                         REGISTRATION RIGHTS AGREEMENT

     This Registration Rights Agreement (the "Agreement"), dated as of the 4th
day of August, 2000 is entered into between INSYNQ, Inc., a Delaware corporation
(the "Company") and ONE CLICK INVESTMENTS LLC, a Washington corporation
("Holder").

     WHEREAS, there are currently outstanding 19,830,848 shares of Common Stock
of the Company;

     WHEREAS, pursuant to a Subscription Agreement dated August 4, 2000 (the
"Subscription Agreement"), by and among the Company and Holder, Holder has
purchased 200,000 shares (the "Shares") of common stock, $0.001 par value per
share (the "Common Stock"), of the Company;

     WHEREAS, pursuant to a Warrant Agreement dated August 4, 2000 (the "Warrant
Agreement"), by and among the Company and Holder, Holder has warrants to
purchase 200,000 shares of Common Stock at an exercise price of $2.00 per share;
and

     WHEREAS, in order to insure liquidity in the future the Holder wishes to
have the Shares registered and the Company wishes to grant such registration
rights.

     NOW, THEREFORE, in consideration of the mutual covenants and obligations
hereinafter set forth, the parties hereto, intending to be legally bound, agree
as follows:

     Definitions.  As used herein, the following terms have the following
     -----------
meanings:

     "Register," "registered" and "registration" refer to a registration
effected by filing a registration statement in compliance with the Securities
Act of 1933, as amended (the "Securities Act") and the declaration or ordering
by the Securities and Exchange Commission (the "Commission") of effectiveness of
the registration statement, other than any registration statement on Form S-8,
Form S-4 or as otherwise contemplated under Rule 145 of the Act.

     1.   Piggyback Registration Rights.
          -----------------------------

          (i)  If the Company at any time proposes to register any of its shares
     of Common Stock under the Act, whether of its own accord or at the demand
     of any holders of other such securities pursuant to an agreement with
     respect to the registration thereof (provided such agreement does not
     prohibit third parties from including additional securities in such
     registration), and if the form of registration statement proposed to be
     used may be used for the registration of the Shares as contemplated
     hereunder, the Company will give notice to Holder not less than 10 days nor
     more than 30 days prior to the filing of such registration statement of its
     intention to proceed with the proposed registration (the "Registration"),
     and, upon written request of the Holder made within ten (10) days after the
     receipt of any such notice (which request will specify the number of Shares
     intended to be disposed of by the Holder and state the intended method of
     disposition thereof), the Company will use its best efforts to cause all
     Shares of Holder as to which registration has been requested to be
     registered under the Act, provided that if such Registration is in
     connection with an underwritten public offering, Holder's Shares
<PAGE>

     to be included in such Registration shall be offered upon the same terms
     and conditions as applied to any other securities included in such
     Registration. Notwithstanding anything contained in this Section 1(a) to
     the contrary, the Company shall have no obligation to cause Shares to be
     registered with respect to any Shares which shall be eligible for resale
     under Rule 144 of the Act. If the Company believes it is in the best
     interests of the Company to terminate the Registration for any reason, it
     shall have no obligations to continue the Registration but shall promptly
     notify Holder of such determination.

          (b)  If a Registration is a primary registration on behalf of the
     Company and is in connection with an underwritten public offering, and if
     the managing underwriters advise the Company in writing that in their
     opinion the amount of securities requested to be included in such
     Registration (whether by the Company, the Holder, or other holders of the
     Company's securities pursuant to any other rights granted by the Company to
     participate in such Registration) exceeds the amount of such securities
     which can be successfully sold in such offering, the Company will include
     in such Registration the amount of securities requested to be included
     which in the opinion of such underwriters can be sold, in the following
     order (A) first, all of the securities the Company proposes to sell, and
     (B) second, any other securities held by holders with registration rights
     requested to be included in such Registration, pro rata among the holders
     thereof on the basis of the amount of such securities then owned by such
     holders.

          (c)  If a Registration is a secondary registration on behalf of
     holders of securities of the Company and is in connection with an
     underwritten public offering, and if the managing underwriters advise the
     Company in writing that in their opinion the amount of securities requested
     to be included in such Registration (whether by such holders, by the
     Holder, or by holders of the Company's securities pursuant to any other
     rights granted by the Company to participate in such Registration) exceeds
     the amount of such securities which can be sold in such offering, the
     Company will include in such Registration the amount of securities
     requested to be included which in the opinion of such underwriters can be
     sold, in the following order (A) first, all of the securities requested to
     be included by holders with demand registration rights who are demanding
     such Registration, pro rata among the holders thereof on the basis of the
     amount of such securities then owned by such holders, and (B) second, any
     other securities held by holders with piggyback registration rights,
     requested to be included in such Registration, pro rata among the holders
     thereof on the basis of the amount of such securities then owned by such
     holders.

     2.   Demand Registration Rights
          --------------------------

          (a)  Holder has the right to one demand registration right on or after
     November 1, 2000.  Subject to (i) the registration procedures outlined in
     Section (b) below and (ii) the Common Stock of the Company being publicly
     traded at the time of the request set forth below, the Company shall, upon
     the request of Holder,

          (b)  Prepare and file with the SEC a Registration Statement on Form
     S-3 (or any other form of registration statement on which it may file for
     registration under the

                                       2
<PAGE>

     Securities Act) registering resales of the Common Shares by the Holder from
     time to time through the over-the-counter quotation system of the Nasdaq
     Market or the facilities of any national securities exchange or the Nasdaq
     National Market if the Common Stock is then listed or quoted thereon or in
     privately-negotiated transactions. The Registration Statement shall
     register (i) all of the Common Shares and (ii) such number of additional
     shares of Common Stock as may become issuable as Common Shares as a result
     of the anti-dilution provisions of the Common Shares. The Company will use
     commercially reasonable efforts to cause the initial Registration Statement
     to be declared effective by the SEC as soon as possible after the filing
     thereof. The Company hereby agrees that it shall (i) prepare and file such
     post-amendments to the initial Registration Statement and/or such
     additional Registration Statements as may be necessary to ensure that at
     all times there shall be registered with the SEC for resale by the Holder
     from time to time as provided in this Section 2 sufficient shares of Common
     Stock to account for all Common Shares which become issuable from time to
     time with respect to the Common Shares (as a result of anti-dilution
     provisions), and (ii) cause such post-effective amendments to the initial
     Registration Statement and/or such additional Registration Statements to be
     declared effective as soon as possible after the filing thereof.

     The Company agrees to use diligent efforts to keep the Registration
Statement(s) continuously effective and usable for resale of Registration
Securities until two years (the "Effectiveness Period") from the Closing Date or
such shorter period which will terminate when all Common Shares have ceased to
be Registrable Securities.

          (c)  Registration Procedures
               -----------------------

          In connection with the Company's obligation to file Registration
     Statements as provided in Section 3 hereof, the Company will as
     expeditiously as possible:

          (i)  Prepare and file with the SEC such amendments and post-effective
     amendments to the Registration Statement, and such supplements to the
     Prospectus, as may be required by the rules, regulations or instructions
     applicable to the registration form utilized by the Company or by the
     Securities Act or rules and regulations thereunder for shelf registration
     or otherwise necessary to keep the Registration Statement effective for the
     applicable period and cause the Prospectus as so supplemented to be filed
     pursuant to Rule 424 under the Securities Act; and comply with the
     provisions of the Securities Act with respect to the disposition of all
     securities covered by such Registration Statement during the applicable
     period in accordance with the methods of disposition by the sellers thereof
     set forth in such Registration Statement or supplement to the Prospectus;

          (ii) Notify the Holder of Registrable Securities promptly, and confirm
     such advice in writing,

               (a)  when the Prospectus or any Prospectus supplement or post-
          effective amendment has been filed, and, with respect to the
          Registration Statement or any post-effective amendment, when the same
          has become effective,

                                       3
<PAGE>

                 (b)  of the issuance by the SEC of any stop order suspending
          the effectiveness of the Registration Statement or the initiation of
          any proceedings for that purpose, and

                 (c)  of the receipt by the Company of any notification with
          respect to the suspension of the qualification of the Registrable
          Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose;

          (iii)  make every reasonable effort to obtain the withdrawal of any
     order suspending the effectiveness of the Registration Statement at the
     earliest possible moment;

          (iv)   furnish, without charge, to Holder at least one conformed copy
     of the Registration Statement and any post-effective amendment thereto,
     including financial statements and schedules, all documents incorporated
     therein by reference and all exhibits (including those incorporated by
     reference);

          (v)    deliver to Holder without charge, as many copies of the
     Prospectus (including each preliminary prospectus) and any amendment or
     supplement thereto as Holder may reasonably request; the Company consents
     to the use of the Prospectus or any amendment or supplement thereto by
     Holder in connection with the offering and sale of the Registrable
     Securities covered by the Prospectus or any amendment or supplement
     thereto;

          (vi)   use its reasonable efforts to cause the Registrable Securities
     covered by the Registration Statement to be registered with or approved by
     such governmental agencies or authorities as may be necessary to enable the
     Holder thereof to consummate the disposition of such Registrable Securities
     in such jurisdictions as the Holder may reasonably specify in response to
     inquiries to be made by the Company, provided that the Company will not be
     required to qualify generally to do business in any jurisdiction where it
     is not then so qualified or to take any action which would subject it to
     general service of process in any such jurisdiction where it is not then so
     subject;

          (vii)  if any event shall occur as a result of which it is necessary,
     in the opinion of counsel for the Company, to amend or supplement the
     Prospectus in order to make the Prospectus not misleading in the light of
     the circumstances existing at the time it is delivered by Holder, prepare a
     supplement or post-effective amendment to the Registration Statement or the
     related Prospectus or any document incorporated therein by reference or
     file any other required document so that, as thereafter delivered to the
     Holders of the Registrable Securities, the Prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein not misleading;

          (viii) obtain a CUSIP number for all Registrable Securities (unless
already obtained);

                                       4
<PAGE>

          (ix)   make available for inspection during normal business hours by a
     representative of the Holder and any attorney or accountant retained by
     such representative, all financial and other records, pertinent corporate
     documents and properties of the Company, and cause the Company's officers,
     directors and employees to supply all information reasonably requested by
     Holder or any such attorney or accountant in connection with the
     Registration Statement; provided that all such records, information or
     documents shall be kept confidential by Holder or any such attorney or
     accountant unless disclosure of such records, information or documents is
     required by court or administrative order or is generally available to the
     public other than as a result of disclosure in violation of this paragraph
     (ix);

          (x)    otherwise use its best efforts to comply with all applicable
     rules and regulations of the SEC, and make generally available to its
     security holders an earnings statement satisfying the provisions of Section
     11(a) of the Securities Act (in accordance with Rule 158 thereunder or
     otherwise), no later than 45 days after the end of the 12-month period (or
     90 days, if such period is a fiscal year) beginning with the first month of
     the Company's first fiscal quarter commencing after the Effective Date,
     which statements shall cover said 12-month period;

          (xi)   if at any time an event of the kind described in Section 4(g)
     shall occur, notify Holder that the use of the Prospectus must be
     discontinued (the Company will not declare any such "black-out" periods in
     excess of twenty business days during any twelve month period, unless
     otherwise required.

          Holder agrees, as a condition to the registration obligations with
     respect to such Holder provided herein, to furnish to the Company such
     information regarding the distribution of such Registrable Securities as
     the Company may from time to time reasonably request in writing.

          Holder agrees by acquisition of such Registrable Securities that, upon
     receipt of any notice from the Company described in this paragraph 2(c),
     Holder will forthwith discontinue disposition of Registrable Securities
     until Holder's receipt of the copies of the supplemented or amended
     Prospectus contemplated by Section 2(c)(vii) hereof, or until it is advised
     in writing by the Company (which notice the Company shall give as promptly
     as possible), that the use of the Prospectus may be resumed, and has
     received copies of any additional or supplemental filings which are
     incorporated by reference in the Prospectus, and if so directed by the
     Company, Holder will deliver to the Company (at the Company's expense) all
     copies, other than permanent file copies then in Holder's possession, of
     the Prospectus covering such Registrable Securities current at the time of
     receipt of such notice.

     3.   Cooperation by the Holder.
          -------------------------

          (a)  The Holder will furnish to the Company in writing such
     information about the Holder as the Company may reasonably require from the
     Holder in connection with the preparation of the registration statement
     (and the prospectus included therein).

          (b)  The Holder will not (until further notice) effect sales of Shares
     after receipt of telegraphic or written notice from the Company to suspend
     sales to permit the Company to correct or update a registration statement
     or prospectus; the Company agrees to use commercially reasonable efforts to
     promptly prepare and file any such correction or update.  At the end of the
     period during which the Company has decided to keep a registration
     statement current and effective (and any extensions thereof), the Holder
     shall discontinue sales of Shares pursuant to the registration statement
     upon receipt of notice from the Company of its intention to remove from
     registration the Shares covered by the registration statement which remain
     unsold, and the Holder shall notify the Company of the number of Shares
     registered which remain unsold immediately upon receipt of the notice from
     the Company.

          (c)  The Holder agrees to provide the Company with written
     representations of fact about the Holder reasonably necessary to permit the
     Company and its counsel to conclude that all sales of Shares made in
     connection with the registration were made in compliance with all
     applicable securities laws, including, without limitation, the prospectus
     delivery requirements of Section 5 of the Securities Act and any applicable
     restrictions of Rules 10b-6 and 10b-7 of the Securities Exchange Act of
     1934, as amended.

If any Registration is underwritten, Holder shall (i) agree to sell its Shares
on the basis provided in any underwriting arrangement approved by the Company
and (ii) completes and executes all questionnaires, powers of attorney,
indemnities, indemnity agreements, and other documents requested thereunder;
provided that Holder shall only be required to make representations and warrants
regarding Holder and its intended method of distribution.

     4.   Expenses of Registration.

     required by any such registration, shall be borne by the Company, except
     that the costs of prospectus printing and all underwriting discounts and
     commissions attributable to Shares being sold by the Holder shall be borne
     by the Holder.  Without limiting the generality of the foregoing, the
     Company shall pay all of the following registration expenses: (a) the
     Company's internal expenses (including, without limitation, all salaries
     and expenses of its officers and employees performing legal or accounting
     duties), (b) to the extent not already incurred, the fees and expenses
     incurred in connection with the listing on an exchange, the Nasdaq Stock

     reasonably by them incurred in connection with investigating or defending
     any such claim, loss, damage, liability or action; provided, however, that
     this paragraph (b) shall apply only if (and only to the extent that) such
     statement or omission was made in reliance upon written information
     furnished to the Company in an instrument duly executed by Holder or any of
     its officers, directors, or controlling entities or individuals and stated
     to be specifically for use in such prospectus, offering circular or other
     document (or related registration statement, notification or the like) or
     any amendment or supplement thereto.

          (c)  Indemnification Proceedings.  Each party entitled to
               ---------------------------
     indemnification pursuant to this Section 13 (the "Indemnified Party") shall
     give notice to the party required to provide indemnification pursuant to
     this Section 13 (the "Indemnifying Party") promptly after such Indemnified
     Party acquires actual knowledge of any claim as to which indemnity may be
     sought, and shall permit the Indemnifying Party (at its expense) to assume
     the defense of any claim or any litigation resulting therefrom; provided
     that counsel for the Indemnifying Party, who shall conduct the defense of
     such claim or litigation, shall be acceptable to the Indemnified Party, and
     the Indemnified

                                       9

     Party may participate in such defense at such party's expense; and
     provided, further, that the failure by any Indemnified Party to give notice
     as provided in this paragraph (c) shall not relieve the Indemnifying Party
     of its obligations under Section 13 except to the extent that the failure
     results in a failure of actual notice to the Indemnifying Party and such
     Indemnifying Party is damaged solely as a result of the failure to give
     notice. No Indemnifying Party, in the defense of any such claim or
     litigation, shall, except with the consent of each Indemnified Party,
     consent to entry of any judgment or enter into any settlement which does
     not include as an unconditional term thereof the giving by the claimant or
     plaintiff to such Indemnified Party of a release from all liability in
     respect to such claim or litigation. The reimbursement required by this
     Section 13 shall be made by periodic payments during the course of the
     investigation or defense, as and when bills are received or expenses
     incurred.

     14.  Reimbursement of Expenses.
