                  such Final Judgment is stayed the amount of such judgement
                  shall not be deemed a current asset or current liability.
                  Notwithstanding the foregoing, the Issuer may have a negative

(ii) Any trade secrets of the Employer will be entitled to all of the
protections and benefits under applicable state trade secret law and any other
applicable state or federal law. If any information that the Employer deems to
be a trade secret is found by a court of competent jurisdiction not to be a
trade secret for purposes of this Agreement, such information will,
nevertheless, be considered Confidential Information for purposes of this
Agreement. The Executive hereby waives any requirement that the Employer submit
proof of the economic value of any trade secret or post a bond or other
security.

(iii) None of the foregoing obligations and restrictions applies to any part of
the Confidential Information that the Executive demonstrates was or became
generally available to the public other than as a result of a disclosure by the
Executive.

(iv) The Executive will not remove from the Employer's premises (except to the
extent such removal is for purposes of the performance of the Executive's duties
at home or while traveling, or except as otherwise specifically authorized by
the Employer) any document, record, notebook, plan, model, component, device, or
computer software or code, whether embodied in a disk or in any other form
(collectively, the "Proprietary Items"). The Executive recognizes that, as
between the Employer and the Executive, all of the Proprietary Items, whether or
not developed by the Executive, are the exclusive property of the Employer. Upon
termination of this Agreement by either party, or upon the request of the
Employer during the Employment Period, the Executive will return to the Employer
all of the Proprietary Items in the Executive's possession or subject to the
Executive's control, and the Executive shall not retain any copies, abstracts,
sketches, or other physical embodiment of any of the Proprietary Items.

(B) Employee Inventions. Each Employee Invention will belong exclusively to the
    -------------------
Employer. The Executive acknowledges that all of the Executive's writing, works
of authorship, and other Employee Inventions are works made for hire and the
property of the Employer, including any copyrights, patents, or other
intellectual property rights pertaining thereto. If it is determined that any
such works are not works made for hire, the Executive hereby assigns to the
Employer all of the Executive's right, title, and interest, including all rights
of copyright, patent and other intellectual property rights, to or in such
Employee Inventions. The Executive covenants that he will promptly:

(i) disclose to the Employer in writing any Employee Invention;

(ii) assign to the Employer or to a party designated by the Employer, at the
Employer's request and without additional compensation, all of the Executive's
right to the Employee Invention for the United States and all foreign
jurisdictions;

(iii) execute and deliver to the Employer such applications, assignments, and
other documents as the Employer may request in order to apply for and obtain
patents or other registrations with respect to any Employee Invention in the
United States and any foreign jurisdictions;

(iv) sign all other papers necessary to carry out the above obligations; and

(v) give testimony and render any other assistance but without expense to the
Executive in support of the Employer's rights to any Employee Invention.

7.3  DISPUTES OR CONTROVERSIES

The Executive recognizes that should a dispute or controversy arising from or
relating to this Agreement be submitted for adjudication to any court,
arbitration panel, or other third party, the preservation of the secrecy of
Confidential Information may be jeopardized. All pleadings, documents,
testimony, and records relating to any such adjudication will be maintained in
secrecy and will be available for inspection by the Employer, the Executive, and
their respective attorneys and experts, who will agree, in advance and in
writing, to receive and maintain all such information in secrecy, except as may
be limited by them in writing.

8.   NON-COMPETITION AND NON-INTERFERENCE
     ------------------------------------

8.1  ACKNOWLEDGMENTS BY THE EXECUTIVE

                                       6
<PAGE>

The Executive acknowledges that: (a) the services to be performed by him under
this Agreement are of a special, unique, unusual, extraordinary, and
intellectual character; (b) the Employer's business is national in scope and its
products are marketed throughout the United States; (c) the Employer competes
with other businesses that are or could be located in any part of the United
States; and (d) the provisions of this Section 8 are reasonable and necessary to
protect the Employer's business.

8.2  COVENANTS OF THE EXECUTIVE

In consideration of the acknowledgments by the Executive, and in consideration
of the compensation and benefits to be paid or provided to the Executive by the
Employer, the Executive covenants that he will not, directly or indirectly:

(a) during the Employment Period, except in the course of his employment
hereunder, and during the Post-Employment Period, engage or invest in, own,
manage, operate, finance, control, or participate in the ownership, management,
operation, financing, or control of, be employed by, associated with, or in any
manner connected with, lend the Executive's name or any similar name to, lend
Executive's credit to or render services or advice to, any business whose
products or activities compete in whole or in part with the products or
activities of the Employer; provided, however, that the Executive may purchase
or otherwise acquire up to (but not more than) one percent of any class of
securities of any enterprise (but without otherwise participating in the
activities of such enterprise) if such securities are listed on any national or
regional securities exchange or have been registered under Section 12(g) of the
Securities Exchange Act of 1934;

(b) whether for the Executive's own account or for the account of any other
person, at any time during the Employment Period and the Post-Employment Period,
solicit business of the same or similar type being carried on by the Employer,
from any person known by the Executive to be a customer of the Employer, whether
or not the Executive had personal contact with such person during and by reason
of the Executive's employment with the Employer;

(c) whether for the Executive's own account or the account of any other person
(i) at any time during the Employment Period and the Post-Employment Period,
solicit, employ, or otherwise engage as an employee, independent contractor, or
otherwise, any person who is or was an employee of the Employer at any time
during the Employment Period or in any manner induce or attempt to induce any
employee of the Employer to terminate his employment with the Employer; or (ii)
at any time during the Employment Period and for three years thereafter,
interfere with the Employer's relationship with any person, including any person
who at any time during the Employment Period was an employee, contractor,
supplier, or customer of the Employer; or

(d) at any time during or after the Employment Period, disparage the Employer or
any of its shareholders, directors, officers, employees, or agents.

For purposes of this Section 8.2, the term "Post-Employment Period" means the
one-year period beginning on the date of termination of the Executive's
employment with the Employer.

If any covenant in this Section 8.2 is held to be unreasonable, arbitrary, or
against public policy, such covenant will be considered to be divisible with
respect to scope, time, and geographic area, and such lesser scope, time, or
geographic area, or all of them, as a court of competent jurisdiction may
determine to be reasonable, not arbitrary, and not against public policy, will
be effective, binding, and enforceable against the Executive.

The period of time applicable to any covenant in this Section 8.2 will be
extended by the duration of any violation by the Executive of such covenant.

The Executive will, while the covenant under this Section 8.2 is in effect, give
notice to the Employer, within ten days after accepting any other employment, of
the identity of the Executive's employer. The Employer may notify such employer
that the Executive is bound by this Agreement and, at the Employer's election,
furnish such employer with a copy of this Agreement or relevant portions
thereof.

9.   GENERAL PROVISIONS
     ------------------

9.1  INJUNCTIVE RELIEF AND ADDITIONAL REMEDY

The Executive acknowledges that the injury that would be suffered by the
Employer as a result of a breach of the provisions of this Agreement (including
any provision of Sections 7 and 8) would be irreparable and that an award of
monetary damages to the Employer for such a breach would be an inadequate
remedy. Consequently, the Employer will have the right, in addition to any other
rights it may have, to obtain injunctive relief to restrain any breach or
threatened breach or otherwise to specifically enforce any provision of this
Agreement, and the Employer will not be obligated to post bond or other security
in seeking such relief. Without limiting the Employer's rights under this
Section 9 or any other remedies of the Employer, if the Executive breaches any
of the provisions of Section 7 or 8, the Employer will have the right to cease
making any payments otherwise due to the Executive under this Agreement.

9.2  COVENANTS OF SECTIONS 7 AND 8 ARE ESSENTIAL AND INDEPENDENT COVENANTS

The covenants by the Executive in Sections 7 and 8 are essential elements of
this Agreement, and without the Executive's agreement to comply with such
covenants, the Employer would not have entered into this Agreement or employed
or continued the employment of the Executive. The Employer and the Executive
have independently consulted their respective counsel and have been advised in
all respects concerning the reasonableness and propriety of such covenants, with
specific regard to the nature of the business conducted by the Employer.

The Executive's covenants in Sections 7 and 8 are independent covenants and the
existence of any claim by the Executive against the Employer under this
Agreement or otherwise, will not excuse the Executive's breach of any covenant
in Section 7 or 8.

If the Executive's employment hereunder expires or is terminated, this Agreement
will continue in full force and effect as is necessary or appropriate to enforce
the covenants and agreements of the Executive in Sections 7 and 8.

9.3  REPRESENTATIONS AND WARRANTIES BY THE EXECUTIVE

The Executive represents and warrants to the Employer that the execution and
delivery by the Executive of this Agreement do not, and the performance by the
Executive of the Executive's obligations hereunder will not, with or without the
giving of notice or the passage of time, or both: (a) violate any judgment,
writ, injunction, or order of any court, arbitrator, or governmental agency
applicable to the Executive; or (b) conflict with, result in the breach of any
provisions of or the termination of, or constitute a default under, any
agreement to which the Executive is a party or by which the Executive is or may
be bound.

9.4  OBLIGATIONS CONTINGENT ON PERFORMANCE

The obligations of the Employer hereunder, including its obligation to pay the
compensation provided for herein, are contingent upon the Executive's
performance of the Executive's obligations hereunder.

9.5  WAIVER

The rights and remedies of the parties to this Agreement are cumulative and not
alternative. Neither the failure nor any delay by either party in exercising any
right, power, or privilege under this Agreement will operate as a waiver of such
right, power, or privilege, and no single or partial exercise of any such right,
power, or privilege will preclude any other or further exercise of such right,
power, or privilege or the exercise of any other right, power, or privilege. To
the maximum extent permitted by applicable law, (a) no claim or right arising
out of this Agreement can be discharged by one party, in whole or in part, by a
waiver or renunciation of the claim or right unless in writing signed by the
other party; (b) no waiver that may be given by a party will be applicable
except in the specific instance for which it is given; and (c) no notice to or
demand on one party will be deemed to be a waiver of any obligation of such
party or of the right of the party giving such notice or demand to take further
action without notice or demand as provided in this Agreement.

9.6  BINDING EFFECT; DELEGATION OF DUTIES PROHIBITED

This Agreement shall inure to the benefit of, and shall be binding upon, the
parties hereto and their respective successors, assigns, heirs, and legal
representatives, including any entity with which the Employer may merge or
consolidate or to which all or substantially all of its assets may be
transferred. The duties and covenants of the Executive under this Agreement,
being personal, may not be delegated.

9.7  NOTICES

All notices, consents, waivers, and other communications under this Agreement
must be in writing and will be deemed to have been duly given when (a) delivered
by hand (with written confirmation of receipt), (b) sent by facsimile (with
written confirmation of receipt), provided that a copy is mailed by registered
mail, return receipt requested, or (c) when received by the addressee, if sent
by a nationally recognized overnight delivery service (receipt requested), in
each case to the appropriate addresses, e-mail addresses and facsimile numbers
as a party may designate by notice to the other party.

9.8  ENTIRE AGREEMENT; AMENDMENTS

This Agreement, and the option agreements issued in connection herewith, contain
the entire agreement between the parties with respect to the subject matter
hereof and supersede all prior agreements and understandings, oral or written,
between the parties hereto with respect to the subject matter hereof. This
Agreement may not be amended orally, but only by an agreement in writing signed
by the parties hereto.

9.9  GOVERNING LAW

This Agreement will be governed by the laws of the State of Colorado without
regard to conflicts of laws principles.

9.10 JURISDICTION

Any action or proceeding seeking to enforce any provision of, or based on any
right arising out of, this Agreement may be brought against either of the
parties in the courts of the State of Colorado County of Denver, and each of the
parties consents to the jurisdiction of such courts (and of the appropriate
appellate courts) in any such action or proceeding and waives any objection to
venue laid therein. Process in any action or proceeding referred to in the
preceding sentence may be served on either party anywhere in the world.

9.11 SECTION HEADINGS, CONSTRUCTION

The headings of Sections in this Agreement are provided for convenience only and
will not affect its construction or interpretation. All references to "Section"

unless otherwise specified. All words used in this Agreement will be construed

expressly provided, the word "including" does not limit the preceding words or
terms.

9.12 SEVERABILITY

If any provision of this Agreement is held invalid or unenforceable by any court
of competent jurisdiction, the other provisions of this Agreement will remain in
full force and effect. Any provision of this Agreement held invalid or
unenforceable only in part or degree will remain in full force and effect to the
extent not held invalid or unenforceable.

9.13 COUNTERPARTS

This Agreement may be executed in one or more counterparts, each of which will
be deemed to be an original copy of this Agreement and all of which, when taken
together, will be deemed to constitute one and the same agreement.

                                JABBER.COM, INC.
                       NONSTATUTORY STOCK OPTION AGREEMENT
                        UNDER THE 2000 STOCK OPTION PLAN

     This Nonstatutory Stock Option Agreement (the "Agreement") is entered into
by and between Jabber.com, Inc. (the "Company") and Rob Balgley (the
"Employee"), effective this 11th day of December, 2000.

     The Company hereby grants to the Employee an option (the "Option") under
the Jabber.com, Inc. 2000 Stock Option Plan (the "Plan") to purchase 350,700
shares of the Company's stock ("Stock") under the following terms and
conditions.

1.   Non-Statutory Stock Option. The Option shall be a Non-Statutory Stock
     Option, as defined in the Plan.

2.   Purchase Price. The purchase price of the Stock is $0.75 per share which is
     not less than the Fair Market Value of the Stock on the date of this
     Agreement.

3.   Period of Exercise. The Option will expire on the seventh anniversary of
     the effective date (the "Expiration Date") of this Agreement. The Option
     may be exercised only while the Employee is actively employed by the
     Company (or a Subsidiary Corporation or Parent Corporation, if any, of the
     Company) and as provided in Section 6, relating to termination of
     employment.

4.   Vesting.

     4.1  Vesting Schedule. The Option will vest as follows:

          (a)  None of the shares of Stock underlying this Option shall be
               vested and exercisable until the first anniversary of the date of
               this Agreement, and then only as set forth herein; and

          (b)  On each of the first, second and third anniversaries of the date
               of this Agreement, one-third of the shares of Stock underlying
               this Option shall vest and become exercisable.

          Notwithstanding the foregoing provisions of this Section 4.1 and
          subject to the following sentence, the Option granted hereunder will
          become fully exercisable and vested in the event of a "Change in
          Control." If the Company and the other party to the transaction
          constituting a Change in Control agree that the transaction is to be
          treated as a "pooling of interests" for financial reporting purposes,
          and if the transaction in fact is so treated, then the acceleration of
          exercisability will not occur to the extent that the Company's
          independent accountants and the other party's independent accountants
          each determine in good faith that the acceleration would preclude the
          use of "pooling of interests" accounting.

                                      B-1
<PAGE>

     4.2  Definition of "Change In Control". For purposes of Section 4.1, a
          "Change in Control" means the happening of any of the following:

          (a)  The consummation of a merger or consolidation of the Company with
               or into another entity or any other corporate reorganization, if
               more than 50% of the combined voting power of the continuing or
               surviving entity's securities outstanding immediately after such
               merger, consolidation or other reorganization is owned by persons
               who were not stockholders of the Company immediately prior to
               such merger, consolidation or other reorganization;

          (b)  When, during any period of 24 consecutive months during the
               existence of the Plan, the individuals who, at the beginning of
               such period, constitute the Board ("Incumbent Directors") cease
               for any reason other than death to constitute at least a majority
               thereof; provided, however, that a Director who was not a
               Director at the beginning of such 24-month period will be deemed
               to have satisfied such 24-month requirement (and be an Incumbent
               Director) if such Director was elected by, or on the
               recommendation of, or with the approval of, at least 60% of the
               Directors who then qualified as Incumbent Directors either
               actually (because they were Directors at the beginning of such
               24-month period) or by prior operation of this Section 4.2(b); or

          (c)  The approval by the shareholders of any sale, lease, exchange, or
               other transfer (in one transaction or a series of related
               transactions) of all or substantially all of the assets of the
               Company or the adoption of any plan or proposal for the
               liquidation or dissolution of the Company.

          (d)  Any transaction as a result of which any person becomes the
               "beneficial owner" (as defined in Rule 13d-3 under the Exchange
               Act of 1934 ("Exchange Act"), directly or indirectly, of
               securities of the Company representing at least 50% of the total
               voting power represented by the Company's then outstanding voting
               securities. For purposes of this section 4.2(d), the term
               "person" shall have the same meaning as when used in Section
               13(d) and 14(d) of the Exchange Act but excludes (i) a trustee or
               other fiduciary holding securities under an employee benefit plan
               of the Company or of a Parent Corporation or Subsidiary
               Corporation; (ii) a corporation owned directly or indirectly by
               the shareholders of the Company in substantially the same
               proportions as their ownership of the Stock of the Company; and
               (iii) any person having beneficial ownership of at least 50% of
               the total voting power represented by the Company's then
               outstanding voting securities on the date of the Option.

5.   Transferability. The Option is not transferable except by will or the laws
     of descent and distribution and may be exercised during the lifetime of the
     Employee only by the Employee.

6.   Termination of Employment. Except as otherwise agreed to by the Company or
     the Employee in writing, in the event that the employment of the Employee
     with the Company (and any Parent Corporation or Subsidiary Corporation) is
     terminated, the Option may be exercised (to the extent exercisable at the
     date of termination) by the Employee within three months after the date of
     termination; provided, however, that:

     (a)  If the Employee's employment is terminated because the Employee is
          disabled within the meaning of Code Section 422, the Employee shall
          have one year rather than

                                      B-2
<PAGE>

          three months to exercise the Option (to the extent exercisable at the
          date of termination).

     (b)  If the Employee dies, the Option may be exercised (to the extent
          exercisable by the Employee at the date of death) by the legal
          representative of the Employee or by a person who acquired the right
          to exercise the Option by bequest or inheritance or by reason of the
          death of the Employee, but the Option must be exercised within one
          year after the date of the Employee's death.

     (c)  If the Employee's employment is terminated for cause as defined in
          that certain Employment Agreement between the Company and Employee
          dated December 11, 2000, the Option and the Employee's right to
          exercise the Option shall terminate immediately.

     (d)  Notwithstanding the foregoing, in no event (including disability or
          death of the Employee) may the Option be exercised after the
          Expiration Date.

7.   Leaves of Absences. For purposes of this Option, Employee's service does
     not terminate when Employee goes on a military leave, a sick leave or
     another bona fide leave of absence, if the leave was approved by the
     Company in writing. But Employee's service terminates when the approved
     leave ends, unless Employee immediately returns to active work.

8.   No Guarantee of Employment. This Agreement shall in no way restrict the
     right of the Company (or any Parent Corporation or Subsidiary Corporation)
     to terminate the Employee's employment at any time.

9.   Method of Exercise. The Option may be exercised, subject to the terms and
     conditions of this Agreement, by written notice to the Company. The notice
     shall be in the form attached to this Agreement and will be accompanied by
     payment (in such form as the Company may specify) of the full purchase
     price of the shares to be issued, and in the event of an exercise under the
     terms of paragraphs 6(a) and 6(b) hereof, appropriate proof of the right to
     exercise the Option. The Company will issue and deliver certificates
     representing the number of shares purchased under the Option, registered in
     the name of the Employee (or other purchaser under paragraphs 6(a) and 6(b)
     hereof) as soon as practicable after receipt of the notice. The certificate
     shall bear the following legends:

          "These shares have been purchased for investment within the meaning of
          the Securities Act of 1933 as amended ("Act") and applicable state
          securities laws, and they may not be sold, offered for sale, pledged,
          or otherwise transferred without an effective registration statement
          under the Act and applicable state securities laws or an opinion of
          counsel satisfactory to Jabber.com, Inc. (the "Company") to the effect
          that the proposed transaction will be exempt from registration.

          The Company will furnish without charge to each shareholder upon
          request a full statement of (1) the designations, preferences,
          limitations, and relative rights of the shares of each class or series
          of stock authorized to be issued by the Company, so far as they have
          been determined, and (2) the authority of the board of directors to
          fix and determine the relative rights and preferences of subsequent
          classes or series of stock.

          The securities represented by this certificate are also subject to
          additional restrictions on transfer, as set forth in the Non-Statutory
          Stock Option Agreement between the Company and Rob Balgley, dated as
          of December 11,

                                    B-3
<PAGE>

          2000, as may be amended from time to time, copies of which will be
          furnished by the Company or any successor thereto upon request and
          without charge."

10.  Withholding. In any case where withholding is required or advisable under
     federal, state or local law in connection with any exercise by the Employee
     hereunder, the Company is authorized to withhold appropriate amounts from
     amounts payable to the Employee, or may require the Employee to remit to
     the Company an amount equal to such appropriate amounts.

11.  Changes in Capitalization, Dissolution, Liquidation and Reorganization. The
     terms of this Agreement are subject to modification upon the occurrence of
     certain events as described in the Plan.

12.  Market Stand-Off. In connection with any underwritten public offering by
     the Company of its equity securities pursuant to an effective registration
     statement filed under the Securities Act of 1933, as amended ("Securities
     Act"), including the Company's initial public offering, the Employee shall
     not directly or indirectly sell, make any short sale of, loan, hypothecate,
     pledge, offer, grant or sell any option or other contract for the purchase
     of, any option or other contract for the sale of, or otherwise dispose of
     or transfer, or agree to engage in any of the foregoing transactions with
     respect to, any Stock acquired under this Agreement without the prior
     written consent of the Company or its underwriters. Such restriction (the
     "Market Stand-Off") shall be in effect for such period of time following
     the date of the final prospectus for the offering as may be requested by
     the Company or such underwriters. In no event, however, shall such period
     exceed 180 days. The Market Stand-Off shall in any event terminate two
     years after the date of the Company's initial public offering. In the event
     of the declaration of a stock dividend, a spin-off, a stock split, an
     adjustment in conversion ratio, a recapitalization or a similar transaction
     affecting the Company's outstanding securities without receipt of
     consideration, any new, substituted or additional securities which are by
     reason of such transaction distributed with respect to any Stock subject to
     the Market Stand-Off, the Company may impose stop-transfer instructions
     with respect to such new, substituted or additional securities until the
     end of the applicable stand-off period. The Company's underwriters shall be
     beneficiaries of the agreement set forth in this Section 12.

13.  Stockholders' Agreement. Any exercise of this Option is contingent upon the
     person exercising this Option agreeing to be bound by the terms of this
     Agreement, as amended from time to time. Employee agrees that in the event
     that Employee's employment by the Company (or any Subsidiary Corporation or
     Parent Corporation) is terminated for any reason prior to the Company's
     initial public offering, that the Company (or any Subsidiary Corporation or
     Parent Corporation) shall have the right and option exercisable at any time
     within one year of such termination of employment (but not after the
     Company's initial public offering), to repurchase any Stock acquired upon
     exercise of this Option at a purchase price equal to the greater of the
     price paid therefor by the Employee or the then fair value of the Stock as
     determined by the Company's Board of Directors.

14.  Incorporation of Plan. This Agreement is made pursuant to the provisions of
     the Plan, which Plan is incorporated by reference herein. Terms used herein
     shall have the meaning employed in the Plan unless the context clearly
     requires otherwise. In the event of a conflict between the provisions of
     the Plan and the provisions of this Agreement, the provisions of the Plan
     shall govern.

15.  Severability. In the event any provision of this Agreement shall be held
     illegal or invalid for any reason, the illegality or invalidity shall not
     affect the remaining parts of the Agreement, and the Agreement shall be
     construed and enforced as if the illegal or invalid provision had not been
     included.

16.  Compliance with the Code. The Option is intended to qualify as an
     "Non-Statutory stock option" under Code Section 422. If any provision of
     this Agreement is susceptible to more than one

                                      B-4
<PAGE>

     interpretation, such interpretation shall be given thereto as is consistent
     with the Option being treated as an Non-Statutory stock option under the
     Code.

                        INCENTIVE STOCK OPTION AGREEMENT
                        UNDER THE 2000 STOCK OPTION PLAN

     This Incentive Stock Option Agreement (the "Agreement") is entered into by
and between Jabber.com, Inc. (the "Company") and Rob Balgley (the "Employee"),
effective December 11, 2000.

     The Company hereby grants to the Employee an option (the "Option") under
the Jabber.com, Inc. 2000 Stock Option Plan (the "Plan") to purchase 399,300
shares of the Company's stock ("Stock") under the following terms and
conditions.

1.   Incentive Stock Option. The Option shall be an Incentive Stock Option, as
     defined in the Plan.

2.   Purchase Price. The purchase price of the Stock is $0.75 per share which is
     not less than the Fair Market Value (110% of the Fair Market Value in the
     case of a Significant Shareholder) of the Stock on the date of this
     Agreement.

3.   Period of Exercise. The Option will expire on the seventh anniversary of
     the effective date (the "Expiration Date") of this Agreement. The Option
     may be exercised only while the Employee is actively employed by the
     Company (or a Subsidiary Corporation or Parent Corporation, if any, of the
     Company) and as provided in Section 7, relating to termination of
     employment.

4.   Vesting.

     4.1  Vesting Schedule. The Option will vest as follows:

          (a)  None of the shares of Stock underlying this Option shall be
               vested and exercisable until the first anniversary of the
               effective date of this Option, and then only as set forth herein;
               and

          (b)  On each of the first, second and third anniversaries of the
               effective date of this Option, one-third of the shares of Stock
               underlying this Option shall vest and become exercisable.

          Notwithstanding the foregoing provisions of this Section 4.1 and
          subject to the following sentence, the Option granted hereunder will
          become fully exercisable and vested in the event of a "Change in
          Control." If the Company and the other party to the transaction
          constituting a Change in Control agree that the transaction is to be
          treated as a "pooling of interests" for financial reporting purposes,
          and if the transaction in fact is so treated, then the acceleration of
          exercisability will not occur to the extent that the Company's
          independent accountants and the other party's independent accountants
          each determine in good faith that the acceleration would preclude the
          use of "pooling of interests" accounting.

                                      C-1
<PAGE>

     4.2  Definition of "Change In Control". For purposes of Section 4.1, a
          "Change in Control" means the happening of any of the following:

          (a)  The consummation of a merger or consolidation of the Company with
               or into another entity or any other corporate reorganization, if
               more than 50% of the combined voting power of the continuing or
               surviving entity's securities outstanding immediately after such
               merger, consolidation or other reorganization is owned by persons
               who were not stockholders of the Company immediately prior to
               such merger, consolidation or other reorganization;

          (b)  When, during any period of 24 consecutive months during the
               existence of the Plan, the individuals who, at the beginning of
               such period, constitute the Board ("Incumbent Directors") cease
               for any reason other than death to constitute at least a majority
               thereof; provided, however, that a Director who was not a
               Director at the beginning of such 24-month period will be deemed
               to have satisfied such 24-month requirement (and be an Incumbent
               Director) if such Director was elected by, or on the
               recommendation of, or with the approval of, at least 60% of the
               Directors who then qualified as Incumbent Directors either
               actually (because they were Directors at the beginning of such
               24-month period) or by prior operation of this Section 4.2(b); or

          (c)  The approval by the shareholders of any sale, lease, exchange, or
               other transfer (in one transaction or a series of related
               transactions) of all or substantially all of the assets of the
               Company or the adoption of any plan or proposal for the
               liquidation or dissolution of the Company.

          (d)  Any transaction as a result of which any person becomes the
               "beneficial owner" (as defined in Rule 13d-3 under the Exchange
               Act of 1934 ("Exchange Act"), directly or indirectly, of
               securities of the Company representing at least 50% of the total
               voting power represented by the Company's then outstanding voting
               securities. For purposes of this section 4.2(d), the term
               "person" shall have the same meaning as when used in Section
               13(d) and 14(d) of the Exchange Act but excludes (i) a trustee or
               other fiduciary holding securities under an employee benefit plan
               of the Company or of a Parent Corporation or Subsidiary
               Corporation; (ii) a corporation owned directly or indirectly by
               the shareholders of the Company in substantially the same
               proportions as their ownership of the Stock of the Company; and
               (iii) any person having beneficial ownership of at least 50% of
               the total voting power represented by the Company's then
               outstanding voting securities on the date of the Option.

5.   $100,000 Limitation. Notwithstanding anything to the contrary contained in
     this Agreement, to the extent that the total Fair Market Value (determined
     as of the date of grant of an option) of shares of Stock with respect to
     which the Option and any other incentive stock options granted by the
     Company (or any Subsidiary Corporations or Parent Corporation) becomes
     exercisable for the first time during any calendar year exceeds $100,000,
     such option(s) shall be treated as a Nonstatutory Option. The preceding
     sentence shall be applied by taking options into account in the order in
     which they were granted.

6.   Transferability. The Option is not transferable except by will or the laws
     of descent and distribution and may be exercised during the lifetime of the
     Employee only by the Employee.

                                      C-2
<PAGE>

7.   Termination of Employment. Except as otherwise agreed to by the Company or
     the Employee in writing, in the event that the employment of the Employee
     with the Company (and any Parent Corporation or Subsidiary Corporation) is
     terminated, the Option may be exercised (to the extent exercisable at the
     date of termination) by the Employee within three months after the date of
     termination; provided, however, that:

     (a)  If the Employee's employment is terminated because the Employee is
          disabled within the meaning of Code Section 422, the Employee shall
          have one year rather than three months to exercise the Option (to the
          extent exercisable at the date of termination).

     (b)  If the Employee dies, the Option may be exercised (to the extent
          exercisable by the Employee at the date of death) by the legal
          representative of the Employee or by a person who acquired the right
          to exercise the Option by bequest or inheritance or by reason of the
          death of the Employee, but the Option must be exercised within one
          year after the date of the Employee's death.

     (c)  If the Employee's employment is terminated for cause, as defined in
          that certain Employment Agreement between the Company and Employee
          dated as of December 11, 2000, the Option and the Employee's right to
          exercise the Option shall terminate immediately.

     (d)  Notwithstanding the foregoing, in no event (including disability or
          death of the Employee) may the Option be exercised after the
          Expiration Date.

8.   Leaves of Absences. For purposes of this Option, Employee's service does
     not terminate when Employee goes on a military leave, a sick leave or
     another bona fide leave of absence, if the leave was approved by the
     Company in writing. But Employee's service terminates when the approved
     leave ends, unless Employee immediately returns to active work. To the
     extent that Employee's leave of absence constitutes termination under the
     regulation of the Code applicable to Incentive Stock Options, this Option
     will not terminate, but will become a Nonstatutory Option.

9.   No Guarantee of Employment. This Agreement shall in no way restrict the
     right of the Company (or any Parent Corporation or Subsidiary Corporation)
     to terminate the Employee's employment at any time.

10.  Method of Exercise. The Option may be exercised, subject to the terms and
     conditions of this Agreement, by written notice to the Company. The notice
     shall be in the form attached to this Agreement and will be accompanied by
     payment (in such form as the Company may specify) of the full purchase
     price of the shares to be issued, and in the event of an exercise under the
     terms of paragraphs 7(a) and 7(b) hereof, appropriate proof of the right to
     exercise the Option. The Company will issue and deliver certificates
     representing the number of shares purchased under the Option, registered in
     the name of the Employee (or other purchaser under paragraphs 7(a) and 7(b)
     hereof) as soon as practicable after receipt of the notice. The certificate
     shall bear the following legends:

          "These shares have been purchased for investment within the meaning of
          the Securities Act of 1933 as amended ("Act") and applicable state
          securities laws, and they may not be sold, offered for sale, pledged,
          or otherwise transferred without an effective registration statement
          under the Act and applicable state securities laws or an opinion of
          counsel satisfactory to the company to the effect that the proposed
          transaction will be exempt from registration.

          The Corporation will furnish without charge to each shareholder upon
          request a full statement of (1) the designations, preferences,
          limitations, and relative rights

                                    C-3
<PAGE>

          of the shares of each class or series of stock authorized to be issued
          by the Company, so far as they have been determined, and (2) the
          authority of the board of directors to fix and determine the relative
          rights and preferences of subsequent classes or series of stock.

          The securities represented by this certificate are also subject to
          additional restrictions on transfer, as set forth in the Incentive
          Stock Option Agreement dated as of December 11, 2000, as may be
          amended from time to time, copies of which will be furnished by
          Jabber.com, Inc. or any successor thereto upon request and without
          charge."

11.  Withholding. In any case where withholding is required or advisable under
     federal, state or local law in connection with any exercise by the Employee
     hereunder, the Company is authorized to withhold appropriate amounts from
     amounts payable to the Employee, or may require the Employee to remit to
     the Company an amount equal to such appropriate amounts.

12.  Changes in Capitalization, Dissolution, Liquidation and Reorganization. The
     terms of this Agreement are subject to modification upon the occurrence of
     certain events as described in the Plan.

13.  Market Stand-Off. In connection with any underwritten public offering by
     the Company of its equity securities pursuant to an effective registration
     statement filed under the Securities Act of 1933, as amended ("Securities
     Act"), including the Company's initial public offering, the Employee shall
     not directly or indirectly sell, make any short sale of, loan, hypothecate,
     pledge, offer, grant or sell any option or other contract for the purchase
     of, any option or other contract for the sale of, or otherwise dispose of
     or transfer, or agree to engage in any of the foregoing transactions with
     respect to, any Stock acquired under this Agreement without the prior
     written consent of the Company or its underwriters. Such restriction (the
     "Market Stand-Off") shall be in effect for such period of time following
     the date of the final prospectus for the offering as may be requested by
     the Company or such underwriters. In no event, however, shall such period
     exceed 180 days. The Market Stand-Off shall in any event terminate two
     years after the date of the Company's initial public offering. In the event
     of the declaration of a stock dividend, a spin-off, a stock split, an
     adjustment in conversion ratio, a recapitalization or a similar transaction
     affecting the Company's outstanding securities without receipt of
     consideration, any new, substituted or additional securities which are by
     reason of such transaction distributed with respect to any Stock subject to
     the Market Stand-Off, the Company may impose stop-transfer instructions
     with respect to such new, substituted or additional securities until the
     end of the applicable stand-off period. The Company's underwriters shall be
     beneficiaries of the agreement set forth in this Section 13.

14.  Stockholders' Agreement. Any exercise of this Option is contingent upon the
     person exercising this Option agreeing to be bound by the terms of this
     Agreement, as amended from time to time. Employee agrees that in the event
     that Employee's employment by the Company (or any Subsidiary Corporation or
     Parent Corporation) is terminated for any reason prior to the Company's
     initial public offering, that the Company (or any Subsidiary Corporation or
     Parent Corporation) shall have the right and option exercisable at any time
     within one year of such termination of employment (but not after the
     Company's initial public offering), to repurchase any Stock acquired upon
     exercise of this Option at a purchase price equal to the greater of the
     price paid therefor by the Employee or the then fair value of the Stock as
     determined by the Company's Board of Directors.

15.  Incorporation of Plan. This Agreement is made pursuant to the provisions of
     the Plan, which Plan is incorporated by reference herein. Terms used herein
     shall have the meaning employed in the Plan unless the context clearly
     requires otherwise. In the event of a conflict between the provisions of
     the Plan and the provisions of this Agreement, the provisions of the Plan
     shall govern.

16.  Severability. In the event any provision of this Agreement shall be held
     illegal or invalid for any reason, the illegality or invalidity shall not
     affect the remaining parts of the Agreement, and the Agreement shall be
     construed and enforced as if the illegal or invalid provision had not been
     included.

17.  Compliance with the Code. The Option is intended to qualify as an
     "incentive stock option" under Code Section 422. If any provision of this
     Agreement is susceptible to more than one interpretation, such
     interpretation shall be given thereto as is consistent with the Option
     being treated as an incentive stock option under the Code.

                         WEBB INTERACTIVE SERVICES, INC.
                       NONSTATUTORY STOCK OPTION AGREEMENT
                        UNDER THE 2000 STOCK OPTION PLAN

Between:

WEBB INTERACTIVE SERVICES, INC. (the "Company") and Rob Balgley (the
"Employee"), dated December 11, 2000.

     The Company hereby grants to the Employee an option (the "Option") under
the Webb Interactive Services, Inc., 2000 Stock Option Plan (the "Plan") to
purchase 100,000 shares (the "Shares") of the Company's common stock under the
terms and conditions set forth below. The terms and conditions applicable to the
Option are as follows:

     1. Nonstatutory Stock Option. The Option shall be an Nonstatutory Stock
        -------------------------
Option, as defined in the Plan.

     2. Purchase Price - The purchase price of the shares is $3.25 per share
        --------------
which is not less than the Fair Market Value of the Shares on the date of this
Agreement.

     3. Period of Exercise - The Option will expire on the date (the "Expiration
        ------------------
Date") seven (7) years from the date of this Agreement. The Option may be
exercised only while the Employee is actively employed by the Company (or a
Subsidiary Corporation or Parent Corporation, if any, of the Company) and as
provided in Section 6, relating to termination of employment.

     The Option may be exercised for up to, but not in excess of, the amounts of
shares subject to the Option specified below, based on the Employee's number of
months of continuous employment with the Company (or a Subsidiary Corporation or
Parent Corporation, if any, of the Company) from the date hereof. In applying
the following limitations, the amount of shares, if any, previously purchased by
Employee shall be counted in determining the amount of shares the Employee can
purchase at any time in accordance with said limitations. The Employee may
exercise the Option in the amounts and in accordance with the conditions set
forth below:

          (a)  During the first 12 months of such continuous employment from the
               date of this Option, the Option may not be exercised.

          (b)  After 12 months of continuous employment from the date of this
               Option, the Option may be exercised for not in excess of one
               third (33-1/3%) of the shares originally subject to the Option;

          (c)  After 24 months of such continuous employment from the date of
               this Option, the Option may be exercised for not in excess of two
               thirds (66-2/3%) of the shares originally subject to the Option;

                                    D-1
<PAGE>

          (d)  At the expiration of 36 months of such continuous employment, the
               Option may be exercised at any time and from time to time within
               its terms in whole or in part, but it shall not be exercisable
               after the Expiration Date.

          Notwithstanding the foregoing provisions of this Section 3 and subject
          to the following sentence, the Option granted hereunder will become
          fully exercisable and vested in the event of a "Change in Control" of
          the Company's subsidiary, Jabber.com, Inc. ("Jabber"). If Jabber and
          the other party to the transaction constituting a Change in Control
          agree that the transaction is to be treated as a "pooling of
          interests" for financial reporting purposes, and if the transaction in
          fact is so treated, then the acceleration of exercisability will not
          occur to the extent that Jabber independent accountants and the other
          party's independent accountants each determine in good faith that the
          acceleration would preclude the use of "pooling of interests"
          accounting.

          Definition of "Change In Control". For purposes of Section 3, a
          "Change in Control" means the happening of any of the following:

          (a)  The consummation of a merger or consolidation of Jabber with or
               into another entity or any other corporate reorganization, if
               more than 50% of the combined voting power of the continuing or
               surviving entity's securities outstanding immediately after such
               merger, consolidation or other reorganization is owned by persons
               who were not stockholders of Jabber immediately prior to such
               merger, consolidation or other reorganization;

          (b)  When, during any period of 24 consecutive months during the
               existence of the Plan, the individuals who, at the beginning of
               such period, constitute the Board ("Incumbent Directors") of
               Jabber cease for any reason other than death to constitute at
               least a majority thereof; provided, however, that a Director who
               was not a Director at the beginning of such 24-month period will
               be deemed to have satisfied such 24-month requirement (and be an
               Incumbent Director) if such Director was elected by, or on the
               recommendation of, or with the approval of, at least 60% of the
               Directors who then qualified as Incumbent Directors either
               actually (because they were Directors at the beginning of such
               24-month period) or by prior operation of this Section 3; or

          (c)  The approval by the shareholders of any sale, lease, exchange, or
               other transfer (in one transaction or a series of related
               transactions) of all or substantially all of the assets of Jabber
               or the adoption of any plan or proposal for the liquidation or
               dissolution of Jabber.

          (d)  Any transaction as a result of which any person becomes the
               "beneficial owner" (as defined in Rule 13d-3 under the Exchange
               Act of 1934 ("Exchange Act"), directly or indirectly, of
               securities of Jabber representing at least 50% of the total
               voting power represented by Jabber's then outstanding voting
               securities. For purposes of this section 3, the term "person"
               shall have the same

                                      D-2
<PAGE>

               meaning as when used in Section 13(d) and 14(d) of the Exchange
               Act but excludes (i) a trustee or other fiduciary holding
               securities under an employee benefit plan of the Company or of a
               Parent Corporation or Subsidiary Corporation; (ii) a corporation
               owned directly or indirectly by the shareholders of the Company
               in substantially the same proportions as their ownership of the
               Stock of the Company; and (iii) any person having beneficial
               ownership of at least 50% of the total voting power represented
               by the Company's then outstanding voting securities on the date
               of the Option.

     4. Transferability - This Option is not transferable except by will or the
        ---------------
laws of descent and distribution and may be exercised during the lifetime of the
Employee only by the Employee.

     5. Termination of Employment - In the event that employment of the Employee
        -------------------------
with the Company and any Subsidiary Corporations of the Company is terminated,
the Option may be exercised (to the extent exercisable at the date of
termination) by the Employee within three months after the date of termination;
provided, however, that:

          a. If the Employee's employment is terminated because the Employee is
     disabled within the meaning of Internal Revenue Code Section 422, the
     Employee shall have one year rather than three months to exercise the
     Option (to the extent exercisable at the date of termination).

          b. If the Employee dies, the Option may be exercised (to the extent
     exercisable by the Employee at the date of death) by the legal
     representative of Employee or by a person who acquired the right to
     exercise such option by bequest or inheritance or by reason of the death of
     the Employee, but the Option must be exercised within one year after the
     date of the Employee's death.

          c. If the Employee's employment is terminated for cause as defined in
     the Employment Agreement between Jabber and Employee, dated December 11,
     2000, this Option shall terminate immediately.

          d. Notwithstanding the foregoing, in no event (including disability or
     death of the Employee) may this Option be exercised after the Expiration
     Date.

     6. No Guarantee of Employment - This Agreement shall in no way restrict the
        --------------------------
right of the Company, Jabber or any other Subsidiary Corporation to terminate
Employee's employment at any time.

     7. Investment Representation; Legend - If required to comply with
        ---------------------------------
applicable federal or state securities laws, the Employee (and any other
purchaser under paragraph 5 hereof) represents and agrees that all shares of
common stock purchased by Employee under this Agreement will be purchased for
investment purposes only and not with a view to distribution or resale. In such
event, the Company may require that an appropriate legend be inscribed on the
face of any certificate issued under this Agreement, indicating that transfer of
the shares is restricted, and may place an appropriate stop transfer order with
the Company's transfer agent with respect to such shares.

     8. Method of Exercise; Use of Company Stock - The Option may be exercised,
        ----------------------------------------
subject to the terms and conditions of this Agreement, by written notice to the
Company. The notice shall be

                                      D-3
<PAGE>

in the form attached to this Agreement and will be accompanied by payment (in
such form as the Company may specify) of the full purchase price of the shares
to be issued, and in the event of an exercise under the terms of paragraph 5
hereof, appropriate proof of the right to exercise the Option. The Company will
issue and deliver certificates representing the number of shares purchased under
the Option, registered in the name of the Employee (or other purchaser under
paragraph 5 hereof) as soon as practicable after receipt of the notice.

     When exercising this Option Employee may make payment either in money or by
tendering shares of the Company Stock owned by the Employee, or by a combination
of the two. Where shares of Stock of the Company are employed to pay all or part
of the exercise price, the shares of said Stock shall be valued at their Fair
Market Value at the time of payment.

     9. Withholding - In any case where withholding is required or advisable
        -----------
under federal, state or local law in connection with any exercise by Employee
hereunder, the Company is authorized to withhold appropriate amounts from
amounts payable to Employee, or may require Employee to remit to the Company an
amount equal to such appropriate amounts.

     Employee acknowledges and understands that under the provisions of the
Internal Revenue Code as presently in effect, the Employee will have taxable
compensation income at the date of exercise of the Option equal to the
difference between the purchase price under the Option and the then Fair Market
Value of the Stock. Employee specifically agrees that as a condition to
permitting exercise, the Company may require that appropriate arrangements for
withholding be made with the Employee as provided above.

     10. Merger, Consolidation or Acceleration Event - The terms of this
         -------------------------------------------
Agreement are subject to modification upon the occurrence of certain events as
described in of the Plan.

     11. Incorporation of Plan - This Agreement is made pursuant to the
         ---------------------
provisions of the Plan, which Plan is incorporated by reference herein. Terms
used herein shall have the meaning employed in the Plan, unless the context
clearly requires otherwise. In the event of a conflict between the provisions of
the Plan and the provisions of this Agreement, the provisions of the Plan shall
govern.
