,
directors or consultants of the Company pursuant to any stock option plan or
other written compensatory agreement duly adopted by a majority of the
non-employee members of the Board of Directors of the Company or a majority of
the members of a committee of non-employee directors established for such
purpose, or (2) the exercise of any security issued by the Company in connection
with the offer and sale of the Company's securities pursuant to the Purchase
Agreement (including any securities issued as compensation in connection
therewith), or (3) the exercise of or conversion of any convertible securities,
options or warrants issued and outstanding on the date hereof, provided such
securities have not been amended since the date hereof, or (4) the issuance of
securities in connection with acquisitions, joint ventures, arrangements related
to the Company's operations and strategic relationships, or other strategic
investments, the primary purpose of which is not to raise capital.

                 (iii) Minimum Adjustment of Exercise Price. No adjustment
of the Exercise Price shall be made in an amount of less than 1% of the Exercise
Price in effect at the time such adjustment is otherwise required to be made,
but any such lesser adjustment shall be carried forward and shall be made at the
time and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

         12. Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to any class of common stock of the
Company), or sell, transfer or otherwise dispose of all or substantially all its
property, assets or business to another corporation and, pursuant to the terms
of such reorganization, reclassification, merger, consolidation or disposition
of assets, shares of common stock of the successor or acquiring corporation, or
any cash, shares of stock or other securities or property of any nature
whatsoever (including warrants or other subscription or purchase rights) in
addition to or in lieu of common stock of the successor or acquiring corporation
("Other Property"), are to be received by or distributed to the holders of
Common Stock of the Company, then the Holder shall have the right thereafter to
receive, upon exercise of this Warrant, the number of shares of Common Stock of
the successor or acquiring corporation or of the Company, if it is the surviving
corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such event. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Company) shall expressly assume the
due and punctual observance and performance of each and every covenant and
condition of this Warrant to be performed and observed by the Company and all
the obligations and liabilities hereunder, subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of Warrant Shares
for which this Warrant is exercisable which shall be as nearly equivalent as
practicable to the adjustments provided for in this Section 12. For purposes of

include stock of such corporation of any class which is not preferred as to
dividends or assets over any other class of stock of such corporation and which
is not subject to redemption and shall also include any evidences of
indebtedness, shares of stock or other securities which are convertible into or
exchangeable for any such stock, either immediately or upon the arrival of a
specified date or the happening of a specified event and any warrants or other
rights to subscribe for or purchase any such stock. The foregoing provisions of
this Section 12 shall similarly apply to successive reorganizations,
reclassifications, mergers, consolidations or disposition of assets.

         13. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

         14. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted, as herein provided, the Company
shall give notice thereof to the Holder, which notice shall state the number of
Warrant Shares (and other securities or property) purchasable upon the exercise
of this Warrant and the Exercise Price of such Warrant Shares (and other
securities or property) after such adjustment, setting forth a brief statement
of the facts requiring such adjustment and setting forth the computation by
which such adjustment was made.

         15. Notice of Corporate Action. If at any time:

             (a) the Company shall take a record of the holders of its Common
Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

             (b) there shall be any capital reorganization of the Company, any
reclassification or recapitalization of the capital stock of the Company or any
consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation or,

             (c) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 10 days' prior written notice of the date on which a record date shall be
selected for such dividend, distribution or right or for determining rights to
vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 10
days' prior written notice of the date when the same shall take place. Such
notice in accordance with the foregoing clause also shall specify (i) the date
on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their Warrant Shares for securities or other property
deliverable upon such disposition, dissolution, liquidation or winding up. Each
such written notice shall be sufficiently given if addressed to Holder at the
last address of Holder appearing on the books of the Company and delivered in
accordance with Section 17(d).

             16. Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the principal Trading
Market upon which the Common Stock may be listed.

                 (a) Except and to the extent as waived or consented to by the
Holder, the Company shall not by any action, including, without limitation,
amending its certificate of incorporation or through any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, but will at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate to protect the rights of Holder
as set forth in this Warrant against impairment. Without limiting the generality
of the foregoing, the Company will (a) not increase the par value of any Warrant
Shares above the amount payable therefor upon such exercise immediately prior to
such increase in par value, (b) take all such action as may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use
commercially reasonable efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be
necessary to enable the Company to perform its obligations under this Warrant.

                 (b) Before taking any action which would result in an
adjustment in the number of Warrant Shares for which this Warrant is exercisable
or in the Exercise Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

         17. Miscellaneous.

             (a) Jurisdiction. This Agreement shall be governed by and construed
in accordance with the internal laws of the State of New York without regard to
the conflicts of laws principles thereof. The parties hereto hereby irrevocably
agree that any suit or proceeding arising directly and/or indirectly pursuant to
or under this Agreement, shall be brought solely in a federal or state court
located in the City, County and State of New York. By its execution hereof, the
parties hereby covenant and irrevocably submit to the in personam jurisdiction
of the federal and state courts located in the City, County and State of New
York and agree that any process in any such action may be served upon any of
them personally, or by certified mail or registered mail upon them or their
agent, return receipt requested, with the same full force and effect as if
personally served upon them in New York City. The parties hereto waive any claim
that any such jurisdiction is not a convenient forum for any such suit or
proceeding and any defense or lack of in personam jurisdiction with respect
thereto. In the event of any such action or proceeding, the party prevailing
therein shall be entitled to payment from the other party hereto of its
reasonable counsel fees and disbursements in an amount judicially determined.

             (b) Restrictions. The Holder acknowledges that the Warrant Shares
acquired upon the exercise of this Warrant, if not registered for resale under
the Securities Act, will have legends imprinted upon any stock certificates
evidencing such Warrant Shares and the Company will notify its transfer agent of
restrictions upon resale imposed by the applicable state and federal securities
laws.

             (c) Nonwaiver and Expenses. No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies,
notwithstanding all rights hereunder terminate on the Termination Date. If the
Company willfully and knowingly fails to comply with any provision of this
Warrant, which results in any material damages to the Holder, the Company shall
pay to Holder such amounts as shall be sufficient to cover any costs and
expenses including, but not limited to, reasonable attorneys' fees, including
those of appellate proceedings, incurred by Holder in collecting any amounts due
pursuant hereto or in otherwise enforcing any of its rights, powers or remedies
hereunder.

             (d) Notices. Any notice, request or other document required or
permitted to be given or delivered to the Holder by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement;
provided, upon any permitted assignment of this Warrant, the assignee shall
promptly provide the Company with its contact information.

             (e) Limitation of Liability. No provision hereof, in the absence of
any affirmative action by Holder to exercise this Warrant or purchase Warrant
Shares, and no enumeration herein of the rights or privileges of Holder, shall
give rise to any liability of Holder for the purchase price of any Common Stock
or as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

             (f) Remedies. Holder, in addition to being entitled to exercise all
rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Warrant. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Warrant and hereby agrees to
waive the defense in any action for specific performance that a remedy at law
would be adequate.

                                      -13-

             (g) Successors and Assigns. Subject to applicable securities laws,
this Warrant and the rights and obligations evidenced hereby shall inure to the
benefit of and be binding upon the successors of the Company and the successors
and permitted assigns of Holder. The provisions of this Warrant are intended to
be for the benefit of all Holders from time to time of this Warrant and shall be
enforceable by any such Holder or holder of Warrant Shares.

             (h) Amendment. This Warrant may be modified or amended or the
provisions hereof waived with the written consent of the Company and the Holder.

             (i) Severability. Wherever possible, each provision of this Warrant
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

             (j) Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

         18. Redemption of Warrants.

             (a) Commencing on the date following the final closing of the
private placement in which this Warrant was sold, on not less than ten (10)
days' written notice (the "Redemption Notice"), to the holder of this Warrant,
this Warrant may be redeemed, at the option of the Company, in whole and not in
part, at a redemption price of $1.75 (the "Redemption Price"), provided (i) the
"Market Price" of a share of Common Stock shall equal at least the Redemption
Price for the twenty (20) consecutive Trading Days ending on the Trading Day
immediately prior to the date of the Redemption Notice (the "Target Price"),
subject to adjustments as set forth in Section 11 hereof, (ii) the Company then
has sufficient authorized capital to permit issuance of the full number of
Warrant Shares upon exercise of the Warrant, (iii) the Warrant Shares are listed
or included for trading on a Trading Market and (iv) a registration statement
covering the Warrant Shares filed under the Securities Act of 1933, as amended
(the "Securities Act") has been declared effective by the Securities and
Exchange Commission and remains effective on the date fixed for redemption of
this Warrant (the "Redemption Date"). For purposes of this Warrant, Market Price
is defined as the closing bid price per share of Common Stock on the principal
Trading Market on which the Common Stock is included for trading; provided, that
if there is no trading in the Common Stock on a particular Trading Day on the
relevant principal Trading Market, the Market Price for that day shall be the
Market Price on the last preceding Trading Day on which there was trading in the
Common Stock on the principal Trading Market.
<PAGE>

                                      -14-

             (b) If the conditions set forth in Section 18 are met, and the
Company desires to exercise its right to redeem this Warrant, it shall mail a
Redemption Notice to the registered holder of this Warrant by first class mail,
postage prepaid, not later than the fifth (5th) day before the date fixed for
redemption, as provided in Section 18(a) hereof.

             (c) The Redemption Notice shall specify (i) the Redemption Price,
(ii) the Redemption Date, (iii) the place where the Warrant certificates shall
be delivered and the redemption price paid, and (iv) that the right to exercise
this Warrant shall terminate at 5:00 p.m. (New York time) on the business day
immediately preceding the Redemption Date. No failure to mail such notice nor
any defect therein or in the mailing thereof shall affect the validity of the
proceedings for such redemption except as to a holder (a) to whom notice was not
mailed, or (b) whose notice was defective. An affidavit of the Secretary or an
Assistant Secretary of the Company that the Redemption Notice has been mailed
shall, in the absence of fraud, be prima facie evidence of the facts stated
therein.

             (d) Any right to exercise a Warrant shall terminate at 5:00 p.m.
(New York time) on the business day immediately preceding the Redemption Date.
On and after the Redemption Date, the holder of this Warrant shall have no
further rights except to receive, upon surrender of this Warrant, the Redemption
Price.

             (e) From and after the Redemption Date, the Company shall, at the
place specified in the Redemption Notice, upon presentation and surrender to the
Company by or on behalf of the holder thereof the warrant certificates
evidencing this Warrant being redeemed, deliver, or cause to be delivered to or
upon the written order of such holder, a sum in cash equal to the Redemption
Price of this Warrant. From and after the Redemption Date, this Warrant shall
expire and become void and all rights hereunder and under the warrant
certificates, except the right to receive payment of the Redemption Price, shall
cease.

             (f) If the shares of Common Stock are subdivided or combined into a
greater or smaller number of shares of Common Stock, the Target Price shall be
proportionately adjusted by the ratio which the total number of shares of Common
Stock outstanding immediately prior to such event bears to the total number of
shares of Common Stock to be outstanding immediately after such event.

                          Dated as of December 9, 2003

================================================================================
<PAGE>

         PLACEMENT AGENT WARRANT AGREEMENT, dated as of December 9, 2003,
between DynTek, Inc., a Delaware corporation (the "Company"), and Rockwood Inc.
(hereinafter referred to variously as the "Holder" or "Rockwood").

                              W I T N E S S E T H:

         WHEREAS, Rockwood has acted pursuant to that certain Investment Banking
Advisory Agreement, dated November 19, 2003 ("Engagement Agreement"), by and
between the Company and Duncan Capital LLC ("Duncan Capital"), an affiliate of
Rockwood, as exclusive placement agent to effect a private offering of
approximately $2,200,000 in securities (the "Offering"); and

         WHEREAS, the Company proposes to issue to Rockwood or its designee(s)
warrants (the "Warrants") to purchase up to 500,000 shares of Class A Common
Stock, $0.0001 par value per share, of the Company ("Common Stock");

         WHEREAS, Rockwood Capital has requested that all of the Warrants be
issued in the name of Duncan Capital;

         WHEREAS, the Warrants to be issued pursuant to this Agreement will be
issued at the Closing (as such term is defined in the Securities Purchase
Agreement) by the Company to Rockwood, or its designee, in consideration for,
and as part of Rockwood's compensation in connection with, Rockwood acting as
exclusive placement agent pursuant to the Engagement Agreement;

         NOW, THEREFORE, in consideration of the premises made herein, the
payment by Rockwood to the Company of $50.00, the agreements herein set forth,
and other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereto agree as follows:

                                       2
<PAGE>

         1. Grant. The Holder (as defined in Section 3 hereof) is hereby granted
the right to purchase, at any time from December 9, 2003, (the "Initial Exercise
Date") until 5:30 P.M., New York time, on December 9, 2008, up to 500,000 shares
of Common Stock at an initial exercise price (subject to adjustment as provided
in Article 8 hereof) of $0.913 per share of Common Stock, subject to the terms
and conditions of this Agreement.

         2. Warrant Certificates. The warrant certificates (the "Warrant
Certificates") delivered and to be delivered pursuant to this Agreement shall be
in the form set forth in Exhibit A attached hereto and made a part hereof, with
such appropriate insertions, omissions, substitutions, and other variations as
required or permitted by this Agreement.

         3. Exercise of Warrant.

         3.1 Method of Exercise. The Warrants initially are exercisable at an
initial exercise price (subject to adjustment as provided in Section 8 hereof)
per share of Common Stock set forth in Section 6 hereof, payable by certified or
official bank check in New York Clearing House funds. Upon surrender of a
Warrant Certificate with the annexed Form of Election to Purchase duly executed,
together with payment of the Purchase Price (as hereinafter defined) for the
shares of Common Stock purchased at the Company's principal offices (presently
located at 18881 Von Karman Avenue, Suite 250, Irvine, CA 92612) the registered
holder of a Warrant Certificate ("Holder" or "Holders") shall be entitled to
receive a certificate or certificates for the shares of Common Stock so
purchased. The purchase rights represented by each Warrant Certificate are
exercisable at the option of the Holder thereof, in whole or in part (but not as
to fractional shares of the Common Stock underlying the Warrants). Warrants may
be exercised to purchase all or part of the shares of Common Stock represented
thereby. In the case of the purchase of less than all the shares of Common Stock
purchasable under any Warrant Certificate, the Company shall cancel said Warrant
Certificate upon the surrender thereof and shall execute and deliver a new
Warrant Certificate of like tenor for the balance of the shares of Common Stock
purchasable thereunder.

                                       2
<PAGE>

         3.2 Exercise by Surrender of Warrant. In addition to the method of
payment set forth in Section 3.1 and in lieu of any cash payment required
thereunder, the Holder(s) of the Warrants shall have the right at any time and
from time to time to exercise the Warrants in whole or in part by surrendering
the Warrant Certificate in the manner specified in Section 3.1 hereof in
exchange for that number of shares of Common Stock equal to the product of (x)
the number of shares as to which such Warrants are being exercised multiplied by
(y) a fraction, the numerator of which is the Market Price (as hereinafter
defined) of the Common Stock less the Exercise Price and the denominator of
which is such Market Price. Solely for the purposes of this Section 3.2, Market
Price shall be calculated either (i) on the date on which the Form of Election
to Purchase annexed to such Warrant Certificate as to such exercise is deemed to
have been sent to the Company pursuant to Section 14 hereof (the "Notice Date")
or (ii) as the average of the Market Prices for each of the five trading days
preceding the Notice Date, whichever results in a higher Market Price.

         3.3 Definition of Market Price. As used herein, the phrase "Market
Price" at any date shall be deemed to be the last reported sale price, or, in
case no such reported sale takes place on such day, the average of the last
reported sale prices for the last three (3) trading days, in either case as
officially reported by the principal securities exchange on which the Common
Stock is listed or admitted to trading, or if the Common Stock is not listed or
admitted to trading on any national securities exchange, the average closing bid
price as furnished by the NASD through NASDAQ or similar organization if NASDAQ
is no longer reporting such information, or if the Common Stock is not quoted on
NASDAQ, as determined in good faith by resolution of the Board of Directors of
the Company, based on the best information available to it.

                                       3
<PAGE>

         4. Issuance of Certificates. Upon the exercise of the Warrants, the
issuance of certificates for shares of Common Stock or other securities,
properties or rights underlying such Warrants, shall be made forthwith (and in
any event within three (3) business days thereafter) without charge to the
Holder thereof including, without limitation, any tax which may be payable in
respect of the issuance thereof, and such certificates shall (subject to the
provisions of Sections 5 and 7 hereof) be issued in the name of, or in such
names as may be directed by, the Holder thereof; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any such certificates in a
name other than that of the Holder and the Company shall not be required to
issue or deliver such certificates unless or until the person or persons
requesting the issuance thereof shall have paid to the Company the amount of
such tax or shall have established to the satisfaction of the Company that such
tax has been paid.

         The Warrant Certificates and the certificates representing the shares
of Common Stock (and/or other securities, property or rights issuable upon the
exercise of the Warrants) shall be executed on behalf of the Company by the
manual or facsimile signature of the then present Chairman or Vice Chairman of
the Board of Directors or President or Vice President of the Company under its
corporate seal reproduced thereon, attested to by the manual or facsimile
signature of the then present Secretary or Assistant Secretary of the Company.
Warrant Certificates shall be dated the date of execution by the Company upon
initial issuance, division, exchange, substitution or transfer.

                                       4
<PAGE>

         5. Restriction on Transfer of Warrants. The Holder of a Warrant
Certificate, by its acceptance thereof, covenants and agrees that the Warrants
described therein are being acquired as an investment and not with a view to the
distribution thereof.

         6. Exercise Price.

         6.1 Initial and Adjusted Exercise Price. Except as otherwise provided
in Section 8 hereof, the initial exercise price of each Warrant shall be $0.913
per share of Common Stock. The adjusted exercise price of each Warrant shall be
the price which shall result from time to time from any and all adjustments of
the initial exercise price in accordance with the provisions of Section 8
hereof.

         6.2 Exercise Price. The term "Exercise Price" herein shall mean the
initial exercise price or the adjusted exercise price, depending upon the

         7. Registration Rights.

         7.1 Registration Under the Securities Act of 1933. The Warrants and the
shares of Common Stock issuable upon exercise of the Warrants or other
securities issuable upon exercise of the Warrants, have not been registered
under the Securities Act of 1933, as amended (the "Act"). Upon exercise, in part
or in whole, of the Warrant certificates representing the shares of Common Stock
underlying the Warrants, certificates representing the shares of Common Stock
and any other securities issuable upon exercise of the Warrants (collectively,
the "Warrant Securities") shall bear the following legend:

                                       5
<PAGE>

         The securities represented by this certificate have not been registered
         under the Securities Act of 1933, as amended ("Act"), and may not be
         offered or sold except pursuant to (i) an effective registration
         statement under the Act, (ii) to the extent applicable, Rule 144 under
         the Act (or any similar rule under such Act relating to the disposition
         of securities), or (iii) an opinion of counsel, if such opinion shall
         be reasonably satisfactory to counsel to the issuer, that an exemption
         from registration under such Act is available.

         7.2 Piggyback Registration. If, at any time during the seven-year
period commencing on the date the Warrants are issued, the Company proposes to
register any of its securities under the Act (other than pursuant to Form S-8,
S-4 or a comparable registration statement) the Company will give written notice
by registered mail, at least thirty (30) days prior to the filing of each such
registration statement, to the Placement Agent and to all other Holders of the
Warrant Securities of its intention to do so. If the Placement Agent or other
Holders of the Warrant Securities notify the Company within twenty (20) days
after receipt of any such notice of its or their desire to include any such
securities in such proposed registration statement, the Company shall afford the
Placement Agent and such Holders of the Warrant Securities the opportunity to
have any such Warrant Securities registered under such registration statement;
provided, however, that it is understood and agreed that the Company shall
register all of the Warrant Securities as part of the registration statement it
is obligated to file pursuant to the Offering within sixty (60) days from the
date hereof (the "Offering Registration Statement") and no notice need be
provided by the Placement Agent or other Holders of the Warrant Securities. The
obligation to register the Warrant Securities pursuant to this Section 7.2 shall
be subject to the same piggyback registration cutbacks and holdbacks to which
registration of the warrant shares are subject to under the Warrants issued to
the purchasers of securities in the Offering; provided, however, that no
registration cutbacks or holdbacks shall apply to the registration of the
Warrant Security pursuant to the Offering Registration Statement.

                                       6
<PAGE>

         Notwithstanding the provisions of this Section 7.2, the Company shall
have the right at any time after it shall have given written notice pursuant to
this Section 7.2 (irrespective of whether a written request for inclusion of any
such securities shall have been made) to elect not to file any such proposed
registration statement, or to withdraw the same after the filing but prior to
the effective date thereof.

         7.3 Covenants of the Company with Respect to Registration. In
connection with any registration under Section 7.2 hereof, the Company covenants
and agrees as follows:

         (a) The Company shall furnish each Holder desiring to sell Warrant
Securities such number of prospectuses as shall reasonably be requested.

         (b) The Company shall pay all costs (excluding fees and expenses of the
Holder(s)' counsel and any underwriting or selling commissions), fees and
expenses in connection with all registration statements filed pursuant to
Section 7.2 hereof including, without limitation, the Company's legal and
accounting fees, printing expenses, blue sky fees and expenses.

         (c) The Company will take all necessary action which may be required in
qualifying or registering the Warrant Securities included in a registration
statement for offering and sale under the securities or blue sky laws of such
states as reasonably are requested by the Holder(s), provided that the Company
shall not be obligated to execute or file any general consent to do business
under the laws of any such jurisdiction.

                                       7
<PAGE>

         (d) The Company shall indemnify the Holder(s) of the Warrant Securities
to be sold pursuant to any registration statement and each person, if any, who
controls such Holders within the meaning of Section 15 of the Act or Section
20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
from and against any and all loss, claim, damage, expense or liability
(including all expenses reasonably incurred in investigating, preparing or
defending against any claim whatsoever) to which any of them may become subject
under the Act, the Exchange Act or otherwise, arising from such registration
statement.

         (e) The Holder(s) of the Warrant Securities to be sold pursuant to a
registration statement, and their successors and assigns, shall severally, and
not jointly, indemnify the Company, its officers and directors and each person,
if any, who controls the Company within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act, from and against any and all loss, claim,
damage, expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished in writing by or on behalf of such Holders, or their
successors or assigns, for specific inclusion in such registration statement.

         (f) Nothing contained in this Agreement shall be construed as requiring
the Holder(s) to exercise their Warrants prior to the initial filing of any
registration statement or the effectiveness thereof.

                                       8
<PAGE>

         (g) If the relevant offering is an underwritten offering, the Company
shall furnish to each Holder participating in the offering and to each
underwriter a signed counterpart, addressed to such Holder or underwriter, of
(i) an opinion of counsel to the Company dated the date of the closing under the
underwriting agreement, and (ii) a "cold comfort" letter dated the date of the
closing under the underwriting agreement signed by the independent public
accountants who have issued a report on the Company's financial statements
included in such registration statement, in each case covering substantially the
same matters with respect to such registration statement (and the prospectus
included therein) and, in the case of such accountants' letter, with respect to
events subsequent to the date of such financial statements, as are customarily
covered in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities.

         (h) The Company shall deliver promptly to each Holder participating in
the offering and requesting the correspondence and memoranda described below and
the managing underwriter, if any, copies of all correspondence between the
Commission and the Company and its counsel or auditors and all memoranda
relating to discussions with the Commission or its staff with respect to the
registration statement and permit each Holder and underwriter to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonably
necessary to comply with applicable securities laws or rules of the NASD. Such
investigation shall include access to books, records, and properties and
opportunities to discuss the business of the Company with its officers and
independent auditors, all to such reasonable extent and at such reasonable times
and as often as any such Holder shall reasonably request.

                                       9

         8. Adjustments to Exercise Price and Number of Securities. For purposes
of this Section 8, references to Common Stock shall also include common stock
equivalents (including but not limited to shares of Class B Common Stock, par
value $.0001, of the Company) ("Common Stock Equivalents"); provided, that
Common Stock Equivalent shall not include any securities that are defined in
Section 8.2(b)(i) as Convertible Securities.

         8.1 Stock Splits, Etc. The number and kind of securities purchasable
upon the exercise of the Warrants and the Exercise Price shall be subject to
adjustment from time to time upon the happening of any of the following. In case
the Company shall (a) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (b) subdivide its outstanding shares of Common Stock into a greater
number of shares, (c) combine its outstanding shares of Common Stock into a
smaller number of shares of Common Stock, or (d) issue any shares of its capital
stock in a reclassification of the Common Stock, then the number of Warrant
Securities purchasable upon exercise of the Warrants immediately prior thereto
shall be adjusted so that the Holder shall be entitled to receive the kind and
number of Warrant Securities or other securities of the Company which it would
have owned or have been entitled to receive had such Warrant been exercised in
advance thereof. Upon each such adjustment of the kind and number of Warrant
Securities or other securities of the Company which are purchasable hereunder
pursuant to this Section 8.1, the Holder shall thereafter be entitled to
purchase the number of Warrant Securities or other securities resulting from
such adjustment at an Exercise Price per Warrant Security or other security
obtained by multiplying the Exercise Price in effect immediately prior to such
adjustment by the number of Warrant Securities purchasable pursuant hereto
immediately prior to such adjustment and dividing by the number of Warrant
Securities or other securities of the Company resulting from such adjustment. An
adjustment made pursuant to this paragraph shall become effective immediately
after the effective date of such event retroactive to the record date, if any,
for such event.

                                       10
<PAGE>

         8.2 Anti-Dilution Provisions. The Exercise Price and the number of
Warrant Securities issuable hereunder and for which the Warrant is then
exercisable pursuant to Section 1 hereof shall be subject to adjustment from
time to time as provided in this Section 8.2. In the event that any adjustment
of the Exercise Price as required herein results in a fraction of a cent, such
Exercise Price shall be rounded up or down to the nearest cent.

         (a) Adjustment of Exercise Rate. If and whenever the Company issues or
sells, or in accordance with this Section 8.2 hereof is deemed to have issued or
sold, any shares of Common Stock for a consideration per share less than the
then Exercise Price or for no consideration (such lower price, the "Base Share
Price" and such issuances collectively, a "Dilutive Issuance"), then, the
Exercise Price shall be reduced to equal the Base Share Price; provided, that
for purposes hereof, all shares of Common Stock that are issuable upon
conversion, exercise or exchange of Common Stock Equivalents shall be deemed
outstanding immediately after the issuance of such Common Stock Equivalents.
Such adjustment shall be made whenever such shares of Common Stock or Common
Stock Equivalents are issued.

                                       11
<PAGE>

         (b) Effect on Exercise Price of Certain Events. For purposes of
determining the adjusted Exercise Price under Section 8.2 hereof, the following
will be applicable:

             (i) Issuance of Rights or Options. If the Company in any manner
issues or grants any warrants, rights or options, whether or not immediately
exercisable, to subscribe for or to purchase Common Stock or other securities
exercisable, convertible into or exchangeable for Common Stock ("Convertible
Securities") (such warrants, rights and options to purchase Common Stock or
Convertible Securities are hereinafter referred to as "Options") and the
effective price per share for which Common Stock is issuable upon the exercise
of such Options is less than the Exercise Price ("Below Base Price Options"),
then the maximum total number of shares of Common Stock issuable upon the
exercise of all such Below Base Price Options (assuming full exercise,
conversion or exchange of Convertible Securities, if applicable) will, as of the
date of the issuance or grant of such Below Base Price Options, be deemed to be
outstanding and to have been issued and sold by the Company for such price per
share and the maximum consideration payable to the Company upon such exercise
(assuming full exercise, conversion or exchange of Convertible Securities, if
applicable) will be deemed to have been received by the Company. For purposes of
the preceding sentence, the "effective price per share for which Common Stock is
issuable upon the exercise of such Below Base Price Options" is determined by
dividing (x) the total amount, if any, received or receivable by the Company as
consideration for the issuance or granting of all such Below Base Price Options,
plus the minimum aggregate amount of additional consideration, if any, payable
to the Company upon the exercise of all such Below Base Price Options, plus, in
the case of Convertible Securities issuable upon the exercise or conversion of
such Below Base Price Options, the minimum aggregate amount of additional
consideration payable upon the exercise, conversion or exchange thereof at the
time such Convertible Securities first become exercisable, convertible or
exchangeable, by (y) the maximum total number of shares of Common Stock issuable
upon the exercise of all such Below Base Price Options (assuming full conversion
of Convertible Securities, if applicable). No further adjustment to the Exercise
Price will be made upon the actual issuance of such Common Stock upon the
exercise of such Below Base Price Options or upon the exercise, conversion or
exchange of Convertible Securities issuable upon exercise of such Below Base
Price Options.

                                       12
<PAGE>

             (ii) Issuance of Convertible Securities. If the Company in any
manner issues or sells any Convertible Securities, whether or not immediately
convertible (other than where the same are issuable upon the exercise of
Options) and the effective price per share for which Common Stock is issuable
upon such exercise, conversion or exchange is less than the Exercise Price, then
the maximum total number of shares of Common Stock issuable upon the exercise,
conversion or exchange of all such Convertible Securities will, as of the date
of the issuance of such Convertible Securities, be deemed to be outstanding and
to have been issued and sold by the Company for such price per share and the
maximum consideration payable to the Company upon such exercise (assuming full
exercise, conversion or exchange of Convertible Securities, if applicable) will
be deemed to have been received by the Company. For the purposes of the
preceding sentence, the "effective price per share for which Common Stock is
issuable upon such exercise, conversion or exchange" is determined by dividing
(x) the total amount, if any, received or receivable by the Company as
consideration for the issuance or sale of all such Convertible Securities, plus
the minimum aggregate amount of additional consideration, if any, payable to the
Company upon the exercise, conversion or exchange thereof at the time such
Convertible Securities first become exercisable, convertible or exchangeable, by
(y) the maximum total number of shares of Common Stock issuable upon the
exercise, conversion or exchange of all such Convertible Securities. No further
adjustment to the Exercise Price will be made upon the actual issuance of such
Common Stock upon exercise, conversion or exchange of such Convertible
Securities.

                                       13
<PAGE>

             (iii) Change in Option Price or Conversion Rate. If there is a
change at any time in (x) the amount of additional consideration payable to the
Company upon the exercise of any Options; (y) the amount of additional
consideration, if any, payable to the Company upon the exercise, conversion or
exchange of any Convertible Securities; or (z) the rate at which any Convertible
Securities are convertible into or exchangeable for Common Stock (in each such
case, other than under or by reason of provisions designed to protect against
dilution), the Exercise Price in effect at the time of such change will be
readjusted to the Exercise Price which would have been in effect at such time
had such Options or Convertible Securities still outstanding provided for such
changed additional consideration or changed conversion rate, as the case may be,
at the time initially granted, issued or sold.

             (iv) Calculation of Consideration Received. If any Common Stock,
Options or Convertible Securities are issued, granted or sold for cash, the
consideration received therefor for purposes of this Agreement will be the
amount received by the Company therefor, before deduction of reasonable
commissions, underwriting allowances or other reasonable expenses paid or
incurred by the Company in connection with such issuance, grant or sale. In case
any Common Stock, Options or Convertible Securities are issued or sold for a
consideration part or all of which shall be other than cash, the amount of the
consideration other than cash received by the Company will be the fair market
value of such consideration, except where such consideration consists of
securities, in which case the amount of consideration received by the Company
will be the fair market value (closing bid price, if traded on any market)
thereof as of the date of receipt. In case any Common Stock, Options or
Convertible Securities are issued in connection with any merger or consolidation
in which the Company is the surviving corporation, the amount of consideration
therefor will be deemed to be the fair market value of such portion of the net
assets and business of the non-surviving corporation as is attributable to such
Common Stock, Options or Convertible Securities, as the case may be. The fair
market value of any consideration other than cash or securities will be
determined in good faith by an investment banker or other appropriate expert of
national reputation selected by the Company and reasonably acceptable to the
holder hereof, with the costs of such appraisal to be borne by the Company.

                                       14
<PAGE>

             (v) Exceptions to Adjustment of Exercise Price. Notwithstanding
anything to the contrary herein, this Section 8.2 shall not apply to the
following (A) the granting of options to employees, officers, directors or
consultants of the Company pursuant to any stock option plan or other written
compensatory agreement duly adopted by a majority of the non-employee members of
the Board of Directors of the Company or a majority of the members of a
committee of non-employee directors established for such purpose, or (B) the
exercise of any security issued by the Company in connection with the offer and
sale of the Company's securities pursuant to the Offering (including any
securities issued as compensation in connection therewith), or (C) the exercise
of or conversion of any convertible securities, options or warrants issued and
outstanding on the date hereof, provided such securities have not been amended
since the date hereof, or (D) the issuance of securities in connection with
acquisitions, joint ventures, arrangements related to the Company's operations
and strategic relationships, or other strategic investments, the primary purpose
of which is not to raise capital.

                                       15
<PAGE>

         (c) Minimum Adjustment of Exercise Price. No adjustment of the Exercise
Price shall be made in an amount of less than 1% of the Exercise Price in effect
at the time such adjustment is otherwise required to be made, but any such
lesser adjustment shall be carried forward and shall be made at the time and
together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

         9. Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to any class of common stock of the
Company), or sell, transfer or otherwise dispose of all or substantially all its
property, assets or business to another corporation and, pursuant to the terms
of such reorganization, reclassification, merger, consolidation or disposition
of assets, shares of common stock of the successor or acquiring corporation, or
any cash, shares of stock or other securities or property of any nature
whatsoever (including warrants or other subscription or purchase rights) in
addition to or in lieu of common stock of the successor or acquiring corporation
("Other Property"), are to be received by or distributed to the holders of
Common Stock of the Company, then the Holder shall have the right thereafter to
receive, upon exercise of the Warrant, the number of shares of Common Stock of
the successor or acquiring corporation or of the Company, if it is the surviving
corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a Holder of the number of shares of Common Stock for which the Warrant is
exercisable immediately prior to such event. In case of any such reorganization,
reclassification, merger, consolidation or disposition of assets, the successor
or acquiring corporation (if other than the Company) shall expressly assume the
due and punctual observance and performance of each and every covenant and
condition of this Agreement to be performed and observed by the Company and all
the obligations and liabilities hereunder, subject to such modifications as may
be deemed appropriate (as determined in good faith by resolution of the Board of
Directors of the Company) in order to provide for adjustments of Warrant
Securities for which this Agreement is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 9. For
purposes of this Section 9, "common stock of the successor or acquiring
corporation" shall include stock of such corporation of any class which is not
preferred as to dividends or assets over any other class of stock of such
corporation and which is not subject to redemption and shall also include any
evidences of indebtedness, shares of stock or other securities which are
convertible into or exchangeable for any such stock, either immediately or upon
the arrival of a specified date or the happening of a specified event and any
warrants or other rights to subscribe for or purchase any such stock. The
foregoing provisions of this Section 9 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of
assets.

                                       16
<PAGE>

         10. Exchange and Replacement of Warrant Certificates. Each Warrant
Certificate is exchangeable without expense, upon the surrender thereof by the
registered Holder at the principal executive office of the Company, for a new
Warrant Certificate of like tenor and date representing in the aggregate the
right to purchase the same number of Warrant Securities in such denominations as
shall be designated by the Holder thereof at the time of such surrender.

         Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of any Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant Certificate of like
tenor, in lieu thereof.

                                       17
<PAGE>

         11. Elimination of Fractional Interests. The Company shall not be
required to issue certificates representing fractions of shares of Common Stock
upon the exercise of the Warrants, nor shall it be required to issue scrip or
pay cash in lieu of fractional interests, it being the intent of the parties
that all fractional interests shall be eliminated by rounding any fraction up to
the nearest whole number of shares of Common Stock or other securities,
properties or rights.

         12. Reservation and Listing of Securities. The Company shall at all
times reserve and keep available out of its authorized shares of Common Stock,
solely for the purpose of issuance upon the exercise of the Warrants such number
of shares of Common Stock or other securities, properties or rights as shall be
issuable upon the exercise thereof. The Company covenants and agrees that, upon
exercise of the Warrants and payment of the Exercise Price therefor, all shares
of Common Stock and other securities issuable upon such exercise shall be duly
and validly issued, fully paid, non-assessable and not subject to the preemptive
rights of any stockholder. As long as the Warrants shall be outstanding, the
Company shall use its best efforts to cause all shares of Common Stock issuable
upon the exercise of the Warrants underlying the Warrants to be listed (subject
to official notice of issuance) on all securities exchanges, if any, on which
the Common Stock issued to the public in connection herewith may then be listed
and/or quoted on NASDAQ.

                                       18
<PAGE>

         13. Notices to Warrant Holders. Nothing contained in this Agreement
shall be construed as conferring upon the Holders the right to vote or to
consent or to receive notice as a stockholder in respect of any meetings of
stockholders for the election of directors or any other matter, or as having any
rights whatsoever as a stockholder of the Company. If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

             (a) the Company shall take a record of the holders of its shares of
Common Stock for the purpose of entitling them to receive a dividend or
distribution payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings, as indicated by the
accounting treatment of such dividend or distribution on the books of the
Company; or

             (b) the Company shall offer to all the holders of its Common Stock
any additional shares of capital stock of the Company or securities convertible
into or exchangeable for shares of capital stock of the Company, or any option,
right or warrant to subscribe therefor; or

             (c) a dissolution, liquidation or winding up of the Company (other
than in connection with a consolidation or merger) or a sale of all or
substantially all of its property, assets and business as an entirety shall be
proposed;

                                       19
<PAGE>

then, in any one or more of said events, the Company shall give written notice
of such event at least fifteen (15) days prior to the date fixed as a record
date or the date of closing the transfer books for the determination of the
stockholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, or entitled to vote on such
proposed dissolution, liquidation, winding up or sale. Such notice shall specify
such record date or the date of closing the transfer books, as the case may be.
Failure to give such notice or any defect therein shall not affect the validity
of any action taken in connection with the declaration or payment of any such
dividend, or the issuance of any convertible or exchangeable securities, or
subscription rights, options or warrants, or any proposed dissolution,
liquidation, winding up or sale.

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

         (a) If to the registered Holder of the Warrants, 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 in Section 3 hereof or
to such other address as the Company may designate by notice to the Holders.

         15. Supplements and Amendments. The Company and Rockwood may from time
to time supplement or amend this Agreement without the approval of any Holders
of Warrant Certificates (other than Rockwood) in order to cure any ambiguity, to
correct or supplement any provision contained herein which may be defective or
inconsistent with any provisions herein, or to make any other provisions in
regard to matters or questions arising hereunder which the Company and Rockwood
may deem necessary or desirable and which the Company and Rockwood deem shall
not adversely affect the interests of the Holders of Warrant Certificates.

                                       20

         16. Successors. All the covenants and provisions of this Agreement
shall be binding upon and inure to the benefit of the Company, the Holders and
their respective successors and assigns hereunder.

         17. Termination. This Agreement shall terminate at the close of
business on December 9, 2010. Notwithstanding the foregoing, the indemnification
provisions of Section 7 hereof shall survive such termination until the close of
business on December 9, 2011.

         18. Governing Law; Submission to Jurisdiction. This Agreement and each
Warrant Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of New York and for all purposes shall be construed in
accordance with the laws of said State, without giving effect to the rules of
said State governing the conflicts of laws.

         The Company, Rockwood and the Holders hereby agree that any action,
proceeding or claim against it arising out of, or relating in any way to, this
Agreement shall be brought and enforced in the courts of the State of New York
or of the United States of America for the Southern District of New York, and
irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive.
The Company, Rockwood and the Holders hereby irrevocably waive any objection to
such exclusive jurisdiction or inconvenient forum. Any such process or summons
to be served upon any of the Company, Rockwood and the Holders (at the option of
the party bringing such action, proceeding or claim) may be served by
transmitting a copy thereof, by registered or certified mail, return receipt
requested, postage prepaid, addressed to it at the address set forth in Section
14 hereof. Such mailing shall be deemed personal service and shall be legal and
binding upon the party so served in any action, proceeding or claim. The
Company, Rockwood and the Holders agree that the prevailing party(ies) in any
such action or proceeding shall be entitled to recover from the other party(ies)
all of its/their reasonable legal costs and expenses relating to such action or
proceeding and/or incurred in connection with the preparation therefor.

         19. Entire Agreement; Modification. This Agreement (including the
Engagement Agreement to the extent portions thereof are referred to herein)
contains the entire understanding between the parties hereto with respect to the
subject matter hereof and, subject to the provisions of Section 15 hereof, may
not be modified or amended except by a writing duly signed by the party against
whom enforcement of the modification or amendment is sought.

         20. Severability. If any provision of this Agreement shall be held to
be invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provision of this Agreement.

         21. Captions. The caption headings of the Sections of this Agreement

                               WARRANT CERTIFICATE

         This Warrant Certificate certifies that Duncan Capital LLC, or
registered assigns, is the registered holder of 500,000 Warrants to purchase
initially at any time from December 9, 2003 until 5:30 p.m. New York time on
December 9, 2008 (the "Expiration Date"), up to 500,000 fully-paid and
non-assessable shares of Series A Common Stock, $.0001 par value ("Common
Stock") of DynTek, Inc. a Delaware corporation (the "Company"), at the initial
exercise prices, subject to adjustment in certain events (the "Exercise Price"),
of $0.913, per share of Common Stock, upon surrender of this Warrant Certificate
and payment of the applicable Exercise Price at an office or agency of the
Company, or due exercise of Section 3.2 of the Warrant Agreement (as hereafter
defined), but subject to the conditions set forth herein and in the Warrant
Agreement dated as of December 9, 2003 between the Company and Rockwood Inc.
(the "Warrant Agreement"). Payment of the applicable Exercise Price shall be
made by certified or official bank check in New York Clearing House funds
payable to the order of the Company.

         No Warrant may be exercised after 5:30 p.m., New York time, on the
Expiration Date, at which time all Warrants evidenced hereby, unless exercised
prior thereto, shall thereafter be void.

<PAGE>

         The Warrants evidenced by this Warrant Certificate are part of a duly
authorized issue of Warrants issued pursuant to the Warrant Agreement, which
Warrant Agreement is hereby incorporated by reference herein and made a part of
this instrument and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
Company and the holders (the words "holders" or "holder" meaning the registered
holders or registered holder) of the Warrants.

         The Warrant Agreement provides that upon the occurrence of certain
events, the then applicable Exercise Price and the type and/or number of the
Company's securities issuable thereupon may, subject to certain conditions, be
adjusted. In such event, the Company will, at the request of the holder, issue a
new Warrant Certificate evidencing the adjustment in the then applicable
Exercise Price and the number and/or type of securities issuable upon the
exercise of the Warrants; provided, however, that the failure of the Company to
issue such new Warrant Certificates shall not in any way change, alter, or
otherwise impair, the rights of the holder as set forth in the Warrant
Agreement.

         Upon due presentment for registration of transfer of this Warrant
Certificate at an office or agency of the Company, a new Warrant Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants shall be issued to the transferee(s) in exchange for this Warrant
Certificate, subject to the limitations provided herein and in the Warrant
Agreement, without any charge except for any tax or other governmental charge
imposed in connection with such transfer.

         Upon the exercise of less than all of the Warrants evidenced by this
Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

         The Company may deem and treat the registered holder(s) hereof as the
absolute owner(s) of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, and of any distribution to the holder(s) hereof, and for all
other purposes, and the Company shall not be affected by any notice to the
contrary.

         All terms used in this Warrant Certificate which are defined in the
Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.
